Empilhamento pelo método superfície de reflexão comum 2-D com topografia e introdução ao caso 3-D

O método de empilhamento sísmico CRS simula seções sísmicas ZO a partir de dados de cobertura múltipla, independente do macro-modelo de velocidades. Para meios 2-D, a função tempo de trânsito de empilhamento depende de três parâmetros, a saber: do ângulo de emergência do raio de reflexão normal (em relação à normal da superfície) e das curvaturas das frentes de onda relacionadas às ondas hipotéticas, denominadas NIP e Normal. O empilhamento CRS consiste na soma das amplitudes dos traços sísmicos em dados de múltipla cobertura, ao longo da superfície definida pela função tempo de trânsito do empilhamento CRS, que melhor se ajusta aos dados. O resultado do empilhamento CRS é assinalado a pontos de uma malha pré-definida na seção ZO. Como resultado tem-se a simulação de uma seção sísmica ZO. Isto significa que para cada ponto da seção ZO deve-se estimar o trio de parâmetros ótimos que produz a máxima coerência entre os eventos de reflexão sísmica. Nesta Tese apresenta-se fórmulas para o método CRS 2-D e para a velocidade NMO, que consideram a topografia da superfície de medição. O algoritmo é baseado na estratégia de otimização dos parâmetros de fórmula CRS através de um processo em três etapas: 1) Busca dos parâmetros, o ângulo de emergência e a curvatura da onda NIP, aplicando uma otimização global, 2) busca de um parâmetro, a curvatura da onda N, aplicando uma otimização global, e 3) busca de três parâmetros aplicando uma otimização local para refinar os parâmetros estimados nas etapas anteriores. Na primeira e segunda etapas é usado o algoritmo Simulated Annealing (SA) e na terceira etapa é usado o algoritmo Variable Metric (VM). Para o caso de uma superfície de medição com variações topográficas suaves, foi considerada a curvatura desta superfície no algoritmo do método de empilhamento CRS 2-D, com aplicação a dados sintéticos. O resultado foi uma seção ZO simulada, de alta qualidade ao ser comparada com a seção ZO obtida por modelamento direto, com uma alta razão sinal-ruído, além da estimativa do trio de parâmetros da função tempo de trânsito. Foi realizada uma nálise de sensibilidade para a nova função de tempo de trânsito CRS em relação à curvatura da superfície de medição. Os resultados demonstraram que a função tempo de trânsito CRS é mais sensível nos pontos-médios afastados do ponto central e para grandes afastamentos. As expressões da velocidade NMO apresentadas foram aplicadas para estimar as velocidades e as profundidades dos refletores para um modelo 2-D com topografia suave. Para a inversão destas velocidades e profundidades dos refletores, foi considerado o algoritmo de inversão tipo Dix. A velocidade NMO para uma superfície de medição curva, permite estimar muito melhor estas velocidades e profundidades dos refletores, que as velocidades NMO referidas as superfícies planas. Também apresenta-se uma abordagem do empilhamento CRS no caso 3-D. neste caso a função tempo de trânsito depende de oito parâmetros. São abordadas cinco estratégias de busca destes parâmetros. A combinação de duas destas estratégias (estratégias das três aproximações dos tempos de trânsito e a estratégia das configurações e curvaturas arbitrárias) foi aplicada exitosamente no empilhamento CRS 3-D de dados sintéticos e reais.

The effectiveness of interpretive methods in informal educational facilities : an experimental study with reference to marine parks

Interpretation has been used in many tourism sectors as a technique in achieving building hannony between resources and human needs. The objectives of this study are to identify the types of the interpretive methods used, and to evaluate their effectiveness, in marine parks. This study reviews the design principles of an effective interpretation for marine wildlife tourism, and adopts Drams' five design principles (1997) into a conceptual framework. Enjoyment increase, knowledge gain, attitude and intention change, and behaviour modification were used as key indicators in the assessment of the interpretive effectiveness of the Vancouver Aquarium (VA) and Marineland Canada (MC). Since on-site research is unavailable, a virtual tour is created to represent the interpretive experiences in the two study sites. Self-administered questionnaires are used to measure responses. Through comparing responses to the questionnaires (pre-, post-virtual tours and follow-up), this study found that interpretation increased enjoyment and added to respondents' knowledge. Although the changes in attitudes and intentions are not significant, the findings indicate that attitude and intention changes did occur as a result of interpretation, but only to a limited extent. Overall results suggest that more techniques should be added to enhance the effectiveness of the interpretation in marine parks or self-guiding tours, and with careful design, virtual tours are the innovative interpretation techniques for marine parks or informal educational facilities.

