El modelo TPACK para enseñar, aprender y evaluar el concepto de movimiento
Authors: Morales Olga Lucia Godoy
Published: December 2019

El concepto de movimiento ha apasionado a filósofos y científicos por más de dos mil años. Sin embargo, a pesar de ser un tema fascinante para la humanidad porque permitió responder preguntas como: ¿por qué los objetos caen hacia la superficie de la tierra?, o ¿cómo se concluyó que la tierra gira alrededor del sol?, resulta para los estudiantes difícil de comprender y usar para explicar situaciones cotidianas. Para contribuir con la enseñanza, el aprendizaje y la evaluación (en adelante E-A-Ev) de este concepto, se asumen y desarrollan cinco premisas epistemológicas: 1) Los textos recogen una propuesta específica de E-A-Ev y el medio para conocerla es establecer su modelo pedagógico. 2) La historia y la epistemología aportan elementos para investigar, enseñar, aprender y evaluar el concepto de movimiento. 3) El profesor construye su propio modelo pedagógico a partir de la interpretación que realiza de él y de cómo concibe la E-A-Ev. 4) Las ideas iniciales de los estudiantes median su E-A-Ev, y 5) La tecnología de los recursos digitales provee nuevos modelos para su E-A-Ev. El principal resultado es que se requiere la generación de propuestas educativas que incluyan las ideas iniciales de los estudiantes, a la vez que los ayuden a relacionar los conceptos físicos con el formalismo matemático y a utilizar la tecnología más allá de la realización de experimentos. Una conclusión que se deriva de la investigación es que el TPACK es un modelo integrador que articula las premisas epistemológicas y facilita la incorporación de los conocimientos de contenido, pedagógicos y tecnológicos contribuyendo con la E-A-Ev de este concepto.
TRATAMENTO DE EFLUENTE DE PROCESSOS DE RADIOGRAFIA: SOLUÇÃO PARA DESCARTE DOS RESÍDUOS
Authors: Nascimento Junior Ailton Venâncio , Santos Thaísa Cristiane Assis , Gonçalves Erika Peterson , Barbosa Monica Duarte Vieira Del Core Torres
Published: December 2019

O processo da revelação das imagens de radiografias simples utilizadas como diagnóstico por imagem na área da saúde consiste em quatro etapas: revelação, fixação, enxágue e secagem. Esses processos geram resíduos que quando descartados de forma inadequada, poluem o meio ambiente, devido a altas concentrações de elementos compostos por sulfetos e derivados da prata. De acordo com a Resolução nº 358/05 do Conselho Nacional do Meio Ambiente (CONAMA), os efluentes gerados pelo processamento das radiografias se encaixam no grupo B (resíduos químicos), pois contém substâncias tóxicas que causam risco ao meio ambiente e para a saúde da população. Um dos possíveis métodos para o tratamento desse efluente é a eletrocoagulação. É um método relativamente barato, onde a partir de uma eletrólise, pode-se ocorrer a desestabilização e agregação de partículas, onde há a formação de precipitado. A metodologia consiste em tratar o efluente gerado no processo de diagnóstico por radiografia simples pelo método da eletrocoagulação, e assim poder comparar os resultados de turbidez, dureza do líquido, análise da demanda química de oxigênio (DQO) das amostras tratadas e assim, atender todas as legislações ambientais de descarte. Os resultados consistem na queda de turbidez, queda de dureza, diminuição da DQO e nos sólidos totais, comprovando a eficiência do método de eletrocoagulação.Palavras-chave: DQO. Efluente. Prata. Radiografia. Tratamento.ABSTRACTThe process of revealing simple X-ray images used as diagnostic imaging in the health area consists of four stages: development, fixation, rinsing and drying. These processes generate waste that, when discarded improperly, pollute the environment due to high concentrations of elements composed of sulphides and silver derivatives. According to Resolution No. 358/05 of the Conselho Nacional do Meio Ambiente (CONAMA), the effluents generated by the processing of radiographs are classified as group B (chemical residues) because it contains toxic substances that cause a risk to the environment and to health of the population. One of the possible methods for treating this effluent is electrocoagulation. It is a relatively inexpensive method where, from an electrolysis, destabilization and aggregation of particles can occur, where there is precipitate formation. The methodology is to treat the effluent generated in the diagnostic process by simple radiography by the electrocoagulation method, and thus to compare the results of turbidity, liquid hardness, chemical oxygen demand (COD) analysis of the treated samples and thus, disposal legislation. The results consist of turbidity drop, hardness drop, COD reduction and total solids, proving the efficiency of the electrocoagulation method.Keywords: COD. Effluent. Silver. X-Ray. Treatment.

