The Individual

Population change and environmental degradation have become two of the most pressing issues for sustainable development in the contemporary world, while the effect of population aging on pro-environmental behavior remains controversial. In this paper, we examine the effects of individual and population aging on pro-environmental behavior through multilevel analyses of cross-national data from 31 countries. Hierarchical linear models with random intercepts are employed to analyze the data. The findings reveal a positive relationship between aging and pro-environmental behavior. At the individual level, older people are more likely to participate in environmental behavior (b = 0.052, p < 0.001), and at the national level, living in a country with a greater share of older persons encourages individuals to behave sustainably (b = 0.023, p < 0.01). We also found that the elderly are more environmentally active in an aging society. The findings imply that the longevity of human beings may offer opportunities for the improvement of the natural environment.

Plasma norepinephrine (NE), epinephrine (E), and neuropeptide Y (NPY) were evaluated in seven young (median age 29 yr, range 21–31) and seven elderly (median age 61 yr, range 51–72) healthy subjects. They were all nonsmokers and had never smoked. Basal values and the initial increase in plasma NE and E during exercise at 75% of maximal work load were identical in the two groups. After 5 min of exercise at this load, plasma NE and E remained constant in the elderly but were still increasing in the young subjects. Plasma NE and E increased to significantly higher values after 15 min in the young subjects: 1.68 +/- 0.18 vs. 0.92 +/- 0.11 ng/ml (NE) and 0.136 +/- 0.012 vs. 0.061 +/- 0.013 ng/ml (E). Basal plasma NPY was highest at rest and increased only during exercise in the young subjects. Our results demonstrate that in nonsmokers aging is not associated with increased plasma NE levels. The blood pressure response to exercise was the same in both groups, suggesting that the increase in the sympathetic activity was adequate in the elderly. Alternatively, the higher increase in sympathetic activity in the young subjects may be attributed to their higher work capacity.

Nowadays, death, illness, and suffering are experienced as danger: a threat to one’s own physical, psychological and social identity. And what accompanies all these, particularly paralizing from a spiritual perspective, is fear; the dread that all is lost, that things cannot be controlled by means of medicine, only to reach the greatest angst: the fear of death. And, in this respect, we can say that pain, suffering and the fear of death make up the anthropological foundation of the most profound religious concept of life, in the sense that these realities show man his limitations, his finite build, that of a creature, and, consequently, determine him look beyond his limitations. The fear of death brought about angst, anxiety, passion, hatred, and despair in man’s life. His need to escape death made him look for even more material elements to render him oblivious to it. The solution against despair is God: faith vanquishes despair because, by faith, man acknowledges his dependence on God, but turning within himself, at the same time.

In the contemporary world, the progressive aging of the population is both a major achievement and a huge challenge for developing countries, especially when it relates to public policies for the elderly. The scenario is particularly worrying in peri-urban spaces, which we call “territories of fragility”, in which multiple deficiencies overlap — basic sanitation, housing, accessibility, education and health — those aspects coupled with the disruption of community ties, negatively impact the aging process. In this article, we analyze the previously presented scenario through the results of a continued education project that had as students 420 professionals that currently work in the Secretariat of Social Assistance of the city of São Paulo (Brazil). The aim of the project was the improvement of the work in the social assistance services network, especially the ones that are a part of the basic social protection, aimed at the most vulnerable part of the population. The use of professional-centered training methodology takes into account what happens in the field, it is based on daily problems, on the perception of skills and abilities, on the challenges and opportunities given by occupied spaces, in a dialogical and critical perspective. In other words, the result was a collection of 420 “first-hand” narratives that unveils a reality that is the opposite of what was expected. For the enrichment of the reflection, we present the commitments to this educational process — through the narratives of teachers and supervisors — in the work of recognizing the action field, the difficulties and achievements in the implementation of the project, and in practice with the groups. Content analysis indicates, in the complexity of the narrative, how all individuals that were a part of the project overcame life-work challenges and articulated knowledge about the aging process in territories of fragility.

Religious identity as one of the types of identity has a close relationship with social identity and encompasses the expectations of one's religion in the individual and social domain. This is why scholars have attempted to theorize the presence of religion in the contemporary world, and since decades ago, various terms have been used to explain the emergence of religion, and some have spoken of the post-secular era. The concept of post-secularism, which has been followed by secularism, has justified the possibility of religion being present in public culture, but with the precondition that presence in social space should not extend to the political sphere and social structures.

Surface Changes

Ultrastructural changes have been shown to occur in the urinary bladder epithelium (urothelium) during the life span of humans. With increasing age, the luminal surface becomes more flexible and develops simple microvilli-like processes. Furthermore, the specialised asymmetric structure of the luminal plasma membrane is relatively more prominent in the young than in the elderly. The nature of the changes at the luminal surface is now explored by lectin-mediated adsorption visualised by scanning electron microscopy (SEM).Samples of young adult (21-31 y old) and elderly (58-82 y old) urothelia were fixed in buffered 2% glutaraldehyde for 10 m and washed with phosphate buffered saline (PBS) containing Ca++ and Mg++ at room temperature. They were incubated overnight at 4°C in 0.1 M ammonium chloride in PBS to block any remaining aldehyde groups. The samples were then allowed to stand in PBS at 37°C for 2 h before incubation at 37°C for 30 m with lectins. The lectins used were concanavalin A (Con A), wheat germ agglutinin (WGA), phytohaemagglutinin (PHA) and pokeweed mitogen (PWM) at a concentration of 500 mg/ml in PBS at pH 7.A.
