Abstract

Purpose

Encouraging green consumption is a proven strategy for supporting destination sustainability. Nonetheless, extant research approaches destination sustainability mainly from an economic perspective. In this study, we explore the effectiveness of destination social responsibility (DSR) as a way to encourage green consumption among tourists from a social interaction perspective.

Design/methodology/approach

We used a mixed-method approach with two studies (i.e. a scenario experiment and a survey) to test our hypotheses. The scenario experiment included four versions of a narrative scenario with 40 samples each, and 421 valid questionnaires were obtained in the survey.

Findings

Our findings indicate that there is a significant relationship between DSR and green pressure. And DSR positively influences tourists’ green product purchase behavior (GPB). Tourists who have a high fear of negative evaluation (FNE) experience more pressure when exposed to DSR than those with low FNE.

Originality/value

This study sheds light on the mechanisms through which DSR influences tourists’ GPB from a stress transaction perspective and also offers practical implications for tourism marketing and destination management.

Abstract

Purpose

This paper aimed to prepare a kind of ZnS nanoparticles/poly(phenylene vinylene) (PPV) nanofibre and investigate its properties. Because the ZnS nanoparticles are important optoelectronic materials, their incorporation into one-dimensional (1D) nanoscale polymer matrices should be a meaningful subject for electrospinning.

Design/methodology/approach

ZnS/PPV composite nanofibres with an average diameter of 600 nm were successfully prepared by a combination of the in situ method and electrospinning technique. The nanofibres were electrospun from Zn(CH3COO)2·2H2O and PPV precursor composite solution, and the ZnS/PPV fibres were obtained by exposure of the electrospun fibres to H2S gas to prepare ZnS nanoparticles in situ. Such fibres were characterised using X-ray Diffraction (XRD), Fourier transform infrared, transmission electron microscope (TEM), scanning electron microscope and photoluminescence (PL). The photoelectric properties of the fibres obtained were also investigated.

Findings

XRD patterns proved that ZnS nanocrystals generated in the composite nanofibres. The TEM image showed that the nanocrystals were homogeneously dispersed in the nanofibres. The PL spectrum of ZnS/PPV composite nanofibres exhibited a blue shift relative to the PPV nanofibres. I-V curve of the single nanofibre device under 5.76 mW/cm2 light illumination showed that the composite nanofibres have good photoelectric properties.

Research limitations/implications

The comparisons of advantages between ZnS/PPV nanofibres with similar nanofibres will be further expanded in a later research.

Practical implications

Results demonstrate the promise of these novel nanostructures as ultraminiature photodetectors with the potential for integration into future hybrid nanophotonic devices and systems.

Originality/value

The integration of inorganic semiconductor nanoparticles into organic conjugated polymers leads to composite materials with unique physical properties and important application potential. In this work, ZnS nanoparticles were introduced into PPV by an in situ method, so as to obtain a kind of novel 1D nanomaterials with good photoelectric properties.

Abstract

Purpose

This study aims to investigate the relevance of knowledge-oriented leadership (KOL) to technology standard innovation (TSI) from a temporary-team perspective. The mediating and moderating effect on knowledge integration (KI) and leader–member exchange (LMX) is emphasized.

Design/methodology/approach

The conceptual model is built based on an exhaustive literature review and is empirically tested in terms of a sample of 341 Chinese individuals with TSI experience. Quantitative analysis was performed using a questionnaire with the bootstrapping method used to demonstrate the mediating effect of KI.

Findings

The empirical results of this study prove that KI mediates the relationship between KOL and TSI. The authors deduce that LMX moderates the positive relation between KOL and KI.

Originality/value

Few studies have investigated the innovation activities of technology standards from a temporary-team perspective. To the best of the authors’ knowledge, this is the first study to look into the underlying mechanism of KOL in TSI. This research deepens the analysis by introducing LMX’s moderating role in the innovation process of technology standards, thereby providing valuable insights for leaders of innovation activities of technology standards and illuminating new aspects of knowledge-intensive temporary-team management.

Abstract

Purpose

This study aims to explore the effect of innovation ecosystem stability (IES) on innovation performance of enterprises through the mediating role of knowledge acquisition (KA), and to study how these effects are moderated by unabsorbed slack.

