This article discusses the information sources used by design, process, and manufacturing engineers in an international microchip manufacturing company, and the characteristics that influence their information source selection and use. Findings differ from previous research in three ways. First, there was a significant difference in these engineers' information behavior. Second, the higher the engineers' level of education, the less likely they were to depend on their personal memories as sources of information, and the more likely they were to rely on libraries. Third, the higher the level of engineers' education, the less likely they were to consider “personal mastery” (information tool mastery) as a source influencer.  相似文献

Health information seeking is an important part of older adults' everyday lives as they cope with their health conditions. Semi-structured interviews conducted with 21 older adults in the United States were analyzed using Savolainen's everyday life information seeking (ELIS) model, especially its key concepts such as way of life and mastery of life. The interview data revealed that except for health care providers, a spouse or partner was mentioned as a credible interpersonal source of health information among older adults in a marital or romantic relationship. Characteristics of older adults' health information behavior in the ELIS context were identified based on types of way of life and mastery of life. For example, those who had more varied types of hobbies, including cognitive, affective, and social hobbies, were exposed to diverse people as they performed their daily routine, potentially resulting in different sources of useful health information. In couple relationships, those with an optimistic as opposed to pessimistic attitude toward a problem-solving situation played the information provider role rather than information receiver role.  相似文献

The ways in which people perceive the relative value of the Internet when seeking information for self-development purposes were investigated. The concept of information source horizon was introduced, and it is a construct that enables one to put various information sources and channels in an order of preference to meet the requirements of information seeking. The horizon is based on one's conceptions of the characteristics of information sources, particularly their accessibility and quality. The study draws on interviews with eighteen Internet users who positioned various information sources in three zones of relevance. In their information source horizons, human sources such as friends and colleagues were preferred, followed by print media such as newspapers and books: networked sources were ranked third among six source types. Networked sources were favored for easy accessibility and opportunities to save time. The issue of “facilitating everyday life” was emphasized in this context. Also currency, broad repertoire of networked information, and the potential of the Internet to complement other services were valued highly. Critical stands on the Internet were mainly affected by the negative experiences of encountering low quality material.  相似文献

Objectives:

The research determined (1) the information sources that family physicians (FPs) most commonly use to update their general medical knowledge and to make specific clinical decisions, and (2) the information sources FPs found to be most physically accessible, intellectually accessible (easy to understand), reliable (trustworthy), and relevant to their needs.

Methods:

A cross-sectional postal survey of 792 FPs and locum tenens, in full-time or part-time medical practice, currently practicing or on leave of absence in the Canadian province of Saskatchewan was conducted during the period of January to April 2008.

Results:

Of 666 eligible physicians, 331 completed and returned surveys, resulting in a response rate of 49.7% (331/666). Medical textbooks and colleagues in the main patient care setting were the top 2 sources for the purpose of making specific clinical decisions. Medical textbooks were most frequently considered by FPs to be reliable (trustworthy), and colleagues in the main patient care setting were most physically accessible (easy to access).

Conclusions:

When making specific clinical decisions, FPs were most likely to use information from sources that they considered to be reliable and generally physically accessible, suggesting that FPs can best be supported by facilitating easy and convenient access to high-quality information.

Highlights

  • Medical textbooks were the most popular information source for family physicians'' (FPs'') clinical decision-making purposes, and medical journals were the most popular information source for the purpose of updating FPs'' general medical knowledge.
  • FPs considered medical textbooks to be the most reliable (trustworthy) source, colleagues the most physically accessible, and continuing medical education the most relevant and intellectually accessible.
  • The lowest ranked information sources across all four attributes were personal digital assistants, mental health professionals, pharmaceutical sales representatives, and other decision aids.

Implications

  • The most popular information sources for clinical decision-making purposes among FPs were sources characterized as reliable and generally physically accessible.
  • This study suggests the need for further research into interventions that target information access barriers in FPs'' practice settings and the promotion of reliable evidence for FPs'' clinical decision-making purposes.

跨源健康信息搜寻的动机、信息源选择及行为路径   总被引:1,自引:0,他引:1  
本研究旨在探究用户面临多种健康信息源时的跨源健康信息搜寻行为,揭示这类信息搜寻行为的动机、信息源选择和行为路径。结合日记法和半结构化深度访谈法,收集并分析了26名参加者的健康信息搜寻日记及跟踪访谈数据,使用NVivo11分析数据。研究发现医生-用户交流障碍、信任缺失、用户自我调节和用户安全心理的需要是促使跨源健康信息搜寻行为产生的动机。相似病症用户的自我陈述、用户的路径依赖(习惯)、从众心理、信息源的权威性及可信度是影响用户跨源过程中信息源选择的主要因素。此外,用户跨源搜寻健康信息的过程中,其心理需求大于实际需求、凭“感觉”感知网络健康信息质量等特征较明显。本研究构建了跨源健康信息搜寻行为路径模型,研究的结果有助于提升用户健康信息搜寻行为认知,改善其跨源健康信息获取能力,提升其健康信息素养;同时,也为相关部门制定提升公民健康信息素养策略及支持跨源健康信息搜寻行为的信息系统的开发和设计提供了借鉴。  相似文献

