Neste artigo apresentamos aspectos sobre a elaboração, implementação e análise de uma estratégia didática alternativa para a resolução de exercícios/problemas em aulas de Física. A implementação dessa atividade foi realizada em duas escolas da rede pública na cidade de Joinville-SC, para estudantes da primeira série do Ensino Médio. A estratégia consiste em um jogo didático, em forma de tabuleiro, tendo como referência elementos do desenho animado "Corrida Malucaâ€. Os dados analisados, que compõem os resultados descritos neste artigo, foram obtidos a partir da gravação de áudio de uma equipe de estudantes e por meio de questionários respondidos pelos estudantes e professores implementadores do jogo. Dos resultados, observamos que a estratégia de utilizar um jogo didático em aulas destinadas a resolução de exercícios/problemas se torna um elemento potencializador do interesse dos estudantes na aula, auxiliando no processo de ensino-aprendizagem de conteúdos conceituais, procedimentais e atitudinais.

O objetivo deste artigo é operar com modos pelos quais a Etnomatemática vem sendo produzida no Grupo de Estudo e Pesquisa em Etnomatemática (GEPEtno), buscando apresentar, discutir e problematizar o Grupo como um território existencial que produz (na) Etnomatemática no mesmo compasso em que se produz. Para isso, utilizamos dois movimentos, que partem do presente em direção ao passado. No primeiro, falamos dos trabalhos produzidos no Grupo em nível de pós-graduação no Programa de Pós-Graduação em Educação Matemática (PPGEM) da Universidade Estadual Paulista (Unesp/Rio Claro); e, no segundo, discutimos a criação e a constituição do GEPEtno como grupo de estudo e pesquisa em uma universidade. Junto Ã composição desses movimentos e operando no bojo das Filosofias da Diferença, apresentamos uma discussão teórica sobre a processualidade do grupo, ora tomando-o como um território existencial - um ethos - que acolhe, ora como potência de diferenciação.

Assessment of Natural Radioactivity Levels and Radiation Hazards for Soil Samples Used in Erbil Governorate, Iraqi Kurdistan
Authors: Hussein Zakariya A. 
Published: May 2019

In this work, the activity concentrations of natural radionuclides 226Ra, 232Th and 40K in soil samples from Erbil governorate, Iraqi Kurdistan were investigated by a gamma-spectroscopy system based on high-purity germanium (HPGe) detector. This is to assess the dose of radionuclides exposure to the population, knowing the health risks and to have a baseline for future changes in the environmental radioactivity. It was found that the activity concentrations of 226Ra, 232Th and 40K were ranged from (14.6 ± 1.6 to 38.2 ± 2.8 Bq.kg-1), (4.5 ± 1.4 to 52.4 ± 5.8 Bq.kg-1) and ( 302.8 ± 12.6 to 388.6 ± 12.8 Bq.kg-1), respectively. The measured activity concentrations for these radionuclides were compared with the reported data of other countries and with the worldwide average activity of soil. Radium equivalent activities, absorbed dose rate, excess lifetime cancer risk and the values of hazard indices were calculated for the measured samples to assess the radiation hazard of the natural radioactivity in all samples to the people. It was concluded that the radium equivalent activities of the studied samples are below the internationally accepted values. These results show that annual effective dose absorbed via occupant from activity construction of soil samples used in the under place is below 1.0 mSv.y-1. It is concluded that the assessment radioactivity of soil are within acceptable levels and does not pose any health hazard to the population.

