Toward JUSTIS―A Research Program Aimed at Fostering Business Ethics by Empowering Stakeholders Through Information Systems

As incidents involving corporate social responsibility—or rather the lack thereof—hit headlines at regular intervals, stakeholders are becoming increasingly concerned about ethical issues, thus encouraging researchers to identify problematic business processes and pressing practitioners to start rectifying their questionable courses of action. In the meantime, information systems (IS) are becoming ever more pervasive and ubiquitous and are shaping and altering many of our everyday activities and behavior. We argue that when it comes to promoting ethical behaviors, IS can be used as powerful tools to empower stakeholders, and, thus, it is crucial to consider the role that IS can play in either advancing or deterring ethical—or conversely, unethical—behaviors. In this article, we present a research agenda for a new research program specifically concerned with the task of analyzing the social impact of existing IS and devising new ones that can be used to encourage ethical behavior. JustIS is the name of this program

Culture expansion of CAR T cells results in aberrant DNA methylation that is associated with adverse clinical outcome

Chimeric antigen receptor (CAR) T cells provide new perspectives for treatment of hematological malignancies. Manufacturing of these cellular products includes culture expansion procedures, which may affect cellular integrity and therapeutic outcome. In this study, we investigated culture-associated epigenetic changes in CAR T cells and found continuous gain of DNAm, particularly within genes that are relevant for T cell function. Hypermethylation in many genes, such as TCF7, RUNX1, and TOX, was reflected by transcriptional downregulation. 332 CG dinucleotides (CpGs) showed an almost linear gain in methylation with cell culture time, albeit neighboring CpGs were not coherently regulated on the same DNA strands. An epigenetic signature based on 14 of these culture-associated CpGs predicted cell culture time across various culture conditions. Notably, even in CAR T cell products of similar culture time higher DNAm levels at these CpGs were associated with significantly reduced long-term survival post transfusion. Our data demonstrate that cell culture expansion of CAR T cells evokes DNA hypermethylation at specific sites in the genome and the signature may also reflect loss of potential in CAR T cell products. Hence, reduced cultivation periods are beneficial to avoid dysfunctional methylation programs that seem to be associated with worse therapeutic outcome.This research was supported by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation − 363055819/GRK2415; WA1706/11–1; WA 1706/12–2 within CRU344/417911533; WA1706/14–1; and SFB 1506/1); and the ForTra gGmbH für Forschungstransfer der Else Kröner-Fresenius-Stiftung.

Methods for determining the CO2 removal capacity of enhanced weathering in agronomic settings

Recent analysis by the IPCC suggests that, across an array of scenarios, both GHG emissions reductions and various degrees of carbon removal will be required to achieve climate stabilization at a level that avoids the most dangerous climate changes in the future. Among a large number of options in the realm of natural climate solutions, atmospheric carbon dioxide removal (CDR) via enhanced silicate weathering (EW) in global working lands could, in theory, achieve billions of tons of CO2 removal each year. Despite such potential, however, scientific verification and field testing of this technology are still in need of significant advancement. Increasing the number of EW field trials can be aided by formal presentation of effective study designs and methodological approaches to quantifying CO2 removal. In particular, EW studies in working lands require interdisciplinary “convergence” research that links low temperature geochemistry and agronomy. Here, drawing on geologic and agronomic literature, as well as demonstration-scale research on quantifying EW, we provide an overview of (1) existing literature on EW experimentation as a CO2 removal technique, (2) agronomic and geologic approaches to studying EW in field settings, (3) the scientific bases and tradeoffs behind various techniques for quantifying CO2 removal and other relevant methodologies, and (4) the attributes of effective stakeholder engagement for translating scientific research in action. In doing so, we provide a guide for establishing interdisciplinary EW field trials, thereby advancing the verification of atmospheric CO2 in working lands through the convergence of geochemistry and agronomy

