Malafouris (2013) proposes that agency is an emergent product of the relational ontology of our material engagement. However, I suggest a distinction between meaning and agency for a better understanding of our relational ontology with things. Meaning is the payoff of the relational ontology, meaning emerges when an agent act within the world. Agency is the capability to act, signify, produce and

In spite of our good intentions and explicit egalitarian convictions, we habitually disfavor the underprivileged. The rapidly growing literature on implicit bias – unconscious, automatic tendencies to associate negative traits with members of particular social groups – points towards explanations of this dissonance, although rarely towards generalizable solutions. In a recent paper, Jennifer Saul

To explain the coexistence of economic freedom and big government, this paper distinguishes between big government in the fiscal sense of requiring high taxes, and big government in the Hayekian sense of requiring knowledge that is difficult to acquire from a central authority. The indicators of government size in measures of economic freedom capture the fiscal size but ignore the Hayekian knowled

BACKGROUND AND OBJECTIVES: Kidd blood group system consists of two major antigens: Jka and Jkb . Both the antigens are absent in individuals typed as Jknull and may develop clinically significant anti-Jk3 antibody. Screening donors for provision of Jknull blood is an ongoing task for blood centres with Jknull blood units kept frozen for specific requirements. In 2016, we discovered a previously ty

BACKGROUND: ABO subtypes are characterized by the alteration of antigens present and their expression levels on red blood cells and many are linked to genetic changes in the ABO gene. Weakened expression of antigens should be identified to prevent transfusion reactions or ABO-incompatible transplantations. Genotyping can be applied to identify subtypes to complement serologic testing. Next-generat

The increased risk for fracture with age is associated not only with reduced bone mass but also with impaired bone quality. At the microscale, bone quality is related to porosity, microstructural organization, accumulated microdamage and intrinsic material properties. However, the link between these characteristics and fracture behavior is still missing. Bone tissue has a complex structure and as

We evaluated a structured education- and exercise-based self-management program for patients with knee or hip osteoarthritis (OA), using a registry-based study of data from 44,634 patients taken from the Swedish “Better Management of Patients with Osteoarthritis” registry. Outcome measures included a numeric rating scale (NRS), EuroQol five dimension scale (EQ-5D), Arthritis self-efficacy scale (A

Corynebacterium is a genus that can contaminate blood cultures and also cause severe infections like infective endocarditis (IE). Our purpose was to investigate microbiological and clinical features associated with contamination and true infection. A retrospective population-based study of Corynebacterium bacteremia 2012–2017 in southern Sweden was performed. Corynebacterium isolates were species

Tunneling field-effect transistors (TFET) based on a vertical gate-All-Around (VGAA) nanowire (NW) architecture with a core-shell (CS) structure have been explored for future CMOS applications. Performance predictions based on a tight-binding mode-space NEGF technique include a drive current \mathrm{I}-{\mathrm{o}\mathrm{n}} of 6.7\ \mu \mathrm{A} (NW diameter \mathrm{d}= 10.2\ \mathrm{nm}) at \ma

Histatin 5, an intrinsically disordered protein (IDP) found in the saliva, has been investigated in two studies, and in two different perspectives. In the first study, the structural properties of a conjugated histatin 5 fragment is characterized in an effort to explain its enhanced fungicidal properties. It was discovered that the conjugated molecule, spermidine, does not affect the conformation

Scanning small-angle x-ray scattering (SAXS) measurements were performed on 36 formalin-fixed reast tissue biopsies obtained from two patients. All samples contained microcalcifications of ype II, i.e. ormed by hydroxyapatite. We demonstrate the feasibility of classifying breast lesions by canning SAXS of issues containing microcalcifications with a resolution of 35 μm x30 μm. We eport a character

Det ropas allt högre om att forskare ska samverka med det omgivande samhället. Det är rop som vittnar om en stor tilltro till att morgondagens vetenskapliga genombrott garanteras genom att kunskap produceras i samverkan. Men vad betyder det att samverka? Är den alltid att föredra? Främjar eller kanske rentav hotar samverkan kunskapsproduktion i samhället?Denna essäsamling syftar till att belysa oc

We have studied the geometry and electronic structure of the P-cluster in nitrogenase in four oxidation states: PN, P1+, P2+, and P3+. We have employed combined quantum mechanical and molecular mechanical (QM/MM) calculations, using two different density-functional theory methods, TPSS and B3LYP. The calculations confirm that the side chain of Ser-188 is most likely deprotonated in the partly oxid

Tunnel Field-Effect Transistors (TFETs) are an emerging alternative to CMOS for ultralow power and neuromorphic applications. The off current (Ioff) and, hence, the subthreshold swing (S) in these devices are limited by ambipolarity, which degrades its capabilities in complementary circuits. Here, we investigate experimentally vertical InAs/InGaAsSb/GaSb nanowire TFETs with gate-drain underlap as

What can a music teacher do in a school where half of the students belong to minority cultures? In music education research there are many reports on the important role music has in preventing social exclusion. These reports refer to music’s power to serve both as aim and means to build efficient learning environments in multicultural schools (see for example Bamford, 2006; Bauer, 2005; Beck, 1993

The evolution from a Goods-dominant logic (GD-logic) into a Service-dominant logic (SD-logic) is marked by fundamental changes in how we leverage resources for innovation. The current paper offers a review of SD-logic resources within the field of Information Systems (IS). It uses a scoping review method of papers from the senior scholars’ basket of journals and the two flagship IS conferences: EC

In this Letter, we report on the creation of hard x-ray beams carrying orbital angular momentum of topological charge −ℏ and −3ℏ at a photon energy of 8.2 keV via spiral phase plates made out of fused silica by ultrashort-pulsed laser ablation. The phase plates feature a smooth phase ramp with a 0.5 μm nominal step height and a surface roughness of 0.5 μm. The measured vortex beams show submicrome

Two in situ 'nanoreactors' for high-resolution imaging of catalysts have been designed and applied at the hard X-ray nanoprobe endstation at beamline P06 of the PETRA III synchrotron radiation source. The reactors house samples supported on commercial MEMS chips, and were applied for complementary hard X-ray ptychography (23 nm spatial resolution) and transmission electron microscopy, with additio
