No. of bitstreams: 1 DIS_CAROLINA_VIECILI_AZAMBUJA_PARCIAL.pdf: 177646 bytes, checksum: deacc5840ab81b49289873f73fda38cd (MD5) Previous issue date: 2017-01-19 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Depression is a very common medical condition with high prevalence among the population. Among the specifiers of the disorder, one of the most prevalent conditions during pregnancy or puerperium is maternal postpartum depression (PPD). Gestation and the postpartum period are considered risky moments for the development or increase of psychiatric disorders in women, and in particular, PPD. The present dissertation is comprised of two empirical studies; The first addresses the impact of maternal postpartum depression on mother-baby interaction considering the dimensions of the mother, baby, and the duo. The study counted on the participation of 27 pairs, of these, nine with symptoms of depression and 18 without the presence of the disorder, recruited in five different cities of Rio Grande do Sul. The women answered the questionnaire of general questions, which was developed especially for this research, EPDS (cutoff ?11 points), BDI, BAI, SCID, WASI, filming and GRS. Descriptive analyzes, correlation analyzes, MANOVAs and MANCOVAs with covariations were performed. Among the main results obtained, it was found that the prevalence of PPD was 33%, which is higher than the literature indicates. Schooling is significantly and positively related to better maternal indexes of interaction. Overall, mothers had moderate rates of interaction, while infants had low and intermediate rates and low rates for double, regardless of the presence of PPD. On the other hand, in all dimensions of the interaction scale, the indices of women with PPD were lower than the results of women without PPD, demonstrating implications in the interaction. In study two, the same one approaches the processing of facial expressions of adults and of babies. The study had the participation of 22 women, 19 of whom answered the task of adult faces and 22 a of babies, of these 08 depressed and 14 controls. Participants were recruited at the same sites of study 1 and same instruments applied - for this study filming was not analyzed as well as the interaction scale, but the task of face recognition was included. For the analysis of the data, the SPSS program was used and ANOVAs, MANCOVAs, correlations and descriptive analyzes were performed. Among the main results, women with PPD presented lower accuracy for the facial expressions of infants and adults and classified the faces with less intensity as the exposure time increased, when compared to the control group. The findings of the study point to the deficits in relation to the recognition of facial expressions in women with PPD, which may lead to a decrease in the quality of the mother-baby relationship, since adequate responses to the baby's demands are hampered by the distortions in the recognition of the emotion expressed by the child. Unsuccessful interactions can lead to problems in the baby's development. The findings of both studies point to the need for more research in the area which seeks to contribute to prevention and intervention / treatment of mediators and moderators of the quality of the mother-infant relationship in cases of PPD. / A depress?o ? uma condi??o m?dica muito comum e com alta preval?ncia entre a popula??o. Dentre os especificadores do transtorno, um dos quadros com maior incid?ncia durante a gesta??o ou puerp?rio ? a depress?o p?s-parto materna (DPP). A gesta??o e o per?odo p?sparto s?o considerados momentos de risco para o desenvolvimento ou aumento de transtornos psiqui?tricos em mulheres e, em especial, a DPP. A presente disserta??o ? composta por dois estudos emp?ricos; o primeiro aborda o impacto da depress?o p?s-parto materna na intera??o m?e-beb?, levando em considera??o as dimens?es da m?e, do beb? e da dupla. O Estudo I contou com a participa??o de 27 duplas e, destas, nove com sintomas de depress?o e 18 sem a presen?a do