Analyzing Argumentative Discourse from a Rhetorical Perspective: Defining `Person' and `Human Life' in Constitutional Disputes Over Abortion

In this paper, a case study is presented of constitutional debates about abortion. An analysis is given of arguments from the Roe v. Wade case for definitions concerning the key notions of `person' and `human life'. The paper illustrates how the Court has gradually taken a more pragmatic or rhetorical position on definitional matters crucial to the purpose of regulating abortion.     

马王堆帛书《系辞》研究

本文主要研究马王堆帛书《系辞》中几处重要的异文。今本《系辞》中的“象”,帛书作“马”。“马”义同于“数”。《庄子》中说“天地一指也．万物一马也。”此处的“马”。与帛书《系辞》中的“马”同义。今本《系辞》中的“太极”,帛书作“大恒”。恒、常同义,《仪礼》中说“假尔大筮有常。”这个“常”即帛书《系辞》中的“大恒”。亦即《吕氏春秋·大乐》中的“天常”。今本《系辞》云“显诸仁,藏诸用”,帛书作“圣者仁,壮者勇”。儒家学说重视“勇”,《论语·宪问》即有云“仁者必有勇。”帛书《系辞》云“天地之大思日生。”“思”读为“司”,今本作“天地之大德日生。”帛书《系辞》又云“夫易古物定命”,其义同于“乾知大始,坤作成物”。今本《系辞》云“圣人以此洗心”．帛书作“圣人以此佚心”,佚、乐同义,马王堆帛书《五行》云“不安则不乐。不乐则无德。”     

Alternate methods and software for calculating interobserver agreement for continuous observation data

Portable electronic data collection devices permit investigators to collect large amounts of observational data in a form ready for computer analysis. These devices are particularly efficient for gathering continuous data on multiple behavior categories. We expect that the increasing availability of these devices will lead to greater use of continuous data collection methods in observational research. This paper addresses the difficulties encountered when calculating traditional interobserver agreement statistics for continuous, multiple-code scoring. Two alternative strategies are described that yield interobserver agreement values based on the exact time of behavior code entries by the primary and secondary observers.Work on this paper was supported in part by NICHD Grants P01HD15051 and R01HD17650 and Office of Special Education and Rehabilitation Services Grant G008302980.     

Medicine as a career: Choices and consequences

Medicine has traditionally been regarded as a rewarding career both financially and socially. How true, however, is that tradition in today's world of rising costs and decreasing revenues? The educational debt of the physician-in-training is steadily increasing, and currently does not affect specialty choice. As the cost of medical education continues to rise, the applicant pool begins to shrink, thereby possibly affecting the quality of future physicians. Once the physician has completed training however, the majority enjoy a positive return on investment. Their incomes generally fail to remain ahead of inflation, and therefore, have remained within a narrow band of $40,000 in 1970 dollars. Finally, the demand for physician services cannot be attributed solely to either the consumer (patient) or to the supplier (physician). Rather, the demand for medical services appears to be a unique combination of the two. In conclusion, medicine still is an attractive career path, but the choices and consequences are becoming much more demanding.     

Burhoe's Second-Hand Influence

Many of us not part of the "old Burhoe gang" are nonetheless deeply influenced by the ideas of Ralph Wendell Burhoe, albeit in indirect ways. This remembrance summarizes six such ways: Three are "procedural" influences, namely (1) that dialogue is most valuable, especially in the science/religion interface, when carried on among those who may not agree; (2) that scholarship is necessary to refine and improve preliminary opinions; and (3) that organizations are crucial to accomplishing the first two tasks. The three "substantive" influences are (4) Burhoe's focus on human values; (5) his work in defining God; and (6) his contribution to defining what it means to be human. As is well known, his emphasis in all three substantive cases was on the power and nuances of biological and social evolution, especially on the dynamics of natural selection.     

