The paper aims to study the effects of the combination of synchronous Web-based teaching with visually creative teaching on art students’ creativity. The twenty-first century is the society of information technology and knowledge-based economy. To cope with the information society, teaching methods would be changed. Traditional chalk and talk can no longer adapt to the changing society. In addition to passing down the tradition, new ideas should also be introduced. In the informational age, the internet becomes an essential living element and synchronous Web-based teaching breaks through the obstacle of space, provides instant and multiple communication channels and creates alternative creativity learning environment.

With experimental design, totally, 208 students in Fujian University of Technology, as the research objects, were led to a 15-week (3 hours per week for total 45 hours) experimental teaching. The study uses analysis of variance for discussing the effect of synchronous Web-based teaching on art students’ creativity and further understanding the effect of the combination of synchronous Web-based teaching with visually creative teaching on art students’ creativity.

The research results show significant effects of synchronous Web-based teaching on creativity, visually creative teaching on creativity and the combination of synchronous Web-based teaching with visually creative teaching on the promotion of creativity.

First, the sample size taken in this study was not large enough to fully reflect the results of the study. The survey sample didn’t cover all the major cities in China, which had a small coverage and couldn’t reflect the research situation of the whole country. Second, the evaluation criteria for artistic students’ creativity were too broad. More specific evaluation rules should be set and the creativity standards should be graded to better guide the implementation of art courses and the cultivation of students’ creativity.

The synchronous Web-based learning environment provides favorable individual thinking space to effectively reduce disturbance among classmates. Synchronous Web-based teaching shares sound, pictures and even films with each other to enrich the learning media. What is more, teachers would be more convenient and fast to deal with materials or handouts or rapidly updating materials and avoiding the loss of handouts.

This paper studied the effects of the combination of synchronous Web-based teaching with visually creative teaching on art students’ creativity, which was a meaningful and innovative topic. And this study can provide more enlightenment and reference for future education.

Periodic inspection of large tonnage vessels is critical to assess integrity and prevent structural failures that could have catastrophic consequences for people and the environment. Currently, inspection operations are undertaken by human surveyors, often in extreme conditions. This paper aims to present an innovative system for the automatic visual inspection of ship hull surfaces, using a magnetic autonomous robotic crawler (MARC) equipped with a low-cost monocular camera.

MARC is provided with magnetic tracks that make it able to climb along the vertical walls of a vessel while acquiring close-up images of the traversed surfaces. A homography-based structure-from-motion algorithm is developed to build a mosaic image and also produce a metric representation of the inspected areas. To overcome low resolution and perspective distortion problems in far field due to the tilted and low camera position, a “near to far” strategy is implemented, which incrementally generates an overhead view of the surface, as long as it is traversed by the robot.

This paper demonstrates the use of an innovative robotic inspection system for automatic visual inspection of vessels. It presents and validates through experimental tests a mosaicking strategy to build a global view of the structure under inspection. The use of the mosaic image as input to an automatic corrosion detector is also demonstrated.

This paper may help to automate the inspection process, making it feasible to collect images from places otherwise difficult or impossible to reach for humans and automatically detect defects, such as corroded areas.

This paper provides a useful step towards the development of a new technology for automatic visual inspection of large tonnage ships.

This study aims to analyze how bed and breakfast (B&B) experience influences customer value cocreation (CVCC) through emotional psychological factors under the social servicescape (SSC).

A moderated chain mediation model was constructed based on the SSC framework. This study collected 722 valid questionnaires through convenience sampling in Xiamen, China, and tourists with B&B experiences were taken as samples. A structural equation model analysis was used to test relevant hypotheses.

Results reveal that B&B experience is the core factor to stimulate CVCC. In this process, the individual emotional psychological factors [pleasant arousal (PAL) and place attachment (PAT)] play the critical chain mediating role. In addition, localness positively moderates the reinforcing effect of B&B experience on PAL and strengthens the positive effect of PAL on PAT.

The findings can provide useful CVCC strategies for B&B operators. They can achieve CVCC by enhancing customer experiences, strengthening emotional interactions and building local culture, thereby improving the competitiveness of B&Bs.

