Published: August 2024

This study aims to identify WLB in DW workers in the hospitality business during the COVID-19 pandemic in Palembang City. The hospitality business, which includes the lodging, travel and tourism, food and beverage (F&B), and recreation businesses affected by the pandemic, has changed the employment status of surviving workers to Daily Workers (DW). The reduced number of workers in this business has caused DW's workload to be heavier. Several previous studies noted that the high workload will disrupt workers' work-life balance. This study uses a causal-comparative study design to explore whether there are differences in WLB by gender and sectorally between the F&B and Lodging sectors during the pandemic. In this case, we saw WLB from the side of Time balance (TB), Involvement balance (IB), and Satisfaction balance (SB). Because the results of the normality test of the data indicate that the research data did not pass the test, We used the Mann-Whitney U Test non-parametric statistical to test the two samples in this study. Based on the test results, the WLB gender is different in the time balance variable, while from the sectoral side, WLB is different in the satisfaction balance variable.

Abstrak
Penelitian ini bertujuan untuk mengidentifikasi keseimbangan kehidupan kerja (Worklife pada pekerja harian (Daily Worker/DW) di industri perhotelan selama pandemi Covid-19 di Kota Palembang. Industri perhotelan meliputi akomodasi, perjalanan dan pariwisata, makanan dan minuman (Food and Beverage/F&B), serta rekreasi, terkena dampak pandemi yang merubah status pekerja yang masih bertahan menjadi pekerja harian. Adanya pengurangan jumlah pekerja sebagai akibat kebijakan pembatasan mobilisasi selama pandemi menyebabkan beban kerja pekerja harian menjadi lebih berat. Beberapa studi sebelumnya mencatat bahwa beban kerja yang tinggi akan mengganggu keseimbangan kehidupan dan kerja tenaga kerja. Studi ini menggunakan disain komparatif kausal untuk mengeksplorasi apakah terdapat perbedaan dalam keseimbangan kehidupan kerja berdasarkan jenis kelamin dan antar sektor, yaitu sektor F7B dan akomodasi selama pandemi. Penelitian ini, WLB akan dilihat dari sisi Keseimbangan Waktu (Time Balance/TB) Keseimbangan Keterlibatan (Involvement Balance/IB) dan Keseimbangan Kepuasan (Satisfaction Balance/SB). Oleh karena hasil pengujian normalitas menunjukkan data yang tidak terdistribusi dengan normal, analisis penelitian ini menggunakan uji statistik non-parametrik Mann-Whitney U Test. Berdasarkan hasil pengujian diketahui bahwa WLB berdasarkan jenis kelamin berbeda pada variabel keseimbangan waktu, sementara dari sisi sektoral, WLB memiliki perbedaan dalam variabel keseimbangan kepuasan.

Published: August 2024

This study seeks to ascertain whether drama has a significant impact on vocabulary instruction for young learners by looking into the teacherâ€™s teaching practice. One English instructor who frequently teaches English through drama was involved in data gathering for this study since the teacher is successful at doing so. Semi-structured interviews are the approach utilized to collect data, and Braun and Clarke's thematic analysis is then used to interpret the data (2012). Three emerging themes from this study's findings indicate the advantages of using drama to teach English: enhancing students' confidence, expanding students' vocabulary, and increasing students' interest in acquiring English language. However, based on the study's findings, the researcher concluded that young learners may benefit from drama-based vocabulary instruction for the following reasons: The use of drama in the classroom fosters intellectual and emotional conditions that promote students' ability to think. It encourages students to take chances and enables them to put their communication talents to use. Dramatic instruction increases language retention over the long run because vocabulary learning requires active participation from the learners.

The Landscape of Lawmaking
Authors: Casas Andreu , Wilkerson John D.
Published: August 2024

Lawmaking is not about enacting bills. It is about enacting policies. We portray bills as necessary vehicles for the advancement of policy ideas. To survive, a policy must be incorporated into a successful bill. But bills and policies are not the same thing. Central to our argument is the legislative hitchhiker – a policy proposal first proposed in one bill that is subsequently incorporated into another bill. Drawing on text as data methods, we demonstrate the value and feasibility of viewing lawmaking from a policy progress rather than bill progress perspective.

