Published: July 2024

Reforestation is one of the important activities that must be implemented conceptually in dealing with the environmental crisis. This reforestation needs to be done through environmental education. Reforestation can be done if there is a will from each individual, for example the will of PKK women. This will will be the basis for implementing the reforestation program in Motinelo Village, Tabongo District, Gorontalo Regency. Departing from the description above, it is necessary to do community service, namely empowering PKK women in environmental greening activities in Motinelo Village, Tabongo District, Gorontalo Regency. Reforestation is very useful in overcoming various degradations in environmental quality by using the main material is the use of plants that are very functional in the biotic environment of the environment. The purpose of this service is to increase awareness of PKK women about the importance of carrying out environmental greening activities in order to maintain environmental quality and protection in the Motinelo Village, Tabongo District, Gorontalo Regency. This community empowerment activity aims to carry out reforestation activities through tree planting to improve environmental quality. In addition, this activity also aims to increase public awareness about environmental conservation. The environmental reforestation activity that will be carried out hopes that problems regarding the declining quality of the environment can be overcome by involving community participation. This is the essence of community empowerment, which can provide benefits to the community, especially PKK women in terms of environmental management. Another benefit that can be felt by the community is the increased awareness of PKK mothers on the importance of protecting the environment through reforestation.

The development of the home industry is currently increasingly stretched and is important for economic growth for the country. The more businesses, the more jobs. Micro, Small and Medium Enterprises (MSMEs) are also an important pillar in economic growth, so it is necessary to innovate to make it easier for MSMEs to carry out their roles and activities after the COVID-19 pandemic. However, its development still has obstacles, one of which is the difficulty in obtaining business legality and formality. The problem of MSMEs in the aspect of obtaining business permits and certification must be a serious concern, because the costs are relatively large and need assistance. Anticipating this requires a policy that is able to guarantee and protect business actors so that they can compete in the midst of global economic liberalization. This is experienced by MSMEs in Bendungan Village which consists of several business groups such as; Palm Sugar Producers, Pastries and Egg Nut Manufacturing Groups, who do not yet have legality such as a business license. Based on the existing problems, the solutions offered are specifically in Bendungan village, namely; Counseling on licensing and certification laws. The implementation of this counseling aims to provide understanding to the community, especially business actors to register their products so that they have legality and are recognized for their validity in the community. Not only that, training and Business Management Guidance were also carried out such as product packaging. Counseling was carried out in collaboration with the Office of Investment and Energy and Mineral Resources of Boalemo Regency as a resource person. The licensing process only needs to be done in a system (online) on the Online Single Submission (OSS) page by entering personal data in the form of the business owner's KTP and NPWP. Having a permit for this business makes it easier for people to market their products in supermarkets, and provides opportunities for people to get financial support from the government. While other activities are training in making packaging for community business products accompanied by students. Constraints faced by the community such as ownership of NPWP, it is suggested to the sub-district and village governments to hold a management and procurement program directly in the village to make it easier for the community. In addition, the village needs to map out the marketing locations for community business products and support packaging for the progress of the village, through economic empowerment in home industries.

In modern pig farming, when producing meat products, special attention is paid to interbreeding and hybridization. Crossbreeds are characterized by a higher level of productivity, which is due to better vitality compared to purebred animals. Biochemical studies of animal blood have always occupied a prominent place among the methods for objective assessment of metabolic processes in the body and the patterns of formation of economically useful traits. The study of blood parameters makes it possible to observe an objective lifetime assessment of the intensity and direction of metabolism, the course of physiological processes in the body, the level of nutrition of animals, and their health status. Therefore, in accordance with the above, knowledge of the nature and patterns of variability in the biochemical parameters of pig hybrids is of particular interest. Our article reflects the results of a study of biochemical blood parameters of three-breed hybrid pigs.

