Abstract

This paper introduces a new subject called bio‐manufacturing. Bio‐manufacturing combines life science with manufacturing science, and uses manufacturing method to form materials with bio‐activity and bio‐degradability into scaffolds. In this paper, we discuss the hierarchy of bio‐manufacturing: the lower grade uses undegradable bio‐material to form permanent organ replacement such as auricular cartilage and the higher grade uses biodegradable bio‐materials to repair organ damage or organ replacement which degrades after embedded in the human body. They all adopt jetting/extrusion deposition process (fused deposition modelling or 3D printer), the distinct different point being the temperature of the forming chamber. The samples of bones and auricular cartilage produced by those processes had been practiced on dogs and rabbits, repaired their damage.

Abstract

Multi‐functional rapid prototyping manufacturing system (M‐RPMS) is an important potential developing field and tendency of RP technique. Application area of the M‐RPMS has been discussed in this paper. It is believed that the M‐RPMS has to be developed both for industrial and academic purposes. The openness of software and hardware, the diversity of RP processes and the highest function/cost ratio are the outstanding speciality of the M‐RPMS. This paper also introduces the design principle of the M‐RPMS, the calculation method for function integration degree (FID), the running of SLS in the M‐RPMS and the key of early stage rapid feedback design system.

Abstract

Purpose

In plastic reconstruction surgeries, total auricular reconstruction for microtia is a real challenge. Presently, autogenous costal cartilage and MEDPOR are the chosen materials but none can satisfy the requirements of orthopaedic operation. The purpose of this paper is to examine how to fabricate an ear scaffold with a good shape.

Design/methodology/approach

A new approach to form the auricle framework is described. CT scan data of the patient's contralateral “good ear” are used to generate a 3D reconstruction model of the new ear. This model is then imported into rapid prototyping (RP) software to slice. The sliced data drive the fused deposition modeling (FDM) machine to build the ear framework layer by layer. Based on the actual shape of the computer model, FDM technology produces a real feel ear framework to match the size of the opposite good ear.

Findings

An artificial human ear was built using FDM technology based on CT images. The auricular framework with polyurethane was a porous structure with good flexibility and biocompatibility. After implanting into the mouse, a real life human ear appeared on the back of the mouse. The experiment indicated that this method provided an efficient way to macrotia reconstruction.

Originality/value

The freeform fabrication technique combined with CT image reconstruction could provide an efficient way to produce a porous structure and solve the framework carving problem in microtia reconstruction.

Abstract

Purpose

This study examines the effects of incentive compensation and guanxi, a type of informal personal relationship between people, on the objectivity of Chinese internal auditors. Given that the objectivity of internal auditors is essential for promoting financial reporting quality, it is important to investigate the effectiveness of internal audit functions, especially in emerging markets where the corporate governance mechanisms designed to promote objectivity are less mature.

Methodology/Approach

The research employs a 2 × 2 between participants experiment with 116 graduate accounting student participants.

Findings

After controlling for internal auditors’ ethicality, we find that close-guanxi between management and internal auditors and incentive compensation in the form of bonuses based upon meeting earnings targets both have the capacity to impair the objectivity of Chinese internal auditors. Participants were more tolerant of management’s attempts to manage earnings when there was close guanxi or bonus compensation. Further, compensation structure only influenced internal auditors’ support of management when guanxi was distant, but when there was close guanxi between internal auditors and management, internal auditors were unlikely to challenge management regardless of the compensation structure.

Abstract

Purpose

This paper aims to fast predict vibration responses of specific locations in the satellite subject to acoustic environment. It proposes a set of vibro-acoustic simulation methods of satellite components to represent their conditions in the whole satellite during the ground tests or launching. This study aims to use vibro-acoustic models of satellite components to replace that of hard modeling and time-consuming whole satellite when only local responses are concerned.

Design/methodology/approach

This paper adopted experimental and numerical studies, with the latter based on the finite element (FE), statistical energy analysis (SEA) and FE-SEA hybrid theories. The vibro-acoustic model of the whole satellite was built and verified by experimental data. Based on the whole satellite model and experimental results, the fast vibro-acoustic simulation methods of all kinds of typical satellite components were discussed.

Findings

This paper shows that the models about satellite components not only show high consistency but also reduce 61.6% to 99.8% times compared with the whole satellite model. The recommended fast simulation methods for all kinds of typical satellite components were given in comprehensive consideration of the model accuracy, time required and response accessibility.

Originality/value

This paper fulfils an identified need to perform fast vibro-acoustic prediction of the local positions in satellites.

Abstract

Purpose

The online healthcare platform (OHP) has become an essential element of the healthcare system, representing a technological shift in the job responsibilities of medical professionals. Drawing on a technology-based job demands–resources (JD-R) model, this study aims to examine how the technological characteristics of OHP affect doctors’ OHP use psychology and behavior.

Design/methodology/approach

This empirical study was based on a survey conducted among 423 doctors with OHP use experience. The proposed model underwent assessment through partial least squares structural equation modeling (PLS-SEM) to reveal the effects of technology-based job demands (i.e. technology-based work overload and technology-based work monitoring) and resources (i.e. perceived usefulness, facilitating conditions and IT mindfulness) on doctors’ OHP fatigue and continuance use intention.

