The delivery of creative socially prescribed activities for people with serious mental health needs during lockdown: Learning about remote, digital and hybrid delivery.

Social prescribing interventions connect mental health service users to community resources, to support physical and mental wellbeing and promote recovery. COVID-19 restrictions impacted the delivery of socially prescribed activities, preventing face to face contact for long periods. The aim of this study was to understand how Voluntary Community and Social Enterprise (VCSE) organisations working with a local NHS mental health Trust responded to the challenges of social distancing during the COVID-19 pandemic. This understanding will be used to make recommendations for future practice, post-lockdown. Using a convergent mixed methods design, we surveyed VCSE providers of socially prescribed activities intended to be accessible and appropriate for people with severe mental health needs. Follow-up interviews explored further how they adapted during the first year of the pandemic, the challenges they faced, and how they sought to overcome them. The survey and interview data were analysed separately and then compared to identify convergent and divergent findings. Twenty VCSE representatives completed the survey which provided a snapshot of changes in levels of connection and numbers reached during lockdown. Of 20 survey respondents, 11 participated in follow-up interviews. Interviews revealed that lockdown necessitated rapid change and responsive adaptation; activities were limited by resource, funding, safeguarding and government restrictions; no single format suited all group members; connection was key; and impact was difficult to gauge. VCSE organisations commissioned to deliver creative socially prescribed activities during the pandemic rapidly adapted their offer to comply with government restrictions. Responsive changes were made, and new knowledge and skills were gained. Drawing on experiences during lockdown, VCSE organisations should develop bespoke knowledge, skills and practices to engage service users in future hybrid delivery of arts, sports, cultural and creative community activities, and to ensure that digital activities offer an equivalent degree of connection to face-to-face ones. Additionally, more effective methods of gaining feedback about patient experience of hybrid delivery is needed.

Uncertainty of scintillator-based field-output factor measurements in MR-Linacs with the two-channel chromatic stem removal technique

Current international protocols such as the IAEA/AAPM TRS-483 for small field dosimetry do not include recommendations for measurements in strong magnetic fields as found in MR-Linacs (i.e. megavoltage x-ray radiotherapy units with built-in magnetic resonance imaging). A EURAMET research project was therefore launched to support the traceability of such measurements and to contribute to the metrological basis for future recommendations. Given the high degree of water equivalence and the small size of fiber-coupled plastic scintillators, one objective of the project was to study the suitability of this detector type for dosimetry in MR-Linacs and to demonstrate their use in a clinical environment. This manuscript reports results of that work. A protocol for measuring field output factors with plastic scintillation detectors was developed. The protocol is based on calibration of the scintillators directly in a water phantom positioned in the MR-Linac rather than in a water-equivalent solid phantom as has been a common technique for conventional linacs. A detailed uncertainty budget was established involving all known sources of uncertainty including the systematic influence of light attenuation through the fiber when measuring in different field sizes. The protocol was used to measure field output factors at five MR-Linac's (four Viewray MRIdian's and one Elekta Unity). The protocol showed a high level of robustness leading to a less than 0.3 % deviation between field output factors calculated based on calibration data obtained before or after the field-output factor measurements. The correction for light attenuation was less than 0.4 % for all fields measured but showed a systematic offset, with larger corrections needed for small field sizes.This robustness of the protocol was further demonstrated by the closeness of agreement (agreement within uncertainty) for field-output factor measurements with two different scintillators (BCF-12 and BCF-60) for square fields (size: 0.83 cm × 0.83 cm or larger) in four nominally identical Viewray MRIdian's. To test the accuracy of the scintillator measurements, the system was used for characterization of a PTW 60019 micro diamond detector in a Viewray MRIdian. Scintillator based correction factors for output factor measurements with the micro diamond detector were found to be in agreement with independent Monte-Carlo computations. The study therefore supports that plastic scintillation detectors are an excellent option for measuring field output factors in MR-Linacs.

Translation Equivalence Degrees among Indonesian EFL Undergraduate Students

PurposeThe way to produce an equivalent translation text appears hard that every translation work should engage with diverse language and cultural systems. The issues are expected to affect both translation students and professional translators. Therefore, this current work aims to discover in-depth information about translation equivalence degrees among Indonesian EFL undergraduate students.MethodThis study employed qualitative content analysis. The research data included documentation of the translation texts from English into the Indonesian language, which resulted in 22 students majoring in English education at a public university in Banten Province, Indonesia. The source language texts were derived from the news-item texts published in national newspapers. The data analysis procedure comprised comparing the two texts, classifying, discussing, drawing conclusions, and making interpretations. Results/findingsThe study of the translation texts revealed that 11 texts (50%) referred to near-optimal translation, six texts (27%) to partial translation, and five texts (23%) to poor translation.ConclusionGiven that none of the students' translation outputs achieved the optimal equivalency; this conclusion suggests that students' translation knowledge and skills still need to be improved by regular practice and discussion at each translation course meeting.

