- The most widely used method in recommendation systems is collaborative filtering, of which, a critical step is to analyze a user's preferences and make recommendations of products or services based on similarity analysis with other users' ratings. However, collaborative filtering is less usable for recommendation facing the 'cold start' problem, i.e. few comments being given to products or services. To tackle this problem, we propose an improved method that combines collaborative filtering and data classification. We use hotel recommendation data to test the proposed method. The accuracy of the recommendation is determined by the rankings. Evaluations regarding the accuracies of Top-3 and Top-10 recommendation lists using the 10-fold cross-validation method and ROC curves are conducted. The results show that the Top-3 hotel recommendation list proposed by the combined method has the superiority of the recommendation performance than the Top-10 list under the cold start condition in most of the times.

- Purpose - The concept of Triple Helix relates to collaboration between universities, governments and industry. Such collaboration can take different forms in different countries. This paper examines collaboration between universities and industry in China, specifically in the city of Hefei in Anhui province, one of the most rapidly developing regions in the country. In so doing, it seeks to address the research question: How does industry collaborate with universities in order to acquire commercialized knowledge? Design/ Methodology/ Approach - The study is qualitative, based on interviews with experts in R & D, and Intellectual Property Rights from high-tech companies based in Hefei. We analyzed our findings using a conceptual framework that focuses on Knowledge Transfer and Innovation Diffusion (Liyanage et al, 2012). Our study describes and discusses the entire process, from an initial awareness of new knowledge to its eventual acquisition.Findings and implications - We conclude that Chinese high-tech companies design comprehensive strategies for the acquisition of knowledge generated from external sources. These strategies are based on local, provincial and state government industrial policies that aim to support collaboration with universities and implement external knowledge in existing systems.Originality - Commercialized knowledge put into practice by industries for their own innovation and commercial purposes.Limitation - We interviewed industrial experts from three high-tech companies in the city of Hefei, which is located in an industrial area of Anhui province.

- Introduction. This paper focuses on knowledge generation and the way in which it is transferred from universities to industry. Most well reputed universities have several departments and university-run enterprises that engage in research. The purpose of these research units is to help universities provide breakthrough innovation through the generation of new knowledge.Problem Statement. For this we chose to study China's University Technology Transfer Offices (UTTOs) to gather concrete evidence of university knowledge generation for commercial use in industry. The objective of this study is get indepth information about the role of UTTOs in the transfer of such knowledge.Purpose. The generation of new knowledge contributes to the field of science and technology; in turn, industry can use this knowledge to produce new innovative products or improve existing ones. This study aims to identify the process of knowledge transfer from universities to industry in China.Materials and Methods. Our study was carried out as a qualitative case study in the Anhui province of China. Data was mainly collected through semi-structured interviews with technology transfer experts working in technology transfer offices. Collected data were analyzed using a knowledge transfer model with six phases: 1) awareness, 2) acquisition, 3) transformation, 4) association, 5) application, and 6) feedback.Results. In China, universities and their research groups dominate in the generation and commercialization of research results, with UTTOs acting as technology bridges between the two parties, as well as providing legal and business services.Conclusions. This paper contributes by offering a detailed description of the knowledge transfer process and specifically the role and activities of UTTOs. This research also helps Chinese and international researchers currently carrying out research on the technology transfer process in China.

- After the introduction of information technology (IT), the government needs to take the initiative to start IT projects for the automation of government process to the citizen. Statistics show that a high number of government IT projects fail and only 15 percent e-government projects are successful. In this study, we will answer this research question, what are the reasons for failure of IT projects in the government sector organization in Pakistan and how to overcome these issues? This research was conducted through a literature review, 20 articles from journals and conferences were selected through keywords for the period of ten years from 2003 to 2013. For suggestions, we have followed the same structured search procedure. We found and select articles with our keywords, after reading abstract and conclusion. Our study has described four factors for the failure of IT projects in government sector organizations in Pakistan. These factors are Technology, Management, Politics and Finance. The technology factor can be reduced by providing latest ICT infrastructure with an expert to run and maintain it. Management issues can be resolved by hiring an experienced, skilled and highly motivated project manager to complete a project successfully. Government should make new laws and regulations to help the implementation of these projects and bureaucracy should eliminate any power struggle during and after the implementation. The budget should be allocated before the start of the project to complete it on time. Our research study has provided guidelines to policy makers for automation of government organizations in Pakistan. By considering these suggestions, successful government projects can be achieved.

