Three-river-source ecological environment protection strategy Essay

Three-river-source ecological environment protection strategy - Essay Example To achieve ecological and environmental protection in this region, an innovative environmental protection strategy is required. New developments in environmental policy, coupled with a new global awareness are sure to help the environmental cause. The establishment of a permanent ecological conservation zone will serve as a model for the region. The establishment of the Three-River source region’s ecological protection foundation is crucial, and so is building a long-term ecological environment compensation policy. The compensation policy serves for relocating people, who depend on the region, to towns and cities, in order to restore its rivers’ ecological environment. The establishment of an ecological conservation zone has become an important protection activity in natural areas around the world. The establishment of an ecological conservation zone is not only beneficial for conserving the flora and fauna, but it also generates economic benefits for communities living in rural and remote areas. Generally speaking, conservation strives to practice the sensible use of natural resources and maintains the biological diversity. It limits the adverse effects of human activities by establishing an ecological conservation zone. It serves to restore timber, improve water quality and provide an area to graze livestock. Conservation practice concerns all kinds of disciplines. It is relevant for subjects- such as philosophy, economics, and sociology - that are concerned with the social environment.

Methods of Data Collection Essay Example for Free

Methods of Data Collection Essay Introduction: Data Collection is an important aspect of any type of research study. Inaccurate data collection can impact the results of a study and ultimately lead to invalid results. Data collection methods for impact evaluation vary along a continuum. At the one end of this continuum are quantitative methods and at the other end of the continuum are qualitative methods for data collection. Bakhtadze (2012:82) ‘When you have decided on a topic, refined it and specified objectives, you start considering the ways of collecting the evidence you require. The initial question that guides you is: â€Å"What do I need to know to answer my research problem? Why do I need it?† After you have answered the question you start choosing the best ways of collecting information. Researchers next decide how they are going to collect their empirical research data. That is they decide what method of data collection (test, questionnaires, focus group, observation, interviews) they are going to use to physically obtain research data from their research participants.’ University of Wilconsin (2012)The Quantitative data collection methods, rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. They produce results that are easy to summarize, compare, and generalize. Quantitative research is concerned with testing hypotheses derived from theory and/or being able to estimate the size of a phenomenon of interest. Depending on the research question, participants may be randomly assigned to different treatments. If this is not feasible, the researcher may collect data on participant and situational characteristics in order to statistically control for their influence on the dependent, or outcome, variable. If the intent is to generalize from the research participants to a larger population, the researcher will employ probability sampling to select participants. Typical quantitative data gathering strategies include: * Experiments/clinical trials.   * Observing and recording well-defined events (e.g., counting the number of patients waiting in emergency at specified times of the day). * Obtaining relevant data from management information systems. * Administering surveys with closed-ended questions (e.g., face-to face and telephone interviews, questionnaires etc). Wikipedia (2012) In statistics, survey methodology is the field that studies the sampling of individuals from a population with a view towards making statistical inferences about the population using the sample. Polls about public opinion, such as political beliefs, are reported in the news media in democracies. Other types of survey are used for scientific purposes. Surveys provide important information for all kinds of research fields, e.g., marketing research, psychology, health professionals and sociology. A survey may focus on different topics such as preferences (e.g., for a presidential candidate), behavior (smoking and drinking behavior), or factual information (e.g., income), depending on its purpose. Since survey research is always based on a sample of the population, the success of the research is dependent on the representativeness of the population of concern. Survey methodology seeks to identify principles about the design, collection, processing, and analysis of surveys in connection to the cost and quality of survey estimates. It focuses on improving quality within cost constraints, or alternatively, reducing costs for a fixed level of quality. Survey methodology is both a scientific field and a profession. Part of the task of a survey methodologist is making a large set of decisions about thousands of individual features of a survey in order to improve it. The most important methodological challenges of a survey methodologist include making decisions on how to: * Identify and select potential sample members. * Contact sampled individuals and collect data from those who are hard to reach (or reluctant to respond). * Evaluate and test questions. * Select the mode for posing questions and collecting responses. * Train and supervise interviewers (if they are involved). * Check data files for accuracy and internal consistency. * Adjust survey estimates to correct for identified errors. Advantages * They are relatively easy to administer. * Can be developed in less time compared with other data-collection methods. * Can be cost-effective. * Few experts are required to develop a survey, which may increase the reliability of the survey data. * If conducted remotely, can reduce or obviate geographical dependence. * Useful in describing the characteristics of a large population assuming the sampling is valid. * Can be administered remotely via the Web, mobile devices, mail, e-mail, telephone, etc. * Efficient at collecting information from a large number of respondents. * Statistical techniques can be applied to the survey data to determine validity, reliability, and statistical significance even when analyzing multiple variables. * Many questions can be asked about a given topic giving considerable flexibility to the analysis. * Support both between and within-subjects study designs. * A wide range of information can be collected (e.g., attitudes, values, beliefs, and behaviour). * Because they are