Abstract

Purpose

This study investigates the impact of three parameters such as: number of LED chips, pitch and LED power on the junction temperature of LEDs using a best heat sink configuration selected according to a lower temperature. This study provides valuable insights into how to design LED arrays with lower junction temperatures.

Design/methodology/approach

To determine the best configuration of a heat sink, a numerical study was conducted in Comsol Multiphysics on 10 different configurations. The configuration with the lowest junction temperature was selected for further analysis. The number of LED chips, pitch and LED power were then varied to determine the optimal configuration for this heat sink. A general equation for the average LED temperature as a function of these three factors was derived using Minitab software.

Findings

Among 10 configurations of the rectangular heat sink, we deduce that the best configuration corresponds to the first design having 1 mm of width, 0.5 mm of height and 45 mm of length. The average temperature for this design is 50.5 C. For the power of LED equal to 50 W–200 W, the average temperature of this LED drops when the number of LED chips reduces and the pitch size decreases. Indeed, the best array-LED corresponds to 64 LED chips and a pitch size of 0.5 mm. In addition, a generalization equation for average temperature is determined as a function of the number of LED chips, pitch and power of LED which are key factors for reducing the Junction temperature.

Originality/value

The study is original in its focus on three factors that have not been studied together in previous research. A numerical simulation method is used to investigate the impact of the three factors, which is more accurate and reliable than experimental methods. The study considers a wide range of values for the three factors, which allows for a more comprehensive understanding of their impact. It derives a general equation for the average temperature of the LED, which can be used to design LED arrays with desired junction temperatures.

Abstract

Purpose

Consumers nowadays are no longer bystanders in the process of production but are proactive collaborators with the power to co-create value with brands. This study aims to explore the impact of social commerce on the co-creation process of brand value in a social commerce setting.

Design/methodology/approach

A questionnaire survey was conducted online to gather 300 eligible responses. The data were empirically validated using the partial least squares structural equation modelling (PLS-SEM) method.

Findings

The results indicated that brand engagement (BEN) is vital to brand co-creation (BCC) in social commerce, which could be driven by social-hedonic value (SHV) and social information sharing (SIS).

Research limitations/implications

This study stresses the influence of consumer autonomy in the process of BCC by probing the role of SIS. Moreover, by considering the prevailing trend in social media, this study offers a nuanced perspective on the values of social commerce from the viewpoint of SHV.

Practical implications

This study may serve as a useful guide for practitioners to improve their digital outreach strategy on social commerce to forge stronger relationships, encourage further engagements and promote value co-creation within their brand community.

Originality/value

This examines the effect of relationship quality (RQU) and BEN on BCC through a relational viewpoint.

Abstract

Purpose

At times, a traditional minority group that opposes a change in the patriarchal structure is violent toward women who wish to adopt modern lifestyles. This study aims to examine online comments regarding a shooting at a café in an Arab-Bedouin city in Israel, where women were employed as servers. The event was framed in Israeli media as an act of backlash by young men, who call themselves “The Modesty Guard.”

Design/methodology/approach

In this qualitative study, the authors collected 916 online comments that were published on five main online news sites. A thematic and rhetorical analysis of online comments was conducted.

Findings

The findings uncovered five main themes: the expression of support for Bedouin women; ideas for dealing with the Modesty Guard; blaming Bedouin tradition for the shooting; comparison of the violent behavior to a parallel phenomenon among Charedim; and criticism of the lack of treatment by Israeli security forces. The responses reflected a supportive stance toward Arab-Bedouin women, who were open to progress. Conflict discourse, however, expressed alienation and increased social-national schism between the Jewish majority and Arab-Bedouin minority groups in Israel.

Originality/value

This study sheds light on the backlash phenomenon in Negev Bedouin society. Moreover, it exposes the lack of significant supportive actions and a lack of understanding of the deep processes unfolding in this traditional society.

Abstract

Purpose

This article asks how gender, ethnicity and other identities intersect and shape the employment experiences of social workers. During recent decades, governments have contracted social care to for-profit and nonprofit organizations (NPOs) globally as a part of the adaption of the neoliberal approach. Most employees in these organizations are women. However, there is a lack of knowledge about women working in social service NPOs and their unique working environments.

Design/methodology/approach

This article explores the experiences of women employed as social workers in social care NPOs in Israel regarding intersectionality. 27 in-depth interviews were conducted with women social workers working in social service NPOs. Participants reflected diversity in ethnicity, religion and full-time and part-time jobs. Thematic analysis was used.

Findings

The findings shed light on: (1) the contradiction social workers experienced between the stated values of the social care NPO and those values’ conduct, (2) intersectional discrimination among social workers from vulnerable populations and (3) the lack of gender-aware policies.

Social implications

The need to raise awareness of the social care sector and governments to those contradictions and to promote diversity through gender-aware policies and practices.

