    XXI. The integrated Sachs-Wolfe effect2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 594, article id A21Article in journal (Refereed)
    Abstract [en]

    This paper presents a study of the integrated Sachs-Wolfe (ISW) effect from the Planck 2015 temperature and polarization data release. This secondary cosmic microwave background (CMB) anisotropy caused by the large-scale time-evolving gravitational potential is probed from different perspectives. The CMB is cross-correlated with different large-scale structure (LSS) tracers: radio sources from the NVSS catalogue; galaxies from the optical SDSS and the infrared WISE surveys; and the Planck 2015 convergence lensing map. The joint cross-correlation of the CMB with the tracers yields a detection at 4 sigma where most of the signal-to-noise is due to the Planck lensing and the NVSS radio catalogue. In fact, the ISW effect is detected from the Planck data only at approximate to 3 sigma (through the ISW-lensing bispectrum), which is similar to the detection level achieved by combining the cross-correlation signal coming from all the galaxy catalogues mentioned above. We study the ability of the ISW effect to place constraints on the dark-energy parameters; in particular, we show that Omega(Lambda) is detected at more than 3 sigma. This cross-correlation analysis is performed only with the Planck temperature data, since the polarization scales available in the 2015 release do not permit significant improvement of the CMB-LSS cross-correlation detectability. Nevertheless, the Planck polarization data are used to study the anomalously large ISW signal previously reported through the aperture photometry on stacked CMB features at the locations of known superclusters and supervoids, which is in conflict with Lambda CDM expectations. We find that the current Planck polarization data do not exclude that this signal could be caused by the ISW effect. In addition, the stacking of the Planck lensing map on the locations of superstructures exhibits a positive cross-correlation with these large-scale structures. Finally, we have improved our previous reconstruction of the ISW temperature fluctuations by combining the information encoded in all the previously mentioned LSS tracers. In particular, we construct a map of the ISW secondary anisotropies and the corresponding uncertainties map, obtained from simulations. We also explore the reconstruction of the ISW anisotropies caused by the large-scale structure traced by the 2MASS Photometric Redshift Survey (2MPZ) by directly inverting the density field into the gravitational potential field.

    Abstract [en]

    Maps of cosmic microwave background (CMB) temperature and polarization from the 2015 release of Planck data provide the highest quality full-sky view of the surface of last scattering available to date. This enables us to detect possible departures from a globally isotropic cosmology. We present the first searches using CMB polarization for correlations induced by a possible non-trivial topology with a fundamental domain that intersects, or nearly intersects, the last-scattering surface (at comoving distance chi(rec)), both via a direct scan for matched circular patterns at the intersections and by an optimal likelihood calculation for specific topologies. We specialize to flat spaces with cubic toroidal (T3) and slab (T1) topologies, finding that explicit searches for the latter are sensitive to other topologies with antipodal symmetry. These searches yield no detection of a compact topology with a scale below the diameter of the last-scattering surface. The limits on the radius R-i of the largest sphere inscribed in the fundamental domain (at log-likelihood ratio Delta ln L > -5 relative to a simply-connected flat Planck best-fit model) are: R-i > 0.97 chi(rec) for the T3 cubic torus; and R-i > 0.56 chi(rec) for the T1 slab. The limit for the T3 cubic torus from the matched-circles search is numerically equivalent, R-i > 0.97 chi(rec) at 99% confidence level from polarization data alone. We also perform a Bayesian search for an anisotropic global Bianchi VIIh geometry. In the non-physical setting, where the Bianchi cosmology is decoupled from the standard cosmology, Planck temperature data favour the inclusion of a Bianchi component with a Bayes factor of at least 2.3 units of log-evidence. However, the cosmological parameters that generate this pattern are in strong disagreement with those found from CMB anisotropy data alone. Fitting the induced polarization pattern for this model to the Planck data requires an amplitude of -0.10 +/- 0.04 compared to the value of + 1 if the model were to be correct. In the physically motivated setting, where the Bianchi parameters are coupled and fitted simultaneously with the standard cosmological parameters, we find no evidence for a Bianchi VIIh cosmology and constrain the vorticity of such models to (omega/H)(0) < 7.6 x 10(-10) (95% CL).

    Planck 2015 results XIV. Dark energy and modified gravity2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 594, article id A14Article in journal (Refereed)
    Abstract [en]

    We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG) beyond the standard cosmological constant scenario. We start with cases where the DE only directly affects the background evolution, considering Taylor expansions of the equation of state w(a), as well as principal component analysis and parameterizations related to the potential of a minimally coupled DE scalar field. When estimating the density of DE at early times, we significantly improve present constraints and find that it has to be below similar to 2% (at 95% confidence) of the critical density, even when forced to play a role for z < 50 only. We then move to general parameterizations of the DE or MG perturbations that encompass both effective field theories and the phenomenology of gravitational potentials in MG models. Lastly, we test a range of specific models, such as k-essence, f(R) theories, and coupled DE. In addition to the latest Planck data, for our main analyses, we use background constraints from baryonic acoustic oscillations, type-Ia supernovae, and local measurements of the Hubble constant. We further show the impact of measurements of the cosmological perturbations, such as redshift-space distortions and weak gravitational lensing. These additional probes are important tools for testing MG models and for breaking degeneracies that are still present in the combination of Planck and background data sets. All results that include only background parameterizations (expansion of the equation of state, early DE, general potentials in minimally-coupled scalar fields or principal component analysis) are in agreement with ACDM. When testing models that also change perturbations (even when the background is fixed to ACDM), some tensions appear in a few scenarios: the maximum one found is similar to 2 sigma for Planck TT + lowP when parameterizing observables related to the gravitational potentials with a chosen time dependence; the tension increases to, at most, 3 sigma when external data sets are included. It however disappears when including CMB lensing.

