Technology-Mediated Problematic Behaviors
No full textThe definition of maladaptive consumption has undergone a substantial revision in the past two decades, accommodating the changes that have affected, during the same period, global consumerism, primarily the advent of online media and electronic devices to access the internet. New technologies can affect important spheres of an individual’s life. The present chapter provides a review of the literature on technology-mediated problematic behaviors, focusing on internet use, online gambling, online gaming, and use of video streaming services. It reviews theory, evidence, and future trajectories with respect to the conceptualization, assessment, and unresolved questions in the field, in the attempt to summarize the available evidence and offer a perspective regarding this relatively new but extremely lively research area
Unique characterisability and learnability of temporal queries mediated by an ontology
Get PDFAlgorithms for learning database queries from examples and unique
characterisations of queries by examples are prominent starting points for developing automated support for query construction and explanation. We investigate how far recent results and techniques on learning and unique charac\-terisations of atemporal queries mediated by an ontology can be extended to temporal data and queries. Based on a systematic review of the relevant approaches in the atemporal case, we obtain general transfer results identifying conditions under which temporal queries composed of atemporal ones are (polynomially) learnable and uniquely characterisable
Stable isotope analyses of lacustrine chitinous invertebrate remains: analytical advances, challenges and potential
Get PDFThis review examines recent developments in the application of stable isotope analyses (δ18O, δ13C, δ15N, δD) to lacustrine invertebrate remains. These remains are ubiquitous in lacustrine sediments and thus provide an opportunity
to measure changes in stable isotope ratios across a range of timescales and environments and allow interpretive power beyond taxonomic studies. To date they have been relatively understudied in comparison to carbonate fossils and offer both opportunities and challenges and we explore both themes in this review. This review will explore improvements to analytical instrumentation and the opportunities that this presents, it will look at a range of new studies of the modern lacustrine environment and how these studies allow a more nuanced palaeoenvironmental approach. We review recent studies that have used these advancements in understanding to help to reveal new knowledge of past climates, environments and ecology. In addition, we explore new studies that help to elucidate the role of methane-derived carbon to lacustrine food webs and the drivers behind this, including new data to estimate the contribution of methane derived carbon to an arctic lake. We conclude that major progress is currently being made in invertebrate-isotope analyses, and we expect this to continue apace
Economic imaginaries and environmental regulation
Get PDFWhile literature has explored the influence of imagination and economic thought on (environmental) law, less attention has been paid to the influence of the economic imagination – specifically economic imaginaries – and their capacity to shape environmental regulation. Taking EU pesticides policy and regulation as a case study and drawing on theory regarding the performative power of imaginaries, this piece identifies economic imaginaries expressed in EU policy and demonstrates how those imaginaries have shaped that policy to pursue economic growth and competitiveness. It examines the evolution of a key piece of pesticides legislation and charts how establishing measures to pursue those economic goals gradually prevails, while providing for transparency – a crucial principle for supporting environmental protection – is deprioritised. It argues that these developments were driven by the EU’s economic imaginaries and shows how economic considerations can subtly and indirectly undermine environmental protection
When a crisis hits: an examination of the impact of the global financial crisis and the COVID-19 pandemic on financing for women entrepreneurs
Get PDFCrises have significant implications for entrepreneurs' businesses. Female entrepreneurs are often found to suffer from crises due to their marginalized positions. Despite the increasing research at the nexus of crisis, entrepreneurship, and gender, how a crisis may influence investors' funding decisions concerning female entrepreneurs and whether different macro crises bring with them different implications remain under-explored questions. Drawing on role congruity theory and the crisis and strategic decision-making literature, this paper proposes that macro crises can shake the perceived incongruity between traditional stereotypes of the female gender role and masculine stereotypes related to the entrepreneur's role, thereby affecting financing for female entrepreneurs. We further compare two specific crises having different associated implications: the global financial crisis (GFC) and the COVID-19 pandemic. We conducted two studies, one emphasizing experimental manipulation and the second based on observational data. We found consistent evidence that investors were more likely to invest in female-founded ventures after the GFC; however, the opposite phenomenon occurred after COVID-19. Our experiment demonstrates that changed perceptions of gender role incongruity are a critical underlying mechanism driving our results. Our research has implications for both the entrepreneurship literature and role congruity theory
One million years of climate-driven rock uplift rate variation on the Wasatch Fault revealed by fluvial topography
Get PDFDisplacement along the Wasatch Fault, Utah, has created the Wasatch Range. Owing to its topographic prominence, location on the eastern boundary of the Basin and Range, presently active fault slip, and proximity to Utah’s largest cities, the range and fault have garnered much attention. On the 102–103 year timescale, the behavior, displacement and seismic history of the Wasatch Fault has been well categorized in order to assess seismic hazard. On the 107 year timescale, the rock uplift rate history of the Wasatch range has also been resolved using thermochronometric data, owing to its importance in inferring the history of extension in the western US. However, little data exists that bridges the gap between these two timescales. Here, we infer an approximately 1 Ma rock uplift rate history from analysis of three river networks located in the center of the range. Our recovered rock uplift rate histories evidence periodic changes to rock uplift on the Wasatch Fault, that coincide with climate driven filling and unfilling of lakes in the Bonnneville Basin. To ensure our rock uplift rate histories are robust, we use field data and previously published cosmogenic 10Be erosion rate data to tightly constrain the erodibility parameter, and investigate an appropriate value for the slope exponent of the stream power model, n. We use our river network inversion to reconcile estimates of erodibility from a number of methodologies and show that the contrast between bedrock and bedload strength is an important factor that determines erodibility
Early intervention in psychosis for first episode psychotic mania: the experience of people diagnosed with bipolar disorder
Get PDFBackground: Early intervention for people diagnosed with bipolar disorder has been identified as a priority, but little is known about how existing early intervention services are experienced by this group or could be tailored to their needs. Aims: This study examined the experience of early intervention in psychosis (EIP) services for people diagnosed with bipolar disorder, following first episode psychotic mania. Method: Semi-structured interviews were conducted with 11 adults in EIP services and analysed using Interpretative Phenomenological Analysis. Results: One superordinate theme was formed, Rebuilding within EIP service, consisting of five subthemes: i) Piecing together episode through talking to staff; ii) Exploring other perspectives during CBT; iii) Empowered through shared decision-making; iv) Reconsidering future and purpose; v) Service as safety-net. EIP provision was pivotal in helping participants understand their episode, adjust their perspective, build confidence and progress. Conclusions: Aspects of the service that were valued, including person-centred relationships with staff, shared decision-making and the development of motivation and opportunities, reflect key principles of mental health care for young people following first episode psychosis. Furthermore, findings point to elements that may be particularly relevant to early intervention following first episode psychotic mania including managing mood escalation and individualised approaches to goals
Clinical and cost-effectiveness of an adapted intervention for preschoolers with moderate to severe intellectual disabilities displaying behaviours that challenge: the EPICC-ID RCT
Get PDFBackground: Stepping Stones Triple P is an adapted intervention for parents of young children with developmental disabilities who display behaviours that challenge, aiming at teaching positive parenting techniques and promoting a positive parent–child relationship.
