L’émergence et l’opérationnalisation d’une logique d’action responsable chez les dirigeants de petites et moyennes entreprises
Authors: Da Fonseca Marie , Bonneveux Élise 
Published: October 2017

Cette recherche propose de s’interroger sur la relation entre la vision et la représentation du dirigeant de petite et moyenne entreprise (PME) et l’émergence d’une logique d’action responsable. En effet, les PME constituent le cœur du tissu économique français et sont de plus en plus sollicitées pour adopter des pratiques et stratégies responsables. Pour caractériser la vision, nous distinguons deux approches : l’une instrumentale et l’autre cognitive (Gond et Igalens, 2016). La représentation de la RSE est analysée selon trois aspects : la perception d’une dimension stratégique ou non, la projection à court ou à long terme, et la conception de la RSE, soit globale, soit opposant l’économique au social et à l’environnemental. Les logiques d’action responsable sont appréhendées dans la lignée des travaux de Rooke et Torbert (2005) puis de Boiral, Cayer et Baron (2009) et Boiral, Baron et Gunnlaugsin (2014) qui en ont proposé une typologie. L’étude des logiques d’action responsable dans six cas de PME nous a permis d’établir une typologie de trois profils de dirigeants et de les relier aux actions mises en œuvre.
Opérationnalisation du développement durable et action collective : étude d’un cas de promotion immobilière
Authors: Komi Abdoul Karim , Maillefert Muriel 
Published: October 2017

Au fil des années, de nouvelles normes ont été développées pour réguler le monde de la construction. Elles s’inscrivent dans une logique d’opérationnalisation du développement durable (DD) que nous cherchons à comprendre à travers l’analyse des représentations des parties prenantes d’une promotion immobilière privée et en nous appuyant sur une approche par l’action collective. Elle vise à comprendre la manière dont l’action se structure et se justifie. Dans un premier temps, nous proposons une caractérisation de cette action fondée sur l’intérêt qui la porte et permettant de différencier et d’expliciter les représentations. Au-delà de cette détermination structurante de l’action, d’autres variables sont mobilisées : la nature/taille du groupe, la dimension socio-spatiale, l’horizon temporel, le principe, le processus et le résultat de l’action. Une grille d’analyse est ainsi définie pour procéder à une étude de cas. Le matériau empirique est collecté par entretiens semi-directifs et analysé qualitativement et quantitativement à l’aide du logiciel Alceste. Trois univers d’action idéaux-typiques sont identifiés : une logique d’entreprise, une logique sectorielle et une logique territoriale. Ces univers se différencient de manière assez claire, et organisent des visions bien distinctes du DD et de son opérationnalisation dans le secteur de la promotion immobilière. Se pose alors la question de la convergence des logiques d’action en vue d’opérationnaliser le développement durable à l’échelle d’un territoire. Les élus la voient comme partenariale et non-financière alors que les dirigeants du promoteur immobilier privé en ont une conception actionnariale et financière. Une des conditions de l’opérationnalisation semble ainsi résider dans la construction d’un compromis autour de la valeur associée au DD.
Petrophysical Characterization of Carbonates Heterogeneity
Authors: Pires L. O. , Fiorelli G. L. , Winter A. , Trevisan O. V. 
Published: October 2017

