The present text has the objective of presenting theoretical considerations regarding two types of strategy of research: phenomenology and ethnography. Based on a hermeneutic approach, the two conceptual propositions are presented, the first being dealt with in the sociological context, and the second presented as an anthropological basis. Their similar uses in an organizational context - as well as their differences - are highligthed according to the theoretical contributions of authors belonging to the qualitative universe of organizational research. The text reveals, by the presentations of reported theoretical assumptions, the relevance of the interpretative perspective for the conduction of research that has the organization as object of study, in the pursuit of the identification of ways of constructing the social reality that is the result of the analysis of meanings and experiences lived by the participants, highlighting the importance of the bond between researcher and the research object The theoretical discussion regarding the two perspectives allows to observe the competence of the phenomenological and ethnographic research practice within the field of organizational studies, showing their methodological possibilities to identify dynamics that relate to the experience of life, favoring the analysis of the human being as a phenomenon of interpretation. © FECAP.

Mineral research works are fundamentals for recognition and incorporation of new reserves. This paper present an integrated analysis of geologic and metallogenetics data, with results gotten from the application of the Induced Polarization geophysical method, in an copper ore occurrence, inserted in Camaquã sedimentary basin, situated in northeast of Caçapava do Sul city (RS). In area ocurr arkosean arenites average coarse, the intensely silicified and recrystallized, pertaining to Passo da Promessa Formation. The presence of azurita and malachite in breakings and high porosity zones of the host rock characterizes the mineral occurrence in surface, located in the crossing two fault families. The inversion models indicate the predominance of high chargeability in vulcanics tuff, rock of high porosity in relation to the andesites and metaconglomerates gifts in the area. The strong structural control of the mineral occurrence associated the high chargeability in volcanic tuff is indications of the hydrothermal fluid access by means of faults, until rocks with great porosity, where it occurred disseminations of copper sulfides in depth and carbonates in surface.

Cosmetic Dermatology is a growing subspecialty. High-quality basic science studies have been published; however, few double-blind, randomized controlled clinical trials, which are the major instrument for evidence-based medicine, have been conducted in this area. Clinical research is essential for the discovery of new knowledge, improvement of scientific basis, resolution of challenges, and good clinical practice. Some basic principles for a successful researcher include interest, availability, persistence, and honesty. It is essential to learn how to write a protocol research and to know the international and national regulatory rules. A complete clinical trial protocol should include question, background, objectives, methodology (design, variable description, sample size, randomization, inclusion and exclusion criteria, intervention, efficacy and safety measures, and statistical analysis), consent form, clinical research form, and references. Institutional ethical review board approval and financial support disclosure are necessary. Publication of positive or negative results should be an authors' commitment. © 2013 by Anais Brasileiros de Dermatologia.

This article aims to identify the main definitions, practices and related avenues for future research on green supply chain management (GSCM). From a systematic literature review and analysis in major journals related to the topic and indexed in Scopus, was possible: a) identify key research goals of the articles analyzed, b) the research methodology adopted, c) the predominant industrials sectors studied, and d) the practices of GSCM considered relevant by researchers. Results are presented in each of these analytical perspectives. These results may be useful both for those interested in environmental management and in supply chain management, in view of the growing interest in GSCM.

The goal of this research is to analyze what are the key variables and factors that, in the perception of researchers in the field of sustainability in Brazil, may be influencing the impact research conducted by them. Therefore, we designed a data collection instrument with 14 variables, responded online by 89 researchers in the field of sustainability in Brazil. The results show that these researchers realize the impact of their research as a process influenced by four factors.

Objective: The objective of this study was to assess the opinions of the Brazilian population about incentives for oocyte donation. Methods: A cross-sectional descriptive approach was used to consult the Brazilian public. The data collection involved the use of a structured questionnaire about legal and ethical issues surrounding oocyte donation. Individuals were randomly selected from the general population using different e-mail lists. Potential participants were contacted by e-mail and invited to participate in the study by completing an online web survey. Results: A total of 1,565 people completed the survey, including 1,284 women(82%) and 281 men(18%). Among the respondents, 1,309(83.6%) were university graduates, 1,033(66%) had a personal income ≥1,250 US dollars/month, 1,346(86%) considered themselves to be religious and 518 (33.1%) were health professionals. While many participants believed that women may donate their oocytes for altruistic reasons, the majority believed that a lack of oocyte donations is due to the prohibition of payments(64.3%) and that incentives would facilitate the decision to donate oocytes(84.7%). The majority of the participants(65.3%) agreed that a financial incentive(i.e., paying the donor) would be the most practical solution for increasing the number of oocyte donations. These results tended to be independent of gender, age, income, religion, education level and profession. Conclusion: While the Brazilian Federal Council of Medicine prohibits payments for oocyte donation, the majority of study participants had no objection to compensating oocyte donors. Moreover, most of the participants agreed that a financial incentive is the most practical solution to increasing the number of oocyte donations.
