ABSTRACT This paper uses a stochastic frontier production-function model to measure and compare productivity efficiency in the manufacturing sector of states in the United States over the period 1959–1972. Based on this model we find considerable variations in productive efficiency across states. A large portion of the variation is found to be related to regional differences in labor-force characteristics, levels of urbanization and industrial structure. We also examine the relationship between productive efficiency and the subsequent growth of manufacturing and find some evidence of a weak relationship between efficiency and the growth of employment. 相似文献

Use of particular lithic quarries by different cultural groups is a prominent feature of the Pastoral Neolithic period in southern Kenya (ca. 3200–1400 b.p.), when lifeways based on herding domesticated livestock spread through eastern Africa. Here, I present lithic attributes from the recently excavated Elmenteitan Obsidian Quarry assemblage to examine the site’s role in an obsidian distribution network spanning southwestern Kenya. Evidence from the quarry reflects intensive preparation of blade cores and blade reduction. Changes in platform size, flake scar orientation, curvature, and cortical rates through the reduction sequence permit a preliminary reconstruction of Elmenteitan core production strategies that can serve as a basis for regional comparative studies. Uniformity in blade core design and reduction strategy suggests highly organized use of the quarry and supports its role as a production center for regional exchange. Results inform regional debates and contribute to a growing literature on the potential of quarry archaeology. 相似文献

Henry Tudor’s diffusion of power in the English far north, and his savage pruning of resources for his wardens there to maintain good rule and defence, were perhaps necessary steps initially to prevent further challenges from overmighty subjects. Twenty years later, this was no longer an issue; and once peace with Scotland collapsed, the absence of the region’s traditional ruling magnates was keenly felt. Under Henry VIII, an obscure border baron, Lord Ogle of Bothal, was often Northumberland’s only resident lord, precipitating a crisis of lordship described as ‘the decay of the borders’. Unable to recruit as warden a reliable magnate on acceptable terms, Henry VIII then decided that, as a matter of principle, he would ‘not be bound, of a necessity, to be served there with lords’. The King appointed himself as warden-general, delegating the real work to gentlemen deputy wardens whose manraed was enhanced by feeing other leading local landowners, including Lord Ogle. Ogle’s kin and connection thus supplied successive wardens with an adequate following in peacetime; but in the ensuing war Ogle was overwhelmed with his warden on Ancrum Moor, becoming the only nobleman in England under Henry VIII to die in battle. 相似文献

Although both of the categories of nationality and religion are difficult to define, it is nonetheless necessary to do so. Having done so, one can proceed with clarifying what is distinctive of each of them, and, thus, be in a position to ascertain their points of convergence and difference. Evaluation of the contribution of Anthony Smith to our understanding of the relation between nationality and religion is the point of departure for a re‐examination of the relation. 相似文献

This paper attempts to further the research by Odland and Ellis (1992) in applying event history methodology to the analysis of spatial point patterns (that is, event patterns). Its empirical focus is the event pattern derived from the adoption of an agricultural innovation, the Harvestore, in southern Ontario, Canada, from 1963 to 1986. Event history analysis involves the use of discrete-state, continuous-time stochastic models to investigate a temporal longitudinal record on discrete variables. Event history models are usually concerned with durations of time between events and the effects of intertemporal time dependencies on future event occurrences. As such, they are often referred to as duration models. Many of the methods used in event history analysis allow the use of other nonnegative interval measurements in place of standard temporal intervals to investigate a series of events. In particular, spatial intervals (or durations) of distances between events may also be accommodated by event history models. Our analysis extends the previous research of Odland and Ellis (1992) by using a wider range of parametric models to explore duration dependence, investigating the role of spatial censoring, and using a more extensive set of explanatory variables. In addition, simulation experiments and graphical tests are used to evaluate the empirical event pattern against one generated from Complete Spatial Randomness. Results indicate that the event pattern formed by the Harvestore adopter farms is clustered (that is, is described by positive duration dependency), the sales agent is a significant factor in the distribution of adopters, and that contrasting results are obtained from the analysis using censored data versus uncensored data. 相似文献

This study looks in depth at three family policy issues surrounding one state's attempt to recover costs for child support enforcement services provided to nonpublic assistance families. The issues are whether a cost recovery user fee should be assessed; to whom the fee should be assessed; and how to develop a fee structure to meet criteria established by the policy agents. The original study was mandated by the state legislature. Recommendations were made to the legislature to continue one small fee, discontinue another unpopular fee, and institute three new broad-based fees that would allow for nearly full cost recovery. In an election year the legislature accepted the first two recommendations but chose not to pursue the three new fees. Implications for policy development are drawn, focusing on the impact of user fees on service recipients and the role of the public sector in providing services that are available in the private sector in an era of tighter budgets. 相似文献
