A Közbeszerzési Értesítő Plusz jelen számában ismertetett jogesetek az ajánlatkérő azon kötelezettségével foglalkoznak, amelynek alapján az alkalmassági követelményeket a közbeszerzés tárgyára kell korlátoznia és ezek mértéke a szerződés teljesítéséhez ténylegesen szükséges feltételeket nem haladhatja meg. Ezen előírás célja, hogy túlzott feltételek meghatározásával az ajánlatkérő a Kbt. garanciális szabályaival összhangban a piaci versenyt ne korlátozza. A Kbt. kógens rendelkezései a közösségi joggal harmonizált szabályok. A közbeszerzés közösségi alapelvei kimondják, hogy a beszerzést nem lehet azzal a szándékkal kialakítani, hogy az adott közbeszerzés kikerüljön a közbeszerzési irányelv hatálya alól, vagy mesterségesen korlátozza a versenyt. Akkor tekintendő úgy, hogy fennáll a verseny mesterséges korlátozásának esete, ha azzal a szándékkal határozták meg a beszerzés feltételeit, hogy ezzel egyes gazdasági szereplők méltánytalan előnyhöz jussanak, vagy ilyen hátrányt szenvedjenek. A jogorvoslati üggyel érintett tárgyak: A Döntőbizottság az ajánlatkérő által az ajánlati felhívásban előírt műszaki, szakmai alkalmassági feltételelek együttes hatása alapján megállapította, hogy az ajánlatkérő megsértette a Kbt. 65. § (3) bekezdését.

The second part establishes the relation between mobile cloud and big data and provides geo-dispersed big data application, including big data in mobile cloud sensing. Some open research questions that need to be investigate conclude this work.
Varied Simulation-based Stress Analyses on Zirconia All-ceramic Crowns
Authors: Porojan Liliana , Topală Florin , Porojan Sorin
Published: March 2022

The development of high-strength ceramics and its use in posterior areas has been a field of constant investigation. The performance of all-ceramic molar crowns fabricated with new CAD/CAM techniques is a subject of interest. The studies available in literature focused on the analysis of all-ceramic restorations failures, investigating several parameters involved on the tooth structure. The goal of this study was to investigate the stress distributions of zirconia - all ceramic crowns, under loads using varied stress distribution analyses. A static structural analysis was performed to calculate the stress distribution using the computer-aided engineering software. Equivalent stresses were recorded in the tooth structures and in the restoration for all these designs. Since ceramic materials exhibit brittle behavior, the first principal stress criterion was adopted to compare the stress values and distribution with those obtained for the first simulations. Under the same loading conditions, the stress distribution patterns for the zirconia all-ceramic crown using differential stress analyses exhibited similarities. Only the values are lower for the maximal principal stresses. The present study suggests that varied simulation methods are promising to assess the biomechanical behaviour of all-ceramic systems.
Taking the Financing Decision Considering the Comparison Between Their Own or Borrowed Funding and Public Funding
Authors: Emilia Calefariu , Alexandru Buda Traian
Published: March 2022

In this paper we present a method to determine the best financing solution for an enterprise with insufficient funding but with innovative ideas that need funding. We propose a model that calculates the total profit from the developed project. We take into consideration two cases, both for the analysis and also for model: first, financing with borrowed capital (loan capital financing) and second, public funding. As it will be shown, equity financing is a particular case of loan-based financing which is taken in consideration in this model. The proposed instrument is an objective one, so that managers can choose the most profitable path from the two situations presented. Many enterprises from the south-eastern countries are in this situation. They have innovative ideas but few possibilities for implementing them. The model is a fast decision instrument and it can be applied both at the level of large organizations and also for start-ups.

Gender Differences in Mathematics and Science Achievement of Eighth Grade Students in Ukraine on TIMSS 2011
Authors: Lisova Tetiana V. , Kovalchuk Yuriy O.
Published: March 2022

