The new Directive on Contracts for the Supply of Digital Content and Digital Services – Scope of Application and Trader’s Obligation to Supply – Part 1
Authors: Sein Karin , Spindler Gerald
Published: August 2019

After more than 3 years of discussions and negotiations the new contract law package consisting of the directive on the contracts for the supply of digital content and digital services and the new consumer sales directive have been finally adopted. The initial object-based regulatory approach has been kept, whereas the object of the contract now also encompasses digital services. The contract typology is still left within the discretion of the Member States and also the innovative concept of data as counter-performance is kept in the final version. The article discusses the scope of the digital content directive, including the complicated regulation on ancillary digital services (‘goods with digital elements’) as well as the trader’s main obligation – the obligation to supply. Conformity criteria, including the updating obligation, consumer’s remedies, trader’s liability as well as his right to make modifications will be dealt with in the follow-up article to be published in the next issue.
Carrying the Choice Theory of Contracts Further: Transfers, Welfare, and the Size of the Community
Authors: Esposito Fabrizio
Published: August 2019

The Choice Theory of Contracts is an ambitious, concise, and largely successful contribution to contract theory. Choice Theory is a liberal theory of contract law, grounded in a rich notion of autonomy, which stresses the obligation of the legal system to enhance our autonomy by ensuring the multiplicity of contractual types within the spheres of family, employment, home, and commerce.This article mitigates three shortcomings in The Choice Theory of Contracts and tries to carry Choice Theory further. A first shortcoming of the book is that the critique of transfer theory fails to acknowledge its analytical value. Second, in Part II of the book, Dagan and Heller overlap two issues: what the goods of contract are, and the compatibility of Choice Theory with the key concepts used by mainstream contract theories. Finally, Dagan and Heller do not fully acknowledge that the value of our autonomy is related to our ability to choose well. These revisions are useful to channelling scholarly attention on the implementation of Choice Theory and to sharpening the conceptual tools needed to do so.To show the potential of Choice Theory, this article carries it further. First, the economic concept of consumer sovereignty extends the programme of autonomy-grounded economic theories of contracts. Second, the size of the communities in which contractual relationships are created helps understand how various doctrines and even entire branches of the law foster the autonomy-enhancing capacity of contracts.The article concludes with a series of suggestions for carrying Choice Theory even further.
Stability and Hopf bifurcation periodic orbits in delay coupled Lotka-Volterra ring system
Authors: Su Rina , Zhang Chunrui
Published: August 2019

In this paper, we consider a class of delay coupled Lotka-Volterra ring systems. Based on the symmetric bifurcation theory of delay differential equations and representation theory of standard dihedral groups, properties of phase locked periodic solutions are given. Moreover, the direction and the stability of the Hopf bifurcation periodic orbits are obtained by using normal form and center manifold theory. Finally, the research results are verified by numerical simulation.
Toxicity of arsenic on isolated human lymphocytes: The key role of cytokines and intracellular calcium enhancement in arsenic-induced cell death
Authors: Zarei Mohammad Hadi , Pourahmad Jalal , Nassireslami Ehsan
Published: August 2019

Arsenic (As) is a semi-metal which causes health problems in human, and immune system has been documented as one of the main target of arsenic toxicity. Apoptosis has a crucial role in regulation of immune system, but it can also have an important role in As immune suppression. So, we decided to assess the comprehensive mechanism of As cytotoxic effect on lymphocytes isolated from human blood. We determine the direct effect of arsenic on human lymphocytes which have a key role in immune system functionality. To evaluate the mechanism of arsenic toxicity on human lymphocytes, we use accelerated cytotoxicity mechanisms screening (ACMS) technique. Lymphocytes were isolated from blood of healthy persons using Ficoll-paque PLUS standard method. Following treatment of human lymphocytes with 0.05-50 μM of arsenic for 12 h, cell viability was measured. For determination of mechanistic parameters, isolated human lymphocytes incubated with 1/2IC5012h (7.5 μM), IC5012h (15 μM) and 2IC5012h (30 μM) for 2, 4 and 6 h. The results of this study demonstrate arsenic-associated apoptosis in human lymphocytes is mainly through enhancement of intracellular calcium which causes oxidative stress and following adverse effect on lymphocytes organelles (like mitochondria and lysosome). Involvement of cellular proteolysis, activation of caspase-3, lipid peroxidation and stimulation of cytokines (IL2, INF-gamma and TNF-alpha) production were also associated with arsenic induced lymphocyte toxicity.
Metal-induced energy transfer
Authors: Gregor Ingo , Chizhik Alexey , Karedla Narain , Enderlein Jörg
Published: August 2019

