    Fotbollens gemensamma språk: En studie om språkets betydelse för fotbollsspelare och språkutbildningens framtida plats på fotbollsplanen2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Fotbollens gemensamma språk kan framstå som en kliché och som något påhittat. Syftet med denna studie är att ge en bild av hur svensk fotbollsverksamhet arbetar med inkludering och olika faktorer som berör svensk integration med fokus på språkinlärning. Studien är kvalitativ och undersöker hur två professionella fotbollsspelare ser på sin integrationsprocess och hur de ser på sin egen språkinlärning rörande det svenska språket samt språkets betydelse för integration, delaktighet och gemenskap.

    En representant från Stockholmsidrotten applicerar dessutom ytterligare perspektiv på hur fotbolls- föreningar i Stockholmsområdet arbetar med integrationsfrågor. Studien tar sitt avstamp utifrån begreppen integration, inkludering, delaktighet och gemenskap samt språk, som även är centrala begrepp inom idrottsverksamhet och delger utifrån ett bredare pedagogiskt perspektiv hur den idrottsliga föreningsverksamheten inom Stockholmsområdet arbetar med integration av nyanlända till Sverige.

    Studiens metodologiska utgångspunkt bygger på en hermeneutisk tradition inom vilken studiens deltagare intervjuats semistrukturerat och ostrukturerat. Deltagarnas berättelser har sedan tolkats, översatts och analyserats utifrån delvis samtalsanalys och delvis narrativ analys.

    Resultatet av studien visar att fotbollsföreningar idag utför ett tungt arbete gällande integration av individer med utländsk bakgrund. Det finns i dagsläget ytterst få initiativ som bygger på språkinlärning som inkluderande metod. Däremot finns ett stort utrymme för fotbollsverksamhet, skola och samhälle att samarbeta och tillsammans inrätta denna sorts verksamhet.

    Swedish Information Economy : A Preliminary Account2017Inngår i: Dilemmas 2015 Papers from the 18th Annual International Conference Dilemmas for Human Services: Organizing, Designing and Managing / [ed] Sisse Finken, Christina Mörtberg, Anita Mirijamdotter, Vaxjo, 2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The recent developments and adoptions of digital technologies give rise to the growth of information economies, understood as an aggregate of economic activities that produce informational outputs. Several key characteristics of an information economy differ to the conventional economic wisdom derived from the industrial age, which may impose governmental policy implications and therefore constitutes a key question: how to govern the newly emerged information economy with the thinking of the industrial age economy. Resolving this problem requires, among others, comprehensive understanding of information economies. To that end, Sweden is among the most advanced adopters of digital technologies and represents therefore a suitable empirical base for the investigation of an information economy. This paper offers preliminary results from a first ever account of the Swedish information economy in terms of its value created, jobs and wages; this account shows that the Swedish economy is dominated by its information economy, which requires a careful attention of policy makers.

    The Swedish Information Economy: Current Evidence and Key Government Policy Implications2017Inngår i: Proceedings of the 8th International Conference on Society and Information Technologies (ICSIT 2017), Orlando, USA, 2017, 23-28 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    It is well known that most of the largest economies in the world are becoming information economies (understood as an aggregate of economic activities that produce information outputs) in terms of value added (GNP) and jobs. Sweden is among the most advanced adopters of ICT and represents therefore a suitable empirical base for the investigation of an information economy. The data reveal that the largest part of the Swedish economy in terms of GNP value added is constituted by information services. This study presents some surprising economic structures never before uncovered, which are discussed here and then contextualized in terms of implications for public policy making.

    Software Programmer Productivity: A Complementary-Based Research Model2017Inngår i: Proceedings of the 25th European Conference on Information Systems, Guimarães, Portugal, 2017, 2755-2766 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The identification of the factors that condition a software programmer’s productivity remains a key challenge for both scholars and practitioners. While a number of studies have focused on the impact of one or a few particular factors, the way these factors jointly condition programmer productivity is still unknown. This paper presents a conceptual model aimed at a comprehensive understanding of the factors that complement each other to govern the productivity of a software programmer. The model is based on complementarity theory and its systems approach and addresses an individual worker’s productivity, which accounts for cognitive, technological, and organizational characteristics. The analyzed factors are organized into a system of complementarities, offering two propositions that specify the conditions of a programmer’s productivity. The model’s key contribution lies in its unique configuration of two systems of complementarities, which have the potential to add to the literature on the productivity of software programmers. The proposed model can be employed as a guidance for the design of empirical investigations of the conditions of individual software programmers’ productivity as well as information worker productivity in general.

    Är emotionellt krävande yrken också kvävande yrken?: En deskriptiv studie av skillnaderna i män och kvinnors uttag av sjukpenning.2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Det finns ett gap mellan kvinnor och män avseende sjukskrivningar, då kvinnor är sjukskrivna i större utsträckning än män. Detta har av forskningen förklarats av ett antal olika faktorer. Vi ville därför undersöka om könsskillnaderna i sjukskrivningar fortfarande gäller, samt om de faktorer som tidigare forskning har lyft fram som förklaringar till skillnader fortfarande är hållbara för att förstå fenomenet.

    Vi har kommit fram till att skillnaderna i uttag av sjukpenning idag finns kvar mellan män och kvinnor. Den procentuella skillnaden mellan könen har under en förhållandevis lång tid varit konstant, trots att de totala sjuktalen har sjunkit. Vi har därför valt att studera tre tidigare förklaringsfaktorer till dessa skillnader för att se om dessa har förändrats sedan millennieskiftet. De tre förklaringsfaktorer utgår från fördelningen mellan könen av obetalt hushållsarbete, den könssegregerade arbetsmarknaden och slutligen på ekonomiska drivkrafter. Genom sekundäranalys av data från bland annat Statistiska centralbyrån (SCB) har vi tittat på hur de ovan angivna faktorerna har förändrats under olika år. Eftersom andelen sjukskrivningar mellan könen har varit konstant borde således även förklaringsfaktorerna ha varit konstanta.