transtorno, recrutadas em cinco diferentes cidades do Rio Grande do Sul. As mulheres responderam ao question?rio de perguntas gerais, que foi desenvolvido especialmente para esta pesquisa: EPDS (ponto de corte ?11 pontos), BDI, BAI, SCID, WASI, filmagem e GRS. Foram realizadas an?lises descritivas, an?lises de correla??o, MANOVAs e MANCOVAs, com covaria??es. Dentre os principais resultados obtidos, constatou-se que a preval?ncia de DPP encontrada foi de 33%, ?ndice maior do que aponta a literatura. Escolaridade est? relacionada significativa e positivamente a melhores ?ndices maternos de intera??o. Em todas as dimens?es da escala de intera??o, os ?ndices de mulheres com DPP foram inferiores aos resultados das mulheres sem DPP. O Estudo II aborda o processamento de express?es faciais de adultos e de beb?s. A amostra foi composta por parte das m?es do Estudo I. Participaram 22 mulheres, sendo que 19 responderam a tarefa de faces adultas e 22 a de beb?s; destas, 08 deprimidas e 14 controles. Para este estudo, al?m dos instrumentos de dados demogr?ficos e avalia??o materna, foi inclu?da a tarefa de reconhecimento de faces. Para as an?lises dos dados, o programa SPSS foi utilizado e tamb?m ANOVAs, MANCOVAs, correla??es e an?lises descritivas foram realizadas. Dentre os principais resultados, mulheres com DPP apresentaram menor acur?cia para as express?es faciais de beb?s e adultos e classificaram as faces com menos intensidade conforme o tempo de exposi??o aumentava, se comparadas ao grupo controle. Os achados do estudo apontam para os d?ficits em rela??o ao reconhecimento de express?es faciais em mulheres com DPP, o que pode ocasionar na diminui??o quanto ? qualidade da rela??o m?e-beb?, visto que as respostas adequadas ?s demandas do beb? encontram-se prejudicadas pelas distor??es no reconhecimento da emo??o expressa pela crian?a. Intera??es malsucedidas podem acarretar problemas no desenvolvimento do beb?. Os achados de ambos os estudos apontam para a necessidade de mais pesquisas na ?rea, que busquem contribuir para a preven??o e a interven??o/tratamento do mediadores e moderadores da qualidade da rela??o m?e-beb? em casos de DPP.

The research was inspired by the necessity of given voice to ancestors which live inside my body ? especially my maternal grandmother, whose past had been marked by the overwhelming trauma of World War II. Considering the emptiness of a missing past, I formulate the following question: How is it possible to take on pre-birth memories? To do so, I deal with multiple verbal tenses and narrative voices in the fictional part in order to demonstrate gaps or to heal the wounds by filling in them imaginative spaces. Due to its synaesthetic feature, the critical essay gathers historical documents, photographs, films, diaries? fragments, family texts, as well as conversations with patients which inspired the development of the novel. Furthermore, I carried out a thorough affective study on the vacuum that may last between generations with the purpose of stablishing not only a bond, but also a contact. / Esta disserta??o ? constru?da em dois volumes: o romance A casa das bolsas e o ensaio cr?ticote?rico sobre a cria??o art?stica, Forros (In)Feridos. O trabalho foi disparado pela necessidade de fazer falar os ancestrais sucumbidos dentro do meu corpo ? especialmente a minha av? materna, cuja hist?ria fora avassalada pelo trauma da Segunda Guerra Mundial. Diante do vazio de um passado esburacado, formulo a pergunta ? como ? poss?vel efetuar uma apropria??o de mem?rias que s?o anteriores ao nosso nascimento? Lan?o m?o de m?ltiplos tempos verbais e vozes narrativas na parte ficcional para escancarar as fendas ou para suturar as feridas com brecha imaginativa. O ensaio cr?tico ? sinest?sico por reunir documentos hist?ricos, fotografias, filmes, trechos de di?rios, textos de familiares e conversas com pacientes que impulsionaram a cria??o do romance. Realizei um mergulho afetivo no v?cuo que pode subsistir entre as gera??es, almejando efetuar la?o e promover um contato.

