Multivariate analysis for selecting animals for experimental research

Background Several researchers seek methods for the selection of homogeneous groups of animals in experimental studies, a fact justified because homogeneity is an indispensable prerequisite for casualization of treatments. The lack of robust methods that comply with statistical and biological principles is the reason why researchers use empirical or subjective methods, influencing their results. Objective To develop a multivariate statistical model for the selection of a homogeneous group of animals for experimental research and to elaborate a computational package to use it. Methods The set of echocardiographic data of 115 male Wistar rats with supravalvular aortic stenosis (AoS) was used as an example of model development. Initially, the data were standardized, and became dimensionless. Then, the variance matrix of the set was submitted to principal components analysis (PCA), aiming at reducing the parametric space and at retaining the relevant variability. That technique established a new Cartesian system into which the animals were allocated, and finally the confidence region (ellipsoid) was built for the profile of the animals’ homogeneous responses. The animals located inside the ellipsoid were considered as belonging to the homogeneous batch; those outside the ellipsoid were considered spurious. Results The PCA established eight descriptive axes that represented the accumulated variance of the data set in 88.71%. The allocation of the animals in the new system and the construction of the confidence region revealed six spurious animals as compared to the homogeneous batch of 109 animals. Conclusion The biometric criterion presented proved to be effective, because it considers the animal as a whole, analyzing jointly all parameters measured, in addition to having a small discard rate.

Construção de índice percentual de “status” de desenvolvimento sus-tentável de assentamentos rurais utilizando procedimento estatísti-co multivariado

The objective of the present work is the construction of percentual indexes of sustainable development "Status" - PIDSD (%) aiming to order and classify the rural settlements, considering agricultural, socioeconomic and environmental aspects, in order to diagnose their sustainable reality. This way, we considered multivariate statistical procedure to establish analytical descriptors - indexes - like the principal components technique (CP). The CP technique was used in a matrix formed by 47 variables observed in 50 rural settlements, distributed in seven different regions of the state of Mato Grosso, obtained from diagnostics, provided by "Mato-Grossense" Enterprise of Research, Assistance and Rural Extension S/A - EMPAER - MT, in order to obtain the indexes used in the construction of PIDSD (%). The settlements with higher PIDSD (%) were considered "higher potential" or "higher sustainable" in relation to the analyzed variables, making the establishment of assistance strategies and cooperation possible, allowing the government and civil society in general, to improve those with worse results ("lower potential" or "lower sustainable"), and search for ways to strengthen and multiply the results of the "higher potential" settlements. Vale do Seringal settlement had the best conditions in relation to the variables, mainly those of higher weigh and was considered the one with "higher potential". São Sebastião had the worst conditions and was considered "lower potential".

A responsabilidade social no processo de adoção de inovação em empresas sucroenergéticas do centro-oeste do Estado de São Paulo.

The main objective of this paper was to verify the influence of the organization and management in social responsibility the decision of adoption, choice, justification and implementation of innovation in elaborates of sugar, ethanol and energy companies of the midwestern state of São Paulo. Using multivariable analysis of principal components and clusters, the variables were analyzed and companies classified. Adapted to contemporary situations, the Freeman (1975) model of taxonomies was the parameter with research information in personal interviews by semi-structured questionnaires. The activities investigated were the existence of programs and organization to improve the welfare and quality of life to employees and family (leisure, culture, health, self-knowledge, values, beliefs etc.), program and social volunteering organization for the community, programs and organization to encourage the training of educators and extension education and incentive programs and organization to research and scientific production. It was concluded that the best companies which included, in their organization structures, management practices embodied in social responsibility.

Análise multivariada das atividades científicas e técnicas no processo de adoção de inovação em empresas sucroenergéticas do centro-oeste do estado de São Paulo

The primary objective of this study was to verify the existence of internal organization and processes influencing the decisions on adoption, choice, justification and implementation of innovative practices of scientific and technical activities undertaken in the elaborates of sugar, ethanol and energy companies of the midwest of the state of Sao Paulo. Using multivariate analysis of principal components and clusters, the variables were analyzed and the companies, classified. The taxonomy model adapted to contemporary situations described by Freeman (1975), was the 'parameter used with research information in personal interviews by semi-structured questionnaires. The investigated activities constituted of: basic research; applied research; experimental development; scientific and technical information; long-term planning. The variables analyzed were: production processes, operating systems, development of new products, projects and implementation of pilot plant for new products, development, knowledge, studies of other business segments, number of innovations, and the number of existing employees in the organizational structure for these purposes. It was concluded that the best companies with innovative attitudes are those that have incorporated into their organizational the structures, practices and techniques of scientific activities.