Experimental and numerical study on the blast performance of the corrugated double steel plate concrete composite wallboard under blast loads

The corrugated double steel plate concrete composite wallboard (CDSCW) exhibits superior axial compressive load-bearing capacity, lateral flexural stiffness, impact resistance, and seismic performance compared to the traditional reinforced concrete wallboard and plane double steel plate concrete composite wallboard (PDSCW). Therefore, it has great potential application in offshore engineering and military engineering. This study designs and fabricates two types of CDSCW specimens. Firstly, a comparative analysis is conducted to examine the damage patterns and dynamic responses of the two specimens under near-field explosion experiments. Secondly, the damage mechanisms and explosion response of CDSCW and PDSCW subjected to close-in explosions are numerically investigated by using ANSYS/LS-DYNA, and the results are then compared with experimental findings. Parameter analysis is performed to assess the influence of concrete thickness, steel plate thickness, and explosive charge on the blast resistance of CDSCWs. Furthermore, a nonlinear resistance equation and an equivalent single degree of freedom (ESDOF) theoretical model for simply supported beams is established to predict the dynamic response of CDSCWs under near-blast loads. This theoretical model considers the constitutive model of bilinear materials and the effect of plastic hinges. The reliability of the proposed theoretical model is verified by comparing the residual deflection of CDSCWs obtained from explosion tests with validated numerical simulation results. The results demonstrate that the CDSCWs, with the same concrete and component dimensions (length, width), exhibit greater flexural stiffness and superior energy dissipation capacity subjected to close-in explosion. Moreover, their blast resistance significantly surpasses that of PDSCWs. In particular, an increase in corrugation depth effectively improves the blast resistance of CDSCWs. The dynamic response equations, based on the established elastic-plastic model and primarily considering bending deformation of the components, precisely predict the dynamic response of simply supported CDSCWs under near-blast loads. consequently, these findings can provide a robust foundation for further research and the design of blast-resistant structures.

Dynamic behaviors of unreinforced and spray polyurea retrofitted brick masonry infill walls under blast loads: Shock tube test and analyses

Unreinforced masonry infill walls (MIWs) are prone to crack, fragment, and even collapse under blast loads, threatening the safety of building structures, as well as the inside occupants and equipment. Spray polyurea (SPUA) has been proven to be an excellent retrofitted material for MIWs to improve their blast resistance. Aiming to study the dynamic behaviors of brick MIWs under far-field range blast loads, the successive blast tests on seven unreinforced and SPUA-retrofitted brick MIWs with different thicknesses and boundary constraints were first carried out based on the developed compressed air-driven large cross-section (3m×3 m) shock tube. It was indicated that the blast resistance of MIWs significantly improved by increasing wall thickness and strengthening boundary constraint; SPUA coating can improve the blast resistance of MIWs and effectively suppress the debris generation and splash. Then, the equivalent single degree of freedom model based theoretical calculation and the simplified micro-model based numerical simulation methods previously established by authors were briefly introduced. Additionally, the dynamic behaviors of seven examined MIWs were further predicted and compared with test results, which verified the applicability of theoretical calculation and numerical simulation methods. Finally, the improved damage and failure evaluation criteria of unreinforced and SPUA-retrofitted MIWs were given, and the charge weight and standoff distance diagrams of typical MIWs were proposed based on the validated theoretical and numerical methods as well as the improved criteria, which would provide a helpful reference for blast-resistant evaluation and retrofitted design of brick MIWs.

Is more always better? The influences of guanxi beliefs, participative decision-making and perceived organizational politics on HK and US nurses’ job satisfaction

