This study aims to examine the effects of job crafting on the work engagement of tour leaders mediated by person-job fit and the meaningfulness of work.

Derived from a sample of 331 tour leaders in China, the data for this research were analyzed using partial least squares structural equation modeling.

The findings revealed that job crafting increased tour leaders’ person-job fit and meaningfulness of work, which stimulated their work engagement. Tour leaders’ person-job fit also increased their work engagement and perceptions of the meaningfulness of work. Enhancing the work meaningfulness of tour leaders can significantly increase their work engagement. Person-job fit and meaningfulness of work had a significant mediating effect between job crafting and tour leaders’ work engagement.

Managers need to provide external conditions for tour leaders’ job crafting by expanding structural and social job resources and by creating more stimulating job environments. Managers can enhance tour leaders’ work engagement by shaping their work meaning and person-job fit.

First, this study empirically tested the effects of job crafting on tour leaders’ work engagement, thus directly addressed the lack of academic attention paid to this topic. Second, this study examines the mediating role of person-job fit and meaningfulness of work, with regard to tour leaders’ job crafting and work engagement, based on an integrative concept model.

The study specifically focused on ethical leadership and help seeking during innovation and tested the moderating effect of happiness on the path from help seeking to innovation.

In this longitudinal study, 472 employees from an HR outsourcing company in China participated in the first survey. However, only 184 employees completed two surveys (1 month apart). We used path analysis to test all hypotheses through Mplus.

We found that ethical leadership, through help-seeking, is correlated to innovation. We also found that one’s happiness level is related to innovation, and when employees are chronically happy, the positive effect of help-seeking on innovation is stronger.

Working in an ethical environment, employees are comfortable acknowledging mistakes, hearing feedback and making corrections, which fosters continuous innovation. Conversely, without the influence from ethical leaders, employees may choose to remain silent and abandon continuous innovation due to the concern of losing “face” the context of China.

This paper aims to provide a framework of the supervised hyperspectral classification, to study the traditional flowchart of hyperspectral image (HIS) analysis and processing. HSI technology has been proposed for many years, and the applications of this technology were promoted by technical advancements.

First, the properties and current situation of hyperspectral technology are summarized. Then, this paper introduces a series of common classification approaches. In addition, a comparison of different classification approaches on real hyperspectral data is conducted. Finally, this survey presents a discussion on the classification results and points out the classification development tendency.

The core of this survey is to review of the state of the art of the classification for hyperspectral images, to study the performance and efficiency of certain implementation measures and to point out the challenges still exist.

The study categorized the supervised classification for hyperspectral images, demonstrated the comparisons among these methods and pointed out the challenges that still exist.

The purpose of this paper is to investigate the impacts of equity incentive on stock pricing efficiency, as well as the institutional investors’ response to equity incentive and its role in stock pricing efficiency.

Using a sample of 1,842 companies that announce implementing equity incentive schemes during the period 2009-2018, the authors compare the pricing efficiency between the firms with equity incentive and those without equity incentive, and companies that implement equity incentive before and after the implementation of equity incentive by using multiple regression and propensity score matching -DID (difference in difference) method. In addition, the multiple regression model is built to test the response of institutional investors to equity incentive and its role in the efficiency of stock pricing.

The empirical results indicate that a company’s stock price is influenced more by firm-specific information than systematic factors after it announces a stock-based compensation scheme. Institutional investors respond positively to companies that implement equity incentives. Among the companies that have implement equity incentive, the higher the shareholding ratio of institutional investors, the higher the efficiency of stock pricing.

The authors innovatively establish a connection between the implementation of equity incentive and the operation of stock market. The results imply that besides alleviating the agency problem, equity incentives can also improve the efficiency of stock pricing, which provide empirical evidence to support the positive effect of equity incentive.

The purpose of this study is to provide ideas and theoretical guidance for green, environmentally friendly and efficient “bacteriostasis with bacteria” technology.

In this paper, a beneficial strain of bacteria was extracted and purified from marine mud. Weight-loss test, morphological observation and electrochemical test were used to systematically study the effect of sulfate-reducing bacteria (SRB)-induced corrosion inhibition on X65 steel in simulated offshore oil field production water.

The results showed that a beneficial strain was selected and identified as Vibrio alginolyticus. Under the condition of co-culture of SRB, the average corrosion rate of X65 steel was significantly reduced. In the mixed bacterial system, the surface of X65 steel samples was relatively flat, and the structure of biofilm and corrosion product film was dense. The number of corrosion pits, the average diameter and depth of corrosion pits were significantly reduced. The localized corrosion of X65 steel was significantly inhibited.

