On–off phenomena in Parkinson's disease (PD) are unpredictable motor fluctuations associated with long-term levodopa use. Mood fluctuations have been found to coincide with the motor fluctuations in that depression and anxiety increase while the person with PD is in the off state. What has been relatively unexplored is whether those persons with PD who have on–off phenomena differ psychologically in fundamental ways from those who do not have on–off phenomena. In the present study, depression and anxiety symptoms were assessed in 36 persons with PD (n = 14 with on–off phenomena, n = 22 without on–off phenomena). All those with on–off phenomena were assessed in their on state. Those persons with PD with on–off phenomena had significantly higher levels of anxiety than those without on–off phenomena. However, both groups, regardless of on–off status, were mildly depressed. Neurobiological interpretations of the results implicate the locus coeruleus in the pathogenesis of both on–off phenomena and anxiety, whereas psychological interpretations of the results involve the issues of learned helplessness and control over health symptoms in PD.  相似文献

This paper discusses a number of themes and arguments in The Quest for Reality: Stroud's distinction between philosophical and ordinary questions about reality; the similarity he finds between the view that coloris unreal and the view that it is subjective; his argument against thesecondary quality theory; his argument against the error theory; and the disappointing conclusion of the book.  相似文献

An analytical review of the literature revealed four basic hypotheses that have been adopted by researchers investigating Black women and their relationships. The hypotheses have been identified by the author as follows: The weakening hypothesis, the double whammy hypothesis, the Black matriarchy hypothesis, and the Black racism hypothesis. In addition, a discussion of the implication that the hypotheses have for Black and White researchers was given. Finally, suggestions for new approaches and directions that future research should take were included.  相似文献

Male biases are known to exist in the usage, evaluation, and interpretation of masculine generics. This study explored, by means of a tachistoscope, sex-specific biases in visual images evoked by masculine (All men are created equal, At university a student can study whatever he wants) and feminine (The feminists protested outside the town hall, At university a student can study whatever she wants) generics. Photographs of male and female faces were presented in a deliberately ambiguous (subthreshold) viewing field while maintaining the masculine or feminine generic sentence on constant view. It was predicted and found in a sample of 48 university students that if generics invoked sex-specific images, the images would affect the direction in which the viewer would resolve the ambiguous faces, resulting in more reported male faces in the masculine than in the feminine generic condition.Preparation of this article was supported by a New Zealand Social Sciences Research Fund Committee grant (8632/21/24/8604) to S.

This paper illustrates the apparently providential timing and the healing character of near-death experiences (NDEs) and NDE-like episodes, through four case histories of persons whose lives, prior to their experiences, were marked by deep anguish and a sense of hopelessness. Spiritually, such case histories suggest the intervention of a guiding intelligence that confers a form of amazing grace on the recipient. Methodologically, these reports point to the importance of taking into account the person's life history as a context for understanding the full significance of NDEs and similar awakening experiences. The article ends with a retrospective account of a childhood NDE in which the big secret of these experiences is disclosed.We who are about to die demand a miracle. W. H.

Latent trait models for binary responses to a set of test items are considered from the point of view of estimating latent trait parameters=( 1, , n ) and item parameters=( 1, , k ), where j may be vector valued. With considered a random sample from a prior distribution with parameter, the estimation of (, ) is studied under the theory of the EM algorithm. An example and computational details are presented for the Rasch model.This work was supported by Contract No. N00014-81-K-0265, Modification No. P00002, from Personnel and Training Research Programs, Psychological Sciences Division, Office of Naval Research.

A nonempty sequence T1,...,Tn of theories is tolerant, if there are consistent theories T 1 + ,..., T n + such that for each 1 i n, T i + is an extension of Ti in the same language and, if i n, T i + interprets T i+1 + . We consider a propositional language with the modality , the arity of which is not fixed, and axiomatically define in this language the decidable logics TOL and TOL. It is shown that TOL (resp. TOL) yields exactly the schemata of PA-provable (resp. true) arithmetical sentences, if (A1,..., An) is understood as (a formalization of) PA+A1, ..., PA+An is tolerant.  相似文献

Historiography of education is not only a question of construction but also of selection. In 19th century history of education was typically a genre of great educators, mostly male and only marginally female. This construct is influential up to now, at least in popular contexts of educational reasoning. The article discusses in the introductory section problems of selection of names and meanings within history of education, and then three types of historiographical writing that are not only concerned with great educators but have larger Philosophical impact. The first type is Herman Nohls history of German progressive education, the second one is Emile Durkheims history of Higher Education in France, and the third one is George Herbert Meads Movements of Thought in 19th Century. The article compares them and discusses their implications for further development of historical writing in education.  相似文献

Several of the so-called fallacies in Aristotle are not in fact mistaken inference-types, but mistakes or breaches of rules in the questioning games which were practiced in the Academy and in the Lyceum. Hence the entire Aristotelian theory of fallacies ought to be studied by reference to the author's interrogative model of inquiry, based on his theory of questions and answers, rather than as a part of the theory of inference. Most of the fallacies mentioned by Aristotle can in fact be diagnosed by means of the interrogative model, including petitio principii, multiple questions, babbling, etc., and so can Aristotle's alleged anticipation of the fallacy of argumentum ad hominem. The entire Aristotelian conception of inquiry is an interrogative one. Deductive conclusions caught Aristotle's attention in the form of answers that every rational interlocutor must give, assuming only his own earlier answers. Several features of Aristotle's methodology can be understood by means of the interrogative model, including the role of endoxa in it. Theoretically, there is also considerable leeway as to whether fallacies are conceived of as mistakes in questioning or as breaches of the rules that govern questioning games.  相似文献

