Deux chercheurs gallois sur le terrain français : une collaboration au long terme
Authors: Meirion-Jones Gwyn
Published: July 2023

L’histoire médiévale française, et particulièrement celle de la Bretagne ducale, a dominé la vie de chercheur de Michael Jones dès ses années d’étudiant à Oxford. Ses publications, livres et articles, témoignent d’une carrière exceptionnelle. Bien que la plupart de ses travaux concernent la France, il a également trouvé le temps de se consacrer à d’importants projets en Angleterre, en tant qu’auteur, éditeur, parfois les deux. Retraité, il s’est intéressé à l’histoire locale de Norwell, sa paroisse. Il a par ailleurs édité de nombreux textes médiévaux.Depuis le début des années 1980, il a participé activement à notre équipe de recherche sur les manoirs et petits châteaux de Bretagne. Mais il a également contribué de manière significative à nos autres activités en France, y compris à l’important travail sur les maisons de ville de Cluny ainsi qu’à l’étude pluridisciplinaire du site du Yaudet.Chaque année il a contribué à un séminaire privé franco-britannique destiné à explorer les bâtiments domestiques seigneuriaux mineurs d’autres régions françaises. Ces séminaires ont donné lieu à la publication de trois volumes collectifs.Enfin, il a participé avec enthousiasme aux congrès annuels de la Société d’Histoire et d’Archéologie de Bretagne (SHAB) dont il est actuellement le plus ancien membre siégeant dans le comité. Il y a publié de nombreux articles, dont les monographies de bâtiments seigneuriaux que nous présentions lors des congrès annuels. La SHAB a édité ou subventionné plusieurs de ses ouvrages consacrés à Jean IV. Cet article montre ainsi toute l’étendue de l’apport de Michael Jones à l’histoire médiévale.
Le paysage castral breton au temps du duc Jean Ier le Roux (1237-1286)
Authors: Kernévez Patrick
Published: July 2023

Au cours du xiiie siècle, les ducs de Bretagne étendent leur domaine, mettant la main sur les châteaux de certains barons, notamment au nord du duché. Jean le Roux se retrouve ainsi à la tête d’un réseau de plusieurs dizaines de « châteaux », parfois de simples résidences et lieu de perception, quelquefois militairement déclassés, mais aussi des édifices « modernes », comme à Nantes, le Gavre ou Saint-Aubin-du-Cormier. Ces ouvrages d’inspiration royale sont ostentatoires avec leurs tours circulaires percées d’archères et leur tour maîtresse cylindrique. La fonction résidentielle peut parfois prévaloir, comme au « manoir » de Suscinio reconstruit par Jean le Roux vers le milieu du xiiie siècle. Les barons ne sont pas en reste : ceux de Vitré et de Fougères reconstruisent leur forteresse éponyme dans les années 1220-1240 et modernisent des châteaux secondaires, d’anciennes mottes, à Marcillé-Robert et à Marcillé-Raoul. D’autres seigneurs érigent alors un château où ils adoptent aussi les principes de cette architecture novatrice que l’on retrouve dans quelques enceintes urbaines, comme à Vitré, Fougères ou Dinan. On recense néanmoins toujours des centaines de mottes, édifices avant tout ostentatoires voire éphémères, et déjà peut-être autant de « manoirs », résidences élitaires peu ou pas fortifiées, majoritairement érigées par des lignages de la moyenne et de la petite noblesse. Le paysage castral breton du règne de Jean le Roux apparaît ainsi pluriel et mouvant.
L’enceinte urbaine de Vitré, André III, le duc et le roi (deuxième quart du xiiie siècle)
Authors: Pichot Daniel
Published: July 2023

André III, maître de la puissante seigneurie de Vitré entreprit la reconstruction de son château et la construction de la première enceinte urbaine en pierre dont subsiste une large partie. La documentation date avec précision les travaux dans le second quart du xiiie siècle et laisse envisager les conséquences urbanistiques pour l’agglomération. Au-delà, le contexte politique et diplomatique permet de comprendre cette entreprise très précoce en Bretagne. Le seigneur de Vitré, puissant vassal du duc de Bretagne, maître d’une seigneurie à la frontière avec le royaume, joue un jeu complexe avec le duc et s’appuie sur le roi qui voit la possibilité de s’immiscer dans les affaires du duché et finance largement les travaux du baron.
François Plaine et Charles de Blois : de l’histoire à la béatification
Authors: Guigon Philippe
Published: July 2023

