‘Autograph of a Nation’: The Daughters of the American Revolution and the National Old Trails Road, 1910–1927

In 1912, a group of women within the National Society of the Daughters of the American Revolution (DAR) undertook to become architects of the first continuous transcontinental automobile route, to be called the ‘National Old Trails Road’ highway. Consistent with many of the private road improvement initiatives during the heyday of America's good roads movement, ‘Daughters’ in many states were involved in mapping the route and posing a variety of marking schemes that would etch upon the landscape the DAR's sponsorship of the route. In doing so, the Daughters staked an explicit claim for the DAR and for American women in the project of nation‐building, by promoting their National Old Trails Road as a culmination of Manifest Destiny. This episode highlights the interrelationship of gender and the nation. This article argues that while women function passively in nationalist rhetoric to symbolise the nation, one must also acknowledge the agency of conservative women's groups in constructing and perpetuating nationalist narratives in ways that were often surprisingly complex and not simply imitative of men.     

冷却剂参数对铣槽喷管低周疲劳寿命的影响

采用有限体积流固耦合计算方法、非线性有限元热结构耦合分析方法和局部应变法研究大面积比铣槽喷管三维再生冷却槽道在循环工作条件下的热结构变形与低周疲劳寿命,并对比分析了冷却剂质量流量与入口温度对铣槽喷管疲劳使用寿命的影响。计算结果表明,铣槽喷管热结构响应呈现复杂的三维效应,应变较大位置主要分布在与肋连接的内衬区域,喷管中部的残余应变量最大;冷却槽道低周疲劳寿命分布和热结构响应基本一致,最小寿命位于喷管中部与肋相连的内衬区域燃气侧;随冷却剂质量流量增加,铣槽喷管低周疲劳寿命不断提高;随冷却剂入口温度增加喷管尾部低周疲劳寿命值不断降低,而喷管中前部的低周疲劳寿命值却不断提高,当冷却剂入口温度为280K左右时,本文的铣槽喷管总体使用寿命达到最大。      

Impact of Combat on the Mental Health and Well‐Being of Soldiers and Marines

This presentation introduces a summary of leading edge research and recommendations for a number of changes regarding mental health needs and services for Veterans. Those Veterans who experienced combat exposure and those who have perceived their leadership negatively have greater risks for developing subsequent PTSD. Research data provide support for the use of Battlemind Training as a useful approach to prevent mental health issues at all phases of the deployment cycle. The author also challenges the current use of DSM–IVTR diagnoses with combat Veterans.     

Middle‐Class Political Activism and Middle‐Class Advantage in Relation to Public Services: A Realist Synthesis of the Evidence Base

Since the late 1960s social policy scholarship has been concerned with the distribution of the resources or benefits across social gradients. This article presents a review of the literature on one mechanism by which inequity might be produced – activism by middle‐class service‐users enabling them to capture a disproportionate share of resources. The review used the methodology of realist synthesis to bring together evidence from the UK, the USA and Scandinavian countries over the past 30 years. The aim was to construct a ‘middle‐theory’ to understand how and in which contexts collective and individual activity by middle‐class service‐users might produce inequitable resource allocation or rationing decisions that disproportionately benefit middle‐class service‐users. The article identifies four causal theories which nuance the view that it is the ‘sharp elbows’ of the middle‐classes which confer advantage on this group. It shows how advantage accrues via the interplay between service‐users, providers and the broader policy and social context.     

Lone Parents and Welfare‐to‐Work in England: A Spatial Analysis of Outcomes and Drivers

Mirroring changes across nations of the Organisation for Economic Co‐operation and Development, recent UK governments have redrawn lone parents' entitlement to social assistance benefits ever tighter around participation in the labour market. A radical shift since 2008 has been the gradual transfer of most non‐employed lone parents into the ‘activating’ Jobseekers' Allowance (JSA) regime. The enhanced conditionality requirements of this JSA regime have been justified by both paternalistic and contractualist arguments but, however justified, are built on the premise that behavioural factors drive lone parent employment outcomes, a view made increasingly forcefully under the current Coalition government. This article uses up‐to‐date administrative data at local authority level across England to provide a geographical perspective into the sub‐national changes in lone parent employment outcomes since the transfer to JSA from 2008, as well as the relevant importance of the alternative structural and behavioural accounts to these outcomes. The findings suggest that the JSA transfer has increased lone parent employment, that structural rather than behavioural drivers are more relevant causal factors and that there is good reason to be concerned about the effect of the reforms on the well‐being of lone parents and their children.     

