Adoption of Proprietary Online Education Software Compared to Free And Open-Source Software in Indian colleges
Authors: Sehgal Shubhraj , Gupta Avinash , Singh Alka , Singh Preeti
Published: May 2022

Adoption of online learning tools is still in the nascent stage in India. Use of such tools has been sporadic and patchy at best. The Covid pandemic of 2020 forced the institutions to shut down which resulted in the sudden adoption of such software. The education market in India is dominated by free & open-source software also known as FOSS while proprietary software solutions take a back seat. This research focuses on the impacts of proprietary education software in easing the learning process for children as well as grad-students, and how these tools impact engagement and learnability. Moreover, a retrospective study of an open-source tool present in the market and the comparison of it with the proposed system have been presented. Further, an example of a proposed system of how a simple system can be created in-house and at minimal cost to serve as a proprietary solution for all online educational needs of the pupils has been demonstrated.

Authors: Ryabykh Andrey , Maslova Olga , Beznosyuk Sergey , Nikolskiy Sergey
Published: May 2022

The interaction of the superoxide radical ion O2– with the active center of Cu,Zn-superoxide dismutase was studied by computer simulation using the ORCA software package version 5.0.2. at the level of density functional theory using the PBE functional. The main characteristics for two processes of electron transfer in the catalytic cycle of deactivation of the radical ion are obtained. The variable factor in the modeling was the presence of the Zn2+ ion in the active site of the enzyme. It has been established that the presence of the Zn2+ ion contributes to a large extent only to the second electron transfer from the Cu+ ion to the protonated form of the radical ion, to the hydroperoxide radical HO2

Reviving Lenity and Honest Belief at the Boundaries of Criminal Law
Authors: Diamond John
Published: May 2022

It is a common misconception that there is a line between criminal and innocent conduct that is transparent and fixed. In fact, much of criminal law is fluid and elastic, free, if strategically applied, to label conduct as legal or illegal. In some cases, this reflects crimes that are vaguely defined or imprecise. In other cases, the prohibited conduct simply includes what is so conventionally accepted as legal that the criminal label is perceived as inapplicable until a prosecutor chooses to apply it. The problem of a fluid rather than a fixed line for criminality is that prosecutorial discretion becomes central to the application of the state's imposition of criminal sanctions. This Article illustrates, by core examples, how elastic the application of the criminal law can be. It considers remedies that will protect against both good and bad faith abuse without sacrificing the legitimate and central role of prosecutorial discretion. In particular the Article argues for a reinvigoration of the rule of lenity and for the incorporation of the English requirement of dishonesty in theft crimes.

So it is hoped that this learning model can be used as an alternative to improve students' mathematical communication skills.
Wszystkie niewidziane filmy. Długi ogon światowego kina
Authors: Stelmach Miłosz
Published: May 2022

Celem niniejszego tekstu jest zaobserwowanie – przy wykorzystaniu dostępnych statystyk wielkoskalowych – tendencji w globalnej produkcji filmowej. Punkt wyjścia dla tych dociekań stanowią szacunki rozmiarów rynku filmowego – od wolumenu produkcji światowej, przez dane dotyczące zysków z dystrybucji i sprzedanych biletów, po liczbę ekranów kinowych. W kontekście innych dostępnych informacji pozwalają one postawić tezę, że współczesną produkcję filmową w bardzo dużym stopniu definiują dwa pozornie przeciwstawne, w istocie jednak dopełniające się trendy: z jednej strony tendencja do poszerzania, demokratyzacji i rozdrobnienia filmowego świata, z drugiej zaś do jego bezprecedensowej koncentracji i dominacji kilku największych podmiotów. Efektem ich działania jest powstawanie „długiego ogona” światowego kina – coraz bardziej rozrastającego się sektora produkcji powstających na całym świecie, ale niemających rozbudowanych grup odbiorców.
Działalność producencka Studia Filmowego im. Karola Irzykowskiego w latach 1981-1989
Authors: Sowiński Emil
Published: May 2022

