Authors: Wiafe Yaw K. , Asamoah Andrews , Akweongo Patricia , Kumah Augustine
Published: April 2024

Introduction

The prevalence of maternal mortality continues to be a significant health concern across the world. In Ghana, pregnancy-related complications in the previous 5 years account for 12% of all deaths among women 15 to 49 years. More than half of these deaths were avoidable if early assessment had been done. However, assessment of the pooled prevalence of pregnancy-related complications among pregnant women to inform policy is limited. This study sought to determine the factors contributing to pregnancy complications in Ghana.

Methods

Using a systematic sampling technique, a facility-based cross-sectional study was conducted among 415 pregnant women who attended antenatal care (ANC) services at Mamprobi Hospital. Bivariate and multiple logistics regression analyses were conducted to test significant factors determining pregnancy complications. The results of regression analysis are reported in odds ratio. Statistical significance was set at p < 0.05.

Results

The mean age of the participants was 31.6 ± 6.6 years. The incidence of pregnancy complications among the pregnant women was 51.8% (95% CI, 0.47–0.56) The incidence of pregnancy complications among the women was significantly determined by age (adjusted odds ratio [AOR], 6.1; CI, 1.19–30.76), record of pregnancy complication (AOR, 2.5; CI, 1.35–4.49), ANC visit (AOR, 6.1; CI, 2.14–17.70), and family history of pregnancy complication (AOR, 3.6; CI, 1.25–10.40). Other significant factors included a record of abortion (AOR, 7.8; CI, 4.21–14.32), knowledge about obstetric danger signs (AOR, 2.4; CI, 1.21–4.88), and experiencing at least one obstetric danger sign during pregnancy (AOR, 6.6; CI, 3.30–13.29).

Conclusion

The incidence of pregnancy complications was comparatively high among the women who used ANC services at Mamprobi Hospital. Early initiation of ANC services for pregnant women is an essential tool for addressing some of the challenges of early onset of some pregnancy complications, including anemia in pregnancy and preeclampsia. Midwives and other health workers who engage pregnant women should encourage their clients to initiate ANC visits at an early stage.
Universalism v. Relativism: The Human Rights Debate Around Internalization of Global Norm of Anti-FGM in Gorontalo, Indonesia
Authors: Putri Safriska Desna , Sundrijo Dwi Ardhanariswari
Published: April 2024

Researches show how people and government of Southeast Asia tend to promote the relativism of norms, and with that challenge the mainstream narrative that promote the universalism of norms. This partially explains the multiple failures of the regionalisation of many global norms in the region. Female Genital Mutilation (FGM), a term that defines any procedure that harms female genital organs, is a traditional practice that is condemned by many international institutions. Anti-FGM has become one of the most important global norms on health issues, officially adopted as a terminology by WHO in 1991 and become resolution in 2008. Under this circumstances, it is widely known that the practice of female children circumcision is still very commonly found in Gorontalo region in Indonesia. In Gorontalo, this practice involved not only health and rational consideration, but most importantly also is involved tradition and beliefs that have been passed down from generation to generation. It is hence contained a particular cultural meaning, which somehow has become the people’s shared characteristics which further defines the identity of the women of Gorontalo. This strong tradition is, naturally, goes against global believe which consider this custom as a violation on children's and human rights. This local dynamics thus lead us to the contestation between the idea of "universalism" of norms which holds the legitimation of human rights introduced by Liberal thinking,, and the idea of "relativism" which acknowledges the particularity of local tradition, as well as religion, and the rights of the people to practice what they believe as culturally appropriate. This article hence will answer the question, "in what way relativism overcome universalism in the process of internalization of global norms on anti-FGM in Gorontalo, Indonesia?"

Consumer Decision-Making in the Era of Information Overload
Authors: Kaur Harsandaldeep
Published: April 2024

What has emerged as a new paradigm in consumer decision-making in the modern digital age is "information overload," the result of the deluge of data, reviews, ads, and suggestions that customers see at every online interaction. Customers face advantages and disadvantages as a result of information overload. On the one hand, customers are able to do more thorough research on products, services, and brands because to the abundance of information available to them. Decision fatigue, anxiety, and poor decisions can result from consumers being overwhelmed by the sheer abundance of information.

