Information behaviour of researchers at Sultan Qaboos University

Al-Mughairi, Ali J. January 2006 (has links)
The present study investigates the information gathering behaviour of the academic researchers at Sultan Qaboos University in the Sultanate of Oman. It endeavours to explore researchers' awareness and attitudes towards information sources and services. Research methods for this study were designed from the user-centred perspective with triangulation approach. Hence, data was collected by the use of semistructured interviews as the main instrument with journal study and observation as supplementary tools. The information was collected from the members of the research community in their capacity as users of information. The study investigates the information needs and information gathering habits of the research community and attempts to identify the problems experienced by researchers in accessing and using information. It also seeks to explore the national policy for planning and provision of information. Finally the study examines the performance of the various information services in the context of user needs and the status of the institution library information service provision. The research concludes that present information environment at Sultan Qaboos University is inadequate to meet the information needs of the research community. It was found that the major causes for the situation was the lack of clear information policies, inadequate funding, ineffective partnership between top management and academic researchers, lack of effective in house training and finally absence of a reliable information technology infrastructure.

Identifying factors of millennial publics risk information seeking and processing strategies of genetically modified food

D'Angelo, Jeremy Martin January 1900 (has links)
Master of Science - Agricultural Education and Communication / Department of Communications and Agricultural Education / Jason D. Ellis / Genetically modified crops have been beneficial to farmers in terms of saved time, money, and energy while increasing yields and often times reducing pesticide dependency. These benefits outweigh the increased costs, allowing genetically modified crops to become one of the fastest adopted farm technologies in history. Despite overwhelming approval of genetically modified crops among farmers, consumers have been hesitant to consume genetically modified food. Consumers see genetically modified food as a risk without immediate reward. Millennial consumers are a powerful population segment that rivals or overtakes other population segments in terms of size, influence, and purchasing abilities. Yet, they are often lumped into one homogenous group by marketers when they are a diverse group comprised of unique segments. The purpose of this study was to better understand how millennial consumers find and process risk information about genetically modified food so that agricultural communicators can better strategize communication efforts. Applying the Situational Theory of Publics and the Risk Information Seeking and Processing Model, this study went one step further by differentiating between Supportive and Non-supportive publics. The research objectives of this study are as follows: 1) Identify the individual characteristics of both Supportive and Non-supportive millennial publics of genetically modified food; 2) Examine relevant channel beliefs of Supportive and Non-supportive millennial publics of genetically modified food; 3) Identify and describe the information gap of Supportive and Non-supportive millennial publics of genetically modified food; 4) Define the perceived information gathering capacity of Supportive and Non-supportive millennial publics of genetically modified food; and 5) Characterize the information seeking and processing behavior of Supportive and Non-supportive millennial publics of genetically modified food. An Internet survey was distributed to individuals between the ages of 18 and 36 within the United States. The majority of Non-supportive publics had a high level of issue involvement and the majority of Supportive publics had a low level of issue involvement. Meaning, the majority of Non-supportive publics are more active about the issue than Supportive publics. Age was found to be correlated with systematic processing and information avoidance with older millennials more likely to systematically process information and less likely to avoid information. Additionally, this study found that regardless of knowledge level, wealthier individuals who do not support genetically modified food are more likely to be actively involved in the issue and wealthier individuals who support the technology are more likely to be passive about the issue. The majority of millennial publics in all eight groups reported a knowledge deficit to some degree. The research also found that heuristic processing was negatively correlated to systematic processing and higher levels of information avoidance were negatively correlated with lower levels of active information seeking. Non-supportive Active publics (high issue involvement/high knowledge) were found to have the highest mean active information seeking and systematic processing scores and lowest mean heuristic processing and information avoidance scores; supporting past findings that knowledge does not always equate to support and that communication practitioners may have trouble changing the opinion of a large portion of Non-supportive publics.

Needs of familial caregivers of cancer patients across the advanced cancer disease trajectory.

