The Nature of High-frequency Oscillations Associated with Short-lived Spicule-type Events
Authors: Shetye Juie , Verwichte Erwin , Stangalini Marco , Doyle J. G.
Published: October 2021

We investigate high-resolution spectroscopic and imaging observations from the CRisp Imaging SpectroPolarimeter (CRISP) instrument to study the dynamics of chromospheric spicule-type events. It is widely accepted that chromospheric fine structures are waveguides for several types of magnetohydrodynamic (MHD) oscillations, which can transport energy from the lower to upper layers of the Sun. We provide a statistical study of 30 high-frequency waves associated with spicule-type events. These high-frequency oscillations have two components of transverse motions: the plane-of-sky (POS) motion and the line-of-sight (LOS) motion. We focus on single isolated spicules and track the POS using time–distance analysis and in the LOS direction using Doppler information. We use moment analysis to find the relation between the two motions. The composition of these two motions suggests that the wave has a helical structure. The oscillations do not have phase differences between points along the structure. This may be the result of the oscillation being a standing mode, or that propagation is mostly in the perpendicular direction. There is evidence of fast magnetoacoustic wave fronts propagating across these structures. To conclude, we hypothesize that the compression and rarefaction of passing magnetoacoustic waves may influence the appearance of spicule-type events, not only by contributing to moving them in and out of the wing of the spectral line but also through the creation of density enhancements and an increase in opacity in the Hα line.
Do Coronal Loops Oscillate in Isolation?
Authors: Hindman Bradley W. , Jain Rekha
Published: October 2021

Images of the solar corona by extreme-ultraviolet telescopes reveal elegant arches of glowing plasma that trace the corona’s magnetic field. Typically, these loops are preferentially illuminated segments of an arcade of vaulted field lines and such loops are often observed to sway in response to nearby solar flares. A flurry of observational and theoretical effort has been devoted to the exploitation of these oscillations with the grand hope that seismic techniques might be used as probes of the strength and structure of the corona’s magnetic field. The commonly accepted viewpoint is that each visible loop oscillates as an independent entity and acts as a one-dimensional wave cavity for magnetohydrodynamic kink waves. We argue that for many events, this generally accepted model for the wave cavity is fundamentally flawed. In particular, the 3D magnetic arcade in which the bright loop resides participates in the oscillation. Thus, the true wave cavity is larger than the individual loop and inherently multidimensional. We derive the skin depth of the near-field response for an oscillating loop and demonstrate that most loops are too close to other magnetic structures to oscillate in isolation. Further, we present a simple model of a loop embedded within an arcade and explore how the eigenmodes of the arcade and the eigenmodes of the loop become coupled. In particular, we discuss how distinguishing between these two types of modes can be difficult when the motions within the arcade are often invisible.

Published: October 2021

BACKGROUND: A report from the West Sumatra Provincial Health Office in December 2017 showed increase in the percentage of overweight and obese children in the city of Padang. In 2014, overweight children amounted to 4.86% and an increase in 2016 to 6.44%.

AIM: This study aimed to determine the most dominant risk factors affecting the incidence of obesity in adolescents in Padang City.

MATERIALS AND METHODS: This study was conducted on 484 respondents from 4 (four) schools, namely SMPN 26, SMPIT Adzkia, SMAN 3, and SMA Adabiah Padang in December 2019-February 2020. Data analysis used the Chi-square test and multiple logistic regression tests.

RESULTS: The multivariate analysis results showed that adolescents’ eating behavior variable was the most dominant factor affecting adolescents’ incidence of obesity with a significance value of p < 0.05 and Exp (B) 14.11. These results showed that adolescents who behave eat poorly at 14.11 times, have the risk of obesity more than adolescents who eat well.

CONCLUSIONS: Adolescent eating behavior variables can predict the incidence of obesity in adolescents together with adolescent physical activity variables, adolescent attitudes, and adolescent knowledge.

Authors: Erlyani Neka , Suhariadi Fendy
Published: October 2021

Background: The study of readiness to change in the context of the University is needed in a situation to prepare for the 4.0 industrial revolution at the University which demands preparation in facing the VUCA era. The university is also in danger of being disrupted if it does not immediately make changes and adjustments to its role in the world of education. therefore readiness for change is the key for organizations to respond quickly and successfully to change. Methods: review the literature with a literature search strategy through publish or perish (the keywords used are readiness to change, universities, tertiary institutions). Results: 96 journal articles were found in publish or perish (step 1). The author manually screened the titles for inclusion and exclusion criteria to obtain 15 articles (step 2). All articles were subjected to an abstract review for screening according to criteria. From the results of the final selection, 11 reviewed journal articles were obtained. Conclusion: Acceptance and readiness to change is an important part of the organization especially the University which requires immediate attention. Need to be open to changes made before preparing for change. Alignment of the organization's vision and mission with employees' personal needs to be created by communicating messages of change so that they tend to have a positive attitude towards organizational change. Besides, trust in management proved to be important in implementing strategic decisions and an important determinant of employee openness to change.   Keywords: Readiness to Change, University, Campus
The Impact of Luteinizing Hormone/Chorionic Gonadotropin Hormone Receptor Gene Polymorphism rs68073206 in Men with Non-obstructive Azoospermia: A Case-control Study
Authors: Ali Abdul-Rahim A. , Abdul-Rasheed Omar F. , Al-Kawaz Ula M.
Published: October 2021

