The eye scanned the whole area of California Essay

The eye scanned the whole area of California - Essay Example Taking a closer look, the observer began to notice something. It was odd yet very real. Both places if examined at a certain perspective become uncannily similar. To start with, both have labels thrown at them. The enclave for the upper class people is called gated community while the ordinary is called non-gated community. At the start both communities were already type-casted into something that may or may not be true. There is already a sense of expectation for both communities to perform or behave in a certain way. And the outcomes are weighed using only pure presumptions. The first thing that the observer noticed was that residents in both places seldom interacted with each other. Two neighbors in the gated community went out to pick up the newspapers and did not bother to say good morning or hello. Compare that to two neighbors this time in a non-gated community who also came out to do their assigned task of picking up the morning paper, and guess what happened Although the distance between the two houses in this lower middle class neighborhood are much closer to each other, both men were too absorbed in what they are doing that they di d not bother to look up. Everybody is doing their own thing; it does not matter if the guys are wearing Rolexes or cheap Japanese watches, the interaction between humans are at a very intensity. Few words are spoken, people are quiet, except for the Moms who from a distance are the ones whose mouths are always in use. Looking down on the physical surroundings, the observer noticed that in both locations dirt are piling up in the usual places. The rooftops for those much older houses begin to accumulate rotting leaves and the dust coming from the nearby dessert had also been collected in the gutters. The cat in the front lawn of the upper-class neighborhood is as bored as his whiskered cousin down the road five miles away. Also, the harried mom in the rich enclaves looks as distraught as the mother in a typical suburb who could not make her child eat breakfast while frantically trying to prepare her for school. For time is ticking in both places and it moves at the same speed. The rich and poor all have the same twenty four hours, everyone now is gearing up for the morning rush and nobody can make time stand still. In the afternoon both communities seemed no man's land as many of the folks had already left for work. The observer recorded that the toddlers left behind by their parents are being take n cared of by people not related to them judging by their facial features and other characteristics. It (observer) would later take note that money is given to them at the end of the day when Mom and Dad comes back from the office. And finally with regards to the baby sitter - which both working parents from both communities badly needed - when these hired help enter each respective house, immediately they went for the remote and watch TV. This phenomenon is again the same in both communities. As dusk begins to fall, the same golden sun can be seen dipping closer to the western side of both communities. And of course the moon is in its usual place and the stars too, the night sky can be enjoyed irregardless of the address. The moths are having a good time in both communities and they were attracted to the burning lamp-posts and did not care if the one is more expensive than the other. At night

High Cholesterol :: Health, Dementia, Alzheimers Disease

Evidence is increasing concerning an association among vascular risk factors in midlife with an increased risk of both Alzheimer’s disease and vascular dementia decades later (citation). Diverse studies have found total cholesterol measured in midlife to be a significant predictor of subsequent dementia (Whitmer et al., 2005), mild cognitive impairment (Kalmijn et al., 2000) or cognitive decline (Kivipelto et al., 2001). Total cholesterol on midlife was also associated with Alzheimer’s disease (AD) in some studies (Kivipelto et al., 2001) and especially with concomitant hypertension (Beeri et al., 2009). Meanwhile, the exact mechanism of high blood cholesterol in dementia is not known, because cholesterol is not able to pass the blood-brain barrier (BBB) (Bojanic et al., 2010). Beyond that, observational studies have yielded mix results for lipids levels and cerebrovascular disease risk (Bowman et al., 2003). Of interest, lipid abnormalities have been also implicated in the pathogenesis of ischemic cerebrovascular disease (Demchuk et al., 1999; Goldstein, 2007). Stroke contributes to the development of cognitive disorders in nearly 20% of elderly patients (citation). Stroke related features such as multiple strokes, white matter lesions, left hemisphere infarct location, atrophy, and volume of infarcted tissue are associated with an increased risk of post-stroke dementia (Rasquin et al., 2004). Nevertheless, even though a decrease in cholesterol concentrations with statins can reduce the incidence of stroke in high-risk populations and in patients with a stroke or transient ischemic attack (Amarenco et al., 2006), serum cholesterol traditionally has been considered a poor predictor of total stroke risk (Ansell, 2000) and epidemiological evidence has failed to demonstrated a clear relationship between the risk of stroke and serum cholesterol levels (citation). Mild cognitive impairment (MCI) refers to the transitional state between the cognitive changes of normal aging and very early dementia (Petersen and Negash, 2008). MCI is defined as memory deficits with preservation of other cognitive and functional brain activities (Nestor et al., 2004). However, whether the MCI results from neuronal loss within circuit-specific pathways involved in learning and memory (Verkhratsky et al., 2004) and/or from cerebrovascular deregulation within these pathways (Iodecola et al., 2004) remain debatable. The aim of the current study was to determine whether a cognitive impairment associated with elevated plasma cholesterol levels over aging is related with structural pathology or white matter disease (vascular lesions?

