This study investigates how communication consultants struggle to reconstruct their professional role in the digital media landscape. The extant literature on professional roles in public relations has a tendency to render roles as static pregivens. Therefore, the purpose of this study is to contribute conceptually and empirically to role research by focusing on the process of “role-making” and ho
We discuss exclusive elastic double diffractive axial-vector χc (1+) meson production in proton-antiproton collisions at the Tevatron. The amplitude for the process is derived within the kt-factorization approach with unintegrated gluon distribution functions (UGDFs). We show that the famous Landau-Yang theorem is not applicable in the case of off-shell gluons. Differential cross sections for diff
It has been argued that innovation increasingly depends on external knowledge sources. It is still unclear if relations to particular knowledge sources or to a broad variety of sources matter for innovation. Also, there is a debate on the issue which spatial levels are most relevant. In this context, we investigate the importance for ICT firms in Austria of variety in knowledge sourcing for their
Context. The prediction of the Planck-constrained primordial lithium abundance in the Universe is in discordance with the observed Li abundances in warm Population II dwarf and subgiant stars. Among the physically best motivated ideas, it has been suggested that this discrepancy can be alleviated if the stars observed today had undergone photospheric depletion of lithium. Aims. The cause of this d
It is widely believed that deciduous tundra-shrub dominance is increasing in the pan-Arctic region, mainly due to rising temperature. We sampled dwarf birch (Betula nana L.) at a northeastern Siberian tundra site and used dendrochronological methods to explore the relationship between climatic variables and local shrub dominance. We found that establishment of shrub ramets was positively related t
This literature review seeks to map the state of research on the effects of digitization on personal financial behavior and management through a bibliometric analysis and a systematic literature review. The findings indicate that current knowledge is primarily based on perspectives of actors in commerce and systems development. More research is needed on how personal financial behavior change in r
Maximizing the performance of crystal monochromators is a key aspect in the design of beamline optics for diffraction-limited synchrotron sources. Temperature and deformation of cryo-cooled crystals, illuminated by high-power beams of X-rays, can be estimated with a purely analytical model. The analysis is based on the thermal properties of cryo-cooled silicon crystals and the cooling geometry. De
DERA, 2-deoxyribose-5-phosphate aldolase, catalyzes the retro-aldol cleavage of 2-deoxy-ribose-5-phosphate (dR5P) into glyceraldehyde-3-phosphate (G3P) and acetaldehyde in a branch of the pentose phosphate pathway. In addition to the physiological reaction, DERA also catalyzes the reverse addition reaction and, hence, is an interesting candidate for bio-catalysis of carbo-ligation reactions, which
Sulfonate ester hydrolysis has been the subject of recent debate, with experimental evidence interpreted in terms of both stepwise and concerted mechanisms. In particular, a recent study of the alkaline hydrolysis of a series of benzene arylsulfonates (Babtie et al., Org. Biomol. Chem. 10, 2012, 8095) presented a nonlinear Brønsted plot, which was explained in terms of a change from a stepwise mec
BACKGROUND: Recent advancements in Alzheimer's disease (AD) biomarker research and clinical trials prompt reflection on the value and consequently appropriate use of tau positron emission tomography (tau-PET) in the future. METHODS: We conducted an online survey among dementia and PET experts worldwide to investigate the anticipated future role of tau-PET in clinical practice and trials. RESULTS:
Stress is a public health concern. One of the explanations to why women, more than men, receive stress-related diagnosis in connection to sickness absence is their responsibility for housework and caregiving. We investigate men’s and women’s time allocation and its association with everyday stress across life course stages (25-74 years), using individual time diary data (N=11,880) from the 2000/01
Artificial Intelligence (AI) has been described as a great hope but also a threat to fulfilling the social goals of sustainable development, where one critical aspect is providing society with a safe and secure environment. At the same time, interdisciplinary analyses that connect the social effects of artificial intelligence with security issues have been relatively sparse. Accordingly, this arti
The molecular characteristics of the pseudoautosomal region (PAR) of sex chromosomes remain elusive. Despite significant genome-sequencing efforts, the PAR of highly differentiated avian sex chromosomes remains to be identified. Here we use linkage analysis together with whole-genome re-sequencing to uncover the 630-kb PAR of an ecological model species, the collared flycatcher. The PAR contains 2
This article examines the early development of South Korean intercountry adoption to Sweden. It focuses particularly on two disruptions in the movement of children between the two nations, drawing on archival sources in Sweden, South Korea, and Denmark. The article demonstrates that South Korean–Swedish adoption was deeply bound up in the shifting Cold War relations within and between the Korean p
Overactivity of the angiotensin-type-1 receptor (AT1)/NADPH-oxidase axis enhances aging processes, neuroinflammation and neurodegeneration. The role of AT2 receptors in the above-mentioned AT1-related effects in the aged brain, particularly substantia nigra, was investigated in this study. In the nigra, we observed a progressive decrease in AT2 mRNA expression with aging, and AT2 deletion led to c
Collaboration with Swedish trio Kv.Arken. Premiere of the piece "Sånger från Svartsten" written specifically for the trio’s unique composition, drawing inspiration from both Swedish and Ukrainian folk tunes. Mats has found inspiration for the work from, among other things, Gammelsvenskby and the Jewish klezmer tradition in Ukraine, as well as from the farm Svartsten in Gåsborn in Värmland, where h
