Investor sentiment and stock market returns: A story of night and day
Get PDFSome financial relations have been confirmed to be different overnight and intraday due to different clienteles. In this paper, we assess the impact of investor sentiment on stock market returns in 30 international stock markets overnight and intraday. At the global level, empirical evidence reveals a negative sentiment-return relation in both non-trading and trading hours, and the relation is stronger intraday than overnight, indicating that overnight traders are more rational than intraday traders. The separation between developed and emerging markets does not distort the negative relation or the stronger impact intraday. At the individual market level, results reveal a high degree of heterogeneity in the sentiment-return relation, in terms of both influence direction and magnitude. The heterogeneity can be explained by cross-market differences in cultural dimensions and market integrity, and notably, such influence varies across night and day, suggesting that the influence of the two aspects may be more complex than we used to theorize and therefore, future studies applying the cross-market analytical framework may take different clienteles into account
What might make nurses stay? A protocol for discrete choice experiments to understand NHS nurses’ preferences at early-career and late-career stages
Get PDFIntroduction: Like many countries, England has a national shortage of registered nurses. Employers strive to retain existing staff, to ease supply pressures. Disproportionate numbers of nurses leave the National Health Services (NHS) both early in their careers, and later, as they near retirement age. Research is needed to understand the job preferences of early-career and late-career nurses working in the NHS, so tailored policies can be developed to better retain these two groups. Methods and analysis: We will collect job preference data for early-career and late-career NHS nurses, respectively using two separate discrete choice experiments (DCEs). Findings from the literature, focus groups, academic experts and stakeholder discussions will be used to identify and select the DCE attributes (ie, job features) and levels. We will generate an orthogonal, fractional factorial design using the experimental software Ngene. The DCEs will be administered through online surveys distributed by the regulator Nursing and Midwifery Council. For each group, we expect to achieve a final sample of 2500 registered NHS nurses working in England. For early-career nurses, eligible participants will be registered nurses who graduated in the preceding 5 years (ie, 2019–2023). Eligible participants for the late-career survey will be registered nurses aged 55 years and above. We will use conditional and mixed logit models to analyse the data. Specifically, study 1 will estimate the job preferences of early-career nurses and the possible trade-offs. Study 2 will estimate the retirement preferences of late-career NHS nurses and the potential trade-offs. Ethics and dissemination: The research protocol was reviewed and approved by the host research organisation Ethics Committees Research Governance (University of Southampton, number 80610) (https://www.southampton.ac.uk/about/governance/regulations-policies/policies/ethics). The results will be disseminated via conference presentations, publications in peer-reviewed journals and annual reports to key stakeholders, the Department of Health and Social Care, and NHS England/Improvement retention leaders.

The first national subject benchmark statement for UK higher education in policing: the importance of effective partnership and collaboration
Get PDFPurpose The Quality Assurance Agency (QAA) for Higher Education in the UK focuses on maintaining, enhancing and standardising the quality of higher education. Of significant impact are the development of subject benchmark statements (SBS) by the QAA, which describe the type and content of study along with the academic standards expected of graduates in specific disciplines. Prior to 2022, the QAA did not have a SBS to which higher education policing programmes could be directly aligned. Design/methodology/approach Over 12-months, a SBS advisory group with representatives from higher education across England, Scotland, Wales and Northern Ireland, The College of Policing, QAA, Police Federation of England and Wales, and policing, worked in partnership to harness their collective professional experience and knowledge to create the first UK SBS for policing. Post publication of the SBS, permission was sought and granted from both the College of Policing and QAA for members of the advisory group to reflect in an article on their experiences of collaborating and working in partnership to achieve the SBS. FindingsThere is great importance of creating a shared vision and mutual trust, developed through open facilitated discussions, with representatives championing their cause and developing a collaborative and partnership approach to completing the SBS. Practical implications A collaborative and partnership approach is essential in developing and recognising the academic discipline of policing. This necessarily requires the joint development of initiatives, one of which is the coming together of higher education institutions, PSRBs and practitioner groups to collaborate and design QAA benchmark statements. Originality/valueThe SBS for policing is the first across the UK. The authors experiences can be used to assist others in their developments of similar subject specific benchmarking or academic quality standards. Social implications The SBS advisory group has further driven forward the emergence of policing as a recognised academic discipline to benefit multiple stakeholders
