    This thesis examined decision making in the context of forced-choice situations, as characterised by high-risk consequences and time-limited conditions, within an experimental decision paradigm. By mapping onto basic decision-making stages relating to evaluation, deliberation and implementation of a choice, this research looks at how environmental conditions (emotion) and information (advice) affect cognitive processing in forced-choice or “do or don’t” scenarios. In order to identify these variations on a more fundamental level, a methodological framework was developed, which incorporates neurocognitive, behavioural and qualitative measures. Results identified the distinct sequence of cognitive processes as predicted from basic decision-making models. When individuals lacked any meaningful information to assist in solving the tasks, their responses varied based on the consequential conditions they faced, leading to an accelerated engagement with the decision and faster response, the riskier the outcome. On the other hand, when information was available during the task, differences in responses followed predictions about information processing and cognitive effort required for the different levels of clarity. Here, the consequential conditions did not affect performance, as individuals prioritised the information available. Further, when solving a task lacking any meaningful information on which to base their choice, individuals still engaged in redundant deliberation. Taken together, the research suggests that outcome uncertainty and task ambiguity have a demonstrable effect on the decision-making process. This research, incorporating neurocognitive measures, showed a robust framework to advance current understanding about the interplay of affecting factors and basic decision-making processes. Providing an additional reference, this approach contributes to a more in-depth picture of underlying processes

    Few studies have been done examining noise exposures associated with agricultural tasks. This study was conducted to address that research gap by calculating the noise exposures for tasks and equipment associated with grain production and assessing the variability in those exposures. An additional aim of this study was to identify tasks and equipment that could be targeted for intervention strategies as a means toward reducing the total noise exposures of farmers and farm workers. Through the use of personal noise dosimetry and direct observation, over 30,000 one-minute noise exposure measurements and corresponding task and equipment data were collected on 18 farms and compiled into a task-based noise exposure database. Mean noise exposures were calculated for 23 tasks and 18 pieces of equipment. The noise exposures for the tasks and equipment ranged from 78.6 to 99.9 dBA and from 80.8 to 96.2 dBA, respectively, with most of the noise exposures having a large standard deviation and maximum noise exposure level. Most of the variability in the task and equipment noise exposures was attributable to within-farm variations (e.g., work practices, distance from noise sources). Comparisons of the mean noise exposures for the agricultural tasks and equipment revealed that most were not statistically different. Grain production tasks and equipment with high mean noise exposures were identified. However the substantial variability in the noise exposures and the occurrence of intense noise measurements for nearly every task and piece of equipment indicate that targeting a few specific tasks or equipment for intervention strategies would reduce lifetime noise exposure but would not completely eliminate exposure to hazardous noise levels

    Observing Rapport-Based Interpersonal Techniques (ORBIT) To Generate Useful Information From Child Sexual Abuse Suspects

    In the United Kingdom alone, it is estimated that between 550,000 - 850,000 individuals pose varying degrees of sexual risk to children (with a central estimate of 700,000; National Crime Agency, 2021). Whilst the interview process is central to information gathering, empirical research focusing on child sexual abuse (CSA) suspect interviewing is limited. The present study analyses 45 hours of interviews with CSA suspects using the Observing Rapport-Based Interpersonal Techniques (ORBIT) framework. Originally used to code interviews with terrorist suspects (see Alison et al., 2013), this is the first application of ORBIT to another offender population. The ORBIT framework consists of three elements: (i) Motivational Interviewing skills (MI; Miller & Rollnick, 2009) include autonomy, acceptance, adaptation, empathy, and evocation; and (ii) the Interpersonal Behaviour Circle (IBC; Leary, 1955) measures interviewer and suspect interactions along two orthogonal dimensions (control-capitulate and confront-cooperate). Each IBC quadrant has adaptive (promoting conversation) and maladaptive (hampering communication) facets. The third element of ORBIT is an outcome measure of information that is of evidential significance or intelligence value – the ‘interview yield’. Multilevel structural equation modelling revealed interviewer adaptive/maladaptive behaviours had a direct impact on suspect adaptive/maladaptive behaviours respectively which, in turn, were associated with interview yield. Further, MI was associated with decreased suspect maladaptive (though not increased adaptive) behaviours. The study provides further support for the ORBIT research from Alison et al. (2013) in a new criminal population. It highlights that interviewers who adopt a rapport- based and interpersonally skilled approach will have information-gathering success with CSA suspects

    An Economic Evaluation of the Impact of Using Rapport-Based Interviewing Approaches With Child Sexual Abuse Suspects

