A análise do discurso diante de estranhos espelhos: visualidade e (inter)discursividade na pintura

This paper aims to understand the discursive dimension of some paintings through Michel Foucault'sdiscourse analysis approach. The image of the mirror in several canonical paintings was selected, intending to observe its discursive operation as an element of the visual artistic utterance. Basically, this text has three parts: firstly, it determines the place occupied by the aesthetic discourse in Michel Pêcheux's and Michel Foucault's works; secondly, it focuses on the analysis of three European paintings, namely The Maids of Honour by Velásquez, A Bar at the Folies-Bergère by Manet, and Dangerous Liaisons by Magritte; thirdly, it discusses the intersection between visuality and interdiscursivity based on a) the contributions of M. Foucault's works on aesthetic discourse and b) the image of the mirror found in those paintings.

Light energy management in peach: utilization, photoprotection , photodamage and recovery. Maximizing light absorption in orchard is not always the best solution

The relation between the intercepted light and orchard productivity was considered linear, although this dependence seems to be more subordinate to planting system rather than light intensity. At whole plant level not always the increase of irradiance determines productivity improvement. One of the reasons can be the plant intrinsic un-efficiency in using energy. Generally in full light only the 5 – 10% of the total incoming energy is allocated to net photosynthesis. Therefore preserving or improving this efficiency becomes pivotal for scientist and fruit growers. Even tough a conspicuous energy amount is reflected or transmitted, plants can not avoid to absorb photons in excess. The chlorophyll over-excitation promotes the reactive species production increasing the photoinhibition risks. The dangerous consequences of photoinhibition forced plants to evolve a complex and multilevel machine able to dissipate the energy excess quenching heat (Non Photochemical Quenching), moving electrons (water-water cycle , cyclic transport around PSI, glutathione-ascorbate cycle and photorespiration) and scavenging the generated reactive species. The price plants must pay for this equipment is the use of CO2 and reducing power with a consequent decrease of the photosynthetic efficiency, both because some photons are not used for carboxylation and an effective CO2 and reducing power loss occurs. Net photosynthesis increases with light until the saturation point, additional PPFD doesn’t improve carboxylation but it rises the efficiency of the alternative pathways in energy dissipation but also ROS production and photoinhibition risks. The wide photo-protective apparatus, although is not able to cope with the excessive incoming energy, therefore photodamage occurs. Each event increasing the photon pressure and/or decreasing the efficiency of the described photo-protective mechanisms (i.e. thermal stress, water and nutritional deficiency) can emphasize the photoinhibition. Likely in nature a small amount of not damaged photosystems is found because of the effective, efficient and energy consuming recovery system. Since the damaged PSII is quickly repaired with energy expense, it would be interesting to investigate how much PSII recovery costs to plant productivity. This PhD. dissertation purposes to improve the knowledge about the several strategies accomplished for managing the incoming energy and the light excess implication on photo-damage in peach. The thesis is organized in three scientific units. In the first section a new rapid, non-intrusive, whole tissue and universal technique for functional PSII determination was implemented and validated on different kinds of plants as C3 and C4 species, woody and herbaceous plants, wild type and Chlorophyll b-less mutant and monocot and dicot plants. In the second unit, using a “singular” experimental orchard named “Asymmetric orchard”, the relation between light environment and photosynthetic performance, water use and photoinhibition was investigated in peach at whole plant level, furthermore the effect of photon pressure variation on energy management was considered on single leaf. In the third section the quenching analysis method suggested by Kornyeyev and Hendrickson (2007) was validate on peach. Afterwards it was applied in the field where the influence of moderate light and water reduction on peach photosynthetic performances, water requirements, energy management and photoinhibition was studied. Using solar energy as fuel for life plant is intrinsically suicidal since the high constant photodamage risk. This dissertation would try to highlight the complex relation existing between plant, in particular peach, and light analysing the principal strategies