Full textAbstract:
Transmission electron microscopy (TEM) has been used to investigate the damage produced following high temperature (350˚C) Xe implantation into [100] Si at fluencies (>1x1016 Xe ions/cm2) and energy (250keV) which produce a buried amorphous layer; and the defect structures produced following thermal anneals of 400˚C, 600˚C or 800˚C for 30 minutes. Analysis of these samples yielded results which suggested that the Xe gas contained within the amorphous layers was swept by the amorphous/crystalline interfaces during solid phase epitaxial re-crystallisation (SPEG) into large bubbles elongated along a direction perpendicular to the interfaces. In order to further investigate this sweeping effect, buried amorphous layers were produced in Si by implanting Li at liquid nitrogen temperature and post implanting the layers with 1x1016 He ions/cm2. Contrary to the spherical bubbles produced under similar conditions in crystalline Si, irregular shaped bubbles were formed in the amorphous layer. Results from in-situ TEM studies showed that these bubbles are mobile at temperatures lower than expected in crystalline Si. Thus, upon reaching the moving interfaces between amorphous and crystalline Si, the bubbles are forced back into the amorphous material which ultimately results in coalescence of the gas into larger bubbles once the two interfaces combine. In addition, microtwins have been shown to form in regions of the re-crystallising layer where there exists an excess of interstitial-type defects. This is contrary to previous microtwin nucleation models which suggested that microtwins are either formed on [111] planes or on bubblesL'endommagement induit par implantation de xénon dans le silicium a été étudié par microscopie électronique à transmission (MET). Les implantations réalisées à 350°C, à une énergie de 250keV et pour des fluences supérieures à >1x1016 Xe ions/cm2 conduisent à la formation d'une couche amorphe enterrée. Les observations effectuées sur les échantillons recuits montrent la présence d'une rangée de grandes cavités allongées dans la direction perpendiculaire à l'interface. Ceci suggère que, lors de la recristallisation du silicium, le déplacement simultané des deux interfaces entraîne le déplacement du gaz jusqu'à son confinement dans de larges bulles. Afin de mieux appréhender les mécanismes qui conduisent au mouvement des bulles, de l'hélium à faible dose a été implanté dans du silicium préalablement amorphisé par implantation de Li à basse température. L'implantation d'hélium dans le silicium amorphe conduit à la formation de bulles de forme irrégulière. Ce résultat diffère du silicium cristallin où des bulles sphériques sont obtenues pour des conditions d'implantation identiques. Les expériences réalisées ‘in situ’ dans le MET montrent clairement d'une part que les bulles sont poussées par l'interface, et d'autre part la nucléation de micromacles. Il a été mis en évidence au cours de cette étude que les bulles sont mobiles à plus basse température dans le silicium amorphe que dans la phase cristalline. Lors de la recristallisation, les bulles se trouvent alors confinées dans le matériel amorphe, ce qui résulte en leur coalescence et à la formation de larges bulles une fois que les deux fronts de recristallisation se sont rejoints. De plus, il a été établi que la formation de micromacles dans la région recristallisée est liée à un excès de défauts de type interstitiels dans la zone amorphe. Ce résultat est contraire aux modèles de la littérature qui suggèrent que les micromacles se forment soit sur des plans {111} soit sur les bulles

En toda la etapa de vida, las mujeres pasan por determinadas experiencias físicas para la conformación de su femineidad como la menstruación, el parto, lactancia, embarazo y menopausia. Los estudios sobre el tema explican que las mujeres enfrentan enfermedades complejas y otras menos severas, algunas enfermedades son: cáncer de ovarios, miomas, ovarios poliquísticos, infecciones, entre otros. Siendo las infecciones la principal causa que lleva a las mujeres al ginecólogo, según el Inem, además, se sabe que mensualmente casi 7 mil mujeres acuden a una consulta ginecológica, de ellos cerca del 70% acuden solo por infecciones (Álvarez et al., 2017).
Por ello, se creó Ammy, una idea de negocio que busca solucionar los problemas relacionados con la salud reproductiva femenina y que funciona a través de una aplicación móvil. El servicio consiste en brindar un monitoreo menstrual con alertador de normalidad o anormalidad del ciclo menstrual, con opción para ingresar los síntomas, de esta manera alertar a la usuaria cuando sus molestias requieran acudir a un ginecólogo, luego de ello, sugerirle un listado de médicos para realizar sus citas médicas por la aplicación de Ammy.
Si bien, en el mercado existen varias aplicaciones extranjeras, lo cierto es que ninguna de ellas permite realizar las consultas médicas virtuales. Además, existen miles de mujeres en Lima que están dispuestas a pagar por este servicio y por las suscripciones para el monitoreo de su ciclo menstrual.
Sin duda este negocio es innovador y muy rentable demostrado en sus indicadores de rentabilidad del presente trabajo.Throughout the life stage, women go through certain physical experiences to shape their femininity, such as menstruation, childbirth, lactation, pregnancy and menopause. Studies on the subject explain that women face complex diseases and others less severe, some diseases are: ovarian cancer, fibroids, polycystic ovaries, infections, among others. Being infections the main cause that leads women to the gynecologist, according to the Inem, in addition, it is known that almost 7 thousand women go to a gynecological consultation every month, of them about 70% go only for infections (Álvarez et al., 2017). For this reason, Ammy was created, a business idea that seeks to solve problems related to female reproductive health and that works through a mobile application. The service consists of providing menstrual monitoring with an alert of normality or abnormality of the menstrual cycle, with the option to enter the symptoms, thus alerting the user when her discomfort requires going to a gynecologist, after which, suggesting a list of doctors to make your medical appointments by the Ammy app. Although there are several foreign applications on the market, the truth is that none of them allow virtual medical consultations. In addition, there are thousands of women in Lima who are willing to pay for this service and for subscriptions to monitor their menstrual cycle. Without a doubt this business is innovative and very profitable, demonstrated in its profitability indicators of this work.