This is a qualitative case study which is based on the method of analysis of the policy cycle (BOWE, BALL, GOLD, 1992; Ball, 1994) to understand the network of policies and knowledge surrounding the internationalization of higher education and its weight in the evaluation of graduate programs conducted by CAPES. Through documentary analysis, questionnaires, and semi-structured interviews it was possible to understand how the administrators and professors of a program evaluated by CAPES at four, and another at five, deal with internationalization in the context of praxis at the same institution. The Bardin Content Analysis (2010) and the Statistical Package for Social Sciences (SPSS) were used to interpret the qualitative and quantitative data. The results show weaknesses in the dynamics of internationalization experienced in everyday programs by their administrators and professors, compromising their performance. Despite the existence of international activities, the process is incipient and isolated in each program. There is a lack of institutional policies with financial support and internationalization strategies built with the demands of the current National Plan for Graduate Studies in mind. Since internationalization is an important criterion in CAPES evaluations, it needs to be prioritized in the internal policies of graduate programs, contributing to the expansion of international academic production and strengthening partnerships. / Esta pesquisa investiga como a proposta de internacionaliza????o do Plano Nacional de P??s-Gradua????o (2011-2020) ?? traduzida no contexto da pr??tica de dois programas Stricto Sensu de uma institui????o de educa????o superior privada da Regi??o Centro-Oeste. Trata-se de um estudo de caso qualitativo que se inspira no m??todo de an??lise do ciclo de pol??ticas (BOWE; BALL; GOLD,1992; BALL,1994) para compreender as redes de pol??ticas e conhecimentos que cercam a internacionaliza????o da educa????o superior e o seu peso na avalia????o de programas de p??s-gradua????o realizada pela CAPES. Por meio da an??lise documental, question??rios e entrevistas semiestruturadas foi poss??vel compreender como gestores e docentes de um programa com nota quatro e outro com nota cinco lidam com a internacionaliza????o no contexto da pr??tica da mesma institui????o. A An??lise de Conte??do de Bardin (2010) e o Statistical Package for the Social Sciences(SPSS) foram utilizados para tratar os dados qualitativos e quantitativos. Os resultados revelam fragilidades na din??mica de internacionaliza????o vivenciada no cotidiano dos programas por seus gestores e docentes, o que compromete um melhor desempenho. Apesar da exist??ncia de a????es de internacionaliza????o, o processo ocorre de modo incipiente e isolado em cada programa. Falta uma pol??tica institucional com apoio financeiro e estrat??gias de internacionaliza????o articuladas com as demandas do atual Plano Nacional de P??s-Gradua????o. Por ser um crit??rio importante na avalia????o da CAPES, a internacionaliza????o dos programas precisa ser priorizada na pol??tica interna de p??s-gradua????o da universidade, contribuindo para a amplia????o da produ????o acad??mica internacional e fortalecendo as parcerias.

Dissociation is defined as changes in the integration of perception and consciousness, provoking states of derealization and depersonalization. It is discussed on literature the role of traumatic stressors, especially if in childhood in the expression of dissociation reactions. Theoretical models propose different levels of importance of the traumatic, and those who argue that the event is a triggering factor or at least a mediator are the ones most empirical support. This dissertation present empirical findings from a clinical assessment in a population of trauma victims. With this, it was aimed to determine the role of different factors as predictors of dissociative symptoms. The empirical study conducted a logistic regression with 47 patients from an outpatient trauma seeking to develop a model considering the main predictors. Results indicated significant predictors, post- traumatic, depressive and anxiety symptoms, as well as trauma and child maltreatment. The role of these findings in different theoretical models on the etiology of dissociative symptoms are discussed. Furthermore, a systematic review aimed to evaluate the effect of different interventions focused on dissociative symptoms in the treatment of Post Traumatic Stress Disorder ( PTSD ). A total of 17 empirical articles were analyzed. All studies point out to a