This study investigated the differences between past and future temporal discounting in terms of neural activity in relation to temporal distance. Results show that brain regions are engaged differently in past and future temporal discounting. This is likely because past temporal discounting requires memory reconstruction, whereas future temporal discounting requires the processing of uncertainty about the future. In past temporal discounting, neural activity differed only when preferences were made between rewards received one hour prior and rewards received further in the past. The peak amplitudes of P2 and P3 varied as the temporal distance increased from 2 weeks to 50 years. In future temporal discounting, neural activity differed only when preferences were evaluated between two delayed rewards. The delay conditions and had a significant influence on P2 and N2. Findings indicate the existence of different decision-making systems operating in past and future temporal discounting

Las críticas de la epistemología social y la teoría de prácticas científicas dePhilip Kitcher se han concentrado en los problemas entorno a su adopciónde la metodología individualista. Señalo en este artículo que, por un lado, elmotivo de Kitcher de adoptar la metodología individualista es para encontraruna epistemología social adecuada, y que, por otro lado, el problema de suadopción de la metodología individualista reside en dos presupuestos: a)existe una distinción tajante entre lo interno, identificado por propiedadesindividuales, y lo externo, identificado por propiedades no individuales,incluyendo las propiedades sociales entendidas como interacciones entreindividuos; b) las normas epistémicas que sirven como razones para establecerel conocimiento tienen que ser internas. Argumento que, si bien el motivo deKitcher es correcto, ambos presupuestos son problemáticos y que la reflexiónsobre ellos exige una nueva perspectiva para analizar los problemas acercade la epistemología social.

Up till now, China has not enacted any legal mechanisms governing certification or supervision for ethics committees. This article analyses deficiencies in the protection of subjects in clinical drug trials under China’s current laws and regulations; it emphasizes that investigators, as practitioners who have direct contact with subjects, play significant roles in protecting and safeguarding subjects’ rights and interests. The paper compares the status quo in China in this area to that of other countries and discusses ways China might enhance the protection of rights and interests of trial subjects, such as enhancing the ethical awareness of investigators through training, improving laws and regulations, and strengthening the communication between investigators and ethics committees.

When fcc single crystals with high-symmetry crystal orientations are deformed to moderate strains by rolling, tension or channel die compression, long dislocation boundaries inclined to the extension axis form. Similarly, long dislocation boundaries are often found in grains embedded in polycrystals deformed in the same manner. These extended planar boundaries are characteristically - 30-40° from the extension direction and contain the transverse specimen axis. The objective of the present article is to demonstrate that EPBs formed during plane strain deformation are parallel to equivalent slip planes, a pair of hypothetical slip systems used for analyses of the strain and crystal rotation components in place of the larger number of physical slip systems. The coincidence of EPBs and equivalent slip plane inclinations is shown to account for persistent observations of EPBs in the angle range - 30-40° from the rolling direction, in rolled single crystals of various initial orientations. The tendency of EPBs towards tilt or twist boundary character can also be rationalized on the basis of the equivalent slip system concept and consideration of the dislocation types available to be incorporated into EPBs

In the philosophy of science, abstraction has usually been analyzed in terms of the interface between our experience and the design of our concepts. The often implicit assumption here is that such interface has a definite identifiable and universalizable structure, determining the epistemic correctness of any abstraction. Our claim is that, on the contrary, the epistemic grounding of abstraction should not be reduced to the structural norms of such interface but is also related to the constraints on the cognitive processes of specific abstractions. This suggests that we should understand abstraction as embodied in different kinds of abstraction practices.

Since their introduction in the early 2000s, the use of social networking websites has exploded. Many businesses are seeing increased revenue due to their social commerce strategy. Despite the popularity of social commerce websites, some consumers are still hesitate to use them. This study aims to evaluate the factors that influence the adoption of social commerce. A sample of 721 Chinese We Chat users took part in the research. The findings reveal that social capital mediates the positive effect of social commerce adoption and perceived ease of use on techno-stress and online impulse purchasing. Likewise, information overloading mediates the positive effect of social commerce adoption and PERU on techno-stress and online impulse purchasing. The findings have implications for both practice and research in understanding social commerce adoption in emerging economies.

