Response decision, emotions, and victimization of police officers
Authors: van Reemst Lisa , Fischer Tamar FC , Zwirs Barbara WC
Published: June 2015

This study explores the question of whether response decision and situation-dependent emotions, concepts of the Social Information Processing model of Crick and Dodge (1994), are useful in explaining differences involving the victimization of police officers. Officers from five regional police forces in the Netherlands completed a digital questionnaire, based partially on the Social Information Processing Interview. Results indicated that victimization involving verbal violence, threats, and physical violence were associated with response decision but not with negative emotions. Police officers who had more negative outcome expectations of aggressive or assertive responses, or who selected an aggressive rather than a passive or assertive response, were more likely to report being a victim of violence than were other police officers. Not all results were as hypothesized, and associations were discussed in the context of police officers’ work situations, protocols, and training.

Published: June 2015

Liver X receptors are in the nuclear receptor superfamily and are contained in the regulation of lipid and cholesterol metabolism. Besides, liver X receptors are considered crucial regulators of the inflammatory response and innate immunity. The current study evaluates the in vivo effects that the synthetic liver X receptor agonist TO901317 protects against cisplatin-induced kidney injury in mice. Mice received cisplatin administration through a single intraperitoneal injection (20 mg/kg in saline). And then the mice were treated with the TO901317 by daily gavage (10 mg/kg/day) 12 h postcisplatin administration, and cisplatin nephrotoxicity was evaluated. At 72 h after cisplatin treatment, elevated plasma urea and creatinine levels ( P < 0.05) were evidenced which indicates the renal dysfunction of the vehicle-treated mice, consistent with tubular necrosis, protein cast, dilation of renal tubules, and desquamation of epithelial cells in renal tubules. In contrast, the severity of renal dysfunction and histological damage was reduced in TO901317 treated mice ( P < 0.05). In accordance, circulating tumor necrosis factor alpha levels, renal tumor necrosis factor alpha, p47phox, gp91phox, and protein expression levels and COX-2 mRNA, renal monocyte chemoattractant protein 1, VACAM-1 mRNA and intercellular adhesion molecule-1 contents, and renal prostaglandin E2 amounts, were higher in samples from cisplatin-treated mice in comparison with controls ( P < 0.05) but attenuated in the TO901317 treatment group ( P < 0.05). Taken together, treatment with the liver X receptor agonist TO901317 ameliorated the inflammatory response and oxidative stress in cisplatin-induced kidney injury in mice.
Ex vivo manipulation of bone marrow cells to rescue uremia-induced dysfunction for autologous therapy
Authors: Grange Cristina , Bussolati Benedetta
Published: June 2015

Uremic toxins are known to affect the regenerative properties of tissue-resident and circulating stem cells and thus appear to be a limiting factor for autologous stem cell-based approaches for treating chronic kidney disease. The recent article by van Koppen and colleagues in Stem Cell Research & Therapy provides evidence that an ex vivo short-term pre-treatment with statins reverts the dysfunction of bone marrow stem cells isolated from rats with renal impairment. Indeed, statin pre-treated cells improved renal function in a model of established chronic kidney disease. Our commentary discusses the potential of this approach in the context of autologous cell therapy and the available knowledge on the mechanisms involved in uremia-induced stem cell dysfunction.

Spójność, zgodność i dyscyplina ugrupowań parlamentarnych: przegląd aktualnych zagadnień badawczych
Authors: Sokołowski Jacek K.
Published: June 2015

Unity, cohesion and discipline of parliamentary groups: state of the art and the current research

The article sums up the development of a particular subdiscipline in parliamentary research, i.e. the cohesion analysis. By outlining approaches to parliamentary cohesion, it identifies the two major ones: the institutional one, focusing on intra– and extra parliamentary institutions influencing cohesion and the socio‑motivational one, focusing on individual MP’s motivations, shaped by more general or more individual factors (social norms, loyalty, individual preferences). The author assesses possible future developments of the field, noting that the insufficient theoretical framework hinders further progress in comparative studies. With regard to the very few Polish studies of the subject, the author proposes a clear Polish terminology relating to major concepts used to describe the voting behavior of a parliamentary group.
Klauzule rozłączności w konwencjach Rady Europy
Authors: Filipek Paweł
Published: June 2015

