A NICER Viewing Angle on the Accretion Stream of Vela X-1
Authors: Rahin Roi , Behar Ehud
Published: June 2023

Vela X-1 is the archetypal eclipsing high-mass X-ray binary, composed of a neutron star (NS) accreting the B-star wind. It was observed by nearly all X-ray observatories, often multiple times, featuring a rich spectrum of variable emission lines. However, the precise origin of these lines in the binary system remains uncertain. We perform a systematic, orbital-phase-dependent analysis of the reflected Fe Kα fluorescence line at 6.4 keV using over 100 NS Interior Composition Explorer observations. We resolve the line variability into 500 s time bins and find that it is predominantly due to variation in the ionizing flux, with a moderate underlying phase dependence over the 9-day orbital period. Our analysis reveals a significant reflection component that cannot originate from the companion B star alone. We also find that an appreciable portion of the B-star surface is obscured opposite the eclipse, and this obscuration is not symmetric around the midpoint (phase = 0.5). We argue that an accretion stream, from the B star to the NS and distorted by the orbital motion, is responsible both for the additional fluorescence emission component and for obscuring the B star.

Magnetic reconnection is a fundamental plasma process that has been studied with analytical theory, numerical simulations, in situ observations, and laboratory experiments for decades. The models that have been established to describe magnetic reconnection often assume a reconnection plane normal to the current sheet in which an antiparallel magnetic field annihilates. The annihilation points, also known as the X-points, form an x-line, which is believed to be perpendicular to the reconnection plane. Recently, a new study using Magnetospheric Multiscale mission observations has challenged our understanding of magnetic reconnection by providing evidence that the x-line is not necessarily orthogonal to the reconnection plane. In this study we report a second nonorthogonal x-line event with similar features as that in the previous case study, supporting that the sheared x-line phenomenon is not an aberrant event. We employ a detailed directional derivative analysis to identify the x-line direction and show that the in-plane reconnection characteristics are well maintained even with a nonorthogonal x-line. In addition, we find the x-line tends to follow the magnetic field on one side of the current sheet, which suggests an asymmetry across the current sheet. We discuss the possibility that the nonorthogonal x-line arises from an interplay between the two aspects of reconnection: the macroscopic magnetic field topology and microscopic particle kinetics.

We documented the nearshore ray-finned fishes in Puerto Morelos Reef National Park (PMRNP) by sampling 57 localities, including rocky intertidal pools, sandy bottoms, Thalassia beds, coral reefs, artificial reefs, karstic-slab bottoms, demersal-pelagic areas, and sessile-Sargassum patches. We recorded seven species new to Caribbean Mexican waters and one hundred and six species new to the PMRNP, most of which are small cryptobenthic reef fish. The resultant checklist includes 349 species, and specimens of 285 of which (81.7%) have been deposited in an ichthyological museum collection. These include both voucher organisms and with tissue samples for genetic analysis. A comparison with inventories at other localities of the Greater Caribbean indicates that more targeted sampling for cryptobenthic and deep-reef fishes is needed to provide a complete inventory. We also comment on the local use of some species as fishery resources.
Aggregating Users’ Online Opinions Attributes and News Influence for Cryptocurrencies Reputation Generation
Authors: Boumhidi Achraf , Benlahbib Abdessamad , Nfaoui El Habib
Published: June 2023

