المنظومة العسكرية في أطروحات مؤرخي الغرب الإسلامي
Authors: بولعراس خميسي
Published: March 2023

ساهم بعض مؤرخي الغرب الإسلامي في إثراء المنظومة العسكرية الإسلامية بأطروحاتهم وآرائهم ، والتي استندوا من خلالها على مرجعيات مختلفة وتجاربهم الخاصة مع الجيوش فكانوا أكثر تفتح على الأخر عسكريا وتكتيكيا في الحروب ولم يكونوا منغلقي الفكر فقدموا بذالك منظومة في فن الحرب من منطلقات إسلامية وسبل تحقيقها ميدانيا ولعل المرادي الحضرمي مؤرخ الدولة المرابطية و أبوبكر الصيرفي وأبو حموا موسى الزياني الثاني، هي نماذج أحدثت ثورة في القتال الحربي في العصر الوسيط، فما مدى حضور هذه الأطروحات في كتاباتهم؟ إذا أن الهدف من هذا الموضوع هو تبيان صورة أخرى للنخب المؤرخة، وهي صورة المنظر والمفكر العسكري، وليس ناقل للأحداث والتواريخ فقط ولعل أهم ما توصلنا إليه هو أن تاريخ العصر الوسيط تاريخ تميز بإنتشار الحروب والمعارك المستمرة، كان عاملا وحافزا لهؤلاء المؤرخين ليكتبوا وينظروا في فن الحرب، ثم أن هذه النخب كانت نخبا موسوعية أهلتها معارفها المختلفة إلى الإجتهاد في إنتاج المعرفة العسكرية التي أدت إلى إعجاب الأخر بها، كما أن سر نجاحها هو اعتمادها على العقيدة الإسلامية كمنطلق لمواجهة الأخر

دفعت التحولات الحديثة التي صاحبت العولمة إلى إحداث تغييرات في الكثير من المفاهيم، باعتبارها تتضمن انكماش العالم وإلغاء الحدود الجغرافية وربط الاقتصادات والثقافات والمجتمعات والأفراد بروابط تتخطى الدول وتتجاوز سيطرتها التقليدية على مجالها الوطني والمحلي، كما قلصت من سيادتها وحرية تصرفها في شؤونها الخارجية، وهو ما يتنافى مع مفاهيم الدولة القومية التي تحرص على عدم التفريط بسياستها ضمن نطاقها الجغرافي ومجالها الوطني بعيدا عن التدخلات الخارجية. هذه المفاهيم التي ترتبط أشد الارتباط بمفهوم السيادة وممارسة الدولة لصلاحياتها وسلطاتها على شعبها وأرضها وثرواتها الطبيعية. سنحاول من خلال هذه الدراسة التعرض لمختلف التحولات التي ترافقت مع ظاهرة العولمة في مرحلة ما بعد الحرب الباردة، بغرض الإجابة على الإشكالية التالية: كيف تأثرّ كل من الشأن الداخلي والخارجي للدولة الوطنية بالتجليات العميقة والمكثفة لظاهرة العولمة في عالم ما بعد الحرب الباردة
مبدأ الوقاية من العقوبة في التشريع الإسلامي - الحدود أُنموذجا-

ملخص البحث من محاسن الشريعة الإسلامية أنّ أحكامها قائمة على أصل تكريم الله لبني آدم، وحفظ ما يضمن جريان حياتهم على استقامة، وما من شيء فيه صلاح إلاّ وكان لها قصب السبق في تشريعه، ومن ذلك مبدأ الوقاية قبل العلاج، فالنظام الإسلامي احتاط لوقوع ما يمكن أن يؤدي إلى إحداث ضرر قبل السعي لرفع الضرر وعلاجه. عند التأمل في التشريع الجنائي وبخاصة الحدود، تبرز لنا معالم نظرية مكتملة ومنهج وقائيّ محكم، يقوم على الوقاية من العقوبة، ليبرهن أنّ العقاب ليس الغاية، وإنّما هو آخر الأمر، كما أنّ الكيّ آخر الدواء. جاء في هذا العرض الموجز تجلية هذه النظرية، وبيان معالمها قبل الوقوع في الجرم الموجب للحد وبعده، وذلك إسهاما في الذبّ عن هذا الجزء من التشريع الذي كان ولايزال محل نقد وتشكيك.