Under the auspices of the Council of Europe more than 200 international agreements were drafted and concluded. They foster closer cooperation primarily among member states and set Pan‑European legal standards. In some Council of Europe conventions special clauses have been introduced that allow a group of parties for a derogation from convention obligations – they are known as “disconnection clauses”. Disconnection clauses resemble conflict of law rules, are general in nature, normally are formulated in a unconditional way, and operate automatically. They are meant to provide protection for regulations established by more closely integrated states, e.g. Nordic states or the European Union. For the latter, they are crucial as they safeguard the EU autonomy and uphold primacy of EU rules vis‑à‑vis international obligations of member states. Yet disconnection clauses raise much concern as contributing to further fragmentation of international law and may possibly have a disadvantageous effect on compliance with and consistency of legal standards in Europe.

La rehabilitación integrada de los centros históricos: el reto urbanístico de finales de los ochenta
Authors: Campesino Fernández Antonio José
Published: June 2015

La quiebra del urbanismo positivista de los años sesenta y setenta precipita en los ochenta nuevos conceptos y prácticas de intervención en la ciudad. El urbanismo «recualificador» de la última generación en nuestros Centros Históricos se constituye en alternativa al ultraconservacionismo y a la renovación especulativa, evidenciando que la ciudad no es un instrumento de hacer dinero fácil y rápido, sino el marco de convivencia diaria sujeta a unas reglas claras de juego. No hay presente sin pasado y, por ello, la rehabilitación integrada pretende construir el patrimonio del futuro sobre el patrimonio heredado.
La climatología geográfica en Brasil: de lo producido a lo enseñado
Authors: Sant’anna Neto João Lima
Published: June 2015

Este artículo presenta una propuesta de Geografía del Clima, que se contrapone a la noción de una Climatología Geográfica. Por lo tanto, volviendo a los inicios de la Climatología en Brasil, se ha buscado establecer las bases conceptuales de la incorporación del fenómeno climático en la ciencia geográfica. Se discute la revolución paradigmática iniciada por Max Sorre y la propuesta de Figueiredo Monteiro, que parte de la aceptación de la noción de ritmo como nuevo paradigma para el análisis geográfico del clima. También se apunta la conveniencia de desarrollar una nueva adecuación de los conceptos de apropiación de la naturaleza por una sociedad estructurada en clases sociales. En última instancia se propone una discusión en la que se valora la necesidad de una nueva razón para un nuevo conocimiento del fenómeno climático en la perspectiva social de la valoración de los recursos naturales.

Pejotização e Parasubordinação
Authors: Silva Francizete Correia Amaro da , Santaguida Bárbara Maria Moreira Dante , Farias Athena De Albuquerque
Published: June 2015

O presente trabalho tem o intuito de abordar a pejotização e a parassubordinação, ligados ao ramo do Direito do Trabalho. Pois, é possível percebê-los inseridos contextualmente no Direito do trabalho, que vem a ser um conjunto de princípios e normas que regulam a relação entre empregados e empregadores. Seguindo essa lógica a parassubordinação vai além das fronteiras da subordinação, que até então é a sujeição ao poder de outra pessoa, enquanto que a pejotização seria a pessoa jurídica apresentando-se como se fosse uma pessoa física. Nesse contexto, surgem casos concretos e a problemática se estende pela sociedade civil e jurídica, fazendo com que haja a necessidade do ordenamento jurídico de forma mais homogênea e eficaz. Nesse âmbito, a temática em estudo torna-se relevante no que tange os aspectos formais e informais da lei, pois a priori, faz-se necessário uma boa caracterização das formas de trabalho conforme a lei trabalhista vigente bem como uma analise e o enquadramento dos conceitos de pejotização e parassubordinação.

Published: June 2015

The ongoing Ebola virus outbreak in several countries in West Africa was considered by the World Health Organisation (WHO) as a public health emergency of international concern. Healthcare providers must be prepared by organising specific procedures in our hospitals based on recommendations from national and international healthcare organisations. Two aims should be considered: appropriate medical care for patients with suspected or confirmed disease must be ensured, as must measures to prevent transmission to healthcare workers. The clinical laboratory plays an important role and must define and establish its own procedures in accordance with clinicians and integrated into those of the institution, starting with the definition of the organisation model in the laboratory to achieve those goals. In this review we present our experience based on the care of three patients with confirmed cases. We hope it will help other colleagues to plan for Ebola.

