Abstract

Purpose

The purpose of this paper is to study the high-frequency impacts of fast switching wide-bandgap transistors on electronic and motor designs. The high-frequency power converters, dedicated to driving high-speed motors, require specific models to design predictively electronic and motors.

Design/methodology/approach

From magnetic and electric models, the high-frequency parasitic elements for both electronics and motor are determined. Then, high-frequency circuit models accounting for of parasitic element extractions are built to study the wide bandgap transistors commutations and their impacts on motor windings.

Findings

The results of the models, for electronics and motors, are promising. The high-frequency commutation cell study is used to optimize the layouts and to improve the commutation behaviours and performances. The impact of the switching speed is highlighted on the winding voltage susceptibility. Then, the switching frequency and commutation rapidity can be both optimized to increase the performance of motor and electronics. The electronic model is validated by experimentations.

Research limitations/implications

The method can be only applied to the existing motor and electronic designs. It is not taken into account in an automized global high-frequency optimizer.

Originality/value

Helped by magnetic and electric FEA calculations where the parasitic element extractions are performed. The switching frequency and commutation rapidity can be both optimized to increase the performance of motor and electronics.

Abstract

Meetings can serve the important role of facilitating communication and coordination for systems of teams known as “multiteam systems” (MTSs) that work interdependently to achieve grand societal challenges. Given that MTSs often appear in complex, ambiguous, urgent, and multifaceted task contexts, the MTSs require effective, and efficient but thorough, communication within and between teams in order to achieve shared goals. However, the extant literature regarding the science of meetings has left much to be explored in regard to the inter- and intrateam influences and impacts. This chapter considers the significance of meetings and their practical value in facilitating MTS processes and performance by leveraging what is known thus far regarding MTS structural attributes, their value, their challenges, and opportunities, integrating this foundation with the broader science of meetings. Building on this rationale, the authors move toward empirically and theoretically derived considerations for how meetings may best be designed, facilitated and utilized for MTS effectiveness, as guided by our current understanding of critical MTS attributes.

Abstract

Purpose

The purpose of this paper is to highlight a collaborative effort between academia (University of North Texas, Team Sciences) and practice (Toyota Connected (TC)). This study concentrated on current problems that had been experienced by TC: How to structure and manage multiteam systems (MTSs)?

Design/methodology/approach

This research study utilized a realist systematic review to address an existing problem by working collaboratively with TC and academia. This collaboration involved problem identification, the development of research questions and a full systematic review guided by the research questions.

Findings

This realist systematic review merged the literature with current practices at TC in an effort to gather evidence to support the best method of structuring and managing MTSs. The findings include a leadership structure that incorporates both shared leadership (bottom-up) and existing hierarchical structures (top-down).

Practical implications

The MTS models presented in this study provide new models for organizations/manufacturers/industries to use as a guide when structuring their MTSs.

Originality/value

This study provides an example of a collaborative research effort between practice and academia using a realist systematic review. The paper also provides some multiteam system models that could be implemented and tested in different organizations. Also, new responsibilities and roles for scrum and MTSs are presented as a new method of achieving Agile.

Abstract

Crowdfunding campaigns reflect the personality traits of the entrepreneur, influencing the chances of a successful fundraising. In this study, the authors focus on three different entrepreneurs’ personality dark traits: narcissism, Machiavellianism and psychopathy. Through a text analysis of 338 equity-crowdfunding campaigns in the UK, the authors identified narcissistic expressions used by entrepreneurs in their pitches, and their impact on funding success. The authors found an inverted U-shape relationship between entrepreneurs’ narcissism and the crowdfunding success. On the other hand, entrepreneurs’ psychopathy has a negative linear relationship with crowdfunding success. This study contributes to the entrepreneurship literature, highlighting the importance of displayed entrepreneurs’ personality traits in engaging with crowd investors.

Abstract

Purpose – Cross-national comparisons of crime across the world consistently show that homicide rates are higher in more impoverished countries. However, there is a debate on what aspect of poverty is related to violence. Economics aspects have been conceived as wealth, poverty, and inequality. Furthermore, the impact of economic determinants has never been studied against a second potential determinant, which is the quality of the formal social control mechanisms.

Design/methodology/approach – In this study, we use official data made available by international agencies as well as new and original data from the World Homicide Survey, based on the responses provided by 1,223 respondents located in 145 countries of the world.

Findings – Results show that the two main determinants of the homicide rate are economic inequality (Gini) and the quality of the formal social control mechanisms. However, this second dimension is dependent on the wealth of the nation (gross domestic product) and the prevalence of poverty.

Abstract

Purpose

The purpose of this paper is to present a knowledge-sharing model that explains individual members’ motivation to share knowledge (knowledge donation and knowledge collection).

Design/methodology/approach

The model is based on social-constructivist theories of epistemological beliefs, learning and distributed cognition, and is organized via the mechanism of propositional control, which suggests that attitudes or beliefs largely drive one’s behaviors. This paper also explores how epistemological belief systems may influence behavior processes at work.

Findings

The model presented consists of five epistemological belief dimensions consistent with previous theorization about personal epistemologies. This paper demonstrates how sophisticated (as opposed to naive) beliefs on each of these five dimensions can stimulate one’s intrinsic desire to engage in knowledge-sharing behaviors.

