Gender performance and political identity at the January 6 Capitol insurrection

The January 6 Capitol insurrection was heavily documented with recorded videos and photos, across legacy and social media. Despite engaging in criminal acts, many participants recorded themselves participating in the attack and posted their videos to Parler, a right-wing alternative to Facebook and Twitter that gained traction among the far-right, QAnon conspiracy theorists, and white supremacy groups. These social media videos detail an interesting rhetorical dynamic at play, one that is not so recognizable in legacy media: performances of sex/gender. Analyzing videos uploaded to a conservative social media landscape provides a lens into performances of gender as it intersects with political identity, revealing new ways that communication studies scholars can understand how conservative arguments are constructed within gender performance. By utilizing R.W. Connell’s concepts of hegemonic masculinity and emphasized femininity, I rhetorically analyze over 2,500 videos uploaded by the January 6 insurrectionists to Parler. I argue that both masculine and feminine insurrectionists perform alternative politically conservative gendered performances which grant them new rhetorical affordances. This thesis identifies four performances: two masculine, which I term delinquent masculinity and militarized muscular Christianity, and two feminine, which I term den mother femininity and matriarchal warriors. All these gender performances exist in a dialectic with each other, and ultimately showcase the way that the insurrectionists envision, construct, and perform their intertwining political and gender roles

Early trauma and associations with altruistic attitudes and behaviours among young adults

Childhood and adolescent traumas are exceptionally prevalent worldwide. Despite their high prevalence and substantial impact, little research has investigated the rates and specific types of early trauma by gender. It is also unknown whether the types of early trauma are differentially associated with heightened or hindered prosocial attitudes and behaviours.info:eu-repo/semantics/publishedVersio

Identification and assessment of water quality risks associated with sludge supernatant recycling in the presence of cyanobacteria.

This study focussed on the fate of cyanobacteria cells and associated metabolites during the sludge management processes that follow the conventional drinking water treatment train. The topic is of importance, as the release of metabolites during sludge treatment may pose a risk to water quality if supernatant is recycled to the head of the plant. The study of the kinetics of cell damage and metabolite release into the supernatant is complicated by simultaneous and rapid natural removal processes. In this study, the release of organic material from cyanobacterial sludge was monitored simultaneously with secondary metabolites (Microcystins (MCs), cylindrosperopsin (CYN), and geosmin (GSM)) as an additional parameter to aid in understanding the range of processes occurring in sludge. Only GSM produced by Dolichospermum circinale was found to represent a low risk, as the compound is readily degraded. In contrast, the metabolites CYN and MC were shown to increase in concentration during simulated sludge treatment, suggesting that this could occur within full scale sludge treatment facilities with a range of cyanobacteria species, metabolites and water quality. A generic risk matrix was developed, incorporating the type of cyanobacteria, metabolite production, and the treatment

Adult life expectancy trends in the era of antiretroviral treatment in rural Uganda (1991-2012).

OBJECTIVE: To estimate the impact of antiretroviral therapy (ART) on population-wide adult life expectancy. STUDY DESIGN: A population-based open cohort study with repeated HIV status measurements and registration of vital events in Southwestern Uganda (1991-2012). METHODS: Nonparametric survival analysis techniques are used for estimating trends in the adult life expectancy of the general population (aged 15 and above), the adult life expectancy by HIV status, and the adult life expectancy deficit. The life expectancy deficit is estimated as the difference between overall life expectancy and life expectancy of the HIV-negative population. All estimates are disaggregated by sex. RESULTS: Between 1991-1993 and 2009-2012, population-wide adult life expectancy increased from 39.3 [95% confidence interval (CI): 35.9-42.8] to 56.1 years (95% CI: 54.0-58.5) in women, and from 38.6 (95% CI: 35.4-42.1) to 51.4 years (95% CI: 49.2-53.7) in men. Most of the adult life expectancy gains coincide with the introduction of ART in 2004; as evidenced by an increase in the adult life expectancy of people living with HIV between 2000-2002 and 2009-2012 of 22.9 and 20.0 years for women and men, respectively. Over the whole period of observation, the adult life expectancy deficit associated with HIV decreased from 16.1 (95% CI: 12.7-19.8) to 6.0 years (95% CI: 4.1-7.8) among women, and from 16.0 (95% CI: 12.1-19.9) to 2.8 years (95% CI: 1.2-4.6) among men. CONCLUSION: Population-wide life expectancy increased substantially, largely driven by reductions in HIV-related mortality. Women have gained more adult life years than men since the introduction of ART, but the burden of HIV in terms of the life years lost is still larger for women than it is for men

