Pin Hole Camera

Pin hole camera was invented by a Muslim scientist ibn-al-haitham. An Egyptian polymath (born in Iraq) whose research in geometry and optics was influential into the 17th century; established experiments as the norm of proof in physics (died in 1040). Another inventor is the tenth century optician and physicist Abu Ali al-Hassan ibn al-Hassan ibn al-Haytham, simply known as al-Haytham, who invented the pinhole camera and discovered how the eye works. The ancient Greeks thought our eyes emitted rays, like a laser, which enabled us to see. The first person to realize that light enters the eye, rather than leaving it, was the 10th-century Muslim mathematician, astronomer and physicist Ibn al-Haytham. He invented the first pinhole camera after noticing the way light came through a hole in window shutters. The smaller the hole, the better the picture, he worked out, and set up the first Camera Obscura (from the Arab word qamara for a dark or private room). He was also credited with being the first man to shift physics from a philosophical activity to an experimental one. Pinhole cameras are one of the earliest styles of camera ever created. So what is a pinhole camera? It is essentially a small-enclosed box with a tiny hole placed on one of the sides. When light is allowed to entire through the tiny hole, an image of the object directly outside the hole is projected onto the opposite side of the box. We will explore pinhole camera history a little deeper so you learn more about how they first came into being. Many scientists and others observed and wrote about the phenomenon from the ancient Chinese to the Greeks. But it wasn't until the 11th century that someone actually wrote about the principals of the pinhole camera and created the camera obscura to study it. Ibn al-Haytham wrote his â€Å"Book of Optics† in 1021, and created his own pinhole camera, then later the camera obscura. Al-Haytham discovered he could sharpen his reflected, inverted image by shrinking the pinhole or aperture. Essentially, a pinhole camera is a light-tight box, usually rounded like an oatmeal box, with a pinhole in one side. The image outside the camera is projected through the pinhole where it is reversed and shown upside down on the rear of the box. With no film yet available to record the image, al-Haytham constructed the camera obscura, which is a room-sized pinhole camera where the observer can get inside the apparatus and observe the image. For hundreds of years, people used the camera obscura/pinhole camera to draw or paint the image projected. They used people, animals and landscapes as their models. While these images were not exact, they were an important step on the way to photography, because the pinhole camera served as a model for the first cameras. Discarded as quaint for many years, pinhole cameras first made a comeback with artists in the 1960s. Since then, they have become the focus of hobbyists, Cub Scout packs and other educational venues. Since all it takes to build one is an oatmeal box and some light-sensitive paper or film, the pinhole camera can teach children about physics, light and photography with a little bit of the old â€Å"gosh, wow† effect. Using the pinhole technique is one of the most authentic ways to record photographic images. The technique is based on the principle of the camera obscura which is centuries old. Basically it's nothing more then a lightproof box with, in the middle of one side, a tiny little hole instead of a lens. The light works its way through the pinhole right into the enclosed room and that is how at the opposite side of the pinhole an image appears which is upside down. We can preserve the image by putting material which is sensitive to light at the side where the image shows up and develop it after exposure. Al hazen (Ibn Al-Haytham), a great authority on optics in the Middle Ages who lived around 1000AD, invented the first pinhole camera, (also called the Camera Obscura} and was able to explain why the images were upside down. The first casual reference to the optic laws that made pinhole cameras possible, as observed and noted by Aristotle around 330 BC, who questioned why the sun could make a circular image when it shined through a square hole. http://www. muslimheritage. com/topics/default. cfm? articleID=382 Made significant contributions to the principles of optics, as well as to anatomy, astronomy, engineering, mathematics, medicine, ophthalmology, philosophy, physics, psychology, visual perception, and to science in general with his introduction of the scientific method. He is sometimes called al-Basri   after his birthplace in the city of Basra in Iraq(Mesopotamia), then ruled by the Buyid dynasty of Persia. 3] Ibn al-Haytham is regarded as the father of optics for his influential The Book of Optics, which correctly explained and proved the modern intromission theory of visual perception, and for his experiments on optics, including experiments on lenses, mirrors, refraction, reflection, and the dispersion of light into its constituent colors. [4] He studied binocular vision and the moon illusion, speculated on the finite speed, rectilinear propagation and electromagnetic aspects of light,[5] and argued that rays of light are streams of energy particles[6] travelling in straight lines. [7] Ibn al-Haytham described the pinhole camera and invented the camera obscura (a precursor to the modern camera),[14]discovered Fermat's principle of least time and the law of inertia (known as Newton's first law of motion),[15] discovered the concept of momentum (part of Newton's second law of motion),[16] described the attraction between masses and was aware of the magnitude of acceleration due to gravity at a distance,[17] discovered that the heavenly bodies were accountable to the laws of physics, presented the earliest critique and reform of the Ptolemaic model, first stated Wilson's theorem in number theory, pioneered analytic geometry, formulated and solved Alhazen's problem geometrically, developed and proved the earliest general formula for infinitesimal and integral calculus using mathematical induction,[18]and in his optical research laid the foundations for the later development of telescopic astronomy,[19] as well as for themicroscope and the use of optical aids in Renaiss ance art.

Neglect of the Elderly Essay

The neglect of the elderly is an extremely important issue in today’s society. The United States especially seem to treat their senior citizens with a severe lack of respect. In most foreign countries, the elderly are treated with the utmost respect. They are looked upon as the wisest person in their family. In today’s society, it seems as if people are more concerned with their own lives than the lives of those who raised them. This is why something needs to be done. Elderly neglect is a severe problem; one that does not seem to be getting any better. So what do we do when our parents get to the age when they have difficulty taking care of themselves? It seems that the most popular solution is to put them in an adult care facility and let them be someone else’s problem. When babies are born, they cannot take care of themselves. Do parents send them to a baby care facility and let strangers take care of them? No, because that would be preposterous. We care for our children because they cannot are for themselves. Then why is it that when the elderly get to the point that they cannot take care of themselves, we send them off to be someone else’s burden? This makes absolutely no sense. We as their children should be the ones taking care of them. We can ensure that they get the care they need. We would treat them with love and respect, something that they will not get in a facility. Adult homes, senior citizen centers, and assisted living facilities are all businesses. They are controlled by money. When money is tight, so is the care given to the senior citizens. The financial restraints result in the seniors not getting the attention they so desperately need. Some seniors cannot use the restroom without assistance, which sometimes results in them having to sit in their own filth until someone can help them. Imagine not being able to use the restroom by yourself and no one will help you. You end up soiling yourself and you have to sit in your own disgust until the underpaid, overworked employee slopes into your room to unwillingly help clean you up. Is that how anyone should be treated? No, absolutely not. Adult care facilities also suffer from a high turnover rate, which breeds poor employees. These unqualified individuals hold the lives of our elderly in their hands. A prime example would be fast food employees. When you put an underdeveloped person in a high stress, low paying job, you are not going to get top notch service. You are going to find people with bad attitudes that give poor service. Over-stressed and under-qualified caregivers end up giving this same type of service. This issue also tends to lead to elderly abuse, which is another major issue. But why do these people abuse the elderly? Even more puzzling is why do family members abuse the elderly? It was stated that â€Å"most perpetrators of abuse are caregivers who have some history of mental illness or substance abuse, and who are economically dependent on the older adult that they are supposed to be caring for† (Garrett, 2013, para.3). Why do we as a society treat these seasoned individuals with such a lack of respect? I can only imagine that part of the problem is the frustration of the system in place at these businesses. The disgruntled workers take out their frustrations on the seniors. This lack of caring also results in the seniors not being fed properly, which can ultimately lead to severe medical conditions or death. The facilities are not the main problem. The main issue is that people have lost respect for one another. Everyone is so wrapped up in their own lives that they could care less about anyone else. Elderly neglect would improve if we as a society would recognize the importance of supporting and cherishing all things, old and new. Reference Garrett, M. (2013, April 27). Elder abuse.

