Self-regulatory failure and intimate partner violence perpetration.

Abstract: Five studies tested the hypothesis that self-regulatory failure is an important predictor of intimate partner violence (IPV) perpetration. Study 1 participants were far more likely to experience a violent impulse during conflictual interaction with their romantic partner than they were to enact a violent behavior, suggesting that self-regulatory processes help individuals refrain from perpetrating IPV when they experience a violent impulse. Study 2 participants high in dispositional self-control were less likely to perpetrate IPV, in both cross-sectional and residualized-lagged analyses, than were participants low in dispositional self-control. Study 3 participants verbalized more IPV-related cognitions if they responded immediately to partner provocations than if they responded after a 10-s delay. Study 4 participants whose self-regulatory resources were experimentally depleted were more violent in response to partner provocation (but not when unprovoked) than were nondepleted participants. Finally, Study 5 participants whose self-regulatory resources were experimentally bolstered via a 2-week training regimen exhibited less violent inclinations than did participants whose self-regulatory resources had not been bolstered. These findings hint at the power of incorporating self-regulation dynamics into predictive models of IPV perpetration.

A room temperature single photon source in silicon carbide

Abstract: We report the first observation of stable single photon sources in an electronic and photonic device-friendly material, silicon carbide (SiC). SiC is a viable material for implementing quantum communication, computation and photonic technologies.

Public Sector to Public Services: 20 Years of 'Contextual' Accounting Research

Abstract: Purpose - The purpose of this paper is to review and critique the field of public sector accounting research. Many nation states deliver essential public services. In recent times, many of these nations have been involved in programmes of "modernisation", which, in part, means that these public services now are significantly managed, delivered and governed by private and third sector organisations. Design/methodology/approach - The paper employs a literature-based analysis and critique of public sector accounting articles published in the selected journals from 1992 to 2006. From this, a descriptive meta-analysis of the characteristics of the research will be discussed. Finally, a conceptual analysis of the selected literature will be used to evaluate the field and address a possible future research agenda. Findings - The descriptive analysis highlights that among the research papers reviewed several interesting patterns emerged concerning public service research. Also, the dominance of Australasia and UK research was noted. The extent of research in different levels of government/jurisdiction indicated that the majority of research was organisationally based. Finally, when the various functional types of accounting are considered, management accounting remained the most researched area of interest. Research limitations/implications - The paper only considered research within eight selected journals and over the period 1992 to 2006. Therefore, for instance, US mainstream public sector accounting research has not been reviewed. Originality/value - The main implications of the paper are that "contextual" public service accounting research has a strong tradition and, through the process of reflection and critique of the body of work, several important insights are provided in order to highlight areas for further research and policy development.

Making NTRU as secure as worst-case problems over ideal lattices

Abstract: NTRUEncrypt, proposed in 1996 by Hoffstein, Pipher and Silverman, is the fastest known lattice-based encryption scheme. Its moderate key-sizes, excellent asymptotic performance and conjectured resistance to quantum computers could make it a desirable alternative to factorisation and discrete-log based encryption schemes. However, since its introduction, doubts have regularly arisen on its security. In the present work, we show how to modify NTRUEncrypt to make it provably secure in the standard model, under the assumed quantum hardness of standard worst-case lattice problems, restricted to a family of lattices related to some cyclotomic fields. Our main contribution is to show that if the secret key polynomials are selected by rejection from discrete Gaussians, then the public key, which is their ratio, is statistically indistinguishable from uniform over its domain. The security then follows from the already proven hardness of the R-LWE problem.
