Evaluation of Learner Support Funds: final report 2003

"This report is the culmination of a two year evaluation of the Learner Support Funds for the Department for Education and Skills (DfES). These funds are available to students across the FE sector and are designed to support disadvantaged individuals with the additional costs of studying (eg books, equipment, transport, childcare and the costs of residential study) in order to encourage participation, retention, achievement and progression." - Page 8

Quaking Aspen Ecology on Forest Service Lands North of Yellowstone National Park

Quaking aspen (Populus tremuloides) occupy a small area in the northern Rocky Mountains, but are highly valued as wildlife habitat. Aspen stands in and around Yellowstone National Park commonly consist of few, large, mature overstory stems and numerous root suckers that do not grow above the browsing reach (≈ 2 m) of most wild ungulates. Our primary objective was to determine if the recruitment or density of aspen stems \u3e 2 m tall had changed from 1991 to 2006 on a portion of the Gallatin National Forest. The same aspen stands were surveyed in 1991 and 2006 in the 560 km² study area (n = 316). Secondary objectives were to determine if aspen density was influenced by elk (Cervus elaphus) browsing, conifer establishment, and cattle (Bos spp.) grazing. Mean recruitment stem density did not change from 1991 to 2006 (P = 0.95). Density of stems \u3e 2 m declined 12 percent from 1991 to 2006 (P = 0.04), which indicates that recruitment stems are not being produced at a sufficient rate to replace aging overstories. Areas with the greatest elk densities had the lowest recruitment stem densities and contributed the most to the decline. Although elk browsing seemed to play the largest role, conifer establishment and cattle grazing have also negatively impacted overstory recruitment in aspen stands. Even though elk numbers on the Northern Yellowstone Winter Range have declined since wolf reintroduction, aspen recruitment has not increased at the landscape level on the Gallatin National Forest

Oligopolistic manufacturing and economic reform in four archetype western pacific economies: model construction and analysis

To examine the effects of policy intervention in the presence of imperfect competition in manufacturing, general equilibrium models are constructed of four Western Pacific economies, chosen according to their level of development and the comparative sizes of their manufacturing sectors. The countries chosen are Australia, an industrialised importer of manufactures, Japan, an industrialised exporter, the Philippines, a developing importer, and the Republic of Korea, a developing exporter. In each case the manufacturing sector is characterised as comprising nine separate industries, each with identical oligopolistic firms producing homogeneous goods which are differentiated from competing imports. The economies are subjected to exogenous shocks, which include trade reforms, increased surveillance of pricing behaviour, technological change and shifts in the terms of trade. Differences in the simulated economic responses in each case are examined and discussed. This paper also offers a complete specification of the model used and a detailed description of the construction of databases for the four countries

Rule-Based Machine Translation From Kazakh To Turkish

This paper presents a shallow-transfer machine translation (MT) system for translating from Kazakh to Turkish. Background on the differences between the languages is presented, followed by how the system was designed to handle some of these differences. The system is based on the Apertium free/open-source machine translation platform. The structure of the system and how it works is described, along with an evaluation against two competing systems. Linguistic components were developed, including a Kazakh-Turkish bilingual dictionary, Constraint Grammar disambiguation rules, lexical selection rules, and structural transfer rules. With many known issues yet to be addressed, our RBMT system has reached performance comparable to publicly-available corpus-based MT systems between the languages

Grizzly Bear Scavenging of Carrion on the Northern Yellowstone Winter Range (1997-2012)

The Northern Yellowstone Winter Range (NYWR) in northwestern Wyoming and southwestern Montana is an important winter migratory destination for ungulates.  The NYWR is within the Greater Yellowstone Ecosystem (GYE), a landscape characterized by a complex ecological system of predators, scavengers, and ungulates.  Grizzly bears (Ursus arctos) are dominant members of the scavenging community throughout the spring.  However, little is known about factors associated with grizzly bear use of carcasses.  Of particular interest to managers is how habitat and anthropogenic factors are associated with carcass use.  Such information, for example, may be useful to manage spring recreation in important bear foraging areas to reduce conflict and support conservation efforts.  We used logistic regression to analyze spring survey data from 23 transects located in Yellowstone National Park and the Gallatin National Forest during 1997–2012, to identify factors associated with grizzly bear scavenging of winter- or predator-killed ungulates.  Multi-model inference was used to evaluate relative support for a set of a priori candidate models containing environmental and temporal correlates. Our preliminary findings showed support for models with distance to forest edge, road density, and elevation. Results indicated negative relationships between these factors and probability of carcass use.  Our results suggest that spatial heterogeneity in landscape-level habitat characteristics and human activity affect grizzly bear use of a valuable spring food source

The BioGRID Interaction Database: 2011 update

The Biological General Repository for Interaction Datasets (BioGRID) is a public database that archives and disseminates genetic and protein interaction data from model organisms and humans (http://www.thebiogrid.org). BioGRID currently holds 347 966 interactions (170 162 genetic, 177 804 protein) curated from both high-throughput data sets and individual focused studies, as derived from over 23 000 publications in the primary literature. Complete coverage of the entire literature is maintained for budding yeast (Saccharomyces cerevisiae), fission yeast (Schizosaccharomyces pombe) and thale cress (Arabidopsis thaliana), and efforts to expand curation across multiple metazoan species are underway. The BioGRID houses 48 831 human protein interactions that have been curated from 10 247 publications. Current curation drives are focused on particular areas of biology to enable insights into conserved networks and pathways that are relevant to human health. The BioGRID 3.0 web interface contains new search and display features that enable rapid queries across multiple data types and sources. An automated Interaction Management System (IMS) is used to prioritize, coordinate and track curation across international sites and projects. BioGRID provides interaction data to several model organism databases, resources such as Entrez-Gene and other interaction meta-databases. The entire BioGRID 3.0 data collection may be downloaded in multiple file formats, including PSI MI XML. Source code for BioGRID 3.0 is freely available without any restrictions
