  • Relationship Between Frugal and Inclusive Innovation and Digital Employment Solutions (DES): A Review
  • 2021. - 3
  • Ingår i: Human Interaction, Emerging Technologies and Future Applications III. - Switzerland : Springer, Cham. - 9783030553074 - 9783030553067 ; , s. 398-403

    • Inclusive and frugal innovations are the key to managing workforce potential of the underdeveloped regions of South Asia (SA). Digital employment solutions (DES) can help to improve the targeted mobility of labour between developed and underdeveloped regions and countries. This research explores the relationship between frugal and inclusive innovations and DES. This review study analyses 16 articles to investigate this relationship. The study found direct and indirect relationships among frugal and inclusive innovations, DES and the employment situation in developed and underdeveloped regions and countries. Frugal innovations and DES may be an appropriate solution to tackle the employment problems in SA but cultural, social and economic barriers can affect the success of the overall process. Researchers and policymakers should, however, carefully evaluate the nature of target regions, the degree of cooperation and evaluation of various related barriers.

  • Pregnancy outcomes after exposure to interferon beta : a register-based cohort study among women with MS in Finland and Sweden
  • 2020
  • Ingår i: Therapeutic advances in neurological disorders. - : Sage Publications. - 1756-2856 .- 1756-2864. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Our aim was to estimate and compare the prevalence of adverse pregnancy outcomes among pregnant women with multiple sclerosis (MS) exposed to interferon beta (IFNB) and among women with MS unexposed to any MS disease-modifying drug (MSDMD).Methods: This cohort study used Finnish (1996-2014) and Swedish (2005-2014) national register data. Women with MS having IFNB dispensed 6 months before or during pregnancy as the only medication were considered as IFNB exposed (only IFNB-exposed), whereas women with MS unexposed to any MSDMD were considered unexposed (MSDMD-unexposed). Prevalence was described and compared using log-binomial or logistic regression and adjusted for potential confounders including maternal age and comorbidity.Results: Among 2831 pregnancies, 2.2% of the only IFNB-exposed and 4.0% of the MSDMD-unexposed women had serious adverse pregnancy outcomes [elective termination of pregnancy due to foetal anomaly (TOPFA), major congenital anomaly (MCA) in live, or stillbirth]. After adjustments, the prevalence of serious adverse pregnancy outcomes was lower among the only IFNB-exposed compared with the MSDMD-unexposed [relative risk 0.55, 95% confidence interval (CI) 0.31-0.96]. The prevalence of individual outcomes, including MCA, spontaneous abortions, and stillbirths was not increased with IFNB exposure. Women with MS exposed to IFNB appeared more likely to terminate their pregnancy for reasons other than foetal anomaly, compared with MSDMD-unexposed pregnant MS patients (odds ratio 1.71, 95% CI 1.06-2.78).Conclusion: In this large cohort study, no increase in the prevalence of adverse pregnancy outcomes was observed in women with MS exposed to IFNB compared with MS patients unexposed to any MSDMDs. This study together with other evidence led to a change in the labels of the IFNB products in September 2019 in the European Union, and IFNB use today may be considered during pregnancy, if clinically needed.

  • Preservation of microscopic fur, feather, and bast fibers in the Mesolithic ochre grave of Majoonsuo, Eastern Finland
  • 2022
  • Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 17:9
  • Tidskriftsartikel (refereegranskat)abstract
    • The study of animal and plant fibers related to grave furnishing, garments, and grave goods in thousands-of-year-old burials provides new insights into these funerary practices. Their preservation presupposes favorable conditions, where bacterial and fungal activity is at a minimum, as in anaerobic, wet, salty, arid, or frozen environments. The extreme acidic-soil environments (i.e., podzols) of Finland pose a challenge when it comes to studying funerary deposits, as human remains are rarely found. However, its potential to preserve microparticles allows us to approach the funerary event from a totally different point of view. Here, we present the first multiproxy analyses of a Mesolithic deposit from Finland. A red-ochre burial of a child found in Majoonsuo is studied by analyzing 1) microscopic fibers, 2) fatty acids, and 3) physical-chemical (CIELab color, pH, grain size) properties of 60 soil samples and associated materials. The microscopic fibers evidenced the remains of waterfowl downy feathers, a falcon feather fragment, canid and small rodent hairs as well as bast fibers. These could have been used in furnishing the grave and as ornaments or clothes. Canid hairs could belong to a dog inhumation, or more likely to canid fur used as grave good/clothes. Samples with microparticles have more long-chain and unsaturated fatty acids, although animal species identification was not possible. Soil properties indicate that the burial was made in the local soil, adding homogeneous red ochre and removing the coarser material; no bioturbation was found. The highly acidic sandy soil, together with a slight increase in finer particles when ochre is abundant, probably resulted in micro-scale, anoxic conditions that prevented bacterial attack. This study reveals the first animal hairs and feathers from a Finnish Mesolithic funerary context, and provides clues about how their preservation was possible.
