Duke D. Biber and Amanda Redinger
- Abstract
Active shooter drills are widely used in schools throughout the United States, with more than 92% of public schools having an active shooter plan. These drills can increase student stress and anxiety and can have a variety of negative effects, such as somatic complaints, anxiety, poor self-regulation of emotions and behaviors, risk for depression, and prevalence of obesity and eating disorders. This article describes the efficacy of physical activity breaks, mindful breathing techniques, and emotional regulation strategies to reduce stress reactivity and enhance recovery in elementary-age students following active shooter safety drills. A list of example activities is provided for each of the three stress management categories. Each of the activities can be adapted to various developmental levels (i.e., K-12), settings (i.e., classroom, hallway, outdoors), and time availability (i.e., one minute to 10 minutes). The strategies may also be utilized following other emergency drills or during other times of high student and classroom stress.

Biber, Duke D., Czech, Daniel R., Donald, Ellen K., Hassett, Anna, and Tucker, Allison
- Abstract
In this study, we examine the relationship between sleep duration and reported levels of optimism in Generation Z (i.e., born after 1996) students aged 17 to 24. This study hypothesizes that optimism and duration of sleep will have a statistically significant positive relationship. Participants in this study are Generation Z college students located in the Southeastern United States. The sample consisted of 1562 students enrolled in a required physical activity class. A Pearson's correlation determined that there was a statistically significant positive relationship between sleep and optimism. Research implications and future research trends on sleep and optimism are discussed. [Note: The publication year (2021) shown on the PDF is incorrect.

Physics - Instrumentation and Detectors ,Nuclear Experiment - Abstract
Recent theoretical and experimental results have brought renewed interest and focus on the topic of fission fragment angular momentum. Measurements of neutrons and $\gamma$ rays in coincidence with fission fragments remain the most valuable tool in the exploration of fission physics. To achieve these scientific goals, we have developed a system that combines a state-of-the-art fission fragment detector and $n$-$\gamma$ radiation detectors. A new twin Frisch-gridded ionization chamber has been designed and constructed for use with a spontaneous fission source and an array of forty \textit{trans}-stilbene organic scintillators (FS-3) at Argonne National Laboratory. The new ionization chamber design we present in this work aims at minimizing particle attenuation in the chamber walls, and provides a compact apparatus that can be fit inside existing experimental systems. The ionization chamber is capable of measuring fission fragment masses and kinetic energies, whereas the FS-3 provides neutron and gamma-ray multiplicities and spectra. The details of both detector assembly are presented along with the first experimental results of this setup. Planned event-by-event analysis and future experiments are briefly discussed., Comment: 7 pages, 10 figures

Biber, Duke D. and Brandenburg, Gina
- Abstract
The purpose of this study was to examine the relationship between curiosity, gratitude, and life satisfaction in undergraduate college students. It was hypothesized that there would be a significant relationship between gratitude, curiosity, and satisfaction with life. College students from a southeastern college were recruited via email, in-class announcements, and throughout campus via QR codes to participate in the study. A total of 300 undergraduate students consented to participate in the research study and 231 completed the surveys. Participants completed surveys assessing curiosity, gratitude, and satisfaction with life. Data was analyzed using descriptive statistics, Pearson's r correlations, and separate one-way ANOVAs to determine group differences in gratitude, curiosity, and satisfaction with life. Hedge's g effect sizes were calculated as well. Gratitude was positively related to curiosity (r = 0.20), and satisfaction with life (r = 0.36). Furthermore, women exhibited greater gratitude as well as satisfaction with life when compared to men, [F(2,230) = 14.40, p < 0.001]. These results are consistent with the hypotheses and will be discussed in regard to previous research and future application.

