Abstract
Purpose
The purpose of this paper is to provide an efficient tool for simulating electrospinning process in virtual 3D space and optimizing experimental parameters. The fiber orientation from virtual or real electrospinning process can be easily measured using the image analysis technique. Using the semi-implicit Euler integration, the time integration can be more fast and stable, which enabled optimization of the electrospinning process. Also boundary conditions can be easily adopted during conjugate gradient matrix solving step.
Design/methodology/approach
To simulate the electrospinning process, the authors have adopted a particle-based modeling technique using the molecular dynamics theory, which is known to be suitable for modeling materials with nonlinear and nonhomogeneous behavior such as fibers or fabrics. Gravitational, tensional, and electrostatical forces and their Jacobians were carefully defined and chosen to maintain the stability of the governing equation. Preconditioned conjugate gradient method was used to solve the matrix iteratively with boundary conditions. The 2-D metaball fitting technique, which was applied in the previous research (Sul et al., 2009) on experimental nanofiber scanning electron microscopy images, was utilized with virtual nanofiber images. A staircase function and a new shading language were proposed to automatically calculate the orientation and radius distribution of the graphically simulated electrospun fiber structures. The automatic measurement procedure was verified via graphically designed virtual replica images. Also the orientation tendency acquired from the simulation was compared with that of experimental data.
Findings
Simulation result of fiber orientation showed linear relationship with the collecting drum speed. Use of particle-based method generated a simple system to simulate electrospinning process.
Originality/value
The semi-implicit Euler integration was applied to the electrospinning process and the final linear system was numerically stable to solve.

Abstract
Purpose
The purpose of this paper is to investigate the correlation between university libraries and academic research achievement and analyze if university library resources correlate with academic research achievement.
Design/methodology/approach
The paper seeks to verify the correlation between university libraries and academic research achievement and to examine which university library resources relate to research achievement. A variety of research questions were posed concerning the relationship between a university's library resources and academic research achievement. Structural equation models (SEMs) were developed to answer the research questions. Most research questions posed were affirmatively answered using the SEM process.
Findings
This study confirmed that labor and budget, investment in e‐resources and an investment in university libraries enhances academic research achievement.
Research limitations/implications
An SEM for verifying the correlation between university libraries and academic research achievement was developed in the study.
Originality/value
This study is the first including an investment factor in e‐resources for verifying the correlation between university libraries and academic research achievement.

Abstract
Purpose
The purpose of this research is to account for the internationalization of restaurants. The conceptual framework of upper echelons theory is applied to identify the demographic determinants of internationalization among chief executive officers (CEOs).
Design/methodology/approach
Data from 30 restaurant firms for the period 1999-2013 were collected from a variety of sources, primarily Compustat and Execucomp, based on Standard Industrial Classification (SIC) code 5812, the annual 10-K and public information. A panel feasible generalized least squares model was used as the main instrument of analysis.
Findings
The findings indicate that the CEO gender and share ownership negatively affect the internationalization of restaurant companies, whereas size, the extent of franchising, the type of restaurant and stock options positively affect the degree of internationalization. Additionally, an inverted U-shaped relation exists between CEO tenure and the degree of internationalization.
Practical implications
The presented information may provide shareholders and boards of directors with valuable guidelines regarding the assignment of appropriate managers depending on the extent to which their companies are pursuing internationalization strategies.
Originality/value
Most studies in hospitality sectors have focused only on accounting-based measures to explain strategic decision-making, although proponents of upper echelons theory have argued that CEO attributes influence strategic decisions/changes. This study contributes to the literature on hospitality by identifying the effects of CEO characteristics on internationalization decisions.

