    Novel Psychoactive Substances: Experienced effects, attitudes, and motivations among online drug community users2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of the present research is to contribute to the bridging of the knowledge gap pertaining to the field of Novel Psychoactive Substances (NPS) and its online community of users. The findings demonstrate that the community is characterized by robust group cohesiveness and counter public attitudes. The discussions functioned as a cumulative exchange of peer-to-peer generated knowledge and a social support system in service of harm reduction. The users were experienced drug users generally driven by recreation, novelty, and a range of instrumental purposes. They were also knowledgeable and presented a good degree of well-being. Some of the more conspicuous incentives for NPS use included the seeking of novel and exciting adventures, the enabling of safer drug use circumstances, and the guinea-pig-like self-experimenting in service of the community. Several distinct motivation and risk profiles were found at the level of drug groups. For example, the stimulants, opioids and GABA activating substances were associated with performance enhancement, coping, and high abuse liability, while the hallucinogens were related to self-exploration, spiritual attainment, and significantly lower abuse potential. Three user orientations are outlined: 1) the risk-negligent sensation seeker with an interest in stimulants and enhancement, 2) the self-medicating pursuer of coping with mistrust in public health and proneness for sedative drugs, and 3) the well-informed self-explorer advocating harm reduction and hallucinogens. It is concluded that the field of NPS needs to be approached with more sophistication than the broad brush approach of drugs in general. A one fits all preventive solution is likely to be ineffective at best and counterproductive at worst. We may also benefit from recognizing most drug use as an adaptive function with instrumental value rather than something pathologic, which will run the risk of fueling potentially harmful behaviors like self-medicating and avoidance of health care. Moreover, prohibition not only drives potentially harmful substance displacement but may also serve as the key incentive for engagement in risky behaviors. The current investigations could be a starting point for science based benefit-risk evaluations and the development of more appropriate prevention messages.

    Student teachers’ viewpoints of the current RE solution and how RE should be profiled in the future in Finland2017In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2017:4, 70-86 p.Article in journal (Refereed)
    Abstract [en]

    This study focuses on Finnish student teachers’ viewpoints of the current RE model and their views on how RE should be profiled in the future. The idea of this article is to formulate possible models to organize RE in Finland based on the data gathered by student teachers. The topic is very timely and urgent as Religious Education (hence RE) has been fiercely debated in different European countries. There have also been debates about the function and profile of, and the most suitable model for, RE in Finland. The data of this study consist of 149 essays written by 35 student teachers studying in a class-teacher program and 114 teacher students studying in a subject-teacher program. The data were analyzed by qualitative content analysis. The main research questions are: 1. What kinds of strengths and challenges do student teachers see in the current RE solution? 2. What kinds of RE-models would they prefer in the future? 3. According to them, what kinds of model scenarios could be formulated? Many student teachers prefer a model where RE is taught both according to an individual’s faith as well as collectively, irrespective of the individual students’ faiths. Could this kind of combination model take into account the strengths of both models (the current and joint models) and at the same time correct the problems associated with these models?

    Party choice and family influence in the age of late modernity: Students`reflections as first-time voters in a Norwegian parliamentary election2017In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2017:4, 48-69 p.Article in journal (Refereed)
    Abstract [en]

    This paper analyses how young first-time voters reflect their sources of influence on when considering a choice of party as they approached the 2013 parliamentary elections in Norway. Party identification has traditionally been regarded as resulting from social (class) identity, occupation or professional belonging and family influence. This view led to the much tested hypothesis of transfer of political orientations from one generation to another (Jennings & Niemi, 1974). Later, scholars like Giddens (1991) and Beck (1986) argued that social and political orientations are first and foremost characterized by reflexivity. Based on this we hypothesize that young people’s choice of party is characterized by a search for their political selves. Analysing interviews of 28 students, we found considerable support for both hypotheses where the majority voiced a strong family influence. Both groups also emphasise their independence and need for self-reflections on their choices. What characterises most of these young voter’s process of finding a political party is self-reflection on influence from either family upbringing and/or influence from peers, media or school. We therefore propose that the hypotheses should be regarded as complementary rather than rival.

