This analysis is performed on proton–proton collision data collected with the CMS detector at the CERN LHC during 2016–2018 at a center-of-mass energy of 13 TeV, and corresponds to an integrated luminosity of 138fb^{-1}. The different-flavor dilepton (eμ) final state is analyzed, with dedicated categories targeting gluon fusion, electroweak vector boson fusion, and associated production with a W or Z boson. Kinematic information from associated jets is combined using matrix element techniques to increase the sensitivity to anomalous effects at the production vertex. A simultaneous measurement of four Higgs boson couplings to electroweak vector bosons is performed in the framework of a standard model effective field theory. All measurements are consistent with the expectations for the standard model Higgs boson and constraints are set on the fractional contribution of the anomalous couplings to the Higgs boson production cross section.SCOAP3

The optimal cycle light configuration for maximizing cyclists’ conspicuity to drivers is not clear. Advances in sensor technology has led to the development of ‘reactive’ cycle lights that detect changes in the environment and consequently increase their flashing speed and brightness in risky situations – for example, when a rearward car is approaching – but no research has examined the effect of such lights on driver perception. The aim of the present study is to compare different cycle light configurations, including ‘reactive’ light technology, on drivers’ ability to detect cyclists and estimate their proximity. We recruited 32 drivers to participate in two experiments, in which they viewed life-size real-world stimuli filmed from a driver’s perspective in daytime and at dusk. The footage showed a cyclist on a bicycle with a rear light mounted on the seat post, in various configurations: static light, steady flashing, reactive flashing and no light. In Experiment 1, the drivers were required to detect the presence or absence of a cyclist on the road ahead as quickly as possible. In Experiment 2, they were required to estimate the distance of the cyclist from their vehicle, and to rate their confidence in their estimates. Experiment 1 revealed that drivers were quicker to detect the cyclist’s presence in all rear cycle light conditions relative to the no light condition, but there were no differences in speed or accuracy across rear light conditions. Experiment 2 showed that drivers were more accurate in estimating the cyclist’s proximity in the steady flashing and reactive flashing conditions, compared to static and no light conditions. Drivers were also more confident in their judgements in all rear light conditions compared to the no light condition. In conclusion, flashing rear cycle lights, regardless of reactive technology, enhanced drivers’ perception of a cyclist ahead, notably in terms of their judgements of distance to that cyclist. Further investigation is needed to fully understand the impact of cycle light technology on driver perception, as well as the use of drivers’ distance-to-cyclist estimates as an index of cyclists’ cognitive conspicuity.Brunel Innovation Voucher Schem
From managerialism to toxic leadership: The moderating effect of ethical climate in the healthcare sector
Get PDFA hegemonic neoliberal ideology dominates all areas of work in Turkey, including healthcare. Though neoliberalism has been studied extensively from the perspective of meaning, values, and processes, managerial and leadership behavior dynamics require further research. This study analyzes the relationship between managerialism, toxic leadership, and ethical climate in an industry swept up by untamed neoliberalism, particularly in a nation where employment and human rights are ceremoniously protected. Through an analysis of medical doctors working in 207 public and private university hospitals in Turkey, we explored the role of managerialism and four distinct ethical climate types, resulting in the emergence of toxic leadership behaviors during the global pandemic. We theorize the extent to which toxic leaders emerge from managerialism. We further explain why the hegemonic Turkish leadership culture thrives in toxic behaviors such as paternalism, fealty, ingratiation, nepotism, and cronyism in the context of neoliberal expansion
Measuring line tension: Thermodynamic integration during detachment of a molecular dynamics droplet
Get PDFData Availability: The data that support the findings of this study are available from the corresponding author upon reasonable request.Supplementary Material: The supplementary material contains how to evaluate the average Ac of the droplet area A for various η values and its uncertainty δAc used in Eq. (28). It is available online at: https://pubs.aip.org/aip/jcp/article/160/22/224502/3297315/Measuring-line-tension-Thermodynamic-integration#89149592 and at: https://ndownloader.figstatic.com/files/46499926 .The contact line (CL) is where solid, liquid, and vapor phases meet, and Young’s equation describes the macroscopic force balance of the interfacial tensions between these three phases. These interfacial tensions are related to the nanoscale stress inhomogeneity appearing around the interface, and for curved CLs, e.g., a three-dimensional droplet, another force known as the line tension must be included in Young’s equation. The line tension has units of force, acting parallel to the CL, and is required to incorporate the extra stress inhomogeneity around the CL into the force balance. Considering this feature, Bey et al. [J. Chem. Phys. 152, 094707 (2020)] reported a mechanical approach to extract the value of line tension τℓ from molecular dynamics (MD) simulations. In this study, we show a novel thermodynamics interpretation of the line tension as the free energy per CL length, and based on this interpretation, through MD simulations of a quasi-static detachment process of a quasi-two-dimensional droplet from a solid surface, we obtained the value τℓ as a function of the contact angle. The simulation scheme is considered to be an extension of a thermodynamic integration method, previously used to calculate the solid–liquid and solid–vapor interfacial tensions through a detachment process, extended here to the three-phase system. The obtained value agreed well with the result by Bey et al. and showed the validity of thermodynamic integration at the three-phase interface.T.O., H.O., H.K., and Y.Y. were supported by JSPS KAKENHI under Grant Nos.

