Analysis of susceptibility profile of Pseudomonas spp. and prevalence of bacterial samples from the surfaces of dental consulting-rooms

The aim of this research was to evaluate the susceptibility profile of Pseudomonas spp. and the prevalence of bacterial samples isolated from horizontal surfaces surrounding wash-basins used by dentists in several adjoined consulting-rooms, at points next to and at a distance from the basin, before and after surgical procedures. Our results showed a high percentage of Gram-positive cocci and Gram-negative bacilli; 34.66% were Staphylococcus spp. and 30.12% were non-fermentative Gram-negative bacilli among which Pseudomonas spp. (40.90%) was the commonest genus. Analysis of the susceptibility profile of Pseudomonas spp. isolates by determining the minimal inhibitory concentration (MIC) of 14 antibiotics showed a great variation among the strains and high rates of resistance to cefazolin, ceftazidime and aztreonan. Of the 14 antibiotics tested, 59.03% were found to be active against all the environmental isolates. Strains were resistant to aztreonan (62.82%), while susceptibility to third generation cephalosporins was variable.

Risk management in software projects through Knowledge Management techniques: Cases in Brazilian Incubated Technology-Based Firms

In businesses such as the software industry, which uses knowledge as a resource, activities are knowledge intensive, requiring constant adoption of new technologies and practices. Another feature of this environment is that the industry is particularly susceptible to failure; with this in mind, the objective of this research is to analyze the integration of Knowledge Management techniques into the activity of risk management as it applies to software development projects of micro and small Brazilian incubated technology-based firms. Research methods chosen were the Multiple Case Study. The main risk factor for managers and developers is that scope or goals are often unclear or misinterpreted. For risk management, firms have found that Knowledge Management techniques of conversion combination would be the most applicable for use; however, those most commonly used refer to the conversion mode as internalization.. © 2013 Elsevier Ltd.

Technological capacity-building in unstable settings: Manufacturing firms in Argentina and Brazil

From the 1970s onward, the macroeconomic context in Argentina and Brazil was characterized by drastic economic changes and instability. Numerous studies have documented the generally negative effect of this environment on the innovation capacities of the manufacturing sector. This paper, however, analyses the possible emergence of new innovation capacities in the period, bringing two important phenomena to light. First, a quite substantial number of firms, even in unstable settings, redoubled their innovation efforts. Second, these firms are mainly found in a small group of sectors associated with the countries’ static advantages or in sectors favoured by specific sectoral regimes. The findings, although exploratory, are a contribution to the debate on the development of innovative capacities in unstable macroeconomic contexts and the ability of sectors associated with the two countries’ static advantages to generate spaces of innovation and value creation.