plants developed to manage the incoming light for deriving the maximal benefits as possible minimizing the risks. In the first instance the new method proposed for functional PSII determination based on P700 redox kinetics seems to be a valid, non intrusive, universal and field-applicable technique, even because it is able to measure in deep the whole leaf tissue rather than the first leaf layers as fluorescence. Fluorescence Fv/Fm parameter gives a good estimate of functional PSII but only when data obtained by ad-axial and ab-axial leaf surface are averaged. In addition to this method the energy quenching analysis proposed by Kornyeyev and Hendrickson (2007), combined with the photosynthesis model proposed by von Caemmerer (2000) is a forceful tool to analyse and study, even in the field, the relation between plant and environmental factors such as water, temperature but first of all light. “Asymmetric” training system is a good way to study light energy, photosynthetic performance and water use relations in the field. At whole plant level net carboxylation increases with PPFD reaching a saturating point. Light excess rather than improve photosynthesis may emphasize water and thermal stress leading to stomatal limitation. Furthermore too much light does not promote net carboxylation improvement but PSII damage, in fact in the most light exposed plants about 50-60% of the total PSII is inactivated. At single leaf level, net carboxylation increases till saturation point (1000 – 1200 μmolm-2s-1) and light excess is dissipated by non photochemical quenching and non net carboxylative transports. The latter follows a quite similar pattern of Pn/PPFD curve reaching the saturation point at almost the same photon flux density. At middle-low irradiance NPQ seems to be lumen pH limited because the incoming photon pressure is not enough to generate the optimum lumen pH for violaxanthin de-epoxidase (VDE) full activation. Peach leaves try to cope with the light excess increasing the non net carboxylative transports. While PPFD rises the xanthophyll cycle is more and more activated and the rate of non net carboxylative transports is reduced. Some of these alternative transports, such as the water-water cycle, the cyclic transport around the PSI and the glutathione-ascorbate cycle are able to generate additional H+ in lumen in order to support the VDE activation when light can be limiting. Moreover the alternative transports seems to be involved as an important dissipative way when high temperature and sub-optimal conductance emphasize the photoinhibition risks. In peach, a moderate water and light reduction does not determine net carboxylation decrease but, diminishing the incoming light and the environmental evapo-transpiration request, stomatal conductance decreases, improving water use efficiency. Therefore lowering light intensity till not limiting levels, water could be saved not compromising net photosynthesis. The quenching analysis is able to partition absorbed energy in the several utilization, photoprotection and photo-oxidation pathways. When recovery is permitted only few PSII remained un-repaired, although more net PSII damage is recorded in plants placed in full light. Even in this experiment, in over saturating light the main dissipation pathway is the non photochemical quenching; at middle-low irradiance it seems to be pH limited and other transports, such as photorespiration and alternative transports, are used to support photoprotection and to contribute for creating the optimal trans-thylakoidal ΔpH for violaxanthin de-epoxidase. These alternative pathways become the main quenching mechanisms at very low light environment. Another aspect pointed out by this study is the role of NPQ as dissipative pathway when conductance becomes severely limiting. The evidence that in nature a small amount of damaged PSII is seen indicates the presence of an effective and efficient recovery mechanism that masks the real photodamage occurring during the day. At single leaf level, when repair is not allowed leaves in full light are two fold more photoinhibited than the shaded ones. Therefore light in excess of the photosynthetic optima does not promote net carboxylation but increases water loss and PSII damage. The more is photoinhibition the more must be the photosystems to be repaired and consequently the energy and dry matter to allocate in this essential activity. Since above the saturation point net photosynthesis is constant while photoinhibition increases it would be interesting to investigate how photodamage costs in terms of tree productivity. An other aspect of pivotal importance to be further widened is the combined influence of light and other environmental parameters, like water status, temperature and nutrition on peach light, water and phtosyntate management.

