Abstract: Video annotation (VA), a tool which allows commentaries to be synchronized with video content has recently received significant research attention in education. However, the application contexts of these studies are varied and fragmented. A review was therefore undertaken with the objectives to find out the extent to which the use of VA has been explored for different instructional purposes and summarize the potential affordances of VA in supporting student learning. Articles related to the use of VA in education context were searched from 2011 to 2020 (Nov). Of the final 32 eligible studies, it was found that VA tools were used predominantly to develop teaching practices, enhance learners’ conceptual understanding of video content and develop workplace skills as well as clinical practices. Five most dominant educational affordances of VA tools were summarized as follows: (1) facilitating learners’ reflection (2) facilitating feedback process (3) enhancing comprehension of video content (4) promoting students’ learning satisfaction and positive attitude and (5) convenience and ease. With the outstanding weight of research evidence gained on educational affordances offered by VA, it is convincing that advancing the use of VA in education can further expand the learning opportunities in 21st century classrooms.    Keywords: Affordances, Education, Feedback, Learners’ reflection, Video annotation

AbstractOne realm of AI, recommender systems have attracted significant research attention due to concerns about its devastating effects to society’s most vulnerable and marginalised communities. Both media press and academic literature provide compelling evidence that AI-based recommendations help to perpetuate and exacerbate racial and gender biases. Yet, there is limited knowledge about the extent to which individuals might question AI-based recommendations when perceived as biased. To address this gap in knowledge, we investigate the effects of espoused national cultural values on AI questionability, by examining how individuals might question AI-based recommendations due to perceived racial or gender bias. Data collected from 387 survey respondents in the United States indicate that individuals with espoused national cultural values associated to collectivism, masculinity and uncertainty avoidance are more likely to question biased AI-based recommendations. This study advances understanding of how cultural values affect AI questionability due to perceived bias and it contributes to current academic discourse about the need to hold AI accountable.

Antecedents And Consequences

Online word-of-mouth (WOM) has received significant research attention as the Internet has rapidly developed. Owing to specific Internet platforms such as consumer reviews sites and social network sites, online WOM spreads much more quickly and widely than traditional WOM, and that phenomenon ultimately makes online WOM play a key role in a consumer's purchase decision. In this chapter we present an overview of previous research on online WOM to facilitate future research in this area. In this review, previous researches are divided into three streams, i.e., (1) the effectiveness of online WOM, (2) the valence of online WOM, and (3) the antecedents and consequences of online WOM. Also, two possible future research directions are suggested at the end the chapter.

Job Search Methods

This review distills available empirical research about the process and experience of looking for a job. Job search varies according to several dimensions, including intensity, content, and temporality/persistence. Our review examines how these dimensions relate to job search success, which involves job finding as well as job quality. Because social networking and interviewing behavior have attracted significant research attention, we describe findings with respect to these two job search methods in greater detail. We provide examples of the relevance of context to job search (i.e., the job seeker's geographical region, country, and culture; the economy; the job seeker's current or past employment situation; and employer behaviors and preferences) and review research on bias in the job search. Finally, we survey work on job search interventions and conclude with an overview of pressing job search issues in need of future research.

Interventions are implemented with greater fidelity when their core intent is made explicit. The core intent of this intervention was to increase access to higher order learning opportunities for students with learning disabilities or difficulties in mathematics through use of research and practice from the fields of special education and mathematics education. Four steps undertaken in the development of a Tier II fraction-based mathematics intervention designed to improve the conceptual understanding of students with learning disabilities or difficulties are described in this article: (a) articulation of a logic model, (b) delineation of intervention components, (c) analysis of reliability data related to implementation fidelity, and (d) pilot testing to measure implementation fidelity and student outcomes. Results of the pilot study demonstrated no significant effect for the component of technology; however, significant pre–post differences were found in the performance of all groups on their conceptual understanding of fractions as numbers.

Video games are a very popular form of entertainment media and have been the subject of much debate since their meteoric rise to popularity in the 1980s. Similar to the criticisms leveraged against other forms of media, video games have often been scrutinized for their potential to negatively influence those who play them. However, since the beginning of the 21st century, many new genres of video games have emerged and as a result, both public dialogue and research attention have shifted more toward understanding how certain games can be used for prosocial purposes. Exercise-based and active video games (AVGs) are a type of game which requires players to get up and move instead of simply sitting in front of the TV and pushing buttons. These types of games have received a lot of popular press and scholarly attention due to the fact that they encourage movement and may be used as a health intervention tool, especially to combat problems like obesity and overweight. Even though there has been significant research attention focused on the potential health benefits of playing these types of games, there is still much work to be done. While researchers have advanced a general understanding of why certain AVGs are effective or ineffective, there needs to be a greater emphasis on understanding the process by which these games can be motivating and influential. Shedding light on what makes AVGs potentially effective health management and intervention tools will not only be important for motivating people to become more active, but may also help inform research which focuses on how video games may be used in the health domain more generally.

