O papel das redes de transformação no processo de inovação: estudos de caso sobre a descoberta e a comercialização da inovação

Innovation is widely recognized as important. In addition, in this context, innovation networks have gained importance in academic studies, since an organization alone, does not always have access to all necessary resources. Gobbo Junior and Olsson (2010) proposed a model of network innovation whereby the transformation networks would be the linking structures between exploration and exploitation networks. In this context, this paper presents two case studies of innovation networks, aiming to increase the understanding on transformation networks. The objective was to understand how they interconnect exploration and exploitation networks; the main actors present in this interface; and to evaluate whether these actors can act as agents, to accelerate the innovation process. It was possible to verify how the transformation networks interconnect exploration and exploitation, and identify the practices and their main actors.

A influência do anel na evolução ponderal após quatro anos da derivação gátrica em Y-de-Roux laparoscópica

Use of ring in Roux-en-Y gastric bypass is still a matter of controversy among bariatric surgeons. There is no consensus on its impact in relation to weight loss and weight maintenance in the long term. AIM: To evaluate the influence of the ring on the evolution of body weight over four years after bariatric surgery. METHODS: Retrospective analyzis of 143 women who underwent laparoscopic Roux-en-Y gastric bypass paired on the use or not use of Silastic® ring. Follow-up time was 48 months. Inclusion criteria were age over 18 years, primary bariatric operation and regular attendance at the clinic during the period of interest for research. The technique kept small gastric reservoir estimated in a volume of 30 ml. The food limb had in average 150 cm and the bile one 40 cm from the duodenojejunal angle. The group "ring" used Silastic® device with length of 6.5 cm, placed 2 cm from gastrojejunal anastomosis. The ring was closed for five polypropylene surgical thread sutures. In the morning after surgery the patients received isotonic fluids; on the second day salty liquid diet and were discharged on the third day. Semisolid diet started from the 20th day and solid on the 30th, with daily tablet of polivitamins. RESULTS: The weight loss was larger on the ring than without ring groups in all periods, respectively 10% and only 5% in the third postoperative year. The proportion of not having reached the 50% excess weight loss expectative was significantly higher in the group without ring than in the group with the ring (31% and 8% respectively in the fourth year). There was no difference between groups in delayed recovery of weight lost with the operation. CONCLUSIONS: The results were favorable to use the ring exclusively when it is analyzed only the weight loss.

Os experimentos de Griffith no ensino de Biologia: a transposição didática do conceito de transformação nos livros didáticos

Griffith's experiments regarding bacterial transformation Pneumococcus are regarded as essential when related to DNA/heredity recognition process. The aim of the current study is to assess the didac tic transposition of the concept of bacterial transformation since the Griffith's descriptions until its current approach on didactic books. We realized that the historical context and the relationship between bacterial transformation and DNA recognition as genetic material are poorly explored. The core of our paper is the historical approach of those exper iments. By considering the wide richness of the knowledge that is ranged on Griffith's experiments, we suggest a didactic transposition concerning bacterial transformation in the learning process, involving an integration of contents.

Educação: transformação ou reprodução

Among the various school functions in capitalist society there in the literature and common sense that the school would have a central role in correcting social inequalities produced by the capitalist mode of production. We see, in today's society, children and young people who moved by the desire to get out of where they are, usually on the outskirts, in a vulnerable situation, seek growth through the study; They see it as a way out to another reality with more opportunit ies and chances for improvement, both as regards their quality of life, and even want to change, change and influence their own reality or part of it, with the knowledge learned in school. On the other hand, there are theorists who maintain that the school reproduces the basic features of the social structure and the current system of power in society. Our goal is to discuss the transformative potential of education as opposed to its role of reproduction of social inequalities, through the essential role of the teacher, who has a high profile role when it comes to change. The teacher is one of the first professionals that we remember when we turn to the school and refer to the systematic teaching. But sometimes forms of education present in the school, afflicting much of children and young people and are characterized in order to favor certain classes and eventually stop the growth and development of those who do not meet the required standards. In this paper we intend to compare two lines of thought, alluding to pedagogical activities in class, the Paulo Freire, which brings the teacher's figure with a responsible actor for lead students to reflection of their practice; and Pierre Bourdieu, which considers the pedagogical practice as an act of imposition of values of the ruling class. The work will address the issue from literature

