HLA-DRB1 alleles in juvenile-onset systemic lupus erythematosus: renal histologic class correlations

Human leukocyte antigens (HLA) DRB1*03 and DRB1*02 have been associated with systemic lupus erythematosus (SLE) in Caucasians and black populations. It has been observed that certain HLA alleles show stronger associations with SLE autoantibodies and clinical subsets, although they have rarely been associated with lupus renal histologic class. In the present study, HLA-DRB1 allele correlations with clinical features, autoantibodies and renal histologic class were analyzed in a cohort of racially mixed Brazilian patients with juvenile-onset SLE. HLA-DRB1 typing was carried out by polymerase chain reaction amplification with sequence-specific primers using genomic DNA from 55 children and adolescents fulfilling at least four of the American College of Rheumatology criteria for SLE. Significance was determined by the chi-square test applied to 2 x 2 tables. The HLA-DRB1*15 allele was most frequent in patients with renal, musculoskeletal, cutaneous, hematologic, cardiac, and neuropsychiatric involvement, as well as in patients positive for anti-dsDNA, anti-Sm, anti-U1-RNP, and anti-SSA/Ro antibodies, although an association between HLA alleles and SLE clinical features and autoantibodies could not be observed. The HLA-DRB1*17, HLA-DRB1*10, HLA-DRB1*15, and HLA-DRB1*07 alleles were significantly higher in patients with renal histologic class I, class IIA, class IIB, and class V, respectively. The present results suggest that the contribution of HLA- DRB1 alleles to juvenile-onset SLE could not be related to clinical or serological subsets of the disease, but it may be related to renal histologic classes, especially class I, class II A, class II B, and class V. The latter correlations have not been observed in literature.

Conflicting Memory in Estonia: How Do Estonian Russian-speakers Understand the Events of 1939-40?

This thesis studies the collective memory of the Russian-speaking minority living in Estonia. The minority is exposed to two national narratives regarding the incorporation of Estonia into the Soviet Union in 1940. According to the Estonian narrative, Estonia was occupied and annexed by the Soviet Union while the Soviet-Russian narrative sees the actions to have been legal and voluntary. This thesis firstly examines thoughts the existence of these two opposing narratives evoke among the Russian-speaking minority and secondly it explores whether the views of the minority compare with the two official yet divergent narratives. The study focuses on the second and third generation minority members. The topic belongs to the field of memory studies. The objective is to understand the views the Russian minority have towards the controversial events of the years 1939-40. To accomplish the objectives set, a web-based survey using open-ended and multiple-choice questions was conducted. The open-ended questions addressed the main research questions while the multiple-choice questions contributed to forming a more comprehensive understanding of the subject in question. In order to interpret the data, qualitative content analysis has been applied. Based on the findings, the Russian-speaking minority respondents’ understanding of the events of 1939-40 could be described as fragmented, inconsistent and including viewpoints that resulted from the merger of different storylines. There is no single cohesive or coherent narrative of the past amongst the minority. In addition to that, their views do not generally comply with the narrative of the Russian Federation as often referred to in literature, even though the minority respondents do not want to see the Soviet involvement as critically as the Estonian narrative does. Many respondents conceive the events of 1939-40 as ambiguous revealing the ability to be tolerant and receptive in their views regarding the past.

Relay protection in active distribution networks

Increasingly growing share of distributed generation in the whole electrical power system’s generating system is currently a worldwide tendency, driven by several factors, encircling mainly difficulties in refinement of megalopolises’ distribution networks and its maintenance; widening environmental concerns adding to both energy efficiency approaches and installation of renewable sources based generation, inherently distributed; increased power quality and reliability needs; progress in IT field, making implementable harmonization of needs and interests of different-energy-type generators and consumers. At this stage, the volume, formed by system-interconnected distributed generation facilities, have reached the level of causing broad impact toward system operation under emergency and post-emergency conditions in several EU countries, thus previously implementable approach of their preliminary tripping in case of a fault, preventing generating equipment damage and disoperation of relay protection and automation, is not applicable any more. Adding to the preceding, withstand capability and transient electromechanical stability of generating technologies, interconnecting in proximity of load nodes, enhanced significantly since the moment Low Voltage Ride-Through regulations, followed by techniques, were introduced in Grid Codes. Both aspects leads to relay protection and auto-reclosing operation in presence of distributed generation generally connected after grid planning and construction phases. This paper proposes solutions to the emerging need to ensure correct operation of the equipment in question with least possible grid refinements, distinctively for every type of distributed generation technology achieved its technical maturity to date and network’s protection. New generating technologies are equivalented from the perspective of representation in calculation of initial steady-state short-circuit current used to dimension current-sensing relay protection, and widely adopted short-circuit calculation practices, as IEC 60909 and VDE 0102. The phenomenon of unintentional islanding, influencing auto-reclosing, is addressed, and protection schemes used to eliminate an sustained island are listed and characterized by reliability and implementation related factors, whereas also forming a crucial aspect of realization of the proposed protection operation relieving measures.

