Changes in physical activity following a genetic-based internet-delivered personalized intervention: randomized controlled trial (Food4Me)

Background: There is evidence that physical activity (PA) can attenuate the influence of the fat mass- and obesity-associated (FTO) genotype on the risk to develop obesity. However, whether providing personalized information on FTO genotype leads to changes in PA is unknown. Objective: The purpose of this study was to determine if disclosing FTO risk had an impact on change in PA following a 6-month intervention. Methods: The single nucleotide polymorphism (SNP) rs9939609 in the FTO gene was genotyped in 1279 participants of the Food4Me study, a four-arm, Web-based randomized controlled trial (RCT) in 7 European countries on the effects of personalized advice on nutrition and PA. PA was measured objectively using a TracmorD accelerometer and was self-reported using the Baecke questionnaire at baseline and 6 months. Differences in baseline PA variables between risk (AA and AT genotypes) and nonrisk (TT genotype) carriers were tested using multiple linear regression. Impact of FTO risk disclosure on PA change at 6 months was assessed among participants with inadequate PA, by including an interaction term in the model: disclosure (yes/no) × FTO risk (yes/no). Results: At baseline, data on PA were available for 874 and 405 participants with the risk and nonrisk FTO genotypes, respectively. There were no significant differences in objectively measured or self-reported baseline PA between risk and nonrisk carriers. A total of 807 (72.05%) of the participants out of 1120 in the personalized groups were encouraged to increase PA at baseline. Knowledge of FTO risk had no impact on PA in either risk or nonrisk carriers after the 6-month intervention. Attrition was higher in nonrisk participants for whom genotype was disclosed (P=.01) compared with their at-risk counterparts. Conclusions: No association between baseline PA and FTO risk genotype was observed. There was no added benefit of disclosing FTO risk on changes in PA in this personalized intervention. Further RCT studies are warranted to confirm whether disclosure of nonrisk genetic test results has adverse effects on engagement in behavior change.

Creative English and public relations in Hong Kong

This paper investigates employer perceptions of the nature and importance of the English language in public relations agencies in Hong Kong. Based on in-depth interviews with senior managers from eight Hong Kong-based public relations companies, it examines how the linguistic currency ofEnglish is used collaboratively in creative organizations. Findings suggest that English is used as the common language among transnational public relations work teams and the clients that they service. Itis also used as a creative resource for facilitating collaboration, staff development and socialization into corporate and professional cultures.

ANFIS BASED MODELS FOR ACCESSING QUALITY OF WIKIPEDIA ARTICLES

Wikipedia is a free, web-based, collaborative, multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Due to the free nature of Wikipedia and allowing open access to everyone to edit articles the quality of articles may be affected. As all people don’t have equal level of knowledge and also different people have different opinions about a topic so there may be difference between the contributions made by different authors. To overcome this situation it is very important to classify the articles so that the articles of good quality can be separated from the poor quality articles and should be removed from the database. The aim of this study is to classify the articles of Wikipedia into two classes class 0 (poor quality) and class 1(good quality) using the Adaptive Neuro Fuzzy Inference System (ANFIS) and data mining techniques. Two ANFIS are built using the Fuzzy Logic Toolbox [1] available in Matlab. The first ANFIS is based on the rules obtained from J48 classifier in WEKA while the other one was built by using the expert’s knowledge. The data used for this research work contains 226 article’s records taken from the German version of Wikipedia. The dataset consists of 19 inputs and one output. The data was preprocessed to remove any similar attributes. The input variables are related to the editors, contributors, length of articles and the lifecycle of articles. In the end analysis of different methods implemented in this research is made to analyze the performance of each classification method used.

