AS RELAÇÕES INVERTIDAS NO HADES: HUMOR IRÔNICO E CRÍTICA SOCIAL NA NARRATIVA DO HOMEM RICO E DO POBRE LÁZARO

O trabalho aborda a micronarrativa do Homem rico e do pobre Lázaro de Lc. 16. 19-31. As relações entre os dois personagens da narrativa se mostram invertidas, sugerindo um tom irônico por parte do narrador lucano. A inversão os coloca no mesmo lugar, o Hades, mas em posições diferentes, gerando um conflito na narrativa. Buscou-se observar o motivo da inversão, seu papel na cena e seu impacto na trama da narrativa e em seus leitores. Examinou-se na sequência narrativa da parábola a relação entre seu enredo unificante e seu enredo episódico buscando o motivo dela dentro dessa sequência, o que demonstrou ser uma narrativa direcionada aos fariseus, onde sugerimos ter um tom irônico em uma crítica social. Buscou-se retratar o imaginário desse lugar de inversão, trazendo algumas imagens do imaginário judaico e greco-romano a partir de algumas fontes literárias, principalmente a obra Diálogo dos Mortos, de Luciano de Samósata do II séc. Demonstrou-se haver uma intertextualidade, onde ecos do relato lucano são vistos na obra de Luciano. Para tal elaboração, os passos da narratologia evidenciaram o que se pretendeu analisar.

Resistance Performances: (Re)constructing Spaces of Resistance and Contention in the 2010-2011 University of Puerto Rico Student Movement

On the night of April 20, 2010, a group of students from the University of Puerto Rico (UPR), Río Piedras campus, met to organize an indefinite strike that quickly broadened into a defense of accessible public higher education of excellence as a fundamental right and not a privilege. Although the history of student activism in the UPR can be traced back to the early 1900s, the 2010-2011 strike will be remembered for the student activists’ use of new media technologies as resources that rapidly prompted and aided the numerous protests. This activist research entailed a critical ethnography and a critical discourse analysis (CDA) of traditional and alternative media coverage and treatment during the 2010 -2011 UPR student strike. I examined the use of the 2010-2011 UPR student activists’ resistance performances in constructing local, corporeal, and virtual spaces of resistance and contention during their movement. In particular, I analyzed the different tactics and strategies of resistance or repertoire of collective actions that student activists used (e.g. new media technologies) to frame their collective identities via alternative news media’s (re)presentation of the strike, while juxtaposing the university administration’s counter-resistance performances in counter-framing the student activists’ collective identity via traditional news media representations of the strike. I illustrated how both traditional and alternative media (re)presentations of student activism developed, maintained, and/or modified students activists’ collective identities. As such, the UPR student activism’s success should not be measured by the sum of demands granted, but by the sense of community achieved and the establishment of networks that continue to create resistance and change. These networks add to the debate surrounding Internet activism and its impact on student activism. Ultimately, the results of this study highlight the important role student movements have had in challenging different types of government policies and raising awareness of the importance of an accessible public higher education of excellence.

Leaf Functional Traits and Forest Structure of Tropical Dry Forest Species Along a Rainfall Gradient in Florida and Puerto Rico

This study examined how different rainfall regimes affect a set of leaf functional traits related to plant stress and forest structure in tropical dry forest (TDF) species on limestone substrate. One hundred fifty eight individuals of four tree species were sampled in six ecological sites in south Florida and Puerto Rico, ranging in mean annual rainfall from 858 to 1933 mm yr-1. Leaf nitrogen content, specific leaf area (SLA), and N:P ratio of evergreen species, but not deciduous species, responded positively to increasing rainfall. Phosphorus content was unaffected in both groups. Canopy height and basal area reached maxima of 10.3 m and 31.4 m2 ha-1, respectively, at 1168 mm annual rainfall. Leaf traits reflected soil properties only to a small extent. This led us to the conclusion that water is a major limiting factor in TDF and some species that comprise TDF ecosystems are limited by nitrogen in limestone sites with less than ~1012 mm rainfall, but organismal, biological and/or abiotic forces other than rainfall control forest structure in moister sites.

