Abstract

Purpose

Paediatric congenital esophageal atresia surgery typically requires delicate and dexterous operations in a narrow and confined workspace. This study aims to develop a novel robot assisted surgical system to address these challenges.

Design/methodology/approach

The proposed surgical robot consists of two symmetrical slave arms with nine degree of freedoms each. Each slave arm uses a rigid-dexterous configuration and consists of a coarse positioning manipulator and a distal fine operation manipulator. A small Selective Compliance Assembly Robot Arm (SCARA) mechanism was designed to form the main component of the coarse positioning unit, ensuring to endure large forces along the vertical direction and meet the operational demands. The fine positioning manipulator applied the novel design using flexible shafts and universal joints to achieve delicate operations while possessing a high rigidity. The corresponding kinematics has been derived and then was validated by a co-simulation that was performed based on the combined use of Adams and MATLAB with considering the real robot mass information. Experimental evaluations for the tip positioning accuracy and the ring transfer tasks have been performed.

Findings

The simulation was performed to verify the correctness of the derived inverse kinematics and demonstrated the robot’s flexibility. The experimental results illustrated that the end-effector can achieve a positioning accuracy within 1.5 mm in a confined 30 × 30 × 30 mm workspace. The ring transfer task demonstrated that the surgical robot is capable of providing a solution for dexterous tissue intervention in a narrow workspace for paediatric surgery.

Originality/value

A novel and compact surgical assist robot is developed to support delicate operations by using the dexterous slave arm. The slave arm consists of a SCARA mechanism to avoid experiencing overload in the vertical direction and a tool manipulator driven by flexible shafts and universal joints to provide high dexterity for operating in a narrow workspace.

Abstract

Purpose

The purpose of this study is to restore the spatial distribution of overseas remittance businesses in Shantou during the 1940s. It explores various socioeconomic factors that influenced the concentration of local remittance business investment in real estate. By reconstructing the spatial distribution of remittance business activities in Shantou, this study hopes to lay a foundation for further analysis of the business strategies of Chaoshan merchants.

Design/methodology/approach

This research draws on information from the published Swatow Guide, archival sources and cadastral maps to identify the location of remittance enterprises and the native place and overseas networks of property owners.

Finding

This study reveals that the spatial distribution of the remittance enterprises was determined by the native place origins of local property owners, and that the inflow of overseas Chinese capital contributed to real estate development in Shantou.

Research limitations/implications

Despite the limited access to Chinese official archives, this paper manages to identify several building blocks and neighbors in Shantou for spatial analysis.

Practical implications

This study is the first attempt to use the geographical information system (GIS) method in Chinese urban history research and hopes to establish a larger historical database of Shantou as a sample for comparison.

Originality/value

This investigation advances the spatial study of urban history and overseas Chinese remittances in the maritime society of South China.

Abstract

Purpose

The paper seeks to identify key features of prenatal care utilization and quality in western regions of China and to determine the factors affecting the quality of prenatal care.

Design/methodology/approach

A descriptive, cross‐sectional study was conducted. The instrument for the study was a 10‐stem respondent‐administered, structured questionnaire, designed in Chinese, composed of two segments: general information on infants who were under two years old; and their mothers. The authors determined the quality (both amount and content) of prenatal care using recommendations made by UNICEF and the Chinese Ministry of Health (MOH) jointly for rural areas of China.

Findings

The median number of prenatal visits was three and rate of first trimester visits was 53.6 per cent (n=1,474). Over three quarters (75.3 per cent) of respondents had fewer than five prenatal visits, with this proportion highest in Gansu (95.8 per cent) and lowest in Shanxi (55.4 per cent) provinces. The percentage of women who received qualitatively adequate prenatal care services was only 1.8 per cent. No respondents in Gansu received a completely correct prenatal test, while this rate was 4.0 per cent in Shanxi and 0.2 per cent in Sichuan. Mothers' age (p=0.05), level of educational attainment (p=0.07) and place of prenatal care (p=0.01) were related to the quality of care.

Originality/value

The prenatal care utilization among women in western regions of China is not adequate. Those women who have received prenatal care seldom receive qualitatively adequate prenatal care services, according to national standards. This situation clearly requires urgent attention and improvement.

Abstract

Purpose

The purpose of this study is to integrate network externality and service quality as antecedents to the synthesis of expectation–confirmation model (ECM) and perceived ease of use (PEOU) in explaining customers’ continuance intention of internet-based sharing economy service platforms.

Design/methodology/approach

Sample data for this study were collected from students enrolled in a comprehensive university in Taipei, Taiwan. A total of 600 questionnaires were distributed in various campus locations, and 510 usable questionnaires were analyzed in this study, with a usable response rate of 85.0%. Collected data were analyzed using structural equation modeling.

Findings

The primary findings are as follows. First, service enablers’ online service quality positively affected customers’ perceived usefulness (PU), confirmation and PEOU of internet-based sharing economy service platforms, which directly or indirectly explained customers’ satisfaction and continuance intention of the platforms. Next, service providers’ offline service quality positively influenced customers’ PU of internet-based sharing economy service platforms, which in turn caused customers’ satisfaction and continuance intention of the platforms. Finally, network externality from customers’ side and service providers’ side all positively affected customers’ PU of internet-based sharing economy service platforms, which in turn led to customers’ continuance intention of the platforms.

