From Counter-terrorism to Criminal Justice: Transformation or Business as Usual?

The article explores the extent to which criminal justice in Northern Ireland has been reconstructed over the past fifteen years. The focus is on the framework provided in the Good Friday Agreement (1998) and the range of transition processes that followed. Post-Agreement Inquiries are reviewed and the findings demonstrate the institutional rigidities facing the transformation of criminal justice. While the ideologies and practices of counter-terrorism no longer dominate the business of criminal justice, the extent of change in terms of social representativeness, scale and expenditure is variable, with the prison service proving the least changed.

Microarray-based classifiers and prognosis models identify subgroups with distinct clinical outcomes and high risk of AML transformation of myelodysplastic syndrome

The diagnosis of myelodysplastic syndrome (MDS) currently relies primarily on the morphologic assessment of the patient's bone marrow and peripheral blood cells. Moreover, prognostic scoring systems rely on observer-dependent assessments of blast percentage and dysplasia. Gene expression profiling could enhance current diagnostic and prognostic systems by providing a set of standardized, objective gene signatures. Within the Microarray Innovations in LEukemia study, a diagnostic classification model was investigated to distinguish the distinct subclasses of pediatric and adult leukemia, as well as MDS. Overall, the accuracy of the diagnostic classification model for subtyping leukemia was approximately 93%, but this was not reflected for the MDS samples giving only approximately 50% accuracy. Discordant samples of MDS were classified either into acute myeloid leukemia (AML) or

Two routes to leukemic transformation after a JAK2 mutation-positive myeloproliferative neoplasm

Acute myeloid leukemia (AML) may follow a JAK2-positive myeloproliferative neoplasm (MPN), although the mechanisms of disease evolution, often involving loss of mutant JAK2, remain obscure. We studied 16 patients with JAK2-mutant (7 of 16) or JAK2 wild-type (9 of 16) AML after a JAK2-mutant MPN. Primary myelofibrosis or myelofibrotic transformation preceded all 7 JAK2-mutant but only 1 of 9 JAK2 wild-type AMLs (P = .001), implying that JAK2-mutant AML is preceded by mutation(s) that give rise to a "myelofibrosis" phenotype. Loss of the JAK2 mutation by mitotic recombination, gene conversion, or deletion was excluded in all wild-type AMLs. A search for additional mutations identified alterations of RUNX1, WT1, TP53, CBL, NRAS, and TET2, without significant differences between JAK2-mutant and wild-type leukemias. In 4 patients, mutations in TP53, CBL, or TET2 were present in JAK2 wild-type leukemic blasts but absent from the JAK2-mutant MPN. By contrast in a chronic-phase patient, clones harboring mutations in JAK2 or MPL represented the progeny of a shared TET2-mutant ancestral clone. These results indicate that different pathogenetic mechanisms underlie transformation to JAK2 wild-type and JAK2-mutant AML, show that TET2 mutations may be present in a clone distinct from that harboring a JAK2 mutation, and emphasize the clonal heterogeneity of the MPNs.

Conflict, Transformation, and Former Loyalist Paramilitary Prisoners in Northern Ireland

Following the 1998 Belfast Agreement in Northern Ireland, levels of paramilitary violence have declined substantially. Among loyalists, the Ulster Volunteer Force (UVF) and associated Red Hand Commando (RHC) have formally renounced violence, and dissolved their 'military structures', and perhaps the most reticent of all of the major paramilitary groupings, the Ulster Defence Association (UDA), has taken on board the central tenets of conflict transformation, and 'stood down' all of its 'active service units' in the Ulster Freedom Fighters (UFF). Thus, paramilitary violence now is mainly confined to the activities of 'dissident' republican groups, notably the Real and Continuity IRAs, although low-level sectarian violence remains a problem. Such dramatic societal and political change has resulted in a focus on the roles of formal party political leadership as agents of social change. This gaze, however, tends to obscure other important events such as the efforts, structures and approaches taken at the grassroots level to uphold and sustain conflict transformation and to maintain a reduction in violence. This article provides analysis of the role played by former loyalist paramilitary combatants in conflict transformation, and draws on material obtained through significant access to those former paramilitaries engaged in processes of societal shifts. In both personal and structural terms there is evidence of former combatants working to diminish the political tensions that remain as a result of the long-term inter-communal hostility developed across decades of violence and conflict.

Re-imagining DDR Ex-combatants, leadership and moral agency in conflict transformation

Drawing upon criminological studies in the field of prisoner rehabilitation, this essay explores the relevance of the Demobilisation, Disarmament and Reintegration (DDR) framework to the process of conflict transformation in Northern Ireland. In a similar fashion to the critique of 'passivity' offered by, for example, the 'strengths based' or 'good lives' approach to prisoner resettlement and reintegration more generally, the authors contend that the Northern Ireland peace process offers conspicuous examples of former prisoners and combatants as agents and indeed leaders in the process of conflict transformation. They draw out three broad styles of leadership which have emerged amongst ex-combatants over the course of the Northern Ireland transition from conflict-political, military and communal. They suggest that cumulatively such leadership speaks to the potential of ex-prisoners and ex-combatants as moral agents in conflict transformation around which peacemaking can be constructed rather than as obstacles which must be 'managed' out of existence.

