Differences in prostate cancer detection between Canadian and Saudi populations

Few studies have addressed racial differences in prostate cancer (PCa) detection between Western and Arabian countries, although PCa has a significantly lower prevalence in Arabic populations compared to Western populations. Therefore, an explanation of this difference is lacking. Serum prostate-specific antigen (PSA) is a valuable marker used to select patients who should undergo prostate biopsies, although the manner in which it is used may require adjustments based on the ethnic population in question. We investigated racial differences in the PCa detection rate between Canadian and Saudi populations. A retrospective analysis was performed of data collected prospectively over 5 consecutive years in urology clinics at the McGill University Health Center (MUHC) and King Saud University Hospital (KSUH). Men who had high (>4'ng/mL) or rising PSA levels and a negative digital rectal examination were eligible. A total of 1403 Canadian and 414 Saudi patients were evaluated for the study; 717 and 158 men, median age 64 and 68 years, were included in the MUHC and KSUH cohorts, respectively, P<0.0001). Median serum PSA, prostate volume, and PSA density values were 6.1'ng/mL, 47.3 g, and 0.12'ng·mL−1·g−1, respectively, for MUHC patients and 5.2'ng/mL, 64.5'g, and 0.08'ng·mL−1·g−1, respectively, for KSUH patients (P<0.0001, t-test followed by one-way ANOVA). In addition, the KSUH group had a significantly lower PCa detection rate among patients younger than 60 years of age and with PSA values <10'ng/mL.

The nature of avidyÄ in Buddhism and VedÄ nta

This thesis deals with the nature of ignorance as it was interpreted in the Upani~adic tradition, specifically in Advaita Vedanta, and in early and Mahayana Buddhism , e specially in the Madhyamika school of Buddhism. The approach i s a historical and comparative one. It examines the early thoughts of both the upanis.a ds and Buddhism abou t avidya (ignorance), shows how the notion was treated by the more speculative and philosphically oriented schools which base d themselves on the e arly works, and sees how their views differ. The thesis will show that the Vedinta tended to treat avidya as a topic for metaphysical s peculation as t he s chool developed, drifting from its initial e xistential concerns, while the Madhyamika remained in contact with the e xistential concerns evident in the first discourses of the Buddha. The word "notion" has been chosen for use in referring t o avidya, even though it may have non-intellectual and emotional connotations, to avoid more popular a lternatives such as "concept" or "idea". In neither the Upani,ads, Advaita Vedanta, or Buddhism is ignorance merely a concept or an idea. Only in a secondary sense, in texts and speech , does it become one. Avidya has more to do with the lived situation in which man finds himself, with the subjectobject separation in which he f eels he exists, than with i i i intel lect ual constr ucts . Western thought has begun to r ealize the same with concerns such as being in modern ontology, and has chosen to speak about i t i n terms of the question of being . Avidya, however, i s not a 'question' . If q ue stions we r e to be put regarding the nature of a vidya , they would be more of t he sort "What is not avidya?", though e ven here l anguage bestows a status t o i t which avidya does not have. In considering a work of the Eastern tradition, we f ace t he danger of imposing Western concepts on it. Granted t hat avidya is customari ly r endered i n English as ignorance, the ways i n which the East and West view i gno rance di f f er. Pedagogically , the European cultures, grounded in the ancient Greek culture, view ignorance as a l ack or an emptiness. A child is i gnorant o f certain t hings and the purpose o f f ormal education , in f act if not in theory, is to fill him with enough knowledge so that he can cope wit h t he complexities and the e xpectations of s ociety. On another level, we feel t hat study and research will l ead t o the discovery o f solutions, which we now lack , for problems now defying solut i on . The East, on the o t her hand, sees avidya in a d i fferent light.Ignorance isn't a lack, but a presence. Religious and philosophical l iterature directs its efforts not towards acquiring something new, but at removing t.he ideas and opinions that individuals have formed about themselves and the world. When that is fully accomplished, say the sages , t hen Wisdom, which has been obscured by those opinions, will present itself. Nothing new has to be learned, t hough we do have t o 'learn' that much. The growing interest in t he West with Eastern religions and philosophies may, in time, influence our theoretical and practical approaches to education and learning, not only in the established educati onal institutions, but in religious , p sychological, and spiritual activities as well. However, the requirements o f this thesis do no t permit a formulation of revolutionary method or a call to action. It focuses instead on the textual arguments which attempt to convince readers that t he world in which they take themselves to exist is not, in essence, real, on the ways i n which the l imitations of language are disclosed, and on the provisional and limited schemes that are built up to help students see through their ignorance. The metaphysic s are provisional because they act only as spurs and guides. Both the Upanisadic and Buddhist traditions that will be dealt with here stress that language constantly fails to encompass the Real. So even terms s uch as 'the Real', 'Absolute', etc., serve only to lead to a transcendent experience . The sections dealing with the Upanisads and Advaita Vedanta show some of the historical evolution of the notion of avidya, how it was dealt with as maya , and the q uestions that arose as t o its locus. With Gau?apada we see the beginnings of a more abstract treatment of the topic, and , the influence of Buddhism. Though Sankhara' S interest was primarily directed towards constructing a philosophy to help others attain mok~a ( l iberation), he too introduced t echnica l t e rminology not found in the works of his predecessors. His work is impressive , but areas of it are incomplete. Numbers of his followers tried to complete the systematic presentation of his insi ghts . Their work focuses on expl anat i ons of adhyasa (superimposition ) , t he locus and object of ignorance , and the means by which Brahman takes itself to be the jiva and the world. The section on early Buddhism examines avidya in the context o f the four truths, together with dubkha (suffering), the r ole it p l ays in t he chain of dependent c ausation , a nd t he p r oblems that arise with t he doctrine of anatman. With t he doct rines of e arly Buddhism as a base, the Madhyamika elaborated questions that the Buddha had said t e nded not t o edi f ication. One of these had to do with own - being or svabhava. Thi s serves a s a centr e around which a discussion o f i gnorance unfolds, both i ndividual and coll ective ignorance. There follows a treatment of the cessation of ignorance as it is discussed within this school . The final secti on tries to present t he similarities and differences i n the natures o f ignorance i n t he two traditions and discusses the factors responsible for t hem . ACKNOWLEDGEMENTS I would like to thank Dr. Sinha for the time spent II and suggestions made on the section dealing with Sankara and the Advait.a Vedanta oommentators, and Dr. Sprung, who supervised, direoted, corrected and encouraged the thesis as a whole, but especially the section on Madhyamika, and the final comparison.

