- This package contains data for the paper "Does (dis-)agreement reflect beliefs? An analysis of advocacy coalitions in Swiss pesticide policy". Paper abstract: Agricultural pesticide use is a wicked sustainability challenge: Trade-offs exist between health, environmental, agro-economic, and socio-political objectives. Various actors involved have diverse beliefs regarding these trade-offs and policies to address the challenge. But to what extent does the agreement or disagreement between actors reflect belief similarities or differences, and thus, the formation of advocacy coalitions? To answer this question, the study draws on the Advocacy Coalition Framework and investigates data from 54 key actors in the case of Swiss pesticide policy. The study explores the relationship between the actors’ (dis)agreement relations and their beliefs using Random Forests. Coalitions are identified through block modeling and beliefs based on Multi-Attribute Value Theory. The study shows that the two relations are a good proxy for identifying coalitions with conflict lines concerning beliefs and presents an approach to exploring ideological reasons behind (dis)agreement relations that supports identifying conflicting beliefs relevant to future policy solutions.1Licence not specified5 months ago
- In the framework of Ch2018, climate simulations were done in twenty-nine Swiss lakes, with three climate scenarios, and seventeen climate models from the start of 1981 to end of 2099. Lake variables in this dataset (temperature, stratification, ice cover) was obtain with the physical deterministic lake model Simstrat (v. 2.1.2).1Licence not specified5 months ago
- **There is [an older version](https://doi.org/10.25678/000044) of this dataset.** The dataset contains concentrations profiles of 213 agricultural pesticides in surface water samples. Half-day composite samples were taken from five small streams in Switzerland from the beginning of March to the end of August 2015. Half-day samples from discharge events were measured individually, whereas half-day samples taken during dry weather periods between discharge events were pooled to samples of variable lengths (five days on average) and then measured resulting in 34 to 60 measured samples per site.1Licence not specified5 months ago

- Ozone, electrolysis and granular activated carbon (GAC) were examined as potential post-treatments to follow a household-scale biologically activated membrane bioreactor (BAMBi), treating a wash water containing trace urine and feces contamination. Each post-treatment was evaluated for abilities and reaction preferences to remove or transform dissolved organic carbon (DOC), chemical structures that contribute color, and assimilable organic carbon (AOC), which can support bacterial regrowth. Batch treatment with each technology demonstrated an ability to remove ≥95% DOC. Ozone demonstrated a reaction selectivity through increased reaction rates with larger compounds and color-contributing compounds. Electrolysis and GAC demonstrated generally less-selective reactivity. Adding post-treatments to full-scale systems reduced DOC (55-91%), AOC (34-62%), and color (75-98%), without significant reaction selectivity. These reductions in DOC and AOC were not linked to reduction of bacterial concentrations in treated water. Reductions in bacterial concentrations were observed with ozone and electrolysis, but this is credited to oxidation chemicals produced in these systems and not the removal or transformations of organic materials.1Licence not specified5 months ago
- # Description Along river Glatt and river Chriesbach, spot samples were taken in an approximately weekly rhythm at five different stations from June 1972 to April 1977. In those samples physical, geochemical, anthropogenic parameters and heavy metals were measured. # Aim This project served as a pilot project for new extensive chemical examinations of flowing waters with regard to: - sample taking - sample preservation - chemical analysis - data preparation - data storage - data analysis - assessment of the water bodies Apart from this, strongly polluted water from river Glatt was analyzed. # Data Files - Glatt-Rheinsfelden - Glatt-Opfikon - Glatt-Niederglatt - Glatt-Glattfelden - Glatt-Faellanden - Glatt-Aubruecke_Hagenholz - Chriesbach-Duebendorf # Structure of the Data Files - measured data - loads - annual average of concentrations and loads - graphs of time series of concentrations and loads # Data source Chemical data are from Eawag and discharge data are from AWEL and FOEN # Publication List - Zobrist J. et al.

- # Description At the hydrological monitoring station Rhein - Schmitter aggregated samples were collected and analysed in an approximately weekly rhythm in 1972 and 1973. # Aim and Monitoring Program Based on the program of International Commission for the Protection of the Rhine (IKSR) to analyse the input of nutrients from tributary waters into lake Bodensee, the hydrological monitoring station Rhein - Schmitter was equipped for continious water sampling, measuring and data recording. The samples were taken in a weekly rhythm and analysed at EAWAG on components of nitrogen and phosphor proportional to the discharge. At high water discharge (Q > 330 m3/sec) samples were collected in a lower cadence into a separate collector (samples may therefore overlap in collection time). Averages of water temperature, pH or conductivity originate from the continuous recording. The data were published in the Hydrological Yearbook of Switzerland. # Origin of Data Data publication in the Hydrological Yearbook of Switzerland FOEN.1Licence not specifiedabout 1 year ago
- The files contain the data and the R scripts needed to replicate the analysis of three case study urban water systems as described in: Manny, L. (2022) Socio-technical challenges towards data-driven and integrated urban water management: a socio-technical network approach. https://doi.org/10.1016/j.scs.2022.104360 Data-driven and integrated urban water management have been proposed to reduce surface water pollution in light of climate change and urbanization impacts. Besides technological innovation, data-driven and integrated management require information exchange among many actors, e.g., operators, engineers, or authorities. With the aim of achieving a more profound understanding of socio-technical infrastructures, such as urban water systems, I draw on the approach of socio-technical networks to study actors and infrastructure elements as well as multiple relations in-between. In this article, I investigate whether underlying socio-technical dependencies influence social interactions such as information exchange. More specifically related to data-driven and integrated management, I analyze potential challenges, such as organizational fragmentation, data access, and diverging perceptions. Based on empirical data from three case studies in Switzerland, I provide inferential results obtained from fitting exponential random graph models. Findings showed that actors’ relatedness to infrastructure elements affects their information exchange. Among the cases, the presence of the three challenges varied and is potentially contingent upon system size, organizational form, or progress in terms of data-driven and integrated management. Thus, incorporating a socio-technical perspective on social actors and infrastructure elements could help to improve policy design and implementation aiming to achieve more sustainable cities.1Licence not specifiedover 1 year ago
