Housing Vacancy Outlined with Delphi Survey. Contributions of Participatory Research to a Just Transformation Process on Trial

Rising housing prices, associated supply gaps and displacement processes have revived the “housing issue” in Germany. This is particularly true for certain social groups socially marginalized by high competition in the housing market. The participatory action research study “Wohnungsleerstand wandeln!”(WohL) - “Worthy places from un-used spaces” examines the coexistence of housing scarcity and housing abundance in a district of the Munich metropolitan area. The goal is to use a participatory multi-method design, including a two-stage qualitative Delphi Survey, to find tailored solutions for the housing situation in each community. The Delphi method was used to reflect the diversity of perspectives in housing as well as the principles of participatory action research such as participation in research, proximity to the field, and capacity building through mutual learning. In the case of sustainable housing solutions, a group discussion process, in which facts are listed by participants (who remain anonymous) without taking into account local social structures, can lead to conclusions that are not accepted by the community. Hence, this paper explains how a Delphi Survey can be designed as a qualitative element of participatory action research. Therefore, the WohL Study and its qualitative Delphi Survey are presented, followed by a methodological reflection on the findings. It becomes clear that consensus and anonymity have to be balanced with solution sustainability. Criteria like the selection of participants, the process of group discussion as well as data collection and analysis have to be adapted to the specific field to be explored. New, diversity-sensitive and method-based approaches to decision making pave the way for a transformation of housing that must imply “vacancies” are to be (re)used, but also that collective decision-making brings “overlooked” groups “back into play.” Ultimately, the essential prerequisite for managing the transformation is the participation of the people of the community

Quantitative comparison of presumed-number-density and quadrature moment methods for the parameterisation of drop sedimentation

In numerical weather prediction models, parameterisations are used as an alternative to spectral modelling. One type of parameterisations are the so-called methods of moments. In the present study, two different methods of moments, a presumed-number-density-function method with finite upper integration limit and a quadrature method, are applied to a one-dimensional test case (‘rainshaft’) for drop sedimentation. The results are compared with those of a reference spectral model. An error norm is introduced, which is based on several characteristic properties of the drop ensemble relevant to the cloud microphysics context. This error norm makes it possible to carry out a quantitative comparison between the two methods. It turns out that the two moment methods presented constitute an improvement regarding two-moment presumed-number-density-function methods from literature for a variety of initial conditions. However, they are excelled by a traditional three-moment presumed-number-density-function method which requires less computational effort. Comparisons of error scores and moment profiles reveal that error scores alone should not be taken for a comparison of parameterisations, since moment profile characteristics can be lost in the integral value of the error norm

Soziale Diversität in angespannten Wohnungsmärkten? Wohnungsleerstand trifft Lebenswelt – partizipativ gewonnene Skizzen zu polarisierender Wohnraumnutzung

Die Wohnungsmärkte in Deutschland sind vielerorts angespannt. Besonders in Großstädten kann die Nachfrage nach Wohnraum seit Längerem nicht annähernd gedeckt werden (Henger et al. 2015). Die drängende Wohnraumversorgung in großen Städten fordert auch die umliegenden Kommunen heraus (Ehrhardt et al. 2022, S. 527). Auf dem Wohnungsmarkt geraten bestimmte Personengruppen je nach sozioökonomischem Status, sozialer Ähnlichkeit und gesellschaftlicher Erwünschtheit (Lukes et al. 2018) ins Hintertreffen. Der Wohnungsmarkt beeinflusst die soziale Komposition sowie die Funktionsfähigeit und Lebendigkeit der Kommunen als Gemeinwesen. In der Metropolregion München, konkret im Landkreis Dachau, beobachtet die partizipativ ausgerichtete Feldstudie „WohL – Wohnungsleerstand wandeln! Partizipative Entwicklung neuer Konzepte zum Umgang mit un(ter)genutztem Wohnraum“ diese Phänomene, deckt Hintergründe auf und skizziert Lösungsoptionen. Die WohL Delphi-Studie zeigt die Grenzen sozialer Diversität auf dem Wohnungsmarkt im Landkreis Dachau sowie  Impulse für die Förderung lebendiger und zukunftsfähiger Gemeinwesen auf. Demnach sind die aus der Literatur bekannten Listen der auf dem Wohnungsmarkt unerwünschten oder weniger erwünschten sozialen Merkmale zu erweitern. Vermieter:innen wählen häufig nach sozialer Ähnlichkeit. Dies zeigt, dass eine (Wieder-)Erschließung von bislang ungenutztem Wohnraum nicht nur räumliche Ressourcen nutzbar macht, sondern auch das Wagnis neuer Nachbarschaften zu moderieren vermag. Allerdings sind direkte Szenarien von Aufspüren der Angebote und Organisieren der Wohnraumvermittlung mit Kontextsensibilität und Lebensweltbezug umzusetzen

