PARAMETER SENSITIVITY MAPS OF SURFACE GEOELECTRIC ARRAYS II. NONLINEAR AND FOCUSSED ARRAYS
No full textIn this paper we present, at first time in a geophysical journal, parameter sensitivity
maps of nonlinear and focussed electrode arrays. We present them as anomalies
due to electric dipoles forming on opposing surfaces of an elementary cube within the
subsurface at three different depths, and not only the total effect of the dipole, but
also of its components are shown. Parameter sensitivity maps of non-linear arrays,
compared to those of linear arrays, have in general 1. more equal sensitivity values
in x and y directions, 2. more chances for antisymmetry axes, 3. smoother lateral
distribution of sensitivity values. We recommend a systematic use of parameter sensitivity
maps in geoelectric prospecting, both in planning and interpretation of field
measurements
Kvinnans sociala status i norrön mytologi : Alternativa tolkningar
No full textIn this paper the author has read and compared The Poetical Edda, and Margaret Clunies-Ross' book, Prolonged echoes: Old norse myth in medieval northern society(1998). The aim of this paper is to offer alternative interpretations to the ones Clunies-Ross has made by drawing on The Poetical Edda and other sources. Margaret Clunies-Ross' interpretations left much unaccounted for by giving one-sided analyses of love, marriage, status and family relations. She simply focused on the female as the one who gets undermined in all of these categories. Modin finds that this is a very narrow perspective of the gender dynamics in Norse mythology, especially after reading The Poetical Edda. She is not alone in her opinion. There is much evidence that contradicts Clunies-Ross' theories which the author of this paper aims to clarify by offering new perspectives on these texts. She also gives the reader examples of parts in Norse mythology that are not only interpreted differently from Clunies-Ross, but also several other authors, such as Catharina Ingelman-Sundberg, Peter Andreas Munch, John Lindow et cetera
Vems är det reproduktiva ansvaret? En spegling av genus betydelse vid biståndsbedömning av försörjningsstöd
No full textAbstract Author: Sanne Modin, Matilda Berggren Title: Who has the reproductive responsibility? – A reflection of gender roles in work with financial assistance [translated title] Supervisor: Yvonne Johansson Assessor: With this study our intent were to examine the Swedish social services workers view on financial assistance to contraceptive use. We wanted to look at this subject from a gender perspective. To our help we interviewed seven social workers whom work with financial assistance. These interview persons works in two different municipalities with a various number of inhabitants. To our study we used the qualitative method and semi-structured interviews. The questions were divided into different themes where sexuality, contraceptives and gender were the main issues. With help from gender theories we then analyzed the responses from the social workers and also using relevant research regarding sexual and contraceptive health. Our conclusion is that gender is an influencing factor in the daily work with financial assistance. In questions regarding parental leave and contraceptive use the gender order is still dominant. A reason for this could be the work load for the social workers and also the fact that none of our interview persons had been educated in matters regarding equality between women and men. This study’s result should be considered a guideline rather than a veracity since it is a small study with a minor group of interview persons
Plasma-Assisted Synthesis of Co3O4-Based Electrocatalysts on Ni Foam Substrates for the Oxygen Evolution Reaction
No full textElectrocatalytic oxygen evolution reaction (OER) plays a key role in sustainable energy conversion and storage, but is severely hampered by the lack of efficient catalysts, whose development remains a critical and challenging issue. Herein, it is reported for the first time that pure and Fe2O3-containing Co3O4-based OER electrocatalysts are grown on highly porous Ni foams by plasma enhanced-chemical vapor deposition and/or radiofrequency sputtering. Thanks to the inherent advantages of cold plasma synthesis routes, Ni foam supports are efficiently infiltrated by Co3O4 nanostructures and eventually nanosized Fe2O3, allowing a fine-tuning of their mutual content, nano-organization, and oxygen defectivity. For Co3O4-Fe2O3 systems, these issues enable current densities up to ≈120 mA cm−2 at 1.79 V versus the reversible hydrogen electrode, an overpotential of ≈350 mV at 10 mA cm−2 and a Tafel slope as low as 60 mV dec−1, favorably comparing with literature values for most cobalt-based OER catalysts reported so far. Such features, accompanied by a good time stability, represent an important goal for eventual practical applications and candidate the proposed fabrication route as a valuable tool for the design of efficient electrocatalysts with precisely engineered properties and based on naturally abundant transition elements
Intellektuellt kapital under pandemi och krig : En kvantitativ studie på 90 Large Cap- och Small Cap-företag
