A new type of internal solitary waves with a re-appearance period of 23 h observed in the South China Sea

The South China Sea （SCS）, in particular the northern SCS, is one of ocean areas where energetic internal solitary waves （ISWs）occur most frequently （Cai et al., 2012; Zheng, 2017）. Based on the re-appearance period （RP） at an observation station, Ramp et al.（2004） divided the ISWs into two types：Type-a and Type-b. Type-a ISWs arrive regularly at the same time every day, i.e., the RP is about 24 h, and Type-b ISWs arrive about one hour late every day, i.e., the RP is about 25 h.

Diversity of New Three-Wave Solutions and New Periodic Waves for the (3 + 1)-Dimensional Kadomtsev-Petviashvili-Boussinesq-Like Equation

Based on the generalized bilinear method, diversity of exact solutions of the (3 + 1)-dimensional Kadomtsev-Petviashvili-Boussinesq-like equation is successfully derived by using symbolic computation with Maple. These new solutions, named three-wave solutions and periodic wave have greatly enriched the existing literature. Via the three-dimensional images, density images and contour plots, the physical characteristics of these waves are well described. The new three-wave solutions and periodic solitary wave solutions obtained in this paper, will have a wide range of applications in the fields of physics and mechanics.

Causes of Corruption in China's Rural Areas in the New Period and Countermeasures

In the new period,corruption in China's rural areas is becoming increasingly prominent. There is frequent occurrence of violation of laws and disciplines,such as the use of power for personal gain,and corruption and bribery. Main causes for the corruption in China's rural areas include imperfect rural supervision mechanism,imperfect financial system,and low crime cost. How to deal with the increasingly serious corruption situation is a topic faced at present and in the future. It is required to continue to reinforce the democratic supervision and education of village cadres,improve the comprehensive quality of villagers,and increase the crackdown and punishment of corrupt practices,so as to guarantee healthy operation of rural authorities.

Palaeoclimatic Cycles, Global Environmental Changes and New Glacial Periods Induced by the Impact of Extraterrestrial Bodies

In terms of Earth\|Sun geometry, the Milankovitch theory has successfully explained most of the cyclic palaeoclimatic variations during the history of the Earth, especially in the Quaternary. In this paper, the authors suggest that the impact of extraterrestrial bodies on the Earth may be another mechanism to cause palaeoclimatic cycles, global environmental changes and new glacial periods. Based on geological and geochemical records in the boundary layers produced by six huge Cenozoic bolide\|impact events (65, 34, 15, 2.4, 1.1, 0.73 Ma B.P.), including those at 34, 15, 1.1 and 0.73 Ma B.P. which are represented by four famous tektite\|strewn fields, the process and mechanics of palaeoclimatic cycles and global environmental catastrophes induced by extraterrestrial impact are discussed in detail. Impact\|generated dust, soot and aerosol floating in the stratosphere could result in short\|term (<1 year), rapid drop in temperature immediately after impact. Through self\|regulation of the Earth’s climate system, the temperature at the surface slowly went up within 100a and maintained stable for a long time at 250K. If there were no other factors leading to the break\|down of the newly\|established equilibrium, a new glacial period would be initiated. Estimating from the thickness of \{δ\{\}\+\{13\}C\} and \{δ\{\}\+\{18\}O\} anomalies in sediments across the impact boundary layer and deposition rate, the duration of two stages of the palaeoclimate cycle in the form of cold weather—greenhouse effect—normal weather was 10\+4-10\+5a, respectively. The conclusion deduced from the above model is supported by palaeotemperature change recorded by oxygen isotope in sediments across the impact boundary layer.

新时期我国农业生产性服务业的创新路径与策略

近年来,我国农业生产性服务业在政策扶持下迅速发展,农业机械装备总量与作业水平持续提升,服务主体与业务范围日趋多元,服务形式不断创新,规模服务主体组织带动农户优势凸显,农业生产性服务的功能作用不断升级。然而,该领域仍面临诸多挑战,如产业仍处于辅助性地位、服务供给不足、机械化作业环节发展不均衡、服务组织数量和融合度不足以及服务短板突出。为应对这些挑战,提出新时期的发展策略:健全工作推进机制;建设公共服务平台,创新农业生产性服务主体合作方式;引导农业生产性服务业规范发展,推动各地建立服务标准;加大政策落实力度,创新农业生产性服务业支持方式;加快培育有实力的服务组织,创新服务供给形式;完善农业基础设施,加快补齐服务短板;切实发挥村集体在推进适度规模经营中“统”的作用。

新时期我国不确定性挑战下的社会政策研究转型

不确定性是人类认识自然与社会能力不足的表现,具有普遍性、相对性与发展性特点。社会科学因其研究对象更加复杂,因而面临的不确定性更大,但迄今为止社会科学在应对不确定性方面还存在明显不足。新时期我国经济社会运行和发展中的不确定性增大,将会给社会政策的运行与发展带来很大的挑战。为此,应该从以下多方面扩展社会政策研究的视角、内容与方法,以应对新的不确定挑战:其一,要进一步突出社会政策研究中的价值引领;其二,进一步重视社会政策的预测性和对策性研究;其三是加强社会政策复杂理论模型研究;其四是提升社会政策研究的动态性视角;其五是进一步加强社会政策学科建设与学科间的交叉与合作。

新时期文论中的改笔现象及其学术史意义——兼谈文艺学的文献学问题

新时期我国文论中尚未引起充分关注的改笔现象,在改写理论日渐引发国际学界关注的今天值得专题探讨。较之于修辞改笔研究,文论改笔研究有基于其自身问题意识和思维逻辑的特殊性。可以从来源改笔、添补改笔、删减改笔、调序改笔、替换改笔、观点改笔与诉求改笔这七方面,对之展开具体的考察和分析。这一过程显示出文论改笔研究的三点学术史意义:使文论的建构性获得权力微观渗透的切片式证明;为文论的引用性注入超越本质主义的当代内涵;从差异与重复中合乎学理地逼迫出文论的独异性。文艺学由此既应顾及显性的静态面上文献,也应重视隐性的动态改笔文献,以求更好地深化和完善自身的文献学维度。

新时期文学批评的方法论变革问题研究

在新时期以来文学批评的发展进程中,20世纪80年代出现的方法论变革是一种重要的批评现象。1985年被称为“方法论年”,其形成是由多种力量推动的。其时,文学批评生态被改造,文学批评话语及话语体系有了新的建构。文学批评的方法论变革在根本意义上是新时期之初文学观念、文学批评理念变化的基本体现,它实现了批评方法从一元到多元的深刻变革,彰显出一种时代性的、难能可贵的理论品格,其与那个时代的文化精神协和一致,表现出鲜明的启蒙、主体性等现代性价值诉求。这一变革有力地冲击了当代中国文学批评的传统模式,开启了新时期文学批评创新发展的新篇章,并为当下文学批评理论探索包括文学批评主体性建设、批评话语与话语体系的建构及文学批评学科意识的持续增强等提供了丰富而宝贵的历史经验。