Iron status in women with infertility and controls: a case-control study

BackgroundIron deficiency is a common problem in subfertile women. The influence of iron status on unexplained infertility is unknown.MethodsIn a case-control study, 36 women with unexplained infertility and 36 healthy non-infertile controls were included. Parameters of iron status including serum ferritin and a serum ferritin <30 µg/dL served as main outcome parameters.ResultsWomen with unexplained infertility demonstrated a lower transferrin saturation (median 17.3%, IQR 12.7-25.2 versus 23.9%, IQR 15.4-31.6; p= 0.034) and a lower mean corpuscular hemoglobin concentration (median 33.6 g/dL, IQR 33.0-34.1 versus 34.1 g/dL, IQR 33.2-34.7; p= 0.012). Despite the fact that there was no statistically significant difference in median ferritin levels (p= 0.570), women with unexplained infertility had ferritin levels <30µg/L more often (33.3%) than controls (11.1%; p= 0.023). In a multivariate model, unexplained infertility and abnormal thyroid antibodies were associated with ferritin <30µg/L (OR 4.906, 95%CI: 1.181-20.388; p= 0.029 and OR 13.099; 2.382-72.044; p= 0.029, respectively).ConclusionFerritin levels <30µg/L were associated with unexplained infertility and might be screened in the future. Further studies with a focus on iron deficiency and iron treatment on women with unexplained infertility are warranted

Contested Heritage

In the wake of the Nazi regime’s policies, European Jewish cultural property was dispersed, dislocated, and destroyed. Books, manuscripts, and artworks were either taken by their fleeing owners and were transferred to different places worldwide, or they fell prey to systematic looting and destruction under German occupation. Until today, a significant amount of items can be found in private and public collections in Germany as well as abroad with an unclear or disputed provenance. Contested Heritage. Jewish Cultural Property after 1945 illuminates the political and cultural implications of Jewish cultural property looted and displaced during the Holocaust. The volume includes seventeen essays, accompanied by newly discovered archival material and illustrations, which address a wide range of topics: from the shifting meaning and character of the objects themselves, the so-called object biographies, their restitution processes after 1945, conflicting ideas about their appropriate location, political interests in their preservation, actors and networks involved in salvage operations, to questions of intellectual and cultural transfer processes revolving around the moving objects and their literary resonances. Thus, it offers a fascinating insight into lesser-known dimensions of the aftermath of the Holocaust and the history of Jews in postwar Europe

Model-based scenarios for achieving net negative emissions in the food system

Most climate mitigation scenarios point to a combination of GHG emission reductions and CO2 removal for avoiding the most dangerous climate change impacts this century. The global food system is responsible for ~1/3 of GHG emissions and thus plays an important role in reaching emission targets. Consumers, technology innovation, industry, and agricultural practices offer various degrees of opportunity to reduce emissions and remove CO2. However, a question remains as to whether food system transformation can achieve net negative emissions (i.e., where GHG sinks exceed sources sector wide) and what the capacity of the different levers may be. We use a global food system model to explore the influence of consumer choice, climate-smart agro-industrial technologies, and food waste reductions for achieving net negative emissions for the year 2050. We analyze an array of scenarios under the conditions of full yield gap closures and caloric demands in a world with 10 billion people. Our results reveal a high-end capacity of 33 gigatonnes of net negative emissions per annum via complete food system transformation, which assumes full global deployment of behavioral-, management- and technology-based interventions. The most promising technologies for achieving net negative emissions include hydrogen-powered fertilizer production, livestock feeds, organic and inorganic soil amendments, agroforestry, and sustainable seafood harvesting practices. On the consumer side, adopting flexitarian diets cannot achieve full decarbonization of the food system but has the potential to increase the magnitude of net negative emissions when combined with technology scale-up. GHG reductions ascribed to a mixture of technology deployment and dietary shifts emerge for many different countries, with areas of high ruminant production and non-intensive agricultural systems showing the greatest per capita benefits. This analysis highlights potential for future food systems to achieve net negative emissions using multifaceted “cradle-to-grave” and “land-to-sea” emission reduction strategies that embrace emerging climate-smart agro-industrial technologies
