Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

“I Just Want To Play”: Women, Sexism, and Persistence in Golf

Golf does not inherently privilege men or women physically, yet men are much more likely to participate in golf. The authors explore the institutional (e.g., societal level) and interactional barriers to women’s golf participation and uncover strategies women use to negotiate playing and persisting in golf. Guided by research on tokenism in occupations, statistical discrimination, and feminist research in the sociology of sport, the authors use 10 interviews with recreational women golfers to explore these issues. Similar to women in predominantly male occupations, the women in this study report heightened visibility and experiences with typecasting on the golf course. In addition, social closure operates in the form of unwelcoming courses; women reported feeling ignored, overlooked, or unimportant on the course. The authors discuss several strategies the women in the sample use to overcome sexism and persist in golf

Gender, Social Bonds, and Delinquency: A Comparison of Boys’ and Girls’ Models

Past research has assessed gender differences in delinquency due to differential social controls, yet important questions remain regarding gender and social bonding. As much of this work was premised on Hirschi’s measurement of the social bond, we examine whether gender moderates two parts of the social bond: the measurement of the social bond and structural differences between the social bond and delinquency. Using multiple-group structural equation modeling, we find that neither the measures of the social bond nor their relationships with property crime are gender-specific. The structural relationship between the elements of the social bond and violent delinquency differs slightly for boys and girls. We discuss implications of this research for social control theory, measuring the social bond and for gender-specific theories of social bonding and control

Sex differences in the causes of self-control: An examination of mediation, moderation, and gendered etiologies

Sex is one of the most robust predictors of self-control, with a consistent finding that girls score higher on a variety of measures of self-control. In this research, we investigate three possible reasons for why this is true: first, we examine whether current predictors of self-control mediate the effect of sex on self-control, second, we examine whether sex moderates the effect of current predictors on self-control and third, we examine the possibility that the causes of self-control are gendered, necessitating different causal models for boys and girls. Using data from the Children of the National Longitudinal Survey of Youth79, we assess three, related questions: Is the sex effect on self-control mediated by current predictors of self-control? Does sex moderate the effects of current predictors of self-control? Does the causal model predicting self-control differ for boys and girls? We find that the sex effect on self-control is robust; does not moderate the etiology of self-control; and although partially mediated by etiological variables, remains a significant predictor of self-control. We also find that current predictors do a poor job of explaining girls' acquisition of self-control, suggesting a gendered etiology of self-control.

Child Neglect and Adolescent Violence: Examining the Effects of Self-Control and Peer Rejection

Child maltreatment researchers have often suggested that experiences with child neglect have long-term, negative effects. Child neglect is thought to have particularly adverse effects on self-control, peer relations, and delinquency. In this research, we examine the relationship of child neglect with adolescent violence via self-control and peer rejection. Using prospective, longitudinal data from a community sample, we find that child neglect adversely affects peer rejection and violence. Neglected children were more likely to be rejected by their peers in early adolescence and were more likely to be violent later in adolescence. Contrary to theoretical predictions, child neglect was not a significant predictor of self-control. Implications for delinquency and child maltreatment researchers are discussed
