Abstract
Purpose
This paper aims to explore the feasibility of rapid prototyping for human hand bones and additional artery with topological preservation.
Design/methodology/approach
A serial of slices derived from spiral computed tomography human hand specimen was imported into 3DSlicer 4.4.0 to obtain a three-dimensional virtual model. The model is exported as a standard template library file. Additional arteries were structured according to the atlas and the bone model. Then, a real model was printed based on the virtual model. Measurements were approached in 11 parts of the virtual and real model.
Findings
There is no statistical difference between virtual and real model in 11 parts, and the topological characters were preserved.
Practical implications
This method can be used in reconstruction of clinical iconological blood vessel and anatomical education.
Originality/value
This paper shows that it is possible to keep the topological structure of blood vessel not only in painting but also in clinical data.

Abstract
Purpose
The purpose of this paper is to analyze the effect of the reputation of underwriters and sponsoring representatives on initial public offering (IPO) underwriting fees, and further investigates the role of ownership and political connection.
Design/methodology/approach
The methodology includes three models. Model 1 empirically investigates the effect of underwriter’s reputation on underwriting fee. Model 2 studies the effect of sponsoring representative’s reputation on underwriting fee. Model 3 further examines the effect of underwriter’s reputation and sponsoring representative reputation on the underwriting fee controlling for the impact of ultimate controlling ownership and political connection.
Findings
The study documents that underwriters’ and sponsoring representatives’ reputation can result in reputational premiums. In the IPO of state-owned enterprises (SOEs), the reputation of underwriters and sponsoring representatives does not significantly affect the underwriting fees. In the IPO of non-state-owned enterprises (NSOEs), there is a significantly positive correlation between underwriters’ and sponsoring representatives’ reputation and underwriting fees. Further research results show that, on the one hand, the effect of underwriters’ and sponsoring representatives’ reputation on underwriting fees is not significant in the IPO of NSOEs with political connection. On the other hand, underwriting fees are positively associated with underwriters’ and sponsoring representatives’ reputation in the IPO of NSOEs without political connection.
Research limitations/implications
The sponsoring representative’s fee is not disclosed separately, which makes it difficult to distinguish the incremental effect from underwriter’s services and reputation.
Practical implications
NSOEs relative to SOEs are more likely to pay higher underwriting fees for hiring underwriter and sponsoring representative with better reputation during the process of IPO.
Social implications
The reputation of underwriter and sponsoring representative does not matter to SOEs but does matter to NSOEs. However, NSOEs’ political connection affects underwriter fees.
Originality/value
This paper provides new evidence of sponsoring representatives’ reputation and political connection on the underwriting fees in the IPO in Chinese SOEs and NSOEs.

Abstract
We develop our theoretical framework from the viewpoint of the information asymmetry and the agency theory that the Chinese mutual funds exhibit herd behaviour, and provide empirical evidence by using cross-sectional data of all the Chinese mutual funds between 1999 and 2003. We find that the Chinese mutual funds show overall herding, buy herding and sell herding, and the degree of sell herding is higher than that of buy herding. The degree of Chinese herding is higher than their US counterpart from all the three perspectives. This may be largely due to the institutional factors rather than those firm-specific factors that influence the US mutual funds investment decision.

Abstract
This study provides evidence that Chinese initial public offerings (IPOs) report better operating performance than industry peers in the pre-IPO period, and worse performance in post-IPO period compared to the pre-IPO level. We find that related party transactions (RPTs) with controlling shareholders have significant effects on the long-run performance of IPO firms. Controlling shareholders structure a large percentage of operating (non-loan) RPTs to artificially boost revenues and/or profits of their IPO subsidiaries in the pre-IPO period. However, in the post-IPO period, controlling shareholders discontinue this RPT-based earnings manipulation practice and begin to expropriate IPO subsidiaries by obtaining a large percentage of cash loans, primarily in return for profits and/or resources transferred into the IPO subsidiaries in the pre-IPO period. Finally, we find that state-controlled IPO firms with a highly concentrated ownership structure and a less independent board of directors are more likely to be expropriated by controlling shareholders in the post-IPO period through related loans.

