    The Making of Home and History: The Revival of the Fin de Siècle Architecture2020In: Home Cultures, ISSN 1740-6315, E-ISSN 1751-7427Article in journal (Refereed)
    Abstract [en]

    In this text, I will discuss how history is used and understood in different contemporary contexts regarding the domestic architecture of the fin de siecle (approx. 1880-1915). The focus is on apartment housing and my examples are all found in central Stockholm. I have used an ethnographical method with personal stories and experiences as my main focus while conducting interviews with people living in apartments in houses originally built around 1900. To place the interviews in a broader context they have been analyzed in relation to contemporary housing advertisements. In the first part of the article fin de siecle architecture is discussed as a coherent material style, modified to modern needs and dreams and given the function of a sign of among other things history, quality and status, legitimizing new modern lifestyles. In the second part, the use of history is considered as one among many factors in the project of homemaking and as being a possibility to transform yourself and your surroundings into better and more beautiful and interesting versions.

    Targeted Mutations in the ATR Pathway Define Agent-Specific Requirements for Cancer Cell Growth and Survival2012In: Molecular Cancer Therapeutics, ISSN 1535-7163, E-ISSN 1538-8514, Vol. 11, no 1, p. 98-107Article in journal (Refereed)
    Abstract [en]

    Many anticancer agents induce DNA strand breaks or cause the accumulation of DNA replication intermediates. The protein encoded by ataxia-telangiectasia mutated and Rad 3-related (ATR) generates signals in response to these altered DNA structures and activates cellular survival responses. Accordingly, ATR has drawn increased attention as a potential target for novel therapeutic strategies designed to potentiate the effects of existing drugs. In this study, we use a unique panel of genetically modified human cancer cells to unambiguously test the roles of upstream and downstream components of the ATR pathway in the responses to common therapeutic agents. Upstream, the S-phase-specific cyclin-dependent kinase (Cdk) 2 was required for robust activation of ATR in response to diverse chemotherapeutic agents. While Cdk2-mediated ATR activation promoted cell survival after treatment with many drugs, signaling from ATR directly to the checkpoint kinase Chk1 was required for survival responses to only a subset of the drugs tested. These results show that specifically inhibiting the Cdk2/ATR/Chk1 pathway via distinct regulators can differentially sensitize cancer cells to a wide range of therapeutic agents.

    Anställningsintervju på ett andraspråk: Ett nålsöga2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    En anställningsintervju är en situation där språkkunskapen sätts på prov, särskilt om intervjun ska genomföras på den arbetssökandes andraspråk. Med detta arbete har jag velat undersöka hur arbetssökande akademiker med ett andraspråk respektive presumtiva arbetsgivare såg på språkkunskapen hos de arbetssökande. Jag ville också veta vilka språkliga aspekter och vilka andra dialogsituationer som gav upphov till oklarheter i kommunikationen samt vilka strategier som användes för att underlätta kommunikationen. Detta ville jag undersöka för att få en indikation vad sfi-undervisningen bör fokusera på för att gynna elevernas möjligheter att genomföra en anställningsintervju på ett bra sätt.

    Materialet som användes är två enkäter en för skattning av de arbetssökandes anställningsbarhet ur ett språkligt perspektiv, och en för rangordning av språkliga aspekter hos de arbetssökande. Dessutom analyserades två inspelade och transkriberade fingerade anställningsintervjuer samt monologinspelningar där de arbetssökande reflekterade över anställningsintervjuer.

    Resultaten visar undervisningen bör ha ett brett perspektiv på språket. Ordkunskap och uttal är två viktiga aspekter där undervisningen noggrant måste prioriteras. Mycket muntlig träning bör erbjudas, gärna i samarbete med modersmålstalare i rekryterande positioner och gärna om temat anställningsintervjuer för att medvetandegöra eleverna om vilka språkkunskaper som behöver tränas. Fingerade anställningsintervjuer liknande dem som denna studie bygger på kan vara en utmärkt utgångspunkt för temaarbete kring anställningsintervjuer.

    The Intergenerational Assimilation of Completed Fertility: Comparing the Convergence of Different Origin Groups2019In: The international migration review, ISSN 0197-9183, E-ISSN 1747-7379, Vol. 53, no 2, p. 429-457Article in journal (Refereed)
    Abstract [en]

    Recent studies have highlighted the need for new research on intergenerational assimilation and how it varies for different origin groups. This article responds by studying the intergenerational assimilation of completed fertility in the United Kingdom. The results provide evidence of assimilation for some origins, in particular for women from Ireland and Jamaica. Yet results also show evidence against assimilation for second-generation Pakistanis and Bangladeshis. The ability of the method used to distinguish between origin groups highlights the importance of a robust statistical approach that takes account of heterogeneity, an approach that can also be used to study outcomes other than fertility.

