Food Stamp Program and Consumption Choices
We study the effect of the Food Stamp Program (FSP) on consumption patterns in families headed by low-educated single mothers in the U.S. using the Consumer Expenditure Surveys for 1994-2004. Our analysis suggests that the food stamp caseload does not have any statistically significant association with per capita expenditure on food in families headed by low-educated single mothers. We find that state and federal welfare reforms during the 1990s lowered the food stamp caseload by approximately 18 percent and the introduction of the Electronic Benefit Transfer cards and simplified reporting procedures for recertification of food stamps increased participation by about seven percent. However, we do not find any evidence that these policies had any effect on total food expenditure, nor do we find any consistent evidence that the policies affected expenditures on specific food items.

Microbial enrichment culture responsible for the complete oxidative biodegradation of 3‑Amino-1,2,4-triazol-5-one (ATO), the reduced daughter product of the insensitive munitions compound 3‑Nitro-1,2,4-triazol-5-one (NTO)
3-Nitro-1,2,4-triazol-5-one (NTO) is one of the main ingredients of many insensitive munitions, which are being used as replacements for conventional explosives. As its use becomes widespread, more research is needed to assess its environmental fate. Previous studies have shown that NTO is biologically reduced to 3-amino-1,2,4-triazol-5-one (ATO). However, the final degradation products of ATO are still unknown. We have studied the aerobic degradation of ATO by enrichment cultures derived from the soil. After multiple transfers, ATO degradation was monitored in closed bottles through measurements of inorganic carbon and nitrogen species. The results indicate that the members of the enrichment culture utilize ATO as the sole source of carbon and nitrogen. As ATO was mineralized to CO₂, N₂, and NH₄⁺, microbial growth was observed in the culture. Co-substrates addition did not increase the ATO degradation rate. Quantitative polymerase chain reaction analysis revealed that the organisms that enriched using ATO as carbon and nitrogen source were Terrimonas spp., Ramlibacter-related spp., Mesorhizobium spp., Hydrogenophaga spp., Ralstonia spp., Pseudomonas spp., Ectothiorhodospiraceae, and Sphingopyxis. This is the first study to report the complete mineralization of ATO by soil microorganisms, expanding our understanding of natural attenuation and bioremediation of the explosive NTO.Journal ArticleFinal article publishe
Approximate Personal Name-Matching Through Finite-State Graphs
This article shows how finite-state methods can be employed in a new and different task: the conflation of personal name variants in standard forms. In bibliographic databases and citation index systems, variant forms create problems of inaccuracy that affect information retrieval, the quality of information from databases, and the citation statistics used for the evaluation of scientists' work. A number of approximate string matching techniques have been developed to validate variant forms, based on similarity and equivalence relations. We classify the personal name variants as nonvalid and valid forms. In establishing an equivalence relation between valid variants and the standard form of its equivalence class, we defend the application of finite-state transducers. The process of variant identification requires the elaboration of: (a) binary matrices and (b) finite-state graphs. This procedure was tested on samples of author names from bibliographic records, selected from the Library and Information Science Abstracts (LISA) and Science Citation Index Expanded (SCI-E) databases. The evaluation involved calculating the measures of precision and recall, based on completeness and accuracy. The results demonstrate the usefulness of this approach, although it should be complemented with methods based on similarity relations for the recognition of spelling variants and misspellings

Lessons learned from professional development workshops on using GIS to teach geography and history in the K-12 classroom
A GIS oriented professional development activity engaged social studies teachers with the importance of maps and graphics in teaching geography and history. With an introduction to ArcGIS Online and National Geographic Map Maker, the activity provided teachers with the ability to make their own maps and identify GIS materials for their classrooms. Conducting the workshop reinforced our belief in the need for considerable hands-on activity with participants allowed to work at their own pace. Pre- and post-event surveys showed positive gains regarding the teachers’ likelihood to include GIS based maps and graphics in teaching. The activity provided teachers with enough knowledge of GIS that they were ready to use the technology immediately
Different Dialects - a World Conversation on Work Integrated learning
Lisa Ward (University of Huddersfield) and Ron Laird (University of Ulster) will provide conference with an insight to selected themes from recent Work Integrated Learning conferences and symposia. Their dialogue will enable delegates to hear of developments and practice from around the world of co-operative education. Their observations should enable all delegates to evaluate aspects of their own practice within a wider international context and lead to improvement
