Az alacsonynak tűnő kockázat elhanyagolása a sportfogadásokban
Authors: Boda Márton Attila
Published: March 2018

A dolgozat a sportfogadásban és úgy általában a szerencsejátékok során megjelenő legnépszerűbb stratégiákat mutatja be, melyek célja, hogy alkalmazásukkal a játékos stabil profitot érjen el hosszú távon. Ugyanakkor a stratégiák alapvetően nem alkalmazhatóak hosszú távon nyereséggel. Mégis ezt az ígéretet sajnos sok játékos elhiszi és bízik a különböző fogadási stratégiák működőképességében. A dolgozatban Monte Carlo szimulációval vizsgálom a martingál, a d’Alembert, Paroli és Labouchère stratégiát. A különböző stratégiák esetén bemutatom, hogy mi nyeri meg a játékosokat azok alkalmazására és hogy hol vannak ezen stratégiák problémás pontjai. Ezután megvizsgálom, hogy a labdarúgást érintő sportfogadások esetén mekkora a tippelési sikerarány különböző erősségű ellenfelek esetén. Végül bemutatom a két legfontosabb problémáját a különböző fogadási stratégiáknak, amelyek a kockázatok rossz becslése és a források végessége. A stratégiákban való hitnek legfőbb okaként az elérhetőségi heurisztikát jelölöm meg.
Basic characteristics and quality of virgin olive oil produced in Corfu (cv. Lianolia) and South Albania (cv. Kalinioti)
Authors: Demertzi Konstantoula Akrida , Roukos Christos , Demertzis Panagiotis
Published: March 2018

In the present study the qualitative characteristics such as peroxide number, absorption coefficients (K232, K270), acidity, total phenols, a-tocopherols, chlorophylls and composition of fatty acids were determined in 19 virgin olive oil samples of “Lianolia” variety cultivated in Corfu and “Kalinioti” variety cultivated in South Albania, harvested in the crop year 2013/2014.

Obtained results indicate that all olive oil samples show chemical and physicochemical parameters included in the limits established for virgin olive oils and some of them in the limits for “extra” virgin olive oils.

Moreover it was found that the qualitative characteristics of olive oil samples are affected by variety, fruit treatment and the method of olive harvesting (in Corfu olives are collected by hands from plastic nets under the trees, whereas in Albania they are basically collected by hand after falling on the ground). The results of the present study are a first indication of the olive oil quality produced in Corfu and South Albania.

Published: March 2018

Though, a lot of emphasis has been put to decentralize financial institutions to offer agricultural credit, access to credit in many rural households in Rwanda remains limited, so far no study done in the study area on institutional factors influencing the decision to take credit. This study investigated the institutional factors influencing the decision to take credit among smallholder coffee farmers in Gisagara District, Southern Province of Rwanda. A Multi stage sampling techniques was employed to select respondents. Primary data were drawn from222 smallholder farmers using structured questionnaires.Binary logistic regression was employed to estimate the data. The results indicated that the institutional factors which influenced access to credit were cooperative membership, extension services, information on credit use, fear take risk and distance to coffee washing station. Based on the findings of the study, recommended that in order to increase access to use agricultural credit there is need to focus in organizing coffee producers in cooperatives, strengthen the current strategies of extension, education and infrastructural services particularly for road transport.
Adsorptive Removal of Bromophenol Blue Dye from Aqueous Solution using Acid Activated Clay
Authors: C. C Okoye, , C. F Okey-Onyesolu , D. C Chime , C. C Achike
Published: March 2018

