Approximately 13% of Americans who provide care for an ailing family member do so from a distance, making long-distance caregiving a relevant health communication topic to study. A self-report online survey examined the quality of information provided by care recipient to distant caregiver, uncertainty about care recipient health, and perceived quality of care from the distant caregivers' perspective. Information quality, uncertainty, and perceived quality of care were significantly related as predicted. How these findings offer new insight into the complex nature of distant caregiving communication is discussed. 相似文献

The relationship between the development of mediated online literature searching and the recruitment of medical librarians to fill positions as online searchers was investigated. The history of database searching by medical librarians was outlined and a content analysis of thirty-five years of job advertisements in MLA News from 1961 through 1996 was summarized. Advertisements for online searchers were examined to test the hypothesis that the growth of mediated online searching was reflected in the recruitment of librarians to fill positions as mediated online searchers in medical libraries. The advent of end-user searching was also traced to determine how this trend affected the demand for mediated online searching and job availability of online searchers. Job advertisements were analyzed to determine what skills were in demand as end-user searching replaced mediated online searching as the norm in medical libraries. Finally, the trend away from mediated online searching to support of other library services was placed in the context of new roles for medical librarians. 相似文献

ABSTRACT Uncertainty is defined as affective symptoms of stress, anxiety, and frustration when faced with an information need. Traditional face-to-face instruction allows sender and receiver to fulfill information needs using multiple sources, which can be visual, auditory, tactile, or verbal. Distance learners may experience high levels of uncertainty when most or all of the communication and interaction takes place in an electronic environment that does not allow for these multiple information sources. Research on face-to-face communication and uncertainty suggests that people attempt to reduce uncertainty by acquiring more information and also by using structured or familiar information resources. This paper suggests that many of our behavioral motivations in face-to-face activities would also apply in the online environment. By creating online tutorials that combine structured hierarchical instructions with familiar modes of communication, we may be able to reduce symptoms of uncertainty in the library search process. 相似文献

This study explored the degree to which the perceived threat and resolvability of a serial argument are associated with relational uncertainty in a romantic relationship (i.e., self, partner, and relationship uncertainty). Participants included 147 individuals who were currently in a romantic relationship. Results revealed positive associations between argument frequency and relationship uncertainty, the perceived threat of the argument to the relationship and all three forms of relational uncertainty, and inverse associations between the perceived resolvability of the issue and all three forms of relational uncertainty. Interaction effects emerged for perceived threat by perceived resolvability for self and partner uncertainty, such that the resolvability of the issue diminished the strength of the positive association between the perceived threat of the argument and self and partner uncertainty. 相似文献

About 113 million Americans have reported seeking health information online; however, little is known about the quality (or qualities) of the information being retrieved. Users have reported seeking information about health issues in an attempt to reduce negatively appraised uncertainties (Brashers, 2007), but less is known about the ability of the retrieved information to increase or produce unwanted uncertainty. A content analysis of online cancer news was conducted and suggests that 65% of Internet-based cancer news contains message features previously linked to the production of uncertainty (e.g., ambiguous or complex information). Though future research is required regarding uncertainty-related content and its effects, this project provides a foundation for such future endeavors. 相似文献

Statistical analysis and comparison of library print and online holdings are used to reduce shelf area and inform index back-file purchases. Nikki DeMoville of California Polytechnic State University’s Robert E. Kennedy Library combined Counting Online Usage of Networked Electronic Resources (COUNTER) JR2 Access Denied usage reports, holdings information, and print circulation data to identify journals exhibiting a high desirability for online access and low print circulation. In this presentation, DeMoville shared how further combination of this data with ScienceDirect quote lists for back-file journal packages and Web of Science metrics could be used to support the efficient de-selection of print journals, allowing the library to recover the maximum amount of physical space while also acquiring backfile access to those titles most frequently needed in electronic format. The presentation detailed the workflows and comparative methodology used to reach collection management and development decisions for journal coverage, with an emphasis on before and after metrics. 相似文献

ABSTRACT This article investigates requirements and responsibilities for public library youth services librarians. Position advertisements were published in American Libraries in five-year increments, from 1971 to 2001. Youth services librarian positions were analyzed as to changes in position titles, education requirements, job responsibilities, and personality characteristics. Findings suggest that the number of advertised youth services positions is increasing, and job titles are changing from the specific “children's services” to the more generalized “youth services.” Advertised responsibilities of the youth services librarian have consistently emphasized collection management and administrative duties, and many advertisements place a heavy emphasis on personality traits. 相似文献

