As collection budgets have dwindled, library acquisitions has become a data-driven field that relies on hard numbers. Libraries are struggling with the demands of adapting to a numbers-driven environment, both from a personnel and a data management perspective. This article includes a literature review, survey results, and practical advice that can be applied to most library environments. A model of transferable outcomes is introduced that encourages libraries to create a data pool of statistical information that can be applied to collections decisions in a variety of ways to quantify the impact of library resources to the broader community. 相似文献

In this article, we operationalize identification of mixed racial and ethnic ancestry among adolescents as a latent variable to (a) account for measurement uncertainty, and (b) compare alternative wording formats for racial and ethnic self-categorization in surveys. Two latent variable models were fit to multiple mixed-ancestry indicator data from 1,738 adolescents in New England. The first, a mixture factor model, accounts for the zero-inflated mixture distribution underlying mixed-ancestry identification. Alternatively, a latent class model allows classification distinction between relatively ambiguous versus unambiguous mixed-ancestry responses. Comparison of individual indicators reveals that the Census 2000 survey version estimates higher prevalence of mixed ancestry but is less sensitive to relative certainty of identification than are alternate survey versions (i.e., offering a “mixed” check box option, allowing a written response). Ease of coding and missing data are also considered in discussing the relative merit of individual mixed-ancestry indicators among adolescents. 相似文献

This study examined the utility of Ajzen's () theory of planned behaviour and Maddux's () revised theory of planned behaviour to predict endurance training intentions and adherence of elite junior netball athletes. One hundred and fifteen athletes from the England Netball World Class Start Programme were assessed on constructs central to the predictions of the two theories. Adherence to a recommended endurance training programme was recorded in self-report diaries across a 9-week period. Validity for the diaries was supported by significant correlations (P <?0.001) with recalls across 7 days and 9 weeks. Adherence was moderate and variable between athletes (mean = 66.05, s = 25.75%). Two separate path analyses were conducted to examine the predictions of the theories. Goodness-of-fit indices suggested acceptable fit of the data to the models. Analyses showed that attitude towards the new behaviour, subjective norms and perceived behavioural control predicted training intentions. The relationship between intention and adherence was weak. The present results suggest that the constructs of the theory of planned behaviour offer some insight into the explanation of intentions to follow an endurance training programme. Constructs unique to the revised theory of planned behaviour did not significantly predict training intentions or behaviour. Implications for practitioners working with team sport performers are provided. 相似文献

Doctoral student training has become focused in recent years on acquiring subject-area knowledge and research skills, rather than on teaching. This shift often leaves aspiring junior faculty feeling unprepared to address the demanding pedagogical requirements of the professoriate. In the area of social work, few programs contain a structured, required program of study that addresses issues unique to teaching in a school of social work. This article outlines a doctoral teaching workshop as a model framework for social work doctoral programs. Suggestions are provided for ways to incorporate such an effort into current social work doctoral education. 相似文献

Undergraduate research (UR) is a valued co-curricular activity that has involved an increasing number of students and faculty members in recent years. While there is a growing body of research on student participation in UR, there is less research available examining faculty perceptions of, participation in UR, and how those factors influence student participation in UR. This study examined approximately 110,000 responses to the National Survey of Student Engagement and 40,000 responses to the Faculty Survey of Student Engagement at over 450 four-year institutions. Findings revealed that individual and institutional characteristics predicted student and faculty member involvement and that the majority of faculty members perceived UR to be of importance. Implications for fostering faculty involvement, student success, and viewing UR as an institutional asset are discussed. 相似文献

Much research has focused on student views about physics concepts, with an emphasis on the identification of alternative conceptions, and how curricula and professional development may ameliorate the situation. However, there has been little work on determining the extent of, and in separating, the student and teacher/classroom level variables that may impact student physics achievement. This study examined the effect of different student and teacher/classroom level variables on student understanding of physics concepts using hierarchical linear modeling (HLM), a regression based technique. The data were collected from 68 different teachers and 3,119 students who were using a reform curriculum, Active Physics. Teachers and students completed surveys asking about their beliefs, their classes and their personal characteristics. Students also completed a physics achievement test. The data show that students of teachers who used Active Physics for a greater portion of the year scored higher on the achievement test than did students of teachers who did not use the curriculum as much. Furthermore, the data show that the achievement gap was narrowed between boys and girls and between students with different attitudes toward physics. Additionally teachers who received inservice instruction on how to implement Active Physics narrowed the gap between students with different views of their classroom involvement. © 2009 Wiley Periodicals, Inc.
