The changing association between prenatal participation in WIC and birth outcomes in New York City.

We analyze the relationship between prenatal WIC participation and birth outcomes in New York City from 1988-2001. The analysis is unique for several reasons. First, we have over 800,000 births to women on Medicaid, the largest sample ever used to analyze prenatal participation in WIC. Second, we focus on measures of fetal growth distinct from preterm birth, since there is little clinical support for a link between nutritional supplementation and premature delivery. Third, we restrict the primary analysis to women on Medicaid who have no previous live births and who initiate prenatal care within the first four months of pregnancy. Our goal is to lessen heterogeneity between WIC and non-WIC participants by limiting the sample to highly motivated women who have no experience with WIC from a previous pregnancy. Fourth, we analyze a large sub-sample of twin deliveries. Multifetal pregnancies increase the risk of anemia and fetal growth retardation and thus may benefit more than singletons from nutritional supplementation. We find no relationship between prenatal WIC participation and measures of fetal growth among singletons. We find a modest pattern of association between WIC and fetal growth among U.S.-born Black twins. Our findings suggest that prenatal participation in WIC has had a minimal effect on adverse birth outcomes in New York City.     

Empowerment through group support: Adult women who are survivors of incest

This article describes the need for professional recognition of the magnitude of the problem of incest and the long-term effects on the lives of survivors. It suggests that women can be empowered to make positive lifestyle changes through long-term support. The educational opportunity provided for graduate students is also addressed. The intake process and the three phases of the group which extend over 56 sessions are described in detail.     

The use of DNA stabilizing solution to enable room temperature storage and transportation of buccal and trace sample swabs

It is proposed that a DNA stabilizing solution (DNA Genotek Inc.) designed to preserve DNA in saliva samples at room temperature can be extrapolated to the storage of swab heads. The aim of this study was to evaluate the effectiveness of the solution for the preservation of reference swabs (buccal) and trace samples (facial swabs). To this end, the solution was used during a twin-site DNA transfer project assessing background levels of carer DNA present in children. Tubes containing 400 μl of solution were used to store and transport swab heads. At the laboratory, samples were extracted using the QIAamp DNA Mini Kit (Qiagen), quantified using the Quantifiler Duo Kit and profiled using the AmpF?STR^® SGM Plus^® PCR Amplification Kit (both Applied Biosystems). Twenty-eight PCR cycles were applied to all samples. Thirty-four cycles or a longer electrophoresis injection time was applied to trace samples where necessary. All Reference swabs produced high quantities of DNA and full DNA profiles after 28 cycles. Profile morphology indicated good quality DNA with no degradation. Of the trace samples, sufficient profiles were achieved to study the transfer of carer DNA making the solution fit for continued use in this project. DNA stabilizing solution enables the storage and transportation of swabs without freezing. This is convenient, reduces transportation costs and enables instant analysis of samples upon arrival at the laboratory. This is a useful alternative for a multi-site research project as well as a reliable storage tool for use in remote areas.     

Computer‐aided Dental Identification: An Objective Method for Assessment of Radiographic Image Similarity*

Abstract: A pilot study evaluated a computer‐based method for comparing digital dental images, utilizing a registration algorithm to correct for variations in projection geometry between images prior to a subtraction analysis. A numerical assessment of similarity was generated for pairs of images. Using well‐controlled laboratory settings, the method was evaluated as to its ability to identify the correct specimen with positive results. A subsequent clinical study examined longitudinal radiographic examinations of selected anatomical areas on 47 patients, analyzing the computer‐based method in making the correct identification based upon a threshold level of similarity. The results showed that at a threshold of 0.855, there were two false negative and two false positive identifications out of 957 analyses. Based on these initial findings, 25 dental records having two sets of full mouth series of radiographs were selected. The radiographs were digitized and grouped into six anatomical regions. The more recent set of films served as postmortem images. Each postmortem image was analyzed against all other images within the region. Images were registered to correct for differences in projection geometry prior to analysis. An area of interest was selected to assess image similarity. Analysis of variance was used to determine that there was a significant difference between images from the same individual and those from different individuals. Results showed that the threshold level of concordance will vary with the anatomical region of the mouth examined. This method may provide the most objective and reliable method for postmortem dental identification using intra‐oral images.     

