Esta pesquisa retratou o processo de comunicação e marketing político na vida pública de Wenceslau Braz, presidente do Brasil de 1914 a 1918. Ela abordou a política brasileira daquela época e mostrou as estratégias de convencimento usadas para indicação do mineiro ao cargo, revelando de que maneira a imprensa da época reagiu nesse período eleitoral. A metodologia que norteou essa dissertação foi a de Estudo de Caso , baseado nos conceitos básicos de Robert Yin, onde foram realizados vários estudos bibliográficos, documentais e entrevistas com familiares e amigos de Wenceslau. Complementarmente quatro publicações da imprensa brasileira foram analisadas. Conclui-se que a participação da imprensa nesse processo foi bem irrelevante e o processo eleitoral foi ditado pelo regime político da época.

Recent surveys reveal that many university students in the U.K. are not satisfied with the timeliness and usefulness of the feedback given by their tutors. Ensuring timeliness in marking can result in a reduction in the quality of feedback. Though suitable use of Information and Communication Technology should alleviate this problem, existing Virtual Learning Environments are inadequate to support detailed marking scheme creation and they provide little support for giving detailed feedback. This paper describes a unique new web-based tool called e-CAF for facilitating coursework assessment and feedback management directed by marking schemes. Using e-CAF, tutors can create or reuse detailed marking schemes efficiently without sacrificing the accuracy or thoroughness in marking. The flexibility in marking scheme design also makes it possible for tutors to modify a marking scheme during the marking process without having to reassess the students’ submissions. The resulting marking process will become more transparent to students.

The use of liposomes as vaccine adjuvants has been investigated extensively over the last few decades. In particular, cationic liposomal adjuvants have drawn attention, with dimethyldioctadecylammonium (DDA) liposomes as a prominent candidate. However, cationic liposomes are, in general, not sufficiently immunostimulatory, which is why the combination of liposomes with immunostimulators has arisen as a strategy in the development of novel adjuvant systems in recent years. One such adjuvant system is CAF01. In this review, we summarize the immunological properties making CAF01 a promising versatile adjuvant system, which was developed to mediate protection against tuberculosis (TB) but, in addition, has shown promising protective efficacy against other infectious diseases requiring different immunological profiles. Further, we describe the stabilization properties that make CAF01 suitable in vaccine formulation for the developing world, which in addition to vaccine efficacy, are important prerequisites for any novel TB vaccine to reach global implementation. The encouraging nonclinical data led to a preclinical vaccine toxicology study of the TB model vaccine, Ag85B-ESAT-6/CAF01, that concluded that CAF01 has a satisfactory safety profile to advance the vaccine into phase I clinical trials, which are scheduled to start in 2009.