    Med samhället i centrum – Medborgarskapsutbildningen och samhällskunskapsämnets relevans2017In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2017:4, 28-47 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to suggest "society" and "social analytical thinking" as the core concepts for the social science (Swedish: samhällskunskap) subject. Thus, the article contributes to the ongoing research debate on social science education by exploring the question whether social science is at risk of losing its position as the central citizenship subject in Swedish school. This risk is problematized and discussed. The authors argue that the relevance of the social science subject matter would be clarified and strengthened by making "society" and "social analytical thinking" into the core concepts of the subject. The proposal means that the scientific disciplines (i.e., political science, sociology, economics and law) that contribute to the social sciences subject by relating to these concepts can clarify the discipline-specific knowledge and perspectives that are considered crucial for a society to be formed and survive. The article also discusses community engagement and what may be a relevant level of ambition for compulsory citizenship education, from the perspective of the citizen as "a reflective spectator". The possibilities to develop the pupils' community, or social, engagement is illustrated by means of current Swedish classroom research on teachers' use of concepts and social analytical thinking in teaching.

    Samhällskunskap i den nya ämneslärarutbildningen: Samhällskunskapens innehåll och ämnesdidaktik vid 14 lärosäten i Sverige mellan 2009-20152017In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2017:4, 1-27 p.Article in journal (Refereed)
    Abstract [sv]

    Abstract: Syftet med artikeln är att analysera samhällskunskapsämnets innehåll i ämnes­lärarutbildningen vid lärosäten i Sverige. Avsikten är att analysera hur man vid olika lärosäten utformat ämnesinnehåll och ämnesdidaktisk integrering i kursplaner. Studien besvarar fyra frågor; I vilken omfattning det förekommer lärandemål i samhällskunskap om (1) faktuell kunskapsöverföring, vetenskaplig metodologi, granskande undersökningar; (2) normativt innehåll; (3) ämnesdiscipliner respektive flervetenskapliga tematiseringar samt (4) ämnesdidaktik. Kursplaner i samhällskunskap från 14 lärosäten har analyserats vid två tillfällen, 2009 och 2015, dvs. före och efter den senaste lärarutbildningsreformen i Sverige. Resultaten visar att det totala antalet lärandemål i samhällskunskapskurserna ökat med 21 % och att detta i hög grad betingas av att statsmakten lagt in fler lärandemål i examensförordningen jämfört med tidigare. Analysen visar (1) att inslagen av ämnesdidaktisk integrering ökat i kursplanerna, (2) att andelen flervetenskapliga tematiseringar minskat, (3) att mängden ämnesteoretiska lärandemål varit oförändrade men fått fler inslag av normativt färgade problemställningar samt (4) att inslagen av vetenskaplig metodologi varit oförändrade. Analysen av kursplanerna indikerar behov av ytterligare analys och ämnesdidaktisk forskning om samhällskunskapsämnet möjligheter gällande bl.a. tvärvetenskaplig integrering, vetenskaplig metodologi samt betydelsen av normativa ansatser.

    Taxonomy and Survey of Retransmission Based Partially Reliable Transport Protocols2002Report (Other academic)
    Abstract [en]

    The mismatch between the services offered by the two standard transport protocols inthe Internet, TCP and UDP, and the services required by distributed multimedia applicationshas led to the development of a large number of partially reliable transportprotocols. That is, protocols which in terms of reliability places themselves betweenTCP and UDP. This paper presents a taxonomy for retransmission based, partially reliabletransport protocols, i.e., the subclass of partially reliable transport protocols thatperforms error recovery through retransmissions. The taxonomy comprises two classificationschemes: one that classifies retransmission based, partially reliable transportprotocols with respect to the reliability service they offer and one that classifies themwith respect to their error control scheme. The objective of our taxonomy is fourfold:to introduce a unified terminology; to provide a framework in which retransmissionbased, partially reliable transport protocols can be examined, compared, and contrasted;to make explicit the error control schemes used by these protocols; and, finally, to gainnew insights into these protocols and thereby suggest avenues for future research. Basedon our taxonomy, a survey was made of existing retransmission based, partially reliabletransport protocols. The survey shows how protocols are categorized according to ourtaxonomy, and exemplifies the majority of reliability services and error control schemesdetailed in our taxonomy.

