Abstract
Purpose
The accuracy of the machining process is significantly impacted by the performance of hydrostatic bearings. This paper aims to analyze the influence of micro-textured on the performance of the hydrostatic bearing, and the performance of the bearing is improved by designing the arrangement of micro-textured.
Design/methodology/approach
Different designs have been used while creating micro-textured bearings. The finite element models of bearing with smooth and micro-textured were established and solved using the computational fluid dynamics method. The arrangement scheme of the micro-textured was evaluated by comparing the influence of the distribution position and arrangement of the micro-textured on the bearing performance.
Findings
To improve the performance of the bearing, the bearing capacity was significantly increased, and the friction coefficient of the bearing was decreased when the micro-textured was distributed in the form of an obtuse angle arrangement in the maximum pressure area of the bearing. The experimental findings validate the analysis method.
Originality/value
In this paper, the effect of irregularly arranged micro-textured on bearing performance is investigated to improve the bearing capacity and lubrication status.

Abstract
Purpose
Of critical concern to the world is the need to reduce consumption and waste of natural resources. This study provides a multi-level exploration of the ways situational and transformational links between levels and challenges are related to the adoption and utilization of material flow cost accounting in Vietnam, to encourage green productivity.
Design/methodology/approach
Based on triangulation of public documents at different institutional levels and a set of semi-structured interviews, situational and transformational links and challenges for material flow cost accounting in Vietnam are examined using purposive and snowball sampling of key actors.
Findings
Using a multi-level framework the research identifies six situational and transformational barriers to implementation of material flow cost accounting and suggests opportunities to overcome these. The weakest links identified involve macro-to meso-situational and micro-to macro-transformational links. The paper highlights the dominance of meso-level institutions and lack of focus on micro transformation to cut waste and enable improvements in green productivity.
Practical implications
The paper identifies ways for companies in Vietnam to reduce unsustainability and enable transformation towards sustainable management and waste reduction.
Originality/value
The paper is the first to develop and use a multi-level/multi-time period framework to examine the take-up of material flow cost accounting to encourage transformation towards green productivity. Consideration of the Vietnamese case builds understanding of the challenges for achieving United Nations Sustainable Development Goal number 12, to help enable sustainable production and consumption patterns.

Abstract
Purpose
Proponents of micro-credentials envision them as vehicles for upskilling or re-skilling individuals. The study examines how integrating micro-credentials in the higher education ecosystem enhances employability. It aims to offer insights from the perspective of stakeholders who may benefit from these credentials at an institutional or individual level.
Design/methodology/approach
Online in-depth interviews are conducted with 65 participants from India, Nigeria, the United Arab Emirates and the United Kingdom to explore how micro-credentials can be a valuable addition to the higher education ecosystem. A multi-stakeholder approach is adopted to collect data.
Findings
The analysis highlights two possible methods of integrating micro-credentials into the higher education ecosystem. First, micro-credentials-driven courses can be offered using a blended approach that provides a flexible learning path. Second, there is also the possibility of wide-scale integration of micro-credentials as an outcome of standalone online programs. However, the effectiveness of such programs is driven by enablers like student profiles, standardization and the dynamics of the labor market. Finally, the study stipulates that micro-credentials can enhance employability.
Originality/value
The study's findings suggest that, for successful integration of micro-credentials, an operational understanding of micro-credentials, their enablers and strategic deliberation are critical in higher education. Institutions must identify the determinants, address technological limitations and select a suitable delivery mode to accelerate integration. However, micro-credentials can augment employability, considering the increasing emphasis on lifelong learning. An overview of the findings is presented through a comprehensive framework.

Abstract
Purpose
Micro-regeneration can effectively enhance a neighborhood’s commercial vitality and serve as a viable approach to boost economic benefits. However, the small scale of micro-regeneration efforts and the fragmented nature of information currently limit the availability of strong empirical evidence demonstrating its impact on neighborhood commercial vitality. The aim of the study was to examine the link between micro-regeneration and neighborhood commercial vitality, focusing on the average, time-lag, spatial spillover, and spatial heterogeneity effects.
Design/methodology/approach
Using the panel data set of 1,755 neighborhoods in Chongqing from 2016 to 2021 as the research sample, the difference-in-differences (DID) method was employed in this study to explore the impact micro-regeneration has on neighborhood commercial vitality.
Findings
The results illustrate that: (1) micro-regeneration can promote neighborhood commercial vitality in terms of the number and types of local consumption amenities by 27.76 and 5.89%, respectively, with no time-lag effect; (2) the positive spillovers can exist within the range of 5,000 meters–5,500 meters of regenerated neighborhoods; and (3) the effect of micro-regeneration on neighborhood commercial vitality can be greater in peripheral areas than in core areas of the city.
Originality/value
The findings fill the knowledge gap on the relationship between micro-regeneration and neighborhood commercial vitality. Additionally, the results on the time-lag effect, spatial spillover effects, and spatial heterogeneity provide practical implications that can support the government and private sector in developing temporal and spatial arrangements for micro-regeneration projects.

