The successful implementation of e-government transformation: A case study in Oman

The aim of this paper is to investigate, and to discuss the key critical factors that facilitate the successful implementation of E-government projects. The nature of this research is mainly qualitative. This investigation uses a single case study and data was mainly collected by means of semi-structured interviews and organisational documents from the Ministry of Higher Education in Oman. The research findings suggest that there are three paradigms which each include a set of factors that impacts the success of E-government success namely, organisational paradigm, technology paradigm and end-users paradigm. The authors believe that, this paper demonstrates an added value to the current literature on transformation of E-government and to E-government projects success, within the wider context of E-government implementation projects. Also the research will benefit organisations in the public sector, as it has identified main key success factors in E-government transformations and implementations

Critical success factors in ERP implementation: A review

ERP systems have become vital strategic tools in today’s competitive business environment. This ongoing research study presents a review of recent research work in ERP systems. It attempts to identify the main benefits of ERP systems, the drawbacks and the critical success factors for implementation discussed in the relevant literature. The findings revealed that despite some organizations have faced challenges undertaking ERP implementations, many others have enjoyed the benefits that the systems have brought to the organizations. ERP system facilitates the smooth flow of common functional information and practices across the entire organization. In addition, it improves the performance of the supply chain and reduces the cycle times. However, without top management support, having appropriate business plan and vision, re-engineering business process, effective project management, user involvement and education and training, organizations can not embrace the full benefits of such complex system and the risk of failure might be at high level

HR performance within Saudi Arabian organisations : is the relationship between 'job security and ill-treatment' and job satisfaction moderated by organisational support : a thesis presented in partial fulfilment of the requirement for the degree of Master of Business Studies in Management at Massey University, Albany, New Zealand

HR performance, particularly employees’ performance, has been well researched in Western countries. However, many Asian countries, including the region of the Arabic Gulf, are still under-researched in relation to this subject. This present study quantitatively investigated employees’ performance in one of the Gulf countries, Saudi Arabia. In addition, it took into consideration the religion (Islam) as well as the cultural characteristics that may affect performance in the workplace. Particularly, the type of society (collectivistic), losing face issue and power distance are the cultural characteristics discussed in this study. Furthermore, the study used four variables, which are considered important in relation to employees’ performance in the Saudi context: job security, ill-treatment (independent variables), perceived organisational support (POS) as a moderating variable and job satisfaction (dependent/outcome variable). The research question for this study is “Is the relationship between job security and ill-treatment, and job satisfaction, moderated by organisational support?” Previous research indicates that relationships between these variables vary in terms of how much they impact employees’ job satisfaction and, therefore, their performance. Some studies suggest that job security increases employees’ job satisfaction which can result in better performance. Others claim that ill-treatment can be a source of job dissatisfaction and lower the quality of job performance as ill-treatment impacts employees physically and psychologically. In addition, POS was found to have positive effects on job satisfaction as a higher level of support from organisations can lead to higher job satisfaction and performance. This cross-sectional, quantitative study used a questionnaire as the data collection method. Measurement scales used in the study were previously used in other studies, which strengthens the internal validity of this study. The 424 participants who completed the survey were Saudi employees who were required to have worked for at least six months for the same employer as full-time employees in Saudi Arabia. Results from this study suggest that, on an individual level, all three variables (job security, ill-treatment, POS) predicted job satisfaction in Saudi organisations. However, the regression analysis showed that job security had the biggest effect on job satisfaction followed by ill-treatment. Also, the moderation analysis revealed that the relationship between job security and job satisfaction was partially moderated by POS. However, POS did not appear to moderate the relationship between ill-treatment and job satisfaction

Properties of estimators of parameters in logistic regression models

Properties of various types of estimators of the regression coefficients in linear logistic regression models are considered. The estimators include those based on maximum likelihood, minimum chi-square and weighted least squares. Theoretical approximations to the biases of the estimators are developed. The results of a large scale simulation investigation evaluating the moment properties of the estimators are presented for the case of a logistic model with a single explanatory variable

The extreme residuals in logistic regression models

Goodness of fit tests for logistic regression models using extreme residuals are considered. Moment properties of the Pearson residuals are developed and used to define modified residuals, for the cases when the model fit is made by maximum likelihood, minimum chi-square and weighted least squares. Approximations to the critical values of the extreme statistics based on the ordinary and modified Pearson residuals are developed and assessed for the case when the logistic regression model has a single explanatory variable

Null distribution of some goodness of fit statistics for logistic regression

The null distribution moment and percentile properties of several goodness of fit statistics for logistic regression models are considered. Small sample approximations to the critical values of the statistics are evaluated for the case of a single explanatory variable with equally spaced values

Certain triple q-integral equations involving third Jackson qq-Bessel functions as kernel

In this paper, we employ the fractional $q$-calculus in solving a triple system of $q$-Integral equations, where the kernel is the third Jackson $q$-Bessel functions. The solution is reduced to two simultaneous Fredholm $q$-integral equation of the second kind. Examples are included. We also apply a result in~[Pacific J. Math. \textbf{275}(1) (2015)63--102] for solutions of dual $q^2$-integral equations to solve certain triple integral equations
