For estimation of grain yield in wheat, Normalized Difference Vegetation Index (NDVI) is considered as a potential screening tool. Field experiments were conducted to scrutinize the response of NDVI to yield behavior of different wheat cultivars and nitrogen fertilization at agronomic research area, University of Agriculture Faisalabad (UAF) during the two years 2008-09 and 2009-10. For recordi...

We examine how one industry’s productivity is affected by the IT capital of its customers, and how this effect depends on the industries’ relative concentration. These customer-driven IT spillovers result from customers’ IT investment in various information systems that reduce transaction costs through information sharing and coordination, leading to more efficient production and logistics upst...

Overlapping activities that are traditionally performed in a sequential manner can significantly reduce project delivery times. Overlapping, however, should be approached in a systematic manner to reduce the costs and risks. Information gathered from sector-based case studies and from the manufacturing domain suggest a formalised framework for identifying overlapping opportunities and strategie...

Agents located from downstream to upstream along an estuary and exposed to a flooding risk have to invest in facilities like a seawall (or dike). As the benefits of that local public good increase along the estuary, upstream agents have to bargain for monetary compensation with the most downstream agent in exchange for more protection effort. The paper analyses different bargaining protocols an...

Background: There is ongoing interest in assessing the effectiveness of various drug control strategies, including policy intended to reduce initiation and prevalence. Compartmental models of trajectories of drug use have been developed that demonstrate that drug “systems” display significant inertia; interventions on systems with high inertia can be difficult to evaluate. Method: The implicati...

Studies of forested rural watersheds provide estimates of background contamination for comparison with streams and rivers in other settings. We performed a landscape analysis and measured major dissolved ions and benthic macroinvertebrates for a small rural watershed in Albany County, NY, to determine spatial variation in water quality. An estimated 73% of the surface cover is postagricultural ...

In this paper, the shift into international franchising from other forms of operation, rather than the typical home market franchising base, is explored. The focus is international retail franchising, based on a study of the Danish clothing and footwear industry. In this study it was found that Danish companies were moving into international franchising as an outcome of a more general shift fro...

Firms are involved in supply chains to achieve operative efficiency, develop strategic advantages, and generate financial profits. However, there is limited evidence regarding how governance mechanisms influence the generation of value from collaboration. Furthermore, how a particular buyer or supplier position provides benefits to partners is unclear. In this paper, we examine the roles of man...

Beyond the factory floor, there is an even larger opportunity to improve performance. The true world-class competitors have discovered this opportunity and have extended the principles that worked on the factory floor to the upstream processes that feed production, "white collar" factories. They have reorganized their white collar factories, moving away from junctional organization toward proce...

This paper documents a hallmark feature of China’s state capitalism as the state controlling the economy in a vertical economic structure: State-owned enterprises (SOEs) monopolize key industries and markets in the upstream, whereas the downstream industries are largely open to private competition. We develop a general-equilibrium model to show that this unique vertical structure, when combined...
