Plato's Analogy of Soul and State

In Part I of this paper, I argue that the arguments Plato offers for the tripartition of the soul are founded upon an equivocation, and that each of the valid options by which Plato might remove the equivocation will not produce a tripartite soul. In Part II, I argue that Plato is not wholly committed to an analogy of soul and state that would require either a tripartite state or a tripartite soul for the analogy to hold. It follows that the heart of the analogy is not to be found in the comparison of the Kallipolis and its three parts to the soul conceived as tripartite, but rather must be supposed to reside in some other connection between the ways in which justice characterizes states and souls, and I will suggest what this other connection consists in.     

Critiques of Casuistry and Why They Are Mistaken

Casuistic methods of reasoning in medical ethics have been criticized by a number of authors. At least five main objections to casuistry have been put forward: (1) it requires a uniformity of views that is not present in contemporary pluralistic society; (2) it cannot achieve consensus on controversial issues; (3) it is unable to examine critically intuitions about cases; (4) it yields different conclusions about cases when alternative paradigms are chosen; and (5) it cannot articulate the grounds of its conclusions. Two main versions of casuistry have been put forward, and the responses to these objections depend in part on which version one is defending. Jonsen has advocated a version modeled on the approach to casuistry used by moral theologians in the 15th and 16th century, involving comparison of the case at hand with a single paradigm and a lineup of cases. The present author has advocated another version, drawn from experience with cases in clinical ethics, which involves comparing the case at hand with two or more paradigms. Four of the five objections are unsuccessful when directed against Jonsen'sapproach, and all of them are unsuccessful when directed against the approach involving comparison with two or more paradigms.

External analyses of preference models

Using Carroll's external analysis, several studies have found that unfolding models account for more, although seldom significantly more, variance in preferences than Tucker's vector model. In studies of sociometric ratings and political preferences, the unfolding model again rarely outpredicted the vector model by a significant amount. Yet on cross-validation, the unfolding model consistently accounted for more variance. Results suggest that sometimes significance tests are less sensitive than cross-validation procedures to the small but consistent superiority of the unfolding model. Future researchers may wish to use significance tests and cross-validation techniques in comparing models.     

Gasoline conservation: a procedure for measuring and reducing the driving of college students

The study sought to motivate college students to reduce the number of miles they drove each day and thus save gasoline. Students in two psychology classes were divided by class into two groups. The experimental group was offered various combinations of prizes such as cash, a tour of a mental-health facility, car servicing, and a university parking sticker for reducing driving. The value of the prize received was scaled in terms of per cent reduction in driving. The contrast group received no inducements. The condition in which the experimental group's mileage reduction was reinforced was counterbalanced by two baseline conditions. Several special recording procedures were used to reduce and detect the possibility of subjects altering their odometers, the source of the driving data. Experimental subjects reduced their average daily mileage by 20% relative to the initial baseline; the contrast group did not change. During the one-month reinforcement condition, the 12 experimental subjects saved some 170 gallons (worth $102) of gasoline.     

Maximum likelihood estimation of multivariate polyserial and polychoric correlation coefficients

The method of finding the maximum likelihood estimates of the parameters in a multivariate normal model with some of the component variables observable only in polytomous form is developed. The main stratagem used is a reparameterization which converts the corresponding log likelihood function to an easily handled one. The maximum likelihood estimates are found by a Fletcher-Powell algorithm, and their standard error estimates are obtained from the information matrix. When the dimension of the random vector observable only in polytomous form is large, obtaining the maximum likelihood estimates is computationally rather labor expensive. Therefore, a more efficient method, the partition maximum likelihood method, is proposed. These estimation methods are demonstrated by real and simulated data, and are compared by means of a simulation study.     

Construct validity of four basic Vocational Interest factors

To find evidence of the generalizability of four interest factors established for tests within the Roe-Holland framework, factor scores derived from a Vocational Interest Inventory grounded in Roe's system were correlated with the empirically based Strong-Campbell Occupational scale scores. For this sample of 300 counseling clients, a majority of the hypothesized relations were found, and arranging the occupations along these bipolar dimensions both sharpened the definitions of the factors and provided an additional interpretive aid for counseling.     

Visioning Family-Centered Care in Genetics: What Parents and Providers Have to Say

The purpose of this multisite exploratory research study involving focus groups of consumers and service providers was to generate stakeholder input for a statewide strategic plan for genetic services in the southwestern region of the United States. This article describes the qualitative methods by which the data were collected and summarizes major themes in participants’ perceptions about genetic services. It also describes processes related to obtaining genetic services and characteristics of an ideal service delivery system for children affected by genetic disorders and the families that care for them. Implications for practice and policy are also reviewed.     

Yoga and the battlefield of ethics: Highlighting an infusion model for ethics education

This paper articulates an infusion model of ethics education for engineering students by illuminating the value of a religious studies course on yoga. This model is distinguished from four other possible approaches that have traditionally been used to prepare engineering students to face the challenges of the work place. The article is not claiming that this approach should be used to the exclusion of the other approaches, but rather that it adds strength to the other approaches. Specifically, the article claims that the infusion model provides an opportunity for students to reflect upon the foundational ethical positions emanating from the world's religions and thereby provides them with a vista from which they can not only ask what professional ethical code applies in a given situation, but also ponder the nature of character needed to follow that ethical code.