concomitant decrease of dissociative and posttraumatic symptoms, but few studies have directly discuss psychological techniques for solving dissociative symptoms. Both studies point to the association between symptomatologies and suggests that future studies of assessment and treatment of PTSD based on a theoretical model must considers this association. / O presente trabalho visa contribuir com dados sobre o fen?meno dissociativo em popula??o v?tima de trauma. Rea??es de dissocia??o envolvem altera??o na integra??o da percep??o e da consci?ncia, causando um estado de desrealiza??o e despersonaliza??o no indiv?duo. ? discutido na literatura sobre o papel de um evento estressor traum?tico, principalmente se ocorrido na inf?ncia na express?o de rea??es de dissocia??o. Modelos te?ricos prop?em diferentes n?veis de import?ncia do evento traum?tico, sendo que os que postulam que o evento ? um fator desencadeante ou ao menos um mediador s?o os que t?m maior embasamento emp?rico. A presente disserta??o traz achados emp?ricos a partir de uma avalia??o cl?nica em uma popula??o v?tima de traumas. Com isto, objetivou-se verificar o papel de diferentes fatores como preditores para os sintomas dissociativos. O estudo emp?rico realizou uma regress?o log?stica com 47 pacientes de um ambulat?rio de trauma buscando desenvolver uma modelo considerando os principais preditores. Resultados apontaram para preditores significantes, a sintomatologia p?s-traum?tica, depressiva e ansiosa, bem como o traumas e maus tratos na inf?ncia. O papel destes achados nos diferentes moddelos te?ricos sobre a etiologia dos sintomas dissociativos s?o discutiddos. Al?m disso, uma revis?o sistem?tica buscou avaliar o efeito de diferentes interven??es enfocadas nos sintomas dissociativos no tratamento de Transtorno de Estresse P?sTraum?tico (TEPT). Um total de 17 artigos emp?ricos foram analisados. Todos os estudos encontrados apontam para uma diminui??o concomitante de sintomatologia dissociativa e p?s-taum?tica, por?m poucos estudos discutem diretamente t?cnicas psicol?gicas para a resolu??o os sintomas dissociativos. Ambos os estudos apontam para a associa??o entre as sintomatologias,e prop?e que futuros estudos de avalia??o e tratamento do TEPT baseiem-se em um modelo te?rico que considere esta associa??o.

Postpartum depression is a specific manifestation of the disorder, affecting women and men. However, few studies address the issue of paternal postpartum depression. In this context, the present study aimed to investigate the effect of paternal postpartum depression on father-infant interaction, and the potential mediators effects (face processing, marital conflict and attention). To this end, two studies, one theoretical and one empirical. The theoretical study comprises a systematic review of the prevalence of postpartum depression in fathers and the impact on child development. Few studies related to the father-infant were found prevalence rates of paternal postpartum depression ranged between 1.2 % and 25.5 %. The empirical study, in turn, examined the effect of paternal postpartum depression on father- child interaction For this quantitative research design with two was performed. A total of 61 dyads father-infant (17 fathers with postpartum depression and 44 controls). Results confirmed the effect of postpartum depression on father-infant interaction. Face processing was confirmed as a mediator. / A depress?o ? uma condi??o m?dica geral com preval?ncia variando entre 4% e 10% da popula??o mundial.

Nesse contexto, o objetivo do estudo foi verificar o efeito da depress?o p?s-parto paterna na intera??o pai-beb?, investigando potenciais mediadores (processamento de faces, conflito conjugal e aten??o). Para isso, foram realizados dois estudos, um te?rico e outro emp?rico. O estudo te?rico realiza uma revis?o sistem?tica sobre a preval?ncia da depress?o p?s-parto nos pais e o impacto para o desenvolvimento infantil. Foram encontrados poucos estudos que inclu?am os fatores investigados, especialmente para as vari?veis intera??o pai-beb? e as implica??es da DPP-P no desenvolvimento infantil. As taxas de preval?ncia sobre a DPP-P variaram entre 1,2% e 25,5%. O estudo emp?rico, por sua vez, examinou o efeito da depress?o p?s-parto paterna na intera??o pai-beb?. Para isso foi realizada uma pesquisa quantitativa com delineamento transversal entre um grupo cl?nico e outro controle. Foram investigadas 61 d?ades pai-beb?, sendo 17 pais com depress?o p?s-parto e 44 controles. Os resultados confirmaram o efeito da depress?o p?s-parto na intera??o pai-beb?.

