Memory performance of and-parallel prolog on shared-memory architectures

The goal of the RAP-WAM AND-parallel Prolog abstract architecture is to provide inference speeds significantly beyond those of sequential systems, while supporting Prolog semantics and preserving sequential performance and storage efficiency. This paper presents simulation results supporting these claims with special emphasis on memory performance on a two-level sharedmemory multiprocessor organization. Several solutions to the cache coherency problem are analyzed. It is shown that RAP-WAM offers good locality and storage efficiency and that it can effectively take advantage of broadcast caches. It is argued that speeds in excess of 2 ML IPS on real applications exhibiting medium parallelism can be attained with current technology

The StarLink Case: Issues for the Future

The disclosure in September 2000 that StarLink corn had been found in the human food supply putfood biotechnology in the public spotlight and caused concern among consumers and food systemstakeholders alike that a product approved only for animal use could find its way to grocery shelves. TheStarLink experience raises a number of issues that deserve study concerning the current regulatory systemand public policies affecting genetically modified foods. The issues include how to manage allergenicityissues posed by biotech foods at the approval stage. Most of the issues, however, involve post-approvalcontrol of staple food crops that have been genetically modified. It may be increasingly important in thefuture to maintain the identity of genetically modified crops and segregate them from conventional ones,yet neither the grain trading system nor the government regulatory system were designed to ensure this.This paper is the first step in a case study that Resources for the Future is conducting for the PewInitiative on Food and Biotechnology to identify and analyze the regulatory and public policy issuesraised by the StarLink episode. In this paper, we pose questions concerning the adequacy of curent legalauthority, regulatory procedures, and institutional arrangements for post-approval control of biotech foodsthat we intend to analyze in depth during the balance of the study based on interviews and other research.We welcome comment on this paper and the planned study.agricultural biotechnology, food allergens, food regulation, food safety, genetically modified food, grain trading system, StarLinkTM corn

Semiconductor cooling by thin-film thermocouples

Thin-film, metal alloy thermocouple junctions do not rectify, change circuit impedance only slightly, and require very little increase in space. Although they are less efficient cooling devices than semiconductor junctions, they may be applied to assist conventional cooling techniques for electronic devices

Technological Change and Gender Wage Differentials

This paper investigates the impact of non-neutral technological change on the recent narrowing of the gender wage differentials. The relation between technological change and relative wages of female and male workers is modeled through a constant elasticity of substitution production function that incorporates male and female labor inputs by occupation in each industry, a non-labor input and a productivity parameter function that captures non-neutral technological change. Data from 1979 to 2001 on employment and wages by industry and occupation come from the Current Population Survey. Using non-linear two stage least squares with cross-equation restrictions, the estimated results provide evidence that non-neutral technological change partially explains the documented narrowing of the gender wage gap during the 1980s and 1990s, even after controlling for unexplained differences in gender relative wages. Specifically, changes in non-neutral technological change explain between 5 % and 9 % of the overall increase of women’s wages relative to men’s in the sample. The strongest effect is found for the highest pay occupation level, while the smallest effect is found for the lower pay occupations. Finally, this paper brings evidence that ignoring the unexplained component of the gender wage differentials could result in a biased estimation of the effect on non-neutral technological change on the gender wage gap.

From the Northern Plains to the Carolina Coast: An Environmental Perspective on Nationwide Injunctions

This Note offers a perspective on nationwide injunctions informed by a selection of environmental cases from roughly the last two decades. In doing so, it attempts to draw broader conclusions about when, if ever, federal courts should prohibit the enforcement of environmental policies nationwide. This Note proceeds as follows: Part I defines “nationwide injunction,” discusses the recent history of nationwide injunctions against the federal executive branch, and describes the absence of a clear legal standard governing nationwide relief. Part II examines six environmental cases in which plaintiffs have sought, or federal courts have ordered, nationwide relief. Part III suggests that, in the context of environmental law, nationwide injunctions are justified when necessary to provide complete relief to plaintiffs and, as such, should remain an available remedy to the federal courts. However, Part III also argues that several of the rationales offered to support nationwide injunctions beyond providing complete relief should be retired. This abstract has been adapted from the author\u27s introduction

Beyond the Dalkon Shield: Proving Causation Against IUD Manufacturers for PID Related Injury

Intrauterine devices (IUDs)! have been linked to a wide variety of injuries to women, ranging from severe cramping, to spontaneous abortion, to sterility, to death. This Comment will focus on the problem of proving that scarring of the fallopian tubes, resulting in sterility or partial sterility, is causally linked to use of the IUD, and therefore, a provable element in a plaintiff\u27s cause of action against a manufacturer for such injuries
