Existe-t-il un modèle feminin de management ? Analyse exploratoire des discours et vécus des femmes chefs d’entreprise au Sénégal.
Authors: Mendy Melyan
Published: August 2017

Les femmes chefs d’entreprise évoluant dans le monde des affaires sénégalais contribuent largement au développement économique et social en tant que pourvoyeuses d’emplois et gestionnaires d’entreprises créatrices de valeurs. Même si la plupart des entreprises qu’elles dirigent relèvent du secteur informel, nombreuses sont les femmes qui sont aujourd’hui à la tête d’entreprises modernes sous la forme des sociétés à capitaux (SARL ou SA) exerçant dans les trois principaux secteurs d’activités économiques (primaire, secondaire et tertiaire). Ces femmes arrivent à concilier leurs responsabilités domestiques, familiales et professionnelles (en tant que femme, épouse, mère et chef d’entreprise) pour diriger des entreprises performantes dans un environnement très concurrentiel. Ainsi est-on amené à se demander si elles avaient développé un modèle de management des entreprises, qui leur est propre. Les résultats de l’enquête exploratoire menée auprès des premières concernées montrent un nombre important de pratiques managériales propres aux femmes chefs d’entreprise qui portent les prémices d’un modèle féminin de management au Sénégal.

Authors: Kamwa Eric , Valognes Fabrice
Published: August 2017

Pour une situation de vote, le paradoxe fort de Borda se produit lorsqu’il existe un perdant de Condorcet et que ce dernier est élu. Un perdant de Condorcet est un candidat battu dans chacun de ses duels majoritaires. Pour des situations de vote avec trois candidats, nous utilisons une approche analytique pour déterminer l’ensemble de toutes les règles de scores vulnérables au paradoxe fort de Borda ceci sous certaines restrictions préférences ; aussi, nous décrivons tous les scénarios concernant le rang du perdant de Condorcet dans le classement collectif. A partir de l’algorithme paramétré de Barvinok et sous l’hypothèse de culture neutre et anonyme, nous proposons pour chaque type de restriction des préférences, une représentation simplifiée des probabilités du paradoxe fort de Borda pour les règles de la Pluralité simple et de l’Antipluralité.
Un diplomate face à la guerre civile espagnole : l’ambassade d’Eirik Labonne (octobre 1937 - octobre 1938)
Authors: Rousselot Nathan
Published: August 2017

Lorsqu’il est nommé à la tête de l’ambassade de France en Espagne le 2 octobre 1937, Eirik Labonne fait face à une situation exceptionnelle. Il doit réorganiser un poste diplomatique éclaté de part et d’autre de la ligne de front qui divise le pays et marginalisé par la gestion de son prédécesseur, Jean Herbette, qui séjournait en France, à Saint-Jean de Luz, loin du gouvernement républicain auprès duquel il était accrédité. Cet héritage est la source de nombreuses tensions franco-espagnoles que Labonne doit apaiser, avec un certain succès. Mais sa mission reste pour l’essentiel, conformément à la politique de non-intervention, la recherche d’une médiation internationale visant à mettre fin au conflit, au risque de compromettre les capacités de résistance de la République espagnole.
La « Wilton Park Connection » : un instrument de la diplomatie culturelle suisse pour l’après-guerre
Authors: Van Dongen Luc
Published: August 2017

Après avoir servi de source d’information aux services de renseignements britanniques pendant la guerre, le camp de prisonniers allemands de Wilton Park devint dès 1946 un haut lieu de sociabilité internationale d’un genre nouveau. Sous une forme qui mettait en avant la liberté de penser et la sincérité des contacts humains, loin de toute propagande, l’institution entreprit d’abord de « rééduquer » les prisonniers de guerre allemands et de réfléchir aux relations anglo-allemandes. Puis elle accueillit des Européens à propos de la question européenne, et enfin des personnalités du monde entier pour aborder tous les sujets brûlants de l’actualité. Chacune de ces phases vit une participation considérable – voire même décisive – de Suisses, car la Confédération fit, elle aussi, de ce centre semi-officiel, financé par le Foreign Office mais relativement indépendant, un instrument de sa diplomatie culturelle naissante.
Géopolitique du passage du Nord-Ouest. Une perspective de relations internationales
Authors: Lasserre Frédéric
Published: August 2017

