Movement patterns of winter flounder (Pseudopleuronectes americanus) in the southern Gulf of Maine: observations with the use of passive acoustic telemetry

Despite its recreational and commercial importance, the movement patterns and spawning habitats of winter flounder (Pseudopleuronectes americanus) in the Gulf of Maine are poorly understood. To address these uncertainties, 72 adult winter flounder (27–48 cm) were fitted with acoustic transmitters and tracked by passive telemetry in the southern Gulf of Maine between 2007 and 2009. Two sympatric contingents of adult winter flounder were observed, which exhibited divergent spawning migrations. One contingent remained in coastal waters during the spawning season, while a smaller contingent of winter flounder was observed migrating to estuarine habitats. Estuarine residence times were highly variable, and ranged from 2 to 91 days (mean=28 days). Flounder were nearly absent from the estuary during the fall and winter months and were most abundant in the estuary from late spring to early summer. The observed seasonal movements appeared to be strongly related to water temperature. This is the first study to investigate the seasonal distribution, migration, and spawning behavior of adult winter flounder in the Gulf of Maine by using passive acoustic telemetry. This approach offered valuable insight into the life history of this species in nearshore and estuarine habitats and improved the information available for the conservation and management of this species

Leadership in the locker room: How the intensity of leaders' unpleasant affective displays shapes team performance.

Research has documented conflicting evidence about the relationship between a leader's unpleasant affective displays and team performance. Drawing on the dual threshold model of anger, we propose a novel explanation for this paradox such that the positive relationship between leaders' unpleasant affect and team performance turns negative at high levels of intensity. We examined our hypothesis in a multilevel field study of 304 halftime locker room speeches involving 23 high school and college basketball teams and a follow-up experiment. Our results show support for the prediction and suggest that the curvilinear effect of leaders' unpleasant affective displays may be explained by team members' redirection of attention and approach, which is positively associated with team members' effort at moderate levels of leader unpleasantness but leads to lower effort at high and low levels of leader unpleasantness. We discuss the theoretical contributions for scholarship on leadership, emotions as social information theory, and practical implications of the results.

Jubah and Nashoba: An Artful History

This creative dissertation unites art and history by writing a play using extensive historical research. The main body of work focuses on events surrounding the Natchez Revolt of 1729. The Natchez nation and colonial Louisianans attempted to accommodate each other by reaching a middle ground. Nonetheless, incivility culminated in a massacre at Fort Rosalie. The Natchez experienced profound sociopolitical changes that resulted in a downgrade of female power. North American history asserts many female chiefs interacted with colonial male leaders. Even so, female chiefs have remained at the margins of history. This creative work focuses on the hidden history behind the subjugation of one female chief named Tattooed Arm
