  • Compact City Planning and Development : Emerging Practices and Strategies for Achieving the Goals of Sustainable Development
  • 2020
  • Ingår i: Development in the Built Environment. - : Elsevier BV. - 2666-1659. ; 4
  • Tidskriftsartikel (refereegranskat)abstract
    • Compact city planning and development has, over the last 30 years or so, been the hegemonic response to the challenges of sustainable development. Global and local policies promote the compact city model due to the positive outcomes of its design principles and strategics as to achieving sustainable cities in terms of their environmental, economic, and social goals. The aim of this paper is to examine how the compact city model is practiced and justified in urban planning and development with respect to the three dimensions of sustainability, and whether any kind of practical progress has been made in this regard. To illuminate the phenomenon of the compact city, a descriptive case study is adopted as a qualitative research methodology where the empirical basis is mainly formed by urban plans in two Swedish cities: Gothenburg and Helsingborg, in combination with qualitative interview data, secondary data, and scientific literature. This study shows that compactness, density, diversity, mixed land use, sustainable transportation, and green space are the prevalent design principles and strategies of compact city planning and development, with the latter being contextually linked to the concept of green structure, an institutional setup under which the two Swedish cities operate. Moreover, at the core of the compact city model is the clear synergy between the underlying principles and strategies in terms of their cooperation to produce combined effects greater than the sum of their separate effects with respect to the benefits of sustainability as regards its tripartite value. Further, this study demonstrates that the compact city model as practiced by the two cities is justified by its ability to contribute to the environmental, economic, and social goals of sustainable development. However, the economic goals dominate over the environmental and social goals, notwithstanding the claim about the three dimensions of sustainability being equally important at the discursive level. Nevertheless, new planning measures are being implemented to address the relevant environmental and social issues towards balancing the three goals of sustainability and thus strengthening their influence over urban development practices.

  • A Combined Framework for Development of Business Process Support Systems
  • 2009
  • Ingår i: The Practice of Enterprise Modeling. - Berlin, Heidelberg : Springer Berlin/Heidelberg. - 9783642053528 - 9783642053511 ; , s. 115-129
  • Konferensbidrag (refereegranskat)abstract
    • In this paper, a combined modeling framework consisting of goal modeling, process modeling and business process characterizing modeling is presented. The framework is made to guide both business experts and model developers during the life cycle of a modeling-based project development. We consider a business process characterizing model (BPCM) as a starting point for developing an IT system. Then, the start of goal models and process models can be derived from a BPCM model. Process models are then used as inputs for deriving a candidate IT system. A development methodology to guide the development of process models from business process characterizing model is proposed. Furthermore, the development methodology is illustrated by an exemplar in the field of scientific conference organization.

  • Ingår i: The international journal of information and learning technology. - : Emerald Group Publishing Limited. - 2056-4880 .- 2056-4899. ; 32:1, s. 32-44
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose:€“ The purpose of this paper is to develop a mobile service, based on anonymous location-based data, to help students find available reading rooms on a university campus. To evaluate this mobile service, both a usability test and a technology acceptance test were carried out.Design/methodology/approach:€“ The research followed a design science approach, including developing a prototype and evaluating the developed prototype.Findings:€“ The results from the usability test indicated good usability of the developed mobile service. The results from the technology acceptance test demonstrated students’ intention to use this mobile service. Most respondents indicated that they would like to use this mobile service to find available reading rooms when they are on campus.Research limitations/implications:€“ The results imply that there are other contexts where anonymous location-based data are also useful. A similar mobile service can be developed for other contexts, such as, hospital complexes, shopping malls, and airports.Originality/value:€“ To the authors best knowledge, the authors have not found any mobile services aiming at counting the density of people residing in a room by using anonymous user location-based data on a university campus. This research fills this gap by developing the mobile service, called finding reading rooms.