Studio Filmowe im. Karola Irzykowskiego zostało założone przez grupę młodych filmowców w 1981 r. w celu produkowania debiutów filmowych. Choć instytucja ta była wpisana w ramy oficjalnych struktur kinematografii, w zasadzie funkcjonowała poza nimi. Podlegała bezpośrednio Ministerstwu Kultury i Sztuki, ale jej władze (wybierana demokratycznie Rada Artystyczna składająca się z pięciu młodych twórców) mogły samodzielnie podejmować decyzje dotyczące produkcji filmowej. Dlatego też polityka Studia mogła być bardziej niezależna niż np. zespołów filmowych. W 1984 r. zmieniła się struktura organizacyjna Studia; w latach 1985-1989 utraciło ono znaczące przywileje, przez co przestało się właściwie różnić od zespołów filmowych. Miało to wpływ na działalność producencką Studia w tym okresie. Celem artykułu jest odpowiedź na pytanie, jak decyzje personalne, polityczne i instytucjonalne wpłynęły na organizację i politykę programową Studia w latach 1981-1989.

Published: May 2022

Foreign exchange risk is one of the most important components of the financial market. Like any other financial risk, it can be managed or avoided. Financial risk management requires the relevant knowledge and resources and only specialized financial institutions are engaged in doing so. Thee commercial banks do not accept foreign exchange risks, their assets and liabilities are denominated in the same currency. Therefore, it is recommended for households and businesses to avoid the currency risk.
People's behavior is different during the sharp fluctuations of exchange rates. There is no ideal tactic for behavior. However, we would like to share some basic tips to help you reduce your expected financial risks; At the same time, the undesirable attitude characteristic of the period of strong fluctuations in the course will become clearer and more preventive. We hope that the information presented in such circumstances will help you to make the right decision.

The interrelations between difference and projection and other signature operations in table algebra
Authors: Senchenko Aleksei
Published: May 2022

Currently, databases are widely used in almost all areas of human activity. For all variety of different types of databases the most common are relational (table) databases, mathematical model of which was proposed by E. Codd. From mathematical point of view, a relational database is a finite set of finite relations between different predefined sets of basic data. Table algebra introduced by V.N.~Red’ko and D.B. Buy is based on Codd’s relational algebra and significantly improves it. It formed the theoretical foundation of modern database query language. Elements of the carrier of table algebra specify relational data structures, and signature operations are based on the basic table manipulations in relational algebra and SQL-like languages. One of the most actual tasks in relational and table algebras is the problem of equivalent transformation of expressions in order to minimize or reduce them to a standard form; it is one of the stages of query optimization, and can also significantly reduce the processing time of information in relational database management systems. For the decision of this problem the interrelations between the basic table operations are used. In the present, a significant number of such interrelations have been established, most of which for the general case are performed as inclusions. The author has found criteria for the transition of some such inclusions into equalities. These criteria are expressed in terms of the active domains of the tables and are natural. In this paper, the interrelations of the difference and the projection of tables with other signature operations of table algebras: intersection, union, selection, renaming of attributes, join, saturation, active complement are considered.

Chronic Fatigue Syndrome
Authors: Berlianto Ridho , Arina Widya Murni
Published: May 2022

Background: Chronic fatigue syndrome is a collection of symptoms characterized by complaints of fatigue that lasts for at least six months or more. It can be accompanied by symptoms of low-grade fever, myalgia, arthralgia, cephalgia, and a sore throat that is sometimes accompanied by enlarged glands. The main psychological symptoms of chronic fatigue syndrome are depression and sleep disturbances.

Case Presentation: A 26-year old male patient was treated with a main complaint of feeling tired since 6 months before he was admitted to the hospital. The patient claimed that he was unable to do activities independently because he experienced extreme tiredness. He also complained of a headache that was felt when under stress and was not relieved by rest along with a stabbing-like pain that moved around throughout his body, which also does not decrease with changes in position or rest. He also has heartburn felt since 4 months ago when eating spicy foods, eating late, and especially when experiencing mental stress, which often was accompanied by nausea and vomiting. The results of his physical, laboratory and supporting examinations were all within normal limits. The patient was then diagnosed with chronic fatigue syndrome and functional dyspepsia.

