Fingermark detection on non-porous and semi-porous surfaces using NaYF4:Er,Yb up-converter particles

This article describes the first use of an anti-Stokes material, or up-converter, for the development of latent fingermarks on a range of non-porous surfaces. Anti-Stokes materials can absorb long-wavelength light and emit light at a shorter wavelength. This property is unusual in both natural and artificial materials and so fingermark detection techniques based on anti-Stokes luminescence are potentially sensitive and selective. Latent fingermarks on luminescent and non-luminescent substrates, including Australian polymer banknotes (a well-known 'difficult' surface), were developed with sodium yttrium tetrafluoride doped with erbium and ytterbium (NaYF(4):Er,Yb) by dry powder, wet powder, and cyanoacrylate staining techniques. This study illustrates the potential of up-converter phosphors for the detection of latent fingermarks.     

Shifting perspectives: a confirmatory factor analysis of the working alliance inventory (short form) with high-risk violent offenders

The Working Alliance Inventory (WAI) is the most widely used measure of the therapeutic alliance. However, previous studies of the factor structure of the WAI have obtained disparate results. This study examined ratings from three rater perspectives (therapists, clients, and observers) in a rehabilitation program for high-risk violent prisoners with high PCL-psychopathy scores. The authors used confirmatory factor analysis with a short version of the WAI and examined one-, two-, and three-factor models. It was hypothesized that the context and client characteristics could alter the factor structure of the ratings. However, no differences were found in factor structure by perspective; the results from all rater perspectives suggested that a two-factor structure was the best fit for the data. Thus, we concluded that therapists, observers, and prisoners all saw the goals and task aspects of the therapeutic alliance as distinct from the bond component.     

FACTORS AFFECTING THE OUTCOME OF DIVORCE AND PATERNITY MEDIATIONS

Divorce mediation, an alternative to litigation when resolving disputes raised by the dissolution of a marriage or the separation of unmarried parents, has gained popularity over the past few decades. Yet, research is needed to better understand what processes make family mediation successful and for whom family mediation is successful. To study predictors of reaching agreement in family mediation, we gathered data from divorce and paternity cases at the Indiana University Maurer School of Law Viola J. Taliaferro Family and Children Mediation Clinic. Numerous factors, including history of intimate partner violence, father's reported concerns about participating in mediation, higher levels of father's income, number of mediation sessions, and attorney representation, were associated with lower rates of agreement. Associations between significant predictors are presented, as well as the combined impact of attorney representation and a history of relationship violence, which together significantly predicted lower agreement rates. The implications of these findings for understanding family mediation processes are considered.     

Thermal development of latent fingermarks on porous surfaces—Further observations and refinements

In a further study of the thermal development of fingermarks on paper and similar surfaces, it is demonstrated that direct contact heating of the substrate using coated or ceramic surfaces at temperatures in excess of 230 °C produces results superior to those obtained using hot air. Fingermarks can also be developed in this way on other cellulose-based substrates such as wood and cotton fabric, though ridge detail is difficult to obtain in the latter case. Fluorescence spectroscopy indicates that the phenomena observed during the thermal development of fingermarks can be reproduced simply by heating untreated white copy paper or filter paper, or these papers treated with solutions of sodium chloride or alanine. There is no evidence to suggest that the observed fluorescence of fingermarks heated on paper is due to a reaction of fingermark constituents on or with the paper. Instead, we maintain that the ridge contrast observed first as fluorescence, and later as brown charring, is simply an acceleration of the thermal degradation of the paper. Thermal degradation of cellulose, a major constituent of paper and wood, is known to give rise to a fluorescent product if sufficient oxygen is available [1], [2], [3], [4], [5]. However, the absence of atmospheric oxygen has only a slight effect on the thermal development of fingermarks, indicating that there is sufficient oxygen already present in paper to allow the formation of the fluorescent and charred products. In a depletion study comparing thermal development of fingermarks on paper with development using ninhydrin, the thermal technique was found to be as sensitive as ninhydrin for six out of seven donors. When thermal development was used in sequence with ninhydrin and DFO, it was found that only fingermarks that had been developed to the fluorescent stage (a few seconds of heating) could subsequently be developed with the other reagents. In the reverse sequence, no useful further development was noted for fingermarks that were treated thermally after having been developed with ninhydrin or DFO. Aged fingermarks, including marks from 1-year-old university examination papers were successfully developed using the thermal technique.     