Reputation generation systems are decision-making tools used in different domains including e-commerce, tourism, social media events, etc. Such systems generate a numerical reputation score by analyzing and mining massive amounts of various types of user data, including textual opinions, social interactions, shared images, etc. Over the past few years, users have been sharing millions of tweets related to cryptocurrencies. Yet, no system in the literature was designed to handle the unique features of this domain with the goal of automatically generating reputation and supporting investors’ and users’ decision-making. Therefore, we propose the first financially oriented reputation system that generates a single numerical value from user-generated content on Twitter toward cryptocurrencies. The system processes the textual opinions by applying a sentiment polarity extractor based on the fine-tuned auto-regressive language model named XLNet. Also, the system proposes a technique to enhance sentiment identification by detecting sarcastic opinions through examining the contrast of sentiment between the textual content, images, and emojis. Furthermore, other features are considered, such as the popularity of the opinions based on the social network interactions (likes and shares), the intensity of the entity’s demand within the opinions, and news influence on the entity. A survey experiment has been conducted by gathering numerical scores from 827 Twitter users interested in cryptocurrencies. Each selected user assigns 3 numerical assessment scores toward three cryptocurrencies. The average of those scores is considered ground truth. The experiment results show the efficacy of our model in generating a reliable numerical reputation value compared with the ground truth, which proves that the proposed system may be applied in practice as a trusted decision-making tool.
A novel deep learning model with the Grey Wolf Optimization algorithm for cotton disease detection
Authors: Gülmez Burak
Published: June 2023

 Plants are a big part of the ecosystem. Plants are also used by humans for various purposes. Cotton is one of these important plants and is very critical for humans. Cotton production is one of the most important sources of income for many countries and farmers in the world. Cotton can get diseases like other plants and living things. Detecting these diseases is critical. In this study, a model is developed for disease detection from leaves of cotton. This model determines whether the cotton is healthy or diseased through the photograph. It is a deep convolutional neural network model. While establishing the model, care is taken to ensure that it is a problem-specific model. The grey wolf optimization algorithm is used to ensure that the model architecture is optimal. So, this algorithm will find the most efficient architecture. The proposed model has been compared with the ResNet50, VGG19, and InceptionV3 models that are frequently used in the literature. According to the results obtained, the proposed model has an accuracy value of 1.0. Other models had accuracy values of 0.726, 0.934, and 0.943, respectively. The proposed model is more successful than other models. 
The diatom genus Ulnaria (Bacillariophyta) in China
Authors: Liu Bing
Published: June 2023

This study deals with Ulnaria species found and described from two regions of China with large climate differences during the period of 2014–2022. The first region, located in the Wuling Mountains and Hunan province, has a subtropical climate and the second in Qinghai, a northwest province of China, has a highland continental climate which is characterized by a cold and long winter and warm, short summer. Previously there were nine new Ulnaria species published from the first region. This study describes 14 additional new Ulnaria taxa, nine of which were found in the first region and five of which were found in the second region. A key to the Ulnaria species that have been described from China is provided. The main morphological characteristics for 63 Ulnaria taxa are summarized in Appendices which allow the division of these Ulnaria taxa into three groups: the seven members of group one all possess both uniseriate striae and valve marginal spines, the 42 members of group two all possess uniseriate or mostly uniseriate striae but without the valve marginal spines, and the 14 members of group three all possess mostly biseriate striae and without valve marginal spines. To summarize the morphological characters of the published Ulnaria taxa and 14 taxa described in this study several conclusions for the characterization of Ulnaria are drawn: 1) each cell has two valve-appressed, long plate-like plastids; 2) living cells of many Ulnaria species often lie in girdle view on a slide because they have deep mantles and some copulae associated with either the epivalve or the hypovalve so that the cell depth is often larger than the valve width; 3) the basic structures forming a valve include sternum, virgae, and vimines/viminules; 4) the valvocopula is a closed hoop which has a similar ultrastructure in all Ulnaria taxa but differs from the other copulae in structure; 5) the configuration of girdle bands is a common condition; 6) the life history of Ulnaria can be divided into the four series of successive stages: auxospore, initial cell, pre-normal vegetative cell, and normal vegetative cell, which is very similar to the life history of Hannaea inaequidentata (Lagerstedt) Genkal and Kharitonov; 7) the closed valvocopula is proposed as a definition character for the genus Ulnaria because demonstrating all girdle bands closed is impracticable.
De la personnalité à la relation : un chemin de pensée et de pratique
Authors: Barrett-Lennard Godfrey T. , Alleaume Baptiste
Published: June 2023

