Reflexiones en torno a la ecoética y sus aportes en la época contemporánea
Authors: Gómez Arévalo José Arlés 
Published: October 2015

<p>El presente artículo hace parte de la investigación adelantada por el Grupo Ciencia-Espiritualidad, que en su tercera fase denominada “Ecología-salud-formación integral”. Se realiza una aproximación epistémica a las potenciales correspondencias entre el pensamiento occidental y los grandes metarrelatos del lejano Oriente, con relación a los fundamentos de la ecoética, ciencia emergente, lo que responde en gran medida –en la complejidad del mundo contemporáneo– a los profundos desafíos en materia de objetivación de una nueva mirada sobre el hombre en su interrelación armónica con la naturaleza y el universo.</p>
Aproximación a una cartografía conceptual de la biopolítica
Authors: Martínez posada Jorge Eliecer , Guarín Salazar Yudy Alejandra 
Published: October 2015

<p>Cuando nos referimos a la noción de biopolítica podemos percibir que se refiere a la idea de una política de vida (Castro, 2011, p. 15) que se manifiesta en el control de la conducta humana, así como en la construcción de supuestos de verdad, la moralidad de la sociedad. De la biopolítica existen diferentes concepciones genealógicas que posibilitan el debate y la reflexión sobre su concepto. Por esa razón, el presente escrito tiene como propósito analizar y contrastar los aportes de Michel Foucault, Giorgio Agambem y Roberto Espósito, quienes han realizado una elaboración teórica que permite complejizar y evidenciar las diferencias entre autores, además de analizar cómo de la vida (el bíos) se ocupa la Bioética, como protección de cada ser humano en su integridad.</p>
Estimation of coefficients of multivariable power series approximating magnetic nonlinearity of AC machines
Authors: Sobczyk Tadeusz J. , Warzecha Adam 
Published: October 2015

Abstract
Energy based approach was used in the study to formulate a set of functions approximating the magnetic flux linkages versus independent currents. The simplest power series that approximates field co-energy and linked fluxes for a two winding core of an induction machine are described by a set of common unknown coefficients. The authors tested three algorithms for the coefficient estimation using Weighted Least-Squared Method for two different positions of the coils. The comparison of the approximation accuracy was accomplished in the specified area of the currents. All proposed algorithms of the coefficient estimation have been found to be effective. The algorithm based solely on the magnetic field co-energy values is significantly simpler than the method based on the magnetic flux linkages estimation concept. The algorithm based on the field co-energy and linked fluxes seems to be the most suitable for determining simultaneously the coefficients of power series approximating linked fluxes and field co-energy.
Transient recovery voltage analysis for various current breaking mathematical models: shunt reactor and capacitor bank de-energization study
Authors: Oramus Piotr , Chmielewski Tomasz , Kuczek Tomasz , Piasecki Wojciech , Szewczyk Marcin 
Published: October 2015

Abstract
Electric arc is a complex phenomenon occurring during the current interruption process in the power system. Therefore performing digital simulations is often necessary to analyse transient conditions in power system during switching operations. This paper deals with the electric arc modelling and its implementation in simulation software for transient analyses during switching conditions in power system. Cassie, Cassie-Mayr as well as Schwarz-Avdonin equations describing the behaviour of the electric arc during the current interruption process have been implemented in EMTP-ATP simulation software and presented in this paper. The models developed have been used for transient simulations to analyse impact of the particular model and its parameters on Transient Recovery Voltage in different switching scenarios: during shunt reactor switching-off as well as during capacitor bank current switching-off. The selected simulation cases represent typical practical scenarios for inductive and capacitive currents breaking, respectively.
Interrogation zone determination in HF RFID systems with multiplexed antennas
Authors: Jankowski-Mihułowicz Piotr , Węglarski Mariusz 
Published: October 2015

