How certain characteristics are transmitted from one generation to another

How certain characteristics are transmitted from one generation to another Rules of Mendelian Genetics Mendels Law is the study about how a certain characteristics are transmitted from one generation to another in an organism. This study was derived from an Austrian monk, Gregor Mendel (1822 C 1884) who is considered as the father of genetics. He believed that natural laws such as those that govern inheritance could be explained as mathematical relationships. In his experiments, Mendel used ordinary pea plants to study the traits, he pair these pea plants with considering the control over each reproduction to prevent the pea plant from self fertilizing. The traits that are being observed are the colour of a plants flower, the location on the plant, the shape and colour of the pea pods, the shape and colour of the seeds and the length of the plant stems. Pea plants are used because they are easily available and can be manipulated in large amount within a short period of time. (Starr, Evers Starr, 2010) Mendels approach for his experiment was to transfer pollen from the stamen (which is the male reproductive organ that contains male sex cells) and to the pistil (the female sex cell which contain female reproductive organs) of another pea plant. In the first experiment, he took two pea plants with true breeding variant; one with round seed and another with wrinkled seed. The offspring that were produced in the first generation (F1 generation) had all round seeds. This shows that the pea plant will only take the dominant trait that is the round seeds. Next, Mendel crossed two of the F1 generation plant together, he obtained a result of 75% of the plant is round seeds whereas 25% of the pea plants are wrinkled seeds. Based on this result, a ratio of approximately 3:1 will be deduced for the traits in F2 generation. As a result of these experiments, Mendel was able to state three generalizations about the way characteristics are transmitted from one generation to the next in pea plants. (Science Clarified, 2010). From this pea plants experiment, Mendel derived 3 theories that support on genetic inheritance ? Mendels first principle of genetics, the law of segregation states that the sex cell of a plant or animal may contain one factor (allele) for different traits but not both factors needed to express the traits. Each offspring, however, would only display the characteristics of one parent and not a blend of the two different characteristics of the parents. ? Mendels second principle of genetics, the law of independent assortment states that characteristics are inherited independently from other characteristics. Any trait in a generation is independent of other traits if the parents of the generation have two or more traits that vary from each other. ? Mendels third principle, principle of dominance states that each inherited characteristic is determined by two heredity genes, one from each parent which determines whether a gene will be dominant or recessive. This means that the trait of one parent must be dominant over the trait of the other parent, and so the dominant trait would be displayed by the offspring. (Minnesota State University, 2010; Nigel, D. P.,2006 ). Introduction to traits of family There have been variations in different characteristic in my family genes. The variations of the genes are mainly caused by inheritance from my parents who carry a genotype of certain traits; this trait is passed on from one generation to another. The dominant allele of the traits of the genotype would be the phenotype of the offspring. I have chosen to look into the appearance of one-sided dimples and blood types in my family genes. Cheek dimples occur when the muscles underneath the surface of the skin are shorter than the skin on top, so when you smile, the muscle pulls the skin at its attachment point, thus folding the top skin as it is pulled back. Chin dimples are actually a cleft chin in which the bones do not fuse completely and the outer skin lies on top of the cleft bone, revealing the structure underneath. In most cases, facial dimples appear on the cheeks, and they are typically not visible until someone smiles. However, some people only have a dimple on one side; this physical trait can actually be rather endearing (Smith, S. E., 2010). The look of dimples can also vary; as an inherited trait, unusual dimples can be passed on through multiple generations of a family. Dimples occurrence can be relatively related to genetic inheritance, dimples are dominant trait that will be pass on from the parents (K-show, 2008). If you inherit the genes for dimples, there may be other factors during your developmen t that could lengthen the muscles, or allow full closure of the cleft chin. Next, all humans can be typed for the ABO blood group. There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individuals type in most cases (Dennis ONeil, 2010). Every individual inherits one blood type allele from each their biological mother and their biological father. Based on the alleles of a person, the blood group genotype of the person can be determined. The O allele is the recessive allele amongst the blood group alleles. A person with blood group A can have either IA IA or IA IO as their genotype. Type B blood is produced when an individual has either genotype IB IB