The purpose of this study is to present a numerical model for scratched tilting-pad bearings (STPBs) with nonuniform grids. In addition, the model is used to reveal the effects of the structural parameters of bearings on the dynamic characteristics of STPBs under impact loading.

By combining the Reynolds equation, the flow balance equation and the assumption of adiabatic bearings and shafts, a thermo-hydrodynamic model with nonuniform grids of scratched journal bearings was built. Describing the motion of the shaft using the Euler method and introducing the pad-tilting-angle modification equation, a dynamic model of STPBs was established.

The occurrence of scratches in tilting-pad bearings yields great sensitivity to impact loading. Less width-to-diameter ratio and larger clearance ratio reduce the minimum film thickness and enlarge the maximum film pressure, which may lead to bearing collision or abrasion. Moreover, STPBs with larger clearance ratios take longer to recover from impact loading.

This work is original and a valuable reference for the analysis of the dynamic characteristics of STPBs. The effects of other factors on the dynamic characteristics of STPBs can be further investigated based on this model.

The anisotropic surfaces of viscoelastic materials play a role in sliding friction; the purpose of this paper is to study the effect of the anisotropic surfaces on contact area and the friction coefficient.

A complex elastic modulus and an anisotropic power spectrum are used to compute the coefficient of friction based on the extension Persson theory which considers the partial contact and the variation in the roughness slopes.

The ratios of the relative contact area that varies with velocity are obtained with different angles and eccentricities, and the effect of the elastic modulus needs to be considered. The coefficients of the friction parallel to the direction of motion decrease as the angle increases, or as the eccentricity decreases. The friction coefficients in the vertical direction change irregularly when the angles or eccentricities increase.

An extension of Persson’s work considering the partial contact and the effective mean square slope of the roughness is applied to study sliding friction, and the effect of the elastic modulus on contact area is considered.

The purpose of this paper is to understand how firms manage their product and service offerings, integrating supply chain management (SCM) and demand chain management (DCM) strategies. Adding services to the product portfolio of a firm may bring benefits to an organisation, but requires a reconsideration of the supply chain management approach.

A survey is used to collect data, with valid questionnaires obtained for 4,227 UK-based respondents. Empirical analysis utilises structural equation modelling (SEM).

The paper proposes that a combination of management approaches is required by firms which add services to their portfolio of traditional product offerings. A supply chain management approach may be suitable for traditional product offerings. The management of the services value chain, where the customers' role as value creator is a central feature of the construct, is better served by integration of the market orientation of DCM.

The paper addresses a research gap related to the shift in traditional activities carried out by a firm moving from purely product to a product service offer and reconsiders the supply and demand chain management approach. The paper is from a Business to Consumer (B2C) perspective. In this context, the work pioneers analysis into a particular case where a firm's product and service offerings may be substitutes for each other in the eyes of the customer.

The purpose of this paper is to focus on the role ingredient branding (IB) plays in shaping the strategic communications created by public relations/corporate communication departments of large organizations when managing crises.

Starting from a literature review on strategic communication and IB the role of this activity is studied within the Italian context. In order to reach the aim of the paper, primary and secondary sources were exploited generating qualitative and quantitative data. The primary data were gathered though in-depth interviews with key management personnel while the secondary data were sourced from reports made available by Tetra Pak Italy.

The study confirmed the contribution of the strategic proactive role played by Tetra Pak Italy managers of External Relations and Marketing Departments and the communication agency manager during a challenging period of crisis for the company. The main implication of the paper lies in the analysis of the important strategic work implemented by the external consultant of communication together with the External Relations and Marketing managers as members of the dominant coalition.

The paper analyses a Tetra Pak Italy case study, as an exploratory case that could demonstrate how strategic communication – based on an IB campaign – is of fundamental importance during a period of crisis. Moreover, the research studied how proactive and effective the role played by the communication consultant and managers of External Relations and Marketing Departments was as a determinant of resulting outcomes.

The current study examines (1) the relationships among the crisis response, trust and negative behavioral intentions (i.e. avoidance and revenge), (2) the mediation role of trust in the crisis communication of sports organization and (3) the moderation effect of team identification between the crisis response and trust.

A questionnaire was used to collect data from 324 Major League Baseball (MLB) fans who met specific criteria (i.e. background information; knowing about the Houston Astros sign-stealing scandal and how the team responded to it). Confirmatory factor analysis and structural equation modeling were employed to test the proposed hypotheses.

The findings showed that perceived adequacy of the crisis response positively influenced sports fans' perceived trust. This trust was negatively associated with revenge and avoidance intentions. The mediation effect of trust was also found in the relationship between the crisis response and both avoidance and revenge intentions. Regarding the interaction effect of team identification, however, the relationship between the crisis response and trust was not moderated by team identification levels.

The present study contributes to a comprehensive understanding of crisis communication in sports fans' perceptions and behavioral intentions. It illuminates a psychological process through which perceived adequacy of crisis response reduces negative behavioral intentions through trust.

