X-Ray AGB Stars in the 4XMM-DR9 Catalog: Further Evidence for Companions
Authors: Ortiz R. , Guerrero M. A. 
Published: May 2021

Abstract
Single AGB stars are not normally expected to be X-ray emitters due to the lack of a corona capable of powering a hot plasma. Therefore, the detection of X-ray emission in AGB stars by the ROSAT, Chandra, and XMM-Newton observatories has been interpreted as evidence for binarity. The number of X-ray-emitting AGB stars is, however, very small, and statistically sound conclusions shall be considered tentative. In this paper we aim at increasing the number of X-ray-emitting AGB stars and at providing a consistent analysis of their X-ray emission to be compared to their UV and optical properties. The XMM-Newton 4XMM-DR9 catalog has been searched for X-ray counterparts of various types of AGB stars: nearby (i.e., listed in Hipparcos), mass-losing, and S- and C-types. Seventeen X-ray counterparts of AGB stars have been found in the 4XMM-DR9. Nine of them have pointed XMM-Newton observations, whereas eight are genuine serendipitous discoveries. Together with the AGB stars detected by ROSAT, this increases the number of X-ray AGB stars to 26. Most of their X-ray spectra can be fit by the emission from an optically thin single-temperature thermal plasma with temperatures typically larger than 107 K. There is no obvious correlation between the X-ray and bolometric luminosity of these stars, but the X-ray luminosity generally increases with the amount of far-UV excess. The high temperature of some X-ray-emitting plasma in AGB stars and the correlation of their X-ray luminosity with the far-UV emission supports the origin of this X-ray emission from accretion disks around unseen companions.
La sélection des idées incrémentales et radicales : Les enseignements d’une étude de cas
Authors: Ininou Yassine , Loilier Thomas 
Published: May 2021

Cet article examine la façon dont les idées émises par les salariés d’une entreprise industrielle sont sélectionnées. Son objectif est d’apporter une compréhension fine et renouvelée de la dimension processuelle de cette étape clé du management de l’innovation et de la créativité. Pour atteindre cet objectif, il explore le processus de décision à l’œuvre au sein de l’entreprise Bosch MoP, en combinant entretiens qualitatifs (auprès de 38 acteurs du processus) et analyse des interactions argumentatives échangées au cours de 4 réunions de délibération du comité d’innovation en charge de la sélection. Les résultats montrent tout d’abord que le processus de sélection des idées diffère dans ses composants, son périmètre organisationnel et ses trajectoires selon que l’on traite des idées incrémentales ou radicales. Ces deux types d’idées font de plus l’objet d’argumentations spécifiques lors les comités d’innovation en charge de décider de leur acceptation ou de leur rejet. Les résultats montrent également que la sélection est bien un processus séquencé, modulable (selon le type d’idées émises) et mixte, où des approches logico-mathématiques et sociales viennent se compléter.

Authors: Vineyard Ashlyne Paige , Gallucci Andrew , Adair Kathleen , Oglesby Leslie , White Kristina , Wynveen Christopher 
Published: May 2021

Context
Burnout is a psychological syndrome consisting of increased emotional exhaustion (EE), depersonalization (DP), and decreased personal accomplishment (PA). To date, examinations of burnout among athletic training students (ATS) is limited.

Objective
To determine prevalence and antecedents of burnout among ATS.

Design
Cross-sectional study.

Setting
Web-based survey.

Patients or Other Participants
Students enrolled in athletic training programs (ATP).

Intervention(s)
A survey assessed demographics, stressors, and burnout measured by the Maslach Burnout Inventory–Human Services Survey.

Main Outcome Measure(s)
Multiple regression analyses were used to determine relationships between variables.

