Evaluating the social return on investment of dance movement for wellbeing in the prevention of burnout among healthcare staff: a study protocol.

Improvement in the National Health Service (NHS) employees' mental well-being and staff retention are current key issues. Evidence indicates that dance movement therapy (DMT) has been effective in improving mental health and well-being; however, a social return on investment (SROI) evaluation on DMT interventions aimed at NHS staff has not been performed. This protocol for an SROI study will explore the social value generated from DMT, specifically 'The Body Moving Self-Compassion' programme, as measured by the increase in personal well-being and resilience experienced by participants. The SROI evaluation aims to measure the monetary and social value generated through DMT by placing a monetary value which is essential for sound policy in accessing investment while contributing evidence of dance/movement's impact on health. SROI is a pragmatic form of social cost-benefit analysis which uses quantitative and qualitative methods to value relevant costs, outcomes and associated impact. A mixed-methods approach design (focus group, online questionnaire and semistructured interviews) will be employed in this SROI study. SROI takes a societal perspective and considers relevant and significant outcomes for participants. Monetary values which often do not have a market price are then assigned to these outcomes. Contingent valuation is integrated into this study to estimate individuals' choices, preferences and values associated with DMT. The social value generated by the identified outcomes will then be estimated in a similar way to cost-benefit analysis, and the ratio of social value generated per £1 invested is then calculated. Ethical approval for this study has been granted by the Faculty of Life Sciences and Education Ethics Subgroup at the University of South Wales, with Reference No. 230 236LR. The findings from this SROI study will result in a report and academic publications.

Causal and common risk pathways linking childhood maltreatment to later intimate partner violence victimization.

Childhood maltreatment and intimate partner violence (IPV) victimization are major psychiatric risk factors. Maltreatment substantially increases the likelihood of subsequent IPV victimization, but what drives this association is poorly understood. We analyzed retrospective self-reports of maltreatment and IPV victimization in 12,794 participants (58% women, 42% men) from the Twins Early Development Study at ages 21 and 26 using quantitative genetic methods. We estimated the etiological influences common to maltreatment and IPV, and the effect of maltreatment on IPV beyond such common influences. Participants who reported childhood maltreatment ( ~ 7% of the sample) were 3 times more likely than their peers to also report IPV victimization at age 21, 4 times more likely at 26. The association between maltreatment and IPV was mostly due to environmental influences shared by co-twins (42-43%) and genetic influences (30-33%), as well as nonshared environmental influences (25-27%). The association between maltreatment and IPV was similar for women and men, but its etiology partly differed by sex. Maltreatment had a moderate effect on IPV in phenotypic models (β = 0.25-0.30), decreasing to a small-to-moderate range in causally informative models accounting for their common etiology (β = 0.15-0.21). Risk factors common to maltreatment and IPV victimization are largely familial in origin, environmental and genetic. Even considering common risk factors, experiencing maltreatment may be causally related to subsequent IPV victimization. Interventions promoting safe intimate relationships among young adults exposed to maltreatment are warranted and should address family-level environmental risk and individual-level risk shaped by genetics.

Teachers’ Perspectives on AI-Driven Quillionz for Generating EFL Reading Comprehension Quizzes

Emerging artificial intelligence (AI) has significant impacts on language learning and teaching, providing innovative pedagogies in sustainable educational settings. Among the powerful tools stands Quillionz (https://www.quillionz.com), a free AI-powered platform for building questions, quizzes, and assessments. Nevertheless, there has been little research on teachers’ experiences and perceptions of using Quillionz in EFL classroom settings. This study set out to explore teachers’ perspectives on utilizing Quillionz to generate reading comprehension quizzes for non-English major students through a pre and post-survey design. The research employed both qualitative and quantitative methods with Likert-scale questionnaires distributed to 48 English teachers from a vocational college in Hanoi before and after using Quillionz over four weeks. A paired sample T-Test was conducted to explore shifts in teachers’ perceptions. Subsequently, in-depth interviews were carried out with 10 randomly selected participants for further investigation. The findings revealed positive views among teachers towards Quillionz, its identified potential, and suggestions for more effective implementation. This paper makes a significant contribution to the integration of technology in language teaching, thereby enhancing students’ learning experiences.

Bridging the gap: enhancing orthopaedic outcomes through qualitative research integration.

