The Sequential Direct and Indirect Effects of Mountain Uplift, Climatic Niche, and Floral Trait Evolution on Diversification Dynamics in an Andean Plant Clade.

Why and how organismal lineages radiate is commonly studied through either assessing abiotic factors (biogeography, geomorphological processes, and climate) or biotic factors (traits and interactions). Despite increasing awareness that both abiotic and biotic processes may have important joint effects on diversification dynamics, few attempts have been made to quantify the relative importance and timing of these factors, and their potentially interlinked direct and indirect effects, on lineage diversification. We here combine assessments of historical biogeography, geomorphology, climatic niche, vegetative, and floral trait evolution to test whether these factors jointly, or in isolation, explain diversification dynamics of a Neotropical plant clade (Merianieae, Melastomataceae). After estimating ancestral areas and the changes in niche and trait disparity over time, we employ Phylogenetic Path Analyses as a synthesis tool to test eleven hypotheses on the individual direct and indirect effects of these factors on diversification rates. We find strongest support for interlinked effects of colonization of the uplifting Andes during the mid-Miocene and rapid abiotic climatic niche evolution in explaining a burst in diversification rate in Merianieae. Within Andean habitats, later increases in floral disparity allowed for the exploitation of wider pollination niches (i.e., shifts from bee to vertebrate pollinators), but did not affect diversification rates. Our approach of including both vegetative and floral trait evolution, rare in assessments of plant diversification in general, highlights that the evolution of woody habit and larger flowers preceded the colonization of the Andes, but was likely critical in enabling the rapid radiation in montane environments. Overall, and in concert with the idea that ecological opportunity is a key element of evolutionary radiations, our results suggest that a combination of rapid niche evolution and trait shifts was critical for the exploitation of newly available niche space in the Andes in the mid-Miocene. Further, our results emphasize the importance of incorporating both abiotic and biotic factors into the same analytical framework if we aim to quantify the relative and interlinked effects of these processes on diversification.

Loss of grazing by large mammalian herbivores can destabilize the soil carbon pool.

Grazing by mammalian herbivores can be a climate mitigation strategy as it influences the size and stability of a large soil carbon (soil-C) pool (more than 500 Pg C in the world's grasslands, steppes, and savannas). With continuing declines in the numbers of large mammalian herbivores, the resultant loss in grazer functions can be consequential for this soil-C pool and ultimately for the global carbon cycle. While herbivore effects on the size of the soil-C pool and the conditions under which they lead to gain or loss in soil-C are becoming increasingly clear, their effect on the equally important aspect of stability of soil-C remains unknown. We used a replicated long-term field experiment in the Trans-Himalayan grazing ecosystem to evaluate the consequences of herbivore exclusion on interannual fluctuations in soil-C (2006 to 2021). Interannual fluctuations in soil-C and soil-N were 30 to 40% higher after herbivore exclusion than under grazing. Structural equation modeling suggested that grazing appears to mediate the stabilizing versus destabilizing influences of nitrogen (N) on soil-C. This may explain why N addition stimulates soil-C loss in the absence of herbivores around the world. Herbivore loss, and the consequent decline in grazer functions, can therefore undermine the stability of soil-C. Soil-C is not inert but a very dynamic pool. It can provide nature-based climate solutions by conserving and restoring a functional role of large mammalian herbivores that extends to the stoichiometric coupling between soil-C and soil-N.

Dynamic path analysis for exploring treatment effect mediation processes in clinical trials with time-to-event endpoints.

Why does a beneficial treatment effect on a longitudinal biomarker not translate into overall treatment benefit on survival, when the biomarker is in fact a prognostic factor of survival? In a recent exploratory data analysis in oncology, we were faced with this seemingly paradoxical result. To address this problem, we applied a theoretically principled methodology called dynamic path analysis, which allows us to perform mediation analysis with a longitudinal mediator and survival outcome. The aim of the analysis is to decompose the total treatment effect into a direct treatment effect and an indirect treatment effect mediated through a carefully constructed mediation path. The dynamic nature of the underlying methodology enables us to describe how these effects evolve over time, which can add to the mechanistic understanding of the underlying processes. In this paper, we present a detailed description of the dynamic path analysis framework and illustrate its application to survival mediation analysis using simulated and real data. The use case analysis provides clarity on the specific exploratory question of interest while the methodology generalizes to a wide range of applications in drug development where time-to-event is the primary clinical outcome of interest.