Since about a decade, metal-induced energy transfer (MIET) has become a tool to measure the distance of fluorophores to a metal-coated surface with nanometer accuracy. The energy transfer from a fluorescent molecule to surface plasmons within a metal film results in the acceleration of its radiative decay rate. This can be observed as a reduction of the molecule’s fluorescence lifetime which can be easily measured with standard microscopy equipment. The achievable distance resolution is in the nanometer range, over a total range of about 200 nm. The method is perfectly compatible with biological and even live cell samples. In this review, we will summarize the theoretical and technical details of the method and present the most important results that have been obtained using MIET. We will also show how the latest technical developments can contribute to improving MIET, and we sketch some interesting directions for its future applications in the life sciences.
Strategic technology management within global value systems
Authors: Kvedarienė Audronė
Published: August 2019

Contemporary the concept of global value system extensively elaborated by scientist and applied by practices in the fields of management, economics and politics. The aim of this article is to provide the theoretical background and evolution of the global value system methodological approach from the global strategy management perspective. The technologies are considered as the main source of added value. Therefore the main scholars of technologies strategic management are provided in the article, though in the global value system concept it is implied that the source of added value originates from the allocation of added value activities across borders. Recently scholars analyse various sources for the added value upgrading, though critics of global value chain concept emphasise that besides economic added value, social issues should be considered.
Understanding Improvements to Low-Temperature Rheology of Stiff Binders Modified with Epoxidized Plant–Derived Oil Materials through Analytical Chemistry

Published: August 2019

Through recent work at Iowa State University, great potential was seen from epoxidized plant oil materials, epoxidized benzyl soyate (EBS), and epoxidized methyl soyate (EMS) as fluxes/rejuvenators. This work found that improvement in low-temperature performance was greater than improvement in high-temperature performance for solvent de-asphalting (SDA) and residuum oil super critical extraction (ROSE) unit bottoms when using either EBS or EMS as compared to results from modified vacuum distillation tower bottoms with EBS and EMS. Based on these results, analytical chemistry was done using Fourier transformed infrared with attenuated total reflection and ion mobility mass spectrometry (IM-MS) equipment. Chemical analysis showed that there is indeed something in the SDA and ROSE binders that is interacting with both EBS and EMS, making them perform aggressively. The region of interest was identified from IM-MS to be between m/z 250 and m/z 400 for the SDA and ROSE binders, of which there were 35 common components where 29 of them had similar abundances in the SDA and ROSE binders.

Published: August 2019

Self-sensing materials are capable of sensing the occurring strains and damage states present within. Smart concrete pavement made with cement-based self-sensing materials could be used for in situ monitoring of both the structural integrity as well as traffic characteristics. This article studies the electrical resistivity and piezoresistivity of cement enriched with multiwall carbon nanotubes (CNTs) under cyclic loading. The effects of fatigue damage and environmental factors, such as temperature, water content, and freeze-thaw cycles, on the resistivity and piezoresistivity were investigated. The test results show that the resistivity increases with the number of fatigue loading cycles. On the other hand, the resistivity decreases as the water content increases. In contrast, the piezoresistivity increases first and then decreases. The temperature has a significant yet offsetting effect on the electrical resistivity as well as the piezoresistivity. As the temperature increases, the electrical resistivity decreases, whereas the piezoresistivity increases. The major cause of the change in electrical resistivity and piezoresistivity was the change of tunneling conduction under different conditions. Moreover, the freeze-thaw cycles induce damage to the CNT-cement composite material. Therefore, the data collected by self-sensing materials must be calibrated for the water content and temperature before interpretation.