Uma avaliacão fenomenográfica dos cursos suecos baseados na web

O propósito deste texto é discutir a avaliação de um curso superior oferecido por uma universidade sueca. Para tanto, parti de uma análise das avaliações feitas pelos estudantes, no ano de 2011-2012, quanto ao conteúdo, as aulas ministrada e a relação estabelecida entre o professor e os estudantes. O curso analisado foi o de Brasil Contemporâneo, da Universidade de Dalarna. O curso é oferecido na forma EBW e faz parte da graduação em Português.       As conclusões alcançadas e fundamentadas na análise do questionários  apontam para uma necessidade de uma sistematização do conteúdo e de uma melhor exposição do mesmo. Os estudantes, na sua maoria estrangeiros, têm uma percepção sobre a realidade brasileira que ao se contrapor à literatura do curso leva-os a reverem e a redefinirem a imagem que os mesmos tinham sobre o Brasil. Entrentanto, as avaliações apontam para a necessidade de desenvolvimento e formento de trabalhos em grupos que auxiliam na aprendizagem dos estudantes. Esta é um importante desáfio dos cursos baseados na Web, na rede de ensino superior sueca.

A web application for follow-up of results from a mobile device test battery for parkinson’s disease patients

Background: A test battery consisting of self-assessments and motor tests (tapping and spiral drawing) was developed for a hand computer with touch screen in a telemedicine setting. Objectives: To develop and evaluate a web-based system that delivers decision support information to the treating clinical staff for assessing PD symptoms in their patients based on the test battery data. Methods: The test battery is currently being used in a clinical trial (DAPHNE, EudraCT No. 2005-002654-21) by sixty five patients with advanced Parkinson’s disease (PD) on 9991 test occasions (four tests per day during in all 362 week-long test periods) at nine clinics around Sweden. Test results are sent continuously from the hand unit over a mobile net to a central computer and processed with statistical methods. They are summarized into scores for different dimensions of the symptom state and an ‘overall test score’ reflecting the overall condition of the patient during a test period. The information in the web application is organized and presented graphically in a way that the general overview of the patient performance per test period is emphasized. Focus is on the overall test score, symptom dimensions and daily summaries. In a recent preliminary user evaluation, the web application was demonstrated to the fifteen study nurses who had used the test battery in the clinical trial. At least one patient per clinic was shown. Results: In general, the responses from nurses were positive. They claimed that the test results shown in the system were consistent with their own clinical observations. They could follow complications, changes and trends within their patients. Discussion: In conclusion, the system is able to summarise the various time series of motor test results and self-assessments during test periods and present them in a useful manner. Its main contribution is a novel and reliable way to capture and easily access symptom information from patients’ home environment. The convenient access to current symptom profile as well as symptom history provides a basis for individualized evaluation and adjustment of treatments.

Visualization of spirography-based objective measures in Parkinson's disease

Objective: To investigate whether advanced visualizations of spirography-based objective measures are useful in differentiating drug-related motor dysfunctions between Off and dyskinesia in Parkinson’s disease (PD). Background: During the course of a 3 year longitudinal clinical study, in total 65 patients (43 males and 22 females with mean age of 65) with advanced PD and 10 healthy elderly (HE) subjects (5 males and 5 females with mean age of 61) were assessed. Both patients and HE subjects performed repeated and time-stamped assessments of their objective health indicators using a test battery implemented on a telemetry touch screen handheld computer, in their home environment settings. Among other tasks, the subjects were asked to trace a pre-drawn Archimedes spiral using the dominant hand and repeat the test three times per test occasion. Methods: A web-based framework was developed to enable a visual exploration of relevant spirography-based kinematic features by clinicians so they can in turn evaluate the motor states of the patients i.e. Off and dyskinesia. The system uses different visualization techniques such as time series plots, animation, and interaction and organizes them into different views to aid clinicians in measuring spatial and time-dependent irregularities that could be associated with the motor states. Along with the animation view, the system displays two time series plots for representing drawing speed (blue line) and displacement from ideal trajectory (orange line). The views are coordinated and linked i.e. user interactions in one of the views will be reflected in other views. For instance, when the user points in one of the pixels in the spiral view, the circle size of the underlying pixel increases and a vertical line appears in the time series views to depict the corresponding position. In addition, in order to enable clinicians to observe erratic movements more clearly and thus improve the detection of irregularities, the system displays a color-map which gives an idea of the longevity of the spirography task. Figure 2 shows single randomly selected spirals drawn by a: A) patient who experienced dyskinesias, B) HE subject, and C) patient in Off state. Results: According to a domain expert (DN), the spirals drawn in the Off and dyskinesia motor states are characterized by different spatial and time features. For instance, the spiral shown in Fig. 2A was drawn by a patient who showed symptoms of dyskinesia; the drawing speed was relatively high (cf. blue-colored time series plot and the short timestamp scale in the x axis) and the spatial displacement was high (cf. orange-colored time series plot) associated with smooth deviations as a result of uncontrollable movements. The patient also exhibited low amount of hesitation which could be reflected both in the animation of the spiral as well as time series plots. In contrast, the patient who was in the Off state exhibited different kinematic features, as shown in Fig. 2C. In the case of spirals drawn by a HE subject, there was a great precision during the drawing process as well as unchanging levels of time-dependent features over the test trial, as seen in Fig. 2B. Conclusions: Visualizing spirography-based objective measures enables identification of trends and patterns of drug-related motor dysfunctions at the patient’s individual level. Dynamic access of visualized motor tests may be useful during the evaluation of drug-related complications such as under- and over-medications, providing decision support to clinicians during evaluation of treatment effects as well as improve the quality of life of patients and their caregivers. In future, we plan to evaluate the proposed approach by assessing within- and between-clinician variability in ratings in order to determine its actual usefulness and then use these ratings as target outcomes in supervised machine learning, similarly as it was previously done in the study performed by Memedi et al. (2013).