Cognitive Abilities,Social Adaptation,and Externalizing Behavior Problems in Childhood and Adolescence: Specific Cascade Effects Across Development

Children’s and adolescents’ cognitive abilities, social adaptation, and externalizing behaviors are broadly associated with each other at the bivariate level; however, the direction, ordering, and uniqueness of these associations have yet to be identified. Developmental cascade models are particularly well-suited to (1) discern unique pathways among psychological domains and (2) model stability in and covariation among constructs, allowing for conservative tests of longitudinal associations. The current study aimed to identify specific cascade effects among children’s cognitive abilities, social adaptation, and externalizing behaviors, beginning in preschool and extending through adolescence. Children (46.2?% female) and mothers (N?=?351 families) provided data when children were 4, 10, and 14 years old. Cascade effects highlighted significant stability in these domains. Unique longitudinal associations were identified between (1) age-10 cognitive abilities and age-14 social adaptation, (2) age-4 social adaptation and age-10 externalizing behavior, and (3) age-10 externalizing behavior and age-14 social adaptation. These findings suggest that children’s social adaptation in preschool and externalizing behavior in middle childhood may be ideal intervention targets to enhance adolescent well-being.     

Reflections on “The Politics of Informality”: What We Know,How We Got There,and Where We Might Head Next

Building on the methodological and empirical contributions of the various authors in this special symposium, this concluding reflection acknowledges the important role that informality plays in urban and national politics in the global South, even as it proposes a range of alternative ways, this critical topic could and should be inserted into contemporary scholarship in comparative politics. It begins with a discussion of two decades of research on urbanization and economic globalization, thus introducing a wider set of disciplinary concerns than merely urban servicing into the study of informality, ranging from the transformation of property rights regimes in the context of ascendant neo-liberalization to the recent emergence of more decentralized political structures for claim-making and governance. The essay then suggests that greater historical and contextual specificity in the study of informality, along with the methodological innovations highlighted in the papers, will further help reveal the range of responses to informality seen across the different case studies. Specifically, it proposes that closer attention to divergent urban and national pathways of democratization, attention to institutional variations within and across democratic regimes, political party dynamics at the local and national level, and the existence of urban violence, among other factors, will help explain how and why bureaucrats and elected officials may choose to deal differently with the existence of informality. The essay concludes by arguing that informality should be considered as both a form of governance and a means of enacting citizenship. It thus asks scholars to question the longstanding conceptual dichotomies that permeate much of the literature on informality, including the stark conceptual divide between the formal and informal, and instead to recognize that complex, interactive, and iterative relationships between citizens and the state in the arena of informality are what drive urban servicing and sociopolitical change.     

Lesbian,Gay and Bisexual Populations: The Role of English Local Government

Abstract

The role of local government has recently come under debate, in the context of state retrenchment, public sector cuts and the marketisation of welfare. Recent discussions have centred on local authorities as leaders, on enterprise and on democracy, but there has been little discussion of local authorities in relation to equalities issues and minority groups. This article examines the role of local government in relation to one minority grouping, Lesbian, Gay and Bisexual (LGB) people, drawing on empirical material gathered from 2007 to 2010 as part of a large Economic and Social Research Council research project. It describes the importance of equalities legislation and related implementation mechanisms in driving forward the LGB equalities agenda, explores aspects of welfare delivery to LGB people and addresses democratic processes. The article suggests that a collision of different forces is currently taking place: the legislation supports the protection of the LGB communities, but this support is undermined by the recession-related and ideologically driven public sector cuts. In addition, aggregate approaches to local democracy may override the interests of minority groups such as LGB people.
