    Introduction: federalism in an era of globalisation

    INTERNATIONAL SOCIAL SCIENCE JOURNAL, Issue 167 2001
    Ronald Watts
    Under the pressure of globalization we appear to be in the midst of a paradigm shift from a world of nation-states to one in which federalism provides the closest political approximation to the complex diversity of the contemporaryworld. In this context the Forum of Federations, as its first major activity, held an international conference at Mont Tremblant, Quebec, 5-8 October 1999, on ,Federalism in an Era of Globalization'. The articles in this issue of the International Social Science Journal are drawn from among the many presentations and back-ground papers at that conference, and provide an insight into a range of salient issues within contemporary federations.

    Differentially expressed genes during bovine intramuscular adipocyte differentiation profiled by serial analysis of gene expression

    ANIMAL GENETICS, Issue 4 2010
    Y. Mizoguchi
    Summary Beef marbling or intramuscular fat deposition is an economically important carcass trait in Japanese Black cattle. To investigate genes involved in intramuscular adipogenesis, differential gene expression during adipogenesis in a clonal bovine intramuscular preadipocyte (BIP) cell line was profiled with serial analysis of gene expression (SAGE). We sequenced 75 283 tags for the proliferation phase (day 0) and 81 878 tags for the differentiation phase (4 days after adipogenic stimulation: day 4). A comparison of the unique SAGE tag frequencies between the day 0- and day 4-libraries revealed that 878 (2.8%) of the 30 989 unique putative transcripts were expressed at significantly different levels (P < 0.05); 401 tags (1.4%) were up-regulated and 477 tags (1.2%) were down-regulated in the day 4-library relative to the day 0-library. We confirmed up-regulation of 10 tags of the genes that were up-regulated in the previous subtraction cloning studies in BIP cells [Animal Science Journal, 76 (2005) 479]. Of the 878 differentially expressed tags, 377 were identified in the bovine RefSeq library and 356 were assigned a bovine draft genomic sequence. Fifteen tags were mapped in previously detected beef marbling quantitative trait loci (QTL) regions [Mammalian Genome, 18 (2007) 125]. These genes may be involved in the adipogenic processes of beef marbling. [source]

    A Weak Embrace: Popular and Scholarly Depictions of Single-Parent Families, 1900 , 1998

    JOURNAL OF MARRIAGE AND FAMILY, Issue 2 2009
    Margaret L. Usdansky
    The growth of single-parent families constitutes one of the most dramatic and most studied social changes of the 20th century. Evolving attitudes toward these families have received less attention. This paper explores depictions of these families in representative samples of popular magazine (N = 474) and social science journal (N = 202) articles. Critical depictions of divorce plummeted between 1900 and 1998, a trend stemming not from any increase in favorable depictions but from the virtual disappearance of normative debate. Such de facto acceptance did not extend to nonmarital childbearing, however, depictions of which were almost as likely to be critical at the century's end as at its beginning. These trends illustrate Americans' ambivalent embrace of single-parent families as a reality but not an ideal. [source]

    Theorizing in Family Gerontology: New Opportunities for Research and Practice

    FAMILY RELATIONS, Issue 5 2006
    Karen A. Roberto
    Abstract: We examine the extent to which theory has been used in empirical studies of families in later life, identify prevalent types of theoretical frameworks, and assess connections between theory and both focal topics and analytic methods in the family gerontology literature. The paper is based on content and methodological analysis of 838 empirical articles with a family-level focus published in 13 social science journals during the 1990s. Approximately one half of the articles included theory, with micro-interpretive (social psychological) theories being used most often to guide and inform research and practice. To advance the field and understand better the intricacies of family life among older adults, we suggest that investigators and practitioners explicitly incorporate theoretical frameworks into their endeavors.

    Making subjective judgments in quantitative studies: The importance of using effect sizes and confidence intervals

    HUMAN RESOURCE DEVELOPMENT QUARTERLY, Issue 2 2006
    Jamie L. Callahan
    At least twenty-three journals in the social sciences purportedly require authors to report effect sizes and, to a much lesser extent, confidence intervals; yet these requirements are rarely clear in the information for contributors. This article reviews some of the literature criticizing the exclusive use of null hypothesis significance testing (NHST) and briefly highlights the state of NHST reporting in social science journals, including Human Resource Development Quarterly. Included are an overview of effect sizes and confidence intervals,their definitions, a brief historical review, and an argument regarding their importance. The article concludes with recommendations for changing the culture of quantitative research within human resource development (HRD) to more systematically reporting effect sizes and confidence intervals as supplements to NHST findings.

