Les effets du débat public dans la nouvelle ville de Montréal : regard sur le plan d'urbanisme et sa mise en oeuvre

Débat public, participation, délibération, autant de termes utilisés pour parler de normes et de dispositifs qui participeraient au nouvel « impératif délibératif » (Blondiaux et Sintomer 2002). Ce mémoire présente une analyse du débat public sur le plan d'urbanisme de Montréal avec un schéma d'analyse inspiré de celui de Simard et Fourniau (2007). Notre discussion du processus de débat porte non seulement sur la phase formelle des audiences publiques, mais aussi sur les étapes de concertation en amont et sur divers processus plus ou moins publicisés en aval. Ceci permet une réflexion d'ordre procédural plus riche qui considère la diversité des dispositifs dans une perspective de complémentarité. Pour chercher des effets du débat public sur le plan d'urbanisme, nous adoptons le parti de la congruence (Offner 1993), ce qui nous amène à une analyse de l'interaction entre des dynamiques contextuelles et des mobilisations des participants au débat. Certaines de ces congruences concordent avec des modifications au plan d'urbanisme. Notre étude propose aussi des implications du contexte particulier de la nouvelle ville de Montréal (avec la création des arrondissements) sur le contenu du débat public, sur certaines de ses manifestations procédurales ainsi que sur sa portée. Notre dernier chapitre montre que la dynamique du débat public en aval, dans la phase de mise en oeuvre du plan d'urbanisme, se déploie beaucoup plus dans les débats sur les grands projets que sur les mécanismes prévus à cette fin, qui comportent des embûches de par leur faible publicité et le caractère technique du processus réglementaire. Dans l'ensemble, notre étude met en lumière l'importance du contexte : autant le processus de débat que ses effets s'inscrivent dans des dynamiques contextuelles.In this master thesis, the mechanisms of public debate used to discuss the urban master plan of Montreal are analysed with a framework inspired by Simard and Fourniau (2007), which contains a serie of deliberative criterion. Public debate is used as a terminology to include diverse possible mechanisms and norms of debate and of public participation. Our discussion covers not only the formal phase of the debate (in the public hearings) but also the informal forums. We conclude that this allows for a richer procedural analysis based on a perspective of complementarity between diverse mechanisms of public debate. In the search for effects of the public debate on the urban master plan, we found a number of cases where contextual dynamics interacted with the demands of participants. These « congruences » (Offner 1993) concurred with the evolution of the planning document. This master thesis also presents interesting findings related to constraints on public debate brought about by the particular political and institutional context of Montreal. The coordination between the scale of the central city and the newly constituted boroughs had implications on the content of the debate, on procedural components as well as on its impact in the plan and the implementation phase. This suggests that studies of public debate and of public participation events should consider as an important dimension the contextual dynamics

Mobile Self-Efficacy in a Canadian Nursing Education Program

The purpose of this study was to assess the self-efficacy of nursing faculty and students related to their potential use of mobile technology and to ask what are the implications for their teaching and learning in practice education contexts. We used a cross-sectional survey design involving students and faculty in two nursing education programs in a Western Canadian college. 121 faculty members and students completed the survey in January, 2011. Results showed a high level of ownership and use of mobile devices among our respondents. Their median mobile self-efficacy score was 75 on a scale of 100, indicating that they are highly confident in their use of mobile technologies and prepared to engage in mobile learning

Mobile Self Efficacy in Canadian Nursing Education Programs

The purpose of this study was to assess the self-efficacy of nursing faculty and students related to their potential use of mobile technology and to ask what are the implications for their teaching and learning in practice education contexts. We used a cross-sectional survey design involving students and faculty in three separate nursing education programs in Western Canada. Fifty-six faculty members and students completed the survey in March, 2010. Results showed a high level of ownership and use of mobile devices among our respondents. Their overall average mobile self-efficacy score was 72.11 on a scale of 100, indicating that they are highly confident in their use of mobile technologies and prepared to engage in mobile learning

Using Self-Efficacy to Assess the Readiness of Nursing Educators and Students for Mobile Learning

The purpose of this study was to assess the self-efficacy of nursing faculty and students related to their potential use of mobile technology and to ask what implications this technology has for their teaching and learning in practice education contexts. We used a cross-sectional survey design involving students and faculty in two nursing education programs in a western Canadian college. In January, 2011, 121 faculty members and students completed the survey. Results showed a high level of ownership and use of mobile devices among our respondents. The median mobile self-efficacy score was 75 on a scale of 100, indicating that both faculty and students were highly confident in their use of mobile technologies and prepared to engage in mobile learning