Background: The functional consequences of the luteinizing hormone/chorionic gonadotropin hormone receptor (LHCGR) gene single nucleotide polymorphism (rs68073206) on male infertility in patients with non-obstructive azoospermia (NOA) is not clear.
Objective: To examine whether the presence of LHCGR gene; rs68073206 single nucleotide polymorphisms (SNPs) can be associated with incidence of non-obstructive azoospermia.
Materials and methods: A case-control study comprised of a total of 70 unrelated Iraqi infertile men with non-obstructive azoospermia (zero sperm in semen) whose were on two groups: Group I that were diagnosed to have NOA but didn’t receive infertility treatment yet (33 patient with age of 31.58±1.059 year) and group II that were receiving injectable gonadotropin treatment (37 patient with age of 33.46±1.173 year). In addition to 34 age and BMI matched healthy fertile normozoospermic men (according to the parameters of WHO, 2010). The study population was genotyped by TaqMan assay for LHCGR gene single nucleotide polymorphism (rs68073206). The level of each hormone was estimated by immunoassay technique while the sperm analyses were conducted in accordance with the World Health Organization criteria.
Results: The study revealed a statistically significant higher hormonal level of serum inhibin B in infertile group I patients with wild GG genotype (246.445±224.106 pg/ml), and the p-value is (0.0439) as compared to that hormone levels of GT and TT genotypes carriers that were (85.969±71.685 pg/ml) and (56.420±23.988 pg/ml) respectively. ). The genotyping variations of patients, whether carrying the homozygous GG, heterozygous GT or homozygous TT genotype, did not reveal a statistically significant difference in distribution as compared to control individuals.
Conclusions: The LHCGR gene rs68073206 polymorphisms in our population having non-obstructive azoospermia can be suggested to have a modulating potential in variable gonadotropin sensitivity. The detected non-significant difference in genotypic prevalence can be attributable to the limited sample size.

Published: October 2021

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2, has caused more than 13 million cases. Until now, there is no very efficient treatment for COVID-19. There needs to be government support in socializing the COVID vaccine, one of which is the Mall Orang Sehat (MOS) innovation for healthy people, which aims to make people believe in vaccines.

AIM: The purpose of this study was to determine the relationship between policy innovations in the MOS area of healthy people and the willingness of the community to be vaccinated.

METHODS: The research method in this study uses a cross-sectional study design, with a sample of 200 using a stratified random sampling technique, with validated question instruments regarding the statement of respondents being willing to be vaccinated or not, the analysis in this study using Chi-square.

RESULTS: The results of this study indicate that there is a relationship between MOS policy innovation and patient’s willingness to be vaccinated, as evidenced by the results of SPSS p 0.000 < 0.05 which means that there is a relationship between variable 1 and variable 2.

CONCLUSIONS: The COVID-19 vaccine is the government’s effort in tackling the COVID-19 pandemic. With this health education based (Healthy People Mall) it has been proven to be able to influence the public in knowing the effects and impacts of COVID-19 so that people are willing to be vaccinated.
Sedation-Led chEmotherapy Evades Pain (S.L.E.E.P.)
Authors: Cirillo Marco
Published: October 2021

Chemotherapy and other invasive therapies are often limited by side effects, pain and negative experiences that can limit adherence to the therapy itself. Such negative components add to the patient's depressive state due to the disease. This research project proposes the use of deep sedation during chemotherapy sessions or other disabling therapies in the treatment of tumors or other severe diseases. The proposed protocol provides for an ad hoc hospitalization which could be during the night, during the day or limited to a few hours. Administration during sleep eliminates the memory and the negative impact the treatment has on the rest of the patient's daily life. This approach also agrees with the evidence of the circadian rhythm of cellular repair processes, which is greater at sunrise and sunset and linked to a good quantity and quality of sleep. In conclusion, this project aims to reduce the negative impact and increase the adherence to and efficacy of the therapy itself.
Healthy People 2020 Objectives for Violence Prevention and the Role of Nursing
Authors: Simon Thomas , Hurvitz Kimberly
Published: October 2021

