Brush border intestinal disaccharidases (maltase, sucrase and lactase) play an important role in carbohydrate assimilation. These enzymes are located on the brush border and may interact with legume seed components such as dietary fiber and polyphenols. The purpose of this paper is to assess the effect of legume dietary fiber on rat disaccharidase in vitro.

Rat intestinal disaccharidases from Sprague‐Dawley rats fed a basal diet for 21 days were partially purified from intestinal scrapings. Enzyme activities were tested in vitro in the absence and presence of total dietary fiber isolated from Phaseolus vulgaris (Varieties Tacarigua and Montalbán) and Vigna unguiculata (Varieties Unare and Tuy) seeds that differ in fiber and polyphenol content. Dietary fiber was purified using the AOAC method.

The specific activities of the intestinal brush‐border disaccharidases from rats fed the basal diet were 3.29 ± 0.06, 3.13 ± 0.62 and 0.18 ± 0.04 umoles of glucose released/mg of protein/min for maltase, sucrase and lactase, respectively. Total dietary fiber from the legume tested inhibited both sucrase and maltase. Fiber from the four seeds tested affected sucrase similarly (average inhibition 35 per cent) whereas the fiber residue from P. vulgaris Montalbán was more effective on maltase (26.7 per cent) than that from P. vulgaris Tacarigua (12.2 per cent). Effect of V. unguiculata fibers on maltase was similar and somewhat in between those from P. vulgaris.

These results suggest that dietary fiber, as well as other factors from beans with anti‐physiological effect, such as condensed tannins and fitic acid possibly associated with the dietary fiber, may impair carbohydrate availability and may contribute to the low glycemic index proper of these foodstuffs.

Lean management is a contemporary management system that firms adopt to boost their performance. Lean management can be integrated with human resources management to develop a new concept of lean human resources management (LHRM). This entails the implementation of several practices. However, the LHRM–performance paradigm remains underexplored in the literature. Hence, this study aims to examine the interrelationships between LHRM practices and the impacts of those practices on firm performance (FP).

Using two equal-sized samples (n = 250 each) of manufacturing firms in Jordan and Germany, this study proposes two structural equation models (i.e. a Jordanian and a German models) depicting the interrelationships between LHRM practices and the impacts of those practices on FP. After testing these models, a comparison between them is conducted, producing findings with theoretical and practical implications.

The main findings of this study indicate that the average implementation of LHRM practices among German manufacturing firms is at a higher level than the average implementation among Jordanian firms. The findings also support the proposed interrelationships between LHRM practices and the impact of those practices on FP for both the Jordanian and German models.

To the best of the authors’ knowledge, this study is among the first to highlight the proposed relationships, both in general and in the context of comparing developed and developing countries. Its findings have important implications that can enable manufacturing managers to benefit from the implementation of LHRM practices to enhance FP in different contexts. These findings provide valuable insights for human resource managers and decision-makers and open several avenues for future research.

This paper aims to investigate the relationship between gender diversity and the Carbon Disclosure Project (CDP) score/index. Specifically, the study describes extant research on theoretical perspectives, and the impact of women on corporate boards (WOBs) on carbon emission issues in the global perspective.

This study uses the carbon disclosure scores of the CDP from 2011 to 2013 (inclusive). A total observation for the three-year periods is 1,175 companies. However, based on data availability for the model, the sample size totals 331 companies in 33 countries with firms in 12 geographical locations. The authors used a model which is estimated using the fixed-effects estimator.

The outcomes of the study reveal that there is a positive relationship between gender diversity (WOB) and carbon disclosure information. In addition to establishing a relationship between CDP score and other control variables, this study also found a relationship with Board size, asset size, energy consumption and Tobin’s Q, which is common in the existing literature.

The limitations of the study mostly revolve around samples and the time period. To further test the generalizability and cross-sectional validity of the outcomes, it is suggested that the proposed framework be tested in more socially responsible firms.

There are increasing pressures for WOBs from diverse stakeholders, such as the European Commission, national governments, politicians, employer lobby groups, shareholders, Fortune and Financial Times Stock Exchange (FTSE) rankings and best places for women to work lists. The study offers insights to policy makers implementing gender quota legislation.

The study has important implications for putting into practice good corporate governance and, in particular, gender diversity. The outcomes of the analyses advocate that companies that included women directors and had a smaller board size may expect to achieve a higher level of carbon emission performance and to voluntarily disclose the level of carbon information assessment requested by the CDP.

Small- and medium-sized enterprises (SMEs) mainly rely on their structure and internal networks to achieve their goals and remain competitive. However, their limited internal capabilities and complex environments can hinder their stability. Thus, this study evaluated the relationships among specific factors toward fostering organizational resilience (OR) in tourism SMEs.

A multi-methodological approach was adopted to address this research study, including (1) social network analysis (SNA) to formulate the conceptual model and (2) construct validation through partial least squares path modeling (PLS-PM).

The six proposed hypotheses were supported. These results suggest that addressing these variables and relationships after considering management style and people development as critical factors can foster OR in tourism SMEs.

