This study aims to conduct an empirical investigation of differing perceptions of nine types of urban space and nine visual elements among tourists in destination using a computer vision (CV) approach.

The data for this study was extracted from YFCC 100 M dataset. Nine types of urban space in Beijing were initially identified using a scene recognition model. Subsequently, a semantic segmentation model was applied, which yielded substantial evidence relating to nine visual elements that were used to elicit differing perceptions among tourists from different continents.

Tourists from three continents had different perceptions about corridors, old buildings, overlooks and traffic spaces, reflecting their cultural convention. Asians, Europeans and North Americans diversely gazed at the landscape element of buildings, foliage, sky and people in urban space. All those provided evidence to contribute to the tourist gaze theory's construction.

This study firstly depicted how tourists perceive the tourism symbol of urban space. The novel approach of employing two CV models offer methodological insights to tourism research relevant to visual perception.

La percepción de los turistas del espacio urbano: Un enfoque de vision artificial

Resumen

Los datos para este estudio se extrajeron del conjunto de datos YFCC 100 M. Inicialmente se identificaron nueve tipos de espacio urbano en Pekín mediante un modelo de reconocimiento de escenas. Posteriormente, se aplicó un modelo de segmentación semántica, que aportó pruebas sustanciales en relación con nueve elementos visuales que se utilizaron para suscitar percepciones diferentes entre turistas de distintos continentes.

El objetivo de este estudio es llevar a cabo una investigación empírica sobre las diferentes percepciones de nueve tipos de espacio urbano y nueve elementos visuales entre los turistas en destino, utilizando un enfoque de visión artificial (CV).

Los turistas de tres continentes tenían percepciones diferentes sobre los pasillos, los edificios antiguos, los miradores y los espacios de tráfico, lo que refleja su convención cultural. Los asiáticos, los europeos y los norteamericanos observaron de forma diversa el elemento paisajístico de los edificios, el follaje, el cielo y las personas en el espacio urbano. Todos ellos aportaron pruebas para contribuir a la construcción de la teoría de la mirada turística.

Este estudio describe por primera vez cómo los turistas perciben el símbolo turístico del espacio urbano. El novedoso enfoque de emplear dos modelos de vision artificial ofrece conocimientos metodológicos para la investigación del turismo relacionados con la percepción visual.

This paper aims to answer the following four research questions: Where do tourists gaze at the destination? What do tourists gaze at the destination? How do tourists gaze differently? Why do tourists gaze differently referring to relevant theory?

With a computer vision approach, this study illustrated a series of maps that reflect where and what do tourists gaze at and compared the differences in the visual perceptions among Asian, European and North American tourists in Hong Kong.

The findings confirm that the “tourist gaze” is influenced by geographical and cultural conditions. The conclusions provided three types of implementations for destination management strategies and advocated a high engagement with computer vision technology.

In theory, this study proves that the “tourist gaze” is influenced by geographical and cultural conditions. The study’s methodological contribution lies in applying advanced technology of visual content analysis for big data relevant to the issue of the tourist gaze. Practically, the finding that has not been achieved via previous questionnaire surveys will serve as a reference for tourism recommendations and precision marketing. In addition, its practical contribution is that it offers a means by which to explore tourists’ perceptions of destinations and understand the attractiveness of destinations to tourists.

In this study, the authors demonstrate the inherent connections between bank risk-taking, performance and executive compensation in the banking sector of China by developing a theoretical model and performing empirical tests with simultaneous equation models.

The authors construct a multi-task principal-agent model to capture agency problems in China, and the model can be extended to various cases. In empirical tests, simultaneous equation models are used to examine the theoretical predictions by eliminating endogenous concerns efficiently compared with the methods in the existing literature.

The results indicate that the regulator fails to provide bank managers with positive incentives to control risk, whereas the compensation guidance policy (2010) proposed by the CBRC alleviates this problem in China. Additionally, the authors established that shareholders reward bank managers for better and more stable performance. The authors propose the introduction of restricted stock options into the compensation design, as the existing compensation design fails to balance the performance and risk-taking of banks.

First, the executive compensation structure and details in China are not available. In addition, the equity-based incentive compensation is forbidden. Therefore, this paper cannot provide more details about how the compensation structure affects bank manager behaviours. Secondly, the database consists only 25 listed commercial banks. Luckily, the assets of these banks could account for the vast majority of China's banking assets. The authors also expect that new methodologies such as machine learning and deep learning will be adopted in the research on bank risk management.

First, the regulator should optimise the compositions and payment rule of bank executive compensations. Secondly, it is advisable to adopt restricted deferred share reward or stock option compensation in due course. Thirdly, the regulator can require the banks that undertake excessive risks and troubled by moral hazard to increase the independent director proportion on the bank board according to the authors' empirical tests that higher independent proportion prevents the risk accumulations effectively. Fourthly, except for absolute compensation, the gap between executives' salary and average employee's income should be taken account.