Design/methodology/approach

This study draws on data from 327 Chinese enterprises and adopts the multiple linear regression method and bootstrapping method to explore the mediating effect of KA and its moderated mediating effect.

Findings

The results demonstrate that IES is positively associated with innovation performance of enterprises, and KA plays a partially mediating role. Moreover, unabsorbed slack negatively moderates the relationship between IES and KA as well as the mediating effect of KA.

Originality/value

This study investigates the relationship between IES and innovation performance, and the mechanism of influence, which has not been previously studied in the field of innovation ecosystem. This study also examines the interaction between unabsorbed slack and IES and further clarifies the mechanism and boundary conditions of the impact of IES on innovation performance.

Abstract

Purpose

This paper aims to study the oxidation kinetics of the nanocrystalline Al ultrathin films. The influence of structure and composition evolution during thermal oxidation will be observed. The reason for the change in the oxidation activation energy on increasing the oxidation temperature will be discussed.

Design/methodology/approach

Al thin films are deposited on the silicon wafers as substrates by vacuumed thermal evaporation under the base pressure of 2 × 10−4 Pa, where the substrates are not heated. A crystalline quartz sensor is used to monitor the film thickness. The film thickness varies in the range from 30 to 100 nm. To keep the silicon substrate from oxidation during thermal oxidation of the Al film, a 50-nm gold film was deposited on the back side of silicon substrate. Isothermal oxidation studies of the Al film were carried out in air to assess the oxidation kinetics at 400-600°C.

Findings

The activation energy is positive and low for the low temperature oxidation, but it becomes apparently negative at higher temperatures. The oxide grains are nano-sized, and γ-Al2O3 crystals are formed at above 500°C. In light of the model by Davies, the grain boundary diffusion is believed to be the reason for the logarithmic oxidation rate rule. The negative activation energy at higher temperatures is apparent, which comes from the decline of diffusion paths due to the formation of the γ-Al2O3 crystals.

Originality/value

It is found that the oxidation kinetics of nanocrystalline Al thin films in air at 400-600°C follows the logarithmic law, and this logarithmic oxidation rate law is related to the grain boundary diffusion. The negative activation energies in the higher temperature range can be attributed to the formation of γ-Al2O3 crystal.

Abstract

Purpose

FOV splicing optical remote sensing instruments have a strict requirement for the focal length consistency of the lens. In conventional optical-mechanical structure design, each optical element is equally distributed with high accuracy and everyone must have a high machining and assembly accuracy. For optical remote sensors with a large number of optical elements, this design brings great difficulties to lens manufacture and alignment.

Design/methodology/approach

Taking the relay lens in an optical remote sensing instrument with the field of view splicing as an example, errors of the system are redistributed to optical elements. Two optical elements, which have the greatest influence on modulation transfer function (MTF) of the system are mounted with high accuracy centering and the other elements are fixed by gland ring with common machining accuracy. The reduction ratio consistency difference among lenses is compensated by adjusting the optical spacing between the two elements.

Findings

Based on optical system simulation analysis, the optimized structure can compensate for the difference of reduction ratio among lens by grinding the washer thickness in the range of ±0.37 mm. The test data for the image quality of the lens show that the MTF value declined 0.043 within ±0.4 mm of space change between two barrels. The results indicate that the reduction ratio can be corrected by adjusting the washer thickness and the image quality will not obviously decline.

Originality/value

This paper confirms that this work is original and has not been published elsewhere nor is it currently under consideration for publication elsewhere. In this paper, the optimum structural design of the reduction relay lens for the field of view stitching applications is reported. The method of adjusting washer thickness is applied to compensate for the reduction ratio consistency difference of lenses. The optimized structure also greatly reduces the difficulty of lenses manufacture, alignment and improves the efficiency of assembly.

Abstract

China is currently developing and promoting an industrial cluster policy at the government level. By enacting the ‘Opinion on promoting industrial cluster development’, China is supporting the development of industrial clusters. Building an industrial cluster is done by using a single factor but requires many additional factors like regional characteristics, competitiveness factors are also diversified. To evaluate the competitiveness of the Chinese automobile industry cluster, a competitiveness element index should be developed and a competitiveness evaluation method is needed to evaluate the importance of each element. To accomplish this objective, this research applied the analytic hierarchy process (AHP) and focused on the importance of the competitiveness elements.

