Objectives. While older adults often display memory deficits, with practice they can sometimes selectively remember valuable information at the expense of less value information. We examined age-related differences and similarities in memory for health-related information under conditions where some information was critical to remember. Method. In Experiment 1, participants studied three lists of allergens, ranging in severity from 0 (not a health risk) to 10 (potentially fatal), with the instruction that it was particularly important to remember items to which a fictional relative was most severely allergic. After each list, participants received feedback regarding their recall of the high-value allergens. Experiment 2 examined memory for health benefits, presenting foods that were potentially beneficial to the relative’s immune system. Results. While younger adults exhibited better overall memory for the allergens, both age groups in Experiment 1 developed improved selectivity across the lists, with no evident age differences in severe allergen recall by List 2. Selectivity also developed in Experiment 2, although age differences for items of high health benefit were present. Discussion. The results have implications for models of selective memory in older age, and for how aging influences the ability to strategically remember important information within health-related contexts.

A discrete-time random process is described, which can generate bursty sequences of events. A Bernoulli process, where the probability of an event occurring at time t is given by a fixed probability x, is modified to include a memory effect where the event probability is increased proportionally to the number of events that occurred within a given amount of time preceding t. For small values of x the interevent time distribution follows a power law with exponent −2−x. We consider a dynamic network where each node forms, and breaks connections according to this process. The value of x for each node depends on the fitness distribution, \rho(x), from which it is drawn; we find exact solutions for the expectation of the degree distribution for a variety of possible fitness distributions, and for both cases where the memory effect either is, or is not present. This work can potentially lead to methods to uncover hidden fitness distributions from fast changing, temporal network data, such as online social communications and fMRI scans.

At the Paris Peace Conferences of 1918-1919, new states aspiring to be nation-states were created for 60 million people, but at the same time 25 million people found themselves as ethnic minorities. This change of the old order in Europe had a considerable impact on one such group, more than 3 million Bohemian German-speakers, later referred to as Sudeten Germans. After the demise of the Habsburg Empire In 1918, they became part of the new state of Czechoslovakia. In 1938, the Munich Agreement – prelude to the Second World War – integrated them into Hitler’s Reich; in 1945-1946 they were expelled from the reconstituted state of Czechoslovakia. At the centre of this War Child case study are German children from the Northern Bohemian town and district, formerly known as Gablonz an der Neisse, famous for exquisite glass art, now Jablonec nad Nisou in the Czech Republic. After their expulsion they found new homes in the post-war Federal Republic of Germany. In addition, testimonies have been drawn upon of some Czech eyewitnesses from the same area, who provided their perspective from the other side, as it were. It turned out to be an insightful case study of the fate of these communities, previously studied mainly within the context of the national struggle between Germans and Czechs. The inter-disciplinary research methodology adopted here combines history and sociological research to demonstrate the effect of larger political and social developments on human lives, not shying away from addressing sensitive political and historical issues, as far as these are relevant within the context of the study. The expellees started new lives in what became Neugablonz in post-war Bavaria where they successfully re-established the industries they had had to leave behind in 1945-1946. Part 1 of the study sheds light on the complex Czech-German relationship of this important Central European region, addressing issues of democracy, ethnicity, race, nationalism, geopolitics, economics, human geography and ethnography. It also charts the developments leading to the expulsion of the Sudeten Germans from Czechoslovakia after 1945. What is important in this War Child study is how the expellees remember their history while living as children in Sudetenland and later. The testimony data gained indicate that certain stereotypes often repeated within the context of Sudeten issues such as the confrontational nature of inter-ethnic relations are not reflected in the testimonies of the respondents from Gablonz. In Part 2 the War Child Study explores the memories of the former Sudeten war children using sociological research methods. It focuses on how they remember life in their Bohemian homeland and coped with the life-long effects of displacement after their expulsion. The study maps how they turned adversity into success by showing a remarkable degree of resilience and ingenuity in the face of testing circumstances due to the abrupt break in their lives. The thesis examines the reasons for the relatively positive outcome to respondents’ lives and what transferable lessons can be deduced from the results of this study.