The purpose of the paper is in-depth analysis of gender differences in Ukrainian student achievement in mathematics and science on TIMSS 2011 results because the average scores similarity hides some significant differences between the achievements of boys and girls. Boys significantly outperform girls in some cognitive and content domains, while the benefit of girls never was significant. The procedure of Differential Item Functioning (DIF) on the basis of the Mantel-Haenszel method was used to test the fairness of assessment. The results show that the set of TIMSS 2011 items does not have any gender bias on Ukrainian students since there are insignificant number of items with large DIF, among which some favouring boys, and some favouring girls. Each of gender groups is equally represented among both stronger and weaker participants. Any significant relationship between the DIF size and the difficulty or type of the item is not detected. But the items in number, physics and earth science, and math problems on applying function in favour of boys. This is likely caused by the fact that in Ukrainian society still there is attitude to such fields of study as masculine.
peculiar competencia europea en I+D y el ejercicio de la subsidiariedad en el espacio europeo de investigación y en la política de I+D
Authors: Arizaga Ana
Published: March 2022

La política europea de investigación y desarrollo tecnológico tiene como objetivo la consecución del denominado Espacio Europeo de Investigación, es decir, de un mercado interior del conocimiento donde se despliegue la libre circulación de investigadores, conocimiento y tecnologías. Para ello, la Unión cuenta con una competencia compartida con los Estados Miembros, caracterizada por un régimen peculiar según el cual no opera el principio de preclusión. En el ejercicio de esta particular competencia, la Unión debe observar el principio de subsidiariedad. Un principio que en el contexto del Espacio Europeo de Investigación se manifiesta como el factor que determina las responsabilidades y los roles que la instancia supranacional debe asumir para lograr ese objetivo de optimizar el funcionamiento de un verdadero mercado interior del conocimiento. La evolución de la naturaleza competencial de la Unión en I+D que pasa de ser una competencia complementaria a una compartida, aunque de carácter híbrido, la inclusión del objetivo de consecución del Espacio Europeo de Investigación y la articulación del juego de la subsidiariedad precisamente en base a dicho objetivo son factores que explican el extraordinario crecimiento de la actuación de la Unión en el ámbito de la investigación, actuación que se traduce en la aprobación e implementación de los denominados Programas Marco de Investigación e Innovación, de carácter plurianual. El recientemente aprobado 9.º Programa Marco, el Horizon Europe, se ejecutará entre 2021 y 2027 y supondrá una inversión superior a los 90.000 millones de euros en investigación e innovación europeas .

Human and robot: technologization vs. humanization of noonomy
Authors:   Lomonosov Moscow State University, Porokhovskiy А.А.
Published: March 2022

The role of a man at various stages of the formation and development of capitalism is considered. It is shown how hired labor gradually turned from a factor of production into human capital and became a decisive element in the creation of new digital technologies. At the same time, there has been a significant change in the role and place of man in the economy and society. Noonomy can no longer rely solely on the private interest of capital, because technological fetishism has begun to threaten the very existence of a man. Artificial intelligence as a robot and in other forms claims to replace a man in many areas. Only a man himself is capable of transforming technologization into a modern support of humanization under the conditions of noonomy.
Scientific and technological progress and transformation of society: noonomy and noosociety. Part 1
Authors:   S.Y. Witte Institute for New Industrial Development, Bodrunov S.D.
Published: March 2022

The theory of Noonomy, based on the study of modern trends in technological and socio-economic development, allows us to identify the causes of the contradictions that modern civilization faces – economic, social, environmental, moral contradictions. However, noonomy not only reveals the background of these contradictions, but also shows the maturing objective possibilities of getting out of these contradictions, overcoming civilizational dead ends, choosing a path at civilizational forks. The opportunities created by modern technology create the prospect of a transition from economics to noonomy, which means abandoning economic rationality, leading to an unrestrained pursuit of increasing production and consumption. The place of economic rationality is occupied by rationality based on the criteria of knowledge and culture. However, such a transition from economics to noonomy should be based on a change in the totality of social relations, and noonomy can be strengthened only within the framework of an integral system of the noosociety. The very nature of public relations and public relations of people, the nature of human socialization and socialization of society will orient social development to these new criteria. The ideological orientation of such a reformatting of society can be the ideology of solidarity, which grows out of the emerging opportunities to overcome the discord of socio-economic interests of people based on the struggle for material resources.
Noonomy as the forming linchpin for the new technological and world economic order
Authors:   Collegium of the Eurasian Economic Commission, Glaziev S.Yu.
Published: March 2022

