Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sul / In search of a distinctive chemical education, with meaning for social and productive life of young high school students, the present study investigates how the theme "pollution" may facilitate the construction of the teaching and learning process of redox reactions content of high school students under a STSE (Science-Technology-Society-Environment) approach. For this, firstly, we sought theoretical references about the conceptual part of redox reactions and the theme "pollution". Then, we conducted an analysis of papers published in the journal Chemistry at the New School , with the intention of investigating how the redox reactions have been explored, their different approaches and their impact on the teaching of chemistry. From this, we developed a proposal to approach the redox reactions in the classroom, which was assessed through interventions with the second year high school students from a public school of Santa Maria, RS. Interventions in the classroom were carried out in two steps, both based on the methodology of the three pedagogical moments. The first developed inorganic redox content associated with the pollution of soil, whereas the second involved some organic redox reactions through the water pollution, specifically the treatment of effluents. This is a qualitative research. To collect data, we use questionnaires and textual productions, they were analyzed according to the Discursive Textual Analysis. The results allowed us to conclude that the development of redox reactions associated with the theme "pollution" by a STSE perspective favored teaching and learning of chemistry, as we observe an improvement in the construction of students knowledge. / Na busca de um ensino de química diferenciado, com significado para vida social e produtiva de jovens estudantes do nível médio, a presente pesquisa investiga como a temática Poluição pode favorecer a construção do processo de ensino aprendizagem do conteúdo de reações redox para estudantes de nível médio sob um enfoque CTSA (Ciência-Tecnologia-Sociedade-Ambiente). Para isso, primeiramente, buscamos referenciais teóricos a respeito da parte conceitual das reações redox e a temática Poluição . Em seguida, realizamos uma análise dos artigos publicados na revista Química Nova na Escola, com a intenção de investigar como as reações redox estão sendo exploradas, suas diferentes abordagens e sua repercussão no ensino de Química. A partir disso, desenvolvemos uma proposta para abordar as reações redox em sala de aula, que foi avaliada através de intervenções realizadas com estudantes da segunda série do nível médio de um colégio estadual de Santa Maria, RS. As intervenções em sala de aula foram realizadas em duas etapas, ambas baseadas na metodologia dos Três Momentos Pedagógicos. A primeira desenvolveu o conteúdo inorgânico de oxirredução associado à poluição do solo, enquanto que a segunda envolveu algumas reações orgânicas de oxirredução através da poluição da água, especificamente o tratamento de efluentes. A pesquisa é de caráter predominantemente qualitativo. Para a coleta de dados, utilizamos de questionários e produções textuais, analisados de acordo com a Análise Textual Discursiva. Os resultados encontrados nos permitiram concluir que o desenvolvimento das reações redox associadas a temática Poluição por um perspectiva CTSA favoreceram o ensino e a aprendizagem de Química, visto que observamos um avanço na construção do conhecimento dos estudantes.

The activity of turmeric in Mara Rosa received assistance from public and private institutions since 1997, when the executive power of the municipality and the Association of Small Farmers in the region of Pastinho sought the Federal University of Goias to promote the development of the productive chain of turmeric in Goias. In 2004, after the creation of the Permanent Working Group for Local Production, created by the Federal Government, was established the Local Productive Arrangement (LPA) of turmeric in the municipality of Mara Rosa, made possible by the large number of producers of turmeric, in around 300, and the tradition of growing the crop in the region. The objective of this study is to understand the social, technological, economic and environmental changes occurred in LPA turmeric postinstitutional interventions. The theoretical studies were carried out previously directed to agribusiness turmeric authors Milhomem & Teixeira (1998), Marinozzi (2002) and Noronha (2003). The research was based on data collected directly from participants in the agribusiness of turmeric in the region. The survey found that the average yield per hectare had increased up to 50.0% and gross margin achieved by producers in the increased activity of turmeric. The study concludes that the interventions implemented and under implementation in the region have promoted the social, economic and technological producers of turmeric, with the need to adopt new practices in order to preserve the environment / O município de Mara Rosa está localizado no estado de Goiás e é conhecido como a capital brasileira do açafrão por ser o maior produtor da cultura em Goiás e no Brasil. A atividade do açafrão em Mara Rosa recebeu intervenções de instituições públicas e privadas a partir de 1997, quando o poder executivo do município e a Associação dos Pequenos Produtores Rurais da Região do Pastinho buscaram a Universidade Federal de Goiás a fim de promover o desenvolvimento da cadeia produtiva do açafrão em Goiás. Em 2004, após a criação do Grupo de Trabalho Permanente para Arranjos Produtivos Locais, criado pelo Governo Federal, foi implantado o Arranjo Produtivo Local (APL) de açafrão na região do município de Mara Rosa, possibilitado pelo grande número de produtores de açafrão, em torno de 300, e pela tradição da cultura na região. O objetivo do trabalho é conhecer as mudanças sociais, tecnológicas, econômicas e ambientais ocorridas no APL do açafrão pós-intervenções institucionais. A base teórica foram trabalhos anteriormente realizados dirigidos ao agronegócio do açafrão dos autores Milhomem & Teixeira (1998), Marinozzi (2002) e Noronha (2003). A pesquisa baseou-se em dados coletados diretamente junto aos participantes do agronegócio do açafrão na região. A pesquisa constatou que a produtividade média por hectare apresentou elevação acima de 50,0% e a margem bruta conseguida pelos produtores na atividade do açafrão aumentou. O trabalho concluiu que as intervenções executadas e em implantação na região têm promovido o desenvolvimento social, econômico e tecnológico dos produtores de açafrão, havendo a necessidade de adotar novas práticas com o intuito de preservar o meio ambiente.