Findings

Results suggest that technology-based work monitoring, perceived usefulness and facilitation conditions have significant impacts on doctors’ psychological and behavioral responses to using OHP, whereas technology-based work overload and IT mindfulness have a single impact on continuance use intention and fatigue of OHP.

Research limitations/implications

It assists doctors, healthcare administrators, policymakers and technology developers in understanding OHPs’ technological characteristics, enabling them to harness its benefits and mitigate potential challenges. Additionally, given the self-reported cross-sectional data from China, future studies can improve generalizability and adopt experimental methods or longitudinal designs with objective data.

Originality/value

It extends the research on OHP by employing a technology-based JD-R model to explore work attributes and dual effects associated with OHP’s technological characteristics. It also enriches existing research by examining the role of OHP’s technological characteristics in doctors’ psychological and behavioral responses.

Abstract

Purpose

Since the limited growth of enterprises has been identified as a deliberate choice of women entrepreneurs, the purpose of this paper is to illustrate how the institutional environment of an entrepreneurial ecosystem (EE) fosters the gender gap in entrepreneurial growth intention. The mediating role of the perceived institutional environment in the gender effect on entrepreneurial growth intention is tested in the Chinese context. As individuals’ cognitions are usually influenced by their cultural orientations, the gender difference in perceptions of the institutional environment is considered to be contingent on entrepreneurs’ self-construal.

Design/methodology/approach

Using a multiregional sample of 206 Chinese entrepreneurs who completed the questionnaire, the study obtained results by adopting a structural equation modelling analysis with a partial least squares approach.

Findings

There are significant gender gaps in perceptions of the institutional environment and growth intention among Chinese entrepreneurs. Due to their limited political ties and lower legitimacy in economic activities in the country, Chinese women entrepreneurs have more negative perceptions of the regulative and cognitive institutional environment than their male counterparts, which accounts for the lack of growth ambition among Chinese women entrepreneurs. Independent self-construal enlarges the difference in environmental perceptions between male and female entrepreneurs.

Originality/value

This research enriches the discussion in the emerging area of EEs by adequately responding to the highlighted target to advance ambitious entrepreneurship and offering an interpretation of its evolutionary thinking. Given the increasing calls for a focus on high-growth women’s entrepreneurship, this study provides an explanation for how the institutional environment engenders the absence of women in growth-oriented entrepreneurial activities. It also uncovers the overlooked deficiency in institutional practice by highlighting the gender inequality in the implementation process of entrepreneurial support policies and the distribution of entrepreneurial capabilities in society.

Abstract

Purpose

This paper examines the ways in which Chinese university middle managers evaluate subordinate performance in response to the Chinese Double First-Class University Plan, a national project that ranks the performance of universities. In exploring compromise arrangements, the hybridised valuing activity of middle managers is found to be shaped by emergent and extant macro-foundations.

Design/methodology/approach

The qualitative data from 49 semi-structured interviews at five Chinese public universities were conducted. Drawing on macro-foundational studies and the sociology of worth (SW) theory, the analysis helps to identify socially shared patterns of actions and outcomes.

Findings

The findings elucidate the interplay between diverse economic, social, political and institutional values and the compromise-making by middle managers. The authors find that contextual factors restrict Chinese academic middle managers' autonomy, preventing workable compromise. Through the selective adoption of international and local management practices, compromise has evolved into a private differential treaty at the operational level.

Originality/value

A nuanced explanation reveals how the macro-foundations of Chinese society influence middle managers who engage with accounting when facilitating compromise. This study helps outsiders better understand the complex convergence and divergence of performance evaluative practices in Chinese universities against the backdrop of global market-based forces and the moral dimensions of organisational life. The findings have wider implications for the Chinese government in navigating institutional steps and developing supportive policies to enable middle managers to advance productive but also sustainable compromise.

Abstract

Purpose

The purpose of this paper is to explore two dimensions of leadership practices (i.e. teaching and learning and sources of power) used by two exemplary principals in mainland China against a background of education reform and to identify how broader contextual factors have shaped these two dimensions of their leadership.

Design/methodology/approach

An exploratory case study was used that drew upon semi‐structured interviews, observations and document analysis. Interviews were conducted with two principals, six teachers from each of the two schools and a superintendent who was the supervisor of the two principals.

Findings

The findings reveal that there are some common elements in both of the leaders' practices but also some subtle differences. Both leaders emphasise teaching and learning. One sees herself as curriculum expert; the other delegate teaching responsibilities. While both uses a top down approach, one principal uses an adversarial approach and the other a more facilitative approach.

Research limitations/implications

The study used a small sample size. It explored the leaders' practices in the light of broader contextual factors rather than personal factors or gender‐based factors

Originality/value

Given the limited empirical research conducted on female principals in mainland China, this qualitative study provides insights into two dimensions of leadership used by two exemplary principals and explains their practices in the light of critical contextual factors such as contemporary and traditional Chinese culture and the school's organisational context.