The author has repeatedly addressed international military and political tensions in his works and linked them to changes in technological and world economic patterns. The author used his own methodological apparatus to analyse the new technological, managerial and social structures, including the author’s terms of such as technological and world economic structures. Considering the global crisis as a process of change in technological and world economic structures, the author concludes that a new cycle of capital accumulation has emerged in the Asian century. The new world economic order, according to the author, is based on the principles of non-discrimination, which enables developing countries to establish equitable and mutually beneficial relations with other states. In identifying three scenarios for the transition to Noonomy, the author assumes that the option of forming a world government is the least likely to occur.
The evolution of the content of human activity and the change in the structure of the economy
Authors:   Lomonosov Moscow State University, Kolganov A.I.
Published: March 2022

The article raises the question of how the mutual influence of shifts in the structure of the economy and changes in the content of human activity in production occurs. This problem is only partially addressed in the available sociological, economic and philosophical studies. The content of labor and the structure of the economy are most often considered in isolation, and their mutual influence is studied only from the point of view of investments in “human capital” necessary for the functioning and development of modern technologies in production. However, the technological shifts taking place in recent decades have led to a significant expansion of the range of human activities, which necessarily have creative functions. This dependence was distorted in the concept of the “creative class”, since it included employed people involved in activities that have an ambiguous and sometimes opposite impact on the evolution of the structure of the economy. A significant part of the creative potential is used to extract profit by producing simulated goods, manipulating the market and consumer preferences. Particular attention is paid to the situation in Russia, where the presence of significant human potential is accompanied by its gradual degradation, and shifts in the economic structure determine the low level of demand for this potential. This situation is in contrast with the period of the 20s – 30s. The twentieth century, when the USSR implemented a strategy of technological modernization, based, among other things, on the program of training qualified personnel and the development of scientific research. The transition to the widespread use of creative functions in labor activity will require both a progressive change in the technological structure of the economy and a change in the criteria of production activity by moving away from economic rationality in favor of the criteria of reason and culture. Such a transition will require a corresponding change in public relations in favor of relations of cooperation and solidarity and deep shifts in the institutional structure.

Published: March 2022

Abdominal plastic is one of the most common operations in the field of plastic surgery. The main goal of abdominal plastic is to improve the body contours in the area of the anterior abdominal wall, by excising excessive skin and fat tissues, suturing diastasis of the direct abdominal muscles. Although abdominal plastic is considered a safe surgery with a high level of positive outcomes, there are still various kinds of complications, the treatment of which requires the use of modern methods. The work is based on the analysis of literature data on abdominal plastic and analysis of the postoperative period of 172 patients operated on in plastic surgery clinics in Krasnoyarsk from 2017 to 2020. Statistical data on abdominal plastic prevalence among aesthetic procedures were analyzed. Based on the identified data, it is shown that various types of abdominal plastic are quite in demand, which dictates the need to study possible complications after surgery, and modern methods of treating complications. The article analyzes common types of complica­tions after abdominal plastics and describes the algorithms for treating these complications. A comparative analysis of the incidence of complications in plastic surgery clinics in Krasnoyarsk was carried out with data from European plastic surgery clinics. Complications after abdominal plastic vary in severity and in the effect they have on aesthetic outcomes. Most complications can be treated in an outpatient setting, following modern standards, with satisfactory results.

Materials and methods: this review article analyzes the data of Russian and foreign literature on the etiology, pathogenesis, diagnosis and treatment of slipped capital femoral epiphysis.  

Results: in view of the frequent distribution in the population, high risks of disability in pediatric patients, the issue of treatment of slipped capital femoral epiphysis remains very relevant. Many methods of surgical treatment have been proposed depending on the stage of the disease, however, they have their own advantages and disadvantages.  

Conclusions: Conservative treatment in the long term did not show good results, generally accepted, according to most sources of literature, surgical treatment is considered. The gold standard in the surgical treatment of the disease does not exist today, and the methods and tactics of treatment are being improved.
Toward a Better Understanding of Cosmic Chronometers: A New Measurement of H(z) at z ∼ 0.7
Authors: Borghi Nicola , Moresco Michele , Cimatti Andrea
Published: March 2022

