A simple generalization of Wisdom's perturbative method, as originally proposed by Wisdom (1985), is obtained. Any number of resonant cosines can be handled and the method can also accommodate more involved disturbing functions. Averaged trajectories are easily obtained by drawing level curves of the action. Here, the method is first tested for simple models of 3:1 and 2:1 resonant problems. Comparisons with numerical integration and surface-section curves show very good agreements.

Sudden eccentricity increases of asteroidal motion in 3/1 resonance with Jupiter were discovered and explained by J. Wisdom through the occurrence of jumps in the action corresponding to the critical angle (resonant combination of the mean motions). We pursue some aspects of this mechanism, which could be termed relaxation-chaos: that is, an unconventional form of homoclinic behavior arising in perturbed integrable Hamiltonian systems for which the KAM theorem hypothesis do not hold. © 1987.

Wisdom's method is applied to 5 : 2 and 7 : 3 resonances. Comparisons with Yoshikawa's nontruncated model are performed: for moderate values of eccentricity, agreement is good, especially for the 5 : 2 resonance. A clear difference between the 5 : 2 and the 7 : 3 resonances is observed: the former (like the 3 : 1 resonance) can suffer significant variations of eccentricity, even starting from very small values close to 0, while the latter seems to undergo such variations but the minimum eccentricity cannot be less than a value near 0.1. In the 7 : 3 resonance, some chaotic motion trapped in a region of very small eccentricity is possible. This is in contrast with the 5 : 2 commensurability, since chaos in this case seems to be always related to significant variations of eccentricity. Recent calculations performed by Šidlichovskÿ using mapping techniques show agreement with the results presented here. © 1992.

OBJETIVO: Analisar as relações entre agentes comunitários de saúde e os cuidados prestados a idosos. MÉTODOS: Estudo transversal descritivo, com 213 agentes comunitários das 12 unidades básicas de saúde e das 29 unidades de saúde da família de Marília em 2010. Os dados foram coletados por meio de um questionário sociodemográfico, um instrumento de escala de atitudes em relação à velhice (Escala de Neri) e um questionário para avaliar conhecimentos gerontológicos (Questionário Palmore-Neri-Cachioni). Para a análise dos dados, foi utilizado o programa Statistical Package for the Social Sciences versão 16.0 para Windows. RESULTADOS: Predominaram no quadro dos agentes comunitários os adultos jovens, do sexo feminino, casados, escolaridade > 12 anos e inseridos na atividade há mais de seis anos. A maioria dos agentes relatou experiência com grupo de idosos e convivência intradomiciliar com pessoas dessa faixa etária, porém menos da metade referiu capacitação no tema envelhecimento. As avaliações positivas dos agentes quanto às atitudes perante a velhice ocorreram principalmente em aspectos como a sabedoria e generosidade dos idosos, porém foram marcantes as atitudes negativas para lentidão e rigidez. O número de acertos sobre gerontologia foi baixo e esteve diretamente associado às capacitações recebidas pelos agentes. Foram observados estereótipos em relação ao idoso, na medida em que muitos agentes os consideravam insatisfeitos e dependentes. CONCLUSIONES: Mudar as atitudes e melhorar o conhecimento que se tem acerca do envelhecimento é essencial no enfrentamento das demandas advindas dessa fase da vida. Qualificar a formação do agente comunitário de saúde é fundamental no cuidado ao idoso na atenção primária.

Wisdom has recently unveiled a new relativistic effect, called spacetime swimming, where quasirigid free bodies in curved spacetimes can speed up, slow down or deviate their falls by performing local cyclic shape deformations. We show here that for fast enough cycles this effect dominates over a nonrelativistic related one, named here space swinging, where the fall is altered through nonlocal cyclic deformations in Newtonian gravitational fields. We expect, therefore, to clarify the distinction between both effects leaving no room to controversy. Moreover, the leading contribution to the swimming effect predicted by Wisdom is enriched with a higher order term and the whole result is generalized to be applicable in cases where the tripod is in large redshift regions.

Wisdom's perturbative method is applied to the 5:2 and 7:3 resonances. Some comparisons with Yoshikawa's model are performed: for values of eccentricity up to about 0.3-0.4, agreement exists and it is better for 5:2 resonance. A clear difference between the cases 5:2 and 7:3 is observed : the former one, like in the case 3:1, can show significant variations of eccentricity, even starting from very small values, close to zero, while the latter seems to undergo such variations, but with initial eccentricity not less than a value near 0.1.

This study concentrates on the discovery of Japanese Buddhism by Brazilian intellectuals as a group of spiritual practices and as a body of spiritual wisdom. The study has been realized through readings and meetings with Japanese Buddhist monks and/or Japanese immigrants. These intellectuals defend a religious experience based on a universal notion of representations of Japanese Buddhism, which provides them with a non-dualistic philosophical perspective and a unique psychological experience. Through innovative spiritual experiences these intellectuals have broken the tension created within the dispute between secularized science and the Catholic hegemony, both predominant in the intellectual panorama.