- The concept of Triple Helix relates to collaboration between universities, governments and industry. Such collaboration can take different forms in different countries. This paper describes collaboration between universities and government in China, specifically in the city of Hefei in Anhui province, one of the most rapidly developing regions in the country. The research question is: How can bi-lateral research collaboration be a source of knowledge generation and commercialization for use in industry?The study is qualitative, involving individual and group interviews with university team leaders and team members from successful projects. Government representatives in China were also interviewed. We used the SECI knowledge creation method to analyze the findings. We also describe the collaboration process from idea and application through to review, funding, realization and commercialization. Our study shows that the government in China plays a dominant role in the process of knowledge creation and commercialization. We conclude that collaboration is a source of new knowledge generation and that the government plays a key role by funding universities and creating a research environment that meets the policy requirements of industry today. In particular, we show that universities and their research groups use resources, such as skilled manpower, laboratories and equipment, to accomplish tasks within a set timeframe.

A framework for ICT-based knowledge sharing in sustainable rural development : the case of Gilgit-Baltistan, Pakistan
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Some 50% of the people in the world live in rural areas, often under harsh conditions and in poverty. The need for knowledge of how to improve living conditions is well documented. In response to this need, new knowledge of how to improve living conditions in rural areas and elsewhere is continuously being developed by researchers and practitioners around the world. People in rural areas, in particular, would certainly benefit from being able to share relevant knowledge with each other, as well as with stakeholders (e.g. researchers) and other organizations (e.g. NGOs). Central to knowledge management is the idea of knowledge sharing. This study is based on the assumption that knowledge management can support sustainable development in rural and remote regions. It aims to present a framework for knowledge management in sustainable rural development, and an inventory of existing frameworks for that. The study is interpretive, with interviews as the primary source for the inventory of stakeholders, knowledge categories and Information and Communications Technology (ICT) infrastructure. For the inventory of frameworks, a literature study was carried out. The result is a categorization of the stakeholders who act as producers and beneficiaries of explicit and indigenous development knowledge. Stakeholders are local government, local population, academia, NGOs, civil society and donor agencies. Furthermore, the study presents a categorization of the development knowledge produced by the stakeholders together with specifications for the existing ICT infrastructure. Rural development categories found are research, funding, agriculture, ICT, gender, institutional development, local infrastructure development, and marketing & enterprise. Finally, a compiled framework is presented, and it is based on ten existing frameworks for rural development that were found in the literature study, and the empirical findings of the Gilgit-Baltistan case. Our proposed framework is divided in four levels where level one consists of the identified stakeholders, level two consists of rural development categories, level three of the knowledge management system and level four of sustainable rural development based on the levels below. In the proposed framework we claim that the sustainability of rural development can be achieved through a knowledge society in which knowledge of the rural development process is shared among all relevant stakeholders.

- Flexible study pace distant courses provide opportunities for students with disabilities to attend courses in higher educations as opposed to campus courses with fixed schedules. At least that is what we believe. This study investigates how mentally disabled students perceive taking distant courses with flexible pace and also how their teachers perceive opportunities and challenges. Flexible pace means here distant courses where students can start when they like and keep the pace they prefer. The courses in question are part of a two year program of eService Development at Dalarna University in Sweden. The program was launched in 2006 and admits ca 50-80 students each semester. Many of the students are unable to take campus courses of various reasons such as living far from universities, working daytime, etc. We sent out questionnaires to students with disabilities and to teachers asking them semi structured questions about perceived challenges and opportunities regarding the studies. The students had mental disabilities such as Dyslexia, ADHD, Asperger syndrome, Chronic Fatigue Syndrome, and Social Phobia. The answers have been analyzed qualitatively by categorizing the answers firstly in groups of challenges and opportunities and further on in sub categories. Our finding shows that the flexible aspect is especially important to students as it gives them the opportunity to adjust their studying practices to their disabilities. Our conclusions are that the flexible study pace approach (FreeStartFreePace) is suitable for students with nonlinear work. It is also useful for students with mental disabilities who could have a problem adapting to schedules and conforming procedures.

