The bajocian ammonites of Western Australia

The Bajocian (Middle Jurassic) ammonites of Western Australia are described on the basis of an extensive collection made in 1952-3 by Phillip E. Playford, who contributes a stratigraphical introduction and a geological map. In this introduction he subdivides the Jurassic sediments (total thickness at outcrop up to 550 ft.), names and defines most of the groups and formations for the first time, and elucidates complications due to lateritic alteration. All the ammonites come from the Newmarracarra Limestone (up to 38 ft. thick). The ranges of the species are determined so far as practicable. The ammonite fauna comprises at least twenty-three species (at least eleven new), now assigned to seven genera. The new collection enables Crick’s type specimens, named in 1894 on the basis of defective and inadequate material, to be reinterpreted, and necessitates complete generic revision. The age of the fauna is Middle Bajocian. Most of it belongs to the Sowerbyi Zone, but in places there is believed to be also a thin representative of the Humphriesianum Zone. A comparison (now possible for the first time) is made with the Bajocian ammonite faunas of circum-Pacific countries and central Asia: New Guinea, the Moluccas, Tibet, eastern Siberia, Alaska, western Canada, western United States, Mexico and the Andes. Photographs are given of comparable ammonites from Tibet, Canada and Argentina, not previously published photographically. Apart from the Moluccas, the peculiar Australian stephanoceratid ammonites, Pseudotoites and their allies, are not known from any of the extensive Bajocian outcrops in the Old World. Hitherto they have been thought to be confined to Western Australia. It is now shown that Pseudotoites occurs in the Moluccas, British Columbia, Alaska and Argentina, and that some rarer allied forms of Western Australia belong to the genus Zemistephanus , hitherto known only in Canada, Alaska and the United States. This distribution is held to indicate free migration across the Pacific Ocean. The regional basis of evolutionary radiation in several groups of Middle Bajocian ammonites is pointed out, and the significance of the facts for evolutionary and systematic theory is briefly stated. The Middle Bajocian stratigraphy of north-west Europe is historically summarized in order to provide a framework and scale of comparison for the Australian and circum-Pacific deposits.

On a hopeful September day in 1912, Gim Pon, a twenty-five year old Chinese man from Canton, boarded the steamship Siberia in Hong Kong harbor to sail west across the Pacific. The Siberia docked briefly in San Francisco, but Gim Pon's destination, and that of seven fellow Chinese travelers, was not California but the northern Mexican state of Sonora. In the early twentieth century, thousands of men like Gim Pon immigrated to Mexico, boosting the Chinese population there from slightly over 1,000 in 1895 to more than 24,000 in the mid-1920s. Sonora, which hugs Arizona at the United States/Mexico border, was a popular destination, and hosted the largest Chinese population of any Mexican state through the 1920s. Once in Sonora, Gim Pon adapted to life in Mexico: he changed his name to Francisco Gim, learned Spanish, and became naturalized as a Mexican citizen on February 27, 1920. Most importantly, he formed a family with Julia Delgado.

In this paper, stumpages in British Columbia are compared with those in the Pacific Northwest region of the United States where public timber is sold in highly competitive markets. In 1978, the average stumpage for public timber in the Pacific Northwest was $39.11/m3 compared to $4.58/m3 in British Columbia. Between 1963 and 1978, real stumpage prices in the Pacific Northwest (i.e. net of inflationary increases) showed an upward trend of almost 11% per annum compared to a slight downward trend for British Columbia. Although the appraisal method used by the United States Forest Service is similar to the method used in British Columbia, appraised stumpages for the British Columbia Coast are considerably lower than for western Washington.There is little doubt that the principle reason for higher stumpages in the Pacific Northwest is that all public agencies involved in timber production encourage competitive bidding for standing timber, whereas in British Columbia competitive sales of public timber have been virtually eliminated. Other reasons include tax considerations on the part of firms in the Pacific Northwest with private timber holdings, the higher average quality of the timber resource in the Pacific Northwest compared to British Columbia and the fact that forest products companies in the Pacific North west face better market opportunities, particularly with respect to plywood, than their counterparts in British Columbia. Imperfections in the Vancouver Log Market may partially explain why appraised timber values in western Washington are higher than on the British Columbia Coast.There is good reason to believe that if public timber in British Columbia was sold competitively, stumpages, in many cases, would be bid well above their appraised level and direct Crown revenues would be substantially increased, particularly in those regions of the Province where accessible, high quality stands of timber are in short supply.