Pectinases have been used for
many industrial applications since long time ago. The largest industrial
application of these enzymes is in fruit juice and wine production for the
extraction, filtration and clarification and for the maceration of fruits and vegetables.
They work by enzymatic breaking down of the cell wall.In this study it was
aimed to use the previously optimized shake flask media formulation in batch
mode 1 L scale serial bioreactor system and 5 L scale in order to investigate
the effects of substrate concentration and scale on PG activity and biomass
production. In conclusion it was observed that average PG activity (101.29
U/ml) obtained in 5L scale bioreactor experiments was higher than the maximum
PG activity (88.55 U/ml) at 40 g/L orange peel (OP) concentration obtained in
the 1 L scale substrate concentration experiment. Furthermore,PG activity
increased with an increase in substrate concentration except for 60 g/L orange
peel concentration.

De Novo Genome Assembly and Comparative Genomics of the Barley Leaf Rust Pathogen Puccinia hordei Identifies Candidates for Three Avirulence Genes
Authors: Chen Jiapeng , Wu Jingqin , Zhang Peng , Dong Chongmei , Upadhyaya Narayana M , Zhou Qian , Dodds Peter , Park Robert F
Published: August 2019

Puccinia hordei (Ph) is a damaging pathogen of barley throughout the world. Despite its importance, almost nothing is known about the genomics of this pathogen, and a reference genome is lacking. In this study, the first reference genome was assembled for an Australian isolate of Ph (“Ph560”) using long-read SMRT sequencing. A total of 838 contigs were assembled, with a total size of 207 Mbp. This included both haplotype collapsed and separated regions, consistent with an estimated haploid genome size of about 150Mbp. An annotation pipeline that combined RNA-Seq of Ph-infected host tissues and homology to proteins from four other Puccinia species predicted 25,543 gene models of which 1,450 genes were classified as encoding secreted proteins based on the prediction of a signal peptide and no transmembrane domain. Genome resequencing using short-read technology was conducted for four additional Australian strains, Ph612, Ph626, Ph608 and Ph584, which are considered to be simple mutational derivatives of Ph560 with added virulence to one or two of three barley leaf rust resistance genes (viz. Rph3, Rph13 and Rph19). To identify candidate genes for the corresponding avirulence genes AvrRph3, AvrRph13 and AvrRph19, genetic variation in predicted secreted protein genes between the strains was correlated to the virulence profiles of each, identifying 35, 29 and 46 candidates for AvrRph13, AvrRph3 and AvrRph19, respectively. The identification of these candidate genes provides a strong foundation for future efforts to isolate these three avirulence genes, investigate their biological properties, and develop new diagnostic tests for monitoring pathogen virulence.
Involvement of a G Protein Regulatory Circuit in Alternative Oxidase Production inNeurospora crassa

Published: August 2019

The Neurospora crassa nuclear aod-1 gene encodes an alternative oxidase that functions in mitochondria. The enzyme provides a branch from the standard electron transport chain by transferring electrons directly from ubiquinol to oxygen. In standard laboratory strains, aod-1 is transcribed at very low levels under normal growth conditions. However, if the standard electron transport chain is disrupted, aod-1 mRNA expression is induced and the AOD1 protein is produced. We previously identified a strain of N. crassa, that produces high levels of aod-1 transcript under non-inducing conditions. Here we have crossed this strain to a standard lab strain and determined the genomic sequences of the parents and several progeny. Analysis of the sequence data and the levels of aod-1 mRNA in uninduced cultures revealed that a frameshift mutation in the flbA gene results in the high uninduced expression of aod-1. The flbA gene encodes a regulator of G protein signaling that decreases the activity of the Gα subunit of heterotrimeric G proteins. Our data suggest that strains with a functional flbA gene prevent uninduced expression of aod-1 by inactivating a G protein signaling pathway, and that this pathway is activated in cells grown under conditions that induce aod-1. Induced cells with a deletion of the gene encoding the Gα protein still have a partial increase in aod-1 mRNA levels, suggesting a second pathway for inducing transcription of the gene in N. crassa. We also present evidence that a translational control mechanism prevents production of AOD1 protein in uninduced cultures.
CYSTICERCOSIS OF BREAST: A RARE PRESENTATION
Authors: Vijay Ramita*, Udawat Hema
Published: August 2019

Cysticercosis is a parasitic infection caused by Cysticercus cellulosae, the larval stage of Taenia Solium. It is present world-wide, but more prevalent in developing regions like South America, Africa, South-East Asia and Eastern Europe due to poor environmental sanitation. The common sites are skeletal muscle, subcutaneous tissue, brain and eye. Breast is an uncommon site and diagnosis is usually incidental. Only a few cases have been reported, so far. Several diagnostic tools such as radiologic imaging, serology and immunologic detection are being used but the gold standard  remains the demonstration of the parasitic larva by FNAC or histopathology.

