Abstract

Purpose

The purpose of this paper is to re-examine the effectiveness of price limits on stock volatilities in China over a more recent time period spanning from 2007 to 2012. The motivation stems from the fact that very high stock market volatilities are observed in China and we are sceptical of the volatility mitigating effect claimed by advocates of price limits.

Design/methodology/approach

The effectiveness of price limits on volatilities is examined using an event study methodology and within an expanded framework of volatility-volume relationships. The sample stocks include the 300 component stocks of the CSI300 Index.

Findings

Both event study and regression analysis suggest that price limits exaggerate market volatilities by causing volatility spillovers. The destabilising effect is much more pronounced for small firm stocks and when the market falls. In addition to the informational source of volatilities (represented by volume), price limits create another non-trivial frictional source of volatilities in China’s stock market.

Originality/value

This research is the first to re-examine the price limit effect in China’s stock market in an expanded framework of volatility-volume relationships. It identifies price limits, in addition to information, as another non-trivial frictional source of volatilities. The findings derived from a recent sample period confirm the conventional view of inefficiency of price limits raised by Fama (1989) and provide evidence in support of the pervasive trend of stock market deregulations.

Abstract

Purpose

Recognizing the differences between generations Y and Z, this exploratory study uses generational cohort theory as a framework to examine the brand perception of McDonald's, an international brand which has grown up with consumers for over 30 years in China. The paper aims to discuss this issue.

Design/methodology/approach

Measures of brand perception was built based on Aaker's brand personality model. A total 1,103 valid questionnaires were collected through an online survey platform. Factor analysis is the primary method to analysis the data.

Findings

The findings of this study reveal a favourable brand perception of McDonald's among young Chinese consumers which is consistent with Aaker's brand personality model and support the use of generational cohort theory as a market segmentation tool for brand perception. The differences between the two generational cohorts are not shown to be significant.

Originality/value

The most important contribution of this study is the evaluation of the personality of a major brand in China for Gen Z, a topic with very little existing research. Also, this research suggests future in-depth research into generational cohort theory in a Chinese context by recognizing homogeneity and heterogeneity exist simultaneously between generational cohorts.

Abstract

Purpose

While performance demands in the natural world are varied, graded lattice structures reveal distinctive mechanical properties with tremendous engineering application potential. For biomechanical functions where mechanical qualities are required from supporting under external loading and permeability is crucial which affects bone tissue engineering, the geometric design in lattice structure for bone scaffolds in loading-bearing applications is necessary. However, when tweaking structural traits, these two factors frequently clash. For graded lattice structures, this study aims to develop a design-optimization strategy to attain improved attributes across different domains.

Design/methodology/approach

To handle diverse stress states, parametric modeling is used to produce strut-based lattice structures with spatially varied densities. The tailored initial gradients in lattice structure are subject to automatic property evaluation procedure that hinges on finite element method and computational fluid dynamics simulations. The geometric parameters of lattice structures with numerous objectives are then optimized using an iterative optimization process based on a non-dominated genetic algorithm.

Findings

The initial stress-based design of graded lattice structure with spatially variable densities is generated based on the stress conditions. The results from subsequent dual-objective optimization show a series of topologies with gradually improved trade-offs between mechanical properties and permeability.

Originality/value

In this study, a novel structural design-optimization methodology is proposed for mathematically optimizing strut-based graded lattice structures to achieve enhanced performance in multiple domains.

Abstract

Purpose

The purpose of this paper is to study the corrosion behavior of Q235 steel in saturated acidic red and yellow soils.

Design/methodology/approach

The corrosion behavior of Q235 steel in saturated red and yellow soils was compared by weight-loss, SEM/EDS, 3D ultra-depth microscopy and electrochemical measurements.

Findings

Rp of the steel gradually increases and icorr gradually decreases in both the red and yellow soils with time. The Rp of the steel in the red soil is lower, but its icorr is higher than that in the yellow soil. The uniform corrosion rate, diameter and density of the corrosion pit on the steel surface in the red soil are greater than those in the yellow soil. Lower pH, higher contents of corrosive anions and high-valence Fe oxides in the red soil are responsible for its higher corrosion rates and local corrosion susceptibility.

Originality/value

This paper investigates the difference in corrosion behavior of carbon steel in saturated acidic red and yellow soils, which can help to understand the mechanism of soil corrosion.

Abstract

Purpose

The purpose of this study is to examine whether banks’ commitment to corporate social responsibility (CSR) is related to the diversification of their activities and whether CSR, as a result, affects banks’ risk profile.

Design/methodology/approach

Using a sample of 215 publicly traded U.S. bank holding companies between 1996 and 2016, this study applies regression analysis to examine the links between CSR and activity diversification and risk-taking. It also conducts a mediation test to determine whether CSR affects risk through its influence on banks’ activity diversification.

