Equal Couples in Equal Houses : Cultural perspectives on Swedish solar and bio-pellet heating design

Knowing how to design a heating system that will work mechanically is quite different from knowling how to design a system that users perceive as responsive to their domestic practices and values. In this chapter, social anthropologist Henning argues that the challenge for designers involved in the development or marketing of green buildings with heating systems that are based on renewable sources of energy is to see things from the perspective of those who are supposed to live in these buildings. The chapter focuses on three culture-specific aspects of Swedish households and single-family houses: perceptions of house and home, of private and public space, and of male and female space. Through these three angles, some clues are given as to how design, performance and location of solar and bio-pellet heating systems could be made to resonate with predominant experiences, habits and ways of thinking among both men and women.

Therapeutic Discourse and the American Public Philosophy: On American Liberalism's Troubled Relationship with Psychology

I explore the main currents of postwar American liberalism. One, sociological, emerged in response to the danger of mass movements. Articulated primarily by political sociologists and psychologists and ascendant from the mid-fifties till the mid-seventies, it heralded the "end of ideology." It emphasized stability, elitism, positive science and pluralism; it recast normatively sound politics as logrolling and hard bargaining. I argue that these normative features, attractive when considered in isolation, taken together led to a vicious ad hominem style in accounting for views outside the postwar consensus. It used pseudo-scientific literature in labeling populists, Progressives, Taft conservatives, Goldwaterites, the New Left and others "pathological," viz. mentally ill. Hence, "therapeutic discourse." I argue that philosophical liberalism, which reasserts the role of political theory in working out norms and adjudicating disagreement, is a more profitable way of thinking about and defending from critics liberalism. I take the philosopher John Rawls as the tradition's modern representative. This inquiry is important because the themes of sociological liberalism are making a comeback in American public discourse, and with them perhaps the baggage of therapeutic discourse. I present a cautionary tale.

Socio-cultural Degeneration and State Patronage of the Arts: Mapplethorpe, Cultural Crisis, and the NEA

The goal of this paper is to investigate how the Untied States federal government, specifically through the National Endowment for the Arts, or NEA, has acted in the position of an arts patron in the past few decades. Specifically, this paper will focus on the past decade and a half since the 'arts crisis' of the late 1980s and the social and political backlash against the art community in the 1990s, which was only against ‘offensive’ art that was seen as morally and culturally corruptive. I explore the political, social, and economic forms the backlash took, particularly rooted in a perceived fear of degenerative arts as a corruption of and a catalyst for the eventual collapse of American culture and values. Additionally, I analyse the role the federal government played in ‘ameliorating’ the situation. I investigate how state arts patronage has affected and continues to affect both the concepts behind and the manifestations of art, as well as who is encouraged, sanctioned, or neglected in the production of art. To accomplish this, I explore how and why the federal government employs the arts to define and redefine morality and culture, and how does it express/allow the expressions of these through art.

Influência da mudança organizacional na percepção dos papéis desempenhados no trabalho: o caso do arsenal de Marinha do Rio de Janeiro

O Objetivo desta pesquisa é analisar a influência da mudança organizacional sofrida pelo Arsenal de Marinha do Rio de Janeiro (AMRJ) sobre a percepção em relação aos papéis desempenhados pelos seus servidores, dos níveis gerencial e operacional, no que tange a valores e crenças sobre o seu trabalho. Esta pesquisa constitui um estudo de caso, e se deu por meio de pesquisa de campo, de cunho qualitativo, e por isso, os dados foram analisados de forma descritivo-interpretativa sobre a avaliação documental e do seu conteúdo. Os dados primários foram obtidos a partir de análise de documentos, tais como relatórios, normas, publicações e regulamentos internos; e os dados secundários foram provenientes de entrevistas semiestruturadas; e possibilitaram averiguar as categorias analíticas envolvidas na pesquisa. As amostras para as entrevistas foram selecionadas de populações, dentro do AMRJ que fossem semelhantes ou equivalentes a populações de indústrias privadas e os sujeitos das mesmas, que, igualmente, tivessem equivalência funcional em outras indústrias ou empresas a fim de serem representativas para a composição do conteúdo da pesquisa. Os dados coletados permitiram concluir que o AMRJ ainda se encontra em processo de acomodação à mudança que se iniciou, e que o trabalho passou a ser mais gratificante para o nível gerencial, assumindo uma perspectiva de desafio e crescimento profissional a partir de um novo enfoque dado a ele, porém, para o nível operacional, devido a uma motivação decrescente e a interesses frustrados, sua percepção considera o trabalho como menos gratificante que o outro nível, apesar do sentimento positivo que tem pela instituição. Concluiu-se, também, que as mudanças são necessárias, apesar das dificuldades inerentes a ela, e influenciam a percepção das pessoas, mas podem ficar comprometidas caso não seja levado em conta que deve haver uma equivalência na distribuição, entre todos os níveis, dos benefícios que podem favorecê-la.

