Risk and Uncertainty Analysis with Networks of Decisions

In this paper an applied approach for analysing economic problems under risk and uncertainty based on networks of decisions (NODs) will be discussed. It can be shown that network of decision analysis can help to understand complex decision problems under risk and uncertainty in single case situations. A variety of decision criteria like expectation values and a special ANOVA can be used to get better knowledge about prediction and controllability of the decision problems.networks of decisions, decision criteria, variance analysis, prediction, control, Risk and Uncertainty,

Stand und Entwicklungsperspektiven für ein europäisches Marktinformationssystem für Öko-Produkte

Für Produkte aus ökologischem Landbau liegen weder auf Länderebene noch auf EU-Ebene offizielle Statistiken über den Umfang von Produktion, Verbrauch und Außenhandel oder über Preise vor. Marktdaten oder –schätzungen von privaten Institutionen, so es sie überhaupt gibt, weichen in der Regel weit voneinander ab. Entscheidungen von Politikern und Marktakteuren, die diesen Markt betreffen, finden daher unter großer Unsicherheit statt. Im Rahmen eines europäischen Concerted Action Projektes wird daher versucht, ein europäisches Informationssystem für ökologische Märkte zu entwickeln. In diesem Beitrag werden die methodischen Probleme und erste Ergebnisse vorgestellt

Auf Herz und Niere : Etruskische Körperteilvotive der Gießener Antikensammlung

Die Klassische Archäologie an der Universität Gießen ist mit dem Deutschen Medizinhistorischen Museum Ingolstadt in einer äußerst fruchtbaren Kooperation verbunden. Vorläufiger Höhepunkt dieser Zusammenarbeit war die Ausstellung "Kultische Anatomie. Etruskische Körperteil-Votive aus der Antikensammlung der Justus-Liebig- Universität Gießen (Stiftung Ludwig Stieda)". Von Mitte März bis Mitte September 2008 waren rund 50 etruskische Votivterrakotten in Ingolstadt zu sehen, eingebettet in zahlreiche andere Kunstwerke der Gießener Antikensammlung, vor allem Vasen und Bronzeobjekte. Die Ausstellung fand nicht nur ein enormes öffentliches Interesse, sondern verdeutlichte auch das Potential, das in der wissenschaftlichen Auswertung dieses Komplexes noch steckt. Aus ihr ist ein internationales Forschungsprojekt erwachsen, an dem neben der Klassischen Archäologie in Gießen, dem Deutschen Medizinhistorischen Museum Ingolstadt, der Akademie der Bildenden Künste in Stuttgart und der AUDI-AG auch Forscher der Universitäten Nottingham und Philadelphia beteiligt sind

Report on proposals for the development, harmonisation and quality assurance of organic data collection and processing systems (DCPS)

This report represents the conclusion of the European seminar on development, harmonisation and quality assurance of organic data collection and processing systems (Berlin, April 2004) as well as of the first phase of the EISFOM-project. - In the first chapter the objectives and general approach of this workpackage are described. - Chapter 2 focuses on quality assurance, the main results of WP2 and WP3 and the European Seminar in Berlin (see Recke et al. 2004; https://orgprints.org/2935/. Furthermore, the strengths and weaknesses of organic DCPS (data collection and processing systems) are analysed and the chapter closes with proposals for the development of organic DCPSs. - Chapter 3 focuses on results of expert interviews on the main barriers for the implementation of improved organic statistical data collection and processing systems. - Chapter 4 gives a summary and some general conclusions are drawn. This report provides perspectives on how the above mentioned issues of the European Action Plan might be implemented

European Information System for Organic Markets (EISFOM QLK5-2002-02400): WP 2: “Data collection and processing systems (DCPS) for the conventional markets” and WP 3: “Data collection and processing systems for organic markets” = Deliverable D2

European markets for organic products are developing fast. In Europe, as other parts of the world, more and more farm land is being converted to organic production. In order to adjust production and consumption levels, detailed market information is needed, especially where decisions with a long-term impact need to be taken, for example on converting specific land or livestock enterprises requiring high levels of investment in glasshouses, housing, processing facilities etc. Since public subsidies (regional / national / European) are heavily involved in these investments, valid, accurate and up-to-date information is essential not only for farmers and growers, but also for policy-makers, consultants, processing industry etc. EU-research projects such as OFCAP (FAIR3-CT96-1794) and OMIaRD (QLK5-2000-01124) have shown that regional or national data gathering takes place in many countries, but often only very basic data are reported, such as certified organic holdings, land areas and livestock numbers. Important market data, e.g. the amount of production, consumption, international trade or producer and consumer prices, do not exist in most European countries. In some European countries there are only rough estimates of the levels of production and consumption. There is no standardization and data are seldom comparable. Furthermore, detailed information on specific commodities is missing. Hence, investment decisions are taken under conditions of great uncertainty. Likewise, if politicians want to support organic agriculture, they do not know whether it would be better to support production or consumption or to address problems in the marketing channel. The EU concerted action EISfOM (QLK5-2002-02400) (European Information System for Organic Markets) is attempting to take the first steps in solving these problems. The aim of this concerted action is to build up a framework for reporting valid and reliable data for relevant production and market sectors of the European organic sector in order to meet the needs of policy-makers, farmers, processors, wholesalers and other actors involved in organic markets. In order to reach this aim, this action was split into several workpackages. This report describes the approach and results of workpackages 2 and 3. In this first chapter the objective and general approach of these work packages are described. Chapters 2 and 3 provide an overview of international statistics and data collection systems within the food supply chain at the public and the private level. Chapter 4 describes national statistics and data collection systems within the food supply chain. In Chapter 5, an analysis and appraisal is made of the results with regard to organic data collection and processing systems (DCPSs) and their integration into existing common DCPSs. Chapter 6 draws several general conclusions. Two substantial annexes complete the report, one with the country reports on the situation of data collection and processing in all investigated countries and the other with the first and the second stage questionnaires covering the different data collection levels
