Abstract

Purpose

The effect of bolt stripping failure on the ductility of steel end plate beam-column connections has received relatively little investigation to date. The objective with the present work is to establish a validated numerical model of end plate connections at elevated temperatures, which predicts the mechanical behaviour and failure modes observed in the experimental tests including the bolt stripping failure. Furthermore, the validated FE model was used to investigate the effect of stripping failure on both the rotational and load-bearing capacity of end plate connection.

Design/methodology/approach

The analysis was conducted on a validated numerical model of end plate connections at elevated temperatures, which predicts the mechanical behaviour and failure modes observed in the experimental tests including the bolt stripping failure. The material was modelled considering ductile damage initiation and evolution featured in ABAQUS/Standard.

Findings

This study demonstrates that thick end plates can prevent stripping failure which significantly improves the rotational capacity of the connection. This failure mode can develop readily with thin end plates; however the effect is often unrealistically mitigated through idealised experimental tests. The rotational capacity of a connection can be 5.0 times higher if stripping failure is avoided, particularly at elevated temperatures. Eurocode 3 part 1.8 does not consider the possibility of stripping failure when discussing the requirements for plastic analysis. It is concluded in the present study that by allowing for the possibility of bolt stripping, the mode of failure can often shift from end plate failure to bolt stripping, this in turn significantly reduces the connection rotational capacity.

Originality/value

The effect of bolt stripping failure on the ductility of steel end plate beam-column connections has received relatively little investigation to date.

Abstract

Purpose

The purpose of this study was to explore the differences in motivation for sport consumption within a diverse sample of college students with underrepresented identities.

Design/methodology/approach

Data were collected from 2,833 students at universities in a mid-major Division I FBS athletic conference through a survey. Two MANOVAs were conducted to examine group differences. While the first MANOVA compared a dominant group (White and non-LGBTQ+) to an underrepresented group (non-white race and/or LGBTQ+), the second MANOVA explored differences in five specific marginalized groups (Asian, Black or African American, Hispanic or Latino, LGBTQ+, intersectional marginalized identities).

Findings

The results indicated that the dominant group scored significantly higher than the combined underrepresented group in four of the eight sport consumption motives examined. However, the comparison of individual underrepresented groups showed significant differences for all eight consumption motives between at least two underrepresented groups.

Originality/value

This study is the first attempt to compare group differences in motivation for sport consumption between specific racially marginalized groups, LGBTQ + community members, and intersectional racial and LGBTQ + identities within college athletics.

Abstract

Purpose

Human resource development (HRD) poses complex challenges for scholars and practitioners due to its elusive nature in definition, scope, and boundaries. Driven by lived experiences, this integrative literature review aims to explore the complexities of HRD, focusing on its conceptualizations, boundaries, and trajectories from 1990 to 2023.

Design/methodology/approach

Using Callahan’s (2014) Six Ws, Page et al. (2020) Preferred Reporting Items for Systematic Reviews and Meta-Analyses search process, and Lester et al. (2020) thematic analysis, 26 peer-reviewed articles from leading HRD journals and databases were analyzed.

Findings

This literature review’s findings enhance our understanding of HRD’s trajectory by illuminating its tumultuous beginnings, precarious present, and uncertain future – potentially even its demise. The author urges prominent HRD scholars to take decisive action to secure the discipline’s future before it is too late.

Research limitations/implications

One limitation is the reliance on specific articles for data analysis. The propensity to emphasize only the prevailing viewpoint is a constraint inherent in literature reviews (Dickson et al., 2011). Another limitation is this study’s reliance on articles exclusively from English-speaking literature. By focusing solely on publications in English, this study overlooked HRD literature published in other languages, potentially excluding valuable insights and perspectives from non-English-speaking regions and cultures.

Originality/value

Over the years, the debates regarding the definition of HRD have been fraught with ambiguity and contradictions. The boundaries of HRD remain similarly nebulous, with scholars debating its scope and applicability across contexts. This literature review adds to this debate from a unique perspective.

Abstract

Purpose

The purpose of this paper is to highlight suicide risk factors experienced by graduate students and postdoctoral scholars, and then outline suicide prevention strategies for these populations.

