dding dopants to a powder bed could be a cost-effective method for spatially varying the material properties in laser powder bed fusion (LPBF) or for evaluating new materials and processing relationships. However, these additions may impact the selection of processing parameters. Furthermore, these impacts may be different when depositing nanoparticles into the powder bed than when the same composition is incorporated into the powder particles as by ball milling of powders or mixing similarly sized powders. This study aims to measure the changes in the single bead characteristics with laser power, laser scan speed, laser spot size and quantity of zirconia nanoparticle dopant added to SS 316 L powder.

A zirconia slurry was inkjet-printed into a single layer of 316 SS powder and dried. Single bead experiments were conducted on the composite powder. The line type (continuous vs balling) and the melt pool geometry were compared at various levels of zirconia doping.

The balling regime expands dramatically with the zirconia dopant to both higher and lower energy density values indicating the presence of multiple physical mechanisms that influence the resulting melt track morphology. However, the energy density required for continuous tracks was not impacted as significantly by zirconia addition. These results suggest that the addition of dopants may alter the process parameter ranges suitable for the fabrication of high-quality parts.

This work provides new insight into the potential impact of material doping on the ranges of energy density values that form continuous lines in single bead tests. It also illustrates a potential method for spatially varying material composition for process development or even part optimization in powder bed fusion without producing a mixed powder that cannot be recycled.

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.

Status, which is based on differences in esteem and honor, is an ancient and universal form of inequality which nevertheless interpenetrates modern institutions and organizations. Given its ubiquity and significance, we need to better understand the basic nature of status as a form of inequality. I argue that status hierarches are a cultural invention to organize and manage social relations in a fundamental human condition: cooperative interdependence to achieve valued goals with nested competitive interdependence to maximize individual outcomes in the effort. I consider this claim in relation to both evolutionary arguments and empirical evidence. Evidence suggests that the cultural schema of status is two-fold, consisting of a deeply learned basic norm of status allocation and a set of more explicit, variable, and changing common knowledge status beliefs that people draw on to coordinate judgments about who or what is more deserving of higher status. The cultural nature of status allows people to spread it widely to social phenomena (e.g., firms in a business field) well beyond its origins in interpersonal hierarchies. In particular, I argue, the association of status with social difference groups (e.g., race, gender, class-as-culture) gives inequalities based on those difference groups an autonomous, independent capacity to reproduce themselves through interpersonal status processes.

Research on high-growth firms (HGFs) or gazelles is expanding due to their significant contribution to job growth and economic development. However, the knowledge about the conditions and factors that set these firms on their rapid growth trajectory remains fragmented. Therefore, this chapter provides an abreast inventory of the surging gazelle studies by systematically reviewing the international gazelle growth literature and consolidating firm-level, industry-level, and macroeconomic-level growth factors and their interactions as elaborated in the studies. Based on the review of 62 international empirical studies, this chapter finds that the gazelle growth is complex and multidimensional in its scope and nature. The firm’s growth intention and entrepreneurial nature emerge as necessary but not sufficient conditions to guarantee rapid growth as it results from the impact of and interaction between various firm-level and external factors. The different growth-influencing factors are summarized using a theoretical gazelle growth model, which supports the rare and temporal nature of the gazelle growth.

We develop a multilevel model of emotional processes grounded in social identity theory to explore the role of emotion in transformational leadership.

This work is conceptual in nature and develops theory surrounding emotion in organizations by integrating theories on transformational leadership, emotion management, and organizational identity.

Transformational leaders utilize interpersonal emotion management strategies to influence and respond to emotions arising from the self-evaluative processes of organizational members during times of organizational identity change.

The conceptual model detailed provides insight on the intersubjective emotional processes grounded in social identity that influence transformational leadership. Future research into transformational leadership behaviors will benefit from a multilevel perspective which includes both interpersonal emotion management and intrapersonal emotion generation related to social identity at both the within-person and between-person levels.

The proposed model expands on the role of emotions in transformational leadership by theoretically linking the specific transformational behaviors to discrete emotions displayed by followers. While previous empirical research has indicated the positive outcomes of transformational leadership and the role of emotion recognition, work has yet to be presented which explicates the role of discrete emotions in the transformational leadership process.

Display rules are formal and informal norms that regulate the expression of workplace emotion. Organizations impose display rules to meet at least three objectives: please customers, maintain internal harmony, and promote employee well-being. Despite these valid intentions, display rules can engender emotional labor, a potentially deleterious phenomenon. We review three mechanisms by which emotional labor can create worker alienation, burnout, stress, and low performance. Though not as widely discussed, emotional labor sometimes has propitious consequences. We discuss the potential benefits of emotional labor as well.

Brands are increasingly reflecting social values, and many brands have begun to embrace equality and inclusivity as a marketing strategy. Accordingly, consumers are increasingly being exposed to brands associated with different social groups. This paper aims to examine how consumers who have experienced pride respond to brands associated with dissociative out-groups.

Four studies were conducted. Study 1 tested the basic effect of how the experience of different facets of pride affects consumers’ brand attitudes toward a brand associated with a dissociative out-group. Studies 2 and 3 examined the underlying mechanism of consumers’ psychological endorsement of egalitarianism using both mediation and moderation approaches. Study 4 derived implications of our findings for marketers.

The results show that consumers respond differently to a brand associated with a dissociative out-group based on the facets of pride they experience. When consumers experience authentic (vs hubristic) pride, they exhibit a more favorable attitude toward the brand associated with the dissociative out-group. This is because authentic (vs hubristic) pride increases consumers’ psychological endorsement of egalitarianism, which enhances consumers’ brand attitudes toward the brand associated with the dissociative out-group.

The findings suggest that brand managers should think about ways to elicit consumers’ authentic pride to minimize the potential backlash from consumers when promoting equality and inclusivity in their brand communications, particularly when such communications contain cues of dissociative out-groups.

This paper contributes to the branding literature by identifying pride as an important determinant that can help brands overcome the negative impact of dissociative out-groups on consumers’ brand reactions, enriches the literature on pride by documenting a novel effect of the two facets of pride on consumer behavior and extends the literature of egalitarianism by demonstrating pride as a driver of consumers’ psychological endorsement of egalitarianism.

Building upon relational leadership theory, we develop a theoretical model examining the association between leader-follower congruence in follower role orientation and manager and subordinate relational and well-being outcomes. Follower role orientation represents individuals’ beliefs regarding the best way to enact a follower role. We predict that managers and subordinates who share similar role orientations will experience higher quality leader-member exchange (LMX) relationships and greater eustress than those who differ in their follower role orientations. Propositions are presented for direct effects between congruence and stress and indirect effects through LMX. Our theoretical model contributes to nascent research on followership by offering greater understanding of manager and subordinate beliefs regarding how followers should enact their roles, and the importance of considering leader (i.e., manager) as well as follower outcomes in the workplace. It also extends current thinking about stress as an important outcome of leader-follower relationships.

Cites that the Supreme Court has played a significant role in shaping the meaning and scope of employment discrimination legislation through a handful of significant cases. Stresses that these decisions are important for managers to be aware of, in order to enforce employment legislation within their companies. Discusses three very important cases which are recognized as the most significant employment discrimination rulings, often used as precedent in other cases. Covers other, more recent cases, which also offer some significant decisions in dealing with issues that have evolved recently.
