In this short note, we demonstrate that the existence of one-way functions implies the existence of an ω(1)-round simultaneously resettable witness indistinguishable argument of knowledge.

A common task in research is to compare the averages of two or more populations (groups). We might want to compare the income level of two regions, the nitrogen content of three lakes, or the effectiveness of four drugs. The one-way analysis of variance compares the means of two or more groups to determine if at least one mean is different from the others. The F test is used to determine statis...

We introduce and motivate the concept of unclonable group identification, that provides maximal protection against sharing of identities while still protecting the anonymity of users. We prove that the notion can be realized from any one-way function and suggest a more efficient implementation based on specific assumptions.

As lawyers concerned with the regulation of economic activity, we applaud the recognition in Professor Charles Goodhart’s recent Chorley lecture that much of the ‘law and economics’ of the past quarter-century has involved ‘too much one-way traffic’. If law and economics has indeed largely, as Professor Goodhart suggests, consisted of a process of intellectual imperialism, specifically of the c...

The primary purpose of this study is to examine science student teachers' experience with educational technology, their intentions for their own use, their intentions for their students’ use, and their beliefs in the value of educational technology in science instruction. Four-hundred-forty-eight science student teachers of different disciplines and levels participated in the study. A questionn...

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...

Philosophers are very fond of making non-factualist claims—claims to the effect that there is no fact of the matter as to whether something is the case. But can these claims be coherently stated in the context of classical logic? Some care is needed here, we argue, otherwise one ends up denying a tautology or embracing a contradiction. In the end, we think there are only two strategies availabl...

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...

Understanding and evaluating the health e€ects of prolonged exposure to low radiation doses, as opposed to shorter exposure to higher doses, has still a long way to go. Answers to these questions cannot be provided by epidemiological studies alone, and so the input of radiobiologists to help focus the work of epidemiologists will become increasingly important in the future. This paper discusses...