Results
A total of 725 students participated. Most respondents were undergraduates (n = 582, 80%), female (n = 518, 71%), Caucasian (n = 564, 78%), and single (n = 422, 58%). Mean burnout scores for EE, DP, and PA were 33 ± 10, 17 ± 4.5, and 39 ± 5.8, respectively. Survey responses showed that 70.8% of undergraduate and 62.9% of graduate students reported high EE. All the students (100%) in both samples reported high DP. Undergraduates pursuing internships or residencies (b = −7.69, P &lt; .001) and who were currently enrolled in non–Division I institutions (b = −2.90, P &lt; .01) had decreased EE. Increased stress revealed increased EE (overall stress: b = 3.11, P &lt; .001; social stress: b = 1.32, P &lt; .05; class stress: b = 1.45, P &lt; .05). Increases in clinical hours also related to increased EE (b = 1.49, P &lt; .001). Those pursuing internships or residencies (b = −2.10, P &lt; .05) and who were female (b = −2.10, P &lt; .05) reported decreased DP. Being married (b = 2.87, P &lt; .01), increased clinical hours (b = 0.77, P &lt; .001), and social stress (b = 0.59, P &lt; .05) resulted in increased DP. Increased PA was seen in students intending to pursue graduate education (b = 1.76, P &lt; .05) and female students (b = 1.17, P &lt; .05). Graduate students' stress levels revealed increased EE (b = 6.57, P &lt; .01) and DP (b = 0.98, P &lt; .05).

Conclusions
Differences exist between undergraduate and graduate burnout scores and associated predictors. Further research is needed to identify student responses to burnout.

Abstract.Disseminated histoplasmosis is the most frequent acquired immunodeficiency syndrome–defining illness in French Guiana. Paradoxically, central nervous system (CNS) involvement has been scarcely described. We aimed to identify CNS histoplasmosis in our territory. We conducted an observational, multicentric, descriptive, and retrospective study including patients with proven or probable CNS histoplasmosis according to the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MGS). The study population consisted of patients admitted in one of the hospitals of French Guiana between January 1, 1990 and December 31, 2019. During the study period, 390 cases of HIV-associated histoplasmosis were recorded, in which six of them had CNS infections with Histoplasma capsulatum. The male to female sex ratio was 0.25, and the median age at diagnosis was 37.5 years. The median CD4 count was 42 cells/mm3 ([IQR: 29–60]). All patients had disseminated histoplasmosis. Usual signs of meningitis were observed in three patients and focal signs in four patients. One patient had no neurological signs. The median time between the first cerebral symptoms and diagnosis was 22.4 days (IQR 9.5–36.2). Two patients died within a month after diagnosis. In conclusion, few proven CNS localizations of histoplasmosis were observed on 30-year study in French Guiana. This low proportion suggests that the documentation of CNS involvement is often not ascertained for lack of awareness of this particular presentation, and for lack of rapid and sensitive diagnostic tools.

Published: May 2021

GC-MS analysis of the n-hexane extract of Melilotus officinalis seeds revealed twelve compounds with a combined area percentage of 98.33% predominantly, (9Z,12Z)-octadecadienoic acid (20.22%, 366 ppm), 14-methylpentadecanoic acid (19.52%, 353 ppm) and (9E)-octadecenoic acid (15.94%, 289 ppm). Two compounds, namely, cis-coumaric acid-2-O-β-D-glucopyranoside (cis-melilotoside, 1) and 1,2-benzopyrone (coumarin, 2), were isolated from the MeOH extract of the seeds of M. officinalis. The structures of isolated compounds were determined by spectroscopic techniques such as NMR, UV-Vis, and FTIR. The MeOH extract of M. Officinalis was also tested for its antioxidant activity using DPPH assay. The extract showed 29.87% DPPH inhibition at concentration of 100 μg/mL.

Saraiki Province Movement in Punjab: Causes, Prospects and Challenges
Authors: Asif Muhmmad , Naazer Manzoor Ahmad , Ahmad Riaz 
Published: May 2021

Pakistan is an ethnically diverse country. Therefore, a federal system has been introduced after the independence. However, powers may not be fully decentralised to the federating units which created sense of deprivation particularly among the people of smaller provinces and less developed areas. To alleviate their concerns and grievances, the 18th Constitutional Amendment has been brought about and more autonomy has been given to the provinces. However, the amendment could not address the problems of ethnic minorities living in different provinces. This article explores the prospects of creation of a Saraiki or South Punjab Province. The article uses a qualitative research technique employing historical and descriptive methods. The data has been collected mostly from secondary sources. The findings show that Punjab is the largest province in terms of population, and it is difficult to manage its affairs efficiently from the Capital, Lahore. The provincial government faces difficulty to address the grievances of the people living in far-flung regions such as South Punjab. The growing inequalities led to the revival and intensification of the movement for the creation of Saraiki Province.