Path analysis reveals combined winter climate and pollution effects on the survival of a marine top predator.

Marine ecosystems are experiencing growing pressure from multiple threats caused by human activities, with far-reaching consequences for marine food webs. Determining the effects of multiple stressors is complex, in part, as they can affect different aspects of biological organisation (behaviour, individual traits and demographic rates). Determining the combined effects of stressors, through different biological pathways, is key to predict the consequences for the viability of populations threatened by global change. Due to their position in the food chain, top predators such as seabirds are considered more sensitive to environmental changes. Climate change is affecting the prey resources available for seabirds, through bottom-up effects, while organic pollutants can bioaccumulate in food chains with the greatest impacts on top predators. However, knowledge of their combined effects on population dynamics is scarce. Using a path analysis, we quantify the effects of climate change and pollution on the survival of adult great black-backed gulls, both directly and through effects of individuals' body mass. Warmer ocean temperatures in gulls' winter foraging areas in the North Sea were correlated with higher survival, potentially explained by shifts in prey availability associated with global climate change. We also found support for indirect negative effects of organochlorines, highly toxic pollutants to seabirds, on survival, which acted, in part, through a negative effect on body mass. The results from this path analysis highlight how, even for such long-lived species where variance in survival tends to be limited, two stressors still have had a marked influence on adult survival and illustrate the potential of path models to improve predictions of population variability under multiple stressors.

Composition and influencing factors of hospitalization expenses for epilepsy patients based on path analysis.

OBJECTIVE: This study aimed to understand the composition and influencing factors of epilepsy patients' hospitalization expenses, thus providing a reference for reducing the disease burden of epilepsy patients in low- and middle-income developing countries. METHODS: A total of 4206 hospitalized cases of epilepsy from 2018 to 2020 were collected. Descriptive statistics were used to understand the patient cost composition, path analysis was used to understand the direct and indirect factors of hospitalization expenses. RESULTS: From 2018 to 2020, the average hospitalization expenses for epilepsy patients was 4,299.93 RMB yuan, and the average length of stay was 2.47 days. The highest proportion of hospitalization expenses was diagnosis costs (> 50%), followed by comprehensive medical service costs and drug costs. In terms of the total effect coefficient, the major factors affecting the hospitalization expenses were length of stay (0.880), emergency admission(0.463), and the comorbidities and complications(> 0.250). Hospital length of stay, discharge mode(death) and number of hospitalizations(2 times) affect hospitalization expenses through direct effect. Long-term hospitalization (> 30 days), admission routes(emergency), the comorbidities and complications, presence of drug allergy, and age also affect hospitalization expenses through indirect effects. CONCLUSION: Diagnosis costs and length of stay are important factors affecting the medical expenses of epilepsy inpatients. In general, the quality control of the hospital is good, but it still needs to standardize the diagnosis and treatment behavior of medical staff through the clinical path.

Hydrothermal carbonisation of polyvinyl chloride in ethanol-water/water system for solid fuels: Dechlorination, characteristics analysis of hydrochar, and reaction path.

