Targeted precision biocontrol and pollination enhancement in organic cropping systems

Organic berry and fruit production suffers heavily from the lack of effective disease and pest management tools, and from inadequate insect pollination at times. As a consequence, the expanding demand on organic berries cannot be filled today. BICOPOLL expects to change this, and to significantly improve the yield and quality of organic fruit and berry production and thus, farm economics. We will use bees to (i) target deliver biological control agents to the flowers of the target crops to provide control of problem diseases (or pests), and to (ii) improve the pollination of organic horticultural crops. BICOPOLL will provide a pan-European case study on protecting organic strawberry from its most important disease, the grey mould. In addition we will improve the efficiency of the entomovector technology via innovative research on bee management, manipulation of bee behavior, components of the cropping system, and on the plant-pathogen-vector-antagonist –system, and will investigate possibilities of expanding the use of the concept into other organic berry and fruit growing systems. This is a highly innovative approach to solving some of the most difficult disease and pest problems in organic berry and fruit production, offering solutions in areas where no solutions as yet exist. The entomovector approach represents the only significant breakthrough in sight for improving plant protection in organic cropping systems, particularly in high-value crops. BICOPOLL brings together for the first time the fragmented research in the area, where small groups have worked on their own. We investigate, exploit, and support the natural ecological functions of biocontrol and pollination, and enhance these via innovative management. The entomovector technology contributes to improved resource use and efficiency in production, and enhances local biodiversity unlike most other plant protection systems. The main target groups of the BICOPOLL project are organic strawberry growers, other organic berry and fruit growers, as well as beekeepers and their organizations, to whom technology and knowledge transfer will be implemented during the project via direct contacts

Organization Development for Social Change

The field of organization development (OD) has emerged from efforts to improve the performance of organizations, largely in the for-profit sector but more recently in the public and not-for-profit sectors as well. This paper examines how OD concepts and tools can be used to solve problems and foster constructive change at the societal level as well. It examines four areas in which OD can make such contributions: (1) strengthening social change-focused organizations, (2) scaling up the impacts of such agencies, (3) creating new inter-organizational systems, and (4) changing contexts that shape the action of actors strategic to social change. It discusses examples and the kinds of change agent roles and interventions that are important for each. Finally, it discusses some implications for organization development intervention, practitioners, and the field at large.This publication is Hauser Center Working Paper No. 25.

Entanglement susceptibility: Area laws and beyond

Generic quantum states in the Hilbert space of a many body system are nearly maximally entangled whereas low energy physical states are not; the so-called area laws for quantum entanglement are widespread. In this paper we introduce the novel concept of entanglement susceptibility by expanding the 2-Renyi entropy in the boundary couplings. We show how this concept leads to the emergence of area laws for bi-partite quantum entanglement in systems ruled by local gapped Hamiltonians. Entanglement susceptibility also captures quantitatively which violations one should expect when the system becomes gapless. We also discuss an exact series expansion of the 2-Renyi entanglement entropy in terms of connected correlation functions of a boundary term. This is obtained by identifying Renyi entropy with ground state fidelity in a doubled and twisted theory.Comment: minor corrections, references adde

What Do Americans Think About Federal Transportation Tax Options? Results From Year 2 of a National Survey, Research Report 10-12

This report summarizes the results of a national random-digit-dial public opinion poll that asked 1,516 respondents if they would support various tax options for raising federal transportation revenues. The 11 specific tax options tested were variations on raising the federal gas tax rate, creating a new mileage tax, and creating a new federal sales tax. In addition, the survey collected standard socio-demographic data, some minimal travel behavior data, and attitudinal data about how respondents view the quality of their local transportation system and their priorities for government spending on transportation in their state. All of this information is used to assess support levels for the tax options among different population subgroups. The survey results show that a majority of Americans would support higher taxes for transportation—under certain conditions. For example, a gas tax increase of 10¢ per gallon to improve road maintenance was supported by 62% of respondents, whereas support levels dropped to just 24% if the revenues were to be used more generally to maintain and improve the transportation system. Other variants on a gas tax that received at least 50% support were increases of 10¢ per gallon with the revenues dedicated either to projects reducing accidents and improving safety or projects to “add more modern, technologically advanced systems.” For tax options where the revenues were to be spent for undefined transportation purposes, support levels varied considerably by what kind of tax would be imposed, with a sales tax much more popular than either a gas tax increase or a new mileage tax. A central goal of the survey was to compare public support for two alternative versions of a new mileage tax and eight versions of a gas tax increase. All variations on the two taxes increased support over that for the base case of each (a flat-rate mileage tax of 1¢ per mile and a 10¢ gas tax increase proposed without any additional detail). For example, varying the mileage tax by the vehicle’s pollution level increased support by 14 percentage points. For the gas tax, most notably, dedicating the tax proceeds to maintaining streets, roads, and highways increased support by 38 percentage points