Rodney King Riots Essay Example | Topics and Well Written Essays - 750 words

Rodney King Riots - Essay Example The riots caused a great deal of damage and injury and remain one of the most violent periods in the history of the city. The present research looks into the causes of the riots, the events that led up to them, the evidence that was brought forward and decisions handed down and how this news was received by the greater community. The immediate and long-term effects of the riots will be examined and the lessons learned will be explored. In 1991, a man named Rodney King was brutally beaten up by four police officers and the video recording of the incident had been publicized. The LAPD officers were put on trial for this controversial incident after the video was released. This caused it to stay in the center of the public eye. The verdicts handed down as a result of the trial amazed the public because only one officer was found guilty of the excessive use of force that all four officers were seen to take part in within the video. The other officers were released with no further charges or punishment (Los Angeles Times, April 29th 1992). The video coverage of the trials and verdicts angered the populace who perhaps felt threatened that the same thing might someday happen to them. They reacted in masses as hundreds of Black people filled the streets to share their anger and disbelief. This negative emotion fed on itself and began to tip over into violence. \ The result was the riots which have jarred the nerves of eve ryone involved. Three days of violence followed. Four thousand National Guardsmen were deployed to re-establish law and order. Live news television coverage showed fires raging in various parts of the city started by the rioters. People were rioting and looting and assaulting innocent bystanders leading to utter havoc in the heart of the city. By the time the riots were brought under control, the death toll was 50 and more than 4,000 people were injured. Property damage was assessed at $1 billion and 12,000

Summary of an article - Essay Example The Digital Immigrants however defines the older population that is introduced to the technology at their old age. Resistance and challenges of old age learning have been barriers to the digital immigrant’s knowledge of technology and they still rely on traditional techniques in their interactions with the young generation. The difference is significant to the education sector in which the Digital Natives are the learners while the Digital Immigrants are the educators. Reliance on traditional techniques for education has been ineffective and the Native’s negative attitude towards traditional methods explains this. On the contrary, the Natives, for example, prefer parallel initiatives and multi tasking. They also over rely on the digital media that influence their available time for learning and their approach to learning while the Immigrants have failed to adjust their approaches to the new environment of technology. The author proposes a shift by one generation to the other’s orientation but argues for ease of adjustment of the Digital Immigrant than of the Digital Natives. A change in methods of teaching and content are recommended for bridging the gap in education and ensuring effective learning in the diversified environment (Prensky

How revolutionary was the American Revolution Essay

How revolutionary was the American Revolution - Essay Example British forces in Boston massacre in1770 butchered many blacks. One-third colonists remain neutral and one third supported revolution. Rest of people supported British act in colonies. Ultimately, the revolution ended in 1783 (Frey, 1999). Slaves were imported to work as labour force for Cotton and tobacco crops in southern states of America for cheap labour. Slaves did produce great output in raising the agricultural exports of America (Quarles, 1961). Blacks were ruthlessly used as labour and their culture and lifestyle saw a decline. White people of America made every effort to tease the blacks by social inequality and kept all sorts of educational facilities away from the reach of blacks (Quarles, 1961). Slave markets were introduced in America and women and children were separated from the men. This created a lot of hatred against white Americans in the hearts of black. There were no labour or social law and blacks were punished brutally for any mistakes. Slave masters sexually harassed young black women in the absence of women rights. Women were not allowed to raise voice against social and moral inequality (Frey, 1999). Inhuman policies made people to take revolutionary steps for their rights. Many events eventually led to revolution. Black African wanted to live lives as per their social and cultural values. Finally, blacks were successful to some extent to snatch their rights from American authorities (Quarles,

Method and Results - Essay Example The responses were coded and tabulated. SPSS software was used to store the data ready for analysis. The software could allow correlation of both the categorical and non-categorical variables. Consequently, it was possible for the management team of the Arizona University to find out how different factors related to the students influence the students performance (Creswell, 2008). Participants for the study were SOC 390 and SOC 391/FAS 361 students from Arizona State University. Out of the 180 students enrolled in the survey, only 166 students took part. The demographic questions of participant’s study time, alcohol intake were used in the analysis as independent variables. The amount of time the student spends studying for a typical class each week, which was measured in hours. The dependent variable was a measure of the student’s current GPA. The alcohol use was measured in terms of ratio whereas the GPA was measured in interval level of measurement whereas the time spend studying was measured in ratio (Patton, 2002). The study was based on a hypothesis that there is a positive correlation with studying and a higher GPA while there is a negative correlation with alcohol and students’ GPA. The data was analyzed using regression analysis in order to determine whether the GPA is dependent upon the study time and drinking of alcohol (McSpirit & Jones, 1999). This analysis was performed in order to determine the effects of the study time and alcohol drinking on the GPA. All of the 166 respondents provided answers in each category. The average GPA of student’s respondents was 3.2772 and the standard deviation was 0.51627. The mean of study time and alcohol consumption was 5.70 and 4.671 respectively whereas the standard deviation was 4.670 and 5.8437 respectively. Descriptive analysis was done to show more information on aspects such as variance, skewness, Kurtosis, standard

Gender in Public and Private Essay Example | Topics and Well Written Essays - 250 words

Gender in Public and Private - Essay Example On the other hand, private institution such as a family gives equal treatments to both genders with the aim of promoting dam growth and developments. In comparing a family (a private institution) with the government (a public institution), there are differences that can be realized. For instance, family gives equal chances to gender and treats them as one. This implies that the family treats its people equally regardless of their sexual orientation. On the other hand, government as a public institution gives priority to male gender at the expense of female. This is evidenced in the structure of government since male gender takes the topmost seats and women given lower seats (Hutchinson 3). Similarly, the government is full of force since people scramble for resources, hence locking out women or weaker gender. On the contrary, a family has a developed structure allowing distribution of resources without sidelining either gender. Despite the differences, the two institutions have a similarity since they both subordinate the role of a woman. Family as a private institution has a male as the head of the house and a woman as the helper making her play the second fiddle (Hutchinson 5). Similarly, men head most governments and appoint women to take a subordinate role (Hutchinson 5). These examples indicate that social institutions treat both genders differently in private and public

Practical Project Assessment Essay Example | Topics and Well Written Essays - 1000 words

Practical Project Assessment - Essay Example The basic idea here is to explore the various elements that compose a horror film and how these ideas may have evolved into current film making practices. The current project starts out with a clear opening image that has been extracted as a long shot except that the image has been processed to provide a certain gloom. The image has been darkened on purpose to portray a large building that is surrounded by empty trees. The camera has been kept at a low angle to look into the building’s top to provide an overwhelming sensation. The contention here was to exaggerate the size of the building and to make it appear as dark as possible. The lower right hand corner of this image is particularly dark and portrays a sense of fear of the unknown. This can be compared with ease to the manner in which typical Hollywood horror films tend to open up – an overwhelming scene of darkness is portrayed that provides the viewer with an automated response that the current film is based on h orror (Carroll, 2010;; Bennett & Beirne, 2011). In addition, the title of the project â€Å"Roommate† has been displayed in the lower reaches of the screen using a contrasting colour and capital letter only. This is intended to provide a stark contrast to the dark and gloomy background to make the inscription prominent (Carroll, 2010; Davis, 2010). The project has been provided with a sinister audio track from the very beginning which is interrupted at 0:02 for a thunder sound effect. This is followed by an inversion of the screen’s colours at 0:06 and 0:07 to portray lightning. The inverted colour screen has a shadowy figure portrayed in all white at the lower right hand side of the screen depicting a ghost. This was meant to provide the audience with a clear idea that this project is a horror film woven around ghosts. However, there is a technical error in the manner in which the lightning and thunder have been portrayed. Typically, lightning is seen first and thunde r is heard later while in the current project this has been reversed. However, it could be argued that the use of lightning and thunder is a common technique used in films to introduce sinister objectives (Landau & White, 2000; Glick, 2011; Landau & White, 2000). Thunder and lightning have been used as early as Frankenstein (1937) right down to modern day classics such as Edward Scissorhands (1990) to portray sinister elements. Most horror films are woven around the concept of thunder and lightning that is also utilised to indicate accentuation as well as climaxes in these films (Mackendrick, 2005; Rosenthal, 1980). The current film is essentially a composition of images taken from the previous term that have been placed together sequentially. As the film opens up, the protagonist is shown walking into a dorm room with clear lightning that tends to reveal the mise en scene very clearly. The dorm room has been portrayed as realistically as possible keeping the element of scattered be longings and student clutter in place. The protagonist’s makeup has been kept minimal and the costume in use is a simple pyjama with a sweater to portray an average student lurking around in a dorm. The protagonist approaches a laptop placed on the table and the camera’s focus changes over to the laptop’s screen. The transition from the protagonist’s face to the laptop screen is a straight cut so that it resembles contemporary practice (Rosenthal, 1972). The other option was to

Network and Internet Security - Essay Example A Shared Secret is a provisional access code that a company needs to generate a Portal trade Account in the eManifest Portal. The CBSA offers it to businesses that demand contact to the Portal and must be applied within 90 days of the issue time. The Shared Secret comes in handy to substantiate and validate a customer when generating an eManifest Portal company Account. Only the CBSA and the certified representative of the business have contact to this information. The Kerberos protocol is planned to present steadfast verification over open and unprotected networks where communications linking the hosts belonging to it may tempered. Nevertheless, one should be aware that Kerberos does not grant any guarantees if the machines in use are susceptible: the validation servers, submission servers and customers must be kept continuously updated so that the legitimacy of the requesting users and suppliers can be guaranteed. Kerberos protocol endeavors to avert the client's password from bein g maintained in its unencrypted mode, even in the verification server database. Bearing in mind that every encryption algorithm applies its individual key length, it is apparent that, if the consumer is not to be required to use a diverse password of a preset size for each encryption technique supported, the encryption keys cannot be the passwords. For these bases the string2key application has been introduced. It transforms an unencrypted code word into an encryption key appropriate for the sort of encryption to be utilized. This function is referred every time a user alters code word or enters it for verification. The string2key is coined as a hash function, implying that it is permanent: given that an encryption key cannot establish the secret word which created it. One-time password verification scheme (OTP). The system offers authentication for system access and further applications entail authentication, which is sheltered against flaccid attacks based on rerunning held reusab le passwords. OTP developed from the S/KEY: a brand name of Bellcore. The utilization of the OTP method only present buffers against replay aggression. It does not grant the seclusion of transmitted information, and neither does it guard against active attacks. Active aggression against TCP connections are identified to be there in the contemporary Internet (Kling, 1996). The triumph of the OTP system to guard host systems is reliant on the non-invertability of the protected hash functions applied (Carver, 2007). None of the hash algorithms have ever since been wrecked, but it is usually assumed that MD4 is less strong compared to MD5. If a server supports several hash algorithms, it is merely as protected as the weakest algorithm. There are two methods of productively and safely implementation of OTP tokens: structural design of the token execution and physical safety of the tokens. Regarding architecture, the first reflection is placement of the token in the system. The most secur e application of OTP tokens is for logging in at workplaces locally or for reaching an internal network after a firewall. In an in-house network, whereby all servers are under watch (distinct from the open Internet) an MITM (Man in the Middle) assault is not as probable (Neuman, 2008). However SSL alone can't prevent a man-in-the-middle assault. SSL with joint authentication in place can offer some defense since both

