This study aims to present a model and analysis of automotive body outer cover panels (OCPs) assembly systems to predict assembly variation. In the automotive industry, the OCPs assembly process directly influences the quality of the automobile body appearance. However, suitable models to describe variation propagation of OCPs assembly systems remain unknown.

An adaptive state space model for OCPs assembly systems is introduced to accurately express variation propagation, including variation accumulation and transition, where two compliant deviations make impacts on key product characteristics (KPCs) of OCP, and the impacts are accumulated from welding process to threaded connection process. Another new source of variation from threaded connection is included in this model. To quantify the influence of variation from threaded connection on variation propagation, the threaded connection sensitivity matrix is introduced to build up a linear relationship between deviation from threaded connection and output deviation in KPCs. This matrix is solved by homogeneous coordinate transformation. The final deviation of KPCs will be transferred to ensure gaps and flushes between two OCPs, and the transition matrix is considered as a unit matrix to build up the transition relationship between different states.

A practical case on the left side body structure is described, where simulation result of variation propagation reveals the basic rule of variation propagation and the significant effect of variation from threaded connection on variation propagation of OCPs assembly system.

The model can be used to predict assembly variation or potential dimension problems at a preliminary assembly phase. The calculated results of assembly variation guide designers or technicians on tolerance allocation, fixture layout design and process planning.

Several parameters set economic growth, and one of them is innovation. Thus, it is vital to realize the proper motives for a firm to innovate. The key actors in innovation systems – such as firms, research institutions, academia, and standards developing communities – affect knowledge ­creation, contribute to its diffusion and use, and set the global innovation capacity. Additionally, the market-driven and the worldwide open paradigm may aid to ensure stable and reliable integration, interactive abilities, and active collaborations to drive international innovation and its ­concepts forward. The World Trade Organization (WTO) is an international organization that assembles principles to produce such standards as mentioned above, so as to ensure a prosperous future globally. Global cooperation, openness, interaction, and the generation of motives for innovation are some of the principles that WTO embraces, and all of these are to benefit humanity from free market and trade growth, leading to triumph through innovation. Overall, this chapter examines the significant role of WTO in trade policy uncertainty and how innovation is ensured and stimulated by WTO regarding the specific case of the Chinese market.

Accelerators provide a way for entrepreneurs to capitalize on new knowledge and technology regarding sport. The advantage of accelerators is that they can utilize the wisdom of crowds in order to facilitate a quick introduction into the marketplace of new ideas. This is crucial in the competitive sport industry, which relies on utilizing knowledge intensive products and services for competitive reasons. Knowledge in a sport context can be hard to describe as it can refer to processes that enable better production processes. For this reason, it is useful to understand how knowledge is a source of power in the sport market and how it can be used strategically. This chapter focuses on issues such as knowledge management and knowledge hoarding as a way to gain a competitive advantage in the sport industry, thereby linking the research on accelerators to a knowledge perspective in the sport context.

This paper aims to document and to illustrate highly usable research: a practical framework for realizing the sustainable operations of the high investment, technology-intensive high-speed railways in China. Also, for the first time, we draw a broad, metaphorical relationship between railways within a country to Chinese meridian lines within a human body. These are similar in enabling flows across the country and human body.

Employing Chinese case studies, we attempt to apply methodological procedures involving operational, financial and developmental in realizing the sustainability of high-speed railways. Critical criteria are emphasized for efficiency, financial viability and long-term funding sustained development of high-speed railways in the Chinese context. Policymakers may utilize the illustrative framework in working toward specific recommendations that may be implementable.

Three critical aspects to sustainability are operational, financial solvency and developmental. Our empirical investigations result in the working out of the procedural aspects as well. Based on this three-way classification, we design an evaluative framework for realizing sustainability of high-speed railways. Our insights are based on the social reality of China. Thus, we argue that cash handouts by government are necessary solutions, given the intensive capital investments required of high-speed railways for strongly positive externalities generated. On developmental aspects of sustainability, there should be rational, in-depth studies conducted so as to lead to rational choices of sites. Strong passenger flows coupled with affordability of fares are the twin guarantees of continuing, profitable performances.

This work on sustainability is globally, most highly significant for two reasons. First, railway is one fundamental mean of transportation within China. Thus, the sustainability of railway matters to a majority of the 1.3 billion people. Second, transport volume of China’s railway is the world’s largest. By developing such a comprehensive methodology, we hope to enhance how top management of Chinese Railways may keep the high-speed railways sustainable into the future.

This paper is socially highly significant, especially in the context of what has happened in recent years in China’s railway industry, and may contribute by providing both the regulators and management with an objective methodology in future projects assessment within high-speed railway.

This paper develops an overall framework for enabling management to realize sustainability of high-speed railway within China. The ideas, concepts and methodologies are likely beneficial to top management, regulators and policymakers within the railway transportation, a state monopoly.

