The Profiles of Health Aging in Older Ethiopian Adults within the WHO Healthy Aging Framework

AbstractThe World Health Organisation’s (WHO) Healthy Aging framework describes healthy aging as the maintenance of functional capacity in older adults. However, aging is a heterogeneous process influenced by genetics, lifestyle, and environmental factors, leading to variations in experiences of functional capacity among adults. In this study, Latent Class Analysis (LCA) classified groups of individuals based on their health and functional capacities. Adults from Northwest Ethiopia (n = 845) aged ≥ 60 years old, were interviewed about their cognition, mental health, social support, independence, and sensory functioning. LCA identified three groups, reflecting “high-“ (47.5%); "moderate-" (37.3%); and "low-functioning" (15.2%) participants. Compared to low-functioning individuals, high-functioning individuals were less likely to be aged 80+ (RR = 0.61; 95% CI: 0.46, 0.80), lonely (RR = 2.34; 95% CI: 1.72, 3.18), but more likely to report normal nutritional status (RR = 2.05; 95% CI: 1.47, 2.86), no multimorbidity (RR = 1.18; 95% CI: 1.06, 1.32), living in an urban area (RR = 1.12; 95% CI: 1.03, 1.22), and financially independent (RR = 1.24; 95% CI: 1.03, 1.49). Notably, almost half of the sample was classified as high functioning, comparable to findings from other developing countries. Those individuals in the high-functioning group who did not meet the WHO criteria for functional capacity across all domains did not differ from those individuals who did meet all the WHO criteria. This positively demonstrates that older adults do not need to be functional across all dimensions to experience healthy aging.

Integration and Evaluation of a Digital Support Function for Space Claims in Factory Layout Planning

Planning and designing factory layouts are frequently performed within virtual environments, relying on inputs from various cross-disciplinary activities e.g., product development, manufacturing process planning, resource descriptions, ergonomics, and safety. The success of this process heavily relies on the expertise of the practitioners performing the task. Studies have shown that layout planning often hinges on the practitioners’ knowledge and interpretation of current rules and requirements. As there is significant variability in this knowledge and interpretation, there is a risk that decisions are made on incorrect grounds. Consequently, the layout planning process depends on individual proficiency. In alignment with Industry 4.0 and Industry 5.0 principles, there is a growing emphasis on providing practitioners involved in industrial development processes with efficient decision support tools. This paper presents a digital support function integrated into a virtual layout planning tool, developed to support practitioners in considering current rules and requirements for space claims in the layout planning process. This digital support function was evaluated by industry practitioners and stakeholders involved in the factory layout planning process. This initiative forms part of a broader strategy to provide advanced digital support to layout planners, enhancing objectivity and efficiency in the layout planning process while bridging cross-disciplinary gaps.

Family Resilience in Patients With Schizophrenia: Potential Influencing Factors and Mediating Effect.

To identify the determinants of family resilience in the recovery of individuals with schizophrenia using Walsh's family resilience framework. A cross-sectional study. In Northeast China, 403 patients diagnosed with schizophrenia were enrolled for this study, assessing family resilience, family communication, social support, illness knowledge, hope and family functioning. Regression analyses were conducted using SPSS 27.0, and mediation effects were examined using Mplus 7.0. Logistic regression showed that female gender and having a sibling as a caregiver were negatively associated with family resilience, while a higher educational level was positively associated. Mediation analysis showed that family functioning and hope levels mediated the impact of family communication, social support and disease knowledge on family resilience, confirming their crucial roles. Family functioning and hope are central in mediating the relationships between family communication, social support, illness knowledge and family resilience in families dealing with schizophrenia. The findings of this study enable psychiatric nurses and policymakers to devise intervention strategies that enhance family resilience among patients with schizophrenia, thereby facilitating their recovery and well-being. No patient or public engagement.

