China is experiencing tremendous changes of rapid urbanization and aging society. The development of age-friendly communities (AFCs) has been encouraged for improving health and well-being of older adults. Hence, this study aimed to deepen the understanding of AFCs in China and to investigate the integrated relationships between AFCs and the quality of life (QoL) of older adults, using a large-scale questionnaire survey.

A questionnaire survey was conducted in Hefei, China, to investigate the complicated relationships between the components of AFCs and the QoL of older adults. Ultimately, 1,383 valid questionnaires were collected from senior respondents aged more than 60 years. Several statistical methods, including reliability analysis, correlation analysis and structural equation modeling (SEM), were adopted to develop an integrated model for AFC components and the QoL of older adults.

Six AFC components and four older adults' QoL factors were identified. The SEM results revealed integrated relationships between specific AFC components and the QoL of older adults: (1) physical QoL was affected by outdoor spaces, public transportation, housing and community and health services; (2) psychological QoL was predicted by most of the AFC components except community and health services; and (3) environmental QoL and social QoL were both influenced by outdoor spaces, communication and information and community and health services.

In order to enhance the QoL of older adults, it is suggested that outdoor spaces need to be enlarged by fully using the facilities and playgrounds of middle schools and renovating the older buildings. The locations of public transportation stations are recommended to be revised to be within a 5-minute walking distance of senior residents. Improvements to the social environment of AFCs, by increasing the coverage of medical services and creating multiple approaches to recreational activities, are encouraged.

These findings have empirical significance for urban planners and policy-makers in regard to identifying major components of AFCs and understanding the effect of those components on the QoL of older adults.

The purpose of this paper is to investigate whether US regulatory actions around reverse mergers (RM) have exerted any spillover effects on the Chinese firms listed in China and whether Chinese firms have exhibited lower financial reporting quality than their US counterparts.

To test the possible spillover effect, this paper calculates three-day cumulative average abnormal returns (CAAR) and the aggregate CAAR for a series of US regulatory actions in 2010 and 2011. The study then compares the accrual quality, conditional conservatism, and information content of accruals of Chinese firms and US firms.

The paper documents a spillover effect of US actions around RM on Chinese stocks listed in China. Overall results do not support the perception that Chinese firms have lower financial reporting quality than their US counterparts.

While this study provides evidence consistent with investors perceiving poor financial reporting quality among Chinese firms, that perception is not justified by empirical evidence.

Investors need not be overly concerned about the financial reporting quality among the Chinese firms when they make asset allocation decisions.

A reality check is important given that perceptions may be outdated, biased, misleading, and costly.

This study puts the financial reporting quality of Chinese firms into perspective helping global investors assess information risk for optimal resource allocation.

The purpose of this paper is to investigate the effect of Na₂SiO₃ concentration on the microstructure and corrosive properties of microarc oxidation (MAO) coating on Al-Mg-Sc alloy and explore microstructure evolution rule of Al substrate in the contact area.

The Na₂SiO₃ concentration in electrolytes influenced the microstructure and corrosion behavior of MAO coatings. Instantaneous high temperature and high pressure due to microarc discharge caused annealing treatment. The corrosive behavior of the MAO coating was featured with polarization curves and electrochemical impedance spectrum in 3.5 Wt.% NaCl solution.

The substrate in the contact area existed the instantaneous annealing treatment, which caused obvious recrystallization. The coating prepared in electrolyte containing 7 g/L Na₂SiO₃ exhibited the highest protective properties in 3.5 Wt.% NaCl solution.

MAO treatment could increase the corrosion resistance by producing a protective layer on the Al-Mg-Sc alloy surface at a suitable Na₂SiO₃ concentration and microstructure evolution rule of Al substrate in the contact area was obtained.

This paper aims to present a novel scheme of multiple vanishing points (VPs) estimation and corresponding lanes identification.

The scheme proposed here includes two main stages: VPs estimation and lane identification. VPs estimation based on vanishing direction hypothesis and Bayesian posterior probability estimation in the image Hough space is a foremost contribution, and then VPs are estimated through an optimal objective function. In lane identification stage, the selected linear samples supervised by estimated VPs are clustered based on the gradient direction of linear features to separate lanes, and finally all the lanes are identified through an identification function.

The scheme and algorithms are tested on real data sets collected from an intelligent vehicle. It is more efficient and more accurate than recent similar methods for structured road, and especially multiple VPs identification and estimation of branch road can be achieved and lanes of branch road can be identified for complex scenarios based on Bayesian posterior probability verification framework. Experimental results demonstrate VPs, and lanes are practical for challenging structured and semi-structured complex road scenarios.

