    Serious violent offenders : developing a risk assessment framework

    Get PDF
    In order to establish a complementary language of risk across all agencies, it is recommended that the Scottish Government and the Risk Management Authority actively disseminate MAPPA guidance through the RMA's specialist training programme and through the development of protocols and memoranda of agreement. Prior to a violent offender framework being implemented, an audit of existing numbers, staffing, budgetary and other resources should be undertaken across the Community Justice Authorities to ascertain projected needs

    Identity, Discourse, and Rehabilitation in Parole Hearings in the United States

    Get PDF
    Research on parole in the United States has primarily followed a deterministic approach, favoring an examination of variables contributing to release. However, a great deal of prior research neglects a central aspect of the parole process: mainly the hearing. Adopting an ethnographically informed conversation analytic approach, this article addresses one tactic offenders utilize to appeal to a state parole board for release– claiming rehabilitated status. Offenders appealing for parole attempt to establish, in a performative space, their identity as rehabilitated. More globally, this article addresses how individual manage, assert, and negotiate identity in the course of interaction. The achievement of “rehabilitation” is substantiated when it results in early release from prison

    Policy Challenges for Collaborative Forestry: A Summary of Previous Findings and Suggestions

    Get PDF
    After several years of effort, many collaborative and community-based forestry groups that formed in the 1990s are still struggling to implement their land management projects. The combined impact of several factors, including legal challenges, funding problems, agency history, bureaucratic processes, and poor internal communication, seems to conspire against collaborative solutions for today's land management challenges. Several efforts have been made in recent years to identify barriers to collaboration and to identify various solutions to these complicated public resource issues. As part of this chain of examinations, the Ecological Restoration Institute, in cooperation with the Pinchot Institute, the Society of American Foresters, and American Forests, has organized a 2-day workshop to clarify policy and procedural factors that hinder collaborative forestry efforts and suggest policy changes to address those factors. This document, which summarizes the findings and suggestions from previous workshops and policy analyses, has been prepared for participants in the September 2003 workshop. In order to facilitate discussion, this document is divided into three sections. The first section reviews legal and regulatory problems faced by collaborative forestry groups. The second lists various funding challenges faced by agency partners and collaborators. The third section summarizes barriers to collaboration that have been attributed to Forest Service culture and practices. Each problem statement is followed by an explanatory discussion from the literature, and, where available, suggestions for policy changes that could alleviate the problem

    Response and Recovery of the Comanche Carbonate Platform Surrounding Multiple Cretaceous Oceanic Anoxic Events, Northern Gulf of Mexico

    Get PDF
    The ubiquity of carbonate platforms throughout the Cretaceous Period is recognized as a product of high eustatic sea-level and a distinct climatic optimum induced by rapid sea-floor spreading and elevated levels of atmospheric carbon-dioxide. Notably, a series of global oceanic anoxic events (OAEs) punctuate this time-interval and mark periods of significantly reduced free oxygen in the world's oceans. The best records of these events are often from one-dimensional shelf or basin sections where only abrupt shifts between oxygenated carbonates and anoxic shales are recorded. The Comanche Platform of central Texas provides a unique opportunity to study these events within a well-constrained stratigraphic framework in which their up-dip and down-dip sedimentologic effects can be observed and the recovery of the platform to equilibrium states can be timed and understood. Stable isotope data from whole cores in middle Hauterivian through lower Campanian mixed carbonate-siliciclastic strata are used to construct a 52-myr carbon isotope reference profile for the northern Gulf of Mexico. Correlation of this composite curve to numerous global reference profiles permits identification of several anoxic events and allows their impact on platform architecture and fades distribution to be documented. Oceanic anoxic events la, 1b, 1d, and 2 occurred immediately before, after, or during shale deposition in the Pine Island Member, Bexar Member, Del Rio Formation, and Eagle Ford Group, respectively. Oceanic anoxic event 3 corresponds to deposition of the Austin Chalk Group. Platform drowning on three occasions more closely coincided with globally recognized anoxic sub-events such as the Fallot, Albian-Cenomanian, and Mid-Cenomanian events. This illustrates that the specific anoxic event most affecting a given carbonate platform varied globally as a function of regional oceanographic circumstances. Using chemo- and sequence-stratigraphic observations, a four-stage model is proposed to describe the changing fades patterns, fauna, sedimentation accumulation rates, platform architectures, and relative sea-level trends of transgressive-regressive composite sequences that developed in response to global carbon-cycle perturbations. The four phases of platform evolution include the equilibrium, crisis, anoxic, and recovery stages. The equilibrium stage is characterized by progradational shelf geometries and coralrudist phototrophic faunal assemblages. Similar phototrophic fauna typify the crisis stage; however, incipient biocalcification crises of this phase led to retrogradational shelf morphologies, transgressive facies patterns, and increased clay mineral proportions. Anoxic stages of the Comanche Platform were coincident with back-ground deposition of organic-rich shale on drowned shelves and heterotrophic fauna dominated by oysters or coccolithophorids. Eustatic peaks of this stage were of moderate amplitude (similar to 30 m), yet relative sea-level rises were greatly enhanced by reduced sedimentation rates. In the recovery stage, heterotrophic carbonate factories re-established at the shoreline as progradational ramp systems and sediment accumulation rates slowly increased as dysoxia diminished. Full recovery to equilibrium conditions may or may not have followed. Geochemical and stratigraphic trends present in the four stages are consistent with increased volcanism along mid-ocean ridges and in large-igneous provinces as primary drivers of Cretaceous OAEs and the resulting transgressive-regressive composite sequences.