On dangers to rational exploitation and development of the resources of the great lakes of Africa

The major dangers facing the resources of the Great Lakes of Africa include over exploitation, falling species diversity, accumulating pollution, and a probable decline in fishery productivity. These dangers may be viewed as accentuated by: i) Inadequate scientific knowledge on the exploited resources ii) Reluctance to apply even the limited scientific information available, by fishery administrators iii) Constant increase in the demand for fish and other aquatic resources. iv) Lack of commitment to active collaboration and co-operation by riparian states regarding development and management of the shared resources. This paper discusses the above factors in relation to the dangerous trends facing the resources of the Great Lakes of Africa. The discussion is intended to contribute to the promotion of rational and sustainable utilisation of the aquatic resources of these lakes.

Rural and remote road safety study : final report

• Introduction: Concern and action for rural road safety is relatively new in Australia in comparison to the field of traffic safety as a whole. In 2003, a program of research was begun by the Centre for Accident Research and Road Safety - Queensland (CARRS-Q) and the Rural Health Research Unit (RHRU) at James Cook University to investigate factors contributing to serious rural road crashes in the North Queensland region. This project was funded by the Premier’s Department, Main Roads Department, Queensland Transport, QFleet, Queensland Rail, Queensland Ambulance Service, Department of Natural Resources and Queensland Police Service. Additional funding was provided by NRMA Insurance for a PhD scholarship. In-kind support was provided through the four hospitals used for data collection, namely Cairns Base Hospital, The Townsville Hospital, Mount Isa Hospital and Atherton Hospital.----- The primary aim of the project was to: Identify human factors related to the occurrence of serious traffic incidents in rural and remote areas of Australia, and to the trauma suffered by persons as a result of these incidents, using a sample drawn from a rural and remote area in North Queensland.----- The data and analyses presented in this report are the core findings from two broad studies: a general examination of fatalities and casualties from rural and remote crashes for the period 1 March 2004 until 30 June 2007, and a further linked case-comparison study of hospitalised patients compared with a sample of non-crash-involved drivers.----- • Method: The study was undertaken in rural North Queensland, as defined by the Australian Bureau of Statistics (ABS) statistical divisions of North Queensland, Far North Queensland and North-West Queensland. Urban areas surrounding Townsville, Thuringowa and Cairns were not included. The study methodology was centred on serious crashes, as defined by a resulting hospitalisation for 24 hours or more and/or a fatality. Crashes meeting this criteria within the North Queensland region between 1 March 2004 and 30 June 2007 were identified through hospital records and interviewed where possible. Additional data was sourced from coroner’s reports, the Queensland Transport road crash database, the Queensland Ambulance Service and the study hospitals in the region.----- This report is divided into chapters corresponding to analyses conducted on the collected crash and casualty data.----- Chapter 3 presents an overview of all crashes and casualties identified during the study period. Details are presented in regard to the demographics and road user types of casualties; the locations, times, types, and circumstances of crashes; along with the contributing circumstances of crashes.----- Chapter 4 presents the results of summary statistics for all casualties for which an interview was able to be conducted. Statistics are presented separately for drivers and riders, passengers, pedestrians and cyclists. Details are also presented separately for drivers and riders crashing in off-road and on-road settings. Results from questionnaire data are presented in relation to demographics; the experience of the crash in narrative form; vehicle characteristics and maintenance; trip characteristics (e.g. purpose and length of journey; periods of fatigue and monotony; distractions from driving task); driving history; alcohol and drug use; medical history; driving attitudes, intentions and behaviour; attitudes to enforcement; and experience of road safety advertising.----- Chapter 5 compares the above-listed questionnaire results between on-road crash-involved casualties and interviews conducted in the region with non-crash-involved persons. Direct comparisons as well as age and sex adjusted comparisons are presented.----- Chapter 6 presents information on those casualties who were admitted to one of the study hospitals during the study period. Brief information is given regarding the demographic characteristics of these casualties. Emergency services’ data is used to highlight the characteristics of patient retrieval and transport to and between hospitals. The major injuries resulting from the crashes are presented for each region of the body and analysed by vehicle type, occupant type, seatbelt status, helmet status, alcohol involvement and nature of crash. Estimates are provided of the costs associated with in-hospital treatment and retrieval.----- Chapter 7 describes the characteristics of the fatal casualties and the nature and circumstances of the crashes. Demographics, road user types, licence status, crash type and contributing factors for crashes are presented. Coronial data is provided in regard to contributing circumstances (including alcohol, drugs and medical conditions), cause of death, resulting injuries, and restraint and helmet use.----- Chapter 8 presents the results of a comparison between casualties’ crash descriptions and police-attributed crash circumstances. The relative frequency of contributing circumstances are compared both broadly within the categories of behavioural, environmental, vehicle related, medical and other groupings and specifically for circumstances within these groups.----- Chapter 9 reports on the associated research projects which have been undertaken on specific topics related to rural road safety.