Abstract
Purpose
The rise of cultural governance has made cultural democracy important in East Asia. South Korea and China have chosen to develop cultural democracy by means of developing community-based cultural houses. Cultural houses in Korea were first managed from the center but have now been decentralized, and those in China have been developed based on local financing and administration. Since central-local intergovernmental relations, as they relate to public culture, have gone untouched in East Asia, the purpose of this paper is to study how central-local intergovernmental relations have impacted the development of cultural democracy in this area, in order to better understand how public culture should be developed.
Design/methodology/approach
A comparative study of the cases of South Korea and China has been used. The materials and information collected for the study were gathered by a review and an analysis of extant literature, policy documents, data and other materials from the relevant departments of both countries. It was also based on semi-structured interviews conducted with the national cultural departments, regulatory institutions, and with officials and scholars.
Findings
This study shows that central-local intergovernmental relations can have an impact on the management of community-based cultural houses and the effectiveness of cultural democracy’s development. Only complete decentralization that directly invites democratization will provide positive local conditions for cultural democracy’s growth. In short, meaningful governmental responses to local demands and a strong civil society are critical for the advancement of cultural democracy.
Practical implications
This study seeks to provide insights into the relationship between central-local intergovernmental relations and cultural democracy. At the micro project level, cultural project management should be improved; at the medium local level, the public must be made part of any decentralization effort; and at the macro national level, the multiple impacts caused by decentralization need to be considered.
Originality/value
This study is unique in terms of both its research questions and its research area. Central-local intergovernmental relations, as they relate to public culture, have gone comparatively untouched, especially in the context of East Asia. It is in this context that studying how central-local intergovernmental relations impact the development of cultural democracy is worthwhile, in order to better understand how public culture has developed and will be developed in future. A comparative study of the cases of South Korea and China has been used to discover the impacts of different dimensions of central-local decentralization on cultural development.

Abstract
Purpose
The purpose of this paper is to analyze the causal relationships among categories in the China Quality Award (CQA) model based on the Malcolm Baldrige National Quality Award model.
Design/methodology/approach
The paper identifies seven factors from CQA categories: leadership, strategic planning, human resource focus, process management, customer and market focus, information and analysis, and results. Extending the basic Baldrige theory “Leadership drives the system that creates results,” this paper identifies driver (leadership), direction (strategic planning), foundation (information and analysis), system (human resource focus, process management, and customer and market focus), and results(business results). Structural equation model (SEM) is used to analyze the empirical data and estimate the path coefficients among CQA categories.
Findings
First, driver has not only a direct influence on results, but also has an indirect influence on results through system. Leadership has a great influence on foundation and direction. Second, direction affects human resource focus and customer and market focus of system while it has no influence on process management. Third, human resource focus and customer and market focus both affect process management, and process management has a significant impact on results. Fourth, foundation affects direction and all of the categories of system.
Originality/value
There are few studies which try to analyze the causal relationships among categories in the CQA model.

Abstract
There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.
An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).
The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.
In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.
The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.

Abstract
Purpose
Despite the rise in vegan food consumption, vegan restaurants have experienced high turnover rates. Given that non-vegans make up the majority of the customer base, this study explores the critical role of conspicuous consumption motives in driving ambivalence, which, in turn, affects intentions to revisit vegan restaurants.
Design/methodology/approach
Through a purposive sampling method, data were obtained from non-vegans who had experienced dining at vegan restaurants. The proposed relationships within the study framework were analyzed using a PLS-SEM model.
Findings
Results support the significance of the need for uniqueness and the desire for access to elite social strata in shaping conspicuous consumption motives, consequently increasing ambivalence among non-vegans. Interestingly, ambivalence was discovered to positively influence revisit intentions for vegan restaurants. This positive effect was significantly enhanced by perceived objective authenticity in vegan restaurants.
Research limitations/implications
Findings provide novel insights into the existing understanding of vegan consumption, particularly by focusing on non-vegans and their conspicuous consumption motives in the context of dining at vegan restaurants. Our approach expands the research by highlighting the greater significance of objective authenticity over existential authenticity in the context of vegan restaurants, offering practical insights to enhance their operation.
Originality/value
The study provides compelling evidence that non-vegans’ novel and non-altruistic motivations can generate favorable outcomes. Our model can serve as a fundamental baseline for vegan restaurant management, applied to design appropriate operational strategies to attract more non-vegan consumers and increase their likelihood of revisiting.

Abstract
Purpose
In recent years, many of South Korea's most prominent organizations have been involved in large‐scale frauds. These frauds have had a devastating impact on South Korean society and resulted in unnecessary suffering and high levels of unemployment for the middle class. With the aim of understanding the causes of these scandals, this paper takes an in‐depth look at the chaebol organization.
Design/methodology/approach
The paper takes a conceptual approach by first examining chaebols in greater detail. The paper then examines classical fraud theory, including the fraud triangle. The paper then examines chaebol organizations through the lens of the fraud triangle. By doing so, it is possible to understand why chaebols, in particular, are susceptible to fraud and corruption.
Findings
The paper provides evidence to suggest that chaebol organizations have inherent fraud risks. In order to minimize these fraud risks, chaebol organizations must address these issues.
Originality/value
This paper fulfills an important area of research by providing basic information about the relationship between chaebol organizations and fraud.
