Implementing process methods in learning research:targeting emotional responses in collaborative learning

Abstract. Context and aim: While interacting with peers and teachers in a collaborative learning task, students experience socio-emotional challenges and display emotional responses. These responses have two major components: arousal and valence, which influence the learning process and its outcomes. The aim of the study was twofold: first, to explore how group members’ arousal levels vary across different phases of a collaborative learning task; and second, to investigate how case students’ emotional responses are distributed in the arousal-valence space across the phases of the collaborative task. Methods: Twelve 6th graders from a school of Finland participated in a collaborative task, in groups of three students. The task was to build an energy efficient house in three distinct phases: brainstorming, planning, and building. While performing the activity, students wore Empatica E4 wristbands to measure their electrodermal activity (EDA) and were video-recorded with 360° cameras. Arousal levels were calculated in peaks per min (ppm) and classified as low, middle, and high. Emotional valence was classified from video analysis into positive, neutral, and negative. Results: The ranges for arousal levels were established between 26 and 88 ppm. Only two students displayed the same arousal level across the three phases of the experiment. Three students displayed higher arousal at first and then fell in to lower levels. Four students had the opposite experience and three students did not display a pattern. As for the case students, the student leading a poorly collaborating group experienced oscillating levels of arousal, from middle to high, and displayed a mix of negative and positive valence most of the time. The student loafing around experienced all arousal levels and positive valence most of the time. Overall conclusions and relevance: The study allowed to establish measurement thresholds for arousal as a starting point for future studies in collaborative learning and the arousal-valence space provided a quantifiable picture to help teachers understand the importance of emotional responses in classroom during collaborative learning

Investimento estrangeiro direto e industrialização no Paraná

Orientador : Prof. Dr. Marcelo Luiz CuradoTese (doutorado) - Universidade Federal do Paraná, Setor de Ciencias Sociais Aplicadas, Programa de Pós-Graduação em Desenvolvimento Ecônomico. Defesa : 27/05/2015Inclui referências : f.149-157Resumo: O objetivo desta tese é identificar o principal ou os principais fatores decisivos que desencadearam a realização dos Investimentos Diretos Externos (IDE) no Paraná com foco na atividade industrial. Após revisão bibliográfica sobre o tema em relação ao Brasil percebe-se que os IDEs se fizeram presentes de forma mais significativa desde a década de 1870, não se verificando estudos ou pesquisas em relação aos IDEs nos estados. A presente tese se dá sob esse enfoque inédito estadual em relação ao Paraná. Nota-se os primeiros registros relevantes de IDE no estado somente no início do século XX, não se mantendo no tempo. Observa-se, contudo, a presença expressiva do IDE a partir de 1973, com a instalação de empresas de capital externo localizadas na Cidade Industrial de Curitiba.Em 1995 nota-se um novo fluxo IDE em direção à região metropolitana de Curitiba e posteriormente um processo de interiorização destes investimentos. Tem-se como hipótese central que os investimentos externos industriais no estado do Paraná desencadeados em 1973 e nos períodos seguintes tiveram como fator decisivo as políticas públicas municipais e estaduais, mediante a influência dos cenários econômicos nacional e internacional, inibindo ou potencializando os investimentos. Para confirmação da hipótese é pesquisado o cenário estadual, com enfoque nas políticas públicas de industrialização, além dos cenários nacional e internacional realizadosa partir de depesquisas em relatórios institucionais, artigos, livros, periódicos e trabalhos científicos. Verifica-se que a ocorrência do IDE no estado se dá pela conjugação dos três fatores: 1) cenário internacional favorável; 2) cenário nacional favoráveis; e 3) políticas públicas municipais e estaduais de incentivo ao investimento industrial. As políticas públicas estaduais se constituemno último fator para o desencadeamento dos IDEs no estado, confirmando assim a hipótese inicial. Palavras chaves: Investimento externo direto, políticas públicas, Paraná.Abstract: The objective of this thesis is to identify the main or the mains deciding factors that led to the realization of Foreign Direct Investment (FDI) in Paraná focused on industrial activity. After bibliographic review on the topic concerning to Brazil is perceived that the FDI have been made more significant gifts in since the 1870's and there were no studies or research regarding the IDEs in the states. This thesis takes place in this state unprecedented approach towards Paraná. The earliest relevant records about FDI in Paraná are noted only at the start of the 20th century, not being maintained over time. However, an expressive presence of FDI is observed starting from 1973, with the installation of foreign-funded enterprises located at Industrial City of Curitiba. In 1995 a new flow of FDI is noted towards Curitiba's metropolitan region and afterwards there is an internalization process of these investments. It has been a central hypothesis that industrial foreign investment in Paraná triggered in 1973 and the following periods were as decisive factor municipal and state public policies, by the influence of national and international economic scenarios, inhibiting or enhancing investments. To confirm the hypothesis is researching the state scenario, focusing on public industrialization policies, besides the national and international scene from research in institutional reports, articles, books, periodicals and scientific papers. It appears that the occurrence of FDI in the state is given by the combination of three factors: 1) favorable international scenario; 2) favorable national scene; and 3) state and local public policies to encourage industrial investment. The state public policies constitute the ultimate factor in triggering the IDE sin the state, thus confirming the initial hypothesis. Keywords: foreign direct investment, public policy, Paraná

INTERAÇÃO INTERINSTITUCIONAL: O CASO DO PROGRAMA DE DESENVOLVIMENTO DA EDUCAÇÃO (PDE) / UNIVERSIDADE FEDERAL DO PARANÁ (UFPR) E O DESENVOLVIMENTO REGIONAL