Conclusion: Approaches to medical treatment of chronic fatigue syndrome can be done based on general treatment of physical and psychological symptoms experienced. In these circumstances, antidepressant drug therapy and psychotherapy such as cognitive behavioral therapy is needed. In addition, rehabilitation therapy may also be necessary because several studies show that gradual physical exercise yield significant improvement in chronic fatigue syndrome patients.
Relationship between the extent of Implementation of Kiswahili Curriculum in Secondary Schools in Vihiga County and Student Kiswahili Achievement and Attitudes Towards Kiswahili
Authors: Juma Rose , Kyalo Benjamin Wambua
Published: May 2022

Effective curriculum implementation is essential for the realisation of set objectives. This study examined the relationship between the extent of implementation of the Kiswahili curriculum in secondary schools in Vihiga County and student Kiswahili achievement and attitudes towards Kiswahili. The study used an Ex-Post Facto research design. The target population included secondary school students. Probability sampling approaches were used. Ninety-eight students from national schools were selected 105 from Extra- County schools, and 140 from County schools. Research instruments included; questionnaires, achievement tests, and an attitude scale for students. The test-retest method was used to determine the reliability of the evaluation results. Data were analysed using frequencies, means and standard deviations. ANOVA was used to test hypotheses. The study concluded that the Kiswahili curriculum was implemented to some extent in Vihiga County. Students’ performance was influenced by the extent of Kiswahili curriculum implementation. Students performed well where the curriculum was implemented to a large extent. Consequently, it was established that there was a relationship between students’ attitudes and the extent of Kiswahili curriculum implementation. Students tended to have positive attitudes towards Kiswahili, where the curriculum was implemented to a large extent. The study recommended that teachers needed to come up with new teaching methods that would focus on improving the performance of students in Kiswahili subjects. This could be achieved through regular in-service training programs that were diversified to accommodate various needs of teachers coming from different schools.
Peripheral vision in real-world tasks: A systematic review
Authors: Vater Christian , Wolfe Benjamin , Rosenholtz Ruth
Published: May 2022

Peripheral vision is fundamental for many real-world tasks, including walking, driving, and aviation. Nonetheless, there has been no effort to connect these applied literatures to research in peripheral vision in basic vision science or sports science. To close this gap, we analyzed 60 relevant papers, chosen according to objective criteria. Applied research, with its real-world time constraints, complex stimuli, and performance measures, reveals new functions of peripheral vision. Peripheral vision is used to monitor the environment (e.g., road edges, traffic signs, or malfunctioning lights), in ways that differ from basic research. Applied research uncovers new actions that one can perform solely with peripheral vision (e.g., steering a car, climbing stairs). An important use of peripheral vision is that it helps compare the position of one’s body/vehicle to objects in the world. In addition, many real-world tasks require multitasking, and the fact that peripheral vision provides degraded but useful information means that tradeoffs are common in deciding whether to use peripheral vision or move one’s eyes. These tradeoffs are strongly influenced by factors like expertise, age, distraction, emotional state, task importance, and what the observer already knows. These tradeoffs make it hard to infer from eye movements alone what information is gathered from peripheral vision and what tasks we can do without it. Finally, we recommend three ways in which basic, sport, and applied science can benefit each other’s methodology, furthering our understanding of peripheral vision more generally.
A tutorial on Bayesian single-test reliability analysis with JASP
Authors: Pfadt Julius M. , Bergh Don van den , Sijtsma Klaas , Wagenmakers Eric-Jan
Published: May 2022

The current practice of reliability analysis is both uniform and troublesome: most reports consider only Cronbach’s α, and almost all reports focus exclusively on a point estimate, disregarding the impact of sampling error. In an attempt to improve the status quo we have implemented Bayesian estimation routines for five popular single-test reliability coefficients in the open-source statistical software program JASP. Using JASP, researchers can easily obtain Bayesian credible intervals to indicate a range of plausible values and thereby quantify the precision of the point estimate. In addition, researchers may use the posterior distribution of the reliability coefficients to address practically relevant questions such as “What is the probability that the reliability of my test is larger than a threshold value of .80?”. In this tutorial article, we outline how to conduct a Bayesian reliability analysis in JASP and correctly interpret the results. By making available a computationally complex procedure in an easy-to-use software package, we hope to motivate researchers to include uncertainty estimates whenever reporting the results of a single-test reliability analysis.
The Headphone and Loudspeaker Test – Part I: Suggestions for controlling characteristics of playback devices in internet experiments
Authors: Wycisk Yves , Kopiez Reinhard , Bergner Jakob , Sander Kilian , Preihs Stephan , Peissig Jürgen , Platz Friedrich
Published: May 2022

