Decision-Making Attitudes in the Beef Chain Industry Innovation Adoption: Brazilian Case Studies

The research objective was to analyze the attitudes of decision-makers in the innovation adoption process in the Brazilian beef chain industry. The study’s approach was qualitative and exploratory, using multiple cases in the beef chain industry. To reach the objective, 17 rural properties in the Brazilian state of Mato Grosso do Sul were investigated. Unstructured interviews were conducted to map the decision-makers’ attitudes regarding the innovation adoption process. Content analysis was performed using the ATLAS.TI software. Findings: The attitudes of the decision makers to evaluate the internal environmental conditions showed the characteristics of informality, slowness, centralization, and conservatism. The factors that affect the innovation adoption were the cost-benefit ratio analysis, the cohesion and connection between what already exists in the organization and the innovative technology, and the uncertainties regarding the return on investment. Originality: The Brazilian Beef Chain has been suffering competition in the domestic and foreign market. Beef Chain can find in innovation a mechanism that allows it to improve its strategic position and thus remain competitive. The findings enabled the proposal of an innovation adoption model based on the attitudes of the decision-makers for the beef chain industry.

Development and validation of a High Performance Liquid Chromatographic method for determination of etoposide in biodegradable polymeric implants

A method using HPLC-UV was developed and validated for the determination of etoposide incorporated into polycaprolactone implants. The method was carried out in isocratic mode using a C18 column (250 x 4.6 mm; 5 µm), at 25 ºC, with acetonitrile and acetic acid 4% (70:30) as mobile phase, a flow rate of 2 mL/min, and UV detection at 285 nm. The method was linear (r² > 0.99) over the range of 5 to 65 µg/mL, precise (RSD < 5%), accurate (recovery of 98.7%), robust, selective regarding excipient of the sample, and had a quantitation limit equal to 1.76 µg/mL. The validated method can be successfully employed for routine quality control analyses

UM OLHAR SOCIOLINGUÍSTICO SOBRE O PORTUGUÊS MOÇAMBICANO: A CONCORDÂNCIA VERBAL DE TERCEIRA PESSOA DO PLURAL | A SOCIOLINGUISTIC LOOK AT MOZAMBICAN PORTUGUESE: THE THIRD PERSON PLURAL VERBAL AGREEMENT

Resumo: Estudo sociolinguístico sobre a concordância verbal de 3a pessoa no Português de Maputo, Moçambique. A partir dos pressupostos da Teoria da Variação e Mudança (WLH, 1968), o objetivo é constatar o estatuto da regra (LABOV, 2003) de marcação de plural na variedade moçambicana. Assim, observaram-se as restrições (extra)linguísticas que condicionam a concordância. Os resultados obtidos por meio do programa GOLDVARB X revelam o comportamento de uma regra semicategórica (96.8% de marcas), índice que deve ser compreendido após análise qualitativa, que aponta a existência de contextos efetivamente variáveis. No entanto, a particularidade da situação multilíngue de Moçambique localizaria a variedade em posição intermediária dentro de um continuum de padrões de concordância da Língua Portuguesa. Abstract: Sociolinguistic study on verbal agreement of 3rd person in the Portuguese of Maputo, Mozambique. From the assumptions of the Theory of Variation and Change (WLH, 1968), the objective is to verify the status of the agreement rule (LABOV, 2003) in the Mozambican variety. Thus, the (extra)linguistic restrictions that constrain the rule were observed. Through the statistical treatment performed in GOLDVARB X, the results obtained reveal the behavior of a semicategorical rule (96.8% of marks), which must be understood after qualitative analysis, that indicates the existence of effectively variable contexts. However, the particularity of Mozambique's multilingual situation would establish an intermediary position for the variety within a continuum of the Portuguese agreement standards. Keywords: Mozambican Portuguese; Sociolinguistics; Multilingualism; Verbal Agreement.