Investigating the Influence of Project Initiation Management on Performance of Mega-dam Projects: Empirical Evidence from Kenya
Authors: Bongei Michael , Sang Paul , Mutuku Morrisson
Published: April 2024

Performance of large projects including mega-dams could be associated with strict adherence to project life cycle (PLC) phases while considering the risks such as displacement of people and natural ecosystem disturbance. Understanding these risks helps project managers and stakeholders make informed decisions thus creating a positive legacy for the project in the long run. The main objective of the research was to determine how project initiation management influences the performance of mega-dam projects in Kenya. This study was guided by positivist research philosophy. A descriptive cross-sectional survey research design was adopted. In this study, the unit of analysis was 18 mega-dam projects launched and completed across Kenya as listed under the Ministry of Water, Sanitation, and Irrigation (MoWSI) while the unit of observation was the respective three officials (project manager, project engineer, geospatial engineer) in the MoWSI. A Census of all mega-dams completed in Kenya was conducted. In addition, the study purposively interviewed 5 key stakeholders including the cabinet secretary, permanent secretary from the MWSI, donor, contractor, and one randomly selected beneficiary from the community with the target mega-dam. This formed a total sample size of 180 respondents. Primary data was collected using the semi-structured questionnaires as well as the Key Informant Interview (KII) guide. Quantitative and qualitative data from multiple sources and perspectives provided a more comprehensive and robust understanding. Pretesting was done by way of pilot testing to ascertain the validity and reliability of the tools. Descriptive and inferential statistics were used to summarize and describe the key characteristics of the data, as well as draw conclusions and make inferences. Correlation findings showed that project initiation management and performance of selected mega-dam projects in Kenya have a strong positive and significant relationship (r= 0.874, p<0.05). In addition, regression findings showed that one-unit rise in project initiation management corresponds to a 0.433 improvement in the performance of these mega-dam projects. Based on the findings, the study concluded that project initiation management positively and significantly influences the performance of selected mega-dam projects in Kenya. This study therefore recommends that project managers should give priority to project initiation management

Published: April 2024

The objective of this study was to characterise Manafwa River floodplain and adjacent soils. Soil samples were collected from 0 - 20 cm depth in fallowed and cultivated Manafwa floodplain soils for laboratory analysis. Treatments included upland (control), floodplains fallowed for a year, floodplains fallowed for over a year, cultivated floodplains within 5 m and 50 m away from the river banks. Each treatment was replicated three times (3 blocks), and samples collected were analysed for K, Na, available P, total N, exchangeable acidity, pH, organic matter, moisture content, sand, silt, and clay. The soil sampling results were subjected to statistical Analysis of Variance (ANOVA) using Randomised Complete Block Design (RCBD), and the difference between treatment means were dictated using F-, student’s t and F-LSD/pairwise comparison tests. There was statistically no significant (p > 0.05) difference among different floodplains and uplands studied. Upland soils posted 71.67% for the highest pH and 0.09%, 0.87%, 9.74 ppm, 2.23 ppm and 7.264% for the lowest available N, organic matter, Phosphorous, Sodium and Moisture Content, respectively. Cultivated floodplain soil posted highest total P at 29.16 ppm and pH at 6.39% while fallowed floodplains lowest pH at 5.34%, highest available N at 0.32%, highest organic matter at 4.02%, highest K at 21.33%, highest Na at 13.93%, highest exchangeable acidity at 2.32 Cmol/Kg, highest clay content at 14.33%, lowest sand composition at 38.00%, highest silt composition at 54.8% and highest Moisture Content of 32.472%. As depicted by soil fertility analysis results, Manafwa River floodplain and adjacent soils have the capacity to accommodate and boost crop production and productivity. Any nutrients lost to leaching could be gained from subsequent fallowing and sustainable soil fertility management, proper drainage, crop rotation, adding organic manure, and cover cropping, among others
Aṣṭāṅga-yoga dan Upaya Peningkatan Kecerdasan Adversitas Manusia