    Utifrån resultatet kan vi sluta oss till att utförandet av det obetalda arbetet är mer jämställt mellan könen. Dock ser arbetsmarknaden ut att vara lika segregerad som tidigare forskning har visat, och de ekonomiska drivkrafterna har inte heller förändrats mellan könen. Vår slutsats är att det inte är könssegregeringen i sig, utan skillnader i de krav och den kontroll som föreligger mellan kvinno- och mansdominerade yrken, som kan tänkas vara en av flera faktorer som leder till att kvinnor har ett större uttag av sjukpenning än män.

    Stability and change in international policy-making: A punctuated equilibrium approach2017Inngår i: The Review of International Organizations, ISSN 1559-7431, E-ISSN 1559-744XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    International organizations (IOs) have developed into important policy venues beyond the state. Yet our understanding of the broader dynamics of IO policy-making is limited. This article offers the first comparative analysis of macro patterns in IO policy-making. Theoretically, we draw on punctuated equilibrium theory to develop hypotheses about stability and change in the orientation of IO policy agendas. Empirically, we examine novel data on the policy output of five general-purpose IOs between 1980 and 2015, combining statistical analysis and comparative case illustrations. The analysis yields two central results. First, the policy agendas of all five IOs display patterns of punctuated equilibria, with longer periods of stability interrupted by shorter periods of dramatic change. Second, the level of institutional friction in decision-making contributes to variation in punctuations across IOs and within IOs over time. The results suggest four broader implications: (1) punctuated equilibrium theory applies to a broader empirical domain than previously thought; (2) patterns of change in IOs are more complex than conventionally expected; (3) institutional friction matters for IOs’ responsiveness to societal demands and problem pressures; and (4) deeper integration of punctuated equilibrium theory into the study of IOs can pave the way for a promising IR research agenda.

    Mechanisms of Anion Reactions from the lab to ionospheres2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    A multitude of heavy neutral and ionic molecules have been discovered by the Cassini Plasma Spectrometer in the ionosphere of Saturn's largest moon Titan. However, only three cyano anions were explicitly identified there, namely CN-, C3N- and C5N-.  The identity of the heavier anions, which show an abundance maximum at m/z 1000, could, however, not be elucidated and   there is, so far, no clear explanation how these were generated.

    We investigated the reaction of the cyanide anion with methyl iodide using a velocity map imaging spectrometer setup and ab initio calculations. The data indicate a dominant direct rebound mechanism and a high internal excitation of the neutral product. According to the ab initio calculation two possible reaction pathways were expected, but in the experiment the two channels turned out to be indistinguishable due to low resolution.

    We also studied the reaction between C3N- and acetylene using three different experimental setups: a triple quadrupole mass spectrometer, a tandem quadrupole mass spectrometer, and the ''CERISES'' guided ion beam apparatus.

    The reaction showed three primary reaction pathways leading to C2H-, CN-, and C5N-. The production of C2H- could either happen via proton transfer or via formation of an adduct. The appearance of CN- could be explained by a reaction sequence involving an intermediate adduct but also via collision induced dissociation. Even though ab initio calculations predict two exoergic pathways leading to CN- and C5N-, all products are only accessible via energy barriers above 1 eV.

    In addition, we investigated the reaction between C5N- and acetylene. Also in this case the experimental and theoretical studies revealed that all reaction pathways proceed via energy barriers well above 1 eV. The sole exoergic pathway leading to C7N- has an energy barrier of 1.91 eV.  Since the chemistry in dark interstellar clouds and planetary ionospheres is restricted to exoergic reactions with energy barriers less than 20 meV or proceed in a barrier-less manner (Vuitton et al. Planetary and Space Science 57, 1558-1572 (2009)), none of the observed pathways are feasible growth mechanism in those environments.

    We also performed investigations of reactions between charged clusters with and without barriers using electrostatic models.  This led to the development of both approximate and exact expressions, which describe the sphere-sphere interaction and the electron transfer from a (neutral or charged) dielectric sphere to another charged dielectric sphere.  The exact solutions include sums that describe polarization effects to infinite orders. However, we have shown that these infinite sums can be simplified, and that these approximations can be applied to calculate the charge transfer cross-sections and Langevin-type cross-sections.

    Local plant species diversity in coastal grasslands in the Stockholm archipelago: The effect of isostatic land-uplift, different management and future sea level rise2017Independent thesis Advanced level (degree of Master (Two Years)), 30 poäng / 45 hpOppgave
    Abstract [en]

    Semi-natural grasslands with traditional management are known to be very species-rich, with many plant species strongly associated with the habitat. The last century’s decline of semi-natural grasslands, as a result of land use change and abandonment, has made the remaining semi-natural grassland a high concern for conservation. Since management can be costly and the available resources often are limited, it is important to use the most beneficial management method for preserving and enhancing the biodiversity. One semi-natural grassland type of certain interest around the Baltic region are coastal grasslands. In this study, I investigated vascular plant species occurrence in ten managed coastal grasslands located in the Stockholm archipelago. The effect of recent land-uplift and future sea level rise on the ten coastal grasslands were analyzed as well. A major part of all ten grasslands had been subjected to the process of isostatic land-uplift the past 100 years. Five of the grasslands were currently managed by grazing and the other five were managed by traditional mowing. There was no significant difference in alpha and gamma diversity between the two management types. Though, higher biodiversity values, such as more different species found in total, higher amount of species typically linked to meadows and pastures, less succession species and more red-listed species, were found in the traditionally mowed grasslands. Furthermore, a sea level rise with 40 cm the next 100 years in the region would lead to loss of plant species diversity in the investigated coastal grasslands. One major concern is the limited areas upwards on the coastal grasslands for species to migrate to in the future, which is expected to primarily affect species associated with meadows and pastures. The study highlights the importance of open and managed grassland areas further up the coastal grasslands for local species to migrate to, if the sea level would rise as predicted by future climate scenarios. Albeit weak the results of this study indicate that traditional mowing generates higher biodiversity values compared to grazing, hence it should be the preferred management method in coastal grasslands in the Stockholm archipelago.