Grief Counseling and Process Intervention Essay Example for Free

Grief Counseling and Process Intervention Essay Abstract Grief comes in different forms and affects each person differently. Webster’s dictionary describes grief as â€Å"deep sadness caused especially by someones death, a cause of deep sadness, and trouble or annoyance†. Grief is associated with loss; loss of people, place, or thing. It is a universal experience that happens to all life. In multicultural counseling a counselor should be able to effectively treat and deal with the issues of grief, as they relate to divers groups. The boundaries between normal and complicated grief is a process. The factors of cultural, social and religious influence, also influences the grief and the level of anxiety that is raised due to that grief. Different people behave differently on the same sort of loss, and this makes it important to understand the impact which the loss has on the person. This diversity warrants further research on the topic of grief counseling and process interventions which have to be chosen in different circumstances with different people. Grief Counseling and Process Intervention Grief is a common reality of everyone’s life and almost all have to go through a phase where the loss is too big to handle. Altmaier (2011) states that, the strength of anxiety, stress and grief from a loss depends on the closeness and importance of that lost thing in the life of the person. Many researchers (Ober, et al., 2012; Howarth, 2011; Breen, 2011) have highlighted that death is one of the typical forms of complex loss that most people experienced at least once in their lives. The bereavement of loss of life can be far more devastating to an individual’s behavior and social functioning than any other type of losses. Such bereavement is common in  all cultures and there can seldom be a person who is not disturbed about the loss of a loved one (Howarth, 2011). However, the social detachment and the level of anxiety and depression after the loss can vary from culture to culture, closeness of relation with the deceased one, and the nature of the person. For this reason group counselors have to study and understand the nature and level of grief in order to use the correct strategy and process intervention for grief recovery (Altmaier, 2011). Discussion The term ‘best practices’ has been used in relation with group counseling to analyze the practices that are mostly applicable with people in grief (Kato Mann, 2009). However, several researchers (Baier Buechsel, 2012; Ober, 2011) have canceled out this term and claimed that each case would stand different and unique from the other. Because of this, generalizing the grief counseling process and intervention can be unsuccessful. Understanding the varied state of mind and grief symptoms of anger, depression, loneliness, anxiety and other symptoms are necessary for group counseling (Baier Buechsel, 2012). The Impact of Loss and Bereavement The research of Sussman (2011) founds that the grief and bereavement after a loss has different impacts on males, females and children. It has been discovered that men cope with a loss and their state of depression more quickly than women and children. The beginning of this fact can be related to the natural characteristics and the sensitivity of each individual, which is greater in women and children than in men. Stroebe, et al., (2009) separated the impact of loss into three phases and has illustrated that every individual that has experienced a loss will go through these three phases. The first phase is the instant shock where the person is in a mid-state of accepting the loss. Many people take a long time to accept the fact that a certain loss has occurred (Stroebe, Stroebe, Hansson, 2009). This has been a common view in the cases of deaths of loved ones, particularly with females and young children. This stage has the first reactions of mourning, yelling, protesting, showing anger and frustration loudly and not welcoming the occurrence of the loss (Howarth, 2011). In the second phase the loss is accepted mentally, but there remains the after  effects of the loss, in the form of social impairment and detachment of the person from the social group and/or preferring to be alone (Stroebe, Stroebe, Hansson, 2009). This is the phase where the counselors needs to get involved and observe the symptoms of the person and the duration of the loss event to know the technique and structure that needs to be used in such a situation Higgins (2009). The third phase of acceptance, is on in which the person accepts the loss and develops the belief that nothing can change the reality and life has to move on (Stroebe, Stroebe, Hansson, 1999). Allumbach Hoyt (2009) focuses the fact that grief counseling should not be stopped early in this phase, as there are chances that the patient could return to the second phase again (Allumbach Hoyt, 2009). The concept of cognitive therapy is introduced to be sure that the complete transaction of the person in grief takes place from the second phase of emotional distress and pain to the third phase of recovering and moving on with the life by suppressing the memories of the loss person or thing (Altmaier, 2011). A complex perspective of the grief loss is in the context of young children. Malkinson (2010) underlines the cognitive learning procedure of humans and explains that children from age two- five do not have a solid understanding of loss or death (Malkinson, 2010). They carry likelihood that whatever is gone will return back one day. This is typical in the case of their deceased pets, siblings or parents. As they go into adolescence they develop a better understanding of death and that the departed will not return. A loss of loved one at this stage can be very challenging because the child is already dealing with the questions of self-identity and life-direction. This type of loss can block the mindset, behavior and thinking capability of the child Higgins (2009). Process, Intervention, and Structure Several theorists have addressed the fact that after a loss people usually feel lonely and prefer to be alone as they cannot fill the space made by the loss object or person (Watson West 2006). A person being bankrupted and losing all his life savings in a flash has a high chance of getting isolated from the society and ending up as a depression patient or with physical disorders like brain tumor, high blood pressure or other disorders that happen due to stress and tension (Watson West 2006). If a therapist is consulted in such a scenario then the first thing to do is to understand  beliefs and conjectures which the person is carrying regarding the loss. They may think that people will make fun of them or they will lose their social status. They also may think that they will not be able to take care of their family and children etc. These are the thoughts that the person develops in the second phase of loss. They can become mentally and emotionally weak, not able to look at the brighter side of the scenario or what is left (Baier Buechsel, 2012). In the Task-Oriented Approach forwarded by Doel (2006), Eaton Roberts (2002) shows that the mechanism of motor performance of each individual suffering from losses processed and structured with a technique to make the person believe that the intensity and level of loss is not as big as it is perceived by the person. In his study Doel (2006) defines the practice of using volunteers who can form group with the person to be treated and the volunteers. They will act if they have not had a much greater loss and can share how they have coped with it. This has proved to be a good strategy if conducted in a proper fashion and establishing that the events described by other are similar in nature but unique from one another (Eaton Roberts, 2002). The second task is of helping the person to erase the old memories related to that person, business or any other object. The motif here is not to separate the person from the loss, but to lessen the grief and bereavement that is closely associated to the memories of the loss (Eaton Roberts, 2002). The task oriented intervention for grief counseling shows great limitations when it is implied for the grief therapy of parents who have lost their young children in an accident or been killed. Such cases were abundant after the devastating event of 9/11 and a lot of parents showed little or no recovery by the use of task oriented process and stayed in their state of depression and emotional pain. Brown (2006) has forwarded the Cognitive Behavioral Therapy (CBT) Model for the grief counseling of people in complicated bereavement like those who have experienced sudden death of a loved one, particularly their children. The ground of this intervention is due to the difference between the rational and the irrational thinking of the distressed people. Irrational thinking makes them perceive their lives to be intolerable without the existence of the deceased one (Brown, 2006). In the CBT process, close bonds are developed with such people and they are given the chance to express the effect of such a loss on their present and future.  This presumption, usually based on irrational thinking, is first replicated by other irrational support (Malkinson, 2010). For example, if a mother has lost her child then she is made to believe that her child will be remembered as the one who sacrificed his/her life and he/she would have attained a higher state in the heaven. The parallel of the irrational thinking with other irrational belief was carried out in the study of Cigno (2006) on ‘Cognitive-behavioral practice’ with 18 mothers and 11 fathers whom children became victim of the street crimes or terrorist activities. Cigno found out that 72.4% of the parents in this research showed signs of improvement and were able to enter the second phase of loss grief to the third phase. At this stage, activities of social engagement and task oriented approach can be available to ensure maximum grief recovery of those people (Cigno, 2006). The Complicated Grief Intervention Model (CGIM) To empower the counselors and the social workers in treating complicated grief, there is a need of a model that can define the approach and plan of counselors when they are dealing with a bereaved person (Morris, 2006). The grief of loss of the loved one, a major business downfall or other losses which have a great impact on the outlook of one’s life can be included in complicated grief. The counselor assesses the need and the present condition of the bereaved one in the first step of the model. This is not limited to the emotional state, but also to the practical side; the work and family responsibilities of the bereaved one that are affected by the disposition of the person. These things can be assessed by using the narrative technique and asking the people about their stories related to the lost person or object. A secondary assessment is also suggested where the friends or family members of the bereaved one are interviewed to know the extent of grief (Altmaier, 2011). When the counselor prescribes activities or medicines to the bereaved person this is the second stage is of intervention. It has been a common observation by many researchers (Watson West, 2006; Silversides, 2011; Morris (2006) that counselors are not result-oriented in their intervention. Silversides (2011) discusses that many counselors do not plan the outcome of the activity and they do not regularly evaluate the success of the activity. Because of this practice the recovery is temporary. There have been cases reported to have developed the  same state of depression and grief after the therapy was over (Silversides, 2011). For instance, if a hobby is suggested to the bereaved person to exercise, some of the questions that need to be answered are: what will be the duration of the exercise? What end results it will bring or tend to bring? How will it help the bereaved person to replicate the negative irrational thinking with positive irrational thinking? What will be the consequences of the exercise after it is discontinued for more than 6 months? What will be the approach if the person develops the same state of mind again? Answering these questions prior to starting the intervention strategy will raise the probability of achieving desired results over the anticipated time (Drenth, Herbst, Strydom, 2010). It is evident that some part of the therapy, like counseling sessions and workshops cannot last forever and they need to be stopped after some period, while few of the routine activities can be carried on for a much longer period as the person wants to. It is necessary for the social worker or counselor to understand the significance of the activities and which are for finite period, and analyze if there would be a need to prolong, modify or substitute it with another activity as per the requirement of the person (Johnsen, Dyregrov, Dyregrov, 2012). It is both natural and biblical to grieve. The reality is that no matter how happy those who have gone are, and how much they gain by the move, the loss is suffered , and trying to live in denial of this reality is not heroic but caving in to social or religious pressure that is not of God. There is much evidence that those who confront their inner pain head-on, heal quickest. Inner pain will gradually retreat when we face it, but it will keep haunting us if we run from it. â€Å"Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. All we like sheep have gone astray; we have turned everyone to his own way; and the LORD hath laid on him the iniquity of us all (Isaiah 53:4-6, KJV). Conclusion Grief is a natural occurring and almost every human goes through this phenomenon at some point of time in his or her life. The extent of grief is dependent on factors of closeness with the lost person or thing and the  rational and irrational thinking that the person has developed after the loss. The state of complex grief or bereavement occurs mostly in the case of losing the love ones and entering into the state of loneliness, anger and depression. The degree of these symptoms is more pronounced in teen agers and women. It is for this reason that counselors have to understand the nature and extent of the grief and the irrational thinking that have been developed as a result to prescribe a therapy or activity that best suits the need of the bereaved one.

