Resident Participation in International Surgical Missions is Predictive of Future Volunteerism in Practice
Authors: Tannan Shruti Chudasama , Gampper Thomas J 
Published: March 2015

Background Interest in global health and international mission trips among medical student and resident trainees is growing rapidly. How these electives and international mission experiences affect future practice is still being elucidated. No study has identified if participation in international surgical missions during residency is a predictor of participation in international surgical missions in practice after training completion.Methods All trainees of our plastic surgery residency program from 1990 to 2011, during the implementation of optional annual international surgical missions, were surveyed to determine if the graduate had gone on a mission as a resident and as a plastic surgeon. Data were compared between graduates who participated in missions as residents and graduates who did not, from 1990 to 2011 and 1990 to 2007.Results Of Plastic Surgery graduates from 1990 to 2011 who participated in international missions as residents, 60% participated in missions when in practice, versus 5.9% of graduates participating in missions in practice but not residency (P<0.0001). When excluding last 5 years, graduates participating in international missions in practice after doing so as residents increases to 85.7%, versus 7.41% who participate in practice but not residency P<0.002.Conclusions Results reveal plastic surgeons who participate in international surgical missions as residents participate in international surgical missions in practice at higher rates than graduates who did not participate in missions during residency. International missions have significant intrinsic value both to trainee and international communities served, and this opportunity should be readily and easily accessible to all plastic surgery residents nationwide.
Diagnostic accuracy of procalcitonin, interleukin-6 and interleukin-8 for predicting Gram-negative bacteremia in febrile neutropenia patients with acute lymphoblastic leukemia
Authors: Urbonas Vincas , Eidukaitė Audronė 
Published: March 2015

Background. Currently available biomarkers are not specific and sensitive enough for early detection of bacterial infection in patients with cancer who have febrile neutropenia. The objective of this study was to assess diagnostic accuracy of interleukin-6 (IL-6), interleukin-8 (IL-8) and procalcitonin (PCT) in the identification of Gram-negative bacteremia at the beginning of a febrile episode in pediatric oncology patients with acute lymphoblastic leukemia (ALL).
Methods. A total of 40 episodes of febrile neutropenia in 27 childhood cancer patients were enrolled in this study. Serum samples were collected at presentation after confirmation of febrile neutropenia and analyzed according to the recommendations of manufacturers. Patients were classified into Gram-negative bacteremia (GNB) and fever of unknown origin (FUO) groups.
Results. The median concentration of IL-6, IL-8 and PCT were higher in the GNB group compared to the FUO group (65.4 vs. 409.0 pg/ml, P = 0.0025; 166.0 vs. 883.0 pg/ml, P = 0.0002; 0.27 vs. 0.44 ng/ml, P = 0.0169, respectively). The areas under the curves (AUCs) for both IL-6 and IL-8 were 0.94 and 0.93, respectively, indicating that these cytokines discriminated patients with Gram-negative bacteremia with excellent accuracy, whereas PCT had lower diagnostic accuracy (AUC = 0.76).
Conclusions. IL-6 and IL-8 evaluation might be used as an additional diagnostic tool for the prediction of Gram-negative bacteremia in pediatric patients with ALL during febrile neutropenia episodes.
Mise à l’épreuve de la cartographie des concepts comme méthode intégrative d’identification et d’analyse d’un écosystème entrepreneurial
Authors: Cloutier L. Martin , Cueille Sandrine , Recasens Gilles 
Published: March 2015

