PurposeThis review provides an overview of the applications of Bambara groundnuts in various food products. The genetic diversity, physical properties and chemical compositions of the crop are also elucidated.Design/methodology/approachThis paper critically reviewed the physicochemical properties and applications of Bambara groundnuts from recent literature.FindingsBambara groundnut (Vigna subterranea) is a drought-tolerant crop from West Africa that contains not only carbohydrates and fats but is also high in protein. The cultivars of Bambara groundnut can be distinguished by the colours of seeds, which range from red, blue-eye, brown and black-eye. Bambara groundnuts contain carbohydrate (57–67%), protein (15–25%), fat (4–8%), fibre (1.4–1.5%) and ash (2.9–4%). As a percentage of protein, the essential amino acids, lysine, methionine and cysteine are relatively high in Bambara groundnuts. Meanwhile, linoleic, palmitic and linolenic acids are the fatty acids present in this crop.Practical implicationsSeveral studies have shown that Bambara groundnuts can be used as fat substitutes, emulsifiers, water binders, bulking agents and thickeners due to its water and oil absorption properties, gelling, pasting, emulsifying and foaming abilities. Bambara groundnuts are used in the development of many intermediate or final products like flour blend, cookies, bread and fermented milk. It has a positive impact on the overall proximate, functional, mineral and amino acid profiles of the food products.Originality/valueDespite its high nutrient density, Bambara groundnuts are an underutilised legume due to unavailability and lack of knowledge among consumers on its benefits. There is a need to promote the use of Bambara groundnuts as a future food.

Modular Ontology

PurposeThe purpose of this paper is to analyze cloud reviews according to the end-user context and requirements.Design/methodology/approachpropose a comprehensive knowledge base composed of interconnected Web Ontology Language, namely, modular ontology for cloud service opinion analysis (SOPA). The SOPA knowledge base will be the basis of context-aware cloud service analysis using consumers' reviews. Moreover, the authors provide a framework to evaluate cloud services based on consumers' reviews opinions.FindingsThe findings show that there is a positive impact of personalizing the cloud service analysis by considering the reviewers' contexts in the performance of the framework. The authors also proved that the SOPA-based framework outperforms the available cloud review sites in term of precision, recall and F-measure.Research limitations/implicationsLimited information has been provided in the semantic web literature about the relationships between the different domains and the details on how that can be used to evaluate cloud service through consumer reviews and latent opinions. Furthermore, existing approaches are lacking lightweight and modular mechanisms which can be utilized to effectively exploit information existing in social media.Practical implicationsThe SOPA-based framework facilitates the opinion based service evaluation through a large number of consumer's reviews and assists the end-users in analyzing services as per their requirements and their own context.Originality/valueThe SOPA ontology is capable of representing the content of a product/service as well as its related opinions, which are extracted from the customer's reviews written in a specific context. Furthermore, the SOPA-based framework facilitates the opinion based service evaluation through a large number of consumer's reviews and assists the end-users in analyzing services as per their requirements and their own context.

The Impact

Purpose – The purpose of this paper is to examine the impact of National Rural Employment Guarantee Scheme (NREGS) on farm sector wage rate. This identification strategy rests on the assumption that all districts across India would have had similar wage trends in the absence of the program. The author argues that this assumption may not be true due to non-random allocation of districts to the program’s three phases across states and different economic growth paths of the states post the implementation of NREGS. Design/methodology/approach – To control for overall macroeconomic trends, the author allows for state-level time fixed effects to capture the differences in growth trajectories across districts due to changing economic landscape in the parent-state over time. The author also estimates the expected farm sector wage growth due to the increased public work employment provision using a theoretical model. Findings – The results, contrary to the existing studies, do not find support for a significantly positive impact of NREGS treatment on private cultivation wage rate. The theoretical model also shows that an increase in public employment work days explains very little of the total growth in cultivation wage post 2004. Originality/value – This paper looks specifically at farm sector wage growth and the possible impact of NREGS on it, accounting for state specific factors in shaping farm wages. Theoretical estimates are presented to overcome econometric limitations.

Critical Choice

Purpose As indicated in the Italian law (No. 109-1996), agri-food co-operatives can also play a role in combatting mafia-type systems by choosing to grow their food products in lands confiscated from mafia-type organisations. These food products provide individuals with a new opportunity to fight criminal organisations on the marketplace. The purpose of this study is to explore how people react to a social marketing initiative devoted to promoting food “buycotting” to counteract mafia-type organisations in Italy. Design/methodology/approach The data were obtained from a convenience sample of 339 Italians, and the study adopted a model inspired by the general theory of marketing ethics. A structural equation model was applied to estimate both the parameter and coefficient functions. Findings Individuals recognise the ethical value of “buycotting”. However, they perceive this form of critical choice as not yet being fully effective in counteracting mafia-type systems in Italy. Practical implications The results suggest that promotional and psychological approaches from marketing literature can be effectively used to influence the consumer’s ethical judgement by selectively communicating and emphasising the benefits of the critical consumption investigated. Originality/value This is one of the first studies to address consumers’ ethical judgments and their reactions towards buycotting food as a critical choice to reward socially responsible corporations.

