The mediating role of perception of decent work in role clarity and job embeddedness among Chinese nurses: A cross-sectional study
Authors: Chen Fang , Yu Ran , Zheng Huan , Zhao Xiaoyan 
Published: October 2024

Abstract

Aim
To explore the relationship among clinical nurses' perception of decent work, role clarity, and job embeddedness, and to analyze the mediating effect of perception of decent work on role clarity and job embeddedness, and provide reference for improving nurses' job embeddedness level.
Background
The high turnover rate of the nursing team is not only detrimental to maintaining the stability of the team, but also to providing high-quality nursing services, which is an immeasurable loss for both patients and hospitals. As a predictor variable of turnover rate, increasing the level of job embeddedness among nurses can reduce their willingness to resign. Although there are currently studies reporting the correlation between role clarity, perception of decent work and job embeddedness, the mechanisms between the three have not been explored, which cannot provide scientific and effective theoretical support for developing targeted measures for job embeddedness.
Methods
Using convenience sampling method, 309 nurses from hospitals in Zhejiang Province China were recruited as the research subjects from July to August 2024. The General Information Questionnaire, Decent Work Perception Scale, Role Clarity Scale and Job Embeddedness Scale were used for the investigation.
Results
This study shows that the perception of decent work, role clarity, job embeddedness are all at a moderate level. The total score of job embeddedness is positively correlated with the total scores of perceived decent work and role clarity, and the perception of decent work plays a partial mediating effect between role clarity and job embeddedness, accounting for 88.1% of the total effect.
Conclusions and Implications for Nursing and Health
Policy:
According to the results of this study, to improve the job embeddedness level of clinical nurses, the hospital nursing department and head nurses in the department should explore different measures to stimulate the perception level of decent work of clinical nurses and improve their role clarity cognition, to enhance their job embeddedness level.

Abstract

In the present paper we report upon the influence of heavy doping of thin Si layers with Sb on the carrier transport in the temperature range 2 < T < 300 K and magnetic field induction (B) up to 9 T. Temperature and magnetic field dependencies of the longitudinal (ρxx(T,B)/σxx(T,B)) and transversal Hall (ρxy(T,B)/σxy(T,B)) components of tensor resistivity/conductivity were measured in the samples prepared by epitaxial technology and containing Sb atoms with densities near the concentration of Mott transition 1.05×1024 ≤NSb ≤ 4.0×1024 m-3. The use of normal contributions to ρxx(T,B)/σxx(T,B) and ρxy(T,B)/σxy(T,B) made it possible to estimate the concentrations and mobilities of charge carriers (electrons) depending on Sb content NSb, concentrations of localized surface states (LSS) 1×1018 ≤NS ≤5.6×1019 m-2 and disorder parameter 1 ≤ kFl ≤ 60 of Si layers, where kF and l being the wave vector and the mean free path of electrons, respectively. It was found that the relative longitudinal MRxx(T,B) = Δρxx(T,B)/ρxx(T,0) and the transversal MRxу(T,B) = Δρxу(T,B)/ρxy(T,0) magnetoresistive effects were significantly dependent both on the type of samples (NSb below or beyond the Mott transition) and on the presence/absence of LSS in them (for locked samples with the lowest NS covered with undoped Si layer or unlocked samples with the highest NS, respectively). In unlocked (with a great content of LSS) semiconductor-type samples, the values of MRxx(T,B) and MRxу(T,B) were positive at all temperatures (which is mainly due to the Lorentzian motion of electrons in a magnetic field). In the locked semiconductor type sample and in the unlocked metal-like sample, MRxx(T,B) and MRxу(T,B) became negative either in the entire region 2 < T < 30 K (locked) or only below 7 K (unlocked) . In this case, the normal longitudinal component of the conductivity tensor in zero and non-zero magnetic field included contributions from quantum corrections to Drude carrier transport (interference and the effect of electron-electron interaction and spin-dependent contributions with times of wave functions phase breaking of electrons tφ of the order of 2 - 100 picoseconds and coherent lengths (Thouless lengths) of ~ 20 - 400 nm) and the anomalous one including different types of spin-dependent effects (due to spin-orbit and spin-spin interactions, as well as intrinsic or asymmetric skew scatterings of free electron spins on paramagnetic Sb ions).

