https://www.ajqr.org/article/demystifying-the-user-experience-a-case-study-on-online-job-search-engines-11411
2021
Since the onset of the COVID-19 pandemic in 2020, the demand for job search engines has increased because of the availability of searching for remote job positions. However, there is still a lack of research on how people interact with different job search engines. It is critical to assess the effectiveness and efficiency of these tools for people searching for jobs because search engines help job seekers find positions that best fit their qualifications. This study assessed a job search engine by utilizing surveys, interviews, and observational methods to provide an improved understanding of individuals’ behavior and decision making in their search for career. The results showed that the job search engine needs improvement in the usability aspect because the website has an unintuitive interface and features, suggesting novice users may face difficulties in using it. The findings contribute to the limited body of literature that examines the user experiences in searching for jobs.

User Experience Matters: Does One size Fit all? Evaluation of Learning Management Systems
https://link.springer.com/article/10.1007/s10758-021-09518-1
2021
Learning Management Systems (LMS) are in use for years and are still crucial assets for both teachers and students for teaching and learning. There is a wide variety of LMS available for institutions to administer learning in and out of the classes. However, deciding to pick an LMS to integrate is a critical decision that affects both instructors and students. On the other hand, although there is previous research LMS from students' perspective, there is a lack of research in the literature from instructors' standpoint. This research aims to gain a deeper understanding of how in-service teachers, enrolled as students in the study program of instructional technology, use of LMS in terms of user experience and satisfaction of three well-known LMS, including Canvas, Blackboard, and Moodle. The results show a significant difference between the three LMS, Blackboard, Moodle, and Canvas, in terms of users’ subjective satisfaction, ease of use, and functionality.
Exploring the structural relationships between course design factors, learner commitment, self-directed learning, and intentions for further learning in a self-paced MOOC

2021
The open and massive characteristics of Massive Open Online Course (MOOC) lead to a lack of instructor presence, which potentially hinders learners' commitment and learning processes. As a result, the effectiveness of MOOCs is contingent upon the extent to which learners direct their own learning. However, learners' self-directed learning and commitment are largely influenced by course design factors due to lack of direct learner-instructor interactions. In order to address the current gap in the literature with regard to how course design factors influence learning processes and outcomes,this study investigated the relationships between MOOC design factors, learner commitment, self-directed learning, and intentions for future learning, using survey responses collected from 664learners who took a large-scale MOOC. We found that the transactional distance between learners and content was associated with students' self-directed learning. Course structure and organization predicted both students' self-directed learning and commitment to the MOOC. Importantly, self-directed learning mediated relationships between the course design factors and learners’ intentions for further learning. Based on our findings, we provide design strategies for effective learner-content interaction in large-scale self-paced MOOCs.
A fall risk evaluation and feedback system for older adults
https://www.igi-global.com/article/a-fall-risk-evaluation-and-feedback-system-for-older-adults/275746
2021
Falls are widespread among older adults causing serious injuries and threatening their quality of life. An approach to estimate fall risk, and to prevent falls, is the Timed-Up-and-Go (TUG) test. TheTUG test has established validity and reliability. However, as a clinical test, it is not accessible for personal use. To enhance its reach, the authors developed a prototype called Fall Risk Evaluation and Feedback System (FREFS). The prototype is a Kinect-based depth sensor system with interfaces that support older adults in completing the TUG test and receiving personalized test results. The personalized feedback feature is novel that existing prototypes do not include. This study's goal wasto gain knowledge of the user experience of FREFS. This research applied methods of observation,interviews, and collected responses on the System Usability Scale (SUS). Results show participants perceived the system as usable, with SUS score of 84.3, but also revealed issues. First, users were unsure how to deal with the TUG tests results when the results showed high fall risk. Second, clearer instructions and reduction of information overload specifically for these age groups were needed.Third, a communication approach embedded into the system would be required (i.e., a link to a chatbot feature or a button to connect to a real person). Overall, the study demonstrated that such a
prototype cannot be fully automated; it needs a sociotechnical system solution that includes human communication.
Keeping it peaceful: Twitter and the Gezi Park movement
https://journals.sagepub.com/doi/10.1177/2057047320959852
2020
Over the last decade, social media platforms have become the leading communication tools for activists and protesters all over the world. Understanding protesters’ motivations and reasons for using social media is a challenging issue for researchers. In this article, we analyzed the use of Twitter during the anti-governmental protests in Istanbul that was launched in May 2013. We examined13,794 tweets posted to the #direngeziparki hashtag over a 6-day period. Based on the results ofa qualitative content coding of the tweets, we found that the Twitter platform was widely used to mobilize protesters, share information about the events, and express opinions about the policing of the protests. We argue that social media can help keep protests peaceful by preventing vandalism,informing the protesters about extremist or violent groups participating in the protests, and can help them to avoid engaging in violent acts against police forces.
Fueling anti-Americanism in Turkey: Framing the news by the pro-government and international media
2020
Anti - Americanism is a growing tendency among people in Turkey, and media is one source of this negative sentiment. Upon the failed military coup attempt on 15 July 2016 in Turkey, more than 150 media outlets were shut down in the domestic media, including TV channels, daily newspapers, radio stations, news websites and even social media. However, the extensions of the international media companies, such as the BBC Turkish and Deutsche Welle Turkish, have remained immune to such government intervention s to some extent . Exploiting the difference in the level of independence of the media outlets, this study aims to explore how the U.S. related news in the same period varied on the Inter net across four different media sources. Drawing on the contents of 690 online news, a sentiment analysis was conducted by comparing the pro - government Sabah daily and Yeni Safak daily newspapers to internationally owned and more independent news outlets - BBC News Turkish and Deutsche Welle (DW). The results reveal a significant discrepancy between the two groups in terms of their framing of news related to the U.S. The domestic media framed and reported the US - related news comparatively with a more negative sentiment, including offensive and pejorative narratives against the U.S . and its politics. However, the BBC Turkish and DW Turkish reported the news about the U . S . with a relatively more neutral and objective language.
Strategic improvement planning in schools: A sociotechnical approach for understanding current practices and design recommendations
https://journals.sagepub.com/doi/abs/10.1177/0892020619847681?journalCode=miea
2019
The schools in the United States undergo reforms that involve the integration of data-intensive improvement process known as strategic improvement plans (SIPs). This process requires digital systems to set goals, create interventions, use and analyze student data, monitor and report SIPs. Achallenge with digital systems is the integration of a highly diverse set of data sources and identifying users who are engaged with the processes. This study explored how teachers and principals carryout SIPs currently. We applied the sociotechnical walkthrough, a qualitative method that combines a modelling notation and focus group interviews to understand the current workflows, technology use and interactions of teachers and principals developing SIPs. The results illustrate a variety of existing activities and indicate how a newly developed technology may have an impact as well as propose design recommendations to fill a gap in managing SIPs.