The research presented here examined the occurrence of the third-person perception (TPP) among children compared with older people. Unlike in previous research, the TPP was examined in response to positive product advertisements. These advertisements are considered negative only when people understand their persuasive intent and manipulative nature. In that context, there was no indication of the TPP in children, whereas adolescents and adults showed the usual effect. The research further documented the existence of an intuitive understanding of media influence on various age groups. For example, adults perceived themselves as less influenced by an adult-targeted ad than other adults but not less influenced than children and adolescents. The results are discussed in terms of self-serving bias, understanding of persuasion intent, and the intuitive understanding of media influence. 相似文献

In August of 1989, the Library of Congress selected fourteen libraries nationwide to participate in a pilot project to test and determine the feasibility and desirability of remote online access to the Library's information system. The California State Library was selected as one of the participant libraries. During the project, State Library staff performed 187 subject searches on various topics in the Library of Congress Information System (LOCIS). LOCIS was easy to search, and contained a variety of useful search features. Overall, staff found access to LOCIS to be a valuable addition to our existing online search services. 相似文献

Two hundred ninety-four job advertisements that appeared in MLA News in 1986 were analyzed to determine whether MLA certification had become a more frequent requirement than it was at the time of Schmidt and Swanton's 1980 study. Other qualifications studied were subject background, health sciences library courses, online searching experience, and OCLC experience. Library experience, educational requirements, and geographic distribution were also included. 相似文献

AbstractTo determine the state of the cataloging job market, this study compares job advertisements from August 2016-August 2018 advertising for jobs with cataloging in the title, metadata in the title, and cataloging and metadata in the title. Given ongoing concerns about the impact of metadata jobs on the cataloging job market, this study asks the questions: Are cataloging jobs in fact “disappearing” and becoming metadata jobs? Are entry-level jobs disappearing, perhaps contributing to the idea that there is a lack of qualified catalogers? Is there a difference in position level between cataloging and metadata job advertisements that can account for a lack or perceived lack of available cataloging jobs? Are there more entry-level or mid/supervisory positions advertised? Are cataloging and metadata jobs really separate, or should they be considered one position called cataloging and metadata? 相似文献

Online library resources can act as a trusted source to find various references for conducting research or writing research papers. With the increasing number of published papers, the use of online library resources becomes increasingly important for academics, including for university students. This study aims to investigate the factors that lead to the continued use of online library resources among university students in developing countries, especially Indonesia. We investigate the impact of resource quality, confirmation, satisfaction, perceived usefulness, perceived ease of use, and perceived enjoyment of users on their intention to continue using online library resources and the effect on e-WOM intention. This study will enhance the Post-Acceptance Model of Information System (IS) Continuance by adding several other constructs and tested using data from 215 university students in Indonesia who have used online library resources. The method used to analyze the data is Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results of the study indicate that satisfaction and perceived enjoyment have a significant effect on the intention to continue using online library resources. In addition, it was also found that the continuation intention to use online library resources also affects the user's intention to convey it to others (e-WOM intention). This study provides insight to online library resources service providers in making improvements and formulating strategies to increase users' intentions to continue using their online library resources. 相似文献

SUMMARY Librarians are often hampered by the limitations of online catalog systems because of a lack of flexibility in how they present relationships among serial information objects and their bibliographic surrogates. Therefore librarians have to look outside the box and consider other methods for enhancing bibliographic clarity and access. They also have to be forward thinking and develop an information environment that is less encumbered by machine-imposed strictures such as linearity, polarization of viewpoint and visual constraint. 相似文献

In order to develop more effective ways of helping adolescents and young adult (AYA) cancer survivors cope with cancer-related uncertainty, it is important to understand how AYAs respond communicatively to each other's uncertainty. We designed this project to gain insight into the patterns of social support that occur in response to AYAs' expressions of uncertainty. We analyzed 510 responses to posts in an AYA-focused online discussion group. Eighty-two percent of messages responding to uncertainty contained informational support. Sixty-seven percent contained multiple types of support. Among medical, personal, and social sources of uncertainty, the most typical response tended to be a combination of informational support accompanied by emotional and/or esteem support. AYAs who express uncertainty in online support groups should be advised that their posts are likely to be met with information, such as advice and referrals, which may either facilitate or impede their uncertainty management goals. 相似文献

This experiment investigates the effects of an advertorial message on 4 dimensions of reader involvement. The use of the advertorial format was found to have increased participants' perceived message relevance, attention to written message, message elaboration, and message recall over the use of a standard advertisement format. Responses to labeled and unlabeled versions of the same advertorial did not vary significantly. Although participants perceived both labeled and unlabeled advertorials to be advertisements, rather than editorial material, more than two thirds of the participants who were exposed to a labeled advertorial failed to recall the presence of the label. Our findings indicate that the advertorial format fools readers into greater involvement with the advertising message and that the presence of advertorial labels may not be particularly effective in alerting consumers to the true nature of the message. 相似文献
