Published: January 2023

A control system in the form of an Automatic Transfer Switch (ATS) is needed when a blackout occurs from the PLN that will be transferred to the generator. The research problem was how to save costs for making ATS that can run efficiently. The purpose of this study was to find out how to save costs for making ATS that can run well and efficient. The method used was Research and Development. The Research and Development stages included: collecting data, designing, and testing. To save costs for making ATS, the researchers used the Timer Delay Relay (TDR), as using TDR reduces the cost of making tools because the component prices are relatively affordable. The way the ATS system works is when the PLN electricity is on, the battery will be charged by the battery charger, and when the PLN electricity goes out, the inverter will get a voltage supply from the battery, that was originally 12V will be changed to 220V. The TDR makes it easier to determine the appropriate time when the voltage is stable. Based on the experiment, the time when the voltage is stable is 6 seconds.

Authors: Ally Akbar Salim  , Emilia Hesti  , Lindawati
Published: January 2023

This study aimed to produce a flood alert system that can monitor water-levels in watersheds based on the Internet-of-Things (IoT), using the NodeMCU ESP8266 as a microcontroller and connecting internet connections. The main hardware used was a probe sensor as a water-level detector, an LED as a water level indicator, an LCD displaying the water level status, and a nodeMCU ESP8266 as a processor for the probe sensor detection results and sending information on the water-level status to the Telegram on Android. The status consisted of a safe level when the water level was at 1.5 m, an alert status was at 2 m, and a hazard status was at 3 m. When the water surface touched the probe sensor, nodeMCU ESP8266 read and processed the detection results. Then the status information was sent to Telegram and displayed on the LCD.

At present just about 30% of the waste plastic collected is efficiently recycled, while the rest is incinerated, disposed in landfills, or can end up in compost and be released in the environment, inducing a very negative effect on safety and health of flora and fauna. Sustainable management of hardly recyclable plastic waste generated by light weight single use packaging and agricultural films can be improved by applying biotechnological approaches, combining microorganisms, new enzymes, earthworms, and insects to work collaboratively, not only to promote the degradation of these plastics but also to obtain, by-products of the biodegradation process to be valorized as fertilizers, functional polysaccharides, etc. In order to develop a feasible process, mapping and characterization of the most diffused agri-food waste plastic were conducted isolating the main types of plastic involved. Plastic waste in agriculture is mainly constituted by polyethylene (PE) both linear low density (LLDPE) and high density (HDPE), polypropylene (PP) and polystyrene (PS), whereas in food packaging polyethylene is still present together with a large presence of polypropylene, polystyrene and polyethylene terephthalate (PET). Combining plastic presence and availability of organisms for their degradability, representative samples of plastics (PE, PET, PS) were selected for analysis of deterioration and potential subsequent biodegradation by enzymes and organisms. To monitor the plastic degradability by enzymes, and larvae, methods for the plastic analysis were set, outlining some differences in virgin and post consumer plastic in particular after use in agriculture, assessing the possibility to monitor the degradability of plastic with time and different treatments, in particular, some evidence of polyethylene degradability from larvae of Tenebrio molitor was observed.

Published: January 2023

The article focuses on two collectors – Nélie Jacquemart André, who was French, and Isabella Stewart Gardner, who was American. Both ladies created fascinating collections at the turn of the 19th and 20th centuries including a wide range of art objects from different periods. The core of these private collections was the art of the Italian Renaissance. The study deals with the questions of the formation of these sets of Renaissance works of art, methods of acquisitions, the nature of collection objects, and especially installation principles applied in two museum collections that are now publicly accessible – the Musée Jacquemart-André in Paris and the Isabella Stewart Gardner Museum in Boston.
Poprvé na scéně. K premiéře Dvořákovy Rusalky v Národním divadle v roce 1901
Authors: Vejvodová Veronika
Published: January 2023