Sulphuric Acid Activated River Niger (SAARC) adsorbent was prepared and used for the treatment of simulated wastewater. The merits of the chemical activation were evident on the characterization results. The morphology of the clay suggested that it belongs to the kaolinite family. Experiments conducted show the percentage of Bromophenol blue (BB) dye adsorbed on SAARC significantly depends on pH, adsorbent dosage, contact time, temperature and dye concentration. Langmuir model best fitted the experimental data compared to the results obtained for Freundlich, Temkin and Dubnin-Radushkevich isotherm models. The Dubinin-Radushkevich isotherm , E, depicts that the adsorption process is physisorption in nature. The experimental data were better described by the pseudo-second order and the power function kinetics models. The feasibility and spontaneity, exothermic nature and decreased randomness at the solid-solution interface were confirmed by the negative values calculated for Gibb’s free energy (ΔG∘), enthalpy change (ΔH∘) and entropy change (ΔS∘) respectively. The results obtained corroborate the potential suitability of the prepared sulphuric acid activated River Niger Clay (SAARC) as an adsorbent

Even though it is taught and used in many countries all over the world there is a lack of emprical research and psychometric assesment on Eneagram classification system of personality. This study aimed to contribute the this literature and present some evidence as well as developing a valid and reliable inventory. Research sample consisted of 21140 young and adults and data were randomly divided into two groups with an aim of conducting principal component analysis and confirmatory factor analysis for each data set. As a result the inventory formed with 72 items and it can be said that it has high item-factor loadings, and each dimension measures the characteristics intended to measure while explaining the variance at an acceptable level. Many of the findings indicated a good fit. Sufficient internal consistency values were obtained in all dimensions. All these findings indicate that the inventory has sufficient reliability and validity values.
Perceptions of Chinhoyi University of Technology’s staff and students regarding the Communication Skills course
Authors: Nembaware Shadreck
Published: March 2018

This study explores the myriad of perceptions, perspectives, attitudes, approaches and conceptions about the module Communication Skills (CUACE101) which is a campus-wide compulsory course taught to all Chinhoyi University of Technology first year first semester (1.1) students. The motivating factor for this study has been an endless debate on the merits of the course to a university curriculum whose niche and mandate is predominantly technology-oriented, hence the need to establish the rationale for a communication course appropriately packaged to yield not only a fully qualified graduate but also a wholesome citizen whose harmonious combination of well-accentuated faculties fits them for an indelible impress on a career terrain tilted in the direction of twenty-first century global imperatives. The research thus motivates for a perceptive shift from a fragmented and compartmentalized view of a university graduate, embracing rather the merits of higher education’s systemic vision driven by a synthesis of multi-disciplinary curriculum design dynamics. Inspired by the Reconstructionist philosophy, this qualitative exploratory study yields a taxonomy of themes and trends by respondents from various disciplines at Chinhoyi University of Technology, necessitating a broad-based and holistic approach to university curriculum programming. The global currents have triggered a paradigm shift from the instruction of communication as a course in commonplace literacy fundamentals (reading, speaking and writing skills) to a more nuanced discipline that factors in a host of globalization-compliant dynamics like information literacy skills, critical thinking skills, people skills, cultural literacy, technopreneurial skills, communicative competence and corporate wisdom. The study deploys focus group discussions (for CUACE101 students) and CUT schools deans questionnaires, triangulating qualitative methods to establish key internal stakeholder perceptions on the campus-wide course (Communication Skills). The study’s findings map out a blue-print for influencing policy and practice in curriculum design, implementation and review

Dignidade humana: proposta de uma abordagem bioética baseada em princípios
Authors: Albuquerque Aline
Published: March 2018

A ideia de que a dignidade humana é um valor não se mostra suficiente para conferir-lhe operabilidade, assim é necessário que dela se emanem comandos normativos como o princípio do respeito à pessoa; o da não instrumentalização e o da vedação do tratamento humilhante, desumano ou degradante. Sob o prisma metodológico, esta pesquisa caracteriza-se como teórica com base no levantamento da literatura bioética sobre a temática. Concluiu-se que os princípios do respeito à pessoa; da não instrumentalização e da vedação do tratamento humilhante, desumano ou degradante são comandos normativos operativos aptos a materializar a dignidade do paciente. Desse modo, a reflexão bioética sobre os cuidados em saúde do paciente sob a perspectiva da dignidade humana há que tomar em conta os princípios objeto desta investigação, servindo de fundamento ético relevante para a análise de questões éticas levadas a cabo por instâncias de deliberação moral
Releitura crítica (social e política) do princípio da justiça em bioética
Authors: Garrafa Volnei , Manchola-Castillo Camilo
Published: March 2018