Polyvinyl chloride (PVC) waste plastic is a typical solid waste. In this paper, the dechlorination and carbonization behavior of PVC in ethanol-water/water system under different process parameters (temperature, residence time, solid-liquid ratio) was studied, and hydrothermal carbon was characterized by SEM, elemental analysis, TG-DTG, XPS, Py-GC/MS. The results show that temperature is the key to the hydrothermal dechlorination of PVC, and the dechlorination efficiency of PVC is the highest by parameter optimization (220°C-90 min-10% S/D-80% E/D), which can reach 96.33 %. With the removal of Cl, the surface of the PVC matrix changed from full and smooth flocculent to honeycomb with uniform pore size distribution. Thermogravimetric analysis shows that the combustion of hydrochar can be divided into three stages: HCl precipitation and volatile combustion, semi-coke and coke combustion, and fixed carbon combustion. The combustion parameters and kinetic parameters of hydrochar were measured, and it was found that the hydrothermal carbonization of PVC at higher temperatures and ethanol-water ratio could improve the combustion performance of hydrochar. The highest calorific value can reach 36.68 MJ/mol. Py-GC/MS analyzed the distribution of the pyrolysis products, and alkylbenzene and aliphatic were the main products of pyrolysis. The structural analysis of hydrochar showed that C-C and CC accounted for the largest proportion, accompanied by a small amount of C-O and CO and trace C-Cl. The possible reaction mechanism of the hydrothermal carbonization of PVC was analyzed based on the distribution of functional groups and compound composition. This work provides an effective and sustainable method for the recycling of refractory chlorinated plastics.

Family communication and courageous coping in Korean adolescents and young adults: a cross-sectional study.

OBJECTIVE: Adolescents and young adults (AYAs) with cancer are a vulnerable population during a critical developmental transition that can benefit from the adoption of courageous coping. Parental support is crucial in enhancing adjustment and coping skills. The linkage between parent-adolescent communication (PAC) and the use of courageous coping (UCC), however, remains unclear. This study examined the association between PAC and UCC and possible mediators of this relationship among Korean AYAs with cancer. METHODS: In this cross-sectional, correlational study, self-report data were collected from 144 AYAs aged 11-26 years. A path analytic approach was employed using a hierarchical regression model to test for the direct relationship between PAC and UCC and the indirect effects of a proposed primary mediator (family cohesion) and two intermediary mediators (uncertainty of illness, hope) on PAC-UCC relationship. RESULTS: The mean age of the sample was 17 years (SD = 3.8), with 42% currently receiving cancer treatment. Greater PAC was significantly associated with increased UCC (mother figure: p = .0024, father figure: p = .0042). Increased family cohesion significantly mediated the PAC-UCC relationship, indicated by a diminished PAC-UCC relationship after controlling for family cohesion (mother: p = .2753; father: p = .8107). Mediated mediation models indicated that increased hope stemming from decreased uncertainty was the mechanism through which family cohesion impacted the PAC-UCC relationship. CONCLUSIONS: Findings underscore that greater PAC can facilitate UCC among Korean AYAs with cancer and provide insights for therapeutic parent-child communication. Results further demonstrate the complex mediating role of fostering family cohesion, reducing uncertainty, and fostering hope can play in the PAC-UCC relationship.

Psychological pathway to emotional exhaustion among nurses and midwives who provide perinatal bereavement care in China: a path analysis.

BACKGROUND: A lack of confidence in perinatal bereavement care (PBC) and the psychological trauma experienced by nurses and midwives during bereavement care leads to their strong need for sufficient organisational support. The current study intended to test a hypothesised model of the specific impact paths among organisational support, confidence in PBC, secondary traumatic stress, and emotional exhaustion among nurses and midwives. METHODS: A descriptive, cross-sectional survey was conducted in sixteen maternity hospitals in Zhejiang Province, China, from August to October 2021. The sample (n = 779) consisted of obstetric nurses and midwives. A path analysis was used to test the relationships among study variables and assess model fit. RESULTS: Organisational support directly and positively predicted confidence in PBC and demonstrated a direct, negative, and significant association with secondary traumatic stress and emotional exhaustion. Confidence in PBC had a positive direct effect on secondary traumatic stress and a positive indirect effect on emotional exhaustion via secondary traumatic stress. Secondary traumatic stress exhibited a significant, direct effect on emotional exhaustion. CONCLUSIONS: This study shows that nurses' and midwives' confidence in PBC and mental health were leadingly influenced by organisational support in perinatal bereavement practice. It is worth noting that higher confidence in PBC may lead to more serious psychological trauma symptoms in nurses and midwives. Secondary traumatic stress plays an essential role in contributing to emotional exhaustion. The findings suggest that support from organisations and self-care interventions were required to improve confidence in PBC and reduce negative psychological outcomes among those providing PBC. The development of objective measures for assessing competence in PBC and organizational support are essential.

