Koala: sistema para integração de métodos de predição e análise de estruturas de proteína

A Biologia Computacional tem desenvolvido algoritmos aplicados a problemas relevantes da Biologia. Um desses problemas é a Protein Structure Prediction (PSP). Vários métodos têm sido desenvolvidos na literatura para lidar com esse problema. Porém a reprodução de resultados e a comparação dos mesmos não têm sido uma tarefa fácil. Nesse sentido, o Critical Assessment of protein Structure Prediction (CASP), busca entre seus objetivos, realizar tais comparações. Além disso, os sistemas desenvolvidos para esse problema em geral não possuem interface amigável, não favorecendo o uso por não especialistas da computação. Buscando reduzir essas dificuldades, este trabalho propões o Koala, um sistema baseado em uma plataforma web, que integra vários métodos de predição e análises de estruturas de proteínas, possibilitando a execução de experimentos complexos com o uso de fluxos de trabalhos. Os métodos de predição disponíveis podem ser integrados para a realização de análises dos resultados, usando as métricas RMSD, GDT-TS ou TM-Score. Além disso, o método Sort by front dominance (baseado no critério de optimalidade de Pareto), proposto nesse trabalho, consegue avaliar predições sem uma estrutura de referência. Os resultados obtidos, usando proteínas alvo de artigos recentes e do CASP11, indicam que o Koala tem capacidade de realizar um conjunto relativamente grande de experimentos estruturados, beneficiando a determinação de melhores estruturas de proteínas, bem como o desenvolvimento de novas abordagens para predição e análise por meio de fluxos de trabalho.

Asking For Help: Vulnerability within Consultative Assessment A Couples Therapy Example.

In many different ways psychologists are challenged to evaluate their work and be accountable when therapy is not progressing. One time honored approach to addressing the lack of progress is to seek formal psychological assessment to gain a better diagnostic understanding as well as treatment recommendations. The perspective on the purpose of the assessment seems to have changed however. Historically, the presumption was that there was some kind of pathology that the clinician was not seeing, where currently the perspective seems to be shifting more towards a focus on what might not be working in the therapeutic process. This shift in focus has led to new styles of collaborative and consultative assessment such as Therapeutic Assessment. Therapeutic Assessment was developed by Stephen Finn and has shown a great deal of promise helping clients and therapists gain valuable insight and move toward meaningful life changes (1998). Amidst the promise of consultative assessment also lie potential challenges for the referring clinician. This paper will explore the nature of consultative relationships in the field of mental health and the current thoughts about the advantages and challenges of these relationships. Using a case study format, it will discuss and illustrate issues of professional vulnerability that can arise during these relationships and postulate that a similar vulnerability could be present during a consultative assessment. Recommendations are made for maximizing the success of this type of assessment, and ideas for future research are reviewed. Through the lens of a couples Therapeutic Assessment case, this paper will examine what it is about this unique kind of professional relationship that garners such powerful potential and pitfalls.

Ambientes tecno-pedagógicos para o desenvolvimento de competências transversais para a inovação em engenharia.

Muito se fala na crescente velocidade de inovações tecnológicas que se apresenta ao mundo e que vai se acelerando. Antes, gerações se passavam para termos uma evolução tecnológica. Hoje, uma mesma geração presencia vários saltos tecnológicos. Neste contexto de inovações frequentes, surge a preocupação sobre como formar um profissional responsável, ético e que consiga acompanhar e ser protagonista de tais mudanças. O trabalho desenvolvido nesta tese busca colaborar na discussão sobre a formação do engenheiro, com foco na engenharia elétrica e de computação, revisitando as definições de conceitos como educação em engenharia, aprendizagem ativa, inovação, Design Thinking e competências transversais, e definindo, como contribuição de pesquisa, os conceitos de tecno-pedagogia e ambientes tecno-pedagógicos, como pressuposto de convergência de estruturas tecnológicas, estratégias pedagógicas e métodos de avaliação em aprendizagem ativa para a inovação. Apresenta um método para identificar e quantificar o grau de ênfase das competências transversais para a inovação a partir da demanda de mercado para engenheiros eletricistas e da computação; e um método de observação, coleta e análise de dados sobre o desenvolvimento de competências transversais na participação em duas experiências de aula: na disciplina global ME310 da Universidade de Stanford; e na disciplina 030-3410 da Escola Politécnica da Universidade de São Paulo. Com isso, foi possível elaborar um método para auxiliar no planejamento de disciplinas e cursos com foco em inovação, identificando as competências transversais que devem ser incentivadas e relacionando tais competências com estratégias de ensino e aprendizagem e sugerindo a estrutura tecnológica e método de avaliação a serem adotados.

