Forest Soils on Acid Essay -- Ecology Nature Environmental Papers

Forest Soils on Acid Forest ecosystems are important both ecologically and economically. It is arguable that the most fundamental dynamic of the forest ecosystem is the forest soil. The acidity of forest soils can alter the chemistry, biota, and hydraulics of the soil, and thus, alter the soil formation characteristics and the soil composition. It follows that the acidification of forest soils demands a great deal of research and attention. Forest soils are commonly found to have pH readings of 4-6, even in areas of moderate to low acid deposition (Binkley et al, p. 4). In fact, an abundance of forest vegetation thrives on and stabilizes most forest soils at relatively low pH levels. It seems as though forest ecosystems generally thrive upon strongly acid soils. Though forest soils naturally are acidic, problems can occur when the acidity levels are raised artificially through processes such as acid rain. This paper will investigate the effects of higher than normal acidity and acid deposition in forest soils to gain a greater understanding of current and potential problems to forest soils and ecosystems. It is important to remember when discussing the implications of high acid in forest soils that there are several general factors that will alter acidic effects on soil chemistry, hydrology, biota, and weathering. These factors include soil type, soil sensitivity, and the quantity of precipitation. Texture, structure, grain size, and consistence are all crucial to defining the soil type or series and also to the amount of time soil is exposed to acid deposition. In a particular study on humus degradation based on simulated "acid rains" conducted by Greszta et al. (1991) revealed the extent to which soil type influenced ... ...556-563. Mulder, J., J.J.

Argumentative Essay: Women Are Better Politician Than Men

There is a mindset in the current society that men make better politicians than women. In fact, that statement is not true. Women make good politicians too, some are even better than men in many aspects. Women politicians make better politicians because they compromise better, are more trustworthy and cooperative, plus they are more strong-minded as compared to men. One of the best example is Christine Lagarde the first female Minister of Economic Affairs in a G8 economy which is the governments of eight of the world's largest economies(Christine Lagarde, pars. 3).She is also voted as the world's 9th most powerful woman according to Forbes magazine. Women politicians have a more compromising and friendly nature than men. This ultimately becomes a highly useful political tool for political campaign. They tend to face difficult situations with a calm attitude. For example, Ms. Indra Gandhi, the first female prime minister in India chose a peaceful way to rule her country. When her coun try was at war with Pakistan in 1971, she signed the treaty of friendship and cooperation with Pakistan to avoid financial hardship and instability in her country (Palekar, pars.  2-5).Thus, resulting a stable economy in India. She ruled her country effectively by getting moral support from all the ministers and maintaning good relationship with the other countries which helped in the economic growth of India. This would not have happened without her compromising and friendly nature. Aside from that, female politicians also are more cooperative and trustworthy than men. Research shows, women are more skilled at making people work together.This is because women are better at communicating with each other during work, they implement successful strategies thereby achieving higher results. On the other hand, men tend to excel more at bamboozling and cheating. This is proven by the studies of Rolf Kuemmerli and colleagues by repeating a game called Prisoner's Dilemma. This game involve s two people, they need to cooperate with each other to obtain a win-win situation. Studies shows that men do not cooperate as well as women because women have a better ability to interact and comprehend messages that one is trying to deliver (Highfield, pars.  5-11).In addition, women are found to be more trustworthy than men. This statement is proven by Professor Roger Steare using the â€Å"Moral DNA† test by measuring a person's morality and changes in their value system when they enter the workplace. According to results, women have more moral values , proving that they are more trustworthy (Knight, pars. 3-5). Making them better politicians. Besides that, scientists claimed that male politicians are more decisive than female politicians (Men more decisive, pars. 5-9) .However, that doesn't mean that female politicians are not good at making decisions. In fact, female politician are less decisive but more strong-minded than men as they consider their decision thoroughl y before finalizing. Before making a desicion, they examine the consequences towards an individual, society and the country and seek for a win-win solution. They search for long-term solutions by using retention strategies as a way to improve the results. Thus, they have the capacity to be more balanced in decision-making.Not only that, women are more precautious and they tend to make less mistakes in their work. This is because women always think twice and recheck their work before completing the final touches. This indirectly proves that women are better politicians than men. In my opinion, women politicians make better politicians because they compromise better, are more trustworthy and cooperative, plus they are more strong-minded as compared to men. They have more good aspects when compared to men. Thus, women are better politicians than men.

