English is regarded as the global language in the modern period because of its broader implications for social and economic issues. For this reason, several governments are working to ensure that English is taught in order to break down barriers to communication and connection with other populations. Due to a number of issues and challenges, teaching English to adult beginners is a challenging process. Thus, the purpose of this research was to conduct a current overview of the key issues and challenges associated with teaching English to adult beginners. Using contemporary research from 2019 to 2023, the study conducted a comprehensive literature review and identified many facets of acquiring a second language. The review's conclusions clarified the main issues and challenges in teaching English to adult beginners who have no prior knowledge of the language, including a lack of confidence and the presence of anxiety, a lack of vocabulary in the language, a lack of understanding of basic English concepts, a lack of time and exposure to the language, and differences in educational backgrounds, cultures, and ethical systems.
Experimental Analysis on the Characteristics of Concrete by Incorporating Steel Slag as Partial Replacement of Sand
Authors: Yadav Sarvesh
Published: December 2023

Abstract: Steel slag is a by-product obtained in the manufacture of pig iron in the blast furnace and is produced by the blend of constituents of iron ore with limestone flux. Presently in India, owing to restricted methods of use, massive amounts of iron and steel slag are deposited in the yards of every production facility, occupying significant agricultural land, and seriously polluting the entire ecosystem. Meanwhile, the application of ecological environment protection has limited the mining of gravel, leading to a shortage of natural aggregate. Numerous studies have sought to replace natural aggregate in concrete with steel slag aggregate due to its good engineering qualities. The current research work is to investigate the concrete’s characteristics for M40-grade concrete by substitution of sand with steel slag at 10%, 20% and 30% during various curing ages. Several experiments were conducted on the characteristics of the concrete, compressive strength, and durability properties (such as water absorption and rapid chloride permeability test) up to the age of 90 days

Brand anthropomorphism and consumer brand evangelism on social networking sites: Prevention focus as a moderator
Authors: Zhang Yali , Choi Hogyu
Published: December 2023

We investigated how the use of brand anthropomorphism influences brand evangelism in social media marketing. To this end we employed two theories: regulatory focus theory and cognitive–affective personality system theory. A chain mediation model was developed to examine how brand
anthropomorphism influences consumers' brand evangelism through social presence and consumer brand identification. Additionally, we explored how prevention focus moderates this effect. In a cross-sectional experiment we obtained data from 366 respondents. The results showed that brand anthropomorphism
had a positive impact on consumer brand evangelism. Social presence and consumer brand identification mediated the relationship between brand anthropomorphism and brand evangelism. The chain mediating effect was moderated by prevention focus. When prevention focus was stronger, the chain mediating
effect between brand anthropomorphism, social presence, consumer brand identification, and consumer brand evangelism became weaker. Our findings in this study provide a reference for marketers to optimize their strategies, achieving more effective and targeted social media marketing efforts.
The negative effect of advertisement signs on consumers' willingness to purchase
Authors: Zeng Jianmin , He Ying , Ye Xing , Wang Tao , Gao Ziyun
Published: December 2023

Advertisements (ads) are intended to increase individuals' willingness to purchase and are usually expensive; thus, it would be counterproductive if an ad element actually decreased willingness to purchase. Online shopping platforms often present commodities with an advertising sign
(e. g., "ad") in the corner of their display pictures. Does this advertising sign itself increase or decrease consumers' willingness to purchase? To address this question, we conducted seven studies. Studies 1 to 5 showed that participants had less willingness to purchase, recommend, or click
on products with (vs. without) ad signs. Studies 6 and 7 revealed that participants felt the quality of products with and without ad signs was the same but they showed an implicit aversion to ads, suggesting that this unwillingness to purchase was rooted not in their explicit evaluation of
the products but in their implicit disgust at ads. Practical and theoretical implications are discussed.
Relationship between duration of commuters' job-related and leisure activities and after-work recovery: Activity quality as a moderator
Authors: Lin Yanmei , Qi Xin , Tan Lei
Published: December 2023

Commuting has been treated simply as a stressor in most studies, in the belief that it increases after-work recovery needs. In this study we took into account the role of different types of activity during commuting, and investigated the impact of time spent on these activities during
commuting on recovery. We also examined the moderating effect of the quality of the activities. The results showed that the duration of leisure activities positively influenced recovery and that the quality of the activities strengthened this positive influence. The duration of job-related
activities had a negative impact on recovery, whereas the quality of the activities weakened this negative impact. These findings show the importance of engaging in leisure activities during commuting.