Evaluation of soil resistance to penetration underlying soil load support capacity estimate

A pressão de preconsolidação, apesar das dificuldades inerentes à sua obtenção, representa uma medida útil do estado mecânico do solo para o seu uso, manejo e planejamento de sistemas de mecanização. A estimativa da pressão de preconsolidação, a partir de propriedades do solo facilmente mensuráveis, é, portanto, uma alternativa que pode ser utilizada para contornar as dificuldades. Os objetivos deste trabalho foram: (a) quantificar a pressão de preconsolidação e a resistência do solo à penetração, em laboratório e em campo, para um Latossolo Vermelho-Amarelo, sob pomar de laranja, e (b) estabelecer a relação entre ambos os indicadores físicos. A amostragem e as avaliações foram realizadas em oito dias consecutivos, acompanhando o secamento natural do solo. Houve relação significativa, positiva e linear entre a pressão de preconsolidação e a resistência do solo à penetração, medida no laboratório e no campo. A similaridade das relações entre resistência à penetração, obtida no campo e em laboratório, e a pressão de preconsolidação permitiu afirmar que a capacidade de suporte de carga pode ser adequadamente estimada a partir da resistência de um Latossolo Vermelho-Amarelo distrófico à penetração medida diretamente no campo. __________________________________________________________________________________________ ABSTRACTThe preconsolidation pressure, despite the difficulties inherent to its measurement, provides a useful measure of the soil mechanical state for soil management and the planning of mechanization systems. The estimation of the preconsolidation pressure, based on easily measurable soil physical properties, may be relevant to solve some difficulties. The objectives of this study were: (a) to quantify the preconsolidation pressure and soil resistance to penetration measured in the laboratory and the field for a Haplustox under orange orchard, and (b) to establish relationships between these physical indicators. Sampling and evaluations were carried out on eight consecutive days to observe the natural soil drying. There was a positive, linear, and significant relationship between the preconsolidation pressure and soil resistance to penetration measured in the laboratory as well as in the field. The similarity of the relationships among soil resistance to penetration measured in the laboratory and the field and the preconsolidation pressure allowed affirming that the load support capacity for the Haplustox may be estimated from the soil resistance to penetration measured in the field

Soil compressibility under non-irrigated and irrigated short duration grazing systems

O incremento da produtividade das pastagens tem sido associado ao comportamento à compressão dos solos. Os objetivos deste trabalho foram: quantificar as curvas de compressão e a pressão de preconsolidação em sistemas de pastejo intensivo rotacionado irrigado e não irrigado. Foram coletadas 96 amostras indeformadas de solo em quatro ciclos sucessivos de pastejo instalado com capim Tanzânia (Panicum maximum Jacq.) em um Argissolo Vermelho. Após saturadas com água e equilibradas no potencial (y): -10 kPa, as amostras foram pesadas e submetidas ao ensaio de compressão uniaxial com a aplicação sucessiva e contínua de pressões de 25, 50, 100, 200, 400, 600, 800, 1.000, 1.300 e 1.600 kPa. Os resultados comprovaram a hipótese de que houve diferença na compressibilidade do solo sob os sistemas de pastejo rotacionado intensivo irrigado e não irrigado. A maior compactação inicial verificada no sistema de pastejo rotacionado intensivo irrigado favoreceu o deslocamento das curvas de compressão uniaxial para valores superiores de densidade do solo. A pressão de preconsolidação foi significativamente superior no quarto ciclo de pastejo no sistema de pastejo rotacionado intensivo irrigado em relação ao sistema pastejo rotacionado intensivo não irrigado. ________________________________________________________________________________ ABSTRACTIncrement in pasture productivity has been associated with the understanding of the soil behavior under compression. The objective of this research was to quantify (a) the compression curves and (b) the preconsolidation pressure of the soils under non-irrigated and irrigated short duration grazing systems. Ninety-six undisturbed soil samples were taken from the four successive pasture cycles of Tanzania grass (Panicum maximum Jacq.) in a Hapludalf. The samples were saturated in water and equilibrated at the matrix potential (y): -10 kPa and then were weighed and submitted to an uniaxial compression test, applying the following pressures: 25, 50, 100, 200, 400, 600, 800, 1,000, 1,300, and 1,600 kPa. Results support the hypothesis that there is a difference between the soil compressibility under non-irrigated and irrigated short-duration grazing systems. The higher initial compaction verified in irrigated short-duration grazing system favored the displacement of the uniaxial compression curves for higher bulk density values. The preconsolidation pressure was significantly higher in the fourth pasture cycle under irrigated than under the non-irrigated short duration grazing system
