Due to the harsh underground environment in coal mining, the surface of hydraulic support columns corrodes severely, resulting in significant economic losses. Therefore, a highly corrosion-resistant coatings is needed to extend the service life of the columns.

This study aims to compare the corrosion resistance of ST-Cr₃C₂-NiCr (sealed treatment Cr₃C₂-NiCr) coatings with industrially applied chromium plating. The corrosion failure mechanism of the coatings was investigated.

The results demonstrated that the ST-Cr₃C₂-NiCr coatings exhibited excellent corrosion resistance. After sealing treatment, the corrosion potential of Cr₃C₂-NiCr coatings was −0.215 V, and the corrosion current density of Cr₃C₂-NiCr coatings was lower than that of the plated parts.

ST-Cr₃C₂-NiCr coatings prepared by supersonic atmospheric plasma spraying could provide excellent corrosion resistance in the coal industry.

The low porosity and the presence of the NiCr phase were crucial factors contributing to the preferable corrosion resistance exhibited by the ST-Cr₃C₂-NiCr coatings. The corrosive process of the coatings involved layer-by-layer delamination of surface oxide film, sub-surface pitting, formation and degradation of sub-surface passive film, as well as severe block-like delamination.

This chapter focuses on the interplay between visual culture and the construction of masculinities, focusing on the mediated representations of promotional appearances of actors Timothée Chalamet, Paul Mescal, and Barry Keoghan. The chapter examines the site of production of these images and argues that understanding the nuanced production of masculinities extends beyond mere aesthetics, requiring a critical examination of the external narratives and conditions underpinning image creation. The chapter situates these visual representations within the broader politics of their production, offering a lens through which to interrogate the decision-making processes and contextual factors that shape our appreciation of these images. The chapter explains how traditional gender norms are challenged and queered, thereby subverting conventional expectations of cisgender heterosexual masculinity. It critically examines the technological, compositional, and social modalities inherent in image production, revealing how camera technology, stylistic expression, and the symbiotic relationship between images, celebrity culture, and capitalist imperatives influence narrative authenticity and the portrayal of gender. By unpacking the motives behind image production and consumption, this inquiry unveils the complex dynamics of identity, queerbaiting practices, and the commodification of gender and sexuality within media representations. It prompts reflection on the emancipatory potential of visual artefacts against their entanglement with profit-driven agendas and normative constructs, advocating for a vigilant approach to the consumption of visual culture. This critical examination not only challenges existing gender norms but also highlights the susceptibility of images to co-option by dominant discourses, urging a deeper understanding of masculinity in contemporary visual culture.

A key aspect of psychologically informed planned environments (PIPEs), are the attachment theory-informed relationships between residents and staff (Bainbridge, 2017). The key-work provision of one-to-one support from officers to residents is one of the main ways through which relationships are formed. The purpose of this paper is to explore prison officers’ experiences of the key-work role within a PIPE in a women’s Prison in England.

Semi-structured interviews explored ten prison officers’ experiences. Interviews were analysed using thematic analysis.

Five main themes were identified; “Professional support”, “Negotiating Professional Boundaries”, “A Successful Relationship”, “Rupture and Repair” and “Growth for Everyone”. These themes reflected the framework around keywork; what support officers need to cope with the emotional demands of the role, and how to manage challenging situations and build meaningful key-work relationships.

Limitations include the lack of focus on diversity, the impact of the COVID-19 pandemic on officer experience and applicability to other PIPE services. Future research could address some of these limitations.

Practical implications highlight the need for consistent supervision, greater consideration of officers’ transition to the role and trauma-informed training.

The research provides an unprecedented account of prison officers’ experiences of the key-work role, adding to the limited literature within PIPEs in the women’s estate. The supportive nature of the key-work relationship was perceived by officers to contribute towards people’s sentence progression and officers’ personal and professional development.

Police officers in the UK frequently experience traumatic events and work pressures, and these can have a detrimental impact on mental health. A psychological surveillance programme has been implemented and clinically evaluated. This paper reports an economic evaluation of the programme.

A decision analytic model was developed to explore programme costs, outcomes and return on investment for a notional cohort of 1,000 police personnel (officers and staff). The model parameters were obtained from a large data set of sequential psychological surveillance results. Changes in individual work productivity were derived from a workability measure included in the survey.

The modelled expected total cost incurred to screen 1,000 participants was £84,287 ($106,971). The expected net increase in work productivity for those receiving interventions was valued at £241,672 ($306,713). This result represents a return on investment of 187%. Sensitivity analyses showed that the model was robust to changes in key parameters.

Police personnel experiencing traumatic events may need specialist support from occupational health services or psychological therapy. Screening or surveillance can detect mental health problems, but its cost-effectiveness has been previously unknown.

The value for money of providing surveillance within the police force to detect mental health problems is assessed in this research. The gains in terms of increased work are evident. In similar environmental working conditions, this could extend to emergency services globally.

The police are often called upon to deal with the lowest points in people’s lives. The findings have implications for police forces wishing to support officers to be able to provide the best of themselves in these situations.

There have been no previous studies in policing that have concluded that running a psychological surveillance programme in policing is financially viable. Although this requires initial investment, this paper models that the extra costs incurred are more than offset by improved work productivity.

Foreign subsidiaries of multinational enterprises (MNEs) operate in complex and competitive international environments, implement market and non-market strategies, manage resources and value-added activities and contribute to the overall performance of their parent firms. Thus, the research question on the determinants of MNE foreign subsidiaries’ performance is of interest to managers and academic researchers. The empirical literature has flourished over the recent decades; however, the domains are fragmented, and the findings are inclusive. The purpose of this study is to systematically review, analyse and synthesize the empirical articles in this area, identify research gaps and suggest a future research agenda.

