This paper is in memory of Esther Thelen, who passed away while President of the Society for Research in Child Development. A survey of Esther Thelen's career reveals a trajectory from early work on simple movements like stepping, to the study of goal-directed reaching, to work on the embodiment of cognition, and, ultimately, to a grand theory of development--dynamic systems theory. Four central concepts emerged during her career: (1) a new emphasis on time; (2) the proposal that behavior is softly assembled from the interaction of multiple subsystems; (3) the embodiment of perception, action, and cognition; and (4) a new respect for individuality. Esther Thelen communicated these ideas to scientists and practitioners alike, so the ultimate benefactors of her work were children.  相似文献

Forgeries of Fossils in “Amber”: History,Identification and Case Studies     

David A. Grimaldi  Alexander Shedrinsky  Andrew Ross  Norbert S. Baer 《Curator: The Museum Journal》1994,37(4):251-274

The appeal of ancient fossilized tree resin, or amber, has made pieces with animal and plant inclusions particularly prized. Unfortunately, amber forgeries are more convincingly and routinely made than most other kinds of fossils, by embedding organisms in natural resins (e.g., copal) or synthetic resins (especially polyester) or by filling a carved niche in a natural piece of amber with resin and a modern inclusion. The confusion of organisms in copal (forged and natural) for ones in amber has a long history. Reviewed here are simple tests for discerning forgeries and natural inclusions in both substances. We discuss an old but sophisticated technique for crafting amber forgeries from authentic amber and present several new examples from old collections in two large museum collections. Also discussed is the widespread use of polyester resin forgeries in the Dominican Republic and Mexico.  相似文献   

Sales Teams or Salespersons: Performance Implications for Embracing Individualistic and Collectivistic Cultural Values in a Global Marketplace     

Lawrence E. Ross  Katie P. Desiderio  Michael Knudstrup  Michael G. Frino 《Performance Improvement Quarterly》2014,26(4):53-73

Identifying antecedents of salesperson performance is a long‐standing objective in the sales management research field. The purpose of this article is to outline how the practical understanding of, and the willingness to embrace, sales employees' cultural value‐systems adds value while considering performance drivers, individualistic versus collectivistic values, and performance outcomes. The cultural dimensions under consideration, individualism and collectivism, cannot be approached as a dichotomy. As is the case for all cultural dimensions, they represent a continuum and not absolutes. In this study, the work preferences and predispositions of participants were compared using an international data set. Respondents were culturally classified based on research (i.e., Americans and Australians as individualists and Japanese and South Koreans as collectivists). Specifically, it was found that individualists were less attached to their current work situation; collectivists indicated less work/family conflict; and individualists valued independent work more while collectivists valued deciding work time. This is important because of the need to understand how to effectively connect with the values of people to encourage positive performance outcomes. The reality is that value holds differing degrees of emphasis; the performance formula is the theoretical framework to guide this research. The implications of the results for sales management professionals are discussed.  相似文献
