The impact of court delays on the prosecutor and the defendant: an economic analysis

One important aspect of the economic theory of criminal court delay is to understand how the prosecutor and the defendant make their decisions, and how these respond to changes in trial delay. If both parties jointly maximise expected utility, trial delay may increase or decrease the number of trials, depending upon the decision makers' attitudes towards risk. The main policy implication is that providing the criminal courts with more resources in the form of additional judges and court capacity may lengthen the trial queue rather than shorten it. This is a counterintuitive result contrary to popular belief.

Court delays and the defendant behaviour: an economic analysis

Court delays are consistently criticised as being inimical to social welfare. However, the theoretical basis for this assertion is not well established in the law and economics literature. As a first step, very little is known about the impact of court delay on the defendant's optimal plea decision. If the defendant is rational in the sense of inter temporally optimising, court delay may increase or decrease the probability of a trial depending on the defendant's bail status. Some empirical support for this theoretical proposition is found using data on plea behaviour for a selection of cases heard in NSW Australia.

Identity territory: Pamela Allen's picture books in the Australian psyche

Parsons examines the dialogic space of the picture book reading, and its co-opting of the authority of the "significant other" in relation to Pamela Allen's picture books. Mapping Australian identity theory in Allen's picture books involves recognizing Australian-ness as both formed and performed at a point of intersection between colonial, migrant, and patriarchal tropes. Each of these tropes is readable through the dynamics of theater semiotics, and each is mirrored by child maturation as embodied by a movement toward adult authority.

Geographical variation in bill size across bird species provides evidence for Allen's rule

Allen’s rule proposes that the appendages of endotherms are smaller, relative to body size, in colder climates, in order to reduce heat loss. Empirical support for Allen’s rule is mainly derived from occasional reports of geographical clines in extremity size of individual species. Interspecific evidence is restricted to two studies of leg proportions in seabirds and shorebirds. We used phylogenetic comparative analyses of 214 bird species to examine whether bird bills, significant sites of heat exchange, conform to Allen’s rule. The species comprised eight diverse taxonomic groups—toucans, African barbets, Australian parrots, estrildid finches, Canadian galliforms, penguins, gulls, and terns. Across all species, there were strongly significant relationships between bill length and both latitude and environmental temperature, with species in colder climates having significantly shorter bills. Patterns supporting Allen’s rule in relation to latitudinal or altitudinal distribution held within all groups except the finches. Evidence for a direct association with temperature was found within four groups (parrots, galliforms, penguins, and gulls). Support for Allen’s rule in leg elements was weaker, suggesting that bird bills may be more susceptible to thermoregulatory constraints generally. Our results provide the strongest comparative support yet published for Allen’s rule and demonstrate that thermoregulation has been an important factor in shaping the evolution of bird bills.