Cet article présente la mise à l’épreuve de la cartographie des concepts comme méthode intégrative d’étude d’un écosystème entrepreneurial dans lequel des dirigeants-entrepreneurs de microentreprises et leurs accompagnateurs s’interrogent sur les actions à mettre en place pour dynamiser et densifier l’activité entrepreneuriale d’une région. La cartographie des concepts est une approche mixte (qualitative et quantitative) ascendante (bottom-up), participative et de groupe. Elle comprend des techniques de groupes de discussions et d’analyses statistiques multivariées (analyse d’échelonnement multidimensionnel, classification ascendante hiérarchique). Les participants, dirigeants-entrepreneurs (n = 25) et accompagnateurs (n = 12), ont classé par piles d’idées semblables et coté l’importance et la faisabilité de 82 énoncés d’actions. La carte des concepts obtenue constitue une représentation systémique partagée d’interrelations et d’interdépendances complexes entre les domaines d’intervention qui composent l’écosystème entrepreneurial à l’étude. La mise en place de cette démarche permet d’établir un certain nombre de constats, sur trois plans, quant à sa pertinence dans l’étude d’un écosystème entrepreneurial. Au plan conceptuel, les résultats montrent leur adéquation avec le cadre d’analyse de l’écosystème entrepreneurial de référence et la possibilité de semi-régularités empiriques permettant la généralisation des résultats. Au plan théorique, les construits latents obtenus de la carte des concepts peuvent aider à approfondir les réflexions au sujet des variables endogènes et des facteurs exogènes liés à ces actions. La mise à l’épreuve de la cartographie des concepts apporte également une contribution au plan managérial, puisqu’elle permet de mesurer l’importance et la faisabilité perçue des actions proposées. L’ensemble de ces résultats apporte une meilleure compréhension des grands thèmes d’actions que les dirigeants, au sein de leur microentreprise, et les accompagnateurs au service du développement entrepreneurial, peuvent mettre en place.
Les leviers sociaux de la réussite entrepreneuriale

Published: March 2015

Le capital social constitue un outil pertinent non seulement pour développer le réseau de relations sociales que détient l’entrepreneur avec les parties prenantes clés au développement de son entreprise nouvellement créée, mais également pour favoriser son accès aux ressources externes stratégiques, à savoir le financement et les informations requises.Or, la rareté des recherches consacrées aux antécédents du capital social entrepreneurial nous a interpellées et amenées à tenter d’approfondir notre appréhension du processus par lequel l’entrepreneur pourrait contribuer à faire perdurer son entreprise nouvelle. Il serait donc judicieux de porter une attention particulière aux facteurs qui sont susceptibles de faciliter la formation et le développement du capital social entrepreneurial.Une étude menée auprès de 120 entrepreneurs de sociétés de services et d’ingénierie informatique (SSII) tunisiennes illustre le rôle que jouent les compétences sociales de l’entrepreneur dans le développement d’un capital social (découlant d’un réseau étendu, de relations riches en liens faibles et non redondants) propice à un accès plus facile aux informations et au financement requis. Ces compétences sociales renferment le management de l’impression via la valorisation d’autrui, la persuasion sociale et l’intelligence émotionnelle de soi.
La détermination de l’employeur véritable après la décision Ville de Pointe-Claire
Authors: Fontaine Laurence Léa 
Published: March 2015

