Web site credibility: Why do people believe what they believe?     

Marie K. Iding  Martha E. Crosby  Brent Auernheimer  E. Barbara Klemm 《Instructional Science》2009,37(1):43-63

This research investigates university students’ determinations of credibility of information on Web sites, confidence in their determinations, and perceptions of Web site authors’ vested interests. In Study 1, university-level computer science and education students selected Web sites determined to be credible and Web sites that exemplified misrepresentations. Categorization of Web site credibility determinations indicated that the most frequently provided reasons associated with high credibility included information focus or relevance, educational focus, and name recognition. Reasons for knowing a Web site’s content is wrong included lack of corroboration with other information, information focus and bias. Vested interests associated with commercial Web sites were regarded with distrust and vested interests of educational Web sites were not. In Study 2, credibility determinations of university students enrolled in computer science courses were examined for 3 provided Web sites dealing with the same computer science topic. Reasons for determining Web site inaccuracy included own expertise, information corroboration, information design and bias. As in Study 1, commercial vested interests were negatively regarded in contrast to educational interests. Instructional implications and suggestions for further research are discussed. Preliminary results from Study 1 were presented as a poster entitled “Users’ Confidence Levels and Strategies for Determining Web Site Veracity” (Iding et al. 2002a) and appeared in associated proceedings for The WWW 2002: The Eleventh International World Wide Web Conference, in Honolulu, Hawaii. Preliminary results from Study 2 were presented as a paper entitled, “Judging the Veracity of Web Sites” (Crosby et al. 2002) and appeared in associated proceedings for the International Conference on Computers in Education (ICCE 2002) in Auckland, New Zealand.  相似文献

Exploring the relationships between emotional intelligence and the use of knowledge transfer methods in the project environment     

Brent Decker  Rafael E Landaeta  Timothy G Kotnour 《知识管理研究与实践》2009,7(1):15-36

This exploratory investigation contributes empirical findings on the relationship between emotional intelligence and the use of knowledge transfer methods in the project environment. Emotional intelligence can be generally defined as the ability to effectively recognize and manage emotions to achieve individual and/or group objectives. Knowledge transfer has been generally defined as the process in which knowledge flows from knowledge sources to knowledge recipients. An exploratory hypothesis was tested using data collected from project managers and members of project teams from a variety of project-based organizations. The findings of this study suggest that there are noteworthy relationships between emotional intelligence factors and the use of specific methods to transfer knowledge within and across projects. The results of this investigation can be used by knowledge management researchers as a foundation for further research and development in the area of knowledge transfer and sharing in the project environment.  相似文献   

The effect of government contracting on academic research: Does the source of funding affect scientific output?     

Brent Goldfarb 《Research Policy》2008,37(1):41-58

The growing share of university research funded by industry has sparked concerns that academics will sacrifice traditional scholarly activities to pursue commercial goals. To investigate this concern, I examine the influence of an applied sponsor and consider limitations of the grant funding mechanism. A novel dataset tracks the careers of academic engineers and their relationships with this sponsor. I find that (a) researchers who maintain a relationship with the directed sponsor experience a decrease in publications implying that academics’ careers may be a function of the type of funding received, not only talent; (b) academic merit does not necessarily serve as a funding criterion for sponsors; and (c) citation and publication measures of academic output are often not useful proxies for short-term commercial or social value.  相似文献   

Impact of Fewer Questions per Section on SAT I Scores     

Brent Bridgeman  Catherine Trapani  Edward Curley 《Journal of Educational Measurement》2004,41(4):291-310

The impact of allowing more time for each question on the SAT I: Reasoning Test scores was estimated by embedding sections with a reduced number of questions into the standard 30-minute equating section of two national test administrations. Thus, for example, questions were deleted from a verbal section that contained 35 questions to produce forms that contained 27 or 23 questions. Scores on the 23-question section could then be compared to scores on the same 23 questions when they were embedded in a section that contained 27 or 35 questions. Similarly, questions were deleted from a 25-question math section to form sections of 20 and 17 questions. Allowing more time per question had a minimal impact on verbal scores, producing gains of less than 10 points on the 200–800 SAT scale. Gains for the math score were less than 30 points. High-scoring students tended to benefit more than lower-scoring students, with extra time creating no increase in scores for students with SAT scores of 400 or lower. Ethnic/racial and gender differences were neither increased nor reduced with extra time.  相似文献

Relative age effects in fitness testing in a general school sample: how relative are they?     

