An Interactive Procedure for Multiobjective Analysis of Water Resources Allocation

This paper reports on part of IIASA's research concerning regional water management planning, focusing on the Western Skane region in Southern Sweden. The IIASA studies are concerned with four issues of particular importance to water resources management, namely, conflict resolution, criteria of choice, uncertainty, and institutional arrangements. This paper is related primarily to the first two of these issues. An interactive procedure seeking the satisfactory nondominated solution of the multiobjective water resources allocation problem is discussed. It is based on the Powell method with penalty function for the solution of scalar optimization problem and on a constraint and weighting method, or actually a reference objective method, for the solution of the multiobjective optimization problem. Application of the procedure is illustrated by an example referring to the situation in the Kavlinge River system in the Western Skane, Sweden

Water Resources Planning and Management in Advanced Economies: The Case Study of Western Skane, Sweden - A Background Report

This is a Working Paper intended to give background information on the Western Skane case study of water resource planning and management which is being pursued jointly by IIASA and Lund University. The paper is primarily intended to be read by a non-Swedish public. We have, however, also included some discussion of the most important analytical and policy-oriented problems of the Skane area, which means that some of the information is also of interest to a Swedish public. The presentation in this paper is based on currently available published information on the economic and administrative structure and environmental conditions related to water planning in the region. A preliminary version of the paper was distributed for review to planning agencies at the central and regional level of decision making. Our interpretation of their comments have been included in this final version. We have abstained from including discussions about modeling and other methodological issues at this stage. Such methodological issues will be presented in separate papers. It is also the intention to present a research plan based on this paper and other methodological research currently pursued at IIASA. The research plan is intended to cover a working period of approximately two years at IIASA and to be fitted into a four to five year research plan for the group working with these issues in Sweden

Multi-criteria Spatial Analysis for the Localization of Production Structures. Analytic Hierarchy Process and Geographical Information System in the Case of Expanding an Industrial Area

Among the numerous economic evaluation techniques currently available, multi-criteria spatial analysis lends itself to solving localization problems of property complexes and, in particular, production plants. The methodology involves the use of Geographical Information Systems (GIS) and the mapping overlay technique, which overlaps the different information layers of a territory in order to obtain an overview of the parameters that characterize it. This first phase is used to detect possible settlement surfaces of a new agglomeration, subsequently selected through Analytic Hierarchy Process (AHP), so as to choose the best alternative. The result ensures the synthesis of a multidimensional profile that expresses both the quantitative and qualitative effects. Each criterion can be given a different weight

Iron(III)-catalyzed chlorination of activated arenes

A general and regioselective method for the chlorination of activated arenes has been developed. The transformation uses iron(III) triflimide as a powerful Lewis acid for the activation of N-chlorosuccinimide and the subsequent chlorination of a wide range of anisole, aniline, acetanilide and phenol derivatives. The reaction was utilized for the late-stage mono- and di-chlorination of a range of target compounds such as the natural product nitrofungin, the antibacterial agent chloroxylenol and the herbicide chloroxynil. The facile nature of this transformation was demonstrated with the development of one-pot tandem iron-catalyzed dihalogenation processes allowing highly regioselective formation of different carbon-halogen bonds. The synthetic utility of the resulting dihalogenated aryl compounds as building blocks was established with the synthesis of natural products and pharmaceutically relevant targets

The impact of the Art Therapy Large Group, an educational tool in the training of art therapists, on post-qualification professional practice

This article reports the findings of a Likert scale survey that was sent to past graduates of the MA Art Psychotherapy, Goldsmiths, University of London asking them about the relevance of their experience in the Art Therapy Large Group (ATLG) to their subsequent employment as art therapists or work in another capacity. The ATLG comprises all the students and staff in a psychodynamically based experiential group that meets six times during the year. Survey questions were drawn from previously devised theory and related to learning relevant to the workplace and the development of professional identity. Though there was a low response rate (20%), there were some significant findings, namely that graduates found the ATLG to be helpful in their work, whether this was art therapy or non-art therapy work, and that those who had studied part-time were much more positive about the applicability of their learning in the group to their work than those who had studied full-time. The findings suggest that the ATLG has a particular role in meeting key performance indicators in professional regulation and teaching and in quality assurance and employability policies in higher education. Finally, the potential for the use of the ATLG beyond the university in the public, private and voluntary sectors is suggested