In internet experiments on auditory perception, playback devices may be a confounding variable reducing internal validity. A procedure to remotely test multiple characteristics of playback devices does not currently exist. Thus, the main goals of this study were to (i) develop and (ii) evaluate a comprehensive, efficient, and easy-to-handle test procedure for the reliable control and identification of playback device characteristics in online experiments. Based on a counting task paradigm, the first part of the Headphone and Loudspeaker Test (HALT–Part I) was developed with which researchers can standardize sound level adjustments, detect stereo/mono playback, and assess lower frequency limits. In a laboratory study (N = 40), HALT–Part I was evaluated with four playback devices (circumaural and intra-aural headphones; external and laptop loudspeakers). Beforehand, the acoustical properties of all playback devices had been measured (e.g., sound pressure level, frequency response, total harmonic distortion). The analysis suggested that HALT–Part I has high test–retest reliability (rtt = .90 for level adjustment and rtt = .79 for stereo/mono detection) and is an efficient (3.5 minutes for completion) method to remotely test playback devices and listening conditions (sound level, stereo/mono playback). The procedure can help improve data quality in internet experiments.
War and Intelligence
Authors: Akhutin Anatoly
Published: May 2022

I ventured to think during the war. I wrote several blogs on the topic "War and Intelligence". Everything seems out of place here. War requires action (participation, protection, assistance), and thought wants concentration in peace. I am not engaged in scientific research, I just think about what I can, what I have, and what I carry with me, without referring to sources and reference books. I'm thinking about this very: how does the event of the war relate to the ability — and maybe even the duty — to think. I wrote two posts. They consider intelligence (intellectus) as a kind of responsibility. All knowledge, awareness, concepts, sciences, discursive practices, etc. — are secondary. They make sense in the primary context of responsibility. All intellectual pursuits have meaning and meaning as aspects of the answer to the question that constitutes a human being as human. This is being-in-question.
Ayuno preoperatorio: diferencias ultrasonográficas en periodos de ayuno diferentes en pacientes hospitalizados en el Hospital Santo Tomás
Authors: Carrasco Andres , Errigo Marjorie
Published: May 2022

Introducción: La principal razón, por la que surge el concepto de ayuno prolongado, en pacientes que serán sometidos a procedimientos quirúrgicos, es para disminuir el contenido estomacal, y así el riesgo o la incidencia de vómitos y broncoaspiración durante la inducción de la anestesia. Volúmenes grandes a nivel del antro gástrico, están asociados a riesgo de vómito perioperatorio. Objetivo: Comparar mediante ultrasonido la apariencia cualitativa gástrica, luego de diferentes periodos de ayuno. Metodología: Estudio prospectivo, transversal, cualitativo realizado en pacientes hospitalizados en el Hospital Santo Tomás durante los meses de julio a octubre 2020. A cada paciente se le indicó realizar un ayuno completo de 8 horas y posterior, un ayuno de 2 horas luego de una bebida con carbohidratos. Se analizaron datos demográficos (edad, sexo, peso, talla), índice de masa corporal, clasificación ASA, y la apariencia cualitativa del estómago en el ultrasonido en cada ayuno. Resultados: 92 pacientes, con predominio del sexo masculino y una media de edad de 37 años, fueron evaluados mediante ultrasonido: se observó que a las 8 horas de ayuno el 100% de los pacientes presentaban un estómago vacío (grado 0), mientras que a las 2 horas de ayuno a liquido el 67% presentó un grado 0, el 26% presentó grado 1 y el 4% presentó grado 0. Conclusiones: los periodos de más de 8 horas tienen características ultrasonográficas muy similares a los periodos de ayuno de 2 horas a líquidos, en la población de adultos jóvenes sin patologías que alteren el estómago.