PurposeDrawing on the challenge–hindrance stressor framework and the “too-much-of-a-good-thing” principle, this study examined the curvilinear effects of two emic social challenge stressors (guanxi beliefs and participative decision-making (PDM)) and the moderating effect of an etic social hindrance stressor (perceived organizational politics) on Hong Kong and United States nurses’ job satisfaction.Design/methodology/approachA quantitative survey method was implemented, with the data provided by 355 Hong Kong nurses and 116 United States nurses. Structural equation modeling was used to examine the degree of measurement equivalence across Hong Kong and US nurses. The proposed model and the research questions were tested using nonlinear structural equation modeling analyses.FindingsThe results show that while guanxi beliefs only showed an inverted U-shaped relation on Hong Kong nurses’ job satisfaction, PDM had an inverted U-shaped relation with both Hong Kong and United States nurses’ job satisfaction. The authors also found that Hong Kong nurses experienced the highest job satisfaction when their guanxi beliefs and perceived organization politics were both high.Research limitations/implicationsThe results add to the comprehension of the nuances of the often-held assumption of linearity in organizational sciences and support the speculation of social stressors-outcomes linkages.Practical implicationsManagers need to recognize that while the nurturing and development of effective relationships with employees via social interaction are important, managers also need to be aware that too much guanxi and PDM may lead employees to feel overwhelmed with expectations of reciprocity and reconciliation to such an extent that they suffer adverse outcomes and become dissatisfied with their jobs.Originality/valueFirst, the authors found that influences of guanxi beliefs and PDM are not purely linear and that previous research may have neglected the curvilinear nature of their influences on job satisfaction. Second, the authors echo researchers’ call to consider an organization’s political context to fully understand employees’ attitudes and reactions toward social interactions at work. Third, the authors examine boundary conditions of curvilinear relationships to understand the delicate dynamics.

Pregnancy-Associated Firearm Mortality in the U.S., 2008–2019

IntroductionThis study analyzed the contribution of firearms to pregnancy-associated mortality from homicide and suicide. MethodsThis was a retrospective cohort study using the CDC's National Violent Death Reporting System from 2008 – 2019. Women aged 15-44 years who died by suicide (intentional self-harm) and homicide where a firearm was involved were included. Persons without known pregnancy status were excluded. Pregnancy-associated deaths were defined as those that occurred during pregnancy or within 1 year of pregnancy (early and late postpartum). Sociodemographic characteristics, social, and circumstantial differences were compared in pregnancy-associated and non-pregnant deaths. Data analysis was conducted in 2022 – 2023. ResultsA total of 1,803 homicide and 1,929 suicide deaths from firearms were included. Twenty-two percent (n=388) and 11% (n=212) of firearm homicides and suicides respectively, were pregnancy-associated. Victims of pregnancy associated homicide were predominantly Black (54.8%), single (76%), and had high school diploma or equivalent degree (41.2%). Victims of pregnancy-associated suicide were predominantly White (80.5%). Among pregnancy-associated homicides and suicides, deaths occurred more frequently during pregnancy (63.4% and 40.3%). Compared to non-pregnancy associated homicides, pregnancy-associated homicides more frequently occurred in the victim's home (51.5% vs 46.7%, p=0.02) and was related to ongoing conflict or violence between a current or former partner (61.6% vs 51.9%, p < 0.001). Compared to non-pregnancy-associated suicide, pregnancy-associated suicides more frequently occurred in those who experienced intimate partner violence within a month of death (4.2% vs 1.3%, p=0.005). ConclusionsWhile there are differences in demographic characteristics between victims, interpersonal violence is associated with both pregnancy-associated homicides and suicides where a firearm was involved.

Adaptation of the Australian National University Alzheimer's Disease Risk Index-Short Form (ANU-ADRI-SF) into Turkish.

The 'Australian National University Alzheimer's Disease Risk Index' (ANU-ADRI) assesses the risk of developing Alzheimer's disease (AD) and is a potential tool for its prevention. The aim of this study is to adapt the ANU-ADRI-SF (the short version of ANU-ADRI) into the Turkish language and Turkish cultural context. The study was methodological and involved the translation and intercultural adaptation of the ANU-ADRI-SF into the Turkish language. The study included 384 community-based participants from a province in the Western Black Sea Region of Türkiye. Data was collected via an online form prepared using Google Forms. The index was translated from its original language, English, into Turkish and then retranslated to English by bilingual translators. It was then reviewed and evaluated for possible issues related to translation and degrees of equivalence. When TR-ANU-ADRI-SF levels were compared according to sex, the mean risk scores were found to be 11.25 ± 7.02 for males and 11.69 ± 7.99 for females. After cross-cultural adaptation, the TR-ANU-ADRI-SF was conceptually intelligible to Turkish adults. The TR-ANU-ADRI-SF is a valid and reliable AD risk assessment tool. Given the increase in AD and its impact on people's health, there is a great need for strategies to be implemented by health professionals to improve the lifestyle of the adult population. For use in conjunction with these strategies, a localised AD risk assessment tool that can be applied by clinicians or by individual patients has been adapted and introduced to the Turkish literature.

