Accuracy Assessment of Post-processing Kinematic Georeferencing Based on Real-time Kinematic Unmanned Aerial Vehicle and Structure-from-motion Photogrammetry: Topographic Measurements of a Riverbed in a Small Watershed with a Check Dam
Authors: Hayamizu Masato , Nakata Yasutaka
Published: November 2021

To obtain an accurate digital surface model of the small watershed topography of a forested area while reducing time and labor costs, we used a consumer-grade unmanned aerial vehicle (UAV) with a build-in real-time kinematic global navigation satellite system. The applicability of structure-from-motion (SfM) multi-view stereo processing with post-processing kinematic (PPK) correction of the positional coordinate data (the UAV-PPK-SfM method) was tested. Nine verification points were set up in a small (0.5 km2) watershed, based on a check dam in the headwaters of a forest area. The location information of the verification points extracted from the digital surface model acquired by UAV-PPK-SfM and the overall working time were compared with the corresponding location information and working time of a traditional field survey using a total station. The results showed that the vertical error between the total station and each verification point at an altitude of 150 m ranged from 0.006 to 0.181 m. The working time of the UAV-PK-SfM survey was 10 % of that of the total station survey (30 min). The UAV-PPK-SfM workflow proposed in this study shows that wide-area, non-destructive topographic surveying, including fluvial geomorphological mapping, is possible with a vertical error of ±0.2 m in small watersheds (<0.5 km2). This method will be useful for rapid topographic surveying in inaccessible areas during disasters, such as monitoring debris flow at check dam sites, and for efficient topographic mapping of steep valleys in forested areas where the positioning of ground control points is a laborious task.
A varying-gain ZNN model with fixed-time convergence and noise-tolerant performance for time-varying linear equation and inequality systems
Authors: Zhang Miaomiao
Published: November 2021

In this paper, a varying-gain zeroing (or Zhang) neural network (VG-ZNN) is proposed to obtain the online solution of the time-varying linear equation and inequality system. Distinguished from the fixed-value design parameter in

the original zeroing (or Zhang) neural network (ZNN) models, the design parameter of the VG-ZNN model is a nonlinear function that changes with time. The VG-ZNN model composed of the new time-varying design parameter we proposed can achieve fixed-time convergence and tolerate time-varying bounded noise and time-varying derivable noise. The theoretical detailed analysis of the convergence and robustness of the VG-ZNN model are given.

Authors: Araji Ghada , Maamari Julian , Ahmad Fatima Ali , Zareef Rana , Chaftari Patrick , Yeung Sai-Ching Jim
Published: November 2021

The discovery of immune checkpoint inhibitors (ICIs) has revolutionized the care of cancer patients. However, the response to ICI therapy exhibits substantial interindividual variability. Efforts have been directed to identify biomarkers that predict the clinical response to ICIs. In recent years, the gut microbiome has emerged as a critical player that influences the efficacy of immunotherapy. An increasing number of studies have suggested that the baseline composition of a patient's gut microbiota and its dysbiosis are correlated with the outcome of cancer immunotherapy. This review tackles the rapidly growing body of evidence evaluating the relationship between the gut microbiome and the response to ICI therapy. Additionally, this review highlights the impact of antibiotic-induced dysbiosis on ICI efficacy and discusses the possible therapeutic interventions to optimize the gut microbiota composition to augment immunotherapy efficacy.

Historie awangardy filmowej na nowo (o)pisane
Authors: Zawojski Piotr
Published: November 2021