Findings

The results of this study show that banks engaging in positive CSR activities significantly increase the diversification of their banking activities, consistent with the theory that CSR serves as an implicit risk hedging strategy. Mediation analysis provides evidence that this translates into more stable and less risky banks.

Originality/value

This study contributes to the literature by suggesting that activity diversification is a channel through which CSR reduces bank risk and improves asset quality.

Abstract

Purpose

The purpose of this paper is to present a new human dynamics model to explain the process of verified users' (VUs) posting on Sina micro-blog.

Design/methodology/approach

A common human dynamics research method with three steps is applied. Firstly, a large-scale behavioral dataset is collected involving 495 VUs and five topics on Sina micro-blog. Second, five important indicators that reveal the characteristics of posting behavior are analyzed. Then, a quantitative model is constructed to describe the process of posting behavior, and its validity is verified by simulations.

Findings

Three important characteristics of VUs' micro-blog posting behavior are observed: fat-tailed distribution, fluctuation and periodicity. These characteristics do not fit the assumption of interest-driven models proposed by previous literature. An optimized task-driven model is introduced to describe this complex phenomenon mathematically. The model is verified on empirical data, confirming that task-driven models can be optimized to explore information behavior on social media.

Originality/value

Being different from previous studies that mainly describe common users' posting behavior on social media by applying interest-driven models, this paper customizes an optimized task-driven model for VUs, who mainly treat social media as a platform for work and play a crucial role in information creation on social media.

Abstract

Purpose

The preservation and disappearance of indigenous people’s traditional knowledge system, under mainstream social culture immersion and fusion, have presented a dynamic and changing acculturation interactive relationship impacting Truku women’s health concepts. Thus, the purpose of this paper is to explore how the traditional Gaya knowledge system and mainstream culture confinement care model affect the beliefs and behaviours of postpartum self-care amongst contemporary Truku women.

Design/methodology/approach

An ethnographic semi-structured method, based on cultural care factors and the Leininger Sunrise Model, was conducted to interview 17 Truku women with childbearning experience in eastern Taiwan. As data were collected, UDIST Vivo 11.0 software was applied for analysis.

Findings

Amongst the three knowledge system categories, namely, traditional, mainstream and reconstruction, the traditional knowledge system, including Gaya norms, provides the overall cultural value of a Truku family. While taboo is inherited through the experience of the elders, the mainstream knowledge system favours the Han. However, the reconstruction knowledge system highlights the “functional” response strategies based on Truku women’s comfort and conveniences.

Originality/value

Limited relevant studies have focused on the health and postpartum self-care knowledge of ethnic Truku women in Taiwan. The results are expected to provide clinical medical personnel with a reference and strengthen cultural sensitivity and the ability to implement the cultural congruency care of postpartum indigenous women in Taiwan.

Abstract

Purpose

This article explores the scientific construction of library olfactory space, based on the case of the olfactory space in the Jiangsu University library. It specifically focuses on understanding the interaction between the physical architectural space of the library and users’ olfactory perception and behavioral activities, with the ultimate goal of creating a deeply integrated olfactory experience in the Jiangsu University Library.

Design/methodology/approach

In this article, an empirical research method was used to gather perceptions from 30 university student users regarding the library olfactory space and to understand their olfactory preferences and requirements for its construction. Through qualitative analysis of the interview texts, the study identified correlations between user perceptions and elements of the library olfactory space.

Findings

The qualitative analysis of user interview texts and results from the library olfactory space design experiment contributed to the design proposal for the Jiangsu University Library olfactory space. The design proposal for the Jiangsu University Library olfactory space is provided and includes library architecture, activity context, functional services, olfactory experience design and technological applications.

Research limitations/implications

This case study takes the environment, development strategy and user needs of the Jiangsu University Library as its unique research background and as such is not universal or generalizable to other libraries.

Originality/value

This article differs from others by advocating for the innovative architectural spatial design of libraries through olfactory experience, breaking the traditional perception of libraries as solely through visual and auditory senses.

Abstract

Purpose

The purpose of this paper is to explore the relationship between culture and regional innovation performance in China where innovation is deemed as a key for sustainable economic development. The diversity of China’s regional culture and its rising economic and innovative capability enhancement provides an opportunity for such an exploration.

Design/methodology/approach

This paper adopts the GLOBE’s nine cultural dimensions to empirically examine the relationship between culture and Chinese regional innovation performance through multiple regression analysis.

Findings

The study results find that performance orientation and gender egalitarianism have positive and significant influences on regional innovation performance, while institutional collectivism has a negative and significant influence. The remaining six GLOBE cultural dimensions show no significant effect on regional innovation performance.

Originality/value

To the best of the authors’ knowledge, this is the first research exploring the relationship between culture and regional innovation performance in a Chinese context by using GLOBE’s cultural dimensions that are deemed as a valuable empirical alternative to Hofstede’s cultural measures. The results of this study help further the understanding of the cultural influence in China’s regional innovation performance.

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.
