description: With the increasing success of hip joint replacements, the average age of patients has decreased, patients have become more active and their expectations of the implant durability have risen. Thus, pre-clinical endurance tests on hip implants require defining realistic in vivo loads from younger and more active patients. These loads require simplifications to be applicable for simulator tests and numerical analyses. Here, the contact forces in the joint were measured with instrumented hip implants in ten subjects during nine of the most physically demanding and frequent activities of daily living. Typical levels and directions of average and high joint loads were extracted from the intra- and inter-individually widely varying individual data. These data can also be used to analyse bone remodelling at the implant-bone interface, evaluate tissue straining in finite element studies or validate analytical loading predictions, among other uses. The current ISO standards for endurance tests of implant stems and necks are based on historic analytical data from the 1970s. Comparisons of these test forces with in vivo loads unveiled that their unidirectional orientations deviate from the time-dependent in vivo directions during walking and most other activities. The ISO force for testing the stem is substantially too low while the ISO force for the neck better matches typical in vivo magnitudes. Because the magnitudes and orientations of peak forces substantially vary among the activities, load scenarios that reflect a collection of time-dependent high forces should be applied rather than using unidirectional forces. Based on data from ten patients, proposals for the most demanding activities, the time courses of the contact forces and the required cycle numbers for testing are given here. Friction moments in the joint were measured in addition to the contact forces. The moment data were also standardized and can be applied to wear tests of the implant. It was shown that friction only very slightly influences the stresses in the implant neck and shaft.

description: Deuterium-tritium inertial confinement fusion implosion experiments on the National Ignition Facility have demonstrated yields ranging from 0.8 to 7×1014, and record fuel areal densities of 0.7 to 1.3 g/cm2. These implosions use hohlraums irradiated with shaped laser pulses of 1.5-1.9 MJ energy. The laser peak power and duration at peak power were varied, as were the capsule ablator dopant concentrations and shell thicknesses. We quantify the level of hydrodynamic instability mix of the ablator into the hot spot from the measured elevated absolute x-ray emission of the hot spot. We observe that DT neutron yield and ion temperature decrease abruptly as the hot spot mix mass increases above several hundred ng. The comparison with radiation-hydrodynamic modeling indicates that low mode asymmetries and increased ablator surface perturbations may be responsible for the current performance.

description: The application of a non-minimum-phase digital filterbank as graphic equalizer is investigated. The filterbank effected a timbral modification of some musical signals even though the magnitude response was unity. For this reason, the filterbank was rejected as a candidate for a high-fidelity graphic equalizer. A new type of equalizing filter is introduced in this work. This filter has the property that its log-magnitude frequency response is approximately linear in the gain term. This filter is used as a building block for an analog and digital parametric equalizer whose frequency response can be adjusted automatically for the use of loudspeaker equalization.

description: Radiation-driven, low-adiabat, cryogenic DT layered plastic capsule implosions were carried out on the National Ignition Facility (NIF) to study the sensitivity of performance to peak power and drive duration. An implosion with extended drive and at reduced peak power of 350 TW achieved the highest compression with fuel areal density of ∼1.3±0.1 g/cm2, representing a significant step from previously measured ∼1.0 g/cm2 toward a goal of 1.5 g/cm2. Future experiments will focus on understanding and mitigating hydrodynamic instabilities and mix, and improving symmetry required to reach the threshold for thermonuclear ignition on NIF.

description: Pluripotent cells can be subdivided into two distinct states, the naïve and the primed state, the latter being further advanced on the path of differentiation. There are substantial differences in the regulation of pluripotency between human and mouse, and in humans only stem cells that resemble the primed state in mouse are readily available. Reprogramming of human stem cells into a more naïve-like state is an important research focus. Here, we developed a pipeline to reanalyze transcriptomics data sets that describe both states, naïve and primed pluripotency, in human and mouse. The pipeline consists of identifying regulated start-ups/shut-downs in terms of molecular interactions, followed by functional annotation of the genes involved and aggregation of results across conditions, yielding sets of mechanisms that are consistently regulated in transitions towards similar states of pluripotency. Our results suggest that one published protocol for naïve human cells gave rise to human cells that indeed share putative mechanisms with the prototypical naïve mouse pluripotent cells, such as DNA damage response and histone acetylation. However, cellular response and differentiation-related mechanisms are similar between the naïve human state and the primed mouse state, so the naïve human state did not fully reflect the naïve mouse state.