Omawiany tom – Historie filmu awangardowego. Od dadaizmu do postinternetu (2020) pod redakcją Łukasza Rondudy i Gabrieli Sitek – jest efektem projektu edukacyjnego „Akademia filmu awangardowego” realizowanego przez Fundację Okonakino i Muzeum Sztuki Nowoczesnej w latach 2019-2020. Autor zwraca uwagę na próbę rewizji dotychczasowych ustaleń dotyczących awangardy filmowej wyrażającą się przede wszystkim w dowartościowaniu twórczości artystek dotąd często pomijanych lub niedocenianych. Tematyczno-chronologiczna kompozycja całości jest rozpięta między tradycją kina awangardowego od jego początków w XX w. do najnowszych realizacji wykorzystujących wideo oraz nowe media, ze szczególnym uwzględnieniem optyki feministycznej, queerowej, klasowej i postkolonialnej, oraz badaniem związków filmu dokumentalnego i awangardowego. Reinterpretacja wcześniejszych odczytań filmu awangardowego i prezentacja mało znanych fenomenów zarówno historycznych, jak i współczesnych stanowi o atrakcyjności publikacji.
Radosne związki formy i treści („Chłopcy na piasku” Wakefielda Poole’a)
Authors: Piotrowski Grzegorz
Published: November 2021

Opozycja treści i formy jest jednym z fundamentów (i złudzeń) klasycznej estetyki. Pojęcia te nie tylko funkcjonują jako przeciwieństwa i korelaty, ale bywają też „wymazywane” – jak w filmowej pornografii, czyli kinie mechanicznie replikowanej formy, kinie bez treści lub z treścią schematyczną i pretekstową. W historii filmu porno szczególne miejsce zajmują jednak Chłopcy na piasku Wakefielda Poole’a (1971). Film ten neguje formalne schematy pornografii, które reżyser zastępuje formą autorską, odsyłającą do tradycji modernizmu i sztuki gejowskiej oraz dialogującą z różnymi nurtami kina. Dzięki specyficznej organizacji czasu, lirycznej tonacji i wizualnej jednolitości Chłopcy… są więc filmem formy, ale à rebours; forma ta generuje treść. Dzieło Poole’a ma bowiem wymowę emancypacyjną i transgresyjną. Jego wartość artystyczna polega zaś na tym, że cielesność i seksualność są przepisywane na autorski język filmowy, metaforyzowane i kontekstualizowane w polu skojarzeń kulturowych.
The Category of System in David Bordwell’s Concept of Film Aesthetics
Authors: Przylipiak Mirosław
Published: November 2021

The aim of this paper is to analyse the role played by the category of system in the early books of David Bordwell. They have exerted an enormous influence on the understanding of film aesthetics, but little space has been devoted to their methodological background, including the category of system. In Film Art: An Introduction (1979), all elements of film form have a systemic character, which is visible in the chapter titles, such as “Form as System” or “Narration as a Formal System”. In The Classical Hollywood Cinema, the film aesthetics is based on systems of narrative logic, time and space. In Narration in the Fiction Film, the systems of syuzhet and style are foregrounded. Bordwell’s fascination with systems is rooted undoubtedly in their popularity in the 1970s. But do Bordwellian notions really fulfil the criteria of system theory, especially in its newer version, with such notions as chaos, feedback loop, self-regulation and others? Perhaps even Bordwell himself is not certain of that, since the word “system” disappears from recent editions of Film Art: An Introduction.

Published: November 2021

The efficacy of two isolates of bacterial bioagents and two fungicides via, Rhizoctonia solani isolates were evaluated in vitro. In the dual culture assays, significance inhibition ratio of R. solani hyphal growth was obtained in all treatments of Pesudomonas fluoresnces and Bacillis subtilis compared to control. Also, Bacillus subtilis exhibit the highest significant suppression for the mycelial growth of R. solani isolates more than Pseudemonas fluorescens, and the ratios of inhibition differed according to the bioagents and R. solani isolates similar to those results in antifungal activity technique. The volatile metabolite studies revealed that in the first period (three days) inhibition percentage significantly differed according to the tested isolates of R. solani and the applied bioagents, B. subtilis gave the highest inhibition (57.41%) in R. solani isolate 3. Similarly in P. fluoresnces treatments, the highest inhibition was (57.41%) was detected in isolate 3 of R. solani considering that the second tested time period (five day inoculation). B. subtilis showed highest inhibition value on isolate 1, on the other hand P. flouresnce showed high value of inhibition on isolate 2, whereas the lowest inhibition values were produced on isolate 1.Non volatile activity both bacterial bioagents isolates showed different values of inhibition on R. solani isolates. On the other hand, Rezolex was most effective against R. solani at two concentrations (0.2 and 0.3), however Topsin-M showed fluctuate inhibition values at two concentration used (0.04% and 0.075%). Further incubation of plates showed suppressed the formation of sclerotia by all the antagonists tested. The results implied that the extent of inhibition by B. subtilis and P. fluoresnces rovides the use of excellent potential antagonists capable of controlling the R. solani in vitro.