The Common Problems Associated With Dams Environmental Sciences Essay

The Common Problems Associated With Dams Environmental Sciences Essay A Dam is a physical barrier constructed across a river or a waterway to control the flow of or raise the level of water. The purpose of such a construction may be flood control, irrigation needs and generation of hydroelectricity. A dam is a barrier across flowing water that obstructs, directs or slows down the flow, often creating a reservoir, lake or impoundments. Most dams have a section called a spillway or weir over which, or through which, water flows, either intermittently or continuously, and many have hydroelectric power generation systems installed. The dams are advantageous in more than a single way. Advantages of a dam are listed below: They are helpful in preventing floods. They serve as a solution to energy crises by generating hydroelectricity. They prove to be helpful in irrigation They better the water transport. And last but not the least they attract tourists. Dams are too beneficial for mankind but at the same time they are harmful too in several ways. Disadvantages of a dam are listed below: Building a dam is an expensive affair. For building a dam a huge population of nearby area is moved. The living environment of aquatic and semi aquatic flora and fauna gets disturbed in lower case. Collapse of the dam causes great damage. Fig 1 Dam [www.timboucher.com] Now in this paper we will be viewing and observing the main causes of Dam Failure along with case study for every cause. Main causes of Dam Failure are: Spillway designing error. Sliding of mountain into the dam lake. Poor maintenance especially of outlet pipes. We will be discussing all of the above mentioned causes one by one. Besides all the above causes there is one more reason due to which dams are collapsed. In technical terms it is called Deliberate Dam Failure. This happens during the course of War. When force of one country destroys the dam of other country deliberately then this is known as Deliberate Dam Failure. As this cause is nat a common cause so we would not consider this in our study. SPILLWAY DESIGN ERROR Spillway (shown in Fig 2) is a characteristic structure of a dam which is used to provide controlled release of flows of water from the dam into the downstream. Spillways release floods so that the water does not overtop and damage or even destroy the dam. There are two ways of spillways: Controlled and Uncontrolled. Controlled Spillway: It has gates which regulate the water. This design gives us an opportunity to exploit the full height of the dam and flood waters can be released as required by opening one or more gates. Uncontrolled Spillway: It does not have gates, when the water rises above the lip of the spillway it begins to be released from the reservoir. The rate of discharge of water is controlled only by the depth of water within the reservoir. All of the storage volume in the reservoir above the spillway lip can be used only for the temporary storage of floodwater, and cannot be used as water supply storage because it is normally empty. Fig 2 Spillway [www.wikipedia.com] CASE STUDY: The South Fork Dam As a case study under this cause of Dam Failure we will study the demolition of South Fork Dam which was located on Lake Conemaugh, an artificial water body located near South Park, Pennsylvania, USA. On May 31, 1889, the South Fork Dam failed and 20 million tons of water from Lake Conemaugh burst through and raced 14 miles (23 km) downstream, causing the Johnstown Flood. History of South Fork Dam The South Fork Dam was built by the Commonwealth of Pennsylvania between 1838 and 1852 as a reservoir for the canal basin in Johnstown. The dam is located 14 miles upstream from Johnstown. The Comenaugh River runs through the heart of Johnstown and it had been made narrower in order to build more structures on it banks. The river was susceptible to flooding due to ità ¢Ã¢â€š ¬Ã¢â€ž ¢s location on a flood plain. The Commonwealth of Pennsylvania sold the dam to the Pennsylvania Railroad in 1857. With the arrival of rail service in 1852, the use of the canal for delivery of goods took a downturn. The South Fork Dam was abandoned and allowed to go into a state of disrepair. In 1862, part of the culvert gave way but was never repaired. In 1879, a group of businessmen formed a company and called it the South Fork Hunting and Fishing Club. They purchased the dam with the intention of building a summer resort on Lake Comenaugh for wealthy Pittsburg families. Plans included lowering the dam in order to build a road on top and raising the level of the lake. The club continued to make alterations to the dam and in the end, the lake was 450 feet higher than Johnstown.[suit101.com] From the above abstract we can easily make out that the ill maintenance of the spillway and rising of the level of river made the condition worse and finally the continuous rain made the Dam collapsed. After the Dam gave up nearly about 20 million tons of water spilled over the dam and Jhonstown was hit without any prior warning. The water headed towards the town with a speed of nearly 40 miles per hour. The flood played havoc and made over 2,200 people lose their lives and all over damage was estimated to cost $17 million. This was the first major disaster faced by the newly-formed American Red Cross. Aid came from 18 countries across the globe. The South Fork Dam Break is shown Below[Fig 3] Beside the Spillway failure there are other causes which are responsible for the Disaster and they are: Heavy and continuous Rainfall. Rising water caused erosion of new embankment which was made up of mud and straw. Fig 3 South Fork Dam Break [www.accuweather.com] Precautions which could have saved South Fork Dam: The main cause of the break was Spillway design error. There were insufficient spillways which made the enormous amount of water to spill. If there had been more spillways then the disaster would have been avoided. The damaged parts of the dam should have been repaired. The new parts should have been made up of concrete instead of stone, mud and straw. SLIDING OF MOUNTAIN INTO THE DAM LAKE A dam is made at the base of a river and in between a valley which means that the lake or water body which is dammed has mountains on both side of it. Now as a dam is made the natural geological balance is disturbed and these mountains get loosen up and develops cracks which causes landslides to occur. These landslides pose a great threat when they fall in the lake. If a landslide of great volume falls in the lake then it raises the water level to a great extent and that too suddenly. This sudden rise makes a huge amount of water to spill over the dam causing tsunami (seiche wave). This wave brings a massive flood and destruction to the valley below which wipes a great area. CASE STUDY: The Vajont Dam As a case study under this cause of Dam Failure we will study the demolition of Vajont Dam [shown in Fig 4] which was located on Vajont River under Monte Toc, 100 km north to the Venice, Italy. It was responsible for the deaths of approximately 2,000 people in a 1963 landslide. One of the highest dams in the world, it was 262 meters (860 ft) high, 27 meters (89 ft) thick at the base and 3.4 meters (11 ft) at the top. The dam was built by SADE (Society of Adriatic Energy Corporation), the electricity supply and distribution monopolist in North-Eastern Italy. History of Vajont Dam: The construction work of the dam started in 1950. In 1959 some slides were noticed and new studies were made and the experts told SADE that the side of Mount Toc is unstable and is likely to collapse if the filling is continued. The study and experts were ignored completely. In October 1959 the construction was complete and in February 1960 SADE was authorized to start filling the basin. As soon as the filling started and reached to certain level till summers of 1960 minor land slides started taking place. But even these slides were ignored and the few journalists who raised their voice were sued. Finally on 4 of November 1960 a landslide of about 800,000 cubic meters collapsed in the lake. This made SADE to halt filling but it was started again after lowering the level by 50 meters and start building an artificial gallery. The minor slides kept on taking place and officials of SADE kept on predicting the disaster but they were ignored. On 9 October 1963 at approximately 10:35pm, the combination of drawing-down the reservoir and heavy rains triggered a landslide of about 260 million cubic meters of forest, earth, and rock, which fell into the reservoir at up to 110  km per hour (68  mph). The resulting displacement of water caused 50 million cubic meters of water to over-top the dam in a 250-metre high wave.[6] Despite this, the dams structure was largely undamaged. Approximately 1900 to 2500 people were dead and 350 families were completely wiped off. The major causes of this disaster are: The heavy 50 million cubic meter landslide into the lake which made the tsunami wave rose. The other minor land slides in the lake and in the artificial gallery. Heavy rainfall which paved the path for the disaster. Major causes for the land slides are: Disturbance in the geological balance of Mount Toc. Continuous filling of the basin. Time to time rainfall. Fig 4 Vajont Dam[wikipedia.com] Precautions which could have saved South Fork Dam: If anyhow the land slide could be prevented then the disaster might have been avoided. The landslide can be prevented by following two methods: Plantation: More and more plants on the seaward side of the mountain. The roots of the plants help in binding the rocks and soil together and prevent erosion thus land sliding. Terrace plantation is a good option. By artificial mountain binding: In this process the mountain is bound with the help steel net which prevent slides and even if land slide, the net prevent it from falling. POOR MAINTENANCE ESPECIALLY OF OUTLET PIPES Outlets came in range of designs, sizes, materials and type of control. Most of the controlling mechanisms and conduits are usually submerged and are pretty tedious to access for maintenance as well as inspection. This is the reason of negligence and some serious problems start developing. The problem can range from the control works becoming inoperable to the conduit deteriorating to the point of embankment failure. Proper inspection of the outlet usually requires advanced planning to allow outflows to be shut off and inundated areas to be pumped out. CASE STUDY: Lawn Lake Dam Now as a case study under this section we will make a thorough study of Lawn Lake Dam [Fig 5]. This dam failure occurred due to the disrepair of the outlet pipe which was located at the remote and tedious location. The continuous negligence of remotely situated leaky pipes caused the disaster when on July 15, 1982 at 6 a.m. 830,000 m3 of water exploded out of the faulty pipes. This enormous amount of water caused a flash flood and priced $31 million. History of Lawn Lake Dam: Originally the Lawn Lake was a natural lake covering a surface area of over 66,000 m3. It was situated at a height of 3,400 m in the rocky mountain. In 1903 some farmers seeking irrigation facilities out of this lake, built a dam and the covering land of the lake increased to 190,000m3. It was started in 1902 and the dam was completed in 1903. The dam increased the storage capacity of this natural water body. This dam was built in the eastern part. The water from this dam was released through the steep channel into the Big Thompson River. As the dam was built in the rocky mountain, its design was such that it made the location of outlet pipe quit remote. Bearing the negligence of officials the dam survived 80 long years. On the morning of 15 July 1982 the dam collapsed releasing 228 million gallons of water all of a sudden. This huge amount of water poured through the steep and narrow mountainside. It is said that there was tremendous sound and the earth shook. The release rate of water was 510 m3/s. Though this great aquatic rampage killed only one person camping alongside but economically the cost of this disaster was estimated to be $31 million. The water got poured in the river and hit the cascade dam resulting in downfall of the same adding more amount of water to the flood. This flood destroyed the Aspenglen campground. Then after the flood water entered the town of Estes Park and caused great damage to the downtown shops after which the flood joined Thompson River. This flood deposited an alluvial fan of debris in Horseshoe Park. Fig 5 Alluvial Fan [wikipedia.com] Precautions that could have saved the Lake Lawn Dam: Only two precautions would have saved the disastrous end of Lake Lawn Dam and they are If the dam would have been design in such a way that the outlet pipes could have been easily accessed then the repair work wonà ¢Ã¢â€š ¬Ã¢â€ž ¢t have been delayed and the leakage could have been avoided. Timely repairing work of the dam would have saved this great damage.

