Soil respiration under different N fertilization and irrigation regimes in Bengaluru, S-India
(2023-09-15)
Rapid urbanization in many countries of the Global South has led to intensification of urban and peri-urban agriculture (UPA) whose effects on the soils’ physical, chemical, and microbial properties have been hardly studied. We therefore investigated the effects of different intensity levels, exemplified by three rates of mineral nitrogen (N) addition and irrigation on CO₂ emissions in typical crops during the wet (Kharif) and dry (Rabi) season on a Nitisol in Bengaluru, S-India. Respiration data were collected from ...

Promoting pre-service teachers’ professionalism in steam education and education for sustainable development through mathematical modelling activities
(2023-06-19)
To successfully solve the complex challenges facing us in the 21st century, people with expertise in the science, technology, engineering, arts and mathematics (STEAM) fields and other fields are needed, especially for their interdisciplinary way of thinking and working. These competencies should be learned in school, which first implies teacher education to that effect. In this article, a detailed theoretical reflection on the connections or overlapping areas between STEAM education and the dimension of sustainability ...

FEM–CM as a hybrid approach for multiscale modeling and simulation of ferroelectric boundary value problems
(2023-06-05)
Constitutive modeling of ferroelectrics is a challenging task, spanning physical processes on different scales from unit cell switching and domain wall motion to polycrystalline behavior. The condensed method (CM) is a semi-analytical approach, which has been efficiently applied to various problems in this context, ranging from self-heating and damage evolution to energy harvesting. Engineering applications, however, inevitably require the solution of arbitrary boundary value problems, including the complex multiphysical ...

Narratives of land abandonment in a biocultural landscape of Spain
(2023-10-31)
Rural abandonment is a significant process in the Mediterranean region, posing sustainability challenges for rural and urban areas. Although there is an increase in studies focusing on the ecological implications and impacts of land abandonment and the role of rewilding, there is a knowledge gap in the study of the socio-cultural dimension of abandonment from the local perspective, even though it is crucial for land management decision. This study focuses on a case study in Western Spain, where a social survey was ...

Disentangling the practice of landscape approaches: a Q-method analysis on experiences in socio-ecological production landscapes and seascapes
(2023-03-23)
Landscape approaches are gaining momentum in both scientific and policy agendas. However, landscape approaches comprise a multitude of concepts, approaches and principles, which are in part similar, in some parts different or even contradictory. In this paper, we used a Q-method questionnaire to explore how landscape approaches are understood and employed in 45 case studies of socio-ecological production landscapes and seascapes derived from the International Partnership for the Satoyama Initiative (IPSI), as well ...

The correlation between honesty-humility and attitude toward counterfeit luxury
(2023-10-18)
This research focuses on the relation between Honesty-Humility and attitude toward counterfeit luxury. Honesty-Humility is defined as the tendency to be fair in dealing with others. Given that the act of knowingly purchasing a counterfeit could be judged as morally questionable, immodest, and manipulative, we predicted that people lower in Honesty-Humility would report more positive attitudes toward counterfeit luxury. Given that related research from behavioral research revealed Honesty-Humility to be the key predictor ...

ESG criteria and the credit risk of corporate bond portfolios
(2023-10-25)
Demand for sustainable fixed-income investment solutions is surging but there is hardly research on the impact of sustainability on the risk characteristics of fixed-income portfolios. This study examines the impact of sustainability on the credit risk exposure of corporate bond portfolios between 2013 and 2020 by analyzing the returns of sustainable and non-sustainable portfolios using two different asset pricing models and environmental, social, and governance (ESG) ratings from different providers. Controlling for ...

Portfolio benefits of taxonomy orientated and renewable European electric utilities
(2023-08-19)
This paper investigates carbon and energy mix risk in the equity prices of EU-Taxonomy orientated and renewable European electric utility companies. We calculate carbon intensity and energy mix factors to measure possible carbon and energy mix premia while investigating the performance of portfolios of EU-Taxonomy orientated and renewable European electric utilities. We use a unique dataset to extend the three-factor model presented by Fama and French (1993) and find evidence of a positive renewable energy mix premium ...

DPH1 Gene Mutations Identify a Candidate SAM Pocket in Radical Enzyme Dph1 Dph2 for Diphthamide Synthesis on EF2
(2023-11-16)
In eukaryotes, the Dph1•Dph2 dimer is a non-canonical radical SAM enzyme. Using iron-sulfur (FeS) clusters, it cleaves the cosubstrate S-adenosyl-methionine (SAM) to form a 3-amino-3-carboxy-propyl (ACP) radical for the synthesis of diphthamide. The latter decorates a histidine residue on elongation factor 2 (EF2) conserved from archaea to yeast and humans and is important for accurate mRNA translation and protein synthesis. Guided by evidence from archaeal orthologues, we searched for a putative SAM-binding pocket ...

Telecoupled urban demand from West African cities causes social-ecological land use transformation in Saharan oases
(2023-09-08)
Little is known about the long-distance telecoupling effects of urban food demands on land use changes (LUCs) in remote oases of the Southern Sahara. Using the example of two typical oasis settlements on Mont Bagzam in the southern Ar Mountains of Niger which are linked to regional and global markets by an unpaved road since 2015, this study aimed at analyzing time trajectories of LUCs and related changing agricultural production patterns. LUCs were quantified for 1955 to 2022 using GIS-based mapping of agriculture ...