    A Study of Partially Reliable Transport Protocols for Soft Real-Time Applications2002Report (Other academic)
    Abstract [en]

    The profileration of multimedia applications, such as streaming video, teleconferencing,and interactive gaming has created a tremendous challenge for the traditional transportprotocols of the Internet – UDP and TCP. Specifically, many multimedia applicationsare examples of soft real-time applications. They have often relatively stringent requirementsin terms of delay and delay jitter, but typically tolerate a limited packet loss rate.In recognition of the transport service requirements of soft real-time applications,this thesis studies the feasibility of using retransmission based, partially reliable transportprotocols for these applications. The thesis studies ways of designing retransmissionbased, partially reliable transport protocols that are congestion aware and TCP compatible.Furthermore, the transport protocols should provide a service that, in terms ofperformance metrics such as throughput, delay, and delay jitter, are suitable for soft realtimeapplications. The thesis work comprises the design, analysis, and evaluation oftwo retransmission based, partially reliable transport protocols: PRTP and PRTP-ECN.Extensive simulations have been carried out on PRTP as well as PRTP-ECN. These simulationshave in part been complemented by some theoretical analysis. The results ofthe simulations and the analysis suggest that substantial reductions in delay jitter andimprovements in throughput can indeed be obtained with both PRTP and PRTP-ECN ascompared to TCP. While PRTP reacted too slowly to congestion to be TCP-friendly andaltogether fair, PRTP-ECN was found to be both TCP-friendly and reasonably fair.The thesis work also comprises an extensive survey on retransmission based, partiallyreliable transport protocols. Based on this survey, we have proposed a taxonomyfor these protocols. The taxonomy considers two dimensions of retransmission based,partially reliable transport protocols: the transport service, and the error control scheme.

    A Survey of TCP-Friendly Congestion Control Mechanisms for Multimedia Traffic2003Report (Other academic)
    Abstract [en]

    The stability and performance of the Internet to date have in a large part been due tothe congestion control mechanism employed by TCP. However, while the TCP congestioncontrol is appropriate for traditional applications such as bulk data transfer, it hasbeen found less than ideal for multimedia applications. In particular, audio and videostreaming applications have difficulties managing the rate halving performed by TCP inresponse to congestion. To this end, the majority of multimedia applications use eithera congestion control scheme which reacts less drastic to congestion and therefore oftenis more aggressive than TCP, or, worse yet, no congestion control whatsoever. Sincethe Internet community strongly fears that a rapid deployment of multimedia applicationswhich do not behave in a fair and TCP-friendly manner could endanger the currentstability and performance of the Internet, a broad spectrum of TCP-friendly congestioncontrol schemes have been proposed. In this report, a survey over contemporary proposalsof TCP-friendly congestion control mechanisms for multimedia traffic in the Internetis presented. A classification scheme is outlined which shows how the majority of theproposed congestion control schemes emanate from a relatively small number of designprinciples. Furthermore, we illustrate how these design principles have been applied ina selection of congestion control scheme proposals and actual transport protocols.

    Learning High-Energy Trauma Care Through Simulation2018In: Clinical Simulation in Nursing, ISSN 1876-1399, E-ISSN 1876-1402, Vol. 17, 1-6 p.Article in journal (Refereed)
    Abstract [en]

    Simulation provides the opportunity to learn how to care for patients in complexsituations, such as when patients are exposed to high-energy trauma such as motor vehicle accidents.The aim of the study was to describe nurses’ perceptions of high-energy trauma care through simulationin prehospital emergency care. The study had a qualitative design. Interviews were conductedwith 20 nurses after performing a simulated training series. Data were analyzed using a phenomenographicmethod. The result indicates that simulation establishes, corrects, and confirms knowledge andskills related to trauma care in prehosp ital emergency settings. Trauma knowledge is readily availablein memory and can be quickly retrieved in a future trauma situation.

    Smile for a while: The effect of employee-displayed smiling on customer affect and satisfaction2017In: Journal of Service Management, ISSN 1757-5818, E-ISSN 1757-5826, Vol. 28, no 2, 284-304 p.Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of this paper is to investigate the effect of employee-displayed smiling on customers' affective states (pleasure, arousal, and dominance) and satisfaction. Building on the stimulus-organism-response framework and theories of emotional contagion and feelings-as-information, the main hypothesis was that a smiling (vs non-smiling) employee significantly increases customer satisfaction through the mediating influence of pleasure. Design/methodology/approach - The study used a quasi-experimental two-group between-subjects design. A total of 210 customers at a large retail bank had a brief service encounter at the store entrance with a smiling (vs non-smiling) bank teller. Customers then went into the bank to do what they came to do. Before leaving the bank, customers completed a survey that included demographic information, affect (pleasure, arousal, and dominance), and measures of customer satisfaction. Findings - A smiling (vs non-smiling) employee had a significant positive impact on customer satisfaction. This effect was mediated by pleasure, but also, to a weaker extent, by dominance. These results contradict previous claims that smiling-induced emotional contagion does not remain throughout the completion of a service encounter. Practical implications - Managers should encourage, and potentially train, employees to act in ways associated with positive emotions. Managers could also hire employees based on how good they are at acting and expressing themselves in a genuinely positive manner and create a pleasant store atmosphere so that the feelings and behaviors displayed by frontline employees are genuine rather than inauthentic. Originality/value - This is the first experimental field study to examine the isolated effect that employee-displayed smiling has on customers' affective states and satisfaction. The results provide more direct evidence for the psychological processes justified by emotional contagion and feelings-as-information theories. Furthermore, the finding that dominance mediates the smiling-satisfaction link has never been shown before.

