The Design and Analysis of Large Display Groupware

Huang, Elaine M. 11 April 2006 (has links)
Despite the proliferation of large-scale displays in the workplace, creating groupware applications that take advantage of their potential for collaboration and communication remains a challenge. Interactions with large displays yield user experiences that are quite different from interaction with conventional desktop groupware. Thus, unique hurdles exist for designing and deploying large display groupware applications (LDGAs) that are useful and adopted into actual work practice In this dissertation we uncover and address some of the primary challenges for large display groupware applications though the design, development, deployment and evaluation of LDGA systems, as well as through the analysis of existing deployed LDGA systems. We present novel LDGA designs that address the issues of information awareness and informal communication through the use of large shared displays in workplaces and describe the findings from evaluations of their deployments. We then discuss a broad study of several existing LDGAs that we conducted and a framework of adoption challenges that we subsequently derived. We describe the application of this framework to the design a large display groupware application for supporting lightweight communication among workgroup members. We also present a field study of the use of LDGAs within the context of multi-display environments, looking specifically at the display technologies used by NASA scientists and engineers for the Mars Exploration Rover (MER) missions. This work uncovers how the display environment provides flexible support for science tasks as collaboration styles and mission goals evolve. We offer suggestions for how LDGAs should be designed and evaluated in light of our findings regarding the roles of LDGAs within an ecology of displays. Finally, we use the results of this evaluation as input for further refining our framework for LDGA adoption challenges.

Tanssiesitys auttamismenetelmänä dementoituvien vanhusten hoitotyössä

Ravelin, T. (Teija) 28 October 2008 (has links)
Abstract The aim of this study was to describe and evaluate the use of dance performance as an intervention in the care of elderly persons with dementia. The research task was to describe and evaluate how demented elderly persons experience dance performances and describe dance performance and its essence as an intervention. The method was qualitative evaluation research. The informants were demented elderly persons (13), their family members (4), nurses (7) and practical nurse students (3). Four dance performances based on elderly persons' memories of different seasons were performed in the nursing home. The data were collected using individual interviews of elderly persons, videotaping, heart rate measurements and focus group interviews of family members, nurses and students. The experiences of the demented elderly persons were related to dance performance as an activity, dance performance, performers, themselves, and to the audience and surroundings. Dance performance was evaluated as a process intervention with an effect on the elderly person and his/her interaction with the others and also on the family members. Dance performance as an intervention in the care of elderly persons with dementia has its own special features as does its implementation in nursing. Watching a dance performance is an active event to the demented elderly person. Feelings, memories and sense of community with the others aroused by dance performance are positively significant in the nursing care context. Dance performance is an interactive psychosocial intervention which promotes the well-being and elicits the resources of the elderly person with dementia. It can also be a contradictory intervention. This study has produced information for gerontological nursing. With this information dance performance can be used in similar situations as a goal-directed intervention. / Tiivistelmä Tämän tutkimuksen tarkoituksena oli kuvata ja arvioida tanssiesityksen käyttöä auttamismenetelmänä dementoituvien vanhusten hoitotyössä vanhusten, omaisten, hoitajien ja lähihoitajaopiskelijoiden näkökulmista. Tutkimuksen tehtävänä oli kuvata ja arvioida miten dementoituvat vanhukset kokevat hoitoyhteisöihin tuodut tanssiesitykset, kuvata tanssiesitystä auttamismenetelmänä dementoituvien vanhusten hoitotyössä dementoituvien vanhusten, omaisten, hoitajien ja lähihoitajaopiskelijoiden arvioimana sekä kuvata, millainen tanssiesityksen tulee olla auttamismenetelmänä dementoituvien vanhusten hoitotyössä. Tutkimus oli laadullinen arviointitutkimus. Siihen osallistui 13 dementoituvaa vanhusta, 4 omaista, 7 hoitajaa ja 3 lähihoitajaopiskelijaa. Hoitokodissa esitettiin neljä vanhusten vuodenaikamuistoihin perustuvaa tanssiesitystä. Aineistonkeruumenetelminä olivat dementoituvien vanhusten yksilöhaastattelut, videointi, sykemittaukset sekä omaisten, hoitajien ja lähihoitajaopiskelijoiden ryhmähaastattelut. Aineistot kerättiin neljän tanssiesityksen yhteydessä ja jälkeen. Aineistot analysoitiin laadullisella, induktiivisella sisällön analyysimenetelmällä. Vanhusten kokemukset tanssiesityksistä liittyivät tanssiesitystoimintaan, tanssiesitykseen, esiintyjiin, heihin itseensä sekä toisiin katsojiin ja ympäristöön. Tanssiesitys arvioitiin prosessina toteutuvaksi auttamismenetelmäksi, joka vaikuttaa vanhukseen ja hänen vuorovaikutukseensa toisten kanssa sekä omaisiin. Dementoituvien vanhusten auttamismenetelmänä toimivalla tanssiesityksellä on omat erityispiirteensä tanssiesityskokonaisuuteen, tanssiesityksen kokonaistunnelmaan, rakenteeseen, kestoon, sisältöön, visuaalisuuteen, äänimaailmaan, esiintyjiin ja ympäristöön liittyen. Tanssiesityksen hoidollisella hyödyntämisellä on myös omat erityispiirteensä. Tanssiesityksen katsominen on dementoituvalle vanhukselle aktiivinen tapahtuma, ja tanssiesityksen herättämät tunteet, muistot ja yhteisyys toisten kanssa saavat aikaan prosesseja, joilla on myönteistä hoidollista merkitystä. Tanssiesitys on vuorovaikutuksellinen, hyvinvointia edistävä ja vanhuksen voimavaroja esille nostava psykososiaalinen auttamismenetelmä, jonka avulla voidaan tukea dementoituvan vanhuksen normatiivista kehitystä. Tanssiesitys ei ole ristiriidaton auttamismenetelmä, ja sen hoidollisen hyödyntämisen lähtökohtana tulee olla dementoituvan vanhuksen yksilölliset tarpeet. Tutkimus on tuottanut tietoa kliinisen, gerontologisen hoitotieteen tietoperustaan tuomalla laadullista tutkimusnäyttöä aiemmin tutkimattomasta auttamismenetelmästä. Tuotetun tiedon avulla tanssiesityksiä voidaan hyödyntää vastaavissa tilanteissa tavoitteellisesti auttamismenetelmänä.