The Sabotaged Friendship of Authors Ernest Hemingway and Sherwood Ander

The Sabotaged Friendship of Authors Ernest Hemingway and Sherwood Anderson Ernest Hemingway, an intrinsically gifted author in his own right, owes much of his early success to the mentor he befriended and eventually estranged, Sherwood Anderson. Hemingway’s renowned knack for sabotaging personal relationships throughout his life started early with Anderson. The two writers met in a suburb of Chicago named Oak Park while Hemingway worked as an editor for the Cooperative Commonwealth in 1919. Anderson would go on to help Ernest publish his first successful work (inspired by Sherwood’s own writing), In Our Time, but the friendship would come to an abrupt end in 1926 courtesy of Hemingway’s satirical jab at his former mentor in The Torrents of Spring. Sherwood Anderson was a relatively well-established author when he met Ernest Hemingway. Before they encountered one another, Hemingway had already read Anderson’s Winesburg, Ohio. Ernest â€Å"was a great admirer of [Anderson’s] work, particularly those tales which had sporting scenes for their backgrounds† (Schevill 153). Whenever the two were around each other, Hemingway was always â€Å"quiet and attentive† (Fenton 104), though Ernest’s friend, Kate Smith recalled: â€Å"It probably means a storm’s brewing† (Fenton 104). Hemingway would internalize all that he learned from his time spent with Anderson in Chicago. The two shared a similar interest in â€Å"sex as a basic human drive,...the examination of youth and its distresses,†¦[and] the importance of emotion and feeling† (Fenton 148). Anderson himself denied ever influencing Hemingway’s work â€Å"as a whole† (Fenton 105). Anderson me rely recognized the talent that Hemingway possessed. Motivated by his appreciation... ...rite to him that he meant the book as a joke, though Sherwood failed to recognize the humor in it. Anderson interpreted the book as a personal insult. The relationship between the two authors was never the same. Later in 1926, the two met in Paris over drinks, but Anderson noted that Hemingway had become â€Å"too self-centered, too concerned with his own career to the exclusion of personal relationships† (Schevill 238). The rift created by the Torrents of Spring would never be mended. Over the years, Anderson remained an avid fan of Hemingway’s work, but their friendship dwindled out of existence. Sherwood Anderson inspired multitudes of young writers: Faulkner, Joyce, Hemingway, Stein, to name a few, with his simple narrative tone and colloquial settings. Anderson served as the perfect mentor in cultivating the talented minds of some of America’s finest writers.

Oil In April 2000 :: essays research papers

W A S H I N G T O N, April 6 — The good news for consumers is gas prices are anticipated to drop this summer. But the bad news is the decline will be slow. With an increase in international oil production as a backdrop, the Energy Department today dramatically revised its forecast for summer gasoline prices. The agency said prices should peak later this month and begin dropping sometime in May, averaging about $1.46 a gallon throughout the summer. Even Cheaper Fall Prices And there’s even more good news: Gasoline prices may dip lower still by fall, according to the agency. Prices may fall to a national average of $1.39 after Labor Day, the department’s Energy Information Administration said in its revised short-term forecast. â€Å"By then I expect we will have started to see some economic growth deterioration and I think from there we probably will see demand start to come under some pressure,† said Peter Beutel, president of Cameron Hanover, an energy ri sk management firm in Connecticut. â€Å"So, I think we probably will see prices closer to $1.30 or maybe even $1.25.† What Happened to the $2 Estimate? Just a month ago, the Energy Department said even with increased oil production, gasoline prices were expected to soar to a national average of as much as $1.80 a gallon and likely reach $2 a gallon in some places by July. So what’s changed between now and then? A key international oil meeting in Vienna, Austria. The EIA in its latest forecast assumed additional oil would begin hitting the U.S. market by June as a result of a decision March 28 by the Organization of Petroleum Exporting Countries. OPEC agreed to boost production by as much as 1.7 million barrels a day. Other non-OPEC producers also have said they would increase production. And production increases mean refilled petroleum stocks and lower prices for oil products including gasoline. †We are more optimistic today. Some of the tightening of the market has improved,† said EIA Administrator Jay Hakes. Nationally, the average cost of regular grade gasoline was $1.52 a gallon in March, with the average for all grades, including premium, a nickel higher, the agency said. Revisions Still 25 Percent Higher But don’t get too excited just yet. The agency’s latest revision is still 25 percent higher than summer prices a year ago. The average motorist is expected to pay about $170 more for gasoline this summer than last, according to the EIA.