Full textAbstract:
This thesis proposes a computationally effective analytical approach to automated material handling system (AMHS) performance modeling for a simple closed loop AMHS, such as is typical in supporting a 300mm wafer fab bay. Discrete-event simulation can produce accurate assessments of the production performance, including the contribution by the AMHS. However, the corresponding simulation models are both expensive and time-consuming to construct, and require long execution times to produce statistically valid estimates. These attributes render simulation ineffective as a decision support tool in the early phase of system design, where requirements and configurations are likely to change often. We propose an alternative model that estimates the AMHS performance considering the possibility of vehicle-blocking.
A probabilistic model is developed, based on a detailed description of AMHS operations, and the system is analyzed as an extended Markov chain. The model tracks the operations of all the vehicles on the closed-loop considering the possibility of vehicle-blocking. The resulting large-scale model provided reasonably accurate performance estimates; however, it presented some computational challenges.
These computational challenges motivated the development of a second model that also analyzes the system as an extended Markov chain but with a much reduced state space because the model tracks the movement of a single vehicle in the system with additional assumptions on vehicle-blocking.
Neither model is a conventional Markov Chain because they combine the conventional Markov Chain analysis of the AMHS operations with additional constraints on AMHS stability and vehicle-blocking that are necessary to provide a unique solution to the steady-state behavior of the AMHS.
Based on the throughput capacity model, an approach is developed to approximate the expected response time of the AMHS to move requests. The expected response times are important to measure the performance of the AMHS and for estimating the required queue capacity at each pick-up station. The derivation is not straightforward and especially complicated for multi-vehicle systems. The approximation relies on the assumption that the response time is a function of the distribution of the vehicles along the tracks and the expected length of the path from every possible location to the move request location.

Full textAbstract:
Like most ethnic and multicultural narratives, Amy Tan’s The Joy Luck Club revolves around the development of an identity in which immigrant experience and all the questions of ethno- cultural identity that attend to it play central roles. The aim of this essay is to investigate the process of identity formation of the second-generation Chinese immigrant daughters who encounter Chinese culture at home while having the immediate experience of living in America, with a focus on the cultural, language and generational gaps that exist between the Chinese mothers and their American- born daughters. This study is guided by a theoretical framework that combines postcolonial theory and a number of established theories of identity construction including the concept of hybrid identity in order to analyze and explore the American-born daughters’ identity creation. Based on this analysis, this paper presents evidence that an identity formation process that involves cultural hybridization has occurred and the outcome of this identity formation is that of a hybrid identity.

Full textAbstract:
Transitional care is an important process for professionals to consider, particularly as recent studies have shown how a mental health difficulty in adolescence will persist into adulthood. This indicates that a number of those seen in Child and Adolescent mental health services are likely to make the transition into Adult services. For professionals from both services, barriers can arise when supporting young people across service boundaries and recent studies have stated that the current practice of transitional care in mental health is deemed to be problematic. However at the time of conducting this study, there was a paucity of literature, therefore the aim of the study was to add to the existing knowledge. The study followed a Social Constructivist grounded theory (Charmaz, 2014) approach to explore the experience of stakeholders of the transition process. Semi-structured interviews were conducted with professionals, young people and parents. There were a total of eight interviews which were transcribed and analysed. The findings present the core category as Facing the transition, with three sub- categories: Changing status, Manoeuvring the boundaries and Reflections on the process. The tentative theory explains how facing the transition involves stakeholders adjusting to the changing status of the service user. This category triggers the service transition but also describes how societal perceptions about adulthood influence the expectations placed on young people. Manoeuvring the boundaries describes and explains service transition, identifying a range of barriers and strategies to overcome these. One of the most significant barriers was identified as cultural differences between the two services. The third category describes how stakeholders make sense of their experiences, and how these are managed within the therapeutic relationship.

Este trabalho provê um arcabouço de implementação e implantação da Rede de Telecomunicações Aeronáuticas (Aeronautical Telecommunications Network - ATN) no Brasil. Esta futura geração das telecomunicações aeronáuticas é responsável pela integração de uma variedade de sistemas para a troca de dados aeronáuticos, seja ela em enlaces ar-terra ou terra-ar. Diversos aspectos são tratados, principalmente o enlace terra-terra através do Sistema de Tratamento de Mensagens (Message Handling System - MHS) que compõe a ATN. São tratados também a concepção e as necessidades dessa nova rede pela ICAO (International Civil Aviation Organization), passando pelas fases de sua implantação com os gateways entre a atual rede aeronáutica existente e as novas tecnologias de transmissão de dados. Na última parte, o detalhamento de um pequeno grupo de funcionalidades e as operações necessárias a um cenário de troca de mensagens interpessoais no ambiente MHS são cuidadosamente analisados. O trabalho também descreve a tendência de implementação do MHS sobre a pilha de protocolos TCP/IP, em vez da utilização dos protocolos ISO/OSI, exigidos a princípio pela ICAO. Procurou-se oferecer à comunidade aeronáutica as linhas guias para a implantação da rede ATN, explicando e descrevendo a evolução dos Serviços de Tráfego Aéreo (Air Traffic Services - ATS), incluindo o background e os padrões e restrições com os quais a ICAO vem trabalhando. Esta tese de mestrado oferece ainda uma análise prospectiva do futuro das telecomunicações aeronáuticas. Ela pode ser utilizada como base para a investigação das novas tecnologias de transferência de dados aeronáuticos através de ATN, diminuindo o esforço requerido por especialistas da comunidade aeronáutica para compreender os diversos protocolos especificados para esta nova rede que será implantada em escala global.

Full textAbstract:
Uppsatsen önskade undersöka karaktärerna Jo och Amy samt deras relation i Greta Gerwigs film Little Women (2019) ur ett feministiskt perspektiv. Detta gjordes genom att jämföra gestaltningen av dem i Gillian Armstrongs filmadaption av Little Women från 1994 och genom att utgå från Jens Eders karaktärsklocka och feministisk filmteori. Analysen visade distinkta skillnader i gestaltningarna av och relationen mellan karaktärerna samt att dessa innebär ett starkare feministiskt budskap i Gerwigs film. Resultatet visade att Jo hade en än mer feministisk betydelse än i Armstrongs film eftersom hon tydligare motsätter sig hur ett lyckligt slut för en kvinna måste innebära äktenskap med en man. Hon hade också mer tydligt feministiska åsikter och tankar som presenterades i Gerwigs tillagda repliker. Amy fick mer moderna och feministiska värderingar än samma karaktär i Armstrongs film. Amys ambition att bli en duktig konstnär visade enligt denna analys på motivationer utöver de att gifta sig och gjorde att hon indirekt motsäger att hon som kvinna endast är lämpad som fru och i relation till en man. Med hjälp av Eders karaktärsklocka och feministisk filmteori kunde analysen också visa att en karaktärs feministiska budskap kan fokuseras till deras inre aspekter, deras sociala roller, deras symbol och deras symptom. Den yttre aspekten och därmed den visuella njutningen är inte av betydelse för filmens feministiska budskap utan detta kan fokuseras på karaktärernas andra, ovan nämnda, aspekter. Avslutningsvis redovisades hur åskådarens subjektiva upplevelse inte var av väsentlighet eftersom identifiering med karaktärernas känslor och värderingar tillräckligt tydligt förmedlade filmens feministiska budskap.

