Factors Associated with Physician Discussion of Health Behaviors with Adolescents

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

Thinking Globally,Integrating Locally: Gender,Entrepreneurship and Urban Citizenship in Germany

Germany's refusal to pursue active integration policies for three decades has unleashed surprising do-it-yourself-integration processes among migrant communities, as demonstrated by dramatic changes in the Turkish ethnic economy since 1990. This study embeds these developments in an analytical framework linking economic enclaves and urban citizenship. Initially motivated by structural unemployment and social exclusion, guestworkers and their offspring are turning to self-employment, not only adding new jobs to an otherwise moribund national economy but also promoting urban revitalization in cities like Berlin, Frankfurt and Cologne. The study outlines generational differences within the Turkish-German community, ascertaining that third-generation ethnics are more likely to start businesses outside the food sector and more willing to embrace FRG citizenship. It describes the size and scope of ethnic enterprises across Germany, followed by a treatment of women entrepreneurs in Berlin. Ethnic associations indirectly foster “participatory” consciousness among males, but women tend to identify directly with the society that offers opportunities not available to them in the purported Turkish homeland. Instead of producing “parallel societies” (as German politicians often insist), ethnic businesses and local community involvement are crucial in bridging majority and minority cultures, on the one hand, and in granting Turkish entrepreneurs top-level access to state policy-makers—even without the formal rights of citizenship.     

A DNA microarray system for forensic SNP analysis

Forensic DNA analysis is routinely performed using polymorphic short tandem repeat (STR) markers. However, for degraded or minute DNA samples, analysis of autosomal single nucleotide polymorphisms (SNPs) in short fragments might be more successful. Furthermore, sequencing of mitochondrial DNA (mtDNA) is often performed on highly degraded or scarce samples due to the high copy number of mtDNA in each cell. Due to the increasing number of complete mtDNA genome sequences available, the limited discrimination power of an mtDNA analysis, may be increased by analysis of coding region polymorphisms in addition to the non-coding variation. Since sequence analysis of the coding region would require more material than generally present in forensic samples, an alternative SNP analysis approach is required. We have developed a one-colour microarray-based SNP detection system for limited forensic materials. The method is based on minisequencing in solution prior to hybridisation to universal tag-arrays. In a first outline of a forensic chip, a combination of 12 nuclear and 21 mitochondrial SNP markers are analysed simultaneously. The mitochondrial markers on the chip are polymorphisms within the hypervariable region as well as in the coding region. Even though the number of markers in the current system is limited, it can easily be extended to yield a greater power of discrimination. When fully developed, microarray analysis provides a promising system for efficient sensitive SNP analysis of forensic samples in the future.     

Y-chromosome STR system, Y-PLEX 12, for forensic casework: development and validation

The Y-PLEX 12 system, developed for use in human identification, enables simultaneous amplification of eleven polymorphic short tandem repeat (STR) loci, namely DYS392, DYS390, DYS385 a/b, DYS393, DYS389I, DYS391, DYS389II, DYS 19, DYS439 and DYS438, residing on the Y chromosome and Amelogenin. Amelogenin provides results for gender identification and serves as internal control for PCR. The validation studies were performed according to the DNA Advisory Board's (DAB) Quality Assurance Standards. The minimal sensitivity of the Y-PLEX 12 system was 0.1 ng of male DNA. The mean stutter values ranged between 3.76-15.72%. A full male profile was observed in mixture samples containing 0.5 ng of male DNA and up to 400 ng of female DNA. Amelogenin did not adversely affect the amplification of Y-STRs in mixture samples containing male and female DNA. The primers for the Y-STR loci present in Y-PLEX 12 are specific for human DNA and some higher primates. None of the primate samples tested provided a complete profile at all 11 Y-STR loci amplified with the Y-PLEX 12 system. Y-PLEX 12 is a sensitive, valid, reliable, and robust multiplex system for forensic analysis, and it can be used in human forensic and male lineage identification cases.     

Side-bets and reciprocity as determinants of organizational commitment among correctional officers

Organizational commitment is a particularly salient characteristic of the prison work climate due to the stressful working conditions and high rate of turnover among correctional officers nationwide, yet little is known about the factors that predict the level of organizational commitment among officers. Becker's (1960) side-bets hypothesis predicts greater commitment among those who develop additional investments in the job that would be lost with a change of jobs, and the reciprocity hypothesis predicts greater commitment among those who feel they are well treated, supported, and respected by the organization. This study used a sample of 546 correctional officers to examine the relative effects of side bets and reciprocity on two components of organizational commitment—affective commitment and continuance commitment. The results of a multivariate OLS regression analysis indicated that reciprocity had a greater effect than side bets on affective commitment but that side bets had a greater effect than reciprocity on continuance commitment. These findings, which provide partial support for the side-bet hypothesis and strong support for the reciprocity hypothesis, are discussed in terms of the link between organizational commitment and other work-related behaviors.     

Legitimacies, Indian Identities, and the Law: The Politics of Sex and the Creation of History in Colonial New England

In an early-eighteenth-century legal contest on Chappaquiddick Island, Massachusetts, an Indian leader, Jacob Seeknout, appealed a ruling that under-mined his political authority. Seeknout's lawyer, Benjamin Hawes, crafted an argument that intertwined the sexual legitimacy of Seeknout's ancestors with his political legitimacy; at the same time, Hawes also linked Indians'collective chastity as a "nation" to their sovereign status. This paper examines the economic, religious, criminal, and historical contexts of this argument, exploring the history of Indians'conjugal practices and their reinvention as the criminal acts of fornication. The case illustrates some of the diverse sources of early American law, links between these legal structures and colonialism, and the importance for scholars of attending to the local level in exploring the power of colonial law to shape new racial identities.
