Ética na pesquisa em Administração

Ethics on scientific research is approached and often discussed in several areas of knowledge connected to health. In the Administration area there are very few studies which approach the topic of ethics on research. The present paper tried to fill in this gap in the production of knowledge about the topic, investigating how the ethical principles found in the literature and in the codes of conduct are noticed and taken into account in Administration research activities developed by acting researchers in Administration Post Graduation Programs. Theoretically speaking, the study was based mainly on the approaches by Creswell (2007) and Bell and Bryman (2007), which discuss the research ethical principles. Methodologically speaking it was all about an exploratory kind of study, with qualitative research approach. Upon data collection, personal interviews were made aiming at its depth and focus groups were formed. The first stage had interviews with four experienced researchers who took part on a teaching and researching event and on the second stage we used the focus group technique. The focus groups were done in four college institutions along with the post graduation programs in Administration in the states of Rio Grande do Norte, Paraíba and Pernambuco, in Brazil. The results suggest the existence of general principles and parameters for the scientific research recommended in the literature and on official resolution. However, in the Administration area, there are only a few recommendations of good practices when it comes to submitting articles for scientific publications but we found no guidance with ethical principles and parameters which cover all the activities in the scientific research and which specifically meet the research particularities in Administration. The main ethical dilemma pointed by the researchers refers to ethical questions which arise at the time of data collection and on disclosing the results. Most researchers do not know the guidelines and the ethical norms on ethics about research that we have in our country neither do they send in their projects to the research ethics committee. When dilemma arises, they decide the ethical question based on their values and common sense. These elements confirm the thesis that the researcher s procedure in the research activities in Administration is predominantly signed by personal values or by common sense and less by ethical principles, whether by not knowing the normative instruments related to ethics or by disagreeing with any disciplining rules on ethical behavior in the research

Uma cidade para pessoas: funcionalidade, racionalidade e emotividade nas relações mobiliário urbano, espaço público e cidadãos

This research investigates how functionality, rationality, and emotionality applied to urban furniture design contribute to the organization, legibility, and qualification of public spaces, according to different layouts, physical and visual qualities of the urban furniture as well as the quality of urban infrastructure that may influence the uses and appropriation of urban spaces by pedestrians, turning those spaces into socially centripetal or centrifugal places. The work consists of two parts. First refers to a bibliographical review concerning two main issues of the investigation: product design and legibility of public space, defining the conceptual and theoretical bases, linked to methodological strategies aimed at systemic planning and integrated management of urban furniture design and legibility of public spaces (sidewalks), that are necessary to define the existing relationships among the user s interface (pedestrians); product (urban artifacts); built environment (sidewalks). The second part refers to the achievement of empirical approach throughout visual analysis of public spaces and the functional and qualitative evaluation of the existing urban furniture in the central neighborhood of Cidade Alta, Natal, RN, according to the theoretical researched concepts and methodological procedures. The results expose the weaknesses and levels of intensity arising from the relations among public space, urban furniture, and users, revealing the need for theoretical and practical approaches which would help the decision-making in planning, designing and integrating innovative, sustainable, and ethical solutions in order to design attractive public spaces that could provide sociability and citizenship throughout integrated public management, city systemic thinking and urban identity. The suggested guidelines at the end of this research will provide the necessary strategies to design suitable urban furniture systems according to aesthetic and practical urban infrastructure and city context, aiming to ease visual and physical conflicts that may negatively interfere with the appropriation of public spaces by the citizens

A organização do processo de projeto de arquitetura no meio profissional: uma análise da produção em escritórios

This paper examines, through case studies, the organization of the production process of architectural projects in architecture offices in the city of Natal, specifically in relation to building projects. The specifics of the design process in architecture, the production of the project in a professional field in Natal, are studied in light of theories of design and its production process. The survey, in its different phases, was conducted between March 2010 and September 2012 and aimed to identify, understand, and analyze comparatively, by mapping the design process, the organization of production of building projects in two offices in Natal, checking as well the relationships of their agents during the process. The project was based on desk research and exploration, adopting, for both, data collection tools such as forms, questionnaires, and interviews. With the specific aim of mapping the design process, we adopted a technique that allows obtaining the information directly from employee agents involved in the production process. The technique consisted of registering information by completing daily, during or at the end of the workday, an individual virtual agenda, in which all agent collaborators described the tasks performed. The data collected allowed for the identification of the organizational structure of the office, its hierarchy, the responsibilities of agents, as well as the tasks performed by them during the two months of monitoring at each office. The research findings were based on analyses of data collected in the two offices and on comparative studies between the results of these analyses. The end result was a diagnostic evaluation that considered the level of organization and elaborated this perspective, as well as proposed solutions aimed at improving both the organization of the process and the relationships between the agents under the lens analyzed

