The objective of the present study is to investigate the relationship between managers’ professionalism and (technical, human, and perceptual) skills in managers of Iran Poly Akril Company. The research is an applied one in terms of objectives, and a descriptive-correlational in terms of method. The population includes all experts working in the company in 2012 as 240 individuals among who 144 participants were selected using the stratified random sampling method proportionate to the population size as the sample size. The data collection instruments were two researcher-made questionnaires of Managers’ skills containing 22 items and with the reliability coefficient as 0.96, and Professionalism containing 28 items and the reliability coefficient as 0.95. Their validity was investigated and confirmed by professors and experts of management. Analyzing data was conducted at the two level of descriptive statistics (frequency, mean, SD, and presentation of tables and charts) and inferential statistics (one sample t-test, correlation coefficient, regression coefficient, ANOVA, and F-test).

Eye Movements During Reading

A Beckman Type RM Dynograph was used to record the eye movements of 26 professional college men, once without spectacle corrections and then with piano lenses on a trial frame, during reading equivalent print at a distance of 33 cm. Amplitudes of the return-sweep velocity on these two trials were used to calculate an equivalent form reliability coefficient. A Pearson r of 0.88 indicates that their reliability is moderately high, meaning that both the desirable as well as the undesirable reading habits are probably deeply rooted by college, and imply that any reading remediation or improvement training should be performed at some much earlier stages to be efficiently effective.

The study aims to explore the degree of awareness of Jordanian education college students to terrorism's definition, type and causes, and the universities' roles in addressing terrorism. A five- scale questionnaire was designed by the author and administrated to 130 students studying at the faculty of education, Al-al Bayt University. The external reliability coefficient for the total questionnaire domains was 0.84, and the internal reliability coefficient (Cronbach Alpha) for the total questionnaire domains was 0.88. This indicates that the questionnaire was reliable and suitable for a sample administration. The results indicated that students were aware of the concept and types of terrorism, but they have a misconception of its main causes. These, however, were relevant from the perspectives of economical and social causes. Students' misconception can be interpreted by students' social alienation, and their refusal based on economic and social circumstances. The author suggested that universities must hold intense rehabilitating programs for the youths. This is in addition to holding international conferences on human security as it could raise students' awareness of terrorism and help them in addressing it eventually.

Reliability Coefficients

McNeish (2018) advocates that researchers abandon coefficient alpha in favor of alternative reliability measures, such as the 1-factor reliability (coefficient omega), a total reliability coefficient based on an exploratory bifactor solution (“Revelle’s omega total”), and the glb (“greatest lower bound”). McNeish supports this argument by demonstrating that these coefficients produce higher sample values in several examples. We express three main disagreements with this article. First, we show that McNeish exaggerates the extent to which alpha is different from omega when unidimensionality holds. Second, we argue that, when unidimensionality is violated, most alternative reliability coefficients are model-based, and it is critical to carefully select the underlying latent variable model rather than relying on software defaults. Third, we point out that higher sample reliability values do not necessarily capture population reliability better: many alternative reliability coefficients are upwardly biased except in very large samples. We conclude with a set of alternative recommendations for researchers.

This research is a study of quantitative descriptive. The purpose of this research is to describe the characteristics of final semester exam items for grade XI in the History subject at SMA Negeri 1 Pangkalpinang using the classical test theory approach. The research of the subject was 138 students of class XI in Social Sciences Major. The result of the research shows that final exam questions in the history subject class XI of SMA Negeri 1 Pangkalpinang are proper to use. This shows that from the validity of the items which there are 39 items of questions (97.5%) which are proven empirically valid with a 0.818 reliability coefficient. Other than that, there are 27 items of questions (67,5%) that can fulfill the criteria for the difficulty level, distinguishing power, and distractor function so it can be used directly to measure the student's ability without correction. While 12 items of questions (30%) need to be fixed and 1 item of question (2,5%) is declared to be invalid so it can't be used to measure the student's ability in History Subject. Permasalahan yang melatarbelakangi penelitian ini adalah pengembangan soal penilaian akhir semester mata pelajaran sejarah yang tidak melalui tahapan analisis butir soal sehingga kualitas butir soal tidak diketahui. Penelitian ini merupakan penelitian deskriptif kuantitatif. Tujuan penelitian ini adalah untuk mendeskripsikan karakteristik butir soal penilaian akhir semester mata pelajaran sejarah kelas XI SMA Negeri 1 Pangkalpinang menggunakan pendekatan teori tes klasik. Subjek penelitian berjumlah 138 peserta didik kelas XI jurusan IPS. Hasil penelitian menunjukkan bahwa soal PAS mata pelajaran sejarah kelas XI SMA Negeri 1 Pangkalpinang telah layak digunakan. Hal ini dibuktikan dari validitas butir soal yang mana terdapat 39 butir soal (97,5%) terbukti valid secara empirik dengan koefisien reliabilitas sebesar 0,818. Selain itu terdapat 27 butir soal (67,5%) yang memenuhi kriteria tingkat kesukaran, daya beda, dan keberfungsian distraktor sehingga dapat digunakan langsung untuk mengukur kemampuan peserta didik tanpa perbaikan. Sedangkan sebanyak 12 butir soal (30%) perlu dilakukan perbaikan dan 1 butir soal (2,5%) dinyatakan gugur sehingga tidak dapat digunakan untuk mengukur kemampuan peserta didik pada mata pelajaran sejarah.