Ru nanoparticles on mesostructured carbon for glucose hydrogenation; catalysts synthesis and characterization

Ru-containing hydrogenation catalysts based on functionalized carbon material CMK-3 (Carbon Mesostructured by KAIST) were developed. Mesostructured silicate SBA-15 with enlarged wall channels was used as a template for the carbon replica synthesis. The effect of carbon material functionalization via moist air oxidation and sulfonation on the morphology, physicochemical properties and activity of the catalyst was studied. The dispersion, localization, and electronic state of supported ruthenium were determined depending on the support functionalization method. The initial support structure preservation after Ru deposition was confirmed by a set of physicochemical methods. Metal particles are finely distributed with no agglomerated present, providing a high active site accessibility and ensures a superb catalyst activity. The catalysts were tested in glucose to sorbitol hydrogenation. The results showed that pore morphology and carbon support initial structure preservation account for the catalytic activity of Ru nanoparticles.

Exploring the Role of Social Support and Sexual Functioning: A Study of Chemsex and Sober Sex in Men Who Have Sex with Men

ABSTRACT Research on chemsex, the intentional use of certain drugs in sexual contexts by gay men and other men who have sex with men (MSM), has been growing in recent years although, even today, much of it focuses on drug use and its consequences, rather than on the sexual and social experiences of users. This study aimed to explore the influence of social support and sexual functioning on the frequency of chemsex and sober sex. A sample of 160 MSM WAS recruited through social media and NGOs. Through regression analysis, it was found that lower perceived social support and greater number of routes of drug administration predicted a higher frequency of chemsex practice. On the other hand, higher perceived social support, higher levels of desire and arousal, and fewer routes of drug administration predicted a higher frequency of engaging in sober sex. This study provides empirical evidence that both social support and sexual functioning are key elements in chemsex and have an impact on both the frequency of chemsex and sober sex. Given the importance of these elements, we suggest that interventions should be framed holistically. Nevertheless, not all chemsex is problematic and it is a free choice in sexuality.

Physiotherapy in the digital age: A narrative review of the paradigm shift driven by the integration of artificial intelligence and machine learning

Abstract: A variety of physical impairments and functional restrictions are assessed and treated in the practice of physiotherapy. Subjective measures, rater variability, and restricted access to high-quality care are some of the unavoidable problems that contemporary physical therapy practice approaches must overcome. In light of these challenges, cutting-edge technologies such as artificial intelligence (AI) and machine learning (ML) are demonstrating remarkable efficacy in tackling these issues head-on. The focus of this review is to explore how the integration of AI and ML might change physical therapy practice and education in the age of digital communication. It delves into the challenges accompanying this integration and considers future prospects in this domain. A literature search was conducted using data base PubMed, Google Scholar, Web of Science, and Scopus with keywords such as ‘physiotherapy’, ‘artificial intelligence’, and ‘machine learning’, limited to English articles from 2014 to 2024. Results were imported into reference management software, duplicates removed, and relevant articles were screened and assessed for inclusion, with reasons for exclusion documented. Emerging technologies like AI and ML use algorithms to examine patient data and make automatic decisions, enhancing areas such as virtual reality therapy (VR), tele-rehabilitation, clinical decision support, individualized rehabilitation and physical function evaluation. These advance technologies optimize physical therapy and improve outcomes, but further research is needed to address obstacles like bias and data privacy to ensure responsible implementation. AI and ML can revolutionize physical therapy by improving therapy precision, patient monitoring, optimization and individualized therapy plan. However, it’s crucial for physiotherapists to balance technological advancements with compassionate, patient-centred approach.

Sources of perceived social support and cognitive function among older adults: a longitudinal study in rural China.

Studies have shown the positive impact of perceived social support on cognitive function among older adults in rural areas. However, existing studies often overlook the impact of different support sources. This study aimed to explore the relationship between the diverse sources of perceived social support and cognitive function. Participants were drawn from the Guizhou Rural Older Adults' Health Study (HSRO) in China. We included 791 participants who participated in a baseline survey in 2019 and a 3-year follow-up survey. Perceived social support was investigated from the six main sources (friend, relative, children, spouse, sibling, and neighbor). Hierarchical linear regression models were used to observe the effects of diverse sources of perceived social support and their combinations on cognitive function. Cognitive function was positively associated with perceived support from children, friends, and neighbors. A positive association was found between cognitive function and increases in each additional source [β = 0.75 (95%CI: 0.51, 0.98), p < 0.001]. Older adults who perceived support from both children and friends showed better cognitive function [β = 2.53 (95%CI: 1.35, 3.72), p < 0.001]. The perception of support from spouse, siblings, and relatives did not show a statistically significant association with cognitive function among older adults in rural areas. This study found that the association between different sources of perceived social support and cognitive function was varied. This study provides scientific evidence that personalized support strategies may benefit in promoting cognitive health in rural older adults.