On the Fast Chemical Separation of Carrier-free Samples from Macro-amounts of Proton-irradiated Rare-Earth Targets
Authors: Oelsner-Ryde G. K.
Published: June 2015

The formation of precipitates, which appeared in the body of the cation-exchange resin beds during the chemical separation of carrier-free samples from proton-irradiated cyclotron targets of more than 50 mg of rare-earth oxides, is investigated. The properties and character of this insoluble salt are discussed. A method for such a separation, which avoids the disturbing influence of a precipitate, is given. The sample produced is suitable for beta ray spectroscopy. The method described is applicable to fairly short-lived rare-earth isotopes, as the procedure can be carried out within 8 hours.

Published: June 2015

Grobkörnige anorganische Ionenaustauscher werden durch Mischfällung adsorptionsaktiver Komponenten mit einer inaktiven Matrix hergestellt. Die entstehenden Produkte lassen sich leicht aufarbeiten und geben in Austauschersäulen Füllungen mit kleinem Strömungswiderstand. Ihre Eigenschaften werden durch Adsorptionsversuche von 137Cs/Ba und 234Th (UX1) an Mischfällungen von Zirkonphosphat und Zirkonhypophosphat mit Kieselsäure demonstriert. Da in saurer Lösung durch die Kieselsäure die Eigenschaften der adsorptionsaktiven Komponenten nicht wesentlich beeinflußt werden, sind solche Mischfällungen zum Studium der Grundeigenschaften neuer anorganischer Ionenaustauscher und für Anwendungen in der Radiochemie sehr geeignet.
Preparation of 18F in a Nuclear Reactor
Authors: Bresesti M. , Del Turco A. M. , Ostidich A.
Published: June 2015

18F has been produced irradiating LiN03 in the Ispra 1 reactor, by 16O(t, n)18F reaction using tritons from 6Li(n, t)4He reaction. A simple method is proposed for the purification of 18F, based on the adsorption on anionic alumina in OH- form and elution with NaF solution. Also the adsorption of 18F on magnesium oxide has been experimented. Several other salts containing lithium and oxygen have been irradiated. Some remarks are reported on the dependence of the 18F production yields from the chemical composition of the irradiated compounds.
Observations on Spur Reactions in the Liquid Phase γ-Radiolysis
Authors: Schindler Ralph N.
Published: June 2015

Propane and butane formation is observed in the liquid phase γ-radiolysis of mixtures of methyl with ethyl halide; butane and ethane formation occurs when mixtures of methyl with n-propyl iodide are irradiated. The G-values for these products are not affected by ≦ 10-2 moles/1 DPPH. These observations and the dependence of G (recombination products) on the composition of the mixtures strongly suggest that these hydrocarbons are formed by diffusion-controlled recombination in spurs.
The Effect of γ-Pre-Irradiation on Recoil Phenomena in Crystals
Authors: Dimotakis Paul N.
Published: June 2015

The γ-pre-irradiation effect on the recombination of recoil cobalt atoms in some neutron irradiated crystalline cobaltic complexes was examined. The introduction of defects into the lattice by pre-irradiation seems to increase the initial retention and promotes the annealing phenomenon, though on the other hand radiolytic phenomena may also appear. Plots of isothermal annealing curves appear to indicate the existence of two or more parallel consecutive recombination-decomposition reactions. A kinetic interpretation of such mixed phenomena is also given. Complex kinetic phenomena also appear to be quite general in annealing processes for systems already studied by other authors. These systems, if examined in this light, may lead to a new interpretation as to the way in which recombination occurs during annealing.
Versuche zur Identifizierung der bei der 191Ir (n, γ) 192Ir-Kernreaktion entstandenen chemischen Folgeprodukte im Na2lrCl6 • 6H2O

