Albert Einsteins Biography - 2256 Words

Albert Einstein The man who would become one of the most famous minds in the history of the known world, the great thinker Albert Einstein, was born in a small city in the WÃÆ' ¼rttemberg region of Germany on March 14, 1879. He was born in Ulm to Jewish parents Hermann and Pauline Einstein (Biography 1967). At birth, Einstein had a proportionately large head and his parents went to their doctor, fearing they had a deformed child and considered measures such as confinement in an institution as was normal for physically deformed children of the period. The physician told them that the childs head was fine and that his large head was fine and that the irregular shape would normalize too in time (Specker 1979). Even his grandmother claimed that he was much too fat, much too fat! It seems the whole family found fault in the tiny Albert from the beginning and believed him to be mentally slow (Specker 1979). Theirs was a relatively secular household and Alberts parents taught him to think individually and to appreciate the sciences. Einsteins eventual love of science came in part no doubt due to his fathers business which was in the manufacture of electrical equipment. His mother was a homemaker, as was the lot in life for most women of the western world in the late nineteenth and early twentieth century. Still even in this domestic capacity, Pauline Einstein showed herself to be an extremely bright woman who encouraged her son in his early interest of science.

Animal Abuse Facts and Information

Within the animal protection movement, the term animal abuse is used to describe any use or treatment of animals that seems unnecessarily cruel, regardless of whether the act is against the law. The term animal cruelty is sometimes used interchangeably with animal abuse, but animal cruelty is also a legal term that describes acts of animal abuse that are against the law. The state laws that protect animals from abuse are referred to as animal cruelty statutes. Abuse Standards for Farm Animals The term animal abuse can also describe violent or neglectful actions against pets or wildlife. In cases of wildlife or pets, these animals are more likely to be protected or are better protected than farmed animals under the law. If cats, dogs or wild animals were treated the same as cows, pigs, and chickens in factory farms, the people involved would likely be convicted of animal cruelty. Animal advocates consider factory farming practices like debeaking, the use of veal crates or tail docking to be animal abuse, but these practices are legal almost everywhere. While many people would call these practices cruel, they do not constitute animal cruelty under the law in most jurisdictions but fit the term animal abuse in many peoples minds. Animal rights activists oppose not only animal abuse and animal cruelty, but any use of animals. For animal rights activists, the issue is not about abuse or cruelty; its about domination and oppression, no matter how well the animals are treated, no matter how big the cages are, and no matter how much anesthesia they are given before painful procedures. Laws Against Animal Cruelty The legal definition of animal cruelty  varies from state to state, as do the penalties and punishments. Most states have exemptions for wildlife, animals in laboratories, and common agricultural practices, such as debeaking or castration. Some states exempt rodeos, zoos, circuses and pest control. Others may have separate laws banning practices like cockfighting, dogfighting, or horse slaughter. If someone is found guilty of animal cruelty, most states provide for the seizure of the animals and reimbursement for expenses for the animals care. Some allow counseling or community service as part of the sentencing, and about half have felony penalties. Federal Tracking of Animal Cruelty Although there are no federal statutes against animal abuse or animal cruelty, the FBI tracks and collects information about acts of animal cruelty from participating law enforcement agencies across the country. These can include neglect, torture, organized abuse and even sexual abuse of animals. The FBI used to include acts of animal cruelty into an all other offenses category, which did not give much insight into the nature and frequency of such acts.   The FBIs motivation for tracking acts of animal cruelty stems from the belief that many who practice such behavior may also be abusing children or other people. Many high-profile serial killers began their violent acts by harming or killing animals, according to law enforcement.

Good vs. Evil free essay sample

An analysis of the concept of good versus evil in the novel Lord of the Flies by William Golding. This paper begins with a description of the books questioning of the innate goodness of mankind. The ways in which the author demonstrates the split between good and evil, this dual nature of humanity, is explored through an examination of the story, setting and characters in the book. In his novel Lord of the Flies, William Golding forces us to question whether people are innately good, or whether what we call civilized behavior is only forced out of us as long as society demands it. In his vision as reflected by the novel, most of us need the constraint of societys rules to remain civilized and not descend into an uglier form of life where cruelty and abuse of power are easily rationalized or even celebrated. He suggests that instinctively we may be barbaric, not good or kind.

