Reconhecimento e vida dos guardas municipais : clínica do trabalho na atividade de segurança pública

Castro, Thiele da Costa Muller January 2010 (has links)
Cette étude a comme intention la recherche des sujets relatifs au travail et à la santé mentale et comme objet de recherche la reconnaissance du travailleur. Il se base dans l’importance de la compréhension du dynamique plaisir et souffrance psychique trouvée dans les relations de travail, en ayant comme objectif enquêter les formes de reconnaissance des gardes municipales, ainsi qu’analyser les stratégies de défense construites pour la confrontation du quotidien du travail. Le champ de recherche a été la Garde Municipale de Porto Alegre - GMPA, plus spécifiquement le Groupement Spécial Motorisé - GEM. Les sujets de recherche, les gardes municipaux, sont des travailleurs qui ont comme activité la sécurité urbaine. La méthodologie utilisée pour la recherche est la Psychodynamique du Travail, qui se propose, à travers l’écoute et la parole, comprendre l’organisation du travail et l’efficacité des stratégies, en analysant la parole et en écoutant la souffrance. Avec cette étude il s’est vérifié que les gardes municipales se perçoivent reconnus, mais, pour que cela se produise, investissent dans son travail et dans les formes de manutention du même, comme dans des uniformes et dans la différenciation du groupe et de leurs fonctions. Ce a aussi été possible d’appréhender les aspects subjectifs et objectifs des quotidien du travail des gardes municipales et les stratégies qu’ils construisent pour se maintenir dans un état de normalité. / Este estudo tem como propósito de investigação os temas relativos ao trabalho e à saúde mental, e como objeto de pesquisa o reconhecimento do trabalhador. Fundamenta-se na importância da compreensão da dinâmica prazer e sofrimento psíquico encontrada nas relações de trabalho, tendo como objetivo investigar as formas de reconhecimento dos guardas municipais, bem como analisar as estratégias defensivas construídas para o enfrentamento do cotidiano do trabalho. O campo de pesquisa foi a Guarda Municipal de Porto Alegre – GMPA, mais especificamente o Grupamento Especial Motorizado - GEM. Os sujeitos da pesquisa, guardas municipais, são trabalhadores que têm como atividade a segurança urbana. A metodologia utilizada para a pesquisa foi a Psicodinâmica do Trabalho, que se propõe, através da escuta e da fala, a saber sobre a organização do trabalho e sobre a eficácia das estratégias, analisando a fala e escutando o sofrimento. Com este estudo verificou-se que os guardas municipais percebem-se reconhecidos, mas para que isso ocorra investem em seu trabalho e nas formas de manutenção do mesmo, como em uniformes e na diferenciação do grupo e de suas funções. Também foi possível apreender os aspectos subjetivos e objetivos do cotidiano do trabalho dos guardas municipais e as estratégias que constroem para se manterem em uma normalidade sofrente. / This study aims to research the issues relating to work and mental health, and the purpose is worker acknowledgment. It is based on the importance of understanding the dynamics of pleasure and psychological suffering found in labor relations and to investigate the ways of acknowledgment of the municipal guards as well as analying the defensive strategies created to face everyday challenges at work. The research field as the Guard Hall of Porto Alegre – GMP, more specifically the Special Motorized Reverse - GEM. The subjects, municipal guards, are workers who have the activity of urban safety. The methodology for the research was the psychodynamics at work which aims, through listening and speaking, to know about the organization of work and the effectiveness of the strategies, analyzing the speech and listening to the suffering. This study found that the city police officers feel themselves acknowledged, but to have that they invest in their work and in the ways of maintaining it as in uniforms and in the differentiation of the group and its functions. It was possible to appreciate the objective and the subjective aspects of the daily work of these city police oficcers and strategies that they create to keep themselves as normal sufferers.