Cet article postule pour la reconnaissance de la position centrale de la relation dans la vie des êtres humains en général, comme dans le cas particulier des thérapies centrées sur la personne et dans celui d’autres thérapies associées à cette mouvance. Les relations sont conceptualisées ici en tant qu’entités de processus émergents, qui développent leurs propres vies et présences. La thérapie est une relation parmi d’autres dans la vie d’un(e) client(e), chaque relation pouvant influencer d’autres systèmes interpersonnels dans l’expérience du client et toutes se situant dans des systèmes d’association plus larges. Une étude de cas détaillée aide à illustrer l’approche psycho-relationnelle et la pensée de l’auteur. Tout au long de son chemin cette cliente porte en elle des questions relationnelles concernant sa famille et sa vie quotidienne, questions qui se rejouent dans la relation de partenariat qui se développe et se déroule avec son thérapeute. Cette vision de la thérapie personnelle fait partie des niveaux de guérison proposés et qui sont nécessaires à tout l’éventail des systèmes d’association perturbés chez les êtres humains.
La thérapie centrée sur la personne est-elle une alternative radicale à la situation singulière et politique actuelle ou une révolution ratée ?
Authors: Markowitsch Susanna , Berthoud Laurent
Published: June 2023

L’Approche centrée sur la personne est réexaminée pour de possibles mises à jour dans les domaines dans lesquels je suis principalement impliquée : la psychothérapie, l’enseignement de la psychothérapie (tous deux en Autriche) et, plus généralement, la société d’aujourd’hui. L’adaptation de l’Approche centrée sur la personne au xxi e  siècle n’exige ni la modification ni l’amélioration de son concept originel, mais son ajustement à un monde en mutation de manière à susciter un soutien enthousiaste à son égard. Le succès de la thérapie centrée sur la personne est basé sur la compréhension de la conception de l’être humain, du paradigme de la « personne » et de l’idée de relation qu’il implique, en plus des présupposés de base souvent cités. L’Approche centrée sur la personne met l’accent sur une attitude interne comme base sur laquelle une coexistence harmonieuse dans la vie peut être construite. Rogers a qualifié l’Approche centrée sur la personne de révolution tranquille. Dans quel état se trouve la révolution qu’il a promue ? Est-elle trop silencieuse, ou reste-t-elle encore à commencer après tant d’années ? Comment pouvons-nous aider l’Approche centrée sur la personne immature à « grandir » et à assumer son identité singulière ? Je fais l’hypothèse que le problème ne réside pas seulement dans une idée erronée de ce qu’est la tolérance, mais aussi dans une réticence à se rendre visible en tant que personne, et que ce sont là des obstacles à une Approche centrée sur la personne plus largement diffusée et populaire.
Happy Unhappy Marriages in Rural Transylvania (1920s-1950s)
Authors: Bărbulescu Elena
Published: June 2023

Cet article vise à explorer les stratégies matrimoniales dans un village de Transylvanie au milieu de xx e siècle du point de vue des statuts sociaux et de richesse dans la communauté. Cette étude se concentre sur deux types de mariages – d’une femme et d’un homme – et deux stratégies qui s’y rattachent afin de préserver (pour l’homme) une richesse préexistante ou d’accéder (pour la femme) à plus de fortune et par conséquent à un statut social supérieur au sein de la communauté. Toute la communauté est de religion orthodoxe, et pratiquante à partir des années 1970, lorsqu’un nouveau prêtre arrivé dans le village a tout mis en œuvre pour faire de ses paroissiens de fidèles observants des rituels orthodoxes. Il est tout aussi important de noter que cette circulation matrimoniale se fait à l’intérieur d’un environnement préétabli – le village; tant d’un point de vue spatial que sur le plan social : il ne s’agit pas du mariage d’une jeune fille pauvre et d’un riche boyard, mais d’une pauvre paysanne avec un riche paysan voisin ou encore d’une riche paysanne avec un riche paysan. La méthodologie utilisera les items classiques de l’ethnographie pour l’interprétation qualitative des entretiens réalisés sur le sujet par l’auteure.
Septime Sévère conseruator orbis à Lepcis Magna et à Avenches
Authors: Christol Michel
Published: June 2023