The study brings a new perspective and unknown facts about the world premiere of Dvořák’s most famous opera Rusalka, which was first performed on 31 March 1901 at the National Theatre in Prague. Through previously unheeded sources and literature, the text provides a detailed description of the circumstances of the premiere and the dramatic situation in the management of the National Theatre, which underwent a major change in 1900. The premiere of Rusalka was given exceptional care by the theatre: the composer attended rehearsals of the orchestra led by the newly elected head of the opera, Karel Kovařovic, who had a reputation as an excellent conductor. Great attention was also paid to the costume and stage design. However, the premiere was jeopardised on the day of its performance by the main character of the prince, the European renowned tenor Karel Burian, who cancelled the performance on the same day. He was replaced by Bohumil Pták, who, according to his recollection of these events, had studied the role with Burian. The issue of the premiere of Rusalka also opens up the topic of the relationship between Kovařovic and Dvořák, two prominent figures of Czech opera at the end of the 19th century, which is discussed against the background of the later so-called struggle for Dvořák (1913).

Aim: To investigate the effect of of adding oophorectomy on patients who underwent abdominal hysterectomy in the perimenopausal period on menopause, sexual function and mental status. Materials and Methods: The study was designed prospectively. Women who underwent total abdominal hysterectomy and bilateral salpingectomy (TAH+BS) and total abdominal hysterectomy and bilateral salpingo-ophorectomy (TAH+BSO) in the perimenopausal period for benign indications were included in the study. Three months after surgery, menopausal symptoms (such as vasomotor symptoms, vaginal dryness and/or dyspareunia, memory and sleep problems) were investigated. Beck Anxiety Inventory (BAI) scores were investigated one day before the operation and three months after the operation. Results: 51 patients with TAH+BS and 55 patients with TAH+BSO included in study. Vasomotor symptoms and postoperative BAI scores were significantly higher in the oophorectomy group (p<0.001 and p=0.009, respectively). Vaginal dryness and/or dyspareunia, which adversely affect sexual function, were significantly higher in the oophorectomy group (p=0.005). Memory and sleep problems were higher in the oophorectomy group (p=0.009 and p<0.001, respectively). Postoperative BAI scores were found to be correlated with postmenopausal symptoms (vasomotor symptoms, vaginal dryness and/or dyspareunia, memory problems, sleeping disorders) in the TAH+BSO group. Conclusion: Vasomotor symptoms, vaginal dryness and/or dyspareunia, memory and sleeping problems, and anxiety levels were significantly higher in patients who underwent bilateral salpingo-ophorectomy with hysterectomy compared to patients who underwent only hysterectomy and bilateral salpingectomy. It seems useful to inform the patients who are planned for the operation regarding these effects before the decision of oophorectomy.
The Effects of Capitalized R&D Expenditure on Audit Efforts: Focusing on Audit Hours by Rank and Auditor Size
Authors:   Academic Society of Global Business Administration, Kim Hyoeun
Published: January 2023

This study examines whether capitalized research and development(R&D) expenditure has an effect on the audit effort of external auditors using the audit hours by rank, and whether this effect differs by auditor size. R&D expenditure is reported as an asset if certain criteria are met, otherwise it is reported as an expense. However, there is a possibility of earnings management as discretionary judgment could be involved in the practical application of accounting standards. Accordingly, if capitalized R&D expenditure is high, it is expected that the auditor will consider it as an audit risk and increase the audit effort. Compared to non-Big4 auditors, Big4 auditors will have a clearer response to capitalized R&D expenditure because Big4 auditors have relatively large losses in the event of audit failure and have a large number of manpower.
The non-financial listed companies that can be collected from the TS2000 and KISVALUE are analyzed. The period of analysis is from 2014 to 2017, and the data set contains 5,884 firm-years.
As a result of empirical analysis, capitalized R&D expenditure is positively associated with total audit hours, partner audit hours, and registered CPA audit hours. And this effect is evident in the sample of Big4 auditors. These results suggest that the auditors judge capitalized R&D expenditure as an audit risk factor and respond to it, and this response is prominent in the Big 4 auditors.
This paper has contributions in that it expands the previous research by analyzing the effect of R&D expenditure on auditors' audit hours by rank. In addition, through separate analyzes of the Big4 auditor sample and the non-Big4 auditor sample, the evidence is provided that the effect of R&D expenditure on audit efforts varies depending on the auditor size.
Development and systematization of the operating model of the NCS-based youth employment academy
Authors:   Academic Society of Global Business Administration, Park Se Hun , Kim So Hyoung , Jeong Yeon Sil , Lee Jae Sung
Published: January 2023

