Disentangling ‘ecosystem services’ and ‘nature’s contributions to people’

People depend on functioning ecosystems, which provide benefits that support human existence and wellbeing. The relationship between people and nature has been experienced and conceptualized in multiple ways. Recently, ecosystem services (ES) concepts have permeated science, government policies, multi-national environmental agreements, and science–policy interfaces. In 2017, the Intergovernmental

Intact cord resuscitation versus early cord clamping in the treatment of depressed newborn infants during the first 10 minutes of birth (Nepcord III) - a randomized clinical trial

Background: Experiments have shown improved cardiovascular stability in lambs if umbilical cord clamping is postponed until positive pressure ventilation is started. Studies on intact cord resuscitation on human term infants are sparse. The purpose of this study was to evaluate differences in clinical outcomes in non-breathing infants between groups, one where resuscitation is initiated with an in

Value Destruction in Swedish Welfare Services : Frontline Workers’ Impact on Asylum-Seeking Minors’ Possibilities of Creating Value in Early Integration

The aim of this article is to investigate ways in which welfare frontline workers’ conceptualization of Swedishness destroys asylum-seeking minors’ (16–17 years) possibilities of creating value during the service process in early integration. Focus group interviews and in-depth interviews were conducted with coaches at accommodation centres, schoolteachers and social workers. The analytical approa

Intercalation of cationic peptides within Laponite layered clay minerals in aqueous suspensions : The effect of stoichiometry and charge distance matching

Clays can be synthesised to have specific functional properties, which have been exploited in a range of industrial processes. A key characteristic of clay is the presence of a negatively charged surface, surrounded by an oppositely charged rim. Because of that, clays are able to sequester cationic compounds resulting in the formation of ordered layered structures, known as tactoids. Recent resear

Production of Perdeuterated Proteins in Escherichia coli for Structural Studies by Neutron Crystallography

Neutron macromolecular crystallography (NMX) is a complementary technique to X-ray crystallography leveraging neutron scattering properties of the hydrogen isotope deuterium (2H). Production of deuterium labelled molecules together with large crystal requirements for neutron crystallography are few of several bottlenecks limiting implementation of this technique for a wider range of proteins.

Plasma neurofilament light associates with Alzheimer's disease metabolic decline in amyloid-positive individuals

Introduction: Neurofilament light chain (NfL) is a promising blood biomarker to detect neurodegeneration in Alzheimer's disease (AD) and other brain disorders. However, there are limited reports of how longitudinal NfL relates to imaging biomarkers. We herein investigated the relationship between blood NfL and brain metabolism in AD. Methods: Voxelwise regression models tested the cross-sectional

A One Health – One World initiative to control antibiotic resistance : A Chile - Sweden collaboration

Controlling antibiotic resistance is a global concern. The One Health initiative has provided a strategy to deal with this problem efficiently within a country. However, due to the global nature of the problem it is paramount not only to focus on specific countries, but to establish ways to avoid the development of antibiotic resistance in different geographical regions. In this letter, we propose

Rhegmatogenous Retinal Detachment in Nonsyndromic High Myopia Associated with Recessive Mutations in LRPAP1

Purpose: To describe a new form of childhood-onset rhegmatogenous retinal detachment (RRD) in autosomal recessive high myopia associated with mutations in LRPAP1. Design: Retrospective cohort study. Participants: A total of 12 children (24 eyes) with recessive LRPAP1 mutations and associated high myopia. Methods: Serial ophthalmological examination and retinal imaging during 4.6±1.9 (mean ± standa

A simple correction for the parallax effect in X-ray pair distribution function measurements

Total scattering and pair distribution function (PDF) analysis has created new insights that traditional powder diffraction methods have been unable to achieve in understanding the local structures of materials exhibiting disorder or complex nanostructures. Care must be taken in such analyses as subtle and discrete features in the PDF can easily be artefacts generated in the measurement process, w

EV powertrain topologies for electric road applications

Electric road systems (ERS) are technologies that allow to charge electric vehicles (EVs) while they are driving. A large scale implementation of ERS would allow to significantly reduce the installed battery capacity on board the vehicles, which consequently reduces their weight and cost. Due to geographical, practical and economic constraints the ERS is not expected to cover the full extension of

Influence of Leptin and Adiponectin Supplementation on Intraepithelial Lymphocyte and Microbiota Composition in Suckling Rats

Dietary components in early life play a role in both microbiota and intestinal immune system maturation in mammalian species. Adipokines, as endogenously produced hormones from breast milk, may have an impact on this process. The aim of the present study was to establish the influence of leptin and adiponectin supplementation during suckling on the intraepithelial lymphocyte composition, intestina

A Collaborative Survey of 80 Mutations in the BRCA1 Breast and Ovarian Cancer Susceptibility Gene : Implications for Presymptomatic Testing and Screening

OBJECTIVES:To report the initial experience of an international group of investigators in identifying mutations in the BRCA1 breast and ovarian cancer susceptibility gene, to assess the spectrum of such mutations in samples from patients with different family histories of cancer, and to determine the frequency of recurrent mutations.DESIGN:Nine laboratories in North America and the United Kingdom

Did the Computer Revolution shift the fortunes of U.S. cities? Technology shocks and the geography of new jobs

This paper shows how the Computer Revolution of the 1980s shifted the economic trajectories of U.S. cities. Examining the emergence of new occupational titles in official census classifications, we document a sharp reversal in the skill content of new jobs. While technological change was biased towards routine skills throughout the 1970s, new job titles mainly appeared in occupations and industrie

Industrial renewal in the 21st century: evidence from US cities

Industrial renewal in the 21st century: evidence from US cities. Regional Studies. Where and why do new industries emerge? Using revisions of official industrial classifications, this paper documents the appearance of new industries in the US economy between 2000 and 2010 stemming directly from technological advances. Examining differences in new industry creation across cities, this paper shows t

Patents and corporate credit risk

A vast literature documents a positive relationship between patents and companies stock market performance. Nevertheless, evidence on the influence of patents on companies’ debt capacity remains sparse. In this article, we examine the relationship between companies’ patent portfolios and their credit rating, providing relevant, albeit indirect, evidence on patents as a debt funding mechanism. Usin

Uber Happy? Work and Well-being in the “Gig Economy”

We study the rise of the so-called “gig economy” through the lens of Uber and its drivers in the United Kingdom. Using administrative data from Uber and a new representative survey of London drivers, we explore their backgrounds, earnings, and subjective well-being. We find that the vast majority of Uber drivers are male immigrants, primarily drawn from the bottom half of the London income distrib