THE EFFECTS OF CONTINGENT AND NONCONTINGENT REWARDS ON THE I.Q. SCORES OF CHILDREN OF ABOVE-AVERAGE INTELLIGENCE1

This study investigated the effects of candy reinforcement on I.Q. test scores in first and second graders of above-average intelligence. Thirty-six subjects were randomly assigned to one of three groups and either given candy contingent on correct responses, noncontingently, or not given candy. After measuring all subjects on Form L of the revised Stanford Binet, each subject in the contingent group was given an M & M immediately following each correct answer on Form M, while a yoked-comparison subject received the same number of M & M's before responding to a question and therefore without regard to correctness of answers. It was expected that both types of candy administration would produce higher I.Q. change scores than the no-candy control group, but there were no statistically significant differences among the three treatments. The differences between the first and second test scores were 4.17 (contingent), 4.67 (noncontingent), and 1.00 (no reinforcement). Reasons for this failure to replicate previous findings were discussed.     

A comprehensive dining program for mentally retarded adults

Twenty-six types of behavior (e.g. uses fork in socially appropriate manner, chews food before swallowing) were treated in a course of independence training, using 80 institutionalized retarded adults (40 experimentals and 40 no-treatment controls). The 3-month long training phase incorporated a number of treatment components including in vivo modeling, peer social reinforcement, self-evaluation and monitoring; then a four-month follow-up. A group (i.e. experimentals and controls) by sex, by time, analysis of variance was computed with repeated measures on the last dimension (pre, post, follow-up measures = time). A significant difference was obtained between the experimentals and controls on post-test and follow-up     

PILLS OR SKILLS FOR HYPERACTIVE CHILDREN

The controversial nature of drug treatment of hyperactivity, the incidence and sequelae of hyperactivity, and problems of differential diagnosis of hyperactivity versus aggression were discussed. The effects of psychostimulant medication and behavior therapy on hyperactive children were reviewed with regard to effects on their social and academic behavior. Both treatments have resulted in clear short-term changes in social behavior but neither long-term academic nor long-term social effects have been shown with either treatment. Short-term effects on academic behavior have resulted from behavioral interventions but not from psychostimulants. However, the interventions have been too brief to allow one to draw unequivocal conclusions about the clinical efficacy of behavioral treatments. Although there have been long-term evaluations of psychostimulant therapy, there have not been any evaluations of long-term behavioral treatment programs for hyperactive children. Given the salutary short-term effects of behavior therapy with hyperactive children, extended clinical trials of behavior therapy need to be conducted. Finally, specific directions are suggested for future research.     

Simplifying continuous monitoring of multiple-response/multiple-subject classroom interactions

In order to facilitate the field monitoring of three subjects interacting according to one or more of 18 response categories, a modified version of several available, but oftentimes mechanically incompatible, observational procedures was designed. Its continuous recording strategy, sectioned into one-minute observational units, enabled researchers to derive highly representative behavior samples, and when accompanied by the specially tailored coding form and recording apparatus, observers achieved over 90% agreement across all reliability sessions. This procedure provides applied researchers with a simple, highly reliable, and adaptable observation tool for continuously and simultaneously monitoring the behaviors of one or more subjects.     

The effect of witnessing consequences on the behavioral recordings of experimental observers

The cueing effects of interviewer praise contingent on a target behavior and expectation of behavior change were examined with six observers. Experiment I investigated the effect of cues in conjunction with expectation. Experiment II assessed the relative contributions of cues and expectation, and Experiment III examined the effect of cues in the absence of expectation. The frequencies of two behaviors, client eye contact and face touching, were held constant throughout a series of videotaped interviews between an "interviewer" and a "client". A within-subjects design was used in each experiment. During baseline conditions, praise did not follow eye contact by the client on the videotape. In all experimental conditions, praise statements from the interviewer followed each occurrence of eye contact with an equal number of praises delivered at random times when there was no eye contact. Three of the six observers dramatically increased their recordings of eye contact during the first experimental phase, but these increases were not replicated in a second praise condition. There were no systematic changes in recorded face touching. Witnessing the delivery of consequences, rather than expectation seemed to be responsible for the effect. This potential threat to the internal validity of studies using observational data may go undetected by interobserver agreement checks.
