Raman Geobarometry of Quartz Inclusions in Kyanite: Application to Quartz Eclogite from the Gongen Area of the Sanbagawa Belt, Southwest Japan
Authors: Tomioka Yuki , Kouketsu Yui , Taguchi Tomoki 
Published: February 2022

ABSTRACT
Residual pressure values of quartz inclusions in host kyanite were estimated using Raman spectroscopy and show that the quartz-inclusions-in-kyanite system can be used as a geobarometer for estimating peak metamorphic conditions. Samples of quartz eclogite, a pelitic high-pressure metamorphic rock composed mainly of garnet, omphacite, and quartz, with subordinate kyanite, were obtained for analysis from the Gongen area in the Sanbagawa metamorphic belt, southwest Japan. Residual pressure in the 236 analyzed quartz inclusions within kyanite grains varies from 0.12 to 0.76 GPa. Values are independent of inclusion size and inclusion aspect ratio, and the distribution of residual pressure within the inclusions is homogeneous, except at inclusion-host interfaces. Numerical calculations based on elastic modeling with the equations of state of quartz and kyanite were applied using the highest residual pressure value of 0.76 GPa, with the calculated isopleth being consistent with previous results obtained by conventional thermodynamic geothermobarometry. We conclude that the quartz-inclusions-in-kyanite system can be used as a reliable new Raman geobarometer.
Composition of Diamond from the 95-2 Pipe, Lake Timiskaming Kimberlite Cluster, Superior Craton, Canada
Authors: van Rythoven Adrian D. , Schulze Daniel J. , Stern Richard A. , Lai Mei Yan 
Published: February 2022

ABSTRACT
Forty-one samples of diamond from the Jurassic 95-2 kimberlite pipe in the Lake Timiskaming Kimberlite Cluster, Superior Craton, Canada, were imaged using cathodoluminescence and analyzed by secondary ion mass spectrometry and Fourier-transform infrared absorbance spectrometry to determine carbon stable isotope composition, total nitrogen abundance, and nitrogen aggregation state.
The carbon isotope compositions results (δ13CVPDB) range from –9.11 to –3.57‰, with a mean value of –5.8‰. Intra-stone variation is small (maximum ∼2.2‰, and in most individual diamond samples &lt;1‰). Nitrogen contents range from 0.5 to 2040 ppm (mean of 483 ppm). The greatest range of values in a single stone is 825 ppm. The samples are poorly aggregated in terms of nitrogen. The samples are mostly type IaA or IaAB, with a few bordering on type Ib.
Diamond growth was episodic, with nitrogen behaving highly compatibly (i.e., D = [N]diamond/[N]fluid &gt;&gt; 1). Precipitation was likely from a carbonate-rich fluid in a peridotitic (lherzolitic) environment within the mantle of the central Superior Craton. This generation of diamond growth is very similar to those reported from the Jurassic age Victor and U2 pipes of the Attawapiskat Kimberlite Cluster, and distinct from a possibly much older (&gt;1.1 Ga) generation of diamond reported in other older host rocks (T1, Wawa, Lynx, and Renard). This older generation of diamond at these other localities is also predominantly of the peridotitic (harzburgitic) paragenesis but contains far less nitrogen (although typically more aggregated as B centers) and has higher δ13CVPDB.
The younger generation of diamond formed after mantle heating during formation of the Mid-Continental Rift (ca. 1.1 Ga) destroyed any proximal prior generation(s) of diamond. Igneous activity after 1.1 Ga subsequently refertilized the cratonic mantle to a lherzolitic paragenesis in which the younger generation precipitated.
The redefinition of gunterite, Na4Ca[V10O28]·20H2O
Authors: Kampf Anthony R. , Cooper Mark A. , Hawthorne Frank C. , Hughes John M. , Nash Barbara P. , Adams Paul M. 
Published: February 2022

ABSTRACT
Gunterite was originally assigned the ideal formula Na4[H2V10O28]·22H2O. More detailed bond-valence analysis brought into question the presence of a protonated decavanadate anion, which led to the reexamination of the mineral. Infrared spectroscopy confirmed the absence of NH4. Reinterpretation of the original crystal structure data and new electron-probe microanalyses support the redefinition of gunterite as having the ideal formula Na4Ca[V10O28]·20H2O. This redefinition has been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association.
Peculiar Radio–X-Ray Relationship in Active Stars