description: Corporate entrepreneurship (CE) involves strategic entrepreneurship (SE) and corporate venturing (CV). This research centers on three topics, exploring SE and CV, via three related papers. The first paper focuses on exploring SE through a systematic literature review, thereby evaluating its dynamic micro-foundations and the interlinked exploration and exploitation processes while unveiling future research avenues. The second paper examines how CV affects knowledge acquisition (KA) and performance, and investigates how this relationship is influenced by the external environment and transformational leadership. The third paper examines how SE relates to employee retention and recruitment, and tests how competition and corporate reputation moderate the aforementioned relationship. Novel data of small and medium sized enterprises (SMEs) in the United Kingdom and Germany are used to address the research questions. The study reveals that CV positively influences KA and performance. Furthermore, the study shows that technological turbulence and transformational leadership positively moderate the relationship between CV and performance. The study also confirms a strong effect of SE on both employee retention and recruitment. It further affirms that the relationship between SE and employee retention is strengthened when firms operate in competitively intensive environments. In all, this thesis contributes to extant research by developing and validating direct reflective measurement scales for CV and SE thereby also paving the way to further explore the domain of CE.

description: The success of personal communication networks will depend on their ability to accommodate the diverse traffic which will be generated from the numerous and diverse future multimedia applications and services. Towards this end, multimedia Medium access control (MAC) algorithms capable of accommodating this integrated traffic will play a major role. In this thesis, novel MAC protocols are proposed and their ability to efficiently utilize the available bandwidth is evaluated. The proposed multimedia MAC protocols are based on random access algorithms and reservation policies using TDM and CDMA technologies. The MAC protocols also support multiple-priority mechanisms: an essential feature in communication systems supporting integrated services with diverse Quality of Service (QoS) requirements. One of the major characteristics of the priority mechanism is its simplicity of implementation. This adds to the practical value of the proposed MAC protocols. The TDMA and the CDMA versions of the protocols are evaluated for voice and data traffic and compared to other MACs proposed in the literature. The CDMA version of the protocol is also investigated for data, voice and video with multi-slot reservation for video. Network configurations servicing CBR (variable quality) and VBR (constant quality) video users are evaluated. The results verified the superiority of the proposed protocol: high school utilization and ability to service effectively high volumes of integrated traffic. The new MACs are found to be stable, robust and easy to implement multimedia services in personal communication networks. The simplicity and high performance level of the proposed MACs makes it valuable for supporting integrated traffic wireless applications.
Problem-solving characteristics of relative novices and experts within an intermediate range of expertise in linear kinematics.