El humor judío femenino argentino contemporáneo en la narrativa de Alicia Steimberg, Silvia Plager y Ana María Shúa

En la creación literaria latinoamericana del siglo XX, la narrativa de los autores judíos ha proseguido un trayecto aparte, casi silencioso, en relación con la escritura canónica del continente. No obstante, hacia los años setenta, surge una producción literaria judía femenina que hoy ha alcanzado un renombre internacional. Esta tesis estudia la peculiaridad literaria del humor judío femenino argentino contemporáneo en torno a la definición de la identidad y rol de género, para comprender cómo se resignifica la hibridez cultural en el texto literario. El humor como catarsis de conflictos problematiza la relación entre lo propio y lo ajeno mediante una puesta en tela de juicio de la realidad para manifestarse como una preocupación, una responsabilidad y un compromiso crítico. A través del análisis de las obras de Alicia Steimberg, Silvia Plager y Ana María Shúa, la investigación reconfigura la vida judía diaspórica y el sentido de ser mujer respecto a la importancia del ámbito culinario en cuanto al influjo de la modernidad argentina en la tradición judía. En este estudio, se analizarán las novelas Músicos y relojeros, Como papas para varenikes y Risas y emociones de la cocina judía donde las diferentes reflexiones de Steimberg, Plager y Shúa en relación con la historia judía elaboran discursos con singulares diferencias en la intención humorística. En la primera parte de la tesis, se hará mención de diversas perspectivas teóricas que destacan las implicaciones psicológicas, sociales y psicoanalíticas respecto al humor en general, el humor de la minoría, el humor femenino y el humor judío. En los tres capítulos subsiguientes, se procederá a una lectura de los textos antes mencionados para interpretar las preocupaciones de nuestro tema frente a los dictámenes que la religión y sociedad desean imponer. Finalmente, la conclusión aborda la evolución de una visión entre humor negro, humor como crítica social y humor como lúdico juego en paralelo con una búsqueda de la identidad híbrida actualizada mediante una crítica de lo tradicional.