Published: October 2024

Abstract

Introduction:The neighborhood is a regular living and activity space for the elderly. It is important to identify neighborhood environmental factors that can alleviate depression in the elderly to improve their health. However, existing literature does not consider the complex interdependencies among key neighborhood environmental factors.
Method:This study employs the Qualitative Comparative Analysis (QCA) method to explore how the configuration of neighborhood environmental conditions can help alleviate depressive symptoms in the elderly. The data is derived from the 2020 China Family Panel Study (CFPS) survey.
Results: The results show that three different neighborhood environment configurations can help reduce depressive symptoms in older Chinese individuals. The first configuration requires a combination of neighborhood safety, good neighborhood relations, and neighborhood assistance. The second configuration involves amalgamating optimal community facilities, high-quality neighborhood relations, and neighborhood assistance. The third configuration encompasses sound community facilities, favorable housing surroundings, a secure communal atmosphere, and advanced neighborhood assistance. Furthermore, we identify neighborhood assistance as a core condition for alleviating depressive symptoms and find that the combined effects of neighborhood safety and housing surroundings on alleviating depressive symptoms are comparable to the effect of neighborhood relationships.
Discussion:These research results deepen the current understanding of neighborhood environment configurations to alleviate depressive symptoms in older adults, offer important implications for theory and practice, and set new directions for the construction of age-friendly neighborhoods.

Published: October 2024

Abstract

Lateritic nickel deposits frequently contain elevated concentrations of chromium. The recovery of this fraction of the chromium resource can enhance the comprehensive utilization of resources, while simultaneously reducing the energy consumption and environmental pollution associated with smelting. The objective of this study was to investigate the feasibility and technical challenges associated with the recovery of chromium from lateritic nickel deposits from a mineralogical perspective. To this end, a process mineralogical study was conducted on a lateritic nickel deposit in Indonesia. It was discovered that chromium often occurs as chromium mineral like chromite and exhibits significant physical differences from common minerals in lateritic nickel deposits, such as limonite and serpentine, making it suitable for physical beneficiation. Consequently, the recovery rate and feasibility of chromium recovery can be predicted on the basis of determining the granularity and liberation characteristics of chromite and the occurrence state of the chromium element. This will enable a more scientific approach to be taken to the physical beneficiation process.

Abstract

Background: Psoriasis is a psychocutaneous disorder whose prognosis is affected by psychological factors. Despite the psychological impact of the disease only 33% of the sufferers receive mental healthcare. The current study was planned to estimate the prevalence and factors affecting psychiatric co-morbidities among psoriasis patients in a tertiary care hospital.
Materials and methods: 288 consecutive patients diagnosed with psoriasis of the age 18 and above were inducted in the study. Patient were included after signing informed consent. Patient particulars were noted in the sociodemographic profile sheet and clinical profile sheet designed for the study. Diagnosis of psychiatric disorders was made according to ICD-10. If the patients are found to have anxiety or depressive disorders, the severity of the same was assessed by using appropriate scales.
Result: Anxiety was reported in 66 (22.9%) patients. Mild depression found in 23 (8.0%) patients, moderate depression occurred in 25 (8.7%) patients, and severe depression recorded in 23 (8.0%) patients. Psychiatric comorbidity was present in 74.3%, with maximum patients being diagnosed with anxiety disorder unspecified. The association between psychiatric comorbidity and higher educational level, living in joint families, in urban areas and lower middle socioeconomic status was statistically significant.
Conclusion: Our study showed the psychiatric burden to be significant in patients with psoriasis. It represents an unmet need with treatment of psychiatric comorbidity leading to improved quality of life.

Abstract

Recent prolonged summer seasons have posed significant challenges for mushroom cultivation, underscoring the need for summer-adapted commercial varieties like Calocybe indica. Casing plays a crucial role in its cultivation, which traditionally uses loamy soil (LS). However, given the non-renewable nature of LS and the environmental concerns associated with spent mushroom substrate (SMS), our study explored SMS as a potential alternative. We examined the physio-chemical properties, and microbial flora especially bacterial composition using MALDI-TOF in both LS and SMS, along with the total yield, biological efficiency, mineral content, and total phenolic and flavonoid contents of mushrooms grown on these substrates. While most of the physio-chemical properties of SMS align with the ideal casing properties, it exhibits higher electrical conductivity (EC) and a greater C/N ratio. The dominating bacterial flora in SMS, including Bacillus, Priestia,and Lysinbacillus, contribute to the mushrooms’ temperature tolerance and facilitate nutrient uptake especially phosphorous (P). The yields and biological efficiency were significantly higher in LS, likely due to its superior mechanical support. Furthermore, the results found that element levels, especially copper (Cu), zinc (Zn), and phosphorous (P), were significantly higher in mushrooms grown on SMS except iron (Fe). Notably, phosphorus (P) levels were significantly elevated in mushrooms grown in SMS, highlighting the role of phosphorous-solubilizing bacteria in SMS. The PCA biplot results further supported these findings. Interestingly, Calocybe indica consistently exhibited higher iron (Fe) content than Pleurotus ostreatus, regardless of the casing material used. The metal bioaccumulation factors (BCF) reveal that Calocybe indica is a hyperaccumulator of potassium (K) but does not bioaccumulate manganese (Mn). It also showed a low calcium (Ca) and iron (Fe) accumulation level, suggesting a synergistic interaction between Ca and Fe. No significant difference in total phenolic and flavonoid content was observed between the LS and SMS. In conclusion, LS proved more effective in maximizing yield, while SMS emerged as a sustainable alternative with the enhanced nutritional quality of mushrooms, making it a viable option for environmentally conscious mushroom cultivation.