Theories of Personality Essay Example

Theories of Personality Essay Example Theories of Personality Essay Theories of Personality Essay Theories of Personality Psychoanalytic perspective is based on Sigmund Frued perspectives about early experiences it focuses on the importance of the unconscious mind which contains thoughts, wishes, feelings and memories/past experiences in which we are unaware of. The id operates on the pleasure principle by satisfying basic urges, needs, and desires. Ego operates on the reality principle, satisfies the id’s desires in ways that it will cause pleasure instead of pain. Superego strives for perfection, positive feelings and negative feelings of guilt. These three systems were interactions of Frued’s view of personality structure. Freud perspective also focused on psychosexual stages which is the childhood stages of development. Defense mechanisms are methods of reducing anxiety. This perspective could account for the development of introverted and an extroverted personality Humanistic perspective focuses on an individual’s uniqueness and their ability and responsibility to make choices in their lives. Abraham Maslow and Carl Rogers were the founders of this theory they believed that a persons free choice, free will, and understanding of their own experiences and feelings. The meanings of events in his or her life are the most important things to study. Carl Rogers believed that Human nature is viewed as basically good and that we all strive for actualizing tendencies but never reached them if based on the opinions of others. Rogers used client-centered therapy to raise the self-concept of the client and stop their tendencies to look for others opinions. The client’s esteem needs will be met and hopefully seize from concerning other people’s opinions. Rogers also developed a q-sort to judge the self-concept. The humanistic perspective can lead to an introverted personality by the individual not reaching their actualizing tendencies because of the opinions of others. The individual may base their level of self-concept on others’ opinions and if he/she receives negative opinions then that may lead the individual to have low self-esteem and an introverted personality. The humanistic perspective can also lead to an extroverted personality by the individual raising their self-concept by stopping their tendencies to look for others approval. Once they accept themselves, their esteem needs will be met and obtain gratification about themselves. Once their self-esteem rises, the individual will feel more comfortable socializing and be more energized The Trait perspective suggests that individual personalities are composed broad dispositions. The trait approach to personality is focused on differences between individuals. A trait is defined as a relatively stable predisposition to behave in a specific way. The â€Å"Big Five† is factors of personality that represents five core traits that interact to form human personality. These traits were Conscientiousness, Agreeableness, Neuroticism, Openness, and Extraversion. Psychologist, Gordon Allport believed that every individual was unique and categorized their traits in three levels: Cardinal Traits (traits that dominate an individual’s whole life), Central Traits (general characteristics that form the basic foundations of personality), and Secondary Traits (traits that are sometimes related to attitudes and often appear only in certain situations). Also British psychologist Hans Eysenck developed a model of personality based upon just three universal trails. Introversion/Extraversion: Introversion involves directing attention on inner experiences, while extraversion relates to focusing attention outward on the environment. Neuroticism/Emotional Stability: Neuroticism refers to an individual’s tendency to become upset or emotional, while stability refers to the tendency to remain emotionally constant. Finally there is Psychoticism which is having difficulty dealing with reality and may be antisocial, hostile, non-empathetic and manipulative. The trait perspective can lead to an introverted personality by having psychoticism that perhaps consisted from a genetic basis. An individual might have inherited psychoticism, thus leading the individual to have interpersonal hostility and an introverted personality. The trait perspective can lead to an extroverted personality by having Extraversion traits as the individuals Cardinal traits. The individuals attitude would be sociable, fun-loving, and affectionate, plus all that will be their dominate traits, thus having and extroverted personality. Introversion involves directing attention on inner experiences, while extraversion relates to focusing attention outward on other people and the environment. So, a person high in introversion might be quiet and reserved, while an individual high in extraversion might be sociable and outgoing. The social cognitive perspective was proposed by Albert Bandura it emphasizes the interactions of a person and their situations. Social cognitive theorists focused on how we and our environment interact they believed we learn many of our behaviors by observing others as well as mental process which was thinking about our situations affects our behavior. A. Learned Helplessness- Learned helplessness is when people and animals experience no control over repeated bad events and then come to feel hopeless, helpless and depressed. An example of learned helplessness is a person with low self esteem, they start to feel hopeless and depressed when they think someone else is better than them whether they are better looking, or better at doing something they begin to let there guard down and then feel depressed and hopeless. Optimistic Attributional Style- A positive or negative way of explaining events in their lives. A person may say that a positive event happened because of them and they also believe that more positive things will happen in the future due to that event. As for negative events they see them as it not being their fault. An example would be External Locus of Control- The perception that chance or outside forces beyond one’s personal control determine one’s fate. Individuals who have no self-control are external locus of control. Self- serving Bias- is a readiness to perceive oneself favorably. It refers to attribute positive outcomes to personal factors, but attribute negative outcomes to external factors. An example would be if you won your first track meet, you might say that this was due to the fact that you practiced hard, or that you’re a fast runner. If you lost, you might blame the referee, the weather, or the fields where you are competing rather than admitting that you did not do your best. Psychology