Published: December 2019

Apesar dos avanços alcançados na saúde bucal do Brasil, ainda existe necessidade de melhora na qualidade dos serviços prestados. O planejamento estratégico pode ser entendido como uma ferramenta gerencial perfeitamente aplicável à promoção de saúde bucal, em organizações públicas ou privadas. O presente trabalho teve como objetivo descrever a importância da utilização de um planejamento estratégico em saúde pública com foco na saúde bucal, portanto trata-se de uma revisão de literatura narrativa cuja coleta dos dados foi realizada através de consultas em livros, manuais e artigos científicos publicados em periódicos especializados, nas bases de dados científicas SCIELO, Google Scholar, e no portal de periódicos CAPES. O período de abrangência das buscas se estende dos anos 2006 a 2019, essencialmente, ainda que tenham sido incluídos alguns artigos relevantes de anos anteriores. Nas bases de dados, a busca foi realizada através dos descritores: saúde bucal, planejamento em saúde, planejamento estratégico, saúde pública. Pode-se concluir que o planejamento estratégico é uma ferramenta alternativa de suma importância para valorizar os pontos fortes e identificar os pontos fracos em uma organização, permitindo a elaboração de metas e a intervenção na realidade local de forma única e contínua, contribuindo para a otimização das atividades e o desenvolvimento da organização. Contudo, pode apresentar desvantagens como algumas ações que são elaboradas de forma centralizada e pouco participativa e sua utilização sem o conhecimento da realidade local ou embasada em uma demanda não programada.

Este estudo fornece uma avaliação das informações jornalísticas com base em indicadores interculturais e nos códigos de ética dos meios de comunicação. Para isso, analisamos a cobertura da mídia do caso denominado "anjo loiro" oferecido pelos canais de televisão públicos europeus, BBC, France 2, RAI 1 y TVE 1, no período entre 18 e 24 de outubro de 2013. Centra-se na aparência de uma garota em um acampamento cigano na Grécia, considerado um caso suspeito de tráfico de crianças ou sequestro. Aplicando uma série de indicadores que mostram distorções na representação, verifica-se que a informação se afasta dos padrões de qualidade interculturais e como um alerta internacional baseado na aparência física contribui para a estigmatização dos ciganos e a "etnificação" do crime.

Published: December 2019

O objetivo deste trabalho é examinar a atuação dos juízes de direito em Pernambuco entre os anos de 1835, quando foi estabelecido o decreto de serviço dos africanos livres e que foi mediado inicialmente pelos magistrados, até o fim do período da Conciliação, em 1857. O mapeamento de atuação desses operadores do Direito, além das diversas funções exercidas entre os cargos de Justiça e Polícia serão analisados neste artigo. Através do método prosopográfico, usamos da análise documental, como os códices de juízes municipais e de direito no Arquivo Público Estadual Jordão Emerenciano, APEJE, o Arquivo da Faculdade de Direito do Recife, além de alguns periódicos lançados na época, como fontes para compreender em quais locais esses magistrados mais atuavam. Com isso pretendemos também investigar os espaços de maior atividade da Justiça na província. Além disso, a identificação de personagens poucos discutidos na historiografia ajudam a desvendar quem de fato estava à frente das operações jurídicas na província. O questionamento desses atores sociais e sua efetividade na área do Direito e os entraves que ocorriam por conta de interesses particulares e/ou políticos estão inseridos no nosso campo de análise.

What Changes on the Inverse Catalyst? Insight From CO Oxidation on Au-Supported Ceria Nanoparticles Using Ab Initio Molecular Dynamics
Authors: Li Yong , Li Shikun , Bäumer Marcus , Moskaleva Lyudmila V.
Published: December 2019

Oxidation reactions catalyzed by Au nanoparticles supported on reducible oxides have been widely studied both experimentally and theoretically, whereas inverse catalysts, in which oxide nanoparticles are supported on metal surfaces, received considerably less attention. In both systems catalytic activity at metal – oxide interfaces can arise not only from each material contributing its functionality, but also from their interactions creating properties beyond the sum of individual components. Inverse catalysts may retain the synergy between the metal and oxide functionalities, while offering further specific advantages, e.g. a possibility to have better control over interfacial sites or to yield improved stability, activity, and selectivity. Our work provides the mechanism of O atom/vacancy diffusion-assisted Mars-van-Krevelen CO oxidation on gold-supported ceria nanoparticle through state-of-the-art ab initio molecular dynamic simulation studies.