'They’ve Got Their Wine Bars, We’ve Got Our Pubs’: Housing, diversity and community in two south London neighbourhoods

This chapter explores how housing policies and the nature of housing stock have conditioned residential geographies and diversity patterns in two south London neighbourhoods, Bermondsey and Camberwell. The key drivers are policy changes to social housing allocation and the post-industrial reconfiguration of urban space expressed in processes of gentrification and the redevelopment of riverside docklands into expensive housing units. These developments have challenged existing narratives of community, but they have also shifted the focus of analytical enquiry towards emerging us-them divides based on class and generation. Within the context of diversity and social cohesion, both neighbourhoods are characterized by a comparatively unproblematic day-to-day muddling along with difference, but also a generally declining level of civic engagement and neighbourhood cohesion, expressed by a sense of ‘living together apart

The complete 1/N expansion of colored tensor models in arbitrary dimension

In this paper we generalize the results of [1,2] and derive the full 1/N expansion of colored tensor models in arbitrary dimensions. We detail the expansion for the independent identically distributed model and the topological Boulatov Ooguri model

Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}} = 2.76 TeV

Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross section. The measured charged particle spectra in $|\eta|<0.8$ and $0.3 < p_T < 20$ GeV/$c$ are compared to the expectation in pp collisions at the same $\sqrt{s_{\rm NN}}$, scaled by the number of underlying nucleon-nucleon collisions. The comparison is expressed in terms of the nuclear modification factor $R_{\rm AA}$. The result indicates only weak medium effects ($R_{\rm AA} \approx$ 0.7) in peripheral collisions. In central collisions, $R_{\rm AA}$ reaches a minimum of about 0.14 at $p_{\rm T}=6$-7GeV/$c$ and increases significantly at larger $p_{\rm T}$. The measured suppression of high-$p_{\rm T}$ particles is stronger than that observed at lower collision energies, indicating that a very dense medium is formed in central Pb-Pb collisions at the LHC.Comment: 15 pages, 5 captioned figures, 3 tables, authors from page 10, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/98

Two-pion Bose-Einstein correlations in central Pb-Pb collisions at sNN\sqrt{s_{\rm NN}} = 2.76 TeV

The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. The pion homogeneity volume and the decoupling time are significantly larger than those measured at RHIC.Comment: 17 pages, 5 captioned figures, 1 table, authors from page 12, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/388

Strange particle production in proton-proton collisions at s=0.9\sqrt{s}=0.9 TeV with ALICE at the LHC

The production of mesons containing strange quarks (K$^0_s$, $\phi$) and both singly and doubly strange baryons ($\Lambda$, Anti-$\Lambda$, and $\Xi$+Anti-$\Xi$) are measured at central rapidity in pp collisions at $\sqrt{s}$ = 0.9 TeV with the ALICE experiment at the LHC. The results are obtained from the analysis of about 250 k minimum bias events recorded in 2009. Measurements of yields (dN/dy) and transverse momentum spectra at central rapidities for inelastic pp collisions are presented. For mesons, we report yields () of 0.184 $\pm$ 0.002 stat. $\pm$ 0.006 syst. for K$^0_s$ and 0.021 $\pm$ 0.004 stat. $\pm$ 0.003 syst. for $\phi$. For baryons, we find = 0.048 $\pm$ 0.001 stat. $\pm$ 0.004 syst. for $\Lambda$, 0.047 $\pm$ 0.002 stat. $\pm$ 0.005 syst. for Anti-$\Lambda$ and 0.0101 $\pm$ 0.0020 stat. $\pm$ 0.0009 syst. for $\Xi$+Anti-$\Xi$. The results are also compared with predictions for identified particle spectra from QCD-inspired models and provide a baseline for comparisons with both future pp measurements at higher energies and heavy-ion collisions.Comment: 33 pages, 21 captioned figures, 10 tables, authors from page 28, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/387