This research investigated the character is tics regarding cases of clusters and also analyzed the competitiveness of the Changchun automobile cluster located in northeastern China. The purpose of this research is to help Korean enterprises who enter China in the hopes that Korea will emerge as a top automobile production country.

Abstract

Purpose

Owing to multiple superiorities to traditional counterparts, prefabricated construction (PC) has gained increasing attention worldwide. The development of PC projects reflects the effects of both policy supervision and PC practice, which aids the government in reasonably identifying the key issues of PC's promotion and rationally improving the policy deployment. However, existing studies fail to address this aspect, especially lacking quantitative exploration. This study explores the micro mechanism of PC's promotion, from the perspective of developing PC projects.

Design/methodology/approach

A tripartite evolutionary game model based on prospect theory of the government, developers and contractors is constructed. After rigorous theoretical deduction, this study adopts Changchun in China as a case city and collects the data using the Delphi technique, policy documents and literature analysis.

Findings

Results indicate that contractors are generally willing to implement PC projects and the government chooses to actively supervise PC's promotion. The negative investment behavior of developers is the main obstacle to promote PC in Changchun currently.

Practical implications

The conclusions are applicable to other comparable regions. This study is of value to promote PC with high efficiency and effect.

Originality/value

The tripartite evolutionary game model based on prospect theory proposed in this study is conducive to reveal the essence of PC's promotion. This is an important breakthrough in extant studies, with a broad applicability in the PC domain beyond China.

Abstract

Purpose

Internet of Things (IoT), a strategic emerging industry, has brought a new driving force to the global economic growth, as well as an effective solution to break the barrier of economic development. However, standards system of IoT is not yet mature, existing obvious overlapping and even conflicting standards, and enterprises lack mature technology standardization model, which severely restricts the structural upgrading and development of IoT. The paper aims to discuss these issues.

Design/methodology/approach

In this regard, this study combs the research context of the IoT, technology standardization and competition behavior, and analyze technology standardization models of IoT by combining theory with practice. Using game theory and profit function, this paper analyzes the selection mechanism of standardization model of IoT enterprises, and explores practical application of these models using competitive behavior theory.

Findings

First, in the process of standardization, technology standardization model n enterprises is not single, nor is it immutable. Second, the trend of internationalization of technical standards is becoming more and more obvious. Third, if LoT enterprises want to achieve their own technology standardization, the corresponding competitive behavior is essential. Fourth, with the change of innovation capability and market forces, the competitive behavior of enterprises should be improved accordingly to better adapt to the changes of internal and external environment and ensure the realization of the standardization of enterprises. Fifth, if IoT attempts to achieve the same globalization as the internet, there must be a set of support systems.

Originality/value

Finally, some suggestions are given for the future development in the field of IoT. This study will provide some theoretical support for promoting the development of standards and enhancing the competitiveness of IoT enterprises.

Abstract

Purpose

With the development and innovation of IoT technologies, both domestic and international people in the industry believe the development of IoT are the new points of technological innovation and economic growth. But it is becoming more and more prominent that the industries are difficult to connect and the IoT technologies are not standardized. The purpose of this paper is to promote the further development of IoT technology and industry, technology standardization of IoT has become the focus of all concerned parties. Technology standardization, as a technological innovation and development process of the “pruning shears,” has been embedded into the various aspects of innovation activities.

Design/methodology/approach

Based on many previous theories, the authors establish a matrix of the patterns of technology standardization. The authors use the relative state of the highest level of technology of the enterprise and The degree of independent technological innovation as the two dimensions of the model. At the same time, the authors divide the competitive behaviors into two categories and match them with the technology standardization model.

Findings

The authors explain the short-term competitive behaviors in the same enterprise and among different enterprises by using the theories of mutualism and competition among species in biology, and make an analogy between the phenomenon of base pairing in DNA double helix structure and the corresponding relationship of two kinds of innovation abilities and two kinds of competitive behaviors in the process of technology standardization.

Originality/value

Combined with previous theories, explain that innovation capability plays a mediating role in the process in which the combinations of the patterns of technology standardization and competitive behaviors are transformed into the enterprise innovation performance, and the uncertainty of external environment play a regulatory role in the process. Finally, the authors established the final conceptual model for providing theoretical basis for the later research, and put forward the conclusions and prospect at the end of the paper.
