    The societal and personal costs of aggressive and violent behavior have reached alarming levels within the United States. In the literature, several personality and personal factors have been uncovered as valuable predictors of aggressive and violent behavior. However, it may be the case another variable has been unduly discounted in its link to aggression. Masculine Honor Ideology (MHI) refers to a set of beliefs that dictate men must respond aggressively to threat or insult in order to maintain their ideal masculine reputation. The intent of the current study is to demonstrate the robust relationship that exists between MHI and lifetime aggressive behaviors in a nationwide study of adult men and to examine this relationship within the context of already established predictors of aggressive behavior. The predictors MHI will be compared to include maladaptive masculinity indicators (i.e., Toxic Masculinity, Puritanical Masculinity, and Ambivalence in Sexual Situations), and personality traits (i.e., Antagonism, Disinhibition, Negative Affect, Detachment, and Psychoticism). Participants included 732 adult men (M age = 36.27) residing in the United States. It was hypothesized that MHI would account for unshared variance in lifetime aggression in regression models that control for the impact of personality and masculinity dimensions. Results indicated MHI outperformed maladaptive masculinity indicators in the prediction of lifetime aggression criterion variables. Antagonism appeared to be an overall stronger predictor of aggressive behavior; however, for one of the criterion variables, Antagonism and MHI contributed equally to the model. The study also hypothesized the odds of endorsing past aggressive behavior would be increased by stronger adherence to MHI. This hypothesis was supported and individuals who reported increased MHI adherence also displayed increased odds of endorsing a range of past aggressive behaviors and other indicators of lifetime maladjustment. Overall results suggested MHI offers a unique explanation of aggressive behavior. Additional research is required to gain a more nuanced understanding of the relationship between these variables. These findings also have implications for aggression intervention and prevention efforts

    Executive Functioning And Drinking: The Impact Taxing Working Memory Has On Alcohol Consumption

    The prevalence rates of binge drinking and heavy drinking among college-aged students have reached alarming levels. The negative consequences for these behaviors range from relatively minor annoyances (e.g., hangovers) to life-changing incidents (e.g., DUI) to accidental death. Deficits in executive cognitive function (ECF), especially deficits in working memory capabilities, have been linked repeatedly to problematic alcohol use. Given that it appears problematic drinkers with ECF deficits are more susceptible to the effects of alcohol and experience a greater loss of behavior control when experiencing cognitively taxing situations than problematic drinkers with greater ECF, further study of the impact of taxing working memory is warranted. The current study is an attempt to demonstrate the effect that depleting working memory resources has on alcohol consumption. It was hypothesized that participants who underwent working memory depletion would drink significantly more alcohol than participants who did not, and that individuals who experienced working memory depletion and who displayed poorer baseline ECF would drink the most. Twenty-four binge and/or heavy drinkers (66.7% men; M age = 22.95) participated in the study. During their visit, participants were randomized to complete either a task designed to deplete working memory resources or a control task that did not deplete working memory resources. After completing this task, participants completed an alcohol taste-rating task. The study hypotheses were supported, as the experimental condition drank significantly more alcohol and, within the experimental condition, individuals with poorer functioning consumed the greatest amount of alcohol. These findings shed light on the cognitive processes that contribute to problematic alcohol use and support the investigation of cognitive interventions for a subset of problematic drinkers

    Lawson criterion for ignition exceeded in an inertial fusion experiment

    Get PDF
    For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion

    Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

    Get PDF
    Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

    The highly infectious disease COVID-19 caused by the Betacoronavirus SARS-CoV-2 poses a severe threat to humanity and demands the redirection of scientific efforts and criteria to organized research projects. The international COVID19-NMR consortium seeks to provide such new approaches by gathering scientific expertise worldwide. In particular, making available viral proteins and RNAs will pave the way to understanding the SARS-CoV-2 molecular components in detail. The research in COVID19-NMR and the resources provided through the consortium are fully disclosed to accelerate access and exploitation. NMR investigations of the viral molecular components are designated to provide the essential basis for further work, including macromolecular interaction studies and high-throughput drug screening. Here, we present the extensive catalog of a holistic SARS-CoV-2 protein preparation approach based on the consortium’s collective efforts. We provide protocols for the large-scale production of more than 80% of all SARS-CoV-2 proteins or essential parts of them. Several of the proteins were produced in more than one laboratory, demonstrating the high interoperability between NMR groups worldwide. For the majority of proteins, we can produce isotope-labeled samples of HSQC-grade. Together with several NMR chemical shift assignments made publicly available on covid19-nmr.com, we here provide highly valuable resources for the production of SARS-CoV-2 proteins in isotope-labeled form
