Semiclassical limit for Schr\"odinger equations with magnetic field and Hartree-type nonlinearities

The semi-classical regime of standing wave solutions of a Schr\"odinger equation in presence of non-constant electric and magnetic potentials is studied in the case of non-local nonlinearities of Hartree type. It is show that there exists a family of solutions having multiple concentration regions which are located around the minimum points of the electric potential.Comment: 34 page

MANAGING EUROPEAN CORN BORER RESISTANCE TO BT CORN WITH DYNAMIC REFUGES

We develop a dynamic bioeconomic model of temporally optimal dynamic refuge recommendations for resistance management when a backstop technology arrives at a known date. The impact of the characteristics of the backstop on the use of the current technology, and the difference between static and dynamic refuges are examined.Crop Production/Industries,

MANAGING THE RISK OF EUROPEAN CORN BORER RESISTANCE TO TRANSGENIC CORN: AN ASSESSMENT OF CONTROVERSIAL REFUGE RECOMMENDATIONS

A bioeconomic model is developed to evaluate the tradeoff between the risk of resistance and increased productivity when refuge is planted in conjunction with transgenic pesticidal corn. The model is used to evaluate controversial refuge recommendations when producers are allowed to treat refuge in years of high pest pressure.Productivity Analysis, Research and Development/Tech Change/Emerging Technologies, Risk and Uncertainty,

Il territorio di Divjakë, paesaggi in competizione

La regione costiera di Divjakë, in Albania è da tempo soggetta ad una crescente domanda di sviluppo territoriale ed economico. Diverse immagini di trasformazione e altrettanti progetti di sfruttamento turistico di questa costa fragile e dinamica sono posti attualmente in competizione. Il programma di cooperazione URBAN LAB , intrapreso recentemente ha come obiettivo principale la costruzione di una alternativa realistica e innovativa ai modelli dominanti di turismo costiero, in gran parte dipendenti dagli investimenti esteri. Obiettivo generale di Urban Lab è favorire lo sviluppo territoriale, ambientale e turistico delle aree costiere lagunari. Nella regione di Divjakë, ciò si traduce in una serie di azioni volte a promuovere lo sviluppo socio-economico, attraverso un modello partecipato di gestione e promozione delle risorse locali: un laboratorio urbano, con la partecipazione attiva dei giovani, della società civile e delle istituzioni locali. L’approccio innovativo di questo programma di cooperazione consiste nella stretta associazione di un progetto di riscrittura del paesaggio, con un progetto di formazione rivolto alle popolazioni locali. Il programma di lavoro recentemente inaugurato, mentre costruisce una nuova immagine del territorio, propone al contempo strumenti di progetto in grado di porsi in una posizione intermedia tra l’ascolto dei bisogni e delle aspettative della società e la ricostruzione di una pratica di gestione territoriale legittima e condivisa.In recent decades, Divjake region, on Albania Mediterranean coast, has been subject to an increasing demand for local economic development. Different transformation perspectives and contrasting tourism development strategies are competing on this fragile but dynamic region. The cooperation program Urban Lab, recently undertaken, aims at the provision of a realistic and innovative strategy as an alternative to mainstream programs of mass-tourism seaside development, which are largely dependent on international investments. As a general objective, Urban Lab, promotes environment protection and tourism development on the coast and in the lagoon area. A range of actions trigger innovation in socioeconomic development through a participative planning process while reinforcing local resources. In this perspective, an urban laboratory with the active involvement of young people, civil society and institutions is foreseen. The innovative approach entails the association between a territorial project, reframing local landscape, and an educational program addressed to local residents. The research program, thus, positions itself at an intermediate level between the reception of society needs or expectations and the reconstruction of a legitimate and participated planning practice

Down-regulation of PIP1 aquaporin in poplar trees is detrimental to recovery from embolism

During their lifecycles, trees encounter multiple events of water stress that often result in embolism formation and temporal decreases in xylem transport capacity. The restoration of xylem transport capacity requires changes in cell metabolic activity and gene expression. Specifically, in poplar (Populus spp.), the formation of xylem embolisms leads to a clear up-regulation of plasma membrane protein1 (PIP1) aquaporin genes. To determine their role in poplar response to water stress, transgenic Populus tremula × Populus alba plants characterized by the strong down-regulation of multiple isoforms belonging to the PIP1 subfamily were used. Transgenic lines showed that they are more vulnerable to embolism, with 50% percent loss of conductance occurring 0.3 MPa earlier than in wild-type plants, and that they also have a reduced capacity to restore xylem conductance during recovery. Transgenic plants also show symptoms of a reduced capacity to control percent loss of conductance through stomatal conductance in response to drought, because they have a much narrower vulnerability safety margin. Finally, a delay in stomatal conductance recovery during the period of stress relief was observed. The presented results suggest that PIP1 genes are involved in the maintenance of xylem transport system capacity, in the promotion of recovery from stress, and in contribution to a plant’s control of stomatal conductance under water stress

Participatory design, beyond the local

This workshop aims at stimulating and opening a debate around the capacity of Participatory Design (PD) and other co-design approaches to deliver outcomes and methodologies that can have an impact and value for reuse well beyond the local context in which they were originally developed. This will be achieved by stimulating the submission of position papers by researchers from the PD community and beyond.These papers will be discussed during the workshop in order to identify challenges, obstacles but also potentials for scaling up PD processes and results from the local to the global.</p