In the era of the 4th industrial revolution, the concept of the workplace faded as the employment type was hired from regular workers to contract workers, and the job market was transformed into a job market where job skills were emphasized due to frequent turnover. In addition, the reality is that college graduates and prospective graduates are suffering from difficulties in finding a job due to social advancement and job mismatch. In this situation, the youth employment academy curriculum, which nurtures young talents required by industry, was helpful in many ways to provide an educational model. However, as the youth employment academy project was carried out, problems arose in the curriculum, operation process, and student recruitment. Therefore, this study aims to identify problems and improve the curriculum of the youth employment academy by conducting in-depth interviews with professors and staff in charge, as well as a learning satisfaction survey for students. Furthermore, it is intended to present examples of systematization and modularization of the NCS-based employment curriculum through self-directed learning satisfaction survey. Through this study, it is intended to contribute to the expansion and efficiency increase of the employment curriculum for humanities students, which will be newly designed in the future.
Employee Adjustment Costs and Asymmetric Cost Behavior
Authors:   Academic Society of Global Business Administration, Kim Yong Mi , Kim Jinbae
Published: January 2023

The managerial accounting literature suggests that adjustment costs lead to asymmetric cost behavior. Previous studies show that labor adjustment costs are the significant factor that drives asymmetric cost behavior. However, empirical proxies for labor adjustments costs have several limitations. This study suggests that CEO-to-worker pay disparity and the labor share as a new proxy for labor adjustment costs and substantiates that labor adjustment costs play a significant role in determining asymmetric cost behavior. Our proxies for adjustment costs represent the effectiveness of labor cost management and labor productivity. Prior studies suggest that large CEO-to-worker pay disparity indicates effective labor cost management. We find that lower CEO-to-worker pay disparity and higher labor income share are associated with greater cost stickiness. In additional tests, we find that the effect of adjustment costs is more significant for firms disclosing ESG grades and firms with higher ESG grades.
A Study on the Countermeasures for the Establishment of XBRL(eXtensible Business Reporting Language)
Authors:   Academic Society of Global Business Administration, Jung Woo June , Yoon Jae Won , Shim Jun Yong
Published: January 2023

This study aims to provide a reasonable basis for the feasibility of introducing XBRL based on a review of prior studies on the usefulness of XBRL and a correlation between IFRS and XBRL disclosures to facilitate financial statements disclosure using the XBRL. In addition, by comparing the current status of the introduction of XBRL in major countries, an applicable improvement plan in Korea is derived. Prior studies on the usefulness of XBRL argue that financial statement information structured by the introduction of XBRL has a low possibility of error and earnings management, and high convenience of analysis. As a result of reviewing the relationship between IFRS and XBRL disclosures, the XBRL provide the content as it is in a structured form, rather than by changing the content of existing financial statements. And just as XBRL taxonomies are developed and updated in due process based on the principle-based IFRS by IASB, it is expected that the comparability between countries will be significantly improved if authoritative bodies update taxonomies appropriately reflect their disclosure practices. And it was found that both the United States and the EU are introducing XBRL more strongly than Korea. The U.S. requires all listed companies and some other companies to apply Inline XBRL to prepare financial statements and notes in 10-Q and 10-K reports. The EU requires all listed companies to apply Inline XBRL to prepare consolidated financial statements in annual reports. The U.S. and the EU are led by supervisory agencies over the underlying laws, but in Korea, it is judged that the introduction of XBRL is not smooth. Therefore, in order to revitalize the introduction of XBRL in Korea, it is necessary to prepare a clear legal basis for the introduction of XBRL, and to create an stakeholder-centered XBRL ecosystem based on this.