La question du statut des eaux du passage du Nord-ouest pose fondamentalement la question de l’inclusion ou non de ce détroit maritime dans l’espace maritime souverain du Canada. Symétrique de la question du passage du Nord-est pour la Russie, elle oppose une interprétation du statut du passage comme détroit international ouvert au transit de tout navire selon les normes du « passage innocent », à l’inclusion de ce détroit dans des eaux intérieures, donc soumis à la pleine et entière souveraineté de ce pays. Avec les changements climatiques s’est développé un discours médiatique et scientifique abondant sur l’intérêt stratégique potentiel du passage du Nord-ouest : l’ouverture de celui-ci bouleverserait, selon plusieurs chercheurs, les stratégies des États par rapport à l’Arctique en dégageant des routes maritimes nettement plus courtes. Or, il s’avère que les relations entre États demeurent cordiales sur le sujet, malgré l’existence de désaccords. La question du passage du Nord-ouest n’a pas entraîné l’émergence d’un litige fort entre le Canada et d’autres pays au sujet de la souveraineté sur cette route arctique.
Evidence based selection of probiotic strains to promote astronaut health or alleviate symptoms of illness on long duration spaceflight missions
Authors: Douglas G.L. , Voorhies A.A.
Published: August 2017

Spaceflight impacts multiple aspects of human physiology, which will require non-invasive countermeasures as mission length and distance from Earth increases and the capability for external medical intervention decreases. Studies on Earth have shown that probiotics have the potential to improve some of the conditions that have manifested during spaceflight, such as gastrointestinal distress, dermatitis, and respiratory infections. The constraints and risks of spaceflight make it imperative that probiotics are carefully selected based on their strain-specific benefits, doses, delivery mechanisms, and relevance to likely crew conditions prior to evaluation in astronauts. This review focuses on probiotics that have been incorporated into healthy human gastrointestinal microbiomes and associated clinically with improvements in inflammatory state or alleviation of symptoms of crew-relevant illness. These studies provide an evidence base for probiotic selection with the greatest potential to support crew health and well-being in spaceflight.

Optimization of Clustering in Wireless Sensor Networks Using Genetic Algorithm
Authors: Parwekar Pritee , Rodda Sireesha
Published: August 2017

The energy of a sensor node is a major factor for life of a network in wireless sensor network. The depletion of the sensor energy is dependent on the communication range from the sink. Clustering is mainly used to prolong the life of a network with energy consumption. This paper proposes optimization of clustering using genetic algorithm which will help to minimize the communication distance. The cluster overhead and the active and sleep mode of a sensor is also considered while calculating the fitness function to form the cluster. This approach helps to prolong the network life of sensor network. The proposed work is tested for different number of nodes and is helping to find the correct solution for the selection of cluster heads.
The Risk of Optimization in Marketing Campaigns
Authors: Paetz Jürgen
Published: August 2017

In marketing one of the most common important tasks is to assign campaigns to sets of customers. These sets of customers, the target groups, consist of persons with similar properties, for example a high buying affinity for a certain product. Database marketers would not only assign a campaign by general economic or promotional consideration, but they take into account learning from databases by algorithms. The basic assumptions are already determined clusters to which campaigns, representing the products, should be assigned. The assignment can be done in the most optimal way by formal optimization, which is usually stochastic due to unknown campaign success in the future. The authors model the financial risk of the campaign success for enterprise practice. Their proposal is to use triangular distributions, known from financial and supply chain management applications. In an example, they demonstrate the benefits of the proposed procedure for the marketing task.
Offshore Software Testing in the Automotive Industry
Authors: Rentería y Hernández Tabata Pérez , Marsden Nicola
Published: August 2017

This paper presents a mixed-method study performed in the software department of an automotive supplier operating in India as an offshore service provider to a German company. The research focuses on the social dimension and human aspects involved in software testing in an intercultural setting. Qualitative and quantitative analyses of testers' perception regarding their daily activities and challenges were conducted. External and internal factors posing recurrent problems for testers were identified. Among the external were late inputs (documentation and software) and lack of recognition on the contribution of testing by other teams. A key internal factor was the view testers themselves hold about testing: boring when describing manual tests and interesting for the automated ones. Some of the testers feel they are not recognized by other teams and are not entirely satisfied with their job. Maintaining motivation over time was found to be a fundamental problem for testers.
Towards Proxemic Mobile Collocated Interactions
Authors: Lucero Andrés , Serrano Marcos
Published: August 2017

