    The reactions pi /sup -/ + p yields p + p + n and pi /sup -/ + p yields p + d were investigated. The calculations are based on thirdorder perturbation theory with pseudoscalar coupling between nucleons and pions and with a phenomenological treatment of the nucleon-nucleon interaction in the final state. The final-state interactions of the antinucleon are neglected. Cross sections are given in graphical form for the reactions and for trsnsitions between eigenstates of isotopic spin. The final-state nucleon-nucleon interaction is shown to have a lnrge effect on the cross sections. The cross section for the reaction pi /sup -/ + p yields p + d is found to be relatively large. At an energy of 10 Mev abcve threshold in the center-of-momentum system the ratio of this cross section to that for pi /sup -/ + p yields p + p + n is about 5: 1. At an energy of 40 Mev above threshold this ratio hns decreased to 1: I. The total cross section for the reaction leading to the unbound final state is calculated by assuming a modified Fermi statistical model. At an energy 100 Mev above threshold, this cross section is approximately 0.1 mb. A theoretical expression for the transition amplitude is developed. (auth

    Environmental harm and environmental victims: scoping out a ‘green victimology'

    In this paper I intend to discuss the adaptability of victimological study to the question of ‘environmental victimisation’. The impact on those affected by environment crime, or other environmentally damaging activities, is one that has received scarce attention in the mainstream victimological literature (see Williams, 1996). The role or position of such victims in criminal justice and/or other processes has likewise rarely been topic of academic debate. I have recently expanded upon various aspects of this subject and surrounding issues at greater length (Hall, 2013) but for the purposes of this article I wish to expand specifically on what a so-called ‘green victimology’ might look like, together with some of the particular questions and challenges it will face

    An ideology critique of global citizenship education

    Get PDF
    In the last two decades, global citizenship education (GCE) has become a catchphrase used by international and national educational agencies, as well as researchers, to delineate the increasing internationalisation of education, framed as an answer to the growing globalisation and the high values of citizenship. These developments, however, have created issues, due to the presence of two conflicting discourses. While the discourse of critical democracy highlights the importance of ethical values, social responsibility and active citizenry, a neoliberal discourse privileges instead a market-rationale, focused on self-investment and enhanced profits. These two discourses are not separated; they rather appear side by side, causing a confusing effect. This article aims to analyse GCE as an ideology, unveiling not only its hidden (discursive) content but also the role played by non-discursive elements in guaranteeing the coexistence of antagonistic discourses. It will be argued that not only the critical democratic discourse does not offer any resistance or threat to the neoliberal structuring of higher education, but also this discourse can function as an apologetic narrative that exculpates all of us who still want to work in universities, notwithstanding our dissatisfaction with their current commodification