Published: April 2024

Scientists discovered the paradigm of three human intelligences: intellectual, emotional, and spiritual. This paradigm is known as Intelligence Quotient (IQ), Emotional Quotient (EQ), and Spiritual Quotient (SQ). These three are the most important human intelligences. In addition, adversity intelligence, meaning the ability to face challenges and overcome them, is evolving. This qualitative research focuses on texts to reveal the Hindu concept of intelligence. Research and discussion show that some forms of Hindu intelligence are faith (śradhhā), strength, persistence (vīrya), memory (smṛti), and concentration power (smṛti). The concept of endurance, or resilience, is the nexus of adversity intelligence in both Hindu and Western science. According to the Western perspective, human endurance is linked to the body and mind, making it vulnerable to emptiness. Hinduism thrives on fortitude, divine strength, and readiness to accept failure, happiness, and sorrow with a balanced attitude (Stitaprajña) and ready to fight again. Aṣṭāṅga-yoga can be used to improve adversity intelligence. The more enterprising, diligent, disciplined, and earnest one is, the better the results will be. Adversity intelligence can improve endurance, fighting power, and persistence, interpersonal skills, balance, obedience, and devotion, and a sense of higher purpose in life. Human life as a whole will be affected by these effects.

Bacteriophages are viruses that infect bacterial cells and use their machinery to reproduce. This unique characteristic holds immense promise for combating antibiotic-resistant bacterial infections, a growing global threat. There are two types: one of them is named temperate phages, which inject their genomic material into bacteria and integrate into the host’s genome, while the second one is entitled as lytic phages that subdue the entire metabolism of the bacterium for the synthesis of its genome and proteins, including lytic proteins involved in breaking bacterial cell membrane and release of novel phages. In addition, phage therapy can be expressed through anti-biofilm activity and by triggering innate and adaptive immune cells responses. Moreover, no adverse effects of phage therapy have been reported. However, phage therapy is still grim for many and could influence some interpretations related to immune response, bacteriophage selections, and phage resistance in the future.

Nanosafety assessment, which seeks to evaluate the risks from exposure to nanoscale materials, spans materials synthesis and characterisation, exposure science, toxicology, and computational approaches, resulting in complex experimental workflows and diverse data types. Managing the data flows, with a focus on provenance (who generated the data, for what purpose) and quality (how the data was generated, using which protocol, with which controls), as part of good research output management, is necessary to maximise the re-use potential and value of the data. The concept of Instance Maps has been developed and evolved to visualise experimental nanosafety workflows and to bridge the gap between the theoretical principles of FAIR (Findable, Accessible, Interoperable and Re-usable) data and the everyday practice of experimental researchers. While Instance Maps can be created for completed studies or publications, they are most effective when applied at the study design stage to associate the workflow with the nanomaterials, environmental conditions, method descriptions, protocols, biological and computational models to be used and the data flows arising from study execution. Application of the  Instance Map Tool (described herein) to research workflows of increasing complexity is presented to demonstrate its utility, starting from assessment of nanomaterials transformations in complex media, and documentation of nanomaterial synthesis, functionalisation and characterisation, to description of the culturing of ecotoxicity model organisms Daphnia magna and their use in acute and chronic standardised tests for nanomaterials ecotoxicity assessment, and visualisation of complex workflows in human immunotoxicity assessment using cell lines and primary cellular models. These examples showcase the use of the Instance Map approach for coordination of materials and data flows in complex multi-partner collaborative projects, and to support demonstration case studies. Finally, areas for future development of the Instance Map approach and tool are highlighted.
The Star Formation History in Local Group Galaxies. I. Ten Dwarf Galaxies

Published: April 2024

The star formation histories (SFHs) of galaxies provide valuable insights into galaxy evolution and stellar physics. Understanding the SFHs enables the study of chemical enrichment of galaxies, star formation triggered by interactions, and the behavior of various stellar populations. This work investigates the SFHs of ten dwarf galaxies in the Local Group (LG), which spans a wide range of types, masses, luminosities, and metallicities. The analysis is based on our new sample of the member stars in the LG after removing foreground dwarf stars by using information from the near-infrared color–color diagram and Gaia astrometry. The sample includes the most complete and pure red supergiants and asymptotic giant branch stars to gain valuable insights into the recent SFHs of the galaxies. A fitting method based on the color–magnitude diagram (CMD) is introduced to measure the SFH. The Padova isochrones are used to generate initial model CMDs, accounting for photometric errors and completeness through star-field simulations to match the completeness and error distributions of the observed CMDs. Subsequently, the SFHs, distance modulus, and metallicity of the ten dwarf galaxies are determined by fitting the CMDs. The results indicate that the star formation rates of dwarf irregulars show a gradual increase, while those of dwarf ellipticals exhibit a gradual decrease from the past to the present. Furthermore, this work shows that the star formation activity in dwarf ellipticals persisted up to 30 Myr ago. A significant increasing feature in the SFH of NGC 6822 reveals star formation activity triggered by an interaction event.