And Performance

Purpose Corporate governance plays a significant role to overcome agency issues and develop the culture of transparency and openness. In this context, this paper aims to examine how corporate governance mechanisms affect the performance of Islamic banks (IBs). Design/methodology/approach Stepwise, two-step system generalize method of moment estimation technique is used in the analysis in which control variables are added into the model sequentially. This study used data on 129 IBs from 29 Islamic countries (Middle East, South Asia and Southeast Asia) during the period of 2008 to 2017. Findings The findings suggest that the audit committee (AUDC) and Shariah board (SB) have positive impact on the performance of IBs (return on assets and return on equity). However, board size and risk management committee have negative and significant effect on the performance of IBs. CEO duality and non-executive directors have mixed relationship with the performance of IBs. These results support the argument that IBs need to improve their financial performance through appropriate governance mechanism. Research limitations/implications The findings of the study added a new dimension to the governance research that could be a valuable source of knowledge for policymakers and regulators to improve the existing governance mechanism for better performance of IBs. Originality/value The study fills the gap in the literature by addressing the issue of corporate governance on performance of IBs across countries. Agency theory is discussed to explain the relationship between corporate governance mechanism and performance.

Moderated Mediation Model

Purpose The purpose of this paper is to explore the ways in which strategic orientation (SO) and strategic renewal (SR) could create the possibility for improving strategic performance (SP). The indirect effect of SO was also tested in this study. Furthermore, by using the moderated mediation model, the authors also investigated the moderating role of organizational ambidexterity (OA). Design/methodology/approach The results of this cross-sectional study are based on a survey conducted on 1,430 owner/managers of SMEs. To analyze the relationship among variables, this study used descriptive, correlation and hierarchical multiple regression approach. Findings Results revealed that SO positively affects SR and SP in SMEs. Furthermore, the mediating role of SR between the relationships of SO and SP was also confirmed. Moreover, OA strengthens the connection between SO, SR and SP. Practical implications The current study provides new insights for strategic planning and management by focusing on SO along with its different dimensions. Therefore, it provides new guidelines and a roadmap that would be helpful in achieving the objectives of SP. Originality/value The study makes significant contributions to the extant literature by adding new knowledge about the positive impact of SO on SP. Moreover, with the analysis of mediating role of SR in this relationship, the study has made significant addition to the existing literature on SP. Furthermore, moderated mediation model adds value to the existing body of knowledge.

Individual Value

Purpose The purpose of this paper is to determine the differences in the values and behaviours of employees and entrepreneurs and to develop guidelines for employers to foster entrepreneurial thinking in their organisations. Design/methodology/approach To determine individual behaviours, the authors used the career adaptability scale developed by Savickas and Porfelli (2012), complemented with the statements regarding relationships in the workplace and reward, designed by Gattiker and Larwood (1986). The individual values were evaluated by Schwartz’s individual value framework. The career success of individuals was defined by income level and job satisfaction. Data from a sample of 473 respondents were analysed using structural equation modelling. Findings This paper reveals that there are differences in the behaviours and the values of employees and entrepreneurs. Employees are more concerned with relationships at the workplace, rewards and confidence, whereas entrepreneurs focus solely on relationships. Self-direction value has a direct positive impact. Universalism, conformism, achievement, stimulation and safety have indirect positive effects on career success for employees. There is no specific individual value driving career success for entrepreneurs. Originality/value This paper follows the recent trends in organisational culture development whereby organisations seek to incorporate the entrepreneurial mindset at all levels of the organisation. Until now, there has been scarce empirical evidence on the differences between entrepreneurial and employee values. This research provides evidence that the value gap between these two distinct groups is considerable enough to question the ability of the average employee to adopt the entrepreneurial behaviour required by modern organisations.

The Impact

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.

Purpose Value Chain Analysis (VCA) is established as a diagnostic tool. The purpose of this study is to extend existing applications and develop an iterative and relational method. to facilitate the application of VCA to agri-food chains as a strategic process rather than a diagnostic tool. Design/methodology/approach Using a multiple case study design, the new approach to VCA was applied to four Australian prawn fisheries. These fisheries varied in size, location, management structures and marketing arrangements and allowed the general applicability of the approach to be explored. Findings The application of the revised VCA revealed the importance of undertaking a strategic approach, with the outcome for all fisheries being a greater understanding of their consumers and an enhanced realisation of commercial opportunities. Two fisheries completed the revised VCA, and the findings show that a relational approach is crucial in creating value. In addition, it was shown that formalised structures and the informal behaviours of the value chain members have a strong positive impact on the relationship process. Research limitations/implications The research furthers the value chain literature and contributes an iterative approach to the application of VCA. The research also shows that obtaining improvements is not achievable for all chains, and, if the entire chain is not engaged with the process, the value of the results will be compromised. Further research is needed to confirm the validity of findings in other food industries. Originality/value The relational approach is an original contribution to the area of VCA research and provides industry with a blueprint for creating successful value chains. Specifically, the areas of implementation and evaluation make an original contribution to the theoretical and practical knowledge of value chains.

Purpose The purpose of this paper is to study the differentiated impact of factors that influence the propensity to entrepreneur in a sample of people in Chile. A distinction is made between individuals that live in primary cities and secondary cities. The differentiating factors are socio‐cultural aspects (reference models – positive examples of entrepreneurs – and perception of social fear of failure) and the gender of the individual. Design/methodology/approach For the research data from the survey used in Chile by the Global Entrepreneurship Monitor for the years 2010 and 2011 were used. A logit model was used to determine the differentiated impact of the analysed factors and interactions were done using the method proposed by Corneliâen and Sonderhof (2009). Findings These showed that the fact that an individual lives in a secondary city decreases his entrepreneurship probability. The positive impact that the reference models have is weaker in women. Contrary to what was expected, the negative impact of the fear of failure perception is weaker in women. Practical implications These results have the implications to suggest focused public policies and differentiations that consider the socio‐cultural, territorial (focused in cities) and gender aspects. Originality/value The research contributes by giving empirical evidence of the existence of the negative impact of living in a secondary city and of differentiated effects of socio‐cultural factors from the gender perspective.