Deux inscriptions, de Lepcis magna et d’Avenches, attribuent à Septime Sévère le titre de conseruator orbis . Elles sont immédiatement postérieures à la bataille de Lyon (197) qui lui donna la mainmise définitive sur l’empire. Ces documents ouvrent des perspectives sur la perception des grands événements durant la guerre civile, et sur la construction de l’image de Septime Sévère dans les années de conquête du pouvoir.
Appel à la conversion et controverses religieuses dans les écrits des auteurs chrétiens d’Afrique à l’aube du tournant constantinien
Authors: Nsiri Mohamed-Arbi
Published: June 2023

Chez les auteurs chrétiens du iii e et début iv e siècle, la critique des pratiques païennes tient une place très importante. Ces attaques sont, en effet, si abondantes que l’on ne peut manquer de s’interroger sur les raisons de cette profusion. Ce thème apparaît ainsi comme une composante organique des œuvres des auteurs chrétiens d’Afrique à l’aube de la paix constantinienne. Ces auteurs avaient construit leur appareil argumentatif à partir d’une observation minutieuse de la réalité socio-culturelle de leur société. Leurs écrits sont donc un élément fondamental pour comprendre le début de la construction d’une mouvance antipaïenne à l’intérieur de la société africaine de l'époque romaine tardive.
La philosophie de l’histoire de Vico dans un tableau de Jean Gigoux (1837-1838)
Authors: Eleanor Signorini Anna
Published: June 2023

L’article aborde plusieurs thématiques de l’histoire sociale de l’art dans la première moitié du xix e siècle en France à travers l’analyse d’un tableau peu connu de Jean Gigoux sur Cléopâtre : la réception de l’Antiquité gréco-romaine et égyptienne (grâce aussi au voyage du peintre en Italie), la peinture d’histoire et la philosophie de l’histoire de Giambattista Vico. La grande toile (disparue) Antoine et Cléopâtre après la bataille d’Actium essayant des poisons sur des esclaves (1837-1838) est analysée comme mise en application picturale des théories de Vico dans La Scienza Nuova et comme exaltation des racines gauloises de la civilisation française.

La thérapie par l’intégration du cycle de vie (ICV) : une thérapie de la réappropriation de soi
Authors: Bajramovic Richet Ana , Duriez Nathalie
Published: June 2023

La thérapie par l’intégration du cycle de vie (ICV) est un dispositif de soins récent dont l’efficacité doit être évaluée. Est-ce qu’en revisitant le passé, le patient parvient à une réappropriation de son soi ? Nous explorerons cette question à partir de l’évaluation de la thérapie de Fabien. Selon le paradigme du Change Process Research , nous avons interrogé ce patient à l’issue de la thérapie. En croisant ces données et celles provenant du thérapeute-chercheur, nous pouvons décrire des changements dans les cinq dimensions du rétablissement personnel : être en relation, l’espoir pour le futur, le sentiment d’identité, donner du sens à la vie et être acteur de sa vie (Leamy et al., 2011).
Image du corps et registre de l’imaginaire dans un cas de psychose infantile
Authors: Dellanoce Filippo
Published: June 2023

L’auteur interroge la constitution du registre de l’imaginaire dans le cadre d’un cas de psychose infantile, et selon la théorie de Jacques Lacan, Gisela Pankow et Marie Couvert. L’observation clinique initiale montre que l’unité imaginaire du moi semble être problématique chez le patient et, par conséquent, l’assomption de la différence au niveau de la pensée résulte impossible. Le travail des consultations – qui prend la forme d’une mise en scène du monde fantasmatique de l’enfant à l’aide d’un support technique spécifique (pions en bois avec uniquement des yeux) – amène d’abord le patient à dessiner volontairement son autoportrait : il semble ainsi pouvoir conquérir la reconnaissance de la forme du corps humain. Ensuite, en mettant en scène une histoire apportée par le patient et en masquant les pions qui représentent les personnages, on réalise une mascarade : le patient commence à jouer non seulement avec l’imaginaire, mais aussi avec le symbolique. Enfin, suite à la représentation d’une scène d’angoisse avec un serpent, le patient dessine spontanément son image à côté de celle d’une petite fille : la reconnaissance de l’image unique de son corps, en tant que corps sexué, semble avoir été obtenue.