Scientific research in tourism: review of the literature from 2005 to 2009

This article presents the results of a review of the literature on tourism from 2005 to 2009. Precisely, 1,648 articles were reviewed and classified into eight macro-lines of research. The content of the Strategy macro-line was analyzed in greater depth, as it was considered to be an "umbrella" for the other dimensions pertinent to tourism. The literature thus provided significant elements confirming the appropriateness of the strategic network perspective for research on sustainable tourism management, and it also helped identify the actors that are most critical for leading the development of a tourist destination.

Introduction: digital methods and tools for historical research

As an introduction to a series of articles focused on the exploration of particular tools and/or methods to bring together digital technology and historical research, the aim of this paper is mainly to highlight and discuss in what measure those methodological approaches can contribute to improve analytical and interpretative capabilities available to historians. In a moment when the digital world present us with an ever-increasing variety of tools to perform extraction, analysis and visualization of large amounts of text, we thought it would be relevant to bring the digital closer to the vast historical academic community. More than repeating an idea of digital revolution introduced in the historical research, something recurring in the literature since the 1980s, the aim was to show the validity and usefulness of using digital tools and methods, as another set of highly relevant tools that the historians should consider. For this several case studies were used, combining the exploration of specific themes of historical knowledge and the development or discussion of digital methodologies, in order to highlight some changes and challenges that, in our opinion, are already affecting the historians' work, such as a greater focus given to interdisciplinarity and collaborative work, and a need for the form of communication of historical knowledge to become more interactive.

An integer-based score to predict functional outcome in acute ischemic stroke: The ASTRAL score.

OBJECTIVE: To develop and validate a simple, integer-based score to predict functional outcome in acute ischemic stroke (AIS) using variables readily available after emergency room admission. METHODS: Logistic regression was performed in the derivation cohort of previously independent patients with AIS (Acute Stroke Registry and Analysis of Lausanne [ASTRAL]) to identify predictors of unfavorable outcome (3-month modified Rankin Scale score >2). An integer-based point-scoring system for each covariate of the fitted multivariate model was generated by their β-coefficients; the overall score was calculated as the sum of the weighted scores. The model was validated internally using a 2-fold cross-validation technique and externally in 2 independent cohorts (Athens and Vienna Stroke Registries). RESULTS: Age (A), severity of stroke (S) measured by admission NIH Stroke Scale score, stroke onset to admission time (T), range of visual fields (R), acute glucose (A), and level of consciousness (L) were identified as independent predictors of unfavorable outcome in 1,645 patients in ASTRAL. Their β-coefficients were multiplied by 4 and rounded to the closest integer to generate the score. The area under the receiver operating characteristic curve (AUC) of the score in the ASTRAL cohort was 0.850. The score was well calibrated in the derivation (p = 0.43) and validation cohorts (0.22 [Athens, n = 1,659] and 0.49 [Vienna, n = 653]). AUCs were 0.937 (Athens), 0.771 (Vienna), and 0.902 (when pooled). An ASTRAL score of 31 indicates a 50% likelihood of unfavorable outcome. CONCLUSIONS: The ASTRAL score is a simple integer-based score to predict functional outcome using 6 readily available items at hospital admission. It performed well in double external validation and may be a useful tool for clinical practice and stroke research.

