K-Means Hybridization with Enhanced Firefly Algorithm for High-Dimension Automatic Clustering
Authors: Afroj Alam  , Muhammad Kalamuddin Ahamad
Published: November 2023

K-means clustering is not able to select the right number of clusters of data items having high-dimension. So, for determining the ideal number of clusters, we have combined PCA with the Silhouette and Elbow approaches. Additionally, we have a large number of meta-heuristic swarm intelligence algorithms which is influenced by nature and were previously used to solve the automatic data clustering problem. Firefly offers reliable and effective automatic data clustering. The Firefly algorithm automatically divides the entire population into subpopulations, which slows down the convergence and reduces the of capturing local minima in high-dimensional optimization problems. Thus, for automatic clustering, we demonstrated an improved firefly, i.e., we offered a hybridized K-means with an ODFA model. The experimental section displays the results and graphs for the Silhouette, Elbow, and Firefly algorithms.

Magnetic Field Signatures of Intermediate-sized Impact Craters on Mars
Authors: Zhang Kuixiang , Du Aimin , Huang Can , Luo Hao , Tian Lin , Ge Yasong , Qin Jipeng , Wang Lei
Published: November 2023

Magnetic field signatures over impact craters provide constraints for the history of the Martian dynamo. Due to limitations of the spatial resolution of magnetic field models, previous studies primarily focused on large impact craters (mostly ≥ 500 km in diameter). To fill the impact crater age gaps of previous studies, we investigate the magnetic field signature of 23 intermediate-sized craters (150–500 km in diameter) on Mars using both MAVEN data and a magnetic field model. Ten impact craters located in the South Province, the unmagnetized primordial crust, exhibit no or weak magnetic field signatures. The other 13 impact craters produce stronger magnetic anomalies, with the ratio of the averaged magnetic field inside and outside the craters (B
in/B
out) ranging from 0.4 to 1.2. The B
in/B
out values exhibit correlation coefficients of −0.54, −0.57, and −0.69 with the diameters of craters, calculated from the MAVEN data, the crustal field model at the surface, and 150 km altitude, respectively. A B
in/B
out larger than 1.0 usually appears in craters with smaller diameters, which is also demonstrated by the forward modeling in this study. Furthermore, the results of the forward modeling indicate that the craters of stronger magnetizations show a larger B
in/B
out. According to this, the Martian dynamo can be associated with the magnetization of craters of different ages, and the characteristic time of the dynamo can be limited. Our study supports the hypothesis that the Martian dynamo weakened or ceased at ∼4.0 Ga and a late dynamo was perhaps active at ∼3.7 Ga.
An Asymmetric Double-degenerate Type Ia Supernova Explosion with a Surviving Companion Star
Authors: Siebert Matthew R. , Foley Ryan J. , Zenati Yossef , Dimitriadis Georgios , Schmidt Eva , Yang Grace , Davis Kyle W. , Taggart Kirsty , Rojas-Bravo César
Published: November 2023

We present nebular spectroscopy of SN 2020hvf, a Type Ia supernova (SN Ia) with an early bump in its light curve. SN 2020hvf shares many spectroscopic and photometric similarities to the carbon-rich high-luminosity “03fg-like” SNe Ia. At >240 days after peak brightness, we detect unambiguous emission from [Ca ii] λ
λ7291, 7324, which is rarely observed in normal SNe Ia and only seen in peculiar subclasses. SN 2020hvf displays “sawtooth” emission profiles near 7300 Å that cannot be explained with single symmetric velocity components of [Fe ii], [Ni ii], and [Ca ii], indicating an asymmetric explosion. The broad [Ca ii] emission is best modeled by two velocity components offset by 1220 km s−1, which could be caused by ejecta associated with each star in the progenitor system, separated by their orbital velocity. For the first time in an SN Ia, we identify narrow (FWHM = 180 ± 40 km s−1) [Ca ii] emission, which we associate with a wind from a surviving, puffed-up companion star. Few published spectra have sufficient resolution and the signal-to-noise ratio necessary to detect similar narrow [Ca ii] emission; however, we have detected similar line profiles in other 03fg-like SNe Ia. The extremely narrow velocity width of [Ca ii] has only otherwise been observed in SNe Iax at late times. Since this event likely had a double-degenerate “super-Chandrasekhar” mass progenitor system, we suggest that a single white dwarf (WD) was fully disrupted and a wind from a surviving companion WD is producing the observed narrow emission. It is unclear whether this unique progenitor and explosion scenario can explain the diversity of 03fg-like SNe Ia, potentially indicating that multiple progenitor channels contribute to this subclass.
Functional morphology of the genitalia of Rhyacophila lezeyi Navas, 1933 (Trichoptera, Rhyacophilidae)
Authors: Kuranishi Ryoichi B. , Sato Ryo , Murakami Masashi
Published: November 2023