----- Finally, Chapter 10 reports on the conclusions and recommendations made from the program of research.---- • Major Recommendations : From the findings of these analyses, a number of major recommendations were made: + Male drivers and riders - Male drivers and riders should continue to be the focus of interventions, given their very high representation among rural and remote road crash fatalities and serious injuries.----- - The group of males aged between 30 and 50 years comprised the largest number of casualties and must also be targeted for change if there is to be a meaningful improvement in rural and remote road safety.----- + Motorcyclists - Single vehicle motorcycle crashes constitute over 80% of serious, on-road rural motorcycle crashes and need particular attention in development of policy and infrastructure.----- - The motorcycle safety consultation process currently being undertaken by Queensland Transport (via the "Motorbike Safety in Queensland - Consultation Paper") is strongly endorsed. As part of this process, particular attention needs to be given to initiatives designed to reduce rural and single vehicle motorcycle crashes.----- - The safety of off-road riders is a serious problem that falls outside the direct responsibility of either Transport or Health departments. Responsibility for this issue needs to be attributed to develop appropriate policy, regulations and countermeasures.----- + Road safety for Indigenous people - Continued resourcing and expansion of The Queensland Aboriginal Peoples and Torres Strait Islander Peoples Driver Licensing Program to meet the needs of remote and Indigenous communities with significantly lower licence ownership levels.----- - Increased attention needs to focus on the contribution of geographic disadvantage (remoteness) factors to remote and Indigenous road trauma.----- + Road environment - Speed is the ‘final common pathway’ in determining the severity of rural and remote crashes and rural speed limits should be reduced to 90km/hr for sealed off-highway roads and 80km/hr for all unsealed roads as recommended in the Austroads review and in line with the current Tasmanian government trial.----- - The Department of Main Roads should monitor rural crash clusters and where appropriate work with local authorities to conduct relevant audits and take mitigating action. - The international experts at the workshop reviewed the data and identified the need to focus particular attention on road design management for dangerous curves. They also indicated the need to maximise the use of audio-tactile linemarking (audible lines) and rumble strips to alert drivers to dangerous conditions and behaviours.----- + Trauma costs - In accordance with Queensland Health priorities, recognition should be given to the substantial financial costs associated with acute management of trauma resulting from serious rural and remote crashes.----- - Efforts should be made to develop a comprehensive, regionally specific costing formula for road trauma that incorporates the pre-hospital, hospital and post-hospital phases of care. This would inform health resource allocation and facilitate the evaluation of interventions.----- - The commitment of funds to the development of preventive strategies to reduce rural and remote crashes should take into account the potential cost savings associated with trauma.----- - A dedicated study of the rehabilitation needs and associated personal and healthcare costs arising from rural and remote road crashes should be undertaken.----- + Emergency services - While the study has demonstrated considerable efficiency in the response and retrieval systems of rural and remote North Queensland, relevant Intelligent Transport Systems technologies (such as vehicle alarm systems) to improve crash notification should be both developed and evaluated.----- + Enforcement - Alcohol and speed enforcement programs should target the period between 2 and 6pm because of the high numbers of crashes in the afternoon period throughout the rural region.----- + Drink driving - Courtesy buses should be advocated and schemes such as the Skipper project promoted as local drink driving countermeasures in line with the very high levels of community support for these measures identified in the hospital study.------ - Programs should be developed to target the high levels of alcohol consumption identified in rural and remote areas and related involvement in crashes.----- - Referrals to drink driving rehabilitation programs should be mandated for recidivist offenders.----- + Data requirements - Rural and remote road crashes should receive the same quality of attention as urban crashes. As such, it is strongly recommended that increased resources be committed to enable dedicated Forensic Crash Units to investigate rural and remote fatal and serious injury crashes.----- - Transport department records of rural and remote crashes should record the crash location using the national ARIA area classifications used by health departments as a means to better identifying rural crashes.----- - Rural and remote crashes tend to be unnoticed except in relatively infrequent rural reviews. They should receive the same level of attention and this could be achieved if fatalities and fatal crashes were coded by the ARIA classification system and included in regular crash reporting.----- - Health, Transport and Police agencies should collect a common, minimal set of data relating to road crashes and injuries, including presentations to small rural and remote health facilities.----- + Media and community education programmes - Interventions seeking to highlight the human contribution to crashes should be prioritised. Driver distraction, alcohol and inappropriate speed for the road conditions are key examples of such behaviours.----- - Promotion of basic safety behaviours such as the use of seatbelts and helmets should be given a renewed focus.----- - Knowledge, attitude and behavioural factors that have been identified for the hospital Brief Intervention Trial should be considered in developing safety campaigns for rural and remote people. For example challenging the myth of the dangerous ‘other’ or ‘non-local’ driver.----- - Special educational initiatives on the issues involved in rural and remote driving should be undertaken. For example the material used by Main Roads, the Australian Defence Force and local initiatives.

