Rethinking of Teaching Reform of Land Resource Management Discipline in Local Normal Colleges and Universities under the New Situation

The Agriculture and Forestry discipline in local normal colleges and universities plays an important role in cultivating talents and higher education to serve the local"agriculture,rural areas and farmers".The Land Resource Management discipline is a science that studies the use,allocation,and management of land resources and assets,and has comprehensive and practical features.In the context of the proposal of the rural revitalization strategy and the establishment of the Ministry of Natural Resources of the State Council,the importance of cultivating land resource management talents who understands both land planning and urban planning is self-evident,and the teaching reform of Land Resource Management discipline is receiving much attention.Taking the Land Resource Management discipline of Jiangxi Normal University,a key normal university in Jiangxi Province as an example,combining the characteristics of the discipline setting and the development process,we analyzed the existing problems in its development,so as to provide recommendations for the teaching reform of Land Resource Management discipline in local normal colleges and universities.

A Linguistic Perspective of EU＇s Rethinking Education Program and Its Implications

As a key objective of Rethinking Education, multi-linguistic skill is becoming increasingly important for the future European workers as well as the common folks. Being able to communicate in at least one foreign language is considered to be critical for the future talents against EU＇s vast linguistic diversity and increasing integration. It is widely acknowledged that language competence facilitates mobility, employability, active assimilation, as well as personal development of the individuals, especially the young people, therefore, it is given top priority in the Europe 2020 strategy for growth and employment. This paper is intended to explore the strength of the rethinking program from a linguistic perspective and offer some inspirations to domestic foreign language education reform

Rethinking China's Soft Power Building in Africa

Rethinking China's pension reform——The relevance of international experiences

Pension funds remain scarce no matter what institutional design is adopted. China has a host of unique issues facing its pension system,issues that must be confronted; for instance,the disappearance of its demographic dividends and legacy costs incurred due to institutional transition. Such features determine that China’s pension system is merely passable at the present time. In this article,Professor Cai Fang offers new and incisive perspectives on this issue,such as the potential stimulus for economic growth by ageing people’s desire to save money for old-age provisions.

New Development in Global Politics and Rethinking on China's Multilateral Diplomacy

The new developments in global politics exert three systemic impacts on international relations. Global issues, vital to the survival of mankind, rise to the top agenda of national governments. The epicenter of global power is shifting from U.S. and Europe to the rest of the regions. The global "political excitement and zeal" is rolling on. All exact more on the competence of global governance. The current international multilateral mechanisms are in "competence deficit", worsening either in terms of adequacy, validity or legitimacy. The call for the reform of it is ever soaring. China by the way is at once engaging in the multilateral diplomacy transforming the international system and facing the growing pressure of assuming "leadership" and "international responsibility". China needs to continuously adapt to the changed national identity in the multilateral diplomacy, to reconcile the multilateral mechanisms that deal with regions and domains in China's strategic planning and laying-out, to organically associate the short-term and long-term goals and to upgrade the concept of harmonious world in the practice of multilateral diplomacy.

Self-adaptive large neighborhood search algorithm for parallel machine scheduling problems

A self-adaptive large neighborhood search method for scheduling n jobs on m non-identical parallel machines with mul- tiple time windows is presented. The problems＇ another feature lies in oversubscription, namely not all jobs can be scheduled within specified scheduling horizons due to the limited machine capacity. The objective is thus to maximize the overall profits of processed jobs while respecting machine constraints. A first-in- first-out heuristic is applied to find an initial solution, and then a large neighborhood search procedure is employed to relax and re- optimize cumbersome solutions. A machine learning mechanism is also introduced to converge on the most efficient neighborhoods for the problem. Extensive computational results are presented based on data from an application involving the daily observation scheduling of a fleet of earth observing satellites. The method rapidly solves most problem instances to optimal or near optimal and shows a robust performance in sensitive analysis.

