The Six Steps in Decision Making an Example of the Topic Psychology Essays by

The Six Steps in Decision Making by Expert Ellah PHD | 23 Dec 2016 The decision making process is an integral part of the daily living. Harrisons six steps in decision making process consist of, setting the objectives, searching for the alternatives by means of scanning the organizations internal and external environment for information, comparing and evaluating alternatives by formal and informal means, practicing the arts of choice or the time when an action line is being selected from a set of alternatives, implementing the decision after choices was being renovate from the notion into a real operation and ensuring that the implemented decision in an outcome set in the first stage through follow up and control in keeping with the objectives. Need essay sample on "The Six Steps in Decision Making" topic? We will write a custom essay sample specifically for you Proceed The first step is to set the objectives. Setting objectives is important for it encourages the chapter to follow good management practices, solidifies the leadership team, focused the company on a specific aims, establishes accountability, motivate staff to achieve their sets of objectives and provides a common direction for the members. All of the companies are encouraged to set their objectives and a clear statement of the kind of service they want of achieve. For example, company objectives for IT business Industry: Objective set to achieve a certain level of market share within a specified time, the companies target is to obtain 5% market share on the industry of IT by the year 2010. Another example, ITS supports professional development for staff, the specific objective will be ITS would offer project management and introduction to ITS classes having the goals of about 80% staff will be trained by June 2008. Before you begin to collect evidence of learning outcomes, you must be able to answer the following questions: Why are you seeking this evidence, what kind of information will you collect, who will collect it, when will it be collected, how to use the results to improve what you do? Next step is the search for the alternatives by means of scanning the organizations internal and external environment for information. Internal factors that influence the scanning activity recognized as being the inpidual nature of information consciousness. External factors where identified as the cause of change in the environment. Environmental scanning foe internal and external use for information is the use of information about trends, events and relationships in the organizations internal and external environment that would help the management in planning the organizations future course of action. Organization need to recognize that major changes for a variety of reasons may happen on the company, including fear of the unknown, inadequacy to deal with the change and whether the change will result in an adverse effect on their jobs. Alternative actions that are appropriate to the problem should be identified. The more time and effort should be devoted in searching and developing the alternatives to a more important problem to be solved. The knowledge that decision makers have is sometimes limited by their beliefs, attitudes, values, educations and incomplete information. For this reason, decision makers accept the first satisfactory alternative they uncover, rather than maximize or search until they find the best alternatives that would be beneficial for the future run. For example: the process technologies and the people used in handling and purchasing information, data collected point to an average of 50% staff involve handling the companies information from the little to the big ones. Another example is when the companies are tending to act under request companies going to its crisis, companies tending turning inwards to reorganize. Organizations by means of scanning internal and external environment for information will be able to build satisfactory, creative and innovative alternatives for the problems that the company is facing. Thirdly, compare and evaluate those alternatives by formal and informal means. A comprehensive alternatives evaluation process can help business and organizations find a safer substitute or alternatives to their existing service use up to a more innovative solution to alternate that satisfies them. Comparing those alternatives by means of an established mode or a formal means and informal may bring them to the extent of creating and having the best alternatives which best suit the service and program. This assessment also provides a tool to assist business as they work toward creating a better workplace. Alternative assessment also helps companies plan strategically and anticipate regulations to avoid future cost and problem while meeting their high expectations. At the time when the action is being selected from the given sets of alternatives the fourth step by then is practicing the arts of choice. Practicing your alternative choice is the next target for the efficiency and effectiveness of the business, for practice is one great way to get better. Practicing includes setting the priorities and goals such as how efficient you want your company be and how time you can put to make you be more focused. This phase includes creating a readiness for change in your client organization and developing approaches to overcome resistance to change. The vision should clearly depict how the achievement of the vision will improve the organization. For example, if a company wants to advertise their products, there are several options that they can choose from such as through the net or by television or newspaper. In the third step, it is important to important to evaluate these options regarding affectivity and as well the cost. In the fourth step, the company will act and bring the chosen action into reality. The company may also try to endorse their product through all the alternatives listed and then decide which one will benefit the company the most. These steps are important to inpidual as well. Take for example a teacher. In order to increase the learning of the students, the teacher will think of alternatives and different ways of teaching and other activities and initially predicts the outcome of each teaching method. This is done in step three. Next, the teacher will then used all of the listed method and assess the effects of each one to the students in order to come up with the conclusion of the best method that is supported by evidences. The fifth step in decision-making process is the implementation of the decision after choices was being renovated from the notion into a real operation. Until some decision are taken into action this decisions are valueless. In implementing the decision to the real operation it must first define steps in implanting the decision including its timeframe for completion and also, by defining the method for reporting when something is completed and who receives the report. There are five steps in order to implement decision; first step is making an action plan. When developing a plan to implement the decision they have to understand first, the reasons for that specific decision. The overall analysis of the task, which determine the actions need to be taken and the way in which the decision process shall be implemented. Secondly is to delegate actions, some decisions are simple and easy to handle, but others may seem so complex and that may need a number of task and a working team, delegat ing those team into an assigned task and responsibility makes the job a lot easier. Third, communicating a decision, after the decision has taken and planned it needs to be relayed directly and indirectly by the affected. When they communicate and clearly explain the decision made and action to be taken it will remove uncertainty and objections from the mind of concerned parties. Fourth, discussing the progress of the decision, many meeting may have no purpose but inform, meetings are specifically held to discuss progress in the implementation of the decision. Dont waste time. And last but not the least, overcoming objections, rather than feeling aggrieved, opposition should be viewed as a valuable part of decision-making, ignore objections that may only result into misunderstanding. Take for example an organization that wants to get its product on the web; this decision to widen their scope is done in the strategic level. Next, the idea is implemented in the web that is done in the tactical level. In the operational level, the web site is supported on a daily basis. Thus, each level has its own role in fulfilling the companys objective and different things are expected from different levels in order to support the IT infrastructure. The sixth and the final step in decision making process is ensuring that the implemented decision in an outcome set in the first stage through follow ups and control in keeping with the objectives. This is essential to test and ensure that the company meets its desired goal and functions. Example: the company has to build follow team and conduct some research to prove the effectiveness of the service and see it if meets their goals. Proposed a set of principles for follow up activities and must discussed it in a more detailed way the t all the members may have clear audit on it for the development of the policy guidelines. Follow ups included major subject matters such as issue, scale and timing, frequency and power, roles, functions and the principle. Its role must to control function for the purpose of evaluation.