Here , we report an unusual case of cysticercosis in breast that was diagnosed o by Fine needle aspiration cytology.

The objective of this study was to explore relationships between the neighborhood food environment and obesity in urban women living in São Leopoldo, Rio Grande do Sul State, Brazil. A cross-sectional survey was carried out. This study was conducted with 1,096 women. Structured interviews were conducted using a standard pre-tested questionnaire. Obesity was defined as body mass index (BMI) ≥ 30kg/m2. Circular buffers of 400m in radius were created based on the centroid of the women’s houses who participated, in the 45 census tracts inhabited by them. Neighborhood food establishments were identified through systematic survey of all streets in the study areas and geographical coordinates of shops were collected. Establishments were evaluated using the NEMS tool. The prevalence of obesity was 33% among the women participants. After adjusting for individual variables, supermarkets and healthy food establishments were positively associated with obesity, PR = 1.05 (95%CI: 1.01-1.10), PR = 1.02 (95%CI: 1.00-1.04), respectively, while mean buffer income was negatively associated, PR = 0.64 (95%CI: 0.49-0.83). Neighborhood food environment factors were associated with obesity even after controlled for individual variables, as socioeconomic variables, behavioral and food purchase.

ABSTRACT Background: The bariatric surgery may have negative repercussions on oral conditions. Aim: To evaluate the impact of oral health educational/preventive program developed with patients submitted to gastroplasties. Method: The sample consisted of 109 patients randomly allocated to two groups: intervention group (IG), where they participated in the oral health promotion program that include multiple educational-preventive approaches; control group (CG), where they received usual care from the bariatric clinic staff, without participation in the program. The oral conditions investigated in the pre-operative and postoperative periods of one month (1M) and six months (6M) were: dental caries, periodontal disease, tooth wear, dental plaque and salivary flow. Results: After bariatric surgery, patients in IG presented: fewer changes in enamel (6M: p=0.004), dentin (6M: p=0.005) and gingival bleeding (6M: p<0.0001), reduction in plaque index (1M, 6M: p<0.0001) and increased salivary flow (6M: p=0.039), when compared with CG. Incipient tooth wear was recorded in both groups (6M: p=0.713). Conclusion: There was a positive impact of the implemented program in the prevention of the main oral health problems in patients who underwent gastroplasties, contributing to their quality of life.

Abstract: The aim of this study was to evaluate the influence of soil use on the morphological diversity of springtails and to verify the relationship of these organisms with soil physical, chemical, and microbiological properties. Samples were collected in the Southern region of Santa Catarina, involving three municipalities: Orleans, Lauro Müller, and Siderópolis, in the land use systems (LUS) of native forest (NF), Eucalyptus plantation (EP), pasture (PA), integrated crop-livestock (ICL), and no-tillage (NT). Soil samples to determine edaphic properties and pitfall traps were collected in winter and summer, in the same areas. The collected springtails were counted and morphotyped and the data were analyzed through abundance, Shannon-Wiener diversity (H') and Margalef index, Simpson dominance index (D), Pielou evenness index (J), morphotype richness, and Principal Components Analysis (PCA). Springtails morphotypes were influenced by the management conditions of each system, especially the impact of LUS on these organisms depends on the intensity of the forest/agricultural practices used, including crop rotation and soil preparation.

COMPETITION POLICY EVALUATION THROUGH DAMAGE ESTIMATION IN FUEL RETAIL CARTEL IN LONDRINA, BRAZIL
Authors: Cuiabano Simone Maciel
Published: August 2019

ABSTRACT This paper estimates the fuel retailer cartel damages in the city of Londrina, Parana, part south of Brazil, using reduced and structural forms for supply and demand. Brazilian Competition Authority (CADE) documents help to characterize the ethanol and gasoline retailers involved in the collusion. The objective is to evaluate competition policy by comparing the amount of estimated damages with the amount of applied fines. This paper also adds an important result to gasoline substitution, as data shows ethanol is perceived as a perfect substitute and its price is inelastic. Results show an overcharge of 3.6% to 6.6% in the gasoline market and up to 12% in the ethanol market during collusion. Fines should consider the deterrence effect and, giving the low probability of detection, CADE’s applied fines seemed to be in line with this objective.