We analyze the stellar ages obtained from a combination of Lick indices in Borghi et al. for 140 massive and passive galaxies selected in the LEGA-C survey at 0.6 < z < 0.9. From their median age–redshift relation, we derive a new direct measurement of H(z) without any cosmological model assumption using the cosmic chronometer approach. We thoroughly study the main systematics involved in this analysis: the choice of the Lick indices combination, the binning method, the assumed stellar population model, and the adopted star formation history; these effects are included in the total error budget. We obtain H(z = 0.75) = 98.8 ± 33.6 km s−1 Mpc−1. In parallel, we also propose a simple framework based on a cosmological model to describe the age–redshift relations in the context of galaxy downsizing. This allows us to derive constraints on the Hubble constant H
0 and the typical galaxy formation time. This new H(z) measurement, whose accuracy is currently limited by the scarcity of the sample analyzed, paves the road for the joint study of the stellar populations of individual passive galaxies and the expansion history of the universe in light of future spectroscopic surveys.
Low-resolution Optical Spectroscopy of Recently Discovered Accreting-only Symbiotic Star THA 15–31
Authors: Merc Jaroslav , Charbonnel Stéphane , Garde Olivier , Dû Pascal Le , Mulato Lionel , Petit Thomas , Gális Rudolf
Published: March 2022

Recently, the discovery and characterization of a new accreting-only symbiotic star THA 15–31 was presented. Motivated by the suggestion that the optical spectrum of the star might show the emission lines with higher ionization potential in comparison with previously studied epochs, we have obtained a low-resolution spectrum of this target. The spectrum does not reveal the presence of suggested He ii emission lines. Moreover, the near-UV excess seems to be even less prominent now in comparison with the previous observations, suggesting a decrease in mass transfer and accretion rate. The search for He ii emission lines should be repeated when the accretion rate is higher.
Gravitational Redshift for Wide Binaries in Gaia eDR3
Authors: Loeb Abraham
Published: March 2022

The Doppler effect is commonly used to infer the velocity difference between stars based on the relative shifts in the rest-frame wavelengths of their spectral features. In wide binaries, the difference in gravitational redshift from the surfaces of the constituent stars with distinct compactness dominates at separations ≳10−2 pc. I suggest that this effect became apparent for wide pairs in the Gaia eDR3 catalog but was incorrectly interpreted as a possible modification of Newtonian gravity in the internal kinematics of very wide binaries.
The Equilibrium Temperature of Planets on Eccentric Orbits: Time Scales and Averages
Authors: Quirrenbach Andreas
Published: March 2022

From estimates of the near-surface heat capacity of planets it is shown that the thermal timescale is larger than the orbital period in the presence of a global ocean that is well-mixed to a depth of 100 m, or of an atmosphere with a pressure of several tens of bars. As a consequence, the temperature fluctuations of such planets on eccentric orbits are damped. The average temperature should be calculated by taking the temporal mean of the irradiation over an orbit, which increases with

. This conclusion is independent of the orbital distance and valid for Sun-like stars; the damping is even stronger for low-mass main sequence hosts.
Optimal positive lymph node ratio showing the benefit of postoperative radiotherapy in pathologic N2 non-small cell lung cancer: an exploratory study using the Surveillance, Epidemiology, and End Results data
Authors: Lee Shiho , Noh O Kyu
Published: March 2022

Purpose: This study aimed to identify the clinical parameters having the beneficial effect of postoperative radiotherapy (PORT) in pathologic N2 (pN2) non-small cell lung cancer (NSCLC) using the Surveillance, Epidemiology, and End Results (SEER) data. Materials and methods: Among non-metastatic NSCLC patients in the SEER data, we included patients who diagnosed after 2002, who confirmed as pN2 after lobectomy or pneumonectomy, and who coded as underwent PORT or observation. Patients who survived less than 4 months of diagnosis were excluded in consideration of the perioperative mortality. After performing propensity score matching (PSM) on the selected patients, we compared PORT group with surgery alone group. We also performed exploratory subgroup analysis to find patients who could benefit from PORT.Results: Among the selected 4,456 patients, 1,729 patients received PORT, and 2,727 patients did not. There was no survival benefit of PORT in all patients with pN2 disease (hazard ratio [HR] = 1.03, p = 0.5). In subgroup analyses, the patients with a positive lymph node (LN) ratio of 60%–80% showed the significant benefit of PORT (HR = 0.71, p = 0.002).Conclusion: PORT did not show the significant survival benefit in patients with pN2 disease after correcting the confoundedness in the SEER data. However, a specific range of LN ratios can be a potential indicator maximizing the survival benefit of PORT.