Constructing the Vulvar Pain Assessment Questionnaire Inventory

The goals of this program of research were to examine the link between self-reported vulvar pain and clinical diagnoses, and to create a user-friendly assessment tool to aid in that process. These goals were undertaken through a series of four empirical studies (Chapters 2-6): one archival study, two online studies, and one study conducted in a Women’s Health clinic. In Chapter 2, the link between self-report and clinical diagnosis was confirmed by extracting data from multiple studies conducted in the Sexual Health Research Laboratory over the course of several years. We demonstrated the accuracy of diagnosis based on multiple factors, and explored the varied gynecological presentation of different diagnostic groups. Chapter 3 was based on an online study designed to create the Vulvar Pain Assessment Questionnaire (VPAQ) inventory. Following the construct validation approach, a large pool of potential items was created to capture a broad selection of vulvar pain symptoms. Nearly 300 participants completed the entire item pool, and a series of factor analyses were utilized to narrow down the items and create scales/subscales. Relationships were computed among subscales and validated scales to establish convergent and discriminant validity. Chapters 4 and 5 were conducted in the Department of Obstetrics & Gynecology at Oregon Health & Science University. The brief screening version of the VPAQ was employed with patients of the Program in Vulvar Health at the Center for Women’s Health. The accuracy and usefulness of the VPAQscreen was determined from the perspective of patients as well as their health care providers, and the treatment-seeking experiences of patients was explored. Finally, a second online study was conducted to confirm the factor structure, internal consistency, and test-retest reliability of the VPAQ inventory. The results presented in these chapters confirm the link between targeted questions and accurate diagnoses, and provide a guideline that is useful and accessible for providers and patients.

Screening for physical activity in family practice - Evaluation of two brief assessment tools

Background: Physical activity (PA) is relevant to the prevention and management of many health conditions in family practice. There is a need for an efficient, reliable, and valid assessment tool to identify patients in need of PA interventions. Methods: Twenty-eight family physicians in three Australian cities assessed the PA of their adult patients during 2004 using either a two- (2Q) or three-question (3Q) assessment. This was administered again approximately 3 days later to evaluate test-retest reliability. Concurrent validity was evaluated by measuring agreement with the Active Australia Questionnaire, and criterion validity by comparison with 7-day Computer Science Applications, Inc. (CSA) accelerometer counts. Results: A total of 509 patients participated, with 428 (84%) completing a repeat assessment, and 415 (82%) accelerometer monitoring. The brief assessments had moderate test-retest reliability (2Q k = 58.0%, 95% confidence interval [CI] = 47.2-68.8%; 3Q k = 55.6%, 95% CI = 43.8-67.4%); fair to moderate concurrent validity (2Q k = 46.7%, 95% CI = 35.657.9%; 3Q k = 38.7%, 95% CI = 26.4-51.1%); and poor to fair criterion validity (2Q k = 18.2%, 95% CI = 3.9-32.6%; 3Q k = 24.3%, 95% CI = 11.6-36.9%) for identifying patients as sufficiently active. A four-level scale of PA derived from the PA assessments was significantly correlated with accelerometer minutes (2Q rho = 0.39, 95% CI = 0.28-0.49; 3Q rho = 0.31, 95% CI = 0.18-0.43). Physicians reported that the assessments took I to 2 minutes to complete. Conclusions: Both PA assessments were feasible to use in family practice, and were suitable for identifying the least active patients. The 2Q assessment was preferred by clinicians and may be most appropriate for dissemination.