Reaction Mechanism of the Metal Precursor Pulse in Atomic Layer Deposition of Ruthenium and Cobalt and the Role of Surface Facet NH/NH2 Coverage
Authors: Liu Ji , Nolan Michael
Published: December 2019

Ruthenium and Cobalt are potential candidate in replacing copper for interconnects and have been applied in the trenches and vias in semiconductor industry. A non-oxidizing reactant is required in atomic layer deposition (ALD) of thin films of these metals to avoid O-contamination. ALD of Ru and Co has been demonstrated experimentally, but the growth mechanism and key reactions are not clear. In this paper, the reaction mechanism of metal cyclopentadienyl (Cp, C5H5) precursors (RuCp2 and CoCp2) and NHx-terminated metal surfaces (Ru and Co) is studied by density functional theory (DFT) calculations. The Cp ligands are eliminated by CpH formation via a hydrogen transfer step and may desorb from metal surface. The nature of the NHx-termination plays an important role in the reaction energies and barriers as does the surface facet on Ru and Co, with (001) and (100) surfaces showing different reaction energetics. The results show that on the NHx-terminated surfaces corresponding to ALD operating condition (temperature range 550K to 650K), the two Cp ligands can be eliminated completely on both Ru and Co (100) surface during the metal precursor pulse, resulting in Ru or Co atom deposited on the (100) surface. But the second Cp ligand reaction of hydrogen transfer is thermodynamically unfavourable on the (001) surface, resulting in RuCp or CoCp fragment termination on (001) surface, along with the possibility of surface boned CpH. CoCp2 always has lower reaction barriers than RuCp2, regardless of surface facets or NHx coverage. These final structures after metal precursor pulse are essential to model the reaction during the following N-plasma step.
Reactions of an Aluminium(I) Reagent with 1,2-, 1,3- and 1,5-Dienes: Dearomatisation, Reversibility, and a Pericyclic Mechanism
Authors: Bakewell Clare , Garçon Martí , Kong Richard Y , O'Hare Louisa , White Andrew J. P. , Crimmin Mark
Published: December 2019

The reactions of an aluminium(I) reagent with a series of 1,2-, 1,3- and 1,5-dienes are reported. In the case of 1,3-dienes the reaction occurs by a pericyclic reaction mechanism, specifically a cheletropic cycloaddition, to form aluminocyclopentene containing products. This mechanism has been interrogated by stereochemical experiments and DFT calculations. The stereochemical experiments show that the (4+1) cycloaddition follows a suprafacial topology, while calculations support a concerted albeit asynchronous pathway in which the transition state demonstrates aromatic character. Remarkably, the substrate scope of the (4+1) cycloaddition includes dienes that are either in part, or entirely, contained within aromatic rings. In these cases, reactions occur with dearomatisation of the substrate and can be reversible. In the case of 1,2- or 1,5-dienes complementary reactivity is observed; the orthogonal nature of the C=C π-bonds (1,2-diene) and the homoconjugated system (1,5-diene) both disfavour a (4+1) cycloaddition. Rather, reaction pathways are determined by an initial (2+1) cycloaddition to form an aluminocyclopropane intermediate which can in turn undergo insertion of a further C=C π-bond leading to complex organometallic products that incorporate fused hydrocarbon rings.

Published: December 2019

The expansion of the genetic alphabet with additional, unnatural base pairs (UBPs) is an important and long standing goal in synthetic biology. Nucleotides acting as ligands for the coordination of metal cations have advanced as promising candidates for such an expansion of the genetic alphabet. However,the inclusion of artificial metal base pairs in nucleic acids mainly relies on solid-phase synthesis approaches and very little is known on polymerase-mediated synthesis. Herein, we report on the selective and high yielding enzymatic construction of a silver-mediated base pair as well as a two-step protocol for the synthesis of DNA duplexes containing a metal UBP. Guided by DFT calculations, we also shed light into the mechanism of formation of this UBP as well as into the structural and energetic preferences. Even though this silver UBP is not directly amenable to in vitro selection experiments, the enzymatic synthesis of this UBP provides valuable insights for the design of future, more potent systems aiming at expanding the genetic alphabet.
Effective Hamiltonians Derived from Equation-of-Motion Coupled-Cluster Wave-Functions: Theory and Application to the Hubbard and Heisenberg Hamiltonians
Authors: Pokhilko Pavel , Krylov Anna I.
Published: December 2019

