Knowledge plays a critical role in achieving organization strategic objectives and gaining competitive advantage; thus, knowledge like other organizational resources needs to be managed. However, knowledge management (KM) often lacks adequate infrastructure and necessary requirements that makes its implementation difficult and costly. It is argued that the first step to accommodate a KM strateg...

Although early-stage affective disorders are associated with both cognitive dysfunction and sleep-wake disruptions, relationships between these factors have not been specifically examined in young adults. Sleep and circadian rhythm disturbances in those with affective disorders are considerably heterogeneous, and may not relate to cognitive dysfunction in a simple linear fashion. This study aim...

OBJECTIVE Two measures of affect-affective attitude (AA) and anticipated affective reaction (AAR)-have frequently been used individually, but rarely simultaneously, in correlational studies predicting health behaviors. This research assessed their individual and combined impact in predicting intention and action for a range of health behaviors, controlling for theory of planned behavior (TPB) v...

To ensure learning, game-based learning environments must incorporate assessment mechanisms, e.g. Intelligent Tutoring Systems (ITSs). ITSs are focused on recognising and influencing the learner’s emotional or motivational states. This research focuses on designing and implementing an affective student model for intelligent gaming, which reasons about the learner’s emotional state from cognitiv...

The U.S. Army Reserve struggles with retention and faces difficulties with soldier turnover. The intent of the study was to assess key psychological variables such as optimism and hope to establish how those traits might impact soldiers' level of organizational commitment and turnover intention in the Army. The sample consisted of 124 U.S. soldiers selected from an Army Reserve unit in Houston,...

The ability of cognitive, affective, personality, and demographic variables to predict second-language acqui sition among college students was investigated. An all possible subsets regression analysis was used to compare the propor tion of variance in foreign-language achievement explained by each variable. The analysis revealed that variables from each of the 4 domains were important predictor...

Serotonin (5-HT) appears to modulate affective behaviours by providing a homeostatic threshold around which other transmitters respond. This general principle of activity should hold for other types of behaviour, including cognition, but has not been extensively examined. We hypothesized, based on past findings, that increased 5-HT would constrain prefrontally guided working memory functions th...