The ideas that were developed were constrained to the organizational domain. Although the results apply to the Mexican context, this limitation can be offset by extending the proposal to other emergent regions or organizations. This can also increase the generalization of the results and foster improvements in the approaches applied.

Academics and managers must rethink resilience as the final state generated by multiple factors. This requires reconfiguring inner organizational interactions, providing more autonomy to operative units, reinforcing business intelligence and improving feedback mechanisms.

This research study contrasts previous studies because it proposes that SNA be exploited to avail of the advantages it confers in designing the conceptual model. In this regard, we present new relationships to promote OR and provide new avenues in order to improve the analysis of adaptation processes.

The current era of the fourth industrial revolution has attracted significant research on the use of digital technologies in improving construction project delivery. However, less emphasis has been placed on how these digital tools will influence the management of the construction workforce. To this end, using a review of existing works, this chapter explores the fourth industrial revolution and its associated technologies that can positively impact the management of the construction workforce when implemented. Also, the possible challenges that might truncate the successful deployment of digital technologies for effective workforce management were explored. The chapter submitted that implementing workforce management-specific digital platforms and other digital technologies designed for project delivery can aid effective workforce management within construction organisations. Technologies such as cloud computing, the Internet of Things, big data analytics, robotics and automation, and artificial intelligence, among others, offer significant benefits to the effective workforce management of construction organisations. However, several challenges, such as resistance to change due to fear of job loss, cost of investment in digital tools, organisational structure and culture, must be carefully considered as they might affect the successful use of digital tools and by extension, impact the success of workforce management in the organisations.

The authors empirically investigate the impact of the existence of a stand-alone risk committee (RC) and its characteristics on the likelihood of stock price crash risk in listed financial firms on the Bursa Malaysia. The authors also test whether the effect of RC on crash risk is attenuating or amplifying by the level of institutional ownership.

The authors use a principal components analysis (PCA) to aggregate and derive a factor score for risk committee characteristics (i.e. independence, qualification, and size) as a proxy for the effectiveness of RC. The study also employs two distinct stock price crash risk measurements to corroborate the findings and partition institutional ownership into dedicated and transient to examine the potential impact of institutional shareholding on RC-stock price crash risk association.

Regression analysis reveals that only RC qualification has a significant negative impact on stock price crash risk. However, when RC characteristics are aggregated into one composite factor, the authors find that firms with effective RCs exhibit lower risk of stock price crash. The authors also find that firms with high level of institutional shareholdings and effective RCs are less likely to experience crash risk likelihood. The additional analyses indicate that the complementary moderating effect of institutional ownership on RC-crash risk nexus is likely to be driven by dedicated institutional ownership. The results are robust across two measures of stock price crash risk and regression specifications for a longer run window.

The study, to the best of the researchers' knowledge, is the first to provide evidence in an emerging market financial sector companies' perspective suggesting that effective RCs are individually and aggregately associated with lower stock price crash risk, which is further strengthened by dedicated institutional investors. These findings are unique and contribute to a small but growing body of literature documenting the need for effective RCs and specific institutional investors and their consequences of improvements in stock price crash risk environment. Results of our research in this area provide important insights to financial and capital market participants, investors, regulators, and policymakers in Malaysia.

The purpose of this paper is to analyse the adaptive market efficiency in the price–volume (P–V) relationship of the stocks listed in the Mexican Stock Exchange. The period under study goes from 1982 to 2015. In order to detect causality and, thus, determine adaptive efficiency in the market, one linear and two non-linear tests are applied. There are few papers in the literature that study the P–V relationship in Latin American markets; as such, this paper may be of interest and importance to financial academics and practitioners alike.

The Diks and Panchenko (DP) non-parametric Granger causality and the Brooks and Hinich (BH) cross-bicorrelation tests are applied.

Derived from the DP test, the findings show that there exists bi-directional non-linear Granger causality in 25.71 per cent of the firms studied, compared to 8 per cent when applying the linear Granger causality test. Therefore, there is evidence of weak-form efficiency in the market. From the BH test, evidence is shown of the adaptive market efficiency, since 71.42 per cent of firms exhibited some form of non-linear dependence in certain periods of time. With these results, the information process should be better studied for a greater comprehension of regulatory policies in the market and better decision-making tools for the investors.

This paper complements studies on the P–V relationship and efficiency in a Latin American market.

Este documento analiza la eficiencia adaptativa del mercado para la relación precio-volumen de las empresas que cotizan en la Bolsa Mexicana de Valores. El periodo bajo estudio es de 1982 a 2015. Para detectar causalidad y determinar la eficiencia adaptativa del mercado, se aplicó una prueba lineal y dos no-lineales. Existen pocos documentos en la literatura que estudien la relación precio-volumen en mercados latinoamericanos. Como tal, este documento puede ser de interés e importancia tanto para académicos como para profesionales de las finanzas.

