Personality disorders must also be approached from a dimensional perspective always, as it allows more subtle assessments of the dominating temperament and character. As it has both genetic conditionings and social-cultural ones, the Conscientiousness dimension – closely related to activism – centers the personality's structure and it may favor or disadvantage the individual destiny. The adaptive variants of Conscientiousness favor personal self-directedness process, self-control and the subjective well-being. In return, the maladaptive variants – in terms of extremely high or low values, accompany most of the personality disorders. Thus, the psycho-behavioral manifestations of Obsessive-Compulsive Personality Disorder, Borderline Personality Disorder, Antisocial Personality Disorder and Narcissistic Personality Disorder, but also of Avoidant Personality Disorder and Histrionic Personality Disorder may be dimmed, exacerbated or nuanced by the values of Conscientiousness. These are also predictive factors for a diversity of episodes and mental illnesses, in the case of which the therapeutic compliance influences in a decisive manner.

The aim of this paper is the evolution of the biological markers and of alcoholism when the patient diagnosed with alcoholism is undergoing detox treatment. After detox, the biological markers of alcoholism undergo changes as the patient undergoes treatment. As a result of the successive visits for the detox treatment from alcohol, correlations were identified between GGT, GPT and GOT values in the group of patients diagnosed with alcoholism, as well as in the group of the patients with alcoholism and associated hepatopathy. The study aims to investigate a group of patients diagnosed with alcoholism that undergo the detox treatment and the manner in which the biological markers evolve in the case of the patients with alcoholism and associated hepatopathy. The results of the study will be capitalized in the form of a statistical and mathematical model so that clinicians can establish strategies for therapeutic approach for patients with relapses in alcoholism and hepatopathy associated to alcoholism.

Introduction: There is an increase in incidence of autism among children. The development of comprehensive therapeutic approaches and techniques for the recovery of those affected becomes a necessity. Moreover, evaluating the progress and the results of the therapeutic interventions, as well as identifying the clinical variables that can influence the quality of the response to therapy are just as important. Objectives: This paper aims to analyze the progress and results of an early intensive behavioral intervention. Methods: The current study was conducted in 116 children aged between 2 and 5 years old with an autism diagnosis. The developmental domains are evaluated with the ADOSG test. We analyzed the variation of ADOS score consequently to applied therapy, as well as the influence of comorbidities such as ADHD or intellectual disability on the patient's progress. Results: Our results show that after 2 years of EIBI, the ADOS-G total score decreased on average with 2,98 points, and for 14 children this score was below the diagnostic threshold. Comorbidities did not have an influence on the progress. These results certify the efficiency of EIBI therapies and encourages the start of a therapeutic program independent of the severity of the symptoms or associated pathologies.

Published: June 2023

This study describes the level of cognitive mapping among students in one of the senior high schools in Indonesia. This study aimed to determine the cognitive map of secondary students using a sketch map. The cognitive map elements studied were paths, edges, landmarks, districts, and nodes. This research uses an interpretive paradigm to reveal how students make meaning of their school environment through map sketches. The research approach used was descriptive qualitative. Data collection techniques included a map sketching test and direct interviews with six randomly selected key informants. Cognitive map analysis was used to analyse the cognitive map elements in students' map sketches. The results showed that second-grade students have diverse cognitive maps of their school environment. Thus, this study recommends that attention and substantial efforts from various parties, especially geography subject teachers, be more intense in utilising the surrounding environment as a geography learning laboratory at SMUK ST.