Financialization in the Regional Aspect. An Attempt to Measure a Phenomenon.
Authors: Gemzik-Salwach Agata , Perz Paweł 
Published: May 2019

Abstract
The aim of the work was to analyze the possibilities of measuring the phenomenon of financialization on a regional basis. The article attempts the move with the measurement of financialization from the level of countries to the level of regions. In the paper, some variables that can measure financialization at the level of voivodeships were used to create an index of regional financialization. The research proposal was verified empirically, using data from 2005–2015 for 16 Polish voivodeships. The results obtained allowed for the ranking of individual regions of the country, in terms of the degree of intensification of financialization. The regional approach is a subject, which is poorly recognized in the literature on the subject. However, according to the authors of the article, individual regions of the country may have a different degree of intensity of financialization, and knowledge on this subject may form the basis for strategic decisions regarding further development of these regions. The authors of the work wanted to pay attention to this issue and initiate further research in this direction. The presented methodology is only an attempt to measure this phenomenon and can be developed in subsequent studies.

Trade Openness and Carbon Emissions: Evidence from Central and Eastern European Countries
Authors: Ho Sin-Yu , Iyke Bernard Njindan 
Published: May 2019

AbstractUsing a composite trade share measure of trade openness, we examined the effects of trade openness on carbon dioxide emission for a sample of 17 Central and Eastern European (CEE) countries over the period 1994 to 2014. We found that high trade openness is associated with low carbon emission in the long run. When compared with the simple measure of trade openness (i. e. total trade as a percentage of GDP), the composite measure indicates that the effect of openness on carbon emission in the long run is smaller in absolute terms. Moreover, while high openness is associated with high emission in the short run using the simple measure, this association is non-existent when using the composite measure. These findings are robust to two historically closed economies and the recent Global Financial Crisis. When testing the Environmental Kuznets Curve (EKC) hypothesis using the composite measure, we found evidence in support of this in the long run. This finding connotes that high openness is associated with low emission in the long run, but up to a certain level of openness. That is, there is a turning point for openness beyond which further openness may spur high emission. Overall, our findings suggest, to some extent, that the measure of trade openness matters.

ZusammenfassungAusgehend von einigen sehr stark frequentierten städtetouristischen Destinationen und befördert durch eine intensive Medienberichterstattung über Besucherdruck und dadurch ausgelöste negative Effekte erfährt der Begriff „Overtourism“ und die Diskussion darüber seit 2017 eine hohe öffentliche Aufmerksamkeit. Die Diskussion ist dabei vor allem von einigen wenigen städtetouristischen Destinationen geprägt. Damit sich die Frage, inwieweit die sich an wenigen Extrembeispielen entzündende Diskussion als Hinweis auf eine zunehmende Ablehnung von touristischen Besuchern gesehen werden kann.Über städtetouristische Destinationen, die (noch) nicht im Fokus der medialen Berichterstattung stehen, ist bislang relativ wenig bekannt. Schaukeln sich hier ablehnende Haltungen auf oder gibt es Hinweise, dass neben der reinen Zahl von Besuchern auch andere sozio-kulturelle oder nachfragespezifische Aspekte relevant sind für die Akzeptanz von externen Besuchern,Mit dem Beitrag soll an einem Beispiel mit hoher Besucherintensität aber gleichzeitig noch geringen direkt sichtbar gewordenen negativen Haltungen der Bevölkerung, der Frage nachgegangen werden, welche Aspekte für die Einschätzung der touristischen Besucher relevant sind. Der Beitrag versteht sich dabei als Beitrag zu einer Versachlichung und sozialwissenschaftlichen Fundierung der medialen Diskussion.
Cement-Improved Wetting Resistance of Coarse Saline Soils in Northwest China

Published: May 2019

Abstract
Wetting-induced collapse of coarse saline soil foundations is a frequently encountered problem in the inland basin of Northwest China, but this particular behavior and relevant treatment have not been given adequate attention. Specimens treated by silicate cement were used in wetting collapse testing at conventional foundation loads, with five cement contents and four curing durations considered. The results indicate that in the case of no curing, the collapsible deformation during wetting declines at higher cement contents, and a stepwise development of deformation was noticed over the wetting duration. Specimens treated by cement after curing exhibit a decrease in the compressive deformation during wetting, and part of them show volume expansion instead. The complex hydrolysis and hydration reaction of cement in the process of curing primarily accounts for this. Moreover, the collapsibility coefficient varies within a narrow range in the noncuring case, proving the limited influence of cement inclusion; however, a gentle range, from 2.0 to 4.0 %, can be found after curing, beyond which it slightly varies. An elastoplastic model was established, incorporating a variable boundary seepage equation, and was then used for modeling a field immersion test. The rationality of the model was verified by comparing the measured and simulated results, including the degree of saturation and vertical displacement. The optimal depth and width for cement treatment was discussed in view of the practical engineering.
Liquefaction Resistance of Different Size/Shape Sand-Clay Mixtures Using a Pair of Bender Element–Mounted Molds
Authors: Cabalar A. F. , Demir S. , Khalaf M. M. 
Published: May 2019