Divers éléments, tels que l’exacerbation de la concurrence ou encore l’influence des nouvelles technologies, produisent des transformations liées au capitalisme néolibéral, celui-ci offrant une place de choix au marché économique. Concrètement, ces profondes transformations du travail entraînent flexibilité, précarisation et mobilité de la main-d’oeuvre, ce qui conduit à l’émergence du travail atypique sous diverses nouvelles catégories d’emploi, dont celles qui permettent d’externaliser la main-d’oeuvre. Le recours à l’intermédiation, et plus particulièrement au travail temporaire par l’entremise d’agences de location de personnel, s’inscrit dans une logique néolibérale qui ignore l’intensité du rapport de force opposant employeur et travailleuses et travailleurs. Le salarié embauché par une agence de location de personnel est mis au service d’une entreprise cliente : l’emploi temporaire participe alors à l’instauration d’une relation de nature tripartite, non prévue par le Code du travail. Cette dernière peut entraîner dans l’esprit du travailleur une certaine confusion sur la question de savoir qui est son véritable employeur. D’un point de vue juridique, connaître l’identité du véritable employeur est cruciale pour l’application de différentes lois ayant pour objet le bien-être de la main-d’oeuvre. Ensuite, de la loi applicable découle un ensemble de droits et d’obligations s’imposant aux parties. Le texte qui suit concerne précisément les relations collectives de travail et l’accès à la représentation collective par les travailleuses et travailleurs. Le coeur de l’analyse consiste à mettre en lumière les différents critères permettant la détermination de l’identité du véritable employeur du plaignant. Aux termes de l’approche souple et globale mise au point par la Cour suprême du Canada dans la décision Ville de Pointe-Claire, le véritable employeur est celui qui a le plus de contrôle sur tous les aspects du travail du salarié selon la situation factuelle particulière à chaque affaire. Le critère essentiel dans la détermination du véritable employeur réside en fait dans le contrôle fondamental des conditions de travail, ce qui implique l’analyse d’un ensemble de facteurs, aussi appelés « attributs ». La jurisprudence postérieure à la décision Ville de Pointe-Claire est variée et est classée selon différentes tendances : les critères utilisés pour déterminer le véritable employeur sont les mêmes que dans cette décision de la Cour suprême, ou ne le sont pas nécessairement ; des critères apparaissent, tandis que d’autres sont écartés.

Published: March 2015

Abstract:This study aims to assess physical and social environments as determinants of customer experiences with regard to guest satisfaction and intentions to revisit Malaysian resort hotels. It examines a research framework constituting physical and social environment and analyses the results of the survey to test the hypotheses. Questionnaires were distributed to customers of resort hotels at Langkawi, Malaysia that were selected using convenience sampling. The data collected were analysed using partial least squares based structural equation modelling (PLS-SEM). The findings reveal that physical and social environments are good predictors of customer satisfaction and revisit intentions. The results also indicate that customer satisfaction contribute positively to revisit intentions. The implications and limitations of the study are also discussed.
Flora of Mt. Mantalingahan Range, Palawan Island, Philippines: Basis for Prioritizing Protected Areas
Authors: SOPSOP LITA B. , SOPSOP GLENN O. 
Published: March 2015

In Palawan Island, Philippines, Mt. Mantalingahan is given high conservation value because its varied habitats harbor different organisms including important wildlife, but little is known about its floristic composition. Using the Variable Transect Method for Rapid Assessment of Tropical Plant Communities, its peripheral forest flora in four surrounding municipalities was surveyed to describe the community structure and assess the priority areas for protection. The mountain’s peripheral forest is rich in diversified flora having at least 351 species in 214 genera and 92 families. Endemism is remarkably high having at least 50 species of which nine are only found in Palawan, higher than the six species found in Puerto Princesa City Underground River National Park. It contains numerous plant species that are rare with narrow habitat range, economically important, and 13 vulnerable, four endangered and five critically endangered. From the criteria in prioritizing areas for protection, Rizal municipality ranked first, followed by Bataraza, Sofrono Española, and Brooke’s Point municipalities. Results from rapid floral assessment demonstrate that Mt. Mantalingahan Range is one of the most important sites in Palawan Corridor for biodiversity conservation. The best and strictest measures should be applied to prevent any degradation of such a rich genetic resource.

A wide voltage range non‐isolated continuous input buck‐boost converter for optimal green energy harvesting in LED lighting systems
Authors: Kanithi Ashok Kumar , B L Narasimharaju 
Published: August 2024

