Zhuangzi the Poet: Re-Reading the Peng Bird Image

The image of the Peng bird, which opens the Zhuangzi text, is not the product of metaphysical reasoning. An inspiring example of soaring up and going beyond, the image is used to broaden the outlook of the small mind; its function is thus more therapeutic than instructional. With its rich poetic and experiential content, the image of the Peng refuses to be reduced to an abstract concept, or a mere signifier of certain philosophical position. Misreading of the image results from any attempt to accurately “size up” its philosophical implication by measuring it quantitatively against a spectrum of positions and values. To see only the superficial “inconsistencies” in Zhuangzi’s argument and to read the wind under the Peng’s wings as a handicap that it needs to overcome in order to embark on its “free and easy wandering” is, in the name of logic and “consistency,” to ignore the big picture Zhuangzi presents.     

Normische Gesetzeshypothesen und die wissenschaftsphilosophische Bedeutung des nichtmonotonen Schliessens

Normic Laws and the Significance of Nonmonotonic Reasoning for Philosophy of Science. Normic laws have the form ‘if A then normally B’. They have been discovered in the explanation debate, but were considered as empirically vacuous (§1). I argue that the prototypical (or ideal) normality of normic laws implies statistical normality (§2), whence normic laws have empirical content. In §3–4 I explain why reasoning from normic laws is nonmonotonic, and why the understanding of the individual case is so important here. After sketching some foundations of nonmonotonic reasoning as developed by AI-researchers (§5), Iargue that normic laws are also the best way to understand ceteris paribus laws (§6). §7 deals with the difference between physical and non-physical disciplines and §9 with the difference between normicity and approximation. In §8 it is shown how nonmonotonic reasoning provides a new understanding of the protection of theories against falsification by auxiliary hypotheses. §10, finally, gives a system- and evolution-theoretical explanation of the deeper reason for the omnipresence of normic laws in practice and science, and forthe connection between ideal and statistical normality.

Tableau algorithms for factor analysis by instrumental variable methods

Simple tableau algorithms are given for the noniterative instrumental variable (FABIN 2) and two stage regression (FABIN 3) factor loading estimates of Hägglund. Corresponding generalized least squares estimates of factor covariances and unique variances are introduced. An example is given for the purpose of illustration and comparison.This research was supported by NSF Grant MCS-8301587.     

A behavioral analysis of incentive prompts for motivating seat belt use

The seat belt usage of drivers was observed at the entrance to two campus parking lots during morning arrival times. After 11 days of baseline, fliers which prompted seat belt wearing were handed to drivers of incoming vehicles. At one parking lot all fliers offered a chance to win a prize (noncontingent rewards); while at the second lot only those fliers given to seat belt wearers included a chance to win a prize (contingent rewards). After 24 consecutive observation days, these interventions were removed for 14 days of withdrawal. The recording of vehicle license plates enabled an analysis of belt usage per individual over repeated exposures to the experimental conditions. At the lot with the contingent reward intervention, mean belt usage was 26.3% during baseline, 45.7% during treatment, and 37.9% during withdrawal. At the noncontingent reward lot, the mean percentage of belt wearing was 22.2% during baseline, 24.1% during treatment, and 21.8% during withdrawal. The analysis of repeated exposures per individual verified that only contingent rewards influenced substantial increases in belt wearing, and showed that most of the influence occurred after the initial incentive prompt.     

Extreme elemental processing in a high schizotypy population: Relation to cognitive deficits

The cognitive deficits observed in schizophrenia have been characterized as a failure to utilize task-setting information to guide behaviour, especially in situations in which there is response conflict. Recently, we have provided support for this account; high schizotypy individuals demonstrated inferior biconditional discrimination performance compared to low scorers, but were not impaired on a simple discrimination that did not require the use of task-setting cues. These results may, however, also be explained by the way in which individuals with high schizotypy process stimulus compounds. Here, we examine the initial approaches to solving biconditional and control discrimination tasks of participants with high and low schizotypy scores. In particular, we focus on performance during the first block of training trials to capture processing style before the acquisition of the discrimination tasks. Participants scoring highly on the introvertive anhedonia subscale (which has been allied to the negative and cognitive symptoms of schizophrenia) demonstrated better biconditional performance during the first block of training trials than did low-schizotypy individuals, consistent with a highly elemental approach to stimulus processing. Subsequent recognition tests confirmed this analysis demonstrating that the pattern of performance observed in participants with high schizotypy was associated with a failure to discriminate conjunctions of items that had been seen before from those that had not. These results suggest that the negative/cognitive symptoms of schizophrenia may reflect an extreme bias towards elemental, as opposed to configural, processing of stimulus conjunctions.     

Mortality and World Hunger

Why does world hunger hold an inferior place on the contemporary moral agenda? Proposed answer: because it is a political, not a moral problem. It is not a moral problem, because morality needs two conditions fulfilled: that those be in some way close to the agent unto whom that agent is doing something that is to be morally assessed; and that the relevant good or bad states or events can be clearly credited to some particular agent or agents. Neither condition is fulfilled in the case of world hunger. This explains morality's failure to come to grips with it. Yet, while lacking morality's endorsement, the abolition of world hunger may still be a political goal.     

Informal versus formal mathematics

We discuss Kunen’s algorithmic implementation of a proof for the Paris–Harrington theorem, and the author’s and da Costa’s proposed “exotic” formulation for the P = NP hypothesis. Out of those two examples we ponder the relation between mathematics within an axiomatic framework, and intuitive or informal mathematics.

理性-经验加工对不公正情绪和行为反应的影响:公正敏感性的调节作用

基于认知-经验理论,采用行为实验法和情境故事法,探讨了不同信息加工方式对不公正情绪和行为反应的影响,以及受害者敏感性对两者关系的调节作用。结果表明,与理性加工相比,经验加工下个体对不公正有更强烈的负性情绪反应,合作意向更低;受害者敏感性调节加工方式与不公正行为反应之间的关系,即受害者敏感性低时,加工方式与人际公正对合作意向交互作用显著,受害者敏感性高时,加工方式与人际公正对合作意向没有交互作用。     

The Effect of Children's Sleeping Arrangements (Communal vs. Familial) on Fatherhood Among Men in an Israeli Kibbutz

Abstract

The author examined the effect of children's sleeping arrangements (communal vs. familial) on the extent of fathers' involvement in their children's lives and their level of satisfaction from fatherhood. Questionnaires assessing those aspects of fatherhood were administered to 40 fathers living in a kibbutz. Results indicated that the fathers of children sleeping at home were more involved with their children's lives and showed higher levels of satisfaction from fatherhood. Preference for a communal sleeping arrangement for children was expressed among 7 men, all of whom were older than 50 years. These results are discussed in the context of culturally changing concepts of paternal roles in the family and socioeconomic transition in the kibbutz.     

EUTOPIA: THE PROMISE OF BIOTECHNOLOGY AND THE REALIGNMENT OF WESTERN AXIALITY

Abstract. This essay discusses the deep perceptual and social changes that the advanced applications of biotechnology could bring in the West. It examines the probable collapse of a fundamental perceptual bipolarity on which the Western mind and social mobilization have been based since its inception in the West: Athens‐‐Jerusalem. This collapse will quite possibly radically reshape Western perceptions of self and nature and will remodel established constellations and modes of social mobilization and social organization. The radical collapse of the preceding established feature of Western modernity is due to take place in the field of biotechnology, since the latter promises to produce a deliverable perfection of flesh and an equally corporeal personal bliss. I call this promise ``eutopia,'' an actual and tangible utopia‐‐ ``a laboratory on the hill.''