No full textTitel: Intellektuellt kapital under pandemi och krig - En kvantitativ studie på 90 Large Cap- och Small Cap-företag Nivå: Examensarbete på grundnivå (kandidatexamen) i ämnet företagsekonomi Författare: Emma Modin och Emma Carpman Handledare: Veronika Larsson Datum: 2025 - juni Syfte: Syftet med denna studie är att analysera Large Cap- och Small Cap-företags frivilliga redovisning av intellektuellt kapital i samband med Covid-19-pandemin och Rysslands invasion av Ukraina. Metod: Vi har använt en kvantitativ metod i form av innehållsanalys i denna studie där ett index av sökord kopplade till intellektuellt kapital skapats. Därefter, med hjälp av binär kodning, har vi undersökt om orden förekommit i 90 börsnoterade svenska företags engelska årsredovisningar från 2018 och 2023. Med datan har vi genomfört t-test, ANOVA-test och regressionsanalys för att undersöka våra hypoteser och besvara studiens syfte. Resultat och slutsats: Studien visar att den frivilliga redovisningen av intellektuellt kapital i snitt har ökat i de 90 svenska företagen från 2018 till 2023. Dessutom visar resultaten att den kategori av intellektuellt kapital företagen redovisade mest efter kriserna var strukturellt kapital. Vidare visar studien att företag noterade på Large Cap redovisade mer intellektuellt kapital än företag noterade på Small Cap både 2018 och 2023. Arbetets bidrag: Studien bidrar till tidigare forskning genom att undersöka den frivilliga redovisningen av intellektuellt kapital i samband med två kriser som inte har studerats tillsammans tidigare. Dessutom bidrar vårt arbete till forskningen kring signaleringsteorin då vi undersöker huruvida stora företag frivilligt redovisar mer intellektuellt kapital än mindre företag, i samband med de studerade kriserna. Förslag till fortsatt forskning: Vi föreslår att genomföra en studie lik vår efter att världsläget har stabiliserat sig, för att kunna säkerställa att den ökade redovisningen av intellektuellt kapital beror på de undersökta globala kriserna. Dessutom hade ett kvalitativt arbete eventuellt tydligare kunna hänföra ökningen av intellektuellt kapital till de studerade kriserna.

Method: We have implemented a quantitative method in the form of a content analysis where an index of keywords related to intellectual capital has been created. We have then used binary coding to examine whether the keywords have appeared in 90 Swedish listed companies' English annual reports from 2018 and 2023. Using the data we have conducted t-tests, ANOVA-tests and regression analysis to examine our hypotheses and answer the aim. Results and conclusions: This study shows that the voluntary disclosure level of intellectual capital on average has increased in the 90 Swedish companies from 2018 to 2023. The study also shows that the category of intellectual capital that companies reported the most after the crises was structural capital. Furthermore, the study shows that companies listed on Large Cap reported more intellectual capital than companies listed on Small Cap in both 2018 and 2023. Contribution of the thesis: The study contributes to previous research by examining the voluntary accounting of intellectual capital in connection with two crises that have not been studied together before. Additionally, our work contributes to the research on signaling theory by examining whether large companies voluntarily report more intellectual capital than smaller companies in connection with the studied crises. Suggestions for future research: We propose to conduct a study similar to ours once the global situation has stabilized, to ensure that the increased reporting of intellectual capital is a result of the global crises examined. In addition, qualitative work could possibly more clearly attribute the increase in intellectual capital to the crises studied. Key words: intellectual capital, voluntary disclosure, COVID-19-pandemic, war, global crisi

Cocaine use and the risk for endocarditis in intravenous drug users
No full textEndocarditis is a relatively frequent infection in intravenous drug users. We compared features in the cases of 102 patients with those in intravenous drug users with other causes of fever to identify risk factors predictive of endocarditis. Logistic regression analysis showed cocaine use to be strongly associated with endocarditis. This special risk involving cocaine use has not been reported previously; the explanation for it may provide insight into the pathogenesis of endocarditis
Examples of G-Hom-Associative Algebras
No full textIn this thesis we look at hom-associative algebras (which turn out to be exactly the G1-hom-associative algebras), by, in two and three dimensions, trying to find the structure constants for which an algebra becomes hom-associative when the homomorphism is defined as different matrix units. These algebras are also hom-Lie admissible (or G6-hom-associative, which turn out to be the same thing) with a commutator, so we also find the commutator for each of these hom-Lie admissible algebras. We end up finding every hom-associative and hom-Lie algebra for defined as each 2×2 matrix unit in two dimensions, each 3×3 matrix unit in three dimensions when the problem is mapped to one dimension, for three 3×3 matrix units in three dimensions when the problem is mapped to two dimensions (but with the commutators not having been calculated), and only a few hom-associative algebras and hom-Lie algebras for one 3×3 matrix unit in the full three dimensions. We also compare the results for the different values of , and find that in dimensions it is possible to find the values of the structure constants for all 2 different :s simply by finding all of the solutions for different :s (chosen in a specific way) and then permutating all of the indices
