The partial credit model is considered under the assumption of a certain linear decomposition of the item × category parameters ih into basic parameters j. This model is referred to as the linear partial credit model. A conditional maximum likelihood algorithm for estimation of the j is presented, based on (a) recurrences for the combinatorial functions involved, and (b) using a quasi-Newton approach, the so-called Broyden-Fletcher-Goldfarb-Shanno (BFGS) method; (a) guarantees numerically stable results, (b) avoids the direct computation of the Hesse matrix, yet produces a sequence of certain positive definite matricesB k ,k=1, 2, ..., converging to the asymptotic variance-covariance matrix of the . The practicality of these numerical methods is demonstrated both by means of simulations and of an empirical application to the measurement of treatment effects in patients with psychosomatic disorders.The authors thank one anonymous reviewer for his constructive comments. Moreover, they thankfully acknowledge financial support by the Österreichische Nationalbank (Austrian National Bank) under Grant No. 3720.  相似文献

Out of a personal struggle to understand and help a chronically ill friend the writer evolves a view of the pastor as enabler. The definition of enable, the role of the enabler, and the problems which prevent many from being enabled, are discussed. These definitions are illuminated by the Biblical perspective of Elihu in the book ofJob. The pastor who sees himself as enabler is able to bring perspective, clarity, empathy, compassion, and concrete help to the person in need.Chaplain Rusnak is a graduate of The Luthern School of Theology at Chicago.  相似文献

In experimental game-theoretic research, to the extent that sex has been considered at all, the approach has been to focus on the individual level of analysis. This paper reports the results of experiments designed to focus on sex/gender and to expand the level of analysis to include the institutional level. An asymmetric game was designed such that players in the male and female institutional locations had 3 and 2 alternatives, respectively. Players earned the institutional locations based on a test, so that top and bottom scorers respectively merited the 3- and 2-alternatives locations. Game-theoretic understandings of sex-of-player were compared to the expectations states theory concept of sex status; that is, men expect and are expected to perform more competently than women. Results indicated that top-scorer men and women behave similarly; bottom-scorer men resist their low merit status (behaving the most rationally of all player groups); bottom-scorer women accept their low merit status (behaving the most irrationally of all player groups). Whereas game theory cannot provide a coherent understanding of these findings, the concept of sex status helps to interpret the behavior of all four player groups and shows how judgments about rationality and irrationality depend critically on the interpretive framework used.  相似文献

The main result of this paper belongs to the field of the comparative study of program verification methods as well as to the field called nonstandard logics of programs. We compare the program verifying powers of various well-known temporal logics of programs, one of which is the Intermittent Assertions Method, denoted as Bur. Bur is based on one of the simplest modal logics called S5 or sometime-logic. We will see that the minor change in this background modal logic increases the program verifying power of Bur. The change can be described either technically as replacing the reflexive version of S5 with an irreflexive version, or intuitively as using the modality some-other-time instead of sometime. Some insights into the nature of computational induction and its variants are also obtained.This project was supported by the Hungarian National Foundation for Scientific Research, Grant No. 1810.  相似文献

The continuing debate between utilitarians and deontologists often takes the form of disagreement over how particular moral dilemmas are to be resolved, but protagonists on both sides tend to overlook the possibility of resolving a dilemma with remainder, such as regret. The importance of remainder is also overlooked by critics of some absolutist ways of resolving or slipping between the horns of certain moral dilemmas. Moreover, deontologists, if not utilitarians, can be criticised for overlooking the possibility that, according to their theory, some dilemmas may be irresolvable. Virtue ethics, with its concentration on the agent, readily accommodates both mention of remainder and irresolvable dilemmas, and yields a specification of tragic dilemmas which the other two theories might like to take on.  相似文献

We give sound and complete tableau and sequent calculi for the prepositional normal modal logics S4.04, K4B and G 0(these logics are the smallest normal modal logics containing K and the schemata A A, A A and A ( A); A A and AA; A A and ((A A) A) A resp.) with the following properties: the calculi for S4.04 and G 0are cut-free and have the interpolation property, the calculus for K4B contains a restricted version of the cut-rule, the so-called analytical cut-rule.In addition we show that G 0is not compact (and therefore not canonical), and we proof with the tableau-method that G 0is characterised by the class of all finite, (transitive) trees of degenerate or simple clusters of worlds; therefore G 0is decidable and also characterised by the class of all frames for G 0.Research supported by Fonds zur Förderung der wissenschaftlichen Forschung, project number P8495-PHY.Presented by W.

