#3 - Case Study Example Age: with the advancement of age, the condition of presbycussis may become more profound having started from early adulthood sometimes from as young as 18 years. It may occur due to prolonged exposure to noise. Noise inducement: in case one gets exposed at a time to very high frequency sounds, then one can become either partially or permanently deaf. It may be due to destruction of sensorineural nerves. The higher the pitch of the sound exposed to may vary the extent of damage to the ear. Very high noise causes a higher degree of damage in much shorter time than low levels of noise. Genetics: sometimes deafness conditions can be hereditary. Where dominant genes exist between parents, the higher are the chances of the offspring acquiring deafness. Modern science identifies non syndrome and recessive types of deafness. Boys Town Hospital is an institute in Nebraska researching genetic and hereditary deafness. Their website reveals genetic fact sheets and information regarding syndromes related to deafness. Moreover, they offer recruitment to people willing to learn about hearing impairment. It is duly registered by the Registry for Research on Hereditary Hearing Impairment. Lastly, New York Rockefeller has also conducted studies investigating non-syndrome impairment. Other Universities and Medical research institutes across the globe have taken steps to ease the diagnosis and possible remedies on the condition. Ferdinand Berthier was an intellectual and an educator in the late 19th century in France. He was born deaf. He was also a political organiser in France politics. He was the founder of the first organisation that took good care of deaf people. He fought for recognition of deaf people in such capacities as political seats, leadership roles in organisations, stating that disability is not inability. The aim of the organization was, â€Å"to bring together all the deaf

History - French Revolution Essay Example for Free

History French Revolution Essay I truly believe it was the collective effect of all the causes of the French Revolution that finally caused the people to rise up. In 1789 the people of France were suffering under the rule of Louis XVI, who used the countries money to provide him and his family the most luxurious life imaginable, while the people starved. The political regime of the time was a absolute monarchy (regime in which the country is ruled by a King or Queen, who inherit this position and has absolute power), but in theory there was a form of parliament, Estates General that consisted of elected representatives. This group of people could only meet if the King allowed or requested the meeting and in the 175 years of the parliament’s existence there had not been a single meeting. This fact frustrated the people because the King did not take their opinion and needs in consideration. Louis XVI would do as he pleased, a clear example of that was placing people in jail for no absolute reason except maybe his dislike for them. During the 18th century France was in a number of wars leaving the country with a lot of debts. In 1780’s the country had to borrow more money simply to pay interest (the amount of money paid on the money borrowed) on their debts. The royal family had a lifestyle the country could not support because only the lower classes were taxed, the peasants (people who worked on the land), while the higher classes, clergy (the religious leaders, individuals that worked for the roman catholic church, ex: priests) and the nobles (entities with a high social rank, ex: Ladies and Lords) did not pay tax at all. In other words the tax system needed a urgent reform (improvement). The social structure was horribly unfair. It was divided in three groups that were called â€Å"Estates†. The first estate was the Clergy, the people who belong to this estate worked for the Roman Catholic Church, which was at the time the main religion in France. At this specific stage in time the church owned a lot of land and most of their high officials were extremely wealthy. The Nobles formed the second estate. They were given many special rights and privileges. The third estate was made up of 98% of the people. This estate was where all the peasants, middle class traders and all kinds of professionals (ex. Lawyers). They paid heavy tax and had absolutely no privileges at all. Above all the estates was the King and his family with the absolute power. â€Å"It was the collective effect of all the causes of the French Revolution that finally caused the people to rise up. † History Essay Lara Ismael Nogueira Martha  For many centuries people in the whole of Europe accepted the authority of both their Kings and the Roman Catholic Church, a clear example of that was the â€Å"Divine Right of Kings† (this concept simply means that people believed their Kings and Queens were a representation of God and had to be respected and adored as such). Finally during the 18th century many philosophers started questioning these ideas. These period was called the Age of Enlightenment because the people began to question the old ways, led by the church, and created their own. Science had great advances during these times because everything was new, there was something to be discovered everyday†¦ it was at this point that Theocentrism (God in the center of the universe) was put aside and gave room for a complete new way of thinking and living, Anthropocentrism (man in the center of the universe). Diderot was a clear example of a philosopher that question the church and made his opinion well known. He was the leader of a group made up of philosophers that called themselves the â€Å"Encyclopaedists†, they’re goal was to write a series of books called â€Å"Encyclopaedia† (books that contained all existing knowledge). As they began to write the books they became more and more aware of the situation in France. They made their books public, therefore everyone could read them, this act helped spread the revolutionary ideas more than they already were. As the popularity of the Encyclopaedia grew so did the need for individual opinions. Another great example was Rousseau he was the true star, known as the father of democracy, he believed in equality among the people, and wrote about rules that weren’t based or chosen by God but by the people. This was the basic principles of democracy. In May of 1789 the representatives formed the National Assembly and met outside Paris against the Kings will and started a process of reform. They vowed to continue working until they had drawn up a new constitution for the country. However the process was very slow and the people of Paris grew impatient, the bread prices were constantly rising and the unemployment rate grew. On the 14th of July of 1789 angry people invaded the Bastille, killed the governor also some of the soldiers who tried to stop them and freed prisoners. When the news of the takeover reached other parts of France the ordinary people revolted and just like that the revolution started. â€Å"It was the collective effect of all the causes of the French Revolution that finally caused the people to rise up. † History Essay Lara Ismael Nogueira Martha In conclusion all this events such as the rise of bread prices and the unemployment rate in the country, the lack of interest the King showed for his people’s needs and the unfairness between classes made the people of France stand up for all they believed they deserved and needed.

