Abstract
Purpose
The purpose of this paper is to examine the disparities in stress between rural and urban police officers in China.
Design/methodology/approach
Data for this study were collected from a national police university in China in 2017. In total, 608 Chinese police officers were surveyed representing those attending in-service training program in the university.
Findings
Results showed that rural police officers exhibited a higher level of somatization compared to their urban counterparts, whereas no rural–urban differences were detected for other stress dimensions – anxiety and depression. Additionally, this study suggests that perceived constraints in resources and training partially mediate the observed rural–urban disparities in somatization.
Research limitations/implications
This study is based on a convenient sample of Chinese police officers, which restricts the generalizability of the results.
Practical implications
To reduce stress among police officers, China needs to make more investments in resources and training programs in its rural policing.
Originality/value
A review of literature reveals that studies comparing police stress between rural and urban areas are rare. Additionally, China, as the largest developing nation in the world, remains under-studied with respect to stress among its police officers.

Abstract
Purpose
The purpose of this paper is to combine basic movie information factors, external factors and review factors, to predict box-office performance and identify the most crucial factor of influence for box-office performance.
Design/methodology/approach
Five movie genres and first-week movie reviews found on IMDb were collected. The movie reviews were quantified using sentiment analysis tools SentiStrength and Stanford CoreNLP, in which quantified data were combined with basic movie information and external environment factors to predict movie box-office performance. A movie box-office performance prediction model was then developed using data mining (DM) technologies with M5 model trees (M5P), linear regression (LR) and support vector regression (SVR), after which movie box-office performance predictions were made.
Findings
The results of this paper showed that the inclusion of movie reviews generated more accurate prediction results. Concerning movie review-related factors, the one that exhibited the greatest effect on box-office performance was the number of movie reviews made, whereas movie review content only displayed an effect on box-office performance for specific movie genres.
Research limitations/implications
Because this paper collected movie data from the IMDb, the data were limited and primarily consisted of movies released in the USA; data pertaining to less popular movies or those released outside of the USA were, thus, insufficient.
Practical implications
This paper helps to verify whether the consideration of the features extracted from movie reviews can improve the performance of movie box-office.
Originality/value
Through various DM technologies, this paper shows that movie reviews enhanced the accuracy of box-office performance predictions and the content of movie reviews has an effect on box-office performance.

Abstract
This paper is a study of the current trends and conditions of electronic resources for Chinese studies, based on a recent survey on the Internet of 29 Chinese libraries in North America and eight Chinese libraries in China, Taiwan and Hong Kong. The survey discussed current electronic resources for Chinese studies, with a union list of major Chinese language databases currently used in libraries in Asia and the US. Current views on the use and development of electronic resources for Chinese studies were summarised.

Abstract
Purpose
China's resource allocation mechanism in education has become an important factor in determining residential access to educational resources. The purpose of this paper is to analyze the impacts made by the individual natures of buyers, the external environment, as well as the characteristics of residential properties on the willingness price of buyers. The study's aim is to lay theoretical foundations for the determination of problems related with the matters under consideration.
Design/methodology/approach
Using the panel data of 54 districts and counties in Beijing, Shanghai, Guangzhou and Shenzhen, the study unifies macro factors and micro factors in a model for empirical analysis.
Findings
Basic education resources can affect housing prices via the “capitalization of education.” The degree of those educational resources’ influence on willingness price changes according to personal income levels, standards of living, housing price fluctuations, the convenience of the residential area and the degrees of urbanization in a district. The greater the buyer's income and standard of living is, the higher is their willingness price. Buyers in urbanized areas prefer increases in educational resources. Increased educational resources increase the values of residential downtown areas. In developed areas with private educational facilities, the role of educational resources in influencing property prices is relatively small.
Originality/value
This paper uses data concerning the consumption and investment of residential properties to build a theoretical model for the willingness price of buyers. It unifies macro factors and micro factors in a single model and presents new results about basic education resources and the willingness price of buyers under different conditions.

Abstract
Purpose
The paper aims to examine theoretically valuation of weather derivatives and their hedging roles in corporate risk management.
Design/methodology/approach
The paper introduces an extended financial market model in which the weather risk is included as an independent random process and examines the effectiveness of weather derivatives and traditional price forwards in a unified theoretical framework. It also provides a no‐arbitrage approach to price weather derivatives, which theoretically combines the actuarial and financial paradigms.
Findings
The results document that corporate leverage level is an essential factor determining the choice between price forwards and weather derivatives. In some cases; weather derivatives outperform price forwards, while in some other cases; a joint use of both instruments is optimal, depending on the firm's risky leverage level. Interestingly, the paper identifies the case when the leverage level is very high, the positive roles of both instruments diminish and the firm is unhedgeable.
Originality/value
The paper provides important insights to investors and hedgers and extends the literature on corporate risk management.

