"...Mr. J. W. Anderson...produced in 1797 a little work under the title of 'The Common Prayer, as read by the late Mr. Garrick.' In re-editing this work, I have endeavoured to increase its usefulness by the addition of such notes as would give more exactness to Mr. Garrick's remarks." -- Editor's Preface, p. xii.

This paper surveys hostile reactions to claims that the I I September attacks were understandable in terms of the actions of the west towards poor parts of the world and the rich countries' own public commitments to democracy and affluence at home. The paper argues that domestic resentment is likely to continue to foment because concerted institution-building commensurate with the rich countries' material capacities has been neglected. Much responsibility for the global discontent can be attributed to policies advocated by the west and imposed on both rich and poor countries alike by policy-elites within the rich countries. Intellectuals have a role in re-activating the sorts of high-minded state-building and policy-making capacities that preoccupied them in the immediate post-1945 period.

This paper introduces a new technique for optimizing the trading strategy of brokers that autonomously trade in re- tail and wholesale markets. Simultaneous optimization of re- tail and wholesale strategies has been considered by existing studies as intractable. Therefore, each of these strategies is optimized separately and their interdependence is generally ignored, with resulting broker agents not aiming for a glob- ally optimal retail and wholesale strategy. In this paper, we propose a novel formalization, based on a semi-Markov deci- sion process (SMDP), which globally and simultaneously op- timizes retail and wholesale strategies. The SMDP is solved using hierarchical reinforcement learning (HRL) in multi- agent environments. To address the curse of dimensionality, which arises when applying SMDP and HRL to complex de- cision problems, we propose an ecient knowledge transfer approach. This enables the reuse of learned trading skills in order to speed up the learning in new markets, at the same time as making the broker transportable across market envi- ronments. The proposed SMDP-broker has been thoroughly evaluated in two well-established multi-agent simulation en- vironments within the Trading Agent Competition (TAC) community. Analysis of controlled experiments shows that this broker can outperform the top TAC-brokers. More- over, our broker is able to perform well in a wide range of environments by re-using knowledge acquired in previously experienced settings.

Pt catalyst series were prepared on mesoporous SBA-15, SBA-16, KIT-6, true liquidcrystal-templated meso-macroporous SBA-15 and a commercial, low surface area silicasupport. Support structure can be easily fabricated using surfactant templating as a mode ofstringent control on porosity, surface area and internal structure. The impact of varying Pt-support physicochemical properties was systematically studied for the selective transformation of allylic substrates under chemoselective oxidation and hydrogenation regimes, a class of reactions highly applicable to industry. Pt-based heterogeneous catalysts are well-known for their utilisation in the hydrogenation of α,β-unsaturated aldehydes,although the mode of action and lack of systematic studies in the literature fuels continuing debate into the role of Pt nanoparticles and support choice for this area. This project attempts to shed some light on several frequently asked questions in this field. Successful support synthesis and stability after Pt impregnation is confirmed through HRTEM, XRD and N2 porosimetry. Decreasing metal loading promoted dispersion values,regardless of support choice, with surface PtO2 content also showing visible enhancement.Increasing support surface area and mesoporosity exhibited the following trend on Pt dispersion augmentation; low surface area commercial silica < true liquid crystal-templated SBA-15 < SBA-15 < SBA-16 ~ KIT-6. For the selective oxidation of cinnamyl alcohol,increasing PtO2 surface population confers substantial rate enhancements, with turnover frequencies evidencing PtO2 to be the active species .In the Pt-catalysed hydrogenation of cinnamaldehyde, strong support insensitivity was observed towards catalytic activity; as turnover frequencies normalised to Pt metal reveal constant values. However, structure sensitivity to the desired unsaturated alcohol arose,evidencing the requirement of flat, extended Pt (111) facets for C=O hydrogenation. Pt/SBA-15 proved the most selective, reflecting suppressed cinnamyl alcohol hydrogenation, with DRIFTS and in-situ ATR-IR evidencing the key role of support polarity in re-orientation of cinnamaldehyde to favour di-σCO adsorption and C=O versus C=C hydrogenation. High pressures increased activity, whilst a dramatic shift in selectivity from dominant C=C (1 bar)to C=O hydrogenation (10 bar) was also observed, attributed to surface crowding and suppression of di-σCC and η4 di-σCO+πC=C cinnamaldehyde binding modes.

