The rapid assessment of thick film resistor reliability is presented. This relies on the application of constant power pulses. The long‐term stability of the resistors is predicted on the basis of the value of the minimal destroyed power applied during the pulse. The results are compared with the long‐term behaviour of the tested samples.

The purpose of this paper is to introduce the concept of work group diversity dynamics as a novel approach for studying diverse work groups. The authors profile the dynamic processes within diverse work-groups and provide an overview of main objectives.

The paper draws on years of accumulated diversity research to cast a temporal and dynamic lens on the processes taking place within diverse work groups. After outlining the state of the art in work group diversity research, the definition, overall framework and profile of work group diversity dynamics is offered.

The paper argues that by adopting a temporal and dynamic perspective for studying diverse work groups, one can shift focus from the traditional perspective of “what is diversity” to “what happens within diverse work groups”. The paper disentangles the activities taking place within diverse work groups, defines the actual team processes and finally highlights how these processes might be affected by time and dynamism.

After almost 30 years of diversity research the mechanisms and processes through which diversity is translated into individual and organizational outcomes are not yet sufficiently understood and studied. This paper highlights a temporal and dynamic perspective for studying work group diversity, a view that is yet uncharted in diversity literature.

Due to the proliferation of measures (and conceptualisations) employed to assess shared leadership behaviours, it is unclear to researchers and practitioners which specific team behaviours should be encouraged and which measures should be included in research to enhance team effectiveness outcomes. To address this issue, this research tests 11 shared leadership scales to identify which measures and behaviours exhibit the strongest relationship with team effectiveness.

This research utilises survey methods (n = 328) to test the measurement of shared leadership using 11 previously validated scales. This novel approach uses structural equation modelling techniques (SEM) to compare and contrast multiple measures targeting a single underlying construct.

Across the 11 measures tested (drawn from three theoretical perspectives), no single scale demonstrated a superior ability to assess shared leadership (based on model-fit and effect size exhibited). Nevertheless, the results indicated that measures assessing shared transformational leadership were most highly related to team effectiveness; whilst the shared leadership density measure (using social network techniques) exhibited the weakest relationship.

Limitations of this research include the use of a student sample (although participants were screened based on their current employment in a team environment), and the individual assessment of shared leadership rather than team assessment. These findings indicate that shared transformational leadership behaviours are highly related to perceptions of team effectiveness. It is recommended future research define and delineate between constructs of interest, including general forms shared leadership (i.e. shared leadership broadly defined) and more specific forms of shared leadership (e.g. shared transformational leadership [narrowly defined]).

It is recommended that interventions and/or training designed to enhance team shared leadership outcomes should specifically target shared transformational leadership behaviours; especially when aiming to increase beneficial team outcomes such as effectiveness or potency.

This research is novel in both advancing our understanding of the shared leadership behaviours needed to enhance team effectiveness; and in methodological approaches comparing and contrasting multiple measures of a single latent construct.

Virtual collaboration in teams becomes increasingly popular at work. With the advantages of working in virtual teams come leadership challenges for which the shared leadership theory is discussed as a potential solution. While previous empirical studies investigating shared leadership in virtual teams generally confirm positive effects on team outcomes, this study aims to investigate in detail the leadership behaviors that are typically shared in these settings and how these shared leadership behaviors affect individual level outcomes.

Individuals from different teams participated in a questionnaire study (n = 411). Structural equation modeling was used to assess the effects of shared task- and relations-oriented leadership behaviors on team member’s subjectively perceived productivity and satisfaction with leadership.

Results indicate that shared task-oriented leadership behaviors have a significant positive effect on subjectively perceived productivity and satisfaction with leadership, while relations-oriented leadership behaviors have a significant negative effect. A hypothesis stipulating a moderating effect of task interdependence was not confirmed.

Practical implications include that in virtual teams with hierarchical organizational structures, it may be recommended that task-oriented leadership behaviors are shared among team members, whereas relations-oriented leadership behaviors should remain the responsibility of the official leader.

The findings complement previous research with new insights on behavioral dimensions of shared leadership and their effects on outcomes on the level of the individual.

The purpose of this paper is to develop a clear and generalizable conceptualization of project team momentum, as well as a detailed and engaging research agenda on this concept.

A literature review was conducted to achieve the study’s objectives. The review acknowledges the meanings that researchers in the field of sports have ascribed to the concept of momentum.