Very young (t ≲ 10 Myr) stars possess strong magnetic fields that channel ionized gas from the interiors of their circumstellar disks to the surface of the star. Upon impacting the stellar surface, the shocked gas recombines and emits hydrogen spectral lines. To characterize the density and temperature of the gas within these accretion streams, we measure equivalent widths of Brackett (Br) 11–20 emission lines detected in 1101 APOGEE spectra of 326 likely pre-main-sequence accretors. For sources with multiple observations, we measure median epoch-to-epoch line strength variations of 10% in Br11 and 20% in Br20. We also fit the measured line ratios to predictions of radiative transfer models by Kwan & Fischer. We find characteristic best-fit electron densities of n

e
= 1011–1012 cm−3, and excitation temperatures that are inversely correlated with electron density (from T ∼ 5000 K for n

e
∼ 1012 cm−3 to T ∼ 12,500 K at n

e
∼ 1011 cm−3). These physical parameters are in good agreement with predictions from modeling of accretion streams that account for the hydrodynamics and radiative transfer within the accretion stream. We also present a supplementary catalog of line measurements from 9733 spectra of 4255 Brackett emission-line sources in the APOGEE Data Release 17 data set.

We report a candidate of a low-luminosity active galactic nucleus (AGN) at z = 5 that was selected from the first near-infrared images of the JWST CEERS project. This source, named CEERS-AGN-z5-1 at absolute 1450 Å magnitude M
1450 = −19.5 ± 0.3, was found via a visual selection of compact sources from a catalog of Lyman break galaxies at z > 4, taking advantage of the superb spatial resolution of the JWST/NIRCam images. The 20 photometric data available from CFHT, Hubble Space Telescope, Spitzer, and JWST suggest that the continuum shape of this source is reminiscent of that for an unobscured AGN, and there is a clear color excess in the filters where the redshifted Hβ+[O iii] and Hα are covered. The estimated line luminosity is L
Hβ+[O III] = 1043.0 erg s−1 and L
Hα
= 1042.9 erg s−1 with the corresponding rest-frame equivalent width EWHβ+[O III] = 1100 Å and EWHα
= 1600 Å, respectively. Our spectral energy distribution fitting analysis favors the scenario that this object is either a strong broad-line emitter or even a super-Eddington accreting black hole (BH), although a possibility of an extremely young galaxy with moderate dust attenuation is not completely ruled out. The bolometric luminosity, L
bol = 2.5 ± 0.3 × 1044 erg s−1, is consistent with those of z < 0.35 broad-line AGNs with M
BH ∼ 106
M
⊙ accreting at the Eddington limit. This new AGN population in the first 1.1 billion years of the universe may close the gap between the observed BH mass range at high redshift and that of BH seeds. Spectroscopic confirmation is awaited to secure the redshift and its AGN nature.

Mergers are thought to be a fundamental channel for galaxy growth, perturbing the gas dynamics and the magnetic fields (B-fields) in the interstellar medium (ISM). However, the mechanisms that amplify and dissipate B-fields during a merger remain unclear. We characterize the morphology of the ordered B-fields in the multiphase ISM of the closest merger of two spiral galaxies, the Antennae galaxies. We compare the inferred B-fields using 154 μm thermal dust and 11 cm radio synchrotron emission polarimetric observations. We find that the 154 μm B-fields are more ordered across the Antennae galaxies than the 11 cm B-fields. The turbulent-to-ordered 154 μm B-field increases at the galaxy cores and star-forming regions. The relic spiral arm has an ordered spiral 154 μm B-field, while the 11 cm B-field is radial. The 154 μm B-field may be dominated by turbulent dynamos with high 12CO(1–0) velocity dispersion driven by star-forming regions, while the 11 cm B-field is cospatial with high H i velocity dispersion driven by galaxy interaction. This result shows the dissociation between the warm gas mainly disturbed by the merger, and the dense gas still following the dynamics of the relic spiral arm. We find a ∼8.9 kpc scale ordered B-field connecting the two galaxies. The base of the tidal tail is cospatial with the H i and 12CO(1–0) emission and has compressed and/or sheared 154 μm and 11 cm B-fields driven by the merger. We suggest that amplified B-fields, with respect to the rest of the system and other spiral galaxies, may be supporting the gas flow between both galaxies and the tidal tail.
The Deformation of an Erupting Magnetic Flux Rope in a Confined Solar Flare

