The transition from an industrial economy to an innovation economy poses two critical questions for the manufacturing sector in advanced countries. First, given the diffusion of modern manufacturing practices around the world, what level of innovation (incremental, more far-ranging, or radical) is most likely to support a resilient domestic manufacturing sector? Second, are assumed differences in the innovative capacity across space likely to hasten the decline of rural manufacturing? To answer these questions this research combines comprehensive measures of self-reported innovation able to reliably differentiate incremental and more far-ranging innovation with establishment-level data able to examine the geographical distribution of these different innovation strategies. The data used for the analysis includes a two-period panel of manufacturing establishments surveyed in 1996 and 2013 with annual employment data indicating survival in the intervening years. Our findings suggest that long-surviving manufacturing plants overwhelmingly gravitate away from non-innovation strategies toward incremental or more far-ranging innovation orientations. A survival advantage of far-ranging innovation over incremental innovation is observed for standalone firms. We do not identify a difference in the innovation orientations of rural and urban manufacturing establishments. 相似文献

This article continues the analyses of the impact of an innovative teacher education programme aimed at school improvement in a developing country context (A. Khamis, P. Sammons, 2004. The development of a cadre of teacher educators: some lessons from Pakistan. International Journal of Educational Development, 24(3), 255–268). Building on recent publications that have analysed outcomes of the teacher education programme and how the cadre of teacher educators has worked to initiate improvement in schools in Pakistan. The article considers the ‘teacher education for school improvement model’ based on findings from the case studies of nine co-operating school. Lessons are presented to further inform the development of teacher education programmes and the measurement of effectiveness of such programmes in developing country contexts. The article further considers relevant international research on educational change and reform to draw further lessons. These lessons include the need to pay greater attention to the cultural contexts and milieu in Pakistan, and the need to create models of school improvement and teacher education that originate within developing country contexts rather than the adaptation of European/North American models that are based on sources of data in those contexts. The article concludes by arguing for the need to develop better theoretical understandings from the current innovations underway and placing the onus on intervening agencies to better inform educational change strategies promoted in developing country contexts. 相似文献

Nikola Tesla was one of the greatest inventors of all times. He can be placed along with Faraday and Edison as a prolific
inventor who touched on almost every aspect of electricity. In fact he invented electricity as we know it today and hence
ushered in the modern age.
Anil K Rajvanshi is a mechanical engineer by profession. He was educated in IIT Kanpur and did his PhD from the University
of Florida, Gainesville, in 1979. He has more than 25 years of experience in rural development and runs a rural NGO called
Nimbkar Agricultural Research Institute in Maharashtra. Besides his technological work he also has interests in issues of
technology and spirituality and writes extensively on this subject. 相似文献

The categorization performance of monkeys on a unidimensional perceptual categorization task was examined with reference to
decision bound and exemplar theories of categorization. Three rhesus monkeys were presented with stimuli varying along a single
dimension, the displacement of a target light from a fixation point. Left or right saccade responses were probabilistically
reinforced according to one of three functions, two of which were nonmonotonic at one end of the stimulus space. The monkeys
all showed a monotonic increase in response probability as a function of target light displacement in this region, consistent
with decision bound theory. Fits of a single-boundary model (GRT; Ashby & Gott, 1988) and two exemplar models—one using a
probabilistic response function (GCM; Nosofsky, 1986), the other using a deterministic response function (DEM; Ashby & Maddox,
1993)—revealed overall support for the decision bound model. The results suggest that monkeys used a perceptual decision boundary
to perform the task. 相似文献

Most techniques in statistics are used in many disciplines besides ecology and have a wide range of applications from anthropology to zoology. They are used in industry, agriculture, social sciences and business. That is why we have called this series ’Numeracy for Everyone’. In the forthcoming parts, we will discuss applications of statistics in some of these fields. But some techniques are developed specially for ecological problems. Let us briefly look at a selection of those techniques. 相似文献

Sickle cell disease is known to cause acute pancreatitis either due to gall stones obstructing the pancreatic duct or by vaso-occlusive mechanism. However chronic pancreatitis is a very rare complication in sickle cell anemia. We report a case of sickle cell trait presenting with chronic pancreatitis with pseudo cyst. USG abdomen and CT abdomen confirmed the diagnosis of chronic calcific pancreatitis with pseudocyst. Etiological work up for other causes did not reveal anything except sickle cell trait. This case represents a rare association between chronic calcific pancreatitis and sickle cell trait. 相似文献

Providing government information, services, products and transactions electronically has the potential benefit of accessibility for a wider audience, political and administrative transparency, and improved service delivery. By using e-government websites, citizens can conveniently access government information and services and gain greater opportunities to participate in democratic processes. The present study aims to evaluate National Portal of India, which provides single window access to 601 e-government portals and websites in India. A total of 1576 online services are provided by these portals responding to information needs of the citizens. Ranking of the state and union territory portals has been done based on the number of online services they provide. The paper also focuses on the digitization of documents, acts, rules and schemes of central and state government departments and their availability and accessibility through government portals. 相似文献