Im System Na2IrCl6 · 6H2O konnten auf elektrophoretischem Wege zahlreiche individuelle Rückstoßverbindungen, die auf Grund des 191Ir (n, γ)
192Ir-Kernprozesses entstehen, getrennt werden. Diese haben vornehmlich anionischen Charakter, doch werden auch zwei 192Ir-markierte Kationen beobachtet. Es wurde das chemische Verhalten dieser mit wenigen Ausnahmen in trägerfreier Form vorliegenden Produkte während des Alterns in In HCl-Lösung und bei Reduktion des IrlV zum IrIII studiert. Zum Verständnis des Hydrolysevorganges der 36Cl und 192Ir markierten Hexachlorokomplexe des 3- und 4wertigen Iridiums erwies sich die gleichzeitige Anwendung von aktivierungsanalytischen Methoden als sehr nützlich. Diese Kenntnisse ermöglichten es, die Natur der im Pherogramm auftretenden 192Ir-Rückstoßverbindungen weitgehend zu klären. Der überwiegende Teil ist auf oktaedrische Komplexe des 3wertigen Iridiums mit wechselnden Anteilen an Cl-, H2O- und OH--Liganden zurückzuführen. Von Bedeutung ist die Mitwirkung der 6 Kristallwassermoleküle, welche über Ionen und Radikale die Kombinations- und Stabilisierungs- Reaktionen beeinflussen und so auch die Entstehung von bisher zum Teil noch unbekannten Iridium- Komplexverbindungen verständlich machen.
Determination by Neutron Activation of Gallium and Germanium in Iron Meteorites
Authors: Wasson John T. , Kimberlin Jerome
Published: June 2015

A procedure is given for the simultaneous determination by neutron activation of gallium and germanium in iron meteorites or other similar materials. Germanium is separated from interfering activities by solvent extraction from 8 Ν HCl into carbon tetrachloride followed by distillation as GeCl4. The chemical yield is determined colorimetrically using phenylfluorone. Gallium is separated by repeated solvent extactions into isopropyl ether, and the yield is determined by flame photometry. About 12 man hours are necessary to process six to eight samples, not including the time necessary to reduce the counting data. The detection limits for a thermal-neutron flux of 1012 cm-2 sec-1 are about 0.02 ppm germanium and 0.0001 ppm gallium.

Published: June 2015

Flexible copper indium gallium diselenide (CIGS) solar cells on lightweight substrates can deliver high specific powers. Flexible lightweight CIGS solar cells are also primary candidates for building-integrated panels. In all applications, CIGS cells can greatly benefit from the application of broadband and wide-angle AR coating technology. The AR coatings can significantly improve the transmittance of light over the entire CIGS absorption band spectrum. Increased short-circuit current has been observed after integrating AR coated films onto baseline solar panels. NREL’s System Advisor Model (SAM) has predicted up to 14% higher annual power output on AR integrated vertical or building-integrated panels. The combination of lightweight flexible substrates and advanced device designs employing nanostructured optical coatings together have the potential to achieve flexible CIGS modules with enhanced efficiencies and specific power.

Published: June 2015

No estado do Tocantins, o cultivo de milho em "terras altas sob cerrado" apresenta níveis de produtividade variáveis, cuja média não ultrapassa 2 t/ha. Fatores de solo, como acidez, baixos teores de Ca, Mg, Ρ e Κ e matéria orgânica, concorrem para reduzir as produtividades. O desenvolvimento de materiais genéticos melhorados busca contribuir na superação dessas limitações. Como atividade inicial em um programa de melhoramento genético, o presente estudo avaliou um total de 160 populações de milho, nas safras 1994/95, 1995/96 e 1998/99, nos municípios de Pedro Afonso e Gurupi, em termos de produtividade de grãos (PG), altura da planta (AP), altura da espiga (AE) e dias para florescimento feminino (FF). Para PG, os efeitos de populações foram significativos em todas as avaliações, ocorrendo produtividades entre 1,59 t/ ha a 7,46 t/ha.

As diferenças nas performances produtivas e agronômicas em Pedro Afonso e Gurupi, juntamente com efeitos significativos das interações populações χ locais, alertam para a condução de programas de melhoramento específicos para cada local.
Seasonal changes of leaf Nitrogen content in trees of Amazonian floodplains
Authors: PAROLIN Pia , ARMBRÜSTER Nicole , JUNK Wolfgang J.
Published: June 2015

