In web services two points should be considered that end up conflicting: i) the user's right to have his privacy guaranteed and ii) the need of having the services personalized, providing a better user interaction on the Internet. The user's information, with regard to privacy, should be maintained in secrecy, so that the person in question would not feel threatened when using the service. When thinking about personalization, the information should be known and filtered, in a way that makes it possible to discover the most relevant information, so that, together with personalization techniques, they can be used by the sites. This work presents the steps taken for the development of a tool, PrivPerson , capable to analyzing the privacy and personalization mechanisms, being: tools, sites and use sceneries in a way that quantify/measure how much privacy and personalization they offer for the users. For such measurements, a base the taxonomies of classification of privacy and personalization was used, developed in this work and imposed in layers, in a way that it is possible to quantify the privacy and personalization level of offered to the user by the observation of which layers the mechanism meditates. The mechanisms analysis for the proposed tool had the goals to supply the users quantitative values that aid the user in the context of use services. Apart from the above, a Case Study was developed with the objective of identifying the use of the taxonomies on sites, and to compare the manual evaluation on the sites, done in the Case Study, with the automated evaluation found in PrivPerson . With base in this study, it was observed that the sites doesn't have a standardization in the development of their Privacy Politics, based on this, a standardization was developed for such politics, approaching information that are relevant be introduced to the users by the sites.
A ética skinneriana e a tensão entre descrição e prescrição no Behaviorismo Radical
(Universidade Federal de São Carlos, 2007-05-23) Castro, Marina Souto Lopes Bezerra de; Rose, Julio Cesar Coelho de; https://lattes.cnpq.br/3386857761295187; https://lattes.cnpq.br/7823256809341659
From the description of Skinner's theory since its beginning, we can understand the course which falls into ethical questions. Skinner asserts that the science of behavior can also be the science of values, that is, it can explain, it can describe, what we mean by values and what is being ethical, act in a way called ethical. Furthermore, the author argues that, from the radical behaviorism and its selection by consequences theory in the three levels, it is possible to elect a primary value, which can be the guide for somebody who engages in the project of cultural practices in a deliberated fashion. In this way, Skinner assumes a prescriptive attitude, as well as tries to reduce it to a descriptive scope. There it is a kind of tension in the Skinner's texts, because, besides describing the good of the culture, the author elects this value as the primary value. He tries to justify this election appeling to descriptive arguments, but, finally, he cannot find any "good reason". We assume that it is possible to originate ethical precepts from radical behaviorism, nevertheless radical behaviorism is not suficient to justify the choice of one or another precept. We cannot choose, only from its premises, the good of the culture, or the good of others, or the personal goods as the main value, since there are not enough arguments within the theory itself. If we want to explain why we choose this or that precept, on the point of view of the behavior analysis, we must look at the who-makes-the-choice history of contingencies.