Abstract
The operation of an anti-collision RFID system is characterized by the interrogation zone which should be estimated in any direction of 3D space for a group of electronic transponders. The interrogation zone should be as large as possible. However, the many problems in this area are due to the fact that energy can be transferred to transponders only on a limited distance. The greatest flexibility in developing RFID applications and shaping the interrogation zone can be achieved using the system with an antenna multiplexer. Therefore the problem of the interrogation zone determination in HF RFID systems with two orthogonal RWD antennas is presented in the paper. The perceived issues have been effectively dealt with and the solution has been proposed on the basis of the elaborated model. Conducted studies have been used to develop the software tool JankoRFIDmuxHF in the Mathcad environment. The research results are analysed in an example system configuration. The specialized measuring stand has been used for experimental verification of the identification efficiency. The convergence of the measurements and calculations confirms a practical usefulness of the presented concept of interrogation zone determination in anti-collision systems. It also shows the practical utility of the developed model and software tools.
Alcohol and mortality after moderate to severe traumatic brain injury: a meta-analysis of observational studies
Authors: Raj Rahul , Mikkonen Era D. , Siironen Jari , Hernesniemi Juha , Lappalainen Jaakko , Skrifvars Markus B. 
Published: October 2015

OBJECT
Experimental studies have shown numerous neuroprotective properties of alcohol (“ethanol”) after TBI, but clinical studies have provided conflicting results. The authors aimed to assess the relationship between positive blood alcohol concentration (BAC) on hospital admission and mortality after moderate to severe traumatic brain injury (TBI).

METHODS
The authors searched 8 databases for observational studies reported between January 1, 1990, and October 7, 2013, and investigated the effect of BAC on mortality after moderate to severe TBI. Reviews of each study were conducted, and data were extracted according to the MOOSE and PRISMA guidelines. Study quality was assessed using the Newcastle-Ottawa scale. The Mantel-Haenszel fixed effect methodology was used to generate pooled estimates. Heterogeneity was dealt with by multiple sensitivity analyses.

RESULTS
Eleven studies with a total of 95,941 patients (42% BAC positive and 58% BAC negative) were identified for the primary analysis (overall mortality 12%). Primary analysis showed a significantly lower risk of death for BAC-positive patients compared with BAC-negative patients (crude mortality 11.0% vs 12.3%, pooled OR 0.84 [95% CI 0.81–0.88]), although flawed by heterogeneity (I2 = 68%). Multiple sensitivity analyses, including 55,949 and 51,772 patients, yielded similar results to the primary analysis (crude mortality 12.2% vs 14.0%, pooled OR 0.87 [95% CI 0.83–0.92] and crude mortality 8.7% vs 10.7%, pooled OR 0.78 [95% CI 0.74–0.83]) but with good study homogeneity (I2 = 36% and 14%).

CONCLUSIONS
Positive BAC was significantly associated with lower mortality rates in moderate to severe TBI. Whether this observation is due to selection bias or neuroprotective effects of alcohol remains unknown. Future prospective studies adjusting for TBI heterogeneity is advocated to establish the potential favorable effects of alcohol on outcome after TBI.

OBJECT
The ClearPoint real-time interventional MRI-guided methodology for deep brain stimulation (DBS) lead placement may offer advantages to frame-based approaches and allow accurate implantation under general anesthesia. In this study, the authors assessed the safety and efficacy of DBS in Parkinson’s disease (PD) using this surgical method.

METHODS
This was a prospective single-center study of bilateral DBS therapy in patients with advanced PD and motor fluctuations. Symptom severity was evaluated at baseline and 12 months postimplantation using the change in Unified Parkinson’s Disease Rating Scale (UPDRS) Part III “off” medication score as the primary outcome variable.

RESULTS
Twenty-six PD patients (15 men and 11 women) were enrolled from 2010 to 2013. Twenty patients were followed for 12 months (16 with a subthalamic nucleus target and 4 with an internal globus pallidus target). The mean UPDRS Part III “off” medication score improved from 40.75 ± 10.9 to 24.35 ± 8.8 (p = 0.001). “On” medication time without troublesome dyskinesia increased 5.2 ± 2.6 hours per day (p = 0.0002). UPDRS Parts II and IV, total UPDRS score, and dyskinesia rating scale “on” medication scores also significantly improved (p < 0.01). The mean levodopa equivalent daily dose decreased from 1072.5 ± 392 mg to 828.25 ± 492 mg (p = 0.046). No significant cognitive or mood declines were observed. A single brain penetration was used for placement of all leads, and the mean targeting error was 0.6 ± 0.3 mm. There were 3 serious adverse events (1 DBS hardware-related infection, 1 lead fracture, and 1 unrelated death).

