Aviation security and terrorism: a review of the economic issues

Following the terrorist attacks on September 11, 2001, the passage of the Aviation and Transportation Act mandated a substantial increase in resources devoted to aviation security. This paper summarizes the specific changes stemming from this legislation. In addition, the paper examines the economic issues underlying the regulation and provision of aviation security. The fact that security at one airport can affect the well being of those at other airports and elsewhere, an example of a network externality (spillover), provides an economic justification for governmental involvement in aviation security. A fundamental question is whether the federal role should be restricted to setting and monitoring security standards or whether the role should also include the financing and implementation of security. A controversial change is that the federal government has assumed responsibility from the airlines and airports for the actual provision of aviation security. Proponents of this change argue that, relative to private provision, public provision reduces the incentives to reduce quality through cost reductions. On the other hand, a public agency might not provide security services efficiently because it can operate in a more-or-less monopolistic way. Furthermore, a public agency might provide an excessive amount of security and incur unnecessary expenses because it is likely to be judged on its security record and not on all the attributes encompassed by air transportation services for consumers. Thus, economic theory does not provide a clear answer to what is likely to be a continuing source of controversy - the appropriate scope of governmental involvement in aviation security.Economic conditions ; War - Economic aspects

Examining Strain in a School Context

General strain theory has accumulated a considerable amount of empirical support. Many of these assessments have tested the direct relationship that strain has on crime and delinquency. The research presented here examines the relationship between schools and delinquency within a general strain theory perspective. More specifically, this research examines how schools can not only act as a source of an individual\u27s strain and subsequent delinquency but also be a source for mediating or coping with strain and minimizing delinquency. To test the relationship between schools and delinquency, data from the National Educational Longitudinal Survey (NELS:88) are analyzed in a model of general strain that specifies sources of school-based strain and sources of school-based mechanisms for controlling strain

An Exploratory Study of Confidence in Policing in India

The November 2008 terrorist attack in Mumbai has brought a great deal of attention upon policing in India. In light of the proposed overhauls in policing in India, community policing initiatives have become increasingly utilized across the sub-continent. There remains, however, the important question as to how successful these initiatives can be in a country with such ethnic, class and religious diversity. The study undertaken here is an exploratory examination as to which variables are most closely associated with police confidence. The data for the study drew upon the India Human Development Study 2004-2005 of 41,554 households across India. The results of this study suggest that the variables most significantly associated with confidence in police (human/social capital, religion/caste) are best examined at the state level due to the degree of variance across states. Possible implications for community policing policies in India are also considered

On Toroidal Horizons in Binary Black Hole Inspirals

We examine the structure of the event horizon for numerical simulations of two black holes that begin in a quasicircular orbit, inspiral, and finally merge. We find that the spatial cross section of the merged event horizon has spherical topology (to the limit of our resolution), despite the expectation that generic binary black hole mergers in the absence of symmetries should result in an event horizon that briefly has a toroidal cross section. Using insight gained from our numerical simulations, we investigate how the choice of time slicing affects both the spatial cross section of the event horizon and the locus of points at which generators of the event horizon cross. To ensure the robustness of our conclusions, our results are checked at multiple numerical resolutions. 3D visualization data for these resolutions are available for public access online. We find that the structure of the horizon generators in our simulations is consistent with expectations, and the lack of toroidal horizons in our simulations is due to our choice of time slicing.Comment: Submitted to Phys.

Clinical Social Work and the Biomedical Industrial Complex

This article examines how the biomedical industrial complex has ensnared social work within a foreign conceptual and practice model that distracts clinical social workers from the special assistance that they can provide for people with mental distress and misbehavior. We discuss: (1) social work\u27s assimilation of psychiatric perspectives and practices during its pursuit of professional status; (2) the persistence of psychiatric hospitalization despite its coercive methods, high cost, and doubtful efficacy; (3) the increasing reliance on the Diagnostic and Statistical Manual of Mental Disorders, despite its widely acknowledged scientific frailty; and (4) the questionable contributions of psychoactive drugs to clinical mental health outcomes and their vast profits for the pharmaceutical industry, using antipsychotic drugs as a case example. We review a number of promising social work interventions overshadowed by the biomedical approach. We urge social work and other helping professions to exercise intellectual independence from the reigning paternalistic drug-centered biomedical ideology in mental health and to rededicate themselves to the supportive, educative, and problem-solving methods unique to their disciplines