Abstract
Purpose
In today’s Taiwan, sha-cha sauce is an indispensable ingredient for beef hot pot and stir-fried dishes. The purpose of this paper contextualizes the history of sha-cha sauce in Tainan, the oldest city in Taiwan, and argues that sha-cha sauce, introduced by Chaoshan immigrants, has contributed to new styles and habits of beef consumption tastes and habits in the post-1949 Tainan and beyond.
Design/methodology/approach
This paper uses documentary materials, oral interviews and diaries to explore the relationship between beef consumption and sha-cha sauce. It begins with an historical overview of Taiwan’s beef consumption during the Japanese colonial era (1895-1945). Then, it focuses on two Chaoshan business enterprises: the Bull-Head, which makes the world’s largest “canned sha-cha sauce,” and the Xiao Haozhou, a Tainan restaurant specializing in sha-cha beef hot pot. Finally, this study analyzes Xinrong Wu, a Tainan gentry whose diary entries from 1933 to 1967 documented the changing dietary habits of beef consumption among Taiwanese.
Findings
The Chaoshan migrants played an important role in introducing the sha-cha sauce to postcolonial Tainan, and this input bolstered the beef consumption among Taiwanese. The production of sha-cha provided a reliable source of income for these migrants in Tainan, and major businesses like the Bull-Head became the international brands of Taiwanese food products.
Research limitations/implications
The study, though limited to Tainan, reveals the symbiosis between popularization of sha-cha sauce and widespread beef consumption in Taiwan.
Practical implications
This study helps researchers examine the connection between Chinese migrations and food culture.
Originality/value
This paper is an original scholarly investigation of the relationship between food diet and Chaoshan migration in postcolonial Tainan.

Abstract
Purpose
Fabric has complicated anisotropic mechanical behavior because of the woven pattern and complex physical properties. However, most current fabric simulation models are not satisfied because the models are usually geometrical models with stiffness parameters.
Design/methodology/approach
In this paper, the authors present a modeling technique to simulate fabric with Riemann manifold. The proposed nonlinear model is formed with ridge wave-curved surface based on the Riemann zero curvature, and the authors develop a solution to conserve the surface area. It decomposes the m × n matrix constituting the fabric into several batches and processes the fabric dots in batches. In this model, the distance between any two adjacent particles of the fabric's is assumed to be equal, and the area of the curved surface is always constant, and the inclination and decay of the ridge wave-curved surface are also considered.
Findings
As the result, the simulated shape is lifelike. In time cost performance, the model improves the efficiency of the fabric styling and meets the requirements of real-time simulation.
Originality/value
The proposed nonlinear model is formed with ridge wave-curved surface based on the Riemann zero curvature, and the authors develop a solution to conserve the surface area.

Abstract
Purpose
This paper reviews the pros and cons of different parametric modeling methods, which can provide a theoretical reference for parametric reconstruction of 3D human body models for virtual fitting.
Design/methodology/approach
In this study, we briefly analyze the mainstream datasets of models of the human body used in the area to provide a foundation for parametric methods of such reconstruction. We then analyze and compare parametric methods of reconstruction based on their use of the following forms of input data: point cloud data, image contours, sizes of features and points representing the joints. Finally, we summarize the advantages and problems of each method as well as the current challenges to the use of parametric modeling in virtual fitting and the opportunities provided by it.
Findings
Considering the aspects of integrity and accurate of representations of the shape and posture of the body, and the efficiency of the calculation of the requisite parameters, the reconstruction method of human body by integrating orthogonal image contour morphological features, multifeature size constraints and joint point positioning can better represent human body shape, posture and personalized feature size and has higher research value.
Originality/value
This article obtains a research thinking for reconstructing a 3D model for virtual fitting that is based on three kinds of data, which is helpful for establishing personalized and high-precision human body models.

Abstract
Purpose
This paper aims to study the motivations for purchasing protective products.
Design/methodology/approach
Empirical microeconomic research.
Findings
The results show that comparing with ordinary families, families vulnerable to environmental conditions, including prepregnant, pregnant and postpartum families, are not intended to consume more protective products. Among the above three types of families, postpartum families consume the most, followed by pregnant families, and prepregnancy families consume the least. The results also showed that a higher level of economic development, more prevalent Internet access and higher levels of education also increase the consumption of protective products.
Originality/value
New dataset and new empirical results.