This study provides a theoretical framework that incorporates the manager behaviours, executive compensation and bank regulations, and it provides empirical tests by solving endogenous concerns. Additionally, this study examines the effects of China's compensation guidelines issued in 2010. The authors believe that this study adds value to the existing literature by illustrating the compensation mechanism in China.

The purpose of this paper is to identify the effect of induced capital regulatory pressure on banks’ charter value and risk-taking, and the influence of bank’s charter value on its risk-taking under such a capital regulatory pressure.

The authors use two different estimations to check the robustness of the results. First, they apply a two-stage least squares mode to estimate the impact of capital requirements and bank charter value on bank risk-taking, with the influence of capital regulatory and market-force variables on bank charter value. Second, to reduce the problem of unobserved heterogeneity, the authors use dynamic panel data techniques as a check for robustness.

The empirical results show that higher capital requirements pressure brings about a lower charter value for banks, which in turn increases their risk-taking. The issue of banks’ risk-taking is also affected by their size: large banks seem to be more stable than their smaller counterparts.

The authors’ findings suggest that regulatory pressure has had the desired impact on insolvency risk for Chinese banks due to the expected penalty triggered by a breach of capital requirements.

It is the first paper that investigates the impact of capital regulatory pressure on risk-taking of the Chinese banking system, which sheds light on concerns about regulatory monitoring of bank risk and capital regulatory framework.

This paper measures the impact of capital regulation on Chinese bank charter value and risk-taking and offers some support for the implementation of Basel III in China.

The authors have constructed different measures of regulatory pressure to investigate the influence of new capital regulatory regime on banks’ behavior. Most importantly, the exogenous changes of banks’ capital ratio induced by capital regulatory pressure during the past decade that provides a unique opportunity to directly analyze the impact of capital regulatory pressure on bank charter value and risk-taking.

This paper aims to provide a sensor for fast, sensitive and selective ethylene (C₂H₄) concentration measurements.

The paper developed a sensor platform based on tunable laser absorption spectroscopy with a 3,266-nm interband cascade laser (ICL) as an optical source and a hollow waveguide (HWG) as a gas cell. The ICL wavelength was scanned across a C₂H₄ strong fundamental absorption band, and an interference-free C₂H₄ absorption line located at 3,060.76 cm⁻¹ was selected. Wavelength modulation spectroscopy with the second harmonic detection (WMS-2f) technique was used to improve the sensitivity. Furthermore, the HWG gas cell can achieve a long optical path in a very small volume to improve the time response.

The results show excellent linearity of the measured 2f signal and the C₂H₄ concentration with a correlation coefficient of 0.9997. Also, the response time is as short as about 10 s. The Allan variance analysis indicates that the detection limit can achieve 53 ppb with an integration time of 24 s.

The ethylene sensor has many meaningful applications in environmental monitoring, industrial production, national security and the biomedicine field.

The paper provides a novel sensor architecture which can be a versatile sensor platform for fast and sensitive trace-gas detection in the mid-infrared region.

Drawing on the social cognitive model of career self-management (CSM model) and deep learning theory, the authors' study aims to investigate the effect of knowledge sharing on career adaptability and explore how and when this effect occurs. The authors proposed a moderated sequential-mediation model linking knowledge sharing, knowledge depth, self-efficacy and career adaptability, moderated by reflective thinking.

The authors used a field survey involving 611 employees working in different enterprises in China to test the authors' predictions. For supplementary validation, the authors conducted a scenario-based experiment with a distinct sample of 148 employees from Chinese enterprises. The authors used hierarchical regression analysis, ANOVA analysis and moderated sequential-mediation analysis to test the hypotheses.

The results indicated a positive effect of knowledge sharing on career adaptability, sequentially mediated through knowledge depth and self-efficacy. Additionally, reflective thinking strengthened the positive effect of knowledge sharing on knowledge depth and further moderated the sequential mediating effect.

Previous research has predominantly focused on the perspective that individuals act as “recipients” from the environment in developing career adaptability. Instead, the authors adopt a “giving” perspective by investigating the influence of knowledge sharing on career adaptability, which advances the existing knowledge on the predictors of career adaptability.

The purpose of this paper is to examine the roles of one’s original family and current family in influencing his or her entering entrepreneurial endeavors. Specifically, individuals’ original family is also crucial for entrepreneurship, which has been neglected by prior studies to a large extent. Moreover, the authors argue that a good marital relationship between two parents within the original family could facilitate an entrepreneurial spirit by providing better family support, whereas a good relationship with one’s life partner or spouse within their current family could also increase the likelihood of entrepreneurial activities through reducing work stress.