Capturing and releasing of hepatocellular carcinoma EpCAM+ and EpCAM- circulating tumor cells based on photosensitive intelligent nanoreactor
Authors: Mao Zhifang , Hu Meng , Shen Qinglin
Published: August 2024

Epithelial cell adhesion molecule negative circulating tumor cells (EpCAM- CTCs) and EpCAM positive CTCs (EpCAM + CTCs) have different biological characteristics. Therefore, the isolation of EpCAM + CTCs and EpCAM- CTCs is a new strategy to study the heterogeneity of tumor cells. The azobenzene group (Azo) and cyclodextrin (CD) composite system forms a photosensitive molecular switch based on the effect of external light stimulation. We used the technology of specifically capturing CTCs using anti-EpCAM and aptamers functionalized nanochips. Both anti-EpCAM and aptamers can be connected to Azo through the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide (EDC/NHS) modification process. Therefore, we assume that a photosensitive intelligent nanoreactor (PSINR) modified with anti-EpCAM can be used to capture EpCAM + CTCs; Utilizing the characteristics of aptamer and ligand binding, a PSINR modified with aptamer is used to capture EpCAM- CTCs; Then, two PSINRs were separated and stimulated with light to release EpCAM + CTCs and EpCAM- CTCs, respectively. Based on the isolation the EpCAM + CTCs and EpCAM- CTCs, we expected to reveal the key biological mechanisms of tumor recurrence, metastasis and drug resistance, and make the individualized treatment of liver cancer more targeted, safe and effective, and provide a new basis for the final realization of accurate and individualized treatment of tumors.

Purposes

The magnesium alloy bionic cannulated screw (MABCS) was designed in a previous study promoting cortical–cancellous biphasic healing of femoral neck fractures. The main purpose was to analyze the bore diameters that satisfy the torsion standards and further analyze the optimal pore and implantation direction for stabilizing femoral neck fractures.

Methods

The MABCS design with bionic holes with a screw diameter of less than 20% met the torsion standard for metal screws. The MABCS was utilized to repair the femoral neck fracture via Abaqus 6.14 software, which simulated the various stages of fracture healing to identify the optimal biomechanical environment for bionic hole size (5%, 10%, 15%, and 20%) and implantation direction (0°, 45°, 90°, and 135°).

Results

The stress distribution of the MABCS fracture fixation model is significantly improved with an implantation orientation of 90°. The MABCS with a bionic hole and a screw diameter of 10% provides optimal stress distribution compared with the bionic cannulated screw with diameters of 5%, 15%, and 20%. In addition, the cannulated screw fixation model with a 10% bionic hole size has optimal bone stress distribution and better internal fixation than the MABCS fixation models with 5%, 15%, and 20% screw diameters.

Conclusion

In summary, the MABCS with 10% screw diameter bionic holes has favorable biomechanical characteristics for stabilizing femoral neck fractures. This study provides a biomechanical foundation for further optimization of the bionic cannulated screw.
Exploring bitcoin cross-blockchain interoperability: estimation through Hurst exponent
Authors: Nan Zheng
Published: August 2024

This study aims to investigate the interoperability of the Bitcoin blockchain by comparing the US dollar prices of five cryptocurrencies derived from the Bitcoin price with their corresponding market prices. The deviation rate between the derived price and the market price, referred to as the arbitrage return rate, is examined with respect to its adherence to the efficient market hypothesis and martingale theory principles, specifically regarding mean-reversion and serial independence. Hurst exponents are estimated using R/S and DFA methods, and their dynamics are analyzed using a sliding window technique. Our findings demonstrate that the Bitcoin blockchain effectively facilitates transactions among the five cryptocurrencies, though evidence suggests a potential structural change in Bitcoin blockchain interoperability following April 2023.

Published: August 2024

Self-sovereign identity (SSI) embodies the fundamental human right to own and control a digital identity that grants access to public, social, and financial services. The absence of a dedicated digital identity layer in the development of the Internet has rendered SSI a significant challenge in contemporary society. Blockchain technology emerges as a promising solution by enabling the creation of decentralized and automatically verifiable identities. This study contextualizes SSI and analyzes how blockchain technology facilitates the autonomous management of digital identities. It explores nine prominent frameworks in this field—Sovrin, uPort, Jolocom, ShoCard, Litentry, Civic, KILT, Idena, and ION—highlighting their features, functionalities, and compliance with digital identity principles. The research concludes by identifying the challenges and opportunities in implementing these systems for digital identity management, thus contributing to the advancement of this emerging field.

Published: August 2024

Ammonia (NH₃) is a crucial industrial raw material, but the traditional Haber-Bosch process is energy-intensive and highly polluting. Electrochemical methods for synthesizing ammonia using nitric oxide (NO) as a precursor offer the advantages of operating under ambient conditions and achieving both NO reduction and resource utilization. Defect engineering enhances electrocatalytic performance by modulating electronic structures and coordination environments. In this brief review, the catalytic reaction mechanism of electrocatalytic NO reduction to NH3 is elucidated, with a focus on synthesis strategies involving vacancy defects and doping defects. From this perspective, the latest advances in various catalytic reduction systems for nitric oxide reduction reaction (NORR) are summarized and synthesized. Finally, the research prospects for NO reduction to NH₃ are discussed.
Reconceptualizing risk: toward a theory of small risks in informal family play settings

