- The Himalayan rivers yield the most significant flux of continental sediments into the ocean. Organic matter (OM) transported by these rivers provides a peek at the influence of diverse geological terrains, soil types, vegetation, and climate on carbon cycling within a narrow boundary. We analyzed suspended and bedload sediments from four Himalayan rivers to trace their sources, elucidate their fate during fluvial transport, and estimate the organic carbon (OC) flux. Hence, total OC (TOC), dissolved organic carbon (DOC), C:N ratios, and lignin phenols were measured. Consistent with the erosional intensity in the rivers, suspended sediment load input followed the order: Kaligandaki > Myagdikhola > Aadhikhola > Tinahukhola. C:N values in rivers from the Lesser Himalayas and Siwalik indicate sediments from mixed biogenic sources. In contrast, high TOC and C/N values in the trans-Himalaya rivers flowing through barren landscapes reflect the erosion of catchment sediments yielding petrogenic carbon. The suspended matter in rivers from the Lesser Himalayas and Siwalik has higher lignin phenol concentrations than the trans-Himalaya and Higher Himalaya rivers. The lignin phenol ratios indicate higher degradation in rivers from the trans and Higher Himalaya sections. This implies that only a small fraction of the terrestrial OM transported by these rivers deposits in the ocean sink. In contrast, rivers from the Lesser Himalayas and Siwaliks sequester a significant amount of OM bound to their bedload. As a result, these rivers transferred lower particulate OC (POC) but higher DOC than similar rivers worldwide. Rivers from Lesser Himalayas and Siwaliks transfer > 90 % of annual POC flux during monsoons. Finally, although Himalayan rivers transport less OC than other global rivers traversing densely vegetated landscapes, the sheer number of these rivers has significant implications on the fate and transport of total OC from catchments sediments.

Approaches to Safeguarding Sustainability Requirements in Public Construction Projects – the Client’s Perspective
- 2016

Ingår i: CIB World Building Congress 2016.

Konferensbidrag (refereegranskat)abstract
- In recent years, the concept of sustainability has penetrated much of modern political, social and industrial discourse. Its recent popularization, stemming from the Brundtland report of 1987, has led to sustainability becoming a household term in nearly every industry, of which the construction sector is no exception. Considering the importance that sustainability has in the construction industry, and how it is particularly emphasized in construction financed by public funds, questions need to be raised in terms how capable the construction client is in meeting and achieving the sustainability requirements, often set by politics, that exist whilst safeguarding project delivery. The study is based on four interviews targeting public clients in Sweden and it investigates how sustainability requirements are managed in large public construction projects. What is of particular interest is the degree to which public client organizations either develop or procure systems/staff to ensure that the criteria for social, environmental and cultural sustainability are maintained and that the consequences of different approaches are managed. The results support the idea of having a multifaceted approach to sustainable construction, arguing that terms such as social and cultural sustainability may instead be dealt with separately from the more strictly defined sustainability terms of toxicity, waste and energy consumption. There is also a suggestion that once the client organization begins incorporating a sustainability mind-set in all of its affairs, members of that organization may begin working with sustainability on a perfunctory basis without necessarily understanding the underlying reasons for their actions. Finally, the challenge with sustainability is perhaps not so much that there is a lack of capability as much as there is a lack of resources for working with sustainability.

- Artificial Intelligence (AI) reshapes companies and how innovation management is organized. Consistent with rapid technological development and the replacement of human organization, AI may indeed compel management to rethink a company’s entire innovation process. In response, we review and explore the implications for future innovation management. Using ideas from the Carnegie School and the behavioral theory of the firm, we review the implications for innovation management of AI technologies and machine learning-based AI systems. We outline a framework showing the extent to which AI can replace humans and explain what is important to consider in making the transformation to the digital organization of innovation. We conclude our study by exploring directions for future research. © 2020 The Author(s)

Socioeconomic inequalities in low birth weight in South Asia : A comparative analysis using Demographic and Health Surveys
- 2022
-
Ingår i: SSM - Population Health. - : Elsevier BV. - 2352-8273. ; 20

Tidskriftsartikel (refereegranskat)abstract
- Background: Low Birth Weight (LBW) continues to be a prominent universal cause of various short- and long-term health hazards throughout infancy and adulthood. However, no study has revealed the socioeconomic inequalities in LBW among South Asian countries. This study assesses the socioeconomic inequalities among under-five South Asian children with LBW. Methods: Secondary data were derived from six (Afghanistan, Bangladesh, India, Maldives, Nepal, and Pakistan) nationally representative South Asian Demographic and Health Surveys conducted between 2015 and 2021, and included 170,547 under-five years of age children. The study employed the concentration curve and concentration index to assess the socioeconomic inequalities of those with LBW. Additionally, mixed-effect logistic regression was applied to determine the factors associated with LBW. Results: A significant negative concentration index indicates the wealth-related and education-related inequalities of LBW among under-five South Asian children. LBW is highly concentrated in the socio-economically poor section of the society. Our study found statistically significant negative concentration index in all South Asian countries: Afghanistan (Education: -0.108), Bangladesh (wealth: -0.070 & education: -0.083), India (wealth: -0.059 & education: -0.052), Nepal (by wealth: -0.064 & by education: -0.080), and Pakistan (by wealth: -0.080 & by education: -0.095). Findings from the mixed-effects logistic regression model also show that children from the poorest quintiles (AOR: 1.53, 95% CI: 1.41–1.67) and illiterate mothers (AOR: 1.39, 95% CI: 1.29–1.51) had higher odds of being afflicted with LBW compared to the wealthiest quintiles and educated mothers respectively. Women's pregnancy assessments, such as antenatal care utilisation, iron supplementation intake, and normal delivery mode, are significantly correlated with decreased odds of children's LBW. Conclusion: There exists a strong association between LBW cases and socioeconomic inequalities among South-Asian children below five years of age. This indicates the urgent need for health education and prenatal care services for women from Afghanistan, Bangladesh, India, Nepal, and Pakistan, especially those with lower socioeconomic status.