Factors associated with urinary retention after vaginal delivery under intraspinal anesthesia: a path analysis model.

INTRODUCTION AND HYPOTHESIS: Women who have intraspinal anesthesia for delivery are more likely to experience postpartum urinary retention (PUR), which, if not recognized and treated promptly, can result in long-term urinary dysfunction. Many factors influencing PUR have been proposed, but no study has been conducted to investigate the relationship between them. This study is aimed at determining the influencing factors of PUR and to explore the relationship between them. METHODS: A prospective, cross-sectional survey using self-made questionnaires was conducted among 372 puerperae in a Grade A hospital in Guangzhou, China, from April to September 2022. SPSS25.0 and AMOS24.0 were used for data analysis, and a path analysis model was established to determine the relationship between the influencing factors. RESULTS: The incidence of PUR was 49.85%. Residence, the level of postpartum pain, and the change of postnatal urination position had a direct effect on PUR. Episiotomy and analgesic duration have both direct and indirect effects on PUR. Forceps delivery, perineal edema and oxytocin had an indirect effect on PUR. Variables could influence the occurrence of PUR by mediating the analgesic duration, episiotomy, postpartum pain level, and postnatal urination position changes. CONCLUSIONS: This study provides an empirical model to illustrate the relationship between PUR and related factors in women who delivered under intraspinal anesthesia. In future management, more attention should be paid to women who live in cities, have higher levels of postpartum pain, longer analgesic duration, higher grade of perineal edema, and received episiotomy, forceps delivery, and oxytocin during labor.

Explaining maternal antenatal attachment by psychological, clinical and sociodemographic factors: a path analysis study.

BACKGROUND: Antenatal attachment is a fundamental concept relative to human transition to parenthood and may be influenced by several factors. The aim of this study is to find the best model to explain maternal antenatal attachment based on the interaction among sociodemographic, clinical, and psychological variables. METHODS: Pregnant women (N = 407) were interviewed during the second trimester of pregnancy while waiting for medical consultations. A sociodemographic, obstetric, and psychometric protocol was used. STATISTICAL ANALYSES: path analysis. INDEPENDENT VARIABLES: psychopathological symptomatology, depression, anxiety, stress, occupational stress, attitudes about pregnancy and motherhood, coping styles, marital satisfaction, sociodemographic, and clinical variables. DEPENDENT VARIABLES: maternal antenatal attachment in its several dimensions; quality of attachment (QA), intensity of preoccupation (IP), and global attachment (GA). RESULTS: Depression, anxiety, attitudes, and marital satisfaction explained 37% of maternal antenatal QA. Age, depression, anxiety, attitudes, and marital satisfaction explained 26% of maternal antenatal IP. Age, depression, anxiety, attitudes, and marital satisfaction explained 34% of the statistical variance of maternal antenatal GA. CONCLUSIONS: Factors like emotional states (depression and anxiety), attitudes towards pregnancy and motherhood, marital satisfaction, and a sociodemographic variable (age) contribute significantly for the explanation of maternal antenatal attachment.

Determinants of sedentary behavior in community-dwelling older adults with type 2 diabetes based on the behavioral change wheel: a path analysis.