To degrade the polysaccharide with high molecular weight the effectiveness of ultrasound for carboxymethyl cellulose (CMC) in aqueous solution has been studied at a time of 60 min and temperature of 25 ̊C and for polymer solution with concentration up 0.1 g/L. The Huggins equation was appropriate to apply to the intrinsic viscosity of CMC before sonication to understand the influence of salt on degradation, CMC solution was premixed with 0.1 M NaCl, before ultrasonication. Developed a kinetic model, successfully implement to predict and quantify rates of degradation and efficiency. The values of reaction rate constants and reaction orders were found related to the salt and the concentration used, suggesting that, the presence and absence of salts could increase or decrease the degradation by ultrasonic radiation through adjusting the molecular conformation of CMC
The Role of F-doping and the Sintering Temperature on the Superconductivity and Lattice Constants in LaOFeGe Compounds
Authors: T. M. Fayez T. M. Fayez
Published: November 2021

The most prominent indicator of superconductivity is the superconducting transition temperature (Tc) that refers to three points. The onset transition temperature (Tonset) is defined as the deviation point away from the ρ(T) straight line (onset of the drop in resistivity). The midpoint transition temperature (Tmidpoint) is defined as the temperature, where resistivity becomes 50% of its value at Tonset. The zero-resistance transition temperature (Tρ≈0) is defined as the temperature, in which the resistance is identically zero or only immeasurably small. These indicators of temperatures associated with some factors. In this article, the X-ray diffraction and electrical resistivity measurements of LaO1-xFxFeGe samples are reported. This compound was successfully synthesized via a solid state reaction method with the presence of germanium Ge in the conduction layer. Furthermore, some factors affecting the superconducting transition temperature were studied, which are the F-doping dependence of Tonset, Tmidpoint, and lattice parameters, and sintering temperature dependence of Tonset.

Published: November 2021

The notorious weed, jimson weed (Datura stramonium L.) is a hallucinogenic plant that is both toxic and medicinal. The presence of tropane alkaloids, which contain a methylation nitrogen atom (N-CH3) and inhibit neurotransmitters in the brain, is thought to be responsible for the plant's neurotoxicity. Toxic symptoms have been linked to the recreational use of D. stramonium, according to ethnomedicine. This investigation has been designed to examine the toxicity and describe the possible changes in the structural function of vital organs, following the orally intubation of non-lethal doses of D. stramonium leaves crude aqueous extract. Through preliminary trials, crude aqueous extract. Of 200 mg leaves per kilogram body weight was established as a tolerable non-lethal dose. Three doses 0.36, 0.7, and 4 mg/kg were orally weekly, administered to the male mice in a 0.1 ml volume. Acute toxicity studies were accomplished through oral intubation of three dosages in each case. Observation and mortality were reported for 24 .48, 72 hours. Prolonged toxicity was performed through the administration of weekly, single doses oral for 40 days. The observation was made on the mice's testis weight and histological abnormality of a testis organ.