or IB IO. Genotype IO IO results in type O blood while type AB blood results from genotype IA IB (Windelspecht, 2007). Analysis Based on the phenotype occurrence in my family, I have come out with a research based on the traits on genotypes in my family. In this research, Ive taken consideration of the variation in traits from my parents and siblings; my brother and sister. One-sided dimples In my family, my father carries the gene of one-sided dimple, my mother do not contain dimple, my sister contains one-sided dimple and my brother and me do not contain dimple. Based on the data I had collected, a pedigree chart is drawn to illustrate the traits in my family. Figure 1 : pedigree chart on one-sided dimple of my family Since one-sided dimple is considered to be an autosomal dominant traits. From this pedigree chart illustrated above, my father have a phenotype of one-sided dimples, he would be either be carrying a homozygous dominant (DD) or heterozygous dominant (Dd) genotypes. On the other hand, my mother would be carrying the homozygous recessive (dd) genotype. My sister also carries the one-sided dimple trait; therefore she also be either having the genotype of DD or Dd. My brother and I do not have dimples, therefore why we would have carried the dd trait. Since, allele of our genes cant be seen; therefore we could only predict which of the possibility outcome the genotype of each individual belongs to. Based on the different possible allele, I have built a Punnets square to list out all the possibility outcomes of the genotypes outcome of the offspring from my parents depending on which genotype my parent possesses. D d d Dd dd d Dd dd D D d Dd Dd d Dd Dd ( ii ) ( i ) ( ii ) Figure 2 : Punnet square based on parents genotype? Based on the Punnet square ( i ), the possibility of homozygous dominant allele is being used. From this point of view, the outcome of a mixture of DD and dd would result in a Dd gamete. Therefore, based on the result, the offspring produced would be heterozygous dominant (Dd). The probability of the offspring produce by my parents to be heterozygous dominant would takes up 100%, this means that there would not be any possibilities of any offspring not having one-sided dimples. In addition, no offspring would also me homozygous dominant to one-sided dimples. On the other hand, in Punnet square ( ii ), heterozygous dominant (Dd) allele is being used, the possibility outcome of allele from the combination of Dd and dd would result in a Dd or dd offspring. The probability of a heterozygous dominant (Dd) gamete would be 50%, whereas the probability of the homozygous recessive (dd) gamete would also be 50%. There would not be any homozygous dominant offspring with one-sided dimple being produced. After analysing both the Punnet square, I came to conclusion that that my family follows the genotype of Punnet square ( ii ). This is because in my family, among the siblings, we have a variation between having one-sided dimples and not having dimples. Therefore, from the possibility of Punnet square ( i ), all the offspring would have dimples. Nevertheless, in my family, my brother and I do not have dimples whereas my sister have one-sided dimple. So, it can be said that the possibilities in Punnet square ( ii ) would be much more accurate. It shows that there are variations between gametes which have and have not got one-sided dimples. This could clearly explains why the occurrence of one-sided dimples only on my sister. Blood type A blood test had been carried out to determine our blood type in my family. From the result, it is shown that my father is tested to be blood group O, my mother is tested to be blood group A, my brother is tested to be blood group O, my sister is tested to be blood group A and lastly I am tested to be blood group O. Based on the data I had collected, a pedigree chart is drawn to illustrate the traits in my family. Figure 3 : Pedigree chart of blood group in my family From the pedigree chart, my father has blood group O, the possible genotypes for his allele would be IoIo. This would also apply to my brother and I, we both also contain the possible genotype allele of IoIo. On the other hand, my mother has blood group A, the possible genotypes for her allele would be IAIA or IAIO. My sister also has blood group A, she would also have the possible genotypes for her allele is IAIA or IAIO. By sorting out the possible genotypes in the allele, the data will be analysed into a Punnet table for a clearer outlook on all the possibilities from the combination of both the genotypes from my parents. The Punnet square will show the different combination that will result in a variation of offspring. IO IO IA IOIA IOIA IO IOIO IOIO IO IO IA IOIA IOIA IA IOIA IOIA ( i ) ( ii ) Figure 4 : Punnet square based on parents genotype Based on the Punnet square ( i ), the genotypes of my fathers allele is IOIO , whereas my mothers possible genotype is stated as IAIA . The outcome of this mixture results in the possibility of an offspring with only IOIA, which is blood group A. The probability of the offspring becoming a blood group A would then be 100%. None of them would be of blood group O. In Punnet square ( ii ) the genotype of my fathers allele is IOIO, whereas my mothers possible genotype is IAIO . The possible genotypes of the offspring produced by this combination of alleles will be genotype IOIO and