Viver e esperar viver: corpo e identidade na transição de gênero de homens trans

This work seeks to understand how trans men build their identities and live the transsexual experience in the relationships they establish daily onto “man” category. It could be observed that for it they engenders a specific gender transition in the midst of male transsexuality. Despite being under a complex amalgam of relations of exploitation and disciplinary domination, ways of being man are brokered for a living and entry into spaces where they are expelled for not conform the bodies that gender norms require. It is understood that gender transition is a process at the same time of organic and prosthetic body management and the assumption of your own identity. Thus, they build a politic of identity that creatively fixes a person's category as rights holder. The "transition" is therefore to transact from nonexistence to a place of humanity. This dissertation describes how this process takes place in the experiences of the speakers, observing the practices that bring out the male, front of class positions on the labor market, access to health, hormonization and own identity. Thereby, theories that fix them as expressing female masculinities or marginal to the hegemony do not find exactitude in their lives. The research methodologically started performing "multilocated ethnographies" that gave possibilities to in-depth interviews with 15 stakeholders from the Northeast, Midwest, Southeast and South of Brazil. Between 2014 and 2015, from the applying of network technique to the first dialogues in research, it was possible to build a participant observation by the trans men’s everyday life. Wherewith I was capable to behold their own private activities, as well as their public agency amid a trans activism collective in northeast, and the follow-up actions in which they were involved during the XII Encontro Nacional em Universidades de Diversidade Sexual e de Gênero (ENUDSG) held in Mossoró/RN. Therefore, the thesis engages to describe and understand the different ways of constructing trans male gender transitions in access to transsexuality and therefore a way of explaining their own trajectories in terms of people that exist as such, even though in the midst of narratives marked by emotions linked to "not live", to suffering and dehumanization.

As múltiplas dimensões da garantia dos direitos do paciente idoso internado: o caso de uma instituição hospitalar pública no município de Natal/RN

In the context of current capitalist society, marked by the logic that restricts the human person their status as workforce, in order to generate profits, old age is often treated as an underprivileged life stage. This reality becomes more intense considering the sharp aging process that affects brazilian society is accompanied by the country's entry into a globalized world and tensioned by the dictates of capital. Thus, despite the increasing development of policies to strengthen the guarantee of elderly rights, it is necessary to establish effective strategies of these measures to ensure a higher quality of life to these subjects. Therefore, it is necessary to develop studies that problematize the issue of the elderly, which represent a growing portion of the population, and hence have more visible demands, including in health. With the increase in the elderly population in Brazil it is possible to realize the country is going through a demographic transition and epidemiological changes that contribute to change the landscape of health care of the elderly, especially the hospitalization. Thus, this study aimed to analyze the multiple aspects of ensuring the rights of elderly patients admitted to the State Hospital Dr. Ruy Pereira dos Santos (HRPS), located in Natal / RN, whose most patients are elderly. Specifically sought to understand the aging process, its social consequences and the vulnerability to which it is exposed, especially during the disease situation; understand the process of construction of the Brazilian public health and their actions for older people; learn the expressions of citizenship formation in Brazil with regard to policies for older people; and investigate the design of health professionals about the guarantee of the right of hospitalized elderly. Starting from an integrated coordinated theoretical and practical possibilities, a qualitative research and literature character, documentary and field was held. For this, there were four semi-structured interviews with health research locus Hospital professionals - namely, two social workers, a doctor and a nurse - as well as life stories with the hospitalized elderly patients, one in each deck the said Hospital, totaling three. The results pointed to the difficulty of health policy become effective as law and stressed one historical scenario violation of the rights of elderly hospitalized patients, which persists due to the precarious situation and the difficulty of effective implementation of the Unified Health System (SUS ) and other public policies to that end.