We collected seven fixed pairs of Rhyacophila lezeyi during mating copulation and observed four different states of copulation. We investigated the underlying mechanism for the variations in the morphology of each copulating device, based on the copulation state. Notably, the male anal sclerites underwent considerable changes from the early stages of copulation. Initially, the female segment VIII approached the male anal sclerites, which were pushed downwards by the female VIII and IX segments, extending from IX. With the progression of mating stage, the distended end of the female’s segment VIII covered the anal sclerites, pushing them further down. The male parameres were initially folded in bellows-like shapes under the aedeagus before copulation initiation. However, as the copulation stage advanced, they extended to about 3.2 times of their original length. Distended ends of both parameres adhered to the position of the spiracles at the anterior margin of the lateral part of the female’s VII abdominal sternite. The attachment site was the external surface of the hair bulb of the male parameres. During the middle stage of copulation, movements involving the opening and closing of the male gonopods started. The gonoslylus made strong contact with the female’s abdominal segment VIII, resulting in the deformation of segment VIII due to the contact pressure.

Sensitisation, research and management for conservation within ESPOL University forests after the COVID-19 pandemic, Ecuador
Authors: Villalba-Briones Ricardo , Piedrahita Paolo Michael , Garces Daniel Omar , Monrós Juan S.
Published: November 2023

Non sustainable land uses are disturbing natural habitats and wild animals’ ecology worldwide. Nevertheless, the sensitisation of key actors combined with research and a consequent management can influence decision-making and improve animals’ well-being. COVID-19 has influenced the number of interactions with wildlife in urban environments and the ESPOL Polytechnic University is a university campus that holds forested areas in Guayaquil, Ecuador. We implemented an environmental education course with an empathetic approach for the security guards of the university. We used questionnaires to evaluate their attitudes and knowledge on wildlife before and after the sensitisation course. In addition, we registered the incidences of native fauna resulting from the guards’ collaborations and we designed management strategies according to the data gathered. The guards showed an improvement in their knowledge of the issues covered (n = 81–87; X̄ = 163.4%) and an increased preference for wild and native fauna after the sensitisation course (n = 67; 151.6%). Furthermore, the collaborations of guards with the Biodiversity Unit of the university concerning animal-human interactions increased, as did the supporting actions towards the well-being of native animals. Moreover, the information about direct and indirect interactions with wildlife included reports on traces of large to medium animal activity and a record of illegal hunting of Choloepus hoffmanni for bushmeat consumption. Obtained data sustained adaptive management actions such as signalling and restrictions in use. We recommend educating key actors with an empathetic approach, developing critical skills and promoting collaborations to reduce human impacts in wild areas.
The Weaponisation of Artificial Intelligence: Risks and Implications
Authors: Felician Beccari Stefano , Bressan Matteo
Published: November 2023