Free sample - Euthanasia. translation missing

Euthanasia. EuthanasiaEuthanasia is the intentional termination of life of a very sick person's life in order to relieve them of their suffering. This is usually in cases where the person has an incurable condition. There are other instances where some people want their life to be ended. In many cases, it is carried out at the person's request but there are times when they may be too ill and the decision is made by relatives, medics or, in some instances, the courts. Euthanasia is classified in three different ways. These include voluntary, non-voluntary, or involuntary. Voluntary euthanasia is also termed as assisted suicide and refers to a situation whereby a patient brings about his or her own death with the assistance of a physician. In this case, the patient consents to his or her life being terminated. Those who believe in voluntary euthanasia argue that if an individual has a tormenting illness, he may have intolerable pain that may be a burden to his life. Terminal illness also makes one to be too dependent on others especially the close relatives and friends. It is argued that a patient who has been on a life support machine for long may have voluntary wish to die. However he may not be able to commit suicide without assistance, and therefore voluntary euthanasia may be applied if the patient had expressed such a wish. Non-voluntary euthanasia is conducted where the consent of the patient is unavailable. This is implemented when a person is not in a position to decide or have his wishes known. It mostly occurs in cases where the person is in a coma, the individual is too young, senile, or has severe brain damage. If an individual is disturbed mentally to such an extent, then they should be assisted through non- voluntary euthanasia (Kaveny Murphy, 1997). Involuntary euthanasia is conducted against the willpower of the sick person. In this case a patient's life is ended without the patient's knowledge and consent. Often, the patient may be unconscious or extremely sick to depict what is going on. Voluntary, non-voluntary and involuntary euthanasia can further be categorized into passive or active variants. Passive euthanasia may involve the withdrawal of basic treatments such as the administration of antibiotics that are necessary for life continuity. For active euthanasia, poisonous substances that are lethal may be used to terminate individual’s life and hence making this the most controversial means. There are arguments about whether euthanasia is a moral issue or not. These arguments are brought out in the arguments against euthanasia which puts through the issues that life is sacred, the act devalues life, it is against the will of God, the act is against the best interests of the person, it can be abused due to pressure from other interested parties, improved palliative care can be a solution to the suffering of the patient, if unregulated doctors may use it as a loophole not to be committed in their noble duty to care for patients. Arguments against euthanasia have been supported by current practical arguments which states that:  · Proper application of painkilling measures may render euthanasia useless.  · There's no way of properly regulating euthanasia  · Allowing euthanasia will lead to less good care for the terminally ill  · Allowing euthanasia undermines the commitment of doctors and nurses to saving lives  · Euthanasia may become a cost-effective way to treat the terminally ill  · Allowing euthanasia will discourage the search for new cures and treatments for the terminally ill  · Euthanasia undermines the motivation to provide good care for the dying, and good pain relief  · Euthanasia gives too much power to doctors  · Euthanasia exposes vulnerable people to pressure to end their lives  · Moral pressure on elderly relatives by selfish families  · Moral pressure to free up medical resources   Patients who are abandoned by their families may feel euthanasia is the only solution (Kaveny Murphy, 1997). There are also ethical arguments about euthanasia. some of the ethical arguments states that euthanasia weakens society's respect for the sanctity of life, accepting euthanasia accepts that some lives (those of the disabled or sick) are worth less than others, voluntary euthanasia is the start of a slippery slope that leads to involuntary euthanasia and the killing of people who are thought as undesirable, euthanasia might not be in a person's best interests, euthanasia affects other people's rights, not just those of the patient (Moreno, 1995). On the contrary arguments for and against euthanasia seem to be superseded by the principle of double effect. The principle of double effect; also commonly referred to as double-effect reasoning, involves ethical criteria for analyzing the permissibility of acting on behalf of the patient. For instance, terminating a patient’s pain will lead to an effect of death, which should be avoided under normal circumstances. However, for this principle to hold there are certain things which must be in place. The criteria mention that an action may be justifiable when the harmful effects cannot be separated from good effects. The nature of the act should however meet the basic moral ethics and harm should be minimized. In the society today euthanasia is also met with negative reception in the religious perspective of life. Religious people don't argue that we can't kill ourselves, or get others to do it. They know that we can do it because God has given us free will. Their argument is that it would be wrong for us to do so. They believe that every human being is the creation of God, and that this imposes certain limits on us. Our lives are not only our lives for us to do with as we see fit. To kill ourselves, or to get someone else to do it for us, is to deny God, and to deny God's rights over our lives and his right to choose the length of our lives and the way our lives end. Religious people in the soci ety may at times discredit euthanasia due to the belief that human beings are bound to suffer, as it brings them closer to God. Other arguments against euthanasia state that we need to demystify the myths and stigma associated with terminal illness by helping the patient and their relatives to cope and face the inevitable challenges (Panzer, 2000). This will help in adjusting to the sad scenario that is experienced upon the diagnosis of a terminal illness. It is important to encourage the patient to remain hopeful of the eventual healing. Talking to loved ones about ones illness will help interact freely with those who care about you. It is important to learn about the physical effects of the illness and control the symptoms in order to reduce pain, with loss of appetite and fatigue. In the American society today euthanasia has been met with morals, values and religious undertones. As a national Policy euthanasia is not supported in America. America as a nation stands firmly on the line of morality and societal values. However, there some states in America which have legalized euthanasia. The argument for making euthanasia legal is that the individual's freedom entails liberty or choice in all matters as long as the rights of any other person are not infringed upon. In the contrary, the argument that does not support the legalizing of euthanasia is that it negates the value of human life. It therefore follows that euthanasia may be abused by people who have wrong criminal intentions. A financial motive is sometimes advanced in favor of euthanasia (Keelan, 2006). It is quite expensive to maintain terminally ill persons and this may amount to wastage of resources when such patients succumb to their suffering in the long run. It costs money from the family of the government to keep terminally sick people on life support which will be wasted resources if they eventually die. These arguments informed the passing legal framework in three states of America, Washington, Oregon and Montana. However, looking at the national level public opinion on euthanasia is purely informed by religious affiliations and culture. In Christian perspective the church and especially the catholic and the Anglican Church euthanasia is not advocated for. According to the catholic catechism an act that is administered to reduce pain by causing death goes against the human dignity and it is disrespect to God. The error of judgment into which one can fall in good faith does not change the nature of this murderous act, which must always be forbidden and excluded (Murray, 2005).   However, the Lutheran church in November 9, 1992 adopted the famous "End of life decisions'' which seem to support euthanasia as a way of relieving those with severe suffering out of terminal illness. This included several decisions just to quote but one: When medical judgment determines that artificially-administered nutrition and hydration will not contribute to an improvement in the patient's underlying condition or prevent death from that condition, patients or their legal spokespersons may consider them unduly burdensome treatment. In these circumstances it may be morally responsible to withhold or withdraw them and allow death to occur (Benoway, 1992). The Orthodox Church firmly does not support euthanasia as it is perceived as committing murder by the people involved. This act is therefore sinful in nature (Perrett, 1996). Islam and Buddhism also respects the sanctity of life and therefore euthanasia is firmly prohibited and is seen as a violation of God's work and interfering with human kind. Euthanasia has since time immemorial attracted serious legal battles. In Montana in the United States of America a lawsuit was brought against the local government to allow euthanasia. This land mark judgment gave way for competent terminally ill patients to make decisions about when to take their lives. On December 5, 2008, state District Court judge Dorothy McCarter ruled in favor of a terminally ill Billings resident who had filed a lawsuit with the assistance of Compassion Choices, a patient rights group. The ruling illustrates that competent, terminally ill patients have the right to self-administer fatal doses of medication to as prescribed by a physician (Kaveny Murphy, 1997). Physicians who prescribe such medications have not broken any legal law to prompt their punishment. Recommendation Euthanasia is an act which continues to elicit reactions from the world over and this comes from mainly religious affiliation and culture. On one hand this research has found out that ethical arguments which points out that if supported it can lead to undesirable execution of people, it can also erode the professionalism of medical personnel who should be committed to offering care to patients. On the other hand this research points out that even practical arguments against euthanasia clearly shows that proper measure for pain reduction makes euthanasia unnecessary. Since there are no proper measures for the regulation of euthanasia, it is almost impossible to justify the reason of applying it regardless of the situation. References    Appel, J. (2004).

