We present the PANORAMIC survey, a pure parallel extragalactic imaging program with JWST/NIRCam observed during Cycle 1. The survey obtained ∼530 square arcmin of NIRCam imaging from 1–5 μm, totaling ∼192 hr of science integration time. This represents the largest on-sky time investment of any Cycle 1 GO extragalactic NIRCam imaging program by nearly a factor of 2. The survey includes ∼432 square arcmin of novel sky area not yet observed with JWST using at least six NIRCam broadband filters, increasing the existing area covered by similar Cycle 1 data by ∼60%. Additionally, 70 square arcmin was also covered by a seventh filter (F410M). A fraction of PANORAMIC data (∼200 square arcmin) was obtained in or around extragalactic deep fields, enhancing their legacy value. Pure parallel observing naturally creates a “wedding cake” survey with both wide and ultra-deep tiers, with 5σ point-source depths at F444W ranging from 27.8–29.4 (ABmag), and with minimized cosmic variance. The ≳6-filter strategy yields remarkably good photometric redshift performance, achieving similar median scatter and outlier fraction as CANDELS (σ
NMAD ∼ 0.07; η ∼ 0.2), enabling a wealth of science across redshift without need for follow-up or ancillary data. We overview the proposed survey, the data obtained as part of this program, and document the science-ready data products in the data release. PANORAMIC has delivered wide-area and deep imaging with excellent photometric performance, demonstrating that pure parallel observations with JWST are a highly efficient observing mode that is key to acquiring a complete picture of galaxy evolution from rare bright galaxies to fainter, more abundant sources across redshifts.
On the Formation of Planets in the Milky Way’s Thick Disk
Authors: Hallatt Tim , Lee Eve J.
Published: January 2025

Exoplanet demographic surveys have revealed that close-in (≲1 au) small planets orbiting stars in the Milky Way’s thick disk are ∼50% less abundant than those orbiting stars in the Galactic thin disk. One key difference between the two stellar populations is the time at which they emerged: thick-disk stars are the likely product of cosmic noon (redshift z ∼ 2), an era characterized by high star formation rate, massive and dense molecular clouds, and strong supersonic turbulence. Solving for the background radiation field in these early star-forming regions, we demonstrate that protoplanetary disks at cosmic noon experienced radiation fields up to ∼7 orders of magnitude more intense than in solar neighborhood conditions. Coupling the radiation field to a one-dimensional protoplanetary disk evolution model, we find that external UV photoevaporation destroys protoplanetary disks in just ∼0.2–0.5 Myr, limiting the timescale over which planets can assemble. Disk temperatures exceed the sublimation temperatures of common volatile species for ≳Myr timescales, predicting more spatial homogeneity in gas chemical composition. Our calculations imply that the deficit in planet occurrence around thick-disk stars should be even more pronounced for giant planets, particularly those at wide orbital separations, predicting a higher rocky-to-giant planet ratio in the Galactic thick disk versus thin disk.

Published: January 2025

The cosmic X-ray background (CXB) is dominated by the obscured and unobscured coronal light of active galactic nuclei (AGN). At energies below 10 keV, the CXB can be well explained by models taking into account the known AGN and the observed distribution of their obscuring, line-of-sight column densities, N
H,l.o.s. However, at energies around the Compton reflection hump (~30 keV), the models fall short of the data. This suggests the existence of a population of as yet undetected Compton-thick (CT) AGN (N
H,l.o.s > 1.5 × 1024 cm−2) whose X-ray spectra are dominated by the light that has been reprocessed by the obscuring material. In this work, we continue the effort to find and catalog all local (z < 0.05) CT AGN. To this end, we obtained soft X-ray data with Chandra for six local BAT detected sources lacking ROSAT (0.1–2.4 keV) counterparts, indicating potential obscuration. We fit their spectra with Bayesian and least squares methods using two different models, borus02 and UXCLUMPY. We compare the results of the different models and methods and find that the N
H,l.o.s is consistently measured in each case. Three of the sources were also observed with XMM-Newton, allowing the opportunity to search for variability in soft X-ray flux or N
H,l.o.s. From this sample, we find one strong CT candidate (NGC 5759) and one weaker CT candidate (CGCG 1822.3+2053). Furthermore, we find tentative evidence of N
H,l.o.s variability in 2MASX J17253053–4510279, which has N
H,l.o.s < 1022 cm−2.
L’utilisateur, acteur de la régulation des données
Authors: Falque-Pierrotin Isabelle
Published: January 2025

