Work hours,social value of leisure and globalisation

We examine how openness interacts with the coordination of consumption–leisure decisions in determining the equilibrium working hours and wage rate when there are leisure externalities (e.g., due to social interactions). The latter are modelled by allowing a worker's marginal utility of leisure to be increasing in the leisure time taken by other workers. Coordination takes the form of internalising the leisure externality and other relevant constraints (e.g., labour demand). The extent of openness is measured by the degree of capital mobility. We find that: coordination lowers equilibrium work hours and raises the wage rate; there is a U-shaped (inverse-U-shaped) relationship between work hours (wages) and the degree of coordination; coordination is welfare improving; and, the gap between the coordinated and uncoordinated work hours (and the corresponding wage rates) is affected by the extent and nature of openness.     

Species richness in urban parks and its drivers: A review of empirical evidence

There is growing recognition of urban areas as hosts for innovative ways to conserve and promote biodiversity. Parks, as one specific type of urban green space, constitute particularly important biodiversity hotspots in the cityscape. We reviewed empirical findings on the species richness in urban parks across all species groups that have been studied. The aim was to assess and discuss the overall species richness of urban parks, its community attributes and drivers. Search and subsequent selection process resulted in 62 papers from 25 different countries. For all examined species groups, the findings consistently show that parks are among the most species rich types of urban green spaces, but also that exotics constitute large shares, especially of plant species. Key ecological theories like the gradient approach and the island habitat ecological theory, and fundamental ecological relationships such as the species-area relationship are valid despite the manipulated ‘nature’ of parks and the surrounding urban matrix. Most studies surveyed large number of parks and applied ‘multi-scale’ approaches in tests of confounding variables, providing methodological strength. While matrix effects are consistently found to affect species richness negatively, the diversity of habitats and microhabitat heterogeneity contained in urban parks appears as the most decisive factor for the overall species richness. However, a constraint of research to date is the limitation of individual studies to one or a few species groups, rarely bridging between flora and fauna. Adopting ‘multi-species group’ approaches in future research is needed to further advance the understanding of the overall biodiversity of urban parks, and its drivers.     

Empowered and self-managing users in methadone treatment?

Empowerment is a keyword in treatment. Users should have the means and possibilities to influence their treatment and become self-managing. Drawing on ethnographic fieldwork in a Danish methadone treatment project, we find that the practices of users and staff are often not carried out in accordance with governmental intentions. We identify a gap between the official notions of treatment and practices. We analyse the notions and practices of empowerment by applying two analytical perspectives. First, we apply a constructionist perspective in which empowerment is analysed as wanting to set users ‘free’ but also as ways to govern. We elaborate the analysis by applying a more practice-oriented focus. Drawing on this perspective, we analyse the ways in which staff and users constantly produce, construct and negotiate institutional practices that differ from the governmental intentions for treatment.     

The impact of a workplace terrorist attack on employees' perceptions of leadership: A longitudinal study from pre- to postdisaster

A terrorist attack targeting a workplace represents an organizational crisis that requires the leaders to manage emerging threats. The changing roles and expectations of the leaders are reflected in the employees' perceptions of them over time. The purpose of this study was to determine whether the 2011 Oslo bombing attack affected the targeted employees' perceptions of the leadership behaviors of their immediate superiors or the organizational managers' interest in the health and well-being of their workers. Ministerial employees (n ≈ 180) completed questionnaires on fair, empowering, and supportive leadership, in addition to human resource primacy, on two occasions several years prior to the terrorist attack. Assessments were then repeated one, two, and three years after the attack. Changes in the course of perceived leadership from predisaster to postdisaster were examined using bootstrapped t-tests and latent growth curve models. Furthermore, the general course of perceived leadership was compared with a nonexposed control sample of matched employees. Results showed that employees with high levels of posttraumatic stress perceived their immediate leader to be less supportive. However, overall perceptions of leadership were remarkably stable, which suggests that the effects of critical incidents on perceptions of leadership may be negligible.     

Workplace resources to improve both employee well-being and performance: A systematic review and meta-analysis

Organisations are becoming increasingly aware of the importance of employees in gaining and maintaining competitive advantage. The happy worker–productive worker thesis suggests that workers who experience high levels of well-being also perform well and vice versa; however, organisations need to know how to ensure such happy and productive workers. The present review and meta-analysis identifies workplace resources at the individual, the group, the leader, and the organisational levels that are related to both employee well-being and organisational performance. We examine which types of resources are most important in predicting both employee well-being and performance. We identified 84 quantitative studies published in print and online from 2003 to November 2015. Resources at either of the four levels were related to both employee well-being and performance. We found no significant differences in employee well-being and organisational performance between the four levels of workplace resources, suggesting that interventions may focus on any of these levels. Cross-sectional studies showed stronger relationships with well-being and performance than longitudinal studies. Studies using objective performance ratings provided weaker relationships between resources and performance than self-rated and leader/third-party-rated studies.     