Management of Occupational Health and Safety Essay

Management of Occupational Health and Safety - Essay Example "Now 25 years on, it is time to give a new impetus to health and safety at work. Too many deaths still occur at work. Each death or serious injury in the workplace is a tragedy; a tragedy that causes devastation for workers, their families and loved ones; a tragedy which, perhaps, could have been avoided in the first place" says Deputy Prime Minister in his forward. (http://www.hse.gov.uk/revitalising/strategy.pdf) A great number of working days are lost every year due to ill-health and injury showing the importance of reducing the incidence of work related ill health and accidents. Government and connected organisations have been trying all ways of reducing such fatalities and injuries. Government also launched their Securing Health Together (SHT) programme and the main intention had been controlling work related ill health (WRIH). There were necessities and compulsions that forced the government to set targets and specific aims. While doing so, several priority areas have been identified. "The aim of Revitalising Health and Safety is to... There was an immediate need of upgrading health and safety measures in Britain and studies and surveys have shown that ill health and accident rates were spiralling up instead of coming down and this alarmed the Government. There were many fatalities especially in the construction industry. There are many workplaces similar to construction where health and safety hazards are rampant and they needed immediate government attention. "The challenge for all stakeholders is to reduce deaths, injuries and work-related ill health. Government Departments are required to Demonstrate that they are leading by example and are using best practice in health and safety management" http://www.ogc.gov.uk/documents/InformationNote2100.pdf Government and HSC decided to work in partnership all connected parties to introduce a series of reforms and improvements keeping workers' health and safety as goals. This ambitious project was undertaken with the specific need of better safety and health measures to meet the requirement of the changing, globalising world and expanding businesses in need of fit and secure work force. IMPACT ON SAFETY: The introduction of revitalisation for a period of ten years made tremendous impact on safety of workers at all workplaces. In Britain, there was not a single work place which remained untouched at one point or other as a result of this measure. The immediate targets were to "reduce the number of working days lost per 100,000 workers from work-related injury and ill health by 30 by 2010; reduce the incidence rate of cases of work-related ill health by 20% by 2010; reduce the incidence rate of fatalities and major injuries by 10% by 2010; and

Explain what the digital divide is; in your answer discuss the Research Paper

Explain what the digital divide is; in your answer discuss the advantages and disadvantages of improving the digital divide - Research Paper Example What does it mean? How did it happen? Does it have any positive or negative effect on our society? What benefits can be had from promoting a digital divide? Should the digital divide be promoted within our society as something that should be supported or not supported? These are but a few of the questions that I am looking forward to answering within the next few pages. I would like to start off this paper by presenting the readers with a basic discussion of the digital divide and its meaning. While the economic divide pertains the method by which the people of the world are separated by the amount of money that they have, the digital divide separates people in terms of their existing or non-existing access to the internet and other forms of communication technology. According to experts, the digital divide exists as a barrier between the urban and rural areas (Rouse, 2005). Upon closer inspection, one will come to the realization that the digital divide, also known as the digital split, refers not only to the people who have easy access to the internet and those who dont, but also among those who have or dont have access to information and communications technology. The term digital divide was then coined, in the 1990s in order to help explain the complex scenario. Due to the globalized market that exists between countries, the presence of the internet and other forms of telecommunication that can help ease the transfer of business information has become one of the utmost important business tools in our era. However, not all countries have state of the art information and communication technology infrastructures in place so the digital divide has already gone beyond borders, thus creating what is now known as the Global Digital Divide. Therefore, the digital divide is not limited to the social or economic statues of people alone. It also includes the members of society who use almost obsolete computers on infantile internet