genotype IAIO. The offspring could have a variation of blood type O or blood type A. The possibility of getting blood type O is 50% and the possibility of getting blood type A is also 50%. After analysing both the Punnet square, I can conclude that my family follow the genotypes as stated in Punnet square ( ii ). This is because in my family, among the siblings, we have a variation between blood group A and blood group B. Therefore, from the possibility of Punnet square ( i ), all the offspring would result in having blood group O. Nevertheless, in my family, my sister has blood group A whereas my brother and I have blood group O. So, it can be said that the possibilities in Punnet square ( ii ) would be much more accurate. It shows that there are variations between gametes which have the different group type. This could clearly explain why the occurrence in variance of different blood type within different people. ? Conclusion The study of Mendels Law leads us to enhance more on our genetic inheritance. Knowing our inheritance may help us to study a large range of different traits; like hair colour, iris colour, dimples, and eyes. We will be able to notify and recognize the different genetic variation, which will also help in preventing certain disorder from spreading through reproduction. A few of the disorder that are genetically inheritance are like Downs syndrome, Turner syndrome, sickle-cell anemia, colour blindness and haemophilia. Prevention towards this kind of disorder will widely safe many misfortune life of infants. Mendels Law do not only emphasis on human trait, it is used in many agricultural field to improve the production of crops. The seeds of the corn plant is modified and paired genetically to improve its taste, colour, quantity and quality. These seed are being paired to obtain better traits from different types of fruits. The seasonal fruits can be planted all year round now, the fruits are mostly seedless; all these are from the discovery of genetic inheritance. Not only that, Mendels law had also helped me in this research regarding the genotype of different traits in my family. For one-sided dimples, Ive found out from the Punnet square that, my father is heterozygous dominant pairing with my mum with homozygous recessive that will result in a mixture of heterozygous dominant and homozygous recessive offspring. For the blood type, Ive found that my father is is IOIO, whereas my mothers possible genotype is IAIO. In conclusion, Mendels law can be used to illustrate inheritance traits; the Punnets square can help us visualize all the genotype of the traits. This enables us to learn our genotypes based on our phenotypes shown, that is the one-sided dimple and blood type. It is important for us to study and understand our patterns of inheritance.

Tim Burton Style Analysis

Tim Burton Style Analysis Tim Burton has achieved much fame for his imaginative movies and his quirky remakes of old classics such as Alice, Batman, and Charlie and the Chocolate Factory. It is in Edward Scissorhands though, a heartfelt story about an outsider looking in, that Burton shows off his true skills as a director. Using point of view, setting, and motifs his film becomes not just a good movie, but an amazing classic. Burton uses point of view to show the characters perspective and to fill in the missing gaps in the characters history in the form of flashbacks.For example, one of the beginning scenes in the movie show that the devout woman looks out the window and sees the other woman of the neighborhood flocking together, yet not inviting her to join them. It shows that the woman is an outcast, and is not included in things. Another scene shows Edward’s dejected face and then flashes over to a scene of Kim goofing off with her boyfriend. It lets the viewer understand that Edward is interested romantically in Kim, and thus upset that she is involved with someone else. This is a more subtle technique, and makes the scene more memorable to the viewer because they didn’t come right out and say it.As opposed to telling the audience about something, Burton prefers to let them see for themselves. To show Edwards origins, Burton has Edward looking out the window and has a flashback about how he was created. Burton also uses setting to a magical extent. Burton is an admirer of over-exaggeration, and this is evident in his distinction of the neighborhood and Edwards’s castle. Whereas the community is bright a cheery, with houses of alternating color and rather small proportions, the castle is dark and opposing. All the houses in the community don’t have more than four feet between them, and even the backyards are visible from the street.Burton also exaggerates the looming castle’s isolation by putting it on a mountain. Burton purposefully designs the community to be the homey, picturesque American dream while Edward’s castle is the definition of gloom and doom. Yet when Peg first comes to the entrance of the castle, she encounters an amazing garden, much more beautiful than anything thing the people in the community could make, showing us that our perceptions aren’t always right. Burton often uses motifs in his movies and Edward Scissorhands is no different. Among many, one of the motifs Burton uses is conformity vs. ndividuality. Burton’s movies all carry common threads, and like all of Burton’s previous main characters, Edward is an