    Planck intermediate results XL. The Sunyaev-Zeldovich signal from the Virgo cluster2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 596, article id A101Article in journal (Refereed)
    Abstract [en]

    The Virgo cluster is the largest Sunyaev-Zeldovich (SZ) source in the sky, both in terms of angular size and total integrated flux. Planck's wide angular scale and frequency coverage, together with its high sensitivity, enable a detailed study of this big object through the SZ effect. Virgo is well resolved by Planck, showing an elongated structure that correlates well with the morphology observed from X-rays, but extends beyond the observed X-ray signal. We find good agreement between the SZ signal (or Compton parameter, y(c)) observed by Planck and the expected signal inferred from X-ray observations and simple analytical models. Owing to its proximity to us, the gas beyond the virial radius in Virgo can be studied with unprecedented sensitivity by integrating the SZ signal over tens of square degrees. We study the signal in the outskirts of Virgo and compare it with analytical models and a constrained simulation of the environment of Virgo. Planck data suggest that significant amounts of low-density plasma surround Virgo, out to twice the virial radius. We find the SZ signal in the outskirts of Virgo to be consistent with a simple model that extrapolates the inferred pressure at lower radii, while assuming that the temperature stays in the keV range beyond the virial radius. The observed signal is also consistent with simulations and points to a shallow pressure profile in the outskirts of the cluster. This reservoir of gas at large radii can be linked with the hottest phase of the elusive warm/hot intergalactic medium. Taking the lack of symmetry of Virgo into account, we find that a prolate model is favoured by the combination of SZ and X-ray data, in agreement with predictions. Finally, based on the combination of the same SZ and X-ray data, we constrain the total amount of gas in Virgo. Under the hypothesis that the abundance of baryons in Virgo is representative of the cosmic average, we also infer a distance for Virgo of approximately 18 Mpc, in good agreement with previous estimates.

    Planck intermediate results XXXIX. The Planck list of high-redshift source candidates2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 596, article id A100Article in journal (Refereed)
    Abstract [en]

    The Planck mission, thanks to its large frequency range and all-sky coverage, has a unique potential for systematically detecting the brightest, and rarest, submillimetre sources on the sky, including distant objects in the high-redshift Universe traced by their dust emission. A novel method, based on a component-separation procedure using a combination of Planck and IRAS data, has been validated and characterized on numerous simulations, and applied to select the most luminous cold submillimetre sources with spectral energy distributions peaking between 353 and 857 GHz at 5' resolution. A total of 2151 Planck high-z source candidates (the PHZ) have been detected in the cleanest 26% of the sky, with flux density at 545 GHz above 500 mJy. Embedded in the cosmic infrared background close to the confusion limit, these high-z candidates exhibit colder colours than their surroundings, consistent with redshifts z > 2, assuming a dust temperature of T-xgal = 35K and a spectral index of beta(xgal) = 1.5. Exhibiting extremely high luminosities, larger than 10(14) L-circle dot, the PHZ objects may be made of multiple galaxies or clumps at high redshift, as suggested by a first statistical analysis based on a comparison with number count models. Furthermore, first follow-up observations obtained from optical to submillimetre wavelengths, which can be found in companion papers, have confirmed that this list consists of two distinct populations. A small fraction (around 3%) of the sources have been identified as strongly gravitationally lensed star-forming galaxies at redshift 2 to 4, while the vast majority of the PHZ sources appear as overdensities of dusty star-forming galaxies, having colours consistent with being at z > 2, and may be considered as proto-cluster candidates. The PHZ provides an original sample, which is complementary to the Planck Sunyaev-Zeldovich Catalogue (PSZ2); by extending the population of virialized massive galaxy clusters detected below z < 1.5 through their SZ signal to a population of sources at z > 1.5, the PHZ may contain the progenitors of today's clusters. Hence the Planck list of high-redshift source candidates opens a new window on the study of the early stages of structure formation, particularly understanding the intensively star-forming phase at high-z.