Published: January 2023

Magnetic flux ropes (MFRs), sets of coherently twisted magnetic field lines, are believed as core structures of various solar eruptions. Their evolution plays an important role to understand the physical mechanisms of solar eruptions, and can shed light on adverse space weather near the Earth. However, the erupting MFRs are occasionally prevented by strong overlying magnetic fields, and the MFR evolution during the descending phase in the confined cases is lacking attention. Here, we present the deformation of an erupting MFR accompanied by a confined double-peaked solar flare. The first peak corresponded to the MFR eruption in a standard flare model, and the second peak was closely associated with the flashings of an underlying sheared arcade (SA), the reversal slipping motion of the L-shaped flare ribbon, the falling of the MFR, and the shifting of top of filament threads. All results suggest that the confined MFR eruption involved in two-step magnetic reconnection presenting two distinct episodes of energy release in the flare impulsive phase, and the latter magnetic reconnection between the confined MFR, and the underlying SA caused the deformation of the MFR. It is proposed that an intergrated evolution for confined MFR eruptions can compose of three stages: the eruption, the confinement, and the deformation.
Alboglossiphonia afroalpina sp. nov. and Alboglossiphonia buniana sp. nov. – two new leech species from Africa and revision of the genus Alboglossiphonia Lukin, 1976 in Africa
Authors: Jueg Uwe
Published: January 2023

Two new leech species from Africa are presented. The position of the eyes, the number of crop caeca and the gonopores separated by two annuli indicate that both belong to the genus Alboglossiphonia. Alboglossiphonia afroalpinasp. nov. differs from the other African species in its elongated body shape, the shape and size of the suckers and above all by the unique spotting on the dorsal side, which is not found in any other species of the genus. Alboglossiphonia afroalpinasp. nov. inhabits the alpine zones of the Mt. Kenya and Mt. Elgon massifs and represents the highest record of a leech in Africa to date, approx 4,500 m above sea level. Alboglossiphonia buniana sp. nov. differs from other species of the genus by its completely fused pairs of eyes, the shape and size of the cranial sucker and the head area and a jagged outer margin. The species is only known from Bunia in northeastern Democratic Republic of Congo.

Eleven species of the genus Alboglossiphonia are known from Africa, belonging to different zoogeographical areas. Northwest Africa is home to Alboglossiphonia hyalina (O.F. Müller, 1774) and A. iberica Jueg, 2008 as Palaearctic species. Alboglossiphonia polypompholyx Oosthuizen, Hussein & El-Shimy, 1988, A. disuqi El-Shimy, 1990 and A. levis Gouda, 2010 are restricted to the lower reaches of the Nile in Egypt. Six species exist south of the Sahara: Alboglossiphonia namaquaensis (Augener, 1936), A. disjuncta (Moore, 1939), A. conjugata (Oosthuizen, 1978), A. macrorhyncha (Oosthuizen, 1978) as well as those described here, A. afroalpinasp. nov. and A. bunianasp. nov. The examination of the three syntypes of Alboglossiphonia namaquaensis (Augener, 1936) showed that this species is identical to A. cheili (Oosthuizen 1978) and that the latter must be used as a synonym in future. Historical evidence from the Central Africa Museum in Tervuren (Belgium) from the Sciacchitano Collection and the British Museum of Natural History was examined. The systematic position of Glossiphonia verrucata Sciacchitano, 1939 was also clarified. Almost all species were photographed for the first time, most of them including their holotype. Distribution maps are presented for all species. All African Alboglossiphonia species are compared in terms of their characteristics in tabular form.
Mind the conversion risk: contingent convertible bonds as a transmission channel of systemic risk
Authors: Le Quang Gaëtan
Published: January 2023

