This study aims to focus on how smartphone addiction impacts young consumer behavior related to mobile technology (i.e. the compulsive app downloading tendency). After a thorough literature review and following the risk and protective factors framework, this study explores factors that could mitigate its effects (resilience, family harmony, perceived social support and social capital).

The study used the covariance-based structural equation modeling approach to analyze data collected from 275 Generation Z (Gen Z) smartphone users in Spain.

Results suggest that resilience is a critical factor in preventing smartphone addiction, and smartphone addiction boosts the compulsive app downloading tendency, a relevant downside for younger Gen Z consumers.

Through the lens of the risk and protective factors framework, this study focuses on protective factors to prevent smartphone addiction and its negative side effects on app consumption. It also offers evidence of younger consumers’ vulnerability to smartphone addiction, not because of the device itself but because of app-consumption-related behaviors.

In this chapter, we review the historical development of elite theory, and then we propose a way forward beyond it. Elite theory emerged as a critique of democracy in the late 19th century. Although it used historical materials illustratively, it tended to be ahistorical theoretically because its primary aim was to demonstrate the perdurance of elites even in conditions of mass suffrage. Lachmann was the first scholar to develop elite theory as a truly historical and explanatory framework by combining it with elements of Marxism. Even Lachmann's theory, however, remained inadequate because it did not rest on a fully articulated theory of power. In this introduction, we suggest a “relational power theory” as a remedy to this situation, and we use it to formulate a general heuristic for the study of elites, nonelites, and their interrelationships. To illustrate its utility, we show how it can illuminate the chapters in this volume (though they were not necessarily written for these purposes).

The repercussions of Portugal's colonialism are not widely discussed. The marks of colonialism in the public space are still present in the urban landscape of Portuguese cities. Despite the growing activity of the Black movement's in the country, they are still not being systematically considered in the design of public policies. Moreover, the Portuguese census does not include any data collection on ethnic belonging. Therefore, it is difficult to deepen the knowledge of the Black communities. The Black community has been growing in Porto, the second-largest city in Portugal and it remains highly invisible. Starting from a collaborative project between Portuguese and American professionals, acting in the fields of sociology and socially engaged curatorial and contemporary art practices, an experimental approach was developed to map and cocreate with the Black community in Porto. By using digital tools while collecting, analyzing, and sharing data, and by applying an ethnographic approach and techniques of exploration from documentary photography, the team developed a collaborative project side by side with the community. An exchange between disciplinary knowledge and “various subject positions,” with all participants engaging in an exploration of how to begin decolonizing the city through those tools took place at the project TRAVESSIA. This chapter explores how the Black nonelite is expressing and questioning race and ethnic inequalities in Porto by discussing the results of this collaborative project.

The purpose of this study is to examine how informational faultlines on a board affect the management of knowledge owned by directors and the consequences on organizational performance. In this study, informational faultlines are defined as hypothetical lines that divide a group into relatively homogeneous subgroups based on the alignment of several informational attributes among board members.

The study uses unique hand-collected panel data covering 7,247 board members at 106 publicly traded firms to provide strong support for the hypothesized U-shaped relationship. The authors use a fixed effects approach and a system generalized method of moments approach to test the hypothesis.

The study finds that the relationship between informational faultlines on a board and organizational performance is U shaped, with the least optimal organizational performance experienced when boards have moderate informational faultlines. More specifically, informational faultlines within boards are negatively related to organizational performance across the weak-to-moderate range of informational faultlines and positively related to organizational performance across the moderate-to-strong range.

By explaining the mechanisms through which informational faultlines are related to organizational performance, the authors contribute to the literature in a number of ways. By conceptualizing how the management of knowledge plays an important role in the particular setting of corporate boards, the authors add not only to literature on knowledge management but also to the faultline and corporate governance literature.

This study offers a rationale for prior mixed findings by providing an alternative theoretical basis to explain the effect of informational faultlines within boards on organizational performance. To advance the field, the authors build on the concept of knowledge demonstrability to illuminate how informational faultlines affect the management of knowledge within boards, which will translate to organizational performance.