Research Design Location And Research Time Psychology Essay

Research Design Location And Research Time Psychology Essay This chapter will present the methodological approach and research technique used in this thesis along with how the data will be gathered to find the answer or solutions of the research questions and problems, such as research design, theoretical perspective, data collection method, data analysis method as well as the validity and reliability of the data. Research Design, Location, and Research Time This research was planned and designed to obtain answer to research questions. Research design is the framework or plan for study, used as a single guide to collect and analyze the data. It is the blueprint that is followed to complete a study. According to Sekaran and Bougie (2009, p. 24), a research method or approach/design gives details on the most suitable methods of investigating the nature of the research, instruments, the sampling plan and the type of data to be used. Furthermore, Sekaran and Bougie (2009, p. 24) also report that a research method or design forms the framework of the entire research process. Therefore, if it is a good method or design, it will thus ensure that the information obtained is important to the researchers problem and those objectives and economic procedures in collecting it are all within limits. It simply is a systematic quest for undiscovered truth. In pursuit of this undiscovered truth, a researcher needs facts, published documents from primary sources and secondary sources. This research was using a cross sectional study which the data are gathered just once (Sekaran Bougie, 2009, p. 119). Research location was done at six locations: Central Jakarta, North Jakarta, South Jakarta, West Jakarta, East Jakarta and Tangerang city to household customers of PT. Perusahaan Listrik Negara between March to July 2012, with the distribution of questionnaires within June 2012. Research Framework The research framework of this thesis is shown in Figure 3.1 below. The first research step is to define the research problem, followed by research objective. The third step is a literature review, followed by data collection, data analysis, hypothesis test, and finally generate conclusion and recommendation. Source: Author Figure 3.: Research Framework Research Questions and Hypotheses In this study, researcher would like to answer the questions and analyze the hypotheses below: RQ1: How do cultural factors, social factors, personal factors, psychological factors, and PLN services influence customer decision in using electricity at peak load hours? H1: From those factors, all factors are positively influence customer decision in using electricity at peak load hours. RQ2: How is the correlation between the decisions in using electricity during peak load hours with the household customers behavior towards saving electricity? H2: There is a correlation between the decisions in using electricity during peak load hours with the household customers behavior towards saving electricity. RQ3: How do pro-social intensions, motivations, access to information, and knowledge influence customer behavior in saving electricity? H3: From those factors, all factors are significantly influence customer behavior in saving electricity. RQ4: How is the correlation between customer awareness of consequences, aspiration of responsibility, personal norms towards their pro-social intensions in saving electricity? H4: There is STRONG correlation between customer awareness of consequences, aspiration of responsibility, personal norms towards their pro-social intensions in saving electricity? RQ5: What interventions or instruments are most likely to affect households saving electricity behavior? H5: The intervention or instrument most likely to affect households saving electricity behavior is by increasing their motivation, knowledge, and access to information about saving electricity programs. RQ6: From the classification of household segments, which class is the most involved in saving electricity? H6: From the classification of household segments, class R1:2.200VA is the most involved in saving electricity. Conceptual Framework Source: Author (Adapted from Kotler, 1999, and deGroot Steg, 2009) Figure 3.: Conceptual Framework Research Data Type and Source of Data There are two types of data that researches collected depending on the purpose. The data of research consists of both primary and secondary data. The primary data are the first-hand information acquired by the researcher on the variables under study while the secondary data refer to information gathered from sources that already exist which may come from archives or organizational files (Sekaran Bougie, 2009, p. 180). This research was used both primary and secondary data. The primary data sources were obtained through the survey method by distributing structured questionnaires to household customers of PT. PLN Jakarta Raya and Tangerang Distribution. The secondary data were obtained from the company internal data such as figures in customer-base segmentation, and existing data in books, journals, publications, reports, and websites. Data Collection Method The data collection for primary and secondary data is done through the following methods: Literature Review. According to Sekaran and Bougie (2009, p. 38), a literature review is a step-by-step process that involves the identification of published and unpublished work from secondary data sources on the topic of interest, the evaluation of this work in relation to the problem. In this research, the literature review is done by search and study books, reports, journals, research reports, internet website related to electricity business and customer behavior. The information related to the company is obtained through the companys website and published reports. Questionnaire. Sekaran and Bougie (2009, p. 197) define questionnaire is a pre-formulated recorded series of questions to which the respondents giving their answers usually within rather closely defined alternatives. For this research, the questionnaire is formulated and distributed to the respondents in two methods. First method used is by distributing the questionnaire to respondents through email. The second method is the direct questionnaire to respondents, by asking them to give their answer on the questionnaire paper provided. Questionnaire Design Questionnaires are efficient data collection method when the researcher knows the information to gather and how to determine the variables of interest (Sekaran Bougie, 2009, p. 197). Questionnaire survey is formulated to answer the research questions. It is a tool that may be conveniently distributed personally or electronically to respondent. According to Burns and Bush (2006, p. 300), there are six key functions of a questionnaire: To translate the research objectives into specific questions. To standardize the questions and the response categories to let every participant responds to identical stimuli. To reinforce cooperation and motivates respondents to respond. To serve as permanent records of the research. To speed up the process of data analysis, depending on the type of questionnaire used by the researcher. To contain the data which may be addressed for reliability and validity. The first part consists of the demographic attributes questions such as gender, age, education, occupation, annual income, and the second part consists of questions analyzing customer behavior in terms of cultural, social, personal, and psychological factors that base on Griffin and Eberts model (2006, p. 283). Part two in the questionnaires use Likerts scale which enables the respondents to give level of the attributes stated in the questions. A Likerts scale was used in the research, in which respondents were asked to indicate their level of agreement or disagreement on a systematic agree-disagree scale for each of a series of questions (Burns Bush, 2006, p. 281). Each question in the questionnaire on this part is ranged from 1 to 5, where 1 = Strongly Disagree; 2 = Disagree ; 3 = Neutral or Not Applicable ; 4 = Agree ; 5 = Strong Agree. The questionnaire format for this research is shown in Figure 3.3 below. Source: Author Figure 3.: Questionnaire Design for This Research Table 3.1 shows the distribution of items in order to measure the variables in the questionnaires.

