Three essays on the impact of child custody law on child educational attainment
Get PDFI examine in this thesis the impact changes in Child Custody Law can have on children of differing family structures in terms of their educational attainment, and intergenerational educational mobility conditional on parental educational attainment and income. I then explore a possible theoretical explanation for these effects. Chapters 2 and 3 studies the empirical impact of the regime shift from maternal preference to joint custody in custody dispute adjudication in the United States during the 1980s using the one percent Integrated Public Use Microsample Series (IPUMS) of the decennial Census for the decades from 1970 to 1990. Focusing on children between the ages of 15 to 18 who were living with a single divorced and separated parent and of intact families, I found first using cross state and year variation in the timing of adoption of those laws that the children of single parent households living in states which adopted joint custody had a higher probability of high school graduation at age 18. However, children from intact families suffered a decrease in the same probability. This suggests that the law has important unintended negative effects that had thus far been neglected in the literature. The results were robust to the use of the IPUMS Current Population Survey Sample, and Stochastic Dominance Tests. Next using a new distributional overlap measure I found evidence of reduction in alienation between children of intact and single parent families, and particularly between divorced and separated parent families compared with children of widowed parents. This accords with intuition since widowed parent households would not have been affected by the changes in family law. In general, there seem to be a move towards greater intergenerational mobility as a result of joint custody law adoption. In Chapter 4, I model familial choices in labor supply and investments in the quality of children in the shadow of evolving child custody legislations, from the perspective of differential fecundity. The model is able to explain why child support payment rose with joint custody law adoption, and emphasizes the impact the law can have on equilibrium marriage, remarriage and divorce rates.Ph.D
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