The complex and changing marine environment makes the corrosion problem of marine steel increasingly severe, and the microbiologically influenced corrosion (MIC) caused by SRB is particularly serious. The research and development of environmentally friendly corrosion protection technology is a long-term and difficult problem. The use of beneficial microorganisms to control MIC is a green and efficient anticorrosion measure. Compared with terrestrial microorganisms, marine microorganisms can adapt to complex environments, and their metabolites exhibit special biological activities. The use of marine beneficial bacteria can inhibit SRB activity to achieve the corrosion inhibition effect.

The outbreak of the COVID-19 pandemic plunged global tourism into a huge crisis in 2020. China was confronted with a wave of cancellations by tourism consumers due to COVID-19 and tourist complaints rose dramatically during this period. Although tourism enterprises have quickly introduced measures in response, the effectiveness of targeted policies is expected to be evaluated. Concerned about this phenomenon, this study aims to provide insights into the dim prospects of the tourism industry and to bridge the gap between tourists and enterprises.

The current study adopts a two-step method that combines automatic and manual content analysis to contrastively analyse 647 complaints from the Sina platform and the measures of five online travel agencies (OTAs) taken to deal with COVID-19.

The results reveal that the COVID-19-related information and policies issued by official departments had a promoting effect on tourist complaints. OTAs were the main target of complainers, and three themes of complaints were identified, namely, cancellation barriers, refund barriers and customer relationship management. Although tourism enterprises’ policies covered most dimensions of the three themes, more detailed and mutually beneficial policies need to be formulated in the face of a new round of cancellations.

This research attempts to investigate tourism customer complaint behaviours in the case of COVID-19 and to provide tourism enterprises receiving different complaints with practical insights into crisis management. It contributes to simultaneously minimizing business losses and maintaining customer relationships in the service industry, improving the industry’s performance under potential crises in the future.

Información de crisis, estrategias de comunicación y medidas adoptadas ante las reclamaciones de los clientes: el caso de COVID-19

El presente estudio adopta un método en dos fases que combina el análisis de contenido automático y manual para analizar de forma contrastiva 647 reclamaciones de la plataforma Sina y las medidas de cinco agencias de viajes online (OTA) adoptadas para hacer frente a la COVID-19.

El estallido de la pandemia COVID-19 sumió al turismo mundial en una enorme crisis en 2020. China tuvo que hacer frente a una oleada de cancelaciones por parte de los consumidores turísticos debido a la COVID-19, y las quejas de los turistas aumentaron drásticamente durante este periodo. Aunque las empresas turísticas introdujeron rápidamente medidas de respuesta, se espera que se evalúe la eficacia de dichas políticas. Preocupado por este fenómeno, el presente estudio pretende aportar información sobre las sombrías perspectivas de la industria turística y tender un puente entre los turistas y las empresas.

Los resultados revelan que la información y las políticas relacionadas con el COVID-19 emitidas por los departamentos oficiales tuvieron un efecto promotor de las quejas de los turistas. Las OTAs fueron el principal objetivo de los reclamantes, y se identificaron tres temas de reclamaciones: barreras de cancelación, barreras de reembolso y gestión de la relación con el cliente. Aunque las políticas de las empresas turísticas cubrían la mayoría de las dimensiones de los tres temas, es necesario formular políticas más detalladas y mutuamente beneficiosas ante una nueva oleada de cancelaciones.

Esta investigación trata de investigar el comportamiento de las reclamaciones de los clientes turísticos en el caso de COVID-19 y de proporcionar a las empresas turísticas que reciben diferentes reclamaciones una visión práctica de la gestión de crisis. Contribuye a minimizar simultáneamente las pérdidas comerciales y a mantener las relaciones con los clientes en el sector de los servicios, mejorando el rendimiento de la industria ante posibles crisis en el futuro.

As live streaming becomes a widely used online sales mode, previously content-centred anchors are attempting to switch to e-commerce live streaming. The purpose of this research was to explore the mechanisms that prompt consumers to stay or leave after content anchors transfer to live e-commerce broadcasts. In addition, we explored the factors affecting consumption from the perspectives of anchors, consumers and the external environment.

We distributed questionnaires to a group of fans who had experienced the transition of content anchors to live streaming and received back 375 valid questionnaires. Using psychological contract theory, we constructed a theoretical model for the scenario in which content anchors transition to live e-commerce broadcasting and analysed the data using partial least squares structural equation modelling (PLS-SEM).