Justification, perception of severity and harm, and criminalization of wife abuse in the Palestinian society

The purpose of this study was to examine the perceptions of Palestinian adults toward different dimensions of wife abuse. A cross-sectional survey, using a combination of self-administered questionnaires and interviews, was conducted among a systematic random sample of 624 adult Palestinian men and women from the West Bank and Gaza Strip (18 years or older). Study results indicated a strong tendency to justify wife beating in different situations, such as when the wife is perceived as having an affair with another man or as physically attacking her husband. Participants considered the following acts of husband's violence against wife as most severe: using a weapon (86%), having sex with the wife against her will (67%), and hitting her with his fist (57%). The majority of participants thought that wife beating should be considered a crime (82.3%). Traditional marital role expectations was the main significant predictor for all of the study criterion variables. Gender, place of residence, age, and marital status were significant predictors of some of the criterion variables.     

Assessing the Impact of the 1996 Thai Prostitution Law: A Study of Police Arrest Data

The purpose of this paper was to evaluate the impact of the Thai Prevention and Suppression of Prostitution Act of 1996 in ten geographical regions of the country. This paper also addresses law enforcement approaches in controlling prostitution. Data for prostitution arrests from 1995 to 1998 were obtained from official police sources (Statistics of Reported Crimes of Thailand). ARIMA intervention analysis was employed; revealing the arrest rates of prostitutes between pre- and post-enactment of the present Prostitution Act did not differ statistically within the regions except for Region 8 (Phuket). The paper reaches two general conclusions: (1) the 1996 Thai prostitution law did not significantly reduce the arrest rate for prostitution across the country; and (2) further consideration must be given to the idea of decriminalizing prostitution, which might allow for licensure, improving health and living conditions as well as potentially limiting exploitation and impact crimes associated with the prostitution industry.     

Group-Based Dominance and Opposition to Equality Correspond to Different Psychological Motives

Social Dominance Orientation, one of the most popular individual differences measures in the study of generalized prejudice, can be understood as having two components: Opposition to Equality (OEQ) and support for Group-Based Dominance (GBD). We consider these components in terms of system justification theory and social identity theory. We find that each component best explains different kinds of political views, consistent with the theory that they arise from different motivations. OEQ reflects system justification motives. It better predicts attitudes towards redistributive social policy, political conservatism, and a lack of humanitarian compassion for the disadvantaged. GBD reflects social identity motives. It is more associated with hostility toward outgroups and concerns about intergroup competition. GBD and OEQ have different personality and demographic correlates, exhibit distinctive relations with explicit and implicit attitudinal preferences, and differentially predict a variety of policy attitudes. Use of GBD and OEQ as separate constructs enriches the understanding of prejudice, policy attitudes, and political ideology.     

Evaluation of Stature Estimation from the Database for Forensic Anthropology*†

Abstract: Trotter and Gleser’s ( 1 - 3 ) stature equations, conventionally used to estimate stature, are not appropriate to use in the modern forensic context. In this study, stature is assessed with a modern (birth years after 1944) American sample (N = 242) derived from the National Institute of Justice Database for Forensic Anthropology in the United States and the Forensic Anthropology Databank. New stature formulae have been calculated using forensic stature (FSTAT) and a combined dataset of forensic, cadaver, and measured statures referred to as Any Stature (ASTAT). The new FSTAT‐based equations had an improved accuracy in Blacks with little improvement over Ousley’s ( 4 ) equations for Whites. ASTAT‐based equations performed equal to those of FSTAT equations and may be more appropriate, because they reflect both the variation in reported statures and in cadaver statures. It is essential to use not only equations based on forensic statures, but also equations based on modern samples.     

Necessary and Universal Truths about Law?

Prominent analytical jurisprudents assert that a theory of law consists of necessary, universal truths about the nature of law. This often‐repeated claim, which has not been systematically established, is critically examined in this essay. I begin with the distinction between natural kinds and social artifacts, drawing on the philosophy of society to show that necessity claims about law require a fundamental reworking of basic understandings of ontology and epistemology, which legal philosophers have not undertaken. I show law is a poor fit for a priori and a posteriori knowledge. I distinguish between universal application and universal truth, showing the former is sound while the latter is not. I expose the implications that follow from the initial selection of the central case of law, demonstrating that this choice must be justified, and I reveal two ways analytical jurisprudents shield their theories of law from refutation. This analysis raises significant doubts about the claim by analytical jurisprudents that they are identifying necessary, universal truths about the nature of law.