Abstract

The following researching paper seeks to highlight the most important speeches that Ben Nabi had used in establishing his civilizational project. There is no doubt that Ben Nabi’s social equation is based on identifying the civilization supports, then integrating them in a unison to put into effect the role of soil and recognizing the man’s value and respecting time. To accomplish this, Ben Nabi used the comparative approach to prove that the civilizational renaissance requirements are phenomenal and incarnate as long as nations have responded to the idea of civilization.
Production of Acetic Acid and Whey Protein from Cheese Whey in a Hybrid Reactor under Response Surface Optimized Conditions
Authors: Nayak Jayato , Chakrabortty Sankha
Published: March 2023

Experimental investigations were carried out in a membrane-integrated hybrid bio-reactor system for direct and continuous production of acetic acid and whey protein from waste cheese whey under response surface optimized conditions. In this novel scheme of fermentative production, using Acetobactor aceti, the major operating parameters such as temperature, concentrations of yeast extract, and glucose were optimized. Under the set of optimum operating conditions (temperature of 300 °C, pH of 6.0, yeast extract concentration of 15 g/L and glucose concentration of 44 g/ L), more than 95% pure acetic acid was produced with a concentration of 84.1 g/L, yield of 97.4% and productivity of 7.2 g/(L· h). Simultaneous production of whey protein powder makes the process more economically viable. Findings indicate that acetic acid could be produced directly and continuously from waste cheese whey with high productivity, yield and purity under response surface optimized conditions, in a simple, flexible, energy-saving and environmentally benign membrane-integrated hybrid reactor system.

Published: March 2023

This study examined the relationship between job satisfaction and job contentment in the context of Nigerian banks using selected banks in the Southwest of Nigeria as the unit of analysis. A structured questionnaire was administered to elicit relevant information from 123 respondents using both stratified and simple random techniques. The study identified six (6) components of job satisfaction that drive job contentment such as job security, salary, human relations, promotion, organizational benefits, and job characteristics, and also established a positive relationship between job satisfaction components and job contentment. It was found that salary, job security, and organizational benefits drive job contentment more among employees in the banking industry but job security was considered to be the most potent drive of job contentment among all while the relationship among all the job satisfaction components with job contentment was a moderate relationship except human relations that has a weak relationship at 0.05 level of significance. The regression result showed that all the components of job satisfaction have an effect on employee job contentment and it was concluded that the six components of job satisfaction should be entrenched in the organizational retention strategies to guarantee job contentment among employees in the banking industry. Thus, recommended that the implementation of the organizational policies towards the components of job satisfaction should be fair, just, and free of any form of sentiments that can affect their perception and feelings about these components.

As a result of the research, a model is constructed that relates, both directly and indirectly, the characteristics of the academic body, the development of critical thinking in students and educational outcomes in initial teacher training.
Effects of internally directed cognition on smooth pursuit eye movements: A systematic examination of perceptual decoupling
Authors: Korda Živa , Walcher Sonja , Körner Christof , Benedek Mathias
Published: March 2023

Eye behavior differs between internally and externally directed cognition and thus is indicative of an internal versus external attention focus. Recent work implicated perceptual decoupling (i.e., eye behavior becoming less determined by the sensory environment) as one of the key mechanisms involved in these attention-related eye movement differences. However, it is not yet understood how perceptual decoupling depends on the characteristics of the internal task. Therefore, we systematically examined effects of varying internal task demands on smooth pursuit eye movements. Specifically, we evaluated effects of the internal workload (control vs. low vs. high) and of internal task (arithmetic vs. visuospatial). The results of multilevel modelling showed that effects of perceptual decoupling were stronger for higher workload, and more pronounced for the visuospatial modality. Effects also followed a characteristic time-course relative to internal operations. The findings provide further support of the perceptual decoupling mechanism by showing that it is sensitive to the degree of interference between external and internal information.