standardized, they are relatively free from several types of errors. Disadvantages The reliability of survey data may depend on the following: * Respondents motivation, honesty, memory, and ability to respond: * Respondents may not be motivated to give accurate answers. * Respondents may be motivated to give answers that present themselves in a favorable light. * Respondents may not be fully aware of their reasons for any given action. * Structured surveys, particularly those with closed ended questions, may have low validity when researching affective variables. * Self-selection bias: Although the individuals chosen to participate in surveys are often randomly sampled, errors due to non-response may exist ( Adà ©r et al. (2008:13) . That is, people who choose to respond on the survey may be different from those who do not respond, thus biasing the estimates. For example, polls or surveys that are conducted by calling a random sample of publicly available telephone numbers will not include the responses of people with unlisted telephone numbers, mobile (cell) phone numbers, people who are unable to answer the phone (e.g., because they normally sleep during the time of day the survey is conducted, because they are at work, etc.), people who do not answer calls from unknown or unfamiliar telephone numbers. Likewise, such a survey will include a disproportionate number of respondents who have traditional, land-line telephone service with listed phone numbers, and people who stay home much of the day and are much more likely to be available to participate in the survey (e.g., people who are unemployed, disabled, elderly, etc.). * Question design. Survey question answer-choices could lead to vague data sets because at times they are relative only to a personal abstract notion concerning strength of choice. For instance the choice moderately agree may mean different things to different subjects, and to anyone interpreting the data for correlation. Even yes or no answers are problematic because subjects may for instance put no if the choice only once is not available. Questionnaires Wikipedia (2012)A questionnaire is a research instrument consisting of a series of questions and other prompts for the purpose of gathering information from respondents. Although they are often designed for statistical analysis of the responses, this is not always the case. The questionnaire was invented by Sir Francis Galton. Questionnaires have advantages over some other types of surveys in that they are cheap, do not require as much effort from the questioner as verbal or telephone surveys, and often have standardized answers that make it simple to compile data. However, such standardized answers may frustrate users. Questionnaires are also sharply limited by the fact that respondents must be able to read the questions and respond to them. Thus, for some demographic groups conducting a survey by questionnaire may not be practical. As a type of survey, questionnaires also have many of the same problems relating to question construction and wording that exist in other types of opini on polls. Basic rules for questionnaire item construction * Use statements which are interpreted in the same way by members of different subpopulations of the population of interest. * Use statements where persons that have different opinions or traits will give different answers. * Think of having an open answer category after a list of possible answers. * Use only one aspect of the construct you are interested in per item. * Use positive statements and avoid negatives or double negatives. * Do not make assumptions about the respondent. * Use clear and comprehensible wording, easily understandable for all educational levels * Use correct spelling, grammar and punctuation. * Avoid items that contain more than one question per item (e.g. Do you like strawberries and potatoes?). Questionnaire administration modes Main modes of questionnaire administration are: * Face-to-face questionnaire administration, where an interviewer presents the items orally. * Paper-and-pencil questionnaire administration, where the items are presented on paper. * Computerized questionnaire administration, where the items are presented on the computer. * Adaptive computerized questionnaire administration, where a selection of items is presented on the computer, and based on the answers on those items, the computer selects following items optimized for the ‘testees ‘estimated ability or trait. -Wikipedia. Org Observational study In epidemiology and statistics, an observational study draws inferences about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator. This is in contrast with experiments, such as randomized controlled trials, where each subject is randomly assigned to a treated group or a control group before the start of the treatment. Wikipedia (2012)Although, observational studies cannot be used as reliable sources to make statements of fact about the safety, efficacy, or effectiveness of a practice, they can still be of use for some other things: [T]hey can: 1) provide information on â€Å"real world† use and practice; 2) detect signals about the benefits and risks of[the] use [of practices] in the general population; 3) help formulate hypotheses to be tested in subsequent experiments; 4) provide part of the community-level data needed to design more informative pragmatic clinical trials; and 5) inform clinical practice.’ Bakhtadze (107:2012) Observation is watching behavioral patterns of people in certain situations to obtain information about the phenomenon of interest. Quantitative Observation: Quantitative Observation involves the standardization of all observational procedures in order to obtain reliable research data. Qualitative Observation: Qualitative Observation involves observing all relevant phenomena and taking extensive field notes without specifying in advance exactly what is observed. Focus Groups Bakhtadze (106:2012) A focus group is a type of group interview in which a group moderator (working for the researcher) leads a discussion with a small group of individuals to examine how the group members think and feel about the topic. Purposes of Focus groups: 1. Obtaining general background information about a topic of interest; 2. Stimulating new ideas and creating concepts; 3. Generating impressions of products, programs, services, etc. 4. Learning how respondents talk about the phenomenon of interest; 5. Interpreting previously obtained qualitative results Summary A method of data collection is the procedure that a researcher uses to physically obtain research data from research participants. The method of data collection that is used in a research study is discussed in the method section of a research report. . Finally, the methods of data collection discussed in this paper work can be mixed by using the fundamental principle of mixed research to strengthen the evidence provided by a research study.