Clumped isotope record of salinity variations in the Subboreal Province at the Middle–Late Jurassic transition

Results of clumped isotope, oxygen isotope and elemental (Mg/Ca, Sr/Ca) analyses of exceptionally well-preserved belemnite rostra and ammonite shells from the uppermost Callovian–Upper Kimmeridgian (Lamberti–Mutabilis zones) of the Russian Platform are presented. Despite a significant decrease in belemnite δ18O values across the Upper Oxfordian–Lower Kimmeridgian, the clumped isotope data show a constant seawater temperature (ca. 16 °C) in the studied interval. The decrease in belemnite δ18O values and lower δ18O values measured from ammonite shells are interpreted as a result of the salinity decline of the Middle Russian Sea of ca. 12‰, and salinity stratification of the water column, respectively. The postulated secular palaeoenvironmental changes are linked to the inflow of subtropical, saline waters from the Tethys Ocean during a sea-level highstand at the Middle–Late Jurassic transition, and progressive isolation and freshening of the Middle Russian Sea during the Late Oxfordian–Kimmeridgian. The obtained clumped isotope data demonstrate relative stability of the Late Jurassic climate and a paramount effect of local palaeoceanographic conditions on carbonate δ18O record of shallow epeiric seas belonging to the Subboreal Province. Variations in Mg/Ca and Sr/Ca ratios of cylindroteuthid belemnite rostra, which are regarded by some authors as temperature proxies, are, in turn, interpreted to be primarily dependent on global changes in seawater chemistry. The paleoenvironmental variations deduced from clumped and oxygen isotope records of the Russian Platform correspond well with changes in local cephalopod and microfossil faunas, which show increasing provincialism during the Late Oxfordian and the Early Kimmeridgian. Based on the review of literature data it is suggested that the observed salinity decrease and restriction of Subboreal basins during the Late Jurassic played a major role in the formation of periodic bottom water anoxia and sedimentation of organic rich facies

Detailed stratified GWAS analysis for severe COVID-19 in four European populations

Given the highly variable clinical phenotype of Coronavirus disease 2019 (COVID-19), a deeper analysis of the host genetic contribution to severe COVID-19 is important to improve our understanding of underlying disease mechanisms. Here, we describe an extended genome-wide association meta-analysis of a well-characterized cohort of 3255 COVID-19 patients with respiratory failure and 12 488 population controls from Italy, Spain, Norway and Germany/Austria, including stratified analyses based on age, sex and disease severity, as well as targeted analyses of chromosome Y haplotypes, the human leukocyte antigen region and the SARS-CoV-2 peptidome. By inversion imputation, we traced a reported association at 17q21.31 to a ~0.9-Mb inversion polymorphism that creates two highly differentiated haplotypes and characterized the potential effects of the inversion in detail. Our data, together with the 5th release of summary statistics from the COVID-19 Host Genetics Initiative including non-Caucasian individuals, also identified a new locus at 19q13.33, including NAPSA, a gene which is expressed primarily in alveolar cells responsible for gas exchange in the lung.S.E.H. and C.A.S. partially supported genotyping through a philanthropic donation.
