Research on publication and citation patterns generally focuses on prolific or highly cited authors or on highly ranked programs. This study investigates the work and influence of a cross-section of library and information science (LIS) researchers at various stages of their academic lives, using a random sample of faculty members at programs accredited by the American Library Association. The analysis shows that the number of publications increases steadily as faculty rank advances. Assistant professors publish more conference papers and fewer journal articles, a pattern that is reversed with associate and full professors. Researchers used Web of Science® and Google™ Scholar to determine the influence of the publications. Web of Science reported no citations for most LIS faculty publications. With its broader scope, Google Scholar located more citations and revealed that the works of professors are cited significantly more frequently than publications by assistant or associate professors. When faculty profiles are compared by type of program, faculty members at schools granting doctoral degrees publish significantly more than their counterparts at schools where there is no doctoral program or where the doctoral degree is offered jointly with other academic units. When the comparison is made across ranks, full professors publish significantly more than faculty members at other ranks. There is no significant difference between assistant and associate professors. 相似文献

In Experiments 1 and 2, honeybee foragers visiting the laboratory were fed on targets of two different colors, one containing 5 μl and the other containing 20 μl of 50% sucrose solution. The targets were presented singly in quasi-random sequences on the training visits, after which preference was measured in an unrewarded choice test. In Experiment 1, 16 differentially rewarded training trials with each color were followed by the same number of trials with the color-amount relation reversed; no preference for either color was found in the subsequent choice test. In Experiment 2, 20 differentially rewarded training trials with each color—enough to produce a clear preference for the 20-μl color when given directly after pretraining—were given after 10 feedings to repletion on each color that were calculated to generate near-asymptotic associative strength; no preference for either color was found in the subsequent choice test. In Experiment 3, there were 12 feedings to repletion on one color and, on the other, 12 feedings to repletion followed by 15 trials with a small (5 μl) reward; no preference was found in a subsequent choice test. The results of all three experiments support a nonrepresentational interpretation of the role of amount of reward in the learning of honeybees. 相似文献

This study used a large (N = 519), longitudinal sample of adoptive families to test overreactive parenting as a mediator of associations between parental depressive symptoms and early childhood externalizing, and parents’ social support satisfaction as a moderator. Maternal parenting (18 months) mediated the association between maternal depressive symptoms (9 months) and child externalizing problems (27 months). Paternal parenting was not a significant mediator. Unexpectedly, we found a cross-over effect for the moderating role of social support satisfaction, such that partners’ social support satisfaction reduced the strength of the association between each parent's own depressive symptoms and overreactive parenting. Results point to the importance of accounting for broader family context in predicting early childhood parenting and child outcomes. 相似文献

Around the world, governments turn to information technology (IT) training programs to enhance equitable delivery of online public services to citizens. However, the effectiveness of these citizen training programs has gone unexplored. This study is motivated by two objectives: 1) To evaluate whether citizen participation in government training programs is associated with greater e-government use among participants, and 2) To assess whether the strength of this relationship varies according to whether a citizen is elderly, disabled, or not – those who are elderly or disabled tend to use e-government the least. We use data from South Korean to examine these objectives. Findings indicate citizen participation in government IT training programs is positively associated with e-government use and that this relationship is stronger for citizens who are elderly or disabled. These findings highlight the potential of government IT training programs to mitigate the digital divide. Implications for research and practice are discussed. 相似文献

This paper focuses on the role of the computer system in group decision-making. Two systems used in solving negotiating problems and three procedures which can be utilized to develop group decision support systems are analysed and a unified approach for the analysis is presented. The systems and procedures are based on multicriteria decision analysis and use mathematical programming models. They can play different roles: systems intervention in the negotiating process can be used merely to facilitate the process, or the system can actively mediate negotiations; both roles are discussed here. 相似文献

OBJECTIVE: To determine how often and for what reasons a hospital-based multidisciplinary child abuse team concluded that a report of alleged or suspected child abuse was unnecessary in young children with fractures. METHODS: A retrospective review was completed of all children less than 12 months of age who, because of fractures, were referred to the hospital multidisciplinary child abuse team for consultation regarding the need to consider child abuse. RESULTS: The team received 99 consultations, reported 92 (93%) children as alleged or possible victims of physical abuse, and did not report 7 (7%). Age at presentation of those who were reported was 4.2 months compared to 3.0 months in the non-reported group. The average number of fractures in the reported group was 2.9 (SD 3.53) compared to 3.4 (SD 4.6) in the non-reported group. Factors that led to cases not being reported included: (a) a trauma history consistent with the fracture (n=4), (b) a diagnosis of bone fragility secondary to genetic, nutritional or medical therapy etiologies (n=2), and (c) iatrogenic fracture (n=1). CONCLUSIONS: Seven percent of the children less than 12 months of age and with at least one fracture referred to the multidisciplinary team for evaluation of possible child abuse were not reported as alleged or suspected physical abuse. The involvement of the hospital multidisciplinary child abuse team may have prevented unnecessary investigation by the county social services agency and/or police, and possible out-of-home temporary placement. 相似文献

This paper reports results from evaluation of the Cosmic Ray Observatory Project (CROP), a student, teacher, scientist partnership
to engage high-school students and teachers in school based cosmic ray research. Specifically, this study examined whether
an intensive summer workshop experience could effectively prepare teacher—student teams to engage in cutting edge high-energy
physics research. Results showed that teachers and students could acquire enough knowledge about cosmic ray physics and self-efficacy
for conducting cosmic ray research during a summer workshop to be full participants in an SSP conducting research in their
schools, and a capstone anchoring approach using an authentic research activity was effective for motivating student engagement
in didactic classroom learning. CROP demonstrated “proof of concept” that setting up cosmic ray detector arrays in schools
run by teachers and students was feasible, but found that set-up and operation in a high-school was technically difficult. 相似文献

This article uses results from a cross-national analysis of the impact of varying approaches to civic education curriculum delivery on three learning outcomes, to draw conclusions about the value of a government-mandated compulsory, independent subject of civic education in the school curriculum. It starts from the context of Hong Kong, where there have been repeated calls for the government to reform civic education, and compares this context with that of England, where citizenship education was made a statutory subject in 2002. The article then examines from the cases of 25 societies whether a compulsory approach to and/or independent subject of civic education is associated with better learning of civic knowledge, knowledge of democracy, and patriotism. Finding that the impact of curricular approaches is somewhat negligible taking other factors into consideration, the article concludes that civic education reformers should consider the costs of limiting school autonomy in curriculum delivery. 相似文献
