Provas de carga estática com carregamento lateral em estacas escavadas hélice contínua e cravadas metálicas em areia

An experimental study has been conducted to investigate the behavior of continuous flight auger (cfa) bored piles and metalic driven H-section piles under lateral loading in cohesionless soils. The piles were tested in two different areas at the same site. Both areas consisted of a 3-m thick compacted superficial fill of pure fine sand, underlain by layers of naturally occurring pure fine-thick sand. Fills are differentiated by the relative densities which were compressed, 45% e 70%, respectively. Each area received one identical pair of cfa piles and two identical pairs of H-piles. A static lateral loading test was performed in each pair of piles. In this work, the pile load test results are reported and interpreted. The horizontal coefficient of subgrade reaction was determined from the results of the loading tests and compared with values determined by correlations based on penetration resistance index of SPT tests (NSPT). p-y formulations describing the static behavior of the piles were applied to the problem under evaluation. Back Analyses were made through theoretical and experimental p-y curves for obtaining input parameters for the analytic models, among which the coefficient of horizontal reaction. The soil pile system horizontal loading at rupture was determined by the theoretical methods and the results were compared with the experimental results, checking its validity

Aspectos do cuidado cooperativo em dois grupos de Callithrix jacchus selvagens

The Callitrichidae family presents cooperative breeding, where breeders and non breeders take care of the offspring. The aspects of care analyzed in this study were infant carrying, supervision, proximity and food transfer. Three sets of infants from two wild groups of Callithrix jacchus were studied in the environments of Caatinga (Assu group) and Atlantic Forest (Jundiaí group). The methods used in the study were instantaneous focal sampling (infant carrying, supervision and proximity) and continuous focal sampling (food transfer). In the two sets observed in Assu group, the father carried and transferred food to infants more than the rest of the group. The biggest contribution in supervision was from the father and from another adult male. The members that remained in proximity to the infants in both groups were the younger in the groups (juveniles and sub-adults). In the Jundiaí group, the father and the adult male helper of the group were the main caregivers; one of the sub-adult females was responsible for supervision of the infants. With the disappearance of the reproductive male and one of the sub-adults females in 3º month of infants life, the care was redistributed and the only adult male left in the group was the animal that contributed more in provisioning of the infant. In the Assu group, there were adult females in its composition which were involved in agonistic interactions with breeders and adult males, and seemed to influence their low participation in care. Food transfer initiates early in the development of the infants, as a way to encourage nutritional independence. Different types of food transfer (active food transfer, food steal, food steal attempt, passive food transfer and food handling) were observed in the study and frequency of each one varied with developmental phase and tolerance by the members. One relevant data of the study was the presence of active food transfer in Assu group, since in literature there are very few registers of this type of transfer for this species. It is important that groups from distinct environments and composition be studied for a better understanding of the dynamics of infants development

Relações interorganizacionais e eficiência coletiva: um estudo de caso no arranjo produtivo local de confecções do agreste pernambucano

This work is a study in the Local Productive Arrangement of confections from Agreste of Pernambuco, as a relevant sector in economic and social aspect. This research has as central aim to understand how the inter-organizational relations influence the collective efficiency of arrangement. The theoretical framework employed highlights the approaches that deal with the benefits of business agglomeration for the develop­ment of firms and regions. It has discussed the approach of small and medium enter­ prises and industrial districts (SCHMITZ, 1997), which introduce the concept of col­ lective efficiency, explaining that only those externalities explained by Marshall (1996) are not sufficient to explain the competitive advantage of enterprises, expand­ing the idea that organizations achieve competitive advantage not acting alone. To examine the influences of relations in the collective efficiency, it has been taken as analytical perspective theory of social networks (GRANOVETTER, 1973, 1985; BURT, 1992; UZZI, 1997) because it has believe that this approach provides subsi­ dies for a structural analysis of social relationships in face the behavior of human ac­tion. By examining the organizations in a social network, you should understand the reason of this establishment of the relationship, their benefits, and as the information flow takes place and density of links between the actors (Powell; SMITH-DOERR, 1994). As for the methods, this study is characterized as a case study, in according to the purposed objectives, in addition to qualitative method. Also, due to recovering of the historical milestones of the arrangement, it is used a sectional approach with longitudinal perspective (VIEIRA, 2004). The primary and secondary data were used in order to understand the evolutionary process of the sector and their inter-actors re­ lationships in the arrangement for the promotion of development, for both, was used the contend and documentary analysis technique, respectively (DELLAGNELO ; SIL­VA, 2005). The approach of social networks has permitted understand that social re­lationships may extend the collective efficiency of the arrangement, and therefore need to develop policies that encourage the legalization of informal companies in ar­rangement, by showing up themselves representative. Thus, the relations estab­ lished in LPA of confections from Agreste of Pernambuco need for more effective mechanisms to broaden the collective efficiency. Therefore, this way as take place has directly benefited only a group of companies that are linked in some way the sup­portive institutions. So we can conclude that the inter-actor relations have limited the collective efficiency of LPA, being stimulated by the institutions in support only to groups of entrepreneurs, even those that produce external relations for all clustered companies

