Abstract

Purpose

The purpose of this paper is to investigate the analytical solution of a hyperbolic partial differential equation (PDE) and its application.

Design/methodology/approach

The change of variables and the method of successive approximations are introduced. The Volterra transformation and boundary control scheme are adopted in the analysis of the reaction-diffusion system.

Findings

A detailed and complete calculation process of the analytical solution of hyperbolic PDE (1)-(3) is given. Based on the Volterra transformation, a reaction-diffusion system is controlled by boundary control.

Originality/value

The introduced approach is interesting for the solution of hyperbolic PDE and boundary control of the reaction-diffusion system.

Abstract

Purpose

This paper aims to investigate the investment strategy of a two-sided platform on reducing transaction costs of two user sides and to study the pricing problem of the platform.

Design/methodology/approach

Mathematical derivation is used to compute the optimal decisions of a two-sided platform on pricing and investment. Numerical analysis is used to illustrate the findings.

Findings

It is found that the demand of one user side decreases in the maximal transaction costs reduction to this side but increases in the maximal transaction costs reduction to the other side. It is also found that a platform should never choose the investment in such a way that the maximal transaction costs reductions of two user sides are the same.

Research limitations/implications

Several limitations exist in this paper, most of which exist due to the assumptions. These limitations could be good research directions in the future. For example, only one platform’s decision is considered, and platforms’ competition is not taken into account. Considering other platforms’ competition, the decisions of the users and the platform would be different.

Originality/value

From the transaction costs perspective, this paper finds that a platform should never choose the investment in such a way that the maximal transaction costs reductions of two user sides are the same. This conclusion has not been found in previous literature.

Abstract

Purpose

By studying the competition between a B2C platform and a third-party seller, the purpose of this paper is to analyze and compare their optimal decisions and profits between cases with and without sales effort of the platform or third-party seller.

Design/methodology/approach

This paper studies the competition between a B2C platform and a third-party seller. The platform sells a product directly, and allows the third-party seller to sell a competing product on the platform. Based on whether the platform or the third-party seller makes sales effort, there are four scenarios. The paper analyzes the optimal decisions and profits of platform and third-party seller under each scenario, respectively.

Findings

The transaction fee has a negative effect on third-party seller’s sales effort level. What is more, the platform can take a free riding from the third-party seller’s sales effort, but the platform’s sales effort has a negative effect on the profit of third-party seller.

Practical implications

These results provide managerial insights for the platform and the third-party seller to make decisions.

Originality/value

This paper is among the first papers to study the competition between B2C platform and third-party seller.

Abstract

Purpose

The purpose of this paper is to introduce the background and significance of criminalization of self-money laundering in China and to analyze its application in judicial practice.

Design/methodology/approach

This paper introduces the international and domestic background of the criminalization of self-money laundering, demonstrates the theoretical basis and practical significance of the changes of Article 191 in the 11th amendment to the criminal law and puts forward solutions to some controversial issues in judicial practice.

Findings

The 11th amendment to the Criminal Law, which came into force in March 2021, criminalizes self-money laundering under Article 191 and has brought an impact on the traditional theory of criminal law. There are no similar amendments to the other two crimes, namely, Article 312 and Article 349, which lead to some confusion in the judicial practice, especially in the understanding of the number of crimes, and the meaning of proceeds of crime. This paper puts forward solutions to some controversial issues in judicial practice.

Originality/value

This paper introduces the criminalization of self-money laundering in the 11th amendment to the criminal law in China, presents a comprehensive description of and comments on the difference between the Article 191 and its similar articles, namely, Article 312 and Article 349, to make a well understanding in the application of law in judicial practice, which would be beneficial to theoretical researchers and judicial professionals.

Abstract

Purpose

The purpose of this paper is to provide the foundational economics, both in theory and practice, to describe the current competitive and operational market dynamics of the blood service industry in the United States of America.

Design/methodology/approach

The paper applies the dominant firm-competitive fringe model to describe how pricing is determined within the blood service industry, with particular focus on the nonprofit business model. The research also describes the role of government as one of the major determinants of pricing through regulatory demands.

Findings

The longstanding, free-market based economic foundations of the blood service industry have proven to be adequate in meeting the blood needs of the United States (US). Though there are clear market inefficiencies associated with the dominant firm model, none of the proposed solutions target the contractual and resulting pricing inefficiencies that persist because of the market structure.