Making Citizens: Theories and Practices of Constructing Citizenship Identities
- 2010
-
Ingår i: Diversity, Inclusion and Citizenship in Scandinavia. - 9781443825740 ; , s. 215-240
-
Bokkapitel (refereegranskat)abstract
- The point of departure in this chapter is that citizenship is constructed and re-constructed through both formal regulations and societal practice. Hence citizenship is understood both as formal relations between the state and the individual, manifested in constitutional rights and duties, but also as a social citizenship that depends on prevailing power relations. Being included as a citizen thus concerns, on the one hand, having equal constitutional rights and duties as others in society, and, on the other, having these rights in practice―in other words―having an experienced substantive citizenship. This chapter aims to explore different aspects of citizenship theories that contribute to an analysis of the construction of citizens and the experience of citizenship. It illustrates how these theories can help us understand the opportunities and obstacles encountered by unemployed immigrant women who wish to become citizens in practice.

Tidskriftsartikel (refereegranskat)abstract
- Abdominal obesity is a key contributor of metabolic disease. Recent trials suggest that dietary fat quality affects abdominal fat content, where palmitic acid and linoleic acid influence abdominal obesity differently, while effects of n-3 polyunsaturated fatty acids are less studied. Also, fatty acid desaturation may be altered in abdominal obesity. We aimed to investigate cross-sectional associations of serum fatty acids and desaturases with abdominal obesity prevalence in a population-based cohort study. Serum cholesteryl ester fatty acids composition was measured by gas chromatography in 60-year old men (n = 1883) and women (n = 2015). Cross-sectional associations of fatty acids with abdominal obesity prevalence and anthropometric measures (e.g., sagittal abdominal diameter) were evaluated in multivariable-adjusted logistic and linear regression models, respectively. Similar models were employed to investigate relations between desaturase activities (estimated by fatty acid ratios) and abdominal obesity. In logistic regression analyses, palmitic acid, stearoyl-CoA- desaturase and Delta 6-desaturase indices were associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals) for highest versus lowest quartiles were 1.45 (1.19-1.76), 4.06 (3.27-5.05), and 3.07 (2.51-3.75), respectively. Linoleic acid, alpha-linolenic acid, docohexaenoic acid, and Delta 5-desaturase were inversely associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals): 0.39 (0.32-0.48), 0.74 (0.61-0.89), 0.76 (0.62-0.93), and 0.40 (0.33-0.49), respectively. Eicosapentaenoic acid was not associated with abdominal obesity. Similar results were obtained from linear regression models evaluating associations with different anthropometric measures. Sex-specific and linear associations were mainly observed for n3-polyunsaturated fatty acids, while associations of the other exposures were generally non-linear and similar across sexes. In accordance with findings from short-term trials, abdominal obesity was more common among individuals with relatively high proportions of palmitic acid, whilst the contrary was true for linoleic acid. Further trials should examine the potential role of linoleic acid and its main dietary source, vegetable oils, in abdominal obesity prevention.

Fluid flow and mass transfer in an inductively stirred four-ton melt of molten steel: A comparison of measurements and predictions

Tidskriftsartikel (refereegranskat)abstract
- Experimental measurements are reported on melt velocities and on the rate at which immersed carbon rods dissolve in a 4-ton induction furnace, holding a low carbon steel melt. These measurements are compared with theoretical predictions, based on the numerical solution of Maxwell's equations and the turbulent Navier-Stokes equations. In general, good agreement has been obtained, both regarding the absolute values of the velocities and the mass transfer coefficients and the trends predicted by the theoretical analysis. In addition to providing further proof regarding the applicability of the mathematical modeling technique, the principal contribution of the work is that it provides an improved insight into the behavior of inductively stirred melts. In particular it was found that for an inductively stirred melt both the velocities and the rate of turbulence energy dissipation are relatively uniform spatially, in contrast to bubble stirred systems, where most of the agitation is confined to the jet plume and to the near surface region. It was found, furthermore, that the mass transfer coefficient characterizing the rate of dissolution of immersed carbon rods depends both on the absolute values of the melt velocity and on the local values of the turbulence intensity; thus significant mass transfer will occur in the region of the eye of the circulation, where the absolute value of the mean velocity is small. © 1984 The Metallurgical of Society of AIME.