Este artigo apresenta uma releitura crítica do princípio da justiça em bioética, que pressupõe ir além do usual legalismo jurídico. Propõe-se fazer uma leitura social e política do princípio, a partir da relação existente entre bioética e direitos humanos, legitimada suficientemente pela aprovação, por unanimidade, da Declaração Universal sobre Bioética e Direitos Humanos da UNESCO em 2005. A dimensão social da justiça em bioética é argumentada por meio da discussão da equidade e do tema do meio ambiente, e a dimensão política, por sua vez, por meio da discussão das categorias empoderamento, emancipação e libertação. Conclui-se que uma releitura crítica do princípio da justiça em bioética é necessária para a construção de uma bioética justa, democrática e cidadã.
Social Media a Two-Edged Sword to E-Governance: The Role of Social Media in Cameroon’s Democracy
Authors: Nseke Pisso
Published: March 2018

The aim of the paper is to provide information about the application of social media tools in e-governance of Cameroon. The review of the literature shows that social media tools have a huge potential to be used in the context of e-governance and it offers several benefits such as transparency, easy and wide dissemination of information about the activities of government and many others. However, there are still some countries which have not taken full advantage of benefits offered by social media in the context of e-governance. Although there are a number of countries including Cameroon which has adopted usage of social media tools in e-governance, the interaction and engagement of customers to e-governance systems is rather limited and needs further development. This paper aims to provide information about the current state of e-governance in Cameroon which is explained by the framework of social media policy which consists of eight important elements.
Znaczenie wybranych czynników ekonomiczno‑społecznych dla kształtowania stabilności fiskalnej gmin miejskich w Polsce
Authors: Wójtowicz Katarzyna
Published: March 2018

Celem artykułu jest ocena wagi wybranych czynników ekonomiczno‑społecznych w kształtowaniu stabilność fiskalnej gmin miejskich w Polsce. Próba badawcza objęła 241 takich gmin, a zakres czasowy badania dotyczył lat 2004–2016. W artykule wykorzystano metodę ekonometrycznego modelowania danych panelowych. Przeprowadzona analiza wykazała, że zakres związku między potencjałem społeczno‑gospodarczym badanych JST a ich sytuacją finansową okazał się zdecydowanie mniejszy, niż można byłoby oczekiwać. Wpływ na ten stan rzeczy wydaje się mieć uzależnienie budżetów samorządowych od transferów zewnętrznych oraz wysoki udział wydatków sztywnych, jak również istnienie tzw. miękkich ograniczeń budżetowych, które gwarantują otrzymanie pomocy finansowej z budżetu centralnego w przypadku zagrożenia niewypłacalnością.
Luxury Fashion Brands and Furniture Design: Investigating Strategic Associations
Authors: Codignola Federica
Published: March 2018

The recent phenomenon of the modest growth in the personal luxury goods market has created an urge to face difficulties through innovative brand and marketing communication strategies. This paper examines the potentialities of strategic associations between luxury fashion brands and furniture design. The research question to be here examined is whether synergies with furniture design can represent possible innovative strategic instruments useful to compete in the global sector of the luxury fashion industry. To do so, this paper firstly examines the congruencies and the existent associations between fashion and design. Secondly, it compares luxury fashion brands with the specific furniture design market in order to verify whether and how such inter-sectoral convergence may effectively produce fluxes of value. Results indicate that the association between luxury fashion brands and collectible furniture design in particular is the most fruitful. The value of luxury brands is enhanced and consumers are provided at the same time with innovative and creative luxury experiences.
Consumer Awareness and Consumer Protection in Hungary
Authors: Szucs Robert Sandor
Published: March 2018

