Libertarian Acceptance Among the Students of the University of Southern Mississippi

How can a potential libertarian portion of USM students be differentiated from the conservative and liberal segments? The most obvious method is to classify students by their respective demographic factors. Demographic categories such as gender, race, age, religion, field of study, etc. could prove to be extremely useful when attempting to identify patterns in populations. The connections between these variables and political ideology are further examined in the literature review. The demographics of a potential libertarian faction have yet to be defined, specifically at the University of Southern Mississippi. Therefore, the goal of my research will be to first locate a potential libertarian population among the students at USM. If a significant libertarian sample is found, an analysis of the demographic patterns of this potential population will be conducted. Review of pertinent literature along with an analysis of a student sample will allow an answer to the research question, “To what extent does the current student population at the University of Southern Mississippi accept the political philosophy of libertarianism, regardless of party affiliation or self-identification as “liberal” or “conservative

Rarefaction effects on Galileo probe aerodynamics

Solutions of aerodynamic characteristics are presented for the Galileo Probe entering Jupiter's hydrogen-helium atmosphere at a nominal relative velocity of 47.4 km/s. Focus is on predicting the aerodynamic drag coefficient during the transitional flow regime using the direct simulation Monte Carlo (DSMC) method. Accuracy of the probe's drag coefficient directly impacts the inferred atmospheric properties that are being extracted from the deceleration measurements made by onboard accelerometers as part of the Atmospheric Structure Experiment. The range of rarefaction considered in the present study extends from the free molecular limit to continuum conditions. Comparisons made with previous calculations and experimental measurements show the present results for drag to merge well with Navier-Stokes and experimental results for the least rarefied conditions considered

Validation of a Measure to Assess Alcohol- and Marijuana-Related Risks and Consequences Among Incarcerated Adolescents

Few measures exist to assess risky behaviors and consequences as they relate to substance use in juvenile delinquents. This study sought to validate such a measure on a racially and ethnically diverse sample (N = 175). Results indicate that alcohol-related risky behaviors and consequences comprise a single scale as do marijuana-related risky behaviors and consequences. Furthermore, results suggest that the retention of common items for both scales produces reliable and valid scales and maintains parsimony. Internal consistencies were more than adequate (0.72 – 0.83) and test-retest stabilities, even across several months were acceptable (0.52 - 0.50). The scales evidenced a high degree of concurrent and predictive incremental validity in predicting conduct disorder, dependence symptoms, and consumption patterns. Researchers can use these scales to measure a generalized construct tapping risks and consequences as related to alcohol and marijuana use. Ease of use may make these scales appealing to clinicians who can provide feedback to clients regarding risky behaviors involving alcohol and marijuana

Cannabis Withdrawal Among Detained Adolscents: Exploring the Impact of Nicotine and Race

Rates of marijuana use among detained youths are exceptionally high. Research suggests a cannabis withdrawal syndrome is valid and clinically significant; however, these studies have mostly been conducted in highly controlled laboratory settings with treatment-seeking, White adults. The present study analyzed archival data to explore the magnitude of cannabis withdrawal symptoms within a diverse sample of detained adolescents while controlling for tobacco use and investigating the impact of race on symptom reports. Adolescents recruited from a juvenile correctional facility (N=93) completed a background questionnaire and the Marijuana Withdrawal Checklist. Analyses revealed a significant main effect for level of tobacco use on severity of irritability, and for level of marijuana use on severity of craving to smoke marijuana and strange/wild dreams. Furthermore, a significant main effect for race was found with Black adolescents reporting lower withdrawal discomfort scores and experiencing less severe depressed mood, difficulty sleeping, nervousness/anxiety, and strange/wild dreams. Although exploratory, these findings may have significant clinical implications for providers in juvenile detention facilities, allowing the execution of proper medical and/or behavioral interventions to assist adolescents presenting with problematic cannabis and/or tobacco withdrawal

individual participant data meta-analysis of randomised trials study protocol

Introduction Parenteral anticoagulants may improve outcomes in patients with cancer by reducing risk of venous thromboembolic disease and through a direct antitumour effect. Study-level systematic reviews indicate a reduction in venous thromboembolism and provide moderate confidence that a small survival benefit exists. It remains unclear if any patient subgroups experience potential benefits. Methods and analysis First, we will perform a comprehensive systematic search of MEDLINE, EMBASE and The Cochrane Library, hand search scientific conference abstracts and check clinical trials registries for randomised control trials of participants with solid cancers who are administered parenteral anticoagulants. We anticipate identifying at least 15 trials, exceeding 9000 participants. Second, we will perform an individual participant data meta-analysis to explore the magnitude of survival benefit and address whether subgroups of patients are more likely to benefit from parenteral anticoagulants. All analyses will follow the intention-to- treat principle. For our primary outcome, mortality, we will use multivariable hierarchical models with patient-level variables as fixed effects and a categorical trial variable as a random effect. We will adjust analysis for important prognostic characteristics. To investigate whether intervention effects vary by predefined subgroups of patients, we will test interaction terms in the statistical model. Furthermore, we will develop a risk-prediction model for venous thromboembolism, with a focus on control patients of randomised trials. Ethics and dissemination Aside from maintaining participant anonymity, there are no major ethical concerns. This will be the first individual participant data meta-analysis addressing heparin use among patients with cancer and will directly influence recommendations in clinical practice guidelines. Major cancer guideline development organisations will use eventual results to inform their guideline recommendations. Several knowledge users will disseminate results through presentations at clinical rounds as well as national and international conferences. We will prepare an evidence brief and facilitate dialogue to engage policymakers and stakeholders in acting on findings. Trial registration number PROSPERO CRD4201300352