Rapid evolution of T2/S-RNase genes in Fragaria linked to multiple transitions from self-incompatibility to self-compatibility

The T2/RNase gene family is widespread in eukaryotes,and particular members of this family play critical roles in the gametophytic self-incompatibility(GSI) system in plants.Wild diploid strawberry(Fragaria)species have diversified their sexual systems via self-incompatible and self-compatible traits,yet how these traits evolved in Fragaria remains elusive.By integrating the published and de novo assembled genomes and the newly generated RNA-seq data,members of the RNase T2 gene family were systematically identified in six Fragaria species,including three self-incompatible species(Fragaria nipponica,Fragaria nubicola,and Fragaria viridis) and three self-compatible species(Fragaria nilgerrensis,Fragaria vesca,and Fragaria iinumae).In total,115 RNase T2 genes were identified in the six Fragaria genomes and can be classified into three classes(Ⅰ-Ⅲ) according to phylogenetic analysis.The identified RNase T2 genes could be divided into 22 homologous gene sets according to amino acid sequence similarity and phylogenetic and syntenic relationships.We found that extensive gene loss and pseudogenization coupled with small-scale duplications mainly accounted for variations in the RNase T2 gene numbers in Fragaria.Multiple copies of homologous genes were mainly generated from tandem and segmental duplication events.Furthermore,we newly identified five S-RNase genes in three self-incompatible Fragaria genomes,including two in F.nipponica,two in F.viridis,and one in F.nubicola,which fit for typical features of a pistil determinant,including highly pistil-specific expression,highly polymorphic proteins and alkaline isoelectric point(pI),while no S-RNase genes were found in all three selfcompatible Fragaria species.Surprisingly,these T2/S-RNase genes contain at least one large intron(>10 kb).This study revealed that the rapid evolution of T2/S-RNase genes within the Fragaria genus could be associated with its sexual mode,and repeated evolution of the self-compatible traits in Fragaria was convergent via losses of S-RNase.

Region coverage control for multiple stratospheric airships with combined self-/event-triggered mechanism

The region coverage control problem of multiple stratospheric airships system is firstly addressed in this paper.Towards it,we propose a two-layer control framework with the artificial potential field(APF)-based region coverage control law and the adaptive tracking control law.The APF-based region coverage control law ensures the coverage task is achieved until every single stratospheric airship ends up performing station keeping where near the respective global minimum point,in which an innovative solution to the local minimum problem is put forward.The adaptive tracking control law is designed to realize motion control using tracking the desired velocity and angular velocity given by coverage control law,with the consideration of several practical control problems as unknown individual differences and external disturbances.To save resources,the combined self-/event-triggered mechanism designed therein significantly reduces the times of state information transmission and control law calculation.The effectiveness of the proposed control framework is verified through simulations.

Performance Study of an FFH/BFSK Self-Normalizing Receiver with Multitone Jamming's Frequency Offsets

This study investigates how frequency offsets of multitone jamming affect the fast frequencyhopped binary frequency shift keying （FFH/BFSK） self-normalizing （SNZ） receiver under additive white Gaussian noise （AWGN）. The average bit-error-rate （BER） expressions of the FFH/BFSK SNZ receiver and the average BER expressions of an FFH/BFSK spread-spectrum （SS） communication system with frequency offsets of multitone jamming for the sake of understanding the simulation results better. Simulation results show that BER performance of the FFH/BFSK SNZ receiver with diversity under the worst case multitone jamming （MTJ） and AWGN suffers from multitone jamming＇s frequency offsets when the jamming power is moderate, which is validated by several simulations with different frequency offsets configured in multitone jamming. Therefore, an FFH/BFSK SNZ receiver under multitone jamming can be combated with the help of frequency offsets of multitone jamming.

曹植《白马篇》创作时间再思考

五言诗《白马篇》是表现曹植理想的代表性诗歌,这首诗通过描写骁勇善战、忠贞报国的游侠儿英雄形象,寄寓了诗人“建永世之业、留金石之功”的强烈渴望。联系曹植的生平及创作经历,以曹丕称帝(220年)为界,明显分为前期、后期两个完全不同的时期。前期作品主要抒发理想与抱负,后期作品主要倾诉自己的不幸遭遇及被压抑的苦闷。因此,《白马篇》就被认为是曹植前期的作品,这是不够恰当的。曹植生活的后期,特别是曹叡统治时期,他的诗文并不仅仅表现苦闷与悲愤,同样具有强烈的建功立业的愿望,如《杂诗》及《求自试表》等。同时,《白马篇》所反映的匈奴、鲜卑叛乱的时间也大致在魏明帝太和四、五年(230-231年)。所以,《白马篇》应为曹植后期的作品。