Arab Women in Translation : the Dynamics of Representation and the Construction of Alterity

Cette recherche examine la traduction et la réception en France, en Grande Bretagne et aux États-Unis de la littérature contemporaine d’expression arabe écrite par des femmes, afin de répondre à deux questions principales: comment les écrivaines provenant de pays arabes perdent-elles leur agentivité dans les processus de traduction et de réception? Et comment la traduction et la réception de leurs textes contribuent-elles à la construction d’une altérité arabe? Pour y répondre, l’auteure examine trois romans présentant des traits thématiques et formels très différents, à savoir Fawḍā al-Ḥawāss (1997) par Ahlem Mosteghanemi, Innahā Lundun Yā ‘Azīzī (2001) par Hanan al-Shaykh et Banāt al-Riyāḍ (2005) par Rajaa Alsanea. L’analyse, basée sur le modèle à trois dimensions de Norman Fairclough, vise à découvrir comment les écrivaines expriment leur agentivité à travers l’écriture, et quelles images elles projettent d’elles-mêmes et plus généralement des femmes dans leurs sociétés respectives. L’auteure se penche ensuite sur les traductions anglaise et française de chaque roman. Elle examine les déplacements qui s’opèrent principalement sur le plan de la texture et le plan pragma-sémiotique, et interroge en quoi ces déplacements ébranlent l’autorité des écrivaines. Enfin, une étude de la réception de ces traductions en France, en Grande Bretagne et aux États-Unis vient enrichir l’analyse textuelle. À cette étape, les critiques éditoriales et universitaires ainsi que les choix éditoriaux relatifs au paratexte sont scrutés de façon à mettre en lumière les processus décisionnels, les discours et les tropes sous-tendant la mise en marché et la consommation de ces traductions. L’analyse des originaux révèle tout d’abord qu’à travers leurs textes, les auteures sont des agentes actives de changement social. Elles s’insurgent, chacune à sa manière, contre les discours hégémoniques tant locaux qu’occidentaux, et (ré-)imaginent leurs sociétés et leurs nations. Ce faisant, elles se créent leur propre espace discursif dans la sphère publique. Toutefois, la thèse montre que dans la plupart des traductions, les discours dissidents sont neutralisés, l’agentivité et la subjectivité des écrivaines minées au profit d’un discours dominant orientaliste. Ce même discours semble sous-tendre la réception des romans en traduction. Dans ce discours réifiant, l’expression de la différence culturelle est inextricablement imbriquée dans l’expression de la différence sexuelle: la « femme arabe » est la victime d’une religion islamique et d’une culture arabe essentiellement misogynes et arriérées. L’étude suggère, cependant, que ce sont moins les interventions des traductrices que les décisions des éditeurs, le travail de médiation opéré par les critiques, et l’intérêt (ou le désintérêt) des universitaires qui influencent le plus la manière dont ces romans sont mis en marché et reçus dans les nouveaux contextes. L’auteure conclut par rappeler l’importance d’une éthique de la traduction qui transcende toute approche binaire et se fonde sur une lecture éthique des textes qui fait ressortir le lien entre la poétique et la politique. Enfin, elle propose une lecture basée sur la reconnaissance du caractère situé du texte traduit comme du sujet lisant/traduisant.

The hypotensive effect of exercise on IOP : an interaction of physical fitness and parasympathetic efficacy

RÉSUMÉ Suite à une centaine de publications sur la réduction de la PIO post-exercice, il est connu que parmi un grand nombre de programme d'exercices de différentes durées et intensités, les effets hypotenseurs de l'exercice sur la PIO sont atténués chez les sujets en bonne condition physique. Le mécanisme proposé est l'augmentation potentielle de l'efficacité du système parasympathique avec l'activité physique. Le principal objectif de cette thèse est d'identifier les facteurs contribuants à la réduction de la PIO post-exercice et d'élucider les différents mécanismes possibles. L'étude 1, une méta-analyse, a été menée afin de quantifier les contributions relatives de l'intensité et de la durée de l'effet de l'exercice sur la PIO et la mesure dans laquelle ces variables affectent les sujets sédentaires et normalement actifs. La tendance ressortant des résultats est que la diminution de la PIO suite à de l'exercice aérobie est plus élevée chez les sujets sédentaires que les sujets en bonne condition physique. (ES = -4.198 mm Hg et -2.340 mm Hg, respectivement). L'absence d'un contrôle des liquides ingérés avant l'activité physique est à souligné dans cette étude. L'hyperosmolarité (un effet secondaire de la déshydratation) est l'un des mécanismes proposés influant l'effet hypotenseur de l'exercice. L'étude 2 comparait la réduction de la PIO dans deux conditions, soit hypohydraté et hyperhydraté, avant, pendant et après un effort de 90 minutes sur un ergocycle. Après une diminution initiale pour les deux conditions, la PIO revient aux valeurs de départ pour la condition hypohydratée malgré une perte de poids significative et elle augmente pour la condition hyperhydratée (résultat du protocole d'hydratation). Étant donné le niveau élevé de participants en bonne condition physique dans l'étude 2, la troisième étude a été conçue afin de etude la relation entre la PIO et la condition physique. À l'aide d'analyses corrélationnelles il a été possible d'observer la relation entre le test de vo2max et la moyenne des mesures de PIO prises sur un intervalle de huit semaines. Une relation significative n'existait que pour les participants se situant dans la portion supérieure du continuum de la condition physique. Conclusion: Les résultats de la présente étude suggèrent que l'effet hypotenseur de l'exercice sur la PIO est probablement une réponse homéostatique à la dérégulation de l'humeur aqueuse causée par l'initiation de l'exercice et le protocole d'ingestion de fluides pré-exercice.