Depression: Neurobiological and Neuropsychological Models

Depression: Neurobiological and Neuropsychological Models A correlation of Neurobiological and Neuropsychological cognitive model toward Depression Abstract Depression is a chronic illness that has stirred centuries of debate regarding its mechanism. Notwithstanding the sharp contrast among theories that have been proposed to explain the underlying source of depression from different perspectives, all of them accept the fact that it affects body, mood and even thoughts of individuals and as World Health organization predicted, it is expected to be the second mental disorder by 2020. The most compelling models regarding the source of depression and its treatment in this realm are Monoamine model and cognitive model. Monoamine model claims that depression has a biological source and it is caused by neurochemical imbalance in individuals, whereas base on cognitive model impaired information processing and negative biases are the key factors in the development of depression. The present paper attempts to assert the missing point in each of these theories and propose an explanation about the mechanism and treatment from two similar perspectiv es: Cognitive Neurobiological and Cognitive Neuropsychological, which work as a combination of Monoamine and Cognitive model. Both of these models categorize biases based on two pathways: Bottom- Up and Top- Down processing. With the help of cognitive Neuropsychological model, it is shown how negative affective processing can be the main core of depression, while Neurobiological model will show how hyper activation and hypo activation in different brain regions can develop depression. Therefore, a correlation of both models can explain underlying source of depression and thus can be used for modifying depression symptoms. Definition: Depression is a universal mental disorder that has been growing at an alarming rate. It will be the second mental disorder by 2020; most people will be affected by depression in their lives either directly or indirectly, through a friend or family member. It is a severe and even painful disorder that will influence almost all aspects of sufferer’s life. Most people misdiagnose depression as feeling down, but depression is not a sign of weakness and is not the same as passing blue mood. According to UK medical reference, depression will be identified and categorized base on its symptoms, which is called ICD10 clinical criteria of depression and depends on the number of symptoms, types of depression, can be diagnosed. Symptoms are: Persistent sadness or low mood Loss of interests or pleasure Fatigue or low energy Disturbed sleep Poor concentration or indecisiveness Low self-confidence Poor or increased appetite Suicidal thoughts or acts Agitation or slowing of movements Guilt or self-blame If an individual suffer from 4 of these symptoms most of the time for at least 2 weeks, he/she will be diagnosed with mild depression, and with 5 to 6 of symptoms he/she suffer from moderate depression and in dangerous cases or severe depression, depressed person has more than 6 symptoms. Models of depression: A significant number of studies have been trying to reveal the mechanism of depression from different perspectives. Among the biologically based theories, the most reliable model that arguing reasonably about underlying source of depression and proposing acceptable treatment is Monoamine model. Monoamines are neurotransmitters and neuromodulators that include serotonin, dopamine, norepinephrine, and epinephrine. The basic concept is that neurotransmitter imbalance within the brain is the main core of depression and neurotransmitters can be balanced again by using antidepressant medication. Type of antidepressant medication depends on severity of symptoms; for patients suffering from dysphoria (low mood) SSRIs or norepinephrine reuptake inhibitors can be used, while anhedonia patients (ones with the loss of energy and enjoyment of life) should be treated with norepinephrine and dopamine enhancing drugs (SNRIs). Despite their immediate effects at the synaptic level, in approximately 40 % of the cases, they are ineffective in the short time and 30% of patients will suffer from depression within 12 months after recovery. This result suggests that depression is not only the cause of chemical imbalance and psychological factors play an important role in its development. On the other hand, the most prominent and empirically based model of psychological factors of depression is cognitive model proposed by Aaron Beck in 1976. This model claims that negative affective biases, which are negative biases in perception, attention, emotional processing, thoughts and rumination and even memory, will affect individual’s information processing and lack of cognitive control over these negative biases are the main cores of depression. According to this model, depressed people are likely to experience different phenomena such as: negative cognitive triad, think negatively about themselves, their future and even the world; positive blockade, blocking positive information, inhi bitory deficits, inability to disengage from negative stimuli. The model defined depression like an infinite loop, which receive feedback from its components: Figure 1: cognitive model of depression Beck claimed that by the help of cognitive behavioral therapy (CBT) and behavioral activation therapy (BA) negative biases and negative schemata of depressed people can be modified, however the reality was far from his thought and CBT and BA failed to cure depression, therefore scientists try to find a better explanation and treatment. Based on Beck’s cognitive model, two models have been proposed by researchers: Cognitive Neurobiological and Cognitive Neuropsychological model, which are built on the assumption that negative bottom-up and top-down biases are vital in development of depression. Cognitive neuropsychological model: This model was proposed in 2011 and is a combination of Monoamine model and Cognitive model. From neuropsychological perspective environmental factors, genetic factors and personality can change the function of monoamine neurotransmitters; this neurotransmitter imbalance causes negative affective