Cultural Factors Regularly using electricity at peak load hours (between 17.00 to 20.00). Household activities were dominated by using electrical equipment. Regularly using electrical equipment in day time. B. Social Factors The capacity of installed electricity is in accordance with the requirement. Able to pay if electricity tariff is go up. Electricity tariffs are still cheap. Its normal to reduce electricity subsidized and to increase tariffs when oil prices are up. C. Personal Factors Able to pay electricity and can afford the electricity bills. It is necessary to increase capacity because the need of electricity will increase. Electricity bills are relatively small compare to the total expenditure. D. Psychological Factor When using electricity at peak time, we will pay more expensive. Feeling guilty when using electricity at peak time. Feeling happy if every rooms are bright. E. PLN Services Power failure was rarely, so it is convenient to use it, especially at peak time. Recording of electricity is on time and the bill is in accordance with the use. Since electricity is stable, we are not worry to use it at peak time. Part 2: Exploratory Questions (Data are in Likert scale) Customer behavior towards saving electricity No. Variables Category of Questions A. Access to Information Get information about saving electricity from friends, family, neighbor, PLN, or community leaders. Get information about saving electricity from television, radio, magazine/newspaper, and internet. Often receiving information about saving electricity. B. Knowledge Knows electricity-saving equipment. Electrical equipment will be more efficient when turned off than in standby. Using electrical equipment at its maximum capacity will take more energy. C. Motivation Being motivated to prioritize electricity saving behavior. Being motivated to respect environment. D. Pro-social Intensions There are negative consequences of any actions that do not respect the environment. Feel responsible for environmental damage. Having a moral obligation towards energy efficiency and environmental protection. Questionnaire Format In this research, the questionnaires were prepared in printed and online formats using Indonesian language, because some of the respondents were not able to read and speak in English language. During the pre-test stage, the questionnaire was distributed only through email to 30 respondents to find out the validity and reliability of the data or questions in the questionnaires. At the post-test stage, the revised questionnaire was printed and distributed door to door. Due to time limitation, researcher employed a strategy by setting up a team consist of 6 (six) members to meet the respondents in 6 (six) different locations (domiciles). The revised questionnaire was also distributed by email. By using email, it was very convenient in terms of shortening the time spent to send the questionnaire and receiving the responses from the respondents. However, there were difficulties because the respondents were depended on a computer and internet service. Survey Sampling Method According to Sekaran and Bougie (2009, pp. 262-263), a sample is a subset of the population. It comprises some members selected from it. A sample is thus a subgroup of the population, which represents the whole group of people, actions, or things of interest that the researcher wants to investigate. According to Burns and Bush (2006, pp. 372-374), the size of the sample affect the sample accuracy of results, thus sample accuracy refers to how close a random samples statistic is to the populations value it represents. The most correct method of determining sample size is confidence interval approach. In order to calculate the proper sample size of the survey, Burns and Bush (2006, p. 366) said, there are three items required: Amount of variability of population Desired accuracy, and Required confidence level. Sampling Methodology In this research, the population is the total number of customers of PT. PLN Jakarta Raya and Tangerang Distribution from the Household segment, which according to the statistics are 3.330.815 number of customers. For this amount of population, the sample size may be calculated using the formula recommended by Burns and Bush (2006, p. 372): Where: n = the sample size z = standard error associated with the chosen level of confidence (1.96) p = estimated percentage in the population q = 100- p e = acceptable sample error Sample population sample size = population sample size x In this research, researcher chose to use a probability of 90% with a 95% level of significance equivalent to a z value of 1.96 and sample error 4%. The sampling calculation was determined by using a software application, PHStat2. PHStat2 is a Windows-based software that assists students and professionals