This volume develops the major themes of time series analysis from its formal beginnings in the early part of the 20th century to the present day through the research of six distinguished British statisticians, all of whose work is characterised by the British traits of pragmatism and the desire to solve practical problems of importance.

Covers the key issues required for students wishing to understand and analyse the core empirical issues in economics. It focuses on descriptive statistics, probability concepts and basic econometric techniques and has an accompanying website that contains all the data used in the examples and provides exercises for undertaking original research.

Today, black-owned barber shops play a central role in African American public life. The intimacy of commercial grooming encourages both confidentiality and camaraderie, which make the barber shop an important gathering place for African American men to talk freely. But for many years preceding and even after the Civil War, black barbers endured a measure of social stigma for perpetuating inequality: though the profession offered economic mobility to black entrepreneurs, black barbers were obliged by custom to serve an exclusively white clientele. Quincy T. Mills traces the lineage from these nineteenth-century barbers to the bustling enterprises of today, demonstrating that the livelihood offered by the service economy was crucial to the development of a black commercial sphere and the barber shop as a democratic social space. Cutting Along the Color Line chronicles the cultural history of black barber shops as businesses and civic institutions. Through several generations of barbers, Mills examines the transition from slavery to freedom in the nineteenth century, the early twentieth-century expansion of black consumerism, and the challenges of professionalization, licensing laws, and competition from white barbers. He finds that the profession played a significant though complicated role in twentieth-century racial politics: while the services of shaving and grooming were instrumental in the creation of socially acceptable black masculinity, barbering permitted the financial independence to maintain public spaces that fostered civil rights politics. This sweeping, engaging history of an iconic cultural establishment shows that black entrepreneurship was intimately linked to the struggle for equality.

Modelling trends and cycles in economic time series has a long history, with the use of linear trends and moving averages forming the basic tool kit of economists until the 1970s. Several developments in econometrics then led to an overhaul of the techniques used to extract trends and cycles from time series. Terence Mills introduces these various approaches to allow students and researchers to appreciate the variety of techniques and the considerations that underpin their choice for modelling trends and cycles.

Growth curves are used to model various processes, and are often seen in biological and agricultural studies. Underlying assumptions of many studies are that the process may be sampled forever, and that samples are statistically independent. We instead consider the case where sampling occurs in a finite domain, so that increased sampling forces samples closer together, and also assume a distance-based covariance function. We first prove that, under certain conditions, the mean parameter of a fixed-mean model cannot be estimated within a finite domain. We then numerically consider more complex growth curves, examining sample sizes, sample spacing, and quality of parameter estimates, and close with recommendations to practitioners.

The LP recourse problem applies to two-stage optimization problems where uncertainty in resource availability of the second stage hinders informed decision making. The recourse function affords a way to compensate "later" for an error in prediction "now." The literature provides a rich body of work on the optimization of such problems, but little research has been accomplished regarding the characterization of the surface in the local region of optimality, in particular sensitivity analysis. A decision maker faced with considerations other than the modeled objective function must be presented with a way to estimate the impact of operating at non-optimal decision variable values. This work develops and demonstrates a technique for characterizing the surface using response surface methodology. Specifically, the flexibility and utility of RSM techniques applied to this class of problems is demonstrated, and a methodology for characterizing the surface in the local region using a low-order polynomial is developed.

United States Transportation Command serves as the source for transportation needs within the Department of Defense. During hurricanes Katrina, Gustav and Ike contracted commercial passenger aircraft were used almost exclusively to evacuate general population members from the coastal regions of Texas and Louisiana. Senior leadership requested a further analysis regarding the use of military aircraft in support of general population evacuation preceding hurricanes. Collection of data from previous hurricane evacuations and interviews of senior leaders and planners in various agencies allowed for a comparison in selection of military versus commercial assets. By analyzing both cost and non-cost factors in a course of action analysis the best mix of resources can be posited. It was determined that military aircraft should be used in conjunction with contracted commercial carriers in order to execute the most effective evacuation of general population personnel prior to hurricane landfall in the gulf region of Texas and Louisiana. Research revealed that further research is necessary regarding cueing of passengers from various communities and during late night hours.
