- Feminism in the Nordic countries was primarily formulated in terms of ‘state feminism’. The women’s movement cooperated with feminist government officials and politicians, resulting in societies that can be considered to be the most gender-equal societies in the world. Historically, the state provided for a large publicly-financed welfare sector which made it possible for many women to combine work and family through the state’s implementation of family-friendly policies, while simultaneously providing employment opportunities for many women. However, since the financial crisis of the 1990s, there has been a political change influenced by neo-liberal thought, in which politicians have handed over the welfare state’s responsibilities to the market, and, instead, the politicians have encouraged entrepreneurship, not least among women. Further to this development, there has been a change in emphasis from entrepreneurship (understood as starting and running a business) to entrepreneurialism which, in addition to a belief in the efficacy of market forces, also contains a social dimension where individuals are supposed to be flexible and exercise choice. In this article, we ask whether this entails a change in the feminist project in the Nordic countries, and if so, what the likely consequences are for this project, both in practice and in research. In order to answer this question, we reviewed existing Nordic research on women’s entrepreneurship and examined how this body of work conceptualizes entrepreneurship, gender, the state, and equality. We also considered whether any trends could be identified. We relate our findings to recent changes in government policy and conclude that the current discourse on entrepreneurship challenges, and possibly weakens, state feminism, but we also conclude that this discourse may also provide space for new forms of feminist action, in market terms. We coin the term FemInc.ism to denote feminist action through enterprise and we discuss a number of important challenges that research on this phenomenon is faced with.

- Test statistics for sphericity and identity of the covariance matrix are presented, when the data are multivariate normal and the dimension, p, can exceed the sample size, n. Under certain mild conditions mainly on the traces of the unknown covariance matrix, and using the asymptotic theory of U-statistics, the test statistics are shown to follow an approximate normal distribution for large p, also when p >> n. The accuracy of the statistics is shown through simulation results, particularly emphasizing the case when p can be much larger than n. A real data set is used to illustrate the application of the proposed test statistics.

- Ahmad et al. (in press) presented test statistics for sphericity and identity of the covariance matrix of a multivariate normal distribution when the dimension, p, exceeds the sample size, n. In this note, we show that their statistics are robust to normality assumption, when normality is replaced with certain mild assumptions on the traces of the covariance matrix. Under such assumptions, the test statistics are shown to follow the same asymptotic normal distribution as under normality for large p, also whenp >> n. The asymptotic normality is proved using the theory of U-statistics, and is based on very general conditions, particularly avoiding any relationship between n and p.

- An intraclass correlation coefficient observed in several populations is estimated. The basis is a variance-stabilizing transformation. It is shown that the intraclass correlation coefficient from any elliptical distribution should be transformed in the same way. Four estimators are compared. An estimator where the components in a vector consisting of the transformed intraclass correlation coefficients are estimated separately, an estimator based on a weighted average of these components, a pretest estimator where the equality of the components is tested and then the outcome of the test is used in the estimation procedure, and a James-Stein estimator which shrinks toward the mean.

- The role of inflammation and the mechanism of tendon healing after rupture has historically been a matter of controversy. The purpose of the present study is to investigate the role of mast cells and their relation to the NMDA receptor-1 (a glutamate receptor) during healing after Achilles tendon rupture. Eight female Sprague Dawley rats had their right Achilles tendon transected. Three weeks after rupture, histological quantification of mast cell numbers and their state of degranulation was assessed by histochemistry. Co-localization of mast cell tryptase (a mast cell marker) and NMDA receptor-1 was determined by immunofluorescence. The intact left Achilles tendon was used as control. An increased number of mast cells and a higher proportion of degranulated mast cells were found in the healing Achilles tendon compared to the intact. In addition, increased co-localization of mast cell tryptase and NMDA receptor-1 was seen in the areas of myotendinous junction, mid-tendon proper and bone tendon junction of the healing versus the intact tendon. These findings introduce a possible role for mast cells in the healing phase after Achilles tendon rupture.

- The development of a species-specific conservation protocol that involves artificial insemination with frozen semen needs to validate an effective methodology for freezing semen. Colloid centrifugation has been suggested and widely applied as an effective tool for selecting animal spermatozoa for artificial breeding. The objective of the present study was to compare different methods of centrifugation, single layer using Androcoll-Bear and Percoll and double layer using PureSperm 100 (in two different discontinuous gradients 40%-80% and 45%-90%), for the selection of fresh brown bear sperm samples. In the before freezing group, all selected samples showed a higher progressive motility and viability (except Percoll for motility 43.0 +/- 5.3 [P < 0.051); all colloids except PureSperm 45/90% rendered samples with fewer damaged acrosomes. In the after thawing group, all tested centrifugation colloids showed a good capacity to decrease the number of damaged acrosomes. Furthermore, PureSperm treatment (45/90%) resulted in an increase in apoptotic-like changes not only immediately after thawing but also after the incubation test, leading us to suggest that this gradient could induce some kind of deleterious effects on the sperm samples. On the other hand, PureSperm treatment (40/80%) yielded a quality preservation capacity similar to Androcoll-Bear in number of damaged acrosomes, different relative to the control (control, 5.3 +/- 0.6; PureSperm 80, 2.0 +/- 0.3; Androcoll, 2.1 +/- 0.9 [P < 0.051) but a decrease in the number of viable spermatozoa recovered after thawing relative to the control (control, 21.2 +/- 3.1; PureSperm 80, 13.7 +/- 2.7 [P < 0.051). In conclusion, Androcoll-Bear constitutes a useful tool for handling of brown bear ejaculates owing to its simple handling and procedure with a reliable sperm selection and freezability. This colloid yielded an improvement in several sperm parameters in brown bear frozen-thawed semen; the selected spermatozoa of fresh samples with this colloid showed a better resistance to freezing compared with the control sample not only for motility but also for viability.