Much of health research that examines patterns of health utilization for chronic drug users fails to account for the role of media use and health information seeking. This paper suggests that the nature of drug use is associated with a decreased health orientation that is manifested in media selection and consumption. A comparative analysis was conducted to examine: (1) the differential health perceptions as a function of drug use, (2) the sources of information used, and (3) the relationship between sources of information and primary health care access among chronic users of illicit drugs and socio-demographically similar persons who are not chronic drug users. Results point to both common as well as differential patterns of health information sources. Logistic regression analysis found that medically related sources such as doctors and pamphlets are important sources associated with increased primary care. Important implications are discussed.  相似文献

This study examines US and South Korean journalists' use of sources and their perceptions of source credibility in covering the six-party talks on North Korea's nuclear ambitions. In particular, this study analyzes the relationship between journalists' perceptions of source credibility and the media's source use in terms of the aggregate and individual levels. Results of content analysis of US and South Korean newspapers are compared with data from a survey of US and South Korean journalists who covered the six-party nuclear talks. Government officials are dominant sources in media coverage of the talks because of their high level of accessibility and credibility. US and South Korean journalists assigned the greatest credibility to government officials of their own country. The two groups showed significant differences in their perceptions of credibility of South Korean officials, North Korean officials, Japanese officials, and Japanese experts. Moreover, this study finds that individual journalists' perceptions of source credibility were as strongly correlated with their individual use of sources as with the news media's aggregate use of sources. Implications of the findings are discussed in the context of media sociology, in particular gatekeeping.  相似文献

Research on librarians' roles and responsibilities often takes the form of content analysis of job advertisements found in aggregators such as print journals and websites. Whether these ads help us better understand librarianship depends on how representative the source data is for each study—the line going from jobs, to job ads, then to job ad sources. Print sources dominate even in studies published after 2000. This study examines where reasonably representative job advertisements for academic libraries may be found by starting at the origin: the institutions themselves. It finds that commonly used print sources provide only a small fraction of available positions (the majority of which are those in doctoral institutions), and even the most comprehensive aggregator misses nearly half of the available positions. Taking job ad samples directly from institutions is time-consuming but provides more representative data. Smaller colleges pose a particular challenge for finding ads as few of them have openings at any one time and few of their ads appear in national aggregators.  相似文献

The information-seeking behavior of lawyers has not been fully investigated empirically. Prior work has tended to focus on legal research as the central task performed by lawyers in their information-seeking activities. This analysis of more than 150 interviews of practicing lawyers showed that legal research should not be considered information-seeking. The lawyers interviewed identified other tasks, such as administration of their law practices, as constituting problem-solving, information-seeking activities. In solving their problems, the lawyers overwhelmingly preferred informal sources when seeking information. In addition, they preferred sources of information internal to their organizations rather than external sources, although this was less true for lawyers from smaller firms. Neither the lawyer’s gender nor the size of the center in which the practice was located influenced the type of information sources chosen. The model for the information-seeking behavior of professionals advanced by another author group is discussed and modifications are suggested that create a new model offering a fuller picture of the behavior of lawyers.  相似文献

Health disparities are a significant source of inequity between immigrants and native people in South Korea. The present study investigated how immigrants seek health information for their different purposes according to their health literacy ability and sociodemographic backgrounds. The study assessed immigrants' health literacy skills with the Rapid Estimate of Adult Literacy in Medicine (REALM) and conducted surveys (N = 310) in districts with high immigrant populations. Overall, there were significant associations between health literacy ability, sociodemographic characteristics, and health information-seeking behavior among participants. The findings of the study extend the literature by addressing the association between health literacy and health information-seeking behavior in diverse sociodemographic contexts. Understanding the dynamics between the three factors provides insights for developing effective health information services and public policies to mitigate health disparities experienced by immigrants, ensuring the critical roles of online health information and health professionals as preferred or credible sources.  相似文献