The results obtained so far suggested a tension between observations and predictions of the ΛCDM model. However, the data set of H(z) direct measurements from cosmic chronometers and baryon acoustic oscillations was quite limited. This motivated us to study the performance of this test on a larger sample obtained in an alternative way. In this paper, we propose that gravitational-wave (GW) standard sirens could provide large samples of H(z) measurements in the redshift range of 0 < z < 5, based on the measurements of the dipole anisotropy of luminosity distance arising from the matter inhomogeneities of the large-scale structure and the local motion of the observer. We discuss the effectiveness of our method in the context of the space-borne DECi-herz Interferometer Gravitational-wave Observatory, based on a comprehensive H(z) simulated data set from binary neutron star merger systems. Our results indicate that in the GW domain, the Omh

Ultrafast Compact Binary Mergers
Authors: Beniamini Paz , Piran Tsvi
Published: April 2024

The duration of orbital decay induced by gravitational waves (GWs) is often the bottleneck of the evolutionary phases going from star formation to a merger. We show here that kicks imparted to the newly born compact object during the second collapse generically result in a GW merger time distribution behaving like

at short durations, leading to ultrafast mergers. Namely, a nonnegligible fraction of neutron star binaries, formed in this way, will merge on a timescale as short as 10 Myr, and a small fraction will merge even on a timescale less than 10 kyr. The results can be applied to different types of compact binaries. We discuss here the implications for binary neutron star mergers. These include unique short gamma-ray bursts (GRBs), eccentric and misaligned mergers, r-process enrichment in the very early Universe and in highly star-forming regions, and possible radio precursors. Interestingly, we conclude that among the few hundred short GRBs detected so far, a few must have formed via this ultrafast channel.
Solar Energetic Particle and the Heliospheric Current Sheet
Authors: Liou Kan , Wu Chin-Chun
Published: April 2024

The effect of the heliospheric current sheet (HCS) on the propagation of solar energetic particles (SEPs) remains poorly known. In this study we address this question by surveying energetic (∼2.0–9.6 MeV nucleon–1) helium data acquired by the energetic particle acceleration, composition, and transport (EPACT) sensor on board the Wind spacecraft. A superposed epoch analysis of 319 HCS crossings made by Wind reveals a sharp drop in the SEP fluxes at the HCS for the low-energy channels and little change across the HCS for the high-energy channels. To help understand the statistical result, we studied a total of 15 SEP flux dropout (a decrease of ∼50% or more) events that coincided with the crossing of the HCS. One of the common features of these SEP events is that they were initiated in the western hemisphere but far away from the longitude of HCS crossings, suggesting that the source of SEPs was well connected initially but was cut off later after Wind moved to the opposite hemisphere (e.g., HCS crossing). Further analysis of the events suggests that the percentage of flux dropouts decreases with increasing energy. It is suggested that a strong scattering of MeV helium may have occurred as the particle gyroradius is comparable to the thickness of the current sheet. This study clearly provides solid evidence for the HCS as a barrier to suppressing SEP flux of MeV energies from the onset hemisphere to the other.
Circumnuclear Multiphase Gas in the Circinus Galaxy. VI. Detectability of Molecular Inflow and Atomic Outflow
Authors: Baba Shunsuke , Wada Keiichi , Izumi Takuma , Kudoh Yuki , Matsumoto Kosei
Published: April 2024

