Abstract: recent research has highlighted the importance of the classroom processes to student performance. accordingly, educational resources, such as the curricula and teacher training, although important, are not considered enough to guarantee student learning. on the other hand, it is increasingly acknowledged that the early elementary school years are crucial for later academic success. this paper presents a synthesis of recent research regarding the elementary classroom processes that are positively associated to student learning, as well as a conceptual model, the classroom assessment scoring system (class; pianta, la paro & hamre, 2008), which organizes teacher-child interactions into three major domains: instructional, organizational and emotional. based on these assumptions, implications for the educational system are discussed.

Abstract: Recientemente, varios investigadores han subrayado la importancia de los procesos interactivos que ocurren en el aula para el rendimiento educativo de los estudiantes. Según investigaciones recientes, los recursos educativos, incluyendo el plan de estudios o la formación de los docentes, aunque importantes, no son suficientes para garantizar el aprendizaje significativo. Además, cada vez más se reconoce que los primeros a os de escolaridad soncruciales para el posterior éxito académico de los estudiantes. Este artículo presenta un resumen de las últimas investigaciones sobre los procesos de sala de clases del primero ciclo de la educación básica que parecen tener un impacto positivo en el aprendizaje de los alumnos. También se presenta un modelo conceptual, o CLASS (Pianta, La Paro & Hamre, 2008) que organiza las interacciones profesor-ni o de acuerdo con tres dimensiones: instrucción, organización y apoyo emocional. Posibles consecuencias para el sistema educativo son también discutidas con base en estos conceptos.
Water Adsorption Isotherms of Amaranth (Amaranthus caudatus) Flour  [PDF]
J. Gabriela Pe?a Balderrama, Sergio C. Carballo Cadima
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.52020

Water sorption isotherms are unique for individual food materials and can be used directly to predict shelf life and determine proper storage conditions. In this context, the aim of this study was to determine the moisture adsorption isotherms of amaranth flour at 15℃, 25℃ and 35℃ in a range of water activity from 0.1 to 0.9. Experimental data were modeled using five equations commonly applied in the foods field. The goodness of the fit for each isotherm model was evaluated through the coefficient of determination, the variance due to error and the confidence interval of the estimated parameters. All models can predict the adsorption isotherms of amaranth flour, but the GAB equation gives a better understanding of the observed sorption behavior. Estimated adsorption monolayer water contents ranged from 6.4 g to 7.2 g of water per 100 g of dry material. It was observed by a weak dependence of water activity with temperature. For ensuring microbiological stability, water content in amaranth flour should not be higher than 13 g of water per 100 g of dry material.

