A Intensidade da Exploração Agropecuária como Indicador da Degradação Ambiental na Região dos Cerrados, Brasil AgEcon
Cunha, Nina Rosa da Silveira; Lima, Joao Eustaquio de; Gomes, Marilia Fernandes Maciel; Braga, Marcelo Jose.
Being constituted as the largest risk factor and effective degradation to the Savannah, the man’s intervention in the nature and, especially, the agricultural exploration require analysis and better monitoring. This work aims to analyze the relationship between the agricultural exploration and the environmental degradation in the area of the Savannahs, in 1995-1996. In particular, it is intended, to use multivariate statistical analysis, to verify the factors associated with the intensity of farming predominant in the determination of the degradation pattern, and to obtain indexes of exploration intensity to make possible to categorize and to group the microrregions in terms of degradation potential. The results showed that the intensity of the...

Are commercial logbook and scientific CPUE data useful for characterizing the spatial and seasonal distribution of exploited populations? The case of the Celtic Sea whiting ArchiMer
Verdoit, Marion; Pelletier, Dominique; Bellail, Robert.
A statistical approach is proposed to utilize the information contained both in scientific surveys and commercial fishing logbooks, in order to determine spatial and temporal distributions of recruiting and spawning fish of exploited populations. The approach is based on multivariate descriptive methods including ordination methods and classification techniques. A typology involving a principal component analysis (PCA), followed by a hierarchical ascending classification (HAC), is applied to both scientific and commercial data. PCA that accounts for spatial and temporal contiguities were performed. These analyses allow to compare structures observed at global and local scales, with those observed without focusing on a particular scale. The method is...

Determinantes e Hierarquização do Índice de Desenvolvimento Rural dos Municípios Mato-grossenses (2006) AgEcon
Pereira, Benedito Dias; Oyamada, Graciela Cristine; Silva, Gerson Rodrigues; Faria, Alexandre Magno; Seba, Maristela Almeida.
Mato Grosso ao longo de sua história passou de uma economia baseada na pecuária para uma economia essencialmente agrícola, destacando-se no cenário agrícola nacional e mundial pelas suas produções e exportações de soja e algodão, dentre outros bens de origem agropastoril. Este trabalho tem como propósito compreender a heterogeneidade espacial do desenvolvimento rural mato-grossense a partir do grau de desenvolvimento de cada município. Com base em dados secundários, com recorrência à análise fatorial, adaptada de Melo & Parré (2007), ajustada para Mato Grosso, constatou-se que mais da metade dos municípios (60,99%) do Estado se posicionam abaixo da média do grau de desenvolvimento encontrada (52,99), enquanto que apenas 30,99% situam-se acima...

Factor structure of Bech's version of the Brief Psychiatric Rating Scale in Brazilian patients BJMBR
Crippa,J.A.S.; Sanches,R.F.; Hallak,J.E.C.; Loureiro,S.R.; Zuardi,A.W..
The objective of the present study was to evaluate the factor structure of Bech's version of the Brief Psychiatric Rating Scale (BPRS), translated into Portuguese. The BPRS was administered to a heterogeneous group of psychiatric inpatients (N = 98) and outpatients (N = 62) in a University Hospital. Each patient was evaluated from one to eight times. The interval between consecutive interviews was one week for the inpatients and one month for the outpatients. The results were submitted to factorial analysis. The internal consistency of the total scale and of each factor was also estimated. Factorial analysis followed by normalized orthogonal rotation (Varimax) yielded four factors: Withdrawal-Retardation, Thinking Disorder, Anxious-Depression and...

Índice de desempenho competitivo das empresas de móveis da região metropolitana de Belém AgEcon
Gama, Zilda Joaquina Cohen; Santana, Antonio Cordeiro de; Mendes, Fernando Antonio Teixeira; Khan, Ahmad Saeed.
The furniture industry of the Metropolitan Region of Belém provides many jobs opportunities and help to reduce the environmental impacts of sawmill, given that the shavings and wood residues of these firms are used as raw material. Factorial analysis was used to estimate the index of competitive performance (ICP) and to determine the competitive position of the firms in the furniture industry. The results showed that most of the furniture firms were located in an intermediate competitive level, which is due to the limiting factors such as lack of workforce, low technological level, difficult access to credit and low level of horizontal and vertical integration in the supply chain. The final results showed that only one, among the furniture firms, achieved...

The agricultural activity possesses expressive relevance for the agriculture of the North region. In relation to the agricultural modernization, the researches are driven in a joined way (national), the one that disables verify, indeed, which the degree of municipal development and which the variables that to impact this development. In a general way, it intends to determine the degree of agricultural modernization in the municipal districts of the North region. It is observed that this area presents low state levels of modernization, which are justified for the recent expansion of the agricultural border, for the low level of government investments, for the lack of public politics destined to the agricultural development and, finally, for the movements...

L'huître creuse Crassostrea gigas en Bretagne. Résultats du réseau de suivi de 1990 ArchiMer
Le Bec, Claude; Mazurie, Joseph.
The year 1990 is the second of a regional monitoring program on production assessment of Crassostrea in Britlany. 9 sites have been tested with 3 stations per site and 3 oysters bags in each station, at 3 different densities : 170, 210 and 250 oysters per bag. 18 month old oysters stocked in bags in march were analyzed 43 weeks later, by variables concerning growth, survival, quality... The growth was lower at higher densities, more or less according to sites. As previously, differences between sites and stations are observed, with some confirmations (higher mortalities in Aber Benoît site) and also evolutions (growth and Polydora infestations improvement in Pen Bé site).

L'huître creuse Crassostrea gigas en Bretagne. Résultats du réseau de suivi de 1991 ArchiMer
Le Bec, Claude; Mazurie, Joseph.
The year 1991 is the third one of the regional network on growth assessment of Crassostrea gigas in Brittany, wearing on 9 sites and 3 stations per site. 2 bags of 210 oysters, 18 month old, were placed in each station. Comparatively to previous years, the 1991 growth was moderate, and condition index inferior. However, the survival rates were very high (above 91 %) and most of the slight mortalities occurred a short time after stocking (as revealed by the sizes of dead shells). An improvement was also observed in the infestation rate by the polychaete Polydora sp..Most of the growth differences between sites and stations are still present. An analytical study including environmental variables would be necessary for explanations and will be tempted in 1993.

ABSTRACT The objective of this study was to evaluate the effect of the trainer and the adopted daily work on the behavior and performance of horses of the Mangalarga Marchador breed on a horse farm and in racetracks in northern Minas Gerais State, Brazil. Twenty equines and nine trainers from four farms and three competition events of the breed were observed. The experiment was divided into two stages. In the first stage, the animals were observed together with their trainer on the farm, during the daily work, and the behavior reactions were recorded based on scores. The duration of training and the behavior told by the trainer of the animal were recorded in scores. The second stage happened in three competitions of the breed in agricultural fairs. The...

Abstract - Beef production in Brazil is based on a great diversity of production systems. Despite the increasing in recent years, productivity is still low, giving space to technological intensification. The present study used special tabulations of Brazilian Census of Agriculture - 2006 to describe the predominant beef cattle systems, with emphasis on technological variables. Factor analysis and clustering techniques were used together, by biome, covering a universe of 124 thousand farms, 94 million heads of cattle and 86 million hectares of pasture. The results highlight the productivity differences among regions and farms, outlining the farm profiles per biome. Such results can be helpful to support research and technologies transfer, as well as public...
