Aventura espiritual: terapêutica na irmandade dos alcoólicos anônimos

Aborda a compreensão do processo terapêutico no espaço dos Alcoólicos Anônimos (AA) em Belém, Pará, chamado de “recuperação”. Este grupo se apresenta como uma “irmandade”, a qual busca acolher aqueles que considera portadores de doença de natureza física, e espiritual, o alcoolismo, oferecendo-lhes apoio para que alcançar a chamada “sobriedade “. A transição entre uma vida tida como plena de infortúnios, para o que seria uma vida feliz e útil em sua concepção, é possível pela prática de princípios de conduta considerados como espirituais, onde substituem a dependência alcoólica pela dependência ao chamado “Poder Superior”. A “recuperação” no AA diz respeito então ao percurso terapêutico ao qual são submetidos os participantes da Irmandade e nesse sentido é um processo a ser administrado por toda a vida através da participação no grupo. Quando o membro de AA afirma-se recuperado ”ou em recuperação” quer comunicar que não ingere mais bebidas alcoólicas, mas que participa da Irmandade, seguindo os preceitos como recomendado e neste sentido, é que está verdadeiramente sóbrio”. Constata-se que “se recuperar” significa mais do que não ingerir bebidas alcoólicas, pois implica em compartilhar com os demais, as categorias referentes à visão institucional sobre a realidade (saúde, trabalho, família, sexualidade, espiritualidade), assumindo o AA “como um modo de vida”.

Proposição de uma prática experimental significativa em aulas de física

A remarkable characteristic of the physics subject is the abstraction ability needed during the learning process, which means a non-trivial comprehension and understanding. If the students could not link the themes learned in this subject with observable effects, physics would tend to be a group of mathematical formulas to be memorized. In general, it creates a distance between the student and the subject, and also a prejudice vision of the physics, sometimes for the whole life. Beyond this particular characteristics of physics, the education deals with a source of distraction reinforced by the popularization of mobile access such as cellphones and tablets. The traditional role played by the teacher becomes weak to attract student’s attention. It is necessary that the classes could be planned in such way to achieve three goals: attract student attention, link analytical concepts with real effects and, the most important, gives to the student the ability to use the learned concepts as the key to develop new knowledge. In this work, we present a research based in some experiments used in a CBEF (Brazilian magazine about physical education) and develop an activity consistent with the aims to be reached. To prepare of the experimental activity, we based on Piaget and Vygotsky theories. This work aimed to developed a theoretical research to obtain a didactical activity that deals with the current challenges of the society

