Following the educational reform trend around the world, Oman and Taiwan emphasize on teacher quality to improve student learning. This study investigated the relationship between teacher quality and eighth graders mathematics achievement in Oman and Taiwan by utilizing TIMSS 2011 data. The research question examined to what extent teacher quality as defined by the measurable variables (teacher qualification, teaching practices and professional development) impacts student achievement in Oman and Taiwan. The study employed Ordinary Least Square (OLS) statistical analysis to examine the relationship between teacher quality and eighth-grade student math performance in both countries. The results show that teacher quality indicators in Oman and Taiwan have a positive impact on eighth graders mathematics achievement. However, teacher quality variables that influence student achievement in both countries vary depending on the education context, student characteristics and school factors. The study findings support policy intervention aimed at improving teacher quality and recommends providing more opportunities for participation in content-focused and pedagogical-focused professional development.

" In seeking to develop a strong national workforce to support its long-term economic development, the United Arab Emirates (UAE) has placed an exceptional amount of emphasis on improving the quality of education. Nevertheless, public school students continue to perform poorly compared to their counterparts in international assessments such as the Program on International Student Achievement (PISA), Progress in International Reading Literacy Study (PIRLS), and Trends in International Mathematics and Science Study (TIMSS) (International Association for the Evaluation of Education Achievement [IEA], 2011; Mullis, Martin, Foy, & Drucker, 2012; Organisation for Economic Co-operation and Development [OECD], 2013; Ridge, 2014). In addition, a segregated learning environment in which male, non-Emirati teachers teach boys and female, Emirati teachers teach girls has allowed for girls to outperform their male peers in every subject on both national and international school assessments (IEA, 2011; Ministry of Higher Education and Scientific Research [MOHESR], 2015). One possible factor that could account for these gendered differences in student achievement is widely believed to be teacher quality. However, existing research has found only weak or inconsistent relationships between traditional, observable measures of teacher quality, such as teacher content knowledge; years of experience; education levels, with student achievement (Darling-Hammond, 2000; Muñoz & Chang, 2007). To date there has been very little existing research that examines the impact of unobservable teacher characteristics such as teacher behavior on student achievement. This working paper therefore presents the results of research that extends the existing literature on the relationship between teacher characteristics and student achievement by exploring the impact of unobservable teacher characteristics (in this case behavioral traits) on student achievement in English. Using lab-in-the-field experiments, 118 teachers in the emirate of Ras Al Khaimah participated in risk, patience, and altruism tasks. Results suggested that female teachers were more risk- averse (less-polarized distributions), patient, and altruistic than male teachers. Moreover, we found that students of risk-averse teachers had higher scores on average than their risk-seeking counterparts. Finally, risk-seeking and impatience had a more detrimental impact on student achievement for the students of male teachers (boys) than for the students of female teachers (girls). With these findings in mind, we see a need for a larger study to further assess the impact of the nationality segregated nature of the UAE’s teaching sector on teacher behavior, and on the relationship between teacher behaviors and students’ performance. We also recommend a review of expatriate teacher employment terms and of national teacher incentives to equalize the working conditions of teachers in boys’ and girls’ schools and to attract and retain Emiratis (both males and females) to enter the teaching profession in order to improve overall student achievement." دوماً ما تعتبر جودة المعلمين أحد العوامل المحتملة ذو التأثير على أداء الطلبة و بالرغم من ذلك، قامت البحوث الموجودة بالتركيز على عوامل سهلة القياس مثل معرفة المعلم في المادة، و سنوات الخبرة، و مستوى التعليم. تقوم ورقة العمل هذه بتقديم نتائج بحثية تعمقت أكثر من سابقاتها في العلاقة بين شخصية المعلمين و أداء الطلبة عن طريق النظر في تأثير العوامل التي لا يمكن قياسها (سلوك المعلم في هذه الحالة). و قد تم إستخدام أسلوب التجارب المختبرية في الميدان حيث شارك ١١٨ معلم في إمارة رأس الخيمة في مهام المجازفة، و الصبر، و الإيثار، و نتائج من تجارببهم التي تم تعيينها لأداء طلابهم

This study explores the effects of interactions among key stakeholders, i.e., auditors, underwriters, and firm owners on IPOs’ first-day returns in selected OECD nations. It also examines the alteration effects of legal origin (Common law and Civil law) on the relationship between the interacted key stakeholders and IPOs’ first-day returns. A total of four thousand one hundred and sixty-four IPOs from twenty-eight OECD nations are included in this study. Since it is cross-sectional data, a two-stage least square regression is applied. The empirical outcomes indicate that, in general, the interacted reputable underwriters and auditors have a positive impact on IPOs’ first-day return. The relationship is modified between common law and civil law nations, whereby in civil law nations, no significance is demonstrated except for the interaction between the reputable auditors and underwriters. In the common law nation, interactions between reputable auditors and ownership retention have an impact on IPOs’ first-day return. The research findings provide outlooks into an IPO framework for issuers, investors, and regulators. Issuers may want to weigh carefully the costs and benefits of hiring credible auditors and underwriters when going public as they act as signaling agents. As for the investors, they should take into consideration the involvement of reputable underwriters and auditors and the degree to which the IPO firms retain ownership, as the interactive effects give clear signals on firm valuation and IPOs’ first-day returns. Regulators may find the findings informative concerning the creation of a more organized regulatory and financial system that could lead to a deeper and more open financial market.