Abstract
The empirical relationship between the nonthermal 5 GHz radio luminosity and the soft X-ray luminosity of active stellar coronae, canonically called the Güdel–Benz relationship, has been a cornerstone of stellar radio astronomy, as it explicitly ties the radio emission to the coronal heating mechanisms. The relationship extends from microflares on the Sun to the coronae of the most active stars suggesting that active coronae are heated by a flare-like process. The relationship is thought to originate from a consistent partition of the available flare energy into relativistic charges, which emit in the radio-band via the incoherent gyrosynchrotron mechanism, and heating of the bulk coronal plasma, which emits in the X-ray band via the Bremsstrahlung mechanism. Consequently, coherent emission from stellar and substellar objects is not expected to adhere to this empirical relationship, as it is observed in ultracool dwarf stars and brown dwarfs. Here we report a population of radio-detected chromospherically active stars that surprisingly follow the Güdel–Benz relationship despite their radio emission being classified as coherent emission by virtue of its high circularly polarized fraction and high brightness temperature. Our results prompt a reexamination of the physics behind the Güdel–Benz relationship, its implication for the mechanism of coronal heating and particle acceleration in active stars, and the phenomenological connection between solar and stellar flares.
Les associations d’action sociale à l’heure du management
Authors: Legros Patrick 
Published: February 2022

La professionnalisation a pour effet de transformer l’association en « entreprise associative ». Ce phénomène pose la question des modes de management et des pratiques d’encadrement à l’œuvre dans les associations. Ce texte, qui concerne précisément les associations d’action sociale en France, montre qu’elles sont aujourd’hui orientées par les pouvoirs publics vers un management où prévaut l’efficacité productive. Le management informel qui caractérisait auparavant l’encadrement associatif ne représente pas pour autant un « âge d’or » auquel il faudrait encore se référer ; d’où l’enjeu de rechercher de nouvelles marges de manœuvre entre logiques gestionnaires et spécificités associatives. Dans cette perspective, les formations au management méritent sans doute d’être repensées pour valoriser beaucoup plus les savoirs mis en œuvre par les encadrants dans leurs pratiques.
Quels engagements pour les professions sociales ?
Authors: Molina Yvette 
Published: February 2022

En France, le champ social et médico-social s’est développé pour une grande part au sein du secteur associatif. Il est marqué historiquement par ses valeurs militantes, religieuses, politiques, parallèlement à la construction et à la professionnalisation du secteur. La question que nous posons pour cette contribution est celle du rapport entre engagement personnel et engagement professionnel. Nous nous centrons sur le lien entre engagement dans la société civile et les motivations conduisant à un choix d’orientation vers les professions sociales pour les jeunes générations. Autrement dit, s’agit-il pour ces dernières d’être engagées, de partager certaines croyances politiques ou religieuses, de connaître un héritage social et familial pour expliquer les motivations vers les professions sociales ? Les résultats d’une enquête qualitative et quantitative auprès de jeunes « candidats » souhaitant s’insérer dans les formations professionnelles du travail social viennent apporter des éléments de réponse à ce questionnement.
Le théâtre musical au XXe siècle. Une expérience politique
Authors: Saroh Karine 
Published: February 2022

Au coeur de l’élan moderniste qui anime le xxe siècle, l’expression « théâtre musical » devient l’étendard d’une recherche esthétique de nouvelles formes de rencontre scénique entre le théâtre et la musique. Que l’objectif soit de moderniser l’opéra, de le remplacer, de réformer le théâtre ou de créer un nouveau genre à mi-chemin entre les deux arts, les collaborations rassemblant compositeurs, dramaturges et/ou metteurs en scène entendent présenter des œuvres actuelles, qui balaient les modèles esthétiques jusqu’alors dominants. À l’heure où les sociétés européennes sont ébranlées par les guerres mondiales et les modèles totalitaires, l’espace esthétique pluridisciplinaire du théâtre musical se révèle propice à la réflexion philosophique et à l’expérimentation de systèmes qui visent la protection et l’émancipation du politique. L’utopie artistique, qui incite à repenser les cadres formels du théâtre musical, cultive aussi des modèles d’utopie politique. Le théâtre musical devient le lieu privilégié d’une réflexion philosophique sur la pratique militante et sur les moyens de l’exercice politique, ainsi que sur l’idéal démocratique dont nous sommes aujourd’hui les héritiers.
Avenues for Sport-Related Concussion Prevention in High School Football: Effect of Limiting Collision Practices
Authors: Bretzin Abigail C. , Tomczyk Christopher P. , Wiebe Douglas J. , Covassin Tracey 
Published: February 2022

Context
Football continues to demonstrate the highest rate of sport-related concussion (SRC) in high school athletics. To mitigate the SRC risk, the Michigan High School Athletic Association (MHSAA) implemented rules aimed at reducing the number of collisions occurring in practices.

Objective
To estimate the rates of SRC in MHSAA football programs and evaluate progressive limitations to collision practices over 5 consecutive seasons.

Design
Retrospective cohort study.

Setting
Michigan high school football.

Patients or Other Participants
High school (9th–12th grade) football athletes (&gt;99% male) participating in MHSAA-sanctioned events.

