基于IAT的内隐物品-性别刻板印象研究
The Research of Implicit Object-Gender Stereotype Based on IAT
 [PDF]

Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.64071
Abstract:
内隐联想测验(Implicit Association Test,简称IAT)是一种研究内隐社会认知的新方法。本实验采用IAT实验设计,目的在于考察大学生的内隐物品-性别刻板印象。结果发现,IAT方法能检测到大学生存在“棱角分明的物品与男性联系,有曲线的物品与女性联系”的内隐物品-性别刻板印象;IAT所测量到的内隐物品-性别刻板印象有性别差异。
Implicit Association Test (IAT) is a new research method of the implicit social cognition. The implicit association test is used to measure implicit object-gender stereotype of university students in this study. The result indicates that, among university students, there is an implicit object- gender stereotype, which means angular objects belong to male and curvy objects belong to female; no gender difference is found in implicit object-gender stereotype by IAT.
两种幸福悖论:收入悖论和欲望悖论
,
华东师范大学学报(哲学社会科学版) , 2013,
Abstract: 有一种幸福公式是幸福=收入/欲望。为了“幸福最大化”,可以选择两种完全相反的路径,一种是尽量做大公式中的分子(增加收入),另一种是尽量做小公式中的分母(减少欲望)。前一种路径导致的幸福悖论是“收入悖论”(伊斯特林悖论,以现代西方为代表),后一种路径导致的幸福悖论则是“欲望悖论”(以古代中国为代表)。两个不同的幸福悖论其实是在一个统一的经济学框架之内,这也正是两个悖论的破解方法。

Due to its advantages in improving our knowledge about the P fractions in environmental samples, the 31-P nuclear magnetic resonance (31P-NMR) technology has received extensive attention. This paper summarized the current studies on the characterization of P fractions in sediments by using this technology, and described the technical principles, sample preparation method and analytical procedures of this technol- ogy. The preparation procedures of environmental samples have a significant influence on the accuracy and precision of testing results, including determination of sample pretreatment, extraction time, sample to ex- traction ratio and concentration method. The specific application fields of this technology were also summa- rized in this paper. 31P-NMR technology has been applied in the field of Soil, Lake, Ocean, Wetland, and has made a number of achievements. Some future research focuses were expected in this paper in order to pro- vide theoretic support for the development and application as well as standardization of 31P-NMR technology in the future.

Abstract: 大型火力发电厂的实时控制过程中,许多数据之间呈现复杂的非线性关系,而数据挖掘技术能从数据中发现知识或规则,及时分析、调整参数。该文利用数据挖掘方法确定监控参数的基准值,为火电机组耗差分析提供重要依据。介绍了数据挖掘方法的相关理论,研究并应用聚类算法确定热力设备监控参数的基准值模型。采用k-means法分析实时运行数据,分别挖掘再热器压损和锅炉排烟温度的基准值,所得锅炉运行主要监控参数的基准值模型经样本图证实效果良好。为基准值模型的确定提供了一个新的思路和有效方法。
地黄绒毡层二型性的超微结构研究
,,鲁国庆,周固
植物科学学报 , 1994,
Abstract: ?地黄Rehmanniaglutinosa(Gaertn.)Libosch的花药绒毡层具二型性,来源于初生壁细胞的p-绒毡层,细胞较小,为分泌型绒毡层,在小孢子阶段产生乌氏体,于两细胞花粉阶段解体。来源于药隔的c-绒毡层细胞较大,解体的时间早于p-绒毡层,不同药室的c-绒毡层解体的起始时间不一致,可始于小孢子母细胞减数分裂、四分体或小孢子阶段;其径向壁与面向药室的壁也较早地开始解体,细胞质碎片与细胞器流入药室,分散在小孢子之间。较早解体的c-绒毡层细胞不产生原乌氏体与乌氏体,部分解体较晚的c-绒毡层细胞能产生原乌氏体,但极少形成乌氏体。
β-环糊精-烟酸超分子体系的合成、表征及结构
周卫,,缪文明
化学学报 , 2001,
Abstract: 合成了β-环糊精-烟酸超分子体系,用差热分析和核磁共振等方法进行了表征,利用X射线衍射数据确定了其结构。分子式为(C42H70O35)·(C6O2H5N)·7.53(H2O)·0.73(CH3OH),属单斜晶系P21空间群,a=1.51616(4),b=1.02642(4),c=2.09296(3)nm,β=110.209(2)°,V=3.05659(3)nm^3。最小二乘修正结果,R=0.0576。晶体结构测定结果表明,这个超分子体系是属于较少见的“浅包结”方式,客体位于环糊精主体窄口端,伯羟基的O(66),O(67)原子及大多数水分子处于无序状态,大量存在的分子内和分子间氢键,形成了一个密集的氢键网络。氢键是超分子体系形成及稳定存在的主要驱动力。

 [PDF]

Abstract:

利用自行车在短途交通方面的优势,将公共自行车纳入公共交通体系,作为城市公共交通(轨道交通、公交)的延续,形成“公共自行车 + 公共交通 + 公共自行车”的出行模式,解决居民公交出行(尤其是轨道交通出行)接驳问题,加大城市公共交通吸引力,扩大公共交通服务范围,倡导绿色出行方式。公共自行车租赁系统极大地方便了人们的出行,解决了市民出行的“最后一公里”问题。但是,在自行车租赁系统运行初期,由于经验的缺乏,在租赁点的设置和自行车的调度以及整个系统的进一步完善还需作出不断的努力。根据问卷数据可知,北京市公共自行车服务总体满意度为58%,可见市民对公共自行车服务满意度一般,系统服务质量仍需进一步提高。通过对满意度调查结果的因子分析,可知我们需着重改善的是:重要但绩效表现欠佳的要素,即车况质量、租车可得性、服务网点布局与数量。
Taking the advantage of bicycles in short-distance transport and putting public bicycles into public traffic system will become an important city public means of transport, which will form a travel mode as “public bicycle + public transport + public bicycle”. It can solve the problem of residents’ transit connection, increase the urban public attraction and enlarge the scope of public transport service. All of the above will lead to a greener way of travel. Public bicycle system is convenient for people’s travel, which solves the problem of residents’ “the last kilometer”. However, at the beginning of the system’s running, due to the lack of experience, we need to further strengthen the settlement of bicycles and make more efforts to the perfection of the whole system. According to the questionnaire survey, the satisfaction rate of the public bicycle service in Beijing was only 58% by then. The residents’ satisfaction of the public system is still on a low level. Therefore the public bicycle system still need further improving in service. Through factor analysis of the satisfaction, we know that the quality of the bicycles, the availability of bicycles and the settlement of service spots are the top three important factors of satisfaction that need to be improved; enhancing them will make an obvious improvement to the public bicycle system.