The characteristics of a particular user need to be evaluated to inform the design in the field of Human-Computer Interaction (HCI) design (Demir et al., 2017). This research consists of an evaluationof the characteristics of Asperger Syndrome (AS) and a budgeting tool has been proposed for children with the AS. The research results show that simplicity, consistency, color-coding and efficient labeling in design helps to reduce the cognitive load of the children with AS, thus, make the design more usable and useful for them.
The more complex the less success in online library services: Evaluating the user experience for international students
https://journals.uair.arizona.edu/index.php/itet/article/view/23007/21868
2018
The growing importance of web usability testing has led to improvements on millions of websites around the world. User Experience (UX) research involves use methods and procedures that inspect User Interfaces (UI) to identify the usability problems, pros, and cons of the design, and the level of user satisfaction (Demir, 2011). The increasing attention to the online applications has posed unlimited challenges, not just for the novice users, but also for the designers and creators of technology. As the demand for more efficient and powerful communication systems and technological equipment grows, the need for manufacturing companies to improve their products and services increases.Consequently, engineers and multimedia designers are continuously conducting usability tests to maketheir products more appealing and competitive in the global technology market. Usability research is a way to be responsive to the needs of consumers by systematically evaluating users’ behavior ina controlled environment (Clark, De Leon, Edgar, & Perrin, 2012). In regard to the library services,usability studies play a vital role in making sure that users can find the desired information on library websites swiftly and precisely (King, 2003).
A next-generation augmented reality mass casualty incident platform
https://uxpajournal.org/augmented-reality-casualty-incidents/
2017
It is vitally important to coordinate resources, information sharing, and two-way communication between medical incident commanders (ICs) and first medical responders (paramedics) at mass casualty incidents (MCI) sites. Information at the time of disasters also needs to be effectively analyzed and presented through intelligent user interfaces. Such interfaces need to be easy-to-use by ICs to foster critical decisions that can potentially reduce mortality rates. In this paper, wepresent Panacea’s Cloud™—a next-generation multiple casualty management system. This systemhas been iteratively developed and refined based on user experience research driven methodology that employed a mixed methods approach, including the views of clinical experts. Panacea’s Cloud™ is an example of a next generation MCI system that has an intelligent dashboard that integrates Internet-of-Things (IoT) technologies such as wearable devices and augmented reality technology (AR),virtual beacons, and sensor network nodes. It supports coordination between ICs and paramedics. Our
research demonstrates how IoT-based web applications, especially AR and the use of smart glasses,can be futuristically designed for purposes of smart healthcare applications that have effective and efficient communication capabilities. General design recommendations for next generation multiple casualty management system development include incorporating Situational Awareness features,a Synchronous Map View system, a Hands-Free Communication service with AR and smart glasses,Digital Notes, and resilient Wi-Fi networks.

Hierarchical Cloud-Fog Platform for Communication in Disaster Incident Coordination
https://ieeexplore.ieee.org/document/8710664
2019
Communication and coordination in a mass casualty disaster scenario is limited and difficult for medical personnel in the absence of necessary communication infrastructure and technologies that enable situation awareness. This leads to misdirected and delayed triage of scene-wide critically injured patients, especially when there are large numbers of patients needing diverse care levels. A hierarchical cloud-fog setup involving a core cloud and edge clouds (i.e., fogs) can help the patient triage related real-time data movement challenges. It can create visual situational awareness and overcome infrastructure limitations at the wireless network edge. In this paper, we describe our“Panacea's Cloud”, a hierarchical cloud-fog platform that provides augmented reality benefits withreal-time human communication and geo location services through the integration of a standardized Incident Command System (ICS) with smart devices such as heads-up displays, virtual beacons, and wireless mesh network elements. We show how the ICS can run using a core cloud as an intelligent dashboard that leverages fog resources and data collection close to the incident scenes. In addition,we describe experiment results from evaluations of Panacea's Cloud dashboard usability and platform performance that show benefits and issues in hierarchical cloud-fog service management in support of ICS communication during disaster incident coordination.