My Box and Valentine Essays

My Box and Valentine Essays My Box and Valentine Paper My Box and Valentine Paper Essay Topic: Carol ann Duffy Poems Poetry My Box by Gillian Clarke is a poem about a box a lover produces himself for his lover. The box symbolises the couples relationship and memories as in my box are twelve black books, where I have written down how we have sanded, oiled and planed The box symbolises the memories and the joyous day they shared together. Although the lover has made the box, it has been created by emotions, feeling and love. The box becomes the romantic image within the poem. In this box are stored memories of the couples relationship. At the end of each stanza, the poet refers to a golden tree. This golden tree plays a significant part in the poem, as it reflects the solidness of their relationship. The tree represents the building and growing up of a beautiful relationship having the branches representing the ups and downs of their time together. Valentine on the other hand, has a far stranger meaning of love than My Box. The title tells you that the poem is a valentine a gift of love but straight away the poem makes it clear that it is not an ordinary type of valentine not a red rose or a satin heart, rejecting conventional presents, as she gives an onion. It seems rather strange that someone would give their lover such a worthless gift. However, when we realise what the onion symbolises, we understand that it actually is the perfect gift. The poet uses an extended metaphor. She writes about her relationship as if it was an onion. For example It is a moon wrapped in brown paper. It promises light This reminds us of the papery, brown skin of an onion, and the moist, shimmery moonlight glow of an onion when it is freshly peeled. Love is often associated with moonlit night, so this is a romantic statement. The onion is wrapped in brown paper, suggesting that her love is pure and simple; therefore the onion can say all she wants to say to her lover. It is interesting that where other poets might talk about their feelings for a lover using symbols, this poet uses a symbol to talk about her love. A brown paper wrapping has to be removed. So does the onion skin. When the different layers of the onion are revealed they are like the careful undressing of love, that is, the discoveries that love brings. In My Box, however, a similar picture is drawn, as the golden tree takes time to grow, it has to be nurtured, fed and looked after just like the relationship. Carol Ann Duffy makes you more aware of the poem by using an unusual image- it makes you curious therefore it persuades you to carry on reading. The poem shows how normal valentine gifts do not necessarily have to show you love someone. That is why she uses an onion to prove her point. She argues that an onion is a good symbol of the relationship she has with her partner. My box is more rural referring to harvested apples, gold crests and rare red kites, where as Valentine uses simple words and language. Both poems portray a picture of how the present symbolises love- both in a positive and romantic attitude. My box is made of golden oak, is the first line to My Box she tells us how her box is made of oak which is solid wood, suggesting the stability and strength of her own relationship. Valentine explains how an onion is a moon wrapped in brown paper and how it promises light, like the careful undressing of love. The poet creates a sexual yet delicate image in these lines sexual by the word undressing, yet delicate created by the word in front of it careful. In the first stanza of My Box, the poet stresses how beautifully the box has been made how the lover fitted hinges and a lock of brass and a bright key. She explains how he made it out of winter nights, sanded, oiled and planed, this box making it seem as though it took a long time to make it, and creates the box to be very precious to the woman. In the second stanza, she discusses some of the things they have achieved throughout long years of their relationship. She has written this all down in her twelve black books and keeps this in the box. In the last stanza, the woman wants her lover and/or people after her to come and read all of this- I leave it there for you to read or them when we are dead, e.g. good relationships, golden trees are slowly made in other words they dont come easily but have to be nurtured and worked out. Both poems explain how love is everlasting the golden tree represents the purity and value of love and the onion represents how you have to peel each layer of your lover to reveal a layer of them. The poet adds a note of caution too much commitment could kill off their relationship- Lethal. The vocabulary used in My Box is connected to nature- nature representing their love and feelings, where as Valentine uses words describing the onion, or words that are connected with love to the onion. The language and vocabulary is very simple perhaps to suggest that she wants a simple, uncomplicated love. She makes statements I give you an onion it will blind you with tears. They make the poet sound definite and authoritive. Carol Ann Duffy gives you the message that an onion is more than a soppy card or a cute teddy. My Box on the other hand is more conventional and explains how in my box are twelve black books- how we have sanded, oiled and planed the relationship. Gillian Clarke places her words in threes sanded, oiled and planed seen jays and gold crests, rare red kites harvested apples and words and days. The repeated structure of and emphasises what is going on. It is important to notice the spaces between the stanzas in Valentine. For example it is interesting that I am trying to be truthful is a statement on its own, (to emphasis how vital truth is in a relationship) but is followed by not a cute card or a kissogram. The second pause allows us to reflect that cute cards and kissograms (more usual valentine gifts) dont really reflect true love. In My Box, the beats in a line are regular- 8,6,8,6 etc, as are the lines. This suggests that she wanted her poem to be solid like her golden tree. Carol Ann Duffy uses a lot of I/you structure in Valentine. The I is the speaker and the you is the recipient of the onion. This allows Carol Ann Duffy to construct something like a one-sided dialogue. In My Box, Gillian Clarke also uses I, but she also uses we- referring to the couple, not just an individual. If we think of the metaphors for Valentines Day; the roses, satin hearts, and cute cards, it is clear to us by now that Carol Ann Duffs intention is to eliminate the pretty image of Valentines Day to make people realise that love is serious. Take it. Line 18 tells us that you have not taken the onion yet. The second offer of the onion takes us to the final stanza, where more metaphors are found. Its platinum loops shrink to a wedding-ring. The poet used platinum taking a deliberately unromantic view. The speaker goes for the plainer look metal, but one of worth. The ring inspired by the onion is offered with if you like. The person to whom the whole onion is given to is offered the choice. There is no promise of hearts and roses. Lethal. Usually this word is linked with danger and deadly, yet it is used in the poem. The speaker cautions the recipient- that too much commitment could lead to the breaking off of their relationship. Most of the poem sounds as if the lines are natural and spontaneous, being written as the words came to her because there is no rhyme in the poem. However, some of the sounds are carefully arranged. Its fierce kiss will stay on your lips. The s sounds may suggest a couple kissing. I give you an onion is repeated it reinforces that it not a joke, that she is giving this person an onion and really means it. The poem does not have a regular beat or form as My Box. The lines and stanzas are of irregular length. This could be to give a sense of urgency, or that because traditional poems are often written very regular and may even rhyme, her decision not to confirm to this stereotype is further proof that her love goes beyond the ordinary, and so is that much more special. The tone of the poem is sad and negative, warning her lover not to get too close, yet realistic, but encouraging and warm. My Box has a warm and encouraging tone to it it is gentle and tender.