Integralidade e humanizaÃÃo em saÃde mental: experiÃncias de usuÃrios em dois centros de atenÃÃo psicossocial / Completeness and humane mental health: user experiences of two psychosocial care centers

AndrÃa Batista de Andrade 20 June 2012 (has links)
A implementaÃÃo de polÃticas pÃblicas de saÃde mental na conjuntura do Sistema Ãnico de SaÃde, baseada nos preceitos da Reforma PsiquiÃtrica, enseja novos desafios para a Ãrea, tais como a produÃÃo de redes substitutivas e territoriais que visem à superaÃÃo do modelo hospitalocÃntrico, à conquista de cidadania e à criaÃÃo de um novo lugar social para a experiÃncia do sofrimento psÃquico. Para garantir a materialidade dessas mudanÃas, faz-se necessÃria a participaÃÃo efetiva dos usuÃrios na avaliaÃÃo de serviÃos e programas de saÃde mental. Destarte, esta investigaÃÃo objetiva compreender as experiÃncias de usuÃrios em dois Centros de AtenÃÃo Psicossocial (CAPS) de Fortaleza-CearÃ, no que concerne à assistÃncia conferida pelos profissionais, exprimindo destaque Ãs dimensÃes integralidade e humanizaÃÃo do cuidado em saÃde. A escolha da abordagem qualitativa como metodologia desta pesquisa està relacionada à natureza ontolÃgica do objeto em foco, visto que esta à permeada de significados que os usuÃrios atribuem Ãs suas experiÃncias nos serviÃos de saÃde mental e à maneira como compreendem e interpretam as prÃticas assistenciais. As tÃcnicas utilizadas para a obtenÃÃo do material empÃrico foram a entrevista em profundidade e a observaÃÃo nÃo estruturada, nos meses de julho a dezembro de 2011. Os dados foram analisados e interpretados sob a Ãptica da HermenÃutica-crÃtica gadameriana, cujo mÃtodo assume a intersubjetividade na interconexÃo com a materialidade a que se vincula de maneira dialÃtica. Os resultados evidenciaram trÃs temas centrais que constituÃram a Rede de Significados: A) ExperiÃncias dos itinerÃrios terapÃuticos; B) PercepÃÃo dos usuÃrios sobre o serviÃo; e C) Qualidade do cuidado. Destaca-se o impacto dos diferentes modelos asilar e psicossocial na experiÃncia vivida dos usuÃrios dos distintos CAPS. Observou-se, tambÃm, que os usuÃrios percebem o acolhimento, a resolubilidade, a ambiÃncia, a boa interaÃÃo dos profissionais-usuÃrios, o agenciamento de medicamentos e a humanizaÃÃo como os principais aspectos concernentes ao atendimento de qualidade em saÃde mental - embora tais questÃes, em alguns momentos, tenham se revelado de maneira singular nos dois dispositivos desta pesquisa. Conclui-se que, apesar de alguns entraves, os aspectos da assistÃncia apontados pelos usuÃrios dos distintos CAPS corroboram os ideais da Reforma PsiquiÃtrica e sinalizam que a reorientaÃÃo do modelo de atenÃÃo em saÃde mental jà se capilariza no cotidiano das prÃticas de cuidado. / The implementation of public mental health policies in the context of the Unified Health System (SUS), based on the precepts of the Psychiatric Reform, has generated new challenges for the mental health area such as the deployment of territorial and substitutive networks aiming the overcoming of the hospital-centered model, the development of the citizenship and the creation of a new social site for experiencing the psychic distress. To guarantee the materiality of changes, it is necessary the effective participation of users in the evaluation of mental health programs and services. Thus, the current research aims to understand the user experiences of two CAPS (Center for Psychosocial Care) in the Fortaleza city, concerning to the care provided by professionals, highlighting the dimensions comprehensiveness and the humanization on the health care. Regarding the methodology of this research, the choice for the qualitative approach is related to the ontological nature of the research object because this nature is pervaded by meanings which the users pose on their experiences on health care services and the way how they understand and interpret such care practices. The techniques used to obtain the empirical material were the detailed interview and the unstructured observation, in a time period of two months, from July to December 20011. The data were analyzed and interpreted under the perspective of the GadamerÂs critique hermeneutics whose method assumes the inter-subjectivity in the interconnection with the materiality to which it binds in a dialectic manner. The results revealed three central themes which constitute the Network of Meanings: A) The experiences on therapeutics itinerary; B) the user perception on the services, C) The quality of the care. We highlight the impact of the distinct models, hospital-centered and psychosocial, in the experience lived by distinct CAPS users. We also observed that the user perceive the embracement, the resolvability, the ambience, the good interaction between professionals and users, the monitoring of medicines and the humanization as the main aspects concerning to the quality of mental health care, although such issues had presented themselves in a singular way in the two CAPS investigated. We conclude that, despite some obstacle, the aspects of care pointed by users of the distinct CAPS corroborate the ideals of the Psychiatric Reform and signalize that the reorientation of the health care model already makes capillary in the daily care practices.

Le Service à la famille de l'organisme Dans la rue : points de vue et expériences de jeunes qui y ont fait appel