Research on mobile collocated interactions has been exploring situations where collocated users engage in collaborative activities using their personal mobile devices (e.g., smartphones and tablets), thus going from personal/individual toward shared/multiuser experiences and interactions. The proliferation of ever-smaller computers that can be worn on our wrists (e.g., Apple Watch) and other parts of the body (e.g., Google Glass), have expanded the possibilities and increased the complexity of interaction in what we term “mobile collocated” situations. Research on F-formations (or facing formations) has been conducted in traditional settings (e.g., home, office, parties) where the context and the presence of physical elements (e.g., furniture) can strongly influence the way people socially interact with each other. While we may be aware of how people arrange themselves spatially and interact with each other at a dinner table, in a classroom, or at a waiting room in a hospital, there are other less-structured, dynamic, and larger-scale spaces that present different types of challenges and opportunities for technology to enrich how people experience these (semi-) public spaces. In this article, the authors explore proxemic mobile collocated interactions by looking at F-formations in the wild. They discuss recent efforts to observe how people socially interact in dynamic, unstructured, non-traditional settings. The authors also report the results of exploratory F-formation observations conducted in the wild (i.e., tourist attraction).
Machine Learning Classification to Effort Estimation for Embedded Software Development Projects
Authors: Iwata Kazunori , Nakashima Toyoshiro , Anan Yoshiyuki , Ishii Naohiro
Published: August 2017

This paper discusses the effect of classification in estimating the amount of effort (in man-days) associated with code development. Estimating the effort requirements for new software projects is especially important. As outliers are harmful to the estimation, they are excluded from many estimation models. However, such outliers can be identified in practice once the projects are completed, and so they should not be excluded during the creation of models and when estimating the required effort. This paper presents classifications for embedded software development projects using an artificial neural network (ANN) and a support vector machine. After defining the classifications, effort estimation models are created for each class using linear regression, an ANN, and a form of support vector regression. Evaluation experiments are carried out to compare the estimation accuracy of the model both with and without the classifications using 10-fold cross-validation. In addition, the Games-Howell test with one-way analysis of variance is performed to consider statistically significant evidence.
Designing Stories for Educational Video Games
Authors: López-Arcos J.R. , Padilla-Zea N. , Paderewski P. , Gutiérrez F.L.
Published: August 2017

The use of video games as an educational tool initially causes a higher degree of motivation in students. However, the inclusion of educational activities throughout the game can cause this initial interest to be lost. A good way to maintain motivation is to use a good story that is used as guiding thread with which to contextualize the other video game elements (characters, scenarios, challenges, scores, etc.). A method is necessary for analyzing the effectiveness of the story in a video game. The authors propose an analysis method that includes user-centered techniques. This method has been applied to several cases of study. In this paper, they describe its application to the design of an educational video game in the field of mathematics and an adventure game for training the reading skills.
Enhancement Process of Didactic Strategies in a Degree Course for Pre-Service Teachers
Authors: Garcias Adolfina Pérez , Marín Victoria I.
Published: August 2017

This paper presents a study on the enhancement of didactic strategies based on the idea of personal learning environments (PLE). It was conducted through three iterative cycles during three consecutive academic years according to the phases of design-based research applied to teaching in a university course for pre-service teachers in the University of the Balearic Islands (Spain). Four teachers, one researcher and over 600 students took part in the study. The results show that both teachers and students were satisfied with the didactic strategy based on PLE management (Personal Learning Environment). There were also resulting signs showing that the students transferred what they had learnt to other contexts, and the strategy designed by the lecturers showed continuity. All this leads to the conclusion that the foundations have been set for a change in methodology.