The results show that circle culture, mainstream culture, initial trust and live streaming content all positively influenced consumers’ attitudes, whilst consumers’ past shopping experiences negatively influenced consumers’ attitudes. The personal charm of the content anchors did not have a significant effect on consumers’ attitudes. Additionally, we found that only anchors with a significant circle culture and good trust levels amongst fans were able to transition to live e-commerce streaming successfully.

This study extends the application of psychological contract theory to the field of e-commerce and describes the transformation of different types of psychological contracts. The paper’s conclusions provide a reference for decision-making and the implementation of transformation by content-based anchors to live streaming, helping them to coordinate their relationships with fans more effectively.

The current review sought to bring light to the issue of an underexplored career phenomenon – career indecision. Career indecision is a significant developmental stage in one’s career life and has been a prominent topic in vocational psychology research in the past decades. However, it has received scant scholarly attention in the human resource development (HRD) field. Besides, the career indecision literature, in general, is lacking theoretical refinement and analytical review. The present study aims to stimulate HRD scholars’ interests by providing an introductory context for understanding the richness and potentialities of researching career indecision in the HRD area.

To address the gap, the author conducted an integrative review (Torraco, 2005, 2016) of 60 peer-reviewed articles and synthesized the existing knowledge of career indecision. More importantly, antecedent and outcome factors associated with career indecision were identified and analyzed.

A nomological network about career indecision was provided. Besides, the results of the integrative review revealed several omissions in the career indecision literature. Building upon that, implications for HRD research and practice are presented and discussed.

As an initial attempt to synthesize career indecision literature, this study sought to stimulate HRD professionals’ interest in examining this underexplored career phenomenon.

This paper is devoted to prepare micro-cone structure with variable cross-section size by Stereo Lithography Appearance (SLA)-based 3D additive manufacturing technology. It is mainly focused on analyzing the forming mechanism of equipment and factors affecting the forming quality and accuracy, investigating the influence of forming process parameters on the printing quality and optimization of the printing quality. This study is expected to provide a µ-SLA surface preparation technology and process parameters selection with low cost, high precision and short preparation period for microstructure forming.

The µ-SLA process is optimized based on the variable cross-section micro-cone structure printing. Multi-index analysis method was used to analyze the influence of process parameters. The process parameter influencing order is determined and validated with flawless micro array structure.

After the optimization analysis of the top diameter size, the bottom diameter size and the overall height, the influence order of the printing process parameters on the quality of the micro-cone forming is: exposure time (B), print layer thickness (A) and number of vibrations (C). The optimal scheme is A1B3C1, that is, the layer thickness of 5 µm, the exposure time of 3000 ms and the vibration of 64x. At this time, the cone structure with the bottom diameter of 50 µm and the cone angle of 5° could obtain a better surface structure.

This study is expected to provide a µ-SLA surface preparation technology and process parameters selection with low cost, high precision and short preparation period for microstructure forming.

This study aims to better understand the morphological characteristics of single particle and the health risk characteristics of heavy metals in PM_2.5 in different functional areas of Handan City.

High resolution transmission electron microscopy was used to observe the aerosol samples collected from different functional areas of Handan City. The morphology and size distribution of the particles collected on hazy and clear days were compared. The health risk evaluation model was applied to evaluate the hazardous effects of particles on human health in different functional areas on hazy days.

The results show that the particulate matter in different functional areas is dominated by spherical particles in different weather conditions. In particular, the proportion of spherical particles exceeds 70% on the haze day, and the percentage of soot aggregates increases significantly on the clear day. The percentage of each type of particle in the teaching and living areas varied less under different weather conditions. Except for the industrial area, the size distribution of each type of particle in haze samples is larger than that on the clear day. Spherical particles contribute more to the small particle size segment. Soot aggregate and other shaped particles contribute more to the large size segment. The mass concentrations of hazardous elements (HEs) in PM_2.5 in different functional areas on consecutive haze pollution days were illustrated as industrial area > traffic area > living area > teaching area. Compared with the other functional areas, the teaching area had the lowest noncarcinogenic risk of HEs. The lifetime carcinogenic risk values of Cr and As elements in each functional area have exceeded residents’ threshold levels and are at high risk of carcinogenicity. Among the four functional areas, the industrial area has the highest carcinogenic and noncarcinogenic risks. But the effects of HEs on human health in the other functional areas should also be taken seriously and continuously controlled.

The significance of the study is to further understand the morphological characteristics of single particles and the health risks of heavy metals in different functional areas of Handan City. the authors hope to provide a reference for other coal-burning industrial cities to develop plans to improve air quality and human respiratory health.
