Distant Causation in <Emphasis Type="Italic">C</Emphasis>+

The action language C+ of Giunchiglia, Lee, Lifschitz, McCain and Turner is a high-level, logical formalism for the representation of domains involving action and change. However, one cannot directly express relationships which hold between states more than one time-step distant, or even say that one action determines another at the next time. We present C+_timed, a generalization of C+ which removes these limitations. As for C+, translations to the language of causal theories are given. We also define a new kind of transition system called a ‘run system’ to provide a graphical semantics. Finally, we show how domains involving prohibition and permission can be modelled, by incorporating the ideas of another extension of C+.     

Representation and Reasoning about Evolutions of the World in the Context of Reasoning about Actions

The first step in reasoning about actions and change involves reasoning about how the world would evolve if a certain action is executed in a certain state. Most research on this assumes the evolution to be only a single step and focus on formulating the transition function that defines changes between states due to actions. In this paper we consider cases where the evolution is more than just a single change between one state and another. This is manifested when the execution of an action may trigger execution of other actions, or when multiple agents act on the environment following certain strategies.     

Psychological Trauma,Christ’s Passion,and the African American Faith Tradition

This article argues that Christ’s passion/crucifixion functioned within the African American psyche as a religious narrative and symbol that uniquely addressed the severe trauma they underwent during the Middle Passage and slavery by enabling them to experience the presence of God in the depths of extreme suffering. Christ’s passion/crucifixion mirrored their experience of racial oppression and, thereby, provided a critique of the system and actors that perpetuated it. The Spiritual “Were You There?” is interpreted in this light. This correspondence between the African American’s historical experience and the narrative symbol of Christ’s passion/crucifixion helps explain their conversion to Christianity.     

IQ stability: the relation between child and young adult intelligence test scores in low-birthweight samples

The stability of IQ from childhood to adulthood in low-birthweight subjects was measured in two independent samples with follow-up intervals of approximately 14 and 9.5 years. In both samples, intelligence was assessed with the WISC at a mean age of 9.5. Twenty-six subjects were retested with the WAIS at a mean age of 23.5, and 78 subjects with the BPP (the Danish Military Draft Board Intelligence Test) at the age of 19.1. Both samples obtained childhood and adult test scores below the expected means. For the Wechsler Verbal, Performance and Full-Scale IQs, the stability quotients were 0.86, 0.86, and 0.89 in the WAIS sample, and the retest correlations for the three IQs with the BPP score were 0.66, 0.65, and 0.74. Thus, the majority of children showed stable patterns of intellectual development from middle childhood to young adulthood.     

Authoritarianism and PoliticalSocialization in the Context of the Arab-Israeli Conflict

This study explored the hypothesis that authoritarianism is negatively associated with peace supportiveness. A sample of 197 Jewish/Israeli university students responded to a questionnaire that included items on attitudes toward the Middle East peace process as well as a personality measure. The results confirmed the hypothesis: Individuals who were less supportive of the peace process were more authoritarian conformists than were supporters of the process. A significant association between religiosity and attitudes toward the peace process was also found; the split between peace supporters and non-supporters corresponded roughly, though not exactly, to the split between religious and non-religious. The pro-peace individual is generally non-religious, less authoritarian conformist, and less aggressive. Hence, the social cognitions studied—beliefs about the peace process—may be group beliefs. Certain characteristics of the groups in question, such as socialization practices and social structure, may account for the personality features that covaried with the beliefs. The data showing that peace attitudes, religiosity, and certain personality traits form one entity might thus be marshalled in discussing the identity issue and applied to other scenes in contemporary conflicts.     

任务难度对基于位置返回抑制时间进程的影响

在返回抑制的实验范式下,采用线索一靶子模式进行了视觉字母觉察实验、实验发现,返回抑制在线索与靶子之间的时间间隔（ＳＯＡ）为７００ｍｓ时出现,且在９００ｍｓ时消退。这与先前许多实验发现的返回抑制在ＳＯＡ为３００ｍｓ左右时出现的结果不一致。作者认为,实验任务的难度是影响返回抑制时间进程的一个重要因素。     

时点,时距和时序信息加工之间相关性研究

本研究分为两个实验,分别采用预期式和回溯式范型,探讨时距、时序和时点三者之间信息加工的相关性,结果发现：同一时间经历,时距估计与时序判断随注意参与程度的增加,由负相关趋势向正相关变化;时距估计与时点离散度可能呈正相关趋势;时序判断与时点离散度随注意参与程度的增加,由负相关趋势向正相关变化。     

A Gabbay-Rule Free Axiomatization of T×W Validity

The semantical structures called T×W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, _O, which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator . However, these structures are also suitable for interpreting an extended language, _SO, containing a further possibility operator ^s which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history simultaneity operator. In the present paper we provide an infinite set of axioms in _SO, which is shown to be strongly complete forT ×W-validity. Von Kutschera (1997) contains a finite axiomatization of T×W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions.
