Shame and Ostracism: Union Army Deserters Leave Home

During the Civil War not all men served honorably and this was known by everyone in their communities. We study how shame and ostracism affect behavior by examining whether men who deserted from the Union Army, and who faced no legal sanctions once the war was over, returned home or whether they moved and re-invented themselves. We build a unique panel data set that provides us with a control group for deserters because we can identify men who deserted but then returned to fight with their companies. We find that, compared to non-deserters and returned deserters, deserters were more likely to move both out of state and further distances. This effect was stronger for deserters from pro-war communities. When deserters moved they were more likely to move to anti-war states than non-deserters. Our study provides a rare test of the empirical implications of emotion. While both shame and ostracism would push deserters out of their home community, we find no evidence that deserters faced economic sanctions.

Power Couples: Changes in the Locational Choice of the College Educated, 1940-1990

The rise of the dual career household is a recent phenomenon spurred by the increase in married women's labor force participation rates and educational attainment rates. Compared to traditional households these households must solve a colocation problem. This paper documents trends in locational choice between large and small metropolitan areas and non-metropolitan areas by household type from 1940 to 1990. We find that college educated couples are increasingly concentrated in large metropolitan areas and attribute at least half of this increase to the growing severity of the colocation problem. We also find that the relative returns for a college-educated couple of being in a large relative to a small city have increased across decades. Our results suggest that because skilled professionals are increasingly bundled with an equally skilled spouse, smaller cities may experience reduced inflows of human capital relative to the past and therefore become poorer. We examine how the relationship between rankings of university graduate programs and city size has changed between 1970 and 1990 to provide suggestive evidence on the importance of city size to firms' ability to attract the best workers.

Changes in the Value of Life: 1940-1980

We present the first nation wide value of life estimates for the United States at more than one point in time. Our estimates are for every ten years between 1940 and 1980, a period when declines in fatal accident rates were historically unprecedented. Our estimated elasticity of value of life with respect to per capita GNP is 1.5 to 1.7. We illustrate the importance of rising value of life for policy evaluation by examining the benefits of improved longevity since 1900, showing that the current marginal increase in longevity is more valuable than the large increase in the first half of the twentieth century.

Cowards and Heroes: Group Loyalty in the American Civil War

What motivated men to risk death in the most horrific war in U.S. history when pay was low and irregular and military punishment strategies were weak? In such a situation creating group loyalty by promoting social capital is of paramount importance and in the Civil War was the cement of both armies. We find that individual and company socio-economic and demographic characteristics, ideology, and morale were important predictors of group loyalty in the Union Army. Company characteristics were more important than ideology or morale. Soldiers in companies that were more homogeneous in ethnicity, occupation, and age were less likely to shirk.

Understanding the Decline in Social Capital, 1952-1998

We evaluate trends in social capital since 1952 and assess explanations for the observed declines. We examine both social capital centered in the community and in the home and argue that the decline in social capital has been over-stated. Controlling for education, there have been small declines in the probability of volunteering, larger declines in group membership, and still larger declines in the probability of entertaining since the 1970s. There have been no declines in the probability of spending frequent evenings with friends or relatives, but there have been decreases in daily visits with friends or relatives. Rising community heterogeneity (particularly income inequality) explains the fall in social capital produced outside the home whereas the rise in women's labor force participation rates explains the decline in social capital produced within the home.

Forging a New Identity: The Costs and Benefits of Diversity in Civil War Combat Units for Black Slaves and Freemen

By the end of the Civil War, 186,017 black men had fought for the Union Army and roughly three-quarters of these men were former slaves. Because most of the black soldiers who served were illiterate farm workers, the war exposed them to a much broader world. The war experience of these men depended upon their peers, their commanding officers, and where their regiment toured. These factors affected the later life outcomes of black slaves and freemen. This paper documents both the short run costs and long run benefits of participating in a diverse environment. In the short run the combat unit benefited from company homogeneity as this built social capital and minimized shirking, but in the long run men's human capital and aquisition of information was best served by fighting in heterogeneous companies.

Outcome assessment after hip fracture : is EQ-5D the answer?

