An Experimental Analysis of Rent Seeking Under Varying Competitive Conditions

We test several predictions of Gradstein's(1995) rent seeking model using anexperimental design that includes avariable number of participants, costheterogeneity, and an entry fee. Consistentwith theoretical predictions, costheterogeneity and the entry fee decreasethe number of participants. Overall,participation is much lower than predicted. Also consistent with Gradstein's model, wefind that rent seeking expendituresincrease with the number of competitors anddecrease with the addition of an entry fee. Experimental results do not support theprediction that cost heterogeneitygenerally decreases expenditures in rentseeking contests.     

The BodeChecks solution: A high throughput analysis software combining GeneMapper ID, FSS-i, LIMS, and artificial intelligence

Combining key attributes of GeneMapper^® ID and FSS-i³ software packages with our internally created LIMS and some additional analytical programming has permitted us to increase quality checks on DNA profile data review while eliminating analysis time.     

Routine activities of delinquent and non-delinquent victims of violent crime

The link between criminal victimization and offending has become increasingly well documented in recent years. Unfortunately, the empirical and theoretical enmeshment of these variables makes it difficult to determine the effect of specific activities purely on victimization. This paper provides an examination of the effect of engaging in specific risky activities on the violent victimization experiences of delinquent and non-delinquent youth. Our results show that there are some modest differences in the effects of risky behaviors on the likelihood of violent victimization for delinquents and non-delinquents.     

Lawsuits against the police: Reasons for the proliferation of litigation in the past decade

More civil lawsuits have been filed against the police community in the past decade than at any other time in our history. This article traces the legal developments which have precipitated and even encouraged the increased amount of litigation in this area. Included is an examination of the deterioration of the sovereign immunity defense and the reasons for the vicarious liability of local uuits of government for the actions of individual police employees.     

Liquid/solid extraction on diatomaceous earth for drug analysis in postmortem blood

Absorption extraction on diatomaceous earth was examined and found to be compatible with typical postmortem blood specimens encountered in forensic toxicology. The effects of solvent, solvent volume, eluate flow rate, and pH on drug recovery and extract quality were investigated. It was concluded that the best method was not necessarily that with the highest recoveries, but that considerations of extract quality were also required. The optimized method was compared with a single-step liquid/liquid extraction method and found to be superior in terms of ease of operation, extract quality, and absolute recovery. The results indicated also that although useful for screening, quantitative methods using liquid/solid extraction may be prone to error.     

Enhancing Witness Memory with Focused Meditation and Eye-Closure: Assessing the Effects of Misinformation

Despite the decline in popularity of hypnosis as an investigative interviewing technique, this paper builds on previous research showing that some of the techniques employed in traditional hypnotic interviewing may still be useful in the development of simple, brief memory facilitation procedures for use by the police. Three experiments are described that investigate the effects of a short Focused Meditation with eye-closure technique in situations where participants are presented with misleading information. In the first study, which utilized a standard misinformation paradigm, a significant memory facilitation effect was shown with Focused Meditation, though the effect was not significant for eye-closure alone. There were no increases in errors when the Meditation and eye-closure procedures were used alone or in combination. The second experiment showed that a combined Focused Meditation with eye-closure technique reduced misinformation effects associated with fictitious events, and a third showed that the same technique reduced interrogative suggestibility effects as measured by the Gudjonsson Suggestibility Scale, whilst facilitating free recall memory. It is concluded that a Focused Meditation with eye-closure technique may potentially have applications in the field where brief alternatives to the Cognitive Interview are required.