How the ‘Lejabys’ Came into Being: Artists and Workers in Struggle. A Spatio-Temporal Odyssey between ‘Mobilising’ and ‘Organising’
Authors: Schmidt Géraldine , Mourey Damien , Bobadilla Natalia
Published: March 2023

Art and other creative approaches can be a resource or a mobilising strategy for activists and artists. Little work has been done, however, on what happens in the interactions between artists and activists in the daily life of a conflict. We suggest that social mobilisations may be seen as organising processes as well as mobilising actions, and we analyse how creative and artistic approaches may contribute to this organising/mobilising reciprocal relationship. Based on an analysis of the conflict that accompanied the announcement of the Lejaby plant closure in Yssingeaux in 2012, which inspired several artists, we show that these approaches, by their capacity to grasp sensitive dimensions, favour spatio-temporal episodes that structure the struggle: some constitute protected spaces, which can correspond to an intimate reflexive time or to a collective moment of synchronisation of subjective temporalities; others correspond to hybridised spaces, which can be sometimes empowering and sometimes theatrical. We thus contribute both to the field of social movement analysis and to the role of art and creativity in the organisation and mobilisation within these movements; we also contribute to a relational reading of the spatial and temporal dimensions of organisation and collective action, in the tradition of Lefebvre and Massey.
‘Not Too Good to be True’: A Proposal to Further Benefit from Emergence in Management Research
Authors: Adrot Anouck
Published: March 2023

Emergence is inherent to organizational life and design. Throughout the 20th and 21st centuries, emergence has been appraised as a conceptual avenue that surpassed the limitations of traditional thinking and epistemology. In this essay, I suggest that, despite its relevance and popularity among management scholars, emergence has remained underused. I rely on Kuhn’s view (1962) to better understand the reasons for this paradox and propose some practical avenues to improve our understanding and use of the concept. This essay has three objectives: (1) to demonstrate that emergence is relevant to better understanding organizations; (2) to explain why emergence remains underused in management and organization theory (MOT); and (3) to propose practical guidelines to further rely on the concept of emergence.

Timor-Leste as a new country has various efforts to advance the country itself, one of which is the achievement is to build several ports in three locations, because for the time being it still mandates one port located in the center of Dili city, namely; "Porto Dili", (port of Dili). Porto Dili port has 2 docks, passenger docks and container docks, facilities at Porto Dili port are inadequate such as the absence of counters for passenger tickets, waiting rooms, passenger toilets and one of the docks has a dual function, namely the loading and unloading of containers and as a passenger dock, this research is expected to realize good service quality in accordance with the needs and desires of its customers which leads to customer satisfaction. This study uses the Costumer Satisfaction Index (CSI) method The satisfactory CSI value is 80% while based on the results of research conducted in porto dili passenger terminal get a CSI value is 26%, this shows if the service on sea public transportation in porto dili port is not good and has not satisfied passengers.
Revealing the Galaxy–Halo Connection through Machine Learning

Published: March 2023

Understanding the connections between galaxy stellar mass, star formation rate, and dark matter halo mass represents a key goal of the theory of galaxy formation. Cosmological simulations that include hydrodynamics, physical treatments of star formation, feedback from supernovae, and the radiative transfer of ionizing photons can capture the processes relevant for establishing these connections. The complexity of these physics can prove difficult to disentangle and obfuscate how mass-dependent trends in the galaxy population originate. Here, we train a machine-learning method called Explainable Boosting Machines (EBMs) to infer how the stellar mass and star formation rate of nearly 6 million galaxies simulated by the Cosmic Reionization on Computers project depend on the physical properties of halo mass, the peak circular velocity of the galaxy during its formation history v
peak, cosmic environment, and redshift. The resulting EBM models reveal the relative importance of these properties in setting galaxy stellar mass and star formation rate, with v
peak providing the most dominant contribution. Environmental properties provide substantial improvements for modeling the stellar mass and star formation rate in only ≲10% of the simulated galaxies. We also provide alternative formulations of EBM models that enable low-resolution simulations, which cannot track the interior structure of dark matter halos, to predict the stellar mass and star formation rate of galaxies computed by high-resolution simulations with detailed baryonic physics.
RETRACTED: Forecasting Solar Cycle 25 Using an Optimized Long Short-term Memory Mode Based on F10.7 and Sunspot Area Data
Authors: Zhu Hongbing , Zhu Wenwei , Chen Haoze , He Mu
Published: March 2023

