Antilogie. Guerre(s) et crise(s) globales : sur leurs relations systémiques
Authors: Herrera Rémy 
Published: May 2021

Dans cet article, l’auteur interroge les liens complexes existant entre les guerres et les crises globales. Dans une première partie, il développe préalablement les notions de crise (sous-partie 1) et de guerre (sous-partie 2) en les resituant respectivement tant dans le courant néoclassique actuellement dominant en économie que dans les pensées hétérodoxes – l’accent étant plus particulièrement mis sur le marxisme. Dans une seconde partie, c’est la nature des relations entre guerres et crises globales qui est examinée d’un point de vue économique, sous les angles à la fois théorique et historique (sous-partie 1). Puis, les contradictions systémiques que de telles relations crises-guerres contribuent à accentuer sont analysées (sous-partie 2). L’attention du lecteur est finalement attirée sur les nouveaux risques sous-jacents, notamment ceux qui ont récemment surgi dans le cadre de la nouvelle « Guerre froide » opposant les États-Unis à la Chine, avec des illustrations proposées autour de réflexions sur la guerre commerciale sino-étasunienne, ainsi que sur la guerre des monnaies dollar-yuan (sous-partie 3).
Le convivialisme est-il un associationnisme ?
Authors: Sue Roger 
Published: May 2021

Le convivialisme est-il un associationnisme ? Sa parenté est en tout cas évidente par ses multiples références aux acteurs associatifs et mouvements citoyens. Si tel est le cas, ne devrait-il pas plus clairement revendiquer cette filiation qui remonte aux premiers socialistes et à la révolution de 1848. S'inscrire dans cette histoire du lien social d'association avec ses implications économiques et politiques lui donnerait sans doute une cohérence théorique et conceptuelle plus forte, tout en lui permettant d'en revendiquer la nécessaire actualisation.

Published: May 2021

O Comitê Paralímpico Internacional, órgãos reguladores do esporte paraolímpico, bem como alguns representantes de cidades/países sedes dos Jogos Paralímpicos, alegam que estes Jogos se constituem em uma importante plataforma para modificar as percepções da sociedade em relação às capacidades das pessoas com deficiência (PCD). Tendo em vista estas alegações, desenvolvemos uma pesquisa com o objetivo de verificar se indivíduos que tiveram contato com os Jogos Paralímpicos mudaram a sua percepção em relação às capacidades das PCD. O estudo foi de cunho qualitativo e exploratório. A coleta de dados foi baseada em entrevistas semiestruturadas desenvolvidas entre abril e julho de 2018. Entrevistamos 50 acadêmicos de diferentes cursos da Universidade Federal do Paraná (UFPR). Realizamos uma análise temática dos dados e utilizamos a Teoria de Contato entre Grupos (TCEG) como base para a discussão. Os resultados deste trabalho reafirmam a tese da TCEG que postula que tanto o contato direto quanto o indireto com grupos distintos pode servir como uma ferramenta para a diminuição de preconceitos.

COVID-19 is an emerging viral disease affecting more than 200 countries worldwide and it present with varied clinical profile throughout the world. Without effective drugs to cure COVID-19, early identification and control of risk factors are important measures to combat COVID-19. This study was conducted to determine the clinical profile and risk factors associated with mortality among COVID-19 patients in a tertiary care hospital in South India. This record-based longitudinal study was conducted by reviewing the case records of COVID-19 patients admitted for treatment from June 2020 to September 2020 in a tertiary care centre in South India. The clinical details, discharge/death details, were collected and entered in MS Excel. Potential risk factors for COVID-19 mortality were analysed using univariate binomial logistic regression, generalized linear models (GLM) with Poisson distribution. Survival curves were made using the Kaplan-Meier method. Log-rank test was used to test the equality of survivor functions between the groups. Out of 854 COVID-19 patients, 56.6% were men and the mean (standard deviation) age was 45.3(17.2) years. The median survival time was significantly lesser in male COVID-19 patients (16 days) as compared to female patients (20 days). Increasing age, male gender, patients presenting with symptoms of fever, cough, breathlessness, smoking, alcohol consumption, comorbidities were significantly associated with mortality among COVID-19 patients. Patients with older age, male gender, breathlessness, fever, cough, smoking and alcohol and comorbidities need careful observation and early intervention. Public health campaigns aimed at reducing the prevalence of risk factors like diabetes, hypertension, smoking and alcohol use are also needed.
Every symplectic manifold is a (linear) coadjoint orbit
Authors: Donato Paul , Iglesias-Zemmour Patrick 
Published: May 2021