Authors: Ahmad Naveed Nawaz , Masroor Farzana 
Published: May 2021

Due to the significance of mission and vision statements (MS and VS) in academia across the world, this study aims at analysing generic patterns of MS and VS of universities from four different countries: two belonging to the native users of English language (UK and US) and the other two from non-native contexts (Pakistan and India). The purpose of the study is to investigate the rhetorical patterns in vision and mission statements to uncover structures used to establish universities’ global outreach and competitiveness in research and teaching. The data was collected from university websites and analysed through genre-based approach of Move Analysis introduced by Swales (2004) and applied on promotional genres by Bhatia (2004). The overall rhetorical structures of vision and Mission statements comprised of three moves with each move realized through further steps. The findings revealed that text of MS and VS provides the information about the university with an intended purpose of attracting the students by declaring the values, aims, obligations and strategic plans alongside establishing the aspects of global outreach and status in education and research as well as enriching the society and facilitating the individuals with the provision of best resources.
UN GIRO JURISPRUDENCIAL HISTÓRICO: EL TRIBUNAL SUPREMO ABANDONA SU DOCTRINA DE QUE EN LA FUNCIÓN PÚBLICA ADMINISTRATIVA NO HAY QUE JUSTIFICAR LOS NOMBRAMIENTOS PARA PUESTOS DE LIBRE DESIGNACIÓN
Authors: GIL CREMADES RAFAEL 
Published: May 2021

Durante décadas los magistrados de lo contencioso del Tribunal Supremo
¿salvo contadísimas excepciones¿ repitieron que quien nombraba a un funcionario para
un puesto de libre designación no tenía que explicar públicamente su elección; su acto
se justificaba por sí mismo en virtud de una presunta confianza en el candidato elegido;
incluso podía hacerlo por simples razones de afinidad política. Muy pocos estudiosos de
nuestra función pública criticaron esta doctrina que era incompatible con la Constitución y
la ley. Han tenido que transcurrir treinta años después de la Constitución y dieciséis después
de la Ley 30/1992 para que el Tribunal Supremo la abandonara del todo en 2009. Tres
años antes ya había rectificado su doctrina sobre los nombramientos discrecionales del
Consejo General del Poder Judicial. En este artículo se analizan y comentan ambos giros
jurisprudenciales.

For decades, judges of the contentious adminitrative section of the
Supreme Court ¿save for very rare execptions¿ have said that the person that appointed
a public officer for a free appointment position did not have to publically explain his/her
choice; his/her act was justified by itself according to a presumed trust on the chosen
candidate; he/she could even do it by simple affinity political reasons. Very few experts of
our public service did criticize this doctrine which was incompatible with the Constitution
and the Act. It has taken the Supreme Court over thirty years after the enactment of the
Constitution and sixteen of the Act 30/1992 to entirely abandon it in 2009. Three years
before it had already rectified its doctrine regading discretional appointments by the
General Council of the Judiciary Power. In this article both turns in caselaw are analyzed

The correlation between the serum insulin-like growth factor 1 level and body weight in children with a height less than the 10th percentile
Authors: Wen Xianglan , Tang Qiong , Yang Yican 
Published: May 2021

IntroductionThis study aimed to analyze the correlation between the serum insulin-like growth factor 1 (IGF-1) and body weight and provide some bases for the clinical judgment of the influencing factors on children's height.Material and methodsA total of 333 children with a height of less than the 10th percentile were enrolled in this study. Among these children, 212 were male and 121 were female. The age of these children ranged within 5-14-years-old. Serum IGF-1 level was detected and the Z-scores (SDS) of the children’s height, weight, and body mass index (BMI) were measured. The correlation among the factors was analyzed using Pearson’s correlation analysis.ResultsAge, body weight, body weight SDS, BMI and BMI SDS were all correlated with the serum IGF-1 level (P<0.0001). There was also a strong correlation between body weight and the serum IGF-1 level (r=0.718)and a weak correlation between the serum IGF-1 level and body weight SDS (r=0.359). BMI SDS was weakly correlated with serum IGF-1 (r=0.258). The correlation coefficients of age and BMI with serum IGF-1 were 0.622 and 0.536, respectively.ConclusionsThe correlation between body weight and the serum IGF-1 level is not high and it can provide some basis for the clinical judgment of the influencing factors on children's height. However, it is not the main factor affecting height.
Glabridin from licorice alleviates vascular inflammation
and promotes vascular remodeling of the left anterior
descending coronary artery in diabetic rat heart
Authors: Matsathit Udomlak , Khimmaktong Wipapan 
Published: May 2021