“Some more” notes,toward a “third” sophistic   总被引:1,自引:0,他引:1  
Historians of rhetoric refer to two Sophistics, one in the 5th century B.C. and another c. 2nd century A.D. Besides these two, there is a 3rd Sophistic, but it is not necessarily sequential. (The 3rd is counter to counting sequentially.) Whereas the representative Sophists of the 1st Sophistic is Protagoras, and the second, Aeschines, the representative sophists of the 3rd are Gorgias (as proto-Third) and Friedrich Nietzsche, Jean-François Lyotard, Michel Foucault, Jacques Lacan, and Paul de Man.To distinguish between and among Socrates, Plato, and Aristotle, and then Protagoras, Gorgias, and Lacan, the author determines how far each of these personages can count. The model of counting, used semiotically across the topoi of possible/impossible, is that of the people of New Guinea: one thing, two things, many things. It is determined (generally) that the philosophers, including Aristotle, count to one; the Sophists to two; and Gorgias, Lacan, and Lyotard, et al. count to many things, thereby breaking up a monism or binarism. The ancient philosophers employ a substratum of probability to hold together the contraries of possible/impossible; the Sophists employ anti/logic, which keeps the contraries/antitheses separate and therefore without synthesis, but which eventually threatens the integrity of the substratum, or the law of non-contradiction; and Gorgias, Lacan, Lyotard et al. theorize about the impossibility/Resistance of the Logos (reason, logic, law, argumentation, history) to Theory/Totalization, because of the Gorgian Kairos and the Lacanian Real — both of which enter the Logos and break up the cycle of the antitheses and create something new, irrational (Untersteiner).This breaking up has a negative/positive influence on Protagoras's man-measure doctrine, which in turn has a similar influence on the problem of the ethical subject. The subject/agent not only no longer knows (by way of Logos) but also no longer acts (as independent agent); the subject becomes a function of Logos as determined by Kairos/Real; it moves from a hypotaxis/syntaxis of one and two to a radical parataxis/paralogy of some more.From the Impossibility/tragedy of knowledge, however, comes the Possible, or Possibilisms, which allows for the new (though divided) ethical subject to reclaim its position as individual. Such a reclamation of the subject, however, has a profound effect on argumentation, and especially the notion of consensus. What is wanted, then, in a Third Sophistic ethical — as opposed to a political — rhetoric is dissensus through radical parataxes and paralogies.  相似文献

Branching-time temporal logics have proved to be an extraordinarily successful tool in the formal specification and verification of distributed systems. Much of their success stems from the tractability of the model checking problem for the branching time logic CTL, which has made it possible to implement tools that allow designers to automatically verify that systems satisfy requirements expressed in CTL. Recently, CTL was generalised by Alur, Henzinger, and Kupferman in a logic known as Alternating-time Temporal Logic (ATL). The key insight in ATL is that the path quantifiers of CTL could be replaced by cooperation modalities, of the form , where is a set of agents. The intended interpretation of an ATL formula is that the agents can cooperate to ensure that holds (equivalently, that have a winning strategy for ). In this paper, we extend ATL with knowledge modalities, of the kind made popular in the work of Fagin, Halpern, Moses, Vardi and colleagues. Combining these knowledge modalities with ATL, it becomes possible to express such properties as group can cooperate to bring about iff it is common knowledge in that . The resulting logic — Alternating-time Temporal Epistemic Logic (ATEL) — shares the tractability of model checking with its ATL parent, and is a succinct and expressive language for reasoning about game-like multiagent systems.  相似文献

Basic Predicate Logic, BQC, is a proper subsystem of Intuitionistic Predicate Logic, IQC. For every formula in the language {, , , , , , }, we associate two sequences of formulas 0,1,... and 0,1,... in the same language. We prove that for every sequent , there are natural numbers m, n, such that IQC , iff BQC n m. Some applications of this translation are mentioned.  相似文献

This paper thematizes the operative kinaesthetic style of world-experiencing life by turning to the ongoing how of our habitual bodily comportment: to our deeply sedimented way(s) of making a body; to schematic inner vectors or tendencies toward movement that persist as bodily ghost gestures even if one is not making the larger, visible gestures they imply; and to inadvertent isometrics, i.e., persisting patterns of trying, bracing, freezing, etc. All such micromovements witness to our sociality insofar as they are not only socially shaped, but perpetuate certain styles of intercorporeal interaction and sustain certain modes of responsivity. Reactivating the sediment -- retrieving the tacit choreography of everyday life from its anonymity and sensing our ongoing ways of living out the legacy of our communal body -- not only allows one's individual bodily style to shift, but can open new possibilities for healthy interkinaesthetic comportment. Such work can thus contribute to an embodied ethics in both theory and practice.  相似文献