    Residential segregation and the fertility of immigrants and their descendants2018In: Population, Space and Place, ISSN 1544-8444, E-ISSN 1544-8452, Vol. 24, no 3, article id e2098Article in journal (Refereed)
    Abstract [en]

    Measures of community population composition, such as residential segregation, are important theoretical mechanisms that have the potential to explain differences in fertility between immigrants, their descendants, and destination natives. However, only a handful of studies explore these mechanisms, and most are limited by the fact that they carry out cross-sectional analysis. This study proposes a new approach, which focuses on community composition in childhood. It uses longitudinal census data and registered births in England and Wales to investigate the relationship between completed fertility and multiple measures of community composition, including residential segregation. The results show that the fertility of immigrants is closer to native fertility if they grow up in less segregated areas. This provides evidence in support of the childhood socialisation hypothesis. Furthermore, residential segregation explains some of the variation in completed fertility for second-generation women from Pakistan and Bangladesh, the only second-generation group to have significantly higher completed fertility than natives. This suggests one reason why the fertility of some South Asians in England and Wales may remain culturally entrenched. All of these findings are consistent for different measures of community composition. They are also easier to interpret than the results of previous research because exposure is measured before childbearing has commenced, therefore avoiding many issues relating to selection, simultaneity, and conditioning on the future.

    Submillimeter emission from water in the W3 region2003In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 402, p. L59-L62Article in journal (Refereed)
    Abstract [en]

    Using the Odin satellite, we have mapped the submillimeter emission from the 110-101 transition of ortho-water in the W3 star-forming region. A 5arcminx 5arcmin map of the W3 IRS4 and W3 IRS5 region reveals strong water lines at half the positions in the map. The relative strength of the Odin lines compared to previous observations by SWAS suggests that we are seeing water emission from an extended region. Across much of the map the lines are double-peaked, with an absorption feature at -39 km s-1; however, some positions in the map show a single strong line at -43 km s-1. We interpret the double-peaked lines as arising from optically thick, self-absorbed water emission near the W3 IRS5, while the narrower blue-shifted lines originate in emission near W3 IRS4. In this model, the unusual appearance of the spectral lines across the map results from a coincidental agreement in velocity between the emission near W3 IRS4 and the blue peak of the more complex lines near W3 IRS5. The strength of the water lines near W3 IRS4 suggests we may be seeing water emission enhanced in a photon-dominated region. Based on observations with Odin, a Swedish-led satellite project funded jointly by the Swedish National Space Board (SNSB), the Canadian Space Agency (CSA), the National Technology Agency of Finland (Tekes), and Centre National d'Études Spatiales (CNES). The Swedish Space Corporation was the industrial prime contractor and is also responsible for the satellite operation.

    Upper limits to the water abundance in starburst galaxies2007In: Astronomy & Astrophysics, ISSN 0004-6361, Vol. 469, p. 121-124Article in journal (Refereed)
    Abstract [en]

    Aims.We have searched for emission from the 557 GHz ortho-water line in the interstellar medium of six nearby starburst galaxies. Methods: We used the Odin satellite to observe the 110{-}101 transition of o-H2O in the galaxies NGC 253, IC 342, M 82, NGC 4258, CenA, and M 51. None of the galaxies in our sample was detected. Results: We derive three sigma upper limits to the H2O abundance relative to H2 ranging from 2×10-9 to 1×10-8. The best of these upper limits are comparable to the measured abundance of H2O in the Galactic star forming region W3. However, if only 10% of the molecular gas is in very dense cores, then the water abundance limits in the cores themselves would be larger by a factor of 10 i.e. 2×10-8 to 1×10-7. Conclusions: These observations suggest that detections of H2O emission in galaxies with the upcoming Herschel Space Observatory are likely to require on-source integration times of an hour or more except in the very brightest extragalactic targets such as M 82 and NGC 253.

    The education and careers of naval officers in the long eighteenth century: an international perspective2015In: Journal of Maritime Research, ISSN 1697-4840, E-ISSN 1697-9133, Vol. 17, no 1, p. 17-33Article in journal (Refereed)
    Abstract [en]

    During the long eighteenth century, European navies saw the emergence of a class of highly specialised and professionalised naval officers. These officers were in command of ships and squadrons at major naval battles, led explorations, and in some countries also served ashore as administrators of admiralties and dockyards. Officer training differed from country to country, and careers in different navies were subject to a variety of systems of ranks and promotions that relied both on cultural and on systemic factors. This article explores how the three northern European nations of Sweden, Denmark and Britain developed systems suited to the particular demands of their social and political situations. It presents the results of new research in a comparative context to examine the factors that shaped the development of officer training systems and the criteria used for determining officers' career prospects. Shore-based academies are a useful point of comparison: despite a common curriculum, the development and significance of each navy's academy varied widely. All three navies struggled with the tension between the fundamental demands of life at sea and the behavioural and educational expectations of gentlemen officers. By focusing in particular on officer training, this article provides a variety of perspectives on the origins, emergence, and development of professionalism and expertise in the eighteenth-century maritime world.