Admittance Control for Robotic Loading: Design and Experiments with a 1-Tonne Loader and a 14-Tonne LHD

This paper describes the design, tuning, and extensive field testing of an admittance-based Autonomous Loading Controller (ALC) for robotic excavation. Several iterations of the ALC were tuned and tested in fragmented rock piles—similar to those found in operating mines—by using both a robotic 1-tonne capacity Kubota R520S diesel-hydraulic surface loader and a 14-tonne capacity Atlas Copco ST14 underground load-haul-dump (LHD) machine. On the R520S loader, the ALC increased payload by 18 % with greater consistency, although with more energy expended and longer dig times when compared with digging at maximum actuator velocity. On the ST14 LHD, the ALC took 61 % less time to load 39 % more payload when compared to a single manual operator. The manual operator made 28 dig attempts by using three different digging strategies, and had one failed dig. The tuned ALC made 26 dig attempts at 10 and 11 MN target force levels. All 10 11 MN digs succeeded while 6 of the 16 10 MN digs failed. The results presented in this paper suggest that the admittance-based ALC is more productive and consistent than manual operators, but that care should be taken when detecting entry into the muck pile

Analysis of Poverty Dynamics in Canada (Working Paper 9)

While we know much about poverty (or “low income”) in Canada in a static context, our understanding of the underlying dynamics remains very limited. This is particularly problematic from a policy perspective and the country has been increasingly left out on an international level in this regard. The contribution of this paper is to report the results of an empirical analysis of low income (“poverty”) dynamics in Canada using the recently available “LAD” tax-based database. The paper first describes the general nature of individuals’ poverty profiles (how many are short-term versus longterm, etc.)., the breakdown of the poor population in any given year amongst these different types, and the characterisation of poverty profiles by sex and family type. It then reports the estimation of various econometric models, starting with a set which specifies entry into and exit from poverty in any given year as a function of a variety of personal attributes and situational characteristics, including family status and changes therein, province of residence, inter-provincial mobility, language, area size of residence and calendar year (to capture trend effects). A set of proper hazard models then adds duration effects to these specifications to see how exit and re-entry probabilities shift with the amount of time spent in a poverty spell or after having exited a previous spell. A final set of specifications then investigates “occurrence dependence” effects by including past poverty spells first in an entry model and then with respect to the probability of being poor in a given year. Policy implications are discussed.

Radiopacity and Chemical resistance of Elastomer-Barium sulphate nanocomposites

The Human race of our century is in gluttonous search for novel engineering products which led to a skyrocketed progress in research and fabrication of filled polymers. Recently, a big window has been opened up for speciality polymers especially elastomers with promising properties. Among the many reasons why rubbers are widely used in the process industries, three are considered as important. Firstly, rubbers operate in a variety of environments and possess usable ranges of deformity and durability and can be exploited through suitable and more or less conventional equipment design principles. Secondly, rubber is an eminently suitable construction material for protection against corrosion in the chemical plant and equipment against various corrosive chemicals as, acids and alkalies and if property tailored, can shield ionising radiations as X-rays and gamma rays in medical industry, with minimum maintenance lower down time, negligible corrosion and a preferred choice for aggressive corroding and ionising environment. Thirdly, rubber can readily and hastily, and at a relatively lower cost, be converted into serviceable products, having intricate shapes and dimensions. In a century’s gap, large employment of flexible polymer materials in the different segments of industry has stimulated the development of new materials with special properties, which paved its way to the synthesis of various nanoscale materials. At nano scale, one makes an entry into a world where multidisciplinary sciences meet and utilises the previously unapproached infinitesimal length scale, having dimension which measure upto one billionth of a meter, to create novel properties. The nano fillers augment the elastomers properties in an astonishing fashion due to their multifunctional nature and unprecedented properties have been exhibited by these polymer-nanocomposites just to beat the shortcomings of traditional micro composites. The current research aims to investigate the possibility of using synthesised nano barium sulphate for fabricating elastomer-based nanocomposites and thereby imparting several properties to the rubber. In this thesis, nano materials, their synthesis, structure, properties and applications are studied. The properties of barium sulphate like chemical resistance and radiopacity have been utilized in the present study and is imparted to the elastomers by preparing composites.