description: Within the context of this study, expertise is used to describe the range of skills (a continuum) which lies between those of novice and expert. Although some of these expert-novice differences have been identified, what is less understood is how an individual becomes an expert: the transition from novice to expert. As the study tests a specific hypothesis and seeks information related to a specific objective, it has both confirmatory and exploratory components. The independent variables were context, level of expertise and Problem Type and the dependent variables were solution time and solution patterns. There were two categories of context (familiar and unfamiliar), two levels of expertise (novice and expert) and two Problem Types (simultaneous and successive movement). Solution time was analyzed within a confirmatory framework and solution patterns within an exploratory framework. An information-processing approach to problem-solving was used. From 108 university students an inventory of contexts was compiled to produce familiar and unfamiliar isomorphic problems. The level of expertise of a second group of 57 subjects was based on educational background and produced Concept Map. From this process, two intermediate groups of subjects were identified as relative experts or novices. Each subject was presented with eight isomorphic problems, four in familiar and four in unfamiliar contexts, were presented to each subject. The subjects were presented with one of two Problem Types reflecting Simultaneous or Successive movements as defined by Piaget. The problem solutions were recorded using the technique developed by Ericsson and Simon (1984), were divided into 5-second intervals, and then evaluated using a Coding Grid developed for this study. Thus, the data submitted for analysis was based on a total of 224 problems. While the subjects in this study did represent two distinct levels of expertise, they did not evidence those characteristics associated with the extremes of the expert-novice continuum. There were no significant differences between experts and novices in their problem solution times, but the relative expert subjects did demonstrate some of the 'traditional' expert traits. In particular, experts evidenced an improved ability to recognize key information and, thereby, improve the accuracy of their performance. The more expert problem solver also used more conceptual, as distinct from computational, types of strategy. Overall, while there were no significant differences in solution time, many expert-novice distinctions arose when examining the processes whereby these solutions were achieved. In particular, while the experts tended to show an analytical approach, the novices were more speculative.

description: In this qualitative multiple-case study, three teachers’ understanding of holistic education philosophy was explored through their enacted instructional practices in mathematics classrooms in a holistic school in India. Drawing upon the ethnographic methodology, the data collected include interviews and conversations, classroom observations, and field notes. Teachers’ understanding of the holistic education philosophy was primarily explored through semi-structured interviews and informal conversations, while their instructional practices were largely understood through classroom observations. The data were analyzed in two ways, the first round of data analysis happened simultaneous to data collection through a contemplative practice of Astachal which was a ritual at Sahyadri, and the second round of data analysis was conducted through formal coding and categorizing methods post the data collection period. The data are presented in the form of rich information and thick descriptions of teachers’ understanding and actions, which are vital in understanding both the preparation of teachers within a holistic learning environment as well as the enactment of teaching practices in mathematics classrooms within the context of a holistic school. Drawing from the literature on alternative schools and holistic education, a set of holistic instructional practices was compiled, which was used to guide the data analysis as well as present the findings of the study. The implications including a framework to design holistic instruction are discussed along with the directions for future research as well as the limitations of the study.

Performance evaluation of mechanically attached roofing systems

Subjects: subject: Engineering, Civil.

description: Roofing system is an integral part of a building envelope. Keeping the roofs in place against high wind events is a challenging task for architects and roof designers. There are two stages in the design process: first, a comprehensive understanding of the wind induced loads on the roof system and, second, an accurate estimation of the system response to the induced wind loads. The present study contributes to an ongoing research project at the National Research Council Canada in the evaluation of Mechanically Attached Roofing Systems (MAS) for wind uplift design. Accomplishments are grouped in two tasks. Task 1, applied finite element methods to investigate whether an analytical method can be used to predict fastener loads based upon uplift pressures and chamber geometry. Task 2, developed an experimental procedure to quantify the air leakage rate and identified its impact on the wind uplift resistance. The aspect ratio of the testing chamber plays a critical role in the evaluation of roofing system response. By applying finite element modeling the table size effect was investigated and the numerical results were benchmarked with experimental data. The validated model was further used to identify the required table width. It was found that an increase in the table width beyond required table width did not significantly change the system response. The required table width depends mainly on two system parameters, namely, fastener row spacing and fastener spacing. Based on the parametric investigation generalized correction factor curves were developed such that the roofing designer can apply these factors irrespective of the investigated table width. In MAS, the fluttering or "billowing" action of the membrane draws air in to system, thereby affecting system's wind uplift performance. There is no standard specification or test method available to quantify the air leakage rate. By designing an experimental setup, systems with and without barriers were investigated. Data clearly indicate that systems without barrier had a high rate of air leakage, compared to systems with barrier. With the quantification of air leakage, its impact on the wind uplift resistance was also evaluated under a dynamic wind environment. Improvement in wind uplift resistance was evident for systems with barriers.

