Applicability of a distributed watershed pollution model in a data-poor environment in Santa Catarina State, Brazil

Intensification of agricultural production without a sound management and regulations can lead to severe environmental problems, as in Western Santa Catarina State, Brazil, where intensive swine production has caused large accumulations of manure and consequently water pollution. Natural resource scientists are asked by decision-makers for advice on management and regulatory decisions. Distributed environmental models are useful tools, since they can be used to explore consequences of various management practices. However, in many areas of the world, quantitative data for model calibration and validation are lacking. The data-intensive distributed environmental model AgNPS was applied in a data-poor environment, the upper catchment (2,520 ha) of the Ariranhazinho River, near the city of Seara, in Santa Catarina State. Steps included data preparation, cell size selection, sensitivity analysis, model calibration and application to different management scenarios. The model was calibrated based on a best guess for model parameters and on a pragmatic sensitivity analysis. The parameters were adjusted to match model outputs (runoff volume, peak runoff rate and sediment concentration) closely with the sparse observed data. A modelling grid cell resolution of 150 m adduced appropriate and computer-fit results. The rainfall runoff response of the AgNPS model was calibrated using three separate rainfall ranges (< 25, 25-60, > 60 mm). Predicted sediment concentrations were consistently six to ten times higher than observed, probably due to sediment trapping along vegetated channel banks. Predicted N and P concentrations in stream water ranged from just below to well above regulatory norms. Expert knowledge of the area, in addition to experience reported in the literature, was able to compensate in part for limited calibration data. Several scenarios (actual, recommended and excessive manure applications, and point source pollution from swine operations) could be compared by the model, using a relative ranking rather than quantitative predictions.

Rahmenmodell vs. Geschäftsmodelle. Werkstattbericht zur Governance und zur Profilierung von aFuE an den schweizerischen Fachhochschulen

Die in den 1990er Jahren geschaffenen Fachhochschulen der Schweiz sind verpflichtet, in allen angebotenen Fachbereichen "anwendungsorientierte Forschung und Entwicklung" (aFuE) zu betreiben. Sowohl die Fachhochschulen wie auch die Fachbereiche sind allerdings sehr heterogen. Dieser Werkstattbericht zeigt auf, wie die Fachhochschulen das gesetzlich für alle gültige Rahmenmodell in zwei typologisch unterschiedlichen Geschäftsmodellen umsetzen: In einem am ökonomischen Markt ausgerichteten Modell A und in einem am Wissenschaftssystem und an ,,gesellschaftlichen Problemfeldern" ausgerichteten Modell B. Die beiden Typen stehen in einem Spannungsverhältnis zueinander, sind aber zugleich auch mit ähnlichen Problemen konfrontiert.

Recherche-action et gouvernance clinique: l'exemple du projet "psychiatrie et migrants" du CHUV [Action research and clinical governance: the example of the project "psychiatry and migrants" at the Centre hospitalier universitaire vaudois]

Action research is a useful instrument for the organization health care and the clinical governance of psychiatric institutions. What this type of research offers can be illustrated by the cohort study of migrant patients without health insurance who consulted the Department of Psychiatry of the Vaudois university medical center (CHUV) in 2008. While giving greater visibilty to the psychological suffering and social distress of these patients, the study also enabled the authors to determine which clinical procedures were actually offered to these patients and the amount these procedures cost the department. The small number of cases that were identified as well as their uneven distribution amongst the different services of the department suggest that considerable efforts must still be made to improve access for this population to public psychiatric services.

Transgenerational transmission of trauma in families of Holocaust survivors: The consequences of extreme family functioning on resilience, Sense of Coherence, anxiety and depression.

BACKGROUND: The psychological transmission of the noxious effects of a major trauma from one generation to the next remains unclear. The present study aims to identify possible mechanisms explaining this transmission among families of Holocaust Survivors (HS). We hypothesized that the high level of depressive and anxiety disorders (DAD) among HS impairs family systems, which results in damaging coping strategies of their children (CHS) yielding a higher level of DAD. METHODS: 49 CHS completed the Resilience Scale for Adults, the Hopkins Symptom Check List-25, the 13-Item Sense of Coherence (SOC) scale, and the Family Adaptability and Cohesion Scale. We test a mediation model with Family types as the predictor; coping strategies (i.e. Resilience or SOC) as the mediator; and DAD as the outcome variable. RESULTS: Results confirm that the CHS׳ family types are more often damaged than in general population. Moreover, growing in a damaged family seems to impede development of coping strategies and, therefore, enhances the occurrence of DAD. LIMITATIONS: The present investigation is correlational and should be confirmed by other prospective investigations. CONCLUSIONS: At a theoretical level we propose a mechanism of transmission of the noxious effects of a major trauma from one generation to the next through family structure and coping strategies. At a clinical level, our results suggest to investigate the occurrence of trauma among parents of patients consulting for DAD and to reinforce their coping strategies.

Rainfall erosivity and rainfall return period in the experimental watershed of Aracruz, in the coastal plain of Espirito Santo, Brazil

Knowledge on the factors influencing water erosion is fundamental for the choice of the best land use practices. Rainfall, expressed by rainfall erosivity, is one of the most important factors of water erosion. The objective of this study was to determine rainfall erosivity and the return period of rainfall in the Coastal Plains region, near Aracruz, a town in the state of Espírito Santo, Brazil, based on available data. Rainfall erosivity was calculated based on historic rainfall data, collected from January 1998 to July 2004 at 5 min intervals, by automatic weather stations of the Aracruz Cellulose S.A company. A linear regression with individual rainfall and erosivity data was fit to obtain an equation that allowed data extrapolation to calculate individual erosivity for a 30-year period. Based on this data the annual average rainfall erosivity in Aracruz was 8,536 MJ mm ha-1 h-1 yr-1. Of the total annual rainfall erosivity 85 % was observed in the most critical period October to March. Annual erosive rains accounted for 38 % of the events causing erosion, although the runoff volume represented 88 % of the total. The annual average rainfall erosivity return period was estimated to be 3.4 years.

