Quality here, there and everywhere: the application of a multi-dimensional learning tool to learning disability health services

The following paper examines the applicability of Maxwell’s (1984) Multi-dimensional Quality Evaluation model to community learning disability health services. The model defines seven dimensions against which the quality of any given service can be measured. Effectiveness, Efficiency, Economy, Equity, Access to Services, Appropriateness and Social Acceptability. A number of examples in relation to community learning disability services are given and discussed

Hydrologic simulation of storm water detention storage in an urbanizing flood-plan

Emerging concepts of urban flood control consider the use of storage detention, especially where channel capacities are being overtaxed by urban runoff. Particular problems exist where high rainfall intensities and low topographic relief combine with rapid urban development to produce potential flooding. Traditional approaches to flood control emphasize channelization of main streams and laterals to speed urban runoff out of developed areas. However, in low relief areas where the effect of urban drainage may be to greatly increase the peak flow rate and decrease the time to peak, flood control solutions of the 195's cannot handle the increasing development of the 197's. This has been experienced in rapidly growing coastal cities such as Houston, Texas. The purpose of the present study is to analyze the effect of detention storage placement and design on downstream flood flows in an urbanizing watershed. Effects of rainfall frequency, land use condition, and storage policy are directly considered in the methodology. The approach can be applied to any urban watershed in which historical rainfall data and streamflow data as well as land use information is available. The U.S. Army Corps of Engineers HEC-1 Model forms the basic tool for analysis of flood flows. A storage detention model is used in conjunction with empirical unit hydrographs which are derived as functions of land use. Storage detention is tested in both existing urban areas as well as projected future developments to discover effects on flood frequency flows. It is concluded that the ability to reduce the flooding potential of a rapidly urbanizing watershed with detention storage is limited by topography, remaining open space, and the presence of downstream development

IRRIGATION AND POTENTIAL DIVERSIFICATION BENEFITS IN HUMID CLIMATES

Income variability and means for managing risk continue to receive much attention in farm management research. In this paper, irrigation is presented as a risk-management strategy that offers potential diversification benefits. Potential diversification opportunities largely result from a wider range of enterprise production activities. A portfolio analysis of dryland and irrigated farm scenarios indicates that income stabilizing and diversification effects of irrigation substantially modify the risk-return position of a typical farm in northeast Louisiana. Safety-first considerations along with Target MOTAD programming procedures also are used to evaluate the impact of irrigation on the farm's financial performance.Farm Management,

The primordial and evolutionary abundance variations in globular-cluster stars: a problem with two unknowns

We demonstrate that among the potential sources of the primordial abundance variations of the proton-capture elements in globular-cluster stars proposed so far, such as the hot-bottom burning in massive AGB stars and H burning in the convective cores of supermassive and fast-rotating massive MS stars, only the supermassive MS stars with M > 10,000 Msun can explain all the observed abundance correlations without any fine-tuning of model parameters. We use our assumed chemical composition for the pristine gas in M13 (NGC6205) and its mixtures with 50% and 90% of the material partially processed in H burning in the 60,000 Msun MS model star as the initial compositions for the normal, intermediate and extreme populations of low-mass stars in this globular cluster, as suggested by its O-Na anti-correlation. We evolve these stars from the zero-age MS to the RGB tip with the thermohaline and parametric prescriptions for the RGB extra mixing. We find that the 3He-driven thermohaline convection cannot explain the evolutionary decline of [C/Fe] in M13 RGB stars, which, on the other hand, is well reproduced with the universal values for the mixing depth and rate calibrated using the observed decrease of [C/Fe] with MV in the globular cluster NGC5466 that does not have the primordial abundance variations.Comment: 11 pages, 1 table, 8 figures, accepted for publication in MNRA

Labor and Employment Law

It was a relatively quiet year in the Virginia labor and employment law arena, with no real groundbreaking cases or legislative enactments. There were developments in case law and legislative changes, but these were more subtle this year than in years past, and for the most part, the courts confirmed, affirmed, or clarified the existing state of the law. This article discusses cases and legislative activity of note in the Virginia labor and employment law arena during the past year. Part II addresses recent cases considering employment agreements under Virginia law. Part III considers cases in the continually evolving area of wrongful discharge claims. Part IV concerns employer liability for the wrongful acts of employees. Part V addresses defamation in the context of the employment relationship. Part VI discusses a recent case involving a misappropriation of trade secrets claim by an employer against its former employees. Part VII outlines recent developments in unemployment compensation law. Finally, Part VIII gives an overview of legislative developments during the 2005 Session of the Virginia General Assembl

Learning Hybrid Actor-Critic Maps for 6D Non-Prehensile Manipulation

Manipulating objects without grasping them is an essential component of human dexterity, referred to as non-prehensile manipulation. Non-prehensile manipulation may enable more complex interactions with the objects, but also presents challenges in reasoning about gripper-object interactions. In this work, we introduce Hybrid Actor-Critic Maps for Manipulation (HACMan), a reinforcement learning approach for 6D non-prehensile manipulation of objects using point cloud observations. HACMan proposes a temporally-abstracted and spatially-grounded object-centric action representation that consists of selecting a contact location from the object point cloud and a set of motion parameters describing how the robot will move after making contact. We modify an existing off-policy RL algorithm to learn in this hybrid discrete-continuous action representation. We evaluate HACMan on a 6D object pose alignment task in both simulation and in the real world. On the hardest version of our task, with randomized initial poses, randomized 6D goals, and diverse object categories, our policy demonstrates strong generalization to unseen object categories without a performance drop, achieving an 89% success rate on unseen objects in simulation and 50% success rate with zero-shot transfer in the real world. Compared to alternative action representations, HACMan achieves a success rate more than three times higher than the best baseline. With zero-shot sim2real transfer, our policy can successfully manipulate unseen objects in the real world for challenging non-planar goals, using dynamic and contact-rich non-prehensile skills.

Regionally acquired intestinal failure data suggest an underestimate in national service requirements

Objectives, setting and patients: With complete case referral for prolonged parenteral nutrition (PN) beyond term equivalent, serving a stable population of 1.25 million people, we describe the long-term outcome and survival of patients referred to an intestinal failure (IF) nutrition support team over the first 8 years of existence at a regional paediatric centre, and extrapolate to potential numbers of national home parenteral nutrition (HPN) cases and intestinal transplantation data. Design and outcome measures: Retrospective analysis detailing patient demographics, interventions, use of HPN, occurrence of intestinal failure-associated liver disease (IFALD), and outcomes of enteral adaptation, survival, and referral for and receipt of organ transplantation. Results: 23 patients were referred over 8 years, 20 being PN dependent within the neonatal period. Diagnoses included short bowel syndrome (SBS) (18), neuromuscular abnormalities (4) and congenital enterocyte disorder (1). 12 696 days of PN were delivered with 314 confirmed episodes of sepsis at a median of 12 episodes per patient. 144 central venous catheters (CVCs) were required at a median of four per patient. IFALD occurred in 17 (73%) patients, with 10 (44%) referred for transplant assessment. Thirteen (56%) children received HPN. Overall mortality was 44%. A significant predictor for survival in the SBS group was residual bowel >40 cm (82% vs 28%, p = 0.049). Conclusions: Survival for IF at 56% was lower than reported from non-UK supra-regional centres, and nationally collected data, possibly reflecting pre-selected referral populations. Data from regional centres with complete ascertainment may be important both when counselling parents and when planning regional and national HPN and IF specialist services