Main Outcome Measure(s)
Designated administrators at each school recorded the total number of participating athletes and SRCs (defined as head injuries resulting from athletic participation that required the student-athletes to be withheld from activity after exhibiting signs, symptoms, or behaviors consistent with an SRC) in the MHSAA injury-surveillance system each season (2015–2016 through 2019–2020). Progressive limitations to collision practices occurred across the study period. We estimated athlete-exposures (AEs) as the total number of players multiplied by the total number of possible practices (11 weeks, 4 days each) or competitions (9 weeks, 1 day each) during each season. Incidence rates and rate ratios (RRs) with 95% CIs were used to compare practice and competition SRCs and each season with the most recent season.

Results
A total of 7755 football SRCs were diagnosed across the 5-year period. The overall SRC rate was 8.03 per 10 000 AEs (95% CI = 7.85, 8.21). The competition SRC rate (30.13/10 000 AEs) was higher than the practice rate (3.51/10 000 AEs; RR = 8.58; 95% CI = 8.19, 9.00). The practice SRC rate was lower in 2017–2018 (RR = 0.86; 95% CI = 0.77, 0.97), 2018–2019 (RR = 0.89; 95% CI = 0.79, 1.0), and 2019–2020 (RR = 0.83; 95% CI = 0.74, 0.94) relative to 2015–2016.

Conclusions
We found that the progressive limitations to collision practices were protective against SRCs, as the rate of SRC was lower in the 3 most recent seasons relative to 2015–2016.
Assessing Omega-3 Intake in Sport: the Brief Food Frequency Questionnaire and the Omega-3 Index in Collegiate Women Soccer Players
Authors: Essman Macy , Christifano Danielle , Sullivan Debra K. , Chalise Prabhakar , Carbuhn Aaron 
Published: February 2022

Context
Omega-3 fatty acids modulate inflammatory processes and are considered beneficial for sport populations, highlighting a need to assess omega-3 intake in a practical manner. Food frequency questionnaires (FFQs) are inexpensive, noninvasive tools aimed at evaluating nutrient intakes such as omega-3 fatty acids. In healthy adults, a tailored, brief FFQ for estimating omega-3 intake was associated with the erythrocyte omega-3 fatty acid level, a biomarker for omega-3 tissue status and indicative of intake. However, the association between a brief omega-3 FFQ and erythrocyte levels, particularly the Omega-3 Index (eicosapentaenoic acid [EPA], docosahexaenoic acid [DHA], and EPA + DHA), has yet to be explored in a sport population.

Objective
To examine the association between omega-3 intake using a brief FFQ and the Omega-3 Index in collegiate women soccer players.

Design
Cross-sectional study.

Setting
University sport team.

Patients or Other Participants
Thirty-one National Collegiate Athletic Association Division I collegiate women soccer players.

Main Outcome Measure(s)
The brief omega-3 FFQ assessed dietary omega-3 intake: DHA and EPA. The OmegaQuant blood test measured erythrocyte omega-3 fatty acid (EPA, DHA) and Omega-3 Index (EPA + DHA) levels.

Results
Brief FFQ intakes of EPA, DHA, and EPA + DHA were positively correlated with the erythrocyte EPA (r = 0.48, P = .007), DHA (r = 0.73, P &lt; .001), and Omega-3 Index (r = 0.73, P &lt; .001).

Conclusions
In a sample of collegiate women soccer players, the brief omega-3 FFQ was correlated with erythrocyte omega-3 fatty acid levels and may offer health practitioners a practical tool for assessing omega-3 intake in this collegiate sport population.

Background: Prevalence of HIV, smoking, and pulmonary infections in South Africa are high.Objectives: We investigated the role of smoking and HIV status on lung function.Methods: This is a secondary analysis of a cross-sectional study conducted in South Africa. Data included demographics, pulmonary risk factors and a spirometry test to obtain the forced expiratory volume in one second (FEV1) and the ratio of FEV1/forced vital capacity (FVC). In the initial multivariable regression analysis, the effect of smoking on pulmonary function in HIV-positive adults was assessed. The analysis was repeated, assessing the influence of HIV status on lung function in both HIV-negative and HIV-positive smokers. The models were adjusted for age, sex, body mass index (BMI), time since HIV diagnosis, antiretroviral treatment (ART) use, occupational hazards, history of tuberculosis or pneumonia, indoor smoking and the presence of an indoor fireplace during childhood.Results: This study included 524 people living with HIV (PLWH, 66.7% female, mean age 40.9 years [s.d.; 9.4]) and 79 HIV-negative smokers (77.2% male, mean age 34.4 years [s.d.: 12.1]). Of the PLWH, 118 (22.5%) were past or current smokers and 406 (77.5%) were non-smokers. Smoking was not associated with changes in the FEV1 or FEV1/FVC ratio in multivariable regression analysis. In the second analysis, HIV status was also not associated with reduced pulmonary function following adjustment for confounders.Conclusion: Neither smoking nor being HIV-positive was associated with decreased pulmonary function in this relatively young population. These findings should be confirmed in a longitudinal study, including an older population.