description: Background Transcatheter left atrial appendage occlusion (LAAO) is a promising therapy for stroke prophylaxis in non-valvular atrial fibrillation (NVAF) but its cost-effectiveness remains understudied. This study evaluated the cost- effectiveness of LAAO for stroke prophylaxis in NVAF. Methods A Markov decision analytic model was used to compare the cost-effectiveness of LAAO with 7 pharmacological strategies: aspirin alone, clopidogrel plus aspirin, warfarin, dabigatran 110 mg, dabigatran 150 mg, apixaban, and rivaroxaban. Outcome measures included quality-adjusted life years (QALYs), lifetime costs and incremental cost-effectiveness ratios (ICERs). Base-case data were derived from ACTIVE, RE-LY, ARISTOTLE, ROCKET-AF, PROTECT-AF and PREVAIL trials. One- way sensitivity analysis varied by CHADS2 score, HAS-BLED score, time horizons, and LAAO costs; and probabilistic sensitivity analysis using 10,000 Monte Carlo simulations was conducted to assess parameter uncertainty. Results LAAO was considered cost-effective compared with aspirin, clopidogrel plus aspirin, and warfarin, with ICER of US$5,115, $2,447, and $6,298 per QALY gained, respectively. LAAO was dominant (i.e. less costly but more effective) compared to other strategies. Sensitivity analysis demonstrated favorable ICERs of LAAO against other strategies in varied CHADS2 score, HAS-BLED score, time horizons (5 to 15 years) and LAAO costs. LAAO was cost-effective in 86.24 % of 10,000 simulations using a threshold of US$50,000/QALY. Conclusions Transcatheter LAAO is cost-effective for prevention of stroke in NVAF compared with 7 pharmacological strategies. Condensed abstract The transcatheter left atrial appendage occlusion (LAAO) is considered cost-effective against the standard 7 oral pharmacological strategies including acetylsalicylic acid (ASA) alone, clopidogrel plus ASA, warfarin, dabigatran 110 mg, dabigatran 150 mg, apixaban, and rivaroxaban for stroke prophylaxis in non-valvular atrial fibrillation management.
Learning from communication data: Language in electronic business negotiations

description: When people communicate, language is one of the means of reaching the goal of communication. Negotiations by electronic means is an example of communication where language is the principal deal-making tool. Negotiators use language to persuade, threaten and query, aiming to get the largest piece of the pie, to reach a compromise or to find prospective partners. Here is a sample from electronic negotiations, with the original spelling, punctuation and capitalization: Seller. Dear BuTTerFLy Thanks for your offer. I see there are still some things that have to be thought about. We both come along with payment upon delivery. I could imagine a price of $3.98 and delivery 45 days, but unfortunately with the returns i cant make you any other offers. I hope you quite like this offer. Im sure an agreement will be found. Im looking forward to your respond, daisy. Buyer. To my dearest friend daisy... Thank you for your quick respond, I quite like your second offer. However I'll be more than happy if the price goes down to 3.71$ and the delivery would be within 30 days (about the payment and the return I don't have any problems with them). I'll really appreciate it if you accept the offer I just made, but if you don't, I'm sure somehow we'll come up with an agreement. yours faithfully BuTTerFLy!!!!! We apply statistical modelling and build a semantic lexicon to find the characteristics of e-negotiation data which make it unique. We find language patterns that signal of negotiator roles and success or failure of negotiations. Research in human communication shows that it is very difficult to find the characteristics of unsuccessful activities and communication corresponding to them. The interesting and promising result of this dissertation comes in the form of identifying two sets of features that characterize successful and unsuccessful communication respectively. We use these sets to represent negotiations and then classify the negotiation outcomes. The results show the advantage of the proposed feature selection approach compared with the popular statistical selection. We apply our research to the largest available collection of electronic negotiations and, when appropriate, to data of face-to-face negotiations. In the dissertation we employ methods developed for Corpus Linguistics, Natural Language Processing and Machine Learning. We investigate the ability of the methods to model and classify the data. Throughout the dissertation we examine hypotheses on language, learning and the process of electronic negotiations.
Bank markup behaviour and the elasticity of the supply of funds in Canada: An empirical analysis.
Creators: name: Tissaaratchy, Piyanjali M.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Economics, Finance.