The authors use two archival data sets: National Longitudinal Survey of Youth 1997 and 2013 Global Entrepreneurship Monitor Adult Population Survey to test whether a harmonious relationship between two parents or with life partner/spouse could encourage individuals to become an entrepreneur and whether family support and work conflict mediate such a relationship.

This study found that parents’ relationship in one’s adolescence provides individuals with more support, which leads to more entrepreneurial endeavors, whereas the conflicts between two parents will reduce their likelihood of initiating entrepreneurial activities. Besides, a good relationship with one’s life partner/spouse can release his/her work stress, which is also important for entrepreneurship development.

Different from the extant related research that focuses more on on-site predictors of entrepreneurship, the current study proposes factors from other life domains, including those in one’s adolescence, that can also influence and change individuals’ choice of entrepreneurial activities throughout their entire life. Harmonious family relationships (i.e. fewer family conflicts) are important for one to start a business, and family conflicts can reduce the likelihood of choosing entrepreneurship as the main occupation.

The purpose of this paper is to propose the complementary design rules, give a quantitative comparison and analyze the force production mechanism of two kinds of primary wound field flux-switching linear (PWFFSL) motors.

PWFFSL motors have the merits of no use of rare-earth magnet, low cost and a wide operation range in which the armature windings and the field windings are all located at the short primary mover and the secondary is very robust. Hence, the PWFFSL motor is ideal for rail transportation systems which need a long stator and a wide speed range. To overcome the disadvantages of the existing PWFFSL motors, new complementary design rules will be proposed. Also, to offer a better PWFFSL motor for the rail transportation systems, it is necessary to investigate different structures of PWFFSL motors and give a comprehensive comparison. To predict the force performance of two kinds of PWFFSL motors with different secondary types, their flux density analysis and force production mechanism will be presented and compared.

The comparison result shows that the PWFFSL motor with toothed secondary can offer larger thrust force, higher force density and higher efficiency, whereas the PWFFSL motor with segmented secondary has the merits of lower force ripple, less use of stator iron, higher power factor and less critical saturation.

Many PWFFSL motors with different primary/secondary pole pitches based on the proposed design principle have not been considered in this paper.

This paper has presented the air-gap flux analysis, proposed the complementary design rules for two kinds of PWFFSL motors with different secondary types and compared the electromagnetic performance of the two motors.

This study aims to build a research model from the perspectives of knowledge hiding and idea implementation to examine what factors influence idea implementation and the cross-level moderating role of team territory climate.

Data were collected from universities, 52 (R&D) teams in China via a two-wave survey. The final sample contained 209 team members and their immediate supervisors. Hierarchical linear modeling was used to test hypotheses.

The results indicated that individuals’ knowledge-hiding behavior had a significantly negative impact on idea implementation and creative process engagement, which played a mediating role. Team territorial climate played a cross-level moderating role between knowledge hiding and idea implementation. If team territorial climate was at a high level, then the negative connection between knowledge hiding and idea implementation would be weaker.

Under the perspective of territorial behavior in Chinese cultural, it can help to distinguish territorial behavior and be preventive at individual and team levels. This study not only enables managers to clearly understand the precipitating factors of idea implementation but also provides constructive strategies for alleviating the negative effects of knowledge territoriality on creative process engagement and idea implementation.

This study constructs a cross-level model to explore the relationship among knowledge hiding, creative process engagement and idea implementation at individual and team levels in the context of Chinese R&D enterprises. Additionally, the study analyzes the influence of territoriality on idea implementation under boundary conditions.

This paper aims to propose that the extent to which activating self-identity increases resource-saving behavior varies across these three levels of self-identities. In particular, the authors hypothesize that activating relational or collective self-identity increases saving behavior more than activating individual self-identity does. Moreover, activating relational self-identity has a stronger impact on workplace saving behavior than activating collective self-identity does. In addition, the authors suggest that prosocial motive mediates the relationship between the three levels of self-identity and saving behavior.

Workplace saving behavior such as office supply savings could help save organizational resources and build more environmentally conscious organizations. Drawing from self-identity theory, the authors examine the influences of three types of self-identities (i.e. individual, relational and collective self-identities) on workplace resource-saving behaviors.

The results obtained from a field experiment conducted in a Chinese company and an online vignette study generally support the proposed hypotheses. The authors also discuss the theoretical and practical implications of the findings.

The authors contribute to the literature on saving behavior in organizations by studying an individual-level predictor from the perspective of self-identity and the research on self-identity and saving behavior by testing the mediating role played by prosocial motive. Based on the findings, the authors also propose some human resource policies to increase workplace saving behavior.