Cylindrical cell, especially with the 18650 format, is widely used for power electronics and electric vehicle. The cell's performance is strongly dictated by the current rate of charge/discharge and the cell temperature. The former is relatively easy to gauge because the value is constant for a certain period. Therefore, the cell performance can be mapped with respect to the current rate. However, the cell temperature varies temporally and dimensionally, making mapping cell performance concerning temperature difficult. This study employs a comprehensive thermal approach, with the aim to evaluate the degree of thermal variation with respect to various testing temperatures and cell arrangements conducted in a thermal chamber. Thermal measurements are measured, such as cell surface temperature at various cell locations. The experimental results provide an insight that different testing arrangements in which the cell is suspended vertically and horizontally do not alter the temperature variation of the cell significantly. Nevertheless, temperature difference up to 3oC is manifested along the cell surface, which happens at 5oC ambient temperature. This analysis highlights that cell temperature on the surface of 18650 cell is highly non-uniform, and the data could be further used to facilitate the cell's cooling system in for cells in this nature.
Microwave Ablation Therapy for Hepatocellular Carcinoma: The Effect of Metabolic Heat on Temperature Distribution
Authors: Heaven Josiah Harvan  , Slamet Wahyudi  , Winarto
Published: July 2024

Hepatocellular carcinoma is the main cause of liver cancer and one of the most occurring cancers worldwide. Microwave Ablation (MWA) is a method to destroy cancer cells by heating tumors above 50°C. Cancerous tissues can have high metabolic heat rates and affect temperature gain and distribution in thermal therapies. This research clarifies the metabolic heat effects in MWA therapy of liver cancer. Using Pennes Bioheat transfer equation with finite element numerical method, this research simulates temperature distribution with metabolic heat value ranging from 368,1 W/m3 to 29000 W/m3. The heat generated by metabolic heat is lower than the MWA heat source. However, the temperature increase should be considered as it can increase healthy surrounding tissue temperature to dangerous levels.
Effect of Chamfered Turbulators on Performance of Solar Air Heater - Numerical Study

Published: July 2024

This paper presents a numerical analysis of the thermal performance improvement in a flat plate solar air heater equipped with chamfered turbulators attached below the absorber plate for evaluating performance for Reynolds numbers ranging from 3,000 to 21,000. According to the research, chamfered turbulators caused the flow to become highly turbulent. This flow behaviour with flow separation around the turbulators positively affects performance. This paper attempts to explain the complex flow behaviour found during the analysis. The turbulator diameter varies in 1 mm increments from 3 to 7 mm at a constant longitudinal pitch of 200 mm. The number of turbulator rows in the transverse direction is kept constant at three. The chamfer is represented by the flow attack angle, which can be 30°, 45°, or 60° facing the direction of flow and opposing the direction of flow. The results showed that a 7mm diameter turbulator with a 30° chamfer angle placed against the flow of air yielded a considerably more significant thermal enhancement factor of 1.15 over the spectrum of flow Reynolds number studied
Investigating the Actuation of Sidewall Sprinkler in an Atrium Using CFD Simulation
Authors: Jaime III Reyes  , Jaime Honra
Published: July 2024

This study investigates the actuation of sidewall sprinklers in large-scale buildings with high-ceilinged atriums, addressing the challenges of unique architectural configurations. Compliance with NFPA 101 requires automatic sprinkler systems, including atrium areas, in these buildings. To maintain aesthetic considerations, design engineers, particularly in the middle east, often propose sidewall sprinklers as an alternative to traditional ceiling sprinklers. This research assesses whether the sidewall sprinklers would actuate during a fire using Fire Dynamic Simulator (FDS). The findings indicate that sidewall sprinklers will fail to actuate if the fire is located at the centre of the atrium, even if the edge of the fire area is below the sprinklers. Furthermore, the study emphasizes the importance of using an FDS mesh resolution (D*/dx) of 6 or finer resolution when measuring temperatures near the flame or fire plume to ensure accurate evaluations of sprinkler activation. These findings provide valuable insights for design engineers and authorities, assisting in decision-making processes related to fire safety measures, system designs, and regulatory compliance.