    Planck intermediate results XLI. A map of lensing-induced B-modes2016In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 596, article id A102Article in journal (Refereed)
    Abstract [en]

    The secondary cosmic microwave background (CMB) B-modes stem from the post-decoupling distortion of the polarization E-modes due to the gravitational lensing effect of large-scale structures. These lensing-induced B-modes constitute both a valuable probe of the dark matter distribution and an important contaminant for the extraction of the primary CMB B-modes from inflation. Planck provides accurate nearly all-sky measurements of both the polarization E-modes and the integrated mass distribution via the reconstruction of the CMB lensing potential. By combining these two data products, we have produced an all-sky template map of the lensing-induced B-modes using a real-space algorithm that minimizes the impact of sky masks. The cross-correlation of this template with an observed (primordial and secondary) B-mode map can be used to measure the lensing B-mode power spectrum at multipoles up to 2000. In particular, when cross-correlating with the B-mode contribution directly derived from the Planck polarization maps, we obtain lensing-induced B-mode power spectrum measurement at a significance level of 12 sigma, which agrees with the theoretical expectation derived from the Planck best-fit Lambda cold dark matter model. This unique nearly all-sky secondary B-mode template, which includes the lensing-induced information from intermediate to small (10 less than or similar to l less than or similar to 1000) angular scales, is delivered as part of the Planck 2015 public data release. It will be particularly useful for experiments searching for primordial B-modes, such as BICEP2/Keck Array or LiteBIRD, since it will enable an estimate to be made of the lensing-induced contribution to the measured total CMB B-modes.

    Abstract [en]

    This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. The temperature and polarization power spectra are consistent with the standard spatially-flat 6-parameter Lambda CDM cosmology with a power-law spectrum of adiabatic scalar perturbations (denoted base Lambda CDM in this paper). From the Planck temperature data combined with Planck lensing, for this cosmology we find a Hubble constant, H-0 = (67.8 +/- 0.9) km s(-1)Mpc(-1), a matter density parameter Omega(m) = 0.308 +/- 0.012, and a tilted scalar spectral index with ns = 0.968 +/- 0.006, consistent with the 2013 analysis. Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters. We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. Combined with the Planck temperature and lensing data, these measurements give a reionization optical depth of tau = 0.066 +/- 0.016, corresponding to a reionization redshift of z(re) = 8.8(-1.4)(+1.7) These results are consistent with those from WMAP polarization measurements cleaned for dust emission using 353-GHz polarization maps from the High Frequency Instrument. We find no evidence for any departure from base Lambda CDM in the neutrino sector of the theory; for example, combining Planck observations with other astrophysical data we find N-eff = 3.15 +/- 0.23 for the effective number of relativistic degrees of freedom, consistent with the value N-eff = 3.046 of the Standard Model of particle physics. The sum of neutrino masses is constrained to Sigma m(v) < 0.23 eV. The spatial curvature of our Universe is found to be very close to zero, with vertical bar Omega(K)vertical bar < 0.005. Adding a tensor component as a single-parameter extension to base Lambda CDM we find an upper limit on the tensor-to-scalar ratio of r(0.002) < 0.11, consistent with the Planck 2013 results and consistent with the B-mode polarization constraints from a joint analysis of BICEP2, Keck Array, and Planck (BKP) data. Adding the BKP B-mode data to our analysis leads to a tighter constraint of r(0.002) < 0.09 and disfavours inflationary models with a V(phi) proportional to phi(2) potential. The addition of Planck polarization data leads to strong constraints on deviations from a purely adiabatic spectrum of fluctuations. We find no evidence for any contribution from isocurvature perturbations or from cosmic defects. Combining Planck data with other astrophysical data, including Type Ia supernovae, the equation of state of dark energy is constrained to w = -1.006 +/- 0.045, consistent with the expected value for a cosmological constant. The standard big bang nucleosynthesis predictions for the helium and deuterium abundances for the best-fit Planck base Lambda CDM cosmology are in excellent agreement with observations. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. In neither case do we find no evidence for new physics. The Planck results for base Lambda CDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. However, as in the 2013 analysis, the amplitude of the fluctuation spectrum is found to be higher than inferred from some analyses of rich cluster counts and weak gravitational lensing. We show that these tensions cannot easily be resolved with simple modifications of the base Lambda CDM cosmology. Apart from these tensions, the base Lambda CDM cosmology provides an excellent description of the Planck CMB observations and many other astrophysical data sets.

    The Simons Observatory: science goals and forecasts2019In: Journal of Cosmology and Astroparticle Physics, ISSN 1475-7516, E-ISSN 1475-7516, no 2, article id 056Article in journal (Refereed)
    Abstract [en]

    The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scientific goals of the experiment, motivate the design, and forecast its performance. SO will measure the temperature and polarization anisotropy of the cosmic microwave background in six frequency bands centered at: 27, 39, 93, 145, 225 and 280 GHz. The initial con figuration of SO will have three small-aperture 0.5-m telescopes and one large-aperture 6-m telescope, with a total of 60,000 cryogenic bolometers. Our key science goals are to characterize the primordial perturbations, measure the number of relativistic species and the mass of neutrinos, test for deviations from a cosmological constant, improve our understanding of galaxy evolution, and constrain the duration of reionization. The small aperture telescopes will target the largest angular scales observable from Chile, mapping approximate to 10% of the sky to a white noise level of 2 mu K-arcmin in combined 93 and 145 GHz bands, to measure the primordial tensor-to-scalar ratio, r, at a target level of sigma(r) = 0.003. The large aperture telescope will map approximate to 40% of the sky at arcminute angular resolution to an expected white noise level of 6 mu K-arcmin in combined 93 and 145 GHz bands, overlapping with the majority of the Large Synoptic Survey Telescope sky region and partially with the Dark Energy Spectroscopic Instrument. With up to an order of magnitude lower polarization noise than maps from the Planck satellite, the high-resolution sky maps will constrain cosmological parameters derived from the damping tail, gravitational lensing of the microwave background, the primordial bispectrum, and the thermal and kinematic Sunyaev-Zel'dovich effects, and will aid in delensing the large-angle polarization signal to measure the tensor-to-scalar ratio. The survey will also provide a legacy catalog of 16,000 galaxy clusters and more than 20,000 extragalactic sources.

