Quan D. Mai 《Labor History》2016,57(2):141-169
The period that spanned the Gilded Age to the onset of the Great Depression saw the rise and relative decline of the US labor movement. The salient events of labor movements over these years undoubtedly shaped public perception about labor issues, and some scholars have been attempting to unpack the mechanisms through which depictions and characterizations of the ‘labor problem’ were produced in authoritative venues that could have shaped the future of the movement. This study goes beyond the standard practice of explaining news report volume to feature the political valance of the reports on the labor problem over a 63-year time period. The aforementioned period also saw significant changes in news reporting practices, with the rise of objective informational writing and the embrace of journalism as a profession. The change within journalism itself could potentially shape the depiction of the labor problem, yet such change has been overlooked by existing literature pertaining to the topic. This research makes a theoretical case for integrating social processes central to the labor movement and journalism from 1870 to 1932 and explains patterns in the cultural production of the labor problem in the New York Times by analyzing these two tracks of history in conjunction using both qualitative and quantitative data. 相似文献

Local government policymakers across the developed world have frequently employed municipal amalgamation to improve the operation of local councils, and New Zealand is no exception. This paper empirically examines claims made in Potential Costs and Savings of Local Government Reform in Hawke’s Bay that the merger of the five local authorities in the Hawke’s Bay Region of New Zealand would generate significant cost-savings. We empirically test for the existence of scale economies in a single merged Hawke’s Bay council and find that no cost-savings can be expected. This removes a key argument for a forced Hawke’s Bay amalgamation. 相似文献

In 2007, the Queensland Government imposed forced amalgamation with the number of local authorities falling from 157 to just 73 councils. Amalgamation was based inter alia on the assumption that increased economies of scale would generate savings. This paper empirically examines pre- and post-amalgamation (2006/07 and 2009/10) for scale economies. For the 2006/07 data, evidence of economies of scale was found for councils with populations up to 98,000, and thereafter diseconomies of scale. Eight percent of councils in 2006/07 (ten councils) – representing 64% of the state’s population – exhibited diseconomies of scale. For the 2009/10 data, the average cost curve remained almost stationary at 99,000 residents per council, but almost 25% of all councils (thirteen councils) were now found to exhibit diseconomies of scale. The compulsory merger program thus increased the proportion of Queensland residents in councils operating with diseconomies of scale to 84%. 相似文献