Resumo O objetivo deste artigo é analisar a organização do trabalho em estabelecimentos familiares, cujos membros têm diferentesrelações com a dendeicultura na vila Água Azul, Tomé-Açu, Pará, considerando o debate sobre os impactos desta atividade no trabalho familiar e a tendência para a realização de uma agricultura com mais culturas perenes. A pesquisa envolveutrês tipos de famílias: com contrato para a produção de dendê, com algum membro assalariado na dendeicultura ou sem nenhuma relação com esta atividade. As conclusões mostram que: i) a organização do trabalho depende do tamanho daterra, do ciclo de desenvolvimento do grupo doméstico e do sistema de produção; ii) há relação direta entre a produção de dendê e a dependência da contratação de mão de obra; iii) há predominância de homens no trabalho agrícola e demulheres em outras atividades. O trabalho nos estabelecimentos resulta de numerosos arranjos e tem sido ressignificado, com a secundarização de culturas alimentares onde se cultiva dendê e com maior diversificação nos estabelecimentosque não têm relação com a dendeicultura. Aumenta, assim, a diferenciação das famílias quanto aos sistemas de produção e aos arranjos para o trabalho.

Published: August 2019

Resumo Este trabalho apresenta os resultados do estudo arqueológico de dois conjuntos de estruturas subterrâneas relacionadas a grupos Jê meridionais, localizadas no alto curso do Arroio Cará, no território cultural da Coxilha Rica, situada no planalto dos Campos Gerais, em Santa Catarina, Sul do Brasil. A revisão dos dados cronológicos disponíveis para sítios Jê meridionais possibilitou identificar a maior concentração de datas entre 800 e 1.600 AD. Foram obtidas três novas datas em 14C para os sítios pesquisados: 680 +/- 30 anos 14C AP para o sítio SC.PQ.17 e 1.440 +/- 30 anos 14C AP e 350 +/- 30 14C anos AP para o sítio SC.PQ.18. A ocupação mais recente, do sítio arqueológico SC.PQ.18, pode estar relacionada ao grupo cartografado por Curt Nimuendajú, junto aos rios Canoas e Pelotas, como ‘Pinaré’.
Leishmanioses: sua configuração histórica no Brasil com ênfase na doença visceral nos anos 1930 a 1960

Published: August 2019

Resumo Casos pioneiros de leishmaniose cutânea e mucocutânea nas Américas foram descritos em São Paulo, em 1909; somente em 1934, um patologista do Serviço de Febre Amarela encontrou a leishmaniose visceral no Brasil. Processos históricos concernentes a essas formas ganharam mais vigor institucional nos anos 1930. Se a Comissão para o Estudo da Leishmaniose consolidou o conceito de leishmaniose tegumentar americana, a Comissão Encarregada do Estudo da Leishmaniose Visceral Americana, chefiada por Evandro Chagas, deu origem ao Instituto de Patologia Experimental do Norte (1936) e ao Serviço de Estudo das Grandes Endemias (1938). A leishmaniose visceral ganhou crescente relevância no Nordeste brasileiro, nos anos 1950. Medidas de controle dos vetores por Dicloro-Difenil-Tricloroetano (DDT) ocorreram a reboque da campanha contra a malária, direcionadas também a cães, sacrificados massivamente, e humanos, tratados com drogas antimoniais. Grandes empreendimentos no interior do Brasil após o golpe civil-militar de 1964 transformaram a leishmaniose cutânea e mucocutânea em um problema sério na Amazônia e em outras regiões. No Brasil e em outros países, todas as formas de leishmaniose supostamente sob controle reemergiram em zonas rurais e urbanas e em áreas consideradas livres desse complexo de doenças endemoepidêmicas, devido a mudanças ambientais, migrações humanas, crescimento urbano caótico e outros processos socioeconômicos.
Ecologia, doença e desenvolvimento na Amazônia dos anos 1950: Harald Sioli e a esquistossomose na Fordlândia
Authors: Silva André Felipe Cândido da , Sá Dominichi Miranda
Published: August 2019