Design/methodology/approach

Through analysis of literature and application of theory, the authors use the diathesis-stress model and Joiner’s (2005) interpersonal theory of suicidality to outline suicide prevention strategies specific to graduate students and postdoctoral scholars.

Findings

The authors’ review of the literature and application of theory suggest that both individuals and groups can engage in suicide prevention strategies, specifically pertaining to reducing stressors unique to graduate students and postdoctoral scholars, as well as addressing feelings of thwarted belongingness and perceived burdensomeness that can lead to the development of suicidality within these populations.

Practical implications

Engaging in suicide prevention strategies can save lives and address the mental health conditions exhibited among graduate student and postdoctoral scholars.

Originality/value

The authors offer a synthesis of good practices addressing suicide risk factors and prevention with attention to the stress-diathesis model and Joiner’s (2005) interpersonal theory of suicidality toward reducing suicidality among graduate students and postdoctoral scholars.

Abstract

Purpose

This study examines the effects of a firm’s corporate social responsibility (CSR) initiative on its employees’ organizational attachment and intent to leave. We propose that employees’ perceived authenticity of their firm’s CSR activity mediates the effects of a firm’s CSR initiative on employees’ attachment to the firm and intent to leave. We also hypothesize that employees understand the authenticity of their firm’s CSR initiative based on internal and external attribution mechanisms. We propose that internal attribution enhances authenticity, while external attribution reduces it.

Methodology/approach

We surveyed a sample of 450 employees from 38 Korean companies that were included in the 2009 Dow Jones Sustainability Index Korea (DJSI Korea). To test the theoretical model, we employed a linear structural equation modeling which allows the causal estimation of theoretical constructs after taking into account their measurement errors.

Findings

As predicted, internal attribution significantly increases employees’ perceptions of their firm’s CSR authenticity, whereas external attribution significantly reduces such perceptions. Employees’ perceptions of authenticity, in turn, increase their affective attachment and decrease their intent to leave. In addition, the effects of the two attribution mechanisms on organizational attachment and intent to leave were mediated by employees’ perceptions on authenticity.

Research limitations/implications

Research on authenticity has been case studies or narrative ones. This is one of the first studies investigating the role of authentic management empirically.

Practical implications

We demonstrate that a firm’s CSR initiative is a double-edged sword. When employees perceive inauthenticity of their firm’s CSR initiative, the CSR initiative could be detrimental to employees’ attachment to the firm. This study calls attention to the importance of authentic management of CSR.

Social implications

Informational transparency through social network services become the foundational reality to the contemporary management. To maintain competitive edge in this changing world, every stakeholder of a firm including managers, employees, customers, shareholders, government, and communities should collaborate and help each other live the principle of authenticity.

Abstract

This paper illuminates the distinction between individual and organizational actors in business-to-business markets as well as the coexistence of formal and informal mechanisms of coordination in multinational corporations. The main questions addressed include the following. (1) What factors influence the occurrence of personal contacts of foreign subsidiary managers in industrial multinational corporations? (2) How such personal contacts enable coordination in industrial markets and within multinational firms? The theoretical context of the paper is based on: (1) the interaction approach to industrial markets, (2) the network approach to industrial markets, and (3) the process approach to multinational management. The unit of analysis is the foreign subsidiary manager as the focal actor of a contact network. The paper is empirically focused on Portuguese sales subsidiaries of Finnish multinational corporations, which are managed by either a parent country national (Finnish), a host country national (Portuguese) or a third country national. The paper suggests eight scenarios of individual dependence and uncertainty, which are determined by individual, organizational, and/or market factors. Such scenarios are, in turn, thought to require personal contacts with specific functions. The paper suggests eight interpersonal roles of foreign subsidiary managers, by which the functions of their personal contacts enable inter-firm coordination in industrial markets. In addition, the paper suggests eight propositions on how the functions of their personal contacts enable centralization, formalization, socialization and horizontal communication in multinational corporations.