AbstractThis article introduces a wide input range buck‐boost Light Emitting Diode (LED) driver designed for industrial and street lighting applications. The driver characterized by a continuous input current with less ripple and common ground between input and output featuring non‐inverting voltage at the output, suitable for green energy sources. The proposed topology achieves a high voltage conversion ratio which is a blend of quasi‐Z source boosting followed by conventional buck with enhanced step‐down voltage capability. Furthermore, the driver maintains a constant voltage at the load terminal for diverse source voltage variations by adapting the inherent buck‐boost nature. Also, the driver operates with low duty ratio results in lower voltage, current stresses and conduction losses. The steady state and design analysis of the proposed LED driver is carried out for an input voltage range from 24 to 96 V. An experimental prototype of 200 W/71 V LED driver is validated in the laboratory for wide input voltage. There is a high concordance exists between the theoretical analysis and experimental results of the proposed topology.
Implications of Developmental 17‐OHPC Exposure on the Mesocorticolimbic Serotonergic and Dopaminergic Pathways and Adolescent Mood–Related Behavior in Rats
Authors: Graney Paige L. , Sarno Evelyn L. , Miller Jessie E. , Wagner Christine K. 
Published: August 2024

ABSTRACTThe synthetic progestin, 17‐α‐hydroxyprogesterone caproate (17‐OHPC), is administered to pregnant individuals at risk for recurrent preterm birth during a critical period of fetal mesocorticolimbic serotonergic and dopaminergic pathway development. These pathways play an important role in regulating cognitive behaviors later in life. Despite this, there has been very little research regarding the potential long‐term effects of 17‐OHPC on the behavioral and neural development of exposed children. In rodents, developmental exposure to 17‐OHPC disrupts serotonergic and dopaminergic innervation of the medial prefrontal cortex and impairs decision‐making in complex cognitive tasks in adulthood. The present study tested the hypothesis that developmental exposure to 17‐OHPC similarly disrupts the development of serotonergic and dopaminergic pathways within limbic targets and subsequent mood‐related behaviors. Developmental 17‐OHPC exposure significantly increased the density of serotonin transporter–IR fibers in CA1, CA2/3, and the suprapyramidal blade of dentate gyrus in hippocampus and significantly reduced the density of TH‐IR fibers within the nucleus accumbens shell in males but had no effect in females during adolescence. Irregular microglia activational phenotype and number were also observed in the hippocampus of 17‐OHPC‐exposed males. Developmental 17‐OHPC reduced the latency to immobility in males in the forced swim test but did not affect sucrose consumption in a sucrose preference test. These findings suggest that 17‐OHPC exerts sex‐specific effects on the development of mesocorticolimbic pathways and mood‐related behavior in adolescence and highlight the need to investigate effects in adolescent children.

AbstractWild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating physicians, approximately one‐third of patients with ATTRwt‐CM are initially misdiagnosed with other cardiac diseases. Although heart failure (HF) is the most common initial manifestation of ATTRwt‐CM, observed in nearly 70% of affected patients, patients may also present with other cardiologic symptoms, such as atrial fibrillation (AF) and aortic stenosis (AS). This non‐specific and diverse nature of the initial ATTRwt‐CM presentation indicates that various cardiology subspecialties are involved in patient diagnosis and management. Standard guideline‐directed pharmacological treatment for HF is not recommended for patients with ATTRwt‐CM because of its limited effectiveness. However, no established algorithms are available regarding HF management in this patient population. This literature review provides an overview of the red flags for ATTRwt‐CM and research findings regarding HF management in this patient population. In addition to commonly recognized red flags for ATTRwt‐CM (e.g., HF, AF and severe AS), published literature identified potential red flags such as coronary microvascular dysfunction. For HF management in patients with ATTRwt‐CM, the use of mineralocorticoid receptor antagonists (MRAs) was reported as a well‐tolerated option associated with a low discontinuation rate and reduced mortality. Although there is no concrete evidence for recommendations against sodium‐glucose cotransporter 2 inhibitor (SGLT2i) administration, research supporting its use is limited to small‐scale studies. Robust evidence is lacking for AF ablation, implantable cardioverter‐defibrillators and cardiac resynchronization therapy. Based on the published findings and our clinical experience as Japanese ATTRwt‐CM experts, red‐flag symptom clusters for each cardiology specialty (HF, arrhythmia and ischaemia/structural heart disease) and a treatment scheme for HF management are presented. As this research area remains at an exploratory stage, our observations would require further discussion among experts worldwide.