When supply does not meet demand-ER stress and plant programmed cell death

The endoplasmic reticulum (ER) is the central organelle in the eukaryotic secretory pathway. The ER functions in protein synthesis and maturation and is crucial for proper maintenance of cellular homeostasis and adaptation to adverse environments. Acting as a cellular sentinel, the ER is exquisitely sensitive to changing environments principally via the ER quality control machinery. When perturbed, ER-stress triggers a tightly regulated and highly conserved, signal transduction pathway known as the unfolded protein response (UPR) that prevents the dangerous accumulation of unfolded/misfolded proteins. In situations where excessive UPR activity surpasses threshold levels, cells deteriorate and eventually trigger programmed cell death (PCD) as a way for the organism to cope with dysfunctional or toxic signals. The programmed cell death that results from excessive ER stress in mammalian systems contributes to several important diseases including hypoxia, neurodegeneration, and diabetes. Importantly, hallmark features and markers of cell death that are associated with ER stress in mammals are also found in plants. In particular, there is a common, conserved set of chaperones that modulate ER cell death signaling. Here we review the elements of plant cell death responses to ER stress and note that an increasing number of plant-pathogen interactions are being identified in which the host ER is targeted by plant pathogens to establish compatibility.

Queensland floods anniversary : Angela Emmerson

"We're marking the anniversary of the destructive floods that hit Queensland a year ago this week with our series of interviews from survivors. Today's story is from Helidon teenager and university student Angela Emmerson, who tells Amanda Gearing how she and her sister scrambled to the roof to escape the dangerous flash flood which suddenly engulfed their house on the 10th of January last year. Tomorrow we'll hear from Grantham resident Rob Wilkin who rescued 31 local people using his car and boat. He helped them escape to safety as 138 houses in the town were destroyed. To mark the anniversary of the floods in Queensland, ABC Open has compiled Aftermath, an extensive look at the Queensland floods as well as floods in NSW, Victoria and remote Western Australia; Cyclone Yasi and the 2009 Victorian 'Black Saturday' bushfires. Australia certainly has been hit by a few disasters in the past two or so years. The site has a timeline showing content from these six disasters, with links to about 40 people effected by these disasters. If you go to that site you will be able to choose a person to watch videos about them."