Current research lacks an in-depth analysis on the internal relationship and logic between B&B experience and CVCC, especially from emotional psychological perspectives. To the best of the authors’ knowledge, this study is one of the first studies to reveal the mechanism of the CVCC process of B&Bs under the SSC from an emotional psychological perspective. It provides a new theoretical model for research on the CVCC of experience-dominant logic.

本研究旨在分析社会服务场景下, 民宿体验如何通过情感心理影响顾客的价值共创。

基于社会服务场景框架, 本研究构建了一个有调节的链式中介模型。研究者针对具有民宿住宿体验的游客进行调查, 在中国厦门采用便利抽样技术收集了722份有效问卷, 并采用结构方程模型检验提出的相关假设。

在社会服务场景下, 民宿体验是激发顾客价值共创的核心因素。在此过程中, 个体情感心理因素（愉悦唤醒和地方依恋）发挥了重要的中介作用, 有效衔接了民宿体验到顾客价值共创的实现过程。此外, 地方性是独特的地方文化体验因子, 正向调节了民宿体验对愉悦唤醒的强化作用, 也增强了愉悦唤醒对地方依恋的积极作用。

研究结论为民宿管理者如何提升顾客价值共创贡献了经营策略。民宿管理者可以通过提升顾客体验、加强情感互动和打造地方文化来实现价值共创, 进而提升民宿竞争力。

当前关于民宿体验与顾客价值共创之间的内在关系及逻辑缺乏深入分析, 仍缺乏情感心理视角的探索。本研究首次从情感心理视角揭示了社会服务场景下民宿顾客价值共创的过程机理, 为以顾客体验为主导逻辑的价值共创研究提供了新的理论模型。

Este estudio pretende analizar cómo la experiencia en un B&B influye en la cocreación de valor para el cliente (CVCC) a través de factores psicológicos emocionales en el marco social del servicescape.

Se construyó un modelo de mediación en cadena moderado basado en el marco social del servicescape. En este estudio se recogieron 722 cuestionarios válidos mediante un muestreo de conveniencia en Xiamen, China, y se tomaron como muestra turistas con experiencias en establecimientos Bed and Breakfast (B&B). Se utilizó un análisis de modelo de ecuaciones estructurales (SEM) para poner a prueba las hipótesis pertinentes.

Los resultados revelan que la experiencia en el B&B es el factor central para estimular la CVCC. En este proceso, los factores psicológicos emocionales individuales (excitación placentera y apego al lugar) desempeñan un papel mediador en cadena. Además, el carácter local modera positivamente el efecto de refuerzo de la experiencia de B&B sobre la excitación placentera y refuerza el efecto positivo de la excitación placentera sobre el apego al lugar.

Los resultados pueden proporcionar estrategias de CVCC útiles para los operadores de B&B. Pueden lograr la CVCC mejorando las experiencias de los clientes, reforzando las interacciones emocionales y construyendo la cultura local, mejorando así la competitividad de los B&B.

La investigación actual carece de un análisis en profundidad sobre la relación interna y la lógica entre la experiencia de los B&B y la CVCC, especialmente desde las perspectivas psicológicas emocionales. Este estudio es uno de los primeros que revela el mecanismo del proceso de CVCC de los B&B bajo el modelo social del servicescape desde una perspectiva psicológica emocional. Proporciona un nuevo modelo teórico para la investigación sobre la CVCC en la lógica dominante de la experiencia.

Virtual tourism has become popular in recent years. However, there is still a research gap on virtual tourist motivation. This study aims to identify virtual tourist motivation and explore the relationship between virtual tourism and on-site tourism.

This research identifies virtual tourist motivation based on Means-end chain (MEC) theory. Laddering interviews with 32 respondents were conducted to construct a hierarchical value map. Additionally, a motivation analysis of virtual tourism and on-site tourism was developed based on a review of the relevant literature.

This exploratory study revealed 12 attributes, 9 results and 4 values that virtual tourists wish to achieve and identified 5 means-end chains where self-satisfaction is the most important value-led motivation. Compared with on-site tourism motivations, virtual tourism shows possibilities of replacing, complementing and extending on-site tourism under certain circumstances. However, it significantly depends on whether tourists are attracted by the technical characteristics, security and experience conditions of virtual tourism.

This study contributes to understanding virtual tourist motivation and offers motivation-based insights into the relationship between virtual and on-site tourism. Managerial implications on how to attract potential online tourists are also provided.

