Resumo: Apesar da existência de anteriores estudos, tanto em termos nacionais como regionais, e que demonstram a forte presença de escravos em Évora nos séculos XV e XVI, localizar a população escrava na documentação de instituições religiosas femininas da cidade e entender a sua condição de vida nessas comunidades não se revela fácil. Muitas das referências à sua existência são indiretas, ao fazerem parte de um dote ou doação (constando como bens a que se atribui um determinado valor), que podia ser testamentária, de partilhas e sentenças. São também de difícil perceção as tarefas desempenhadas no quotidiano de espaços claustrais, especialmente os femininos, sujeitos às exigências pós-tridentinas. Só com a apresentação de alguns casos, a juntar aos já conhecidos, poderemos sugerir algumas considerações sobre esta matéria. Abstract: Despite the existence of previous studies, both national and regional, studies that demonstrate a strong presence of slaves in Évora in the 15th and 16th centuries, locating them in documents from the city’s female religious communities and understanding their living conditions in those communities is not an easy task. Many of the references to their existence are indirect and related to a dowry or donation (being mentioned as assets with an assigned value), which could be associated with a will, a partition or a sentence. It is also difficult to ascertain the tasks they performed in the everyday life of cloistered communities, particularly the female ones, subject to the post-Tridentine requirements. Only by presenting a series of cases, other than the ones that are already known, will we be able to suggest considerations on this matter.

The aim of the study is to assess which factors influence the policymaking decisions to financially support an innovative investment project. Based on the case study of the Portuguese Innovation Incentive System in the Alentejo region, we estimated an econometric model based on firms’ and application’ characteristics, controlling for macroeconomic environment. The results indicate that the selection process is more focused on the expected project impact than on firms’ past performance. Furthermore, we found that government preference for promoting employment and exportation are shown to be higher than the impact on firm productivity.

Many studies are documenting positive large-scale species– people correlations (Luck, 2007; Schuldt & Assmann, 2010). The issue is scale dependent: the local association of species richness and people is in many cases a negative one (Pautasso, 2007; Pecher et al., 2010). This biogeographical pattern is thus important for conservation. If species-rich regions are also densely populated, preserving biodiversity becomes more difficult, ceteris paribus, than if species-rich regions were sparsely populated. At the same time, positive, regional species–people correlations are an opportunity for the biodiversity education of the majority of the human population and underline the importance of conservation in human-modified landscapes (e.g. Sheil & Meijaard, 2010; Ward, 2010).

Solar radiation takes in today's world, an increasing importance. Different devices are used to carry out spectral and integrated measurements of solar radiation. Thus the sensors can be divided into the fallow types: Calorimetric, Thermomechanical, Thermoelectric and Photoelectric. The first three categories are based on components converting the radiation to temperature (or heat) and then into electrical quantity. On the other hand, the photoelectric sensors are based on semiconductor or optoelectronic elements that when irradiated change their impedance or generate a measurable electric signal. The response function of the sensor element depends not only on the intensity of the radiation but also on its wavelengths. The radiation sensors most widely used fit in the first categories, but thanks to the reduction in manufacturing costs and to the increased integration of electronic systems, the use of the photoelectric-type sensors became more interesting. In this work we present a study of the behavior of different optoelectronic sensor elements. It is intended to verify the static response of the elements to the incident radiation. We study the optoelectronic elements using mathematical models that best fit their response as a function of wavelength. As an input to the model, the solar radiation values are generated with a radiative transfer model. We present a modeling of the spectral response sensors of other types in order to compare the behavior of optoelectronic elements with other sensors currently in use.
