Reserva extrativista Acaú-Goiana: tragédia comum ou decisão coletiva?

In recent years we have observed, in Brazil, the expansion of democratic spaces, providing the use of participatory management strategies in common-pool areas. However, the existence of a co-management model does not guarantee its practice, neither that it will prevent the depletion of common features characterizing the tragedy proposed by Hardin. In this work we analysed the management of Acaú-Goiana RESEX which is located in the cities of Acaú (PB) and Goiana (PE), eight years after its legal creation. We evaluated how much the users of RESEX possess information (even if non formalized) regarding the common use of area and whether they exhibit collectivist values. We used as an interpretative tool the facilitators principles of common resource management (PGRC) identified by Elinor Ostrom and the questionnaire of human values proposed by Schwartz. The human values questionnaire was applied to 240 individuals, half beneficiary and the other half non-beneficiary, only the beneficiaries were submitted to the questionnaire of PGRC. Interviews were conducted in the period of May to September 2014. We tested three hypotheses: 1) The degree of dependence from RESEX resources will play an important role on indirect knowledge of the PGRC; 2) the inclusion of individuals in a communal area (RESEX) increases collectivists values; 3) higher collectivist value rates increases knowledge of PGRC. To this end, we defined levels of socio-economic dependence of RESEX resources, knowledge of PGRC and individual values. GLM statistic analysis of mean comparison and correlation were employed. Our results showed that the knowledge on six of the seven items analyzed in the basic principles (PGRC) is still low. The extended land area and the high number of users may be exerting a detrimental effect on the development of a co-management. Contrary to expected, it was not the dependency who influenced knowledge on the PGRC, but the time spent in contact with the RESEX. This indicates that direct contact with the environment, not the dependence of it, that raises awareness about PGRC. According to our hypothesis, individuals with collectivist values showed greater knowledge of PGRC and reduced hours of work within the RESEX, indicating a greater tendency of individuals refrain their use of the common resource. Individualistic values correlated with less knowledge of a PGRC. Among the beneficiaries, individuals with higher individualistic values had higher monthly income, while among non-beneficiaries there was no such correlation, demonstrating the economic advantages of individualism (free-riding) in situations of non-private use of resources. Our data emphasize the importance of guiding the main actors in the development of a co-participatory management in the direction of the basic principles, and to develop collectivist values among users of a common good can raise awareness of these principles.

Análise dos custos assistenciais de uma operadora de plano de saúde no Brasil

The relevance of rising healthcare costs is a main topic in complementary health companies in Brazil. In 2011, these expenses consumed more than 80% of the monthly health insurance in Brazil. Considering the administrative costs, it is observed that the companies operating in this market work, on average, at the threshold between profit and loss. This paper presents results after an investigation of the welfare costs of a health plan company in Brazil. It was based on the KDD process and explorative Data Mining. A diversity of results is presented, such as data summarization, providing compact descriptions of the data, revealing common features and intrinsic observations. Among the key findings was observed that a small portion of the population is responsible for the most demanding of resources devoted to health care

CrossMDA-SPL: uma abordagem para gerência de variabilidades dirigida por modelos e aspectos

This paper proposes a systematic approach to management of variability modelsdriven and aspects using the mechanisms of approaches Aspect-Oriented Software Development (AOSD) and Model-Driven Development (MDD). The main goal of the approach, named CrossMDA-SPL, is to improve the management(gerência), modularization and isolation ou separation of the variability of the LPSs of architecture in a high level of abstraction (model) at the design and implementing phases of development Software Product Lines (SPLs), exploiting the synergy between AOSD and MDD. The CrossMDA-SPL approach defines some artifacts basis for advance the separation clear in between the mandatory (bounden) and optional features in the architecture of SPL. The artifacts are represented by two models named: (i) core model (base domain) - responsible for specify the common features the all members of the SPL, and (ii) variability model - responsible for represent the variables features of SPL. In addition, the CrossMDA-SPL approach is composed of: (i) guidelines for modeling and representation of variability, (ii) CrossMDA-SPL services and process, and (iii) models of the architecture of SPL or product instance of SPL. The guidelines use the advantages of AOSD and MDD to promote a better modularization of the variable features of the architecture of SPL during the creation of core and variability models of the approach. The services and sub-processes are responsible for combination automatically, through of process of transformation between the core and variability models, and the generation of new models that represent the implementation of the architecture of SPL or a instance model of SPL. Mechanisms for effective modularization of variability for architectures of SPL at model level. The concepts are described and measured with the execution of a case study of an SPL for management systems of transport electronic tickets

Squid impact analyser: uma ferramenta para análise de impacto de mudança em linhas de produto de software

Software Products Lines (SPL) is a software engineering approach to developing software system families that share common features and differ in other features according to the requested software systems. The adoption of the SPL approach can promote several benefits such as cost reduction, product quality, productivity, and time to market. On the other hand, the SPL approach brings new challenges to the software evolution that must be considered. Recent research work has explored and proposed automated approaches based on code analysis and traceability techniques for change impact analysis in the context of SPL development. There are existing limitations concerning these approaches such as the customization of the analysis functionalities to address different strategies for change impact analysis, and the change impact analysis of fine-grained variability. This dissertation proposes a change impact analysis tool for SPL development, called Squid Impact Analyzer. The tool allows the implementation of change impact analysis based on information from variability modeling, mapping of variability to code assets, and existing dependency relationships between code assets. An assessment of the tool is conducted through an experiment that compare the change impact analysis results provided by the tool with real changes applied to several evolution releases from a SPL for media management in mobile devices

A framework for investigating the use of face features to identify spontaneous emotions

Emotion-based analysis has raised a lot of interest, particularly in areas such as forensics, medicine, music, psychology, and human-machine interface. Following this trend, the use of facial analysis (either automatic or human-based) is the most common subject to be investigated once this type of data can easily be collected and is well accepted in the literature as a metric for inference of emotional states. Despite this popularity, due to several constraints found in real world scenarios (e.g. lightning, complex backgrounds, facial hair and so on), automatically obtaining affective information from face accurately is a very challenging accomplishment. This work presents a framework which aims to analyse emotional experiences through naturally generated facial expressions. Our main contribution is a new 4-dimensional model to describe emotional experiences in terms of appraisal, facial expressions, mood, and subjective experiences. In addition, we present an experiment using a new protocol proposed to obtain spontaneous emotional reactions. The results have suggested that the initial emotional state described by the participants of the experiment was different from that described after the exposure to the eliciting stimulus, thus showing that the used stimuli were capable of inducing the expected emotional states in most individuals. Moreover, our results pointed out that spontaneous facial reactions to emotions are very different from those in prototypic expressions due to the lack of expressiveness in the latter.
