At a top psychology journal, Psychological Science (PS), submissions peak during the summer months. We tested whether this seasonal submission bias decreases the likelihood of a paper being accepted in that period. Month of submission data was obtained for all 575 publications in PS for the period 2003–2006. Whereas submissions to PS were higher in the summer, there was no evidence that most accepted publications were originally submitted in the summer. Thus, contributors submit to PS when the likelihood of acceptance is the lowest – creating their own entrance barrier. A similar seasonal pattern was not identified for Personality and Social Psychology Bulletin, another top psychology journal. Using the Web of Knowledge database, we further assessed whether overcoming the seasonal entrance barrier influences the number of citations a paper receives in subsequent years. We discuss the possibility that the different rejections policies in the two journals, employing desk rejections or not, may explain this discrepancy, and explore a range of alternative hypotheses.  相似文献

The Congress for Cultural Freedom is remembered as a paramount example of the “cultural cold wars.” In this paper, I discuss the ways in which this powerful transnational organization sought to promote “science studies” as a distinct – and politically relevant – area of expertise, and part of the CCF broader agenda to offer a renewed framework for liberalism. By means of its Study Groups, international conferences and its periodicals, such as Minerva, the Congress developed into an influential forum for examining the ways Big Science impacted the relations between science, society, and politics, thus constituting a semi-institutional niche for Science Studies before its professionalization within academia during the 1970s. I argue that the Congress contributed to the construction of public space in which the relations between science, society and politics were debated, and science was reconceptualized as a social activity. The vision of “science studies” the CCF-associated intellectuals promulgated was different from the science studies we know today. Yet, this alternative vision, in which the issues of science politics appeared inseparable from those of science policy, science organization, and science governance, constituted the “pre-history” of science studies today.  相似文献

The principle of a new type of impact measure was introduced recently, called the “Audience Factor” (AF). It is a variant of the journal impact factor where emitted citations are weighted inversely to the propensity to cite of the source. In the initial design, propensity was calculated using the average length of bibliography at the source level with two options: a journal-level average or a field-level average. This citing-side normalization controls for propensity to cite, the main determinant of impact factor variability across fields. The AF maintains the variability due to exports–imports of citations across field and to growth differences. It does not account for influence chains, powerful approaches taken in the wake of Pinski–Narin's influence weights. Here we introduce a robust variant of the audience factor, trying to combine the respective advantages of the two options for calculating bibliography lengths: the classification-free scheme when the bibliography length is calculated at the individual journal level, and the robustness and avoidance of ad hoc settings when the bibliography length is averaged at the field level. The variant proposed relies on the relative neighborhood of a citing journal, regarded as its micro-field and assumed to reflect the citation behavior in this area of science. The methodology adopted allows a large range of variation of the neighborhood, reflecting the local citation network, and partly alleviates the “cross-scale” normalization issue. Citing-side normalization is a general principle which may be extended to other citation counts.  相似文献

The purpose of this study was twofold: to examine how attitudinal and instructional variables differentiated 4th-grade students in Cyprus, Hong Kong, and the USA; and to determine how those variables were related to math performance on the TIMSS test. A discriminant analysis was performed to examine how those variables differentiated the students in the 3 countries. The most striking result was that the students from all 3 countries, who were similar to the average students in Cyprus, had the highest achievement within their countries. Thus, 4th-grade students who liked math, who thought it was important to do well in math for their friends, who did not need private instruction, and who had not been taught using computers or small group procedures, tended to be the better students. However, students who were similar to the average USA student had the lowest achievement within each of the 3 countries.  相似文献

The paper aims to further explore the role that culture plays in the provision and assimilation of sex education among Latina immigrants in the USA. To accomplish this, researchers conducted focus groups and interviews with 30 women from Central and South America who have lived in the USA for at least five years. Participants were asked to reflect on their experience with sex education in their home country and in the USA, and to assess how their attitudes towards sex education may impact their behavioural choices as parents and as sexually-active women. The findings demonstrate a wide range of views that did not follow patterns by common demographical proxy variables, suggesting that such variables are not enough to predict adoption of new cultural values that are different from their family's traditional norms. Instead, adherence to traditional cultural beliefs appeared to be a better predictor of attitudes and behaviours.  相似文献

Substantively, this study investigates potential heterogeneity in the developmental trajectories of anxiety in adolescence. Methodologically, this study demonstrates the usefulness of general growth mixture analysis (GGMA) in addressing these issues and illustrates the impact of untested invariance assumptions on substantive interpretations. This study relied on data from the Montreal Adolescent Depression Development Project (MADDP), a 4-year follow-up of more than 1,000 adolescents who completed the Beck Anxiety Inventory each year. GGMA models relying on different invariance assumptions were empirically compared. Each of these models converged on a 5-class solution, but yielded different substantive results. The model with class-varying variance–covariance matrices was retained as providing a better fit to the data. These results showed that although elevated levels of anxiety might fluctuate over time, they clearly do not represent a transient phenomenon. This model was then validated in relation to multiple predictors (mostly related to school violence) and outcomes (grade-point average, school dropout, depression, loneliness, and drug-related problems).  相似文献

To know whether students' achievements are the result of online interaction and not just a consequence of individual differences themselves, it seems essential to link the cognitive results to the students' online behavior (technological presence). In technological presence, interaction is based on the degree in which the online student senses the availability of, and connectedness with, other students, the teacher, and the context. Cognitive presence as a part of the interaction process of teaching and learning reflects the level of accomplishment in online learning environments (cognitive attainment). The purpose of this article is to show some evidence of the mutual influence of the students' technological behaviors and the students' cognitive factors in online learning environments – including teacher and instructional design factors. Two thousand one-hundred thirty written computer-mediated communications from 88 participants in four prototypical online learning activities have been analyzed for this purpose. The analysis shows the influence of technological presence on the quality of learning results of the online knowledge construction process. The conclusions point out the importance of considering technological presence as a new and complementary type of presence as it provides relevant information for instructional and technological design.  相似文献

The study looks into the problem of student–faculty communication. It addresses the issue of claimed scarcity of such interaction that exists despite the recognized benefits it can bring to students and instructors. It is suggested that examination and comparison of the participants’ interest and actual engagement in out-of-class communication (OCC) may shed light on this. Two populations from a university in Russia: 148 students and 35 instructors, were analyzed to measure their overall interest and engagement in OCC. The paper also addressed the question whether the studied populations are interested and engage in the same types of OCC. The results demonstrate that the reported overall interest in OCC was higher than the actual engagement in it among both groups of the respondents. Besides, students and faculty chose different types of OCC as most interest evincing and most frequently practiced. The research outcomes may help the parties concerned (scholars, teaching staff, educational managers and students) enhance understanding of the nature of OCC and its specifics and consider ways of harmonizing it in the best interests of all stakeholders.
