On the pathwise approximation of stochastic differential equations

We consider one-step methods for integrating stochastic differential equations and prove pathwise convergence using ideas from rough path theory. In contrast to alternative theories of pathwise convergence, no knowledge is required of convergence in pth mean and the analysis starts from a pathwise bound on the sum of the truncation errors. We show how the theory is applied to the Euler-Maruyama method with fixed and adaptive time-stepping strategies. The assumption on the truncation errors suggests an error-control strategy and we implement this as an adaptive time-stepping Euler-Maruyama method using bounded diffusions. We prove the adaptive method converges and show some computational experiments.Comment: 21 page

Attachment in adults with high-functioning autism

This study assessed attachment security in adults with high-functioning autism spectrum disorders, using the Adult Attachment Interview (AAI; George, Kaplan & Main, 1996). Of twenty participants, three were classified as securely attached, the same proportion as would be expected in a general clinical sample. Participants’ AAIs were less coherent and lower in reflective function than those of controls, who were matched for attachment status and mood disorder. A parallel interview suggested that some aspects of participants’ responses were influenced by their general discourse style, while other AAI scale scores appeared to reflect their state of mind with respect to attachment more specifically. There was little evidence that attachment security was related to IQ, autistic symptomatology or theory of mind. This study suggests that adults with autism can engage with the AAI and produce scoreable narratives of their attachment experiences, and a minority demonstrate secure attachment

'Sectarian Secret Wisdom' and Nineteenth-Century Radicalism: The IWMA in London and New York

An analysis of the urban context of the development of the IWMA in large urban centres, analysing the support it gained, its transnational links and associations, and its impact on the development of the radical platform

Tabled Labels: Consumers Eat Blind While Congress Feasts on Campaign Cash

As the Senate prepared to vote on its version of the U.S. Department of Agriculture's (USDA) budget, Public Citizen released an investigation to illustrate how big agribusiness used millions of dollars in lobbying expenditures and campaign contributions, and a network of Washington insiders with close connections to the Bush administration and Congress, to thwart a consumer-friendly provision mandating country-of-origin labeling, popularly known as COOL.Mandatory country-of-origin labeling would require beef, pork, lamb, fresh and frozen fruits and vegetables, fish, and peanuts to be labeled with where they were raised, grown or produced. Although the 2002 Farm Bill stipulated that the new program be implemented by September 2004, mandatory COOL has been postponed by Congress -- where lawmakers are under intense pressure from the meat and grocery industries -- for two years. In June, the U.S. House of Representatives voted to once again delay COOL's implementation for meat until 2007. Industry is strongly lobbying the Senate to either delay the funding for the USDA to work on COOL or turn it into a "voluntary" program.Public Citizen analyzed donations from 19 companies and trade associations, each of which has announced opposition to mandatory country-of-origin labeling and has registered to lobby against COOL. They have contributed a total of $12.6 million to candidates for Congress and in soft money to the Republican and Democratic parties since 2000.These companies have focused their giving on 64 members of Congress who have sponsored a bill to replace the mandatory country-of-origin requirement with a voluntary one, which is considerably weaker and does not empower consumers with the right to know where their food is from. Instead, it offers industry a way to hide critical information from the public. These 64 members, accounting for only 12 percent of Congress, have received 28 percent of contributions to candidates from the COOL foes

"The Local in the Global": memories of northern industrial protest in a transnational context, 1880-1930

This article locates memories of northern industrial protest in the context of recent debates about transnationalism. It focuses on key events and personalities that were formative for the radical platform in the heartland of the industrial north, notably Peterloo, Chartism and the agitation surrounding Gerrard Winstanley and the Diggers. Analysing the importance of these memories in sustaining a northern radical identity, it scrutinises the transmission of images of martyrdom and dissent to new world situations, particularly to the Australian colonies and to New Zealand. Examining the rhetoric of the radical platform, this article argues for the centrality of memories of radical dissent for the emergence of new labour parties in the broader White empire. It also analyses the significance of memories of dispossession for the platforms of radical politicians who sought to shake off the legacy of the “old world.” Further, this article explores the concept of a northern radical diaspora, and re-examines the factors that allowed memories of the popular politics of the nineteenth-century in the industrial north to gain a renewed significance in 'new world' situations

A virus created radical moment: Not to be missed?

I'm sitting in splendid isolation on a lush hillside above a Cretan village, where even the patriarchal kafeneio is closed. Outside its shuttered face a group of old men sit, less than socially distant, defying spasmodic police surveillance. A few kilometres away people queue obediently outside the supermarket, clutching in their plastic gloved hands the required Out-of-Home pass and their ID. There are health concerns, even though the island of 650,000 souls has precious few Covid-19 cases and only one death, but such melancholia is hardly new. Crete is awash with chemists, testing one's blood pressure a daily routine. Notwithstanding the benefits of the Mediterranean diet it’s tempting to note that Hippocrates hailed from hereabouts and that hypochondria stems from Ancient Greek. There is real fear, though not so much of the virus per se but of what lies ahead. As I write the island is closed for business. The tourism-oiled life blood of the local economy congeals. With cafes, tavernas, hotels, even beaches, empty of purpose, unemployment and debt soars. The Orthrus-headed threat of poverty and hunger hangs in the air. The questions on everybody's lips are 'when will this end?' and ‘will we, do we, want to return to normal?' At this moment, if assuredly we are not all in this together, from capitalist to peasant, humanity faces a fragile future

The dose-response relationship between training load and aerobic fitness in academy rugby union players

© 2018 Human Kinetics, Inc. Purpose: To identify the dose-response relationship between measures of training load (TL) and changes in aerobic fitness in academy rugby union players. Method: Training data from 10 academy rugby union players were collected during a 6-wk in-season period. Participants completed a lactate-threshold test that was used to assess VO 2 max, velocity at VO 2 max, velocity at 2 mmol/L (lactate threshold), and velocity at 4 mmol/L (onset of lactate accumulation; vOBLA) as measures of aerobic fitness. Internal-TL measures calculated were Banister training impulse (bTRIMP), Edwards TRIMP, Lucia TRIMP, individualized TRIMP (iTRIMP), and session RPE (sRPE). External-TL measures calculated were total distance, PlayerLoad™, high-speed distance > 15 km/h, very-high-speed distance > 18 km/h, and individualized high-speed distance based on each player’s vOBLA. Results: A second-order-regression (quadratic) analysis found that bTRIMP (R 2 = .78, P = .005) explained 78% of the variance and iTRIMP (R 2 = .55, P = .063) explained 55% of the variance in changes in VO 2 max. All other HR-based internal-TL measures and sRPE explained less than 40% of variance with fitness changes. External TL explained less than 42% of variance with fitness changes. Conclusions: In rugby players, bTRIMP and iTRIMP display a curvilinear dose-response relationship with changes in maximal aerobic fitness
