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.

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.

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.

Gross morphological and ultrasonographic dimensions of normal feline kidney with reference to resistive index

Ultrasonography with color Doppler is the most quantitative analysis method for intra-renal parameters. There is a wide variation between authors in the measurement site and referencing the inter-lobar resistivity index (RI) in felines. Our objective is to morphometrically and ultrasonographically investigate the normal renal dimensions and vasculatures and draw up a normal reference value for the renal inter-lobar artery resistivity index (RI) using a Pulsed wave-Doppler ultrasonography. A total of twelve adult domestic cats were sedated and treated according to IACUC regulation guidelines to be examined using Doppler ultrasound. The same cats were used for morphometric investigation and divided into three groups regarding the used technique. The size difference between the right and left kidneys is slight, measuring 17 g (weight), 3.65 ± 0.06 cm (length), 2.54 ± 0.08 cm (width), and 2.21 ± 0.03 cm (thickness) for the right kidney, and about 15 g, 3.42 ± 0.06 cm, 2.32 ± 0.05 cm, and 2.13 ± 0.03 cm for the left one, respectively. There are three patterns of renal arteries’ point of origin. The mean RI values of both kidneys were 0.57 ± 0.08 (0.50–0.67) in the right kidney and 0.60 ± 0.08 (0.51–0.69) in the left kidney. The gross examination and ultrasonography measurements did not have a statistically different effect on the actual renal dimensions. Moreover, 0.69 is considered the standard resistivity index (RI) threshold of the feline inter-lobar artery with no correlation to the animal’s body weight.

A Case Study of a Chinese English Language Learner: Effective English Language Learning Through Interaction

Abstract: This article examines the English learning process of Mei, a 20-year-old Chinese university student, using both quantitative and qualitative analysis methods. Qualitatively, semi-structured interviews and natural observations explored Mei's learning experiences and social language use. Quantitatively, her English proficiency was assessed through CEFR-standard language assessment tests. The study found that: 1) Mei demonstrated high cultural and linguistic sensitivity in social English, effectively using slang and humor; 2) While her vocabulary and syntax skills were sufficient for daily and academic conversations, her vocabulary depth was lacking in complex contexts, potentially due to native language interference. These findings have significant implications for second language acquisition teaching, highlighting the importance of cultural knowledge and suggesting personalized teaching methods to enhance learners' language communication and cultural understanding.

The British Digital Press Archive as a source on the history of the collective memory of the First World War participants in the interwar period

Importance. The 110th anniversary of the First World War outbreak awakens in the public and scientific community not only discussions about the causes of the conflict, but also forces us to turn to the legacy of this process. In this regard, the work actualizes the theme of historical memory of the “Great War”. The purpose of the study is to reflect the complex of the legacy of the First World War in Great Britain in the 1930s by referring to the British Newspaper Archive.Materials and Methods. For the analysis of historical memory in the Great Britain, memoirs, monumental art, works of cinema, music, and many others are often involved. Methods of working with the British newspaper Archive are considered and, based on a specific historical method, we will reflect the perception of the First World War in British society and the situation of veterans in the 1930s. The method of quantitative content analysis is used. The necessary database of source material is selected by keywords, then the selected sources are grouped according to a certain topic. Memoirs, monumental art, works of cinema, music and much more are often used to analyze historical memory in Great Britain. In this work, we will look at the techniques of working with the British Newspaper Archive and, based on a specific historical method, reflect the perception of the First World War in British society and the situation of veterans in the 1930s. Due to the free access to a huge mass of English-language sources, this digital archive is of interest to researchers. The work uses the method of quantitative content analysis.Results and Discussion. During the study of press materials, it can be stated that the following agenda has been identified in the historical memory and legacy of the First World War in Great Britain in the 1930s: 1) the presence of narratives reflecting the pride of British society for the heroism of soldiers and sorrow for the many sacrifices they made in the name of victory in the war; 2) despite the discussions’ existence about the frontline brotherhood during the war period, after the war, veterans rallied into unions and organizations engaged in a wide variety of support (from mediation when applying for a job to appeals to the authorities about pension provision).Conclusion. Thus, despite the apparent immensity of the digital database of the British Newspaper Archive, the application of the well-known methodological principle of “Occam’s razor” makes it possible to compile a corpus of sources that meet the purpose of the study. Immersion in the press materials themselves allows the researcher to immerse himself more in the socio-cultural context of Great Britain in the 1930s. Due to the complexity of the information from the studied sources.