Mobile Learning in Nursing Practice Education: Applying Koole's FRAME Model

We report here on an exploratory formative evaluation of a project to integrate mobile learning into a Western Canadian college nursing program. Third-year students used Hewlett Packard iPAQ mobile devices for five weeks in a practice education course in April—May, 2007. Koole's (2009) Framework for the Rational Analysis of Mobile Education (FRAME) model provided our definition of mobile learning and was used to organize our presentation of the results of the study. Participants reported positively on the usability of the mobile devices, finding them easy to learn, readily portable, and the screen size sufficient for mobile specific programs. However, they had difficulty with the wireless connectivity and, despite an initial orientation, did not have time to fully learn the devices in the context of a busy course. As a result, it is not clear if students can effectively use the social technology provided by such devices or if mobile learning can support interaction between instructors and learners in this context. The use of mobile devices in nursing practice education is feasible, but further investigation is needed on the use of m-learning for communication and interactive purposes

Using Mobile Learning to Enhance the Quality of Nursing Practice Education

In this chapter, we first review the research literature pertaining to the use of mobile devices in nursing education and assess the potential of mobile learning (m-learning) for nursing practice education experiences in rural higher education settings. While there are a number of definitions of m-learning, we adopted Koole’s (2005) FRAME model, which describes it as a process resulting from the convergence of mobile technologies, human learning capacities, and social interaction, and use it as a framework to assess this literature. Second, we report on the results of one-on-one trials conducted during the first stage of a two stage, exploratory evaluation study of a project to integrate mobile learning into the Bachelor of Science Nursing curriculum in a Western Canadian college program. Fourth year Nursing students and instructors used Hewlett Packard iPAQ PDAs for a two week period around campus and the local community. The iPAQs provided both WiFi and GPRS wireless capability and were loaded with selected software, including MS Office Mobile, nursing decision-making and drug reference programs. Our participants reported on a variety of benefits and barriers to the use of these devices in nursing practice education

Evaluation of an epigenetic assay for predicting repeat prostate biopsy outcome in African American men

OBJECTIVE: To evaluate an epigenetic assay performed on tissue from negative prostate biopsies in a group of African American (AA) men undergoing repeat biopsy, and to compare accuracy for predicting repeat biopsy outcome to prior studies conducted in predominantly Caucasian populations. MATERIALS AND METHODS: The study population consisted of 211 AA men from 7 urology centers across the United States; all of whom were undergoing 12-core transrectal ultrasound-guided repeat biopsy within 30 months from a negative index biopsy. All biopsy cores from the negative index biopsy were profiled for the epigenetic biomarkers GSTP1, APC, and RASSF1 using ConfirmMDx for Prostate Cancer (MDxHealth, Irvine, CA). RESULTS: Upon repeat biopsy, 130 of 211 subjects (62%) had no prostate cancer (PCa) detected and 81 of 211 (38%) were diagnosed with PCa. Of the subjects with PCa, 54 (67%) were diagnosed with Gleason score (GS) = 7 disease. For detection of PCa at repeat biopsy, ConfirmMDx sensitivity was 74.1% and specificity was 60.0%, equivalent to prior studies (P = .235 and .697, respectively). For detection of GS >= 7 PCa, sensitivity was 78% and specificity was 53%. The negative predictive values for detection of all PCa and GS >= 7 PCa were 78.8% and 94.2%, respectively. CONCLUSION: In this group of AA men, we successfully validated an epigenetic assay to assess the need for repeat biopsy. Results were consistent with previous studies from predominantly Caucasian populations. Therefore, the ConfirmMDx assay is a useful tool for risk stratification of AA men who had an initial negative biopsy

A conformational variant of p53 (U-p53AZ) as blood-based biomarker for the prediction of the onset of symptomatic Alzheimer\u27s disease