in learning the statistic concepts while using Microsoft Excel. Table 3.: Sampling Size Determination Data Estimate of True Proportion 0.9 Sampling Error 0.04 Confidence Level 95% Intermediate Calculations Z Value -1.95996398 Calculated Sample Size 216.0820587 Result Sample Size Needed 217 Finite Populations Population Size 3.330.815 Calculated Sample Size 216.0681064 Sample Size Needed 217 Source : Data on File Based on the calculation in Table 3.2, the minimum number of sample size needed is 217 samples; however in this research the number of samples is added to another 10 percent in order to produce greater accuracy. Therefore, this research will be used 240 samples. This research will use a cross sectional-study in which the data are gathered at once in order to answer the research questions (Sekaran Bougie, 2009, p. 119). Sample Withdrawal Techniques The populations in this research were household customers of PT. PLN Jakarta Raya Tangerang Distribution. Sampling technique was done by using stratified random sampling, involves a process of stratification or segregation, followed by random selection of subjects from each stratum. The population is divided into stratum, and then sampling conducted in each stratum (Sekaran Bougie, 2009, p. 272). In this research, customers who become household population were stratified based on electrical power and is divided into three groups, namely: 900VA, 1.300VA and 2.200VA. It is based on the Regulation of the President of Republic Indonesia No. 8, 2011, p. 9 (see Appendix A2). The sample selection techniques are described in Figure 3.4. Source: Author Figure 3.: Sample Withdrawal Techniques Data Analysis After data are obtained through questionnaires, the next step is to analyze them to test the research hypothesis. To ensure that the data obtained are reasonably good and ready for use for statistical analysis, Sekaran and Bougie (2009, pp. 306-330) recommend followings: Getting the data to be ready for analysis: Coding and data entry Coding the responses Data entry Editing data Data transformation Getting a feel for the data: Relationship between variables Correlations Testing goodness of data Reliability Validity Testing the hypothesis Hypothesis testing and data analysis will be conducted using appropriate statistical method and based on sample data associated with software such as PHStat2, SPSS version 20, and AMOS version 20. Descriptive Analysis Descriptive analysis such as the mean, mode, standard deviation, and range are used by researcher to describe the sample data matrix in such a way as to portray the typical respondent and to reveal the general pattern of responses. Descriptive measures are regarded as the steps undertaken by the researcher earlier in the process of analysis and become foundations for subsequent or more complex analysis (Burns Bush, 2006, p. 424). Descriptive statistics were used to portray the main characteristics of a collection of data in quantitative terms and distinguished from inductive statistics in that they intend to quantitatively review a data set, instead of being used to support reports regarding the population that the data are supposed to represent. Even when a data analysis obtains its major conclusions using inductive statistical analysis, the descriptive statistics are usually presented alongside the formal analyses to show the audience an overall perception of how data being examined. Validity and Reliability Test A good quality measurement instrument is needed in order to obtain precise data of this research. The ideal instrument has to be reliable and valid. The researcher must address both validity and reliability of the measures in assessing the degree of measurement error present in any measures. Any measure designed or adapted for use in any research should both be reliable and valid. A reliable measure is one in which a respondent acts in response to the same or a very similar manner to an identical or nearly identical question (Burns Bush, 2006, p. 290). The reliability of a measure is a test of how consistently a measuring instrument measures whatever concept it is measuring. In testing the reliability of the questionnaire, the test-retest reliability test was used which measures the correlation between the same respondents obtained at the two different times (Sekaran, 2010, p. 162). To achieve reliability of a measure, the researcher was using SPSS software with Cronbachs Alpha as the measurement. Cronbachs Alpha is a reliability coefficient that determines how well specific items of the measurement tools are positively correlated to one another. Cronbachs Alpha is computed using the average intercorrelations among the items measuring the concepts. If Cronbachs Alpha is greater than 0.70, it means that the data are more consistent and reliable. The