Cybercrime and its Implications on the Economy of Nigeria
Authors: Fitswemila Philip Stephanie
Published: July 2024

One of the tenets of globalization is the advancement of Information and Communication Technology (ICT) mainly achieved through computer interconnectivity enabled by the internet in a presumed market place known as cyber space where both buyers, sellers and users in the form of individuals, corporate bodies and government meet. These interconnectivity brought about economic opportunities and inclusion. One of the areas so developed is the e-commerce sector where communication and interactions in the form of transaction is hinged on instant exchange of information, goods and services but, as friendly as these interactions are, they are not without their consequences- Cybercrime is one which often comes with huge financial loss and economic impact. Nigeria in its quest to liberalize trade and digitalize its transactions adopted the use of emerging technologies and services to drive the change but the tools and methods used to enhance the transactions are oftentimes misused by cybercriminals to their benefit thereby causing huge financial losses for the victims and invariably impact negatively on the economy. This research reviewed some existing literature on the subject of cybercrime, and its manifestations within the financial sector while relying on the Social Learning Theory as the reason for the prevalence of cybercrime among youths. Data was drawn and questionnaires administered. Analysis was done using CHI square in the Statistical Package for Social Sciences (SPSS). The study, therefore, concluded that there is a significant relationship between Cybercrime and the Nigerian economy and that Cybercrime had impacted negatively on the growth and development of the digital economy, in particular, and the Nigerian economy at large. Finally, the study offers solutions on how the Internet can engage the various Internet-based platforms, particularly calling on institutions responsible for combating this crime to put every effort required to end this menace.

Developing Papuan State Civil Apparatus Competencies and Love for the Republic of Indonesia
Authors: Salomina Hendrina Sawai Anna Oktovina
Published: July 2024

Various development policies have been implemented for 61 years in Papua, but until now the welfare of the Papuan people has been far from expectations. This can be seen from the 2023 Papua Human Development Index which is in the medium category. Apart from development problems there is also the problem of political instability. The government continues to take a security and welfare approach but has not made progress in Papua. It is suspected that one of the causes of this failure is that the duties, functions, and roles of the Papuan SCA have not been optimal. Therefore, it is necessary to develop the competency of Papuan SCA through managerial training, namely, Training on PCS, SLT, ALT and NLT-Level II. Papuan SCAs have taken part in the training based on the national curriculum, but it turns out there are still thoughts of propaganda for an independent Papua. This has a negative impact on future development, so the development of SCA competencies with the national curriculum needs to be reviewed; Has the managerial training curriculum fostered Papuan SCA's love for the Republic of Indonesia and is there a managerial training model that can foster love for the Republic of Indonesia? The objectives of this KTI are Describes the love of Papuan SCAs for the Republic of Indonesia based on the implementation of the national curriculum and describes a managerial training model that can foster Papuan SCAs' love for the Republic of Indonesia. The method used is descriptive qualitative. The results of the research show that the national managerial training curriculum has fostered a love of Papuan SCA. It is realized that Papua has local wisdom, historical background and socio- cultural characteristics as well as development facts that are far from expectations, so the national curriculum needs to be integrated with Papuan local content, namely; Based on the local wisdom, history and socio-cultural values of the Papuan people, the managerial training curriculum in Papua is integrated into a "Papuan style" local wisdom curriculum in order to foster Papuan civil servants' love for the Republic of Indonesia.
The Creation and Utilization of Transistors
Authors: Murtadha Hamza Ibrahim S.
Published: July 2024

The transistor is a crucial component in modern electronics, enabling the miniaturization and improvement of electronic systems. Its invention in 1947 by John Bardeen, Walter Brattain, and William Shockley at Bell Labs marked a revolutionary breakthrough in electronic technology. The transistor's compact, energy- efficient, and reliable nature allowed for the development of smaller, faster, and more reliable electronic devices. Since its inception, the transistor has undergone numerous innovations and advancements, evolving from the original point-contact transistor to the highly efficient and compact field-effect transistors (FETs) and metal- oxide-semiconductor field-effect transistors (MOSFETs) used today. These advancements have facilitated the development of increasingly complex and powerful electronic systems, including computers, smartphones, and the vast networks that form the backbone of the internet. The ongoing research and development in transistor technology continues to push the boundaries of what is possible, driving progress in fields ranging from computing and telecommunications to healthcare and renewable energy. The transistor's significance cannot be overstated; it is a cornerstone of modern technology and a key driver of innovation and economic growth.
Decoloniality in Theology Today: The Quest to Liberate United Theological College’s Curriculum from Foreign God Talk
Authors: Mujinga Martin
Published: July 2024