Published: October 2024

Abstract

With the advent of Web 3.0, the swift advancement of technology confronts an imminent threat from quantum computing. Security protocols safeguarding the integrity of Web 2.0 and Web 3.0 are growing more susceptible to both quantum attacks and sophisticated classical threats. The article introduces our novel long-distance free-space quantum secure direct communication (LF QSDC) as a method to safeguard against security breaches in both quantum and classical contexts. Differing from techniques like quantum key distribution (QKD), LF QSDC surpasses constraints by facilitating encrypted data transmission sans key exchanges, thus diminishing the inherent weaknesses of key-based systems. The distinctiveness of this attribute, coupled with its quantum mechanics base, protects against quantum computer assaults and advanced non-quantum dangers, harmonizing seamlessly with the untrustworthy tenets of the Web 3.0 age. The focus of our study is the technical design and incorporation of LF QSDC into web 3.0 network infrastructures, highlighting its efficacy for extended-range communication. LF QSDC is based on the memory DL04 protocol and enhanced with our novel Quantum-Aware Low-Density Parity Check (LDPC), Pointing, Acquisition, and Tracking (PAT) technologies, and Atmospheric Quantum Correction Algorithm (AQCA). Utilizing this method not only bolsters the security of worldwide Web 3.0 networks but also guarantees their endurance in a time when quantum and sophisticated classical threats exist simultaneously. Consequently, LF QSDC stands out as a robust security solution, well-suited for Web 3.0 systems amidst the constantly evolving digital environment.

Published: October 2024

Abstract

Background
HIV prevention actions have always attributed the responsibility to the individual to decide to use condoms, which has been shown to be inefficient, in addition to promoting prejudice against the most vulnerable populations. This study aimed to identify, through verbal reports, the factors that influence condom use.
Methods
A total of 120 MSM were interviewed (60 without infection - G1 and 60 living with HIV - G2), users of the Domingos Alves Meira Specialized Infectious Diseases Outpatient Clinic in Botucatu, through invitations on social networks and the “snowball” technique. Data was collected using a questionnaire prepared by the researcher herself. To analyze the data, the frequencies and percentages of responses were calculated, as well as a comparison between the groups (G1 and G2) using the chi-square test. The theoretical analysis of the results was based on the concepts of self-knowledge and self-control.)
Results
Of the 120 MSM, with or without HIV infection, who were studied, 79.2% reported having had passive anal sex in the last six months and 75.0% had not used a condom with all partners. The reasons for not using condoms were trusting the partner, being more focused on the pleasure of the moment, and having only oral sex.
Conclusions
Suggestions are that the low frequency of safe sexual practices is more related to contingencies maintained by the group than to individual weaknesses or failures, highlighting the need for a better understanding of the social contexts in which these individuals find themselves.

Abstract

Volatile organic compounds resulting from metabolic processes are released as biogas, and potentially can serve as noninvasive biomarkers of cellular metabolic health. During ferroptosis, a form of cell death caused by lipid peroxidation (LPO), oxidized lipid fragments can be released as biogas. We identified ω-6 PUFA-derived volatile oxidized lipids (VOLs) produced and released by cells undergoing metal-dependent LPO. Among several identified VOLs, 1-octen-3-ol and 2-pentylfuran, were validated as ferroptosis markers in in vitro cultured cells, in vivo animal models, and in human breath. We find these VOLs specifically produced in the liver during ferroptosis, in model mice of metabolic dysfunction-associated steatohepatitis (MASH) and in the exhaled air from patients with MASH. Our identification of specific VOLs released upon metal-dependent LPO, highlights their potential utilization as valuable markers for cells undergoing ferroptosis in vivo, which can be apply non-invasively to monitoring cellular health in humans.