中国葛兰西研究四十年再思考

葛兰西在继承和发展马克思主义的历程中占据重要地位,其建构的思想体系已成为中外哲学界非常重要的研究议题。中国有关葛兰西思想的讨论肇始于20世纪中后期,历经改革开放后四十余载的发展彰显出鲜明的时代价值与现实意义。通过梳理葛兰西主要哲学思想,回顾相关研究动态发现,中国葛兰西思想研究围绕阐释性研究、比较性研究与当代价值研究三大主题展开,呈现出良好发展态势,收获了丰硕学术成果,但仍存在一些有待改进之处。未来研究需注重葛兰西思想的整体性解读,加强葛兰西思想与中国具体实际的结合,并提升对葛兰西语言学思想的学术关注,以便全面且深入把握葛兰西思想之精髓,规避片面化、碎片化理解。

19世纪法国学院派绘画艺术再认识

在19世纪之前,法国学院艺术几乎拥有决定所有艺术活动的权利,学院美术成为了所有艺术的典范。然而,随着现代工业文明的进步,学院美术逐渐失去了应有的话语权,学院派的沉寂似乎是时代的选择。在19世纪法国绘画革命的波涛汹涌中,学院派画家仍然坚守着“学院”的规则,坚守着前人的传统,同时进行了顺应时代的改变。随着法国美术学院的起源、发展及学院派的沉寂,人们正在透过历史来重新评价和审视19世纪法国学院派艺术。

规律与因果:大数据对社会科学研究冲击之反思——以社会学为例

在社会科学中,大数据研究还刚刚起步,但也取得了一定成果。大数据为社会学和社会科学重新发现社会历史发展规律提供了可能性:它提供了认知宏观社会、检验社会现象的"异质性假设"和"结果稳定假设"的数据基础;它以实时记录的特点较大程度上排除了获取数据时的人为干扰;它将抽样数据中被排斥的极端值重新纳入统计分析。在因果关系上,大数据有助于从根本上克服由于抽样偏颇所引起的样本选择性偏误;匹配数据可以克服或缓解变量遗漏问题;作为面板数据和分层数据,大数据对确定因果效应、检验因果关系比抽样数据更为有利、稳健和可靠。大数据也许可以重构社会学和社会科学的研究目标。

对石漠化概念及其治理的再思考

进一步厘定喀斯特石漠化形成因素对西南喀斯特退化土地生态治理、恢复具有重要意义。梳理当前对石漠化认识有关理论的研究进展,提出喀斯特石漠化是岩溶山地人口增加打破了低土地承载力和低生产力背景下维系的脆弱平衡,而发生的土地退化。当前中国农户正经历着生计转型与多样化生计,对农业生产与农村土地依赖性逐渐减弱,岩溶山地人地关系模型出现了新变化,未来岩溶山地石漠化将呈现由扩展转向收缩的新态势。

中国城镇化道路的反思与对策

改革开放加速了我国的城镇化进程。从1978年至2010年,城镇化率由17.92%迅速提高到49.95%,形成了长三角、珠三角、京津冀三大城市群,一批区域性城市群正在加速形成。城镇化的快速发展特别是城市群的形成为推动我国经济社会发展和增强国际竞争力发挥了重要作用。但与此同时,城镇化也带来了突出的可持续发展问题。主要表现在:人口过度膨胀,城市病集中爆发,经济增长与宜居性背道而驰;城市面貌千篇一律,野蛮拆迁横行,土地型资本运作难以持续;进城易,定居难,城乡"二元社会"问题正演变为城市内定居群体与流动群体"二元社会"问题;城市间恶性竞争,产业同构,建立分工协作的机制任重道远。基于此,本文提出了未来10年推进我国城镇化的对策思路:坚持积极发展小城市和小城镇方针,缓解地域中心城市人口压力;创新农村居民点用地管理制度,实现城镇化与新农村建设有机统一;加强城市规划与管理的科学化,全力提升城市品位;建立跨区域城市协调机制,破解恶性竞争与产业同构困局;促进公共服务均等化,消除新老"二元社会"问题。