outcast. He is a spark of creativity in an otherwise dull society. The citizens of the community choose to conform and the all have flat personalities. One is either a maneater or a motherly type or some other cliche, and that part seems to encompass the rest of their personality. While Edward, who is so different from the way he looks to the way he acts, seems to be the only human character. His personality possesses many layers.The citizens also dress bright and cheery is a retro-style, while Edward with his uncontrollable hair and pale skin looks like a gritty Goth. In conclusion, Burton’s skill shines throughout the entire movie. Using point of view, setting, motifs, and other style techniques, Burton makes Edward Scissorhands a true hit. Tim Burton’s unorthodox style gives new standards to the movie business, and delivers heartwarming stories about misconceptions and finding yourself. With Tim Burton’s masterful skill and playful humor, it becomes obvious why Edward Scissorhands is such a hit. Gigi Orphali 12-8-11 p. 5-6

Political Psychology Essay

Rape victims, survivors of plane crashes, combat veterans, and others who have experienced extremely traumatic events may react emotionally with a posttraumatic stress disorder. This reaction is characterized by involuntary reexperiencing of the traumatic events, especially the original feelings of shock, horror, and fear, in dreams or flashbacks. In addition, victims experience an emotional numbing in relation to everyday events, associated with feelings of alienation from other people. Finally, the emotional pain of this reaction can result in an increase of various symptoms, such as sleep problems, guilt about surviving, difficulty in concentrating, and an exaggerated startle response (Calkins, 1996). The Situation: 9/11   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   A more recent example was the 9/11 incident. The safety and protection that was a seal of American social order was devastated by the 9/11 aftermath. The American people who have gone through the bereavement of either of their parents, brothers, sisters, next of kin, or friends may well be putting up now with overpowering anguish. They will want all the emotional assistance they can obtain and they will need an extended recovery period. Life will never look the same again for any oblivious or sentient American people, but the young people who have upheld personal fatalities may need considerable support from qualified, compassionate specialists (Skene, 2001).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The world is not in the slightest peaceful, but at present, there is no security issue taking center stage and the situation in the 9/11 assault is no exception. The 9/11 event had impressed upon America a greater sense of threat at the advent of the new millennium. The 9/11 terrorist attacks incited terror, fury, grief, revulsion, fear, empathy, bewilderment, melancholy, retribution – sundry reactions in a nation that was everlastingly changed. To translate the mixed reaction of a private individual in a more politically relevant sense, it is wise to recall how then Senator Edward Livingston could be more important at these times with his words in a debate on the Alien and Sedition Acts: â€Å"†¦we are absurd enough to call ourselves free and enlightened while we advocate principles that would have disgraced the age of Gothic barbarity† (Skene, 2001).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   They may well not entirely come to terms with the intangible theories thrashed out by counselors or on the television newscast but are prone to be directed in their thoughts by a distinct discernment of validity. They may have dealings with a diversity of sentiments and impressions, and their articulation may subsume mimicking or self-deleterious actions as a way of dealing with their retaliation, fury, and despondency. A number of children at this phase may demonstrate a reluctance to speak of their sentiments and thoughts (Dunn, 2001). The Psychology of Situation: Posttraumatic Stress Disorder   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The emotional responses of posttraumatic stress can occur immediately following the disaster in an acute form and subside over a period of several months or can persist, becoming a chronic syndrome often called the residual stress pattern. In other cases, people may show no immediate reaction but may experience a full-blown posttraumatic stress disorder after a delay of months or even years. Clinicians are still discovering veterans of World War II and the Korean War who are displaying residual or delayed posttraumatic stress disorders (Hinkle, 2004).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This delayed posttraumatic stress syndrome has been a special problem in the case of Vietnam veterans. The problems of many seemed to be made worse by feelings that they had been rejected by an unsympathetic American public and that they had been betrayed by their government and had spent important years of their lives in a wasted effort (Bornstein, 1994). In a study of Vietnam veterans with combat experience, called the â€Å"Forgotten Warrior Project,† John Wilson, a psychologist at Cleveland State University found that (Kagan, 2004): Their suicide rate was 23 to 33 percent higher than the national average. Of those who had been married when they left the United States, 38 percent were divorced within six months after returning. The rate of hospitalization for alcoholism or drinking problems was high and increasing. About half of them still had some emotional problems related to adjustment of civilian life. Brian Seaward is one of the authors that delved into the realm of stress and its health consequences. Seaward notes that aside from the special life events that may be experienced by almost everyone, the most appreciable part of the list is the concept of change.   