Reflections on the implications of the Vietnam Caucus

Abstract

It is revealing that a Vietnam Caucus held in March 1968 should end its meeting by beginning an evaluation of the professional “conscience” of Asian scholars. That it took this war to raise the latent problems in the profession is itself a depressing commentary on the state of the field. But the desire on the part of some individuals to create a nationwide inter-university student-faculty Committee of Concerned Asian Scholars to pose and then seek to resolve these problems fulfills one of the organizers' hopes.     

Reformas electorales y coherencia ideológica de los partidos políticos en Colombia, 1986-2013

This article sets out changes which the Colombian party system experienced throughout the last two decades. It focuses on the topics, ideology and party divisions present in a representative sample of the last four legislatures’ congress members. This study is based on factorial and discriminate analyses, making use of the Latin American Parliamentarian Elites database. This article holds that the 2003 political reform had a positive effect on Colombian parties’ and social movements’ ideological coherence within Congress. Electoral reforms are also discussed in the light of these findings.     

Human rights, ethical principles, and standards in forensic psychology

Human rights create a protective zone around persons and allow them the opportunity to further their valued personal projects without interference from others. This article considers the relationship between human rights and the general ethical principles and standards contained in the American Psychological Association's (APA's) code of ethics as applied to the forensic domain. First, it analyzes the concept of human rights, their structure, and their justification. Second, it briefly describes the APA's most recent code of ethics and the principles and standards that compose it. Third, it concludes by explicitly examining the relationship between the present human rights model and the APA's code, demonstrating how it is able to provide an additional ethical resource for forensic practitioners in their clinical work and so deepen their ethical sensibilities and decision making. Finally, the article presents a case study and discusses the human rights issues confronting practitioners inherent in such situations.     

Effectiveness of pupil diameter in a probable‐lie comparison question test for deception

Purpose. There were three objectives of this study: (1) To assess the possibility of using pupil diameter as an index of deception in the context of a comparison question polygraph test. (2) To determine if pupil diameter would make a significant contribution to an optimal multivariate classification equation in combination with the traditional predictor variables used in field polygraph practice. (3) We explored the possibility of replacing one or more of the traditional predictor variables with pupil diameter. Methods. We used a laboratory mock crime experiment with 24 participants, half of whom stole $20 (US) from a secretary's purse. Participants were tested with a comparison question test modelled after standard field practice. Physiological measures were taken with laboratory quality instrumentation. Features were extracted from the physiological measures. Those features were subjected to a number of different statistical analyses. Results. Innocent participants showed larger increases in pupil diameter in response to probable‐lie questions than to relevant questions. Guilty participants did not show differential responding to the question types. The additional of pupil diameter to a multivariate classification model approached, but did not reach significance. Subsequent analyses suggest that pupil diameter might be used to replace the traditional relative blood pressure measure. Conclusions. Pupil diameter was found to be a significant predictor variable for deception. Pupil diameter may be a possible replacement for the traditional relative blood pressure measure. Additional research to explore that possibility would seem to be warranted.     

Forensic utility of the mitochondrial hypervariable region 1 of domestic dogs, in conjunction with breed and geographic information

The 608-bp hypervariable region 1 (HV1) sequences from 36 local dogs were analyzed to characterize the population genetic structure of canid mitochondrial DNA (mtDNA). Sixteen haplotypes were identified. A 417-bp segment of this sequence was compared with GenBank sequences from a geographically representative sample of 201 dogs, two coyotes, and two wolves. Sixty-six haplotypes were identified including 62 found only in domestic dogs. Fourteen of these correspond to the 16 local haplotypes and were among the most frequent haplotypes. The local sample was judged to be representative of the much broader geographic sample. No correlation was observed between local haplotypes and the owner's characterization of dog breed. A 60-bp variation "hotspot" within the canid HV1 was identified as a potentially valuable molecular tool, particularly for assaying limited or degraded DNA samples.     

Recovery of DNA for forensic analysis from lip cosmetics.

To obtain a reference DNA profile from a missing person, we analyzed a variety of personal effects, including two lip cosmetics, both of which gave full DNA profiles. Further investigations were undertaken to explore this previously unreported source of DNA. We have tested a range of brands and types of lip cosmetics. Our studies have revealed that lip cosmetics are an excellent source of DNA, with almost 80% of samples giving a result. However, artifacts are frequently observed in the DNA profiles when Chelex is used for the DNA extraction and additional DNA purification procedures are required to ensure that an accurate DNA profile is obtained.
