The Road to Hell Is Paved With Good Intentions: How Common Practices in Scale Construction Hurt Validity
(2022-09-29)
Sound scale construction is pivotal to the measurement of psychological constructs. Common item sampling procedures emphasize aspects of reliability to the disadvantage of aspects of validity, which are less tangible. We use a health knowledge test as an example to demonstrate how item sampling strategies that focus on either factor saturation or construct coverage influence scale composition and demonstrate how to find a trade-off between these two opposing needs. More specifically, we compile three 75-item health ...

Wer leidet in der Sozialen Arbeit an Erschöpfung? Ergebnisse einer Repräsentativerhebung
(2023-06-05)
Nach der internationalen Studienlage weisen Sozialarbeitende ein hohes berufsspezifisches Risiko für die Entwicklung von Disstress, Erschöpfung und Burnout auf. Gemäß dem Modell der Arbeitsanforderungen und -ressourcen (JD-R) führen hohe oder schlechte Arbeitsanforderungen zu Erschöpfung. In Deutschland besteht ein Forschungsdefizit zur Gesundheit von Sozialarbeitenden. Ziel der Untersuchung ist es, innerhalb der Sozialen Arbeit gefährdete Personengruppen unter Berücksichtigung von berufsspezifischen Einflussfaktoren ...

Determinants of success and constraints of integrated ridesharing in rural areas
(2021-09-01)
Ridesharing is often seen as a possibility to increase the mobility of citizens in rural areas, especially in connection with existing public transport. Two platforms were examined and evaluated in the research project “GetMobil”, which focuses on the barriers and potentials in relation to the effects achieved. This was done with several surveys, analysis of usage data and expert interviews. The research showed that one common feature of both platforms was the low number of successfully completed rides. The question ...

Optimised use of data fusion and memory-based learning with an Austrian soil library for predictions with infrared data
(2023-06-24)
Infrared spectroscopy in the visible to near-infrared (vis–NIR) and mid-infrared (MIR) regions is a well-established approach for the prediction of soil properties. Different data fusion and training approaches exist, and the optimal procedures are yet undefined and may depend on the heterogeneity present in the set and on the considered scale. The objectives were to test the usefulness of partial least squares regressions (PLSRs) for soil organic carbon (SOC), total carbon (Ct), total nitrogen (Nt) and pH using ...

A novel cubic-exp evaluation algorithm considering non-symmetrical axial response signals of confocal microscopes
(2023-06-26)
The depth discrimination in confocal microscopy is based on the digital analysis of depth response signals obtained by each camera pixel during measurement. Various signal-processing algorithms are used for this purpose. The accuracy of these algorithms is inter alia restricted by the axial symmetry of the signals. However, in practice response signals are rather asymmetrical especially in case of measurement objects with critical surface structures such as edges or steep flanks. We present a novel signal-processing ...

Sonication-assisted liquid exfoliation and size-dependent properties of magnetic two-dimensional α-RuCl₃
(2023-04-26)
Originating from the hexagonal arrangement of magnetic ions in the presence of strong spin orbit coupling, α-RuCl₃ is considered as model system for the Kitaev-Heisenberg model. While the magnetic properties of α-RuCl₃ have been studied in bulk single crystals or micromechanically-exfoliated nanosheets, little is known about the nanosheets' properties after exfoliation by techniques suitable for mass production such as liquid phase exfoliation (LPE). Here, we demonstrate sonication-assisted LPE on α-RuCl₃ single ...

Integrative-interpersonal dynamic therapy for poststroke depression (INID): study protocol of a randomised controlled pilot trial
(2023-08-08)
Introduction Depression is the most frequent psychiatric disorder following stroke, affecting about one-third of stroke survivors. Patients experience poorer recovery, lower quality of life and higher mortality compared with stroke survivors without depression. Despite these well-known malign consequences, poststroke depression (PSD) is regarded underdiagnosed and undertreated. Evidence of beneficial effects of psychotherapy to treat PSD remains scarce and inconclusive and is limited by heterogeneity in design, content ...

Evaluating the role of maladaptive personality traits in schema therapy and cognitive behavioural therapy for depression
(2022-05-10)
Background: Advancements in the treatment of depression are pivotal due to high levels of non-response and relapse. This study evaluated the role of personality pathology in the treatment of depression by testing whether maladaptive personality traits (1) predict changes in depression over treatment or vice versa, (2) change themselves over treatment, (3) change differentially depending on treatment with schema therapy (ST) or cognitive behavioural therapy (CBT), and (4) moderate the effectiveness of these ...

Extreme droughts in oligotrophic mountain grasslands cause substantial species abundance changes and amplify community filtering
(2021-10-08)
Questions
Mountain grasslands can be strongly affected by extreme droughts such as those related to climate change. What are the impacts of extreme droughts on community composition, diversity, Ellenberg indicator scores and species groups in oligotrophic montane Nardus grasslands, and what are the associated mechanisms of vegetation change?
Location
Rhön Mountains, Germany.
Methods
Over three consecutive years, we investigated the effects of yearly droughts (April–August) in an experimental setup with rainout ...

Vibrationally Resolved Absorption and Fluorescence Cross Sections of Adamantane in the Far-ultraviolet Spectral Range on an Absolute Scale
(2023-07-20)
High-resolution absorption, dispersed fluorescence emission, and photoionization cross sections are presented for gas-phase adamantane excited by synchrotron radiation in the exciting-photon energy range of 6–30 eV. Relative and absolute absorption cross sections of so-far unmatched resolution of down to 0.27 cm−¹ line width in the region from 6.4–28 eV are shown along with newly discovered vibronic substructures around the HOMO–LUMO transition. Absorption line positions are provided with very high accuracy and listed ...
