King Pedro IV of Aragon, royal propaganda and the tradition of royal speechwriting

In the medieval Crown of Aragon it was customary for the corts to begin with a proposicio or opening speech made by the king. These Aragonese royal speeches were not merely confined to a brief summary of the political situation or a series of points to be considered but were elaborately constructed political sermons, in which affairs of state were portrayed in terms of Christian morality and nationalist pride, with the aid of exempla drawn from the Bible and other religious and classical works. An example is the speech made by Pedro IV ‘the Ceremonious’ of Aragon against the rebellion of the Judge of Arborea in Sardinia. A copy of this speech survives written in the king's own hand which raises the interesting question of whether the kings of Aragon were themselves responsible for the ideas expressed in these speeches and for composing them or whether their efforts were confined to reading out propaganda which was primarily the creation of royal officials.     

Fearing Food: The Influence of Risk Perceptions on Public Preferences for Uniform and Centralized Risk Regulation

Public opinion features prominently in policy research because it sets bounds on the definition of policy problems and acceptable policy solutions. We contend that public opinion is also important for setting bounds on the level of government at which policy hazards are regulated by shaping preferences for uniformity of regulation and, relatedly, preferences for centralization. We offer a theoretical argument for why risk creates pressures for uniform standards and examine the extent to which preferences for uniformity and centralization are the product of fairly stable individual-level predispositions (e.g. partisanship and ideology) versus more fluid attitudes like perceptions of risk, which vary in response to crises, new information, and issue framing. We test our argument using survey data in the policy domain of food safety and find that individuals who anticipate greater risk from food-borne illness prefer more uniform food safety regulation, which translates into preferences for federal-level policymaking. Our results imply that contextual circumstances and strategic communications that influence risk perceptions can create not only generalized public demand for more regulatory policy but specific demand for uniform, centralized regulation.     

Investigating the production and distribution of plain ware pottery in the Samoan archipelago with laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

This paper presents a provenance study of 170 ceramic artifacts and 21 ceramic tiles from three islands in the Samoan archipelago using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Our analyses confirm that LA-ICP-MS can be used to differentiate between clay formations on a single island. We identify different distribution patterns for pottery recovered from lowland and highland sites on Tutuila Island. We also examine evidence for movement of pottery between islands, and find only limited evidence for such movement. Our findings suggest dynamic patterns of prehistoric interaction and site use that need to be evaluated with further data from across the archipelago.     

Cranial shape variation and phylogenetic relationships of extinct and extant Old World leaf-nosed bats

Wilson, L.A.B., Hand, S.J., López-Aguirre, C., Archer, M., Black, K.H., Beck, R.M.D., Armstrong, K.N. & Wroe, S., July 2016. Cranial shape variation and phylogenetic relationships of extinct and extant Old World leaf-nosed bats. Alcheringa 40, 509–524. ISSN 0311-5518

The leaf-nosed bats in Hipposideridae and Rhinonycteridae currently have an Old World tropical to subtropical distribution, with a fossil record extending back to the middle Eocene of Europe. The Riversleigh World Heritage fossil site in northwestern Queensland constitutes a particularly rich archive of faunal diversity for Old World leaf-nosed bats, having yielded more than 20 species. We used 2D geometric morphometrics to quantify cranial shape in hipposiderids and rhinonycterids, with the aim of referring unallocated fossil species, particularly from Riversleigh, to each family within a phylogenetic framework, and using a quantitative approach to reconstruct cranial shape for key clades in these Old World radiations. Our sample comprised 21 extant hipposiderids and rhinonycterids, 1 megadermatid and 1 rhinolophid, in which 31 landmarks were placed in lateral and ventral views, and five measurements were taken in dorsal view. The phylogeny used as the framework for this study was based on an analysis of 64 discrete morphological characters from the dentition, cranium and postcranium scored for 42 extant and fossil hipposiderids and rhinonycterids and five outgroup taxa (rhinolophids and megadermatids). The phylogenetic analysis was conducted using maximum parsimony, with relationships among selected extant taxa constrained to match the results of recent comprehensive molecular studies. Our phylogenetic results suggest that the Riversleigh leaf-nosed bats probably do not represent an endemic Australian radiation, with fossil species spread throughout the tree and several with sister-group relationships with non-Australian taxa. Discriminant analyses (DA) conducted separately on each dataset resulted in cross-validated classification success ranging from 61.9% for ventral landmarks to 71.4% for lateral landmarks. Classification of the original grouped cases resulted in success of 81% for each dataset. Of the eight fossil taxa included as unknowns in the DA, six were found to be assigned to the same group as recovered by the phylogenetic analysis. From our results, we assign the Riversleigh Miocene species Archerops annectens, Brachipposideros watsoni, Brevipalatus mcculloughi, Rhinonicteris tedfordi and Xenorhinos halli to Rhinonycteridae, and Riversleigha williamsi and Hipposideros bernardsigei to Hipposideridae. Our results support Pseudorhinolophus bouziguensis, from the early Miocene of Bouzigues in southern France, as belonging to Hipposideridae, and probably Hipposideros. The reconstructed ancestor of hipposiderids was distinguished from that of the rhinonycterids by having a shorter rostrum, and less of a distinction between the rostrum and braincase.