Authors: Chamorro Fermina , Stocel Selvis , Ruth G De León R
Published: May 2022

Objetivos: Estimar la necesidad insatisfecha de planificación familiar con métodos modernos identificando factores relacionados en hombres de Colombia, Guatemala, Haití, Honduras y Panamá.
Métodos: Este estudio transversal utilizó datos de encuestas representativas a nivel nacional en Colombia, Guatemala, Haití, Honduras y Panamá para analizar entrevistados casados/unidos de 15-59 años con necesidades de planificación familiar. La relación de factores con la necesidad insatisfecha se probó mediante regresión logística multivariable.
Resultados: La necesidad insatisfecha era mayor en Haití (46.5%), seguido por Panamá (43.0%), Guatemala (36.8%), Honduras (21.3%) y Colombia (12.4%). Las oportunidades relativas ajustadas de necesidad insatisfecha aumentaron con la edad en todos los países; eran mayores en pertenecientes a pueblos indígenas de Colombia, Guatemala, Honduras y Panamá; en quienes vivían en hogares con menor bienestar en Guatemala, Honduras y Panamá; y en quienes informaron uniones formales en Guatemala y Honduras. Las oportunidades de necesidad insatisfecha disminuyeron con mayor escolaridad en Haití; con mayor conocimiento de métodos modernos en Guatemala y Honduras; si discutieron sobre planificación familiar con algún profesional/trabajador de salud en Haití y Panamá; y si recibieron información sobre planificación familiar en medios de comunicación en Colombia.
Conclusiones: Existen factores demográficos, socioeconómicos, de acceso a información y comportamiento relacionados con la necesidad insatisfecha. Incluir a los hombres en los programas de planificación familiar y en el desarrollo de intervenciones culturalmente aceptadas contribuiría a acelerar el logro del ejercicio responsable y voluntario del derecho a decidir si reproducirse, cuándo y con qué frecuencia.

The Ancient Globular Clusters of NGC 1291
Authors: Hixenbaugh Kyle , Chandar Rupali , Mok Angus
Published: May 2022

We present a new catalog of 81 ancient globular clusters (GCs) in the early-type spiral (SB0/a) galaxy NGC 1291. Candidates have been selected from B, V, and I band images taken with the Hubble Space Telescope, which also reveal 17 younger (τ ≲ few × 100 Myr) clusters. The luminosity function shows a peaked shape similar to that found for GC systems in other spiral and elliptical galaxies. The ancient clusters have a bimodal color distribution, with approximately 65% (35%) of the population having blue (red) colors. The red, presumably metal-rich, GCs are more centrally concentrated, as expected for a bulge population; while the blue, presumably metal-poor, GCs are more broadly distributed, consistent with expectations of a halo population. The specific frequency of GCs in NGC 1291 is higher than found previously in most spiral galaxies. However, if we consider just the blue subpopulation, we find S
N,blue = 0.50 ± 0.06, quite similar to that found for other spirals. This result supports the hypothesis of a universal population of halo GCs in spirals. The fraction of red GCs in NGC 1291, when compared with those found in other galaxies, suggests that these correlate with host galaxy type rather than with host galaxy luminosity.

FRB 180301 is one of the most actively repeating fast radio bursts (FRBs) that has shown polarization angle changes in its radio burst emission, an indication for their likely origin in the magnetosphere of a highly magnetized neutron star. We carried out a multiwavelength campaign with the FAST radio telescope and NICER X-ray observatory to investigate any possible X-ray emission temporally coincident with the bright radio bursts. The observations took place on 2021 March 4, 9 and 19. We detected five bright radio bursts with FAST, four of which were strictly simultaneous with the NICER observations. The peak flux density of the radio bursts ranged between 28 and 105 mJy, the burst fluence between 27 and 170 mJy ms, and the burst durations between 1.7 and 12.3 ms. The radio bursts from FRB 180301 exhibited a complex time domain structure, and subpulses were detected in individual bursts, with no significant circular polarization. The linear degree of polarization in the L band reduced significantly compared to the 2019 observations. We do not detect any X-ray emission in excess of the background during the 5, 10, 100 ms, 1 and 100 s time intervals at/around the radio-burst barycenter-corrected arrival times, at a > 5σ confidence level. The 5σ upper limits on the X-ray (a) persistent flux is <7.64 × 10−12 erg cm−2 s−1, equivalent to L
X < 2.50 × 1045 erg s−1 and (b) 5 ms fluence is <2 × 10−11 erg cm−2, at the radio burst regions. Using the 5 ms X-ray fluence upper limit, we can estimate the radio efficiency η

High-energy Studies of the 3HWC J1954+286 Region: Likely Gamma-Ray Detection of the Supernova Remnant G65.1+0.6
Authors: Xing Yi , Zheng Dong , Wang Zhongxiang , Zhang Xiao , Chen Yang , Xiang Guangman
Published: May 2022