Depuis le 25 mai 2018, l’Union européenne dispose d’un socle juridique rénové sur la régulation des données personnelles, le Règlement général sur la Protection des Données (RGPD). Ce nouveau cadre a été pensé selon l’objectif ambitieux de replacer les utilisateurs dans l’« équation » de la promesse numérique. Cette intervention du législateur européen était plus qu’opportune. En l’espace de quelques décennies, et alors même que les données personnelles prenaient une place économique et sociétale croissante, l’individu a en effet eu un sentiment croissant de dépossession, de malaise face à cet écosystème numérique complexe. Si l’Internet s’est construit autour de l’émancipation des personnes, les failles de sécurité ou les scandales qui se succèdent relatifs à l’utilisation des données personnelles, renforcent à l’inverse l’impression que nous évoluons dans une infrastructure aux bases fragiles et contestables, où l’individu n’est plus vraiment le maître à bord. En permettant une meilleure maîtrise des individus sur leur vie numérique, le RGPD constitue une étape cruciale pour replacer l’utilisateur au cœur de ce « récit » du numérique. Il lui confère une souveraineté jusqu’ici inégalée sur ses données ; il l’outille pour retrouver son libre arbitre dans cet univers. Par ce Règlement, le droit réussit l’exploit d’épouser les pratiques numériques du XXI e siècle tout en réaffirmant des valeurs fondamentales ancrées dans l’humanisme européen. Les mois à venir vont être cruciaux. En donnant vie et opérationnalité au Règlement, utilisateurs, entreprises et régulateurs seront comptables du résultat. Éviter la dépossession numérique reste un défi en constante négociation, à l’heure où les grandes régions du monde s’affrontent sur la souveraineté du numérique, à l’heure où les moyens d’analyse de données continuent à se perfectionner, l’intelligence artificielle figurant en tête des enjeux.
Plan France Très Haut Débit : une gouvernance originale entre État, collectivités et opérateurs
Authors: Heude Ghislain
Published: January 2025

Exemple d’une politique industrielle co-construite entre État, opérateurs et collectivités, le Plan France Très Haut Débit (PFTHD) lancé en 2013 doit aboutir à une couverture intégrale du territoire national en très haut débit dans un délai de dix ans. Dans sa conception, ce plan a dû composer avec un cadre existant mobilisant une variété d’acteurs (personnes publiques, opérateurs privés, investisseurs et équipementiers…) et d’échelons territoriaux. Ne partant donc pas d’une feuille blanche, le Plan France Très Haut Débit a cherché à transformer cette complexité initiale en atout en s’appuyant notamment sur un modèle de gouvernance originale.
La technologie, menace ou levier de la conduite du changement ?
Authors: Chalchat Constance
Published: January 2025

Pendant plus d’un siècle, nous avons peu à peu robotisé les organisations, en découpant nos chaînes de valeur en tâches simples et en optimisant ces dernières. Alors que les robots font aujourd’hui partie intégrante de notre quotidien, nous devons aider les collaborateurs à regagner en humanité, en s’appuyant sur des qualités uniques : empathie, créativité, capacité à résoudre des problèmes complexes. Car qui peut être meilleur robot qu’un robot ? La valeur ajoutée de collaborateurs plus humains doit nous permettre de réinventer les chaînes de valeur en redistribuant les rôles. Il faut pour cela revoir radicalement la façon dont nous recrutons et manageons, pour nous doter des compétences nécessaires qui feront de l’humanité le facteur de différenciation du futur.
La conduite automatisée, intelligences artificielles et humaines, quelles interactions ?
Authors: Lafay Antoine , Devauchelle Guillaume
Published: January 2025

Le rapport de l’homme à la conduite automobile est complexe et dépasse le simple usage d’un objet technologique. L’introduction de l'intelligence artificielle (IA) ouvre des perspectives sans précédent et pose une nouvelle fois la question de la compréhension et de l’acceptabilité des nouvelles technologies. Les auteurs décrivent le déploiement progressif de la conduite automatisée, l’état de l’art actuel et les technologies mises en œuvre, puis analysent les perspectives et les défis à relever. Défis technologiques bien sûr, mais il faudra aussi réinventer une nouvelle mobilité. Que fera-t-on du temps, aujourd'hui perçu comme confisqué par des tâches de conduite peu intéressantes dans la circulation actuelle ?
Cuire des tuiles en France, 13 e -19 e siècles. Crise de ressources et innovation technique
Authors: Lacheze Cyril
Published: January 2025