How Much Knowledge is Worth Knowing? An American Intellectual Historian's Thoughts on the Geschichte des Wissens

This essay investigates the origins and assesses the advantages and disadvantages of the new field known as Wissensgeschichte from the perspective of an American intellectual historian. It argues that while some historians of science may be ready to embrace a new identity as historians of knowledge, this terminology remains baggy and invites facile applications of Foucauldian theory. The essay concludes with the hope that the history of knowledge approach may instead open up new avenues for conversation and collaboration between historians of science and garden variety historians.     

New material referable to Wakaleo (Marsupialia: Thylacoleonidae) from the Riversleigh World Heritage Area,northwestern Queensland: revising species boundaries and distributions in Oligo/Miocene marsupial lions

Gillespie, A.K., Archer, M., Hand, S.J. & Black, K.H., 2014. New material referable to Wakaleo (Marsupialia: Thylacoleonidae) from the Riversleigh World Heritage Area, northwestern Queensland: revising species boundaries and distributions in Oligo/Miocene marsupial lions. Alcheringa 38, 513–527. ISSN 0311–5518.

New material of Wakaleo oldfieldi and W. vanderleueri from the Miocene freshwater limestones of the Riversleigh World Heritage Area, northwestern Queensland, is described. This material includes the first known upper dentition of W. oldfieldi and dentaries of both species bearing the previously undescribed and morphologically distinct M₃. Previously, the two species were distinguished only by size differences in P3 and the size of P₃ relative to M1. Wakaleo oldfieldi exhibits a more plesiomorphic M₃ that retains a well-developed talonid basin in contrast to W. vanderleueri, which has lost this structure. The phyletic succession and geological occurrences of Wakaleo species make this genus an important taxon in biochronological analyses of Australian Cenozoic assemblages. At Riversleigh, W. oldfieldi is found in deposits allocated to Faunal Zone B and Faunal Zone C, which are regarded as early and middle Miocene in age, respectively. The presence of this species in the Kutjamarpu Local Fauna of central Australia suggests that fauna may be of a similar age. Broader faunal correlations have suggested Faunal Zone C correlates with the middle Miocene Bullock Creek Local Fauna, which contains the more derived W. vanderleueri. Based on stage-of-evolution arguments, W. oldfieldi should occur in older deposits than those yielding W. vanderleueri. The presence of both species of Wakaleo in Faunal Zone C assemblages at Riversleigh suggests that current presumptions about the contemporaneity of the many Faunal Zone C Sites should be examined more rigorously.

PUBLIC INFORMATION ON SOCIAL CHANGE: TV COVERAGE OF WOMEN IN THE WORKFORCE*

This article analyzes the thematic and visual content of ten years of nightly television news coverage of women in the workforce and employment discrimination. The authors find that the total amount of coverage is small, the visual context often undercuts the usually anti-discriminatory text, and NBC provided the most coverage. The possible sources of these patterns are examined: the elite newspaper agents, male domination of network news, decision-making, cultural definitions of event news, and consensus values and news controversy.     

EXURBANIZATION AS A COMPONENT OF MIGRATION: A CASE STUDY IN OXFORD COUNTY, ONTARIO

In this paper exurbanization is regarded as a process involving the movement of a household from an urban area to another location beyond the contiguously built-up urban region but within its extensive commuting field. The primary definitive feature is that one or more persons within the household retains regular employment ties with the urban area. Although various influences on the inter-and intra-urban migration of households have been considered extensively in the migration literature (Clark 1982), exurbanization has yet to be placed in the context of this literature and examined with similar rigour. The issue, to paraphrase Rossi and Shlay (1982), is not just why households move, but why they choose to move where they do - that is, why have some become exurbanite households?
