The impact of communication disability on quality of life of people with aphasia and their caregivers

Aphasia is a chronic acquired communication disorder that may change people with aphasia (PWA) and their caregivers’ lives for ever. Social and emotional changes are frequently reported by both, although the impact of these changes in quality of life (QOL) needs further research. This study identifies predictors and variables that influence PWA’s and their caregivers’ QOL and social relationships (SR). A cross-sectional descriptive, correlational and comparative study was undertaken with 255 individuals from Portuguese general population (mean age 43 years, range 25-84 years; 148 females, 107 males), 25 PWA (mean age 54 years, range 20-71; 12 females and 13 males), and 25 caregivers (mean age 51 years, range 26-73; 17 females and 8 males). All the participants completed the World Health Quality of Life Bref instrument, the SR domain of the World Health Organization Quality of Life – 100 scale, and the Center for Epidemiologic Studies Depression Scale. Participants with aphasia completed the Lisbon Aphasia Assessment Battery, Barthel Index, Frenchay Activities Index, Communication Disability Profile and the Modified Mini-Mental State which evaluated language disability, aphasia coefficient, activities, participation and cognition. In addition, caregivers completed the Carers’ Assessment of Managing Index to assess coping strategies. PWA and their caregivers are less satisfied with their QOL and SR than Portuguese general population; whereas PWA have the worse QOL and SR. Thus, aphasia seems to impact negatively in their QOL and SR. Emotional status has great importance for QOL and SR among the three groups. PWA’s activities and participation have great impact in both PWA’s and caregivers’ QOL and SR. Additionally, emotional status and participation are the best predictors of PWA’s QOL. Along with these two variables, activities of the PWA are the best predictors of caregivers’ QOL. Participation is the best predictor of PWA’s SR; emotional status and number of cohabitants are best predictors for caregivers’ SR. Aphasia assessment and intervention should take into account all the factors that influence PWA’s and caregivers’ QOL and SR so the central goal of enhancing it can be achieved. These results are important for identifying and planning support needs and are useful in the orientation of the activities carried out by the service providers allowing the adjustment of health programs and policies based on people’s real life needs.

Étude des compétences informatiques et des attitudes du corps professoral face à l'utilisation des technologies de l'information et de la communication (TIC) à l'Institut de Technologie du Cambodge (ITC)

L'utilisation des nouvelles technologies de l'information et de la communication (NTIC) fait l'objet de discussions dans le domaine de l'éducation. La présente recherche a pour objectif principal d'identifier le profil des compétences informatiques et des attitudes du corps professoral d'une haute école de formation technologique du Cambodge au regard de l'utilisation des environnements informatiques dans sa pratique d'enseignement. Cette étude descriptive exploratoire aura comme principale retombée de contribuer au développement de l'intégration des NTIC en pédagogie universitaire au Cambodge. Nous tenterons éventuellement de mettre en lumière les besoins que cette intégration suscite. L'élaboration d'une stratégie de systématisation de l'implantation des NTIC en pédagogie universitaire pourrait être traitée dans une future étude. Le recueil de données a été réalisé à l'aide d'un questionnaire d'enquête ainsi que d'une série d'entrevues réalisées auprès du personnel enseignant de l'Institut de Technologie du Cambodge durant la session d'hiver 2001.

État des conditions qui favorisent l'intégration des technologies de l'information et de la communication en adaptation scolaire au primaire et au secondaire selon les perceptions des enseignantes et des enseignants du Québec

Les recherches menées en éducation permettent de constater que les technologies de l'information et de la communication ont des effets positifs sur plusieurs dimensions de l'élève. Pourtant, dans ce domaine, l'implantation de la micro-informatique s'effectue lentement. Le projet de recherche trace le portrait des conditions qui favorisent l'intégration des TIC en adaptation scolaire et démontre dans quelle mesure elles sont présentes selon les perceptions des enseignants au Québec. Les sujets sont des enseignants en adaptation scolaire à la commission scolaire de Montréal (CSDM). Le questionnaire et l'entrevue semi-structurée ont été utilisés pour la collecte de données. Les résultats de l'enquête sont présentés à partir d'une analyse quantitative et qualitative. Ils démontrent que des efforts ont été déployés pour fournir aux écoles des ressources matérielles et pour développer des attitudes et perceptions positives chez les enseignants. Cependant, les enseignants réclament davantage de formation ainsi qu'un soutien technique et pédagogique continu.

