    Att drabbas av kronisk sjukdom: En studie om livsomställningen efter hjärtinfarkt2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to highlight the crisis and adjustment process in individuals who suffered myocardial infarction. The research questions focus on the informants’ experiences of the crisis and life adjustment process, and illuminate the coping strategies that the informants describe important. By using a narrative method and applyingthe crisis theory and coping theory as theoretical guidelines, this study endeavors to illuminate individuals' experiences of the disease from their own perspective. The empirical material consists of four life stories gatheredthrough semi-structured interviews. The result indicates general patterns that characterize the course of the diseaseat the same time as individual aspectsof the crisis process are shown, where individual coping strategies have proven necessary through the different phases. The individual aspect on how one cope with crisis seems to depend on personality and life situation. Major life adjustments have proven necessary in the course of the disease. Changes and priorities seem to be revalued through the different phases, along with a greater appreciation for life. Importance of social support is being emphasized; however the most important element appears to be their own, personalefforts and transformation.

    Kampen det varit tyst om: Svenska rösträttskvinnorna kämpade i 20 år2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den svenska kvinnorösträttskampen har osynliggjorts i den nationella historieskrivningen om demokratiseringsprocessen. De engelska suffragetternas kamp är känd, och hur de offrade sina kroppar för rösträtten. Men de svenska rösträttskvinnorna offrade också sina kroppar för rösträtten i en nära 20 år lång kamp med hårt motstånd. Det är en förvånansvärt okänd och oberättad historia - trots att rösträtt för kvinnor är en grundläggande förutsättning för demokrati och medborgarskap. Här berättas storyn om "Landsföreningen för kvinnas politiska rösträtt" och dess ledare Signe Bergman.

    Abstract [sv]

    Börsvärdering har traditionellt sätt inneburit en svår uppgift och erfarenheten visar att föreställningarna om framtiden inte alltid varit så realistiska, vilket tidvis banat väg för finansiella bubblor. Efterfrågan på en enkel värderingsmodell fick Federal Reserve att agera och utveckla ”The Fed-Model”.

    Insynshandel i tillväxtbolag: En studie av Aktietorget och Nordic Growth Market2006Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Tidigare forskning har indikerat att det kan existera informationsasymmetrier i aktiemarknaden mellan olika marknadsaktörer. Personer med insyn har oftast tillgång till särskild information som inte är tillgänglig för marknaden. Detta innebär att möjligheter till abnormala avkastningar existerar för dessa personer vid handel av bolagets finansiella instrument. Denna studie undersöker i första hand huruvida insynshandel på Aktietorget och Nordic Growth Market genererar abnormal avkastning samt om det föreligger en skillnad i resultat mellan dessa marknadsplatser. Det som ligger till grund för studien är insiders samtliga köp- och säljtransaktioner under 2005 för bolag noterade på Aktietorget och Nordic Growth Market. Studien är av kvantitativt slag och använder sig av marknadsmodellen för att beräkna förväntad och abnormal avkastning hos bolagen. Resultaten visar att det råder abnormal avkastning för både Aktietorget och Nordic Growth Market under den testade tidsperioden. Aktietorget visar att eventfönstret har en genomsnittlig abnormal avkastning om 2,93 % för köptransaktioner och 2,33 % för säljtransaktioner medan Nordic Growth Market har en genomsnittlig abnormal avkastning om 4,68 % för köptransaktioner och 2,19 % för säljtransaktioner.

    Future response of temperature and precipitation to reduced aerosol emissions as compared with increased greenhouse gas concentrations2017In: Journal of Climate, ISSN 0894-8755, E-ISSN 1520-0442, Vol. 30, no 3, p. 939-954Article in journal (Refereed)
    Abstract [en]

    Experiments with a climate model (NorESM1) were performed to isolate the effects of aerosol particles and greenhouse gases on surface temperature and precipitation in simulations of future climate. The simulations show that by 2025-2049, a reduction of aerosol emissions from fossil fuels following a maximum technically feasible reduction (MFR) scenario could lead to a global and Arctic warming of 0.26 K and 0.84 K, respectively; as compared with a simulation with fixed aerosol emissions at the level of 2005. If fossil fuel emissions of aerosols follow a current legislation emissions (CLE) scenario, the NorESM1 model simulations yield a non-significant change in global and Arctic average surface temperature as compared with aerosol emissions fixed at year 2005. The corresponding greenhouse gas effect following the RCP4.5 emission scenario leads to a global and Arctic warming of 0.35 K and 0.94 K, respectively.

    The model yields a marked annual average northward shift in the inter-tropical convergence zone with decreasing aerosol emissions and subsequent warming of the northern hemisphere. The shift is most pronounced in the MFR scenario but also visible in the CLE scenario. The modeled temperature response to a change in greenhouse gas concentrations is relatively symmetric between the hemispheres and there is no marked shift in the annual average position of the inter-tropical convergence zone. The strong reduction in aerosol emissions in MFR also leads to a net southward cross-hemispheric energy transport anomaly both in the atmosphere and ocean, and enhanced monsoon circulation in Southeast and East Asia causing an increase in precipitation over a large part of this region.

    Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. Human activities have altered the natural and anthropogenic emissions of aerosol particles through direct emissions or indirectly by modifying natural sources. The climate effects of the latter have been largely overlooked. Humans have dramatically altered the land surface of the planet causing changes in natural aerosol emissions from vegetated areas. Regulation on anthropogenic and natural aerosol emissions have the potential to affect the climate on regional to global scales. Furthermore, the regional climate effects of aerosol particles could potentially be very different than the ones caused by other climate forcers (e.g. well mixed greenhouse gases). The main objective of this work was to investigate the climatic effects of land use and air pollution via aerosol changes.

    Using numerical model simulations it was found that land use changes in the past millennium have likely caused a positive radiative forcing via aerosol climate interactions. The forcing is an order of magnitude smaller and has an opposite sign than the radiative forcing caused by direct aerosol emissions changes from other human activities. The results also indicate that future reductions of fossil fuel aerosols via air quality regulations may lead to an additional warming of the planet by mid-21st century and could also cause an important Arctic amplification of the warming. In addition, the mean position of the intertropical convergence zone and the Asian monsoon appear to be sensitive to aerosol emission reductions from air quality regulations. For these reasons, climate mitigation policies should take into consideration aerosol air pollution, which has not received sufficient attention in the past.