Les fonctions de l’intelligence artificielle (IA) font aujourd’hui l’objet de débats dans les universités, les entreprises et les gouvernements. Mais la possibilité d’appliquer le potentiel de l’IA aux systèmes militaires soulève de nouvelles questions et implications. Le risque est que, dans un avenir proche, les systèmes d’armes létales autonomes (« LAWS »), alimentés par l’IA, soient capables d’échapper au contrôle humain et de libérer leurs effets mortels sans aucune limite ni retenue. Cette possibilité fait l’objet de débats dans lesquels les implications militaires, morales, juridiques et technologiques des « systèmes (d’armes) commandés par intelligence artificielle » doivent être soigneusement évaluées, afin d’être prêtes lorsque, dans le futur, ces technologies apparaîtront sur les champs de bataille. L’objectif de cet article est d’offrir une vue d’ensemble des principales implications de l’IA dans le domaine militaire, y compris des références à des scénarios de conflit ouvert.
Pour une démocratisation de la séparation des pouvoirs de Montesquieu : l’« Unité d’action » de Condorcet
Authors: Cretin-Sombardier Marie
Published: November 2023

Si l’organisation des pouvoirs, promue par l’esprit de modération de Montesquieu, consiste moins à séparer les pouvoirs qu’à les faire collaborer, elle conduit néanmoins à une séparation qui ne dit pas son nom. Sa technique de la séparation des pouvoirs s’appuie sur une distinction sociale et politique entre gouvernant et gouverné pour maintenir le peuple souverain séparé du pouvoir. Contrairement aux fins décrites par Montesquieu et soutenues par ses successeurs démocrates, la séparation des pouvoirs n’est pas un levier de libéralisation ou de démocratisation du pouvoir, mais un frein. Révolutionnaire et critique d’un esprit de modération anti-populaire, Condorcet propose une organisation du pouvoir configurée pour une démocratie représentative. Sous le nom de « l’Unité d’action », il défend une articulation constitutionnelle capable de réconcilier ce que la séparation des pouvoirs divise en déplaçant l’axe de collaboration entre gouverné et gouvernant en faveur du peuple souverain.
Souveraineté du peuple et pouvoir constituant chez Condorcet
Authors: Darriulat Gabriel
Published: November 2023

Cette contribution est consacrée à l’analyse du concept de pouvoir constituant chez Condorcet. Elle montre que si Condorcet limite l’exercice du pouvoir souverain par le peuple au nom des exigences de la raison politique, en déléguant notamment le pouvoir législatif à un corps représentatif, sa pensée fait pleinement droit à l’exigence démocratique d’une participation immédiate du peuple à l’exercice du pouvoir constituant. Celle-ci lui apparaît nécessaire pour sauvegarder l’association politique de la tendance spontanée du pouvoir à agir indépendamment de l’opinion des gouvernés.

Published: November 2023

Contexte et objectif : Le vécu d’une patiente souffrant d’un cancer de sein est associé fréquemment à des troubles anxieux et dépressifs qui sont sous diagnostiqués donc sous traités. L’étude a eu pour objectif de déterminer la prévalence de la dépression et de l’anxiété chez les patientes souffrant de cancer du sein à Ouagadougou au Burkina Faso. Méthodologie : cette étude a été transversale et descriptive portant sur les patientes souffrant de cancer du sein et suivies dans les services de chirurgie digestive et générale du Centre hospitalier universitaire Yalgado Ouédraogo et de l’hôpital Schiphra de Ouagadougou. Nos données ont été collectées du 1er juillet au 31 Août 2021 à l’aide d’un hétero-questionnaire comportant les aspects sociodémographiques et cliniques des patientes, le Mini international psychiatric review pour le diagnostic de la dépression, l’échelle de Beck pour l’intensité de la dépression et l’échelle de Hamilton pour évaluer l’anxiété. Résultats : 102 patientes ont pris part à notre étude. L’autopalpation des seins a été la principale modalité de découverte du cancer dans 74,51 % des cas. La prévalence du trouble dépressif était de 39,21 % dans notre étude. Selon l’intensité de la dépression on retrouvait 10 % d’épisode dépressif léger, 47,5 % moyen et 42,5 % sévère. 55,92 % des patientes présentaient une altération de l’image de soi, 43,14 % une tristesse exprimée et 42,17 % un impact sur leur autonomie physique. On notait la présence d’idées suicidaires dans 8,82 %. La prévalence de l’anxiété était de 45,1 %. L’anxiété a été caractérisée légère dans 45,65 % des cas, modérée dans 30,43 % et sévère dans 23,91 % des cas. Symptômes urinaires et génitaux étaient présents dans 62,74 % et l’insomnie dans 54,90 % des cas. 82,5 % des patientes qui présentaient une dépression avaient une anxiété associée. Discussion et conclusion : la prévalence de la dépression et de l’anxiété dans notre étude traduit la nécessité de mettre en place une composante psychologique et psychiatrique dans la prise en charge des patientes souffrant de cancer du sein.
Esquisse d’une Théorie critique de la consommation éthique
Authors: Ferrarese Estelle
Published: November 2023