    Media, Migration and Integration: An analysis of the media practices of Nigerians in Stockholm Sweden2013Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    This study deals with the issue of migrants and their use of media to facilitate integration and negotiate nostalgia, identity and other social factors that ensue during the analysis of six selected Nigerian migrants in Stockholm.

    By means of a two-step ethnographic approach the empirical material is obtained from documented media use logs and semi-structured interviews of six Nigerian informants in Stockholm. This study sets out to discover the social factors that influence or shape the media practices of Nigerian migrants; furthermore, to understand the concept of nostalgia, integration and more descriptive concept of media use from the perspective such as: the number of years the participants have lived in Sweden, gender and ethnicity.

    The results show the motivation behind the media use of participants with emphasis on how Nigerian migrants use media in terms of type of medium used and frequency of use.

    Additionally, results show how social factors such as: ethnicity, gender, education, work and the number of years lived in Sweden play a role in influencing the media practices of the selected Nigerian migrants in Stockholm while likewise exhibiting a difference in the media practices of participants who have lived in Sweden for the same number of years. In conclusion, results display how the in number of years lived in Sweden in addition to other individual factors played a role in the media use of the participants. The results also show how the participants use media to negotiate nostalgia and ethnic identities.

    Socialt Kapital och föräldraskap: en kvalitativ studie om hur föräldrar söker information, råd och stöd i sitt föräldraskap2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med den här uppsatsen är att undersöka var föräldrar kan söka stöd, råd och information som underlättar deras föräldraskap samt hur detta kan tolkas som olika  former av socialt kapital. Det visar sig tydligt att informationsteknologin med de nya möjligheter som internet innebär, har kommit att få en allt viktigare roll när det gäller att stötta dagens föräldrar. Forskningen inom detta område etablerades på 1990-talet och har visat att internet under 2000-talet har blivit ett allt viktigare forum för föräldrar som söker svar på frågor som rör barn och föräldraskap. Man har kunnat se att de flesta webbforumen vänder sig till kvinnor men att det på senare tid också dykt upp forum som riktar sig till män. De gemenskaper som bildas på nätet har visat sig främja socialt kapital i form av information, känslomässigt stöd och erfarenhetsutbyte. I den här uppsatsen har det visat sig att förutom allt det stöd som internet kan ge i föräldraskapet är fortfarande familjen och samhällets stöd helt avgörande för de flesta föräldrar.  

    Resultatet i denna studie visade att föräldraforumen genom sin ständiga tillgänglighet och möjlighet till erfarenhetsutbyte för många blivit ett viktigt komplement till det stöd som familj, vänner och välfärdssamhället på olika sätt utgör. På grund av tonen och språkbruket i en del forum kan man spåra en viss tveksamhet och kluvenhet inför att aktivt delta i vissa forum. Denna dubbelhet och tendens till social nedvärdering av de som deltar i vissa forum har inte kunnat iakttas i tidigare forskning. Detta kan möjligen bero på att intervjupersonerna inte är utvalda därför att de är aktiva deltagare på föräldraforumen. Studien använder sig av en kvalitativ metod där totalt 10 föräldrar har intervjuats.

    Att aldrig kunna räcka till - Personalens upplevelser av krisbistånd på barnhemmet L.L.C.C.M i Rwanda2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie syftar till att undersöka hur personalen på barnhemmet L.L.C.C.M. påverkas emotionellt av att arbeta med psykiskt traumatiserade barn. Studien belyser forskning kring olika kristeorier och krisbistånd samt vilka risker som kan förekomma för en biståndsperson. Sex kvalitativa semi-strukturerade intervjuer har analyseras genom teoristyrd tematisk analys. Fyra respondenter är rwandier, och två är utländska volontärer.  Resultatet visar att personalen blir påverkad av barnens livsvillkor, men inte i så hög grad att den egna psykiska hälsan blir lidande. Religion, gemenskap eller fysisk aktivitet hjälper respondenterna att bearbeta sina egna reaktioner och motverkar att egna kriser skulle uppstå. En möjlig tolkning till detta resultat är att de har god kunskap om kriser samt en stark förankring i sitt eget liv.

    Home-leaving and Parenthood: Timing of home-leaving and the relation to childbearing behavior in Sweden2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Objective: This thesis examines the timing of having the first child in relation to when Swedish men and women leave the parental home. The aim is to explain if any childbearing trends can be detected based on whether one leaves the parental home at a younger or older relative age than the current age norms. The timing of having the first child might be affected by either a speed up/slow down effect (one continues to experience other stages of adulthood faster or slower relative to people of the same age) or an age-norm effect (one tries to counter-act deviation from the home-leaving norm by speeding up or delaying childbearing to align with people of the same age).

