Are some American states inherently more innovative than others? This question has confounded researchers for more than four decades. In this study we develop a measure of collective policy innovation that measures formal cooperative policy arrangements among the states, compare the measure to existing measures of internal state policy innovation, and assess whether existing innovativeness measures explain policy cooperation among the states. This test of the innovativeness concept addresses internal and external validity concerns that have long plagued this research tradition. Our multivariate analyses indicate that policy innovativeness is often a statistically and substantively important determinant of compact participation. These results suggest that (i) innovativeness is a meaningful and durable state attribute, (ii) several existing indices successfully capture the underlying latent concept, and (iii) innovativeness provides analytic utility in multiple empirical contexts. 相似文献

This paper aims to describe Bruno Latour's contributions to the theory and methodology of agency in the Philosophy of Science
and to apply them to the study of agency in archaeology. These contributions include an understanding of how artifacts or
representations of the world emerge, what the best conditions to study them under are and how to understand the process of
change they undergo. A case study using the Hopewell burial mounds of the Lower Illinois Valley will serve to demonstrate
the application of this methodology. 相似文献

Globalization and neoliberalism are having significant impacts upon the cleaning industry, as in the drive for greater work “efficiency”. One way in which cleaning companies have sought to increase efficiency is through the introduction of new equipment and forms of work organization. However, such moves appear to be having negative impacts upon cleaners’ bodies, and many report significant work‐related health problems. In light of this, here we explore the bodily consequences of two possible strategies for giving cleaners a healthier workday—increasing variation within cleaners’ current work tasks or allowing them to engage in a broader range of tasks through job enlargement. Drawing upon a literature review performed as part of a recent European Union project concerning the degree of physical strain to which cleaners are exposed during cleaning, a Danish laboratory study focusing on the loads to which cleaners’ shoulder muscles, backs, and hearts were exposed by different cleaning tasks, and a field study investigating the effects of job enlargement in Danish hospitals, we show that cleaning work is characterized by repetitive work for the muscles of the body's upper extremities and by high levels of dynamic and static force upon these muscles, regardless of which modes of cleaning (old or new style of cleaning tools) are used. Equally, monitoring of heart rates and assessment of the psychosocial environment suggest that simply interchanging current cleaning tasks does not provide sufficient variation in cleaners’ work to prevent work‐related musculoskeletal or cardiovascular damage, nor to create a less mentally stressful work environment. Although introducing greater work variation through job enlargement (such as combining cleaning with kitchen and portering tasks) is often presented as an effective way to minimize musculoskeletal and cardiovascular damage, our field study shows that even this does not provide sufficient variation in physical work conditions, although improvement in some cleaners’ mental health was noted. Therefore, we conclude, prevention of musculoskeletal and cardiovascular disorders demands a much more comprehensive strategy of work redesign than that proposed by some employers and government agencies. Whether this is likely, given competitive pressures towards increased outsourcing and privatization, is, of course, the question. 相似文献

The formerly sleepy, rural county of Oxfordshire is now one of Europe's leading centres of enterprise, innovation and knowledge. It is a hotspot for high-tech manufacturing and service employment. But what is behind this phenomenon, and to what extent has it been managed? This paper sets out the facts, and explores the underlying factors. It starts with a number of definitional questions and approaches used in the research. It concludes with an examination of the role of planning in the process—and the extent to which is has helped or hindered the rise of “Enterprising Oxford”. 相似文献

This paper explores the voting patterns of trade union members in Australian elections conducted between 1966 and 2004 and finds that, on average, 63% of trade union members vote for the Australian Labor Party. Despite the fact that union membership declined from around half of the workforce in the early 1980s to a quarter of the workforce in the early 2000s, unionists have not become more pro-Labor. Analysing unionists' voting behaviour by gender, it is found that male unionists were more pro-Labor than female unionists in the 1960s, but that the reverse is true today. Recognising that union membership may be endogenous with respect to political ideology, this study instruments for union membership and concludes that the observed association between union membership and voting reflects a causal relationship. 相似文献

In 2002 Melbourne’s Casselden Place excavation provided a window into the urban past opened by an innovative relationship between the development industry, heritage consultancy and La Trobe University. The project demonstrated that with the support of consent authorities and the co-operation of the development industry, collaborations between the academic world and heritage consultants could be highly successful. The Casselden Place Project made a significant contribution to the ‘slum debate’ in Australia and delivered an enhanced understanding of the cultural, social and scientific significance of an inner-city block, and shed new light on a notorious chapter in the city’s history. 相似文献