In this paper, an optimized long short-term memory model is proposed to deal with the smoothed monthly F
10.7 and nonsmoothed monthly sunspot area (SSA) data, aiming to forecast the peak amplitude of both solar activities and the occurring time for Solar Cycle 25 (SC-25), as well as to obtain the maximum amplitude of sunspot number (SSN) and the reaching time according to the relationships between them. The “reforecast” process in the model uses the latest forecast results obtained from the previous forecast as the input for the next forecasting calculation. The forecasting errors between the forecast and observed peak amplitude of F
10.7 for SC-23 and SC-24 are 2.87% and 1.09%, respectively. The results of this evaluation indicator of SSA for SC-21 to SC-24 were 8.85%, 4.49%, 2.88%, and 4.57%, respectively, and the errors for the occurring time were all within 6 months. The forecast peak amplitude of F
10.7 and SSA for SC-25 is 156.3 and 2562.5 respectively, and the maximum values of SSN are calculated as 147.9 and 213 based on F
10.7 and SSA respectively, which implies that SC-25 will be stronger than SC-24, and that SC-25 will reach its peak at the beginning of 2025.

Published: March 2023

O- and B-type (OB-type) pulsating stars are important objects for studying the structure and evolution of massive stars through asteroseismology. A large amount of data from various sky surveys provides an unprecedented opportunity to search for and study this kind of variable star. We identify 155 OB-type pulsating stars or candidates, including 38 Oe/Be stars or candidates, from the data observed by TESS, LAMOST, and Gaia, which are almost new. Among the 155 objects, 87 samples are identified as slowly pulsating B (SPB) stars including 37 objects with pure low-frequency and 50 objects with both low- and high-frequency pulsation, and 14 samples are identified as β Cephei pulsating variable (BCEP) stars with both low- and high-frequency pulsation. An H-R diagram shows that these SPB and BCEP stars are mainly located in their instability regions and in the evolutionary stage of the main sequence with mass ranges of 2.5–20 M
⊙ and 7–20 M
⊙, respectively. Two special objects show Fourier spectra similar to BCEP stars but with different positions in H-R, period–temperature (P-T), and period–luminosity (P-L) diagrams. Meanwhile, 52 other targets are identified as candidates of OB-type pulsating stars. We also derive the preliminary results of the P-L relation for SPB and BCEP stars, respectively. This work also indicates that in addition to the H-R diagram, the P-T and P-L diagrams are also very useful for the classification of SPB and BCEP stars. Further detailed analysis of these objects can dramatically increase our understanding of the theories of evolution and structure for massive OB-type pulsating stars.
Keck Integral-field Spectroscopy of M87 Reveals an Intrinsically Triaxial Galaxy and a Revised Black Hole Mass
Authors: Liepold Emily R. , Ma Chung-Pei , Walsh Jonelle L.
Published: March 2023

The three-dimensional intrinsic shape of a galaxy and the mass of the central supermassive black hole provide key insight into the galaxy’s growth history over cosmic time. Standard assumptions of a spherical or axisymmetric shape can be simplistic and can bias the black hole mass inferred from the motions of stars within a galaxy. Here, we present spatially resolved stellar kinematics of M87 over a two-dimensional 250″ × 300″ contiguous field covering a radial range of 50 pc–12 kpc from integral-field spectroscopic observations at the Keck II Telescope. From about 5 kpc and outward, we detect a prominent 25 km s−1 rotational pattern, in which the kinematic axis (connecting the maximal receding and approaching velocities) is 40° misaligned with the photometric major axis of M87. The rotational amplitude and misalignment angle both decrease in the inner 5 kpc. Such misaligned and twisted velocity fields are a hallmark of triaxiality, indicating that M87 is not an axisymmetrically shaped galaxy. Triaxial Schwarzschild orbit modeling with more than 4000 observational constraints enabled us to determine simultaneously the shape and mass parameters. The models incorporate a radially declining profile for the stellar mass-to-light ratio suggested by stellar population studies. We find that M87 is strongly triaxial, with ratios of p = 0.845 for the middle-to-long principal axes and q = 0.722 for the short-to-long principal axes, and determine the black hole mass to be

