均等分区问题模型、算法及应用

孔云峰
Subjects: Geosciences >> Geography

分区问题广泛应用于地理、经济、政治、商业、公共服务等领域。均等分区问题是其中一类问题,通常要求分区人口数量或任务量均等、几何形状紧凑和空间连续,应用于选区、销售区和巡逻区的划分。本文针对均等分区问题提出了一个混合整型线性规划模型,并设计了一个基于迭代局部搜索(ILS)的混合算法。该算法从三个方面扩展ILS:群解搜索、VND搜索及SPP模型改进。选择5个区域对模型和算法进行测试,结果表明:数学模型能够求解空间单元数量为324的案例;混合算法优化性能优异,鲁棒性强,计算效率较高。所提出的均等分区问题适用于政治分区等经典问题,在新冠疫情应急服务等领域也具有应用潜力。

跨期决策中的负折扣现象及其机制

Subjects: Psychology >> Social Psychology
Subjects: Psychology >> Applied Psychology

主流跨期决策模型认为,跨期决策存在一个时间折扣过程。时间折扣是指人们会根据将来获益或损失的延迟时间对其效用进行折扣,折扣后的效用小于原来的效用,而负折扣现象违背了时间折扣过程。负折扣现象出现在金钱、非金钱的获益与损失领域,其可能的解释机制为预期情绪。目前关于负折扣现象的研究,较少验证其影响机制,未来的研究可以结合眼动追踪和fMRI技术探讨其机制,并丰富对负折扣现象的影响因素研究。

精神分析的主体间转向:理论特征与分歧

张巍; 郭本禹; 张磊
Subjects: Psychology >> History of Psychology

主体间理论是当代精神分析领域最重要的取向之一。与更传统的精神分析相比,其理论特征表现为从区分“内/外”空间到强调“之间”的空间、从“主体—客体”关系到“主体—主体”关系、从顿悟到行动、从基础主义和实证主义到诠释学和建构主义。尽管存在术语的混乱和观点的分歧,但精神分析的主体间转向几乎遍及各个流派,广泛影响了北美洲、欧洲和拉丁美洲的诸多分析师。未来的主体间理论需要保持开放的态度,持续与先前的理论、临床资料和其他学科领域对话。

定向遗忘的编码加工机制

寇东晓; 顾文涛
Subjects: Psychology >> Cognitive Psychology

有目的的遗忘(定向遗忘)需要耗费认知努力吗?有研究发现,定向遗忘可能是被动衰减的结果,即F项目(需要遗忘的项目)未获得有效复述是选择性复述了R项目(需要记住的项目)造成的,这一加工过程不需要认知努力;但也有研究表明,定向遗忘过程可能是遗忘线索诱发的对记忆加工的主动抑制,需要耗费认知努力,脑认知研究中发现的前额叶ERPs成分为这一机制提供了证据。还有一种观点认为,定向遗忘编码过程可能同时包含主动抑制与被动衰减,但是尚不清楚两种加工机制相互作用的方式。为进一步澄清定向遗忘编码阶段的认知机制,未来研究需要将非认知因素纳入考察,并关注不同人群的定向遗忘特征,在此基础上尝试解决理论争议。

三维晶体中的演生粒子百科

Subjects: Physics >> Condensed Matter: Electronic Structure, Electrical, Magnetic, and Optical Properties

The past decade has witnessed a surge of interest in exploring emergent particles in condensed matter systems. Novel particles, emerged as excitations around exotic band degeneracy points, continue to be reported in real materials and artificially engineered systems, but so far, we do not have a complete picture on all possible types of particles that can be achieved. Here, via systematic symmetry analysis and modeling, we accomplish a complete list of all possible particles in time reversal-invariant systems. This includes both spinful particles such as electron quasiparticles in solids, and spinless particles such as phonons or even excitations in electric-circuit and mechanical networks. We establish detailed correspondence between the particle, the symmetry condition, the effective model, and the topological character. This obtained encyclopedia concludes the search for novel emergent particles and provides concrete guidance to achieve them in physical systems.