[en] PARENTAL ALIENATION: CONFLICT, VIOLENCE AND SHARED CUSTODY / [pt] ALIENAÇÃO PARENTAL: CONFLITO, VIOLÊNCIA E GUARDA COMPARTILHADA

DEBORA AUGUSTO FRANCO 11 February 2019 (has links)
[pt] O presente estudo teve como objetivo investigar a vivência de pais que lutam pela guarda compartilhada. Foram entrevistados 12 sujeitos, dez homens e duas mulheres, recrutados diretamente em comunidades virtuais do facebook que atuam como grupos de apoio para pais que lutam na justiça para obter a guarda compartilhada dos filhos. Como instrumento de investigação, utilizou-se uma entrevista online com roteiro semiestruturado, contendo questões abertas. O texto dos entrevistados, registrado por meio do Messenger, foi submetido ao método de análise de conteúdo na sua vertente categorial temática. A partir das narrativas, emergiram sete categorias de análise: Conflitos relativos ao litígio conjugal; Conflitos conjugais que afetam o cotidiano familiar e o relacionamento pais e filhos; Violência doméstica associada ao rompimento da relação conjugal; Prioridade da guarda materna; Guarda compartilhada como alternativa para a convivência familiar; Alienação Parental; e Criminalização da alienação parental. A categoria Violência doméstica associada ao rompimento da relação conjugal foi desdobrada em três subcategorias: Justificativas para a violência conjugal: ameaça, vingança e traição; Violência sexual associada ao rompimento conjugal; e Presença dos filhos em situações de violência associada ao rompimento conjugal. Esse estudo foi apresentado no formato de quatro artigos. A partir dos resultados da pesquisa, concluímos que quando os conflitos conjugais persistem pós-divórcio, e são manifestados por meio de desejo de vingança e violência, os cuidados parentais são prejudicados. Nesse contexto, engendram-se diferentes fenômenos que podem marcar a luta pela guarda compartilhada nas famílias pós-divórcio, tais como: violência doméstica e intrafamiliar como modelo de identificação para os filhos; padrões de provisão e cuidado atrelados às figuras de pai e mãe, respectivamente; expressão da lide na vivência de alienação parental; e perpetuação do litígio encoberto na luta por direitos e expressa na judicialização das relações familiares. Os desdobramentos da separação conjugal conflituosa podem afetar a relação entre pais e filhos, comprometendo o desenvolvimento infantil, o direito dos filhos à convivência familiar e a manutenção dos vínculos parentais após o rompimento da relação conjugal. Ademais, destaca-se a importância da criação de serviços públicos especializados no atendimento às questões relativas ao divórcio litigioso e às situações de violência associadas ao fim da relação amorosa como forma de enfrentamento das questões que atravessam a relação parento-filial nas famílias pós-divórcio. / [en] The purpose of this study is to investigate the experience of divorced parents who fight for the shared custody of their children. The authors interviewed 12 subjects – 10 men and 2 women – the authors recruited participants online, from Facebook pages that serve as a support network for parents who fight in the legal system for the shared custody of their children. As an investigative tool, was used an online interview with open questions. The participants words, registered in the Messenger app, were submitted to the content analysis method in its thematic category model. From the narratives, seven categories of analysis emerged: Conflicts relating to marital litigation; Marital conflicts affecting the family routine, as well as the parent and children s relationship; Domestic violence associated with the breakup of the marital relationship; Priority the of maternal unilateral guard; Shared custody as an alternative to family living; Parental Alienation; and Criminalization of parental alienation. The category Domestic violence associated with the breakup of the marital relationship was divided into three subcategories: Justifications for marital violence: threat, revenge and cheating; Sexual violence associated with marital breakdown; and Presence of children in violence situations associated with marital breakdown. This study was presented in the format of four articles. From the results of the research, we conclude that when marital conflicts persist post-divorce and are manifested through a desire for revenge and violence, parental s care is impaired. In this contexto, different phenomena are generated that can mark the struggle for shared custody in post-divorce families, such as: domestic and intrafamily violence as a model of identification for the children; concepts of provision and care linked to the father and mother figures, respectively; expression of the litigation in the experience of parental alienation; and perpetuation of the litigation, hidden in the struggle for rights and explicit in the judicialization of family relations. The unfolding of conflicting marital separation can affect the relationship between parents and children, jeopardizing healthy child development, the right of the children to family interaction and the maintenance of parental bonds after the conjugal relationship breakup. In addition, it is relevant to note the importance of creating public services specialized in dealing with issues related to divorce and situations of violence associated with the end of the love relationship as a way of coping with the issues that cross the parental-filial relationship in the post- divorce context.