     

    Method and Data: Event history analysis is applied using a multivariate piece-wise constant hazard model. The data comes from Swedish register data based on records of the entire Swedish population between 1 January 1953 and 31 December 2012.

     

    Results: The results indicate that Swedish women who leave the parental home younger than the norm run a greater risk of having their first child sooner after leaving the parental home relative to women of the same age. Swedish men who leave the parental home younger than the norm, on the other hand, run a greater risk of having the first child later after leaving the parental home relative to men of the same age. Swedish men who leave the parental home later than the norm run a greater risk of having their first child sooner after leaving the parental home relative to men of the same age while the opposite is true for women. However, the effects of timing of leaving the parental home are relatively small, which can be explained by the very long and stable mean durations found. The peak durations of intensities, i.e. number of years between leaving the parental home and having the first child, for men and women can be found after 10–12 years. The peak durations of intensities are remarkably similar between the genders.

     

    Conclusion: Swedish women who leave the parental home earlier than the norm are more likely to experience a speed-up effect in terms of childbearing and a slow down effect when leaving the parental home later than the norm. Thus, women stick to breaking the normative timing of the life course events once they have started. Swedish men, on the other hand, are more likely to try and catch up with age norms and instead postpone having the first child when leaving the parental home earlier than the norm and speed up having a child when leaving the parental home later than the norm. Men are thus more likely to time having children with men of the same age.

    Form 20-F: En undersökning av skillnader mellan svensk årsredovisning och Form 20-F2003Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    När svenska företag noterar sig på den amerikanska marknaden är de tvungna att årligen redovisa enligt amerikanska redovisningsprinciper, U.S. GAAP. Detta görs i dokumentet Form 20-F för delge amerikanska intressenter information om företaget. Vad behöver då svenska företag göra för att uppnå de krav som ställs av amerikansk lagstiftning och amerikanska redovisningsprinciper. Vi ska redogöra för vad Form 20-F innehåller och hur dokumentet ser ut. Frågan är, vilka väsentliga skillnader finns då mellan den svenska årsredovisningen och Form 20-F? För att utreda detta har vi intervjuat fyra revisorer samt använt redovisningslitteratur på området från både Sverige och USA. Ví har kommit fram till att Form 20-F är detaljstyrd och formdriven, vilket visar sig genom mängden av krav som ställs från amerikanska myndigheter, att jämföra med den svenska årsredovisningen som är principstyrd. Form 20-F är ett omfattande dokument att upprätta men tar också upp mer information avseende känslighetsanalyer och riskanalyser. Eftersom Form 20-F är formdriven ger det en möjlighet att enkelt jämföra olika företag. Den svenska årsredovisningen har inte samma formkrav eller strikta redovisningspriciper utan det är viktigare att uppvisa en rättvisande bild än att följa varje princip till punkt och pricka. Vi har under arbetets gång skönjt att skillnaderna blivit mindre under ett tioårsperspektiv och att de olika redovisningssätten närmar sig varandra.

    Revisionskvalitet: En utredning av revisorns syn på revisionskvalitet2004Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I efterdyningarna av revisionsskandaler såsom Enron, Worldcom och viss mån även Skandia så känner revisorer av den utsatta situationen som de befinner sig i nuläget. Revisorsyrket har fått sig en törn och allmänheten har fått ett minskat förtroende för revision. Därför är det intressant att utreda vad som gör en revision bra eller dålig utifrån revisors synvinkel. Genom att utröna revisorns åsikt av vad som driver revisionskvalitet så kan man få en ökad förståelse hur revisorer säkerställer att en revision håller tillräcklig kvalitet.

    The Multilingual Forest: Investigating High-quality Parallel Corpus Development2012Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis explores the development of parallel treebanks, collections of language data consisting of texts and their translations, with syntactic annotation and alignment, linking words, phrases, and sentences to show translation equivalence. We describe the semi-manual annotation of the SMULTRON parallel treebank, consisting of 1,000 sentences in English, German and Swedish. This description is the starting point for answering the first of two questions in this thesis.

    • What issues need to be considered to achieve a high-quality, consistent,parallel treebank?

    The units of annotation and the choice of annotation schemes are crucial for quality, and some automated processing is necessary to increase the size. Automatic quality checks and evaluation are essential, but manual quality control is still needed to achieve high quality.

    Additionally, we explore improving the automatically created annotation for one language, using information available from the annotation of the other languages. This leads us to the second of the two questions in this thesis.

    • Can we improve automatic annotation by projecting information available in the other languages?

    Experiments with automatic alignment, which is projected from two language pairs, L1–L2 and L1–L3, onto the third pair, L2–L3, show an improvement in precision, in particular if the projected alignment is intersected with the system alignment. We also construct a test collection for experiments on annotation projection to resolve prepositional phrase attachment ambiguities. While majority vote projection improves the annotation, compared to the basic automatic annotation, using linguistic clues to correct the annotation before majority vote projection is even better, although more laborious. However, some structural errors cannot be corrected by projection at all, as different languages have different wording, and thus different structures.

