In the first essay, I examine the impact of the introduction of exchange traded funds (ETFs) options on the information related trading of index options. Two option pairs, NASDAQ 100 index (NDX) and ETF (QQQ, currently QQQQ ) options, and Standard and Poor's 500 index (SPX) options and S & P Depository Receipts (SPY) options, are studied. I test the hypothesis, based on the theory of Chowdhry and Nanda (1991), and Admati and Pleiderer (1988), that the information component of spreads for index options should decline after ETF options were introduced. The method of George, Kaul and Nimalendran (1991) is used to estimate the adverse selection proportion of log quoted spread and revenue from quoted spread. Primary results show that the adverse selection component of index options declines after the introduction of ETF options, and that the adverse selection component of options on index ETFs is greater than that of options on index, suggesting more informed trading for ETF options. The second essay examines whether the liquidity premium decreases as the costs of transactions decline. Nine liquidity measures are estimated to form liquidity deciles portfolios. I use several benchmark asset pricing models in fixed and rolling 36-month samples to estimate time variation liquidity premia. Surprisingly, the results show that the liquidity premium does not monotonically decline over time, and it increases in the period from 2001 to 2006. This is inconsistent with the implication of liquidity-adjusted capital asset pricing models (L-CAPM). It is likely that the liquidity premium is generated by size and book-to-market factors, rather than the liquidity factor.

Esta pesquisa consiste na realização de um estudo sobre um grupo de terapia ocupacional, na tentativa de se observar um processo grupal no campo da reabilitação, no que diz respeito à articulação entre subjetividade e lugar social de seus integrantes. Refletir sobre a possibilidade do grupo de terapia ocupacional constituir-se em espaço para a construção de novos projetos de vida para os participantes, considerando-se a manifestação de limites - sejam eles de ordem física, psíquica, social ou institucional - e de potencialidades que emergem, é nosso objetivo. A discussão apóia-se em pesquisa realizada com sujeitos portadores de deficiência ou transtorno psíquico na Estação Especial da Lapa, através da constituição de um grupo de Terapia Ocupacional e o acompanhamento de seu processo durante 7 meses. Foram realizadas atividades internas à instituição e também algumas saídas aos espaços sociais. Para a análise do processo grupal, utilizou-se o referencial teórico de E. Pichon-Rivière (embora a condução do grupo respeitasse os procedimentos da Terapia Ocupacional), aliado aos conhecimentos da prática em terapia ocupacional. Pela utilização do referencial pichoniano, considera-se que os aspectos institucionais são constituintes do processo, portanto a leitura grupal é mediada pelas questões do contexto institucional. A partir da reflexão sobre o campo das deficiências e o campo da saúde mental, busca-se discutir a possibilidade de maior diálogo entre essas duas áreas de conhecimento, no sentido de apontar o grupo como dispositivo de investigação e intervenção em reabilitação. A abordagem grupal em terapia ocupacional é pensada sobre sua condição de permitir a manifestação de conteúdos relativos às histórias subjetivas e inter-subjetivas, sua elaboração e a possibilidade de sua re-significação. Pelos conteúdos que se manifestaram e pela análise do processo grupal, considerou-se a efetividade deste dispositivo e a (Continuacao) possibilidade do mesmo oferecer uma abertura, uma ampliação do campo de ação e teorização no trabalho com reabilitação / The present project focus on an occupational therapy group in order to study a group process in the rehabilitation field in terms of the relationship between the participants subjectivity and their social space. It is our aim to consider the possibility of making the occupational therapy group a space to build new life project for the participants, taking into account their limitations - physical, psychic, social and institutional -and their potentialities. This discussion is supported by a seven-month study carried out at Estação Especial da Lapa in an Occupational Therapy group formed by disabled or psychically disturbed people. Activities were developed inside the institution as well as in social environments outside. The group process analysis was based on E. Pichon-Rivières theoretical reference (although the group work followed the Occupational Therapy procedures) combined with the knowledge obtained in the occupational therapy practice. According to the Pichonian reference, the institutional aspects take part in the process, therefore, the group reading includes the institutional context issues. Considering the disability and mental health fields, we discuss the possibility of a more intensive interchange of knowledge between these two areas in order to make the group a device for the rehabilitation investigation and intervention. The Occupational Therapy group approach is analyzed in terms of its condition to promote the manifestation of contents related to subjective and inter-subjective history and in terms of its formation and the its possibility of acquiring a new meaning. Based on the manifested contents and the group process analysis, the effectiveness of this device as well as its prospects to provide new practical and theoretical basis were studied