This dissertation examines the discursive practice of Argentine costumbrista texts from a novel perspective. In (re)reading the works of selected prominent writers from the late colonial period to the end of the Nineteenth Century, including those of Alonso Carrió de la Vandera, Emeric Essex Vidal, León Pallière, Lucio Vicente López, Lucio V. Mansilla, and Pastor Obligado we focus on the presence of ekphrastic enunciations with a view toward linking the plastic, painterly dimensions of the prose to parallel representations by artists of the same period. Thus the costumbristas are studied in tandem with the watercolors, oil paintings and lithographic compositions of artists such as Carlos Enrique Pellegrim, César Hipólito Bacle, Raymond Monvoisin and Hipólito Moulin. The resulting comparative study of the two arts---the verbal and the pictorial---illustrates the notion described by W. J. T. Mitchell that a literary text may well "represent a work of visual or graphic art." And thus, it provides us with visual, spatial motifs that enhance its powers of representation. ^ In developing our focus on ekphrastic representations we have followed the theoretic studies of Murray Krieger, Jean H. Hagstrum, James Hefferman, John Hollander, W. J. T. Mitchell, Johann Gottfried Herder, and Wendy Steiner among others, all of whom in various ways take their cue from Horace's Ut pictura poesis and the notion that poetry, that is literary discourse, can be likened to a panting and that in both arts there is a refractive quality that makes literature a spoken vehicle of expression and painting a silent, complementary voice. ^ In studying the literary and plastic discourses comparatively what becomes evident is that they share cultural and ideological concerns that center around the notion of self-definition, national identity, and the relation of the individual to the incipient national community (Benedict Anderson). These concerns are highlighted via the depiction of customs, mores, dress, work habits, professions, and social classes. In late colonial literature and painting and especially in the Nineteenth Century, which constitutes the defining period of Argentine political independence, the confluence of the two disciplinary discourses addresses, and underscores the issues of socio-political empowerment in the new Argentine nation. ^

This article reviews the historical literature on slave self-activity during the US Civil War, taking account of recent developments in historiography. Attempting to move beyond the debate between those who argue for 'slave self-emancipation' and others who emphasize the role of high politics, this article suggests that while slaves played a central role in re-directing the war into an assault on slavery, there were severe constraints on their activity as well. Northern military advances played a critical role in opening up the Confederate South to slave self-assertion.

This thesis focuses on “livsfrågor” (questions of life) a typical Swedish concept introduced in the RE syllabus in the curriculum for compulsory schools in 1969. The study poses three questions: what can qualify as a “livsfråga”, why are they regarded important, and how do they fit into teaching? The main purpose is to study differences of the concept in two materials. Primarily interviews with Teacher educators all over Sweden and, secondly in the R.E. syllabus for compulsory and secondary schools from 1962 until today. Finally, the two materials used, will be brought together, and foci are recognized with the help of a tool for thought. The study is using the concept dialogicity from Bachtin. Syllabus are viewed as compromises in accordance with a German tradition. In the syllabus, “livsfrågor” is one within many different words used with none what so ever stringency. It is not necessarily the most important term, as “livsåskådningsfrågor” (questions within philosophies of life) is often dominating in objectivities. Also “existential questions” etc is used. The relation between the words are never made clear. The syllabus are in one sense monologial as different meanings of the word are not made explicit, and other utterances are not invoked. In the interviews the dialogicity is more obvious. Philosophy is mentioned, eg.. Martin Buber, Viktor Frankl, theology (Paul Thillich), but also literature (Lars Gyllensten) and existentialism in a general sence. Other words are not as frequent – but “livsåskådningsfrågor” are of course mentioned, eg. Faith vs. knowledge. In the last chapter “livsfrågor” is problematized with the help of Andrew Wright and his three metanarrativies within the modern R.E. And the assumption, especially in the syllabus, of “livsfrågor”, as common between cultures and over time is problematized with the help of . feministic theory of knowledge.