Essay --

As classified by Thibodeau and Patton (2007) the six major classifications of the brain from the bottom of the brain and going upwards in direction are: â€Å"the medulla oblongata, pons, midbrain (the first three can be classified simply as the brain stem), cerebellum, diencephalon, and cerebrum. For the purpose and focus of this class, more attention will be made on specific anatomy found within those major classifications. According to Hart and Ksir, (2013) the midbrain, pons and medulla as the whole brainstem are responsible for the coordination of motor reflexes and sensory reflexes and are also listed as the general location as to which the neurotransmitters serotonin, dopamine, and norepinephrine are released. Nearly the entire amount of these neurotransmitters is produced within this proportionately small area (Hart & Ksir, 2013). A further breakdown of the reflex centers controlled by the brain stem as stated by Thibodeau and Patton, (2007) are as follows: Nuclei in the medulla contain a number of reflex centers. Of first importance are the cardiac, vasomotor, and respiratory centers. Other centers present in the medulla are for various non-vital reflexes such as vomiting, coughing, sneezing, hiccupping, and swallowing. The pons contains centers for reflexes mediated by the fifth, sixth, seventh, and eight cranial nerves†¦In addition, the pons contains the pneumotaxic centers that help regulate respiration. The midbrain, like the pons, contains reflex centers for certain centers for certain cranial nerve reflexes, for example, papillary reflexes and eye movements, mediated by the third and fourth cranial nerves, respectively. Having more neurons than all the other parts of the nervous system combined a... ...when a drug binds with a receptor in the brain, two effects can be had. The first effect is an agonist effect, in which the substance or drug is able to mimic the effect of the neurotransmitter it resembles and the second is an antagonist effect in where the substance or drug is able to fit the receptor but there is no resultant effect- in essence it blocks the receptor from accepting anything else, including the intended neurotransmitter (Hart & Ksir, 2013). As described by my previous Anatomy Professor Joseph Staley, â€Å"an agonist effect is like being able to start a Ferrari with the keys to a Honda and driving away while the antagonist effect is like getting the key to the Honda stuck in the Ferraris’ ignition and not being able to even put the real key in it and not drive it anywhere.† While it is very basic, it is also a very accurate description.

Erikson’s Theories Personal Portrait Essay

Erik Erikson’s and Lawrence Kohlberg developed several different theories that demonstrated each phase of our lives. Their theories demonstrated how each stage developed and how the stages help to make us who we are today. We develop, learn, and revolutionize through developmental and moral developments. This paper will illustrate how each developmental and moral development represents each stage of life. Erik Erikson’s stages of developmental theory consist of eight stages of development versus Lawrence Kohlberg’s six stages of moral developmental theory. Both of these theorists beliefs were different when it came to the breakdown of each stage. Erikson’s infant stage which consisted of trust vs. mistrust which is â€Å"the need for maximum comfort with minimal uncertainty to trust himself/herself, others, and the environment( Patient Teaching, 1990).† This is a stage that I cannot relate to because I do not have any memories from infancy. Kohlberg’s first stage is â€Å"obedience and punishment† which relates that a â€Å"child assumes that powerful authorities hand down a fixed set of rules which he or she must unquestioningly obey (Kohlberg, 1958b). For example, your principle in your elementary school down to your teacher is an authority figure. I relate to Kohlberg’s stage because I can remember growing up and knew that my parents, teachers, and principles were my authority figures. I knew that I must obey them and if I did not that it would result in severe punishments and sometimes multiple punishments from each individual. Being a female, a felt that I feared authority figures more than my brothers or other boys in my class. Second stage of Erickson’s was the â€Å"toddler† stage â€Å"autonomy vs shame and doubt-works to master physical environment while maintaining self esteem â€Å"The second stage occurs between 18 months and 3 years. At this point, the child has an opportunity to build self-esteem and autonomy as he or she learns new skills and right from wrong. The well-cared for child is sure of himself, carrying him or herself with pride rather than shame. During this time of the â€Å"terrible twos†, defiance, temper tantrums, and stubbornness can also appear. Children tend to be vulnerable during this stage, sometimes feeling shame and low self-esteem during an inability to learn certain skills (Erikson, 1968).† Kolberg’s second stage â€Å"Individualism and Exchange† â€Å"At this stage children recognize that there is not just one right view that is handed down by the authorities. Different individuals have different viewpoints (Kohlberg, 1963, p. 24).† Both Erikson’s and Kohlberg’s theory can be a demonstrated at an early childhood stage. One learned that they were an individual and that one had to respect authority figures. I can remember a time that I was in preschool and I was asked why I took another child’s crayon. I remember stating to the teacher that I wanted my crayons to remain new. I was already developing a sense of being selfish and using others. That was not the route to take which was expressed to me by both my teacher and my parents. The third stage is â€Å"Initiative vs. Guilt† which demonstrates â€Å"purpose† â€Å"During this period we experience a desire to copy the adults around us and take initiative in creating play situations. We make up stories with Barbie’s and Ken’s, toy phones and miniature cars, playing out roles in a trial universe, experimenting with the blueprint for what we believe it means to be an adult. We also begin to use that wonderful word for exploring the world—†WHY?†(Erikson, 1968)† Whereas Kolhberg’s stage result in â€Å"good interpersonal relationships† At this stage children–who are by now usually entering their teens–see morality as more than simple deals. They believe that people should live up to the expectations of the family and community and behave in â€Å"good† ways. Good behavior means having good motives and interpersonal feelings such as love, empathy, trust, and concern for others. Heinz, they typically argue, was right to steal the drug because â€Å"He was a good man for wanting to save her,† and â€Å"His intentions were good, that of saving the life of someone he loves.† Even if Heinz doesn’t love his wife, these subjects often say, he should steal the drug because â€Å"I don’t think any husband should sit back and watch his wife die† (Gibbs et al., 1983, pp. 36-42; Kohlberg, 1958b). These two stages are somewhat different in comparison. Erikson’s theory is basically demonstrates how a child mimics what he or she see by using inanimate objects. I believed every little girl played house with Barbie and little boys played cowboys and Indians. I loved to play in my doll house at the age of 4 and older. I also was starting to demonstrate what was right or wrong. Erikson’s fourth stage â€Å"School-Age Child (Competence) – Industry vs. Inferiority† â€Å"the Latency, we are capable of learning, creating and accomplishing numerous new skills and knowledge, thus developing a sense of industry (Erikson, 1968).† Kohlberg fourth stage is â€Å"Maintaining the Social Order reasoning works best in two-per son relationships with family members or close friends, where one can make a real effort to get to know the other’s feelings and needs and try to help (Crain, 1985, p 124).† These two stages exemplify several social skills. There are alike in detail. The age range from 6 to 12 is a very adequate age. I can recall being in the 4th and 5th grade and starting to have friends. I was a cheerleader and was learning that you have to be social in order to develop friendships. I was also taught by parents that little boys teased and picked on me because they liked you. I did not understand this but as I got older I slowly started to understand the concept of relationships. Next, the fifth stage of Erikson is â€Å"Identity vs. Role Confusion – Fidelity† â€Å". At this point, development now depends primarily upon what a person does. An adolescent must struggle to discover and find his or her own identity, while negotiating and struggling with social interactions and â€Å"fitting in†, and developing a sense of morality and right from wrong (Erikson, 1968)† Thus, Kohlberg’s fifth stage is â€Å"social contract and individual rights respondents basically believe that a good society is best conceived as a social contract into which people freely enter to work toward the benefit of all. They recognize that different social groups within a society will have different values, but they believe that all rational people would agree on two points. First they would all want certain basic rights, such as liberty and life, to be protected (Crain, 1985, p.125).† I feel that both of these stages are very similar. We want society to help us while giving back to society. It shows a sense of being part of something big. For example, I like the fact that I am able to vote. I believe that voting is a huge part of being part of society. It is important to know and feel that importance. The sixth stage of Erikson is â€Å"Intimacy and Solidarity vs. Isolation – Love† â€Å"the age is from 18-35, at the young adult stage, people tend to seek companions hip and love. Some also begin to â€Å"settle down† and start families, although seems to have been pushed back farther in recent years (Erikson, 1968).† Final stage of Kolhberg is â€Å"universal principles which believes that there must be a higher stage–stage 6–which defines the principles by which we achieve justice (Crain, 1985, p132).† These two stages are very different. Erikson is speaking about finding love which is considered your soul mate. Ages 18 through 35 is the common age that people start settling down and having children. I was 21 when I gave birth to my daughter. I tried to stay with her father which was 7 years older than me. He had not matured and did not want to step up to his responsibilities, even though he was much older than me. Kohlberg felt that stage 6 which resulted in the final decision of respecting each other’s beliefs. I find myself using an open mind and not judging anyone for their differences. I can relate to both of these stages. Erikson’s last two stages are â€Å"Middle-aged Adult: age ranges from 35 to 55 or 65 and the stage is Generativity vs. Self absorption or Stagnation which is defined as Care â€Å"Career and work are the most important things at this stage, along with family. Middle adulthood is also the time when people can take on greater responsibilities and control (Erikson, 1968).† Next, â€Å"Late Adult: age ranges from 55 or 65 to Death and the stage Integrity vs. Despair defined as wisdom As older adults, some can look back with a feeling of integrity — that is, contentment and fulfillment, having led a meaningful life and valuable contribution to society. Others may have a sense of despair during this stage, reflecting upon their experiences and failures( Erikson, 1968).† I am not at either stage of my life. I am very close to middle age. I actually consider myself to be a middle aged adult now. I am focused on furthering my career and supporting my family. I feel that this stage should be very important to both males and females. I have learned from working in the criminal justice field that this stage is not very important to males in society. There are more men in prison and jail than there are females. These men do not put the proper priorities in order to stay stable and have legitimate career. I am destine to reach far beyond 65 and live my life prosperous. In Closing, these two theorists had the same theories in mind. They described each stage of development differently. There concepts both compared and contrast with each other’s stages. I related to both theorists. I consider my life as a mirror of both Erikson’s and Kohlberg’s stages. Their phases exemplify positive and refined steps of everyone’s life. References Crain, W.C.