description: This dissertation studies the nature of the elasticity of the supply of funds through the analysis of concepts as presented by post Keynesian horizontalists and post Keynesian non-horizontalists. These two competing views are outlined, and pertinent issues are isolated. Empirical analysis is performed using data for the Canadian economy in order to assess the validity of both positions. In order to distinguish empirically between horizontalists and non-horizontalists, the variability of the commercial bank markup is tested, as well as any evidence of the presence of financial fragility. A markup that varies with changes in gross domestic product would indicate that the determination of the interest rate was not purely a supply-side phenomenon, and would violate the horizontalist position. Any evidence of the presence of financial fragility resulting from increased firm indebtedness would also indicate that constraints on monetary creation exist, as consistent with non-horizontalist views. The econometric tests attempted in this dissertation address both these issues using Canadian data for the 1980 to 1995 period. The results of the empirical tests conducted do not provide any evidence to support an upward sloping money supply function. (Abstract shortened by UMI.)

description: Background Recently, a growing number of Item-Response Theory (IRT) models has been published, which allow estimation of a common latent variable from data derived by different Patient Reported Outcomes (PROs). When using data from different PROs, direct estimation of the latent variable has some advantages over the use of sum score conversion tables. It requires substantial proficiency in the field of psychometrics to fit such models using contemporary IRT software. We developed a web application (http://www.common- metrics.org), which allows estimation of latent variable scores more easily using IRT models calibrating different measures on instrument independent scales. Results Currently, the application allows estimation using six different IRT models for Depression, Anxiety, and Physical Function. Based on published item parameters, users of the application can directly estimate latent trait estimates using expected a posteriori (EAP) for sum scores as well as for specific response patterns, Bayes modal (MAP), Weighted likelihood estimation (WLE) and Maximum likelihood (ML) methods and under three different prior distributions. The obtained estimates can be downloaded and analyzed using standard statistical software. Conclusions This application enhances the usability of IRT modeling for researchers by allowing comparison of the latent trait estimates over different PROs, such as the Patient Health Questionnaire Depression (PHQ-9) and Anxiety (GAD-7) scales, the Center of Epidemiologic Studies Depression Scale (CES-D), the Beck Depression Inventory (BDI), PROMIS Anxiety and Depression Short Forms and others. Advantages of this approach include comparability of data derived with different measures and tolerance against missing values. The validity of the underlying models needs to be investigated in the future.

description: I explore the historical antecedents of contextual constructionism--the theoretical structure employed in this essay--which is rooted in the development of symbolic interactionism and labelling theory. I also devote attention to an overview of selected interactionist, labelling, conflict, and contextual constructionist accounts of the 'illicit drug' issue. I illustrate how early interactionist and more recent contextual constructionist studies have demonstrated that claims-making against 'illicit drugs' are typically based on soft or non-existent evidence, and that such claims-makers have engaged in moral crusades against 'illicit drugs', not to address 'objective' harmful conditions, but rather for bureaucratic interests and to promote certain moral positions. I examine the methodological approach used by Goldhagen (1996) in his provocative account of the causes underlying the nature and magnitude of the Holocaust. This quasi-constructionist analysis clearly exemplifies the power of symbolic communication in the social construction of definitions of problematic conditions and the development of intervention strategies.