We believe that teaching of science can form more critical citizens. Thus, teaching of science allows citizens a better interaction with the world. This research aimed to evaluate the teaching of scientific concepts about substance in the adult education. Thus, we plan and develop pedagogical interventions (PIs) with approach in relations Science-Technology-Society-Environment (STSE). We have studied the processes of conceptual appropriation by Conversation Analysis (CA) produced these PIs. Based by socio-historical and cultural foundations, we developed an action research. Results lead us notice that the teaching and the learning of chemical concepts with STSE approach performed in adult education seems to contribute to the concepts appropriation of constituent entities of matter. Besides, he explained the link between the work world (context that characterizes and defines the subject of the YAE) and the chemical science, a fact that promoted the relations teacher - student - knowledge-cientific. / A Educação de Jovens e Adultos (EJA) no sistema educacional do país, caracteriza-se como uma modalidade de ensino, amparada por lei e voltada para pessoas que não tiveram acesso, por algum motivo, ao ensino regular na idade apropriada de acordo ao que se instaurou na Constituição Federal de 1988.Defendemos que ensinar ciências pode formar cidadãos mais críticos.Assim, ensinar ciências permite ao cidadão uma melhor interação com o mundo.Essa investigação visou avaliar o ensino dos conceitos científicos sobre substância na EJA. Desta forma, planejamos e desenvolvemos intervenções pedagógicas (IPs) com abordagem nas relações Ciência-Tecnologia-Sociedade-Ambiente (CTSA). Estudamos os processos de apropriação conceitual por meio da Análise da Conversação (AC) produzido nestas IPs. Pautada em bases sócio-históricas e culturais desenvolvemos uma pesquisa-ação. Os resultados permitem inferir que o ensino-aprendizagem dos conceitos químicos com enfoque CTSA realizado na EJA parece colaborar para a apropriação dos conceitos das entidades constituintes da matéria. Além do que, explicitou o vínculo entre o mundo do trabalho (contexto que caracteriza e define o sujeito da EJA) e a ciência química, fato que promoveu as relações professor-aluno-conhecimento científico.

The growing industry of Information and Communication Technology requires higher computing capacity of data centers. The air conditioning in data centers is a key to assure a sustainable computing environment. However, the traditional cooling systems cost large environmental footprints especially on energy consumption and greenhouse gas emissions. As a result, a green innovation of data center cooling solutions is taking place. The telecommunication company Teliasonera is developing a high density data center cooling system - the “Green Room” and has been studying the environmental performance of this system using a Life Cycle approach. As an extension of the previous study, more aspects of the project i.e. the location of the data center, life span, alternative cooling solutions, energy recovery possibilities and uncertainty analysis is explored using Life Cycle Assessment (LCA) methodology. The comparison of locations of the Green Room indicates that the local temperature and electricity production sources are essential factors for the environmental performance of the Green Room. The analysis of the Green Room’s life span reveals that the utilization phase may not always cause the most significant impact during the whole life cycle of the Green Room. If the life span changes, the manufacture phase may predominate the life cycle of the Green Room. The comparative result of alternative cooling technologies addresses that utilizing “natural coolant” (e.g. geo cooling) is a key for sustainable cooling innovation as it could significantly reduce the environmental footprint of the cooling system. Besides, heating a single building (partly) by the waste heat generated from the Green Room could save 30% of cumulative energy input and could reduce more than half of the total environmental impact. Additionally, results uncertainties caused by the choice of different LCIA methods are discussed in the end of the study. / Teliasonera's Green Room concept

In the wake of a digitally transforming environment, public sector organizations are realizingthe necessity to adopt new ways of managing their operations. The changing expectations anddemands of citizens and stakeholders are triggering such organizations to develop their deliveryof services, as well as digitally transforming their internal processes. As the public sector valuesservice delivery and cost-effectiveness, cloud services have become an attractive option to transition to, due to their flexible and economical characteristics. This qualitative study examines two Swedish municipalities in their transition to cloud services, studying the reasons behind said transition, and how those affect their adoption. The Technology-Organization-Environment (TOE) framework was utilized to evaluate the factors affecting the two organizations’ transitions and adoptions of cloud services, showcasing a connection between the framework’s elements and the analyzed results. The findings show pressure coming from both external and internal sources, restrictions involving governmental regulations and lack ofavailability, as well as how they manage these challenges, by finding new ways to innovate and preparing their organizations for future transitions.