Alterações de parâmetros relacionados ao metabolismo ósseo em mulheres submetidas à derivação gástrica em Y de Roux

OBJETIVO: Avaliar o metabolismo ósseo e a densidade mineral óssea (DMO) em mulheres adultas pós-derivação gástrica em Y de Roux (DGYR). SUJEITOS E MÉTODOS: Estudo transversal com 48 mulheres submetidas a DGYR há três anos e 41 saudáveis. Dados obtidos: índice de massa corporal (IMC), atividade física, consumo alimentar e DMO da coluna lombar, colo e fêmur total. Dosagem de cálcio, fósforo, magnésio, albumina, fosfatase alcalina, telopeptídeo-C (CTX), paratormônio (PTH), 25-hidroxivitamina D (25OHD), osteocalcina e cálcio urinário. RESULTADOS: Maiores alterações no grupo DGYR observadas nos níveis de osteocalcina (p < 0,001), CTX (p < 0,001) e PTH (p < 0,001). Deficiência de 25OHD foi a mais frequente no grupo DGYR (p = 0,010). Deficiência/insuficiência de 25OHD associou-se com hiperparatiroidismo secundário (p = 0,025). Não houve diferença entre os grupos em relação à DMO. A ingestão de energia (p = 0,036) e proteína (p = 0,004) foi maior no grupo controle. CONCLUSÃO: Em mulheres pós-DGYR, encontraram-se alta frequência de deficiência de vitamina D, hiperparatireoidismo secundário e elevação nos marcadores de remodelação óssea, sem alteração na DMO quando comparado com o grupo controle não obeso.

Resultados da cirurgia bariátrica e metabólica: gastrectomia vertical versus gastroplastia vertical com derivação em Y-de-Roux. Ensaio clínico prospectivo

Objetivos: Avaliar a equivalência da operação gastrectomia vertical com anel (GVA), em relação à operação gastroplastia vertical com anel e derivação gástrica em Y-de-Roux (DGA), na indução de perda ponderal e modificação da composição corporal em obesas mórbidas. Verificar os impactos laboratoriais e clínicos da GVA sobre as principais doenças associadas à obesidade mórbida, e a ocorrência de complicações, em comparação à DGA. Métodos: Ensaio clínico prospectivo não-randomizado, incluindo 65 mulheres obesas mórbidas, distribuídas em dois grupos, GVA (n = 33) e DGA (n = 32). Operadas consecutivamente, pelo mesmo cirurgião, por via laparotômica. Os parâmetros avaliados foram antropométricos; composição corporal, por meio de bioimpedância elétrica; laboratoriais; efeitos sobre as doenças pré-existentes e complicações. Resultados: Ocorreu perda de peso expressiva (p = 0,0000), redução do índice de massa corporal - IMC (p = 0,0000) e cintura abdominal (p = 0,0000) em ambos grupos. O índice cintura/quadril diminuiu (p = 0,0000) após ambas intervenções. A perda do excesso de IMC foi de 86,05% ± 14,2 no grupo GVA e 85,91 ± 15,71 no grupo DGA. A variação da gordura corporal foi de -35,84% ± 8,66 no grupo GVA e de -37,64% ± 9,62 no grupo DGA. A redução dos níveis de triglicerídios (p = 0,0222) foi mais expressiva no grupo DGA. O grupo DGA atingiu os alvos terapêuticos para o colesterol-LDL com maior freqüência (p = 0,0005), que o grupo GVA. Intolerância à glicose, diabetes mellitus tipo 2, hipertensão arterial sistêmica, esteatose hepática e síndrome metabólica, foram controladas de forma semelhante entre as técnicas. Anemia foi mais prevalente no grupo DGA (p=0,0033) e a esofagite erosiva, no grupo GVA (p = 0,0032). Não houve diferença na formação de cálculos biliares entre os grupos. Conclusões: A GVA é tão efetiva quanto a DGA em induzir perda ponderal e modificação favorável da composição corporal. A GVA é menos efetiva no controle da dislipidemia, em relação à DGA. GVA acarreta anemia em menor freqüência e, esofagite erosiva de maneira mais freqüente, que a DGA. GVA não é mais segura que a DGA, mas deve ser considerada intervenção bariátrica efetiva como segunda opção.