Published: August 2017

The current work involves the measurement of thermo physical properties of commercial available blue dyed Kerosene, examining their behavior with alumina nano particles. It was found that the particle size of alumina ranged from 32 nm – 50 nm from the scanning electron microscope (SEM) analysis. Low volume concentrations (0.01%, 0.05% and 0.10% by volume) were used for this study. The parameters studied were thermal conductivity, viscosity and surface tension. The study was conducted at different range of temperatures (25-60 °C). Oleic acid was added as surfactant and the nanofluid was found to be stable for more than a week. The conductivity of the blue dyed kerosene alumina nanofluid increased with an increase in temperature and volume concentration. An enhancement of 9.33 % in conductivity was observed with a temperature of 60 °C for a volume concentration of 0.10%. The viscosity of the blue dyed kerosene decreased with increase in temperature. An average enhancement of 20% in viscosity of blue dyed kerosene alumina nanoparticles has been noted for a volume concentration of 0.10% as compared to the base kerosene. The surface tension of the kerosene alumina nanofluid decreased with an increase in temperature and decrease in concentration. An enhancement of 7.9 % in surface tension has been noted for volume concentration of 0.1% as compared to base kerosene at same temperature. The effect of temperature on thermo physical properties was determined by a linear decrease in surface tension as the temperature was raised. The results provide a strong proof that the addition of nano particles intensified the thermo physical properties to a considerable rate.

Published: August 2017

Optically active, tin mono-sulphide (SnS) nanoparticles, having generic name herzenbergite, being one of the narrow band gap IV–VI semiconductors, geared up recently the attention of material scientists for its applications in photovoltaics, near-infrared detectors, and biomedical applications where strong scientific information on infrared absorption is required. Among the class of chalcopyrite semiconductors, SnS is a relatively inexpensive and non-toxic material with the nature of resource abundance for solar cell applications, having a bulk direct band gap of 1.3 eV and indirect bandgap of 1.1 eV, possessing high figure of merit such as optimum optical band gap, high optical absorption coefficient for photons and high photoelectric conversion efficiency of up to 25%. In the present work, nanostructured SnS particles of 11.75 nm were synthesized by means of a cinch hydrothermal reaction using the reagents tin chloride pentahydrate and thiourea at 200°C. The crystallinity, purity, morphology, and structural featuresof as-prepared nanoparticles were characterized by Powder X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), UV-visible spectroscopy (Uv-vis), Photoluminescence spectroscopy (PL) and Fourier Transform Infra-red Spectroscopy (FTIR). XRD measurements reveal the formation of well-crystallized orthorhombic tin mono-sulphide nanoparticles which may be considered as a distorted NaCl structure. TEM observations demonstrate the morphology of the nanoparticles. The FTIR examination confirmed the existence of the vital functional groups. Absorption spectrum showed that the nanoparticles have an extensive absorption array. The optical properties determined by Uv-vis and PL measurements show that the prepared SnS nanoparticles will be an ideal candidate for photovoltaic applications.
Oxygen Requirements for Acutely and Critically Ill Patients
Authors: Siela Debra , Kidd Michelle
Published: August 2017

Oxygen administration is often assumed to be required for all patients who are acutely or critically ill. However, in many situations, this assumption is not based on evidence. Injured body tissues and cells throughout the body respond both beneficially and adversely to delivery of supplemental oxygen. Available evidence indicates that oxygen administration is not warranted for patients who are not hypoxemic, and hyperoxia may contribute to increased tissue damage and mortality. Nurses must be aware of implications related to oxygen administration for all types of acutely and critically ill patients. These implications include having knowledge of oxygenation processes and pathophysiology; assessing global, tissue, and organ oxygenation status; avoiding either hypoxia or hyperoxia; and creating partnerships with respiratory therapists. Nurses can contribute to patients’ oxygen status well-being by being proficient in determining each patient’s specific oxygen needs and appropriate oxygen administration.

Published: August 2017

BACKGROUND

Staff nurses are pivotal in leading change related to quality improvement efforts, although many lack skills to steer change from the bedside. The American Association of Critical-Care Nurses (AACN) staff nurse leadership program, Clinical Scene Investigator (CSI) Academy, teaches and empowers staff nurses in leadership skills and change concepts to translate evidence into practice affecting patient outcomes.

OBJECTIVES

To describe the curriculum of the AACN CSI Academy that provides staff nurses with the leadership skills required to create unit-based change projects that positively impact patient/family outcomes.

METHODS

The curriculum of the Academy included leadership topics, communication, change concepts, quality improvement methods, project management, and data management and analysis. Each team of participants collected project data to show improvements in patient care. The program evaluation used many data sources to assess the program effectiveness, relating to the professional growth of the participant nurses. The participants assessed project patient outcomes, sustainability, and spread.

