Experimental Parameters

The role of statistics in certain areas of X-ray fluorescence analysis is considered. The topics discussed include: calculating the standard deviation associated with the result of an analysis; optimizing experimental parameters for both wavelength and energy dispersive analyses; evaluating limits of detection, limits of decision, and limits of determination; and weighting in the least squares fitting of data in single element polynomial relationships and in multi-element multiple regression analysis.

This research aims to analyze the factors that influence the role of Small and Medium Enterprises (SMEs) on employment, namely capital, sales volume, type of business, length of business, and wages. Empirical data is presented to prove that the role of small and medium enterprises on employment is influenced by capital, sales volume, type of business, length of business, and wages. Multiple regression analysis through the SPSS program was used as a research test tool. The research data was obtained from SMEs businesses, Central Bureau of Statistics and the SMEs Office to test scientifically whether capital, sales volume, type of business, duration of business, and wages affect employment. Research results show that the duration of the business influences the absorption of labor while capital, sales volume, type of business, and wages do not affect employment. Keywords: SMEs, capital, sales volume, type of business, length of business, wages

Demand Structure

Data collected by a local authority housing department are analysed in order to test a model forecasting the annual number of households moving out into owner occupation. The reduced form of the model is estimated by means of ordinary least squares multiple regression analysis, and the demand structure is estimated by means of two-stage least squares for comparison. Despite problems of autocorrelation the results are sensible and suggest that further work on these lines is likely to be worthwhile not least for a local authority involved in planning the housing requirements of a region.

Set Up

A method for the quantitative determination of the major constituents in laterites and bauxites by x-ray fluorescence using fused Na2B4O7 glass discs is presented. The calibration curves were set up employing synthetic mixtures of oxides of Si, Al, Ti, and Fe. The interelement effects were corrected using a multiple regression analysis programed on a PDP 11/45 computer. The precision was determined by preparation and analysis of five synthetic pellets; the accuracy was ascertained by analysis of five international standards.

Workplace Incivility

This study aims to investigate and analyze the role of organizational context on workplace incivility and turnover intention. The research sample was 120 employees who work at the company engaged in the service industry. Multiple regression analysis was used to test the research hypotheses. The results found that organizational context influences workplace incivility, which in turn increases turnover intention. As a consequence, it is important for the organization to enhance alertness towards the occurrence of the employees’ workplace incivility. Internalization and implementation of values of the organizational context can be utilized to manage employees’ work performance

This research aims to find out the role of community and village empowerment agencies in the development of BUMDes in North Labuhanbatu Regency. As an office that handles about villages, community and village empowerment agencies have the task of carrying out training, coaching, and mentoring to the development of BUMDes. The formulation of this research problem is "whether the role of training, coaching and mentoring affects bumdes development in North Labuhanbatu Regency. In this study, data was collected through questionnaire methods of 74 BUMDes administrators to find out respondents' responses to each variable. Then an analysis of the data obtained in the form of validity and rehabilitation tests, classical assumption tests, multiple regression analysis, simultaneous hypothesis tests, partial hypothesis tests and coefficients of determination. The results of this study are: partial test that the variables of training, coaching and mentoring have a positive and significant effect on the development of BUMDes, while simultaneous tests that the variables of training, coaching and mentoring together have a significant effect on the development of BUMDes in North Labuhanbatu Regency.

ABSTRACTThis study aims to see the effect of perceptions received by tourists visiting intention to Toba Lake, Samosir Regency. A quantitative approach method was used by using statistical data in multiple regression analysis. The population was domestic tourists and the sample was 325 respondents who were obtained using random sampling techniques. The results were divided into (1) a significant effect and positive destination accessibility and simultaneously on the intention in tourist visits 2) the ability of the independent variables in explaining the related variables was 53.8% the remaining 46.2% from other variables not discussed in this study 3) the influence of accessibility variable on tourists' visiting intention is strong. From these results it can be concluded that accessibility according to the Apollo concept needs to be improved by the manager of tourist destinations at Toba Lake because the role of accessibility affects the intention to visit tourists to Toba Lake. Keywords: Real Accessibility, Destination Accessibility, and Visiting Intention

The Relationship

Generally, manufacturing capability is the important factor in running and developing business. Hence, this research is aimed to identifying the relationships of critical factors and make sure the companies can survive in the northern region of Malaysia. Those identified factors are training and manufacturing capabilities. Through the email survey, a total of 89 companies representing electrical and electronic industries had responded. The hypotheses involved were tested using correlation and regression techniques. The results of the study support all the hypotheses. The multiple regression analysis indicates that there are significant relationships among the factors on each criterion to manufacturing capabilities. While hierarchical multiple regression analysis was carried out to test the role of moderating in the relationship between independent variables with dependent variables. It is believed that results of this study will be beneficial for shareholders and directors of companies to apply these manufacturing capabilities.
