Published: September 2024

Abstract

Purpose The objective of this study is to examine the influence of exercise adherence on the life satisfaction of rural left-behind children and to investigate the mediating effects of school bullying and loneliness. The findings will provide a theoretical and practical foundation for enhancing the life satisfaction of rural left-behind children through exercise adherence. Methods A total of 472 left-behind children in five rural primary and middle schools in Hubei Province were surveyed using the Exercise Adherence Scale (SEA), Satisfaction with Life Scale (SWLS), Victim Questionnaire(VQ), and Children's Loneliness Scale (CLS). The relevant data were then subjected to statistical and analytical analysis using the correlation analysis method, the multiple regression analysis method, and the Bootstrap test method. Results The relationship between the four variables of exercise adherence, school bullying, loneliness, and life satisfaction among rural left-behind children was significant, and the results of multiple regression analysis showed that exercise adherence significantly and positively predicted life satisfaction (β = 0.451, P < 0.01); exercise adherence had a significant negative predictive effect on school bullying (β=-0.258, P < 0.01) and loneliness (β=-0.329, P < 0.01) negatively predicted significantly, school bullying positively predicted loneliness significantly (β = 0.269, P < 0.01), school bullying negatively predicted life satisfaction significantly (β=-0.098, P < 0.05); and loneliness negatively predicted life satisfaction significantly (β=-0.415, P < 0.01).Bootstrap test results show that:The direct effect of exercise adherence on the life satisfaction of rural left-behind children is significant, with an effect value of 0.436, and the proportion of the direct effect is 57.80%; the mediating effect of school bullying between exercise adherence and life satisfaction is significant, with an effect value of 0.042, and the proportion of the mediating effect is 5.62%; the mediating effect of loneliness between exercise adherence and life satisfaction is significant, with an effect value of 0.228, and the percentage of mediation effect is 30.20%; the chain mediation effect of school bullying and loneliness between exercise adherence and life satisfaction is significant, the effect value is 0.048, and the percentage of mediation effect is 6.82%, and the percentage of indirect effect is 43.20%. Conclusion Exercise adherence can enhance life satisfaction of rural left-behind children by reducing the incidence of school bullying and loneliness.
Kinetics and mechanism of the uncatalyzed and copper (II) catalyzed color removal of thionine and methyl violet dyes in presence of hydrogen peroxide

Published: September 2024

Abstract

In aqueous solutions, the kinetics of the color removal of two cationic dyes, thionine and methyl violet, both catalyzed by copper (II) ions and uncatalyzed have been studied. The progress of the reaction was seen by tracking the decay in absorbance at λmax = 600 and 584 nm for methyl violet and thionine, respectively. The rate of an uncatalyzed reaction increased progressively as the starting peroxide concentration [H2O2]o increased, peaking at 0.8 M for thionine and 2.0 M for methyl violet, respectively. However, for the catalyzed reactions, the rate of reaction rose as [H2O2]o increased, peaking at ≈ 0.4 and 2.0 for methyl violet and thionine, respectively, before declining. The creation of the extremely active and non-selective hydroxyl radicals produced by the reaction of hydrogen peroxide with copper (II) ions was thought to be the source of the catalytic action of copper (II) ions. However, a first order dependence with respect to the original dye concentration was noted. Nevertheless, employing high methyl violet concentrations reduced the rate and order of the reaction, with the latter becoming zero-order at such concentrations. In the case of thionine dye, the addition of copper (II) ions routinely increases the rate of reaction, and the concentration of copper (II) ions gradually decreases the order of enhancement. In contrast, the rate increased, peaked, and then declined when methyl violet was used. Furthermore, no detectable reaction happened at pH ≤ 6.0 for thionine and pH ≤ 5.0 for methyl violet; rather, the rate of reaction increased with increasing pH of the reaction media, particularly in the pH range 9.0–11.0. The interaction between two single, oppositely charged ions is indicated by the influence of ionic strength on the reaction rate. This suggests that, in the case of an uncatalyzed reaction, the hydropeorxide anion, HOO−, rather than H2O2, is the active oxidant. This also explains why the concentration of the hydropeorxide anion increases with increasing pH, leading to the rate enhancement seen. When a radical scavenger was added to the catalyzed reaction, the rate of reaction was slowed down, indicating that active free radicals were involved in the reaction process. Even at low concentrations below the threshold micelles concentration, the addition of the surfactant SDS also reduced the rate. Anionic micelles electrostatic interaction with the cationic dye may be the cause of this rate drop. The work could be used for the reuse of dye bath water to lower costs in textile and dyeing industries as well as for environmental reasons. Reaction mechanisms for both catalyzed and uncatalyzed reactions were proposed.