RESULTS

The first cohort of CSI participants included 164 direct care nurses from 42 hospitals in 6 cities. They rated the Academy highly in the program evaluation, and they reported that the Academy contributed to their professional development. The individual hospital quality improvement projects resulted in positive patient and estimated fiscal outcomes that were generally sustained 1 year after the program.

CONCLUSION

With the skills, tools, and support obtained from participation in the CSI Academy, staff nurses can make substantial contributions to their organizations in clinical and possibly fiscal outcomes.
Levamisole-Adulterated Cocaine Leading to Fatal Vasculitis: A Case Report
Authors: Hammond Belinda B. , Craven Jordan
Published: August 2017

Cocaine is often “cut” with various additives to increase the profitability of the drug. One of the most common additives on today’s market is levamisole, an anthelmintic medication used to destroy and expel parasitic worms in animals. The use of levamisole-contaminated cocaine can result in agranulocytosis and vasculitis (inflammation and constriction of small blood vessels). The resulting clotting and decrease in peripheral blood flow lead to cutaneous lesions, particularly on the ears, face, hands, and feet, and in severe cases can cause generalized tissue necrosis throughout the entire body. Treatment is generally supportive, and symptoms typically abate with complete cessation of cocaine use. However, symptoms may recur with subsequent cocaine use and, as this case illustrates, severe neutropenia and extensive vasculitis may lead to overwhelming sepsis and death.
Cutting Edge: NKG2D Signaling Enhances NK Cell Responses but Alone Is Insufficient To Drive Expansion during Mouse Cytomegalovirus Infection

Published: August 2017

NK cells play a critical role in host defense against viruses. In this study, we investigated the role of NKG2D in the expansion of NK cells after mouse CMV (MCMV) infection. Wild-type and NKG2D-deficient (Klrk1−/−) Ly49H+ NK cells proliferated robustly when infected with MCMV strains engineered to allow expression of NKG2D ligands, which enhanced the response of wild-type NK cells. Naive NK cells exclusively express NKG2D-L, which pairs only with DAP10, whereas NKG2D-S expressed by activated NK cells pairs with DAP10 and DAP12, similar to Ly49H. However, NKG2D alone was unable to drive robust expansion of Ly49H− NK cells when mice were infected with these MCMV strains, likely because NKG2D-S was only transiently expressed postinfection. These findings demonstrate that NKG2D augments Ly49H-dependent proliferation of NK cells; however, NKG2D signaling alone is inadequate for expansion of NK cells, likely due to only transient expression of the NKG2D–DAP12 complex.
La relación bilateral entre Chile y el Perú: La propuesta del fallo de la Corte Internacional de Justicia como punto de inflexión histórico y su posterior fracaso
Authors: Arenas Riveros Rocío , Rivas Pardo Pablo
Published: August 2017

Entre los meses de enero de 2008 y enero de 2014 se vivió entre el Perú y Chile un contencioso en la Corte Internacional de Justicia. Si bien el fallo no dio todo lo solicitado al Perú, este país sí logró la incorporación de un nuevo espacio marítimo en desmedro de Chile. En este lapso de seis años surgió la propuesta de que el fallo de la Corte fuera un punto de inflexión que cambiaría una relación que históricamente ha sido de confrontación e inconstancia integrista a una, más bien, de base estructural cooperativa. La hipótesis no se aprobó, puesto que ocurrido el fallo inmediatamente se levantó un nuevo conflicto, el denominado “triángulo terrestre”, que eliminó la propuesta del punto de inflexión. En virtud de lo anterior, este artículo explica por qué no se logró cumplir con el punto de inflexión, en razón del denominado triángulo terrestre. El análisis del rechazo del punto de inflexión incluye los principales eventos de esta relación bilateral, explicando así, por qué un triángulo de 3,7 hectáreas tuvo un valor cualitativo mayor que cambiar una relación bilateral caracterizada por su inconstancia.