The discipline of orthopaedic surgery is a fast growing surgical specialty directed at the diagnosis and management of disorders of the musculoskeletal system e.g. acute trauma, fractured or dislocated joints, elective reconstructive surgery as well as related research. The standard of care in orthopaedic surgery treatment reflects the status of its evolution and what is currently available in terms of the knowledge, surgical expertise, orthopaedic implant materials, and equipment. It is the duty of the orthopaedic surgeon to live up to the promise as best he or she can to heal when it is possible to heal and to provide the level of care expected that transcends simple surgical expertise and bio-technological intervention. The informed consent process is an often neglected but vital component of the standard of care which has to satisfy prescribed ethical and legal requirements. This research is focused on how to heighten the awareness of, and to encourage engagement within the orthopaedic surgery fraternity with the informed consent process. If the informed consent is given more recognition within this group, it will benefit the potentially vulnerable orthopaedic patient, protect the orthopaedic surgeon against litigation, and importantly, contribute to the ethical imperatives bound in a doctor-patient relationship. For this research, a vast search of the available local and international literature has been perused and my finding is that the application of Ethics and recognition of the informed consent concept within the medical community in general is gathering momentum and it must be both supported and internalized by those in orthopaedic surgical practice.

Thesis advisor: V. Paul Poteat / Intimate partner violence (IPV) occurs in LGBTQ (lesbian, gay, bisexual, transgender, queer) relationships at rates equal to or even higher than cisgender heterosexual relationships (Walters, Chen, & Breidig, 2013). The health consequences of IPV are well documented (Kwako et al., 2011). Trauma-informed care (TIC) is one service approach receiving increasing support for use with IPV survivors (Warshaw, Lyon, Phillips, & Hooper, 2014). Nevertheless, there is little research exploring the association between TIC and health among LGBTQ IPV survivors. Immobilization is prevalent for IPV survivors for whom fight or flight may increase risk of violence during traumatic situations (van der Kolk, 1989). TIC might be well-positioned to counter these immobilizing effects in effort to facilitate mobilization and better health for IPV survivors. The relationship between TIC and health through mobilizing mechanisms has not yet been tested. This study examined several mobilizing mechanisms as mediating the relationship between TIC and health including: 1) lower social withdrawal; 2) lower shame; 3) greater emotion regulation; and, 4) greater empowerment. Among 227 LGBTQ adults, structural equation modeling analyses tested the relationship between TIC and health, and the mediating effects of lower social withdrawal and shame, and greater emotion regulation and empowerment on the relationship between TIC and health. Results indicated that the direct effects of TIC on mental and physical health were not significant. Indirect effects of TIC on mental and physical health through the set of mobilizing mechanisms were not significant. However, TIC did predict greater empowerment and emotion regulation and lower social withdrawal. Lower social withdrawal and lower shame also predicted better mental health, while lower shame and emotion regulation predicted better physical health. Practitioners need to uncover additional services and resources beyond TIC that could improve health among LGBTQ IPV survivors. Research should continue to examine the potential effects of TIC in addition to how it is applied in the context of evidence-based treatment programs that are adapted for sexual and gender minorities. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

Informed consent is one of the most discussed issues of medical law. This thesis tries to contribute to the discussion through a comparative study between Czech law and Canadian law (the common law part of Canadian law), focusing on the basic components of the subject matter. The thesis is divided into six parts. The first one deals with information disclosure and consent to treatment in the paternalistic model and the participatory model of a doctor-patient relationship. The second part provides an overview of relevant Czech and Canadian legal sources and also of key milestones in the development of informed consent in both countries. The third part of the thesis discusses the concept of informed consent. The fourth part is focused on the disclosure - its content and scope, form and other related aspects. The fifth part of the thesis deals with the consent itself - its elements, the withdrawal of consent and the refusal to give consent. Finally, the sixth part deals with the specifics of minors. With regard to the basic features of informed consent, it can be clearly stated that the compared legal systems are fundamentally the same. Differences can be seen only when analysing the subject matter into very great detail and those differences are usually various technicalities (e.g. determination of...