Examining the Psychosocial Factors of Mental Health Well-being Among Medical University Students: Gender-based Analyses

The mental health of university students is a major concern due to the various stressors they face, including academic pressures, social dynamics, and personal development challenges. Previous studies have shown that gender differences significantly impact how students perceive and express psychological distress. This study aimed to identify these differences in the context of academic stress, social support, self-esteem, academic motivation, and family functioning, and their association with psychological distress. The study involved 2206 medical students in a cross-sectional study at a medical university in Ningxia, western China. The data analysis revealed significant gender differences in scores for academic stress, social support, and academic motivation. Academic stress, social support, and family functioning were found to be significantly associated with psychological distress for both genders. However, academic motivation was found to significantly influence psychological distress only among male students, while self-esteem had an impact on female students. These findings highlight the need for tailored mental health services in universities to address gender-specific needs, such as providing counseling services that focus on coping with academic stress and strengthening social and familial support networks to improve student well-being.

Talking to the young generation: perception of nature-based solutions’ attractiveness by children from Generation Z

ABSTRACT Current studies on nature-based solutions (NBS) in urban areas often overlook young people, who are essential users of urban spaces. Our study from the Czech Republic fills this gap by investigating how children (Generation Z, 11–15 years) perceive 12 NBS and 3 grey infrastructure measures and their ecosystem services (ES). Results from an image-based questionnaire survey indicate that water features, trees and flower beds are the most attractive for spending leisure time, while most other features were perceived as relatively unattractive by the children surveyed. In addition, the results highlight oxygen production as the most valued service by children, followed by biodiversity support and aesthetic function. This study emphasises the need for inclusive management of NBS and recognises the role of multiple stakeholders, including children, in creating attractive urban spaces. Key policy highlights Exploring the preferences of Generation Z towards different nature-based solutions Some measures and benefits were perceived as more attractive and important Water features, trees, and flower beds were rated as the most attractive measures Oxygen provisioning, biodiversity, and aesthetics were identified as the most important benefits Children and young people are essential users of urban nature and public spaces

Stability of the Wulff shape with respect to anisotropic curvature functionals

For a function f which foliates a one-sided neighborhood of a closed hypersurface M, we give an estimate of the distance of M to a Wulff shape in terms of the Lp-norm of the traceless F-Hessian of f, where F is the support function of the Wulff shape. This theorem is applied to prove quantitative stability results for the anisotropic Heintze-Karcher inequality, the anisotropic Alexandrov problem, as well as for the anisotropic overdetermined boundary value problem of Serrin-type.

Sakkyndige psykologers refleksjoner om Barnesakkyndig kommisjons kvalitetssikrende funksjon

The future of many vulnerable children depends on the quality of child welfare decisions, where reports from independent child welfare experts may carry considerable weight. Before these reports are used in child welfare decision-making processes, they are quality-assessed by the Expert Commission on Children. In the present study, 12 psychologists working as independent child welfare experts were interviewed about their experiences of the Expert Commission on Children’s quality assurance function. Based on qualitative thematic analyses, the informants’ statements were sorted into two main themes. The first main theme circled around experiences that the Commission enhances the quality of the experts’ work by having a ‘Sharpening support function’, contributing to a more unified and consistent practice. Under the second main theme, ‘What type of quality?’, concerns were raised that the Commission, due to lack of access to the factual basis of the reports, cannot accurately evaluate their professional or substantial quality. The informants suggested alternative quality assurance methods, such as feedback loops between the Commission and the experts, and that the Commission should instead undertake an in-depth examination of a smaller sample of reports. The findings are discussed in the context of the broader debate surrounding quality indicators for child welfare work. Keywords: independent expert, assessment, child welfare, quality assurance, Commission for child welfare experts

