This study examines the link between ethical leadership and innovative work behavior. Also, drawing on the substitute for leadership theory, this study investigates the role of a follower's proactive personality in the relationship between ethical leadership and innovative work behavior (IWB). Similarly, this study further explores the role of psychological safety in this relationship.

The data for this study were collected from software development companies based in Islamabad, Pakistan. A total of 240 employees and their immediate supervisors were asked to participate in this study. Processes Macro and Amos were used to assess study hypotheses.

Using data from software companies in Pakistan, this study found that ethical leadership can be effective to enhance IWB in followers whose proactive personality is low, while this effect is limited in high proactive individuals. Furthermore, psychological safety mediates the main effect of ethical leadership on IWB as well as the interactive effect between ethical leadership and follower's proactive personality on IWB.

This study is among the first to investigate the moderating role of employees' proactive personality in the relationship between ethical leadership and followers' IWB. Secondly, draws on the substitute for leadership perspective, this study explains that how the role of ethical leadership can be less effective for high proactive individuals or how individual characteristics can substitute leadership behavior. Thirdly, this study deepens our understanding of the mechanisms linking ethical leadership to IWB by exploring the role of psychological safety as a mediator. Finally, our research is based on data collected from Pakistan might also add some new insights to the existing west-dominated literature.

The purpose of this paper is to examine the nature of relationship between ethical leadership and employee voice behavior. Study of employee voice behavior is important, because leaders in organizations make numerous decisions based on employees’ work-related inputs which do influence the decision quality and team performance.

Survey data were collected through structured questionnaire from Indian organizations. Data were analysed through statistical techniques such as confirmatory factor analysis and structural equation modeling.

The findings showed that ethical leadership did impact the employee voice in a positive and significant but moderate manner. The study also found no significant differences in ethical leadership and voice behavior across demographic variables such as gender, age, educational qualification and job level in the Indian context.

The study is conducted using single cross-sectional research design, and for better causal inferences of the relationship between various variables, future research studies may be conducted with longitudinal research design, multiple data sources and variety of industries with large sample size.

With erosion of ethical values and corporate scandals, managers need to develop and display ethical leadership as employees emulate their leaders’ ethical behavior because ethical leadership, or its perception, relates positively and significantly to employee voice behavior.

There is less study to understand ethical leadership and its influence on voice behavior in developing countries, especially in India. Ethical leadership behavior encourages employees to voice their work-related constructive opinions and concerns for improved decision-making and reduced unethical practices. Also, there is scarcity of research that explores the impact of demographic variables and this study is an effort to understand this gap.

This paper aims to test the effects of social presence (SP) and other related factors, including trust, self-construal and brand familiarity, in affecting consumers’ purchase intention of live-streaming workout courses.

Three between-subjects, Web-based experimental studies were conducted. There were separately 108, 208 and 284 valid questionnaires collected in the three studies. Moderation and mediation analyses were performed to test the research hypotheses.

Users’ sense of SP when watching live-streaming courses positively affects their willingness to purchase courses, and users’ sense of trust plays a mediating role in the influence of users’ SP on their purchase intention. In addition, when users belong to dependent self-construal rather than independent self-construal, their trust in live-streaming courses plays a stronger mediating role in the influence of users’ SP on their purchase intentions. What is more, when users have high brand familiarity rather than low brand familiarity, their trust in online live-streaming plays a stronger mediating role in the influence of users’ SP on their purchase intentions.

This research delineates the effects of SP on the consumption of live-streaming courses, thus further adding to the understanding of the role of real-time interaction in determining consumer behavior. It also highlights the roles of self-construal and brand familiarity as mediating influences on the relationship between SP and consumer trust.

The marketisation of higher education fosters the notion of students as consumers, highlighting the shifting dynamics of student–teacher relationships. This paper aims to contribute to ongoing discussions about students as consumers and their involvement in pedagogical practices. We explore students’ experiences in short-term study abroad (SA) programmes that involve collaborative learning, examining how a consumerism-oriented approach affects students’ perceptions of their pedagogical identities and student–teacher pedagogical relationships.

A qualitative exploratory study was conducted to capture students’ rich and subjective perceptions and experiences. The data were gathered through semi-structured interviews with 15 Chinese undergraduate students who participated in a short-term SA programme at a UK university. Following data translation and transcription, a thematic analysis approach facilitated our exploration.