Abstract

Purpose
Studies evaluating inter-institutional discrepancies in muscle-invasive bladder cancer diagnosis, particularly when radical cystectomy is recommended, are scarce. In this study, we aimed to examine the inter-institutional concordance rate of pathological stages in patients diagnosed with muscle-invasive bladder cancer.
Methods
We reviewed tissue samples from patients pathologically diagnosed with muscle-invasive bladder cancer at other hospitals who subsequently sought a second opinion at our hospital between January 1, 2013 and December 31, 2023. Data were acquired retrospectively by retrieving clinical data from medical records. We investigated the inter-institutional concordance rate of pathological stages assigned to each patient and examined the tumor characteristics and prognoses of patients with pathological stage discrepancies.
Results
Of the 170 patients evaluated, 22 (12.9%) were downstaged upon pathological examination at our hospital. The tumor characteristics of stage discrepancy cases were small tumor size, solitary lesions, and vesical imaging reporting data system score < 3. Eleven patients were treated for non-muscle-invasive bladder cancer based on the re-evaluation findings. Eight patients had no evidence of disease, two patients had Ta bladder recurrence, and one patient had lung metastasis despite no bladder recurrence.
Conclusion
This study highlights the importance of pathological re-evaluation of patients diagnosed with muscle-invasive bladder cancer. The significant discrepancy rate and its impact on the treatment decisions are noteworthy. Standardization of diagnostic practices is essential to mitigate variability among pathologists and facilities and to ensure optimal care for patients with muscle-invasive bladder cancer.
Physical Restraint and Ethical Sensitivity in Intensive Care: From the Physician and Nurse Perspective
Authors: GUNES Tunay , AVCI NİLGUN 
Published: September 2024

Abstract

Introduction: The study examined the knowledge, attitudes, and practices of nurses and physicians in the intensive care unit regarding physical restraint and ethical dilemmas.
Methods: The study was conducted in four hospitals in Istanbul between February and July 2018 in a descriptive, cross-sectional, and correlational design. The sample consisted of 113 physicians and nurses. The data was collected using a personal information form, a moral sensitivity questionnaire, a nurses' knowledge level, attitudes, and practices scale regarding physical restraints, a Richmond sedation and agitation scale, and a motor activity assessment scale.
Results: 89.4% of the nurses and 78.9% of the physicians had used physical restraint before, 98.9% of the nurses and all of the physicians said that physical restraint could be applied when necessary. It was found that the mean practice score of nurses regarding the use of physical restraints (37.01±3.45) was higher than the practice score of physicians (33.57±5.38), while their knowledge and attitude scores were lower. It was determined that nurses had lower moral sensitivity than physicians due to their higher scores on the moral sensitivity questionnaire. It was found that the gender of healthcare workers and the previous use of physical restraint did not affect moral sensitivity. In contrast, the level of education and the status of working in a private hospital negatively affected moral sensitivity.
Dıscussıon: Conclusion: It was observed that the rate of physical restraint application was high in healthcare workers; moral sensitivity was affected by occupation, educational status, institution of employment, knowledge, attitudes and practices related to physical restraint.