Resumo O artigo trata dos estudos do biólogo alemão Harald Sioli sobre a esquistossomose na região de Fordlândia, às margens do rio Tapajós, no Pará, realizados no início dos anos 1950, quando integrou a equipe do Instituto Agronômico do Norte (IAN). O IAN foi criado em 1939, no bojo de uma série de iniciativas destinadas a promover o desenvolvimento de regiões brasileiras, tidas como ‘atrasadas’ e vistas como ‘vazios demográficos’, por meio da agricultura, do incentivo à migração, de obras de infraestrutura e de ações de planejamento econômico. Sioli abordou a esquistossomose a partir de uma perspectiva ecológica. Correlacionou sua incidência com fatores ambientais ligados à distribuição dos caramujos hospedeiros, a atividades humanas e aos padrões de ocupação da terra. Dessa forma, podemos filiá-lo à vertente ecológica de estudo das doenças infecciosas, mostrando que ela teve lugar no auge do otimismo sanitário e do ciclo ideológico do desenvolvimentismo.
As categorias da alienação e do fetichismo na teoria social marxiana
Authors: Duboc Jéssica Ribeiro , Duriguetto Maria Lúcia
Published: August 2019

Resumo O artigo objetiva analisar a teoria marxiana da alienação nos Manuscritos Econômicos-Filosóficos de 1844, Grundrisse e no Livro I d’O Capital. Partimos da premissa que a categoria da alienação adquire novas determinações na teoria social marxiana, que estão organicamente ligadas ao desenvolvimento do modo de produção capitalista e da consequente maturação da crítica da economia política realizada por Marx. Tais determinações se materializam no chamado fetichismo da mercadoria, a manifestação particular da alienação nos moldes da sociabilidade burguesa desenvolvida.
Marx e o Direito do trabalho: a luta de classes, o terreno jurídico e a revolução
Authors: Sartori Vitor
Published: August 2019

Resumo Neste artigo trataremos da relação de Marx com o emergente Direito do trabalho. Pretendemos mostrar que ao mesmo tempo em que Marx considera o terreno jurídico como um palco do conflito classista, ele traz à tona as limitações da esfera jurídica. Com isso, diz Marx ser essencial a luta pela diminuição da jornada de trabalho, bem como a busca pela regulamentação jurídica. No entanto, simultaneamente, enxerga tais lutas, na melhor das hipóteses, como parte da preparação do terreno revolucionário, em que, em verdade, segundo ele, trata-se de suprimir a sociedade capitalista, o Direito e a própria centralidade que a atividade produtiva adquire na vida dos homens da sociedade burguesa. Se Marx diz que a diminuição radical da jornada de trabalho é necessária, trata-se de algo que não seria possível por meio do Direito, mas pela transformação substantiva da produção.
Sociabilidade dos adolescentes em conflito com a lei de Uberlândia (MG) em 2017
Authors: Silveira Manuela Soares , Previtali Fabiane Santana
Published: August 2019

Resumo O presente estudo apresenta resultados parciais de pesquisa de mestrado, que tem por objetivo analisar a sociabilidade dos adolescentes em conflito com a lei no município de Uberlândia (MG) no ano de 2017, mais especificamente os adolescentes do sexo masculino que cumprem medida socioeducativa de internação no Centro Socioeducativo de Uberlândia (CSEUB). Buscou-se então compreender quais os sentidos atribuídos pelos sujeitos às suas experiências sociais. Optou-se pelo materialismo histórico e dialético como base teórico-metodológica. Nesse sentido, parte-se de um recorte na sociabilidade dos sujeitos, no que diz respeito ao trabalho. Empreenderam-se a pesquisa bibliográfica para um amplo levantamento dos autores e de suas respectivas produções científicas, e a pesquisa de campo com um estudo de caso no CSEUB. A análise buscou inserir os participantes da pesquisa em um contexto macrossocietário, no que diz respeito à reestruturação produtiva e às novas configurações do mundo do trabalho, possibilitando compreender que os adolescentes aqui pesquisados e seu grupo social têm suas sociabilidades configuradas pelo sociometabolismo do capital, de modo a contribuir na reprodução e manutenção dessa estrutura.