RE-AIM evaluation of accreditation process in Turkey

BackgroundEffects of accreditation on various areas of medical education were studied in literature. However, data about comprehensive evaluation of accreditation activities is limited. This paper aims to present how an accreditation agency self-evaluates its own accreditation activities.MethodsAssociation for Evaluation and Accreditation of Medical Education Programs (TEPDAD) is an accreditation agency in Turkey. RE-AIM evaluation framework was used to evaluate TEPDAD’s activities. The accreditation processes were evaluated through indicators set for each of five RE-AIM evaluation framework dimensions (reach, effectiveness, adoption, implementation and maintenance). Data for evaluation for each dimension were gathered from the documents available in TEPDAD website and archives. Qualitative and quantitative analysis methods were used when necessary to investigate the degree of achievement for each indicator.ResultsSeventy-five (83%) of 90 medical schools meeting the application criteria are registered in the accreditation system. Effectiveness analyses revealed that medical education programs improved in eight areas (education program, student representation, documentation, assessment, infrastructure/facilities, faculty development, educational management). Accreditation processes were well adopted by medical schools and TEPDAD volunteers. The number of medical education programs registered in the accreditation system has gradually increased over years. For the accreditation implementation process, medical schools and TEPDAD evaluators provided positive feedback. Medical schools and TEPDAD invested efforts to maintain the accreditation process over time and changing conditions. All of the previously accredited schools have applied for reaccreditation for the second or third cycles to maintain their status. TEPDAD has maintained its recognition status by national and international authorities by several times. The accreditation standards have been continuously reviewed and renewed when necessary. The organizational structure of TEPDAD has been changed in time considering feedback and past experiences. TEPDAD also arranges meetings to promote and maintain its activities.ConclusionsTEPDAD has achieved significant success in terms of reaching majority of the Turkish medical schools, leading to prominent developments in medical education programs without any significant problems related to process, procedures and maintenance. There are still areas of improvement for TEPDAD such as reaching all targeted schools and guiding medical schools to improve quality in diverse elements of medical education programs.

Market concentration of the Brazilian hospital medical supplementary health system

BackgroundThe Brazilian supplementary health market has undergone transformations in recent years due to constant mergers and acquisitions of by large corporations, contributing to the increase in market concentration, especially in the poorest and least developed regions of the country. Thus, given the care it provides and its economic relevance, understanding the fundamentals of these movements, the likely consequences and trends for the health market are relevant, important, and strategic.ObjectiveTo understand the general and specific context of Brazilian supplementary health, its scenarios, and trends, with emphasis on the analysis of market concentration and recent mergers and acquisitions.MethodologyThe research is applied, descriptive and exploratory and uses secondary data from various sources, submitted to quantitative data analysis methods. The data are organized into three groups: historical and regulatory documents; industry data; and market.ResultsThe results show the growing concentration of the market promoted by large publicly traded corporations, the growing relevance of tech startups on the healthcare landscape, the predominant use of the relative valuation model, with implicit multiples for asset pricing and the prevalence of corporate health plans.ConclusionThe growing concentration of the system projects a market with fewer options and less competitiveness, since the growth of large operators is evident, in addition to the relevant increase in the number of complaints from users of the system, which signals the growing gap between the expectations of users and the levels of quality care offered. The study also highlights the predominance of corporate health plans, revealing the direct relationship between access to supplementary health services and employability rates. The analysis of M&A operations, in addition to the increase in market concentration, reveals the prevalence of the use of the relative valuation model and implicit multiples for the pricing of traded assets. This denotes the future expectation of wealth generation, at least equivalent to the historical series of the sector, on the part of investors, whose frustration may signal the decreasing attractiveness of resources and M&A operations in the sector in the coming years.

Exploring Digital Mobility in China’s Tourism Metaverse

The research model was constructed through influential factors to determine the digital mobility of metaverse systems using quantitative data analysis methods. Results showed that information entropy negatively influenced digital mobility. However, media functionality could be harnessed to reduce information entropy and thus enhance digital mobility in China’s tourism metaverse systems. Structural differentiation had significant moderation and mediation effects in the research model that influenced the digital mobility of Chinese tourists.

Navigating legitimacy: diverse stakeholder perspectives on the IFRS foundation’s establishment of the ISSB

Purpose In 2020, the IFRS Foundation’s public consultation on Sustainability Reporting provided an opportunity for stakeholders to share their opinions on the Foundation’s proposals. This paper aims to analyze the comment letters that would legitimize the IFRS Foundation to institutionalize the International Sustainability Standards Board (ISSB). Design/methodology/approach This study used Python to develop a model for analyzing all 577 submissions that the IFRS Foundation received, using a combination of quantitative and qualitative content analysis methods. Findings Support for the creation of the ISSB was not unanimous but reached 68%. Key supporting arguments were that the IFRS Foundation could harmonize sustainability reporting standards by leveraging its expertise in setting accounting standards, and use its existing relationships to enforce sustainability reporting. Key counterarguments were: the IFRS Foundation lacks expertise in the areas of sustainability and climate; sustainability reporting should be integrated into financial reporting rather than being disclosed separately; the proposals were limited in scope (single materiality, focus on investors’ information needs and climate change centrism); and the IFRS Foundation should aim to endorse already established frameworks instead. Practical implications A consensus between supporters and critics was the need to make sustainability reporting mandatory. Endorsed by IOSCO, the ISSB released its inaugural standards, focusing on climate-related disclosures, effective from 2024 in jurisdictions that choose to adopt them. Originality/value The findings show that the establishment of the ISSB by the IFRS Foundation only partially fulfilled the demand for the harmonization of sustainability reporting standards. As a result, broader and non-investor-centric sustainability information may continue to be reported under alternative frameworks.