BACKGROUND: Sedentary behavior (SB) is deeply ingrained in the daily lives of community-dwelling older adults with type 2 diabetes mellitus (T2DM). However, the specific underlying mechanisms of the determinants associated with SB remain elusive. We aimed to explore the determinants of SB based on the behavior change wheel framework as well as a literature review. METHODS: This cross-sectional study recruited 489 community-dwelling older adults with T2DM in Jinan City, Shandong Province, China. Convenience sampling was used to select participants from relevant communities. This study used the Measure of Older Adults' Sedentary Time-T2DM, the Abbreviated-Neighborhood Environment Walkability Scale, the Social Support Rating Scale, the Lubben Social Network Scale 6, the Subjective Social Norms Questionnaire for Sedentary Behavior, the Functional Activities Questionnaire, the Numerical Rating Scale, the Short Physical Performance Battery, and the Montreal Cognitive Assessment Text to assess the levels of and the determinants of SB. Descriptive statistical analysis and path analysis were conducted to analyze and interpret the data. RESULTS: Pain, cognitive function, social isolation, and social support had direct and indirect effects on SB in community-dwelling older adults with T2DM (total effects: ß = 0.426, ß = -0.171, ß = -0.209, and ß = -0.128, respectively), and physical function, walking environment, and social function had direct effects on patients' SB (total effects: ß = -0.180, ß = -0.163, and ß = 0.127, respectively). All the above pathways were statistically significant (P < 0.05). The path analysis showed that the model had acceptable fit indices: RMSEA = 0.014, χ 2/df = 1.100, GFI = 0.999, AGFI = 0.980, NFI = 0.997, RFI = 0.954, IFI = 1.000, TLI = 0.996, CFI = 1.000. CONCLUSION: Capability (physical function, pain, and cognitive function), opportunity (social isolation, walking environment, and social support), and motivation (social function) were effective predictors of SB in community-dwelling older adults with T2DM. Deeper knowledge regarding these associations may help healthcare providers design targeted intervention strategies to decrease levels of SB in this specific population.

Structural equation modeling analysis of factors influencing decisional conflict between dialysis modality among end-stage kidney disease patients in Wuhan.

OBJECTIVES: To explore the influencing factors and relationships associated with decisional conflict of dialysis modality in End-stage kidney disease (ESKD) patients. METHODS: This study was a survey-based cross-sectional investigation conducted on 150 ESKD patients in a third-class hospital in Wuhan. The general information questionnaire, decisional conflict scale, Montreal cognitive assessment, frail scale, perceived social support scale, and brief health literacy screen were used for investigation. SPSS 25.0 was used to compare the differences between the decisional and non-decisional conflict groups, and AMOS 23.0 was used to construct a structural equation model to explore the influencing factors. RESULTS: The incidence of decisional conflict in 150 ESKD patients was 33.3% (50/150). Binary logistic regression analysis showed that the independent risk factors for decisional conflict of dialysis modality in ESKD patients included monthly household income (OR = 0.184), cognitive function (OR = 7.0), social support (OR = 0.891), health literacy (OR = 0.608), the level of eGFR (OR = 1.488), and the level of cTnI (OR = 9.558). The constructed path analysis model had a good fit (x2/df = 1.499, GFI = 0.957, AGFI = 0.911, NFI = 0.906, CFI = 0.967, RMSEA = 0.055). The path analysis showed that health literacy (0.577) had the greatest impact on the decisional conflict, with a direct effect of 0.480 and an indirect effect of 0.097 through cognitive function and monthly household income. Next was social support, with an effect value of 0.434. CONCLUSIONS: In clinical practice, it is important to enhance the health literacy of patients and their families and to provide advanced education on dialysis plans. Additionally, in managing and planning chronic kidney disease progression and dialysis, it is recommended to regularly and systematically assess cognitive function, particularly before the patient's cognitive impairment worsens or the severity of the disease progresses. Advanced care planning can be established through collaboration between healthcare professionals and patients to ensure appropriate decision-making and management. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: This paper finds that the factors that influence and relate to dialysis methods in end-stage renal disease patients help nurses exercise autonomy better, assist patients in reducing their decisional conflict, and improve clinical outcomes. PATIENT OR PUBLIC CONTRIBUTION: Patients received a relevant questionnaire survey, and caregivers assisted in conducting the study.

The relationship between good governance, social support, and perceived discrimination with mental health through the mediation role of quality of life: a cross-sectional path analysis in Iran.