Metodologias estatísticas aplicadas a dados de análises químicas da água produzida em um campo maduro de petróleo

Produced water is characterized as one of the most common wastes generated during exploration and production of oil. This work aims to develop methodologies based on comparative statistical processes of hydrogeochemical analysis of production zones in order to minimize types of high-cost interventions to perform identification test fluids - TIF. For the study, 27 samples were collected from five different production zones were measured a total of 50 chemical species. After the chemical analysis was applied the statistical data, using the R Statistical Software, version 2.11.1. Statistical analysis was performed in three steps. In the first stage, the objective was to investigate the behavior of chemical species under study in each area of production through the descriptive graphical analysis. The second step was to identify a function that classify production zones from each sample, using discriminant analysis. In the training stage, the rate of correct classification function of discriminant analysis was 85.19%. The next stage of processing of the data used for Principal Component Analysis, by reducing the number of variables obtained from the linear combination of chemical species, try to improve the discriminant function obtained in the second stage and increase the discrimination power of the data, but the result was not satisfactory. In Profile Analysis curves were obtained for each production area, based on the characteristics of the chemical species present in each zone. With this study it was possible to develop a method using hydrochemistry and statistical analysis that can be used to distinguish the water produced in mature fields of oil, so that it is possible to identify the zone of production that is contributing to the excessive elevation of the water volume.

Semeadora-adubadora: mecanismos de corte de palha e cargas verticais aplicadas

This work had as objective to evaluate the performance of mechanisms of cutting of the no-tillage seedrills in different vegetable coverings and applied vertical loads. The experimental design used was in randomized blocks and factorial scheme 3 x 4, with four replications. The trials were accomplished with three different mechanisms of culting of the straw (plane disc, corrugated disc and wavy disc), using four different vertical loads (750, 1500, 2250 and 3000 N). All treatments were accomplished in five straw coverings (corn, sorghum, triticale, black oats and radish). The results showed that larger the amount of dry matter covering the soil, higher the demand of horizontal and vertical forces. The wavy disc promotes the largest values of area of mobilized soil and requires large horizontal force, vertical force and horizontal force per area of cutting depth of discs (specific force). The treatment with plane disc required higher values of the horizontal forces per area of mobilized soil and of vertical force in the corn and sorghum coverings.

Sintomas da intoxicação inicial de Eucalyptus proporcionados por subdoses de glyphosate aplicadas no caule ou nas folhas

Com o objetivo de avaliar os sintomas de intoxicação causados pela aplicação de glyphosate, foi montado um estudo composto por quatro ensaios com aplicações de glyphosate (360 g e.a. L-1) em eucalipto. em todos os ensaios, mudas foram transplantadas em vasos de 5,0 L. Nos ensaios 1 e 2, foram aplicados volumes crescentes de solução de glyphosate no caule do eucalipto. No ensaio 1, a solução de 3% (v/v) foi aplicada nos volumes de 0, 1, 5, 10, 20, 40, 80 e 160 µL de calda por planta e, no segundo, a solução de glyphosate a 2% (v/v) foi aplicada nos volumes de 0, 1, 5, 15, 30, 60, 90, 120 e 150 µL de calda por planta. Nos ensaios 3 e 4, foram feitas aplicações de glyphosate sobre as plantas de eucalipto. No ensaio 3, as doses foram de 0, 7,2.10-7, 7,2.10-6, 7,2.10-5, 7,2.10-4, 7,2.10-3, 7,2.10-2, 7,2.10-1, 7,2, 72, 360 e 720 g e.a. de glyphosate ha-1 e, no ensaio 4, de 0, 9, 18, 36, 72, 144, 288, 432, 576, 720, 1.080, 1.440 e 2.160 g e.a. de glyphosate ha-1. Nos quatro ensaios foi utilizado o delineamento DIC, com três repetições. Nas plantas, foram avaliadas a altura, a área foliar e a matéria seca de caule e folhas. Os resultados obtidos foram submetidos a análises de regressão. Quando aplicadas no caule, doses de 40,78 e 51,41 µL de calda por planta de glyphosate a 3 e 2% (v/v), respectivamente, nos ensaios 1 e 2, foram suficientes para redução média de 50% das características estudadas. Nas aplicações sobre as folhas, houve maior sensibilidade das plantas mais desenvolvidas. Para redução média de 50% nas variáveis analisadas, foram necessárias doses de 277,4 e 143,3 g e.a. de glyphosate ha-1 nos ensaios 3 e 4, respectivamente.