CONCLUSIONS
DBS leads placed using the ClearPoint interventional real-time MRI-guided method resulted in highly accurate lead placement and outcomes comparable to those seen with frame-based approaches.
Vasospasm on transcranial Doppler is predictive of delayed cerebral ischemia in aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis
Authors: Kumar Gyanendra , Shahripour Reza Bavarsad , Harrigan Mark R. 
Published: October 2015

OBJECT
The impact of transcranial Doppler (TCD) ultrasonography evidence of vasospasm on patient-centered clinical outcomes following aneurysmal subarachnoid hemorrhage (aSAH) is unknown. Vasospasm is known to lead to delayed cerebral ischemia (DCI) and poor outcomes. This systematic review and meta-analysis evaluates the predictive value of vasospasm on DCI, as diagnosed on TCD.

METHODS
MEDLINE, Scopus, the Cochrane trial register, and clinicaltrials.gov were searched through September 2014 using key words and the terms “subarachnoid hemorrhage,” “aneurysm,” “aneurysmal,” “cerebral vasospasm,” “vasospasm,” “transcranial Doppler,” and “TCD.” Sensitivities, specificities, and positive and negative predictive values were pooled by a DerSimonian and Laird random-effects model.

RESULTS
Seventeen studies (n = 2870 patients) met inclusion criteria. The amount of variance attributable to heterogeneity was significant (I2 > 50%) for all syntheses. No studies reported the impact of TCD evidence of vasospasm on functional outcome or mortality. TCD evidence of vasospasm was found to be highly predictive of DCI. Pooled estimates for TCD diagnosis of vasospasm (for DCI) were sensitivity 90% (95% confidence interval [CI] 77%–96%), specificity 71% (95% CI 51%–84%), positive predictive value 57% (95% CI 38%–71%), and negative predictive value 92% (95% CI 83%–96%).

CONCLUSIONS
TCD evidence of vasospasm is predictive of DCI with high accuracy. Although high sensitivity and negative predictive value make TCD an ideal monitoring device, it is not a mandated standard of care in aSAH due to the paucity of evidence on clinically relevant outcomes, despite recommendation by national guidelines. High-quality randomized trials evaluating the impact of TCD monitoring on patient-centered and physician-relevant outcomes are needed.

Published: October 2015

OBJECT
The relationship between headaches, pituitary adenomas, and surgical treatment of pituitary adenomas remains unclear. The authors assessed the severity and predictors of self-reported headaches in patients referred for surgery of pituitary adenomas and evaluated the impact of endoscopic transsphenoidal surgery on headache severity and quality of life (QOL).

METHODS
In this prospective study, 79 patients with pituitary adenomas underwent endoscopic transsphenoidal resection and completed the Headache Impact Test (HIT-6) and the 36-Item Short Form Health Survey (SF-36) QOL questionnaire preoperatively and at 6 weeks and 6 months postoperatively.

RESULTS
Preoperatively, 49.4% of patients had mild headache severity, 13.9% had moderate severity, 13.9% had substantial severity, and 22.8% had intense severity. Younger age and hormone-producing tumors predisposed greater headache severity, while tumor volume, suprasellar extension, chiasmal compression, and cavernous sinus invasion of the pituitary tumors did not. Preoperative headache severity was found to be significantly associated with reduced scores across all SF-36 QOL dimensions and most significantly associated with mental health. By 6 months postoperatively, headache severity was reduced in a significant proportion of patients. Of the 40 patients with headaches causing an impact on daily living (moderate, substantial, or intense headache), 70% had improvement of at least 1 category on HIT-6 by 6 months postoperatively, while headache worsened in 7.6% of patients. The best predictors of headache response to surgery included younger age, poor preoperative SF-36 mental health score, and hormone-producing microadenoma.

CONCLUSIONS
The results of this study confirm that surgery can significantly improve headaches in patients with pituitary adenomas by 6 months postoperatively, particularly in younger patients whose preoperative QOL is impacted. A larger multicenter study is underway to evaluate the long-term effect of surgery on headaches in this patient group.