Assessing risk dimensions in dry port projects: prioritization, interdependence and heterogeneity
No full textPurpose We identify and further aggregate the most commonly engaged risk factors in dry port projects into dimensions. Noting the importance of developing a multi-perspective view of risk, we further assess the priority, interdependency and heterogeneity of the identified risk dimensions. Design/methodology/approach We identified 44 risk factors from the literature, which were aggregated via exploratory factor analysis (EFA) into 8 major risk dimensions. We employ a fuzzy-based decision-making trial and evaluation laboratory (DEMATEL) relationship map to articulate various relationships among the risk dimensions. Findings “Cost” emerged as the most important risk influencing the success of the dry port project, followed by “location,” “accessibility,” “infrastructural” and “operational,” which were also ranked prominently. Originality/value This study offers significant insight into the management of risk in dry port projects. By aggregating key risk factors into distinct dimensions, we develop a structured framework for effective risk assessment and management. The insights gleaned from the study extend globally, as it serves as a concrete knowledge base to understand potential barriers to successful dry port projects

Asymptotic analysis of detonation development at SI engine conditions using computational singular perturbation
Get PDFThe occurrence and intensity of the detonation phenomenon at spark-ignition (SI) engine conditions is investigated, with the objective to successfully predict super-knock and to elucidate the effect of kinetics and transport at the ignition front. The computational singular perturbation (CSP) framework is employed in order to investigate the chemical and transport mechanisms of deflagration and detonation cases in the context of 2D high-fidelity numerical simulations. The analysis revealed that the detonation development is characterised by: (i) stronger explosive dynamics and (ii) enhanced role of convection. The role of chemistry was also found to be pivotal to the detonation development which explained the stronger explosive character of the system, the latter being an indication of the system's reactivity. The role of convection was found to be enhanced at the edge of the detonating front. Moreover, the increased contribution of convection was found to be related mainly to heat convection. Remarkably, the detonation front was mainly characterised by dissipative and not explosive dynamics. Finally, diffusion was found to have negligible role to both examined cases
EMDR v. other psychological therapies for PTSD: a systematic review and individual participant data meta-analysis
Get PDFBackgroundThis systematic review and individual participant data meta-analysis (IPDMA) examined the overall effectiveness of eye movement desensitization and reprocessing (EMDR) in reducing posttraumatic stress disorder (PTSD) symptoms, achieving response and remission, and reducing treatment dropout among adults with PTSD compared to other psychological treatments. Additionally, we examined available participant-level moderators of the efficacy of EMDR.MethodsThis study included randomized controlled trials. Eligible studies were identified by a systematic search in PubMed, Embase, PsyclNFO, PTSDpubs, and CENTRAL. The target population was adults with above-threshold baseline PTSD symptoms. Trials were eligible if at least 70% of study participants had been diagnosed with PTSD using a structured clinical interview. Primary outcomes included PTSD symptom severity, treatment response, and PTSD remission. Treatment dropout was a secondary outcome. The systematic search retrieved 15 eligible randomized controlled trials (RCTs); 8 of these 15 were able to be included in this IPDMA (346 patients). Comparator treatments included relaxation therapy, emotional freedom technique, trauma-focused cognitive behavioral psychotherapies, and REM-desensitization.ResultsOne-stage IPDMA found no significant difference between EMDR and other psychological treatments in reducing PTSD symptom severity (β = −0.24), achieving response (β = 0.86), attaining remission (β = 1.05), or reducing treatment dropout rates (β = −0.25). Moderator analyses found unemployed participants receiving EMDR had higher PTSD symptom severity at the post-test, and males were more likely to drop out of EMDR treatment than females.ConclusionThe current study found no significant difference between EMDR and other psychological treatments. We found some indication of the moderating effects of gender and employment status
