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 ...

Showcasing the multifaceted aspects of agricultural transformation: The example of mountain oases in Oman
(2022-11-11)
In the Anthropocene the consequences of land-use transformation on ecosystem services are of growing concern, particularly in fragile areas of mountain agriculture that often represent high nature-value farmland. This study uses a decadal repeated survey approach to analyse the effects of modernisation on oasis systems in the Jabal Al Akhdar region of northern Oman. This rugged mountain region at the north-eastern tip of the Arabian Peninsula experiences a growing influx of regional and international tourists since ...

Bedeutende Städte jenseits der Metropolen? Regiopolen und ihre Rolle im deutschen Städtesystem
(2022-11-10)
Regiopolen und Regiopolregionen erfahren eine bisher kaum dagewesene Aufmerksamkeit in der deutschen Raumordnungspolitik. Neben der Förderung des deutschen RegioPole-Netzwerks durch den Bund sind Regiopolen und Regiopolregionen bereits in mehreren Raumordnungsplänen ausgewiesen. Im wissenschaftlichen Diskurs werden Regiopolen hingegen kaum aufgegriffen. Das zeigt sich insbesondere daran, dass zwar mit Dimensionen wie Stadtgröße (mehr als 100.000 Einwohner) und räumlicher Lage (außerhalb der Metropolregionen) operiert ...

Peanut monoculture-induced decline in fertility of Andosols in Nicaragua
(2022-08-23)
Background: Andosols are generally characterized by strong resilience to degradation and high soil fertility. This may decline during long-term peanut (Arachis hypogea) monoculture, as indicated by soil chemical and biological properties. Aims: The study investigated the monoculture-induced changes in soil chemical environment as driver for the decline in soil fertility. Methods: In this on-farm study, soils from seven sites cropped with peanut monoculture for different periods between 1 and 20 years were analyzed ...

Designing a Co-creation System for the Development of Work-process-related Learning Material in Manufacturing
(2022-01-12)
The increasing digitalization and automatization in the manufacturing industry as well as the need to learn on the job has reinforced the need for much more granular learning, which has not yet impacted the design of learning materials. In this regard, granular learning concepts require situated learning materials to support self-directed learning in the workplace in a targeted manner. Co-creation approaches offer promising opportunities to support employees in the independent design of such situated learning materials. ...

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 ...