Mathematics and statics for economists - Statistics Project Example The sample data for happiness is positively skewed which means that most people interviewed has a positive happiness level. The kurtosis of 15.41579212 shows that the probability of extreme values is less than for a level of happiness, and the values are wider spread around the mean of 4.820680628. The histogram gives a clear graphical representation of positive kurtosis and skewness. The data are concentrated to the left of the mean level of happiness representing a general positive level of happiness among the sample population. In a nutshell, the data is positively skewed but with a median of 5, the data is almost normally distributed considering that the mean is 4.820680628. From the Anova results above, the P value 0.00 while the significance level ÃŽ ±=0.05. The P value 0.00 The correlation results show that level of happiness and means of traveling to work exhibit a positive association. The correlation coefficient is 0.819346. This happiness and means of travelling travel in the same direction. The regression equation shows the relationship between happiness and means of travelling travel in the same direction. According to the regression line, an increase of means of travelling to work by one unit will increase the level of happiness 2.740298 when all factors are held constant. From the regression result, means of traveling to work positively influence the level of happiness. This means the two variables exhibit a positive relationship. The results according to the link above show that there effects of commuting to the level of happiness at

The role of the secretariat of the United Nations Research Paper

The role of the secretariat of the United Nations - Research Paper Example 1-3). The secretariat is the backbone of the UN structure, which performs numerous, diverse and wide-ranging tasks, and duties that include supervision and management of international operations, carrying out surveys regarding the economic and social trends of different nations. Additionally, the secretariat oversees and governs the activities and policies designed by the G.A. It also acts as a communicator that clarifies the communication media concerning the activities of the UN, and thus it is divided up into various offices and departments (Myint-U,  Scott  & International Peace Academy, 2007, pp. 1-6). In this regard, it becomes important to carry out research to discover the vast responsibilities and impact of secretariat of the United Nations. Hence, the purpose of the research proposal is to study "The Role of Secretariat of the United Nations", as the role of secretariat in the United Nations is one of the considerable aspects that need to be measured. The study aims to analyze, explore, and investigate the functions and responsibilities of the secretariat of the United Nations. Therefore, with this fundamental objective, an empirical study would be carried out that would incorporate the primary and key features with respect to the secretariat’s role: The research methodology is the systematic approach that would come under performance in order to collect and accumulate the widespread data and then convert into valuable information with reference to the aims and objectives of the study. Therefore, considering the question of the secretariat of the United Nations, the researcher would implement the secondary research methodology as the fundamental source to collect information (Kothari, 2008, pp. 1-5). The secondary research methodology helps the researcher to gather a wide range of information that is available through a number of sources that include publications, reports, databases, and historical evidences.

Evidence-Based Practice Paper and Intervention Presentation on Essay

Evidence-Based Practice Paper and Intervention Presentation on Diabetes (Benchmark Assessment) - Essay Example Primarily, DM diagnosis relies on the measurement of plasma glucose levels. This diagnostic mode is effective in detecting diabetics and pre-diabetics, but it does not offer a clear mode of assessing resultant complications, which often start in the vascular system. The diagnosis therefore, only tests tolerance to glucose, and not the associated risks such as the vascular risks (Pavri, 2001). The further assessment of risk may be necessary in monitoring the condition and administration of treatment, but it has not been available. However, a recent research by Zampetaki and others has led to the discovery of biomarkers that can be used in diagnosing and monitoring type II diabetes and its associated risk (Zampetaki et al., 2010). Description of Diagnostic Tool The new diagnostic tool uses microarray screening and real-time polymerase chain reaction (PCR) processes to monitor MicroRNAs (miRNAs), which have been positively associated with the development of the condition and its progres sion. This new tool offers significant prognostic ability to predict and monitor type II DM. The miRNAs are small group of RNAs not involved in coding. They instead work as repressors in translation (Zampetaki et al., 2010). The miRNAs bind to complementing sites by base pairing on untranslated portions of the target mRNA. They are responsible for directing repression or degradation of the transcripts. Research has shown that miRNAs influence stress responses, oncogenesis, development and angiogenesis. They also play a significant role in endothelial cell functioning as well as the regulation of angiogenic potential and inflammations. The study found that miRNAs change prior to the start of type II DM (Zampetaki et al., 2010). The changes were narrowed to miRNA-126, which was found to profoundly change with type II DM (Larkin, 2010). This provided proof for a plasma Micro-RNA signature for patients with type II DM, thus suggesting a possible prognostic value in monitoring and diagno sing DM (Zampetaki et al., 2010). Summary of Research The study on miRNAs and DM was part of a wider Italy-based Bruneck Research on various conditions including cardiovascular diseases. The study was initiated in 1990 by â€Å"King’s College London British Heart Foundation Centre (Larkin, 2010).† The researchers sampled and measured miRNAs from a total of 822 participants. Some of the participants had type II DM, whereas; others were controls. The measurements were conducted in five phases on an annual basis from 1990 to 2005. The use of microarray screening and real-time PCR identified 700 miRNAs. The researchers then used miRNA relevance network inference technique to understand the miRNAs regulatory networks. The technique revealed changes in the levels of some five miRNAs prior to the start of type II DM. Notably, miRNA-126 was found to show a consistent decline, which was correlated to the incidence and prevalence of type II DM (Zampetaki et al., 2010). The fact that miRNA-126 is significant in wound repair and vessel health implies that its decline is an indicator of vascular risk levels associated with DM. miRNA-126 is rich in normally functioning endothelial cells and its decline associated with DM may be an indicator of the progression of deterioration caused by DM, which increases vascular risk (Zampetaki et al., 2010). As such, miRNA can be a significant prognostic tool in monitoring DM and associated risks (Larkin, 2010). The study

Xenobiotics Metabolizing Enzymes Very Important Exogenous Endogenous Compounds Biology Essay