The consumer asserts that his decisions are consistent and rational. He likes to believe this about himself. Based on previous surveys it can be stated that our confidence persists until the assessment of the actual level of our knowledge on consumer protection takes place, e.g. in the form of a test containing 13 substantial questions to measure the actual level of knowledge. This test was filled out by 2182 persons over 18 years of age. In overall, we can say that no matter how much we love to think about ourselves as being conscious customers, this statement is generally not true. The level of consumer protection knowledge is generally insufficient in Hungary. Only 13% of consumers have the right to say that they are knowledgeable of consumer protection at average level, while the good level was achieved only by 2.1% of the respondents.
Private Law Issues of Concession and Investment within the Framework of Public-Private Partnership
Authors: Khatidze George
Published: March 2018

Concession is one of the forms of public-private partnership. Financial sources, on the other hand, for many public-private partnership projects are generated by private investment. Both concession and investment play a significant role within the public-private partnership. Analysis of the Law of Georgia on Concession with relevant laws of the other countries clearly underlies that institutional and legal mechanism of concession relations in Georgia do not comply with the best international standards established in many other countries. Law of Georgia on Investment also contains certain shortcomings in that respect. Therefore, it is necessary to improve and further develop private law norms of concession and investment in order to create those institutional and private law basis which are vital for implementation of public-private partnership.

Published: March 2018

Enteric CH4 emissions have been of great scientific interest as they represent a real energy loss for livestock and are also responsible for global warming. The objective of this study is to measure enteric methane emissions in farm animals, and then develop models for estimating quantities emitted based on the amount of dry matter ingested (MSI). Holstein cows (n = 38) received dietary rations of 50% forage and 50% feed concentrate, and a linear regression model was developed to predict CH4 production per animal (g). CH4 (animal / day) from the amount of dry matter ingested and the equation obtained was as follows: Y = 19.05X. Here, Y is the amount of CH4 (g CH4 / cow / day) and X is the amount of ingested dry matter (kg), with R² = 0.91, r = 0.97, and RMSPE = 5.53%. For small ruminants (n = 22), three dietary levels were used and methane production was measured. In addition, the equation obtained was: Y = 12.21 X with R² = 0.81, r = 0, 91 and RMSPE = 15.80%. In camelins (n = 12) and equines (n = 10), only one food level was used and methane measurements did not develop an estimation model. However, mean values of methane production were determined and they corresponded to 11.41 g CH4 / kg MSI in camels and 2.18 g CH4 / kg MSI in horses.