Martial arts and combat sports (MACS) are supported on ritualistic practices which often encompass hazing creating environments where catastrophic masculinities prevail. These forms of masculinities are strengthened inside MACS’ world resonating with masculinities spread out in wider society. We consider this to be the situation found in Brazilian society. With this study, our aim is to analyse how hazing practices in MACS contribute to the production of a socially legitimised catastrophic masculinity in Brazil. Catastrophic masculinity appears as a new concept proposed by Andrade (2022) to define a hegemonic, toxic and tragic form of masculinity spread in Brazil attached to a political power project. We carried out two qualitative empirical pieces of research that focused on three martial arts. These were ethnographic (participant-) observations of various events, training sessions, belt examination and competition and interviews with men participants. Supported by the presented data, we argue that hazing practices end up acting as a means of reproducing the catastrophic masculinity fighters perform in the dojo. They learn and resonate with a pedagogy that requires them to conform to and follow hierarchies through the repetition of the word ‘oss’ as a symbol of submission to arbitrariness. Hazing constitutes, instantiates and reproduces catastrophic masculinity and originates in the same (social) catastrophic masculinity.

The purpose of this article is to untangle the influence of Linda Tuhiwai Smith’s Decolonizing Methodologies on botanical gardens, particularly in the context of commemorating 25 years since its publication. By examining the intersections between decolonial theory and botanical practices, this article seeks to elucidate the ways in which Smith’s work has informed and inspired efforts to decolonize botanical research, conservation and education. Through a narrative review and case study analysis, this article highlights key insights, challenges and opportunities for botanical gardens to embrace decolonial practices and foster more equitable and inclusive relationships with Indigenous communities, science and knowledge systems.

The design and methodology of this article involve a narrative literature review and comparative case study analysis (Petticrew and Roberts, 2006; Goodrick, 2014). The review synthesizes scholarly articles, books and reports on decolonizing botanical practices, focusing on literature that stems from Indigenous science, identifies engagement strategies and advocates for systemic change within botanical institutions. Key themes and recommendations are identified and analyzed to provide insights into future directions for decolonizing botanical gardens. This approach allows for a thorough examination of current discourse and best practices in decolonial theory and botanical research, informing actionable recommendations for advancing decolonization within botanical gardens.

The findings reveal that Linda Tuhiwai Smith’s Decolonizing Methodologies has significantly influenced botanical gardens, inspiring efforts to prioritize Indigenous knowledge systems, deepen community engagement and advocate for systemic change. While progress has been made in integrating decolonial practices, challenges persist, including the need for greater institutional commitment, capacity building and accountability. However, opportunities abound for botanical gardens to continue advancing decolonization, particularly through partnerships with Indigenous communities, educational outreach and policy advocacy. Overall, the findings underscore the importance of ongoing reconciliation and action in cultivating more equitable and respectful relationships that advance principles of Indigenous data sovereignty and governance.

While this article offers valuable insights into the influence of Linda Tuhiwai Smith’s Decolonizing Methodologies on botanical gardens, several limitations must be acknowledged. Firstly, the literature review may not document all relevant transformations undertaken by gardens to date if such initiatives are not documented in the public domain, such as institutional websites. Additionally, the review primarily focuses on English-language literature, limiting the exploration of decolonial practices for botanical gardens in non-English-speaking contexts.

This article holds several practical implications for botanical gardens seeking to decolonize. Firstly, by prioritizing Indigenous knowledge and deepening community engagement, botanical gardens can foster more inclusive and respectful relationships with Indigenous communities. Secondly, advocating for systemic change and policy reforms will address institutionalized inequities and recognize Indigenous People’s rights, including biocultural and intellectual property. Additionally, investing in educational outreach and capacity-building initiatives can enhance institutional and public understanding of decolonization. Overall, embracing decolonial practices can contribute to the adoption and advancement of Indigenous Data Sovereignty and the CARE Principles for Indigenous Data Governance within botanical gardens and beyond.

