Moral Judgment in Extreme Social Contexts: Soldiers Who Refuse to Fight and Physicians Who Strike?1

This paper compares two examples of moral action within extreme social contexts: the refusal of Israeli reserve soldiers to perform their military service during the war in Lebanon (1982–1983), and the refusal of Israeli physicians to provide medical care during a “labor war”, that is a strike. This paper examines the cognitive developmental premise that with an increase in the actors' stage of moral development there will be a greater consistency between hypothetical and actual moral reasoning (Kohlberg, 1984). Blasi's (1983) concept of personal integrity, that is, the consistency between the actors' judgment concerning the morality of an action and the action that was actually performed, is examined as well. The findings show that the “refusing” soldiers manifested stage consistency in their action, whereas the physicians failed to justify their action in line with their moral competence. Whereas the soldiers viewed their action as highly moral, the physicians viewed their strike action as unfortunate but necessary. The motivation of the two groups of actors to act in line with their behavioral choices is discussed.     

Develocracy vs democracy

In a sequence of contributions in Developmental Review,(Moshman, 1990a, Moshman 1990b; Commons & Rodriguez, 1990), researchers have recently applied a developmental approach to constitutional policy. In particular, they discussed whether student religious groups in public schools should be permitted in light of the potentially conflicting constitutional principles of religious freedom on the one hand and of the ban against the establishment of a religion by the government on the other hand. Although they differed in important respects, Moshman as well as Commons and Rodriguez made the permissibility of student religious groups fully or partly contingent on the students' developmental stage. Because newer developmental theories differentiate several stages of adult development, such linkage of constitutional rights with developmental stages raises the specter of “develocracy.” Develocracy is a term I suggest to characterize a constitutional system in which a substantial number of rights and duties of adults depends on their developmental stage.     

Fostering equitable consequences from computer learning environments

This article discusses (a) the potential advantages of learning computer programming, (b) the performance of males and females in middle school programming courses, (c) the problems teachers face in achieving this potential, and (d) the participation of males and females in programming courses. Females comprise about 40% of the students enrolled in middle school programming courses. They perform, on the average, as well as or better than the males, and comprise 60% of the most talented students. Significantly, neither males nor females make very much progress in learning to program and, therefore, in acquiring any of the general cognitive skills which might potentially result from programming courses.This material is based upon research supported by the National Institute of Education, Grant No. 400-83-0017.

Some neglected problems in IRT

The paper addresses three neglected questions from IRT. In section 1, the properties of the “measurement” of ability or trait parameters and item difficulty parameters in the Rasch model are discussed. It is shown that the solution to this problem is rather complex and depends both on general assumptions about properties of the item response functions and on assumptions about the available item universe. Section 2 deals with the measurement of individual change or “modifiability” based on a Rasch test. A conditional likelihood approach is presented that yields (a) an ML estimator of modifiability for given item parameters, (b) allows one to test hypotheses about change by means of a Clopper-Pearson confidence interval for the modifiability parameter, or (c) to estimate modifiability jointly with the item parameters. Uniqueness results for all three methods are also presented. In section 3, the Mantel-Haenszel method for detecting DIF is discussed under a novel perspective: What is the most general framework within which the Mantel-Haenszel method correctly detects DIF of a studied item? The answer is that this is a 2PL model where, however, all discrimination parameters are known and the studied item has the same discrimination in both populations. Since these requirements would hardly be satisfied in practical applications, the case of constant discrimination parameters, that is, the Rasch model, is the only realistic framework. A simple Pearsonx ² test for DIF of one studied item is proposed as an alternative to the Mantel-Haenszel test; moreover, this test is generalized to the case of two items simultaneously studied for DIF.     

An extension of the partial credit model with an application to the measurement of change

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.

Relevant deduction

This paper presents an outline of a new theory of relevant deduction which arose from the purpose of solving paradoxes in various fields of analytic philosophy. In distinction to relevance logics, this approach does not replace classical logic by a new one, but distinguishes between relevance and validity. It is argued that irrelevant arguments are, although formally valid, nonsensical and even harmful in practical applications. The basic idea is this: a valid deduction is relevant iff no subformula of the conclusion is replaceable on some of its occurrences by any other formula salva validitate of the deduction. The paper first motivates the approach by showing that four paradoxes seemingly very distant from each other have a common source. Then the exact definition of relevant deduction is given and its logical properties are investigated. An extension to relevance of premises is discussed. Finally the paper presents an overview of its applications in philosophy of science, ethics, cognitive psychology and artificial intelligence.This paper is based on the first part of my habilitation Schurz (1989).

The Impact of Procedural Justice on Opinions of Public Policy: Solid Waste Management as an Example1

This study assessed the applicability of Tyler and Lind's (1992) relational model of authority to the context of local government policies on solid waste management. Tests of the hypothesized relations proposed by Tyler and Lind, accomplished through structural equation modeling, revealed that our data supported the relations between the various constructs of the model. Perceptions of both process control and relational process were found to be positively related to procedural fairness judgments, while procedural fairness judgments were weakly related to evaluations of government entities. Contrary to our expectations, a similar structural equation model test of an extension of the Tyler and Lind model showed that the model constructs were unrelated to respondents' opinions of public policies. The results also indicated that respondents living in communities with different infrastructures and political climates differed slightly in their perceptions of procedural justice and related constructs, but did not differ in their endorsement of the various solid waste management policies.
