Perceptions About Sexual Offenses: Misconceptions, Punitiveness, and Public Sentiment

Decades of research on public opinion about crime reveal varying, yet relatively punitive attitudes that are often riddled with misconceptions. Sparked by the increased media and legislative attention devoted to sex offenders beginning in the 1990s, researchers began to more closely examine public opinion about sexual offenses. Findings suggest the public adheres to several misconceptions about sexual offenses and supports harsh sanctions for offenders. However, further research is warranted to more closely examine the relationships among these variables. Thus, the goal of the present study was to survey Pennsylvania residents to examine the degree to which misconceptions about sexual offenses inform punitiveness. The results supported the hypotheses in that a high level of support for misconceptions and punitiveness was identified, and adherence to misconceptions was the strongest predictor of punitiveness. These findings demonstrate a clear need for educational and awareness efforts to dispel public misconceptions about sexual offending and victimization

University Student Beliefs About Sexual Violence in Prison: Rape Myth Acceptance, Punitiveness, and Empathy

Although prison rape has been recognised for years, it began to receive increased attention in the USA following the passage of the Prison Rape Elimination Act (PREA). In addition to prevalence and victimisation estimates, several researchers have examined the attitudes of correctional personnel towards prison rape. However, few have surveyed the opinions of those not currently working in the criminal justice system. Drawing from the body of research on rape myths, our goal was to examine prison rape myth acceptance among a university student sample to describe these beliefs, as well as examine attitudinal correlates. The findings indicated that prison rape-supportive beliefs were evident among a minority of the sample and were predicted by general punitiveness and male and female rape myth acceptance. The acceptance of victim-blaming myths identified in this study warrants further investigation. It is possible that educational efforts would be successful in reducing these rape-supportive beliefs

The Complexity of Public Attitudes Toward Sex Crimes

Previous research suggests that public opinion about crime is nuanced as it has been found to vary greatly depending upon the type of questions asked and the amount of information provided. Few have similarly examined the complexity of public attitudes specifically about sex crimes. A survey was administered to a sample of U. S. residents utilizing the factorial survey method. The results suggested that specific details about the offense, offender, and victim had a significant effect on perceptions. The findings point to discrepancies between policy and public opinion, as well as to the importance of educating the public about the realities of sexual offending and victimization

“That is Not Behavior Consistent with a Rape Victim”: The Effects of Officer Displays of Doubt on Sexual Assault Case Processing and Victim Participation

Despite the prevalence and severity of sexual violence, case attrition has been identified as a significant issue. Of the cases that are reported to police, only a small portion result in arrest, prosecution, or conviction. Research has revealed that much of this attrition occurs early in the process and that a number of theoretically supported legal (e.g., physical evidence, victim participation) and extralegal (e.g., demographics, victim credibility) factors influence how and whether a case progresses through the criminal justice system. However, few researchers have directly examined the impact of officer doubt on case processing. Whereas legal and extralegal factors represent case characteristics, doubt represents officer cognition about these characteristics. These perceptions can affect how victims are treated, how police investigate the case, and ultimately, the case’s progression through the system. A random sample of sexual assault reports from one police department in a medium-sized jurisdiction in the western U.S. was drawn to examine the expression of officer doubt, as well as its impact on victim participation, arrest, and referral for prosecution while controlling for relevant legal and extralegal factors. The findings suggest that officer doubt is an important consideration in sexual assault case processing, independent of other legal and extralegal factors, and that it significantly impacts the likelihood of arrest and referral for prosecution. Consistent with previous research, police decision-making was also impacted by certain legal factors. Victim participation was not directly affected by officer doubt but it was predicted by extralegal factors. Implications for future sexual assault research and practitioner training are discussed

False Ring Formation in Eastern Hemlock Branches: Impacts of Hemlock Woolly Adelgid and Elongate Hemlock Scale

Herbivores can alter plant physiology through the induction of abnormal wood formation. Feeding by some insects induces the formation of false rings, a band of thick-walled latewood cells within the earlywood portion of the tree ring that reduces water transport. Hemlock woolly adelgid (Adelges tsugae Annand) and elongate hemlock scale (Fiorinia externa Ferris) are invasive insects that both feed on eastern hemlock [Tsuga canadensis (L.) CarriÈre]. Adelges tsugae has a greater effect on tree health than F. externa, but the mechanism underlying their differential effect is unknown. We explored the effects of these herbivores by assessing growth ring formation in branches of trees that had been experimentally infested for 4 yr with A. tsugae, F. externa, or neither insect. We measured false ring density, ring growth, and earlywood: latewood ratios in the two most recently deposited growth rings. Branches from A. tsugae-infested trees had 30% more false rings than branches from F. externa-infested trees and 50% more than branches from uninfested trees. In contrast, branches from F. externa-infested trees and control trees did not differ in false ring formation. Radial growth and earlywood: latewood ratios did not differ among treatments. Our results show that two invasive herbivores with piercing-sucking mouth parts have differing effects on false ring formation in eastern hemlock. These false rings may be the product of a systemic plant hypersensitive response to feeding by A. tsugae on hemlock stems. If false rings are responsible for or symptomatic of hemlock water stress, this may provide a potential explanation for the relatively large effect of A. tsugae infestations on tree health

Impaired contextual modulation of memories in PTSD: an fMRI and psychophysiological study of extinction retention and fear renewal