    Resilience implications of policy responses to climate change2011In: Wiley Interdisciplinary Reviews: Climate Change, ISSN 1757-7780, E-ISSN 1757-7799, Vol. 2, no 5, p. 757-766Article in journal (Refereed)
    Abstract [en]

    This article examines whether some response strategies to climate variability and change have the potential to undermine long-term resilience of social-ecological systems. We define the parameters of a resilience approach, suggesting that resilience is characterized by the ability to absorb perturbations without changing overall system function, the ability to adapt within the resources of the system itself, and the ability to learn, innovate, and change. We evaluate nine current regional climate change policy responses and examine governance, sensitivity to feedbacks, and problem framing to evaluate impacts on characteristics of a resilient system. We find that some responses, such as the increase in harvest rates to deal with pine beetle infestations in Canada and expansion of biofuels globally, have the potential to undermine long-term resilience of resource systems. Other responses, such as decentralized water planning in Brazil and tropical storm disaster management in Caribbean islands, have the potential to increase long-term resilience. We argue that there are multiple sources of resilience in most systems and hence policy should identify such sources and strengthen capacities to adapt and learn.

    Antiplasmodial activity and phytochemical analysis of extracts from selected Ugandan medicinal plants2016In: Journal of Ethnopharmacology, ISSN 0378-8741, E-ISSN 1872-7573, Vol. 186, p. 14-19Article in journal (Refereed)
    Abstract [en]

    Ethnopharmacological relevance: Resistance of the parasites to known antimalarial drugs has provided the necessity to find new drugs from natural products against malaria. The aim of the study was to evaluate the in vitro antiplasmodial activity of some plants used by Traditional Medical Practitioners (TMPs) of Prometra and Rukararwe in malaria treatment in Uganda to provide scientific proof of the efficacies claimed by these Herbalists.

    Materials and methods: The air dried samples of Clerodendrum rotundifolium (leaves), Microglossa pyrifolia (leaves), Momordica foetida (leaves) and Zanthoxylum chalybeum (stem bark) used for malaria treatment by TMPs were successively extracted with ethyl acetate, methanol and water to yield twelve extracts. The extracts were tested against the chloroquine-sensitive (NF54) and chloroquine-resistant (FCR3) Plasmodium falciparum strains in vitro using the micro Mark III test which is based on assessing the inhibition of schizont maturation. A compound A was extracted and purified from the stem bark of Z. chalybeum and its structure was identified and confirmed by spectroscopic methods.

    Results: Most of the extracts tested (92%) showed an antiplasmodial activity with IC50 < 50 mu g/mL. In spite of successive extractions with different solvents, potent anti-plasmodial activity (IC50 < 5 mu g/mL) was observed in the ethyl acetate, methanol and aqueous extracts of M. pyrifolia and C. rotundifolium. Preferential enrichments of activity into water (IC50 < 15 mu g/mL) and Ethyl acetate (IC50 < 5 mu g/mL) were seen in the case of M. foetida and Z chalybeum respectively. The most active extracts were from C rotundifolium and M. pyrifolia with IC50 values less than 2 mu g/mL. Phytochemical analysis of the extracts revealed the presence of saponins, tannins, flavonoids, alkaloids and cardiac glycocides. Fagaramide isolated from Z chalybeum had a higher activity (IC50 2.85 mu g/mL) against the chloroquine-resistant strain than against the chloroquine-senstive (IC50 16.6 mu g/mL) strain used in the study.

    Conclusion: The plant extracts analysed in this study presented an average antiplasmodial activity (58%). This study revealed for the first time the antiplasmodial activity of the plant C. rotundofolium. It's the first time the compound fagaramide (N-isobutyl-3-(3,4-methylene dioxyphenyl) - 2E-propenamide) has been isolated from Z. chalybeum as one of the compounds that contribute to the activity of this plant against P. falciparum.

    Pi0 and eta spectra from proton-antiproton annihilations at rest1984In: Zeitschrift für Physik. C, Particles and fields, ISSN 0170-9739, Vol. 21, no 4, p. 315-319Article in journal (Refereed)
    Abstract [en]

    The low-energy part of the π0 spectrum associated with Mathematical expression annihilation at rest was measured in order to search for bound baryonium-like states. The upper limit for reaching such states via the emission of monochromatic π0’s was found to be 8% per annihilation in the mass region of 1650 MeV. The low-energy part of the η spectrum from Mathematical expression annihilations at rest was also observed.

    The [gamma]-spectrum originating from pp[combining macron] annihilations at rest in liquid hydrogen was measured with two BGO spectrometers. A total of 24 ï¿œ 106[gamma]’s were accumulated. No narrow peaks indicating exotic states such as baryonium were observed. The upper limit for the branching ratio with 1040 [less-than-or-equals, slant] mx [less-than-or-equals, slant] 1770 MeV/c2 and with [lambda]x [less-than-or-equals, slant] 25 MeV/c2 is less than 10-3 with more than 99.96% confidence.