Un four à tuiles, en France, nécessitait jusqu’au début du 20 e s. des apports considérables de bois, alors que le pays était marqué par la déforestation. Des mesures de préservation furent prises dès le 16 e s. Dans certaines régions, les tuiliers ont dû s’adapter, notamment en remplaçant le bois par de la houille. Cette crise a également créé des opportunités pour les propriétaires de couvert forestier : ceux-ci ont moins cherché à protéger les ressources en bois qu’à profiter de la crise pour en taxer l’utilisation. Une autre possibilité était l’innovation, avec des fours plus économes. Un grand nombre de brevets ont été déposés à cet effet au 19 e s., conduisant au développement de fours continus encore utilisés aujourd’hui.
Approaching the Council of the EU and Member States’ Permanent Representations as ethnographic field sites

Published: January 2025

Qu’est ce que la démarche ethnographique permet d’entrevoir du processus décisionnel du Conseil de l'UE ? Cet article explore comment les méthodes ethnographiques contribuent à l'étude de la prise de décision au Conseil, en s'appuyant sur une revue de travaux ethnographiques récents, ainsi que sur les conclusions d’un travail d’observation participante au sein d’une représentation permanente. Après être revenu sur les difficultés méthodologiques propres à l’approche ethnographique, l’article souligne deux pistes prometteuses pour de futures recherches sur le Conseil et les représentations permanentes, dont l’étude des pratiques de négociation et des dynamiques de pouvoir interinstitutionnelles européennes.
Les « intermittents » de la représentation d’intérêts du secteur portuaire : des acteurs à la porte du Parlement européen et du Conseil de l’Union européenne ?
Authors: Kerduel Carole
Published: January 2025

Cet article s’interroge sur les logiques d’accès des groupes d’intérêts aux institutions européennes. Relevant d’une démarche ethnographique fondée sur la participation de son auteure aux négociations de la proposition du règlement « services portuaires » en tant que lobbyiste, il entend approfondir la connaissance des pratiques des représentants d’intérêts du pôle « intermittent » du champ de l’eurocratie (Georgakakis, 2012), c’est-à-dire des acteurs investissant occasionnellement l’espace administratif et politique européen, et dont les ressources et les pratiques sont peu ajustées à cet espace par rapport à ceux du pôle « permanent », davantage socialisés au fonctionnement des institutions européennes. L’hypothèse développée ici est que leurs pratiques de lobbying, et tout particulièrement les conditions et les modalités de leur accès aux acteurs administratifs et politiques du Parlement européen (PE) et du Conseil de l’Union européenne (Conseil de l’UE), sont dépendantes de leur positionnement dans l’espace administratif et politique européen en tant qu’« intermittents ».
Tractional Retinoschisis in Proliferative Diabetic Retinopathy Imaged With Swept-Source Optical Coherence Tomography Angiography
Authors: Rohowetz Landon J. , Iyer Prashanth G. , Ashkenazy Noy , Fan Kenneth C. , Laiginhas Rita , Shi Yingying , Liu Jeremy , Rosenfeld Philip , Flynn Harry W.
Published: January 2025

Tractional retinoschisis (TRS) secondary to proliferative diabetic retinopathy (PDR) may be differentiated from tractional retinal detachment (TRD) by its characteristically nonprogressive course. The purpose of the current study was to describe the use of swept-source optical coherence tomography angiography (SS-OCTA) in the diagnosis and monitoring of TRS secondary to PDR. Retrospective, consecutive case series of patients with TRS secondary to PDR are featured. Clinical notes, fundus photography, and SS-OCTA images are reviewed. The study comprised three eyes of three patients with PDR and TRS. Visual acuity and anatomic features on SS-OCTA were stable in all patients at one year or more of follow-up. Tractional retinoschisis secondary to PDR is typically nonprogressive and may be observed without surgery. SS-OCTA serves as a noninvasive and effective imaging tool to distinguish TRS from TRD and to demonstrate anatomic stability over time.