Violence, including child maltreatment, youth violence, intimate partner violence, and sexual violence, is a significant public health problem in the United States. A public health approach can help providers understand the health burden from violence, evaluate evidence for prevention strategies, and learn where to turn for information about planning and implementing prevention strategies for this preventable problem. For the past three decades, the U.S. Department of Health and Human Services has published “Healthy People” objectives for the next decade. The Healthy People 2020 initiative includes 13 measurable objectives related to violence prevention, one of which was selected as a Healthy People 2020 Leading Health Indicator. Progress to achieve these objectives can save thousands of lives, reduce the suffering of victims and their families, and decrease financial cost to the law enforcement and healthcare systems. The role that nurses can and do play in violence prevention is critical and extends beyond just caring for victims to also include preventing violence before it happens. This article summarizes the violence prevention objectives in Healthy People 2020 and the resources for prevention available to support nurses and others as they move prevention efforts forward in communities to stop violence before it starts.

This article discusses current challenges in midwifery clinical practice and education and proposes possible solutions. Midwifery clinical challenges include restrictive legislation and business-related barriers, including but not limited to physician supervision restrictions, prescriptive authority, out-of-hospital birth legislation, and third party reimbursement. Educational challenges highlighted include the current healthcare climate’s influence on midwifery education, the contribution of clinical sites and preceptors, and the benefits of midwifery education.
Entre éducation populaire et scolaire, une histoire croisée des acteurs de l’école
Authors: Netter Julien
Published: October 2021

Les pratiques des différents personnels encadrant aujourd’hui l’activité des enfants à l’école découlent d’une double histoire, celle de l’éducation populaire et de l’enseignement scolaire. Cet article vise à en retracer les grandes étapes, à partir de quatre mouvements principaux : la constitution d’un lien original fort entre l’école républicaine et le mouvement laïque, l’émergence d’une nouvelle idée de l’éducation populaire après 1945 portée par des enseignants militants, la disjonction des mouvements d’éducation populaire et de l’école dans les années 1970 parallèle à la transformation des pratiques d’enseignement, et enfin la territorialisation des liens entre école et « nouvelle » éducation populaire.
Ludothécaires et champ professionnel du jeu
Authors: Hernandez Yannick , Rubi Stéphanie , Tozzi Pascal
Published: October 2021

Depuis 1968, les ludothèques s’inscrivent dans les politiques territoriales dédiées à la jeunesse, l’enfance, la culture. La progressive professionnalisation du métier de ludothécaire s’accompagne de la défense d’une juridiction dans un espace social concurrentiel. Ce groupe professionnel, jouant de diverses politiques intersectorielles et dépendant d’institutions de tutelle de plus en plus inscrites dans des dynamiques d’évaluation et d’efficience, fait face à des dilemmes, notamment celui de préserver « le jeu pour le jeu » – au cœur de leur référentiel professionnel – tout en faisant valoir le caractère plurigénérationnel et les bénéfices sociaux et éducatifs de leur action, surtout auprès des enfants et des jeunes.

Published: October 2021

Des phénomènes sociaux intriqués touchant l’action publique et les difficultés de parcours transforment le travail de professionnels intervenant auprès des jeunes en situation de vulnérabilité. L’article analyse les manières dont ces intervenants jonglent quotidiennement avec de nouvelles prescriptions et leurs conceptions de leur métier. Les résultats, issus d’entretiens auprès d’intervenants français et québécois, mettent en lumière des injonctions paradoxales qui concernent à la fois les objectifs, les référentiels de leur intervention, leurs principes de professionnalité, et leurs marges de manœuvre dans des cadres gestionnaires contraints.
Researching Uyghur spirituality, a conversation with Alexandre Papas
Authors: Papas Alexandre , Mijit Mukaddas
Published: October 2021

L’identité religieuse des Ouïghours, des Kazakhs et des autres peuples turcs vivant dans la Région Ouïghoure est devenue, au fil des années, l’un des motifs officiels de la politique répressive du gouvernement chinois. Les activités religieuses sont considérées comme arriérées, incompatibles avec la Chine moderne. Cette rhétorique a mené à l’interdiction de plupart d’activité en lien avec l’Islam. Cet entretien avec l’historien Alexandre Papas remet en cause la conception établie de la religiosité ouïghoure. En discutant de la vie et de la contribution littéraire de quelques poètes soufis vagabonds tels que Mashrab, Zalîlî et Nidâ’î, cette conversation aborde l’importance des pratiques spirituelles dans la région ouïghoure et leurs origines diverses.
Contraintes sur la liberté académique en République populaire de Chine : un problème transnational
Authors: Frangville Vanessa
Published: October 2021

