Exclusive measurement of quasi-free η-photoproduction from deuterium
2003
Quasi-free photoproduction of eta-mesons from the deuteron has been measured at the tagged photon facility of the Mainz microtron MAMI with the photon spectrometer TAPS for incident photon energies from the production threshold at 630 MeV up to 820 MeV. In a fully exclusive measurement eta-mesons and recoil nucleons were detected in coincidence. At incident photon energies above the production threshold on the free nucleon, where final state interaction effects are negligible, an almost constant ratio of sigma(n)/sigma(p)=0.66+/-0.10 was found. At lower incident photon energies the ratio rises due to re-scattering effects. The average ratio agrees with the value extracted from a comparison …

An Internet-delivered Cognitive-Behavioral Therapy (iCBT) for Prolonged Grief Disorder (PGD) in adults: A multiple-baseline single-case experimental …
2022
The death of a loved one has physical, psychological, and social consequences. Between 9.8 and 21.5 % of people who lose a loved one develop Prolonged Grief Disorder (PGD). Internet- and computer-based interventions (i.e., Internet-delivered Cognitive-Behavioral Therapy, iCBT) are cost-effective and scalable alternatives that make it possible to reach more people with PGD. The main goal of the present investigation was to examine the effect and feasibility (usability and satisfaction) of an iCBT (GROw program) for adults with PGD. A secondary objective was to detect adherence to the app (Emotional Monitor) used to measure daily grief symptoms. The study had a singlecase multiple-baseline AB…
A Bayesian stable isotope mixing model for coping with multiple isotopes, multiple trophic steps and small sample sizes
2022
We introduce a Bayesian stable isotope mixing model for estimating the relative contributions of different dietary components to the tissues of consumers within food webs. The model is implemented with the probabilistic programming language Stan. The model incorporates isotopes of multiple elements (e.g. C, N, H) for two trophic levels, when the structure of the food web is known. In addition, the model allows inclusion of latent trophic levels (i.e. for which no empirical data are available) intermediate between sources and measured consumers. Running the model in simulations driven by a real dataset from Finnish lakes, we tested the sensitivity of the posterior distributions by altering c…
How paradoxical is ‘paradoxical’ outcome? : Different pathways and implications
2021
The present special issue includes single and multiple case studies which report on the phenomenon of ‘paradoxical’ outcomes in psychotherapy, operationalized as discordant outcome assessments within the same case. In an attempt to find ground for my published response, I endeavored to juxtaposition the cases from the different studies, and by doing that gain an overview of the contributions and arguments. As a result of that exercise, I suggest three different types of paradoxical outcome with different pathways and implications. Discussing the concept of ‘illusory mental health’ as a possible explanation for paradoxical outcome, I suggest that self-ratings within a nonclinical range, give…
Akceptacja choroby jako mediator zależności pomiędzy niepełnosprawnością neurologiczną a jakością życia uwarunkowaną stanem zdrowia osób ze stwardnie…
2020
Stwardnienie rozsiane (sclerosis multiplex – SM) jest postępującą demielinizacyjną chorobą ośrodkowego układu nerwowego, która może prowadzić do trwałej niepełnosprawności. Z tego względu stanowi wyzwanie dla procesu adaptacji psychicznej i może prowadzić do obniżenia jakości życia. Celem pracy było określenie relacji pomiędzy niepełnosprawnością neurologiczną występującą w przebiegu SM, przystosowaniem do choroby wyrażonym przez stopień jej akceptacji oraz jakością życia uwarunkowaną stanem zdrowia. Materiał i metody: W badaniu wzięło udział 137 osób ze zdiagnozowanym SM. W badaniach wykorzystano Skalę niepełnosprawności neurologicznej szpitala Guy, Skalę akceptacji choroby oraz Skalę wpły…
Niepełnosprawność a jakość życia pacjentów ze stwardnieniem rozsianym : mediacyjna rola zapotrzebowania na wsparcie społeczne
2019
Multiple sclerosis (MS) is a progressive neurological disease that leads to significant disability and can affect health related quality of life. Social support may be one of the predictors of quality of life in MS. The aim of this study was to determine the relationship between disability associated with the course of multiple sclerosis, social support and quality of life. 137 people diagnosed with MS participated in the study. Extended Disability Status Scale (EDSS), Guy's Neurological Disability Scale (GNDS), Berlin Social Support Scales and the Multiple Sclerosis Impact Scale 29 (MSIS-29) were used in the study. The study showed no significant relationship between disability and perceiv…
Towards explainable interactive multiobjective optimization : R-XIMO
2022
AbstractIn interactive multiobjective optimization methods, the preferences of a decision maker are incorporated in a solution process to find solutions of interest for problems with multiple conflicting objectives. Since multiple solutions exist for these problems with various trade-offs, preferences are crucial to identify the best solution(s). However, it is not necessarily clear to the decision maker how the preferences lead to particular solutions and, by introducing explanations to interactive multiobjective optimization methods, we promote a novel paradigm of explainable interactive multiobjective optimization. As a proof of concept, we introduce a new method, R-XIMO, which provides …
Environmental context determines pollution impacts on ecosystem functioning
2023
Global change assessments have typically ignored synthetic chemical pollution, despite the rapid increase of pharmaceuticals, pesticides and industrial chemicals in the environment. Part of the problem reflects the multifarious origins of these micropollutants, which can derive from urban and agricultural sources. Understanding how micropollutants harm ecosystems is a major scientific challenge due to asymmetries of stress across trophic levels and ecological surprises generated by multiple drivers interacting in human-impacted landscapes. We used field assays above and below municipal wastewater treatment plants (WWTPs) in 60 sampling locations across 20 Swiss streams to test how micropoll…
Multiple-batch spawning: a risk-spreading strategy disarmed by highly intensive size-selective fishing rate
2022
Can the advantage of risk-managing life-history strategies become a disadvantage under human-induced evolution? Organisms have adapted to the variability and uncertainty of environmental conditions with a vast diversity of life-history strategies. One such evolved strategy is multiple-batch spawning, a spawning strategy common to long-lived fishes that ‘hedge their bets' by distributing the risk to their offspring on a temporal and spatial scale. The fitness benefits of this spawning strategy increase with female body size, the very trait that size-selective fishing targets. By applying an empirically and theoretically motivated eco-evolutionary mechanistic model that was parameterized for …