Authors: Eva SN , Mollah GM , Sunyal DK , Zinnat R 
Published: October 2015

The aim of the observational case control study was to find out the association of type 2 diabetes mellitus (T2DM) with serum adiponectin level in Bangladeshi population. This was conducted in the Biomedical Research Group, Research Division, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM), Dhaka, Bangladesh. Sixty six T2DM subjects and seventy four healthy control subjects were included. Diabetes was diagnosed and classified as per World Health Organization criteria. Serum adiponectin was measured by Enzyme Linked Immunosorbent Assay (ELISA) method. Serum glucose was measured by glucose-oxidase method; serum insulin was measured by chemiluminescence- based ELISA technique. The insulin secretory capacity (HOMA%B), insulin sensitivity (HOMA%S) & insulin resistance (HOMA-IR) were assayed by homeostasis model assessment method. Statistical analysis was performed using SPSS Windows version 11.5. The median (range) fasting serum insulin of control and T2DM subjects were 14.7 (1.9-45.9) and 18.1 (4.1-42.8), respectively. The median (range) serum adiponectin (?g/ml) of the control and T2DM subjects were 8.7 (0.8-16.0) and 6.2 (1.1-22.4). The serum adiponectin of T2DM was significantly lower than the control subjects (p < 0.001). The median (range) HOMA%B values of control and T2DM subjects were 160.1 (33.4-493.4) and 100.5 (17.7-349.3), respectively. The median HOMA%B of T2DM subjects was significantly lower than the control subjects (p < 0.001). The median (range) HOMA%S values of control and T2DM subjects were 44.2 (9.8-339.4) and 32.8 (14.3-154.7), respectively. The median HOMA%S of T2DM group was significantly lower than the control subjects (p < 0.05). The median (range) HOMA-IR of control and T2DM subjects were 3.5 (0.5-11.4) and 5.8 (1.0-28.3), respectively. The median HOMA-IR of T2DM subjects was significantly higher than the control subjects (p < 0.001). The results of the study suggest that T2DM subjects have both insulin secretory defects, insulin resistance and associated with lower serum adiponectin level in Bangladeshi population.Mediscope Vol. 2, No. 2: July 2015, Pages 16-21
Modération et sobriété chez les étudiants : entre ethos de vie et résistance aux normes
Authors: Gaussot Ludovic , Palierne Nicolas , Le Minor Loïc 
Published: October 2015

Les recherches sur l’alcool se centrent sur la consommation effective, souvent les « conduites à risque », surtout lorsqu’elles portent sur les populations jeunes. Les abstinents ou faibles consommateurs ont très peu fait l’objet d’investigation approfondie. Cette étude qualitative porte sur un corpus d’une trentaine d’étudiants « sobres » ayant participé à un entretien approfondi et dégage quatre dimensions centrales de la définition et de l’identification comme quasi « non-buveur » : l’absence de plaisir gustatif, l’absence de recherche d’effets psychotropes majeurs et de la perte de contrôle, le refus de faire de l’alcool l’ingrédient indispensable de la fête, la valorisation d’un mode de sociabilité spécifique. Ce type de recherche montre l’intérêt d’étudier les processus de construction et de maintien dans un mode de « consommation sobre », voire abstinent, y compris pour mieux comprendre les modes de consommation « plus engagés » dans le boire.
Vers un leadership partagé à l’hôpital pour une GRH plus éthique
Authors: Miremont Marie-Claude , Valax Marc 
Published: October 2015

Notre recherche vise à intégrer l’éthique managériale et un leadership partagé qui permettraient à l’hôpital de sortir de la dynamique délétère dans laquelle il semble verser et d’évoluer vers une dynamique performante dans sa gestion des ressources humaines. À travers une étude empirique longitudinale sur quatre ans au sein de deux établissements hospitaliers du sud de la France, nous chercherons à mieux comprendre la situation de mutation que traverse aujourd’hui l’hôpital et à fixer des voies possibles d’un renouvellement des pratiques managériales.
Travailler pour une banque qui appartient à ses clients sociétaires : ça change quoi ? analyse de l’identité de marque employeur des banques coopératives
Authors: Guillot-Soulez Chloé , Soulez Sébastien 
Published: October 2015

