Farm management issues in organic agriculture

Various aspects of farm management are analysed, which can be of interest for farmers, advisors and policy makers. The basic tools of management are recalled, as well as yields and labour demand

Organic olive oil and rural development: which services are required and who can supply them?

The paper deals with the different types of services which are required by organic producers of olive oil (training, advice, information, support for credit application, certification, marketing, etc., in the broader context of diversification of rural economies

Marketing issues in organic agriculture

The presentation deals with marketing channels and points of consumption, with data about Italy and Europe, to stimulate the debate about which marketing strategies could be more appropriate in a given environment

Organic agriculture and olive oil production in the Southern Mediterranean Countries

This presentation illustrates data from several researches, about present situation and prospects for OA in the south of the Med, and then focuses on organic olive management, production and trends

Future prospects in OA in Europe and the world, with respect to product diversification and markets

The presentation illustrates the status of organic agriculture and markets in Europe, indicating the growing role of supermarket chains, the motivations of consumers, the prospects for small and large producers, also within the framework of rural development (employement and added value

Organic olive oil from Italy

This presentation covers the production of conventional and organic olive oil and its trade from Italy to USA; it explains which type of controls are applied to conventional oils, as well as to GI oils and to organic ones

Collaborative research and sharing data ahead of paper publication: A case study of De Montfort University’s Dr. Fabio Caraffini

Figshare data• By sharing his high-resolution, multispectral images prior to a paper publication on DMU Figshare, Fabio and his colleagues are building public engagement with their research. • Storing large amounts of data in DMU Figshare allows Fabio and his colleagues to link to that data in a paper, which they would have otherwise just had to describe in the body of the paper

Scalable partitioning for parallel position based dynamics

We introduce a practical partitioning technique designed for parallelizing Position Based Dynamics, and exploiting the ubiquitous multi-core processors present in current commodity GPUs. The input is a set of particles whose dynamics is influenced by spatial constraints. In the initialization phase, we build a graph in which each node corresponds to a constraint and two constraints are connected by an edge if they influence at least one common particle. We introduce a novel greedy algorithm for inserting additional constraints (phantoms) in the graph such that the resulting topology is q-colourable, where ˆ qˆ ≥ 2 is an arbitrary number. We color the graph, and the constraints with the same color are assigned to the same partition. Then, the set of constraints belonging to each partition is solved in parallel during the animation phase. We demonstrate this by using our partitioning technique; the performance hit caused by the GPU kernel calls is significantly decreased, leaving unaffected the visual quality, robustness and speed of serial position based dynamics

Congestion, Private Peering and Capacity Investment on the Internet.

This paper presents a model of private bilateral and multilateral peering arrangements between Internet backbone providers when the network is congested. We study how different forms of interconnection and the competitive conditions of the market affect backbones' investments in network and peering point capacities. We show that network and peering point capacities are equilibrium complements; increasing competition reduces capacity investments (under-investment), thus worsening the quality of service both with multilateral and bilateral peering; under bilateral peering the inefficiency is less severe. Because of under-investment, welfare may be lower when the market is more competitive. We also show that asymmetries between backbones, which can take the form of uneven content distribution or product differentiation, may reduce under-investment and improve the quality of service. The introduction of an "inverse capacity interconnection fee" where providers pay each other a fee which is negatively correlated with their installed capacity may play the role of a coordinating mechanism towards a Pareto superior outcome.Internet, peering, congestion, QoS, capacity investment, interconnection

Dual licensing in open source software markets

Dual licensing has proved to be a sustainable business model for various commercial software vendors employing open source strategies. In this paper we study the main characteristics of dual licensing and under which conditions it represents a profitable commercial strategy. We show that dual licensing is a form of versioning, whereby the software vendor uses the open source licensing terms in order to induce commercial customers to select the proprietary version of the software. Furthermore, we show that the software vendor prefers dual licensing to a fully proprietary strategy when the customers are very sensitive to the reciprocal terms of the open source license