Redox‐active hybrid polyoxometalate‐stabilised gold nanoparticles

We report the design and preparation of multifunctional hybrid nanomaterials through the stabilization of gold nanoparticles with thiol‐functionalised hybrid organic–inorganic polyoxometalates (POMs). The covalent attachment of the hybrid POM forms new nanocomposites that are stable at temperatures and pH values which destroy analogous electrostatically functionalised nanocomposites. Photoelectrochemical analysis revealed the unique photochemical and redox properties of these systems

Universal cannabis outcomes from the Climate and Preventure (CAP) study : a cluster randomised controlled trial

Background: The Climate and Preventure (CAP) study was the first trial to assess and demonstrate the effectiveness of a combined universal and selective approach for preventing alcohol use and related harms among adolescents. The current paper reports universal effects from the CAP study on cannabis-related outcomes over three years. Methods: A cluster randomized controlled trial was conducted with 2190 students from twenty-six Australian high schools (mean age: 13.3 yrs., SD 0.48). Participants were randomised to one of four conditions; universal prevention for all students (Climate); selective prevention for high-risk students (Preventure); combined universal and selective prevention (Climate and Preventure; CAP); or health education as usual (Control). Participants were assessed at baseline, post intervention (6–9 months post baseline), and at 12-, 24- and 36-months, on measures of cannabis use, knowledge and related harms. This paper compares cannabis-related knowledge, harms and cannabis use in the Control, Climate and CAP groups as specified in the protocol, using multilevel mixed linear models to assess outcomes. Results: Compared to Control, the Climate and CAP groups showed significantly greater increases in cannabis-related knowledge initially (p < 0.001), and had higher knowledge at the 6, 12 and 24-month follow-ups. There was no significant difference between the Climate and CAP groups. While no differences were detected between Control and the CAP and Climate groups on cannabis use or cannabis-related harms, the prevalence of these outcomes was lower than anticipated, possibly limiting power to detect intervention effects. Additional Bayesian analyses exploring confidence in accepting the null hypothesis showed there was insufficient evidence to conclude that the interventions had no effect, or to conclude that they had a meaningfully large effect. Conclusions: Both the universal Climate and the combined CAP programs were effective in increasing cannabisrelated knowledge for up to 2 years. The evidence was inconclusive regarding whether the interventions reduced cannabis use and cannabis-related harms. A longer-term follow-up will ascertain whether the interventions become effective in reducing these outcomes as adolescents transition into early adulthood

The validity of the Substance Use Risk Profile Scale (SURPS) among Australian adolescents

Aims: This study investigated the validity of a brief personality screening measure for substance use in adolescents, the Substance Use Risk Profile Scale (SURPS), among Australian adolescents. Design and participants: A total of 527 adolescents (mean age: 13.38 years, SD=0.43) from seven Australian schools were assessed at two time points 24 months apart. The concurrent and predictive validity of the SURPS was determined using a series of linear and logistic regressions, and was compared to the results in a United Kingdom (UK) sample. SURPS subscale scores for the Australian population were also reported and compared to those in the UK. Findings: Overall, the SURPS subscale scores for Australian adolescents were similar to those for adolescents from the UK. Tests of concurrent and predictive validity in the Australian sample demonstrated that the all four personality profiles - Hopelessness (H), Anxiety Sensitivity (AS), Impulsivity (IMP), and Sensation Seeking (SS) - were related to measures of substance use and other behavioural and emotional characteristics. In addition, all the predicted specific prospective relationships between the personality profiles and particular substance use and other behavioural problems were confirmed except that H was not associated with illicit drug use. Overall, the results were similar between the Australian and UK samples. Conclusions: The SURPS is a valid and useful measure for identifying Australian adolescents at high-risk for substance use and other emotional and behavioural problems. Implications for prevention are discussed