    Historical anthropogenic radiative forcing of changes in biogenic secondary organic aerosol2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Human activities have lead to changes in the energy balance of the Earth and the global climate. Changes in atmospheric aerosols are the second largest contributor to climate change after greenhouse gases since 1750 A.D. Land-use practices and other environmental drivers have caused changes in the emission of biogenic volatile organic compounds (BVOCs) and secondary organic aerosol (SOA) well before 1750 A.D, possibly causing climate effects through aerosol-radiation and aerosol-cloud interactions. Two numerical emission models LPJ-GUESS and MEGAN were used to quantify the changes in aerosol forming BVOC emissions in the past millennium. A chemical transport model of the atmosphere (GEOS-Chem-TOMAS) was driven with those BVOC emissions to quantify the effects on radiation caused by millennial changes in SOA.

    The specific objectives of this licentiate thesis are: 1) to understand what drove the changes in aerosol-forming BVOC emissions (i.e. isoprene, monoterpenes and sesquiterpenes) and to quantify these changes; 2) to calculate for the first time the combined historical aerosol direct and aerosol-cloud albedo effects on radiation from changing BVOC emissions through SOA formation; 3) to investigate how important the biological climate feedback associated to BVOC emissions and SOA formation is from a global climate perspective.

    We find that global isoprene emissions decreased after 1800 A.D. by about 12% - 15%. This decrease was dominated by losses of natural vegetation, whereas monoterpene and sesquiterpene emissions increased by about 2% - 10%, driven mostly by rising surface air temperatures. From 1000 A.D. to 1800 A.D, isoprene, monoterpene and sesquiterpene emissions decline by 3% - 8% driven by both, natural vegetation losses, and the moderate global cooling between the medieval climate anomaly and the little ice age. The millennial reduction in BVOC emissions lead to a 0.5% to 2% reduction in climatically relevant aerosol particles (> 80 nm) and cause a direct radiative forcing between +0.02 W/m² and +0.07 W/m², and an indirect radiative forcing between -0.02 W/m² and +0.02 W/m². The suggested biological climate feedback seems to be too small to have observable consequences on the global climate in the recent past.

    Global emissions of terpenoid VOCs from terrestrial vegetation in the last millennium2014In: Journal of Geophysical Research - Atmospheres, ISSN 2169-897X, E-ISSN 2169-8996, Vol. 119, no 11, p. 6867-6885Article in journal (Refereed)
    Abstract [en]

    We investigated the millennial variability (1000 A.D.-2000 A.D.) of global biogenic volatile organic compound (BVOC) emissions by using two independent numerical models: The Model of Emissions of Gases and Aerosols from Nature (MEGAN), for isoprene, monoterpene, and sesquiterpene, and Lund-Potsdam-Jena-General Ecosystem Simulator (LPJ-GUESS), for isoprene and monoterpenes. We found the millennial trends of global isoprene emissions to be mostly affected by land cover and atmospheric carbon dioxide changes, whereas monoterpene and sesquiterpene emission trends were dominated by temperature change. Isoprene emissions declined substantially in regions with large and rapid land cover change. In addition, isoprene emission sensitivity to drought proved to have significant short-term global effects. By the end of the past millennium MEGAN isoprene emissions were 634 TgC yr-1 (13% and 19% less than during 1750-1850 and 1000-1200, respectively), and LPJ-GUESS emissions were 323 TgC yr-1(15% and 20% less than during 1750-1850 and 1000-1200, respectively). Monoterpene emissions were 89 TgC yr-1(10% and 6% higher than during 1750-1850 and 1000-1200, respectively) in MEGAN, and 24 TgC yr-1 (2% higher and 5% less than during 1750-1850 and 1000-1200, respectively) in LPJ-GUESS. MEGAN sesquiterpene emissions were 36 TgC yr-1(10% and 4% higher than during 1750-1850 and 1000-1200, respectively). Although both models capture similar emission trends, the magnitude of the emissions are different. This highlights the importance of building better constraints on VOC emissions from terrestrial vegetation.

    Amplification of Arctic warming by past air pollution reductions in Europe2016In: Nature Geoscience, ISSN 1752-0894, E-ISSN 1752-0908, Vol. 9, no 4, p. 277-+Article in journal (Refereed)
    Abstract [en]

    The Arctic region is warming considerably faster than the rest of the globe(1), with important consequences for the ecosystems(2) and human exploration of the region(3). However, the reasons behind this Arctic amplification are not entirely clear(4). As a result of measures to enhance air quality, anthropogenic emissions of particulate matter and its precursors have drastically decreased in parts of the Northern Hemisphere over the past three decades(5). Here we present simulations with an Earth system model with comprehensive aerosol physics and chemistry that show that the sulfate aerosol reductions in Europe since 1980 can potentially explain a significant fraction of Arctic warming over that period. Specifically, the Arctic region receives an additional 0.3Wm(-2) of energy, and warms by 0.5 degrees C on annual average in simulations with declining European sulfur emissions in line with historical observations, compared with a model simulation with fixed European emissions at 1980 levels. Arctic warming is amplified mainly in fall and winter, but the warming is initiated in summer by an increase in incoming solar radiation as well as an enhanced poleward oceanic and atmospheric heat transport. The simulated summertime energy surplus reduces sea-ice cover, which leads to a transfer of heat from the Arctic Ocean to the atmosphere. We conclude that air quality regulations in the Northern Hemisphere, the ocean and atmospheric circulation, and Arctic climate are inherently linked.

    MERCOSUR SOM ETT NYTT REGIONALT BLOCK: Ett steg närmare en Sydamerikansk Union?2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen har till syfte att undersöka huruvida MERCOSUR är en aktör på den internationella arenan och om dess tilltagande utveckling kommer kunna bidra till ett ökat interregionalt samarbete. Uppsatsen ska uppnå syftet genom att svara på två frågeställningar: 1) Kan MERCOSUR definieras som en aktör på den internationella arenan? 2) Kan MERCOSUR ses som ett nytt regionalt block och därmed ingå i interregionala samarbeten?

    Uppsatsen går igenom nya regionala blockens uppkomst och vad som skiljer dem åt från andra frihandels avtal. Uppsatsen är en komparativ analys som använder sig av två modeller för att svara på frågeställningarna. Den ena är Björn Hettnes dynamiska modell som beskriver en förändringsprocess. Den andra modellen består av fem kriterier, vilka definierats av Bretherton och Vogler och definierar ett aktörsbeteende. Denna typ av modell är, till skillnad från Hettnes, en statisk modell som används för att definiera grundläggande egenskaper. I samband med Bretherton och Voglers kriterier undersöks fundamentala begrepp, så som actorness och regioness, för att på underlätta analysen om huruvida MERCOSUR agerar som en aktör. För att kunna förstå uppkomsten och utvecklingen av regionala block undersöks hur EU skapades och uppkomsten av Europeiska värderingar samt en introduktion till regionala sammanslutningar i Latinamerika. EU är det äldsta regionala blocket vars gemensamma politik innefattar både ekonomiska och politiska mål. EU stödjer hela den regionala utvecklingen i Latin Amerika och dess interregionala politik bygger på dialog och samförstånd vilket gynnar sammanslutningarna i kontinenten. Speciellt har utvecklingen i MERCOSUR varit av intresse. MERCOSUR har blivit sedd som ett alternativ till det USA drivna projektet FTAA.

    THE CURIOUS CASE OF Ly alpha EMITTERS: GROWING YOUNGER FROM z similar to 3 to z similar to 2?2012In: Astrophysical Journal Letters, ISSN 2041-8205, E-ISSN 2041-8213, Vol. 751, no 2, article id L26Article in journal (Refereed)
    Abstract [en]

    Ly alpha emitting (LAE) galaxies are thought to be progenitors of present-day L* galaxies. Clustering analyses have suggested that LAEs at z similar to 3 might evolve into LAEs at z similar to 2, but it is unclear whether the physical nature of these galaxies is compatible with this hypothesis. Several groups have investigated the properties of LAEs using spectral energy distribution (SED) fitting, but direct comparison of their results is complicated by inconsistencies in the treatment of the data and in the assumptions made in modeling the stellar populations, which are degenerate with the effects of galaxy evolution. By using the same data analysis pipeline and SED fitting software on two stacked samples of LAEs at z = 3.1 and z = 2.1, and by eliminating several systematic uncertainties that might cause a discrepancy, we determine that the physical properties of these two samples of galaxies are dramatically different. LAEs at z = 3.1 are found to be old (age similar to 1 Gyr) and metal-poor (Z < 0.2 Z(circle dot)), while LAEs at z = 2.1 appear to be young (age similar to 50 Myr) and metal-rich (Z > Z(circle dot)). The difference in the observed stellar ages makes it very unlikely that z = 3.1 LAEs evolve directly into z = 2.1 LAEs. Larger samples of galaxies, studies of individual objects, and spectroscopic measurements of metallicity at these redshifts are needed to confirm this picture, which is difficult to reconcile with the effects of 1 Gyr of cosmological evolution.

    Magnetostratigraphic and Cyclostratigraphic Records from Eocene-Miocene Sediments Cored in the Paleoequatorial Pacific: Initial Results from IODP Expedition 3202009Conference paper (Other academic)
    Abstract [en]

    Sediments from the paleoequatorial Pacific record the paleomagnetic field with high-fidelity and contain cyclic variations in chemical and physical properties that can be astronomically tuned, as has been shown from past Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) cruises, e.g., Legs 85, 138, 198, and 199. In an effort to fill gaps from past coring and to construct complete stratigraphic sections spanning the Cenozoic, Integrated Ocean Drilling Program (IODP) Expeditions 320 and 321 cored sediments along a Pacific Equatorial Age Transect (PEAT) earlier this year. A total of 23 holes at 8 Sites (Sites U1331 through U1338) were cored, recovering 6,141 m of sediment (Preliminary Reports are available at http://iodp.tamu.edu/publications/PR.html). Initial paleomagnetic results from Expedition 320 include measurements at 56,222 intervals along ~2000 split-core sections, as well as detailed progressive alternating field (AF) and thermal demagnetization of over 400 discrete samples (7 cm3 cubes). The cleaned paleomagnetic data were characterized by shallow inclinations, consistent with the sites being near the paleoequator, and by 180° alternations in declination downhole, reflecting magnetic polarity zones. The resulting magnetostratigraphies, which are used to develop initial age models for the drill sites, yield 803 dates ranging from 51.743 Ma (the base of Chron 23n.2n at Site 1331) to the present (Chron C1n; 0 to 0.783 Ma at Site U1335). In addition, 83 short polarity intervals were observed that might correspond to cryptochrons or geomagnetic excursions. We will discuss initial efforts to further resolve the PEAT magnetostratigraphies and to integrate them with bio-, chemo-, and cyclo- stratigraphies from the equatorial Pacific and elsewhere in order to improve and extend astronomical calibration of the geologic timescale.

    ICT-based trade facilitation and the MDGs: a case study of a public–private partnership in Ghana2014In: ICTs and the Millennium Development Goals: a United Nations Perspective, Springer, 2014, no 2013, p. 223-235Chapter in book (Other academic)
    Abstract [en]

    The strategic and innovative deployment and use of information and communication technologies (ICT) is important to development and the attainment of the millennium development goals (MDGs). Previous studies have suggested that ICT-based trade facilitation promotes development through better integration into global markets. Through an interpretive case study, this chapter explores an ICTbased initiative to connect members of the trading community in Ghana on an electronic data interchange (EDI) platform. More specifi cally, it explored the contributions of the initiative to effi cient trade facilitation and discusses the broader mplications for achieving the MDGs in Ghana. The research confi rms that the initiative has improved operational effi ciency at Ghana’s ports and borders. Furthermore, it has enabled effi cient and reliable collection of duties and taxes. The findings reinforce the view that government support and private sector expertise and funding are important factors in ICT-based e-government solutions in developing countries. The chapter contends that ICT-based trade facilitation can make a significant contribution to the attainment of the MDGs in Ghana.

    IT Governance Practices in a Public Organization in Ghana2014In: International Journal of Innovation in the Digital Economy, ISSN 1947-8305, E-ISSN 1947-8313, Vol. 5, no 2, p. 14-23Article in journal (Refereed)
    Abstract [en]

    The strategic importance of information technology (IT) in today's organizations and dependence on IT to support e-government strategies has increased the interest in IT Governance (ITG) in public sector organizations. From this perspective, this paper examines ITG practices in a public organization in Ghana (that has a responsibility to mobilize revenue for national development) in order to gain an insight into IT governance structures, processes and relational mechanisms and understand how this contributes to adding value through IT. The findings have revealed that this public organization has a centralized approach to IT governance, with inadequate board involvement concerning how IT investments can bring value and improve organizational performance. Furthermore, there are no IT steering and strategy committees to oversee IT governance as best practice requires.

    Abstract [en]

    In the information age, no organization can thrive without harnessing the power of IT. The effective deployment of IT to achieve business goals and gain competitive advantage requires the alignment of business and IT strategies of organizations. Using the Strategic Alignment Maturity model, this paper evaluates strategic alignment maturity of Customs Excise Preventive service, a frontline public organization charged with trade facilitation in Ghana. Strategic alignment maturity is at level 3; which implies the existence of an established process to leverage IT for efficiency and effectiveness. Efforts are required to strengthen alignment and fully harness the potential of IT to facilitate trade in Ghana.

    N2-fixation, ammonium release and N-transfer to the microbial and classical food web within a plankton community2016In: The ISME Journal, ISSN 1751-7362, E-ISSN 1751-7370, Vol. 10, no 2, p. 450-459Article in journal (Refereed)
    Abstract [en]

    We investigated the role of N2-fixation by the colony-forming cyanobacterium, Aphanizomenon spp., for the plankton community and N-budget of the N-limited Baltic Sea during summer by using stable isotope tracers combined with novel secondary ion mass spectrometry, conventional mass spectrometry and nutrient analysis. When incubated with 15N2Aphanizomenon spp. showed a strong 15N-enrichment implying substantial 15N2-fixation. Intriguingly, Aphanizomenon did not assimilate tracers of 15NH4+ from the surrounding water. These findings are in line with model calculations that confirmed a negligible N-source by diffusion-limited NH4+ fluxes to Aphanizomenon colonies at low bulk concentrations (<250 nm) as compared with N2-fixation within colonies. No N2-fixation was detected in autotrophic microorganisms <5 μm, which relied on NH4+uptake from the surrounding water. Aphanizomenon released about 50% of its newly fixed N2 as NH4+. However, NH4+ did not accumulate in the water but was transferred to heterotrophic and autotrophic microorganisms as well as to diatoms (Chaetoceros sp.) and copepods with a turnover time of ~5 h. We provide direct quantitative evidence that colony-formingAphanizomenon releases about half of its recently fixed N2 as NH4+, which is transferred to the prokaryotic and eukaryotic plankton forming the basis of the food web in the plankton community. Transfer of newly fixed nitrogen to diatoms and copepods furthermore implies a fast export to shallow sediments via fast-sinking fecal pellets and aggregates. Hence, N2-fixing colony-forming cyanobacteria can have profound impact on ecosystem productivity and biogeochemical processes at shorter time scales (hours to days) than previously thought.

    Early Resistance of Non-virulent Mycobacterial Infection in C57BL/6 Mice Is Associated With Rapid Up-Regulation of Antimicrobial Cathelicidin Camp2018In: Frontiers in Immunology, ISSN 1664-3224, E-ISSN 1664-3224, Vol. 9, article id 1939Article in journal (Refereed)
    Abstract [en]

    Early clearance of tuberculosis is the successful eradication of inhaled bacteria before the development of an adaptive immune response. We previously showed, by utilizing a non-virulent mycobacteria infection model, that C57BL/6 mice are more efficient than BALB/c in their control of bacterial growth in the lungs during the first weeks of the infection. Here, we assessed early (within 1-3 days) innate immune events locally in the lungs to identify factors that may contribute to the control of non-virulent mycobacterial burden. We confirmed that C57BL/6 mice are more resistant to infection compared with BALB/c after intranasal inoculation with mycobacterium. Transcriptomic analyses revealed a remarkably silent signature in C57BL/6 mice despite effective control of bacterial growth. In contrast, BALB/c mice up-regulated genes associated with neutrophil and myeloid cell chemotaxis and migration. Flow cytometry analyses corroborated the transcriptomic analyses and demonstrated influx of both neutrophil and myeloid cell populations in BALB/c mice, while these did not increase in C57BL/6 mice. We further detected increased release of TNF-alpha from BALB/c lung cells but limited release from C57BL/6-derived cells. However, C57BL/6 mice showed a marked early up-regulation of the Camp gene, encoding the cathelicidin CRAMP peptide, post-mycobacterial exposure. CRAMP (LL-37 in human) expression in the lungs was confirmed using immunofluorescence staining. Altogether, these findings show that C57BL/6 mice can clear the mycobacterial infection early and that this early control is associated with high CRAMP expression in the lungs without concomitant influx of immune cells. The role of CRAMP/LL-37 during mycobacterial infection may be relevant for novel protective strategies, and warrants further studies of human cohorts.

    Uppsatsen syftar till att undersöka hur den demokratiska planeringsmodellen hanterar frågor gällande medborgerligt deltagande. Vem har makten att påverka och förändra de politiska beslut som planeringsmodellen vilar på? Uppsatsen undersöker utifrån denna övergripande fråga i fallstudieform planeringsprocessen för ett ambitiöst och kontroversiellt framtida bostadsområde i Upplands Väsby kallat Väsby Sjöstad. Den teoretiska ansatsen utgörs av maktbegreppet och dess kopplingar till rationalitet, starkt inspirerat av Michel Foucaults och Bent Flyvbjergs maktteorier. Den huvudsakliga metoden för undersökningen är en diskursanalys. Planeringsprocessen i fallet har genomgått distinkt olika faser och utmynnat i en charrette-inspirerad metod kallad community planning. Metoden medför att en konfliktfylld och låst planeringsprocess omvandlats till en inklusiv och kommunikativ sådan. Slutsatsen är att community planning med fördel kan användas för att ge medborgare en reell makt att påverka politiska beslut och planeringsresultat, men främst under tidiga planskeden.