Published: January 2025

Background and Objective

Sickle cell disease (SCD) is a vascular disease that may affect the retina. This study aimed to evaluate differences in average velocity (AV, mm/s), blood flow (BF, μL/min) and vessel diameter (VD, μm) from the temporal retinal arcades in SCD compared to healthy eyes using Doppler optical coherence tomography (DOCT).

Patients and Methods

A cross-sectional study was conducted between 2021 and 2023. The DOCT scan was located at the superior and inferior temporal vessel arcades of all subjects. Differences between the two groups were assessed.

Results

Thirty-nine healthy eyes and 36 SCD eyes were imaged. The median of AV, BF, and VD were 1.4, 2.5, and 1.3 times higher in SCD eyes compared to healthy eyes in the superotemporal arteries (
P
= 0.002,
P
= 5.0 × 10–3,
P
= 4.0 × 10–6, respectively). Similar findings were observed for superotemporal veins and inferotemporal veins.

Conclusion

Eyes with SCD eyes exhibited significantly elevated retinal vascular flow parameters compared to healthy eyes.

Outcomes of Intravitreal Aflibercept 8 mg in Eyes With Neovascular Age-Related Macular Degeneration Previously Treated With Faricimab
Authors: Momenaei Bita , Yonekawa Yoshihiro , Abril Paige , McCullough Rachel , Abbey Ashkan M.
Published: January 2025

Background and Objective

To assess the efficacy of intravitreal aflibercept 8 mg in treating neovascular age-related macular degeneration (nAMD) in patients previously treated with faricimab.

Patients and Methods

A retrospective study was conducted on nAMD patients with suboptimal response to faricimab injections who were switched to intravitreal aflibercept 8 mg. Visual acuity (VA) and optical coherence tomography features were evaluated.

Results

The study included 135 eyes from 85 patients who received an average of 7.4 (4) faricimab injections with a mean interval of 53 days, which decreased to 48 days by the 5th aflibercept 8 mg injection (
P
= 0.056). Mean VA at the time of switch was 63.9 (14.4) letters and was 65 (13.5) letters after four aflibercept 8 mg injections (
P
= 0.726). Mean central foveal thickness (CFT) at switch was 325 (104) µm which decreased to 272 (65) after four aflibercept 8 mg injections (
P
< 0.001). The incidence of intraretinal fluid and subretinal hemorrhage increased from 31.3% and 8.1% at switch to 52.2% and 21.7% (
P
= 0.029 and 0.004), respectively.

Conclusions

Switching from faricimab to aflibercept 8 mg did not result in interval extension or VA improvement. CFT decreased, but intraretinal fluid and subretinal hemorrhage increased. Further studies are warranted.

Optimal control of production and maintenance: A cost-efficient approach through inventory and preventive strategies
Authors: Bounkhel Messaoud , Tadj Lotfi
Published: January 2025

Using an optimal control framework, the optimization of production and maintenance processes is investigated in this paper. We focused on analyzing system behavior, managing costs, and controlling quality. Differential equations are utilized to model the relationship between inventory level, production, and maintenance strategies. A cost function is built combining different cost elements, and the optimal production and maintenance rates were obtained. A sensitivity analysis is performed to assess the impact of different parameters on the total cost and on the optimal solution. The key findings demonstrated that higher initial inventory levels significantly decreased long-term costs and improved production efficiency. The optimal preventive maintenance strategy emphasized the importance of early investments in quality and maintenance, leading to sustained operational stability.

Brumaire, un coup d’État sans éclat ?
Authors: Moullier Igor
Published: January 2025

L’article explore les événements des 18 et 19 brumaire et met en lumière leur préparation à travers le témoignage des acteurs impliqués. Le coup d’État de Brumaire apparaît comme prévisible et prévu par de nombreux acteurs. Si l’alliance de plusieurs groupes d’acteurs plaçant leurs espoirs en Bonaparte est évidemment essentiel, le succès du coup d’État résulte aussi de la maîtrise de détails matériels, de la procédure parlementaire à la mise en scène de la journée du 19 brumaire pour permettre l’ajustement du comportement des acteurs, et peut être analysé à travers la grille de lecture des crises politiques proposée par Michel Dobry et Ivan Ermakoff.
Dix objets qui ébranlèrent le monde. Russie, 1917-1921
Authors: Sumpf Alexandre
Published: January 2025

