Studies of the “delegated state” highlight the growing role of nongovernmental organizations to fulfill public purposes. We argue that America’s delegated state has taken two distinct forms: a civic-public model prominent in the North and Midwest and a very different religious-private model more evident in the South and the West. Distinctive regional legacies rooted in European immigration, religion, race, and the timing of urban growth gave rise to diverse organizational configurations for assisting the poor in different parts of the country. As a consequence, the institutions for assisting the poor are weaker in the growing regions of the South and Mountain West.

Whether as a solution to problems of political legitimacy or social mistrust, as a way of involving civil society, or as a method of crafting more effective “third way” policies, collaborative governance has been a topic of renewed interest for political scientists and policy intellectuals. Carmen Sirianni's Investing in Democracy: Engaging Citizens in Collaborative Governance (Brookings, 2009) is an important new book that raises many of these issues. Perspectives on Politics is a forum for raising questions of interest to a broad range of political scientists. In this symposium, we have asked a number of prominent political scientists and policy analysts to assess the book and to address two broader questions: in what ways does the book draw from and add to political science scholarship, and in what ways does political science scholarship help to shed light on the book's core themes?

An experiment to measure the variation in the phenological and apical development ofwinter wheat (cv. Avalon) in England and Scotland is described. Ten sites which ranged from Aberdeen (57·2° N), the most northerly, to Newton Abbot (50·6° N), the most southerly, were included in the survey, and at each site seed was hand-sown in mid-September, October and November 1983. Developmental stages and sampling procedures were precisely defined to ensure uniformity in scoring by the observers at each site. Temperatures during the growing season were in line with the long-term means, though spring was cooler at all sites and summer warmer at most. The range of monthly-mean temperatures between sites was about the same as the difference between consecutive months. The method of analysis of development rates and durations was in terms of thermal time, modified by sensitivity to photoperiod and a vernalization requirement that slowed early development until a number of days of low temperatures had been experienced. In general, crops at northern sites developed more slowly than those in the south and particularly the south-west of England. There was less variation in the timing of apical stages for later sowings. Developmental rates responded linearly to temperature and photoperiod, with the base temperature increasing for later phases of development. The effect of photoperiod in modifying the rate of development was apparent for all developmental phases from emergence to anthesis, longer days accelerating development, but there was no effect on the duration of the grain-filling period. Vernalization exerted its effect solely within the phase from emergence to double ridge, and had a major influence on the variation between sites only for the first sowing.

The initiation of leaf and spikelet primordia was studied at sites ranging in latitude from Newton Abbot (50·6°N) to Aberdeen (57·2°N) in crops sown in the middle of September, October and November 1983. The rate of primordium initiation tended to decrease from south to north but there were also marked differences between quite close sites.

The rate of leaf initiation increased with temperature but photoperiod had little effect; the rate of spikelet initiation was affected both by temperature and by photoperiod. There were differences in the total number of leaves initiated which were only partlyexplained by differences in vernalization.

Expressing leaf and spikelet initiation rates in terms of thermal and photo-thermal time respectively showed a constant rate of leaf initiation and a constant and more rapid rate of spikelet initiation.