Xenobiotics Metabolizing Enzymes Very Important Exogenous Endogenous Compounds Biology Essay Xenobiotics metabolizing enzymes (XMES) are very important for metabolizing of exogenous and endogenous compounds [23]. They are involved in the biotransformation of exogenous compounds like procarcinogen, drugs, solvents. They are categorized into parts: phase I and phase II enzymes. Cytochrome 450 family comes under phase I enzyme. Cytochrome P450 family of enzymes is mainly involved in synthesis and metabolism processes of exogenous and endogenous compounds. CYP genes are located mainly in the liver and within the cell are present in the endoplasmic reticulum and also in the mitochondria. CYP family is divided into four main families: CYP 1, CYP 2, CYP 3 and CYP4. CYP has two main roles in the human body [24]. First, CYP is used by the body to metabolize and transform a range of hydrophobic xenobiotics (exogenous, foreign compounds such as pesticides, carcinogens, and pollutants) to more polar metabolites so that they can be readily excreted in the urine. By biotransforming potentially toxic compounds to less potent forms, CYP works as a natural detoxifying agent of the body. Large populations of CYP are found bound to the endoplasmic reticulum in mammalian liver cells, the primary site of metabolism. The gene families most commonly found in humans and involved in metabolism include cytochrome P-450 1, 2, and 3 (known as CYP 1, CYP 2, and CYP 3). Second, CYP enzymes are used in the synthesis of important signaling molecules, such as steroid hormones in the endocrine glands, fat-soluble vitamins and Metabolism of fats (cholesterol and fatty acids). CYP metabolisms have adverse effects as well as beneficial effects. CYP plays an important role in activating carcinogens, such as polyaromatic hydrocarbon (PAH), by an oxidation mechanism. They are also involved in the metabolism of certain medication that are ingested (endoplasmic reticulum) and also certain toxin/internal substances formed within the cells (mitochondria). These functions mainly depend upon iron present in it as a prosthetic group. Hence, they are called hemoproteins. Iron contains two 4s electrons and six 3d shell electrons in its valence shell. The function of this gene depends on the shifting oxidation state of iron between ferrous Fe2+ (loss of the 4s electrons) and ferric Fe3+ (loss of an additional 3d electron). As the ferric state results in a half-filled 3d shell, it is the more stable form of the two states. As a result, CYP can be readily reduced with the addition of an electron. It is a group of heme-thiolate monooxygenases and involved in an independent NADPH dependent electron transport pathway [24]. Fig1. Metal complex structure of CYP 450 5. MECHANISM 5.1. CARCINOGEN IDENTIFICATION The carcinogen from tobacco smoking is genotoxic carcinogens that are capable on inducing DNA lesion. This carcinogen is divided into two parts, first is direct carcinogens and second is procarcinogens. Direct carcinogens are highly reactive and having an electrophilic groups with surplus positive charge. They interact directly with DNA and form DNA adducts. The example of this carcinogens are N-nitrosoalkylurea, ethyl- and methylmethanesulfonate, N-methyl-N-nitronitrosoguanidine, sulfur mustard, diepoxybutane, beta-propiolactone, ethyleneimine, etc. Initially, procarcinogens are chemically in inactive form. When procarcinogens go inside the body, they interact with different types of enzyme that metabolise in the cell in two steps. In the first step, procarcinogen are activated and converted into electrophilic derivatives. In the second step, the metabolic products are neutralized by conjugation. The first step process is mainly done by CYTOCHROME 450 family and second step process is done by conjugating enzymes include acyltransferase, epoxidases, sulfotransferases, glutathione-S-transferases, UDP-glucuronyl transferases, and transaminases [6]. They are activated by oxidation process that is mainly done by CYP gene. The main procarcinogen in smoking that create negative effect on CYP1A1 genes are mainly polycyclic aromatic hydrocarbon group (Benzo(a)pyrene, Benz(a)anthracene, Benzo(b) fluoranthene, Benzo(c)phenanthrene) and N-nitrosamines (NNK) [8]. CYP1A1 does not form directly tumour, it only makes procarcinogen to carcinogen that forms tumour formation. Cytochrome p450 enzyme comes under the phase1 enzymes which convertes the mutagens to epoxides in the K-region as well as the Bay region of Benzo (a) pyrene [1]. CYP gene carry out oxidation and reduction of the hydrophobic ligands converting them into epoxides usually in the K-region which is then taken up by phase2 enzyme (GST) and metabolized into water soluble compounds (later excreted through urine). But if the epoxide is formed near the bay region then phase2 enzymes become idle without carrying out any metabolic process. The CYP gene metabolises the carcinogens to epoxides, which are highly reactive and binds to DNA and further activate d to diol epoxides. They covert the carcinogen B[a] P into B[a]P-7,8-diol-9,10-epoxides which has got high DNA binding capacity. These mutagens are termed as Bay epoxides as they have tumourogenic effects on DNA. The presence of motif reason of CYP 450 oxidizes the PAH. The motif reason of CYP450 is Phe-X(6-9)-Cys-X-Gly, where X is a specific amino acid. Cysteine binds to heme iron and takes part in the transfer of one atmospheric oxygen atom to the substrate that contained in the pocket of the substrate-binding site in the enzyme active center. In few cases, the life span of metabolites is very short (several milliseconds) due to their high reactivity and fast conversion into stable hydroxylated derivatives. In other cases, due to slow decomposition of metabolites they easily enter into the nucleus, mitochondria, and other cell organelles. The reaction catalyzed by cytochromes P450 is a monooxygenase reaction, e.g., insertion of one atom of oxygen into an organic substrate (RH) whi le the other oxygen atom is reduced to water: RH + O2 + 2H+ + 2e- → ROH + H2O Fig2. Substrate oxidation in the cytochrome P450 system Fig3. Bay and K region of Benzo(a)pyrene and epoxide formation of Bay region Fig4. Epoxide