Incorrect Information

One of New Zealand’s last horse tramways, the Devonport and Lake Takapuna Tramway Company has been largely neglected by historians, and those who have reported on it often include or imply incorrect information. This has resulted in a universally negative opinion of the tramway that briefly shuttled passengers between Victoria Wharf and Cheltenham Beach in Devonport, Auckland, between 1886 and 1888. This article examines the company’s history from the perspectives of those who witnessed its rise and fall, and includes technical details from primary sources, observations by reporters, and additional information derived from photographs, maps, and government documents.

<p>A holistic evaluation of agricultural systems requires mechanistic understanding of physical, chemical and biological interactions both aboveground and belowground, yet obtaining this information on commercial farms is a challenging task. In order to support practical decision making by commercial producers, it is therefore necessary to identify system-wide performance indicators that are observable presently and cost-effectively. Data acquired through commercial soil testing satisfy these conditions; however, the relationship between the density of information — thus the cost of testing — and the value of information as a guideline for on-farm managerial changes is not well-understood.</p><p>Using high-resolution soil data from the North Wyke Farm Platform in the UK as a case exemplar, this solicited talk discusses theoretical and computational frameworks to quantify the value of an information package defined by soil testing strategies. A bootstrapping experiment revealed that the information value is often a concave function of the spatial sampling frequency, indicating that “half-hearted” soil data are unlikely to be able to inform optimal farm management. On the other hand, a high degree of serial correlation as well as atemporal inter-variable correlation resulted in some measurements identified as being redundant, as the incremental value of additional information was often found to be small and occasionally negative. Given the time and budgetary constraints, therefore, it is suggested that more effort should be spent on snapshot spatial sampling of a small number of variables, rather than continuous spot sampling of a large number of variables.</p>

This chapter outlines an international environmental history of whaling in the South Seas (the Southern Atlantic, Indian and Pacific Oceans). Pelagic (ie., deep-sea) whaling was not discretely national. “American” whaling, as traditionally understood, existed as part of a broader ecological and economic phenomenon which included whalers from other nations. Application of “American,” “British” and other national labels to an ocean process that by its nature crossed national boundaries has occluded a full understanding of whaling’s international nature, a fullness which begins with whaling community diaspora spread across the North Atlantic from the United States to Britain and France, and which extends to the varied locations where whalers hunted and the yet other locations to which they returned with their catch. Ocean archives—the Saint Helena Archive, the Cape Town Archive Repository, and the Brazilian Arquivo Nacional—and a reinterpretation of published primary sources and national whaling historiographies reveal the fundamentally international nature of “American” pelagic whaling, suggesting that an undue focus on US whaling data by whaling historians has likely underestimated the extent of turn-of-the-nineteenth-century pelagic whaling.

SUMMARYDNA restriction endonuclease (HaeIII andHindIII) total digest and 16S and 23S ribosomal (r)RNA gene patterns (ribopatterns) were determined for 18 isolates ofCampylobacter jejunifrom three separate outbreaks of diarrhoea in the north of England. Strains were also characterized by biotyping, serotyping and phage typing. Comparisons of the DNA patterns by visual and numerical methods revealed five distinct strain groupings with clear differences between isolates from different outbreaks as well as some heterogeneity between strains within the community outbreak and one of the school outbreaks. An excellent correlation was observed between the genomic DNA fingerprints data and the Preston bacteriophage group, both of which gave better discrimination than biotyping and serotyping alone or in combination. Only one phage group (PG 37) was not confirmed by the DNA data. DNA fingerprints therefore provide additional information of value in studying the epidemiology of outbreaks ofC. jejuni.

New records and possible range extensions are reported on 45 bird species (ca 25% of the 167 species recorded during surveys) in the Bophirima district of the North-West Province, South Africa. The findings were compared with data in The Atlas of Southern African Birds. The main reasons for these new records may be ascribed to the low number of visits during the atlas project, higher precipitation during the time of our observations versus that of the atlas project, and possibly an increased suitability of the area for some bird species due to human habitation. These new records also provide additional information that may be useful in conservation planning, especially in arid areas. Heuningvlei Pan in particular, should be considered for additional conservation measures.

Highly Correlated

We provide a methodology to estimate a global credit risk factor from credit default swap (CDS) spreads that can be very useful for risk management. The global risk factor (GRF) reproduces quite well the different episodes that have affected the credit market over the sample period. It is highly correlated with standard credit indices, but it contains much higher explanatory power for fluctuations in CDS spreads across sectors than the credit indices themselves. The additional information content over iTraxx seems to be related to some financial interest rates. We first use the estimated GRF to analyze the extent to which the eleven sectors we consider are systemic. After that, we use it to split the credit risk of individual firms into systemic, sectorial, and idiosyncratic components, and we perform some analyses to test that the estimated idiosyncratic components are actually firm-specific. The systemic and sectorial components explain around 65% of credit risk in the European industrial and financial sectors and 50% in the North American sectors, while 35% and 50% of risk, respectively, is of an idiosyncratic nature. Thus, there is a significant margin for portfolio diversification. We also show that our decomposition allows us to identify those firms whose credit would be harder to hedge. We end up analyzing the relationship between the estimated components of risk and some synthetic risk factors, in order to learn about the different nature of the credit risk components.