Apresenta uma intervenção institucional em empresa e, a partir dela, discute as questões suscitadas pela pratica psicossocial no interior das organizações. Utiliza como método uma combinação das táticas dos grupos operativos de pichon-riviere, com o referencial critico de análise institucional de r.Lourau e g.Lapassade. A intervenção consiste em sessões de grupo e posterior re-análise que conduz a discussão dos múltiplos entraves e contradições que atravessam a pratica do psicólogo social e levam, não raro, ao incremento das estruturas coercitivas e totalitárias das instituições. Conclui pela necessidade de uma permanente critica das praticas psicossociais, de modo a promover uma práxis renovada e transformadora do real e de si mesmo / Not informed

Esta tese foi baseada em orientações contraditórias sobre alei-tamento recebidas por uma puérpera, vindas, de um lado, da equipe profissional, e de outro, de uma faxineira presente em uma enfermaria de uma maternidade pública da periferia de São Paulo. Os objetivos foram constatar: quem realiza os cuidados cotidianos do primeiro be-bê de uma mãe jovem, como ela se percebe nesta função, em quem se apoia na execução destes cuidados, com quem se orienta, e quem ela acredita entender de desenvolvimento da criança. Utilizou-se as teorias da evolução e etológico-interacionista, com o conceito de adaptação homem-ambiente como guia. Introduziu-se as questões históricas, do meio social e físico. A metade das avós maternas da população pesquisada nasce-ram no norte/nordeste, regiões predominantemente agrárias, onde há uma tradição de início precoce de constituição de novos núcleos fami-liares. A população entrevistada foi dividida em um grupo que coabita com o pai do bebê e um que não coabita. O primeiro tende a morar em local separado. O segundo tende a coabitar na residência de sua própria mãe. Demonstra-se que as mães jovens, de ambos os grupos, são as reponsáveis pelos cuidados práticos do bebê e que declaram não encontrar dificuldades para desempenhar estas tarefas. As que não coabitam com o pai, mas com a própria mãe, concentram nesta pessoa a origem da ajuda recebida quanto aos cuidados e às orientações, e as percebem como quem mais entende do desenvolvi-viii mento da criança. As que coabitam com o pai do bebê em outra casa, percebem-se mais competentes e se referenciam menos em suas mães quanto às orientações, ampliando o número de pessoas que cumprem esta função, situação em que o pediatra começa a aparecer. A mesma tendência ocorre, neste grupo, em relação a quem elas acreditam ser quem mais entende do desenvolvimento da criança. A esperança é que estas informações sejam úteis para as equi-pes multiprofissionais dos programas públicos de saúde, especialmente os preventivos, como uma contribuição da psicologia para o desenvolvimento cognitivo e emocional dos bebês, através da instrumentalização mais eficaz de seus cuidadores / This Theses was based on different opinions about breastfeed-ing, one from a charwoman, and other from the staff in a Municipal Maternity in the outskirts of São Paulo. The objectives were to know: who takes care of a first infant of a very young mother, her awareness of this situation, who supports her, who advises her and who she be-lieves in about the childs development. Evolutionary and ethological-interactionist theories were used, guided by the concept of human-environment adaptation. Historical, social and physical environment issues were introduced. Half of the maternal grandmothers are from a poor agrarian region were tradionally the constitution of the family starts at a very early age. Two groups of people were interviewed: one who lives with the babys father and one who does not. The former group usually lives on his own. The latter usually lives in the mothers mothers house. We found that the young mothers themselves, in both groups, look after their babies without further difficulties. The mothers who live with their mothers and not the childs father, tend to count on their own mothers to guide and help them with the child care, and look up to them as someone who understands about the development of the child. The ones who live with the childs father are more self confident, refer less to their mothers and count on different people in-cluding the pediatrician to advise them, counting more on their knowledge. x I hope that this information will be useful for multiprofession-al groups that work with public health programs, specially preventive ones