Bernard, Lori Lynn 08 1900 (has links)
Familial caregivers are providing increasing amounts of care to advanced cancer patients. Increased understanding of caregivers' needs is vital in providing necessary support to lessen caregiver burden and comorbidity. This study examines particular information needs across a variety of specific events in the advanced cancer disease trajectory. A cross-sectional sample of 107 familial caregivers (24 current and 83 bereaved) of people with advanced cancer completed a needs assessment survey along with a measure of health information-seeking behavior. Analyses extend current research by including more specific disease-related events along the advanced cancer trajectory through bereavement. In all information categories, endorsement of wanted information differed across broad stages of Cancer Progression, Treatment, End of Life, and Post-Patient Death. For all information categories, except Dying and Spirituality, greatest information was wanted at the Cancer Progression stage. Information need also differed across specific events within broad stages. The categories of Disease/Medical and Relating to the Patient were the most endorsed at events involving patient care. Spirituality was least endorsed. At patient death, Caregiver Well-being has the highest endorsement. For events thereafter, information on Caregiver Well-being, Spirituality, Future Outlook, and Family and Close Others was most endorsed. Information needs did not differ based on age or education. Whether or not a caregiver had experienced a given event on the cancer trajectory impacted some categories of information desired at the events of leaving the hospital for home, going into hospice, patient death, immediately after death, and bereavement. In all cases, those who had experienced the event wanted more information. In comparing current to bereaved caregivers, no differences in information endorsement occurred for events of the Cancer progression or Treatment stages. This study also involved the validation and factor analysis the Health Information-Seeking Behavior Survey. Two factors, Health Information-Seeking and Health Information-Avoiding, emerged. Health Information-Seeking correlates positively with some of the information categories at some of the stages. Increased understanding of caregiver needs at specific key events in the advanced cancer illness trajectory can now be used to inform the development of effective familial caregiver education interventions.

Self-Perceived Information Seeking Skills and Self-Esteem in Adolescents by Race and Gender

Simpson-Scott, Lynne 05 1900 (has links)
The purpose of this study was to explore the correlation between self-perceived information seeking skills and self-esteem in adolescents and, further, to determine whether this correlation varied according to race and gender. Tenth-grade students from three public high schools in a Midwestern city were given two instruments. Self-perceived information seeking skills were measured using a modified version of the Information Skills Checklist from High Plains Regional Technology in Education Consortium's Profiler website. Self-esteem was measured by the Tennessee Self-Concept Scale, which is designed for students 12 years of age and over. The scale has six separate measures of self-esteem: physical, moral-ethical self, personal self, family self, social self and academic self. These six measures are used to determine overall level of self-esteem. The results showed a statistically significant correlation between self-perceived information seeking skills and at least one facet of self-esteem for all groups measured, with one exception. African American males were the only adolescents to show no correlation between scores from these two instruments. It is hoped that this research will ultimately be used to develop policies regarding the development of information seeking skills in disenfranchised groups.

The transformative library: A narrative inquiry into the outcomes of information use.

Kenney, Brian 12 1900 (has links)
This qualitative study uses narrative analysis to explore the outcomes of information seeking and use among public library users. Twelve women between the ages of 51 and 72, all residents of Fayetteville, Arkansas who self-identified as regular library users, were interviewed to gather their life stories and their experiences using the public library. The participants in this study used information to enable learning and, often, a change in their affective state. The participants used the new information they encountered constructively, to engage with the knowledge and experience they possessed; this use of information always involved reflection, dialogue, or both. The outcomes from these actions are the creation of new knowledge, a change in the participants' meaning schemes, and/or an affective change. In addition, the narratives strongly suggest that information seeking and use by adults in public libraries can sometimes facilitate or, on its own, precipitate a perspective transformation and the adoption of new meanings. Overall, the findings support Mezirow's theory of transformative learning as a model for understanding information use and outcomes among users of the public library. The major implications of this study are two-fold. One, it introduces to information science Mezirow's theory of transformative learning which could provide greater understanding of how adults use information, and the outcomes that arise from this use. Two, it provides library professionals with information about the library in the lives of their users and concrete information about how libraries can enable transformative learning.