Social Capital and Sport Governance in Europe

Although there is significant interest in the social role of sport in fostering civil society from both policymakers and academics, there is a lack of evidence of the specific role of sport federations in this system. This book critically presents the mechanisms and structures in a selection of sport federations within a variety of European countries that illuminate the varied relationships between not-for-profit sport federations, their members, governments and the citizens they represent. The contributors explore the contrasts and synergies between core social capital theoretical perspectives, and how these may be informed by and/or shape the realities of governance from different perspectives within the sport system.

Use of the swat model for hydro-sedimentologic simulation in a small rural watershed

Mathematical models have great potential to support land use planning, with the goal of improving water and land quality. Before using a model, however, the model must demonstrate that it can correctly simulate the hydrological and erosive processes of a given site. The SWAT model (Soil and Water Assessment Tool) was developed in the United States to evaluate the effects of conservation agriculture on hydrological processes and water quality at the watershed scale. This model was initially proposed for use without calibration, which would eliminate the need for measured hydro-sedimentologic data. In this study, the SWAT model was evaluated in a small rural watershed (1.19 km²) located on the basalt slopes of the state of Rio Grande do Sul in southern Brazil, where farmers have been using cover crops associated with minimum tillage to control soil erosion. Values simulated by the model were compared with measured hydro-sedimentological data. Results for surface and total runoff on a daily basis were considered unsatisfactory (Nash-Sutcliffe efficiency coefficient - NSE < 0.5). However simulation results on monthly and annual scales were significantly better. With regard to the erosion process, the simulated sediment yields for all years of the study were unsatisfactory in comparison with the observed values on a daily and monthly basis (NSE values < -6), and overestimated the annual sediment yield by more than 100 %.

Impacts of deforestation on water balance components of a watershed on the Brazilian East Coast

The Brazilian East coast was intensely affected by deforestation, which drastically cut back the original biome. The possible impacts of this process on water resources are still unknown. The purpose of this study was an evaluation of the impacts of deforestation on the main water balance components of the Galo creek watershed, in the State of Espírito Santo, on the East coast of Brazil. Considering the real conditions of the watershed, the SWAT model was calibrated with data from 1997 to 2000 and validated for the period between 2001 and 2003. The calibration and validation processes were evaluated by the Nash-Sutcliffe efficiency coefficient and by the statistical parameters (determination coefficient, slope coefficient and F test) of the regression model adjusted for estimated and measured flow data. After calibration and validation of the model, new simulations were carried out for three different land use scenarios: a scenario in compliance with the law (C1), assuming the preservation of PPAs (permanent preservation areas); an optimistic scenario (C2), which considers the watershed to be almost entirely covered by native vegetation; and a pessimistic scenario (C3), in which the watershed would be almost entirely covered by pasture. The scenarios C1, C2 and C3 represent a soil cover of native forest of 76, 97 and 0 %, respectively. The results were compared with the simulation, considering the real scenario (C0) with 54 % forest cover. The Nash-Sutcliffe coefficients were 0.65 and 0.70 for calibration and validation, respectively, indicating satisfactory results in the flow simulation. A mean reduction of 10 % of the native forest cover would cause a mean annual increase of approximately 11.5 mm in total runoff at the watershed outlet. Reforestation would ensure minimum flows in the dry period and regulate the maximum flow of the main watercourse of the watershed.

Payments for watershed services in Lombok, Indonesia : uncovering actors' strategies in a "success" story

This factsheet gives a short presentation of a case study conducted in Lombok Island (Indonesia). In 6 pages, it focuses on the complexity of PES scheme embedment in public policies. This factsheet describes and explicitly distinguishes three PES initiatives, and explain the reasons for such an evolution in the design of policy instruments aimed at protecting groundwater resources. The results presented have previously been published in an Working Paper: de Buren G., 2013.

Amélioration de l'hyperglycémie hospitalière: création d'un nouveau modèle de gouvernance [Improvement of hospital hyperglycemia: creation of a new governance model?].

The report of significant decrease of the inpatient hospital mortality and morbidity with an efficient insulin therapy has demonstrated the need of a good glycaemic control for patients hospitalised in acute care. However, one is faced with numerous difficulties in the hospital management of patients with hyperglycaemia, errors often occur when prescribing insulin, and the management skills are insufficient. Our goal is to change the medical and nursing practices to evolve towards an efficient and safe management of the hospitalised patient. The model we lay out in this article is based upon observation of the therapeutic support of patients with a chronic condition, whilst using a systemic management approach.

A Three-Dimensional Framework to Analyse the Governance of Population Registers

In June 2006, the Swiss Parliament made two important decisions with regards to public registers' governance and individuals' identification. It adopted a new law on the harmonisation of population registers in order to simplify statistical data collection and data exchange from around 4'000 decentralized registers, and it also approved the introduction of a Unique Person Identifier (UPI). The law is rather vague about the implementation of this harmonisation and even though many projects are currently being undertaken in this domain, most of them are quite technical. We believe there is a need for analysis tools and therefore we propose a conceptual framework based on three pillars (Privacy, Identity and Governance) to analyse the requirements in terms of data management for population registers.