虚拟旅游在近些年逐渐受到欢迎。然而, 关于虚拟旅游动机的研究仍存在不足。本研究旨在识别虚拟旅游动机, 并探讨虚拟旅游与现实旅游之间的关系。

El estudio exploratorio reveló 12 atributos, 9 resultados y 4 valores que los turistas virtuales desean alcanzar e identificó 5 MEC en los que la autosatisfacción es la motivación basada en valores más importante. En comparación con las motivaciones del turismo in situ (real), el turismo virtual muestra posibilidades de sustituir, complementar y ampliar el turismo in situ (real) en determinadas circunstancias. Sin embargo, depende en gran medida de si los turistas se sienten atraídos por las características técnicas, la seguridad y las condiciones de experiencia del turismo virtual.

Este estudio contribuye a comprender la motivación del turista virtual y ofrece perspectivas basadas en la motivación sobre la relación entre el turismo virtual y el turismo in situ (real). También se ofrecen implicaciones para la gestión sobre cómo atraer a los turistas potenciales en línea.

To take the advantages of terrain-adaptive capability of legged platform and fast-moving ability of wheeled platform, this paper aims to design a leg-wheel mobile platform for obstacle surmounting and analyze the feasibility and locomotivity of different moving modes.

The platform consists of six leg-wheel units. Each of the units has a close-chain mechanical leg and an actuated wheel at the end of the leg. The platform moves with two modes: legged mode and leg-wheel composite mode. The legged mode achieves high mobility driven by crank motors, while the leg-wheel composite mode achieves obstacle-surmounting ability actuated by crank motors and pitch link motors and obtains high efficiency with the hub motors. The gait planning in different modes has been carried out and the obstacle-surmounting capacity has been analyzed.

Based on the results of kinematic analysis and gait planning of the close-chain leg-wheel platform, the high mobility and efficiency obstacle-surmounting ability are demonstrated with the two movement modes. The feasibility of the design and the performance of the mobile platform is verified with the prototype experiment. The results of this paper show that the platform possesses good obstacle-surmounting capability.

The work presented in this paper is a novel exploration to design a close-chain leg mechanism and with an actuated wheel in series. The close-chain leg mechanism has the advantages of high leg lift and single degree of freedom characteristics, which makes the platform obtain the ability of obstacle-surmounting.

Social media data from financial websites contain information related to enterprise credit risk. Mining valuable new features in social media data helps to improve prediction performance. This paper proposes a credit risk prediction framework that integrates social media information to improve listed enterprise credit risk prediction in the supply chain.

The prediction framework includes four stages. First, social media information is obtained through web crawler technology. Second, text sentiment in social media information is mined through natural language processing. Third, text sentiment features are constructed. Finally, the new features are integrated with traditional features as input for models for credit risk prediction. This paper takes Chinese pharmaceutical enterprises as an example to test the prediction framework and obtain relevant management enlightenment.

The prediction framework can improve enterprise credit risk prediction performance. The prediction performance of text sentiment features in social media data is better than that of most traditional features. The time-weighted text sentiment feature has the best prediction performance in mining social media information.

The prediction framework is helpful for the credit decision-making of credit departments and the policy regulation of regulatory departments and is conducive to the sustainable development of enterprises.

The prediction framework can effectively mine social media information and obtain an excellent prediction effect of listed enterprise credit risk in the supply chain.

Traditionally, each time a new design for a finite impulse response (FIR) filter is required, a new algorithm has to be developed specially for the FIR filter. Furthermore, corresponding hardware architecture must be designed specially to meet the requirement of the FIR specifications. The purpose of this paper is to propose an arithmetic logic unit (ALU)‐based universal FIR filter suitable for realization in field programmable gate arrays (FPGA), where various FIR filters can be implemented just by programming instructions in the ROM with identical hardware architecture.

Rather than multiplier‐accumulator‐based architecture for conventional FIR, the proposed ALU architecture implements the FIR functions by using accumulators and shift‐registers controlled by the instructions of ROM. Furthermore, time division multiplexing access (TDMA) technique is employed to reduce the chip size. In addition, the proposed FIR architecture is verified in a SOC hardware and/or software co‐emulation system.

