Global stabilizing feedback law for a problem of biological control of mosquito-borne diseases

The control of the spread of dengue fever by introduction of the intracellular parasitic bacterium Wolbachia in populations of the vector Aedes aegypti, is presently one of the most promising tools for eliminating dengue, in the absence of an efficient vaccine. The success of this operation requires locally careful planning to determine the adequate number of mosquitoes carrying the Wolbachia parasite that need to be introduced into the natural population. The latter are expected to eventually replace the Wolbachia-free population and guarantee permanent protection against the transmission of dengue to human. In this paper, we propose and analyze a model describing the fundamental aspects of the competition between mosquitoes carrying Wolbachia and mosquitoes free of the parasite. We then introduce a simple feedback control law to synthesize an introduction protocol, and prove that the population is guaranteed to converge to a stable equilibrium where the totality of mosquitoes carry Wolbachia. The techniques are based on the theory of monotone control systems, as developed after Angeli and Sontag. Due to bistability, the considered input-output system has multivalued static characteristics, but the existing results are unable to prove almost-global stabilization, and ad hoc analysis has to be conducted.

Controladoria e Modelo de Gestão Aplicados às Instituições de Ensino Superior

The establishment of the Nova Lei de Diretrizes e Bases da Educação Nacional (New Law of Policies and Basis of the National Education) was a mark for the Brazilian educational sector. The institutions of advanced education began to seek two major objectives: the continuous improvement of your academic, pedagogic and administrative practice and the elimination of resources waste. Beyond the implementation of the New Law of Policies and Basis of the National Education, many were the factors that contributed for the change of the paradigms of management of the Institutions of Advanced Education in Brazil. Some of these factors are the following: a) Increasing competition. The competition, each time more present in the day-to- day of the Institutions of Advanced Education, that was regional and closed by, it¿s now professional and global.b) Implantation of the mechanism of quality control, for example the Provão (Exam), by the Ministry of Education.c) Increasing demand for the advanced courses, since the number of students concluding the Middle level courses has being increasing gradually in the last years. d) Education has become a critical factor in the competition between nations, regions and companies.In the present moment, marked by intense competition, complex academic and administrative processes, technologic information as a condition ¿ sine qua non¿ for the decisive process and the exigency for modern and cooperated management, demands big changes in the way the educational institutions manage their resources and evaluate the performance of their administrators.The study demonstrates the pressing necessity of implanting a Control Management that will assist the administration of the Institution of Advanced Education in a way that will optimize the economic results of the entity, as well as the creation and implementation of the mechanisms that will bring a better understanding of the environment in which the entity lives and operates.

Governança global e transferência de política: do Protocolo de Cartagena à Política Nacional de Biossegurança

O processo de globalização dos últimos anos evidenciou que as atividades estatais são desagregadas em favor de uma estrutura de relações entre diferentes atores que operam em um contexto global. Neste sentido, esta pesquisa defende que o que pode precisamente ser compreendido como verdadeiramente “global” evidenciado nas últimas décadas do século XX são a transformações das mudanças ambientais em desafios globais. Ao analisar, especificamente, a questão da biossegurança, torna-se importante, portanto, destacar dentro deste contexto de globalização, os aspectos relevantes de governança global (processo no qual diferentes atores estão envolvidos), mais especificamente, a transferência de política, no qual a formulação de políticas públicas para o desenvolvimento social é influenciada por experiências em contextos políticos distintos. Diante disto, foi definido como objetivo de pesquisa analisar como o Protocolo de Cartagena (instrumento legal independente desenvolvido em conformidade com a Convenção sobre Diversidade Biológica em 2000, Montreal) influenciou na formulação e na implementação da Política Nacional de Biossegurança (PNB) brasileira (com base na Lei nº 11.105) no que se refere aos alimentos transgênicos no período de 2000-2009. Para isto, foi realizada uma pesquisa documental sobre o tema de estudo e uma pesquisa empírica por meio de entrevista com pessoas que participam diretamente ou indiretamente na PNB e que, se não participam atualmente, já atuaram nesta Política ou acompanharam seu processo de formulação. Os resultados revelaram que é possível concluir que houve a existência de um processo de transferência de política do Protocolo de Cartagena à PNB, porém no formato de aprendizado (ou lesson drawing).

Structural challenges in a multipolar and multicultural global legal era : BRICS’ global legal politics beyond cultural and economic partnerships

New emerging international dynamics introduce a global poly-axiological polycentric disorder which undermines the tradition of a unique global legal order in international law. Modern Era was characterized by Western European civilizational model – from which human rights is a byproduct. This consensus had its legitimacy tested by XXst century’s scenario – and the ‘BRICS factor/actor’ is a symptom of this reality. Its empowerment in world politics lead to the rise of distinct groups of States/civilizations provided with different legal, political, economic and social traditions – promoting an unexpected uprise of otherness in international legal order and inviting it to a complete and unforeseeable reframing process. Beyond Washington or Brussels Consensus, other custom-originated discourses (Brasília, Moscow, New Delhi, Peking or Cape Town Consensus, among other unfolded possibilities) will probably henceforth attempt shaping international law in present global legal disorder.