    Two studies examined whether rapport-based interviewing with child sexual abuse (CSA) suspects provides greater interview yield that could result in overall cost-savings to the investigation. First, multi-level modelling was applied to 35 naturalistic CSA suspect interviews to establish whether rapport-based interviewing techniques increase “yield” – defined as information of investigative value. The Observing Rapport Based Interviewing Technique (ORBIT coding manual was used to code interviews; it includes an assessment of both interpersonal adaptive and maladaptive rapport-based interviewer engagement as well as motivational interviewing (MI) strategies. The impact of these two strands (interpersonal and MI) on extracting information of investigative value (including strengthening a case for court and safeguarding) were examined. Adaptive interpersonal strategies increased case strengthening and safeguarding yield, with motivational interviewing having the largest impact on safeguarding yield. Both strategies increase the likelihood of gaining additional types of economic yield. Maladaptive interviewer strategies reduced case strengthening and different types of economic yield. In study two, literature-based economic estimates were applied to establish the potential cost benefits from following national ORBIT rapport training. Further training in adaptive and motivational interviewing could contribute cost savings between £19 and £78 million (annual unit costs) increasing to £238–£972 million (lifetime costs) for online CSA across England and Wales; and £157–£639 million (annual unit costs) increasing to £2–£8 billion (lifetime costs) for all CSA. Failure to commit training resource to this, or an alternative strategy, could mean the cost burden attributable to maladaptive interviewing (between £1 and £6 million for online CSA and £12 and £48 million for all CSA) is not successfully averted

    Between a rock and a hard place of geopolitically sensitive threats - critical incidents and decision inertia

    While the SAFE-T model of decision making emphasizes naturalistic decision making, its potential for cross-comparative analysis of incidents with global implications remains underutilized, which the current paper aims to address. To this end, it draws upon open-source reports from unclassified American, British and Russian intelligence reports to explore the management of three types of 10 high-profile geopolitically sensitive threats from across the globe (verifying potential terrorist identity, hostage rescue and national/international security). Defining features of such incidents include decision makers’ ability to prospectively model competing scenarios in which they must select between options and where every outcome looks aversive and high risk (‘damned if you do or damned if you don’t decisions’). A frequent consequence of such calculations is ‘decision inertia’ (a failure to execute an important, irrevocable decision resulting in non-optimal consequences), or ‘implementation failure’ (a failure to make a choice). Combining the benefit of the theoretical framework and hindsight knowledge of the analyzed incidents, the paper facilitates theoretical understanding of decision inertia and failures to act. Encouraging the consideration of multiple scenario endings contingent on a wide spectrum of factors and unique cultural-historical context, it also helps identify past decision errors in order to inform assessment and management of similar geopolitical threats in the future

    COVID-19 risk-mitigation in reopening mass events: population-based observational study for the UK Events Research Programme in Liverpool City Region

    OBJECTIVES: To understand severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission risks, perceived risks and the feasibility of risk mitigations from experimental mass cultural events before coronavirus disease 2019 (COVID-19) restrictions were lifted. DESIGN: Prospective, population-wide observational study. SETTING: Four events (two nightclubs, an outdoor music festival and a business conference) open to Liverpool City Region UK residents, requiring a negative lateral flow test (LFT) within the 36 h before the event, but not requiring social distancing or face-coverings. PARTICIPANTS: A total of 12,256 individuals attending one or more events between 28 April and 2 May 2021. MAIN OUTCOME MEASURES: SARS-CoV-2 infections detected using audience self-swabbed (5-7 days post-event) polymerase chain reaction (PCR) tests, with viral genomic analysis of cases, plus linked National Health Service COVID-19 testing data. Audience experiences were gathered via questionnaires, focus groups and social media. Indoor CO2 concentrations were monitored. RESULTS: A total of 12 PCR-positive cases (likely 4 index, 8 primary or secondary), 10 from the nightclubs. Two further cases had positive LFTs but no PCR. A total of 11,896 (97.1%) participants with scanned tickets were matched to a negative pre-event LFT: 4972 (40.6%) returned a PCR within a week. CO2 concentrations showed areas for improving ventilation at the nightclubs. Population infection rates were low, yet with a concurrent outbreak of >50 linked cases around a local swimming pool without equivalent risk mitigations. Audience anxiety was low and enjoyment high. CONCLUSIONS: We observed minor SARS-CoV-2 transmission and low perceived risks around events when prevalence was low and risk mitigations prominent. Partnership between audiences, event organisers and public health services, supported by information systems with real-time linked data, can improve health security for mass cultural events

    The genomes of two key bumblebee species with primitive eusocial organization

    Get PDF
    Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome sequences of Bombus terrestris and Bombus impatiens, two ecologically dominant bumblebees and widely utilized study species. Comparing these new genomes to those of the highly eusocial honeybee Apis mellifera and other Hymenoptera, we identify deeply conserved similarities, as well as novelties key to the biology of these organisms. Some honeybee genome features thought to underpin advanced eusociality are also present in bumblebees, indicating an earlier evolution in the bee lineage. Xenobiotic detoxification and immune genes are similarly depauperate in bumblebees and honeybees, and multiple categories of genes linked to social organization, including development and behavior, show high conservation. Key differences identified include a bias in bumblebee chemoreception towards gustation from olfaction, and striking differences in microRNAs, potentially responsible for gene regulation underlying social and other traits. Conclusions: These two bumblebee genomes provide a foundation for post-genomic research on these key pollinators and insect societies. Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation
