In situ and ex situ neutron reflectivity is used to characterize annealed regioregular-P3HT/PCBM bilayers. In situ annealing of a 20 nm PCBM/35 nm P3HT bilayer at 170 °C reveals rapid mixing of PCBM and P3HT to produce a polymer-rich layer that contains around 18–20% PCBM. Samples with three different thicknesses of P3HT layer are ex situ annealed at 140 °C. This again reveals migration of PCBM into the P3HT and vice versa, with the polymer-rich layer in the 20 nm PCBM/35 nm P3HT sample containing 19% PCBM. Complete migration of the entire PCBM layer into the P3HT layer is observed for a 20 nm PCBM/80 nm P3HT bilayer. The robustness of fitted model composition profiles, in comparison with real-space imaging of sample surface morphology and previous work on annealed P3HT/PCBM bilayer compositions, is discussed in detail.

The Manchester Chamber of Commerce established the Manchester Testing House in 1895, and introduced uniform yarn contracting rules in 1897. The chamber made these institutional “innovations” to deal with the nefarious practice of “short-reeling.” This case study explains how and why merchants were crucial to undoing weaknesses in domestic —and to some extent foreign—legislation to overcome this fraudulent activity. We argue that the Testing House and uniform contract were tantamount to developing a quasi-legal system such that private standards established through cooperative agreements had legal sanction. Our study shows how institutions evolved to improve governance along the supply chain for this highly specialized export-orientated industry. This article contributes to the growing literature on historical markets, institutions, and standards. Based on extensive archival sources, we show how specific and complementary commercial institutions developed within grounded notions of governance rather than abstracted spaces of market exchange.

The Numeniini is a tribe of 13 wader species (Scolopacidae, Charadriiformes) of which seven are Near Threatened or globally threatened, including two Critically Endangered. To help inform conservation management and policy responses, we present the results of an expert assessment of the threats that members of this taxonomic group face across migratory flyways. Most threats are increasing in intensity, particularly in non-breeding areas, where habitat loss resulting from residential and commercial development, aquaculture, mining, transport, disturbance, problematic invasive species, pollution and climate change were regarded as having the greatest detrimental impact. Fewer threats (mining, disturbance, problematic native species and climate change) were identified as widely affecting breeding areas. Numeniini populations face the greatest number of non-breeding threats in the East Asian-Australasian Flyway, especially those associated with coastal reclamation; related threats were also identified across the Central and Atlantic Americas, and East Atlantic flyways. Threats on the breeding grounds were greatest in Central and Atlantic Americas, East Atlantic and West Asian flyways. Three priority actions were associated with monitoring and research: to monitor breeding population trends (which for species breeding in remote areas may best be achieved through surveys at key non-breeding sites), to deploy tracking technologies to identify migratory connectivity, and to monitor land-cover change across breeding and non-breeding areas. Two priority actions were focused on conservation and policy responses: to identify and effectively protect key non-breeding sites across all flyways (particularly in the East Asian- Australasian Flyway), and to implement successful conservation interventions at a sufficient scale across human-dominated landscapes for species’ recovery to be achieved. If implemented urgently, these measures in combination have the potential to alter the current population declines of many Numeniini species and provide a template for the conservation of other groups of threatened species.

A substantial literature documents the importance of trademarks and brands to business success. How does this relationship change when we enlarge our focus from individual firms to industries and nations? This articles examines the dominance of Danish bacon in Britain between the late nineteenth and early twentieth centuries. We argue that this supremacy required state intervention and cooperation between government and producers to underpin high and consistent levels of quality throughout the supply chain, both of which were necessary to ensure the successful marketing of “Danish” bacon. In Britain, by contrast, state intervention to increase bacon production was only partially successful because it was undermined by a nineteenth-century legacy of uncoordination and deregulation. Such weaknesses affected the supply of appropriate pigs and the production of bacon that was uniform in quality, and ultimately negated the efforts of the Ministry of Agriculture and Fisheries to promote a “British” bacon brand.

We report on an influenza B outbreak in an Ontario long-term care facility in which 2 immunized residents receiving oseltamivir prophylaxis for at least 5 days developed laboratory-confirmed influenza B infection. All isolates were tested for the most common oseltamivir resistance, and none of them had resistance identified.

This reassessment of the importance of trademarks in business during the nineteenth and early twentieth centuries reveals that the focus by business historians on the beverage and processed-foodstuff industries has resulted in comparative neglect of the textile and metal-fabrication industries. The trademark histories of the latter two show that they followed their own paths, which resulted in their adopting three solutions to trademark issues that differed sharply from the approaches taken by the former two. The textile and metalfabrication sectors participated heavily in the evolution of an international regime to protect intellectual property; featured prominently in the development of patents in trademarks and trade names; and devised unique institutional solutions to the emerging problem of conflicting private marks in the Lancashire cotton-textile and Sheffield edge-tool industries. The history of these two industries indicates that trademark protection was not sufficient to ensure international competitiveness and long-run survival.

The abbey of St Augustine was named for Augustine ‘Apostle of the English’, as was its associated parish church, but was governed from its foundation by canons of the rule of St Augustine of Hippo. The two Augustines in the equation were a source of confusion. A reconstruction of the abbey's lost liturgical calendar suggests that the chapter sought to exploit this uncertainty in the matter of the foundation history of their abbey, with the aim of displacing, in the popular mind, the humble ‘English’ saint of the dedication in favour of the ‘Latin’ founder of the canons' rule.

The negative effects of prenatal substance exposure on neurobiological and psychological development and of early adversity are clear, but little is known about their combined effects. In this study, multilevel analyses of the effects of prenatal substance exposure and early adversity on the emergence of neurobehavioral disinhibition in adolescence were conducted. Neurobehavioral disinhibition has previously been observed to occur frequently in multiproblem youth from high-risk backgrounds. In the present study, neurobehavioral disinhibition was assessed via behavioral dysregulation and poor executive function composite measures. Data were drawn from a prospective longitudinal investigation of prenatal substance exposure that included 1,073 participants followed from birth through adolescence. The results from latent growth modeling analyses showed mean stability but significant individual differences in behavioral dysregulation and mean decline with individual differences in executive function difficulties. Prior behavioral dysregulation predicted increased executive function difficulties. Prenatal drug use predicted the emergence and growth in neurobehavioral disinhibition across adolescence (directly for behavioral dysregulation and indirectly for executive function difficulties via early adversity and behavioral dysregulation). Prenatal drug use and early adversity exhibited unique effects on growth in behavioral dysregulation; early adversity uniquely predicted executive function difficulties. These results are discussed in terms of implications for theory development, social policy, and prevention science.

This article examines the misrepresentation of American beef in the British market between c. 1890 and c. 1913. We examine the complaints voiced by British consumers, producers, and retailers and we discuss the response of the British government and the United States Department of Agriculture. A new dataset is employed to calculate the price premiums that could be earned from the misrepresentation of beef according to geographic origin. While considerable premiums could be earned by “passing-off” American beef as British in the 1890s, these premiums declined during the 1900s. Particular emphasis is placed on the inability of the British government to act unilaterally on meat marking. This article also considers origin as a means of distinguishing between categories of nonbranded goods. Yet “origin” has many dimensions. Not only does it indicate provenance, it sometimes signals quality associated with provenance while also serving as the basis for protectionist responses. This article therefore contributes to the broader debates surrounding origin marking as a commercial and legal phenomenon.