Trois essais sur les banques et le pouvoir de marché

Cette thèse examine le rôle du pouvoir de marché dans le marché bancaire. L’emphase est mis sur la prise de risque, les économies d’échelle, l’efficacité économique du marché et la transmission des chocs. Le premier chapitre présente un modèle d’équilibre général dynamique stochastique en économie ouverte comprenant un marché bancaire en concurrence monopolistique. Suivant l’hypothèse de Krugman (1979, 1980) sur la relation entre les économies d’échelle et les exportations, les banques doivent défrayer un coût de transaction pour échanger à l’étranger qui diminue à mesure que le volume de leurs activités locales augmente. Cela incite les banques à réduire leur marge locale afin de profiter davantage du marché extérieur. Le modèle est solutionné et simulé pour divers degrés de concentration dans le marché bancaire. Les résultats obtenus indiquent que deux forces contraires, les économies d’échelle et le pouvoir de marché, s’affrontent lorsque le marché se concentre. La concentration permet aussi aux banques d’accroître leurs activités étrangères, ce qui les rend en contrepartie plus vulnérables aux chocs extérieurs. Le deuxième chapitre élabore un cadre de travail semblable, mais à l’intérieur duquel les banques font face à un risque de crédit. Celui-ci est partiellement assuré par un collatéral fourni par les entrepreneurs et peut être limité à l’aide d’un effort financier. Le modèle est solutionné et simulé pour divers degrés de concentration dans le marché bancaire. Les résultats montrent qu’un plus grand pouvoir de marché réduit la taille du marché financier et de la production à l’état stationnaire, mais incite les banques à prendre moins de risques. De plus, les économies dont le marché bancaire est fortement concentré sont moins sensibles à certains chocs puisque les marges plus élevés donnent initialement de la marge de manoeuvre aux banques en cas de chocs négatifs. Cet effet modérateur est éliminé lorsqu’il est possible pour les banques d’entrer et de sortir librement du marché. Une autre extension avec économies d’échelle montre que sous certaines conditions, un marché moyennement concentré est optimal pour l’économie. Le troisième chapitre utilise un modèle en analyse de portefeuille de type Moyenne-Variance afin de représenter une banque détenant du pouvoir de marché. Le rendement des dépôts et des actifs peut varier selon la quantité échangée, ce qui modifie le choix de portefeuille de la banque. Celle-ci tend à choisir un portefeuille dont la variance est plus faible lorsqu’elle est en mesure d’obtenir un rendement plus élevé sur un actif. Le pouvoir de marché sur les dépôts amène un résultat sembable pour un pouvoir de marché modéré, mais la variance finit par augmenter une fois un certain niveau atteint. Les résultats sont robustes pour différentes fonctions de demandes.

Portrait de la planification de l’implantation du cadre de référence des ressources intermédiaires et de type familial au sein du réseau des établissements de santé et services sociaux du Québec

Suivant l’entrée en vigueur de la Loi sur la représentation des ressources (LRR), le nouveau cadre de référence ressources intermédiaires (RI) et de type familial (RTF) élaboré par le ministère de la Santé et des Services sociaux encadre les changements de pratiques professionnelles. Sachant qu’un tel changement peut entraîner certaines résistances et même un échec, une revue des facteurs favorisant une implantation a été développée, l’objectif étant de dresser un portrait de la situation quant à la planification réalisée dans chacun des établissements. Ainsi, un questionnaire a été envoyé à tous les gestionnaires responsables de l’application du nouveau cadre de référence RI-RTF. Les résultats montrent notamment des lacunes quant à la prévision des incitatifs motivationnels, au développement des objectifs et des indicateurs nécessaires pour suivre l’implantation et favoriser la motivation. Il en ressort aussi que le cadre RI-RTF s’intègre bien à la culture et aux valeurs des établissements.

