More than thirty years of ultimatum bargaining experiments: Motives, variations, and a survey of the recent literature

Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss extensions of the standard ultimatum bargaining game in a unified framework, and, third, we offer a survey of the experimental ultimatum bargaining literature containing papers published since the turn of the century. The paper argues that the ultimatum game is a versatile tool for research in bargaining and on social preferences. Finally, we provide examples for open research questions and directions for future studies.

Knowledge through Discussion : An Interpretation of Epistemology in Plato's Meno

According to Meno s paradox we cannot inquire into what we do not know because we do not know what we are inquiring into. There are many ways to interpret the paradox but the central issue about our ability to reach truth is a profound one. In the dialogue Meno, Plato presents the paradox and an outline of a solution which enables us to reach knowledge (epistēmē) through philosophical discussion. During the last century Meno has often been considered transitional between Socratic thinking and Plato s own philosophy, and thus the dialogue has not been adequately interpreted as an integrated whole. Therefore the distinctive epistemology of the dialogue has not gained due notice. In this thesis the dialogue is analysed as an integrated whole and the philosophical interpretation also takes into account its dramatic features. The thesis emphasises the role of language and definitions in acquiring knowledge. Among the results concerning these subjects is a new interpretation of Socrates s defintion of shape (schēma). The theory of anamnēsis all learning is recollection in the Meno is argued to answer the paradox philosophically although Plato s presentation also contains playful and ironic elements. The background of the way Plato presents his case is that he appreciated the fact that no argument can plausibly demonstrate that argumentation is able to reach truth. In the Meno, Plato makes the earliest explicit distinction between knowledge and true belief in the history of Western philosophy. He also gives a definition of knowledge which is the basis of the so called classical definition of knowledge as justified true belief. In the Meno, true beliefs become knowledge when someone ties them down by reasoning about the explanation. The analysis of the epistemology of the dialogue from this perspective gives an interpretation which integrates the central concepts of the epistemology in the dialogue elenchos, anamnēsis and hypothetical inquiry into a unified whole which contains a plausible argument according to which the ignorant can reach knowledge through discussion. The conception that emerges by such an analysis is interesting both from the point of view of current interests and that of the history of philosophy. The method of knowledge acquisition in the Meno can, for example, be seen as a predecessor of modern scientific methods. The Meno is the earliest Greek mathematical text that has survived in its original form. The analysis presented in the thesis of the geometric passages in the dialogue provides new results both concerning Socrates s geometry lesson with the slave and the example presenting the hypothetical method. Concerning the latter, a new interpretation is presented. Keywords: anamnēsis, epistēmē, knowledge, Meno s paradox, Plato

Elämän ja entisyyden maisemat : Kolgujev nenetsien arjessa, muistelussa ja kerronnassa