A democracia participativa na jurisdição constitucional brasileira: o amicus curiae enquanto mediador democrático no controle concentrado de constitucionalidade no Supremo Tribunal Federal

This master thesis aims to research the tension established between the judicial review and democratic theory which was always present in the constitutional doctrine of separation of powers. In this regard, the expansion of the Brazilian constitutional jurisdiction checked after the occurrence of the Federal Constitution of 1988 and the inertia of the Legislature in disciplinary relevant legal aspects of Brazilian society contributed to a hyperactivity of the Supreme Court. However, in a complex society of context, as is the Brazilian society, there are contained demands and political controversies that hardly would be well represented or resolved through the action of the Court of ministers at the expense of other government bodies. Among the supremacy of Parliament and the legitimacy deficit of these magistrates, is the constitutional text and the social fabric that makes this legal status of the political. Participatory democracy established by the guidelines of the Federal Constitution requires this perspective when the Supreme Court acting in place of concentrated constitutionality control. In a plural society, there is no reason to get rid of state decision moments popular participation. Lack the Supreme Court, this time, the democratizing perception that the institute brings to the interior of the Court, as state determination of space in which to come together and meet the aspirations of society and state claims. The dissertation investigates thus the possibility of amicus curiae Institute serve as a mediator of the democratic debate, to assist the Supreme Court in the preparation of the decision is, historically, that which is of greater legitimacy, from the perspective of a theory participatory democracy. Analyzes, likewise, the unfolding of abstract judicial review in the context of Brazilian law. Proposes, incidentally, a rereading of the separation of powers, with the call for the Judiciary be careful not to become the protagonist of national political decisions. It maintains, finally, that procedural opening the interpreters of the constitution, through the amicus curiae Institute, shows up as able to decrease the legitimacy deficit in the performance of the Brazilian Supreme Court.

Influência da pressão e da vazão de concentrado sobre o desempenho de ultrafiltração no pós-tratamento de esgotos

Despite the numerous advantages resulting from the use of membrane filters technology, intrinsic limitations fouling process become relevant to its applicability. The control of operating conditions is an important tool to mitigate fouling and achieve good levels of efficiency. In this sense, the objective of this study was to investigate the effect of transmembrane pressure and concentrate flow in the performance of ultrafiltration, applied to the post-treatment of domestic sewage. The process was evaluated and optimized by varying the pressure (0.5 and 1.5 bar) and the concentrate flow (300 and 600 L/h), using a 22 factorial design, in order to investigate the effects on the permeate flow and quality of effluents generated at each operating condition. We evaluated the following quality indicators for permeate: pH, electrical conductivity, total suspended solids, turbidity, calcium and Chemical Oxygen Demand (COD). In all tests, we observed marked reduction in the permeate flux at the early stages, followed by a slow decline that lasted until it reaches a relatively constant level, around 120 minutes of filtration. The increased pressure resulted in a higher initial permeate flux, but the decrease of the flow with time is greater for tests at higher pressure, indicating a more pronounced fouling process. On the other hand, increasing the concentrate flow resulted in a slower decline in permeate flux with the filtration time. Regarding the quality of permeate, the transmembrane pressure of 0,5 bar was the one that allowed better results, and was statistically confirmed through the two-way ANOVA test with repeated measures, significant effect of pressure on the turbidity of the permeate. The concentrate flow, in turn, showed no significant influence on any of the quality parameters. Thus, we conclude that, from an economic and environmental point of view, it is more interesting to operate ultrafiltration membrane system with a lower concentrate flow associated with a low transmembrane pressure, since under these conditions will produce less waste, and the permeate will present lower concentrations of the analyzed constituent, especially lower turbidity.

