Arrisco comentários sobre a maioridade burguesa da política brasileira, algo reconhecido pelos mais exigentes mentores das políticas neoliberais, não só pela eficiência com que o lulismo faz a mediação entre os interesses do grande capital e os produtos incontornáveis do padrão de acumulação ora imposto: desemprego estrutural, fome e destruição ambiental. Sua maior arte é fazer tudo isso sem provocar qualquer mudança substantiva ao país historicamente marcado pela condição de colonialidade crônica, de desigualdade social endêmica, de sua posição pífia no ranking do mercado de bens de produção, da parca geração de tecnologias, da estabilidade débil da sua economia e política internas.

This study evaluated in vitro the shear bond strength of brackets bonded with xenon plasma arc light, light-emitting diode (LED) and conventional halogen light using different curing times. Brackets were bonded to the buccal surface of 60 human maxillary premolars allocated to five groups. In groups 1 and 2, the resin was cured with the plasma arc for three and six seconds (s), respectively; in groups 3 and 4, the LED was used for five and ten s, respectively; and in group 5, the halogen light was used for 40 s. The specimens were stored in water for 24 hours and subjected to a shear force until bracket failure. The debonding pattern was classified according to the adhesive remnant index (ARI). The results were assessed by Anova and the SNK post-hoc test. No differences were detected among groups 2, 4 and 5, which showed higher averages than groups 1 and 3, which were not different between themselves. The ARI scores showed no differences among the three types of light sources in all times tested. Plasma arc and LED lights can be used with shorter curing times, within certain limits, than conventional halogen light for bonding orthodontic brackets, without decreasing bond strength.

This article aims to narrate and analyze possibilities on aspects of the work developed by the group that composes the Mental Health and Public Health Improvement, using the Wheel Method, created by Gastão W. Campos, in different and diverse articulations and work organization spaces in psychosocial care field, such as Mental Health Forum, work groups related to Regional Collegiate Management (CGRs), with municipal teams to organize mental health network and with newcomer residents to a therapeutic residence It is from these different experiences that it is intended to reflect, discuss and promote a dialogue on the possibilities of the Wheel Method.

The present scenario of the employment market, demands an increasing commitment from employees based on one’s potential to offer the often required skills for companies who desire to hold on to a competitive position in its business segment. Studies about the relationship between commitment and the management polices demonstrates that many organizations are still neglecting the importance of their intellectual resources by applying some measures which result in a dangerous psycho-social environment and a decrease in the employee’s commitment. However, some well established organizations, attentive to signs from the market, are showing evidence of strategically integrated policies that invest in strengthening the relationship with their employees.