EXPLORING TOURIST RESPONSE TO FRIENDLY ENVIRONMENTAL DESIGN AND PERCEIVED VALUE ON TOURIST VISITATION INTENTION OF ADULT-CHILDREN TRAVELING WITH THEIR PARENTS
Authors: Lin Jiin-Ling , Chao Ren-Fang
Published: June 2023

The purpose of this study is to explore the travel decision-making of a specific type of traveler, adultchildren, and their aged parents. The study examines the impact of an age-friendly environment and perceived value on the tourist’s travel intention. The results show that in addition to the significant impact of perceived value on tourism intentions, age-friendly environmental design has also been confirmed to play a mediating role between the above two dimensions. This phenomenon indicates that good age-friendly environmental design is indeed a key factor in adult-child and parent travel decision-making.
Praktik Media Relations pada Pemerintahan Kota Bandung
Authors: Apriliyanti
Published: June 2023

ABSTRACT

The government as an institution that represents the public interest requires media channels to maintain its reputation. The purpose of writing this article is to determine the practice of media relations carried out by the city government of Bandung. In conducting this research the writer used a qualitative descriptive research method using investigative interview techniques and in-depth interviews so that they were able to describe the results of observations and analyze the data obtained in the field. After analyzing and discussing the problem, the authors conclude that the media relations practices that occur in Bandung city government tend to be too "intimate". This has led to the practice of giving "envelopes". The forms of "envelopes" given by government agencies to journalists include transportation money, news money, THR and Eid gifts and souvenirs, souvenirs, wedding gifts or birthday gifts, and press trips. However, most of the journalists who covered considered what they received was not an “envelope” category. They think it is their right, and must be accepted because of pamali if they have to refuse fortune. Meanwhile, for the public relations staff, the gift is considered normal only as a form of appreciation and gratitude.

Keywords: public relations, media relations, government public relations.

ABSTRAK

Pemerintah sebagai Lembaga yang merepresentasikan kepentingan publik membutkan saluran media untuk menjaga reputasinya. Tujuan penulisan artikel ini adalah untuk mengetahui praktik media relations yang dilakukan oleh pemerintah kota Bandung. Dalam melakukan penelitian ini penulis menggunakan metode penelitian deskripsi kualitatif dengan menggunakan teknik wawancara investigasi dan in-depth interview sehingga mampu menggambarkan hasil observasi dan menganalisa data-data yang diperoleh dilapangan. Setelah melakukan analisis dan pembahasan masalah, penulis memperoleh kesimpulan bahwa praktik media relations yang terjadi di pemerintahan kota Bandung cenderung terlalu “mesra”. Hal tersebut menimbulkan adanya praktik pemberian “amplop”. Bentuk-bentuk “amplop” yang diberikan oleh dinas pemerintahan kepada wartawan diantaranya berupa uang transportasi, uang berita, THR dan bingkisan lebaran dan souvenir, souvenir, kado pernikahan atau kado ulang tahun, dan press trip. Namun, sebagian besar wartawan yang meliput menganggap apa yang mereka terima bukan termasuk dalam kategori “amplop”. Mereka beranggapan itu sudah merupakan hak mereka, dan harus diterima karena pamali kalau harus menolak rejeki. Sedangkan bagi staf humas sendiri, pemberian tersebut dianggap wajar hanya sebagai bentuk penghargaan dan bentuk rasa terimakasih.

We investigate general relativistic magnetohydrodynamic simulations to determine the physical origin of the twisty patterns of linear polarization seen in spatially resolved black hole images and explain their morphological dependence on black hole spin. By characterizing the observed emission with a simple analytic ring model, we find that the twisty morphology is determined by the magnetic field structure in the emitting region. Moreover, the dependence of this twisty pattern on spin can be attributed to changes in the magnetic field geometry that occur due to the frame dragging. By studying an analytic ring model, we find that the roles of Doppler boosting and lensing are subdominant. Faraday rotation may cause a systematic shift in the linear polarization pattern, but we find that its impact is subdominant for models with strong magnetic fields and modest ion-to-electron temperature ratios. Models with weaker magnetic fields are much more strongly affected by Faraday rotation and have more complicated emission geometries than can be captured by a ring model. However, these models are currently disfavoured by the recent EHT observations of M87*. Our results suggest that linear polarization maps can provide a probe of the underlying magnetic field structure around a black hole, which may then be usable to indirectly infer black hole spins. The generality of these results should be tested with alternative codes, initial conditions, and plasma physics prescriptions.
Tracer Particles for Core-collapse Supernova Nucleosynthesis: The Advantages of Moving Backward

