This monograph seeks to summarise the key influences of a role‐based perspective on leadership when making decisions as to how organisational resources can best be deployed.

Application of new frameworks provides insight into the leadership roles executives can adopt when part of formal, informal and temporary groups within the organisation's senior management team and those parts of the organisation for which they are responsible. The methodology adopted is qualitative, focusing on application of previously developed frameworks.

Adoption of an appropriate leadership role, and the timely switch from one role to another as circumstances change, are found to facilitate improvement in the ability of executives to mobilise organisational resources, and in so doing effectively address those challenges with which the organisation is faced.

A one‐organisation intensive case study of a multinational engineering company engaged in the design, development and manufacture of rotating turbomachinery provides the platform for the research. The research intent is to validate two frameworks in a different organisation of a similar demographic profile to those in which the frameworks were developed. The frameworks will require validating in organisations of different demographic profiles.

The concepts advanced, and implications discussed, provide an insight into the role‐based nature of leadership. The practical steps individual executives can take to develop their ability to adopt different leadership roles are highlighted.

This monograph is an investigation into, and study of the contribution of theory that provides insight into, the process by which executives effectively mobilise organisational resources. This differs from the original contributions to theory, which focused on methodology, data gathering and validation in contrast with the current study that is focused on practical application.

Virtual worlds are a typical form of social network syndication. Although the future of the virtual world phenomenon seems bright, not all efforts have succeeded. Therefore knowing how to motivate users and keep them continually engaged and visiting is an important challenge for those who create and manage virtual world websites. This paper aims to address these issues.

The present study proposes a conceptual model from technological, entertainment and social perspectives to examine the determinants affecting users' intentions in their virtual worlds usage. Recognising that human behaviour varies according to different social roles, this study investigated four social roles (habitual, active, personal and lurker), and 729 valid data samples were collected from the Chinese virtual world, i‐Partment. Partial least square and multi‐group analysis were performed to measure the research model.

The results of this study indicate that ease of use, usefulness, social presence and enjoyment are important factors of virtual worlds usage. This study also confirms that social presence and enjoyment are influenced by platform‐based and sociability‐based interactive quality, with sociability‐based interactive quality having a much higher impact on social presence than platform‐based quality. Moreover the proposed model demonstrates different intensities of explanatory power for users' usage intentions according to four social roles, and the results of this study indicate different but insightful findings for each of the four social roles.

The virtual worlds practitioners should strive to launch creative and new recreational information or functions on a regular basis to make users' experiences enjoyable. In addition practitioners should initiate special activities or festivals to promote social interaction and devise rules to encourage users to spend more time on the virtual world websites. Moreover virtual world websites must be easy to use – with a user‐friendly interface, smooth moving lines and clear and understandable information – and provide useful functions.

This paper is one of the few studies that compares and analyses the behavioural models of different social roles, and suggests that virtual world website practitioners should make use of these findings and provide flexible services to fulfil different users' special needs.

This study aims to investigate how social entrepreneurial role models influence social entrepreneurial self-efficacy, social entrepreneurial intent and social entrepreneurial action, with moral obligation as a moderator.

A cross-sectional survey of 261 pupils in the South African province of the Eastern Cape was used in the research study. Structural equation modeling was used to test hypotheses.

The research revealed that having social entrepreneurial role models has a positive impact on both social entrepreneurial self-efficacy and social entrepreneurial intent. In addition, a connection was found between social entrepreneurial intent and entrepreneurial action. The influence of moral obligation was found to be a positive and a significant moderator. Moreover, the association between social entrepreneurial role models and social entrepreneurial intent was mediated by social entrepreneurial self-efficacy.

The findings are not generalizable to nonstudent samples because students constituted the sample for gathering data. Future study therefore requires considering nonstudents to generalize the outcomes. This research should be replicated in other South African provinces and other developing countries for comparative outcomes.

Since social entrepreneurial role models have been practically linked to social entrepreneurship intent and entrepreneurial efficacy, understanding the factors that influence student’s decision to start a social enterprise is critical in South Africa to develop targeted interventions aimed at encouraging young people to start new businesses. Policymakers, society and entrepreneurial education will all benefit from the findings.

This study contributes to bridging the knowledge gap as it investigates how social entrepreneurial role models influence social entrepreneurial self-efficacy, social entrepreneurial intent and social entrepreneurial action, with moral obligation as a moderator. Encouraging social entrepreneurship among South African youth would also help address societal issues. This is a pioneering study in the context of an emerging economy such as South Africa, where social entrepreneurship is so integral.

The primary objective of this research is to explore the underlying mechanisms of social ties influencing lurking behaviour in Microblog by combing role theory and social identity theory.

An online survey of 312 Microblog users in China was conducted to test the proposed research model and hypotheses. The partial least squares (PLS) approach was used to analyse the data.

The results show that social ties affect lurking behaviour on Microblog in two ways, directly and indirectly through role stress. Social ties have a negative direct impact on lurking behaviour. Based on the multiple mediation analysis, social ties positively affect lurking through role overload and negatively affect lurking via role ambiguity. Perceived heterogeneity strengthens the positive effects of social ties on role overload and conflict, and weakens the negative impact of social ties on role ambiguity. Social identification weakens the positive relationship between social ties and role overload and strengthens the negative relationship between social ties and role ambiguity.

