Business Planning for Climate Change: Identifying Vulnerabilities and Planning for Changes in Water,Temperature, Sea Level,Natural Resources,Health Effects,and Extreme Events

The ability to predict the timing and magnitude of future climate and temperature changes at a regional level has become increasingly important for corporate decision making and enterprise risk management. In the short term, companies could face decisions about acquisitions of water-dependent companies and natural resources or might be planning facilities or operations in communities vulnerable to erosion and flooding, changes in water supplies, and increasing health-care costs. In the intermediate term, companies need to assess these vulnerabilities to determine appropriate insurance coverage, plan for new infrastructure, implement preventative health-care programs, or protect natural resources. A technical approach needs to involve predictive tools that can provide bounding estimates at regional scales. The implications of those changes need to be translated to consequences that can affect specific businesses. Corporations must be cognizant of the uncertainties in this forecasting process and for that reason it is essential to link the likelihood of outcomes with the magnitudes of consequences. This article outlines an approach that is gaining traction as a way to address this complex matter.     

Analysis of artificially degraded DNA using STRs and SNPs--results of a collaborative European (EDNAP) exercise

Recently, there has been much debate about what kinds of genetic markers should be implemented as new core loci that constitute national DNA databases. The choices lie between conventional STRs, ranging in size from 100 to 450 bp; mini-STRs, with amplicon sizes less than 200 bp; and single nucleotide polymorphisms (SNPs). There is general agreement by the European DNA Profiling Group (EDNAP) and the European Network of Forensic Science Institutes (ENFSI) that the reason to implement new markers is to increase the chance of amplifying highly degraded DNA rather than to increase the discriminating power of the current techniques. A collaborative study between nine European and US laboratories was organised under the auspices of EDNAP. Each laboratory was supplied with a SNP multiplex kit (Foren-SNPs) provided by the Forensic Science Service, two mini-STR kits provided by the National Institute of Standards and Technology (NIST) and a set of degraded DNA stains (blood and saliva). Laboratories tested all three multiplex kits, along with their own existing DNA profiling technique, on the same sets of degraded samples. Results were collated and analysed and, in general, mini-STR systems were shown to be the most effective. Accordingly, the EDNAP and ENFSI working groups have recommended that existing STR loci are reengineered to provide smaller amplicons, and the adoption of three new European core loci has been agreed.     

Statistical analysis of barefoot impressions

Comparison of the shapes of barefoot impressions from an individual with footprints or shoes linked to a crime may be useful as a means of including or excluding that individual as possibly being at the scene of a crime. The question of the distinguishability of a person's barefoot print arises frequently. This study indicates that measurements taken from the outlines of inked footprint impressions show a great degree of variability between donors and a great degree of similarity for multiple impressions taken from the same donor. The normality of the set of measurements on footprint outlines that we have selected for this study is confirmed. A statistical justification for the use of the product rule on individual statistical precisions is developed.     

The effect of routine income withholding of child support collections

Recent federal legislation requires states to make substantial improvements in paternity establishment, enact numeric child support standards for determining child support awards, update those awards at least every three years, and adopt routine income withholding of all child support obligations. Data gathered for the purpose of evaluating the Wisconsin Child Support Assurance System make it possible to examine the effects of routine income withholding on the size and regularity of child support payments. The data consisted of court records of child support cases that entered the court system in 20 Wisconsin counties between 1980 and 1986. Our estimates suggest routine income withholding increases child support payments by between 11 and 30 percent.     

Joinder of criminal offenses: A review of the legal and psychological literature

Criminal courts routinely allow a defendant to be tried for multiple charges in a single trial. The practice is known as joinder of offenses. The issue of joinder of offenses is examined from a legal and psychological perspective. Relevant court decisions and their implications are discussed. In addition, the recent research conducted by social scientists concerning the possible reasons for the prejudicial effects of joinder of offenses is critically reviewed. Suggestions are offered, based upon previous joinder research, for the direction of future research into the loci of the effect and into potential remedies.This paper is an elaboration of one presented at the annual meeting of the Academy of Criminal Justice Sciences, Chicago, March 1984.