BACKGROUND: Ongoing research seeks to identify blood-based biomarkers able to predict onset and progression of Alzheimer\u27s disease (AD). OBJECTIVE: The unfolded conformational variant of p53 (U-p53AZ), previously observed in AD individuals, was evaluated in plasma samples from individuals participating in the Australian Imaging, Biomarkers and Lifestyle (AIBL) cohort for diagnostic and prognostic assessment, validated on a neuropsychological-based diagnosis, over the course of six years. DESIGN: Retrospective Longitudinal Prognostic biomarker study. SETTING: Single-center study based on the AIBL cohort. PARTICIPANTS: 482 participants of the AIBL cohort, aged 60-85 years, without uncontrolled diabetes, vascular disease, severe depression or psychiatric illnesses. MEASUREMENTS: The AlzoSure® Predict test, consisting of immunoprecipitation (IP) followed by liquid chromatography (LC) tandem mass spectrometry (MS/MS), was performed to quantify the AZ 284® peptide as readout of U-p53AZ and compared with an independent neuropsychological diagnosis. The amyloid load via amyloid β-positron emission tomography (Aβ-PET) and supporting clinical information were included where possible. RESULTS: U-p53AZ diagnostic and prognostic performance was assessed in both time-independent and time-dependent (36, 72 and 90 months following initial sampling) analyses. Prognostic performance of Aβ-PET and survival analyses with different risk factors (gender, Aβ-PET and APOE ε4 allele status) were also performed. U-p53AZ differentiated neuropsychologically graded AD from non-AD samples, and its detection at intermediate/high levels precisely identified present and future symptomatic AD. In both time-independent and time-dependent prognostic analyses U-p53AZ achieved area under the curve (AUC) \u3e98%, significantly higher than Aβ-PET AUCs (between 84% and 93%, P respectively \u3c0.0001 and \u3c0.001). As single factor, U-p53AZ could clearly determine the risk of AD neuropsychological diagnosis over time (low versus intermediate/high U-p53AZ hazard ratio=2.99). Proportional hazards regression analysis identified U-p53AZ levels as a major independent predictor of AD onset. CONCLUSIONS: These findings support use of U-p53AZ as blood-based biomarker predicting whether individuals would reach neuropsychologically-defined AD within six years prior to AD diagnosis. Integration of U-p53AZ in screening processes could support refined participant stratification for interventional studies

PubMeth: a cancer methylation database combining text-mining and expert annotation

Epigenetics, and more specifically DNA methylation is a fast evolving research area. In almost every cancer type, each month new publications confirm the differentiated regulation of specific genes due to methylation and mention the discovery of novel methylation markers. Therefore, it would be extremely useful to have an annotated, reviewed, sorted and summarized overview of all available data. PubMeth is a cancer methylation database that includes genes that are reported to be methylated in various cancer types. A query can be based either on genes (to check in which cancer types the genes are reported as being methylated) or on cancer types (which genes are reported to be methylated in the cancer (sub) types of interest). The database is freely accessible at http://www.pubmeth.org

Study protocol for THINK : a multinational open-label phase I study to assess the safety and clinical activity of multiple administrations of NKR-2 in patients with different metastatic tumour types

Introduction: NKR-2 are autologous T cells genetically modified to express a chimeric antigen receptor (CAR) comprising a fusion of the natural killer group 2D (NKG2D) receptor with the CD3 zeta signalling domain, which associates with the adaptor molecule DNAX-activating protein of 10 kDa (DAP10) to provide co-stimulatory signal upon ligand binding. NKG2D binds eight different ligands expressed on the cell surface of many tumour cells and which are normally absent on non-neoplastic cells. In preclinical studies, NKR-2 demonstrated long-term antitumour activity towards a breadth of tumour indications, with maximum efficacy observed after multiple NKR-2 administrations. Importantly, NKR-2 targeted tumour cells and tumour neovasculature and the local tumour immunosuppressive microenvironment and this mechanism of action of NKR-2 was established in the absence of preconditioning. Methods and analysis: This open-label phase I study will assess the safety and clinical activity of NKR-2 treatment administered three times, with a 2-week interval between each administration in different tumour types. The study will contain two consecutive segments: a dose escalation phase followed by an expansion phase. The dose escalation study involves two arms, one in solid tumours (five specific indications) and one in haematological tumours (two specific indications) and will include three dose levels in each arm: 3x10(8), 1x10(9) and 3x10(9) NKR-2 per injection. On the identification of the recommended dose in the first segment, based on dose-limiting toxicity occurrences, the study will expand to seven different cohorts examining the seven different tumour types separately. Clinical responses will be determined according to standard Response Evaluation Criteria In Solid Tumors (RECIST) criteria for solid tumours or international working group response criteria in haematological tumours. Ethics approval and dissemination: Ethical approval has been obtained at all sites. Written informed consent will be taken from all participants. The results of this study will be disseminated through presentation at international scientific conferences and reported in peer-reviewed scientific journals