Practicalities of promoting practice‐based learning in end of life care for care home staff: Lessons from “online” supportive conversations and reflection sessions
Get PDFIntroduction: Deaths in care homes and “at home” are anticipated to account for a third of UK deaths by 2040. Currently, palliative and end of life care are not part of statutory training in care homes. Reflective practice is a tool that can facilitate practice‐based learning and support. Following a feasibly study to test “online” supportive conversations and reflection sessions (OSCaRS) to support care home staff in relation to death/dying during the first months of the COVID pandemic, a one‐year practice development follow‐up project was undertaken with the aim to create a team of NHS/specialist palliative care (SPC)‐based facilitators to lead and support OSCaRS provision in up to 50 care homes in one region in Scotland—the focus of this paper. Methods: Forty care home managers attended an on‐line session explaining the project, with a similar session held for 19 NHS/SPC‐based nurses external to care homes. Those interested in facilitating OSCaRS then attended three education sessions. Data collected: records of all activities; reflective notes on OSCaRS organised/delivered; a summary of each OSCaRS reflection/learning points; final interviews with NHS/SPC trainee facilitators. Results: A total of 19 NHS/SPC facilitators delivered one or more OSCaRS in 22 participating care homes. However, as of January 2022 only six trained facilitators remained active. Out of the 158 OSCaRS arranged, 96 took place with a total of 262 staff attending. There were three important aspects that emerged: the role, remit, and resources of NHS/SPC supporting OSCaRS; requirements within care homes for establishing OSCaRS; and, the practice‐based learning topics discussed at each OSCaRS. Conclusion: Attempts to establish a team of NHS/SPC facilitators to lead OSCaRS highlights that end of life care education in care homes does not clearly fall within the contractual remit of either group or risks being missed due to more pressing priorities
Re-politicising Anti-trafficking: Migration, Labour, and the War in Ukraine
Get PDFDrawing on multi-method research, this article demonstrates that the risks of large-scale trafficking due to the war in Ukraine were mitigated by granting Ukrainians more extensive rights than typically afforded to refugees. This shows the advantages of rights-based approaches to migration and labour exploitation. We draw on Bakhtin’s and Zizek’s work on the carnivalesque to argue that mainstream anti-trafficking initiatives – which are depoliticised and able to win support and funding from across the political spectrum –often serve merely as theatrical and distracting sideshows diverting attention from more impactful activities and the normalised exploitation within capitalism. However, avoiding trafficking is insufficient if Ukrainian citizens and residents still endure exploitative conditions. A weakened legal framework for workers’ rights within Ukraine alongside inadequate labour protections across Europe have facilitated such exploitation. In contrast to the depoliticised stance of the antitrafficking industry, this article concludes that more explicitly political actions supporting migrants' rights, workers' rights, and access to welfare and public services will not only more effectively challenge trafficking but also prevent other exploitation of migrants
Exploring the role of socioeconomic status and psychological characteristics on talent development in an English soccer academy
Get PDFSocial factors and psychological characteristics can influence selection and development in talent pathways. However, the interaction between these two factors is relatively unknown. The aim of this study was to investigate the implications of socioeconomic status and psychological characteristics in English academy soccer players (n = 58; aged 11 to 16 years). To assess socioeconomic status, participants’ home postcodes were coded according to each individual’s social classification and credit rating, applying the UK General Registrar Classification system and CameoTM geodemographic database, respectively. Participants also completed the six factor Psychological Characteristics for Developing Excellence Questionnaire (PCDEQ). A classification of ‘higher-potentials’ (n = 19) and ‘lower-potentials’ (n = 19) were applied through coach potential rankings. Data were standardised using z-scores to eliminate age bias and data were analysed using independent sample t-tests. Results showed that higher-potentials derived from families with significantly lower social classifications (p = 0.014) and reported higher levels for PCDEQ Factor 3 (coping with performance and developmental pressures) (p = 0.007) compared to lower-potentials. This study can be used to support the impetus for researchers and practitioners to consider the role of social factors and psychological characteristics when selecting and developing sporting talent. For example, facilitating player-centred development within an academy and, where necessary, providing individuals with additional support