« Même si elles sont datées par bien des aspects, les thèses de l’École de Francfort sur le marché et la consommation permettent de mettre au jour les contours et les manques de la critique du capitalisme que constitue la consommation éthique contemporaine. Nous en discutons dans cet article deux éléments. D’une part, la consommation éthique repose sur le postulat qu’il est possible et nécessaire d’injecter des normes morales dans le marché, posé comme en étant dépourvu. Or, la question de savoir si le marché est arraché aux normes, ou s’en donne simplement l’apparence, est le lieu d’un débat complexe au sein de la Théorie critique. Déplier les arguments avancés aide à comprendre comme nécessaire le désajustement des intentions morales des consommateurs et des effets de leurs pratiques sur le monde. D’autre part, la consommation éthique appelle à une forme de vertu qui serait à même de briser le fétichisme de la marchandise, engageant à ne pas oublier ce qui se tient derrière la relation entre des choses (des travailleurs, des personnes singulières, de la peine, etc.) dont l’illusion réificatrice est instituée par le marché. La discussion, par Adorno et Benjamin tout particulièrement, de ce thème marxien du fétichisme permet de mettre en évidence l’insuffisance du geste éthique pour amender ou réformer le capitalisme. »
Les conditions de la non-éducation et la répression de la sexualité
Authors: Olivier Alain Patrick
Published: November 2023

« L’une des manifestations principales de l’emprise du néolibéralisme autoritaire sur la vie des individus consiste dans la destruction des systèmes publics d’éducation ayant pour fonction de former le citoyen et d’émanciper l’homme. s’agit-il seulement d’un échec des politiques d’éducation ? Ou ne s’agit-il pas plutôt de projets de non-éducation ? La philosophie de Theodor W. Adorno permet de penser les conditions de ce que nous appelons ici la non-éducation, en suivant une approche critique, négative et dialectique. Nous en actualisons, dans cet article, plusieurs thèmes, permettant d’éclairer la situation présente : 1) la pensée mythique, 2) l’industrie culturelle, 3) les pratiques autoritaires. À cela s’ajoute une condition portant sur 4) les tabous liés à la sexualité. certes, lorsqu’Adorno traite de l’éducation et de l’émancipation, la question de la sexualité – ou de sa répression – n’apparaît pas au premier plan. permet-elle de mettre au jour des limites du projet critique lui-même ? Ou d’éclairer certains tabous qui lui seraient inhérents, lesquels refléteraient aussi certains tabous du monde enseignant ? »
« Décoloniser » la Théorie critique ? Une hypothèse de travail sur Adorno et la decolonialidad
Authors: Scafoglio Luca
Published: November 2023

« L’approche de la « decolonialidad » , telle qu’elle a été élaborée par Dussel, Quijano, Mignolo, Castro-Gomez, Lugones, Maldonado Torres et Grosfoguel, met en avant l’actualité du colonialisme. La « colonialité » désigne la « structure de pouvoir » mise en place à partir de la conquête de ce qu’on appelle « l’Amérique latine » par les Européens, comme condition et mode éminent d’établissement du capitalisme, qui constitue « le mode de domination le plus général du monde contemporain ». Au cœur de cette « colonialité du pouvoir » se trouve une classification sociale eurocentrique de la population mondiale, selon des critères raciaux. En même temps, la thèse est formulée qu’un tel régime de domination s’installe dans la dimension constitutive du paradigme moderne de la raison – le binôme « rationalité/modernité ». Confronter la théorie critique de l’« École de Francfort » avec la question de la décolonialité permet de déplacer de manière décisive le centre de gravité de la répression de la nature interne, autour de laquelle se stabilise le sujet identique, à la répression que ce sujet exerce envers l’autre – à qui toute subjectivité est déniée et qui est au contraire assimilé à la nature externe. Odysseus sera remplacé par Cortés : les lignes d’une refonte de la préhistoire ( Urgeschichte ) de la subjectivité sont clairement offertes. Il s’agirait d’examiner de plus près le lien entre échange et violence, abstraction et domination, raison et domination, et de repenser la dialectique eurocentrée de l’ Aufklärung à la lumière de la conquête, c’est-à-dire de l’assujettissement des peuples indigènes, de ce qui allait devenir l’« Amérique » et de la traite des peuples africains. »
Boutroux historien de la philosophie