Chinese students engage in SA programmes as a strategic investment in personal growth and transformation, with their consumer-oriented identity fostering a mutually beneficial relationship with educators and group members. This consumer mindset appears to enhance active student engagement and, to some extent, create reciprocal student–teacher interactions through power sharing and collaborative involvement.

This study presents empirical data exploring the impact of consumer identity on the dynamics of student–teacher relationships in the SA context. It provides recommendations for implementing pedagogical approaches designed to mediate the influence of consumerism on student engagement, particularly in shaping collaborative student–teacher relationships. This study offers insights for future research on the effects of consumerism in higher education within cross-cultural contexts.

Developing a sense of belonging among immigrant youth in multicultural contexts has attracted significant attention from scholars during the last few decades. Studies have already underscored how various educational factors hinder or facilitate students’ sense of belonging to the school or the larger society. Although most students in Hong Kong schools are ethnic Chinese, a significant number of non-Chinese children make students diversity an essential aspect of schooling. The study investigated how schools can develop a sense of belonging among ethnic minority youth in Hong Kong.

As the education system in Hong Kong lacks a multicultural education policy, how can schools help develop a sense of belonging to the school and the larger society among young ethnic minority people? To answer this question, this paper consolidates the two sets of data originally gathered for two research projects. The data was collected through semi-structured in-depth interviews with nine secondary school teachers (Chinese and non-Chinese) and 15 students (non-Chinese) and analysed thematically.

The thematic analysis of the qualitative data identified several challenges and opportunities for developing ethnic minority students’ sense of belonging in Hong Kong.

Researchers in comparative education can further explore how multicultural education and inclusive education approach together can help ensure inclusive and equitable quality education for all and cater to students' diverse learning needs across the education systems.

Given that the aims of multicultural education and inclusive education resonate with each other, schools can focus on the Whole School Approach to developing a sense of belonging among ethnic minority youth in Hong Kong. However, policymakers and practitioners may need to adopt a multifaceted perspective on inclusive education that strives to ensure equitable quality education for all.

The study contributes to the existing body of scholarship on multicultural education and inclusive education. The study findings underscore the importance of an interdisciplinary research framework in education and advocate an integrative approach to supporting students with diverse learning needs in multicultural contexts.

This paper aims to investigate a novel impact time control guidance (ITCG) law based on the sliding mode control (SMC) for a nonmaneuvering target using the predicted interception point (PIP).

To intercept the target with the minimal miss distance and desired impact time, an estimation of time-to-go is introduced. This estimation results in a precise impact time for multimissiles salvo attack the target at the same time. Even for a large lead angle, the desired impact time is achieved by using the sliding mode and Lyapunov stability theory. The singularity issue of the proposed impact time guidance laws is also analyzed to achieve an arbitrary lead angle with the desired impact time.

Numerical scenarios with desired impact time are presented to illustrate the performance of the proposed ITCG law. Comparison with the state-of-art impact time guidance laws proves that the guidance law in this paper can enable the missile to intercept the target with minimal miss distance and final impact time error. This method enables multiple missiles to attack the target simultaneously with different distances and arbitrary lead angles.

An ITCG law based on sliding mode and Lyapunov stability theory is proposed, and the switching surface is designed based on a novel estimation time-to-go for the missile to intercept the target with minimal miss distance. To intercept the target with initial arbitrary lead angles and desired impact time, the authors analysis the singular issue in SMC to ensure that the missile can intercept the target with arbitrary lead angle. The proposed approach for a nonmaneuvering target using the PIP has simple forms, and therefore, they have the superiority of being implemented easily.

Recently, electric vehicles have been widely used in the cold chain logistics sector to reduce the effects of excessive energy consumption and to support environmental friendliness. Considering the limited battery capacity of electric vehicles, it is vital to optimize battery charging during the distribution process.

This study establishes an electric vehicle routing model for cold chain logistics with charging stations, which will integrate multiple distribution centers to achieve sustainable logistics. The suggested optimization model aimed at minimizing the overall cost of cold chain logistics, which incorporates fixed, damage, refrigeration, penalty, queuing, energy and carbon emission costs. In addition, the proposed model takes into accounts factors such as time-varying speed, time-varying electricity price, energy consumption and queuing at the charging station. In the proposed model, a hybrid crow search algorithm (CSA), which combines opposition-based learning (OBL) and taboo search (TS), is developed for optimization purposes. To evaluate the model, algorithms and model experiments are conducted based on a real case in Chongqing, China.

