The Effect of Light Exposure on the Degradation of Latent Fingerprints on Brass Surfaces: The Use of Silver Electroless Deposition as a Visualization Technique

We have studied the degradation of sebaceous fingerprints on brass surfaces using silver electroless deposition (SED) as a visualization technique. We have stored fingerprints on brass squares either (i) in a locked dark cupboard or (ii) in glass‐filtered natural daylight for periods of 3 h, 24 h, 1 week, 3 weeks, and 6 weeks. We find that fingerprints on brass surfaces degrade much more rapidly when kept in the light than they do under dark conditions with a much higher proportion of high‐quality prints found after 3 or 6 weeks of aging when stored in the dark. This process is more marked than for similar fingerprints on black PVC surfaces. Identifiable prints can be achieved on brass surfaces using both SED and cyanoacrylate fuming (CFM). SED is quick and straightforward to perform. CFM is more time‐consuming but is versatile and can be applied to a wider range of metal surfaces than SED, for example brass surfaces which have been coated by a lacquer.     

The stationarity of inflation in Croatia: anti-inflation stabilization program and the change in persistence

This study examines the impact of the anti-inflation stabilization policies on the behavior of inflation in Croatia in the early 1990s and through the subsequent post-stabilization period using fractional integration techniques. Indeed, the implementation of the stabilization program in October 1993 brought immediate deflation with a relative high degree of inflation stability in the post-stabilization period. With allowance for a structural break corresponding to the stabilization program in October 1993, the degree of persistence was substantially reduced with the fractional differencing parameter being positive but close to zero in the post-stabilization period.     

Unpacking the Diaspora Channel in New Democracies: When Do Migrants Act Politically Back Home?

Migrant influence on politics back home has arguably become broader and deeper in the wake of a widespread convergence between out-migration and democratization. This article seeks to identify the structural conditions under which migrants from post-1980 democracies are likely to activate the “diaspora channel” of political influence back home. Specifically, I identify, explain, and code two sets of incentives likely to induce migrants to engage in home-country politics from abroad: (1) socioeconomic incentives generated by cross-border linkages and migrant characteristics likely to predispose them toward broader forms of transnational engagement and (2) political incentives generated by diaspora politicization and formal access to the political process in the home country. I score these incentives in 40 developing countries and then generate hypotheses about the degree to which migrants from these countries are likely to activate the diaspora channel through participation in home-country elections, lobbying for policy changes by the home-country government, or transnational coproduction.     

Do PCL-R scores from state or defense experts best predict future misconduct among civilly committed sex offenders?

In a recent study of sex offender civil commitment proceedings, Murrie et al. (Psychol Public Policy Law 15:19-53, 2009) found that state-retained experts consistently assigned higher PCL-R total scores than defense-retained experts for the same offenders (Cohen's d > .83). This finding raises an important question about the validity of these discrepant scores: Which type of score, state or defense evaluator, provides the most useful information about risk? We examined the ability of PCL-R total scores from state and defense evaluators to predict future misconduct among civilly committed sex offenders (N = 38). For comparison, we also examined predictive validity when two state experts evaluated the same offender (N = 32). Agreement between evaluators was low for cases with opposing experts (ICCA,1 = .43 to .52) and for cases with two state experts (ICCA,1 = .40). Nevertheless, scores from state and defense experts demonstrated similar levels of predictive validity (AUC values in the .70 range), although scores from different types of state evaluators (corrections-contracted vs. prosecution-retained) did not. The finding of mean differences between opposing evaluator scores, but similar levels of predictive validity, suggests that scores from opposing experts in SVP cases may need to be interpreted differently depending on who assigned them. Findings have important implications for understanding how rater disagreement may relate to predictive validity.     

America’s most wanted criminals: comparing cybercriminals and traditional criminals

Reports of cybercrime have escalated over the past decade. While these crimes have increased, our understanding about the dynamics surrounding cyber offenders has not kept pace. Few studies have considered the characteristics of serious cyber criminals in comparison to other types of criminals. To fill this void in the literature, we examine a sample of cybercriminals appearing on the FBIs Most Wanted List and compare the characteristics of these offenders to other most wanted offenders. Results suggest that the most wanted cyber offenders are similar to other offenders in that it is a male-dominated offense category, but they are different from other offenders in that they are younger and more likely to exhibit certain types of physical and lifestyle characteristics. Implications for policy and future research are provided.
