Automated Multimodal Data Capture for Photorealistic Construction Progress Monitoring in Virtual Reality

Construction monitoring is vital for the timely delivery of projects. However manual data collection and fusion methods are arduous. We propose a framework for autonomous multimodal data collection and VR visualisation. Based on “work-in-progress” results we demonstrate its capabilities in-the-lab and validate its functionality on a real site. We explore how such a framework could complement construction-centric deep learning and 4D as-built datasets to aid human decision-making using V

Evaluating Immersive Teleoperation Interfaces: Coordinating Robot Radiation Monitoring Tasks in Nuclear Facilities

We present a virtual reality (VR) teleoperation interface for a ground-based robot, featuring dense 3D environment reconstruction and a low latency video stream, with which operators can immersively explore remote environments. At the UK Atomic Energy Authority's (UKAEA) Remote Applications in Challenging Environments (RACE) facility, we applied the interface in a user study where trained robotics operators completed simulated nuclear monitoring and decommissioning style tasks to compare VR and traditional teleoperation interface designs. We found that operators in the VR condition took longer to complete the experiment, had reduced collisions, and rated the generated 3D map with higher importance when compared to non-VR operators. Additional physiological data suggested that VR operators had a lower objective cognitive workload during the experiment but also experienced increased physical demand. Overall the presented results show that VR interfaces may benefit work patterns in teleoperation tasks within the nuclear industry, but further work is needed to investigate how such interfaces can be integrated into real world decommissioning workflows

The nature of trauma memories in acute stress disorder in children and adolescents

Background: There is increasing theoretical, clinical and research evidence for the role of trauma memory in the aetiology of acute pathological stress responses in adults. However, research into the phenomenology of trauma memories in young people is currently scarce. Methods: This study compared the nature of trauma narratives to narratives of unpleasant non-traumatic events in young people (aged 8-17) who sought emergency medical attention following an assault or road traffic accident. Data were collected within 2-4 weeks of the index event. Symptom severity was assessed by child self-report and face-to-face diagnostic interviews. Comparisons of narrative indices were made between those children with acute stress disorder (ASD) and those without ASD. Results: Among participants (n = 50), those with ASD (38%) had significantly elevated levels of disorganisation in their trauma narrative, compared both to trauma-exposed controls and to their unpleasant comparative narrative. This effect was not accounted for by age. Regardless of ASD diagnostic status, trauma narratives had significantly higher sensory content and significantly lower positive emotion content compared to the unpleasant comparative narrative. These effects were not significant when age was included as a covariate. Acute symptom severity was significantly predicted by the level of disorganisation in the trauma narrative and the child's cognitive appraisals of the event. Conclusions: These data provide the first empirical evidence that disorganisation is not only directly linked to symptom severity, but also specific to the trauma memory. In addition, it provides support for the adaptation of adult cognitive models to acute pathological stress reactions in children and adolescents

Intrusive memories and depression following recent non-traumatic negative life events in adolescents

Background: Research in adults suggests that intrusive memories are not just found in individuals with post-traumatic stress disorder (PTSD), yet there is little evidence concerning the phenomenology of intrusive memories in children and adolescents. The present study investigated the frequency of intrusive memories following a recent negative event in an adolescent school sample, and considered the application of cognitive theory to understanding the maintenance of intrusive memories of recent negative events, and their role in maintaining depression. Methods: High school students (aged 11-18 years; n = 231) completed questionnaires concerning affect experienced during a recent negative event, the frequency of subsequent intrusive memories, memory quality, thought suppression, post-traumatic stress and depressive symptoms. Results: Most participants had experienced at least one intrusive memory in the previous week, at similar rates for traumatic events and life events. In non-trauma exposed youth, peri-event affect and memory quality accounted for unique variance in a regression model of intrusive memory frequency, while peri-event affect, memory quality, and intrusive memory frequency accounted for unique variance in a regression model of depression. Limitations: The study needs replication in younger children. Interview methods may be required to ensure that intrusive memories are being assessed and not intrusive thoughts or ruminations. Conclusions: Intrusive memories are common reaction to negative events in adolescents, and may be involved in maintaining subsequent depressed mood. The nature of event memories may have a role in the maintenance of such psychopathology, and may be a target for psychological interventions in this age group

Neoliberalism and the unfolding patterns of young people’s political engagement and political participation in contemporary Britain

Recent trends suggest that young people in Britain are increasingly rejecting electoral politics. However, evidence suggests that British youth are not apolitical, but are becoming ever more sceptical of the ability of electoral politics to make a meaningful contribution to their lives. Why young people are adopting new political behaviour and values, however, is still a point of contention. Some authors have suggested that neoliberalism has influenced these new patterns of political engagement. This article will advance this critique of neoliberalism, giving attention to three different facets of neoliberalism and demonstrate how they combine to reduce young people’s expectations of political participation and their perceptions of the legitimacy of political actors. We combine ideational and material critiques to demonstrate how young people’s political engagement has been restricted by neoliberalism. Neoliberalism has influenced youth political participation through its critiques of collective democracy, by the subsequent transformations in political practice that it has contributed to, and through the economic marginalisation that has resulted from its shaping of governments’ monetary policy. This approach will be conceptually predicated on a definition of neoliberalism which acknowledges both its focus on reducing interventions in the economy, and also its productive capacity to modify society to construct market relations and galvanise competition amongst agents. From this definition, we develop the argument that neoliberal critiques of democracy, the subsequent changes in political practices which respond to these criticisms and the transformation in socioeconomic conditions caused by neoliberalism have coalesced to negatively influence young people’s electoral participation

