Uniform Approximation of Abhyankar Valuation Ideals in Smooth Function Fields

In this paper we use the theory of multiplier ideals to show that the valuation ideals of a rank one Abhyankar valuation centered at a smooth point of a complex algebraic variety are approximated, in a quite strong sense, by sequences of powers of fixed ideals. Fix a rank one valuation v centered at a smooth point x on an algebraic variety over a field of characteristic zero. Assume that v is Abhyankar, that is, that its rational rank plus its transcendence degree equal the dimension of the variety. Let a_m denote the ideal of elements in the local ring of x whose valuations are at least m. Our main theorem is that there exists e>0 such that a_{mn} is contained in (a_{m-e})^n for all m and n. This can be viewed as a greatly strengthened form of Izumi's Theorem for Abhyankar valuations centered on smooth complex varieties.Comment: 27 pages, late

Cocaine's appetite for fat and the consequences on body weight.

For many individuals in treatment for cocaine dependence, weight gain is a substantial problem during recovery. This weight gain causes significant distress and seems to increase the risk of relapse. The mechanisms underlying cocaine's effects on weight remain elusive. It is widely assumed that this weight gain reflects a metabolic or behavioural compensatory response to the cessation of cocaine use. Here we challenge this assumption and outline potential mechanisms by which chronic cocaine use produces disturbances in the regulation of fat intake and storage, through its effects on the central and peripheral nervous systems, specifically the sympathetic nervous system. We hypothesize that the cocaine-induced alteration in fat regulation results in cocaine users developing a pronounced appetite for fatty food but keeps their fat mass low. This altered fat appetite subsequently leads to excessive weight gain when individuals enter treatment and stop using cocaine. Our aim is to shed light on the neurobiological mechanisms that may underlie the alterations in eating and fat regulation in cocaine-dependent individuals, to open up potential new avenues to support these individuals in recovery.LB is the recipient of a Wellcome Trust Vacation Scholarship and KDE is supported by the Medical Research Council (G1000018).

Social Work and Social Services in Europe - a changing landscape

Este artículo analiza algunas de las diferencias y similitudes, así como las posibles áreas de convergencia, en las políticas de bienestar social, la organización de los Servicios Sociales, las preocupaciones, y la educación y formación de los profesionales sociales en Europa. Se centra especialmente en la Unión Europea como un bloque político dentro de una Europa más amplia, e identifica algunos aspectos de su función en la elaboración de las políticas y prácticas nacionales, incluyendo los ámbitos de la migración y la educación superior. Plantea que las influencias de las tendencias mundiales y regionales de una gran movilidad internacional de la población, conlleva que las profesiones sociales puedan verse cada vez más inmersas en intervenciones «transnacionales» y que, por lo tanto, hayan de ser conscientes de que los sistemas de bienestar y las actuaciones y prácticas profesionales van más allá de las fronteras nacionales. El respeto por la diversidad cultural y el compromiso con la promoción de los derechos humanos y la justicia social, nacional e internacional, se consideran valores esenciales que deben ser compartidos por las profesiones sociales en Europa, y adoptados por los organismos regionales de representación profesional y educativa.This article considers some of the variations and similarities, as well as possible areas of convergence, in social welfare policies; the organisation of social services; the concerns; and the education and training of social professionals across Europe. It focuses particularly on the European Union as a political bloc within a wider Europe, and identifies some aspects of its role in shaping national policies and practices, including in the fields of migration and higher education. It presumes that global and regional trends and influences, together with international population mobility, indicate that social professionals may find themselves increasingly drawn into «trans-national» interventions and that they therefore need to be aware of welfare systems and professional policies and practices beyond national borders. Respect for cultural diversity and commitment to the promotion of human rights and social justice, nationally and internationally, are regarded as essential values to be shared by social professionals across Europe, as espoused by regional bodies representing social professionals and educators

Saybrook Manufacturing: Is Cross-Collateralization Moot?

This article examines the Saybrook decision in the context of prior case law and the general principles underlying the Code. The first section lays the foundation for an analysis of Saybrook by identifying the fundamental tenets of the Code and outlining the protections available under the Code to preserve secured creditors\u27 property interests in their collateral and to induce lenders to provide DIPs with new credit. The next section defines cross-collateralization, analyzes the Saybrook decision in the context of prior case law, and considers whether cross-collateralization is permissible under the Code\u27s express provisions and general policies. The authors conclude that the Code\u27s language, history, and policies should be construed to prohibit cross-collateralization liens because such liens violate the Code\u27s policy of equitable distribution among similarly situated creditors and are inconsistent with the provisions of the Code governing the protection of pre-petition secured creditors and the inducement of new financing. The article next considers whether and to what extent financing orders are protected from modification or reversal on appeal or in collateral proceedings, and concludes that (1) the Code\u27s statutory mootness doctrine applicable to financing orders should be construed to protect against reversal or modification on appeal all terms of a financing order that relate directly to the new post-petition financing, unless the effect of the order has been stayed pending the appeal, but not to protect any terms that relate directly to the lender\u27s prepetition claims, even in the absence of a stay pending appeal and (2) principles of finality, res judicata and collateral estoppel should insulate all terms of a financing order from direct or collateral attack by any party who failed to preserve its challenge by filing a timely notice of appeal. This is followed by an attempt to project Saybrook\u27s potential precedental effects and impact on DIP financing. Finally, the authors offer a summary of their conclusions and make certain recommendations designed to guide practitioners and courts in drafting and analyzing financing orders

Cis-regulatory basis of sister cell type divergence in the vertebrate retina

Multicellular organisms evolved via repeated functional divergence of transcriptionally related sister cell types, but the mechanisms underlying sister cell type divergence are not well understood. Here, we study a canonical pair of sister cell types, retinal photoreceptors and bipolar cells, to identify the ke

Extension Master Gardener Social Media Needs: A National Study

An online survey was conducted to assess the feasibility of providing training on the use of social media for the Extension Master Gardener (EMG) program. Volunteers (n = 1,275) and coordinators (n = 111) responded. Findings indicate the existence of sufficient interest in a nationally coordinated social media training. Inclusion of social media as a qualifying activity in EMG programs should be explored. Findings support inclusion of volunteers in future surveys and the possible need for increased involvement of volunteers in setting program direction. Training is being developed on the basis of the data. Future surveying of the EMG population by using random sampling to more accurately define the audience is strongly encouraged
