MFD-2-TM-de: German Moral Foundation Dictionary 2 by Translation Matrix
<p>This dataset was created for the research paper: "Reiter-Haas, M., Kopeinik, S., & Lex, E. (2021, May). Studying moral-based differences in the framing of political tweets. In <em>Proceedings of the International AAAI Conference on Web and Social Media</em> (Vol. 15, pp. 1085-1089).". Available at <a href="https://ojs.aaai.org/index.php/ICWSM/article/view/18135/17938">https://ojs.aaai.org/index.php/ICWSM/article/view/18135/17938</a></p> <p>The translation were created using a translation matrix of positive and negative valence words. The dictionary was used to measure effects in the embedding space for which it is suitable. However, it is to note that the dictionary does not work in a classical sense, as it contains duplicates (e.g., words of the opposite poles). While this was also the case in the original dictionary (e.g., for "wound"), the effect has become much more pronounced in the translated version.</p> <p>Format:</p> <ul> <li>Lines starting with % denote a new section that the following words belong to (e.g., care.vice for harm).</li> <li>Otherwise, one word per line.</li> </ul> <p>For implementation details, refer to the <a href="https://github.com/socialcomplab/icwsm21-framing">GitHub Repo</a></p> <p> </p>

The Effect of Extracellular Matrix Stiffness on Inducing Adipogenic Differentiation of ADSCs
<p>Extracellular matrix (ECM) is a critical biophysical factor in adipose-derived stem cells differentiation. However, the specific regulatory mechanisms and signaling pathways of Yes-associated protein (YAP) are unknown, though it plays a critically important role in ECM-induced differentiation. Here, we embedded ADSCs in collagen hydrogels with varying stiffness, elastic moduli, to be exact, of 61Pa, 217Pa, and 321Pa. The expression of adipogenic-specific genes was highly correlated with stiffness of ECM<span>,</span> in addition, our study has found that the levels of YAP phosphorylation were significantly altered on the 9th day after stimulation with ECM stiffness. Staining of lipid droplets with BODIPY indicates that accumulation of lipid droplets depended on hydrogel stiffness; the most pronounced accumulation was registered in 321Pa hydrogels. By inhibiting the YAP signaling pathway, we found that lipid droplet accumulation increased; thus, inhibition of YAP signaling increased YAP phosphorylation in the cytoplasm, thereby promoting accumulation of lipid droplets. In conclusion, YAP played a crucial role in regulating ECM stiffness-induced adipogenic differentiation. Adipose stem cells are differentiated in a microenvironment that offers new insights into their differentiation process. </p>

HYDROUSA_ Evidence Matrix dataset
<p>The evidence matrix consists of cases demonstrating water reuse and recovery of other resources in cities, rural settlements, agriculture, coastal areas and industries, using technologies with Technology Readiness Level (TRL) 6 and above to recovery resources from wastewater, including NBS and any others. The aim was to identify cases demonstrated in Europe, and if the course of the search yielded cases demonstrated outside of Europe, but transferable to Europe, these were also taken up in the matrix (7 non-European cases, all located in the Southern Mediterranean). Demonstration cases include Horizon 2020 CIRC, WATER and WASTE and other EU-funded projects (total 96 cases), but also nationally funded projects (5 cases) and private sector projects (6 cases).<br>European and national-level policy and framework initiatives for circular water economy were collected, including signed Innovation Deals (1 Innovation Deal for water reuse identified), public strategies, action plans, laws, Directives, Regulations, financing programmes, platforms, tools and frameworks, all at EU level or national level in EU member states. The collection process involved screening of online databases and reports related to circular economy, with a focus on water and wastewater, as well as reports published by the European Commission, the European Environment Agency, EUROSTAT, Cradle to Cradle, the Ellen MacArthur Foundation and Circle Economy, among others.<br>The cases were categorized with key attributes to provide an overview and allow for filtering and targeted searching by users. Key information was retrieved from project websites, Cordis, reports and online articles.</p>
