An inventory of scale items for a tailormade semantic differential is developed to measure the image of nonprofit voluntary organizations. The sixty-three items yield twelve first-order factors. Second-order factor analysis provides unifying constructs within the domain of voluntary organizations’ image. Coefficient alpha reliability estimates indicate a highly reliable measurement scale.

This study was conducted to construct and validate an EFL teachers’ attitudes towards classroom observation scale in the context of Iran. For this purpose, one hundred EFL teachers, who were teaching English in Jahan Elm, Institute of Higher Education and Hafez English Language Institute, Mashhad, Iran, were asked to participate in the study and fill in the questionnaire. First, the internal consistency of the instrument as measured by Cronbach’s coefficient alpha reliability reached acceptable alpha(s). Then, Confirmatory Factor Analyses (CFAs) were conducted using LISREL 8.80. The results of the CFA as assessed by the CFI/NNFI, RMSEA and chi-x2, reached acceptable fits. The factor structures were defined and the factors were clearly distinguishable from one another. Based on the findings, the researchers concluded that the present scale has undoubtedly strong psychometric characteristics and good construct validity which is useful for assessing EFL teachers’ views on classroom observation in Iran.

This study applied SERVQUAL scale of Parasuraman et al to measure factors affecting customer satisfaction on service quality at Vietnam Technological and Commercial Joint Stock Bank - An Giang Branch (Techcombank An Giang). The study was conducted to survey 207 customers who have been using the service at Techcombank An Giang. The survey results were analyzed by the Cronbach's Alpha reliability test method, then used Exploratory factor analysis (EFA) to verify and evaluate the scale of service quality. The results of the regression analysis show that customer's satisfaction about service quality at Techcombank An Giang includes four factors: The factor with the highest level is the Empathy with Beta = 0.253, the second of factor is the Responsibility with Beta = 0.248, ranked third in the influence level is the Tangible with Beta = 0.235, and the lowest impact level is the Reliability with Beta = 0.144. The research also uses statistical methods to describe and test the differences of demographic factors with customer's satisfactionon service quality.The analysis results show that there is no difference between customer's satisfaction on service quality and factors such as gender, age, income, number of transaction banks, regular transaction banks, and time to use the service at Techcombank An Giang. Through the research results, the author would like to propose some ideas to improve the quality of services, thereby attracting new customers and importantly, keeping traditional customers because the development orientation of Techcombank is to take care of old customers to cross sell other products of the bank. The Stud results offer a basis for the branch to identify the factors influencing customer satisfaction on their service quality, thereby having an appropriate strategy to improve customer satisfaction.

Descriptive Survey

This study was carried out to determine the modern office technology competencies expected of office technology and management (OTM) graduate workers by supervisors in Delta State. The study was guided by two research questions and two hypotheses tested at 0.05 level of significance. The respondents consisted of 142 supervisors, made up of 74 heads of department and directors of government establishments, and 68 managers and directors of private establishments in the study area. Descriptive survey research design was used to conduct the study and 28 – items questionnaire were used to collect data from respondents. The instrument was validated by three experts and had a Cronbach Alpha reliability coefficient of 0.77. Means with standard deviations were used to answer the research questions, while t-test was used to test the null hypotheses. The extent of supervisor‟s expectations of information processing competencies did not differ significantly based on the mean ratings of male and female supervisors of OTM graduates in government and private establishments. The findings also revealed that supervisors expect much information processing and communication competencies from the OTM graduate workers. Based on the findings and the implications, it was recommended among others that, curriculum planners, business and OTM education lecturers should ensure that the competencies required for modern office technologies are entrenched and taught in the institutions to prepare the OTM graduates for the world of work.