This study investigated the effects of transporting animals from the experimental room to the animal facility in between experimental sessions, a procedure routinely employed in experimental research, on long-term social recognition memory. By using the intruder-resident paradigm, independent groups of Wistar rats exposed to a 2-h encounter with an adult intruder were transported from the experimental room to the animal facility either 0.5 or 6h after the encounter. The following day, residents were exposed to a second encounter with either the same or a different (unfamiliar) intruder. Resident`s social and non-social behaviors were carefully scored and subjected to Principal Component Analysis, thus allowing to parcel out variance and relatedness among these behaviors. Resident rats transported 6h after the first encounter exhibited reduced amount of social investigation towards familiar intruders, but an increase of social investigation when exposed to a different intruder as compared to the first encounter. These effects revealed a consistent long-lasting (24h) social recognition memory in rats. In contrast, resident rats transported 0.5 h after the first encounter did not exhibit social recognition memory. These results indicate that this common, little-noted, laboratory procedure disturbs long-term social recognition memory. (C) 2011 Elsevier B.V. All rights reserved.

Aromatherapy uses essential oils (EOs) for several medical purposes, including relaxation. The association between the use of aromas and a decrease in anxiety could be a valuable instrument in managing anxiety in an ever increasing anxiogenic daily life style. Linalool is a monoterpene commonly found as the major volatile component of EOs in several aromatic plant species. Adding to previously reported sedative effects of inhaled linalool, the aim of this study was to investigate the effects of inhaled linalool on anxiety, aggressiveness and social interaction in mice. Additionally, we investigated the effects of inhaled linalool on the acquisition phase of a step-down memory task in mice. Inhaled linalool showed anxiolytic properties in the light/dark test, increased social interaction and decreased aggressive behavior; impaired memory was only seen the higher dose of linalool. These results strengthen the suggestion that inhaling linalool rich essential oils can be useful as a mean to attain relaxation and counteract anxiety. (C) 2009 Elsevier GmbH. All rights reserved.

In this thesis, the basic research of Chase and Simon (1973) is questioned, and we seek new results by analyzing the errors of experts and beginners chess players in experiments to reproduce chess positions. Chess players with different levels of expertise participated in the study. The results were analyzed by a Brazilian grandmaster, and quantitative analysis was performed with the use of statistical methods data mining. The results challenge significantly, the current theories of expertise, memory and decision making in this area, because the present theory predicts piece on square encoding, in which players can recognize the strategic situation reproducing it faithfully, but commit several errors that the theory can¿t explain. The current theory can¿t fully explain the encoding used by players to register a board. The errors of intermediary players preserved fragments of the strategic situation, although they have committed a series of errors in the reconstruction of the positions. The encoding of chunks therefore includes more information than that predicted by current theories. Currently, research on perception, trial and decision is heavily concentrated on the idea of 'pattern recognition'. Based on the results of this research, we explore a change of perspective. The idea of 'pattern recognition' presupposes that the processing of relevant information is on 'patterns' (or data) that exist independently of any interpretation. We propose that the theory suggests the vision of decision-making via the recognition of experience.

This paper investigates the relationship between memory and the essentiality of money. We consider a random matching economy with a large finite population in which commitment is not possible and memory is limited in the sense that only a fraction m E(0; 1) of the population has publicly observable histories. We show that no matter how limited memory is, there exists a social norm that achieves the first best regardless of the population size. In other words, money can fail to be essential irrespective of the amount of memory in the economy. This suggests that the emphasis on limited memory as a fundamental friction for money to be essential deserves a deeper examination.

