后人文语境下美国科幻小说对"人"的书写 ——以"沙丘三部曲"为例

科幻叙事集科学元素和幻想成分于一身,与后人类想象紧密结合.从美国科幻文学学术史出发,回溯美国科幻小说对"人"的审视和书写,可以发现其从纯粹地维护人类主体性转向反思批判人类中心主义的创作流向.以弗兰克·赫伯特(Frank Herbert)的"沙丘三部曲"为例,解读作品对人与科技、人与自然、人与生物三种关系的后人类构想,从而探索美国科幻小说有关"人"的书写怎样预示了超前的后人类境况,以及这种境况所带来的对于后人类社会中伦理问题的思考.

A quadratic time exact algorithm for continuous connected 2-facility location problem in trees

This paper studies the continuous connected 2-facility location problem (CC2FLP) in trees. Let \(T = (V, E, c, d, \ell , \mu )\) be an undirected rooted tree, where each node \(v \in V\) has a weight \(d(v) \ge 0\) denoting the demand amount of v as well as a weight \(\ell (v) \ge 0\) denoting the cost of opening a facility at v, and each edge \(e \in E\) has a weight \(c(e) \ge 0\) denoting the cost on e and is associated with a function \(\mu (e,t) \ge 0\) denoting the cost of opening a facility at a point x(e, t) on e where t is a continuous variable on e. Given a subset \(\mathcal {D} \subseteq V\) of clients, and a subset \(\mathcal {F} \subseteq \mathcal {P}(T)\) of continuum points admitting facilities where \(\mathcal {P}(T)\) is the set of all the points on edges of T, when two facilities are installed at a pair of continuum points \(x_1\) and \(x_2\) in \(\mathcal {F}\), the total cost involved in CC2FLP includes three parts: the cost of opening two facilities at \(x_1\) and \(x_2\), K times the cost of connecting \(x_1\) and \(x_2\), and the cost of all the clients in \(\mathcal {D}\) connecting to some facility. The objective is to open two facilities at a pair of continuum points in \(\mathcal {F}\) to minimize the total cost, for a given input parameter \(K \ge 1\). This paper focuses on the case of \(\mathcal {D} = V\) and \(\mathcal {F} = \mathcal {P}(T)\). We first study the discrete version of CC2FLP, named the discrete connected 2-facility location problem (DC2FLP), where two facilities are restricted to the nodes of T, and devise a quadratic time edge-splitting algorithm for DC2FLP. Furthermore, we prove that CC2FLP is almost equivalent to DC2FLP in trees, and develop a quadratic time exact algorithm based on the edge-splitting algorithm. Finally, we adapt our algorithms to the general case of \(\mathcal {D} \subseteq V\) and \(\mathcal {F} \subseteq \mathcal {P}(T)\).     

Family Characteristics and Mate Selection: Evidence From Computer‐Assisted Dating in Japan

Research on mate selection rarely considers singles' preferences for their future partners' family configurations and experiences. Using online dating records from a matchmaking agency in Japan, a society with a strong emphasis on family and kinship, we examine how singles' responses to date requests correspond to potential mates' family circumstances. Results showed that singles' preferences for potential partners' family characteristics stem from a concern about future obligations toward the partner's family and stereotypes associated with certain family traits. Singles are less likely to accept requests from those from large families, which are seen as traditional. Being from a large family, however, hampers individuals' dating chances more if they are firstborn and have no brothers, two conditions that make them the designated child to care for elderly parents. We also find that Japanese singles seek partners with more of the universally valued family traits rather than traits similar to their own.     

《哈姆雷特》中"约之链"的审美特质

《哈姆雷特》蕴含的契约意识具有独特的审美特质。哈姆雷特通过一系列约定，和周围的人一起让混沌的世界恢复了秩序。这一切，不是靠武力和冲动，而是以自由意志为基础的缔约能力。契约的破与立的是故事情节发展的内动力，契约的守与背是哈姆雷特复仇的原动力，契约的自由意志与道德责任是莎士比亚对人性和社会的哲学思考。从这个角度来说，哈姆雷特试图遵循“奥卡姆剃刀”原则，依据约定的破与立，将国家恢复到有序状态。     

民族声乐作品中时代性的把握 ——以《我的祖国》为例

民族声乐作品的时代性,即作品与时代两者之间的关系,主要表现在社会生活、个人因素和演唱方法三个方面.特别是面对如《我的祖国》这类经典时代作品时,把握作品中的时代性相关因素,是理解其时代性风格特点的根本之所在.     

“一带一路”相关文件政策强度与省域经济开放度关系研究——“一带一路”沿线18个省份实证分析

文章的特色和理论意义在于,尝试量化"一带一路"沿线18个省份"一带一路"相关政策文件,以设计政策效力、政策措施与政策保障的评判要点为基础,确定政策措施强度和政策保障强度.细致讨论"一带一路"文件的政策强度与经济开放度提升之间的关系,并讨论该关系在东西部地区的差异以及政策保障强度在政策措施强度与经济开放度关系之中的调节效应.研究发现:政策措施强度能够正向促进省域经济开放度的提升;在经济开放度高于10％的省份中,政策保障强度正向调节政策措施强度与经济开放度提升之间的关系,政策措施强度和政策保障强度之间存在互补关系;政策措施强度中资金融通强度对于沿线省域经济开放度的提升有着最显著的正向影响,政策沟通强度对于沿线省域经济开放度的提升影响不显著;政策措施强度对省域经济开放度的提升存在地区差别,西部地区更注重"一带一路"倡议所带来的机会.建议:"一带一路"沿线省份在政策设计上,不仅要对政策沟通、设施联通、贸易畅通、资金融通和民心相通等内容作出合理规划和布局,还应对保障机制作出可操作性的安排.     

非法集资投资人地位及投资合同效力的反思与破解

当前，我国法律框架对非法集资案件中投资人诉讼地位及投资合同效力还缺乏明确的法律规定，使得不同案件的裁判尺度难以统一，再加上此类案件普遍存在刑民交叉的特点，处置程序缺乏相应规范成为司法实践中面临的严峻问题。针对投资人诉讼地位，可结合法益保护、刑事被害人的正当性及有利司法实践原则，将集资诈骗罪中的投资人界定为被害人，非法吸收公众存款罪中的投资人界定为证人。针对投资合同效力，可结合民法典及刑事立法精神，将集资诈骗罪中的投资合同认定为无效合同；非法吸收公众存款罪中则应结合当事人的主观意图等对投资合同的有效性、是否可撤销等进行具体区分。同时建议设立公告程序及诉讼代表人制度，充分保障非法集资案件中投资人及第三人参与诉讼的合法权益。