Tout au long de l’année 1917, en Russie, les objets ont été utilisés par les révolutionnaires à la fois comme outils d’affirmation de leur statut et comme signe de ralliement. Ces objets parfois fragiles, comme le premier décret de l’histoire en langue ukrainienne, un dessin d’enfant ou une ampoule électrique, ou létaux, comme les armes brandies par les ouvriers dans les usines, ont mobilisé les sens – la vue avec le drapeau rouge, l’ouïe avec les chants révolutionnaires – et suscité des émotions. Ils ont participé de l’expérience politique accélérée des nouveaux citoyens, entre marketing politique (la casquette de Lénine), incarnation concrète du pouvoir démocratique (le bulletin de vote), et tous types de propagande – par le film (pour le vote), l’affiche, les parois décorées des trains d’agitation des Rouges ou la politique monumentale. La floraison des images et des supports a fait de la rue un objet façonné en commun, et a permis aux citoyens de prendre conscience de la mutation radicale de l’espace public.
L’invention du concept d’adultisation par Guy Avanzini : Néologisme, Déplacement et Méprise
Authors: Andrieu Bernard , Mougniotte Alain
Published: January 2025

Guy Avanzini, avant de développer sa philosophie de l’éducabilité des adultes dans ses ouvrages des années 1990, avait fondé ce concept d’Adultisation sur une réflexion sur l’adolescence. Si nous n’avons trouvé la source de son invention dans les manuscrits de Guy Avanzini, la postérité du terme, qui aurait découvert le terme par les psychanalystes de l’adolescence en 1985 !, prouve que l’éducabilité est au centre de son anthropologie philosophique.

Multi-Objective Optimization of Traditional Feature Selection Methods
Authors: Mehta Hetavi Dilip , Mangrulkar Ramchandra
Published: January 2025

Feature selection is crucial in data analytics, as it helps identify the most relevant features for modeling. This improves efficiency and interpretability by reducing data dimensionality. Conventional methods optimize a single criterion, such as accuracy or information gain. However, these methods may not fully capture the complexity of real-world problems with multiple competing objectives. Recently, multi-objective optimization techniques have been applied to traditional algorithms, offering a framework for optimizing feature subsets that balance several objectives, such as precision and robustness. However, determining the most efficient algorithm for a specific dataset is challenging. This chapter aims to provide practitioners with a detailed examination of various multi-objective feature selection approaches, including their strengths, weaknesses, and a case study. By understanding the benefits of considering multiple objectives, professionals can apply these advanced methods to research projects, decision-making, and real-world data analytics problems.

Cross-Border Merger and Acquisitions (M&A) Challenges and Opportunities
Authors: Yang Tan , Xun Jiyao
Published: January 2025

The objective of this book chapter is to provide readers with some ideas and insights into cross-border M&A processes by sharing three real-life cases. Rather than offering a textbook version of the subject, the chapter will focus on the global blood plasma sector, a sub-segment of the pharmaceutical industry. By the end of the chapter, readers should have developed a basic understanding of the following: (1) Cross-border M&A processes; (2) Key considerations; (3) Key challenges and ways to deal with them; and (4) Basic terminologies through case context. The motivation for the acquisition is threefold: high entry barriers, strong market demand and profitability and the potential for synergies. However, the pursuit of this strategy is not without its challenges. At the macro level, the regulatory approval process poses significant hurdles. The Committee on Foreign Investment in the United States (CIFIUS), the United States National Security Review, and the Federal Trade Commission (FTC) all play a role in this process. Additionally, cultural challenges must be considered.
Action Research as Practice-Led Research for Professional Development
Authors: Lu Huijin
Published: January 2025

Action research has been regarded as an integral session of practice-led research. In the context of education, action research is perceived as an effective tool for institutions, schools, and classrooms to enhance teaching, and has been widely adopted by teaching faculties all over the world in an internationalized teaching context (i.e., Transnational Education) for Personal Development Planning (PDP). Thus, the present chapter aims to focus on a dedicated teaching and learning context of Transnational Education (TNE) to explore how to practically improve students' learning motivations through “learning by doing”. Data were recorded and collected from multiple sources, including students' module feedback questionnaires and teaching session observation. Based on data, it is found that the completion rates of after-class exercises, weekly time spent on the module as well as the learning experiences increased significantly. A new multi-dimensional teaching and learning model in TNE is introduced to include cognitivism, social constructivism, and technology-enabled learning.