Ajuga Orientalis L Anatomy Studies

Ajuga Orientalis L Anatomy Studies The anatomical studies of medicinal taxon Ajuga orientalis L. (Lamiaceae) from Turkey Abstract. Ajuga orientalis[a1], with a wide distribution area in Turkey, is traditionally used medicine in the treatment of some skin diseases in Anatolia. The aim of this study is to determine the anatomical characteristics of the root[a2], leaf, petiole, calyx and corolla of medicinal taxon [a3]A. orientalis in cross sections. As a result of the study, it was found that the pith rays of root are composed 3-4 rowed cells and stem was quadrangular[a4]. There were glandular and non-glandular hairs on the surface layers on stem, leaves, petiole, calyx and corolla. Starch particles were also identified[a5] in the cortex cells of stem. The stomata were diastic[a6] and the leaf was bifacial. There were one big vascular bundle in the center and 4-5 small vascular bundles on each corner of the petiole. It was also determined that adaxial epidermis cell shapes of corolla are papillose type. Key words: Ajuga orientalis, anatomy, medicinal plant, Turkey INTRODUCTION The Lamiaceae is a large family showing natural distribution. Most of species belonging to this family are shrubby and herbaceus, and trees are extremely rare (Heywood, 1978). The family with its more than 250 genera and approximately 7000 species, has a cosmopolitan distribution (Thorne, 1992). According to BaÃ…Å ¸er (1993), Turkey is accepted as a gene center for this family. Many species of this family are aromatic and are often used as herb spices, folk medicines and fragrances (Werker et al., 1985). With their pleasant fragrance, many species of Lamiaceae have been used as herbal teas in Turkey. Many of species are used as raw material in the cosmetic industry. Some species are traditionally used as medicinal plants (Baytop, 1984). It was reported that some Ajuga L. and Salvia L. species are cultivated as ornamental plants (Baytop, 1984; Ãâ€"zdemir and Ã…Å ¾enel, 2001; Akà §in et al., 2006). In addition to this, Lamiaceae has great importance due to its economical valu e and its variety of species. The genus Ajuga L. belongs to Lamiaceae family. Ajuga L. is represented in Turkey by 13 species and 22 taxa, six species and one subspecies being endemic (Davis et al., 1982-1988). Ajuga species are used in folk medicine in different parts of the world for the treatment of rheumatism, gout, asthma, diabetes, malaria, ulcers and diarrhea and have antibacterial, antitumor, antifeedant, and vulnerary properties (Chen et al., 1996; Ben Jannet et al., 2000). Baytop (1999) reported that some Ajuga species generally known as â€Å"mayasÄ ±l otu† in Turkey have been widely used for their aromatic, diuretic, antipyretic, tonic, diaphoretic, astringent, bitter and homeopathic properties in the Turkish folk medicine. Ajuga orientalis L. one of the species of Ajuga genus is used against some skin diseases by hug on the skin in Anatolia (Koyuncu et al., 2010). Although many species of Lamiaceae family are investigated anatomically (ÇobanoÄÅ ¸lu, 1988; Uysal et al., 1991; Ãâ€"zdemir and Altan, 2005; AktaÃ…Å ¸ et al., 2009) there is no anatomical study of A. orientalis L. in literature. Due to its medicinal importance mentioned above in this study, the purpose of this study is to determine the anatomical characteristics of A. orientalis L. MATERIALS AND MEDHODS In the present study, the plant specimens of A. orientalis were collected during the flowering period and natural populations in A5 Amasya (in the vicinity of Direkli village, open areas, at 1800 m, June 2012, Ä °Ãƒâ€"ztà ¼rk ÇalÄ ± 461) which is a city in the Black Sea region of Turkey. Its taxonomical description was carried out according to Davis (1982). Anatomical investigations were performed using an average of fresh specimens kept in 70% alcohol. Cross sections of root, stem, laeve, petiole, calyx and corolla were taken from 30 specimens of A. orientalis and 50 measurements were conducted for each parameter. Transverse sections were made by hand using commercial razor blades and stained with Sartur reactive (ÇelebioÄÅ ¸lu and Baytop, 1949). Measurements in the sections were performed under a Leica ICC50 HD binocular light microscope by using a Leica Digital Camera and objectives used were x10 and x40. Photographs were taken with a Leica ICC50 HD binocular light microscope and a Leica Digital Camera. RESULTS In cross-sections taken from the root, stem, leaf, petiole, calyx and corolla of A. orientalis , the following significant properties were