Practice-Based Learning in Aesthetic Medicine: Assessing Scientific Literacy Among Cosmetic Practitioners.

The field of aesthetic medicine has expanded substantially in the past decade, with significant practitioner diversification and departure from core-specialty supervision. The increased autonomy of nonphysician practitioners in a rapidly evolving field has raised accentuated the importance of scientific literacy and practice-based learning standards in the delivery of aesthetic medical care. To assess the degree of scientific literacy among aesthetic medicine practitioners of different educational and training backgrounds in the United States and abroad. A cross-sectional survey of 52 national and international aesthetic medicine practitioners employing a validated, 28-item, scientific literacy tool. The average score for all participants was 76% (SD = 18%, range = 43%-100%). Physician practitioners scored higher in all competencies compared non-physicians (86% vs 68%, p < 0.001), with a greater discrepancy among US practitioners (95% vs 71%, p < 0.001). Competencies relating to identification of bias/confounding variables, graphical data representation, and statistical inference/correlation showed the lowest proficiency. Practitioners with a doctorate or equivalent degree were significantly more likely to report frequent engagement with medical literature than non-physicians ( p = 0.02). There exists a significant disparity in scientific literacy between physician and nonphysician aesthetic medicine practitioners. This gap underscores the need for enhanced educational programs and continuous professional development to ensure safe and effective patient care in the evolving field of aesthetic medicine.

Regularities of formation of microstructure and mechanical properties of copper m1 under combined plastic deformation

The influence of combined plastic deformation, including methods of intense plastic deformation and traditional metal forming, on the structure and mechanical properties of M1 copper was studied. It has been shown that combined processing helps to increase the dimensional uniformity of hardness across the cross-section of the workpiece and contributes to the refinement of microstructure elements. Thus, with an increase in the equivalent degree of deformation, the level of mechanical properties of M1 copper increases accordingly.

Comparison of the standards for absorbed dose to water of the IAEA and the KRISS, Korea in accelerator photon beams

A bilateral comparison was conducted between the International Atomic Energy Agency (IAEA) and the Korea Research Institute of Standards and Science (KRISS) to measure the absorbed dose to water in accelerator photon beams. KRISS served as a linking laboratory to compare the IAEA standard with the key comparison reference value (KCRV) of the BIPM.RI(I)–K6 program, in which KRISS participated in 2017.Two ionization chambers from the IAEA were used as transfer instruments for the comparison. Both laboratories measured the calibration coefficients of these instruments and calculated the ratios. The ratio of the KRISS standard to the KCRV was applied to obtain the degree of equivalence of the IAEA, along with its uncertainty. The largest deviation of the IAEA measurement from the KCRV was 3.4 mGy/Gy, significantly smaller than the expanded uncertainty of 10.7 mGy/Gy (k = 2, 95% level of confidence).This study demonstrates the equivalence of IAEA's measurement standard for accelerator photon beams to other primary standard dosimetry laboratories. It provides evidence for the satisfactory operation of IAEA's quality management system and enhances the international credibility of the IAEA SSDL network, particularly in high-energy accelerator photon beams from linear accelerators.

Multi-kilowatt cw laser power measurement comparison between national standards

We present here the first comparison between National Metrology Institutes of high accuracy continuous wave optical power measurements in the kilowatt regime. The National Institute of Standards and Technology (NIST) performed measurements with a power meter relying on photon momentum. The Physikalisch-Technische Bundesanstalt (PTB) performed measurements with a modified off-the-shelf thermal power meter. The non-absorbing photon momentum measurement approach permits the two power meters to measure the same laser beam optical path simultaneously, resulting in a direct comparison of the meters supported by an optical system to accommodate differences in instrument settling times. The results show agreement within the expanded uncertainties for each instrument. NIST and PTB illustrate a degree of equivalence of 0.49% with an expanded uncertainty of 1.37% (k = 2) for an average result across all power levels.

Research of stress-strain state of the reinforcement profile during the stretching–bending–rebending (cold stretching)

The Cold Stretching method (SBR: stretching, bending with rebending), widely used abroad, makes it possible to implement low strain degrees in high-performance reinforcement production lines, increasing the level of reinforcement mechanical proprieties till A500. The process consists of a combination of stretching the reinforcement at a controlled degree of cold plastic deformation with the addition of alternating bending elements in special roller systems. The paper presents the results of computer finite element modeling in SIMULIA Abaqus complex of stress-strain state of periodic profile reinforcement in the process of SBR. The simulation results showed that during the SBR process the reinforcement receives an equivalent degree of compressive and tensile strain when passing through each subsequent roller, that is, during the transition between groups of rollers and individual rollers in a pair, each section of the profile receives a tensile load commensurate in modulus with the subsequent compression load. To verify this observation in the industrial conditions of OJSC MMK-Metiz, samples of the studied A400 reinforcement were selected in the hot-rolled state and after the SBR process. The study showed that the geometric parameters of the profile remained within normalized limits and no protrusion integrity violations were observed, which confirms the modeling results.

