Drinking Behavior Among College Students: Interventions to Increase Mindfulness and Social Capital

The impacts of drinking behaviors are far-reaching, with college student drinking contributing to over 1,500 deaths and an estimated 696,000 assaults on college campuses each year (National Institute on Alcohol Abuse and Alcoholism [NIAAA], 2019). There are a variety of explanations to explain why college students engage in risky drinking behaviors. However, there is evidence to suggest that drinking and other substance use may be a result of complex psychological origins, including adverse childhood experiences (ACEs). This paper reviews the literature available on ACEs among college students, how these experiences impact alcohol use among this population, and potential areas for intervention, including those with a focus on mindfulness and social capital

Addressing Food Insecurity: A Qualitative Study of Undergraduate Students\u27 Perceptions of Food Access Resources.

Food insecurity has emerged as a leading health care problem in the United States, impacting college students’ health, well-being, and academic performance. The aims of this study were: (1) to assess the prevalence of food insecurity, (2) to identify college students’ perceptions about food access resources, and (3) to explore students’ expressed needs from the university in improving food security status. A mixed-methods approach was used to assess the quantitative and qualitative aspects of the study aims. An online survey to gather demographic information and assess food security status using the 6-item version of the US Household Food Security Scale Module (HFSSM) was administered. Next, qualitative focus groups with subsets of participants was conducted to gain further insight into the perceptions, coping mechanisms, and resource utilization issues related to food insecurity. This study found 34.1% of undergraduate college students to be food insecure and demonstrates that students with a meal plan are less likely to be food insecure (p = 0.012; OR = 0.68; 95% CI = 0.489, 0.918). Qualitative data identified key influencers of food insecurity: (1) personal beliefs, (2) life skills, and (3) the university. The results of this study contribute to the literature focused on food insecurity prevalence in college students and presents insight from the college student perspective. Findings may support the development of relevant interventions that are congruent with students’ needs, enhancing resource utilization to increase food security status among college students

Scaling of Majorana Zero-Bias Conductance Peaks

We report an experimental study of the scaling of zero-bias conductance peaks compatible with Majorana zero modes as a function of magnetic field, tunnel coupling, and temperature in one-dimensional structures fabricated from an epitaxial semiconductor-superconductor heterostructure. Results are consistent with theory, including a peak conductance that is proportional to tunnel coupling, saturates at $2e^2/h$, decreases as expected with field-dependent gap, and collapses onto a simple scaling function in the dimensionless ratio of temperature and tunnel coupling.Comment: Accepted in Physical Review Letter

Making COVID-19-Related Decisions: A Qualitative Study of University Students

Background: SARS-Cov-2 (Coronavirus Disease or COVID-19) has impacted society greatly since its arrival to the United States. More specifically, college students have had to modify their behaviors on campus to minimize the spread of the virus.Purpose: The purpose of this study was to identify benefits and barriers to testing, reporting, and quarantining of undergraduate college students attending a large southeastern university.Methods: Undergraduate students were asked to complete an open-ended Qualtrics survey to share their perceived benefits and barriers to engage in behaviors to detect and prevent the spread of COVID-19. Data was analyzed via Grounded Theory techniques to determine codes and subsequent themes related to the probes.Results: Themes emerged in the categories of (a) Influencing Factors, and (b) Outcomes of the Health Behavior with 12 in the former and six in the latter. Emphasis on disclosure of COVID-19 status could be beneficial in preventing the spread of the virus on large college and university campuses.Conclusion: The data collected in this study can be used to inform COVID-19-related policies and health communication campaigns at similar colleges and universities

Evidence of topological superconductivity in planar Josephson junctions

Majorana zero modes are quasiparticle states localized at the boundaries of topological superconductors that are expected to be ideal building blocks for fault-tolerant quantum computing. Several observations of zero-bias conductance peaks measured in tunneling spectroscopy above a critical magnetic field have been reported as experimental indications of Majorana zero modes in superconductor/semiconductor nanowires. On the other hand, two dimensional systems offer the alternative approach to confine Ma jorana channels within planar Josephson junctions, in which the phase difference {\phi} between the superconducting leads represents an additional tuning knob predicted to drive the system into the topological phase at lower magnetic fields. Here, we report the observation of phase-dependent zero-bias conductance peaks measured by tunneling spectroscopy at the end of Josephson junctions realized on a InAs/Al heterostructure. Biasing the junction to {\phi} ~ {\pi} significantly reduces the critical field at which the zero-bias peak appears, with respect to {\phi} = 0. The phase and magnetic field dependence of the zero-energy states is consistent with a model of Majorana zero modes in finite-size Josephson junctions. Besides providing experimental evidence of phase-tuned topological superconductivity, our devices are compatible with superconducting quantum electrodynamics architectures and scalable to complex geometries needed for topological quantum computing.Comment: main text and extended dat

Impact of a Summer Nutrition and Physical Activity Intervention to Attenuate Obesity in Urban African-American Youth

Improved eating behaviors and daily participation in physical activity such as swimming might abate the likelihood of African American youth becoming obese. Yet many African American youth neither consume the recommended daily servings of nutritious foods nor know how to swim. The purpose of this study was to investigate the impact of a culturally tailored multicomponent summer intervention to reduce obesity and unintentional drownings among underserved African American youth. Children (n = 145) participated in a three-hour, community-based intervention for four weeks. Measures of children’s attitudes perceived behavioral control, and subjective norms toward swimming, nutrition, and physical fitness were taken at baseline and 4 weeks later (n = 47). The only post-intervention significant finding indicated an improvement in children’s skillfulness in floating on their back without help. The limited changes in this multi-component program suggested that such interventions need to be longer in duration, intensity, and be required to reduce attrition

Performing thinking in action: the meletē of live coding

Within this article, live coding is conceived as a meletē, an Ancient Greek term used to describe a meditative thought experiment or exercise in thought, especially understood as a preparatory practice supporting other forms of critical — even ethical — action. Underpinned by the principle of performing its thinking through 'showing the screen', live coding involves 'making visible' the process of its own unfolding through the public sharing of live decision-making within improvisatory performance practice. Live coding can also be conceived as the performing of 'thinking-in-action', a live and embodied navigation of various critical thresholds, affordances and restraints, where its thinking-knowing cannot be easily transmitted nor is it strictly a latent knowledge or 'know how' activated through action. Live coding involves the live negotiation between receptivity and spontaneity, between the embodied and intuitive, between an immersive flow experience and split-attention, between human and machine, the known and not yet known. Moreover, in performing 'thinking-in-action', live coding emerges as an experimental site for reflecting on different perceptions and possibilities of temporal experience within live performance: for attending to the threshold between the live and mediated, between present and future-present, proposing even a quality of atemporality or aliveness

Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb−1 of s√=7TeV proton-proton collisions

Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb−1 of pp collision data at s√=7TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from ≥6 to ≥9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m 0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson
