Development communication expectations in occupational contexts: A Comparison of U.S. and foreign graduate students

This study focuses on the communication approaches used by experts in development. In line with recent “paradigm shift” issues, this study asks whether foreign and U.S. graduate students have inculcated alternative communication approaches instead of, or in addition to, the predominant “top to bottom” communication approach in their occupational communication roles. A total of 24 foreign and 23 U.S. graduate students from various departments at the University of Washington were asked to describe their expected communication with contact groups above, at the same and at lower status levels. All graduate students showed a marked tendency to exhibit “top to bottom” approaches with contacts of lower status and alternative communication approaches (i.e., bottom to top or interactive) only with peers. Few differences were found between U.S. and foreign, but those that were found were attributed to differing societal and occupational structures. Discussion focused on the lack of a coherent communication approach showing inculcation of more user oriented approaches suggested by the “paradigm shift.”     

Searching for patterns in the MeSH vocabulary

NLM revises its MeSH vocabulary annually to reflect changes in biomedical literature and the health sciences community. This study tested two hypotheses about NLM's MeSH vocabulary. The first is that new terms are added to MeSH when their broader terms have an increased number of postings. One examination compared the number of postings for the broader terms of new and existing terms in the current MEDLINE file; the other compared them over time. No significant statistical difference was found in either case. A second hypothesis--that there is a relationship between the patterns of MEDLINE indexing and searching and the organization of the MeSH tree structure--was tested by comparing the distribution of searched terms in the MeSH trees with the distribution of all terms. It was found that certain trees are searched more often than could be predicted by the overall term distribution, while others are searched less frequently than expected. In summary, (1) new terms cannot be predicted by the increase in postings of existing terms, and (2) searchers' and indexers' use of the terms' tree structure does not correlate with the terms' distribution in the MeSH trees.