'An Apotheosis of Well-Being': Durkheim on austerity and double-dip recessions

This article is an attempt to contribute a view on the economic crisis from classical sociology, a voice often missing from the sociological response to the crisis. The work of Émile Durkheim provides a unique perspective here centred on morality and inequality produced in a historical context akin to our neoliberal times. It is argued there are four key points to take from Durkheim’s work. Firstly, that the initial credit crunch can be more fully understood with reference to the economic anomie which Durkheim sees as ‘chronic’ in a time of marketization. Secondly, that this creates an antagonistic relationship between a supposedly self-dependent rich and lazy poor. Thirdly, this conception of self-dependency and individual initiative makes any attempt to regulate the economy akin to sacrilege. Finally, the state is unwilling to intervene due to the emergence of ‘pseudo-democracies’. Therefore, Durkheim’s theory accounts for the initial crisis, austerity and double-dip recessions in a sociological framework. The article concludes by returning to the centrality of morality to the crisis for Durkheim and highlighting the omission of this in contemporary debates

The role of fishing material culture in communities’ sense of place as an added-value in management of coastal areas

Fishing communities in many places around the world are facing significant challenges due to new policies and environmental developments. While it is imperative to ensure sustainability of natural resources, many policies may overlook the contribution of fisheries to the sociocultural well-being of coastal communities. Authors address the problem of valuing the sociocultural benefits of fishing by exploring the role of fishing landscapes and traditional working waterfronts in maintaining sense of place in fishing communities. The paper explores how sense of place contributes to understanding the relationship between fishing and cultural-ecosystem services, drawing on case studies from four U.S. fishing communities in Brunswick County, North Carolina. Through semi-structured and in-depth interviews with fishing communities members, resident photography and sites visits, this paper outlines how fishing contributes to sense of place in terms of placeattachment and cultural-social memory. By understanding the relationship between fishers’ sense of place, and the physical environment in fishing communities in Brunswick County, the authors identify the complexity and interrelated elements that shape the relationship between fishermen and their cultural landscape. The paper suggests that realizing the value of fishing cultural landscape can encourage policies that promote preservation of fishing cultural heritage for the sociocultural benefit of communitie

The prevalence of intrusive memories in adult depression: A meta-analysis

Background Intrusive memories have typically been associated with post-traumatic stress disorder (PTSD) but some studies have suggested they can also occur in depression-alone. Objective This meta-analysis aimed to estimate the prevalence of intrusive memories in adult depression and to explore methodological and other factors that may moderate this prevalence. Method The databases PsycINFO, PsycARTICLES, MedLine, PubMed, CINAHL and Embase were searched for relevant articles, published up to and including July 2016. Studies measuring point prevalence of intrusive memories in adults aged 18 years or above with depression were included and assessed for quality. Meta-analysis was completed under a random effects model. Results Seven studies measuring point prevalence of intrusive memories in adult depression were included. The overall pooled prevalence estimate calculated was 76.0% (95% CI 59.4 – 89.4%), reducing to 66.0% (95% CI 51.0 – 79.5%) when restricted to intrusive memories experienced within the week prior to assessment. Heterogeneity was high. Between-groups analyses indicated that adults with depression are as likely to experience intrusive memories as adults with PTSD, and more likely to experience intrusive memories than healthy controls (risk ratio of 2.94, 95% CI 1.53 – 5.67). Limitations The strength of conclusions is limited by the small number of studies included. Consideration of the relationship between depression, intrusive memories and trauma exposure is required. Conclusions Intrusive memories are experienced by a large majority of adults with depression and may therefore be an important target for cognitive intervention. Larger scale measurement of clinical outcome is needed with identification of individual factors predicting treatment response

Neoliberal paternalism and paradoxical subjects: Confusion and contradiction in UK activation policy

The twin thrusts of neoliberal paternalism have in recent decades become fused elements of diverse reform agendas across the advanced economies, yet neoliberalism and paternalism present radically divergent and even contradictory views of the subject across the four key spaces of ontology, teleology, deontology and ascetics. These internal fractures in the conceptual and resulting policy framework of neoliberal paternalism present considerable risks around unintended policy mismatch across these four spaces or, alternatively, offer significant flexibility for deliberate mismatch and ‘storying’ by policy makers. This article traces these tensions in the context of the UK Coalition government’s approach to the unemployed and outlines a current policy approach to employment activation that is filled with ambiguity, inconsistency and contradiction in its understanding of the subject, the ‘problem’ and the policy ‘solution’
