Is there a relationship between burnout and objective performance? A critical review of 16 studies

Previous research has suggested that high levels of burnout lead to impaired functioning on the job. However, as this research has usually relied on self-reported performance, it is imperative to examine whether this association is also confirmed when using “objective” performance data (e.g., supervisor reports). This study reviewed previous research on the associations between burnout (exhaustion, depersonalization, and personal accomplishment) and various types of objective performance. A systematic literature search identified 16 studies dealing with the burnout-performance relationship. These studies showed the wide variety of approaches that are used to study burnout and objective performance. Using data from these 16 studies, a meta-analysis was conducted to obtain mean correlations. The meta-analytical correlations between exhaustion and in-role behaviour (based on five studies), organizational citizenship behaviour (OCB; five studies), and customer satisfaction (two studies) were -.22, -.19, and -.55, respectively, underlining the practical relevance of burnout research for organizational performance. The evidence for the relationships between depersonalization, personal accomplishment, and performance was inconclusive. Future research should focus on valid indicators of job performance, should more often employ longitudinal designs and large samples, and should consider the theoretical basis for the study expectations more extensively.

高等教育与我国地区经济发展关系的实证研究——从人力资本存量的角度

本文从人力资本存量的角度考察了2004年我国高等教育与地区经济发展之间的关系。研究发现:(1)高等教育与当地经济发展存在高度正相关,但地理位置因素也会影响到其强弱。(2)高等教育对中部地区经济增长的促进作用最明显,京津及东部沿海地区次之,西部地区最低。(3)总体来看,高等教育对经济增长贡献仍然偏低。因此,应进一步加大高等教育投入,提高其对经济增长贡献。     

Relationships between stressful work environments and bullying: Results of a large representative study

Abstract

This paper contributes to the relatively sparse knowledge about relationships between stressful work environments and bullying. Relationships between job stressors and leadership behaviour were analysed as possible predictors of bullying at work on the basis of the work environment hypothesis, which states that stressful and poorly organized work environments may give rise to conditions resulting in bullying. Analyses of a representative sample (n=2539) of the Norwegian workforce showed role conflict, interpersonal conflicts, and tyrannical and laissez-faire leadership behaviour to be strongly related to bullying, and that the strength of associations to a high degree differed for various measures of bullying. Support was found for an interactive relationship between decision authority and role conflict at different levels of laissez-faire leadership. Not only targets and bully/targets but also bystanders assessed their work environment more negatively than did non-involved employees, while perpetrators of bullying did not differ significantly from non-involved employees as regards their perception of the work environment. Hence, bullying is likely to prevail in stressful working environments characterized by high levels of interpersonal friction and destructive leadership styles. In addition, bullying is particularly prevalent in situations where the immediate supervisor avoids intervening in and managing such stressful situations.     

Modeling Imbalanced Economic Recovery Following a Natural Disaster Using Input‐Output Analysis

Input‐output analysis is frequently used in studies of large‐scale weather‐related (e.g., Hurricanes and flooding) disruption of a regional economy. The economy after a sudden catastrophe shows a multitude of imbalances with respect to demand and production and may take months or years to recover. However, there is no consensus about how the economy recovers. This article presents a theoretical route map for imbalanced economic recovery called dynamic inequalities. Subsequently, it is applied to a hypothetical postdisaster economic scenario of flooding in London around the year 2020 to assess the influence of future shocks to a regional economy and suggest adaptation measures. Economic projections are produced by a macro econometric model and used as baseline conditions. The results suggest that London's economy would recover over approximately 70 months by applying a proportional rationing scheme under the assumption of initial 50% labor loss (with full recovery in six months), 40% initial loss to service sectors, and 10–30% initial loss to other sectors. The results also suggest that imbalance will be the norm during the postdisaster period of economic recovery even though balance may occur temporarily. Model sensitivity analysis suggests that a proportional rationing scheme may be an effective strategy to apply during postdisaster economic reconstruction, and that policies in transportation recovery and in health care are essential for effective postdisaster economic recovery.     

The impact of international experience on cultural intelligence: an application of contact theory in a structured short-term programme

The objective of this study is to examine the impact of a short-term international experience, which is designed to address the conditions outlined in Allport’s (Allport, G.W. 1954. The Nature of Prejudice. New York: Perseus Book Group) contact hypothesis, on each of the four factors which make up cultural intelligence (CQ). A sample of 135 university students was broken up into test and control groups. The results for the test group suggest that the short-term experience ranging from 7 to 12 days within a structured study abroad service programme, including modest pre-trip preparation, found a significant increase in each of the four factors of CQ. At the same time, there was no significant change in the control group. Implications for human research development research and practice as well as limitations and suggested areas for future research are discussed.     

Testing Hypotheses About the Number of Factors in Large Factor Models

In this paper we study high‐dimensional time series that have the generalized dynamic factor structure. We develop a test of the null of k₀ factors against the alternative that the number of factors is larger than k₀ but no larger than k₁>k₀. Our test statistic equals max_{k0<k k1}(γ_k−γ_k+1)(γ_k+1−γ_k+2), where γ_i is the ith largest eigenvalue of the smoothed periodogram estimate of the spectral density matrix of data at a prespecified frequency. We describe the asymptotic distribution of the statistic, as the dimensionality and the number of observations rise, as a function of the Tracy–Widom distribution and tabulate the critical values of the test. As an application, we test different hypotheses about the number of dynamic factors in macroeconomic time series and about the number of dynamic factors driving excess stock returns.     

Improving Weight of Evidence Approaches to Chemical Evaluations

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation.
