Ethics education in science and engineering: The case of animal research

Conclusion The past one hundred fifty years of debate over the use of animals in research and testing has been characterized mainly byad hominem attacks and on uncritical rejection of the other sides’ arguments. In the classroom, it is important to avoid repeating exercises in public relations and to demand sound scholarship. This paper is a modification of material originally included in the handbook which accompanied the American Association for the Advancement of Science (AAAS) Seminar “Teaching Ethics in Science and Engineering”, 10–11 February 1993.     

Guidelines for training in the ethical conduct of scientific research

Historically, scientists in training have learned the rules of ethical conduct by the example of their advisors and other senior scientists and by practice. This paper is intended to serve as a guide for the beginning scientist to some fundamental principles of scientific research ethics. The paper focuses less on issues of outright dishonesty or fraud, and more on the positive aspects of ethical scientific behavior; in other words, what a scientist should do to maintain a high level of ethical conduct in research. There are a number of fairly specific rules, guidelines, or commonly accepted operating principles that have evolved for the ethical conduct of science. In order to discuss this code of ethics, this paper is divided into sections dealing with specific areas of scientific ethics. These areas are: data collection and storage, ownership of data, confidentiality, communication, authorship, collaboration, the peer review system, and rules of dealing with ethical complaints. Illustrative case histories are presented to provide examples of the type of ethical dispute or problem being discussed. If scientific trainees learn the accepted rules of behavior that govern the conduct of science, ethical problems that arise out of ignorance, misunderstanding, or poor communication can be avoided.     

Within-category discrimination of musical chords: Perceptual magnet or anchor?

Recent speech research has begun to evaluate the internal structure of categories. In one such study, Kuhl (1991) found that discrimination was poorer for vowel stimuli that were more representative of the category (prototype, or P, set) than it was for less representative stimuli (nonprototype, or NP, set). This finding was interpreted as indicating that a category prototype may function as a “perceptual magnet,” effectively decreasing perceptual distance, and thus discriminability, between stimuli. The present study examines the function of prototypes in a musical category—another natural, but nonspeech category. Paralleling the Kuhl study, representative (P) and less representative (NP) sets of major triad stimuli were constructed, based on equal temperament. Musically experienced subjects rated the stimuli in each set for goodness as a major triad, with the highest rated stimulus serving as a prototype standard for a subsequent discrimination task. Results from the discrimination task demonstrated better performance in the P context than in the NP context. The current nonspeech results indicate that a prototype functions as an anchor rather than a magnet. In addition to providing a natural, nonspeech standard for comparison with speech findings, the results provide some important insights into the nature of musical categories.

The comorbidities of adolescent problem behaviors: A latent class model

The correlations and comorbidities of a series of adolescent problem behaviors were studied in a sample of 739 New Zealand 15-year-olds. This analysis revealed the presence of strong comorbidities between different problem behaviors. The data were modeled using methods of unrestricted latent class analysis and this suggested that the best fitting model to describe the data was one which assumed that adolescent problem behaviors were described by four general classes of children. While the same general four-class model applied to males and females, there were marked gender differences in the rates of problems. Specifically, the predominant problem behaviors in females were those relating to an accelerated transition to adulthood marked by early sexual activity, alcohol abuse, and cannabis use whereas the predominant problems for boys were related to antisocial and law-breaking behaviors. Rates of children with no problems (85%) and with multiple problems (3%) were similar for boys and girls.This research was funded by grants from the Health Research Council of New Zealand, the Canterbury Medical Research Foundation, and the National Child Health Research Foundation.     

Gender-related assessment of childhood play

Parent-report based scales for the assessment of sex-dimorphic behavior are an important tool in research on psychosexual differentiation and its disorders. This paper presents the factor analysis and corresponding scale development for the slightly expanded Child Game Participation Questionnaire (Bates & Bentler, 1973), based on the parents of a demographically diverse school sample of 355 girls and 333 boys aged 6 to 10 years. Evidence supporting each of three theoretical positions in gender assessment — unidimensional bipolar, two-dimensional unipolar, and multidimensional — was provided. Effect sizes were unusually large for gender, but small for age, socioeconomic level, and race/ethnicity.This research was supported in part by a NICHD postdoctoral fellowship (NRSA HD06726; sponsor: Dr. Meyer-Bahlburg) awarded to Dr. Sandberg, by grants to Dr. Ehrhardt and Dr. Meyer-Bahlburg from the Spencer Foundation, the William T. Grant Foundation, the Ford Foundation, and NIMH (center grant 2-P50-MH43520, Anke A. Ehrhardt, Ph.D., Principal Investigator), and by the NIMH Clinical Research Center grant MH-30906.We thank the children and parents who participated in the study. Dr. Jacob Cohen consulted on statistical matters. Ms. Patricia Connolly provided word processing services. A portion of this work was presented as a poster at the XIth Biennial Meeting of the International Society for the Study of Behavioral Development, Minneapolis, Minnesota, July 3–7, 1991 (Abstracts, p. 285).     

Enhancing possible selves in Mexican American students

This project assessed the modifiability of possible selves in young Mexican American children. Three intervention conditions were compared in a pre- and posttest design: child-only intervention, parent and child intervention, and a no-intervention control. Following eight intervention sessions, children in the two intervention groups showed significant gains in understanding the characteristics associated with becoming a good student and in recognizing the value of education in bringing about future occupational goals. Children in the intervention conditions also reported greater interest in becoming a physician, judge, or pilot — occupations they had directly experienced during training. The parent intervention phase contributed little to augmenting the positive results attributable to the child intervention component.This research was conducted under the auspices of NIH Grant HD-24003. We wish to thank Maritza Robles and the staff of the Bilingual program of the South Bend, IN, Corporation for their support.     

The new qualification in careers guidance in higher education: A collaborative partnership

The raison d'être for the new Certificate and Diploma in Careers Guidance in Higher Education is outlined. The different perspectives of the partners in this enterprise–the Department of Community Studies at the University of Reading and the Association of Graduate Careers Advisory Services (AGCAS)–are discussed. The initial difficulties and successes are explored and a suggested strategy is offered for other such collaborative ventures.     

Gender identity and bulimic eating behavior

From a social-psychological perspective, the disproportionate number of women compared to men affected by bulimia nervosa implies that gender (i.e., the social construction of sex) plays an important part in the etiology of this disorder. From this perspective it was hypothesized that the risk of developing bulimia depends, in part, on the composition of a woman's gender identity. Three questionnaire studies conducted in the United States and former West Germany tested competing hypotheses on the relationship between gender identity and bulimia. Respondents were predominantly middle class and Caucasian. Study 1 was conducted in West Germany and tested the hypothesis that bulimia is related to a hyperfeminine gender identity [M. Boskind-Lodahl (1976) Cinderella's stepsisters: A feminist perspective on anorexia nervosa and bulimia, Signs, Vol. 2, pp. 342–356]. Twenty-six bulimic women were compared to 26 nonbulimic women. Results from Study 1 indicated that bulimic women typically had a gender-typed identity, whereas nonbulimic controls tended to be androgynous. However, between-group differences were based on hypomasculinity rather than hyperfemininity on part of bulimic women. Study 2 and Study 3 explored the idea that masculinity positively contributes to general esteem and reduces the risk of bulimia nervosa. In Study 2, three competing theories of the optimal relationship between mental health and gender identity (congruence, androgyny, and masculinity) were related to bulimia and tested with structural equation modeling in a sample of 301 North American undergraduates. In Study 3, the findings of Study 2 were cross-validated in a sample of 464 West German high school students. The results indicate that masculinity had significant positive effects on eating behavior via esteem, whereas the effects of femininity were negligible.The research and preparation of this article were supported in part by a Fulbright scholarship, a predoctoral stipend from the University of Heidelberg, and a postdoctoral stipend from the Max Planck Institute for Human Development and Education.I thank the women who volunteered to participate in this research project as subjects.
