In a variety of settings, procedures that permit predecision input by those affected by the decision in question have been found to have positive effects on fairness judgments, independent of the favorability of the decision. Two major models of the psychology of procedural justice make contrary predictions about whether repeated negative outcomes attenuate such input effects. If such attenuation occurs, it would lessen the applicability of procedural justice findings to some real-world settings, such as organizations, where procedures often provide repeated negative outcomes. The present laboratory investigation examined the procedural and distributive fairness justments produced by high- and low-input performance evaluation procedures under conditions of repeated negative outcomes. Thirty-five three-person groups of male undergraduates participated in a three-round competition. Groups either were or were not allowed to specify the relative weights to be given to two criteria used in evaluating their performance. All groups received negative outcomes on each of the three rounds. A second experimental factor varied whether or not the group learned after losing the second round that it could not possibly win the third and final round of the competition. Measures of procedural and distributive fairness showed that the high-input procedure led to judgments of greater procedural and distributive fairness across all three rounds. The input-based enhancement of fairness occurred regardless of whether reward was possible. The implications of these findings for theories of procedural justice and for applications of procedural justice to organizational settings are discussed. 相似文献

The routine production of a cast of a shoe-print taken in soil provides information other than shoe size and gait. Material adhering to the surface of the cast represents the preservation of the moment of footprint impression. The analysis of the interface between the cast and soil is therefore a potentially lucrative source of information for forensic reconstruction. These principles are demonstrated with reference to a murder case which took place in the English Midlands. The cast of a footprint provided evidence of a two-way transfer of material between the sole of a boot and the soil of a recently ploughed field. Lumps of soil, which had dried on a boot, were deposited on the field as the footprints were made. Pollen analysis of these lumps of soil indicated that the perpetrator of the imprint had been standing recently in a nearby stream. Fibre analysis together with physical and chemical characteristics of the soil suggested a provenance for contamination of this mud prior to deposition of the footprint. Carbon/nitrogen ratios of the water taken from the cast showed that distilled water had been used thus excluding the possibility of contamination of the boot-soil interface. It was possible to reconstruct three phases of previous activity of the wearer of the boot prior to leaving the footprint in the field after the murder had taken place. This analysis shows the power of integrating different independent techniques in the analysis of hitherto unrecognised forensic materials. 相似文献

In this article, the authors draw on literatures outside sexual offending and make suggestions for working more positively and constructively with these offenders. Although the management of risk is a necessary feature of treatment, it needs to occur in conjunction with a strength-based approach. An exclusive focus on risk can lead to overly confrontational therapeutic encounters, a lack of rapport between offenders and clinicians, and fragmented and mechanistic treatment delivery. The authors suggest that the goals of sexual offender treatment should be the attainment of good lives, which is achieved by enhancing hope, increasing self-esteem, developing approach goals, and working collaboratively with the offenders. Examples are provided of how these targets may be met. When this is done within a therapeutic context where the treatment providers display empathy and warmth and are rewarding and directive, the authors suggest that treatment effects will be maximized. 相似文献

Quartz sand surface texture analysis has been automated for the first time for forensic application. The derived Basic Image Features (BIFs) provide computer-generated texture recognition from preexisting data sets. The technique was applied to two distinct classification problems; first, the ability of the system to discriminate between (quartz) sand grains with upturned plate features (indicative of eolian, global sand sea environments) and grains that do not exhibit these features. A success rate of grain classification of 98.8% was achieved. Second, to test the ability of the computer recognition system to identify specific energy levels of formation of the upturned plate surface texture features. Such recognition ability has to date been beyond manual geological interpretation. The discrimination performance was enhanced to an exact classification success rate of 81%. The enhanced potential for routine forensic investigation of the provenance of common quartz sand is indicated. 相似文献

This study reports an evaluation of the Drink-Impaired Drivers program in the English and Welsh probation service. Participants were adult male offenders who had been convicted of a drink-driving offence and were serving community sentences. The 1-year drink-drive reconviction rates were compared for offenders who completed the program, offenders who started but did not complete the program, and a comparison group who were not allocated to the program. At 1-year follow-up, there was no reconviction among offenders who had completed the program. Multivariate analysis showed that the noncompleters had a significantly higher rate of reconviction than the completers and comparison group. 相似文献

Non-destructive identification and subsequent age estimation of blood stains are significant steps in forensic casework. The latter can provide important information on the temporal aspects of a crime. As previously shown, visible spectroscopy of blood stains on white backgrounds can successfully be used for their identification and age estimation. The use of this technique however, is hampered by dark backgrounds. In the present study the feasibility to use near infrared (NIR) spectroscopy was evaluated for blood stain identification and age estimation on dark backgrounds. Using NIR reflectance spectroscopy, blood stains were distinguished from other substances with 100% sensitivity and 100% specificity. In addition, Partial Least Squares Regression analysis was applied to estimate the age of blood stains on colored backgrounds. The age of blood stains up to 1 month old was estimated successfully with a root mean squared error of prediction of 8.9%. These findings are an important step toward the practical implementation of blood stain identification and age estimation in forensic casework, where a large variety of backgrounds can be encountered. 相似文献