Effects of repeated low-level red-light therapy on macular retinal thickness and microvascular system in children with myopia

ObjectiveThe objective of the study was to use optical coherence tomography angiography (OCTA) to analyze the effects of repeated low-level red-light (LLLT) therapy on macular retinal thickness and the microvascular system in children with myopia to evaluate the safety of this therapy. MethodsThis prospective study included 40 school-age children with myopia (80 eyes), aged 7–14 years, who received therapy using a LLLT instrument. At baseline and therapy for 1 month, 3 months, 6 months, all children underwent comprehensive ophthalmological examinations, including slit-lamp examination, uncorrected visual acuity, best-corrected visual acuity, spherical equivalent degree, axial length, and OCTA. The vessel densities of the superficial retinal capillary plexus, macular inner retinal thickness, and full-layer retinal thickness were measured. ResultsThe macular inner retinal thickness increased at 1 month and remained unchanged thereafter, It differed significantly in nine areas at 1, 3, and 6 months compared to the thicknesses before therapy (P < 0.05); however, we observed no significant differences between the different time points (P > 0.05). The macular full-layer retinal thickness increased at 1 month and remained unchanged thereafter; the changes showed significant differences at 1 month and 3 months compared to before therapy, for the inner nasal region (P < 0.05). The other eight areas showed significant differences at 1, 3, and 6 months compared with before therapy (P < 0.05); however, no significant difference was observed between the different time points after therapy (P > 0.05). The vessel density of the superficial retinal capillary plexus did not differ significantly among the four groups (P > 0.05). ConclusionsLLLT therapy was safe. The school-aged children exhibited macular thickening after LLLT therapy, which had no significant effect on macular microcirculation.

Religious Reasons and Liberal Legitimacy

Abstract This article addresses the exclusivism–inclusivism debate about religious reasons in law within a justificatory liberal framework. The question of whether religious reasons have justificatory capacity for attaining public justification has increasingly been seen as a matter of how public justification is understood between two rival models: the consensus model being aligned with exclusivism, the convergence model with inclusivism. More recently, however, that alignment has been challenged with attempts to show that consensus can reach an equivalent degree of inclusivism as convergence. Against this, I contend that the purported equivalence is misplaced. First, I identify a crucial ambiguity about public justification and two corresponding domains. Upon demonstrating these to be mutually independent and severable, I conclude that the moves to equalize the models are confined within the more narrow domain while, in the more fundamental domain, the choice of model continues to prove determinative as to the exclusivist or inclusivist valence of justificatory liberalism.

CCM.G-K2.2023: CIPM key comparison of absolute gravimeters

Main textThe Key Comparison of Absolute Gravimeters, CCM.G-K2.2023, was conducted at the Table Mountain Geophysical Observatory (TMGO) near Boulder, Colorado between 21 August and 29 September, 2023. Dr. David Newell of the National Institute of Standards and Technology (NIST), Gaithersburg, Maryland, served as the Pilot Laboratory representative, while Dr. Derek van Westrum of the National Oceanic and Atmospheric Administration National Geodetic Survey (NOAA-NGS), Boulder, Colorado, served as the site host and coordinator. The comparison was organized in accordance with the International Committee for Weights and Measures (CIPM) document CIPM MRA-G-11 of the Consultative Committee for Mass and Related Quantities (CCM) and is registered with the CIPM as CCM.G-K2.2023. Fifteen National Metrology Institutes (NMIs) or Designated Institutes (DIs) participated, with a total of 30 absolute gravimeters from 27 institutes, including 2 atom gravimeters. Since all the contributions of absolute gravity data were consistent within the 95% confidence level of applied consistency tests, no data were omitted in the final analysis. The standard deviation of the gravimeters' degrees of equivalence (DoEs) for CCM.G-K2.2023 is less than 1.3 µGal, indicating excellent agreement among the gravimeters.In this report, the gal (symbol: Gal) is a non-SI unit of acceleration employed in geodesy and geophysics to express acceleration due to gravity, where 1 Gal = 1 cm s-2 (1 µGal = 10-8 m s-2).To reach the main text of this paper, click on Final Report.