An ALU‐based universal FIR filter suitable for realization in FPGA is designed and verified in a SOC hardware/software co‐emulation system with example of a 64‐tap FIR filter design.

A software‐based design method as well as TDMA scheme for the ALU‐based FIR filter are introduced, making FIR filter architecture universal, programmable, and consuming less FPGA resources.

The paper aims to contribute to the current research on China's Belt and Road Initiative (BRI) from a historical point of view. The paper investigates why the history of the Silk Roads is important to the BRI, what is in the guiding thought underpinning China's Silk Roads narrative and how this narrative is presented transnationally, through an insightful analysis of the Communist Party of China's (CPC) view of the Silk Roads history, as well as its perception of the connections between the Silk Roads history and the BRI.

The paper sits in the interface between history, heritage and state power. The argument is framed in concepts of historical constructionism and soft power. It is based on the discourse analysis of China's official narrative of Silk Roads and a case study of the planning for the World Heritage nomination of the Maritime Silk Routes (MSR) (China section). The case study is conducted through a qualitative analysis of academic publications, media reports and programs, official speeches and documents that are available to the public in hardcopy or on the Internet.

The paper reveals the relationship between the state-endorsed Silk Roads narrative and the BRI. The paper argues that the state-backed Silk Roads narrative as well as the planning for the World Heritage nomination of the MSR (China section) is guided by the Chinese Communist Party's perception of the BRI. In this respect, the Silk Roads-associated history, heritage and memory are shaped and deployed to serve as a convenient platform for the promotion of the BRI. The Party leaders' perception of the BRI is in large part about the revival of China's past glory, its national rejuvenation and the demonstration of China's soft power.

The paper contributes to the existing literature on the BRI through its enquiries into how the CPC reconcile nationalist ambitions with notions of peace, harmony and cosmopolitanism and how CPC's view of the Silk Roads history shapes its vision of the BRI. The paper examines the role of the state in the construction and articulation of the Silk Roads-associated history, heritage and memory. It investigates how China's official interpretation of the Silk Road heritage serves China's BRI.

The remote sensing data have become the irreplaceable source of data for the regions with little or without rainfall data, but these data also require scientific analysis, correction and application. This paper uses FY-2 rainfall data and the case studies of the droughts occurred in the Weihe River Basin from 2006 to 2009 to monitor the spatial and temporal evolution of climatic droughts. The monitoring results indicate that: (1) Except for 2008 which was a dry year, the other years in the Weihe River Basin had normal dry/wet conditions; (2) From October 2008 to January 2009, the rainfall was significantly reduced across the Weihe River Basin, and the continual rainfall was even less than 1 mm for December and January with a precipitation anomaly percentage lower than -80%, a sign of severe climatic drought. But the rainfall has improved since February 2009, when the precipitation reached 17.8 mm and Pa exceeded 100%, which helped to relieve the stress from drought resistance. A heavy precipitation continued for four months from June to September 2008, with the Pa exceeding 50%; (3) Due to the better temporal and spatial continuity than the ground-based meteorological observation, FY-2 precipitation data have good application prospects in the meteorological drought monitoring at a national or regional macro-scale.

Due to social transformation in China, more than 100,000,000 people are migrating within the country. Many parents are forced to leave their children behind when they migrate. In 2008, 58,000,000 children were living as left‐behind children, mainly in the rural parts of China (Zhang, 2009).Migration and its accompanying stressors may affect the mental health of the left‐behind children. This unique literature review of Chinese literature summarises the present state of knowledge and reviews the influential factors. Possible approaches to intervention and system reforms are discussed.A literature review was performed of published studies between 2001 and 2008. Databases used were Fujian Medical University Library Interface, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP Information. The Chinese word for ‘left‐behind’ was used as a key word. Books, book chapters, monographs and studies on caring were searched electronically and by hand. Altogether, 53 items were found, discussed and grouped together. Migration affected the mental health of the left‐behind children in a passive way, especially their emotions and social behaviour.There is still controversy over how serious mental health problems are among children who have been left behind. Life events, personality, coping strategies and social suppor t can be regarded as four main factors that are predictive of mental health, which provides theoretical guidance for intervention. Suppor t and prevention of mental health problems in schools, in families and in primary care should be developed and studied.
