Beyond disability-adjusted life years (DALYs) : developing indicators to assess the impact of public health interventions on the lives of people with disabilities

This paper proposes two measures for assessing the impact of interventions on the lives of disabled people, the Activity Limitation Score (ALS) and the Participation restriction Score (PRS). These measures are closely linked to the World Health Organization's (WHO's) International Classification of Functioning, Disability and Health (ICF) and the social model of disability. The authors believe these measures can become important tools in monitoring the implementation of the recently ratified United Nations (UN) convention on the rights of persons with disabilities. The structure of this paper is as follows: after briefly describing the social model of disability and the ICF, the authors present a series of indicators for capturing the functional status of individuals. Then, using household survey data from Zambia, the authors explore the usefulness of this measure as it relates to economic development outcomes.Health Monitoring&Evaluation,Disease Control&Prevention,Population Policies,Disability,Housing&Human Habitats

Effective Inference for Generative Neural Parsing

Generative neural models have recently achieved state-of-the-art results for constituency parsing. However, without a feasible search procedure, their use has so far been limited to reranking the output of external parsers in which decoding is more tractable. We describe an alternative to the conventional action-level beam search used for discriminative neural models that enables us to decode directly in these generative models. We then show that by improving our basic candidate selection strategy and using a coarse pruning function, we can improve accuracy while exploring significantly less of the search space. Applied to the model of Choe and Charniak (2016), our inference procedure obtains 92.56 F1 on section 23 of the Penn Treebank, surpassing prior state-of-the-art results for single-model systems.Comment: EMNLP 201

Improving Neural Parsing by Disentangling Model Combination and Reranking Effects

Recent work has proposed several generative neural models for constituency parsing that achieve state-of-the-art results. Since direct search in these generative models is difficult, they have primarily been used to rescore candidate outputs from base parsers in which decoding is more straightforward. We first present an algorithm for direct search in these generative models. We then demonstrate that the rescoring results are at least partly due to implicit model combination rather than reranking effects. Finally, we show that explicit model combination can improve performance even further, resulting in new state-of-the-art numbers on the PTB of 94.25 F1 when training only on gold data and 94.66 F1 when using external data.Comment: ACL 2017.

Megahertz Schlieren Imaging of Shock Structure and Sound Waves in Under-Expanded, Impinging Jets

The accompanying fluid dynamics videos visualize the temporal evolution of shock structures and sound waves in and around an under-expanded jet that is impinging on a rigid surface at varying pressure ratios. The recordings were obtained at frame rates of 500 kHz to 1 Mhz using a novel pulsed illumination source based on a high power light emitting diode (LED) which is operated in pulsed current mode synchronized to the camera frame rate.Comment: Contribution to "Gallery of Fluid Motion", 63rd Annual APS-DFD Meeting, Long Beach (CA

What Can the United States Learn from the Nordic Model?

Some policymakers in the United States and Europe argue that it is possible to enjoy economic growth and also have a large welfare state. These advocates for bigger government claim that the socalled Nordic Model offers the best of both worlds. This claim does not withstand scrutiny. Economic performance in Nordic nations is lagging, and excessive government is the most likely explanation. The public sector in Sweden, Denmark, Norway, Finland, and Iceland consumes, on average, more than 48 percent of economic output. Total government outlays in the United States, by contrast, are less than 37 percent of gross domestic product. Revenue comparisons are even more striking. Tax receipts average more than 45 percent of GDP in Nordic nations, a full 20 percentage points higher than the aggregate tax burden in the United States. This bigger burden of government hurts Nordic competitiveness, both because government spending consumes resources that could be more efficiently allocated by market forces and because the accompanying high tax rates discourage productive behavior. A smaller state sector is one reason why the United States is more prosperous. Per capita GDP in the United States is more than 15 percent higher than it is in the Nordic nations. The gap is even larger when comparing disposable income, private consumption, and other measures that reflect living standards. Notwithstanding problems associated with a large welfare state, there is much to applaud in Nordic nations. They have open markets, low levels of regulation, strong property rights, stable currencies, and many other policies associated with growth and prosperity. Indeed, Nordic nations generally rank among the world's most market-oriented nations. Nordic nations also have implemented some pro-market reforms. Every Nordic nation has a lower corporate tax rate than the United States, for example, and most of them have low-rate flat tax systems for capital income. Iceland even has a flat tax for labor income. And both Iceland and Sweden have partially privatized their social security retirement systems. The Nordic nations offer valuable lessons for policymakers, but they do not fit the traditional stereotype. Conservative critics correctly condemn the large welfare states, but often overlook the positive results generated by laissez-faire policies in other areas. Liberals, meanwhile, exaggerate the economic performance of Nordic nations in an effort to justify welfare-state policies, while failing to acknowledge the role of freemarket policies in other areas

Remedies for Price Overcharges: The Deadweight Loss of Coupons and Discounts

This article evaluates two different remedies for consumers who have been injured by a price overcharge on the sale of a good. Under a coupon remedy, injured consumers are awarded coupons that can be used for a limited period of time to purchase the good at a price below that which prevails after the overcharge has been eliminated, that is, below the competitive price. Under a discount remedy, any consumer, without proof of injury, may purchase the good for a limited period of time at a price that is set below the competitive price. Both remedies generally cause consumers to buy an excessive amount of the good during the remedy period. Under the coupon remedy only a subset of consumers are affected in this way (those holding a relatively high number of coupons), while under the discount remedy all consumers are affected. We show nonetheless that the resulting deadweight loss could be lower under the discount remedy. We also consider how the deadweight loss changes when the length of the remedy period is increased by extending the expiration date for the use of coupons or by employing a lower discount for a longer period of time. The deadweight loss may or may not decline under the coupon remedy, though it does decline under the discount remedy. In neither case, however, does it go to zero in the limit.
