    Enabling privacy of real-life LBS: A platform for flexible mobile service provisioning2007In: New Approaches for Security, Privacy and Trust in Complex Environments, Springer, 2007, p. 325-336Conference paper (Refereed)
    Abstract [en]

    Privacy in computerized environments is perceived very differently depending on the respective point of view. Often "privacy enhancing technologies" - initiated by the user, as a measure of self-defense - are seen as conflicting with business goals such as cost-efficiency, revenue assurance, and options for further business development based on existing data. This paper presents the design and implementation of an architecture and prototype for privacy-friendly, interoperable location-based services (LBS), based on intermediation of location data via a location middleware component. The aim is to combine privacy-friendliness, efficiency, and market potential. Therefore the security interests of the stakeholders are analyzed and an architecture solution including an intermediary is introduced. Then the prototype implementation (at a mobile operator) is described and the usage of the prototype for a commercial service and product offer by the operator involved in the development is discussed.

    How the Final Swedish Clinical Exam prepares thenursing students for their future challenges- qualitative analysis2014In: Creative Education, ISSN 2151-4755, E-ISSN 2151-4771, no 5, p. 1887-1894Article in journal (Refereed)
    Abstract [en]

    The national clinical final examination (NCFE) plays an important role in order to measure thelevel of knowledge and performance of nursing students. Our findings indicate that the design of the NCFE is beneficial for the students' clinical reasoning and problem solution in the caring situation. The aim of this study was to investigate the experiences of the NCFE from lecturers who corrected the written part examination. A further aim was to study the lectures and the RN during observation in the bedside part of the examination. The NCFE is divided into two parts: a theoretical (written) part and a practical (bedside) part. In nursing education it is essential to assess nursing competencies for the future professional role such as the assessment of clinical competence that has become central to evaluate what outcomes are assessed. In addition, it provides a valuable approach to measure the level of knowledge and performance of nursing students. Future development of the NCFE is necessary  egarding the degree to which the examination meets learning objectives and educational results.

    The Inclusion of Minority Religious Education in the Finnish Comprehensive School: A Teacher and Teacher Coordinator Perspective2013In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2, p. 93-114Article in journal (Refereed)
    Abstract [en]

    The Finnish education system offers faith-specific religious education throughout the comprehensive school. Today separate minority religious classes are offered parallel to the majority Lutheran and secular ethics education. The purpose of this study is to investigate how minority RE teachers and teacher coordinators view the inclusion of minority religious education in the school culture. Teacher and coordinator perspectives are investigated through an interview study with 23 religion teachers and 3 teacher coordinators in the Helsinki metropolitan area. The results show that teachers and coordinators experienced education as gaining stronger acceptance and equality in the school culture. However, issues of exclusion and discrimination emerged which raise questions on the viability of the current system of RE. The study argues for a need to improve structural issues in education as well as increased teacher participation and dialogue in the school culture.

    Expected Bit Rate for Terminals Moving According to the Random Waypoint Model in a WLAN Cell2013Conference paper (Refereed)
    Abstract [en]

    The IEEE 802.11 standard defines the different bit rates and modulation schemes to which a WLAN device may adapt according to the channel quality. User mobility may also have an impact on the available bit rate. This paper presents a study of the bit rate evolution along time for devices that move according to the Random Waypoint mobility pattern in WLAN cells. Simulation has been applied in order to obtain statistical results that permit to characterize the evolution of the bit rate behavior along time and to compute average results in the ideal case (without interference) and in the presence of interfering devices. Our results can be useful in the solution of optimization problems in which decision on where to connect must be taken based on some minimum guaranteed bit rate. They also can be useful in the design of inter and intra-cell handover methods and load balancing schemes.