Quelle transition vers la majorité pour les ados en institution ? Articulation entre diachronie et synchronie
Authors: Nyssens Grégoire , Casale Marilena , De Boever Stéphanie
Published: June 2023

Pour les adolescents placés en institution sous mandat judiciaire, le passage vers la majorité à 18 ans réactive des enjeux de séparation et d’autonomie puisque cela correspond à la levée du mandat. Ces enjeux sont soutenus par l’élan vital qui ouvre vers l’avenir avec une soif de liberté après l’aide contrainte des années de placement. Mais ces enjeux sont aussi freinés par des angoisses de pertes, de ruptures, d’abandon ou de répétition. Ces angoisses apparaissent à travers les symptômes du temps arrêté comme le blocage des démarches à faire, la régression des besoins affectifs ou la répétition des troubles du comportement. Notre projet pilote tente la mise en place d’une structure de transition vers l’autonomie pour les jeunes de 17 à 23 ans placés en institution pour favoriser ce passage à la majorité, sans rejouer les ruptures qui ont parsemé les années d’enfance avec les risques de répétition de l’histoire familiale et pas seulement de régression individuelle et de sans-abrisme. Le temps vécu est donc au travail.

Objectives:

To describe multimodal imaging findings of vitamin A deficiency retinopathy.

Methods:

A retrospective study of patients with serum retinol < 0.3 mg/L. Fundus color photos, spectral domain-optical coherence tomography (SD-OCT), and fundus autofluorescence (FAF) were reviewed and, when available, electrophysiological tests were analyzed.

Results:

Forty-five eyes (63.9 ± 15.7 years) were included. Ultra-widefield fundus photography showed drusen-like deposits (53.3%) and macular retinal pigment epithelium (RPE) mottling (40%). The deposits were hypoautofluorescent, and a perifoveal hyperautofluorescent ring was present in 8.9%. By SD-OCT, the ellipsoid zone had an irregular appearance (100%) and conical deposits anterior to the RPE (33.3%). Electroretinogram (ERG) (66.7%) showed a decrease in b-wave in the scotopic registers, and microperimetry (4.4%) showed decreased foveal sensitivity. After vitamin A supplementation, SD-OCT and FAF showed resolution of all findings. Forty percent of eyes had restoration of the scotopic registers in ERG and improved macular sensitivity by microperimetry (4.4%).

Conclusions:

Vitamin A deficiency causes a mild cone dysfunction in addition to the more severe absent rod response.

Near-Complete Drusen Resolution With Brolucizumab: A Mechanism for Proinflammatory Mediated Drusen Clearance?
Authors: O'Riordan Matthew , Hudson Natalie , O'Callaghan Jeffrey , Campbell Matthew , Cahill Mark
Published: June 2023

A 68-year-old woman with macular drusen was diagnosed with neovascular age-related macular degeneration (AMD) and treated with intravitreal brolucizumab. She had a good response to treatment with reduced height of the pigment epithelial detachment, and a good visual outcome. Remarkably, she had a near-complete resolution of macular drusen, yet this was accompanied by the development of anterior uveitis. We propose a proinflammatory-based mechanism for the brolucizumab-induced drusen resorption. Identifying the biochemical pathways responsible could hold the potential to discover novel forms of therapy for the treatment of AMD.

La defensa de las mujeres en la España ilustrada: la pieza grande de Jappelli en la Real Casa del Labrador de Aranjuez
Authors: Cobo Delgado Gemma
Published: June 2023

