Genetic polymorphism of 17 STR loci for forensic use in Chinese population from Shanghai in East China

Allele frequencies for 17 STR loci found in Identifier kit and PowerPlex^®16 Monoplex System were determined in a sample of 1000 unrelated individuals living in Shanghai in East China. The values of observed heterozygosity (Ho), power of discrimination (PD), probability of paternity exclusion (PE) and polymorphism information content (PIC) were calculated. All loci were in accordance with Hardy–Weinberg equilibrium (p < 0.05). The obtained frequency distributions were compared with other previously reported population data.     

Are There Gender Differences in Sustaining Dating Violence? An Examination of Frequency, Severity, and Relationship Satisfaction

One topic of debate within the field of intimate violence involves the equivalence, or lack thereof, of male-perpetrated versus female-perpetrated violence. To inform this debate, we examined potential gender-related differences in the frequency of sustaining violence, the severity of violence sustained, and effects of violence on relationship satisfaction. Data were collected from 2 samples of heterosexual undergraduates in dating relationships. In both studies, men and women experienced violence at comparable frequencies, although men experienced more frequent moderate violence. Rates of severe violence were extremely low for both sexes across studies. In both investigations, only women experienced lower relationship satisfaction as a function of partner violence. In Study 1, relationship status moderated this effect, such that women in serious dating relationships were less satisfied than either women in less serious relationships or than men as a function of partner violence. In Study 2, women were less satisfied with violent relationships than men regardless of relationship status. We contend that gender-sensitive approaches to relationship violence are important to better understand and prevent both male- and female-perpetrated violence. Directions for future research efforts are outlined.

Slips and falls in stores and malls: Implications for community‐based injury prevention

An empirical analysis of the behavioral ecology of slip, trip, and fall accidents in grocery stores and shopping malls is presented. The store data set comprised 36 consecutive months of data collected from a chain of grocery stores in the Midwestern USA and the mall data set included 24 consecutive months of data collected from 22 malls across the continental USA, with a concentration in the southern region. Analyses showed that the majority of the slip, trip and fall accidents occurred on the inside of the establishments, on the same level, and resulted from a water or liquid spill or food item on the floor. Design deficiencies accounted for the least amount of occurrences and cost of the accidents, while housekeeping and inspection deficiencies accounted for the bulk of the accidents. Data‐based recommendations for slip, trip and fall injury‐prevention strategies in these public places, focusing on management action, are offered.     

Evaluation of 96 SNPs in 14 populations for worldwide individual identification

Great advances have been made recently in searching for individual identification single-nucleotide polymorphisms (IISNPs or IDSNPs). Such SNPs as suggested by SNPforID scientists and by Pakstis et al., are promising, although they were selected from older or smaller databases rather than the most recent database. Here, we describe a new computational strategy for developing IDSNPs based on HapMap. We searched through HapMap r27 for SNPs having minor allele frequencies ≥0.30 in all its 11 populations and found more than 1881 qualified SNPs. We examined 96 of them with 183 DNA samples from three Chinese populations using Illumina arrays. The average allele frequency for these 96 SNPs among the three populations was 0.495/0.505, the average number of identical SNP genotypes shared by two individuals among the 14 populations (three Chinese and 11 HapMap) was 37.9, and the random matching probability for two unrelated Hans to match in all 96 genotypes was 9.793 × 10(-39). Thus, most of these 96 SNPs are universally applicable.