Originality/value

The article suggests a conceptualization describing gender employment contradictions in social care NPOs, discusses how the angle of intersectionality expands the understanding of the complexities and pressures exerted on social workers from minority groups and emphasizes the need for social care NPOs to acknowledge and deal with these contradictions.

Abstract

Purpose

The aim of this study is to systematise the entrepreneurial coaching (EC) literature by understanding how the phenomenon has been investigated along four dimensions inspired by Gartner’s (1985) conceptualisation of entrepreneurship: entrepreneurial process, context, target and outcomes. In so doing, this study will provide a frame of its multifunctional role and identify relevant gaps and suggestions for future research.

Design/methodology/approach

We conducted a systematic literature review to collect existing works on EC. We analysed 85 selected papers with a qualitative content analysis that allowed us to highlight relevant research themes for the entrepreneurial process, context, outcomes and target.

Findings

Our results demonstrate that EC has a multifunctional role in entrepreneurship that can be summarised in five different typologies, depending on the stage of the entrepreneurial process in which it is applied, the context, the target and the outcomes.

Originality/value

As one of the first attempts to systematise studies on EC, this work extends previous conceptualisation of EC by detailing different typologies of this intervention, thereby contributing to reduced fragmentation and conceptual ambiguity.

Abstract

Purpose

The COVID-19 pandemic is not a foodborne infectious disease, but it has dramatically impacted food safety practices worldwide due to its potential for transmission through contaminated surfaces and food. Accordingly, the Omicron variant seems to have affected food-related activities and behaviours and disturbed food supply networks since its appearance in November 2021. Hence, this paper aims to assess how the Omicron variant impacted food safety knowledge, attitudes and practices amongst adult consumers in five countries: Bosnia and Herzegovina, North Macedonia, Serbia, Montenegro and Russia.

Design/methodology/approach

The study is based on an online survey. The questionnaire was developed and revised based on previous research on the impact of previous COVID-19 waves on food-related activities in several countries. The questionnaire was distributed through the SurveyMonkey platform from January 15 to February 25, 2022. It consisted of 29 multiple-choice and one-option questions organised into three sections. A total of 6,483 valid responses were received. Statistical Package for Social Sciences (SPSS) version 25.0 was used to analyse the survey results.

Findings

According to the survey findings, food safety practices evolved during the Omicron wave in the studied countries. Firstly, less than half of the sample used a face mask whilst purchasing food. Secondly, regarding food safety knowledge, the survey results suggest that there is still a lack of knowledge in the studied countries. Thirdly, the survey indicates a lack of knowledge amongst the respondents regarding food safety attitudes. For instance, more than a third of the sample (34.4%) are unsure whether the COVID-19 virus can be transmitted through food. These results are surprising and alarming, especially considering that our sample has a higher education than the population of the studied countries.

Research limitations/implications

The main limitation of this research is the sample bias. Survey participants were randomly chosen, enrolled voluntarily and not rewarded. As a result, the questionnaire was self-administered and completed exclusively by people motivated by an interest in the topic. Consequently, our survey does not represent the general population of the studied countries. People with a high degree of education and women, for example, were overrepresented in our sample.

Originality/value

This study is unique in that it is the first to gather information and analyse people’s perceptions of the effects of the Omicron variant on food safety. As a result, the findings of this survey offer a solid basis for future investigations into the impact of the pandemic on food safety in the Balkan region and Russia. This study can help further understand the changes during the COVID-19 pandemic. It provides crucial insights that can be used to guide future decision-making and policy development regarding improving food safety practices. This and other future studies will be a foundation for organisational and government readiness for future shocks, crises and pandemics. The effects of the present Ukrainian conflict on agricultural systems and supply chains throughout the globe (e.g. increased food prices) show that this is timely, urgent and highly required.

This study aims to determine the influence of corporate governance characteristics on carbon emission disclosure in an emerging economy.

Abstract

Purpose

This study aims to determine the influence of corporate governance characteristics on carbon emission disclosure in an emerging economy.

Design/methodology/approach

The study is based on S&P BSE 500 Indian firms for the period of 6 years from 2016–2017 to 2021–2022. The panel data regression models are used to gauge the association between corporate governance and carbon emission disclosure.

Findings

The empirical findings of the study support the positive and significant association between board activity intensity, environment committee and carbon emission disclosure. This evinced that the board activity intensity and presence of the environment committee have a critical role in carbon emission disclosure. On the contrary, findings reveal a significant and negative relationship between board size and carbon emission disclosure.

Practical implications

The present study provides treasured insights to regulators, policymakers, investors and corporate managers, as the study corroborates that various corporate governance characteristics exert significant influence on carbon emission disclosure.