The notion of monadic three-valued ukasiewicz algebras was introduced by L. Monteiro ([12], [14]) as a generalization of monadic Boolean algebras. A. Monteiro ([9], [10]) and later L. Monteiro and L. Gonzalez Coppola [17] obtained a method for the construction of a three-valued ukasiewicz algebra from a monadic Boolea algebra. In this note we give the construction of a monadic three-valued ukasiewicz algebra from a Boolean algebra B where we have defined two quantification operations and * such that *x=*x (where *x=-*-x). In this case we shall say that and * commutes. If B is finite and is an existential quantifier over B, we shall show how to obtain all the existential quantifiers * which commute with .Taking into account R. Mayet [3] we also construct a monadic three-valued ukasiewicz algebra from a monadic Boolean algebra B and a monadic ideal I of B. The most essential results of the present paper will be submitted to the XXXIX Annual Meeting of the Unión Matemática Argentina (October 1989, Rosario, Argentina).  相似文献

Engendering family life is a spiritual process (theosis) based on human ethological constants of gender difference and generational turnover. Recent studies on ethnicity suggest that such a process retrieves a primordial sense of the human species as a whole, humankind. Families, especially in this broad sense, link together the living and the dead and, at their best, morally empower individuals who link their destinies to such a vision of creation and human health. Reference is made to work on human strengths and speciation by Erik Erikson and to that on maternal thinking by Sara Ruddick. A political program by which an ideology of familism can be made is offered.He is also Chairman of the Board of Management, Campus Kindergarten Company (Australia), Pty. Ltd.  相似文献

Harry Frankfurt's early work makes an important distinction between moral responsibility and free will. Frankfurt begins by focusing on the notion of responsibility, as supplying counterexamples to the principle of alternative possibilities; he then turns to an apparently independent account of free will, in terms of his well-known hierarchy of desires. But the two notions seem to reestablish contact in Frankfurt's later discussion of issues and cases. The present article sets up a putative Frankfurtian account of moral responsibility that involves the potential for free will, as suggested by some of Frankfurt's later remarks about taking responsibility. While correcting what seem to be some common misinterpretations of Frankfurt's view, the article attempts to extract some reasons for dissatisfaction with it from consideration of cases of unfreedom, particularly cases involving addiction.  相似文献

The logic of an ought operator O is contranegative with respect to an underlying preference relation if it satisfies the property Op & (¬p)(¬q) Oq. Here the condition that is interpolative ((p (pq) q) (q (pq) p)) is shown to be necessary and sufficient for all -contranegative preference relations to satisfy the plausible deontic postulates agglomeration (Op & OqO(p&q)) and disjunctive division (O(p&q) Op Oq).  相似文献

Coming fromI andCl, i.e. from intuitionistic and classical propositional calculi with the substitution rule postulated, and using the sign to add a new connective there have been considered here: Grzegorozyk's logicGrz, the proof logicG and the proof-intuitionistic logicI set up correspondingly by the calculiFor any calculus we denote by the set of all formulae of the calculus and by the lattice of all logics that are the extensions of the logic of the calculus, i.e. sets of formulae containing the axioms of and closed with respect to its rules of inference. In the logiclG the sign is decoded as follows: A = (A & A). The result of placing in the formulaA before each of its subformula is denoted byTrA. The maps are defined (in the definitions of x and the decoding of is meant), by virtue of which the diagram is constructedIn this diagram the maps, x and are isomorphisms, thereforex –1 = ; and the maps and are the semilattice epimorphisms that are not commutative with lattice operation +. Besides, the given diagram is commutative, and the next equalities take place: –1 = –1 and = –1 x. The latter implies in particular that any superintuitionistic logic is a superintuitionistic fragment of some proof logic extension.  相似文献

David Lewis, Stewart Cohen, and Keith DeRose have proposed that sentences of the form S knows P are indexical, and therefore differ in truth value from one context to another.1 On their indexical contextualism, the truth value of S knows P is determined by whether S meets the epistemic standards of the speakers context. I will not be concerned with relational forms of contextualism, according to which the truth value of S knows P is determined by the standards of the subject Ss context, regardless of the standards applying to the speaker making the knowledge claim. Relational contextualism is a form of normative relativism. Indexical contextualism is a semantic theory. When the subject is the speaker, as when S is the first person pronoun I, the two forms of contextualism coincide. But otherwise, they diverge. I critically examine the principal arguments for indexicalism, detail linguistic evidence against it, and suggest a pragmatic alternative.  相似文献

The English good and intensifier is discussed as an example of a form that is acceptable even though ungrammatical, both synchronically and diachronically. The construction is analyzed as a case of creative analogy: the extension of a grammatically generated form to a new function, one for which it has no direct grammatical justification. From the perspective of a dynamic theory of language acquisition and evolution, it is argued that such forms constitute a new sort of evidence regarding the nature of language universals.Previous versions of this work were presented to the LSA summer meetings in 1974 and in Carroll (1975, 1978).  相似文献

Two studies showed that adults' responses to questions involving the term or varied markedly depending upon the type of question presented. When presented with various objects (A's and B's) and asked to circle all things which are A or B subjects tended to circle A's as well as B's, whereas when asked to circle all the A's or B's subjects showed a relatively stronger tendency to circle one or the other. Moreover the nature of the sets of objects (As and Bs) influenced behavior as well. There was also evidence that the effects due to question wording or set type transferred.  相似文献