Vilijonkka ikkunassa - Tove Janssonin muumiteosten kuva, sana ja liike

Tove Jansson (1914--2001) was a Finnish illustrator, author, artist, caricaturist and comic artist. She is best known for her Moomin Books, written in Swedish, which she illustrated herself, and published between 1945 and 1977. My study focuses on the interweaving of images and words in Jansson s picturebooks, novels and short stories situated in the fantasy world of Moomin Valley. In particular, it concentrates on Jansson s development of a special kind of aesthetics of movement and stasis, based upon both illustration and text. The conventions of picturebook art and illustration are significant to both Jansson s visual art and her writing, and she was acutely conscious of them. My analysis of Jansson s work begins by discussing her first published picturebooks and less familiar illustrations (before she began her Moomin books) and I then proceed to discuss her three Moomin picturebooks, The Book about Moomin, Mymble and Little My; Who Will Comfort Toffle?, and The Dangerous Journey. The discussion moves from images to words and from words to images: Barthes s (1982) concept of anchoring and, in particular, what he calls relaying , form a point of reading and viewing Moomin texts and illustrations in a complementary relation, in which the message s unity occurs on a higher level: that of the story, the anecdote, the diegesis . The eight illustrated Moomin novels and one collection of short stories are analysed in a similar manner, taking into account the academic discourse about picturebooks which was developed in the last decade of the 20th century and beginning of the 21st century by, among others, scholars such as Nodelman, Rhedin, Doonan, Thiele, Stephens, Lewis, Nikolajeva and Scott. In her Moomin books, Jansson uses a wide variety of narrative and illustrative styles which are complementary to each other. Each book is different and unique in its own way, but a certain development or progression of mood and representation can be seen when assessing the series as a whole. Jansson s early stories are happy and adventurous but her later Moomin novels, beginning from Moominland Midwinter, focus more on the interiority of the characters, placing them in difficult situations which approximate social reality. This orientation is also reflected in the representation of movement and space. The books which were published first include more obviously descriptive passages, exemplifying the tradition of literary pictorialism. Whereas in Jansson s later work, the space develops into something that is alive which can have an enduring effect on the characters personalities and behaviour. This study shows how the idea of an image a dynamic image -- forms a holistic foundation for Jansson s imagination and work. The idea of central perspective, or frame, for instance, provided inspiration for whole stories or in the way that she developed her characters, as in the case of the Fillyjonk, who is a complex female figure, simultaneously frantic and prim. The idea of movement is central to the narrative art of picturebooks and illustrated texts, particularly in relation to the way that action is depicted. Jansson, however, also develops a specific choreography of characters in which poses and postures signify action, feelings and relationships. Here, I use two ideas from modern dance, contraction and release (Graham), to characterise the language of movement which is evident in Jansson s words and images. In Jansson s final Moomin novels and short stories, the idea of space becomes more and more dynamic and closely linked with characterisation. My study also examines a number of Jansson s early sketches for her Moomin novels, in which movement is performed much more dramatically than in those illustrations which appeared in the last novels to be published.

Ele está presente: a obra de Silviano Santiago e as performances do artista perigoso

A presente dissertação tem como objetivo refletir sobre a imagem do artista na obra de Silviano Santiago, mais precisamente sobre a figura do narrador-escritor da novela Uma história de família (1992), em abordagem comparativa com outros artistas, cuja produção e aparecimento na mídia problematizaram as primeiras décadas do HIV/AIDS, tais como Cazuza e o artista visual Leonilson, que posavam midiaticamente como perigosos. Pretende-se apontar, na obra de Silviano Santiago, uma performance do artista (soropositivamente) perigoso, na qual a relação entre enfermidade, dor, prazer e labor literário é verificável. Outros artistas são estudados, tais como o escritor Jean-Claude Bernardet, a artista visual Teresa Margolles e o performer Ron Athey, assim como os já citados Cazuza e Leonilson. Partindo da tese de Doutorado e da dissertação de Mestrado de Marcelo Secron Bessa, este trabalho procura avançar com algumas questões que, para tanto, recorrem ao conceito de performatividade, em Judith Butler, à noção do corpo como um Outro radical, de Henri-Pierre Jeudy, e à análise da relação entre AIDS e a discursividade empreendida por Susan Sontag. Os textos críticos de Silviano Santiago também fundamentam o presente estudo, mais precisamente na análise daqueles da relação entre dor e prazer na criação literária e da noção de uma homossexualidade astuciosa em resposta às discursividades heteronormativas