The evidence base within trauma and orthopaedics has traditionally favoured quantitative research methodologies. Qualitative research can provide unique insights which illuminate patient experiences and perceptions of care. Qualitative methods reveal the subjective narratives of patients that are not captured by quantitative data, providing a more comprehensive understanding of patient-centred care. The aim of this study is to quantify the level of qualitative research within the orthopaedic literature. A bibliometric search of journals' online archives and multiple databases was undertaken in March 2024, to identify articles using qualitative research methods in the top 12 trauma and orthopaedic journals based on the 2023 impact factor and SCImago rating. The bibliometric search was conducted and reported in accordance with the preliminary guideline for reporting bibliometric reviews of the biomedical literature (BIBLIO). Of the 7,201 papers reviewed, 136 included qualitative methods (0.1%). There was no significant difference between the journals, apart from Bone & Joint Open, which included 21 studies using qualitative methods, equalling 4% of its published articles. This study demonstrates that there is a very low number of qualitative research papers published within trauma and orthopaedic journals. Given the increasing focus on patient outcomes and improving the patient experience, it may be argued that there is a requirement to support both quantitative and qualitative approaches to orthopaedic research. Combining qualitative and quantitative methods may effectively address the complex and personal aspects of patients' care, ensuring that outcomes align with patient values and enhance overall care quality.

Quantifying pigment features of Thangka Five Buddhas using hyperspectral imaging

Thangka, a masterpiece of Tibetan painting, is renowned for its adept use of natural mineral pigments such as gold, turquoise, and cinnabar, which imbue it with profound artistic and historical significance. Presently, chemical analysis methods relying on microscopic perspectives are prevalent in researching the pigment components of cultural artifacts. However, these methods suffer from quantization gaps and carry the risk of damaging the relics. Hence, in this study, we focus on Thangka Five Buddha as our experimental sample and propose a novel approach utilizing Linear Spectral Mixed Analysis (LSMA) based on Hyperspectral Imaging (HSI) technology to perform quantitative analysis of pigment components at a sub-pixel level. The results indicate the following. 1) A database of spectral curves for 25 representative Thangka pigments was established, covering 196 bands from 393 to 800 nm VIR-NIR range. 2) The LSMA model successfully separated the 13 pigment components of the Thangka at the sub-pixel level, achieving a Root Mean Square Error (RMSE) of 0.0186, which indicates high classification accuracy. 3) The quantitative analysis reveals that 33.07 % of the area is painted using a single pigment, while 56.01 % is painted using a combination of two pigments. Verdigris (18.56 %), malachite (17.52 %), and cinnabar (10.91 %) are the pigment types with the highest proportions among them. Out of the 521 pigment combinations, verdigris and turquoise (4.55 %), malachite and calcite (4.02 %), minium and cinnabar (2.87 %), and turquoise and malachite (2.82 %) are more commonly used. 4) The application of quantitative analysis methods demonstrates significant potential in painting techniques, authentication processes, and establishing historical dating, among other areas of study.

Education has undergone a fundamental change driven by technological advances, significantly altering the way teaching and learning is conceptualized in the classroom. Currently the variety of learning and teaching platforms is extensive and in general, these have been very well received by language teachers. The use of these platforms is often driven by teachers’ eagerness to keep students motivated, engaged, and focused throughout a class. This exploratory study investigates engineering undergraduates’ perceptions of integrating Kahoot! (a Game-based Student Response System (GSRS)) to review technological vocabulary and grammar before their unit tests. Students’ perceptions were assessed using quantitative and qualitative methods throughout one semester. The findings indicated that students found the use of Kahoot! to be beneficial in relation to: (1) improving technological vocabulary in English (2) review more complex grammatical structures; (3) enjoy a more relaxed classroom environment. Finally, the present article presents some implications that may be useful to language lecturers.

Negative and Positive Experiences During the COVID-19 Pandemic in Canadians With Developmental Disabilities: AOne-Year Ontario-Based Survey.

Understanding the experiences of people with developmental disabilities during the initial period of COVID-19 pandemic. Individuals with developmental disabilities and their caregivers completed baseline and up to five follow-up online surveys using the CRISIS-AFAR measures, between July 2020 and September 2021. We used qualitative (thematic analysis) and quantitative (MANOVA) analytic methods. One hundred and eighteen participants (64 caregivers on individuals 6-62 years, 54 self-reporting individuals aged 17-55 years) completed baseline survey; 46 participants (23 caregivers, 23 self-reporting adults) completed ≥1 follow-up. Qualitative themes included uncertainty, and negative and positive influences on behaviours and routines, daily life and mental wellness. Those experiencing positive impacts did not stably perceive so longitudinally. Despite both negative and positive influences on individuals with developmental disabilities and their families, the prolonged pandemic had wide-ranging repercussions. Emergency preparedness planning should consider the disruptive effects of public health measures on routine and support for this vulnerable population.