Full textAbstract:
I tidigare debatter om marknadseffektivitet har diskussioner förts mellan två läger där den ena sidan hävdat att marknaden är effektiv och den andra sidan, ofta med säte i ekonomisk beteendevetenskap, hävdat att systematisk riskjusterad överavkastning går att erhålla. På senare år har diskussionen utvecklats till att utröna om och hur graden av marknadseffektivitet förändras över tid. Den andra sidan gör nu kopplingen att Effektiva marknadshypotesen, en av de ekonomiska teorier som fått störst genomslag, kan samexistera med ekonomisk beteendevetenskap och förklarar att graden av marknadseffektivitet förändras över tid. Denna koppling kallas för Adaptiva marknadshypotesen och är i stor utsträckning vad denna uppsats kommer att behandla. En effektiv marknad innebär att aktiekursen alltid återspeglar det sanna värdet av företaget. En privat investerare gynnas på så sätt av en effektiv marknad då en aktie inte kan vara felaktigt prissatt. I en ineffektiv marknad kan investerare som är duktiga på aktieanalys erhålla systematisk riskjusterad överavkastning. Relativ styrka är en välkänd strategi för aktiehandel som sägs generera riskjusterad överavkastning. Relativ styrka investerar i ett urval av de historiskt bäst presterande aktierna och avyttrar dem en period senare. Tanken är att aktierna ska fortsätta sin positiva utveckling under denna period. I denna uppsats konstrueras en modell med relativ styrka som grund för aktieurval för att mäta graden av riskjusterad överavkastning som går att erhålla med strategin. Detta mått kallas för Alpha. Förändras Alpha över tid som Adaptiva marknadshypotesen förespråkar? Finns det skillnader i hur Alpha förändras över tid mellan segment på börsen? Dessa är några av frågorna som undersöks i studien. Studien bygger på ett kvantitativt tillvägagångssätt med en population av aktier som ingår i Nasdaq OMX Nordic. Aktiepopulationen har delats upp i tre storleksbaserade segment; Large-, Mid- och Small Cap samt ett fjärde segment sammanslaget av de tre förstnämnda segmenten. Undersökningsperioden sträcker sig mellan 2002-10-03 till 2013-05-01 och innefattar tre olika marknadsklimat. Resultaten indikerar att marknadseffektivitet bör betraktas som ett dynamiskt begrepp. Det finns en negativ korrelation mellan några av de observerade segmenten som forskarna tror kan förklaras av att anomalier uppstår och försvinner med jämna mellanrum. Detta gör att analytiker och aktörer på marknaden flyttar sitt fokus till segmentet där anomalin uppstått i hopp om generera avkastning på den felaktiga prissättning som anomalin gett upphov till. I takt med att anomalin utnyttjas så försvinner den från marknaden vilket kan vara en förklaring till varför graden av marknadseffektivitet varierar.

Full textAbstract:
Over the last years, Infineon Dresden Technologies has continuously been working on offering innovative products and enhancing the productivity of their wafer fabrication areas by increasing fab capacities as well as increasing automation in their 200 and 300 mm wafer manufacturing plants to improve productivity. One of the most important success factors is use of powerful automated material handling systems (AMHS) combined with the digitization of core processes within the whole company. Digitization supports converting a highly automated fab into a “smart fab” by horizontal and vertical integration of the internal supply chains. Within this paper, the authors provide an overview of three use cases for continuous improvement of the manufacturing process through use of automation and digitization to enhance the profitability of the semiconductor manufacturing plant.

Full textAbstract:
The latest generation of semiconductor wafer fabs produce Integrated Circuits (ICs) on silicon wafers of 300mm diameter. In this dissertation, we address the following two types of (new) scheduling problems that are encountered in this generation of wafer fabs: multiple-lots-per-carrier scheduling problem (MLCSP) and integrated automated material handling and lot scheduling problem (IMHLSP). We consider several variations of the MLCSP depending upon the number of machines used, the prevailing processing technology of the machines, and the type of objective functions involved. For the IMHLSP, we study two instances, one with infinite number of vehicles and the other with finite number of vehicles.
We begin by introducing a single-machine, multiple-lots-per-carrier with single-wafer-processing-technology scheduling problem for the objective of minimizing the total completion time (MLCSP1). The wafer carrier is a front-opening unified pod (FOUP) that can hold a limited number of wafers. The problem is easy to solve when all the lots are of the same size. For the case of different lot sizes, we first relax the carrier (FOUP) capacity and propose a dynamic programming-based algorithm, called RelaxFOUP-DP, which enables a quick determination of its optimal solution that serves as a lower bound for the problem with limited FOUP capacity. Then, a branch-and-bound algorithm, designated as MLCSP1-B&B, is developed that relies on the lower bound determined by the RelaxFOUP-DP algorithm. Numerical tests indicate that MLCSP1-B&B finds optimal solutions much faster than the direct solution of the MLCSP1 model by the AMPL CPLEX 10.1 Solver. In fact, for the medium and low density problems, the MLCSP1-B&B algorithm finds optimal solutions at the starting node (node zero) itself.
Next, we consider a single-machine, multiple-lots-per-carrier with single-carrier-processing-technology scheduling problem for the objective of minimizing total completion time (MLCSP2). As for the case of MLCSP1, the optimal solution for the case in which all the lots are of the same size can be obtained easily. For the case of different lot sizes, we determine a lower bound and an upper bound for the problem and prove the worst-case ratios for them.
Subsequently we analyze a two-machine flow shop, multiple-lots-per-carrier with single-wafer-processing-technology scheduling problem for the objective of minimizing the makespan (MLCSP3). We first consider a relaxed version of this problem, and transform the original problem to a two-machine flow shop lot streaming problem. Then, we propose algorithms to find the optimal capacitated sublot sizes for the case of lots with (1) the same ratio of processing times, and, (2) different ratios of processing times on the machines. Since the optimal solutions obtained from the lot streaming problem may not be feasible to the MLCSP3, we develop heuristic methods based on the heuristic procedures for the bin packing problem. We develop four heuristic procedures for lots with the same ratio of processing times, and another four procedures for lots with different ratios of processing times on the machines. Results of our numerical experimentation are presented that show that our heuristic procedures generate almost optimal solutions in a matter of a few seconds.
Next, we address the integrated automated material handling and lot scheduling problem (IMHLSP) in the presence of infinite number of vehicles. We, first, propose a new strong hybrid model, which has the advantages of both segregate and direct models. In the segregate model, a job is always transferred to the stocker after its completion at a station, while in the direct model, it is transferred to the next machine in case that machine can accommodate the jobs; otherwise, the job will stay at current station. The decisions involved in the strong hybrid model are the sequence in which to process the lots and a selection between the segregate and direct models for each lot, whichever optimizes system performance. We show that, under certain conditions about the processing times of the lots, the problem can be approximated by the cases of either infinite buffer or zero-buffer at the machines. Hence, we consider all three cases of the IMHLSP in this chapter, namely, infinite buffer, zero-buffer, and limited buffer sizes. For the strong hybrid model with limited buffer size, we propose a branch-and-bound algorithm, which uses a modified Johnson's algorithm to determine a lower bound. Two upper bounds for this algorithm are also determined. Results of our numerical investigation indicate that our algorithm finds optimal solutions faster than the direct solution of the IMHLSP model by the AMPL CPLEX 10.1 Solver. Experimental results also indicate that for the same problem size, the times required to solve the IMHLSP model with interbay movements are larger than those for intrabay movements.
Finally, we investigate the IMHLSP in the presence of limited number of vehicles. Due to the complex nature of the underlying problem, we analyze small-size versions of this problem and develop algorithms for their solution. For some of these problems, we can find optimal solutions in polynomial time. Also, based on our analysis on small-size systems, we have shown why some real-time dispatching (RTD) rules used in real fabs are expected to perform well while not the others. In addition, we also propose some new and promising RTD rules based on our study.Ph. D.