Authors: Zhao Longlong , Su Peng , Yang Yuansheng
Published: December 2023

[Article Retracted] To verify the association between personality traits and academic performance in a university setting, we collected the grade point average (GPA) and six personality characteristics (honesty–humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to
experience) of 349 students at a university in China. According to the results, there were positive associations between GPA and honesty–humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience. Additionally, honesty–humility, extraversion,
agreeableness, and openness to experience explained 30.72% of the variance in GPA. On the basis of the above findings, two conclusions can be made: First, undergraduates' GPA is associated with these six personality traits; second, undergraduates' honesty–humility, extraversion, agreeableness,
and openness to experience may help to explain the variance in their GPA.

The inverted U-shaped relationship between performance appraisal interval and proactive work behavior: The dual time frame effect
Authors: Yang Jun , Ma Jun , Li Liping
Published: December 2023

In consideration of how to promote employees' work proactivity in the time frame of performance appraisals, we focused on a time-related construct called the performance appraisal interval (PAI). Drawing from psychological momentum theory, we constructed a model of the dual effect of
the PAI on employees' proactive work behavior. A cross-level analysis of 561 employees from 55 groups indicated that PAI was positively related to delayed gratification, but the effect decreased gradually as time passed. Delayed gratification was positively related to proactive work behavior
and mediated the relationship between PAI and proactive work behavior. Second, PAI was positively related to perceived uncertainty and the effect gradually increased over time. Perceived uncertainty was negatively related to proactive work behavior and mediated the relationship between PAI
and proactive work behavior. In this study we found a compatible explanatory mechanism to integrate the positive and negative effects of a given PAI, which provides a new explanatory mechanism for stimulating proactive work behavior.

Authors: Cao Fang , Jing Longjun , Liu Yang , Wang Huilin
Published: December 2023

Social interaction anxiety has become increasingly problematic among individuals who relocate to major urban areas for work, which can adversely affect their personal health and career development, leading to severe social conflicts. We used a cross-sectional survey to explore the relationship
between physical activity and social interaction anxiety, by obtaining data from 453 Beijing drifters through snowball and purposeful sampling, and used Amos 26.0 to test our hypotheses by constructing a structural equation model. Results showed that physical activity was negatively correlated
with social interaction anxiety. Additionally, interpersonal competence and perceived stress mediated this relationship. Drifters who frequently engaged in sports exhibited high levels of interpersonal competence and low perceived stress, and they were less likely to experience social interaction
anxiety than those who did not exercise. Countries and organizations should prioritize the health status of these individuals and provide more opportunities for them and other individuals to exercise.

The influence of critical thinking on creativity: A moderated mediation analysis
Authors: Long Runtian , Long Yaohong
Published: December 2023

We constructed and tested a moderated mediation model to explore the influence of critical thinking on creativity by examining the mediating role of creative self-efficacy (CSE) and the moderating role of perceived school support for creativity (PSSC) in this relationship. The sample
comprised 413 Chinese college students who completed a survey at two time points. The empirical analysis results showed that college students' critical thinking was positively related to their creativity. Further, the CSE of college students partially mediated the positive relationship between
critical thinking and creativity. In addition, PSSC positively moderated the relationships between critical thinking, CSE, and creativity, that is, when the PSSC of college students was higher, the promotion effect of critical thinking on CSE was enhanced, ultimately promoting creativity.
These conclusions enrich the relevant literature on critical thinking, CSE, PSSC, and creativity, and also provide suggestions for the higher education field on how to improve the creativity of college students.