Flipped classroom and learning strategies
- 2015
-
Ingår i: Proceedings of 14<sup>th</sup> European Conference on e-Learning. - Reading, UK : Academic Conferences Publishing. ; , s. 41-49
-
Konferensbidrag (refereegranskat)abstract
- This paper seeks to answer the research question "How does the flipped classroom affect students’ learning strategies?" In e-learning research, several studies have focused on how students and teachers perceive the flipped classroom approach. In general, these studies have reported pleasing results. Nonetheless, few, if any, studies have attempted to find out the potential effects of the flipped classroom approach on how students learn.This study was based on two cases: 1) a business modelling course and 2) a research methodology course. In both cases, participating students were from information systems courses at Dalarna University in Sweden. Recorded lectures replaced regular lectures. The recorded lectures were followed by seminars that focused on the learning content of each lecture in various ways.Three weeks after the final seminar, we arranged for two focus group interviews to take place in each course, with 8 to 10 students participating in each group. We asked open questions on how the students thought they had been affected and more dedicated questions that were generated from a literature study on the effects of flipped classroom courses. These questions dealt with issues about mobility, the potential for repeating lectures, formative feedback, the role of seminars, responsibility, empowerment, lectures before seminars, and any problems encountered.Our results show that, in general, students thought differently about learning after the courses in relation to more traditional approaches, especially regarding the need to be more active. Most students enjoyed the mobility aspect and the accessibility of recorded lectures, although a few claimed it demanded a more disciplined attitude. Most students also expressed a feeling of increased activity and responsibility when participating in seminars. Some even felt empowered because they could influence seminar content. The length of and possibility to navigate in recorded lectures was also considered important. The arrangement of the seminar rooms should promote face-to-face discussions. Finally, the types of questions and tasks were found to affect the outcomes of the seminars.The overall conclusion with regard to students’ learning strategies is that to be an active, responsible, empowered, and critical student you have to be an informed student with possibilities and mandate to influence how, where and when to learn and be able to receive continuous feedback during the learning process. Flipped classroom can support such learning.

Modeling and illustrating requirement prioritization in public e-service development from a value-based perspective
- 2015

Tidskriftsartikel (refereegranskat)abstract
- A major problem in e-service development is the prioritization of the requirements of different stakeholders. The main stakeholders are governments and their citizens, all of whom have different and sometimes conflicting requirements. In this paper, the prioritization problem is addressed by combining a value-based approach with an illustration technique. This paper examines the following research question: How can multiple stakeholder requirements be illustrated from a value-based perspective in order to be prioritizable? We used an e-service development case taken from a Swedish municipality to elaborate on our approach. Our contributions are: 1) a model of the relevant domains for requirement prioritization for government, citizens, technology, finances and laws and regulations; and 2) a requirement fulfillment analysis tool (RFA) that consists of a requirement-goal-value matrix (RGV), and a calculation and illustration module (CIM). The model reduces cognitive load, helps developers to focus on value fulfillment in e-service development and supports them in the formulation of requirements. It also offers an input to public policy makers, should they aim to target values in the design of e-services.

Second order interactive end user development appropriation in the public sector : Application development using spreadsheet programs
- 2018

Tidskriftsartikel (refereegranskat)abstract
- This paper seeks to respond to the research question: How does appropriation take place in the public sector in the development of end user applications by civil servants? Appropriation is defined as taking advantage of opportunities related to the development and use of applications, when the developer has in-depth knowledge of the problem domain and is also the primary user of the application. Our results showed that public servants who have deep problem domain knowledge can take advantage of end user tools (e.g. spreadsheet programs) in the problem- solving process to solve vaguely defined problems. Appropriation is manifested in the continuous development of various ICT applications. In this paper, we differentiate between first- and second-order appropriation. First-order appropriation takes place when the potential of the development tool is appropriated by the end user. Second-order appropriation takes place when an application is continuously developed and refined in parallel with the end user’s learning process and the development of organizational requirements.