  • A Repository Architecture for Business Process Characterizing Model
  • 2010
  • Ingår i: The Practice of Enterprise Modeling. - Berlin, Heidelberg : Springer Berlin/Heidelberg. - 9783642167829 - 9783642167812 ; , s. 162-176
  • Konferensbidrag (refereegranskat)abstract
    • In this paper, the Business Process Characterizing Model (BPCM) repository architecture is presented. The repository architecture follows a three-layer model composed of a presentation layer, a repository management layer and a storage layer. The objective of the architecture proposed here is to organize BPCM models in a manner that enable their reutilization, and some guidelines on how to use the BPCM repository are provided. Business users are expected to be able to benefit from the advanced functionalities provided by the BPCM repository. Furthermore, based on the evaluation of the BPCM repository by comparing it with some other process repositories, we find that the BPCM repository can offer most features other process repositories are able to provide with the exception of control flow.

  • An Empirical Test of the Mobile Services Acceptance Model
  • 2010
  • Ingår i: Proceedings of the 2010 Ninth International Conference on Mobile Business / 2010 Ninth Global Mobility Roundtable. - : IEEE Computer Society. - 9780769540849 ; , s. 168-175
  • Konferensbidrag (refereegranskat)abstract
    • This paper presents a mobile services acceptance model, which includes aspects of trust, contextual fit, and personal initiatives and characteristics in addition to perceived usefulness and perceived ease of use from the technology acceptance model (TAM). The proposed research model was empirically tested using data collected from a survey of 25 users of a mobile service called Mobile Student Information Systems (MSIS). The results reveal that the fitness of the acceptance model is quite good. Our findings indicate that personal initiatives and characteristics, trust, and perceived ease of use are key determinants for the users to adopt the mobile service. Context via its influence on perceived usefulness and perceived ease of use has an indirect affect on intention to use. Furthermore, a striking finding is the negative influence of perceived usefulness on intention to use.

  • 2012
  • Ingår i: International Journal of Information System Modeling and Design. - : IGI Global. - 1947-8186 .- 1947-8194. ; 3:1, s. 78-98
  • Tidskriftsartikel (refereegranskat)abstract
    • In this paper, a case study is used to evaluate the business process characterizing modeling (BPCM) language. The BPCM-framework is meant to guide both business stakeholders and model developers during model-based development. The focus of the approach is the use of BPCM as a starting point for capturing process knowledge when planning and developing information system support. Based on information within the BPCM models, goal models and process models can be developed and used for further development of the BPCM model. The approach in this paper is evaluated using a case study related to the arrangement of a conference series. Through the case study, the authors have confirmed the potential usability and usefulness of BPCM for early stage knowledge capture, getting input for further improvement of the approach.

  • Developing an instrument to measure the adoption of mobile services
  • 2011
  • Ingår i: International Journal of Mobile Information Systems. - : IOS Press. - 1574-017X .- 1875-905X. ; 7:1, s. 45-67
  • Tidskriftsartikel (refereegranskat)abstract
    • Currently, there is no standard instrument for measuring user adoption of mobile services. Based on the mobile service acceptance model, this paper reports on the development of a survey instrument designed to measure user perception on mobile services acceptance. A survey instrument was developed by using some existing scales from prior instruments and by creating additional items which might appear to fit the construct definitions. In addition, a pilot study was conducted by distributing the survey to 25 users of a mobile service called Mobile Student Information Systems. As a result, a survey instrument containing 22 items were retained. Furthermore, the results showed that the reliabilities of all the scales in the survey instrument were above the target acceptance level.

  • Differences in the Adoption of Smartphones Between Middle Aged Adults and Older Adults in China
  • 2015
  • Ingår i: Human Aspects of IT for the Aged Population. Design for Aging. - Cham : Springer Berlin/Heidelberg. - 9783319208923 - 9783319208916 ; , s. 451-462
  • Konferensbidrag (refereegranskat)abstract
    • This research aims to investigate the differences in the adoption of smartphones between middle aged adults and older adults in China. Based on a literature review from previous research, a research model with eight research hypotheses was developed by extending UTAUT with a consideration of observability and compatibility from IDT, and perceived enjoyment and price value. This research model was empirically examined using survey data from 196 middle aged adults and 146 older adults respectively from China. The findings indicated that the effects of perceived enjoyment, compatibility, and observability on users’ intention to use smartphones were significant, but no age differences between middle aged adults and older age adults were found to exist. Furthermore, the findings also identified age-related differences in the use and adoption of smartphones. The effects of performance expectancy and social influence on users’ intention to use smartphones were moderated by age, such that it was significant for older adults but insignificant for middle aged adults.