Published: June 2023

After decades, the theoretical study of core-collapse supernova explosions is moving from parameterized, spherically symmetric models to increasingly realistic multidimensional simulations. However, obtaining nucleosynthesis yields based on such multidimensional core-collapse supernova simulations is not straightforward. Frequently, tracer particles are employed. Tracer particles may be tracked in situ during the simulation, but often they are reconstructed in a post-processing step based on the information saved during the hydrodynamic simulation. Reconstruction can be done in a number of ways, and here we compare the approaches of backward and forward integration of the equations of motion to the results based on inline particle trajectories. We find that both methods agree reasonably well with the inline results for isotopes for which a large number of particles contribute. However, for rarer isotopes that are produced only by a small number of particle trajectories, deviations can be large. For our setup, we find that backward integration leads to better agreement with the inline particles by more accurately reproducing the conditions following freeze-out from nuclear statistical equilibrium, because the establishment of nuclear statistical equilibrium erases the need for detailed trajectories at earlier times. Based on our results, if inline tracers are unavailable, we recommend backward reconstruction to the point when nuclear statistical equilibrium was last applied, with an interval between simulation snapshots of at most 1 ms for nucleosynthesis post-processing.
LIMFAST. II. Line Intensity Mapping as a Probe of High-redshift Galaxy Formation

Published: June 2023

The epoch of reionization (EoR) offers a unique window into the dawn of galaxy formation, through which high-redshift galaxies can be studied by observations of both themselves and their impact on the intergalactic medium. Line intensity mapping (LIM) promises to explore cosmic reionization and its driving sources by measuring intensity fluctuations of emission lines tracing the cosmic gas in varying phases. Using LIMFAST, a novel seminumerical tool designed to self-consistently simulate LIM signals of multiple EoR probes, we investigate how building blocks of galaxy formation and evolution theory, such as feedback-regulated star formation and chemical enrichment, might be studied with multitracer LIM during the EoR. On galaxy scales, we show that the star formation law and the feedback associated with star formation can be indicated by both the shape and redshift evolution of LIM power spectra. For a baseline model of metal production that traces star formation, we find that lines highly sensitive to metallicity are generally better probes of galaxy formation models. On larger scales, we demonstrate that inferring ionized bubble sizes from cross-correlations between tracers of ionized and neutral gas requires a detailed understanding of the astrophysics that shape the line luminosity–halo mass relation. Despite various modeling and observational challenges, wide-area, multitracer LIM surveys will provide important high-redshift tests for the fundamentals of galaxy formation theory, especially the interplay between star formation and feedback by accessing statistically the entire low-mass population of galaxies as ideal laboratories, complementary to upcoming surveys of individual sources by new-generation telescopes.
Detection of X-Ray Polarized Emission and Accretion-disk Winds with IXPE and NICER in the Black Hole X-Ray Binary 4U 1630−47
Authors: Rawat Divya , Garg Akash , Méndez Mariano
Published: June 2023

We detect a high level of polarization in the X-ray emission of the black hole binary 4U 1630–47 in an observation with the Imaging X-ray Polarimetry Explorer. The 2–8 keV polarization degree is 8% at a position angle of 18°, with the polarization degree increasing significantly with energy, from ∼6% at ∼2 keV to ∼11% at ∼8 keV. The continuum emission in the spectrum of simultaneous observations with the Neutron Star Interior Composition Explorer (NICER) is well described with only a thermal disk spectrum, with stringent upper limits to any Comptonized emission from the corona. Together with the lack of significant variability in the Fourier power spectrum, this suggests that the source was in the high soft state at the time of these observations. The NICER spectrum reveals the presence of several absorption lines in the 6–9 keV band that we fit with two ionized absorbers, providing evidence of the presence of a strong disk wind, which supports the idea that the source was in the soft state. Previous measurements of X-ray polarization in other sources in harder states were associated with the corona or the jet in those systems. Given that the corona is significantly absent in this observation of 4U 1630–47, and that the jet in black hole binaries is quenched in the high soft state, we speculate that in this observation of 4U 1630–47, the polarization likely arises from the direct and reflected radiation of the accretion disk in this source.
JWST/NIRSpec Measurements of the Relationships between Nebular Emission-line Ratios and Stellar Mass at z ∼ 3–6