processing biases, which is the impairment of information processing especially in emotional and reward processing and play the main role in development and treatment of depression; and finally the negative affective processing will cause negative schemata in depressed people. In comparison to healthy individuals, who process information in positive way, in depressed people the negative affective processing will change this automatic process more negatively. The difference between Neuropsychological model and cognitive model is in the formation of negative schemata; based on cognitive model negative schemata are a result of early hostile life experience and they influencing the information processing, while cognitive psychological model claims that negative schemata are not the direct result of life experience, instead they are caused by negative information processing biases. Neuropsychological model categorized negative biases proposed by cognitive model into two groups: Bottom- up biases and Top-down biases. Bottom-up biases: Negative biases that give rise to formation of negative schemata are called bottom-up biases and consist of perceptual biases especially negative emotional perception, negative thoughts and rumination and reward- punishment processing biases. Generally, healthy individual perceive positive information or less negative information from environment, while depression makes sufferers to perceive more negative information from a stimulus faster and filter out the positive information. In a study done by Persad and Polivy in 1993, they observed individuals with depression have difficulty when they were shown facial emotion; paucity in identification, perception and even sensation of facial emotion was common in these patients. A series of experiments were conducted as a support for this finding and in nearly all of them biases toward negative part of stimuli is reported. For example in another study, researchers found a reduced sensitivity toward happy faces, but an extreme sensitivity to sad faces. There is also neuroimaging evidence that support their result. There is a known pathway in perceiving information, which consists of Thalamus (responsible for the distribution of afferent signals), the Dorsal Anterior Cingulate Cortex (region that relays top-down cognitive control from the Dorsolateral Prefrontal Cortex) and the Subgenual Cingulate Cortex (a region that integrates emotional feedback from the limbic system and projects to higher-order cognitive structures). Information from environment will pass through this pathway from Thalamus to Amygdala, which is responsible for detecting emotion and finally with the help of Dorsolateral Prefrontal Cortex Amygdala activity will be controlled in order to not to perceive only negative information. Depressed individuals seem to have a longer and more intense Thalamus and Amygdala activity as a response to negative stimuli. They also showed greater activity in Subgenual Cingulate Cortex, which is a region connecting limbi c activity to higher cortical level (Prefrontal Cortex), whereas regions that are responsible for cognitive control, Dorsolateral Prefrontal Cortex and Anterior Cingulate Cortex, showed a reduction in perceptional processing, which means less cognitive control over Amygdala and Thalamus, therefore more negative stimuli will be perceived. Figure 2: negative perceptional biases How we perceive emotion will determine how we think about our environmental events and ourselves. As currently said, depression will induce perception and as a result will alter individual’s thoughts in a negative way. Since Individuals are more likely to discern negative information, it is highly probable that their life events, especially ones that are related to their failure, determine their perspective toward themselves; they suffer from lack of self-steem, since they think they are useless, which gradually will cause more negative perception and more negative thoughts. This situation is like an infinite loop and is called rumination. Different brain regions involve in this process, which again prove lack of cognitive control in depression. As previously discussed, hyperactivity in the Amygdala and Hippocampus increase activity of Subgenual Cingulate Cortex (SCC), which is a connection between lower structural and cognitive part of brain and higher ones, therefore, Medial Prefrontal cortex (MPFC), a specific region that is in charge for internal representation of self, will be activated as a response negative information that is received from SCC. Beside the hyperactivation in these parts, there is hypoactivation in higher levels, especially in Dorsolateral Prefrontal Cortex and Ventrolateral Prefrontal Cortex, cognitive control regions; this reduction causes less control over Amygdala and Hippocampus and result in more negative perceptuational biases. Figure 3: negative thoughts and rumination After this finding researchers went further and tried to determine how depression affects the reward and punishment process. Interestingly they indicate an exaggeration in negative performance feedback, while a reduction in reward seeking behavior. Neuroimaging evidence revealed an increased activity in the Amygdala as a response to negative situation and decrease activation in the Amygdala, Striatal regions, prefrontal cortex, Nuscleus Accumbens and Dorsal Anterior Cingulate Cortex as a response to reward. This evidence supports the claim that was made earlier with respect to impairment cognitive control in depressed individuals. Top-down biases: These types of biases are negative biases that bolster the existence of depressive state and are composed of emotional attention and emotional memory. Not all the information we perceive from environment will be processed; only those that are attended will be selected for further processing. This selecting process in healthy individual is more in favor of positive stimuli, which means greater Rostral Anterior Cingulate Cortex (ACC) activity when they successfully inhibit attention to positive stimuli, while in depressed individual this area cannot be activated in response to positive stimuli and are unable them to disengage their attention from negative stimuli. Disengagement attention requires