SEX‐BASED DISPARITIES IN FELONY DISPOSITIONS BEFORE VERSUS AFTER SENTENCING REFORM IN OHIO*

Extending Koons‐Witt's (2002) study of whether sex‐based disparities in imprisonment likelihoods changed under sentencing guidelines in Minnesota, we examined similar models for Ohio with additional analyses of felony conviction likelihoods and sentence length for 5,472 felony defendants from twenty‐four trial courts. The main effects of a defendant's sex on imprisonment were significant during both periods (unlike the Minnesota findings), consistent with a chivalry perspective. Random coefficient models revealed that these effects were similar across the twenty‐four jurisdictions. Analyses also revealed significant postguideline reductions in sentence length disparities based on a woman's race and number of dependent children, yet increased disparities in imprisonment likelihoods postguidelines based on a woman's race and whether she was convicted on drug charges. These and other findings are discussed in the context of the Ohio legislature's implementation of a sentencing scheme that retains considerably more judicial discretion relative to Minnesota's template.     

Unemployment and the dynamics of offender populations

This paper models the increase in the participation rate of criminal behavior as either the initiation rate or the career length of criminals changes in response to increases in unemployment. Even with large instantaneous increases in unemployment, the models show a very slow increase in the criminal participation rate, giving a possible explanation of the failure of many studies to demonstrate a link between unemployment and crime levels.     

Microbial metagenome profiling using amplicon length heterogeneity-polymerase chain reaction proves more effective than elemental analysis in discriminating soil specimens

The combination of soil's ubiquity and its intrinsic abiotic and biotic information can contribute greatly to the forensic field. Although there are physical and chemical characterization methods of soil comparison for forensic purposes, these require a level of expertise not always encountered in crime laboratories. We hypothesized that soil microbial community profiling could be used to discriminate between soil types by providing biological fingerprints that confer uniqueness. Three of the six Miami-Dade soil types were randomly selected and sampled. We compared the microbial metagenome profiles generated using amplicon length heterogeneity-polymerase chain reaction analysis of the 16S rRNA genes with inductively coupled plasma optical emission spectroscopy analysis of 13 elements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, P, S, Si, and Zn) that are commonly encountered in soils. Bray-Curtis similarity index and analysis of similarity were performed on all data to establish differences within sites, among sites, and across two seasons. These data matrices were used to group samples that shared similar community patterns using nonmetric multidimensional scaling analysis. We concluded that while chemical characterization could provide some differentiation between soils, microbial metagenome profiling was better able to discriminate between the soil types and had a high degree of reproducibility, therefore proving to be a potential tool for forensic soil comparisons.     

The judicial response to crime and the criminal: A utilitarian perspective

This paper examines the hypothesis that the sentencing decision of the criminal court is consistent with utilitarian principles and that the judiciary uses the length of incarceration as an instrument for the maximization of societal well-being. A theoretical model is developed, whose principal arguments are offender and offense attributes, resource costs, the availability of alternative sanctions, and the general crime rate. Four questions are considered: (i) How does a utilitarian court respond to a general increase in crime? (ii) How does the availability of alternative sanctions affect the length of incarceration ? (iii) How does a utilitarian court respond to offenders who are more likely to recidivate? (iv) How does the court respond to offenders who commit more serious offenses? The model is empirically evaluated, using cross-sectional data for the state of Georgia for individuals sentenced to prison in 1978 for a UCR index offense. The theoretical model provides few specific behavioral rules for the court to follow. Answers to the foregoing four questions are shown to depend upon both the efficacy of sanctions and the cost of the administration of those sanctions. It is not possible to predict, for example, how a utilitarian court should respond to a rise in crime or how it should respond to offenders who are likely to commit more serious offenses. The empirical analysis shows that, in fact, the sentence length varied inversely with the general offense rate, with the likelihood of imprisonment, and with the length of postprison probation. The evidence also indicates that sentences vary with the individual's original record but not with the offender's age or race. With the exception of possible gender bias, the court's sentencing behavior was consistent with utilitarian principles.     

A test for carrion fly full siblings: a tool for detecting postmortem relocation of a corpse

We propose a genetic test for full sibship for a pair of carrion flies that could reveal the postmortem relocation of a corpse. A carrion fly larva is sometimes left behind when a corpse is moved. The discovery of full sibling larvae of approximately the same developmental stage at two locations would strongly suggest that a corpse was moved between those two sites. Distributions of pairwise comparisons of relatedness (R) coefficients were generated using amplified fragment length polymorphism profiles for nine samples of laboratory-generated full siblings as well as for a reference sample of nonfull sibling Phormia regina (Diptera: Calliphoridae). The mean relative R coefficient, a pairwise measure of the proportion of shared alleles, was 0.479 (±0.289 SD) for full siblings, close to the theoretical expectation of 0.5. A likelihood ratio (LR) test was based on observed distributions of R. R >0.55 corresponded to an LR >1000 favoring full sibship for that pair of individuals.

Are Public-Led Arts Incubating Programs a Double-Edged Sword? A Case Study of the Arts Council Korea’s Performing Arts Grant Program

A nation’s cultural policy is derived from its political and governance history, and its past practices. Taking the genealogical traits of South Korean cultural policies into account, the authors examine the contributions and risks of a public-led arts incubator program. One of the Arts Council Korea’s grant programs in the arts-incubating structure was involved with a public funding scandal of political intervention during the grant review process. Consequently, questions were raised about the current bureaucratic system for cultural policy. This article discusses the legitimacy of state intervention in the arts, and analyzes the case with relevant collected documents and interviews.