    Planck 2015 results X. Diffuse component separation: Foreground maps2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 594, article id A10Article in journal (Refereed)
    Abstract [en]

    Planck has mapped the microwave sky in temperature over nine frequency bands between 30 and 857 GHz and in polarization over seven frequency bands between 30 and 353 GHz in polarization. In this paper we consider the problem of diffuse astrophysical component separation, and process these maps within a Bayesian framework to derive an internally consistent set of full-sky astrophysical component maps. Component separation dedicated to cosmic microwave background (CMB) reconstruction is described in a companion paper. For the temperature analysis, we combine the Planck observations with the 9-yr Wilkinson Microwave Anisotropy Probe (WMAP) sky maps and the Haslam et al. 408 MHz map, to derive a joint model of CMB, synchrotron, free-free, spinning dust, CO, line emission in the 94 and 100 GHz channels, and thermal dust emission. Full-sky maps are provided for each component, with an angular resolution varying between 7: 5 and 1 degrees. Global parameters (monopoles, dipoles, relative calibration, and bandpass errors) are fitted jointly with the sky model, and best-fit values are tabulated. For polarization, the model includes CMB, synchrotron, and thermal dust emission. These models provide excellent fits to the observed data, with rms temperature residuals smaller than 4pK over 93% of the sky for all Planck frequencies up to 353 GHz, and fractional errors smaller than 1% in the remaining 7% of the sky. The main limitations of the temperature model at the lower frequencies are internal degeneracies among the spinning dust, free-free, and synchrotron components; additional observations from external low-frequency experiments will be essential to break these degeneracies. The main limitations of the temperature model at the higher frequencies are uncertainties in the 545 and 857 GHz calibration and zero-points. For polarization, the main outstanding issues are instrumental systematics in the 100-353 GHz bands on large angular scales in the form of temperature-to-polarization leakage, uncertainties in the analogue-to-digital conversion, and corrections for the very long time constant of the bolometer detectors, all of which are expected to improve in the near future.

    Abstract [en]

    We present foreground-reduced cosmic microwave background (CMB) maps derived from the full Planck data set in both temperature and polarization. Compared to the corresponding Planck 2013 temperature sky maps, the total data volume is larger by a factor of 3.2 for frequencies between 30 and 70 GHz, and by 1.9 for frequencies between 100 and 857 GHz. In addition, systematic errors in the forms of temperature-topolarization leakage, analogue-to-digital conversion uncertainties, and very long time constant errors have been dramatically reduced, to the extent that the cosmological polarization signal may now be robustly recovered on angular scales l greater than or similar to 40. On the very largest scales, instrumental systematic residuals are still non-negligible compared to the expected cosmological signal, and modes with l < 20 are accordingly suppressed in the current polarization maps by high-pass filtering. As in 2013, four different CMB component separation algorithms are applied to these observations, providing a measure of stability with respect to algorithmic and modelling choices. The resulting polarization maps have rms instrumental noise ranging between 0.21 and 0.27 mu K averaged over 55' pixels, and between 4.5 and 6.1 mu K averaged over 3.'4 pixels. The cosmological parameters derived from the analysis of temperature power spectra are in agreement at the 1 sigma level with the Planck 2015 likelihood. Unresolved mismatches between the noise properties of the data and simulations prevent a satisfactory description of the higher-order statistical properties of the polarization maps. Thus, the primary applications of these polarization maps are those that do not require massive simulations for accurate estimation of uncertainties, for instance estimation of cross-spectra and cross-correlations, or stacking analyses. However, the amplitude of primordial non-Gaussianity is consistent with zero within 2 sigma for all local, equilateral, and orthogonal configurations of the bispectrum, including for polarization E-modes. Moreover, excellent agreement is found regarding the lensing B-mode power spectrum, both internally among the various component separation codes and with the best-fit Planck 2015 Lambda cold dark matter model.

    Planck intermediate results XLIII. Spectral energy distribution of dust in clusters of galaxies2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 596, article id A104Article in journal (Refereed)
    Abstract [en]

    Although infrared (IR) overall dust emission from clusters of galaxies has been statistically detected using data from the Infrared Astronomical Satellite (IRAS), it has not been possible to sample the spectral energy distribution (SED) of this emission over its peak, and thus to break the degeneracy between dust temperature and mass. By complementing the IRAS spectral coverage with Planck satellite data from 100 to 857 GHz, we provide new constraints on the IR spectrum of thermal dust emission in clusters of galaxies. We achieve this by using a stacking approach for a sample of several hundred objects from the Planck cluster sample. This procedure averages out fluctuations from the IR sky, allowing us to reach a significant detection of the faint cluster contribution. We also use the large frequency range probed by Planck, together with component-separation techniques, to remove the contamination from both cosmic microwave background anisotropies and the thermal Sunyaev-Zeldovich effect (tSZ) signal, which dominate at v <= 353 GHz. By excluding dominant spurious signals or systematic effects, averaged detections are reported at frequencies 353 GHz <= v <= 5000 GHz. We confirm the presence of dust in clusters of galaxies at low and intermediate redshifts, yielding an SED with a shape similar to that of the Milky Way. Planck's resolution does not allow us to investigate the detailed spatial distribution of this emission (e.g. whether it comes from intergalactic dust or simply the dust content of the cluster galaxies), but the radial distribution of the emission appears to follow that of the stacked SZ signal, and thus the extent of the clusters. The recovered SED allows us to constrain the dust mass responsible for the signal and its temperature.

    Planck intermediate results XLII. Large-scale Galactic magnetic fields2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 596, article id A103Article in journal (Refereed)
    Abstract [en]

    Recent models for the large-scale Galactic magnetic fields in the literature have been largely constrained by synchrotron emission and Faraday rotation measures. We use three different but representative models to compare their predicted polarized synchrotron and dust emission with that measured by the Planck satellite. We first update these models to match the Planck synchrotron products using a common model for the cosmic-ray leptons. We discuss the impact on this analysis of the ongoing problems of component separation in the Planck microwave bands and of the uncertain cosmic-ray spectrum. In particular, the inferred degree of ordering in the magnetic fields is sensitive to these systematic uncertainties, and we further show the importance of considering the expected variations in the observables in addition to their mean morphology. We then compare the resulting simulated emission to the observed dust polarization and find that the dust predictions do not match the morphology in the Planck data but underpredict the dust polarization away from the plane. We modify one of the models to roughly match both observables at high latitudes by increasing the field ordering in the thin disc near the observer. Though this specific analysis is dependent on the component separation issues, we present the improved model as a proof of concept for how these studies can be advanced in future using complementary information from ongoing and planned observational projects.