Data är idag en central resurs i många organisationer och mängden data ökar för varje år. Detta kan innebära att organisationer påverkas till att söka efter nya teknologier som kan ge dem möjligheter att fatta datadrivna beslut i större omfattning. Den teknologi som denna studie undersöker är Data Virtualization (DV) av den anledning att det finns ett tydligt forskningsgap gällande varför organisationer väljer att implementera DV. Studien använder TOE-ramverket med syftet att kartlägga vad som gör att organisationer tar beslut om att implementera DV. Studiens datainsamlingsmetod är semistrukturerade intervjuer där fyra respondenter från olika företag i Norden intervjuades. Empirin analyserades för att identifiera vilka faktorer som var betydande för implementeringen av DV. Resultatet visade att nordiska organisationers beslut att implementera DV påverkades av många faktorer som redan har fastställts av tidigare forskning. Dessa faktorer är: relativ fördel, testbarhet, roller och kompetens, stöd från ledning och externt stöd. Slutligen har även två nya faktorer identifierats som betydande för implementationen av DV, vilket var storlek och spridning av data samt i specifika fall omorganisering. / Data is today a central resource in many organizations and the amount of data increases every year. This could result in organizations being influenced to search for new technologies that can give them opportunities to make data-driven decisions on a larger scale. The technology that this study investigates is Data Virtualization (DV) since there is a clear research gap regarding why organizations choose to implement DV. The study uses the TOE framework with the purpose of mapping what makes organizations decide to implement DV. The study's data collection method is semi-structured interviews where four respondents from different companies in the Nordics were interviewed. The empirical data was analyzed to identify which factors were important for the implementation of DV. The result showed that the adoption decision of Nordic organizations is influenced by factors that have already been determined by previous research. These factors are: relative advantage, testability, roles and skills, top management support and external support. Finally, two new factors have also been identified as important for the implementation of DV: size and distribution of data and, in specific cases, reorganization.

The rapid changes in the global economy have imposed high pressure on small and medium-sized enterprises (SMEs) and their operations. Many SMEs have realized how important it is to integrate all units in the business by introducing Enterprise Resource Planning systems (ERP systems).    The adoption decision phase in ERP systems is an early phase and is often confused with implementation, which is a major cause of failure. This confusion can especially hit hard on small and medium-sized companies that may lack sufficient resources. The adoption decision phase can be particularly crucial in such case. The purpose of this study is to investigate which driving forces that influence the adoption decision phase of ERP systems within SMEs. The Technology-Organization-Environment (TOE) theoretical framework was used to create a theoretical foundation for finding drivers from previous research.   Semi-structured interviews were then conducted with six ERP consultants. Respondents' responses were analyzed thematically, and 12 themes were identified as driving forces. These could then be compared with previous research. The driving forces identified were management and decision makers, benefits and efficiency, functionality, regulations and security, competition and the future, industry type and complexity, education and competence, finance and resources, supplier and solutions, integration with existing systems, maintenance and support, and challenges and uncertainty. The driving forces that were identified but could not be linked to previous research were functionality, and challenges and uncertainty.   Keywords: Adoption decision, driving forces, Enterprise Resource Planning systems (ERP system), small and medium-sized enterprises (SME), Technology-Organization-Environment (TOE).

In an increasingly digitalized society, the cyber threats faced by banks have become more extensive and complex. At the same time, artificial intelligence has developed into a powerful and disruptive technology that can be used to strengthen cybersecurity and counter financial crime, among other things. The purpose of the study was to map how Swedish banks use AI to counteract cyber threats and financial crime, and what benefits and challenges this entails. The study is based on four qualitative interviews with bank officials specialized in cybersecurity or financial crime. The Technology-Organization-Environment framework is used to analyze the challenges and factors affecting the use of AI. The results show that AI models are used for several security purposes, such as preventing DDoS attacks, malware detection and identifying signs of financial crime. The main benefits of AI are the ability to analyze large amounts of data in real time and to identify patterns and anomalies that are difficult for the human eye to see. However, there are a number of challenges for Swedish banks in the adoption and use of AI related to regulation, ethics and competence.