This implies that change may be in tandem with stress as being a natural part of modern-day living.   That change is the ultimate source of stress.   â€Å"Change becomes a powerful stressor agent because it necessitates adaptation whether it is perceived as a negative or positive experience† (Calkins, 1996). The important features of posttraumatic stress disorder, according to Seaward, are cognition and stress.   Stress affects cognition as anxiety intrudes on one’s consciousness as demonstrated by his unstoppable pangs of emotion, excessive preoccupation with the threatening situation or person, startling reactions, and other unwanted sensations.   It may also impair memory and attention during cognitive tasks.   It may also enhance attention, principally regarding memories of the stressor but repetitive thoughts can perpetuate stress and make it chronic (Calkins, 1996). Seaward also enumerates the emotional signs of health hassle, which are among others, anxiety, irritability, increased aggression, lack of enthusiasm, depression, alienation, and low self-esteem. Indecision, impaired judgments, lack of concentration, lapses in memory, and absentmindedness are some cases of mental drawbacks caused by health troubles. Seaward also shows that there are individuals who are more prone to health troubles than others.   As a result, the ability to cope with poor health is not the same with everyone. For instance, effective coping with stress depends upon how people go about their day-to-day lives. Lifestyle is a key factor in determining the likelihood of an improved posttraumatic stress disorder (Calkins, 1996). Posttraumatic stress disorder is usually coupled with feelings of sadness, discouragement, and dissatisfaction and usually occurs with other symptoms, such as feelings of worthlessness or guilt, decreased energy, and suicidal thoughts. Just as one can have the flu and bladder infection at the same time, it is quite possible, especially in the milder forms of bipolar disorder, to be both abnormally depressed and anxious at the same time (Dunn, 2001). Survivors of extremely traumatic experiences such as 9/11 are sometimes left with special anxiety problems. Some act as if they have been by the shock of their ordeal. Their interest in life is diminished, and they feel alienated from the people around them. Others develop a tendency to remain constantly on the alert, as if disaster is sure to strike again at any moment. They tend also to startle easily. People who have lived through auto crashes may panic at the sound if cars in the night. Those who have endured a mugging or rape may respond with a start whenever they hear strange sounds, and some former prisoners o war and hostages report similar reactions whenever they hear approaching footsteps (Skene, 2001). Survivors of psychological trauma are likely also to keep reliving their experience. They suffer from nightmares in which the shattering episode is reenacted in all its terrifying detail, and by day they find themselves suddenly overwhelmed by harrowing memories whenever they are exposed to situations that even remotely resemble the original event (Garcà ­a, 2005). There is evidence also that mood disorders are related to disturbances in the brain, to such an extent that the symptoms sometimes appear without any provocation. Neither the depressed individual nor the close family and friends can point to any unusually stressful event that might have caused a depression (Dunn, 2001). The Responsive Behavior of the Young and the Old Posttraumatic stress reactions can occur at any age.   Some people get over the traumatic experience of 9/11 soon enough, but others are troubled by symptoms for years on end. A number of elderly concentration camp survivors broke down completely decades after their ordeal was over when they had to be hospitalized for medical reasons. The experience was sufficiently similar to imprisonment to reopen fully the old psychological wounds (Garcà ­a, 2005). Children endure with bereavement a lot in the vein of adults, but with still not as much of discernment (Garcà ­a, 2005). When taking children in hand, it is imperative to recognize that they almost certainly discern more than what parents grant them credit for. Despite the fact that parents inherently desire to safeguard their children from pain, even the youngest kid understands that something is dreadfully wrong and yearns to grasp why the every adult distraught and in tears. This protective attitude merely serves to deprive the child of a chance to learn more about grief management and coping skills, which are indispensable throughout a person’s life, especially when he or she continues live in the absence of any parent who is supposed to shield them from deep sorrow since it is the parent or any close relative who has passed away (Garcà ­a, 2005). It is essential to acknowledge that every