    The body politics of the urban age: Reflections on surveillance and affect2018Inngår i: Palgrave Communications, ISSN 2055-1045, Vol. 4, nr 1, 2Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The article theorizes surveillance and affect in the context of urban security policy. Surveillance, as commonly understood, provides the means to “know” a person or a population, and to a certain extent to control or manage her/him/it. Hence, surveillance and knowledge are intimately tied together. New modes of surveillance are, therefore, also contingent upon new ways of knowing. This article discusses surveillance and affect in urban politics and let these concepts communicate with empirical research on urban security. The starting point is empirical research in three European cities on changes in local level security policy between 2000 and 2010. In all three cases, significant changes in the governance networks’ approaches about security were observed. These changes coincided with new developments in the use of surveillance technologies to increase feelings of security. In this process “performative” surveillance became a central aspect of urban security policy, with particular focus on affects related to fear of crime, old age, and gender. The article theorizes the relationship between security, surveillance, and affect. The argument put forward is that new security policies were instances of the production of a discourse in which the pre-cognitive, instinctual affects were increasingly targeted. The article shows how proponents of the new type of security governance articulate policy goals focusing on fear, threat, and surveillance. It contributes to a small body of literature on urban security and emotions by showing how cultural differences play out when similar policy goals that target citizens on the level of pre-cognitive affects are implemented.

    Abstract [en]

    Video surveillance in public space is common in contemporary urban environments. It is thought to be an effective deterrent against crime and terrorism. According to evaluation research, this is a false assumption. Yet cities and transport agencies continue to invest in video surveillance programs. This article uses public transport as a starting point to compare urban security governance in Berlin, Stockholm, and Warsaw. The aim is to explain the continuing diffusion of video surveillance as a tool in urban security policy. Particular focus is attributed to local policymakers’ understanding of goals and merits of video surveillance, and to the way that surveillance is legitimized. Results point towards a strong influence of privatization and commercialization of urban space in the diffusion of video surveillance. However, the degree in which citizens experience surveillance as threatening play a certain role as well, highlighting the crucial role of critical democratic citizenship.

    Perseverative Cognition as an Explanatory Mechanism in the Relation Between Job Demands and Sleep Quality.2017Inngår i: International Journal of Behavioral Medicine, ISSN 1070-5503, E-ISSN 1532-7558Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: The aim of this longitudinal three-wave study was to examine (i) reciprocal associations among job demands, work-related perseverative cognition (PC), and sleep quality; (ii) PC as a mediator in-between job demands and sleep quality; and (iii) continuous high job demands in relation to sleep quality and work-related PC over time.

    METHOD: A representative sample of the Swedish working population was approached in 2010, 2012, and 2014, and 2316 respondents were included in this longitudinal full-panel survey study. Structural equation modelling was performed to analyse the temporal relations between job demands, work-related PC, and sleep quality. Additionally, a subsample (N = 1149) consisting of individuals who reported the same level of exposure to job demands during all three waves (i.e. stable high, stable moderate, or stable low job demands) was examined in relation to PC and sleep quality over time.

    RESULTS: Analyses showed that job demands, PC, and poor sleep quality were positively and reciprocally related. Work-related PC mediated the normal and reversed, direct across-wave relations between job demands and sleep quality. Individuals with continuous high job demands reported significantly lower sleep quality and higher work-related PC, compared to individuals with continuous moderate/low job demands.

    CONCLUSION: This study substantiated reciprocal relations between job demands, work-related PC, and sleep quality and supported work-related PC as an underlying mechanism of the reciprocal job demands-sleep relationship. Moreover, this study showed that chronically high job demands are a risk factor for low sleep quality.

    ICT Support for The Thesis Process: A Case as a Literature Review2017Inngår i: European Distance and E-Learning Network 2017, www.eden-online.org , 2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Thesis supervision is one of the most complex and problematic pedagogical methods (Connell, 1985). Hansson and others discuss this complexity and show that the core activities of supervision require (an estimated) four to five times more effort per individual student than the payment/time allocated (Hansson, Larsson, & Wettergren, 2009). These authors also discuss the nature of thesis supervision and argue that large part of the process is dependent on communication. Communication is time-consuming and hence may be one of the reasons for this problematic state of affairs; maintaining the quality of communication is a challenge. The Department of Computer and Systems Sciences (DSV) faced this challenge when several theses were reviewed by the Swedish Authority of Higher Education (Bider & Jalali, 2016). The DSV had initiated a project to implement an ICT supported system for the thesis supervision process in 2011 in order to address the issue of quality. Sci-Pro, the thesis supervision support system, was launched in 2011 and has grown into a mature system during the last six years. There is a lack of comprehensive studies of ICT support systems; the aim of the current study is to conduct a literature review of the published articles about the DSV thesis supervision system to explore how ICT can support the thesis supervision process. The results of this study, therefore, offer benefits to individuals who intend to develop or use ICT support for the thesis process. Methodology

