In the latest years, the rapid progress of urban computing has engendered big issues, which creates both opportunities and challenges. The heterogeneous and big volume of data and the big difference between physical and virtual worlds have resulted in lots of problems in quickly solving practical problems in urban computing. In this paper, we propose a general application framework of ELM for urban computing. We present several real case studies of the framework like smog-related health hazard prediction and optimal retain store placement. Experiments involving urban data in China show the efficiency, accuracy, and flexibility of our proposed framework.

The OLAM model has as its characteristics the advantage to represent simultaneously the global and regional meteorological phenomena using the application of a grid refinement scheme. During the REMAM project the model was applied for a few case studies to evaluate its performance on numerical weather prediction for the eastern Amazon region. Case studies were performed for the twelve months of the year of 2009. The model results for those numerical experiments were compared with the observed data for the region of study. Precipitation data analysis showed that OLAM is able to represent the average mean accumulated precipitation and the seasonal features of the events occurrence, but can't predict the local total amount of precipitation. However, individual evaluation for a few cases had shown that OLAM was able to represent the dynamics and forecast a few days in advance the development of coastal meteorological systems such as the squall lines that are one of the most important precipitating systems of the Amazon.

BACKGROUND The INHERIT (INtersectoral Health and Environment Research for InnovaTion) project has evaluated intersectoral cooperation (IC) in 12 European case studies attempting to promote health, environmental sustainability, and equity through behavior and lifestyle changes. These factors are the concerns of multiple sectors of government and society. Cooperation of health and environmental sectors with other sectors is needed to enable effective action. IC is thus essential to promote a triple win of health, sustainability, and equity. OBJECTIVE This paper describes the design of a qualitative study to gain insights into successful organization of IC, facilitators and barriers, and how future steps can be taken to improve IC in the evaluated case studies. METHODS Each case study was assessed qualitatively through a focus group. A total of 12 focus groups in 10 different European countries with stakeholders, implementers, policymakers, and/or citizens were held between October 2018 and March 2019. Five to eight participants attended each focus group. The focus group method was based on appreciative inquiry, which is an asset-based approach focusing on what works well, why it is working well, and how to strengthen assets in the future. A stepped approach was used, with central coordination and analysis, and local implementation and reporting. Local teams were trained to apply a common protocol using a webinar and handbook on organizing, conducting, and reporting focus groups. Data were gathered in each country in the local language. Translated data were analyzed centrally using deductive thematic analysis, with consideration of further emerging themes. Analyses involved the capability, opportunity, motivation-behavior (COM-b) system to categorize facilitators and barriers into capability, motivation, or opportunity-related themes, as these factors influence the behaviors of individuals and groups. Web-based review sessions with representatives from all local research teams were held to check data analysis results and evaluate the stepped approach. RESULTS Data collection has been completed. A total of 76 individuals participated in 12 focus groups. In December 2019, data analysis was nearly complete, and the results are expected to be published in fall 2020. CONCLUSIONS This study proposes a stepped approach that allows cross-country focus group research using a strict protocol while dealing with language and cultural differences. The study generates insights into IC processes and facilitators in different countries and case studies to filter out which facilitators are essential to include. Simultaneously, the approach can strengthen cooperation among stakeholders by looking at future cooperation possibilities. By providing knowledge on how to plan for, improve, and sustain IC successfully to deal with today’s multisectoral challenges, this study can contribute to better intersectoral action for the triple win of better health, sustainability, and equity. This protocol can serve as a tool for other researchers who plan to conduct cross-country qualitative research. INTERNATIONAL REGISTERED REPORT RR1-10.2196/17323

It is usual that researchers, in the process of transcribing interviews or even during data analysis, realize that important issues were superficially mentioned by the interviewees, but for several possible reasons, these topics were not explored by the researcher in-depth or properly. It is also common during the interview to not realize that certain content evoked by the participants are connected to the research questions that originated the study. Similarly, some content brought in by the interviewees may seem confusing, contradictory, or even insufficient to be subjected to protocols of qualitative data analysis. This article aims to present a technique that allows researchers to have a deeper and more accurate understanding of the subjective topics that may emerge through a qualitative approach: the reflexive interview. This technique consists of the engagement of the interviewer and interviewee in the process of elaboration and collective understanding of the interviewee’s perspectives and experiences. Rather than only reporting their experiences descriptively, interviewees, with the support of interviewers, have the opportunity to share the meanings of the reality surrounding them and the events of their own lives, without being interpreted arbitrarily only by the interviewer. This article intends to conceptualize the reflexive interview, pointing out its benefits and the procedures necessary to employ it in a qualitative study. Two case studies are presented to the reader to illustrate the reflexivity processes that can engage participants through this resource, as well as how reflexive interviewing promotes a deep understanding of participants’ perspectives. Finally, general recommendations are provided, including examples of questions that can compose a script of a reflexive interview. It is hoped that this article provides a new resource for researchers interested in more accurately embodying participants’ perspectives and experiences.

AbstractThis research aims for knowing the implementation of Syariah principle towards the syariah bank operational viewed from financing perspective in the Bank of Muamalat dan the Bank of Syariah Bukopin in Makassar   The method used in the research is qualitative. The data analysis utilized descriptive-narative including reducing the data, presenting the data, and making the conclusion. In qualitative research, the examining of the data quality is so-called validity task where the approach used triangulation and member check.    The research designates that the Bank of Muamalat and the Bank of Syariah Bukopin implement syariah principle in their financing operational. The principle consists of profit-sharing principle and sale-purchase principle. The implementation of profit-sharing principle are Mudarabah and Musyarakah, while the sale-purchase principle is Murabahah.Keywords:     Syariah Principle, Financing, Mudarabah, Musyarakah and Murabahah