Published: August 2017

Apixaban is an oral anticoagulant that directly inhibits Factor Xa and is indicated for the prophylaxis and treatment of deep venous thrombosis and stroke prevention in non-valvular atrial fibrillation. Rectus sheath hematoma is a rare, life-threatening complication of anticoagulant treatment. We describe a case of an elderly patient on apixaban for the treatment of deep venous thrombosis who developed severe abdominal pain during hospitalization. Computed tomography of the abdomen revealed left rectus sheath hematoma. Apixaban was discontinued and the patient was monitored for extension of the hematoma. After 2 days she was discharged home. Outpatient computed tomography 1 month later showed complete resolution of the rectus sheath hematoma. We recommend that clinicians become aware of the potential for rare and serious bleeding complications of anticoagulants and identify the need for early recognition and prompt management.

Reliability of Diagnostic Criteria for Neurocysticercosis for Patients with Ventricular Cystic Lesions or Granulomas: A systematic review
Authors: Bustos Javier A. , García Hector H. , Del Brutto Oscar H.
Published: August 2017

Intraventricular neurocysticercosis (NCC) is a severe form of NCC requiring prompt diagnosis and treatment. We aimed to assess the reliability of the most recent version of diagnostic criteria for this form of NCC. Two systematic literature reviews were performed; one included case reports of patients with intraventricular cysticercosis and the other included case reports of patients with intraventricular cystic lesions or granulomas caused by infections other than NCC. All assessed cases were categorized according to the last revision of the long-standing Del Brutto’s set of diagnostic criteria to determine its sensitivity, specificity, and predictive value for this form of NCC. The search disclosed 128 patients with intraventricular NCC and 41 with other infections. The set of diagnostic criteria classified as definitive NCC 93 cases with intraventricular NCC (sensitivity 72.7%, 95% CI, 63.9–79.9%), as well as four cases with other infections (specificity 90.2%, 95% CI, 75.9–96.8%). The positive and negative predictive values of the criteria were 0.96 (95% CI, 0.89–0.99) and 0.51 (95% CI, 0.39–0.63), respectively. The revised Del Brutto’s set of diagnostic criteria for NCC is acceptably sensitive and highly specific for diagnosing patients with the ventricular form of the disease.
Effect of Microalloying with Ti or Cr on the Corrosion Behavior of Al-Ni-Y Amorphous Alloys
Authors: Zhang L.M. , Ma A.L. , Hu H.X. , Zheng Y.G. , Yang B.J. , Wang J.Q.
Published: August 2017

The effect of microalloying with Ti or Cr on the corrosion behavior of Al-Ni-Y amorphous alloys in 0.1 M NaCl solution was studied by potentiodynamic polarization, Mott-Schottky, and x-ray photoelectron spectroscopy techniques. Microalloying with Ti or Cr could greatly improve the corrosion resistance of Al-Ni-Y amorphous alloys. A high surface concentration of Ti or Cr in the passive films was detected, which should be responsible for the improved corrosion resistance compared to the control sample. The possible process of Ti or Cr involved in the passive films was proposed in terms of the point defect model and the vacancy diffusion mechanism. Furthermore, the effect of Ti was stronger than Cr because of the higher film resistance as well as the higher surface concentration. The different passivation abilities and atomic radiuses between Ti and Cr were presented to explain the better microalloying effect of Ti compared to Cr.

Authors: Roth Leonardo , Gonçalves Roberto Birch , Bertolazzi Marco Aurélio , Fachinelli Ana Cristina
Published: August 2017

Os documentos digitais se tornam cada vez mais presentes na rotina das Instituições de Ensino Superior (IES) ampliando a preocupação com a integridade dos dados, a garantia da identidade e a confidencialidade das partes envolvidas. A legislação obriga a IES a manter a guarda dos documentos dos alunos, avaliações, registros de notas e assiduidade por anos e até por guarda perpétua. Portanto, quando uma IES adota um modelo para a guarda, tratamento e validação dos documentos em meio eletrônico ou digital adota, também, novos processos de gestão da informação que podem afetar a cultura organizacional. O objetivo deste estudo foi identificar e analisar as interfaces entre a inovação na gestão eletrônica de documentos e a cultura organizacional relacionado a mudanças de processo na guarda eletrônica de documento realizando-se um estudo de caso numa IES comunitária. Os resultados indicam que, embora existam dificuldades de adaptações ao processo devido à cultura de uma IES, com o amadurecimento do processo o aprendizado amplia os benefícios do novo processo pela disseminação da inovação e seus reflexos em outras áreas. O estudo concluiu que o processo de digitalização além de trazer vantagens onde foi aplicado, estendeu os benefícios para outras áreas da IES.