The heterogeneity of carbonate rocks results from their origin and their sensitivity to physical, chemical and biological alterations, such as dissolution, cementation and recrystallization of their minerals. These phenomena lead to pores with different shapes, origins and sizes, and, consequently, makes it difficult to predict the porosity and permeability distributions of these rocks. In addition, the high heterogeneity of carbonates affects the flow of fluids inside the reservoir and, therefore, the final oil recovery, evidencing the importance of an exhaustive petrophysical characterization of these rocks.
In the present paper carbonate rocks from the same formation were investigated, grouped into two sets: Low Permeability set (LP), with a permeability range between 5 and 15 mD; and High Permeability set (HP), with a permeability range between 90 and 150 mD. Besides basic petrophysical properties (porosity and permeability), other properties, such as pore size and pore throat size distributions, surface area, capillary pressure and relative permeability curves of each set were studied in order to correlate their properties with rock heterogeneity.
Nuclear Magnetic Resonance (NMR) was used to evaluate pore size distributions and the Mercury Intrusion Porosimetry (MICP) was used to determinate pore throat size distributions and capillary pressure curves. It was observed that HP set presents predominantly macropores and macro-throats (about 90% of the porous structure), whereas the LP set presents about 80% of macropores, but approximately the same distribution of mesoand macrothroats (from 40 to 50 %). The lack of macro-throats strangles fluids flow, and it may be one of the factors responsible for lower permeability of LP set samples. Furthermore, when the pore size and pore throat size distributions are similar, it is possible to convert the T2 distribution data to pore throat size with an acceptable correlation. Capillary pressure curves obtained by MICP were normalized with saturation data obtained by High Speed Centrifuge (HSC) tests. Initial water saturation was higher in LP set, as expected. Capillary pressure curves were compared with the data obtained by the two methods, presenting very comparable results. In the same way, the relative permeability curves also presented similar results by the two methods.
In this study we could observe the association that different permeabilities of rocks from the same formation have with petrophysical properties, such as pore size and pore throats distributions, capillary pressure and relative permeability curves.

Published: October 2017

Abstract
Chemokines and chemokine receptors have rapidly diversified in teleost fish but their immune functions remain unclear. We report in this study that CCL19, a chemokine known to control lymphocyte migration and compartmentalization of lymphoid tissues in mammals, diversified in salmonids leading to the presence of six CCL19-like genes named CK10a, CK10b, CK12a, CK12b, CK13a, and CK13b. Salmonid CCL19-like genes all contain the DCCL-conserved motif but share low amino acid sequence identity. CK12 (but not CK10 or CK13) is constitutively expressed at high levels in all four trout MALT. Nasal vaccination with a live attenuated virus results in sustained upregulation of CK12 (but not CK10 or CK13) expression in trout nasopharynx-associated lymphoid tissue. Recombinant His-tagged trout CK12a (rCK12a) is not chemotactic in vitro but it increases the width of the nasal lamina propria when delivered intranasally. rCK12a delivered intranasally or i.p. stimulates the expression of CD8α, granulysin, and IFN-γ in mucosal and systemic compartments and increases nasal CD8α+ cell numbers. rCK12a is able to stimulate proliferation of head kidney leukocytes from Ag-experienced trout but not naive controls, yet it does not confer protection against viral challenge. These results show that local nasal production of CK12a contributes to antiviral immune protection both locally and systemically via stimulation of CD8 cellular immune responses and highlight a conserved role for CK12 in the orchestration of mucosal and systemic immune responses against viral pathogens in vertebrates.
The role of church youth in the transformation agenda of South African cities
Authors: Baron Eugene 
Published: October 2017

The churches in City of Tshwane have incredible youth capital. There is so much energy and passion that fill the concrete walls of the mushrooming churches. This article emerges from a research that was conducted to explore religious innovation and competition amidst demographic and social change among churches in the City of Tshwane. The data of the study suggest that the impetus behind most of the innovation and development in the churches is borne from the hearts and minds of the young people. The striking involvement of the youth in the congregations, their participation and also the reflection in the data in terms of youth agency highlight the concern on their involvement in urban, social change, with specific reference to the City of Tshwane. The article assesses the participation of the church youth in the transformation of the city.

Published: October 2017

ABSTRACT

Background
Video recording of resuscitation from fixed camera locations has been used to assess adherence to guidelines and provide feedback on performance. However, inpatient cardiac arrests often happen in unpredictable locations and crowded rooms, making video recording of these events problematic.

Objective
We sought to understand the feasibility of Google Glass (GG) as a method for recording inpatient cardiac arrests and capturing salient resuscitation factors for post-event review.

Methods
This observational study involved recording simulated cardiac arrest events on inpatient medical wards. Each simulation was reviewed by 3 methods: in-room physician direct observation, stationary video camera (SVC), and GG. Nurse and physician specialists analyzed the videos for global visibility and audibility, as well as recording quality of predefined resuscitation events and behaviors. Resident code leaders were surveyed regarding attitudes toward GG use in the clinical emergency setting.