Thus, the cut research out of aims at identifying the Brazilian Civil Procedure and the Constitution of the Federative Republic of Brazil of the 1988 should establish a dialogue necessary not only in the theoretical field, but also in practice, because the search for a pattern of Civil Procedure has meet the demands of current social. In this sense, shows the characteristics of Postmodernity, which are responsible for defining the panorama that establishes the main analysis of dialogue between the Brazilian Civil Procedure and the Constitution of the Federative Republic of Brazil of the 1988. Moreover, analyzes the primary features of the Constitution of the Federative Republic of Brazil of the 1988 to the Brazilian legal system, as well as its relationship with the national Civil Procedure, considering as a link between the two institutes of the Constitutional Guarantees of the Jurisdiction and of the Process. Also, discusses the trend of the Brazilian Civil Procedure in the Postmodernity, explaining not only the behavior of the Jurisdiction Postmodern, but the species of conflicts of interests are available in the post-modern. Moreover, it is clear that the necessary dialogue between the Brazilian Civil Procedure and the Constitution of the Federative Republic of Brazil of the 1988 now requires an analysis of the legislative civil procedural content in order to determine whether the legislative contemporary production respects the constitutional procedural commandments. Thus, there is, in the end, that the paradigm of the Brazilian Civil Procedure Postmodernity is that it promotes the realization of Constitutional Guarantees of the Jurisdiction and the Procedure, particularly in the practical performance of procedural agents and their assistants, with the objective to resolve conflicts of interest effectively, timely and appropriate. / A pesquisa cient?fica sobre o di?logo entre o Processo Civil Brasileiro e a Constitui??o da Rep?blica Federativa do Brasil de 1988 no contexto temporal da P?s-Modernidade se mostra de import?ncia ?nica porque, na atualidade, fala-se sobre um paradigma de Processo Civil Brasileiro o qual tenha como objetivo a solu??o dos conflitos de modo efetivo, tempestivo e adequado. Assim, o recorte da investiga??o objetiva evidenciar que o Processo Civil Brasileiro e a Constitui??o da Rep?blica Federativa do Brasil de 1988 devem estabelecer um di?logo necess?rio n?o s? no campo te?rico, mas tamb?m na pr?tica, uma vez que a busca por um padr?o de Processo Civil tem de atender ?s exig?ncias sociais atuais. Nesse sentido, evidenciam-se as caracter?sticas da P?s-Modernidade as quais s?o respons?veis por delimitar o panorama em que se estabelece a an?lise principal de di?logo entre o Processo Civil Brasileiro e a Constitui??o da Rep?blica Federativa do Brasil de 1988. Ademais, analisam-se os tra?os primordiais da Constitui??o da Rep?blica Federativa do Brasil de 1988 para o ordenamento jur?dico brasileiro, bem como a sua rela??o com o Processo Civil nacional, considerando-se como elo de liga??o entre os dois institutos as Garantias Constitucionais da Jurisdi??o e do Processo. Tamb?m, aborda-se a tend?ncia do Processo Civil Brasileiro da P?s- Modernidade, esclarecendo-se n?o s? o comportamento da Jurisdi??o P?s- Moderna, mas ainda as esp?cies de conflitos de interesses dispon?veis no cen?rio p?s-moderno. Al?m do mais, percebe-se que o di?logo necess?rio entre o Processo Civil Brasileiro e a Constitui??o da Rep?blica Federativa do Brasil de 1988 passa a exigir uma an?lise do conte?do legislativo processual civil a fim de se verificar se a produ??o legislativa contempor?nea respeita os mandamentos constitucionais processuais. Dessa forma, nota-se, ao final, que o paradigma de Processo Civil Brasileiro da P?s-Modernidade consiste naquele que promove a realiza??o das Garantias Constitucionais da Jurisdi??o e do Processo, sobretudo na atua??o pr?tica dos agentes processuais e seus auxiliares, com o objetivo de solucionar os conflitos de interesse de modo efetivo, tempestivo e adequado.