Abstract

The purpose of this chapter is to examine the linkages between negative life events (e.g., exposure to community violence and personal challenges) and antisocial behaviors. The participants are 170 African American male adolescents, who resided in urban communities in the United States. The results supported the hypothesis that exposure to community violence mediates the relation between African American male youth’s personal challenges and antisocial behaviors. Thus, the personal challenges that many African American males face may have direct linkages to antisocial behaviors. But, without examining the context in which African American adolescent males grow up, an incomplete story is chronicled.

Abstract

Purpose

This study aims to examine the following across a six-month period in post-graduate research (PGR) students: mental health and well-being; the effect of academic pressures on depression, anxiety and well-being; and the extent to which psychological resilience buffered against academic pressures.

Design/methodology/approach

This was a longitudinal questionnaire study with predictor variables of six types of academic pressure, outcome variables of depression, anxiety and well-being, and a moderator of resilience.

Findings

Well-being significantly worsened across the six-month timeframe, but levels of depression and anxiety remained relatively stable. Negative perceptions of academic challenges at baseline significantly predicted anxiety, but not depression or well-being, six months later. Negative appraisals of relationships with supervisors, other university staff and work peers were not predictors of anxiety. Social support resilience which was present at baseline buffered the relationship between perceived academic challenges and anxiety.

Practical implications

Higher education institutions have a duty of care towards PGR students, many of whom struggle with the escalating interactions between mental health problems and academic pressures. Actively nurturing psychological resilience related to social support is key at the level of individual students and the PGR community but more broadly at an institutional level.

Originality/value

To the best of the authors’ knowledge, this is the first study to examine the effects of negative perceptions of multiple facets of academic life on depression, anxiety and well-being longitudinally. Additionally, it is the first study to investigate, and demonstrate, the extent to which psychological resilience can lessen the relationship between academic challenges and anxiety over time.

Abstract

Purpose – Driver distraction and other forms of driver inattention remain significant road safety problems. The purpose of this chapter is to explore recent developments in theoretical and empirical research on driver distraction and inattention and provide the reader with a sense for, and understanding of, the key issues.

Methodology – Key references from the literature are reviewed and discussed.

Findings – First, we discuss one way of conceptualising the distinction between driver distraction and other forms of inattention, as well as the mechanisms which may underlie these forms of inattention. Second, we underscores how driver distraction may derive from a plethora of sources, and how the potential for performance degradation deriving from driver interaction with these sources may be moderated by a range of factors. Third, we review recent literature on the types of impairments in driving performance and safety associated with driver distraction. Fourth, we outline recent literature on driver distraction and inattention in the realm of highly automated vehicles that will drive the transport future. Finally, we discuss some promising strategies aimed at preventing and mitigating the impact of driver distraction.

Research implications – There are many gaps in the driver distraction literature that need to be addressed. In addition, further research needs to be undertaken to examine the role of driver distraction in the realm of highly automated vehicles.

Practical implications – The findings point towards of a range of injury prevention countermeasures that have potential to prevent and mitigate driver distraction.

Abstract

Purpose: The development of service automation continues to underpin the travel, tourism and hospitality sectors providing benefits for both customers and service companies. The purpose of this chapter is to showcase the practice of self-service technology (SST) usage in the contemporary tourism and hospitality sectors and present a conceptual framework of customer SST adoption.

Design/Methodology/Approach: This chapter offers an examination of theory, research and practice in relation to SST usage in tourism, highlighting the benefits and drawbacks arising for both customers and service providers. Since the benefits are achieved only if SSTs gain effective adoption with customers, this chapter focuses on concepts underpinning the study of customer SST adoption. Drawing on SST adoption factors and SST customer roles, a conceptual framework of SST adoption is discussed.

Findings/Practical Implications: This chapter examines the principles and practice underpinning the usage of self-service technologies in the travel, tourism and hospitality sectors, with specific reference to customer SST roles in co-creation. The customer SST roles provide a more detailed and nuanced picture of the customer perspective on SST usage. These nuanced roles are captured in a conceptual framework which seeks to further refine the understanding of customer SST adoption.

Research Implications & Originality/Value: The framework provides a useful foundation for further research with a focus on customer empowerment in SSTs. The future development of service automation will require a balance between the delivery of a personalised and smarter customer experience and technology applications that are unobtrusive and which do not pose any ethical or privacy concerns.