A Bayesian posterior probability verification framework is proposed to estimate multiple VPs and corresponding lanes for road scene understanding of structured or semi-structured road monocular images on intelligent vehicles.

The purpose of this study is to evaluate service robots as an alternative service provider that can reduce customers’ social discomfort in hospitality service encounters. Specifically, the authors discuss when and in what scenarios service robots can alleviate such social discomfort and explain this effect from the perspective of dehumanization.

Following a social constructivist paradigm, the authors adopt a qualitative research design, gathering data through 21 semistructured interviews to explore why the presence of service employees causes customers’ social discomfort in hospitality service encounters and how service robots alleviate such discomfort.

This study’s results suggest that both the active and passive engagement of service employees are sources of customers’ social discomfort in hospitality service encounters; thus, adopting service robots can help reduce such discomfort in some scenarios. Customers’ differentiating behaviors, a downstream effect of social discomfort, are also addressed.

Service robots can reduce customers’ social discomfort in certain scenarios and influence their consumption behaviors. This finding offers actionable insights regarding the adoption of service robots in hospitality service encounters.

This research enhances the understanding of social discomfort in hospitality service encounters and expands the research on service robots. To the best of the authors’ knowledge, it is the first attempt to reveal the bright side of robots in service encounters from a dehumanization perspective.

Aging-friendly environments have been encouraged to develop at the city level, district level and community level in China. In the process of rapid urbanization, the state of aging-friendly communities in old and new neighborhoods is disparate. Hence, the purpose of this paper is to investigate aging-friendly communities and identify the disparities in old and new neighborhoods.

A total of 1,172 elderly respondents completed the survey. Of these, 576 seniors lived in an old community developed before 2000, and 596 lived in a new community developed after 2000. In total, 17 physical environment factors and 10 social environment factors were identified.

The results indicated that public spaces, facilities and transportation in old neighborhoods were inferior to those in new neighborhoods. Most social environment factors in new neighborhoods achieved higher satisfaction levels than those in old neighborhoods. The satisfaction levels of aging-friendly community factors in both old and new neighborhoods were below the expectation levels of elders.

In order to improve physical aging-friendly environments in old neighborhoods, it is suggested that full use is made of school facilities and the renovation of old buildings. The locations of public transportation stations in new neighborhoods are recommended to be revised within 5-min walking distances of senior residents. Both old and new neighborhoods are encouraged to improve social aging-friendly environments by increasing the coverage of medical services and creating multiple approaches to recreation activities.

These findings have empirical significance for urban planners and policy makers, in regard to identifying disparities between old and new neighborhoods, and understanding the equitable allocation and distribution of urban resources.

This study provides real-world evidence for the relationship between strategic communication from a global/multinational perspective and the effectiveness of corporate message strategies in the context of environment risk communication. Among sustainability issues, particulate matter (PM) air pollution has threatened the health and social wellbeing of citizens in many countries. The purpose of this paper is to apply the message framing and attribution theories in the context of sustainability communication to determine the effects of risk message characteristics on publics’ risk responses.

Using a 2 (message frame: gain vs loss) × 2 (attribution type: internal vs external) × 2 (country: China vs South Korea) between-subjects experimental design, the study examines the message framing strategies' on publics' risk responses (i.e. risk perception, risk responsibility attribution held toward another country and sustainable behavioral intention for risk prevention).

Findings include (1) main effects of message characteristics on participants’ risk responses; (2) the impact of country difference on participants’ differential risk responses and (3) three-way interactions on how risk message framing, risk threats type and country difference jointly affect not only participants’ risk perception and risk responsibility attribution but also their sustainable behavioral intention to prevent PM.

Although this study used young–adult samples in China and South Korea, the study advances the theory building in strategic environmental risk communication by emphasizing a global/multinational perspective in investigating differences among at-risk publics threatened by large-scale environmental risks.

The study's findings provide evidence-based implications such as how government agencies can enhance the environmental risk message strategy so that it induces more desired risk communication outcomes among at-risk publics. Insights from our study offer practical recommendations on which message feature is relatively more impactful in increasing intention for prosocial behavioral changes.

This study on all measured risk responses reveals important differences between at-risk young publics in China and South Korea and how they respond differently to a shared environmental risk such as PM. The study's findings provide new evidence that media coverage of global environmental issues needs to be studied at the national level, and cross-cultural comparisons are imperative to understand publics’ responses to different news strategies. Thus, this study offers implications for practitioners to understand and apply appropriate strategies to publics in a social way across different countries so as to tailor risk communication messaging.