People on the Edges of Dreams

French, Francesca B. 17 November 1995 (has links)
This thesis is composed of a collection of twelve short stories, varying in length from 2 to 14 pages. Each story contains its own discrete theme, but fits as well within the overarching theme of the collection as a whole. This overarching theme is what gives the collection its cohesiveness. The main theme of the larger work can be found in the title of the collection, People on the Edges of Dreams. In many of the stories dreams, or dream-states, figure in the lives of the protagonists. In addition to the dream-state theme there is a less obvious theme, which has to do with the extent to which most or all of the main characters in the stories are faced with a kind of inescapable compassion for others. For example, the selfinvolved, self-gratifying protagonist in Matador cannot help but feel compassion first for Pearl, the woman he insults, and second for the "bums" on whom his livelihood depends. The theme of inescapable compassion can, I believe, be found to varying degrees in each of the stories in this collection.

我國維護海上安全能量之研究 / Maintains research of the marine security energy in Taiwan

劉志慶 Unknown Date (has links)
進入全球化的21世紀,對於海上安全議題,個別國家已經無法獨自處理。海上安全議題所牽涉的範圍相當廣泛,尤其是必須面對傳統的與非傳統安全所交織而成的威脅,而這些威脅將對國家安全產生重大影響,因為海洋環境的安全,關係到世界各國的生存發展,如果海洋受到威脅,將對世界政治與經濟安全產生強烈衝擊,並嚴重危害人類社會秩序與穩定。 自1982年聯合國《海洋法公約》公布後,各沿海國家紛紛競逐海洋領土,引發區域內利益衝突,我國為一海洋國家,生存發展必須仰賴海上,當然也受到衝擊,舉凡海洋領土、海上交通、貿易、能源礦藏、漁業資源保育、環境保護等事項,均受到各國海權擴張的影響,囿於我國政治地位及地理環境的特殊性,周邊國家均不願正視我國的存在事實,加上專屬經濟海域與各國嚴重重疊因素,至今無法循正常外交管道協議劃界,進而衍生 “海洋領土爭議”、“漁權爭端”、“海域資源開發與探勘”及“海上犯罪”等影響我國家安全之問題。 目前各國在處理海洋爭端時,用和平與對話的方式是當今現代國家最高指導原則,但其核心仍然離不開海洋控制,所以發展強大的海上武裝力量仍將是實現海權必要步驟和標誌。但是,若動用海軍來處理海上非軍事面向的衝突時,將可能引發戰爭。因此,若要維護國家海權伸張以及降低軍事衝突的可能性,擁有一支足以擔負起海上安全任務、確保國家利益卻又不帶軍事色彩的海域執法機關是不可或缺的,惟有建構強大海上執法實力,我國海上安全與海洋權益才能獲得確保。本論文從中共、韓國、日本、菲律賓與越南等周邊國家,比較我國與各國在海洋事務之推展及海上執法機關能量之現況,發掘問題、分析檢討不足之處,進而提出符合我國國家安全與區域海上安全的對策。 / Maritime security is beyond the ability of each individual country in an era of globalization in 21st century as it involves extensive scope of topics especially for traditional and non-traditional threats they need to face, in which these threats will cause major impact on the national safety as the safety of marine environment is associated with survival and development of various countries in the world, there will be strong impact on the global politics, economy and safety and will severely endanger social order and stability of human beings once the ocean is being threatened. Since “Oceans and Law of the Sea”was announced by the United Nations in 1982, the various coastal countries have been competing for the marine territory and caused conflict of interests within the region, Taiwan is a marine country which relies on the sea for its survival and development and will by all means be affected. Those which are associated with marine territory, marine traffic, trade, energy & mineral resources, fishery resources care, environmental protection matters will be all affected by sea power expansion of various countries. Due to the particularity of our political status and geography, the peripheral countries all ignore the existence of Taiwan, and also, the territorial sea of Taiwan is overlapping with various countries, have led to unavailability of marking off the territory through normal diplomatic channels and further caused “sovereignty of marine territory dispute”, “fishing right dispute”, “resource development & investigation of territorial sea” and “cross-border” crime at sea and other issues that will affect our national security. Currently, the various countries follow principles of peace and conversation when dealing with maritime disputes and mainly stay with maritime control; therefore, developing strong marine force is necessary step to take and a symbol to realize sea power. However, it may cause war if using the navy to handle the non-military conflict at sea, therefore, it is indispensable to have a maritime law enforcement authority that is capability of taking the responsibility of maritime security, ensuring national interest without military influence if you’d like to protect the expansion of sea power of a nation and minimize the military conflict. Only having strong capability in maritime law enforcement will ensure maritime security and marine benefits of Taiwan, in which this paper proceeds comparisons of PRC, Korea, Japan, Philippines, Vietnam and other peripheral countries with Taiwan in terms of promotion of marine affairs and current situation of marine law enforcement authorities so as to discover problems, analyze shortcomings, and to further propose countermeasures that comply with our national security and regional maritime security.