Tidskriftsartikel (refereegranskat)abstract
- Background: The epidemiology of the zoonotic tick-transmitted parasite Babesia spp. and its occurrence in wild reservoir hosts in Sweden is unclear. In European deer, several parasite species, including Babesia capreoli and the zoonotic B. venatorum and B. divergens has been reported previously. The European roe deer, Capreolus capreolus, is an important and common part of the indigenous fauna in Europe, as well as an important host for Ixodes ricinus ticks, the vector of several Babesia spp. in Europe. Here, we aimed to investigate the occurrence of Babesia spp. in roe deer in Sweden. Findings: Roe deer (n = 77) were caught and sampled for blood. Babesia spp. was detected with a PCR assay targeting the 18S rRNA gene. The prevalence of Babesia spp. was 52 %, and two species were detected; B. capreoli and B. venatorum in 44 and 7.8 % of the individuals, respectively. Infection occurred both in summer and winter. Conclusions: We showed that roe deer in Sweden, close to the edge of their northern inland distributional range, are infected with Babesia spp. The occurrence of B. venatorum in roe deer imply that it is established in Sweden and the zoonotic implication of this finding should be regarded to a greater extent in future.

- Roads may act as barriers to animal movements, but direct barrier effects on insects have rarely been studied. In this study we collected data on bees and wasps along two sides of a large road in Sweden using yellow pan traps. We then analyzed if the species composition differed between the two sides of the road; first for the whole community, and then only for the smallest species (which typically are poorer dispersers). As a complement, we analyzed if different vegetation variables differed between the two sides of the road, as this may also affect differences in species composition. Finally, we analyzed if species richness and abundance in general differed between the two sides and how these two response variables were explained by the vegetation variables. There was a significant difference in species composition between the eastern and the western side of the road when analyzing the whole community, and this relationship became even stronger when the largest species were excluded. The vegetation variables did not strongly differ between the two sides, and there was no difference in species richness and abundance of bees and wasps either. Abundance was, however, explained by the number of flowering plants in the surroundings of the trap. Even though using a rather limited data set, our results indicate that large roads may act as barriers on the movement of bees and wasps, especially for small species with poor dispersal ability. On the other hand, road verges may be important habitat for many species, which leads to a potential conflict that is important to consider in the planning of green infrastructure.

- Barley landraces from Northern Europe formgenetically distinct latitudinal groups, suggestingthat adaption plays an important role inthe geographical distribution of genetic diversity.Here, we investigate how Northern Europeanbarley landraces relate to landraces fromother parts of Europe and whether candidategenes for climate adaption can be identified.For this purpose, 27 barley landraces, availableas century-old seed specimens, were genotypedwith a 384 single nucleotide polymorphism(SNP) assay. Landraces from the Nordiccountries formed a genetically distinct grouprelative to landraces from Central and SouthernEurope. Polymorphic positions in the floweringtime genes HvCO1, HvFT1, Ppd-H1, and VRN1-H1 were genotyped. The previously known alleledistribution of Ppd-H1 with the responsive allelepresent in the South and the nonresponsiveallele in the North was confirmed. The otherthree genes were more variable in Central andSouthern Europe compared to the North andneither of the flowering time genes showedany geographically correlated variation withinthe Nordic countries. Allelic frequencies fromthe 384 SNP set were correlated with climaticvariables. This allowed us to identify five SNPsputatively associated with length of growth season,and two SNPs putatively associated withprecipitation. The results show how historicalcrop specimens can be used to study howgenetic variation has been geographically distributedand the genetics of adaption.

- OBJECTIVES: This study investigates the frequency and characteristics of carbapenemase-producing Escherichia coli/Klebsiella pneumoniae (CPE/K) and extended-spectrum cephalosporinase-producing E. coli/K. pneumoniae (ESCE/K) in healthy humans and livestock in rural Cambodia. Additionally, household practices as risk factors for faecal carriage of ESCE/K are identified.METHODS: Faecal samples were obtained from 307 humans and 285 livestock including large ruminants, pigs and poultry living in 100 households in rural Cambodia in 2011. Each household was interviewed, and multilevel logistic model determined associations between household practices/meat consumption and faecal carriage of ESCE/K. CPE and ESCE/K were detected and further screened for colistin resistance genes.RESULTS: CPE/K isolates harbouring blaOXA-48 were identified in two humans. The community carriage of ESCE/K was 20% in humans and 23% in livestock. The same ESBL genes: blaCTX-M-15 , blaCTX-M-14 , blaCTX-M-27 , blaCTX-M-55 , blaSHV-2 , blaSHV-12 , blaSHV-28 ; AmpC genes: blaCMY-2 , blaCMY-42, blaDHA-1 ; and colistin resistance genes: mcr-1-like and mcr-3-like were detected in humans and livestock. ESCE/K was frequently detected in women, young children, pigs and poultry, which are groups in close contact. The practice of burning or burying meat waste and not collecting animal manure indoors and outdoors daily were identified as risk factors for faecal carriage of ESCE/K.CONCLUSIONS: Faecal carriage of E. coli and K. pneumoniae harbouring extended-spectrum cephalosporinase genes are common in the Cambodian community, especially in women and young children. Exposure to animal manure and slaughter products are risk factors for intestinal colonization of ESCE/K in humans.