Post mortem Study of Catalyst Degradations Occurring in High-Temperature Proton Exchange Membrane Fuel Cells Upon Start-Stop Operation

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) could replace fossil fuel-based technologies for applications which cannot involve bulky/heavy cooling systems, such as aeronautics. However, severe materials degradations upon operation prevent performance retention for acceptable lifetimes. While others have already reported degradations in HT-PEMFC, post mortem characterizations of used HT-PEMFC membrane electrode assemblies (MEAs) remain scarce. Herein, HT-PEMFC performance degradation is studied by applying a startup/shutdown protocol to a short-stack operated at 160 °C; one MEA is characterized using complementary physicochemical/electrochemical techniques to identify/understand the degradation mechanisms and their origin. This start/stop operation mode (co-flow gas reactants) leads to substantial degradation inhomogeneity. For the anode, migration, coalescence, and detachment of Pt nanoparticles are witnessed induced by high-surface-area carbon support functionalization and corrosion. The anode electrochemical surface area (ECSA) remains constant at the inlet and increases significantly at the outlet, following inhomogeneous degradation of the cathode catalyst: the Ptz+ ions formed at high potential/oxidizing conditions concentrate towards the outlet, where they redeposit locally or at the anode, after diffusion/migration across the PBI membrane. Hence, the cathode ECSA decreases significantly at the inlet. Furthermore, intense Ni-leaching from the initial PtNi alloy catalyst is reported as a result of O2 mass-transport and phosphoric acid dilution inhomogeneity.

Perceived benefits and challenges of using an electronic cancer prediction system for safety netting in primary care: An exploratory study of C the signs.

This paper reports on an exploratory study into the perceived benefits and challenges of using an electronic cancer prediction system, C the Signs, for safety netting within a Primary Care Network (PCN) in the East of England. The study involved semi-structured interviews and a qualitative questionnaire with a sample of 15 clinicians and practice administrators within four GP practices in the PCN. Participants generally perceived benefits of C the Signs for managing and monitoring referrals as part of post-consultation safety netting. Clinicians made little use of the decision support function though, as part of safety netting during the consultation, and referrals were still sent by administrators, rather than directly by clinicians through C the Signs. Emphasising the benefits of C the Signs for post-consultation safety netting is most likely to gain buy-in to the system from clinicians, and can also be used by administrators for shared visibility of referrals. More evidence is needed on the value of C the Signs for safety netting during the consultation, through better diagnosis of cancer, before this is seen as a valued benefit by clinicians and provides motivation to use the system.

Social Support, Coping Strategies, Depression, Anxiety, and Cognitive Function Among People With Type 2 Diabetes Mellitus: A Path Analysis.

To explore the linear associations between social support, coping strategies, depression, anxiety, and cognitive function among people with type 2 diabetes mellitus (T2DM) using a path-analytic method. This cross-sectional study enrolled 496 individuals hospitalized due to T2DM. Well-trained investigators conducted face-to-face interviews with the participants using the Social Support Rating Scale, the Chinese version of Medical Coping Modes Questionnaire, the Hospital Anxiety and Depression scale, and the Mini Mental State Examination to measure social support (including objective support, subjective support, and support utilization), coping strategies (including confrontation, avoidance, and acceptance-resignation), depression/anxiety, and cognitive function, respectively. A path analysis was used to elucidate the linear associations between social support, coping strategies, depression, anxiety, and cognitive function. In the final path model with satisfactory model fit, objective support was found to be associated with cognitive function not only directly but also indirectly through confrontation coping and depression, and acceptance-resignation coping and depression/anxiety. Further, subjective support was found to be associated with cognitive function indirectly through depression/anxiety, as well as serially through acceptance-resignation coping and depression/anxiety. Support utilization was found to be associated with cognitive function indirectly through confrontation coping and depression, as well as through acceptance-resignation coping and depression/anxiety. Social support, coping strategies, depression, and anxiety were associated with cognitive function among people with T2DM, and these associations were best explained by a serial mediation model from social support, coping strategies, and depression and anxiety to cognitive function.