Fragile mechanics : connecting Holocaust and art education through the creation of a graphic novel

Remington, Matthew Spencer 17 September 2013 (has links)
Through the creation of a graphic novel based on a Romanian Holocaust survivor’s testimony, this study attempts to clarify the role of artistic creation in meaning-making during Holocaust and genocide education. In facilitating empathy and moral education, the creative process encourages a deeper exploration of these troubling topics than is possible within the confines of a traditional academic approach. In order to understand this process, I worked with the testimony of Zoly Zamir, who escaped Bucharest following the Iron Guard Rebellion of 1941. The creation of the graphic novel took me from Austin to Houston and Romania, where I sought to trace the echoes of history in architecture and environment. Translating Zamir’s story into word and image produced an empathetic bond to the narrative and the region, facilitating a deeper understanding of the hows and whys of the Holocaust. That engagement spurred a desire to continue to ask questions, to look beyond a regimented understanding and view the broader implications of the history. / text

Statlig sjöfart för maritim säkerhet : och hur ser Försvarsmaktens roll ut? / States maritime authority’s for Maritime security : And what is the role of the Swedish Armed Forces?

Olsén, Fredrik January 2014 (has links)
Den statliga sjöfarten idag är ett område med många inblandade myndigheter och en oklar uppgiftsfördelning. Det är även svårt att se hur väl organiseringen av den statliga sjöfarten är uppbyggd för att klara en kris eller ett krig. Syftet med uppsatsen är att undersöka hur effektiv den statliga sjöfarten är vid en kris, hur väl kraven för maritim säkerhet uppfylls och hur försvarsmaktens roll i den statliga sjöfartenI formen av en fallstudie med en teoretiskt deduktiv ansats och en kvalitativ textanalys appliceras Graham Allisons organisationsteori och teori om maritim säkerhet på den statliga sjöfarten. Empirin är i form av förordningar, instruktioner och reglerbrev som är ställda på respektive myndighet.Undersökningen visar att dagens organisering av den statliga sjöfarten inte är optimal för att verka vid en kris och kraven för maritim säkerhet uppfylls, men förbättringspunkter föreligger. En slutsats är att en närmare samverkan mellan myndigheterna skulle lösa många av de problem som idag existerar. Slutligen förs en diskussion om hur en framtida organisation skulle kunna se ut. / The states maritime activity is today an area with many authorities involved with an unclear division of tasks. It is also difficult to see how well it is organized to withstand a crisis or war. The purpose of this paper is to examine how effective the states maritime authorities is in a crisis, how well the requirements for maritime security are met and how the Defense Forces role is formed.In the form of a case study with a theoretical deductive base and qualitative textual analysis, Graham Allison's organizational theory and theories of maritime security is used to analyze the efficiency of the maritime authorities. The empirical data is in the form of regulations, instructions and rules letters that are set to the each authority.The study shows that the current organization of the states maritime authorities is not optimal to act in a crisis and the requirements for maritime security are met, but room for improvement exists. One conclusion is that a closer collaboration between the authorities would solve many of the problems that currently exist. Finally there is a discussion of how a future organization could take shape.

Minion- en ordningsam vän i tvättstugan

Karlsson, Katerina January 2014 (has links)
