García Márquez’s Impact and Mo Yan’s Magical Realism

Mo Yan is an important representative of Chinese root-searching writers.Though born in different cultural background, García Márquez’s magic realism style greatly impacts Mo Yan’s literary creation. In displaying various aspects of Chinese people’s character and social life, Mo Yan merges folk tales, history and the contemporary, and constructs his unique magic realism with oriental characteristics

A Deep Dive into Blockchain Selfish Mining

This paper studies a fundamental problem regarding the security of blockchain on how the existence of multiple misbehaving pools influences the profitability of selfish mining. Each selfish miner maintains a private chain and makes it public opportunistically for the purpose of acquiring more rewards incommensurate to his Hashrate. We establish a novel Markov chain model to characterize all the state transitions of public and private chains. The minimum requirement of Hashrate together with the minimum delay of being profitable is derived in close-form. The former reduces to 21.48% with the symmetric selfish miners, while their competition with asymmetric Hashrates puts forward a higher requirement of the profitable threshold. The profitable delay increases with the decrease of the Hashrate of selfish miners, making the mining pools more cautious on performing selfish mining.Comment: 6 pages, 13 figure

The Value Orientation of Teaching Reform in the Era of Smart Education

Based on the influence of the era of smart education on education and teaching, this article discusses the humanistic, social, cultural, and practical rationality of teaching reform in the era of smart education from the development trend of the integration of teaching reforms and information technology. Grasping the theoretical basis of teaching reform under the background of the new era will play a proper guiding role in the practice of teaching reform

IMPORTANCE AND PERFORMANCE ANALYSIS OF DISTANCE EDUCATION FOR RADIO AND TELEVISION UNIVERSITY OF CHINA STUDENTS IN CHINA

This study aims to measure students’ perception on importance and performance of Radio and Television University of China (RTUC), with intention to help improve the university’s business. Student satisfaction is one of the important indexes of university ranking, and it is also an important reference index when students choose university. As a radio and television university, its students are mainly adults who have entered the social work, students in order to be more competitive in the workplace to promote the continuing education of academic qualifications. Unlike full-time students who are influenced by a variety of factors, adult students will focus on student satisfaction when choosing a school, so improving college satisfaction is important for RTUC enrollment, and studying the impact criteria of different variables on student satisfaction can help RTUC improve student satisfaction and thus better help universities attract students to enroll. Variables effecting RTUC’s students’ satisfaction in the distance education industry of china includes eight attributes: they are, RTUC’s general service, registration guide, tutorial, practice, learning material, examination, media, and, cost/value for money. Survey conducted on RTUC’s 401 students via questionnaire of 44 questions finds no significant difference between their perceptions on importance and performance of all variables. This is a  research use quantitative method and use important and performance analysis to evaluate the result

Do Loyal Customers Pay More in Live Streaming?

With the rise of the live streaming industry, streamers are facing stiff competition. While there is a common perception that loyalty generates more profits for the firm, there is also conflicting evidence that loyal customers may not be charged more. The live streaming context provides an ideal setting to empirically examine the value of loyal customers and offers a new dimension for measuring behavioral loyalty. Our results suggest that customers with higher consumption loyalty generally pay less while those with higher social loyalty tend to voluntarily pay more. Moreover, there is a crowding-out effect for the same type of resources and a compensation effect between different types of resources concerning the relationship between historical and current inputs. Theoretical explanations drawn on the social exchange theory and practical implications are discussed

The Gamma Deposition Matrix Method for Coupled Neutron-gamma Reactor Heating Calculations

This thesis concerns the development of an approximate model to predict the energy deposited by gammas following a gamma-release reaction in a light water reactor. This approximate model is an alternative method to the conventional approach of solving the gamma transport equation. Although explicitly solving the gamma transport equation has become possible in recent years thanks to advancements in computing power, it is desirable to come up with a simpler method given the fact that gammas only account for ~10% of energy deposition in LWRs. The new method, called the gamma deposition matrix (GDM) method, calculates gamma energy deposition for coupled (n,γ) iterations without performing an explicit gamma transport calculation. Entries of the GDM represent the gamma energy deposited in a given spatial cell due to a gamma source in another (or the same) spatial cell. The GDM can be pre-calculated based on a gamma deposition Green's function, which allows gamma energy deposition to be directly computed from the known gamma source by using the GDM to perform a simple matrix-vector multiplication. A significant advantage of the GDM method is that since gammas mainly interact with electrons, gamma cross sections are independent of temperature and depletion. As a result, the GDM is insensitive to thermal feedback and isotopic changes due to depletion, allowing the initial GDM to be used for all (n,γ) iterations throughout a reactor cycle. Through coupled (n,γ) calculations in MPACT, it is shown that the gamma source spectra do not change over coupled (n,γ) iterations in an LWR. This observation, combined with the fact that the gamma energy deposition is integrated over all gamma energies, leads to the conclusion that the GDM is not a function of gamma energy, resulting in a substantial reduction in the size of the GDM. However, in principle the spatial dependence of the GDM can be prohibitive because the GDM is non-zero for any combination of source and target cells, leading to a huge GDM for full core calculations. In order to further reduce the size of the GDM, the spatial range of the GDM is reduced by neglecting the energy deposition outside a given distance from the source cell. This active region is called a subdomain and the GDM entries are only non-zero for those cells in the subdomain surrounding the source cell. This subdomain model reduces the size of the GDM substantially, with a corresponding reduction in GDM computation time and memory. Since gammas that escape from the subdomain without interaction will result in a loss of energy, an energy preservation scheme is developed that ensures conservation of gamma energy. Numerical results calculated using the energy-independent GDM with the subdomain approximation agree well with reference Monte Carlo calculations. The subdomain approximation is proved to be especially beneficial for large cases. For a small modular reactor whole core case with 37 assemblies and 289 pins within each assembly, using the subdomain approximation along with the energy preservation correction reduces the size of the matrix by ~20 while maintaining satisfactory accuracy.PHDNuclear Engineering & Radiological SciencesUniversity of Michigan, Horace H.

Application of Formative Assessment in College English Teaching

A comprehensive, objective, scientific and accurate evaluation system is a key component in College English teaching. On the one hand, it helps the students to obtain feedback to adjust their learning strategies in order to improve their learning efficiency. On the other hand, it provides the teacher with information to better achieve the teaching goal and ensure the teaching quality. The formative assessment is in nature a procedural evaluation that aims to cover the whole growth and progress of a student in learning a specific course, to provide an accurate judgment on whether and to what extent the students have achieved their learning objectives from various aspects. It facilitates the effective monitoring of students’ autonomous learning, and is particularly important in the college English teaching. This article makes an analysis on the characteristics of formative assessment, points out the principles in implementing formative evaluation and discusses the specific approaches to applying formative assessment in the college English teaching
