Environmental factors influencing the affiliative behavior of male and female rats (Rattus norvegicus)

Three experiments were conducted to investigate the influence of rearing and housing manipulations on the affiliative behavior of male and female rats. Animals were tested in same-sex pairs in an open field for time spent in contact and for socially facilitated activity. The results revealed a sex difference in both the degree and the form of affiliative behavior of rats. In general, males were more affiliative and more responsive to a second animal. Males engaged in more rough-and-tumble play, whereas females spent more time in social grooming. Housing conditions of adult animals and rearing conditions were found to influence the degree to which males engaged in male-like affiliative behaviors and females engaged in female-like affiliative behaviors. Social behavior appears to be a function of the interaction between the affiliative repertoire of the animals involved, the nature of the social stimulus, and the features of the environment.     

An Intelligent Marking Assistant: An Application of Artificial Intelligence in Teaching

We are entering the second computer revolution — described by many as “THE REVOLUTION”. The Japanese have committed themselves to a programme to develop a Fifth Generation of computers — machines that can understand natural language, diagnose problems, and discover solutions. What are the implications for higher education?

This paper argues that the most interesting applications of this new technology are in producing “intelligent assistants” or “powerful tools” in the teaching/learning process. It describes in some detail a particular “Expert System” being used in this role — assisting academic staff with the evaluation of student work.     

Is there a future for school counseling in the United States?

School counseling in the United States is going through a very difficult period. Reasons for the difficulties are discussed. Suggestions are offered for modifications in counseling practice and in counselor education needed to overcome the current problems. Hopefully, the issues raised in the paper will be especially relevant in those countries which have relied heavily on literature and expertise from the United States in developing their counseling services.     

Risk acceptability and cost-effectiveness of protective measures against terrorist threats to built infrastructure considering multiple threat scenarios

Decisions are often needed about the need and/or extent of protective measures against explosive blast loads on built infrastructure. A decision support analysis considers fatality risks and cost-effectiveness of protective measures expressed in terms of expected cost spent on risk reduction per life saved for terrorist threats to infrastructure. The analysis is applicable to any item of infrastructure, but in this paper is applied to casualties arising from building facade glazing damage. Risks may be compared with risk acceptance criteria in the form of quantitative safety goals. The risk acceptability and cost-effectiveness of protective measures includes cost of the protective measures, attack probability,reduction in risk due to protective measures,probability of fatality conditional on successful terrorist attack and number of exposed individuals.     

An evaluation of argument mapping as a method of enhancing critical thinking performance in e-learning environments

The current research examined the effects of a critical thinking (CT) e-learning course taught through argument mapping (AM) on measures of CT ability. Seventy-four undergraduate psychology students were allocated to either an AM-infused CT e-learning course or a no instruction control group and were tested both before and after an 8-week intervention period on CT ability using the Halpern Critical Thinking Assessment. Results revealed that participation in the AM-infused CT course significantly enhanced overall CT ability and all CT sub-scale abilities from pre- to post-testing and that post-test performance was positively correlated with motivation towards learning and dispositional need for cognition. In addition, AM-infused CT course participants exhibited a significantly larger gain in both overall CT and in argument analysis (a CT subscale) than controls. There were no effects of training on either motivation for learning or need for cognition. However, both the latter variables were correlated with CT ability at post-testing. Results are discussed in light of research and theory on the best practices of providing CT instruction through argument mapping and e-learning environments.     

Attitudes of Australian chiropractic students toward whole body donation: A cross‐sectional study

Cadavers play an important role in anatomy education. In Australia, bodies for anatomy education are acquired only through donations. To gain insight into educational dynamics in an anatomy laboratory as well as to facilitate body donation programs and thanksgiving ceremonies, it is important to understand students' attitudes toward body donation. In this cross‐sectional study, the attitudes of Macquarie University's first, second, and fifth year chiropractic students toward body donation were investigated. Macquarie University chiropractic students have a four semester long anatomy program, which includes cadaver‐based instruction on prosected specimens. A questionnaire was used to record respondents' demographics and attitudes toward body donation: personal, by a relative, and by a stranger. It was found that ethnicity and religion affect attitudes toward body donation, with Australian students being more willing to donate a stranger's body and atheists and agnostics being more willing to donate in general. Furthermore, willingness to donate one's own or a family member's body decreases as year of study increases, suggesting a possible negative impact of exposure to cadavers in the anatomy laboratory. This was only true, however, after controlling for age. Thus, the impact of viewing and handling prosected specimens, which is the norm in anatomy classes in Australia, may not be as strong as dissecting cadavers. It is suggested that anatomists and educators prepare students for cadaver‐based instruction as well as exhibit sensitivity to cultural differences in how students approach working with cadavers, when informing different communities about body donation programs and in devising thanksgiving ceremonies.