Family visitors and companions of hospitalized elderly and adults: analysis of the experience from the perspective of the nursing working process

Trata-se de estudo qualitativo, utilizando-se como referencial metodológico a Grounded Theory e como referencial teórico o Processo de Trabalho em Enfermagem, para compreender o papel assumido pelo enfermeiro perante as normas e rotinas hospitalares, relativas aos familiares visitantes e acompanhantes de adultos e idosos internados em um Hospital Universitário. A análise dos dados permitiu a identificação do tema: definindo-se a modalidade de apoio familiar durante a hospitalização, que reúne duas categorias principais: tornando-se familiar visitante e tornando-se familiar acompanhante. Por meio da análise, pôde-se aprofundar a compreensão do quanto as regras estabelecidas, com o objetivo de disciplinar e tornar eficiente o trabalho desenvolvido no hospital, podem explicitar o desprovimento de autonomia no processo de trabalho, para modificar as relações nesse contexto e o quanto a apropriação do familiar como parte da equipe de saúde, está distante de ser pensada no concreto das instituições.

Metabolic syndrome and its associated risk factors in Brazilian postmenopausal women

Objective To evaluate the prevalence of metabolic syndrome (MetS) and its associated risk factors in Brazilian postmenopausal women.Methods In this cross-sectional study, a total of 368 postmenopausal women, aged 40-75 years, seeking health care at a public outpatient center in Southeastern Brazil, were included. According to the US National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines, MetS was diagnosed in subjects with three or more of the following: waist circumference >= 88 cm, blood pressure >= 130/85 mHg, triglycerides >= 150 mg/dl, high density lipoprotein cholesterol <50 mg/dl and glucose >= 110 mg/dl. Data on past medical history, tobacco use, anthropometric indicators, and values of C-reactive protein (CRP) were collected. Multivariate analysis, using a logistic regression model (odds ratio, OR) was used to evaluate the influence of various simultaneous MetS risk factors.Results The prevalence of having at least three, four and five MetS diagnostic criteria were met in 39.6%, 16.8% and 3.8% of the cases, respectively. The most prevalent risk factor was abdominal obesity, affecting 62.5% of women. The risk of MetS increased with a personal history of diabetes (OR 5.95, 95% confidence interval (CI) 2.82-12.54), hypertension (OR 4.52, 95% CI 2.89-7.08), cardiovascular disease (OR 2.16, 95% CI 1.18-3.94) and high CRP (>1 mg/dl) (OR 3.35, 95% CI 1.65-6.79). Plasma CRP levels increased with the number of MetS components present. Age, time since menopause and smoking had no influence, while hormone therapy reduced MetS risk (OR 0.64, 95% CI 0.42-0.97).Conclusion Metabolic syndrome was highly prevalent among Brazilian postmenopausal women seeking gynecologic health care. Abdominal obesity, diabetes, hypertension and high CRP were strong MetS predictors and hormone therapy appeared to play a protective role for this condition.

Influence of Osteopenia in Autogenous Bone Graft Healing With or Without Expanded Polytetrafluoroethylene Membranes: Histologic and Histomorphometric Study in Rats

Purpose: The aim of this study was to quantitatively evaluate and qualitatively describe autogenous bone graft healing with or without an expanded polytetrafluoroethylene (e-PTFE) membrane in ovariectornized rats. Materials and Methods: Eighty Wistar rats, weighing approximately 300 g each, were used. A graft was obtained from the parietal bone and fixed to the sidewall of each animal's left mandibular ramus. The animals were randomly divided into four experimental groups (n = 20 in each group): group 1, sham operated and autogenous bone graft only- group 2, sham operated and autogenous bone graft covered by e-PTFE membrane; group 3, ovariectornized (OVX) and autogenous bone graft only- group 4, OVX and autogenous bone graft covered by e-PTFE membrane. The animals were sacrificed at five different time points: immediately after grafting or at 7, 21, 45, or 60 days after grafting. Histologic examination and morphometric measurement of the sections were performed, and values were submitted to statistical analyses. Results: Both groups (sham and OVX) experienced loss of the original graft volume when it was not covered by the membrane, whereas use of the membrane resulted in additional bone formation beyond the edges of the graft and under the membrane. Histologic analysis showed integration of the grafts in all animals, although a larger number of marrow spaces was found in OVX groups. Conclusions: Association of bone graft with an e-PTFE membrane resulted in maintenance of its original volume as well as formation of new bone that filled the space under the membrane. Osteopenia did not influence bone graft repair, regardless of whether or not it was associated with e-PTFE membrane, but descriptive histologic analysis showed larger numbers of marrow spaces in the bone graft and receptor bed and formation of new bone in the OVX animals.