Notre ami Michael Jones a reconnu devoir « une dette énorme » aux travaux de François Plaine (1833-1900) sur Charles de Blois. Ce moine explora des monceaux d’archives afin, tout d’abord, d’obtenir sa béatification (1904), et publia de nombreux articles historiques, s’attirant les foudres d’Arthur de La Borderie, mais il ne réussit pas à faire éditer de son vivant son Histoire de Charles de Blois. Il existe bien d’autres exemples similaires de sanctifications tardives, avortées à la fin du Moyen Âge, Françoise d’Amboise (1863), Jeanne de Maillé (1871) et la plus illustre Jeanne d’Arc (1920). Une si longue procédure envers Charles peut s’expliquer en raison des querelles entre ultramontains, tels les bénédictins, et gallicans, ainsi Augustin David, évêque de Saint-Brieuc et Tréguier. Avoir comme défenseur un catholique intransigeant avait également nuit à la réputation du duc, attaquée par le républicain Henri Martin. En dépit de la confusion des genres entre histoire et apologétique, l’œuvre archivistique que lui consacra Plaine demeure encore solide de nos jours.
Artillerie, fortification et politique d’indépendance en Bretagne à la fin du Moyen Âge
Authors: Kerhervé Jean
Published: July 2023

Pas d’indépendance possible sans entretien ni modernisation de l’appareil défensif de l’État. C’est l’un des aspects de la politique des derniers ducs de Bretagne de la dynastie des Montforts (1364-1491), si l’on en juge par les préambules et les exposés de leurs ordonnances militaires, dont témoignent aussi les documents financiers et les témoins archéologiques mis en œuvre dans cet article. Leur effort de guerre se traduit à la fois par la mise en place d’une administration spécialisée, dirigée par un maître de l’artillerie assisté d’un clerc, chargé de la comptabilité, l’utilisation d’un personnel technique qualifié (canonniers et artilleurs), recruté à l’échelon européen aussi bien qu’en Bretagne, la création d’un parc d’artillerie bien au fait des derniers perfectionnements et l’adaptation à l’arme nouvelle des fortifications urbaines et des châteaux, principalement sur les frontières orientales du pays (« marches ») et les côtes, financées par l’argent de l’État et des grandes villes. Cet effort de défense est à mettre en parallèle avec les prétentions politiques d’une principauté que rien ne rattache plus au royaume après la création du parlement souverain de Bretagne (1485) et l’avènement de la duchesse Anne (1488), dont le roi n’a pas requis l’hommage. La vanité de cette politique de défense, largement inspirée du modèle français, n’est donc pas vraiment d’ordre qualitatif, mais tient pour l’essentiel à la différence de proportions entre les capacités d’un royaume dix fois plus peuplé, dont les moyens financiers sont dix fois supérieurs, et celles d’un duché incapable de supporter le coût d’une guerre relancée chaque année par la France pendant cinq années (1487-1491). La Bretagne vaincue et « mariée » à la France, c’est donc le roi qui récolte les fruits de l’énorme investissement des ducs en matière militaire et hérite à la fois d’un arsenal et d’un réseau de forteresses modernisés qu’il se garde bien de démanteler.
Deux princes au xive siècle, Charles de Navarre et Jean de Montfort
Authors: Charon Philippe
Published: July 2023

Jean de Montfort et Charles de Navarre étaient tous les deux des vassaux du roi de France dont ils ont secoué la suzeraineté. Ils dotèrent chacun leur principauté des institutions modernes de l’État imitées du modèle royal et à même de concurrencer ce dernier, mais ils ne parvinrent pas à s’affranchir de l’hommage dû au roi de France. Leur principauté était exposée aux exactions des compagnies, ce qui déclencha un premier rapprochement en 1369-1370, sans suite. Si l’un et l’autre cherchèrent à tirer parti de l’opposition franco-anglaise, ce fut chacun de leur côté en fonction d’intérêts et de temporalités qui ne convergèrent pas. Ce fut finalement la recherche par Jean d’une troisième épouse qui les rapprochèrent : en 1386 était célébré le mariage du duc avec une fille de Charles, l’infante Jeanne. S’il permit d’assurer la descendance dynastique des Montfort, Navarre ne put en tirer les avantages escomptés car il mourut quatre mois plus tard. Il espérait que cette alliance lui permettrait de reprendre pied dans sa principauté conquise militairement par Charles VI en 1378, l’année même où était prononcée la confiscation du duché. Mais à la différence de la principauté normande, la noblesse bretonne fit bloc autour de son duc, alors que la noblesse normande ne marqua aucune solidarité envers son suzerain. À travers les destinées croisées de ces deux féodaux, ce sont les ambitions politiques de princes territoriaux qui se révèlent et leur habilité à les mettre en œuvre.
Guérande-Le Croisic, ports d’armement maritime vers l’Espagne (1384-1386)
Authors: Gallicé Alain
Published: July 2023

Trois documents remarquables concernent l’activité maritime à partir de l’ensemble portuaire de Guérande : un compte du mouvement des navires en partance de celui-ci (du 31 octobre 1384 au 26 janvier 1386), une lettre de rémission accordée par le roi de France Charles V (décembre 1385), et le compte, tenu par Pierre de Lésiner, relatif au voyage pour « aller querir » Jeanne de Navarre, devenue l’épouse de Jean IV (2 juillet et septembre 1386). Leur croisement fait apparaître que le navire nommé Saint-Esprit, cité dans la lettre de rémission, se retrouve dans le compte portuaire (de façon anonyme et sans indication de destination), et qu’il doit être identifié à la « barche du Connétable » Pierre de Lesnerac. Leur croisement permet encore d’établir que les relations entre le pays guérandais et l’Espagne se font plus actives à la fin 1385 et au début 1386 et que le commerce guérandais est doté d’une organisation commerciale moins rudimentaire que ne le donne à penser la simple lecture du compte portuaire.
« Perfidie des Anglais et incurie des Français »
Authors: Bachelier Julien
Published: July 2023

