On finite approximability of ψ-intermediate logics

The aim of this note is to show (Theorem 1.6) that in each of the cases: = {, }, or {, , }, or {, , } there are uncountably many -intermediate logics which are not finitely approximable. This result together with the results known in literature allow us to conclude (Theorem 2.2) that for each : either all -intermediate logics are finitely approximate or there are uncountably many of them which lack the property.     

Hemingway's Aging Heroes and the Concept of Phronesis

This article explores the concept of phronesis (practical wisdom) in four aging protagonists in Ernest Hemingway's works ranging from the short story A Clean Well-Lighted Place to the novella The Old Man and the Sea. Phronesis represents an understanding of the ways of the world, an acute sensitivity to a critical logic of human existence that can be attained only through extensive experience and suffering. The four aging protagonists are examples of Hemingway's definition of aging productively and profitably by purchasing an inner peace that consists of an intuitive system of continuous adjustment to the exigencies of daily living.     

Distinctions between subgroups of asthmatic children: Parental reactions to experimental separation

Parental reactions to experimental separation were analyzed for two groups of asthmatic children, those for whom behavioral factors were judged highly relevant to asthma and those for whom such factors appeared unimportant. The former group of 13 (predicted positives) had shown a highly significant improvement in asthma during separation from their families; the latter group of 12 (predicted negatives) had not. Coding of standardized interviews conducted around the time of separation disclosed that parents (mothers, especially) of predicted positives scored significantly higher than parents of predicted negatives on such scales as fussing over the child at the time of leave taking, missing child, experiencing pain and discomfort during the separation, being anxious over child's welfare, etc. Psychological test data did not discriminate between the parents' or childrens' groups as clearly as the more focused separation interviews but the test results were consistent with interview differences. The separation elicited very strong emotional reactions from several mothers.This study was supported by United States Public Health Service Grant No. HD01060 from the National Institute of Child Health and Human Development. Kirk Brady, John Means, loan Muser, and Claire Purcell contributed to data collection and/or data analysis.     

Depression and Anxiety in Persons with Parkinson's Disease With and Without “On–Off” Phenomena

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.     

Variations in use of the term “or”

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.     

Sprachverstehende maschinen

In this paper the author tries to disentangle some of the problems tied up in John Searle's famous Chinese-room-argument. In a first step to answer the question what it would be for a system to have not only syntax, but also semantics the author gives a brief account of the functioning of the language understanding systems (LUS) so far developed in the framework of AI research thereby making clear that systems like Winograd's SHRDLU are indeed doing little more than mere number crunching. But things would be entirely different, the author argues, if the database of a LUS were built up by the system itself via some perceptual component-at least, if this perceptual component had the capacity to distinguish objects having a certain property F from objects which do not. For in this case the system could store an internal representation of the fact that the object has the property F in its database if and only if the object in fact has that property. And this would be a good basis for calling such a system a genuine LUS. But Searle has objected to a very similar account of J. Fodor that nothing could be further from true language understanding. The reason for this complaint seems to be that Searle holds the view that a true LUS must e.g., know that the word hamburgers refers to hamburgers and that he moreover claims that this knowledge must be explicit or that the system must be aware of the reference of hamburgers to hamburgers. The author argues that this is asking too much. For it seems plausible to say that a system is able to understand e.g., the word hamburger even if it has only implicit knowledge of the fact that hamburger refers to hamburgers in the sense that it has the capacity to tell hamburgers from non hamburgers and the capacity to bring the word hamburger together just with objects of the former kind.     

Yes,Virginia, Lemons are Yellow

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.