Anti-müllerian hormone (AMH) is expressed in male embryos and represses development of müllerian ducts during testis differentiation in mammals, birds and reptiles. Amh orthologues have been identified in teleosts despite them lacking müllerian ducts. Previously we found sexually dimorphic aromatase activity in tilapia brains before ovarian differentiation. This prompted us to search for further dimorphisms in tilapia brains during sex differentiation and see whether amh is expressed. We cloned the tilapia amh gene and found that it contains 7 exons but no spliced forms. The putative protein presents highest homologies with Amh proteins of pejerrey and medaka as compared to other Perciformes. We analysed amh expression in adult tissues and found elevated levels in testes, ovary and brain. Amh expression was dimorphic with higher levels in XY male brains at 10–15 dpf, when the gonads were still undifferentiated and gonadal amh was not dimorphic. Male brains had 2.7-fold higher amh expression than gonads. Thereafter, amh levels decreased in the brain while they were up-regulated in differentiating testes. Our study indicates that amh is transcribed in male brains already at 10 dpf, suggesting that sexual differentiation may be occurring earlier in tilapia brain than in gonadsDieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Full textAbstract:
La critique de la romancière américaine Amy Tan se concentre principalement sur la dimension humaine de ses romans, négligeant la dimension matérielle de l’existence qui occupe une place prépondérante dans ses romans. Sous l’influence d’une conception anthropocentrique qui privilégie l’être humain ou le sujet, la critique s’est concentrée essentiellement sur la relation mère / fille, sur l’importance du langage et de la mémoire et sur les conflits entre les cultures chinoise et américaine. Néanmoins, dans le contexte de ce qu’il est convenu d’appeler le “retour aux choses” et l’accent nouveau mis sur le “non humain”, mouvement qui s’est mis en place dans la critique des années 1990, je porte mon attention sur les choses, plus particulièrement sur les interactions entre humains et non-humains dans ses romans. Sous la double influence des cultures chinoise et américaine, Tan dépasse l’opposition binaire, qui caractérise la tradition occidentale, selon laquelle le sujet est supérieur à l’objet. Les humains et les non-humains ainsi que les entités naturelles et spirituelles sont tous des choses-Qi dans l’univers textuel. En mettant en dialogue la réflexion occidentale contemporaine sur les choses avec les philosophies chinoises, notamment le taoïsme, cette thèse examine les caractéristiques des choses-Qi et leurs interactions de nature à provoquer un retour écologique à l’harmonie entre les humains et les non-humains, entre le microcosme et le macrocosme dans l’ordre textuelComments on Amy Tan's novels mainly focus on what we associate with human culture, ignoring the material dimensions of existence that figure prominently in her novels. Influenced by the anthropocentric idea that the human being/the subject is superior to things/the object, critics mainly focus on the mother-daughter relation, the importance of language and memory and the conflicts of Chinese and American culture. However, in the context of the so-called “return to things,” “back to things,” and “turn to the non-human” which has become visible in the humanities since the 1990s, I concentrate on things, specifically on the interactions between humans and nonhumans in her novels. Under the influence of both American and Chinese culture, Tan breaks with the western tradition of binary opposition in which the subject is superior to the object. Qi-things include natural and man-made things, human beings, and even spiritual things and things in the textual world. Bringing the twenty-first century western revision of things into dialogue with Chinese philosophies, especially Taoism, this dissertation discusses the traits of Qi-things and how they interact with each other to foster an ecological return to harmony within the textual world that reconciles humans and non-humans, microcosm and macrocosm

Full textAbstract:
Chez la vache le développement des techniques d’induction d’ovulations multiples et de production d’embryons est limité par la variabilité inter-individuelle de la réponse ovarienne au traitement de superovulation. Chez la femme, l’Hormone anti-Müllérienne (AMH) est le meilleur marqueur endocrinien de la réponse folliculaire au traitement de stimulation ovarienne. Les objectifs de mon travail étaient d’étudier l’AMH comme marqueur endocrinien de la réponse ovarienne à un traitement gonadotrope chez la vache et d’étudier la régulation de la production d’AMH par les cellules de granulosa. Nos résultats montrent que les concentrations plasmatiques d’AMH sont prédictives de la réponse ovulatoire à un traitement gonadotrope. Au cours du cycle, les concentrations d’AMH ont un profil en 2 temps : elles diminuent entre les chaleurs et J5 à J8, puis augmentent jusqu’aux chaleurs suivantes. Pour prédire efficacement la réponse ovulatoire, les concentrations d’AMH doivent être mesurées aux chaleurs ou après J12 du cycle. L’étude de la régulation de la production in vitro d’AMH par les cellules de granulosa montre que BMP stimule tandis que FSH inhibe la production d’AMHIn the cow, the development of multiple ovulation and embryo transfer technologies is limited by the variability between animals in ovarian responses to superovulatory treatments. In the women, the anti-Mullerian Hormone (AMH) is the best marker of follicular response to a stimulatory treatment. The objectives of my work were to study AMH as an endocrine marker of the ovulatory response to a stimulatory treatment in the cow and to study the regulation of AMH production by granulosa cells. Our results show that plasma AMH concentrations can predict the ovulatory responses to a stimulatory treatment. During the estrous cycle, AMH concentrations have a dynamic profile in 2 steps: AMH concentrations decrease between estrus and D5 to D8 and then they increase until the next estrus. To predict in optimal conditions, AMH has to be measured at the estrus time or after D12 of the estrous cycle. In vitro, the study about regulation of AMH production by granulosa cells indicates that BMP enhances whereas FSH decreases AMH production