The mismatch negativity (MMN) response to complex tones and spoken words in individuals with aphasia

Background: The mismatch negativity (MMN) is a fronto-centrally distributed event-related potential (ERP) that is elicited by any discriminable auditory change. It is an ideal neurophysiological tool for measuring the auditory processing skills of individuals with aphasia because it can be elicited even in the absence of attention. Previous MMN studies have shown that acoustic processing of tone or pitch deviance is relatively preserved in aphasia, whereas the basic acoustic processing of speech stimuli can be impaired (e.g., auditory discrimination). However, no MMN study has yet investigated the higher levels of auditory processing, such as language-specific phonological and/or lexical processing, in individuals with aphasia. Aims: The aim of the current study was to investigate the MMN response of normal and language-disordered subjects to tone stimuli and speech stimuli that incorporate the basic auditory processing (acoustic, acoustic-phonetic) levels of non-speech and speech sound processing, and also the language-specific phonological and lexical levels of spoken word processing. Furthermore, this study aimed to correlate the aphasic MMN data with language performance on a variety of tasks specifically targeted at the different levels of spoken word processing. Methods M Procedures: Six adults with aphasia (71.7 years +/- 3.0) and six healthy age-, gender-, and education-matched controls (72.2 years +/- 5.4) participated in the study. All subjects were right-handed and native speakers of English. Each subject was presented with complex harmonic tone stimuli, differing in pitch or duration, and consonant-vowel (CV) speech stimuli (non-word /de:/versus real world/deI/). The probability of the deviant for each tone or speech contrast was 10%. The subjects were also presented with the same stimuli in behavioural discrimination tasks, and were administered a language assessment battery to measure their auditory comprehension skills. Outcomes O Results: The aphasic subjects demonstrated attenuated MMN responses to complex tone duration deviance and to speech stimuli (words and non-words), and their responses to the frequency, duration, and real word deviant stimuli were found to strongly correlate with performance on the auditory comprehension section of the Western Aphasia Battery (WAB). Furthermore, deficits in attentional lexical decision skills demonstrated by the aphasic subjects correlated with a word-related enhancement demonstrated during the automatic MMN paradigm, providing evidence to support the word advantage effect, thought to reflect the activation of language-specific memory traces in the brain for words. Conclusions: These results indicate that the MMN may be used as a technique for investigating general and more specific auditory comprehension skills of individuals with aphasia, using speech and/or non-speech stimuli, independent of the individual's attention. The combined use of the objective MMN technique and current clinical language assessments may result in improved rehabilitative management of aphasic individuals.

Ten Australian elementary teachers' discourse and reported pedagogical practices during cooperative learning

This article describes the types of discourse 10 Australian grade 4-6 teachers used after they had been trained to embed cooperative learning in their curriculum and to use communication skills to promote students' thinking and to scaffold their learning. One audiotaped classroom social science lesson involving cooperative learning was analyzed for each teacher. We provide vignettes from 2 teachers as they worked with groups and from 2 student groups. The data from the audiotapes showed that the teachers used a range of mediated-learning behaviors in their interactions with the children that included challenging their perspectives, asking more cognitive and metacognitive questions, and scaffolding their learning. In turn, in their interactions with each other, the children modelled many of the types of discourse they heard their teachers use. Follow-up interviews with the teachers revealed that they believed it was important to set expectations for children's group behaviors, teach the social skills students needed to deal with disagreement in groups, and establish group structures so children understood what was required both from each other and the task. The teachers reported that mixed ability and gender groups worked best and that groups should be no larger than 5 students. All teachers' programs were based on a child-centered philosophy that recognized the importance of constructivist approaches to learning and the key role interaction plays in promoting social reasoning and learning.