L’internationalisation accélérée de l’éducation supérieure en Chine depuis les années 2000 a été perçue et soutenue avec enthousiasme par de nombreuses universités à travers le monde. Toutefois, loin de participer à la libéralisation du système politique ou de poser les garanties d’une liberté académique, cette mondialisation de l’éducation supérieure a en fait résulté dans la banalisation de formes de répression par l’État chinois au-delà de ses frontières. Cet article propose dans un premier temps d’examiner les relations entre l’État et l’enseignement supérieur en Chine contemporaine. Dans un second temps, on reviendra sur les diverses formes de violation de la liberté académique sous le gouvernement de Xi Jinping, qui affectent l’ensemble de la communauté universitaire, y compris les étudiants. La dernière partie expose les stratégies insidieuses employées par l’État chinois pour interférer dans la production scientifique internationale. Le renforcement de l’autoritarisme sous Xi a marqué un tournant dans la surveillance des chercheurs dans et en dehors de la Chine, soutenue par une technologie avancée et des réseaux d’influence étendus, établissant ainsi une transnationalisation des menaces à la liberté académique.
La Recherche et l’Innovation en France
Authors: Ollivier Anne-Cécile
Published: October 2021

Le « financement sur projet » apparaît, au niveau international, comme un mécanisme de plus en plus utilisé par les pouvoirs publics pour soutenir les activités de recherche, de développement et d’innovation menées par les acteurs publics et privés. Les objectifs auxquels il est supposé répondre sont variés : optimiser l’usage des fonds publics, promouvoir des sujets de recherche « stratégiques », favoriser l’interdisciplinarité ou les partenariats public-privé… Malgré les nombreuses vertus attribuées à l’instrument, la montée en puissance de ce type de financement ne va pourtant pas sans susciter des controverses, tout particulièrement en France. Ce chapitre a pour objectif de porter un double regard, à la fois quantitatif et qualitatif, sur ce sujet. Il propose dans un premier temps une mesure du poids de l’instrument « financement sur projet » dans les crédits publics de soutien à la RDI, en comparant la France à d’autres pays de l’OCDE. Cette mesure place a priori la France parmi les plus petits utilisateurs du financement sur projet. Dans un deuxième temps, toutefois, le texte explore la nécessaire distinction entre financement sur projet et activité sur projet : le principe de couverture partielle du coût des projets, en France, aboutit en effet à ce que la part d’activité sur projet soit plus importante que la part de financement sur projet. D’autres particularités françaises sont relevées, telles que la place importante des appels à projets collaboratifs, qui impliquent un montage plus lourd et une réduction de la dotation de chaque partenaire. Ces modalités spécifiques contribuent à expliquer le paradoxe d’un instrument dont l’usage apparemment limité (par rapport aux financements « récurrents ») est pourtant perçu par les opérateurs de recherche comme excessif au regard des coûts qu’il entraîne, en temps et en argent. Ce chapitre rappelle que le financement sur projet est un outil dont on peut choisir les caractéristiques. L’important est que ce choix soit fait en fonction d’objectifs clairement définis, explicites et collectivement assumés. Ce n’est pas suffisamment le cas dans l’état actuel des pratiques françaises.
La Recherche et l’Innovation en France
Authors: Bitard Pierre
Published: October 2021

Trois ans après l’obtention de leur diplôme, les docteurs affichent, en France, un taux de chômage de 10 %, taux deux fois plus élevé que celui des masters ingénieur. Cette mauvaise performance s’explique notamment par la réticence à l’embauche et la longue durée de probation exigée avant un emploi stable. Renforcer la confiance dans les compétences des docteurs passe par un travail impliquant les parties prenantes : docteurs et doctorants, financeurs et intermédiaires, formateurs et employeurs. Un rôle central revient évidemment aux Écoles doctorales, qui ne disposent pas toutes de moyens comparables. Mais elles ne sont pas les seules en cause. Les suggestions faites ici sont des reprises de comportements vertueux déjà à l’œuvre, ou un rappel à un ordre supérieur (à l’échelon européen par exemple). Ce travail en cours les synthétise et des discussions collectives suivront pour envisager des généralisations ; l’harmonisation et la mutualisation recommandées portent sur la sélection à l’entrée, les voies d’implication des encadrants, l’offre de formation des Écoles doctorales et leur capacité d’animation, l’implication des directions des ressources humaines, et la mutualisation de l’acquisition et du traitement des données de suivi des docteurs.
André de Richaud, un poète en revues
Authors: Simonelli Jacques
Published: October 2021