Recent submillimeter observations have revealed signs of parsec-scale molecular inflow and atomic outflow in the nearest Seyfert 2 galaxy, the Circinus galaxy. To verify the gas kinematics suggested by these observations, we performed molecular and atomic line transfer calculations based on a physics-based 3D radiation-hydrodynamic model, which has been compared with multiwavelength observations in this paper series. The major-axis position–velocity diagram (PVD) of CO(3–2) reproduces the observed faint emission at the systemic velocity, and our calculations confirm that this component originates from failed winds falling back to the disk plane. The minor-axis PVD of [C i](3
P
1–3
P
0), when created using only the gas with positive radial velocities, presents a sign of blueshifted and redshifted offset peaks similar to those in the observation, suggesting that the observed peaks indeed originate from the outflow, but that the model may lack outflows as strong as those in the Circinus galaxy. Similar to the observed HCN(3–2), the similar dense-gas tracer HCO+(3–2) can exhibit nuclear spectra with inverse P-Cygni profiles with ∼0.5 pc beams, but the line shape is azimuthally dependent. The corresponding continuum absorbers are inflowing clumps at 5–10 pc from the center. To detect significant absorption with a high probability, the inclination must be fairly edge-on (≳85°), and the beam size must be small (≲1 pc). These results suggest that HCN or HCO+ and [C i] lines are effective for observing parsec-scale inflows and outflows, respectively.

Published: April 2024

The Hobby–Eberly Telescope (HET) VIRUS Parallel Survey (HETVIPS) is a blind spectroscopic program that sparsely covers approximately two-thirds of the celestial sphere and consists of roughly 252 million fiber spectra. The spectra were taken in parallel mode with the Visible Integral-field Replicable Unit Spectrograph (VIRUS) instrument when the HET was observing a primary target with other HET facility instruments. VIRUS can simultaneously obtain approximately 35,000 spectra covering 3470–5540 Å at a spectral resolution of ≈800. Although the vast majority of these spectra cover blank sky, we used the Pan-STARRS1 Data Release 2 Stacked Catalog to identify objects encompassed in the HETVIPS pointings and extract their spectra. This paper presents the first HETVIPS data release, containing 493,012 flux-calibrated spectra obtained through 2023 March 31, as well as a description of the data processing technique. Each of the object spectra were classified, resulting in a catalog of 74,196 galaxies, 4,087 quasars, 259,396 stars, and 154,543 unknown sources.

We have established and released a new stellar index library of the Ca ii triplet, which serves as an indicator for characterizing the chromospheric activity of stars. The library is based on data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low-Resolution Spectroscopic Survey (LRS) Data Release 9. To better reflect the chromospheric activity of stars, we have defined new indices R and R

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick
Authors: Akiba Tatsuya , McIntyre Selah , Madigan Ann-Marie
Published: April 2024

The surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems. The question of how planetary material enters the tidal disruption radius of the white dwarf is currently unresolved. Using a series of N-body simulations, we explore the response of the surrounding planetesimal debris disk as the white dwarf receives a natal kick caused by anisotropic mass loss on the asymptotic giant branch. We find that the kick can form an apse-aligned, eccentric debris disk in the range 30–240 au, which corresponds to the orbits of Neptune, the Kuiper Belt, and the scattered disk in our solar system. In addition, many planetesimals beyond 240 au flip to counterrotating orbits. Assuming an isotropic distribution of kicks, we predict that approximately 80% of white dwarf debris disks should exhibit significant apsidal alignment and a fraction of counterrotating orbits. The eccentric disk is able to efficiently and continuously torque planetesimals onto radial, star-grazing orbits. We show that the kick causes both an initial burst in tidal disruption events as well as an extended period of 100 Myr where tidal disruption rates are consistent with observed mass accretion rates on polluted white dwarfs.

Travailler, travailler encore
Authors: Raulet Gérard
Published: April 2024

La tradition utopique compte autant de projets de société promettant l’avènement d’une ère de loisirs que de projets dans lesquels le travail demeure le pilier de la cohésion sociale. Cette double lignée continue d’inspirer certains programmes politiques, mais à la différence des années 1970 une sorte de résignation semble s’être répandue. Cet article propose, au contact de l’histoire des idées politiques et de la philosophie politique contemporaine, de réexaminer les paradigmes de la conception du travail et de sa place dans la société, et de dresser un bilan des théories et utopies sociales qui ont imaginé comment le règne de la liberté peut s’établir sur le règne de la nécessité. La relecture de la tradition utopique permet de faire justice d’une série de lieux communs. Par exemple la crainte qu’une organisation communautaire trop parfaite, « communiste », ne dissuade de travailler – un argument qui ne cesse de polluer toute réflexion sur une conception sociale globale (et non libéraleindividuelle) de la question du travail.
Les silences de la langue paternelle, transmission et « écrypture »
Authors: Farkas Olivia
Published: April 2024

