Do participants bring their own priors to an experiment? If so, do they share the same priors as the researchers who design the experiment? In this article, we examine the extent to which self-generated priors conform to experimenters’ expectations by explicitly asking participants to indicate their own priors in estimating the probability of a variety of events. We find in Study 1 that despite being instructed to follow a uniform distribution, participants appear to have used their own priors, which deviated (...) from the given instructions. Using subjects’ own priors allows us to account better for their responses rather than merely to test the accuracy of their estimates. Implications for the study of judgment and decision making are discussed. (shrink)
I discuss the attitude of Jewish law sources from the 2nd–:5th centuries to the imprecision of measurement. I review a problem that the Talmud refers to, somewhat obscurely, as impossible reduction. This problem arises when a legal rule specifies an object by referring to a maximized (or minimized) measurement function, e.g., when a rule applies to the largest part of a divided whole, or to the first incidence that occurs, etc. A problem that is often mentioned is whether there might (...) be hypothetical situations involving more than one maximal (or minimal) value of the relevant measurement and, given such situations, what is the pertinent legal rule. Presumption of simultaneous occurrences or equally measured values are also a source of embarrassment to modern legal systems, in situations exemplified in the paper, where law determines a preference based on measured values. I contend that the Talmudic sources discussing the problem of impossible reduction were guided by primitive insights compatible with fuzzy logic presentation of the inevitable <span class='Hi'>uncertainty</span> involved in measurement. I maintain that fuzzy models of data are compatible with a positivistic epistemology, which refuses to assume any precision in the extra-conscious world that may not be captured by observation and measurement. I therefore propose this view as the preferred interpretation of the Talmudic notion of impossible reduction. Attributing a fuzzy world view to the Talmudic authorities is meant not only to increase our understanding of the Talmud but, in so doing, also to demonstrate that fuzzy notions are entrenched in our practical reasoning. If Talmudic sages did indeed conceive the results of measurements in terms of fuzzy numbers, then equality between the results of measurements had to be more complicated than crisp equations. The problem of impossible reduction could lie in fuzzy sets with an empty core or whose membership functions were only partly congruent. Reduction is impossible may thus be reconstructed as there is no core to the intersection of two measures. I describe Dirichlet maps for fuzzy measurements of distance as a rough partition of the universe, where for any region A there may be a non-empty set of - _A (upper approximation minus lower approximation), where the problem of impossible reduction applies. This model may easily be combined with probabilistic extention. The possibility of adopting practical decision standards based on -cuts (and therefore applying interval analysis to fuzzy equations) is discussed in this context. I propose to characterize the <span class='Hi'>uncertainty</span> that was presumably capped by the old sages as U-<span class='Hi'>uncertainty</span>, defined, for a non-empty fuzzy set A on the set of real numbers, whose -cuts are intervals of real numbers, as U(A) = 1/h(A) 0 h(A) log [1+(A)]d, where h(A) is the largest membership value obtained by any element of A and (A) is the measure of the -cut of A defined by the Lebesge integral of its characteristic function.

The class of stable posets is defined and investigated. We give a forcing construction of a universe of set theory which satisfies a weak form of Martin's Axiom and $2^{\aleph_0} > \aleph_1$ and yet some propositions which follow from CH hold in this universe.

