Population Growth and Control - Essay Example In other words, it is a ratio: population over resources. If a given environment has a population of 10, but there is food and drinking water enough for only 9 people, then that environment is overpopulated, while if the population is 100 individuals but there are food and water enough for 200, then it is not overpopulated. Over population can result from increases in births, a decline in mortality rates, which is linked to increases in life expectancy, or from an unsustainable use and depletion of resources. Advances in technology can reduce the threat of overpopulation by making new resources available, or by increasing the productivity of existing resources. Resources to be taken into account when estimating if an ecological niche is overpopulated include clean water and air, food, shelter, warmth, or other issues related to survival. In the case of human beings, there are others such as arable land and, for all but tribes with primitive lifestyles, lesser resources such as unemployment, money or other economic resources, education, fuel, electricity, healthcare, proper sewage treatment and waste management, and transportation. In the context of human societies, overpopulation occurs when the population density is so great as to actually cause an impaired quality of life, environmental degradation, or a long-term shortage of essential goods and services. Overpopulation is not merely an imbalance between the numbers of individuals compared to the resources they need to survive, or a ratio of population over resources. This is because such an imbalance may be caused by any other number of factors such as bad governance, war, injustice and exploitation, etc. When other such factors come into play in a certain locale, and population density cannot be shown to be the major cause, overpopulation cannot be conclusively said to occur. The world's human population is currently growing by more than 75 million people per year. This is down from a peak numerical growth of about 88 million per year in the late 1980s. About half the world lives in nations with sub-replacement fertility, and population growth in those countries is due to immigration. Thomas Malthus (1798) argued that if left unrestricted, human populations would continue to grow until they would become too large to be supported by the food grown on available agricultural land. He proposed that, while resources tend to grow linearly, population grows exponentially. At that point, the population would be restrained through mass famine and starvation. Malthus (1798) also argued for population control, through "moral restraint", to avoid this happening. As the population exceeds the amount of available resources, it decreases, since the lack of resources causes mortality to increase. This process keeps the population in check and

Another way of treatment is to provide the necessary amount of iron, which is necessary for the correct functioning of hemoglobin. Anemia is a pathological condition characterized by a decrease in the number of red blood cells and (or) hemoglobin per unit volume of blood (Halwachs-Baumann, 2012). Possible to speak about anemia as a condition that is characterized by a decrease in the formation of red blood cells or an increase in their degradation, or a combination of both factors. Red blood cells and hemoglobin, which is contained in them, play an important function of transporting oxygen to the tissues. Thus, reducing the number of red blood cells and hemoglobin causes insufficient provision of oxygen to tissues. Acute posthemorrhagic anemia. Acute posthemorrhagic anemia is caused by rupture or erosion of the vessel wall through mechanical trauma, ulcerous disease of stomach, pulmonary tuberculosis and bronchiectasis. Color index = 0,85-1,1. Lack of qualitative and quantitative changes in erythrocytes is observed. Abrupt decrease in the number of circulating red blood cells causes hemic hypoxia to which kidneys respond by increased synthesis of erythropoietin. This peptide is a hormone of erythropoiesis and its role lies in stimulating the formation and maturation of erythroblasts in the bone marrow. Proliferation of erythroid sprout becomes noticeable at 4 and 6 days after hemorrhage. In the blood the number of reticulocytes and polychromatic red blood cells increases and also appears rare normocytes. These changes indicate a high regenerative ability of the bone marrow.