Nuclear Experiment - Abstract
Neutron-induced fission of $^{237}$Np has been measured over a wide range of incident neutron energies using a twin Frisch-gridded ionization chamber (TFGIC) and a thin-backed $^{237}$Np target. These measurements were performed at the Los Alamos Neutron Science Center - Weapons Neutron Research (LANSCE - WNR) facility, which provides a collimated beam of neutrons with energies ranging from 100s of keV to 100s of MeV. The data were analyzed using the double-energy ($2E$) method, with mass-dependent corrections for prompt-fission neutrons and pulse height defect. Pre- and post-neutron evaporation average total kinetic energy ($\langle TKE\rangle$) values are reported for 54 incident neutron energies in the energy range $0.20 \le E_n \le 100.0$ MeV and compared to existing data and evaluations. Pre- and post-neutron evaporation mass yields were extracted with a full width at half maximum (FWHM) resolution of 4u and compared to existing data and evaluations. The present $\langle TKE\rangle$ and mass yield data agree with previous results and also with statistical models of $^{237}$Np$(n,f)$ at incident neutron energies between $E_n = 0.2 - 20.0$ MeV. A flattening of the $\langle TKE\rangle$ data is observed (relative to the prediction of the GEF model) above $E_n = 20.0$ MeV. However, the interpretation of this discrepancy is unclear as the analysis method's neglect of incomplete momentum transfer at high energies, as well as pre-equilibrium pre-fission phenomena likely have a significant impact on the measurement at such high incident neutron energies., Comment: 28 pages, 13 captioned figures, 4 tables, submitted to Journal of Physics G

Nuclear Experiment - Abstract
The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) collaboration has performed measurements with a fission time projection chamber (fissionTPC) to study the fission process by reconstructing full three-dimensional tracks of fission fragments and other ionizing radiation. The amount of linear momentum imparted to the fissioning nucleus by the incident neutron can be inferred by measuring the opening angle between the fission fragments. Using this measured linear momentum, fission fragment angular distributions can be converted to the center-of-mass frame for anisotropy measurements. Angular anisotropy is an important experimental observable for understanding the quantum mechanical state of the fissioning nucleus and vital to determining detection efficiency for cross section measurements. Neutron linear momentum transfer to fissioning $^{235}$U, $^{238}$U, and $^{239}$Pu and fission fragment angular anisotropy of $^{235}$U and $^{238}$U as a function of neutron energies in the range 130 keV--250 MeV are presented.

- Abstract
Objective: To examine the relationship between college student anxiety, optimism, gratitude, and perception of the Physical Activity and Lifestyle program (PAL) instructional response/effectiveness following COVID-19. Participants: Data were collected from a southeastern, midsize university (n = 1640) during April 2020. Methods: Participants responded to a Web-based survey that included mental health factors (optimism, gratitude, anxiety) and perceptions of COVID-19 academic response. Results: The results of this study revealed a significant, negative relationship between anxiety and optimism (r = 0.36), gratitude (r = -0.12), and perceived instruction following COVID-19 (r = -0.11). There were statistically significant differences in perceived PAL instructional response/effectiveness following COVID-19 between anxiety classification, with severely anxious students expressing lower instructional response to COVID-19 when compared to moderately or mildly anxious students, [F(2,1516) = 10.60, p < 0.001]. Conclusions: The results inform educators on the importance of effective education and coping strategies following online transition during a pandemic.

Nuclear Experiment ,Physics - Instrumentation and Detectors - Abstract
The normalized $^{238}$U(n,f)/$^{235}$U(n,f) cross section ratio has been measured using the NIFFTE fission Time Projection Chamber from the reaction threshold to $30$~MeV. The fissionTPC is a two-volume MICROMEGAS time projection chamber that allows for full three-dimensional reconstruction of fission-fragment ionization profiles from neutron-induced fission. The measurement was performed at the Los Alamos Neutron Science Center, where the neutron energy is determined from neutron time-of-flight. The $^{238}$U(n,f)/$^{235}$U(n,f) ratio reported here is the first cross section measurement made with the fissionTPC, and will provide new experimental data for evaluation of the $^{238}$U(n,f) cross section, an important standard used in neutron-flux measurements. Use of a development target in this work prevented the determination of an absolute normalization, to be addressed in future measurements. Instead, the measured cross section ratio has been normalized to ENDF/B-VIII.$\beta$5 at 14.5 MeV.

The purpose of this study was to analyze the Sources of Strength program implemented at a high school in the southeastern United States using the RE-AIM framework. Students (n = 1,250) were recruited from one high school in the southeastern United States that was implementing Sources of Strength. College undergraduate students mentored high school peer leaders to implement Sources of Strength to promote opioid and suicide protective factors for the high school. This was a cross-sectional design in which a post-implementation survey assessed program effectiveness, satisfaction, and feedback for maintenance. Analysis used the RE-AIM framework of reach, effectiveness, adoption, implementation, and maintenance. Reach: 100 % of students participated in at least one campaign. Effectiveness: Mean protective factor scores were 3.83 for happiness; 3.93 for knowledge of coping skills, and 3.38 for practice of coping skills. Adoption: One high school and 100 % of classrooms participated in at least one campaign. Implementation: 18 high school peer leader meetings were facilitated by the undergraduate mentors. Maintenance: High school students qualitatively provided input on future campaign needs, and the program was continued following this RE-AIM analysis. The Sources of Strength program promoted suicide and opioid protective factors in high school students during COVID-19. Future research should compare the efficacy of Sources of Strength at baseline and follow-up with multiple high school sites.