Lone mothers' time allocations: choices and satisfactions

This paper uses the 2006 Australian Time Use Survey to examine the allocation of time to personal care, employment‐related activities, home duties, leisure and child care of lone mothers, in comparison to the time allocations of single women, women in childless couples and partnered mothers. Both primary and secondary time allocations are considered. The satisfactions that women report concerning their current time allocations are also analysed. The time use and satisfaction data are described using both tabulations and multiple regression methods. Lone mothers are shown to have similar time allocations as the other types of households, even though they have different financial and time resources. This raises the concern that lone mothers' desire or need to maintain such time allocations may lead to task overload. Consistent with this, lone mothers are found to be less satisfied with the way they allocate their time than single women and partnered mothers. The tensions associated with time use among lone mothers discussed in the literature are real, and important.     

A Canadian Population Level Analysis of the Roles of Irrational Gambling Cognitions and Risky Gambling Practices as Correlates of Gambling Intensity and Pathological Gambling

Using population data (N = 11,562) drawn from five Canadian gambling prevalence surveys conducted between 2000 and 2005, the current study investigated the relationship between irrational gambling cognitions and risky gambling practices upon (a) gambling intensity, as measured by percent of income spent on gambling and (b) tolerance, a diagnostic indicator of pathological gambling. First, we found irrational gambling cognitions and risky gambling practices to be positively related. Second, irrational gambling cognitions moderated the relationship between risky gambling practices and gambling intensity. Specifically, people engaging in risky practices, spent less of their income on gambling when they had fewer irrational gambling cognitions compared to those with more irrational cognitions. Third, irrational gambling cognitions moderated the relationship between risky gambling practices and tolerance. Of the people engaging in risky practices, those with no irrational cognitions reported lower levels of tolerance than those with at least one irrational cognition. Interactions with gender are reported and discussed. These findings demonstrate the importance of both gambling cognitions and gambling practices upon the intensity of gambling and pathological gambling.

The Realized Laplace Transform of Volatility

We introduce and derive the asymptotic behavior of a new measure constructed from high‐frequency data which we call the realized Laplace transform of volatility. The statistic provides a nonparametric estimate for the empirical Laplace transform function of the latent stochastic volatility process over a given interval of time and is robust to the presence of jumps in the price process. With a long span of data, that is, under joint long‐span and infill asymptotics, the statistic can be used to construct a nonparametric estimate of the volatility Laplace transform as well as of the integrated joint Laplace transform of volatility over different points of time. We derive feasible functional limit theorems for our statistic both under fixed‐span and infill asymptotics as well as under joint long‐span and infill asymptotics which allow us to quantify the precision in estimation under both sampling schemes.     

Bootstrap Determination of the Co‐Integration Rank in Vector Autoregressive Models

This paper discusses a consistent bootstrap implementation of the likelihood ratio (LR) co‐integration rank test and associated sequential rank determination procedure of Johansen (1996). The bootstrap samples are constructed using the restricted parameter estimates of the underlying vector autoregressive (VAR) model that obtain under the reduced rank null hypothesis. A full asymptotic theory is provided that shows that, unlike the bootstrap procedure in Swensen (2006) where a combination of unrestricted and restricted estimates from the VAR model is used, the resulting bootstrap data are I(1) and satisfy the null co‐integration rank, regardless of the true rank. This ensures that the bootstrap LR test is asymptotically correctly sized and that the probability that the bootstrap sequential procedure selects a rank smaller than the true rank converges to zero. Monte Carlo evidence suggests that our bootstrap procedures work very well in practice.     

The quality and use of regulatory analysis in 2008

This article assesses the quality and apparent use of regulatory analysis for economically significant regulations proposed by federal agencies in 2008. A nine-member research team used a six-point (0-5) scale to evaluate regulatory analyses according to criteria drawn from Executive Order 12866 and Office of Management and Budget Circular A-4. Principal findings include: (1) the average quality of regulatory analysis, though not high, is somewhat better than previous regulatory scorecards have shown; (2) quality varies widely; (3) biggest strengths are accessibility and clarity; (4) biggest weaknesses are analysis of the systemic problem and retrospective analysis; (5) budget or "transfer" regulations usually receive low-quality analysis; (6) a minority of the regulations contain evidence that the agency used the analysis in significant decisions; (7) quality of analysis is positively correlated with the apparent use of the analysis in regulatory decisions; and (8) greater diffusion of best practices could significantly improve the overall quality of regulatory analysis.
