Undocumented: The Stress of Status

From 2010 to 2012 researchers from Fairfield University, Loyola University Chicago, and Santa Clara University talked to students who were undocumented and attending Jesuit colleges. The project culminated in a book, Undocumented and in College: Students and Institutions in a Climate of National Hostility (Fordham University Press, 2017)

Role of iron in the accumulation of glomalin, an arbuscular mycorrhizal fungal glycoprotein

Effects of iron on production of glomalin, an arbuscular mycorrhizal fungal glycoprotein, were examined. In a preliminary experiment comparing available (FeEDDHA) and unavailable iron (hematite), low amounts of glomalin were produced with the former while the latter total inhibited the symbiosis. Part of the effect of hematite was reduced spore germination. A glycoprotein cross-reacting with a monoclonal antibody against glomalin was produced in nonmycorrhizal pots. This molecule is similar to glomalin, but has some unique characteristics. Concentration increases when C3 and C4 grasses are stressed from low nutrients and/or light but levels are at least 10-fold less than glomalin. Two chelated iron sources, FeEDDHA and FeEDTA, at three concentrations resulted in glomalin accumulation at least 75% lower than normal resulting from environmental limitations. Glomalin concentration was independent of fungal biomass and iron source. To better test this interaction in the future, more optimum environmental conditions for plant growth are needed

Social work research development in the United States

This article summarizes and analyzes the outcomes of the recommendations extracted from the Plan for Research Development, produced in 1991 by a Task Force on Social Work Research created by the National Institute of Mental Health. The Plan responded to the claim of the profession identifying a crisis in social work research, due to the fact that very little time was spent on research to improve social work services and that less than ½ of 1% of members of the National Association of Social Workers – the largest professional social work organization - identified themselves as researchers. Almost 20 years later, it is today considered that the crisis has abated, but has not been eliminated. There is a continuing need for capacity building as well as dissemination research activities.Este artigo sumariza e analisa os resultados das recomendações emanadas pelo Plan for Research Development, realizado em 1991 por uma Task Force para a Investigação em Serviço Social criada pelo Instituto Nacional de Saúde Mental. O Plano veio responder à reivindicação do corpo profissional de que existia uma crise na investigação em Serviço Social, consubstanciada na constatação de que muito pouco tempo dos profissionais era utilizado na realização de pesquisa para melhorar os serviços e de que menos de metade de 1% dos membros da Associação Nacional de Assistentes Sociais – a maior organização profissional do Serviço Social – se via como investigador. Quase 20 anos depois, considera-se hoje que a crise cedeu, mas que não foi eliminada. Continua a existir uma necessidade de actividades de investigação ligadas ao reforço de capacidades e à disseminação de resultados

Child Support Enforcement Reform: Can It Reduce the Welfare Dependency of Families of Never-Married Mothers?

Among all groups of single-parent families, those created by a birth to an unmarried woman have the least likelihood of receiving child support and the greatest risk of becoming dependent on welfare. Wisconsin data indicate that child support reform-specifically the immediate income assignment-is improving child support payment performance. But the modest increases in payments to nonmarital children will have little effect on their welfare recipiency. The fathers of these children lack the economic resources to aid their families much in the short term. However, cost effectiveness should not be the only criterion used in enforcing child support. It is important to send the message to all parent that they are expected to assume responsibility for the children they bear

Collegiate Connection: A Program to Encourage the Success of Student Participation in High School/University Dual Enrollment

This project is a comparative exploration of academic success rates for high school students enrolled in a high school/university dual enrollment program. Four-hundred-eighty-four high school student grades in university courses were compared to grades of the general university population and university freshmen (n = 4,552) in specific courses. In several specific courses, the earned grades of high school students participating in the program were found to be significantly greater than the grades of university freshmen in matching courses. The Collegiate Connection dual enrollment program is explained in detail and suggestions for additional future research are also included

Experiences in deploying metadata analysis tools for institutional repositories

Current institutional repository software provides few tools to help metadata librarians understand and analyze their collections. In this article, we compare and contrast metadata analysis tools that were developed simultaneously, but independently, at two New Zealand institutions during a period of national investment in research repositories: the Metadata Analysis Tool (MAT) at The University of Waikato, and the Kiwi Research Information Service (KRIS) at the National Library of New Zealand. The tools have many similarities: they are convenient, online, on-demand services that harvest metadata using OAI-PMH; they were developed in response to feedback from repository administrators; and they both help pinpoint specific metadata errors as well as generating summary statistics. They also have significant differences: one is a dedicated tool wheres the other is part of a wider access tool; one gives a holistic view of the metadata whereas the other looks for specific problems; one seeks patterns in the data values whereas the other checks that those values conform to metadata standards. Both tools work in a complementary manner to existing Web-based administration tools. We have observed that discovery and correction of metadata errors can be quickly achieved by switching Web browser views from the analysis tool to the repository interface, and back. We summarize the findings from both tools' deployment into a checklist of requirements for metadata analysis tools

CHARACTERIZATION OF GLOMALIN, A GLYCOPROTEIN PRODUCED BY ARBUSCULAR MYCORRHIZAL FUNGI

Glomalin is an insoluble glycoprotein produced by hyphae of arbuscular mycorrhizal (AM) fungi. It is resistant to degradation and is found in large amounts in soil. Classical operationally defined extracts of soil organic matter include a large proteinaceous fraction. Therefore, clarification of glomalin as a separate fraction of extractable soil organic matter (SOM) is needed. Proof that glomalin accumulates over long periods of time has not been attempted. The overall hypothesis tested for this dissertation is that AM fungi are the source of an abundant, unique and important SOM component. The quantity of glomalin in soils was compared with particulate organic matter (POM), glomalin, humic acid (HA), and fulvic acid (FA) which were sequentially extracted from 5 8 undisturbed U.S. soils, aggregates and agriculturally managed soils that differed in tillage, crop rotation, and/or fertilizer amendment. Each fraction was extracted with the appropriate procedure: glomalin in pH 8.0 citrate at 121C, POM by floatation in NaCl solution, and HA and FA in NaOH with acidic separation. Organic matter fractions were evaluated for total and immunoreactive protein and/or gravimetric and C weights. Percentages of C, N and H were used to characterize each fraction. Glomalin structure was examined by proton nuclear magnetic resonance (1H NMR), removal of iron and separation of amino acid and carbohydrate groups. Glomalin accumulation in pot cultures was assessed at 14-week intervals in a 294-day experiment. Glomalin was unique in protein, C, H, and N contents compared with HA, FA and POM. Glomalin contributed ca. 20% of soil organic carbon. A recalcitrant glomalin pool was discovered that might have a functional role in water-stability of aggregates. 1H NMR spectra of glomalin were unique compared with HA spectra. Extracted glomalin had tightly bound iron, organic matter, amino acids and carbohydrates. Sustainable agricultural management practices reduced tillage, increased crop diversity, and reduced synthetic amendments increased aggregate stability of bulk soil and glomalin and POM concentrations. Glomalin production under controlled conditions was affected by irradiance. These results provide evidence that glomalin is a separate and unique fraction of SOM and is important in terrestrial carbon sequestration and sustainable agricultural practices