The dissertation discusses the conceptions of place and landscape amongst Nenets living on the island of Kolguyev or being of Kolguyev descent. The conceptions are examined through the everyday life of the community, oral recollections and narration that unfold meanings related to the island. The research material has been collected in ethnographic fieldwork in 2000 2005. The duration of individual fieldworks varies from two weeks to three months and their total duration is nearly six months. The fieldwork has been conducted both on the island and in the city of Nar yan-Mar. The main methods have been participant observation and recorded and unrecorded informal interviews. In addition to the field work data, archive materials, travel accounts, and other historical texts by outsiders about Kolguyev or the Nenets living in the European side of Russia have been used as a research material. The analysis is based on the idea of the place as a meeting point of the physical features, experiences in them and collective narration about them. The concept sense of place is used to describe the interaction of these three. Lived space manifests individual s or collective sense of place. The places form different kinds of networks of meanings which are called landscapes. Hot spots are places where different meanings accumulate. Furthermore, the material is analysed using the concepts of Tale World and Story Realm by Katherine Young. The Tale World is a realm created during the Story Realm, i.e. the event of narrations. The Tale Worlds are true as such but become evaluated in the Story Realm. The Tale Worlds are seen to arise both from the physical features of a place and from oral tradition, but at the same time these worlds give meanings to the place. The Tale Worlds are one of the central ingredients for the sense of place. One of the most central hot spots in Kolguyev is the arok harbour, where most of the themes of the pre-Soviet Tale Worlds are placed: trade and interaction with the Russians, rituals of the popular religion and arrival of the first Nenets to the island. arok is also part of the landscape of the coast where the meetings of Nenets and the other(s) are generally connected. Furthermore, arok is connected to the network of amans graves but also more generally to the landscape of collective sacred and sacrificial places. Another hot spot is the population centre of Bugrino which unfolds through the evaluations of the Tale Worlds. It also is the centre of the everyday life of the community studied. The Tale Worlds of the radiant past fastens on the population centre which is described through the negative models within the genre of litany. Sacred places, that represent the possibility to meet the Otherworld or mark places were encounters with the Otherworld have taken place, generate many kinds of landscapes in the island. They fasten on the graves of the amans, sirtya tradition, and to collective sacred places with their associations. The networks are not closed systems but are given meanings and new associations continuously in narration and recollection. They form multi-level and significant landscapes which reflect the fastening of the Kolguyev Nenets in the tundra of the island. In the research material the holy places and the popular religiousness are emphasised which is one of the most significant research results. It can be seen to reflect collective resistance and the questioning of the atheistic propaganda of the Soviet years. The narration and the recollection often refer also to the discourse of the anti-religious propaganda or use its strategies. The centrality of the holy places is also based on the tenacity of the religious Tale Worlds and sense of place and to the collective significance of the religion in general.

Análise histórica das políticas de planejamento familiar no Brasil

O objetivo desta tese é traçar um panorama histórico das políticas públicas de planejamento familiar do Estado brasileiro, inserindo-o no contexto da complexa conjuntura sociopolítico-econômica no período de 1980 até a atualidade. Mediante pesquisa bibliográfica e documental, investigam-se, na interseção das políticas para população, mulher e saúde, as influências e interesses que incidem sobre programas de planejamento familiar. Após recuperar brevemente a trajetória dos movimentos de mulheres e feministas, que constituíram atores sociais centrais no debate sobre as políticas de população e de planejamento familiar, focaliza-se a drástica redução nas taxas de fecundidade da mulher brasileira ocorrida a partir dos anos 1960, na vigência oficial de uma política natalista, mas na omissão do Estado ao permitir a difusão no país de organizações de cunho controlista, que viabilizaram às mulheres o acesso à pílula anticoncepcional e à esterilização. Acompanha-se a evolução das políticas de população em nível mundial, destacando a atuação da Organização das Nações Unidas e de suas conferências mundiais, focalizando a Conferência Internacional de População e Desenvolvimento realizada no Cairo em 1994, que provocou uma inflexão nas políticas de saúde da mulher para saúde reprodutiva. No Brasil, que já contava com um programa pioneiro de saúde da mulher o Paism (1983) , os efeitos do Cairo vieram somar-se à definição do planejamento familiar pela Constituição de 1988 e à instituição do Sistema Único de Saúde em 1990. A análise permitiu identificar as influências externas e internas que incidem sobre a política de planejamento familiar. A política de planejamento familiar do país hoje configura-se democrática, abrangente e descentralizada, sendo a principal tensão identificada entre seus enunciados e sua implementação na prática, ou seja, só será efetiva se houver um controle social eficaz.