No Brasil, água e energia têm uma forte e histórica nterdependência, de forma que a contribuição da energia hidráulica ao desenvolvimento econômico do País tem sido expressiva, seja no atendimento às diversas demandas da economia, ou da própria sociedade, melhorando o conforto das habitações e a qualidade de vida das pessoas. Também desempenha papel importante na integração e desenvolvimento de regiões distantes dos grandes centros urbanos e industriais. A década de 70 registrou um crescimento elevado da demanda por energia elétrica no Brasil; reflexo de políticas desenvolvimentistas de governos anteriores que promoveram o crescimento industrial do País atraindo e criando indústrias de uso alto intensivo da letricidade. No caso da região Nordeste, o crescimento econômico trouxe consigo o risco de um grave racionamento de energia. Para eliminar tal risco, o Estado por intermédio do Sistema Eletrobras realizou a construção de grandes usinas hidrelétricas interligando-as ao sistema nacional. Não há como negar que esta solução provocou um grande benefício para grande parte da população brasileira, mas trouxe, para uma parcela do povo brasileiro, um custo social bastante elevado. Essas pessoas ficaram então conhecidas como os “atingidos por barragens”. Para eles, a construção das barragens de usinas como Itaipu, Tucuruí, Sobradinho e Itaparica significou o deslocamento compulsório dos locais aonde viviam e tinham suas tradições e referência culturais e afetivas. Esta pesquisa objetiva resgatar a memória deste período de grandes obras, promessas de desenvolvimento e marcas deixadas em milhares de famílias brasileiras. O estudo em questão é também uma tentativa de mostrar como o Programa de Reassentamento de Itaparica, projeto conduzido pela Companhia Hidro Elétrica do São Francisco – CHESF foi o marco de uma nova dinâmica para tratamento das questões sociais envolvendo a reparação de danos causados aos atingidos por barragens e se constitui talvez, no primeiro caso de Responsabilidade Social Corporativa do setor elétrico brasileiro.

Este trabalho é fruto de uma investigação realizada no doutorado em História, Política e Bens Culturais do Centro de Pesquisa e Documentação de História Contemporânea do Brasil da Fundação Getulio Vargas - orientada pela profa. Dra. Bianca Freire-Medeiros - acerca da constituição e implementação do turismo social no Serviço Social do Comércio do estado de São Paulo (Sesc-SP), examinando as circunstâncias em que o lazer e as experiências turísticas tornam-se relevantes nas políticas e ações da entidade. Procurou-se entender as transformações e readequações que nortearam as iniciativas da instituição e como as modificações no conceito de turismo social no Brasil e no mundo vêm dialogando com suas diretrizes, posturas e intenções. A metodologia privilegiada na pesquisa foi a história oral temática, no intuito de fazer o registro da história do envolvimento de profissionais com o turismo social do Sesc-SP. Foram realizadas vinte e duas entrevistas com (ex)profissionais e feitas algumas visitas à Biblioteca do departamento nacional do Sesc (Sesc-DN) e ao setor de memória e documentação (Sesc-Memórias) do departamento regional paulista do Sesc, lugares que congregam documentos importantes relacionados à história do turismo na instituição. Espacialmente a pesquisa situa-se no Sesc-SP, repartição atuante e “atenta” às ideias e mudanças envolvendo o turismo social, e representativa na história do fenômeno, no Brasil e no mundo. A circunscrição temporal da pesquisa abarca desde 1979 - ano em que o Sesc de São Paulo passa a desenvolver excursões, passeios e viagens com maior frequência e tenta se aprofundar conceitualmente do turismo social ao se aproximar de órgãos internacionais de relevância política e científica na área - até as ações realizadas em 2013, ano no qual termino a pesquisa de campo e as entrevistas. Durante a trajetória da pesquisa, dialoguei com o período que antecede este recorte, acerca dos empreendimentos do Sesc relacionados as práticas de lazer e turismo, gerando o capítulo 2. Antes, no capítulo 1, tentei reconhecer o lugar do turismo social na história das atividades turísticas no mundo, entendendo-o enquanto oportunidade de efetivação do direito ao lazer. Para alcance dos intentos da tese, como fontes foram utilizados documentos produzidos em âmbito institucional, articulados com a fala dos indivíduos entrevistados, trabalho conjugado especialmente no capítulo 3, em que trago reflexões a respeito do turismo social desenvolvido pelo Sesc-SP. Dentre as análises alvitradas, descrevo a dificuldade encontrada pela entidade ao expandir suas atividades turísticas, vindo a sofrer represálias do setor privado. Deve-se destacar que foi possível perceber a metamorfose conceitual/prática por qual passara o turismo social no Sesc-SP, agregando diferentes conteúdos ao fenômeno e modificando seus processos de trabalho e práticas profissionais. Ressalto ainda o papel ideológico da administração regional do Sesc-SP dentro do Serviço Social do Comércio no Brasil, notadamente na área do turismo. Por fim, envolvo no debate da tese as políticas sociais de turismo, compreendido enquanto possibilidade de lazer.