Business information needs, seeking patterns and information services in the small medium and micro enterprises sector (SMME) in Namibia

Chiware, Elisha Rufaro Tembo 05 February 2008 (has links)
This thesis reports on a study conducted to investigate the business information needs, seeking patterns and information services for small, micro and medium enterprises (SMMEs) in Namibia. The survey methodology was used and questionnaires were distributed to 308 SMMEs and 60 business service providers in the Windhoek and Oshana districts of Namibia. An in-depth qualitative assessment of the business information services was also conducted in 15 business support organisations in the two districts. The data collected through questionnaires was analysed using the Statistical Package for Social Sciences (SPSS) while qualitative data was analysed using content analysis. The study revealed that SMMEs have a range of business information needs and top among them are information on: finance, marketing, training and business information. The study also revealed that the information seeking patterns of SMMEs are largely informal with limited use of formal business information services provided by a range of business support services. There are several business support organisations in Namibia providing a range of services, including the provision of business information services. However, the study established that there is need for a coordinated approach towards the provision of business information services in the SMME sector in Namibia. The study showed that the utilisation of ICTs among SMMEs is very limited to basic computer operations like word processing, book-keeping packages, and spreadsheets. The use of Internet as a business tool and source of business information among SMMEs is also very limited. However, the study shows that the utilisation of ICTs among business support organisations is advanced and that this could be used as a platform to improve information delivery services to the SMMEs. The study proposes a strategic model that could be used in the deployment of business information services in the SMME sector. This strategy is based on a definition of business information services, components of business information services and the steps that must be followed in the development of the services. The proposed strategy also outlines the steps that should be taken in the impact assessment of business information services. The study concludes by making several recommendations concerning the improvement of business information delivery services to the SMME sector. Business support organisations and, in particular government and Chambers of Commerce and Industry need to consider various approaches in the design of sustainable business information services. / Thesis (DPhil (Information Science))--University of Pretoria, 2008. / Information Science / unrestricted

The impact of political cues on information seeking and the need for cognitive closure

Scherer, Aaron 01 May 2014 (has links)
Previous research has demonstrated that the political ideology one adopts is strongly influenced by three social-cognitive motives: motives to reduce uncertainty, manage threats, and experience solidarity. The goal of the current studies was to examine the possibility that this relationship might also work in reverse, with political ideology influencing social-cognitive motives. To this end, four studies examined the impact of conservative cues on need for cognitive closure (NFCC), a measure of motivation to reduce uncertainty, and tested between three accounts of the impact of conservative cues on selective exposure (SE) to confirming information, the primary measure of NFCC in the current studies. Studies 1-3 examined how exposure to the American flag, a conservative cue, impacted SE (Studies 1 and 3) and the accessibility of NFCC (Study 2). Study 4 examined how exposure to partisan news sources impacted SE. Exposure to conservative cues may increase SE by making political group membership salient, resulting in the defensive engagement in SE to maintain a positive view of one's political in-group (social identity account), or by priming the political stereotype that conservatives are high in NFCC, which individuals (stereotype priming account) or only conservatives (active self-concept account) assimilate towards. The four studies produced mixed results, but overall, were most supportive of the stereotype priming account. Specifically, there was evidence that exposure to conservative cues increased SE (Studies 1 and 3) and made NFCC more accessible (Study 2). Additionally, these results were not moderated by political ideology, as predicted by the active self-concept account, and there was no evidence of increased affiliation with one's political in-group, as predicted by the social identity account. In Study 4, exposure to the conservative news source reduced SE compared to exposure to the moderate and liberal news sources, results inconsistent with all three accounts. Theoretical and practical implications, as well the complexities of the current studies' results, are discussed.

The Denial of Relevance: Biography of a Quest(ion) Amidst the Min(d)fields—Groping and Stumbling

VanBebber, Marion Turner 08 1900 (has links)
Early research on just why it might be the case that “the mass of men lead lives of quiet desperation” suggested that denial of relevance was a significant factor. Asking why denial of relevance would be significant and how it might be resolved began to raise issues of the very nature of questions. Pursuing the nature of questions, in light of denial of relevance and Thoreau’s “quiet desperation” provoked a journey of modeling questions and constructing a biography of the initial question of this research and its evolution. Engaging literature from philosophy, neuroscience, and retrieval then combined with deep interviews of successful lawyers to render a thick, biographical model of questioning.