The war which the world feared upon never happened

The war which the world feared upon never happened, the Cold War. United States of America and the Soviets are preparing for this battle as who among these super powers will really dominate the world. As a means of preparation they are to dominate the seas, especially the under sea navigational fleet, the Submarines.American leaders as a means of preparing for battle put their trust and confidence in their submarine force. Empowered by their own power plants these nuclear submarines are to dominate the seas with unbelievable sophistication and with weapons of incredible destructive power.The idea of submarine came from the Germans who were the ones who pioneered in the creation of the vessel during World War II (Weir, 1998). The US Navy has envisioned that submarines of the future would go deeper and move much faster. Thus as the years passed, the nuclear submarine was created.Under the US military force, the main mission of the first known SSBNs or â€Å"Ship Submersible Ballistic Nuclear† was for the prevention of war to happen. They are to be deployed to strategic sites for them to guard and thus to prevent war   (Weir, 1998). Because of their relentless power, as the nuclear is used to propel them, they have the capability to submerge and circumnavigate the world with fewer expenses. They can submerge for number of days to avoid detection and can easily guard strategic sites as their main mission. They are considered as the guardians of a possible nuclear war.According to David Munns in his book, the greatest advantage so that submarines, armed with ballistic missiles, can release its relentless power is that they have to be close to the shore. This idea was the main basis for the development of the undersea military force of both United States and the Soviet Union. Throughout the 45-year Cold War both countries developed submarines, especially nuclear powered, to gain intelligence or for espionage, due to its stealth power, and to attack and destr oy any possible enemy surface ships. Its powerful ballistic missiles have the ability to attack ground or land based targets. Both countries develop such powerful undersea fleet and were considered as the most potent nuclear threat for both of them. (Munns, 2004)The main idea was that to counter this powerful surface warships and nuclear propelled missile cruisers and aircraft carries they have to develop more powerful underground fleet (Munns, 2004). With the development of the nuclear power, the first ship that was ever built by the Americans that went to sea is the USS Nautilus. It went to sea on January of 1955. It is propelled by pressurized-water nuclear reactor plant. This firs submarine built by the Americans sets the new standard for submarines (Huchtausen, 2002).The Russians on the other hand, built their first submarine which went to sea on a much later date. The K-3 or also known as Leninsky Komosol, it is a part of the November class of attack submarines only went to se a only on 1958. This submarine was the first Soviet sub who have reached the North pole, only in 1962, which the United States first sub USS Nautilus have already done four years earlier. The November class submrines however had serious problems one example was the accident happened in 1968 of its K-27 due to a radioactive gas lead which killed 9 people (Huchthausen, 2002).The next Class of submarines that was built by the Americans was the Skipjack Class Submarines. Built in 1959, this attack submarine was the first to combine nuclear power which has extraordinary speed. This is more hydronamic which has a new teardrop hull design. All other US submarines that was created was based on this design. The known accident that happened for this class of submarine was on May 21, 1968 when the USS Skipjack Scorpion was lost in the sea and was nowhere to be found even due to extensive military search. All the 99 people aboard the submarine also lost their lives (Compton-Hall, 1999).The Sovi et built the Hotel-class submarines on 1960. This is the first Soviet Nuclear subs which carries with it ballistic missiles. The design of the November Class is much similar to that of the November class, but with much larger compartment to accommodate the ballistic missiles (Compton-Hall, 1999). On the same year the Skipjack Class was created, the US Military built the USS George Washington Class. Built and deployed on 1959, this submarine was the first Nuclear Ballistic missile submarine which was created. The main idea for this ballistic missile submarines was that it would attack land-based targets with its nuclear weapons. They are to be deployed near shore targets so that their long range missiles can easily hit their targets.The Soviets then build the Victor Class submarines in 1967. Their design was to attack enemy submarines and to protect surface ships of the Soviets. The new teardrop hull enabled the Victor Class to attain higher speed. The Soviets however abandoned the c onstruction of the second Victor submarine design after learning through spy information that the NATO forces could easily track them (Compton-Hall, 1999). Due to this, the Soviets created the Victor III submarine.The Americans on 1961 built the Thresher Class attack submarines. This submarine is much stronger, much faster, and can dive much deeper. It is also designed to be quieter than the Skipjack Class, the materials used in this class have more streaming improvements. The name was however changed from Thresher Class to Permit Class when the submarine Thresher sank in New England in 1963 killing all 129 crew (Huchtausen, 2002).In 1967, the Soviets created the Yankee Class submarines. This is the first Submarine that has the same firepower as that of the US submarines. This is much quieter than the Hotel Class due to a new hull shape, a new propeller design, and exterior sound-deadening coatings which is much harder to track. Several modifications were also made on this class, wi th its big design it was enabled to carry miniature submarines.On 1976, the Americans built and deployed the Los Angeles class. This class had 62 vessels built and is considered as the world’s largest nuclear-propelled submarine. This class was designed to primarily protect carriers and other enemy submarine. The purpose of this submarine was the same as that of the Soviet’s Victor Class. This submarine however was much more powerful than the Victor class because of its capability to do other special missions such as deployment of Special Forces on the ground and attacking larger targets. The Los Angeles class was also improved for better ice operations on the North and South Pole (Compton-Hall, 1999).The next class built by the Soviet and one of the last Class is the Typhoon class submarine. During its time, in 1981, it was considered as the world’s largest attack submarine. This improved design which is much quieter compared to its size. This submarine is also more maneuverable even if it is huge. The design of this submarine is much more complicated due to the existence of two pressure hulls which is parallel with each other and a third hull which is on top of them. This design increases its width and had simplified internal arrangements. Being part of a cooperative arms reduction program of the former Soviet states, six of the Typhoon class was dismantled in 2003 (Compton-Hall, 1999).The Ohio-class submarine is the last among the long line of designs of the ballistic-missile submarine fleet of US.   It replaced the old 1960s version and was larger and more capable than its precedents.   These subs can carry more and longer-range weapons, operate more quietly, and dive deeper (Compton-Hall, 1999).   Russia, on the other hand, designed the contemporary of Ohio, the Oscar submarines.   These are Russia’s largest and most advanced and are still active submarines.   Designed to attack U.S. aircraft carrier battle groups, it carries three times as many antiship cruise missiles than its predecessors (Compton-Hall, 1999).Norman Polmar and K.J. Moore, were two naval officials under the US Armed Forces who were interviewed by Munns in his book. They said that â€Å"the United States and the Soviet Union put to sea a combined total of 936 submarines, of which 401 were nuclear propelled,† during the whole Cold war from 1945-1991 (Munns, 2004). The Soviet Union was the one who is aggressive in the development of submarines. This development still continues until after the 1970’s where research and effort to make the vessels more powerful were developed.From the mid-1940s until early 1990s, Cold War was a period of conflict and competition between two superpowers, the United States and the Soviet Union.   It was also a period of great technological advancements in the military with no less than the development of nuclear submarines.   Faster, quieter and deadlier weapons were developed. It wa s also this same period which placed the entire world on edge. And knowing the potentials of these weapons, the war that never happened also brought unparalleled relief to mankind.WORKS CITED:Compton-Hall, Richard. The Submarine Pioneers.

Tanks in World War I

In 1915 Europe was in the midst of World War I and was at a stalemate caused by trench warfare. There was a need for new and revolutionary weapons to end the dilemma. The British found a solution to this problem by inventing tanks. The invention of the tank had numerous pros and cons, but it ultimately changed warfare. Tanks were built for the purpose of traversing through trenches. Trenches were becoming a literal wall and prevented either side from advancing. Tanks were the solution to the predicament that was the Western Front. The first prototype was called Mark I and was tested for the British Army in the September of 1916. Tanks were progressive and enabled many new tactics. They used caterpillar tracks which had a less likelihood of becoming stuck due to sinking. Tanks offered protection against firearms and intimidated German infantry men that were shocked deeply by the fact that they cannot destroy a tank with machine gun alone. Tanks were also great for accompanying infantry to protect them. There were also cons that went along with the use of tanks. Tanks were very slow, moving at a rate of four miles per hour; casual human walking speed. They were mechanically unreliable, and broke down frequently. Most of the time tanks were hot, numbingly loud and generally uncomfortable for the crews. After the British introduced the tank into the war other countries had their own variations. France launched their first tank, the Schneider CA1, shortly after Britain had introduced the. Mark I. These tanks were the same as British tanks in most aspects, except for that they moved faster by 1 mph. Close to the end of World War I, Germany had their own tank. The A7V, nicknamed â€Å"The Moving Fortress† by the British because of the shape of the hull, was entered into war in 1918 and were in action for eight months. One hundred vehicles were ordered during the spring of 1918, but only 21 were delivered.

