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.

To explore the impact mechanism of principals’ transformational leadership on students’ modernity, this study adopted the structural equation model to test the multiple mediating effects of school climate, teacher quality, and effective teaching on the relationship between principals’ transformational leadership and students’ modernity. Results showed that there was a positive correlation between principals’ transformational leadership and students’ modernity; school climate, teacher quality, and effective teaching fully mediated the relationship between principals’ transformational leadership and students’ modernity, totally accounting for 64.37% of all the indirect effects; the mediating effects of school climate, teacher quality, and effective teaching, respectively, accounted for 30.20%, 52.29%, and 17.51%. According to these results, principal should adopt the approach of transformational leadership, promote the constructing of a fair, inclusive and innovative school climate, emphasize the improvement of teachers’ social, emotional, and innovative qualities, and encourage teachers to reflect their teaching and conduct rational practices to improve students’ modernity.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.

The Impact

BACKGROUND The elderly are particularly exposed to adverse events from medication. Among the various strategies to reduce polypharmacy, educational approaches have shown promising results. OBJECTIVE We aimed to evaluate the impact of the implementation of a good medical practice booklet on polypharmacy in nursing homes. METHODS We identified nursing homes belonging to a geriatric care provider that had launched a policy of proper medication use using a good medical practice booklet delivered to prescribers and pharmacists. Data were derived from electronic pill dispensers. The effect of the intervention on polypharmacy was assessed with multilevel regression models, with a control group to account for natural trends over time. The main outcomes were the average daily number of times when medication was administered and the number of drugs with different presentation identifier codes per resident per month. RESULTS 96,216 residents from 519 nursing homes were included between 1 January 2011 and 31 December 2014. The intervention group and the control group both decreased their average daily use of medication (-0.05 and -0.06). The good medical practice booklet did not have a statistically significant effect (exponentiated difference-in-differences coefficient 1.00, 95% confidence interval 0.99-1.02, P=.45). CONCLUSIONS Although the good medical practice booklet itself did not seem effective in decreasing medication use, our data show the effectiveness of a higher-level policy to decrease polypharmacy.

New Evidence

Researchers disagree about the impact of board independence on firm value. The disagreement generally stems from the endogenous nature of board appointments. I add new evidence to this discussion by using a sample of closed-end funds to document the value-enhancing effects of independent boards. Using cross-sectional, difference-in-differences, and instrumental variables techniques, I address these endogeneity concerns and find consistent evidence that board independence is associated with higher firm value.

Abstract This paper evaluates the effect on crime of creating a fundamental modern-day institution: centralized professional police forces tasked with preventing crime. We study the 1829 formation of the London Metropolitan Police – the first professional force worldwide. Using newly digitized and geocoded crime and police data together with difference-in-differences and pre-post designs, we find evidence of a significant reduction in violent crimes (despite the possibility of off-setting increases in clearance and reporting rates). In contrast, a reduction in property crime is not visible

Over Time

We empirically test whether B Corp certification affects the short- and medium-term growth rates of sustainable enterprises. These businesses are growing in popularity and prevalence but, due to their hybrid nature, often suffer from external credibility issues and competing internal logics. Because of the rigorous and time-involving audit procedure, B Corp certification potentially sends a credible signal about the sustainable nature of the enterprise to its stakeholders. In addition, the B Corp label could help to straighten out internal tensions and align the company towards its dual purpose. Hence, B Corp certification could contribute to company success. We observe 129 firms that were certified between 2013 and 2018 over a period between six years prior and five years post-certification. Using propensity score matching, we identify 129 non-certified matching companies. On this sample, we conduct a difference-in-differences panel regression analysis to investigate the effect of certification. Our dataset allows us to study how the effects of B Corp certification evolve over time, which was previously untested. Our study documents a positive effect of B Corp certification on turnover growth and also that this effect increases with the time since certification, implying that certification requires some time for its full effect to become apparent.
