Plants are technologies

Histories of Technology, the Environment and Modern Britain brings together historians with a wide range of interests to take a uniquely wide-lens view of how technology and the environment have been intimately and irreversibly entangled in Britain over the last 300 years. It combines, for the first time, two perspectives with much to say about Britain since the industrial revolution: the history of technology and environmental history. Technologies are modified environments, just as nature is to varying extents engineered. Furthermore, technologies and our living and non-living environment are both predominant material forms of organisation – and self-organisation – that surround and make us. Both have changed over time, in intersecting ways. Technologies discussed in the collection include bulldozers, submarine cables, automobiles, flood barriers, medical devices, museum displays and biotechnologies. Environments investigated include bogs, cities, farms, places of natural beauty and pollution, land and sea. The book explores this diversity but also offers an integrated framework for understanding these intersections

Work and Older Persons in Rural Iowa

Once a state abundant with children and youth, Iowa is now tied with Florida as having the largest population segment in the 65 and older category. Why has the change occurred? Where do these people live? Are they still active in work? This article, the first in a series on Iowa\u27s changing population, explores these questions

Money and the Mature Worker in Iowa

Finances often determine whether or not an older man will continue to work. This article takes a look at the assets and incomes of Iowa\u27s older workers and how it affects their employment

Social Activities of Older Workers

Some say that people socialize less as they get older. The authors of this article have a look at whether Iowa\u27s older workers follow this pattern

Indigenous Australians and competition and consumer issues: A review of the literature and an annotated bibliography

This working paper is based on a literature search conducted to identify and review relevant Australian and overseas research that is of relevance to Indigenous competition and consumer protection matters. The focus of the literature search has been on matters of relevance to Indigenous communities throughout Australia related to the Trade Practices Act 1974 (TPA). Results of the literature search suggest that most research conducted to date has focused on issues associated with Indigenous community stores and consumer banking. In addition, the geographic focus of past research has been predominantly on remote and regional Australia, areas where the structural impediments associated with remoteness may impede competition. Further, although the research has included some discussion of competition in Indigenous communities, it has mainly focused on consumer issues

Influence of Beginning Body Condition Scores on Net Returns From Feeding Cull Cows

The impact of beginning body condition scores on returns from feeding cull cows was investigated in a two year experiment. In each of two culling years, physical performance data and financial data were measured at approximately monthly intervals for culls on pasture versus dry lot. Specifically, data was collected for cows culled in October 2007 and held through April 2008 and for cows culled in October 2008 and held through March 2009. We examine the sensitivity of net returns relative to the choice of body condition score as a sorting trigger for heavy versus thin cows. In this two year study, while a pasture system was generally more profitable than a drylot system, thin cows were typically more profitable than cows with higher BCS, regardless of the feeding system. The importance of the sorting criteria is highlighted in year two. Using the lower BCS criteria for sorting is the only scenario that generates positive net returns, albeit small. Thus, decisions regarding cull cow retention and feeding should consider body condition scores.Agricultural and Food Policy,