    Multi-objective Optimization of WLAN Associations with Improved Handover Costs2014In: IEEE Communications Letters, ISSN 1089-7798, E-ISSN 1558-2558, Vol. 18, no 11Article in journal (Refereed)
    Abstract [en]

    The deployment of a large number of access points in public areas presents a new paradigm in which a given station may be served by more than one access point at a time. Recently, a network model has been proposed to derive the optimal association strategy for the stations by solving a linear optimization problem. According to that model, a station cannot download data while performing a handover. In this letter, we demonstrate that, even in static conditions (i.e., no mobility and constant load in the cell), an association strategy can force a handover. We thus propose a multi-objective optimization function that maximizes the download rates and minimizes the number of handovers. As a handover implies an extra cost due to necessary signaling to be exchanged, we propose a new handover cost function that takes into account the extra bandwidth. Using the new strategy, the system throughput slightly decreases, and the number of handovers is reduced.

    Energy Efficient Virtual Machine Consolidation under Uncertain Input Parameters for Green Data Centers2015In: 2015 IEEE 7th International Conference on Cloud Computing Technology and Science (CloudCom), IEEE, 2015, p. 436-439Conference paper (Refereed)
    Abstract [en]

    Reducing the energy consumption of data centers and the Cloud is very important in order to lower CO2 footprint and operational cost (OPEX) of a Cloud operator. To this extent, it becomes crucial to minimise the energy consumption by consolidating the number of powered-on physical servers that host the given virtual machines (VMs). In this work, we propose a novel approach to the energy efficient VM consolidation problem by applying Robust Optimisation Theory. We develop a mathematical model as a robust Mixed Integer Linear Program under the assumption that the input to the problem (e.g. resource demands of the VMs) is not known precisely, but varies within given bounds. A numerical evaluation shows that our model allows the Cloud Operator to tradeoff between the power consumption and the protection from more severe and unlikely deviations of the uncertain input.

    Minimizing the impact of the handover for mobile users in WLAN: A study on performance optimization2016In: Computer Networks, ISSN 1389-1286, E-ISSN 1872-7069, Vol. 107, p. 292-303Article in journal (Refereed)
    Abstract [en]

    IEEE 802.11 based Wireless LANs are an important piece in today’s communication infrastructure in order to provide high speed wireless Internet access to static or quasi mobile users. For large WLAN deployments (i.e., Campus or enterprise WLAN), it is important to understand the impact of user mobility and handovers on the system performance. In this article, we have developed a performance model for a set of networked 802.11 based WLAN Access Points, which is based on a Mixed Integer Linear Program (MILP). The objective function tries simultaneously to maximize the total system rate while at the same time minimizing the number of handovers for a configurable handover signaling rate. Because of the conflicting nature of the two objective functions, such multi-objective optimization is difficult to explore. A detailed evaluation of the model using several scenarios involving both different numbers of static and mobile users shows that our formulation allows trading off those two objectives in a robust way.

    Optimising for Energy or Robustness? Trade-off for VM Consolidation under Uncertainty2016In: Optimization Letters, ISSN 1862-4472, E-ISSN 1862-4480Article in journal (Refereed)
    Abstract [en]

    Reducing the energy consumption of virtualized datacenters and the Cloud is very important in order to lower CO2 footprint and operational cost of a Cloud operator. However, there is a trade-off between energy consumption and perceived application performance. In order to save energy, Cloud operators want to consolidate as many Virtual Machines (VM) on the fewest possible physical servers, possibly involving overbooking of resources. However, that may involve SLA violations when many VMs run on peak load. Such consolidation is typically done using VM migration techniques, which stress the network. As a consequence, it is important to find the right balance between the energy consumption and the number of migrations to perform. Unfortunately, the resources that a VM requires are not precisely known in advance, which makes it very difficult to optimise the VM migration schedule. In this paper, we therefore propose a novel approach based on the theory of robust optimisation. We model the VM consolidation problem as a robust Mixed Integer Linear Program and allow to specify bounds for e.g. resource requirements of the VMs. We show that, by using our model, Cloud operators can effectively trade-off uncertainty of resource requirements with total energy consumption. Also, our model allows us to quantify the price of the robustness in terms of energy saving against resource requirement violations.