Le journalisme de communication dans la presse écrite québécoise : étude comparée des quotidiens Le Devoir et La Presse

Ce mémoire a pour objectif d'observer les caractéristiques du paradigme du journalisme de communication dans la presse écrite québécoise en comparant 22 articles tirés des rubriques "faits divers", "politique", "international" et "environnement" des quotidiens Le Devoir et La Presse . Pour ce faire, nous présentons d'abord un aperçu de l'état actuel de la presse écrite, en pleine crise identitaire depuis les années 80 à la suite de l'arrivée des nouvelles technologies. Les bouleversements qui en ont découlé ont profondément transformé la manière de traiter l'information journalistique, si bien que les chercheurs Jean Charron et Jean de Bonville parlent d'un changement de paradigme -- du journalisme d'information vers le journalisme de communication. D'autres, comme Thierry Watine, préfèrent qualifier ce phénomène "d'hybridation des genres". En nous basant sur ces théories, nous avons retenu une série de caractéristiques propres au journalisme de communication à repérer au sein de notre corpus. Ainsi, nous dénombrons les caractéristiques du journalisme de communication dans chaque article pour ensuite comparer les résultats du Devoir et de La Presse. Par la suite, nous proposons quelques pistes de réflexion sur la place occupée par le journalisme de communication dans la presse écrite québécoise. En ce qui concerne les résultats généraux, Le Devoir et La Presse présentent des similitudes avec 254 caractéristiques au Devoir et 217 à La Presse. De plus, les deux journaux utilisent les quatre mêmes principales caractéristiques : l'évaluation, l'imputation, le registre familier et les métaphores. Par contre, les résultats du Devoir et de La Presse divergent quand nous les observons à l'échelle des rubriques. Enfin, notre étude démontre que les caractéristiques du journalisme de communication occupent une place prépondérante dans la presse écrite, sans pour autant évacuer complètement les caractéristiques du journalisme d'information.

Communicating culture: strategic communication management of the contemporary art museums in the XXIth century, in Portugal: case studies: Museu Nacional de Arte Contemporânea: Lisboa; Museu de Arte Contemporânea de Serralves, no Porto; Museu de Arte Contemporânea de Elvas

Throughout the year and half of research developed during the times of crisis or economic crisis in Portugal due to the austerity measures, this thesis focuses on the cultural communication and museology in the area of cultural management in Portugal. With an ever growing number of research being developed over the world, this study is unique as it studies managerial diversity and organisational structures of Contemporary Art Museums that exist in Portugal but more importantly how they communicate their organizations within and beyond the Museum walls such as online or other technological media. As the communication management of the museums is one of aspects of culture in which cultural management intends to intervene. The research study that I proposed to analyse has at the forefront the intention to understand how the Contemporary Art Museums in Portugal manage their communication and respective organizations, whether they be a Public-Private/Foundation, State or Council run organizations but also understand if a strategic plan is designed and implemented in times of crisis, to withstand disruptive economic scenarios projected on a daily basis. The following Museums were selected due to the fact of being Contemporary Art Museums but also their respective diverse territorial distribution, one in the city capital of Portugal, Lisbon: MNAC – Museu Nacional de Arte Contemporânea, a stately run organisation; the second, in the north of Portugal: MACS – Museu de Arte Contemporânea de Serralves, a public/private organisation under the Foundation organics and the third Museum in interior central region of Portugal, Alentejo: MACE – Museu de Arte Contemporânea de Elvas, managed by the Elvas City Council.