Introduction: The aim of this work was to highlight the therapeutic and prognostic difficulties between a laparoscopic cholecystectomy for acute gallstone cholecystitis (CAL) and uncomplicated symptomatic vesicular lithiasis (LVS) as well as the reasons for conversion to laparotomy. Patients and Methods: This was a prospective comparative and analytic study over 18 months. Patients admitted and operated for CAL or LVS in the A Surgery Department of the National Hospital of Niamey (HNN) were included. Results: The study involved 61 patients divided into two groups. Group 1 (30 patients) corresponding to patients operated for CAL, group 2 (31 patients) corresponding to patients operated for LVS. Laparoscopic cholecystectomy accounted for 61% of all cholecystectomies performed and 1.45% of surgical activity during the same period. The average age in group 1 was 43.7 years with extremes of 14 and 61 years. In group 2, the average age was 38.9 years with extremes ranging from 12 to 55 years. Women were predominantly represented with 63.3% and 96.7% respectively for groups 1 and 2. Patients were overweight in 9 cases for group 1 (30% of cases) and 12 cases in group 2 (38%), 7% of cases). Hepatic colic was the main sign of appeal in all patients in both groups. In group 1; 26 out of 30 cases or 86.7% of cases had leukocytosis, whereas in group 2, leukocytosis was normal in 30 cases, ie 96.8% of cases. Accessibility of the vesicle was difficult in 73.3% of cases in group 1 against 22.6% of cases in group 2. The vesicle was distended and necrotic in groups 1 in 76.7% and 10 respectively. % of cases. On the other hand, in 25.8% of cases, the vesicle was distended and without any necrosis in group 2. The rate of conversion to laparotomy was 6.55% (4 cases) and exclusively concerned group 1. Operative follow-up immediate outcomes were simple in 98.34% of cases. The complications involved 2 patients in group 1 (1.66% of the total), including parietal suppuration and biliary leakage. Mean operative time was 68.7 min in group 1 versus 41.6 min in group 2. Mean duration of hospitalization was 4.3 days with extremes between 2 and 10 days in group 1 versus1,7 days with extremes ranging from 1 to 7 days in group 2. Mortality was zero. Conclusion: In recent years, laparoscopic surgery has made remarkable progress in Niger. Laparoscopic cholecystectomy seems to be more difficult to perform with significant morbidity in the case of CAL than LVS. The risk of per and postoperative complications can be estimated from the clinical data (acute cholecystitis or symptomatic vesicular lithiasis) and the surgeon's experience. In a cholecystectomy that lasts more than 2 hours, the cumulative risk of complications is higher

Background: Hepatitis B virus infection is considered a major worldwide public health problem. While adults that acquire acute infection usually recover, the chronic type is ultimately fatal both to them and their foetuses. In endemic areas, individuals are infected by vertical transmission or infection in early childhood. The seroprevalence rates of Hepatitis B in pregnancy vary according to the endemicity of a given area with very high prevalence rates mostly reported among developing nations in Asia and Africa. Objective: To determine the seroprevalence of hepatitis B surface antigen in pregnant women attending the antenatal clinic, identify the clinical and epidemiological correlates for hepatitis B in pregnancy and to make evidence based recommendations on screening protocols for our obstetric population at the Federal Medical Centre, Yenagoa. Methodology: This is a descriptive cross sectional study. Two hundred and twenty (220) consecutive healthy pregnant women attending the antenatal booking clinic of the hospital who met the inclusion criteria were recruited into this study after pretest counselling and obtaining consent from them. This was tested for HBsAg with commercially available in vitro diagnostic kits (one step test strips). Data was collected via a structured interviewer administered questionnaire. Data entry and analysis was done using SPSS (statistical package for social sciences) 22 statistical package (SPSS Inc., Illinois, U.S.A). P value less than 0.05 was European Scientific Journal February 2018 edition Vol.14, No.6 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 280 taken as being significant. Results: The mean age of the pregnant women studied was 28.8 years ± 5.2 while the mean parity was 1.20 ± 1.16. 220 pregnant women who came for antenatal booking were recruited into this study. Of these, 4.6% (n=10) were seropositive for hepatitis B surface antigen (HBsAg). Multiple sexual partners and Female circumcision were the significant risk factors for HBsAg seropositivity (p<0.05). There was no significant association with respect to a history of jaundice or contact with a jaundiced patient, previous blood transfusion, intravenous drug abuse or sharing of sharps, previous surgery, episiotomies or dilatation and curettage (p>0.05). Conclusion: The intermediate endemicity of Hepatitis B virus infection in this study according to WHO classification, justifies the need for routine screening in pregnancy to identify and treat the infection accordingly as this will reduce the mother to child transmission. Multiple sexual partners and female circumcision are significant risk factors associated with Hepatitis B virus infection in this environment. Active and passive immunization to infants of HBsAg seropositive mothers is advocated.