A pré-história e reencontro com o tempo em Sem tecto, entre ruínas de Augusto Abelaira

O presente trabalho consiste em um estudo crítico do romance Sem tecto, entre ruínas, de Augusto Abelaira. Inicialmente é feita a análise sobre as possíveis consequências de uma apreensão descontínua e material do tempo, seus efeitos nas relações entre o protagonista e seu mundo, que se apresentam sob a forma de tédio e paralisia. Para a crítica proposta foram retomados conceitos descontinuidade e homogeneidade apresentados pelo filósofo Henri Bergson, além da noção de desligamento e desejo demonstrados pela sociologia de Zigmunt Bauman. O próximo alvo contemplado na pesquisa é a presença da memória e da lembrança indicados sob o ponto de vista contínuo do tempo, também analisados à luz da filosofia de Bergson, além do pensamento de Gilles Deleuze. A partir desse caminho investigativo é possível pensar a condição do protagonista como um confronto de si, uma experiência do tempo que traz uma revelação mediante a condição de ser tarde demais

Do imaginário à narrativa: a memória da casa da infância

A casa da infância é uma entidade bipartida: uma, a casa vivida na experiência indiferenciada de ser, um lugar-tempo do inaugural, do espanto, do afeto; outra, aquela que este lugar-tempo produz no imaginário daquele que dela se afastou, geográfica e temporalmente, a casa onírica. No sujeito, memória e imaginação não se dissociam, e somente assim é possível retornar ao lugar-tempo mítico desta casa primeva; a memória é então fonte (ou ponte) para esta celebração da ausência retornada viva através da transmutação da lembrança em narrativa processo constante nos indivíduos que as obras ficcionais buscam reproduzir. A presente tese, Do imaginário à narrativa: a memória da casa da infância, pretende explorar a memória da casa e a ficção indissociável a esta na construção de um pre-texto gerador de narrativa no sujeito e a forma como este processo é ficcionalizado em produções literárias contemporâneas que recorrem a ela como temática e estrutura

Erros pré-analíticos em medicina laboratorial: uma revisão sistemática

MENEZES, Patrick Lourenço. Erros pré-analíticos em medicina laboratorial: uma revisão sistemática. 2013. 98 f. Dissertação (Mestrado em Saúde, Medicina Laboratorial e Tecnologia Forense) - Instituto de Biologia Roberto Alcântara Gomes, Universidade do Estado do Rio de Janeiro, Rio de Janeiro, 2013. A relevância evidente dos erros pré-analíticos como problema de saúde pública fica patente tanto no dano potencial aos pacientes quanto nos custos ao sistema de saúde, ambos desnecessários e evitáveis. Alguns estudos apontam que a fase pré-analítica é a mais vulnerável a erros, sendo responsável por, aproximadamente, 60 a 90% dos erros laboratoriais em consequência da falta orientação aos pacientes sobre os procedimentos que serão realizados no laboratório clínico. Objetivos: Sistematizar as evidências científicas relacionadas aos erros pré-analíticos dos exames laboratoriais de análises clínicas. Método: Uma revisão sistemática foi realizada, buscando as bases de dados do Medical Literature Analysis and Retrieval System Online (MEDLINE), Scopus(que inclui MEDLINE e Embase), ISI Web of Knowledge, SciFinder, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) (que inclui a Scientific Electronic Library Online SciELO) e o Índice Bibliográfico Espanhol de Ciências de Saúde (IBECS), para artigos publicados entre janeiro de 1990 e junho de 2012 sobre erros de exames laboratoriais que possam ocorrer na fase pré-analítica. Os estudos foram incluídos de acordo com os seguintes exames laboratoriais: hemograma, análise bioquímica do sangue total ou do soro, exames de coagulação sanguínea,uroanálise e exames hematológicos ou bioquímicos em outros materiais e categorizados pelo tipo de erro pré-analítico e pela frequência dos incidentes. Resultados: A busca nas bases de dados bibliográficas resultou no seguinte número de artigos recuperados: 547 na MEDLINE, 229 na Scopus, 110 na ISI, 163 na SciFinder, 228 na Lilacs e 64 na IBECS, perfazendo um total de 1.341 títulos. Ao fim da revisão sistemática, obteve-se um conjunto de 83 artigos para leitura de texto completo, dos quais 14 foram incluídos na revisão. Os estudos abrangeram diferentes tipos de laboratórios, setores técnicos e origem de erros, segundo a fase do processo laboratorial. Discussão: Sete artigos demonstraram erros de pedidos médicos, com uma alta variabilidade nos valores de incidência. Os seis artigos que estudaram erros de coleta de amostra observaram redução deste desfecho. As proporções de eventos adversos relatados e os impactos clínicos variaram, levando a consequências descritas como: erros decorrentes da flebotomia, recoleta de amostras, repetições de exames, atrasos na liberação de resultados de exames e possíveis danos ao paciente. Conclusões: O laboratório deve ter instruções por escrito para cada teste, que descreva o tipo de amostra e procedimento de coleta de amostra. Meios de identificação por código de barras, sistemas robóticos e analíticos reduzem os erros pré-analíticos. A melhoria da fase pré-analítica de testes laboratoriais permanece um desafio para muitos laboratórios clínicos.