IntroductionThe aim of this study was to investigate the effects of glabridin on vascular inflammation and vascular remodeling of the left anterior
descending artery (LAD) in diabetic rat heart.Material and methodsEighty male Wistar rats were divided into five groups:
(1) control rats; (2) glabridin control rats that received diet supplemented
with glabridin (CGB); (3) diabetic rats (STZ); (4) diabetic rats that received
a supplemented with glabridin (STZ + GB) 40 mg/kg BW; and (5) diabetic
rats treated with glyburide (STZ + GR) 4 mg/kg BW. Diabetic animals were
rendered diabetic by injection of a single dose (60 mg/kg BW) of streptozotocin (STZ). After 8 weeks, the biochemical markers of oxidative stress were
assessed. The three-dimensional morphology of LAD was examined by vascular corrosion casting. Enzyme-linked immunosorbent assay was applied
to determine the expression of TNF-α and IL-1β proteins. Western blot and
immunofluorescence analysis were used to detect the expression of VEGF
and TGF-β1 secretions.ResultsThe lumen diameter of the LAD was notably smaller and stenotic.
LAD analysis revealed arterial notch and evolved irregular caliber. Moreover,
neovascularization appeared and was extensive. The Trolox equivalent antioxidant capacities and Trolox equivalent antioxidant capacity levels of heart
tissue were significantly decreased and levels of malondialdehyde were
found to be elevated in STZ rats whereas they were improved in the STZ
+ GB group. Increased expression levels of VEGF, TGF-β1, TNF-α, and IL-1β
proteins in heart tissues were observed in the STZ group. The inflammation
cytokine levels were decreased in the STZ + GB group.ConclusionsThese results revealed that glabridin was able to reduce LAD
and heart tissue damage. Glabridin can be an antioxidant and can reduce the
pathology of the LAD in terms of reducing inflammation and restoring condition of the LAD. It would be beneficial in examining the role of glabridin as
a therapeutic aim in diabetes treatment research in coronary artery disease.
O Trabalho docente: fundamentos de precarização e proletarização presentes na política nacional e seus reflexos na região dos inconfidentes-mg (1964-2017)
Authors: Silva Marcelo , Borges Glauber 
Published: May 2021

Este artigo tem como objetivo analisar a problemática da precarização e proletarização do trabalho docente no contexto político da microrregião dos Inconfidentes. Percebe-se que a docência no Ensino Básico nacional tem passado por um processo de transformação, que tem seu início pós-promulgação da LDB 4024/61 e se estende até os dias atuais. Buscou-se analisar as transformações políticas e educacionais que ocorreram no Brasil, do período ditatorial até a reforma do Estado e das políticas públicas nos anos de 1990 à 2017. Entende-se que, com a mudança no cenário político brasileiro para educação, essa influenciou e tem influenciado professores/as e futuros/as professores/as em avaliar negativamente a condição real da profissão, fato que externaliza o problema da precarização e proletarização, questão fortemente marcada em tempos de pandemia. Com base na análise bibliográfica e documental, essa análise terá como referencial metodológico o caráter qualitativo e quantitativo da produção. Entende-se que essa proposta metodológica é fundamental porque auxiliará na análise das fontes do período em questão e na produção acadêmica acerca do tema, para demonstrar o processo histórico e as medidas que possibilitaram a reformulação do trabalho docente. Para responder sobre essa transformação do ensino básico, busca-se analisar o panorama histórico da educação brasileira, no sentido de demonstrar que as mudanças nas políticas públicas impactam diretamente na realidade escolar de Mariana e Ouro Preto, no que tange a atuação dos e das professores e professoras no contexto escolar da região.