observed below. In the transverse section of the root, there was a periderm which was the outermost layer of the root of A. orientalis (Figure 1). The periderm had 8-9 layers. The dimensions of periderm cells were 15 – 60 X 15 – 57.5  µm (Table 1). Beneath the periderm, there was the multi-layered cortex, composed of ovaidal and parancyhmatic cells. The cortex was 9-10 layers. The cambium, composed of 3-4 layered, was located between the xylem and the phloem. Beneath the cambium, there were xylem tissue (7.5 – 15 X 7.5 – 20  µm) composed of regular trachea and tracheid cells. Xylem cells were also present in the center, so the pith is not seen in the center. There were 3-4 layered primary pith rays between the secondary xylem cells. A. orientalis, as a typical characteristic of the Lamiaceae, had a 4-angle stem. Its epidermis usually had one layer composed of ovoidal cells (12.5 – 42.5 X 17.5 – 50  µm). The upper surface was covered with a cuticle (1.25 – 2.5  µm). There were glandular and non-glandular hairs on the epidermis (Figure 2). Transverse section of the stem revealed 9-10 layered collenchyma placed on the corners. The cortex was composed of 6-7 layered paranchymatous cell. The dimensions of paranchymatous cells were 27.5 – 75 X 15 – 55  µm (Table 1). Starch particles were also observed in the paranchymatous cells of stem (Figure 3). There were 2-3 layers of sclerenchyma in the outer side of phloem. Right beneath the phloem, there was a 1-2 rowed cambium layer. The xylem tissue existing beneath the cambium was composed of regular trachea and tracheid cells. The vascular bundles were bigger on the corner than other parts of stem. Between the corners there were als o numerous small bundles in the A. orientalis stem. The vascular bundles were collateral (Figure 2). The pith was wide and consist of flat cells with intercellular spaces. There was a cavity in the centre of the pith. In the leaves, the epidermis was single layered on upper and lower surface. There were glandular and non-glandular hairs on epidermis. The cuticle was 2.5 – 5  µm thick. Just beneath the upper epidermis cells, there were 2-3 rowed palisade parenchyma cells (Figure 5). The dimensions of the palisade parenchyma cells were 12.5 – 25 X 25 – 50  µm (Table 1). The 2-3 rowed spongy parenchyma existed beneath the palisade. The spongy parenchyma covered less space than does the palisade parenchyma. The collateral vascular bundle was located in the midrib region (Figure 5). There were sclerenchyma cells in the outer side of phloem. All vascular bundles in the leaves were surrounded by bundle sheet cells. The stoma was diastic and the leaf was bifacial (Figure 4 and Figure 5). The stoma presented on upper and lower surfaces of the leaf (Figure 4). Both adaxial and abaxial epidermis cells were single layered in the petiole (Figure 6). The dimensions of the adaxial epidermis cell were 15 – 45 X 17.5 – 27.5  µm while those of the abaxial epidermis one were12.5 – 27.5 X 15 – 17.5  µm (Table 1). There were a lot of glandular and non-glandular hairs on epidermal cells which were ovoidal-rectangular shapes. Parenchymatic cortex cells were 10-11 layered. There was one big vascular bundle in the center and 4-5 small vascular bundles at each corners of petiole. The vascular bundles were surrounded by sclerenchymatic cells (Figure 6). There were parenchmatic bundle sheets on the all vascular bundles. The type of vascular bundle was collateral (Figure 6). There were 2-3 layered collenchyma in the area between the corners. In the calyx, the adaxial epidermis cells were smaller than abaxial epidermis cells. The dimensions of adaxial cuticle were 1.25 – 2.5  µm whereas the those of the abaxial cuticle is 2.5 – 3.75  µm (Table 1). Parenchymatic cells were flat ovoidal. There were glandular and non-glandular hairs on the epidermis (Figure 7a). In the cross-section of corolla, cuticle was present on both abaxial and adaxial epidermis cells covered by glandular and non-glandular hairs. The shapes of adaxial epidermis cells were papillose type (Figure 8). Beneath the adaxial epidermis, there were the parenchyma cells with intercellular spaces (Figure 7b). There was a vascular bundle in the midrib. DISCUSSION The present study provided useful information on the anatomy of A. orientalis. Few studies on the species A. orientalis had been found in literature (Sajjadi and Ghannadi, 2004; Koyuncu et al., 2010). But, the measurements and observation of anatomical characters belonging to the medicinal taxon A. orientalis were reported for the first time in