Análise do crescimento das empresas de base tecnológica no Brasil

Technology-Based Firms (TBFs) are companies with intensive innovation dynamics based on technical competences, and for which high growth rates are expected. Nevertheless, even in developed countries, the evidence suggests that significantly high growth rates are more the exception than the rule. In Brazil, most studies on TBFs focus on factors that limit their success, such as managerial experience and capital availability. Based on extensive field research and on a reliable enterprise growth rate indicator, this article aims to evaluate the expansion of those firms, analyzing its relation to key elements such as degree of consolidation, market insertion, and public policy support. We found a growth rate which, although widely varied amongst firms, was significant and was not directly related to the amount of public policy support.

Cristo si è fermato a Eboli, de Carlo Levi e Francesco Rosi: memórias da cor de olhos tristes

As a hybrid genre, the narrative of Carlo Levi is an objective account and subjective elaboration that are equalized in a literary form. Written between 1943 and 1944, the book evokes with an atmosphere of memoir the period of 1935 and 1936, the writer’s exile. The film based on the narration fragmentizes the daily life of the problematic region and highlights the truth aimed by the discourses composed in times of crises, reinforced by action and expression without provincialism and also without a compensating aristocratic pose. It is possible to see some incapacity of the film by Rosi, natural to a certain degree, to translate the synthesis of literary treatment and socio-historical reflection. For this reason it is necessary to read the adaptation as an attitude about the literary matter and the result of historical experience. The memoir character relies on the artifice that makes good use of the book’s opening, the author’s short monologue, its narrative frame. The presence of paintings materializes the questions about the absurd contained in them

Infância e imagem: concepções sobre imagens de crianças no Facebook

In this course conclusion work intends to initially trace a brief history of childhood, watching as their design has been changing over time until you get to today, then it will be contextualized childhood and his relationship with the image, ie as this is narrated from images and phrases linked to them shared daily on a social network of communication accessed around the world, Facebook. Seek to identify the way that these images have in childhood now, in view of the existence of a Aesthetics domination over people, in the philosophical sense of the word means that which affects the senses, so the images can be produced Aesthetic emotions: ways of being, acting and feeling. For this will be a collection of materials on this web site, and to give theoretical support to work a literature will also be held, using for the basement of research, the theories of thinkers Walter Benjamin, Foucault, Philippe Aries, René Schérer

Occluded Tunneled Venous Catheter in Hemodialysis Patients: Risk Factors and Efficacy of Alteplase

Thrombosis of tunneled central venous catheters (CVC) in hemodialysis (HD) patients is common and it can lead to the elimination of vascular sites. This study aimed to evaluate the incidence of thrombotic obstruction of tunneled CVC in HD patients and the efficacy of occlusion treatment with alteplase use, and identify factors associated with thrombotic occlusion. It was a prospective cohort study performed in two centers which evaluated the diagnosis and treatment of thrombotic occlusion of CVC in HD patients for 24 consecutive months. The catheter occlusion was defined as the difficulty infusing or withdrawing fluid from their paths. Alteplase dose was infused to fill the lumen of the occluded catheter and remained for 50 min. As there was no obstruction of the catheter, the procedure was repeated. Three hundred and thirty-nine CVC in 247 patients were evaluated and followed, totalling 67 244 CVC-days. One hundred fifty-seven patients had only one CVC, 88 patients had two CVC during the study, and two patients had three CVC. The median age was 58 (47–66) years, patients were predominantly men (54%), with diabetic nephropathy as the main cause of chronic kidney disease (44%), the internal jugular vein as the main site of implantation (82%), and duration of dialysis before CVC implantation of 119 (41.5 to 585.5) days. Eight hundred and fifteen occlusion episodes were diagnosed (12 episodes/1000 CVC-days), with primary success with alteplase in 596 episodes (77%) and secondary in 81 cases (10%). In 99 episodes (13%), success was not achieved after the second dose of alteplase. Two hundred and thirty CVC were removed during the study and the removal causes were arteriovenous fistula use in 88 patients (38.3%), infectious and mechanical complications in 89 (38.7%) and 21 (9.1%), respectively, and others (transplantation, transfer, or death) in 32 patients (13.9%). Adverse effects were also not observed. In the multivariate analysis, we identified the greatest number of days with CVC (OR = 1.02, CI = 1.01–1.04, P = 0.004), the presence of diabetes (OR = 1.560, CI = 1.351–1.894, P = 0.015), and exit site infection (ESI) (OR = 1.567 CI = 1347–1926, P = 0.023) as factors associated with obstruction. Thrombotic occlusion showed frequent mechanical complication in CVC of HD patients. We observed 12 episodes of obstruction per 1000 CVC-days, with a high success rate after alteplase use (87%). In the multivariate analysis, the time with CVC, the presence of diabetes, and ESI were identified as variables associated with thrombotic obstruction.