    Acrylamide exposure measured by food frequency questionnaire and hemoglobin adduct levels and prostate cancer risk in the Cancer of the Prostate in Sweden Study2009In: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 124, no 10, p. 2384-2390Article in journal (Refereed)
    Abstract [en]

    Acrylamide, a probable human carcinogen, is formed during the cooking of many commonly consumed foods. Data are scant on whether dietary acrylamide represents an important cancer risk in humans. We studied the association between acrylamide and prostate cancer risk using 2 measures of acrylamide exposure: intake from a food frequency questionnaire (FFQ) and acrylamide adducts to hemoglobin. We also studied the correlation between these 2 exposure measures. We used data from the population-based case-control study Cancer of the Prostate in Sweden (CAPS). Dietary data was available for 1,499 cases and 1,118 controls. Hemoglobin adducts of acrylamide were measured in blood samples from a subset of 170 cases and 161 controls. We calculated odds ratios (ORs) for the risk of prostate cancer in high versus low quantiles of acrylamide exposure using logistic regression. The correlation between FFQ acrylamide intake and acrylamide adducts in non-smokers was 0.25 (95% confidence interval: 0.14-0.35), adjusted for age, region, energy intake, and laboratory batch. Among controls the correlation was 0.35 (95% CI: 0.21-0.48); among cases it was 0.15 (95% CI: 0.00-0.30). The OR of prostate cancer for the highest versus lowest quartile of acrylamide adducts was 0.93 (95% CI: 0.47-1.85, p-value for trend = 0.98). For FFQ acrylamide, the OR of prostate cancer for the highest versus lowest quintile was 0.97 (95% CI: 0.75-1.27, p trend = 0.67). No significant associations were found between acrylamide exposure and risk of prostate cancer by stage, grade, or PSA level. Acrylamide adducts to hemoglobin and FFQ-measured acrylamide intake were moderately correlated. Neither measure of acrylamide exposure-hemoglobin adducts or FFQ-was associated with risk of prostate cancer.

    Validation of a food frequency questionnaire measurement of dietary acrylamide intake using hemoglobin adducts of acrylamide and glycidamide2009In: Cancer Causes and Control, ISSN 0957-5243, E-ISSN 1573-7225, Vol. 20, no 3, p. 269-278Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: Acrylamide, a probable human carcinogen, is formed during high-heat cooking of many common foods. The validity of food frequency questionnaire (FFQ) measures of acrylamide intake has not been established. We assessed the validity of acrylamide intake calculated from an FFQ using a biomarker of acrylamide exposure. METHODS: We calculated acrylamide intake from an FFQ in the Nurses' Health Study II. We measured hemoglobin adducts of acrylamide and its metabolite, glycidamide, in a random sample of 342 women. Correlation and regression analyses were used to assess the relationship between acrylamide intakes and adducts. RESULTS: The correlation between acrylamide intake and the sum of acrylamide and glycidamide adducts was 0.31 (95% CI: 0.20-0.41), adjusted for laboratory batch, energy intake, and age. Further adjustment for BMI, alcohol intake, and correction for random within-person measurement error in adducts gave a correlation of 0.34 (CI: 0.23-0.45). The intraclass correlation coefficient for the sum of adducts was 0.77 in blood samples collected 1-3 years apart in a subset of 45 women. Intake of several foods significantly predicted adducts in multiple regression. CONCLUSIONS: Acrylamide intake and hemoglobin adducts of acrylamide and glycidamide were moderately correlated. Within-person consistency in adducts was high over time.

    X-ray absorption spectroscopy of liquid methanol microjets: surface vs. bulk electronic structure and hydrogen bonding2005In: Journal of Physical Chemistry B, ISSN 1520-6106, E-ISSN 1520-5207, Vol. 109, no 20, p. 10194-10203Article in journal (Refereed)
    Abstract [en]

    We have measured the X-ray absorption (XA) spectrum of liquid (298 K) methanol at the oxygen and carbon K edges. The 4a1 orbital at the O K edge exhibits a pronounced sensitivity to the formation of intermolecular hydrogen bonds, with significant differences observed between the vapor and bulk spectra, whereas the C K edge reveals only subtle corresponding spectral changes. Comparison with DFT computed spectra of model methanol clusters indicates that the bulk liquid comprises long chains (n > 6) and rings of hydrogen-bonded monomers.

    Abstract [en]

    The purpose of EuroHCIR is to push the agenda of understanding the role that HCI has with IR systems, beyond Interactive IR. Alongside the popular American HCIR series, EuroHCIR aims to stimulate this focus in the large European community. While the previous two workshops have taken place at more HCI focused conferences (BCS-HCI and IIiX2012), the particular purpose of running EuroHCIR2013 at SIGIR2013 is to better engage with the core IR community, on extended search scenarios like holiday planning, entertainment, and casual browsing.

    Abstract [en]

    EuroHCIR 2013 was organised with the specific goal of better engaging the IR community, who have been underrepresented at previous EuroHCIR conferences. Thus we proposed to have the workshop at the ACM SIGIR conference in Dublin. Research, Industry, and Position papers were invited, and although very few industry submissions were received, we received a number of research and position papers focusing on the intersection of IR and HCI evaluations, several focusing on adapting the TREC paradigm. Many interesting system and demonstrator papers were also accepted.

    Molecular Dynamics Simulation of the Antiamoebin Ion Channel: Linking Structure and Conductance2011In: Biophysical Journal, ISSN 0006-3495, E-ISSN 1542-0086, Vol. 100, no 10, p. 2394-402Article in journal (Refereed)
    Abstract [en]

    Molecular-dynamics simulations were carried out to ascertain which of the potential multimeric forms of the transmembrane peptaibol channel, antiamoebin, is consistent with its measured conductance. Estimates of the conductance obtained through counting ions that cross the channel and by solving the Nernst-Planck equation yield consistent results, indicating that the motion of ions inside the channel can be satisfactorily described as diffusive. The calculated conductance of octameric channels is markedly higher than the conductance measured in single channel recordings, whereas the tetramer appears to be nonconducting. The conductance of the hexamer was estimated to be 115 ± 34 pS and 74 ± 20 pS, at 150 mV and 75 mV, respectively, in satisfactory agreement with the value of 90 pS measured at 75 mV. On this basis, we propose that the antiamoebin channel consists of six monomers. Its pore is large enough to accommodate K+ and Cl with their first solvation shells intact. The free energy barrier encountered by K+ is only 2.2 kcal/mol whereas Cl encounters a substantially higher barrier of nearly 5 kcal/mol. This difference makes the channel selective for cations. Ion crossing events are shown to be uncorrelated and follow Poisson statistics.