Achilles Tendon Rupture (ATR) is a frequently described lesion in sports traumatology. It can occur following certain chronic or systemic diseases. We reported a case of a 48-year-old woman, a teacher by profession, who was consulting for lameness. Anamnesis found during a walk, a brutal sensation of blow on the heel with cowardice and sharp pain at the elective point imposing upon the resting of the patient. Clinical examination noted an increased spontaneous dorsiflexion of the affected ankle, depression corresponding to the tendon continuity solution, and a positive Thompson test. The diagnosis of Achilles Tendon Rupture was made. The patient was operated 2 weeks later by open surgery. A simple suture kept by a plaster splint was performed (the ankle in equinus). Functional rehabilitation was done for 6 weeks, and walking was allowed at the 6th week. In the absence of minimally invasive surgery, conventional surgery can provide good results in case of spontaneous Achilles Tendon Rupture at the cost of rigorous monitoring of the patient.

Published: March 2018

A finite size analysis of the Kondo lattice model with hybridization interaction between localized and extended orbitals using the exact diagonalization technique has brought more insight into the specific heat behavior of the heavy fermion (HF) systems under low temperature regimes. The specific heat under the antiferromagnetic region of temperatures below 3k is lower than that of the ferromagnetic region. While the specific heat for temperatures above 4k, shows a reversed trend.

The study was done on two species of peppers capsicumannuum and capsicum fructescens. It concerned ninety samples of these two species, collected during three countrysides in two localities of Côte d’Ivoire (Bouake and Dabou). These samples were handled by means of a liquid-phase leading chromatograph SHIMADZU with the aim of determining the residues of pesticides. The observed results revealed a contamination of both species : capsicum annuum and capsicum fructescens, indeed, six residues of pesticides (chlorothalonil, chlorpyrifos, carbendazim, maneb, dimethoate and lambdacyaholothrine) were detected in these two species distributed in four families of pesticides (organochlorines, organophosphates, carbamates and pyrethrinoïds). The analysis showed that pyrethrinoïdes with respective proportions of 76,17% and 75,95% in capsicum annuum and capsicum fructescens were the most important ; followed organophosphate with respective proportions of 10,93% and 20,04% in capsicum annuum and capsicum fructescens.The study also showed that the concentrations of residues of pesticides detected in the edible part (pericarp ) peppers are appreciably equal those found in the part inedible(pulp). However, the residues of pesticides detected in peppers of both localities have all average concentrations lower than the standards established by the Codex Alimentarius.

The aim of this study is to characterize the physicochemical parameters of the waters of certain continental wetlands and to determine the fish population diversity of this aquatic habitat in Mauritania. Physico-chemical analyses carried out in 2015-2016 (wet-fresh, hot-dry) suggest the qualities of good water, favorable to aquatic life at any time of the year. The highest values were recorded in the warm season (from 26.6 to 34.4 °C for the temperature, from 8 to 9.2 for the pH, from 170 to 591 μs/cm for the conductivity, from 3, 23 to 8.2 mg / l for dissolved oxygen and 169 to 590 mg / l TDS). The lowest values were found in the cold season (from 18.0 to 27.0 ° C for temperature, from 7.5 to 9.0 for pH, from 99.5 to 358 μs/cm for conductivity, 2.70 to 4.80 mg/l for dissolved oxygen and 100 to 360 mg/l of TDS). The establishment and development of biodiversity in these wetlands were at their peak during the hot and dry periods. 15 species belonging to 8 families were identified in these sites where there is a significant fishing activity. It is during this period that fish biodiversity and fishery potential increase as water decreases under the pressure of evaporation, infiltration and anthropozoogenic consumption. The ecosystem services of these continental wetlands, which survive the impacts of climate change, require urgent management, preservation and development measures.

