This chapter discusses the difficult problem of evaluating deployed security-focused decision support systems. In a security setting, one can never expect the adversary to cooperate in evaluation, which disallows many kinds of controlled studies. Furthermore, data is typically sparse — there are thankfully relatively few terrorist attacks on major infrastructure in the U.S. Still, evaluating se...

Sedentary behaviour is an emerging risk factor for poor health. This study aimed to identify ecological determinants of sedentary behaviour, for which evidence is currently scarce. The study participants were community dwelling adults from, respectively, the Lothian Birth Cohort 1936 (n = 271, mean age 79) and the 1930s (n = 119, mean age 83) and 1950s (n = 310, mean age 64) cohorts of the West...

abstract main objective of this paper is to investigate the impact of exchange rate misalignment on wheat’s producer estimates (pse), using the 1989-2007 period’s data. for this purpose, vector error correction model (vecm) along with the use of real exchange rate based on purchasing power party (ppp) was applied to estimate nominal equilibrium exchange rates. then, by using market price suppor...

in this work are studied the jacobians of certain singular transformations and the corresponding measures which support the jacobian computations.