    Joint User Association and Energy Aware Routing for Green Small Cell mmWave Backhaul Networks2017In: 2017 IEEE Wireless Communications and Networking Conference (WCNC), IEEE, 2017Conference paper (Refereed)
    Abstract [en]

    A dense deployment of small cells is one of the key characteristics envisioned for future 5G mobile networks in order to provide the required capacity increase. To cut cabling costs, small cells are foreseen to form multihop topologies using high capacity backhaul wireless links in the mmWave bands. Such small cells are deployed within the coverage area of a macro cell (eNB) to provide localized capacity where needed according to the well known Heterogeneous Network concept (HetNet). However, green networking will be very important because powering on unnecessarily a massive amount of small cells may lead to increased OPEX and CO2 emission. In this paper, we propose an optimization model that minimizes the total power consumption of 5G HetNets deployments while providing the required capacity and coverage. Our model jointly optimizes the user association, routing in the multihop backhaul and decides to power on or off the small cells to serve the user demands. Our numerical evaluation show significant power savings over a large range of traffic demand distributions while keeping the blocking probability low.

    Abstract [en]

    Results of this interview survey with eight officers from the Swedish Public Employment Service show that the core business of the Employment Service is extensively evaluated within a major ongoing reorganization. Evaluation results are used at higher levels in the organization for development of information technology, organizational changes and method training of the officers in the core business. That promotes the prerequisites for professional practice. Evaluations can further support the development of the service to job seekers if used more directly in the practice and if the officers in the core business are given greater influence over the evaluation criteria.

    Towards a systemic holistic security management2002Other (Other (popular science, discussion, etc.))
    Abstract [en]

    Information System Security and its management "is a parasite on the profit" Gerald Kovacich.



    This thesis presents research intended to both modify the understanding for, and to introduce information system security not only as a cost factor but also as a business enabler for eCommerce systems. To achieve this, system theoretic concepts will be applied to information security management, taking technology, sociology and business aspects into consideration. The first aspects dealt with are security conception and system specification. A set of requirements for electronic money systems has been developed. However, security management does not only consist of requirement specifications, but must also open for an economically and socially acceptable implementation. Therefore we have developed a holistic framework for security management. This framework describes the activities and workflows that lead to satisfactory security levels in eCommerce. To be able to develop an understandable framework we apply black boxing in order to hide details. The development progress results in investigations of some of the black boxes mentioned. To motivate the need of inclusion in the framework, two of these inquires will be presented, where the first one deals with the improvement of a risk assessment methodology for faster application in e-commerce, and the second one with the influence of the Internet on privacy.

    Technology has influenced human lives since the beginning of mankind. Sociologists have described the effects that technology has on society as structuring or symbolic. We will use the same concepts to investigate the capability of the Internet to influence privacy. We analyse the structuring and symbolic effects of technology on privacy and thereby demonstrate some potentials of Internet technology and their effect on our life in society

    Initial photo-degradation of PCDTBT:PC 70 BM solar cells studied under various illumination conditions: Role of the hole transport layer2019In: Solar Energy, ISSN 0038-092X, E-ISSN 1471-1257, Vol. 183, no 1, p. 234-239Article in journal (Refereed)
    Abstract [en]

    ncapsulated organic solar cells often show a burn-in behaviour under illumination. This burn-in manifests itself as a rapid performance loss followed by a much slower progression of the degradation. Here we investigate the burn-in for PCDTBT:PC 70 BM solar cells under a wide range of illumination intensities. We find that increasing the sunlight concentration from 1 Sun to up to 100 Suns does not change the degradation behaviour, i.e. the dependence of all principal photovoltaic parameters on the dose of solar exposure (in Sun hours). This suggests that the degradation mechanisms under solar concentration (≤100 Suns) are the same as those observed under 1 Sun. This result makes it possible to use concentrated sunlight for accelerated stability assessment of these devices. We also find that devices with PEDOT:PSS as hole transport material show a rapid drop in open-circuit voltage of around 100 mV during the first Sun hour of light exposure. By replacing PEDOT:PSS with MoO 3 this initial process can be prevented and only the much slower part of the photo-degradation takes place.

    Prolonged latent phase of labour: Prevalence, labour outcomes, quality of care, women’s experiences and preferences, and psychometric properties of a questionnaire2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall aim of this thesis was to investigate the prevalence and labour outcome of a prolonged latent phase of labour, quality of care, women’s experiences and preferences during labour, and to psychometrically test a questionnaire.

