Research on Key Influencing Factors and Willingness of “Slow Employment” of College Students

After years of expanding the enrollment of college students in China, a large number of college students graduate every year. Starting from 2022, the number of college graduates will exceed 10 million, and both the society and universities are faced with the problem of how to arrange the employment of college graduates. The phenomenon of delayed employment of college graduates has gradually become a “slow employment” problem studied by scholars. Through the investigation of internal and external influencing factors such as society, school, family and individual, this paper finds that the external factors of family and internal factors of income expectation are the key factors leading to the “slow employment” intention of undergraduate college graduates. The corresponding discussion and suggestions are given

Analysis on the Construction Path of “Golden Course” of International Commercial Law in International Trade Major from the New Liberal Arts Perspective

Under the background of “new liberal arts”, curriculum innovation and development become an important way to improve the quality of talent training. Therefore, the construction of “golden course” as a breakthrough is the focus of talent training and professional development in undergraduate colleges. Based on the analysis of the necessity of constructing the “golden course” of International Commercial Law in international trade major from the perspective of new liberal arts and the existing problems in course construction, this paper constructs the “five-in-one” teaching mode of “Golden Course” of International Commercial Law in international trade major by combining the teaching idea of “pre-class + after-class + in-class”, and explores the cultivation path of foreign trade law compound talents. To cultivate high-quality practical foreign trade talents who meet the needs of the construction of a trade power and the development of the country and society

Total Nuclear Reaction Cross Section Induced by Halo Nuclei and Stable Nuclei

We develop the method for the calculation of the total reaction cross sections induced by the halo nuclei and stable nuclei. This approach is based on the Glauber theory, which is valid for nuclear reactions at high energy. It is extended for nuclear reactions at low energy and intermediate energy by including both the quantum correction and Coulomb correction under the assumption of the effective nuclear density distribution. The calculated results of the total reaction cross section induced by stable nuclei agree well with the 30 experimental data within 10 percent accuracy.The comparison between the numerical results and the 20 experimental data for the total nuclear reaction cross section induced by the neutron halo nuclei and the proton halo nuclei indicates a satisfactory agreement after considering the halo structure of these nuclei, which implies the quite different mean fields for the nuclear reactions induced by halo nuclei and stable nuclei. The halo nucleon distributions and the root mean square radii of these nuclei can be extracted from above comparison based on the improved Glauber model, which indicate clearly the halo structures of these nuclei. Especially, it is clear to see that the medium correction of the nucleon-nucleon collision has little effect on the total reaction cross sections induced by the halo nuclei due to the very weak binding and the very extended density distribution.Comment: 15 pages,2 figures.

PLLA-PEG-TCH-labeled bioactive molecule nanofibers for tissue engineering

By mimicking the native extracellular matrix, electrospun nanofibrous scaffolds (ENSs) can provide both chemical and physical cues to modulate cell adherence and differentiation and to promote tissue regeneration while retaining bioresorbable and biocompatible properties. In this study, ENSs were developed to deliver multiple biomolecules by loading them into the core-sheath structure and/or by conjugating them to the nanofiber surfaces. In this work, poly(L-lactide)-poly(ethylene glycol)-NH2 and poly(L-lactide) were emulsion electrospun into nanofibers with a core-sheath structure. A model drug, tetracycline hydrochloride, was loaded within the nanofibers. Amino and carboxyl reactive groups were then activated on the fiber surfaces using saturated water vapor exposure and base hydrolysis, respectively. These reactive groups allowed the surface of the ENS to be functionalized with two other bioactive molecules, fluorescein isothiocyanate- and rhodamine-labeled bovine serum albumins, which were used as model proteins. The ENSs were shown to retain their antimicrobial capacity after two functionalization reactions, indicating that multifunctional nanofibers can potentially be developed into functional wound dressings or periodontal membranes or used in more complicated tissue systems where multiple growth factors and anti-infection precautions are critical for the successful implantation and regeneration of tissues
