This paper focuses on the efficiency evaluation of bike-sharing systems (BSSs) and develops an approach based on data envelopment analysis (DEA) to support the decisions regarding the performance evaluation of BSS stations. The proposed methodology is applied and tested for the Malmöbybike BSS in Malmö, Sweden. This was done by employing spatial analyses and data about the BSS usage trends as well

Background aims: Cell-based therapies of pulmonary diseases with mesenchymal stromal cells (MSCs) are increasingly under experimental investigation. In most of these, MSCs are administered intravenously or by direct intratracheal instillation. A parallel approach is to administer the cells into the lung by endoscopic atomization (spraying). In a previous study, the authors developed a flexible end

This paper investigates how the characteristics of university laboratories influence the propensity of Ph.D. students to entrepreneurship, and thus, contribute to the transfer of academic knowledge to society. As determinants of Ph.D. entrepreneurship, we focus on the lab scientific and social capital as well as on the business experience that Ph.D. students acquire during their training period. T

Scholarly and practitioner interest in the topic of authentic leadership has grown dramatically over the past two decades. Running parallel to this interest, however, have been a number of concerns regarding the conceptual and methodological underpinnings for research on the construct. In this exchange of letters, the cases for and against the current authentic leadership theory are made. Through

Background: In a previous cohort study of 4-year-old Danish children, revaccination with the live measles-mumps-rubella vaccine (MMR) was associated with a 16% reduction in the rate of hospitalization lasting two days or longer for non-measles-mumps-rubella infections. Aim: To examine if the introduction of revaccination with MMR at 4 years of age in Denmark (spring 2008) and at 7–9 years of age i

With increasing mobility of people across the world, there is a pressing need to develop evidence-based teaching practices that lead to high-quality education, which serves the needs of inclusive societies and social and epistemic justice. This book presents cutting-edge qualitative case-study research across a range of educational contexts, research-method contributions and theory-oriented chapte

BACKGROUND: Small intestinal neuroendocrine tumors (SI-NETs) are difficult to diagnose in the early stage of disease. Current blood biomarkers such as chromogranin A (CgA) and 5-hydroxyindolacetic acid (5-HIAA) have low sensitivity and specificity. This is a first pre-planned interim analysis (NORDIC non-interventional, exploratory, EXPLAIN study (NCT02630654)). Its objective is to investigate if

Purpose of Review: The Arctic has experienced the most rapid change in climate of anywhere on Earth, and these changes are certain to drive changes in the carbon budget of the Arctic as vegetation changes, soils warm, fires become more frequent, and wetlands evolve as permafrost thaws. In this study, we review the extensive evidence for Arctic climate change and effects on the carbon cycle. In add

Total-body irradiation (TBI) followed by transfer of bone marrow cells from donors is routinely performed in immunology research and can be used to manipulate differentiation and/or function of bone cells. However, exposure to high-dose radiation can result in irreversible osteopenia, and transfer of heterogeneous cell populations can complicate interpretation of results. The goal of this research

Spaceflight results in reduced bone accrual and muscle atrophy in growing rodents. Some studies suggest that the detrimental effects of spaceflight are due, in part, to impaired growth hormone (GH) signaling. An experiment flown aboard STS-41 (October 6–10, 1990) evaluated the efficacy of recombinant human growth hormone (rhGH) in ameliorating the detrimental effects of spaceflight on the musculos

This article describes and analyses social structure, poverty, wealth, and economic inequality in Stockholm from 1650 to 1750. We begin by establishing the social structure, using census data and other sources. To study wealth and poverty, the main sources are a complete record of the wealth tax of 1715, comprising 17,782 taxpayers, and a total of 1,125 probate inventories sampled from the years 1

BACKGROUND: Central venous catheter (CVC) misplacement occurs frequently after right subclavian vein catheterization. It can be avoided by using ultrasound to confirm correct guidewire tip position in the lower superior vena cava prior to CVC insertion. However, retraction of the guidewire during the CVC insertion may dislocate the guidewire tip from its desired and confirmed position, thereby res