This study offers new insights to help connect message framing effects with communication management practice at the multi-national level, providing recommendations for government communication practitioners regarding which PM message features are more likely to be effective in forming proper risk perception and motivate sustainable actions among at-risk publics in different countries.

This study aims to critically review the research on the phenomenon of discrimination in hospitality and tourism services to identify the key thematic areas, scenarios, antecedents and consequences; to provide theoretical propositions for future research; and to propose practical strategies to reduce discrimination and to improve equality in the field.

This paper adopts the preferred reporting items for systematic reviews and meta-analyses guidelines to collect relevant academic work on discrimination in hospitality and tourism services from 1985 to 2020 and critically reviews and analyses the studies through bibliometric analysis, content analysis and critical analysis.

The findings show that the main sources of discrimination in hospitality and tourism services include sexism, racism, ethnocentrism, lookism and ego-altruism. Discrimination-related research has temporal and geographical variations. A research map is proposed to present existing knowledge of discrimination in hospitality and tourism services, which indicates that while the impacts (at the individual, organizational and institutional levels) of discrimination in hospitality and tourism services have been thoroughly researched, the nature and characteristics of the phenomenon remain context-based and poorly conceptualized.

An anti-discrimination guideline for hospitality and tourism practitioners is designed to cope with and eliminate discriminatory situations. This evidence-based guideline provides useful coping strategies based on the prevent–monitor–manage principle.

This paper is comprehensive in its scope, methodology and wide coverage of discrimination-related research in hospitality and tourism services. It is the first attempt to review this phenomenon in the existing literature and identifies the research gaps and future research agendas.

State-owned firms play important roles in Chinese cross-border acquisition (CBA) activities. However, compared with private firms, state-owned firms have a lower likelihood of acquisition completion and take longer to complete a deal. This paper aims to determine why this phenomenon exists and how state-owned firms can overcome the constraints of their identity.

By integrating organizational learning theory with institutional theory, this paper attempts to answer the research questions from a legitimacy perspective. Employing Chinese CBA data from 1982 to 2014, the authors use a logit model and a random effects model to test the hypothesis.

The results show that a state-owned identity easily causes legitimacy concerns among host country regulatory agencies; thus, it may result in longer and more uncertain evaluation behaviors, which lead to a lower likelihood of CBA completion and a longer deal duration. Only experience with failed acquisitions can increase CBA completion probability. Furthermore, in very complex decision-making environments, such as that surrounding deal duration, only specific types of experience (i.e. experience of failed international acquisitions) can trigger learning behavior, whereas general experience (i.e. failed acquisition experience) has little influence. Favorable bilateral relationships may not improve the completion rate and efficiency of state-owned firms, but high-quality host country institutions lead to a higher likelihood of CBA completion among state-owned firms; however, this may be not conducive to decreasing the time needed to complete an acquisition deal.

First, by discussing the completion rate and duration of CBAs conducted by state-owned firms and analyzing the factors that influence them, this paper enriches and develops the theory of organizational overseas mergers and acquisitions (M&As). Second, by adopting a legitimacy perspective and integrating institutional theory, the authors theorize how state-owned status influences firms’ M&A completion rate and time and test the hypotheses empirically; thus, this paper improves and deepens institutional theory. Third, by discussing how different types of experience (i.e. successful experience vs failed acquisition experience) influence the acquisition completion rate and duration and how general experience and specific types of experience affect these two dependent variables differently, this paper explains how state-owned firms can learn effectively from experience, contributing to organizational learning theory.

Positioning is a key task in most field robotics applications but can be very challenging in GPS‐denied or high‐slip environments. The purpose of this paper is to describe a visual odometry strategy using only one camera in country roads.

This monocular odometery system uses as input only those images provided by a single camera mounted on the roof of the vehicle and the framework is composed of three main parts: image motion estimation, ego‐motion computation and visual odometry. The image motion is estimated based on a hyper‐complex wavelet phase‐derived optical flow field. The ego‐motion of the vehicle is computed by a blocked RANdom SAmple Consensus algorithm and a maximum likelihood estimator based on a 4‐degrees of freedom motion model. These as instantaneous ego‐motion measurements are used to update the vehicle trajectory according to a dead‐reckoning model and unscented Kalman filter.

The authors' proposed framework and algorithms are validated on videos from a real automotive platform. Furthermore, the recovered trajectory is superimposed onto a digital map, and the localization results from this method are compared to the ground truth measured with a GPS/INS joint system. These experimental results indicate that the framework and the algorithms are effective.

The effective framework and algorithms for visual odometry using only one camera in country roads are introduced in this paper.