Partant d’un lapsus, celui d’« écrypture », condensation des signifiants « crypte » et « écriture », ce texte interroge la non-transmission de la langue maternelle du père qualifiée de « langue paternelle » dans les situations de trauma et d’exil, en appui sur les ouvrages d’auteurs hongrois comme décor de l’histoire familiale. À la génération suivante, comment les cryptes paternelles auraient-elles contribué à la transmission des éléments traumatiques vécus avant l’exil ?
La langue maternelle et le langage de la tendresse. Perdus et retrouvés
Authors: Koritar Endre
Published: April 2024

Cet article explore l’impact des premières expériences esthétiques sur le développement de la psyché. Le bain sonore de l’environnement du fœtus puis du nouveau-né est enregistré en tant que mémoire implicite dans l’inconscient non refoulé et transmet un sentiment d’appartenance ou d’aliénation en fonction de la nature des relations objectales maternelles précoces. Dans le cas d’un enfant déplacé de sa culture maternelle précoce, par la fuite et l’émigration, l’acculturation, la perte des images, des sons et odeurs familiers de sa culture d’origine, ce sont autant de stress supplémentaires. Tout comme la perte de la musicalité de la langue. Nous présentons ici le cas clinique d’un jeune patient qui a pu faire le deuil de sa langue maternelle et de sa culture tardivement, après avoir pu revenir sur son lieu de naissance. L’expérience esthétique de sa confrontation à la culture de son village natal et la remémoration de ses premières expériences de vie auprès des personnes qui lui avaient prodigué leurs soins ont ouvert les cryptes de traumatismes longtemps enfouis du passé et l’ont amené au cours de l’analyse à explorer les régions souterraines de son esprit. Cet article soutient que c’est son instinct d’autoconservation qui l’a conduit à la recherche de son passé. Le travail analytique de construction et de reconstruction lui a fourni le récit ayant pu réanimer son instinct de vie affaibli en redonnant du sens et un but à son existence.
Freud, un Janus bifrons ? Freud et sa « psychologie de l’enfant » au tournant du siècle
Authors: Kamieniak Jean-Pierre
Published: April 2024

Si l’objet majeur des recherches du futur conquistador résidait bien dans le devenir libidinal désormais inconscient du sujet humain, faisant de ce dernier un être pulsionnel dès ses débuts aux conduites recouvertes par cette amnésie infantile qu’il identifiera en 1905, il n’en reste pas moins que jusqu’à la publication de L’interprétation du rêve – activité pédiatrique, éducation, analyse d’adultes, paternage et auto-analyse aidant –, c’est un véritable portrait psychologique de l’enfant qu’il brosse à grands traits, partagé qu’il est entre ce laboratoire que sont ses Lettres à l’ami Fließ et cette publication officielle fondamentale de 1900. Aussi est-ce à la fréquentation de cet espace hétérogène, si ce n’est contradictoire, que le lecteur est convié.

Une économie de l’innovation pour les temps à venir
Authors: Foray Dominique
Published: April 2024

L’économie de l’innovation du XX e siècle a été admirable. Elle a permis une amélioration spectaculaire des conditions de la vie quotidienne et a déclenché une élévation massive des niveaux de vie. Cette économie de l’innovation a aussi été décevante. Elle a produit quatre grands problèmes qui aujourd’hui nous frappent en pleine figure. Une nouvelle économie de l’innovation doit répondre à ces problèmes en inventant des mécanismes pour mieux diriger l’innovation. Cependant, les succès précédents ont tenu en partie à un ensemble d’institutions et de valeurs, au premier rang duquel on situera la liberté d’expérimenter de nouvelles idées dans l’économie et l’autonomie des innovateurs vis-à-vis des gouvernements. Comment résoudre cette tension entre liberté et direction ? Comment fonder une nouvelle économie de l’innovation qui conservera certains des ingrédients qui ont permis ce dynamisme extraordinaire tout en développant les outils qui permettront d’affronter les quatre grands problèmes évoqués ?