Despite big differences in the way they approached their task and in the conclusions they reached, both reviews recommended the creation of new regulatory authorities backed by statute. Although for different reasons they also attached much significance to the idea of independence. Both reviews might have delivered better results if they had recognised that independence matters only as one of several factors affecting the broader and more important question of whether a regulator's decisions are regarded as legitimate.
Petrogenesis of post-spreading seamount volcanism in the South China Sea

description: The South China Sea basin was created by a short-lived rifting event from ~32-16 Ma, and since then, there has been small volumes of continued magmatism in the South China Sea (‘post-spreading’ volcanism) and adjacent onshore areas that have been tentatively linked to the Hainan mantle plume. As the magmatism in the South China Sea is submarine, there is a limited amount of samples available, from dredges and drilling. For this project, I used samples from four separate dredging cruises (Vema36 1979, Sonne23 1982, Estase 1984, Nanhai 1985) that had limited existing compositional data available. I analyzed the samples for high-precision trace elements by solution ICP-MS, and used these data (with particular focus on the rare earth elements) to learn more about how melts are formed in the region: how much melting takes place and the depth in the mantle, and how this links to variation in the thickness of the lithosphere. In conjunction with these new analyses, I compiled a compositional database of analyses of ocean crust and ‘post-spreading’ magmatism from the South China Sea and onshore Cenozoic volcanism in China, Vietnam, and Thailand.
description: Using Dy/Yb as a gauge of depth of melting, and La/Sm as a gauge of the degree of melting, the ‘post-spreading’ volcanism samples all have high La/Sm and Dy/Yb relative to the South China Sea ocean crust, consistent with smaller degrees of melting at greater mean depths. Spatial and temporal trends in La/Sm are somewhat scattered, but with a broad increase from ~16 Ma to ~8 Ma indicating a general decrease in the extent of melting. In contrast, Dy/Yb shows a broad trend of increasing values over time, consistent with progressively deeper melting that can be explained by the gradual increase in oceanic lithosphere over time due to cooling. Higher Dy/Yb values are also found in samples from the rifted margins, consistent with deeper melting beneath thicker rifted continental lithosphere.
Understanding ecclesiastical laws: Canon 17 in light of contemporary hermeneutics.

description: Ecclesiastical law as an objectivation of the Church's understanding of its own spiritual and social life, puts itself into the great tradition of interpreting the expressions of human life which is hermeneutics. As the canonical tradition of interpretation of ecclesiastical laws brings to light the conflict between common sense and theory, hermeneutics stresses the dialogical nature of understanding, its dynamic character, its historical dimension as operating within and mediating with the different traditions, and its actuality expressed in application to the present. Some particular results of this research point to the traditional notion of the proper meaning of the words (propria verborum significatio) as demanding the consideration of a larger context which entails various disciplines of the Church's science. Similarly, the reflection on recourse to the mind of the legislator tends to disprove the voluntarist conception of the interpretation of the meaning of laws which equates the search for the will of the legislator with the ultimate goal of the interpretative activity in the canonical realm. The findings on the ground of the particular branches of hermeneutics entitle the A. to formulate an outline of a theory of understanding which incorporates some pertinent results of hermeneutical reflection, valid for the endeavor of interpretation of canon law. The analysis of the process of understanding permits one to maintain that the mutual interdependence and interactiveness of cognitional operations create a kind of hermeneutical circle. This allows the interpreter to discover the meaning of the whole by applying each particular insight to enrich, qualify, and correct the already achieved understanding of a legal text. Moreover, the analysis of the notion of a legal norm together with some ontological presuppositions lead to the concept of an evolutive interpretation. This evolutive character constitutes a particular feature of the endeavor to interpret the laws and guarantees keeping in touch with the requirements of answering the problems of understanding the significance of the law for the People of God in every time and place. To sum up, hermeneutics creates the awareness that the meaning of a legal text is not simply offered to a passive subject-interpreter in any routine procedure, but presents itself as a dynamic and creative reality requiring constant interaction between various subjective and objective, textual and extra-textual factors.

description: This exploratory project investigates how current academic library practice related to FAIR principles are applied to research outputs such as software and other NTROs(e.g. film, creative writing, website design), including areas where there are opportunities to improve or expand practice related to the application of the FAIR principles to NTROs. The project also explores how the CARE principles should be applied to these outputs. The project situates the role of the academic library in the broader Open Research landscape and explores how the library's work relates to the work of other bodies both within and beyond the researcher's institution. The project also produces a framework that provides guidance for CAUL Member institutions about how to increase the proportion of NTROs by Australian university researchers that are appropriately described, archived, preserved and made accessible.