http://dx.doi.org/10.5007/2175-7925.2009v22n4p95O presente estudo objetivou conhecer a riqueza da mirmecofauna associada à microbacia da Sanga Caramuru, no município de Chapecó, que representa um dos principais afluentes da barragem do Lajeado São José. As coletas ocorreram de junho de 2006 a maio de 2007. Realizaram-se coletas quinzenais, totalizando 21 coletas. Foram utilizadas armadilhas do tipo pit-fall. A análise dos dados foi realizada através do programa estatístico EstimateS (Colwell). Obtiveram-se 676 registros de espécies nas armadilhas. Foram identificadas 51 espécies distribuídas em 18 gêneros distribuídos em sete subfamílias. A riqueza estimada através do estimador Chao 2 foi de 61,6 espécies para a área de mata nativa, 42,3 espécies para a área de banhado e de 39,8 espécies para a área com eucalipto. O índice de diversidade de Shannon-Wiener obtido foi o mesmo (3,2) para os ambientes amostrados. A maior riqueza e diversidade estimadas para a área de mata nativa coincidem com a  maior riqueza também observada neste local. Embora os impactos da antropização sejam facilmente constatados na área estudada, os pequenos fragmentos de áreas com vegetação presentes neste local oferecem os recursos para a manutenção de uma significativa mirmecofauna.
Práticas educativas e culturais de estudantes e suas percepções sobre as tecnologias móveis na escola
Authors: Fantin Monica , Quartiero Elisa Maria
Published: August 2017

Inserido em uma pesquisa interinstitucional desenvolvida em diferentes contextos socioculturais sobre o Projeto Um Computador por Aluno (UCA), este artigo apresenta um recorte sobre o foco das práticas pedagógicas com objetivo de refletir sobre as práticas educativas e culturais de estudantes e suas percepções sobre o Projeto. Com abordagem teórico-metodológica fundamentada na pesquisa mídia-educativa, discute-se um estudo de caso múltiplo realizado em quatro escolas públicas e que envolveu observações do cotidiano escolar, pesquisa-formação, intervenção didática e grupos focais com estudantes de diferentes turmas do ensino fundamental. Para contextualizar a discussão, o texto inicia com um levantamento sobre diferentes pesquisas que tiveram o Projeto UCA como objeto e que foram desenvolvidas entre 2011 e 2014. Em seguida, apresenta-se a escolha metodológica da pesquisa e a discussão sobre as especificidades das práticas culturais e das percepções de estudantes a respeito do Projeto. Por fim, o artigo traz algumas considerações que demonstram que a riqueza e a diversidade das práticas presentes em um mesmo projeto também podem ser entendidas como uma polifonia de vozes de estudantes, professores e pesquisadores, como interpretações possíveis que configuram a referida pesquisa em um espaço de alteridade e de imersão na cultura digital.
Origem e evolução do paradigma da escola eficaz e seus desdobramentos no contexto atual
Authors: Silva Isabelle Fiorelli
Published: August 2017

Este artigo esboça uma evolução histórica das pesquisas em efetividade escolar, abarcando as noções de efeito-escola e escola eficaz, pois tais noções foram construídas historicamente e compõem a evolução e a adoção desse conceito a partir dos anos de 1980 quando se inicia a investida neoliberal nas reformas dos sistemas de ensino. Dessa forma, objetiva-se apresentar o processo de evolução, mutação e adaptação de tal paradigma a cada contexto político-econômico até sua última forma no contexto globalizado e neoliberal. Para tanto, utiliza-se exaustiva revisão bibliográfica tendo como categorias de análise a escola eficaz e o efeito-escola, os conceitos de eficácia, eficiência e efetividade, e a aplicação de tais conceitos na reforma da política educacional engendrada nos anos de 1980 e 1990. Conclui-se que o paradigma da escola eficaz evoluiu e no contexto atual se materializa nas “políticas de resultados”, “políticas de performance” ou “políticas de evidências” que deflagra uma visão estreita e mecânica dos processos educativos.
A pesquisa de Goethe com as cores e a educação fenomenológica
Authors: Bach Junior Jonas
Published: August 2017