Towards Inhibition of Vif-APOBEC3G Interaction: Which Protein to Target?
Iris Cadima-Couto,Joao Goncalves
Advances in Virology , 2010, DOI: 10.1155/2010/649315
Abstract: APOBEC proteins appeared in the cellular battle against HIV-1 as part of intrinsic cellular immunity. The antiretroviral activity of some of these proteins is overtaken by the action of HIV-1 Viral Infectivity Factor (Vif) protein. Since the discovery of APOBEC3G (A3G) as an antiviral factor, many advances have been made to understand its mechanism of action in the cell and how Vif acts in order to counteract its activity. The mainstream concept is that Vif overcomes the innate antiviral activity of A3G by direct protein binding and promoting its degradation via the cellular ubiquitin/proteasomal pathway. Vif may also inhibit A3G through mechanisms independent of proteasomal degradation. Binding of Vif to A3G is essential for its degradation since disruption of this interaction is predicted to stimulate intracellular antiviral immunity. In this paper we will discuss the different binding partners between both proteins as one of the major challenges for the development of new antiviral drugs. 1. Introduction Vif is a 23-kDa cytoplasmic protein that is expressed from a partially spliced mRNA in Rev-dependent manner during the late phase of HIV-1 replication. The human immunodeficiency virus type 1 (HIV-1) Vif protein is essential for virus replication in primary lymphoid and myeloid cells, but is dispensable for efficient replication in several transformed T-cell lines as well as in nonlymphoid cell lines such as HeLa and 293T [1–3]. Cells that are unable to support the replication of Vif-defective HIV-1 (HIV-1 Vif) have been termed “nonpermissive,” while cells that can sustain HIV-1 Vif replication are termed “permissive.” These findings were made over 15 years ago but the molecular mechanisms underlying this cell-specific difference were maintained a mystery until 1998. The observation that heterokaryons formed by fusion of nonpermissive and permissive cells exhibit the nonpermissive phenotype [4, 5] led to the hypothesis that nonpermissive cells express an inhibitor of HIV-1 replication that is blocked by the viral Vif protein. Later, in 2002, Sheehy et al. reported the identification of the apolipoprotein B mRNA-editing enzyme-catalytic polypeptide-like 3G (APOBEC3G) as the HIV-1 replication inhibitor [6]. A3G is located in the cytoplasm of the cell and has been shown to be an exclusive DNA mutator [7]. A3G exists either as enzymatically active low-molecular-mass (LMM) forms consistent with enzyme monomers or dimers, or as an enzymatically inactive high-molecular-mass (HMM) ribonucleoprotein complex larger than 2?MDa [8]. LMM A3G is found in resting
An exploratory study of the relationship between counterfeiting and culture
Santos,J. Freitas; Ribeiro,J. Cadima;
Tékhne - Revista de Estudos Politécnicos , 2006,
Abstract: international counterfeiting affects adversely producers, consumers and domestic economies. some attempts have been made in the last years by international organisations (european union, world trade organisation) to deal with this complex problem. though some success has been achieved, the number of seizures of counterfeited goods detected in the external borders of eu has increased. this study examines the impact of hofstede?s cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance) on the attraction of international counterfeiting to european union member countries. a cultural profile of a counterfeiter country is one in which there is low power distance, low uncertainty avoidance, and low individualism.
Sustainable use of endogenous touristic resources of rural areas: two portuguese case studies
Cruz Vareiro, Laurentina,Ribeiro, J. Cadima
PASOS : Revista de Turismo y Patrimonio Cultural , 2007,
Abstract: Empirical evidence shows that tourism can give a real contribution to regional development and, in the case of certain remote and economic lagged territories, it is one of the best sectors to achieve this goal. This role of tourism as to do, namely, with the possibility of taking profit from the endogenous resources endowment of these territories. Meanwhile, the opportunities are not the same for each region and it is easy to understand that, considering the resources available, not every one has the choice to base its development strategy in the tourism sector. On the other hand, sustainable development depends, both, on conservation and valorisation of the resources potential and on diversification of tourism activities and products, no matter the agents or policy options are. Based on empirical research carried out in Caminha and Paredes de Coura portuguese municipalities, and in what Tourism in Rural Areas (TRA) is concerned, we present in this paper a preliminary evaluation of the social and economic impacts of the tourism strategies followed. We also aim to extract some policy implications in order to better design future approaches to this issue of taking profit from resources endowment of territories. The starting point is the one of tourism based on quality, which serves the interests of local populations

Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.23054
Abstract: In this note, we start to claim that established marriages can be heavilydestabilized when the population of existing couples is enriched by thearrival of new candidates to marriage. Afterwards, we discuss briefly howstability concepts can be extended to account for entry and exit phenomenaaffecting the composition of the marriage market.
Metáforas e imagens dos formadores de professores na área da informática aplicada à educa??o
Peixoto, Joana;
Educa??o & Sociedade , 2007, DOI: 10.1590/S0101-73302007000400011
Abstract: the focus of this research is the gap between the formation of educational computing (ec) teachers and their further experience. the main hypothesis is that, among ec teacher formers, there is a certain representation of the educational model and a conception on the beneficial aspects of digital technologies that would be automatically transferred to the future teachers' practice. an investigation was carried out with the 21 teachers of the discipline "computing and education" at the catholic university of goiás, with the use of techniques of free word association, semi-structured interviews and focus groups. the nucleus of the identified representations shows the computer as a generator of educational changes, and educational computing as the agent of pedagogical changes. this analogy becomes an important reference that shapes formers' discourse by means of metaphors which constitute their imagination.