Phylogeny and taxonomy of the Risa genus-group (Diptera: Ephydridae), with description of a new genus from Australia
Authors: Mathis Wayne N. , Zatwarnicki Tadeusz
Published: March 2023

The systematic and somewhat controversial history of Risa Becker is presented, and its relationship with Diasemocera Bezzi (tribe Psilopini, Ephydridae) is documented by morphological evidence and an association with host plants in the family Amaranthaceae. The tribe Risini Papp (as Risidae) is synonymized with Psilopini Cresson. Notorisa gen. nov., from Australia, is described (type species: Notorisa mcalpinei sp. nov.; Australia. Victoria: Big Desert National Park, near Lake Hindmarsh; 36°03.7'S 141°54.8'E). Achaetorisa Papp is retained as a subgenus within Risa and includes five species, including two new combinations: Risa brevicornis (Papp) comb. nov., Risa salsolae (Mathis & Zatwarnicki) comb. nov., and two new species: R. brevirostris sp. nov. (Israel. Ẕomet Zohar; 31°08.5'N 35°21.6'E) and R. nettae sp. nov. (Israel. Ẕomet Zohar; 31°08.5'N 35°21.6'E). A fourth new species is described in the subgenus Risa: R. (Risa) kotrbae sp. nov.

Changes in the flora of Lobbia Alta, a peak of the Adamello-Presanella Alps (Trento, Italy) between 1935 and 2021
Authors: Prosser Filippo , Bertolli Alessio , Tomasi Giulia
Published: March 2023

Global warming is causing an enrichment of summit flora worldwide. This article presents the case of a peak in the southeastern Alps (Lobbia Alta, 3,196 m a.s.l., Adamello, Trento, Italy), for which a complete list of tracheophytes dating back to 1935 was available. As this peak is well delimited by glaciers and vertical cliffs, it has been possible to faithfully repeat this floristic inventory. We made three surveys, in 1991, 2006 and 2021, exploring the whole area. It resulted that in 86 years the species present on this peak have tripled, increasing from 17 to 51, with an acceleration in recent years. The biological forms have increased from two to six. The average temperature and the nutritional indexes according to Ellenberg have increased as well. We found that as many as six species reach their elevation record in the Alps on the Lobbia Alta, suggesting that this area is particularly prone to species ascension. Particularly interesting is the discovery of a 35 cm-tall specimen of Larix decidua at 3,130 m a.s.l., which seems to be the elevational record of the species.

L’attachement : diversité et diversification, un modèle d’éthologie humaine
Authors: Brunod Regis , Cook-Darzens Solange
Published: March 2023

Même s’il en est en quelque sorte le prolongement dans le monde aérien, l’attachement entre un bébé et sa mère n’est pas, comme auparavant le cordon ombilical, un lien monolithique. Pourtant, sauf accident, l’attachement s’installe bien pendant la période néonatale dans un lien vital mère-enfant quasi exclusif, lien reposant, entre autres, sur un substrat biologique hormonal clairement identifié. Cependant cela n’a qu’un temps et pour le bon développement de l’enfant ainsi que pour la vie de la mère il est nécessaire que ce lien se diversifie et se partage ensuite avec d’autres personnes au sein d’un groupe social, tout d’abord une famille ou son extension. C’est ce que nous appelons la diversification de l’attachement. Mais la manière et le tempo de cette diversification divergent selon les cultures et les organisations familiales, chacune pouvant satisfaire à sa manière le besoin d’attachement lorsque son fonctionnement n’est pas altéré. C’est ce que nous appelons la diversité de l’attachement. À partir de vignettes cliniques relatant des « ratés » du processus d’attachement ou de sa diversification nous montrons comment la connaissance et la prise en compte par les thérapeutes de la diversité des modèles d’organisation familiale sont utiles aux tentatives de réparation, voire de création d’un lien d’attachement lorsque celui-ci ne s’est pas construit de manière adéquate ou a disparu.