the present paper. Metcalfe and Chalk (1972) determined some imported anatomical information about root anatomy of Lamiaceae family. They stated that the pith rays of roots of the family are 2-12 or more rowed cells. It was found that the pith rays of A. orientalis were composed 3-4 rowed cells. These findings were consistent with those of Metcalfe and Chalk (1972) and those of some studied species of Lamiaceae (Baran and Ãâ€"zdemir, 2006; Ãâ€"zkan and Soy, 2007; Baran and Ãâ€"zdemir, 2009). Metcalfe and Chalk (1972) also stated that the members of Lamiaceae family have quadrangular with well-defined collenchyma in the four angles and scleranchymatous tissue surrounds the phloem groups of vascular bundles. In the transverse section of A. orientalis, the stem of this species was quadrangular with well-defined collenchyma in the four angles. It was also determined that there were 2-3 layers of sclerenchyma in the outer side of phloem in this study. Quadrangular stem with well-defined collenchyma in th e four angles and scleranchymatous tissue surrounds the phloem groups of vascular bundles were observed in other members of Lamiaceae family (Metcalfe and Chalk, 1972; Kandemir, 2003; Baran and Ãâ€"zdemir, 2006; Kahraman et al., 2010). The vascular cambium located between the phloem and the xylem was 1-2 rowed layer in the stem of A. orientalis. The vascular cambium was seen in the cross-sections of other members of Lamiaceae family (Dinà § and Ãâ€"ztà ¼rk, 2008; Baran and Ãâ€"zdemir, 2009). There were big vascular bundles on the corners of A. orientalis stem whereas a lot of small bundles between the corners were observed in the present study. There were also starch particles in the paranchymatous cortex cells of stem. The leaf of A. orientalis had 2-3 layered palisade parenchyma and 2-3 layered spongy parenchyma cells. Baran and Ãâ€"zdemir (2009) also stated that Lamium lycium which is the member of Lamiaceae family has 2-3 layered palisade parenchyma and 2-3 layered spongy parenchyma cells as well. These results were parallel to our results mentioned above. On the other hand, the stoma type of A. orientalis was diasitic and the leaf was bifacial. According to Metcalfe and Chalk (1972), diasitic stoma type was most common in Lamiaceae family. Diasitic stoma and bifacial mesophyll type were also observed on the leaf of Ajuga chamaepitys and Ajuga reptans (Akà §in et al., 2006). The stomata were observed on both upper and lower surfaces of the leaf. Metcalfe and Chalk (1972) stated that the structure of the vascular bundles in the petiole of the species in the Lamiaceae could be used as a diagnostic character. The structure of petiole shows differences between genera and species. In addition to this, useful petiole anatomical characters are determined in designated taxonomical structures of some species (Shaheen, 2007; Eric et al., 2007). In the petiole of A. orientalis, there was one big vascular bundle in the center and 4-5 small vascular bundles at e ach corner of the petiole. Akà §in et al. (2011) found that Ajuga reptans has a total of nine vascular bundles: one big bundle in the middle and 4 vascular bundles at each corner. The vascular bundles of leaf were surrounded by sclerenchymatic cells. Collenchyma in the petiole is 2-3 layered at the each corners. In the cross-section of calyx and corolla, both adaxial and abaxial epidermis cells were covered with cuticle. In addition to this, there were a vascular bundle in the midrib of calyx and corolla. The adaxial epidermis cells of corolla were papillose type. The most distinguishing characteristics of the species in the anatomical structure were the presence of glandular hairs on the surface layers on stem, leaves, petiole, calyx and corolla. Like other other members of the Lamiaceae, A. orientalis had both glandular as well as non-glandular trichomes. Glandular trichomes were mainly observed on calyx and corolla, but non-glandular ones were found on the stem, leaf surface and petiole. According to Metcalfe and Chalk (1972), having glandular and non-glandular trichomes are important anatomical characters. Glandular trichomes significant taxonomic character and act imported role for pollination in the Lamiaceae family (Navarro and El Oualidi, 2000). As a result, anatomical characters of medicinal taxon A. orientalis were studied for the first time in this paper. According to the results mentioned above, the anatomical features of root, stem, leaf, petiole, calyx and corolla provided useful characteristics for distinguishing species in Ajug a genus.