formation of B(a)P 5.2. INDUCTION OF CYP GENE The amount of CYP1A1 is responsible for tumour formation in organs. Basal expression of CYP1A1 is negligible. High amount of CYP1A1 increases the risk of tumour formation or cancer. It can create an imbalance condition between detoxification and activation that leads to adverse effects. It converts the procarcinogen to carcinogen by oxidation process. At high substrate concentrations detoxification becomes saturated and induction can increase the production of reactive metabolites compare to the capacity of cellular defenses, thereby producing toxicity or neoplasia [9]. Procarcinogen increases the amount of CYP1A1. CYP1A1 is induced by two pathways namely canonical and non-canonical signaling pathway of AhR. Canonical signaling pathway enhances the synthesis of CYP1A1 that causes tumour formation. There is no evidence to prove that Non-Canonical signaling pathway is the reason of tumour promoter. Our study show that the research is going on about non canonical signaling pathway. CYP1A1 is also called as AHH (Aryl Hydrocarbon hydroxylase). It is involved in the metabolic activation of aromatic hydrocarbon (polycyclic aromatic hydrocarbons). The studies on the mechanism revealed that ligand like B[a]P binds to the receptor AhR (aryl hydrocarbon receptor) (an intracellular protein that starts the induction process by biding inducer) in the cytosol. When B(a)P goes inside the body, it will pass through lipid membrane before reaching the cytosol. It is a hydrophobic as well as lipophilic compound that accumulates in the membrane of lipid bilayer, So that the membrane loses its reliability and an increase in permeability to protons and ions. Therefore, it creates imbalance the proton motive force and intracellular pH. In addition to the effects of lipophilic compounds on the lipid part of the membrane, proteins surrounded in the membrane are affected. The effects on the membrane-embedded proteins result to a large extent from changes in the lipid environment [7, 9]. So that PAH is able to go inside the cytosol and makes complex with Ahr receptor. Usually the AhR receptor is present as a part of the cytosolic protein complex which includes 2 hsp90, p23 and XAP2 or AIP (also known as co-chaperons). Once the ligand is bound to the receptor, the co-chaperons dissociate and the receptor is translolcated into the nucleus. This complex along with the ligand molecule heterodimerizes, with another molecule ARNT (AhR nuclear translocator). This heterodimer binds to the consensus regulatory sequences such as AhREs (Ah responsive elements), XRE s (Xenobiotics responsive elements) or DREs (dioxin responsive elements) to be found in the promoter region of AhR target genes such as CYP1A1, thereby initiating the transcription by RNA-polyII [1]. The transcription of CYP1A1 gene is inhibited by AhRR protein .The AhRR/ARNT heterodimer stops the transcription process initiated by XREs and also inhibits the heterodimer formation of AhR-ARNT [2,1]. Fig.5. Canonical signaling pathway of AhR 5.3. ALTERATION IN CYP1A1 Mainly four types of polymorphism happen in CYP1A1 that enhances the tumour formation in organs by increasing the oxidation process that makes procarcinogen to carcinogen. These four polymorphisms [19] are as follows: M1 (Msp1), T→C substitution at nucleotide 3801 in the 3-non-coding region. M2 (Msp2), A→G substitution at nucleotide 2455 leading to an amino acid change of isoleucine to valine at codon 462. M3, T→C substitution at nucleotide 3205 in the 3-non-coding region. M4, C→A substitution at nucleotide 2453 leading to an amino acid change of threonine to asparagine at codon 461. These mutations do not happen due to smoking; it can lead to enhance the more AHH (aryl hydrocarbon hydroxylase) activity. Each mutation has different function and plays an important role in the tumour formation. For example, CYP1A1 Msp1 (M1) increases the catalytic activity and CYP1A1 Msp2 (M2) is directly related to other functional polymorphism and creates more PAH-DNA adducts in white blood cells [30]. This mutations happen mainly in lung, larynx, pharynx, oral, breast, ovary, liver, colorectal and esophagus. The mechanism of CYP1A1 is same for all organisms and the formation of tumour in these organs depends upon geographical factor, demographic factor and number of cigarettes. Lung cancer In lung cancer generally Msp1 (T→C) mutations occur, but in Brazil Msp2 (A→G) mutation associates with lung cancer [17, 19]. B(a)P and NNK carcinogen mainly involve with liver cancer. Oral cancer, larynx and pharynx Msp2 and Msp1 mutation also associates with oral cancer, larynx and pharynx [15, 16, 18]. And PAH and NNN are associated with these cancer. Benzo[a]pyrene, NNN and NNK are carcinogens that enhance the oral cancer [29]. The studies of various articles show that CYP1A1 Msp1 (M1) mutation maximum associates with increasing the risk of oral squamous cell carcinoma. Breast Cancer CYPIAI (M1) and CYP1A1 (M2) increase the risk of breast cancer [20, 21].PAH forms PAH-DNA adduct in breast tissue that associates with increased breast cancer. Generally PAH is used for the study of tumor formation in breast cancer because of three reasons, first it is a good model for understanding the chemical mechanism of tumour formation by chemicals. Second the geometric resemblance of PAH and endogenous estrogen is same. Third estrogens and PAH have aromatic ring. PAH are activated by two pathways, first by electron oxidation and second by CYP1A1. DNA adducts are formed by metabolically activated PAH binding with the nucleophilic groups of the two purine bases, adenine (A) and guanine (G). Both adducts may be either stable or depurinating (It is the loss of purine (adenine or guanine) from DNA backbone). The stable adducts is formed by covalently bonding to DNA unless removed during repair, where the depurinating adducts are those that are released from DNA by deterioration of the glycosidic bond .Stable DNA adducts are created when PAH binds with the exocyclic amino group of A or G, where depurinating adducts are formed by covalently bonding of PAH at the N-3 or N-7 position of Adenine or the N-7 or, sometimes, the C-8 position of Guanine [26, 27].