    Methods: Qualitative and quantitative methods. Sixteen primiparous women’s preferences for care during a prolonged latent phase of labour were studied with focus-group and individual interviews and analysed with content analysis (I). From a one-year cohort of 2660 women, 1554 women with a spontaneous onset of labour were invited to participate and 1389 women accepted invitation (II-IV). Data from 1343 women’s birth records were analysed with descriptive and analytic statistics (II). 758 women, (RR 64%), 343 primiparous and 415 multiparous, responded to the Intrapartal-specific Quality from Patients Perspective Questionnaire, QPP-I (III), the Early Labour Experience Questionnaire, ELEQ (IV) and additionally birth-related items. Data were analysed with descriptive, analytic, and psychometric statistics.

    Main findings: According to women’s self-reports, 23% of women with a spontaneous onset of labour had a prolonged latent phase (>18 hours), which was associated with more obstetrical interventions and instrumental births (II). These women preferred individualised care (I), rated the quality of their intrapartum care lower, were less content with the birth experience, and had more negative feelings during labour and birth than women with a shorter latent phase (III). The ELEQ was translated and adapted to Swedish and resulted in two questionnaires, one for primiparous women, SWE-ELEQ-PP, and one for multiparous women, SWE-ELEQ-MP. Both are valid and reliable and can be used to evaluate early labour care in Sweden (IV).

    Conclusions: A prolonged latent phase of labour can be regarded as a risk factor. It can result in more obstetrical interventions, more instrumental births, a lower perceived quality of care, and a more negative birth experience regardless of parity. Differences in parity must be considered when evaluating early labour care during the latent phase of labour, with special focus to primiparous women.

    Early labour experience questionnaire: Psychometric testing and women's experiences in a Swedish setting2018In: Midwifery, ISSN 0266-6138, E-ISSN 1532-3099, Vol. 64, p. 77-84Article in journal (Refereed)
    Abstract [en]

    Objective: (a) to psychometrically test the Early Labour Experience Questionnaire (ELEQ) among both primi- and multiparous women giving birth in a Swedish setting, and (b) to describe and compare their experiences during early labour in relation to background characteristics. Design: a cross-sectional study. Setting: a county in Sweden. Participants: primi- and multiparous women with a spontaneous onset of labour after gestational week 37 + 0. In total, n = 1193 women were invited, and n = 754 responded the questionnaire, with a final total of n = 344 primi and n = 410 multiparous women. Methods: the ELEQ was translated with cross-cultural adaptation. The validity was determined using exploratory factor analysis with principal axis factoring analyses. Reliability was estimated from the internal consistency using Cronbach's alpha. The relationship between the questionnaire and the demographic characteristics of the participating women were analysed using ANOVA and t-test. Findings: an explorative factor analysis showed a three-factor solution for primiparas women (SWE-ELEQ-PP) consist of 23 items and a stable factor structure that explained 49.2% of the total variance with sufficient reliability coefficients (0.81–0.86). A four-factor solution for multiparous women (SWE-ELEQ-MP) consist of 22 items, with 52.62% of the total variance explained and with adequate internal consistency reliability coefficients (0.77–0.86) for three factors and relatively low stability (0.62) for the fourth factor with two items. Primiparous women scored significantly higher on items about feeling confused, and significantly lower on some items measuring emotional wellbeing and perceptions of midwifery care compared to multiparous women. Primiparous women with longer early labour (>18 h), scored significantly lower on the perceptions of midwifery care. Primi- and multiparous women who were dissatisfied with their telephone conversation or with not being admitted during early labour, scored significantly lower on emotional wellbeing, higher regarding emotional distress, and significantly lower about perceptions of midwifery care. Key conclusions: the SWE-ELEQ-PP and SWE-ELEQ-MP are considered valid questionnaires for use in a Swedish setting. Differences exist between parity and the factor structure and experiences in early labour vary. Women less content with early labour management decisions rated perceived midwifery care lower regardless of parity. Implication for practice: the questionnaire can be used to evaluate early labour care in a Swedish setting. The result suggests that differences according to parity exist and should be addressed when managing early labour care and a more individualised approach requires considerations.

