Photoelectron circular dichroism of a model chiral anion
(2022-01-18)
Photoelectron circular dichroism (PECD) in the one-photon detachment of a model chiral anionic system is studied theoretically by the single center method. The computed chiral asymmetry, characterized by the dichroic parameter β1 of up to about ±3%, is in good accord with the first experimental observations of the effect in photodetachment of amino acid anions [P. Krüger and K. M. Weitzel, Angew. Chem., Int. Ed. 60, 17861 (2021)]. Our findings confirm a general assumption that the magnitude of PECD is governed by the ...

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 ...

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 ...

Interrupting the neoliberal masculine state machinery? Strategic selectivities and municipalist practice in Barcelona and Zagreb
(2022-07-07)
All municipalist initiatives are confronted with what Marx called the ‘state machinery’: an ensemble of apparatuses protecting the status quo of capitalist accumulation. It is difficult for municipalist movements to sustain their momentum of storming the city halls in the face of this reality. Looking at Barcelona En Comú (Barcelona in Common) and Zagreb Je NAŠ! (Zagreb Is Ours!), the article discusses what experiences municipalist actors gain when inspecting the state machinery close up. We identify the traces they ...

Challenges in detecting proximal effects of existential threat on lie detection accuracy
(2022-06-14)
The present work documents our investigation of proximal (i.e., immediate) effects of existential threat on the process of lie detection. Specifically, we hypothesized that lie detection accuracy will be higher in a mortality salience (MS) condition compared with the control condition. In two lab-based studies (N = 120; N = 109) and one internet study (N = 1294), we did not find any evidence for this hypothesis, that is, MS effects on lie detection accuracy were constantly not significant. However, these null findings ...

Development and Validation of a German Interpersonal Sensitivities Circumplex (ISC-G)
(2022-11-09)
The Interpersonal Sensitivities Circumplex (ISC) assesses individual differences in sensitivities to aversive interpersonal behaviors. In this research (total N = 1,519), we developed and validated a German adaptation of the ISC (ISC-G) and extended the nomological net of interpersonal sensitivity as a construct. Using the structural summary method, we investigated associations with self- and informant reports of adaptive (interpersonal) personality traits as well as self-reported personality functioning, maladaptive ...

Microstructural and mechanical properties of AlSi10Mg: Hybrid welding of additively manufactured and cast parts
(2022-12-07)
Welding and joining of hybrid components consisting of additively manufactured (AM) parts and conventionally processed parts offer new opportunities in structural design. In the present study, AlSi10Mg specimens were fabricated using two different manufacturing processes, i.e., laser-based powder-bed fusion of metals (PBF-LB/M) and casting, and welded by means of friction stir welding (FSW). Material strength of dissimilar welded joints was found to be governed by the as-cast material, which is characterized by a ...

Additive Manufacturing of Binary Ni–Ti Shape Memory Alloys Using Electron Beam Powder Bed Fusion: Functional Reversibility Through Minor Alloy Modification and Carbide Formation
(2022-11-30)
Shape memory alloys (SMAs), such as Ni–Ti, are promising candidates for actuation and damping applications. Although processing of Ni–Ti bulk materials is challenging, well-established processing routes (i.e. casting, forging, wire drawing, laser cutting) enabled application in several niche applications, e.g. in the medical sector. Additive manufacturing, also referred to as 4D-printing in this case, is known to be highly interesting for the fabrication of SMAs in order to produce near-net-shaped actuators and ...

Electrochemical polarization behavior and superelastic properties of a Fe–Mn–Al–Ni–Cr shape memory alloy
(2022-10-22)
The present study investigates the corrosion behavior of a Fe–Mn–Al–Ni–Cr shape memory alloy in a 5.0 wt% NaCl solution in combination with the functional properties. In a single crystalline condition, the investigated alloy shows a superior superelastic response with a maximum recovery strain of 5.2%. Furthermore, the results of the potentiodynamic polarization and impedance spectroscopy show that the addition of chromium generally improves corrosion resistance by increasing the resistance to localized corrosion. ...

[Rezension zu:] Veronika Settele 2020: Revolution im Stall. Landwirtschaftliche Tierhaltung in Deutschland und Paul R. Josephson 2020: Chicken. A History from Farmyard to Factory
(2022-08-25)
Landwirtschaftlich genutzte Tiere spielten in der geschichtswissenschaftlichen Forschung bisher meist eine Nebenrolle. Sie traten vor allem als Wirtschaftsobjekte in der Agrargeschichte in Erscheinung, oder ihr Verschwinden aus dem öffentlichen Raum diente der Tiergeschichte als Indikator für den Übergang in die Moderne. In jüngerer Zeit aber rücken die landwirtschaftlichen Tiere immer öfter in den direkten Fokus der historischen Forschung – eine begrüßenswerte Entwicklung gerade vor dem Hintergrund aktueller Debatten ...