- Socratic questioning stresses the importance of questioning for learning. Flipped Classroom pedagogy generates a need for effective questions and tasks in order to promote active learning. This paper describes a project aimed at finding out how different kinds of questions and tasks support students’ learning in a flipped classroom context. In this study, during the flipped courses, both the questions and tasks were distributed together with video recordings. Answers and solutions were presented and discussed in seminars, with approximately 10 participating students in each seminar. Information Systems students from three flipped classroom courses at three different levels were interviewed in focus groups about their perceptions of how different kinds of questions and tasks supported their learning process. The selected courses were organized differently, with various kinds of questions and tasks. Course one included open questions that were answered and presented at the seminar. Students also solved a task and presented the solution to the group. Course two included open questions and a task. Answers and solutions were discussed at the seminars where students also reviewed each other’s answers and solutions. Course three included online single- and multiple choice questions with real-time feedback. Answers were discussed at the seminar, with the focus on any misconceptions. In this paper we categorized the questions in accordance with Wilson (2016) as factual, convergent, divergent, evaluative, or a combination of these. In all, we found that any comprehensible question that initiates a dialogue, preferably with a set of Socratic questions, is perceived as promoting learning. This is why seminars that allow such questions and discussion are effective. We found no differences between the different kinds of Socratic questions. They were seen to promote learning so long as they made students reflect and problematize the questions. To conclude, we found that questions and tasks promote learning when they are answered and solved in a process that is characterized by comprehensibility, variation, repetition and activity.

Tidskriftsartikel (refereegranskat)abstract
- Sustainable development is a major concern all over the world. Indeed, it is required in every domain of life, including that of government. E-services are widely acknowledged for the contribution they make to e-government. The research question raised in this study is: What is the existing status of e-service sustainability research? The research method used is a literature study that adopts a concept-centric approach. Literature was collected from high-ranking IS journals and relevant databases. Selected literature was then analyzed using the twin concepts of e-service sustainability itself and the enabler (secondary) effects of sustainable e-services. The Triple Bottom Line’s model was used to further categorize the findings using economic, environmental, and social sustainability concepts. Finally, the selected papers were analyzed in terms of research approach and topic. The results of the study revealed a lack of research into e-service sustainability. By way of contrast, it revealed 20 articles that cover the enabler effect. Existing research is related to economic and social dimensions, with the most common topic being related to user satisfaction.

Where do e-Government strategies take the Nordic nations?
- 2016
-
Ingår i: Electronic Journal of e-Government. - 1479-439X. ; 14:1, s. 2-16
-
Tidskriftsartikel (refereegranskat)abstract
- An effective strategy is critical for the successful development of e-Government. The leading nations in the e-Government rankings include Sweden, Norway, Denmark and Finland. Their leading role makes them interesting to study when looking for reasons to successful e-Government. The purpose of this research paper is to describe the e-Government development strategies of Nordic countries, which rank highly on the international stage. In particular it aims to study the foci of these strategies. The approach is a document study of the e-Government development strategies of Sweden, Denmark, Norway and Finland was carried out using a qualitative content analysis inductive method. The results show that the major focus of Nordic e-Government strategies is on public sector reforms. Other focus areas include economic reforms and, to a lesser extent, e-Democracy efforts. Sweden, Finland and Norway have set ambitious policy goals in order to achieve global leadership in e-Government development. In response to the question posed by this paper’s title, we can say that Nordic e-Government strategies, except for Norway, focus more on reforming public sector services than on economic reforms. E-Democracy reforms are hardly focused on at all.Practical implications: Public sector policy makers can relate their policy foci to some of the more successful e-Government countries in the world. Research implications/originality is that this paper can apart from the findings also provide a means on how to identify the actual foci of a country’s e-Government policy.