Minion- en ordningsam vän i tvättstugan. Tvättstugan. En samhällstjänst som alla tar för givet eller en arena för dåligt beteende. Vad den än är så är den stället där beteenden som fusk med städning samt stulna tvättider och kläder sker vilket kan mynna ut i riktigt allvarliga bråk som polisanmäls. Att ändra på tvättstugan och hålla ett vakande öga över den kostar pengar och det har inte alla. Under dessa förhållanden kommer problemen som påträffas där, bara att fortsätta att existera tills alla tvättstugor stängs. Forskning har visat att bilder på ögon motarbetar beteenden som orsakar problem i tvättstugan. De skapar en omedveten känsla av övervakning som korrigerar beteenden genom medvetenheten om det dåliga beteendet, eller av rädslan att bli påkommen och bestraffad. När bilder på ögon har en så stor effekt på oss kommer en interaktiv robot försedd med ögon, röst och en snäll personlighet att ha samma effekt samt förstärka känslan av övervakning. Minion är en liten interaktiv robot som håller tvättstugans besökare sällskap och blir dess beskyddare. Minions huvuduppgift är att påminna tvättstugans besökare att de aldrig är ensamma där och därmed motarbeta dåligt beteende som förstärks på avskilda platser. Minion lyckas med det genom att kommunicera, sjunga, dansa, äta ludd från torktumlaren och berätta lite olika saker om världen och sitt eget liv. Till och med i sin tystnad orsakar Minion känslan av övervakning för den som vistas i tvättstugan. Tyvärr är den existerande prototypen bara ett skal och inte en funktionell robot, därför förklarades Minions funktioner muntligt och med hjälp av bilder under användarstudien. Minion mottogs med spänning och godkännande och det visade sig att Minions alla funktioer är relevanta och uppfylls till fullo. Minion skulle kunna vidareutvecklas till andra områden av vardagslivet där en interaktiv robot kan vara användbar, som att förbättra livskvaliteten för människor i behov av en kamrat. / Minion- an orderly friend in the common laundry room The common laundry room. A service to society that everyone takes for granted or an arena for bad behavior. In either case, it is a place where cheating with cleaning up after yourself as well as hijacking appointments and stealing other people’s belongings can lead to really serious fights that are reported to the police. Changing the common laundry room and keeping a waking eye on it, costs a lot of money something that not everyone has access to. Under these circumstances, the problems found there will simply go on existing until all common laundry rooms are shut down.  Research has proven that pictures of eyes can counter act behaviors similar to the ones causing trouble in the common laundry room. These pictures cause an unconscious feeling of being watched that will correct such behaviors either by creating consciousness of the bad behavior or the fear of being caught and then punished. As pictures of eyes have such a severe effect on us, an interactive robot with eyes, a voice and a kind personality will have the same effect as well as reinforce the feeling of being watched. Minion is a small interactive robot that keeps the common laundry room’s visitors company while being its patron. Minion’s main task is to remind the visitors that they are never there alone and can therefore counteract such bad behavior that is reinforced in secluded spaces. Minion succeeds in doing so by having the ability to communicate, sing, dance, eat fluff from the drier and recount facts about the world and its own life. Even while being silent it causes the same feeling of being watched for the ones being in the common laundry room with it. Unfortunately the existing prototype is that only of a shell and not a fully functional robot, as of which Minion’s functions had to be explained through pictures and reenactments during the user study that was made. Minion was embraced with excitement and approval and the case study proved that all of Minion’s functions are relevant as well as completely fulfilled. Minion could be further developed to other areas of daily life where an interactive robot could be of some use, such as in improving the quality of life for people in need of a companion.