New space medicine instruments used on the Russian sector of the international space station are considered. Since 2000, four new secondary power systems for space instruments have been developed at the Institute of Space Research and Technology – Bulgarian Academy of Sciences. They are applicable in both space physics and space medicine.
Identifying Batch Problems in Aircraft Field Reliability Analysis
Authors: Kolev Kolyo , Tanev Angel
Published: March 2022

In practice, a very important task is to monitor the field reliability of aircraft systems, especially the ones related to aviation safety, and to take relevant actions to prevent from potential consequences. Zooming in that task, one can state that a very important step in that analysis is to identify batch problems where the failure mode only affects a subset of the fleet. The Weibull distribution typically provides the best fit of life data obtained either from test or from field. This is due in part to the broad range of distribution shapes that are included in the Weibull family. As well as, there are many other distributions which are included in the Weibull distribution’s family either exactly or approximately- for example, the normal, the exponential, the Rayleigh, and sometimes the Poisson and the Binomial. This paper presents a practical approach for those aviation professionals dealing with monitoring and analyzing the aircraft field reliability.
Challenges in International Research on Celestial Bodies. The Prospects of the Bulgarian Space Policy
Authors: Milanov Aleksandar
Published: March 2022

The article explores the present political challenges in international research and exploration of states and private actors of celestial bodies. The lack of shared vision of what type of space activities should be planned and the principles of creating research facilities and scientific missions on the Moon and other celestial bodies is causing uncertainty in future space missions and increases the possibility for a military conflict. The political alliances that exclude specific states will increase the risk of a generation of unnecessary space debris and space waste on celestial bodies. This dangerous outcome could be prevented by agreeing on a shared vision of exploitation and exploration of celestial bodies that preserve the outer space environment and adopting comprehensive guidelines for space activities accepted by the leading space-faring nations.

Three new Distoseptispora (Distoseptisporaceae) species, D. meilingensis, D. yongxiuensis and D. yunjushanensis from submerged decaying bamboo culms in Jiangxi Province, China, were discovered, based on phylogenetic analyses and morphological characters. The combined data of ITS-LSU-SSU-Tef1 sequences were used to infer the phylogenetic relationship between D. meilingensis, D. yongxiuensis, D. yunjushanensis and related species. Both molecular analyses and morphological data supported D. meilingensis, D. yongxiuensis and D. yunjushanensis as three independent taxa.

Entre septembre 2004 et juin 2011, une étude portant sur les liens mère-enfant dans un contexte de déficience visuelle maternelle a été réalisée dans le cadre du Projet PILE mené à l’hôpital Necker-Enfants malades et en lien avec un service d’aide à la parentalité des personnes handicapées. Un suivi longitudinal et prospectif de douze dyades a été effectué dès les 3 mois de l’enfant jusqu’à l’âge de 4 ans. Les résultats montrent que chaque partenaire de la dyade tente de s’ajuster à la singularité de l’autre.
Trouble de l’attachement, trouble du neurodéveloppement ?

Published: March 2022

Après une revue de la littérature concernant l’attachement chez l’enfant sourd, nous présentons une réflexion sur l’apport de ce modèle théorique pour mieux comprendre la clinique hétérogène et singulière de la surdité infantile avec comorbidités. À partir de deux situations issues de cette clinique, nous interrogeons l’intrication des troubles d’attachement et des troubles du neurodéveloppement dans cette population. Partant d’un référentiel théorique psychanalytique, cette étude de la théorie de l’attachement a permis un renouvellement de notre questionnement clinique.
L’enfant et l’adolescent polyhandicapés, sa famille et le processus d’attachement
Authors: Fernandez Fidalgo David
Published: March 2022

Par leurs travaux, Bowlby et ses successeurs ont mis en évidence l’impact de la séparation et de la perte sur les enfants. La situation de handicap, dans sa complexité, peut mettre en péril le processus d’attachement dans les familles, en raison des traumatismes vécus qui impactent le fondement même de la famille, en particulier le sentiment de compétence parental. En reprenant des concepts de la théorie de l’attachement et les apports d’autres auteurs qui s’en sont inspirés, nous décrivons à partir d’exemples concrets comment les familles développent un style d’attachement dominant et l’impact qu’il peut avoir sur les membres de la famille et in fine sur l’enfant en situation de polyhandicap. Cette attention aux processus d’attachement n’est pas à maintenir seulement au début de la vie, mais tout au long du développement de l’enfant polyhandicapé.
Quand le bien-être au travail rencontre la performance : une analyse des représentations sociales d’assistants sociaux
Authors: Bernard Nathalie , Abord de Chatillon Emmanuel
Published: March 2022

