A survey on computer use was conducted on 152 college students majoring in elementary education. The students used computers an average of 11.8 hours per week. The uses included academic uses such as writing papers and conducting research over the Internet, as well as leisure uses such as chatting, playing games, and cruising the Web. A strong correlation is seen between the number of hours a student spends on the computer for academics and the number of hours spent on the (...) computer for nonacademics. The students “waste” an average of 4.5 hours per week on the computer, which is less than half the time they spend watching television. (shrink)

Psychologists' emerging interest in spirituality and religion as well as the relevance of each phenomenon to issues of psychological importance requires an understanding of the fundamental characteristics of each construct. On the basis of both historical considerations and a limited but growing empirical literature, we caution against viewing spirituality and religiousness as incompatible and suggest that the common tendency to polarize the terms simply as individual vs. institutional or ′good′ vs. ′bad′ is not fruitful for future research. Also cautioning against (...) the use of restrictive, narrow definitions or overly broad definitions that can rob either construct of its distinctive characteristics, we propose a set of criteria that recognizes the constructs' conceptual similarities and dissimilarities. Rather than trying to force new and likely unsuccessful definitions, we offer these criteria as benchmarks for judging the value of existing definitions. (shrink)

Theological schools are well situated to create intentional cultures for the purpose of spiritual formation. Indeed, most schools of theology have this goal as an essential part of their mission as well as a requirement for continued accreditation. And yet, the measurement of spiritual formation over time is fraught with challenges. This article seeks to address some of these challenges by means of developing a meta-theory of positive change/growth which would eventually serve as a theoretical basis for the development of (...) a generalizable and reliable measurement tool.

Truth diagrams are introduced as a novel graphical representation for propositional logic. To demonstrate their epistemic efficacy a set of 28 concepts are proposed that any comprehensive representation for PL should encompass. TDs address all the criteria whereas seven other existing representations for PL only provide partial coverage. These existing representations are: the linear formula notation, truth tables, a PL specific interpretation of Venn Diagrams, Frege’s conceptual notation, diagrams from Wittgenstein’s Tractatus, Pierce’s alpha graphs and Gardner’s shuttle diagrams. The comparison (...) of the representations succeeds in distinguishing ideas that are fundamental to PL from features of common PL representations that are somewhat arbitrary. (shrink)

In recent years, there has been a particular emphasis placed on conducting randomized controlled trials (RCTs) that compare the relative efficacy of psychosocial and pharmacological interventions. This article addresses relevant ethical considerations in the conduct of these treatment trials, with a focus on RCTs with children. Ethical concerns, including therapeutic misconception, treatment preference, therapeutic equipoise, structure of treatments, and balancing risks versus benefits, are introduced through a clinical scenario and discussed as they relate to psychotherapy versus medication RCTs. In each (...) case, suggestions are made for researchers seeking to minimize the impact of these ethical concerns on research participants. (shrink)

Six characteristics of effective representational systems for conceptual learning in complex domains have been identified. Such representations should: (1) integrate levels of abstraction; (2) combine globally homogeneous with locally heterogeneous representation of concepts; (3) integrate alternative perspectives of the domain; (4) support malleable manipulation of expressions; (5) possess compact procedures; and (6) have uniform procedures. The characteristics were discovered by analysing and evaluating a novel diagrammatic representation that has been invented to support students' comprehension of electricity—AVOW diagrams (Amps, Volts, Ohms, (...) Watts). A task analysis is presented that demonstrates that problem solving using a conventional algebraic approach demands more effort than AVOW diagrams. In an experiment comparing two groups of learners using the alternative approaches, the group using AVOW diagrams learned more than the group using equations and were better able to solve complex transfer problems and questions involving multiple constraints. Analysis of verbal protocols and work scratchings showed that the AVOW diagram group, in contrast to the equations group, acquired a coherently organised network of concepts, learnt effective problem solving procedures, and experienced more positive learning events. The six principles of effective representations were proposed on the basis of these findings. AVOW diagrams are Law Encoding Diagrams, a general class of representations that have been shown to support learning in other scientific domains. (shrink)

Alan Strudler has written a stimulating and provocative article about deception in negotiation. He presents his views, in part, in contrast with our earlier work on the Mutual Trust Perspective. We believe that Strudler is wrong in his account of the ethics of deception in negotiation and in his quick dismissal of the Mutual Trust Perspective. Though his mistakes may be informative, his views are potentially harmful to business practice. In this paper, we present arguments against Strudler’s position and attempt (...) to salvage the Mutual-Trust Perspective from his attack. Strudler’s work reaffirms the need for a more pragmatic approach to business ethics. We close the paper with a renewed call for more constructive and practical approaches to business ethics research.

