Are Si-C bonds cleaved by microorganisms? A critical review on biodegradation of methylsiloxanes.

Chemosphere

April 2023

Institute for Sustainable Chemistry, Leuphana University Lüneburg, Universitätsallee 1, D-21335, Lüneburg, Germany.

Methylsiloxanes, compounds that contain HC-Si-O subunits in their molecular structure, are emerging ubiquitous pollutants now detected in many environmental compartments. These compounds and generally Si-C bonds do not occur in living nature, but are industrially produced worldwide in millions of tons per annum and are widely used, resulting in their release to the environment. It is an open question whether or to what extent microorganisms are able to decompose these compounds.

Previous research found that experimentally reducing people's belief in free will affects social behaviors. However, more recent investigations could not replicate several findings in this literature. An explanation for the mixed findings is that free will beliefs are related to social behaviors on a correlational level, but experimental manipulations are not able to detect this relation.

Intensification of land use by humans has led to a homogenization of landscapes and decreasing resilience of ecosystems globally due to a loss of biodiversity, including the majority of forests. Biodiversity-ecosystem functioning (BEF) research has provided compelling evidence for a positive effect of biodiversity on ecosystem functions and services at the local (α-diversity) scale, but we largely lack empirical evidence on how the loss of between-patch β-diversity affects biodiversity and multifunctionality at the landscape scale (γ-diversity). Here, we present a novel concept and experimental framework for elucidating BEF patterns at α-, β-, and γ-scales in real landscapes at a forest management-relevant scale.

Unlabelled: Why do some international organizations (IO) accrete delegated authority over time while in others delegation is static or declines? We hypothesize that the dynamics of delegation are shaped by an IO's founding contract. IOs rooted in an open-ended contract have the capacity to discover cooperation over time: as new problems arise these IOs can adopt new policies or strengthen collaboration in existing areas. This, in turn, triggers a demand for delegation.

We investigate whether communication strategies that portray climate change as a nonlinear phenomenon provoke increases in laypeople's climate change risk perceptions. In a high-powered, preregistered online experiment, participants were exposed to linear or nonlinear predictions of future temperature increases that would be expected if global greenhouse gas emissions were not reduced. We hypothesized that the type of climate change portrayal would impact perceptions of qualitative risk characteristics (catastrophic potential, controllability of consequences) which would, in turn, affect laypeople's holistic risk perceptions.

Reading is a complex cognitive task with the ultimate goal of comprehending the written input. For longer, connected text, readers generate a mental representation that serves as its basis. Due to limited cognitive resources, common models of discourse representation assume distinct processing levels, each relying on different processing mechanisms.

Many occupational settings require individuals to make important decisions immediately after awakening. Although a plethora of psychological research has separately examined both sleep and anchoring effects on decision-making, little is known about their interaction. In the present study, we seek to shed light on the link between sleep inertia, the performance impairment immediately after awakening, and individuals' susceptibility to the anchoring bias.

Quantum chemical calculation of the vapor pressure of volatile and semi volatile organic compounds.

Environ Sci Process Impacts

November 2022

Institute of Sustainable and Environmental Chemistry, Leuphana University Lüneburg, 21335 Lüneburg, Germany.

The vapor pressure is a specific and temperature-dependent parameter that describes the volatility of a substance and thus its driving force for evaporation or sublimation into the gas phase. Depending on the magnitude of the vapor pressure, there are different methods for experimental determination. However, these are usually associated with a corresponding amount of effort and become less accurate as the vapor pressure decreases.

Across the globe, men make markedly more money than women, even within the same position. We introduce egalitarian norm messaging as a potential intervention to increase women's salaries and counter the gender pay gap. In two preregistered experiments with seasoned professionals ( = 435, work experience: > 8 years, salary negotiations: > 18 per year), we find a significant gender pay bias-Human Resources (HR) experts offered markedly lower salaries in an online negotiation to (simulated) female versus male candidates with identical qualifications.