Published: August 2024

Risk-taking in early childhood play is often associated with taking physical risks in outdoor settings. In this study, we explore the notion of “small risks” as a way to examine the how parents and children engage in intergenerational play at a series of informal, indoor pop-up play events that took place at community centers in a large, urban setting. We utilize auto-photography and small stories to examine participants’ self-selected examples of the ways their family units typically engaged in play. Our findings suggest that risk-taking in play, when re-envisioned through the lens of small risks, is more complex and nuanced than previously thought, particularly for families from non-dominant communities.
Language abilities and phonological information processing mediate the association of spelling with bilingualism and socioeconomic status

Published: August 2024

Introduction

Research to date has focused on the associations between spelling and (i) its precursors (phonological information processing and language) and (ii) socioeconomic status and bilingualism. Studies have also indicated that bilingualism and parental education are associated with spelling precursors. Whereas these associations have previously been analyzed individually, this study proposes a mediation model in which the effects of socioeconomic status and bilingualism on spelling are mediated by phonological information processing and language skills.

Methods

A total of 1,012 German-speaking first graders attending primary schools in Austria were assessed at the beginning of the first grade on their phonological information processing and language abilities, and their spelling abilities were tested again at the end of the first grade. Subsequently, a structural equation modeling approach was employed to evaluate the mediation model.

Results

In line with the mediation hypothesis, the results show indirect effects of parental education (as a measure of socioeconomic status) on spelling via language and phonological information processing. In addition to mediation, we also found a direct effect of SES on spelling performances. For bilingualism, the results support full mediation as an indirect effect via language abilities. Notably, we found no effect of bilingual status on phonological information processing.

Discussion

This study highlights the ongoing need for systematic oral language training for bilingual children and children from low-SES backgrounds that starts in preschool and continues throughout primary school. Moreover, given the predictive effect of phonological awareness on spelling achievement, phonological awareness should be part of the training for preschool and school-aged children.

Published: August 2024

The evaluation of musical praxis involves a nuanced assessment of performer competencies within the intricate dynamics of musical elements, often hindered by subjective influences and the transient nature of performance. This study investigates the integration of Information and Communication Technology (ICT) tools to enhance instrumental praxis evaluation, focusing on French horn applicants to the University of Valencia Philharmonic Orchestra (OFUV). Employing a descriptive observational methodology and utilizing the MAXQDA application for analysis, the study examines key aspects of interpretation through individual recordings. Results demonstrate that ICT applications facilitate transparent and precise evaluation of performance aspects, underscoring the importance of incorporating these tools in performative education. In this regard, 89% of participants found the feedback to be very useful. Leveraging audio-video recordings offers a promising avenue for comprehensive analysis, providing clearer feedback and advocating for their integration by educational authorities and instructors to foster objective evaluation and enhance musical pedagogy.
Association between serum transferrin saturation levels and heart failure in adults aged ≥40 years: a cross-sectional study based on NHANES (2017-2020.03)
Authors: Wang Mian , Zhang Dongyang , Jiang Lanying , Ye Maosheng , Nie Jing , Yin Junjie
Published: August 2024

Background

Limited data are available regarding the association between serum transferrin saturation (TSAT) levels and heart failure (HF).

Methods

We utilized data from National Health and Nutrition Examination Survey (NHANES) 2017- 2020.03 for analysis. Data on TAST, HF and covariates were extracted and analyzed. Weighted logistic regression and subgroup analysis were used to explore the independent association between TSAT and HF. Furthermore, interaction tests were also carried out to evaluate the strata differences. We subsequently assessed whether there was a non-linear relationship between the 2 using Restricted cubic spline (RCS) and threshold effect models.

Result

A total of 282 (3.87%) participants were identified to have HF. Among the total population, participants with HF had significantly lower TSAT levels compared to those without HF (24.63 vs. 27.95, P = 0.001). After fully adjusting for potential confounders, weighted multiple logistic regression models revealed a 2.6% reduced in the risk of HF when each unit of TSAT increased. There was also a negative association between elevated TSAT and developed risk of HF in the quartile groups (Q1 OR:1.00; Q2 OR: 0.924 [95%CI:0.593,1.440]; Q3 OR: 0.515 [95%CI:0.298,0.891]; Q4 OR:0.411 [95%CI:0.201,0.839]). The subgroup analysis results remained consistent across strata, with a strong negative correlation between TSAT and HF. Interaction tests showed no dependence on gender, age, Body Mass Index, race, diabetes, hypertension, hyperlipidemia, ratio of family income to poverty and education for this negative association between TSAT and HF (all p for interaction >0.05). The RCS and threshold effect models indicated a linear negative correlation between TSAT and HF, which was more pronounced when TSAT under 40%.

Conclusion

Overall, these findings suggest a consistent and negative association between TSAT levels and the presence of HF among middle-aged and older adults in the United States.
