Abstract

Purpose

As additive manufacturing techniques, such as selective laser melting, allow for straightforward production of parts on basis of simple computer-aided design files only, unauthorized replication can be facilitated. Thus, identification and tracking of individual parts are increasingly vital in light of globalized competition. This paper aims to overcome the susceptibility of additive manufacturing techniques for product piracy by establishing a method for introducing and reading out product identification markers not visible by naked-eye inspection.

Design/methodology/approach

Lasers of different nominal power were used for altering the solidification mechanisms during processing in distinct areas of the samples. The resulting local microstructural characteristics and mechanical properties, respectively, were determined by scanning electron microscopy and hardness measurements. The applicability of an advanced eddy current technique for reading out local differences in electro-magnetic properties was examined.

Findings

The findings show that distinct microstructural features are obtained in dependence of the locally applied laser power. These features manifest themselves not only in terms of grain morphology, texture and hardness but also induce changes in the local electro-magnetic properties. The inscribed pattern can be non-destructively visualized by using an advanced eddy current technique.

Originality/value

Conventional copy protection basically consists in supplementary labelling or surface modification. In the present study, a new method is proposed for additively manufactured parts, overcoming the drawbacks of the former methods through process-induced microstructure manipulation. Slight alterations in the electro-magnetic material properties can be detected by advanced eddy current method allowing for identification of arbitrary and inimitable component information in additively manufactured parts.

Abstract

This chapter aims to familiarize the reader with some of the important aspects of tourism geography in the German-speaking countries. It starts with a primarily historical-genetic perspective on tourism development and the theoretical traditions associated with them. The second section describes the structure of the discipline, with a focus on the institutionalization of the field in the universities including their research specialization. The chapter maintains that tourism geography plays a marginal role compared with other subdisciplines of geography, though this is reflected primarily in its institutionalization and less so in the research undertaken. The last section deals with the current challenges and future prospects in German-speaking geographies of tourism from a problem-centered perspective.

Abstract

Organizational behavior scholars have long recognized the importance of a variety of emotion-related phenomena in everyday work life. Indeed, after three decades, the span of research on emotions in the workplace encompasses a wide variety of affective variables such as emotional climate, emotional labor, emotion regulation, positive and negative affect, empathy, and more recently, specific emotions. Emotions operate in complex ways across multiple levels of analysis (i.e., within-person, between-person, interpersonal, group, and organizational) to exert influence on work behavior and outcomes, but their linkages to human resource management (HRM) policies and practices have not always been explicit or well understood. This chapter offers a review and integration of the bourgeoning research on discrete positive and negative emotions, offering insights about why these emotions are relevant to HRM policies and practices. We review some of the dominant theories that have emerged out of functionalist perspectives on emotions, connecting these to a strategic HRM framework. We then define and describe four discrete positive and negative emotions (fear, pride, guilt, and interest) highlighting how they relate to five HRM practices: (1) selection, (2) training/learning, (3) performance management, (4) incentives/rewards, and (5) employee voice. Following this, we discuss the emotion perception and regulation implications of these and other discrete emotions for leaders and HRM managers. We conclude with some challenges associated with understanding discrete emotions in organizations as well as some opportunities and future directions for improving our appreciation and understanding of the role of discrete emotional experiences in HRM.

Abstract

Although stress has become a prominent research theme in consumer behavior and occupational health, to the authors knowledge there is only one review on the relationship between consumer behavior and stress (i.e., when internal and external factors exceed an individual’s resources and endangering the individual’s well-being) and this was published 10 years ago. Further, research on occupational stress has yet to be fully integrated into the consumer stress literature. In this chapter, the authors attempt to advance research on consumer stress by a drawing on a satisfaction mirror framework which outlines that consumers and employees influence each other through a “mirror” where they positively and cyclically influence each other in a service environment. The authors argue that consumers and employees may likewise mirror each other in a negative cycle of stress and well-being depletion. First, the authors describe how stress is viewed in consumer behavior and marketing. Second, the authors review evidence that consumption serves as a form of coping with stress. Third, the authors discuss the role of consumption as a stressor that may drive consumer stress. Finally, the authors introduce the satisfaction mirror model and outline the bi-directional influence on increased stress and well-being depletion at the consumer–employee interface in service encounters. The model introduced in this chapter serves as a framework for organizing findings related to stress and well-being in the fields of consumer behavior and occupational health. In addition, the model serves as a springboard for developing propositions for future research. Ultimately, the authors hope this chapter both updates and builds upon previous findings on stress and consumer behavior, as well as grounds future research on stress and well-being at the intersection of consumers and employees.