Globalization of pharmaceutical R&D. Pharmaceutical R&D governance forms in People's Republic of China

Yrityksen selviytyminen ja menestyminen ovat riippuvaisia sen kyvystä innovoida, luoda tietoa ja hyödyntää tietämystä ja keksintöjä (Dunk ja Kilgore 2001). Yrityksen menestyminen erityisesti korkean teknologian alalla on siten suoraan riippuvainen sen T&T:stä, johon tehdyt investoinnit tuovat merkittäviä taloudellisia etuja yritykselle uusien tuotteiden, palveluiden ja prosessien muodossa (McEvily ja Chakravarthy 1999). Teknologinen etumatka ja sen tuotteistaminen innovatiivisiksi tarjoamiksi mahdollistaa monopolististen etujen saavuttamisen yrityksen kansainvälisessä kilpailussa (Lall 1977). Tämä kaltainen kilpailuetu voidaan saavuttaa yrityksen kyvyllä yhdistää maantieteellisesti hajautettu T&T:nsä tehokkaaksi verkostoksi (Porter 1986). Boehen (2008) mukaan T&T:n globalisoitumista voidaan johtaa eri hallintömuodoilla: T&T:n kansainvälistymisellä, T&T:n ulkomaille sijoittamisella ja T&T ulkomaille ulkoistamisella. T&T:n globalisoituminen on osa 2000-luvun taloudellista muutosta, ja sille on esitetty useita vaikuttavia tekijöitä, kuten kustannuserot, työvoimaresurssit, erityisosaamiskeskukset, paikallinen teknologia osaaminen ja kohdemarkkinoiden potentiaali (bardhan 2006; Norwood, ym. 2006; von Zedtwitz ja Gassmann 2002). Tutkimuksen on osoitettu eroavan tuotekehityksestä ja eri tekijöiden on osoitettu vaikuttavan niihin (von Zedtwitz ja Gassmann 2002; Leifer ja Triscari 1987). Samoin T&T on osoitettu olevan jatkumo perustavanlaatuisesta soveltavaan ja lääkekehityksen muodostavan vastaavan T&T jatkumon (Lall 1980; Iansiti 1993), jonka yksittäiset osat vaikuttavat sen hallintomuotoon. Tutkimus esittää eri tekijöitä voivan hyödyntää hallintomuodosta riippuen. Tätä tutkimusta varten tutkija haastatteli lääketeollisuuden johtajia Kiinassa vahvistaakseen tai hylätäkseen eri tekijöitä ja niiden suhdetta lääketeollisen T&T:n hallintomuotoihin. Markkinoiden todettiin olevan ensisijainen tekijä mutta myös kustannuserojen, insentiivien, työvoimaresurssien ja erityisosaamiskeskusten merkitys T&T:n globalisoitumiseen vaikuttavina tekijöinä vahvistettiin yhdessä perusvaatimusten ja riskitekijöiden kanssa. Tutkimuksessa vahvistetaan myös lääketeollisen T&T-jatkumon vaikutus ja esitetään viitekehys hallintomuodoille.

