SummaryA total of 249 children and 805 adults living in the Asai valley of the New Guinea highlands was examined and measured for height, weight, sitting height and skinfold thickness. Mean ages for groups of children were calculated from regression equations of height on age for different dental stages.The growth of the Asai child in all measured parameters is slower than that reported from any other world situation. The relationship between the growth of the Asai child and adult size confirms (...) the finding, previously reported for New Guinean populations, that adult stature in a traditional society is proportionally related to, and possibly determined by, the growth rate of children in that society.Adult stature, which is at the lower end of the range for New Guinean populations, falls slightly with age, due to a decrease in trunk length. Weights and skinfold thickness, in common with other New Guinean populations, show a progressive fall with age.The role of malnutrition in the slow growth pattern is discussed and evidence is presented from New Guinean and other studies to support the hypothesis that natural selection for slow growth and shorter adult height occurs in conditions of nutritional deprivation.

This study examines Australian tax agents' perceptions of the ethical environment in which they practice, within the context of an income tax system based on self-assessment principles. The research identifies and ranks an inventory of ethical issues in terms of perceived frequency of occurrence and importance to Western Australian tax agents. In addition, the extent and influence of ethical concerns in the profession are evaluated.The study has determined that the most frequently cited ethical issue is the failure to make reasonable (...) enquiries where information or documentation provided by a client appears to be inaccurate or incomplete. The most important ethical problem is a failure to ensure confidentiality with regard to privileged client information. When the frequency of occurrence and importance means are compared, inadequate technical competence, failure to make reasonable enquiries/conduct research, continuing to act for a client where there is incorrect information, and conflicts in distinguishing between tax planning and tax avoidance emerge as the high frequency/high importance issues. Although acknowledging the potential for unethical actions in tax practice, Western Australian tax agents consider that they carry out their professional activities within an ethical environment.

The essays in this volume were written to celebrate the sixtieth birthday of G. E. L. Owen, who by his essays and seminars on ancient Greek philosophy has made a contribution to its study that is second to none. The authors, from both sides of the Atlantic, include not only scholars whose main research interests lie in Greek philosophy, but others best known for their work in general philosophy. All are pupils or younger colleagues of Professor Owen who are indebted (...) to his practice of philosophical scholarship as a first-order philosophical activity. At the heart of G. E. L. Owen's work has been a preoccupation with the role of philosophical reflection on language in the metaphysics and epistemology of Plato, Aristotle and other ancient Greek thinkers. This is accordingly the general topic of the present volume, which includes five papers on Plato's critical dialogues and seven on Aristotle, prefaced by two on Heraclitus and followed by a study of the debate in Hellenistic philosophy on the sorites. This is a book for specialists in Greek philosophy and philosophers of language which will also be of interest to some linguists. (shrink)

The human sentence processor is able to make rapid predictions about upcoming linguistic input. For example, upon hearing the verb eat, anticipatory eye-movements are launched toward edible objects in a visual scene. However, the cognitive mechanisms that underlie anticipation remain to be elucidated in ecologically valid contexts. Previous research has, in fact, mainly used clip-art scenes and object arrays, raising the possibility that anticipatory eye-movements are limited to displays containing a small number of objects in a visually impoverished context. In (...) Experiment 1, we confirm that anticipation effects occur in real-world scenes and investigate the mechanisms that underlie such anticipation. In particular, we demonstrate that real-world scenes provide contextual information that anticipation can draw on: When the target object is not present in the scene, participants infer and fixate regions that are contextually appropriate. Experiment 2 investigates whether such contextual inference requires the co-presence of the scene, or whether memory representations can be utilized instead. The same real-world scenes as in Experiment 1 are presented to participants, but the scene disappears before the sentence is heard. We find that anticipation occurs even when the screen is blank, including when contextual inference is required. We conclude that anticipatory language processing is able to draw upon global scene representations to make contextual inferences. These findings are compatible with theories assuming contextual guidance, but posit a challenge for theories assuming object-based visual indices. (shrink)

Academic dishonesty, including cheating and plagiarism, is on the rise in colleges, particularly among engineering students. While students decide to engage in these behaviors for many different reasons, academic integrity training can help improve their understanding of ethical decision making. The two studies outlined in this paper assess the effectiveness of an online module in increasing academic integrity among first semester engineering students. Study 1 tested the effectiveness of an academic honesty tutorial by using a between groups design with a (...) Time 1- and Time 2-test. An academic honesty quiz assessed participants’ knowledge at both time points. Study 2, which incorporated an improved version of the module and quiz, utilized a between groups design with three assessment time points. The additional Time 3-test allowed researchers to test for retention of information. Results were analyzed using ANCOVA and t tests. In Study 1, the experimental group exhibited significant improvement on the plagiarism items, but not the total score. However, at Time 2 there was no significant difference between groups after controlling for Time 1 scores. In Study 2, between- and within-group analyses suggest there was a significant improvement in total scores, but not plagiarism scores, after exposure to the tutorial. Overall, the academic integrity module impacted participants as evidenced by changes in total score and on specific plagiarism items. Although future implementation of the tutorial and quiz would benefit from modifications to reduce ceiling effects and improve assessment of knowledge, the results suggest such tutorial may be one valuable element in a systems approach to improving the academic integrity of engineering students.