Asset management of wastewater networks

Asset Management (AM) is a set of procedures operable at the strategic-tacticaloperational level, for the management of the physical asset’s performance, associated risks and costs within its whole life-cycle. AM combines the engineering, managerial and informatics points of view. In addition to internal drivers, AM is driven by the demands of customers (social pull) and regulators (environmental mandates and economic considerations). AM can follow either a top-down or a bottom-up approach. Considering rehabilitation planning at the bottom-up level, the main issue would be to rehabilitate the right pipe at the right time with the right technique. Finding the right pipe may be possible and practicable, but determining the timeliness of the rehabilitation and the choice of the techniques adopted to rehabilitate is a bit abstruse. It is a truism that rehabilitating an asset too early is unwise, just as doing it late may have entailed extra expenses en route, in addition to the cost of the exercise of rehabilitation per se. One is confronted with a typical ‘Hamlet-isque dilemma’ – ‘to repair or not to repair’; or put in another way, ‘to replace or not to replace’. The decision in this case is governed by three factors, not necessarily interrelated – quality of customer service, costs and budget in the life cycle of the asset in question. The goal of replacement planning is to find the juncture in the asset’s life cycle where the cost of replacement is balanced by the rising maintenance costs and the declining level of service. System maintenance aims at improving performance and maintaining the asset in good working condition for as long as possible. Effective planning is used to target maintenance activities to meet these goals and minimize costly exigencies. The main objective of this dissertation is to develop a process-model for asset replacement planning. The aim of the model is to determine the optimal pipe replacement year by comparing, temporally, the annual operating and maintenance costs of the existing asset and the annuity of the investment in a new equivalent pipe, at the best market price. It is proposed that risk cost provide an appropriate framework to decide the balance between investment for replacing or operational expenditures for maintaining an asset. The model describes a practical approach to estimate when an asset should be replaced. A comprehensive list of criteria to be considered is outlined, the main criteria being a visà- vis between maintenance and replacement expenditures. The costs to maintain the assets should be described by a cost function related to the asset type, the risks to the safety of people and property owing to declining condition of asset, and the predicted frequency of failures. The cost functions reflect the condition of the existing asset at the time the decision to maintain or replace is taken: age, level of deterioration, risk of failure. The process model is applied in the wastewater network of Oslo, the capital city of Norway, and uses available real-world information to forecast life-cycle costs of maintenance and rehabilitation strategies and support infrastructure management decisions. The case study provides an insight into the various definitions of ‘asset lifetime’ – service life, economic life and physical life. The results recommend that one common value for lifetime should not be applied to the all the pipelines in the stock for investment planning in the long-term period; rather it would be wiser to define different values for different cohorts of pipelines to reduce the uncertainties associated with generalisations for simplification. It is envisaged that more criteria the municipality is able to include, to estimate maintenance costs for the existing assets, the more precise will the estimation of the expected service life be. The ability to include social costs enables to compute the asset life, not only based on its physical characterisation, but also on the sensitivity of network areas to social impact of failures. The type of economic analysis is very sensitive to model parameters that are difficult to determine accurately. The main value of this approach is the effort to demonstrate that it is possible to include, in decision-making, factors as the cost of the risk associated with a decline in level of performance, the level of this deterioration and the asset’s depreciation rate, without looking at age as the sole criterion for making decisions regarding replacements.

Specification and Verification of Declarative Open Interaction Models - A Logic-based framework

The advent of distributed and heterogeneous systems has laid the foundation for the birth of new architectural paradigms, in which many separated and autonomous entities collaborate and interact to the aim of achieving complex strategic goals, impossible to be accomplished on their own. A non exhaustive list of systems targeted by such paradigms includes Business Process Management, Clinical Guidelines and Careflow Protocols, Service-Oriented and Multi-Agent Systems. It is largely recognized that engineering these systems requires novel modeling techniques. In particular, many authors are claiming that an open, declarative perspective is needed to complement the closed, procedural nature of the state of the art specification languages. For example, the ConDec language has been recently proposed to target the declarative and open specification of Business Processes, overcoming the over-specification and over-constraining issues of classical procedural approaches. On the one hand, the success of such novel modeling languages strongly depends on their usability by non-IT savvy: they must provide an appealing, intuitive graphical front-end. On the other hand, they must be prone to verification, in order to guarantee the trustworthiness and reliability of the developed model, as well as to ensure that the actual executions of the system effectively comply with it. In this dissertation, we claim that Computational Logic is a suitable framework for dealing with the specification, verification, execution, monitoring and analysis of these systems. We propose to adopt an extended version of the ConDec language for specifying interaction models with a declarative, open flavor. We show how all the (extended) ConDec constructs can be automatically translated to the CLIMB Computational Logic-based language, and illustrate how its corresponding reasoning techniques can be successfully exploited to provide support and verification capabilities along the whole life cycle of the targeted systems.

La strategia BIM a supporto del progetto della sicurezza nel cantiere edile: il caso dell'ospedale di primo soccorso a Lampedusa.