Esta dissertação empreende análise da estrutura SematosÊmica-Signumicular da Língua de Sinais Brasileira (Libras) em termos de cruzamentos entre os seguintes parâmetros: Articulação de cada Mão; Orientação de cada Palma; Orientação de cada Mão; Relação entre Mãos; Movimento de cada Mão; Expressão Facial indicando Sentimentos Positivos e de Sentimentos Negativos. Foi utilizado o software BuscaSigno-2 para empreender a análise do corpus de 10.400 sinais da 2a. edição revista e ampliada do Novo Dicionário enciclopédico ilustrado trilíngue da Língua de Sinais Brasileira (Libras) de Capovilla, Raphael e Mauricio (2012). O objetivo foi caracterizar Libras em busca das combinações mais características entre os SematosEmas dos sinais de Libras. A dissertação apresenta os dados de uma extensa análise piloto que usou BuscaSigno-2 para computar as incidências absoluta e relativa de sinais que contêm os 13 seguintes cruzamentos entre SematosEmas: 1: articulação da mão direita e articulação da mão esquerda (AMD x AME); 2: articulação da mão direita e movimento da mão direita (AMD x MMD); 3: articulação da mão direita e orientação da palma direita (AMD x OPD); 4: articulação da mão esquerda e movimento da mão esquerda (AME x MME); 5: articulação da mão esquerda e orientação da palma esquerda (AME x OPE); 6: articulação da mão direita, orientação da mão direita, orientação da palma direita (AMD x OMD x OPD); 7: articulação da mão esquerda, orientação da mão esquerda, orientação da palma esquerda (AME x OME x OPE); 8: articulação da mão direita, orientação da palma direita, e movimento da mão direita (AMD x OPD x MMD); 9: articulação da mão direita, articulação da mão esquerda, relação entre mãos (AMD x AME x RM); 10: movimento da mão direita, sentimentos sensações positivas (MMD x SSP); 11: movimento da mão direita, sentimentos sensações negativas (MMD x SSN); 12: articulação da mão direita, movimento da mão direita, sentimentos sensações positivas (AMD x MMD x SSP); 13: articulação da mão direita, movimento da mão direita, sentimentos sensações negativas (AMD x MMD x SSN). Em busca de caracterizar as combinações mais típicas entre os SematosEmas em Libras, foram analisados 122.163 cruzamentos em busca dos sinais que os contivessem. Foram computados os sinais em cada um desses 122.163 cruzamentos. Dos 122.163 cruzamentos analisados, foram identificados 21.328 cruzamentos válidos (i.e., com incidência superior a zero). Destes, foram identificados 369 cruzamentos canônicos (i.e., com incidência maior que 50% da incidência total naquele tipo de cruzamento). Esses 369 cruzamentos canônicos foram, então, ordenados por incidência decrescente, de modo a caracterizar Libras em seu \"DNA\" com vistas a permitir estudos ulteriores de Linguística Comparada entre Libras e outras línguas de sinais. Esta dissertação apresenta essas combinações mais típicas, refinando essas análises e apreciando os achados à luz do Modelo de Processamento de Informação da Psicologia Cognitiva, e do Novo Paradigma Neuropsicolinguístico de Linguagem Oral, Escrita e de Sinais de Capovilla (2011, 2012, 2013). Esta dissertação também torna possível descobrir o grau de utilidade de cada um dos SematosEmas- SignumÍculos de Libras para empreender a recuperação lexical desses sinais de Libras por parte de surdos brasileiros / The present thesis analyzes the phonological (SematosEmic) structure of Brazilian Sign Language (Libras) in terms of crossings among the following parameters: handshape; palm orientation; hand orientation; relationship between hands; hand movement; and facial expression indicating positive and negative feelings. SignTracking-2 software (Duduchi & Capovilla, 2006) was used to undertake the analysis