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 ...

Das Inspection Panel der Weltbank. Entwicklungspolitische Praktiken zwischen Disruption und Legitimation
(Transcript, 2023)
Als zentrales Organ der Entwicklungspolitik kann die Weltbank viel über Inhalt und Form konkreter Maßnahmen bestimmen. Das Inspection Panel der Weltbank gilt in diesem Rahmen als Chance, Einfluss auf die Kreditvergabe zu nehmen und emanzipatorisches Potenzial zu entfalten. Dustin Schäfer lotet Möglichkeiten und Grenzen dieses Instruments aus und kombiniert dazu postkoloniale mit liberalen organisationssoziologischen Ansätzen. Aus der Perspektive einer machtkritischen Bürokratieforschung bietet er einerseits tiefgreifende ...

Kunst und Geld
(De Gruyter, 2023)
"Leiter setzte Geld in den Sand" titelte die Kasseler Lokalzeitung HNA im August 2017 und brachte geleakte Informationen aus dem Aufsichtsrat der documenta 14, einer weltweit renommierten Kunstausstellung, an die Öffentlichkeit: Die documenta gGmbH stehe kurz vor der Zahlungsunfähigkeit, ein Defizit von ca. 7 Millionen Euro wird erwartet. Dieses soll durch die teils öffentliche Finanzierung voraussichtlich mit Steuermitteln aufgefangen werden. Es beginnt eine breite Debatte in der sich Personen aus Politik, Kulturbetrieb ...

Domain Imaging in Periodic Submicron Wide Nanostructures by Digital Drift Correction in Kerr Microscopy
(2023-08-27)
Magneto-optical Kerr microscopy is a powerful method for imaging magnetic domains. Even though domain imaging below the diffractive resolution limit is possible, such investigations are getting increasingly complex with decreasing structure size due to the decreasing Kerr contrast. As magnetic domain images free of topographical artifacts are obtained by subtracting a reference image from the actual image, the corresponding challenges are additionally increased by unavoidable sample motion in the time interval between ...

Benzene Oxidation over Pt Loaded on Fly Ash Zeolite X
(2023-07-20)
In the present study, zeolite X (FANaX) was synthesized from coal fly ash (FA) by a two-step high-temperature method. In order to follow the effect of different contaminants in the starting coal ash, zeolite X was also synthesized from pure chemicals according to a classical recipe (NaX). Iron was loaded on this reference zeolite with the amount which was contained in the coal FA. The final catalytic samples were obtained by wet impregnation of Pt nanoparticles on both types of zeolite crystals. The most active samples ...