Definition of a Football Fan

Definition of a Football Fan 1st draft Football fans are by definition crazy. They behave insanely; they are insane about the past, and they are insanely loyal. If their team gives away something free, the fans rush to the stadium to get the hat or watever. Football fans just plain behave insanely. Baseball fans go similarly nuts when their favorite teams give away some attractive freebie. But football fans are even worse. Football fans freeze themselves in order to watch their favorite game. In addition, football fans decorate their houses with football-related items of every kind.When they go to a game, which they do as often as possible, the true football fans make themselves look ridiculous by decorating themselves in weird team-related ways. At the game, these fans do the â€Å"wave†more than they watch the game. Football fans love to talk about the past. They talk about William â€Å"Refrigerator† Perry’s 1985 Super Bowl touchdown as though it had happened last week. They still get all exicited about 1988’s â€Å"Fog Bowl†. They talk about John Elway’s final game as though it’s today’s news, though it happened in 1999.They think everyone should be as excited as they are about such old stories. Last of all, football fans are insanely loyal to the team of their choice. Football fans never wear their team T-shirts and warm-up jackets everywhere, even to work. Of course, if they have to dress up in business clothes, they can’t do that. Should their beloved team lose three in a row, their fans may begin to criticise their team. They still obsessively watch each game and read all the newspaper stories about it.This intense loyalty makes fans dangerous. To anyone who dares to say to a loyal fan that another team is better, or, God forbid, to anyone wandering near the home cheering section wearing the jacket of the opposite team, physical damage is a real possibility. Incidents of violence in football stadium have increased in recent years and are a matter of growing concern. Football fans really act as if they’er crazy. They behave insanely, they are crazy about the past, and they are too loyal. Final version What is a football fan?The word â€Å"fan† is an abbreviation of â€Å"fanatic†, meaning â€Å"an insane or crazy person†. In the case of football fans, the term is appropriate. They behave insanely, they are insane about the past, and they are insanely loyal. Football fans wear their officail team T-shirts and warm-up jackets to the mall, the supermarket, the classroom, and even—if the yon can get away with it—to work. If the team offers a giveaway item, the fans rush to the stadium to claim the hat or sports bag or water bottle that is being handed out that day.Baseball fans go similarly nuts when their favorite teams give away some attractive freebie. Football farns just plain behave insanely. Even the fact that fans spend the c oldest months of the year huddling on icy mental benches in places like Chicago proves it. In addition, football fans decorate their houses with football-related items of every kind. To them, team bumper stickers belong not only on car bumpers, but also on fireplace mantels and front doors. When they go to a game, which they do as often as possible, they also decorate their bodies.True football fans not only put on their team jackets and grab their pennants but also paint their heads to look like helmets or wear glow-in-the dark cheeseheads. At the game, these fans devote enormous energy to trying to get a â€Å"wave† going. Football fans are insanely fascinated by the past. They talk about William â€Å"Refrigerator† Perry’s 1985 Super Bowl touchdown as though it had happened last week. They describe the â€Å"Fog Bowl† as if dense fog blanketed yesterday’s game, not 1988’s playoff match between the philadelphia Eagles annd the Chicago Bear s.They excitedly discuss John Elway’s final gamebefore retiring. — when he won the 1999 Superbowl and received MVP honors— as if it were current news. And if you can’t mange to get excited about such ancient history, they look at you as though you were the insane one. Last of all, football fans are insanely loyal to the team of their choice, often dangerously so. Should their beloved team lose three in a row, fans may begin to react negatively as a way to hide their broken hearts.They still obbsessively watch each game and spend the entire day afterward reading and listening to the postgame commentary in newspapers, on TV sports segments, and on sports radio. Further, this intense loyaly makes fans dangerous. To anyone who dares to say to a loyal fan that another team has better players or coaches, or, God forbid, to anyone wandering near the home cheering section wearing the jacket of the opposite team, physical damage is a real possibility. Bloody noses , black wyes, and brooken bones are just some of the injuries inflicted on people cheering the wrong team hae fans are around. In 1997, one man suffered a concussion at a game in Philadelphia when Eagles fans beat him up for wearing a jacket with another team’s insignia. From February through August, footbalal fans act like any other human beings. They pay their taxes, take out the garbage, and complain aboput the high cast of living. But when September rolls around, the colors and radios go on, the record books come off the shelves, and the devotion returns. For the true football fan, another season of insanity has begun.

Presentation - Assignment Example From the time of financial crisis, American Banks increased their excess reserves in terms of cash funds held over and above the Federal Reserve requirement. Besides, Excess reserve increased from $1.9 billion in the year 2008 the month of August to $2.6 trillion in January 2015. Additionally, U.S banks are holding liquidity by pumping it into the economy through the Federal Reserve as excess reserves. Besides, instead of giving loans, implications lie in monetary policy and the real economy, elusive of current economic environment since its new and complex. Before the crisis in October 2008, costs and benefits of holding reserves went clear. The costs entailed benefits of guarding last minute outflows and foregone interest that requires immediate cash. Furthermore, depositor set aside money to cover emergency expenses, or investors hold reserves to enable them seize unforeseen opportunity (Craig and Koepke 1). Craig and Koepke suggest that the Simplicity of one to one correspondence between excess reserves and Federal Reserve balance sheet hides difficulty in predicting how banks behave in the presence of expanded reserves (1). Unfortunately, understanding this behavior is imperative deciding an appropriate policy that guards excess reserves

Criticism of a press release from Tourism Organization and relation of Essay

Criticism of a press release from Tourism Organization and relation of its content with theory - Essay Example Ban Kimoon emphasized the role that tourism can play in environmental sustainability and promotion of green growth as well as helping in the struggle to adapt to climate change. His speech was in relevance to the theme of the 2012 world tourism day that sought to emphasize the importance of sustainable energy to the tourism industry. As Ban Kimoon mentioned, the tourism industry stands in a capacity to contribute positively towards environmental sustainability. One of the indicators of the efforts made by the world tourism organization include the dedication of the 2012 world tourism day to addressing issues related to the value of adopting the use of renewable energy sources. Adoption of renewable energy sources by the tourism industry is an effort towards environmental sustainability. Since the industry’s activities involve a lot of transportation and washing. Transport involves both the aircrafts and vehicles. Adoption of energy sources that have minimal carbon emissions is one of the advances the tourism industry is making. Using such fuels minimizes air pollution as well as preventing ozone effects that have resulted to adverse climate changes (International Conference on Sustainable Tourism, Pineda, and Brebbia, 2010). In addition, the industry has a new invention of an online tool-kit that helps hoteliers get a reflection of their total energy consumption rates. In addition, the tool-kit offers the hoteliers strategies of saving energy. Moreover, hoteliers can use this kit in exploring the possible ways of adopting renewable energy sources. The launching of the kit intended to improve energy efficiency in most of the tourism facilities and increase their ventures in renewable energy. The kit bears the name ‘Hotel Energy Solutions’ and hoteliers have a free access to the kit online. This is a positive move towards environmental sustainability. The long-term effects of the use of the

Miranda Warnings Essay Example | Topics and Well Written Essays - 750 words

Miranda Warnings - Essay Example (Means 2007:73) If this warning would have been read at the scene, you would have realized that the boy could not speak English. You still could have taken the boy into custody, but refrain from asking questions. If you recognized the language, a radio transmission to downtown would have allowed for a translator to be on hand upon your arrival. This suspect must voluntarily waive their Miranda rights before questioning can proceed and understand them (Miranda v. Arizona). The ability to voluntarily waive Miranda rights orally and in writing must be done with understanding. If a person does not understand their right to an attorney without charge, that violates their Miranda rights. Even if they are not confessing or talking, the person needs to understand their right to an attorney due to the third Miranda right. Thus before this suspect, which you state was arrested, can be booked they must be read their rights. If the boy is underage, which was not established due to the language, a good faith effort to find a parent or guardian must take place. When the family member arrives at the police station, an effort to find the parent or guardian must be completed. The family relative can provide the age of the defendant. Even if the boy is underage, the Miranda rights must be given and understood. Ferdico, Fradella, and Totten (2008:724) reports that a suspect must understand and waive their rights. The guardian/relative and boy must understand that a lawyer will be provided for free. The third Miranda right give suspects the right to a lawyer even if poor. The reason a parent/guardian of a suspect needs to know this right is to protect the suspect. If a parent/guardian thinks that they will have to pay for an attorney, they might counsel the boy to talk to avoid paying for counsel. That could be ammunition for a good defense attorney. The boy must understand that an attorney will not burden his family. That is his third