Influence of rapid high-temperature processing on the interface of CF/PEEK, a quick and effective method for enhancing the IFSS
Get PDFData availability: Data will be made available on request.The work was enabled through, and undertaken at, the National Structural Integrity Research Centre (NSIRC), a postgraduate engineering facility for industry-led research into structural integrity established and managed by TWI through a network of both national and international Universities.This study explores the effect of rapid high-temperature processing on the interface of carbon fibre (CF) reinforced poly-ether-ether-ketone (PEEK). Specimens that have been thermally treated at slower and faster heating rates and specimens that have not been post-manufacturing treated (virgin) are examined with single fibre pull-out tests. A comparison between their interfacial shear strength (IFSS) and their failure modes takes place. Scanning electron microscopy is used to assess the surface morphology of the thermally treated specimens, and partly cross-polarised microscopy is employed to investigate the development of transcrystallinity. Furthermore, to identify the extent of thermal degradation the specimens are examined with attenuated total reflection Fourier transform infrared spectroscopy. At faster heating rates, an improved interfacial adhesion up to 25% is found at temperatures where a low-level thermal damage is induced. At higher temperatures and despite the increased thermal damage, an IFSS increase of up to 10% is still identified. This is due to the beneficial formation of thermal residual stresses upon high-temperature processing, and overall, especially rapid high-temperature processing could effectively serve for enhancing the interface properties of CF/PEEK.TW
How do inclusive leaders emerge? A theory-based model
Get PDFDespite recent theoretical developments examining the emergence of several types of leadership, there is a paucity of research on the emergence of inclusive leaders. We sought to address this gap by proposing a theory-based conceptual model. We identify a paradox in leader emergence: Although there is evidence that inclusive leaders can improve organizational effectiveness, those who influence decisions about leader selection, both formal and informal, often overlook this evidence and instead select leaders who do not practice inclusion. Integrating expectation states theory and implicit leadership theory to explain leadership emergence, with social identity theory and social comparison theory to explain inclusion, we propose a conceptual model culminating with four propositions. The model suggests practices that can support inclusive leadership and how inclusive leadership can improve organizational effectiveness and employee well-being. We conclude with implications for policies to promote inclusive leadership emergence and propose avenues for future research.The author(s) received no financial support for the research, authorship, and/or publication of this article

However, further detail on the qualitative data that support findings of this study are available on request from the corresponding author ([email protected]). Mixed methods data is presented throughout this manuscript and associated supplementary materials.Supplementary Material is available online at: https://www.sciencedirect.com/science/article/pii/S2468024924019594#appsec2 /Introduction:
The Kidney BEAM randomized controlled trial reported clinically meaningful and statistically significant improvements in mental health-related quality of life (HRQoL), physical function (sit-to-stand-60, but not the physical component of HRQoL) and patient activation after a 12-week physical activity digital health intervention (DHI). This study explores factors that contributed to the effectiveness of Kidney BEAM through mixed methods analyses.
Methods:
Quantitative data analysis was obtained from the recently published primary manuscript. Participants from the Kidney BEAM trial intervention group (n = 30) completed individualized semistructured interviews after the 12-week DHI. Interviews were analyzed using the framework method with inductive and deductive coding. Quantitative and qualitative data collection and analyses occurred concurrently, and independently, before combining using a mixed methods analysis with joint displays to triangulate datasets and further explore the primary findings.
Results:
The integrated mixed methods analyses facilitated explanation of the primary findings. The Kidney BEAM intervention was shown to have mental and physical wellbeing benefits and enhanced self-management in this cohort of people living with chronic kidney disease (CKD). Elements that contributed to the effectiveness of the intervention were reported, including the different functional levels and gradual progression of the program, shared lived experiences with other participants, self-monitoring, the sense of achievement, taking back control of their health, moving beyond medications, and feeling safe and confident to exercise.
Conclusion:
Elements of the Kidney BEAM intervention that contributed to the main quantitative trial findings were identified. This will allow researchers and practitioners to maximize the effectiveness of DHIs to enhance healthy behaviors in people living with CKD.This study was funded by a grant from Kidney Research UK.

What can we learn from service model analysis? An application in the government export finance sector
Get PDFThe service model approach, like business models in the private sector, is gaining increasing attention in public management literature. In line with this evolving discourse, our study analyzes service models in government export promotion. By exploring the use of service models and discussing key developments, we shed light on the diverse application of service models in the context of officially supported export credits – an under-researched field in which a lot of innovation is happening. We observe a limited number of traditional service models with significant relevance. In addition, our findings suggest a rising diversity that signifies innovation and the broadening scope of activities. We also uncover the underlying motivations and practical experiences associated with their implementation and provide valuable insights into the benefits they offer.The author(s) received no financial support for the research, authorship, and/or publication of this article
Navigating geopolitical and trade megatrends: Public export finance in a world of change
Get PDFData Availability Statement: The data that support the findings of this study are available on request from the corresponding author. The data are not publicly available due to privacy or ethical restrictions.Ensuring exporters can access finance is critical for governments as they look to encourage trade and drive economic growth. However, firms face challenges in securing export finance and trade credit insurance as geopolitical and trade megatrends lead to increased political, market and credit risks. In a dynamic global landscape, the role of export credit agencies (ECAs) has never been more important. Based on the ‘Futures Triangle’ analytical framework and drawing on qualitative data from 35 semi-structured interviews and expert discussions using thematic analysis, this research assesses the implications of key megatrends for ECAs. It presents new insights into the impact on strategies, products and operations: The evolution of mandates towards a ‘growth promoter’ in a ‘whole-of-government’ approach, the necessity to introduce new products and the need to balance multiple priorities such as export growth, support for small and medium-sized enterprises (SMEs), inclusive trade, climate action and impact on developing markets. The recommendations are intended to help policymakers and public finance practitioners understand and respond strategically to global changes.The research leading to this work has been funded by UK Export Finance.