United Theological College is one of the oldest and largest ecumenical institutions in Southern Africa. The institution brings together six Protestant churches in Zimbabwe. For years, the institution produced competent theologians. Unfortunately, these theologians drunk from some foreign theological calabashes whose contents are divorced from the Zimbabwean realities. The College had been clinging to the Western, far distant, and neighbouring African theologies and theologians for its curriculum forgetting to scratch where Zimbabweans are itching. This collection of different theologies into one combination was an attempt by the College to equip students with diversified theologies from different sociopolitical, economic, and religious environments, ignoring that the context is divorced from Zimbabwe’s milieu. This paper sought to invoke the institution’s continual addressing of contextual theological issues using borrowed theological epistemologies. Using a decolonial framework and qualitative research methodology, the paper challenged the institution to decolonise its curriculum by liberating it from armchair theories of foreign God talk. Structurally, the paper discussed the theoretical framework, methodology, and identity of the College and proceeded to present the curriculum of the institution and the findings from the interviews with special reference to four modules. The paper stressed that the perpetual pontification of foreign theological themes by the institution will continue to create theologians whose heads and the body are separated. The conclusion challenged the College to decolonise its curriculum and advocate for a theology that speaks with the language and idioms of the Zimbabwean milieu regardless of the challenges associated with the move. This paper contributes significantly to scholarship as it challenges United Theological College to use relevant resources to do theology.

We present the discovery of VHS J183135.58−551355.9 (hereafter VHS J1831−5513), an L/T transition dwarf identified as a result of its unusually red near-infrared colors (J − K
S = 3.633 ± 0.277 mag; J − W2 = 6.249 ± 0.245 mag) from the VISTA Hemisphere Survey and CatWISE2020 surveys. We obtain low-resolution near-infrared spectroscopy of VHS J1831−5513 using the Magellan Folded port InfraRed Echellette spectrograph to confirm its extremely red nature and assess features sensitive to surface gravity (i.e., youth). Its near-infrared spectrum shows multiple CH4 absorption features, indicating an exceptionally low effective temperature for its spectral type. Based on proper-motion measurements from CatWISE2020 and a photometric distance derived from its K

s
-band magnitude, we find that VHS J1831−5513 is a likely (∼85% probability) kinematic member of the β Pictoris moving group. Future radial velocity and trigonometric parallax measurements will clarify such membership. Follow-up mid-infrared or higher-resolution near-infrared spectroscopy of this object will allow for further investigation as to the cause(s) of its redness, such as youth, clouds, and viewing geometry.
A Strong Falsification of the Universal Radial Acceleration Relation in Galaxies
Authors: Chan Man Ho
Published: July 2024

In the past few decades, many studies revealed that there exist some apparent universal relations that can describe the dynamical properties in galaxies. In particular, the radial acceleration relation (RAR) is one of the most popular relations discovered recently that can be regarded as a universal law to connect the dynamical radial acceleration with the baryonic acceleration in galaxies. This has revealed an unexpected close connection between dark matter and baryonic matter in galaxies. In this article, by following the recent robust Galactic rotation curve analyzes, we derive the Galactic RAR (GRAR) and show for the first time that the alleged best-fit universal RAR deviates from the GRAR data at more than 5σ. This provides a strong evidence to falsify the universal nature of RAR in galaxies claimed in past studies.

We explore the formation of the intragroup light and intracluster light, representing diffuse lights within groups and clusters, from the point that z = 1.5. For this, we perform multiresolution cosmological N-body simulations using the “galaxy replacement technique” and identify the progenitors in which the diffuse light stars existed when they fell into the groups or clusters. Our findings reveal that typical progenitors contributing to diffuse lights enter the host halo with massive galaxies containing a stellar mass of

are more prominent, with over half of them already preprocessed before entering the host halo. Additionally, we find that the main formation mechanism of diffuse lights is the stripping process of satellites, and a substantial fraction (40%–45%) of diffuse light stars are linked to the merger tree of the brightest cluster galaxy. Remarkably, all trends persist for groups and clusters at higher redshifts. The fraction of diffuse lights in the host halos with a similar mass decreases as the redshift increases, but they are already substantial at z = 1.5 (∼10%). However, it is crucial to acknowledge that detection limits related to the observable radius and faint-end surface brightness may obscure numerous diffuse light stars and even alter the main formation channel of diffuse lights.

