There is a wide recognition that encompassing an obligation of good faith in every commercial contract is one of the most important advances in contract law in the twentieth century^([1]).Despite the fact that this concept has been incorporated in the vast majority of national legal systems,its precise scope and application may vary from one to another,depending on the commercial traditions and customs of each legal system^([2]).The fact that good faith has been treated differently in different national legal systems has also been reflected on the international level through its inclusion in international legal instruments,one of which is the United Nations Convention on Contracts for the International Sale of Goods(hereafter CISG).In this article,the legislative history of the CISG will be closely examined with the purpose of finding out how a compromise was reached between the common law countries,which expressly objected to the imposition of a duty of good faith,and the civil law countries,which explicitly endorse its incorporation.A logical result flowing from this historical examination,as will be submitted,is that the conceptual ambiguity of good faith is the underlying reasoning behind their fundamentally different attitudes towards the incorporation of this notion in the international commercial context. 展开更多

In order to avoid the worsening of wealth inequality,it is necessary to explore the influencing factors of wealth distribution and discuss measures to reduce wealth inequality.We investigate the wealth distribution in the goods exchange market by using the kinetic theory of rarefied gas.The trading objects are two kinds of commodities(commodities A and B)and the trading subjects are agents of two groups(dealers and speculators).We deduce the interaction rules according to the principle of utility maximization and consider the transfer of agents in the Boltzmann equation.The steady solution of the Fokker-Planck equation for a special case is obtained and the effects of trading strategy and transfer frequency on the steady distribution are analyzed in numerical experiments.The conclusions illustrate that the transfer of agents is conducive to reducing the inequality of wealth distribution. 展开更多

The governance of algorithms is a central issue in the progress on the rule of law in an intelligent society.In the field of copyright law,the allocation of infringement liability for algorithmic recommendation service providers should proceed from a systemic perspective rooted in the rule of law spirit of the times.Moving beyond the principle of technological neutrality and toward the principle of digital for good,it requires exploring the key role of online platforms in preventing infringement and fostering the development of digital technologies for good.This calls for the establishment of a legal system that is conducive to the combination of law and technology to support multi-stakeholder co-governance.It is recognized that algorithmic recommendation service providers bear a higher duty of care under specific conditions than that imposed by the noticeand-takedown process.The determination of whether such providers have fulfilled their duty of care should be based on industry-specific technological advancements,taking into account multiple factors such as the infringement damages,the probability of infringement occurrence,the cost of preventing infringement,and the copyright protection measures already taken in their algorithmic recommendation systems.At the same time,mechanisms such as effective notification,an efficient appeal process,and the right to request content restoration should be established to effectively protect the users'interests. 展开更多

With the continuous promotion of the Belt and Road initiative,the sporting goods manufacturing industry,as a key sector of Chinese enterprises’“going global”strategy,is actively expanding the markets of countries along the Belt and Road.However,there are significant differences in political,economic,and social environments among countries along the Belt and Road,which bring considerable uncertainties to the transnational investment of enterprises.Based on the investment environment of 70 countries along the Belt and Road,this paper constructs a risk evaluation index system including five dimensions:political and legal,economic and financial,socio-cultural,investment environment,and bilateral relations.The Criteria Importance Through Intercriteria Correlation(CRITIC)method is used to determine weight,Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)method is employed to evaluate the investment risks of each country.Furthermore,cluster analysis is used to classify the countries into low,medium,and high-risk levels.Finally,policy recommendations are proposed based on the characteristics of countries with different risk levels,providing decision-making references for sporting goods manufacturing enterprises in selecting suitable countries for investment,enhancing risk prevention capabilities,and improving investment success rates. 展开更多

As a crucial process in the coordinated strikes of unmanned aerial vehicles(UAVs), weapon-target assignment is vital for optimizing the allocation of available weapons and effectively exploiting the capabilities of UAVs. Existing weapon-target assignment methods primarily focus on macro cluster constraints while neglecting individual strategy updates. This paper proposes a novel weapon-target assignment method for UAVs based on the multi-strategy threshold public goods game(PGG). By analyzing the concept mapping between weapon-target assignment for UAVs and multi-strategy threshold PGG, a weapon-target assignment model for UAVs based on the multi-strategy threshold PGG is established, which is adaptively complemented by the diverse cooperation-defection strategy library and the utility function based on the threshold mechanism. Additionally, a multi-chain Markov is formulated to quantitatively describe the stochastic evolutionary dynamics, whose evolutionary stable distribution is theoretically derived through the development of a strategy update rule based on preference-based aspiration dynamic. Numerical simulation results validate the feasibility and effectiveness of the proposed method, and the impacts of selection intensity, preference degree and threshold on the evolutionary stable distribution are analyzed. Comparative simulations show that the proposed method outperforms GWO, DE, and NSGA-II, achieving 17.18% higher expected utility than NSGA-II and reducing evolutionary stable times by 25% in large-scale scenario. 展开更多