We carry out high-energy studies of the region of the Galactic TeV source 3HWC J1954+286, whose location coincides with those of PSR J1954+2836 and supernova remnant (SNR) G65.1+0.6. Analyzing the GeV γ-ray data obtained with the Large Area Telescope on board the Fermi Gamma-ray Space Telescope, we are able to separate the pulsar’s emission from that of the region. Excess power-law-like emission of a ∼6σ significance level at the region is found, which we explain as arising from the SNR G65.1+0.6. Given the low-significance detection, either a hadronic or a leptonic model can provide a fit to the power-law spectrum. Considering the properties of the pulsar and the SNR, we discuss the possible origin of the TeV source, and suggest that it is likely to be the TeV halo associated with the pulsar.

Introduction: A staggering 30% of deaths in neonates are caused by preterm births. The most common cause of perinatal morbidity and mortality around the world is due to preterm births, also referred to as premature. Hence, the ability to predict preterm births would result in significantly reduced fatalities.

The likelihood of predicting a premature birth can be measured by the cervical length; however, there are other diagnostic procedures which utilize the contents of the cervico-vaginal fluid (CVF) for a more precise diagnosis. The latter also aids in detecting other pregnancy related anomalies. The phosphorylated insulin-like growth factor binding protein-1 (pIGFBP-1) is an example of a clinical biomarker which is frequently tested as it proves to be an indicator to predict preterm labour.

Aim: Thus, in this study, our aim was to evaluate the accuracy of pIGFBP-1 as a marker of preterm labour when coupled with cervical biometrics.

Materials and methods: A cross-sectional study of 32 pregnant women was conducted. The patients were split into 2 groups in which Group A consisted of those at risk of preterm labour and Group B – of women with normal and uncomplicated pregnancies. All participants were tested for pIGFBP-1 along with gathering data of transvaginal measurements of their cervical length.

Results: We found in all participants in the study a moderate association between the expression of pIGFBP-1 in the CVF and the onset of preterm birth. Eight patients showed positive results amongst the symptomatic patients and as predicted, within 14 days, 6 of those patients did go into preterm labour.

Conclusion: Appropriate scanning for pregnant women can be of excellent value as it has the potential to reduce the number of premature babies being born; this would also mean that the health complications associated with premature births can be prevented.

Hemobilia is an extremely rare cause of upper gastrointestinal bleeding. It often has intermittent manifestation, which may lead to significant diagnostic delay. In 65% of the cases, the causes are iatrogenic, in 7% the cause is malignancy, in 5% - gallstones, in 8% it is inflammation (cholecystitis, parasites, reflux cholangitis), vascular abnormality is the cause in 7% (most commonly pseudoaneurysm of the hepatic artery), and pancreatic pseudocyst causes hemobilia in 1%. In almost all cases, the bleeding originates from intrahepatic or extrahepatic bile ducts, and rarely from the pancreas.

PUBMED search with keywords “hemobilia” and “arteriobiliary fistula” found a total of 44 papers. No case with intrapancreatic arterio-biliary fistula was found. To the best of our knowledge, we present a unique case of delayed life-threatening hemobilia caused by intrapancreatic arterio-biliary fistula. It was diagnosed at the fourth admission and managed successfully by emergency Traverso-Longmire pancreatoduodenal resection. We briefly discuss the keys to a timely diagnosis and the cornerstones of the treatment.

The timely diagnosis of hemobilia depends on a high index of suspicion and careful interpretation of the symptoms. Hemodynamic stability has a crucial role in the decision-making process. Angioembolization is the cornerstone of the treatment, whereas surgery is reserved only for cases with an unstable hemodynamic or unsuccessful embolization. Surgical approach depends on the bleeding site. Although an emergency pancreatic head resection is a procedure of last resort, it can be life-saving in cases with intractable bleeding due to intrapancreatic arteriobiliary fistula.

