Estudo da anatomia interna dos pré-molares – Revisão de literatura

Abstract: Introducao: com a intencao de reforcar a estreita relacao existente entre o conhecimento da anatomia interna e a obtencao do sucesso no tratamento endodontico, sao relatadas aqui caracteristicas da anatomia interna presentes no grupo dental dos pre-molares. Revisao de literatura: as alteracoes morfologicas quando desconsideradas podem dificultar a terapia endodontica. A resolucao de casos com anatomia incomum exige consequentemente, mudancas no metodo de diagnostico, assim como no tratamento. Conclusao: a identificacao, e, portanto, o tratamento satisfatorio de raizes e canais diferenciados, diminui a persistencia dos sinais e sintomas, reduzindo, assim as possiveis causas de um retratamento. Palavras-chave: Anatomia; Endodontia; Pre-molar.

La gestión del conocimiento en cadenas hoteleras: una revisión

Abstract: Knowledge management seeks to make the organization operates the smartest way possible to ensure its viability and success, as well as using the most resources and ensure its constant renewal. The objective of this research is to discuss the main concepts related to knowledge management and its application in chains. We conducted a literature review and exploratory research. We present the main definitions of knowledge management, the main models and the use of knowledge management in chains. It was identified that a hotel chain that wants to be successful in its operation and management should seek to possess institutional knowledge on the market, knowing the profile of customers, suppliers, competitors and stakeholders.

Ethics and/or Success in Conducting Organization Studies: A Habermasian Account

Abstract: In profit organizations most of all, the critical organizational research has faced problematic conditions. In general, one of the biggest problems in the broad field of organizational research is the difficulty of accessing data from an organization and even of entry (Bell, 1999). In part, this difficulty occurs because managers may fear that the research data will be used against the organization and its members. They often see organizational researchers as a threat. In this sense, organizational research is hard to undertake, because the members of an organization are often afraid that the claims made by researchers will be disturbing (Alvesson & Deetz, 2000). They are afraid of what researchers will do with the collected data, or what they may request in their interaction with the organization. For this reason, it is very common for staff to ignore information, hide important data, or in some other way make the research project unfeasible. This is partly because organizational researchers are nowadays more and more concerned with ethics in particular. In the broad field of management research, the ethical theme seems to be growing into one of the most important study subjects developed in recent years, partly in consequence of the reflexivity and criticism surrounding the role of management and the influence of the dominant corporate interest in the results of managers' actions (Parker, 1998). In critical organization studies, business ethics is a central theme, in particular, as a subject of criticism for its anti-foundationalist ethical approach (Collins & Wray-Bliss, 2005). This paper deals with this problem by seeking to clarify how ethics is considered by organization researchers when engaged in fieldwork. To reach this point, it adopts Habermas' view of discursive ethics, concentrating on his conception of strategic action. For Habermas, this kind of social action is the opposite of communicative action, an act of speech free of constraint, which is also concerned with ethical commitment. In this sense, strategic action lacks ethical claims because it is an action oriented to performative and utilitarian interests. This argument is demonstrated by presenting three different research examples, which reveal how strategic action emerges in critical research enterprises and how ethical claims are disregarded in this situation. In the end, I explore my own research experience, telling a confessional story, which shows an example of strategic action in critical organizational research. This paper is structured in five parts. First, it discusses the locus of ethics in organization studies, which is not only an important subject for criticism, but also a subject for serious consideration in research practice. Then, it discusses Habermas' Theory of Communicative Action, introducing his theoretical framework of discursive ethics. Next, it moves to discussing how strategic action appears in critical organizational research. Following this, I give a confessional example from my fieldwork experience. Finally, the conclusion is reached that many critical researchers adopts opportunistic behaviour in response to academic pressures, which are exerted to guarantee the productivity claim of capitalist interests, in the same way as any other job in our society. The locus of ethics in organization studies Organization researchers usually deal with ethics in the sense of reporting the ideological orientation of such management practices as imply unethical behaviour (for example, Banerjee, 2008; Shrivastava, 1986). In this sense, the unethical orientation of managers has been seen as something masked by a manipulative discourse, which has built the false impression that management practices are ethically oriented. This means that organization researchers often see as problematic the way in which managers and corporations build a false sense of morality around their recent work on social programmes; for example, those for corporate social responsibility and employees' health (Collins & Wray-Bliss, 2005; Haunschild, 2003; Parker, 1998; Roberts, 2003). …

A aprendizagem baseada em problemas (ABP) como metodologia de ensino na disciplina de embriologia na visão do aluno

Abstract: O metodo de ensino da aula expositiva tradicional, baseado na passividade do aluno, tem sido repensado e questionado ao longo dos ultimos anos, desde os niveis basicos ate a pos-graduacao. Entre as metodologias ativas mais utilizadas encontra-se a Aprendizagem Baseada em Problemas (ABP). O objetivo deste estudo foi comparar a motivacao e a percepcao de aprendizado em alunos na disciplina de embriologia apos aulas expositivas tradicionais e apos encontros no modelo pedagogico da ABP. Apos a discussao dos temas, os alunos responderam a um questionario e os dados coletados foram tabulados e comparados por meio do teste qui-quadrado. Os resultados nos permitem concluir que, a partir do delineamento experimental proposto, os alunos avaliaram melhor o metodo tradicional e consideram que aprendem mais em aulas expositivas do que na aprendizagem baseada em problemas. No que se refere a motivacao para realizar trabalhos em equipe, comuns na tecnica da ABP, nao observamos diferencas significativas na comparacao dos alunos que responderam ao questionario antes e apos a metodologia ativa, sinalizando que a atividade do ABP nao alterou o ponto de vista dos alunos a respeito dos trabalhos em equipe.