Assess the impact of Multi- (or Trans-) National Corporations on international relations. Illustrate your points with examples from the activities of named corp - Essay Example Different markets have welcomes the move taken by such multinational giants but some of them have resisted the affect which has been created by them. Such is the eventual effect by these multinational corporations that many local businesses have winded up in a quick manner, thus putting them out of business in the wake of sheer competitive activity that these multinationals bring with their set agendas. The impact however has been on both sides of the divide – good as well as bad. The results have similarly been lopsided at times, favoring the business regimes in certain cases while bankrupting the parent organization in other instances. The sort of impact these multinational corporations have had on the global relations is something to ponder upon deeply though. This is because it is the international platform which indeed lays the success or failure basis for these multinationals. (Dunning, 2001) The multinational corporations worldwide face a number of challenges when they decide to go global. This is a common problem that they face since they do not have any prior knowledge or understanding of the new territory that they will do their business from. However what best they can do is to find out and research the strengths and weaknesses of this area and hence upon getting the much needed knowledge, base their theories and strategies in a much more effective and efficient manner. This will help one and all to better understand what the new territory, region or country offers the business and the people associated with it. The best thing is that the benefits and disadvantages are determined even before the multinational corporation goes the global way and thus it saves itself from embarrassment which it might face without having proper knowledge and adequate research within it. The significant thing here is to get prepared and be ready for what is to come in the future as

Have services closed the gap in delivering appropriate support in dual Literature review

Have services closed the gap in delivering appropriate support in dual diagnosis working - Literature review Example Likewise, patients that suffer from mental illness are quite likely to sustain their substance use habits throughout their life as compared to people who are mentally healthy (Mueser, Noordsy, and Drake 6). Therefore, it can be said that the disorders of an individual’s mood serve as the risk factor for other disorders that are related to the use of substance and vice versa (Westermeyer, Weiss, and Ziedonis 69). Depression, anxiety and tension are some of the types of upsets in the mental health (Department of Health cited in The Scottish Government). Substances most commonly abused are marijuana, heroin, tobacco, alcohol and alcoholic medicines. Treatment of such people requires the medical practitioner to study the history of the individual and find out which of the two occurred with the individual first. Either he/she acquired the mental illness first which probably caused him/her to consume drugs in order to relieve the tension, or else, he/she first became addicted to dru gs which later led the individual to the deteriorated mental health and low self esteem. There are many ways this can happen. For instance, some people get the psychotic episode triggered upon smoking marijuana (â€Å"Dual Diagnosis†). ... Once someone gets addicted to a substance, he/she starts taking it more frequently than others would mostly do. In such circumstances, all an intervention can do is to reduce the frequency with which the substance is consumed by the client. Thus, a service provider may effectively reduce the quantity of substance consumption, though the achievement of quality in intervention requires consideration of the problem at a much detailed and deeper level. Many service providers resort to such methods of treatment as counseling, prescribing substitutes for substances and encouraging group work. Mostly, these are the only techniques available to most practitioners, and their usability is limited. Reaching the correct underlying factors is extremely essential for appropriate treatment, which can not be achieved unless the addiction has been reduced to a considerably lower level. â€Å"If your client has chronic substance dependence, making substance treatment successful has to be the goal ove r accessing mental health services† (Thomas). The service of mental health assumes the main responsibility of offering comprehensive care to the people that suffer from such mental problems as co-morbid substance use problems and schizophrenia. Mental health service can be used to provide people with long term care and supervision than most services related to substance misuse can offer. According to results of the research conducted by (Menezes cited in Hughes 5), one third of the total number of users of mental health service are individuals that have combined problems of mental health. Cannabis, alcohol and other stimulants are some of the most widely consumed things

Relationship - Essay Example At only about two months, Fudgee stood out among the rest of the litters due to her remarkable talent: she could climb two flights of averaged-stepped residential stairs just to be with me. From the first time she climbed such a formidable task as a young pup, my affection has been directed to her. Fudgee had such notably noticeable facial expression as a young pup. She would look at you as if always begging for mercy. Her cute little eyes are virtually obliterated from the shaggy and unruly hair. She opens her mouth to show the tiny red tongue while unceasingly wagging her tail. When confined to a pet cage with her siblings, I noticed early on that whenever I would come out from my room and pass by, she is the only one awake, staring at me – as if there was no sleepy bone in her being. I recognized then, that there must be something special about this pup. I observed this when I work on my special place at home. I usually spend my leisure time at a loft overlooking our houseà ¢â‚¬â„¢s terrace where my laptop is strategically situated. As soon as I start to climb the stairs, Fudgee is right behind me. She would snuggle comfortably at my feet while I navigate the Internet for email messages or respond to comments from friends at my Facebook page.
