复杂视觉图形辨认的实验研究

实验材料是取样规则不同的两组(有限制组和无限制组)矩阵图形和离散度不同的两组(大离散度组和小离散度组)矩阵图形。每个图形以两种速度及在三个距离上呈现。被试者的任务是从比较图形中再认出先前呈现的那个图形。结果表明:被试者再认无限制组图形的成绩优于有限制组的成绩,小离散度组的成绩也优于大离散度组的成绩。速度因素对辨认的影响大于距离因素的影响。由取样规则所带来的关系参数和离散度这个物理的参数可用于预测图形辨认的成绩。     

在包含多种提取内容时加工层次对自由回忆和再认的影响

本实验的目的是探索加工层次(方式)对自由回忆和再认的影响,实验条件同时包含适合于原来加工方式的提取内容以及不适合于原来加工方式的提取内容。结果表明,深层的意义水平的加工方式产生了最好的保持。从提取内容与加工方式的一致性对结果进行了讨论,最后强调了加工方式对提取是极端重要的。     

马克思主义和人本心理学

美国人本主义心理学,就其关于人的价值的观点而论,可以说主要是从心理学角度对人的本质及其实现问题的研究。这当然并不是一个新问题。早在一个多世纪以前,马克思就曾从哲学、心理学和经济学角度对此进行过系统的探讨。     

Friendship patterns of overseas students: A functional model1

The respondents were 30 foreign students at the University of Hawaii (6 each from Japan, Korea, the Philippines, Taiwan, and Thailand), and 6 host national (American) students, balanced for sex. The subjects identified their 5 best friends, and the 5 people with whom they spend most of their time. The subjects were then presented with a list of 15 activities, and identified a preferred companion for each of the situations. The data were used to test a functional model of the academic sojourn, which predicts that foreign students will belong to three social networks, in descending order of salience: a) a conational network whose function is to affirm and express the culture of origin; b) a network with host nationals, whose function is the instrumental facilitation of academic and professional aspirations; and c) a multinational network whose main function is recreational. The results confirmed the existence, predicted differential function, and salience hierarchy of these three social networks, and reconciled previous conflicting reports regarding the social relations of foreign students.     

The sex by race interaction in cognitive measures

Data consisting of 79 cognitive measures from Project TALENT for 100,000 white and black high school students have been analyzed for possible race by sex interactions. Control variables included geographical area, grade in high school, and socio-economic class. Race by sex interactions are largest when socioeconomic class is controlled and are highly related to the size of the main effect of sex as well. White boys and girls differ more than black boys and girls whether the overall sex difference favors males or females. Sex by grade and, to a lesser extent, sex by area interactions were also moderately large and consistent with the size of the main effect of sex. Since there are no consistent relationships with other main effects, and since the measures producing sex differences also tend to produce the interactions, it is concluded that sex differences and the interactions with sex share the same causes. Differences between these results and those of Jensen are also discussed.     

全球地域化:基督宗教在华传播史的一种诠释——对章开沅"传播与植根"观念的解读

章开沅自20世纪80年代中期涉足中国基督宗教史研究领域.他通过深入考察基督宗教在中国传播的历史进程,精辟阐释中西文化的巨大差异,透彻解析中外基督徒有识之士的经典著述,站在跨文化对话的高度,对中国基督宗教史予以"全球地域化"解读.章开沅认为,只有构筑中国本土化的世界观与价值观,才是基督宗教在华"传播与植根"的必由之路.     

Strategic Revenue Management under Uncertainty: A Case Study on Real Estate Projects in India

This paper proposes an approach for strategic revenue management under uncertainty for real estate projects. It integrates three modelling techniques: first, artificial neural network integrated support vector machines for forecasting the profit and loss‐making real estate residential projects; second, analytical network process approach using decision making trials and evaluation laboratory methodology for establishing interrelationships among factors; and third, multiobjective genetic algorithm approach for obtaining optimal numbers and types of apartments in a real estate project. We compare the respective revenues generated with the new number of apartments and price from the suggested revenue maximization model and that of the old practiced one through a case study of India.

Stopping rules for multi-category computerized classification testing

Computerized classification testing (CCT) aims to classify persons into one of two or more possible categories to make decisions such as mastery/non-mastery or meet most/meet all/exceed. A defining feature of CCT is its stopping criterion: the test terminates when there is enough confidence to make a decision. There is abundant research on CCT with a single cut-off, and two common stopping criteria are the sequential probability ratio test (SPRT) statistic and the generalized likelihood ratio statistic (GLR). However, there is a relative scarcity of research extending the SPRT to the multi-hypothesis case for when there is more than one cut-off. In this paper, we propose a new multi-category GLR (mGLR) statistic as well as a stochastically curtailed version of the CCT with three or more categories. A simulation study was conducted to show that the mGLR statistic outperformed the existing stopping rules by generating shorter average test length without sacrificing classification accuracy. Results also revealed that the stochastically curtailed mGLR successfully increased test efficiency in certain testing conditions.     

Losing My Religion as a Natural Experiment: How State Pressure and Taxes Led to Church Disaffiliations between 1940 and 2010 in Germany

The sociological literature has produced a remarkably consistent picture of the quantitative patterns of religious disaffiliations in Western countries. This article argues, and demonstrates, that strong changes in a social context may lead individuals to disaffiliate rapidly, leading to very different aggregate effects from those in the “western model.” We use the unique situation of the separation of Germany from 1949 to 1989 and its subsequent reunification as a “natural experiment” to show just how much the relationships routinely found can be disrupted under changed conditions. The state socialist “treatment” affected religious disaffiliations in East Germany profoundly as it (a) made disaffiliations 10 times more probable in the East than in the West in the 1950s and 1960s, (b) shielded East German church members from factors that led to mass disaffiliations in the West in the late 1960s and early 1970s, (c) reversed the education‐disaffiliation link in the East, thus making disaffiliation more likely among the less educated, and (d) led to an especially strong increase in disaffiliations in the East right after the reunification