Post-traumatic stress disorder (PTSD) patients display pervasive fear memories, expressed indiscriminately. Proposed mechanisms include enhanced fear learning and impaired extinction or extinction recall. Documented extinction recall deficits and failure to use safety signals could result from general failure to use contextual information, a hippocampus-dependent process. This can be probed by adding a renewal phase to standard conditioning and extinction paradigms. Human subjects with PTSD and combat controls were conditioned (skin conductance response), extinguished, and tested for extinction retention and renewal in a scanner (fMRI). Fear conditioning (light paired with shock) occurred in one context, followed by extinction in another, to create danger and safety contexts. The next day, the extinguished conditioned stimulus (CS+E) was re-presented to assess extinction recall (safety context) and fear renewal (danger context). PTSD patients showed impaired extinction recall, with increased skin conductance and heightened amygdala activity to the extinguished CS+ in the safety context. However, they also showed impaired fear renewal; in the danger context, they had less skin conductance response to CS+E and lower activity in amygdala and ventral-medial prefrontal cortex compared with combat controls. Control subjects displayed appropriate contextual modulation of memory recall, with extinction (safety) memory prevailing in the safety context, and fear memory prevailing in the danger context. PTSD patients could not use safety context to sustain suppression of extinguished fear memory, but they also less effectively used danger context to enhance fear. They did not display globally enhanced fear expression, but rather showed a globally diminished capacity to use contextual information to modulate fear expression

Adverse Childhood Experiences and Current Cannabis Use among U.S. Young Adults

Cannabis use is a significant public health issue among U.S. young adults. The objective of this study was to assess the associations between adverse childhood experiences (ACEs) and current cannabis use among U.S. young adults. We conducted a secondary analysis of the 2021 Behavioral Risk Factor Surveillance System (BRFSS) data, which involved 498 U.S. young adults 18-24 years old who had data available for analysis on ACEs and current cannabis use. Unadjusted and adjusted logistic regression models were fitted to examine the associations between ACEs and current cannabis use. Adjusted models included participants’ sex, race/ethnicity, education level, and household income level. One-fourth (25.5%) of participants reported current cannabis use, and 21.3% reported one ACE, 25.2% reported 2-3 ACEs, and 38.4% reported ≥4 ACEs. Unadjusted (odds ratio [OR]=4.22, 95% confidence interval [CI]=1.91-9.33) and adjusted (adjusted OR=4.23, 95%CI=1.57-11.38) model results indicated that participants who experienced ≥1 ACE were at increased odds of reporting current cannabis use than participants with no ACEs. Unadjusted (OR=5.79, 95%CI=2.40-14.00) and adjusted (AOR=6.48, 95%CI=2.15-19.55) model results indicated that participants who experienced ≥4 ACEs were at increased odds of reporting current cannabis use than participants with no ACEs. Adjusted model results revealed that experiencing living with a household member who had a mental illness or sexual abuse increased the odds of reporting current cannabis use. Results demonstrated relations among ACEs and current cannabis use in young adulthood, especially among those who experienced ≥4 ACEs and experienced living with a household member who had a mental illness or sexual abuse

Are Exotic Herbivores Better Competitors? A Meta-Analysis

Competition plays an important role in structuring the community dynamics of phytophagous insects. As the number and impact of biological invasions increase, it has become increasingly important to determine whether competitive differences exist between native and exotic insects. We conducted a meta-analysis to test the hypothesis that native/exotic status affects the outcome of herbivore competition. Specifically, we used data from 160 published studies to assess plant-mediated competition in phytophagous insects. For each pair of competing herbivores, we determined the native range and coevolutionary history of each herbivore and host plant. Plant-mediated competition occurred frequently, but neither native nor exotic insects were consistently better competitors. Spatial separation reduced competition in native insects but showed little effect on exotics. Temporal separation negatively impacted native insects but did not affect competition in exotics. Insects that coevolved with their host plant were more affected by interspecific competition than herbivores that lacked a coevolutionary history. Insects that have not coevolved with their host plant may be at a competitive advantage if they overcome plant defenses. As native/exotic status does not consistently predict outcomes of competitive interactions, plant–insect coevolutionary history should be considered in studies of competition

Prominent astrocytic alpha-synuclein pathology with unique post-translational modification signatures unveiled across Lewy body disorders

Alpha-synuclein (aSyn) is a pre-synaptic monomeric protein that can form aggregates in neurons in Parkinson’s disease (PD), Parkinson’s disease with dementia (PDD) and dementia with Lewy bodies (DLB), and in oligodendrocytes in multiple system atrophy (MSA). Although aSyn in astrocytes has previously been described in PD, PDD and DLB, the biochemical properties and topographical distribution of astrocytic aSyn have not been studied in detail. Here, we present a systematic investigation of aSyn astrocytic pathology using an expanded antibody toolset covering the entire sequence and key post-translational modifications (PTMs) of aSyn in Lewy body disorders (LBDs) and in MSA. Astrocytic aSyn was detected in the limbic cortical regions of LBDs but were absent in main pathological regions of MSA. The astrocytic aSyn was revealed only with antibodies against the mid N-terminal and non-amyloid component (NAC) regions covering aSyn residues 34–99. The astroglial accumulations were negative to canonical aSyn aggregation markers, including p62, ubiquitin and aSyn pS129, but positive for phosphorylated and nitrated forms of aSyn at Tyrosine 39 (Y39), and not resistant to proteinase K. Our findings suggest that astrocytic aSyn accumulations represent a major part of aSyn pathology in LBDs and possess a distinct sequence and PTM signature that is characterized by both N- and C-terminal truncations and modifications at Y39. This is the first description that aSyn accumulations are made solely from N- and C-terminally cleaved aSyn species and the first report demonstrating that astrocytic aSyn is a mixture of Y39 phosphorylated and nitrated species. These observations underscore the importance of systematic characterization of aSyn accumulations in different cell types to capture the aSyn pathological diversity in the brain. Our findings combined with further studies on the role of astrocytic pathology in the progression of LBDs can pave the way towards identifying novel disease mechanisms and therapeutic targets
