Evaluation of a school-to-work internship pilot program for high-school seniors with special needs
No full textStudents with disabilities face a variety of challenges that extend beyond the classroom, as they are often behind their peers in social and life skills. As they exit their secondary education programs they are often ill prepared to meet the multi-dimensional demands of the work place. According to the United States Department of Labor(2011), only 34% of adults with disabilities ages 18–64 years work full time, when compared with 82% of those without disabilities. The current study examined a specialized School-to-Work Internship Pilot Program designed for high school seniors with disabilities that was developed and implemented by a school district in central New Jersey. Twenty four students from the 2009-2010 and 2010-2011 graduating classes participated in this study. Of those 24 participants, 10 participated in the School-to-Work Internship Pilot Programand 14 participated as the matched control group in this quasi-experimental study. Participants reported on their post-high school experiences of employment and post-high school education enrollment. In addition, these participants self-appraised their job knowledge/skills, socialization/emotional coping skills, task flexibility, dependability, motivation, and job satisfactionon a questionnaire pertaining to their employment experiences. These participants also appraised theirlife satisfaction, feelings of competence,empowerment, and social belongingon a questionnaire pertaining to their quality of life. Results indicated that the School-to-Work and Case Control participant groups did not statistically differ with respect to securing or maintaining employment, or the measures of employment experiences or quality of life. However, participants in the School-to-Work group enrolled in post-secondary education at a statistically significant higher rate when compared to the Case Control group. The School-to-Work Internship Pilot Program may have empowered these student participants to gain the necessary insight that further training would be necessary to obtain a full time job that is both rewarding and providesfull time benefits. Furthermore, although there were no statistical group differences due to small sample size, the School-to-Work Internship Pilot Program appeared to have generally positive influences on quality of life for participants as indicated by consistently favorable outcomes.Psy.D.Includes bibliographical referencesby David S.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Human population structure and demographic history using genetic markers
Full text linkThe evolutionary history of the human species has generated complex patterns of population structure and linkage disequilibrium (non-random associations of alleles at different loci or LD). The understanding of these patterns is crucial to two of the most important challenges facing biomedical science today: the identification of disease predisposing genes and prediction of variable drug reactions. The genetic variation revealed by these endeavours can also illuminate the underlying population historical processes. Here, I illustrate each of these applications: first, by assessing the demographic context of cultural change in the British Isles. Y chromosome variation indicates that the Viking age invasions left a significant paternal legacy (at least in Orkney), while the Neolithic and Iron Age cultural transitions did not. In contrast, mitochondrial DNA and X chromosome variation indicate that one or more of these pre-Anglo-Saxon revolutions had a major effect on the maternal genetic heritage of the British Isles. Second, I provide conclusive evidence that diverse demographic histories produce strikingly different patterns of association. Elevated LD extends an order of magnitude further in the Lemba, a Bantu-Semitic hybrid population, than in the putative parental populations. A significant relationship between allele-frequency differentials in the parental populations and the Lemba LD demonstrates that it is admixture-generated. Third, I demonstrate that the genetic structure inferred in a heterogeneous sample using neutral markers (a) shows ethnic labels to be inaccurate descriptions of human population structure, and (b) predicts drug metabolising profiles, defined by the distribution of drug metabolising enzyme variants. Thus the trade-off between therapeutic response and adverse drug reactions will differ between different sub-clusters. Assessment of genetic structure during drug trials is therefore, like the empirical evaluation of each population’s pattern of LD, a necessity