Le propos de notre contribution est de clarifier la compréhension du lien entre bien-être au travail et performance. Cinquante-cinq entretiens ont été réalisés auprès de salariés d’une structure spécialisée dans le service social du travail, et proposant à ce titre des actions d’accompagnement social pour les salariés d’entreprises privées et d’organismes publics. Il ressort de l’analyse des représentations sociales que les deux concepts « bien-être au travail » et « performance » présentent une dualité complémentaire combinée à une imbrication ou une interdépendance des deux concepts. Il a également pu être mis en avant que la satisfaction était une dimension commune au bien-être au travail et à la performance.
L’habitat participatif, espace de souveraineté commune ou communauté sélective de l’économie solidaire ?
Authors: Vignet Julien
Published: March 2022

En France, l’habitat participatif visant à vivre autrement reste peu développé. Les projets font face à une complexité juridique et à un manque de reconnaissance. L’initiative de militants associatifs de l’agglomération caennaise, regroupés au sein de la coopérative d’habitants des Z’écobâtisseurs depuis 2011, l’illustre bien. Treize familles associées décident de construire des maisons individuelles groupées, tout en aménageant des espaces communs, souhaitant ainsi favoriser la coopération. Précurseur en France, l’initiative s’inscrit dans l’économie solidaire et intègre les préoccupations environnementales. Elle est toutefois aussi un groupe sélectif, tant les trajectoires sociales, politiques et culturelles des habitants concernés sont homogènes. On note par ailleurs un repli des habitants sur la sphère privée et un délaissement des espaces communs, alors que ces derniers expriment la recherche d’une autre manière d’habiter.
L’entreprise sociale au Cambodge : typologie et institutionnalisation
Authors: Khieng Sothy , Lyne Isaac , Toucas-Truyen Patricia
Published: March 2022

Cet article présente différentes notions d’entreprises sociales (ES) en soulignant le besoin aigu de renforcement des capacités dans la sphère politique où, jusqu’à présent, seules la microfinance et les coopératives agricoles ont reçu un soutien législatif de la part du gouvernement royal du Cambodge. Les problèmes essentiels au Cambodge sont la densité des organisations non gouvernementales dont sont issues la majorité des ES et les modifications des modalités de l’aide internationale. Les variables principales pour distinguer les ES au Cambodge prennent en compte leur enregistrement effectif comme entreprise et leur gouvernance. L’article fait écho à un travail sur la typologie des ES en Asie de l’Est, qu’il amène à se confronter aux réalités différentes de l’Asie du Sud-Est.
ESS, entreprise sociale et pauvreté : l’exemple des Philippines
Authors: Dacanay Marie Lisa , Mammar El Hadj Sihem
Published: March 2022

Cet article porte sur un certain type d’entreprises sociales ayant émergé aux Philippines dans un contexte marqué par la pauvreté et les inégalités sociales. Il s’agit d’entreprises sociales permettant aux pauvres d’être les principaux acteurs de la création et de la redistribution de la richesse. L’auteure présente les principaux résultats de trois recherches qu’elle a menées entre 2008 et 2015 en collaboration avec l’Institut de l’entrepreneuriat social en Asie, sur ces entreprises dans lesquelles les pauvres sont les principaux intervenants (Social enterprises with the poor as primary stakeholders, SEPPS). Elle distingue deux modèles : le modèle de collaboration qui implique les pauvres comme partenaires transactionnels et le modèle d’autonomisation dans lequel les pauvres ne sont mobilisés qu’en tant que partenaires transformationnels. En tant que réponses aux défaillances de l’Etat et du marché et en tant qu’organisations hybrides engagées dans ce processus de transformation, les SEPPS jouent un double rôle dans la construction d’une économie équitable et plurielle aux Philippines.
Les entreprises autogérées au Portugal, de la révolution des Œillets à l’économie sociale
Authors: Marie Pierre
Published: March 2022

La révolution des Oeillets, en avril 1974, a constitué une rupture dans l’histoire contemporaine portugaise. La chute du régime autoritaire de Salazar a permis une transformation en profondeur du pays. Des expériences d’autogestion sont alors apparues dans la sphère économique afin de préserver les emplois. Portés par ce contexte favorable, les travailleurs ont organisé la reprise de la production. Avec la fin du processus révolutionnaire, en 1976, les entreprises autogérées se sont trouvées isolées, malgré la protection constitutionnelle qui les caractérise. L’élaboration récente de l’économie sociale au Portugal a néanmoins conduit à une reprise de la notion d’autogestion.
Mieux caractériser les PTCE face à un processus rapide d’institutionnalisation
Authors: Fraisse Laurent
Published: March 2022