    ‘‘Allt har en negativ baksida också’’: En kvalitativ intervjustudie om unga kvinnors upplevelser av sociala medier och deras psykiska välmående2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna studie avser att, genom semistrukturerade intervjuer med unga kvinnor, studera kvinnornas egna upplevelser av de sociala medierna Facebook och Instagram, samt hur deras användning av dessa sociala medier eventuellt påverkar deras psykiska välmående. Detta förväntas bidra till en ökad förståelse om sociala mediers inverkan på människors hälsa. De teoretiska utgångspunkter som är centrala i denna studie är socialkonstruktivism, identitetsteori samt social jämförelseteori. Studien utgår från en fenomenologisk ansats vilket innebär att vi genom intervjuer ämnar studera kvinnornas subjektiva livsvärld utifrån deras egna erfarenheter och upplevelser kring ämnet sociala medier. Vi har genomfört semistrukturerade intervjuer med åtta kvinnor i åldern 18-25 år, där en form av snöbollsurval har använts. Vidare har en tematisk analys genomförts, där teman identifierades utifrån vad som framkom i intervjumaterialet, som i sin tur analyserades i relation till de teoretiska utgångspunkterna samt tidigare forskning. Studiens resultat visar att det bland informanterna finns en stor variation i upplevelser av sociala medier som innefattar både positiva och negativa aspekter. Vidare framkom det att samtliga informanter upplevt att deras psykiska välmående påverkats av de sociala medierna Facebook och Instagram. Men hur och i vilken utsträckning de upplever sig ha blivit påverkade anger de främst berott på det dagliga humöret. Utifrån kvinnornas upplevelser gällande hur deras psykiska välmående påverkas av de sociala medierna, framträder känslor såsom avundsjuka och otillräcklighet kopplat till att de jämför sig med andra. Ur detta framträder känslor kring att vara missnöjd med sig själv och sin tillvaro, vilket i sin tur påverkar kvinnornas syn på sig själva. Kvinnornas upplevelser tolkades utifrån Giddens identitetsteori, då kvinnorna berättade om att de framställer och granskar sig själva och sina identiteter i förhållande till andra personer i dessa sociala medier. Att kvinnorna jämförde sig med andra och hur detta inverkade på psykiskt välmående tolkades utifrån Festingers sociala jämförelseteori. Vidare kunde den medvetenhet kring normer och beteenden som kvinnorna upplever konstrueras genom sociala medier tolkas i relation till socialkonstruktivismen. Detta har lett fram till en ny kunskap och ökad förståelse om sociala mediers påverkan på unga kvinnors psykiska välmående. Däribland att det finns en medvetenhet gällande sociala mediers påverkan samt hur denna påverkan visade sig vara högst individuell och föränderlig utifrån dess subjektiva kontext.

    Vem litar på domstol och polis? En kvantitativ studie om sambandet mellan tillit och etniskt ursprung2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Tillit har en fundamental betydelse i ett samhälle. Förtroende för förvaltningsinstitutioner såsom domstol och polis är en viktig del för att samhället ska fungera väl. Denna studie ämnar att undersöka förtroendet för domstol och polis i Sverige och hur detta eventuellt skiljer sig mellan grupper med olika etniska ursprung. Detta med utgångspunkt från Robert Putnams teori om socialt kapital. Putnam benämner begreppet socialt kapital som en viktig beståndsdel för tillit i ett samhälle, och detta sociala kapital skiljer sig mellan samhällen världen över. På så vis så har den komparativa delen uppkommit för att se skillnader i tillit mellan olika etniska ursprung. Etniska ursprung är i det här arbetet uppdelat i grupperna Sverige, Norden, Europa och utanför Europa. Analyserna kontrollerar för första och andra generationens invandrare inom dessa etniska gruppindelningar. Förtroendet för domstol och polis undersöks utifrån tre aspekter: generellt förtroende, förtroende om opartiskt och rättvist agerande inom domstol och polis samt förtroende gällande domstol och polis ställer alla lika inför lagen. Dessa tre aspekter har valts utifrån Bo Rothsteins teori om vad som grundar förtroende för institutioner. Detta är en kvantitativ studie som baseras på ett datamaterial från European Social Survey 2010. För att analysera materialet användes linjär regressionsanalys och korstabeller. Resultatet visar att andra generationens invandrare från Europa och utanför Europa har lägre generellt förtroende för polisen jämfört med etniskt svenska. Första och andra generationens invandrare har lägre förtroende för att polisen agerar opartiskt och rättvist jämfört med etniskt svenska, medan första generationens invandrare har lägre förtroende för det samma när det gäller domstol. Resultatet visar också att etniskt svenska har lägre förtroende för att polisen ställer alla lika inför lagen jämfört med första och andra generationens invandrare med ursprung Europa och utanför Europa. Studiens slutsats är att etniskt ursprung har en inverkan på förtroendet inom alla etiska aspekter för polis och inom en aspekt inom domstol. På så vis tycks polisväsendet leva upp till de etiska normerna i lägre grad jämfört med domstolsväsendet.

    Ledarskapet i förskolan: Förskolechefer med ansvar för flera förskolor2017Independent thesis Advanced level (degree of Master (One Year)), 40 poäng / 60 hpOppgave
    Abstract [sv]

    Då samhället har förändrats och även påverkat förskolans värld kan det idag vara så att en förskolechef ansvarar för flera förskolor. Det kan betyda att förskolechefen får svårt att hinna med att besöka förskolorna och pedagogerna som är verksamma där. Syftet är att studera ledarskapet på några av förskolorna. Min frågeställning handlar om hur förskolechefen beskriver ledarskapet och hur pedagogerna beskriver ledarskapet i förskolan där förskolechefen inte sitter placerad. Vad har de anställda och deras chef för uppfattningar om ledarskapet i förskolan? Studien har gjorts utifrån en kvalitativ metod med tio intervjuer med förskolechefer, ledningsgrupp med arbetslagsledare, utvecklare och pedagoger på fältet. Metodansatsen görs med fältforskning med intervjuer och deltagande observationer och fältanteckningar. Ett resultat som visar att förskolecheferna fortfarande är belastade med administration och har som mål att bli mer pedagogiska ledare på fältet. En pedagogisk utvecklare behöver bli flera för att hinna möta upp pedagogerna på fältet. Arbetslagsledarna har antingen valt bort uppdraget och de som är kvar har fått mer administration och fler förskolor att besöka. Analysen synliggör ett förändringsarbete som förskolecheferna står inför och med ett transformativt och samproducerat ledarskap leder förskolecheferna organisationen framåt. Diskussionen synliggör en brist på förutsättningar, frågor som inte ställs leder heller inte till effektiva förändringar och långa avstånd skapar fortfarande ett fysiskt distanserat ledarskap. Praktiken ska fortgå och utvecklingen ska drivas framåt vilket görs med ett meningsskapande och en vision om delaktighet för alla verksamma inom förskolan.