Relationship between sweet orange yield and intensity of Citrus Variegated Chlorosis

Citrus Variegated Chlorosis (CVC) is currently present in approximately 40% of citrus plants in Brazil and causes an annual loss of around 120 million US dollars to the Brazilian citrus industry. Despite the fact that CVC has been present in Brazil for over 20 years, a relationship between disease intensity and yield loss has not been established. In order to achieve this, an experiment was carried out in a randomized block design in a 3 x 2 factorial scheme with 10-year-old Natal sweet orange. The following treatments were applied: irrigation with 0, 50 or 100% of the evapotranspiration of the crop, combined with natural infection or artificial inoculation with Xylella fastidiosa, the causal agent of CVC. The experiment was evaluated during three seasons. A negative exponential model was fitted to the relationships between yield versus CVC severity and yield versus Area Under Disease Progress Curve (AUDPC). In addition, the relationship between yield versus CVC severity and canopy volume was fitted by a multivariate exponential model. The use of the AUDPC variable showed practical limitations when compared with the variable CVC severity. The parameter values in the relationship of yieldCVC severity were similar for all treatments unlike in the multivariate model. Consequently, the yieldCVC intensity relationship (with 432 data points) could be described by one single model: y = 114.07 exp(-0.017 x), where y is yield (symptomless fruit weight in kg) and x is disease severity (R2 = 0.45; P < 0.01).

Endophytic Methylobacterium extorquens expresses a heterologous beta-1,4-endoglucanase A (EglA) in Catharanthus roseus seedlings, a model host plant for Xylella fastidiosa

Based on the premise of symbiotic control, we genetically modified the citrus endophytic bacterium Methylobacterium extorquens, strain AR1.6/2, and evaluated its capacity to colonize a model plant and its interaction with Xylella fastidiosa, the causative agent of Citrus Variegated Chlorosis (CVC). AR1.6/2 was genetically transformed to express heterologous GFP (Green Fluorescent Protein) and an endoglucanase A (EglA), generating the strains ARGFP and AREglA, respectively. By fluorescence microscopy, it was shown that ARGFP was able to colonize xylem vessels of the Catharanthus roseus seedlings. Using scanning electron microscopy, it was observed that AREglA and X. fastidiosa may co-inhabit the C. roseus vessels. M. extorquens was observed in the xylem with the phytopathogen X. fastidiosa, and appeared to cause a decrease in biofilm formation. AREglA stimulated the production of resistance protein, catalase, in the inoculated plants. This paper reports the successful transformation of AR1.6/2 to generate two different strains with a different gene each, and also indicates that AREglA and X. fastidiosa could interact inside the host plant, suggesting a possible strategy for the symbiotic control of CVC disease. Our results provide an enhanced understanding of the M. extorquens-X. fastidiosa interaction, suggesting the application of AR1.6/2 as an agent of symbiotic control.

Estratégia internacional de uma multinacional emergente brasileira: o caso JBS

Este estudo preocupa-se em questionar se as teorias tradicionais de internacionalização são adequadas para explicar a expansão internacional das multinacionais de países emergentes. Procurando avançar nessa questão, investigam-se as estratégias de internacionalização adotadas pela JBS, multinacional brasileira do setor frigorífico. Os resultados evidenciam que a empresa adotou duas das cinco estratégias genéricas específicas ao contexto de países emergentes sugeridas por Ramamurti e Singh (2009): consolidador global e integrador vertical. Além disso, ao analisar a internacionalização da empresa em estudo, chama atenção a velocidade do processo, em comparação às multinacionais tradicionais. Conclui-se que o principal modo de entrada que possibilitou a expansão internacional foi a aquisição e que essa trouxe vantagens à empresa, como o acesso a recursos estratégicos, o crescimento rápido, a possível superação da liability of foreignness, a oportunidade para competir globalmente e a diversificação dos segmentos de atuação que geram sinergias às atividades da empresa.