The cadavers were examined at the scene and at the morgue. Two types of substrates were found: found accidentally and intentionally exposed to the activity of ants. Data collection for the bodies lasted a year, in Rio de Janeiro and Amazonas. Data collection for carcasses was held in July, followed by two years in an army barracks, in Rio de Janeiro. The specimens were collected with tweezers and transported to the laboratory immersed in 70% ethanol. We used three domestic pig - Sus scrofa, dead at the scene by shooting projectile firearm and exposed areas with nests inside a modified Shannon trap, a distance of 50 meters from each other. Four pitfalls were arranged around the traps. Photographs were made and only one or two specimens that caused artifacts were collected, relating them with injuries. The specimens were conducted for Myrmecology Laboratory of the Federal Rural University of Rio de Janeiro for identification. During the research , we analyzed eight cases of human cadavers, in which were collected : a) Myrmicinae subfamily , tribe Solenopsidini possibly genus Solenopsis spp b ) Camponotus sp.1 c ) Camponotus sp.2 d ) Camponotus rufipes ; e) Pheidole sp. 1 f ) Ectatomma sp.1 g ) Cephalotes atratus h) Crematogaster sp.1 i) small ants unidentified. However , only the first taxon was found associated with the corpses of the IML. Associated with animal carcasses were found : a) Solenopsis sp.1 b ) Pheidole sp.1 c ) Brachymyrmex sp.1 d ) Wasmannia sp.1 e) Ectatomma lugens . The latter being associated with animal carcass found accidentally. Among the collected species, Ectatomma sp.1 Brachymyrmex sp.1 and Wasmannia sp.1 causing artifacts were not observed. The lesions encountered can be described as serpentine punctuated by presenting color ranging from yellow to dark brown. They had removing skin surface such as scratches, in some cases, removal of the evolved to underlying tissues. In some cases, the detachment of the epidermis formed a clump of skin similar to those observed in cadavers in more advanced stage of decomposition. The jaws of the ants produce lesions in the superficial vessels causing bleeding postmortem. We also observed similar chemical injuries to injuries intra vitam produced by burning acid and / or smoking. Lesions caused by Solenopsis sp. was possible to trace the tracks of foraging evidenced by formic acid , as well as the accumulation of dirt, indicating the attempt of ants close these post-mortem lesions. It was found that ants can lead to skeletonization of small carcasses. The domestic pig carcasses showed artifacts similar to those found in bodies, at least until they reach the beginning of the initial stage of deterioration, when the activity of the flies hampered his observation. / Este trabalho foi realizado em cad?veres humanos e em carca?as animais, com o objetivo de descrever as les?es e avaliar a evolu??o desses artefatos durante o desenvolvimento do processo de decomposi??o. Os cad?veres humanos foram examinados na cena do crime e no necrot?rio. Dois tipos de carca?as foram avaliadas: encontradas acidentalmente e intencionalmente expostas ? atividade de formigas. A coleta de dados relativa aos corpos durou um ano, no Rio de Janeiro e no Amazonas e a relativa ?s carca?as foi realizada em julho, por dois anos seguidos, no Rio de Janeiro. Os esp?cimes foram coletados com pin?as e transportados ao laborat?rio fixados em etanol 70%. Foram utilizados tr?s porcos dom?sticos - Sus scrofa, mortos no local, atrav?s de disparo de proj?til de arma de fogo e expostos em ?reas com formigueiros dentro de uma armadilha tipo Shannon modificada, a dist?ncia de 50 metros uma das outras. Quatro armadilhas de solo foram dispostas entorno das armadilha Shannon. Fotografias foram confeccionadas e apenas um ou dois exemplares que causaram os artefatos foram coletados, relacionando-os com as les?es. Os exemplares foram conduzidos para o Laborat?rio de Mirmecologia da Universidade Federal Rural do Rio de Janeiro para identifica??o taxon?mica. Durante a pesquisa, foram analisados oito casos de cad?veres humanos, nos quais foram observados: a) Subfam?lia Myrmicinae, Tribo Solenopsidini, g?nero Solenopsis spp; b) Camponotus sp.1; c) Camponotus sp.2; d) Camponotus rufipes; e) Pheidole sp. 1; f) Ectatomma sp.1; g) Cephalotes atratus; h) Crematogaster sp.1; i) formigas pequenas n?o identificadas. Por?m, apenas o primeiro t?xon foi encontrado associado aos cad?veres do IML. Associados ?s carca?as animais foram encontrados: a) Solenopsis sp.1; b) Pheidole sp.1; c) Brachymyrmex sp.1; d) Wasmannia sp.1; e) Ectatomma lugens; sendo esta ?ltima associada ? carca?a animal encontrada acidentalmente. Dentre todas as esp?cies coletadas, Ectatomma sp.1, Brachymyrmex sp.1 e Wasmannia sp.1 n?o foram observadas causando artefatos. As les?es encontradas podem ser descritas como serpentiformes, pontuadas, apresentando colora??o que variava do amarelo at? o marrom escuro. Elas apresentavam remo??o de pele superficial como arranh?es que, em alguns casos, evolu?ram at? a remo??o dos tecidos subjacentes. Em alguns casos, o destacamento da epiderme formou um amontoado de pele similar ?queles observados em cad?veres em est?gio de decomposi??o mais avan?ados. As mand?bulas das formigas produziram les?es nos vasos superficiais causando sangramento p?s-morte. Tamb?m foram observadas les?es qu?micas similares a les?es intra vitam produzidas por queimadura de ?cido e/ou cigarro. Nas les?es provocadas por Solenopsis sp. foi poss?vel tra?ar as trilhas de forrageamento evidenciadas pelo ?cido f?rmico, bem como pelo ac?mulo de sujeira, indicando a tentativa das formigas fecharem estas les?es p?s-morte. Foi verificado que as formigas podem levar a esqueletiza??o de carca?as de pequeno porte. As carca?as de porco dom?stico apresentaram artefatos similares ?queles encontrados em corpos humanos, pelo menos at? alcan?arem o in?cio do est?gio de deteriora??o inicial, quando a atividade dos d?pteros dificultou sua observa??o.

