Does socially desirable responding produce exaggerated correlations between self-ratings of personality and positive psychology constructs? We operationalized social desirability as the evaluative factor, i.e. the tendency to react to evaluative content in questionnaire items and related one standard measure and one evaluatively neutralized measure of the Big Five to measures of five key positive

European forests are being shaped by active human use and management, and by harvesting of wood in particular. Yet, our understanding of how forests are harvested across Europe is limited, as the real harvest regimes are not well described by currently available data. Here, we analyse recent harvests, as observed in permanent plots of forest inventories in 11 European countries, totaling to 182,64

Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground-based long-term forest monitoring with large-scale remote sensing. We surveyed the metadata from 466 865 forest monitoring plots

The longitudinal motion and the intramural shear strain of the arterial wall increase dramatically in response to blood pressure, thereby impacting the vascular wall microenvironment. Exposure to a sedentary lifestyle has been identified as an independent risk factor for cardiovascular disease, but it has been shown that intermittent physical activity embedded into everyday life is enough to impro

This research explores the impact of structural variations in laminarins derived from seaweed on their immunomodulatory properties. Laminarins from Laminaria digitata, L. hyperborea, and Saccharina latissima, were obtained using a two-step water extraction protocol, followed by structural characterization by FT-IR spectroscopy, 1H NMR, and MALDI-TOF MS. The laminarin backbones were confirmed as β–

Sveriges högsta elkostnader är resultatet av Kraftringens spretighet och dess historiskt höga benägenhet att investera i allsköns misslyckade projekt långt utanför Lunds kommungräns, skriver Lars Jonung, professor emeritus i nationalekonomi på Lunds universitet och Jan Rydenfelt, tidigare finansdirektör.

We explore how the Resilient Urban Food Systems (RUFS) project applied a theory of change approach to raise awareness of the importance of smallholder farmers and to bring them into decision making processes, as key players working towards a sustainable and resilient food system in Kasese Municipality and Mbale City in Uganda. Critical inputs from using a theory of change approach included: consta

Human reproductive success requires both producing children and making investments in the development of offspring. To a large extent these investments are made by the parents of the child, but researchers are now looking beyond the nuclear family to understand how extended kin, notably grandmothers, enhance reproductive success by making transfers to progeny of different kinds. The extent to whic

The deterioration of fibre-reinforced sprayed concrete was studied in the Oslofjord subsea tunnel (Norway). At sites with intrusion of saline groundwater resulting in biofilm growth, the concrete exhibited significant concrete deterioration and steel fibre corrosion. Using amplicon sequencing and shotgun metagenomics, the microbial taxa and surveyed potential microbial mechanisms of concrete degra

Efter regn kommer sol – och har man tur får man se en vackert lysande regnbåge. I Bibeln skapar Gud den som ett löfte om att inga fler syndafloder ska komma. I irländsk folktro finns en skatt vid regnbågens slut, och i den nordiska mytologin förbinder den människornas värld med Asgård. Men vad är regnbågen egentligen, och hur funkar den?

Confinement of reactants within nanoscale spaces of low-dimensional materials has been shown to provide reorientation of strained reactants or stabilization of unstable reactants for synthesis of molecules and tuning of chemical reactivity. While few studies have reported chemistry within zero-dimensional pores and one-dimensional nanotubes, organic reactions in confined spaces between two-dimensi

Light-emitting diodes (LEDs) have been investigated during the past decades, for which a major challenge is total internal reflection that limits the light extraction efficiency. ‘Nanotree’ LEDs elegantly solve this bottleneck. Lower band gap nanowire branches are grown on higher band gap core wires. Charge carriers diffuse into the branches and recombine there. Total internal reflection is impede

We present processed light emitting diodes (LED) devices based on GaInP core-branch nanowire (NW) structures. The LEDs rely on the charge carrier diffusion induced light emitting diode concept. The GaInP core has a higher Ga content than the branches to induce diffusion of carriers from the cores into the branches. The branches play the role of the active region in the structure, where charge carr

The recent discovery of well-preserved fragments of Sphenothallus in the Central Clare Group (Pennsylvanian) of western Ireland provides new insights into the morphology of this enigmatic, putative cnidarian. The specimens demonstrate a morphological plasticity, including features not previously described for Sphenothallus, such as the presence of flat sides and angular lateral margins, non-bilate

The in-flow focusing method, introduced herein, enables rapid and straightforward measurements of the whole-channel acoustic energy of acoustic flow-through devices. The method is applied to assess the whole-channel acoustic energy and acoustophoretic efficiency frequency spectra of a bottom-actuated silicon-glass and a side-actuated glass chip. The input variables are the time-independent geometr
