A total of 1918 loci, detected by the hybridization of 938 expressed sequence tag unigenes from 26 Triticeae cDNA libraries, were mapped to wheat homoeologous group 4 chromosomes using a set of deletion, ditelosomic, and nulli-tetrasomic lines. The 1918 EST loci were not distributed uniformly among the three group 4 chromosomes; 41, 28, and 31% mapped to chromosomes 4A, 4B, and 4D, respectively. This pattern is in contrast to the cumulative results of EST mapping in all homoeologous groups, as reported (...) elsewhere, that found the highest proportion of loci mapped to the B genome. Sixty-five percent of these 1918 loci mapped to the long arms of homoeologous group 4 chromosomes, while 35% mapped to the short arms. The distal regions of chromosome arms showed higher numbers of loci than the proximal regions, with the exception of 4DL. This study confirmed the complex structure of chromosome 4A that contains two reciprocal translocations and two inversions, previously identified. An additional inversion in the centromeric region of 4A was revealed. A consensus map for homoeologous group 4 was developed from 119 ESTs unique to group 4. Forty-nine percent of these ESTs were found to be homoologous to sequences on rice chromosome 3, 12% had matches with sequences on other rice chromosomes, and 39% had no matches with rice sequences at all. Limited homology was found between wheat ESTs on homoeologous group 4 and the Arabidopsis genome. Forty-two percent of the homoeologous group 4 ESTs could be classified into functional categories on the basis of blastX searches against all protein databases. (shrink)

The book provides a practical guide to the application of Critical Realism (CR), an increasingly popular philosophy of social science, in empirical research projects. Each purpose-written chapter reviews major social science research methods and contains extended illustration of how to conduct inquiry using CR.

Using multi–sources: archeaology, history, geography, anthropology, wildlife, zoology, biology, oral tradition and archival material, the article examines the history of the elephant in Ghana, highlighting the various methods employed in hunting as well as the cultural and economic use values of the elephant in Ghana.

The transition from the Athenian Peripatos of Aristotle to the Alexandrian Museion of Callimachus has often attracted notice. So closely akin was the organization of scholarship in the two centres of learning, so definite was the personal connexion between the two, that it seemed possible to trace an uninterrupted line of succession from the older to the younger school. That Callimachus the scholar worked in the Aristotelian tradition appeared obvious: ‘he might be called a Peripatetic in the same sense as (...) his pupils, but with more justification’ (Wilamowitz,Hellenist. Dicht.i. 214). Regarding Callimachus the poet and literary critic the picture seemed less clear. The non-classical character of his poetry had often been emphasized, and cannot be overlooked. But quite recently an attempt has been made to turn Callimachus into an Aristotelian even by virtue of his literary criticism. The alleged harmony of this development rouses suspicion and calls for inquiry. In the following pages I have tried to collect and discuss what material I could find for the relation of Callimachus to Aristotle and his school. I hope to show that such influences as there were are of a different and more subtle nature, and that this poet, if any, was his own Longinus. (shrink)

In the present paper two kinds of quantum-theoretical states are considered: the “physical state” determined by a complete observation and the “intrinsic state” which comprises the values of the observed as well as the unobserved observables. It will be shown that the future values of all these observables are determined. Causality is therefore valid, though not verifiable.

We examine the interface of entrepreneurship and society by considering a novel source of gender bias (public opinion) and a novel expression of it (affective evaluations). We posit that women-led teams displaying success will trigger a “penalty for success” bias, and this will be inhibited if the team receives a “stamp of approval” from a gender congruent individual (i.e., an investor who is a man). Analysis from our first study, based on archival data, indicated that other mechanisms might be at (...) play that we could not tease apart in our archival data, so we conducted a follow-up experimental study to further examine our initial findings. Results jointly indicate that women are viewed unfavorably unless either (a) they are validated by success or endorsement from a man, or (b) they fail but are “warm and accommodating” about it. We also find that while men benefit from being validated by success or endorsement of an opposite-gender investor, they do not face a similarly steep penalty absent that validation. (shrink)

James questions the validity of the very tentative statement made in the final sentence of our paper. Our claim concerned the proportion of twins in Britain in the 1990s that might have arisen through subfertility treatment and was linked to the suggestion that the natural twinning rate might still be in decline. If this were true, we, like James, would regard that prospect with concern.

We argue that developing a human ethics application is an effective method for refining the intent and design of research studies. Our study aimed to investigate the delivery of end-of-life and palliative care nursing to residents of an aged care unit in a Multi-purpose Service/centre in rural Victoria. We used the ethics application process as a strategy to focus the study, and to refine the data collection and analysis techniques. It is our contention that the process of completing the application (...) and gaining ethics approval is laborious; however, the intellectualising that occurs provides researchers with an opportunity to reflect upon and refine their studies, thus ensuring the ultimate success and timely completion of research investigations.

We investigate what it means for a (Hausdorff, second-countable) topological group to be computable. We compare several potential definitions based on classical notions in the literature. We relate these notions with the well-established definitions of effective presentability for discrete and profinite groups, and compare our results with similar results in computable topology.
