From expatriates' information needs to information management in the expatriation cycle

Andre, M, Barrulas, M J January 2006 (has links)
This study is aimed at to identify and to understand the role of information in what concerns the mobility process of top executives, helping organisations to make the most of their expatriatesâ experiences. The methodological approach chosen was the case study, carried out in an economic group of the Portuguese financial sector with several business operations abroad. Several data collection methods were used, including a questionnaire survey, in-depth interviews and in loco interaction with the expatriates in three different countries. Based on the analysis of expatriatesâ information needs, a typology of information throughout the complete cycle is described and two critical moments are identified. These moments correspond to transitions of expatriatesâ informational spaces: first the moment of arrival to the host country and second, when they return to their home country. The incorporation of expatriatesâ information in the organizational information system, across the various phases of the expatriation cycle, is summarized.

The New Context for Bibliographic Control In the New Millennium

Lynch, Clifford January 2000 (has links)
Information finding is changing in a world of digital information and associated search systems, with particular focus on methods of locating information that are distinct from, but complementary to, established practices of bibliographic description. A full understanding of these developments is essential in re-thinking bibliographic control in the new millennium, because they fundamentally change the roles and importance of bibliographic metadata in information discovery processes. There are three major approaches to finding information: through bibliographic surrogates, that represent an intellectual description of aspects and attributes of a work; through computational, content-based techniques that compare queries to parts of the actual works themselves; and through social processes that consider works in relationship to the user and his or her characteristics and history, to other works, and also to the behavior of other communities of users.

Usability evaluation of an NHS library web site

Ebenezer, Catherine 09 1900 (has links)
Objectives: To carry out a usability evaluation of the recently launched South London and Maudsley NHS Trust library website. Methods: A variety of standard methodologies were employed; content and design evaluation of selected comparable sites; focus groups; a questionnaire survey of library and Web development staff; heuristic evaluation; observation testing; card sorting/cluster analysis, and label intuitiveness/category membership testing. All participants were staff of or providers of services to the trust. Demographic information was recorded for each participant. Results: Test participants' overall responses to the site were enthusiastic and favourable, indicating the scope and and content of the site to be broadly appropriate to the user group. Testers made numerous suggestions for new content. Usability problems were discovered in two main areas: in the organisation of the site, and in the terminology used to refer to information services and sources. Based on test results, proposals for a revised menu structure, improved accessibility, and changes to the terminology used within the site are presented. Conclusion: Usability evaluation methods, appropriately scaled, can be advantageously applied to NHS library web sites by an individual web editor working alone.

Echo Chambers or Windows on the World? Partisan Selective Exposure and the Online News Environment

Garrett, Kelly 12 1900 (has links)
How will people use the Internet and other emerging information and communication technologies (ICTs) to shape their exposure to political information? Will Internet users be inclined to fashion an information environment that reflects their own political predispositions, or will they continue to encounter a range of perspectives online? In this talk Garrett addresses these questions using two interconnected research projects. The first project uses nationally representative survey data to examine how contemporary use of the Internet is influencing citizens' overall exposure to political information. The second project focuses on individual choices about exposure to news items in an online environment that affords enhanced control over partisanship. Taken together, these projects clarify the contemporary dynamic of selective political exposure, providing evidence about citizens' underlying preferences regarding political information. The results suggest that individuals' preference for support and their aversion to challenge are different. People (1) seek out sources that support their viewpoints; (2) are interested in news items with which they agree; and (3) use online sources to increase their repertoire of opinion-supporting arguments. They do not, however, systematically exclude exposure to other viewpoints. Ultimately, this research suggests that individuals value awareness of other perspectives, while simultaneously wanting to limit their contact with them.

Synergies Sparked: A Research Agenda for Practicing Professionals

Coleman, Anita Sundaram 11 1900 (has links)
This is a presentation (of 50 slides) at the University of California, Irvine sponsored by the Libraries' Department of Education and Outreach and by the LAUC-I (Librarians Association of the University of California, Irvine) Professional Development Committee. The title is picking up on the 2005 ASIS&T Annual Conference theme of Sparking Synergies: Bringing Research and Practice Together. Coleman discusses her research agenda which spans both sides of the information coin - she tries to examine representations of information and information usage in a unified program of inquiry. The research goal is to expand and integrate knowledge about uses and users in the organization of digital information and libraries. Using selected projects over the last 5 years as examples, Coleman identifies some ways to design, conduct, and manage doable research projects while also meeting the day-to-day demands of being a practicing professional. The focus is on the development of a cohesive research agenda (sustainable information behaviors), one that exemplifies and synchronizes with the values and challenges of practice, besides improving the quality of LIS research.

The Use of Dynamic Contexts to Improve Casual Internet Searching

Leroy, Gondy, Lally, Ann M., Chen, Hsinchun 07 1900 (has links)
Artificial Intelligence Lab, Department of MIS, University of Arizona / Research has shown that most usersâ online information searches are suboptimal. Query optimization based on a relevance feedback or genetic algorithm using dynamic query contexts can help casual users search the Internet. These algorithms can draw on implicit user feedback based on the surrounding links and text in a search engine result set to expand user queries with a variable number of keywords in two manners. Positive expansion adds terms to a userâ s keywords with a Boolean â and,â negative expansion adds terms to the userâ s keywords with a Boolean â not.â Each algorithm was examined for three user groups, high, middle, and low achievers, who were classified according to their overall performance. The interactions of users with different levels of expertise with different expansion types or algorithms were evaluated. The genetic algorithm with negative expansion tripled recall and doubled precision for low achievers, but high achievers displayed an opposed trend and seemed to be hindered in this condition. The effect of other conditions was less substantial.

An Examination of Factors Associated with the Use of Breast, Cervical, and Colon Cancer Screening Among Foreign-Born and Non-Foreign Born Individuals in the United States

Mariga, Netsai 12 August 2014 (has links)
Background: The number of Foreign Born (FB) individuals in the United States (US) is growing and their health behaviors and beliefs are important to know. In the US, cancer is the second leading cause of death, and there is need to explore factors that are associated with the use of cancer prevention strategies among FB individuals. Objective: The study aimed to compare cancer screening rates, assess factors associated with use of cancer screening tests across FB and Non-Foreign Born (NFB) individuals and association between length of stay and use of selected cancer screening tests among FB people. Methodology: Using the 2012 Health Information National Trends Survey (HINTS) 4, cycle 2 data, which comprised of 3,630 participants of which 513 were FB, logistic regression analyses were conducted to identify predictors of selected cancer screening tests. Independent variables included demographic and selected healthcare, beliefs, and information seeking factors. Results: There were no significant differences in screening rates for cervical, breast, and colon cancers among the FB and NFB individuals. For breast cancer screening, having had a routine checkup in the last year was found to be associated with increased likelihood of having a mammography exam. For cervical cancer screening, none of the selected healthcare, beliefs and information seeking factors was found to be significant among the FB individuals. For colon cancer screening, only the information seeking factor “it took a lot of effort to get cancer information” was found to be significant among FB individuals. Length of stay in the US for FB individuals was found be associated with increased likelihood of colon cancer test only. Conclusion: Inventive and ethnically appropriate strategies are essential to increase awareness for cancer prevention strategies. Well-designed information strategies that take into account the diversity of the US population can lead to benefits such as increased cancer screening.