ZusammenfassungAus dem Mio‐Pliozän von West‐Juva wird ein fossiles Cuttiferen‐Holz beschrieben, das dem rezenten Calophyllum spectabile Willd, nahesteht, aber auch zu Mesua ferrea L. gewisse Beziehungen hat : Calophylloxylon intermedium sp. nov. Die bisher beschriebenen fossilen Guttiferen‐Hölzer werden kritisch betrachtet; sie gehören zu den Gattungen Calophylloxylon Lakhantal & Awasthi, Kayeoxylon Chowdhury & Tandan, Mesuoxylon Lakhanpal & Awasthi und Symphonioxylon Chiarugi (Syn. Guttiferoxylon Kräusel). Ihre Fundorte liegen innerhalb des Verbreitungsgebietes der rezenten Vergleichsgattungen; aus dem Tertiär von Österreich und Algerien beschriebene angebliche Guttiferen‐Hölzer sind keine sicheren Belege für das Vorkommen der Familie.
Statistical Properties of GinSE and Elliptic GinSE
Authors: Byun Sung-Soo , Forrester Peter J. 
Published: August 2024

AbstractEigenvalues of GinSE matrices occur in complex conjugate pairs as for complex GinOE eigenvalues, but now with zero probability of an eigenvalue being real. Also in common with complex GinOE eigenvalues is that the GinSE eigenvalues form a Pfaffian point process, and that their PDF admits a Coulomb gas interpretation with image terms. While the determination of the required skew-orthogonal polynomials is straightforward, the particular form gives a new challenge in relation to analysing the various scaling limits. This is overcome by making use of a certain inhomogeneous partial differential equation satisfied by the pre-kernel. Such an approach carries over to the analysis of a weakly non-Hermitian regime. Also contained in this chapter is the large N analysis of the partition function and gap probability associated with GinSE eigenvalues, and results relating to the singular values and eigenvectors. Furthermore, a study is undertaken of an elliptic generalisation, which interpolates between GinSE and Hermitian GSE matrices.

ZusammenfassungWährend der Kommissionsentwurf zur KI-VO die Rechtspositionen der betroffenen Personen praktisch komplett ausblendete, enthält der verabschiedete Normtext einen deutlich stärkeren Fokus in dieser Richtung und führt insbesondere zwei neue Betroffenenrechte ein. Angesichts der Grundrechtsrelevanz vieler KI-Systeme ist dies zu begrüßen; die konkrete Umsetzung führt allerdings zu neuen Fragen sowohl in der Binnensystematik der KI-VO als auch im Verhältnis zur DS-GVO.

Assessment of Hungarian large cities readiness in adopting electric bike sharing system
Authors: Jaber Ahmed , Csonka Bálint 
Published: August 2024

AbstractThis study explores the readiness of eight large Hungarian cities to adopt electric bike sharing systems as a sustainable transportation mode. By assessing 25 indicators related to infrastructure, safety, demographics, legislation, and transportation systems, we comprehensively understand each city's current situation and readiness level. By engaging experts, we derived weighted scores for key indicators to provide a comprehensive analysis of each city's potential. The results reveal varied readiness across cities, offering targeted insights for policymakers to enhance urban mobility sustainably. Our analysis reveals that certain cities, such as Budapest and Gyor, are better prepared for sustainable transportation than others. However, every city has positive and negative aspects that must be considered. Establishing infrastructure for cycling and connectivity to public transportation systems should be prioritized in Hungarian cities. Additionally, safety action plans should be implemented to address road safety concerns. Promoting cycling culture and electric vehicles is also essential to encourage the adoption of sustainable transportation modes. The findings of this research offer valuable insights to policymakers, urban planners, and researchers interested in promoting sustainable mobility.