Biber, Duke D. and Heidorn, Jennifer
- Abstract
Podcasting targets student engagement through technology-based blended learning and application of the four perspectives previously discussed. Podcast-based walking programs, based off of the Walking Classroom, promote exercise and learning without reducing educational time. The purpose of this commentary is to explain a teaching method that promotes blended learning through physical activity and podcast-based learning. Students expressed enjoyment and desire to continue this learning modality across other classes, believed they retained information better while walking, and that it helped them engage in physical activity after commuting to campus or sitting at work. Lastly, students expressed enjoyment with this style of learning because it helped energize and motivate them prior to class in the morning. The authors discussed this tailored teaching method for a university setting as well as future research implications.

Nuclear Experiment - Abstract
Fission fragment angular distributions can provide an important constraint on fission theory, improving predictive fission codes, and are a prerequisite for a precise ratio cross section measurement. Available anisotropy data is sparse, especially at neutron energies above 5 MeV. For the first time, a three-dimensional tracking detector is employed to study fragment emission angles and provide a direct measurement of angular anisotropy. The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) collaboration has deployed the fission time projection chamber (fissionTPC) to measure nuclear data with unprecedented precision. The fission fragment anisotropy of $^{235}$U has been measured over a wide range of incident neutron energies from 180 keV to 200 MeV; a careful study of the systematic uncertainties complement the data., Comment: 10 pages, 12 figures, accepted to Physical Review C

The purpose of this study was to screen for mental and behavioral health risk of Division II collegiate student athletes using a novel online screening tool (i.e., Heads Up Checkup) via the Sharpen mobile platform and learn the practicality of using such a tool. Collegiate student athletes (n = 367) were recruited to complete the Heads Up Checkup mental and behavioral health screening through the Sharpen mobile application. A total of 338 out of 367 possible collegiate student athletes completed the screening for a participation rate of 92.09%. Participants self-reported mental and behavioral health symptoms, including risk and criteria for 26 ICD-10 disorders. Across the sample, 17.1% of participants (n = 63) met at least 50% of the criteria for at least one diagnosis, 18.8% of participants (n = 69) met 70–99% of diagnostic criteria for at least one diagnosis, and 15.5% of participants (n = 57) met 100% of diagnostic criteria for at least one ICD-10 diagnosis. Although the Heads Up Checkup cannot diagnose disorders, it can be a valuable screening tool to assist coaches, trainers, clinicians, and athletic staff to collaboratively care for collegiate student athletes.

Context: Physical activity has been shown to have physiological and psychological benefits in adults worldwide. Those in the healthcare industry, including long-term care employees, face unique occupational stressors that could be barriers to initiating and maintaining a physically active lifestyle. Objectives: 1) to describe the physical activity level of a group of long-term care employees; and 2) examined demographic and self-efficacy influences on physical activity level. Methods: The cross-sectional study included an online questionnaire with demographics, the Godin Leisure-Time Exercise Questionnaire (GLTEQ), and the Self-Efficacy for Exercise Scale, in a convenience sample of 218 participants. Findings: Results found 71.5% of the sample were classified as active, the percentage of participants who indicated they were highly active in their youth compared to adulthood decreased from 40.3% to 16.0%, and 37.3% of the sample decreased their physical activity level during COVID-19. Additionally, the GLTEQ score was significantly higher for those with high exercise self-efficacy (M = 65.97, SD = 30.78) compared to those with moderate exercise self-efficacy (M = 37.14, SD = 27.07, p = .000) and low exercise self-efficacy (M = 16.00, SD = 15.11, p = .000). Implications: Although the majority of the long-term care employees were considered active even during the COVID-19 pandemic, strategies to promote physical activity in the occupation setting are needed. Additional research is warranted to better understand if the nature of healthcare and occupational physical activity may have impacted this value.

