Makers' Rights

This paper examines the thesis that human labor creates property rights in or from previously unowned objects by virtue of labor's power to make new things. This thesis is considered for two possible roles: first, as a thesis to which John Locke might have been committed in his writings on property; and second, as a thesis of independent plausibility that could serve as part of a defensible contemporary theory of property rights. Understanding Locke as committed to the thesis of makers' rights has seemed to many of the best known recent Locke scholars to explain and unify Locke's various claims about property in a way that more traditional labor-mixing interpretations cannot. This paper argues that there is in fact no convincing evidence in Locke's texts to suggest any commitment to the thesis of makers' rights for humans. Further, not only does a version of the traditional labor-mixing argument yield a much superior interpretation of Locke's writings, it is an argument that is far more convincing than makers' rights arguments, quite independent of its usefulness in the interpretation of Locke's theory.     

Fostering Creativity in Philosophy

The American Philosophical Association suggests that studying philosophy can have an important impact on one's creative thinking ability. This paper abstracts from the empirical research on creativity a reasonable model of creative thinking, and discusses what the account implies about fostering creative thinking in philosophy courses. Given the empirical research on creativity and the nature of philosophy, studying philosophy can have an important impact on one's creative thinking ability, but faculty need to focus on it in their courses.

Bull's Theorem by the Method of Diagrams

We show how to use diagrams in order to obtain straightforward completeness theorems for extensions of K4.3 and a very simple and constructive proof of Bull's theorem: every normal extension of S4.3 has the finite model property.     

An approach to integrating “professional responsibility” in engineering into the capstone design experience

ABET 2000 Criteria encourages development of proficiency in professional responsibility in engineering as part of the undergraduate curriculum. This paper discusses the use of industrially sponsored capstone design projects to encourage active discussion of professional responsibility in engineering that naturally occurs during the engineering design process. The paper also discusses student participation in designing responses and approaches to issues such as engineering ethics. The paper includes specific examples of topics addressed by students and the approaches developed (by students) in addressing these issues. An earlier version of this paper was presented at the International Conference on Ethics in Engineering and Computer Science, Case Western Reserve University, Cleveland, March 21–24, 1999.     

ADOLESCENT IDENTITY FORMATION VERSUS SPIRITUAL TRANSFORMATION

Since 1950, Erik Erikson's emphasis on ego-identity formation as the crucial task of adolescence has been the framework for almost all subsequent research and programming to empower positive adolescent development. Chatlos has recently described a “Framework of Spirituality” and contends that identity formation significantly interferes with and should occur after a spiritual transformational process for optimal and more meaningful adolescent development. This article reviews the current status of research in identity formation, including religious and spiritual identity formation contributing to his conclusion, and describes the spiritual transformational process that is proposed to be central to positive adolescent development. A possible link between systemic focus on identity formation and current social upheaval is also identified.     

Does the Exclusion Argument Put Any Pressure on Dualism?

The exclusion argument is widely thought to put considerable pressure on dualism, if not to refute it outright. We argue to the contrary that, whether or not their position is ultimately true, dualists have a plausible response. The response focuses on the notion of ‘distinctness’ that is employed to distinguish between mental and physical properties: if ‘distinctness’ is understood in one way, the exclusion principle on which the argument rests can be denied by the dualist; if it is understood in another way, the argument is not persuasive.     

Cognitive Error Questionnaire (CEQ): Psychometric Properties and Factor Structure of the German Translation

A central component of Beck et al.’s (1979) cognitive theory of depression is faulty information processing reflected by so-called cognitive errors. These cognitive errors are the reason why depressed individuals systematically misinterpret the significance of events in a negative way. They are usually assessed with the application of the Cognitive Error Questionnaire (CEQ). This study examines the psychometric properties and factor structure of the German version of the CEQ in a sample of 796 volunteers at a German university. Results confirmed that the German CEQ has satisfactory to very good psychometric properties, like the American original. Confirmatory factor analyses demonstrated that a hierarchical four-factor model with four subscales and 1 s order factor fits the data best. Therefore, besides using the German CEQ in studies with German-speaking samples, the similarities in psychometric properties of the American and German CEQ allow for cross-cultural studies.     

Distributive Full Lambek Calculus Has the Finite Model Property

We prove the Finite Model Property (FMP) for Distributive Full Lambek Calculus (DFL) whose algebraic semantics is the class of distributive residuated lattices (DRL). The problem was left open in [8, 5]. We use the method of nuclei and quasi–embedding in the style of [10, 1]. Presented by Daniele Mundici.     

Plagiarism: Words and Ideas

Plagiarism is a crime against academy. It deceives readers, hurts plagiarized authors, and gets the plagiarist undeserved benefits. However, even though these arguments do show that copying other people's intellectual contribution is wrong, they do not apply to the copying of words. Copying a few sentences that contain no original idea (e.g. in the introduction) is of marginal importance compared to stealing the ideas of others. The two must be clearly distinguished, and the 'plagiarism' label should not be used for deeds which are very different in nature and importance.