AbstractThe 35 species of the genus Tachyporus Gravenhorst (Staphylindae: Tachyporinae) of North and Central America are revised. Eighteen new species are described: neomexicanus, fenyesi, and howdenorum from the southwestern United States; sharpi from Mexico and the western United States; blomae from Mexico; nigripennis from California; dimorphus, pacificus, and stacesmithi from the Pacific northwest; rulomoides and browni from southeastern Canada and the northeastern United States; and borealis, canadensis, nimbicola, inornatus, ornatus, lecontei, and flavipennis, which are transcontinental in the United States and Canada. Two European species are reported for the first time from North America: abdominalis (Fabricius) and transversalis Gravenhorst. The following new specific synonymy is proposed: tehamae Blackwelder (= californicus Horn); temacus Blackwelder, oregonus Blackwelder, and alleni Blackwelder (= mexicanus Sharp); and acaudus Say, maculipennis LeConte, and chrysomelinus var. infuscatus Bernhauer (= jocosus Say). The genus is divided into 2 subgenera of which Palporus (type species Staphylinus nitidulus Fabricius) is described as new. The subgenus Tachyporus is divided into 12 species groups. Each species is described and its distribution is mapped. The male aedeagus and the pattern of elytral chaetotaxy are illustrated for each species. Major generic characters are illustrated with the aid of scanning electron photomicrographs. Neotypes are designated for the Say species faber, jocosus, and acaudus and lectotypes are designated (when needed) for the North and Central American species described by Erichson, LeConte, Horn, Sharp, and Blatchley and for a variety described by Bernhauer. A diagnostic key for all the species is given.

Myanmar, sitting on the border between South and Southeast Asia, reflects a historically oppressive state with internal struggle as surrounding countries compete for influence. In 1990, the government promised multi-party elections only to ignore the results and imprison advocates for democracy, including Aung San Suu Kyi, the face of Myanmar’s democratic movement. Afterwards, the United States adopted economic sanctions and restricted ties with the country. Recently, leaders in Myanmar have reached out to the United States for the first time in decades. With policy towards Myanmar at a crossroads, how can the United States pursue its own interests while influencing Myanmar’s slow transition to political and economic change?

The report by Titian Ramsay Peale on birds encountered during the Wilkes Expedition was withdrawn for inaccuracy when few copies had been distributed, and re-written by John Cassin. A survey of the accounts of the petrels shows that this was not an improvement. Two important type localities for Procellaria brevipes and Thalassidroma lineata are probably wrong, and could be exchanged.

This chapter is a study of the themes of the New International Economic Order (NIEO). It begins with the notion of justice that had been constructed in imperial law to justify empire and colonialism. The NIEO was the first time a prescription was made for justice in a global context not based on domination of one people over another. In its consideration of the emergence of a new notion of justice in international law, the chapter discusses the reasons for the origins of the NIEO, and goes on to describe the principles of the NIEO and the extent to which they came into conflict with dominant international law as accepted by the United States and European states. Next the chapter deals with the rise of the neoliberal ideology that led to the displacement of the NIEO and examines the issue of whether the NIEO and its ideals have passed or whether they continue to be or should be influential in international law. Finally, the chapter turns to the ideas of the NIEO alongside new efforts at promoting a fuller account of justice by which to justify and evaluate international law.
