Uncertainty in Widmark calculations:ABV variation in packaged versions of the most popular beers in the UK

Forensic practitioners regularly use the Widmark equation to determine theoretical blood alcohol concentrations for use in cases involving alcohol. It is important in these calculations to determine the uncertainty associated with any result. Previous work has investigated the uncertainty in %ABV from beers produced by small independent breweries in the UK but did not study the top selling beers. The top selling lagers and ales/bitters in the UK were identified by sales volume and the alcohol by volume determined. This data was then used to determine the percent coefficient of variation (%CV) that should be used by forensic practitioners when constructing alcohol technical defence reports for use in forensic cases. These samples, from what may be described as ‘big’ brewers, were determined to have a smaller root mean square error (RMSE) (±0.1%v/v, n = 35), and %CV than those previously reported for beers produced by small, independent breweries in the UK. The results from this study shows that different RMSE's should be used for %ABV when determining the uncertainty of results from Widmark calculations when drinks have been consumed from either ‘big’ brewers or small, independent breweries

Post-Employment, “Revolving Door,” Laws for Federal Personnel

[Excerpt] Conflict of interest regulations and restrictions on certain private employment opportunities for a federal officer or employee do not necessarily end with the termination of the officer’s or employee’s federal service. This report is intended to provide a brief history and description of the provisions of federal law restricting employment opportunities and activities of federal employees after they leave the service of the executive or legislative branches of the federal government. The conflict of interest provisions applicable after one leaves government service to enter private employment are often referred to as “revolving door” laws

Improving uncertainty in Widmark equation calculations:alcohol volume, strength and density

The Widmark equation is probably the most commonly used calculation for medicolegal purposes. Recently the National Research Council (USA) and the Forensic Science Regulator (UK) have called for the uncertainty of all results to be given with all forensic measurements and calculations. To improve the uncertainty of measurement of results from Widmark calculations we have concentrated on the uncertainties of measurement involved in the calculation of alcohol, that of the volume of alcohol, the concentration of alcohol and the density of alcohol as previous studies have investigated some of the other factors involved . Using experimental studies, the scientific literature and legal statutes, we have determined revised and improved uncertainties of the concentration of ethanol for Widmark calculations for both the USA and UK. Based on the calculations that we have performed we recommend the use of Monte Carlo Simulation for the determination of uncertainty of measurement for Widmark Calculations

Localised Low-tech Learning in the Furniture Industry

It is by now an established fact, that the so-called high technology industries have experienced growth rates way above average through most years. High technology industries share of the world manufacturers export has risen from 12 per cent in 1970 to 25 per cent in 1995. More than one-third of Japan's manufacturing export and more than 40 per cent of America's manufacturing export are products from high technology industries, and this development has increasingly led to an international obsession with high technology industries. In a number of countries R&D indicators have by now become the object of intense discussions. Great efforts are devoted to improve a bad relative standing. The aim of this paper is to questioned whether a national specialisation towards high technology industries is the only way by which the mature, developed countries can hope to sustain and augment their economic position. I claim that in contrast to much of the assumptions in contemporary politics and in the majority of the contemporary academic literature on the subject the countries without a specialisation in high technology industries are not left in the backwaters of economic development. Quite the contrary seems to be the case as many advanced, high-cost countries experience an above average economic performance even when specialising in the bottom end of the low-tech industries. The argument is illustrated with empirical material from the wooden furniture industry in general - and the rather successful Danish wooden furniture industry in particular. The possible reasons behind this apparent paradox are discussed.International competitiveness, industrial clusters, wooden furniture industry, level of technology

Learning in the Village Economy of Denmark. The role of Institutions and Policy in Sustaining Competitiveness.

The benefits of an international division of labour is never illustrated more clearly than in small developed nations like Denmark. Without many natural resources such countries can never be self sufficient and they need access to foreign markets in order for their firms to specialise and utilize economics of scale. The specialisation chosen is mainly in low-tech goods, where the risk of sudden domestically damaging changes in technology or demand are relatively small. Besides such general features of small developed nations, the Danish case has some special characteristics, which distinguishes it from many other nations and regions. One important feature is the century-old, deep-rooted egalitarian beliefs of the society which during the last century has intermixed with the growth of the public sector in shaping not only the welfare state, but also a strongly consensus-seeking political system - the negotiated economy - incorporating all major groups in the economy. Recently, the development towards a knowledge based world economy has increased the importance of another feature with an small egalitarian country: the kind of trust-relations, that come into existence, when everyone in an industry has known everybody else through many years. The international industrial competitiveness of the country's vast majority of small, export oriented firms are not only favoured by a reasonable adequate macro-economic policy but further enhanced by the ease in the exchange of information resulting from established trust-relations.International competitiveness, small nations, economic development, learning economy, informal institutions

Indicating Asynchronous Array Multipliers

Multiplication is an important arithmetic operation that is frequently encountered in microprocessing and digital signal processing applications, and multiplication is physically realized using a multiplier. This paper discusses the physical implementation of many indicating asynchronous array multipliers, which are inherently elastic and modular and are robust to timing, process and parametric variations. We consider the physical realization of many indicating asynchronous array multipliers using a 32/28nm CMOS technology. The weak-indication array multipliers comprise strong-indication or weak-indication full adders, and strong-indication 2-input AND functions to realize the partial products. The multipliers were synthesized in a semi-custom ASIC design style using standard library cells including a custom-designed 2-input C-element. 4x4 and 8x8 multiplication operations were considered for the physical implementations. The 4-phase return-to-zero (RTZ) and the 4-phase return-to-one (RTO) handshake protocols were utilized for data communication, and the delay-insensitive dual-rail code was used for data encoding. Among several weak-indication array multipliers, a weak-indication array multiplier utilizing a biased weak-indication full adder and the strong-indication 2-input AND function is found to have reduced cycle time and power-cycle time product with respect to RTZ and RTO handshaking for 4x4 and 8x8 multiplications. Further, the 4-phase RTO handshaking is found to be preferable to the 4-phase RTZ handshaking for achieving enhanced optimizations of the design metrics.Comment: arXiv admin note: text overlap with arXiv:1903.0943