Globalization of pharmaceutical R&D Pharmaceutical R&D governance forms in People's Republic of China

Firm's survival and success, which are dependent on its ability to innovate, to create knowledge and to capitalize on inventions and know-how, is in essence directly linked to its R&D process (Dunk and Kilgore 2001). Especially in technology driven industries, such as the pharmaceuticals, there are significant positive returns to R&D investments through introduction of new or improved products and services (McEvily and Chakravarthy 1999). Technological lead and its transformation to innovative products as fruits of corporate R&D can be seen as monopolistic advantage that helps enterprises to compete in today’s market (Lall 1977). This competitive advantage can be derived from corporation's ability to integrate its activities across geographic locations (Porter 1986). According to Boehe (2008) globalization of R&D can executed with different governance forms: R&D internationalization, R&D offshoring or R&D offshore outsourcing. Globalization of R&D is intervened with the changes in global economy of the 21st century. Some studies argue for its influencing factors to be access to vast skilled labor pools and centers of excellence (Bardhan 2006). Other studies indicate the R&D cost differentials between countries to be the major expected benefit (Norwood et al. 2006). Von Zedtwitz and Gassmann (2002) presented benefits as divided to accessing markets and customers or to accessing local science and technology. This study proposes that based on governance form distinct factor derived benefits can be capitalized. To corroborate or refute factors and their relations on R&D globalization governance forms, an empirical study based on expert interviews of pharmaceutical directors was conducted in the People's Republic of China. The market was found to be the major influencing factor. Local requirements and adaptation were corroborated as factors connected with markets. Furthermore, influencing factors, such as labour, centers of excellence, cost, financial incentives were corroborated together with conditional and risk factors. Furthermore this research argues that the globalization of pharmaceutical R&D is dependent on the financial, scientific and operational requirements of the drug discovery stage. And thus establishes the influence of drug discovery's stages continuum on pharmaceutical R&D globalization. Finally, a R&D globalization governance form decision framework is proposed based on the frameworks presented in literature and author's corroborated empirical findings.

The new woman, femininity and modernity in Margery Allingham's detective novels of the 1930s /

This thesis examines Death of a Ghost (1934), Flowers for the Judge (1935), Dancers in Mourning (1937), and The Fashion in Shrouds (1938), a group of detective novels by Margery Allingham that are differentiated from her other work by their generic hybridity. The thesis argues that the hybrid nature of this group of Campion novels enabled a highly skilled and insightful writer such as Allingham to negotiate the contradictory notions about the place of women that characterized the 1930s, and that in dOing so, she revealed the potential of one of the most popular and accessible genres, the detective novel of manners, to engage its readers in a serious cultural dialogue. The thesis also suggests that there is a connection between Allingham's exploration of modernity and femininity within these four novels and her personal circumstances. This argument is predicated upon the assumption that during the interwar period in England several social and cultural attitudes converged to challenge long-held beliefs about gender roles and class structure; that the real impact of this convergence was felt during the 1930s by the generation that had come of age in the previous decade-Margery Allingham's generation; and that that generation's ambivalence and confusion were reflected in the popular fiction of the decade. These attitudes were those of twentieth-century modernity--contradiction, discontinuity, fragmentation, contingency-and in the context of this study they are incorporated in a literary hybrid. Allingham uses this combination of the classical detective story and the novel of manners to examine the notion of femininity by juxtaposing the narrative of a longstanding patriarchal and hierarchical culture, embodied in the image of the Angel in the House, with that of the relatively recent rights and freedoms represented by the New Woman of the late nineteenth-century. Pierre Bourdieu's theory of social difference forms the theoretical foundation of the thesis's argument that through these conflicting narratives, as well as through the lives of her female characters, Allingham questioned the Hsocial myth" of the time, a prevailing view that, since the First World War, attitudes toward the appropriate role and sphere of women had changed.

Monstrum : the vampire in the detective story /

My approach to the vampire detective highlights its connections to the private detective's story and reveals the monstrous investigators' debt to early feminist forms of detection -specifically in their reformation of the' other' and of traditional forms of power and authority. Seen in this light the movement of horror's imaginary 'other' into the rational world of detection can be seen as not an abrupt breach of detection's realist conventions, but an almost seamless transition into symbolic spaces that point to the detective's primary function -- to make sense of the senseless. It is in this light that I explore the monster that is a detective as a symbol that is also a sense-maker, and a quintessential postmodern figure. I argue that the distinctions between monsters and 'others', and between popular narratives and postmodern religion have faded, culminating in a character that can not only model 'otherness' as an exemplary condition, but also provide strategies for modeling the form of active postmodern subjectivity that postmodern theorist Jim Collins' (1989) conceives of as heretical activity.