BACKGROUND: Recognizing the established link between social determinants of health, such as social support, good governance, and perceived discrimination, and individual mental health, this study aims to delve deeper into the specific relationships within the Iranian adult population. It seeks to elucidate the potential mediating role of quality of life in the association between mental health disorders (MHDs) and these social factors. METHODS: This cross-sectional study employed path analysis to investigate the relationships between social determinants of health and MHDs among 725 Iranian adults in Tabriz, Northwest Iran. Data collection occurred between March and September 2022, utilizing a multi-stage and cluster sampling approach. Good governance, social support, perceived discrimination, MHDs, and quality of life were assessed using valid questionnaires. Statistical analysis was conducted using SPSS-24 and Lisrel-8 software, with a significance level set at p < 0.05. RESULTS: This study found that nearly 70.0% of the participants reported experiencing mental health problems. The path analysis showed that good governance had a significant indirect and negative effect on MHDs via quality of life (ß = -0.05; P < 0.05). Major racial discrimination had a positive relationship in the direct and indirect paths (ß = 0.24; P < 0.01). While, social support was a directly and indirectly significant predictor of decreased MHDs (ß = -0.17, p < 0.01). Furthermore, quality of life had a negative relationship on the indirect path with MHDs (ß = -0.24, P < 0.01). CONCLUSIONS: This study reveals a significant burden of mental health issues among Iranian adults. It highlights the crucial role of social factors like good governance, social support, and perceived discrimination in shaping mental health through their impact on quality of life. Consequently, addressing these factors through improved governance, strengthened social support systems, and active efforts to reduce discrimination is essential for promoting mental well-being.

Factors associated with intention of HIV testing among Asian American men: a path analysis.

Research has pointed to myriad cultural and socio-psychological factors associated with HIV testing, such as acculturation, social norms about HIV testing, masculinity, homonegativity, and constructs from the Theory of Planned Behavior. However, the interrelationships of these factors on the intentions of HIV testing among the population of Asian American men remains unknown. A dataset of 425 Asian American men in the U.S., collected online with convenience sampling method during 2020-2021, was analyzed to test a conceptual framework that aimed to fill this gap. Results from a path model with two endogenous variables (homonegativity and HIV testing intention) indicated that perceived social norms about HIV testing, attitude about HIV testing, and perceived HIV risk had directandindirect relationships with the intentions of HIV testing in the study population. However, social norms about HIV testing and perceived HIV risk showed stronger direct effects (standardized estimates = 0.37 and 0.34, respectively, p-value < 0.001). Additionally, we found that the relationships of these factors with HIV testing intention were also mediated by homonegativity. Findings from this study advance our understanding of pathways of associations between a host of cultural and socio-psychological factors with HIV testing intention among an understudied population - Asian American men. Our results will help inform the development of future intervention programs to increase HIV testing in this population.

Disentangling the link between social determinants of health and child survival in Nigeria during the Sustainable Development Goals era: a hierarchical path analysis of time-to-event outcome.

While social determinants of health have been perennially linked to child survival in resource-limited countries, the precise and tested pathways to effect are not clearly understood. The objective of this study was therefore to identify the critical pathways as posited a priori in a model through which social factors (at maternal, household, and community levels) determine neonatal, infant, and under-five mortalities in Nigeria. Using a novel analytic approach (hierarchical path modelling for predicting accelerated failure time) to estimate (in)direct and total effects of social determinants of child survival, we analysed 30,960 live births (weighted data for representativeness), obtained from the 2016/2017 Nigeria Multiple Indicator Cluster Survey. There were three outcome variables: time until occurrence of neonatal, infant, and under-five mortalities. The independent variables were layered factors related to child, maternal, household and community. Geographical region, rurality of residence, infrastructural development, maternal education, contraceptive use, marital status, and maternal age at birth were found to operate more indirectly on neonatal, infant, and under-five survival. Child survival is due to direct effects of child's sex (female), gestational type (singleton), birth spacing (children whose mothers delivered at least two years apart), and maternal age at delivery (20-34 years). According to the path coefficients, the indirect effects of geographical regions are the most influential determinants of child survival, accounting for 30% (neonatal), 37.1% (infant) and 39.9% (under-five) of the total effects. This study offers comprehensive set of factors, and linked pathways, at the maternal, household, and community levels that are associated with child survival in Nigeria. To accelerate progress towards Sustainable Development Goal targets for child survival and reduce geographical inequities, stakeholders should implement more impactful policies that promote maternal education, contraceptive use and improve living conditions of women (especially in rural areas of northern Nigeria). Future research should focus on identifying the most effective interventions for addressing these social determinants of child survival in Nigeria.