child is inimitable in his or her comprehension of the entire process of death. This discernment hinge on their developmental phase, intellectual skills, teachings by parents, teachers, and significant others, personality attributes, imagery in the media, spiritual convictions, and prior incidents of death induced by 9/11 (Hinkle, 2004). Nevertheless, there are a number of consequential factors that will be useful in comprehending how young people live through and cope with death and its aftermath (Dunn, 2001). Coping strategy of an individual’s behavioral and psychological efforts to buffer or minimize environmental and internal demands of posttraumatic stress disorder. Coping means that the person is â€Å"taking charge of his or her own life and is seeking the resources needed to solve current problems† (Garcà ­a, 2005). Seaward furthers that although the coping strategies used by individuals are often distinct, coping temperaments are to a large extent acquired from the social environment. The manner in which people attempt to resolve stressful situations, the cognitive strategies that they use to downsize threat, and the techniques for handling tensions are largely gained from the groups to which they belong.   A person tries to contain the threat and beat stress in two ways, namely focusing on the problem and on the emotions (Bornstein, 1994).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Other grown-ups are overly wrapped up in their anguish to make an effort to comprehend how the firsthand witnesses of the 9/11 attacks fathom. Other people usually misconstrue the bystander’s demonstration of sentiments, characteristically hold themselves responsible for their fellowmen’s lamentation or rage. Therefore, even though it is likely for the entire people to express their sorrow in the presence of the world, it is essential to impart an elucidation to the terrorist that they can face the future more stalwartly. Discovering how to communicate their anguish, resentment, and apprehension will help Americans to contend with comparable disasters if truly inevitable in the future (Skene, 2001). Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   No question about it; the 9/11 incident was the commencement of enlarged hostilities and vigilance as well. The imagery being broadcast was far too excruciating to behold. Mass terrorism is not a regular crime; it is an enormously terrible crime. Tens of thousands, more or less, are the terrorists’ target to inflict fatality or fear upon, and they are more than determined to rule the world. With continued weak will, no wonder how more people would struggle to stay untreated with posttraumatic stress disorder (Skene, 2001). Attitudes toward those with posttraumatic stress disorder have improved over time. Today, individuals with PTSD are fortunate enough to be treated in hospitals and clinics instead of being out away in prisons or asylums. But they are still far from universally accepted either within the family or community. How they are viewed by others can be critical. It can help determine whether they will recover sufficiently to function in society, or to continue to be overwhelmed by their symptoms and even get worse (Calkins, 1996). For a person with posttraumatic stress disorder, there is no clear-cut organic problem, no violation of basic social norms, and no loss of orientation to reality, but the individual shows a lifelong pattern of self-defeating and inadequate coping strategies aimed more at reducing anxiety than at solving life problems. By mental aberrations or psychological scars, the PTSD patient proves to others that he or she is impotent in the face of a threatening world (Dunn, 2001). Our growing understanding of posttraumatic stress disorder does more than enable society to reclaim its familiar stranger. In making sense of posttraumatic stress disorder, we are forced to come to grips with basic conceptions of normality, reality, and social values. And mind loosed from its stable moorings does not just go on its solitary way; it bumps into other minds, sometimes changing their stability (Kagan, 2004). Many PSTD patients are privately treated at home, while others have learned to conceal their disturbances and not act crazy in public. Still others act out their mental problems in ways that society does not judge as mentally disordered; perhaps joining the hate groups, or engaging in socially acceptable forms of violence. Just as unemployment statistics do not include all those who are chronically unemployed and have stopped looking for work, so, too, statistics on posttraumatic stress disorder omit those who suffer in silence, living a marginal existence on the fringes of society (Hinkle, 2004). Indeed, victims of posttraumatic stress disorder caused by 9/11 are usually beset by extremely difficult psychological and social problems. They are likely to be financially strapped, not only because the therapy can be expensive, but also it interferes with productive work. They tend to be outcasts from both the family and society at large. Often the only persons willing to give them serious attention are their fellow PTSD patients, which do not really help as negativity enlarges (Bornstein, 1994). Under such depressive, circumstance, they need considerable help to break free from prejudiced society and get a fresh start in life. References Calkins, Mary Whiton. (1996).

