Results of the 2018 Rapid DNA Maturity Assessment

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200.     

Measuring Neoliberalism: Development and Initial Validation of a Scale of Anti-Neoliberal Attitudes

Critics of neoliberalism argue that so-called meritocratic and identity-neutral social policies and political positions actually reinforce and exacerbate intersecting inequalities, namely racism, sexism, heterosexism, classism, and ethnocentrism/xenophobia. The purpose of these studies was to develop and initially validate a scale of neoliberal attitudes from a wide range of existing instruments that reflect anti-neoliberal theory. A series of three studies resulted in a 25-item instrument—the Anti-Neoliberal Attitudes Scale (ANAS)—that exhibits initial evidence of construct validity, internal consistency, and test–retest reliability. Exploratory factor analysis with students from two universities revealed a four-factor structure of Racism and Sexism Awareness, Communitarian Values, Multicultural Ideology, and Inequality Consciousness. However, a confirmatory factor analysis with an independent sample of undergraduate students suggests a bifactor model in which the general factor explains most of the variance and that the instrument should be treated as a single scale, rather than independent subscales. Significant correlations with measures of right-wing authoritarianism and social dominance orientation suggest convergent validity. Temporal stability was established via a test–retest analysis in an independent sample of undergraduate students. Finally, responses from a sample of MTurk workers provided evidence of the ANAS’s incremental validity when compared to an existing measure of neoliberal beliefs. Implications for future empirical work on the psychological dimensions of neoliberalism are discussed.

     

Older Siblings as Academic Socialization Agents for Younger Siblings: Developmental Pathways across Adolescence

The role of older siblings in younger siblings’ academic socialization becomes increasingly salient during adolescence. This longitudinal study examines the developmental mechanisms through which older siblings shape younger siblings’ academic outcomes and whether older siblings’ peer affiliations predict younger siblings’ educational aspirations and attainment. Data consisted of responses from 395 target adolescents (M_age?=?12.22 years, 48.9% female; 51.6% African American, 38.5% European American) and their older siblings (M_age?=?14.65 years, 50.1% female) across nine years. The findings showed that older siblings’ affiliation with academically disengaged peers at 7th grade predicted younger siblings’ decreased affiliation with academically engaged peers and increased affiliation with disengaged peers at 9th grade. In addition, younger siblings’ affiliation with academically engaged peers predicted greater educational aspirations at 11th grade, which in turn were related to higher postsecondary educational attainment. The identification of developmental processes through which older siblings were associated with younger siblings’ academic success may aid in creating supportive social environments in which adolescents can thrive.

     

Linking Social Anxiety and Adolescent Romantic Relationship Functioning: Indirect Effects and the Importance of Peers

Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5 % female, 14–19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships.     

’Not Septimus Now‘: wives of disabled veterans and cultural memory of the First World War in Britain

Much of the writing on gender and the First World War has looked at the ways in which pre-war gender norms were reasserted in British society after the War. The article looks at the experiences of one group of women, the wives of men psychologically disabled by the experience of war, to show how disability could prevent the reassertion of pre-war gender roles. The experiences of these women, as expressed in the disability files created by the Ministry of Pensions, is then compared with the dramatisations of wives of disabled veterans in two post-war novels. This comparison highlights the ways in which such dramatisations turned the figure of the wife of the disabled veteran into a symbol of suffering that may be compared to the similarly symbolic figures of the neurasthenic veteran.     

Speaking ‘unspeakable things’: documenting digital feminist responses to rape culture

Abstract

This paper examines the ways in which girls and women are using digital media platforms to challenge the rape culture they experience in their everyday lives; including street harassment, sexual assault, and the policing of the body and clothing in school settings. Focusing on three international cases, including the anti-street harassment site Hollaback!, the hashtag #BeenRapedNeverReported, and interviews with teenage Twitter activists, the paper asks: What experiences of harassment, misogyny and rape culture are girls and women responding to? How are girls and women using digital media technologies to document experiences of sexual violence, harassment, and sexism? And, why are girls and women choosing to mobilize digital media technologies in such a way? Employing an approach that includes ethnographic methods such as semi-structured interviews, content analysis, discursive textual analysis, and affect theories, we detail a range of ways that women and girls are using social media platforms to speak about, and thus make visible, experiences of rape culture. We argue that this digital mediation enables new connections previously unavailable to girls and women, allowing them to redraw the boundaries between themselves and others.     

Vegan men and hybrid masculinity

If eating meat is equated with ‘masculine traits’ of emotional stoicism, strength and virility, do vegan men threaten the concept of a stoic and domineering view of hegemonic masculinity? This research explores how 20 vegan men explain veganism in relation to patriarchal, hegemonic masculinity. We argue that vegan men engage in hybrid masculinity by modifying values associated with veganism and femininity to align with traditional masculine standards. By doing so, vegan men contest the narrow definition of hegemonic masculinity but fall short of challenging gender inequalities.     

Longitudinal Bi-directional Relationships Between Sleep and Youth Substance Use

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.     

Dimensions of Conscience in Mid-adolescence: Links with Social Behavior, Parenting, and Temperament

The purpose of this study was to determine whether aspects of conscience cohere into broader dimensions and to examine how these broader dimensions of conscience relate to parenting, temperament, and social behavior. One hundred and thirteen adolescents (M age = 15.88 years, 51% female) completed measures of sympathy, guilt, empathic anger, shame, moral reasoning, and internalization. Factor analyses revealed two dimensions of conscience: moral affect (which included guilt, shame, sympathy, and empathic anger) and moral cognition (which included internalization and prosocial moral reasoning). Parental discipline related to both dimensions of conscience, albeit in different ways. High levels of parental inductive discipline and low levels of parental power assertion were associated with high levels of moral affect, whereas high levels of persistent discipline were associated with increased moral cognition. High negative reactivity, however, was only associated with high levels of moral affect. In general, higher levels of moral affect were associated with prosocial behavior and moral conduct during bullying. Higher levels of moral cognition were associated with less participation in bullying, more altruistic behavior, and more frequent helping of the victims of bullying. The discussion focuses on the dimensions of moral conscience in adolescence.