The concept chromatography can be used to refer to a huge variety of distinct analytical procedures. Each of these procedures utilizes a mobile phase and an immobile phase as a basic component, yet they all belong under the chromatography umbrella concept. The subsequent component separation that is carried out is based on the disparity in concentration ratio that can be detected between the two phases. This disparity acts as the basis for the subsequent component separation that is carried out. Due to the limits of current technology, there is presently no detector that is universally applicable to high-performance liquid chromatography (HPLC), it is required to choose a detector in accordance with the characteristics of the chemicals that are to be examined. The measurements of absorbance in ultraviolet and visible spectrum, known as UV-Vis, or disclosing fluorescence are the foundations of the most common types of fluorescence detectors. In HPLC the components of the apparatus consist of a carrier phase, which is typically a solvent with a buffer solution; a pump; an injector; a column; a detector; and an integrator. The column is the most important part of the system where the various components are separated from one another. Based on that, there are many various kinds of columns through which the behavior of the components to be separated by these columns is understood. Due to the fact that chromatography is such a widely used technology.

Prior to the start of production, several factors must be considered, including the price, effectiveness, and environmental friendliness of batteries. Ionic liquids and deep eutectic solvents have shown significant success when employed as electrolytes with Titanium-graphite cells, especially when combined with additives that enhance their conductivity by reducing the high viscosity of these liquids. Evaluating the discharge voltage of the AlCl3-chloroacetamide IL with DCM as an additive revealed a voltage of 1.16V and an internal resistance of 11 Ohm. These electrochemical cells exhibited an intriguing response. Otherwise, when utilizing CaCl2.2H2O: Acetamide DES with DI water as an additive, the cell voltage measured 0.97V,with an internal resistance of 23 Ohm. Moreover, these cells demonstrated thermal stability during both charging and discharging processes, which can be attributed to the concentration and quality of the ionic species. Furthermore, the surfaces of the Titanium electrodes were examined using FESEM and EDXA equipment to assess the impact of the ionic liquid and DES on these electrodes.

Metformin (MEF) imprinted polymer liquid electrodes arecreated using a precipitation polymerization process. The MEF served as a template for the creation of molecularly imprinted (MIP) materials using benzoyl peroxide (BPO) as an initiator, allyl methacrylate (AMA) crosslinkers, and glycidyl methacrylate (GMA) as a monomer. UtilizingDi-octyl-phthalate (DOPH) and di-butyl phthalate (DBPH) as plasticizers in a PVC matrix, the molecularly imprinted membranes arecreated. The reaction time is approximately 50 seconds, and the limits of detection for liquid electrodes, as determined by the calibration curves, are 55.6 to 58.4 mV/decadeat 5×10-5M and 8×10-5M respectively. The liquid electrodes demonstrated good selectivity over a variety of species and a consistent reaction when filled with a typical 0.1 M drug solution across the pH range of 1 to 11. Modern electrodes can detect MEF without the need for time-consuming pre-treatment procedures in pharmaceutical samples.

n this research, we looked at how laser energy affected the structural and optical characteristics of ZrO2:ZnO thin films at mixing ratios(0.1, 0.2, 0.3and0.4) that were applied on glass slides using the pulse laser deposition technique (PLD). Nd:YAG laser was utilized with a wavelength of 1064 nm, a pulse width of 9 ns, and an energy of 320 mJ. The X-ray diffraction patterns revealed that all the films had a polycrystalline hexagonal crystal structure. AFM was used to measure the topography of the film's surface, and the results revealed that the average roughness and grain size increased. After analyzing the optical characteristics of each film, it was discovered that the absorption coefficient in the 200–1000 nm wavelength range increases at 320 mJ of laser energy and that the optical energy gap value for indirect permitted transitions decreases between 3.58 and 3.4eV

One of the most efficient metaheuristic algorithms that is used to solve hard optimization problems is the firefly algorithm (FFA). In this paper we use this algorithm to solve a single machine scheduling problem, we aim to minimize the sum of the two cost functions: the maximum tardiness and the maximum earliness. This problem (P) is NP-hard so we solve this problem using FFA as a metaheuristic algorithm. To explore the search space and get a good solution to a problem (Q), we hybridize FFA by Iterated Descent Method (IDM) in three ways and the results are FFA1, FFA2, and FFA3. In the computational test, we evaluate these algorithms (FFA, FFA1, FFA2, FFA3) compared with the genetic algorithm (GA) through a simulation process with job sizes from 10 jobs to 100 jobs. The results indicate that these modifications improve the performance of the original FFA and one of them (FFA3) gives better performance than others.