a top-down mediation from high-level cortical regions, which in depression these regions cannot work properly. Moreover, depressed individuals suffer from lack of selecting and guiding their attention toward positive information and as a result they attend to more negative stimuli. Neuroimagin g studies reveled 4 brain regions that are responsible for the whole process of attention: Ventrolateral Prefrontal Cortex (VLPFC; associated with control over stimulus selection), Dorsolateral Prefrontal Cortex (DLPFC) and Anterior Cingulate Cortex (ACC; associated with disengagement functioning), Superior Parietal Cortex (SPC; associated with shifts in gaze). Depression will affect the activity in these regions: Prefrontal Cortex, especially Perigenual ACC, including Brodmann areas 24, 25, and 32, which will cause negative attentional biases; reduced activity in the right VLPFC, therefore they are less likely to guide their attention toward positive stimuli; decreased activity in right DLPFC and right SPC, which cause an impaired disengagement from negative stimuli; greater activation in ACC when successfully inhibiting attention to negative stimuli and less activity as a response to positive stimuli. Figure 4: negative attentional biases Various researchers claimed that depressed individuals prefer to remember their failure or negative events rather than their success. Their argument is base on the result of differnet tasks in which depressed individuals showed biases in remembering negative stimulus, not for positive materials. They suggest that since these patients are highly probable to perceive and attend negatively, they are more likely to encoding and recalling negative information. Thanks to neuroimaging studies, their claim was proved. As we might know hippocampus is an essential region for episodic memory and is connected to amygdala and as already discussed Amygdala’s activity is increased toward negative stimuli, which lead to increase activity in Hippocampus as well as Caudate and Putamen, regions for implicit memory and skill learning, in negative situation and as result will bolster the recall probability of negative information. Figure 5: negative memory biases According to cognitive model, negative schemata are the most responsible source for developing depression. Base on Neurobiological model, there is a circuit that involve in forming belief and representation of individual’s life, environment and even themselves. The elements of this circuit are: Medial Prefrontal Cortex that is a higher cortical level responsible for internal representation, Anterior Cingulate Cortex that is an intermediate level and a connector between limbic area and Prefrontal Cortex, and finally Amygdala, a lower structural level which detect and process emotion. The high activation in this circuit will cause the maintenance of depression state. Individuals at risk of depression According to cognitive neuropsychological model, we can predict the risk factors of depression and we might be able to prevent its development. The most important factors are: neuroticism, genetic factors and recovered depressed individuals. Neuroticism, which is a personality trait, characterized by anxiety, moodiness, worry, envy and jealousy, is most well-established risk factors for depression in non depressed people, however negative attentional biases are not found in them and it suggest that they only suffer form a bottom-up biases. Fortunately since they do not have the top down biases, their biases might be diminished by help of antidepressant drugs that influence bottom-up biases directly. As well as neurotic individuals, relative of depressed individual are in high risk of depression, since they tend to score higher on measures of neuroticism. Moreover, they show a greater activity in Amygdala as well as a reduced Ventral Striatal responsiveness to reward and less efficien t activation of Parietal and Temporal networks during working memory performance. All together prove the existence of risk of depression in these individuals. Last vulnerable individuals are those who recently recovered from depression. They have behavioral biases toward negative stimuli as well as abnormal activity in Amygdala. All of these vulnerable individuals exhibit bottom-up biases that are similar to depressed people. Conclusion Neuropsychological model and neurobiological model are proposed base on cognitive model and believe that different biases will cause and help the depression state in both depressed people and individuals at risk of depression. According to them, depression is a sequential process that is caused by two pathways: Bottom-up and Top-down biases. Bottom-up biases will influence the lower cognitive and structural level of brain and is the main cause of generating depression, while Top- down affect the higher level and is responsible for maintaining the depressed state. By help of antidepressed drugs, the bottom up biases (perceptional, toghts biases) of depression will be modified and by help of CBT and BT, the top down biases ( attentional and memory biases) will be remit gradually . Figures below are used to show development of depression base on two models. Figure 6: cognitive neurobiological model In this figure the whole process of depression is shown as a loop and as can be seen each step will get feedback to each other, even depressive symptoms will influence the Schema activation, which make the whole system stronger. The blue boxes are brain regions that are described as bottom-up biases, while gray boxes are more higher structural levels or top-down biases, which are responsible for cognitive control. Figure 7: cognitive neuropsychological model: As can be seen the environment event or genetic factors or personality will cause an imbalance in monoamine transmitters, this change cause negative affective biases (perceptual biases), bottom-up biases and lack of cognitive control over these biases, which is a result of environmental trigger as well as bottom-up biases will increase the chance of depression by generating dysfunctional negative schemata; dysfunctional negative schemata will causes more severe and higher level of biases (top-down biases). Green boxes are treatments that can be use for each step.