Jastremski, Mélanie 09 1900 (has links)
Malgré l’intérêt accru du public et de la recherche durant les deux dernières décennies pour le phénomène des jeunes de la rue, certains aspects de leurs réalités sont encore peu examinés et mal connus. L’un de ces aspects concerne la parentalité. Pour mieux comprendre les besoins des jeunes en situation de rue qui sont parents ou en voie de l’être et comprendre dans quelle mesure un service s’adressant spécifiquement à eux arrive à y répondre, cette étude a cherché à décrire et comprendre l’expérience d’utilisation du Service à la famille de l’organisme Dans la rue, telle que vécue par des jeunes qui s’y sont adressés. Plus précisément, les objectifs étaient de : situer le Service à la famille dans la démarche de recherche d’aide des jeunes; comprendre ce qui amène un jeune à utiliser le Service à la famille et les activités qui y sont offertes; décrire l’expérience d’utilisation du service; connaître la perception qu’en ont les jeunes; et estimer leur appréciation du service. Pour ce faire, des entrevues semi-dirigées par téléphone ont eu lieu avec neuf jeunes ayant eu un suivi au Service à la famille, au cours desquelles certains thèmes ont été explorés : la recherche d’aide en lien avec la situation parentale, l’expérience d’utilisation des services et des activités du Service à la famille, le portrait de celui-ci, et la satisfaction à son égard. Au moment de l’entrevue, tous les jeunes étaient parents d’au moins un enfant et la majorité d’entre eux avait fait appel au Service à la famille la première fois durant la grossesse pour de l’aide sous diverses formes en rapport à celle-ci. Des besoins de divers ordres ont amené les jeunes à faire appel au Service à la famille. Ceux-ci pouvaient être comblés, mais pas nécessairement toujours, par le biais des rencontres avec les intervenantes du Service à la famille et par la participation aux activités de groupe offertes par la ressource et, par ailleurs, pouvaient concorder avec les objectifs d’intervention explicites du service. Dans l’ensemble, les entrevues suggèrent que les jeunes perçoivent le Service à la famille et, plus précisément, les intervenantes qui y travaillent, d’un œil favorable. Les interviewés formulent en effet une appréciation positive sur un bon nombre d’éléments se rapportant à leur expérience d’utilisation de la ressource. Des jeunes perçoivent néanmoins des limites dans la capacité du Service à la famille à fournir l’aide attendue, notamment des restrictions budgétaires et une surcharge de travail des intervenantes liée à une forte demande de services. Même si les jeunes n’ont pas nécessairement demandé de l’aide de la ressource dans l’optique de prévenir la violence familiale et la négligence, mandat premier du Service à la famille, une bonne part d’entre eux reconnaissent avoir reçu de l’aide utile à cet égard de la part des intervenantes, notamment lorsqu’ils ont rapporté avoir vécu des relations amoureuses teintées de violence conjugale. Ils reconnaissent également différentes façons par le biais desquelles les intervenantes les auraient encouragés à être bien et à prendre soin d’eux-mêmes afin de pouvoir bien s’occuper de leur(s) enfant(s). Tous les jeunes interviewés ont exprimé une satisfaction à l’égard du suivi reçu au Service à la famille et ils ont affirmé qu’ils le recommanderaient à d’autres personnes. L’approche d’intervention préconisée par la ressource est considérée comme un point fort dans la réponse aux besoins des jeunes. Cette approche aurait permis aux jeunes devenus parents d’être aidés en fonction de ce dont ils avaient besoin à un moment précis. L’un des aspects de l’utilisation du service qui gagneraient à être améliorés, aux yeux des jeunes, est l’accessibilité; l’aide dont les interviewés considéraient avoir besoin n’ayant pas toujours été à leur disposition alors qu’ils l’avaient demandée. Devant la perception d’un manque de disponibilité des intervenantes, des jeunes proposent des pistes