The Heritability of Characteristics Associated with Dispositional Empathy

ABSTRACT This investigation used data from Loehlin and Nichols's (1976) study of over 800 sets of twins to examine evidence for the heritability of three facets of empathy: empathic concern, personal distress, and perspective taking. Expert judges first identified sets of adjectives, included within Loehlin and Nichols's original data, which reflected each empathy construct; these items were then validated in an independent sample. Comparisons of the responses given to these items by identical and fraternal twins in the Loehlin and Nichols investigation revealed evidence of significant heritability for characteristics associated with the two affective facets of empathy—empathic concern and personal distress—but not for the nonaffective construct of perspective taking. This pattern is consistent with the view that temperamental emotionality may underlie the heritability of affective empathy.     

African-American Women and the Male-Female Relationship Dilemma: A Counseling Perspective

This article focuses on the historical origin of the African-American male-female relationship dilemma and contemporary forces that have an impact on opportunities for intimacy and marriage among African-American women. Specifically, loss, communication, and stereotypes are examined as counseling issues that are relevant to African-American women in relationships. Implications for counseling and research are also discussed.     

The earth summit and the promotion of environmentally sound industrial innovation in developing countries

With the end of the cold war, issues of environment and economic development are assuming greater international salience. By the 1970s, environmental degradation was becoming pervasive, with growing global effects. Increasingly, global and emergent globalized problems are forcing environmental interdependence on the world. Transboundary threats cannot be addressed unilaterally by any single country or group of countries. The global environmental agenda is reviving the North-South debate and rejuvenating the Third World coalition in international fora. The encouragement of environmentally sustainable forms of industrialization in the South requires expanded and improved international cooperation. However, the North’s greater resources and greater responsibility in causing global environmental degradation require its continuing involvement in the search for solutions, including ones applicable to newly industrializing countries. In June 1992, the largest intergovernmental conference ever held was convened in Rio de Janeiro to address these issues: the United Nations Conference on Environment and Development (UNCED, or the Earth Summit). It produced a consensus action plan of about 700 pages: Agenda 21. Agenda 21 presents massive challenges for international cooperation as well as for national and private actors and scientific and technical institutions. It reflects a complex configuration of demands for institutional arrangements that support environmentally sustainable technical and socioeconomic change. One of the most consistent of the Agenda 21 themes, and one of the most intractable issues, concerns “access to technology.” This can be as straightforward as diagnosing and improving the efficiency of a production process in a small manufacturing firm, or as complex as engineering a technological revolution in which production and consumption take place with virtually no material or energy loss to the environment. The selection of entry points for action is a critical strategic problem as well as an important operational issue. In this paper I identify and describe new initiatives intended to improve the environmental performance of industry in the South, and find that they largely aim to promote incremental industrial innovation through international technology transfer and diffusion. This strategy raises many questions about how to promote effective technology transfer and diffusion. This is a revised version of a paper prepared for the ORSTOM/UNESCO Conference “20th Century Science: Beyond the Metropolis,” Paris, 19–23 Sept. 1994.     

Embryos created for research purposes.

The creation of embryos for research use has drawn a great deal of criticism. It is difficult to defend an ethical distinction between what one can do to "spare" embryos and what one can do to "research" embryos. The strongest ground on which to argue against the creation of embryos for research is a symbolic one, having to do with respect for human life. Ronald Dworkin's work in Life's Dominion on the symbolic meaning of the abortion debate throws a helpful light on this dispute. By understanding the basic question to be, Does the creation of research embryos weaken or insult our communal respect for the sanctity of human life in some way that in vitro fertilization (IVF) or the experimental use of "spare" embryos does not?, the debate can move in a more constructive direction.     

An historical preface to engineering ethics

This article attempts to distinguish between science and technology, on the one hand, and engineering, on the other, offering a brief introduction to engineering values and engineering ethics. The method is (roughly) a philosophical examination of history. Engineering turns out to be a relatively recent enterprise, barely three hundred years old, to have distinctive commitments both technical and moral, and to have changed a good deal both technically and morally during that period. What motivates the paper is the belief that a too-easy equation of engineering with technology tends to obscure the special contribution of engineers to technology and to their own professional standards and so, to obscure as well both the origin and content of engineering ethics.     

Sexual assault: Myths and stereotypes among Australian adolescents

Myths and stereotypes about sexual assault reflect a society which excuses perpetrators of assault and blames victims for failing to control men's sexuality. Such views are well-established by early adulthood, but there is little research with adolescents. This study surveyed two hundred forty-four 14–16 year old Australian high school students (105 male, 139 female), of Anglo-European descent. Males were significantly more likely to endorse sexual assault myths, to agree that forced sex was acceptable in some situations, and to hold false stereotypes about sexual assault. Males also held more restrictive attitudes toward women's roles and endorsed a greater level of sexism in dating relationships. This suggests that male and female adolescents have differing expectations of dating relationships, which may underlie sexual assault within relationships. Assault-supportive attitudes are apparent at a young age, supporting the need for educational and social interventions targeting young people.     

Emotional Self-Awareness,Eating Disorders,and Racial Identity Attitudes in African American Women

Certain racial identity attitudes may involve diminished internal emotional awareness, features of a syndrome known as “alexithymia,” which has been observed in survivors of extreme trauma. This study found that levels of alexithymia, but not eating disorders, were related to attitudes characteristic of early stages of racial identity development among African American women.     

Conditioned fear and startle magnitude: effects of different footshock or backshock intensities used in training

In Experiment 1 four groups of rats received 30 light-shock pairings using footshock intensities of either .2, .4, .8, or 1.6 mA. One day later all rats were tested for startle by presenting tones in the presence or absence of the light CS. Potentiated startle (the difference between startle on light-tone vs tone-alone trials) was nonmonotonically related to the shock intensity used in training, with the greatest potentiation at intermediate shock levels. Experiment 3 demonstrated a similar relationship when backshocks instead of footshocks were used. In Experiment 2 rats were trained with either a moderate or high shock and then given an extended extinction-test session 1 day later. The moderate-shock group showed a gradual decline in potentiated startle over extinction. The high-shock group showed a nonmonotonic extinction curve where potentiation progressively increased toward the middle of extinction and dissipated thereafter. The results suggest that acoustic startle bears an inverted U-shaped relationship to fear and are discussed in relation to other studies concerned with this issue.     

A method of restraining goldfish during conditioning of electric-shock-induced suppression of breathing movements

An efficient method of holding individual fish in position for delivery of visual conditioned stimuli and electrical unconditioned stimuli, and for registration of breathing movements with a thermistor, is described. The holder restrains the fish gently and is readily opened and closed. In addition, a “mechanical fish” signal generator, for assessing thermistor performance in detecting breathing movements, and a safe constant-current electrical shock stimulus generator are described.