In Amazonian floodplains the trees are exposed to extreme flooding of up to 230 days a year. Waterlogging of the roots and stems affects growth and metabolic activity of the trees. An increased leaf fall in the aquatic period and annual increment rings in the wood indicate periodical growth reductions. The present study aims at documenting seasonal changes of metabolism and vitality of adult trees in the annual cycle as expressed by changes of leaf nitrogen content. Leaves of six tree species common in floodplains in Central Amazonia and typical representants of different growth strategies were collected every month between May 1994 and June 1995 in the vicinity of Manaus, Brazil. Mean leaf nitrogen content varied between 1.3% and 3.2% in the non-flooded trees. Three species showed significantly lower Ν content in the flooded period (p=0.05, 0.001, 0.001), the difference ranging 20-25% lower than in the non-flooded period. Two species showed no significant difference while Nectandra amazonum showed 32% more Ν in the flooded season (p=0.001). Leaf nitrogen content was generally high when new leaves were flushed (in the flooded period) and decreased continuously thereafter in all species. Three species showed an additional peak of nitrogen during the first month of the terrestrial phase, in leaves which had flushed earlier, indicating that flooding may disturb nitrogen uptake.

As baixas taxas de sobrevivência de adultos (26%) alimentados com Azolla sp. e de ninfas (40%) e adultos (30%) em L. natans indicam que estas plantas podem representar recursos alimentares alternativos. Experimentos com P. stratiotes e S. auriculata dentro de gaiolas flutuantes, no campo, sem P. acuminata, resultaram num aumento do peso fresco das plantas (51-64%). Com 20 gafanhotos (ninfas e adultos) houve decréscimo de peso (40-45%). Estes dados reforçam o potencial dc P. acuminata como agente de controle biológico de macrófitas aquáticas específicas.

Authors: Silva Diego Augusto Santos , Nunes Heloyse Elaine Gimenes
Published: June 2015

OBJECTIVE: To estimate the prevalence of underweight, overweight, and obesity among children who were beneficiaries of the Brazil's conditional cash transfer program Bolsa Família during 2010, according to gender and health in the state of Mato Grosso do Sul, Brazil. METHODS: Descriptive epidemiological study was conducted with a secondary database of Datasus/Sisvan. The data from 19,289 children (9,451 girls and 9,838 boys), aged 5 to 10 years, who benefited from the program Bolsa Família in the state of Mato Grosso do Sul in 2010 were collected. The variables were body weight and height. Body mass index was analyzed with Z-scores of normative tables from the World Health Organization. RESULTS: The prevalence of underweight was 4.8% among female and 5.6% among male participants. The prevalence of overweight and obesity was, respectively, 14.8 and 9.1% for female participants and 16.1 and 11.9% for male participants. The prevalence of underweight and obesity was lower in cities/towns with a lower Human Development Index, for female and male individuals. The prevalence of overweight in cities/towns with a lower Human Development Index was lower among female participants and higher among male participants. CONCLUSIONS: The higher prevalence of overweight among individuals of lower socioeconomic status indicates the need for understanding macro-factors that can influence the children's nutritional status.

Authors: Costa Filho José Luciano Lopes da , Prata Bruno de Athayde
Published: June 2015

Abstract O problema de programação de caminhões é um tema de grande relevância na gestão de frota das empresas. Estas enfrentam dificuldades em gerenciar seus veículos devido às diversas variáveis inerentes ao processo, tais como o tamanho ideal da frota, os diversos tipos de caminhões disponíveis, a capacidade de carga do caminhão, as informações técnicas do cliente e o agendamento das viagens. No que se refere ao transporte de derivados de petróleo, existem diversas características operacionais que dificultam a programação de caminhões. O presente trabalho tem como objetivo desenvolver um modelo de programação inteira para a otimização da programação de veículos de múltiplos tipos para o transporte de derivados de petróleo para obras de construção de rodovias. Foi desenvolvido um modelo que buscasse a minimização da frota de caminhões disponíveis. Como conclusões, pode-se ressaltar que a metodologia empregada serviu para minimizar em 23,3%, em media, a frota necessária no período analisado. O desenvolvimento de indicadores de desempenho permitiu avaliar a qualidade das soluções geradas.