The study examined the distinction between two traditional work absence measures: frequency, reflecting voluntary absence, and duration, reflecting non-voluntary absence. The two measures were compared in a test of the relationship between work absence and employees’ perceptions of organizational ethics. Questionnaires and archive data were collected from 1,016 teachers in Israel. Organizational ethics was represented by three variables: ethical climate (caring and formal), organizational justice (distributive and procedural), and teacher’s tendency to misbehave. Results showed that four ethical constructs (caring (...) climate, formal climate, tendency to misbehave, and procedural justice) were related to absence frequency, while only one (caring climate) was related to absence duration. The findings add to previous research on the distinction between voluntary and involuntary absence measures, and the superior sensitivity of frequency over duration as a measure of voluntary absence. In practice, the results may encourage principals and managers to create ethical workplaces to minimize absence frequency. (shrink)
This study aimed to elucidate the withdrawal behaviors syndrome (lateness, absence, and intent to leave work) among nurses by examining interrelations between these behaviors and the mediating effect of organizational commitment upon ethical perceptions (caring climate, formal climate, and distributive justice) and withdrawal behaviors. Two-hundred and one nurses from one hospital in northern Israel participated. Data collection was based on questionnaires and hospital records using a two-phase design. The analyses are based on Hierarchical Multiple Regressions and on Structural Equation Modeling (...) with AMOS. Affective commitment was found to mediate the relationship between different dimensions of nurses’ ethical perceptions (caring climate, formal climate, and distributive justice) and their intent to leave work. Lateness was found to be positively related to absence frequency which was found negatively related to intent to leave. Males were late more frequently than females, while seniority was related only to absence frequency. The findings indicated that each withdrawal behavior exhibits unique relationships. The results may help policy makers to focus on improving the ethical environment in order to increase nurses’ commitment and reduce their intent to leave. Improving the ethical environment may be achieved through ethical education for nurses which may promote ethical considerations becoming an integral part of nurses’ work. (shrink)
In this essay I will argue for the existence of a Bolshevik Center, which coordinated the activities of the Bolsheviks in the Russian Social Democratic Party. This Bolshevik Center was dissolved in an intra-Bolshevik factional dispute on the eve of Lenin''s writing hisMaterialism and Empirio-Criticism. The source of the conflict in the Bolshevik Center related to disagreements over Lenin''s tactics following the 1905 revolution. The leader of the anti-Lenin opposition was Bogdanov. But the struggle over tactics could not be contained (...) in the political sphere; it spilled over to the philosophical. Lenin''sMaterialism and Empirio-Criticism was written as a refutation of Bogdanov''s philosophical thought in an attempt to drive him out of the Party. This essay will trace the events which led to the dissolution of the Bolshevik Center.In order to be able to follow the tactical debates a definition of terms to be used throughout this paper would be helpful. In terms of the strategic problems facing the Bolsheviks, as well as members of the Russian Social-Democratic Party (RSDP), in their attitude to theDuma, the word Boycott will refer to those who argued that the Bolsheviks should not participate in theDuma in any capacity. TheBoycottists maintained that the Bolsheviks should not even participate in the elections to theDuma. The wordUltimatism refers to those among the Bolsheviks who wished to participate in the ThirdDuma, but who favored the total obedience of the Russian Social-Democrats who might be elected to theDuma to the Central Committee of the Party.Ultimatism refers to the control and hegemony of the Central Committee over any social-democratic delegates who might win elections to the Third Duma.Otzovism means removing. TheOtzovists were those among the Bolsheviks, who advocated the removal of any social-democratic delegate in the ThirdDuma who disobeyed the directives of the Party Central Committee. Ultimatism andOtzovism concerned questions of Party authority. The Otzovist recommended the expulsion of any delegate in the Duma who abrogated the authority of the Party organs.Boycottism did not deal with questions of Party authority as such, but rather was fundamentally a tactical question: participation or non-participation in theDuma, e.g. parliamentarism vs revolution.

Major Philosophers of Jewish Prayer in the Twentieth Century addresses the troubling questions posed by the modern Jewish worshiper, including such obstacles to prayer as the inability to concentrate on the words and meanings of formal liturgy, the paucity of emotional involvement, the lack of theological conviction, the anthropomorphic and particularly the masculine emphasis of prayer nomenclature, and other matters. In assessing these difficultites, Cohen brings to the reader the writings on prayer of some seminal 20th century Jewish theologians. These (...) include Herman Cohen, Franz Rosenzweig, Avraham Yitzhak, Hoakohen Kook, Mordecai M. Kaplan, R. Arele, Aaron Rote, Elie Munk, Abraham J. Heschel, Jakob J. Petuchowski, Eugene B. Borowitz, and Lawrence A. Hoffman. (shrink)