Published: November 2023

Avec les travaux de Boutroux (1845-1921), une nouvelle page est tournée dans la pratique de l’histoire de la philosophie comme exercice de la pensée philosophique : une histoire philosophante de la philosophie. Notre façon de faire de l’histoire de la philosophie, en citant les textes, en les situant, en analysant la structure des œuvres, en suivant les raisonnements pas à pas, lui est redevable. Ce n’est pas dans la critique qu’il est le meilleur, c’est dans la sympathie, voire dans la communion intellectuelle. Sa méthode est intuitive : il fait le portrait d’un penseur et montre les fils directeurs de son œuvre. Ainsi pour Aristote, Böhme, Descartes, Pascal, Leibniz.
Higher-order Randić index and isomorphism of double starlike trees
Authors: Su Zhenhua , Tang Zikai , Deng Hanyuan
Published: November 2023

For an integer $ h\geq 0 $, the $ h $th order Randić index for a simple graph $ G $ is defined as $ R^{h}(G) = \sum_{\pi}\frac{1}{\sqrt{v_1(\pi)v_2(\pi)\cdots v_{h+1}(\pi)}} $, where $ \pi $ extends over all paths of length $ h $ in $ G $ and $ v_i(\pi) $ denotes the degree of the $ i $-th vertex of the path $ \pi $. In this paper, we showed that the $ h $th order Randić index $ R^{h}(T) $ of a double starlike tree $ T $ (a tree with two vertices of degrees $ m_1, m_2 > 2 $) is completely determined by its branches of length $ \leq h $. As a consequence, we proved that the double starlike trees with equal $ h $-Randić index are isomorphic, except for some special values for $ m_1 $ and $ m_2 $.
Functionally Graded Steels Obtained via Electron Beam Powder Bed Fusion
Authors: Botero Carlos , Koptyug Andrey , Sjöström William , Jiménez-Piqué Emilio , Şelte Aydın , Rännar Lars Erik
Published: November 2023

Electron-Beam Powder Bed Fusion (EB-PBF) is one of the most important metal additive manufacturing (AM) technologies. In EB-PBF, a focused electron beam is used to melt metal powders in a layer by layer approach. In this investigation two pre-alloyed steel-based powders, stainless steel 316L and V4E, a tool steel developed by Uddeholm, were used to manufacture functionally graded materials. In the proposed approach two powders are loaded into the feeding container, V4E powder on top of 316L one, preventing their mixing. Such type of feeding yields components with two distinct materials separated by a zone with gradual transition from 316L to V4E. Microstructure and local mechanical properties were evaluated in the manufactured samples. Optical Microscopy, Scanning Electron Microscopy and EDX on the polished cross-sections show a gradual microstructural and compositional transition from characteristic 316L at the bottom of the specimens to the tool steel towards the top. Nanoindentation experiments confirmed a consequent gradient in hardness and elastic modulus, which gradually increase towards the top surface of the samples. The achieved results provide great possibilities to tailor the composition, microstructure, mechanical properties, and wear resistance by combining different powders in the powder bed AM technology. Potential applications include the tooling industry, where hard and wear-resistant materials are demanded on the surface with tougher and more ductile materials in the core of the tool.