Chemical communication in the Mozambique tilapia: a role for amino acids

The Mozambique tilapia (Oreochromis mossambicus) is a maternal mouthbrooding cichlid from the southern Africa. The olfactory sensitivity of the species to 20 amino acids was assessed using the electro-olfactogram (EOG). We estimated whether the olfactory potency of the polar fraction of male urine can be explained by the presence of identified amino acids. In addition, filtrate and amino acid mixture of the urine of Nile tilapia were used to estimate their olfactory potency for O.mossambicus. Finally, concentrations of the main amino acids were measured in the urine of males of different social status and the correlations between amino acid concentration and hierarchical status were explored. L-cysteine, L-glutamine and L-threonine were the most potent stimuli at M while L-proline and L-aspartate were the least potent. Four groups of amino acids were identified according to their thresholds of detection and three groups – according to the similarity of their ɣ-factors. The estimated threshold of detection for O.mossambicus mixture was higher than that for the filtrate. On the contrary, the threshold of detection for the mixture of Nile tilapia was lower than that for the filtrate The concentration of L-arginine in the urine was positively correlated with fish dominance index. Both L-arginine and L-glutamic acid concentrations had much greater variability in dominant males (DI˃0.5) than in subordinate males (DI˂0.5). The urinary concentrations of L-phenylalanine had similar variability in dominant and subordinate groups. The Mozambique tilapia has olfactory sensitivity to all twenty amino acids tested. The fish showed more acute sensitivity to conspecific urine filtrate than to the heterospecific. Olfactory potency of O.mossambicus filtrate can be largely but not fully explained by the presence of L-arginine, L-glutamic acid and L-phenylalanine. Larginine and L-glutamic acid may indicate the dominance status of the fish and, possibly, individual identity.

Joint compensation of IQ-imbalance and carrier phase sychronization errors in communication receivers

This work addresses the joint compensation of IQimbalances and carrier phase synchronization errors of zero- IF receivers. The compensation scheme based on blind-source separation which provides simple yet potent means to jointly compensate for these errors independent of modulation format and constellation size used. The low-complexity of the algorithm makes it a suitable option for real-time deployment as well as practical for integration into monolithic receiver designs.

Living and dealing with RF impairments in communication transceivers

This paper provides an overview of the sources and effects of the RF impairments limiting and rendering the performance of the future wireless communication transceivers costly as well as hindering their wide-spread use in commercial products. As transmission bandwidths and carrier frequencies increase effect of these impairments worsen. This paper studies and presents analytical evaluations of the performance degradation due to the RF impairments in terms of bit-error-rate and image rejection ratio. The paper also give highlights of the various aspects of the research carried out in mitigating the effects of these impairments primarily in the digital signal processing domain at the baseband as well as providing low-complexity hardware implementations of such algorithms incorporating a number of power and area saving techniques.

World Cultures in English(es) at the School of Arts and Humanities Library, University of Lisbon: the Communication Platform Architecture and Its Critical Analysis

We will consider the architecture of the communication platform prototype, "World Cultures in English(es)" (WCE), in relation to the interaction among different types of media and audiences. Such an architecture has emphasized the need for an interdisciplinary team of scholars, librarians, and Information Technology experts who have conceived the prototype. This prototype was developed using PHP and MySQL, and is based on the University of Lisbon server. The "World Cultures in English(es)" is an Open Access platform bringing together different types of documents—written, audio, visual, multimedia, and electronic—and aims at educational, cultural, social, and economic inclusiveness, namely in terms of users with special needs. The WCE platform strongly implies social commitment through reliable information and forms of communication adequate to different kinds of audiences. The "World Cultures in English(es)" prototype will be tested by different audiences from different schools and universities, leading to the necessary adjustments.
