Extensive numerical simulations on competitive growth between the Edwards–Wilkinson and Kardar–Parisi–Zhang universality classes

Extensive numerical simulations and scaling analysis are performed to investigate competitive growth between the linear and nonlinear stochastic dynamic growth systems, which belong to the Edwards–Wilkinson(EW) and Kardar–Parisi–Zhang(KPZ) universality classes, respectively. The linear growth systems include the EW equation and the model of random deposition with surface relaxation(RDSR), the nonlinear growth systems involve the KPZ equation and typical discrete models including ballistic deposition(BD), etching, and restricted solid on solid(RSOS). The scaling exponents are obtained in both the(1 + 1)-and(2 + 1)-dimensional competitive growth with the nonlinear growth probability p and the linear proportion 1-p. Our results show that, when p changes from 0 to 1, there exist non-trivial crossover effects from EW to KPZ universality classes based on different competitive growth rules. Furthermore, the growth rate and the porosity are also estimated within various linear and nonlinear growths of cooperation and competition.

Construction of University Librarian Team in the Context of Double First-Class Initiative

Data services,knowledge services,and information services are the core service elements of university libraries in the context of the Double First-Class Initiative.Combined with the current situation of insufficient overall service capacity of libraries,this paper proposed strategies and implementation paths for optimizing the service system from three aspects:the construction of the professional qualification system for librarians,the establishment of post institutions,and the construction of library culture.Long-term path:putting library human resource management into the legal track,taking the lead in local legislation,and promoting the construction of library legislation and professional qualification certification system;optimizing the personnel system,implementing hierarchical management and classified assessment for professional librarians and auxiliary librarians.Short-term path:intensive post allocation,namely,assigning the core strength in the core post,and tackling the temporary major work combining multiple forces in the form of a"working group";building an open knowledge service ecosystem,accelerate the cross-border integration of libraries and other organizations,and striving to build the core competitiveness of libraries.

Posttraumatic stress symptom trajectories of Chinese university students during the first eight months of the COVID-19 pandemic and their association with cognitive reappraisal,expressive suppression,and posttraumatic growth

Objective: To identify the moderating effects of cognitive reappraisal(CR) and expressive suppression(ES) on the relationship between posttraumatic stress(PTS) symptoms and posttraumatic growth(PTG) in university students. Methods: The survey included 1 987 Chinese university students who completed questionnaires on PTS symptoms in February 2020, with three follow-up surveys at two-month intervals until August 2020. We assessed CR and ES at February 2020 and PTG at August 2020. Growth mixture modeling was used to classify the PTS symptom trajectories. Multinomial logistic regression was used to recognize the predictors of class membership. The relationships among PTS symptoms, CR, ES, and PTG were examined using multi-group path analysis.Results: Sex, SARS-Co V-2 infection of a family member or friend, number of siblings, CR, and ES were significantly associated with PTS symptoms. Three latent classes were identified: ‘Increasing PTS’(n=205, 10.0%) who had rapid deterioration of PTS symptoms, ‘Moderate PTS’(n=149, 8.0%) who had a high level of PTS symptoms at the beginning and slightly increasing, and ‘Persistent Minimal PTS’(n=1 633, 82.0%), who had slow resolution of PTS symptoms over time. Male, SARS-Co V-2 infection of a family member or friend, and having a lower CR and a higher ES, were more likely to have ‘Increasing PTS’. PTS at February 2020 predicted PTG only in ‘Increasing PTS’ class, and both CR and ES had moderating effects on the conversion between them.Conclusions: Most students recovered from posttraumatic stress of COVID-19 pandemic, but a small proportion expeienced increasing PTS symptoms, and those with this condition may benefit from emotional regulation intervention.