A Norma das Constituições e a Constituição da Norma no século XIX
Authors: Pagotto Emilio Gozze
Published: June 2015

O texto apresenta os resultados de um estudo comparando os dois primeiros textos constitucionais brasileiros:  a constituição do Império, de 1824 e a constituição da República, de 1891. A comparação entre os dois textos permite concluir que teria havido, no espaço de tempo decorrido entre os dois textos, uma alteração significativa nos padrões normativos daquilo que se concebe como boa ou má língua, ao menos quanto às construções aqui examinadas. De fato, quanto à posição dos pronomes clíticos, quanto ao emprego de preposições em completivas e relativas, quanto ao emprego do relativo onde, dentre outras construções, percebe-se uma clara diferença de preferência entre um e outro texto constitucional. Elas materializam a passagem entre o que se costuma chamar de português clássico e o que se costuma chamar de português moderno, este último entendido aqui como o português normatizado que se recomenda nos manuais de gramática.Tal passagem de uma norma a outra se dá, no Brasil, à revelia dos processos de mudança em curso e na direção que redundará no português brasileiro atual.
Statistical Models for Analysis of Social Network Dynamics in Educational Studies
Authors: Dokuka Sofia , Valeeva Diliara
Published: June 2015

Research on co-evolution of networks and behavior became possible with the emergence of student performance and behavior dynamic data collection and storage tools, as well as with the development of new social network analysis methods. Dynamic network analysis answers the question, how specific forms of student behavior, like bad habits, develop and propagate. It is also helpful in following how school or university students enter into friendship or antagonism with each other, as well as in assessing the impact social relations have on academic performance. The paper gives a review of the two key methods used for empirical analysis of social network dynamics. Stochastic Actor-Oriented Models (SAOM) represent one of the most elaborated  techniques of social network dynamics investigation. This approach regards the present state of a network as dependable on its preceding state uniquely. Network evolution appears to be continuous, not discrete, so that a structural macro change is, in fact, a multitude of micro changes. Instead of dealing with structure of the network and prerequisites for its development, the SAOM model studies the processes underlying any changes recorded. Separable Temporal Exponential Random Graph Models (STERGM) are an alternative approach towards research on social network dynamics. In this case, the social network observed is a materialization of one of possible networks with predetermined characteristics. Any network develops in the result of a stochastic process, and the research should be aimed at discovering what forces this process is driven by. Comparison of an empirically discovered network with networks of similar size reveals structural features of the network and characteristics of actors who influenced the process of its establishment. In this paper, we also give an example of how both models can be used with the same set of data.
International Accreditation: Are We There Yet?
Authors: Steve O. Michael
Published: June 2015

With the increasing internationalization of higher education and the explosion in the number of students and faculty studying, researching, and teaching outside of their home countries, global standards for educational quality control have become an imperative. The most effective approach to quality control within institutions of higher education, the paper argues, is voluntary accreditation — periodic internal reviews that are externally validated. Accreditation is a uniquely American creation, but it is gaining currency in other countries as well. The paper discusses the potential benefits of international accreditation, which would facilitate collaboration between accredited universities located in different countries. The practice of accreditation is contrasted with the practice of ranking, which is presented as a commercial exercise that does a poor job of measuring the actual institutional quality and that is ultimately based on the personal opinions of the people doing the ranking. Finally, the potential challenges that international accreditation faces (including unwillingness of the creators of the current quality industry to yield power to a global  ccreditation agency, among other things) are presented as temporary obstacles.
The Social Philosophical Dimensions of Hospice Care
Authors: Powell Jason L.
Published: June 2015

Hospice care is a type of care and philosophy of care that focuses on the palliation of a terminally ill or seriously ill patient's pain and symptoms, and attending to their emotional and spiritual needs (Powell 2014). The concept of hospice has been evolving since the 11th century. Then, and for centuries thereafter, hospices were places of hospitality for the sick, wounded, or dying, as well as those for travellers and pilgrims (Dossey 1999). The modern concept of hospice includes palliative care for the incurably ill given in such institutions as hospitals or nursing homes, but also care provided to those who would rather spend their last months and days of life in their own homes (McCue and Thompson 2006).
Les échanges en ligne comme secteur de pratiques et de recherches en ALAO: quelles problématiques, quelles évolutions?
Authors: Mangenot François
Published: June 2015