    Improved dendroclimatic calibration using blue intensity in the southern Yukon2019In: The Holocene, ISSN 0959-6836, E-ISSN 1477-0911, Vol. 29, no 11, p. 1817-1830Article in journal (Refereed)
    Abstract [en]

    In north-western North America, the so-called divergence problem (DP) is expressed in tree ring width (RW) as an unstable temperature signal in recent decades. Maximum latewood density (MXD), from the same region, shows minimal evidence of DP. While MXD is a superior proxy for summer temperatures, there are very few long MXD records from North America. Latewood blue intensity (LWB) measures similar wood properties as MXD, expresses a similar climate response, is much cheaper to generate and thereby could provide the means to profoundly expand the extant network of temperature sensitive tree-ring (TR) chronologies in North America. In this study, LWB is measured from 17 white spruce sites (Picea glauca) in south-western Yukon to test whether LWB is immune to the temporal calibration instabilities observed in RW. A number of detrending methodologies are examined. The strongest calibration results for both RW and LWB are consistently returned using age-dependent spline (ADS) detrending within the signal-free (SF) framework. RW data calibrate best with June-July maximum temperatures (Tmax), explaining up to 28% variance, but all models fail validation and residual analysis. In comparison, LWB calibrates strongly (explaining 43-51% of May-August Tmax) and validates well. The reconstruction extends to 1337 CE, but uncertainties increase substantially before the early 17th century because of low replication. RW-, MXD- and LWB-based summer temperature reconstructions from the Gulf of Alaska, the Wrangell Mountains and Northern Alaska display good agreement at multi-decadal and higher frequencies, but the Yukon LWB reconstruction appears potentially limited in its expression of centennial-scale variation. While LWB improves dendroclimatic calibration, future work must focus on suitably preserved sub-fossil material to increase replication prior to 1650 CE.

    Reconstructing Holocene climate from tree rings: The potential for a long chronology from the Scottish Highlands2012In: The Holocene, ISSN 0959-6836, E-ISSN 1477-0911, Vol. 22, no 1, p. 3-11Article in journal (Refereed)
    Abstract [en]

    Despite promising research in the 1980s showing the potential of Scots pine (Pinus sylvestris L.) for the reconstruction of past summer temperatures in the Scottish Highlands, little dendroclimatic work has been attempted in this region since. This reflects, in part, the limited number of sparsely distributed remnant natural/ semi-natural pine woodlands in the Scottish Highlands and the lack of old growth forest therein. On average, most of the pine trees dated in this region are around 225 years in age. Here, we present the first results of an ongoing interdisciplinary initiative to develop a long Scottish chronology through the acquisition of modern, historical and subfossil pine material from the native pinewoods, historic structures and lakes of the Scottish Highlands. Radiocarbon dating of 25 subfossil pine timbers recovered from lake sediments identified the presence of preserved material covering the last 8000 years with initial clusters focused on the last two millennia and early-mid Holocene. Although developing a well-replicated 8000 year pine chronology will take many years, this preliminary study indicates that a millennial length pine chronology from the northwest Cairngorm region is a feasible and realistic objective in the near future. The importance of such a record in this climatically important sector of northwest Europe cannot be underestimated.

    Hydrogenation of organic matter as a terminal electron sink sustains high CO2: CH4 production ratios during anaerobic decomposition2017In: Organic Geochemistry, ISSN 0146-6380, E-ISSN 1873-5290, Vol. 112, p. 22-32Article in journal (Refereed)
    Abstract [en]

    Once inorganic electron acceptors are depleted, organic matter in anoxic environments decomposes by hydrolysis, fermentation, and methanogenesis, requiring syntrophic interactions between microorganisms to achieve energetic favorability. In this classic anaerobic food chain, methanogenesis represents the terminal electron accepting (TEA) process, ultimately producing equimolar CO2 and CH4 for each molecule of organic matter degraded. However, CO2:CH4 production in Sphagnum-derived, mineral-poor, cellulosic peat often substantially exceeds this 1:1 ratio, even in the absence of measureable inorganic TEAs. Since the oxidation state of C in both cellulose-derived organic matter and acetate is 0, and CO2 has an oxidation state of +4, if CH4 (oxidation state -4) is not produced in equal ratio, then some other compound(s) must balance CO2 production by receiving 4 electrons. Here we present evidence for ubiquitous hydrogenation of diverse unsaturated compounds that appear to serve as organic TEAs in peat, thereby providing the necessary electron balance to sustain CO2:CH4 > 1. While organic electron acceptors have previously been proposed to drive microbial respiration of organic matter through the reversible reduction of quinone moieties, the hydrogenation mechanism that we propose, by contrast, reduces CAC double bonds in organic matter thereby serving as (1) a terminal electron sink, (2) a mechanism for degrading complex unsaturated organic molecules, (3) a potential mechanism to regenerate electron-accepting quinones, and, in some cases, (4) a means to alleviate the toxicity of unsaturated aromatic acids. This mechanism for CO2 generation without concomitant CH4 production has the potential to regulate the global warming potential of peatlands by elevating CO2:CH4 production ratios.