A systematic review and meta-analysis of prevalence of seven psychiatric disorders in India
Authors: Dhiman Vikas , Menon Geetha R. , Tiwari Rajnarayan R.
Published: November 2023

Background:

After the National Mental Health Survey in 2016, multiple individual studies showed inconsistencies in the prevalence rates of psychiatric disorders in India. We performed a meta-analysis to estimate an up-to-date pooled estimate of the prevalence of depression, alcohol use disorder (AUD), anxiety disorder (AD), intellectual disability, suicidal attempt/death, autism, and bipolar disorder (BD) in India.

Materials and Methods:

We performed a systematic bibliographic search in Pub Med, Global Health Data Exchange (GHDx), and Google Scholar, along with a manual search for peer-reviewed epidemiological studies reporting the prevalence of depression, AUD, AD, MR, suicidal attempt/death, autism, and BD in India from January 1980 till March 2022. Adopting a random-effects model, we performed the meta-analysis using “MetaXL” software.

Results:

A total of 79 studies were included: depression (n = 28), AUD (n = 14), AD (n = 12), intellectual disability (n = 8), suicidal attempt/death (n = 7), autism (n = 6) and BD (n = 4). The pooled prevalence of depression and AUD was 12.4% (95% CI 9.4–15.9) (P < 0.001, I2 = 100%) and 21.5% (95% CI 14.1–30.0) (P < 0.001, I2 = 100%), respectively. AD, intellectual disability and suicidal attempt/death showed a prevalence of 11.6% (95% CI 8.1–15.7) (P < 0.001, I2 = 99%), 1% (95% CI 0.5–1.6) (P < 0.001, I2 = 98%) and 0.5% (95% CI 0.3–0.8) (P < 0.001, I2 = 100%), respectively. The meta-analysis in autism and BD showed pooled prevalence of 0.3% (95% CI 0.1–0.6) (P < 0.001, I2 = 96%) and 0.3% (95% CI 0.2–0.4) (P < 0.001, I2 = 78%), respectively. Subgroup analysis showed an increased prevalence of AD in the urban [24.3% (95% CI 3.7–52.9)] and younger [16.7% (95% CI 5.1–32.7)] population. The prevalence of depression and AD increased during the last two decades on decadal prevalence analysis.

Discussion:

The findings could be used for appropriate policy measures and guiding subsequent national mental health surveys.
Proton magnetic resonance spectroscopy-based evaluation of metabolic abnormalities in the right dorsolateral prefrontal cortex and caudate nucleus in treatment-naïve patients with obsessive-compulsive disorder

Published: November 2023

Background:

Obsessive-compulsive disorder (OCD) is a common psychiatric disorder whose underlying pathophysiology is insufficiently understood. The pathophysiology of OCD may be related to abnormalities in the biochemistry of neurotransmitters.

Aim:

The aim of the present study was to measure the absolute concentration of various metabolites in the right dorsolateral prefrontal cortex (DLPFC) and caudate nucleus (CN) in treatment-naive patients with OCD and compare it with healthy controls (HCs).

Methods:

The present study investigated the metabolic profile of two brain regions, namely right DLPFC and CN, by using single voxel in-vivo proton magnetic resonance spectroscopy (1H MRS) in drug-naive patients with OCD (n = 17, mean age = 30.71 ± 10.104 years) and compared it with healthy controls (n = 13, mean age = 30.77 ± 5.449 years). The patients with OCD were recruited after appropriate psychometric assessments. The 1H-MRS experiments were performed using the 3 Tesla (3T) human MR scanner, and absolute concentrations of metabolites were estimated using the LC model.

Results:

Significantly lower concentration of tNAA in the right DLPFC was observed in the patients with OCD compared to the controls, which may be indicative of neurodegeneration in this region. However, no significant differences were observed in the concentrations of the metabolites between the patients and controls in the CN region. The level of tNAA in DLPFC significantly correlated with the disability level (WHO-DAS) of the patients.

Conclusions:

The present study demonstrates abnormalities in the metabolic profile of an important region, DLPFC of the CSTC circuit, which is suggestive of neurodegeneration in the region in OCD patients.