Fluorescence study of the interaction between metal ions and methyl methacrylate methacrylic acid copolymers in aqueous solutions: thallium(I), calcium(II), and terbium(III)

The binding of the cations thallium(I), calcium(II) and terbium(III) to methyl methacrylate-methacrylic acid copolymers with different fractions of acid groups (x) has been studied in aqueous solution at, various pH values using the fluorescence of covalently bonded 9-vinyl anthracene as a probe. In all cases, the extent of binding increases as a function of the charge of the polymer with either increasing fraction of carboxylic acids or of pH. However, differences are observed in the behavior of the three cations, With Tl(I), quenching of the anthracene group fluorescence is observed. indicating that the thallium(I) approaches the probe and suggesting that the alkylanthracene is probably in a relatively polar region. Binding constants have been determined from anthracene quenching data and from studies with the fluorescent-probe sodium pyrenetetrasulfonate, Good agreement is obtained between the two methods, and values for the binding constants increase from 250 to 950 M-1 as x increases from 0.39 to 1. It is suggested that the cation is held in the polyelectrolyte domain, partly by Debye-Huckel effects and partly by more specific interactions. Stronger binding is found with calcium(II) and terbium(III), and in this case increases in fluorescence intensity are observed on complexation due to the anthracene group being in a more hydrophobic region, probably as a result of conformational changes in the polymer chain. In the former case the stoichiometry of the interaction was determined from the fluorescence data to involve two carboxylate groups bound per calcium. Association constants were found using murexide as an indicator of free calcium to vary from 8400 to 37 000 M-1 as x increases from 0.39 to 1. It is suggested that in this case specific calcium(II)-carboxylate interactions contribute to the binding. With terbium(III), a greater increase in the probe fluorescence intensity was observed than with calcium, and it is suggested that the interaction with the polymer is even stronger, leading to a more pronounced conformational change in the polymer. It is proposed that the terbium(III) interacts with sis carboxylic groups on the polymer chain, with three being coordinated and three attracted by electrostatic interactions.

Environmental education and the health risk question: how do we educate the educators working with this theme?

Our society is presently seeing a trend of continuous increase of risk with severe consequences, especially those linked to environmental aspects. It has obligated us to reflect on this production and its effects, either positive or negative, and, after a long reflection, to think about the adopted model of civilization and the possibilities of changing such a model. The educational institution is among the social departments responsible for this revision process, since it represents one possibility to promote a more critical vision from society, providing it with tools needed for a more responsible action. However, schools are dominated by a traditional work, which does not allow for enough and proper attention to these relevant and current questions, and which involve a critical analysis of the conceptions and values established by our civilization, resulting in the present patterns of science-technology-society relations and their influence on the environment and health. Several research works have indicated a diversity of barriers that obstruct this necessary change. Since formal education plays an important role in the education of society for this theme, in this paper the possibilities and difficulty dealing with this problem are discussed, focusing on the question of teacher education, based on investigations related to teacher education programs for environmental education. The data collected show the urgency for introducing this theme in teacher training programs, taking into account the fact that educators have their own conceptions, values and attitudes that should be considered in these programs.

Comparison of artificial and natural, new and reused, brackish water for the larviculture of the freshwater prawn Macrobrachium rosenbergii in a recirculating system

Differences in culture duration, metamorphosis rate and the productivity in hatchery culture of M. rosenbergii using a closed system with natural and artificial brackish water were evaluated. Reuse of brackish water in more than one hatchery cycle was also evaluated. Natural and artificial brackish water constituted the two tested treatments, which were distributed in four independent recirculating systems (tank and respective biofilter). Four batches of cultures were conducted and the 2nd and 4th reused the water from the 1st and 3rd, respectively. Mean duration of the hatchery period was 28 d in natural brackish water and 31 d in artificial brackish water. The metamorphosis rate and the average productivity for the natural brackish water treatment were 74% and 60 postlarvae/ L. respectively, and values obtained with artificial brackish water were 55% and 44 postlarvae/L. The successful hatchery culture of M. rosenbergii in this specific artificial brackish water suggests its potential use in enterprises located far from the coast. Brackish water can be used in two consecutive cultures without a negative effect on productivity.

Blood parameters of chicks from eggs injected with ascorbic acid and subjected to thermal stress

This study was aimed to verify if chicks from eggs injected with ascorbic acid and subjected to thermal stress would have higher immunity than chicks from incubation at thermoneutrality without injection of ascorbic acid. The parameters evaluated were temperature on oxygen saturation in hemoglobin, glucose, number of erythrocytes, hematocrit rate and number of hemoglobins of newly hatched male chicks, hatched from eggs injected with ascorbic acid (AA) and subjected to thermal stress during incubation. The experimental design was completely randomized in factorial scheme 5 (application levels of ascorbic acid) x 2 (incubation temperatures). The data were subjected to analysis of variance using the General Linear Model procedure (GLM) of SAS ®. For the parameters (number of erythrocytes, rate of hematrocit and values of hemoglobin), there was significant interaction (p <0.05) between treatments in egg and incubation temperatures. Analyzing the interactions for these parameters, it was observed that the application of 0% ascorbic acid in egg minimized the effect of heat stress when compared with treatment without injection. The application of ascorbic acid levels in eggs incubated under heat stress failed to maximize the immunity of newly hatched chicks. It is assumed that the increased liquid in the amniotic fluid, in those embryos injected with water, favored the lower heat conductance for these embryos, thus helping in their development in relation to immunity. Considering that hemoglobin is related to the transport of gases, these data suggest that increasing the concentration of AA solution inoculated may influence the respiratory rates of eggs.
