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...
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...
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...
