A co-writing development approach to wikis: Pedagogical issues and implications
2011
Published version of a paper from the journal: World Academy of Science, Engineering and Technology. Also available from the publisher: http://www.waset.org/journals/waset/v77/v77-107.pdf Wikis are promoted as collaborative writing tools that allow students to transform a text into a collective document by information sharing and group reflection. However, despite the promising collaborative capabilities of wikis, their pedagogical value regarding collaborative writing is still questionable. Wiki alone cannot make collaborative writing happen, and students do not automatically become more active, participate, and collaborate with others when they use wikis. To foster collaborative writing a…
Research on Vocabulary Sizes and Codebook Universality
2014
Published version of an article in the journal: Abstract and Applied Analysis. Also available from the publisher at: http://dx.doi.org/10.1155/2014/697245 Open Access Codebook is an effective image representation method. By clustering in local image descriptors, a codebook is shown to be a distinctive image feature and widely applied in object classification. In almost all existing works on codebooks, the building of the visual vocabulary follows a basic routine, that is, extracting local image descriptors and clustering with a user-designated number of clusters. The problem with this routine lies in that building a codebook for each single dataset is not efficient. In order to deal with th…
Semi-supervised classification using tree-based self-organizing maps
2011
Published version of an article from the following onference prodeedings: AI 2011: Advances in Artificial Intelligence. Also available from the publisher on SpringerLink: http://dx.doi.org/10.1007/978-3-642-25832-9_3 This paper presents a classifier which uses a tree-based Neural Network (NN), and uses both, unlabeled and labeled instances. First, we learn the structure of the data distribution in an unsupervised manner. After convergence, and once labeled data become available, our strategy tags each of the clusters according to the evidence provided by the instances. Unlike other neighborhood-based schemes, our classifier uses only a small set of representatives whose cardinality can be m…
Virtual PhD courses – A new mode of PhD education?
2012
Published version of an article from the proceedings of the NOKOBIT conference. Also available from Tapir:http://www.tapironline.no/fil/vis/1029 This paper presents experiences from a joint virtual PhD course for doctoral students at a Norwegian and a US university. Based on an experiential learning approach, the course focused on practices for virtual research collaboration. Through six synchronous online sessions, interspersed with interaction in sub-teams, the participants worked on developing a joint conference publication. This gave the PhD students first-hand experience with working in a virtual research team. Based on our analysis of the experiences from the course, we discuss challe…
Engineering students approaching the mathematics textbook as a potential learning tool – opportunities and constraints
2016
Doktorgradsavhandling It is usually assumed that the students at tertiary level work intensively and individually with the new mathematical concepts (Wood, 2001). In this context the mathematics textbook might be an important learning tool. This thesis addresses the issue of what factors might influence the role of the mathematics textbook as a learning tool. The study is situated in the context of the basic mathematics course taken by first-year engineering students. A brief pilot study indicated that a majority of the students preferred using lecture notes rather than the textbook although in the beginning of the semester they perceived the textbook as being important when learning mathem…
Modeling a teacher in a tutorial-like system using Learning Automata
2012
Published version of a chapter in the book: Transactions on Computational Collective Intelligence VIII. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-34645-3_2 The goal of this paper is to present a novel approach to model the behavior of a Teacher in a Tutorial- like system. In this model, the Teacher is capable of presenting teaching material from a Socratic-type Domain model via multiple-choice questions. Since this knowledge is stored in the Domain model in chapters with different levels of complexity, the Teacher is able to present learning material of varying degrees of difficulty to the Students. In our model, we propose that the Teacher will be able to as…
The Finding and Dynamic Detection of Opinion Leaders in Social Network
2014
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2014/328407 It is valuable for the real world to find the opinion leaders. Because different data sources usually have different characteristics, there does not exist a standard algorithm to find and detect the opinion leaders in different data sources. Every data source has its own structural characteristics, and also has its own detection algorithm to find the opinion leaders. Experimental results show the opinion leaders and theirs characteristics can be found among the comments from the Weibo social network of China, which is like Facebook…
Retail Innovativeness
2014
Retailers have to operate in highly competitive environments, where innovation may become a source of sustainable competitive advantage. This chapter aims at exploring the relationship between retail innovativeness and the level of technological advancement as well as the ICT solutions implemented by store chains of four retail activities (e.g. grocery, textile, electronics, and furniture and decoration). In addition to this, the authors test the existence of significant differences in consumer perceptions and behavioral intentions between retailers perceived as high innovators and those considered low innovators. As a result, differences in consumer behaviour are found between high and low…
Teaching networking: an interpersonal communication competence perspective
2015
Modern working life calls for competences that enable people to be creative, innovative and effective. Studies looking at contemporary enterprises and organisations such as businesses and schools have shown that many of the qualifications that graduating students would need, including informal learning (see Gielen, Hoeve & Nieuwenhuis 2003), innovativeness (e.g. Moolenaar & Sleegers 2010; Obstfeld 2005) and creativity (e.g. Burt 2004; Perry-Smith & Shalley 2003), are associated with interpersonal relationships and social networks. According to a report on the national career survey (EK 2011a), effective networking is dependent on social skills such as the ability to establish contacts in mu…
Diversity and Social Interaction at Work
2019
Today’s workplaces are characterized by interactions among people with diverse backgrounds. These interactions may occur face-to-face or in technology-mediated settings; as interpersonal exchanges between co-workers, supervisors, and subordinates or between business partners and clients; in small groups and teams or as one-off encounters with customers. The persons engaged in these interactions jointly strive for the shared goals of their organization though they may come from different countries, speak different first languages, or identify with different ethnic, gender, or age groups. This chapter explores the role of diversity in different workplace contexts and situations. First, we unp…
