Wikipedia, heterotopi och versioner av kulturella minnen

The article draws together studies on encyclopaedic expressions throughout history with Foucault's notion of heterotopia, i.e. actually existing utopias or ‘other’, particular spaces that exist besides society's regular spaces and which work according to their own rules. It explores how we can understand contemporary online encyclopaedias, specifically Wikipedia, as digital heterotopias. For this

Subsequent Risks of Parkinson Disease in Patients with Autoimmune and Related Disorders: A Nationwide Epidemiological Study from Sweden.

Objectives: To investigate associations between autoimmune disorders and Parkinson disease (PD), and to study whether the risk is associated with follow-up time and age. Methods: Standardized incidence ratios (SIRs) were calculated for PD in patients with autoimmune disorders by comparing them to subjects without autoimmune disorders. Results: Among 310,522 patients with a total of 33 conditions o

U-Pb baddeleyite and zircon ages of 2040 Ma, 1650 Ma and 885 Ma on dolerites in the West African Craton (Anti-Atlas inliers): Possible links to break-up of Precambrian supercontinents

Precambrian inliers of the Anti-Atlas belt in the southern part of Morocco contain numerous dolerite dyke and sill swarms which were previously poorly dated. Four dykes and two sills dated by the U-Pb TIMS method on baddeleyite and zircon provide the first steps toward a magmatic 'barcode' for the West African Craton (WAC) and constraints on the timing of breakup of the WAC from Precambrian superc

An enormous amorphous silica stock in boreal wetlands

We investigated amorphous Si (ASi) in a boreal wetland in northern Sweden. We found enormous stocks of ASi in the upper soil layers (up to 11% of dry weight), in the form of diatom frustules and plant ASi. A consistent exponential decrease in ASi concentrations was observed with increasing depth in the soil profile. An inverse modeling approach shows that vegetation takes up a substantial part of

Validation and comparison of two soil-vegetation-atmosphere transfer models for tropical Africa

This study aims to compare and validate two soil-vegetation-atmosphere-transfer (SVAT) schemes: TERRA-ML and the Community Land Model (CLM). Both SVAT schemes are run in standalone mode (decoupled from an atmospheric model) and forced with meteorological in-situ measurements obtained at several tropical African sites. Model performance is quantified by comparing simulated sensible and latent heat

Trimming Down a Protein Structure to Its Bare Foldons SPATIAL ORGANIZATION OF THE COOPERATIVE UNIT

Folding of the ribosomal protein S6 is a malleable process controlled by two competing, and partly overlapping, folding nuclei. Together, these nuclei extend over most of the S6 structure, except the edge strand beta 2, which is consistently missing in the folding transition states; despite being part of the S6 four-stranded sheet, beta 2 seems not to be part of the cooperative unit of the protein

Perceived Utility (not Sympathy) Mediates the Proportion Dominance Effect in Helping Decisions

The proportion dominance effect (PDE) refers to a higher motivation to help when the victims are part of a small (you can help 56 out of 60) rather than a large (you can help 56 out of 560) reference group. In two studies using different experimental paradigms, we investigated possible mediators of the PDE. Study 1 (N = 168) was conducted in three separate steps in order to test each link of the m

Structural aspects of N-glycosylations and the C-terminal region in human glypican-1.

Glypicans are multifunctional cell surface proteoglycans involved in several important cellular signalling pathways. Glypican-1 (Gpc1) is the predominant heparan sulphate (HS) proteoglycan in the developing and adult human brain. The two N-linked glycans and the C-terminal domain that attaches the core protein to the cell membrane are not resolved in the Gpc1 crystal structure. Therefore we have s

Causally Redundant Social Objects: Rejoinder to Elder-Vass

In Elder-Vass’s response to my (2014) it is maintained: (1) that a social object is not identical with but is merely composed of its suitably interrelated parts; (2) that a social object is necessarily indistinguishable in terms of its causal capacities from its interrelated parts; and (3) that ontological individualism lacks an adequate ontological justification (Elder-Vass forthcoming). In this

Film Music and Visual Attention : A Pilot Experiment using Eye-Tracking

This article gives an account of an eye-tracking experiment carried out during a workshop at Lund University, where the overall question was, "how does film music affect meaning?". The pilot experiment was conducted on an exploratory basis, and in this article, the tentative results and possible usefulness of laboratory experiments are discussed.

Dissociated control as a signature of typological variability in high hypnotic suggestibility

This study tested the prediction that dissociative tendencies modulate the impact of a hypnotic induction on cognitive control in different subtypes of highly suggestible individuals. Low suggestible (LS), low dissociative highly suggestible (LDHS), and high dissociative highly suggestible (HDHS) participants completed the Stroop color-naming task in control and hypnosis conditions. The magnitude

Bryophyte colonization history of the virgin volcanic island Surtsey, Iceland

The island Surtsey was formed in a volcanic eruption south of Iceland in 1963–1967 and has since then been protected and monitored by scientists. The first two moss species were found on Surtsey as early as 1967 and several new bryophyte species were discovered every year until 1973 when regular sampling ended. Systematic bryophyte inventories in a grid of 100 m × 100 m quadrats were made in 1971

Losing the Issue, Losing the Vote: Issue Competition and the Reform of Unemployment Insurance in Germany and Sweden

Welfare state research tends to assume strong and enduring public support for welfare state institutions. We challenge this assumption and show that in times of economic crisis, positive welfare state attitudes are confronted with conflicting preferences for improvement of labour market performance. We argue that such movements in public opinion have led to issue competition among major political

Bernoulli convolutions and 1D dynamics

We describe a family phi(lambda) of dynamical systems on the unit interval which preserve Bernoulli convolutions. We show that if there are parameter ranges for which these systems are piecewise convex, then the corresponding Bernoulli convolution will be absolutely continuous with bounded density. We study the systems phi(lambda) and give some numerical evidence to suggest values of lambda for wh

Site-Specific Protonation Kinetics of Acidic Side Chains in Proteins Determined by pH-Dependent Carboxyl (13)C NMR Relaxation.

Proton-transfer dynamics plays a critical role in many biochemical processes, such as proton pumping across membranes and enzyme catalysis. The large majority of enzymes utilize acid-base catalysis and proton-transfer mechanisms, where the rates of proton transfer can be rate limiting for the overall reaction. However, measurement of proton-exchange kinetics for individual side-chain carboxyl grou

Performance of enhanced liver fibrosis plasma markers in asymptomatic individuals with ZZ α1-antitrypsin deficiency.

OBJECTIVES: Alpha1-antitrypsin deficiency (AATD) is a common genetic cause of chronic liver disease. According to retrospective studies, up to 25% of those with homozygous ZZ (Glu 342 to Lys) AATD suffer from liver cirrhosis and/or liver cancer in late adulthood. We hypothesized that the plasma markers for liver fibrosis, necrosis, and apoptosis may identify AATD individuals at higher risk for liv

Solid-to-fluid DNA transition inside HSV-1 capsid close to the temperature of infection.

DNA in the human Herpes simplex virus type 1 (HSV-1) capsid is packaged to a tight density. This leads to tens of atmospheres of internal pressure responsible for the delivery of the herpes genome into the cell nucleus. In this study we show that, despite its liquid crystalline state inside the capsid, the DNA is fluid-like, which facilitates its ejection into the cell nucleus during infection. We