Pourquoi proposer un itinéraire d’André de Richaud à travers revues et périodiques ? C’est que ses publications dans les supports les plus variés sont représentatives de l’ensemble de son œuvre – poésie, nouvelles, romans, théâtre, autobiographie et chroniques (qui révèlent un Richaud provocant, tendre et moqueur, paradoxal toujours). La courbe de ses contributions reflète les fluctuations de sa vie, des succès précoces des années trente à la floraison de nouvelles de l’immédiate après-guerre et aux années difficiles d’après 1950 où la nécessité l’oblige à multiplier les textes écrits à la hâte et à réutiliser des récits déjà publiés dans des périodiques de moins en moins prestigieux. Ses anciens amis se détournent ; ainsi Jean Ballard des Cahiers du Sud , déjà réticent devant ses « Marges » de 1952, lui refuse-il en 1953 des « Pages trouvées dans une poubelle » avant de rompre avec lui en 1960, par une lettre assez violente. Notre bibliographie, la plus complète à ce jour, n’est sûrement pas exhaustive. Nous espérons qu’elle suscitera de nouvelles découvertes.
Global $ C^2 $-estimates for smooth solutions to uniformly parabolic equations with Neumann boundary condition

Published: October 2021

In this paper, we establish global \begin{document}$ C^2 $\end{document} a priori estimates for solutions to the uniformly parabolic equations with Neumann boundary condition on the smooth bounded domain in \begin{document}$ \mathbb R^n $\end{document} by a blow-up argument. As a corollary, we obtain that the solutions converge to ones which move by translation. This generalizes the viscosity results derived before by Da Lio.
Parameterized splitting theorems and bifurcations for potential operators, Part I: Abstract theory
Authors: Lu Guangcun
Published: October 2021

This is the first part of a series devoting to the generalizations and applications of common theorems in variational bifurcation theory. Using parameterized versions of splitting theorems in Morse theory we generalize some famous bifurcation theorems for potential operators by weakening standard assumptions on the differentiability of the involved functionals, which opens up a way of bifurcation studies for quasi-linear elliptic boundary value problems.
Yamabe systems and optimal partitions on manifolds with symmetries
Authors: Clapp Mónica , Pistoia Angela
Published: October 2021

We prove the existence of regular optimal $ G $-invariant partitions, with an arbitrary number $ \ell\geq 2 $ of components, for the Yamabe equation on a closed Riemannian manifold $ (M,g) $ when $ G $ is a compact group of isometries of $ M $ with infinite orbits. To this aim, we study a weakly coupled competitive elliptic system of $ \ell $ equations, related to the Yamabe equation. We show that this system has a least energy $ G $-invariant solution with nontrivial components and we show that the limit profiles of its components separate spatially as the competition parameter goes to $ -\infty $, giving rise to an optimal partition. For $ \ell = 2 $ the optimal partition obtained yields a least energy sign-changing $ G $-invariant solution to the Yamabe equation with precisely two nodal domains.

The purpose of this manuscript was to design a better method for recovery from rhegmatogenous retinal detachment (RRD) surgery. We attempted to achieve this by designing a helmet that can manipulate intraocular magnetic nanoparticles (MNPs) and create a magnetic tamponade, eliminating the need for postoperative head positioning. A simulated analysis was developed to predict the pattern of magnetic force applied to the magnetic nanoparticles by external magnetic field. No participants were involved in this study. Instead, magnetic flux and force data for three different helmet designs were collected using virtual simulation tools. A prototype helmet was then constructed and magnetic flux and force data were recorded and compared to virtual data. For both virtual and physical scenarios, magnitude and direction of the resulting forces were compared to determine which design created the controlled direction and strongest forces into the back of the eye. Of the three virtual designs, both designs containing a visor had greater force magnitude than magnet alone. Between both designs with visors, the visor with bends resulted in forces more directed at the back of the eye. The physical prototype helmet shared similar measurements to virtual simulation with minimal percent error (Average = 5.47%, Standard deviation = 0.03). Of the three designs, the visor with bends generated stronger forces directed at the back of the eye, which is most appropriate for creating a tamponade on the retina. We believe that this design has shown promising capability for manipulating intraocular MNPs for the purpose of creating a tamponade for RRD.

Map-based neuronal models have received much attention due to their high speed, efficiency, flexibility, and simplicity. Therefore, they are suitable for investigating different dynamical behaviors in neuronal networks, which is one of the recent hottest topics. Recently, the memristive version of the Rulkov model, known as the m-Rulkov model, has been introduced. This paper investigates the network of the memristive version of the Rulkov neuron map to study the effect of the memristor on collective behaviors. Firstly, two m-Rulkov neuronal models are coupled in different cases, through electrical synapses, chemical synapses, and both electrical and chemical synapses. The results show that two electrically coupled memristive neurons can become synchronous, while the previous studies have shown that two non-memristive Rulkov neurons do not synchronize when they are coupled electrically. In contrast, chemical coupling does not lead to synchronization; instead, two neurons reach the same resting state. However, the presence of both types of couplings results in synchronization. The same investigations are carried out for a network of 100 m-Rulkov models locating in a ring topology. Different firing patterns, such as synchronization, lagged-phase synchronization, amplitude death, non-stationary chimera state, and traveling chimera state, are observed for various electrical and chemical coupling strengths. Furthermore, the synchronization of neurons in the electrical coupling relies on the network's size and disappears with increasing the nodes number.
Potential molecular link between the β-amyloid precursor protein (APP) and hypoxanthine-guanine phosphoribosyltransferase (HGprt) enzyme in Lesch-Nyhan disease and cancer