Assessing Growth Parameters from Culm Cuttings of Bambusa vulgaris at the University of Dschang Botanic Garden, West Region of Cameroon: Implications for the Bamboo Resource Base and Rural Livelihoods

Dwindling supplies of bamboo resources and the increase in the demand for bamboo have led to the need for better propagation techniques. This is the only way to ensure the sustainability of the bamboo resource base and improve livelihoods. Thus, this study was carried out to examine the different growth parameters of culm cuttings of Bambusa vulgaris in propagation beds with a substrate consisting of dark soil, manure (compost) and sand in a ratio of 1:1:1. Data on different growth parameters was collected on a daily basis over a three week period and analyzed using appropriate descriptive and inferential statistics. It was found that the different growth parameters (diameter, height, leaves and sheaths) of culm cuttings of B. vulgaris evolved in like manner in three propagation beds. Descriptive statistics for growth parameters of culm cuttings of B. vulgaris showed little or no differences across three shelter/propagation beds (shelter bed 1, shelter bed 2 and shelter bed 3) with 1.4675 ± 1.6172 cm, 93 ± 112 cm, 22 ± 30 leaves, and 4 ± 6 sheaths being the mean diameter, height, number of leaves and number of sheaths for all three propagation beds, respectively. ANOVA test showed no statistically significant variation (p > 0.05) between growth parameters of culm cuttings of B. vulgaris across the three propagation beds, implying that the different growth parameters were relatively similar. Pearson correlation showed the existence of direct and inverse relationships between the different growth parameters of culm cuttings of bamboo. The existence of these direct and inverse relationships could be attributed to the rapid growth rate of bamboo, the substrate used, and the species of bamboo used (B. vulgaris). The study recommends more large-scale propagation projects of this bamboo species in order to ensure the sustainability of the bamboo resource base and improve livelihoods of bamboo dependent rural communities.

Enlightenment of Intelligent Construction in the Construction of First-Class University Campus

In September 2017,the Ministry of Education,Ministry of Finance,and the National Development and Reform Commission jointly announced the first batch of“double first-class”construction universities,aiming to improve China’s education level and strengthen the country’s core competitiveness.In addition to first-class teaching and first-class scientific research,first-class universities should also have first-class campuses.The campus of a first-class university should have a complete range of infrastructure,scale,and function to meet the requirements of school-running and scientific research;it should also advocate sustainable development,which includes the concept of energy-saving,smart,and green.The traditional production methods and management models of the construction industry are far from being able to meet the needs of the construction and development of first-class campuses.Digital,intelligent,and informatized construction models are the only way for current campus construction.

从“外嵌”走向“内生”:高校课程思政深化的实践取径

我国高校课程思政建设在全面深化过程中必须认清实践取径的立场与走势问题。早期课程思政实践取径曾存在“两张皮”或“脱嵌”的问题,其生成逻辑有着特定的观念根源、实践诱因与价值基础。“脱嵌型”课程思政因其立场偏误引发了一系列教育实践风险。新时代高校课程思政实践深化的路向是从“外嵌”走向“内生”,并将由此带来课程思政实践境界提升。而作为内生型课程思政实践取径的现实着力点,包括:重新审视“意识+能力”作为推动课程思政“双核动力”;突破趋同化壁垒,落地落实专业课程分类推进思路,以特色求实效;用大爱照亮课堂“主渠道”,引领课堂教学回归育人本质。

高校教师成长型心智模式对课程思政建设的影响研究

高校教师成长型心智模式由坚定的理想信念、积极开放的思维方式和交融化的专业课程思政知识经验等要素构成。当成长型心智模式缺失时,课程思政建设行为将异化为“伪装型”“机械型”“排斥型”等行为。成长型心智模式的作用机理表现为其构成要素通过影响课程思政认同和自我效能感,进而将课程思政建设的目标确立、能力开发、活动实施等环节有机地整合在一起,形成内在驱动力,促进课程思政建设有效开展,课程思政认同和自我效能感交互影响在此过程中共同发挥桥接作用。因而应加强高校教师成长型心智模式开发,强化课程思政认同,提升其自我效能水平,促使课程思政建设持续有效地推进。

基于FP-growth算法的高校群体性突发事件关联规则分析

为有效预防高校群体性突发事件,借助数据挖掘关联规则挖掘理论,在分析高校突发事件关键诱发因素基础上,构建基于FP-growth算法的高校群体性突发事件关联规则挖掘模型。并将模型应用于事务数据库数据的分析中,研究关键诱发因素间关联关系,实现强关联规则输出。研究结果表明,多数高校群体性突发事件的发生与日期没有必然联系;内部管理因素、内外部突发事件、内部突发事件、政治因素是诱发高校群体性突发事件的主要因素,且外部因素导致的群体性突发事件影响力远远超过内部因素的影响力;当突发事件发生后,应急处置的有效性是决定突发事件影响力的重要因素。

Fuzzy inference systems with no any rule base and linearly parameter growth

A class of new fuzzy inference systems New-FISs is presented.Compared with the standard fuzzy system, New-FIS is still a universal approximator and has no fuzzy rule base and linearly parameter growth. Thus, it effectively overcomes the second "curse of dimensionality":there is an exponential growth in the number of parameters of a fuzzy system as the number of input variables,resulting in surprisingly reduced computational complexity and being especially suitable for applications,where the complexity is of the first importance with respect to the approximation accuracy.

