Age diversity, age discrimination climate and performance consequences-a cross organizational study
This paper deals with the emergence of perceived age discrimination climate on the company level and its performance consequences. In this new approach to the field of diversity research, we investigated (a) the effect of organizational-level age diversity on collective perceptions of age discrimination climate that (b) in turn should influence the collective affective commitment of employees, which is (c) an important trigger for overall company performance. In a large-scale study that included 128 companies, a total of 8,651 employees provided data on their perceptions of age discrimination and affective commitment on the company level. Information on firm-level performance was collected from key informants. We tested the proposed model using structural equation modeling (SEM) procedures and, overall, found support for all hypothesized relationships. The findings demonstrated that age diversity seems to be related to the emergence of an age discrimination climate in companies, which negatively impacts overall firm performance through the mediation of affective commitment. These results make valuable contributions to the diversity and discrimination literature by establishing perceived age discrimination on the company level as a decisive mediator in the age diversity/performance link. The results also suggest important practical implications for the effective management of an increasingly age diverse workforce.

Organizational identity strength, identification, and commitment and their relationships to turnover intention: does organizational hierarchy matter?
In the present study we sought to clarify the functional distinctions between organization identity strength, organizational identification, and organizational commitment. Data were obtained from 10948 employees of a large steel manufacturer. First, confirmatory factor analysis was used to test the discriminant validity of the three focal constructs. Next, drawing on research that suggests hierarchical differentiation may influence individuals' conceptual frame of reference, we examined each focal construct's measurement equivalence across three hierarchical levels (officers, n = 1,056, middle-management, n = 1049, workers, n = 1050). Finally, multigroup structural equation modeling was used to simultaneously estimate the between-group correlations between turnover intention and organization identity strength, organizational identification, and organizational commitment. Results indicated that (a) the measures used to reflect the three focal constructs were empirically distinct, (b) the focal constructs were conceptually equivalent across hierarchical levels, and (c) the pattern of correlations with turnover intention was different for employees with management responsibilities versus workers with no management responsibility. The present findings suggest perceptions of a strong organizational identity, organizational identification, and organizational commitment may influence employees' turnover intention in unique ways, depending on their hierarchical level within the organization.

The positive group affect spiral: a dynamic model of the emergence of positive affective similarity in work groups
This conceptual paper seeks to clarify the process of the emergence of positive collective affect. Specifically, it develops a dynamic model of the emergence of positive affective similarity in work groups. It is suggested that positive group affective similarity and within-group relationship quality are reciprocally interrelated in the form of a self-reinforcing spiral, which is driven by mechanisms of affective sharing and affective similarity-attraction between group members. We label this spiraling relationship 'Positive Group Affect Spiral.' This spiral is proposed to continuously strengthen both the similarity of group members' positive affect and the quality of their interpersonal relationships in a dynamic process. Further, we embed the Positive Group Affect Spiral into a framework of contextual factors that may diminish or strengthen its functioning, considering the potential impacts of charismatic leadership, individuals' or subgroups' organizational cynicism, group and organizational emotion norms, and organizational identity.

Emotion as mediators of the relations between perceived supervisor support and psychological hardiness on employee cynicism
In this study we explore whether emotion experienced at work mediates the relationships between perceived supervisor support, psychological hardiness, and employee cynicism. Data were collected from employees working at a medical technology company located in Switzerland. Mediational analyses showed that employees' positive and negative emotions experienced amidst an organizational crisis fully accounted for the relations between perceived supervisor support and cynicism and psychological hardiness and cynicism. Practical implications and directions for future research are discussed.

Work-related social support modulates effects of early life stress on limbic reactivity during stress
Early life stress (ELS) affects stress- reactivity via limbic brain regions implicated such as hippocampus and amygdala. Social support is a major protective factor against ELS effects, while subjects with ELS experience reportedly perceive less of it in their daily life. The workplace, where most adults spend a substantial amount of time in their daily lives, might serve as a major resource for social support. Since previous data demonstrated that social support attenuates stress reactivity, we here used a psychosocial stress task to test the hypothesis that work-related social support modulates the effects of ELS. Results show decreased amygdala reactivity during stress in ELS subjects who report high levels of work- related social support, thereby indicating a signature for reduced stress reactivity. However, this effect was only observable on the neural, but not on the behavioral level, since social support had no buffering effect regarding the subjective experience of stress in daily life as well as regarding feelings of uncontrollability induced by the stress task. Accordingly, our data suggest that subjects with ELS experiences might benefit from interventions targeted at lowering their subjective stress levels by helping them to better perceive the availability of social support in their daily lives.