Com base na teoria dos Arranjos Produtivos Locais (APL), as empresas buscam interações, a fim de atender suas necessidades e obter ganhos futuros. O presente artigo busca caracterizar as conexões estabelecidas entre os atores inseridos no APL têxtil da região metropolitana de São Paulo por meio da Análise de Redes Sociais (ARS). Trata-se de uma pesquisa descritiva para evidenciar as conexões estabelecidas entre as empresas do APL. A análise das medidas indicaram pouca cooperação e realização de negócios entre as empresas, de forma que as vantagens de participar do APL necessitam ser mais exploradas. Há necessidade de uma reflexão mais abrangente a respeito da atuação das empresas, dos agentes externos e das potencialidades locais.

Didactique professionnelle et formation à l’enseignement
Authors: Habboub El Mostafa
Published: March 2018

Resumo: Nas últimas décadas, para renovar a profissão docente, vários sistemas educativos no mundo, em particular os do Québec e da França, introduziram reformas dos programas de formação de professores. Em uma perspectiva de melhoria desses programas, alguns sistemas recorreram à didática profissional (DP) para melhorar a área do ensino e da formação dos docentes. Entretanto, o recurso à DP é recente. Visando esboçar um retrato do uso da DP no ensino e na formação dos docentes, o presente texto coloca em evidência os conceitos essenciais que emergem após o uso da DP, ou seja, situação, saber e atividade. Ele aborda a articulação entre esses três conceitos e tenta identificar suas contribuições conceituais para a formação.

Les didactiques peuvent-elles être critiques ? Apports des pédagogies et épistémologies sociocritiques
Authors: Thésée Gina , Carr Paul R.
Published: March 2018

Resumo: O presente artigo propõe uma outra racionalidade às didáticas com a noção de “didáticas críticas” (DC). Ele desenha um contra-relevo das didáticas fazendo surgir aspectos ocultos que elas rejeitam, não percebem, não problematizam, não questionam ou não teorizam. Diante das crises socioambientais que vivem as sociedades contemporâneas e diante das problemáticas e desafios que essas crises representam para a educação formal, as didáticas não podem mais ousar se apresentar como uma área estritamente disciplinar, descontextualizada, associal e apolítica, submetida somente aos critérios (ou mitos) da cientificidade, ignorando os males sociais (classismo, neocolonialismo, neoliberalismo, racismo, sexismo, conflitos armados, guerras, deslocamentos populacionais e outras violências) que, paradoxalmente, repercutem nas relações ensino-aprendizagem, objeto das pesquisas em didáticas. Mas, será que as didáticas podem ser críticas? Respondemos pela afirmativa. Nosso processo de teorização-conceitualização é baseado na teoria social crítica e na teoria racial crítica. As didáticas críticas são associadas à epistemologia e à pedagogia críticas como terceiro termo de uma “tríade crítica” da relação ensino-aprendizagem. Apesar de parecerem inusitadas nos dias de hoje, as DC fazem eco à pansofia de Comenius na “Magna Didactica” do século XVIII. A partir dessas perspectivas histórica e teórica-conceitual, evidenciamos algumas ancoragens das didáticas, elaboramos uma crítica das pesquisas em didáticas, apresentamos elementos de criticidade de uma pesquisa e propomos princípios axiológicos, ontológicos, epistemológicos e praxológicos para esboçar um campo socioeducativo promissor - “didáticas críticas” - para o ensino-aprendizagem, a pesquisa e a formação.

Contributions and limitations of three interpretative perspectives on the difficulties of teaching and learning mathematics at the elementary level
Authors: Rajotte Thomas
Published: March 2018