Objective: To evaluate the clinical and cost-effectiveness of level 4 Stepping Stones Triple P in reducing behaviours that challenge in children with moderate to severe intellectual disabilities.
Design, setting, participants: A parallel two-arm pragmatic multisite single-blind randomised controlled trial recruited a total of 261 dyads (parent and child). The children were aged 30–59 months and had moderate to severe intellectual disabilities. Participants were randomised, using a 3 : 2 allocation ratio, into the intervention arm (Stepping Stones Triple P; n = 155) or treatment as usual arm (n = 106). Participants were recruited from four study sites in Blackpool, North and South London and Newcastle.
Intervention: Level 4 Stepping Stones Triple P consists of six group sessions and three individual phone or face-to-face contacts over 9 weeks. These were changed to remote sessions after 16 March 2020 due to the coronavirus disease 2019 pandemic.
Main outcome measure: The primary outcome measure was the parent-reported Child Behaviour Checklist, which assesses the severity of behaviours that challenge.
Results: We found a small non-significant difference in the mean Child Behaviour Checklist scores (−4.23, 95% CI −9.98 to 1.52, p = 0.146) in the intervention arm compared to treatment as usual at 12 months. Per protocol and complier average causal effect sensitivity analyses, which took into consideration the number of sessions attended, showed the Child Behaviour Checklist mean score difference at 12 months was lower in the intervention arm by −10.77 (95% CI −19.12 to −2.42, p = 0.014) and −11.53 (95% CI −26.97 to 3.91, p = 0.143), respectively. The Child Behaviour Checklist mean score difference between participants who were recruited before and after the coronavirus disease 2019 pandemic was estimated as −7.12 (95% CI −13.44 to −0.81) and 7.61 (95% CI −5.43 to 20.64), respectively (p = 0.046), suggesting that any effect pre-pandemic may have reversed during the pandemic. There were no differences in all secondary measures. Stepping Stones Triple P is probably value for money to deliver (−£1057.88; 95% CI −£3218.6 to −£46.67), but decisions to roll this out as an alternative to existing parenting interventions or treatment as usual may be dependent on policymaker willingness to invest in early interventions to reduce behaviours that challenge. Parents reported the intervention boosted their confidence and skills, and the group format enabled them to learn from others and benefit from peer support. There were 20 serious adverse events reported during the study, but none were associated with the intervention.
Limitations: There were low attendance rates in the Stepping Stones Triple P arm, as well as the coronavirus disease 2019-related challenges with recruitment and delivery of the intervention.
Conclusions: Level 4 Stepping Stones Triple P did not reduce early onset behaviours that challenge in very young children with moderate to severe intellectual disabilities. However, there was an effect on child behaviours for those who received a sufficient dose of the intervention. There is a high probability of Stepping Stones Triple P being at least cost neutral and therefore worth considering as an early therapeutic option given the long-term consequences of behaviours that challenge on people and their social networks.
Future work: Further research should investigate the implementation of parenting groups for behaviours that challenge in this population, as well as the optimal mode of delivery to maximise engagement and subsequent outcomes
The day of reckoning: Seneca’s epistolary time
No full textBook synopsis: Temporalities, Texts, Ideologies provides a new analysis of the significance of time in Classical and early modern literature, demonstrating that literary temporality continually intervenes in questions of ontology, hierarchy and politics. Examining a diverse range of texts from Homeric epic to eighteenth-century poems on the Last Judgement, this collection of essays contends that temporality in literature sits at the heart of how authors from antiquity through to the early modern period understood and negotiated the structures that shaped their lives and may shape lives to come.
Approaching the topic through four themes, the essays in this volume highlight the ways in which time is construed as relational, contestable and politically inflected. The authors show that variations in temporalities enable texts to critique the interactions or tensions between tradition and change, agency and determinism, social system and individual experience. The result is a refreshing approach to literary figurations of time that responds to the recent 'temporal turn' in the humanities, engages with current critical trends (such as ontological analysis and ecological criticism), and opens up an exciting new direction for future research on the connection between time, text, and context