Qualitative study on health self-management of patients with metabolic syndrome among bereaved population after earthquake

The study explore the influencing factors and healthy self-management of MS patients with bereaved relatives after Wenchuan and Yushu Earthquake of their real life; explore difficulties and challenges in the process of self-management; and supply information that could not be sought in quantitative studies. Purposive sampling was used to recruit 36 MS patients who are bereavement population in two earthquakes, and those patients met the inclusion criteria for semi-structured focus group interview. The Nvivo11 software was used to collate and analyze the transcribed data. The main influencing factors of health self-management behavior for MS patients are as follows: the degree of understanding of disease prevention knowledge, emotion management induced by earthquake trauma, the source of disease-related information, access and identification are very limited; ethnic traditional culture, religious beliefs, and production activities and routines before and after the earthquake is an important factor in their healthy self-management behavior. The lack of health beliefs and self-efficacy of MS patients among bereaved families after Wenchuan and Yushu earthquake are key obstacle in their self-management. The overall level of the knowledge of patients’ MS prevention, self-efficacy and self-management behaviors are still low. Some positive factors that can be changed including MS prevention knowledge, self-efficacy, social support, and family function. Some negative factors which can be improved afterwards, including negative coping style, traumatic life experiences from earthquake and smoking.

The labor of assetization: producing ‘hypergrowth’ inside a tech startup

Abstract Venture capitalists maximize profits not by ‘squeezing’ efficiencies out of established companies, but instead by promoting ceaseless experimentation aimed at helping startups achieve ‘hypergrowth’. To date, there is limited empirical evidence of both how startups achieve hypergrowth, and the impact of these practices on organizations and workers. This article draws on 19 months of participant-observation research inside a venture-backed startup I call AllDone to trace the links between the institution of venture capital and the organization of work. Although AllDone executives engaged in cost-cutting strategies common to other financialized firms, they also developed distinctive corporate strategies and organizational structures. Each of the company’s three work teams was organized to perform interdependent functions in support of venture capital’s imperative for rapid and exponential asset value inflation. I conclude with a discussion of the article’s implications for research on venture capital, startup work, and the relationship between financialization and work more broadly.

On Spacelike Hypersurfaces in Generalized Robertson–Walker Spacetimes

This paper investigates generalized Robertson–Walker (GRW) spacetimes by analyzing Riemannian hypersurfaces within pseudo-Riemannian warped product manifolds of the form (M¯,g¯), where M¯=R×fM and g¯=ϵdt2+f2(t)gM. We focus on the scalar curvature of these hypersurfaces, establishing upper and lower bounds, particularly in the case where (M¯,g¯) is an Einstein manifold. These bounds facilitate the characterization of slices in GRW spacetimes. In addition, we use the vector field ∂t and the so-called support function θ to derive generalized Minkowski-type integral formulas for compact Riemannian and spacelike hypersurfaces. These formulas are applied to establish, under certain conditions, results concerning the existence or non-existence of such compact hypersurfaces with scalar curvature, either bounded from above or below.

Sequential mediation model of social support, care burden, and internalized stigma among family function and depression in caregivers of patients with schizophrenia: evidence from a cross-sectional study in southwest China.

There is a lack of comprehensive measurements and systematic evaluations of the depression in caregivers of patients with psychiatric disorders and the factors influencing them in China. This study aims to explore the relationship between family function and depression in caregivers of patients with schizophrenia at the individual, family, and social levels according to the ecological system theory and attachment theory. In this study, multi-stage, stratified cluster sampling was adopted to sample caregivers of patients with schizophrenia as subjects from one to three counties of four counties in Yunnan, from September 2022 to March 2023. Collecting the current caregiver's demographic data, family functions, social support, care burden, depression and internalized stigma. The results of single-factor analysis show that age, education level, relationship with patients, and the degree of self-care of patients are the influencing factors of depression of people living with schizophrenia (p < 0.05). The scores of self-rating depression scale are higher for caregivers who have not received formal education, caregivers who cannot take care of themselves and the parents, spouses and children of patients. The results of Pearson correlation analysis show that depression is positively associated with internalized stigma and care burden, and negatively associated with social support and family function (p < 0.05). The results of multiple linear regression show that after controlling age, education level, the patient's self-care capacity, and relationship with patient, the internalized stigma (β = 0.184, p = 0.01) is positively correlated with depression. The mediation effect route of family function → social support → care burden → internalized stigma → depression was significant with 95% confidence interval [-0.150, -0.01], and the chained mediation effect was 5.904%. To reduce the depression level in family caregivers of schizophrenia, apart from taking measures to improve the caregiver's family function, enhancing social support, decreasing care burden, and reducing internalized stigma are suggested.