  • Explaining the Adoption of Mobile Information Services from a Cultural Perspective
  • 2011
  • Ingår i: Proceedings of the 2011 10th International Conference on Mobile Business. - : IEEE. - 9780769544342 ; , s. 243-252
  • Konferensbidrag (refereegranskat)abstract
    • Little research has been done to explore the adoption of mobile information services from a cultural perspective. This research is designed to study mobile information services adoption from a cultural perspective. Based on the three cultural dimensions (individualism/collectivism, uncertainty avoidance, and power distance), three research hypotheses are presented. To examine these hypotheses, an exploratory study is carried out with a mobile information service called eMSIS with both Norwegian students and Chinese students. Support was found for the three hypotheses. The findings indicate that the cultural dimensions play important roles in how mobile information services are used and adopted in two different cultural settings: the Norwegian culture and the Chinese culture. The results also highlight the relevance of the cultural dimensions (individualism/collectivism, uncertainty avoidance, and power distance) as the factors affecting the adoption of mobile information services.

  • Facilitating Business Process Development via a Process Characterizing Model
  • 2008
  • Ingår i: Proceedings of the 2008 International Symposium on Knowledge Acquisition and Modeling. - : IEEE Computer Society. - 9780769534886 ; , s. 239-245

    • Since the business environment is getting increasingly dynamic and complex, the relevant process models in the environment are becoming more complicated. This might easily confuse business experts and lead them to misunderstand the models. Business experts are expecting a simple way to communicate and collaborate with the model developers during business process development and use. Today, enterprise modelling is primarily focusing on goal modeling, resource modeling and process modeling. We propose an additional type of model, which is called business process characterizing model. This model can not only facilitate the efficient communication between business experts and model developers, but also offer an opportunity to handle emergent processes and capture dynamic knowledge and variability.

  • High level modeling and evaluation of multi-channel services
  • 2011
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The objective of this thesis is two-fold: (1) to study potential factors which influence users’ adoption of mobile services, and (2) to study important factors to construct a business process support system in a mobile setting. Consequently, this thesis consists of the following two research artifacts. Research artifact one is a mobile service acceptance model (MSAM) to access the adoption of mobile services. Research artifact two is a conceptual modeling language, called business process characterizing model (BPCM), which aims to support business process support system construction in a mobile setting.These two research artifacts are closely related. As described in the V-model, system requirements analysis and system acceptance are closely associated with each other. A business process support system in a specific domain in a mobile setting can be regarded as an advanced mobile system or service. Therefore, a good analysis of the system requirements and characteristics of the business processes involved in the domain in terms of BPCM is a key to the success of the adoption of the developed mobile system. Vice versa, some key factors which may influence the adoption of mobile system can also be taken into consideration when analyzing system requirements and characterizing relevant business processes at a high level.The MSAM is an extension of the Technology Acceptance Model (TAM), with a consideration of Trust, Context, and Personal Initiatives and Characteristics factors in addition to Perceived Ease of Use and Perceived Usefulness, to study the user adoption of mobile services. In addition, seven research hypotheses based on the research model were developed. Furthermore, in order to operationalize the research model, a survey instrument for measuring the adoption of mobile services was developed using the following steps: (1). Item Creation, (2). Item Refinement, (3). Item Testing. Based on 22 measurement items that were retained, the proposed research model was empirically tested using data collected from a questionnaire of 46 users of a mobile service called eMSIS. The findings revealed that Perceived Initiatives and Characteristics, Trust, Perceived Usefulness and Perceived Ease of Use are key determinants for the users to adopt the mobile service. Context via Perceived Usefulness and Perceived Ease of Use has an indirect effect on Intention to Use. The results indicated that the fitness of the research model was good and the seven research hypotheses were supported. The results and findings derived from this study will not only enhance our understanding of mobile services adoption, but also provide some insights to practitioners for designing and developing mobile services.Concerning the second research artifact, BPCM is proposed to describe the main characteristics and properties of a business process in a mobile setting. A BPCM metamodel is defined. Further, to store and query BPCM models, the BPCM repository architecture is presented. In addition, a combined modeling framework consisting of goal modeling, process modeling and business process characterizing modeling is depicted to support business process support system development. To assess the usability and quality of BPCM, a case study with regard to practical arrangements of a conference series was carried out. As for the BPCM language quality, we found that BPCM was able to address most process-oriented knowledge of a business domain with the exception of the control-flow and decomposition aspect. Also bundling of context aspects appeared to be useful. Moreover, the evaluation results also confirmed that the BPCM model could be used as a basis model for developing business process support systems. However, we saw some room for further improvements for BPCM, such as improved tool support for BPCM.The contributions of this thesis are summarized as follows.• An extended technology acceptance model, called mobile services acceptance model (MSAM), to be used to evaluate the users’ adoption of mobile services• A survey instrument to measure intention to use a mobile service• A modeling language, called Business Process Characterizing Model (BPCM) to support business process support systems development in a mobile setting• A BPCM repository architecture for storing and querying the BPCM model• An evaluation of the quality and usability of BPCM for early stage process modeling in a case study