closer the alpha value to 1 indicates the data are most consistent and reliable. A high quality reliable instrument can be used as a guide to draw a conclusion and making decisions (Sekaran Bougie, 2009, pp. 324-325). Validity is a test of how fine a developed instrument to measure the particular concept it is planned to measure. In the other words, validity is related to measurement with the right concept and reliability with stability and consistency of measurement (Sekaran Bougie, 2009, pp. 158-160). Correlation Analysis Correlation analysis is an analysis done to trace the mutual influence of variables on one another. A correlation coefficient that indicates the strength and direction of the relationship can be computed by applying a formula. There could be a perfect positive correlation between two variables, which is represented by 1.0 (plus 1), or a perfect negative correlation which would be -1.0 (minus 1) (Sekaran Bougie, 2009, p. 322). The formula to calculate the coefficient of correlation is: Source: Burns Bush, 2005 Where: r = coefficient correlation n = samples xi = variable X x = mean X yi = variable Y y = mean Y Table 3.3 presents the rules of thumb in interpreting the correlation coefficient values. Table 3.: Rules of thumb of degree of correlation Coefficient Range Strength of Association  ±0.81 to  ±1.00 Strong  ±0.61 to  ±0.80 Moderate  ±0.41 to  ±0.60 Weak  ±0.21 to  ±0.40 Very Weak  ±0.01 to  ±0.20 None Source: Burns Bush, 2005 Structural Equation Modeling (SEM) Structural equation modeling (SEM) is a statistical approach for testing and estimating causal relationship using a combination of statistical data and qualitative causal assumptions. Typically, this theory represents causal processes that produce examinations on multiple variables. The term structural equation modeling expresses two important features of the procedure: causal processes, represented by a sequences of structural (i.e. regression) equations, and these structural relationships can be displayed pictorially to allow a clearer conceptualization of the theory. Then, the hypothesized model can be examined statistically in a simultaneous analysis of the entire variables to conclude the degree of its consistency to the data. If goodness-of-fit is adequate, the model argues for the credibility of hypothesized relations among variables. If it is inadequate, the reasonability of those relations is rejected (Byrne, 2010, p. 3). Statistical models provide an efficient and convenient way of describing the latent structure underlying a set of observed variables. Expressed either diagrammatically or mathematically via a set of equations, such models explain how the observed and latent variables are related to one another. Typically, a researcher postulates a statistical model based on his or her knowledge of the related theory, on empirical research in the area of study, or on some combination of both. Once the model is specified, the researcher then tests its plausibility based on sample data that comprise all observed variables in the model. The primary task in this model-testing procedure is to determine the goodness-of-fit between the hypothesized model and the sample data. As such, the researcher imposes the structure of the hypothesized model of the sample data, and then tests how well the observed data fit this restricted structure. Because it is highly unlikely that a perfect fit will exist between the observed data and the hypothesized model, there will necessarily be a differential between the two; this differential is termed the residual. The model-fitting process can therefore be summarized as follows: Data = Model + Residual Where: Data represent score measurements related to the observed variables as derived from persons comprising the sample. Model represents the hypothesized structure linking the observed variables to the latent variables and, in some models, linking particular latent variables to one another. Residual represents the discrepancy between the hypothesized model and the observed data (Byrne, 2010, p. 7). Structural equation models are schematically portrayed using particular configurations of four geometric symbols: a circle (or ellipse), a square (or rectangle), a single-headed arrow, and a double-headed arrow. By convention, circles (or ellipses; ) represent unobserved latent factors, squares (or rectangles; ) represent observed variables, single-headed arrows (à ¢Ã¢â‚¬  Ã¢â‚¬â„¢) represent the impact of one variable on another, and double-headed arrows (à ¢Ã¢â‚¬  Ã¢â‚¬ ) represent covariance or correlations between pairs of variables (Byrne, 2010, p. 9). In building a model of a particular structure in this research, the researcher uses these symbols within the framework of four basic configurations, each of which represents an important