Published: July 2024

The stellar spectra from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) medium-resolution survey can be used to search for compact objects in binaries. The LAMOST Data Release 10 catalog includes >980,000 targets with multiple medium-resolution spectra. We select the targets with large or rapid radial-velocity variation, and obtained an input sample of 1822 sources. We use light curves and spectra to identify and exclude eclipsing binaries and double-lined spectroscopic binaries in the input sample. We finally derive a catalog of 89 candidates with well-folded radial velocity, which are all single-lined spectroscopic binaries, indicating an unseen companion residing in each system. The mass function of each system can be well constrained based on the radial-velocity curve. In our sample, 26 sources have mass function higher than 0.1 M
⊙, among which 18 sources have ellipsoidal-type light curves. In our opinion, compact objects are likely existent in all these 26 binaries, which are worth follow-up identification.

, the first significant detection of a nonequatorial hotspot in an exoplanet atmosphere. We show that this detection is robust to variations within planetary parameter uncertainties, but only if the transit is used to improve constraints, showing the importance of transit observations to eclipse mapping. Maps retrieved from the NRS1 and NRS2 detectors are similar, with hotspot locations consistent between the two detectors at the 1σ level. Our JWST data show brighter (hotter) nightsides and a dimmer (colder) dayside at the shorter wavelengths relative to fits to Spitzer 3.6 and 4.5 μm phase curves. Through comparison between our phase curves and a set of general circulation models, we find evidence for clouds on the nightside and atmospheric drag or high metallicity reducing the eastward hotspot offset.
The Delayed Radio Emission in the Black Hole X-Ray Binary MAXI J1348-630
Authors: You Bei , Yang Shuai-kang , Yan Zhen , Cao Xinwu , Zdziarski Andrzej A.
Published: July 2024

We explore the coupling between the accretion flow and the jet in black hole X-ray binary MAXI J1348-630 by analyzing the X-ray and radio observations during its 2019 outburst. We measure the time delay between the radio and Comptonization fluxes with the interpolated cross-correlation function. For the first time, we find that the radio emission lags behind the X-ray Comptonization emission by about 3 days during the rising phase covering the rising hard state and the following soft state. Such a long radio delay indicates that the Comptonization emission most likely originates from the advection-dominated accretion flow rather than the jet in this source. The Comptonization luminosity L
C in 0.1–100 keV and the radio luminosity L
R at 5.5 GHz, after considering the radio delay of ∼3 days, follow the correlation with a slope β = 3.04 ± 0.93, which is much steeper than the previously reported β = 0.6 or 1.40 using the total luminosity in the limited band (e.g., 1–10 keV) in the literature. This highlights the necessity of considering (1) the time delay, (2) the spectral decomposition, and (3) the broad energy band, in the radio–X-ray correlation analysis. As the jet reappears during the decaying phase (covering the soft state and the following decaying hard state) and the mini-outburst, the Componization and the radio emission appear to be almost simultaneous. And, the radio-Compton correlation during the mini-outburst becomes shallow with the correlation slope β = 1.11 ± 0.15. These indicate an intrinsic difference in the accretion–jet coupling physics between the main outburst and the mini-outburst.

Various types of metal-organic frameworks (MOF) and their structural parameters have been reviewed and their classification has been presented. Most widely used synthesis methods and approaches for MOF and composites on their basis have been discussed. MOF structure is a regular 3D lattice formed by organic linkers and metallic clusters. It has been shown for an example of literary data on MOF synthesis and structural studies that the types of bonds and metals can strongly affect the spatial structure and dimensions of MOF crystals: they can have nano-, micro- and meso-dimensions, be dense or porous, bulk or layered. This variety of structural parameters determines the wide range of their properties and potential applications.

Prospects and methods of controlling the shapes of the crystals, their size and spatial bonds between organic components and metal ions have been reviewed.

Major attention has been paid to zeolite-like frameworks (ZIF) as the most promising ones from the viewpoint of structure, synthesis and electrochemical current source applications. Discussion has touched on possible modifications and methods of controlling the properties of those MOFs and composites on their basis and introduction of impurities, including those having magnetic properties. Possible synthesis options of complex composites through controlled MOF pyrolysis have been presented, for either small-batch or scalable processes. The effect of heat treatment conditions on the final properties and electrochemical applications of those materials has been demonstrated.