Depuis une dizaine d’années, la thématique de la télécollaboration, des échanges interculturels en ligne ou de la communication médiatisée par ordinateur en langues tient une place croissante dans le champ de l’ALAO (apprentissage assisté par ordinateur). Cet exposé proposera à la fois un panorama et un bilan intermédiaire de ce domaine de pratiques et de recherches. Pour la dimension « panoramique », après avoir présenté un historique du domaine, on proposera une typologie des échanges en ligne fondée à la fois sur le dispositif adopté et sur l’objectif principal visé. Pour la recherche, on évoquera, de manière sélective, quelques problématiques qu’abordent plus particulièrement les chercheurs européens, pas toujours bien connus outre-atlantique : distinction entre mutualisation et collaboration, effet des outils synchrones ou asynchrones sur la communication, dimension socio-affective du tutorat.
Balados sur les stratégies d’écoute et de prise de notes pour les étudiants d’immersion en français au niveau universitaire : de la conception à l’évaluation des impacts
Authors: Knoerr Hélène , Weinberg Alysse
Published: June 2015

Plusieurs études ont suggéré la baladodiffusion comme outil pédagogique pour améliorer les compétences d’écoute en langue seconde (L2) au niveau universitaire. cette optique, nous avons développé une série de sept balados ancrés dans la théorie métacognitive et la théorie de l’écoute en langue étrangère présentent des stratégies d’écoute en L2 et des techniques de prise de notes. Ces balados ont été proposés à 161 étudiants inscrits dans 21 classes du Régime d’immersion en français de l’Université d’Ottawa. Nous avons ensuite mesuré leur impact sur les stratégies d’écoute et de prise de notes des étudiants. Les résultats sont mitigés, avec certaines améliorations plus ou moins significatives sur le plan quantitatif, et d’autres plus marquées sur le plan qualitatif.
Immersion studies at the University of Ottawa: From the 1980s to the present
Authors: Burger Sandra , Weinberg Alysse , Wesche Mari
Published: June 2015

This article traces the history of content-based language teaching at the University of Ottawa from its early roots in sheltered and then adjunct courses in ESL and FLS to the current large-scale French Immersion Studies (FIS). It places content-based language learning at the University in the context of somewhat similar initiatives in the Canadian school situation and in some U.S. universities. The writers show how insights gained from the earlier sheltered and adjunct experiences led to development of the pedagogy and administrative support of the FIS. Issues discussed include the training and orientation of language instructors, criteria for selecting discipline professors, challenges students face and institutional support for students. They also address continuing weaknesses of the program.
L’expérience étudiante au Régime d’immersion en français : perspectives et constats
Authors: Lamoureux Sylvie
Published: June 2015

Aux États-Unis comme au Canada, les recherches sur la transition aux études postsecondaires et l’expérience étudiante ont tendance à se concentrer sur l’étude des populations majoritaires (anglophones) qui étudient dans des programmes universitaires de langue anglaise dans des établissements anglophones. De plus, ces études ont tendance à utiliser quasi exclusivement des données quantitatives. Les résultats présentés ici viennent combler une lacune importante dans le domaine de la recherche sur les études postsecondaires en permettant une meilleure compréhension de la transition et de l’expérience étudiante de jeunes francophiles qui étudient en français dans le Régime d’immersion de l’Université d’Ottawa, du point de vue des étudiants eux-mêmes.
A study of the consumption pattern in a continuous water service demonstration zone and bulk water demand forecasting for Hubli-Dharwad, India
Authors: Jayaramu K. P. , Burt Zachary , Manoj Kumar B.
Published: June 2015

In the year 2008, the Karnataka Urban Water Sector (KUWS) Improvement Project brought continuous water service (CWS) to a demonstration zone in the twin cities of Hubli-Dharwad, India. Scale-up of CWS for the rest of the city has been authorized and the initial stages of construction are currently in progress. We compared the historical consumption pattern in the CWS demonstration zone of Hubli with system capacity. We found that demand in the demonstration zone has stayed within system capacity and below the national standards for adequate supply. We developed two forecast models of bulk water demand under CWS and compared forecasts with planned future system capacity. In the case of full scale-up of CWS to the rest of Hubli-Dharwad, our forecasts indicate that planned system capacity may be insufficient to meet bulk demand. These forecast models can be adopted by similar mid-sized cities in India.
Reliability and validity of Serbian version of children's dental fear questionnaire
Authors: Lalic Maja , Aleksic Ema , Milic Jasmina , Malesevic Adam , Jovicic Bojan
Published: June 2015