This study extends the literature on the social interaction reasons behind lurking behaviour in Microblog by revealing the effects of social ties in Microblog. The theoretical mechanisms of social ties on lurking behaviour in Microblog are unveiled by discovering the direct effect of social ties, the mediating effects of multidimensional role stress, and the moderating effects of different kinds of social identity.

The main purpose of this study is to link work‐family conflict, quality of work and non‐work lives, quality of life and social support (supervisor and spouse supports). Specifically, it seeks to address three different roles of social support that have theoretical and empirical support and the mediating roles of quality of work life and quality of non‐work life.

The SEM‐based approach has been used to study supervisor and spouse supports as moderators between work‐family conflict and quality of life; independent variables of work‐family conflict; independent variables of quality of life. The study has been carried out in Malaysia.

The main findings are: work‐family conflict has relationship with quality of life; quality of work life and non‐work life are “partial” mediators between work‐family conflict and quality of life; and, among the various roles of social support, its role as an independent variable of quality of life gives the best results.

The research is based on a cross‐sectional study conducted in Malaysia and addresses only the spouse and supervisor supports as components of social support.

The research has developed a comprehensive model linking work‐family conflict, quality of work and non‐work lives, and quality of life and has studied the role of social support.

The rise of social media marketing has brought significant implications for advertising industry and its organizations. The traditional role of advertising professionals had been changing from a clear identity to an unclear one. However, previous research has studied relatively little about advertising professionals’ roles and identities or how they may be changing in the social media marketing era. The paper aims to discuss these issues.

A qualitative, interpretive approach was taken in this study. It involved 32 in-depth interviews with advertising professionals in advertising organizations differing in size, digital focus and ownership in different multinational full-service advertising organizations and digital organizations.

The findings indicated that the role of advertising professionals is innovating from a traditional “idea generator” to a “solution facilitator” in response to the social media marketing.

This study identified the key experiences of advertising professionals that they were found to have divergent role identities linked to their identification with traditional and digital organizations.

Only a few concepts in the service literature are as pervasive yet as undertheorized as is the concept of the actor. With a growing interest toward value creation as a systemic and institutionally guided phenomenon, there is a particular need for a more robust conceptualization of humans as actors that adopts a processual, as opposed to a static, view. The purpose of this paper is to build such processual conceptualization to advance service-dominant (S-D) logic, in particular, and service research, in general.

The paper is conceptual and extends S-D logic's institutionally constituted account of the actor by drawing from identity theory and social constructionism.

The paper develops a processual conceptualization of the human actor that explicates four social processes explaining the dynamics between two identity concepts—social and personal identity—and institutional arrangements. The resulting framework reveals how humans are simultaneously constituted by institutions and able to perform their roles in varying, even institution-changing, ways.

By introducing new insights from identity theory and social constructionism, this paper reconciles the dualism in S-D logic's current description of actors, as well as posits the understanding of identity dynamics and the processual nature of actors as central in many service-related phenomena.

This paper is among the few that explicitly theorize about the nature of human actors in S-D logic and the service literature.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Although social networks play an important role in individual ambidexterity, few studies have examined the impact of salespeople's social networks on sales-service ambidexterity. The purpose of this paper is to explore how salespeople's internal and external social networks affect sales-service ambidexterity.

The unique data of 331 salespeople from 39 units in retail banking industry and insurance industry were collected, and the hierarchical linear model was adopted to test the hypotheses. Finally, the alternative measure of the dependent variable and the alternative estimation method were adopted for robustness test.

The results show that the strength of salespeople's internal social networks and the extensiveness of salespeople's external social networks could facilitate sales-service ambidexterity of salespeople separately and synergistically. Salespeople's role breadth self-efficacy partially mediates the influences of internal and external social networks on sales-service ambidexterity, while empowerment climate and transformational leadership positively moderate the aforementioned mediational process by strengthening the relationship between salespeople's role breadth self-efficacy and sales-service ambidexterity.

Practical guidelines are provided for managers to shape ambidextrous salespeople by facilitating salespeople's internal and external social networks, promoting transformational leadership and creating empowerment climate within the unit.

To the best of the author's knowledge, this paper is the first to systematically examine the impact of salespeople's social network on sales-service ambidexterity. Drawing from social cognitive theory and the ambidexterity literature, this research reveals the mechanism of how salespeople's internal and external social networks contribute to sales-service ambidexterity.

The purpose of this conceptual paper is to provide a theoretical explanation for the persistence of the glass ceiling keeping women from assuming leadership positions.

The methodological approach of this paper is to compare and contrast social role theory and expectation states theory as theoretical underpinnings to explain the persistence of a glass ceiling for women leaders.

Both social role theory and expectation states theory belong to the structural/cultural models describing differences between the genders. Social role theory and expectation states theory explicate diverse reasons for the emergence of these differences. However, both theories propose that gender differences will result in evaluation bias against women.

As a result of evaluation bias against women, the glass ceiling phenomenon keeping women from assuming top leadership positions continues to occur.

This paper is being written on the 20 year anniversary of the term glass ceiling being coined. It adds to the body of literature by closely examining two structural/cultural theories as possible causes to an invisible barrier which keeps women leaders from entering top level management positions.