Objectives: To study the measurement properties of a joint specific patient reported outcome measure, a measure of capability and a general health-related quality of life (HRQOL) tool in a large cohort of patients with a hip fracture. Methods: Responsiveness and associations between the Oxford Hip Score (a hip specific measure: OHS), ICEpop CAPability (a measure of capability in older people: ICECAP-O) and EuroQol EQ-5D (general health-related quality of life measure: EQ-5D) were assessed using data available from two large prospective studies. The three outcome measures were assessed concurrently at a number of fixed follow-up time-points in a consecutive sequence of patients, allowing direct assessment of change from baseline, inter-measure associations and validity using a range of statistical methods. Results: ICECAP-O was not responsive to change. EQ-5D was responsive to change from baseline, with an estimated standardised effect size for the two datasets of 0.676 and 0.644 at six weeks and four weeks respectively; this was almost as responsive to change as OHS (1.14 at four weeks). EQ-5D correlated strongly with OHS; Pearson correlation coefficients were 0.74, 0.77 and 0.70 at baseline, four weeks and four months. EQ-5D is a moderately good predictor of death at 12 months following hip fracture. Furthermore, EQ-5D reported by proxies (relatives and carers) behaves similarly to self-reported scores. Conclusions: Our findings suggest that a general HRQOL tool such as EQ-5D could be used to measure outcome for patients recovering from hip fracture, including those with cognitive impairment

Warwick hip trauma study : a randomised clinical trial comparing interventions to improve outcomes in internally fixed intracapsular fractures of the proximal femur : protocol for The WHiT Study

Background Controversy exists regarding the optimal treatment for patients with displaced intracapsular fractures of the proximal femur. The recognised treatment alternatives are arthroplasty and internal fixation. The principal criticism of internal fixation is the high rate of non-union; up to 30% of patients will have a failure of the fixation leading to revision surgery. We believe that improved fracture healing may lead to a decreased rate of failure of fixation. We therefore propose to investigate strategies to both accelerate fracture healing and improve fixation that may significantly improve outcomes after internal fixation of intracapsular femoral fractures. We aim to test the clinical effectiveness of the osteoinductive agent platelet rich plasma and conduct a pilot study of a novel fixed-angle fixation system. Design We have planned a three arm, single centre, standard-of-care controlled, double blinded, pragmatic, randomised clinical trial. The trial will include a standard two-way comparison between platelet-rich plasma and standard-of-care fixation versus standard-of-care fixation alone. In addition there will be a subsidiary pilot arm testing a fixed-angle screw and plate fixation system

An evaluation of the quality of statistical design and analysis of published medical research : results from a systematic survey of general orthopaedic journals

Background: The application of statistics in reported research in trauma and orthopaedic surgery has become ever more important and complex. Despite the extensive use of statistical analysis, it is still a subject which is often not conceptually well understood, resulting in clear methodological flaws and inadequate reporting in many papers. Methods: A detailed statistical survey sampled 100 representative orthopaedic papers using a validated questionnaire that assessed the quality of the trial design and statistical analysis methods. Results: The survey found evidence of failings in study design, statistical methodology and presentation of the results. Overall, in 17% (95% confidence interval; 10–26%) of the studies investigated the conclusions were not clearly justified by the results, in 39% (30–49%) of studies a different analysis should have been undertaken and in 17% (10–26%) a different analysis could have made a difference to the overall conclusions. Conclusion: It is only by an improved dialogue between statistician, clinician, reviewer and journal editor that the failings in design methodology and analysis highlighted by this survey can be addressed

A randomised controlled trial of total hip arthroplasty versus resurfacing arthroplasty in the treatment of young patients with arthritis of the hip joint

Background: Hip replacement (arthroplasty) surgery is a highly successful treatment for patients with severe symptomatic arthritis of the hip joint. For older patients, several designs of Total Hip Arthroplasty have shown excellent results in terms of both function and value for money. However, in younger more active patients, there is approximately a 50% failure rate at 25 years for traditional implants. Hip resurfacing is a relatively new arthroplasty technique. In a recent review of the literature on resurfacing arthroplasty it was concluded that the short-term functional results appear promising but some potential early disadvantages were identified, including the risk of femoral neck fracture and collapse of the head of the femur. The aim of the current study is to assess whether there is a difference in functional hip scores at one year post-operation between Total Hip Arthroplasty and Resurfacing Arthroplasty. Secondary aims include assessment of complication rates for both procedures as well cost effectiveness. Methods/design: All patients medically fit for surgery and deemed suitable for a resurfacing arthroplasty are eligible to take part in this study. A randomisation sequence will be produced and administered independently. After consenting, all patients will be clinically reviewed and hip function, quality of life and physical activity level will be assessed through questionnaires. The allocated surgery will then be performed with the preferred technique of the surgeon. Six weeks post-operation hip function will be assessed and complications recorded. Three, six and 12 months post-operation hip function, quality of life and physical activity level will be assessed. Additional information about patients' out-of-pocket expenses will also be collected