of the corpus of 10,400 signals of the second edition of the New Libras dictionary (Capovilla, Raphael, & Mauricio, 2012). The objective was to characterize Libras in search of combinations among the most typical SematosEmes. This thesis presents data from an extensive pilot analysis that used SignTracking-2 to calculate the absolute and relative incidences of signs containing the following 13 intersections among SematosEmes: 1: right handshape and left handshape (AMD x AME); 2: right handshape and right hand movement (AMD x MMD); 3: right handshape and right palm orientation (AMD x OPD); 4: left handshape and left hand movement (AME x MME); 5: left handshape and left palm orientation (AME x OPE); 6: right handshape and right hand orientation and right palm orientation (AMD x OMD x OPD); 7: left handshape and left hand orientation and left palm orientation (AME x OME x OPE); 8: right handshape and right palm orientation and right hand movement (AMD x OPD x MMD); 9: right handshape and left handshape and relationship between hands (AMD x AME x RM); 10: right hand movement and positive facial expression (MMD x SSP); 11: right hand movement and negative facial expression (MMD x SSN); 12: right handshape and right hand movement and positive facial expression (AMD x MMD x SSP); 13: right handshape and right hand movement and negative facial expression (AMD x MMD x SSN). In order to discover what are the most typical combinations among Libras SematosEmes, 122.163 SematosEme combinations were analyzed and the incidence of signs containing those combinations in the sign corpus of the dictionary was computed. Using the software BuscaSigno-2, the incidence of signs pertaing to each of the 122.163 combinations was computed. Of the 122.163 combinations analyzed, the software identified 21.328 valid combinations with incidence greater than zero. After that, the software computed the sign incidence at each of the 21.328 valid combinations, and calculated the mean sign incidence. Based on that, the software identified the 369 canonical combinations, in which the sign incidence was greater than the average sign incidence in all combinations. These 369 canonical combinations were then ordered by decreasing incidence, in order to characterize Libras in its \"DNA\". Such a characterization is useful for further studies in Sign Language Comparative Linguistics, in which Libras is to be compated to other sign languages. The present thesis presents the most typical combinations among SematosEmes that characterize Libras. The findings are discussed in the light of the Information Processing Model of Cognitive Psychology and the New Paradigm Neuropsycholinguistic of Oral Language, Writing and Signal from Capovilla (2011, 2012, 2013). The present thesis paves the way to further studies on the relationships between sign structure and cognitive sign processing, such as memory sign retrieval Libras by the Brazilian deaf

Relata 11 atendimentos de pacientes psicossomaticos do ambulatorio da fm de sao jose rio preto-sp. Discute o significado dos relatos para a configuracao de uma proposta de investigacao psicanalitica dos fenomenos psicossomaticos. A partir da demanda e da necessidade de promover adequacao entre a forma de escuta preconizada pela psicanalise, e as condicoes proprias desse atendimento institucional, inicia uma pratica clinica que procura caracterizar, no que ela tem de proprio e de heuristico. Localiza o problema implicito a psicossomatica, a interacao corpo-mente, interseccao de diversos saberes e campo fronteirico entre a psicanalise e a medicina assinalando contradicoes e dificuldades. Apresenta um relato da historia da medicina, dos primordios ate o seculo xix, quando a histeria e seus enigmas tornam-se ponto de partida para um novo saber. Descreve o surgimento da psicanalise, apresentando os principais pontos da teoria psicanalitica relevantes para a compreensao da formacao dos sintomas e da somatizacao. Propoe uma divisao entre a medicina psicossomatica e a psicossomatica psicanalitica. Enfim, apresenta 3 pontos para o balizamento da proposta: a