Statistics as the science of government: The stillborn British Empire statistical bureau, 1918–20

The 1920 British Empire Statistical Conference was the direct outcome of the Dominions Royal Commission's Final Report, which had spelt out the need to increase the uniformity and comparability of statistics originating from various parts of the Empire and had proposed setting up an imperial central statistical office. Over 24 days, delegates debated a large number of topics, ranging from the practical and empirical subject matters of statistical inquiry to more abstract issues such as the nature and object of statistical data collection and analysis, and to the problems raised by the establishment of a statistical bureau that would operate on an unprecedented scale. This article seeks to understand why, despite apparently favourable conditions, this project soon ended in complete failure. The reasons must be sought in the neatly distinctive outlooks held by the British government and Dominion representatives as regards the function of statistics for the purpose of government, in the quite different bureaucratic settings that embodied and sustained these views, as well as in the tensions and centrifugal pressures that acted upon inter-imperial relations following the Great War.     

A new Late Ordovician microdomatid gastropod genus from Seville,south west Spain,with a revision of Ordovician Microdomatoidea

A new microdomatid gastropod, Eopagodea sevillana gen. and sp. nov., is described from the Late Ordovician (pre-Hirnantian Ashgill) limestones of Seville, Ossa Morena Zone, Spain. Palaeozoic microdomatids lived in shallow-water environments and were restricted to warm-water regions. Occurrence of microdomatid gastropods in the pre-Hirnantian Ashgill limestones of the Cerrón del Hornillo syncline (Ossa Morena Zone, Spain) is interpreted as an example of an influx of warm-water faunal elements into the otherwise cool to cold climate of the Mediterranean region during a short-termed, pre-Hirnantian increase of palaeotemperatures. The Late Ordovician microdomatid genus Daidia Wilson, 1951, is revised and two new Late Ordovician (Ashgill) subspecies of Daidia cerithioides (Salter, 1859) are described: Daidia cerithioides sewardensis n. subsp. from the Don River area of the York Mountains, Seward Peninsula, western Alaska, and Daidia cerithioides wilsonae n. subsp. from the Little East Lake Formation of northwestern Maine.     

The lower jaw and dentition of the traversodontid Exaeretodon riograndensis Abdala,Barberena & Dornelles,from the Brazilian Triassic (Santa Maria 2 Sequence,Hyperodapedon Assemblage Zone)

Exaeretodon riograndensis Abdala, Barberena, & Dornelles, 2002 Abdala, F., Barberena, M.C. and Dornelles, J.E.F. 2002. A new species of the traversodontid cynodont Exaeretodon from the Santa Maria Formation (Middle/Late Triassic) of Southern Brazil. Journal of Vertebrate Paleontology, 22: 313–325. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] is the most abundant traversodontid preserved in the basal Santa Maria 2 Sequence (Hyperodapedon Assemblage Zone), southern Brazil and is closely related to Exaeretodon argentinus Cabrera, 1943 Cabrera, A. 1943. El primer hallazgo de terápsidos en la Argentina. Notas del Museo de La Plata, Paleontología, 8: 317–331.  [Google Scholar] from the Ischigualasto Formation, Argentina. Previous anatomical studies of E. riograndensis have focused mainly on cranial material and little is known about the morphology of its lower dentition or postdentary bones. We describe the first fairly complete postdentary series of the mandible of E. riograndensis and provide additional information on its lower dentition. The postdentary bones of E. riograndensis include a complex coronoid, an angular with a delicate reflected lamina and a stout retroarticular process of the articular, contrasting with the morphology reconstructed for Argentinean specimens, which possess a small retroarticular process. Apart from that, the postdentary bones do not differ significantly from those known for E. argentinus, a fact expected due to the great similarity between other skeletal features of these species. Furthermore, the lower postcanines of E. riograndensis have virtually the same structure as those of E. argentinus, with an approximate quadrangular shape in occlusal view. Moreover, the transverse cusp row is placed anteriorly and comprises a lingual and a buccal cusp, and the occlusal basin delimited by the four main cusps is relatively deep. The new material does not add any taxonomically diagnostic features to E. riograndensis. However, the fossils greatly improve our understanding of the anatomy of the Brazilian species.     