Post-Great-Recession Human Migration Patterns in the U.S.: The Overlooked Impacts of Entrepreneurial Activity and Personal Freedom
Authors: Cebula Richard J.
Published: November 2021

Effectively no scholarly research has been published in peer-reviewed journals on the potential migration impacts of environments that are more conducive to entrepreneurship. Similarly, the potential migration impact of personal freedom also is essentially ignored in the literature. This study seeks to add to the literature by investigating the impacts of both entrepreneurial activity and personal freedom on state in-migration patterns. Using a panel dataset for the post-Great Recession period 2010-2017, the empirical analysis reveals that all three of the Kauffman indices of entrepreneurial activity are found to exercise a positive and statistically significant impact on both net in-migration and gross in-migration. In addition, the index of overall personal freedom is found to exercise a positive and statistically significant impact on both of these in-migration measures. Thus, it appears that there may be good reason for future migration studies to take such variables into account when seeking to explain, understand, and predict migration patterns in the U.S..
The Co-Evolution of Global Legitimation and Technology Upgrading: The Case of Huawei
Authors: Wu Sihong , Fan Di , Su Yiyi
Published: November 2021

This study explores the underlying relationship between acquisition of global legitimacy and the search for technology upgrading by Chinese multinational enterprises (MNEs). Using Huawei’s investment in Russia, Kenya, the United Kingdom and Canada as an in-depth case study, we observe that through corporate social responsibility (CSR) activities in foreign markets and engaging with local community, Chinese MNEs can acquire global legitimacy and gradually catch up with industry leaders. However, the process of global legitimation and innovation continues to evolve. We find that, together with engaging in CSR activities, acquisition of sophisticated knowledge and creation of innovation bring more legitimacy challenges to these firms. Thus, we suggest that Chinese MNEs’ global legitimation and innovation processes are closely coupled and mutually influential, resulting in co-evolution.
Financial Frictions and Macroeconomy During Financial Crises: A Bayesian DSGE Assessment
Authors: Etoundi Atenga Eric Martial , Abdo Maman Hassan , Mougoué Mbodja
Published: November 2021

The recent global financial crisis and the Eurozone sovereign default have rekindled the debate on the interactions between the real sector and the financial sphere. The present paper provides an assessment of the role of financial frictions on business cycles in Canada, the Euro Area, the U.K., and the U.S. during these recent financial crises using an extension of the DSGE methodology described by Merola (2015). The main goal is to examine whether and the extent to which those crises enhanced the contribution of financial frictions in driving macroeconomic fluctuations. The models’ properties are examined with posteriors distributions, variance decomposition, and historical decomposition. Posteriors distributions show that the role of real shocks in driving macroeconomic fluctuations decrease with the incorporation of financial frictions in the core DSGE model. Variance decomposition shows that financial frictions and financial shocks affect the business cycle through investment. The empirical estimates also suggest that the contribution of financial frictions and financial shocks in driving investment increases during the global financial crisis.

BACKGROUND: Rheumatoid arthritis (RA) prevalence according to the worldwide epidemiological data varies from 0.4% to 1.3%. The disability and mortality rate in RA is high. RA clinic is various, and compiles from articular and systemic manifestations.

AIM: The aim of our study was to investigate the clinical course of RA in Kazakhstani patients living in North region of our country.

METHODS: The 81 women at the age of 30–55 years with a verified diagnosis of RA who have lived in Kazakhstan for at least 10 years were recruited to the study. All participants were examined by the rheumatologist and a standard laboratory examination was carried out. Statistical analysis was conducted in IBM SPSS Statistics 26 software (IBM.USA;1).

RESULTS: The statistically significant higher frequency of erosive radiological stages, bone ankylosis (χ2 = 18.070 df = 6 p = 0.005) was found in seropositive (rheumatoid factor [RF]+) anti-citrullinated protein/peptide antibody positive (ACPA+) subgroup. The correlation analysis showed strong association between certain RA form activity and inflammatory markers, as well as disease triggers. The discriminant model which predicts the stage of radiological damage was obtained. The sensitivity of model in predicting X-ray Stage I-71.6%, Stage II-29.4%, Stage III-37.5%, and Stage IV-63.6%.

