Acceptance of Evolution and Support for Teaching Creationism in Public Schools: The Conditional Impact of Educational Attainment

Public acceptance of evolution remains low in the United States relative to other Western countries. Although advocates for the scientific community often highlight the need for improved education to change public opinion, analyses of data from a national sample of American adults indicate that the effects of educational attainment on attitudes toward evolution and creationism are uneven and contingent upon religious identity. Consequently, higher education will only shift public attitudes toward evolution and away from support for teaching creationism in public schools for those who take non‐“literalist” interpretive stances on the Bible, or to the extent that it leads to fewer people with literalist religious identities.     

Evolution of communication in perfect and imperfect worlds

We extend previous work on cooperation to some related questions regarding the evolution of simple forms of communication. The evolution of cooperation within the iterated Prisoner's Dilemma has been shown to follow different patterns, with significantly different outcomes, depending on whether the features of the model are classically perfect or stochastically imperfect (Axelrod, 1980a,b, 1984, 1985; Axelrod and Hamilton, 1981; Nowak and Sigmund, 1990, 1992; Sigmund, 1993). Our results here show that the same holds for communication. Within a simple model, the evolution of communication seems to require a stochastically imperfect world.     

Why True Globalization Depends on New Scientific Models

Ervin Laszlo's Science and the Akashic Field is vital to our transition from a long epoch of empire building—of the drive to control Earth's resources by fierce competition in a situation of perceived scarcity—to a future of truly cooperative global family. Laszlo's universe is a far cry from the one Western science has taught us and compatible with my own views as a “post-Darwinian” evolution biologist. In fact, no small number of Western scientists today have defected from the official scientific story of How Things Are to create or adopt various versions of the new scientific worldview Laszlo presents—a worldview rooted in older sciences and cultures such as Vedic, yet ultimately not just timely, but futuristic. These new scientific models, integrating ancient and modern knowledge, represent a paradigm shift greater than the Copernican revolution and are crucial to the next stage in humanity's evolution as a planetary species.     

Vigilant Self‐regulation and Costly Punishment in Public Goods Situations

Applying regulatory focus theory to the context of social dilemma situations, the present research demonstrates that individual differences in vigilant, prevention‐focused self‐regulation predict the tendency to invest private resources to punish uncooperative interaction partners (costly punishment), a behaviour that typically has strong positive effects on the collective level of cooperation. Analyses further support the distinctiveness of the vigilance system proposed in regulatory focus theory (prevention focus) in comparison with general defensive inhibitory tendencies (measured with Carver and White's Behavioral Inhibition System scale). Results document that individual differences in prevention‐focused self‐regulation but not differences in general defensive inhibitory tendencies are positively related to costly punishment. In sum, the findings indicate that vigilant, prevention‐focused self‐regulation plays a crucial role in the context of sanctions that enforce cooperation.

Lashing Out after Stewing over Public Insults: The Effects of Public Provocation,Provocation Intensity,and Rumination on Triggered Displaced Aggression

Four studies present the first evidence showing that public (vs. private) provocation augments triggered displaced aggression by increasing the perceived intensity of the provocation. This effect is shown to be independent of face‐saving motivation. Following a public or private provocation, Study 1 participants were induced to ruminate or were distracted for 20 min. They then had an opportunity to aggress against another person who either acted in a neutral or mildly annoying fashion (viz. triggering event). As expected, the magnitude of the greater displaced aggression of those who ruminated before the triggering event compared with those distracted was greater under public than private provocation. Study 2 replicated the findings of Study 1 and confirmed that public provocations are experienced as more intense. Studies 3 and 4 both manipulated provocation intensity directly to show that it mediated the moderating effect of public/private provocation found in Study 1. The greater intensity of a public provocation increases reactivity to a subsequent trigger, which in turn, augments triggered displaced aggression. Aggr.

Shock tactics to counter AIDS: The australian experience

Abstract

The use of shock tactics to motivate people to learn more about AIDS and to take appropriate protective action characterised the approach adopted by the national health authorities in Australia during 1987. The rationale underlying this approach is critically examined, particularly in the light of results obtained from surveys of community concern and knowledge about AIDS in the state of South Australia before the campaign and after it had been in progress for some five months. Contrary to expectations no significant increases in either personal or social concern were found; in fact, among older respondents personal concern had decreased significantly. Levels of knowledge about AIDS, in general, remained unchanged, apart from an increase in acceptance of the safety of blood transfusions from a very low to a somewhat higher level. Among a minority of respondents (29%) who approved of the campaign and also believed they had been influenced by it, personal and social concern about AIDS, but not knowledge, was significantly greater than among others. The view that fear-inducing techniques can be used to bring about increases in knowledge about AIDS was not supported, although some positive effects on the social attitudes of respondents most affected by the campaign are suggested.     

Between Private and Public Sectors

This article validates Simon Kuznets’ argument that minorities prefer the private sector to the public sector in order to avoid discrimination. Based on new archival findings, comparative interethnic research shows that majority Greek civil engineers in the interwar years developed close, interlocking relations with the government and national institutions, which elevated their socio-professional status. Despite the absence of anti-Jewish legislation, this process effectively excluded equally qualified Jewish engineers from Greek-controlled power networks and employment. The Greek nationalistic climate of the times permeated the civil engineers’ professional associations and Greece's one higher educational institution (National Technical University of Athens) of engineering. As the professional networks consolidated to protect their interests, Jewish civil engineers and architects, employers and employees alike, were effectively shut out with no possibility of benefitting from professional integration or association with the mainstream community of civil engineers. Jewish civil engineers were, therefore, channelled into restricting their services to Jewish clients and community projects. However, with the newly developing large-scale armaments industries in the 1930s, Jews opted to train as chemical, mechanical, and electrical engineers to fill positions in family-owned firms (as did their fellow Greeks), and also found employment in lower paying jobs that Greek engineers considered unattractive in state-owned facilities.     

The Microcomputer as Perceptual Tool:

The microcomputer as a medium of instruction is not inherently better or worse than any other medium be it lecture, television, print or practical experience. However, the microcomputer can simultaneously present instruction and collect data on student performance. In order for educators to evaluate the success of instruction presented by computer they must use the microcomputer as a perceptual tool to more sensitively monitor and modify the educational process. Thoughtful consideration of monitoring data by special educators promises to make the microcomputer a revolutionary aspect of school instruction. Such an educational revolution can extend to the delivery of special services provided that the time and ancillary supports needed to utilize performance are made available to school personnel.     

A Self-Modeling Intervention for High School Students with Public Speaking Anxiety

ABSTRACT

The study investigated the effectiveness of self-modeling as an intervention for public speaking anxiety. The participants were six high school students with elevated levels of self-reported public speaking anxiety. Students presented public speeches to randomly selected peer audiences. Direct observations measured the behavioral manifestations of public speaking anxiety. In the intervention phase, students viewed self-modeling videotapes that were edited to remove speech dysfluencies and behavioral symptoms of speech anxiety. The self-modeling tapes depicted only adaptive, exemplary behavior with an edited-in audience feature making it appear that the students were producing a fluent speech to an audience of their peers. All of the participants evidenced substantial decreases in behavioral symptoms of speech anxiety and these changes were maintained throughout follow-up. The range of the participants' effect sizes was 2.7 to 4.9. Self-report measures of state anxiety and confidence as a speaker were used to assess additional effects of treatment. For all participants, there were also substantial decreases in self-reported public speaking anxiety and state anxiety from baseline to follow-up. A post-treatment interview revealed high social validity and self-reported generalization of treatment.