Great Expectations and Family Relations :: Charles Dickens Great Expectations Essays

Charles Dickens remains one of the most prominent and certainly the most commercially successful literary artist of nineteenth century England. In addition, Dickens enjoyed a large readership in America. The author’s success on both sides of the Atlantic Ocean stems from his entertaining literary style and his deep respect for social values and the human condition he encountered and incorporated into his writing. Dickens was a prolific writer who drew upon his personal experiences and integrated a certain comic pathos in his writing to delight his reading audience. Dickens can be aptly termed a chronicler of English life as his novels and stories accurately reflect various societal ills and joys of both urban and suburban England. Indeed, his novels and stories continue to amuse and sadden readers of all ages today. This unit will attempt to introduce Charles Dickens and his work to middle school students. The primary focus of this unit is to examine Great Expectations as a novel rich in familial relationships. The novel will be read and studied as a myriad of interacting families, and hopefully these insights will be suitably translated to my students in such a manner as to heighten their awareness of familial relationships they encounter on a daily basis. Great Expectations will allow my students to experience glimpses of nineteenth century English family life as Dickens most capably perceived it. The questions and concerns evoked by the novel will also cause the students to reflect upon family concerns of twentieth century America. Although Dickens was one of eight children and fathered ten himself making him somewhat of a viable source concerning family relationships, the reader is cautioned not to expect only a discussion of the nuclear family from this unit but also a wide array of f amily-like relationships which are characteristic in Dickens’ writing. Great Expectations is a novel of hope and heartbreak, identity and intrigue. The story focuses upon a central character, Pip, who relates his adventures to the reader through Dickens’ stylistic use of the first person point of view. Pip is raised by his sister and her husband, Joe Gargery. Pip’s parents had already died and were buried in the graveyard by the marshes when we first meet him at the age of seven. The reader learns much from Dickens in the opening scenes of the story by his treatment of the family relationship which had been of primary importance to his central character.

An Explanation of the Causes and Effects of the Enron Accounting Scandals

From the 1980s until now, there have been a lot of accounting scandals which were widely announced on by media. The result of this situation is many companies were bankruptcy protection requests, and closing. One of the most widely reported emulation of accounting scandals is Enron Company. Enron Corporation is one of the largest energy companies in the world. Enron was founded in Houston, Texas, America in July 1985 by the consolidation between Houston Natural Gas and InterNorth of Omaha, Nebraska (â€Å"Enron and Enderson: The story†, n. d. ). According to Sridhanran, Dickes & Caines (2002, p. ), Enron’s rank number is the seventh in the United States by Fortune magazine in April 2002.Their businesses were sale of nature gas, electricity sector, water, metal, broadband and newsprint. Enron has been altered from the old economy company to the new economy company and focus on HFV (Hypothetical Future value). The profits were grown by buying electric at stable prices fro m the suppliers and sale the different prices for customers. When the falsehood of their profits was opened, the investors withdraw the capital. Enron start collapse (â€Å"Case study: The collapse†, n. . , pp. 1-2). Definitions Accounting scandals are political and business scandals using illegal accounting systems and fraud in the financial statements. According to Hanson (2002, p. 1), Enron accounting scandal is the most important common failure in the banks during the 1980s in the United States. This leads to changing in business and the law. When Enron was bankrupt, the economy of America was dropped, and many employees were lost their jobs. Outline and Limitations The assignment will explain two main reasons and two effects of Enron accounting scandal.The assignment will conclude with review the Enron accounting scandal and giving the lessons for another company. The Causes of Enron Accounting Scandal Business Fraud A business fraud is one of the most important reasons which made bankruptcy of Enron. Firstly, limited partnership companies were opened by CFO Andy Fastow. He used many partnership companies such as J. P. Mogan Chase and Merill Lynch to hide their enormous debts and losses from investors. They borrowed the great amounts of money from financial institutions to buy many assets; this led to wrong view about Enron condition.It helped the stock price increase (â€Å"Enron accounting scandal†, 2009). In addition, the