Creating organizational citizens: How and when supervisor- versus peer-led role interventions change organizational citizenship behavior.

We generate and test new theory on how organizations can use role interventions to increase employees' organizational citizenship behavior (OCB) such as helping and voice. In particular, we examine how interventions that employ supervisors and peers as change agents can independently and jointly motivate employees to engage in OCB by encouraging them to view their work roles more broadly. We propose that the effects of these interventions become apparent over two distinct temporal phases of change.

When daily planning improves employee performance: The importance of planning type, engagement, and interruptions.

Does planning for a particular workday help employees perform better than on other days they fail to plan? We investigate this question by identifying 2 distinct types of daily work planning to explain why and when planning improves employees' daily performance. The first type is time management planning (TMP)-creating task lists, prioritizing tasks, and determining how and when to perform them. We propose that TMP enhances employees' performance by increasing their work engagement, but that these positive effects are weakened when employees face many interruptions in their day.

Mapping the global potential for marine aquaculture.

Marine aquaculture presents an opportunity for increasing seafood production in the face of growing demand for marine protein and limited scope for expanding wild fishery harvests. However, the global capacity for increased aquaculture production from the ocean and the relative productivity potential across countries are unknown. Here, we map the biological production potential for marine aquaculture across the globe using an innovative approach that draws from physiology, allometry and growth theory.

Regulating and facilitating: the role of emotional intelligence in maintaining and using positive affect for creativity.

Although past research has identified the effects of emotional intelligence on numerous employee outcomes, the relationship between emotional intelligence and creativity has not been well established. We draw upon affective information processing theory to explain how two facets of emotional intelligence-emotion regulation and emotion facilitation-shape employee creativity. Specifically, we propose that emotion regulation ability enables employees to maintain higher positive affect (PA) when faced with unique knowledge processing requirements, while emotion facilitation ability enables employees to use their PA to enhance their creativity.

Doing right versus getting ahead: the effects of duty and achievement orientations on employees' voice.

Using role theory as the overarching framework, we propose that employees' voice has contrasting relationships with the traits of duty orientation, or employees' dispositional sense of moral and ethical obligation at the workplace, and achievement orientation, or the extent of their ingrained personal ambition to get ahead professionally. Using data from 262 employees and their managers, we demonstrate that duty and achievement orientations are, respectively, positively and negatively related to voice through their impact on voice role conceptualization or the extent to which employees consider voice as part of their personal responsibility at work. Further, we delineate how employees' beliefs about their efficacy to engage in voice and judgments about psychological safety in the organization can moderate these relationships.

Marine debris accumulation in the Northwestern Hawaiian Islands: an examination of rates and processes.

Large amounts of derelict fishing gear accumulate and cause damage to shallow coral reefs of the Northwestern Hawaiian Islands (NWHI). To facilitate maintenance of reefs cleaned during 1996-2005 removal efforts, we identify likely high-density debris areas by assessing reef characteristics (depth, benthic habitat type, and energy regime) that influence sub-regional debris accumulation. Previously cleaned backreef and lagoonal reefs at two NWHI locations were resurveyed for accumulated debris using two survey methods.