Abstract
Purpose
This study examined the factors impeding the implementation of micro-credentials and accepting it as a credible source of earning professional qualifications and certifications necessary for pursuing higher education or other career goals.
Design/methodology/approach
The factors were identified by reflecting on the recent literature and Internet resources coupled with in-depth brainstorming with experts in the field of micro-credentials including educators, learners and employers. Two ranking methods, namely Preference Ranking for Organization Method for Enrichment Evaluation (PROMETHEE) and multi-objective optimization based on ratio analysis (MOORA), are used together to rank the major challenges.
Findings
The results of this study present that lack of clear definitions, ambiguous course descriptions, lack of accreditation and quality assurance, unclear remuneration policies, lack of coordination between learning hours and learning outcomes, the inadequate volume of learning, and lack of acceptance by individuals and organizations are the top-ranked and the most significant barriers in the implementation of micro-credentials.
Research limitations/implications
The findings can be used by educational institutions, organizations and policymakers to better understand the issues and develop strategies to address them, making micro-credentials a more recognized form of education and qualifications.
Originality/value
The novelty of this study is to identify the primary factors influencing the implementation of micro-credentials from the educators', students' and employers' perspectives and to prioritize those using ranking methods such as PROMETHEE and MOORA.

Abstract
The focus of this chapter is on micro-credentials in higher education. In the current complex and fluid context, there is a demand for higher education providers to be able to respond with flexible and targeted provision of learning opportunities. Crafting micro-credentials, or disaggregating credentials, can be effective in reaching target audiences. For students, the availability of micro-credentials allows them to satisfy immediate learning needs. For industry, micro-credentials can provide elements of vocational training. On the other hand, it is a challenge to design micro-credentials that provide the cognitive perspective associated with higher education to ensure an appreciation of an associated body of knowledge or field of study. Further, education offered by universities and other higher education providers needs to have the potential to support the ongoing academic life of the institution, which is dependent on teaching being informed by research and current understandings in the field, and the research area being refreshed with talent with an appreciation of their field of study and associated bodies of knowledge. This, therefore, can be seen as something of an eco-system, which is dependent for its sustenance on learners acquiring more than fragments of knowledge or information. There are consequences for devising policies and procedures for the design, recognition, and provision of micro-credentials in higher education. Policies and procedures need to explicitly relate micro-credentials to the current and emerging understandings in an academic discipline or field of study. Academic standards that apply to offering credentials need to be maintained. Associated staff support and development is a requirement.

Abstract
At the centre of Chapter 2 is higher education that places greater emphasis on lifelong learning journeys and equitable access to quality education at all stages of an individual's life and career. This chapter articulates the relevance of learning outcomes for both the world of work and for citizenship in a global and interconnected world. One way to operationalize this dual emphasis is through micro-credentials, which offer a flexible and modular way to learn new skills and knowledge. The chapter notes current challenges with implementing micro-credentials in a robust and quality assured manner, and suggests ways to overcome these.
Mentoring is a valuable support system for academics wishing to implement micro-credentials and contribute to the achievement of all sustainable development goals. Mentors can help nurture initial ideas, guide the design and delivery of micro-credentials and ensure that they are aligned with the needs of students and university external stakeholders. The dialogue included in this chapter illustrates a specific scenario at undergraduate level. There is, however, recognition that a broader range of contexts for micro-credentials exists, where mentoring can provide equally valuable support towards achieving desired goals.
With specific reference to mentoring, the chapter discusses ways in which mentoring relationships can develop and be maintained over time. It considers the impact that the setting in which mentoring meetings take place can have on the quality of the learning experience. Equally importantly, discussion touches on digital dimensions of mentoring – the metaverse as a setting and artificial intelligence complementing a real mentor or coach.