    Last millennium northern hemisphere summer temperatures from tree rings: Part I2016In: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 134, p. 1-18Article, review/survey (Refereed)
    Abstract [en]

    Large-scale millennial length Northern Hemisphere (NH) temperature reconstructions have been progressively improved over the last 20 years as new datasets have been developed. This paper, and its companion (Part II, Anchukaitis et al. in prep), details the latest tree-ring (TR) based NH land air temperature reconstruction from a temporal and spatial perspective. This work is the first product of a consortium called N-TREND (Northern Hemisphere Tree-Ring Network Development) which brings together dendroclimatologists to identify a collective strategy for improving large-scale summer temperature reconstructions. The new reconstruction, N-TREND2015, utilises 54 records, a significant expansion compared with previous TR studies, and yields an improved reconstruction with stronger statistical calibration metrics. N-TREND2015 is relatively insensitive to the compositing method and spatial weighting used and validation metrics indicate that the new record portrays reasonable coherence with large scale summer temperatures and is robust at all time-scales from 918 to 2004 where at least 3 TR records exist from each major continental mass. N-TREND2015 indicates a longer and warmer medieval period (similar to 900 1170) than portrayed by previous TR NH reconstructions and by the CMIP5 model ensemble, but with better overall agreement between records for the last 600 years. Future dendroclimatic projects should focus on developing new long records from data-sparse regions such as North America and eastern Eurasia as well as ensuring the measurement of parameters related to latewood density to complement ring-width records which can improve local based calibration substantially.

    Facilitating tree-ring dating of historic conifer timbers using Blue Intensity2017In: Journal of Archaeological Science, ISSN 0305-4403, E-ISSN 1095-9238, Vol. 78, p. 99-111Article in journal (Refereed)
    Abstract [en]

    Dendroarchaeology almost exclusively uses ring-width (RW) data for dating historical structures and artefacts. Such data can be used to date tree-ring sequences when regional climate dominates RW variability. However, the signal in RW data can be obscured due to site specific ecological influences (natural and anthropogenic) that impact crossdating success. In this paper, using data from Scotland, we introduce a novel tree-ring parameter (Blue Intensity BI) and explore its utility for facilitating dendrohistorical dating of conifer samples. BI is similar to latewood density as they both reflect the combined hemicellulose, cellulose and lignin content in the latewood cell walls of conifer species and the amount of these compounds is strongly controlled, at least for trees growing in temperature limited locations, by late summer temperatures. BI not only expresses a strong climate signal, but is also less impacted by site specific ecological influences. It can be concurrently produced with RW data from images of finely sanded conifer samples but at a significantly reduced cost compared to traditional latewood density. Our study shows that the probability of successfully crossdating historical samples is greatly increased using BI compared to RW. Furthermore, due to the large spatial extent of the summer temperature signal expressed by such data, a sparse multi -species conifer network of long BI chronologies across Europe could be used to date and loosely provenance imported material.

    Crucial knowledge gaps in current understanding of climate change impacts on coral reef fishes2010In: Journal of Experimental Biology, ISSN 0022-0949, E-ISSN 1477-9145, Vol. 213, no 6, p. 894-900Article in journal (Refereed)
    Abstract [en]

    Expert opinion was canvassed to identify crucial knowledge gaps in current understanding of climate change impacts on coral reef fishes. Scientists that had published three or more papers on the effects of climate and environmental factors on reef fishes were invited to submit five questions that, if addressed, would improve our understanding of climate change effects on coral reef fishes. Thirty-three scientists provided 155 questions, and 32 scientists scored these questions in terms of: (i) identifying a knowledge gap, (ii) achievability, (iii) applicability to a broad spectrum of species and reef habitats, and (iv) priority. Forty-two per cent of the questions related to habitat associations and community dynamics of fish, reflecting the established effects and immediate concern relating to climate-induced coral loss and habitat degradation. However, there were also questions on fish demographics, physiology, behaviour and management, all of which could be potentially affected by climate change. Irrespective of their individual expertise and background, scientists scored questions from different topics similarly, suggesting limited bias and recognition of a need for greater interdisciplinary and collaborative research. Presented here are the 53 highest-scoring unique questions. These questions should act as a guide for future research, providing a basis for better assessment and management of climate change impacts on coral reefs and associated fish communities.

