Collective density variables rho (k) have proved to be useful tools in the study of many-body problems in a variety of fields that are concerned with structural and kinematic phenomena. In spite of their broad applicability, mathematical understanding of collective density variables remains an underexplored subject. In this paper, we examine features associated with collective density variables...

the present research aims to develop a model and assess changeability grounds in public organizations. the statistical population includes public organizations in the cities of lamerd and mohr. the research includes three fundamental stages, each of which tries to answer a key question. to devise a proper model, we initially study the theoretical literature of change management and the resistan...

Scale developers often provide evidence of content validity by computing a content validity index (CVI), using ratings of item relevance by content experts. We analyzed how nurse researchers have defined and calculated the CVI, and found considerable consistency for item-level CVIs (I-CVIs). However, there are two alternative, but unacknowledged, methods of computing the scale-level index (S-CV...

Coastal zones are considered to be highly vulnerable the effects of climate change, such as erosion, flooding, and storms, including sea level rise (SLR). The rising levels endanger several nations, Indonesia, it potentially affects coastal population natural environment. Quantification is needed determine degree vulnerability experienced by a coast since measuring fundamental phase towards eff...
