Learning outcomes, learning support and cohort cohesion on a virtual field trip : an analysis of student and staff perceptions
Get PDFAcknowledgements We acknowledge the input of the students and staff who took part in the virtual field trip and contributed to the research by completing the surveys. The virtual field trip academic staff were Clare Bond, Rob Butler, Malcolm Hole, Colin North, Adrian Hartley, and Ian Alsop, who were involved in discussions on learning outcomes, course design, and delivery modes. The non-author PhD student demonstrators were Tom Theurer, Bartosz Kurjanski, and Sophie Berhendsen, who provided feedback on small group sessions.Peer reviewe
New risk indicator approach for Operators, Workers, Bystanders and Residents for a sustainable use of plant protection products
No full textIn 2009, the European Union adopted the Directive on Sustainable Use of pesticides (SUD, Directive 2009/128/EC) establishing a framework for achieving a sustainable use of Plant Protection Products (PPPs) through reducing the risks and impacts of PPP use on human health and the environment, promoting integrated pest management and stimulating effective non-chemical alternatives. The core idea of the SUD is that it is necessary to monitor the use of PPPs through the implementation of an appropriate set of risk indicators to monitor progress and trends in risk reduction within the Member States. To contribute to this direction, following a comprehensive analysis of the risk (including procedures of risk assessment and risk management) and involving stakeholders in the decision process, specific toolboxes of practical indirect risk indicators of exposure of Operators, Workers, Bystanders and Residents were developed and are now available to be used by Member States (MSs) based on their specific context

Effect of differences in international reference technique and evaluation zone on the classification of spray drift reducing techniques
No full textA series of spray drift experiments were conducted to classify a specific spray technique for the Netherlands, the United Kingdom and France. The candidate spray technique was equipped with three different nozzle types; a standard flat fan, a 50% and a 90% drift reducing nozzle type. In order to classify the sprayer for the spray drift reduction classification system in the Netherlands and the UK the reference spray technique used was a boom sprayer operating at 50 cm boom height, 50 cm nozzle spacing at 6.5 km h-1 forward speed and equipped with Tee Jet XR11004 flat fan nozzles operated at 3 bar spray pressure. For the French system, the reference spray technique was a boom sprayer operating at 70 cm boom height, at 8 km h1 forward speed and equipped with TeeJet XR11002 flat fan nozzles operated at 2.5 bar spray pressure. The classification against different reference spray techniques and evaluation zones (2-3 m; 2-6 m; 5 m) is presented for three candidate spray techniques based on comparative spray drift experiments under similar crop and weather conditions. Similarities and differences between the classifications following the different systems are highlighted. Results show a basis for the exchangeability of the classification of spray drift reducing techniques between the different classification systems based on field data and the potential for further harmonisation of certification procedures between countries
Volatilisation of pesticides under field conditions : inverse modelling and pesticide fate models
No full textBACKGROUND: A substantial fraction of the applied crop protection products on crops is lost to the atmosphere. Models describing the prediction of volatility and potential fate of these substances in the environment have become an important tool in the pesticide authorisation procedure at the EU level. The main topic of this research is to assess the rate and extent of volatilisation of ten pesticides after application on field crops. RESULTS: For eight of the ten pesticides, the volatilisation rates modelled with PEARL (Pesticide Emission Assessment at Regional and Local scales) corresponded well to the calculated rates modelled with ADMS (Atmospheric Dispersion Modelling System). For the other pesticides, large differences were found between the models. Formulation might affect the volatilisation potential of pesticides. Increased leaf wetness increased the volatilisation of propyzamide and trifloxystrobin at the end of the field trial. The reliability of pesticide input parameters, in particular the vapour pressure, is discussed. CONCLUSION: Volatilisation of propyzamide, pyrimethanil, chlorothalonil, diflufenican, tolylfluanid, cyprodinil and E- and Z-dimethomorph from crops under realistic environmental conditions can be modelled with the PEARL model, as corroborated against field observations. Suggested improvements to the volatilisation component in PEARL should include formulation attributes and leaf wetness at the time of pesticide application

'The Cloud of Unknowing': its inheritance and its inheritors
No full textThe thesis attempts a portrait of The Cloud in the context of its
position in the history of Christian mysticism. That the
anonymous work owed much to spiritual writers of the preceding
twelve hundred years is not debatable; what it owed maybe
slightly less obvious. The Cloud is essentially a work of
Dionysian mysticism, and various writers within that tradition
who may have influenced or affected the teaching of The Cloud are
examined. At the same time, however, the anonymous writer owes
much to the western tradition of Augustinian theology, and the
role of this, complementary to the Dionysian mysticism, is also
considered. In Chapter II we look at the theological doctrine
underlying the mystical doctrine of the Cloud corpus. Chapter
III has two major parts, both concerned with the influence of
The Cloud on the subsequent development of spiritual writing in
England. The first considers the relationship with Walter
Hilton. The second examines aspects of Puritan thought which may
indicate that the influence of The Cloud, after the Reformation,
was not restricted to Catholic thought