    CONSTRAINTS ON THE PRESENCE OF SiO GAS IN THE DEBRIS DISK OF HD 1725552016In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 826, no 2, article id 165Article in journal (Refereed)
    Abstract [en]

    We have carried out two sets of observations to quantify the properties of SiO gas in the unusual HD 172555 debris disk: (1) a search for the J = 8-7 rotational transition from the vibrational ground state, carried out with the Atacama Pathfinder EXperiment (APEX) submillimeter telescope and heterodyne receiver at 863 mu m. and (2) a search at 8.3 mu m for the P(17) ro-vibrational transition of gas phase SiO, carried out with the Very Large Telescope (VLT)/VISIR with a resolution, lambda/Delta lambda, of 30,000. The APEX measurement resulted in a 3.3 sigma detection of an interstellar feature, but only an upper limit to emission at the radial velocity and line width expected from HD 172555. The VLT/VISIR result was also an upper limit. These were used to provide limits for the abundance of gas phase SiO. for a range of temperatures. The upper limit from our APEX detection, assuming an 8000 K primary star photospheric excitation, falls more than an order of magnitude below the self-shielding stability threshold derived by Johnson et al. (2012). Our results thus favor a solid-state origin for the 8.3 mu m feature seen in the Spitzer IRS spectrum of the circumstellar excess emission. and the production of circumstellar O I and Si I by SiO UV photolysis. The implications of these estimates are explored in the framework of models of the HD 172555 circumstellar disk.

    NORMBRYTANDE PERFORMATIV I BAROCK OCH SAMTID: En komparativ analys av Artemisia Gentileschis Judit halshugger Holofernes och Sigalit Landaus Barbed Hula2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna kandidatuppsats syftar till att genom en komparativ studie av Artemisia Gentileschis Judit halshugger Holofernes och Sigalit Landaus Barbed Hula visa på de alltjämt pågående patriarkala normer som återfinns i samhället och hur tecken på samt brott mot dessa normer går att finna i barocka konstverk såväl som i samtida konst.

     

    Uppsatsen ställer sig frågorna: Vilka uttryck för genus, religion och politik ger de båda verken och hur kan dessa uttryck tolkas? Hur bekräftar alternativt bryter Artemisias och Landaus verk mot etablerade västerländska genusidentiteter samt vilka religiösa och politiska markörer går att finna i verken, både i en historisk och samtida kontext? Vilka genusperformativa likheter respektive olikheter återfinns i de bägge verken?

     

    En semiotisk läsning av de bägge verkens denotativa och konnotativa nivåer med utgångspunkt i performativa aspekter görs. Mieke Bals semiotiska bildanalys och hennes teorier kring hur man kan genomföra en komparativ analys och ändå undvika normskapande bedömningar ligger till grunden för analysen av de bägge konstverken.

     

    Analysen visar att de bägge konstverken utmanar normativa genusdiskurser som befästs av religiöst och kulturellt betingade patriarkala strukturer.

    Den Svenska Spelbranschens Utveckling2004Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    AB Svenska Spel innehar ett monopol på den svenska marknaden för vadhållning på idrott, undantaget trav- och galoppsport där ATG är monopolister. Ny teknik hotar emellertid spelmonopolet eftersom en ny alternativ spelmarknad vuxit fram på Internet. Internetbolagen kan via Internet nå de spelare som annars måste spela hos monopolbolaget. Detta har medfört problem i form av förlorade intäkter för Svenska Spel. Det har diskuterats om det går att genom reglering tvinga bort Internetbolagen, men detta har i Sverige ansetts medföra stora praktiska problem varför ett sådant förbud i dagsläget inte finns. EG-rätten förbjuder idag sådana monopol som är av ekonomiska skäl, men tillåter sådana som uppstått på grund av social hänsyn. Det svenska spelmonopolets bestående vilar således på att svenska staten kan visa att det primärt är av social hänsyn som monopolet finns.

    Abstract [sv]

    Hur företagen redovisar styrs av rekommendationer och principer som i sin tur har sin grund i de olika redovisningsteoretiska ansatser som finns. Modern redovisningsteori med utgångspunkt i mikroekonomi fokuserar på företaget som en ekonomisk enhet som med sin verksamhet på marknaden påverkar ekonomin. Redovisningsteoretiker inom detta område tenderar att argumentera för att så länge som all information redovisas så spelar det mindre roll hur informationen redovisas.

    Skapas aktieägarvärde i statligt ägda företag? : En studie ur ett Economic Value Added perspektiv på Posten, SAS & SJ2002Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie handlar om statligt ägda företag och om de skapar aktieägarvärde ur ett Economic Value Added perspektiv (EVA). EVA är ett integrerat system för finansiell styrning av företag. Utgångspunkten är att varje verksamhets övergripande mål är att skapa mervärde. Ett positivt EVA-värde innebär att värde har skapats för aktieägarna medan ett negativt värde innebär att värde förstörts. Syftet med studien är att tillämpa EVA-modellen som mått för att visa om statligt ägda företag skapar aktieägarvärde. De företag vi valt att undersöka är Posten, SAS och SJ, tre företag som står under Näringsdepartementets förvaltning. Ordet ”värde” kan ha många olika betydelser. I föreliggande studie syftar värde till att beskriva vad någon är beredd att betala för aktier, eller nettotillgångar i ett företag. Den grundläggande principen kan formuleras på följande sätt: Ett företag skapar värde för sina aktieägare endast om det egna kapitalet avkastar mer än vad det kostar. Enkelt uttryckt bygger EVA på att aktieägarna ska få tillräcklig avkastning på investerat kapital, att vinsten av en investering ska överstiga de totala kostnaderna för placeringen, såväl lånat som eget kapital.

