Towards water literacy: an interdisciplinary analysis of standards for teaching and learning about humans and Water

Water is critical to sustain human existence. Water literacy involves understanding the interactions within and between natural and human dimensions of water systems to support informed decision-making, an important outcome for learners of all ages. It is therefore critical to foster water literacy in today’s global citizens, particularly through formal education. The purpose of this study, in tandem with a parallel study focusing on natural dimensions of water systems (Mostacedo-Marasovic et al., in press), is to examine water-related K-12 standards for teaching and learning about human dimensions of water systems to develop a comprehensive and transdisciplinary perspective on water education. Our overarching question is, “What do disciplinary standards specify as outcomes for students’ learning about water and humans?”. Our research questions are: i) “To what extent do these water-related standards address recognized domains of learning?” and ii) “What thematic outcomes for students’ learning are apparent across grades in these water-related standards?”. We use chi-square statistics and a conventional qualitative content analysis method complemented by processes from grounded theory to analyze water-related education standards (N = 341) from 12 education-oriented, governmental and non-governmental organizations based in the United States. Our results indicate that first, water-related standards emphasize the cognitive domain, including declarative and procedural knowledge. The affective domain and its social and emotional components are much less prevalent. Second, the water-related standards illustrate five categories which encompass human dimensions of water spanning K-12 grade bands, including human settlements; the nexus between water, food, and energy; public health; impacts of human activities on water quality and quantity; and water resources management. Overall, the study contributes to a more holistic and comprehensive perspective of water and human systems that can help inform teaching and learning to cultivate water literacy, including curriculum development and classroom pedagogy

Update of EULAR recommendations for the treatment of systemic sclerosis

The aim was to update the 2009 European League against Rheumatism (EULAR) recommendations for the treatment of systemic sclerosis (SSc), with attention to new therapeutic questions. Update of the previous treatment recommendations was performed according to EULAR standard operating procedures. The task force consisted of 32 SSc clinical experts from Europe and the USA, 2 patients nominated by the pan-European patient association for SSc (Federation of European Scleroderma Associations (FESCA)), a clinical epidemiologist and 2 research fellows. All centres from the EULAR Scleroderma Trials and Research group were invited to submit and select clinical questions concerning SSc treatment using a Delphi approach. Accordingly, 46 clinical questions addressing 26 different interventions were selected for systematic literature review. The new recommendations were based on the available evidence and developed in a consensus meeting with clinical experts and patients. The procedure resulted in 16 recommendations being developed (instead of 14 in 2009) that address treatment of several SSc-related organ complications: Raynaud's phenomenon (RP), digital ulcers (DUs), pulmonary arterial hypertension (PAH), skin and lung disease, scleroderma renal crisis and gastrointestinal involvement. Compared with the 2009 recommendations, the 2016 recommendations include phosphodiesterase type 5 (PDE-5) inhibitors for the treatment of SSc-related RP and DUs, riociguat, new aspects for endothelin receptor antagonists, prostacyclin analogues and PDE-5 inhibitors for SSc-related PAH. New recommendations regarding the use of fluoxetine for SSc-related RP and haematopoietic stem cell transplantation for selected patients with rapidly progressive SSc were also added. In addition, several comments regarding other treatments addressed in clinical questions and suggestions for the SSc research agenda were formulated. These updated data-derived and consensus-derived recommendations will help rheumatologists to manage patients with SSc in an evidence-based way. These recommendations also give directions for future clinical research in SSc