Important Research Problem

Abstract Quantum systems provide a new way of conducting computations based on the so-called qubits. Due to the potential for significant speed-ups, this field received significant research attention in recent years. The Clifford+T library is a very promising and popular gate library for these kinds of computations. Unlike other libraries considered so far, it consists of only a small number of gates for all of which robust, fault-tolerant realizations are known for many technologies that seem to be promising for large-scale quantum computing. As a consequence, (logic) synthesis of Clifford+T quantum circuits became an important research problem. However, previous work in this area has several drawbacks: Corresponding approaches are either only applicable to very small quantum systems or lead to circuits that are far from being optimal. The latter is mainly caused by the fact that current synthesis realizes the desired circuit by a local, i.e., column-wise, consideration of the underlying unitary transformation matrix to be synthesized. In this paper, we analyze the conceptual drawbacks of this approach and propose to overcome them by taking a global view of the matrices and perform a separation of concerns regarding individual synthesis steps. We precisely describe a corresponding algorithm as well as its efficient implementation on top of decision diagrams. Experimental results confirm the resulting benefits and show improvements of up to several orders of magnitudes in costs compared to previous work.

The Cu/Al dissimilar joint, welded by high-power ultrasonic welding technology, is still facing challenges despite the significant research attention it has attracted. In this work, the microstructure and mechanical properties of resistance heat-assisted high-power ultrasonic welding of Cu/Al are investigated, in order to obtain high-quality joints. The intermetallic compound (IMC) at the interface of hybrid welding is primarily composed of Al2Cu, and the additional resistance of heat reduces the thickness of this brittle IMC layer. The average shear stress for the joint prepared by hybrid welding is ~97 MPa, which is higher compared to the joint strength without resistance heat (90 MPa). Moreover, the duration of the hybrid welding process is shorter. Finally, the fracture of the hybrid weld is found to be a brittle–ductile hybrid mode.

Cargo Transportation

Airports are important air transportation facilities, providing cargo transportation, aircraft takeoff and landing, and passenger services. Trade liberalization and globalization along with shifting economies and trading focuses have led to the rapid growth of airline and cargo transportation in Asia-Pacific regions. Therefore, Asian countries are constantly expanding and improving their airport facilities. Thus, improving and measuring airline service quality has attracted significant research attention in recent years. The Chinese Government has also actively promoted low-cost tourism, although competition in low-cost carrier markets was bound to be fierce. This not only promoted tourism industries but also attracted many foreign visitors to taking low-cost carriers to China for sightseeing. With international oil prices and regional economy issues, full-service carriers face considerable operational pressure on cost and competition. This study used the fuzzy delphi and decision making trial and evaluation laboratory methods to explore and analyze key factors for passengers choosing low-cost airlines. We considered passengers using U Airlines to travel from Shanghai to Taiwan (Taoyuan, Kaohsiung Far) and investigated service quality, low-price strategies, switching costs, and boarding willingness factors. We found that boarding willingness and service quality were strongly relevant to passenger satisfaction. Service quality should be prioritized, followed by switching cost, to enhance passenger boarding willingness. Low-cost regional airlines need to prioritize improving service quality empathy and service quality responsiveness with limited resources. Performance indicators such as willingness, service quality assurance, and service quality reliability showed significant benefits for overall service performance and passenger boarding willingness.

Feedback Cycle

Video annotation software (VAS) programs, such as GoReact, allow users to provide synchronized feedback in a video recording. This report examines the integration of VAS into a student teaching internship at a Historically Black University during a three-semester period. Through this research, the authors determine the effectiveness of the VAS feedback cycle in terms of support for the learning and development of teacher candidates. The research evidence pinpoints the need for extensive training by all participants and for accessible technical support. Moreover, the research demonstrates a lack of value and understanding of the importance of the VAS feedback cycle from all the participants and stakeholders. Finally, the research recommends that, in order to use the VAS feedback cycle appropriately, all the participants must be trained in the system and in the pedagogy and value of VAS learning systems.