Direct and indirect predictors of postpartum depression symptoms among indigenous Bedouin mothers in Israel.

Postpartum depression (PPD) is a common and complex phenomenon with negative outcomes for children, women and their families. This study set out to identify both direct and indirect predictors of PPD symptoms among indigenous Bedouin mothers in Israel. The study included 305 women, 18 to 45 years of age, who were interviewed while pregnant and again, 2 to 4 months postpartum. Interviews were conducted in Arabic and included the Edinburgh Postnatal Depression Scale, administered at both points of measurement. Using path analyses, we identified four significant, direct predictors of PPD symptoms. The strongest was depressive symptoms when pregnant, followed by low relative income, low hemoglobin, and number of prior miscarriages. The latter was significantly associated with consanguinity, meaning that women married to a first cousin experienced more miscarriages which, in turn, increased PPD risk. Low relative income was the only variable that had both a direct and indirect effect upon PPD symptoms (via symptoms of depression when pregnant and hemoglobin). Education and polygamy also emerged as indirect predictors of PPD via depressive symptoms reported during pregnancy. Results suggest a high rate of PPD in this perinatal sample of indigenous women. Our findings underscore the need for tailored interventions to reduce PPD, especially for low-income Bedouin women, faced with many barriers and insufficient access to healthcare services.

Knowledge Development Trajectories of Intelligent Video Surveillance Domain: An Academic Study Based on Citation and Main Path Analysis.

Smart city is an area where the Internet of things is used effectively with sensors. The data used by smart city can be collected through the cameras, sensors etc. Intelligent video surveillance (IVS) systems integrate multiple networked cameras for automatic surveillance purposes. Such systems can analyze and monitor video data and perform automatic functions required by users. This study performed main path analysis (MPA) to explore the development trends of IVS research. First, relevant articles were retrieved from the Web of Science database. Next, MPA was performed to analyze development trends in relevant research, and g-index and h-index values were analyzed to identify influential journals. Cluster analysis was then performed to group similar articles, and Wordle was used to display the key words of each group in word clouds. These key words served as the basis for naming their corresponding groups. Data mining and statistical analysis yielded six major IVS research topics, namely video cameras, background modeling, closed-circuit television, multiple cameras, person reidentification, and privacy, security, and protection. These topics can boost the future innovation and development of IVS technology and contribute to smart transportation, smart city, and other applications. According to the study results, predictions were made regarding developments in IVS research to provide recommendations for future research.

Analyzing symptom experiences and pathways to enhancing quality of life in adolescents with Moyamoya disease.

PURPOSE: The psycho-emotional symptom experiences and health-related factors that influence the quality of life of adolescents with Moyamoya disease are still not fully understood. The aim of this study is to identify the daily physical and accompanying psychological symptom experiences of such adolescents, and to examine how health-related factors contribute to their quality of life. DESIGN AND METHOD: This study employed a descriptive cross-sectional research design. Data on a total of 134 adolescents with Moyamoya disease was analyzed in order to develop a path analysis. Data were collected from October 2019 to January 2021 in South Korea. The theory of salutogenesis was employed in order to develop a hypothetical model for this path analysis. Participants were given a self-reporting questionnaire. Descriptive analysis and path analysis were conducted based on the results. RESULTS: Adolescents with Moyamoya disease experienced several negative emotions simultaneously, regardless of the severity of their physical symptoms. The path analysis revealed that stress, a sense of coherence, behavior, and the support of friends were significant contributors to adolescents' quality of life. CONCLUSIONS: Adolescents with Moyamoya disease have multifaceted symptom experiences in their daily lives. To enhance their quality of life, it is crucial to provide support that can help strengthen their capacity for stress management and enhance their sense of coherence. PRACTICAL IMPLICATIONS: This study provides evidence that nurses should offer anticipatory information to adolescents with Moyamoya disease regarding the symptoms they will frequently encounter, and develop interventions to enhance their quality of life.

