Advanced fibre-reinforced polymer (FRP) composites have been increasingly used over the past two decades for strengthening, upgrading and restoring degraded civil engineering infrastructure. Substantial experimental investigations have been conducted in recent years to understand the compressive behaviour of FRP-confined concrete columns. A considerable number of confinement models to predict the compressive behaviour of FRP-strengthened concrete columns have been developed from the results of these experimental investigations. The purpose of this paper is to present a comprehensive review of experimental investigations and theoretical models of circular and non-circular concrete columns confined with FRP reinforcement.

The paper reviews previous experimental test results on circular and non-circular concrete columns confined with FRP reinforcement under concentric and eccentric loading conditions and highlights the behaviour and mechanics of FRP confinement in these columns. The paper also reviews existing confinement models for concrete columns confined with FRP composites in both circular and non-circular sections.

This paper demonstrates that the performance and effectiveness of FRP confinement in concrete columns have been extensively investigated and proven effective in enhancing the structural performance and ductility of strengthened columns. The strength and ductility enhancement depend on the number of FRP layers, concrete compressive strength, corner radius for non-circular columns and intensity of load eccentricity for eccentrically loaded columns. The impact of existing theoretical models and directions for future research are also presented.

Potential researchers will gain insight into existing experimental and theoretical studies and future research directions.

This paper attempts to assess the transit service reliability with taking into account the interaction between network performance and passengers' travel choice behaviors. Besides the well-known schedule reliability, a waiting-time reliability is newly defined as the probability that the passengers' average waiting time is less than a given threshold. A Monte Carlo simulation approach, which incorporates a stochastic user equilibrium transit assignment model with explicit capacity constraints and elastic frequencies, is proposed to estimate the above two reliability measures of transit service. A numerical example is used to illustrate the applicability of the reliability measures and the proposed approach.

For decades organizational citizenship behavior (OCB) has been of interest to scholars and practitioners alike, generating a significant amount of research exploring the concept of what citizenship behavior is, and its antecedents, correlates, and consequences. While these behaviors have been and will continue to be valuable, there are changes in the workplace that have the potential to alter what types of OCBs will remain important for organizations in the future, as well as what types of opportunities for OCB exist for employees. In this chapter we consider the influence of 10 workplace trends related to human resource management that have the potential to influence both what types of citizenship behaviors employees engage in and how often they may engage in them. We build on these 10 trends that others have identified as having the potential to shape the workplace of the future, which include labor shortages, globalization, immigration, knowledge-based workers, increase use of technology, gig work, diversity, changing work values, the skills gap, and employer brands. Based on these 10 trends, we develop propositions about how each trend may impact OCB. We consider not only how these trends will influence the types of citizenship and opportunities for citizenship that employees can engage in, but also how they may shape the experiences of others related to OCB, including organizations and managers.

In this chapter, we assume the following: (1) the root cause of most organizational problems is culture and leadership, (2) executives seldom want to deal with these root causes, (3) because life is uncertain, organizational change is an emergent process, (4) most change processes unfold by reconstructing social reality, (5) the change process is inherently relational, (6) effective change efforts are enhanced by increasing the virtue of the actors, (7) change is embedded in the learning that flows from high-quality relationships, and (8) change agents may have to transcend conventional, economic exchange norms in order to demonstrate integrity and to build trust and openness. Drawing on the field of positive organizational scholarship, we focus on the change agent. We review the literature on self-change and offer several paths for becoming a positive leader.

In this chapter, we develop and present the Multi-Perspective Multilevel Model of emotional labor in organizations. This model is based on three perspectives: (1) a service requirement, (2) an intra-psychic process, and (3) an emotional display, each involving five levels of analysis: within-person, between persons, in interpersonal exchanges, in groups, and across the organization as a whole. Our model is differentiated from earlier characterizations of emotional labor in that we propose that the phenomenon begins with energy generation instead of energy depletion; and is neither a one-way nor a one-by-one service episode. We further proffer that the intra-psychic processes embedded in emotional labor represent a form of social self-regulation that impacts across multiple levels within service organizations. We conclude by discussing the implications and limitations of our model for emotional labor research.

This paper synthesizes the extant feedback literature, focusing on how feedback affects an auditor’s learning, performance, and motivation. Performance feedback is an important component in the auditing environment for ensuring quality control and for developing and coaching staff auditors. However, the literature on feedback in the audit environment is fragmented and limited making it difficult to assess its behavioral effects on auditors. This paper has three main objectives. The first is to review some of the influential research in psychology and management to identify key variables and issues that appear to be critical in the study of behavioral consequences of feedback in organizational settings. The second is to review performance feedback research specifically in auditing to identify the areas previously examined and synthesize the findings. The third is to suggest a variety of future research opportunities that may assist in developing an understanding and knowledge of the behavioral effects of feedback on auditors. The literature analysis has significant implications for audit research and practice. In particular, the analysis provides important insights into understanding who, how, and when performance feedback should be given to improve its effectiveness in the audit environment.

This study investigates the situations in which productive organizational energy (POE) and organizational performance increase through customer passion, that is, perceived customers’ affective commitment and customers’ positive word-of-mouth behavior. We integrate research on POE with research on customer influences on employees. Based on emotional contagion processes we develop hypotheses for the energizing influences of customers at the organizational level. We test the hypotheses using a dataset containing 495 board members and 8,299 employees of 152 organizations. The results show that customer passion is positively related to POE, which is in turn positively related to organizational performance. Furthermore, the findings indicate that the effect of customer passion on organizational performance through POE depends on top management team’s (TMT’s) customer orientation. By providing first insights into the linkages and contingencies of customer passion, POE, and organizational performance, this study puts forth a more holistic understanding of the energizing effect of customers on organizations.

This chapter utilizes a network perspective to show how the totality of one’s social connections impacts well-being by providing access to resources (e.g., information, feedback, and support) and placing limits on autonomy. We provide a brief review of basic network concepts and explain the importance of understanding how the networks in which leaders are embedded may enhance or diminish their well-being. Further, with this greater understanding, we describe how leaders can help promote the well-being of their employees. In particular, we focus on four key aspects of workplace networks that are likely to impact well-being: centrality, structural holes, embeddedness, and negative ties. We not only discuss practical implications for leaders’ well-being and the well-being of their employees, but also suggest directions for future research.