In response to increasing competition for consumer attention, sport governing bodies have innovated short-format, action-oriented versions of traditional sports to attract new fans. This article explores how sport governing bodies (SGBs) manage the need for innovations to both conform to existing stakeholder expectations whilst offering novel benefits in comparison to competition (i.e. legitimate distinctiveness).

Created by the English Cricket Board (ECB), The Hundred competition was used as a case study to explore the conformity-differentiation tension through a legitimacy lens using document and media analysis.

Seven themes were created to explain how the ECB managed legitimacy tensions: rule modification, team creation, scheduling, game-day experience, broadcasting, gender equity and sponsorship. In each theme, differentiation and conformity were traded-off by the ECB to prioritise pragmatic legitimacy with broadcasters and sponsors.

For sport management professionals, the Hundred demonstrates the commercial value of differentiating new sporting events from competitors via hybrid broadcasting partnerships, embedded gender equity and designing game-day experiences that attract hard-to-reach consumer demographics.

SGBs must trade-off legitimacy between sources when innovating to survive, and when faced with conflicting expectations, commercial imperatives determined whether to conform or differentiate.

Most prior studies treated human resource management (HRM) strength as a whole, while neglecting the dynamic interactions between distinct components (consensus, consistency and distinctiveness). The authors lack a deep understanding of how different components operate together to influence burnout. To address these gaps, this study aims to adopt signaling theory to investigate the interactions among different components and their impacts on employee burnout.

The authors collected time-lagged data from 231 full-time employees in manufacturing firms in Suzhou, China. The authors used the PROCESS Model 6 and hierarchical multiple regression to analyze the data.

This study found that HRM system consensus and consistency mitigate employee burnout, whereas HRM distinctiveness is not significantly related to burnout. Furthermore, the authors revealed that HRM system consistency (rather than distinctiveness) mediated the relationship between consensus and burnout. Moreover, the authors found the sequential mediating effects of HRM system distinctiveness and consistency on the association between consensus and burnout.

Considering that employees’ well-being problems may be debilitating and overwhelming during the COVID-19 pandemic, it is particularly ethical and timely for managers to direct attention to the role of HRM system strength in addressing employee burnout.

This study advances the HRM system literature by teasing out the interactions between the three pivotal components of HRM strength. Our study is among the first to empirically investigate the internal relationships between the meta-features of the HRM system and employee burnout. In doing so, the authors develop a more nuanced understanding of the collective nature of a strong HRM system that conveys a shared message about HRM to promote well-being.

When a firm implements certain HR practices, different employees attribute different motives and intentions to the firm with regard to those HR practices. Research on HR attributions has made progress toward understanding the relationship between HR practices and employee outcomes from a process perspective. However, this research is still fragmented and lacks a systematic typology of the different types of HR attributions and a compelling organizing research framework. Furthermore, a number of research gaps and opportunities have emerged regarding the nomological net of employee HR attributions. To address the gaps and capitalize on the opportunities, the authors propose an overarching theory-driven multi-level framework that guides the choice of the antecedents and outcomes of employee HR attributions and explains their relationships along with both mediating and moderating mechanisms. Drawing on signaling theory embedded in the proposed framework, the authors identify and categorize various antecedents of employee HR attributions to explain their relationships. The authors also use several additional theories such as social exchange and the job demands–resources model included in their review to identify and categorize various outcomes of employee HR attributions across levels of analysis (i.e., individual, collective [team/group/unit], organization) and explain their relationships. In addition, the proposed framework explains how individual-level employee HR attributions emerge at the collective level and influence collective processes and outcomes. The authors end their review by pinpointing future research needs and discussing related future research directions.

Human resource (HR) process research emerged as a response to questions about how (bundles of) HR practices related to organizational outcomes. The goal of HR process research is to explain variability in employee and organization outcomes by focusing on how HR practices are intended (adopted) by senior managers, the way that these HR practices are implemented and communicated by line managers, and how employees perceive, understand, and attribute these HR practices. In the first part of this chapter, we present a review of 20 years of HR process research from the start, to how it developed, and is now maturing. Within the body of HR process research, several different research theoretical streams have emerged, which are largely studied in isolation without benefiting from each other. Therefore, in the second part of this chapter, we draw on previous work to propose a staged process model in which we integrate the different research streams of HR process research, recognizing contingencies in the model. This leads us to an agenda for future research and practical implications in the final part of the chapter.

Athletes have leveraged their social platform and reach to advocate for a variety of social causes. Most recently, given the persistent impacts of climate change on sport, the sport sector has been leveraged to engage and educate fans, sport participants, and athletes to promote climate action while consuming sport and in their everyday lives. This chapter conceptualizes the term sport eco-activism and presents a rich history of the early stages of this form of activism and its interaction with sport. Specifically, we provide historical context and examples of how athletes and activist sport organizations (e.g., Surfers Against Sewage, Protect Our Winters) have drawn attention to the impacts of climate change on sport. We also highlight how these entities encourage spectators and participants to change their behaviors and further advocate for collective climate action. In addition, we offer insights on future directions of eco-activism within sport and how such activists can best resonate with their target audiences to create positive change through sport.