    Search for narrow exotic states in annihilations on 4He1984In: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 138, no 1-3, p. 235-240Article in journal (Refereed)
    Abstract [en]

    After having found evidence for narrow exotic states in p annihilation, the production of such states on a nuclear target was studied with similar techniques. The γ spectrum associated with annihilation on 4He at rest was measured. The spectrum shows two peaks, at energies of 161.9 and 203.0 MeV, corresponding to intermediate narrow states of masses which seem to be related to states found in p annihilations. The confidence is better than 4 σ.

    Progress in mathematics during earlier years in Swedish school2009Conference paper (Other academic)
    Abstract [en]

    Abstract: The results of the improvement in Math between school year 3-4, 5-6-7 and 8-9 in the Swedish school system is analysed using the effect-size estimator. The result shows that the yearly improvement decreases in particular when the pupils reach school year 7-9. The estimate is based on the Swedish version of the international kangaroo competition. A few points on reliability are discussed. The validity of using this particular data is also discussed.

    Where did Technology Go?2009In: Strengthening the Position of Technology Education in the Curriculum / [ed] Arien Becker, Ilja Mottier, Marc J. de Vries, Delft: Delft University of Technology , 2009, p. 1-5Conference paper (Refereed)
    Abstract [en]

    In the beginning there was techne and episteme. Today we have difficulties with finding technology in the implementations of the curriculum in, at least, Swedish schools. So where did it go? I will give arguments that it is all there but it suffers from specialisation. If we think of techne appearing before the different natural science subjects it is a very natural thought that technology today is what is left "between" the more specialized subjects. However I believe that technology is created also in the meeting between two specialized subjects. When a physicist work with a chemist to solve a problem, than this work will very easy appear as technology from one or both parts view. Also not a revolutionary thought this may explain why the Swedish higher education is organized as it is and why we have diffculties to make a working curriculum for the lower grades.

    Experimental study of the inclusive η-spectrum from proton-antiproton annihilations at rest in liquid hydrogen1989In: Zeitschrift für Physik C Particles and Fields, ISSN 0170-9739, E-ISSN 1431-5858, Vol. 42, p. 49-58Article in journal (Refereed)
    Abstract [en]

    The inclusive η-momentum spectrum from Mathematical expression annihilations at rest in liquid hydrogen was measured at LEAR. Branching ratios were obtained for Mathematical expression, and ηη(8.1±3.1)×10-5. An upper limit for Mathematical expression of 1.8×10-4 at 95% CL was found. The ratio of the branching ratios is BR(ηρvariant)/BR(ηω)=0.51-0.06+0.20. For the ratio of branching ratios into two pseudoscalar mesons, we have BR(ηπ0)/BR(π0π0)=0.65±0.14, BR(ηη)/BR(π0π0), BR(ηη′)/BR(π0π0) at 95% CL, and BR(ηη)/BR(ηπ0). © 1989 Springer-Verlag.

    A π0 and η spectrometer of lead glass and BGO for momenta up to 1 GeV/c1986In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 244, no 3, p. 380-390Article in journal (Refereed)
    Abstract [en]

    A spectrometer consisting of two sets of bismuth germanium oxide (BGO) crystals and a lead-glass array has been used to measure the [pi]0 and [eta] momentum spectra produced from proton-antiproton annihilations at rest. We describe the test of the BGO sets in electron beams of energies from 50 to 450 MeV. We discuss the method of construction and calibration of the lead-glass array, as well as procedures to extract the energy and position resolutions for detected photons. A momentum resolution ([sigma]) for [pi]0’s and [eta]’s of 4% and 3%, respectively has been achieved at momenta below 1 GeV/c.

    Social Cohesion in Multicultural Society: A Case of Bangladeshi Immigrants in Stockholm2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Due to the rapid urbanization and globalization, urban social life is getting more complex thanever. Stockholm, the capital city of Sweden, is the residence of about 180 nationalities thatmakes it one of the prominent multicultural cities in Europe. Moreover, sustainable developmentis one of the main goals of the Swedish government. In this circumstance, it is the challenge tomake a socially cohesive society to ensure its social and economic development. This study isaimed to have an inner look at social cohesiveness between Bangladeshi community and otherethnic groups including native Swedish in Stockholm from a qualitative research approach. Asocial cohesion framework has been formulated by analyzing various literatures for the purposeof this study. This social cohesion framework comprises of social, cultural, political andeconomic indicators to understand the different dimensions of social cohesion in Stockholm.This framework is used during preparation of the questionnaire for conducting the qualitativesurvey that includes twelve in-depth interviews. Empirical result reveals that Bangladeshicommunity has a weak sense of belonging and a lack of common identity to the mainstreamsociety, rather they have stronger attachment to other Bangladeshi immigrants in Stockholm.Although lack of social cohesiveness has been found between Bangladeshi immigrants and otherresidents in Stockholm, but many threats to social cohesion (for example; racial conflict) areabsent in Stockholm. Therefore, it is a reachable challenge to make this society cohesive for thebetterment of the country by initiating proper measures.