Depuis la crise financière, la différence de statut est devenue un élément différenciant dans la stratégie de communication des banques coopératives. Cette différence se retrouve-t-elle quand elles communiquent sur leur marque employeur ? Cet article étudie l’identité de marque employeur des banques coopératives et la compare à celle des banques non-coopératives à partir des sites institutionnels de recrutement des principaux acteurs du secteur bancaire français. Les résultats montrent notamment que les différentes banques sont proches lorsqu’elles communiquent sur les attributs organisationnels et symboliques et sur les bénéfices fonctionnels de la marque employeur. Dans ce cas, les différences observées ne relèvent pas du statut (coopératif ou non) mais correspondent à des spécificités mises en avant par chacune des banques. Les différences en fonction du statut sont en revanche plus marquées pour les bénéfices économiques et psychologiques de la marque employeur. Leur statut particulier apparaît alors comme un élément différenciant pour les banques coopératives et les principes coopératifs leur permettent de se distinguer des banques capitalistes. Au final, il semble néanmoins difficile d’évoquer l’existence d’une « marque employeur coopérative » en référence à l’identité coopérative.
Les scop relèvent-elles d’un modèle de GRH homogène ? enseignements d’une recherche de terrain
Authors: Juban Jean-Yves 
Published: October 2015

À partir de l’analyse des pratiques de GRH sous l’angle des conventions que proposent Pichault et Nizet (2013), nous tenterons de savoir si les Scop (Sociétés Coopératives et Participatives) sont porteuses d’un modèle original et homogène de GRH. Nous le ferons à partir de l’étude de la gestion des emplois, des pratiques de recrutement et de rémunération que nous avons pu observer au sein d’une cinquantaine de Scop de la région Rhône-Alpes. L’hypothèse de cette communication met l’accent sur la convention délibérative dans la mesure où elle désigne des pratiques de GRH « faiblement verticales » (Pichault & Nizet, 2013, p. 85), et où elle prévoit des débats entre salariés sur la part de l’autonomie individuelle et collective par rapport à celle qui sera régie par des procédures qu’ils auront eux-mêmes mises au point. Nos résultats montrent que la GRH dans les Scop est fortement inspirée par les valeurs coopératives, mais ne correspond pas pleinement à la convention valorielle. La convention délibérative apparaît sur plusieurs dimensions de la GRH, il semble donc que la force du groupe l’emporte sur les tendances individualisantes.
Quand le territoire s’organise pour attirer à l’international et fidéliser en local les talents : le cas du cluster technologique de Sophia Antipolis
Authors: Loufrani-Fedida Sabrina , Saint-Germes Ève 
Published: October 2015

Dans l’économie actuelle, le management des talents est de plus en plus considéré comme la clé pour conquérir un avantage concurrentiel soutenable. Dans la littérature émergente sur le management global des talents, qui s’intéresse notamment aux processus et pratiques de management mis en place par les entreprises multinationales pour attirer, développer et fidéliser les collaborateurs talentueux, deux perspectives de recherche retiennent l’attention des chercheurs. La première a trait aux différents niveaux d’analyse (individuel, organisationnel et institutionnel/sociétal) des pratiques de management global des talents. La seconde cherche à comprendre comment les processus et pratiques de management des talents opèrent dans différents contextes (nationaux, internationaux et sectoriels). Dans cet article, nous proposons d’ouvrir une troisième perspective de recherche, au confluent des deux premières : celle du management global des talents par le territoire. Notre recherche, de type exploratoire, repose sur une démarche qualitative centrée sur l’étude d’un cas unique : le cluster technologique de Sophia Antipolis et sa plateforme numérique eDRH. L’analyse de ce cas nous permet d’expliquer, d’une part, les enjeux pour ce territoire de l’attractivité des talents à l’international et de leur fidélisation en local et, d’autre part, de comprendre la mise en place progressive d’une démarche collaborative inter-organisationnelle au sein du cluster pour répondre à ces enjeux, notamment grâce au rôle majeur joué par la plateforme numérique dans les transferts de pratiques de management des talents.
Les chemins escarpés de la négociation conventionnelle 2016
Authors: Grass Étienne 
Published: October 2015

Dans son sens premier, négocier signifie « faire du commerce » (du latin negotiari ). Le mot s’est enrichi avec le temps d’origines anglo-saxonnes. Il signifie également « venir à bout d’un obstacle ». La négociation de la convention médicale illustre ces deux sémantiques. On négocie la convention médicale comme on troque un tapis. On la négocie aussi comme on franchit un virage difficile. Négocier suppose un partenaire, un calendrier, la volonté réciproque de parvenir à un accord et souvent une mise en scène qui permet de justifier que chacun s’éloigne peu à peu des positions qu’il avait initialement dessinées. Tout cela fait encore défaut alors que la négociation devrait s’ouvrir.