The fission Time Projection Chamber (fissionTPC) is a compact (15 cm diameter) two-chamber MICROMEGAS TPC designed to make precision cross section measurements of neutron-induced fission. The actinide targets are placed on the central cathode and irradiated with a neutron beam that passes axially through the TPC inducing fission in the target. The 4$\pi$ acceptance for fission fragments and complete charged particle track reconstruction are powerful features of the fissionTPC which will be used to measure fission cross sections and examine the associated systematic errors. This paper provides a detailed description of the design requirements, the design solutions, and the initial performance of the fissionTPC.

Nuclear Theory - Abstract
Eighty years after its experimental discovery, a microscopic description of induced nuclear fission based solely on the interactions between neutrons and protons and quantum many-body methods still poses formidable challenges. The goal of this paper is to contribute to the development of a predictive microscopic framework for the accurate calculation of static properties of fission fragments for hot fission and thermal or slow neutrons. To this end, we focus on the 239Pu(n,f) reaction and employ nuclear density functional theory with Skyrme energy densities. Potential energy surfaces are computed at the Hartree-Fock-Bogoliubov approximation with up to five collective variables. We find that the triaxial degree of freedom plays an important role, both near the fission barrier and at scission. The impact of the parameterization of the Skyrme energy density on deformation properties from the ground-state up to scission is also quantified. We introduce a general template for the detailed description of fission fragment properties. It is based on the careful analysis of the scission point, using both advanced topological methods and recently proposed quantum many-body techniques. We conclude that an accurate prediction of fission fragment properties at low incident neutron energies, although technologically demanding, should be within the reach of current nuclear density functional theory., Comment: 20 pages, 18 figures, 2 tables; Submitted to Physical Review C; Second revised version after comments by the referee

Nuclear Theory - Abstract
Understanding the mechanisms of induced nuclear fission for a broad range of neutron energies could help resolve fundamental science issues, such as the formation of elements in the universe, but could have also a large impact on societal applications in energy production or nuclear waste management. The goal of this paper is to set up the foundations of a microscopic theory to study the static aspects of induced fission as a function of the excitation energy of the incident neutron, from thermal to fast neutrons. To account for the high excitation energy of the compound nucleus, we employ a statistical approach based on finite-temperature nuclear density functional theory with Skyrme energy densities, which we benchmark on the 239 Pu(n,f) reaction. We compute the evolution of the least-energy fission pathway across multidimensional potential energy surfaces with up to five collective variables as a function of the nuclear temperature, and predict the evolution of both the inner and outer fission barriers as a function of the excitation energy of the compound nucleus. We show that the coupling to the continuum induced by the finite temperature is negligible in the range of neutron energies relevant for many applications of neutron-induced fission. We prove that the concept of quantum localization introduced recently can be extended to T > 0, and we apply the method to study the interaction energy and total kinetic energy of fission fragments as a function of the temperature for the most probable fission. While large uncertainties in theoretical modeling remain, we conclude that finite-temperature nuclear density functional may provide a useful framework to obtain accurate predictions of fission fragment properties., Comment: 18 pages, 12 figures, 3 tables; Submitted to Physical Review C; Second revised version after comments by the referee corrects some minor errors in the presentation of the localization method

The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) is a double-sided Time Projection Chamber (TPC) with micromegas readout designed to measure the energy-dependent neutron-induced fission cross sections of the major and minor actinides with unprecedented accuracy. The NIFFTE project addresses the challenge of minimizing major sources of systematic uncertainties from previous fission chamber measurements such as: target and beam non-uniformities, misidentification of alpha and light charged particles as fission fragments, and uncertainties inherent to the reference standards used. In-beam tests of the NIFFTE TPC at the Los Alamos Neutron Science Center (LANSCE) started in 2010 and have continued in 2011, 2012 and 2013. An overview of the NIFFTE TPC status and performance at LANSCE will be presented., Comment: Prepared for JINST as proceeding of the MPGD13 Conference

Physics - Instrumentation and Detectors ,Nuclear Experiment - Abstract
The general properties needed in targets (sources) for high precision, high accuracy measurements are reviewed. The application of these principles to the problem of developing targets for the Fission TPC is described. Longer term issues, such as the availability of actinide materials, improved knowledge of energy losses and straggling and the stability of targets during irradiation are also discussed.

