TELEOLOGY IN BIOLOGY: WHO COULD ASK FOR ANYTHING MORE?

Abstract. Teleological thinking permeates biology and is useful in pondering unanswered biological questions. Such thinking differs from the usual sense of teleology in that “purpose” in biology carries no imputation of causation. A few examples are given. The teleological system of biology is every bit as elegant a construct of the human mind as any other teleological system and in no way precludes spirituality. I argue that it provides a firmer foundation for moral guidance than supernatural systems.     

Negative intergroup contact makes group memberships salient: explaining why intergroup conflict endures

Drawing from the intergroup contact model and self-categorization theory, the authors advanced the novel hypothesis of a valence-salience effect, whereby negative contact causes higher category salience than positive contact. As predicted, in a laboratory experiment of interethnic contact, White Australians (N = 49) made more frequent and earlier reference to ethnicity when describing their ethnic contact partner if she had displayed negative (vs. positive, neutral) nonverbal behavior. In a two-wave experimental study of retrieved intergenerational contact, American young adults (N = 240) reported age to be more salient during negative (vs. positive) contact and negative contact predicted increased episodic and chronic category salience over time. Some evidence for the reverse salience-valence effect was also found. Because category salience facilitates contact generalization, these results suggest that intergroup contact is potentially biased toward worsening intergroup relations; further implications for theory and policy making are discussed.     

Does adolescent heavier alcohol use predict young adult aggression and delinquency? Parallel analyses from four Australasian cohort studies

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.     

Taboo Trade-offs: Reactions to Transactions That Transgress the Spheres of Justice

Taboo trade-offs violate deeply held normative intuitions about the integrity, even sanctity, of certain relationships and the moral-political values underlying those relationships. For instance, if asked to estimate the monetary worth of one's children, of one's loyalty to one's country, or of acts of friendship, people find the questions more than merely confusing or cognitively intractable: they find such questions themselves morally offensive. This article draws on Fiske's relational theory and Tetlock's value pluralism model: (a) to identify the conditions under which people are likely to treat trade-offs as taboo; (b) to describe how people collectively deal with trade-offs that become problematic; (c) to specify the conceptual components of moral outrage and the factors that affect the intensity of reactions to various explicit trade-offs; (d) to explore the various strategies that decision-makers—required by resource scarcity and institutional roles to confront taboo trade-offs—use to deflect the wrath of censorious observers; (e) to offer a method of dispute resolution based on pluralism.     

Unconfigured Tractarian Objects

According to the Tractatus , the world consists of atomic objects arranged in various configurations, and the ways the world might be are determined by the ways these objects can be configured. The question I address is whether these very objects can be unconfigured as well as configured. Much depends on a positive answer to this question, including, as I show, the internal coherence of the Tractatus itself. I argue that these objects can be unconfigured, and am critical of certain interpretive claims made by Fogelin which lead to the conclusion that they cannot be.     

ATTITUDES TOWARD WOMEN IN TAIWAN AND CHINA

The goals of this article are to review published data from both English and Chinese sources on current attitudes toward women in Taiwan and China and to discuss issues in cross-cultural research that may affect the discovery and reporting of effects. Chinese women in both countries, when compared to men, had more liberal attitudes toward women, but women in China had more traditionally oriented attitudes than women in Taiwan. Yang's (1986) modernization theory was used to explain these results. There was also some overlap of gender roles in both cultures, with some traditional masculine (or feminine) roles played by the other gender. We propose that modernization may lead not only to greater gender equality but also to changes in the nature of gender roles, leading to greater gender-role overlap, in which it is advantageous for both men and women to have less distinctive gender-role characteristics. Finally, issues of construct validation, response sets, and alternative approaches to scale development are addressed, and suggestions for future research are offered.
