All in the Family

The authors look at how family income depends on family structure. Using data from the 1973, 1979, and 1987, Current Population Survey, the authors examine four income sources (earnings, property, child support, and government transfers) among seven family types for all families and for Latino, black, and white householder families. The authors find large income differences among families–primarily due to differences in earnings–but little change within family types over time. Increasing the work hours of adult members or relying on income support from nonresident family members is unlikely to substantially remedy the differences in income among family types, and specifically to improve the very low income of single-mother families. Other family policies are suggested.     

Tracks Across the Irwell: From the Liverpool & Manchester Railway to the Ordsall Chord

ABSTRACT

Archaeological excavations and built heritage recording has been undertaken by Salford Archaeology (based within the Centre for Applied Archaeology, University of Salford) during the construction of a new rail link across the River Irwell between Manchester and Salford, known as the ‘Ordsall Chord’. The new bridge links existing lines of historic importance, and also crosses the extant remains of the world’s first passenger steam railway, the Liverpool & Manchester Railway, being carried over the Grade I designated ‘Stephenson's Bridge’ at approximately deck level. Six further Grade II designated structures were also affected by the scheme, as were the below-ground remains of a dye works that predated the opening of the railway in the 1830s, and a large livestock market that grew adjacent to the improved transport infrastructure provided by the rail network. This paper discusses the archaeological work undertaken on this important early transport hub during the construction programme in 2015–18.     

Geographically Weighted Regression: A Method for Exploring Spatial Nonstationarity

Spatial nonstationarity is a condition in which a simple “global” model cannot explain the relationships between some sets of variables. The nature of the model must alter over space to reflect the structure within the data. In this paper, a technique is developed, termed geographically weighted regression, which attempts to capture this variation by calibrating a multiple regression model which allows different relationships to exist at different points in space. This technique is loosely based on kernel regression. The method itself is introduced and related issues such as the choice of a spatial weighting function are discussed. Following this, a series of related statistical tests are considered which can be described generally as tests for spatial nonstationarity. Using Monte Carlo methods, techniques are proposed for investigating the null hypothesis that the data may be described by a global model rather than a non-stationary one and also for testing whether individual regression coefficients are stable over geographic space. These techniques are demonstrated on a data set from the 1991 U.K. census relating car ownership rates to social class and male unemployment. The paper concludes by discussing ways in which the technique can be extended.