This article seeks to exemplify the extent to which oral life history research can enrich existing historiographies of English Religious Education (RE). Findings are reported from interviews undertaken with a sample of key informants involved in designing and/or implementing significant curriculum changes in RE in the 1960s and 1970s. The interviews provided insights into personal narratives and biographies that have been marginal to, or excluded from, the historical record. Thematic analysis of the oral life histories opened a window into the world of RE, specifically in relation to professional identity and practice, curriculum development, and professional organizations, thereby exposing the operational dynamics of RE at an (inter-)personal and organizational level. The findings are framed by a series of methodological reflections. Overall, oral life histories are shown to be capable of revealing that which was previously hidden and which can be confirmed and contrasted with knowledge gleaned from primary documentary sources.

The pre-operative size of breast tumour is the most important factor in determining feasibility of breast conserving surgery in operable breast cancer. Currently there is no consensus on the most accurate modality to measure tumour size. A prospective study of consecutive and unselected symptomatic patients with invasive breast cancer who had primary surgery between January 2006 and December 2007 was conducted. Patients with multi-focal and multi-centric tumours were excluded. The aim of this study was to find the correlation between histological size of invasive breast cancer and pre-operative tumour size as measured by ultrasound. Over this two year period, data for 192 patients was analysed for this study. The mean tumour diameter on ultrasound and histology was 19.5mm and 29mm respectively. The difference between the means in the two modalities was found to be statistically significant (P<0.001).Ultrasound underestimates the true size of breast tumours as determined histologically. Inaccurate tumour size measurements may result in re-operations to achieve adequate margins.

