Bexley report: a report to MCCH on a suitable transport policy for its Bexley services

This report presents the findings of and recommendations from the study commissioned by MCCH to advise on a comprehensive transport policy for MCCH to use in providing services in both its residential homes and day-care centres in Bexley. It describes the current positions of transport supply for, and of transport demand by the community of people with learning difficulties in the London Borough of Bexley. It also considers the extent to which the transport supply is meeting or not meeting the transport demands and the expressed needs of the people and/or their representatives. The report considers the implications for improvement in transport provision of certain proposed actions by MCCH. Finally, the report presents some recommendations based on a user-centred strategy to help MCCH incorporate their concept of empowering their service users through suitable transport provision. This study has been conducted with the ethos and operational objectives of the MCCH group firmly in mind. MCCH has an objective to enhance quality of life for their service users and is very concerned with ensuring that its service users are enabled to exercise the rights and opportunities of citizenship with particular reference to freedom of choice in time and mode of travel. MCCH holds that real improvement in services to learning disability people must include increased range and choice of people-centred opportunities that address the total needs and aspirations of service users and their carers, underpinned by values and principles of good practice. Thus MCCH desires to put back in the control of users, the lever of decision making as regards services provided to 4 them and intends to do this by actively eliciting user/stakeholders involvement in decision-making. Contrary to the standard social service transport provision style, MCCH desires to create choice for service-users, feeling that people should be able to decide whether, e.g. to go by bus or train and be supported in their decision and not be constrained by the schedule of the provided transport. The specific terms of reference for this study are 1. To examine the current demand for, and provision of, transport within MCCH’s Bexley services. To assess how best these services might be reconfigured and managed, having regard to: · Desire to increase empowerment and choice for service users · Optimizing the integration of the transport management in Bexley within MCCH’s organization, in the light of most efficient use of resources and practice elsewhere in MCCH · Desire to better integrate residential services with day services in Bexley · MCCH’s intention to reconfigure Bexley day services · The move of service users towards ‘supported living’ as opposed to registered care · The objectives and concerns of all parties involved, including Bexley Social Services, Bexley Transport Services, the parents/relatives/carers of the service users and the service users themselves · The way vehicles are currently owned and funded · Efficiency and cost 2. To produce outline proposals, plans and specifications of how a reconfigured transport service would look and operate, including details of resource requirements in enough detail to allow reasonably accurate costing to be derived

Constraining anomalous Higgs interactions

The recently announced Higgs discovery marks the dawn of the direct probing of the electroweak symmetry breaking sector. Sorting out the dynamics responsible for electroweak symmetry breaking now requires probing the Higgs interactions and searching for additional states connected to this sector. In this work we analyze the constraints on Higgs couplings to the standard model gauge bosons using the available data from Tevatron and LHC. We work in a model--independent framework expressing the departure of the Higgs couplings to gauge bosons by dimension--six operators. This allows for independent modifications of its couplings to gluons, photons and weak gauge bosons while still preserving the Standard Model (SM) gauge invariance. Our results indicate that best overall agreement with data is obtained if the cross section of Higgs production via gluon fusion is suppressed with respect to its SM value and the Higgs branching ratio into two photons is enhanced, while keeping the production and decays associated to couplings to weak gauge bosons close to their SM prediction.Comment: v3: Added acknowledgment to FP7 ITN INVISIBLES (Marie Curie Actions PITN-GA-2011-289442).

Effects of electron transfer on the stability of hydrogen bonds.

The measurement of the dimerization constants of hydrogen-bonded ruthenium complexes (12, 22, 32) linked by a self-complementary pair of 4-pyridylcarboxylic acid ligands in different redox states is reported. Using a combination of FTIR and UV/vis/NIR spectroscopies, the dimerization constants (KD) of the isovalent, neutral states, 12, 22, 32, were found to range from 75 to 130 M-1 (ΔG0 = -2.56 to -2.88 kcal mol-1), while the dimerization constants (K2-) of the isovalent, doubly-reduced states, (12)2-, (22)2-, (32)2-, were found to range from 2000 to 2500 M-1 (ΔG0 = -4.5 to -4.63 kcal mol-1). From the aforementioned values and the comproportionation constant for the mixed-valent dimers, the dimerization constants (KMV) of the mixed-valent, hydrogen-bonded dimers, (12)-, (22)-, (32)-, were found to range from 0.5 × 106 to 1.2 × 106 M-1 (ΔG0 = -7.78 to -8.31 kcal mol-1). On average, the hydrogen-bonded, mixed-valent states are stabilized by -5.27 (0.04) kcal mol-1 relative to the isovalent, neutral, hydrogen-bonded dimers and -3.47 (0.06) kcal mol-1 relative to the isovalent, dianionic hydrogen bonded dimers. Electron exchange in the mixed valence states imparts significant stability to hydrogen bonding. This is the first quantitative measurement of the strength of hydrogen bonds in the presence and absence of electronic exchange

An Introduction to Community Detection in Multi-layered Social Network

Social communities extraction and their dynamics are one of the most important problems in today's social network analysis. During last few years, many researchers have proposed their own methods for group discovery in social networks. However, almost none of them have noticed that modern social networks are much more complex than few years ago. Due to vast amount of different data about various user activities available in IT systems, it is possible to distinguish the new class of social networks called multi-layered social network. For that reason, the new approach to community detection in the multi-layered social network, which utilizes multi-layered edge clustering coefficient is proposed in the paper.Comment: M.D. Lytras et al.

Inversion of spinning sound fields

A method is presented for the reconstruction of rotating monopole source distributions using acoustic pressures measured on a sideline parallel to the source axis. The method requires no \textit{a priori} assumptions about the source other than that its strength at the frequency of interest vary sinusoidally in azimuth on the source disc so that the radiated acoustic field is composed of a single circumferential mode. When multiple azimuthal modes are present, the acoustic field can be decomposed into azimuthal modes and the method applied to each mode in sequence. The method proceeds in two stages, first finding an intermediate line source derived from the source distribution and then inverting this line source to find the radial variation of source strength. A far-field form of the radiation integrals is derived, showing that the far field pressure is a band-limited Fourier transform of the line source, establishing a limit on the quality of source reconstruction which can be achieved using far-field measurements. The method is applied to simulated data representing wind-tunnel testing of a ducted rotor system (tip Mach number~0.74) and to control of noise from an automotive cooling fan (tip Mach number~0.14), studies which have appeared in the literature of source identification.Comment: Revised version of paper submitted to JASA; five more figures; expanded content with more discussion of error behaviour and relation to Nearfield Acoustical Holograph