获取无意识结构知识的机制:主观熟悉感与刺激重复结构在人工语法学习中的作用

The nature of the distinction between conscious and unconscious knowledge is a core issue in the implicit learning field. Furthermore, the phenomenological experience associated with having knowledge is central to the conscious or unconscious status of that knowledge. Consistently, Dienes and Scott (2005) measured the conscious or unconscious status of structure knowledge using subjective measures. Believing that one is purely guessing when in fact one knows indicates unconscious knowledge. But unconscious structural knowledge can also be associated with feelings of intuition or familiarity. In this thesis, we explored whether phenomenological feelings, like familiarity, associated with unconscious structural knowledge could be used, paradoxically, to exert conscious control over the use of the knowledge, and whether people could obtain repetition structure knowledge. We also investigated the neural correlates of awareness of knowing, as measured phenomenologically. In study one, subjects were trained on two grammars and then asked to endorse strings from only one of the grammars. Subjects also rated how familiar each string they felt and reported whether or not they used familiarity to make their grammaticality judgment. We found subjects could endorse the strings of just one grammar and ignore the strings from the other. Importantly, when subjects said they were using familiarity, the rated familiarity for test strings consistent with their chosen grammar was greater than that for strings from the other grammar. Familiarity, subjectively defined, is sensitive to intentions and can play a key role in strategic control. In study two, we manipulated the structural characteristic of stings and explored whether participants could learn repetition structures in the grammatical strings. We measured phenomenology again and also ERPs. Deviant letters of ungrammatical strings violating the repetition structure elicited the N2 component; we took this to be an indication of knowledge, whether conscious or not. Strings which were attributed to conscious categories (rules and recollection) rather than phenomenology associated with unconscious structural knowledge (guessing, intuition and familiarity) elicited the P300 component. Different waveforms provided evidence for the neural correlates of different phenomenologies associated with knowledge of an artificial grammar.

Dynamic neural networks supporting memory retrieval.

How do separate neural networks interact to support complex cognitive processes such as remembrance of the personal past? Autobiographical memory (AM) retrieval recruits a consistent pattern of activation that potentially comprises multiple neural networks. However, it is unclear how such large-scale neural networks interact and are modulated by properties of the memory retrieval process. In the present functional MRI (fMRI) study, we combined independent component analysis (ICA) and dynamic causal modeling (DCM) to understand the neural networks supporting AM retrieval. ICA revealed four task-related components consistent with the previous literature: 1) medial prefrontal cortex (PFC) network, associated with self-referential processes, 2) medial temporal lobe (MTL) network, associated with memory, 3) frontoparietal network, associated with strategic search, and 4) cingulooperculum network, associated with goal maintenance. DCM analysis revealed that the medial PFC network drove activation within the system, consistent with the importance of this network to AM retrieval. Additionally, memory accessibility and recollection uniquely altered connectivity between these neural networks. Recollection modulated the influence of the medial PFC on the MTL network during elaboration, suggesting that greater connectivity among subsystems of the default network supports greater re-experience. In contrast, memory accessibility modulated the influence of frontoparietal and MTL networks on the medial PFC network, suggesting that ease of retrieval involves greater fluency among the multiple networks contributing to AM. These results show the integration between neural networks supporting AM retrieval and the modulation of network connectivity by behavior.