Dans la nuit du 24 au 25 mars 1449, les troupes du mercenaire François de Surienne, à la solde des Anglais, attaquent la place forte de Fougères, ville ducale et une des « entrées et yssues du duché de Bretagne ». L’un des objectifs aurait été d’obtenir la libération de Gilles de Bretagne, frère du duc et partisan pro-anglais. La monarchie lancastrienne cherche surtout à déstabiliser la Bretagne, alors que la Bourgogne s’est rapprochée de la Maison de Valois. La trêve dite de Tours, négociée en 1444 entre le royaume de France et celui d’Angleterre, vole en éclats avant son expiration officielle le 1er avril 1450. La guerre de Cent ans reprend, le duché breton s’allie au royaume de France. Mieux organisé et mieux préparé, le camp français l’emporte et, en 1453, seule Calais demeure anglaise. Les conséquences nationales et régionales du sac de Fougères sont connues. Le détail de l’attaque reste cependant à explorer et les conséquences de l’assaut sur la ville et ses habitants ont rarement été abordées. Fougères est ruinée, pour plusieurs décennies. On renforce le château et les remparts, qui ne résistèrent qu’une petite semaine en juillet 1488, quelques jours avant la défaite bretonne de Saint-Aubin-du-Cormier.
La carrière de chancelier de Bretagne de Rainaud, évêque de Quimper († 1245) : nouvelle approche, nouvelles hypothèses, nouvelles perspectives
Authors: Bourgès André-Yves
Published: July 2023

Plusieurs indices viennent au soutien de l’hypothèse que la carrière de chancelier de Bretagne de Rainaud, évêque de Quimper (†1245) pourrait avoir débuté bien avant l’accession au pouvoir de Pierre de Dreux (1213), contrairement à l’opinion qui prévaut aujourd’hui chez les spécialistes. Si cette hypothèse était confirmée, le rôle joué par Rainaud, outre l’allongement de la durée de ses fonctions, devrait faire l’objet d’une réévaluation en termes de stabilité des institutions du duché et de continuité de la politique ducale ; ce serait également l’occasion de montrer que la littérature hagiographique, en ce qu’elle apparaît souvent comme le reflet de préoccupations idéologiques, peut contribuer à nourrir ce type de conjecture.
Les comptes de l’hôtel de Marie, duchesse d’Anjou (1365-1366)
Authors: Graham-Goering Erika
Published: July 2023

Cette édition critique du compte de l’hôtel de Marie de Bretagne (Archives nationales, KK 241) rend hommage non seulement à l’expertise de Michael Jones en tant qu’éditeur prolifique de documents d’archives relatifs à la famille ducale bretonne, mais aussi à ses recherches fondamentales sur le duché à la fin du Moyen Âge, sur les modes de vie aristocratique et sur les pratiques documentaires administratives. Le compte de Marie, qui s’étend du 13 juillet 1365 au 7 mars 1366, tombe à point nommé pour donner un aperçu des conséquences de la défaite de ses parents, Charles de Blois et Jeanne de Penthièvre, duc et duchesse de Bretagne, dans la Guerre de succession. Par exemple, Marie a accueilli son frère cadet pendant que leur mère s’occupait d’affaires ailleurs, et a commandé une messe pour l’âme de son père. Plus généralement, ce compte donne des informations détaillées sur les aspects matériels, organisationnels et logistiques du ménage d’une princesse. Il est divisé en quatre sections : argent reçu, dépenses quotidiennes, dépenses extraordinaires et provisions en nature. Ces éléments nous permettent de reconstituer l’itinéraire habituel de Marie en Anjou et sur un long voyage en Languedoc (dont son mari était le lieutenant royal), les relations au sein et en dehors de son entourage, et la consommation de luxe en ce qui concerne la nourriture, les vêtements, le mécénat. Un dernier aspect de l’intérêt de ce compte réside dans sa composition particulière : les registres originaux ayant été détruits lors du siège de Vaas en 1370, le comptable ducal a établi ce remplacement en 1376 en notant soigneusement d’où il tirait ses informations. Nous pouvons donc voir comment un administrateur a utilisé des documents provenant de différentes parties de l’hôtel pour reconstituer l’un des innombrables documents perdus dans la violence de la guerre de Cent Ans.
Des revenus pour la châtellenie de Guémené entre 1390 et 1395 : un fragment de compte inédit
Authors: Sallansonnet Maud
Published: July 2023