D Caries essays

D Caries essays Caries have been a constant nuisance to humans, decaying teeth can become a major problem for those affected. It is certainly not the oldest pathology, nor the one of the greatest prevalence throughout humankind, but the information that can be extrapolate from such pathologies is great. The aim of this paper is to outline the pathology of caries and the influence that these have had on the human populations affected. Caries or caries dentium is the common name for tooth decay. It is a local disease, which is characterized by an irreversible and permanent destruction of the tooth hard tissue, enamel. Thus spreads the destruction to the rest of the tooth and, and possibly leading to tooth loss and possibly infections in other areas, more specifically through the maxillary or mandibular areas. Also I have included some other defects that are import and not only to the observation of caries but overall pathologies and their implications for the individuals affected. In this paper I will attempt to outline the causes of this disease and some of the numerous factors that cause it, as many have a hand in the process. Also I will show how these changes were brought about and how these affected the individuals with caries. To begin I will introduce the reader he to other defects that affect the same area and should be considered when any analysis of the area is to be understood. Any disturbance, such as severe infection can disrupt enamel formation. That disruption of enamel formation will leave an enduring record as a disorientation of enamel prisms. Because the human dental growth sequence is known, the age at which the enamel disturbance occurred can be determined from the location of the disturbance within the enamel. A standard chart for dental development can be consulted for this purpose. There is extensive literature (now in excess of 500 articles) on the epidemiology and etiology of enamel defects. Many of which have been...

Chapter 3 Product and Service Design 2 Essays

Chapter 3 Product and Service Design 2 Essays Chapter 3 Product and Service Design 2 Essays Chapter 3 Product and Service Design Product Design The product-design process consists of designing products that perform required functions and satisfy customer requirements. The product-design process is highly developed because it is the focus of mechanical (and civil, aeronautical, and automotive) engineering. Most product designers hold degrees in mechanical engineering unless they are designing public infrastructure (civil engineering), automobiles (automotive engineering), or aircraft (aeronautical engineering). These engineering fields provide the theories that are applied in designing new products. There are also numerous computer-aided technologies available to aid the product-design process. The tools used in the product-design process include function analysis (also known as value engineering), computer-aided design (CAD), computer-aided engineering (CAE), computer-aided process planning (CAPP), computer-aided manufacturing (CAM), and quality function deployment (QFD). Function Analysis In function analysis, the functions performed by products are expressed using a two-word verbal model consisting of a verb and a noun. For example, modern toasters use infrared radiation to toast bread. The most common way to create infrared radiation is to apply power to nichrome wire wrapped back and forth across a mica sheet. Thus, functions performed by a toaster include: â€Å"toast bread,† â€Å"create radiation,† and â€Å"power nichrome.† The many functions performed by a product are organized using a function diagram. Moving from left to right, the functions explain how higher-level functions are performed. Moving from right to left, the functions explain why lower-level functions are performed: Function Diagram How? - -Why? Toast bread -Create radiation-Power nichrome Mechanical engineers (among others) are taught how to design products to perform required functions. Hence, the product-design process might begin by giving the designer the functions the product must perform. Function analysis can also be used as a means of fostering creativity and innovation. This is done by identifying the functions performed by an existing product and perhaps organizing some or all of them into a function diagram. The designer is then given only the functions (or function diagram) and is told to design a product that performs these functions. By abstracting the physical product using function analysis, the designer is freed to come up with entirely new ways of performing the required functions. Conversely, if a designer is given the existing physical product (such as a toaster), and told to design a new toaster, the result is likely to be only an incremental improvement. Function analysis was particularly popular during World War II when it was known as value engineering. Material shortages were commonplace during the war because most of the nation’s resources were dedicated to the war effort. Consequently, engineers used value engineering to reduce product costs and resource requirements. The engineering or design problem was to perform required functions using less resources, and particularly fewer resources that were in short supply. Once World War II ended, and the material shortages were relieved, value engineering fell out of use. Its real benefit today is providing a very clever means of fostering design creativity and innovation. CAD, CAE, CAPP, CAM, and Rapid Prototyping Computer integrated manufacturing consists of computer-aided design (CAD), computer-aided engineering (CAE), rapid prototyping, computer-aided process planning (CAPP), and computer-aided manufacturing (CAM). Computer-aided design (CAD) is a three-dimensional computer drawing program used to draw new products. The product is drawn in three