Abstract
Purpose
Digitalisation is reshaping the learning process, shifting it towards personalisation and online learning, and fuelling the growth of massive open online courses (MOOCs) and micro-credentials. Despite being a popular global trend, limited studies have looked at micro-credentials and their impact on learners' behavioural outcomes. The purpose of this study is to investigate the impact of programme design factors on learning experience, as well as the inter-relationships between programme design, learning experience and behavioural responses (e.g. engagement and willingness to pay more (WTPM)) towards micro-credentials. In addition, the study aims to investigate learning enjoyment as a moderator.
Design/methodology/approach
A survey questionnaire was used to collect data from 354 respondents who are working adults living in the major economic states in Malaysia. Data analysis was performed using the analysis of a moment structures (AMOS) statistical software and SPSS (Statistical Package for the Social Sciences) PROCESS macro.
Findings
The results show the significance of programme design factors (i.e., flexibility, system quality and content quality) in determining the learning experience. The learning experience is found as a mediator in the relationship between programme design factors and learner engagement and WTPM. In addition, the moderation assessment confirms that enjoyment during learning strengthens the relationship between experience and behavioural responses.
Originality/value
This study is amongst a few selected studies that focus on engagement in and WTPM for micro-credentials. In addition, it emphasises the mediating role of the learning experience and the moderating role of enjoyment in understanding the impact of programme design on learners' experiences and behavioural responses.

Abstract
Purpose
The purpose of this study is to analyse potential models of Islamic crowdfunding as an alternative financing option for micro-entrepreneurs in Malaysia. While crowdfunding has gained traction as an alternative funding source for businesses, it is unclear how far this concept can benefit a group of micro-entrepreneurs in Malaysia.
Design/methodology/approach
This study uses a qualitative research approach by using data collected through semi-structured interviews with several experts and practitioners in crowdfunding, Shariah and entrepreneurship. Prior to discussing the facets of the findings, the data were analysed based on a thematic approach.
Findings
The findings reveal that while previous works of related literature suggest crowdfunding as a viable alternative financing option for entrepreneurs and their businesses, in reality, its practical implementation presents challenges. Numerous micro-entrepreneurs need more training in the areas of management and marketing. Such concerns raise questions about their ability to attract potential project backers. With the proper selection of Shariah contracts and several approaches to risk management, Islamic crowdfunding can potentially become an alternative funding source for microbusinesses.
Research limitations/implications
Given the exploratory nature of this study regarding the applicability of Islamic crowdfunding as an alternative fund for micro-entrepreneurs, its findings may not fully encompass Malaysia’s context because of the limited number of participants involved.
Practical implications
The findings of this study offer guidelines on how to implement Islamic crowdfunding for micro-entrepreneurs. Consequently, Islamic crowdfunding has the potential to alleviate the government’s burden of providing funds for micro-enterprises and enhance their skills and mentality to be more independent, creative and able to promote their products.
Social implications
While Islamic crowdfunding can be an alternative opportunity for business enterprises and community-based projects, it promotes the spirit of cooperation and collaboration within society.
Originality/value
Although Islamic crowdfunding is a topic that has been discussed previously, empirical investigations in this area remain scarce, mainly through qualitative approaches. Distinguishing from prior literature, this study analyses several potential models of Islamic crowdfunding from the perspectives of experts, practitioners and related agencies for micro-entrepreneurs. Moreover, this study bridges insights from related literature so that they offer practical applications to support micro-entrepreneurs in Malaysia.

Abstract
Purpose
It was verified that the micro-texture in the front and back of the tool at the same time had a positive effect on improving the milling behavior and surface quality of the tool. The purpose of this study is to explore the rationality of simultaneous placement of micro-textures on the front and rear surfaces of ball-end milling cutters, analyze the influence of micro-texture parameters on tool milling behavior and workpiece surface quality, reveal its internal mechanism, and obtain the best micro-texture parameters by optimization.
Design/methodology/approach
First, the mechanism of micro-texture is studied based on the energy loss model. Second, the orthogonal experiment is designed to analyze the influence of micro-texture parameters on tool milling behavior and reveal its mechanism by combining simulation technology and cutting experiment. Finally, the parameters are optimized based on the artificial bee colony algorithm.
Findings
The results show that the simultaneous placement of micro-texture on the rake face and flank face of the tool has a positive effect on improving the milling behavior and surface quality of the tool. Taking milling force, tool wear and surface roughness as the evaluation criteria, the optimal parameter combination is obtained: the rake face micro-texture diameter is 50 µm, the distance from the micro-texture is 200 µm and the distance from the cutting edge is 110 µm; the diameter of the micro-textured flank is 40 µm, the distance from the micro-texture is 170 µm and the distance from the cutting edge is 130 µm.
Originality/value
Taking milling force, tool wear and surface roughness as the evaluation criteria, the optimal parameter combination is obtained: the rake face micro-texture diameter is 50 µm, the distance from the micro-texture is 200 µm and the distance from the cutting edge is 110 µm; the diameter of the micro-textured flank is 40 µm, the distance from the micro-texture is 170 µm and the distance from the cutting edge is 130 µm, which provides theoretical support for the further study of the micro-textured tool.