Os fenómenos migratórios têm contribuído para a configuração de uma realidade sociocultural diversa que marca as sociedades do século XXI. Portugal não é exceção, sendo um dos países onde mais aumentou proporcionalmente a imigração legal permanente, fenómeno coexistente com a emigração da sua população. Neste contexto de migrações reconfiguram-se identidades, não apenas para os migrantes mas também para os autóctones, cuja (re)construção balança entre a semelhança e a diferença. Sem esta relação, a identidade fica comprometida, pois ela existe fundamentalmente pelo reconhecimento dos outros. A liberdade cultural e linguística é também uma dimensão do desenvolvimento humano, pelo que tem vindo a ganhar proeminência a promoção da diversidade linguística e cultural, e a consequente educação intercultural, que se assume como espaço privilegiado de reflexão e ação. Defende-se que a verdadeira integração dos imigrantes terá de ser multilingue e não pode ser realizada apagando as suas diferenças, nem obrigando-os a abandonar as suas línguas nativas e culturas. O domínio da Língua Portuguesa é uma das vias mais poderosas para a integração dos estrangeiros a residir em Portugal, tanto como garantia da autonomia individual que faculta o exercício de uma cidadania ativa, como de harmonia social ao nível coletivo. A escola portuguesa, atenta a este facto, vê reconhecida, por parte do Ministério da Educação, a Língua Portuguesa como fator de integração. Todavia, esse reconhecimento contrasta com a indiferença perante as línguas maternas dos alunos estrangeiros, ignorando-se, assim, um importante elemento das suas pertenças identitárias. Neste âmbito, alguns autores afirmam que a escola portuguesa nem sempre tem praticado uma verdadeira educação intercultural, adotando, pelo contrário, parte das características hegemónicas da cultura dominante, o que se traduz, por conseguinte, no esmagamento simbólico (coletivo) das culturas minoritárias. O nosso estudo usa as Representações Sociais como formas de conhecimento prático que permitem a compreensão do mundo e a comunicação, proporcionando coerência às dinâmicas sociais. Procurámos fazer, através delas, uma leitura da valorização da diversidade linguística e cultural na escola, uma vez que as Representações Sociais que se têm do Outro justificam a forma como se interage com ele e imprimem direção às relações intra e intergrupais. A investigação que aqui apresentamos procura dar primazia à “voz” do aluno como fonte de conhecimento, aos fenómenos, a partir das experiências interindividuais e intergrupais, e à forma como as pessoas experienciam e interpretam o mundo social que constroem interativamente. Para esse efeito, recolhemos dados através de entrevistas semidiretivas individuais junto de dez alunos autóctones e dez alunosestrangeiros de uma mesma escola. Complementarmente, realizámos entrevistas aos Encarregados de Educação de oito dos alunos entrevistados, quatro de cada grupo, aos cinco Diretores de Turma desses alunos e ao Diretor da escola. Do ponto de vista metodológico, a presente investigação desenvolveu-se de acordo com uma abordagem de natureza qualitativa, relacionada com um paradigma fenomenológico-interpretativo – os fenómenos humanos e educativos apresentam-se, na sua complexidade, intimamente relacionados e a sua compreensão exige a reconciliação entre a epistemologia e o compromisso ético. Procurando uma leitura global dos resultados obtidos, e à semelhança de alguns estudos, a nossa investigação demonstra que, ao não se promover proativamente uma educação intercultural – designadamente a sua função de crítica cultural e o combate a estereótipos e preconceitos que essencializam as diferenças do Outro culturalmente diverso –, a escola não prepara os alunos para a sociedade contemporânea, culturalmente diversa, dinâmica e com um elevado nível de incerteza, nem para uma abordagem positiva e frontal dos conflitos em toda a sua complexidade. À escola impõem-se ainda muitos desafios relativos às muitas diversidades que acolhe no seu seio, de forma a que todos aqueles que constituem a comunidade escolar – designadamente os alunos, sejam eles estrangeiros ou autóctones – se sintam parte integrante dela, respeitados tanto pelas suas raízes, como pelas múltiplas pertenças dinamicamente em (re)construção, como, ainda, pelos seus projetos de futuro. A informação, por si só, não promove a ação. Revela-se necessária a adoção de estratégias de intervenção que concretizem a informação nas práticas escolares quotidianas, que promovam encontros positivamente significativos, que favoreçam a igualdade social e o reconhecimento das diferenças e, ainda, que previnam atitudes discriminatórias. Para essas estratégias de intervenção serem uma constante no quotidiano das nossas escolas, a didática intercultural deve ser incentivada e operacionalizada, tanto na prática pedagógica como na formação inicial e contínua dos professores.

Nous nous proposons d’esquisser une réflexion comparative axée sur le thème de la mort, à partir de l’analyse de La Peste (1947) d’Albert Camus et As Intermitências da Morte (2005) de José Saramago. Dès lors, ces deux romans présentent au lecteur deux expériences littéraires de la mort, apparemment différentes mais, en réalité, axées sur une même interrogation de l’Homme, celle de la mort. Notre hypothèse de lecture vise donc à analyser comment cette réflexion sur la mort se développe dans les deux romans, à partir de la peste et des intermittences de la mort.

