Several successful partitioning models and methods have been proposed used for computational load balancing of irregularly sparse applications in a distributed-memory setting. However, the literature lacks that encode both data balancing. In this article, we try to close gap by proposing two hypergraph (HP) which simultaneously Both utilize two-constraint formulation, where first constraint enc...

It is arguable that the instinct for survival in animal species has evolved due to the evolutionary elimination of those individuals who did not have enough inclination nor desire to cluster in a team. Thus, the roots of ethical conduct in its many facets in today’s world, may be sought in this very primeval concern for the society that enabled communities, rather than individuals, to survive i...

The swift growth of Internet has boosted the use of Web based services and in some practical cases has led to overwhelming request bursts to servers. Relational database queries, image storage/retrieval and other new types of application transactions have become increasingly popular. Their coexistence in commercial parallel and distributed systems have generated some uniquely new loading proble...

Despite ongoing concern about substance use during adolescence, very little is known about alcohol and drug use among teens living in affluent social settings. In this longitudinal study, cluster analysis was used to characterize patterns of substance use and change in other dimensions of psychosocial adjustment within a cohort of 292 high school students (54% girls) living in an affluent, subu...

Research on humor in organizations has rarely considered the social context in which humor occurs. One such social setting that most of us experience on a daily basis concerns the team context. Building on recent theorizing about the humor-performance link in teams, this study seeks to increase our understanding of the function and effects of humor in team interaction settings. We examined beha...

BACKGROUND Cognitive mapping is a participatory research methodology that documents, in visual form, a construct of the local environment in which people live and work. We adapted this method to provide detailed data about study locales to inform recruitment and retention strategies for HIV prevention community based clinical trials. METHODS Four cognitive mapping studies were undertaken betw...

We investigated how positive affectivity influences people's perception of the pat terns of social relationships around them. Positive affectivity was measured as trait positive affect. The outcome variable was accuracy in the perception of informal patterns of social interaction in a group (i.e., the group's network structure). Data on the perception of the relationships of friendship and work...

The words we use matter. The concept of a social norm exists in many social and behavioral science disciplines and research traditions (1). Because the general term “social norm” is a hypernym, an explicit definition is crucial to discussions of its place and usefulness in solving complex social–environmental issues (cf. ref. 2). In their discussion of incentives, Lubchenco et al. (3) suggest t...