L’article développe un modèle théorique dont le but est d’évaluer le risque systémique associé aux obligations contingentes convertibles (coco bonds). Lorsque la conversion de ces dernières repose sur l’évolution d’un prix de marché – dans la perspective de ce que la littérature appelle la discipline de marché indirecte –, les coco bonds peuvent agir comme un canal de transmission du risque systémique. Dans ce cas, une crise auto-réalisatrice se produit en effet du fait de ventes précipitées motivées par l’anticipation d’une conversion des coco bonds. L’article met, par ailleurs, en évidence qu’un accroissement de la précision de l’information publiée par la banque à travers ses états financiers a, la plupart du temps, pour effet de diminuer le risque qu’une telle crise ne se produise. Au contraire, l’accroissement de la précision de l’information privée détenue par les détenteurs de coco bonds a, la plupart du temps, l’effet opposé.
Écriture et recherche : une dynamique de transformation
Authors: Métayer Frédérik
Published: January 2023

Animateur socioculturel de formation 1 , je me suis engagé dans un projet de recherche-action de 2015 à 2019 dans le cadre d’une formation diplômante du travail social (Diplôme d’État d’Ingénierie Sociale). Je souhaite ici témoigner de mon expérience et dire en quoi l’acte d’écriture est un acte de transformation, de la situation observée et de soi-même. Je propose d’aborder l’écriture de la recherche comme lieu de transformation, à travers le questionnement initial qui s’impose à chaque auteur. Transformation qui s’opère aussi à travers le sens et la justesse des mots, lesquels délimitent et donnent vie. Enfin, j’aborderai la question du problème comme éclairage et comme chance.
Acte d’écriture et recherche
Authors: Cadière Joël
Published: January 2023

L’auteur introduit le calculi comme objet premier que l’on trouve à la naissance de l’écriture. Objet symbolique, qui, selon lui, comporte en germe tous les caractères et fondements propres à l’acte d’écriture. Il devient alors, par prolongement, l’opérateur de sa pensée relative à l’acte d’écriture de la recherche-action. Il fait l’hypothèse que l’acte d’écriture aujourd’hui, en particulier l’acte d’écrire une recherche-action, régénère les propriétés fondamentales que l’écriture dans sa genèse a constitué, à savoir : la puissance et l’angoisse, la question du visible et son déchiffrement, la fixité de la mémoire et sa transmission, sa valeur universelle et sa capacité de subjectivation.
Comités d’éthique dans le secteur social et médico-social : une instance de plus ?
Authors: Bonjour Pierre
Published: January 2023

Devant le constat d’une époque-métamorphose de plus en plus complexe, une multitude d’instances éthiques se développent. Quelles en sont les origines, les visées, leurs processus de délibération ? Comment modéliser la multiplicité de leurs tendances ? L’auteur propose des outils permettant aux acteurs sociaux de réfléchir à l’évolution de leur comité d’éthique ou de participer à la création d’une telle instance.
Revue kaléidoscopique du secteur psychiatrique
Authors: Durand Bernard
Published: January 2023

Le secteur est entré officiellement dans l’histoire de l’organisation des soins en psychiatrie avec la circulaire du 15 mars 1960. S’il est devenu une référence quasi-mythique aujourd’hui, il n’en a pas toujours été ainsi, car la sectorisation psychiatrique s’est heurtée à de nombreux obstacles, liée entre autres aux différentes acceptions qu’on lui a données. Ce sont celles-ci que nous passerons en revue jusqu’au secteur rénové dans le territoire de santé mentale d’aujourd’hui.
Un pôle = un secteur
Authors: Cantero Alain
Published: January 2023

