Novel O‐propyl,S‐propyl,and N‐propyl substituted 1,4‐naphthoquinones and 1,4‐anthraquinones as potential fingermark development reagents for porous surfaces

Lawsone is a 2‐substituted‐1,4‐naphthoquinone derivative, which has been proposed as an alternative to the reagents currently used for fingermark detection on porous surfaces. 2‐substituted‐anthraquinones, which contain an additional conjugated benzene ring, have a similar chemical structure to that of lawsone. In this study, a new series of 2‐substituted‐1,4‐naphthoquinones and 2‐substituted‐1,4‐anthraquinones were synthesized and completely characterized by¹H NMR,¹³C NMR, IR, and HPLC‐TOF/MS analyses. All newly synthesized 2‐substituted‐1,4‐quinones were investigated for their ability to develop latent fingermarks on porous surfaces, and this ability was compared with that of lawsone. Each fingermark developed was graded using an established method; thus, quantitative data were attributed to each fingermark. It has been demonstrated that the 1,4 ‐ quinones react with amino acids present in latent fingermarks on selected paper surfaces to produce faint yellow‐orange impressions, which exhibit strong photoluminescence when illuminated with a forensic light source at 440 nm and observed through a red filter. None of the compounds caused background darkening. The results obtained were generally similar to those of lawsone, however, 8‐dibromo‐2‐(propylamino)naphthalene‐1,4‐dione and 5,8‐dibromo‐2‐(propylthio)naphthalene‐1,4‐dione yielded better results for copier paper and colored (blue) copier paper used in this analysis. To the best of our knowledge, this is the first study to examine the role of 1,4‐anthraquinone derivatives as potential fingermark development reagents. The results indicate that 1,4‐quinones have a potential to be used as reagents for enhancement of latent fingermarks.     

THROUGH A DIFFERENT LENS: USING FILM TO TEACH FAMILY LAW

This article discusses the aspects of narrative and character development that make films a useful tool to supplement classroom legal education. Moreover, utilizing film is particularly effective for learning and exploring the dynamics of human relationships at the center of family law cases. When designing a film and family law course instructors should seek to promote creative thinking, cultural competence, student exploration of bias and assumptions and best practices for attorneys based on the examples provided in the film. Films make the learning process more fun, but still provide substantial opportunities to broaden students' concept of the impact of law on family members.     

Private Security in Guatemala: Pathway to Its Proliferation

It has become common to explain the proliferation of private security services as causally determined by crime rates and institutional weakness. This article on the contrary argues that other explanatory factors need to be emphasised, especially for post‐war societies: institutional trajectories and political processes. The article first presents the present situation of commercial and non‐commercial private security services in Guatemala (private security companies as well as security neighbourhood committees). Against this background it reconstructs mechanisms and critical junctures through which the Guatemalan state had sourced out policing functions to the private sector during the war and traces the reinforcement of these mechanisms in post‐war society. It argues that the proliferation of private security services is an outcome of the reinforcing of an institutional pattern of public security displacement to the private sphere. The continuity of self‐defence and vigilante organisations thereby emerges as a stronger explanatory factor of the proliferation of private security services in post‐war societies than their self‐explained authorisation through high crime rates.     

Notes on expanding the concerns of peace research

This paper attempts to develop an approach to the problem of peace, the world order approach, and suggests some general directions for research in psychology intended to describe global conditions and to promote solutions to critical human problems. The author stresses the need for enlisting psychologists whose work focuses on the humanistic aspects of peaceful interactions.

The paper is divided into four sections. The first section presents the author's view of the current world situation; one that suggests expanded research and action in peace studies. The second section develops the concept of world order to complement the more restricted view of peace research that is often adopted. The third section develops the idea of constructing a global monitoring system designed to describe the global problem of peace. The final section proposes some broad directions for research in psychology that hopefully build upon previous and current efforts in the field.     

Sickle Cell Trait as a Contributory Cause of Death in Natural Disease

Sickle cell trait (SCT) affects 300 million people globally, and awareness is growing that SCT is not an entirely benign condition; however, most reported cases have been non‐natural deaths. Autopsy records from the Baylor University Medical Center (BUMC) in Dallas, Texas, contained seven natural deaths from January 2007 to October 2013 in which micro‐occlusive sickling was identified at autopsy and SCT confirmed by postmortem hemoglobin fractionation. Sickle crisis was never diagnosed clinically. These cases illustrate the importance of red cell morphology in autopsy material. When sickling is suspected, hemoglobin fractionation should be performed. If confirmed, SCT should be listed as an autopsy finding and the severity and distribution of sickling documented. Extensive micro‐occlusive sickling should be considered contributory to death; however, its relative importance depends on all facts of the case. Accurate reporting should facilitate further research and the development of evidence‐based preventative and supportive strategies for these patients.     

EXPANDING COLLABORATIVE DIVORCE THROUGH THE SOCIAL SCIENCES

Since collaborative law was first proposed, collaborative practitioners have expanded its concepts and methods as it has grown in acceptance by professionals and the public. This article addresses how collaborative law can further expand its theoretical and practical base by drawing from social science perspectives on negotiation, conflict resolution and third‐party interventions. It also explores how collaborative practice draws upon two prevailing models of negotiation, the strategic problem‐solving and the social‐psychological model, and demonstrates how tools from each model can be used at different points in a collaborative case's lifecycle.     

The Illegal Drug Industry,Violence and the Colombian Economy: A Department Level Analysis

Previous research on the Colombian illegal drug trade, which is generally qualitative in approach and focused on the national level, has concluded that the drug industry harms the economy. In order to test out this widespread claim, this article seeks to differentiate between the corrosive economic effects of Colombia's persistently high levels of generalised political violence and the specific consequences of the cocaine trade. It combines historical national level analysis with quantitative department analysis and identifies the economic effects of both paramilitary and guerrilla violence, thereby contributing to a closer examination of the impact of the drugs trade on the economy. The results reveal that paramilitary violence is related positively to exports but negatively to gross domestic product. Guerrilla violence, however, appears to harm exports but, surprisingly, not gross domestic product. Contrary to the conventional wisdom, coca cultivation does not have independent effects on exports or GDP, a conclusion which suggests that Colombia's economic problems stem more from political violence than from the drug trade in itself.
