Data and Experience Design: Negotiating Community-Oriented Digital Research with Service-Learning

In this research with reflection paper, we discuss our experiences from a graduate level service learning course in which we assisted the local food bank on exploring the efficiency of their client tracking software, Link2Feed. In the semester-long project, we developed a close relationship with the staff of the community partner and worked to explore functionality and usability (Johnson, Salvo, & Zoetewey, 2007; Johnson, 2010) of Link2Feed. Throughout the semester, we applied various academic skills like taking interviews, rhetorical analysis of the software, and analyzing the community partner needs and how the software meets those needs. At the end of the semester, we were able to provide a detailed report on the features of the Link2Feed and its embedded functions. We also found ways to address the current needs of the partner organization for big data collection, reporting, and visualization. With the framework of experience architecture (Potts & Salvo, 2017) and workplace-based writing and communication and composition with community, we discuss the challenges of negotiating the needs of the community partner, their infrastructural limitations (DeVoss, Cushman, & Grabill, 2005), and the use of academic research to enhance the community partner’s efficiency to generate big data and knowledge via digital technologies. In this paper, we also reflect on the overall process of conducting a semester-long service learning/ community engagement project and the challenges and benefits of negotiating community partner’s priorities, the challenges in investigating an unfamiliar software platform, and the importance of regular communication with the professor

Middleware Technologies for Cloud of Things - a survey

The next wave of communication and applications rely on the new services provided by Internet of Things which is becoming an important aspect in human and machines future. The IoT services are a key solution for providing smart environments in homes, buildings and cities. In the era of a massive number of connected things and objects with a high grow rate, several challenges have been raised such as management, aggregation and storage for big produced data. In order to tackle some of these issues, cloud computing emerged to IoT as Cloud of Things (CoT) which provides virtually unlimited cloud services to enhance the large scale IoT platforms. There are several factors to be considered in design and implementation of a CoT platform. One of the most important and challenging problems is the heterogeneity of different objects. This problem can be addressed by deploying suitable "Middleware". Middleware sits between things and applications that make a reliable platform for communication among things with different interfaces, operating systems, and architectures. The main aim of this paper is to study the middleware technologies for CoT. Toward this end, we first present the main features and characteristics of middlewares. Next we study different architecture styles and service domains. Then we presents several middlewares that are suitable for CoT based platforms and lastly a list of current challenges and issues in design of CoT based middlewares is discussed.Comment: http://www.sciencedirect.com/science/article/pii/S2352864817301268, Digital Communications and Networks, Elsevier (2017

Challenges to describe QoS requirements for web services quality prediction to support web services interoperability in electronic commerce

Quality of service (QoS) is significant and necessary for web service applications quality assurance. Furthermore, web services quality has contributed to the successful implementation of Electronic Commerce (EC) applications. However, QoS is still the big issue for web services research and remains one of the main research questions that need to be explored. We believe that QoS should not only be measured but should also be predicted during the development and implementation stages. However, there are challenges and constraints to determine and choose QoS requirements for high quality web services. Therefore, this paper highlights the challenges for the QoS requirements prediction as they are not easy to identify. Moreover, there are many different perspectives and purposes of web services, and various prediction techniques to describe QoS requirements. Additionally, the paper introduces a metamodel as a concept of what makes a good web service