A Detailed Analysis of Guard-Heated Wall Shear Stress Sensors for Turbulent Flows

Ale Etrati Khosroshahi, Seyed Ali 30 July 2013 (has links)
This thesis presents a detailed, two-dimensional analysis of the performance of multi-element guard-heated hot-film wall shear stress microsensors for turbulent flows. Previous studies of conventional, single-element sensors show that a significant portion of heat generated in the hot-film travels through the substrate before reaching the fluid, causing spectral and phase errors in the wall shear stress signal and drastically reducing the spatial resolution of the sensor. Earlier attempts to reduce these errors have focused on reducing the effective thermal conductivity of the substrate. New guard-heated microsensor designs proposed to overcome the severe deficiencies of the conventional design are investigated in this thesis. Guard-heaters remove the errors associated with substrate heat conduction, by forcing zero temperature gradient at the edges and bottom face of the hot-film, and hence, block the indirect heat transfer to the flow. Air and water flow over the sensors are studied numerically to investigate design, performance and signal strength of the guard-heated sensors. Our results show, particularly for measurements in low-conductivity fluids such as air, that edge guard-heating needs to be supplemented by a sub-surface guard-heater, to make substrate conduction errors negligible. With this two-plane guard-heating, a strong non-linearity in the standard single-element designs can be corrected, and spectral and phase errors arising from substrate conduction can be eliminated. / Graduate / 0548 / etrati@uvic.ca

Forward-Backward asymmetry in top pair production at the ILC

Amjad, Muhammad Sohail 04 February 2014 (has links) (PDF)
This thesis is done in the framework of the ILC. The determination of the electroweak couplings of the top quark, is one of the tasks at the ILC. The thesis is dedicated to the measurement of the Forward-backward asymmetry in top quark pairs, at 500 GeV, using two beam polarization configurations, in the fully hadronic decay channel. The top quark almost exclusively decays to a b quark and a W boson. The 6 jet final state is analyzed using full detector simulation. Two jets with highest b-tag are taken as b jets and the remaining four jets are used to reconstruct the W s. The identification of the top and anti-top quarks is done by using the vertex charge of the b quark. Precisions on the production cross sections are also calculated. This thesis also includes a chapter on the optimization of the Si-W Electromagnetic calorimeter of the International Large Detector (ILD), one of the two detectors at the ILC. The ECAL of ILD, will consist of alternate layers of Silicon and Tungsten, where Silicon layers are active layers, while Tungsten is passive material. The Silicon layers are divided into wafers, surrounded by guard rings, to avoid the leakage currents. The analysis is focused to optimize the guard ring size. The thesis is divided into 6 chapters. The first chapter gives a brief over view of the Standard Model. The second chapter is dedicated to the theoretical aspects of the top quark physics at the ILC. A detailed description of the ILD and its sub-detectors is given in the 3rd chapter. The 4th chapter presents the studies of the optimization of Si-W ECAL guard ring size. The 5th chapter contains the details of analysis of tt production at ILC, and measurement of the AFBt . The last chapter contains the summary of the results.
