J. L. Pilliard 《R&D Management》1977,7(S1):157-163
M. Pilliard explained that he was not speaking as an academic, a researcher, a sociologist or a futurologist, but as an industrialist From this starting point he was concerned with broadening the idea of product and extending the role of demand in the search for innovation. He was also concerned with the way in which the different stages of R & D evolution related to the growing interdependence of business with its environment 相似文献

A review of the literature on the empirical effects of advance notification of plant closings (voluntary and mandated), including the authors' recent study using data drawn from the 1984 Survey of Displaced Workers. suggests that advance notice reduces the probalility that displaced workers suffer any spells of unemployment and may also moderated temporary increases in area unemployment rates. There is little evidence of adverse effects of advance notice, either to workers or to firms. The implications for public policy are discussed. 相似文献

The long-term value proposition of transportation infrastructure investments can be significantly distorted if the short-term effects of spatial externalities on land use patterns, economic expansions, and migration patterns are not properly included in the analysis. Some of these effects occur over a short period of time and soon after the investment materializes, whereas others take longer and follow more steady patterns. In this article, we develop a novel dynamical model of a primal society with constructs that are specifically geared toward transportation infrastructure expansions and investments. The model quantifies the impact of these expansions on some key performance indicators and on the overall utility and production capacity of the society. We argue that traditional analytical models that work on the premises of stationary behavior and a static response of society to changes in infrastructure do not correctly capture these effects. The land use patterns and spatial expansion computed from the model are validated against existing theory on land use. Preliminary results on how to use the model for value proposition analysis are also presented using simple case studies. 相似文献

《Telecommunications Policy》2007,31(6-7):359-373
Even as geographic disparities in high speed Internet access narrow, an urban–rural broadband gap persists, pointing to the importance of individual differences in motivations to adopt broadband as the key to closing the gap. Diffusion of innovation is reconceptualized through contemporary perspectives of the digital divide and social cognitive theory and tested on a survey sample drawn from four rural communities. Path analysis was used to examine the factors that cause broadband Internet service adoption in rural communities. Prior experience with the Internet, the expected outcomes of broadband usage, direct personal experience with broadband, and self-efficacy had direct effects on broadband intentions. Age and income, but not education or ethnicity, also had direct impacts. Efforts that promote the personal benefits of broadband and advanced ICT literacy skills among Internet users are recommended. 相似文献

A persistent challenge for telecommunications policy is the determination of broadband provision footprints in both space and time. In the United States, Form 477 data from the Federal Communications Commission (FCC) provide a valuable snapshot of broadband provision at the block level, but there are often inconsistencies with the underlying data. These inconsistencies include overly-optimistic self-reports from providers, requirements to report broadband provision within inflexible census administrative units, and a modest temporal reporting schedule (biannual) with a significant, one year temporal lag. These uncertainties are often compounded by telecommunications providers refusing to disclose any information on service footprints, geographic expansion plans or the characteristics of populations served by broadband. This type of obfuscation drastically limits the ability of policy analysts to evaluate outcomes (both positive and negative) associated with service provision and the digital divide, more generally. With the recent entry of Google Fiber to several metropolitan markets in the United States, many of the broadband reporting and evaluation challenges have re-emerged. The purpose of this paper is to leverage basic data mining techniques, a scale agnostic geographic framework and exploratory spatial data analysis (ESDA), to uncover the geographic intricacies of Google Fiber (Fiber) service for both Provo, Utah and Austin, Texas and compare them to Form 477 reports. In addition, we use basic statistical approaches to explore issues of broadband access and equity, accounting for the differences in socio-economic and demographic status of the populace served/not served for both cities, as well as basic pricing within and between communities. 相似文献

实施关闭破产的有关问题及政策--国家煤炭工业局副局长王君谈"14.40"工程 总被引:1,自引:0,他引:1
一、实施关闭破产是煤炭企业扭亏脱困的重要举措 实现党的十五大提出的三年改革脱困目标,是全党的重要任务,也是煤炭行业重大而艰巨的任务.当前,煤炭行业比较困难,市场供大于求,价格持续下滑,货款拖欠猛增,亏损大幅度上升.造成这种局面的深层次原因,是煤炭工业的结构不合理. 相似文献