Results
Of 11 simulated cardiac arrest events, 9 were successfully recorded by all observation methods (1 GG failure, 1 SVC failure). GG was judged slightly better than SVC recording for average global visualization (3.95 versus 3.15, P = .0003) and average global audibility (4.77 versus 4.42, P = .002). Of the GG videos, 19% had limitations in overall interpretability compared with 35% of SVC recordings (P = .039). All 10 survey respondents agreed that GG was easy to use; however, 2 found it distracting and 3 were uncomfortable with future use during actual resuscitations.

Conclusions
GG is a feasible and acceptable method for capturing simulated resuscitation events in the inpatient setting.

A la búsqueda de la libertad. La pedagogía universitaria de nuestro tiempo
Authors: Nóvoa Antonio , Amante Lúcia 
Published: October 2017

El texto presentado se centra en la pedagogía universitaria en tanto que dimensión central de una reflexión más amplia sobre las epistemologías docentes. Se presenta una propuesta de análisis general sobre los cambios en las universidades cuestionando la pedagogía y su incapacidad para acomodarse a las transformaciones recientes de la sociedad y de la propia universidad. Se apuntan las tendencias que tienden a dominar las “ideologías de la modernización” de las universidades, remarcando los obstáculos que tales ideologías contienen de cara al desarrollo profesional de los profesores. Se defiende una propuesta de renovación pedagógica –el ARCO de la Pedagogía universitaria– centrada en cuatro ideas clave: Autonomía, Reflexión, Creación y Obligación. Concluye el texto, insistiendo en la necesidad de poner a los profesores y la Pedagogía en el centro del debate, subrayando la importancia de la libertad académica en el ejercicio de la profesión docente.
Fractal scaling analysis of groundwater dynamics in confined aquifers
Authors: Tu Tongbi , Ercan Ali , Kavvas M. Levent 
Published: October 2017

Abstract. Groundwater closely interacts with surface water and even climate systems in most hydroclimatic settings. Fractal scaling analysis of groundwater dynamics is of significance in modeling hydrological processes by considering potential temporal long-range dependence and scaling crossovers in the groundwater level fluctuations. In this study, it is demonstrated that the groundwater level fluctuations in confined aquifer wells with long observations exhibit site-specific fractal scaling behavior. Detrended fluctuation analysis (DFA) was utilized to quantify the monofractality, and multifractal detrended fluctuation analysis (MF-DFA) and multiscale multifractal analysis (MMA) were employed to examine the multifractal behavior. The DFA results indicated that fractals exist in groundwater level time series, and it was shown that the estimated Hurst exponent is closely dependent on the length and specific time interval of the time series. The MF-DFA and MMA analyses showed that different levels of multifractality exist, which may be partially due to a broad probability density distribution with infinite moments. Furthermore, it is demonstrated that the underlying distribution of groundwater level fluctuations exhibits either non-Gaussian characteristics, which may be fitted by the Lévy stable distribution, or Gaussian characteristics depending on the site characteristics. However, fractional Brownian motion (fBm), which has been identified as an appropriate model to characterize groundwater level fluctuation, is Gaussian with finite moments. Therefore, fBm may be inadequate for the description of physical processes with infinite moments, such as the groundwater level fluctuations in this study. It is concluded that there is a need for generalized governing equations of groundwater flow processes that can model both the long-memory behavior and the Brownian finite-memory behavior.

Authors: Petersen Guðrún Nína 
Published: October 2017

Abstract. The Icelandic Meteorological Office (IMO) conducted meteorological buoy measurements in the central Iceland Sea in the time period 2007–2009, specifically in the northern Dreki area on the southern segment of the Jan Mayen Ridge. Due to difficulties in deployment and operations, in situ measurements in this region are sparse. Here the buoy, deployment and measurements are described with the aim of giving a future user of the data set information that is as comprehensive as possible. The data set has been quality-checked, suspect data removed and the data set made publicly available from PANGAEA Data Publisher (https://doi.org/10.1594/PANGAEA.876206).

