Motivated by the extremely low level of CBOE VIX accompanied high U.S. economic policy uncertainty in period late 2016 to end 2017, we examine factors affecting relationship between market volatility and United States Kingdom. Our analysis shows that low-quality political signals, higher opinion divergence among investors, exceptional equity performance consistently weaken positive implied unce...

geographical concept of “haft karšvar” could be traced back to the proto-indo-iranian period. after the separation of indians and iranians, due to geographical circumstances and religio-political changes, original indo-iranian narrative of seven part of the earth, turned into its current versions. a comparison of old iranian and indian texts, specially avesta and vīspā̊ŋhō  purāṇa, shows that in...

Variable selection via penalized estimation is appealing for dimension reduction. For penalized linear regression, Efron, et al. (2004) introduced the LARS algorithm. Recently, the coordinate descent (CD) algorithm was developed by Friedman, et al. (2007) for penalized linear regression and penalized logistic regression and was shown to gain computational superiority. This paper explores...

What effect does political instability in the form of a potential secession from union have on business formation? Using newly collected data creation, we show that entrepreneurial activity Ireland late nineteenth century was much lower than Scotland, and this divergence fluctuated over time. Several factors may contributed to this, but argue uncertainty about prospect devolved government playe...

While various forms of corruption are common in many health systems around the world, defining wrongdoing in terms of legality and the use of public office for private gain obstructs our understanding of its nature and intractability. To address this, I suggest, we must not only break the silence about the extent of wrongdoing in the health sector, but also talk differe...

TECHNOLOGY—the societal process for the pro duction and operation of artifacts, both tangible and intangible—impacts virtually every other so­ cietal structure and process and is, in turn, influenced by them. From its inception at the early emergence of humans as a distinct species, technology was the in­ strument that extended our biological capabilities, eventually making possible increasingl...

the alluvial fan of shahdaad in derakhtangaan river is one of the biggest alluvial fans in a dry area in northeastern kerman. this alluvial fan has been formed due to different material erosions in the drainage basin of derakhtangaan river and lying of these materials in the extreme part of this basin called dasht-e-lut (the plain of lut). the region which has been studied in this research is o...

Compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (NPR) have been numerically studied with severalturbulence models. The numerical results reveal that, the SST k–ω model give the bestresults compared with other models in time and accuracy. The effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...