consideracao do sintoma psicossomatico como um hieroglifo, o modelo da faixa de moebius como representacao apropriada para a interacao corpo-mente, e o ato psicanalitico como definidor da natureza da intervencao psicossomatica / The present work has emerged from the questions arisen at the clinicai treatment of patients who look for the Service of the Medicai College of São José do Rio Preto, São Paulo, Brazil, in order to get the relief to their psychosomatic sufferings. From their demand and the need to promote an adequacy between the way of \"listening\" recommended by the Psychoanalysis and the own conditions of the institutionai service, a clinicai service, which we try to characterize here with its own and heuristic aspects, has begun. We have started by the location of the problem implicit in Psychosomatics, the mind-body interaction, in the intersection of several knowledges and borderline field between the Psychoanaiysis and Medicine. We have marked some of the contradictions present in this field and the difficulties of their characterization. Then we have proceeded to a report of the History of Medicine since its origins concerning healing through the 19th century when, with the adoption of the Cartesian dichotomy between mind-body and new medicai paradigms, the Hysteria and its enigmas became the starting point for a new knowledge. We described the appearence of Psychoanaiysis showing the main points of the psychoanalytic theory relevant to the understanding of the formation of symptoms and somatization. We propposed a division into two branches derived from the impact of the Psychoanaiysis on the heaiing techniques: the Psychosomatic Medicine and the Psychoanaiytic Psychosomatics, having collected their respective contributions. Thus we presented this paper which should be considered the minute of the foundation ofPsychosomatics. We propposed that in Georg Groddeck\'s work one may find the basis of a psychoanaiytic practice towards these patients. We have condensed and worked his best book, The Book of the It. Next, we presented the parameters of a Psychosomatic Practice inspired by this perspective. We have reporteded eleven cases of psychosomatic patients seen at the Service, and we have discussed what they mean when working out a proposal of a psychoanalytic investigation of the psychosomatic phenomena. Finally we presented three parameters for the delimitation of this proposal: the consideration of the psychosomatic symptom as a hieroglyph, the model of the Moebius\' Band as a proper representation of the mind-body interaction, and the psychoanalytic act as a nature-defining act of the psychosomatic intervention

Esta pesquisa analisa o estatuto da letra nos noves primeiros seminários de Jacques Lacan. Parte-se de uma questão sobre a gênese do conceito na obra, ao se analisar o texto Linstance de la lettre dans linconscient ou la raison depuis Freud e aparições de ideias relativas a leitura e escrita do inconsciente nos quatro primeiros seminários. A noção de transliteração é tomada aqui como uma operação simbólica da letra. Num segundo momento, a análise se voltará a problemática do traço unário no seminário IX e uma possível separação da leitura e escrita, quando o psicanalista fala de uma gênese do escrito a partir da leitura do rastro (trace) e da escrita do significante ao tratar do traço (trait) unário / This research analyzes the statute of the letter in the first nine seminars of Jacques Lacan. It begins with a question about the genesis of the concept in the work, when analyzing the text L\'instance de la lettre dans l\'inconscient or la raison depuis Freud and apparitions of ideas regarding reading and writing of the unconscious in the first four seminars. The notion of transliteration is taken here as a symbolic operation of the letter. Secondly, the analysis will turn to the problematic of the unary trait in seminary IX and a possible separation of reading and writing, when the psychoanalyst speaks of a genesis of the writing from the reading of the trace and the writing of the signifier when talking about the trait unary