Web Information Behaviors of Users Interacting with a Metadata Navigator

McMillan, Tyson DeShaun 12 1900 (has links)
The web information behaviors of users as they interacted with a metadata navigator, the Personal Information (PI) Agent, and reflected upon their interaction experiences were studied. The process included studying the complete iterative (repeated) cycle of information needs, information seeking, and information use of users interacting with an internet-based prototype metadata PI Agent tool. Detlor’s theory of web information behaviors of organizational users was utilized as a theoretical foundation for studying human-information interactions via the PI Agent tool. The qualitative research design allowed for the use of triangulation within the context of a one-group pretest-posttest design. Triangulation occurred in three phases: (a) observe, (b) collect, and (c) reflect. Observations were made as participants solved three problem situations. Participants’ computer log and print screen data were collected, and follow-up interviews were conducted once all posttest sessions ended to enable users to reflect on their experiences. The three triangulation phases ensured saturation of data and greater depth regarding the participants’ information behaviors. Content analysis occurred via exploratory pattern analysis using the posttest Problem Steps Recorder (PSR) log data and on the six interviewees’ follow-up interview data. Users engaged in iterative cycles of information needs, information seeking, and information use to resolve the presented problem situations. The participants utilized the PI Agent tool iteratively to eliminate their knowledge gaps regarding the presented problem situations. This study was the first to use PSR log data for capturing evidence of the iterative search process as defined by Detlor. The implications for best practices were inspired by participant feedback, and recommendations for further study are made.

Évaluation d'outils d'accès à la connaissance en médecine générale / Evaluation of access to knowledge tools in general medicine

Schuers, Matthieu 19 October 2017 (has links)
Les médecins, et en particulier les médecins généralistes, sont confrontésquotidiennement à la difficulté de ne pas tout savoir. En médecine générale, l’étendue duchamp d’activité impose aux professionnels une maîtrise de plus en plus aiguë del’information, qui doit s’appuyer sur le développement d’une littératie numérique, c’està-dire la capacité d’utiliser et de comprendre les outils et médias numériques. Lesobjectifs de ce travail étaient d’identifier les obstacles à la recherche d’information chezles médecins généralistes et de développer et d’évaluer des outils susceptibles desurmonter ces difficultés.Pour cela, nous avons réalisé une étude qualitative auprès d’internes de médecinegénérale et de médecins généralistes français. Elle a permis de mettre en évidence denombreux obstacles à la recherche d’informations en santé en ligne. Ces obstaclesconcernent les professionnels et les outils, certains sont également d’ordre institutionnel.Parmi ces obstacles figure la langue anglaise, qui semble constituer un repoussoir pourles médecins installés mais également pour les médecins en formation. D’après lesdonnées que nous avons recueillies, ce frein concerne aussi bien l’information en ellemêmeque son support.Plusieurs des outils développés par l’équipe du Département d’Informatique etd’Information Médicales du CHU de Rouen ont vocation à répondre à ces difficultés. Labase de données bibliographiques LiSSa permet l’accès à plusieurs centaines de milliersde références francophones en santé, issues de PubMed mais également de revuesfrancophones non indexées dans PubMed. Le constructeur de requêtes bibliographiquesmédicales permet à des utilisateurs non anglophones de construire des équations derecherche complexes dans leur langue maternelle, leur permettant de requêter dansPubMed, LiSSa ou CISMeF. / Physicians, and especially general practitioners, are not « all-knowing ». As they areconfronted with a large amount of clinical situations, information and knowledgemanagement are essential topics of interest. This management is mainly based on thedevelopment of numeric literacy, that is the ability to use and understand digital tools andmedia. The aims of this work were to identify the obstacles encountered by generalpractitioners when seeking health information online and to develop and assess tools tohelp them to overcome these barriers.We performed a qualitative study among general practice residents and generalpractitioners. This allowed us to highlight several obstacles encountered by them whenseeking medical information online. These obstacles include both tools and professionals’issues. Institutional obstacles were also identified. Of these barriers, the insufficientcommand of English was cited as an important issue by both residents and physicians.The Department of Medical Information and Informatics of the Rouen University Hospitalhas developed several tools in order to facilitate access to knowledge for healthprofessionals. LiSSa is a bibliographic database containing only articles written in French.It allows health professionals and researchers, whose native language is not English, toaccess to hundreds of thousands of references, from PubMed and from journals notindexed in PubMed. A multi-lingual query builder to facilitate information retrieval wasdesigned. It appears to be an effective tool to improve the quality of PubMed queries inparticular for users whose first native language is not English.