La sectorisation psychiatrique a deux missions essentielles : La prise en soin de la personne malade en tant qu’elle est personne de droit et personne sociale, et la participation à la déstigmatisation sociale de la pathologie psychique. On pourrait parler de soutien de l’environnement à l’acceptation de la folie. Dans ces optiques on ne peut se limiter à appliquer des thérapeutiques préconisées par notre dispositif mais il convient d’inventer sans cesse de nouvelles manières de pouvoir rentrer en lien avec les personnes afin de soutenir au mieux leurs démarches personnelles. Le travail au sein d’un secteur de la région parisienne nous est ici présenté.
« Territoires zéro chômeur de longue durée » : Une expérimentation territoriale au prisme de ses proximités
Authors: Retsin Camille
Published: January 2023

L’objectif de cet article est de mettre en lumière, dans le cadre d’une étude exploratoire, la coordination d’une diversité d’acteurs sur un territoire autour de l’expérimentation « Territoires zéro chômeur de longue durée ». Afin d’envisager la coordination de la diversité de parties prenantes impliquées dans ce projet de territoire, nous proposons de mobiliser le cadre théorique des proximités dans un courant d’inspiration institutionnaliste. Nous présentons, dans une démarche qualitative, une étude de cas menée dans le cadre d’une thèse de doctorat sur l’un des dix territoires pionniers de l’expérimentation, le territoire de Jouques. Dans un premier temps, nous analysons la coordination permise par le développement des proximités entre une entreprise à but d’emploi et ses parties prenantes externes sur le territoire. Dans un second temps, nous montrons l’adaptation progressive des comportements organisationnels de l’entreprise à but d’emploi à travers l’évolution des proximités avec ses parties prenantes internes lui permettant de développer ses activités et de ce fait son ancrage au territoire. Ainsi, nous souhaitons mettre en évidence que les proximités permettent la coordination et l’adaptation des comportements organisationnels de l’entreprise à but d’emploi, et réciproquement, nous soulignons que cette expérimentation territoriale est aussi un levier de création de proximités. Nous concluons sur le fait que l’adaptation des comportements organisationnels de l’entreprise à but d’emploi conduit à améliorer sa coordination avec les acteurs du territoire qu’elle contribue à construire dans le cadre de cette nouvelle action publique expérimentale.
Contrôler par et dans l’espace : une approche inter-organisationnelle dans le champ de la santé
Authors: Giordano Florent
Published: January 2023

Peut-on contrôler autrui par l’utilisation des normes spatiales ? Cette contribution propose de répondre à cette question qui permet également d’enrichir les approches traditionnelles de l’école de la proximité en y intégrant la question du pouvoir, une dimension quelque peu laissée de côté selon les tenants de cette approche. Pour ce faire, nous avons mobilisé le concept de dispositif tel que défini par Michel Foucault ainsi qu’une vaste littérature en géographie sociale et critique. Empiriquement, notre recherche repose sur l’étude d’un cas unique : l’action d’une agence régionale de santé. Cette organisation étatique a en effet pour but de piloter le système de santé sur un espace délimité en organisant l’action des opérateurs sur le territoire par différents mécanismes (contractualisation, appels d’offres, allocation de ressources, inspection/contrôle, etc.). Cette contribution amène ainsi à enrichir notre compréhension des mécanismes de contrôle formel en proposant une grammaire de ces mécanismes et en les ancrant empiriquement. Elle souligne également que l’espace doit être envisagé simultanément comme générateur et produit des relations de pouvoir dans le champ organisationnel – un espace sur lequel il faut s’aligner quand on est en situation de dominé, ou le tenter de le contester. Enfin, elle propose une vision dynamique du contrôle inter-organisationnel par l’emploi du concept de dispositif. Utiliser ce concept à l’échelle inter-organisationnelle nous amène toutefois à essentialiser les organisations, saisies comme des boîtes noires. Cela nous empêche ainsi de saisir l’influence des logiques intra-organisationnelles – par exemples les groupes professionnels – sur les relations spatiales. Ce qui pourrait faire l’objet de recherches ultérieures stimulantes.
De l’éclatement des espaces de travail à la création d’un espace-lieu du travail : comment visibiliser l’expérience globale du travail ?
Authors: Volz-Tollet Anne-Sophie
Published: January 2023