    Den upplevda stressens dimensioner; utveckling och prospektiv studie av ett nytt självskattningsinstrument2010Student paper other, 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Befintliga självskattningsinstrument avseende mätning av stress är ofta teoretiska konstruktioner och sällan baserade på empiriska undersökningar av människors faktiska upplevelser. Instrumenten är i allmänhet validerade genom tvärsnittsstudier mot liknande skalor eller tangerande dimensioner som t ex ångest. Syftet med denna studie är att utifrån människors beskrivningar av stressupplevelsen utveckla ett nytt självskattningsinstrument för upplevd stress. Studien är indelad i tre delar. Den första delen är en intervjustudie (16 personer med blandande bakgrunder) där de ord och uttryck som används för att beskriva upplevelsen av stress tematiskt analyseras. Resultatet från denna analys ligger i nästa del till grund för formulerandet av en rad olika påståenden. Förhållandet mellan dessa påståenden analyserades med en explorativ faktor analys (56 universitetsstudenter). I den sista studien valideras dessa påståenden longitudinellt över två olika stressbetingelser (77 universitetsstudenter).

    Beyond Bright City Lights: The Migration Patterns of Gay Men and Lesbians2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    One of the most persistent popular notions of gay men and lesbians is that they either live in or move to larger cities. In this thesis, the geography and migration paths of gay men and lesbians are studied using the life course perspective to challenge this idea. It is argued that gay men and lesbians are affected by the time and place into which they are born. Like heterosexuals, they are subject to the normative conceptions of life paths that are present at a specific historical period and place. Adopting a mixed-methods approach, four studies related to this aim are conducted.

    The first study shows that the tendency for gay men and lesbians to be concentrated to the largest cities in Sweden is greater than for heterosexuals. However, it also shows that the concentration tendency of lesbians and couples is less strong. The second study illustrates that tolerance plays no role in the geographical concentration of gay men and lesbians. Although perceived tolerance is often assumed to matter, this study shows that measured intolerance does not have an effect on the concentration tendency. The third study explores the migration motives of gay men and lesbians living in the city of Malmö, Sweden. It shows that the life stories of older cohorts resembled typical rural-urban flight stories but that the youngest cohort stressed motives similar to the overall population. This is in sharp contrast to the fourth study, which scrutinises migration stories from Izmir, Turkey. Because legal recognition is lacking, following the same life path as heterosexuals is problematic for gay men and lesbians. Because moving out is connected to this path, they remained living at home longer or never moved. Accordingly, the family played a core role in their lives rather than the rural-urban binary.

    Taken together, these four studies show that the geography and migration patterns of gay men and lesbians are more multifaceted than living in or moving to a larger city.

    Boendesegregation i Sverige – en översikt av det aktuella forskningsläget2018Report (Other academic)
    Abstract [sv]

    I denna rapport ges en översikt av det aktuella forskningsläget gällande boendesegregationen i Sverige med avseende på omfattning och utveckling. Studier visar att den etniska boendesegregationen ökade på 1990-talet men att den under 2000-talet varit stabil eller till och med minskat. Vidare diskuteras vilka effekter olika uppväxtmiljöer får för individers livslopps, så kallade grannskapseffekter. Flera studier visar att uppväxt i olika typer av grannskap påverkar individers utbildningsbanor och arbetsmarknadsintegration. Slutligen diskuteras ett antal apsekter som forskningen kan bidra med till den aktuella debatten.

    As people continue to flee repressive regimes, discussions of refugees’ state of liminality have intensified. Refugee camps and detention centres tend to force refugees to endure living in liminality for long periods of time. Taking fleeing as a point of departure, this study suggests a change from the notion of fleeing as movement to a search for home and homemaking. This understanding shifts the analysis away from state-controlled spaces to a wider consideration of spaces of importance for homemaking. Widening the discussion on liminality to homemaking indicates that liminality can be experienced in a variety of spaces. Using material from interviews with queer refugees in the Swedish countryside, I discuss their travels, displacements and homemaking. Their stories show that creating a home is a continuous process delimited by norms in families, ethnic networks, host societies and queer networks. Not adhering to these norms renders homemaking difficult and pushes some queer refugees to liminal spaces. Thus, I suggest an understanding of some queer refugees as constantly rejected and pushed into a perpetual state of liminal homemaking. An analysis that illuminates refugees’ displacements from belonging moves discussions of liminality away from state-controlled spaces and highlights the norms that govern the homemaking process.

    Is It Really Tolerance? Expanding the Knowledge About Diversity for the Creative Class2014In: Tijdschrift voor economische en sociale geografie, ISSN 0040-747X, E-ISSN 1467-9663, Vol. 105, no 1, p. 46-63Article in journal (Refereed)
    Abstract [en]

    Among current theories on regional development the creative capital has received major attention. Several assessments of the theory have shown that tolerance and creativity cannot be ignored. However, as the focus in these assessments mainly has been to replicate the results of Richard Florida, they have put less emphasis on the issues the tolerance measures pose. This paper argues that tolerance has only been measured by diverse population and that this is insufficient. To solve this issue a variety of tolerance measures are introduced and underlying effects of other variables are tested for. Surprisingly, the only measure significant in the model is the bohemian measure. On the one hand, this renders support for the creative capital theory and suggests that attracting bohemian employees can gain economic growth. On the other hand, it problematises the tolerance concept and indicates that tolerance is hard to grasp and add to economic models.