Development, an Impetus to Urbanization Essay

New ways of thinking about government, science, economics, and religion had brought many changes to America by the eighteenth century. Concern for individual freedoms became so strong that it led to revolution in many lands. In Britain’s American colonies, revolution brought the establishment of a new nation, the United States. In the spring of 1775 few Americans, angry as they were, favored separation from Britain. Support for independence grew over the next six months as fighting continued and the colonists debated the issue. The Americans had declared their independence but still had to win it. They had capable leaders and were strengthened by their dedication to the cause of liberty. The Americans emerged victorious from the Revolutionary War and adopted a plan of government that became a model for other nations (Hinkle, 1994). Since then, modernization and urbanization became the twin paradigms of â€Å"pop culture† from that point on in America. For approximately two hundred years, people in the United States have been wandering towards the fringes in the hunt for reasonably priced domestic shelter, rural community conviviality, and well-preserved and intact nature only to learn that their verdant new neighborhoods are a component of the emergent metropolitan stretch. Modernization describes the process by which a society moves from traditional or pre-industrial social and economic arrangements to those characteristics of industrial societies. Implicit in the notion of modernization is the assumption that there is basically one predominant course of development, namely industrialization and urbanization which were followed by America (Todaro, 1981). This capitalistic and industrially advanced commerce became the impetus of urbanization in America. The relocation of the new technologies furnished the United States its first manufacturing plants, large-scale mills that incorporated spinning and knitting technology in a single factory. As workers drifted into the metropolis in the hunt for employment in the factories, the factory scheme was mainly accountable for the materialization of the urbanized city (Harris and Todaro, 1970). The development of dramatic socioeconomic modifications brought about when wide-ranging automation of assembly systems led to a swing from domestic hand manufacturing to across-the-board factory manufacture. The Industrial Revolution has transformed the visage of nations, creating metropolitan centers involving substantial urban services (Brody, 1989). Viewed in this manner, modernization entails a pattern of convergence as societies become increasingly and inevitably urban, industry comes to overshadow agriculture, the division of capitalistic labor becomes more specialized, colonialism gained a new meaning, and the size and density of the population increase with immigrants coming in from every point in the world (Cohen, 2004). Initially, inhabitants have sought commune, dwelling, and conserved environment in suburbia. People have continuously hankered after sighting their conurbations as human constructions built as one piece. Developers have taken pleasure in a range of imaginings, aiming for revenues from economies of scale and enlarged suburban crowdedness, while swaying opinion on municipal and federal administration to diminish the peril of real estate conjecture (Loomis and Beegle, 1950). Enclosing all environmental hullabaloos in addition to the intricacies of social stratum, ethnicity, and sexual category, several speculate how we mull over the communes Americans construct and make their homes in (Newman, 2006). It is apparent that population size and composition have a great composition have a great many ramifications for all phases of social life. The distribution of a population in space also assumes critical significance. The â€Å"where† may be an area as large as a continent or as small as a city block. Between these extremes are world regions, nations, national regions, states, cities and rural areas. Changes in the number and proportion of people living in various areas are the cumulative effect of differences in fertility, mortality, and net migration (Walls, 2004). One of the most significant developments in human history has been the development of cities. Although many of us take cities for granted, they are one of the most striking features of our modern era. A city is a relatively dense and permanent concentration of people who secure their livelihood chiefly through non-agricultural activities. The influence of the urban mode of life extends far beyond the immediate confines of a city’s boundaries. Many of the characteristics of modern societies, including problems, derive from an urban existence (Cohen, 2004). Urbanization has proceeded quite rapidly during the past two centuries. In 1800 there were fewer than fifty cities in the world with 100,000 or more population. And by 1900, only one in twenty earthlings lived in a city with a population of at least 100,000. Today. One in five people lives in a center with at least 100,000 people (Montgomery, et al. , 2004). Several of the spatial standards and social prospects of the 1800s and early 1900s hang about up till now, layers entwined in protocols, recollection, and experience, in addition to the metaphors of popular culture and the proclamations of draftsmen and urban developers. In the first part of the 1800s, inhabitants, pattern book authors, and engineers created long-term principles of quixotic houses established in picturesque landscape peopled by elite, private neighborhoods (Loomis and Beegle, 1950). Prevalent since the 1840s, the philosophy of female domesticity was married to a trend of mannish home occupancy, stretched out to subsume plebeian males three decades later. Communitarian activities started to have some bearing on draftsmen, landscapers, and engineers, a class of reformers on the up understood they may possibly fashion a transformative societal construction at the outer reaches of the metropolis (Kivisto, 2001). Picturesque enclaves began round about 1850. All over this time, the American suburban abode had turned out to be a private utopia, taking the place of the archetypal town which had taken on a range of Americans’ hopes a thousand years earlier (Satterthwaite, 2005). Nevertheless, it is time to revamp every layer in the discrete metropolitan terrain, and contemplate how to take in hand each variety, keeping in mind that property holder subsidies, developer subventions, and metropolitan services have been dispersed disproportionately over the decades and certain greater impartiality is looked-for. The long-standing enclaves may necessitate conservation, but aid should be rendered in exchange for communal access and construal of their privileged parks and natural terrains (Harris and Fabricius, 1996). New-fangled proposals for picturesque enclaves, such as Llewellyn Park, New Jersey, laid emphasis to communal open area and advanced joint public life (Satterthwaite, 2005). One communitarian community in Mount Vernon, New York, exerted a pull on roughly three-hundred families by putting forward fortification against the biased power and weight of capital; others urbanized model settlements to advance women’s repute through collective services and industrial sustenance (Alexander, et al. , 2004). Most early urban communities were city-states, and many modern nations have evolved from them. Even where the nation became large in both size and land area, the city has remained the focus for political and economic activities, and the core and magnet of much social life. To people of other nations, the city often represents the nation, and this tradition survives in the modern use of a city, such as Washington, London, and Moscow, as a synonym for a nation (Beauchemin and Bocquier, 2004). Industrial-urban centers typically been geographically scattered, and although dominating their hinterlands, have had only tenuous economic and social relations with them. More recently, metropolitan cities have emerged. This phase in urban development does not represent a sharp break with the industrial-urban tradition, but rather a widening and deepening of urban influences in every area of social life. Increasingly cities have become woven into an integrated network (Cohen, 2004). The technological base for the metropolitan phase of urbanism is found in the tremendous increase in the application of science to industry, the widespread use of electric power (freeing industry from the limitations associated with steam and belt-and-pulley modes of power), and the advent of modern forms of transportation (the automobile and rapid transit systems have released cities from the limitations associated with foot and hoof travel, which had more or less restricted growth to a radius of 3 miles from the center) (Todaro, 1981). Steam and belt-and-pulley power techniques had produced great congestion in urban areas by the beginning of the twentieth century. But a number of factors have increasingly come to the foreground and bucked earlier centripetal pressures, including rising city taxes, increased land values, traffic and transportation problems, and decaying and obsolescent inner zones. These and other forces have accelerated the centrifugal movement made technologically possible by electric power, rapid