The notion of “agent bookkeeping” was proposed when the “Accounting Law of the People’s Republic of China” was updated in 1993. Since their business is specialized in serving small and micro-enterprises, this has created the industry characteristic of generally small in the size of company and low in the salary of employees in Chinese agent bookkeeping companies. Such characteristic results in a series of problems including negative work attitude of employees in the development process, which seriously limit the development of Chinese agent bookkeeping companies. However, issues occurred in the development of agent bookkeeping, such as negative employee attitudes, which severely hampered the growth of Chinese agent bookkeeping companies. Therefore, a model of three dimensions of work attitude has been set up in this paper to demonstrate the working attitude of the staff of the agent bookkeeping companies in China’s Guangdong-Hong Kong-Macao Greater Bay Area, including emotional dimension, behavioral dimension, and cognitive dimension which consists of eight factors: work environment, career satisfaction, interpersonal relationship, role engagement, work vitality, responsibility attitude, emotional identity, and retention attitude. The result indicates that female employees outnumber male ones in agent bookkeeping companies, most employees have a low sense of belonging to the company, limited career development affects employees’ enthusiasm for work, work attitudes are influenced by mediocre work performance among employees with a graduate degree or higher.

Employability is a vital aspect for human development in career fields. In order to explore the factors affecting the employability of finance and trade graduates in higher vocational colleges, the researchers focused on human development in educational settings and conducted a piece of quantitative research within nine higher vocational colleges. The study uses descriptive statistical analysis to demonstrate the sample structure, using t-test, rank sum test, and chi-square test to assess the variables. It also adopts exploratory factor analysis to identify the classification of both educational practice and employability. Then, a multivariable linear regression model was adopted to examine the relationships between three main factors as well as the employability and career development of finance and trade graduates. The findings imply that the soft skills and basic skills of finance and trade college graduates have immensely improved through educational practice; graduates with high motivation for learning could enhance their soft skills and more internships or club engagement brings stronger professional skills. Based on these results, higher vocational colleges, enterprises, policymakers, teachers, and finance and trade graduates will benefit from the findings related to the reform of educational practice for strengthening graduate employability and human development. The originality of this paper is the conceptual evolution of finance and trade college graduate employability, as well as the empirical analysis on educational practice, student engagement, and family background affecting their human development.

The linguistic relativist thesis maintains that there is no neutral ground for different scientific traditions with different theoretic frameworks to communicate rationally, due to the fact that linguistic structure crucially decides the way people think about reality. For quite a long time, historical studies of scientific exchange between East and West have been guided by this thesis. The challenge to this thesis comes from recent studies by Peter Galison, who argues that scientists from different research traditions can communicate rationally in a way similar to the trading exchanges between two countries, in which a local coordination can be reached even if there is a global disagreement about the corresponding word usage in two natural languages. In this paper, I try to show that the concept of trading zone communication provides an interesting and useful theoretical tool to examine how, in the sixteenth, seventeenth, and eighteenth centuries, Chinese scientists communicated with and learned Western knowledge from Jesuit scientists by building local coordination among them. In the first section I introduce the basic ideas of Galison's trading zone theory. In the second section I study the metaphysical, ontological, and epistemological differences between Chinese science and Western science. If the linguistic relativist thesis is taken for granted, these differences are likely to lead many historical studies on Jesuit science in China to reach the relativist conclusion. The third section deals with some of the basic concepts of the trading zone theory to explain how local rational communication among Chinese and Jesuit scientists was built and developed. In the last section I argue that Galison's trading zone theory can help us understand how Chinese scientists learned new knowledge from the Jesuits, especially astronomical and mathematical knowledge, despite the global differences between these two research traditions.

Epistemology of testimony’s map has been charted by identifying the basic controversy between reductionism and non-reductions. John McDowell’s article “Knowledge by Hearsay” (1993/1998) has been taken as a clear example of non-reductionism. This is, however, only partially right. It is correct that, as a non-reductionist, he defends the justifying role that the default position plays in testimonial knowledge. But, his insistence on situating the default position inside the space of reasons suggests that default position should be understood as a kind of reasoning, and that only then evidential reasons can be applied in concrete justifying procedures. This is a very different understanding of the default position from that of classical non-reductionists such as Coady (1992) and Burge (1993, 1997). If McDowell’s epistemology of testimony can be understood in this way, as this paper aims to establish, it should be considered as an attempt tosupersede the reductionist and non-reductionist dichotomy, an attempt that brings a series of reconsiderations of a satisfactory epistemology of testimony.