Enterprise social media (ESM) are frequently used in enterprises for daily operation. Although many researchers have attempted to understand the antecedents and consequences of ESM use, the integrated model, boundary conditions and mechanism of the impact of ESM use on performance are still unclear. This study fill this research gap by adopting a grounded theory approach to study how ESM use affects employee performance.

Choosing representative cases, the authors collected interview data and analyzed the data using open coding, axial coding and selective coding.

The results showed four main categories including ESM use, work efficiency, emotional maintenance and work performance, as well as 14 sub-categories. This paper also constructs a model of the impact of ESM use on work performance. In addition, results showed that ESM use affects employees' work performance through work efficiency and emotional maintenance, and frequency of use and individual characteristics may moderate this process.

This study’s results contribute to the existing ESM literature by finding the integrated model, boundary conditions and mechanism of the impact of ESM use on performance. The authors also contributed to the social media literature by finding 14 sub-categories and four main categories including ESM use, work efficiency, emotional maintenance and work performance. The conclusion of this paper provides guidance and reference for the use and management of internal social media in enterprises.

This paper aims to disseminate the results of research aiming to identify the prevalence of dysphagia and related clinical factors in nursing home residents.

A cross-sectional descriptive study was developed, including 99 residents in five nursing homes. A sociodemographic questionnaire and the Gugging Swallowing Screen for dysphagia screening were used for data collection.

The prevalence of dysphagia was 59.59%. A significant correlation was found between dysphagia and worse scores for fall risk, pressure ulcer, level of independence for activities of daily living and cognitive functioning.

Results should be interpreted carefully due to sample size and specific country context. A larger sample must be achieved in further research.

Nurses must receive proper training to perform systematic dysphagia screening, and it should be considered, given the high prevalence, the inclusion of professionals specially trained for rehabilitating dysphagic residents in nursing home teams.

The social and economic burden of dysphagia, in addition to all the implications on the person’s quality of life, requires a differentiated focus on this issue by nursing home managers.

Nursing homes have nurses providing health care; however, trained professionals for dysphagia treatment commonly are not. These results highlight the importance of systematic screening for dysphagia in all residents, thus promoting timely intervention to prevent respiratory and nutritional complications.

Employee participation enhances organizational effectiveness. Trust in employees leads to encouragement and acceptance of participation in decision making. There has been recent and growing interest in understanding the basic characteristics of managerial mechanisms within township‐village enterprises (TVEs) in China and how these affect organizational performance. This empirical study investigates how trust influences managers’ decision‐making behavior in the township‐village enterprises in China. The findings of the study suggest that, although TVE managers develop a high level of trust in the dependability, predictability and good faith of their employees, only trust in employee dependability is positively related to participation in the decision‐making process.

The purpose of this paper is to examine borrowing capacity (BC) of government-owned firms and whether real earnings management (REM) activities moderate the sensitivity of firm BC to government ownership.

A simultaneous equation analysis is applied to study 210 Tunisian non-financial firms over the 2001–2014 period.

The empirical results provide substantial evidence indicating that government-owned firms have higher BC and significant REM than other firms; the relationship between government ownership and firm BC is partially moderated by REM activities.

The findings imply that the implicit credit guarantee of government is not necessarily the unique determinant of firm BC and highlight the role of lenders in monitoring discretionary real transactions in government-owned and protected firms. These implications should be taken in to account by public sector policy makers. In particular, the findings predict that the current government accounting reform in Tunisia on the basis of IPSAS will, probably, improve information quality, but it is still insufficient to control real activities in public institutions.

This study extends a growing research stream on the relationship between BC and government ownership by focusing on the moderating effect of REM on this relationship and by considering the endogeneity issue. The findings provide evidence that government-owned firms use REM practices to improve their BC. Examining these practices in developing countries provides an opportunity to evaluate the efficiency of their public sector reforms and their effect on a firm’s performance and financing decisions.

Construction sustainability (CS) is a strategic reaction to the sustainability expectations of the construction industry's external stakeholders. The extant literature has viewed the environmental, social and economic dimensions of CS as having independent effects on financial performance. Due to the influence of common stakeholders, however, interactions in these dimensions will be present in their effect on financial performance. Accordingly, this study identifies the mechanisms of the interactions between the three CS dimensions and how they jointly affect financial performance.

Content analysis of GRI reports of 60 large construction organisations, followed by a hierarchical regression analysis was used to identify the interactions between environmental, social and economic CS in their effect on financial performance.

Economic CS was found to indirectly, and not directly, affect financial performance, the effect being mediated by both environmental and social CS. Environmental CS was found to have a strong negative effect on financial performance, whilst social CS was found to have a strongly significant positive effect on financial performance.

The motivation for engaging in CS is that investment in economic CS will have a positive effect on both environmental and social CS outcomes, which, in turn can have a combined effect on financial performance.

This is one of the first studies investigating the effect of interactions between the environmental, social and economic CS dimensions on the financial performance of construction organisations. It is also one of the first studies that applies a sociotechnical framework to this relationship.