A partir da exposição de materiais científicos em eventos abertos ao público, o projeto “Resiliência em sistemas socioambientais ribeirinhos na Amazônia” do Programa Amazônia+10, tem exitosamente feito a difusão de informações sobre a correlação entre a importância da conservação do bioma amazônico e os ecossistemas paranaenses. O projeto é desenvolvido em parceria entre docentes e discentes da Universidade Estadual de Maringá, da Universidade Federal do Amazonas, da Universidade Federal de Alagoas e do Instituto Nacional de Pesquisas da Amazônia e, em maio de 2024, participou da Exposição Feira Agropecuária, Industrial e Comercial de Maringá (Expoingá) com uma mostra de materiais sobre rios voadores e comunidades tradicionais ribeirinhas. Ao longo dos 10 dias de evento, cerca de 200 mil pessoas visitaram o pavilhão com a exposição do projeto. Durante as visitas, o público da feira pôde observar os materiais e tirar dúvidas com os discentes voluntários. Dentre as interações, uma pequena parcela do público apresentou conhecimentos prévios sobre os conceitos relacionados às comunidades, a maioria, nativa da macrorregião Norte. Além disso, a maioria do público interessado tinha idade acima dos 30 anos. Ações de divulgação científica como essa, quando realizadas durante grandes eventos, fornecem informações valiosas ao público visitante, que pode levar esse conhecimento para suas cidades, estimulando a criação de iniciativas semelhantes, ampliando o alcance de iniciativas de divulgação científica e  ações de conservação ambiental.

Resultados: Os resultados sugerem que empresas com características prospectoras apresentam menor prática de GR. No entanto, ao incluir incentivos ao GR na análise, constatou-se que empresas prospectoras mais alavancadas tendem a apresentar menores níveis de accruals discricionários.
Contribuição: Como contribuições do estudo, se destaca a interação entre um aspecto da contabilidade gerencial (tipo da estratégia do negócio), e a contabilidade financeira (prática de GR), algo ainda incipiente, principalmente no Brasil. O estudo contribui ainda ao fornecer informações úteis para stakeholders, investidores e analistas, pois sugere que o esforço para a maior qualidade da informação contábil pode estar relacionado à estratégia de negócio adotada pelas empresas.
Do majority shareholder control deviation results in financial constraints?
Authors: Bernardi Sonza Igor , Granzotto Alberto
Published: January 2025

Purpose: This study aims to analyze how the moral hazard of the majority shareholder results in financial constrainsts for Brazilian companies listed on Brazil, Bolsa and Balcão (B3).Method: we used the Ordinary Least Squares (OLS) to compare the cash flow sensitivity of cash for firms that have high control deviations control, presenting high moral hazard (constraints), with companies that have low control deviations, presenting low moral hazard (no restrictions).Originality/Relevance: The originality of the research resides in the evidence that the deviation of shareholding control can be understood as a source of credit restriction, putting in check a particular and idiosyncratic source in emerging markets such as Brazil.Results: our first result evidenced that, in historical terms, the control deviation declined significantly. On the other hand, the results reveal that the moral hazard of the majority shareholder, represented by the deviation of control, results in financial restrictions of Brazilian companies listed on B3.Theoretical/methodological/practical contributions: the main implication of the research is to reveal idiosyncratic sources of credit in Brazil, since the majority shareholder control deviation (MSCD) reflects the weak legal protection for minority shareholders and creditors (civil law). This research helps capital market investors in countries with weak legal protections to choose companies that are concerned about governance issues, as well as companies to understand that such deviations can be harmful to corporate debt.
Uniformização de práticas de gestão estratégica portuárias: modelo construtivista para uma Holding Catarinense
Authors: Pedersini Daiana Rafaela , Ensslin Sandra Rolim
Published: January 2025