Se aplicó la prueba de causalidad no-paramétrica de Diks y Panchenko y la prueba de bicorrelación cruzada de Brooks y Hinich.

Derivado de la prueba DP, los hallazgos muestran que existe causalidad no-lineal bidireccional en 25.71% de las empresas bajo estudio, comparado a un 8% cuando se aplica la prueba de causalidad lineal de Granger. Por lo tanto, existe evidencia de eficiencia en forma débil del mercado. De la pruba BH, se muestra evidencia de eficiencia adaptativa del mercado, dado que el 71.42% de las empresas exhibieron alguna forma de dependencia no-lineal en ciertos periodos de tiempo. Con estos resultados, el proceso de información debe ser mejor estudiado para una mayor comprensión de las políticas regulatorias del mercado y mejores herramientas para la toma de decisiones por los inversionistas.

Este documento complementa los estudios sobre la relación precio-volumen y la eficiencia en un mercado latinoamericano.

Corporate Social Responsibility (CSR) Implementation and Disclosure in the Banking Sector: the case of banks with Islamic identity in Syria. This study aims to explore Corporate Social Responsibility Disclosure (CSRD) in Syrian banks which have an Islamic identity, investigating their motivations when implementing and disclosing CSR and the challenges banks have faced. This study employed content analysis to extract knowledge from 33 annual reports published by three banks which have Islamic identity in Syria over the period 2008–2020. Semi-structured interviews were then conducted with five participants who are aware of CSRD policy in the banks in the sample, in order to gain a fuller understanding of their motivations in relation to CSR and any challenges they faced. This article draws on the overlap between Stakeholder and Legitimacy theories in order to explain the motivations of the banks in question. The study found that banks which have an Islamic identity increased their levels of CSR implementation during the conflict crisis but were not publishing details on these activities because of a concern regarding the Islamic modesty around charitable actions and to avoid upsetting the sensibility of beneficiaries. Interviewees commented that in the time of conflict crisis, many Syrians needed relief and support. Because of this, banks in our research sample decided to take responsibility to lessen the negative impact of the conflict crisis on the Syrian community. In addition, the analysis revealed that banks engaged with Environment and Human Right issues after 2013 because they wanted to fulfil the requirements of their national partners.

This study aims to investigate the determinants of the extent and quality of corporate social responsibility disclosure (CSRD) in Jordan. The study examines a number of factors that influence the extent and quality of CSR disclosure, such as corporate characteristics, corporate governance and ownership structure.

A quantitative approach and a content analysis technique is used to measure the extent and quality of CSRD from annual reports. The sample is drawn from the annual reports of 118 Jordanian companies between 2010 and 2015. A CSRD index is constructed, which includes the disclosures of the following categories: environmental, human resources, product and consumers, and community involvement. This is the first study that presents a new measurement for CSR disclosure quality by using images and charts in a seven-point scale measurement.

The result reveals that the extent of CSRD is higher than quality in Jordan. Regarding the determinants of CSR disclosures, the following factors were found to have a significant relationship with both the extent and quality of CSRD: board size, non-executive directors, age of firm, foreign members on the board, number of boards meetings, the presence of audit committees, big 4, government ownership, size of firm and industry type. Non-executive directors was found to have a significant correlation with the extent of CSRD.

The current study has some limitations; first, the study findings are limited to the Jordanian environment. Second, the study adopted a purely quantitative method, and future research could include interviews and questionnaires to gather data from financial managers and chief executive officers (CEOs). Third, the potential influences on the level and quality of CSR are not limited to the variables tested in this study. Future research can be done on new determinants, such as CEO interlocking and profitability. Finally, the sample included companies from two main sectors – the services and industrial sectors; thus, this limited the results to these two main sectors.

Practitioners, as firms, should develop new strategies and ensure that CSR is included in their reports. Thus, companies can achieve legitimacy for their products and activities. Policymakers must consider introducing new laws that mandate CSRDs since it has many advantages for companies and society. In addition, this research suggests amending the law to require companies to have 33% of their directors be non-executives since this will remove the negative effect on CSR disclosure. Investors must pay attention to the social activities of the companies they invest in, as CSR could have a positive effect on their market value.

The study has indicated that Jordanian companies became increasingly more involved in CSR activities, as this growth in CSRD is linked with global increases in CSR. Moreover, the study has revealed that the highest category of CSR disclosures is related to products or services and employee information. On the other hand, the lowest category of CSR disclosures is related to community and other disclosures (extent) and environmental disclosures (quality). Furthermore, the results show that the services sector was found to have more disclosures regarding employees and community, whereas the industrial sector was more concerned about environmental and product information.

To the best of the authors’ knowledge, this is the first study that presents a new measurement for CSR disclosure quality by using images and charts in a seven-point scale measurement. This new seven-point scale will be adopted to distinguish between poor and excellent disclosures. In addition, to the best of the authors’ knowledge, this is the first study in Jordan which examines the determinants of the extent and the quality of CSR for three categories, namely, corporate characteristics, corporate governance and ownership structure.