Lesch-Nyhan disease (LND) is a rare X-linked inherited neurogenetic disorders of purine metabolic in which the cytoplasmic enzyme, hypoxanthine-guanine phosphoribosyltransferase (HGprt) is defective. Despite having been characterized over 60 years ago, however, up to now, there is no satisfactory explanation of how deficits in enzyme HGprt can lead to LND with the development of the persistent and severe self-injurious behavior. Recently, a role for epistasis between the mutated hypoxanthine phosphoribosyltransferase 1 (HPRT1) and the β-amyloid precursor protein (APP) genes affecting the regulation of alternative APP pre-mRNA splicing in LND has been demonstrated. Furthermore, there were also some reported cases of LND developing thrombosis while APP is an important regulator of vein thrombosis and controls coagulation. Otherwise, the surface expression of HGprt enzyme was also observed in several somatic tissue cancers while APP and the APP-like protein-2 (APLP2) are deregulated in cancer cells and linked to increased tumor cell proliferation, migration, and invasion. The present review provides a discussion about these findings and suggests a potential molecular link between APP and HGprt via epistasis between HPRT1 and APP genes affecting the regulation of alternative APP pre-mRNA splicing. As a perspective, expression vectors for HGprt enzyme and APP are constructed as described in Ref. # 24 (Nguyen KV, Naviaux RK, Nyhan WL (2020) Lesch-Nyhan disease: I. Construction of expression vectors for hypoxanthine-guanine phosphoribosyltransferase (HGprt) enzyme and amyloid precursor protein (APP). Nucleosides Nucleotides Nucleic Acids 39: 905–922), and they could be used as tools for clarification of these issues. In addition, these expression vectors, especially the one with the glycosyl-phosphatidylinositol (GPI) anchor can be used as a model for the construction of expression vectors for any protein targeting to the cell plasma membrane for studying intermolecular interactions and could be therefore useful in the vaccines as well as antiviral drugs development (studying intermolecular interactions between the spike glycoprotein of the severe acute respiratory syndrome coronavirus 2, SARS-CoV-2, as well as its variants and the angiotensin-converting enzyme 2, ACE2, in coronavirus disease 2019 (COVID-19) [43],[44], for example).

En este trabajo nos proponemos analizar las dinámicas complejas del proceso de expansión romana durante el periodo Ibérico Final, entre los siglos II-I a. C. en el área oriental de Iberia. La construcción de fortificaciones en oppida ibéricos se relacionaría con las estrategias de dominación romana de la región. Sin embargo, el proceso no fue ni lineal ni únicamente fruto de la imposición de los criterios de Roma, pues el papel de las poblaciones locales se mostró fundamental en estas dinámicas. Emplearemos la documentación reciente del Cabeço de Mariola, un oppidum ibérico del área central de la Contestania, contextualizado en las dinámicas regionales, para ofrecer los argumentos de complejas interacciones entre el poder romano y las poblaciones locales.
La fête baroque, archétype du macro-événement-spectacle
Authors: Spielmann Guy
Published: October 2021

Le projet PerformArt vise à relancer l’étude des fêtes des cours européennes à l’époque baroque, longtemps axée sur la seule recherche archivistique, en interrogeant le concept même de performance, qui est devenu une coquille plus ou moins vide dans laquelle les chercheurs de toutes les disciplines projettent leurs propres préoccupations et leurs préjugés. La notion d’“événement-spectacle”, qui implique à la fois un agir performatif et un agir spectatif à un moment précis dans le temps et dans l’espace, ouvre des perspectives nouvelles pour la recherche sur les fêtes. Une approche fondée sur l’événement jette un éclairage entièrement nouveau sur le spectacle en tant que phénomène fondamental d’interaction sociale ; inversement, l’étude des fêtes de cour nous aide à mieux comprendre les événements-spectacles. En effet, la fête de cour, qui se situe à l’intersection de la politique, du divertissement, de l’économie, de l’esthétique et de l’interaction sociale, constitue une forme très complexe d’événement-spectacle.
«Per allevare li giovani nel timor di Dio e nelle lettere»

