BARROW AND TIPLER'S ANTHROPIC COSMOLOGICAL PRINCIPLE

Abstract. John D. Barrow and Frank J. Tipler's recently published Anthropic Cosmological Principle is an encyclopedic defense of melioristic evolutionary cosmology. They review the history of the idea from ancient times to the present, and defend both a "weak" version, and two "strong" versions of the anthropic principle. I argue the weak version of the anthropic principle is true and important, but that neither of the two strong versions are well grounded in fact. Their "final" anthropic principle is a revision of Teilhard de Chardin's evolutionary cosmology. They rectify Teilhard's factual errors but commit even more serious psychological and religious errors of their own.     

The effects of student gender,race, and achievement on career exploration advice given by canadian preservice teachers

This study investigated the effects of gender, race, and achievement on ratings of appropriateness of occupations and classifications of occupations (people, data, things) suitable for future exploration by ninth-grade students. The subjects (N=125; 106 females, 19 males), advanced undergraduate education students, were each asked to evaluate a case folder in which gender (female, male, not stated), race (Native, non-Native), and achievement (higher average, lower average) were systematically varied. Subjects gave ratings of appropriateness for future exploration of occupations on 5-point Likert-type scales. The occupations rated also represented three classifications (data, people, things), yielding a second dependent variable. Analysis was accomplished using two four-way analyses of variance. The attribute most influencing ratings was achievement. However, the three-way interactions of gender, race, and achievement limit direct interpretation of the data, and suggest that complex combinations of student attributes influence teachers. The limitations of the present study are emphasized; the implications for advising young women and for future research are discussed.     

Governmental research funding and economic distortion

Science and technology are “good” things. Still, there are many good things that should not be done by government and there are many other things that the private sector does far better. Government-funded research and development (R&D) falls into both these categories. Research funding is big business. In 1998, the Department of Health and Human Services received $13.1 billion, the National Aeronautics & Space Administration $9.3 billion, the Department of Energy $5.6 billion, and the National Science Foundation $2.3 billion. Newt Gingrich, still adhering to the Progressive dictum that “government does it better,” is now calling for a doubling of current federal research expenditures. This article will assess the theoretical arguments for government-funded research and examine specific research programs of the Department of Energy and the Environmental Protection Agency. Throughout, I will argue that private property rights, the rule of law, and free markets are the greatest incentives to conduct scientific research; under-investment in R&D is due not to market failure but to the failure to have markets. a public interest group active in economic and environmental public policy issues.

Automated Measurement of Mouse Freezing Behavior and its Use for Quantitative Trait Locus Analysis of Contextual Fear Conditioning in (BALB/cJ × C57BL/6J)F2 Mice

The most commonly measured mouse behavior in fear conditioning tests is freezing. A technical limitation, particularly for genetic studies, is the method of direct observation used for quantifying this response, with the potential for bias or inconsistencies. We report the use of a computerized method based on latency between photobeam interruption measures as a reliable scoring criterion in mice. The different computer measures obtained during contextual fear conditioning tests showed high correlations with hand-scored freezing; r values ranged from 0.87 to 0.94. Previously reported strain differences between C57BL/6J and DBA/2J in context-dependent fear conditioning were also detected by the computer-based system. In addition, the use of computer-scored freezing of 199 (BALB/cJ×C57BL/6J)F₂ mice enabled us to detect a suggestive gender-dependent chromosomal locus for contextual fear conditioning on distal chromosome 8 by QTL analysis. Automation of freeze scoring would significantly increase efficiency and reliability of this learning and memory test.     

The concept of development in vocational theory and intervention

One of the major problems in the vocational literature is the absence of theoretical formulations which deal with development in more than a superficial manner. Specific problems are that (1) key constructs are adapted from developmental theory without proper attention to the conceptual, empirical, and methodological problems involved; (2) little recognition has been accorded to significant changes in developmental theory during the past 15 years, changes which stress the multidimensional, plastic, contextual, and life-span features of development; (3) there is a paucity of adequately designed, contextually sensitive, longitudinal research; and (4) well-established empirical findings of developmental research have been misrepresented or ignored by vocational researchers. It is proposed that a theory of life-span vocational role development must meet the conceptual and methodological requirements of a developmental approach, that it must contain a contextual perspective, and that it must be relational in the sense that it provides for the examination of the “goodness of fit” between individual and contextual developments. The consequences of this viewpoint for vocational intervention are described as a more pronounced focus on events, processes, and life periods which are identified as antecedents of major vocational decisions. Finally, it is observed that vocational intervention should be viewed as a succession of procedures designed to assist the individual, throughout his/her life, to adapt vocational functioning to changing personal situations as well as to changing economic and contextual circumstances.     

Healthy family functioning: What family therapists,priests, and ministers say

This study compared the concepts of healthy family functioning as perceived by family therapists, Roman Catholic priests, and Southern Baptist ministers. The therapists emphasized the importance of individuation and flexibility. In contrast, the ministers placed greater emphasis on family togetherness rather than individuation, and both the ministers and the priests placed greater emphasis on structure and authority rather than flexibility. The implication of these and other findings are discussed.     

The time required to compare extents in various orientations

In Experiment I, Ss compared the lengths of lines that varied in absolute and relative orientation. Their reaction times showed a constant error pattern of which the familiar horizontal-vertical illusion was a special case, but horizontals were underestimated (relative to other slopes) much more than verticals were overestimate. The effect of difference inorientation was not great, though RT did increase significantly as the difference neared 90 deg. Experiment II was similar except that the lengths of lines were compared withthe widths of bars in a grating. In this case, no consistent pattern of constant error emerged, and there was no suggestion that difference in orientation affected RT.     

Pattern redundancy and detection in very short-term memory

A tachistoscopically presented target letter is detected better in a background of redundant items than in nonredundant material. The present experiment extended this finding by showing that detection rate increased systematically across three levels of background letter redundancy. A conclusion based on the earlier findings was that a serial process of letters in memory could not account for the effects of background redundancy on detection accuracy. Contrary to this conclusion, the present analysis showed that detection for semiredundant displays was successfully predicted by two variants of a serial process model. One model assumed that the scan of a letter is faster when the letter is the same as any prior letter scanned in the matrix. The other model assumes that nonredundant letters are processed serially and that redundant letters are processed all at once, i.e., in parallel.