Effective Hamiltonians, which are commonly used for fitting experimental observables, provide a coarse-grained representation of exact many-electron states obtained in quantum chemistry calculations; however, the mapping between the two is not trivial. In this contribution, we apply Bloch’s formalism to equation-of-motion coupled-cluster (EOM-CC) wave functions to rigorously derive effective Hamiltonians in the Bloch’s and des Cloizeaux’s forms. We report the key equations and illustrate the theory by examples of systems with electronic states of covalent and ionic characters. We show that the Hubbard and Heisenberg Hamiltonians are extracted directly from the so-obtained effective Hamiltonians. By making quantitative connections between many-body states and simple models, the approach also facilitates the analysis of the correlated wave functions. Artifacts affecting the quality of electronic structure calculations such as spin contamination are also discussed.
Oxidative Generation of Boron-Centered Radicals in Carboranes
Authors: Mills Harrison A. , Martin Joshua , Rheingold Arnold L. , Spokoyny Alexander
Published: December 2019

We report the first indirect observation and use of boron vertex-centered carboranyl radicals generated by the oxidation of modified carboranyl precursors. These radical intermediates are formed by the direct oxidation of a B−B bond between a boron cluster cage and an exopolyhedral boron-based substituent (e.g., −BF3K, −B(OH)2). The in situ generated radical species are shown to be competent substrates in reactions with oxygen-based radicals, dichalcogenides, and N-heterocycles, yielding the corresponding substituted carboranes containing B−O, B−S, B−Se, B−Te, and B−C bonds. Remarkably, this chemistry tolerates various electronic environments, providing access to facile substitution chemistry at both electron-rich and electron-poor B−H vertices in carboranes.
A kriptovaluták kihívásai a büntető anyagi és eljárási jogban

Published: December 2019

A kriptovalutákkal való visszaélések tekintetében problémát okozhat a gyakorlatban, hogy az elkövetés tárgyát hogyan sorolhatjuk be jogi szempontból. Előrelépés, hogy az ötödik pénzmosás elleni irányelv meghatározta a virtuális fizetőeszközök fogalmát. Az Unióban felismerték, hogy a kriptovaluták használata és a különböző átváltó, valamint pénztárcaszolgáltatók szolgáltatásainak igénybevétele pénzmosási és terrorizmus finanszírozási kockázatot hordoz magában. A hazai szabályozás vizsgálata alapján megállapítható, hogy különösen a pénzmosás tényállása világít rá arra, hogy e deliktum elkövetési tárgyát, a bűncselekményből származó „dolog” fogalmát értelmező rendelkezés keretében ki kellene terjeszteni a kriptovalutákra is. A kapcsolódó tevékenységi köröket is szabályozni kell, mint például az átváltó-, befektetési és pénztárcaszolgáltatókét a pénzügyi vagy kiegészítő pénzügyi szolgáltatások keretében, amelyhez a háttérjogszabály módosítása szükséges. Ez azonban – hasonlóan a kriptovaluták jogi besorolásához – elsődlegesen nem a büntetőjog feladata.

Custos, insegurança jurídica e terceirização: percepção das empresas
Authors: Dias Glauco Braga , Cavalcante Luiz Ricardo Mattos Teixeira
Published: December 2019

Objetiva analisar os custos e a insegurança jurídica relacionados à terceirização no Brasil após a promulgação das Leis nº 13.429/2017 e nº 13.467/2017 (reforma trabalhista), que disciplinaram esse instituto no país. Em particular, analisam a percepção das empresas prestadoras de serviços à Caixa Econômica Federal (CEF). A análise fundamenta-se i) nas planilhas de composição de custos de 121 contratos de prestação de serviços mantidos pela CEF entre 2013 e 2018; e ii) em entrevistas semiestruturadas com gestores das empresas contratadas pela CEF. Demonstra-se que ainda não houve reduções de custos e de insegurança jurídica nos contratos analisados e que os reflexos das inovações legislativas devem ser verificados após a consolidação dos entendimentos jurisprudenciais sobre a terceirização (possivelmente a partir de 2020). Conclui-se, assim, que as inovações legislativas ocorridas em 2017 tenderão a favorecer a terceirização nas empresas no Brasil, porém de forma diferida.