Published: September 2024

Abstract

This study focused on a potential probiotic strain of Lactiplantibacillus pentosus (strain krglsrbmofpi2) isolated from traditional fermented rice in India. The study aimed to conduct preliminary genetic and phenotypic characterization. The strain has a genome size of 3.7 Mb, a GC content of 46%, and 3192 protein-coding sequences, as determined by genomic analysis. Subsequently, various bacteriocins, the CRISPR Cas system, phage genes, plasmids, pathogenicity, and antibiotic resistance were identified using bioinformatic methodologies. Biochemical and biophysical examinations improved our understanding of hydrophobicity, antioxidant activity, antibiotic resistance, auto-aggregation, co-aggregation properties, and tolerance to the simulated gastrointestinal condition. The safety assessment of the isolated L. pentosus was evaluated based on the hemolytic activity. The strain has demonstrated strong antibiotic activity against pathogens considered WHO priorities, such as Salmonella enterica subsp. enterica ser. Typhi, Clostridium perfringens, Escherichia coli, Listeria monocytogenes, Staphylococcus aureus, and Vibrio cholerae. Our findings suggest that gaining a deep understanding of the genetic and functional characteristics of the L. pentosus strain could pave the way for its application as a beneficial probiotic in the food industry.
Beyond the Degree: Fertility Outcomes of `First in Family' Graduates

Published: September 2024

Abstract

This paper looks at the relationship between higher education and fertility, focusing on how inter-generational educational mobility shapes this dynamic. Using the 1970 British Cohort Study, we estimate gaps in completed fertility, distinguishing between those who are the first in their family to graduate from a university (FiF), graduates with a graduate parent, and non-graduates. Our findings reveal that while on average, graduate women have fewer children than non-graduates, this difference is driven by FiF graduates. FiF women tend to have fewer children than both non-FiF graduates and non-graduates, who exhibit similar fertility rates. The fertility gap between FiF and non-FiF graduates emerges after age 35, mainly on the extensive margin: FiF women are more likely to remain childless, but those who become mothers have an equal average number of children. Similar patterns are observed among men, although the gaps are smaller and not statistically significant. We identify child-related preferences, self-esteem, and maternal employment in childhood as potential explanations behind the FiF fertility gap, while labour market outcomes, financial constraints, partnerships, and health do not appear to play a role. These findings underscore important considerations for supporting inter-generational mobility and fertility.

Published: September 2024

Abstract

Under the “Double Carbon” goal, incorporating the principles of equity, efficiency, and responsibility into the initial regional allocation of carbon emission rights is the key to promoting and optimizing China’s carbon trading market. This paper first defines the net carbon transfer responsibility between regions, then calculates the regional carbon allowance scheme based on the principles of equity and efficiency, as well as integrating principal. Our study shows that: (1) the provinces which transfer out carbon emissions are dominated by Jiangsu, Zhejiang, Shanghai and carbon trading pilot regions, while the provinces which transfer in are dominated by Shanxi, Hebei and Inner Mongolia. (2) Considering only the principle of equity will reduce the incentive for carbon emission reduction in regions with high emission reduction efficiency, such as Beijing, Shanghai and Guangdong; while considering only the principle of efficiency will exacerbate the pressure to reduce emissions in Xinjiang, Shanxi, Inner Mongolia and other high carbon emission regions. (3) Compared with equity and efficiency principle, integrated principle not only takes into account multiple factors, but also reduces the cost of carbon emission reduction among regions, which is more in line with China’s “dual-carbon” strategy.

Abstract

Coal contains a large amount of ash, resulting in coal combustion of nitrogen oxides, sulfur dioxide and other heavy metal particles have a serious impact on the ecological environment. The preparation of ultra-low ash coal has become a major means to improve the utilization rate of coal resources. Therefore, this study takes a non-stick coal as the research object. The optimum flotation process and pharmaceutical regime were explored by high-speed shear hydrophobic agglomerate flotation. The results demonstrate that non-stick coal by high-speed shear hydrophobic agglomerate flotation can reduce the ash content of the original coal by 10.5–1.49%, with a yield of up to 54.93%. In addition, the experiment also found that high-speed stirring can overcome the energy barrier of particle interaction, making the hydrophobic particles more dense, which is more conducive to effectively separating clean coal and inorganic minerals. This study provides an effective way for high value-added utilization of coal, and provides reference for realizing the fine and clean utilization of coal resources.
The effects of diatom polyunsaturated aldehydes on embryonic and larval zebrafish (Danio rerio)