Published: June 2023

We analyze the rest-optical emission-line ratios of star-forming galaxies at 2.7 ≤ z < 6.5 drawn from the Cosmic Evolution Early Release Science (CEERS) Survey and their relationships with stellar mass (M
*). Our analysis includes both line ratios based on the [N ii] λ6583 feature ([N ii] λ6583/Hα, ([O iii] λ5007/Hβ)/([N ii] λ6583/Hα) (O3N2), and [N ii] λ6583/[O ii] λ3727) and those featuring α-elements ([O iii] λ5007/Hβ, [O iii] λ5007/[O ii] λ3727 (O32), ([O iii] λλ4959, 5007 + [O ii] λ3727)/Hβ (R23), and [Ne iii] λ3869/[O ii] λ3727). Given the typical flux levels of [N ii] λ6583 and [Ne iii] λ3869, which are undetected in the majority of individual CEERS galaxies at 2.7 ≤ z < 6.5, we construct composite spectra in bins of M
* and redshift. Using these composite spectra, we compare the relationships between emission-line ratios and M
* at 2.7 ≤ z < 6.5 with those observed at lower redshift. While there is significant evolution toward higher excitation (e.g., higher [O iii] λ5007/Hβ, O32, O3N2) and weaker nitrogen emission (e.g., lower [N ii] λ6583/Hα and [N ii] λ6583/[O ii] λ3727) between z ∼ 0 and z ∼ 3, we find in most cases that there is no significant evolution in the relationship between line ratio and M
* beyond z ∼ 3. The [Ne iii] λ3869/[O ii] λ3727 ratio is anomalous in showing evidence for significant elevation at 4.0 ≤ z < 6.5 at fixed mass, relative to z ∼ 3.3. Collectively, however, our empirical results suggest no significant evolution in the mass–metallicity relationship at 2.7 ≤ z < 6.5. Representative galaxy samples and metallicity calibrations based on existing and upcoming JWST/NIRSpec observations will be required to translate these empirical scaling relations into ones tracing chemical enrichment and gas cycling and to distinguish among descriptions of feedback in galaxy formation simulations at z > 3.
Preatmospheric Detection of a Meter-sized Earth Impactor

Published: June 2023

On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound sensors in Hawaii. The USG measurements reported a steep entry angle of 67° from horizontal from a radiant 13° east of north and an impact speed of 11.7 km s−1. Interpretation of all energy yields produces a preferred energy estimate of 0.4 kt TNT, corresponding to a 23,000 kg, 3 m diameter meteoroid. A postimpact search of telescopic images found that the Asteroid Terrestrial-impact Last Alert System survey captured the object just 10 minutes prior to impact at an Earth-centered distance of nearly 11,900 km with apparent magnitude m = 12.5. The object appears as a 0.44° streak originating on the eastern edge of the image, extending one-third of the USG state-vector-based prediction of 1.26° over the 30 s exposure. The streak shows brightness variability consistent with small asteroid rotation. The position of Earth’s shadow, the object’s size, and its consistency with the reported USG state vector confirm the object is likely natural. This is the eighth preatmospheric detection of a near-Earth asteroid (NEA) impactor and the closest initial telescopic detection prior to impact. The high altitude of peak fireball brightness suggests it was a weak object comparable in many respects with 2008 TC3 (the Almahata Sitta meteorite), with an absolute magnitude H = 32.5 and likely low albedo. Therefore, we suggest the NEA was a C-complex asteroid.