Published: October 2024

Abstract

This paper presents a comprehensive analysis of the (1 + 1)-dimensional Klein–Gordan equation which plays a significant role in various areas of theoretical and applied physics. The main focus of this research centers on several key areas. First, infinitesimal generators of symmetries were found by Lie symmetry invariance analysis. Then, using the adjoint representation, an ideal system was created based on the found Lie vectors. Secondly, by utilizing the analytical approach, namely the modified Sardar sub equation (MSSE) method, we systematically derive various novel soliton solution in the form of dark, bright, periodic, singular, combo, hyperbolic as well as mixed trigonometric. Finally, bifurcation analysis is performed at the system’s fixed points, revealing chaotic behavior when an external force is introduced into the dynamic system. To identify the chaotic characteristics, a range of tools, such as 3D and 2D phase plots, time series, Lyapunov exponents, and multistability analysis, are utilized. Additionally, the sensitivity analysis of the model is examined under different initial conditions. These results enhance the understanding of nonlinear wave phenomena in mathematical physics and hold potential applications across numerous scientific disciplines.
Conservation genetics of Mahogany Gliders and insights into their evolutionary relationship with Squirrel Gliders

Published: October 2024

Abstract

Squirrel Gliders (Petaurus norfolcensis) are widely distributed throughout the woodlands of eastern Australia, while the similar but larger Mahogany Glider (Petaurus gracilis) inhabits the coastal woodlands of the Wet Tropics in northeastern Queensland. The Mahogany Glider is an Endangered species due to habitat loss and fragmentation. To inform effective conservation management, this study used single nucleotide polymorphism markers (SNPs) from field and museum-derived samples to investigate genetic relationships within the Squirrel/Mahogany Glider complex and conduct a conservation genetics assessment for the Mahogany Glider. Analyses of genetic structure, phylogenomics, and outlier loci identified four genetic groups: Mahogany Glider and three distinct groups in Squirrel Gliders (North Queensland, Cape Cleveland, and mid-eastern/south-eastern Queensland). We found genetic admixture between these groups, but whether the admixture is historic or current remains unclear. Gliders from North Queensland were genetically more similar to Mahogany Gliders in some analyses than to the other Squirrel Glider groups. Morphological analysis confirmed that Mahogany Gliders are distinguishable from other gliders by their larger body size and longer tail. The study emphasizes the taxonomic uncertainty in the Mahogany-Squirrel Glider complex and the need to investigate glider populations at contact zones. When assessing Mahogany Gliders alone, we found a clear north-south split in genetic structuring, with the southern cluster being more structured than the northern cluster. Genetic diversity within Mahogany Gliders was generally comparable to that of Squirrel Gliders, but some sampling localities indicated loss of genetic diversity and low effective population size. Regardless of whether Mahogany Gliders are classified as a species or subspecies, their Endangered status underscores the need for targeted conservation efforts. The genetic findings offer practical pathways for on-ground management to enhance population recovery and connectivity.

Abstract

Background: The availability of essential medicines (EMs) is an important aspect of quality healthcare services. This study aimed to assess the availability, stock-out periods, record-keeping, presence of expired medicines, and conservation and handling of selected EMs across different levels of Government Healthcare Institutions (GHCIs) in Monaragala, one of the rural districts in Sri Lanka.
Methods: A descriptive, cross-sectional study was conducted, with retrospective data collection methods where necessary. Six GHCIs representing four different levels of care were selected in Monaragala District, Sri Lanka. EMs for 23 diseases were selected from the National Essential Medicine List (EML) of Sri Lanka. Data was collected using survey forms adapted from the WHO operational package for assessing, monitoring, and evaluating country pharmaceutical situations (WHO-OP). Ethics review approval was obtained from the Ethics Review Committee, the Open University of Sri Lanka, and institutional permissions were obtained from the relevant authorities.
Results: The average availability of selected EMs was fairly high (77.1%) in the Monaragala district, while the “highest” availability (80.49%) was recorded by divisional hospitals type B. The highest average stock-out days (66 days) were reported from the Divisional Hospital- Type C. Only Divisional Hospital- Type A reported having expired medicines on shelves (2.43%). All six GHCIs reported more than 80.49% for record-keeping on medicines. Divisional Hospital Type-A reported having the lowest score for warehouse management.
Conclusions: The availability of EMs at the GHCIs of the Monaragala district was fairly high. Record keeping of EMs was high while the average number of stock-out days varied per institution. Conservation and handling practices of the store rooms and dispensing areas of the GHCIs in the Monaragala district should be further improved.