This study uses the qualitative content analysis method in reviewing and analysing 150 articles published in 24 scholarly journals during the period 2000–2023.

The literature uses a variety of theoretical perspectives to examine the key determinants of subsidiary performance which can be grouped into six major domains, namely, home- and host country-level factors; distance between home and host countries; the characteristics of parent firms and of subsidiaries; and governance mechanisms (the establishment modes and ownership strategy, subsidiary autonomy and the use of home country expatriates for transferring knowledge from the headquarters and controlling foreign subsidiaries). A range of objective and subjective indicators are used to measure subsidiary performance. Yet, the research shows a lack of broader integration of theories and presents inconsistent theoretical predictions, inconclusive empirical findings and estimation bias, which hinder our understanding of how the determinants independently and jointly shape the performance of foreign subsidiaries.

This study provides a comprehensive, nuanced and systematic review that synthesizes and clarifies the determinants of subsidiary performance, offers deeper insights from both theoretical, methodological and empirical aspects and proposes some promising avenues for future research directions.

Educators have had good reason to be concerned with social justice in a context where diversity has become more pronounced in both our schools and communities, with widening divisions between the advantaged and the disadvantaged. Internationally, increasing emphasis has been placed on utilizing the role of school leadership to address issues of social justice and equality, within a scenario where comparative studies of the performance of educational systems dominate the policy imagination globally, thus leading to increased pressure on school systems. This chapter presents a problematization of the social justice concept within education as presented in the literature, while setting out to critique this concept as an educational goal, as well as the role educational leadership is expected to play in the promotion of equity and social justice discourses through the lens of Actor-Network Theory (ANT). This theoretical chapter has implications for theory, policy, and practice.

The digital platform-based sharing economy has become ubiquitous all over the world. In this paper, we explore how market actors’ conflicting interpretations of digital platforms’ business models give form and shape value co-creation and capture practices in contexts marked by weak institutions and underdeveloped markets.

Integrating insights from the broader literature on digital platforms and the contemporary turn to “meaning-making” in social theory, we adopt a problematization method to unpack the collective contest over the interpretation of value co-creation and capture from ridesharing platforms in contexts marked by weak institutions and underdeveloped markets.

Collective contest over the interpretation of digital business models may give rise to competing meanings that may enable (or impede) digital platform providers’ ability to co-create and capture value. We present an integrative framework that delineates how firms caught up in such collective contests in contexts marked by weak institutions and underdeveloped markets may utilise such conditions as marketing resources to reset their organising logic in ways that reconcile the conflicting perspectives.

The paper presents propositions constituting a contribution to a meaning-making perspective on ridesharing digital platforms by offering insights into how digital business models could potentially be localised and adapted to address and align with the peculiarities of contexts. It goes further to present a theoretical model to extend our understanding of the different sources of contestation of meaning of digital platforms.

The meaning-making perspective on digital platforms extends our understanding of how the collective contest over interpretations of value co-creation and capture may offer a set of contradictory frames that yield possibilities for ridesharing platform providers, and their users, to assimilate the organising logic of digital business models into new categories of understanding.

The current study immerses itself in the realm of diversification prospects within a select group of preeminent global stock exchanges. Specifically, the study casts its discerning gaze upon the financial hubs of the United States, Hong Kong, Germany, France, Amsterdam and India. In this expansive vista of international financial markets, the present analytical study aims to unravel the multifaceted opportunities that lie therein for astute portfolio management and strategic investment decisions.

The study encompasses daily time series data spanning from 2019 to 2022. To assess the interconnectedness among these stock indices, advanced statistical techniques, including Johansen cointegration methods and vector autoregressive (VAR) models, have been applied.

The research outcomes reveal both unidirectional and bidirectional relationships between the Indian, Hong Kong and US stock exchanges, encompassing both short-term and long-term time frames. Interestingly, the empirical findings indicate the presence of diversification opportunities between the Indian stock exchange and the stock exchanges of Germany, France and Amsterdam.

These insights hold significant value for both Indian and international investors, including foreign institutional investors (FIIs), domestic institutional investors (DIIs) and retail investors, as they can utilize this knowledge to construct more effective and diversified investment portfolios by understanding the intricate interconnections between these prominent global stock exchanges.

This research undertaking aspires to bring coherence to a landscape rife with divergent interpretations and methodological divergences. We are poised to offer a comprehensive analysis, a beacon of clarity amidst the murkiness, to shed light on the intricate web of interconnections that underpin the world's stock exchanges. In so doing, we seek to contribute a seminal piece of scholarship that transcends the existing ambiguities and thus empowers the field with a deeper understanding of the multifaceted dynamics governing international stock markets.

This study examines how potentially irresponsible banking operations affect organisational reputation. A moderated mediation model is applied to explain how major aspects of social irresponsibility affect the relationship between consumer awareness of allegedly irresponsible operations, blame and bank reputation. The empirical context is the Swiss franc mortgage crisis that affected the banking industry in most Central and Eastern European countries.

The research study uses data collected from a large survey (N = 1,000) conducted among Polish bank consumers, including those with mortgage loans in Swiss francs. To test the proposed model, the authors use Hayes' process macro.

The findings show that blame fully mediates the effects of corporate social irresponsibility (CSI) awareness on organisational reputation. Three facets of social irresponsibility moderate this relationship. Specifically, the perceived harm and intentionality of corporate culprits cause people to be more likely to blame a bank for the difficulties posed by indebted consumers. At the same time, the perceived complicity of consumers in misselling a mortgage reduces the level of blame and its subsequent adverse effects on bank reputation.

Although a strong reputation is crucial in the financial industry, few studies have attempted to address reputational risk from a consumer perspective. This study helps to understand how potentially irresponsible selling of a financial product can adversely affect a bank's reputation.