Vers une nouvelle carte énergétique de l’Amérique latine
Authors: Velut Sébastien
Published: June 2023

La guerre d’Ukraine met en lumière les tendances contradictoires à l’œuvre dans le système énergétique mondial. D’un côté, la consommation d’hydrocarbures n’a jamais été aussi élevée, de l’autre, le déploiement des renouvelables n’a jamais été aussi rapide, et l’électrification progresse partout. L’Amérique latine, prudente dans ses engagements climatiques, reflète ces tendances. Les grands barrages hydroélectriques, existants et en construction, permettent d’afficher une production électrique décarbonée, particulièrement au Brésil et dans les pays Andins. Les gisements de renouvelables font l’objet de grands projets d’exploitation, du Mexique à la Patagonie. La production des hydrocarbures pourrait connaître un renouveau, en bénéficiant de nouvelles localisations, de nouvelles technologies et d’un retour sur les marchés du Venezuela. C’est la carte énergétique de l’Amérique latine qui est en train de changer.
La copossession du monde
Authors: Cretois Pierre
Published: June 2023

Dans cet article, nous interrogeons la possibilité d’une critique libérale du droit de propriété. En effet, le libéralisme économique nous a plutôt invité à voir dans le droit de propriété le fondement ultime de l’ordre social mutuellement bénéfique permis par le marché. Pourtant, cette thèse interprétative fait peu de cas d’autres façons libérales de relativiser la propriété exclusive notamment parce qu’elle met en danger le droit que les démunis ont d’accéder aux ressources nécessaires à une vie véritablement libre. L’approche que nous proposons dans cet article consiste à penser l’entrelacement du propre et du commun ou à penser le propre sur la base de ce que nous appellerons la copossession du monde. Une telle copossession du monde n’est pas conçue comme un renversement du libéralisme politique classique mais comme un renouvellement de celui-ci dans une perspective qui soit compatible avec les défis sociaux et environnementaux de notre époque.
La quadrature du cercle. Commun, communauté et immunité
Authors: Kaufmann Laurence
Published: June 2023

Pour explorer la question du bien commun, il n’est jamais inutile de revenir aux enjeux et aux origines de la notion de communauté. Après avoir comparé les formes sociales et politiques mais aussi géométriques de la « communauté » et de la « société », cet article se penche sur la distinction entre communauté et immunité que propose Roberto Esposito. Une fois déployée l’identité catégorielle, et non pas relationnelle, qu’implique la déclinaison « immunitaire » de la communauté, il s’agira de proposer une conception plus réaliste et plus obligeante du co-munus . Une telle conception fait miroiter une autre forme sociale que celle, pesante, du cercle qui attache et enferme la « communauté » ou que celle, superficielle, de la ligne qui traverse et fissure la « société » : celle, triangulaire , du « public » et de la voie des « communs » qu’il est susceptible de creuser, entre la propriété privée et l’État souverain.
La ville entre innovation sociale et « communification »
Authors: Festa Daniela
Published: June 2023

Les communs n’ont pas été seulement un mouvement d’en bas pour réclamer des espaces et des ressources matérielles et symboliques. Ils ont marqué également un changement profond dans la façon dont nous concevons la ville et ses institutions. Inscrits dans un long processus de transformation de l’identité urbaine de plus en plus caractérisée par une multiplicité d’acteurs et de stratégies, les communs ont ainsi influencé les politiques urbaines par des voies différenciées, parfois composites, parfois divergentes. Cette contribution analyse des différents chemins qui ont conduit en Italie et, plus largement en Europe, à l’émergence de ladite « commonification » des politiques urbaines et locales en mettant en évidence des effets à la fois innovants et ambivalents.
Utopies sobres. La politique des communs des éprouvés
Authors: Le Blanc Guillaume
Published: June 2023