Observées le plus souvent sous l’angle de l’accès à l’école primaire et/ou secondaire, les inégalités scolaires entre filles et garçons en Afrique ont fait l’objet de nombreuses recherches depuis les années 1970. Plus qu’une distinction filles/garçons, cet article propose une lecture à partir du genre du quotidien des enfants dans deux écoles primaires de Cotonou. Adossé à des observations et des entretiens avec des instituteurs, il montre comment l’entrée en classe, le placement des enfants sur les bancs, les interactions entre élèves et enseignants, la distribution des tâches sont régis par les représentations que les instituteurs se font des qualités et attributions des filles versus des garçons. Il apparaît alors que l’école n’est pas un lieu de changements, mais plutôt de maintien des normes de genre en vigueur à l’extérieur dans la société environnante.
Repenser l’accompagnement scolaire des filles au Sénégal : la Maison de l’éducation à Ziguinchor comme dispositif de (re)mise à l’école

Malgré les progrès réalisés en matière de parité filles-garçons dans l’accès et le maintien à l’école en Afrique, des inégalités persistent comme au Sénégal où les normes sociales de genre dominantes exposent davantage les filles que les garçons au cumul de sollicitations familiales et sociales, entre travail rémunérateur et travail domestique. Plutôt que de se limiter, comme la plupart des programmes en place, à retenir dans le système scolaire des élèves à risque de décrochage ou à favoriser l’accès à l’école des filles dès le plus jeune âge, le dispositif de la Maison de l’éducation (MDE), mis en place depuis 2014 à Ziguinchor par l’association Futur au présent, vise, en les accompagnant durant tout le cycle élémentaire, à permettre le retour à l’école publique de filles qui en sont déjà sorties ou d’un âge trop avancé pour y entrer normalement. Cet article prend appui sur une étude qualitative des trajectoires individuelles des filles qui sont passées par le dispositif de la MDE, pour en analyser les effets positifs, mais aussi poser la question de sa généralisation possible.
La remunicipalisation du service public de l'eau à Montpellier : un processus de refocalisation d'outils de gestion du privé
Authors: Guérin-Schneider Laetitia , Colon Marine
Published: March 2023

L'introduction dans une organisation publique d'outils issus du privé renforce-t-elle nécessairement la logique de marché au détriment des autres logiques préexistantes ? Cette question est explorée au prisme de la sociologie néo institutionnelle par une analyse longitudinale et micro-analytique du processus de création d’une régie des eaux dans le sud de la France. Ce champ de l’eau urbaine se caractérise par une influence marquée de la logique de marché qui s'explique à la fois par la diffusion du Nouveau Management Public dans la gestion publique locale et par la présence ancienne des entreprises privées de l’eau. D'autres logiques idéalestypes coexistent (État et profession de l’ingénieur, qualifiée ici de technique). Une recherche-intervention de neuf ans (2012-2020) a permis la constitution d’un matériau empirique riche et original, centré sur la conception des dispositifs de gouvernance et des outils de pilotage de la régie. Les résultats mettent en évidence un processus d’intégration de logiques que nous qualifions de « refocalisation d'un outil de gestion ». À un grain grossier, c’est-à-dire analysés de manière grossière, à travers leur catégorie générique, ces outils inspirés du privé semblent avoir été sélectionnés par référence à la logique de marché. En revanche, à un grain fin, celui des spécifications détaillées, l’analyse révèle que ces mêmes outils véhiculent les logiques de l’État et technique. L’acteur porteur de la création de la régie, un élu local, a joué un rôle essentiel pour refocaliser les outils de gestion du privé sur des logiques conformes à son projet politique. Cet article met donc en lumière un processus de construction d’un sens commun aux acteurs, permettant de lever les éventuelles tensions dues à la coexistence de multiples logiques.
L’acculturation footballistique du club de Bischwiller au tournant de la Grande Guerre (1911-1923)
Authors: Schon Lucas , Saint-Martin Jean
Published: March 2023