    Planck intermediate results XLVII. Planck constraints on reionization history2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 596, article id A108Article in journal (Refereed)
    Abstract [en]

    We investigate constraints on cosmic reionization extracted from the Planck cosmic microwave background (CMB) data. We combine the Planck CMB anisotropy data in temperature with the low-multipole polarization data to fit Lambda CDM models with various parameterizations of the reionization history. We obtain a Thomson optical depth tau = 0.058 +/- 0.012 for the commonly adopted instantaneous reionization model. This confirms, with data solely from CMB anisotropies, the low value suggested by combining Planck 2015 results with other data sets, and also reduces the uncertainties. We reconstruct the history of the ionization fraction using either a symmetric or an asymmetric model for the transition between the neutral and ionized phases. To determine better constraints on the duration of the reionization process, we also make use of measurements of the amplitude of the kinetic Sunyaev-Zeldovich (kSZ) effect using additional information from the high-resolution Atacama Cosmology Telescope and South Pole Telescope experiments. The average redshift at which reionization occurs is found to lie between z = 7.8 and 8.8, depending on the model of reionization adopted. Using kSZ constraints and a redshift-symmetric reionization model, we find an upper limit to the width of the reionization period of Delta z < 2.8. In all cases, we find that the Universe is ionized at less than the 10% level at redshifts above z similar or equal to 10. This suggests that an early onset of reionization is strongly disfavoured by the Planck data. We show that this result also reduces the tension between CMB-based analyses and constraints from other astrophysical sources.

    Abstract [en]

    The European Space Agency's Planck satellite, which is dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 October 2013. In February 2015, ESA and the Planck Collaboration released the second set of cosmology products based on data from the entire Planck mission, including both temperature and polarization, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the main characteristics of the data and the data products in the release, as well as the associated cosmological and astrophysical science results and papers. The data products include maps of the cosmic microwave background (CMB), the thermal Sunyaev-Zeldovich effect, diffuse foregrounds in temperature and polarization, catalogues of compact Galactic and extragalactic sources (including separate catalogues of Sunyaev-Zeldovich clusters and Galactic cold clumps), and extensive simulations of signals and noise used in assessing uncertainties and the performance of the analysis methods. The likelihood code used to assess cosmological models against the Planck data is described, along with a CMB lensing likelihood. Scientific results include cosmological parameters derived from CMB power spectra, gravitational lensing, and cluster counts, as well as constraints on inflation, non-Gaussianity, primordial magnetic fields, dark energy, and modified gravity, and new results on low-frequency Galactic foregrounds.

    Governing from Above: Solid Waste Management in Nigeria's New Capital City of Abuja2007Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This doctoral dissertation examines how the symbolic character of a relocated capital city influences and intersects with local conditions to shape the governance structure and relations in service delivery. The focus is on Abuja, the new capital city of Nigeria, and the sector studied is solid waste management. Abuja was planned to avoid the numerous problems facing other Nigerian cities. Contrary to the intention of government and planners, the city now houses the fastest growing slum in the country. There are various possible explanations for these outcomes but this study pays particular attention to the conception of Abuja as a symbol of national unity.

    The ‘good governance’ agenda is often promoted by the World Bank and donors as a way of handling the numerous challenges facing African governments, including service delivery. A major expectation of the agenda is that local governments manage the urban development process in conjunction with an array of institutions ranging from the private sector to community groups and households. An underlying notion is that of a minimalist national state. This is not the case in Abuja, where governance is conducted at higher levels and the municipal council remains largely invisible. This is manifested in solid waste management, where the municipal council has no jurisdiction over the sector. In addition, community groups and households play very minimal roles in the governance of services. Drawing on the concept of space and place, the study concludes that the types of institutions found and their roles and relations are shaped by the national function of the city and the local power relations.

    The study draws on primary and secondary data. Interviews were conducted with state officials, community leaders, households and interest groups, such as the private sector. Secondary data were obtained from government documents, studies and newspaper reports.

    Urban imaginaries: funding mega infrastructure projects in Lagos, Nigeria2018In: GeoJournal, ISSN 0343-2521, E-ISSN 1572-9893, Vol. 83, no 2, p. 257-274Article in journal (Refereed)
    Abstract [en]

    In today’s globalized world, mega infrastructure projects have emerged as one of the most popular strategies for attracting private capital and repositioning cities on the competitive landscape. The Lagos Megacity Project (LMCP) was launched to address a longstanding infrastructure crisis and to reinvent Lagos as a modern megacity. Using the LMCP as a case study, the paper examined the challenges facing the funding of mega infrastructure projects. Special attention is given to how capital is mobilized, the kinds of alliances or networks found and what gets prioritized. The paper observed that the alliance formed between the federal, Lagos and Ogun state governments to mobilize public funds quickly unraveled largely due to disputes traceable to the apportioning of fiscal and political responsibilities and the distribution of functions between the different tiers of government. Under the LMCP, disputes emerged between the federal government and the Lagos State Government (LSG) over who was responsible for what. A history of opposition politics and a highly politicized resource allocation system further made cooperation between the two particularly difficult. Furthermore, the LMCP signalled a renewed drive by the LSG to attract private investments through public–private partnership. The paper noted a host of problems but crucially there is a preference for elite projects, a practice that is reinforcing socio-spatial exclusion and confirms the persistent inequalities that accompany neoliberal and modernist projects. At the broadest level, the paper points to how modernist projects are fractured or undermined by specific ideologies and practices.

    Dealing with Waste: Resource Recovery and Entrepreneurship in Informal Solid Waste Management in African Cities2017Collection (editor) (Other academic)
    Abstract [en]

    The scope of the problem of waste management in African cities continues to change across space and time in line with changing socio-economic, political and environmental conditions. Crucially, the failure of the formal systems has paved the way for the informal sector. The overall aim of the book is to capture the dynamism and complexity of Informal Sector Solid Waste Management (ISSWM). The main argument is that while the poverty reduction potential of ISSWM remains valid and is acknowledged; there are broader issues to consider.