ZIF-67 structured MOF doping with one more metal has been presented as variant of modifying the properties of MOF and composites on their basis. For example, the Authors have implemented cobalt MOF synthesis wherein cobalt is partially substituted for manganese at the synthesis stage. Furthermore, a simple water solution co-deposition synthesis technique has been modified with ultrasonication thus reducing the time consumption of the process. Electrochemical studies have shown that the unit electrochemical capacity of pyrolyzed MOF electrodes with partial cobalt substitution for manganese is appreciably higher as compared to the manganese-free materials. The unit capacity and energy density increase with manganese content in the MOF. MOF manganese doping delivers a considerable improvement in the electrochemical parameters of the electrode materials for hybrid supercapacitors on their basis (from 100 to 298 F/g at 0.25 A/g current density). The results suggest that cobalt substitution for manganese is an effective method of improving the electrochemical parameters of MOFs.

It has been demonstrated that the development of new approaches to the design of MOF based composite materials and the study of the physicochemical regularities of their interaction with various carriers is an important task.

This paper presents the results of obtaining and studying the electrical and optical characteristics of an optically transparent highly conductive Ni/Cu/Ti/ITO contact in order to reduce electrical resistance losses on the front side of the silicon solar cell. The topology of the contact metallization is a square 50 × 50 mm2 with an interdigitated electrode structure. A Ni/Cu/Ti contact metallization formed on ITO layer reduces the surface resistance by more than 60 times. It has been shown that the use of a Ni/Cu/Ti contact with a finger thickness of at least 1.5 μm and a width of 17 μm was formed is a good alternative to traditional contacts for silicon solar cells based on silver paste.
L’enveloppement, un soin dans le cadre des psychothérapies d’enfants : quels enjeux ?
Authors: Vesely-Lesourd Nathalie
Published: July 2024

Ce texte présente une pratique de soin psychique par enveloppement du corps de l’enfant dans une couverture lestée. La démarche clinique est illustrée par des témoignages d’enfants. Ils évoquent pour la plupart l’idée d’un apaisement après les enveloppements et même plusieurs semaines après. Les parents évoquent une amélioration comportementale et les enfants semblent bien moins dans l’opposition. Par conséquent, il conviendrait d’intégrer cette pratique en pensant toute la complexité de la mise en œuvre du dispositif comme un soin psychique. L’autrice aborde également les éléments contre-transférentiels impliqués lors des enveloppements. Le clinicien doit penser ses propres affects d’agressivité et doit être en mesure de recevoir une forte charge destructrice contre laquelle il ne doit pas lutter mais prêter son appareil à penser pour que quelque chose de l’altérité puisse se déployer et permettre à ses enfants de tisser leur propre histoire.
Favoriser et soutenir la rencontre mère-enfant en accueil familial

Published: July 2024

Quand un magistrat prend la décision de confier précocement un nourrisson en placement avec séparation, cela constitue une mesure de protection majeure, nécessitant de prendre du temps à la rencontre avec le service, avec la famille d’accueil, et tout particulièrement l’assistante familiale, et enfin avec son ou ses parents. Tous ces temps sont des moments précieux pour tenter de tisser des liens, dans un maillage permettant la construction d’advenir du sujet. De la pouponnière départementale à la salle de visite médiatisée d’un service de placement familial, le temps se déroule, s’écoule et favorise la construction du lien.

Dans un moment de violent traumatisme collectif, l’auteure recherche, à travers l’étude de l’archétype du guérisseur blessé, la dimension symbolique et archétypale de la blessure comme possibilité d’ouverture à l’étranger en soi et à l’extérieur de soi, à l’instar du concept d’hospitalité de Jacques Derrida.
Accélération du processus d’individuation : Le mythe de Méduse et Persée en temps de guerre
Authors: Mouchot Claire
Published: July 2024