Originality/value

First, this study contributes to the identification of network externality and service quality that may reveal deep insights to the understanding of customers’ continuance intention of internet-based sharing economy service platforms greatly driven by their confirmation of expectations and satisfaction with the platforms. Next, the empirical evidence on capturing ECM and PEOU for completely explaining the antecedents of customers’ continuance intention of internet-based sharing economy service platforms is well documented. Hence, this study’s findings have significantly shed light on the possible formulation of a richer post-adoption model.

Abstract

Purpose

Recent technological advancements, often linked to Industry 4.0, require organizations to be more agile and innovative. Blockchain technology (BT) holds immense potential in driving organizations to achieve efficiency and transparency in supply chains. However, there exist some insurmountable challenges associated with the adoption of BT in organizational supply chains (SC). This paper attempts to categorically identify and systematize the most influential challenges in the implementation of BT in SC.

Design/methodology/approach

This study resorts to an extensive literature review and consultations with experts in the field of supply chain management (SCM), information technology and academia to identify, categorize and prioritize the major challenges using VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) and Combined Compromise Solution method (CoCoSo).

Findings

The top three classes of challenges revealed in this study are privacy challenges (PC), infrastructure challenges (IC) and transparency challenges (TC). Maintaining a balance between data openness and secrecy and rectification of incorrect/erroneous input are the top two challenges in the PC category, integration of BT with sustainable practices and ensuring legitimacy are the top two challenges in the IC category, and proper and correct information sharing in organizations was the top most challenge in the TC category.

Originality/value

Future scholars and industry professionals will be guided by the importance of the challenges identified in this study to develop an economical and logical approach for integrating BT to increase the efficiency and outcome of supply chains across several industrial sectors.

Abstract

Purpose

By building on cooperation–competition theory, this study aims to investigate the multidimensional flipped effects of neighborhood hotels on Airbnb listings’ popularity, examining the degree to which such impacts are influenced by hotel types and geographical areas.

Design/methodology/approach

This study explores the interdependent and competitive relationship between neighborhood hotels and Airbnb from the perspective of effects on Airbnb listings’ popularity by exploring a data set covering 10,492 Airbnb listings and 2,691 hotels from Ctrip.

Findings

Results reveal that neighborhood hotels’ number of reviews, review ratings and prices each have positive spillover effects on Airbnb listings’ popularity, while quality assurance labels and negative review topic sentiments exert competitive effects on Airbnb popularity. Moreover, the number of budget chain hotels and high-star hotels have positive and negative effects on Airbnb popularity, respectively. Geographical areas also have a moderating effect on the relationship between various hotel-related influencing factors and Airbnb.

Practical implications

This study can offer hotel managers and Airbnb operators a clearer understanding of these businesses’ coexisting relationship. Findings can also provide Airbnb-specific guidelines for practitioners in terms of site selection, promotional features and development strategies for Airbnb listings.

Originality/value

This study establishes a cooperation–competition relationship model between hotels and Airbnb and considers the flipped effects of hotels on Airbnb for the first time. It expands previous studies by considering the multidimensional effects of hotels on Airbnb listings’ popularity and by examining the influences of hotel types and geographical areas on hotels’ impacts on Airbnb.

Abstract

Purpose

This study aims to use a social exchange perspective to investigate the influence of organizational justice on organizational citizenship behavior (OCB).

Design/methodology/approach

Survey and interview data were collected from a sample of insurance firm sales representatives in Taiwan. Structural equation modeling was deployed to explore the relationship between organizational justice, trust, supervisor–subordinate guanxi and OCB.

Findings

The findings offer important theoretical, managerial and social implications for life insurers’ human resource managers.

Practical implications

Organizational justice is a primary influence on OCB, which is connected with the underlying mediating mechanism of trust (trust in supervisor and trust in subordinate) and supervisor–subordinate guanxi (i.e. off-the-job activities).

Social implications

Subordinates can enhance guanxi with their supervisors to create a more harmonious working environment, creating mutual trust. The results suggest that supervisor–subordinate guanxi is based on long-term social exchange. How to balance fairness and efficiency is an import question for decision-makers.

Originality/value

This study’s examination of the role of trust and supervisor–subordinate guanxi in mediating the relationship between organizational justice and OCB expands the organizational behavior literature into a different industry (life insurance) and cultural context (Taiwan).

Abstract

Purpose

The study aims to examine the effects of ulterior motives in peer and expert supplementary online hotel reviews on consumers' perceived deception, dissatisfaction, and its downstream effects on altruistic response and repurchase intentions. The research also examines the moderating role of hotel attribute performance on perceived deception and its consequents.

Design/methodology/approach

This study used convenient non-probability sampling and collected data from 448 inbound tourists in China. It used partial least square structural equation modeling technique and SmartPLS 3.0 for analyzing the main and moderating effects of the variables.

Findings

The ulterior motives in peer and expert supplementary reviews significantly affect perceived deception, further leading to consumers' dissatisfaction and engagement in altruistic response. Noticeably, consumers' dissatisfaction is positively associated with repeat purchase intentions. Hotel attribute performance significantly moderates the relationship between the ulterior motives in supplementary reviews and consumers' perceived deception.

Originality/value

The study examines the key issue in online hotel reviews using the expectancy disconfirmation theory and identifies consumers' altruistic behavior because of their dissatisfaction, contributing to ethics and consumer behavior literature. Moreover, the research offers prolific implications for hotel and travel websites and hoteliers in the study context.