    Women's labour experiences and quality of care in relation to a prolonged latent phase of labour2019In: Midwifery, ISSN 0266-6138, E-ISSN 1532-3099, p. 155-164Article in journal (Other academic)
    Abstract [en]

    im: To describe primiparous and multiparous women's labour experiences and their perception of quality of intrapartum care, in relation to background characteristics and length of latent phase of labour prior to admittance to labour ward. Design: A cross-sectional study. Setting: A middle-sized hospital in a rural county in western part of Sweden. Participants: Primiparous and multiparous women, both low-risk and risk, with a spontaneous onset of labour after gestational week 37+0 were included. In total, n =1193 women were invited, and n = 757 responded the questionnaire, n = 342 primiparous and n = 415 multiparous women. Methods: The Intrapartal-specific Quality from Patient Perspective (QPP-I), with responses on perceived reality and subjective importance, was used for data collection. QPP-I covers ten factors of quality of care. Background characteristics, length of latent phase of labour, global items about labour experience and items regarding feelings during labour and birth were included. Data were analysed with descriptive and analytic statistics. Findings: All factors in QPP-I were rated higher for subjective importance than perceived reality, except for information about selfcare, for both primi- and multiparous women. Labour experience, perceived reality of quality of care, and feelings were related to length of the latent phase of labour. Primiparous women with a prolonged latent phase (>18 h) had significantly lower scores regarding six out of ten QPP-I factors (PR); Information procedures, Information self-care, Commitment (midwives), Commitment (enrolled nurses), Midwives present, and Partner/ significant others. They scored lower on Experience birth as normal and Safe during labour and birth. The felt less proud and felt more ignored by professionals. Multiparous women with a prolonged latent phase of labour scored significantly lower on one QPP-I factor, Commitment (midwives). They also scored lower on Control over the situation and felt less safe during labour and birth. Key Conclusion: Women's perception of quality of intrapartum care, the birth experience and feelings are related to length of the latent phase of labour. Women perceive quality of intrapartum care as being lower than its subjective importance. Implications for Practice: A prolonged latent phase of labour can be regarded as a risk factor for a more negative birthing experience.

    Prevalence of Prolonged Latent Phase and Labor Outcome: Review of Birth Records in a Swedish Population2018In: Journal of midwifery & women's health, ISSN 1526-9523, E-ISSN 1542-2011, Vol. 63, no 1, p. 33-44, article id JMWH12704Article in journal (Refereed)
    Abstract [en]

    The prevalence of a prolonged latent phase of labor has been described as ranging from 5% to 6.5% in previous research. The aim of this study was to describe the prevalence of the prolonged latent phase of 18 hours or more, based on women's report, in women intending vaginal birth and who had spontaneous onset of labor. An additional aim was to compare the incidence of obstetric interventions, and the labor and neonatal outcomes in women with and without a prolonged latent phase.

    METHODS:

    A descriptive and comparative study was performed in a mid-sized hospital in western Sweden. The sample consisted of 1343 birth records of women who intended vaginal births and who had spontaneous onset of labor at 37 or more weeks' gestation during a one-year period (2013-2014). Background characteristics, obstetric interventions, and labor and neonatal outcomes were compared between women with latent phases lasting less than 18 hours and 18 hours or more, based on women's self-report. Odds ratios with 95% confidence intervals were calculated for the different exposure variables.

    A prolonged latent phase lasting 18 hours or more occurred in 23% of all births analyzed (n = 1343). A prolonged latent phase was more common among nulliparous women (29.2%) but also common for multiparous women (17%). Nulliparous and multiparous women who experienced a prolonged latent phase were more often exposed to amniotomy during latent phase. For nulliparous women, the adjusted odds ratio (aOR) was 11.57 (95% confidence interval [CI], 5.25-25.51) and for multiparous women the aOR was 18.73 (95% CI, 9.06-38.69). Similarly, amniotomy during active phase was more common for both nulliparous and multiparous women who experienced a prolonged latent phase (aOR, 4.05; 95% CI, 2.53-6.47 and aOR, 3.93; 95% CI, 2.43-6.37, respectively). Women with latent phases of 18 hours or more, more often experienced augmentation of labor during all phases, especially during latent phase. For nulliparous women, the aOR was 10.13 (95% CI, 2.82-36.39) and for multiparous women, aOR was11.9 (95% CI, 3.69-38.71). A prolonged latent phase was associated with more instrumental vaginal births for multiparas (aOR, 2.58; 95% CI, 1.27-5.26) and emergency cesarean regardless of parity (nulliparous women: aOR, 3.21; 95% CI, 1.08-9.50 and multiparous women: aOR, 3.93; 95% CI, 1.67-9.26).