The Prevalence of Destructive Leadership Behaviour

This study investigates the prevalence of the four types of destructive leadership behaviour in the destructive and constructive leadership behaviour model, in a representative sample of the Norwegian workforce. The study employs two estimation methods: the operational classification method (OCM) and latent class cluster (LCC) analysis. The total prevalence of destructive leadership behaviour varied from 33.5% (OCM) to 61% (LCC), indicating that destructive leadership is not an anomaly. Destructive leadership comes in many shapes and forms, with passive forms prevailing over more active ones. The results showed that laissez‐faire leadership behaviour was the most prevalent destructive leadership behaviour, followed by supportive–disloyal leadership and derailed leadership, while tyrannical leadership behaviour was the least prevalent destructive leadership behaviour. Furthermore, many leaders display constructive as well as destructive behaviours, indicating that leadership is not either constructive or destructive. The study contributes to a broader theoretical perspective on what must be seen as typical behaviour among leaders.     

Top Management Team Diversity: A Review of Theories and Methodologies

This paper reviews empirical research on top management team (TMT) diversity. A number of scholars have concluded that upper echelons findings, in particular in terms of the consequences of TMT heterogeneity, have been inconclusive. This review conducts an in‐depth analysis of conceptual and methodological issues related to upper echelons diversity studies and offers some directions for future research. Sixty journal articles, published in ten top international journals over a 22‐year period (1984–2005), were analyzed. The results suggest that upper echelons research is increasingly multidisciplinary in nature; however, in‐depth inquiries into the antecedents of TMT composition and the multilevel contextual influences on the implications of TMT heterogeneity are still needed. This review finds that clarity about level of analysis, both theoretically and empirically, remains an important issue in the field and thus a multilevel approach is strongly encouraged. Moreover, the complexity of diversity as a theoretical construct needs to be acknowledged and operationalized accordingly in upper echelons studies.     

The Use of Telematics Devices to Improve Automobile Insurance Rates

Most automobile insurance databases contain a large number of policyholders with zero claims. This high frequency of zeros may reflect the fact that some insureds make little use of their vehicle, or that they do not wish to make a claim for small accidents in order to avoid an increase in their premium, but it might also be because of good driving. We analyze information on exposure to risk and driving habits using telematics data from a pay‐as‐you‐drive sample of insureds. We include distance traveled per year as part of an offset in a zero‐inflated Poisson model to predict the excess of zeros. We show the existence of a learning effect for large values of distance traveled, so that longer driving should result in higher premiums, but there should be a discount for drivers who accumulate longer distances over time due to the increased proportion of zero claims. We confirm that speed limit violations and driving in urban areas increase the expected number of accident claims. We discuss how telematics information can be used to design better insurance and to improve traffic safety.     

Assessing Engineering Resilience for Systems with Multiple Performance Measures

Recently, efforts to model and assess a system's resilience to disruptions due to environmental and adversarial threats have increased substantially. Researchers have investigated resilience in many disciplines, including sociology, psychology, computer networks, and engineering systems, to name a few. When assessing engineering system resilience, the resilience assessment typically considers a single performance measure, a disruption, a loss of performance, the time required to recover, or a combination of these elements. We define and use a resilient engineered system definition that separates system resilience into platform and mission resilience. Most complex systems have multiple performance measures; this research proposes using multiple objective decision analysis to assess system resilience for systems with multiple performance measures using two distinct methods. The first method quantifies platform resilience and includes resilience and other “ilities” directly in the value hierarchy, while the second method quantifies mission resilience and uses the “ilities” in the calculation of the expected mission performance for every performance measure in the value hierarchy. We illustrate the mission resilience method using a transportation systems‐of‐systems network with varying levels of resilience due to the level of connectivity and autonomy of the vehicles and platform resilience by using a notional military example. Our analysis found that it is necessary to quantify performance in context with specific mission(s) and scenario(s) under specific threat(s) and then use modeling and simulation to help determine the resilience of a system for a given set of conditions. The example demonstrates how incorporating system mission resilience can improve performance for some performance measures while negatively affecting others.