- Abstract
OBJECTIVES: To assess the use of NHMRC Indigenous research guidelines by Australian researchers and the degree of Aboriginal and Torres Strait Islander governance and participation in Indigenous health research. DESIGN, SETTING, PARTICIPANTS: Cross-sectional survey of people engaged in Indigenous health research in Australia, comprising respondents to an open invitation (social media posts in general and Indigenous health research networks) and authors of primary Indigenous health research publications (2015-2019) directly invited by email. MAIN OUTCOME MEASURES: Reported use of NHMRC guidelines for Indigenous research; reported Indigenous governance and participation in Indigenous health research. RESULTS: Of 329 people who commenced the survey, 247 people (75%) provided responses to all questions, including 61 Indigenous researchers (25%) and 195 women (79%). The NHMRC guidelines were used "all the time" by 206 respondents (83%). Most respondents (205 of 247, 83%) reported that their research teams included Indigenous people, 139 reported dedicated Indigenous advisory boards (56%), 91 reported designated seats for Indigenous representatives on ethics committees (37%), and 43 reported Indigenous health research ethics committees (17%); each proportion was larger for respondents working in Indigenous community-controlled organisations than for those working elsewhere. More than half the respondents reported meaningful Indigenous participation during five of six research phases; the exception was data analysis (reported as apparent "none" or "some of the time" by 143 participants, 58%). CONCLUSIONS: Indigenous health research in Australia is largely informed by non-Indigenous world views, led by non-Indigenous people, and undertaken in non-Indigenous organisations. Re-orientation and investment are needed to give control of the framing, design, and conduct of Indigenous health research to Indigenous people.

The primary objective was to (a) test the effectiveness of an Exercise Is Medicine® on Campus (EIM-OC) program in a university setting and (b) compare the baseline levels of physical activity, mental health, and physical health with post-EIM-OC levels. Referred and consenting students (n = 9) participated in a 12-week program. At pre- and postprogram, participants completed measures of current health behaviors, obstacles to physical activity, health goals, physical activity history, biometric screening (resting heart rate, blood pressure (BP), waist-to-hip ratio, body composition percentage via bioelectrical impedance, cardiovascular and muscular endurance baseline, and flexibility), perceived stress, and self-compassion. All of the participants adhered to 100% of the program. Participants experienced a decrease in resting heart rate, body composition, and BP and an increase in sleep, physical activity, and self-compassion. The program will be implemented with a larger sample of referred students with the goal of reducing risk or prevalence of chronic disease. [ABSTRACT FROM AUTHOR]

Background: The objective of this study was to assess the efficacy of an Exercise is Medicine on Campus® program on university student biometrics and muscular endurance. It was hypothesized that participants in the 12-week program would experience significant improvements in body mass index, blood pressure, body fat percentage, waist circumference, and muscular endurance. Methods: To be eligible for the program, participants must have met two of the three criteria: (1) blood pressure over 140 and/or 90 (3 consecutive measurements over 2 weeks), (2) BMI over 30, and/or (3) diagnosed chronic condition or currently taking medication for chronic condition. Participants engaged in six bi-weekly exercise instructional meetings that lasted approximately 30 minutes in length. Participants completed measures of resting heart rate, waist-to-hip ratio, body composition percentage via bioelectrical impedance, and muscular endurance before and after the program. Results: Although not statistically significant, there was a decrease in BMI, blood pressure, body fat percentage, and waist circumference from pre- to post-program. Two-tailed t-tests revealed significant improvements in squats ( P = .04), pushups ( P = .05), and curl-ups ( P = .03) from pre- to post-program. Conclusion: The results are discussed in terms of current research and future university campus application.

Individuals may struggle to engage in regular physical activity because of self-regulatory failure and a lack of an exercise identity. One promising mechanism that has the potential to improve self-regulation of exercise is self-compassion. The purpose of this study was to test the relationship between self-compassion, self-regulation of exercise, and exercise identity. Participants included 1043 adults from across the USA (59.10% female; 40.30% male). Participants completed the self-compassion scale, exercise self-regulatory efficacy, and the exercise identity scale. Males reported significantly greater exercise identity (M =41.66, SD = 13.83) than females (M = 36.39, SD = 14.94). There was not a significant difference between gender for self-compassion (p = .07). Furthermore, males reported significantly greater exercise self-regulatory efficacy across all categories when compared to females. There was a statistically significant correlation between all outcome variables. Finally, a linear regression was used to determine the predictive value of exercise self-regulation and self-efficacy in predicting exercise identity in males and females. The variables accounted for 28% of the variance in exercise identity in males and 27% of the variance in females.