Entre 1911 et 1923, la petite ville de Bischwiller, située à 20 km au nord de Strasbourg, voit s’implanter progressivement des pratiques footballistiques du fait de nombreuses circonstances favorables. Ce processus d’acculturation est rendu possible notamment par l’action permanente des militaires français, véritables passeurs culturels grâce à leur activité footballistique qui représente autant d’opportunités pour renforcer les contacts entre « l’en-groupe » dont ils font partie et les membres du groupe « receveur », la population bischwilleroise. Porté par un comité dynamique et stable, un public énergique, une municipalité consciente des apports du football pour son image et ses habitants, le Football Club de Bischwiller – FCB 07 – voit ses succès se renforcer d’année en année. Ceux-ci sont d’une part sportifs, à travers le titre officieux de 1923 puis le titre officiel de champion d’Alsace en 1925. D’autre part, ces succès se concrétisent lors des nombreuses épopées en coupe de France ou des multiples victoires lors des matchs de « gala ». Le rôle de « l’en-groupe », composé de civils formés et des militaires, semble ici primordial pour inscrire dans le temps un transfert culturel que bon nombre de Bischwillerois souhaitent et dont les Affiches de Bischwiller , qui constitue ici la source principale d’investigation, rendent régulièrement compte. En définitive, deux facteurs expliquent le succès de ce transfert culturel par le biais du FCB 07. Le premier correspond d’une part à la présence et l’activité, sur le territoire bischwillerois, des membres de « l’en-groupe » à la fois composés de civils ayant été en contact d’Anglais ou d’une culture anglophile et footballistique. D’autre part, par le fait que ce sont les militaires qui œuvrent à démocratiser le football à Bischwiller, non seulement durant les quatre années de guerre, mais aussi dès son lendemain. Le second facteur de ce contexte propice à une acculturation footballistique massive est celui de l’espace-temps particulier de la ville de Bischwiller qui, par sa dimension patriotique, festive, industrielle et son attachement aux valeurs de modernité, tourne résolument le dos au modèle traditionnel germanique, imposé du temps de la première annexion et auquel les Bischwillerois ont eu des difficultés à se soumettre.
Intraoperative Greater Trochanteric Fractures During Revision Total Hip Arthroplasty May Not Always Need Surgical Fixation

Many fixation techniques have been described to manage intraoperative greater trochanteric (GT) fractures during revision total hip arthroplasty (rTHA), but complications such as broken hardware and bursitis are common. The purpose of this study was to determine whether surgical fixation of an intraoperative GT fracture resulted in improved outcomes in rTHA. We reviewed a consecutive series of 1442 rTHA patients at our institution from 2008 to 2019. We identified all patients with an intraoperative GT fracture and noted whether the fracture was fixed surgically or left without fixation. Demographics, comorbidities, complications, radiographic union, and dislocations were compared between the groups. Of the 44 (3%) intra-operative GT fractures identified, 23 (52%) underwent fixation, most commonly with claw plates (8 patients) and cables (10 patients). There were no differences in the rates of radiographic union (86% vs 100%,
P
=.100), dislocations (4% vs 10%,
P
=.599), or re-revision (10% vs 13%,
P
=1.000) between the groups. Patients undergoing fixation had a higher rate of bursitis postoperatively, but it was not significant with the numbers available (35% vs 10%,
P
=.072). Our cohort of GT fractures at a large revision referral institution represents the largest reported series of GT fractures during rTHA. Surgical fixation in rTHA did not show improved outcomes in terms of dislocation, re-revision, and radiographic union compared with those fractures that were not fixed. There was a trend toward increased postoperative bursitis in the group undergoing surgical fixation. Further research is needed on this topic, as the number of rTHAs continues to increase. [

How do classroom-turnover times depend on lecture-hall size?