Efeito do exercício físico na estabilidade de membrana de eritrócitos

CHAPTER II - This study evaluated the effects of two different types of acute aerobic exercise on the osmotic stability of human erythrocyte membrane and on different hematological and biochemical variables that are associated with this membrane property. The study population consisted of 20 healthy and active men. Participants performed single sessions of two types of exercise. The first session consisted of 60 min of moderate-intensity continuous exercise (MICE). The second session, executed a week later, consisted of high-intensity interval exercise (HIIE) until exhaustion. The osmotic stability of the erythrocyte membrane was represented by the inverse of the salt concentration (1/H50) at the midpoint of the sigmoidal curve of dependence between the absorbance of hemoglobin and the NaCl concentration. The values of 1/H50 changed from 2.29 ± 0.1 to 2.33 ± 0.09 after MICE and from 2.30 ± 0.08 to 2.23 ± 0.12 after HIIE. In MICE has occurred an increase in the mean corpuscular volume, probably due to in vivo lysis of older erythrocytes, with preservation of cells that were larger and more resistant to in vitro lysis. The study showed that a single bout of acute exercise affected the erythrocyte osmotic stability, which increased after MICE and decreased after HIIE.

El papel de los carteles de la División de Gráfica y Cine de Parques y Recreo Público en la redefinición colonial del Puerto Rico de mediados del siglo XX

El cartel serigráfico del proyecto de carteles del Taller de Cinema y Gráfica de Parques y Recreo Público se utilizó como medio para educar e insertar a las grandes masas dentro de las reformas coloniales ocurridas como consecuencia de la entrada de Estados Unidos a la Segunda Guerra Mundial y readiestrar a la población puertorriqueña, entonces compuesta por campesinos, para servir como mano de obra barata y dócil al proyecto colonial y a los beneficiarios del proyecto de industrialización de la posguerra. Se ha dicho en innumerables ocasiones que el camino al infierno está repleto de buenas intenciones; este es el relato de un viaje de ida. Los carteles de la División de Cinema y Gráfica de Parques y Recreo Público mantienen desde el origen varios elementos inquietantes de lo que se podría denominar como la política de reconstrucción de una colonia, de un territorio objeto de la sujeción/subyugación por parte de otro país, y presentarlo como un objetivo plausible, de consideración y cumplimiento con los derechos humanos fundamentales...

Life Experiences of Youth Who Were Born with HIV Infection in Puerto Rico: The Voices of Young Survivors

The effectiveness of antiretroviral therapy (ART) transformed the pediatric HIV epidemic. The disease changed significantly over the course of three decades: while early in the epidemic it was almost always fatal, it has become a chronic condition. This study examined how perinatally-infected youth experience the impact of HIV in their lives. A qualitative study using interpretative phenomenological analysis (IPA) was conducted. Twenty in-depth interviews were carried out among 12 women and 8 men aged 18 to 30 years in Puerto Rico. These were conducted in Spanish, audio-recorded, transcribed and translated into English. While narrating their experiences, participants were interpreting what the situation meant to them and how they make sense of it. Three topics emerged: (1) perception and response to treatment and illness, particularly their lived experiences with ART; (2) disclosure experiences; and (3) family matters. Most participants challenged their therapy, in most cases to force their caregivers to disclose their status. Problems with adherence were attributed to busy schedules or forgetfulness. Participants experienced the disfiguring adverse effects of ART, which they endured for years without being informed that ART was the cause of these. Participants’ experiences with disclosure demonstrated the importance of validating them as individuals capable of managing their health. The paternalistic approach of withholding their diagnosis to spare them suffering resulted in increased anxiety. Participants acknowledged the difficulties of revealing their HIV status to their partners. They referred to family and friends as essential in coping with HIV. However, some encountered discrimination and stigma within their families. Participants who had suffered the loss of their parents found other parental figures such as adoptive parents or other family members. Most participants expressed a desire to have children. Perinatally HIV-infected youth will require health services for the rest of their lives. The adult health care into which they transition should consider their needs and journey. Services should consider including family members. This study underscores the need for improved access to mental health services. It is also essential to transcend medical treatment and develop a broader perspective of health care. Health care services should include reproductive decision-making counselling services.