Challenges to patient-centred care in a general internal medicine context: findings from an exploratory study

Introduction. If we are to promote more patient-centred approaches in care delivery, we have to better characterize the situations in which being patient-centred is difficult to achieve. Data from professionals in health and social care are important because they are the people charged with operationalizing patient-centred care (PCC) in their daily practice. However, empirical accounts from frontline care providers are still lacking, and it is important to gather experiences not only from doctors but also from the other care providers. Indeed, experiences from different professions can help inform our understanding of patient care, which is expected to be both patient-centred and collaborative. Methods. This study was based on the following research question: What factors make the provision of PCC difficult to achieve? Sample and setting. A purposeful sampling technique was used, allowing for a series of choices about the participants and their professional affiliation. Because patient-centredness is the focus, 3 professions appeared to be of special interest: general internists, nurses and social workers. The study was undertaken in the General Internal Medicine Division of a teaching hospital located in a North American context. Data Collection. To answer the research question, a methodological approach based on a theory called phenomenology was chosen. Accordingly, semi-structured interviews were used since they generate understanding of the meanings different individuals have of their lived world. Interviews with 8 physicians, 10 nurses and 10 social workers were eventually conducted. Data analysis. An inductive thematic analysis was employed to make sense of the interview data. Results. The thematic analysis allowed identifying various types of challenges to PCC. Although most of the challenges were perceived by all three groups of professionals, they were perceived to a different degree across the professions, which likely reflected the scope of practice of each profession. The challenges and their distribution across the professions are illustrated in Table 1. Examples of challenges are provided in Table 2. Discussion. There is a tension between what is supposed to be done - what stands in the philosophy of patient -centredness - and what is currently done - the real life with all the challenges to PCC. According to some participants' accounts, PCC clearly risks becoming a mere illusion for health care professionals on which too great pressures are imposed.

Comparison of anaerobic threshold determined by visual and mathematical methods in healthy women

Several methods are used to estimate anaerobic threshold (AT) during exercise. The aim of the present study was to compare AT obtained by a graphic visual method for the estimate of ventilatory and metabolic variables (gold standard), to a bi-segmental linear regression mathematical model of Hinkley's algorithm applied to heart rate (HR) and carbon dioxide output (VCO2) data. Thirteen young (24 ± 2.63 years old) and 16 postmenopausal (57 ± 4.79 years old) healthy and sedentary women were submitted to a continuous ergospirometric incremental test on an electromagnetic braking cycloergometer with 10 to 20 W/min increases until physical exhaustion. The ventilatory variables were recorded breath-to-breath and HR was obtained beat-to-beat over real time. Data were analyzed by the nonparametric Friedman test and Spearman correlation test with the level of significance set at 5%. Power output (W), HR (bpm), oxygen uptake (VO2; mL kg-1 min-1), VO2 (mL/min), VCO2 (mL/min), and minute ventilation (VE; L/min) data observed at the AT level were similar for both methods and groups studied (P > 0.05). The VO2 (mL kg-1 min-1) data showed significant correlation (P < 0.05) between the gold standard method and the mathematical model when applied to HR (r s = 0.75) and VCO2 (r s = 0.78) data for the subjects as a whole (N = 29). The proposed mathematical method for the detection of changes in response patterns of VCO2 and HR was adequate and promising for AT detection in young and middle-aged women, representing a semi-automatic, non-invasive and objective AT measurement.

A Foucauldian Analysis of Power and Representation in an Attempt to Run a Photovoice Project with Youth

This project evolved out of a search for ways to conduct research on “others” in a way that does not exploit, stigmatize or misrepresent their experience. This thesis is an ethnographic study in leisure research and youth work and an experiment in running a photovoice project. Photovoice is a participatory visual method that embodies the emancipatory ideal of empowering others through self-representation. The literature on photovoice lacks a comprehensive discussion on the complexity of power and representation. Postmodern theorists have proposed that participatory methods are not benign and that initiatives are acts of power in themselves that produce effects (Cook & Kothari, 2001). A Foucauldian analysis of power is used to deconstruct the researcher’s practice and reflect on why and how youth are “engaged”. This project seeks to embrace the principle of working “with” others, but also work from a postmodern perspective that acknowledges power and representation as ongoing problems.