  • Ingår i: International Journal of E-Business Research. - : IGI Global. - 1548-1131 .- 1548-114X. ; 10:3, s. 36-53
  • Tidskriftsartikel (refereegranskat)abstract
    • Along with the popularity of mobile devices and advances in wireless technology, mobile services have become more and more prevalent. To the best of knowledge, despite the potential importance of lifestyle, little research has been performed on the effect of various lifestyle factors on mobileservices diffusion, particularly in the Chinese context. This study examines the relationship between the lifestyles of Chinese consumers and the adoption of mobile services. Based on a sample of 313 respondents from the biggest city in central China, one can show that consumers with different lifestyles have different preferences related to a number of the identified mobile services. Furthermore, Chinese consumers are clustered into four lifestyle segments by two dimensions: the quality-awareness fashionable dimension and the economical dimension. The findings demonstrate that the quality-awareness fashionable dimension has stronger impact than the economical dimension toward the adoption of all the five types of mobile services.

    • Mobile games have become very popular in recent years in China. This research aims to investigate the potential factors that influence users’ intention to play mobile games. Through the employment of structural equation modeling technology, a research model by extending technology acceptance model (TAM) with flow experience and social norms was proposed. This research model was empirically evaluated using survey data collected from 388 users about their perceptions of mobile games. Eleven research hypotheses were proposed in the study. Eight research hypotheses were positively significant supported, while three research hypotheses were rejected in this study. The result indicates that attitude and flow experience explain about 75% of uses’ intention to playing mobile games. It was found that social norms do not have direct effect on the intention to play a mobile game. But it affects the attitude directly. In addition, flow experience, perceived ease of use and perceived usefulness all have direct effects on users’ attitude toward playing a mobile game, and the effect from flow experience is quite strong. Flow experience plays an important role in the adoption of mobile games according to the analytical results of our study.

  • Konferensbidrag (refereegranskat)abstract
    • Along with the popularity of mobile devices and advances in wireless technology, mobile services have become more and more prevalent. Although many analysts have predicted that mobile systems will become mainstream, the adoption of mobile services has been slower than expected. The main objective of this research is to study the influence of context on mobile services adoption. The importance of context towards mobile services adoption was explored by looking at two newly developed mobile services. The findings from the exploratory study demonstrate that context is a significant factor to affect people’s adoption of mobile services.

