Distribution-free tests of stochastic dominance for small samples

One variable is said to “stochastically dominate” another if the probability of observations smaller than x is greater for one variable than the other, for all x. Inferring stochastic dominance from data samples is important for many applications of econometrics and experimental psychology, but little is known about the performance of existing inferential methods. Through simulation, we show that three of the most widely used inferential methods are inadequate for use in small samples of the size commonly encountered in many applications (up to 400 observations from each distribution). We develop two new inferential methods that perform very well in a limited, but practically important, case where the two variables are guaranteed not to be equal in distribution. We also show that extensions of these new methods, and an improved version of an existing method, perform quite well in the original, unlimited case.     

Applying memories of reinforcement outcomes mainly to Pavlovian conditioning

A theory devised initially on the basis of instrumental reward schedule data, such as the PREE, was extended to deal with various Pavlovian findings. These Pavlovian findings include blocking, unblocking, relative validity, positive and negative patterning, renewal, reinstatement, reacquisition, and inhibition. In addition, the sequential model was discussed in relation to the rule-learning view of Hulse and Dorsky (1977) employing data from a report by Bloom and Capaldi (1961).     

Song recognition in zebra finches: Are there sensitive periods for song memorization?

Male zebra finches learn to sing songs that they hear between 25 and 65 days of age, the sensitive period for song learning. In this experiment, male and female zebra finches were exposed to zebra finch songs either before (n = 9) or during (n = 4) the sensitive period. Following song exposure, recognition memory for the songs was assessed with an operant discrimination between familiar and novel songs. Zebra finches that were exposed to songs between 22 and 30 days of age discriminated between familiar and novel songs; zebra finches exposed to songs from 9 to 17 days of age did not. Failure to memorize songs heard prior to the sensitive period may contribute to the exclusion of those songs from the repertoire of songbirds.     

A Recess Evaluation with the Players: Taking Steps Toward Participatory Action Research

This qualitative study, part of a Canadian national study of fathers’ involvement, opened up First Nations and Métis fathering as a new area of inquiry. Conversational interviews with 80 Indigenous fathers illuminated the socio-historical conditions that have shaped Indigenous men’s experiences of learning to be a father and becoming a man in the context of changing gender relationships and the regeneration of circles of care. Indigenous fathers’ experiences unfold in a socio-historical context fraught with difficulties. However, the study findings suggest cultural strengths and sources of resilience unseen in research and community programs driven by Euro-western perspectives. This research can inform efforts to reduce systemic barriers and reconstitute positive father involvement following disrupted intergenerational transmission of fathering in Canada and elsewhere.     

Covariation of self‐ and other‐directed aggression among inpatient youth: continuity in the transition to treatment and shared risk factors

Although other‐ and self‐directed aggression covary in very high‐risk youth, these forms of aggression infrequently are studied simultaneously. Understanding better their covariation is an important task for improving services to high‐risk youth. In this study, data from the clinical records of 476 youth admitted to secure inpatient treatment were analyzed to examine relations among self‐ and other‐directed aggression exhibit before and during inpatient treatment. Analyses tested the hypotheses that self‐ and other‐directed aggression would tend to covary and display continuity from pre‐treatment to in‐treatment. Also tested were the hypotheses that youth with histories of co‐occurring self‐ and other‐directed aggression would show the highest levels of aggression during treatment and the greatest degree of personal and contextual risk on entering treatment. These hypotheses were largely supported. Exploratory analyses revealed interesting discontinuities in aggression (aggression emitted only before or during treatment) with critical implications for research and practice with youth receiving clinical care, especially those in institutional placements.

Kierkegaard on the (un)happiness of faith

Hegel famously accuses Christianity of ‘unhappy consciousness’: it has a normative goal – union with the divine – that it cannot, in principle, satisfy. Kierkegaard was intimately aware of this criticism and, unlike some of Hegel’s other accusations, takes it seriously. In this paper my co-author and I investigate the way in which Kierkegaard addresses this issue in two texts published in 1843: Fear and Trembling and ‘The Expectancy of Faith’. We are especially interested in how the two texts describe faith’s relationship to finitude: for instance, whether the person of faith is permitted to expect that God will bless her in particular and concrete ways. My co-author and I offer competing interpretations. I argue that there is a deep tension in the way faith is described in the two texts; my co-author argues that there is consonance.     

论孙中山民主主义的服务道德

孙中山在其三民主义的政治基础上,形成了他的民主主义的伦理思想,突出特色是他所倡导的“服务道德”。其要点是,以民主平等取代等级特权制度,这是服务道德的政治前提;实行人道主义、维护人的尊严,这是服务道德的基本要求;铲除皇帝思想、树立公仆观念,这是实践服务道德的基本途径。孙中山的伦理思想有明显的历史局限性,但是,他的“服务道德”思想仍然是值得借鉴的。     

On Luo Congyan’s Ethics

Luo Congyan put forward the idea that benevolence is the substance while righteousness is its function, which placed the intrinsic value of human beings on a more fundamental position and affirmed the unity of benevolent principle and universal norms from the perspective of the relationship between substance and function. The unity of benevolence and righteousness involves the connection between value and norms, and the latter relate to the relationship between morality and law in the broader sense. On the basis of the idea of using both benevolence and righteousness, Luo Congyan examined the relationship between morality and law. Corresponding to the emphasis on the role of both law and political power, Luo Congyan concerned himself with how to establish rational interpersonal relationships in various ways. Furthermore, Luo Congyan emphasized the significance of behavior in everyday life, while he affirmed that the universal principle should be followed. In this way, he developed the earlier Confucian thought. Translated from Studies in Ethics by Xiao Mo     

Flowing Within the Text: A Discussion on He Lin’s Explanation of Zhu Xi’s Method of Intuition

The author examines He Lin’s interpretation of Zhu Xi’s method of intuition from a phenomenological-hermeneutical perspective and by exposing Zhu’s philosophical presuppositions. In contrast with Lu Xiangshan’s intuitive method, Zhu Xi’s method of reading classics advocates “emptying your heart and flowing with the text” and, in this spirit, explains the celebrated “exhaustive investigation on the principles of things (ge wu qiong li).” “Text,” according to Zhu, is therefore not an object in ordinary sense but a “contextual region” or “sensible pattern” that, when merged with the reader, generates meanings. Furthermore, by discussing the related doctrines of Lao Zi, Zhuang Zi, Hua-Yan Buddhism, Zhou Dunyi, and Zhu Xi’s own “One principle with many manifestations (li yi fen shu),” the author identifies the philosophical preconditions of Zhu’s method. Based on this analysis, the author goes on to illustrate Zhu’s understanding of “observing potential yet unapparent pleasure, anger, sorrow and happiness” and “maintaining a serious attitude (zhu jing).”     

A contemporary interpretation of Marx’s thoughts on modernity

Unlike some western scholars who limit their interpretation of modernity and its source to conceptual, cultural, value, and psychological dimensions, Marx pointed out that modernity came mainly from modern production system. Starting from the historical context of his time, Marx explored various aspects of modernity and pointed out that modernity was inherent in the logic of capital, resided in the process of historical evolution, arose in social conflicts and segmentation, and presented itself in a global horizon. The logic of capital, the historical viewpoint, the theory of contradiction and a global perspective are fundamental in Marx’s analysis of the problems of modernity. Marx’s ideas of modernity are methodologically significant to the construction of modernity in contemporary Chinese society. __________ Translated from Zhongguo Shehui Kexue 中国社会科学 (China Social Sciences), 2005 (4) by Xing Lijun