    Kvinnors karriärväg till chef i Svenska kyrkan2017Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this work has been to illustrate the career of executive women working in the organization Church of Sweden. Nine female directors where interviewed by using qualitative method. Seven were vicars working as head director or managing director. Two worked as administrative directors. The issue was about possibilities in the work and obstacles along the journey to the position. How did the women view their career to executive?The theoretical perspective in this work was leadership and gender theory.Some themes appeared: to trust your own competence, empowerment, developing the organizational work, to review and responsibility, challenge and learning and to have dared the career step may continue the career. The result showed that a person who is encouraged by others gets a stronger desire to apply for an executive position. Also, the female executives saw possibilities in working ‘as a we’, together with the coworkers. They had experienced that self confidence is necessary for a woman working as a director in an organization where the norm has been male. This work may contribute to the aim in organizations to get a diversity and a parity in executive positions. The scientific and pedagogical aim of the studie is to develop and deliver knowledge about obstacles and possibilities in career advancement to executive.

    Det ansvarsfulla mötet: En närhetsetisk analys av omsorgens innebörder i förskolan2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This doctoral thesis embraces Care in the discipline of Early Childhood Education. In this thesis, the concept of responsibility is used to analyze the meaning of care in preschool. The scientific problem can be expressed as follows: How is it possible to grasp the aspects of responsibility in relation to the preschool and preschool teachers’ and staff’s mission in general, and as an expression of meaning of care and practices in particular?

    In order to construct new knowledge on this particular care responsibility in preschool, a theory of ethics is required. Such a theory of ethics cannot be derived solely from general ethical principles or rules, but need to put the emphasis on how people's relationships and mutual dependencies develop and can be maintained in a manner as to uphold that what is good and works in the relationship (Henriksen & Vetlesen, 2013). Against this background, the proximity ethical theory is particularly suitable as an analytical tool box for this thesis. It is represented in my work by Arne Johan Vetlesen, Zygmunt Bauman and Per Nortvedt. The proximity ethics is referred to as an experience-based ethics based on interpersonal practice. It is in this interpersonal practice that we meet the notions of duty and responsibility, respect and care.

    The thesis reflects a specific socio-historical era in preschool history: two breaking points, one in the 1990s and the other in the early 2000s. The thesis’ empirical material consists of analyses, partly from individual interviews that were collected during the period 1993-1995, and partly from focus group interviews gathered in the period 2004-2006.

    The purpose of this study is, by using a proximity ethical approach, to generate knowledge about meaning of care and practices by studying preschool teacher’s speech concerning responsibility during two different time periods: the period just before and just after the introduction of the Curriculum for the Preschool in Sweden (Lpfö98). The following research questions have been formulated for the work: How do preschool staff speak about the expressions of responsibility and the boundaries of responsibility in the preschool’s everyday life? In what way does a theory of care and the proximity ethical perspective contribute to a broader understanding of the meaning of care in preschool and the teaching profession’s ethical dimension, during the current periods of time and in a contemporary perspective?

    The interviews 1993-1995 reveals the following themes as examples of expressions of responsibility and boundaries of responsibility: Control and safety, Flexibility respectively Division of responsibility between preschool and parents, Family support: Information, solidarity and relief. Focus group interview 2004-2006 reveals the following themes as examples of expressions of responsibility and boundaries of responsibility: Peace and quiet, To pay attention to the children respectively The tension between service and educational activity, Family support: To maintain good relationships.

    In conclusion, the challenges that emerge when making the concept of care more visible in pre-school practice are discussed. These challenges are reflected on the basis of an analytical idea of responsibility in the encounter with the other. Furthermore, it is examined how the proximity ethical perspective can be used as a springboard for a contemporary and forward-looking discussion of the meaning of care in preschool and the pedagogical profession’s ethical dimensions.

    The amyloid-β precursor protein (APP)-binding protein Fe65 and APP processing2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by abnormal deposition of neurotoxic amyloid-β (Aβ) peptide. Aβ is generated by sequential cleavage of the amyloid-β precursor protein (APP) by β- and then γ-secretase. However, APP can also be processed by α- and γ-secretase, instead resulting in generation of neuroprotective sAPPα. Increased APP phosphorylation and altered expression levels of the brain enriched Fe65 protein have been observed in the brains of AD patients. Fe65 can not only interact with membrane tethered APP, but can also localized into the nucleus and act as a transcriptional regulator together with the APP intracellular domain (AICD), generated after γ-secretase processing. How APP processing, APP/Fe65 interaction, and the nuclear AICD/Fe65 complex is regulated has not yet been fully understood. The aim of this thesis was therefore to further elucidate how Fe65 is regulated and how APP Ser675 phosphorylation affects APP processing.

    We could identify several factors regulating Fe65. First, we identified that neuronal differentiation induces Fe65 phosphorylation (paper I), and that phosphorylated forms of Fe65 were preferentially localized outside the nucleus (paper II). Second, we found that the APP binding PTB2 domain of Fe65, rather than the previously proposed N-terminal WW domain, is important for the nuclear localization of Fe65 (paper II). In addition, we surprisingly found that mutation of S228 in the Fe65 N-terminus could increase the APP/Fe65 interaction (paper III). Third, both α- and γ-secretase inhibitors decreased Fe65 nuclear localization similarly, indicating an important role of α-secretase in regulating Fe65 nuclear localization (papers II and III). Lastly, we could in paper IV for the first time show that phosphorylation of APP at Ser675 regulates APP processing at the plasma membrane, resulting in reduced levels of sAPPα. These results, together with the observation that APP Ser675 phosphorylation occur in AD brains, suggest that Ser675 phosphorylation could contribute to AD pathology by decreasing α-secretase processing and instead increasing the levels of Aβ.

    In summary these studies have contributed to understanding of APP processing and the interplay between Fe65 and APP, two suggested key players in AD.

    Relationship between shift work and the onset of rheumatoid arthritis.2017Inngår i: RMD open, ISSN 2056-5933, Vol. 3, nr 2, e000475Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Environmental factors play a prominent role in rheumatoid arthritis (RA) aetiology. Shift work has previously been associated with increased RA risk in females. The aim of this study was to investigate the potential association, including a dose-response association, between permanent night shift work, rotating shift work and day-oriented shift work and risk of developing anticitrullinated peptide antibodies (ACPA)-positive and ACPA-negative RA.