A model for wave growth in fetch-limited conditions

In this paper, it is held that the universal relationships of wave growth in fetch-limited conditions , i. e., (f|~) p=A(x|~)-Band (m|~)0= C(x|~) Dshould satisfy the Toba 3/2 power law and the wave energy balance equation. In the ideal generation situation, theoretically it can be derived that the ideal fetch-limited wave growth relationship should have D=3B and D+B =1, (i.e., B = 0.25, D = 0.75 ) and A3C=2. 1×l(T4C^(1/2)_d , where Cd is the drag coefficient. The 3/2 power law, the wave energy balance equation and the decrease of wave steepness with increasing fetch have became three requirements which should be satisfied by fetch-limited wave growth algorithms. A semi-empirical and semi-theoretical model for fetch-limited wave growth is presented. In the application to the slanting wind situation an un(?)ersal relationship of dimensionless wave energy vs dimensionless peak frequency is presented and the comparisons show that the model is in good agreement with observations.

Invariance of specific mass increment in the case of non-equilibrium growth

The invariance of specific mass increments of crystalline structures that co-exist in the case of non-equilibrium growth is grounded for the first time by using the maximum entropy production principle. Based on the hypothesis of the existence of a universal growth equation, and through the dimensional analysis, an explicit form of the time-dependent specific mass increment is proposed. The applicability of the obtained results for describing growth in animate nature is discussed.

Assessing the Impact of the“Two-child Policy”in China:The Effects of the Second Child on the Growth of Teenagers

Purpose:China’s new universal two-child policy has brought a baby boom of the second child in 2016.With the changing family structures,elder children in adolescence may have more and more emotional and even psycholog­ical problems such as“two-child syndrome”.This paper aims to explore the“influence factors and mechanism of the second child on the growth of teenagers”and has great practical significance to promote the physical and mental health of teenagers and the harmony of two-child families.Design/methodology/approach:By means of literature analysis,in-depth interview,questionnaire survey and statistical analysis,the elder children aged 12 to 18 in the two-child family were taken as the main body of the survey,and an empirical research based on NLP understanding hierarchy theory was carried out.Major Findings:(1)The most significant influence on the growth of teenagers is the attitude of parents,and then the gender of the first child.(2)Parents’favouritism towards the second child would lead to decline in the first child’s academic performance.(3)The higher the family income,the less the influence on the first child’s life.(4)When the age difference is large,the first child and the second child are not easy to have conflicts.Practical implications:Parents should try to treat any children equally.Parents should pay attention to the sibling relationship of their two chil­dren with small age gap.Parents who have two children with a large age gap should properly guide the elder child to help take care of the younger brother or sister.Originality/value:This study contributes to the growing literature focus­ing on the influence factors and mechanism of the second child on the growth of teenagers in the context of China’s new universal two-child policy.It adds some early empirical insights on the physical and mental health of teenagers in two-child families.

高校青年教师时间焦虑感与职业成长的倒U型关系研究——工作旺盛力与成长需求强度的作用

以资源保存理论和情感信息理论为基础,从“增益-损耗”双路径视角出发,对全国11省(市)20所高校的634名青年教师进行问卷调研,考察了高校青年教师时间焦虑感对自身职业成长的影响机制与边界条件。研究发现:时间焦虑已成为青年学界的群体性症候,“青焦”问题亟待关注。超八成受访者具有中度及以上的时间焦虑感,并且在婚姻状况、高校层次、岗位类型和职称级别等方面存在显著差异;时间焦虑感对工作旺盛力具有倒U型影响,并通过工作旺盛力的瞬时中介作用间接对职业成长产生倒U型影响;与此同时,青年教师内在的成长需求强度能够显著调节时间焦虑感与工作旺盛力之间的曲线关系,纾解“过犹不及”效应。
