Technology transfer of computer-based applications in law enforcement

As the use of computer-based technology has expanded in law enforcement, one of the central questions is how technology transfer has contributed to this development Drawing on a range of past and current research studies, the paper notes that the expectations of transfer have often exceeded the realities. Factors which both inhibit and enhance technology transfer in law enforcement are therefore outlined, and recommendations for the future are set forth.     

Validity Beliefs and Ideology Can Influence Legal Case Judgments Differently

Jurors sometimes enter a case both with prior beliefs about its likely validity and with more general ideologies that are relevant to the case. Although prior validity beliefs may serve as heuristics, directly biasing decisions when cognitive capacity is low, we hypothesized that ideology may bias systematic thought even when cognitive capacity is high. This experiment studied simulated individual juror decisions in a sex-discrimination case, measuring validity beliefs about such cases as well as feminist ideology, and exposing participants to 1 of 3 case versions under time pressure or no time pressure. Validity beliefs had a direct, heuristic impact on judgment only under time pressure. However, feminist ideology had a mediated influence on judgment via valenced thoughts about the evidence, even under no time pressure. Also, people with initially proplaintiff beliefs judged a woman's sex-discrimination suit more negatively than did prodefendants if the evidence was weak. The results suggest that when jurors can fully process information, validity expectancies might backfire if not supported by case evidence, but ideology can have a more pervasive influence on the decision-making process.     

Chest deflection tolerance to blunt anterior loading is sensitive to age but not load distribution

Ninety-three human cadaver tests are used in the development of thoracic injury risk functions with consideration of age and restraint condition. Linear logistic regression models are developed with the set of potential predictors including the maximum chest deflection, the age of the cadaver at death, gender, and the loading condition on the anterior thorax: blunt hub (41 tests), seat belt (26 tests), air bag (12 tests), and combined belt-and-bag (14 tests). Predicted outcomes were the probability of any rib fractures (onset of injury) and the probability of greater than six rib fractures (severe injury). The analysis shows that the injury risk function was not dependent on the loading condition, but was strongly dependent on age. A significant injury risk model with good ability to discriminate injury from non-injury tests (P < 0.0001, chi-square = 21.49, area under receiver operator characteristic curve (ROC) = 0.867, Kruskal's Gamma = 0.732) is presented using only maximum chest deflection and cadaver age as predictors of injury risk. The 50% risk of any rib fractures is found to occur at 35% chest deflection for a 30-year-old, but at 13% deflection for a 70-year-old. The 50% risk of severe injury is shown to occur at 33% chest deflection for a 70-year-old, but at 43% for a 30-year-old.     

When Policies Undo Themselves: Self‐Undermining Feedback as a Source of Policy Change

Most studies of policy feedback have focused on processes of self‐reinforcement through which programs bolster their own bases of political support and endure or expand over time. This article develops a theoretical framework for identifying feedback mechanisms through which policies can become self‐undermining over time, increasing the likelihood of a major change in policy orientation. We conceptualize and illustrate three types of self‐undermining feedback mechanisms that we expect to operate in democratic politics: the emergence of unanticipated losses for mobilized social interests, interactions between strategic elites and loss‐averse voters, and expansions of the menu of policy alternatives. We also advance hypotheses about the conditions under which each mechanism is likeliest to unfold. In illuminating endogenous sources of policy change, the analysis builds on efforts by both historically oriented and rationalist scholars to understand how institutions change and seeks to expand political scientists’ theoretical toolkit for explaining policy development over time.     

Sex differences, parental attachment, and juvenile delinquency

This study examined the relationship between parental attachment and delinquent behavior among adolescents between the ages of 13 and 18. 133 subjects completed self-report questionnaire packets, which included a demographic survey, an attachment inventory (assessing parental attachment and attachment to the father and mother separately), and a delinquency questionnaire. The relationship between sex, delinquency level, and attachment score was statistically tested using a multivariate analysis of variance. Results indicated a significant relationship between delinquency level and parental attachment, attachment to father, and attachment to mother, suggesting that the more attached adolescents are to their parents, the less delinquent they are. The effects of sex on attachment were not significant, nor were the effects of sex by delinquency on attachment. Mean attachment scores to the mother were not significantly higher than mean attachment scores to the father and females reported far less criminal activity, but more delinquent activity, than did males. Implications of the findings are discussed.     

Property tax administration in developing countries: Alternatives for land registration and cadastral mapping

The property tax is a widely used fiscal tool in many developing countries. However, property tax evasion and underpayment are common. This fact underscores the need for governments to administer the property tax effectively if they are to maximize revenue for development. A workable system of land registration and cadastral mapping is one of the principal prerequisites for efficient administration of the property tax. This paper examines alternative methods of land registration and cadastral mapping appropriate for governments in developing countries. The registration of deeds and titles is discussed, as are the most appropriate means for their implementation. Similarly, the different types of cadastral systems, fiscal, legal and multi-purpose, and the survey methods necessary for their implementation, are reviewed.