Research limitations/implications

The model is constrained by the assumptions that learning takes place socially and within a specific context (in this case, the team setting), and that a great deal of knowledge sharing is preferred over little knowledge sharing. This paper adds to the understanding of workplace learning by establishing a possible new antecedent to explain the process of how team members are motivated to engage in knowledge-sharing behaviors.

Practical implications

The model may be used for knowledge management and to understand ineffectiveness in teams. It also may assist in human resource functions including selecting and training team members for knowledge-intensive positions.

Social implications

Epistemology affects collaborative relationships. Collaborations and associated knowledge-sharing behaviors among work team members who design and implement products for public use are imperative toward developing products free from health and safety issues.

Originality/value

This paper provides a model for understanding and developing motivation to engage in individual knowledge-sharing behaviors among work team members, which is considered critical toward an organization’s competitive advantage.

Abstract

Purpose

The purpose of this study is to explore how integration teams can build trusting relationships in component teams to enhance their leadership capability within multiteam systems to achieve common superordinate goals. The study investigates how an integration team diagnoses contextual dynamics to enhance understanding of goals in component teams and spans boundaries to create trusting relationships.

Design/methodology/approach

The proposed model was tested by surveying 396 respondents nested within component teams working within five South African manufacturing companies. Structural Equation Modeling was used to analyse the data.

Findings

The study reveals that by diagnosing the contextual dynamics within a multiteam system and through boundary spanning, an integration team builds trusting relationships, which will, ultimately, enable teams to achieve common superordinate goals.

Practical implications

This study offers organisations insights into how multiple component teams of different functional disciplines can work effectively towards achieving an overall or common superordinate goal. It offers insights on how to mitigate misalignment challenges by implementing an integration team within the multiteam system context.

Originality/value

Research participants were employees within a manufacturing context, which sets this study apart from many previous ones conducted in a simulated environment within a military context. The study investigates building trusting relationships among multiple component teams within a multiteam system through the implementation of an integration team, which has not been specifically addressed in previous studies.

Abstract

Purpose

Corporates have recently invested in company-owned makerspaces with the goal to skim the potential of makerspaces as innovation driver. The purpose of this paper is to introduce the first framework describing elements and the innovation-related impact on users of corporate makerspaces (CMSs).

Design/methodology/approach

The CMS framework is based on a critical review of 116 scientific articles on makerspaces and the embedding of the review findings into the corporate context.

Findings

A prototyping infrastructure, a community infrastructure and facilitators are proposed to be key elements of CMSs. Further, CMSs are suggested to have an impact on ideation, concept iteration during the innovation process and collaboration of its users.

Research limitations/implications

The framework on CMSs is based on a critical review of makerspace literature and not on empirical research data.

Practical implications

This paper sheds light on key elements and the expected innovation-related impact of a CMS on the users and thus contains useful information for corporate innovation management on how to plan, build and implement a CMS.

Originality/value

To the best of the authors’ knowledge, this paper is the first review of makerspace literature with focus on their elements and innovation-related impact. Additionally, the review provides the first academic definition of the growing phenomenon of CMSs and describes elements and the innovation-related impact of CMSs on its users in companies, which paves the way for further research on CMSs.

Abstract

Purpose

Deploying hybrid construction project teams (HCPTs) in which the common pattern of interactions is a blend of face-to-face and virtual communications has been increasingly gaining momentum in the construction context. Evidence has demonstrated that effectiveness of HCPTs is affected by a perceived level of virtuality, i.e. the perception of distance and boundaries between members where teams shift towards working virtually as opposed to purely collocated teams. This study aims to provide an integrated model of the factors affecting perceived virtuality in HCPTs, to address the conspicuous absence of studies on virtuality in the construction context.

Design/methodology/approach

An a priori list of factors extracted from existing literature on virtuality was subjected to the scrutiny of 17 experts with experiences of working in HCPTs through semi-structured interviews. Nvivo 10 was deployed for analysing the interview transcripts.

Findings

The findings outline the factors affecting virtuality in HCPTs and map the patterns of their associations as an integrated model. This leads to discovering a number of novel factors, which exert moderating impacts upon perceived virtuality in HCPTs.

Practical implications

The findings assist managers and practitioners dealing with any form of HCPTs (including building information modelling-based networks and distributed design teams) in identifying the variables manipulating the effectiveness of their teams. This enables them of designing more effective team arrangements.

Originality/value

As the first empirical study on virtuality in the construction context, this paper contributes to the sphere by conceptualising and contextualising the concept of virtuality in the construction industry. The study presents a new typology for the factors affecting perceived virtuality by categorising them into predictors and moderators.

Abstract

Purpose

The purpose of this paper is to fill important gaps by using the belongingness theory and examining the effects of individual-level workplace ostracism on members’ voice behavior and the effects of group-level workplace ostracism.

Design/methodology/approach

The authors used samples of 77 groups from a high-technological company.

Findings

Individual-level workplace ostracism is detrimental to group members’ promotive and prohibitive voice behavior, and group members’ belongingness mediates such effect; and group-level workplace ostracism is negatively related to group cohesion. The influence of group members’ perception of ostracism on their voice behavior is contingent on overall level of ostracism.

Originality/value

Despite of a growing body of studies on workplace ostracism “the extent to which an individual perceives that he or she is ignored or excluded by others at workplace”, the effects of workplace ostracism on individual’s voice behavior in group settings have received scant attention.