New data on the singularly rare ‘cockroachoids’ from Xiaheyan (Pennsylvanian; Ningxia,China)

Wei, D.D., Béthoux, O., Guo, Y.X., Schneider, J.W. & Ren D., 2013. New data on the singularly rare ‘cockroachoids’ from Xiaheyan (Pennsylvanian; Ningxia, China). Alcheringa 37, 547–557. ISSN 0311-5518.

Additional material of stem-Dictyoptera, or ‘cockroachoids’, is described from the Early Pennsylvanian Xiaheyan locality (Zhongwei City, Ningxia Hui Autonomous Region, China). New specimens belonging to Qilianiblatta namurensis Zhang et al., 2012 Zhang, Z., Schneider, J.W. & Hong, Y., 2012. The most ancient roach (Blattida): A new genus and species from the earliest Late Carboniferous (Namurian) of China, with discussion on the phylomorphogeny of early blattids. Journal of Systematic Palaeontology 11, 27–40.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar] are described, as are several specimens belonging to a new species (viz., Kinklidoblatta youhei sp. nov.). Three further specimens might represent additional species, to be better documented before they could be formally named. The occurrence of a ‘vannus’ in forewings of K. youhei sp. nov. is demonstrated, and discussed in the light of data on extant Dictyoptera. The low abundance and comparatively low diversity of the group in the locality is challenging, and might be a consequence of taphonomic bias.

Parental Migration,Intergenerational Obligations and the Paradox for Left-Behind Boys in Rural China

Drawing on in-depth interviews with caregivers of left-behind children (LBC) in rural China, this article seeks to explore their understanding of migration motives and the social process of taking on care-giving roles for LBC. The authors argue that there are underlying socio-cultural explanations pertaining to economic motives for migration; such as, making contributions to social events (weddings and funerals) in village life, and fulfilling social obligations for left-behind sons’ futures. Parents migrate to save for sons’, but not daughters’, adult lives. Grandparents, particularly on the paternal side, are expected to fulfil social obligations to care for left-behind grandchildren, even without immediate financial returns. These suggest that left-behind boys, and in particular boys cared for by paternal grandparents, may be at greater risk than other LBC, as they may receive even fewer resources in the form of remittances from migrant parents in their early childhood.     

De la controverse aux règles de la méthode de discussion : La métamorphose Pascalienne de la dispute sur le vide

Pascal’s Expériences nouvelles touchant le vide (1647) outlines a physical demonstration that aims to put to an end controversies between plenists and vacuists. The traditional form of the dispute with which Pascal wanted to break, however, finds itself reactivated by Étienne Noël, who takes up again the plenist objections which the Expériences nouvelles only consider as possible the better to refute them. Pascal’s letters Au très révérend père Noël and À Monsieur Le Pailleur on the contrary permit one to define a field of disputation different from the one which Noël perpetuates. Pascal subordinates the dispute to the recognition of common epistemological principles: the antithetical discussion about the vacuum should be governed by methodological criteria accepted by all. In contrast with the model of the learned dispute, Pascal thus defines a radically new model: the scientific dispute.     

A ‘New’ Commonwealth for Britain? Negotiating Ghana's Pan-African and Asian Connections at the End of Empire (1951–8)

This article examines to what extent Nkrumah's Pan-African ambitions and Asian connections altered the meaning of the ‘new’ Commonwealth for British policy-makers. It discusses India's influence on British political options in the Gold Coast during the negotiations for independence and Commonwealth membership and assesses the impact of Ghana's Pan-Africanism on two major facets of Commonwealth politics: Britain's ability to balance its relations with the Commonwealth and France, the other main European actor in Africa; and Britain's capacity to maintain the idea of a common heritage, which Pan-African projects like the Ghana–Guinea Union threatened to disrupt.