Throughout this research, the whole life cycle of a building will be analyzed, with a special focus on the most common issues that affect the construction sector nowadays, such as safety. In fact, the goal is to enhance the management of the entire construction process in order to reduce the risk of accidents. The contemporary trend is that of researching new tools capable of reducing, or even eliminating, the most common mistakes that usually lead to safety risks. That is one of the main reasons why new technologies and tools have been introduced in the field. The one we will focus on is the so-called BIM: Building Information Modeling. With the term BIM we refer to wider and more complex analysis tool than a simple 3D modeling software. Through BIM technologies we are able to generate a multi-dimension 3D model which contains all the information about the project. This innovative approach aims at a better understanding and control of the project by taking into consideration the entire life cycle and resulting in a faster and more sustainable way of management. Furthermore, BIM software allows for the sharing of all the information among the different aspects of the project and among the different participants involved thus improving the cooperation and communication. In addition, BIM software utilizes smart tools that simulate and visualize the process in advance, thus preventing issues that might not have been taking into consideration during the design process. This leads to higher chances of avoiding risks, delays and cost increases. Using a hospital case study, we will apply this approach for the completion of a safety plan, with a special focus onto the construction phase.

The role of dendritic cells (DC) in Friend retrovirus-induced immunosuppression and immunotherapeutic applications of functionalized nanoparticles

Friend murine leukemia Virus (FV) infection of immunocompetent mice is a well- established model to acquire further knowledge about viral immune suppression mechanisms, with the aim to develop therapeutics against retrovirus-induced diseases. Interestingly, BALB/c mice are infected by low doses of FV and die from FV-induced erythroleukemia, while C57/BL6 mice are infected by FV only at high viral dose, and remain persistently infected for their whole life. Due to the central role of dendritic cells (DC) in the induction of anti-viral responses, we asked for their functional role in the genotype-dependent sensitivity towards FV infection. In my PhD study I showed that bone marrow (BM)-derived DC differentiated from FV-infected BM cells obtained from FV-inoculated BALB/c (FV susceptible) and C57BL/6 (FV resistant) mice showed an increased endocytotic activity and lowered expression of MHCII and of costimulatory receptors as compared with non-infected control BMDC. FV-infected BMDC from either mouse strain were partially resistant towards stimulation-induced upregulation of MHCII and costimulators, and accordingly were poor T cell stimulators in vitro and in vivo. In addition, FV-infected BMDC displayed an altered expression profile of proinflammator cytokines and favoured Th2 polarization. Ongoing work is focussed on elucidating the functional role of proteins identified as differentially expressed in FV-infected DC in a genotype-dependent manner, which therefore may contribute to the differential course of FV infection in vivo in BALB/c versus C57BL/6 mice. So far, more than 300 proteins have been identified which are differently regulated in FV-infected vs. uninfected DC from both mouse strains. One of these proteins, S100A9, was strongly upregulated specifically in BMDC derived from FV-infected C57BL/6 BM cells. S100A9-/- mice were more sensitive towards inoculation with FV than corresponding wild type (WT) mice (both C57BL/6 background), which suggests a decisive role of this factor for anti-viral defense. In addition, FV-infected S100A9-/- BMDC showed lower motility than WT DC. The future work is aimed to further elucidate the functional importance of S100A9 for DC functions. To exploit the potential of DC for immunotherapeutic applications, in another project of this PhD study the usability of different types of functionalized nanoparticles

Air bells of water spiders are an extended phenotype modified in response to gas composition

The water spider Argyroneta aquatica (Clerck) is the only spider that spends its whole life under water. Water spiders keep an air bubble around their body for breathing and build under-water air bells, which they use for shelter and raising offspring, digesting and consuming prey, moulting, depositing eggs and sperm, and copulating. It is unclear whether these bells are an important oxygen reservoir for breathing under water, or whether they serve mainly to create water-free space for feeding and reproduction. In this study, we manipulated the composition of the gas inside the bell of female water spiders to test whether they monitor the quality of this gas, and replenish oxygen if required. We exchanged the entire gas in the bell either with pure O(2), pure CO(2), or with ambient air as control, and monitored behavioural responses. The test spiders surfaced and replenished air more often in the CO(2) treatment than in the O(2) treatment, and they increased bell building behaviour. In addition to active oxygen regulation, they monitored and adjusted the bells by adding silk. These results show that water spiders use the air bell as an oxygen reservoir, and that it functions as an external lung, which renders it essential for living under water permanently. A. aquatica is the only animal that collects, transports, and stores air, and monitors its property for breathing, which is an adaptive response of a terrestrial animal to the colonization of an aquatic habitat.

