Regulatory focus as a mediator in goal orientation and performance relationships

Chosen goals influence the outcomes a person achieves as well as the behaviors performed to achieve those outcomes. In this study, we propose that three forms of goal orientation: learning, performance‐prove, and performance‐avoid, (VandeWalle, 1997 ) relate to performance, with learning and performance‐prove relating to performance through regulatory foci of prevention and promotion, respectively. Regulatory focus, a type of self‐regulation, entails the implementation of specific strategies in pursuit of goals and thus gives us insight to how a person pursues a chosen goal. In a combination of laboratory and field studies, we examine the role of regulatory focus as a mediator between goal orientation and task performance. We find evidence that regulatory focus strategies differentially mediate the goal orientation/task performance relationship. Theoretical ramifications for these relationships, as well as practical implications, are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Integrating attachment style,vigor at work,and extra‐role performance

This paper presents and tests a model of the impact of secure and insecure attachment styles (secure, counterdependent, and overdependent) on citizenship behavior and workplace deviance behavior through vigor at work. Employees who exhibit secure attachment styles are proposed to exhibit more vigor at work because of more effective use of physical, emotional, and cognitive resources which translates into increased organizational citizenship behaviors (OCBs) and decreased deviance. Insecurely attached employees are hypothesized to exhibit the opposite pattern. In a sample of 331 repair generalists in a large building facilities and maintenance organization, results indicate that attachment styles indirectly predicted OCBs and deviance through vigor. Implications of these results for attachment style, vigor at work, OCBs, and deviance are discussed. Copyright © 2010 John Wiley & Sons, Ltd.

Posttreatment Tree Mortality After Forest Ecological Restoration,Arizona, United States

Pine–oak forests are of high ecological importance worldwide, but many are threatened by uncharacteristically severe wildfire. Forest restoration treatments, including the reintroduction of a surface fire regime, are intended to decrease fire hazard and emulate historic ecosystem structure and function. Restoration has recently received much management attention and short-term study, but little is known about longer-term ecosystem responses. We remeasured a replicated experimental restoration site in the southwestern United States 5 years after treatments. Basal area, tree density, and canopy cover decreased in the treated units at a faster rate than in controls. Delayed mortality, not evident right after treatment, decreased density modestly (13% in treated units and 10% in controls) but disproportionately affected large trees (“large” ponderosa pines were those with diameter at breast height [dbh] ≥37.5 cm; other species dbh ≥20 cm). In treated units, 10.9 large trees ha^–1 died, whereas 6.2 trees ha^–1 died in control units. Compared with reference conditions, the experimental blocks remained higher in pine density and, in three of the four blocks, in basal area. Pine trees grew significantly faster in treated units than in controls, enough to reach the reference level of basal area in 6 years. Although mortality of large trees is a concern, the treated units have vigorous growth and low density, indicating that they will be relatively resistant to future drought and fire events. Similar treatments may be beneficial in many areas of the United States and in related pine-oak ecosystems elsewhere.