Full textAbstract:
Anti-müllerian hormone (AMH) is expressed in male embryos and represses development of müllerian ducts during testis differentiation in mammals, birds and reptiles. Amh orthologues have been identified in teleosts despite them lacking müllerian ducts. Previously we found sexually dimorphic aromatase activity in tilapia brains before ovarian differentiation. This prompted us to search for further dimorphisms in tilapia brains during sex differentiation and see whether amh is expressed. We cloned the tilapia amh gene and found that it contains 7 exons but no spliced forms. The putative protein presents highest homologies with Amh proteins of pejerrey and medaka as compared to other Perciformes. We analysed amh expression in adult tissues and found elevated levels in testes, ovary and brain. Amh expression was dimorphic with higher levels in XY male brains at 10–15 dpf, when the gonads were still undifferentiated and gonadal amh was not dimorphic. Male brains had 2.7-fold higher amh expression than gonads. Thereafter, amh levels decreased in the brain while they were up-regulated in differentiating testes. Our study indicates that amh is transcribed in male brains already at 10 dpf, suggesting that sexual differentiation may be occurring earlier in tilapia brain than in gonads.Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Full textAbstract:
La chimiothérapie induit une baisse de la fertilité en exerçant une toxicité directe sur les ovaires entrainant une diminution du stock ovocytaire. Couramment utilisé dans le traitement du cancer du sein, le cyclophosphamide (Cy) est une des drogues reconnue comme la plus gonadotoxique. Récemment, il a été proposé que le Cy provoquait une déplétion folliculaire par une entrée en croissance massive des follicules au repos. L’Hormone Anti-Müllérienne (AMH) étant un des facteurs régulant la sortie des follicules primordiaux de la réserve ovarienne, nous avons émis l’hypothèse que cette hormone pourrait limiter la gonadotoxicité du Cy. Nous avons montré qu’un traitement par AMH recombinante chez des souris pubères traitées par Cy, permettait effectivement de limiter la déplétion folliculaire. Sur le plan fondamental, nous avons mis en évidence que l’autophagie pouvait être un des mécanismes impliqués dans l’inhibition du recrutement folliculaire exercée par l’AMH. Enfin, la méthode de référence consistant à évaluer la réserve ovarienne chez la souris étant particulièrement longue et fastidieuse, nous avons développé une technique de comptage folliculaire automatisé en utilisant des méthodes d’intelligence artificielle, et plus particulièrement une approche de « deep learning»Chemotherapy induces infertility by exerting a direct toxicity on the ovaries, resulting in a depletion of the follicular stockpile. Cyclophosphamide (Cy), widely used for breast cancer, is recognized as one of the most gonadotoxic agent. Recently, it has been proposed that Cy gives rise to follicular depletion by a massive growth of resting follicles which are then destroyed. Since Anti-Müllerian Hormone (AMH) is one of the factors regulating primordial follicles activation, we hypothesized that this hormone might limited Cy-induced gonadotoxicity. We have shown in pubertal mice that recombinant AMH injections are able to preserve primordial follicle loss Cy-induced and might improve fertility outcome after treatment. In addition, we provide evidence that autophagy could be one of the mechanisms involved in the inhibition of follicular recruitment by AMH. At least, nowadays, the “gold standard” method of evaluating ovarian reserve in mouse is a process particularly time-consuming and tedious. We developed a new methodology of automatic primordial follicles detection and counting within mouse ovaries, using modern artificial intelligence methods, especially deep learning approach

In this study, we start characterizing the spermatogonial niche in carp by evaluating amh expression in testes with high or low proliferative activity. 20 adult carp received pulses of BrdU (5-Bromo-2’-deoxyuridine), during 3 consecutive days (2 intraperitoneal injections/day), and testis was sample dafter 4 hours, and 1, 2 and 3 weeks after the last pulse. Type Aund were the only germ cells able to retain BrdU after a long period of chase (3 weeks). Interestingly, BrdU disappeared more quickly from -active? stem cell while in -reserve? stem cell, it remained stable. The -reserve? stem cell label-retaining cells were located near the interstitium, while -active? stem cell were found in the intertubular area. Some Sertoli cells were BrdU-positive after 3 weeks of pulse. Among the slow-dividing, BrdU-positive Sertoli cells, ~30-40% are -free?, and ~60-70% associated with germ cells. This suggests the existence of Sertoli stem cells which are located in the spermatogonial niche. The amh gene was cloned and characterized in common carp, and the amh is expressed in Sertoli cells involving undifferentiated spermatogonia. The follicle stimulating hormone and estrogen decrease amh expression. It was also shown that animals with high expression of amh, have low proliferative activity. When the testes with high proliferation, amh levels decrease significantly. Thus, it is suggested that counts down the amh creates a permissive condition for proliferation and differentiation of spermatogonial in carp. These results provide a basis for applying this knowledge to mediate early puberty in exotic/native species economically important in aquaculture