Abstract
The aim of this study is to assess the influences of both the size and shape of sand grains mixed with a clay on shear modulus (Gmax)– and shear wave velocity (vs)–based liquefaction resistance (cyclic resistance ratio, CRR) using an intensive series of bender element (BE) tests. A low plasticity clay (CL) was added to two specific particle gradations (0.15–0.30 mm, and 1.0–2.0 mm) of clean sands with particular shapes (angular and rounded) at the percentages of 5, 10, 15, 20, 30, and 40, by dry weight. The BE tests were performed on the remolded specimens of different size/shape sands containing various amounts of CL in a recently designed mold used specifically for cohesionless soils, and then the values of vs, Gmax, and CRR were investigated. In most of the cases, the testing results indicated that, up to 20 % fines, which is named as transition fines content (FCt), Gmax and CRR values decreased, and then they increased for the specimens tested. Eventually, Gmax and CRR values of the specimens were significantly changed by the physical features (size, shape) of the sand grains with all the clay inclusions and frequencies applied.
An Experimental Evaluation of Mechanical Properties and Microstructure Change on Thin-Film–Coated AISI-1020 Steel
Authors: Gupta G. , Tyagi R. K. 
Published: May 2019

Abstract
Low carbon steel AISI1020, which is a widely accepted material for industrial applications, was surface coated, and its role in enhancing endurance strength and other mechanical properties was investigated for improving performance. In this work, an experimental investigation on the effect of different types of coating processes on surface roughness, surface hardness, and endurance strength was conducted. Thin films were deposited over the surface of standard specimens by galvanizing, electroplating, and spraying techniques. Chromium, zinc, nickel, and tin were used as the coating material. It was found that optimum surface roughness, hardness, and endurance strength exist for zinc coating compared with the others under investigation. The surface roughness, hardness, and endurance strength are associated by bonding strength and a chemical bond between parent metal and coated surface.
Argumentative Questions in an EFL Material: Fostering Students’ International Mobility
Authors: Richter Carla , Larré Julia , Damianovic Maria Cristina 
Published: May 2019

This paper aims at analyzing and categorizing the questions in an EFL teaching material[1](RICHTER, 2015), in accordance to the categories created by Ninin (2013). The material was designed for the subject “English for Computer Studies” at a federal university in the northeast of Brazil. We discuss how the questions used in the material provide learners with opportunities to become professionals that act argumentatively and revise their own points of view in the research they developed during the course and outside the classroom. The material, which was designed by the researcher, focuses on the participation of students in international academic events. Grounded in the lineage of Socio-Cultural-Historic Activity Theory (SCHAT) (VYGOTSKY, 1934/2007; LEONTIEV, 1977/1997; ENGESTRÖM, 1987/1999), this paper is based upon the Critical Collaborative Research (CCR) and is fundamentally rooted in Applied Linguistics (LA) for this is a study of language in the Academic realm that promotes changes in the social roles. Questions used in the teaching material (RICHTER, 2015) were analyzed according to categories such as: form, type, nature, thematic conduction and structure (NININ, 2013). Three versions of the same abstract written by students were also examined so as to check how the teaching material questions impacted on learners’ writing. Data analysis suggested that the type of questions may contribute to argumentation, to the exhibition of points of view, as well as to the dialogic expansion of knowledge in students’ writing. In addition to that, the choice of questions may encourage learners to take part in the dialectic organization of the text. (NININ, 2013).
Em busca da justiça cognitiva: leituras e leitoras para um processo de escolarização decolonial