How to improve the energy-saving performance of China's transport sector? An input-output perspective.

The transport sector proves a major energy consumer in China, but improving energy-saving performance in China's provincial transport sector from the lifecycle perspective remains unresolved. Thus, this study employs the environmentally extended multi-region input-output (MRIO) method, structural path analysis, and the newest MRIO table of China from 2017, to investigate how to improve the energy-saving performance from final demand structure, supply chain, and pathway perspectives. The relevant results are threefold. (1) Regarding the final demand structure level, the embodied energy consumption of China's transport sector is predominantly driven by investment from the production side, while that of the consumption side is primarily caused by exports. (2) At the supply chain level, production-side embodied energy consumption primarily occurs along a three-echelon supply chain, while that from the consumption side mostly occurs via a two-echelon supply chain. (3) At the pathway level, the production-side energy-saving performance of China's provincial transport sector is dominated by two pathways along the construction sector, including transport sector → construction sector → final demands, and transport sector → intermediate inputs → construction sector → final demands, while that of the consumption side is chiefly determined by three pathways along internal transportation chains.

Do astigmatid teeth matter: a tribological review of cheliceral chelae in co-occuring mites from UK beehives.

The dentition of the chelal moveable digit in cohabiting astigmatids from UK beehives (i.e., Carpoglyphus lactis (Linnaeus), Glycyphagus domesticus (DeGeer), and Tyrophagus putrescentiae (Schrank)) is characterised for the first time using quantitative tribological measures within a 2D mechanical model. The trophic function of astigmatid chelae are reviewed in terms of macroscopic tools used by humans including hooking devices, pliers, shears, rasps and saws. Comparisons to oribatid claws and isopod dactyli are made. The overall pattern of the moveable digit form of T. putrescentiae is not just a uniformly shrunken/swollen version between the other two taxa at either the macro- or micro-scale. Mastication surface macro-roughness values are in the range of international Roughness Grade Numbers N5-N6. The moveable digit of C. lactis has low rugosity values compared to the glycyphagid and acarid (which are topographically more similar and match that roughness typical of some coral reef surfaces). C. lactis has the most plesiomorphic moveable digit form. The mastication surface of all three species as a chewing tool is distinctly ornamented despite the moveable digit of C. lactis looking like a bar-like beam. The latter has more opportunities to be a multifunctional tool behaviourally than the other two species. Little evidence of any differences in the 'spikiness' of any 'toothiness' is found. Some differences with laboratory cultured specimens are found in C. lactis and possibly T. putrescentiae suggesting where selection on the digit may be able to occur. The chelal surface of T. putrescentiae has been deformed morphologically during evolution the most, that of C. lactis the least. Repeated localised surface differentiation is a feature of the moveable digit in G. domesticus compared to the likely more concerted changes over certain nearby locations in T. putrescentiae. An impactful chelal teeth design is present in G. domesticus but this is more equivocal in T. putrescentiae. Pockets within the mastication surface of the glycyphagid (and to some extent for the acarid) may produce foodstuff crunch forces of the scale of the chelal tips of oribatids. The moveable digit dentition of G. domesticus is adapted to shred foodstuff (like a ripsaw) more than that of the grazing/shearing dentition of T. putrescentiae. The collecting 'picker' design of C. lactis posterior teeth matches the size of Bettsia alvei hyphae which attacks hive-stored pollen. Detritus accumulated in chelal digit gullets through a sawing action matches the smallest observed ingested material. The dentition of C. lactis should produce less friction when moving through food material than G. domesticus. C. lactis is the most hypocarnivorous and may 'skim' through fluids when feeding. Astigmatid teeth do matter. The three commensal species can avoid direct competition. Future work is proposed in detail.
