Evaluating the Dimensionality and Invariance of ”Low Self-Control”

According to Gottfredson and Hirschi's (1990) A General Theory ofCrime, all illegal activity is the manifestation of a single underlyingcause. The authors argue that inadequate child-rearing causes individualsto develop a similar type of propensity for criminal and analogousbehavior. Gottfredson and Hirschi label this characteristiclow self-control. Six dimensions, which can be identified intheir theory, are suggested to comprise a final low self-controltrait. Further, low self-control is proposed to be an invariantcharacteristic (i.e., its form does not change with the age of theindividual or context in which the person resides). In this research, weevaluate these two propositions. First, the six dimensions are measured andused to determine if a multidimensional model can explain another commonfactor—low self-control—in two samples of individuals (fromdifferent locales) with dissimilar mean ages. Second, low self-control inboth samples is tested for invariance. We test the proposed invariance oflow self-control by examining if the parameter values in a model, which isreflective of Gottfredson and Hirschi's conceptualization of thecharacteristic, differ across the two samples of individuals. The resultssupport both of Gottfredson and Hirschi's propositions. Lowself-control does appear to be a multidimensional characteristic whosedimensions represent another common factor. Low self-control also appears tobe an invariant latent trait that members of these two samplespossess. These tests help to clarify Gottfredson and Hirschi'sconceptualization of low self-control.     

Government Hedging: Motivation, Implementation, and Evaluation

This article examines option hedging strategies that enable politicians to manage budgetary risk. While the theoretical risk management arguments are general, the simulation analysis considers the example of oil revenue risk in Texas, and estimates the costs and benefits of an option hedging program. To evaluate government option hedging strategies, the study develops a hedge quotient measure that compares the future value of realized revenues plus net option proceeds to the future value of expected revenue. The average hedge quotient is found to be lower for the option hedging strategy than for the unhedged position, illustrating the cost of an option hedging program. Nevertheless, option hedging effectively manages extreme downside risk and stops large budget deficits from occurring. Politicians may also like option hedging because it preserves the potential of realizing budget surpluses.     

Ethics and Public Sector Management: The Western Australian Experience

This paper considers two specific difficulties in developing a code of ethics for the public sector, the contested nature of the values to be expressed in a code of ethics and the organisational demands of a corporate managerialist framework which uses performance indicators. Using the example of the Western Australian public sector code of ethics, the authors conclude that a good strategy for developing a public sector code of ethics will recognise contestability, demonstrate philosophical integrity in the code, mesh the code with identified performance indicators and provide whistleblower protection. The strategy described provides a sufficient framework for any public sector bureaucracy to develop a justifiable code of ethics for use by public sector employees.     

Clinically Significant Trauma Symptoms and Behavioral Problems in a Community-based Sample of Children Exposed to Domestic Violence

This study assessed the associations of characteristics of domestic violence incidents with clinically significant levels of traumatic symptoms and behavioral problems in a socio-economically and ethnically mixed sample of 687 children participating in a community-service program for children witnessing violence. Study predictors included child/family demographic characteristics, type and chronicity of exposure, and child’s perceptions of control over the event and threat to personal safety. Outcomes consisted of traumatic symptoms and behavior problems. Results showed that perceived threat and control were associated with greater odds of clinically significant levels of several trauma symptoms (and behavior problems in the case of perceived threat) after adjusting for effects of demographic factors and violence characteristics. Child co-victimization increased odds of reaching clinically significant levels of traumatic symptoms compared to children who witnessed the event but were not victimized. Female sex and White ethnicity increased odds of specific trauma symptoms and behavior problems. Increasing age reduced odds of some trauma symptoms. Associations between predictors and one outcome measure did not generalize across the other outcome measure. Implications of study findings, and directions for future research are discussed.     

Gordon Tullock’s The Organization of Inquiry: A critical appraisal

The major themes of Gordon Tullock’s 1996 book The Organization of Inquiry are identified. Tullock’s treatment of the philosophy of science is criticized, as is his explanation for the backwardness of the social sciences relative to the natural sciences. The paper closes with a listing of some of Tullock’s proposals for the reform of science.     

Making the difference: Deleuze's difference and Derrida's différance

This paper seeks to explore the differences between Derrida's différance and Deleuze's difference. Derrida ‘s différance can be seen as based on a phenomenological theory of time, whereby the future is ‘prior’ to the past, and on a Hegelian theory of negation (but without final term or synthesis). Deleuze's, by contrast, relies on a Bergsonian theory of time as the actualization of virtualities, along with a positive and qualitative notion of difference derived from Nietzsche, Leibniz and Spinoza. The paper suggests some implications of these differences for Derrida's and Deleuze's approaches to criticism.
