Descriptions of new luperine genera and species from Mexico : with keys to related taxa (Coleoptera: Chrysomelidae: Galerucinae)

The section Scelidites ofthe subtribe Luperina is diagnosed and described. A key is provided to separate the genera within this section. Cyphotarsis Jacoby is reduced to a junior synonym of Metacoryna Jacoby. Microscelida, new genus, is erected to include Agelastica viridis Jacoby, Luperus subcostatus Jacoby, Luperus subglabratus Jacoby, Scelidopsis violacea Jacoby, and seven newly described species. A key and diagnoses are provided to enable recognition of each species within this new genus. Scelidacne, new genus, is erected to include a single newly described species

The Rational Hybrid Monte Carlo Algorithm

The past few years have seen considerable progress in algorithmic development for the generation of gauge fields including the effects of dynamical fermions. The Rational Hybrid Monte Carlo (RHMC) algorithm, where Hybrid Monte Carlo is performed using a rational approximation in place the usual inverse quark matrix kernel is one of these developments. This algorithm has been found to be extremely beneficial in many areas of lattice QCD (chiral fermions, finite temperature, Wilson fermions etc.). We review the algorithm and some of these benefits, and we compare against other recent algorithm developements. We conclude with an update of the Berlin wall plot comparing costs of all popular fermion formulations.Comment: 15 pages. Proceedings from Lattice 200

The Western North American Genus Androlyperus Crotch, 1873 (Coleoptera: Chrysomelidae: Galerucinae)

The five previously known species of Androlyperus are redescribed and diagnosed. Androlyperus nataliae n. sp. is described from the Baja California Peninsula, Mexico. A taxonomic key is provided to facilitate species identification

A broad character education approach for addressing America’s cheating culture

Cheating is highly prevalent in American high school students and across the globe. Although numerous approaches are in place to combat this issue, most character education approaches have focused primarily on fostering moral integrity (a strength of moral character). Here, we argue that a broad character education approach to addressing cheating culture—one drawing on moral, civic, performance, and intellectual character strengths – may provide new ways to address this epidemic. We begin by outlining current scholarship and approaches to addressing cheating. We then note that many of these interventions aim to foster academic integrity through a moral lens and posit that a broad character education approach that draws on all four areas of character (not moral character alone) may provide additional avenues for promoting student integrity and dissuading academic dishonesty. We discuss the potential benefits of building specific strengths within each character domain in relation to integrity, and offer suggestions for further research. Finally, we conclude with a discussion of how educators might leverage each of these character areas and the interplay between them to foster academic integrit

A geomorphological overview of glacial landforms on the Icelandic continental shelf

The availability of a bathymetric database that covers about 80% of the Icelandic shelf has made it possible to produce a geomorphological map of the glacial landforms. The digital elevation model of the bathymetry was analyzed as a series of shaded relief images. Trough edges, bulging trough mouths, moraines, eskers, melt water channels, streamlined bedrock and streamlined drift, mostly hitherto unmapped, distributed all around the island have been identified. Moraines are found on the shelf, within troughs and inside fjords. Streamlined landforms are always confined to the bottom of troughs. Troughs appear to have been cut by ice streams draining an ice sheet that likely covered the entire shelf. At the shelf break, most troughs terminate with contours that bulge in a convex-outwards fashion. This suggests that an ice stream eroded, transported and finally deposited large amounts of sediment at the trough mouth. Overall, the glacial morphology of the shelf highlights a radial pattern that indicates a main ice divide near the centre of Iceland

Five years of social security reforms in the UK

The current Labour Government was elected in 1997 with few specific social security proposals. This paper argues that after five years, consistent trends in social security policy have emerged: there is a willingness to increase benefits; a “work-first” focus; increasing centrality for benefits that relate to ‘need’, which has involved expanded means-testing; a downgrading of contributory benefits; and, a desire to reduce poverty by redistributing to particular demographic groups. Many of these characteristics of Labour policy, such as the size of caseloads or aggregate expenditure, are yet to show up in various aggregate data, and we argue that this is probably due to various counter-balancing socio-economic changes since 1997. Looking forward, we discuss what the introduction of new forms of means-test might achieve. We also suggest that it might be considered odd that Labour has left Housing Benefit and Council Tax Benefit unreformed, especially since a good chance to reform them without significant cost or low-income losers, has been missed

Credit where it's due? An assessment of the new tax credits

In 2003: the government will introduce new tax credits to provide financial support for children and low-paid workers: the integrated child credit and the employment tax credit. The reform to support for children aims to unify existing payments in a way that provides a guaranteed stream of income for those with children, whether they are working or not. The credit for people in work will provide an income top-up for low earners - something that those without children have not benefited from before. The government has not announced the impact of the reforms on the public finances, but both will cost the exchequer money, so this Commentary considers the likely sums involved. We also examine whether the reforms look like fulfilling their stated aims: making work pay, relieving poverty and creating a new type of state support that is simpler and less intrusive for claimants