La politique des plus démunis, loin d’être une pauvre politique, est en avance d’un monde. Le fait que la vie pauvre impose un style de vie sobre, que cette sobriété soit le corollaire d’un impératif de survie non négociable suggère une utopie politique d’autant plus partageable que sa pratique, en lien avec des communs préservés, instaure un mode d’existence humain moins prédateur, susceptible d’un usage respectueux des ressources de la planète et nouvelles alliances avec les autres êtres vivants. Ainsi, la sobriété des styles de vie pauvres se confond avec la revendication écologique d’une sobriété planétaire et la revendication d’une solidarité entre les vies.
Le corps-continent

Dans la tradition de Marcel Mauss et de Georg Simmel, David Le Breton analyse le corps comme un « fait social total ». Sa socio-anthropologie du corps est à la fois une anthropologie philosophique, symbolique et existentielle de l’être-au-monde, une sociologie interactionniste de l’action et une sociologie critique de la modernité. En explorant toutes les facettes de son œuvre foisonnante sur le corps, les émotions, les sensations, l’identité, la douleur, le risque, les jeunes, etc., l’article brosse un portrait émouvant de David Le Breton dans tous ses états.
De la construction d’une administration sociale à son éclatement

Published: June 2023

L’administration sociale a été particulièrement malmenée par des réformes incessantes qui ont touché tant le niveau central que son organisation déconcentrée et décentralisée. Celles-ci ont certes répondu à une forte croissance des services rendus et des dépenses sociales, mais, contribuant à l’enchevêtrement des administrations sociales, ont généré une complexité et une instabilité qui limitent efficacité et lisibilité. Les tentatives de simplification, de transversalité, de coopération administrative et d’organisation d’une participation des usagers restent à développer.
La place de la direction générale de la cohésion sociale (DGCS) par rapport aux autres administrations et opérateurs de l’État dans les politiques sociales nationales : conception et mise en œuvre
Authors: Vinquant Jean-Philippe
Published: June 2023

L’action de l’État en matière de cohésion sociale a été fortement impactée par les profondes mutations du champ de l’action sociale, du fait des politiques de décentralisation, de la création de nouveaux opérateurs, mais aussi de l’évolution des enjeux sociaux (vieillissement, fragilité du lien familial, aggravation des difficultés d’accès à l’emploi, progression du « sans-abrisme », montée de l’exclusion dans certains territoires, inégalités entre les femmes et les hommes…) et des aspirations à une entière citoyenneté des personnes les plus fragiles. La direction générale de la cohésion sociale, de création récente (2010), mais héritière de plus de soixante-dix ans d’existence de la première direction « sociale » de l’État, a traversé de nombreuses évolutions des dispositifs et institutions sociales. Elle est restée la direction la plus « généralement et largement » compétente sur ces sujets et garde donc une profonde singularité, tout en devant s’articuler avec de plus nombreuses autres administrations, institutions, et opérateurs comme la Caisse nationale de solidarité pour l’autonomie. La gestion de la crise de la Covid-19 et la conférence des métiers du médico-social et du social de 2022 l’ont fortement mise à contribution, et ont montré l’utilité, au sein de l’État, de pouvoir s’appuyer sur une direction « très sociale » et transversale.

The neutron diffusion equation (NDE) is one of the most important partial differential equations (PDEs), to describe the neutron behavior in nuclear reactors and many physical phenomena. In this paper, we reformulate this problem via Caputo fractional derivative with integer-order initial conditions, whose physical meanings, in this case, are very evident by describing the whole-time domain of physical processing. The main aim of this work is to present the analytical exact solutions to the fractional neutron diffusion equation (F-NDE) with one delayed neutrons group using the Laplace transform (LT) in the sense of the Caputo operator. Moreover, the poles and residues of this problem are discussed and determined. To show the accuracy, efficiency, and applicability of our proposed technique, some numerical comparisons and graphical results for neutron flux simulations are given and tested at different values of time $ t $ and order $ \alpha $ which includes the exact solutions (when $ \alpha = 1). $ Finally, Mathematica software (Version 12) was used in this work to calculate the numerical quantities.
Complete solutions of the simultaneous Pell's equations $ (a^2+2)x^2-y^2 = 2 $ and $ x^2-bz^2 = 1 $
Authors: Dou Cencen , Luo Jiagui
Published: June 2023