AbstractWe prove that every symplectic manifold is a coadjoint orbit of the group of automorphisms of its integration bundle, acting linearly on its space of momenta, for any group of periods of the symplectic form. This result generalizes the Kirilov–Kostant–Souriau theorem when the symplectic manifold is homogeneous under the action of a Lie group and the symplectic form is integral.
Stress and obligativity of police officers
Authors: Călin Mariana Floricica , Rus Mihaela , Sandu Mihaela Luminita 
Published: May 2021

In the present study, I examined the differences between criminal police officers and border police officers. The study shows if there are any semnificative differences of stress and mentality for the two types of policemen. 2 tests were applied on 60 participants, 30 of each category. One test was for measuring stress and the other one for observing the mentality of the employees. The study has 2 hypotheses: the presumtion that there are semnificative differences of stress between the two types of officers and the presumtion that there are semnificative differences between levels of obligativity for the two types of officers. The hypotheses were confirmed.
Student Teachers Perceptions and Experiences on School Practice and Competence Development at Makerere University-Uganda
Authors: Bwiruka Jane , Maani John , Ssetumba John 
Published: May 2021

Purpose: The study was carried out to explore the student teachers’ perceptions and experiences on school practice in terms of competence development.
Methodology: Phenomenology as a design was adopted using unstructured interviews and documents review to collect data from twelve purposively selected third year student teachers as participants. Data was analyzed using the framework analysis.
Findings: School practice was clearly understood by participants as a learning experience that involves putting theory into practice with the help from supervisors and senior teachers. However, it was conducted along the curriculum requirements as an assessment/examination by the university supervisors. Consequently, some challenges were faced. These included, difficulties in applying all the various methods taught by different lecturers, lack of professionalism, little feedback/conferencing with supervisors, hurried reports, limited mentorship and supervisory aspects in school practice host schools and limited materials to use among others.
Unique Contribution to Theory, Practice and Policy: The teacher preparation institutions in Uganda Makerere inclusive need to improve the general methods course to all students to cater for issues in lesson preparation, presentation, classroom management, assessment and evaluation. An interdependent relationship between the University and the SP host schools is required to promote a working relationship between the supervisors and host teachers for mentoring and supervisory aspects to student teachers. Makerere University and other teacher preparation institutions need constant professional development courses to promote professionalism among supervisors to address issues like lack of feedback/conferencing and poor supervisor-student relationships among others.
The diurnal Energy Balance Model (dEBM): a convenient surface mass balance solution for ice sheets in Earth system modeling
Authors: Krebs-Kanzow Uta , Gierz Paul , Rodehacke Christian B. , Xu Shan , Yang Hu , Lohmann Gerrit 
Published: May 2021

Abstract. The surface mass balance scheme dEBM (diurnal Energy Balance Model) provides a novel interface between the atmosphere and land ice for Earth system modeling, which is based on the energy balance of glaciated surfaces. In contrast to empirical schemes, dEBM accounts for changes in the Earth’s orbit and atmospheric composition. The scheme only requires monthly atmospheric forcing (precipitation, temperature, shortwave and longwave radiation, and cloud cover). It is also computationally inexpensive, which makes it particularly suitable to investigate the ice sheets' response to long-term climate change.
After calibration and validation, we analyze the surface mass balance of the Greenland Ice Sheet (GrIS) based on climate simulations representing two warm climate states: a simulation of the mid-Holocene (approximately 6000 years before present) and a climate projection based on an extreme emission scenario which extends to the year 2100.
The former period features an intensified summer insolation while the 21st century is characterized by reduced outgoing longwave radiation. Specifically, we investigate whether the temperature–melt relationship, as used in empirical temperature-index methods, remains stable under changing insolation and atmospheric composition. Our results indicate that the temperature–melt relation is sensitive to changes in insolation on orbital timescales but remains mostly invariant under the projected warming climate of the 21st century.