This paper studies the evolutionary process of cooperative behavior in a public goods game model with heterogeneous investment strategies in square lattices.In the proposed model,players are divided into defectors,cooperators and discreet investors.Among these,defectors do not participate in investing,discreet investors make heterogeneous investments based on the investment behavior and cooperation value of their neighbors,and cooperators invest equally in each neighbor.In real life,heterogeneous investment is often accompanied by time or economic costs.The discreet investors in this paper pay a certain price to obtain their neighbors'investment behavior and cooperation value,which quantifies the time and economic costs of the heterogeneous investment process.The results of Monte Carlo simulation experiments in this study show that discreet investors can effectively resist the invasion of the defectors,form a stable cooperative group and expand the cooperative advantage in evolution.However,when discreet investors pay too high a price,they lose their strategic advantage.The results in this paper help us understand the role of heterogeneous investment in promoting and maintaining human social cooperation. 展开更多

In the realm of public goods game,punishment,as a potent tool,stands out for fostering cooperation.While it effectively addresses the first-order free-rider problem,the associated costs can be substantial.Punishers incur expenses in imposing sanctions,while defectors face fines.Unfortunately,these monetary elements seemingly vanish into thin air,representing a loss to the system itself.However,by virtue of the redistribution of fines to cooperators and punishers,not only can we mitigate this loss,but the rewards for these cooperative individuals can be enhanced.Based upon this premise,this paper introduces a fine distribution mechanism to the traditional pool punishment model.Under identical parameter settings,by conducting a comparative experiment with the conventional punishment model,the paper aims to investigate the impact of fine distribution on the evolution of cooperation in spatial public goods game.The experimental results clearly demonstrate that,in instances where the punishment cost is prohibitively high,the cooperative strategies of the traditional pool punishment model may completely collapse.However,the model enriched with fine distribution manages to sustain a considerable number of cooperative strategies,thus highlighting its effectiveness in promoting and preserving cooperation,even in the face of substantial punishment cost. 展开更多

Inkjet 3D printing has potential in the additive manufacturing of electronic circuits and devices.However,inks that can be used for printing layers with T5%>300℃ or hardness>200 MPa have been rarely reported.Cyanate ester(CE)polymers have excellent thermal stability,high strength,and low shrinkage compared to other common dielectric inks for inkjet 3D printing,but cannot be quickly shaped by ultraviolet(UV)irradiation or thermal treatment.Combining CEs with UV-curable monomers may be a possible way to accelerate crosslinking,but there are challenges from the adverse effects of the dilution of both monomers.In this study,dielectric inks with acrylate and cyanate moieties were developed.The low viscosity and surface tension of the CE precursor(Bisphenol E cyanate ester)were combined with photocurable acrylate diluent monomers and cross-linker to realize an ink suitable for inkjet 3D printing.An internal dual three-dimensional cross-linked network structure resin was prepared by a combination of photocuring and thermal curing with T5%up to 326.69℃,hardness up to 431.84 MPa,dielectric constant of 2.70 at 8 GHz,and shrinkage of 1.64%.The developed dielectric inks can be applied to the 3D printing of printed circuit boards and other electronic devices that require dielectric properties. 展开更多

Flannery O’Connor is one of the representative figures of American Southern writers.Being recognized as the most outstanding writer of the American South after Faulkner,she has great influence in the literary world.Her works are always shrouded in a strange and grotesque atmosphere and full of death as well as religious metaphors.The protagonists are a series of American Southern freaks struggling with the crisis of spiritual belief.The protagonists of her novel A Good Man is Hard to Find are a hypocritical believer in the world of sinners and a lost man suffering in the midst of real sin,thus O’Connor uses the highest form of violence-death to bring ultimate redemption to them.In people’s conception,violence and redemption are often opposite to each other,but O’Connor uses bloody and violent plots to explore the theme of religious salvation,integrating and unifying the two contrary concepts to form her unique and profound violent redemption writing. 展开更多
