Inter-agency adult support and protection practice:a realistic evaluation with police, health and social care professionals

Purpose: Collaborative inter-agency working is of paramount importance for the public protection agenda worldwide. The purpose of this paper is to disseminate the findings from a research study on the inter-agency working within adult support and protection (ASP) roles in the police, health and social care.Design/methodology/approach: This realistic evaluation study with two inter-related phases was funded by the Scottish Institute for Policing Research. This paper reports on Phase 1 which identified existing gaps in the implementation of effective inter-agency practice by reviewing the “state of play” in inter-agency collaboration between the police and health and social care professionals. In total, 13 focus groups comprising representatives from Police Scotland (n¼52), Social Care (n¼31) and Health (n¼18), engaged in single profession and mixed profession groups addressing issues including referral and information exchange.Findings: On analysing context-mechanism-outcome (CMO), gaps in joint working were identified and attributed to the professionals’ own understanding of inter-agency working and the expectations of partner agencies. It recommended the need for further research and inter-agency training on public protection. Research limitations/implications – This unique Scottish study successfully identified the inter-agency practices of health, social services and police. By means of a modified realistic evaluation approach, it provides an in-depth understanding of the challenges that professionals face on a day-to-day basis when safeguarding adults and informed strategic recommendations to overcome the barriers to good practices in organisational working. The methods used to determine CMO could benefit other researchers to develop studies exploring the complexities of multi-causal effects of cross-boundary working. The use of the same case study in each focus group helped to neutralise bias. However, the voluntary nature of participation could have resulted in biased perceptions. The limited numbers of health professionals may have resulted in less representation of health sector views.Practical implications: Collaborative inter-agency working is of paramount importance for public protection worldwide. This paper reports on a Scottish study that focussed on the coordinated and integrated practices amongst the police, health and social services’ professionals who support and protect adult members of society at risk of harm.Social implications: Whilst the focus of this study has been on ASP, the conclusions and recommendations are transferable to public protection issues in many other contexts.Originality/value: Studies on the joint-working practices amongst police and health and social services’ professionals who support and protect adult members of society at risk of harm are uncommon. This  study investigated professionals’ perceptions of gaps and concerns pertaining to integrated working by means of a realistic evaluation approach. It recommended the need for further research and inter-agency training on public protection

Prion infectivity in the spleen of a <em>PRNP</em> heterozygous individual with subclinical variant Creutzfeldt-Jakob disease

Blood transfusion has been identified as a source of human-to-human transmission of variant Creutzfeldt–Jakob disease. Three cases of variant Creutzfeldt–Jakob disease have been identified following red cell transfusions from donors who subsequently developed variant Creutzfeldt–Jakob disease and an asymptomatic red cell transfusion recipient, who did not die of variant Creutzfeldt–Jakob disease, has been identified with prion protein deposition in the spleen and a lymph node, but not the brain. This individual was heterozygous (MV) at codon 129 of the prion protein gene (PRNP), whereas all previous definite and probable cases of variant Creutzfeldt–Jakob disease have been methionine homozygotes (MM). A critical question for public health is whether the prion protein deposition reported in peripheral tissues from this MV individual correlates with infectivity. Additionally it is important to establish whether the PRNP codon 129 genotype has influenced the transmission characteristics of the infectious agent. Brain and spleen from the MV blood recipient were inoculated into murine strains that have consistently demonstrated transmission of the variant Creutzfeldt–Jakob disease agent. Mice were assessed for clinical and pathological signs of disease and transmission data were compared with other transmission studies in variant Creutzfeldt–Jakob disease, including those on the spleen and brain of the donor to the index case. Transmission of variant Creutzfeldt–Jakob disease was observed from the MV blood recipient spleen, but not from the brain, whereas there was transmission from both spleen and brain tissues from the red blood cell donor. Longer incubation times were observed for the blood donor spleen inoculum compared with the blood donor brain inoculum, suggesting lower titres of infectivity in the spleen. The distribution of vacuolar pathology and abnormal prion protein in infected mice were similar following inoculation with both donor and recipient spleen homogenates, providing initial evidence of similar transmission properties after propagation in PRNP codon 129 MV and MM individuals. These studies demonstrate that spleen tissue from a PRNP MV genotype individual can propagate the variant Creutzfeldt–Jakob disease agent and that the infectious agent can be present in the spleen without CNS involvement

Biomechanics of predator–prey arms race in lion, zebra, cheetah and impala

The fastest and most manoeuvrable terrestrial animals are found in savannah habitats, where predators chase and capture running prey. Hunt outcome and success rate are critical to survival, so both predator and prey should evolve to be faster and/or more manoeuvrable. Here we compare locomotor characteristics in two pursuit predator–prey pairs, lion–zebra and cheetah–impala, in their natural savannah habitat in Botswana. We show that although cheetahs and impalas were universally more athletic than lions and zebras in terms of speed, acceleration and turning, within each predator–prey pair, the predators had 20% higher muscle fibre power than prey, 37% greater acceleration and 72% greater deceleration capacity than their prey. We simulated hunt dynamics with these data and showed that hunts at lower speeds enable prey to use their maximum manoeuvring capacity and favour prey survival, and that the predator needs to be more athletic than its prey to sustain a viable success rate

Irrigated rice practices changes in the Senegal River Valley according to climate and constraints evolutions. [P14]

More and more irrigated rice farms of the Senegal River Valley (SRV) no longer respect the sowing periods promoted in the 90s to reduce sterility risks due to extreme temperatures. This study aims at understanding that reality and assess ing whether new sowing periods must be defined. Combining focus - groups and surveys, climate analysis, field experiments and modeling work with RIDEV model, it addresses the evolution of cropping practices and their constraints, farmers ' climate perception, climate evolution and its consequences on rice development and sowing periods in the SRV. Data analysis shows rainfalls and temperature increases, and particularly a significant increase between the present decade and the 1950 - 1980 per iod which was considered for the establishment of the recommended sowing windows (+1°C to +2°C on monthly averages for Podor), with less extreme cold temperatures and more extreme hot ones. Farmers are very aware about recent climate evolution, with respec tively 94% and 72% of them saying that rainfall and temperature patterns have changed. More precisely they commented that “the cold period shifted by about one month, from “October/November – February/March” to “November – March/April”. Nevertheless the ma jority considers that the recommended sowing periods are still pertinent and explain that late sowings are due to delayed access to tractors, inputs and credits. Only few ones (5 %) intentionally sow late, considering there is no longer a danger in doing t hat. However, in 2011 farmers who sown later got very bad yield and farmers explain that “because the cold arrived earlier as it happened in the past”. Yet, while farmer's comments appear coherent with climate data, up to now we can't totally confirm them by crop modelling since we still have difficulties in the simulation of the sterility despite recent model improvements. Additional work is required to reach a conclusion . (Résumé d'auteur
