Chronic or recurrent pain is a common experience in children and adolescents. One questionnaire that is frequently used to assess pain-related disability is the Functional Disability Inventory (FDI). The aim of this study was to evaluate the psychometric properties of the Swedish version of the FDI. The patient group consisted of 30 patients, 8-17 years old. The comparison group consisted of 78 pu

In the Solar System, asteroids and Kuiper belt objects as well as comets are remnant planetesimals from the time of planet formation. Interactions between solids and gas inside a protoplanetary disc can, e.g. through the streaming instability, form gravitationally bound planetesimal-mass clouds of pebbles. Such clouds will inevitably have inelastic collisions between pebbles, lose energy and exper

Bildandet av planeter äger rum i skivor av gas, stoft och is runt nybildade stjärnor. Den här processen är inte helt förstådd men det första steget tros vara växten från mikrometer-stora stoftkorn till mm-cm-stora småstenar genom sammanväxande kollisioner. Vid de här storlekarna studsar stenarna eller går sönder snarare än fastnar i varandra när de kolliderar så tillväxten avstannar. Dessutom kännPlanets form in protoplanetary discs of gas, dust and ice around newborn stars. In the Solar System, not only planets are found as a result from the time of planet formation, but also remnant planetesimals in the form of asteroids, Kuiper belt objects and comets. Recent observations, e.g. by the space mission Rosetta, have found that comets are porous objects barely able to hold themselves togethe

The Mobile Cloud Network is an emerging cost and capacity heterogeneous distributed cloud topological paradigm that aims to remedy the application performance constraints imposed by centralised cloud infrastructures. A centralised cloud infrastructure and the adjoining Telecom network will struggle to accommodate the exploding amount of traffic generated by forthcoming highly interactive applicati

Antenna current optimization is often used to analyze the optimal perfor-mance of antennas. Antenna performance can be quantied in e.g., minimumQ-factor and maximal gain over Q-factor ratio. The performance of MIMOantennas is more involved and a single parameter is, in general, not sucientto quantify it. Here, the capacity of an idealized channel is used as the mainperformance quantity. An optimiz

This is a comment on Lofstedt and Bouder?s paper, which explores the prospects of evidence based uncertainty analysis in Europe, focusing on the ongoing development on uncertainty analysis at the European Food Safety Authority (EFSA). We very much welcome a discussion on the need to develop better treatment and communication of uncertainty in risk analysis, as we believe that such discussion is loThis is a comment on Lofstedt and Bouder’s paper, which explores the prospects of evidence based uncertainty analysis in Europe, focusing on the ongoing development on uncertainty analysis at the European Food Safety Authority (EFSA).

In the normal case, a reflexive pronoun is bound within its containing clause. More exceptionally, a reflexive is instead related to a binder in a higher clause – a phenomenon known as long distance binding. Long distance binding can be found in Norwegian, but as I will show here, with considerable variation between speakers. Quite a few speakers accept long distance binding only across indefinite

The pharmaceutical industry has experienced intermittent waves of mergers and acquisitions (M&As) since the 1980s and recently appeared to be in yet another wave. Previous studies indicated rather negative impacts of consolidation on research and development, suggesting that they do not necessarily lead to long-term reinforcement of research capabilities, although they may enrich the drug pipe

We identified six groups of diseases expected to cause serious future health issues on the basis of a WHO report. Approved drugs for these diseases were associated with 409 target proteins; however, the percentage of selected proteins with full-length structural information deposited in the Protein Data Bank (PDB) was only 9.8%. The reason for the low percentage may be as a result of a disproporti

This study examines the sharing of research tools among academic scientists in the life sciences and materials sciences in Japan. First, this study investigates material transfer, or the sharing of research tools, based on individual-level negotiation. Statistical analyses suggest that supplier-side scientists decide whether or not to fulfill requests for material transfer on the basis of: expecte

Drawing on a database of the competitive research funds in the Japanese academia, this study examines the distribution of research grants at the university and individual levels. The data indicates high inequality at the university level and slightly lower inequality at the individual level. Over the last three decades, the total grant budget has greatly increased and an increasing number of resea

Although the contribution of scientometric literature to policies on academic science has been substantial, the literature has focused primarily on the production of scientific knowledge, whereas limited attention has been paid to the other critical mission of academic institutions, i.e., education or the production of scientists. To address this limitation and better inform policymakers, the curr

This paper investigates the effect of international research visits on promotion. Research visits may help to expand existing networks and promote knowledge transfer while at the same time ensuring career stability, identified as the main barrier to mobility in Europe and Japan. Using a dataset of 370 bioscience professors in Japan we find that international research visits have a positive effect

Honesty in scientific publication is critical for scientific advancement, but dishonesty is commonly and increasingly observed in misconduct and other questionable practices. Focusing on dishonest conformity in peer review, in which authors unwillingly obey referees’ instructions in order to have their papers accepted even if the instructions contradict the authors’ scientific belief, the current

The modern science system relies on intense evaluation of scientific publication, in which scientific impact is highly emphasized, but its contribution to the progress of science has been controversial. Focusing on two aspects of the science system, resource allocation and academic career design, this study explores whether these policies, presumably aiming at high-impact research, actually achiev