Quando os médicos julgam e os juízes tratam psiquiatria e normalização no sistema penal brasileiro

Esta dissertação discute as funções desempenhadas pelo psiquiatra no sistema penal brasileiro, que são a assistência aos transtornos mentais, a avaliação da responsabilidade sobre um ato delituoso e a elaboração de laudos para a concessão do benefício da libertação progressiva a presos comuns. São apresentados os impasses advindos do contato entre justiça e ciência, demonstrando-se como, nos dois últimos casos, o psiquiatra não lida com seu objeto habitual, o doente mental, mas com um outro diverso, o indivíduo perigoso. Para conhecer e controlar este novo objeto a psiquiatria forma, junto com o judiciário, um outro poder denominado, conforme Michel Foucault, normalizador que, sob uma ótica genealógica, transcende o seu objeto original, transformando-se em meio de controle de todo o corpo social. Tendo por principal referencial teórico a obra daquele pensador francês, notadamente os textos vindos à luz nos últimos anos, com a publicação da transcrição de cursos e de outros artigos dispersos, este mecanismo de controle social é analisado, discutindo-se as transformações por que vem passando nas últimas décadas. Paralelamente, é defendida a extinção da necessidade do referendo psiquiátrico à progressão do regime prisional, como forma de corrigir um sistema que não funciona satisfatoriamente.

O outro lado de uma política de governo na reprodução e perpetuação de desumanidades: o recolhimento de crianças e adolescentes em situação de rua na cidade do Rio de Janeiro

Esta dissertação de mestrado trata da prática do recolhimento de crianças e adolescentes em situação de rua, na cidade do Rio de Janeiro, como um tipo de política de governo que vem reproduzindo e perpetuando um estado de barbárie, intolerância e desumanidade junto a esse segmento da população. A contextualização deste fenômeno é feita durante o período que vai de 2001 a 2011 marco dos 10 anos de constituição da Rede Rio Criança na cidade do Rio de Janeiro, e das gestões do Prefeito César Maia (2001 a 2009), e os 02 primeiros anos da gestão de Eduardo Paes na Prefeitura do Rio (2010 -2011). Para uma análise mais aprofundada, é importante nos reportarmos à história recente para entendermos melhor o desenvolvimento deste fenômeno e o seu processo contraditório, que tem no sistema capitalista o aprofundamento das desigualdades e da intolerância, a produção de subjetividades sobre o jovem perigoso, e a perpetuação de práticas de controle e repressão direcionadas aos pobres. Nesse processo, observamos a manutenção de práticas retrógradas inspiradas no higienismo e eugenia. Procuro também trazer minha implicação com essa história, e dialogar com alguns autores, trabalhando certas categorias para ajudar na construção do objeto. Como estes fatos foram sendo histórica, social e culturalmente construídos e ainda nos constituem no presente, que tipo de racionalidade está presente, saber o que esses meninos e meninas, vítimas das operações de recolhimento, sentem, de que forma estas práticas os afeta e quais são as conseqüências em suas vidas, são questões importantes trabalhadas nesta pesquisa.

Statistical approach to bulk inclusion initialized damage in films

In experiments, we have found an abnormal relationship between probability of laser induced damage and number density of surface inclusion. From results of X-ray diffraction (XRD) and laser induced damage, we have drawn a conclusion that bulk inclusion plays a key role in damage process. Combining thermo-mechanical damage process and statistics of inclusion density distribution, we have deduced an equation which reflects the relationship between probability of laser induced damage, number density of inclusion, power density of laser pulse, and thickness of films. This model reveals that relationship between critical sizes of the dangerous inclusions (dangerous inclusions refer to the inclusions which can initialize film damage), embedded depth of inclusions, thermal diffusion length and tensile strength of films. This model develops the former work which is the statistics about surface inclusion. (c) 2006 Elsevier B.V. All rights reserved.