The result of algorithm experiments illustrate that hybrid CSA is effective in terms of both solution quality and speed compared to genetic algorithm (GA) and particle swarm optimization (PSO). In addition, the model experiments highlight the benefits of joint distribution over individual distribution in reducing costs and carbon emissions.

The optimization model of cold chain logistics routes based on electric vehicles provides a reference for managers to develop distribution plans, which contributes to the development of sustainable logistics.

In prior studies, many scholars have conducted related research on the subject of cold chain logistics vehicle routing problems and electric vehicle routing problems separately, but few have merged the above two subjects. In response, this study innovatively designs an electric vehicle routing model for cold chain logistics with consideration of time-varying speeds, time-varying electricity prices, energy consumption and queues at charging stations to make it consistent with the real world.

This study aims to solve the problems of ambiguous localization, large calculation, poor real-time and limited applicability of bolt thread defect detection.

First, the acquired ultrasound image is used to acquire the larger area of the image, which is set as the compliant threaded area. Second, based on the determined coordinates of the center point in each selected region, the set of coordinates on the left and right sides of the bolts is acquired by DBSCAN method with parameters eps and MinPts, which is determined by data set dimension D and the k-distance curve. Finally, the defect detection boundary line fitting is completed using the acquired coordinate set, and the relationship between the distance from each detection point to the curve and d, which is obtained from the measurement of the standard bolt sample with known thread defect, is used to locate the bolt thread defect simultaneously.

In this paper, the bolt thread defect detection method with ultrasonic image is proposed; meanwhile, the ultrasonic image acquisition system is designed to complete the real-time localization of bolt thread defects.

The detection results show that the method can effectively detect bolt thread defects and locate the bolt thread defect location with wide applicability, small calculation and good real-time performance.

The type 120 emergency valve is an essential braking component of railway freight trains, but corresponding diaphragms consisting of natural rubber (NR) and chloroprene rubber (CR) exhibit insufficient aging resistance and low-temperature resistance, respectively. In order to develop type 120 emergency valve rubber diaphragms with long-life and high-performance, low-temperatureresistant CR and NR were processed.

The physical properties of the low-temperature-resistant CR and NR were tested by low-temperature stretching, dynamic mechanical analysis, differential scanning calorimetry and thermogravimetric analysis. Single-valve and single-vehicle tests of type 120 emergency valves were carried out for emergency diaphragms consisting of NR and CR.

The low-temperature-resistant CR and NR exhibited excellent physical properties. The elasticity and low-temperature resistance of NR were superior to those of CR, whereas the mechanical properties of the two rubbers were similar in the temperature range of 0 °C–150 °C. The NR and CR emergency diaphragms met the requirements of the single-valve test. In the low-temperature single-vehicle test, only the low-temperature sensitivity test of the NR emergency diaphragm met the requirements.

The innovation of this study is that it provides valuable data and experience for future development of type 120 valve rubber diaphragms.

This study explores the characteristics of female space evolution in Korean vernacular houses in the Yanbian region of China. In addition, it discusses the influence of social logic on the evolution of female spaces.

This study utilises space syntax methodology to examine the evolution of female spaces in Korean vernacular houses in terms of connectivity value, step depth and integration value. Furthermore, it conducts an analytical exploration of social logic based on the evolutionary characteristics of female space.

The findings elucidate the evolutionary characteristics of the spatial configuration of female spaces in Korean vernacular houses, with differential changes in connectivity, a gradual tendency towards openness and simplicity and increased accessibility and centrality. This reflects the changing spatial needs of Korean women brought about by changes in lifestyle, consciousness, social status and family structure.

This study provides perspectives and insights into the vernacular architecture and architectural sociology of ethnic minorities in regions of China and Asia. Furthermore, it can provide relevant construction organisations with a more intuitive understanding of Korean vernacular houses and a reference for future house renewal and construction in the Yanbian region.

Although many studies have investigated various aspects of Korean vernacular houses and female spaces, none have examined the influence of social logical changes on the evolution of female spaces in Korean vernacular houses. Thus, this study is valuable and novel.