The aim of this study is to explore the relationship between work-family conflict and employee performance, as well as the effects of job satisfaction and work-family conflict on employee performance. For the study, which was conducted at PT. Kaldu Sari Nabati Indonesia Rancaekek Bandung, 195 married female employees from the Production Department were chosen. A questionnaire was used to collect the study's data, and the statistical product and service solutions (SPSS) program was used for the analysis. The results demonstrate that although work-family conflict does not directly and significantly affect employee performance, it does so when job satisfaction is taken into account as a mediator. Furthermore, employee performance is significantly positively impacted by job satisfaction. These results highlight the crucial role that job satisfaction plays in minimizing the detrimental effects of work-family conflict on employee performance.

This study explores the impact of brand experience, service quality, customer satisfaction, and trust on customer loyalty within the mobile telecommunications sector in Batam City. The participants of this research were residents of Batam who utilized cellular telecommunications services. Data was collected through an online questionnaire via Google Forms, targeting 300 respondents who were customers of mobile telecommunications services. The data analysis revealed several key findings: 1. A significant positive relationship exists between brand experience and customer loyalty. 2. Service quality is strongly linked to customer satisfaction. 3. There is a notable connection between brand experience and customer trust. 4. Customer satisfaction significantly influences customer loyalty.5. Service quality indirectly affects customer loyalty through customer satisfaction. 6. Interestingly, the study found no direct significant relationship between trust and loyalty, nor between brand experience and loyalty when mediated by trust. These results suggest that while brand experience, trust, and customer satisfaction are important factors influencing loyalty, trust does not directly contribute to building customer loyalty, nor does brand experience impact loyalty through trust. Moreover, maintaining high service quality is emphasized as a fundamental requirement for telecommunications service providers. This research provides valuable insights into the dynamics of customer loyalty in the mobile telecommunications context, offering practical implications for businesses in this industry aiming to enhance their customer retention strategies.

Published: December 2023

This study aims to analyze the impact of the implementation of online ticket booking applications on the number of train passengers based on ticket sales data. The development of technology has brought significant changes in the transportation industry, including trains, with the introduction of online ticket booking applications. The analysis method used is a non-parametric statistical test to measure the relationship between the application and the number of passengers. Train ticket sales data for several years before and after the implementation of the application were used in the analysis. The results of the analysis showed a positive relationship between the implementation of online ticket booking applications and an increase in the number of train passengers. The findings support the view that the ease of access and convenience in booking tickets through the app has encouraged more people to use rail services. Although the results of this study indicate the positive impact of implementing online ticket booking applications, there are several other factors that can affect the number of passengers, such as economic factors, promotions, and additional services offered by train operators. Therefore, this study has limitations in considering all these factors. Based on these findings, it is recommended that train operators continue to develop and improve online ticket booking applications as part of their marketing and customer service strategies. This research contributes to understanding how technology can shape consumer behavior in the transportation industry and the extent of its impact on train passenger numbers.

Good corporate governance and profitability are efforts to increase company value. The company was established to increase the company value to provide prosperity for the owners or shareholders. This study aims to determine the effect of corporate governance on company value with profitability as an intervening variable in manufacturing industries in manufacturing companies. The data research is taken from the financial reports of 19 selected companies on the Indonesia Stock Exchange for 2015-2020 using quantitative research. The independent variables are proxied by institutional ownership, audit committee, managerial ownership, independent Board of Commissioners, and Board of Director. Return on equity is a proxy of the profitability as an intervening variable and Tobin's q as a dependent variable. The method of data analysis used in this research is multiple linear regression analysis using statistical software. The data results show that the independent Board of commissioners and directors significantly influences ROE. The other three variables are not significant in predicting ROE. The audit committee and independent panel of commissioners do not affect the company's value.

On the other hand, company value is affected by institutional ownership, managerial ownership, and the Board of directors. Those five variables of good corporate governance and ROE simultaneously effectively predict company value with a 75.17% contribution. Profitability mediates the relation between good corporate governance and company value.