    Project title:  Women in the Arctic, 1818-2018

    The project Women in the Arctic examines the intercultural aspects of how women are represented in circumpolar societies.  It will place representations of women in migratory literature within the existing 'Northern' cultural landscapes and histories, but also seek a new methodology that analyses their position within the context of global diversity.  Migration often leads to the emergence of ‘geographically diffuse socio-cultural fields’ (Olwig, 2003), which cross political and geographical borders.  Although these always impose some sort of structural constraint, this does not necessarily change the nature or continuity of the relationship, feelings of affinity or images of difference and/or transgression.  The project focuses on: 

    1. understanding the diverse roles that women have played in the history of the Arctic, both as colonisers and colonised, and
    2. demonstrating the contemporary issues affecting women in the Arctic.

    Flooding tolerance of four floodplain meadow species depends on age2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 5, e0176869Article in journal (Refereed)
    Abstract [en]

    Numerous restoration campaigns focused on re-establishing species-rich floodplain meadows of Central Europe, whose species composition is essentially controlled by regular flooding. Climate change predictions expect strong alterations on the discharge regime of Europe's large rivers with little-known consequences on floodplain meadow plants. In this study, we aim to determine the effects of flooding on seedlings of different ages of four typical flood meadow species. To this end, we flooded seedlings of two familial pairs of flood meadow species of wetter and dryer microhabitats for 2 weeks each, starting 2, 4, 6, and 8 weeks after seedling germination, respectively. We show that a 2-week-flooding treatment had a negative effect on performance of seedlings younger than 6 weeks. Summer floods with high floodwater temperatures may have especially detrimental effects on seedlings, which is corroborated by previous findings. As expected, the plants from wet floodplain meadow microhabitats coped better with the flooding treatment than those from dryer microhabitats. In conclusion, our results suggest that restoration measures may perform more successfully if seedlings of restored species are older than the critical age of about 6 weeks before a spring flooding begins. Seasonal flow patterns may influence vegetation dynamics of floodplain meadows and should, therefore, be taken into account when timing future restoration campaigns.

    Inflationary alpha-attractor cosmology: A global dynamical systems perspective2017In: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 95, no 8, 083517Article in journal (Refereed)
    Abstract [en]

    We study flat Friedmann-Lemaitre-Robertson-Walker alpha-attractor E- and T-models by introducing a dynamical systems framework that yields regularized unconstrained field equations on two-dimensional compact state spaces. This results in both illustrative figures and a complete description of the entire solution spaces of these models, including asymptotics. In particular, it is shown that observational viability, which requires a sufficient number of e-folds, is associated with a particular solution given by a one-dimensional center manifold of a past asymptotic de Sitter state, where the center manifold structure also explains why nearby solutions are attracted to this "inflationary attractor solution." A center manifold expansion yields a description of the inflationary regime with arbitrary analytic accuracy, where the slow-roll approximation asymptotically describes the tangency condition of the center manifold at the asymptotic de Sitter state.

    Abstract [en]

    This article reports from a study of reliability in the Swedish national reading test in ninth grade. Based on a representative sample of 500 students, the study investigates internal consistency and power to discriminate between different levels of reading ability. Data was analyzed using both classical test theory and Rasch modelling. Results from the study suggest that neither the subscales nor the whole scale of items included in the test reach desirable levels of internal consistency. Three out of four subscales include items with strikingly low degree of internal correlation (.23–.46). Furthermore, results from the Rasch analysis suggest that the test is capable of reliable separation between two groups of test-takers only: lower performing students and higher performing students. The empirical support for categorizing student performances into six separate grade levels is therefore questionable. Implications for future development of the national test of reading are discussed.