Selective Synthesis of 3D Aligned VO2 and V2O5 Carbon Nanotube Hybrid Materials by Chemical Vapor Deposition.

3D carbon nanotube hybrid materials containing VO2 and V2O5 evenly distributed onto vertically aligned carbon nanotubes (VACNTs) is reported. Adjustable loading of particles in controllable sizes onto the VACNTs was developed via a stepwise chemical vapour deposition (CVD) approach. Solid VO(acac)2 is chosen as vanadium source. CO2 acts as reactive gas for the pre-functionalisation of the VACNTs. The process temperature was identified as key parameter to control the deposited vanadium oxide phase. A temperature of 550°C results in monoclinic VO2, while 600 °C results in the deposition of V2O5 onto the VACNT support. The morphology and the amount of deposited material was found to be dependent on the reactor dimensions and the degree of functionalization of the carbon support. An increase of the D/G ratio of the VACNT from 0.75 to 1.08 caused by a CO2 treatment step within the process led to an increase of the particle coverage from a scarce coverage without prior CO2 treatment to a dense coverage of the VACNT support after 15 min of CO2 exposure time. Size and crystallinity of the as deposited particles can be further adjusted by a controlled heat treatment after VO(acac)2 precursor deposition.

Measuring ecological effects and policy mechanisms of urban land use transition – a case study of Xi'an, China

ABSTRACT Measuring ecological effects and policy mechanisms of urban Land Use Transition (LUT) is the key to understanding regional environmental changes and achieving sustainable urban developments. This paper illustrates and demonstrates a formal method for measuring the ecological effect of LUT characterized by Ecological Security Index (ESI) and Ecosystem Value (ESV), and enhanced with a correlational analysis between the ecological effect model and urban policy mechanism. Using Xi'an, a major capital city of western China as a case study, based on multi-temporal Thematic Mapper (TM) remote sensing images, Digital Elevation Model (DEM) and relevant statistical data, the results show that the method using ESI and ESV, together with the Land Use Transition Probability Matrix (LUTPM) can comprehensively measure the ecological effects of LUT process in Xi'an from 2000 to 2020. The results show that due to the impact of urban expansion, regional construction land increased significantly (by 67.07%), while farmland decreased considerably (by 13.12%). The farmland and forestland around the main urban area of Xi'an were centrally converted into construction land, yet the mutual transition of other types of land was relatively scattered. The total amount of ESV has slightly increased from 40.1 billion yuan to 42.8 billion yuan, and the proportion of ecological service function value presents a decreasing trend in regulation function (65%), support function (22%), supply function (9%), and cultural function (4%). The ESI value slightly decreased from 0.517 to 0.512, and overall it is still in a state of ecological security. The trend of ESV and ESI decreasing from mountainous areas to plains indicates that high-intensity human activities in plain areas have had a significant impact on the ecological environment. The correlation analysis between policy mechanisms and ecological effects indicates that ecological protection policies have improved the ecological environment and maintain ecological security (high ESV-high ESI mode), and may also have limited economic activities and been detrimental to the security of urban composite ecosystems (high ESV-low ESI mode). Spatial expansion policies have driven the rapid growth of construction land and threatened ecological security (low ESV-low ESI mode). Zoning adjustment policies have led to the transformation of ecological land to construction land, threatening ecological security and reducing ESV (low ESV-low ESI mode), and may also have promoted industrial upgrading and economic development, providing economic assurance for improving ecological security (low ESV-high ESI mode). These comprehensive findings provide valuable insights for understanding the ecological effects and policy mechanisms of LUT in Xi'an for achieving sustainable urban development, and demonstrate and explore a novel method to more appropriately and effectively measure LUT by combining ESV and ESI.
