Utility of the Y-STR typing systems Y-PLEX 6 and Y-PLEX 5 in forensic casework and 11 Y-STR haplotype database for three major population groups in the United States

The Y-PLEX 6 and Y-PLEX 5 systems enable analysis for 11 Y-STR loci. We present here the utility of these systems in forensic casework. A total of 188 samples, including 127 evidence samples, were analyzed using either or both of the systems. The evidence sample types included fingernail scrapings, sperm or seminal fluid, epithelial cells, blood and other tissues. The Y-STR typing systems provided useful probative results in difficult cases. A reference database for Caucasian (n = 517), African American (n = 535), and Hispanic (n = 245) population groups within the United States was generated for estimating the haplotype frequency in forensic casework. Among the individuals profiled, 311 Caucasians, 412 African Americans, and 194 Hispanics provided unique profiles in their respective population datasets. This is the first report describing the haplotype database for the set of 11 Y-STR loci recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Linkage analysis reveals that the frequencies from forensically important autosomal loci can be multiplied with the Y-STR haplotype frequency. The results from Y-PLEX systems have been accepted in courts in the United States.     

Statutory Protection for Renters: Classification of State Landlord–Tenant Policy Approaches

There are many federal, state, and local laws governing the landlord–tenant relationship. Yet scholars know little about their variety and what impact differences among jurisdictions have on renters and rental housing markets. This article examines state-level landlord–tenant policy approaches to determine whether there is significant policy variation and whether states illustrate identifiable policy types. Using cluster and discriminant analysis, this research creates a typology of landlord–tenant policy approaches, finding three distinctive approaches: protectionist, probusiness, and contradictory. This research indicates there is significant variation among state landlord–tenant statutory policies, although states’ laws generally reflect one of three philosophies. These results are important for future studies on rental housing because treating all state rental environments the same masks important differences in rental experiences across states. As an illustration, this article finds that renters in protectionist and contradictory states move significantly more than renters in probusiness states do. Furthermore, understanding where renters have more or less legal protection allows policymakers and advocates to focus their efforts on areas where assistance is most needed.     

Adolescents’ Judgment of Homophobic Name-Calling: The Role of Peer/Friend Context and Emotional Response

Journal of Youth and Adolescence - Adolescents use some types of homophobic language (e.g., “that’s so gay”) as a form of banter, while other types are directly targeted as an...     

A Song of Policy Incongruence: The Missing Choir of Consumer Preferences in GMO‐Labeling Policy Outcomes

This article focuses on the degree of policy congruence, and by extension policy responsiveness, of U.S. federal‐ and state‐level GMO labeling laws from 2011–2016. Utilizing consumer survey data, evidence overwhelmingly demonstrates consumers prefer clear text‐based indication if food products contain genetically modified ingredients. However, the federal law adopted in 2016 mandates GMO labeling but with exceptions permitted to clear on‐package text labeling. The results of this study demonstrate that consumer preferences were not adequately represented at the federal level and were misaligned with state policy activities as captured in the aggregate outcome. State legislatures were actively proposing mandatory legislation with only a few cases of success, which did not adequately represent the wishes of the people. Given the misalignment and overall policy incongruence, the consequences of pending federal law are discussed in light of why the voices of the consumer choir were not heard by lawmakers.     

The Broader Context of Relational Aggression in Adolescent Romantic Relationships: Predictions from Peer Pressure and Links to Psychosocial Functioning

The broader context of relational aggression in adolescent romantic relationships was assessed by considering the ways such aggression emerged from prior experiences of peer pressure and was linked to concurrent difficulties in psychosocial functioning. Longitudinal, multi-reporter data were obtained from 97 adolescents and their best friends at age 15 and from adolescents and their romantic partners at age 18. Teens’ relational aggression and romantic partners’ victimization were predicted from levels of best friends’ pressuring behaviors toward teens in an observed interaction as well as from best friends’ ratings of how much pressure teens experienced from their peer group. Romantic partner relational aggression and teen victimization were predicted by pressure from teens’ peer group only. Adolescents’ romantic relational aggression and victimization were also associated with elevated levels of depressive symptoms and increased alcohol use. Results are discussed in terms of the connection of relational aggression in romantic relationships to the broader task of establishing autonomy with peers in psychosocial development.

Sibling violence and agonistic interactions experienced by early adolescents

Negative physical and verbal interactions occurring between early adolescents and their closest-spaced sibling were examined. Two hundred forty-four junior high school students provided information concerning their experiences as victims and perpetrators of aggressive and agonistic behaviors. Results confirm earlier studies' findings that siblings engage in numerous hostile interactions and that females and males perform these behaviors to an almost equal extent. Participants' self-reports suggest that parents may underestimate sibling use of physical force to resolve conflicts. Findings indicate there is further need to examine sibling interactions in order to better understand family functioning and family violence.