Objetivo: O estudo objetiva construir um modelo construtivista de avaliação de desempenho para apoiar a Holding no processo de uniformização das práticas de gestão estratégica das atividades portuárias.
Método: Por meio de entrevistas semiestruturadas com o gestor da Holding e com a participação de um especialista, utilizou-se a metodologia Multicritério de Apoio à Decisão-Construtivista. Tal processo fez uso da recursividade das etapas, pois, devido à geração de conhecimento propiciado em determinado estágio de evolução do processo, o gestor portuário constatou que as informações constantes no protótipo do modelo não atendiam fielmente às necessidades da organização. Com isso, todo o processo foi revisto e o modelo final ficou constituído de 26 indicadores.
Resultados: Foi delineado o desempenho dos Portos delegados e sinalizado os indicadores em que os Portos possuíam um desempenho aquém do desejado. Com o suporte de informações geradas e imbuído do propósito de uniformização das práticas de gestão estratégica, o gestor da Holding propôs ações a cada um dos Portos que possibilitassem aprimorar o respectivo desempenho. Para os indicadores em que os Portos apresentaram desempenho em nível de excelência, o gestor identificou quais eram as boas práticas de gestão e sugeriu sua disseminação entre as demais subsidiárias, operacionalizando, assim, a uniformização de práticas de gestão propostas, contribuindo para o processo de gestão efetiva da atividade portuária.Originalidade: O trabalho advém da proposta de desenvolvimento de um modelo de avaliação de desempenho para apoiar uma holding portuária na gestão do processo de uniformização de práticas de gestão estratégica das atividades entre seus portos delegados, tendo em vista a inexistência de estudos pregressos sobre o tema.
Contribuições: Contribui tanto para a gestão pública, quanto para o conhecimento teórico, pois oferece evidências empíricas sobre o processo de gestão pública de portos feito por holdings.

Authors: Teodósio Igor Rodrigo Menezes , Sobreira Karoline Rodrigues , Medeiros Jislene Trindade , De Luca Marcia Martins Mendes
Published: January 2025

Objetivo: Este estudo tem o objetivo de investigar a relação entre os mecanismos externos de controle da gestão e o nível de atividades de tax avoidance nas empresas brasileiras.
Método: A amostra foi composta por 70 empresas listadas na B3, no período de 2015-2019. O nível de tax avoidance foi mensurado pelos modelos propostos por Tang (2014) e Atwood et al. (2012). Os mecanismos externos de controle da gestão foram mensurados pela qualidade da governança, tamanho e independência do comitê de auditoria, qualidade da auditoria e o monitoramento de analistas financeiros. Fez-se uso de estatística descritiva e multivariada.
Originalidade/Relevância: Dada a complexidade do sistema tributário e as fragilidades institucionais do Brasil, gestores podem identificar este ambiente como propício para adotar práticas de tax avoidance. Portanto, mostra-se relevante analisar como os mecanismos externos de controle podem afetar o nível de agressividade fiscal das empresas, de modo a inibir o oportunismo dos gestores decorrentes de práticas de redução de tributos.
Resultados: Os resultados demonstraram níveis elevados de tax avoidance praticado pelas empresas brasileiras. Ademais, sinalizam que a presença do comitê de auditoria promove a adoção de estratégias de tax avoidance, e que quanto maior e mais independente for o comitê de auditoria, menor será a probabilidade dessas estratégias serem agressivas. Observou-se, ainda, que quanto mais as empresas se engajam em atividades de tax avoidance, maiores são os erros de previsão do lucro.
Contribuições Teóricas/Metodológicas/Práticas: O estudo contribui para enriquecer a literatura sobre tributos, pois sinaliza como alguns mecanismos externos de controle podem restringir práticas de tax avoidance, refletindo-se, assim, nos custos de agência decorrentes do monitoramento das ações de gestores quanto às questões tributárias. Os resultados podem ainda auxiliar órgãos governamentais na elaboração de políticas públicas para evitar perdas de receitas fiscais.
Early and late outcomes of emergency coronary bypass grafting in non-ST-segment elevation acute myocardial infarction

Published: January 2025

The majority of patients undergoing emergency coronary artery bypass grafting for non-ST-segment elevation myocardial infarction are of advanced age and have many comorbidities, which pose challenges for operation. This study aimed to determine the early and midterm outcomes of this subgroup. The study conducted a retrospective analysis on 89 patients who experienced non-ST-elevation acute myocardial infarction and underwent emergency coronary artery bypass graft surgery at Hanoi Heart Hospital in Hanoi, Vietnam, between January 1, 2020, and December 31, 2022. The primary outcome variable was in-hospital mortality, and the secondary outcome variable was midterm mortality. The mean age of the cohort was 66.4 years. Female accounted for 31.46%. Over half of patients (53.9%) were operated on within 24 hours from the onset of symptoms. The average European System for Cardiac Operative Risk Evaluation (EuroSCORE II) was 10.55%. The number of coronary bypasses was 3.4. Aortic cross-clamp and cardiopulmonary bypass times were 64.2 and 94.4 minutes. The in-hospital mortality rate was 10.11%. Significant predictors determining in-hospital mortality were the EuroSCORE II score. The mean follow-up time was 28.2±12.2 months. Survival rates at 1 year and 2 years were 97.5% and 96.02%, respectively. Emergency coronary bypass surgery in patients with non-ST segment elevation myocardial infarction had poor early but good midterm outcomes. A high EuroSCORE II score was a predictor of in-hospital mortality.
An observational study to evaluate the utility of surgical plethysmographic index as a tool to predict postoperative pain in patients receiving oral calcium channel blocker therapy
Authors: Shenoy Sweekar K. , Handattu Krishna M. , Muhamed Shiyad
Published: January 2025