Novas estratégias para entender o sistema de influxo de antibióticos e a resistência antimicrobiana a nível molecular

As fluoroquinolonas são antibióticos que têm um largo espectro de ação contra bactérias, especialmente Gram-negativas. O seu mecanismo de ação assenta na inibição de enzimas responsáveis pela replicação do DNA. Porém, devido ao seu uso indevido, o surgimento de resistência bacteriana a estes antibióticos tem-se tornado um grave problema de saúde pública. Uma vez que os seus alvos de ação se situam no meio intracelular, a redução da permeabilidade da membrana externa de bactérias Gram-negativas constitui um dos mecanismos de resistência mais conhecidos. Esta redução é associada à baixa expressão ou mutações em porinas necessárias para permitir o seu transporte, mais concretamente, da OmpF. Estudos prévios demonstraram que a coordenação de fluoroquinolonas com iões metálicos divalentes e 1,10-fenantrolina (genericamente designados metaloantibióticos) são potenciais candidatos como alternativa às fluoroquinolonas convencionais. Estes metaloantibióticos exibem um efeito antimicrobiano comparável ou superior à fluoroquinolona na forma livre, mas parecem ter uma via de translocação diferente, independente de porinas. Estas diferenças no mecanismo de captura podem ser fundamentais para contornar a resistência bacteriana. De forma a compreender o papel dos lípidos no mecanismo de entrada dos metaloantibióticos, estudou-se a interação e localização dos metaloantibióticos da Ciprofloxacina (2ª geração), da Levofloxacina (3ª geração) e Moxifloxacina (4ª geração) com um modelo de membranas de Escherichia coli desprovido de porinas. Estes estudos foram realizados através de técnicas de espectroscopia de fluorescência, por medições em modo estacionário e resolvida no tempo. Os coeficientes de partição determinados demonstraram uma interação mais elevada dos metaloantibióticos relativamente às respetivas fluoroquinolonas na forma livre, um facto que está diretamente relacionado com as espécies existentes em solução a pH fisiológico. Os estudos de localização mostraram que estes metaloantibióticos devem estar inseridos na membrana bacteriana, confirmando a sua entrada independente de porinas. Este mecanismo de entrada, pela via hidrofóbica, é potenciado por interações eletrostáticas entre as espécies catiónicas de metaloantibiótico que existem a pH 7,4 e os grupos carregados negativamente dos fosfolípidos da membrana. Desta forma, os resultados obtidos neste estudo sugerem que a via de entrada dos metaloantibióticos e das respetivas fluoroquinolonas deve ser diferente. Os metaloantibióticos são candidatos adequados para a realização de mais testes laboratoriais e uma alternativa promissora para substituir as fluoroquinolonas convencionais, uma vez que parecem ultrapassar um dos principais mecanismos de resistência bacteriana a esta classe de antibióticos.

Market work and household production in Brazil

This thesis is composed of three papers in which the research questions are related to the double burden that accrues to Brazilian women. The first and second papers address this issue by looking at expenditure decisions about home production. The first paper examines whether the expenditure decisions about production goods, such as white appliances, relative to entertainment goods, such as TVs, are the outcome of a bargaining process between husbands and wives. The second paper looks at the demand for maid services and for production durable goods, examining the extent to which other household members substitute for maid services and durable goods in home production. The third paper addresses the effects of Brazilian women's double burden on their labor market participation by examining whether the occupational choice of Brazilian women is affected by their gender roles and whether entry into other occupations that are not identified as female occupations has become easier since the introduction of anti-discrimination laws in the labor market. The first paper combines two Brazilian data sets: a Brazilian household expenditure survey, Pesquisa de Orçamento Familiares (POF), and a Brazilian household survey, Pesquisa Nacional Por Amostra de Domicílios (PNAD). The results of the first paper indicate that the decision about durable goods ownership is the outcome of a bargaining process between husband and wife. The test on the coefficients of the marriage market variable and the indicators of households in which only the wife and households in which only the husband makes expenditure decisions corroborate the expectations about wives' preferences for production goods. The same data sets as the first paper are used in the second paper. The finding of the second paper indicates that if the marriage market is favorable to women, that is if the ratio of women to men goes from 1.07 to 0.96, the increment in the household probability of owning at least one maid's substitute durable goods is equivalent to 24% the impact of moving a household up one income quintile. Moreover, the results indicate that daughters' time substitutes for wives' time and maid services in home production. Parents may want daughters trained in home production to be able to perform their future role as wives. However, this training comes at a cost to daughters' investment in formal education, narrowing their future career options. The data used in the third paper come from a Brazilian household survey, Pesquisa Nacional Por Amostra de Domicílios (PNAD). Gender roles are responsible for women to choose female-dominated occupations, married women are 1.14 times more likely to work in female-dominated occupations and having a child six years and older increases on average by 12% the probability that women work in female-dominated occupations instead of genderintegrated occupations in 2001. However, it becomes easier for all types of women to enter into male-dominated and gender-integrated occupations in 2001 compared to 1981.