Originality/value

In order to add value to the blood industry professionals, it is imperative to provide the foundational economics driving the current macro-level blood industry of the US.

Abstract

Purpose

The purpose of this paper is to study the effect of doping, annealing temperature and visible optical excitation on CuO-ZnO nanocomposites’ acetone sensing properties and introduce an attractive candidate for acetone detection at about room temperature.

Design/methodology/approach

ZnO nanoparticles doped with CuO were prepared by sol-gel method, and the structure and morphology were characterized via X-ray diffraction, scanning electron microscope, energy dispersive spectroscopy and Brunauer-Emmett-Teller. The photoelectric responses of CuO-ZnO nanocomposites to cetone under the irradiation of visible light were investigated at about 30°C. The photoelectric response mechanism was also discussed with the model of double Schottky.

Findings

The doping of CuO enhanced performance of ZnO nanoparticles in terms of the photoelectric responses and the gas response and selectivity to acetone of ZnO nanoparticles, in addition, decreasing the operating temperature to about 30ºC. The optimum performance was obtained by 4.17% CuO-ZnO nanocomposites. Even at the operating temperature, about 30ºC, the response to 1,000 ppm acetone was significantly increased to 579.24 under the visible light irradiation.

Practical implications

The sensor fabricated by 4.17% CuO-ZnO nanocomposites exhibited excellent acetone-sensing characteristics at about 30ºC. It is promising to be applied in low power and miniature acetone gas sensors.

Originality/value

In the present research, a new nanocomposite material of CuO-ZnO was prepared by Sol-gel method. The optimum gas sensing properties to acetone were obtained by 4.17% CuO-ZnO nanocomposites at about 30ºC operating temperature when it was irradiated by visible light with the wavelength more than 420 nm.

Abstract

Purpose

The purpose of this research is to synthesize Al2O3-ZnO thick films, study the effect of doping and optical excitation on their sensing properties and introduce an attractive candidate for acetone detection in practice.

Design/methodology/approach

ZnO nanoparticles doped with Al2O3 were prepared by sol-gel method and characterized via X-ray diffraction and field-emission scanning electron microscopy. The sensing properties to acetone were investigated with an irradiation of UV. The sensing mechanism was also discussed with UV-Vis spectroscopy.

Findings

The doping of Al2O3 promoted the sensing response and stability of ZnO nanoparticles. The optimum performance was obtained by 4.96 Wt.% Al2O3-ZnO. The response to acetone (1,000 ppm) was significantly increased to 241.81, even just at an operating temperature of 64°C. It was also demonstrated that optical excitation with UV irradiation greatly enhanced the sensing response and the sensitivity can reach up to 305.14.

Practical implications

The sensor fabricated from 4.96 Wt.% Al2O3-ZnO exhibited excellent acetone-sensing characteristics. It is promising to be applied in low power and miniature acetone gas sensors.

Originality/value

In the present research, the optimum performance was obtained by 4.96 Wt.% Al2O3-ZnO at a low operating temperature of 64°C. The sensing properties were enhanced significantly with optical excitation, and the sensing mechanism was discussed with UV-Vis spectroscopy which has been reported rarely before.

Abstract

This chapter draws from a three-year ethnographic study focused on the educational and community interactions among working- and middle-class ethnic Chinese immigrants in a mid-western town in the United States. Aihwa Ong (1999) argues that “Chineseness” is a fluid, cultural practice manifested within the Chinese diaspora in particular ways that relate to globalization in late modernity, immigrants’ cultural background, their place in the social structure in their home society, and their new social class status in the context they enter. The study extends research focused on the complexities of social reproduction within larger global flows of Chinese immigrants. First, we describe how Chinese immigrants’ social status in their countries of origin in part shapes middle and working-class group’s access to cultural capital and positions in the social structure of their post-migration context. Second, we trace groups’ negotiation of their relational race and class positioning in the new context (Ong, 1999) that is often invisible in the processes of social reproduction. Third, we describe how both groups must negotiate national, community, and schooling conceptions of the model minority concept (Lee, 1996) that shapes Asian-American’s lived realities in the United States; yet the continuing salience of their immigrant experience, home culture, and access to cultural capital (Bourdieu, 2007) means that they enact the “model minority” concept differently. The findings suggest the complexity of Chinese immigrants’ accommodation of and resistance to normative ideologies and local structures that cumulatively contribute to social reproduction on the basis of class.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.
