The purpose of this study is to solve the problems of poor stability and high energy consumption of the dynamic window algorithm (DWA) for the mobile robots, a novel enhanced dynamic window algorithm is proposed in this paper.

The novel algorithm takes the distance function as the weight of the target-oriented coefficient, and a new evaluation function is presented to optimize the azimuth angle.

The jitter of the mobile robot caused by the drastic change of angular velocity is reduced when the robot is closer to the target point. The simulation results show that the proposed algorithm effectively optimizes the stability of the mobile robot during operation with lower angular velocity dispersion and less energy consumption, but with a slightly higher running time than DWA.

A novel enhanced dynamic window algorithm is proposed and verified. According to the experimental result, the proposed algorithm can reduce the energy consumption of the robot and improves the efficiency of the robot.

Considering that low-level general trust may hinder communication, this study aims to detect the factors that can influence general trust between exhibitors and visitors during business-to-business trade fairs.

Based on a literature review and stakeholders’ behavior analysis, a conceptual model of general trust formation between exhibitors and visitors is proposed.

The preconditions of strangers’ general trust patterns mainly include their early experience regarding trust, institutional trust in the environment and trust propensity. Stakeholders’ treatment, trust transfer, on-site restraints, reward and punishment expansion and on-site personnel arrangement may facilitate the formation of general trust between exhibitors and visitors.

This paper is a conceptual article that requires further investigation to verify the main factors that influence general trust and the impact of general trust on other trust components between exhibitors and visitors.

Organizers, exhibitors and visitors should pay attention to participants’ selection, supervision, self-discipline and personnel management before and during trade fairs. International and small-scale, especially new trade fairs in developed and developing countries, must consider additional measures to improve general trust.

The existing literature has not focused on general trust in the trade fair context. In this paper, research on network and relationship marketing is further deepened in terms of a specific trust type. The interactions between stakeholders before and during fair may promote general trust among participants than in other settings, which partially explains why trade fair (even other two-sided markets) can increase social capital.

Strategic management relies on an array of complex methods to understand how firms can attain and sustain competitive advantage. How researchers employ different methods to conduct their research in different research contexts and understand the implications associated with their research choices is fundamental to the methodological rigour and the advancement of strategic management theory.

The study examined users' perceived level of service at the African Union Court on Human and Peoples' Rights (AUCHPR) library in Arusha, Tanzania.

The study adopted a quantitative approach in line with the tenets of the LibQUAL and SERVQUAL protocols, which were used as theoretical lenses and informed the development of questionnaires which were used to collect data. The target population consisted of 94 library users.

The study found that the library's best services, in terms of their quality and as perceived by users, lie in its human resources (i.e. affect of service, assurance and responsiveness). On the other hand, the lowest perceived level of services was recorded in the aspects related to information collection and physical facilities (i.e. library as a place and tangibles).

This study was based on the African Court on Human and Peoples' Rights library in Arusha, Tanzania. The study covered both internal and external users of the library.

The study identified strengths and weaknesses of the African Court library as far as the perceived level of service is concerned, and the findings can therefore be used to inform decisions on the improvement of quality of the library services. In so doing, the library will be in a stronger position to offer quality services and assist the court in attaining its objectives of promoting and protecting human rights in Africa. With improved library service quality, the non-judicial staff, external users and society in general will stand to benefit from the library.

While drawing lessons from previous service quality studies, this study is the first quality assessment study to be done in the African Court library. It is also the first to use a combination of LibQUAL and SERVQUAL models in the context of the African Court library services.

Three-dimensional (3D) printing, one of the important technological pillars of Industry 4.0, is changing the landscape of future manufacturing. However, the limited build volume of a commercially available 3D printer is one inherent constraint, which holds its acceptability by the manufacturing business leaders. This paper aims to address the issue by presenting a novel classification of the possible ways by which 3D-printed parts can be joined or welded to achieve a bigger-sized component.

A two-step literature review is performed. The first section deals with the past and present research studies related to adhesive bonding, mechanical interlocking, fastening and big area additive manufacturing of 3D printed thermoplastics. In the second section, the literature searches were focused on retrieving details related to the welding of 3D printed parts, specifically related to friction stir welding, friction (spin) welding, microwave and ultrasonic welding.

