Os elementos de cocriação, especialmente aqueles defendidos pelo modelo DART (PRAHALAD e RAMASWAMY, 2004) têm sido sugeridos como variáveis que impactam diretamente na percepção de confiança. Este ...ensaio teórico, portanto, se propõem a analisar a relação entre ambos os conceitos, fazendo um recorte para o cenário de inovação disruptiva de serviço, especialmente voltado a empresas que atuam sob o escopo da chamada economia do compartilhamento. Ao cruzar os modelos teóricos conceituais, este trabalho propõe um quadro que relaciona os elementos de cocriação trabalhados nos pontos de encontro entre os atores, e como estes permitem a comunicação necessária para interferir em variáveis como reputação e reciprocidade, ambas fundamentais para o processo de confiança. Da mesma forma, mostra como a confiança e a pré-disposição para a cooperação e a cocriação podem ser relacionadas de forma cíclica.
The tomato crop is considered of great socio-economic importance in the world, being responsible for feeding millions of people daily. Still, the crop is considered strategic because its production ...is diverse in the world, being produced in a familiar way to large agroindustries, moving a rich productive chain. This work aimed to evaluate the production of tomato seedlings as function of different substrates, and to comprehend the character's interrelation through linear associations. The experimental design was randomized blocks, being one tomato cultivar, Santa Cruz Kada, disposed in 32 repetitions for each treatment. The treatments were established through the substrates carbonized rice husk, grape husk (S10), coconut fiber and commercial substrate (Bioplant), the experiment was carried out in a greenhouse using tubes. The characters measured 25 days after sowing were: Stem diameter, number of leaves, shoot length, root length, green mass of root, green mass of shoot, dry mass of shoot, and dry mass of root. Variance analysis was performed, and the characters that presented significance were compared by the Duncan test at 5% of probability. Subsequently, Pearson's linear correlation was individually performed for each substrate. Commercial and grape skin substrates were the most suitable for production of tomato seedlings cultivar Santa Cruz Kada. The characters stem diameter, number of leaves, shoot length, green mass of root and green mass of shoot revealed significant correlations; however they differently behaved in the substrates.

The co-creation elements, especially those advocated by the DART model (PRAHALAD and RAMASWAMY, 2004) have been identified as variables that impact directly on perception of trust. This theoretical ...essay, therefore, propose to analyze the relationship between both concepts, making a cut for the service disruptive innovation scenario, especially aimed at companies operating under the scope of the call sharing economy. When crossing the conceptual theoretical models, this paper proposes a framework that lists the co-creation elements worked in the meeting points between actors, and how they allow the necessary communication to interfere in variables such as reputation and reciprocity, both fundamental to the process of confidence. Also, it shows how trust and predisposition for cooperation and co-creation can be linked cyclically.
Background: The methods by which mathematics content can be taught and learned using technologies and how they condition the production of mathematical knowledge have usually been the subject of our ...research. These investigations have allowed us to describe, understand and analyse the educational context in which we researchers are inserted, also allowing us to highlight the teacher’s and the students’ actions, their categorisations, and connections during the implementation of classes. These reasons motivated us to carry out this investigation. Objectives: To characterise the teacher’s and the students’ actions, highlighting their connections. Design: Qualitative research based on content analysis. Setting and participants: The research subjects were 1 teacher; 24 elementary school students, 10 students of the 6th grade and 14 of the 7th grade, and 12 high-school 3rd graders, all enrolled in the Paraná state network. Data collection and analysis: The actions were captured through field notes and video recordings, later transcribed. Results: In view of the information collected and the analyses carried out, 22 categories were evidenced for the teacher’s action and 40 categories for the student’s action. Conclusions: We proved that some of the teacher's actions triggered several other students’ actions. However, we identified three categories of students’ actions unrelated to the teacher’s actions nor to the performance of the activity provided by the learning objects. In fact, such actions were provided by the learning environment in which students used technological resources.
Esta pesquisa apresenta um estudo sobre a formação de professores de matemática, analisando a produção bibliográfica em 15 anos da revista Zetetiké (1993-2007). Foram pesquisados 28 números (140 ...artigos), dos quais 49 foram classificados como de formação de professores, constituindo dessa forma o corpus da investigação. A pesquisa centrou-se em três unidades de registro e análise: (i) os problemas de pesquisa relacionados nos artigos; (ii) os sentidos de “ser professor” e seus “deveres”; e (iii) os sentidos da “formação do professor”. Para os processos de categorização, valemo-nos da Análise textual, o que nos possibilitou observar algumas tendências. Sobre os problemas de pesquisa, indicamos que as ações que mobilizam uma investigação vão desde relatar, divulgar, descrever, identificar até estudar, debater, compreender, avaliar. No que se refere ao “ser professor” e seus “deveres”, em todo o período pesquisado, foram apontados problemas relacionados ao conteúdo matemático e ao projeto pedagógico da unidade escolar, sendo que 30 dos 49 artigos destacam de maneira prescritiva como o professor “deve” agir em seu contexto educativo. Com relação aos sentidos sobre formação, as referências mais frequentes dizem respeito: às funções de uma formação; ao que se espera do professor durante e após o processo formativo; e à ênfase na importância da formação inicial para a formação do professor de matemática.
We present results of research aiming to identify and analyze the meanings of teacher education in papers published over 23 years of Bolema, from 1985 to 2007. Specifically, we analyzed what the ...authors of the articles understood as teacher education and how they approached it in their projects, research, and interventions. We found that teacher education is characterized: by means of the definition of teacher education, its objectives and functions; from what is expected of the teacher at the end of the education process; from the disciplinary and/or pedagogical contents proposed in courses; from the practical activities proposed; through suggestions of courses and their curricular structures; from reflections on its limitations and possibilities. Keywords: Journals. Bolema. Teacher Formation. Textual Analysis. Content Analysis.Apresentamos aqui resultados de uma investigação que teve por objetivo a análise dos artigos relacionados ao campo formação de professores em 23 anos de publicação do Bolema – 1985/2007. A finalidade da pesquisa foi identificar e analisar quais foram os sentidos sobre formação do professor elaborados nessas duas décadas, ou seja, o que os autores dos artigos compreendem por formação do professor e de que forma eles a propõem em seus projetos ou investigações ou intervenções. As análises realizadas nesses artigos nos mostraram que a formação de professores é caracterizada por meio: da definição de formação, de seus objetivos e funções; do que se espera do professor ao final do processo formativo; dos conteúdos matemáticos e/ou pedagógicos propostos; da proposição de atividades práticas; da sugestão de cursos e suas estruturas curriculares; da reflexão sobre seus limites e possibilidades. Palavras-chave: Revistas. Bolema. Formação de Professores. Análise Textual. Análise de Conteúdo.