In this paper, we consider the simultaneous Pell equations $ (a^2+2)x^2-y^2 = 2 $ and $ x^2-bz^2 = 1 $ where $ a $ is a positive integer and $ b > 1 $ is squarefree and has at most three prime divisors. We obtain the necessary and sufficient conditions that the above simultaneous Pell equations have positive integer solutions by using only the elementary methods of factorization, congruence, the quadratic residue and fundamental properties of Lucas sequence and the associated Lucas sequence. Moreover, we prove that these simultaneous Pell equations have at most one solution in positive integers. When a solution exists, assuming the positive solutions of the Pell equation $ (a^2+2)x^2-y^2 = 2 $ are $ x = x_m $ and $ y = y_m $ with $ m\geq 1 $ odd, then the only solution of the system is given by $ m = 3 $ or $ m = 5 $ or $ m = 7 $ or $ m = 9 $.
Taking part in the evaluation of security and prevention policies. Trials of citizen participation in Brussels
Authors: Caprasse Valérie
Published: June 2023

Au départ d’un matériau empirique constitué notamment de focus groupes menés avec des professionnels de l’évaluation des services de prévention communaux et avec des citoyens bruxellois, cet article revient sur certains enjeux de la participation citoyenne à l’évaluation des politiques de sécurité et de prévention en Région bruxelloise. D’une part, la nature même de ces politiques soulève des questions éthiques qui appellent, des vœux des acteurs professionnels, à des garanties procédurales. D’autre part, l’absence de certains profils de la population dans les dispositifs participatifs bruxellois interroge les acteurs professionnels et aboutit à la formulation de pistes, tant par les évaluateurs que par les citoyens rencontrés, pour tendre vers des processus plus inclusifs. Enfin, la production de nouvelles connaissances par la participation des citoyens se trouve également au cœur des enjeux identifiés.

Published: June 2023

Background

Although a shortage of organ donors is a continuing global problem in health care, obtaining authorization for donation after an individual experiences a traumatic nonsurvivable event can be difficult.

Objective

To improve organ donation practices at a level II trauma center.

Methods

After reviewing trauma mortality cases and performance improvement metrics with their organ procurement organization’s hospital liaison, leaders at the trauma center implemented a multidisciplinary performance improvement initiative to engage the facility’s donation advisory committee, provide education for staff members, and increase program visibility to create a more donation-friendly culture for the facility.

Results

The initiative led to an improved donation conversion rate and a greater number of organs procured. Continued education increased staff and provider awareness of organ donation, contributing to the positive outcomes.

Conclusion

A multidisciplinary initiative that includes continuing staff education can improve organ donation practices and program visibility, ultimately benefiting patients in need of organ transplantation.
Human IL-35 Inhibits the Bioactivity of IL-12 and Its Interaction with IL-12Rβ2

IL-35 is an immunosuppressive cytokine with roles in cancer, autoimmunity, and infectious disease. In the conventional model of IL-35 biology, the p35 and Ebi3 domains of this cytokine interact with IL-12Rβ2 and gp130, respectively, on the cell surface of regulatory T and regulatory B cells, triggering their suppression of Th cell activity. Here we use a human IL-12 bioactivity reporter cell line, protein binding assays, and primary human Th cells to demonstrate an additional mechanism by which IL-35 suppresses Th cell activity, wherein IL-35 directly inhibits the association of IL-12 with its surface receptor IL-12Rβ2 and downstream IL-12–dependent activities. IL-12 binding to the surface receptor IL-12Rβ1 was unaffected by IL-35. These data demonstrate that in addition to acting via regulatory T and regulatory B cells, human IL-35 can also directly suppress IL-12 bioactivity and its interaction with IL-12Rβ2.

