Sharpening the Search Saw: Lessons from Expert Searchers

Many students consider themselves to be proficient searchers and yet are disappointed or frustrated when faced with the task of locating relevant scholarly articles for a literature review. This bleak experience is common among higher education students, even for those in library and information science programs who have heightened appreciation for information resources and yet may settle for “good enough Googling” (Plosker, 2004, p. 34). This is in large part due to reliance on web search engines that have evolved relevance ranking into a vastly intelligent business, one in which we are both its customers and product (Vaidhyanathan, 2011). Google’s Hummingbird nest of search algorithms (Sullivan, 2013) provides quick and targeted hits, yet it can trigger blinders-on trust in first-page results. Concern for student search practices ranges from this permissive trust all the way to lost ability to recall facts and formulate questions (Abilock, 2015), lack of confidence in one’s own knowledge (Carr, 2010), and increased dependence on single search boxes that encourage stream-of-consciousness user input (Tucker, 2013); indeed, students may be high in tech savvy but lacking the critical thinking skills needed for information research tasks (Katz, 2007). Students have come to rely on web search engine intelligence—and it is inarguably colossal—to such an extent that they may fail to formulate a question before charging forward to search for its answer. “Google is known as a search engine, yet there is barely any searching involved anymore. The gap between a question crystallizing in your mind and an answer appearing at the top of your screen is shrinking all the time. As a consequence, our ability to ask questions is atrophying” (Leslie, 2015, para. 4). Highly accomplished students often lament their lack of skills for higher-level searching that calls for formulating pointed questions when struggling to develop a solid literature review. In addition, many are unaware that search results are filtered based on previous searches, location, and other factors extracted from personal search patterns by the search engine. Two students working side by side and entering the same search terms may receive quite different results on Google, yet the extent to which this ‘filter bubble’ (Pariser, 2011) is personalizing their search results is difficult to assess and to overcome. Just as important, it can be impossible to know what a search might be missing: how to know what’s not there? This portrayal of the information landscape may appear gloomy but, in fact, it could not be a more inspiring environment in which to do research, to find connections in ideas, and to benefit from and generate new ideas. A few lessons from expert searchers, focused on critical concepts and search practices, can sharpen a student’s search saw and move the proficient student-researcher, desiring more relevant and comprehensive search results, into a trajectory toward search expertise. For the lessons involved in this journey, the focus is on two areas: first, the critical concepts— called threshold concepts (Meyer & Land, 2003)— found to be necessary for developing search expertise (Tucker et al., 2014); and, second, four strategic areas within search that can have significant and immediate impact on improving search results for research literature. The latter are grounded in the threshold concepts and positioned for application to literature reviews for graduate student studies

Relationship maintenance, democratic decision making, and decision agreement

Thesis (M.A.) University of Alaska Fairbanks, 2012Relationship maintenance uses different strategies to maintain a relationship at the desired level of intimacy. Democratic decision making is a practice through which each individual has equal rights in the decision-making process. The present study investigated connections among two areas of research. In particular, this study examined the correlations among relationship maintenance behaviors, democratic decision making, and decision agreement. Both hypotheses in the study were supported, which suggests relationship maintenance promotes democratic decision making, which in turn promotes decision agreement

On Becoming A Psychiatrist: A Resident\u27s Perspective

Developing an identity as a psychiatrist is a process which has been seen by many to span an individual\u27s career; from the first decision of choice of a career, through residency training and beyond, into the years of practice. As part of a Residents\u27 Day Paper, psychiatrists in the Oklahoma City area were surveyed in order to look at their perceptions of the growth of their professional identities. Despite the limitations of a small sample population, limited to one metropolitan area, some interesting common patterns emerged: the psychiatrists surveyed had diverse educational and cultural back grounds, similar practical and unconscious motivations for entering the field, influential role models, and specific developmental tasks mastered during and after training

Solutions for Neutral for Axi-Dilaton Gravity in 4-Dimensions

We examine a 1 parameter class of actions describing the gravitational interaction between a pair of scalar fields and Einsteinian gravitation. When the parameter is positive the theory corresponds to an axi-dilatonic sector of low energy string theory. We exploit an SL(2,R) symmetry of the theory to construct a family of electromagnetically neutral solutions with non-zero axion and dilaton charge from solutions of the Brans-Dicke theory. We also comment on solutions to the theory with negative coupling parameter.Comment: 7 pages Plain Tex (No Figures), Letter to Editor, Classical and Quantum Gravit