Will the "fight" ever end? : a critical reading of the metaphors and discourses that construct HIV/AIDS in an African context

In this thesis, I critically examine the discourses that inform how we conceptualise HIV/AIDS in Sub-Saharan Africa as they are produced in a sample of Canadian news articles, two nonfiction texts - Stephanie Nolen's 28 Stories of AIDS in Africa and Jonathan Morgan and the Bambanani Women's Group's Long Life ... Positive HIV Stories - as well as two literary texts - John Le Carre's popular fiction novel The Constant Gardener and an anthology of stories and poems from Southern Africa titled Nobody Ever Said AIDS, compiled and edited by Nobantu Rasebotsa, Meg Samuelson and Kylie Thomas. Paying particular attention to the role of metaphor in discursive formation, I have found that military metaphors, usually used in conjunction with biomedical discourses, continue to dominate what is said about HIV/AIDS. However, the use of military metaphors to conceptualise HIV/AIDS contributes to stigma and limits the effectiveness of responses to the pandemic. I argue that accessing alternative metaphors and discourses, such as biopsychosocial discourse, can lead to a more layered - and more beneficial - conceptualisation of HIV/AIDS, encouraging a more active response to the pandemic.

Relationship between photoperiod, plasma concentration of ionic calcium and the histology of the prolactin-secreting cells of the rostral pars distalis of the pituitary gland, the corpuscles of stannius and the ultimobranchial gland in the goldfish, Carassius auratus L. /

The relationship between photoperiod, plasma concentration of ionic calcium and the histology of the prolactin-secreting cells of the rostral pars distalis of the pituitary gland, the Corpuscles of Stannius and the Ultimobranchial gland were investigated. Neither the plasma concentration of ionic calcium nor histologically apparent prolactin cell activity could be correlated with photoperiod. Some evidence of a photoperiodic effect on both the Corpuscles of Stannius and the Ultimobranchial gland was obtained. The expected reciprocal relationship between the activity of these glands was not obvious at the histological level . Quantitative and qualitative analysis at the light microscope level revealed, however, that the hormone prolactin-secreting eta cells of the rostral pars distalis and the hypocalcin-secreting cells of the Corpuscles of Stannius may be arranged in a lamellar pattern comprized of synchronous bands of cells in like-phase of a secretory cycle consisting of four stages - synthesis, storage, release and reorganization. Such synchronized cell cycles in these glands have not heretofore been described in literature. It is suggested that the maintenance of at least 255? of the cells in any one phase of the cycle ensures a supply of the required hormone at all times.

Where's Albania? : staking out the politics of the real and reality in documentary cinema

This thesis, entitled, "Where's Albania? Staking Out the Politics of the Real and Reality in Documentary Cinema," charts the documentary tradition's path from its first incarnations, as filmed travelogue or ethnographic study, for example, right through to its development as a form acting as an objective observer, reflexive commentator, and finally, as a postmodern hybrid. This thesis begins by locating the documentary tradition's origins in realism. Foregrounding documentary cinema as a realist style is important in that it is a contention that spans this entire study. After working through the numerous modes of documentary as outlined by Bill Nichols, I suggest the documentary is often best understood as a hybrid form drawing on numerous modes and conventions. This argument permits my study to make a shift into postmodern theory, wherein I examine postmodernism's relationship to the documentary both as being influenced by it, but also as subsequently forcing documentary cinema to look back at itself and reevaluate the claims it has made in the past, and how postmodernism has drawn these claims to the surface of debate. My thesis concludes with a study of the mockumentary. This analysis confirms the link between postmodernism and documentary, but perhaps more importantly, this analysis investigates postmodemism's critique of the image and representation in general, two elements historically linked to documentary cinema's success as "truth teller."

Gender and Genre in 21st Century Visions of Sherlock Holmes

Sherlock Holmes has been one of the most-adapted characters in literature since his first appearance in A Study in Scarlet in Beeton's Christmas Annual in 1887. Each new adaptation must offer innovations that bring freshness and contemporary appeal to time-worn stories and concepts or risk irrelevancy; analyzing these changes closely sheds light on shifts in societal constructs. Taking this as a starting point, this thesis examines Sherlock and Elementary from a perspective of feminism and queer theory via methods of discourse and genre analyses, with texts ranging from 1931 to the present as objects of comparison. The research illuminates constructions of masculinity as they have changed over time, particularly the movement from an orderly, stable, rational construction of hegemonic masculinity to one that is chaotic, often violent, and anti-heroic in at least some aspects while still being invested in the status quo.