Parents are an important source of advice when adolescents are faced with decisions about postsecondary education and career planning; however, parents often need to seek information to facilitate their child’s career development. This study applies the theory of motivated information management (TMIM) to evaluate the decision-making process parents undergo in this context and tests the boundaries of TMIM by considering how individuals use face-to-face (FtF) and online sources to alleviate uncertainty-related anxieties. A community sample of parents (N?=?937) completed a survey regarding their information seeking behaviors surrounding their adolescent’s career development. Parents reported using both FtF and online sources to seek information about their child’s postsecondary plans, and they engaged in different evaluative processes depending on the source of information. Theoretical implications related to TMIM and practical implications related to parents as sources of information in adolescent career development are discussed.  相似文献

ABSTRACT

Trustworthiness is key in journalism, yet some journalists intentionally deceive their audiences by fabricating sources or inventing news stories altogether. Earlier research suggests that deceitful news articles have characteristics that are different from trustworthy news articles. We aimed to confirm and expand on the existing literature by examining the case of Perdiep Ramesar, an esteemed Dutch journalist until it was discovered in 2014 that sources were non-existing in 126 of his articles for national newspaper Trouw (“Fidelity”). Using content analysis, we searched for systematic differences in source use and presentation comparing Ramesar’s deceptive news articles with two same-sized sets of reliable articles, (1) articles on similar topics from other journalists and (2) articles with verifiable sources from Ramesar himself. Results indicate that compared to real news sources, fictitious sources are more often secondary definers, who are presented in more stereotypical ways and through more and longer direct quotations. Furthermore, negations and self-references occur more often in deceptive news articles.  相似文献

General results on transformations on information production processes (IPPs), involving transformations of the h-index and related indices, are applied in concrete, simple cases: doubling the production per source, doubling the number of sources, doubling the number of sources but halving their production, halving the number of sources but doubling their production (fusion of sources) and, finally, special cases of general power law transformations. In each case we calculate concrete transformation formulae for the h-index h (transformed into h*) and we discuss when we have h* < h, h* = h or h* > h.

These results are then extended to some other h-type indices such as the g-index, the R-index and the weighted h-index.  相似文献

The extent to which information sources, that stand behind virtually all the news, are perceived by journalists as credible is a key determinant of the likelihood of their obtaining news access and public voice. The nature of source credibility judgment in journalism, however, is disputed between two major schools: while the “visceral” camp contends that it is highly subjective, intuitive and biased, the “discretional” camp perceives it as a far more reasonable and legitimate journalistic tool. The present study attempts to uncover evidence of both “visceral” and “discretional” judgment by studying the conceptual credibility (trustworthiness ratings) and practical credibility (practices indicating trust or skepticism, such as cross-checking and attribution) and the congruence between the two in a sample of 840 news items based on 1870 news sources. Findings were gleaned in face-to-face reconstruction interviews with reporters from nine leading Israeli news organizations, who reconstructed, source by source, the processes behind their items, shortly after their publication. Pro-discretional evidence shows that while journalists perceive their own experience as more credible than that of any other human agent, they do tend to stick with sources they perceive as more credible, the majority of which were relied on in the past, granting them more ready acceptance. Pro-visceral evidence, in turn, demonstrates that even the least credible sources receive substantial news space, some without any cross-checking. Furthermore, reporters ranked their sources' credibility even when they had no former record of trustworthiness. The paper suggests interpreting the composite of these findings as discretional logic with islands of visceral judgment.  相似文献

TV evening news coverage of the 2008 presidential election by broadcast, cable, and public networks was predominately male and Caucasian in terms of reporters and sources. However, according to our content analysis of 888 campaign stories, viewers saw the least amount of source diversity if they watched the evening news on broadcast networks ABC, CBS, and NBC. Cable networks FOX and CNN, and the PBS evening news had more female and non-White sources. This pattern also holds true for reporter use of nonpartisan sources. Findings on the 2008 election for the traditional broadcast networks are not consistent with those for the 2000 and 2004 elections, when female reporters at these networks had more female and nonpartisan sources in their election coverage than did their male colleagues. Reporters at PBS provided the greatest overall source diversity, regardless of their race or gender, compared to what was observed on broadcast and cable networks. Differences in the way reporters used women and non-White sources to cover the 2008 presidential race may be attributable to organizational factors.  相似文献

This research examined how the interaction between a source's facial similarity to message targets and communicated bias affects audience persuadability. We used an evolutionary explanation to hypothesize that biased sources would elicit less favorable attitudes than unbiased sources for dissimilar sources, but that this difference would be absent for similar sources. Predictions were supported by results from a 2 (facial similarity) × 2 (source bias) experiment, in which an unrecognizable percentage of participants' photographs (n = 94) was digitally morphed with a source's face to act as a kinship cue. Further, structural equation modeling demonstrated a direct effect of facial similarity on attitude independent of mediation by source liking and appraisals, providing further evidence that susceptibility to influence from facially similar sources may have evolutionary origins.  相似文献