Academic spaces in colleges and universities span classrooms for $ 10 $ students to lecture halls that hold over $ 600 $ people. During the break between consecutive classes, students from the first class must leave and the new class must find their desks, regardless of whether the room holds $ 10 $ or $ 600 $ people. Here we address the question of how the size of large lecture halls affects classroom-turnover times, focusing on non-emergency settings. By adapting the established social-force model, we treat students as individuals who interact and move through classrooms to reach their destinations. We find that social interactions and the separation time between consecutive classes strongly influence how long it takes entering students to reach their desks, and that these effects are more pronounced in larger lecture halls. While the median time that individual students must travel increases with decreased separation time, we find that shorter separation times lead to shorter classroom-turnover times overall. This suggests that the effects of scheduling gaps and lecture-hall size on classroom dynamics depends on the perspective—individual student or whole class—that one chooses to take.
Gender in Climate Change: Safeguarding LGBTQ+ Mental Health in the Philippine Climate Change Response From a Minority Stress Perspective
Authors: Alibudbud Rowalt
Published: March 2023

Climate-related events unevenly affect society, worsening mental health disparities among vulnerable populations. This paper highlights that lesbians, gays, bisexuals, transgender, queers, and other individuals identifying as sexual and gender minorities (LGBTQ+) could be considered a climate-vulnerable population in the Philippines, one of the most climate-vulnerable countries. As such, this paper elucidated that LGBTQ+ Filipinos can be marginalized in climate response efforts due to their sexual orientation and gender minority identities. According to the minority stress theory, discrimination against LGBTQ+ individuals may predispose them to mental health problems. Thus, there is a need to institute an LGBTQ+ inclusive mental health response for climate-related events to address discrimination against LGBTQ+ individuals and uphold their mental health.

This paper discusses the design of a net-zero single-family house in Chattanooga, Tennessee, which was proposed for the 2022 Solar Decathlon Design Challenge entry. The site was in a 100-year flood zone and registered as a national and local historic district. The interdisciplinary team consisted of University of Tennessee Chattanooga (UTC) students from the interior architecture and engineering departments who embraced the challenges of the local climate and the restrictions of the historic district guidelines. This entry, Moc House, focused on the integration of passive design and active HVAC systems including photovoltaic systems in the process. In responding to recent housing market changes in Chattanooga due to the COVID-19 pandemic, a young professional couple in their 30s who have two children was identified as the target market which guided the space planning. Market analysis, including ROI, was conducted in addition to construction cost calculations. Building materials were selected to enhance the durability and resilience of the house structure. Finally, energy analysis was conducted to check the project’s Home Energy Rating using Ekotrope and found it less than zero.
Rigging Design and Rope Design as Artistic Practice
Authors: Rombout Saar
Published: March 2023

This is an audio-visual essay based on the thesis that I wrote for my MFA in Contemporary Circus Practices at Stockholm University of the Arts. This project was dedicated to preliminary research that opens up a conversation about what creative rigging and rigging design can be in circus. It discusses what roles the rigger can have and how rigging can be not only a technical aspect, but also an essential element in the artistic process. In circus, the way you move is closely linked to the apparatus you use. By designing new apparatuses or rigging constructions for circus artists to intra-act with, I create new ways to move. An installation can work partly as a score or a script for the performers to interpret and explore, rather than just an instrument that humans use to do tricks. I specifically work intensively with ropes as a performer, researcher and rigger. Working with ropes and knots is often seen as a craft, not an art form, but I think it can be both. Cela est un essai audio-visuel qui prend pour base la thèse que j’ai rédigée pour mon master en pratiques du cirque contemporain à L’Université des Arts de Stockholm. Ce projet s’est dédié à des recherches préliminaires qui ont ouvert un débat sur le gréement créatif et ce que le design des gréements peut faire. Cet essai commente les rôles possibles pour les gréeurs, et comment le gréement peut-être non seulement un aspect technique, mais aussi un élément essentiel dans le processus artistique. Dans le cirque, la façon dont on bouge est étroitement liée à l’appareil qu’on emploie. En faisant des machines neuves ou des constructions de gréements avec lesquelles les artistes de cirque peuvent travailler, je crée des nouvelles façons de bouger. Une installation peut fonctionner partiellement comme musique ou comme un scénario pour les artistes à interpréter et explorer, bien plus qu’un simple instrument qu’utilise des êtres humains pour jouer des tours. Je travaille activement et précisément avec des cordes comme interprète, chercheur et gréeur. Le travail des cordes et des nœuds est souvent vu comme être un métier et non pas un art, mais je crois que quant au gréement, les deux possibilités sont envisageables.