Les Archives départementales du Morbihan conservent dans le fonds de la juridiction seigneuriale de la principauté de Guémené, sous la cote B 5147, un fragment de compte inédit et probablement inconnu restituant les recettes dues entre Noël 1390 et Noël 1395 à Charles de Rohan. Celui-ci se trouve être le premier seigneur de Guémené après que ses parents Jean Ier de Rohan et Jeanne de Navarre ont acquis en 1377 la seigneurie à son profit. Ce long parchemin de 3,5 m pour 29 cm de large, composé de sept peaux cousues, semble cependant incomplet : aucune couture ni déchirure n’est visible en tête du rouleau pourtant les informations qu’il comporte ne paraissent correspondre, calculs à l’appui, qu’à la moitié des recettes ; en outre les informations habituellement détaillées en préambule de ce type de document sont totalement absentes. Malgré cela, cette pièce d’archives demeure remarquable, du fait de sa date d’abord, antérieure à 1400, puis des données qu’il expose : différents types de recettes, dont surtout liées au guet, indications géographiques, noms de débirentiers et d’officiers, données démographiques sur les paroisses de la seigneurie ; on peut également y voir l’application pratique de l’usement de Rohan dans certains domaines.
La diversité du conseil d’administration importe-t-elle réellement aux actionnaires ?
Authors: Blomkvist Magnus , Redor Etienne
Published: July 2023

La diversité du conseil d’administration importe-t-elle réellement aux actionnaires ? Pour répondre à cette question, nous avons écarté l’approche traditionnelle reposant sur l’analyse du lien entre diversité du conseil d’administration et valeur d’entreprise afin de nous concentrer sur les résultats des élections annuelles des administrateurs par les actionnaires. A l’aide d’un échantillon de données collecté manuellement, nous concluons que la diversité importe aux actionnaires. Nous montrons que le soutien des actionnaires envers les administrateurs issus de la diversité s’explique principalement par les votes pour les administrateurs issus des minorités, ce qui constitue une nouveauté dans la littérature. Notamment, nous montrons que le vote en faveur des administratrices non caucasiennes peut pleinement expliquer le soutien des actionnaires pour les administratrices. Notre étude a des implications sur la sélection des administrateurs et montre que la diversité du conseil d’administration est précieuse pour les actionnaires.
Integration of CSR into CEOs’ compensation: effects on social and financial performance of French listed firms

Based on the stakeholder model of corporate governance, this research analyzes the relationship between the integration of corporate social responsibility (CSR) into CEO compensation and corporate social and financial performance, in firms listed on France’s SBF 120 stock market between 2015 and 2019. The results of panel data regressions show that indexing CEO compensation on CSR criteria only influence corporate social performance Moreover, social performance has a positive impact on financial performance and a mediating effect between the integration of CSR criteria into CEO compensation and financial performance.
Frontline Employees’ Job Satisfaction in Microfinance Institutions: Scale Development and Validation
Authors: Kanyurhi Eddy Balemba , Akonkwa Deogratias Bugandwa Mungu , Cubaka Patrick Murhula , Mbonekube Willem Bitakuya
Published: July 2023

Studies that measure frontline employee job satisfaction in microfinance institutions (MFIs) are still scarce. The present study fills this gap and develops a measurement scale for MFIs’ frontline employees. Data were collected from 226 and 419 frontline employees from 50 and 53 MFIs in the Democratic Republic of the Congo. These data were processed through exploratory and confirmatory factor analysis and structural equation modelling. The results confirm that employee job satisfaction is a multidimensional construct with 10 factors. The scale was found to be reliable and valid, suggesting that the measure of job satisfaction has to be context and sector specific.
Open Water Jumping: Clearing Obstacles in the Negotiation of French Rights to The Black Stallion
Authors: Cottenet Cécile
Published: July 2023

Walter Farley’s stallion, Black, is certainly remembered as one of the most famous and beloved animals in Hachette’s Bibliothèque verte. The numerous titles in the “Black Stallion” series were reedited several times, and ultimately achieved high sales. The story of the introduction of the series in France in the aftermath of World War II, and its inclusion in this now-classic library of children’s texts, is largely unknown. Behind the scenes of the transatlantic negotiations, a narrative of complex, arduous discussions between author, series editor and agents unfolds, revealing the roles played by mediators usually forgotten by literary history. Based on archival evidence, this article develops a book history perspective to shed some light on these long negotiations that took place between 1941 and 1964.
Hermeneutic Keys and Pedagogic Tips
Authors: Nair D. Radhakrishnan , Joy Justin
Published: July 2023

Pedagogy sharpens and complements hermeneutics to form the prolegomena statement for this chapter. The chapter undertakes two approaches: It deals with closer understanding of the text in depth and also explains the findings of the text for pedagogical applications. The science of interpretations will provide a proliferation of meanings and interpretations. The lessons from pedagogy will facilitate a lot of assistance for academic and teaching purposes. Radhakrishnan Nair's hermeneutic keys and Justin Joy's pedagogic tips form the crux of the matter in the research paper. Here, research in case studies culminate in some useful findings related to comprehension and conception of case as text. However, quite legitimately the research demands a specialist partner in complementary pedagogical research, which compels to find a research association from the management faculty, at once competent in pedagogy. Justin Joy shares and resolves the problems Nair has confronted with.
Response of the Economic System to COVID-19
Authors: Ognjenović Kosovka , Đukić Mihajlo
Published: July 2023