Abstract
Purpose
This paper investigates changes in risk-neutral distribution derived from Taiwan stockindex options under different market conditions. The purpose of this paper is to explore whether individual investor sentiment significantly influences the Taiwan option prices.
Design/methodology/approach
The authors adopt the optimization method to estimate the risk-neutral distribution from the Taiwan stock index options and use the t-test to examine the difference in risk-neutral skewness, kurtosis, and confidence interval between the pre-crisis and crisis periods. This paper tests the impact of individual investor sentiment on risk-neutral skewness and confidence interval in two sub-periods.
Findings
The authors find that errors in individual investors’ expectations significantly influence the Taiwan stock index option prices.
Research limitations/implications
The data concerning the sentiment of speculative institutional investors are incomplete for the Taiwan option market. Therefore, this paper focusses on the analysis of individual investor sentiment. Further research can study the impact of institutional investor sentiment in emerging markets.
Social implications
The previous literature has suggested that option prices reflect information before the information is revealed in stock prices. Therefore, an important implication is to analyze the information quality revealed in option prices by studying whether the changes in option prices are due to investor sentiment or non-sentiment-related components.
Originality/value
Most of the studies in the literature have focussed on the US option market, and their applicability may vary across different microstructures. This paper shows that the influence of individual investor sentiment in an emerging market is different from that in the US market.

Abstract
Purpose
The purpose of this paper is to examine empirically the basis risk and hedging efficiency of temperature‐indexed standardized weather derivatives in hedging weather risks in the US energy industry.
Design/methodology/approach
Within the risk minimization framework, using power load and temperature data, this research analyzes both linear and nonlinear hedging strategies using the two most popular types of standardized indexes – city indexes and regional indexes.
Findings
The results indicate that the city indexes and regional indexes are not consistently superior to each other and the regional indexes should be a good complement to the current exchange‐listed indexes. The results also document that the basis risk is sufficiently low for the diversified power producers serving the US Northeast or Mid‐Atlantic regions in both the summer and winter seasons and California in the summer season. However, the basis risk is very high for the diversified power producers serving California in hedging the weather risk in the winter season. More discrepancies are observed in the hedging efficiency among the power producers serving the Texas region.
Originality/value
This research provides important implications about the survivability and superiority of current and proposed standardized weather contracts and the design of effective standardized weather derivatives for the extant and potential weather markets.

Abstract
Purpose
The purpose of this paper is to introduce a progressive strategy of the National Palace Museum (NPM) using new media art exhibitions as a creative marketing tool to interpret its collection, generate cultural value and navigate the greater global context.
Design/methodology/approach
A review of museum marketing literature and the challenges presented by Taiwan’s sociopolitical situation contextualize discussions on marketing activities and the emergence of museum-commissioned new media art at the NPM within the past two decades.
Findings
Democratic potency inherent in the digital medium has enabled the NPM to transcend the conflicting cultural perceptions surrounding its collection and fulfill the function of market expansion and cultural transmission.
Originality/value
Specialized heritage museums, such as the NPM, do not traditionally create or collect contemporary artworks that engage in ongoing cultural dialogues. This paper brings into view the novelty of using the digital medium to generate cultural value as exemplified in the new media art commissioned by the NPM.

Abstract
Purpose: Despite the significance of filial piety in intergenerational relationships and its important influence on parental health and well-being, few studies have explored the personal meaning of filial piety to older parents. This qualitative study aims to address this question.
Design: Responses to an open-ended question of “What makes a filial child in your view?” from a sample of 432 older parents in a rural Chinese county were collected face-to-face and analyzed using content analysis.
Findings: The personal meaning of filial piety varies. Seven broad themes emerged. These include widely persistent traditional filial piety beliefs (Be obedient, Respect, and Maintain frequent contact and show emotional care), filial piety values similar to filial obligations described in Western cultures (Help older parents when in times of need and Be a good citizen and take good care of themselves and their families), and traditional filial piety norms in the absolute form (Take care of every aspect of the parents’ life and Provide financial and material support to parents). Themes were also compared with dimensions of the intergenerational solidarity model.
Originality: Findings reflect the coexistence of traditional and modern filial values in relation to participants’ interpretation of filial piety, indicating that traditional filial piety beliefs are fading even in one of the least developed areas in China. Implications for interventions enhancing offspring’s filial performance are discussed.
Research limitations: Future studies on the understanding of filial piety from the perspective of offspring are warranted to draw a holistic picture of this topic.

Abstract
Although an important facet of modernist architecture in which function plays a prominent role, building flexibility is not entirely a new concept. Its relevance transcends generations, allowing space and structure to evolve through time. This paper investigates the relationship among main building structures, infill elements, and space by studying examples in ancient Chinese architecture. It reveals the role of building owners, users, and craftsmen from a survey of historical documentation. In studying these examples, it is concluded that craftsmen in ancient China were involved not only during the construction phase but throughout the period of use as well. Thus, in select cases, the relationship between craftsmen and owners or users had been preserved for generations. Finally, this paper suggests potential strategies for the building industry and technology in the move towards sustainable development.