Amy Tan, the author of The Joy Luck Club (1989), The Kitchen God’s Wife (1991), The Hundred Secret Senses (1995), The Bonesetter’s Daughter (2001), and Saving Fish from Drowning (2005), is accused of being a “fake” Chinese American writer by radical Chinese American critics such as Frank Chin. I consider Tan’s fictional writing of the experience of Chinese immigrant mothers and their American born daughters to be an experiment in cross-cultural communication. Such communication may be highly personal and subjective to Tan, who claims to write so that her mother can understand her feelings and to remember what she has learned from her Chinese side. I also believe her writings create an opportunity for bi- (or cross-) cultural communication and it matches the concept of harmony in Chinese traditional philosophy.
In Chinese scholar Jianjun Zou’s opinion, Tan’s works represent the notion of reconciliation, and that all of these works shall be viewed as a whole is the inspiration of this thesis. Reconciliation in terms of Tan’s works has three parts, which are: (1) the reconciliation between languages; (2) the reconciliation between genders; (3) the reconciliation among generations. The existence of reconciliation proves that Tan’s writing about the Chinese community is multi-dimensional. From my point of view, she should not be simply defined as a stereotype writer whose works can only reinforce the prejudices against the Chinese community and Chinese men. In my opinion, for Chinese American criticism, violation of the women’s right to tell of the oppression from the Chinese traditional family values should not be the solution to the prejudices of the white dominant culture. For Chinese critics in Chinese speaking regions, especially in China, I suggest that we should have a humble attitude towards the Chinese American literature because the “real” and the “fake” are difficult to define, even in the motherland of Chinese culture.

Full textAbstract:
Introdução: O processo de envelhecimento reprodutivo ocorre em virtude do declínio progressivo na quantidade e qualidade de óvulos que se inicia após a puberdade, se mantém ao longo da menacme, com redução gradual da fertilidade, e termina na menopausa, caracterizada pelo esgotamento do número de folículos e, consequentemente, da reserva ovariana funcional (ROF). A vida pré-natal constitui um importante período para o desenvolvimento dos órgãos genitais internos femininos e mudanças nessa fase podem ter repercussões futuras: quando o feto é submetido a condições adversas intrauterinas, mecanismos metabólicos e endócrinos de adaptação podem mudar o eixo metabólico pós-natal predispondo a certas doenças na vida adulta. Com base nesses dados, postulou-se que condições desfavoráveis de vida intrauterina que poderiam se refletir com alterações do peso ao nascer (PN) poderiam levar à reprogramação de genes envolvidos no controle da ROF e que talvez nascer pequeno para idade gestacional (PIG) ou grande (GIG) possibilitaria a interferência com a ROF estimada por meio das concentrações séricas do hormônio antimülleriano (AMH). Objetivos: O objetivo deste estudo foi avaliar a relação do PN com a ROF, estimada por meio da concentração sérica do AMH em mulheres na menacme com 34 a 35 anos de idade. Pacientes e Métodos: Trata-se de um estudo transversal aninhado a uma coorte de mulheres que nasceram no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP), no período de 01 de junho de 1978 e 31 de maio de 1979. O desfecho primário avaliado foi a concentração sérica de AMH, um marcador da ROF, e sua correlação com o PN, divididos em três grupos: PIG, adequado para a idade gestacional (AIG) e GIG. Resultados: Das 274 pacientes incluídas no estudo, 19 foram classificadas como PIG, 238 como AIG e 17 como GIG. As concentrações médias de AMH não foram significativamente diferentes (p=0,11) entre mulheres na menacme nascidas PIG, AIG e GIG (2,14 ng/mL, 2,13 ng/mLe 2,57 ng/mL, respectivamente). Conclusão: Não se observou diferença nas concentrações séricas de AMH entre mulheres nascidas PIG, AIG e GIG avaliadas entre 34 e 35 anos de idade. A casuística avaliada permitiu detectar ou descartar uma grande diferença entre os grupos (effectsize de 0,7). Dessa forma, evidenciou-se que o PN não apresenta grande influência sobre a ROF, estimada pelas concentrações séricas do AMH, em mulheres na menacme, entre 34 e 35 anos de idade. Caso novos estudos evidenciem que diferenças pequenas ou moderadas nas concentrações séricas do AMH possam apresentar relevantes repercussões clínicas em mulheres nesta faixa etária, outras pesquisas serão necessárias, sendo os dados do presente estudo úteis para o cálculo amostral.Background: The reproductive aging process occurs by a progressive decline in the quantity and quality of oocyte, starting after pubertal onset, remaining through menacme with gradual reduction of fertility and ends with menopause, which is the depletion of ovarian follicles and hence the depletion of functional ovarian reserve (FOR). Prenatal life corresponds to a critical window for the development of female internal genitalia and changes at this stage may have future repercussions: when the fetus is submitted to intra uterine adverse conditions, adaptive metabolic and endocrine mechanisms will change the metabolic axis in the postnatal period thereafter predisposing to several diseases in adulthood. Based on this correlation, we postulate that unfavorable conditions of intrauterine life that could reflect on birth weight (BW) could lead to the reprogramming of genes involved in the control of FOR and that maybe being born small for gestational age (SGA) or large for gestational age (LGA) could interfere with the FOR estimated through serum concentrations of Anti-Müllerian hormone (AMH). Objective: To investigate the relationship between BW and ROF estimated through AMH serum concentration in menacme women with 34-35 years old. Patients and Methods: This is a prospective birth cohort assessing all women who were born in Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP) between June 1, 1978 and May 31, 1979. The primary endpoint was to evaluate serum AMH concentration, a marker of FOR and its correlation with BW divided into three groups: SGA, adequate for gestational age (AGA) and LGA. Results: Out of the 274 patients included in the study: 19 were classified as SGA, 238 as AGA, and 17 as LGA. The average of AMH concentrationwas not significantly different (p=0.11) among women in reproductive age born SGA, AGA and LGA (2.14 ng/mL, 2.13 ng/mL, and 2.57 ng/mL respectively. A variance analysis between the three groups and OR did not find a significant different between them (p=0.11). Conclusion: There was no difference in serum AMH concentration in women born SGA, AGA and LGA with 34 to 35 years old. This sample also allowed to detect or rule out a major difference between the groups (effect size of 0.7). In conclusion, BW does not have a great influence on FOR, estimated through serum AMH concentration in menacmewomen, between 34 and 35 years old. If new studies show clearly that small or moderate differences in serum AMH concentration could impact clinical outcomes in women at this age, further studies will be needed, and the data of this study could be useful for sample size calculation.

Full textAbstract:
There are two traditions in English poetry: elevated and down-to-earth. The former is characterized by formal style, use of verbal associations, and philosophical subject matter. The latter is informal, uses worldly images and makes specific points. When elevated style uses common language, i.e. words drawn from specialized contexts, those words bring with them the down-to-earth spirit. They convey an effect of honesty, indicting the abstraction of elevatedness as an evasion. John Ashbery calls up that effect to discredit it, to show that down-to-earth poetry's implied access to the world is delusive and his personalized internal view is honest. Amy Gerstler accepts the indictment, letting it bring her poems to an epiphanic connection with reality. This distinction reflects their generational difference, between Ashbery's postmodernists who see no possibility of understanding reality, and Gerstler's post-postmodernists who instinctively hope for that understanding while accepting postmodernist epistemological pessimism.