This chapter specifically deals with the response of the Serbian economy and society to the challenges of the crisis, focusing on research conducted from 2020 to 2022. Bearing in mind that economic systems remember and learn from both good and bad experiences, it was interesting to see if, in this relatively short time, in terms of data availability, the analyses that were done offered results not only from a short-term but also from a long-term perspective. After the analysis of the available studies and the systematization of the main findings, it was concluded that the majority of these studies provide only analyses of the short-term effects without applying rigorous evaluation methods. This is an important limit in terms of their reliability, but also with regards to usefulness of the obtained results for the policy making purposes.
“We've Got Trouble in Cybercity”
Authors: Dereshiwsky Mary , Babb Danielle , Minarcine Suzanne M.
Published: July 2023

Online adjunct faculty encounter a unique set of stressors compared to traditional face-to-face faculty. This chapter provides a history of concerns raised by online faculty and one of the author's experiences in mentoring them. It also centers on a two-part study intended to identify the most prominent stressors perceived by online adjunct faculty. Part 1 consisted of individual in-depth interviews with online adjunct faculty members. The results were then applied to create a 30-item rating survey of the importance of identified stressors. The items clustered into five factors perceived as most stressful: student readiness, student communications, administrator communications, teaching load, and teaching expectations. The chapter then identified implications for administrators, including recommendations for practical application to create maximally effective and minimally stressful teaching environments for online faculty.
Internationalization in Higher Education
Authors: Geffner Rebecca B. , Craven Annette E.
Published: July 2023

This chapter explores how three schools within a born global African university with a strategic orientation toward internationalization differentiate their development of globally competent graduates. The embedded case study found that the schools did not identify specific internationalization strategies or metrics for the future nor substantially differentiate their perceptions of what defines a globally competent graduate. This appeared to be because the university was born global and did not feel the need to continue to internationalize. The chapter concludes by recommending further research to fill the gap in the literature on born globals and internationalization in higher education.
Artificial Intelligence in Video Surveillance
Authors: P. Uma Maheswari , V. R. Karishma , Vigneswaran T.
Published: July 2023

Surveillance is an essential component of security, and e-surveillance is one of the primary goals of the Indian Government's Digital India development initiative. Video surveillance offers a wide range of applications to reduce ecological and economic losses and becomes one of the most effective means of ensuring security. This chapter addresses the problem of how artificial intelligence is powering video surveillance. There is a significant research focus on video analytics but comparatively less effort has been taken for surveillance videos. However, there is little evidence that researchers have approached the issue of intelligent video surveillance in terms of suspicious action detection, crime scene description, face detection, crowd counting, and the like. Most AI-powered surveillance is based on deep neural networks and deep learning techniques using analysis of video frames as images. Consequently, this chapter aims to provide an overview and significance of how artificial intelligence techniques are employed in video surveillance and image processing.
Pattern Recognition by IoT Systems of Machine Learning
Authors: Sihare Shyam
Published: July 2023

Today, it is feasible to observe how quickly electronic devices are becoming connected to the internet. Electronic devices that are connected to the internet can be managed or observed from any location in the world. Many of the challenges have been made easier by internet connectivity for technological gadgets. A good judgement may be made by spotting certain trends using IoT and machine learning (ML) technologies. Its application areas can be expanded much farther than they are now by combining IoT and ML algorithms. ML uses a variety of algorithms, and while analysing them to choose the best one for a certain electronic device, runtime complexity, memory needs, and accuracy are taken into consideration. In comparison to other ML algorithms, support vector machine, random forest, and k-nearest neighbour have higher runtime complexity, a smaller memory requirement, and higher accuracy. In this chapter, the aforementioned topics have all been covered. The different ML algorithms and IoT pattern recognition application areas are covered in this chapter.
New Cloud Computing-Based Strategy for Coordinating Multi-Robot Systems
Authors: Urrea Claudio
Published: July 2023

Construction and manufacturing are performed in environments where automation is highly appreciated as it improves security and efficiency. This article proposes a new cloud computing-based strategy for coordinating multi-robot systems aimed to transport and manipulate heavy objects like a beam. The proposed solution is applied to a team of dynamically modeled selectively compliance assembly robot arms (SCARAs) with four degrees-of-freedom (4-DoF), simulated in virtual reality modeling language (VRML) and coordinated by a cloud server. The SCARAs are organized on a leader/follower configuration, so that the leader performs a computed trajectory, constantly reporting its position to the remote server and this, in turn, resends this information to the followers. The SCARAs are modeled using MatLab and they communicate through a transmission control protocol (TCP) with a Python process running in the cloud server to demonstrate the feasibility of incorporating cloud resources in a multi-robot system, testing their performance through simulation.