Esta tese tem como objetivo o estudo do processo de construção e apropriação do passado ferroviário e da transformação da memória ferroviária como objeto de política pública, sobretudo após a edição da Lei no 11.483/2007. O estudo aborda os papeis desempenhados por agentes sociais diversos, como as associações de preservação ferroviárias (APF), a Rede Ferroviária Federal (RFFSA) e o Instituto do Patrimônio Histórico e Artístico Nacional (Iphan), e suas estratégias de ressignificação e objetificação do passado ferroviário, processo que teve início ainda na década de 1970. A pesquisa descreve a implantação da malha ferroviária brasileira, de maneira a contextualizar a extinção da RFFSA, em 2007; aborda o surgimento e evolução das APFs, e descreve a atuação da Rede na preservação e salvaguarda do passado da ferrovia por meio da análise do Programa de Preservação do Patrimônio Histórico Ferroviário (Preserfe). Por fim, a tese se debruça sobre a atuação do Iphan, recorrendo à análise dos processos de tombamentos de bens ferroviários e ao estudo dos desdobramentos da Lei no 11.483/2007 no interior do órgão. O movimento de valorização do passado ferroviário contribui para os debates acerca dos processos de apropriação e patrimonialização do passado.
A Produção do Flagelo : a re-produção do espaço social da seca na cidade de Mossoró (1877-1903-1915)
Resumo:
The great droughts re- produced spaces in the city of Mossoró / RN in the end of the nineteenth century to the beginning of the twentieth century. Its dimension exceeds the climatic effects becoming social locus when advances over the political and economic sectors, social and cultural of the North / Northeast Brazilian societies during that period. This way, analyzing the re-production of social space in episodes of Mossoró‟s droughts is our toil. So try to reveal each segment, route and aspect of production of space in its size and interface between the perceived, conceived and lived, and subjects related to it - refugees, population and authorities - during the droughts of 1877, 1903 and 1915 within Mossoró city. Therefore, issues such as the constitution and representation of the city and social space in the terrifying experience of the drought of 1877, the production of fixed objects and flows of the urban web through of migrant labor, attempts to control, discipline and spatial planning and ways to resistance to these charges in daily sphere are key issues addressed in this work. For this we use diverse sources as minutes of the city council, reports from provincial presidents, media, memory books and others that sustain us in building our narrative and problematic. This way, the spatial production of Mossoró‟s droughts reveals itself in the field of relations and political-economic transformations and sociocultural, inextricably, that shapes and mobilizes your own social space

The study focuses on the psychology and Social Well-being Policy encounters. The objective is to understand how the psychologists in the health services of Natal, RN, specifically in the Basic Health Units and social assistance, experience their daily practices. The methodology included observation and interviews of 13 psychologists regarding their daily activities and forms of practice in these services. We utilized an interview protocol directed at the affective memory and the professional life history of these technicians. Field notes were used to produce a cartography of the encounter intensities experienced by the researcher in the investigated context. The data analysis enabled the construction of the following analytic axes: 1) Work processes and proximity/ distancing points between these fields; 2) Forms of government and life management in the well-being context; 3) Experiments of self in the daily services. The first axis showed the precariousness of working conditions (remuneration issues, lack of structure, of training and autonomy for the activities). In the second axis the identified care forms produced in these fields indicated an adherence to the production of ideal subjects characterized as autonomous, productive, healthy and aware of own rights . These were considered normative insofar as they express attempts to break with the established patterns. In the third axis, many technicians experienced constraint with the daily activities because they found themselves in contexts that were adverse to the habitual forms of action. This situation provoked two distinct forms of positioning: a) action expressed by compassion, pity and resentment; b) investment in the practices themselves, so as to overcome its limits and to respond innovatively to the difficulties and/or challenges that these contexts provoke