Issus d’une démarche collaborative et expérimentale entre acteurs, réseaux et chercheurs de l’ESS, les pôles territoriaux de coopération économique (PTCE) ont connu un processus rapide d’institutionnalisation. Le retour sur les étapes clés de cette histoire et le repérage des raisons de cette mise à l’agenda politique permettent d’éclairer les enjeux relatifs à la qualification en tant que PTCE de tel ou tel regroupement coopératif multiacteurs. Dans ce contexte, une caractérisation empirique de la morphologie, des modalités de coopération et de la gouvernance de plusieurs PTCE est nécessaire pour souligner les potentiels et la diversité de ces expérimentations en mettant à distance des cadrages juridiques et politiques parfois trop normatifs ou restrictifs.
Quelle place pour les PTCE dans une perspective d’économie verte ?
Authors: Lecat Christopher , Lerouvillois Philippe , Nieddu Martino
Published: March 2022

L’étude de deux pôles territoriaux de coopération économique (PTCE) à vocation industrielle, inscrits dans des projets d’écologie industrielle et territoriale (Ardaines et Fe2i), nous permet de questionner l’inscription de l’ESS à la fois dans les secteurs industriels et dans le champ du développement durable. Ancré dans une approche en termes de patrimoines productifs collectifs, ce travail vise à montrer que la forme PTCE est une forme d’organisation de la construction des apprentissages adaptée à l’émergence des projets de création d’activités économiques et de développement territorial par la constitution de ressources collectives.
L’apport des banques populaires au progrès économique et social en Bulgarie entre les deux guerres (1919-1938)
Authors: Marinova Tsvetelina , Nenovsky Nikolay , Toucas-Truyen Patricia
Published: March 2022

Issue d’une longue tradition mutualiste et solidaire de la population, la finance sociale en Bulgarie a émergé dans des conditions politiques et économiques particulières. Le crédit coopératif a joué un rôle clé dans l’établissement du système financier et économique de la Bulgarie entre les deux guerres (1919-1938). L’objectif de cet article est d’apporter un éclairage sur l’essor des banques populaires et leur impact sur l’économie dans la période de l’entre-deux-guerres. Au début des années 1930, les banques populaires étaient devenues la forme coopérative la plus développée en Bulgarie, particulièrement dans les villes.
Les mutuelles de santé au Sénégal face aux difficultés de coordination de leurs acteurs
Authors: Alenda-Demoutiez Juliette
Published: March 2022

Au Sénégal, seuls les salariés et les fonctionnaires ont droit à une couverture maladie institutionnalisée. Pour l’étendre à l’ensemble de la population, le système de santé se base aujourd’hui sur les mutuelles de santé. Les interlocuteurs des mutuelles se multiplient en même temps que les difficultés de coordination. L’auteure avance l’hypothèse que ces difficultés proviennent de la hiérarchie existant entre les acteurs et de leurs diverses conceptions du système de santé. La majorité des études se focalise sur les difficultés techniques des mutuelles, mais peu sur les difficultés institutionnelles. Pour combler cette lacune, l’auteure a mené au Sénégal de 2013 à 2015 une étude de terrain, ce qui a permis de faire émerger une convention mutualiste propre au Sénégal et fondée sur deux référentiels, l’un assurantiel, l’autre porté par les valeurs de l’ESS.
La société anonyme à participation ouvrière (Sapo) : entre centenaire et nouvel horizon
Authors: Daviau Roger , Lulek Michel
Published: March 2022

Cet article étudie la Société anonyme à participation ouvrière (Sapo) au moment où celle-ci fête son centenaire, et alors que la loi sur l’ESS de 2014 n’a pas promu ce statut d’entreprise participative. Les auteurs étudient dans un premier temps la Sapo comme objet juridique, notamment en la comparant à la Société coopérative de production (Scop), puis s’intéressent au processus historique qui a conduit à la création et à l’évolution de cette formule juridique à partir de 1917. Enfin, au travers de l’étude des deux Sapo Ambiance Bois et Nova Construction, l’intérêt très actuel des Sapo est souligné dans deux situations. D’abord dans le cadre d’une reprise d’entreprise par ses salariés, ensuite pour faciliter une pratique autogestionnaire au long cours.