Published: July 2023

This study emphasises the need for energy efficiency in buildings, focusing primarily on the heating, ventilation, and air conditioning (HVAC) systems, which consume 50% of building energy. A predictive system based on artificial neural networks (ANNs) was created to generate short-term forecasts of indoor temperature using data from a monitoring system in order to reduce this energy use. The technology seeks to estimate inside temperature in order to determine when to start the heating, ventilation, and air conditioning system, potentially reducing energy use dramatically. The chapter describes the system's code implementation, which includes data pre-processing, model training and evaluation, and result visualisation. In terms of evaluation metrics, the model performed well and revealed the potential for large energy savings in buildings.

Conclusão: há necessidade de melhora do processo de cuidado durante o pré-natal. Dados essenciais para o cuidado pré-natal não foram preenchidos de maneira adequada.
Teaching and Learning of Attitudes, Ethics and Communication using the AETCOM Module in India
Authors: Fathima F. N. , Shankar N. , Lakshmi T. A.
Published: July 2023

The National Medical Council of India has introduced AETCOM in its new CBME curriculum to focus on learning in the affective domain. Learning in the affective domain was hitherto relegated to the hidden curriculum, poses unique challenges, and requires use of additional teaching-learning [TL] methods that are not routinely used. Most medical college faculty members are unfamiliar with these methods. Case vignettes, video clips, book review, mock ethics meetings, field visits, story-telling (patients /caregivers / doctors), standardized patients, feedback from alumni/seniors, guest lectures, ward rounds with ethical checklists, news-paper clippings, assignments and projects, student seminars/debates and role plays are some methods that can be used to improve learning in the affective domain. Any of the teaching learning methods for affective domain listed above should be followed by reflection using Boyd’s triangular reflection model (What happened? So what? and Now what?). Teaching attitudes, communication and ethics cannot be done in isolation. It must be integrated into routine patient care and other everyday experiences that medical students are exposed to.
Insight in a behaviour of Central European Red Kites wintering in Italy
Authors: Dostál Marek , Škrábal Jan , Raab Rainer , Caldarella Matteo , Literák Ivan
Published: July 2023

Migration and over-wintering strategy of raptors can be influenced by many factors such as sex, age and experience of birds, habitat variability and food availability. Based on the telemetry data of nine Red Kites (Milvus milvus), we observed in situ their wintering grounds in southern Italy during winter 2019/2020. Red Kites originated from Austria and the Czech Republic arrived to their wintering grounds from 10th September to 5th December 2019 and departed between 9th February and 7th May 2020. Tagged Kites stayed in their wintering grounds from 73 to 207 days (mean 135±46 SD). These birds occupied home range and the core area from 39 to 9,351 km2 (KDE 95%; mean 3,591±3,460 SD) and 6 to 1,998 km2 (KDE 50%; mean 566±483 SD), respectively. We observed a total of 242 Red Kites at nine communal roost sites (min. = 14, max. = 45 individuals) used by tagged Red Kites. Roosts were situated at an average altitude of 630 m above sea level. Agricultural countryside with small or large fields, small or large forest patches, meadows, pastures, sheep or cattle farms surrounded areas around communal roosts of Red Kites.
Regional-scale lake-sediment sampling and analytical protocols with examples from the Geological Survey of Canada
Authors: Bourdeau J E , Dyer R D
Published: July 2023

Regional-scale lake sediment surveys have been successfully used since the 1970s as a means for reconnaissance geochemical exploration. Lake sediment sampling is typically performed in areas with a lack of streams and an overabundance of small-sized (=5 km
across) lakes. Lake sediments are known to have major, minor and trace element concentrations that reflect the local geology. Overall, lake sediment surveys are planned and conducted following four distinct stages: 1) background research, 2) orientation survey, 3) regional survey, and 4) detailed
survey. At the Geological Survey of Canada, samples are usually collected from a helicopter with floats. Sample density ranges from 1 sample per 6 - 13 km2. Samples are collected from the centre of the lake using a gravity torpedo sampler which corresponds to a hollow-pipe, butterfly bottom-valved
sampler attached by a rope to the helicopter. Collected sediment samples are then placed in labelled bags and left to air dry. Detailed field notes and additional samples (field duplicates), for the purpose of an adequate quality assurance and quality control program, are also taken. Samples are
then milled and sent to analytical laboratories for element determination. Commonly used analytical methods include: X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and -mass spectrometry (ICP-MS), instrumental neutron
activation analysis (INAA), and/or determination of volatile compounds and organic carbon using Loss on Ignition (LOI). Analytical data is first evaluated for quality (contamination, accuracy and precision). Numerous options for the analysis of lake sediment data exist, ranging from simple basic
element concentration maps and statistical graphical displays together with summary statistics, to employing multivariate methodologies, and, more recently, using machine learning algorithms. By adopting the set of guidelines and examples presented in this manual, scientific researchers, exploration
geologists, geochemists and citizen scientists will be able to directly compare lake sediment datasets from anywhere in Canada.

Background:

The mortality rate of acute coronary syndrome (ACS) has significantly improved, but the recurrence rate has been increasing year by year, mainly due to the incomplete control of risk factors. According to clinical statistics, 80% of ACS patients are first-time sufferers and require self-management program for disease care and continuous support from professionals.