    Metoder och angreppssätt för att fånga in social hållbarhet och nytta2017In: Metoder och verktyg för sociala nyttoberäkningar i kollektivtrafiken / [ed] Thomas Wimark, Stockholm: Kulturgeografiska institutionen, Stockholms Universitet , 2017, p. 1-8Chapter in book (Other academic)
    Abstract [sv]

    I olika kommuner och regioner har det skett ett arbete under det senaste decenniet för att fånga in vad som menas med social hållbarhet/nytta och hur det ska kunna mätas. Det har inte vuxit fram någon konsensus från detta arbete. Det saknas därför kunskap om vilka aspekter av social hållbarhet som är viktiga för kollektivtrafikplaneringen. Vidare saknas information om hur sociala nyttor skall kunna kvantifieras och integreras i olika kalkyler i kollektivtrafiksatsningar. Det är med bakgrund i denna problematik som detta forskningsprojekt skapades. Projektet var utformat som en tredelad förstudie där den första delen syftade till att kartlägga vilka metoder och verktyg som används inom forskningen. Syftet med den andra delen var att utforska en kvantitativ metod för att fånga in social nytta. Den tredje delen var designad för att se till vilka kompletterande effekter kvalitativa angreppssätt kan ge till att ringa in social nytta. I denna inledning beskrivs de huvudsakliga resultaten och därefter diskuteras de i det avslutande delkapitlet.

    Abstract [sv]

    I olika kommuner och regioner har det skett ett arbete under det senaste decenniet för att fånga in vad som menas med social hållbarhet/nytta och hur det ska kunna mätas. Det har inte vuxit fram någon konsensus genom detta arbete. Det saknas fortfarande kunskap om vilka aspekter av social hållbarhet som är viktiga för kollektivtrafikplaneringen. Vidare saknas information om hur sociala nyttor skall kunna kvantifieras och integreras i olika kalkyler i kollektivtrafiksatsningar. Det är med bakgrund i denna problematik som detta forskningsprojekt skapades. Projektet var utformat som en tredelad förstudie där den första delen syftade till att kartlägga vilka metoder och verktyg som används inom forskningen. Syftet med den andra delen var att utforska en kvantitativ metod för att fånga in social nytta. Den tredje delen var designad för att se till vilka kompletterande effekter kvalitativa angreppssätt kan ge till att ringa in social nytta. Vi hoppas att denna bok kan fylla igen den lucka i diskussionerna om social hållbarhet och nytta inom infrastruktursatsningar. Den kan fungera som en utgångpunkt för diskussioner om social hållbarhet och nytta och föranleda en starkare fokusering på social hållbarhet i planeringen av kollektivtrafiken.

    Migration motives of gay men in the new acceptance era: a cohort study from Malmö, Sweden2016In: Social & cultural geography (Print), ISSN 1464-9365, E-ISSN 1470-1197, Vol. 17, no 5, p. 605-622Article in journal (Refereed)
    Abstract [en]

    Greater diversity in life courses has become both possible and real in the twenty-first century, affecting the relocation behaviours of individuals. Therefore, it is logical that the relocation patterns of minorities have been receiving increasing attention. In particular, the migration patterns of gay men have been studied, with a focus on the embodied reasons for mobility. This downsized analysis has shown the importance of identity building and identity search. However, this article argues that analysis of migration among gay men also needs to be upsized. This study aims to show how both context and embodiment has affected the mobility of gay men. Through a case study within the context of a strong welfare state (Sweden) that adopted sexual equality early, gay men’s motives for migration are studied. The results suggest that the migration patterns of gay men are becoming more similar to those of the general population. This finding shows that current conceptualisations of the migration patterns of gay men can be advanced by acknowledging contextual effects. The integration of a downsized and an upsized understanding also offers the possibility of moving beyond the identity specifics showing that populations are becoming increasingly diverse and homogeneous simultaneously.

    Sexuality and Emotions Situated in Time and Space2019In: Affective Dimensions of Fieldwork and Ethnography / [ed] Thomas Stodulka, Samia Dinkelaker, Ferdiansyah Thajib, Cham: Springer, 2019, p. 157-166Chapter in book (Refereed)
    Abstract [en]

    In this chapter, I discuss sexual emotions erupting during fieldwork and argue that sexualities are situated in time and space. In order to understand these emotions, we need to recognize that sexualities are conceptualized in many ways and that different ways of expressing sexuality coexist and are interlinked. Drawing from experiences from three fieldwork periods, I propose a framework for analyzing researcher emotions with an emphasis on individuals without ignoring structure and context. Building on the life course concept, this entails thinking of affect as divided into a “feeling position” and “feeling experience.” Developing a unique feeling position, closest to an understanding of a mental state, it is deeply individual and dependent on the bodies, structures and contexts as individuals go through in life. Feeling positions both enable and disable feeling experiences in the daily lives, i.e., the expressed emotions at any point of time. However, feeling experiences also feed back to the position and ultimately prompt individual change. The fieldwork experiences discussed in this chapter demonstrate how sexuality and race, albeit from a privileged position, are conceived in different ways depending on time and space. Traveling through these times and spaces means being interpellated in ways, perhaps other than learned, and simultaneously adding yet other ways to be understood. These potentially confusing situations can become tangible through the emotions expressed or felt in the field. Applying the proposed life course concept is one way to made sense of these situations.