Mood disorders are among the common mental disorders worldwide. Because of the persistence of cytomegalovirus (CMV) in the body and nervous system, this virus can be activated when the immune system is weakened and continues to exert its destructive effects throughout life. This study aimed to investigate the seroprevalence and association of human cytomegalovirus with mood disorders. Eligible articles were extracted using online international databases Science Direct, Medline, Web of Science, Scopus, and Google Scholar between 2000 and 2023. After quality assessment and specific inclusion and exclusion criteria, a total of eight eligible articles were included in the meta-analysis. Our finding showed that the seropositivity of CMV in mood disorders was 51.6% (95% CI; 42.8–60.4). There were statistical differences between mood disorders and control groups regarding the seropositivity of CMV 1.327% (95% CI; 13.27–10.45). The results of the publication bias using the Egger test confirmed no publication bias in each sub-group. The results of this meta-analysis study demonstrated that CMV infection might have associations with the incidence of mood disorders. Furthermore, we found that there were statistical differences between mood disorders and control groups regarding the seropositivity of CMV.
Symptoms of depression and anxiety and stress among postgraduate trainees in Sri Lanka: Risk factors and implications for practice
Authors: Alles Prasangika S. , Amarakoon Luckshika , Rohanachandra Yasodha M.
Published: November 2023

High workload, long working hours, and the need to study and work simultaneously put postgraduate trainee doctors at a high risk of depression, anxiety, and stress. A cross-sectional descriptive study was conducted among all postgraduate trainees registered at the Postgraduate Institute of Medicine (PGIM), Sri Lanka, using the 21-item Depression Anxiety Stress Scale (DASS-21). Eleven-point two percent (11.2%) had depressive symptoms, 8.9% had anxiety symptoms, and 1.9% had high levels of stress. Being female, having a past or current mental illness, not being supported by the trainers, being unfairly treated by trainers, dissatisfaction with the work environment, difficulty in coping with long working hours, and poor peer support were significantly associated with symptoms of depression and anxiety, and stress (P < 0.01). Given the association between psychological distress and the characteristics of training and work environment, the postgraduate training programs should be reviewed to ensure the psychological well-being of trainees.
Addressing a Threat to the Healthfulness of Tomorrow’s Generation: The Case of Cigarette Smoking in Nigeria
Authors: Egbe Catherine O. , Petersen Inge , Meyer-Weitz Anna
Published: November 2023

Cigarette smoking has widely received the attention of international and local health bodies. Efforts are being made towards curbing smoking prevalence globally with a view to reduce the health, economic and social effects of smoking in the society. While some developed countries are recording success in this effort mainly through stringent tobacco control policies and educating the public, Nigeria is yet to actively key into the WHO-Framework Convention on Tobacco Control (WHO-FCTC) which she signed in June 28 2004 (Nigeria: Report card on the WHO-FCTC, n.d.). With the stalling of the process of formulating a viable tobacco control policy in Nigeria through politics and politicking, it is important that other strategies which will help in reducing smoking prevalence especially among the youth be explored. This article looks at the psychosocial risk influences for smoking among Nigerian youth with a view to inform educational and psychosocial interventions that can help to reduce smoking uptake by the youth.
'Being Good' at Maths: Fabricating Gender Subjectivity
Authors: Chronaki Anna , Pechtelidis Yannis
Published: November 2023

Current research in mathematics education places emphasis on the analysis of men and women’s accounts about their life trajectories and choices for studying, working and developing a career that involves the learning and teaching of mathematics. Within this realm, the present study aims to highlight how mathematics, gender and subjectivity become interwoven by focusing the analysis on a single case study, that of Irene -a teacher in her early 40s. Based on how she articulates hegemonic discourses and narrates her relation to mathematics from the time she was a schoolgirl up till her recent work as teacher and her endeavours as participant in a professional development teacher training course, we argue how ‘mathematics’ becomes a mythical object for her subjectification. Irene as a female subject appropriates through her narrative the socially, culturally and historically constructed ideals about maths and gender and essentialises mathematical ability. Our study reveals how dominant discourses concerning ‘mathematics’ and ‘gender’ relate closely to subjectivity fabrication.
Joint Distributions in Probabilistic Semantics
Authors: Kozen Dexter , Silva Alexandra , Voogd Erik
Published: November 2023