La pintura de la bóveda de la Pieza Grande de Jappelli en la Real Casa del Labrador de Aranjuez ha pasado desapercibida y precisa de un estudio en profundidad, ya que es el único ejemplo conocido de transferencia del discurso ilustrado de la defensa de las mujeres a la pintura y se encuentra además en un lugar privilegiado, pues la corte de Carlos IV y María Luisa de Parma pasaba allí seis meses al año. En la bóveda se plasmaron visualmente argumentos similares a los que Feijoo utilizó en su famoso ensayo “Discurso en defensa de las mujeres” publicado en 1726: se toman referencias de mujeres míticas y otras de la historia reciente y contemporánea para demostrar su capacidad para el entendimiento y sus aptitudes para las artes.
Sufrágio feminino e feminismo na imprensa brasileira da Parahyba, 1913-1933: rebeldia ou conformação?
Authors: Machado Charliton José dos Santos , Vieira Cristina Maria Coimbra , Nunes Maria Lúcia da Silva , Fialho Lia Machado Fiuza
Published: June 2023

O artigo trata das reivindicações das mulheres por direitos políticos e educacionais em meio ao contexto socio-histórico de exclusão feminina da vida pública de 1913 a 1933. O objetivo é o de compreender como o debate em prol do sufrágio feminino e do feminismo era abordado na imprensa da Parahyba do Norte nas primeiras décadas do século XX. Desenvolveu-se uma pesquisa documental no jornal A União, que localizou quinze edições, veiculadas nos anos de 1913, 1920, 1925, 1930, 1931 e 1933, que destacam essa temática. A análise revelou que o debate das ideias feministas não era uníssono, pois algumas vezes havia contradições entre o desejo de conquistar maior escolaridade, independência financeira e direitos políticos e o medo de ferir os padrões e ideologias vigentes ao ultrapassar a esfera da vida privada dedicada à família.
Le nudge comme incitation aux mobilités alternatives, une analyse technopolitique
Authors: FOURNIER Anne , Labour Michel , LISSARRAGUE Nicolas , LELEU-MERVIEL Sylvie
Published: June 2023

Les nudges appliqués à la mobilité des individus alimentent un nombre croissant d’expérimentations de terrain. Le présent article présente le concept de nudge, puis propose un état de l’art de la bibliographie et une classification des principaux biais cognitifs sur lesquels les nudges s’appuient pour modifier une architecture de choix. La deuxième partie de l’article présente les conflits de rationalités et la négociation qui en résulte dans le fil de la conception d’un jeu de nudges dédié aux changements de comportements en termes de mobilité, jeu destiné à s’insérer dans une application de téléphone multifonctions.Au-delà des approches définitionnelles et de la production de nudges originaux, ce qui importe ici est de distinguer, en théorie et en pratique, les divers leviers à partir desquels une incitation peut se mettre en place, et comment les technologies de l’information et de la communication (TIC) peuvent être mobilisées pour tenter d’influer sur les comportements. Articulant les perspectives de l’économie comportementale, des sciences de l’information et de la communication et des sciences cognitives, la recherche s’inscrit dans une analyse technopolitique de fond.

Student Satisfaction and Academic Success With Mentoring
Authors: Flores Alberto M.
Published: June 2023

In an increasingly competitive world, many universities have tried to improve academic performance, retention, and graduation rates by introducing online education or mentoring. Although researchers have explored university mentoring using qualitative methods, few have addressed the quantitative connection between student mentoring and academic performance. Four separate regression analyses using ordinary least squares (OLS) methodology for the continuous outcome variable SAP and binary logistic methodology for the binary outcome variable OTP, were performed on 19,869 responses to a survey. Positive linear relationships were found between both predictor variables and SAP. A positive relationship was found between satisfaction with the university and OTP; however, satisfaction with mentoring was not a predictor of OTP. The results of this study provided information based on quantitative analysis about the relationship between student satisfaction and student academic performance outcomes.
Teacher and Student Perspectives on Creativity in Pop Music Education
Authors: Wei Lai
Published: June 2023

Pop music education has become a new field in music education. Considering this, the short history of pop music in China makes it difficult to construct a comprehensive education system for this genre of music. Though creativity has become one of the most important elements discussed by music educators, there are insufficient references to creativity in pop music education. Therefore, this research explores teachers' and students' perspectives on the development of student creativity in pop music education at the Sichuan Conservatory of Music (SCM), a professional institution that established the first pop music department in China. Employing a qualitative approach, data from in-depth interviews with both teachers and students were analyzed. Findings demonstrated two main issues: a lack of professional faculty and insufficient academic events. This chapter proposes the improvement of academic conditions, including professional development opportunities and teaching modes to address issues of creativity in Chinese pop music education.