The involvement allows the various departments to participate, leading to optimal decisions that benefit the organization. This method poses a threat of death on a supplier who fails to deliver the required consignment. Given that no one would want to die, a supplier had to ensure that the goods were delivered on time. Consequently, the method led to the constant and prompt delivery of goods, thus enhancing operations in Sweden. On the other hand, the crude method caused suppliers to fear for their lives, which does not promote good relations in business. Non-performance in modern day can be handled in ways that are more sophisticated. Examples include the cancellation of supplier contracts, and awarding them to other suppliers who can manage to deliver. The skill of negotiation serves a critical role in the field of purchasing. It allows the buyer to bargain for a favorable and lower price, compared to the price being offered by the seller. Therefore, negotiation enables organizations to acquire quality products at considerable prices, which help in reducing costs. Communication also plays a critical role in procurement. It ensures that orders are placed in the right way, and in the right quantities. The skill, further, allows the company to trace the goods, thus ensuring their timely delivery. This leads to customer satisfaction as they acquire goods when and where there need them, without inconveniences. Computer proficiency promotes the ability of an organization to compete successfully in the market, through adoption of technologies that promote the efficiency of an organization. Technological advancements allow a public organization to improve the efficiency of procurement by reducing the costs associated with the process. E-procurement, for example, leads to the employment of a few employees, thus saving on expenses. More to

Machiavelli's and Plato's political thoughts Essay

Machiavelli's and Plato's political thoughts - Essay Example But what does the science of running the state imply? Lots of people ruminated about this question. Plato started from the fact that there is an ideal state, a perfect specimen, and its multiple repetitions are simple distortion in the real world of things. In Plato's view, expressed in his treatise â€Å"The Republic†, the main basis of any ideal state is justice. Plato argues that every citizen is given a special class, the most suitable to his or her nature, i.e. justice is correspondence of a real thing with its idea; the state is ideal, when each citizen acts in accord with his own essence. Since there are individual differences between people, Plato proposes the division of society into several estates: the philosophers - the rulers, warriors – the guardians and craftsmen – manufacturers (Pangle, 1980). The ideal system is when every citizen’s interests are identical with the public ones, when personality does not claim for individual self-worth and complete autonomy in actions. Plato’s state and civil society are represented in a single, homogenous, holistic, undifferentiated concept. Plato points out the following forms of government: the royal regime (monarchy), the aristocracy, timocracy, oligarchy, democracy and tyranny. The most right and reasonable, he believes, is aristocracy. Other forms of government are consistent deviations from the ideal state. Aristocracy is a rule of the best, approved by the people. The person, who is reputed to be brave and wise, should have power and rule the state. The basis of this form of government is equality by birth. In Plato's view, a real governor should not seek for power; he is not willing to rule the country and corrects the vices of other people (Kochin, 2002). People, guided by ambition, fame and money are not suitable for this role. The dialogue "Laws" is the last work of Plato. Estate division of citizens is replaced with gradation of property qualification. Along with t he recognition of slavery Plato demonstrates his disdainful attitude towards productive work. Ideal state structure, by Plato, is combining of democracy and monarchy (Pangle, 1980). The thinker of the Renaissance Niccolo Machiavelli expressed his own opinion on state structure and described an ideal state governor. In modern history, Machiavelli was the first thinker, who began talking about the economy of the state as an integral part of its prosperity. Summing up the historical experience, Machiavelli observes that those rulers, who sought to be generous, spent all their wealth and savings on support the glory of generous rulers. Thus, generosity ruins sovereign’s authority and country, causes the resentment of many. Thus, Machiavelli was accused of cruelty. However, such accusations are groundless. After all, Machiavelli never wrote that a good ruler should always apply fierce measures. On the contrary, he warned that the new sovereign should not be gullible, suspicious an d quick to slaughter (Baron, 1961). He should be restrained, cautious and kind, so that excessive credulity not to turn into recklessness and excessive distrust not to embittered citizens (Machiavelli, 1998). In contrast to Plato, who in his early works advocated for equality and justice, in income distribution, in particular, Machiavelli saw