Calcinosis (hydroxyapatite and calcium phosphate crystal deposition) within the extracellular matrix of the dermis and subcutaneous tissue is a frequent manifestation of adult and pediatric systemic autoimmune rheumatic diseases, specifically systemic sclerosis, dermatomyositis, mixed connective tissue disease, and systemic lupus erythematosus. In this article, we review classification of calcinosis, highlight mechanisms that may contribute to the pathogenesis of calcinosis, and summarize the evidence evaluating nonpharmacologic and pharmacologic interventions for the treatment of calcinosis.
Le désir de savoir fait penser. Le cas du petit Hans
Authors: Borges Anacleto Julia Maria , de Lajonquière Léandro
Published: May 2022

L’idée que la pensée est un dérivé du développement de l’intelligence comprise comme une capacité innée d’adaptation à l’environnement physique et/ou social de l’organisme humain est une idée hégémonique dans le domaine pédagogique. Elle conduit les professionnels intéressés aux transformations de la pensée chez l’enfant à se limiter à la vérification d’un programme évolutif considéré comme naturel et normal, à partir duquel toute réponse de l’enfant différente de ce qui est attendu sera considérée comme une déviation et donc l’indice d’un trouble psychobiologique. Afin de questionner cette idée, nous revisitons le cas clinique freudien du Petit Hans et sa relecture opérée par Lacan afin de mettre en évidence l’importance de l’angoisse de castration dans le penser. En ce sens, nous proposons de considérer les formulations des enfants comme le résultat d’un parcours signifiant, opérateur de la pensée, pris dans la dialectique entre demande d’amour et désir de savoir. L’accomplissement de ce parcours implique l’inscription inconsciente du signifiant du manque dans l’Autre grâce à laquelle l’impossibilité de savoir sur le désir pose le désir de savoir comme cause du penser.
Tjehenou , Tjemeh et les libyens : à la recherche d’une langue libyque dans les premières sources écrites de l’Ancienne Égypte
Authors: Panaite Elena
Published: May 2022

Les sources écrites égyptiennes transcrivent un certain nombre de vocables étrangers ou désignant des populations étrangères dont la filiation linguistique n’est pas toujours assurée. Tjehenou et Tjemeh, les deux premières appellations pour des peuples vivant à l’ouest de la vallée du Nil, posent encore des difficultés de compréhension. Du fait de leur position géographique, leur appartenance à un niveau ancien de la langue libyque a parfois été suggérée. À cela s’ajoutent d’autres toponymes et anthroponymes qui sont leur sont associés. La présente communication propose de faire un point de tous ces termes.
EU Lobbying in the “Age of Zoom”: How Was Environmental Policy Impacted?
Authors: Curreli Carolina
Published: May 2022

La pandémie à laquelle le monde est confronté a bouleversé notre société, obligeant tous les secteurs à concevoir de nouvelles approches et s’adapter à une vie en ligne. Dans le cadre d’une compétition sous-tendue par une vague potentielle de changements politiques, le secteur du lobbying environnemental a dû faire preuve de souplesse et s’ouvrir à la pratique de nouvelles méthodes. Le véritable intérêt de l’UE pour la politique environnementale s’est traduit par le « Green Deal » européen (Pacte vert pour l’Europe). Ce dossier a suscité le plus intense de lobbying au cours des premières vagues de la pandémie de COVID-19. Toutefois, l’urgence actuelle a généré de nouveaux défis, qui ont eu un impact sur l’orientation du lobbying, ainsi que sur la visibilité, les coalitions et les tactiques des organisations environnementales. Les résultats des entretiens menés pour cette analyse ont montré que la numérisation a déjà envahi notre société, de sorte que l’« ère du zoom » n’a pas entravé les activités de lobbying environnemental. À l’avenir, toutefois, le lobbying s’appuiera sur des stratégies hybrides, sans cesser de se concentrer sur les enjeux écologiques, désormais centraux pour l’UE.
Complex Systems, Fragility and Security: Challenges for the EU Governance and Its Global Partners in Climate Change and Digitalization
Authors: Lucatello Simone , Leconte Arnaud
Published: May 2022