d’amélioration qui permettraient à l’aide dispensée par le Service à la famille d’être plus accessible aux jeunes quand ils considèrent en avoir besoin. / Event though there has been an increased public and research interest in the street youth phenomenon in the past two decades, some aspects of their lives, one of them being parenthood, have not been yet thoroughly examined and therefore, remain unknown to a certain extent. In order to gain a better understanding of street youth’s needs related to becoming a parent, as well as an understanding of the extent to which a service specifically tailored for such a population manages to satisfy their needs, this study had the purpose of describing and understanding the service utilization experience of the Service à la famille from the Montreal street youth agency Dans la rue. More specifically, the objectives were to: gain an awareness and understanding of the persons and resources street youths who become parents turn to for help, and the significance of the Service à la famille among these resources; understand what brings a youth to the Service à la famille and what makes him or her use the services and activities offered; and finally, describe the perceptions and estimate the level of appreciation of the Service à la famille. Semi-structured phone interviews were conducted with nine youths who had used the Service à la famille and had had a follow-up. During the interview, the following themes were explored: help seeking related to becoming a parent, the utilization experience of the services and activities offered by the Service à la famille, the portrait of the service, and level of satisfaction regarding the service utilization experience. At the time of the interview, all youths were parents of at least one child, and the majority had first sought help at the Service à la famille during pregnancy to satisfy different needs related to becoming a parent. A variety of needs brought the youths to seek help at the Service à la famille. These needs could be satisfied, but not necessarily at all times, through meetings with the staff and participation in group activities offered by the service. At times, their needs corresponded to the explicit intervention goals of the service. In general, the interviews suggest that youths have a positive perception of the Service à la famille, and more precisely, of the staff. The interviewees named a considerable number of elements they appreciated from their service utilization experience. Youths nevertheless perceive limitations in the ability of the Service à la famille to give help, especially budgetary constraints and the staff’s workload related to high demand of services. Even though youths did not necessarily seek help from the service in order to prevent family violence or negligence, which is the mandate of the Service à la famille, much of them acknowledge having received valuable assistance in this regard on the part of the staff, especially when they reported having been in a violent intimate relationship. They also recognize different ways through which the staff encouraged them to feel good and take care of themselves in order to do the same with their child or children. All interviewees were satisfied with the follow-up they received from the Service à la famille and claimed they would recommend the service to others. The intervention approach advocated by the service is considered to be a strong element in responding appropriately to youths’ needs. This approach appears to have allowed youths who became parents to get the help they needed at a specific moment in time. According to youths, an aspect of service utilization which could be improved is access to help; since the help interviewees needed was not always available when they asked for it. Since youths perceive a lack of staff availability, they offer suggestions for improvement that would allow the aid supplied by the service to be more accessible to youths when they seek help.