Outputs from this project include:

Final Outputs Report - FAIR and Open Non-Traditional Research Outputs.pdf- the main report from this project

Implementation of a power adaptive fuzzy control system for end milling processes.
Creators: name: Rahmati, Seyed Saeed.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Engineering, Mechanical.

description: This thesis reports a fuzzy control system designed for power control of end milling processes. As compared to most of the existing end milling control systems, the proposed fuzzy control system has the following advantages: (a) multi-parameter adjustment; (b) insensitive to changes in work piece geometry, cutter immersion rate, and workpiece material; (c) cost-efficient and easy to implement; and (d) mathematically modeling-free. The proposed fuzzy controller is a two-input two-output system with simple triangular membership functions for both feedrate and spindle speed. The system also features a scaling factor adjustment mechanism used to tune the gain coefficients. The system is first examined by simulation using Simulink and Matlab fuzzy logic toolbox and then verified by various experiments on a CNC milling machine. The experiments carried out include: (i) steel cutting with different change patterns (gradual linear change, gradual curved change, and abrupt step change) in depth of cut; (ii) steel cutting with full and partial immersion rates; (iii) steel cutting with variable immersion rate; and (iv) aluminum cutting with step change in depth of cut. The experimental results show that as compared to single parameter (feedrate) adjustment the material removal rate can be improved by up to 25% when both feedrate and spindle speed are adjusted. It is also shown that the proposed system is stable and displays very good transient performance under all of our experimental conditions, indicating sound robustness. The use of power sensor has significantly reduced investment cost and avoided tedious setups. The simplicity in design and implementation of the system has been demonstrated in our development process.
Voz de fe, voz de razon: Lectura critica del "Evangelio Americano"

description: Dans cette etude, on aborde l'essai en tant qu'espace dialogique ou convergent des contradictions et des tensions discursives antagoniques envers l'ordre etabli. Dans cette perspective, nous presentons une analyse critique-discursive de l'essai intitule El Evangelio Americano, dernier ouvrage de l'essayiste et penseur politique chilien Francisco Bilbao Barquin (1823-1865). En prenant comme point de depart la theorie du dialogisme de Mikhail Bakhtine et le lien qu'on y etablit entre signe linguistique et ideologie, nous proposons ici une approche de l'oeuvre de Bilbao dans laquelle on met en evidence les processus d'ideologisation qui marquent les relations de reaction, d' incorporation et de transformation de textes et de discours. Notre these comprend trois chapitres. Nous explorons d'abord, au premier chapitre, les notions theoriques qui permettent d'etablir le lien entre essai, discours et ideologie. Ensuite, au deuxieme chapitre, nous examinons le contexte historique et social qui sous-tend la production de l'oeuvre. Enfin, au troisieme chapitre, nous presentons une analyse des processus discursifs de reproduction du systeme des idees sociales, politiques et religieuses que partagent l'enonciateur textuel et le(s) interlocuteur(s). En bref, la lecture critique d'El Evangelio Americano vise a demontrer la relation multiforme que l'enonciateur entretient avec divers discours de son epoque: dans certains cas, il adhere a ces discours; dans d'autres, il en differe totalement ou partiellement. Nous soulignons aussi la pertinence des outils theoriques utilises en analysant brievement les possibilites et les avantages qu'ils offrent.

description: This research considered and observed the ways in which volunteer docents at The University of Iowa Stanley Museum of Art engaged with elementary-age students attending a needs-based after-school program field trip. In order to collect information, data was gathered by observation and field notes during two docent-led tours. The data analysis demonstrated the strengths and areas of growth for docent training and the potential for incorporating the voices of the visitor and community into the art museum. From a pedagogical perspective, the research emphasizes the need to consider the changing nature of audiences and collaboration amongst those outside the art museum field.