financial strategy, the business consultants and the accounting techniques are wrong choice of Enron. They used established investment money to build securitization abilities. According to Buondonno, David, Pufky and Rollings (n. d. , pp. 11-12), Enron has distorted the financial statements using the complex methods. They used fake companies (SPEs) to move money between different banks and created false financial statements. This led to misunderstanding of shareholders about the real financial statements.Moreover, Enron predicted the future market of energy price. As a result, the sale prices of Enron known as mark-to-market, which control the energy trading business and the reports which they want to show. Furthermore, Enron used wrong accounting system. They used mark-to-marked trading which is greatly hard to change to another system. The reports were shown losses or gains on the stock and security price at the end of the year. Enron was able to use SPE (special purpose entities) to trade in legal time or illegal time so that income could change to correct with investor expectances.Lastly, Enron had a huge negative dollar cash flow from bank loans. They needed to pay around two million dollars per day by cash. A Corruption and a Lack of Accounting Techniques According to Buondonno, David, Pufky and Rollings (n. d. , pp. 18-20), Management level and accounting level were forgotten in Enron situation. Endrew Fastow, the Chief Financial Officer (CFO) of Enron used his power to corrupt by using his knowledge into the agreements and making the bonuses from the agreements. Endrew and his wife got benefits from Enron to buy Chewco where his wife is owner.He controlled subsidiary companies to buy stock and hid debt for Enron. Enron did not follow the accounting rules. Every mistake in accounting needs to note and describes for shareholders know, and writes on the financial statements. In 2001, Accountants cannot combine Chewco into the Enron’s financial statement. This lead to misunderstanding report which show the financial statement of Enron such as a decrease Enron income and an increase Enron’s reported debt. In addition, Enron tried to make maximize profits by break the law.Therefore, dishonesty in the financial statement, corruption and a lack of knowledge and skills of accountants are the causes of the Enron’s bankruptcy. The Effects of Enron Accounting Scandal on Employees and shareholders When Enron was bankrupt, the most affected people are Enronâ₠¬â„¢s workers and shareholders. Many people lost their jobs, their whole pension and all of the shareholders lost their money (Dunder,n. d. ). According to Raver (2006, p4-5), Enron stocks prices were increased nearly double in one year by many ways such as legal and illegal way.The stock price was increasing so fast, many Enron employees bought Enron stock as saving money, and also their pension are in Enron’s stock too. When Enron was failing, Enron’s stock price was decreasing until no longer value, many Enron workers lost all their money, their jobs and also their pension lost too. For this reason, they almost have nothing; they only have social security funds. The suddenly decrease of the value in Enron stocks influenced the retreat savings of thousands Americans who are not Enron employees. Many Americans saved their money in the index funds.Enron’s stock was formed by the different sources of investment, such as the state pension plans, university and oth er non-profit foundations (Sridharan, Dickes & Caines, 2002, p. 4). Therefore, when Enron scandal was happened, this entailed many effects on workers, shareholders and Americans who are not Enron employees. They lost their money, their jobs and their future. The United States and the Stock Market Enron accounting scandal helped American improve their knowledge of business and accounting. This leads to changing in the U. S. aw to protect people from the business fraud (Raver, n. d. , p. 4). They fortified retirement security of American, and limited on selling stocks for employees (Sridharan, Dickes & Caines, 2002, p. 8). Moreover, the stock market was affects by the Enron accounting scandal, Enron’s stock was $80 per share. When the Enron accounting scandal was discovered, the price of Enron’s stock fell down less than $1 (â€Å"Enron stock prices†, n. d. ). Conclusion The Enron accounting scandal is one of the biggest problems of cheating in accounting in Ameri ca.It changed the most American life, and people behold themselves to know the answers of cupidity and break the law in business. The Enron accounting scandal has many reasons such as business cheating, the corrupt of the power person and inexperience of accountants. For this reasons, Enron bankruptcy had many effects on Americans social such as workers, shareholders, the American economy and the law. The lesson from Enron accounting scandal were found by many ways such as the conflict of interest between two roles played, employees’ protection, changing in business managements, and ethics in business, cautious investment.