The Research on the Investment Strategy of International Financial Assets - Base on the International Asset Pricing Model

Wu, Hsiu-Kuan 15 August 2012 (has links)
This study uses cluster analysis as the methodology to explore policy of the asset allocation as well as the selection of equities under the multiple-factor asset pricing models. Based on the data of financial market recorded on Bloomberg from 2000/1/4 to 2012/2/10, the conclusions of this study are summarized as following: First at all, under the significance level of 5%, P/S ratio should be included in the multiple-factor asset pricing model. Nonetheless, the significance of proxy agent of foreign exchange volatility in terms of 11-day moving average of USD/JPY foreign exchange spot rate, as well as the interest spread in terms of yields on 10-year US government bond subtracting 3-month US treasury bill cannot pass the required significance level. Second, the rates of stock return as Qualcomm, Intel and Texas instruments in the industry supply chain of technology products, will be positively related to interest spread, with the variable of ¡§Foreign_Volitility¡¨ negatively related to those rates of return as well as sales growth momentum positively related to those. As far as those rates of stock return 3C brand companies such as Apple, Microsoft, Dell and IBM, the interpreting capability of variable of ¡§Foreign_Volitility¡¨ under the assumptions of market structure in this study, will be mixed, with the interest spread positively related to those returns and P/S ratio generating mixed outcomes. As far as those equities such as GE, Procter & Gamble, Home Depot, Tiffany, AIG, NIKE, Exxon Mobile Corp, the interpreting capability of variable of ¡§Foreign_Volitility¡¨ under the assumptions of market structure in this study, will be negatively related to stock return except for Exxon Mobile Corp, with the interest spread generating mixed outcomes and P/S ratio positively related to those returns.