Com o objetivo de avaliar o poder da eficiência térmica de resíduos agrícolas e de serraria na produção de briquetes (lenha ecológica), avaliou-se o poder de combustão, densidade, umidade e minerais totais de briquetes de casca de arroz, caroço de açaí, acrescidos de pó de serra e breu amarelo. Pode-se observar que os briquetes acrescidos de resina breu amarelo apresentaram uma melhor queima e textura, pelo poder de aglutinação que a resina proporcionou bem como maior queima, não houve diferença do potencial energético entre umidade, materiais voláteis e densidade. No teste de combustão, o tratamento com casca de arroz foi superior aos demais

Esta pesquisa objetivou avaliar o uso de diferentes resíduos orgânicos provindos de restaurante universitário (RU), no processo de biodigestão anaeróbia. O experimento foi conduzido no Centro de Ciências Agrárias (CCA) da Universidade Federal de Santa Catarina (UFSC), nos meses de junho e julho de 2015, totalizando 43 dias. Considerou-se um delineamento experimental inteiramente casualizado, com 4 tratamentos (T1: arroz, T2: beterraba + alface, T3: feijão e T4: arroz+beterraba+alface+feijão) e 3 repetições. Todos os tratamentos receberam 500g de resíduo in natura, de acordo com seu teor de umidade, 1000g de água e 150g de inóculo de esterco bovino. Monitorou-se, antes, durante e depois do processo de fermentação as temperaturas internas dos biodigestores, temperatura interna e externa da caixa, onde os biodigestores ficaram contidos e a produção de biogás. Analisou-se o pH, os teores de carbono orgânico e nitrogênio total dos resíduos e a massa do biofertilizante. Observou-se que o tratamento T1 iniciou a produção de biogás a partir do sétimo dia, o tratamento T3 teve maior produção de biogás, enquanto os tratamentos T2 e T4 não produziram biogás. O tratamento T1 apresentou maior redução do teor de carbono orgânico e maior acréscimo do teor de nitrogênio total. Concluiu-se que as condições de temperatura dos biodigestores e os tipos de resíduos orgânicos afetam o desempenho da biodigestão anaeróbia, o arroz e feijão são potenciais resíduos orgânicos para produção de biogás e biofertilizante.

Published: October 2017

O presente trabalho tem como objetivos propor uma metodologia numérica para predizer o comportamento de escoamentos turbulentos em ambientes conectados a uma chaminé solar e avaliar a influência da geometria da chaminé sobre o desempenho do escoamento no ambiente através do método Design Construtal. O sistema consiste em um escoamento bidimensional, incompressível, turbulento e com transferência de calor por convecção natural em um ambiente representado por uma região retangular conectado a uma chaminé solar com parede passiva inclinada (apenas transmite o fluxo radiante incidente). A simulações foram realizadas com Rayleigh RaH = 1,36 × 1014 e número de Prandtl de aproximadamente Pr = 0,7. No estudo de avaliação geométrica busca-se obter a melhor vazão mássica de ar no domínio computacional. O sistema é submetido a duas restrições, dadas pela área da chaminé e a área do ambiente construído. A geometria da chaminé (que foi avaliada no presente trabalho) é submetida a dois graus de liberdade: We/Wg e We/Ht. Sendo We a base superior da chaminé, saída, Wg base inferior da chaminé e Ht sua altura total. Para todos os casos foi considerada uma relação We/Ht = 0,1. As equações temporais médias de conservação de massa, quantidade de movimento e energia são resolvidas através do método dos volumes finitos (MFV). Para fechamento das equações médias no tempo é empregado o modelo a duas equações k – ε. A vazão mássica obtida com o presente modelo foi concordante dentro de 92,3% com os resultados propostos na literatura, inclusive para o fator adimensional avaliado na literatura estando dentro de 99,7% de concordância, para um caso específico (cuja inclinação da parede passiva foi de 4º). Com relação a avaliação geométrica, foi observado que para a faixa de geometrias estudadas (0.1 ≤ We/Wg ≤ 1.0) a vazão mássica máxima foi obtida no extremo superior, ou seja, (We/Wg)o = 1.0. Além disso, foi observada uma diferença na vazão mássica de 71,6 % entre a geometria ótima e a pior geometria, mostrando a aplicabilidade do Design Construtal neste problema. Palavras chave: chaminé solar, ventilação, vazão mássica, avaliação geométrica, Design Construtal.