Background and Aims:

Surgical plethysmographic index (SPI) is a monitoring parameter used to predict postoperative pain. Our primary objective was to determine whether the value of SPI obtained 10 min before expected completion of surgery can be used as a reliable tool to predict postoperative pain in patients receiving oral calcium channel blocker (CCB) therapy for hypertension. Our secondary objective was to determine if SPI can be used as a tool to predict awakening of the patient from anesthesia.

Materials and Methods:

Seventy patients on CCB were enrolled. SPI values at 10 min before the anticipated end of the surgical procedure were recorded. The mean value of 10 readings was calculated and used as the SPI score for the patient. The time that anesthetic was cut off till the time of extubation was taken as the time of awakening. Numerical rating pain scale assessed the patient’s level of postoperative pain 15 min after extubation. Thirty-five patients not on CCB were studied similarly to serve as controls. Data obtained were analyzed using Statistical Package for the Social Sciences version 28 for Windows through the Department of Medical Statistics. P value less than 0.05 was considered significant.

Results:

In patients on CCB, based on the r value, a positive correlation was noted between the mean SPI and NRS values on scatterplot (P = 0.009). In patients not on CCB, a positive correlation was noted between mean SPI and NRS. In both groups, a negative correlation was noted between mean SPI and awakening time, which was not significant.

Conclusions:

In patients receiving oral CCB, SPI values obtained 10 min before expected completion of surgery can be a reliable tool to predict postoperative pain, but not to predict awakening from anesthesia.
Estimation of blood lactate and bicarbonate levels after stored blood transfusion to predict ICU admission in patients undergoing major head and neck surgeries: A prospective observational study
Authors: Dorathy N Sonia , Payal Yashwant S. , Talawar Praveen
Published: January 2025

Background and Aims:

Major head neck surgeries are often associated with major blood loss requiring blood transfusion. However, in spite of transfusion, patients usually suffer adverse postoperative outcomes. Biomarkers can help in identifying such events early. This observational study was conducted to compare blood lactate and bicarbonate levels as predictors of adverse postoperative outcomes.

Materials and Methods:

Forty-eight adult American Society of Anesthesiologists Physical Status I–III patients met the inclusion criteria. Intraoperative blood loss was managed with stored blood transfusion as per transfusion trigger. Blood lactate and bicarbonate levels were measured preoperatively (Tbas), at the immediate postoperative period (T0), and at 8 h (T8), 16 h (T16), and 24 h (T24) postoperatively. Outcomes such as need for intensive care unit (ICU) admission, length of ICU stay, intraoperative blood transfusion, re-exploration rate, and mortality were recorded.

Results:

Blood transfusions and ICU admissions were required in 19 (39.6%) and 24 (50%) patients, respectively. Lactate levels of patients requiring blood transfusion and admission to ICU rose significantly from their baseline (1.30 ± 0.41 mmol/l) to 2.80 ± 1.14 mmol/l at the immediate postoperative period, which fell to 2.06 ± 0.78 mmol/l at 24 h postoperatively, compared to other patients who did not require transfusion and ICU admission (P < 0.001). The bicarbonate value did not show any significant change from its baseline (22.68 ± 1.83 mEq/l) at all time points (P = 0.8). In addition, no significant difference was noted regarding ICU admissions (P = 0.659) or blood transfusions (P = 0.788).

Conclusions:

Following major head and neck surgeries, blood lactate level is a good predictor, but bicarbonate is a poor predictor of the need for blood transfusions and ICU admission. Intraoperative blood transfusion failed to prevent rise in blood lactate level, which is taken as a surrogate marker of tissue hypoxia.