Aflatoxin M1 (AFM1) is a well-known carcinogenic compound that may contaminate milk and dairy products. Thus, with the regulation 1881/2006, the European Union established a concentration limit for AFM1 in milk and insisted on the importance of defining enrichment factors (EFs) for cheese. In 2019, the Italian Ministry of Health proposed four different EFs based on cheese’s moisture content on a fat-free basis (MMFB) for bovine dairy products. This study aimed to define the EFs of cheese with different MFFB. The milk used for cheesemaking was naturally contaminated with different AFM1 concentrations. Results showed that all the EF average values from this study were lower than those of the Italian Ministry of Health. Hence, the current EFs might need to be reconsidered for a better categorization of AFM1 risk in cheese.
Goal setting and intervention based on the international classification of functioning, disability, and health for a patient with chronic spinal cord injury
Authors: Mishra Ashwini Vidyasagar , Ganvir Suvarna S.
Published: June 2023

Patients with spinal cord injury (SCI) have alteration in motor and sensory function leading to disability. The International Classification of Functioning, Disability, and Health (ICF) framework offers physical therapists a common understanding and a standardized language to describe functioning. Hence, the purposes of this case report were to apply ICF-based documentation tools to the care of patients with SCI. A 31-year-old male, 9 years post-SCI (C7, ASIA B), completed 4 months of physiotherapy treatment. The problem list was based on ICF and training was emphasized on bed mobility, sitting balance, hand training, and transfer. After receiving physiotherapy treatment, there was an improvement in the functional status of the patients, i.e. activities of daily living, transfer, and standing and little improvement in the strength of lower limb muscle. The ICF Core Set reflects the importance of impairments, limitations, and activity participation in SCI patients. The case study has shown an improvement in chronic SCI patients, and it has been reflected through the ICF qualifier scale.
Ethics and Politics of Induced Abortion and the Sanctity of Human Life
Authors: Oluwa Donatus , Orji Joseph , Ogoko Albert
Published: June 2023

This research work argues that induced abortion as a means of birth control is morally unacceptable. Although, the question of abortion is being considered as a means of birth control but this position not only has generated much controversy from antiquity to the postmodern era, it has also politicized many democratic societies. Proponents of induced abortion couch it in terms of gender equality and human right of women to choose or what to do in matters that their body. This too has presented us with political and ethical quandary. The problematic as conceptualized in the title is embedded in moral questions implied in these questions, among others, regarding the morality of induced abortion and the politicization of the ethical question. What makes one’s choice right or wrong? Is it one’s choice that makes an act right? Isn’t it first, that an act is judged right according to certain ethical norms that makes the action morally justified? Thus, some ethicists and pro-abortion advocates argue first, that the fetus is mere potency in the act of becoming human, and can be terminated at no moral consequence; secondly, that a woman has the right terminate the fetus as means of birth control. The researchers adopted the qualitative research design and used the expository, critical and analytic methods in the study to bring to the fore the crux of the matter. Major ethical theories are explored, critical questions raised and moral implications of exponents’ views exposed. The researchers came up with the conclusion that though human life is inviolable, even that of the unborn child. However, applying the Catholic Church’s moral teaching on the principle of double effect, the work avers that there could be extenuating circumstances, when induced abortion can be indirectly willed, such as in the case of treatment of a cancerous uterus, ectopic pregnancy, etc. Contrarily, it is the position of the researchers that politicizing abortion on the ground of the wellbeing of the couple, the human right of the pregnant woman to choose, for political capitals, or for eugenics reasons is intrinsically evil and thus acceptable. Politicizing induced abortion as a means of birth control has far reaching implications on ethics and the dignity of life. The paper strongly recommends that concerted efforts be put in place for educating married couples on the ethical implications of human sexuality. In this direction those in government should synergize with the Catholic Church’s magisterium on this issue and enact laws that protect the rights of the unborn child.