Interação da cianotoxina microcistina e o nanomaterial de carbono fulereno (C60) em brânquias do peixe Cyprinus carpio (Teleostei: Cyprinidae) sob incidência de radiação UVA

A produção mundial de nanomateriais tem aumentado nos últimos anos, em função de suas variadas aplicações tecnológicas e, como consequência do seu crescente uso e demanda, poderão existir riscos ambientais sendo a água o ambiente onde muitas destas substâncias podem exercer efeitos deletérios. Um dos nanomaterias de carbono mais utilizados é o fulereno, um composto orgânico lipofílico que pode se comportar como carreador de moléculas tóxicas, potencializando a entrada de contaminantes ambientais em órgãos específicos, fenômeno conhecido como “cavalo de Troia”. As microcistinas (MC) são cianotoxinas produzidas por cianobactérias durante episódios de floração, afetando aos organismos aquáticos e ao ser humano. Diversos estudos demonstram que organismos expostos tanto às MCs quanto ao fulereno podem causar produção excessiva de espécies ativas de oxigênio e alterar os níveis de antioxidantes. Além disso, outro fator que pode vir a intensificar o potencial tóxico de ambos é a incidência de radiação UVA. Sendo assim, procurou-se avaliar os efeitos em parâmetros de estresse oxidativo da co-exposição ex vivo da cianotoxina microcistina-LR (MC-LR) e o nanomaterial de carbono fulereno em brânquias do peixe Cyprinus carpio sob incidência de radiação UVA. Os resultados mostraram que: (a) houve uma perda da capacidade antioxidante no tratamento com MC-LR (baixa concentração) quando coexposta com fulereno no UVA em relação com o tratamento realizado sem co-exposição com fulereno; (b) o fulereno no UV diminuiu a atividade da enzima glutationa-Stransferase (GST) quando comparado com o controle no UV; (c) a MC-LR (alta concentração) co-exposta com fulereno foi capaz de diminuir as concentrações do antioxidante glutationa (GSH) quando comparado com o mesmo tratamento tanto no UVA quanto no escuro sem a co-exposição ao fulereno; (d) o tratamento MC-LR (baixa concentração) com UVA aumentou o dano oxidativo lipídico quando comparado com o controle UVA; (e) o fulereno não causou uma maior bioacumulação da microcistina no tecido. Sendo assim, pode-se concluir que o fulereno não apresentou o potencial de carregador de moléculas nessas concentrações de microcistina, porém, a co-exposição dos compostos diminuem tanto capacidade antioxidante total, como a concentração da GSH, podendo gerar problemas a longo prazo na detoxificação da toxina.

Life without complex I: proteome analyses of an Arabidopsis mutant lacking the mitochondrial NADH dehydrogenase complex

