Geology Programs and Disciplinary Accreditation

This report raises the question of whether accreditation may be coming to the geology discipline, and attempts to quantify the positions on accreditation of academic department heads/chairs. The study makes a distinction between institutional and specialized (or disciplinary) accreditation and explores attitudes toward both types. Results of the analysis are presented with a discussion of two methods of data interpretation, a multivariate analysis technique and the Chi square test for heterogeneity or independence. The report concludes that there is currently insufficient support for establishing disciplinary accreditation in geology. Educational levels: Graduate or professional

Trivializations of differential cocycles

Associated to a differential character is an integral cohomology class, referred to as the characteristic class, and a closed differential form, referred to as the curvature. The characteristic class and curvature are equal in de Rham cohomology, and this is encoded in a commutative square. In the Hopkins--Singer model, where differential characters are equivalence classes of differential cocycles, there is a natural notion of trivializing a differential cocycle. In this paper, we extend the notion of characteristic class, curvature, and de Rham class to trivializations of differential cocycles. These structures fit into a commutative square, and this square is a torsor for the commutative square associated to characters with degree one less. Under the correspondence between degree 2 differential cocycles and principal circle bundles with connection, we recover familiar structures associated to global sections.Comment: 20 pages; several minor corrections/revisions in v

Techno-surveillance of the roads: High impact and low interest

Copyright © 2010 Palgrave Macmillan. This is a post-peer-review, pre-copyedit version of an article published in Crime Prevention and Community Safety. The definitive publisher-authenticated version Crime Prevention and Community Safety 10(1): 1-18 is available online at the link below.Road crashes and road crime are huge international problems produced by global society’s increasing dependence on motorised transport. To help reduce these crash and crime statistics, roads technology is rapidly developing to prevent the former and deter the latter. This technology largely works by vehicle surveillance, and as with surveillance technology used in other arenas of crime prevention, drawbacks and dangers go along with the safety and security enhancing aspects. This paper reviews some key emerging roads technologies, the theoretical concerns raised by them and how, through various theoretical frameworks, they could be explored by the discipline of criminology. It urges that the surveillance aspects of road crime prevention and the study of vehicle-related crime more generally would benefit from criminological consideration and be theoretically rewarding. Moreover, in view of the centrality of the roads in contemporary life and the extent of global harm caused there, it contends that criminology should engage with this terrain

Chartering Turnaround: Leveraging Public Charter School Autonomy to Address Failure

Persistently low-achieving public schools around the country have received $5.8 billion from the federal School Improvement Grant (SIG) program, in addition to district and state funds, and other supplementary federal funds. Despite all of these sources of funding, most of the schools receiving them have failed to make a dramatic difference in improving student achievement. However, according to a new report jointly released by the National Alliance for Public Charter Schools and the Center on School Turnaround, autonomy provided by state charter laws can be better leveraged to improve school turnaround efforts.The report, Chartering Turnaround: Leveraging Public Charter School Autonomy to Address Failure, provides case studies of three charter management organizations (CMOs) that have successfully restarted low-achieving public schools, adding a valuable component to the limited body of research that exists about turnaround models. The report highlights the freedoms that benefit poor-performing schools most significantly, including: the autonomy to hire, retain and reward staff; the ability to adjust the length of school year, academic program and curriculum; and, the option to develop tailored approaches for finances and facilities

Driving offences

Copyright @ 2010, Taylor & Francis Group. This material is posted on this site with the permission of the publishers.This chapter on driving offences will largely follow the template of earlier chapters except that owing to their vast number, a limited selection only will be examined based on their high volume, seriousness and public concern. The first section will define what driving offences are, how they developed alongside the emerging car culture, and it will consider the contemporary landscape. The second section will give a general overview of patterns and trends, those most likely to engage in road traffic offending, and kinds of explanations voiced by drivers and theoretical approaches used. The next three sections will follow a similar pattern and focus on speeding, bad driving – mostly dangerous and careless offences, and impaired driving – mostly drink-driving but mentioning drug-driving and fatigued driving. In addition, contemporary debates and key issues concerning each will be considered, along with official responses to each offence category comprising court-based penalties and other measures. The final section will draw the key threads and themes together, noting the danger of work-related driving. Given that up to a third of all road traffic collisions involve somebody at work at the time accounting for up to 20 fatalities and 250 serious injuries every week (DfT and HSE, 2003), the importance of reducing traffic offending is clear

An explicit conductor formula for GLn×GL1{\rm GL}_n \times {\rm GL}_1

We prove an explicit formula for the conductor of an irreducible, admissible representation of ${\rm GL}_n(F)$ twisted by a character of $F^{\times}$ where the field $F$ is local and non-archimedean. As a consequence, we quantify the number of character twists of such a representation of fixed conductor

Vehicle-related crime and the gender gap

Although vehicle-related offending and traffic offenders are of interest to some behavioural psychologists, criminologists have been less enthused and their concern has been largely restricted to crime to vehicles rather than crime by drivers or wider society. Both disciplines have, however, largely ignored the contribution of women to vehicle-related offending statistics, mirroring the pattern seen in regard to mainstream offending. This paper attempts to plug the gap by considering the relative contributions of men and women to motoring conviction data and self-report offending studies. To some extent it also does this by age, where evidence for a ‘ladette’ style of driving among young women is examined from the conviction data. In general, a gender gap similar to that in mainstream crime is noted, and key theoretical explanations that could account for this are assembled. Implications for improving road safety and research are then considered given this gap and emerging support for the non-homogeneity of female driving styles

A proof of the refined Gan--Gross--Prasad conjecture for non-endoscopic Yoshida lifts

We prove a precise formula relating the Bessel period of certain automorphic forms on ${\rm GSp}_{4}(\mathbb{A}_{F})$ to a central $L$-value. This is a special case of the refined Gan--Gross--Prasad conjecture for the groups $({\rm SO}_{5},{\rm SO}_{2})$ as set out by Ichino--Ikeda and Liu. This conjecture is deep and hard to prove in full generality; in this paper we succeed in proving the conjecture for forms lifted, via automorphic induction, from ${\rm GL}_{2}(\mathbb{A}_{E})$ where $E$ is a quadratic extension of $F$. The case where $E=F\times F$ has been previously dealt with by Liu.Comment: 38 pages in Forum Mathematicum (2016