AvalWeb : sistema interativo para gerência de questões e aplicação de avaliações na web

Neste trabalho, é realizado um estudo dos processos de avaliação de alunos em ambiente WBT (Web Based Training). Para tanto, foram analisadas várias ferramentas de avaliação disponíveis no mercado. Com base nestas análises, foi proposto um sistema de gerência de questões e aplicação de avaliações, onde o termo “gerência” é utilizado com o objetivo de (i) atender requisições dos professores para elaboração de avaliações, (ii) escolher o nível de dificuldade das questões que comporão a avaliação e (iii) usar estratégias interativas para aplicação de provas, como por exemplo, a utilização de níveis de dificuldade progressivos das questões submetidas aos alunos, dependendo de suas respostas anteriores. Integrando o sistema de gerência de questões foi proposto um módulo de auto-avaliações, com retorno imediato para o aluno sobre qual é a resposta correta juntamente com uma explicação do professor, auxiliando no entendimento do estudante sobre a matéria ao invés de simplesmente atribuir determinada nota. Enfim, foi implementado um protótipo demonstrando a viabilidade das idéias presentes no modelo de avaliação aqui proposto. A proposta conceitual estabelecida para o modelo é bem mais ampla e flexível do que a atual versão da implementação realizada.

A democratização da política pública e o fortalecimento da cidadania. Conhecendo o projeto Casa Brasil : unidades Vitória e Vila Velha

The purpose of this dissertation is to analyze the Casa Brasil Project and its contribution for promoting actions related to citizenship in Vitoria and Vila Velha cities. The essay was led through a theoretical discussion about citizenship, public space, social participation and public politics. Thereafter thematic interviews based on a non-probabilistic method were done with seventeen people such as public power representatives, organized civilian society and community. The speech analysis was used for data treatment. Some negative and positive aspects referred to citizenship and public power were identified. The aim of the research was checking if there is any encouragement to a genuine and consciousness participation of the society for the structure and continuous citizenship practice. The Casa Brasil Project experience in Vitoria and Vila Velha demonstrates that its sustainability and effectiveness depend on how interacted and committed the strategic stakeholders are, since the condition of local institutions influences the model of social mobilization and individual participation. Besides, this essay shows it is necessary: to improve the citizen involvement ¿ by implementing the board of directors, which assures public participation in order to stimulate the community to take the unity control ¿ to grant democratic feature to the public power, and to increase citizenship.