PLANT-DERIVED CHEMOTHERAPEUTICS DRUGS FOR CANCER CHEMOTHERAPY
Authors: Dragoi Alexandra , Alexandru Oana 
Published: May 2021

Cancer chemotherapeutic drugs acts in different manner to kill malignant cells. Most of the anticancer drugs available in clinical practice to treat cancer patients, are natural products including whole plant extract, crude plant extracts, isolated constituents, plant –based drug formulations etc. These natural compounds have been a basis for the development of several drugs against cancer. Agents such as topotecan, taxol, vinca alkaloids (vincristine, vinblastine, vinorelbine and vindesine), are important anticancer agents in widespread clinical use. Other agents, such as combretastatin, flavopiridol, betulinic acid were shown to have anti-tumor effects in both in vitro and in vivo experiments.
In this review, we aim to make a brief description of classical plant-derived chemotherapeutics drugs and also to highlight the importance of these natural compounds in the development of new potential drugs in cancer treatment.

Person-centred enforcement of social security laws An action research study on the significance of motivational postures at a welfare office
In this article, we discuss a ‘person-centred’ view on the enforcement of social security laws. This is a new vision on enforcement whereby welfare workers can ‘differentiate’ in order to create more room for ‘customization’ with an eye for ‘the human dimension’ and an ‘appropriate’ enforcement style. Despite the unanimity about the desirability of this approach, most of the practical details are still unclear. Our central question is therefore: How may a person-centred approach of the enforcement of social security laws be implemented in practice? Based on an action research study, in which we closely collaborated with welfare workers and benefit recipients at a Dutch welfare office, we attempt to answer this question. We first discuss a number of central concepts from the enforcement literature and consider the concept of ‘motivational postures’. For this study, we developed a prototype of a new electronic analytical tool (which can be used to support enforcement) and then applied this tool in a small pilot study. In the article we describe our findings and discuss the experiences of benefit recipients and welfare workers with the analytical tool. We conclude that this tool appears to offer a good basis for the further development of the person-centred enforcement of social security laws.

Dispute settlement among the Nigerian Igbo in Antwerp
This is a case study in ‘new legal pluralism’ which is interested in the operation of plural legal orders in countries of the global North. It considers the way in which the Nigerian Igbo living in Antwerp, Belgium settle their disputes. It first presents the Antwerp Igbo’s organisation in a Union possessing a constitution with precise legal stipulations. It then finds that the Igbo take the law with them from their home region into a diasporic community. Next it looks into the concrete organisation of dispute settlement and presents five cases as exemplars. It then discusses the advantages and drawbacks of applying Igbo law and justice, the issue of women’s rights, and the plurality and flexibility of the system. The conclusion underscores the fact that legal pluralism is a universal empirical reality.

Published: May 2021

<p><strong>Objective</strong>. The aim of this report is to highlight the importance of close observation and follow-up in children who present with an acutely irritable hip. This is because hip pain is a symptom of not only benign but also severe conditions. Thus, at the time of the initial presentation, hip pain can be misdiagnosed. This report serves as an example for a wide range of doctors such as orthopaedic surgeons, paediatricians, emergency room physicians or primary care physicians, because these are the first-line doctors who treat patients with a painful hip. <strong>Case report</strong>. We herein present a three-year-old child who was admitted to our hospital with pain in the right leg and initially diagnosed with<br />transient synovitis of the hip. An additional examination two days later, after severe deterioration of the clinical picture, revealed that our patient was actually suffering from Guillain-Barré syndrome. Failure to diagnose Guillain-Barré syndrome and initiating prompt treatment is potentially life-threatening. <strong>Conclusion</strong>. Clinicians should be aware that hip pain could be the presenting complaint of Guillain-Barré syndrome, a syndrome that has many clinical features. Even when all the clinical and laboratory findings indicate a benign condition, Guillain-Barré syndrome should still be considered. Therefore, close observation and follow-up in children who present with an acutely irritable hip is highly recommended. In this way, the potentially catastrophic consequences of more severe conditions can be avoided.</p>
Adverse drug reactions of non-opioid and opioid analgesics reported to Croatian national authority from 2007 to 2014
Authors: Sunara Petra , Krnic Darko , Puljak Livia 
Published: May 2021

