Abstract

Purpose

There are very few studies that characterize the properties of the edible part from deep‐water fish species which constitute a new target for developing fisheries. Therefore this paper aimed to examine the balance between health benefits and risks associated to the birdbeak dogfish consumption, with a special emphasis on the assessment of the risks of toxic metal intake.

Design/methodology/approach

Between September 2008 and May 2009, 82 individuals were analysed. The chemical composition (moisture, ash, protein and lipid content), essential elements (zinc (Zn), copper (Cu), iron (Fe), potassium (K), magnesium (Mg) and sodium (Na)), toxic elements (mercury (Hg), cadmium (Cd) and lead (Pb)) and fatty acid composition were determined using standard procedures.

Findings

The species is a lean fish (fat content <2.0 per cent) and for both females and males the mineral concentration in descending order was K>Na>Mg>Fe>Zn>Cu. The edible part of birdbeak dogfish is a good source of several minerals, namely K and Na, reaching respectively ca 18 and 36 per cent of the recommended daily intakes for a 150 g muscle portion. Polyunsaturated fatty acids prevail in the fatty acid composition of both sexes and significant differences between females and males were only found in palmitic acid, arachidonic acid and omega 6. Females attained larger length and higher Hg values. The risk assessment was established for three different consumption scenarios (one and two portions of 150 g per month and one portion of 150 g per week) and showed that only a regular consumption of one portion of a female dogfish per week posed a higher health risk (15 per cent).

Practical implications

This study presents the information about the quantity of shark muscle (in g) to be ingested in terms of the PTWI allowing each consumer to have access to the risks and benefits in eating this fish.

Originality/value

No data existed for fatty acid profile and risk assessment yet and this is the first information on the essential and toxic elements for the European waters.

Abstract

Purpose

Years of research into immigrant entrepreneurship motivation (IEM) call for a synthesis of the field to note field developments and identify thematic antecedents and measurement elements. The paper aims to fill this literature review gap in IEM field. Improving existing analytical frameworks and establishing a research agenda are also goals of the research.

Design/methodology/approach

Adopting the PRISMA procedure, a systematic literature review (SLR) was conducted. This produced 53 IEM research papers (internationally, from 1974 to 2020) from a database search and other sources, each of which was reviewed based on extracted variables, findings and suggestions. A well-accepted entrepreneurial motivation model is used for thematic measurement analyzes.

Findings

IEM research has gained attention over the past 25 years as to the number of publications, research foci and antecedent discoveries. The review suggests that there are six motivational thematic dimensions: individual characteristics, personal experiences and circumstances, personal values, business ideas and opportunities, goal-setting and self-efficacy and immigrant entrepreneurial ecosystem (IEE). The results also reveal a relationship between entrepreneurship motivations and the IEE which is one of the keys recommended future research strands.

Research limitations/implications

This research contributes to entrepreneurship literature by providing a chronological timeline of IEM field development and antecedent discoveries. The review suggests applying the IEE and its associated components to investigate host and home countries’ interactive effects on IEM.

Practical implications

The research provides guidance for policymakers and practitioners concerning available policy instruments and IEM determinants in addition to individual factors.

Originality/value

This study is the first SLR on IEM. It presents a holistic view of the IEM field.

Abstract

“The organisation of any library depends on the men and women who work there. They have a very important job. They are the indispensable middle‐men of culture and science, and in opening this library we ought to remember that its success will depend on them as much as on what is in it.”—The Duke of Edinburgh, opening the Scottish Central Library on November 5th, 1953.

Abstract

Purpose

Corporate diversity encompasses the different talents, knowledge, cultures, experiences and values of its employees. This diversity is reflected in multiple characteristics, such as race, age, gender, social class, religion, sexual orientation, ethnicity, culture and disability. The objective of this study is to identify if diversity is a value driver.

Design/methodology/approach

We take the diversity score from the Diversity Leaders Index 2023 published by Financial Times (FT) and Statista; this will be our independent variable in linear regression models whose objective variables are relevant fundamental indicators of the Euro Stoxx 50 companies. It is, therefore, a cross-sectional sample with financial data taken as of the current date. We have 37 Euro Stoxx 50 components included in the diversity ranking.

Findings

The results indicate that diversity is not a value driver for trading volume, for its revenue, or for systematic risk measured by the beta parameter. However, it is observed, in a confidence interval of 90%, that the most diverse companies are larger (according to their market capitalization). In addition, the most diverse companies are more profitable [return on assets (ROA)] and valued by the market [price to earnings ratio (PER)] in a confidence interval of 95%.

Originality/value

These results indicate that companies should promote corporate diversity as a management strategy, as it is observed that more diverse companies are more profitable and valued by the market. This study provides a quantitative vision in the context of homogeneous companies such as the Euro Stoxx 50 Index on the aspects in which diversity is a value driver.

Abstract

Purpose

The purpose of this study is to empirically investigate the mediating effect of work-life balance (WLB) in the relationship between three significant job resources (namely, job autonomy, supervisor support and co-worker support) and job satisfaction experienced by frontline nursing professionals during the COVID-19 pandemic in an Indian setting using the theoretical foundation of job demands-resources theory.