A criação de um ambiente regulatório no Brasil: mecanismos de controle social e o processo de institucionalização das agências reguladoras federais

Mudanças recentes no ambiente regulatório brasileiro demandam a criação de um novo contexto institucional que permita uma melhor articulação na relação entre Estado e sociedade, em especial no que se refere aos mecanismos de controle social. A nova experiência baseada na criação de “agências reguladoras” no Brasil evidencia as deficiências de sua lógica. O trabalho apresentado, a partir de revisões da teoria institucional e da regulação, examina o surgimento e funcionamento do atual quadro regulatório brasileiro, e constrói um modelo que considera a inter-relação entre as dinâmicas institucionais das esferas social e política e, conseqüentemente, em uma real participação pública no processo de regulação.

Participação pública em programas ambientais :um estudo em área suscetível à desertificação no Estado do Rio Grande do Norte

The natural resources degradation and its consequences to the society life have provided several discussions about the evaluation methods and environmental management, and the available means to minimize the effects of man s actions over the environment. Amongst these actions is the encouragement to the community participation in the process of carrying out the environmental programs, considering government and enterprises representatives or residents of certain places as social actors. Within these context, this paper had as a goal the investigation of the public participation in the environmental programs in areas that are susceptible to desertification, specificly in Parelhas/RN. The choice for this town was due to its insertion in an area considered as a desetification nucleous, which is, a region that suffers land degradation as a consequence of climate variations or human activities. Therefore, the research in question, of a descriptive and exploratory type, had as an instrument a structured questionnaire, applied to a sample of 223 people out of an 11,068 over 20 years of age residents population. The data have been tabled from Statistics for Windows Program and later interpreted based on the theoretical reference over the subject. As a result, corroborating to the literature of the area, it was found that the community participation in any type of action or debate about environmental questions is associated to the perception and knowledge about the problems. Although the people who were interviewed believe in the responsibility of the ceramic industry in causing environmental problems, they also believe that the benefits brought by the sector overcome such problems

High expectations, varying outcomes: Decentralization and participation in Brazil, Japan, Russia and Sweden

In the past 20 years, decentralization has been proposed as a strategy for enhancing public participation. Aid-providing organizations, such as the World Bank, stimulated decentralization processes in several countries in the hope that this would promote civic empowerment, diminish corruption, enhance efficiency, and improve public service delivery. This assumption forms the basis for a comparative analysis into the relation between decentralization and participation at the local level in Brazil, Japan, Russia and Sweden. A multi-level regression analysis using the data of the Democracy and Local Governance Project was undertaken in order to test the 'one size fits all' and the 'diversity in development' hypotheses. The results show that the second hypothesis was corroborated. Perceived autonomy had a different impact on openness to participation depending on the country considered; in one country (Japan), perceived autonomy diminished public officials' willingness to be open to public participation.

The multimedia system is integrated with a real robotic arm, which was also developed at the university. Through robotic topic presentations and interactive capabilities provided by this system and its tools, students can devote themselves on the learning process just as they do in the traditional face-to-face classes. and the target public of this system are the engineering students themselves.

Utilizing cross-domain SOAP Web services using client-side languages in an enterprise mashup platform

Service oriented architectures (SOA) based on Simple Object Access Protocol (SOAP) Web services have attracted the attention of enterprises mainly for business-to-business integration and to create composite applications that execute business processes. An existing problem is the lack of preoccupation with non technical users due to the fact that to create a composite application to fulfill users needs, it is necessary to be in contact with IT staff. To overcome this issue, enterprises can take advantage of web 2.0, 'introducing in the development stage some technologies like mashups and some concepts like user empowerment, collaborative work and collective intelligence. Some results [3] [13] have shown how web 2.0 concepts can help non technical users to produce relative complex business processes. However, traditional enterprise requirements goes beyond typical web 2.0 solutions in several aspects: (1) traditional enterprise systems are based on heterogeneous stack of technologies that are not directly exploitable from a web-based client (where SOAP web services play an important role); (2) web browsers set some cross-domain security constraints making difficult to integrate services from diverse domains. In this paper, a contribution to two web 2.0 research projects [14] [15] partially solves the problems described: provide a way to invoke cross-domain backend services (based on SOAP technologies) directly only using clientside languages, without a need for any adaptation layer. © 2010 ACM.
