Abstract

Purpose

This paper aims to evaluate the effect of consumption of a high-fat diet (HFD) rich with total saturated fats on adiposity and serum levels of vascular cell adhesion molecule (sVCAM-1), a biomarker of endothelial inflammation/dysfunction. Another aim is to evaluate whether supplementation of a phytosomal formulation of curcumin would reduce adiposity measures and sVCAM-1 levels in HFD rats.

Design/methodology/approach

The study was conducted on 17 male rats which were allocated to one of three feeding regimen groups: normal diet (ND); HFD, or HFD with dietary phytosomal curcumin (HFD-C). Anthropometric measures were recorded weekly up to 20 weeks of feeding intervention, at the end of which, sVCAM-1 levels were also compared with one-way ANOVA and Tukey post-hoc analysis.

Findings

The HFD group had the greatest values for raw anthropometric data, and there was a group difference in anthropometric measures, however there was no significant difference between HFD and HFD-C for any measure. The gain at 20 weeks from initial values did reveal significant differences in weight and abdominal circumference between HFD and HFD-C groups. There were significant group differences in sVCAM-1 levels, with only HFD-C displaying significant lower levels than HFD group.

Originality/value

This is the first study that shows the capacity of a phytosomal formulation of curcumin in reducing adiposity and sVCAM-1 levels during daily intake of saturated fats above the recommended level. The results are promising in that this formulation can protect against endothelial inflammation/dysfunction, and can be used as complimentary therapy to suppress dyslipidemia/obesity-related cardiovascular complications.

Abstract

Purpose

Family businesses have a dual objective of profit making and providing opportunities for family members. This duality leads to a conflict that may bring poor team work and communication, which is difficult to reconcile. Thus, the study looked into how the performance of family enterprises is affected by family dynamics. Additionally, it examines the relationship's ability to be mediated by effective leadership.

Design/methodology/approach

The study adopted a quantitative, explanatory research approach. The study population was family-owned enterprises in KwaZulu-Natal's South Durban Basin, of which 236 were chosen using a snowball and convenience sampling technique. Data was analysed using various descriptive and inferential statistical techniques, namely, multiple regression and the standard deviation.

Findings

The finding of the study shows that family dynamics significantly influenced business performance both directly and indirectly through effective leadership. Besides, the family firms with larger employee sizes have better effective leadership that positively contributes to the business performance.

Research limitations/implications

The study recommends that family businesses should train their members to ensure leadership effectiveness.

Originality/value

This study is unique in that it was conducted in Black Townships and focusses mainly on businesses owned by families of Indian descent that need to prepare for leadership/ownership. It also contributes to academic literature on family dynamics and will encourage families to recognise the importance of strong leadership in controlling family dynamics to improve business success.

Abstract

Purpose

Family businesses (FBs) are considered an essential type of entrepreneurship that impacts economic growth. However, statistics show that after a period of performance they ultimately fail, and comparatively little is known about the reasons for their failing when compared to the amount of research focusing on keys to success.

Design/methodology/approach

Through the implementation of an case study technique, which is widely used in research to address the complex phenomenon of failure, this paper aims to analyse the antecedents of failure in the case of four Catalan FBs. In doing so, this article develops propositions based on Institutional Economics Theory and Dynamic Capability Theory, with a focus on innovation and product diversification in family firms.

Findings

Using interviews as a means of obtaining a large amount of information, it is observed that problems related to governmental regulations and constantly changing social behaviour can lead to failure for FBs. Additionally, a link between R&D activities and new product development and FB failure is observed. More specifically, this research highlights that a lack of product diversification and innovation can become a hindrance for FB performance when the institutional environment is unstable. It reveals the importance of developing dynamic capabilities that can meet the demands of fast-changing consumer behaviour. From a practical perspective, these findings can be used by governments in developing regulations focused on the dynamic capabilities of FBs, and by managers in order to learn from these experiences and implement appropriate strategies for long-term development and crisis management.

Originality/value

This paper theoretically contributes to both the FB literature, as well as to institutional economics and dynamic capability theories by offering a combined perspective on how FB's dynamic capabilities change based on environmental factors and impact FB failure.

Abstract

Purpose

The primary objective of this paper is to explore the robust determinants influencing the infection rate and case mortality rate of COVID-19 in both developing and developed economies. The analysis is conducted using a dataset encompassing 148 countries.

Design/methodology/approach

To achieve this goal, empirical testing utilizes the Sala-i-Martin version of extreme bounds analysis, a method grounded in the cumulative density function. This approach allows for a comprehensive exploration of potential determinants.

Findings

The analysis results reveal that, to a large extent, distinct factors contribute to the infection and mortality rates in developed and developing countries. Notwithstanding these differences, certain common factors emerge, such as the risk environment, the number of tests conducted per million people and the percentage of the population over 65.

Originality/value

Despite acknowledging the potential limitations inherent in official data, this study concludes that the presented results offer valuable insights. The identified determinants, both unique and common, contribute to understanding the dynamics of COVID-19 in diverse economic settings. The information gleaned from this research holds significance for decision-makers involved in combating the ongoing pandemic.

Abstract

Purpose

The aim of this paper is to examine the effect of structural and demographic board diversity as well as board tenure on family firms' environmental performance, by analyzing the differences between family and non-family businesses and within family firms.

Design/methodology/approach

Tobit regressions are applied to investigate the effect of independent directors, CEO non-duality, board gender diversity and board tenure on environmental performance. The study also controls for other board and firm characteristics, as well as for time, industry and country-fixed effects. In doing so, the authors rely on a sample of non-financial listed firms from France, Germany, Italy, Spain and Portugal over the period 2014–2021.