    Examination of the analytic quality of behavioral health randomized clinical trials

    JOURNAL OF CLINICAL PSYCHOLOGY, Issue 1 2007
    Bonnie Spring
    Adoption of evidence-based practice (EBP) policy has implications for clinicians and researchers alike. In fields that have already adopted EBP, evidence-based practice guidelines derive from systematic reviews of research evidence. Ultimately, such guidelines serve as tools used by practitioners. Systematic reviews of treatment efficacy and effectiveness reserve their strongest endorsements for treatments that are supported by high-quality randomized clinical trials (RCTs). It is unknown how well RCTs reported in behavioral science journals fare compared to quality standards set forth in fields that pioneered the evidence-based movement. We compared analytic quality features of all behavioral health RCTs (n = 73) published in three leading behavioral journals and two leading medical journals between January 2000 and July 2003. A behavioral health trial was operationalized as one employing a behavioral treatment modality to prevent or treat an acute or chronic physical disease or condition. Findings revealed areas of weakness in analytic aspects of the behavioral health RCTs reported in both sets of journals. Weaknesses were more pronounced in behavioral journals. The authors offer recommendations for improving the analytic quality of behavioral health RCTs to ensure that evidence about behavioral treatments is highly weighted in systematic reviews. © 2006 Wiley Periodicals, Inc.

    Link decay in leading information science journals

    JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 1 2007
    Dion Hoe-Lian Goh
    Web citations have become common in scholarly publications as the amount of online literature increases. Yet, such links are not persistent and many decay over time, causing accessibility problems for readers. The present study investigates the link decay phenomenon in three leading information science journals. Articles spanning a period of 7 years (1997,2003) were downloaded, and their links were extracted. From these, a measure of link decay, the half-life, was computed to be approximately 5 years, which compares favorably against other disciplines (1.4,4.8 years). The study also investigated types of link accessibility errors encountered as well as examined characteristics of links that may be associated with decay. It was found that approximately 31% of all citations were not accessible during the time of testing, and the majority of errors were due to missing content (HTTP Error Code 404). Citations from the edu domain were also found to have the highest failure rates of 36% when compared with other popular top-level domains. Results indicate that link decay is a problem that cannot be ignored, and implications for journal authors and readers are discussed. [source]

    Comparative Journal Ratings: A Survey Report

    POLITICAL STUDIES REVIEW, Issue 1 2009
    Iain McLean
    The expert survey and bibliometric methods of assessing the quality of work in political science are complementary. This project builds on previous surveys of academic political science journals conducted among US political scientists. The current wave extends the survey to political scientists in Canada and the UK. Preliminary results suggest both similarities and differences across the three countries. These results matter for policy debate in any country that is considering channelling flows of funds to universities in proportion to the quality of their research, and in helping to supply objective evidence about the research quality of work submitted by candidates for academic appointments and promotions.

    A Global Ranking of Political Science Departments

    POLITICAL STUDIES REVIEW, Issue 3 2004
    Simon Hix
    Rankings of academic institutions are key information tools for universities, funding agencies, students and faculty. The main method for ranking departments in political science, through peer evaluations, is subjective, biased towards established institutions, and costly in terms of time and money. The alternative method, based on supposedly ,objective' measures of outputs in scientific journals, has thus far only been applied narrowly in political science, using publications in a small number of US-based journals. An alternative method is proposed in this paper , that of ranking departments based on the quantity and impact of their publications in the 63 main political science journals in a given five-year period. The result is a series of global and easily updatable rankings that compare well with results produced by applying a similar method in economics. [source]

    Quality of protein crystal structures

    ACTA CRYSTALLOGRAPHICA SECTION D, Issue 9 2007
    Eric N. Brown
    The genomics era has seen the propagation of numerous databases containing easily accessible data that are routinely used by investigators to interpret results and generate new ideas. Most investigators consider data extracted from scientific databases to be error-free. However, data generated by all experimental techniques contain errors and some, including the coordinates in the Protein Data Bank (PDB), also integrate the subjective interpretations of experimentalists. This paper explores the determinants of protein structure quality metrics used routinely by protein crystallographers. These metrics are available for most structures in the database, including the R factor, Rfree, real-space correlation coefficient, Ramachandran violations etc. All structures in the PDB were analyzed for their overall quality based on nine different quality metrics. Multivariate statistical analysis revealed that while technological improvements have increased the number of structures determined, the overall quality of structures has remained constant. The quality of structures deposited by structural genomics initiatives are generally better than the quality of structures from individual investigator laboratories. The most striking result is the association between structure quality and the journal in which the structure was first published. The worst offenders are the apparently high-impact general science journals. The rush to publish high-impact work in the competitive atmosphere may have led to the proliferation of poor-quality structures. [source]