The American Dream in Death Of A Salesman, by Arthur Miller Essay

Success: Accomplishing Your Dream Completing the "American Dream" is a controversial issue. The American Dream can be defined as having a nice car, maybe two or three of them, having a beautiful, healthy family, making an impact on the world, or even just having extra spending money when the bills are paid. In the play "Death Of A Salesman," by Arthur Miller, the "American Dream" deals with prosperity, status, and being immortalized. Willy Loman, a hard worker aged to his sixties never accomplished this goal. He always talked the talked, but never achieved to walk the walk. Willy Loman would always talk about who he's met and how he has always well known and liked, but truthfully he never was. "Willy: He's liked, but not-well liked†¦I got on the road and I went north to Providence. Met the Mayor. (ACT I, lines 232, 234)†¦Willy: And they know me, boys, they know me up and down New England.

The benefits of a well designed flat tax

In an effort to salvage our economic system, the earned income revenue enhancement rate for all U.S. taxpayers will be 18 % . A good designed level revenue enhancement would non merely cut down conformity and administrative costs but it would besides heighten productiveness and work inducements. In altering the revenue enhancement rate to an 18 % revenue enhancement payment program, it sets a standard payment rate for everyone alternatively of multiple revenue enhancement brackets and has the possible to cut down our state ‘s debt. The current U.S. revenue enhancement system consists chiefly of revenue enhancements on income, paysheet, gross revenues and belongings. Harmonizing to Clemson University ‘s Holley Ulbrich, in 2007, these revenue enhancements provided 92 per centum of federal income and 51 per centum of province and local authorities income ( Ulbrich 2 ) . Therefore, since income revenue enhancement is a important beginning of funding national, province and loc al exchequers, how it is collected is really of import. For intents of discoursing this amendment, the federal income revenue enhancement is the chief issue being discussed. State and local issues may be used as illustrations, but non in a manner that has impact on the level revenue enhancement being proposed. The proposed level revenue enhancement rate for all taxpayers will hold a positive impact on the economic system by increasing the figure of revenue enhancement returns filed, the lower costs of treating them, will promote investing and concern chances, and will increase the overall income to the authorities from higher Numberss of revenue enhancement returns being filed. Implementing a level revenue enhancement would cut down conformity and administrative costs for the authorities. Since the IRS employs over 100,000 people to treat revenue enhancement returns, simplifying the filing procedure would cut down the demand for the figure of workers to treat revenue enhancement payments and returns, which would salvage the authorities money ( Pascale ) . The current system today allows the IRS to roll up a higher per centum of net incomes as people ‘s income additions, while others pay small or no revenue enhancement at all. If everyone had to pay the same sum of revenue enhancements, the procedure of filing revenue enhancements would be easier, hence more people would register and there would be lower costs for the IRS to implement revenue enhancement filings. Harmonizing to Daniel Mitchell, holding a level revenue enhancement simplifies the procedure, makes things just and is good for growing ( 1 ) . Simplifying the revenue enhancement construction would ensue in more accurate and completed returns being filed, which would take down the costs of roll uping revenue enhancements from people who do n't register revenue enhancement returns, therefore salvaging the IRS money. Since there are so many tax write-offs available under the current revenue enhancement construction, there are many people who file revenue enhancement returns but pay minimum federal income revenue enhancement. In add-on to the hapless, this applies to middle category and affluent people, excessively ( Bartlett 2 ) . Peoples who earn more money are able to pass more money, so, under the current system, things like purchasing places, charity contributions and stock investings can cut down the sum of revenue enhancement people pay. By change overing to a Flat Tax system, the lowest income earners in the United States would non be capable to income revenue enhancement, but the in-between category and wealthy would non be able to subtract their revenue enhanceme nts for their places, which could go really expensive for them. Since the existent proposed level revenue enhancement collected ( 18 % ) would be well lower than their current revenue enhancement bracket ( 28 % -32 % , for illustration ) , even losing out on some tax write-offs may non hold much impact on overall revenue enhancements being paid by householders and the wealthy. Mitchell estimates that approximately 97 % of revenue enhancement returns paid would e the same or less compared to the current system. Simplifying the revenue enhancement construction should ensue in better conformity, more accurate returns being filed, and lower administrative costs, ensuing in an overall higher revenue enhancement gross base for the authorities. Adopting a level revenue enhancement for earned income would besides heighten productiveness and investing inducements for persons and concerns. By shuting loopholes and take downing rates, the efficiency of the revenue enhancement codification could increase and make more inducements for people to put With the current revenue enhancement system, some people do n't desire to put because they ‘d be paying excessively much in revenue enhancements investings if their investings earned excessively much money. By following the level revenue enhancement, investors would hold more inducements to get down and turn concerns, every bit good as brand other investings ( Mitchell 2 ) . With a level revenue enhancement system, people will cognize the sum of revenue enhancements they owe easy and can put and salvage money more efficaciously. The level revenue enhancement encourages people to put more freely without being penalized for gaining excessively much on their investings and therefore paying higher revenue enhancements. Converting to the level revenue enhancement system could ensue in America going a magnet for investings and new occupations. Another benefit of the level revenue enhancement would be the possible to cut down the U.S. National debt. Studies show that about 5-15 % of Americans do non pay their revenue enhancements because the revenue enhancement returns are excessively hard and excessively clip devouring to fix. With this new system, revenue enhancements become easier to finish and take less clip. Converting to a level revenue enhancement would merely necessitate two postcard-sized signifiers: one for labour income and the other for concern and capital income, which is dramatically simpler than the 893 revenue enhancement signifiers presently in usage. Since the complexness of the filing procedure would be reduced, fewer people would register extensions or avoid registering wholly. This should ensue in more people registering returns and with the simpler signifiers, the processing costs should be lower, excessively. The overall impact of more people registering revenue enhancements, coupled with decreased co sts in treating the returns, should be a dramatic addition of income for the authorities, which would let the U.S. to cut down its debt, as good. The acceptance of a level revenue enhancement is a alteration to the variable revenue enhancement construction. The beginning of income revenue enhancement on persons is by and large cited as the transition of the 16th Amendment. It was passed by Congress on July 2, 1909, and ratified February 3, 1913. Throughout history, revenue enhancements were enacted as a agency to hold the wealthiest people pay for the good of everyone else ( Pascale 1 ) . The level revenue enhancement would hold more people paying equal proportions of revenue enhancement, instead than holding the wealthiest people pay the most revenue enhancements. Other states have had success implementing a level revenue enhancement plan. The first state to follow a level revenue enhancement was Estonia in 1994, merely after the prostration of the Soviet Union. The other two states that enacted a level revenue enhancement were Latvia and Lithuania. For these states, the economic growing showed important betterment and the â €Å" Baltic Tigers † became function theoretical accounts for the part ( Mitchell 5 ) . Russia besides adopted a level revenue enhancement rate in 2001, which rapidly had positive consequences: the economic system prospered, and grosss poured into the authorities. Several other former Soviet states have followed suit and hold had good consequences. As Ahrens points out 24 states now employ a level revenue enhancement but, to be just, none of them has an economic system every bit complex as the United States. At the province degree, a new survey shows that most citizens of Utah are paying less under the province ‘s 5 per centum level revenue enhancement than they did under the old revenue enhancement system ( Bernick 1 ) . While this is non a federal income revenue enhancement illustration, it merely shows that the level revenue enhancement can profit people at the province degree. Still, the statement is that rich people are paying less revenue enhancement than they had been ( at the 7 % rate ) and that they are acquiring large revenue enhancement cuts under the new system at 5 per centum. The issue with the current revenue enhancement codification is that there are infinite loopholes and freedoms that normally end up profiting those who are in higher revenue enhancement brackets.A With this new system there are no loopholes and no one gets more benefit from it than anyone else.A The level revenue enhancement construction will besides assist people cut down the complication of fixing their revenue enhancement returns.A The end is to do revenue enhancement readyings so easy that people file their returns on a postcard.A The level revenue enhancement would profit the lower income households because families would have a generous freedom based on the household ‘s size.A A household off our would non pay any income revenue enhancement until its one-year household income exceeded $ 30,000 ( Mitchell 2 ) .A Since the lower income households would fundamentally pay no revenue enhancements, the load displacements to middle category and affluent people.A In world, this is no different than how revenue enhancements have been collected throughout history – the people who can pay supply for the people who can non.A Congressman Mike Pence said a level revenue enhancement could be a â€Å" major spot of revenue enhancement alleviation: for most Americans ( Terkel 2 ) .A The level revenue enhancement would non hold unvarying benefits, but due to its simpleness, it should hold minimum negative impact on current taxpayers.AThere are several expostulations to the proposed level tax.A As Bartlett states the benefits to single taxpayers would be comparatively little – the wealthy would profit is proportionally while many in the in-between category would profit merely modestly or would even pay more taxes.A Clemson University economic science professor Holley Ulbrich besides points out † aˆÂ ¦a level revenue enhancement would switch revenue enhancement duties from the rich to the hapless, and particularly the in-between category, and e xtinguish desirable revenue enhancement inducements for retirement nest eggs, place ownership and charitable parts † ( Ahrens 2 ) .A â€Å" Further, in her ain article, Ulbrich points out that the attractive force of simpleness fells a large alteration in the distribution of revenue enhancements among the hapless, the in-between category, and the rich † ( Ulbrich1 ) .A The ground that it has been hard to implement a level revenue enhancement is because it ‘s difficult to happen a revenue enhancement rate that to the full satisfies everyone – neither raising nor take downing the overall revenue enhancement load ( Bartlett 1 ) .A Harmonizing to Dean Baker, co-director of the Center for Economic Policy Research, there seems to be no grounds that a level revenue enhancement will ensue n growing or solves any current economic jobs ( Turkel 2 ) .A Those who oppose the level revenue enhancement feel that it will be a immense load to the in-between category and tha t it will non work out any of our current economic loads.AThe U.S. authorities has many concerns with respect to roll uping revenue.A Restructuring the income revenue enhancement aggregation method to a level revenue enhancement has many advantages.A It potentially reduces the load of revenue enhancement return readying for Americans and lowers the administrative costs of treating returns by the IRS.A By doing the earned revenue enhancement rate for everyone in America 18 % and distilling the revenue enhancement returns onto postcard-sized signifiers, the procedure of revenue enhancement readying, aggregation, processing and enforcement are dramatically streamlined.A The simplified construction should increase the sum of revenue enhancements collected, cut down administrative costs, and supply better inducements for concern and investings, ensuing in a important addition of gross for the United States authorities.

