Abstract Amongst young people in Freetown, ‘Temple Run’, a mobile phone game that requires the player to run for their life across treacherous obstacles, is used as code perilous journey an increasing number of Sierra Leoneans made Europe via Libya. Through ethnographic accounts, article discusses role dreams migration Freetown youths’ articulations distinctive political imagination through whi...

Distribution-free (nonparametric) control charts can be useful to the quality practitioner when the underlying distribution is not known. A Phase II nonparametric CUSUM chart based on the exceedance statistics, called the exceedance CUSUM chart, is proposed here for detecting a shift in the unknown location parameter of a continuous distribution. The exceedance statistics can be more efficient ...

We discuss the tension between some of the recent evidence of path dependence in urban location with recent efforts to analyze calibrated models of city sizes. One strand of recent work, including some of our own, finds evidence of persistent city sizes following the obsolescence of historical advantages. This literature argues that such persistence cannot be understood as the medium-run effect...

In this paper, we investigate the long run dynamics of the intraday range of the GBP/USD, JPY/USD and CHF/USD exchange rates. We use a non-parametric filter to extract the low frequency component of the intraday range, and model the cyclical deviation of the range from the long run trend as a stationary autoregressive process. We find that the long run trend is time-varying but highly persisten...

OBJECTIVE To define the performance characteristics of the LOCI® method for cardiac troponin I on the Dimension EXL system. DESIGNS AND METHODS Three different levels of commercial control (mean concentrations 0.426, 1.42, and 18.64 µg/L) were used for the imprecision study, quantifying separately within-run and between-run over 20 days. The limit of blank (LoB) and limit of detection (LoD) w...

Abstract The goal of this study is to assess the strength and mode price dependence by time scale, among extra virgin olive oil markets Italy, Spain, Greece. These three Mediterranean countries are responsible for 95% production within European Union they account more than 50% exports worldwide. For empirical analysis, monthly prices from aforementioned utilized along with tools discrete wavele...

the main objective of this study was to evaluate the response of consumers to changes in income and prices of chicken meat in the short run and long run. in order to achieve this goal, vector auto regression (var) and vector error correction model (vecm) have been applied to data since 1974 to 2007. impulse response function (irf) calculation indicated that past and present consumption of chick...

We present a new method to retrieve molecular abundances and temperature profiles from exoplanet atmosphere photometry and spectroscopy. We run millions of one-dimensional (1D) atmosphere models in order to cover the large range of allowed parameter space. In order to run such a large number of models, we have developed a parametric pressure–temperature (P–T) profile coupled with line-by-line r...
