A study of sex identification of trace, dried bloodstains using a Y-chromosome-specific deoxyribonucleic acid (DNA) probe

A new method is discussed which examines trace, dried bloodstains by gel in situ hybridization using a Y-chromosome-specific deoxyribonucleic acid (DNA) probe to determine the sex of the bloodstain for forensic medicine application. The complete DNA is transferred directly by electrophoresis onto the gel intact, bypassing the possibilities of impurities contaminating the sample and of DNA degradation. The method has proven accurate for small (2.5-mm-diameter) samples aged up to eight years and is quick, simple, and easily read.     

Sex diagnosis of Chinese skulls using multiple stepwise discriminant function analysis.

Sixty Chinese skulls (30 males and 30 females) from Liaoning Province of the People's Republic of China were used in this study. Forty-one variables on each skull were measured and one group of 14 and a second group of 5 variables were selected from all the variables by applying multiple stepwise regression on a computer. Discriminant equations for the 14 and 5 variables for sex diagnosis have been obtained and these variables are highly significant. The discriminant rate for the group of 5 variables resulted in accurate sex determination in 96.7% of cases. For the group of 14 variables there was 100% success rate.     

He Loves Me; He Loves Me Not: Attachment and Separation Resolution of Abused Women

Working within an attachment perspective, we examined women's success at emotional separation from abusive partners. The attachment patterns of 63 abused women were assessed shortly after having left their abusive relationships. Six months later, their perceptions, feelings, and behaviors regarding the separation were assessed, to determine an overall level of separation resolution. As expected, attachment patterns associated with a negative self model were overrepresented (88% of the sample had a predominant pattern of fearful or preoccupied attachment). Further, preoccupation was associated with shorter relationship length, more frequent previous separations from the abusive relationship, continuing emotional involvement with partners after separation, and more frequent sexual contact with partners. These findings suggest that preoccupation may be a risk factor in successful separation resolution from abusive relationships.     

Rising to the Top: Gender,Political Performance,and Party Leadership in Parliamentary Democracies

Party leaders are the main actors controlling campaign strategies, policy agendas, and government formation in advanced parliamentary democracies. Little is known, however, about gender and party leadership. This article examines gendered leadership patterns across 71 political parties in 11 parliamentary democracies between 1965 and 2013. It shows that men and women have different access to, and experiences in, party leadership and that these gendered political opportunity structures are shaped by parties' political performances. Women are more likely to initially come to power in minor opposition parties and those that are losing seat share. Once selected for the position, female leaders are more likely to retain office when their parties gain seats, but they are also more likely to leave the post when faced with an unfavorable trajectory. Together, these results demonstrate that prospective female leaders are playing by a different (and often more demanding) set of rules than their male counterparts.