Undersökningsenheterna består av OMX Stockholm All Share Index samt aktiemarknadens, utifrån marknadskapitalisering, fem största sektorindex. Med en robust metodologi kartlägger vi effektivitetsdynamiken mellan prisserierna under åren 2000-2013 och finner stöd för den adaptiva marknadshypotesens förmenanden utifrån såväl marknadsindex som majoriteten av undersökta sektorindex. Studien påvisar också att effektivitetsanalys utifrån marknadens beståndsdelar åskådliggör effektivitetsdynamik inom marknaden, på ett sätt som analys av endast marknadsindex missar. Kartläggning utifrån sektorer visar även att förändringar i marknadsmiljön kan ge upphov till adaptiva ineffektiviteter på isolerade marknadssegment, och erbjuder därmed utveckling av AMH som i sin nuvarande form endast beaktar homogen förmåga för marknaden att bearbeta och inkorporera förändringar. Detta belyser betydelsen av diversifiering med avseende på effektivitet vid investeringsbeslut. Riskindikatorer för ineffektiviteter i respektive sektor samt korrelationsmatris över sektorers samvarierande effektivitet tas därför fram som initiala beslutsunderlag och komplement till traditionell portföljvalsteori. Ända sedan den effektiva marknadshypotesen formulerades av Eugene F. Fama för snart ett halvt sekel sedan har marknadseffektivitet debatterats kraftigt inom den finansiella forskningen. Den adaptiva marknadshypotesen erbjuder en ytterst tilltalande förklaring till marknadens beteende, där konsolidering mellan förespråkare för EMH och finansiell beteendevetenskap möjliggörs. Teorins potential att föra fundamental finansforskningen framåt har därför gjort att AMH, trots sin ringa ålder, snabbt fått uppmärksamhet inom forskningsdiskursen, och det är också av dessa anledningar vi sökt testa och samtidigt utveckla teorin och dess implikationer i en svensk kontext.

La compréhension de la régulation de l’AMH et de son récepteur spécifique, l’AMHR2, par les BMPs a amené un éclairage nouveau sur leur rôle dans le développement folliculaire et la régulation du taux d’ovulation. Nos résultats se basent sur l’étude de 4 modèles ovins porteurs de mutations Fec, mutations qui affectent des membres de la famille des BMPs, à savoir leur ligand BMP15 ou leur récepteur. Ces mutations se traduisent phénotypiquement par une baisse de l’expression de l’AMH ou de son récepteur dans les cellules folliculaires, et des ovulations multiples chez les brebis porteuses. D’un point de vue mécanistique, nos résultats ont mis en évidence une régulation de l’AMH et de l’AMHR2 par les BMPs in vivo et in vitro, passant par le récepteur BMPR1B, et s’exerçant sur l’activité transcriptionnelle du promoteur de l’AMH via SMAD1 et SF1. Cette régulation a également été en partie mise en évidence dans l’espèce porcine avec une observation supplémentaire dans ce modèle : un taux d’ovulation naturellement très élevé est associé à une faible production ovarienne d’AMH. Ces observations mettent en exergue le rôle possible de l’AMH dans la régulation du taux d’ovulationThe understanding of the regulation of AMH and its specific receptor, AMHR2, by the BMPs, brought a new highlight on their role in the regulation of follicular development and the control of ovulation rate. Our results are based on the study of 4 sheep models carrying Fec mutations which affect different members of the BMPs family, namely their ligand BMP15 or their receptor, Mutations result phenotypically in a low expression of AMH or AMHR2 in the granulosa cells of ovarian follicles, and multiple ovulations in carrier ewes.. From a mechanistic point of view, the results demonstrated the in vivo and in vitro regulation of AMH and AMHR2 by BMPs, acting through the BMPR1B receptor and enhancing the transcriptional activity of the AMH promoter via SMAD1 and SF1. This regulation has also been partially demonstrated in swine with an additional observation in this model: a naturally high ovulation rate is associated with a low ovarian production of AMH. In conclusion, these observations show a possible role of the AMH in the regulation of ovulation rate