A metodologia do estudo é qualitativa por meio de entrevistas semiestruturadas. Os resultados apontam para a precarização do trabalho social no contexto de neoliberalização, com consequências de sobrecarga e de estresse no cotidiano das profissionais.
Trabajo Social y gestión. Oportunidad conflictuada
Authors: Valenzuela Raúl Octavio Hozven
Published: August 2019

Resumen El presente artículo se pregunta respecto a la construcción subjetiva que emerge en la conflictiva relación entre Trabajo Social y la gestión de políticas sociales. Con este fin se realiza un análisis de discurso conforme la perspectiva de los autores Potter y Wetherell, tomando como referencia entrevistas vinculadas a un proyecto de investigación disciplinar desarrollado entre los años 2016 y 2017. Los resultados que emergen en los textos dan cuenta de un discurso de emprendimiento en torno al Trabajo Social, que, después de la recuperación del rango universitario acaecida en Chile en 2005, tensiona las tradiciones de esta profesión ante los mandatos establecidos por el Nuevo Management Publico (NMP), forjando conflictos no solo a escala del trabajo, sino que también culturales.
The Teacher’s Role in Telecollaborative Language Learning: The Case of Institutional Integrated Teletandem
Authors: Cavalari Suzi M. S. , Aranha Solange
Published: August 2019

ABSTRACT Teletandeem is a model of telecollaboration in which pairs of speakers of different languages meet virtually and regularly in order to learn each other’s language. The purpose of this paper is to discuss the pedagogical implications of integrating teletandem into the foreign language syllabus, focusing on the professor’s dual role: teaching English in regular face-to-face lessons and mediating virtual autonomous and collaborative learning in teletandem. Learning diaries, produced by EFL students from a Language Teacher Education course, were collected during eight weeks of an institutional integrated teletandem project between a Brazilian and a British university. Our analysis focused on the teacher’s role in mediating foreign language learning both in the classroom and through the learning diaries. We present evidence on what the professor does so that teletandem practice can contribute to language learning in the classroom and, by the same token, how EFL lessons can aid in autonomous telecollaborative learning.
Mapping the fern Blechnum heringeri (Blechnaceae, Polypodiopsida): recording the geographical distribution, ecological preferences and reporting a new record in northeastern Brazil

ABSTRACT Blechnum heringeri Brade is an endemic species from Brazil previously considered vulnerable. Until recently, there was a very limited number of records for this species, all from the Cerrado Phytogeographical Domain in central Brazil. Subsequent studies have reported its occurrence in the rupestrian grasslands (campos rupestres) on the “cangas”, within the Amazonian Domain. Here we present the first record of B. heringeri for northeastern Brazil, from an enclave of cerrado vegetation in the middle of the Caatinga Domain (Ceará State). This new record significantly extends the distributional range of the species, about 1,000 km from the known records in the Amazon and Cerrado Phytogeographical Domains. We also show that the species is associated with open vegetation or the transition between open vegetation and riverine forests, being recorded in cerrado vegetation, riverine forests associated with the cerrado, cerrado enclaves in the Caatinga and Amazonian Domains, and Amazonic campos rupestres on “canga”.

Resumo Objetivo: apresentar e analisar uma intervenção realizada para a realocação de servidores públicos, ocasionada por processo de terceirização das atividades operacionais de um restaurante universitário de uma universidade pública brasileira. Métodos: estudo qualitativo descritivo. Foram realizadas análise documental e organizacional, entrevistas semiestruturadas e aplicação do Índice de Capacidade do Trabalho com 33 funcionários, em 2016. Resultados: o levantamento de informações referentes ao estado de saúde dos funcionários e a análise das exigências físicas das tarefas prescritas nos cargos a serem assumidos possibilitou a adequação da realocação para as novas funções de forma a não prejudicar os trabalhadores que já apresentavam restrições médicas e de garantir novas funções compatíveis com a capacidade laboral dos trabalhadores deslocados e dos que permaneceram na atividade original reestruturada. Conclusão: o estudo mostrou que, antes de fazer uma realocação, é importante analisar e compreender o trabalho realizado pelo indivíduo e envolver todos os atores implicados no processo de adaptação às novas funções.