    Methods: The present report is based on a population-based, case-control study with incident cases of RA (1951 cases and 2225 controls matched by age, gender and residential area). Using logistic regression, occurrence of RA among subjects who have been exposed to different kinds of shift work was compared with that among those who have never been exposed by calculating the OR with a 95% CI.

    Results: Rotating shift work and day-oriented shift work increased the risk of developing ACPA-positive RA (OR 1.3, 95% CI 1.0 to 1.7 and OR 1.3, 95% CI 1.0 to 1.6), but not ACPA-negative RA. Permanent night shift work appeared to be a protective factor both against ACPA-positive RA (OR 0.7, 95% CI 0.6 to 0.9) and ACPA-negative RA (OR 0.8, 95% CI 0.6 to 1.0). For both subsets of RA, significant trends showed a lower risk of developing RA with increasing duration of permanent night shift work (p value for trend 0.002 vs 0.04).

    Conclusions: Sleep restriction as a consequence of shift work is associated with several biological effects among which changes in melatonin production may be involved. The present epidemiological findings of a complex relationship between sleep patterns and different forms of RA may be of importance for increasing the understanding of the pathophysiology of RA.

    Total workload and recovery in relation to worktime reduction: a randomised controlled intervention study with time-use data.2017Inngår i: Occupational and Environmental Medicine, ISSN 1351-0711, E-ISSN 1470-7926, oemed-2017-104592Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: A 25% reduction of weekly work hours for full-time employees has been shown to improve sleep and alertness and reduce stress during both workdays and days off. The aim of the present study was to investigate how employees use their time during such an intervention: does total workload (paid and non-paid work) decrease, and recovery time increase, when work hours are reduced?

    METHODS: Full-time employees within the public sector (n=636; 75% women) were randomised into intervention group and control group. The intervention group (n=370) reduced worktime to 75% with preserved salary during 18 months. Data were collected at baseline, after 9 months and 18 months. Time-use was reported every half-hour daily between 06:00 and 01:00 during 1 week at each data collection. Data were analysed with multilevel mixed modelling.

    RESULTS: Compared with the control group, the intervention group increased the time spent on domestic work and relaxing hobby activities during workdays when worktime was reduced (P≤0.001). On days off, more time was spent in free-time activities (P=0.003). Total workload decreased (-65 min) and time spent in recovery activities increased on workdays (+53 min). The pattern of findings was similar in subgroups defined by gender, family status and job situation.

    CONCLUSIONS: A worktime reduction of 25% for full-time workers resulted in decreased total workload and an increase of time spent in recovery activities, which is in line with the suggestion that worktime reduction may be beneficial for long-term health and stress.

    Abstract [sv]

    Det Egyptiska sekelskiftet var minst lika omvälvande som det Franska, och Aghili lyckas även i Egypten gravitera mot händelsernas centrum. Trots att Aghili befinner sig i Kairo under vad som kommit att kallas den islamiska renässansen, och att han själv kan sägas vara engagerad i en av tidens reformrörelser, gapar forskningen om denna tid i hans liv av stora hål. Religionshistorikern Frédéric Brusi kontextualiserar i sitt bidrag Aghilis religiopolitiska verksamhet i Egypten, men pekar också på en rad oklarheter i Aghilis biografi, oklarheter som öppnar mot nya forskningsfält.

    Den Andre i svenska valmanifest: En kvalitativ studie av svenska valmanifest och andrafiering inom politisk diskurs2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna uppsats är en studie i hur andrafiering används inom Socialdemokraternas och Moderaternas valmanifest, med syfte att se hur det har använts i diskurser inom politisk kommunikation gentemot potentiella väljare, utifrån frågeställningar om vilken funktion det fyller och hur användningen har utvecklats över tid. Vidare lyfts också frågor om hur andrafiering som process går till och vilka som har kommit att konstrueras som Den Andre. För att kunna studera den politiska diskursen har jag utöver teorier om andrafiering och Den Andre, främst använt mig av Laclau & Mouffes diskursteori, som har ett socialkonstruvistiskt perspektiv på språk och diskurs, för att förstå vilka effekter den politiska diskursen kan ha för samhället. Datamaterialet bestod av Socialdemokraternas och Moderaternas valmanifest inför svenska riksdagsval under en 50-års period, från 1964–2014, med totalt 32 valmanifest. Texterna har kodats och analyserats med en kvalitativ innehållsanalys. Resultatet visar på hur det skett en förändring över tid i vilka som andrafieras i valmanifesten, och att även användningen har ändrat karaktär och kommit att få ett allt större utrymme i den politiska diskursen i valmanifesten.

    Fund Our Future & Fees Must Fall: En komparativ fallstudie om två studentprotester2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Studiens syfte är att se hur sociala rörelser och stater interagerar, samt hur dialogen ser ut inom respektive part. Frågeställningarna som syftar till att fånga det är således; Hur ser relationen mellan sociala rörelser och stater ut, och hur påverkar var sidas val av strategier motpartens handlingsmönster? Samt; Vilka interna strategier inom kampanj respektive stat är mest framträdande? För att undersöka det har två kampanjer valts ut, Fees Must Fall i Sydafrika och Fund Our Future i Storbritannien. Vidare har nyhetsartiklar valts från sammanlagt nio av ländernas mest lästa nyhetstidningar. Fyra teoretiska ingångar fått vägleda analysarbetet; radical flank effect, symbolic damage, protest policing och eventful protest. Dessa är alla analytiska verktyg som hjälper oss förstå de mångfacetterade dimensionerna som existerar parallellt inom sociala rörelser och statens arbete. Den samlade tidigare forskningen har utforskat specifika delar av de nämnda begreppen, men däremot har aspekternas samverkande förmåga inte tidigare studerats.

    Studiens resultat visar att våldsamma aktioner ofta leds av radikala demonstranter. Dessa leder ofta inte enbart till stor medial uppmärksamhet, utan kan beroende på kontext förändra sociala rörelser och statens interna strategiska struktur. Det innebär även att fredliga aktioner ofta hamnar i skymundan, vilket bidrar till att befästa uppfattningen om att våld krävs för att sociala rörelsers syfte ska synas. Även stater kan uppleva sig nödgade att använda våldsamma strategier i mötet med demonstranter. Vidare visar resultaten på att det finns en interaktiv dynamik mellan kampanjer och stater, som även visar på aktörskap inom respektive part.