Black and Brown students are traditionally reported as lagging behind in academic performance, and there is concern that this status may lead to their exclusion from STEM programs and thus limit their ability to participate in a program that leads them to higher academic achievement with an inroad to higher education and higher financial rewards in a profession that is high yielding, not only in the USA, but the across the globe. The chapter highlights how three mentoring programs support Black high school students to do STEM, including collaborations between STEM professionals and students, a summer camp, and an after-school program. It includes curricula to influence students' interest in STEM. Recommendations for program revisions include e-mentoring, hosting workshops in central locations, and incorporating reflections after workshops to improve session quality.

Authors: Manda Vijaya Kittu , Nihar Lubza K.
Published: June 2023

Governments and market regulators are debating and deliberating on matters of concern and benefits of treating cryptocurrencies as an asset or a currency so that they can tax them accordingly. 2022 has shaken the financial markets with the onset of the worst crypto winters in cryptocurrency history on one hand and the collapse of a few cryptocurrencies and the exchanges that facilitate investing and trading in them. These events brought chills to the stakeholders, who began questioning the stability of the cryptocurrency and the functioning of various exchanges. Cryptocurrencies promise to be the future of currency, and hence, there is an immediate need to protect investors by regulating them – especially those cryptocurrency exchanges running in a centralized form. The case examines the collapse of FTX and other financial institutions because they exposed the structural weaknesses existing in the system. The case also examines competitor business strategies to protect themselves from such incidents and stresses the need for governmental and regulatory interventions.

Authors: Shalender Kumar , Sharma Naman
Published: June 2023

The role, importance, and significance of innovation can't be overemphasized in this day and age. While innovators would like to work beyond constraints, the enhanced importance of using resources efficiently is fast fuelling the prospects of disciplined innovation in companies across industries. Studies have shown that the presence of constraints and limits actually spur innovation and can prove instrumental in guiding organisations towards enhanced profitability and greater market share. Using real-world case studies, this research emphasized the importance of disciplined innovation and proposed a framework to integrate this characteristic into the functional procedures and operational mechanisms of the company. The findings of the research suggest that constraining the creativity of innovators within the broader framework of accountability is the optimum approach towards achieving a perfect balance between creativity, innovation, and resource consumption to deliver superior customer experiences.

The use of continuous positive airway pressure (CPAP) in COVID-19 hypoxemic respiratory failure (h-ARF) under a strict protocol has been described to be highly efficient. However, early prediction of failure is crucial to avoid delayed intubation. Lower PaCO2 values may represent a higher inspiratory effort and, therefore, may help identify patients at greatest risk of CPAP failure. Aim of this study was to observe the PaCO2 trend of COVID-19 patients with h-ARF before and after the initial treatment with helmet-CPAP. A case series study was conducted from November 2020 to March 2021. All adult patients with h-ARF secondary to COVID-19 treated with helmet-CPAP and eligible for endotracheal intubation were observed. Of a total of 54 patients, 32 (59.3%) underwent intubation. Seven (12.9%) patients died in the ETI group, and none in the non-ETI group. Median PaO2/FiO2 ratio on admission was 91mmHg [IQR 68-185] vs. 104mmHg [IQR 85-215] (p=0.137) in the ETI e non-ETI group, respectively. No differences were found either for PaCO2 values on admission (31.5mmHg [IQR 27-35] vs. 29.3mmHg [IQR 27.7-40]) and for PaCO2 variations after 120 minutes of CPAP (+2.38mmHg ± 3.65 vs. +2.73mmHg ± 3.96). Changes in PaCO2 values were observed during an initial helmet-CPAP trial, but no differences were found in those undergoing endotracheal intubation as compared to the others.