Phylogeographic study across codistributed taxa provides temporal and spatial perspectives on the assemblage of communities. A repeated pattern of intraspecific diversification within several taxa of the Pacific Northwest has been documented, and we contribute additional information to this growing data set. We analyzed variation in two mitochondrial genes (cytochrome b and control region) for the black bear (Ursus americanus) and expand previous analyses of phylogeographic variation. Two lineages (coastal and continental) exist; the coastal lineage extends along the Pacific coast from the Takhin River north of Glacier Bay National Park, southeast Alaska, to northern California, whereas the continental lineage is more widespread, occurring from central Alaska to the east coast. Both lineages occur along the coast of southeast Alaska, where interlineage divergence ranged from 3.1 to 3.6% (uncorrected p distances). Multiple lineages of other species have also been identified from southeast Alaska, indicating a complex history for the assembly of biotic communities along the North Pacific coast. The overlapping of the distributions of the black bear lineages with those of other birds and mammals suggests comparable routes of colonization.

Scholars regard the March on Washington Movement (MOWM) as a forerunner of the postwar Civil Rights movement. Led by the charismatic A. Philip Randolph, MOWM scored an early victory when it forced the Roosevelt Administration to issue a landmark executive order that prohibited defense contractors from practicing racial discrimination. This book recalls that triumph, but also looks beyond Randolph and the MOWM's national leadership to focus on the organization's evolution and actions at the local level. Using personal papers of MOWM members such as T.D. McNeal, internal government documents from the Roosevelt administration, and other primary sources, the book highlights how local affiliates fighting for a double victory against fascism and racism helped the national MOWM accrue the political capital it needed to effect change. The book details the efforts of grassroots organizers to implement MOWM's program of empowering African Americans via meetings and marches at defense plants and government buildings and, in particular, focuses on the contributions of women activists like Layle Lane, E. Pauline Myers, and Anna Arnold Hedgeman. Throughout he shows how local activities often diverged from policies laid out at MOWM's national office, and how grassroots participants on both sides ignored the rivalry between Randolph and the leadership of the NAACP to align with one-another on the ground.

An extensive high-resolution geophysical survey covering 2 km2was undertaken to the north of Stonehenge in June and October 2011. The survey is important in providing, for the first time, abundant detail on the form and structure of the Stonehenge Cursus, including the recognition of entrances in both of the long sides. Much additional information about the internal form of round barrows in the Cursus Round Barrow Cemetery, the course of the Avenue, the course of the so-called Gate Ditch, and numerous tracks and early roads crossing the landscape was recorded. A series of previously unrecognized features were identified: a pit-arc or cove below a barrow on the west side of King Barrow Ridge, a square-shaped feature surrounded by pits on the east side of Stonehenge Bottom, and a linear ditch on the same solstical axis, and parallel to, the southern section of the Stonehenge Avenue. An extensive scatter of small metallic anomalies marking the position of camping grounds associated with the Stonehenge Free Festival in the late 1970s and early 1980s raise interesting conservation and management issues.

Abstract The China Meteorological Administration (CMA)’s tropical cyclone (TC) database includes not only the best-track dataset but also TC-induced wind and precipitation data. This article summarizes the characteristics and key technical details of the CMA TC database. In addition to the best-track data, other phenomena that occurred with the TCs are also recorded in the dataset, such as the subcenters, extratropical transitions, outer-range severe winds associated with TCs over the South China Sea, and coastal severe winds associated with TCs landfalling in China. These data provide additional information for researchers. The TC-induced wind and precipitation data, which map the distribution of severe wind and rainfall, are also helpful for investigating the impacts of TCs. The study also considers the changing reliability of the various data sources used since the database was created and the potential causes of temporal and spatial inhomogeneities within the datasets. Because of the greater number of observations available for analysis, the CMA TC database is likely to be more accurate and complete over the offshore and land areas of China than over the open ocean. Temporal inhomogeneities were induced primarily by changes to the nature and quality of the input data, such as the development of a weather observation network in China and the use of satellite image analysis to replace the original aircraft reconnaissance data. Furthermore, technical and factitious changes, such as to the wind–pressure relationship and the satellite-derived current intensity (CI) number–intensity conversion, also led to inhomogeneities within the datasets.

Aim of study: This study focused on the sensory evaluation and consumer preferences of foal meat depending on the animal slaughter age (13 and 26 months) and finishing diet (standard and linseed concentrate).Area of study: It was developed in two localities in the north of Spain: Orense and Pamplona.Material and methods: The sensory study was conducted by a 10-member trained and a 474-consumer panel.Main results: The trained panel described meat from both, 13 and 26-months old foals similar between each other. On the contrary, consumers considered meat from the younger group to be juicier and tenderer, being juiciness and tenderness (p<0.05), the most important clues for their global acceptance. No differences were found in either the trained or the consumer panel due to the finishing diet. The consumers test was carried out in two Spanish cities (Pamplona and Orense. Two scenarios were considered: without and with supplementary information about the foal meat production. The additional information disclosed about foal meat had a positive effect on Pamplona consumers’ assessments.Research highlights: City and information level are essential factors to introduce foal meat in the market. The lack of knowledge about foal meat and its low presence in meat markets make it necessary to develop further sensory studies; to obtain foal meat description patterns, and to get to know consumers’ likings.
