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...

In this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. For this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. Then, by using the Monte-Carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

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...

Data on the perception of the relationships of friendship and work...

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...

BACKGROUND An exclusive focus on individual or family coping strategies may be inadequate for people whose major point of concern may be collective healing on a more communal level. METHODS To our knowledge, the current study is the first to make use of ethnographic fieldwork methods to investigate this type of coping as a process in a natural setting over time. Participant observation was em...