Scott Veldhuizen  John Cairney  John Hay  Brent Faught 《Journal of sports sciences》2015,33(2):109-115

When children or adolescents are grouped by age or year of birth, older individuals tend to outperform younger ones. These phenomena are known as relative age effects (RAEs). RAEs may result directly from differences in maturation, but may also be associated with psychological, pedagogic or other factors. In this article, we attempt to quantify RAEs in a simple fitness task and to identify the mechanisms operating.

Data come from a 5-year study of 2278 individuals that included repeated administrations of the 20 m shuttle run. We use mixed-effect modelling to characterise change over time and then examine residuals from these models for evidence of an effect for age relative to peers or for season of birth.

Age alone appears to account for RAEs in our sample, with no effects for age relative to peers or month of birth. Age grouping produces large disparities for girls under 12, moderate ones for boys of all ages and negligible ones for girls between 12 and 15.

RAEs for this task and population appear to arise from simple age differences. Similar methods may be useful in determining whether other explanations of RAEs are necessary in other contexts. Evaluation processes that take age into account have the potential to mitigate RAEs in general settings.  相似文献   

Is the environmental literacy of university students measurable?     

Kerry Shephard  John Harraway  Brent Lovelock  Sheila Skeaff  Liz Slooten  Mick Strack 《Environmental Education Research》2014,20(4):476-495

We report the development and piloting of an evaluative instrument and process for monitoring the environmental literacy (EL) of undergraduate students in one large research-led university in New Zealand. The instrument addresses knowledge, affect and competencies in the general area of EL in line with this institution’s adoption of EL as a graduate attribute (or in a US context, a general-education learning outcome, and something to be fostered throughout a student’s education). The instrument and associated processes were designed to fit within conventional institutional mechanisms that manage student feedback on the quality of teaching. The instrument was tested with more than 600 students from more than eight programmes over the course of a year and its use stressed that students were anonymous within the survey. We conclude that evaluating (or in a US context, assessing) the extent to which students acquire EL is an achievable objective and is a reasonable expectation for any higher education institution that claims to foster this attribute.  相似文献   

Struggling with theory? A qualitative investigation of conceptual tool use in instructional design     

Stephen C. Yanchar  Joseph B. South  David D. Williams  Stephanie Allen  Brent G. Wilson 《Educational technology research and development : ETR & D》2010,58(1):39-60

This study employed a qualitative research design to investigate instructional designers’ views and uses of conceptual tools in design work (e.g., learning theories and design theories). While past research has examined how instructional designers spend their time, how they generally make decisions, and expert-novice differences, little attention has been paid to the value and perceptions of conceptual tools, from the perspective of practicing designers. Based on intensive interviews of practitioners, our findings included ten themes organized according to three meta-themes: (a) using theory, (b) struggling with theory, and (c) connections between theory and intuition in craftwork. While these results substantiate (to some degree) the claim that practitioners often find theory too abstract or difficult to apply, they also suggest that practitioners use theory in several important ways and tend to view theory with ambivalence rather than indifference or dislike. Other conclusions regarding the role of theory in design are provided and future directions for theorizing and research are discussed.  相似文献   

Bracketed morality and ethical ideologies of sport fans     

Brent Smith  John B. Lord 《Sport in Society》2018,21(9):1279-1301

Historically, scholarship on ethics in sport has focused almost exclusively on practices of athletes, coaches and leagues. In this study, we highlight a serious void in the existing empirical literature on morality – ethical ideology and intention – of sport fans. Applying ‘bracketed morality,’ sport fans sometimes enact or accept behaviours otherwise regarded as problematic in everyday situations – insulting athletes, cursing at officials, celebrating riotously and/or intimidating fans of rival teams. Only some fans actually sanction (oppose) these kinds of behaviours, suggesting that they are questionable but not necessarily problematic, and, thus, worthy of closer investigation. Here, with the aid of four scenarios, we find that sport fans’ ethical ideology influences ethical intention. We also find that this influence is mediated twofold by ethical perception of moral problems and trivialization of observed situations, with trivialization exhibiting greater influence. Hence, while ethical ideologies and perceptions are important, they may be bracketed in evaluations of sport-fan behaviours.  相似文献