<p><strong>Objective. </strong>Adverse drug reactions (ADRs) are commonly observed in the health services because of system weaknesses and individual errors. Analgesics are widely used and it can be expected that with the increased use one can expect increased number of ADRs of analgesics. The aim of this study was to analyze ADRs of non-opioid and opioid analgesics reported to the Croatian Agency for Medicinal Products and Medical Devices (HALMED) from 2007 to 2014. <strong>Methods. </strong>HALMED provided data on generic drug name, year of the ADR re- port, type of report, institution, reporting person, patient’s age, sex and ADR type. <strong>R</strong><strong>esults. </strong>In the analyzed period 796 ADRs of analgesics were reported, of which 367 (46%) were serious ADRs. Number of ADR reports was continuously increasing during the analyzed period. There were 20 analgesics that had ≥5 reports, making 597 (75%) of all ADR reports for analgesics. The most common adverse reaction re- ports of those 20 analgesics referred to individual drugs (n=16; 80%). Most of the ADR reports were filed by physicians (n=257; 43%), fol- lowed by pharmacists (n=252; 42%). Most side effects (n=572; 96%) were reported spontaneously through appropriate forms by patients or health professionals. ADRs were most commonly reported in wom- en (n=352; 59%) and most of them have occurred in adults (n=354; 59%). The most common ADRs of opioid and non-opioid analgesics have been reported on the skin and mucous membranes. Most serious ADRs were result of action of opioid analgesics. <strong>C</strong><strong>onclusion. </strong>Num- ber of ADR reports in Croatia is continuously increasing and a consid- erable number of them refers to serious ADRs. To keep better track of medications and ADRs it is necessary to educate and encourage health professionals and patients in reporting side effects</p>

Published: May 2021

Context.—
The original guideline, “Validating Whole Slide Imaging for Diagnostic Purposes in Pathology,” was published in 2013 and included 12 guideline statements. The College of American Pathologists convened an expert panel to update the guideline following standards established by the National Academies of Medicine for developing trustworthy clinical practice guidelines.

Objective.—
To assess evidence published since the release of the original guideline and provide updated recommendations for validating whole slide imaging (WSI) systems used for diagnostic purposes.

Design.—
An expert panel performed a systematic review of the literature. Frozen sections, anatomic pathology specimens (biopsies, curettings, and resections), and hematopathology cases were included. Cytology cases were excluded. Using the Grading of Recommendations Assessment, Development, and Evaluation approach, the panel reassessed and updated the original guideline recommendations.

Results.—
Three strong recommendations and 9 good practice statements are offered to assist laboratories with validating WSI digital pathology systems.

Conclusions.—
Systematic review of literature following release of the 2013 guideline reaffirms the use of a validation set of at least 60 cases, establishing intraobserver diagnostic concordance between WSI and glass slides and the use of a 2-week washout period between modalities. Although all discordances between WSI and glass slide diagnoses discovered during validation need to be reconciled, laboratories should be particularly concerned if their overall WSI–glass slide concordance is less than 95%.

Parametric Design and Optimization of Sailing Yachts
Authors: Harries Stefan , Abt Claus 
Published: May 2021

A new and flexible method for the geometric modeling of ship hull forms is presented. The underlying methodology is the parametric design of B-spline curves and surfaces. Important form parameters like displacement, center of buoyancy, waterplane area, center of flotation etc. are utilized as high-level descriptors of the intended shapes. Instead of interactively manipulating B-spline vertices, the generation process is viewed as a constrained optimization problem where fairness measures are applied as objective functions, vertices are treated as design variables and form parameters are preserved as equality constraints - making the approach a novelty in B­spline modeling.
The new design methodology is discussed and mathematical principles are outlined. Examples are given to demonstrate the applicability of the parametric approach. They include the design of a 33ft IMS yacht with focus on the bare hull without rudder and keel.
Use of CFD Techniques in the Preliminary Design of Upwind Sails
Authors: Couser Patrick , Deane Norm 
Published: May 2021

The results of the 1997 World Titles, held in Kingston, Canada, highlighted that there was considerable scope for improving the upwind performance of the international Mirror Class by making small adjustments, within the tolerances allowed by the class rule, to the sails and underwater foils. This paper describes some aspects of the Australian research and development programme in preparation for the 1999 World Titles to be held in South Africa in April.
Computational methods, based on the vortex lattice method, have been used to provide direction and guidance for the on-the-water testing and trialing programme. The use of these theoretical tools has enabled a far wider range of sail, dagger board and rudder parameters to be investigated than would be possible using purely on-the-water testing.
The usefulness of well-understood computational and numerical methods in sail and foil design has been demonstrated; it has also been shown that these tools are within the reach of relatively small budget research and development programmes. The proof of the pudding may be at the 1999 International Mirror Class World Titles ... (watch this space)