Nello sterminato panorama della storia delle arti performative fiorenti nella Roma barocca, il teatro e lo spettacolo nel contesto dei collegi rivestono un’importanza non secondaria, non solo per i loro esiti rappresentativi – spesso per nulla inferiori agli allestimenti dei teatri e dei palazzi nobiliari – ma soprattutto per il ruolo che ricoprirono, a partire dalla regolamentazione nella Ratio studiorum gesuitica, nell’educazione morale e culturale degli allievi. Questo studio intende presentare un primo frammento della ricerca sui documenti dell’Archivio del Collegio Nazareno, finalizzata al recupero della storia materiale delle arti performative ivi praticate. Attraverso l’esame di fonti contabili e normative che disciplinavano il cerimoniale di feste, accademie e comedie, si proporrà una riflessione sul rapporto tra teatro e meccanismi di controllo cui il collegio era sottoposto.
Frammenti performativi nel “movementscape” della Roma tra Sei e Settecento
Authors: Giordano Gloria
Published: October 2021

Tra Sei e Settecento anche a Roma, come nel resto della penisola, si assiste a una convivenza di stili coreografici che, influenzandosi tra loro, arricchiscono sotto varie angolazioni il repertorio di sala e di teatro. Attraverso il prisma di una lettura in diffrazione sono stati analizzati documenti d’archivio riferiti alla formazione coreutica non professionale, svolta nei palazzi e nei collegi nobiliari, con l’intento di far emergere quei processi performativi che compongono parte del movementscape della Roma dell’epoca.

En août 1668, Flavio Chigi organisa un banquet spectaculaire dans son Casino alle Quattro Fontane pour célébrer la nouvelle famille papale, les Rospigliosi. Ce spectacle en plein air commença dans l’après-midi, avec une parade du cardinal qui défila dans la ville en carrosse, accompagné des dames Chigi et Rospigliosi, prenant ainsi symboliquement possession du territoire de Rome. Le soir, un banquet fut organisé par Carlo Fontana avec des sculptures alimentaires sophistiquées, des parfums, de la musique ainsi que des machines ingénieuses dont certaines produisaient des éclairs. Les invités et les artistes, ainsi que le jardin et la nourriture, furent littéralement mis en scène au sein d’une chorégraphie élaborée, destinée à montrer la puissance du cardinal Chigi. Pour finir, les monuments comestibles éphémères furent ingérés par les invités. Grâce à de nouveaux documents d’archives et à une approche inspirée des études de la performance et de la performativité du genre, ce chapitre jette un éclairage nouveau sur ce banquet.

Estudos têm investigado a ansiedade e a adaptação acadêmica em estudantes universitários, mas poucas pesquisas nacionais avaliaram a relação entre estas variáveis. O objetivo deste estudo foi avaliar o grau de adaptação acadêmica dos estudantes e suas relações com ansiedade e variáveis sociodemográficas e acadêmicas. Trata-se de Pesquisa de Levantamento (Survey), de corte transversal, parte de um estudo multicêntrico. Participaram 316 alunos da Universidade Federal de São João del-Rei, Universidade Federal de Ouro Preto e Universidade Federal do Triângulo Mineiro. Foram aplicados os seguintes instrumentos online: Questionário de Vivências Acadêmicas (QVA-r); Escala de Depressão, Ansiedade e Estresse (DASS-21) e Questionário sociodemográfico/acadêmico. Os resultados mostraram grau moderado de adaptação acadêmica, com maiores escores nas dimensões Carreira, Pessoal e Interpessoal e níveis moderados de ansiedade. Na regressão múltipla, maior nível de ansiedade foi preditor de menor adaptação acadêmica, nas dimensões Carreira, Estudo e Institucional. Para a dimensão Carreira, cursar Medicina também foi um fator preditor de menor adaptação. Para ansiedade, os fatores preditores foram: sexo feminino, cursar Enfermagem e ter menor idade. Esta pesquisa pode ser considerada um avanço na área, devido à carência de estudos nesta temática. Estudos futuros deverão incluir outras universidades e regiões do país.
“They Care, We Share”

The strategic importance of knowledge especially under dynamic business conditions makes it imperative to primarily understand the creation of the knowledge base. This paper employs mixed-method approach to understand the various triggers that motivate the knowledge sharing behavior of the IT employees working in Indian firms. Firstly, a qualitative study that comprised of thirteen in-depth interviews aimed to capture the participants’ understanding of, the context and the factors that trigger knowledge-sharing behavior. The fairness in performance appraisal, manager’s support, and career success were found to be the key triggers. Then, a quantitative study of 105 IT professionals examined the effect of the identified variables. Results suggested a positive relationship between perceived fairness in performance appraisal and knowledge-sharing behavior and the mediating role of career and hierarchical success between perceived fairness in performance appraisal system and knowledge-sharing behavior. The implications for both theory and practice have also been discussed in detail.
Examining Voluntary Engagement Barriers in Knowledge Sharing Practices for Supply Chain Innovation

