Influences on the architecture of human resource management in nonprofit organizations: An analytical framework
Human resource management (HRM) plays an important role in providing better management for nonprofit organizations (NPOs). Yet little is known about what influences their human resource practices. After discussing how the strategic and human-resource-based theoretical approaches are appropriate for analyzing HRM in NPOs, the authors explore the current nonprofit literature to identify the specific characteristics of strategic orientations and human resources in NPOs. As a result, the authors propose an analytical framework that is differentiated into four HRM types. This framework enables a better understanding of the relationship between the specific characteristics of NPOs and the architecture of HRM. © 2010 SAGE Publications
Ecological Entomology
International audienceAnts are widespread in tropical rainforests, including in the canopy where territorially dominant arboreal species represent the main part of the arthropod biomass.By mapping the territories of dominant arboreal ant species and using a null model analysis and a pairwise approach this study was able to show the presence of an ant mosaic on the upper canopy of a primary Neotropical rainforest (c. 1 ha sampled; 157 tall trees from 28 families). Although Neotropical rainforest canopies are frequently irregular, with tree crowns at different heights breaking the continuity of the territories of dominant ants, the latter are preserved via underground galleries or trails laid on the ground.The distribution of the trees influences the structure of the ant mosaic, something related to the attractiveness of tree taxa for certain arboreal ant species rather than others. Small-scale natural disturbances, most likely strong winds in the area studied (presence of canopy gaps), play a role by favouring the presence of two ant species typical of secondary formations: Camponotus femoratus and Crematogaster levior, which live in parabiosis (i.e. share territories and nests but lodge in different cavities) and build conspicuous ant gardens. In addition, pioneer Cecropia myrmecophytic trees were recorded