Modèle informatique du coapprentissage des ganglions de la base et du cortex : l'apprentissage par renforcement et le développement de représentations

Tout au long de la vie, le cerveau développe des représentations de son environnement permettant à l’individu d’en tirer meilleur profit. Comment ces représentations se développent-elles pendant la quête de récompenses demeure un mystère. Il est raisonnable de penser que le cortex est le siège de ces représentations et que les ganglions de la base jouent un rôle important dans la maximisation des récompenses. En particulier, les neurones dopaminergiques semblent coder un signal d’erreur de prédiction de récompense. Cette thèse étudie le problème en construisant, à l’aide de l’apprentissage machine, un modèle informatique intégrant de nombreuses évidences neurologiques. Après une introduction au cadre mathématique et à quelques algorithmes de l’apprentissage machine, un survol de l’apprentissage en psychologie et en neuroscience et une revue des modèles de l’apprentissage dans les ganglions de la base, la thèse comporte trois articles. Le premier montre qu’il est possible d’apprendre à maximiser ses récompenses tout en développant de meilleures représentations des entrées. Le second article porte sur l'important problème toujours non résolu de la représentation du temps. Il démontre qu’une représentation du temps peut être acquise automatiquement dans un réseau de neurones artificiels faisant office de mémoire de travail. La représentation développée par le modèle ressemble beaucoup à l’activité de neurones corticaux dans des tâches similaires. De plus, le modèle montre que l’utilisation du signal d’erreur de récompense peut accélérer la construction de ces représentations temporelles. Finalement, il montre qu’une telle représentation acquise automatiquement dans le cortex peut fournir l’information nécessaire aux ganglions de la base pour expliquer le signal dopaminergique. Enfin, le troisième article évalue le pouvoir explicatif et prédictif du modèle sur différentes situations comme la présence ou l’absence d’un stimulus (conditionnement classique ou de trace) pendant l’attente de la récompense. En plus de faire des prédictions très intéressantes en lien avec la littérature sur les intervalles de temps, l’article révèle certaines lacunes du modèle qui devront être améliorées. Bref, cette thèse étend les modèles actuels de l’apprentissage des ganglions de la base et du système dopaminergique au développement concurrent de représentations temporelles dans le cortex et aux interactions de ces deux structures.

D'objet de risée à symbole de l'Amérique : la télévision à travers le cinéma américain (1970 à 1999)

Cette analyse dresse le portrait des différentes représentations de la télévision à travers le cinéma américain de 1970 à 1999. Ce travail porte sur un corpus de quatorze films et s’intéresse à quatre dimensions de la télévision : l’appareil électrique, le téléspectateur, le contenu et l’univers professionnel. Les hypothèses soulevées sont que la télévision est majoritairement présentée de façon négative, que les représentations s’inscrivent dans un contexte culturel précis et qu’il y a un consensus entre les écrits universitaires et les cinéastes au sujet de l’écran cathodique. Bien que certaines critiques soient récurrentes d’une décennie à l’autre, il y a une évolution des représentations. Dans les années 1970, la télévision est un objet de risée. Son contenu est caricaturé et les professionnels qui travaillent pour la télévision sont personnifiés comme des êtres incompétents. Dans les années 1980, le petit écran est montré comme un objet dangereux. Sa très grande popularité en ferait un puissant diffuseur idéologique qui transforme tout en spectacle même la mort. Cette même popularité servira de prétexte aux cinéastes des années 1990 pour utiliser la télévision comme symbole de l’Amérique. Le portrait est peu flatteur : une Amérique corrompue, violente et en manque d’idéaux. Cette analyse montre également qu’au fil des décennies, les mêmes idées circulent entre cinéastes et penseurs américains. Enfin, cette attitude par rapport à la télévision est d’ailleurs symptomatique d’un mépris de l’élite intellectuel envers l’art populaire.