The temporal distribution of autobiographical memory: changes in reliving and vividness over the life span do not explain the reminiscence bump.

When autobiographical memories are elicited with word cues, personal events from middle childhood to early adulthood are overrepresented compared to events from other periods. It is, however, unclear whether these memories are also associated with greater recollection. In this online study, we examined whether autobiographical memories from adolescence and early adulthood are recollected more than memories from other lifetime periods. Participants rated personal events that were elicited with cue words on reliving or vividness. Consistent with previous studies, most memories came from the period in which the participants were between 6 and 20 years old. The memories from this period were not relived more or recalled more vividly than memories from other lifetime periods, suggesting that they do not involve more recollection. Recent events had higher levels of reliving and vividness than remote events, and older adults reported a stronger recollective experience than younger adults.

Mental hoop diaries: emotional memories of a college basketball game in rival fans.

The rivalry between the men's basketball teams of Duke University and the University of North Carolina-Chapel Hill (UNC) is one of the most storied traditions in college sports. A subculture of students at each university form social bonds with fellow fans, develop expertise in college basketball rules, team statistics, and individual players, and self-identify as a member of a fan group. The present study capitalized on the high personal investment of these fans and the strong affective tenor of a Duke-UNC basketball game to examine the neural correlates of emotional memory retrieval for a complex sporting event. Male fans watched a competitive, archived game in a social setting. During a subsequent functional magnetic resonance imaging session, participants viewed video clips depicting individual plays of the game that ended with the ball being released toward the basket. For each play, participants recalled whether or not the shot went into the basket. Hemodynamic signal changes time locked to correct memory decisions were analyzed as a function of emotional intensity and valence, according to the fan's perspective. Results showed intensity-modulated retrieval activity in midline cortical structures, sensorimotor cortex, the striatum, and the medial temporal lobe, including the amygdala. Positively valent memories specifically recruited processing in dorsal frontoparietal regions, and additional activity in the insula and medial temporal lobe for positively valent shots recalled with high confidence. This novel paradigm reveals how brain regions implicated in emotion, memory retrieval, visuomotor imagery, and social cognition contribute to the recollection of specific plays in the mind of a sports fan.

The short and long of it: neural correlates of temporal-order memory for autobiographical events.

Previous functional neuroimaging studies of temporal-order memory have investigated memory for laboratory stimuli that are causally unrelated and poor in sensory detail. In contrast, the present functional magnetic resonance imaging (fMRI) study investigated temporal-order memory for autobiographical events that were causally interconnected and rich in sensory detail. Participants took photographs at many campus locations over a period of several hours, and the following day they were scanned while making temporal-order judgments to pairs of photographs from different locations. By manipulating the temporal lag between the two locations in each trial, we compared the neural correlates associated with reconstruction processes, which we hypothesized depended on recollection and contribute mainly to short lags, and distance processes, which we hypothesized to depend on familiarity and contribute mainly to longer lags. Consistent with our hypotheses, parametric fMRI analyses linked shorter lags to activations in regions previously associated with recollection (left prefrontal, parahippocampal, precuneus, and visual cortices), and longer lags with regions previously associated with familiarity (right prefrontal cortex). The hemispheric asymmetry in prefrontal cortex activity fits very well with evidence and theories regarding the contributions of the left versus right prefrontal cortex to memory (recollection vs. familiarity processes) and cognition (systematic vs. heuristic processes). In sum, using a novel photo-paradigm, this study provided the first evidence regarding the neural correlates of temporal-order for autobiographical events.