Aspects of language pragmatics and the social perception of lying   总被引:1,自引:0,他引:1  
Two experiments were conducted in order to examine the influence of linguistic and extralinguistic variables on the attribution of lying. In the first experiment, one of two tape recordings of a target person, who responded either true or false to a list of adjectives, was evaluated by 83 subjects. The subjects' task was to attempt to discover when the target person was not telling the truth. The stimulus tapes were constructed such that the time between the adjective and the target person's response was systematically varied and the adjectives varied on the likability of a person possessing that trait. Overall, it was found that if the target person responded either too quickly or too slowly the subjects attributed his response as a lie more often than if the delay was more intermediate in duration (p<0.01). The adjective likability value in combination with the true or false response of the target person also contributed to the attribution of lying (p<0.01). In the second experiment, the adjectives were rescaled on another dimension thought to influence the attribution of lying: the degree to which the adjective is true of the general population. The results suggest that this new scale is related to the degree to which lie attributions are made.This research was supported in part by the National Institute of Child Health and Human Development under Research Grant 1 P01 HD-01762-01 and the National Institute of Mental Health under Research Grant MN 08260.  相似文献

The use of poetry during the process of existential psychotherapy with couples and families is described and illustrated. In this approach, poems can be utilized to help the couple and/or family notice meaning potentials in the future, actualize and make use of such meaning potentials in the here and now, and re-collect and honor meanings previously actualized and deposited in the past.  相似文献

Given Time and the Gift of Life explores the following nexus in Derrida's thought: the gift, the mother, and life. The first section examines life within the trajectory of the gift, the excess of gift over return in the gift of life, and the rewriting of Aristotelian generation in differantial species-being. The second section shows the quasi-transcendental nature of Derrida's thought. The conclusion sketches some of the political consequences of the gift of life thought as the quasi-transcendental gift of differantial species-being.  相似文献

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

Our work at the interface of psychology and religion can proceed in two complementary directions. When reading a psychological theory, (1) we may pay special attention to how certain concepts in particular, and the system of ideas as a whole, are being or might be used to interpret religious phenomena. We may focus on how those ideas may be involved in doing psychology of religion: the psychological interpretation of religious phenomena. Alternatively, (2) we may pay special attention to how certain concepts in particular, and the system of ideas as a whole, are being or might be used, either implicitly or explicitly, to make claims about human nature, about the meaning and purpose of life, about God. We may identify the psychology as religion-theology: psychological ideas potentially functioning in a religious-theological manner. I will illustrate this by: (a) examining D. W. Winnicott's article, Transitional Objects and Transitional Phenomena (1953/1986) in terms of three successive concepts or categories: transitional object, transitional phenomena, and a third intermediate area of experiencing; (b) considering how these categories can be used in psychology of religion; (c) reconsidering how the psychological categories may function as religious-theological. The discussion is intended to illustrate how we might more fully appreciate how and why a psychological theory may work well in doing psychology of religion when we more fully appreciate how that psychology implicitly functions as theology.  相似文献

The medicalization of deviance refers to the identification as diseases or illnesses of patterns of behavior that were previously considered in moral terms. Herbert Spencer viewed society as analogous to a living organism. A problem or disease in one part of the organism affects the entire organism. Early sociologists built on this idea and arrived at the conclusion that deviant behavior could be thought of as social disease and social pathology. The early social pathologists were concerned with crime, mental illness, drug abuse, and suicide. There is a tendency to treat such ailments in a hospital or clinical setting. The medicalization of deviance removes responsibility from the individual as well as from the society which continues to produce the problem. Treatment programs give the false impression that something worthwhile is being done about society's behavioral problems and turn the individuals treated back into the same social milieu in which the problem was incubated in the first place. The medicalization of deviance creates a vested-interest industry dependent upon the treatment of individuals. It has constructed a system of individualized microlevel treatment programs that can be beneficial on a limited basis for a few individuals and their families, but it tends to treat only the symptoms but not change the society of which they are but emanations.  相似文献

This study empirically examined the relationship between the expletives, bitch and bastard, and sex-role stereotyping. The expletives were rated by 68 men and 68 women on 80 trait adjectives as to how typical or characteristic each trait was of the stereotypic bitch or bastard in our society. The sex-role implications of the 10 trait terms judged most characteristic of each expletive were then examined. For male subjects, the most distinguishing feature between the two expletives was the inclusion of the stereotypically masculine trait dominant, in their characterization of bitch. Female subjects, on the other hand, did not ascribe such opposite sex-role stereotype traits to bitch, but rather emphasized stereotypically masculine traits in their characterization of bastard. These results are discussed in terms of the regulatory and expressive nature of language, as well as the differential sanction value of the terms bitch and bastard for out-of-role behavior.  相似文献