Rockery morphology based on quantitative analysis of shading

The rockeries of classical Chinese gardens are masterpieces of classical Chinese garden art and form a key element of garden heritage. Consequently, a quantitative study of “rockery shadows” is of considerable importance to the study of “rockery forms.” In this study, we selected the representative North Rockery in Zhanyuan Garden of Nanjing and Ruiyunfeng, Guanyunfeng, and Yulinglong as the objects of the study. This study aims to explore the shadow images of rockeries using image extraction and targeted quantitative analysis methods. Macroscopically, the overall shape of rockery shadows was described using fractal dimensions; microscopically, the aspect ratio, angle, and refinement indexes of each shadow based on each observation angle of the rockery were measured using the PAT-GEOM plug-in in ImageJ software. SPSS Statistics was used for the normal distribution test of the angular distribution data. Consequently, the shadow data of the North Rockery in Zhanyuan Garden and Ruiyunfeng, Guanyunfeng, and Yulinglong, respectively, were analyzed and compared, and four rockery-shadow laws were derived. Finally, the results were applied to the design of the rockery morphological translation based on quantitative analysis of the shadows. The approach presented here will enhance landscape design, support environmental planning, and preserve cultural heritage.

MASLD: What We Have Learned and Where We Need to Go-A Call to Action.

Since its introduction in 1980, fatty liver disease (now termed metabolic dysfunction-associated steatotic liver disease [MASLD]) has grown in prevalence significantly, paralleling the rise of obesity worldwide. While MASLD has been the subject of extensive research leading to significant progress in the understanding of its pathophysiology and progression factors, several gaps in knowledge remain. In this pictorial review, the authors present the latest insights into MASLD, covering its recent nomenclature change, spectrum of disease, epidemiology, morbidity, and mortality. The authors also discuss current qualitative and quantitative imaging methods for assessing and monitoring MASLD. Last, they propose six unsolved challenges in MASLD assessment, which they term the proliferation, reproducibility, reporting, needle-in-the-haystack, availability, and knowledge problems. These challenges offer opportunities for the radiology community to proactively contribute to their resolution. The authors conclude with a call to action for the entire radiology community to claim a seat at the table, collaborate with other societies, and commit to advancing the development, validation, dissemination, and accessibility of the imaging technologies required to combat the looming health care crisis of MASLD.

Post mortem chiral analysis of MDMA and MDA in human blood and hair

Drug-related fatalities in the EU are predominantly associated with opioids. MDMA (Ecstasy) consumption results in fewer lethal intoxications despite its widespread use. This study investigates MDMA-related fatalities, focusing on enantiomer ratios of MDMA and its metabolite MDA to explore the role of metabolism in fatal outcomes.MDMA induces euphoria, increased empathy, and physiological effects such as tachycardia, hypertension, and hyperthermia. Metabolism mainly involves CYP1A2 and CYP2D6, with polymorphism of the latter influencing metabolism rates. Our institute observed several MDMA-related fatalities, which prompted an investigation into the potential role of inefficient drug metabolism in these cases.A novel quantitative chiral analysis method was developed and validated for MDMA, MDA, amphetamine and methamphetamine enantiomers in human blood. Analysis of post mortem blood samples from eleven MDMA-related fatalities exhibited a wide range of concentrations and enantiomer ratios. Variability in R/S MDMA ratios, however, could be linked to the time period of metabolism. Hair analysis revealed high MDMA concentrations in all segments, irrespective of prior drug abuse anamnesis. Therefore, hair analysis may not be suitable for the assessment of past drug use in ecstasy-related fatalities.The results indicated that elevated levels of the MDMA enantiomer are correlated with longer survival times in cases of intoxication. However, there was no clear evidence for slowed MDMA metabolism as a cause of lethal intoxications. While challenges remain due to the diversity of cases, this study contributes valuable insights into ecstasy intoxications, aiding future interpretation of post mortem analysis.

