The Relationship

Curriculum design assumes that successful completion of prerequisite courses will have a positive impact on student performance in courses that require the prerequisite. We recently had the opportunity to test this assumption concerning the relationship between completion of the organic chemistry prerequisite and performance in introductory biochemistry. We found no statistically significant differences between average biochemistry grades or grade distribution among students with or without the organic chemistry prerequisite. However, students who had not completed the organic chemistry prerequisite before biochemistry were more likely to withdraw from the course than those who had completed the prerequisite. In contrast to the lack of correlation between performance in biochemistry and completion of organic chemistry, we observed a strong, highly significant positive relationship between cumulative GPA and the biochemistry grade. Our data suggest that excluding students without organic chemistry would have less positive impact on student success in biochemistry than would providing additional support for all students who enroll in biochemistry with a cumulative GPA below 2.5.

Alliance Portfolios

Given the increasing interest in alliance portfolios, alliance portfolio diversity (APD) has been the focus of many recent studies. Yet, the performance consequences of APD—or of diversity in general—are neither theoretically clear nor empirically consistent. With meta-analytic analyses, we assess extant research on the APD–performance link. Across studies, APD has a positive impact on performance, although the level of analysis and how performance is measured influence the relationship. Going beyond conventional quantitative synthesis, however, we also systematically uncover patterns in how theoretical orientation and the operationalization of diversity moderate the APD–performance relationship. Our study serves as an invitation for future APD studies to employ more sophisticated theoretical and operationalization approaches as they expand our knowledge of diversity in alliance portfolios.

The Relationship

Purpose The non-existence of the corporate governance (CG) concept for practices by non-financial medium-sized firms (MSFs) in Nigeria informed. This study aims to determine whether CG practices influence firms’ performance and whether sustainability initiative (SI) mediates the relationship between CG and MSFs’ performance in Nigeria. Design/methodology/approach A total of 300 firms were selected on convenience sampling basis from South Western Nigeria using a structured questionnaire. The authors used Statistical Package for Social Sciences for exploratory data analysis and hypotheses were tested using covariance-based structural equation modelling. Findings The results show that CG has a significant positive effect on performance [financial performance (FNP) and non-financial performance (NFP)] and SI. SI has a mixed impact on performance, e.g. a significant positive impact on NFP but insignificant negative impact on FNP. Similarly, SI has a combined mediating effect in the relationship between CG and performance, e.g. fully mediates CG → NFP and does not mediate CG → FNP. Firms are to invest in social and environmental initiatives substantially. CG codes will complement the International Financial Reporting Standards for MSFs. Research limitations/implications This study supports the assumptions of theories (institutional, stakeholder and agency) as the basis for the usage of multiple approaches to determine the outcome of hypotheses, especially in developing climes. Practical implications The study contributes to CG and performance literature by examining the mediating effects of SI. The paper also shows the necessity to emphasise NFP aspect. Policymakers should evolve CG codes to encourage stakeholders to believe more in the corporate existence of MSFs for strengthening capital-base and quality personnel engagement. Originality/value To the best of the authors’ knowledge, this is one of the first empirical attempts showing the evidence on the relationship between CG and NFP in Nigeria.

PurposeWith the rise of service economy, many companies are attempting to gain a competitive advantage through service innovation. However, the existing research has not drawn consistent conclusions about the relationship between service innovation and firm performance. Hence, the purpose of this paper is to provide a quantitative review on the service innovation-performance relationship based on research findings reported in the extant literature.Design/methodology/approachStudies from 46 peer-reviewed articles were sampled and analyzed. A meta-analytic approach was adopted to conduct a quantitative review on the relationship between service innovation and firm performance, and the effects of any potential moderators were further explored.FindingsThe results found that service innovation has a significant positive impact on firm performance. Additionally, the relationship between service innovation and firm performance is influenced by measurement moderators (economic region and performance measurement), and contextual moderators (firm type, innovation type, customer factors and attitudes toward risk).Originality/valueThe meta-analysis has been used to explore the relationship between service innovation and firm performance, and the findings have contributed to the literature on service innovation, as well as providing future research directions.

In a world filled with big data, mathematical models, and statistics, the development of strong quantitative skills is becoming increasingly critical for modern biologists. Teachers in this field must understand how students acquire quantitative skills and explore barriers experienced by students when developing these skills. In this study, we examine the interrelationships among gender, grit, and math confidence for student performance on a pre–post quantitative skills assessment and overall performance in an undergraduate biology course. Here, we show that females significantly underperformed relative to males on a quantitative skills assessment at the start of term. However, females showed significantly higher gains over the semester, such that the gender gap in performance was nearly eliminated by the end of the semester. Math confidence plays an important role in the performance on both the pre and post quantitative skills assessments and overall performance in the course. The effect of grit on student performance, however, is mediated by a student’s math confidence; as math confidence increases, the positive effect of grit decreases. Consequently, the positive impact of a student’s grittiness is observed most strongly for those students with low math confidence. We also found grit to be positively associated with the midterm score and the final grade in the course. Given the relationships established in this study among gender, grit, and math confidence, we provide “instructor actions” from the literature that can be applied in the classroom to promote the development of quantitative skills in light of our findings.