Corporeidade e educação: sinfonia de saberes na educação musical

This study investigates the implications between the musical theory and pedagogical practice based on a study that questions the reasons why some students feel incapable of learning the music language, as well as, if the musical codes are truly so difficult to be apprehended by them. To answer these questions takes itself as reference, the classes I have minister while teaching the disciplines: Music Workshop and Music Language I in the Art Department, Scenic Art Course at the Federal University of Rio Grande do Norte. I have searched the knowledge that constitutes the teacher formation based on the union between the pedagogical efficiency and sensibility, searching in the Corporality the theoretical port for my investigation. This way, advocating is a methodological principle for musical education originated from the experience of knowledge: creating, playing, feeling, thinking, and the interaction among them, conducting the students not only to music learning, but to a process of human formation. It adopts itself as methodological resource, amongst the qualitative methods, some of the techniques that are associated with the ethnographic research, for having as its main objective, to study the meaning of the actions and events of the investigated group. The analysis of the data leads to the conclusion that when the teacher displays his or her pedagogical knowledge in an environment constructed with affectivity, in a playful and pleasant form, the assimilation and construction of the musical concepts happen naturally and efficiently, surpassing the taboo that music learning is only possible to the especially well endowed people for music. Very aware that the scientific debate is important for the strengthening of formative programs involved in the growth and consolidation of the musical teaching and learning area, it is expected to promote this research discussions and reflections in the general educational field with this research, as well as, to contribute significantly to the specific growth of musical education

Praxiologia, representação social de menopausa e práticas educativas de enfermeiras na estratégia saúde da família

This research, whose theme is related to climacteric, aims to know the social representation of menopause developed by the nurses working for Estratégia Saúde da Família (Family Health Strategy) in João Pessoa PB, as well as identifying its structure and verifying the way it interferes with the assistance and educational practices to the climacterial user. In the theoretical level, it is based on a model that articulates the social representations theory, the central nucleus complementary theory and the central concepts of Pierre Bourdieu s praxiology: habitus, cultural capital, social field and symbolic power. A hundred and forty-seven female nurses who work for Estratégia Saúde da Família (Family Health Strategy) in João Pessoa (PB) took part in this research, and the data collection period was from February 2008 to March 2009. As to the methods and techniques, we used the method to determine the central nucleus based on the free association of words, a questionnaire to identify certain regularities that constitute the nurses habitus, and the semi-structured interview to explore opinions and attitudes when facing assistance situations and educational practices and to collect other relevant information. The data analysis was developed, when referring to the free associations, with the help of the EVOC software, which is a group of articulated programs which carry out the statistical analysis of the evocations and the identification of the possible elements of both the central nucleus and the peripheral system of the social representation. As to the questionnaire, we used the descriptive statistical analysis and the analysis of correlation between the variables. The interviews were submitted to a categorical analysis of the content. The EVOC result indicated that the cognition hormone was the only element of the central nucleus of the social representation of menopause. Due to its symbolic value and structuring power, this central nucleus ensures the strict and, at the same time, flexible character of the representational content. The analysis of the social advancement, of some fundamental features of the group habitus, as well as the analysis of its insertion in the health field and of the attitudinal opinions and dispositions concerning the assistance given to the climacterial user, and the analysis of the pedagogical dimension of this assistance, all these analyses lead to the conclusion that the nurses who took part in this research share a social representation of the menopause resulting from the association of different technical and scientific knowledge. These derive from the biomedical pattern as well as from hegemonic values which disqualify old age and overvalue youth, from pedagogical conceptions arising from patterns that are presently regarded as authoritative and old-fashioned and from cultural references (responsible for the semantic variations concerning the central nucleus) which are specific to the subgroups the nurses belong to. This research enables the creation of opportunities for discussion between active nurses working for Estratégia Saúde da Família, and the nurses who are teachers at institutions of higher education, aiming at linking theory to practice, so that they can find ways of thinking about the climacteric and working, in a more comprehensive way, with users who are experiencing this stage of life
