Unfamiliar accent and lack of fluency in English language have been identified as key challenges for international faculty in USA universities and colleges, particularly non-native English speakers and writers. These can have negative effects such as loss of interest in a given course, and possibly lead to poor performance. Currently, there are little or no evidence that most USA universities have...
Traditional STEM education models in electrical engineering and computer science rely on structured classes, laboratories, and textbooks to transfer key concepts. Even though this process meets most of the ABET objectives, it does not respond well to current workforce needs that require widely accessible programs that will provide a large pool of graduates with STEM backgrounds, analytical and programming...
It is widely accepted that successful engineers need to write accurately and effectively about complex topics. As engineers gain professional status and increased job responsibilities, they write more often and with higher stakes. Those who cannot express themselves well using standard English face a major hurdle to their long-term professional success. Alarmingly, many of today's students come to...
The aim of this study is to investigate the effect of peer scaffolding on students' reasoning skills and learning performance in online collaborative learning. This study has been carried out for 6 weeks and has involved 60 secondary school students taking Information and Communication Technology (ICT) subject. The independent variable of this study is the six types of scaffolding given by peers,...
We report on the second design cycle of Acropolis, a social computing platform that allows citizens to build and share their own narratives about long-running news stories. A key goal of this research project is to explore the following design opportunity: how can we re-design news stories in order to engage citizens in their reading and curation? In this paper, we describe an asymmetric collaboration...
Collaborative filtering methods suffer from a data sparsity problem, which indicates that the accuracy of recommendation decreases when the user-item matrix used in recommendation is sparse. To alleviate the data sparsity problem, researches on data imputation have been done. In particular, the zero-injection method, which finds uninteresting items and imputes zero values to those items for collaborative...
Researchers create larger networks of contacts through research collaboration, known as collaboration networks of researchers. In order to promote and to have effective collaboration among researchers, the collaboration patterns need to be accessed and analysed to elevate research and publication (R&P) performance. However, the collaboration patterns have not been accessed in the context of Universiti...
In software development application lifecycle management (ALM) systems are used to support the development process. As these products are tailored for best fitting the applied programs and their actual usage is diverse. Often, this means that products of different vendors are applied, which reduce the reachability between different artefacts and the overall consistency of the system. In this paper...
Recently, dictionary learning based sparse representation algorithm has been widely adopted and achieved satisfying performance in image classification. However, sparse representation based classification (SRC) as well as collaborative representation based classification (CRC) always result in high residual error due to their basic assumption that considers training samples as dictionary directly...
Adaptive Collaboration (AC) has been proven and verified to be a promising methodology to conduct collaboration. AC follows an iterative and dynamic process that includes phases of role negotiation, agent evaluation, role assignment, role playing, and role transfer. However, AC is complex, and the benefits of AC are not easily observed. In particular, the benefits must be obtained through complicated...
The advantage of using collaborative brain-computer interfaces in improving human response in visual target recognition tests was investigated. We used a public EEG dataset created from recordings made using a 32-channel EEG system by Delorme et al. (2004) to compare the classification accuracy using one, two, and three EEG signal sets from different subjects. Fourteen participants performed a go/no-go...
DBpia is the largest digital-bibliography service provider in Korea. It provides several convenience functions for researchers. DBpia users (i.e., researchers) can search for papers via several search routes such as publications, publishers, authors, and keywords. Although the researchers can exploit the search functions, they may still have a number of search results as candidate papers to read....
In this study, a new academic event recommendation method is proposed. This method analyzes author interactions, academic event attendance records, research related, and textual descriptions from attended academic events to measure interaction strength between authors. Experiments on the DBLP dataset and Wiki Calls for Papers (WikiCFP) showed that the proposed method is helpful in improving the accuracy...
Emergency command and control centers (CC) are integrated facilities to assist and handle crisis situations. In these CCs, operators suffer both with information shortage and overload. This paper focuses on the information overload problem. Operators often do not have adequate access to information that may be relevant in the decision-making process. In many CC centers, information is stored without...
In the real-world, there are many criteria to evaluate agents on roles, which are an important factor affecting the result of the group role assignment (GRA). To obtain a satisfied assignment, we need to select an appropriate evaluation method. This paper points out the key issues of the related concepts, formalizes the problem of GRA based on multiple criteria (GRA-MC), investigates three algorithms...
A comprehensive evaluation model of enterprise's partner selection on UIC is established by use of Analytical hierarchical process (AHP) and Grey Fuzzy Evaluation Method. The evaluation index system is built through literature review and expert interview, and then the weight of each index is determined by AHP and the reasonable conversion from qualitative to quantitative is acquired through the application...
In situations when several participants collaborate with each other, it is desirable to come up with a fair way to divide the resulting gain between the participants. Such a fair way was proposed by John von Neumann and Oscar Morgenstern, fathers of the modern game theory. However, in some situations, the von Neumann-Morgenstern solution does not exist. To cover such situations, we propose to use...
In the paper we intend to show in detail how the issue of the transition from the ‘Pisces’ into the so-called ‘Aquarius’ "World age" moves through the world view of the two major minds', Wolfgang Pauli and Carl G. Jung's world view of special scientific interpreting "Psyche and Nature" through the reinterpreted symbols of astrology in a "synchronistic way" in particular...
Educational recommendation is often pursued in environments where there is significant content knowledge of each item. For example, a recommender might choose appropriate learning modules in a tutoring system. In such cases, content-based recommendation can be very powerful. Our work examines recommendation of educational experiences in an informal learning environment. In this domain, content knowledge...
