The Most Common Punctuation Errors Made by the English and the TEFL Majors at An-Najah National University

Abstract: The aim of this study is to investigate the most common punctuation mistakes which the English and the TEFL majors at An-Najah National University make in their writing To this end, the researcher administered a test to a stratified random sample of 100 students from An-Najah University: 45 males and 55 females from the TEFL Department in the Faculty of Education and the English Department in the Faculty of Arts The results revealed that the most common errors among the English and the TEFL majors at An-Najah University were: the overuse of comma at the expense of the period, the incorrect use of the capital letter, the wrong use of the quotation marks and the misuse of semicolon respectively Furthermore, the results indicated that there were no significant differences in the number of punctuation errors due to gender and department; however, the results revealed that there were significant differences in the number of punctuation errors among the participants due to academic level In the light of the study findings, the researcher recommended that all the teaching staff should overstress the importance of all the punctuation marks in the written and the oral communication courses

Formulation and bioequivalence of two valsartan tablets after a single oral administration

Abstract: The aim of this study is to assess the quality of Valzan® tablet (160 mg, valsartan immediate release test formulation) by comparing its pharmacokinetic parameters with Diovan® tablet (160 mg, valsartan reference formulation) Valzan® tablets were prepared according to a dry granulation method (roll compaction) To assess the bioequivalence of Valzan® tablets a randomized, two-way, crossover, bioequivalence study was performed in 24 healthy male volunteers The selected volunteers were divided into two groups of 12 subjects One group was treated with the reference formulation (Diovan®) and the other one with the generic Valzan®, with a cross-over after the drug washout period of 14 days Blood samples were collected at fixed time intervals and valsartan concentrations were determined by a validated HPLC assay method The pharmacokinetic parameters AUC0–48, AUC0–∞, Cmax, Tmax, Ke and T1/2 were determined for both the tablets and were compared statistically to evaluate the bioequivalence between the two brands of valsartan, using the statistical model recommended by the FDA The analysis of variance (ANOVA) did not show any significant difference between the two formulations and 90% confidence intervals (CI) fell within the acceptable range for bioequivalence Based on this statistical evaluation it was concluded that the test tablets (Valzan®) is well formulated, since it exhibits pharmacokinetic profile comparable to the reference brand Diovan®

Systems thinking for call centre service design: affective commitment implications in manufacturing enterprises

Abstract: This paper explains the leveraging of affective commitment among call centre front-line employees through the improvement of service operations design in a manufacturing enterprise through systems thinking approach. A case study was carried out using face-to-face interviews, structured questionnaires, and observation methods to collect data at managerial and operative front-line levels. The case study finds a strong relationship between the level of affective commitment among front-line employees and the form of service operations system. The study has many implications for the manufacturing enterprises embracing a call centre to improve productivity and working experience. A higher level of affective commitment is likely to mitigate turnover and absenteeism in these service departments.

Bibliometric analysis on global Catha edulis (khat) research production during the period of 1952–2014

Abstract: Publication of scientific articles related to khat (Catha edulis) in peer-reviewed journals is considered a measure of research productivity. The principal objectives of this study were to quantify the research contribution related to khat at the global level, as well as to determine its relative growth rate, collaborative measures taken, productivity at the institutional level, and the most prolific journals publishing on the topic. On the basis of title words related to khat, publications were identified for all data in Scopus bibliographic database’s history up to December 31, 2014. The research productivity for the top 10 countries was evaluated in relation to the population size and gross domestic product (GDP) in 2013. The criteria were met by 651documents published in 51 countries. The largest number of articles associated with khat was from the UK (15.2 %), followed by Yemen (10.3 %), the USA (9.7 %) and Ethiopia (9.1 %). Ethiopia, Yemen, and Kenya had the highest productivity of publications after standardization by population size and GDP. Furthermore, Yemen achieved the highest number of collaborations, by having researchers from 19 countries. Ethiopia followed, having researchers from 16 countries. This bibliometric study provides a demonstration for the worldwide research activity regarding khat. The number of articles related to khat has increased rapidly over the last 10 years. The present study is a good starting point to evaluate research activity in the field of khat. Although the data shows a promising increase in the research activity, the quantity of khat-related research is still too little compared to the massive use of khat in certain countries.
