The Impact Of Incarceration On The Risk Of Violent Recidivism

Whether incarceration heightens an individual’s likelihood of recidivating is at the center of prison policy discussions. Yet rigorous empirical studies on the nature of the incarceration—recidivism link are limited. As a whole, existing research suggests that the effect of imprisonment, relative to noncustodial sanctions, is either null or slightly criminogenic. These findings call into question the ability of prisons to exert a specific deterrent effect. They also suggest that prisons are failing to address the underlying causes of recidivism among inmate populations. An important consideration, however, is the extent to which the effects of imprisonment are heterogeneous. The current discussion further unpacks the effect of prison by considering whether and how imprisonment influences the risk of violent recidivism. This Article reviews the different theoretical perspectives invoked to explain the association between incarceration and future violence, as well as the existing research evidence. This Article concludes with implications for theory, research, and policy

Teaching water conservation to teachers of fourth-sixth grade students

This project inserviced teachers for grades fourth through sixth on water conservation activities that they could implement with their students. Project Wet (Water Education for Teachers) was used as the basis for the workshops. All selected activities correlated with the California State Content Standards

Quantifying imperfect detection in an invasive pest fish and the implications for conservation management

In managing non-native species, surveillance programmes aim to minimise the opportunity for invasions to develop from initial introductions through early detection. However, this is dependent on surveillance methods being able to detect species at low levels of abundance to avoid false-negative recordings through imperfect detection. We investigated through field experimentation the ability to detect Pseudorasbora parva, a highly invasive pest fish in Europe, in relation to their known density and sampling method. Secure pond mesocosms of area 100 m2 contained P. parva densities from 0.02 to 5.0 m"122; each density was in triplicate. These were searched using point sampling electric fishing and deployment of fish traps (non-baited and baited). No fish were captured at densities 0.5 m"122, whereas for electric fishing it only exceeded 0.95 at 5.0 m"122 using high searching effort. These data reveal that small pest fishes such as P. parva may be prone to imperfect detection when at low densities and this is consistent with a number of other invasive species. This indicates the importance of designing surveillance programmes using methods of known statistical power to optimise conservation resource expenditure and enhance management outcomes

The reactions of bromotrichloromethane and bromine with halogenated methanes

Over the past few years, the abstraction and addition reactions of trichloromethyl radicals, produced by the photolysis of bromotrichloromethane have been studied in this laboratory. The addition reactions of the trichloromethyl radical have thrown considerable light onto the factors influencing the direction of addition to substituted olefins. The hydrofen abstraction reactions from substituted alkanes have indicated that the trichloromethyl radical is comparable in selectivity to the bromine atom. The purpose of this work was to obtain absolute Arrhenius parameters for the abstraction of hydrogen from a representative selection of polychlorofluoromethanes. The results obtained are compared with the results obtained for similar reactions with methyl tadicals and trifluoromethyl radicals. In order to reduce the unknown rate constants in the computer analysis of the proposed reaction mechanism, the brominations of all the halomethanes, for which literature data did not exist, were carried out. The thesis is divided into two parts: - Part I deals with the reaction of trichloromethyl radicals with difluoromethane (section I); chlorofluoromethane (section II), dichloromethane (section III) and dichlorofluoromethane (section IV) and Part II deals with the competitive brominations of chlorofluoromethane, dichloromethane and dichlorofluoromethane

Neural tube closure: cellular, molecular and biomechanical mechanisms.

Neural tube closure has been studied for many decades, across a range of vertebrates, as a paradigm of embryonic morphogenesis. Neurulation is of particular interest in view of the severe congenital malformations - 'neural tube defects' - that result when closure fails. The process of neural tube closure is complex and involves cellular events such as convergent extension, apical constriction and interkinetic nuclear migration, as well as precise molecular control via the non-canonical Wnt/planar cell polarity pathway, Shh/BMP signalling, and the transcription factors Grhl2/3, Pax3, Cdx2 and Zic2. More recently, biomechanical inputs into neural tube morphogenesis have also been identified. Here, we review these cellular, molecular and biomechanical mechanisms involved in neural tube closure, based on studies of various vertebrate species, focusing on the most recent advances in the field

Batman Meets Gagne: Analyzing Commercial Video Game Instruction through the Lens of Instructional Design

This paper will examine how Gagne’s Nine Events of Instruction (1992) may appear, perhaps inadvertently, within commercial games that guide the user from novice to expert player. By employing a qualitative artifact analysis methodology, we examine a popular action adventure video game to determine if game designers encourage players to build game expertise by employing similar events to Gagne’s instructional design model. We demonstrate that our artifact of analysis does consistently employ Gagne’s events, though often in a manner unique to a digitally mediated space. We conclude that an experiential game setting has the potential to be a platform for instructional delivery

European Non-native Species in Aquaculture Risk Analysis Scheme - a summary of assessment protocols and decision support tools for use of alien species in aquaculture

The European Non-native Species in Aquaculture Risk Analysis Scheme (ENSARS) was developed in response to European 'Council Regulation No. 708/2007 of 11 June 2007 concerning use of alien and locally absent species in aquaculture' to provide protocols for identifying and evaluating the potential risks of using non-native species in aquaculture. ENSARS is modular in structure and adapted from non-native species risk assessment schemes developed by the European and Mediterranean Plant Protection Organisation and for the UK. Seven of the eight ENSARS modules contain protocols for evaluating the risks of escape, introduction to and establishment in open waters, of any non-native aquatic organism being used (or associated with those used) in aquaculture, that is, transport pathways, rearing facilities, infectious agents, and the potential organism, ecosystem and socio-economic impacts. A concluding module is designed to summarise the risks and consider management options. During the assessments, each question requires the assessor to provide a response and confidence ranking for that response based on expert opinion. Each module can also be used individually, and each requires a specific form of expertise. Therefore, a multidisciplinary assessment team is recommended for its completion
