Those entering the world of publishing standards for the first time may find it a baffling alphabet soup—with NISO, ANSI,
BISG, IEEE, NIST, and ANSC floating on a broth bubbling with activity. Jacob and Rings sort out the acronyms, explaining what
each of these groups does and how they interact.
Mary Ellen L. Jacob, vice president for library planning at OCLC, is responsible for strategic planning activities regarding
libraries and library services. Mrs. Jacob is also the board chair of the National Information Standards Committee.
Deborah L. Rings, information analyst for library planning at OCLC, is responsible for identifying trends and factors relative
to the library and information science areas, and for assessing their impact and potential impact on OCLC and its strategic
planning processes. 相似文献

This paper describes the sexual socialisation process of marginalised, drug-using heterosexual black men, focusing primarily on the sources and content of sexual information. Analysing qualitative interview data, we discovered that the men in our sample both learn about sex and become sexually active at an early age. They most often learn about sex from the media and least often learn about sex from family members. The content of sexual information varies in specifics, but overall tends to equate sex with pleasure, encourage sexual activity with multiple partners and emphasise using protection. Our goal is to use this data to better understand how sexual socialisation contributes to the prevalence of multiple sexual partners and high rates of HIV among heterosexual black men in order to inform future risk-reduction intervention programmes. 相似文献

This article assesses the quality of 12 American doctoral programs by counting the number of publications of their Ph.D. graduates in a large number of criminology and criminal justice journals, and in 20 more “academic” journals. While half of the Ph.D. graduates had no publications, the 4 percent who were the most productive (the “stars”) accounted for one third of all journal articles. Publication rates up to graduation predicted publication rates after graduation. The University of Maryland, Michigan State University, the University of California at Irvine, Florida State University, and Sam Houston State University had the most productive Ph.D. graduates in academic journals. There was a significant correlation between the productivity of a program's Ph.D. graduates and the productivity of its faculty members. The academic publication rate was influenced most by prevalence (the percentage of Ph.D.s with at least one publication), rather than by the percentage of “stars” or the frequency of publications. 相似文献

This article examines one university's policies regarding Native mascots and ethnic fraud through a Tribal Critical Race Theory analytic lens. Using the principle of interest convergence, we argue that institutions of higher education allow and even work actively towards a particular form or level of diversity, but they do not extend it far enough. Once racial remedies no longer hold value or benefit the institution itself, the status quo is maintained. Ultimately, the university has an interest in “celebrating” diversity and supporting superficial multiculturalism, but it does not have an interest in critical, social justice-oriented policies that challenge the status quo, the current racial order, or the institution's privilege and power. 相似文献

Four methods for estimating a dynamic factor model, the direct autoregressive factor score (DAFS) model, are evaluated and compared. The first method estimates the DAFS model using a Kalman filter algorithm based on its state space model representation. The second one employs the maximum likelihood estimation method based on the construction of a block-Toeplitz covariance matrix in the structural equation modeling framework. The third method is built in the Bayesian framework and implemented using Gibbs sampling. The fourth is the least squares method, which also employs the block-Toeplitz matrix. All 4 methods are implemented in currently available software. The simulation study shows that all 4 methods reach appropriate parameter estimates with comparable precision. Differences among the 4 estimation methods and related software are discussed. 相似文献

Effects of prenatal cocaine exposure and parental versus nonparental care on outcome at 2 years of age were examined. The sample included 83 cocaine-exposed and 63 nonexposed children and their caregivers; 49 and 34 of the cocaine-exposed children experienced parental and nonparental care, respectively. Prenatal drug exposure was not related directly to children's outcome at 2 years of age. However, compared with cocaine-exposed children in parental care, those in nonparental care experienced a more optimal environment and performed better in several developmental domains at 2 years of age in spite of being at greater neonatal risk. Further analyses suggested that this protective effect of nonparental care was in part due to nonkin rather than kin care. 相似文献

Research on factors that shape recruitment and retention in undergraduate science majors currently is highly fragmented and in need of an integrative research framework. Such a framework should incorporate analyses of the various levels of organization that characterize academic communities (i.e., the broad institutional level, the departmental level, and the student level), and should also provide ways to study the interactions occurring within and between these structural levels. We propose that academic communities are analogous to ecosystems, and that the research paradigms of modern community ecology can provide the necessary framework, as well as new and innovative approaches to a very complex area. This article also presents the results of a pilot study that demonstrates the promise of this approach at the student level. We administered a questionnaire based on expectancy-value theory to undergraduates enrolled in introductory biology courses. Itself an integrative approach, expectancy-value theory views achievement-related behavior as a joint function of the person's expectancy of success in the behavior and the subjective value placed on such success. Our results indicated: (a) significant gender differences in the underlying factor structures of expectations and values related to the discipline of biology, (b) expectancy-value factors significantly distinguished biology majors from nonmajors, and (c) expectancy-value factors significantly predicted students' intent to enroll in future biology courses. We explore the expectancy-value framework as an operationally integrative framework in our ecological model for studying academic communities, especially in the context of assessing the underrepresentation of women and minorities in the sciences. Future research directions as well as practical implications are also discussed. 相似文献
