Foreign language (FL) and English as a Second Language (ESL) teaching present considerable challenges in the rural U.S. South. Local language ideologies, budgetary considerations, and challenges in other curricular areas (e.g., math and science) lead to marginalizing both FL and ESL in schools. This article examines the personal and professional trajectories of in-service language teachers in K–12 settings in the state of Mississippi to better understand how participants conceptualize their practice and their roles in schools. By analyzing the interview discourse of nine teachers, we found that both ESL and FL teachers positioned themselves against dominant ideologies and educational policies and constructed themselves as agents of change in the classroom, school, and community at large. This study contributes to the argument for integrating FL and ESL in rural areas, where both groups need support, and provides suggestions for ESL-FL teacher collaboration in rural schools. 相似文献

This article explores the historical roots of Ernest Boyer's impact on Christian higher education in the United States. Boyer's stints as a student at two Christian colleges (Messiah College in Pennsylvania and Greenville College in Illinois) and his first faculty and administrative posts at Upland College in California were significant influences in the development of his vision for the Christian college—a vision that led to greater legitimacy and credibility in the landscape of American higher education. Ernest Boyer's innovative, yet historic understanding of the distinctives of Christian higher education contributed to the successful accreditation process of nearly one hundred small, private institutions. 相似文献

Introduction
Sparse data are available about the effect of therapy methods on antibody levels in patients with liver failure. The aim of this study was to determine serum immunoglobulin concentrations in patients with chronic hepatic failure (CHF), acute- (ALF), or acute-on-chronic liver failure (ACLF) and to evaluate the impact of MARS treatment or liver transplantation (LT) on antibody levels.Materials and methods
We followed ten patients with ALF, twelve with ACLF and 18 with CHF. Eight patients with ALF and seven with ACLF underwent MARS therapy, whereas the rest received LT. 13 healthy volunteers served as controls. Serum antibody concentrations were measured using ELISA-technique.Results
Median serum levels of IgA, IgG and IgM were significantly increased in patients with CHF compared to ALF or controls (P < 0.02, P < 0.01, and P < 0.01). IgM and IgG concentrations were also significantly elevated in patients with CHF compared to ACLF (IgM, 3.7 vs. 1 g/L, P < 0.001; IgG, 8.7 vs. 3.1 g/L, P = 0.004). Immediately after LT a significant decrease of IgA (6.9 vs. 3.1 g/L, P = 0.004), IgG (8.7 vs. 5.1 g/L, P = 0.02) and IgM (3.7 vs. 1.8 g/L, P = 0.001) was detected in patients with CHF and antibody levels further decreased the days after LT reaching levels comparable to healthy individuals. MARS treatment had no apparent effect on the immunoglobulin profile in patients with ALF or ACLF.Conclusion
We provide evidence that LT reverses hypergammaglobulinemia in patients suffering from CHF within one day, which could be explained to a reconstituted hepatic antibody clearance, whereas MARS treatment has no immediate effect on immunoglobulin levels.Key words: antibodies, immunoglobulins, liver failure, liver transplantation, artificial liver support system, molecular adsorbent recirculating system 相似文献99.