Att återuppstå i rådande upplevelseekonomi : En studie av Grand Hotel i Gävle

Söderström, Robert, Car, Emma January 2014 (has links)
Syfte: Denna studie syftar till att öka förståelsen för hur ett nytt företag kan påbörja sin marknadsföring i sociala medier samt bidra till innovationsspridning. Sociala medier är något som på senare tid har växt kraftigt och potentialen för företags marknadsföring är stora. Metod: Vår studie utgår från en abduktiv kvalitativ metod. Empiriska data har samlats in genom ostrukturerade intervjuer som sedan har analyserats. Resultat och slutsats: Hotellindustrin i Gävle upplever idag en hård konkurrens. Flera hotell konkurrerar om samma antal kunder som tidigare. Detta ställer stora krav på att hotellen skapar en unik upplevelse som får kunder att återkomma. Genom att Elite Grand Hotel är nystartat i Gävle är det svårt i dagsläget att se ett konkret resultat av deras ansträngningar att differentiera sig. Förslag till fortsatt forskning: Då Elite Grand Hotel är nystartat finns det stora möjligheter till fortsatt forskning. Vi anser att en undersökning av genomslagskraften i olika sociala medier beroende på segment kan vara värt att vidare studera. Detta för att se hur en optimering marknadsföringen för den valda målgruppen skulle kunna gå till.   Vidare anser vi att en studie av företags relationsbyggande genom sin marknadsföring är intressant. Detta eftersom vår studie visar att relationer har stor betydelse inom upplevelsindustrin, samt att relationer har en stor inverkan på hur vi som individer reagerar på positiv och negativ information gällande företag vi är lojala mot. Studiens bidrag: Ge företag en möjlighet att upptäcka nya kanaler att marknadsföra sig i samt motivera företag som känner en osäkerhet mot sociala medier samt en innovationsspridning om koncepten. / Aim: This paper aims to increase the understanding of how a new company can initiate their marketing in social media and to spread the innovation. Social media is something that lately has grown rapidly and the potential for marketing is great. Method: The paper uses an abductive qualitative method. Empirical data were collected through unstructured interviews, which were then analyzed. The theory is divided according to the marketing mix with the seven p´s and classical marketing theories. Result and Conclusions: The hotel-industry in Gävle is currently experiencing though competition. Several hotels are competing for the same customers. This demands that the hotels create a unique experience that makes the customer return. Because Elite Grand Hotel just recently opened in Gävle makes it difficult to see a concrete result of their efforts in differentiating themself. Suggestions for future research: Because Elite Grand Hotel is newly established, there are great opportunities for further research. We believe that an examination of the impact of various social media depending on the segment may be worth further study. This is to see how an optimization for the selected target group could work. Furthermore, we believe that a study of corporate relationship building through its marketing is interesting. This is because our study shows that relationships are important in experience economy, and that relationships have a big impact on how we as individuals react to positive and negative information regarding the company we are loyal to. Contribution of the thesis: Give businesses an opportunity to discover new marketing channels and motivate business that feel uncertain about social media and spreading the innovation around the concepts.

Load - Maintenance Interaction: Modelling and Optimisation

Townson, Peter Gerard Allan Luke Unknown Date (has links)
All systems are unreliable in the sense that they degrade with age and usage and eventually fail. The degradation depends on the load (or stress) on the system and the maintenance actions. With higher load the productivity increases but this is achieved at the expense of faster degradation and more frequent failures. This in turn reduces the availability of the system. The yield (expected output per unit time), expected operational cost and the expected profit are functions of the load and the availability. The relationship between load and yield is a complicated function and depends on system reliability and maintenance actions. The thesis deals with determining the optimal load and maintenance actions to maximise the yield (or expected profit) or to minimise the expected cost. The thesis comprises of two parts (Parts I and II). Part I is theoretical in nature and looks at the modelling, analysis and optimisation issues. Part II deals with a real case study involving a dragline used in open cut mining. Part I starts with stress-life models which link the load on the system with the reliability of the system. It examines the empirical data in the form of S-N and P-S-N curves, and as WPP plots reported in the literature. The salient features are identified so as to assess the suitability of different models to model the stress-life data. Various Weibull models are assessed to determine their suitability to model stress-life data at the component level. This is followed by a discussion of the modelling at the system level. Optimal maintenance actions are derived based on component level and system level stress-life models. For the component level models, the optimal maintenance actions are derived for a variety of maintenance strategies (such as the age, block and periodic policies) for a specified load to minimise the asymptotic expected cost per unit time. Following this, the joint optimal choice of load and maintenance is examined. For the system level model, the optimal load is obtained to minimise the expected cost per unit time over the life of the system taking into account different actions such as minor and major preventive maintenance actions and corrective maintenance actions. Part II deals with a case study involving a BE1370W dragline. The dragline is used in open cut coal mining to remove the dirt (overburden) on top of the coal seam. This involves dragging the bucket, which is suspended from the boom, through the muckpile until full and then hoisting and swinging the bucket to the dumping point. The capacity of the bucket size determines the load on the dragline. The system level model studied in Part I is used to determine the optimal load to maximise the yield. The dragline was modelled as comprising of 25 components (or sub-systems). Each component was modelled using a system level model of Part I. The model parameters were estimated using real operating and maintenance data over two years. The optimal load to maximise the yield was derived and a sensitivity study carried out.