Objectives:

This study aimed to investigate the effect of self-management and readmission in patients with ACS with an intervention management program.

Methods:

This quasi-experimental study used purposive sampling. The study was performed from January 20, 2020 to December 31, 2021, and involved 97 cases. A case manager was used in the self-management program, using “the Chinese version of the Seattle Angina Questionnaire (SAQ)” and the self-made “acute coronary syndrome self-management questionnaire (ACS-SMQ)” before and after hospitalization and the post-hospitalization blood tests and medical records for each participant.

Results:

ACS-SMQ (F = 324.524, P < 0.001), low-density lipoprotein (LDL) levels (F = 34.428, P < 0.001), and hemoglobin A1c levels (F = 3.154, P = 0.048) were evaluated before and after the intervention program. The number of patients with LDL of <70 mg/dL increased from 12.4% to 23.7%, and participants with LDL levels of <100 mg/dL increased from 36.1% to 56.7% before and after the intervention, respectively. The readmission rate was 4.1% (4/97), 11.3% (11/97), and 3.1% (3/93) at 1, 6, and 12 months, respectively. The LDL level during hospitalization was negatively correlated with 1- (r = -0.236*, P < 0.05), 6- (r = −0.220*, P < 0.05), and 12-month readmission rates (r = −0.212*, P < 0.05) (* When P = 0.05 (two-tailed), the correlation was significant).

Conclusion:

The readmission of patients with ACS is associated with LDL levels during hospitalization. Therefore, an individualized intervention management program should be used to adjust the lifestyle of patients during hospitalization to control risk factors. If high-intensity statin therapy is used strictly according to the guidelines, patients may receive higher doses than they require if the guidelines are to be strictly followed, which will easily affect their medication compliance. The case manager is a clinical application that needs to be carefully considered.
An Unusual Complication of Infective Endocarditis Treated by Percutaneous Intervention
Authors: Abushahba Galal , Robinson Lana , Keelan Paul , Murphy Niamh F. , Bijjam Venu Reddy
Published: July 2023

Mycotic pseudoaneurysms (PA) are an infrequent complication of infective endocarditis (IE). However, due to advanced imaging modality and early therapy, this complication has been seen less frequently in the past few years. The reported incidence is 5%–15% of the patients, with the most common site being intracranial vessels (up to 65%), followed by abdominal and then peripheral vessels. We describe a young patient with a bicuspid aortic valve complicated by IE, who developed a giant mycotic PA. This was treated with a cover stent of the aneurysmal segment, which was complicated by distal stent migration and eventually managed with bypass surgery.

Published: July 2023

Background:

Cardiovascular disease patients are more likely to be readmitted within 30 days of being discharged alive. This causes an enormous burden on health-care systems in terms of poor care of patients and misutilization of resources.

Aims and Objective:

This study aims to find out the risk factors associated with 30-day readmission in cardiac patients at Heart Hospital, Qatar.

Methods:

A total of 10,550 cardiac patients who were discharged alive within 30 days at the heart hospital in Doha, Qatar, from January 2015 and December 2019 were analyzed. The bootstrap method, an internal validation statistical technique, was applied to present representative estimates for the population.

Results:

Out of the 10,550 cardiac patients, there were 8418 (79.8%) index admissions and 2132 (20.2%) re-admitted at least once within 30 days after the index admission. The re-admissions group was older than the index admission group (65.6 ± 13.2 vs. 56.0 ± 13.5,P= 0.001). Multinomial regression analysis showed that females were 30% more likely to be re-admitted than males (adjusted odds ratio [aOR] 1.30, 95% confidence interval [CI]: 1.11–1.50,P= 0.001). Diabetes (aOR 1.36, 95% CI: 1.20–1.53,P= 0.001), chronic renal failure (aOR 1.93, 95% CI: 1.66–2.24,P= 0.001), previous MI (aOR 3.22, 95% CI: 2.85–3.64,P= 0.001), atrial fibrillation (aOR 2.17, 95% C.I. : 1.10-2.67,P= 0.01), cardiomyopathy (aOR 1.72, 95% CI 1.47–2.02,P= 0.001), and chronic heart failure (aOR 1.56, 95% C.I.: 1.33-1.82,P= 0.001) were also independent predictors for re-admission in the regression model. C-statistics showed these variables could predict 82% accurately hospital readmissions within 30 days after being discharged alive.

Conclusion:

The model was more than 80% accurate in predicting 30-day readmission after being discharged alive. The presence of five or more risk factors was found to be crucial for readmissions within 30 days. The study may help design interventions that may result in better outcomes with fewer resources in the population.

Published: July 2023

ABSTRACT

Background:

An antenatal mother undergoes significant changes throughout pregnancy and most of which occur during the second trimester. Supplements are important for normal growth and development of fetus, Deficiency of supplements during pregnancy leads to anemia and can have a negative impact on perinatal and maternal outcomes. These complications can be prevented by supplementing needed vitamins and minerals.

Method:

A Quasi-experimental study was conducted on 137 subjects visiting gynecology OPD enrolled by total enumerative sampling technique. Hemoglobin level and the adherence of supplements were assessed during the second trimester of antenatal mothers in both the groups.