Antibiotics are detected worldwide in the aquatic environment, with continuously rising concentrations. Antibiotics in the environment have the potential to damage ecosystems and contribute to the development of resistance. Whilst a few antibiotics, such as some β-lactams, are eliminated by effluent treatment, others, such as fluoroquinolones, are not or just partially removed and enter the environment.

Do people learn from failure or do they mentally "tune-out" upon failure feedback, which in turn undermines learning? Recent research (Eskreis-Winkler & Fishbach, 2019) has suggested the latter, whereas research in educational and work settings indicates that failure can lead to more learning than can success and error-free performance. We conducted two preregistered experiments to replicate the tune-out effect and to test two potential boundary conditions (N = 520). The tune-out effect fully replicated in those experimental conditions that represented close replications of the original study, underscoring the reliability of the original effect.

Teacher Trainees' Well-Being-The Role of Personal Resources.

Int J Environ Res Public Health

July 2022

Department of Educational Research and Educational Psychology, IPN-Leibniz Institute for Science and Mathematics Education, Olshausenstraße 62, 24118 Kiel, Germany.

Teacher well-being is intrinsically associated with their personal resources, including health literacy and occupational self-regulation. However, there are few empirical findings on teacher trainees' health literacy. Furthermore, occupational self-regulation has so far only been associated with indicators of occupational well-being.

Children with an advanced knowledge of emotions are generally more socially competent, less likely to suffer from psychopathology, and more likely to succeed in school, both socially and academically. The assessment of children's emotion knowledge has thus gained importance in recent decades - both in psychiatric practice and in developmental and educational psychology. However, there is still a lack of appropriate instruments for assessing children's emotion knowledge in a performance test reliably, and for a broad age range.

Repurposing chemical waste: Sustainable chemistry for circularity beyond artificial intelligence.

Cell

July 2022

Institute of Sustainable Chemistry, Leuphana University Lüneburg, Lüneburg, Germany; Research and Education Hub, International Sustainable Chemistry Collaborative Centre ISC3, Bonn, Germany. Electronic address:

Generating considerable amounts of industrial waste requires rethinking chemistry for circularity in a broader picture. We discuss the study by Wołos et al. (2022) showing that the critical application of artificial intelligence on chemical reactivity can help us trace an unprecedented number of syntheses to novel responsible uses of waste.

The production of biodegradable polymers as coproducts of other commercially relevant plant components can be a sustainable strategy to decrease the carbon footprint and increase the commercial value of a plant. The biodegradable polymer cyanophycin granular polypeptide (CGP) was expressed in the leaves of a commercial tobacco variety, whose seeds can serve as a source for biofuel and feed. In T0 generation in the greenhouse, up to 11% of the leaf dry weight corresponded to the CGP.

Today, industrial-scale mining is a high-tech activity that transforms places and regions by creating massive technological infrastructures. "The public" and its relationship with this industry are seen as increasingly relevant for mining projects; however, the role technologies play in this regard is as yet under-researched. In this article, we use an example from the European Union's Horizon 2020 research program to examine how technoscientific actors build relationships with the public in the context of mining technology development.

Restoration ecology commonly seeks to re-establish species of interest in degraded habitats. Despite a rich understanding of how succession influences re-establishment, there are several outstanding questions that remain unaddressed: are short-term abundances sufficient to determine long-term re-establishment success, and what factors contribute to unpredictable restorations outcomes? In other words, when restoration fails, is it because the restored habitat is substandard, because of strong competition with invasive species, or alternatively due to changing environmental conditions that would equally impact established populations? Here, we re-purpose tools developed from modern coexistence theory to address these questions, and apply them to an effort to restore the endangered Contra Costa goldfields (Lasthenia conjugens) in constructed ("restored") California vernal pools. Using 16 years of data, we construct a population model of L.

Background: Workplace-related stress is a major risk factor for mental and physical health problems and related sickness absence and productivity loss. Despite evidence regarding the effectiveness of different workplace-based interventions, the implementation of stress prevention interventions is rare, especially in micro and small-sized enterprises (MSE) with fewer than 50 employees. The joint research project "PragmatiKK" aims to identify and address the specific barriers to the implementation of stress prevention interventions in MSE.