CONCLUSION: The debut of the RA on average occurred in the third decade of the patients’ life. The joint syndrome had a more unfavorable character RF+ACPA+ patients’ subgroup; however, RF+ACPA-negative (ACPA-) subgroup also showed a predisposition to poorer prognosis. The obtained discriminant model may be useful for RA patients’ management.
A perennial invader’s seed and rhizome differ in cold tolerance and apparent local adaptation

Published: November 2021

Extreme cold plays a key role in the range boundaries of plants. Winter survival is central to their persistence, but not all structures are equally susceptible to frost kill and, therefore, limiting to distributions. Furthermore, we expect intraspecific variation in cold tolerance both within and among tissue types. In a laboratory setting, we determined freezing tolerances of two overwintering propagule types – seeds and rhizomes – of the globally invasive Johnsongrass (Sorghum halepense), testing apparent emergence and electrolyte leakage as a proxy for cell death. We used 18 genotypes from agricultural and non-agricultural habitats spanning the climatic extremes occupied by Johnsongrass in the US. Single node rhizome fragments had an average LT90 of -5.1 °C with no significant variation based on home climate or ecotype. Seeds frozen at -85 °C suffered a decline in germinability to 10% from 25% at 22 °C. Population origin did not affect seed response to any temperature. However, non-agricultural seeds germinated more and faster than agricultural seeds from the coldest climates, with a reversed relationship among warmest origin seeds. Regardless of ecotype, seeds from the cold/dry and wet/warm sectors of Johnsongrass’s range germinated more and faster. Drastic differences in cold tolerance between seeds and rhizome and evidence for seeds’ local adaptation to land use and climate suggest that its spread is likely limited by winter rhizome survival, as well as adaptability of germination behavior to longer winters. These findings shed light on Johnsongrass’ dispersal dynamics and help identify future avenues for mechanistically understanding its range limitation.
Diagnosing diagnoses – can we improve our taxonomy?
Authors: Borkent Art
Published: November 2021

Taxonomic diagnoses should be clear but minimal statements that precisely distinguish a given specimen from other taxa at the same stage of development (e.g., pupa, adult female, egg). Presently, most diagnoses are of uncertain value. It is a great advantage for readers to be able to simply and confidently confirm their identifications after using a key.
Althusser pour l’avenir : le programme inachevé d’une science sociale marxiste
Authors: Karsenti Bruno
Published: November 2021

à la suite de Mai 68, Althusser rédige Sur la reproduction, dont ne sera publié qu’un échantillon, le chapitre consacré aux « Appareils idéologiques d’État ». Nous montrons, en reprenant la genèse et le contexte d’écriture du manuscrit complet, que son intention rectrice est de déterminer les bases de ce qui mérite le nom de « science sociale marxiste ». Un tel projet ne va nullement de soi, ni lorsqu’on revient aux principes du marxisme, ni dans le contexte de Mai 68, ni encore aujourd’hui. Il est pourtant fondamental aussi bien pour l’analyse des sociétés capitalistes que pour la formulation et la mise en œuvre d’une position critique. Il convient alors de diagnostiquer les résistances auxquelles un tel projet se heurte pour s’efforcer de les lever. Elles ont trait aux concepts d’État et d’idéologie, qu’une perspective de science sociale investit d’un nouveau sens, requalifiant en cela la visée et les implications politiques de la critique du capitalisme.
Religion et science
Authors: Crépel Pierre
Published: November 2021

Deux sociologues québécois, Yves Gingras et Kristoff Talin, viennent de publier une étude dans laquelle ils affirment, avec une réelle assurance, que « plus de religion égale moins de science ». Ainsi la personne athée se verrait dotée d’une plus grande compétence. L’auteur émet dans cet article quelques doutes et objections sur la méthode et sur le résultat.
Le statut ambigu de bénévole des pairs-aidants LGBT travaillant pour la santé sexuelle en Côte d’Ivoire
Authors: Briard Jean-Yves
Published: November 2021

Pour lutter contre le vih , des ong recrutent des pairs-aidants («  ep  ») dans les populations les plus exposées au risque de contamination. Ceux-ci travaillent sous un statut ambigu de « bénévole sous contrat ». L’auteur a mené en Côte d’Ivoire trois interventions en psychodynamique du travail, visant à explorer le vécu au travail de ces ep lgbt , sous l’angle de la perspective du care . Même si la faible reconnaissance financière liée au statut peut être compensée par d’autres avantages, l’emploi comme stigmate semble nuire à une authentique discussion sur l’organisation du travail. L’article montre aussi un malentendu entre les objectifs parfois contradictoires qui leur sont donnés et ce qui mobilise les ep au travail. Tout ceci a des conséquences néfastes sur l’efficacité de ce dispositif de lutte contre le vih alors que des ep ont des propositions encore actuellement inaudibles pour concilier une meilleure efficacité et l’amélioration de leur condition.
Propédeutique pour des psychanalyses gratuites
Authors: Audasso Mathilda
Published: November 2021