The analysis of a causal model of learning organization on sustainable organizational performance of public IT companies in China: Knowledge management practices and innovation capability as multiple mediators

This research aims to empirically examine the role of learning organization practices in enhancing sustainable organizational performance, utilizing knowledge management and innovation capability as mediating variables. The study was conducted in public IT companies across China, which is a vital sector for driving innovation and economic growth. A mixed-methods approach was employed, with quantitative methods accounting for 70% and qualitative methods for 30% of the research. Purposive sampling was utilized to distribute questionnaires to 546 employees from 10 public IT companies. Statistical analysis was conducted using Structural Equation Modeling (SEM). The findings indicate that learning organization practices significantly influence knowledge management practices (β = 0.785, p < 0.001) and innovation capability (β = 0.405, p < 0.001). Furthermore, knowledge management practices positively contribute to sustainable organizational performance (β = 0.541, p < 0.001), while innovation capability also has a positive effect (β = 0.143, p < 0.001). Moreover, knowledge management practices partially mediate the relationship between learning organization practices and sustainable performance, with a total effect of 0.788 (p < 0.001). The mediating role of innovation capability is also significant, with a total effect of 0.422 (p = 0.045). The study further includes qualitative in-depth interviews with 20 managers from 10 IT companies across five regions in China: East, South, West, North, and Central. Senior managers were selected through a stratified sampling method to ensure comprehensive representation by including both the largest and smallest companies in each region. These findings underscore the critical role of learning organizations in promoting sustainability through effective knowledge management and innovation capabilities within the IT sector.

Gambaran Pengasuhan Orang Tua di Suku Nias

Parents are the primary and first educators of children within a family. In the process of emotional adjustment for children, this cannot be separated from family support. Communication is the key to relationships within a family. The parenting style of the Nias ethnic group has its own uniqueness influenced by local culture and values. According to Vinden (2001), there are two parenting styles: authoritarian and authoritative. This study aims to describe the parenting practices of the Nias ethnic group. The research employs a quantitative method using descriptive statistical analysis. The population for this study consists of parents in the Nias ethnic group, with a total of 60 subjects. The sampling technique used is purposive sampling. This study utilizes the parenting style scale developed by Vinden, which has been modified by O'Reily and Peterson (2014) and adapted into Indonesian by Hasanah and Rusli (2020). Based on the research results, the mean for authoritarian parenting style is 18.9 with a standard deviation of 1.50, while the mean for authoritative parenting style is 10.3 with a standard deviation of 1.84. This indicates that the authoritarian parenting style among parents in the Nias ethnic group is higher.

CritSEM: Advancing QuantCrit to Examine Racialized Resegregation in Special Education

The field of education urgently needs research, aligned with QuantCrit, to disrupt the racialized overrepresentation [resegregation] of Black and Latinx students in special education. Our concern about how statistics have been (mis)applied motivated us to consider the possibility of quantitative methods for use in educational research that aims to dismantle white supremacy. Therefore, we developed CritSEM (Critical Structural Equation Modeling) as a methodological intervention for the purpose of telling a Critical Race Counterstory. Specifically, we examined the extent that anti-racist educators can disrupt processes causing the resegregation of Black and Latinx students in special education, using restricted data from the 2011 Early Childhood Longitudinal Study. Our study concludes with a discussion and implications about working toward an anti-racist special education system and applying QuantCrit in advanced statistical methods.

High-throughput identification of calcium-regulated proteins across diverse proteomes

Calcium ions play important roles in nearly every biological process, yet whole-proteome analysis of calcium effectors has been hindered by a lack of high-throughput, unbiased, and quantitative methods to identify protein-calcium engagement. To address this, we adapted protein thermostability assays in budding yeast, human cells, and mouse mitochondria. Based on calcium-dependent thermostability, we identified 2,884 putative calcium-regulated proteins across human, mouse, and yeast proteomes. These data revealed calcium engagement of signaling hubs and cellular processes, including metabolic enzymes and the spliceosome. Cross-species comparison of calcium-protein engagement and mutagenesis experiments identified residue-specific cation engagement, even within well-known EF-hand domains. Additionally, we found that the dienoyl-coenzyme A (CoA) reductase DECR1 binds calcium at physiologically relevant concentrations with substrate-specific affinity, suggesting direct calcium regulation of mitochondrial fatty acid oxidation. These discovery-based proteomic analyses of calcium effectors establish a key resource to dissect cation engagement and its mechanistic effects across multiple species and diverse biological processes.
