气候的历史与历史气候研究

寨堡是我国古代重要的军事防御性聚落，其修筑的时间、空间皆与区域的战争形势有着较大关系。清代四川省由于多次大规模战乱，迫使乡民修筑了数以千计的寨堡。寨堡的命名主要可分为因自然地理条件和因人文社会因素两大类，前者包括地形、水文、土石、植物等，后者包括姓氏、寺观、神祇、嘉名、人物、神话、形象、纪事等。寨名包含了丰富的文化内涵，体现出了寨堡的选址、用材、作用、历史、精神等内容。     

Defender–Attacker Games with Asymmetric Player Utilities

The presence of strategic attackers has become an important factor in the security and protection of systems, especially since the 9/11/2001 attacks, and considerable efforts have been dedicated to its study. When defending against the strategic attacker, many existing studies assume that the attacker would seek to minimize the defender's utility, which implies that the defender and attacker have symmetric utilities. However, the attacker's objective is determined by its own valuation of the system and target of the attack, which is not necessarily consistent with the defender's utility. If the attacker unexpectedly targets a different utility, then the defense strategy might no longer be optimal. In particular, the defense strategy could be inferior if the attacker's utility is not known to the defender. This study considers a situation where the defender's utility is the system survivability and the attacker's utility is the expected number of destroyed elements in the system. We investigate possible attack strategies under these two different utilities and compare (a) the conservative defense strategy when the attack utility is unknown to the defender with (b) the optimal defense strategy when the attack utility is known to the defender. We show that the conservative protection strategy is still optimal under asymmetric utilities when the contest intensity is smaller than one.     

Ambidexterity penetration across multiple organizational levels in an aerospace and defense organization

The ambidexterity framework, which comprises two contradictory, yet interrelated processes of exploration and exploitation, has been researched using a variety of perspectives. Few studies, however, provide insight into the question: how is ambidexterity managed across multiple organizational levels? To address this question, we introduce the term ambidexterity penetration that refers to the enactment of ambidexterity across multiple organizational levels and develop a conceptual framework about how it is practiced (horizontally, vertically and organizationally). We empirically showcase this framework using findings from six business units of an aerospace and defense organization and analyzing data from 30 interviews. Overall, our study contributes to ambidexterity research and offers an empirical investigation of ambidexterity penetration across multiple organizational levels in the context of the aerospace and defense sector.     

论近代川边治理与国防安全：从赵尔丰到刘文辉

风云激荡的近代“川边”，历任主政者的川边治理成效殊异：赵尔丰籍“平康三策”，锐意进取，开拓出广阔的川边境域，成功践行“固川保藏”方略。尹昌衡藉个人英雄主义维持短暂的绚烂；其后走马灯式的镇守使无法掌控川边局势，失地溃败；颇具政治韬略的刘文辉，妥善处理民族关系，稳固川边，促使西康成功建省。34年的川边治理为现代西南边疆治理留下了鲜活的经验教训，川滇藏结合部需要新的边疆治理统筹。     

新时代高校国防教育隐性课程开发探究

新时代高校国防教育，在利用好军事理论教学这一显性课程基础上，还需要开发隐性课程。从国防教育隐性课程内涵谈起，阐述了开发国防教育隐性课程的必要性和可行性，进而对高校国防教育隐性课程开发的策略提出了几点看法，认为应该从开发以校园环境建设为基础的隐性课程、开发以制度建设为载体的隐性课程、开发以培育大学精神为核心的隐性课程三方面进行。     

中国国防建设的环境分析

在把中国国防建设的环境分为国际环境和国内环境的基础上,分别分析了中国国防建设的国内外环境的有利和不利因素,认为虽然中国的国防建设环境中存在一定的有利因素,但从整体而言,中国国防建设的环境十分严峻,并且针对此提出了自己的对策、建议。     

论产品责任法中的符合强制性标准抗辩

强制性标准是生产者生产产品必须遵循的标准.符合强制性标准抗辩是指产品符合强制性标准导致伤害时,生产者可减轻或免除赔偿责任.强制性标准与侵权诉讼标准各有千秋,而中国法院对强制性标准的盲目崇拜,使其赋予符合强制性标准抗辩较高的证据效力.法院对强制性标准的尊重实质上是对立法和司法权力的尊重,但这会导致产品符合强制性标准又致害时,受害人无法获得救济.中国法院应适当降低符合强制性标准抗辩的地位,使其既能维护受害人的权益又能鼓励生产者研发新产品.     

Evaluation of the Food and Agriculture Sector Criticality Assessment Tool (FASCAT) and the Collected Data

To protect and secure food resources for the United States, it is crucial to have a method to compare food systems’ criticality. In 2007, the U.S. government funded development of the Food and Agriculture Sector Criticality Assessment Tool (FASCAT) to determine which food and agriculture systems were most critical to the nation. FASCAT was developed in a collaborative process involving government officials and food industry subject matter experts (SMEs). After development, data were collected using FASCAT to quantify threats, vulnerabilities, consequences, and the impacts on the United States from failure of evaluated food and agriculture systems. To examine FASCAT's utility, linear regression models were used to determine: (1) which groups of questions posed in FASCAT were better predictors of cumulative criticality scores; (2) whether the items included in FASCAT's criticality method or the smaller subset of FASCAT items included in DHS's risk analysis method predicted similar criticality scores. Akaike's information criterion was used to determine which regression models best described criticality, and a mixed linear model was used to shrink estimates of criticality for individual food and agriculture systems. The results indicated that: (1) some of the questions used in FASCAT strongly predicted food or agriculture system criticality; (2) the FASCAT criticality formula was a stronger predictor of criticality compared to the DHS risk formula; (3) the cumulative criticality formula predicted criticality more strongly than weighted criticality formula; and (4) the mixed linear regression model did not change the rank‐order of food and agriculture system criticality to a large degree.     

值班律师的角色定位与制度探究

2018年修改的《刑事诉讼法》把值班律师制度作为基本制度规定下来，这是辩护制度的重大突破和进步，法律上对诉讼权利的保障，是反映一国刑事诉讼法治化程度的重要标志之一。值班律师参与刑事诉讼并不当然地具有辩护人的诉讼地位，值班律师的应然定位应当是特殊的法律援助律师。值班律师制度具有推动程序正义实现和促进诉讼效率提升的内在价值，还具有弥补法律援助制度短板、推动审前程序状态合理优化和促进认罪认罚从宽制度良好运行的外在价值。但是，值班律师依然存在一些现实困惑，对这些困惑、问题的破解，正是改善值班律师制度的有效进路。     

以意识形态安全为核心加强高校国防教育

随着习近平总书记提出总体国家安全观，关于国家安全的研究不断丰富和扩大。文化安全作为国家安全的重要保障，意识形态领域的安全又是文化安全的根本要求，高校学生的思维易受外界影响，需要重点教育引导。高校国防教育活动作为意识形态安全教育的主要形式，对于加强国家文化安全有着重要作用。为了切实加强社会主义意识形态安全教育，为国家发展做好文化安全保障，高校国防教育应该从国家安全的高度指导教学，改革教育的内容和方式。