Les lieux de transmission de la psychanalyse diffusent l’idée qu’une analyse en libéral ne saurait être complètement gratuite. Celle-ci est sous-tendue par le présupposé économique hégémonique que le prix (même faible) investi garantit l’implication des patients dans leur travail analytique. La référence à la valeur d’une analyse chez Freud est ambiguë car elle recouvre deux niveaux hétérogènes (matériel et symbolique) qui recoupent les positions dissymétriques de l’analyste et du patient. Il convient dans ce travail d’éprouver cette limite. Par la suite, le modèle du don chez Marcel Mauss pourrait constituer un cadre heuristique pour le ou la psychanalyste qui voudra proposer une cure gratuite. Cette réflexion se propose comme une propédeutique qui puisse permettre des discussions d’ordre épistémologique et pratique.
Bénévole : un métier impossible ?
Authors: Bineau Jacques
Published: November 2021

Bien que l’action bénévole soit ignorée ou largement méconnue dans nos sociétés, elle n’en est pas moins réelle. L’exercice de son métier de psychosociologue a amené l’auteur à intervenir dans le secteur de l’action sociale et à accompagner acteurs et structures dans des moments de crise et dans la longue durée. Les bénévoles sont soumis à des tensions sur différents registres : psychiquement, ils sont partagés entre la gratuité de leur engagement et leurs intérêts propres, les relations avec les salariés sont délicates, particulièrement dans le rôle d’employeur, les références démocratiques laissées de côté dans la conduite de l’organisation ouvrent la porte à une gestion technocratique dans laquelle les finalités institutionnelles du projet d’action peuvent être oubliées. Ces difficultés peuvent décourager le bénévole et le cantonner à un rôle de second où il peut être instrumentalisé, mais ces obstacles peuvent aussi être surmontés. L’intervention psychosociologique peut aider le bénévole à s’autoriser de sa propre pensée, à développer son autonomie d’action, à accepter d’exercer l’autorité qui lui revient dans un rôle de dirigeant démocrate.
Un engagement bénévole fragilisé dans une institution en crise : le cas des prud’hommes
Authors: Béroud Sophie , Meynaud Hélène-Y.
Published: November 2021

Bien qu’il ait été rarement analysé de cette façon, l’engagement des conseillers prud’hommes repose essentiellement sur du bénévolat. Ces derniers effectuent un travail quasi gratuit pour faire vivre cette juridiction atypique. Cependant, les évolutions récentes du droit du travail et la fragilisation de l’institution ont rendu leur mandat plus difficile. Depuis 2018, on observe un nombre significatif de postes vacants et de démissions en cours de mandat qui attestent un véritable malaise au travail. Une étude de terrain décrit les diverses facettes du (dés)engagement des démissionnaires, leur rapport aux rétributions matérielles et symboliques. Elle montre aussi comment l’exigence de parité femme-homme dans les listes de conseillers proposées à la nomination n’a pas nécessairement facilité l’intégration des femmes.
Stagiaires-bénévoles et accompagnement professionnel : coexister ou coopérer ? Une expérience en chantier d’insertion
Authors: Mercier-Millot Sophie
Published: November 2021