Analysis of Eye-Tracking Data in Visualization and Data Space

Alam, Sayeed Safayet 12 May 2017 (has links)
Eye-tracking devices can tell us where on the screen a person is looking. Researchers frequently analyze eye-tracking data manually, by examining every frame of a visual stimulus used in an eye-tracking experiment so as to match 2D screen-coordinates provided by the eye-tracker to related objects and content within the stimulus. Such task requires significant manual effort and is not feasible for analyzing data collected from many users, long experimental sessions, and heavily interactive and dynamic visual stimuli. In this dissertation, we present a novel analysis method. We would instrument visualizations that have open source code, and leverage real-time information about the layout of the rendered visual content, to automatically relate gaze-samples to visual objects drawn on the screen. Since such visual objects are shown in a visualization stand for data, the method would allow us to necessarily detect data that users focus on or Data of Interest (DOI). This dissertation has two contributions. First, we demonstrated the feasibility of collecting DOI data for real life visualization in a reliable way which is not self-evident. Second, we formalized the process of collecting and interpreting DOI data and test whether the automated DOI detection can lead to research workflows, and insights not possible with traditional, manual approaches.

Rastreamento do olhar na avaliação de presença em atividades mediadas por vídeo. / Gaze tracking for presence evaluation in video mediated activities.

Fernando Yoiti Obana 01 September 2015 (has links)
A percepção de presença (PP), evolução do conceito de telepresença, pode ser definida como ilusão perceptiva de não mediação e/ou a percepção ilusória da realidade. O método mais utilizado para a avaliação da PP faz uso de questionários aplicados aos sujeitos, após sua participação numa experiência. Além de não fornecer informações em tempo real esse método sofre muitas interferências advindas tanto dos sujeitos submetidos ao experimento como dos avaliadores dos questionários. Os métodos que poderiam ser mais efetivos para a avaliação da PP, em tempo real, fazem uso de sinais fisiológicos que variam independentemente da vontade dos sujeitos, como batimento cardíaco, eletrocardiograma, eletroencefalograma, resistividade e umidade da pele. Os sinais fisiológicos, no entanto, só variam de forma significativa em situações de estresse, inviabilizando sua utilização em atividades normais, sem estresse. Outra forma de avaliar a PP é utilizar sistemas de rastreamento do olhar. Estudados e desenvolvidos desde o século 19, os sistemas de rastreamento do olhar fornecem um mapeamento do movimento dos olhos. Além de indicar para onde os sujeitos estão olhando, podem também monitorar a dilatação da pupila e as piscadas. Atualmente existem sistemas de rastreamento do olhar comerciais de baixo custo, que apesar de terem menos precisão e frequência que os equipamentos de alto custo são mais práticos e possuem software de plataforma aberta. No futuro serão tão comuns e simples de usar como são hoje as câmeras em dispositivos móveis e computadores, o que viabilizará a aplicação das técnicas e métodos aqui propostos em larga escala, principalmente para monitorar a atenção e envolvimento de atividades mediadas por vídeo. É apresentada uma ferramenta que faz uso do rastreamento do olhar para avaliar a percepção de presença em atividades mediadas por vídeo (com estímulos sonoros). Dois experimentos foram realizados para validar as hipóteses da pesquisa e a ferramenta. Um terceiro experimento foi executado para verificar a capacidade da ferramenta em avaliar a percepção de presença em atividades não estressantes mediadas por vídeo. / The presence perception (PP), evolution of the concept of telepresence, could be defined as the perceptual illusion of nonmediation and/or the ilusional perception of reality. The most utilized method for PP evaluation make uses questionnaires applied for the subjects, after your participation in an experience. Besides it does not provide real-time information this method suffers with many interferences in the results that come from the subjects undergoing and form the reviewers of the of the questionnaires. The methods could be more effective for PP evaluation, in real time, make uses of physiologic signals that vary independently of the request of the subjects, e.g. heart rate, electrocardiogram, electroencephalogram, skin resistivity and skin humidity. However, meaningful physiologic signals occurs only in stress situations, unfeasible Its use in normal environments, whit no stress. Another way to evaluate the PP is using eye gaze tracking systems. Studied and developed since the 19th century, eye gaze tracking systems provide an eye movements mapping. Moreover it indicate where the subjects are viewing, these systems can follow up pupil dilatation and blinks. Currently there are commercial gaze tracking systems inexpensive, despite having less precision and frequency that expensive-equipments are more practical and open software platform is available. In the future these technologies will be common and simple to use as today are cameras on mobile devices and computers, which will enable the implementation of the techniques and methods here proposed on a large scale, mainly to monitor the attention and involvement during activities mediated by video. A tool that makes use of gaze tracking to evaluate presence perception in activities video mediated (with sound stimuli) is displayed. Two experiments were conducted to validate the hypotheses of the research and the tool. A third experiment was performed to verify the tool\'s ability to assess presence perception in non-stressful activities video mediated.

