Common-property resources: privatization, centralization, and hybrid arrangements

This paper highlights Elinor Ostrom’s innovative and important work on common-property resources (CPRs), which helped earn her the Nobel Prize in Economics. In particular, she showed that neither privatization nor centralization necessarily would fix resource misallocation in CPRs. Ostrom recognized that common owners often developed effective governance that limited access to the CPR and promoted efficient transfers among generations. Through myriad approaches, she identified factors that foster efficient governance in hybrid institutions that are neither market nor state controlled. I use some simple games to illustrate her insights.     

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.     

Regime Types and Discrimination against Ethnoreligious Minorities: A Cross-Sectional Analysis of the Autocracy–Democracy Continuum

Although many assume that the relationship between the autocracy–democracy continuum and discrimination is linear, with autocracies discriminating the most and democracies discriminating the least, the assumption is not universal. This study uses the Minorities at Risk dataset to test this relationship with regard to government treatment of religiously differentiated ethnic minorities (ethnoreligious minorities) as well as ethnic minorities that are not religiously differentiated. The results show that the pattern of treatment of ethnoreligious minorities differs from that of other ethnic minorities. The extent to which a state is democratic has no clear influence on the level of discrimination against non-religiously differentiated ethnic minorities, but it has a clear influence on the level of discrimination against ethnoreligious minorities. Autocracies discriminate more than democracies against ethnoreligious minorities, but semi-democracies, those governments that are situated between democracies and autocracies, discriminate even less. This result is consistent on all 11 measures used here and is statistically significant for seven of them, and it remains strong when controlling for other factors, including separatism. This phenomenon increases in strength from the beginning to the end of the 1990s. Also, democracies discriminate against ethnoreligious minorities more than they do against other minorities. The nature of liberal democracy may provide an explanation for this phenomenon.     

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.     

The effect of jury nullification instruction on verdicts and jury functioning in criminal trials

Jury nullification is a mechanism, and a defense, which allows the jury, as representatives of the community, to disregard both the law and the evidence and acquit defendants who have violated the letter, but not the spirit of the law. Should juries simply follow the law as articulated by the trial judge, or should they act as “conscience of the community,” and neglect the strict requirements of the law when it would lead to unjust or inequitable verdicts? The present study was aimed at providing empirical data for the following question: will the jury operate in a manner which is different than its normal functioning if given explicit nullification instructions? Three nullification instructins varying in explicitness as to nullification were combined with three criminal cases to yield a 3×3 factorial design. Forty-five six-person juries (270 subjects), were randomly assigned to the nine experimental groups. The results showed that juries given explicit nullification instructtions were more likely to vote guilty in a drunk driving case, but less likely to do so in a euthanasia case. The third case, which dealt with murder, did not show any differences due to instructions. Juries in receipt of nullification instructions spent less deliberation time on the evidence and more on defendant characteristics, attributions, and personal experiences.     

A general theory of interpersonal exchange

A general theory of interpersonal exchange is developed from a public goods, public choice point of view and within an analytical context that assesses both the benefits and the costs of social interaction. Social transaction benefits and costs are specified as a composite function of interpersonal bindingness, which itself depends upon five parameters. The model provides for the determination of an optimal personal degree of bindingness in a two-person relationship. Extensions encompass the more interesting reaction case, where two individuals each select their own optimal personal bindingness levels. Applications and conclusions complete the paper. qu]When love beckons to you, follow him, Though his ways are hard and steep ... For even as love crowns you so shall he crucify you. Even as he is for your growth so is he for your pruning. Kahlil Gibran The Prophet     

Female and male sex offenders: a comparison of recidivism patterns and risk factors

Few studies have empirically validated the assertion that female and male sex offenders are vastly different. Therefore, utilizing a matched sample of 780 female and male sex offenders in New York State, the current study explored differences and similarities of recidivism patterns and risk factors for the two offender groups. Results suggested that male sex offenders were significantly more likely than female sex offenders to be rearrested for both sexual and nonsexual offenses. However, limited differences in terms of risk factors between female and male sex offenders were found.