Sublethal neonicotinoid insecticide exposure reduces solitary bee reproductive success

1.Pollinating insects provide crucial and economically important ecosystem services to crops and wild plants, but pollinators, particularly bees, are globally declining as a result of various driving factors, including the prevalent use of pesticides for crop protection. Sublethal pesticide exposure negatively impacts numerous pollinator life-history traits, but its influence on reproductive success remains largely unknown. Such information is pivotal, however, to our understanding of the long-term effects on population dynamics. 2.We investigated the influence of field-realistic trace residues of the routinely used neonicotinoid insecticides thiamethoxam and clothianidin in nectar substitutes on the entire life-time fitness performance of the red mason bee Osmia bicornis. 3.We show that chronic, dietary neonicotinoid exposure has severe detrimental effects on solitary bee reproductive output. Neonicotinoids did not affect adult bee mortality; however, monitoring of fully controlled experimental populations revealed that sublethal exposure resulted in almost 50% reduced total offspring production and a significantly male-biased offspring sex ratio. 4.Our data add to the accumulating evidence indicating that sublethal neonicotinoid effects on non-Apis pollinators are expressed most strongly in a rather complex, fitness-related context. Consequently, to fully mitigate long-term impacts on pollinator population dynamics, present pesticide risk assessments need to be expanded to include whole life-cycle fitness estimates, as demonstrated in the present study using O. bicornis as a model.

El travestismo como metáfora en Sirena Selena vestida de pena de Mayra Santos-Febres

Este artículo explora la figura del travesti en la novela de Mayra Santos- Febres, Sirena Selena vestida de pena (2000) como una metáfora cultural y punto de confluencia de diversos “intereses vestidos". Analizamos esta novela prestando atención al uso literario de la metáfora y a los simbolismos representados a través de la figura del travesti. Es interesante examinar como la literatura puertorriqueña de finales del siglo XX recurre a la figura del travesti por su poder metafórico, y Sirena Selena vestida de pena es un claro ejemplo de dicho poder metafórico de la figura del travesti, una figura que intentamos deconstruir en las siguientes páginas. Hacemos un breve recorrido por la historia del país natal de la escritora, Puerto Rico, ya que esto nos ayuda a identificar un número de metáforas y simbolismos que explotan la realidad del país, y a través de las cuales Santos-Febres llama la atención hacia la movilidad de lo marginal. Hacemos un análisis de las distintas metáforas presentes en el cuerpo del travesti, desde el país colonizado hasta una metáfora del deseo, pasando por el lenguaje, el sistema político, la modernización del país y el Caribe. Por último, analizamos el travestismo como identidad de género en el personaje de Sirena Selena. Sirena es un personaje complejo, un cruce de géneros que acusa la falta de una identidad fija. Investigamos como por medio de la voz y del idioma, toda su vida como cantante y travesti va encaminada a la búsqueda de dicha identidad, tan necesaria para la construcción de un sujeto humano.

Infancia y experiencias de tracción en la obra de R. B. Fuller

Fuller explicitly connects his career with a childhood full of experiences marked by a merger between the biological and the cultural, constituting a major source of imagery, handled over his whole life. Childhood mobile games like the rope, kyte, swing, wheel, or balloon, all characterized by their dynamic condition, serve as narrative vehicles and provide a context to relate childhood, science and architectural design through an universal approach. We pose three elementary cathegories, in order to trace a genealogy of primary technical objects which operate under tension and mobility principles. Rescued experiences, notions and attitudes from Fuller?s childhood memories, refer to the experience of tension which, in clear contrast with traditional structural methods, which perpetuate the Euclidean, the stable, the massive and the compressive, promote multipolar, dynamic en the ephimeral.