Cet article est fondé sur une expérience de terrain en tant que bénévole dans le cadre d’un stage professionnalisant dans un atelier chantier d’insertion ( aci ). Situé dans le champ conceptuel de la psychologie sociale clinique, cette contribution analyse la façon dont la gratuité du travail des stagiaires-bénévoles articulée aux valeurs d’engagement consubstantielles du bénévolat précarise le travail salarié et fragilise la coopération des permanents et des bénévoles. L’article ouvre une réflexion sur le processus de naturalisation des compétences mobilisées dans l’accompagnement qui permet qu’une telle dévalorisation puisse intervenir.
Le bénévolat d’entreprises : un renouvellement de l’engagement dans l’action collective pris entre recherche de sens et essor des entreprises sociales
Authors: Morel Camille , Poulain Sébastien
Published: November 2021

Les associations détenaient le monopole de la délégation de service public en assumant des missions d’intérêt général et accueillaient donc l’ensemble des bénévoles qui s’impliquaient dans des causes dites sociales. Mais les lois ess et pacte ont confirmé une évolution du rôle social confié aux entreprises en les légitimant dans leur position au service de l’intérêt général. Dès lors, les entreprises commencent à s’intéresser aux bénévoles et vice versa, occasionnant ainsi un renouvellement des formes de l’engagement. L’objet du présent article est d’étudier ces nouveaux « bénévoles d’entreprises » et d’analyser les modalités de ces contributions en s’intéressant à leur vécu de cette évolution.
Réflexions sur un projet de danse intergénérationnel
Authors: Bourgeois-Guérin Élise , Lyke Claire , Lachaîne Audrey , Rousseau Cécile
Published: November 2021

À plusieurs égards, la danse peut exprimer et transformer des liens interpersonnels et sociaux. Le présent article explore cette idée en s’appuyant sur un projet de danse mené à Montréal en 2017 dans un quartier pluriethnique faisant face à des enjeux de pauvreté. Ce projet s’appuyait sur l’hypothèse que les liens intergénérationnels et intercommunautaires se font écho et se métamorphosent mutuellement. Le cadre dans lequel le projet a pris forme sera d’abord posé et les défis qu’il a soulevés, notamment sur le plan de l’animation et du processus artistique, seront discutés. Finalement, l’article éclairera la façon dont certaines dynamiques entre centralité et marginalité s’y sont révélées
Ressorts et dynamiques de l’économie populaire : une lecture à partir du Sénégal
Authors: Ndiaye Sambou
Published: November 2021

Né en Occident, le vocable « économie sociale et solidaire » est de plus en plus utilisé dans le contexte africain sans que ne soient interrogés ses soubassements épistémologiques et historiques. Face à ce constat, l’auteur choisit de positionner dans le champ de l’économie populaire les initiatives d’autopromotion socio-économique portées par une diversité d’acteurs populaires, souvent en situation de vulnérabilité, qui s’investissent dans le système de production/distribution à travers une logique écosociale. Cet article, fondé sur une approche combinant épistémologie et sociologie économique, s’appuie sur des études de cas relevant de l’entrepreneuriat communautaire. Il révèle les ressorts spécifiques et la performance plurielle de l’économie populaire, toutefois fragilisée par sa gouvernance organisationnelle et un cadre institutionnel et stratégique qui n’incite pas à la reconnaissance de son caractère différentiel.
Les faillites des institutions mutualistes ou coopératives d’épargne et de crédit au Niger
Authors: Maichanou Ahamadou , Hamadou Daouda Youssoufou
Published: November 2021

Cet article a pour point de départ le constat inquiétant de la réduction drastique du paysage de la microfinance au Niger au cours de la décennie écoulée. Sur plus de 300 institutions de microfinance (IMF) créées depuis 1993, 39 seulement étaient encore en activité en 2020. L’engouement suscité par les IMF à partir de la décennie 2000 a fait place aux crises et aux faillites. Les auteurs tentent d’apporter des explications à cette situation en explorant trois pistes de réflexion : l’existence de risques importants (défaut de paiement, détournement des fonds, incapacité d’autofinancement) (I), une défaillance de la gouvernance et des problèmes d’agence (II), un jeu d’acteurs défavorable à l’épanouissement de la microfinance (III). L’accent est mis sur les institutions mutualistes ou coopératives d’épargne et de crédit (Imcec), qui sont les plus nombreuses et les plus touchées par les faillites.