Published: June 2023

A 60-year-old man presented with a 2-week history of progressive dyspnea and bilateral leg edema. He had undergone a prosthetic mitral valve replacement 9 years earlier. The patient was in respiratory distress (respiratory rate 32/min, oxygen saturation 86% on air, heart rate 124/min, blood pressure 109/56 mmHg). Examination revealed bilateral lung crackles and reduced air entry with dullness to percussion and elevated jugular venous pressure. The electrocardiogram showed sinus tachycardia. A chest X-ray (CXR) (Figure 1) and bedside lung ultrasonography were performed (Figure 2A). A diagnosis of a large pleural effusion was made and urgent thoracocentesis was considered in view of the patient’s respiratory distress. A repeat ultrasonographic scan with adjusted angulation to identify the most suitable entry point for the chest drain (Figure 2B) yielded new results that led to the cancellation of the thoracocentesis.
The murder of a psychiatrist in Italy raises problems for all of us
Authors: Fraticelli Carlo
Published: June 2023

The brutal murder of 55-year-old Italian psychiatrist Barbara Capovani in April 2023, at the hands of a man she had assisted during a hospitalization four years prior, produced a wave of emotion within Italian psychiatry, with important echoes in the media. It is the death of a woman at work, a doctor, a psychiatrist, a professional of the National Health Service who has been taking care of serious mental illnesses for years. She was beaten to death by the attacker at the end of her shift at the psychiatric ward of the Santa Chiara Hospital in Pisa as she was untying her bicycle to go home. The man is now in jail on premeditated murder accusations. The day before he had gone to look for her in the hospital without success; the day of the crime he returned, dressed in dark clothes, masked with a hat on his head and a backpack on his shoulders. During his arrest, officers discovered a crossbow and some bolts in his home.
Cold-Water Immersion and Lower Limb Muscle Oxygen Consumption as Measured by Near-Infrared Spectroscopy in Trained Endurance Athletes
Authors: Jones Ben , Waterworth Sally , Tallent Jamie , Rogerson Mike , Morton Chris , Moran Jason , Southall-Edwards Rob , Cooper Chris E. , McManus Chris
Published: June 2023

Context

Cold-water immersion (CWI) has been reported to reduce tissue metabolism postimmersion, but physiological data are lacking regarding the muscle metabolic response to its application. Near-infrared spectroscopy (NIRS) is a noninvasive optical technique that can inform muscle hemodynamics and tissue metabolism.

Objective

To investigate the effects of CWI at 2 water temperatures (10°C and 15°C) on NIRS-calculated measurements of muscle oxygen consumption (mVO2).

Design

Crossover study.

Setting

University sports rehabilitation center.

Patients or Other Participants

A total of 11 male National Collegiate Athletic Association Division II long-distance runners (age = 23.4 ± 3.4 years, height = 1.8 ± 0.1 m, mass = 68.8 ± 10.7 kg, mean adipose tissue thickness = 6.7 ± 2.7 mm).

Intervention(s)

Cold-water immersion at 10°C and 15°C for 20 minutes.

Main Outcome Measure(s)

We calculated mVO2 preimmersion and postimmersion at water temperatures of 10°C and 15°C. Changes in tissue oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb), total hemoglobin (tHb), hemoglobin difference (Hbdiff), and tissue saturation index (TSI %) were measured during the 20-minute immersion at both temperatures.

Results

We observed a decrease in mVO2 after immersion at both 10°C and 15°C (F1,9 = 27.7801, P = .001). During the 20-minute immersion at both temperatures, we noted a main effect of time for O2Hb (F3,27 = 14.227, P = .001), HHb (F3,27 = 5.749, P = .009), tHb (F3,27 = 24.786, P = .001), and Hbdiff (F3,27 = 3.894, P = .020), in which values decreased over the course of immersion. Post hoc pairwise comparisons showed that these changes occurred within the final 5 minutes of immersion for tHb and O2Hb.

Conclusions

A 20-minute CWI at 10°C and 15°C led to a reduction in mVO2. This was greater after immersion at 10°C. The reduction in mVO2 suggests a decrease in muscle metabolic activity (ie, O2 use after CWI). Calculating mVO2 via the NIRS-occlusion technique may offer further insight into muscle metabolic responses beyond what is attainable from observing the NIRS primary signals.