The Relationship

Purpose – The purpose of this paper is to investigate the relationship between intellectual capital (IC), categorized in terms of four sub-constructs – namely, human capital (HC), relational capital (RC), innovation capital (InnC) and process capital (PrC) – and business performance in the agribusiness industry. Design/methodology/approach – Based on a sample of international agribusiness companies observed over a five-year period, this paper uses correlation and multiple regression analysis to test for the existence of a positive relationship between each IC component and conventional business performance metrics. Findings – The empirical results support the hypotheses that RC and PrC have a positive impact on corporate performance. Counter to the expectations, InnC by itself is negatively associated with performance. Results also failed to confirm the hypothesis that HC directly and positively affects performance. However HC positively moderates the relation between InnC and performance, which suggests that firms that heavily invest in HC are better placed to gain returns from their research and development (R & D) investments. Originality/value – This study expands the existing research on the link between IC and performance by adding fresh evidence from a highly knowledge-intensive sector which has been under-researched thus far. It may also contribute to the specific literature on R & D and performance as it uncovers that the value-generating effect associated with R & D investments is contingent on the levels of HC.

The Relationship

We assess the relationship between bank governance practice (GCG), efficiency, capital and risk on value creation in a sample of Indonesia commercial banks using the balance panel methodology. Our results suggest that GCG has a positive impact on value creation and performance. We also find that higher interest margin eventually becomes more profitable, better capitalized and that higher capital levels tend to have a neutral or negative effect on value creation. Efficiency levels are positive to value creation. These results are generally confirmed by a series of robustness tests. The findings convey potentially important implications for bank prudential supervision and underline the importance of attaining better governance to support sustainability and financial stability objectives.

The Relationship

This paper aims at providing an empirical evidence concerning the relationship between the ownership structure, capital structure and financial performance of the shareholding companies listed in Amman Stock Exchange (ASE). To measure the ownership structure, the researcher used four variables including foreign, institutional, managerial and concentrated ownership. The capital structure is measured by using the leverage, and the performance is measured by using the return on assets (ROA). To achieve the objectives of the study, a sample of 86 firms from the industrial and service companies listed in ASE during the period 2010 and 2014 is used. The results of the study showed that the relationship between ownership structure in general, and performance is positive and statistically significant, however, the results showed that the various types of ownership structure have different types of relationships with performance. More specifically, there is a negative impact of institutional and foreign ownerships on the performance and positive impact of concentrated and managerial ownerships. The results also revealed that there is a positive impact of the financial leverage on the relationship between ownership structure and firm performance. The findings of the study provide implications to the regulators, investors and managers in Jordan to take into consideration the environment-specific factors when developing corporate regulations and encourage concentrated and managerial ownership because they have positive impact on performance.

The Relationship

This study is taken to describe the relationship between the levels of debt, dividend policy and the performance of firms listed in Vietnamese stock market. The dividend policy is proxied by the dividend yield while firm’s performance is measured by ROE, ROA, and P/E. The total number of observations is 552, collecting from 92 listed companies on Hochiminh Stock Exchange during 2012 and 2019. The analysis results from generalized least squares (GLS) models report that the choice of firm’s performance proxy affects the relationship between firm’s performance and leverage as well as dividend policy. While leverage has positive impact on ROE and ROA, it has negative impact on P/E. In contrast, dividend yield ratio is negatively correlated with ROA and P/E but positively correlated with ROE. However, the impact of debt levels on firm’s performance is independent with the choice of leverage proxy. The findings of this research are expected to provide better understanding about the connection between debt, dividend and performance of the firm that can support the managers to make relevant decisions.

Initial Results

The goal of this paper is to utilize available big and open data sets to create content for a board and a digital game and implement an educational environment to improve students’ familiarity with concepts and relations in the data and, in the process, academic performance and engagement. To this end, we used Wikipedia data to generate content for a Monopoly clone called Geopoly and designed a game-based learning experiment. Our research examines whether this game had any impact on the students’ performance, which is related to identifying implied ranking and grouping mechanisms in the game, whether performance is correlated with interest and whether performance differs across genders. Student performance and knowledge about the relationships contained in the data improved significantly after playing the game, while the positive correlation between student interest and performance illustrated the relationship between them. This was also verified by a digital version of the game, evaluated by the students during the COVID-19 pandemic; initial results revealed that students found the game more attractive and rewarding than a traditional geography lesson.