AIM: To investigate the effects of malnutrition and refeeding on the P2X(2) receptor, nitric oxide synthase (NOS), calretinin, calbindin and choline acetyltransferase (ChAT) in neurons of the rat ileum. METHODS: We analyzed the co-localization, numbers and sizes of P2X(2)-expressing neurons in relation to NOS-IR (immunoreactive), calbindin-IR, ChAT-IR, and calretinin-IR neurons of the myenteric and submucosal plexus. The experimental groups consisted of: (1) rats maintained on normal feed throughout pregnancy until 42 d post-parturition (N); (2) rats deprived of protein throughout pregnancy and 42 d post-parturition (D); and (3) rats undernourished for 21 d post-parturition and then given a protein diet from days 22 to 42 (DR). The myenteric and submucosal plexuses were evaluated by double labeling by immunohistochemical methods for P2X(2) receptor, NOS, ChAT, calbindin and calretinin. RESULTS: We found similar P2X(2) receptor immunoreactivity in the cytoplasm and surface membranes of myenteric and submucosal neurons from the N, D and DR groups. Double labeling of the myenteric plexus demonstrated that approximately 100% of NOS-IR, calbindin-IR, calretinin-IR and ChAT-IR neurons in all groups also expressed the P2X(2) receptor. In the submucosal plexus, the calretinin-IR, ChAT-IR and calbindinIR neurons were nearly all immunoreactive for the P2X(2) receptor. In the myenteric plexus, there was a 19% increase in numbers per cm(2) for P2X(2) receptor-IR neurons, 64% for NOS-IR, 84% for calretinin-IR and 26% for ChAT-IR neurons in the D group. The spatial density of calbindin-IR neurons, however, did not differ among the three groups. The submucosal neuronal density increased for calbindin-IR, calretinin-IR and ChAT-IR neurons. The average size of neurons in the myenteric plexus neurons in the D group was less than that in the controls and, in the re-fed rats; there was a 34% reduction in size only for the calretinin-IR neurons. CONCLUSION: This work demonstrates that expression of the P2X(2) receptor is present in inhibitory, intrinsic primary afferent, cholinergic secretomotor and vasomotor neurons. Undernutrition affected P2X(2) receptor expression in the submucosal plexus, and neuronal and size. These changes were rescued in the re-fed rats. (C) 2010 Baishideng. All rights reserved.

Silicon carbide ceramics (SiC) are used in different applications in the engineering area due to the excellent properties, mainly in high temperatures. They are usually obtained by liquid-phase sintering enabling to form volatile products and, consequently, defects. The present work aims at studying the obtention of SiC ceramics by spontaneous infiltration using a eutectic composition of the Al(2)O(3)/Y(2)O(3), AIN/Y(2)O(3), Al(2)O(3)/Sm(2)O(3), AlN/Sm(2)O(3), Al(2)O(3)/RE(2)O(3) and AlN/RE(2)O(3) Systems. RE(2)O(3) is the concentrate of the rare-earth oxide obtained from Xenotime ore. Infiltration tests were carried out in argon atmosphere, graphite crucibles, in several temperatures near the melting point of each system, varying from 2.5 to 60 min. It was observed that Al(2)O(3)/Y(2)O(3), Al(2)O(3)/SM(2)O(3), AlN/SM(2)O(3) and Al(2)O(3)/RE(2)O(3) systems do not infiltrate appropriately and the AlN/Y(2)O(3) and AlN/RE(2)O(3) systems infiltrated spontaneously more than 20 mm; however, the first one presented a higher degree of infiltration, approximately 97%.

This paper reports theoretical and experimental studies of gas-phase fragmentation reactions of four naturally occurring isoflavones. The samples were analyzed in negative ion mode by direct infusion in ESI-QqQ, ESI-QqTOF and ESI-Orbitrap systems. The MS/MS and MS(n) spectra are in agreement with the fragmentation proposals and high-resolution analyses have confirmed the formulae for each ion observed. As expected, compounds with methoxyl aromatic substitution have showed a radical elimination of center dot CH(3) as the main fragmentation pathway. A second radical loss (center dot H) occurs as previously observed for compounds which exhibit a previous homolytic center dot CH(3) cleavage (radical anion) and involves radical resonance to stabilize the anion formed. However, in this study we suggest another mechanism for the formation of the main ions, on the basis of the enthalpies for each species. Compounds without methoxy substituent dissociate at the highest energies and exhibit the deprotonated molecule as the most intense ion. Finally, energy-resolved experiments were carried out to give more details about the gas-phase dissociation reaction of the isoflavones and the results are in agreement with the theoretical approaches.