Background/Aim. Dental anxiety leads to avoidance of dental treatment and
could lead to impaired oral health. The aim of this study was to determine
the reliability of the Serbian version of Children?s Fear Survey Schedule
Dental Subscale (CFSS-DS) and the relations between dental anxiety and oral
health status in a sample of Serbian schoolchildren. Methods. The CFSS-DS
scale was translated into Serbian and administered to 231 (12-year old)
patients of the Pediatric Dental Department, Public Health Center Cukarica,
Belgrade. The number of healthy, decayed, missing and filled teeth (DMFT
score) in children was determined by a clinical exam. Results. The average
CFSS-DS score was 26.47 ? 10.33. The girls reported higher anxiety than the
boys (p < 0.05). Most common fears were drilling, choking, going to the
hospital and anesthesia. Lower CFSS-DS scores were recorded in children with
all healthy teeth (p < 0.05). Children with higher CFSS-DS scores mostly
visit the dentist due to pain or parental insistence, and those with lower
anxiety scores more often visited dentist due to regular check-ups or
non-invasive treatments (p < 0.01). A high value of the Cronbach's
coefficient of internal consistency (? = 0.88) was found in the entire scale.
Conclusion. The Serbian version of CFSS-DS questionnaire is reliable and
valid psychometric instrument for evaluation of dental fear in Serbian
children. Dental anxiety negatively affects dental attendance and oral health
of the examined schoolchildren.
Airport Traffic and Metropolitan Economies
Authors: Lakew Paulos Ashebir
Published: June 2015

While controlling for the unique and unobserved characteristics of cities, this paper assesses the impact of urban size, employment, and income on air traffic. Previous studies have established links between the socio-economic characteristics of cities and the volume of passenger and cargo traffic enplaned at their airports. Using the variations of population, employment, and income across urban areas, researchers have found that passenger enplanements have been proportional to city size and that they have increased with income and service sector employment. However, most earlier work relied on cross-section methods that ignored city-specific differences that may have influenced the drivers of air traffic. This paper is based on a 10-year quarterly panel of city-level economic and traffic measures, from which a city fixed-effects model is estimated. Thus, the results presented here shed light on the within-city effects that population, employment composition, and the average wage have on traffic and provide new insights into the determinants of air travel and goods movement. Controlling for the unobserved features of a metropolitan area, the paper confirms that passenger and cargo enplanements are proportional to population. Service sector employment and higher wages, indicating white-collar jobs, continue to induce both passenger and cargo transport, while a city's share of employment in manufacturing (blue-collar) jobs mostly affects cargo traffic. Furthermore, the fixed-effects results show that passenger enplanements exhibit more sensitivity to the proportion of urban workers providing nontradable services than to the share of workers in tradable service jobs.

Resolution of precocious puberty following resection of fourth ventricular medulloblastoma: case report

Published: June 2015

Medulloblastoma is a malignant embryonal tumor that arises in the cerebellum and invades the fourth ventricle, often resulting in obstructive hydrocephalus. Patients typically present with symptoms related to increased intracranial pressure and cerebellar dysfunction. The authors report a rare case of classic medulloblastoma with central precocious puberty (CPP) as its only presenting symptom.

A 7-year-old boy with no prior history of medulloblastoma presented with Tanner Stage IV testicular enlargement and a 4-month history of acne and pubic hair. Laboratory tests of blood samples demonstrated highly elevated luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone. Admission MRI of the brain revealed a mass in the posterior fossa, which bordered and compressed the fourth ventricle. The patient also exhibited mild lateral and third ventriculomegaly. Surgical options were discussed with the neurosurgical department.

A suboccipital craniotomy and C-1 laminectomy were performed. A large mass was seen arising from the inferior surface of the vermis, and lying within the fourth ventricle. Gross-total microsurgical resection of the mass was performed. Histopathological investigation characterized the tumor as classic medulloblastoma. Follow-up laboratory tests of blood samples demonstrated a reduction of LH, FSH, and testosterone back to prepubertal levels. The patient then began radiation and chemotherapy.

This report demonstrates that mild obstructive hydrocephalus due to a posterior fossa tumor may present with unexpected symptoms, such as CPP. To the authors’ knowledge, precocious puberty has not yet been associated with medulloblastoma, although it has been found with other posterior fossa tumors. Extensive imaging of the CNS for patients presenting with CPP is recommended.