    Co-opting Religion: How ruling populists in Turkey and Macedonia sacralise the majority2017Inngår i: Religion, State and Society, ISSN 0963-7494, E-ISSN 1465-3974, ISSN 0963-7494 (Print) 1465-3974 (Online)Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Despite the remarkable scholarly attention to populism and popu- list parties, the relation between populism and religion remains understudied. Using evidence from two long-term ruling populist parties – Turkey’s Justice and Development Party and Macedonia’s Internal Macedonian Revolutionary Organisation-Democratic Party for Macedonian National Unity – this study focuses on how and why religion can be an instrument for populist politics at three levels: (i) discursive, (ii) public policy and (iii) institutionalised alliances with religious authorities. The study highlights that reli- gion comes into play at these three levels once populists attain comfortable electoral margins but encounter mounting political and economic challenges that can potentially weaken their grip on power. Ruling populists co-opt and monopolise the majority religion in the name of ‘the people’s will’ as they increasingly undermine democratic legitimacy but they need to justify their systematic crackdown on dissent, the system of checks and bal- ances, the rule of law and minorities. The empirical findings of the study also demonstrate the dual function of religion for populists: its catch-all potential to create cross-class and cross-ethnicity pop- ular support, and its instrumentality to discredit dissent as ‘reli- giously unfit’ while constructing an antagonism of ‘the people’ versus ‘the elites’.

    Energetic processing of complex molecules in the gas phase2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Collisions between molecules and gas phase targets often lead to various intriguing processes. Such collisions may induce fragmentation of molecules that can be divided into different subsets depending on the projectile, target, and collision energy. One major part of the present research is the exploration of astrophysical relevant collision mechanisms. In collisions between polycyclic aromatic hydrocarbon (PAH) molecules or fullerenes with, for example, helium, nuclear stopping can lead to the prompt knockout of a carbon atom from the molecule. Such a vacancy in the molecular carbon backbone can be highly reactive, and lead to the formation of larger molecules. The energy dependencies of such processes are important for the understanding of astrochemical molecular growth processes, which in turn may lead to the formation of larger and more complex molecules in space. In addition, hydrogenation of PAHs changes their structures and internal properties, including their resistance against fragmentation. To better understand the effects of hydrogenation on the fragmentation of PAHs, low energy photofragmentation experiments are presented along with the collision experiments, and a detailed comparison is made between the effects of these different types of energy transfer processes.

    Besides astrophysically relevant research, studies on the response of biomolecules to collisions with gas phase targets are presented. Here, the energy dependence for formation of the protonated n-butyl β-ionone Schiff base through electrocyclization of the protonated n-butylamine Schiff base of all-trans-retinal in collisions is presented. The latter is a model compound for all-trans-retinal, the chromophore of the light sensitive opsin proteins, and such studies are essential for the understanding of the operation of mammal vision.

    While our collision studies are very successful, they are sometimes also limited by the experimental timescale. Therefore, we have constructed an experimental setup for ion storage and fragmentation analysis. The goal of this new experiment is to store internally hot fragments to investigate their behavior on extended timescales and as functions of internal excitation energies.

    The Use of N,P-Iridium and N,P-Palladium Complexes in Asymmetric Synthesis2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The work presented in this thesis concerns asymmetric catalysis using chiral N,P-ligands and iridium or palladium transition metals. The first part  (Chapters 2 and 3) highlights the N,P-iridium catalyzed asymmetric hydrogenation of 1,4-cyclohexadienes having functionalized or unfunctionalized substituents, including allylsilane side chains. A series of N,P-iridium catalysts were synthesized and screened on a number of cyclohexadienes. The developed N,P-iridium catalysts have provided excellent chemo-, regio- and enantioselectivity for most of the products obtained. For substrates having an allylsilane sidechain, the chiral cyclic allylsilane products were used to induce stereocontrol in a subsequent Hosomi-Sakurai reaction using TiCl4 as Lewis acid and aldehydes as electrophiles. The corresponding homoallylic alcohols were obtained in good to excellent diastereoselectivity. 

    The second part (Chapter 4) describes the N,P-iridium catalyzed asymmetric hydrogenation of various vinyl fluorides. A number of tri- and tetrasubstituted vinyl fluorides were synthesized and evaluated for the asymmetric hydrogenation. The corresponding saturated chiral fluoro compounds were obtained in very high enantioselectivity (up to 99% ee). The defluorination, usually known to occur under the catalytic hydrogenation conditions, were not observed for the majority of the substrates. 

    Finally, Chapter 5 describes the application of N,P-ligands in the asymmetric cycloisomerization of 1,6-enynes using a palladium precatalyst. The enantioselectivities for the products were found to depend both on the substrate as well as the hydrogen source. These developed catalytic reactions provide attractive methods to create multiple stereogenic centers in a molecule in relatively few steps from readily available starting materials.

    The Vulnerability of the Great Lakes Region to Waterborne Diseases in the Wake of Climate Change: A Literature Review2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Clean drinking and recreational water is essential for human survival and contaminated water cause 1.4 million deaths worldwide every year. Both developing and developed countries suffer as a consequence of unsafe water that cause waterborne diseases. The Great Lakes region, located in the United States is no exception. Climate change is predicted to cause an increase in waterborne disease outbreaks, worldwide, in the future. To adapt to this public health threat, vulnerability assessments are necessary. This literature study includes a vulnerability assessment that describes the main factors that affect the spreading of waterborne diseases in the Great Lakes region. Future climate scenarios in the region, and previous outbreaks are also described. The study also includes a statistical analysis where mean temperature and precipitation is plotted against waterborne disease cases. The main conclusion drawn is that the Great Lakes region is at risk of becoming more vulnerable to waterborne diseases in the future, if it does not adapt to climate change.

