Estudo das práticas no desenvolvimento de sistemas de apoio a decisão com enfoque em fatores ambientais e perfis dos usuários

A utilização de Sistemas de Apoio a Decisão (SAD) tem se tornado mais frequente no âmbito empresarial, bem como em algumas decisões pessoais. Porém, a análise, o desenvolvimento e a implantação desse tipo de sistema não é uma tarefa trivial. Os analistas responsáveis por todo ciclo de vida do desenvolvimento do SAD, encontram várias dificuldades nas análises das necessidades dos usuários e na futura satisfação no uso do sistema. Esse tipo de problemática provém, em muitos casos, da necessidade de considerar além das necessidades básicas do usuário, também considerar os fatores ambientais que impactam nas suas atividades, bem como características do seu perfil. Diante da complexidade exposta, faz-se necessário a criação de um modelo de ciclo de vida para o desenvolvimento do SAD, que considere os fatores ambientais inerentes às atividades e aos perfis dos usuários, aglutinando-os nas estruturas do SAD. Esse estudo visa à proposição de recomendações e melhores práticas para os analistas responsáveis pelo desenvolvimento do SAD, identificando as fases críticas para cada estrutura do mesmo, criando um modelo de ciclo de vida com essas fases, bem como as iterações entre ela

Modeling sequential bargains and personalities in democratic deliberation systems: A NSS for social-efficient agreements

Purpose: This paper aims to introduce a negotiation support system (NSS) with a theoretical modeling that considers the aspects of human personality and negotiator’s behavior to assist the decision-making of public managers and stakeholders in democratic bargaining processes and support social-efficient outcomes. Design/methodology/approach: A game theoretical modeling of public participatory negotiations characterized by complete and perfect information is explored with the inclusion of personality aspects and negotiation styles. The importance of the negotiation knowledge disclosure in the sequential bargains of participative budgeting is highlighted by an experiment with 162 state-owned companies’ managers and graduate students to present the contribution of the system’s applicability. Findings: A considerable number of Pareto-efficient deliberation agreements are obtained with few interactions when the negotiation strategies and the personality aspects of opponents and stakeholders are freely available (a symmetry in the public negotiation knowledge). In addition to the set of Pareto-efficient agreements, those with the best social outcome (i.e. that maximize the group satisfaction despite individual losses) are observed when the informational tool for personality and negotiation style inference is enabled. Originality/value: Many scholars argue for Pareto-efficient allocation instead of equal divisions of resources within participative democracies and public governance. This work provides a new system with an empirical application and theoretical modeling which may support those arguments based on the nonverbal negotiation aspects

Alcohol and violent behavior among football spectators: An empirical assessment of Brazilian's criminalization

The relationship between alcohol and the violent behavior, expressed as branches of hooliganism, is receiving considerable theoretical attention in social and psychological literature along the past decades while empirical researches on that matter are taken for granted. The falling in appreciate such empirical approach relies on the difficult it requires to compare of two different realities; one with alcohol intake and another without it, in order to evaluate whether it might drive sport spectators into a violent behavior, holding everything else constant. This work provides such robust statistical assessment taking into consideration a Brazilian state law 13748 of April 2009, which prohibited the sale of alcoholic beverages in Pernambuco's football stadiums. We consider the effectiveness of alcohol intervention on hooligan behavior by means of non-parametric test and a autoregressive moving average series, resorting to over ten years of data (before and during the criminalization) with regard aggression and unruly conduct committed by fans before in football matches within 3 miles from the stadium. Our results bring support to the decision of Pernambuco State Legislature to abolish in January 2016 the law in favor of the legalization of alcoholic beverages sales

Exploring the Bedouin Syndrome in the Football Fan Culture: Addressing the Hooliganism Phenomena through Networks of Violent Behavior

The Bedouin syndrome represents social interactions based on four premises: a friend of my friend is my friend, a friend of my enemy is my enemy, an enemy of my friend is my enemy, and an enemy of my enemy is my friend. These extensive associations exist in many social and economic relationships, such as market competition, neighborhood relations, political behavior, student gangs, organized crime, and the violent behavior of sports spectators (hooliganism) worldwide. This work tests the Bedouin syndrome hypothesis considering the violent behavior in the football fan culture. We construct relational networks of social affinities to represent the social interactions of organized fan bases (Torcidas organizadas) involved in hooligan violence in Pernambuco, Brazil. Contrary to prior expectations, the results evidence no statistical support for the Bedouin syndrome in 13 of the 15 analyzed clubs. There is weak statistical support in two interactions and strong statistical support in one interaction to state that a friend of my enemy is my friend (instead of an enemy). The only support for the Bedouin syndrome is circumstantial based on a prior assumption of an alliance. We propose a network development that can be more suitable to represent football fans’ violent behavior. The results contribute to understanding the hooliganism social phenomenon in football-rooted cultures and their impact on public health, identifying potential determinants for organized violence by young spectators’ and supporting police strategies by defining relevance scores for the most potential clashes and coalitions of gangs