The key findings of this review study comprise the present up-to-date research developments, pros, cons, critical challenges and the future research directions related to each of the joining/welding techniques. After reading this study, a better understanding of how and which joining/welding technique to be applied to obtain a bigger volume 3D printed component will be acquired.

The study provides a realistic approach for the joining of 3D printed parts made by the fused deposition modeling (FDM) technique.

This is the first literature review related to joining or welding of FDM-3D printed parts helping the 3D printing fraternity and researchers, thus increasing the acceptability of low-cost FDM printers by the manufacturing business leaders.

The purpose of this paper is to investigate the direct and indirect influences of workplace environment factors on the motivation to transfer the acquired training (MT) and the transfer of training. The workplace environment factors under study encompass the organizational support, supervisor support, peer support, technological support and the opportunity to use the acquired training.

In the study, the empirical data were garnered from a sample of 220 business school students, using a 52-question questionnaire. A research framework was first proposed and the structural equation modeling subsequently utilized to test the research framework and determine the direct influence of the workplace environment factors on the transfer of training and also their indirect influence on TT through the MT variable.

The structural equation modeling model is congruent with the empirical data, with the χ² statistic of 24.414, the degree of freedom of 21, the p-value of 0.273, the goodness of fit index of 0.977 and the root mean square error of approximation of 0.027. The findings revealed that the workplace environment factors directly influenced the training transfer behavior of the participants and indirectly through the MT of the individuals. Most importantly, the proposed model could achieve the coefficient of prediction (R²) as high as 82 percent.

Workplace environment is important to motivation to transfer and transfer of training. To enhance the training transfer effectiveness, businesses should take into account the contributions associated with each environment factor in the design and implementation of training programs.

Despite the enormous investment in employee training, training effectiveness is often hampered by insufficient transfer of learning (TOL) among trainees, making the return on training investment suboptimal. The challenge of effective TOL among employees is enormous, including personal and organizational factors, and research exploring this is inconclusive. This study aims to investigate organizational climate and TOL and the mediating role of emotional intelligence.

Applying identical elements and social cognitive theories, the study used multistage sampling techniques through purposive, convenience and simple random sampling collected using validated measures of the study constructs formed into a survey questionnaire. Multiple Regression and Process Macro were used to analyze the data.

Results revealed significant relationships between formalization, performance feedback, employee participation, innovation and flexibility with TOL. Organizational climate dimensions jointly and independently predicted TOL. However, only formalization was inversely related to TOL. Emotional intelligence partially mediates the relationship between organizational climate dimensions and TOL. The study recommends the need for managers to encourage autonomy, creativity and flexibility and provide honest and valid feedback to foster the TOL.

By addressing the limitations of other studies, this study advances knowledge by underlining the significance of including and further exploring the mediating role of trainees’ emotional intelligence on the relationship between organizational climate (formalization, performance feedback, employee participation, innovation and flexibility) and TOL.

This study aims to understand the epistemic foundation of the classification applied in the first Chinese library catalogue, the Seven Epitomes (Qilue).

Originating from a theoretical stance that situates knowledge organization in its social context, the study applies a multifaceted framework pertaining to five categories of textual data: the Seven Epitomes; biographical information about the classificationist Liu Xin; and the relevant intellectual, political, and technological history.

The study discovers seven principles contributing to the epistemic foundation of the catalogue's classification: the Han imperial library collection imposed as the literary warrant; government functions considered for structuring texts; classicist morality determining the main classificatory structure; knowledge perceived and organized as a unity; objects, rather than subjects, of concern affecting categories at the main class level; correlative thinking connecting all text categories to a supreme knowledge embodied by the Six Classics; and classicist moral values resulting in both vertical and horizontal hierarchies among categories as well as texts.

A major limitation of the study is its focus on the main classes, with limited attention to subclasses. Future research can extend the analysis to examine subclasses of the same scheme. Findings from these studies may lead to a comparison between the epistemic approach in the target classification and the analytic one common in today's bibliographic classification.

The study is the first to examine in depth the epistemic foundation of traditional Chinese bibliographic classification, anchoring the classification in its appropriate social and historical context.
