    The Risk for Sexual Violence Protocol is a structured professional judgement (SPJ) tool that aids risk assessment of sexual violence. It is widely used internationally. The aim of this study was to explore the clinical practice of SPJ risk assessment and risk management through qualitative analysis of the accounts of users of these assessments. Questionnaires and semi-structured interviews were conducted with a sample of 31 criminal justice professionals in southeast Scotland. The participants' accounts were explored using the framework method. Five themes emerged from this analysis: informing risk management; confirming what was known and giving weight; understanding personality; treatment; and the usefulness and limitations of risk assessment. The participants reported that the assessments were influential with respect to risk management. The study revealed some important implications for service development. The authors suggest possible future use of the framework method in research investigating the risk assessment of sexual violence

    Prospects for the Search for a Standard Model Higgs Boson in ATLAS using Vector Boson Fusion

    Full text link
    The potential for the discovery of a Standard Model Higgs boson in the mass range m_H < 2 m_Z in the vector boson fusion mode has been studied for the ATLAS experiment at the LHC. The characteristic signatures of additional jets in the forward regions of the detector and of low jet activity in the central region allow for an efficient background rejection. Analyses for the H -> WW and H -> tau tau decay modes have been performed using a realistic simulation of the expected detector performance. The results obtained demonstrate the large discovery potential in the H -> WW decay channel and the sensitivity to Higgs boson decays into tau-pairs in the low-mass region around 120 GeV.Comment: 20 pages, 13 ps figures, uses EPJ style fil

    Late Holocene palynology and palaeovegetation of tephra-bearing mires at Papamoa and Waihi Beach, western Bay of Plenty, North Island, New Zealand.

    The vegetation history of two mires associated with Holocene dunes near the western Bay of Plenty coast, North Island, New Zealand, is deduced from pollen analysis of two cores. Correlation of airfall tephra layers in the peats, and radiocarbon dates, indicate that the mires at Papamoa and Waihi Beach are c. 4600 and c. 2900 conventional radiocarbon years old, respectively. Tephras used to constrain the chronology of the pollen record include Rotomahana (1886 AD), Kaharoa (700 yr B.P.), Taupo (Unit Y; 1850 yr B.P.), Whakaipo (Unit V; 2700 yr B.P.), Stent (Unit Q; 4000 yr B.P.), Hinemaiaia (Unit K; 4600 yr B.P.), and reworked Whakatane (c. 4800 yr B.P.) at Papamoa, and Kaharoa and Taupo at Waihi Beach. Peat accumulation rates at Papamoa from 4600 - 1850 yr B.P. range from 0.94 to 2.64 mm/yr (mean 1.37 mm/yr). At Waihi Beach, from 2900 yr B.P. - present day, they range from 0.11 to 0.21 mm/yr (mean 0.20 mm/yr). Peat accumulation at both sites was slowest from 1850 to 700 yr B.P., suggesting a drier overall climate during this interval. At both sites, the earliest organic sediments, which are underlain by marine or estuarine sands, yield pollen spectra indicating salt marsh or estuarine environments. Coastal vegetation communities declined at both sites, as sea level gradually fell or the coast prograded, and were eventually superseded by a low moor bog at Papamoa, and a mesotrophic swamp forest at Waihi Beach. These differences, and the marked variation in peat accumulation rates, probably reflect local hydrology and are unlikely to have been climatically controlled. The main regional vegetation during this period was mixed northern conifer-angiosperm forest. Kauri (Agathis australis) formed a minor component of these forests, but populations of this tree have apparently not expanded during the late Holocene at these sites, which are near its present southern limit. Occasional shortlived forest disturbances are detectable in these records, in particular immediately following the deposition of Taupo Tephra. However, evidence for forest clearance during the human era is blurred by the downward dislocation of modern adventi ve pollen at these sites, preventing the clear differentiation of the Polynesian and European eras

    Gateway to offending behaviour: permission-giving thoughts of online users of child sexual exploitation material.

    Get PDF
    The endorsement of permission-giving thoughts, or so-called cognitive distortions, has been discussed as a contributing factor in sexually abusive behaviour. The current study set out to explore the thinking patterns of offenders who have used/downloaded child sexual exploitation material (CSEM), based on a survey of professionals. A thematic analysis elicited four overarching themes, namely the Perceived Nature of Children (perception of children portrayed in CSEM, as well as children in general), Non-sexual Engagement with CSEM (motivating factors that are not inherently sexual in nature), Denial of Harm (perception of the level of harm caused by CSEM), and Expression of a General Sexual Preference (general interest in deviant sexual behaviour). These themes aid to explore the differences and similarities between contact and non-contact offenders and to improve the understanding of the role of permission-giving thoughts in this offending. Results are discussed in terms of their theoretical significance and future implications