The mitochondrial NADH dehydrogenase complex (complex I) is of particular importance for the respiratory chain in mitochondria. It is the major electron entry site for the mitochondrial electron transport chain (mETC) and therefore of great significance for mitochondrial ATP generation. We recently described an Arabidopsis thaliana double-mutant lacking the genes encoding the carbonic anhydrases CA1 and CA2, which both form part of a plant-specific 'carbonic anhydrase domain' of mitochondrial complex I. The mutant lacks complex I completely. Here we report extended analyses for systematically characterizing the proteome of the ca1ca2 mutant. Using various proteomic tools, we show that lack of complex I causes reorganization of the cellular respiration system. Reduced electron entry into the respiratory chain at the first segment of the mETC leads to induction of complexes II and IV as well as alternative oxidase. Increased electron entry at later segments of the mETC requires an increase in oxidation of organic substrates. This is reflected by higher abundance of proteins involved in glycolysis, the tricarboxylic acid cycle and branched-chain amino acid catabolism. Proteins involved in the light reaction of photosynthesis, the Calvin cycle, tetrapyrrole biosynthesis, and photorespiration are clearly reduced, contributing to the significant delay in growth and development of the double-mutant. Finally, enzymes involved in defense against reactive oxygen species and stress symptoms are much induced. These together with previously reported insights into the function of plant complex I, which were obtained by analysing other complex I mutants, are integrated in order to comprehensively describe 'life without complex I'.

Feasibility study to inform the design of a UK multi-centre randomised controlled trial of prophylactic antibiotics for the prevention of recurrent cellulitis of the leg

Background: This paper describes the results of a feasibility study for a randomised controlled trial (RCT). Methods: Twenty-nine members of the UK Dermatology Clinical Trials Network (UK DCTN) expressed an interest in recruiting for this study. Of these, 17 obtained full ethics and Research & Development (R&D) approval, and 15 successfully recruited patients into the study. A total of 70 participants with a diagnosis of cellulitis of the leg were enrolled over a 5-month period. These participants were largely recruited from medical admissions wards, although some were identified from dermatology, orthopaedic, geriatric and general surgery wards. Data were collected on patient demographics, clinical features and willingness to take part in a future RCT. Results: Despite being a relatively common condition, cellulitis patients were difficult to locate through our network of UK DCTN clinicians. This was largely because patients were rarely seen by dermatologists, and admissions were not co-ordinated centrally. In addition, the impact of the proposed exclusion criteria was high; only 26 (37%) of those enrolled in the study fulfilled all of the inclusion criteria for the subsequent RCT, and were willing to be randomised to treatment. Of the 70 participants identified during the study as having cellulitis of the leg (as confirmed by a dermatologist), only 59 (84%) had all 3 of the defining features of: i) erythema, ii) oedema, and iii) warmth with acute pain/tenderness upon examination. Twenty-two (32%) patients experienced a previous episode of cellulitis within the last 3 years. The median time to recurrence (estimated as the time since the most recent previous attack) was 205 days (95% CI 102 to 308). Service users were generally supportive of the trial, although several expressed concerns about taking antibiotics for lengthy periods, and felt that multiple morbidity/old age would limit entry into a 3-year study. Conclusion: This pilot study has been crucial in highlighting some key issues for the conduct of a future RCT. As a result of these findings, changes have been made to i) the planned recruitment strategy, ii) the proposed inclusion criteria and ii) the definition of cellulitis for use in the future trial.

Glosa do postanowienia Naczelnego Sądu Administracyjnego z dnia 13 stycznia 2016 r., sygn. akt II GZ 927/15

W glosowanym orzeczeniu Naczelny Sąd Administracyjny stwierdził, że od postanowień wojewódzkich sądów administracyjnych odrzucających skargi z przyczyn formalnych w sprawach wszczętych przed dniem wejścia w życie nowelizacji Prawa o postępowaniu przed sądami administracyjnymi (co miało miejsce 15 sierpnia 2015 r.) przysługuje zażalenie, a nie skarga kasacyjna. Przedmiotowe zagadnienie prawne sprowadza się do właściwej wykładni źle sformułowanych przepisów intertemporalnych. W glosie zaprezentowano istotę środków odwoławczych w postępowaniu sądowoadministracyjnym i scharakteryzowano krótko ostatnią nowelizację Prawa o postępowaniu przed sądami administracyjnymi. Autor prezentuje stanowisko krytyczne w stosunku do tezy postanowienia Naczelnego Sądu Administracyjnego, wskazując, że sąd powinien rozstrzygnąć sprawę co do jej istoty. Pogląd ten został poparty odpowiednią argumentacją z uwzględnieniem konkurencyjnego orzecznictwa Naczelnego Sądu Administracyjnego.
