Estimating Nonresponse Bias in Mail Surveys

Valid predictions for the direction of nonresponse bias were obtained from subjective estimates and extrapolations in an analysis of mail survey data from published studies. For estimates of the magnitude of bias, the use of extrapolations led to substantial improvements over a strategy of not using extrapolations

Interactions between adult migratory striped bass (Morone saxatilis) and their prey during winter off the Virginia and North Carolina Atlantic coast from 1994 through 2007

The migratory population of striped bass (Morone saxatilis) (>400 mm total length[TL]) spends winter in the Atlantic Ocean off the Virginia and North Carolina coasts of the United States. Information on trophic dynamics for these large adults during winter is limited. Feeding habits and prey were described from stomach contents of 1154 striped bass ranging from 373 to 1250 mm TL, collected from trawls during winters of 1994-96, 2000, and 2002-03, and from the recreational fishery during 2005-07. Nineteen prey species were present in the diet. Overall, Atlantic menhaden (Brevoortia tyrannus) and bay anchovy (Anchoa mitchilli) dominated the diet by boimass (67.9%) and numerically (68.6%). The percent biomass of Atlantic menhaden during 1994-2003 to 87.0% during 2005-07. Demersal fish species such as Atlantic croaker (Micropogonias undulatus) and spot (Leiostomus xanthurus) represented <15% of the diet biomass, whereas alosines (Alosa spp.) were rarely observed. Invertebrates were least important, contributing <1.0% by biomass and numerically. Striped bass are capable of feeding on a wide range of prey sizes (2% to 43% of their total length). This study outlines the importance of clupeoid fishes to striped bass winter production and also shows that predation may be exerting pressure on one of their dominant prey, the Atlantic menhaden

Working with Students and External Constituents to Revitalize an Undergraduate Degree Program

Offering undergraduate programs which are relevant and provide students excellent opportunities for employment or graduate work are key for program success and program growth. The session will describe our approach to revitalizing an unpopular undergraduate degree program based on student input and collaboration with industry and a community college

British economic growth : 1270 - 1870

We provide annual estimates of GDP for England between 1270 and 1700 and for Great Britain between 1700 and 1870, constructed from the output side. The GDP data are combined with population estimates to calculate GDP per capita. We find English per capita income growth of 0.20 per cent per annum between 1270 and 1700, although growth was episodic, with the strongest growth during the Black Death crisis of the fourteenth century and in the second half of the seventeenth century. For the period 1700-1870, we find British per capita income growth of 0.48 per cent, broadly in line with the widely accepted Crafts/Harley estimates. This modest trend growth in per capita income since 1270 suggests that, working back from the present, living standards in the late medieval period were well above “bare bones subsistence”. This can be reconciled with modest levels of kilocalorie consumption per head because of the very large share of pastoral production in agriculture

English economic growth, 1270-1700

We provide annual estimates of GDP for England over the period 1270-1700, constructed from the output side. The GDP data are combined with population estimates to calculate GDP per capita. Sectoral price data and estimates of nominal GDP are also provided. We find per capita income growth of 0.20 per cent per annum, although growth was episodic, with the strongest growth after the Black Death and in the second half of the seventeenth century. Living standards in the late medieval period were well above “bare bones subsistence”, although levels of kilocalorie consumption per head were modest because of the very large share of pastoral production in agriculture

Extractive industries as sites of supernormal profits and supernormal patriarchy?

This article considers how patriarchal power relations between men and women are produced and reproduced within extractive industries, and examines the idea that the ‘supernormal profits’ to be made there encourage the development of ‘supernormal patriarchy’. By looking at the sites where extraction takes place and relationships between men and women within these sites, we show the extreme and exaggerated gender roles and relations that are found here. We nuance this account by highlighting the need to recognise that patriarchal power is not felt equally by all women and men. Exploring the different roles women adopt in the extractives context we demonstrate the fluidity of women’s identities as workers, ‘whores’, and wives with a focus on transactional sex. The article demonstrates the importance of not seeing women merely as victims of patriarchal relations, or making assumptions about how these relations operate, or the form they take. Better understanding of the range of gender roles adopted in the extractives and the supernormal patriarchal relations that produce and reproduce these is needed by policymakers. This will enable them to promote gender equality and natural resource justice, as part of an agenda to redistribute wealth gains from natural resource extraction