    Based on women's self-report, the prevalence of a prolonged latent phase in women at term who planned a vaginal birth and had spontaneous onset of labor was higher than previously reported. Women with a prolonged latent phase were more likely to receive obstetric interventions. Assisted vaginal birth was more common for nulliparous women with prolonged latent phase and emergency cesarean occurred more frequently for both nulliparous women and multiparous women with a prolonged latent phase.

    Primiparous women's preferences for care during a prolonged latent phase of labour2015In: Sexual & Reproductive HealthCare, ISSN 1877-5756, E-ISSN 1877-5764, Vol. 6, no 3, p. 145-150Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate primiparous women's preferences for care during a prolonged latent phase of labour. Methods: A qualitative study based on focus groups and individual interviews and analysed with inductive content analysis.Results: Sixteen primiparous women with a prolonged latent phase of labour >18 hours were interviewed in five focus groups (n = 11) or individually (n = 5). One main category emerged “Beyond normality – a need of individual adapted guidance in order to understand and manage an extended latent phase of labour” which covers the women's preferences during the prolonged latent phase. Five categories were generated from the data: “A welcoming manner and not being rejected”, “Individually adapted care”, “Important information which prepares for reality and coping”, “Participation and need for feedback” and “Staying nearby the labour ward or being admitted for midwifery support”. Women with a prolonged latent phase of labour sought to use their own resources, but their needs for professional support increased as time passed. A welcoming attitude from an available midwife during the latent phase created a feeling of security, and personally adapted care was perceived positively. Conclusions:  Women with a prolonged latent phase of labour preferred woman-centred care. Midwives play an important role in supporting these women. Women's need for midwifery-support increases as the time spent in latent phase increases.

    Tjänstemötet: Interaktionens kommersiella, byråkratiska och social logik2007Doctoral thesis, monograph (Other scientific)
    Abstract [en]

    The subject of this thesis is interaction in the service encounter. The aim is to describe and explain the service encounter interaction with a special focus on the social and organisational context. The contextual focus is related to two overriding questions: What significance does the human interaction have for the service encounter? What significance does the organisational context have for the service encounter?

    The result show that even though the communication consists of four discerned phases – salutation, the subject of the call, concluding the subject, and rounding off the call, each phase also displays contradictions. Consequently, there are both relational and instrumental utterances, as well as symmetrical and asymmetrical aspects of the conversations.

    These contradictory results of the relational-instrumental and symmetrical-asymmetrical features are explained when interaction is viewed in terms of three different sets of logic – the commercial, the bureaucratic, and the social. Every logic is constituted by a number of characteristics, each contributing to the shape of the interaction and to the relationship between the customer and the employee.

    Analytically speaking, the three forms of logic can be described in terms of their respective field of action and rationality, that is, what the actors talk about and what the purpose of the talk is. It is shown that the actors must prioritise between economic, administrative and personal areas within a limited time of action. It is also clear that the disparate rationalities, that is, economic, executive and recognition, all exercise influence over the service encounter, which means that acts aiming at a specific goal are restricted by the objectives of the other logics. Therefore there is a certain self-regulating function in the antagonism between the logics. The positions of the employee in relation to the customer, the organisation and the so-called collective customer mean that there are demands made from three qualitatively different directions. There is, in other words, a three-bosses dilemma for employees. The different positions of the employee also entail three different asymmetrical relationships in which either the customer or the employee has the advantage. This position constructs the hierarchy of dominance between employee and customer.

    To conclude, the interaction constitutes a complex relationship between the characteristics of the logics and when these combine the interaction of the service encounter is shaped. The fact that the service encounter involves human interaction means that there is a counter balance against the organisational ascendancy.