Discuss Various Theories of Management Essays

Discuss Various Theories of Management Essays Discuss Various Theories of Management Essay Discuss Various Theories of Management Essay pupils explore the risk of dying unexpectedly from various causes. They start from fears they know and, by comparing them with real-life data, they recognise that their perception of risk is often driven by presentations in the media. Pupils learn how to calculate the risks involved for various activities and how these are related to the base risk of death for typical people of different ages and genders. The emphasis is on order-ofmagnitude comparisons, reflecting the variations in risk level between individuals and over time. Pupils work with real data; they deduce information about small probabilities and use measures of average and spread in real life. They also work with orders of magnitude. They learn that mathematical thinking is essential for putting risks in perspective and that the media usually focus on stories rather than on information. In or out ? Pupils consider the evidence from a photograph about whether a batsman in cricket is ‘in’ or ‘out’. The original case arose from a controversial decision by an umpire in an Ashes test match (between England and Australia) in the 1960s. Pupils use mathematics to examine the photograph to assess whether the batman was ‘in’ or ‘out’. Initially, pupils construct a simple mathematical model of the situation by deciding what variables they need to measure and what assumptions they need to make. Using this evidence, they decide for themselves whether the batsman was ‘in’ or ‘out’. As the work develops, pupils explore these measurements and assumptions in detail, allowing them to refine their initial decisions and to understand that, sometimes, there is no single right answer! Pupils revisit their models, test their assumptions and apply their model to other situations. The mathematical skills and thinking that are required emerge gradually during ‘In or Out? ’ Keeping the pizza hot Keeping the pizza hot involves building a mathematical model in the context of homedelivery pizza. Pizza home-delivery is dependent on being able to deliver pizzas quickly, in an edible condition. In Keeping the pizza hot, pupils explore ways to keep a pizza warmer for longer and the implications of doing so. Pupils are asked to help answer the questions: how long does it take a pizza to cool, how far can it travel in that time and what difference does the packaging make? Keeping the pizza hot has a number of parts which include leading pupils to move from a practical problem of a cooling pizza to a mathematical representation of a cooling curve. This is a big step and is intended to induct pupils into the potential of mathematical applications. It demonstrates how mathematics can underpin scientific enquiry. The linking of the time to cool with possible distances of travel introduces further mathematics. Although not essential, this project would work well as a cross-curricular project with the science department. r4 Â © 2008 Bowland Charitable Trust of 9 My music My music uses the interest pupils have in music as an opportunity for mathematical investigations, using pupils own favourite music tracks as the raw data. Pupils work in small groups to listen to different tracks, take measurements and then interpret and present the results. They analyse the similarities and differences between types of track, looking first at tempo and then other variabl es such as track length, highest position or number of weeks in the charts, and album sales; they can also investigate trends in music over the years. My music can work as an introduction to statistical work, including: the collection of numerical data, performing basic statistical calculations, forming and testing hypotheses, making inferences about a population, and identifying potential sources of error in data collection and calculations. Although not essential, this project would work well as a crosscurricular project with the music department. Mystery tours Mystery Tours is a cartoon-based role play. Pupils take the part of the Tour Manager of a struggling tour operator; they are asked to plan a fictitious three day trip around the UK using tools and data in the software. They then lead a ‘simulation’ of the tour and write an evaluation report. There are three groups of tourists, categorised as ‘Nature Lovers’, ‘Thrill Seekers’ and ‘Culture Vultures’; data is available about the preferences of each group. Pupils work together in small groups, or individually, to create a successful trip. In the first stages of the exercise, the most important skills are working with data such as timetables and percentages. Other areas of mathematics are brought in when the trip begins. The tourists are quite demanding, and it is up to the pupils to keep them happy by solving any problems that may arise, presented algebraically or geometrically. Outbreak Outbreak is centred on an outbreak of a fatal virus. Pupils play the role of a scientist trying to contain the spread of the disease. Pupils have to develop a strategy which will help find the infected people, create an antidote and plan a vaccination programme to minimise the further spread of the virus. Pupils work with different experts to help with the challenges. Completing an activity in any one of the ‘bunker areas’, unlocks a code which can then be used in the Map Room to reflect the progress that individuals or groups have made. This provides the opportunity either for the whole class to work through different activities at the same time, or for independent progression. It also promotes group work discussion and real world interaction. PointZero PointZero is an adventure-driven puzzle game based around the central themes of survival, escape and the quest to uncover the truth. Pupils assume the role of three lead characters who have awoken trapped in strange and varying locations in an unfamiliar urban environment, following an undisclosed event. They are encouraged to use their mathematical skills to overcome problems so that each character can gain access to the ‘PointZero’ Building. Examples of activities include exploring complicated number sequences to scale a high rise building, using loci to find the way out of a complex underground network and reproducing geometrical patterns to deactivate a museum security system. PointZero encourages pupils to reflect on how numbers, algebra and geometry influence our daily lives, albeit in ways which may not be immediately apparent. r4 Â © 2008 Bowland Charitable Trust 7 of 9 Product wars Pupils are asked to create a new range of ‘smoothie’ drinks. They use proportional reasoning to analyse the nutritional value and geometry to design the packaging. In Product wars, pupils play the role of being part of a drinks company and work with other employees to research and design the ultimate range of ‘smoothie’ drinks. The Managing Director of the company, Brad King, asks pupils to carry out market research, develop mixes or some ‘smoothies’ and then design and create the packaging. Video is used at key points in the lessons to provide support and guidance. Activities include: using enquiry-based learning to collect and analyse information from peers in developing the product; using ratio and proportion, percentages and a spr eadsheet to mix the ingredients in different quantities to obtain the right nutritional value and taste for the target sector; and identifying suitable packaging designs. Pupils receive feedback via texts from members of the product team and video messages from Brad King himself. Reducing road accidents Pupils imagine that they live in a small town where, over the past year, there has been a large number of road accidents. The town council has set up an enquiry to see what could be done to improve the situation and has allocated ? 100,000 to spend on reducing the number of deaths and serious injuries. In Reducing road accidents, pupils choose from a wide range of possible initiatives, for example, to build new road crossings or roundabouts, to install traffic lights or to design publicity campaigns for specific groups of people. Pupils work in small teams to plan the most effective way to allocate the money. To support this work, the police have provided data on all the road accidents. Pupils use a specially constructed computer program to analyse this data and build a convincing case for their proposal. Save a baby kangaroo Save a baby kangaroo is an authentic context in which the pupils find a young orphaned kangaroo just twelve centimetres long and weighing sixty grams. Different species of kangaroo have different nutrient needs at different stages of their growth. Through video clips, photographs and data such as birth to adult weights, pupils become familiar with a range of data about the different species of kangaroo. They then use the data to identify which kangaroo they have found and develop a feeding programme to save the life of their own ‘Joey’ in a simulation. Finally they communicate what they have learned in order to help someone else save a Joey by making a poster for a Vet clinic. The mathematical content of Save a baby kangaroo includes creating alternative representations of data and communicating statistical information. Speed cameras Speed cameras are a continuing source of controversy, and even the experts are divided on their effectiveness. This is partly because the random nature of accidents makes it difficult to draw valid conclusions, which opens up possibilities for accidental or deliberate misrepresentation of data. Speed cameras uses video and newspaper resources to motivate discussion with and among pupils; this is combined with the use of spreadsheets to model the random occurrence of accidents over a year. Pupils realise that lower probabilities do not invariably lead to fewer accidents, and that the occurrence of more accidents in one year is not necessarily evidence of a higher probability. They learn that random variation can obscure r4 Â © 2008 Bowland Charitable Trust 8 of 9 underlying probabilities. These are difficult but fundamental concepts for pupils to understand, and the combination of ICT and continual referral to a real situation helps to bring them alive. The emphasis is on pupils interpreting and extrapolating from data and using data to support their arguments – and to examine the arguments of others. Sundials Sundials introduces pupils to the idea of using the sun to tell the time, applying a range of mathematical skills to understand some of the theory and to construct at least one sundial for themselves. A video about sundials provides the context, including footage explaining the history of sundials and how they work. An interview with Harriet James, a gnomonist (someone who makes sundials) shows how maths is essential to the construction of sundials. The classroom work is differentiated into three tiers. Depending on the route followed, Sundials uses symmetry and the drawing of angles, nets, origami, circle work and comparing data. Each route includes reading information from graphs and calculating time. Sundials invites pupils to reach out to the clockwork of the heavens! Water availability Pupils take the role of administrators for an international aid agency charged with providing water resources to countries in the Middle East and North Africa. Pupils examine ways to compare the availability of water fairly between the countries and then determine which country is most in need. In Water availability, pupils review documents that describe the importance of water in the region and assemble relevant data. Pupils come to recognise that a key aspect of data handling is to determine which data it is appropriate to use to answer a particular question. In Water availability, the analysis requires the creation of compound measures, such as per capita measures of water availability, which links to the maths of proportionality. Pupils realise that compound measures are important to enable fair comparisons to be made between countries of various sizes. You reckon? The media (and political speeches) are full of claims about how long things will take, how much things will cost and how tricky problems can be solved. People need to be able to judge if such claims are reasonable. You reckon? develops pupils ability to make estimates about unusual quantities based on only limited information, by posing interesting questions such as Is it possible to provide 20% of the diesel used for road transport in the UK by growing crops on ‘set aside’ land? . You reckon? develops mathematical thinking and requires pupils to communicate their solutions. Pupils see that the problems they are asked to solve are the same problems faced by aid agencies, governments, and salesmen! You reckon? helps pupils to recognise the power of even simple mathematics (together with smart thinking) when making decisions about important topics. r4 Â © 2008 Bowland Charitable Trust 9 of 9