  • Model-driven Alignment : Linking Business Strategy with Information Systems
  • 2014
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Information technology (IT) is more pervasive than ever before, constituting a significant factor for performance and survival in the business arena. It is essential that IT within organizations understands what the Business needs in order to provide the necessary support and bring value, which is also true when IT is also the main value creator. Therefore, alignment between the Business and IT within organizations is an issue of great concern and it is still open for solvency both for business and IT executives and practitioners.This work is scoped to the alignment linkage between business strategy and information systems (IS), where business strategy typically constitutes the primary exponent of the Business and IS typically encapsulates the elements of IT sustaining an organization. Current approaches are either focused on detailed aspects of IS and treat business strategy abstractly or use distinct business strategy formulations (e.g. Value Chain) but deal with IS only partially. This is problematic because the abstract use of business strategy hinders traceability of strategic intentions and initiatives towards features/aspects of IS, which are aimed to actualize and support such intentions. Because approaches using distinct business strategy formulations are not relevant to all organizations and are limited only to the IS aspects addressed.Introducing a model-driven approach for the alignment linkage is aimed at addressing the outlined shortcomings. Following a design science research paradigm, the main artifact developed is the Unified Business Strategy Meta-Model (UBSMM), which is based on conceptualizing established business strategy formulations (e.g. Value Chain) and integrating them. UBSMM supports mappings to IS models used in organizations, such as IS requirements, enterprise models and enterprise architecture, and provides unambiguous utilization of business strategy for the alignment linkage.Contributions of this thesis are grounded both on the process of building UBSMM and mapping to IS models, as well as the artifact itself. Conceptualizing and integrating business strategy formulations provides a less ambiguous and unified view of strategic concepts. This limits variations in interpretation and reinforces mappings to IS models, which are defined based on inter-schema properties across models. Therefore, UBSMM can link business strategy to IS models enhancing their communication in a traceable manner, ergo, support alignment.

  • An Evaluation of an Enhanced Model Driven Approach for Computer Game Creation
  • 2015
  • Ingår i: Enterprise, Business-Process and Information Systems Modeling. - Cham : Springer Berlin/Heidelberg. - 9783319192376 - 9783319192369 ; , s. 499-508

    • Various game authoring tools have been used to ease the game creation. However, these pre-defined tools may not be suitable for some emerging domains. We proposed an approach (GCCT) to create tools for certain domains first, and then create games with these tools. GCCT is based on the Model Driven Development (MDD) approach which has been successfully applied in many domains to fulfill similar requirements. But MDD also has drawbacks and as a result, persons often have concerns to adopt MDD. To alleviate this, some enhancements were made in GCCT and a user survey was performed to probe the user attitude towards this enhanced MDD approach. 46 persons responded to the survey and the result indicated that in general, GCCT was useful and easy to use. The participants intended to use GCCT primarily because they thought that GCCT was useful. Users’ familiarity with computer games and MDD did not have a strong impact on users’ understanding and adoption of GCCT.

  • An evaluation of ontology based domain analysis for model driven development
  • 2015
  • Ingår i: International Journal on Semantic Web and Information Systems. - : IGI Global. - 1552-6283 .- 1552-6291. ; 11:4, s. 41-63
  • Tidskriftsartikel (refereegranskat)abstract
    • Although Domain Analysis DA is important for Model Driven Development MDD, traditional DA methods are demanding and not practical in many situations. When computer games are developed, game design problem domain is usually decided in a gradual way within iterations where software prototypes are constructed and playtest are performed. In such a case, it is not practical to fit a heavyweight DA in the highly iterative process. Researchers indicated that vocabularies were expected to automate game design. Such vocabularies can be reused in another form in DA tasks. In this research, the authors developed an ontology and a DA procedure based on it. To evaluate them, theoretical analysis, case studies, and a user acceptance survey were used. The results indicated that the ontology met the general requirement as a domain vocabulary, and it enhanced the DA process in an expected way. Most of external potential users 46 in total considered the ontology useful and easy to use.

  • A Semiotic Approach to Investigate Quality Issues of Open Big Data Ecosystems
  • 2015
  • Ingår i: Information and Knowledge Management in Complex Systems. - Cham : Springer Berlin/Heidelberg. - 9783319162744 ; , s. 41-50
  • Bokkapitel (refereegranskat)abstract
    • The quality of data models has been investigated since the mid-nineties. In another strand of research, data and information quality has been investigated even longer. Data can also be looked upon as a type of model (on the instance level), as illustrated e.g. in the product models in CAD-systems. We have earlier presented a specialization of the general SEQUAL-framework to be able to evaluate the combined quality of data models and data. In this paper we look in particular on the identified issues of ‘Big Data’. We find on the one hand that the characteristics of quality of big data can be looked upon in the light of the quality levels of the SEQUAL-framework as it is specialized for data quality, and that there are aspects in this framework that are not covered by the existing work on big data. On the other hand, the exercise has resulted in a useful deepening of the generic framework for data quality, and has in this way improved the practical applicability of the SEQUAL-framework when applied to discussing and assessing quality of big data.