Findings

The authors find that women on the board positively influence environmental performance and this effect is significant only in family firms, although board tenure negatively moderates the relationship. Board independence significantly affects environmental performance only in non-family firms. A strong presence of family directors has a negative effect on family firms' environmental performance, especially when directors' turnover is low.

Originality/value

This paper examines the unexplored relationship between structural board diversity and environmental performance in family companies. This study provides empirical evidence on the association between gender diversity and family firms' environmental performance focusing for the first time on a European setting. Moreover, this study provides evidence of a different effect of board tenure in family and non-family businesses.

Abstract

Purpose

The purpose of this article is to systematically review existing literature concerning the transmission of entrepreneurial values within the context of family entrepreneurship. Specifically, the study aims to address two primary inquiries: First, which entrepreneurial values transferred across generations have been discerned in family entrepreneurship literature? Second, what mechanisms for the transmission of these values have been identified within family entrepreneurship literature?

Design/methodology/approach

We utilized the Web of Science database to identify relevant articles. We employed a broad set of Boolean search terms related to family, entrepreneurship and values. Ultimately, 77 articles were selected for detailed analysis based on their relevance to the topic.

Findings

Our review identified a diverse array of entrepreneurial values that can be categorized into three themes: family values, family business values and societal entrepreneurial values. Furthermore, mechanisms facilitating the transmission of these values were classified into eight distinct types, i.e. relational embeddedness, vicarious learning, explicit communication, imprinting, educating, parenting styles, community-zeitgeist and genetics. The paper concludes with an agenda for future research on entrepreneurial value transmission in enterprising families.

Practical implications

Understanding how entrepreneurial values are transmitted within family firms can inform practices such as succession planning, leadership development and fostering a culture of entrepreneurship across generations.

Originality/value

This paper contributes to the theoretical development of family entrepreneurship by consolidating and synthesizing existing knowledge on entrepreneurial value transmission. It provides a comprehensive overview that can guide future empirical and conceptual investigations in this field.

Abstract

Purpose

This paper aims to investigate the effect of supplier relationship management (SRM) on the business performance of small-scale grapes processing firms in Dodoma, Tanzania. The paper also examines the moderating role of logistics capabilities in the relationship between SRM and business performance.

Design/methodology/approach

This research uses a cross-sectional survey design. A structured questionnaire was used to collect data from 202 small-scale grape processing firms. The data were analysed through descriptive and structural equation modelling.

Findings

The findings revealed that buyer-supplier relationships, supplier development and supplier selection were positively and significantly related to business performance. Furthermore, knowledge transfer had no relationship with business performance. On the other hand, the findings showed that logistics capabilities significantly moderated the relationship between SRM and business performance.

Research limitations/implications

The study was cross-sectional, conducted only in Tanzania, and focussed entirely on small-scale firms processing grapes as raw materials. Thus, generalising the study findings to other countries with different conditions should be done cautiously. Also, this study used subjective measures, and other studies could use objective measures.

Practical implications

The study helps firm managers understand the importance of supplier relationship management on business performance. The findings also can be used by policymakers to create targeted policies and initiatives that support the firm’s growth and sustainability.

Originality/value

To the best of the researchers’ knowledge, this is the first attempt to find empirical support for the moderating role of logistics capability in supplier relationship management and the business performance of small-scale grapes processing firms in the Tanzanian context.

Abstract

Purpose

This study aims to examine how governing bodies demonstrated stakeholder engagement during the time of the COVID-19 crisis in South Africa.

Design/methodology/approach

This study uses a qualitative approach based on semi-structured interviews with 18 participants, comprising of preparers of financial statements, board members and management consultants/advisors. The study also relied on the analysis of articles on corporate webpages and publications produced by professional bodies on the economic, social and environmental impact of COVID-19.

Findings

The results of this study indicated that governing bodies demonstrated stakeholder engagement during times of crisis through transparent reporting, corporate social responsibility initiatives and active stakeholder inclusivity.

Originality/value

This study contributes to the body of research on stakeholder engagement during a crisis and provides evidence of the role stakeholder inclusivity can play in responding to a crisis. The findings will be useful in understanding the importance of stakeholder engagement during times of crisis. The study is one of the first, to the best of the authors’ knowledge, to evaluate how stakeholder engagement principles can be followed by governing bodies during a crisis.

Abstract

Purpose

The adverse impacts of climate change coupled with rapid informal urbanization in the Southern African region are increasing the vulnerability of already sensitive population groups. Consequently, these urban regions are highly vulnerable to urban heat island effects and heatwaves due to exogenous and endogenous factors. While the dynamic interplay between the built environment, climate and response strategies is known, this paper highlights the lived experience of informal settlement residents. It presents work from a project undertaken in Melusi, an informal settlement in Tshwane, South Africa, as a multi-disciplinary project focusing on improving the local resilience to climate change associated heat stress.

Design/methodology/approach

Following a mixed method approach, a semi-structured observational analysis of the spatial layout and material articulation of selected dwellings along with the continuous monitoring and recording of their indoor environments were undertaken.

Findings

The paper presents the research results in terms of the dwelling characteristics, as spatial and material-use strategies and documented heat stress exposure in these structures. The findings highlight that informal dwellings perform poorly in all cases due to endogenous factors and that inhabitants experience extreme heat stress conditions for between 6 and 10 h daily during the peak summer period.

Originality/value

Currently, there are little empirical data on the heat stress residents living in informal settlements in Southern Africa are experiencing. This article provides insight into the indoor environments of informal dwellings and hopes to contribute future guidelines or heat health policies.
