Este estudo analisou 742 eventos envolvendo comportamento de cuidado entre crianças abrigadas com e sem irmão na mesma instituição. Foram aplicados testes estatísticos para avaliação intergrupal na comparação entre os sujeitos focais. As crianças com irmão manifestaram a maior proporção desses comportamentos e foram dirigidos principalmente a parceiros não-Irmãos (companheiros de dormitório) ou adultos (cuidadores). O estudo revelou ainda que o comportamento Brincar de cuidar foi mais freqüente no grupo de crianças Com Irmão na instituição enquanto que entre os participantes Sem Irmão predominou Estabelecer contato afetuoso e comportamentos direcionados mais a adultos do que aos pares. Conclui-se que o comportamento de cuidado está presente entre irmãos, mas assume formas particulares em razão da complexa dinâmica social que caracteriza o ambiente pesquisado.

Seeds Tabebuia aurea (syn. Handroanthus aureus Mattos), The seeds of Tabebuia aurea (syn. Handroanthus Mattos aureus), have low metabolic rates, which favors their storage conditions and freezing temperatures when stored at room temperature, there is a progressive decline in viability. Therefore, this study aims to determine the viability and longevity of seeds of Tabebuia aurea subjected to different storage methods. There were used 6100 seeds. In 2400 seeds were stored refrigerator, which in 1200 placed in transparent plastic bag and 1200 in Kraft paper bags. 3600 Other seeds were placed in room temperature and 1200 seeds in clear plastic bag, 1200 in Kraft paper bags and tray open in 1200. For each treatment, four replicates of 25 seeds for 12 months, with design was completely randomized. The average germination, normal seedlings and speed germination index were transformed into (x+1)(-1/2). The data were submitted to ANOVA and means compared by Tukey test at 5%. Also regressions polynomials were modeled for the variables study in function of the periods of storage of the seeds. The seeds stored in the refrigerator at 13 C maintained a high germination rate and normal seedling germination rate during the 360 days of evaluation. The method suitable for the seed storage of Tabebuia aurea is in the refrigerator at 13 degrees C, both in plastic and paper.

We consider a class of functional differential equations subject to perturbations, which vary in time, and we study the exponential stability of solutions of these equations using the theory of generalized ordinary differential equations and Lyapunov functionals. We introduce the concept of variational exponential stability for generalized ordinary differential equations and we develop the theory in this direction by establishing conditions for the trivial solutions of generalized ordinary differential equations to be exponentially stable. Then, we apply the results to get corresponding ones for impulsive functional differential equations. We also present an example of a delay differential equation with Perron integrable right-hand side where we apply our result.

From a theoretical foundation favorable to industrial policies, this paper intends to show the main policies followed by Ireland since the 1950s, with a special emphasis on those directed to Science, Technology and Innovation (S,T&I), FDI and high tech sectors, like software and biotechnology. We compare these policies with those used in Brazil, in a similar period, in order to have some hints for virtual transformations of current Brazilian policies. We conclude that the compromise of the State with the direction of the development and the continu-ity of industrial policies is very important to a solid building of comparative advantages in technologically dynamic sectors.

This study aims to discuss, by assuming the perspective of the Discourse Analysis, the social and cultural implications of the process of teaching Portuguese to foreigners in the virtual context of Teletandem. It also intends to evaluate the levels of Critical Language Awareness presented by the participants, in relation to the linguistic, discursive and social dimensions of the analysis. The data were collected in 2011 in interactions between students from Unesp/Assis and students from North-American universities. The research has been guided by the following questions: (a) how social and historical changes are reflected in language uses; (b) how these implications appear in the context of Teletandem; (c) how is it possible to evaluate the levels of Critical Language Awareness between the participants related to the social dimension of the discourse.

An ability to detect and quantify protein molecules, harbingers of specific pathologies, potentially underpins both early disease diagnosis and an assessment of treatment efficacy. However, the specific detection of a particular protein biomarker in a complex environment is by no means an easy task and requires a progressive improvement in sensor technology. The high surface area, volume, electrical conductance, atomic level thickness and apparent biocompatibility of graphene makes it potentially an exceedingly powerful transducer of biorecognition events; the demands of its application in biosensing, and progress to date are reviewed herein.