Various categories have been proposed as targets for the denotational semantics of higher-order probabilistic programming languages. One such proposal involves joint probability distributions (couplings) used in Bayesian statistical models with conditioning. In previous treatments, composition of joint measures was performed by disintegrating to obtain Markov kernels, composing the kernels, then reintegrating to obtain a joint measure. Disintegrations exist only under certain restrictions on the underlying spaces. In this paper we propose a category whose morphisms are joint finite measures in which composition is defined without reference to disintegration, allowing its application to a broader class of spaces. The category is symmetric monoidal with a pleasing symmetry in which the dagger structure is a simple transpose.

Pearl's and Jeffrey's Update as Modes of Learning in Probabilistic Programming
Authors: Jacobs Bart , Stein Dario
Published: November 2023

The concept of updating a probability distribution in the light of new evidence lies at the heart of statistics and machine learning. Pearl's and Jeffrey's rule are two natural update mechanisms which lead to different outcomes, yet the similarities and differences remain mysterious. This paper clarifies their relationship in several ways: via separate descriptions of the two update mechanisms in terms of probabilistic programs and sampling semantics, and via different notions of likelihood (for Pearl and for Jeffrey). Moreover, it is shown that Jeffrey's update rule arises via variational inference. In terms of categorical probability theory, this amounts to an analysis of the situation in terms of the behaviour of the multiset functor, extended to the Kleisli category of the distribution monad.
A Categorical Framework for Program Semantics and Semantic Abstraction
Authors: Katsumata Shin-ya , Rival Xavier , Dubut Jérémy
Published: November 2023

Categorical semantics of type theories are often characterized as structure-preserving functors. This is because in category theory both the syntax and the domain of interpretation are uniformly treated as structured categories, so that we can express interpretations as structure-preserving functors between them. This mathematical characterization of semantics makes it convenient to manipulate and to reason about relationships between interpretations. Motivated by this success of functorial semantics, we address the question of finding a functorial analogue in abstract interpretation, a general framework for comparing semantics, so that we can bring similar benefits of functorial semantics to semantic abstractions used in abstract interpretation. Major differences concern the notion of interpretation that is being considered. Indeed, conventional semantics are value-based whereas abstract interpretation typically deals with more complex properties. In this paper, we propose a functorial approach to abstract interpretation and study associated fundamental concepts therein. In our approach, interpretations are expressed as oplax functors in the category of posets, and abstraction relations between interpretations are expressed as lax natural transformations representing concretizations. We present examples of these formal concepts from monadic semantics of programming languages and discuss soundness.

Semantics of multimodal adjoint type theory
Authors: Shulman Michael
Published: November 2023

We show that contrary to appearances, Multimodal Type Theory (MTT) over a 2-category M can be interpreted in any M-shaped diagram of categories having, and functors preserving, M-sized limits, without the need for extra left adjoints. This is achieved by a construction called "co-dextrification" that co-freely adds left adjoints to any such diagram, which can then be used to interpret the "context lock" functors of MTT. Furthermore, if any of the functors in the diagram have right adjoints, these can also be internalized in type theory as negative modalities in the style of FitchTT. We introduce the name Multimodal Adjoint Type Theory (MATT) for the resulting combined general modal type theory. In particular, we can interpret MATT in any finite diagram of toposes and geometric morphisms, with positive modalities for inverse image functors and negative modalities for direct image functors.

Implicative models of set theory
Authors: Maschio Samuele , Miquel Alexandre
Published: November 2023

In this paper we show that using implicative algebras one can produce models of set theory generalizing Heyting/Boolean-valued models and realizability models of (I)ZF, both in intuitionistic and classical logic. This has as consequence that any topos which is obtained from a Set-based tripos as the result of the tripos-to-topos construction hosts a model of intuitionistic or classical set theory, provided a large enough strongly inaccessible cardinal exists.