    Plant roots increase both decomposition and stable organic matter formation in boreal forest soil2019In: Nature Communications, ISSN 2041-1723, E-ISSN 2041-1723, Vol. 10, article id 3982Article in journal (Refereed)
    Abstract [en]

    Boreal forests are ecosystems with low nitrogen (N) availability that store globally significant amounts of carbon (C), mainly in plant biomass and soil organic matter (SOM). Although crucial for future climate change predictions, the mechanisms controlling boreal C and N pools are not well understood. Here, using a three-year field experiment, we compare SOM decomposition and stabilization in the presence of roots, with exclusion of roots but presence of fungal hyphae and with exclusion of both roots and fungal hyphae. Roots accelerate SOM decomposition compared to the root exclusion treatments, but also promote a different soil N economy with higher concentrations of organic soil N compared to inorganic soil N accompanied with the build-up of stable SOM-N. In contrast, root exclusion leads to an inorganic soil N economy (i.e., high level of inorganic N) with reduced stable SOM-N buildup. Based on our findings, we provide a framework on how plant roots affect SOM decomposition and stabilization.

    A Narratable Self as Addressed by Human Rights2017In: Policy Futures in Education, ISSN 1478-2103, E-ISSN 1478-2103, Vol. 15, no 3, p. 252-261Article in journal (Refereed)
    Abstract [en]

    The paper extends the critique in earlier research of human rights as exclusive of otherness and difference by introducing the work of Adriana Cavarero (2000) on a narratable self. Hence, the formation of human rights is thus about the relations between different narratable selves, not just Western ones. A narrative learning, drawing on Cavarero (2000), shifts the focus in human rights learning from learning about the other to exposing one’s life story narrative through relationality.

    Claiming and Reaffirming Universality of Human Rights: Comparing the Role of UNESCO in Relation to the UN 1948 and 19932009Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The thesis explores the role of United Nations Educational, Scientific and Cultural Organization (UNESCO) in the drafting and formulation of the universal human rights in 1948 as well as its contribution at the Vienna Conference, when the universality of the human rights was reaffirmed after the Cold War. Using concept analysis on the reports published by UNESCO for the drafting of the Universal Declaration on Human Rights and the Vienna Declaration deepens the understanding of the influence of the organization within the United Nations (UN) system at these points in time. By applying an intersectional approach to the concept of “cultural dialogue”, the theoretical tool of “intersectional dialogue” is created in order to analyze and understand the process that occurred in the UN Commission when delegates from all over the world met to draft and discuss the universality of human rights. The conceptual framework of “universality” by Langlois is used in analyzing the parallel process of UNESCO in order to understand the universality of the human rights through local interpretations and particular values. The thesis held by Langlois, that the universality of human rights enables a global platform for oppressed and marginalized people to share their local stories based on particular values within a human rights discourse, is contested in the analysis.

    Human rights for more than one voice: rethinking political space beyond the global/local divide2014In: Ethics & Global Politics, ISSN 1654-4951, E-ISSN 1654-6369, Vol. 7, no 4, p. 163-180Article in journal (Refereed)
    Abstract [en]

    This paper considers political agency and space as found in Cavarero's For More Than One Voice: Toward a Philosophy of Vocal Expression in order to take a critical philosophical approach to human rights education (HRE) and the political implications of its increasingly legal discourse. Like Arendt, Cavarero is concerned with a radical rethinking of political space, as not limited to place or legal borders, but bound by our human condition of plurality and relationality. Both Arendt and Cavarero want politics to be coupled with justice, nevertheless, Cavarero provides a notion of politics that lets us think beyond territorial terms of a polis, which opens for exploring an expanded conceptualization of human rights politics, as not bound by national legislative measures, but as concerning political action in-between human beings. In contrast to the dominant discourse on ‘human rights experts’ who frame the content for HRE, the notion of ‘absolute local space’ questions the dichotomy of universal/particular in raising the importance of a plurality of unique voices who create a spectrum for the universality of rights.

    Human Rights Learning: The Significance of Narratives, Relationality and Uniqueness2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Whereas educational policy is mainly concerned with the content of Human Rights Education (HRE), philosophers of education have widely explored the subject and her social condition in terms of social justice education. This thesis draws on philosophers of education in exploring the subject rather than the content of HRE, focusing the study on ontological rather than epistemological aspects of learning. In this thesis learning is explored through narratives, as a relational process of becoming. The turn to narrative is taken against the dominant historical narrative of human rights as a Western project. This turn concerns how claims toward universalism of human rights exclude difference and equally concerns how notions of particularity overshadows the uniqueness in life stories. The concept of uniqueness serves to elucidate the complexity of the subject, not easily reduced into social categorizations, a concept drawn from Adriana Cavarero and Hannah Arendt.

    In a Man's words - the politics of female representation in the public2017In: Studier i Pædagogisk Filosofi, ISSN 2244-9140, E-ISSN 2244-9140, Vol. 6, no 1, p. 55-68Article in journal (Refereed)
    Abstract [en]

    What one decides fi t for appearance through writing and speech bears a political signifi cance that risk being distorted through both language, reception in the public, and through calls for gendered representations. How can work of female philosophers be interpreted as a concern for the world from that of having to respond to a male-dominated discourse through which speech becomes trapped into what one might represent as ‘other’? In this paper, I explore the public reception of two female thinkers who question, in diff erent ways, the domi-nant notion of the author or philosopher as a male subject; what kind of limitations does the relative notion of ‘female’ pose political action, and how can privilege constitute a hindrance to feminist solidarity?

    Intersectional Dialogue - A Cosmopolitical Dialogue of Ethics2013In: Cosmopolitan Civil Societies: An Interdisciplinary Journal, ISSN 1837-5391, E-ISSN 1837-5391, Vol. 5, no 2, p. 45-62Article in journal (Refereed)
    Abstract [en]

    The article is based on a critical cosmopolitan outlook on dialogue as not aimed at reaching consensus, but rather keeping dialogue of difference open, with the ability to reach common understanding of human rights on conflicting grounds. Intersectional dialogue is used as a concept that opens up possibilities to study, in a pragmatic sense, the ‘cosmopolitan space’ in which different axles of power met in the historical drafting of human rights. By enacting analysis of United Nations (UN) documents from 1948 on the process of drafting the Universal Declaration on Human Rights (UDHR) the conceptualization of intersectional dialogue is put to work. The utopian foundation for deliberative democracy as dialogue in the absence of power and interest does not acknowledge the reality in which the human rights were negotiated and debated. The paper questions the dominant narrative of a western philosophical ground for the universality of human rights.