component in the analytic process. These configurations, each accompanied by a brief description, are as follows: Path coefficient for regression of an observed variable onto an unobserved latent variable (or factor) Path coefficient for regression of one factor onto another factor Measurement error associated with an observed variable Residual error in the prediction of an unobserved factor The Path Diagram Schematic representations of models are termed path diagrams because they provide a visual portrayal of relations which are assumed to hold among the variables under study. Essentially, a path diagram depicting a particular SEM model is actually the graphical equivalent of its mathematical representation whereby a set of equations relates dependent variables to their explanatory variables (Byrne, 2010, p. 10). Using path diagram as a structural equation modeling tool, the pattern of causal relationship can be detected. Causal relationship describes interrelations among a set of latent (unobserved) variables and a set of observed variables. Path diagram is a relationship structure between the exogenous and endogenous variables. The independent (X) variables are called exogenous variables. The dependent (Y) variables are called endogenous variables. Model Measurement According to Hair et.al (2010) measurement model validity depends on establishing acceptable levels of goodness of fit (GOF) for the measurement which indicates how well specify model reproduces the observed covariance matrices, smaller the difference between covariance matrices estimate with the observe covariance matrices, more fit the model. (Hair et. al, 2010, p.639). The GOF value contains several parameters to be considered by the researcher as stated by Hair et.al (2010, p.640-650), this thesis confirm the overall model fit the parameter will used the following: Chi-square (CMIN) or minimum discrepancy (), it is to test whether there is the different covariance matrices estimate within the covariance matrices observe, smaller () shown the different of both not significant and the model more fit. df (degree of freedom), more positive (>=0) of the df which shown with minimum was achieved the process of the estimate could be done. CMIN/DF. CMIN represents the minimum value of the discrepancy while DF is the degree of freedom. According to Wijaya (2009, p. 45), the model could be accepted if the CMIN/DF is à ¢Ã¢â‚¬ °Ã‚ ¤ 2.00. RMR (root mean square residual), this is called badness of fit whether the value is less than 0.1 than it is better because deference between sample and the estimate is smaller (Hair et.al 2010, p.642) GFI and AGFI (Goodness fit index and Adjusted Goodness fit index), GFI and AGFI value between 0 to 1, more closed to 1 more fit the model (Hair et.al 2010, p.643)

Employment Law Essay examples -- Law

Introduction In many countries the state’s role in employment relations is not something that can be ignored. The state, which is characterized by a set of institutions made of the executive, legislature, the judiciary, the local government and the police, is a system of political domination that exercises power with the legitimate usage of violence, money supply and taxation. The presence of the state in any aspect of life of its citizens is pervasive, whether it is through macroeconomic policies or its role as an employer or even through legislation. In the capitalist world we live in today the state cannot be left out in any aspect pertaining to its citizens. The state (government) is applying policies on the basis that other participants in the employment relations system (employers and the trade unions) cannot manage to take control of all the aspects involved in the work system (Palmer, 2007). Since the federal elections of 2004, the policy of industrial relations issue has been all over. The competing goals of the employees and employers are evident through the trade unions and third parties. The managements’ objectives are paramount with regards to market efficiency with limited space for other interests. Therefore, curtailing trade unions’ activities and setting tribunals to regulate conditions and wages in the name of free markets is increasing. The states talks of advocating for democracy, having limited interventions s as to bring about industrial harmony in certain sectors of the economy, but in practice it has intervened in almost all the sectors of the economy (Adams, 200 ). This therefore begs the question, should the state play an intervening role in employment relations, and if so, to what extent and why? .. ...the sectoral and national interests are integrated to increase productivity. The collective bargaining system should also be independent to develop a more equitable and balanced tripartite relationship (Adams, 2001). Works Cited Adams, J.