  • Using a Living Lab Methodology for Developing Energy Savings Solutions
  • 2013

    • It is becoming increasingly important to create a sustainable environment. One important step is to reduce the energyconsumption. In Europe, 25% of the energy used is consumed by private households. How energy is produced and consumedin different European countries varies a lot, thus it is hard to develop general solutions based on country-specific traits. Theaim of this paper is to describe an approach to cross-country development of an energy savings solution. This paper reportson the usage of a method based on collecting users needs related to their current energy consumption, the actions they cantake, and the possible future solutions they want to see.

  • The Future of Information Systems in a Post-COVID World by TC8 (Information Systems)
  • 2021
  • Ingår i: Advancing Research in Information and Communication Technology. - Cham : Springer Berlin/Heidelberg. - 9783030817008 - 9783030817015 ; , s. 333-360
  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • This chapter consists of several sections which contain contributions from members of IFIP Technical Committee 8 (Information Systems). We highlight the accomplishments of Technical Committee 8 (TC8) and its working groups over its 50 years history, and then envisage possible strategies for the future of information systems (IS) in a post-COVID world. This chapter begins with an overall view of the diverse and changing roles of the IS field then moves forward to foresee environmental sustainability and digital glocalization in a post-COVID-19 world. Next, we review the achievements of TC8, the establishment of the working groups within it, and predict what TC8 has to offer into the future. Lastly, we identify the individual working groups of TC8 to detail their activities as important conduits of research and practice in the field of IS over the past 50 years, then imagine the roles of the TC8 working groups in a post-COVID landscape.

  • Enterprise Modelling for the Masses - From Elitist Discipline to Common Practice
  • 2016
  • Ingår i: The Practice of Enterprise Modeling. - Cham : Springer. - 9783319483924 - 9783319483931 ; , s. 225-240
  • Konferensbidrag (refereegranskat)abstract
    • Enterprise modelling (EM) as a discipline has been around for several decades with a huge body of knowledge on EM in academic literature. The benefits of modelling and its contributions to organizational tasks are largely undisputed. Thus, from an inside-out perspective, EM appears to be a mature and established discipline. However, for initiating serious innovations this view is not sufficient. This position paper takes an outside-in perspective on enterprise modelling and argues that EM is far away from reaching its maximum potential. EM is typically done by a limited number of people in organizations inclined to methods and modelling. What is captured in models is only a fragment of what ought to be captured. Many people actually develop some kind of model in their local practice without thinking about it consciously. Exploiting the potential of this “grass roots modelling” could lead to groundbreaking innovations in EM. The aim is to investigate integration of the established, often systematic and formalized practices of modelling in enterprises with local practices of creating, using and communicating model-like artifacts or objects of relevance for the overall organization.

    • The benefits of enterprise modeling (EM) and its contribution to organizational tasks are largely undisputed in business and information systems engineering. EM as a discipline has been around for several decades but is typically performed by a limited number of people in organizations with an affinity to modeling. What is captured in models is only a fragment of what ought to be captured. Thus, this research note argues that EM is far from its maximum potential. Many people develop some kind of model in their local practice without thinking about it consciously. Exploiting the potential of this “grass roots modeling” could lead to groundbreaking innovations. The aim is to investigate integration of the established practices of modeling with local practices of creating and using model-like artifacts of relevance for the overall organization. The paper develops a vision for extending the reach of EM, identifies research areas contributing to the vision and proposes elements of a future research agenda.

  • Users and Energy Savings - Their Perspectives and Needs
  • 2012
  • Konferensbidrag (refereegranskat)abstract
    • It is becoming increasingly important to create a sustainable environment for the future. This is a problem that is recognised but it still not evident what kind of solutions that would be beneficial and useful. However, one important step is to reduce the energy consumption. In Europe, 25% of the total amount of energy being consumed is consumed by private households. Hence, if private households decrease their energy consumption this would contribute to the environment in positive ways. The aim of this paper is to describe what kind of needs users have related to energy consumption and solutions for that. Our study have been carried out in a project called Smarties in which the objective is to develop solutions that stimulates users to decrease their energy consumption. This paper reports on the users needs related to their current energy consumption situation, the actions they want or can take, and the possible future solutions they want to se.