Design/methodology/approach

Structured questionnaire survey has been used to get the responses from 452 nursing professionals in India during the COVID-19 pandemic. To carry out data analysis structural equation modeling has been used.

Findings

The results reveal the relationship between the framed hypotheses. Surprisingly, the relationship between all three job resources and WLB was found to be positive, and also WLB was positively associated with nursing professionals’ job satisfaction during pandemic situations. However, WLB partially mediated the relationship only between two job resources (namely, job autonomy and supervisor support) and job satisfaction.

Originality/value

The research paper addresses Indian nursing professionals’ perceptions of job resources, WLB and job satisfaction during the COVID-19 pandemic. This paper seeks to examine such a relationship when nursing professionals’ worked round the clock with intuitive expertise and cautiousness to provide quality care and responded more efficiently to scarce resource situations.

Abstract

Purpose

Although social networks play an important role in individual ambidexterity, few studies have examined the impact of salespeople's social networks on sales-service ambidexterity. The purpose of this paper is to explore how salespeople's internal and external social networks affect sales-service ambidexterity.

Design/methodology/approach

The unique data of 331 salespeople from 39 units in retail banking industry and insurance industry were collected, and the hierarchical linear model was adopted to test the hypotheses. Finally, the alternative measure of the dependent variable and the alternative estimation method were adopted for robustness test.

Findings

The results show that the strength of salespeople's internal social networks and the extensiveness of salespeople's external social networks could facilitate sales-service ambidexterity of salespeople separately and synergistically. Salespeople's role breadth self-efficacy partially mediates the influences of internal and external social networks on sales-service ambidexterity, while empowerment climate and transformational leadership positively moderate the aforementioned mediational process by strengthening the relationship between salespeople's role breadth self-efficacy and sales-service ambidexterity.

Practical implications

Practical guidelines are provided for managers to shape ambidextrous salespeople by facilitating salespeople's internal and external social networks, promoting transformational leadership and creating empowerment climate within the unit.

Originality/value

To the best of the author's knowledge, this paper is the first to systematically examine the impact of salespeople's social network on sales-service ambidexterity. Drawing from social cognitive theory and the ambidexterity literature, this research reveals the mechanism of how salespeople's internal and external social networks contribute to sales-service ambidexterity.

Abstract

Purpose

The purpose of this paper is to propose a conceptual framework for the application of blockchain in the Public Distribution System (PDS) in India to manage the supply of food grains to the targeted beneficiaries. The framework will help prevent diversions and leakages of grains at the warehouse and Fair Price Shop (FPS) level. The paper also identifies the enablers and disablers in the context of the framework.

Design/methodology/approach

This paper will firstly review the previous literature in PDS and blockchain-enabled agricultural and food supply chains. The study then proposes a framework that could be implemented in the PDS in India using blockchain technology.

Findings

The proposed framework provides an effective way to combat corruption, exclusion errors of targeted beneficiaries, leakage of PDS food grains and is cost-effective. The identified enablers and disablers give an insight into the application of blockchain in PDS in India.

Research limitations/implications

The research work may have implications for the Ministry of Food and PDS (Central Government), Food Corporation of India and State Governments to manage the supply of the grains more efficiently and effectively.

Originality/value

The current study caters to the implementation of blockchain technology starting from the warehouse level to the FPSs and consumers and simultaneously connecting them to concerned authorities to ensure transparency and accountability.

Abstract

Purpose

Within the framework of EU policies and measures to develop a just and fair green energy transition model. This paper aims to offer valuable insights into a paramount concern not so well debated in the literature, i.e. the spatial variation of energy poverty.

Design/methodology/approach

This empirical analysis investigates the regional variation of energy poverty we draw on a sample of more than 300,000 Spanish households, extracted from the Spanish Household Budget Survey (HBS) for the period 2006–2022. To characterize the probability of a household finding itself in a situation of energy poverty the authors use a discrete choice univariate probit model.

Findings

The results confirm that energy poverty is a phenomenon that is asymmetrically distributed across Spain, and mainly occurs in un-densely populated regions. In addition, the findings demonstrate that the incidence of energy poverty drivers is highly heterogeneous across regions.

Research limitations/implications

The paper ends with some recommendations for policymakers suggesting that countries need to design an energy poverty policy for the households that jointly pursue both a correct identification of vulnerable groups and a match with the type of measure to the characteristics of each region.

Originality/value

This study enhances previous research by considering the case of areas at a lower level of aggregation (i.e. on the NUTS two regions in Spain called autonomous communities) and offers the opportunity to tailor policies to those regions most in need. Furthermore, to provide a more realistic picture of the complex phenomenon of energy poverty, the authors use the information for the period 2006–2022 differentiating by economic micro-cycle. This timespan allows the authors to understand the dynamics of energy poverty in periods of economic crisis, including the effects of the 2008 crisis and the present global energy crisis.
