Social science research and experimentation in Australian criminal proceedings: prejudicial pre-trial publicity and psychological research

Using the decision of Barr J in Attorney-General (NSW) v John Fairfax Publications [1999] NSWSC 318, the authors analyse the need for external validity and relevance in social science evidence adduced in the courts. They argue in favour of the rigour employed within Barr J's judgment and contend that a constructive legacy of the decision should be a greater sensitisation on the part of researchers to the kinds of factors that can distance experimental scenarios from curial contexts to a point where generalisations from the former become strained and even spurious. A number of these considerations have the potential to be addressed to a significant extent by improved methodologies. However, the authors warn against an excess of purist fervour in demanding complete comparability of scenarios, lest the fruits of social science be denied to the courts and decision-making be adversely affected by the absence of expert insights falling short of complete replication of conditions between experiments and forensic reality.     

Truth,Lies, and Videotape: An Investigation of the Ability of Federal Parole Officers to Detect Deception

The ability of a group of Canadian federal parole officers to detect deception was investigated over the course of 2 days of lie detection training. On the first day of training, 32 officers judged the honesty of 12 (6 true, 6 fabricated) videotaped speakers describing personal experiences, half of which were judged before and half judged after training. On the second day, 5 weeks later, 20 of the original participants judged the honesty of another 12 videotapes (again, 6 pre- and 6 posttraining). To isolate factors relating to detection accuracy, three groups of undergraduate participants made judgments on the same 24 videotapes: (1) a feedback group, which received feedback on accuracy following each judgment, (2) a feedback + cue information group, which was given feedback and information on empirically based cues to deception, and (3) a control group, which did not receive feedback or cue information. Results indicated that at baseline all groups performed at or below chance levels. However, overall, all experimental groups (including the parole officers) became significantly better at detecting deception than the control group. By the final set of judgments, the parole officers were significantly more accurate (M = 76.7%) than their baseline performance (M = 40.4%) as well as significantly more accurate than the control group (M = 62.5%). The results indicate that detecting deceit is difficult, but training and feedback can enhance detection skills.     

‘First wave’ feminism in nineteenth-century France: Class, family and religion

The history of ‘first wave’ feminism in France raises several questions of relevance to the contemporary women's movement. Organized French feminism began during the struggle to replace a Catholic monarchy with a rationalistic, republican form of government. Because of the allegiance of most Frenchwomen to the church, however, even the republican and socialist supporters of feminist reform in educational institutions and in civil rights opposed political participation by women. Feminists, who themselves emphasized reforms in family law and economic opportunities, formed numerous organizations, published journals and held national and international meetings, but remained less a movement than a mosaic of leaders and groups divided by class, religion and personal rivalry. More importantly, they were estranged from the majority of Frenchwomen by questions pertaining to the relationship of women to the traditional patriarchal family, which continued to play a dominant role in the religious, economic and social life of the country. Internal conflict developed over protective legislation and women's ‘right to work’, while external opposition centered about the politically reactionary potential of religious women, and the alleged ‘anti-patriotic’ individualism of those who rejected motherhood as the ‘natural vocation’ and only career of women. By pitting feminism against a particular form of the family, antifeminists obscured the reality of women's oppression and succeeded in alienating the potential support for feminism of most Frenchwomen.     

Correlates of self-concept among black early adolescents

This study examines the self-concept of Black eighth-grade students from the Midwest in relation to Black acceptance, social intimacy, locus of control, and sex-role type. Twenty-eight students high in self-concept were compared with 31 students whose self-concept was low. As predicted, the high self-concept group scored higher than the low self-concept group in intimacy, internality, and acceptance of black identity. As also predicted, the high self-concept group had a significantly greater number of adolescents with masculine and androgynous sex roles than the low self-concept group; Black females with high self-concepts included a larger proportion of individuals with androgynous sex roles than low self-concept females. However, the prediction that high self-concept males would have a larger proportion of masculine sex roles than low self-concept males was not supported. The difficult situation of the low self-concept adolescents is discussed, along with the implications for intervention.On clinic internship at Smolian Psychiatric Clinic in Birmingham, Alabama. Major interests are clinical psychology and Black identity.Received Ph.D. in social psychology from the University of Colorado. Major interests are the development of intimacy and identity in adolescence and young adulthood.

The quantification of fingerprint quality using a relative contrast index

Research into fingermark enhancement techniques has traditionally used visual comparisons and qualitative methods to assess their effectiveness based on the quality of the developed fingermark. However, with increasing research into the optimisation of these techniques the need for a quantitative evaluative method has arisen. Parameters for acceptable fingerprint quality are not well defined and generally encompass clear, sharp edges and high levels of contrast between the fingermark ridges and background material. Using these current parameters, a conclusive measurement of fingerprint quality and thus the effectiveness of development techniques cannot be achieved.This study presents a model through which an aspect of fingerprint quality can be objectively and impartially measured based on a relative contrast index, constructed through measuring the reflective intensity of the fingermark ridges against the background material. Using a fibre-optic spectrophotometer attached to a microscope with axial illumination, the intensity counts of the ridge detail and background material were measured and a logarithmic contrast index constructed. The microscope and spectrophotometer parameters were experimentally tested using a standard colour resolution chart with known reflective properties. The protocol was successfully applied to four sample groups: black inked fingerprints on white paper; latent fingermarks on white paper developed separately with ninhydrin and physical developer; and fingermarks in blood deposited on white tiles and enhanced with amido black. The contrast indices obtained quantitatively reflect the level of contrast and provide an indication of fingerprint quality through a numerical representation rather than previous qualitative methods. It has been suggested that the proposed method of fingerprint quantification may be viable for application in the forensic research arena as it allows the definitive measurement of contrast to aid the evaluation of fingermark detection and enhancement techniques.