Finances and Accounting

Finances and Accounting The Philosophy of Public Finance Mason Gaffney is one of the philosophers in the economic world who has created the philosophy of public finance. One of the principles of this philosophy is that a person does not pay taxes from the land, this is the land gives money for payment. Therefore, Gaffney draws a line between an owner and a land.Advertising We will write a custom coursework sample on Finances and Accounting specifically for you for only $16.05 $11/page Learn More Then, Gaffney refers to the ways when taxes should be either reduced or eliminated, these are the cases when money are gained for public purposes, when the owner uses the land to serve others and when he/she has to hire labor. The finances presupposed for taxes should be spend on other issues. Gaffney is also sure that people who possess land should pay more in comparison with those who do not possess it as it is obvious that those who have land have more income and can pat taxes in compari son with those who do not have land as additional indirect income. The â€Å"ability-to-pay† idea seems rather attractive to many philosophers of public finances. This point of view is interesting as it preserves incentives. The core idea of this philosophic idea is â€Å"a logical extension of the productivity theory of distribution where people are to be rewarded according to their contribution to the joint products of the economy† (Gaffney, 1998, p. 177). Considering the building on the new houses, the landowners in this case should be reduced from the taxation as new buildings promote the development of the city and land, in this case, is considered as public value. Additionally, the flourishing of a city increases the land taxation and the income for public needs. Governmental Accounting and Nongovernmental Accounting According to Governmental GAAP Guide 2009, governmental accounting deals with public corporations and the bodies which work with politics. Additiona lly, the entities may be considered as the government if they meet the following requirements, the elections to one or more states takes place, â€Å"the potential for unilateral dissolution by a government with net assets reverting to a government† (in Crawford Loyd, 2008, p.1-24) and an entity possess the power to enact a tax levy. Nongovernment accounting deals with the entities which do not possess any of these characteristics. Therefore, it may be said that the main difference between governmental accounting and nongovernmental accounting is the details of payment. If the financial operations are directed at elections and other supportive aspects, the accounting is governmental. If payment is directed at other particular purposes, the accounting is governmental. The Relationship between Budgeting and Financial Reporting in Government Reposting has become one of the most essential aspects of budgeting and governmental accounting. The information resented in reports is ai med at helping control budget expenses and follow the violation if it takes place. In most cases the information is delivered every 45 days after the end of a fiscal year, however, there are situations when reports are to be completed within a month or for special demand. The reports are created by the audits which work in and auditory companies.Advertising Looking for coursework on business economics? Let's see if we can help you!

The Paradox of Wealth and Poverty Research Paper

The Paradox of Wealth and Poverty - Research Paper Example tion is said to have become wealthier according to the generally accepted measures, a significant portion of the population actually become poorer day by day. This gives rise to a paradoxical situation in which wealth and poverty simultaneously increase in an economy. An attempt in recent years to find a solution to this globally prevalent problem has been the made by nations by implementing the concept of â€Å"Microfinance†, which ensures provision of a wide range of financial services to the very poor. One of such most important financial services is the issue of â€Å"microcredit† to the poor, who are usually unable to get financial support from the conventional credit system due to a number of reasons.