Embora no plano legal, a escola como instituição e como lócus de transformação tenha podido se renovar por leis que, alterando a LDB (Lei de Diretrizes e Bases da Educação Brasileira de 1996) instituem a obrigatoriedade do ensino das histórias e culturas africanas e afro-brasileiras (Lei 10639 de 2003), bem como das histórias e culturas indígenas (Lei 11645 de 2008), pode-se afirmar que no plano das relações cotidianas, subjetivas e intersubjetivas, muito pouco ou quase nada se alterou na educação brasileira em termos efetivos: o acesso a posições e profissões consideradas “de maior prestígio” continua figurando como privilégio atrelado ao status de reconhecida branquitude. Tal situação torna-se ainda mais nefasta quando incide sobre o lugar e a condição dos modos e “fazeres” das mulheres negras intelectuais. Neste sentido, esse artigo pretende lançar luz sobre razões, consequências e possíveis encaminhamentos para se reverter tal quadro e promover uma ansiada descolonização epistemológica.
Complementary and alternative therapy (CAM) in haemophilia pain management: a review of published literature
Authors: Lambing Angela , Witkop Michelle , Humphries Thomas J. 
Published: May 2019

Abstract
Pain continues to be a significant issue for people with haemophilia (PWH), whether it is acute pain from a joint bleed, a needle stick when receiving clotting factor treatment, or chronic pain from chronic synovitis and arthritic changes. In the US, there has been controversy and uncertainty regarding the use of oral medications and opioids for the management of chronic pain, including haemophilia pain. Both PWH and their clinicians have started to explore nonpharmacologic options for managing pain, with many PWH trying to limit their use of oral pain medication and using alternative methods. There is little research around the use of complementary and alternative medicine (CAM) for pain management in the haemophilia community. This paper aims to provide a comprehensive literature review of current English language research on the use of therapies that fall into four distinctive domains of CAM in PWH. English language articles were obtained via searches in Medline, Embase and CINAHL using the target search words “haemophilia” or “bleeding disorders” in combination with other search terms relating to CAM. All references were considered regardless of year. Twenty-three CAM articles that included PWH or other bleeding disorders were identified; ten were evidence based while the remainder provided case reports and descriptions of CAM use in PWH. This indicates that there is limited current research in the area of CAM use for pain management in PWH. Evidence of the benefit of CAM is seen in studies of its use to treat pain in other conditions and health-related circumstances. Additional evidenced-based CAM research is needed so that alternative pain management therapies can be utilised in a safe and beneficial manner in PWH.
Legal Theory: Between Dogmatic Heritage and the Language of New Analytics
Authors: Vedeneev Yu. A. 
Published: May 2019

The article is devoted to analyzing conceptual shifts in the description and explanation of the phenomenon of law. The subject of the science of law constitutes the category of changing mental, linguistic and conceptual forms of its existence and expression. The development of the science of law is subject to the cultural and historical logic of evolution both as a phenomenon of law and the language of reasoning regarding law. The evolution of the phenomenon of law and the evolution of the science of law take place in a complex and dynamic environment of institutional and conceptual changes and mutual influences. Legal reality as a social fact and the concept of the fact exists within the cultural and historical boundaries of the interaction between the language of legal practice and the language of legal theory.Understanding of legal reality as a linguistic reality (phenomenon) requires the development of mental models (epistems) that allow us to identify the most significant aspects of manifestations of legal reality in a variety of socio-cultural contexts of its linguistic — institutional (practical) and conceptual (theoretical) — expression. The current agenda covers the formation of the general body of the theory of jurisprudence per se, or jurisprudence of the judiciary. Its analytical basis forms theoretical history of the legal science presented in various cultural and historical forms and expressions of the legal knowledge.