The paper develops a multidimensional (cognitive, affective and behavioral) conceptualization of project team momentum, as well as a conceptual framework that clearly distinguishes this construct from its antecedents and consequences.

The paper encourages researchers to adopt the proposed conceptualization of project team momentum and to investigate the questions proposed in the research agenda.

The paper develops a strong conceptual basis for a concept that is highly relevant to, but currently not well-understood in, the project management domain. The proposed conceptualization is likely to contribute to the development of a sound theory of project team dynamics and project success.

This study explores the mediating influences of team reflexivity and workplace spirituality in the shared transformational leadership-team performance relationship.

Adopting the cross-sectional research design, this study collected data from 130 ongoing teams working in India's information technology (IT) sector. The study collected data on shared transformational leadership by adopting the referent-shift consensus method while collecting data on team performance from managers. Thus, the study explored the relationships among the constructs of this research by using multi-source data.

This study has shown that shared transformational leadership induces workplace spirituality and team reflexivity among team members. This research's results show that workplace spirituality mediates the shared transformational leadership-team performance and shared transformational leadership-team reflexivity relationships. This research has also demonstrated that team reflexivity mediates the shared transformational leadership-team performance relationship.

Necessity to facilitate relational job design changes, knowledge sharing, intellectual stimulation is the primary managerial implication of this study. This study also articulates the need to pay attention to create organizational conditions for the emergence of workplace spirituality.

This is the first study that has positioned shared transformational leadership and workplace spirituality as the antecedents of team reflexivity. This research has shown the value and limitation of team reflexivity in ongoing teams.

The purpose of this article is to provide guidelines to help leaders understand and lead virtual teams.

This paper discusses the importance and implementation of effective leadership for virtual teams. It begins with a review of conventional versus virtual teams, and then describes the two primary leadership functions in virtual teams – performance management and team development. Following the discussion of the development and function of new teams, the article then provides a detailed guide for the leadership of virtual teams over the life of a project. These guidelines follow the four stages of a project timeline: Pre‐Project, Project Initiation, Midstream, and Wrap‐Up.

Following guidelines and understanding the differences between conventional and virtual leadership will enable managers to become effective virtual team leaders.

The paper shows how, in the context of increasing globalization and technology, leaders can manage the challenges of leading virtual teams.

This article provides an account of how databases can be effectively used in entrepreneurship research. Improved quality and access to large secondary databases offer paths to answer questions of great theoretical value. I present an overview of theoretical, methodological, and practical difficulties in working with database data, together with advice on how such difficulties can be overcome. Conclusions are given, together with suggestions of areas where databases might provide real and important contributions to entrepreneurship research.

The purpose of this study is to examine the facilitating and inhibiting influence of team-level negative affectivity and conscientiousness on a dyad of emergent states, adopting and comparing both the composition and compilation perspectives.

Data were collected over three time points from 410 undergraduate students nested within cross-functional project teams (N = 62). The data, including individual self-reports and judges’ ratings of team performance, were aggregated to the team-level using both composition (mean) and compilation (skewness) approaches.

The findings indicate that mean-levels of negative affectivity were associated with decreased psychological safety. The use of skewed conscientiousness counterintuitively suggests too many highly conscientious members can also be detrimental to psychological safety. Psychological safety influences team potency and ultimately performance.

The results of this study highlight that the aggregation approach used is important. For example, the use of skewed (but not mean-level) conscientiousness brought an undetected and counterintuitive relationship to light. Future research should use compilation approaches in addition to composition approaches.

Based on path–goal theory and social learning theory, this research is aimed at investigating how authentic leadership can influence team performance in virtual teams, specifically the mechanisms through the mediator of high-quality interpersonal relationships and the moderator of task interdependence.

The valid data of this research were collected from 90 virtual teams including 388 team members and their 90 leaders with a time-lag in China, and then the data were mainly analyzed by the hierarchical multiple regression and bootstrapping method to test the hypotheses.

The research results reveal that authentic leadership can positively influence virtual team performance. High-quality interpersonal relationships mediate the relationship between authentic leadership and virtual team performance. Furthermore, the indirect relationship between authentic leadership and virtual team performance via high-quality interpersonal relationships is moderated by task interdependence.

Team performance as an important kind of team effectiveness is crucial to the virtual team's advantage and success. This research enriches the knowledge on the relationship between authentic leadership and virtual team performance, which contributes to the virtual leadership effectiveness and virtual team management.