Evolution & Creationism in Education Essay examples -- Teaching God Cr

Evolution & Creationism in Education The twentieth century has witnessed the escalation of the creation - evolution debate through famous court cases and Supreme Court decisions on the teaching of evolution in public schools, culminating most recently in a Kansas Board of Education decision. As this highly controversial issue of the teaching of evolution in American classrooms rages on, it may be difficult for some individuals of Christian faith to form an alternative belief other than the extremes of creationism and evolutionism. Before discussing this issue any further, when I refer to strict beliefs in creationism or evolution as extreme views I am not necessarily implying that they are wrong, but are simply two views on completely opposite sides of the creation - evolution debate spectrum.

Evolution & Creationism in Education Essay examples -- Teaching God Cr Evolution & Creationism in Education The twentieth century has witnessed the escalation of the creation - evolution debate through famous court cases and Supreme Court decisions on the teaching of evolution in public schools, culminating most recently in a Kansas Board of Education decision. As this highly controversial issue of the teaching of evolution in American classrooms rages on, it may be difficult for some individuals of Christian faith to form an alternative belief other than the extremes of creationism and evolutionism. Before discussing this issue any further, when I refer to strict beliefs in creationism or evolution as extreme views I am not necessarily implying that they are wrong, but are simply two views on completely opposite sides of the creation - evolution debate spectrum. For some creationists, accepting God as Creator as told in the Book of Genesis means the simultaneous rejection of evolutionary theory.

How to Lie with Statistics

A Synopsis of How to Lie with Statistics by Darrell Huff When most people hear or read a statistic, they quickly have to decide if the numbers listed are valid or invalid. It is usually assumed that the author of the statistic is knowledgeable in the field to which the statistic pertains. However, on many occasions, the statistic is false, due to the author’s wording. Darrell Huff’s novel How to Lie with Statistics is a manual that can help individuals catch these lies. The novel allows readers to solve marketing ploys and dismiss certain statistics as faulty.The first chapter focuses on bias. The book states that all statistics are based on samples, and these samples have bias. This means that no matter what the reader will have a biased opinion. This bias is spawned from the respondents replying dishonesty, the author choosing a sample that gives better results, and the availability of data. Huff uses a survey of readership of two magazines, which had refuting results . This is because, due to the readers’ personal biases, they answered the survey dishonestly.This example closes the chapter, teaching readers to always assume that the sample has a bias. The second chapter focuses on averages. It states that there are actually three types of averages: mean, median, and mode. Mean is the arithmetic average. Median is the name given to the midpoint of the date. Finally, mode is the data point that occurs the most often in the data. Thus, the type of average used can alter the results of the statistics. The next chapter explains how sample data is chosen to prove certain results.Many marketing campaigns use this technique. They choose sample sizes that give their wanted results. Huff’s solution is that one must determine if the information is a discrete quantity or if a range is involved. The following chapter discusses errors in measurement. It explains two measures for measuring error: Probable Error and Standard Error. The probable er ror uses the error in the measuring device used to measure the error in the measurement. The standard error is the standard deviation of the sampling distribution of a statistic.Chapter five explains how to manipulate a graph in order to show the results one wants. For example, if one was using a line graph to show a 10% climb, they could remove the unused parts of the graph to make their results seem more extreme. The next chapter discusses how two-dimensional images can deceive readers. A picture may be increased in all dimensions, making it seem much larger than it really is, giving the impression of a greater increase. Chapter seven focuses on the semi-attached figure.Simply put, if one cannot prove what they wish to prove, they can merely prove something else and then give the impression that these two things are the same. Huff uses cold medicine as an example. A pharmacist wants the reader to believe that their medicine cures the cold, but instead the label reads that the medi cine kills 32, 132 cold germs. The pharmacist then hopes that the reader makes