A multidimensional scaling analysis of the Hare PCL-R: Unfolding the structure of psychopathy

Abstract

Recent studies examining the Psychopathy Checklist – Revised (PCL-R) have argued for a range of factorial solutions to describe and explain the dimensions of psychopathy. This study details an empirical analysis of North American PCL-R data for 4630 male offenders, using multidimensional scaling (MDS) as a non-linear alternative to factor analysis. The emergent structure of Hare's psychopathy psychometric can be interpreted in more than one way and at different levels of specificity. The multidimensional scalograms reveal a set of facets consistent with the two- and four-factor solutions that emerge from the same data. Equally the structure of the PCL-R can be interpreted through personality theory as a set of core traits and behavioural manifestations, consistent with an evolutionary basis for psychopathic tendencies. These analyses provide support for a multidimensional structure within the PCL-R, and suggest that psychopathy can be viewed as an extreme variant of multiple dimensions of personality.     

Resettle: a significant new step in an emerging pathway that manages risk and addresses need in high-risk personality disordered offenders on their release into the community

Abstract

This paper will describe an innovative UK service development, Resettle, which is designed to address the needs and risks of personality disordered offenders who are released into the community from prison and whose high risks of harm and re-offending are linked to their personality disorder (PD). All the cases worked with are subject to Multi-Agency Public Protection Arrangements (MAPPA). This non-residential, intensive community-based service is nationally funded jointly by the Department of Health and Ministry of Justice, originally as part of the Dangerous and Severe Personality Disorder (DSPD) programme for high-risk offenders. Resettle became operational in 2008. It is currently being independently evaluated via a randomised control trial that is due to complete in March 2013. Formal outcome data are, therefore, not yet available, however, the developing model of intervention based on experience and learning to date is described alongside the policy and service context for this area of work.     

Information Conduits or Content Developers? Determining Whether News Portals Should Enjoy Blanket Immunity from Defamation Suits

News portals should be held to the same standard of liability for defamation as other news media. Internet service providers (ISPs) enjoy blanket immunity from liability for defamation under Section 230 of the Communications Decency Act, while information content providers (ICPs) might not. Some courts have indicated, however, that a defendant who participates in developing third-party content should be classified as an ICP and thus be held liable. Confusion over the difference between an ISP and an ICP is applied to the case of news portals. This study investigates to what extent news portals should enjoy immunity from liability for defamation. To determine a news portal's exposure to liability, a continuum of involvement is proposed as a standard in which liability is based on a defendant's actions and not on the medium employed. A defendant's involvement with third-party content can be classified under the four levels of the continuum, which can guide courts in deciding whether a defendant is liable. Congress should amend Section 230 to incorporate the continuum and allow courts discretion in determining whether a defendant is immune from liability.     

Committee Property Rights,Executive Dominance,and Political Parties in Latin American Legislatures

Motivated by theories of congressional committees in the US context, and building on the growing body of work focusing on the institutional features of legislatures in Latin American presidential systems, this paper explores two previously overlooked aspects of committee politics. Using comparative data from three Latin American countries, it examines the strategic and jurisdictional dynamics in which chamber leaders assign bills to committees and then investigate the factors affecting presidential and partisan success within committees. In general, the authors find that committees have strong property rights and that characteristics of both bills and bill initiators strongly influence the survival of legislation in committee. The results shed light on the effects of institutional design on the policy process in presidential systems.

Towards a postmodern science of language

This article outlines the terms and rationale for a ‘postmodern’ science of language, and illustrates it with reference to a single text: President George Bush's speech to Congress in the wake of September 11. It first addresses the issue of whether and how students of language can or should draw on scientific concepts and theories, and where the acute anxieties on this topic come from. It then proposes that a new stage in science needs to be recognised that changes the terms of the relations between science and the humanities. ‘Postmodern’ forms of science accept and work with the uncertainty, unpredictability, ambiguity and contradiction that characterise the phenomena of language and society in every era, and is especially marked in the present ‘postmodern condition’. The article then briefly explains key concepts from this body of scientific work: Poincare´'s Three Body Analysis, Prigogine's far-from-equilibrium analysis, Zadeh's fuzzy logic, Mandelbrot's fractals, Heisenberg's Uncertainty Principle, and Lorenz's Butterfly Effect.

Legacy of the Housing Act of 1949: The Past,Present, and Future of Federal Housing and Urban Policy

Abstract

This article summarizes a special issue of Housing Policy Debate, which commemorates the 50th anniversary of the Housing Act of 1949. The act is best remembered for its declaration that every American deserves a “decent home and a suitable living environment.” The articles in this collection offer varying perspectives on how this act helped shape the postwar metropolis. The authors—urban planners, historians, and public officials—each consider a different part of the legacy.

The first three articles deal primarily with the act's creation and social and political ramifications, while the next three look at how Titles I, II, and III have influenced the past 50 years of housing and urban policy. The record of the Housing Act of 1949 is mixed, and so are its lessons. There remains an ongoing struggle to find the right mix of housing support to reach the goals first expressed in this landmark legislation.     

From seaside to Southside: New urbanism's quest to save the inner city

Abstract

In this article, we use a random sample of urban community development corporations (CDCs) to determine whether distinct types exist and, if so, to estimate their prevalence in the industry. The typical urban CDC has a diversified portfolio of economic and social development activities, including community organizing, and is likely to have a housing development program, although not necessarily a large one because relatively few are high producers.

Large‐scale housing producers, defined in the study as having produced at least 500 units during the previous 10 years, comprise 18 percent of CDCs. A large organizational capacity, an affiliation with national intermediaries, the training of staff and the adoption of computers, the length of executive directors’ tenure, and the share of funding devoted to housing programs are the most important factors increasing the odds that a CDC will belong to the group of high producers.