COVID-19 中稀缺对恐慌消费的影响:链式中介模型分析

马欣然; 廖江群
Subjects: Psychology >> Social Psychology

[目的] 研究旨在考察突发公共危机中稀缺对恐慌消费的影响及其心理路径和边界条件。 [方法] 研究一借助大数据使用客观产品反映稀缺的影响。研究二在疫情爆发期进行了高生态效度的全国性线上问卷调查。研究三在不同的突发公共危机情境中启动稀缺验证因果。 [结果] 稀缺可以正向预测和加剧恐慌消费(研究1-3),控制感和恐慌情绪在其中起链式中介作用(研究2-3),但这一模式更适用于高风险的突发公共危机事件(研究3a\3b\3c)。 [局限]控制感与恐慌情绪的链式中介效应不能解释低风险感知的突发公共危机中稀缺引起恐慌消费的心理路径,未来研究需继续探究。更为客观的稀缺和恐慌消费指标值得进一步发掘和考察。 [结论] 高风险性的突发公共危机中,稀缺会降低控制感,增加恐慌情绪,最终引起恐慌消费。

Psychopathy and Moral Decision Making: A Data Reanalysis Exploration

Chuanjun Liu; Jiangqun Liao
Subjects: Psychology >> Social Psychology

Previous research found that people with higher level of psychopathy trait would endorse more to the harmful but beneficial action in traditional moral dilemmas. Three possibilities for this effect were confounded: People with higher psychopathy trait, 1) care more about the beneficial consequences; 2) care less about the “no harm” norms; 3) just prefer action irrespective of consequences and norms. A multinomial processing tree model named “CNI” was developed and claimed to dissociated these three possibilities. Four studies have applied CNI model to study the psychopathy-moral decision relationship. However, the CNI model presupposes the agent sequentially processes consequences-norms-generalized inaction/action preferences, which makes the estimated parameters biased and untenable. More recently, an alternative algorithm named “CAN” was developed based on the same data structure to overcome the limitations of CNI model. We applied CAN algorithm and reanalyzed the raw data of the four studies on psychopathy-moral decision relationship. The results demonstrated that people with higher psychopathy trait have weaker consequences and norms sensitivities, stronger overall action preferences, stronger inaction/action preferences irrespective of norms and consequences, and weaker moral principles obedience. Furthermore, the mediation and moderation reanalysis explorations demonstrated that instrumental harm and moral identity partly mediate the psychopathy-moral decision relationship and that perceived societal standards rather than personal standards when making moral decisions can alleviate the positive effects of psychopathy on overall action preference and action preference irrespective of norms and consequences. Present reanalysis exploration study clarified and deepened our insights on the relationship between psychopathy and moral decisions. Theoretical and methodological implications were also discussed.

姓名对个体心理与行为的实际影响:证据和理论

包寒吴霜; 蔡华俭
Subjects: Psychology >> Social Psychology

姓名不仅会影响他人的印象与评价,还可能会影响个体实际的心理与行为。近几十年来,心理学家在决策、成就、健康、人格四个领域开展了大量实证研究来考察姓氏或名字对个体的实际影响。姓名的多个维度(如独特性、性别倾向、含义效价、温暖–能力维度等)在不同程度上可以预测这些领域的心理与行为(包括职业决策/生活决策/经济决策、职业成就/学业成就、生理健康/心理健康/犯罪行为、人格特质/心理需要/面孔特征等)。但是,现有研究证据比较混杂,理论解释有待完善。未来研究应全面考虑姓名维度,重点解决可重复性、因果关系、心理机制、跨文化普遍性等问题,努力构建更系统、更包容的理论来解释姓名的心理与行为效应。

多孔介质间突变界面在油气藏开发中广泛存在。传统的渗流理论认为压力和达西速度在非连续界面处是连续的,我们在以往的研究对其进行了证伪。多孔介质物性突变界面为固定界面,本文在前期不可压缩流体的基础上,以气-水两相为例,考虑流体的压缩性,建立了这类突变界面处流体压力和渗流速度的连接条件。研究结果表明,在多孔介质固定的物性突变界面:(1)总体压力必然连续,但各相流体压力可以不连续;(2)总渗流速度相等,但各相流体的渗流速度可以不连续;(3)固定突变界面与移动突变界面的连接条件不同,不能用Rankine–Hugoniot条件描述;(4)根据突变界面的连接条件以及两相达西公式根据界面两端压力以及流体分布可计算出跨物性突变界面的各相流体的流速,跨物性的突变界面的流量应取上游值