This article highlights the importance of decolonizing botanical gardens for promoting justice and equity. By centering Indigenous rights to data sovereignty, such as attribution of traditional and biocultural knowledge, botanical gardens can contribute to reconciliation efforts and promote respect for Indigenous rights and sovereignty. Additionally, addressing colonial legacies and systemic inequalities within botanical institutions can advance botanical justice and help build more just and equitable societies. Moreover, this transformation also aligns with a growing legal movement recognizing the inherent rights of Nature, including plant relatives collected, stored and stewarded by botanic gardens.

This article contributes to the literature by exploring the intersection of decolonizing methodologies and botanic gardens, particularly in the context of Linda Tuhiwai Smith’s influential work. By synthesizing key insights and offering actionable recommendations, this review provides guidance on future directions botanic gardens can follow to advance their decolonization strategies and initiatives in furtherance of botanical justice.

Celebrity endorsers are usually considered to bring positive effects to associated nodes, such as brands and corporations. However, limited evidence suggests that brands and corporations are equally responsible for affecting celebrities and their credibility. Drawing on associative network theory, this study explores the effects of brand credibility and corporate credibility on celebrity credibility, both directly and through the mediating and moderating effects of advertising credibility. The research addresses three main issues: (1) whether brand credibility, corporate credibility and advertising credibility have significant effects on celebrity credibility; (2) whether advertising credibility has a significant mediating effect on the effects of brand credibility and corporate credibility on celebrity credibility and (3) whether advertising credibility has a significant moderating effect on the effects of brand credibility and corporate credibility on celebrity credibility.

The study used a quantitative approach involving structural equation modelling. Data were collected from 675 participants from London and focussed on four leading international brands, corporations and celebrity endorsers.

The findings show that brand credibility and advertising credibility have positive direct effects on celebrity credibility; and that advertising credibility mediates the effects of both credibility constructs on celebrity credibility. Furthermore, moderating effects of advertising credibility are also found.

This study will help managers to understand the reverse effects, i.e. the effects of brand credibility and corporate credibility on celebrity credibility. They will be able to understand that a credible brand and corporation like a credible celebrity can also bring significant effects on the associated elements. This will help them to recruit celebrity endorsers who have historically earned their credibility from previous endorsements of credible brands and corporations. Further, these findings will help managers to understand that credibility of the brand and corporation can also affect the credibility of the associated advertising, resulting in having a significant effect on the credibility of the celebrity. This on the consumers’ side will enhance their preferences, attitudes and behaviours, while for the corporation, it will enhance their economic and commercial performance.

This is the first study in the literature, where a conceptual model based on the reverse effects of both credibility constructs on celebrity credibility is examined, directly and based on the moderating and mediating effects of advertising credibility. Hence, the contributions to the literature are threefold: first, the study examines the reverse effect of celebrity endorsement, whereby the credibility of a brand or corporation is transferred to a celebrity endorser; second, the study examines the mediating and moderating effects of advertising credibility on this reverse effect and finally, associative network theory is used to examine the importance of the model.

Research on the underlying mechanisms that transfer the effects of performance appraisal (PA) on employees’ behaviors and intentions remains scarce. The social exchange view of performance appraisal can be a source of deeper understanding about these underlying mechanisms. This study aims to investigate how psychological empowerment (PE) and organizational commitment (OC) explain the link between performance appraisal and three important distal outcomes: voice behavior (VB), organizational citizenship behavior (OCB), and turnover intentions (TOI).

The current study utilizes two wave – two source data from a sample of 250 employees and their supervisors from private organizations in Pakistan and tested the mediation model using SMART-PLS.

Results demonstrated that organizational commitment mediated the effects of performance appraisal on VB, OCB, and TOI, whereas psychological empowerment mediated the effects of performance appraisal on VB and OCB. These results have significant implications for theory and practice.

This study adopts the social exchange perspective to examine the mediation mechanisms linking PA with the three distal outcomes: VB, OCB and TOI. The paper identifies two novel mediators of PA – outcome relationship, i.e., psychological empowerment and organizational commitment.