L’atomisation des espaces de travail en différents lieux complique la continuité de l’activité et œuvre à la déspatialisation des relations de travail. Un voile épais entoure ce qui se déroule à l’intérieur de ces espaces différenciés et empêche l’organisation fluide du travail. Comment, dans ces conditions, redessiner la spatialisation du travail afin de recréer une action collective organisée ? Pour répondre à cette question, nous proposons la création d’un espace-lieu capable de rendre visible l’expérience globale du travail. Philosophes, géographes, psychologues et gestionnaires étudient depuis plusieurs décennies les notions d’espace et de lieux en tentent d’en dessiner les contours. L’espace comme concept de l’infini, de la liberté, de l’ouverture ; le lieu, espace délimité par une fonction, intime et sécurisant. Pour créer un espace-lieu du travail, nous développons dans cet article une proposition conceptuelle qui articule trois principes de visibilité indispensables permettant aux espaces éclatés d’avoir une existence tangible : visibilité de l’expérience individuelle des espaces par la mise en lumière des gestes, émotions, impressions et atmosphères matérielles ; visibilité des discours rattachés à ces espaces en révélant la pluralité des points de vue, les représentations symboliques et les débats et compromis sous-jacents ; visibilité des relations de pouvoir amarrées à ces espaces, reflets des règles, positions hiérarchiques et fonctionnements des équipes en place. Nous suggérons enfin de repenser l’organisation du travail dans toute sa spatialité afin de renforcer les interdépendances des différents espaces de travail.
Comment la solidarité peut-elle s’inscrire dans l’espace ? Le cas d’un espace de coworking d’entrepreneurs solidaires
Authors: Chabaud Didier , Eynaud Philippe , Raulet-Croset Nathalie
Published: January 2023

La riche littérature sur les espaces de travail collaboratifs montre que l’espace n’est pas neutre et peut avoir des effets structurants sur le comportement organisationnel. Les auteurs s’interrogent sur les principes de l’inscription spatiale d’un des moteurs de l’action collective : la solidarité. Pour cela, l’étude met en avant le processus de co-construction de l’espace par ses usagers et propose une lecture rationnelle (et non morale) des enjeux de solidarité. Cette analyse fondée sur une étude de cas approfondie s’applique à comprendre comment la solidarité peut se mettre en espace. Les résultats de la recherche mettent en lumière la nécessité d’une approche socio-matérielle pour comprendre comment une communauté se réclamant d’un projet solidaire se déploie dans l’espace. Deux modalités de fabrique spatiale de la solidarité sont identifiées. La première est fondée sur une solidarité de communauté homogène s’exprimant sur un espace donné. Elle s’appuie sur une spécialisation des espaces qui oppose l’espace solidaire à d’autres espaces qui peuvent avoir une dimension économique. La deuxième est caractérisée par une solidarité dans un espace ouvert en lien avec une communauté hétérogène. Son avantage est lié à sa capacité à s’inscrire dans des réseaux de solidarité élargis. Elle s’appuie sur des espaces non spécialisés qui permettent un gain en flexibilité dans l’usage. La recherche souligne comment la configuration de l’espace permet de déboucher sur des fabriques différentes de la solidarité, qui peuvent reposer sur la construction de communautés ou bien sur l’articulation entre solidarité mécanique et organique.