Lösungsstrategien beim Attneaveschen Rateversuch

Zusammenfassung Der Rateversuch von Attneave wurde durch Zulassung freier Ratestrategien modifiziert und der Lösungsvorgang der Rateaufgabe zum Thema einer Untersuchung gemacht. Es zeigte sich, daß die Rateleistung (Position des letzten Fehlers) mit zwei provisorisch gebildeten Strategiemerkmalen kovariiert: der Systematik der Abfolge und dem Verhalten nach einem Fehler. Je weniger systematisch die Reihenfolge überprüfter Flächenelemente ist oder/und je konsequenter die positive Strategie der Suche nach dem Figurverlauf auch nach der Widerlegung von Teilhypothesen beibehalten wird, um so besser ist die Rateleistung. Die Befunde werden kurz diskutiert.     

The Power to Feel Fear and The One to Feel Happiness are the Same

The centre of Adorno's Critical Theory is occupied by the theme of happiness. He speaks of the impaired life, of the unjustness of society, of murderous prejudices, of the atrocities in history, of the dissonance in art, of the unhappy consciousness, because something better can only be described from a point of opposition. Happiness cannot be objectified as possession, it always needs to be experienced subjectively, somatically. (With happiness it is like with truth: One does not have it, one is in it.) Happiness cannot be prescribed and ordered; nothing can be done to guarantee happiness. (Happiness goes beyond doing.) Happiness (like fear) has to do with being open to experience which can overwhelm the self. Sexual and aesthetical experience are models for such overwhelming happiness. The sensation of happiness always is very personal, but in this experience the individual leaves its particularity behind. One has to differentiate between goal and object: Happiness may be a goal, but not it itself, only what obstructs it, can be an object of Critical Theory.     

The liar: What paradox?

Most philosophers believe that the Liar Paradox is semantical in character, and arises from difficulties in the predicate true. The author argues that the paradox is pragmatic, not semantic, and arises from violations of essential conditions that define statement-making speech acts. The author shows that his solution to the paradox will not only handle the classical Liar sentences that are necessarily or intrinsically paradoxical, but also sets of Kripke-sentences that are contingently paradoxical.     

Spirituality in Older Adults: A Cross-Cultural and Interfaith Perspective

The definition of spirituality poses a variety of problems for the development of theory and research, as well as practical problems for persons interested in promoting the spiritual well-being of older adults. Although any definition of spirituality is problematic, a definition is proposed that comes out of the writer's clinical experience and is relevant to his understanding of the aging process in different cultural and religious contexts. Two case studies are presented to illustrate the relevance of the definition to the experience of older persons from different cultural and religious backgrounds. Reflections on the case studies suggest ways that an appropriately trained advocate might have helped the persons in these illustrations make changes in their situations that might have improved the quality of their lives. Material from the case studies is also used to clarify differences among terms such as spirituality, religion, religiosity, and piety. The paper proposes to be a contribution to a theoretical foundation for studying and working with spirituality in older adults.     

The family as portrayed on prime-time television, 1947–1990: Structure and characteristics

Successful family series across four decades of American prime-time television were examined. Family portrayals were defined as either conventional or nonconventional. Conventional families were categorized as couples without children and couples with children. Nonconventional families were categorized as single parent or contrived. Additional family characteristics were also recorded including sex of single parent, reason for singleness, social class status, females employed outside the home, live-ins, race, and whether the presentation was dramatic or comedic. The data show a trend toward more equal presentation of conventional and nonconventional families, few divorced or female single parents, and few minority families. Implications of findings are discussed and future research questions suggested.     

Die Wüste Des Realen: Slavoj Žižek Und Der Deutsche Idealismus

Part of Slavoj iek's philosophical background is located in German idealism. In this article, his relation to German idealism is critically assessed, and the key to this assessment is found in iek's favorite medium: film. In film, reality can only appear as a new image, replacing an old reality as fictitious, the real itself, however, remains unreachable by thought. At this point, a parallel with German idealism appears: it was Kant who turned reality into a desert, and Hegel and Schelling who tried to retrieve it. Siding with Adorno and Heidegger, iek reaches a negative conclusion that does justice to neither German idealism nor indeed Schelling. His use of German idealism is one-sided and selective, regardless of the fact that it allows him to formulate an adequate critique of Western society. Perceiving a parallel between iek's conception of cinema and Kantian imagination [Einbildungskraft], the final conclusion is that he approaches German idealism not in terms of its conceptual system-character, but in terms of sensual multiplicity, not seeking unity in it, but precisely fragmentation.     