transit, the automobile, and the telephone (Harris, 1988). The result has been the development of satellite and suburban areas, broad, ballooning urban lands linked by beltways that constitute cities in their own right. In population, jobs, investment, construction, and chopping facilities, they rival the old inner cities. They are the sites of industrial plants, corporate offices and office towers, fine stores, independent newspapers, theaters, restaurants, superhotels, and big-league stadiums (Montgomery, et al. , 2004). A good deal of the sociological enterprise is directed toward identifying recurrent and stable patterns in people’s social interactions and relationships. In like fashion, sociologists are interested in understanding how people order their relationship and conduct their activities in space. They provide a number of models that attempt to capture the ecological patterns and structures of city growth (Newman, 2006). In the period between World Wars I and II, sociologists at the University of Chicago viewed Chicago as a social laboratory and subjected it to intensive study. The concentric circle model enjoyed a prominent place in much of this work. The Chicago group held that the modern city assumes a pattern of concentric circles, each with distinctive characteristics. At the center of the city, the central business district, are retail stores, financial institutions, hotels, theaters, and businesses that cater to the needs of downtown shoppers. Surrounding the central business district is an area of residential deterioration caused by the encroachment of business and industry, the zone in transition (Loomis and Beegle, 1950). In earlier days, thee neighborhoods had contained the pretentious homes of wealthy and prominent citizens. In later years they became slum areas and havens for marginal business establishments (pawnshops, secondhand stores, and modest taverns and restaurants). The zone in transition shades into the zone of workingmen’s homes that contain two-flats, old single dwellings, and inexpensive apartments inhabited largely by blue-collar workers. Beyond the zone occupied by the working class are residential zones composed primarily of small business proprietors, professional people, and managerial personnel. Finally, out beyond the area containing the more affluent neighborhoods is a ring of encircling small cities, towns, and hamlets, the commuters’ zone (Harris and Fabricius, 1996). The Chicago group viewed these zones as ideal types, since in practice no city conforms entirely to the scheme. For instance, Chicago borders on Lake Michigan, so that a concentric semicircular rather than a circular arrangement holds. Moreover, critics point out that the approach is less descriptive of today’s cities than cities at the turn of the twentieth century. And apparently some cities such as New Haven have never approximated the concentric circle patterns. Likewise, cities in Latin America, Asia, and Africa exhibit less specialization in land use than do those in the United States (Montgomery, et al. , 2004). Homer Hoyt has portrayed large cities as made up of a number of sectors rather than concentric circles, the sector model. Low-rent districts often assume a wedge shape and extend from the center of the city to its periphery. In contrast, as a city grows, high-rent areas move outward, although remaining in the same sector. Districts within a sector that are abandoned by upper-income groups become obsolete and deteriorate (Satterthwaite, 2005). Thus, rather than forming a concentric zone around the periphery of the city, Hoyt contends that the high-rent areas typically locate on the outer edge of a few sectors. Furthermore, industrial areas evolve along river valleys, watercourses, and railroad lines, rather than forming a concentric circle around the central business district. But like the concentric circle model, the sector model does not fit a good many urban communities, including Boston (Loomis and Beegle, 1950). Another model, the multiple nuclei model, depicts the city as having not one center, but several. Each center specializes in some activity and gives its distinctive cast to the surrounding area. For example, the downtown business district has as its focus commercial and financial activities. Other centers include the bright lights (theater and recreation) area, automobile row, a government center, a whole-sailing center, a heavy manufacturing district, and a medical complex. Multiple centers evolve for a number of reasons (Loomis and Beegle, 1950). First, certain activities require specialized facilities, for instance, the retail district needs to be accessible to all parts of the city; the port district requires suitable waterfront; and a manufacturing district dictates that a large block of land be available near water or rail connections. Second, similar activities often benefit from being clustered together. For instance, a retail district profits by drawing customers for a variety of shops. Third, dissimilar activities are often antagonistic to one another. For example, affluent residential development tends to be incompatible with industrial development (Dentler, 2002). And finally, some activities cannot afford high-rent areas and hence locate in low-rent districts; for instance, bulk wholesaling and storage. The multiple nuclei model is less helpful in discovering universal spatial patterns in all cities than in describing the unique patterns peculiar to particular communities (Todaro, 1981). Structure-function approaches help us to partition social life into discrete structures, including statuses and neighborhoods. They allow us to place a handle on the fluid quality of life so that we may grasp, describe, and analyze it, making it understandable and intelligible. But as many conflict and symbolic interactionist theorists emphasize, the dichotomy between structure and process gives birth to problems that are frequently unnecessary. For one thing, the dichotomy produces difficulty in handling change. Indeed, the word change itself is saturated with certain non-process connotations, implying a shift from one static and relatively stable to another (Loomis and Beegle, 1950). Most of the some of the United States are not necessarily one hundred per cent Americans. This is the result of the continuous social change that has taken place in the metropolitan cities over the past decades. Some cities have especially undergone a vivid transition from rural community to a modern suburb. Language, culture, religion, and ethnic heritage reinforce people’s sense of belonging. These are the bonds out of which will be created new communities. Some people insist that the forces that are making the world into a single economy have separated people from longstanding identities and have, at the same time, weakened nation-state (Davies, 2005). The everyday life of the rural people is uncomplicated and less complex than that of the urban inhabitants, and the rural resident are inclined to keep more of the speech patterns and traditions of their characteristic racial backgrounds (Cohen, 2004). A foremost setback in living in a highly developed city is the high cost of living, owing largely to the continent’s empowered economy (Dentler, 2002). Once, most part of the continent had heavily relied on imports. Transportation expenses were incorporated in the prices of the majority of consumer merchandise. As the residents number rise, housing grows more and more hard to obtain, and it is excessively high-priced when proportionate to housing costs in several of the mainland states. Building materials, nearly all of which are brought in from outside the country, are costly. Residential settlement is limited and expensive, given that much of the land is in possession of corporations and trusts (Harris and Todaro, 1970). Pains have been taken through legislation to correct this state of affairs. Thoroughly-designed housing situated in communities, in which the single-family home yield to high-rise, high-density houses and townhouses and apartment complexes, has become one solution to the lack and cost related to urban housing (Hayden, 2004). Urban settlement some time ago comprised more or less completely of single-family quarters, individual business buildings and stores, small bazaars, and three- or four-story inns. With the upsurge of inhabitants and vacationers since the early part of the 20th century, on the other hand, American states have built increasingly high-rise apartment building houses, hotels, and commercial establishments, with the conventional individual shopkeepers becoming wrapped up into the sets of buildings of shopping centers and supermarkets (Loomis and Beegle, 1950). Urban cities are where the majority of Americans reside at the present. It is the governing American edifying landscape, amalgamating esteemed natural and manufactured ecosystems, lots and single domestic houses. Urban cities are where a massive space of profit-making and residential landed property are bankrolled and erected. It is the locality of most of the charitable toil of fostering and parenting, mirroring both societal and ecological customs. Lastly, urbanized cities are where the large American body of voters live today (Alexander, et al. , 2004). References Alexander, Jeffrey C. , Gary T. Marx, and Christine L. Williams. (2004).