O Programa de Desenvolvimento da Educação (PDE) implementado pela UFPR, pela Secretaria de Estado da Educação do Paraná e pela Secretaria de Ciência, Tecnologia e Ensino Superior do Paraná, é um exemplo das interações necessárias para assegurar a efetividade e a sustentabilidade da extensão universitária. Objetiva oferecer subsídios para um trabalho de formação continuada com reflexão crítica sobre as práticas e de (re)construção permanente e coletiva das identidades profissionais. Metodologicamente, o PDE dá ênfase no aprofundamento teórico, na integração teórico-prática, na troca de experiências, na produção de materiais didáticos e na interlocução entre professores das escolas da rede de ensino estadual básico e da universidade. Esse modelo de formação continuada, que ocorre durante dois anos, proporciona ao professor retorno às atividades acadêmicas de sua área de formação inicial. O Programa é estruturado em três grandes eixos: atividades de integração teórico-práticas, atividades de aprofundamento teórico e atividades didático-pedagógicas com suporte tecnológico. Os principais resultados: três turmas formadas com projetos de intervenção na escola, já implantados em escolas do ensino básico localizadas em Curitiba, União da Vitória e municípios das Regiões Metropolitanas Norte e Sul de Curitiba, e do Litoral Norte e Sul do Paraná. Conclusão: A universidade apropriou-se de uma metodologia para a formação continuada, ampliou sua rede de aliança e pretende consolidar a relação Universidade com a Escola e facilitar o diálogo com os agentes educacionais da região

Assessment of macro-micro element accumulation capabilities of Elodea nuttallii under gradient redox statuses with elevated NH4-N concentrations

Aquatic plants often encounter various redox conditions in their natural environment. Elodea nuttallii (Planch.), a submerged aquatic macrophyte, has a flexile ability to use different nutrient sources from various environments. In the present study, Elodea nuttallii was subjected to various redox conditions (+400 mV to –180 mV) at both normal (2.5 ppm) and high (10 ppm) ammonium concentrations and evaluated for macro and micro element accumulation. A reduced environment was prepared by adding glucose to growth medium and nitrogen gas bubbling, while an oxic environment was executed by atmospheric air bubbling. Plants in oxygen-deprived conditions manifested heavy metal (HM) toxicity, such as reduction of biomass and photosynthetic pigments, excess generation of reactive oxygen species (ROS), lipid peroxidation and reduction of major macro elements. In reduced treatments, the bioaccumulation sequence for micro elements was Cu>Mn>Zn>Al>Cd>Fe>Pb at both normal and high NH4-N concentrations. The combined effect of low redox state and high ammonium concentration had a strong physiological impact on the submerged macrophyte. However, macro- and micronutrient accumulation was more significantly affected by reduced environment than by a high NH4-N concentratio

An efficient method for measuring dissolved VOSCs in wastewater using GC-SCD with static headspace technique

Volatile organic sulfur compounds (VOSCs) are important sources of unpleasant odor in wastewater systems. However, the study of VOSCs is usually hindered by their complicated measurement method and highly reactive nature. In this work, a static headspace method utilising gas chromatography (GC) with a sulfur chemiluminescence detector (SCD) was developed to quantitatively analyze VOSCs in wastewater matrices. The method has low detection limits and requires no pre-concentration treatment. Three typical VOSCs, namely methanethiol (MT), dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), were chosen as examples for this study. The calibration curves of all three compounds covering a wide range from 0.5 ppb to 500 ppb showed good linearity (R-2 > 0.999). The method detection limits (MDL) were 0.08, 0.12 and 0.21 ppb for MT, DMS and DMDS, respectively. The reproducibility (relative standard deviation) was approximately 2%. The recovery ratio of MT, DMS and DMDS in spiked wastewater samples were 83 +/- 4%, 103 +/- 4% and 102 +/- 3%, respectively. Sample preservation tests showed that VOSCs in wastewater samples could be preserved in vials without headspace under acidified conditions (pH similar to 1.1) for at least 24 h without significant changes

Anthropogenic contributions to global carbonyl sulfide, carbon disulfide and organosulfides fluxes

Previous studies of the global sulfur cycle have focused almost exclusively on oxidized species and just a few sulfides. This focus is expanded here to include a wider range of reduced sulfur compounds. Inorganic sulfides tend to be bound into sediments, and sulfates are present both in sediments and the oceans. Sulfur can adopt polymeric forms that include S-S bonds. This review examines the global anthropogenic sources of reduced sulfur, updating emission inventories and widening the consideration of industrial sources. It estimates the anthropogenic fluxes of key sulfides to the atmosphere (units Gg S a-1) as: carbonyl sulfide (total 591: mainly from pulp and pigment 171, atmospheric oxidation of carbon disulfide 162, biofuel and coal combustion, 133, natural 898 Gg S a-1), carbon disulfide (total 746: rayon 395, pigment 205, pulp 78, natural 330 Gg S a-1), methanethiol (total 2119: pulp 1680, manure 330, rayon and wastewater 102, natural 6473 Gg S a-1), dimethyl sulfide (total 2197: pulp 1462, manure 660 and rayon 36, natural 31 657 Gg S a-1), dimethyl disulfide (total 1103: manure 660, pulp 273; natural 1081 Gg S a-1). The study compares the magnitude of the natural sources: marine, vegetation and soils, volcanoes and rain water with the key anthropogenic sources: paper industry, rayon-cellulose manufacture, agriculture and pigment production. Industrial sources could be reduced by better pollution control, so their impact may lessen over time. Anthropogenic emissions dominate the global budget of carbon disulfide, and some aromatic compounds such as thiophene, with emissions of methanethiol and dimethyl disufide also relatively important. Furthermore, industries related to coal and bitumen are key sources of multi-ringed thiophenes, while food production and various wastes may account for the release of significant amounts of dimethyl disulfide and dimethyl trisulfide