    Morality without Rights? The Empty Space in Cosmopolitan Education2019In: Knowledge Cultures, ISSN 2327-5731, E-ISSN 2375-6527, Vol. 7, no 3, p. 75-86Article in journal (Refereed)
    Abstract [en]

    By problematizing how morality is discussed in cosmopolitan education without addressing the rightlessness of non-citizens I draw on thoughts by Martha Nussbaum and Marianna Papastephanou on how human rights and agency can be reclaimed through a critical cosmopolitanism. Educational philosophy on cosmopolitan education presupposes the juridical right to education. Due to this presupposition, the subject who is excluded by legal limitations of rights is not necessarily addressed by morally conceptualizations of cosmopolitanism and education. This paper seeks to investigate this gap by asking what significance cosmopolitanism and philosophy have for the rightlessness, drawing on the problematization by Hannah Arendt on the limitations of the human rights project. The concept of phronesis is invoked in order to stress the importance for cosmopolitan educationalists to theorize the non-citizen and to address those who are excluded from the legal right to education.

    Reconciling Universality and Particularity through a Cosmopolitan Outlook on Human Rights2012In: Cosmopolitan Civil Societies: An Interdisciplinary Journal, ISSN 1837-5391, E-ISSN 1837-5391, Vol. 4, no 2, p. 22-37Article in journal (Refereed)
    Abstract [en]

    Human rights are today criticized as not compatible with different cultural values and the debate has circulated around Asian values and Islamic values as in dichotomy with human rights as universal ethics (Ignatieff, 2003). The theoretical dichotomy between universality and particularity is questioned pragmatically in this paper through a historical study. The working process of drafting the Universal Declaration of Human Rights (UDHR) in 1946-48, which included thousands of people, is explored as a cosmopolitan space in which individuals from different cultural contexts met to negotiate human rights through cultural narratives. The process where particular values were negotiated with universal notion on human rights resulted in a common proclamation (UDHR) without a common philosophical or ideological ground. This paper puts forth a thesis that human rights discourse can work as a cosmopolitan space, in which particular value systems meet in processes characterized by conflict and cohesion. Hence human rights can be understood as a master narrative compatible with different conflicting cultural narratives (Gibson & Somers, 1994).

    Re-Thinking Relations in Human Rights Learning: The Politics of Narratives2014In: Journal of Philosophy of Education, ISSN 0309-8249, E-ISSN 1467-9752, Vol. 48, no 2, p. 293-307Article in journal (Refereed)
    Abstract [en]

    Human Rights Education (HRE) has traditionally been articulated in terms of cultivating better citizens or world citizens. The main preoccupation in this strand of HRE has been that of bridging a gap between universal notions of a human rights subject and the actual locality and particular narratives in which students are enmeshed. This preoccupation has focused on ‘learning about the other’ in order to improve relations between plural ‘others’ and ‘us’ and reflects educational aims of national identity politics in citizenship education. The article explores the learning of human rights through narratives in relations, drawing on Hannah Arendt and Sharon Todd. For this re-thinking of relations in learning human rights, the article argues that HRE needs to address both competing historical narratives on the drafting of the Universal Declaration on Human Rights (UDHR) as well as unique life narratives of learners.

    The praxis of ethics and justice in human rights learning: examining the limits of progressive education2017In: Ethics and Education, ISSN 1744-9642, E-ISSN 1744-9650, Vol. 2, no 1, p. 37-47Article in journal (Refereed)
    Abstract [en]

    School and education can be seen as an extension of the home as Hannah Arendt stresses, where children are protected in a space in which they can learn and grow, a space that is not yet public. This distinction of education as “not yet public” can be seen in contrast to John Dewey who explores notions of democracy as a process in education, where education and school is regarded as a mini society. This paper explores several challenges with progressive education and, specifically, of human rights education, through the work of Arendt (1959) and Dewey (1990) on the notions of responsibility and children’s human rights. Where do we as educators draw the distinction between taking responsibility of raising awareness of global injustices and human rights violations with the next generation without falling pray to dissolution that the gap between political imaginary and reality faces us with, or risking violating children’s “safe space” in school that according to Arendt should be a space that is neither private nor public, but a free zone for thinking and learning with others? Do we bring into the classroom discrimination and segregation by drawing on social categorizations with the pretext of questioning the same on the basis of “equal rights”? If ethical and relational dimensions of education are to be taken seriously then human rights education is a risky practice since it involves children’s sense of being and it raises questions that may not be dealt with properly or solvable for the children exposed.

    Toward Cosmopolitan Ethics in Teacher Education: An Ontological Dimension of Learning Human Rights2014In: Ethics and Education, ISSN 1744-9642, E-ISSN 1744-9650, Vol. 9, no 1, p. 29-38Article in journal (Refereed)
    Abstract [en]

    There is a globalization trend in teacher education, emphasizing the role of teachers to make judgments based on human rights in their teaching profession. Rather than emphasizing the epistemological dimension of acquiring knowledge about human rights through teacher education, an ontological dimension is emphasized in this paper of what it means to become a professional teacher. An ontological dimension of ‘learning to become’ can be captured in critical examination of a cosmopolitan awareness of teachers in relation to judgment and justice. I read the critique through studies on human rights in teacher education, which transforms notions of openness and respect in relations marked by difference.

    Abstract [en]

    Who were the non-Western women delegates who took part in the drafting of the United Nations Charter and the Universal Declaration of Human Rights (UDHR) from 1945-1948? Which member states did these women represent, and in what ways did they push for a more inclusive language than "the rights of Man" in the texts? This book provides a gendered historical narrative of human rights from the San Francisco Conference in 1945 to the final vote of the UDHR in the United Nations General Assembly in December 1948. It highlights the contributions by Latin American feminist delegates, and the prominent non-Western female representatives from new member states of the UN.
