Lifestyle enterprising: the "ambiguity work" of Swedish horse-farmers

The article introduces the concept of ambiguity work as a specific form of work-life balancing performed when making a livelihood based on leisure interests and a personal lifestyle. The study focuses on female self-employed horse-farmers in Sweden involved in service work with and through horses. Through an analysis of narratives and practices of this service work, based on ethnographic interview

Immediate responses in soil chemistry, vegetation and ground beetles to soil perturbation when implemented as a restoration measure in decalcified sandy grassland

The species-rich calcareous grassland communities in Europe are gradually disappearing due to lack of management such as grazing or cultivation, resulting in decalcification and reduction of gaps in the vegetation. In this study, experimental soil perturbation (deep and shallow) was performed in degenerated sandy grassland in plots with a size of 8 x 8 m, using a randomised block design. The hypot

Molecular phylogeny of Lymantriinae (Lepidoptera, Noctuoidea, Erebidae) inferred from eight gene regions

To understand the evolutionary history of Lymantriinae and test the present higher-level classification, we performed the first broad-scale molecular phylogenetic analysis of the subfamily, based on 154 exemplars representing all recognized tribes and drawn from all major biogeographical regions. We used two mitochondrial genes (cytochrome c oxidase subunit I and 16S ribosomal RNA) and six nuclear

Host-dependent control of early regulatory and effector T-cell differentiation underlies the genetic susceptibility of RAG2-deficient mouse strains to transfer colitis

De novo differentiation of CD4(+) Foxp3(+) regulatory T cells (induced (i) Tregs) occurs preferentially in the gut-associated lymphoid tissues (GALT). We addressed the contribution of background genetic factors in affecting the balance of iTreg, T helper type 1 (Th1), and Th17 cell differentiation in GALT in vivo following the transfer of naive CD4(+) CD45RB(high) T cells to strains of RAG2-defici

Large area quasi-free standing monolayer graphene on 3C-SiC(111)

Large scale, homogeneous quasi-free standing monolayer graphene is obtained on cubic silicon carbide, i.e., the 3C-SiC(111) surface, which represents an appealing and cost effective platform for graphene growth. The quasi-free monolayer is produced by intercalation of hydrogen under the interfacial, (6 root 3 x 6 root 3)R30 degrees-reconstructed carbon layer. After intercalation, angle resolved ph

Dissociative subtypes in posttraumatic stress disorders and hypnosis: Neurocognitive parallels and clinical implications.

Converging evidence suggests that heterogeneity in posttraumatic stress disorder (PTSD) arises from the presence of discrete subtypes of patients, one of which is characterized by elevated dissociative symptoms. A similar dissociative subtype has been observed among individuals displaying high hypnotic suggestibility. Here we highlight important parallels between these subtypes, drawing from resea

Encoding of social signals in all three electrosensory pathways of Eigenmannia virescens.

Extracting complementary features in parallel pathways is a widely used strategy for a robust representation of sensory signals. Weakly electric fish offer the rare opportunity to study complementary encoding of social signals in all of its electrosensory pathways. Electrosensory information is conveyed in three parallel pathways: two receptor types of the tuberous (active) system and one receptor

Mother Tongue, Host Country Earnings, and Return Migration: Evidence from Cross-National Administrative Records

Using a unique database constructed through the merging of administrative records from Sweden and Finland, we provide the first detailed examination of differential return migration risks by people's mother tongue within a given nationality. We analyze whether the divergence in return migration risk between Swedish-speaking and Finnish-speaking Finns in Sweden relates to host country earnings, con

Autophagy and ER-stress contribute to photoreceptor degeneration in cultured adult porcine retina.

The aim of this study was to investigate rod and cone photoreceptor degeneration in organotypic cultures of adult porcine retina. Our hypothesis was that the photoreceptors accumulate opsins, which, together with exposure to cyclic dim light illumination, induce autophagy and endoplasmic reticulum stress (ER-stress) to overcome damaging protein overload. For this purpose, retinas were cultured for

Cyclic and linear monoterpenes in phospholipid membranes: Phase behavior, bilayer structure, and molecular dynamics.

Monoterpenes are abundant in essential oil extracted from plants. These relatively small and hydrophobic molecules have shown many important biological fucntions, including antimicrobial activity and membrane penetration enhancement. The interaction between the monoterpenes and lipid bilayers is considered important to the understanding of the biological functions of monoterpenes. In this study we

Cheyne-Stokes respiration is not related to quality of life or sleepiness in heart failure

Background and aims: The effects of central sleep apnea in Cheyne-Stokes respiration on sleep-related symptoms and quality of life are not very well established. We aimed to investigate whether Cheyne-Stokes respiration is related to health-related quality of life. We also studied the impact on daytime sleepiness and nocturnal dyspnea. Methods: Included were 203 consecutive patients, stabilized fo

Human introductions create opportunities for intra-specific hybridisation in an alien lizard

Introduction of individuals from multiple sources could create opportunities for hybridization between previously isolated lineages, which may impact on the invasion process. Identifying the phylogeographic origin of introduced populations is therefore an important task to further test the causes and consequences of human-mediated translocations. The common wall lizard (Podarcis muralis) shows a s

Flavonoid and lignan intake in relation to bladder cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

Background:There is growing evidence of the protective role of dietary intake of flavonoids and lignans on cancer, but the association with bladder cancer has not been thoroughly investigated in epidemiological studies. We evaluated the association between dietary intakes of total and subclasses of flavonoids and lignans and risk of bladder cancer and its main morphological type, urothelial cell c

'Sexual interaction or a solitary action: Young Swedish men's ideal images of sexual situations in relationships and in one-night stands

Objective It seems that traditional gender norms influence young women's and men's sexuality differently. However, little attention has been paid to ideal images of sexual situations. This study identifies young heterosexual men's ideal images of sexual situations and their expectations of themselves in sexual situations. Study design The present study employs a qualitative design. Twelve Swedish

Impact of sex on perinatal mortality and morbidity in twins

Objective: Twin studies offer opportunities to investigate mechanisms underlying sex-associated differences in perinatal outcomes. The objective of the study was to investigate sex-related differences in perinatal complications. Study design: A cohort of 16,045 twin pregnancies 32,090 twins - was explored for obstetric complications, perinatal and infant mortality, and neonatal morbidities. Result

Dendroclimatology in Fennoscandia - from past accomplishments to future potential

Fennoscandia has a strong tradition in dendrochronology, and its large tracts of boreal forest make the region well suited for the development of tree-ring chronologies that extend back several thousands of years. Two of the world's longest continuous (most tree-ring chronologies are annually resolved) tree-ring width chronologies are found in northern Fennoscandia, with records from Tornetrask an