When human behavior, which is mediated by many different variables, is taken into consideration in a special condition such as traffic, it requires to investigate not only the visible situations that concern the moment, but also the sub factors that cause the resulting behavior. When examining driver behavior, focusing only on cognitive processes can lead to a one-way evaluation of the behavior, which may lead us to ignore factors such as emotions, past experiences and personality. Therefore, driver behavior should be addressed by a comprehensive holistic approach in which emotions and cognitive factors are considered together. The aim of the study is to investigate the role of empathy in the relationship between the situations evoking anger in traffic and anger expressions of the drivers. In order to run the study, data were collected through Demographic information form, Driver Anger Scale (DAS), Driver Anger Expression Inventory (DAX) and Basic Empathy Scale (BES) among 975 participants who are over 18 years of age and active drivers in traffic. According to the results, it has been seen that as people's cognitive empathy levels increased, their adaptive/ constructive anger expressions were increased. Also, the forms of expression of anger, was found to be significantly different according to gender.
THE RELATIONSHIP BETWEEN AGGRESSIVE BEHAVIOUR AND NEGATIVE AUTOMATIC THOUGHTS IN UNIVERSITY STUDENTS: THE MEDIATOR ROLE OF HOPELESSNESS LEVEL
Authors: BERNA Lerzan Tuğdem
Published: December 2019

Violence is increasing day by day. In order to prevent these actions, the reasons underlying the violence of a person against another person should be investigated. In this study, it is aimed to examine the mediating role of hopelessness in the relationship between the negative automatic thoughts that are known and the tendency of aggression.

Automatic Thoughts are accepted as the most superficial cognitive level affecting our emotions and behaviors. According to Aaron Beck's cognitive model, negative automatic thoughts occur as a result of the life events which are activating schemas that are formed in our childhood. There are many studies in the literature that relate negative automatic thoughts with emotional regulation. Studies on the relationship between negative automatic thoughts and level of hopelessness are also found in the literature.

The aggression tendency is one of the explanations about the reason for the aggression that is caused by the inability to control and suppress emotions. In this context, aggression can be considered as a result of emotional dysregulation. Considering the fact that negative automatic thoughts convey our emotions and behaviors without conscious judgment, a relationship between aggressive tendency and negative automatic thoughts is expected. Here, the effect of the hopelessness, which is known to be related to automatic thoughts, on this relationship will be discussed.

In this study, ‘Negative Automatic Thoughts Scale’, ‘Buss-Perry Aggression Questionnaire’ and, ‘Beck Hopelessness Scale’ were applied to university students.

A total of 112 participants were included in the study. The results of 19 participants were substracted because of unanswered questions in the scales. The average age of the participants in the sample was 19.9. The participants consisted of Acıbadem Mehmet Ali Aydınlar University undergraduate and associate degree students. 28% of respondents state that they are constantly thinking that there is a need of change.  29% of the respondents say that “Sometimes I feel like a bomb ready to explode”.

It can be seen that there is a relationship between aggression and negative automatic thoughts. In this context, it is possible to focus on the effects of cognitive behavioral therapies on the aggressive tendency.
History in Higher Education Programs: Dialogue and Discourse
Authors: Schlegel Steven
Published: December 2019

Aim/Purpose: This paper encourages the reader to think about the role history, or foundations, plays in graduate programs in the field of higher education. In so doing it looks at the types of conversations scholars in other fields and disciplines have had concerning the value of teaching students to think historically in settings where history is not the primary mode of scholarship, before thinking critically about the conversation we have had as it concerns higher education graduate programs.

Background: In many ways higher education programs have a complicated relationship with history. In some ways it can be seen as a central pursuit and in other ways it can be seen as a marginal scholarly activity. These two conflicting paradigms of central and marginal reflect a lack of scholarly discussion on what the field wants and expects from history.

Methodology: This paper considers the scholarly discussion that has happened in three fields apart from higher education administration in an attempt to suggest ways that scholars in higher education programs might conceptualize the value and role that history should play in our graduate programs.

Contribution: This paper invites scholars to think about what they want and expect students to gain from coursework on the history of higher education in comparison to what other fields have seen as the major reasons for including similar coursework.

Findings: Despite a generalized commitment to teaching the foundations of higher education, the field has not been clear about what it expects students to gain from this type of coursework. Although it is easy to suggest that teaching foundations is important, there has been limited scholarly work that meaningfully grapples with questions about the value of foundations in higher education programs.

Recommendations for Practitioners: As practitioners and researchers, we need to better articulate what we think foundations brings to graduate students in higher education programs and we need to do so in a manner that creates a single coherent paradigm for students.

Recommendation for Researchers: (Included in Recommendations for Practitioners)