Desenvolvimento de um método para avaliação qualitativa e quantitativa de fundos de investimento. / Proposal of a method to evaluate investmente funds in a qualitative and quantitative form.

Marcus Alexandre de Souza Moraes 12 July 2000 (has links)
O ato de investir recursos vem se tornando uma tarefa que exige cada vez mais atenção por parte dos investidores. As alternativas de investimento vêm aumentando, oferecendo aos investidores muitas opções em termos de risco, retorno e liquidez. Uma dessas alternativas é o fundo de investimento, uma indústria cujo patrimônio tem crescido muito ao longo do tempo. Atualmente, há mais de R$ 200 bilhões aplicados nas diversas modalidades de fundos oferecidos pelas instituições administradoras de recursos. Escolher qual fundo investir não é tarefa simples, nem mesmo para grandes investidores. As alternativas são inúmeras e as informações nem sempre estão facilmente disponíveis. Oferecer um método que possibilite avaliar e classificar fundos de investimento é o objetivo maior deste trabalho. Busca-se, aqui, um método que contemple, além de variáveis quantitativas, variáveis qualitativas, bem como aspectos relacionados à instituição administradora do fundo. Para alcançar tal objetivo, desenvolveu-se a pesquisa em duas etapas. Na primeira, foram levantadas e agrupadas, através de pesquisa bibliográfica, as variáveis que poderiam vir a fazer parte do método. A segunda etapa foi dedicada à obtenção da ponderação que cada variável e grupo de variável deveria ter no método. Para tanto, foi realizada uma pesquisa de campo junto a determinados grupos de investidores e consultores. O resultado permite que um avaliador dê notas às variáveis e, seguindo o método, obtenha uma nota final para o fundo de investimento analisado. Por fim, sugere-se um modo de classificação de fundos de investimento que procura ser de fácil entendimento, mesmo para aqueles investidores que não são especialistas em mercado financeiro. / Investing money has becoming a task that demands always more attention by investors. Investment alternatives has been growing, offering investors many options in terms of risk, return and liquidity. One of these alternatives is mutual fund, an industry whose assets have been growing a lot during the last years. Nowadays, there are more than R$ 200 billions invested in mutual funds, offered by asset managers. Choosing a fund to invest is not a simple task, even for main investors. There are many alternatives and information is not easily available. Offering a method that permits evaluate and rate mutual funds is the main purpose of this research. This method includes quantitative and qualitative variables, as well as aspects related to its asset manager. To attain this objective, this research was developed in two steps. Firstly, it was selected variables that could be part of the method, by bibliographic search. Secondly, it was obtained weights for both the variables and their group. This goal was achieved through a questionnaire sent to specific investors and consultants. The final result permits an analyst to give a grade to each variable and, using the method, to obtain a final classification for the analyzed fund. This dissertation suggests also a method for ranking mutual funds which intents to be easily comprehended, even to those investors that are not specialized in investment market.