Beyond the mean
We develop and test an organizational-level model of the consequences of diversity climate for company performance. Drawing from affective events theory and the organizational climate literature, we highlight the role of idiosyncrasies in employees' diversity climate perceptions. Specifically, we consider diversity climate strength (i.e., agreement in employees' climate perceptions) as a boundary condition of diversity climate's organizational-level effects and expect high climate strength to be particularly beneficial in demographically diverse organizations. Moreover, we introduce collective positive affect as an underlying mechanism of diversity climate's conditional effects on company performance. Hypotheses are tested in a study of 82 German small-and-medium-sized companies with 13,695 surveyed employees. Results show a moderated mediation relationship where diversity climate is only positively related to organizational performance (via collective positive affect) at relatively high diversity climate strength. Although this finding holds for both demographically diverse and homogeneous organizations, post hoc analyses provide initial evidence that a strong climate only helps to realize the effects of diversity climate on collective positive affect when members of age-and gender-related demographic subgroups converge in their climate perceptions. Our study contributes to a better understanding of diversity climate as an effective lever for managing diversity.

Leadership in context: investigating hierarchical impacts on transformational leadership
Purpose - The purpose of this paper is to empirically investigate hierarchical impacts on specific transformational leadership (TFL) behaviors (i.e. idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration).Design methodology approach - Survey data on TFL, job satisfaction, and hierarchy were collected from 448 managers from a multinational corporation in Sweden.Findings - Idealized influence and inspirational motivation occurred more frequently among upper rather than middle managers, while there were no differences for intellectual stimulation and individualized consideration. Also, idealized influence, inspirational motivation, and intellectual stimulation were more effective in strengthening subordinates' job satisfaction among upper rather than middle managers, while individualized consideration was similarly effective in both groups.Research limitations implications - The cross-sectional research design precludes causal conclusions and potentially allows for common method bias. With the main research interest pertaining to hierarchical differences in TFL, however, method bias seems unlikely to fully account for the results.Practical implications - Study results emphasize the necessity to strengthen TFL on lower managerial levels. Organizations might achieve this by cutting administrative constraints and empowering lower level leaders.Originality value - The study addresses repeated calls for a consideration of contextual factors in TFL research. It points to the role of hierarchy as a boundary condition of TFL.

Age, resistance to change, and job performance
Purpose
– In light of the increasingly aging workforce, it is interesting from both a theoretical and practical perspective to investigate empirically the commonly held stereotype that older workers are more resistant to change (RTC). Thus, the main purpose of this paper is to investigate the age/RTC relationship, considering tenure and occupational status (blue/white collar employees) as additional boundary conditions. Furthermore, the paper investigates the relationship between RTC and individual performance, thereby introducing RTC as a mediator in the age/job performance relationship.
Design/methodology/approach
– Study hypotheses are tested among a sample of 2,981 employees from diverse companies. Structural equation modeling with bootstrapping procedures is applied to investigate the moderated-indirect model.
Findings
– Contrary to common stereotypes, employee age is negatively related to RTC. Tenure and occupational status are further identified as boundary conditions for this relationship. Moreover, RTC also shows an association with individual job performance, which allows for the establishment of an indirect-mediation mechanism from age to job performance via the intermediation of RTC. These results can be explained using current life span concepts, particularly the selective optimization with compensation (SOC) model.
Research limitations/implications
– Hypotheses were tested in a cross-sectional data set, which does not allow for conclusions of causality.
Originality/value
– This study contributes to the age stereotyping literature that has thus far neglected the age/RTC relationship. Furthermore, the age/job performance literature is extended by introducing RTC as an important mediating factor. In sum, this study should help provide a more positive and more differentiated picture of older employees in the workplace.

Energy at work: A measurement validation and linkage to unit effectiveness
We introduce the notion that the energy of individuals can manifest as a higher-level, collective construct. To this end, we conducted four independent studies to investigate the viability and importance of the collective energy construct as assessed by a new survey instrument—the productive energy measure (PEM). Study 1 (n=2208) included exploratory and confirmatory factor analyses to explore the underlying factor structure of PEM. Study 2 (n=660) cross-validated the same factor structure in an independent sample. In study 3, we administered the PEM to more than 5000 employees from 145 departments located in five countries. Results from measurement invariance, statistical aggregation, convergent, and discriminant-validity assessments offered additional support for the construct validity of PEM. In terms of predictive and incremental validity, the PEM was positively associated with three collective attitudes—units' commitment to goals, the organization, and overall satisfaction. In study 4, we explored the relationship between the productive energy of firms and their overall performance. Using data from 92 firms (n=5939 employees ), we found a positive relationship between the PEM (aggregated to the firm level) and the performance of those firms.
