Mobility as a Service for the older population: a transport solution to land use changes in essential services?

Land use changes in relation to everyday services are resulting in centralisation of local services from mixed land use town centres to single land use destinations on the edge of cities. Technology advances are disrupting the provision of local community services such as local shops and local health care. Cost considerations and the benefits achieved by economies of scale are driving the land use changes which are changing the landscape of service provision. Whereas hospitals, for example, were typically located in city centres they are now more often in peripheral locations. For many sections of society, these changes have offered better convenience and higher quality of service. However, these changes have both spatial and horizontal equity impacts, particularly for older people and particularly for areas of lower density where accessibility will significantly decline. This paper explores the potential contribution of Mobility as a Service (MaaS) in promoting greater equity for older people using Community Transport (CT) as the service co-ordinator. The travel needs and behaviour of older people are reviewed as well as the contribution of flexible transport services towards meeting these needs. Drawing on discussions with a group of CT operators in Australia the key characteristics of the MaaS model are explored in the context of older people to ascertain whether CT acting as the service co-co-ordinator fits the MaaS model. A series of MaaS packages are proposed to show how the model could be delivered in practice. The paper concludes that as a business model, MaaS for CT could be one way of ameliorating the lack of equity for the old and frail age group brought about by land use changes in essential services

On the acceleration of wavefront applications using distributed many-core architectures

In this paper we investigate the use of distributed graphics processing unit (GPU)-based architectures to accelerate pipelined wavefront applications—a ubiquitous class of parallel algorithms used for the solution of a number of scientific and engineering applications. Specifically, we employ a recently developed port of the LU solver (from the NAS Parallel Benchmark suite) to investigate the performance of these algorithms on high-performance computing solutions from NVIDIA (Tesla C1060 and C2050) as well as on traditional clusters (AMD/InfiniBand and IBM BlueGene/P). Benchmark results are presented for problem classes A to C and a recently developed performance model is used to provide projections for problem classes D and E, the latter of which represents a billion-cell problem. Our results demonstrate that while the theoretical performance of GPU solutions will far exceed those of many traditional technologies, the sustained application performance is currently comparable for scientific wavefront applications. Finally, a breakdown of the GPU solution is conducted, exposing PCIe overheads and decomposition constraints. A new k-blocking strategy is proposed to improve the future performance of this class of algorithm on GPU-based architectures

An investigation of the performance portability of OpenCL

This paper reports on the development of an MPI/OpenCL implementation of LU, an application-level benchmark from the NAS Parallel Benchmark Suite. An account of the design decisions addressed during the development of this code is presented, demonstrating the importance of memory arrangement and work-item/work-group distribution strategies when applications are deployed on different device types. The resulting platform-agnostic, single source application is benchmarked on a number of different architectures, and is shown to be 1.3–1.5× slower than native FORTRAN 77 or CUDA implementations on a single node and 1.3–3.1× slower on multiple nodes. We also explore the potential performance gains of OpenCL’s device fissioning capability, demonstrating up to a 3× speed-up over our original OpenCL implementation

Srs2 promotes synthesis-dependent strand annealing by disrupting DNA polymerase δ-extending D-loops.

Synthesis-dependent strand annealing (SDSA) is the preferred mode of homologous recombination in somatic cells leading to an obligatory non-crossover outcome, thus avoiding the potential for chromosomal rearrangements and loss of heterozygosity. Genetic analysis identified the Srs2 helicase as a prime candidate to promote SDSA. Here, we demonstrate that Srs2 disrupts D-loops in an ATP-dependent fashion and with a distinct polarity. Specifically, we partly reconstitute the SDSA pathway using Rad51, Rad54, RPA, RFC, DNA Polymerase δ with different forms of PCNA. Consistent with genetic data showing the requirement for SUMO and PCNA binding for the SDSA role of Srs2, Srs2 displays a slight but significant preference to disrupt extending D-loops over unextended D-loops when SUMOylated PCNA is present, compared to unmodified PCNA or monoubiquitinated PCNA. Our data establish a biochemical mechanism for the role of Srs2 in crossover suppression by promoting SDSA through disruption of extended D-loops

Covenant Marriage Turns Five Years Old

Part I of this article discusses public policy rationales behind covenant marriage legislation, describes relevant aspects of Louisiana\u27s legislation, and summarizes the efforts of other states to enact covenant marriage legislation. Part II discusses methods of data collection and analysis and identifies the demographic characteristics of covenant married couples as opposed to standard married couples in Louisiana. Part III addresses the dynamics behind couples\u27 choice to have a covenant versus standard marriage. Part IV is an analysis of couples\u27 satisfaction with their marriage option and the gendered dynamics of different levels of satisfaction with the marital choice