the assumption that because the medicine kills such a high number of germs, then it cures the cold. Huff is therefore teaching not to assume.The following chapter focuses on cause and effect. Huff stresses that readers must ask for when certain data was collected and if the amount of data was adequate for the entirety of the experiment. Chapter nine teachers readers how to ‘statisticulate’, meaning how to manipulate readers by using statistics. This chapter is essentially a list of what to look for when determining the validity of a statistic. Huff explains various tricks, such as measuring profit on a cost price and how income calculations mislead by using children of a family as the average.The final chapter instructs readers on how to talk back to a statistic. Huff emphasizes that readers must ask who the author his and how did he come to collect the knowledge listed in the statistic. Also , he encourages readers to question if someone changed the subject of the statistic. Finally, he explains that one must be able to understand the data presented, and if it does not make sense, then it is most likely untrue. Overall, Huff assists readers in how to determine if a statistic is valid or invalid. Though the book was published over fifty years ago, these methods are still in use.

Hong Kong Waste Problem

Hong Kong has an imminent waste problem. Here you can learn about what municipal solid waste is, how significant our waste problem is, and how the Government tackles the problem. The Waste Problem Hong Kong generates several types of solid waste. It includes municipal solid waste (MSW), which comes from domestic, commercial and industrial sources; construction waste, which arises from construction, renovation and demolition activities; and other special wastes such as chemical waste and livestock waste. †¢ More on waste in Hong Konghttp://www. epd. gov. k/epd/english/environmentinhk/waste/waste_maincontent. html Municipal Solid Waste Municipal solid waste includes waste from domestic premises and public facilities, commerce and some types of industry, but excludes construction waste and chemical waste. Each year, more than 6 million tonnes of MSW are generated, over half of which is disposed of in the three strategic landfills. Unfortunately, the generation of MSW has been growing at a much faster rate than expected, and our consumption-led lifestyle is putting enormous pressure on these landfills. The three existing landfills will be full, one by one, in the mid to late 2010s. If the waste loads continue to increase, there will be a need to allocate an additional 400 hectares of land to develop new landfill sites to meet our waste disposal needs up to 2030. Clearly, Hong Kong needs a more sustainable way to deal with waste. To address our waste problem, the Government published â€Å"A Policy Framework for the Management of MSW (2005-2014)† (Policy Framework) in December 2005. The Policy Framework sets out a comprehensive strategy for the management of MSW in the next 10 years. It consists of a series of policy tools and measures to tackle the waste problem head on. †¢ More on municipal solid wastehttp://www. gov. hk/en/residents/environment/msw. htm †¢ Information on the Policy Framework for the Management of Municipal Solid Waste (2005-2014)http://www. epd. gov. hk/epd/msw/htm_en/content. htm Construction Waste The high levels of construction activity in Hong Kong generate equally high levels of inert or recyclable waste and non-inert or organic waste. Both hese forms of waste pose challenges to the maintenance of our landfill programme, and need to be managed carefully. Under the polluter-pays principle, the Environmental Protection Department operates the Construction Waste Disposal Charging Scheme, whereby construction waste producers pay appropriate charges for the disposal of their waste. The Government is also encouraging the industry to sort and recycle waste as far as possible, and to plan and build more efficiently to minimise waste. Mo re on construction wastehttp://www. gov. hk/en/residents/environment/constructionwaste. htm Waste Reduction and Recycling You can participate in a number of waste reduction programmes. The Wastewi$e Label under the Hong Kong Awards for Environmental Excellence, for example, helps Hong Kong businesses and organisations in adopting measures to reduce the amount of waste generated within their establishments or through the products and services they provide. It provides members with free advice on waste management techniques and rewards their efforts through public recognition. You can also help the recycling of domestic waste by participating in the Programme on Source Separation of Domestic Waste and separating waste using the waste separation bins on housing estates and deposit rechargeable batteries in designated collection boxes. †¢ More on waste reduction and recyclinghttp://www. gov. hk/en/residents/environment/wasteredrecyc. htm