Zoom Car Company committed an unintentional tort by selling a car with faulty dashboard compass to Daniel Boone.Advertising We will write a custom essay sample on Legal Issues of Zoom Car Company specifically for you for only $16.05 $11/page Learn More Under torts law, Zoom Car Company should assume liability for any accident that occurs as a result of faults in its cars. Even though Corrigan Rulers Compasses and Slide Rules, Inc. also committed a tort by selling a faulty dashboard compass to Zoom Car Company, it is the responsibility of Zoom Car Company to ensure that all dashboard compasses are in good condition before installing then in their cars. It is clear from the facts provided in the hypothetical case that Daniel Boone, the plaintiff suffered physical injury. It is also clear from the facts in the case that the plaintiff got lost while driving at night and drove into a high crime area mainly due to the faulty dashboard compass installed in his car. The main reason why the plaintiff opted to buy a car from Zoom Car Company was the fact that its cars had dashboard compasses and would thus assist him in finding his direction whenever he is lost. Daniel Boone’s loss was largely caused by the fact that his dashboard compass was faulty. It is as a result of this that Daniel Boone found himself in a high crime area and ended up with physical injury. Had his dashboard compass been in good working condition, Daniel Boone would not have faced such a misfortune and would have also not incurred any medical cost. Under torts law, the defendant is liable for the plai ntiff’s misfortune as it would have been avoided if his car was installed with proper dashboard compass. The defendant unintentionally caused loss to the plaintiff and should thus take responsibility for his medical costs. While it is clear that the plaintiff suffered injury and incurred medical expenses, it is not clear whether the dashboard compass installed in his car was faulty at the time he bought this car from Zoom Car Company. There is a possibility that the plaintiff would have tempered with the dashboard compass. Besides, customers are always given the opportunity to confirm that goods are in good working condition before purchasing them. How come the plaintiff did not detect the faultiness of dashboard compass at the time he was purchasing this car? Is the defendant’s conduct outrageous to have caused the plaintiff his misfortune?

Get your first paper with 15% OFF Learn More The company responsible for manufacturing dashboard compasses is Corrigan Rulers Compasses and Slide Rules, Inc. If the dashboard compasses was not properly installed then, the defendant would be liable. The plaintiff should be clear on whether the dashboard compass was faulty or not properly installed before placing any liability on the defendant. Under civil law, defendant is not directly linked to the plaintiff’s misfortune and, therefore, is not liable to his medical costs. If I was the charge presiding over this case, my ruling would be based on a critical analysis of the facts presented above. First, it is clear from these facts that both the plaintiff and the defendant contributed to the loss suffered by the plaintiff. Under comparative negligence rule, the defendant is only liable for the loss suffered by the plaintiff if he/she had the highest percentage of contribution to the loss. In this ca se, the defendant contributed to the plaintiff’s loss by selling a car with faulty dashboard compass to the plaintiff. The plaintiff contributed to the loss through his negligence as he did not bother to confirm whether the compass was faulty during the purchase of the vehicle and by driving at night when he is not sure of his direction. Apart from comparative negligence, vicarious liability ruling is also applicable in this case. Under vicarious liability, the defendant is liable for harm caused to the plaintiff as a result of a legally binding relationship between them. While this ruling is most applicable when dealing with employee-employer relationship, in this case the car will assume the position of the employee and Zoom Car Company, the employer. It is due to the fault in the car that the plaintiff suffered damage. Since the car was bought from Zoom Car Company, the company should assume any liability arising from faults in the car. Besides, the plaintiff entrusted his future safety to the defendant when he bought a car with dashboard compass assuming that he will never lose his direction. The defendant is thus liable to his loss under torts law as its car failed to fulfill this responsibility. From this analysis, I can conclusively rule that the defendant is liable for loss suffered by the plaintiff. First, the defendant greatly contributed to loss through its negligence. The company ought to verify its devices before installing them to ensure that they are in good working condition. If this was done the damage suffered by the plaintiff would have been avoided. Second, as the company responsible for installing dashboard compasses in their cars, the plaintiff should assume any vicarious liability resulting from faultiness of this device. Zoom Car Company should thus assume liability for Daniel Boone’s medical costs.Advertising We will write a custom essay sample on Legal Issues of Zoom Car Company specifically for you for only $1 6.05 $11/page Learn More