The Subtipes of ADHD Free Essay Example, 2000 words

Of all the subtypes of ADHD, the most common is the combined, followed by the predominantly hyperactive-impulsive. The predominantly inattentive subtype is the least common of them and is more common in girls than in boys, compared with other medical conditions that are found more in boys than in girls. That is because the symptoms of inattention are more subtle, less detected and cause the diagnosis of ADHD in children/adolescents to take longer to complete or, in many cases, they even go unnoticed. People with a disorder of attention deficit hyperactivity disorder (ADHD) have difficulty concentrating, and being attentive to the completion of complex tasks in the least. They often have trouble staying up, waiting their turn and often act impulsively. Although these behaviors can be found in all human beings, they are present in abnormally pronounced and prolonged in those with ADHD. They are also present in all the circumstances of life (not just at school or just at home, for exam ple).

Three symptoms primarily characterize the presence of ADHD: inattention, hyperactivity, and impulsivity. They may be present in varying degrees. In the vast majority of sufferers, ADHD has a neurological origin which may depend on heredity and environmental factors. Experts are adamant about this that ADHD is not caused by unmet emotional needs or psychosocial problems, although it can be exacerbated by these factors. ADHD is usually diagnosed around the age of seven (Davis-Berman, Pestello, 2010). However, children with ADHD have challenging behaviors before they return to school, often at the age of 2 years. There is no link between ADHD and intelligence of the child. Academic difficulties suffered by most children with ADHD are often associated with behavioral disorders or attention deficit disorder, bu t not to the lack of intelligence.

Social And Economic Effects Of British Imperialism

A period of colonial expansion by the United States, European powers, and Japan. This took place during the late 19th and early 20th centuries, and marked a large pursuit of oversea territories. New imperialism spread nations influence either directly or indirectly, and also spread the political, cultural, and economic values. Imperialism of free trade British imperial economic ideals were jarringly different from the previously prevalent mercantilist doctrines of earlier centuries. The mercantile doctrines declared that trade was finite, and if one nation had an increase in trade, another would have a decrease.

The canal was built to reduce the distance from Europe to Asia, and succeeded, nearly halving the travel distance. This meant that shipping costs were reduced, and increased the goods available on the world wide market. Much conflict arose from the British control of the canal, eventually resulting in an uncooperative and highly nationalist Egypt. Boer War The Boer War was fought with the South African Republic and the Orange Free State on one side against the British Empire. It was fought over the British Empires influence in South Africa. Starting in 1899, and ending in 1902 with the British victorious, the Boer War was a short but violent war. The Boers were not opposed to guerilla tactics, and held a strong resistance. In retaliation, the British placed boer children and women in what they called concentration camps. These camps were responsible for the deaths of many Boers, who died from disease and exposure. Great trek The Great Trek was a migration of the Dutch speaking settlers in Africa, who traveled from the Cape Colony, also known as Cape of Good Hope, into the interior of what is now South Africa. The Dutch settlers were looking to live outside of the Cape Colony’s British control, and the Trek was a result of tensions between Boers and the British Empire.

Development Of A Child s Social And Emotional Development

Within the area of child development there have been many scientific studies which have formed our understanding of children’s social and emotional development, within this essay I am going to look at some of the theses developmental theories and how they have impacted modern day society in understanding the development of a child’s social and emotional development. Development is the pattern of change that begins at conception and continues through the lifespan (Santrock, 2008, p.5) Emotional development is the development of a child’s expression, understanding, and how they regulate their emotions from birth through late adolescence. Piaget is one of the first people to look at developmental theory and through her theoretical developments, the foundation for modern day developmental theory was laid. The Key concepts of Piaget’s theory are vital in understanding many of the contemporary developmental theories today. One of the key theoretical concepts developed by Piaget is adaptation ‘adapting to the world through assimilation and accommodation (Atherton, 2010).’ adaptation is crucial to theoretical concepts of development, it states that each child passes through various stages of development in which a child has to adapt to individual changes in their social environment, psychological development and personal development.