Purpose The abolishment of the wine tax in Hong Kong has led to increased wine consumption and increased demand for wine-related professionals, such as sommeliers. Yet the importance of sommeliers’ value-adding performance in the context of upscale Chinese restaurants has not been examined. To address this gap, the SERVQUAL framework is adopted to examine the influence of sommeliers’ service quality (SQ) on customer satisfaction (CS) and loyalty in the context of upscale Chinese restaurants in Hong Kong. Design/methodology/approach The survey method is used to collect data from 302 units of the population of interest, partial least square-structural equation modelling (PLS-SEM) is used to test the links between constructs. Findings Four of the seven dimensions of sommeliers’ service quality, namely, empathy, tangibles, credibility and assurance, have a significant positive impact on customer satisfaction and customer loyalty, whereas the impact of perceived value and responsiveness on customer satisfaction and customer loyalty is positive but only marginally significant. Reliability has a weak and non-significant impact on customer satisfaction and customer loyalty. Research limitations/implications Examining a small number of upscale Chinese restaurants in Hong Kong limits generalisation of the findings to other contexts. Replication of the research in different contexts will enhance generalizability. In terms of implications, the discussion highlights the importance of sommeliers’ service performance on customers’ SQ perceptions SQ, CS and loyalty, all of which are important variables for restaurateurs. Originality/value To the best of the authors’ knowledge, this is the first study of the influence of the quality of sommelier’s SQ on CS and loyalty in upscale Chinese restaurants in Hong Kong. Given the lack of attention to this service role in the literature, the study contributes theory from which further understanding can develop.

With the rapid development of information technology, information security has been gaining attention. The International Organization for Standardization (ISO) has issued international standards and technical reports related to information security, which are gradually being adopted by enterprises. This study analyzes the relationship between information security certification (ISO 27001) and corporate financial performance using data from Chinese publicly listed companies. The study focusses on the impact of corporate decisions such as whether to obtain certification, how long to hold certification, and whether to publicize information regarding certification. The results show that there is a positive correlation between ISO 27001 and financial performance. Moreover, the positive impact of ISO 27001 on financial performance gradually increases with time. In addition, choosing not to publicize ISO 27001 certification can negatively affect enterprise performance.

Background While many studies show that greater economic inequality widens the achievement gap between rich and poor students, recent studies indicate that countries with greater economic inequality have lower overall student achievement. Purpose This study explores whether family inequalities (family income) or school inequalities (educational materials or teachers with university degrees) reduce overall student achievement through micro-economic mechanisms, such as fewer educational resources (via rent-seeking) or inefficient resource allocation (via diminishing marginal returns). Population/Participants/Subjects The Organisation for Economic Cooperation and Development's Programme for International Student Assessment (OECD-PISA) selected 475,760 representative fifteen-year-olds and their principals from 18,094 schools in 65 countries. Research Design In this secondary analysis, we tested whether family or school inequalities were related to students’ mathematics test scores, and whether fewer educational resources or inefficient resources allocation mediated these relationships. Data Collection and Analysis Each student received a mathematics test. The students and their principals also received a questionnaire. World Bank economic data on each countries were merged with the OECD-PISA data. To analyze this data, we used item response models, Warm indices and multilevel analyses. Findings/Results In countries with greater family inequality (GDP Gini) or school inequalities (of educational materials or teacher quality), students had lower mathematics achievement. The results were similar in all student subsamples (high vs. low SES; high vs. low achievement). As the mediation results for each inequality differed, they suggest that these inequalities operate through different mechanisms. Family inequality and school inequality of teacher quality are linked to fewer teachers with post-secondary education and lower mathematics achievement. Meanwhile, school inequality of educational resources is linked to diminishing marginal returns and lower mathematics achievement. Conclusions/Recommendations Family inequality and school inequalities (educational materials, teacher quality) are distinct inequalities that are all linked to lower mathematics achievement, but not substantially correlated with one another. Thus, each inequality can be addressed separately. As none of the subgroups of students (not even the richest ones) benefit from any of the inequalities, disseminating the results widely can help more laypeople (especially the richest ones) recognize their mutual benefit in reducing these inequalities –or reduce their inclination to support policies that exacerbate these inequalities. As reducing family inequality can be extremely costly and politically controversial, a strategic intervention at the inequality mechanism level (e.g., increasing teacher quality in schools with few high quality teachers) might be improve mathematics achievement more effectively.