Review

Summary Whatever conception of moral philosophy one subscribes to, it is of interest from every standpoint to determine whether and to what extent even exclusively self-interested individuals are prepared to constrain themselves in a way which can be considered moral. Since self-interest is de facto a very strong motive in decisions and behavior, such analyses are significant in two respects. First, they can show how and within which bounds a moral disposition is justifiable even when lacking, e.g., benevolence, a special moral sense, a sense of (objective) value, or any disposition to construct a veil of ignorance, viz. in order to compute an average social utility. In this regard, a kind of minimal morality can be founded on just the assumption that individuals are strictly self-interested, as N. Hoerster (1983) has shown. Secondly such analyses can sharpen one's eyes for those situations in which moral obligations are possibly incurred (and which perhaps even rational egoists may desire), but which cannot really guide behavior in the face of strong self-interest. In this regard, insight into strategies for avoiding or ameliorating problematic situations may be won.     

Reflection-impulsivity and information seeking in emotionally disturbed children

Forty-four emotionally disturbed children were administered the Matching Familiar Figures Test by one examiner after which the 13 most impulsive and 13 most reflective were chosen. A second examiner administered the Fixed Alternatives Question-Asking Game in whichSs sought information by asking questions that could be answered either yes or no. These questions were classified on a developmental basis; reflective children were found to employ more mature questions than did impulsive ones. Indirect comparisons between the present results and those obtained with normalSs were made.     

Effects of sequential 1-minute time trials with and without inter-trial feedback and self-correction on general and special education students' fluency with math facts

We measured the effects of two procedures for implementing 1-min time trials on the rate and accuracy with which elementary students wrote answers to single-digit math facts in two concurrent experiments in a first grade classroom and a special education classroom. On-task behavior of three students in each class was also measured. Baseline was a 10-min work period in which students were told to answer as many problems as you can. The two time trial conditions, each of which was also conducted within a 10-min period, consisted of: (1) a series of seven 1-min time trials with a 20-s rest period following each timing; and (2) two 1-min timings, each followed by a teacher-directed feedback and self-correction activity. Students in both classrooms answered correctly more problems per minute during both time trial conditions than they did during the 10-min work period, with the highest levels of fluency occurring during the two time trials with self-correction. The emphasis on going fast did not impair students' accuracy of performance. In both classrooms the percentage of attempted problems answered correctly was high during the initial baseline and increased slightly over the course of the study. On-task behavior was higher during both time trial conditions than during the 10-min work period. When asked at the study's conclusion which of the three methods for practicing math facts (1) helped you learn the most and (2) would you like to do again, the majority of the students in both classrooms chose the time trials followed by feedback and self-correction.     

The Deep Structure of Group Life: Unconscious Dimensions

There is a reconsideration and renaissance of interest in expanded conceptions of unconscious processes as they affect individuals and groups (Grotstein, 1999). Recent focus on social unconscious (Hopper, 1996) and cultural unconscious processes (Henderson, 1988) and the nature of intersubjectivity (Harwood and Pines, 1998) raise questions about the location of group analysis. This paper considers the deep structure of group life by examining four functions of the unconscious: repressive, conservative, creative, and mythopoetic (Ellenberger, 1970). On an individual level of analysis, these functions are equated respectively with formative ideas about the: personal–subjective, social–political, intersubjective–cultural and collective–objective unconscious. Group level analogs, as they develop and affect groups and their members, are explored as synthetic, shared, symbolicy and synchronous unconscious processes.     

On superintuitionistic logics as fragments of proof logic extensions

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.