Resistance, transition and exclusion: Politically motivated ex-prisoners and conflict transformation in Northern Ireland

The landscape of political imprisonment in Northern Ireland was changed due to the general release and reintegration of politically motivated prisoners as part of the Belfast Agreement. This article reflects upon the post-prison experiences of former prisoners and their families, and in particular how the move from a resistant to a transitional framework has facilitated a greater openness and willingness amongs ex-prisoners to acknowledge the personal and familial problems related to incarceration. We also explore the ways in which ex-prisoners have attempted to deal with the continued social, political and civic exclusion which arises as a result of their conflict-related 'criminal' convictions. In the final section of the article, the authors further develop the move from a resistant to a transitional characterization of incarceration and its consequences.

Prokaryotes on the tentacles of deep-sea holothurians: A novel form of dietary supplementation

Bathyal and abyssal epibenthic holothurians have a layer of bacteria lying over the tentacular epidermis and below the cuticle. Thus the tentacles of deep-sea holothurians may provide ideal conditions for subcuticular bacteria. These bacteria appear to be regulated by phagocytosis, which, together with pinocytosis would facilitate transfer of bacterial metabolites to the holothurian. Their abundance suggests a previously unknown pathway for energy transformation and assimilation of particular significance in an environment where food is limiting.

Transformation of vaterite into calcite in the absence and the presence of copper(II) species. Thermal analysis, IR and EPR study

The transformation of vaterite into calcite may be performed by heating in the presence and the absence of oxygen. Vaterite remains thermally stable until a calcination temperature of 450°C. It transforms progressively to calcite up to 500°C giving two exothermic peaks: 1) at 481°C due to the transformation of vaterite surface which is in contact with a small amount of calcite phase already formed with the time on the solid surface from the humidity atmosphere; 2) at 491°C due to the transformation of pure vaterite bulk. The calcite phase remains stable until 700°C. Above this temperature the formation of CaO is observed.

Variation in stable carbon isotope fractionation during aerobic degradation of phenol and benzoate by contaminant degrading bacteria

Variation in the natural abundance stable carbon isotope composition of respired CO2 and biomass has been measured for two types of aerobic bacteria found in contaminated land sites. Pseudomonas putida strain NCIMB 10015 was cultured on phenol and benzoate and Rhodococcus sp. I-1 was cultured on phenol. Results indicate that aerobic isotope fractionations of differing magnitudes occur during aerobic biodegradation of these substrates with an isotopic depletion in the CO2 (Delta(13)C(phenol-CO2)) as much as 3.7 parts per thousand and 5.6 parts per thousand for Pseudomonas putida and Rhodococcus sp. I-1 respectively. This observation has significant implications for the use of a stable isotope mass balance approach in monitoring degradation processes that rely on indigenous bacterial populations. The effects of the metabolic pathway utilised in degradation and inter-species variation on the magnitude of isotope fractionation are discussed. Possible explanations for the observed isotope fractionation include differences in the metabolic pathways utilised by the organisms and differences in specific growth rates and physiology.

Contrasting effects of a nonionic surfactant on the biotransformation of polycyclic aromatic hydrocarbons to cis-dihydrodiols by soil bacteria

The biotransformation of the polycyclic aromatic hydrocarbons (PAHs) naphthalene and phenanthrene was investigated by using two dioxygenase-expressing bacteria, Pseudomonas sp. strain 9816/11 and Sphingomonas yanoikuyae B8/36, under conditions which facilitate mass-transfer limited substrate oxidation. Both of these strains are mutants that accumulate cis-dihydrodiol metabolites under the reaction conditions used. The effects of the nonpolar solvent 2,2,4,4,6,8,8-heptamethylnonane (HMN) and the nonionic surfactant Triton X-100 on the rate of accumulation of these metabolites were determined. HMN increased the rate of accumulation of metabolites for both microorganisms, with both substrates. The enhancement effect was most noticeable with phenanthrene, which has a lower aqueous solubility than naphthalene. Triton X-100 increased the rate of oxidation of the PAHs with strain 9816/11 with the effect being most noticeable when phenanthrene was used as a substrate. However, the surfactant inhibited the biotransformation of both naphthalene and phenanthrene with strain B8/36 under the same conditions. The observation that a nonionic surfactant could have such contrasting effects on PAH oxidation by different bacteria, which are known to be important for the degradation of these compounds in the environment, may explain why previous research on the application of the surfactants to PAH bioremediation has yielded inconclusive results. The surfactant inhibited growth of the wild-type strain S. yanoikuyae B1 on aromatic compounds but did not inhibit B8/36 dioxygenase enzyme activity in vitro.

The transformation of cyclohexane on Zn/H-ZSM-5 zeolites

Samples of Zn/H-ZSM-5 zeolite were prepared by impregnation of the parent zeolite with Zn(NO3)(2). The state of zinc in the samples was analyzed by XPS measurements, (ald the degree of reduction for the zinc oxide on the ZSM-5 zeolite surface in hydrogen atmosphere was determined, as well as the influence of this reducing treatment upon the activity and selectivity for aromatics of zeolites in aromatization of cyclohexane. It resulted that the degree of reduction depends on the concentration of zinc in the zeolite and is influenced by the presence of alumina binder. The results of the activity and selectivity to aromatics were correlated with the reduction of zinc oxide.