    The LENATM system applied to Swedish: Reliability of the Adult Word Count estimate2017Inngår i: Proceedings of the 18th Annual Conference of the International Speech Communication Association (INTERSPEECH 2017) / [ed] Marcin Wlodarczak, STockholm: The International Speech Communication Association (ISCA), 2017, 2088-2092 s., 1287Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The Language Environment Analysis system LENATM is used to capture day-long recordings of children’s natural audio environment. The system performs automated segmentation of the recordings and provides estimates for various measures. One of those measures is Adult Word Count (AWC), an approximation of the number of words spoken by adults in close proximity to the child. The LENA system was developed for and trained on American English, but it has also been evaluated on its performance when applied to Spanish, Mandarin and French. The present study is the first evaluation of the LENA system applied to Swedish, and focuses on the AWC estimate. Twelve five-minute segments were selected at random from each of four day-long recordings of 30-month-old children. Each of these 48 segments was transcribed by two transcribers,and both number of words and number of vowels were calculated (inter-transcriber reliability for words: r = .95,vowels: r = .93). Both counts correlated with the LENA system’s AWC estimate for the same segments (words: r = .67, vowels: r = .66). The reliability of the AWC as estimated by the LENA system when applied to Swedish is therefore comparableto its reliability for Spanish, Mandarin and French.

    ”Men självklart är flickorna oerhört mer utsatta”: En vinjettstudie om gymnasielärares uppfattning om och agerande kring pojkar i en hederskontext2017Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The aim of this study is to examine how boys, in the context of honour, are perceived by teachers and what kind of efforts are being taken in specific situations. The study is based on seven qualitative interviews with high school teachers, from four different schools in the Stockholm County, using five vignettes. The interviews were processed using a thematic analysis and the result was analysed with the help of Christie’s theory about ideal and non-ideal victims, the theory of street-level bureaucracy and to some extent pathological altruism. The results show that the teachers in general find it easier to define girls as victims rather than boys. The teachers themselves think the reason for that can be that boys are perceived to have more power over their own situation and a freedom that the girls lack. Loud and aggressive behavior complicates the boy’s victimhood further. Reports of concern to Social services are rarely mentioned and is to be taken care of by school counselors or principals. The teachers defined it as the process, but also expressed a feeling of lack of knowledge and in some cases an unwillingness to act due to a fear of prejudging.

    Distributed Intelligence-Assisted Autonomic Context-Information Management: A context-based approach to handling vast amounts of heterogeneous IoT data2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    As an implication of rapid growth in Internet-of-Things (IoT) data, current focus has shifted towards utilizing and analysing the data in order to make sense of the data. The aim of which is to make instantaneous, automated, and informed decisions that will drive the future IoT. This corresponds to extracting and applying knowledge from IoT data which brings both a substantial challenge and high value. Context plays an important role in reaping value from data, and is capable of countering the IoT data challenges. The management of heterogeneous contextualized data is infeasible and insufficient with the existing solutions which mandates new solutions. Research until now has mostly concentrated on providing cloud-based IoT solutions; among other issues, this promotes real-time and faster decision-making issues. In view of this, this dissertation undertakes a study of a context-based approach entitled Distributed intelligence-assisted Autonomic Context Information Management (DACIM), the purpose of which is to efficiently (i) utilize and (ii) analyse IoT data.

    To address the challenges and solutions with respect to enabling DACIM, the dissertation starts with proposing a logical-clustering approach for proper IoT data utilization. The environment that the number of Things immerse changes rapidly and becomes dynamic. To this end, self-organization has been supported by proposing self-* algorithms that resulted in 10 organized Things per second and high accuracy rate for Things joining. IoT contextualized data further requires scalable dissemination which has been addressed by a Publish/Subscribe model, and it has been shown that high publication rate and faster subscription matching are realisable. The dissertation ends with the proposal of a new approach which assists distribution of intelligence with regard to analysing context information to alleviate intelligence of things. The approach allows to bring few of the application of knowledge from the cloud to the edge; where edge based solution has been facilitated with intelligence that enables faster responses and reduced dependency on the rules by leveraging artificial intelligence techniques. To infer knowledge for different IoT applications closer to the Things, a multi-modal reasoner has been proposed which demonstrates faster response. The evaluations of the designed and developed DACIM gives promising results, which are distributed over seven publications; from this, it can be concluded that it is feasible to realize a distributed intelligence-assisted context-based approach that contribute towards autonomic context information management in the ever-expanding IoT realm.

    A note on “shaved dice” inferenceInngår i: American Statistician, ISSN 0003-1305, E-ISSN 1537-2731Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Two dice are rolled repeatedly, only their sum is registered. Have the two dice been “shaved”, so two of the six sides appear more frequently? Pavlides & Perlman (2010) discuss this somewhat complicated type of situation through curved exponen- tial families. Here we contrast their approach by regarding data as incomplete data from a simple exponential family. The latter, supplementary approach is in some respects simpler, it provides additional insight about the relationships among the likelihood equation, Fisher information, and the EM algorithm, and it illustrates the information content in ancillary statistics.

    Crafting Movement: Moving Image Collections for Interaction Design2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis conceptualises, investigates, and reflects on the moving image design space in Human-Computer Interaction (HCI). Motivated by the increasing number of videos, films, and animations produced in the field, the thesis recognizes moving image making as a designerly way of inquiry across research and practice, and argues for the importance of moving image as a research topic in interaction design. 

    The first contribution of this thesis is the conceptualization of the moving image design space. The growing body of moving images, varying in forms and purposes, can be held together to establish a foundation of knowledge that informs and generates new research and practice. We identify four collections of existing works and their different roles, namely moving image as design technique, design element, design exhibit, and design promotion. The second contribution is the manifestation of moving image making through concrete design studies. These exemplars empirically demonstrate how they investigate, enrich, and challenge the four established collections, and ultimately expand the moving image design space. 

    These contributions not only provide new knowledge on moving images for better understanding their various roles in interaction design and making works that respond to emerging design opportunities, but also foreground the discussion on the mediation aspect of moving image in HCI.