Este artigo apresenta os fundamentos da Teoria das Cores de Goethe. As cores fisiológicas e físicas apresentam dois princípios: de complementaridade e intensificação. O método de pesquisa de Goethe é conhecido como fenomenológico. Em sua abordagem do fenômeno, não há uma redução às representações mecânicas e geométricas, e seu foco é a qualidade do fenômeno. O círculo cromático é composto através da pesquisa com as cores fisiológicas e físicas, o autor apresenta seis cores em vez de sete como no prisma de Newton. A observação fenomenológica do céu confirma os estudos do prisma. A fenomenologia de Goethe é um processo de educação dos sentidos e da qualidade da cognição.
“Super-Meninas em: o poder do rosa!?!” Por uma compreensão das feminilidades infantis a partir dos estudos de mídia, gênero e infância

O presente artigo problematiza o lugar social e cultural da menina, no contexto dacultura midiática globalizada. O recorte analítico remete à pesquisas realizadas comcrianças de séries iniciais, da região da grande Florianópolis, em seus contextos escolarese da presença de referenciais identitários que culminam na imagem da quedenominamos Menina-Super-Poder-Rosa. A análise dialoga, tensiona e questiona talrepresentação, cujos signi􀃫cados são marcados pela sua inerente ambiguidade econtradição, sobretudo quando apropriados e ressigini􀃫cados pelas crianças. Talimagem congrega elementos e caraterísticas que se voltam a uma espécie defeminilidade infantil contemporânea, onde é possível constatar matrizes culturais maistradicionais. Nesse sentido, 􀃫guram aspectos ligados à passividade e à subserviênciafeminina ao lado de características mais atuais relacionadas às conquistas feministas e aoempoderamento das mulheres. Para a realização da pesquisa com as crianças, fez-se usoda etnogra􀃫a e da pesquisa-intervenção com o propósito de problematizar as relações depoder, principalmente as voltadas às questões de gênero, infância e mídia. Comoresultado, notou-se que as feminilidades infantis por mais que tenham avançado rumoà igualdade de direitos e à liberdade de expressão, ainda continuam ocupando um lugarde subalternidade, de inferiorização e de naturalização das diferenças, sendocristalizadas em práticas sexistas e discriminátorias, as quais são vivenciadas ereproduzidas cotidiadianamente nas interrelações infantis.
Caracterização Morfológica e Hidrodinâmica de Praias do Estado de Santa Catarina com Vista à Avaliação de Perigo ao Banhista

O objetivo deste trabalho foi avaliar o grau de perigo aos banhistas de 14 praias do litoral de Santa Catarina. Para isso foi utilizada a metodologia aplicada nos planos de segurança nas praias australianos. O método consiste em calcular o grau de perigo com base no estágio morfodinâmico e na altura de quebra da praia. As praias a serem avaliadas foram escolhidas com base no número de ocorrências apontado no registro do corpo de bombeiros do estado. A classificação do estágio morfodinâmico das praias foi realizada com fotografia aérea e imagens de satélite. Os dados de altura de onda foram obtidos da base de dados do projeto SMC Brasil. Dentre as praias analisadas houve o predomínio do estágio intermediário com apenas uma praia refletiva e nenhuma praia dissipativa. Os graus de risco variaram de baixo a moderado nas praias verificadas.
Entre peixes e humanos: o conflito pesca e conservação ambiental no litoral sul do Brasil
Authors: Martins Andreza , Dias Leila Christina , Cazella Ademir Antonio
Published: August 2017

Em um cenário atual de mudanças climáticas, sobrepesca, esgotamento generalizado dos recursos pesqueiros marinhos associados ao aumento exponencial da demanda per capita mundial pelo consumo de peixes e derivados, a delimitação de espaços marinhos protegidos continua a ser adotada, em escala global, como a principal ferramenta política territorial para salvaguarda dos ambientes marinhos. Partindo da análise da rede de atores associados à pesca em uma área marinha protegida no litoral sul do Brasil, demonstramos que embora a criação de espaços protegidos seja fundamental para minimizar impactos humanos sobre ambientes marinhos e oceânicos, a iniciativa isolada não limita a pressão antrópica. Nesse sentido, evidenciamos que são as estratégias dos atores localizados em distintas escalas espaciais de atuação política que sustentam, de fato, a geração de acordos e parcerias passíveis de gerar melhorias para conservação marinha.