Les paradoxes de l’innovation ouverte : vers un changement de paradigme pour la Défense
Authors: Mérindol Valérie , Versailles David W.
Published: April 2024

Les politiques d’innovation de Défense apparaissent en contradiction avec l’innovation ouverte car elles sont traditionnellement fondées sur la recherche de stabilité des compétences critiques maîtrisées par un périmètre fermé d’acteurs. À partir de l’étude du cas français, cette recherche montre comment la Défense gère ces paradoxes. Deux modèles d’innovation co-existent et interagissent : l’innovation fermée orientée vers la Base industrielle et technologique de Défense (BITD), et l’innovation ouverte visant à des liens avec une variété d’écosystèmes d’innovation. La gestion de ce modèle bicéphale de l’innovation requiert de recourir à la différenciation et intégration managériale mises en place par une agence de l’innovation. Cela requiert aussi la mobilisation d’une variété d’intermédiaires qui jouent un rôle de capteurs d’idées et de compétences externes à la BITD. Codes JEL : H56, L38, O36, O38
L’anorexie mentale pré-pubertaire. Problèmes dans le transfert et le contre-transfert
Authors: Magagna Jeanne
Published: April 2024

Ce chapitre décrit certaines des complications contre-transférentielles rencontrées dans le travail auprès d’une jeune fille pré-pubère souffrant d’anorexie mentale. Il montre l’importance de s’ajuster à la qualité du silence et de la communication d’un patient, ressentie à travers l’utilisation des observations de la communication non-verbale, des dessins, des rêves et des expériences contre-transférentielles. Il montre également l’utilisation du contrôle destructeur omnipotent comme méthode pour faire face aux angoisses persécutoires. Les facteurs influençant le développement d’une identité féminine saine, en identification à un bon objet interne, sont également discutés.
Être pair, être proche
Authors: Ancet Pierre
Published: April 2024

La définition de la notion de pair n’est pas arrêtée dans la littérature scientifique, et sa définition courante (avoir le même statut et la même fonction) est insuffisamment précise. Un enfant est-il toujours le pair des autres écoliers de sa classe ? Est-il toujours le pair de ses frères et sœurs ? Cela mérite d’être questionné lorsque l’on parle d’un enfant en situation de handicap. Inversement, si l’on évoque le handicap comme critère, est-on nécessairement le pair de quelqu’un qui possède le même type d’atteinte physique ou psychique que soi ? De qui donc nous reconnaissons-nous être les pairs ? Ceux à qui nous ressemblons ou ceux qui nous complètent, ceux nous renvoient une expérience en miroir malgré leur différence ? Nous plaidons ici pour la possibilité d’une conception ouverte de la notion de pair, multiple et contextuelle, que l’on peut rattacher à la reconnaissance subjective d’une expérience commune.
« Maintenant,il a plein de copains ». Les relations d’amitié des personnages avec TSA dans les albums
Authors: Joselin Laurence , Rachedi Zineb
Published: April 2024

Les relations d’amitié constituent un ressort fréquent des trames narratives dans les albums de jeunesse qui mettent en scène un personnage en situation de handicap. Toutefois, certains troubles des personnages peuvent rendre plus difficiles ces interactions sociales. Aussi, après un état de l’art qui permet de rendre compte de la manière dont l’amitié est perçue et vécue par les enfants avec un TSA, l’objectif de cet article est-il d’analyser les relations aux pairs des personnages avec un trouble du spectre de l’autisme. Le corpus comprend quatorze albums de jeunesse, publiés en France entre 2011 et 2022, qui abordent la question de l’amitié entre un personnage avec des troubles du spectre de l’autisme et ses pairs. Les résultats présentent les caractéristiques des personnages avec TSA (dont la variété des manifestations du trouble) et celles de leurs camarades ou amis, avant d’examiner la qualité de la relation d’amitié, selon les variables inspirées de la Friendship Quality Scale (la camaraderie, l’entraide, le réconfort, l’intimité et l’absence de conflit). Hormis quelques exceptions, les trames narratives privilégient le registre didactique et offrent une vision relativement apaisée du trouble du spectre de l’autisme.
