Abstract. The aim of this study was to investigate the relationship between the flight-related core competencies for professional airline pilots and to structuralize them as components in a team performance framework. To achieve this, the core competency scores from a total of 2,560 OPC (Operator Proficiency Check) missions were analyzed. A principal component analysis (PCA) of pilots’ performance scores across the different competencies was conducted. Four principal components were extracted and a path analysis model was constructed on the basis of these factors. The path analysis utilizing the core competencies extracted adopted an input–process–output’ (IPO) model of team performance related directly to the activities on the flight deck. The results of the PCA and the path analysis strongly supported the proposed IPO model.

Confirmatory Factor

Abstract. Factorial validity is often assessed using confirmatory factor analysis. Model fit is commonly evaluated using the cutoff values for the fit indices proposed by Hu and Bentler (1999) . There is a body of research showing that those cutoff values cannot be generalized. Model fit does not only depend on the severity of misspecification, but also on nuisance parameters, which are independent of the misspecification. Using a simulation study, we demonstrate their influence on measures of model fit. We specified a severe misspecification, omitting a second factor, which signifies factorial invalidity. Measures of model fit showed only small misfit because nuisance parameters, magnitude of factor loadings and a balanced/imbalanced number of indicators per factor, also influenced the degree of misfit. Drawing from our results, we discuss challenges in the assessment of factorial validity.

This study aimed to obtain empirical evidence on the influence of fundamental factors, systematic risk and macroeconomics on the returns Islamic stock of companies incorporated in the Jakarta Islamic Index in 2010-2014. The variables used were the fundamental factors that are proxied by Earning Per Share (EPS), Return on Equity (ROE), Debt to Equity Ratio (DER); Systematic risk is proxied by Beta Shares; macroeconomic factors is proxied by the inflation rate and the exchange rate. The samples of this study are the enterprises incorporated in Jakarta Islamic Index (JII) at the Indonesian Stock Exchange. The sampling method was using purposive sampling. There were 12 samples of Islamic stocks that meet the criteria to be used as samples. The analysis model used is multiple linear regression techniques and the type of data used is secondary data. The study found that all variables, which are Earning Per Share (EPS), Return on Equity (ROE), Debt to Equity Ratio (DER), Beta stock, inflation and the exchange rate do not significantly affect the return of sharia stock either simultaneously or partially.

describe the implementation of an integrated quality management component consisting of the quality of services provided by the school, human resources in teaching, the school environment, and learning process  in SLB YPAC Pangkalpinang.               The method used in this study, namely by using a naturalistic qualitative approach. Data collection is done through observation, interviews, and documentation. The subjects of this study include the principal, teachers, employees, and students. The validity of the data is done by triangulation, and deeper observation. Analysis of the data used is the interactive analysis model of Miles and Huberman through data collection, data reduction, data presentation, and conclusion drawing.              The results showed that: (a) the quality of services to students in SLB YPAC Pangkalpinang had met good service standards. This can be seen from the services in the form of facilities and infrastructure which are quite complete in schools; (b) the quality of human resources in the education process shows good teacher resources. This can be seen from the teacher data which shows that the teaching staff at SLB YPAC Pangkalpinang 95% of educators with S1 qualifications in the field of education; (c) the quality of the environment in SLB YPAC Pangkalpinang is already good. This can be seen from the very strategic location of the school because the location of the school is in the middle of the city so that it is easily accessible by the community; (d) the quality of the learning process carried out by teachers at Pangkal Pinang YPAC SLB is good. This can be seen from the realization of the form of activities through learning planning by preparing lesson plans for each subject, then implementing learning, which includes strategies and methods used by teachers in delivering learning material, and evaluation of learning.

Needs Analysis in the context of language-learning-teaching is an important process to design a certain course and syllabus. It helps course designers to set objectives, choose content, method of instruction, appropriate teaching aids, and classroom activities for different courses. This paper reports the perceptions of the researchers on the English language learning needs of the English undergraduate students of Shaheed Benazir Bhutto University Sheringal, Pakistan. The data is based on the researchers’ personal experience and first-hand observation of the population as the researchers have been teaching in the target context for about a decade. Furthermore, the researchers have always been in discussion with their students and colleagues about the target students’ English learning needs, preferred learning styles, motivation in learning English, interest, strengths/weaknesses, and attitude toward English learning in the target setting. Learners’ assignments, exam answer sheets, and presentations have also been used is a source of data collection. A needs analysis model proposed by Hutchinson and Waters (1987) has been applied in order to analyze the data. The results show that the students lack well grammatical sentences, have poor spellings, capitalization problems, limited vocabulary, unaware of collocations, poor/slow reading comprehension, and lack of effective presentation skills. Furthermore, most of the students have a lack of involvement in classroom activities and feel shy about speaking the English language. It was reported that the provision of authentic material, interesting activities, suitable audio-visual aids, relevant texts, language labs, and other logistic arrangements can better help them in learning the English language. The findings demonstrate that the students wished to have a learner-centered-course that helps them excel in their academic life and learning the English language.

Correct Understanding

This article in principle wants to examine the history of the emergence of the conflict of Islamic revival in Minangkabau starting from the Paderi Movement to the Youth in Minangkabau. Especially in the initial period, namely the Padri movement, there was a tragedy of violence (radicalism) that accompanied it. This study becomes important, because after all the reformation of Islam began to be realized by reforming human life in the world. Both in terms of thought with the effort to restore the correct understanding of religion as it should, from the side of the practice of religion, namely by reforming deviant practices and adapted to the instructions of the religious texts (al-Qur'an and sunnah), and also from the side of strengthening power religion. In this case the research will be directed to the efforts of renewal by the Padri to the Youth towards the Islamic community in Minangkabau. To discuss this problem used historical research methods. Through this method, it is tested and analyzed critically the records and relics of the past. In analyzing the data in this research basically used approach or interactive analysis model by Miles and Huberman. In this analysis model, the three components of the analysis are data reduction, data presentation, and conclusion drawing or verification, the activity is carried out in an interactive form with the process of collecting data as a process that continues, repeats, and continues to form acycle.