Studies on Energy Exchange and Upper Ocean Thermat Structure in Arabian Sea and Heat Transport in Northern Indian Ocean

The thesis focused Studies on Energy Exchange and Upper Ocean Thermal Structure in Arabian Sea and Heat Transport in Northern Indian Ocean. The present thesis is an attempt to understand the upper ocean thermal characteristics at selected areas in the western and eastern Arabian Sea in relation to surface energy exchange and dynamics, on a climatological basis. It is also aimed to examine, the relative importance of different processes in the evolution of SST at the western and eastern Arabian Sea. Short-term variations of energy exchange and upper ocean thermal structure are also investigated. Climatological studies of upper ocean thermal structure and surface energy exchange in the western and eastern parts of Arabian Sea bring out the similarities/differences and the causative factors for the observed features. Annual variation of zonally averaged heat advection in north Indian Ocean shows that maximum export of about 100 W/m2 occurs around 15ON during southwest monsoon season. This is due to large negative heat storage caused by intense upwelling in several parts of northern Indian Ocean. By and large, northern Indian Ocean is an area of heat export

Some aspects of history of Indian mathematics in 18th and early 19th century

This thesis is an attempt to throw light on the works of some Indian Mathematicians who wrote in Arabic or persian In the Introductory Chapter on outline of general history of Mathematics during the eighteenth Bnd nineteenth century has been sketched. During that period there were two streams of Mathematical activity. On one side many eminent scholers, who wrote in Sanskrit, .he l d the field as before without being much influenced by other sources. On the other side there were scholars whose writings were based on Arabic and Persian text but who occasionally drew upon other sources also.

Appreciation of humor sense in college students

Appreciation of humor includes several cognitive and social processes. None can say that two communities will laugh at the same jokes and find funny the same humorous content. This study worked differences in humor appreciation of university students and comparisons were made between sex and age of participants. To assess the appreciation of humor was built an instrument with 15 written jokes. This instrument was presented to a total sample of 81 students, divided into 3 groups of different age. Participants had to evaluate two aspects: the playfulness and the difficulty of each stimulus or humorous vignette. The jokes that showed significant differences in jocularity have a particular structure marked for a disqualifying content to men, indicating, as noted the literature, that men have more fun with sexual humor and prefers this kind of jokes as well as content related to aggressive or hostile, while women have more fun with humorous vignettes when the man is the victim and reject more when the victim is a woman. In terms of age and the appreciation of humor, there are differences in the type of situations and social contexts valued in the jokes, involving relationship between situational and social aspects of humor.

A natureza na lineal dos funcionamentos inferenciais: um estudo empírico com base no humor gráfico

Analisa-se se os funcionamentos inferenciais têm uma estrutura própria dos sistemas dinâmicos não lineais, estudados a partir de quatro gráficas humorísticas. Os primeiros resultados com o tratamento estadístico lineal de K-medias projetam a presencia de perfis de diferentes funcionamentos inferenciais em função das diferentes piadas. Os resultados com a técnica da wavelet, proveniente dos sistemas dinâmicos não lineais, mostram patrões dos funcionamentos inferenciais que dão conta de sua natureza multifractal, sem uma sequencialidade fixa e sem uma organização aparente. Isto implica que é necessário revisar a concepção de estádios sequenciais fixos como os que dominam os estudos de desenvolvimento cognitivo.

Caricatura económica en Colombia 1880-2008: la economía con algo de humor

La idea central de este libro gira en torno al uso de la caricatura como una fuente histórica para el análisis económico, además es el legado gráfico de los eventos económicos que a lo largo de más de cien años han sido objeto de atención de caricaturistas y lectores de prensa. Dos motivaciones inspiraron este trabajo: de un lado, el estupendo resultado de utilizar la caricatura económica como fuente de análisis e indagación para el curso de Historia Económica de Colombia en la Universidad del Rosario; y de otro lado, la confirmación de que muchos momentos de la historia económica han sido plasmados por los caricaturistas. Ambos motivos son convincentes respecto a la validez de la caricatura como fuente para el análisis de temas económicos, tanto desde una perspectiva histórica como desde una perspectiva netamente económica.