Voluntary engagement (VE) creates a sense of coordination and harmonization to share knowledge. The eminence of knowledge sharing (KS) for supply chain (SC) innovation is undeniable to initiate development in products, services, and operations. However, KS process is undergoing challenges in sustaining KS engagement by SC partners. Hence, recent researchers call for the need to address this gap in the literature to assess VE barriers. This paper studies the causal relationship of VE barriers on two MNCs, i.e., Toyota and Suzuki, via the fuzzy DEMATEL approach. The case examination findings indicate culture's alignment as the prime cause of VE and leadership commitment has stronger interdependence. The core problems which need elimination are fear of losing the job, prominence and opportunistic behavior. The study concludes that companies need to instigate the natural attributes of employees’ VE by setting-up earnest guidelines to practice free information and knowledge flow.

Trypanosoma cruzi requires a triatomine insect vector for its life cycle, which can be complex in different enzootic scenarios, one of which is the unique transmission network in the Atlantic Forest of south-eastern Brazil. In Espírito Santo (ES) State, highly infected Triatoma vitticeps are frequently reported invading domiciles. However, triatomines were not found colonizing residences and mammals in the surrounding areas did not present T. cruzi infection. To date, the biotic and abiotic variables that modulate T. vitticeps occurrence and T. cruzi infection in ES State are still unknown. The aim of this study was to identify the environmental variables that modulate their occurrence. Local thematic maps were generated for two response variables: T. vitticeps occurrence and T. cruzi infection. The following explanatory variables were tested: climate (temperature, relative air humidity and rainfall), altitude elevation, mammalian species richness as well as soil and vegetation types. Spatiotemporal distribution patterns and correlation levels between response and explanatory variables were assessed through spatial statistics and map algebra modelling. The central and southern mesoregions presented higher T. vitticeps and T. cruzi distributions and can be considered transmission hotspots. The explanatory variables that can explain these phenomena were relative air humidity, average temperature, soil type, altitude elevation and mammalian species richness. Algebra map modelling demonstrated that central and southern mesoregions presented the environmental conditions needed for T. vitticeps occurrence and T. cruzi infection. The consideration of environmental variables is essential for understanding the T. cruzi transmission cycle. Cartographic and statistical methodologies used in parasitology have been demonstrated to be reliable and enlightening tools that should be incorporated routinely to expand the understanding of vector-borne parasite transmission.
Psychological Ownership in Athletic Training
Authors: Young Justin P. , Games Kenneth E. , Rivera Matthew J. , Eberman Lindsey E.
Published: October 2021

Context

Psychological ownership (PO) is a state in which an individual feels possession over an object, organization, or entity (eg, PO over the organization where one works, PO over the profession one serves). Understanding PO could provide insight into the “vitality of the profession” as defined in the Prioritized Research Agenda for the Athletic Training Profession.

Objective

To explore athletic trainers' (ATs') PO over their employing organizations and the athletic training profession.

Design

Cross-sectional study.

Setting

Web-based survey.

Patients or Other Participants

Clinically practicing ATs who were active members of the National Athletic Trainers' Association.

Main Outcome Measure(s)

Demographic variables, Psychological Ownership Questionnaire (POQ) scores, and Psychological Ownership Questionnaire for athletic training (POQ-AT) scores were the primary outcomes measured. Descriptive statistics were calculated for the demographic variables, POQ and POQ-AT overall scores, form scores, and dimension scores. Nonparametric tests were used to investigate differences between the POQ and POQ-AT by demographic characteristics.

Results

The ATs indicated greater PO over the athletic training profession (Z = −3.45, P = .001) than over their employing organizations. They displayed greater belongingness (Z = −9.51, P < .001) and self-identity (Z = −8.71, P < .001) and less territoriality (Z = −5.52, P < .001) and accountability (Z = −5.33, P < .001) over their profession than their organization. Those ATs who supervised others had higher overall POQ (Mann-Whitney U test = 34 372, P < .001) and overall POQ-AT (U = 36 624, P = .014) scores than ATs who did not supervise others. A difference was evident in overall POQ (Kruskal-Wallis statistical analysis H4 = 20.47, P < .001) and overall POQ-AT (H4 = 21.34, P < .001) scores by years of experience.

Conclusions

Respondents indicated greater PO over their profession than their employing organizations. They demonstrated greater self-identity and belongingness and less territoriality and accountability over the athletic training profession than over their employing organization, suggesting that they were connecting aspirations and accomplishments with the profession but connecting duty and responsibility with their organizations. Years of experience and supervisor status may play roles in the level of organizational PO.