Quel role pour la langue de reference dans les representations des apprenants? Le cas de l'evaluation en langue etrangere

This research project explores learner’s representations of strategic L1 use in the foreign language classroom and highlights both the positive or negative roles attributed to the L1 in the language learning process - particularly with respect to language assessment - continuing to explore the relatively understudied domain of student representations within a scholarly context. Surveying a population of Australian (N=18) and French students (N=25), this study uses both questionnaire and interview responses in order to analyse the roles allocated to the L1 with respect to learning outcomes. The results indicate that students have a very balanced view of the L1 with respect to the learning of grammar, vocabulary and social aspects, yet its use in assessment aspects appears much more advantageous. The importance of this study and its findings is in recognizing the complex nature of learner representations in order to facilitate a discussion that is based more on the reality of language teaching, with the hope of renewing classroom practices.

Analytic hierarchy process helps evaluate projects in Indian oil pipeline industry

Conventionally, oil pipeline projects are evaluated thoroughly by the owner before investment decision is made using market, technical and financial analysis sequentially. The market analysis determines pipelines throughput and supply and demand points. Subsequent, technical analysis identifies technological options and economic and financial analysis then derives the least cost option among all technically feasible options. The subsequent impact assessment tries to justify the selected option by addressing environmental and social issues. The impact assessment often suggests alternative sites, technologies, and/or implementation methodology, necessitating revision of technical and financial analysis. This study addresses these issues via an integrated project evaluation and selection model. The model uses analytic hierarchy process, a multiple-attribute decision-making technique. The effectiveness of the model has been demonstrated through a case application on cross-country petroleum pipeline project in India.

A virtual learning environment for operations management:Assessing the student's perspective

This paper describes a project aimed at assessing the experience of a virtual learning environment (VLE) among students studying courses in operations management. The project was supported by the Higher Education Funding Council for England (HEFCE) under its Teaching Quality Enhancement Fund (TQEF). The main aim of the project was through the use of a questionnaire to establish the student experience of using a VLE through an examination of the learning and technical features which they encountered. The study also examines the approaches to learning adopted by the students, through the inclusion of a shortened version of the approaches and study skills inventory for students (ASSIST) which the students were asked to complete.

Achieving continuous improvement through self-assessment

In 2007 the UK Office of Government Commerce was mandated to carry out Procurement Capability Reviews (PCR) across the 16 top spending UK Government Departments. Since then, this programme has evolved into a self assessment based approach which is markedly different from the original approach. Will the move from a centre-led strategic review of procurement capability to a department-led model based on self assessment continue to strengthen and improve procurement capability across Central Civil Government? OGC is currently working with UK Government Departments to carry out their PCRs using a self-assessment tool which incorporates qualitative and quantitative measures. Results are generated based on a capability maturity model. The results are assured independently. OGC expectations are that tangible and measurable capability improvements will be realised when departments embed the self-assessment model and implement the findings as part of a continuous improvement regime. This paper is a case study, using some relevant literature to reflect on past and possible future development of the PCR self assessment scheme.

Evacuation responsiveness by government organisations (ERGO):the evacuation preparedness assessment workbook

This Evacuation Preparedness Assessment Workbook (EPAW) is a tool to assess the level of preparedness of Government Organisations (GOs) for the mass evacuation of their public. It has its origins in the results of a three-year, EU-funded research project called Evacuation Preparedness by Government Organisations (ERGO) which sought to research and strengthen the preparedness activities for the evacuation of cities, regions or even countries. This EPAW presents a list of tasks to be carried out at the different phases of evacuation preparedness. It also provides an assessment facility to evaluate how much progress GOs have made against each task, as well as indications of standard and best practices for each task. A brief background to the need for evacuation, the ERGO project and the development of the workbook is given next. After this, the application process of the workbook is explained and illustrated with an example.