Le modèle actuel de gouvernance mondiale se caractérise par l’interaction de plusieurs systèmes et variables non linéaires. Il en résulte un environnement complexe qui pose des défis importants à l’UE et aux autres acteurs politiques et économiques du Nord et du Sud. La fragilité, les menaces climatiques face aux menaces sécuritaires ainsi que la transformation numérique constituent un cadre mondial dans lequel l’UE et ses partenaires mondiaux doivent aller de l’avant. Dans cet article, nous analysons certains de ces systèmes de gouvernance complexes auxquels l’UE fait face. Nous soutenons qu’il devient nécessaire d’aller au-delà des approches réglementaires traditionnelles d’élaboration de règles, de conformité et de leur application ; il s’agirait surtout d’adopter de nouveaux cadres de gouvernance. Il s’agit notamment d’améliorer l’interaction entre la science et la politique, en favorisant et engageant des dialogues sur des décisions et des actions environnementales complexes, tels que l’interaction entre le changement climatique et la numérisation. Une collaboration plus efficace entre les différents secteurs, y compris le secteur privé, peut contribuer à optimiser les structures de gouvernance et à atteindre des résultats durables dans un monde aux systèmes complexes.
Refouler la défaite : le mythe de l’armée de l’air invaincue en 1940
Authors: d’Abzac-Epezy Claude
Published: May 2022

Le mythe selon lequel l’armée de l’air française aurait remporté en mai-juin 1940 davantage de victoires sur la Luftwaffe qu’elle n’a subi de pertes et qu’elle serait donc « invaincue » naît dès le mois de juillet 1940 dans le contexte de l’attaque anglaise sur Mers el-Kébir. Malgré les démentis, ce mythe fait l’objet de croyances tenaces, car il renforce une identité positive de l’armée de l’air et des pilotes de chasse. Cette étude propose de retracer comment le mythe a pris naissance et s’est imposé pour tenter ensuite de comprendre le contexte et les raisons de la falsification historique et enfin d’en analyser les conséquences, car nier l’échec, c’est aussi s’exposer à le reproduire.
Du charisme managérial à l’éclatement. Réagencement des rapports de domination en école d’ingénieurs
Authors: Le Lay Stéphane , Nusshold Patricio
Published: May 2022

À partir d’une enquête en psychodynamique du travail menée avec des employées administratives de la catégorie « ingénieurs, techniciens, administratifs » (ita) d’un service des réalisations industrielles d’une école d’ingénieurs, cet article interroge les transformations progressives d’une coopération fondée sur l’exercice d’une forme de management charismatique par le responsable du service. Les analyses montrent que, pendant plusieurs années, un fort engagement individuel dans les activités, en particulier de care, a permis le développement de la coopération et des résultats. Une modification de l’équilibre affectif et relationnel du collectif, suite à l’arrivée d’une nouvelle ita, a sapé l’autorité charismatique du directeur, entraînant un remaniement des rapports de coopération et des stratégies de défense des salariées.
Violence des échanges en milieu universitaire et déni des émotions
Authors: Jeantet Aurélie
Published: May 2022

L’article se fonde sur une recherche-action menée dans un département universitaire français, à la suite de plusieurs cas de souffrance aiguë. Les entretiens et observations auprès d’enseignants-chercheurs, administratifs et doctorants confirment une violence interpersonnelle et des atteintes à la santé, sur fond de restructurations institutionnelles permanentes et de précarisation des doctorants. La peur, omniprésente, empêche tant l’expression de la vulnérabilité individuelle que la constitution d’une résistance collective. À la place, on constate une stratégie défensive de déni des émotions qui explique la pérennité de cette situation délétère. Cette dernière parvient cependant à s’assouplir au fil de l’intervention, par l’écoute et par l’analyse sociologique et psychodynamique des trajectoires, des pratiques, des émotions, de l’organisation du travail et des rapports de pouvoir.
Pour un tournant écologique en psychosociologie
Authors: Faure David
Published: May 2022

Les psychosociologues n’ont pas encore suffisamment intégré la crise écologique dans leur interventions et interrogé ses enjeux dans leurs pratiques. L’article, qui prend la forme d’un essai pour ouvrir un débat, part de l’hypothèse que cette difficulté tient principalement à un ancrage dans le courant classique des sciences humaines et sociales dont l’anthropocentrisme est aujourd’hui interrogé ; d’autre part à mettre en évidence les ressources présentes pour effectuer ce tournant. La démarche proposée part de la grille de lecture de la complexité de la réalité sociale établie dès 1966 par Jacques Ardoino, en tant que référence pour de nombreux psychosociologues. Je propose d’ajouter deux dimensions ou instances : le corps et la Terre, pour étendre le cadre de référence des analyses psychosociologiques et inviter à renouveler les références de la discipline et ouvrir sa pratique aux enjeux actuels.