Published: September 2024

Abstract

Marine diatoms are pervasive in many planktonic and benthic environments and represent an important food source for a wide range of species. Some diatoms produce polyunsaturated aldehydes (PUAs) as defensive toxins. PUA exposure is known to reduce the fecundity of invertebrate grazers like copepods and echinoderm larvae, but little is known about the effects of PUAs on vertebrates. Many fish species are likely to come into close contact with diatoms. Many may deposit eggs on diatom-coated substrates, consume diatoms as larvae, and/or feed heavily on zooplankters that may be gut-loaded with diatoms. The purpose of this study was to test whether dissolved diatom PUAs affect the early life stages of a model fish, Danio rerio (zebrafish). To test this, zebrafish embryos and larvae were exposed to proportionally increasing mixtures of the dissolved diatom PUAs 2E,4E-decadienal, 2E,4E-octadienal and 2E,4E-heptadienal. Under PUA exposure, three metrics of fitness were assessed: embryo heart rate, larval size at hatch, and pre-feeding mortality rate. Zebrafish embryos exposed at 24 hours post fertilization (hpf) experienced decreased average heart rate after 2 days of PUA exposure. Embryos 24 hpf exposed to PUA mixtures for 6 days showed a reduction in size in comparison to embryos from controls. Embryos exposed to PUAs from 2 hpf until death showed lower survivorship compared to larvae in controls. The results of this study suggest that larval fish that are sympatric with PUA producing diatoms during their embryonic and larval stages may be susceptible to detrimental effects from PUA exposure.
Adaptive Rate Compression for Distributed Video Sensing in Wireless Visual Sensor Networks
Authors: Song Zhen , Chen Jianhua 
Published: September 2024

Abstract

Distributed compressive video sensing (DCVS) for wireless visual sensor networks faces challenges due to computational limitations and bandwidth constraints. This paper presents a rate-adaptive DCVS scheme that dynamically allocates measurements based on temporal correlation and sparsity estimation. By skipping highly correlated blocks and adaptively sampling others, the proposed method achieves improved rate-distortion performance with reduced sampling complexity and transmission burden. Experimental results demonstrate substantial gains over state-of-the-art methods, especially for videos with varying motion speeds.

A implementação de políticas públicas no combate e prevenção à violência doméstica contra a mulher: uma análise no município de Vassouras/RJ
Authors: Crivas Fonseca Borges Bárbara , Rezende Gabriel Silva 
Published: September 2024

Prevista na Constituição da República Federativa do Brasil de 1988, a igualdade entre homens e mulheres em direitos e obrigações constitui um direito fundamental a ser garantido pelo Estado por meio da criação de mecanismos para coibir a violência e proteger cada um de seus membros. A ausência de marcos legais específicos instituídos pelo Estado brasileiro demonstra um descaso em relação aos compromissos estabelecidos nas Constituição, Convenções e Tratados ratificados, desta forma, o propósito deste estudo é analisar os marcos legais específicos instituídos pelo Estado e as políticas públicas na abordagem da violência doméstica no município de Vassouras, situada no estado do Rio de Janeiro. Para tanto, a metodologia utilizada foi a pesquisa qualitativa de cunho descritiva, no intuito de compreender a implementação e o suporte sociojurídico auferido pelas políticas públicas de enfrentamento à violência contra a mulher. Constatou-se que em 2020 o percentual de registros tipificados na Lei Maria da Penha atingiu o seu pico, chegando a 63,8% neste município, período em que foram implementadas novas políticas e ações de acolhimento, atendimento e orientação às mulheres vítimas, o que contribuiu para maior conscientização e análise crítica pelas vítimas, impulsionando-as a pedirem auxílio e registrarem ocorrência sobre as violências sofridas. Pode-se concluir que as políticas, apesar de recentes, têm sido efetivas quanto aos objetivos de atender, conscientizar e reduzir os casos de violência doméstica e familiar no município.