The representational epistemic approach to the design of visual displays and notation systems advocates encoding the fundamental conceptual structure of a knowledge domain directly in the structure of a representational system. It is claimed that representations so designed will benefit from greater semantic transparency, which enhances comprehension and ease of learning, and plastic generativity, which makes the meaningful manipulation of the representation easier and less error prone. Epistemic principles for encoding fundamental conceptual structures directly in representational schemes are described. The (...) diagrammatic recodification of probability theory is undertaken to demonstrate how the fundamental conceptual structure of a knowledge domain can be analyzed, how the identified conceptual structure may be encoded in a representational system, and the cognitive benefits that follow. An experiment shows the new probability space diagrams are superior to the conventional approach for learning this conceptually challenging topic. (shrink)

A model is presented that addresses both the distribution and comprehension of different forms of referring expressions in language. This model is expressed in a formalism (Kamp & Reyle, 1993) that uses interpretive rules to map syntactic representations onto representations of discourse. Basic interpretive rules are developed for names, pronouns, definite descriptions, and quantified descriptions. These rules are triggered by syntactic input and interact dynamically with representations of discourse to establish reference and coreference. This interaction determines the ease with which (...) coreference can be established for different linguistic forms given the existing discourse context. The performance of the model approximates that observed in studies of intuitive judgments of grammaticality and studies using online measures of language comprehension. The model uses the same basic interpretive mechanisms for coreference within and between sentences, thereby linking the domain traditionally studied by generative linguists to domains that have been of concern primarily to psychologists and computational linguists.

The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments (...) against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work. (shrink)

Historians play it safe. Complex issues are dissected while analytical distance keeps stakeholders at bay. But the relevance of historical research may be lost in caution and failure to engage with a wider audience. We can't afford that. We have too much to offer and too much at stake. We need to take the discussion of science and religion beyond our own professional circles. Peter Harrison's The Territories of Science and Religion gives us an opportunity to do so. We (...) can use his book to understand why people consistently get the relation wrong. However, we need to take the next step ourselves, involve historians in the common academic goal, across disciplines, to make sense of the world around us and make that combined knowledge truly useful. Evolution and natural history might help to that effect. (shrink)

In response to the proposal by Walter Jaeschke contained in the preceding paper, the Nineteenth Century Theology Group of the American Academy of Religion discussed plans, at the annual meeting of the Academy on 15–17 November 1979, to complete a new English study edition of Hegel’s Lectures on the Philosophy of Religion, and has agreed to sponsor its publication by Scholars Press in the AAR Texts & Translations Series. An Editorial Committee has been formed with the following membership: Robert F. (...) Brown, Richard Crouter, James O. Duke, Francis S. Fiorenza, Joseph Fitzer, Peter C. Hodgson, Walter Jaeschke, Darrell Jodock, O. Kem Luther, Dale M. Schlitt, John C. Shelley, James Yerkes. Many of these persons will be involved in the editing and translating process. (shrink)

The aim of this article is to critique health policy discourses that are taken for granted. This perspective will allow for the identification of ‘exclusionary’ health policies, which we define as policies that are thought to offer universal benefit, despite yielding adverse effects for significant groups of people in society. As such, policies that are said to be designed ‘for all’ frequently benefit only a subset of the population. Our intent is to highlight the distributional consequences of certain health policies (...) that are largely institutionalized in contemporary society. We believe that these distributional effects are explicit representations of power in society and that institutions may provide individual ‘choice’ and ‘freedom’ that, in turn, yields separation as an outcome, a separating equilibrium. Specifically, if those who benefit from policies of partition are numerous and are to obtain significant advantage or incur limited costs, or if those who are adversely affected are scarce (or hidden), or the size of these adverse effects are small (or perceived to be minor), then partition becomes more likely as a ‘legitimate’, but exclusionary, instrument of public policy.

Computational models of learning provide an alternative technique for identifying the number and type of chunks used by a subject in a specific task. Results from applying CHREST to chess expertise support the theoretical framework of Cowan and a limit in visual short-term memory capacity of 3–4 looms. An application to learning from diagrams illustrates different identifiable forms of chunk.

This article advocates for the inclusion of theistic beliefs in the study of humility and intellectual humility and recommends the construct of worldview as a promising resource for this endeavor. The promise of this approach is tested by exploring the contrasting worldviews of three religious traditions: Buddhism, Christianity, and atheism. In so doing, the ontological and anthropological turn of these worldviews will be contrasted with implications for research on humility drawn.

How do Christians reconcile their belief in one God with the concept of three divine 'persons'? This Companion provides an overview of how the Christian doctrine of the Trinity has been understood and articulated in the last two thousand years. The Trinitarian theologies of key theologians, from the New Testament to the twentieth century, are carefully examined and the doctrine of the Trinity is brought into dialogue with non-Christian religions as well as with other Christian beliefs. Authors from a range (...) of denominational backgrounds explore the importance of Trinitarian thought, locating the Trinity within the wider context of systematic theology. Contemporary theology has seen a widespread revival of the doctrine of the Trinity and this book incorporates the most recent developments in the scholarship. (shrink)
