A general parameter process defined by a continuum of random variables is not jointly measurable with respect to the usual product σ-algebra. For the case of independent random variables, a one-way Fubini extension of the product space was constructed in [11] to satisfy a limited form of joint measurability. For the general case we show that this extension exists if and only if there is a count...

In any distance-education situation students and tutors are at a distance from each other at least in the sense that they are not in the same room while learning and teaching. This means that distance education relies on media. It has two constituent elements, on the one hand the presentation of learning matter, which can be described as one-way traffic, on the other hand interaction between st...

Last week we learned about one-way designs. They examine several levels of a single factor. For instance, we might examine the effect of StudyType (independent variable) on LanguagePerformance (dependent variable). Classroom study Self-study Control Perhaps we think that the StudyType manipulation might only affect one gender or the other. We could do a two-way design whether a second factor, G...

easyJet, one of Europe’s most successful low-cost short-haul airlines, has a simple pricing structure. For a given flight, all prices are quoted one-way, a single price prevails at any point, and, in general, prices are low early on and increase as the departure date approaches. We observe from these policies and from the empirical section of this paper that easyJet employs three distinct strat...

This paper derives tests for skewness and kurtosis for the one-way error components model. The test statistics are based on the between and within transformations of pooled OLS residuals, and are derived in a conditional moments framework. We derive the limiting distribution of the test statistics for panels with large cross-sectional and fixed time-series dimensions. The tests are implemented ...

We show that a variant of the one-way model where one only allows X and Y one qubit measurements is approximately universal.

We demonstrate how to make voting protocols resistant against manipulation by computationally bounded malicious voters, by extending the previous results of Conitzer and Sandholm in several important directions: we use one-way functions to close a security loophole that allowed voting officials to exert disproportionate influence on the outcome and show that our hardness results hold against a ...