Résumé: Ce texte vise à mettre en lumière les apports et les limites des différentes perspectives qui relèvent de l’interprétation des difficultés d’enseignement et d’apprentissage en mathématiques des élèves du primaire. Cet article se situe plus précisément dans la foulée des recherches permettant de s’interroger sur la source fondamentale de ces difficultés. Un regard sur les écrits scientifiques, relevant principalement du corpus francophone des 30 dernières années, dégage trois perspectives principales qui permettent d’interpréter les difficultés qu’éprouvent les élèves en mathématiques. La première perspective attribue les difficultés d’apprentissage aux caractéristiques intrinsèques à l’élève. Cette perspective s’appuie sur les fondements des sciences cognitives. La deuxième perspective considère ces difficultés comme étant la résultante de l’interaction entre l’élève et le système didactique. Finalement, la troisième perspective se base essentiellement sur les fondements de la sociologie afin d’interpréter les difficultés des élèves en mathématiques. L’objet de cet article consiste à décrire les perspectives et à dresser un portrait des différents outils utilisés par les tenants des trois différentes perspectives explicatives des difficultés d’enseignement et d’apprentissage en mathématiques. De plus, une brève réflexion concernant la possibilité de réaliser un arrimage entre les différentes perspectives est mise en lumière à l’intérieur de ce texte.
Entre les pratiques prescrites, déclarées et effectives
Authors: Araújo-Oliveira Anderson
Published: March 2018

Resumo: O presente artigo visa identificar o estado da arte da pesquisa quebequense tratando do ensino das ciências humanas e sociais no primário[1], ressaltando suas contribuições e seus limites para alimentar a formação e a prática dos professores. A análise temática do conteúdo de 53 publicações científicas coloca em evidência a existência de uma pesquisa construtivista e inclusiva centrada numa visão crítica e reflexiva do ensino das ciências humanas e sociais no primário. No entanto, trata-se de uma pesquisa essencialmente descritiva que transita entre a lógica do sistema (práticas prescritas) e a lógica do sujeito (práticas declaradas). As práticas efetivas realizadas pelos professores e futuros professores em contextos complexos, assim como as atividades de aprendizagem realizadas pelos alunos (lógica da ação), são desse modo pouco estudadas. Nesse sentido, a articulação entre aquilo que é prescrito e declarado e aquilo que acontece concretamente na sala de aula é ainda pouco explorada.

Organic Solvent Free Process to Fabricate High Performance Silicon and Graphite Composite Anode
Authors: Xiao Haiqing , Zheng Tianyue , Liu Gao
Published: March 2018

Cycling reliability is crucial for Si-based materials due to severe volume change during cycles that results in the fast capacity fading. Though the binder only occupies a very low amount of the total mass of anodes, it is proved to perform a key parameter to improve the cycle performance of Si-based anodes. Because they are eco-friendly and cost saving, water-based binders styrene-butadiene rubber (SBR) and carboxymethyl cellulose (CMC) are regarded as the better binder to substitute Poly (vinylidene difluoride) (PVDF) as the binder for Si-based anode. In this study, the anodes are fabricated by simply mixing the active materials (naso Si, graphite and conductive additive) together and using the mixture of SBR and CMC as a binder. The results showed that the retention capacities of the anodes are more than 440 mAh/g after 400 cycles. It indicates that it is an easy and simple way to make high performance anodes.

This work shows the preliminary description of the origin of a sedimentary - exhalative outcrop of Jurassic Lower Pliensbachian. The location of this deposit was achieved by applying an examination based in the identification of sedimentary transgressions of heterochronies ages and the identification of a Rift – type mega –structure. According with the methodology, it was carried out a study of the discordant relationships between two types of sediments: continental and marine. According the characterization, it was noted the existence of light rare earths, in values that show positive anomalies in comparison with the distribution of elements in upper continental crust according to the Clarke [1], reflecting so a felsic affinity of the mineral deposit. Also, positive anomalies of platinum and Pd, were determined with marginal contents of Au and Ag; and finally the base metals Zn, Pb and Cu were detected in low contents, which could be due to the presence of altered shale. According to the sedimentary lithology found, which was of siliciclastic type; to the exhalative roots observed during the fieldwork; the presence of quartz minerals such as biotite and muscovite; the presence of minerals of hydrothermal remobilization like chalcopyrite with some base metals, altered shale, as well as sulfur deficiency; this mineral reservoir could be defined as a SEDEX – type.
