Traders in the financial world are assessed by the amount of money they make and, increasingly, by the amount of money they make per unit of risk taken, a measure known as the Sharpe Ratio. Little is known about the average Sharpe Ratio among traders, but the Efficient Market Hypothesis suggests that traders, like asset managers, should not outperform the broad market. Here we report the findin...

Fourth party logistics (4PL) company plays the role of integrator, which provides both information technology and supply chain integration capabilities. It not only creates different values of each segment in the supply chain, but also elevates the effects in supply chain management for business. Therefore, how to select an appropriate fourth party logistics company is an important decision for...

—Many aspects of small-scale fisheries hinder our efforts to understand their dynamics, as required for sustainable management. For example, there is no widely accepted definition of small-scale fisheries or global data on number of small-scale fishers and their catches. One reason for this is that most research on small-scale fisheries is done at community level and tends to focus on immediate...

BACKGROUND For most patients with cancer pain, the World Health Organization's three-step analgesic ladder provides adequate management with oral or transdermal options. However, some cancer patients are not well palliated with these approaches. METHODS The author reviews interventional options that include nerve blocks, spinal administration of local anesthetics, opioids, alpha-2 agonists, s...

World Wide Web authors must cope in a hypermedia environment analogous to second-generation computing languages, building and managing most hypermedia links using simple anchors and single-step navigation. Following this analogy, sophisticated application environments on the World Wide Web will require thirdand fourthgeneration hypermedia features. Implementing thirdand fourth-generation hyperm...

Over a decade ago, Henry Jenkins [17] wrote “‘Complete freedom of movement’: Video Games as gendered play spaces” in which he argued that video games provide a contemporary alternative to the out of doors freedom of movement boys historically accessed. Video games operate like a ‘fourth space’ (a term coined by Van Vliet), a muchneeded alternative to the adult-supervised and structured spaces o...

Abstract There had been remarkable progress in developing third-generation electron storage rings as the main sources of very bright photon beams. Fourth-generation based on multi-bend achromat lattice concept may be able to surpass brightness and coherence that are attained using present rings. In this paper, we survey ongoing work around world develop concepts designs for fourth-generation

Wen LU, Shao-bo WANG, Rui WANG Institute of Meteorology & oceanography, PLA University of Science & Technology, Nanjing 211101, China Introduction: WindSat is the first spaceborne fully polarimetric microwave radiometer in the world. It can measure the third and fourth Stokes parameters of the target and provide a new way for sea ice remote sensing. By using WindSat data in 2004, we studied on ...