Counterintelligence essays

Counterintelligence essays As far as intelligence organizations, intelligence designates information that is gathered by these governmental agencies and used for purposes of national security and foreign policy. The US Intelligence Community is comprised of sixteen agencies but the total number of security and intelligences agencies is much larger covering an impressive number of possible threats to national security; it included the Central Intelligence Agency CIA an independent organization. Thesis: Intelligence responsibilities need to be shared by multiple agencies because different threats require different approaches; this would also prevent prevailing partisan influences. Intelligence agencies are governmental thus political tools for shaping foreign policy and for homeland protection hence they are subject to the process of specialization. Specialization is a concept which is applied to science; it allows close study of problems and theories; its downside is that it focuses the attention on a single area of study which in turn, limits valid perspectives in other areas which might influence our area of interest. Specialization is needed not only in the academic field but also for its contributions to public discourse and policy1. Intelligence techniques are utilized both during war and peace for a wide range of foreign policy functions, from espionage to political assassination. In the case of public policy making, decision makers apply one instrument in a set of cases based on estimates of likely effects. The governmental function of intelligence agencies are normally shrouded in secrecy. As far as foreign intelligence, it implies understanding past events, analyzing current conditions, and thus attempting to predict the future. This predictability is crucial to intelligence agencies whose mission is to gather information, provide a coherent analysis, and cooperate with other institutions. Some voices are quite critical of the way in...

A continuous budget remains more relevant and more current. As a service company, â€Å"Cleaning Services for London† the operating budget includes purchase budget, human resources budget and sales budget. One of the major facets of budgeting is cost control. Budgets are the key to cost control. The purpose of budgetary control is to help master the financial aspects of the company’s operations and solve problems before they occur. Financial control is exercised by managers in preparing budgets for revenues and expenditures of an organisation in advance. Budgetary control facilitates the management and allocation of resources and funds in operating the business to achieve desired outcomes or to provide basis for revision of business objectives and plans. The activities of the company are categorized into two – revenue generators and cost drivers. These main activities summarise the operations of the company in financial terms where revenue generators are cash inflow of the company while cost drivers are expenses incurred in the operation of the business. The company utilises a simple budget system in line with a business plan for one year. The manager who is responsible for the financial, marketing, administrative and operational matters uses cash flow forecasts as basis

Strategic and Financial Decision Making Essay Example | Topics and Well Written Essays - 2000 words

Strategic and Financial Decision Making - Essay Example The cost of financing through equity is more than that of debt. The bond holders are paid fixed rate of interest every year, hence they bear no risk. The equity shareholders do not receive any fixed income every year; it is dependent on the profits of the company. Hence, there is a risk involved in holding equity shares as compared to debt capital. Therefore the equity shareholders require more return as compensation to the extra risk borne by them. On the factors discussed above, debt financing would seem more attractive as compared to equity financing. But decision cannot be made solely on the cost factor. One also has to look into the risk involved in different sources of financing. Since there is a fixed obligation every year towards interest payment, it is considered to be more risky than financing through equity on which no risk is involved. Thus, a company has to decide upon the level of debt on the basis of the risk it can undertake. Eugene, Houston (2007:1).The following ste ps involved in decision making process are: Existing capital structure: One has to evaluate the existing capital structure. In case the company has too much debt already it is not advisable to issue more debt. It can also maintain the existing debt equity ratio or change the ratio. Dividend payout policy: The dividend payout ratio should be decided be the firm, so as to maintain the same every year. This is because fluctuating dividend payout ratio would reduce the confidence of the shareholders towards the company. Effect of return: The company has to analyze the effect on return because of the cost of capital. It has to ensure that it is able to earn the desire level of return of the investors. Effect of return: In order to reduce the cost of the capital a firm might take debt equity mix. However, it should first analyze the risk involved in using debt as a source of capital. Effect on cost of capital: The effect of desired level of debt and equity on the cost of capital of the company should be evaluated. Excess debt can lead to increase in cost of capital after a certain point of time because of the high risk involved. These decisions should be based after careful study of the market. The risk appetite, the required rate of return of the shareholders, the effect on market value of the shares due to change in the capital structure of the company should be studied. Hence, these factors have to be taken into consideration in order to arrive at a sound decision. b) The investment proposal involves an initial investment of 3,000,000 along with cost of forecasting of 100,000. The proposal is expected to be financed at the existing debt-equity ratio of 2:3. It is assumed that the return required by equity investors is 10.5% (real). Therefore nominal return (inflation adjusted) expected would be 10.5% + 5% (inflation) that is 15.5%. The rate of interest payable on corporate bonds (debt) is 6% p.a. We have to now compute the weighted average cost of capital