Introdução: Considerando a prevalência, a importância social dos tratamentos de alta complexidade de mulheres inférteis e o contexto atual da literatura que atribui relevância aos polimorfismos dos genes reguladores do desenvolvimento inicial e crescimento folicular, entre eles o FSHR, LH, LHR, AMH, AMHR, BMP15 e GDF9; torna-se imprescindível o melhor conhecimento e a quantificação desses fatores. Com isso poderemos individualizar e abordar de forma mais racional a investigação e o tratamento destas mulheres submetidas à fertilização in vitro (FIV). Objetivos: Avaliar se os polimorfismos dos genes do LH (Trp8Arg e Ile15Thr), AMH (Ile49Ser), BMP15 (673C/T, 9C/G, IVSI+905A/G), GDF9 (546G>A, 398C>G, 447C>T e 646G>A), e dos receptores do FSH (Ser680Asn), do LH (18isnILQ) e do AMH (Ile49Ser), estão relacionados a diferentes desfechos reprodutivos em pacientes submetidas à fertilização in vitro. Métodos: Realizamos dois estudos em mulheres submetidas à indução ovulatória para FIV: (1) um estudo caso-controle entre pacientes normo respondedoras e má respondedoras, (2) um estudo transversal em pacientes jovens submetidas à indução ovulatória para fertilização in vitro (FIV). Foi extraído DNA das pacientes submetidas à indução ovulatória para FIV a partir do sangue periférico para realização de polymerase chain reaction, com o objetivo de detectar os polimorfismos dos referidos genes e as respectivas relações com os resultados obtidos na estimulação ovariana, no Laboratório de Terapia Gênica do HCPA/UFRGS. Resultados: Foi evidenciado que a presença do polimorfismo 398C>G no gene GDF9 está associada à má resposta em pacientes inférteis submetidas à estimulação ovariana para fertilização in vitro (68% em má respondedoras versus 23% normo respondedoras, OR: 4.01, 95% IC:1.52-10.60). Além disso, o genótipo mutante para o polimorfismo G447C>T no gene do GDF9 foi encontrado em 50% nas pacientes má respondedoras versus 19% nas pacientes normo respondedoras (OR: 2.88, 95% IC:1.19-6.04), evidenciando uma forte associação destes polimorfismos com a má resposta ovariana à estimulação. Encontramos, também, que as mulheres portadoras do alelo mutante do gene 447C>T do GDF9 tiveram um número menor de folículos entre 12-14 mm no dia do hCG (1,62 versus 2,46, P = 0,007). As mulheres com o alelo mutante do gene do GDF9 398C>G tiveram um menor número de folículos maiores que 17 mm no dia do hCG (4,33 versus 6,49, P = 0,001), menor número de folículos entre 12 e 14 milímetros no dia do hCG (1,42 versus 2,25, P= 0,017), um menor número de folículos no dia do hCG (7,33 versus 10,11 versus, P = 0,007), e redução total de oócitos MII coletados (5,38 versus 8,84 P = 0,017). Conclusão: Concluímos que polimorfismos no gene do GDF9 têm uma influência significativa no desenvolvimento do oócito, uma vez que a presença dos alelos mutantes 447C>T e 398C>G diminui o número total de folículos maduros e o número total de oócitos coletados de tais pacientes, além deste último estar associado à má resposta ovariana em pacientes submetidas à indução da ovulação para fertilização in vitro. Isso mostra que este membro da família TGFβ além de atuar nas fases iniciais da foliculogênese também tem influência importante sobre a fase final do desenvolvimento do oócito.Introduction: Given the prevalence, the social importance of high complexity treatments of infertile women and the current context of the literature assigns relevance to polymorphisms of genes regulating early follicle growth and development, including LH, AMH, BMP15, GDF9, FSHR, LHR and AMHR; become essential to better understanding and quantification of these factors. With this we can individualize and address more rationally research and treatment of these women undergoing IVF. Objectives: Evaluate the relationship of polymorphisms of LH (Trp8Arg andIle15Thr), AMH (Ile49Ser), BMP15 ( 673C/T, 9C/ G, IVSI+905A/ G) and GDF9 (546G>A, 398C>G, 447C>Tand646G>A) genes, and FSH (Ser680Asn), LH (18isnILQ) and AMH (Ile49Ser) receptors genes, related to different reproductive outcomes in patients undergoing IVF. Methods: Our study consisted of two phases: the first conducted a case-control study among patients with normal responders and poor responders, and the second a cross-sectional study in young patients undergoing ovulation induction for in vitro fertilization. DNA was extracted from peripheral blood for performing polymerase chain reaction (PCR) and analyzed at the Laboratory of Gene Therapy HCPA/UFRGS, with the objective of detecting polymorphisms of these genes and their relationships to the results obtained in ovarian stimulation. Results: It was shown that the presence of polymorphism 398C>G in GDF9 gene is associated with poor response in infertile patients undergoing controlled ovarian stimulation for in vitro fertilization (68% in poor responders versus 23% in normal responders). Furthermore, the genotype GDF9 447C>T mutant polymorphism was found in 50% and 19%, respectively, in poor and normal responders patients, showing a strong association with this polymorphism and a poor response in ovarian stimulation. Women carrying the GDF9 398C>G mutant allele had a smaller number of follicles between 12-14 mm on the day of r-hCG (1.62 vs. 2.46, respectively P=0.007). Women with GDF9 398C>G mutant allele had a smaller number of follicles larger than 17 mm on the r-hCG day (4.33 vs. 6.49, P=0.001), a smaller number of follicles between 12 and 14mm on the r-hCG day (1.42 vs. 2.25, P=0.017), a smaller number of follicles on the r-hCG day (7.33 vs. 10.11, P=0,007), and a reduced overall number of MII oocytes collected (5.38 vs. 8.84 ,P=0.017). Conclusion: We conclude that GDF9 polymorphisms in the gene have a significant influence on the development of the oocytes, since the presence of the mutant alleles 447C>T and 398C>G decreases the total number of mature follicles, total number of oocytes collected, and are associated a poor ovarian response in patients undergoing ovulation induction for in vitro fertilization. This shows that this member of the TGFβ family besides acting in the early stages of folliculogenesis also has important influence on the final stage of oocytes development.

Full textAbstract:
This analysis of Tan's first two novels reveals that her female characters suffer from the strains critics like Amy Ling say result from the double paradox of filling the roles of mother or daughter as minority women in a white, male society. Recognizing this double paradox offers Tan's characters, and her readers, the opportunity to resolve the conflicts between mothers and daughters in The Joy Luck Club. Using the theories of psychologist Kathie Carlson helps readers understand how the protagonist of The Kitchen God's Wife resolves similar conflicts with her daughter and her own mother by seeking support from a mythic mother-figure, a Goddess of her own making.

Wong, Hiu Wing. ""Talk-stories" in the fictions of Maxine Hong Kingston and Amy Tan." Thesis, University of Warwick, 2006. http://wrap.warwick.ac.uk/1183/.
Full textAbstract:
This thesis investigates the "talk-story" narrative patterns, which stem from the Chinese oral tradition, in selected works of two contemporary Chinese American women writers, Maxine Hong Kingston and Amy Tan. In The Woman Warrior, Kingston has experimented with a new kind of "talk-story" writing in blending family stories, cultural myths, fantasy, autobiographical details, and history, as she attempts to model her work on the familial talk-story culture she was nurtured in. Borrowing the term "talk story" from a pidgin Hawai'ian expression, Kingston develops a special kind of generic "talk-story" as an artistic creation in her fictions. Amy Tan's The Joy Luck Club is often compared to The Woman Warrior and a number of critics have observed the use of "talk-story" in Tan's novels, but the talk-story components in the two writers' works have been largely discussed in relation to the mother-daughter dyads and few critics have distinguished the different usages and functions of "talk-stories" in their works. Through a literary analysis of their works, my thesis attempts to enrich the concept of "talk-story" originated from Kingston, and discusses its relation to the works of Kingston and Tan, with an aim to teasing out the two writers' differences within their sameness. While Kingston exhibits a talk-story narrative structure in her works, Tan mainly confines the talk-story elements at a textual level as a healing narrative therapy between generations. I will argue that while both writers exemplify talk-story as a form of self-expression and empowerment, their talk-stories function differently as they interact with the mainstream discourse: while Kingston remodels the Chinese talk-story pattern by making it a form of literary art, Tan refashions talk-story as a kind of "talking-cure, " as in western psychotherapy, in her fictions and writes in the popular arena.