WithUkrainianJungians ou #WUJ (mai 2022-mai 2024) a eu pour objectif de soutenir et d’accompagner les collègues ukrainiens souffrant des horreurs de la guerre. Initialement conçue comme un événement unique, cette initiative s’est développée en actions multiples proposées par la communauté jungienne internationale à l’ensemble de la communauté jungienne ukrainienne. Cet article met l’accent sur les groupes de lecture (automne 2022) et la série de webinaires (janvier 2023-mai 2024) au cours desquels différents types de relations ont été établis entre collègues ukrainiens et non-ukrainiens. Une interprétation de cette expérience partagée, recourant aux concepts jungiens, est proposée, qui s’adosse au mythe de Méduse et Persée. Elle présente une analyse des facteurs possibles ayant contribué à l’accélération du processus d’individuation chez les collègues ukrainiens, et à la mobilisation de la psyché pour les bénévoles impliqués dans le #WUJ : l’état de guerre, les rencontres régulières avec les membres de #WUJ et la communauté jungienne internationale.
Images alchimiques dans Cent ans de solitude
Authors: Angel Mata Miguel , Lacour Laurence
Published: July 2024

L’article explore les perspectives symboliques dans Cent ans de solitude de Gabriel García Márquez, afin de rendre compte des complexités de l’Amérique latine en tant que réalité résistante aux utopies occidentales, ou à l’Occident comme utopie. En ce sens, l’alchimie est prise en compte, non pas comme une des dimensions de l’œuvre, mais comme fil conducteur du roman et comme un exercice d’imagination active de l’auteur, à travers lequel il parvient à transformer sa vie, sa littérature et la manière dont la région est comprise. À partir de l’herméneutique symbolique inaugurée par Jung, nous entrons dans l’articulation entre la réalité psychique-individuelle de Gabriel García Márquez et la réalité de l’histoire de sa famille, de la Colombie et de l’Amérique latine, en élaborant et en transformant à l’instar de l’alchimie, les principaux complexes latino-américains et occidentaux. Ceci permet un niveau de compréhension de nos réalités locales au-delà des données historiques et sociologiques conventionnelles. Dans cette perspective, l’auteur s’éloigne de la vision anticoloniale redevable à l’historicisme marxiste, pour rendre compte du mythe de la rencontre permanente de deux mondes, mais également de l’homme avec la nature, de l’homme avec le féminin refoulé et avec lui-même. C’est le mythe fondateur d’un cosmos, où les uns et les autres se rencontrent, se combattent, s’aiment, se croisent et engendrent des démons. Macondo devient ce lieu de l’imaginaire collectif où se confondent réel et imaginaire, individuel et collectif, temps historique linéaire et temps cyclique ; le lieu où l’Occident rencontre son ombre.
Les divers moteurs de la politique familiale et l’objectif du taux de natalité dans les pays de l’OCDE
Authors: Saraceno Chiara
Published: July 2024

Les politiques familiales diffèrent selon les pays et peuvent être regroupées selon leurs objectifs principaux, leur cohérence et leur ampleur. Des résultats récents sur l’impact de différentes politiques indiquent que des congés maternité et parentaux longs et bien rémunérés ainsi qu’une offre suffisante de places dans les établissements d’accueil du jeune enfant ont un impact positif et durable sur la fécondité. Les allocations familiales ont aussi des effets positifs, mais éphémères. Les données sur l’impact du rééquilibrage des responsabilités en matière de garde d’enfant sont quant à elles trop rares pour être concluantes, mais elles suggèrent un impact négatif ou nul. Il conviendrait par ailleurs de prêter attention à l’impact différentiel possible des politiques familiales sur les différents groupes sociaux.
Politique familiale et fécondité en Suède
Authors: Le Bouteillec Nathalie
Published: July 2024

Depuis 2010, la natalité suédoise diminue progressivement d’année en année. Cette baisse s’est récemment accélérée, inquiétant démographes et personnalités politiques. En Suède, la politique familiale a plusieurs objectifs mais le plus saillant, celui qui fait de la politique familiale suédoise une référence, est la facilitation de l’articulation entre vie familiale et vie professionnelle et la volonté que les parents, quel que soit leur genre, puissent s’investir auprès de leurs enfants sans obstacle dû à la vie professionnelle. Cette politique s’appuie, depuis le début des années 1970, sur des congés parentaux généreux et sur un système de services d’accueil préscolaire de très bonne qualité. Depuis leur mise en place, ces mesures n’ont pas connu de transformations majeures. Par conséquent, comment expliquer la baisse de la fécondité actuelle ?