Abstract

Despite recent advances, neither organizational studies nor the scholarship on economic resilience has systematically addressed how the ecologies of organizations that populate local economies can serve as infrastructures for responding proactively to economic shocks. Using county-level data, this study analyzes relationships between the prevalence of organizational alternatives to shareholder value-oriented (SVO) corporations within a particular locality and its unemployment levels during and after the Great Recession. The results support the hypothesis that the presence of such alternative organizations can enhance the capacities of local economies to resist and recover from recession shocks. Cooperative, municipal, and community-based enterprises, research universities, and nonprofits more generally were associated with greater resistance to the recession shock and stronger recoveries – specifically, lower surges in unemployment rates from 2007 to 2010 and greater reductions in unemployment rates from 2010 to 2016. By contrast, SVO corporations were associated with greater surges in unemployment and perhaps weaker recoveries. Providing a proof of concept, this study opens up new lines of inquiry for organizational studies by linking organizational ecologies to the promotion of collective efficacy and a more broadly shared prosperity in economic life.

Abstract

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming, powder metallurgy and composite material processing are briefly discussed. The range of applications of finite elements on these subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE researchers/users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for 1994‐1996, where 1,370 references are listed. This bibliography is an updating of the paper written by Brannberg and Mackerle which has been published in Engineering Computations, Vol. 11 No. 5, 1994, pp. 413‐55.

Abstract

Purpose

Advances in material agency driven by artificial intelligence (AI) have facilitated breakthroughs in material adaptivity enabling smart objects to autonomously provide individualized smart services, which makes smart objects act as social actors embedded in the real world. However, little is known about how material adaptivity fosters the infusion use of smart objects to maximize the value of smart services in customers' lives. This study examines the underlying mechanism of material adaptivity (task and social adaptivity) on AI infusion use, drawing on the theoretical lens of social embeddedness.

Design/methodology/approach

This study adopted partial least squares structural equation modeling (PLS-SEM), mediating tests, path comparison tests and polynomial modeling to analyze the proposed research model and hypotheses.

Findings

The results supported the proposed research model and hypotheses, except for the hypothesis of the comparative effects on infusion use. Besides, the results of mediating tests suggested the different roles of social embeddedness in the impacts of task and social adaptivity on infusion use. The post hoc analysis based on polynomial modeling provided a possible explanation for the unsupported hypothesis, suggesting the nonlinear differences in the underlying influencing mechanisms of instrumental and relational embeddedness on infusion use.

Practical implications

The formation mechanisms of AI infusion use based on material adaptivity and social embeddedness help to develop the business strategies that enable smart objects as social actors to exert a key role in users' daily lives, in turn realizing the social and economic value of AI.

Originality/value

This study advances the theoretical research on material adaptivity, updates the information system (IS) research on infusion use and identifies the bridging role of social embeddedness of smart objects as agentic social actors in the AI context.

Abstract

Purpose: Mentioning a criminal’s country of origin in crime news is a divisive and much-discussed issue among both journalists and members of society. Scholars assume that mentioning a criminal’s foreign origin could develop and maintain prejudices against individuals with a migrant background among news recipients. However, until now, no attention has been paid to what increases the likelihood that a journalist does or does not mention a criminal’s country of origin when reporting on crimes. Methodology/approach: One possible explanation is that the frequency and intensity of specific news factors could lead to mentioning a criminal’s origin, since increased importance of a news story is usually assigned when many high-intensity news factors occur. Even though numerous studies have determined the frequency of specific news factors in (crime) news, the explanation hypothesized in this chapter has not yet been examined. To investigate this supposition empirically, a quantitative content analysis of four German prime newscasts (n = 290), including public and private broadcasts, was conducted in the current study. Findings: The findings indicate that mentioning criminals’ origins is still common practice in journalism; furthermore, criminals with foreign origins are explicitly represented as foreign almost ten times more often than German-origin criminals are explicitly mentioned as German. News factors such as personalization, location, and influence show some effects of positively predicting journalistic mentioning of a criminal’s country of origin.