Originality/value

The current research work provides novel insights into corporate governance and climate change literature that good corporate governance significantly boosts the carbon emission disclosure of firms. Previous studies examining the impact of corporate governance on carbon emission disclosure ignored emerging economies. Thus, the current work explores the role of governance mechanisms on carbon emission disclosure in an emerging context. Further, to the best of the author’s knowledge, the current study is the first of its kind to investigate the role of corporate governance on carbon emission disclosure in the Indian context.

Abstract

Purpose

The global COVID-19 crisis posed many managerial and leadership challenges for principals. More specifically, after the crisis passed noticeable changes in school climate manifested and affected principal management style. The present study examined perceptions of principals regarding school climate and its impact on management style. The research literature clearly affirms the profound impact of school climate in terms of the relationship between students and school leaders. The study focused solely on religious high schools because, in Israel, the negative impact of the pandemic was most marked there.

Design/methodology/approach

The study was qualitative in nature, and included semi-structured interviews with 10 religious school principals in Israel. Study participants were asked about the existing school climate and their management style in light of the COVID-19 period.

Findings

This study indicated that positive school climate and interpersonal relationships between principals and students were affected by the COVID-19 crisis. Study participants reported that principals had to work arduously in the post-COVID-19 period to restore and improve positive school climate and consequently their management style also needed altering. Specifically, restoring open lines of communication and a sense of belonging as the main components of the school climate were the main foci of principal work. The principals' management style had to be more open and inclusive to restore a sense of belonging and security among students.

Originality/value

The study highlights the importance of an open and inclusive management style to restore positive school climate after crises.

Abstract

Purpose

As sustainable performance has a central role in the small and medium enterprises (SMEs) performance literature, this study aims to examine the influence of networking capabilities in enhancing sustainable performance through knowledge workers’ productivity and digital innovation. It also examines the sequential mediating role of knowledge workers’ productivity and digital innovation on networking capabilities and SMEs’ sustainable performance relationship.

Design/methodology/approach

Data were collected from 308 knowledge workers in the information technology sector and analyzed using the Hayes Process Macro bootstrapping method to test the proposed hypotheses.

Findings

Results indicate that knowledge workers’ productivity and digital innovation individually and sequentially mediate the relationship between networking capabilities and SME’s sustainable (economic and environmental) performance, surprisingly, they do not act as a mediator between networking capability and SME’s social performance. SMEs should prioritize investments in the professional development of their knowledge workers through training and skill enhancement programs. This investment equips knowledge workers with the tools to effectively use the knowledge and resources acquired through networking. Thus, knowledge workers may improve performance by using these resources to tackle challenges.

Research limitations/implications

Although this research focused on this specific context, it is prudent to acknowledge that additional factors may also exert influence on sustainable performance within SMEs, factors that managers may consider when making decisions. Methodologically, the cross-sectional design of this research poses a potential limitation, as it does not allow for the complete elimination of endogeneity concerns. However, it is worth noting that scholars have endorsed the use of cross-sectional data in cases where management researchers aim to expand beyond well-documented and longitudinal data sets.

Practical implications

This research offers practical recommendations for SMEs to improve their sustainable performance through networking. SMEs should seek partnerships with complementary knowledge to improve operations and for other performance-oriented benefits.

Originality/value

This study adds significantly to the literature on sustainable SME performance by studying the interdependent effects of networking capabilities. It also represents the individual and sequential mediation mechanism that links networking capabilities to SME success through knowledge worker productivity and digital innovation.

Abstract

Purpose

In the tourism industry, immersive technologies become increasingly vital, amplifying traveler experiences and industry growth. By studying “e-booking” applications prevalent in hotels, this study aims to analyze the impact of integrating an anthropomorphic virtual agent (AVA) on user perceptions of humanness and service usage intent.

Design/methodology/approach

Two experiments were conducted to examine the effects of using an AVA and explain the psychological mechanism of how AVA’s attributes increase intention to use “e-booking” application.

Findings

The results highlight the positive influence of AVA on the intention to use. They illustrate the psychological mechanism of how AVA’s attributes (agency and emotionality) influence perceived humanness and intention to use. More specifically, the results indicate that perceived humanness mediated the effect of an AVA on intention to use.

Research limitations/implications

Further research should delve into additional capabilities related to humanness.

Practical implications

This study provides useful insights for hotels’ managers about incorporating AVAs in digital services to enhance the perceived humanness of AVAs. The findings suggest that such efforts could yield benefits, especially when they involve conveying that AVAs possess agency and emotionality.

Originality/value

To the best of the author’s knowledge, this study is the first to investigate how AVA impacts hotel human–computer interaction. It examines agency and emotionality features on humanness perception and behavioral intent. It also guides successful digitalized hotel service development and design, expanding existing research on human–virtual agent digital services, which mainly focuses on superficial traits like face and gender.