Results:

Adherence of supplements has increased significantly (p value = 0.005, 0.004, and 0.040 for iron, folic acid, and calcium, respectively) among subjects in the experimental group. Results of SMAQ shows that there is increase in adherent mothers from 33.3% to 71.2% experimental group.

Conclusion:

Supplement adherence kit was effective in increasing supplement adherence level along with an improvement in hemoglobin levels among antenatal mothers in the Experimental group.
Is there a relationship between the urinary iodine of pregnant and diabetic patients?
Authors: Öztürk Mine
Published: July 2023

ABSTRACT

Objectives:

We investigated the iodine status in this study in pregnant women, diabetic women–men, and nondiabetic men–women living in our region.

Methods:

A total of 385 cases who applied to the endocrine clinic between 2015 and 2020 were reviewed retrospectively. The gender, age, free T3 (pg/ml), free T4 (ng/dl), TSH (μIU/mL), anti-TPO antibody (IU/ml), anti-thyroglobulin antibody (IU/ml), and random urine iodine concentration (μg/L) levels of cases were recorded. The cases were grouped as pregnant, female, male, diabetic female, and diabetic male. Cases with overt thyroid disease, heart failure, liver failure, and kidney failure were excluded.

Results:

There were 6.75% (n = 26) pregnant, 54.8% (n = 211) nondiabetic female patients, 18.9% (n = 73) diabetic female patients, 12.7% (n = 49) nondiabetic male, and 4.15% (n = 16) diabetic male patients. The random urinary iodine level was significantly higher in nondiabetic women (112.9 ± 77.21) and diabetic women (140.7 ± 97.8) than in pregnant women (77.8 ± 31.8) (P = 0.00 and P = 0.03). There was no significant relationship between random urine levels of pregnant women and nondiabetic men (104.1 ± 82.6) (P = 0.16). The random urinary iodine level was significantly higher in diabetic men (170.0 ± 112.1) than in pregnant women (P = 0.00).

Conclusions:

In our region (xxx Region), pregnant women had iodine deficiency. The iodine level in men and women was very close to the lower limit. The urinary iodine level was higher in diabetic women and diabetic men than in both pregnant women and nondiabetic women and nondiabetic men. The results brought us the question: Could the high spot urinary iodine level in diabetic patients be a clue to nephropathy?

Published: July 2023

ABSTRACT

We describe the case of a young male presenting with hiccups refractory to antacids. Due to high index of suspicion was evaluated with a chest X-ray which revealed pericardial effusion. The effusion was drained, and the hiccups resolved. It is a teaching moment, to consider simple imaging, i.e., chest X-ray in patients with refractory hiccups to rule out more serious underlying causes.

Published: July 2023

Objective:

This study aimed to introduce trocar-assisted percutaneous abscess drainage (TA-PAD) and compare it to the Seldinger puncture with pigtail drain (SPD) in the clinical treatment of intra-abdominal abscess.

Materials and Methods:

The clinical data of 23 patients with abdominal abscess treated with TA-PAD from 2017 to 2019 were retrospectively analyzed. Moreover, 18 patients with abdominal abscess treated with SPD from 2014 to 2016 were taken as the control. The therapeutic effects were compared between the two groups.

Results:

No death or surgery-related complications were observed in either group. There were significant differences between the two groups in the drainage rate of open surgery, the complete healing time of abscess, the time of inflammation relief, the recurrence rate of abscess, and the hospitalization cost (P < 0. 05). There was no significant difference in the duration of antibiotic use between the two groups (P > 0. 05).

Conclusions:

TA-PAD can optimize the treatment of abdominal abscesses with significantly lower surgical drainage rates, shorter hospital stays, lower recurrence rates, and lower hospital costs.
Temporary arterial shunting following a complete transection of femoral artery in a resource-limited setting
Authors: Dieudonne Lemfuka A. , Kolleh J. Nutai , Gao Raisa R.
Published: July 2023

The aim of a surgeon managing vascular trauma in an extremity is to save the life, limb, and function of the patient. The use of temporary intravascular shunting has been shown to be a successful damage control strategy in patients who present with hemodynamic instability. We present the first reported case of a penetrating arterial injury of the lower limb causing a large defect that was successfully treated with temporary intravascular shunting before definitive repair in the country of Liberia. In a low-resource setting such as ours, the surgeon often opts to amputate limbs with vascular injuries that are not believed to be candidates for primary repair. Using a pediatric feeding tube with good postoperative results, we demonstrated that temporary arterial shunting in damage control situations before definitive repair was not only feasible but also cost-effective and ultimately resulted in the preservation of the patient’s limb.

In this paper, we establish a number of results about the topology of the leaves of a closed singular Riemannian foliation

(M,\mathcal{F})

. If

M

is simply connected, we prove that the leaves are finitely covered by nilpotent spaces, and characterize the fundamental group of the generic leaves. If

M

has virtually nilpotent fundamental group, we prove that the leaves have virtually nilpotent fundamental group as well.