    Childbearing Behavior Before and After the 1994 Population Policies in Ghana2017In: Population: Research and Policy Review, ISSN 0167-5923, E-ISSN 1573-7829, Vol. 36, no 2, p. 251-271Article in journal (Refereed)
    Abstract [en]

    Due to the high population growth rate in the mid-20th century, the government of Ghana introduced population policies to reduce the growth rate. Encouraging girls' education and increasing contraceptive use were the two main policy measures to reduce population growth. In order to get a clear picture of the childbearing dynamics of Ghanaian women in response to the population policy of 1994, we analyzed individual reproductive histories from 1969 to 2003 using 2003 Ghana Demographic Health survey data to disentangle patterns by parity, calendar period, and educational groups. Exponential hazard regression models were used to estimate the relative risk of births. We find some evidence of a critical juncture in fertility trends, particularly for the fifth child. In addition, higher parity transition rates continuously declined for women with secondary or higher education and these educational levels were achieved by a higher share of the population after the policy was implemented. The 1994 population policy was successful if only by virtue of the increasing number of women with secondary or higher education. Belonging to this group is not only associated with lower fertility, but this suppressing effect strengthened in the years following the policy implementation. We also suspect that the increasing similarity between women with no education and with primary education reflects the diffusion of contraceptive knowledge and norms related to childbearing. The educational reform and contraceptive initiatives did result in increased education and contraceptive awareness and are therefore beneficial programs.

    Perifera kulturer i kontakt?: Indirekt översättning av hebreisk skönlitteratur till svenska2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The following product–oriented study deals with translational norms operating in indirect translation of Hebrew literature into Swedish. The research was conducted as a contrastive study of Extra–linguistic Cultural References (ECR) based on Toury’s (1995/2012) coupled pairs and supplemented with Pedersen’s typology (2011). The material consisted of 3 x 136 coupled pairs excerpted from a collection of short stories written by an Israeli high–prestige writer Amos Oz and translated into Swedish through English. Both translations were carried out by high–prestige translators. The results suggest that indirect literary translation follows the adequacy norm in accordance with the hypothesis on high–prestige translation (Lindqvist 2002). The hypothesis on acceptancy norms operating in indirect translation is rejected.

    Abstract [en]

    Despite receiving relatively little traction in climate change discussions among scholars and policymakers in the early 1990s, the term ‘climate resilience’ is now moving rapidly into prominent policy arenas and academic fora. However, how useful is the term in enabling normative aspirations to reduce net losses to climate change impacts? In this chapter, we first take stock of this seemingly rapid rise in the use of the term by presenting an overview of the progress and ongoing discussions on ‘climate resilience.’ This chapter illustrates these trends based on evidence of the terms’ growth and evolution over the years in two realms: within academia and in public policy. In both cases, we find an increasing trend in the way ‘climate resilience’ is conceptualized and used in academia and in public policy, yet these trends present different challenges and consequences for each case. Taking a problem-oriented approach, we conclude that despite the term’s popularity and growth, a critical review of its measurable effectiveness and pragmatic utility is still needed. Evaluating the terms utility in application is particularly important in light of recent conceptualizations of the climate resilience imperative as ‘transformation’ in a changing climate. We recommend some possible avenues for further research to address this deficit.

    Finns det ett samband mellan olika föräldrastilar och individers framtida känsla av sammanhang?2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Begreppet känsla av sammanhang (KASAM) kan ses som en livshållning som är relaterad till människors förmåga att hantera problem som uppstår i livet. En individs KASAM utvecklas genom socialiseringsprocessen, där föräldrarnas samspel med barnet vanligtvis är central. Hur en förälder förhåller sig till ett barn kan därför ses om en viktig del i barnets utveckling där olika uppfostringsstilar kommer att påverka barnets utveckling gällande olika förmågor. En förälders förhållningssätt till ett barn kan beskrivas i form av olika uppfostringsstilar. Dessa antas relaterade till hur barnet utvecklar olika förmågor, däribland KASAM. Syftet med föreliggande studie var att undersöka sambanden mellan tre olika föräldrastilar (auktoritär, auktoritativ, tillåtande) och KASAM i vuxen ålder. Undersökningsdeltagarna (N=88) som kontaktades via öppna förskolor, besvarade en enkät om uppfostringsstilar och KASAM. Resultaten visar på ett svagt men signifikant samband mellan olika föräldrastilar och några av KASAM:s delkomponenter (hanterbarhet, r = .33, begriplighet, r = .22, r = -.27) ), men inget signifikant samband erhölls mellan föräldrastil och individens totala KASAM poäng. Mot bakgrund av att en individs KASAM visat sig avgörande för hälsa och ohälsa hos vuxna individer, visar resultatet av föreliggande studie att vidare forskning om hur olika föräldrastilar påverkar en individs KASAM är av relevans.

    Abstract [en]

    A format is described for a scale bar that encodes the length represented within the structure of the bar itself, thereby removing the need for any supporting text. Although the 'unitary' scale bar has a conventional appearance it is also machine readable and therefore retains information about the scale even when the file format is changed. The format is based on the metre and is suitable for all terrestrial applications.
