Outstanding Educational Performance Awards: Highlighting High Achieving Arkansas Schools, 2011

So, in this Arkansas Education Report (AER) we aim to highlight excellent performance and give our congratulations. To that end, we are happy to highlight many high performing schools around the state in our now-annual AER entitled the Outstanding Educational Performance Awards

Who Teaches Where? A Descriptive Analysis of Similarities and Differences between Teachers in Traditional and Charter Schools in Pulaski County, Arkansas

Using survey data collected from 893 public school teachers in Pulaski County, Arkansas, this study looks for differences in traditional public school teachers and charter school teachers on their (1) backgrounds and teacher characteristics; (2) motivations for entering the teaching profession; and (3) attitudes towards school and teaching. A multivariate analysis of the data revealed that few differences exist between the two groups of teachers on their backgrounds, teacher characteristics, and motivations to enter the teaching field. However, charter school teachers were found to be more likely to have positive attitudes towards school policy changes, a stronger professional commitment to student learning, and perceived themselves to have a higher level of personal agency within their schools than traditional public school teachers. These findings indicate that charter school teachers and traditional public school teachers in Pulaski County, Arkansas, on average, are not as different as previous research suggests. The differences found in previous studies could be attributed to the types of charter schools that were being studied, which attracted specific types of teachers. In contrast, the charter schools in this study did not have a common mission or recruitment technique and thus few systematic differences were found in teaching backgrounds and motivations for entering the teaching profession between the two groups of teachers. However, the differences found on teacher attitudes towards school and student learning seem to imply that charter schools do cultivate a different type of teacher, at least in Arkansas: one that is more flexible and sees himself or herself as more autonomous

An Exploration of Marginal Attachment to the Australian Labour Market

One of the key factors that affects the extent to which changes in labour demand affect other macroeconomic variables, such as wage inflation, is the degree of matching between potential employees and available jobs. The pool of potential employees is usually measured as the pool of unemployed workers. However, this ignores an important group of people who are not officially unemployed, but do represent potential labour supply the marginally attached workforce, which can be broadly defined as the people who are not currently in the labour force, but want to work and are available to take up employment. The aim of this paper is to examine the extent to which the labour market behaviour of marginally attached workers is similar to that of the unemployed. We use longitudinal data from the Survey of Employment and Unemployment Patterns (SEUP), which provides detailed information on the characteristics of individuals as well as their labour market experiences, to compare dynamic behaviour across labour market groups, for example, the probability of moving into employment. We find that in some respects the dynamic behaviour of the marginally attached is similar to that of the unemployed, but in others it is quite different. Accordingly, the most appropriate measure of labour supply depends on the policy question, and consequently a range of measures should be considered.dynamic behaviour; effective labour supply; marginal attachment; transition probability; unemployment

Effects of Rumination on Problem-Solving, Mood and Confidence in Post-natal

Previous studies have sought to investigate the effects of rumination and distraction on social problem-solving, mood and confidence of dysphoric and depressed individuals. The current study is aimed at extending this literature by examining the effects of rumination on parental problem-solving, mood and problem-solving confidence among dysphoric post-natal women. Fifty-nine post-natal women took part in the study and were allocated to either the dysphoric or control group based upon the Edinburgh Post-natal Depression Scale (Cox, Holden & Sagovsky, 1987). Women were asked to complete measures of mood, confidence and four problem-solving tasks following a rumination or distraction mood induction. Results indicated that dysphoric post-natal women induced to ruminate showed poorer problemsolving and lower mood than dysphoric women induced to distract and non-dysphoric women induced to distract or ruminate. No significant differences were seen in reported confidence levels for dysphoric post-natal women induced to ruminate than dysphoric women induced to distract and non-dysphoric women induced to distract or ruminate. Consideration is given to the clinical implications of these findings as well as the limitations and possibilities for future research

Second-line antiretroviral therapy in resource-limited settings: the experience of Médecins Sans Frontières

OBJECTIVES: To describe the use of second-line protease-inhibitor regimens in Médecins Sans Frontières HIV programmes, and determine switch rates, clinical outcomes, and factors associated with survival. DESIGN/METHODS: We used patient data from 62 Médecins Sans Frontières programmes and included all antiretroviral therapy-naive adults (> 15 years) at the start of antiretroviral therapy and switched to a protease inhibitor-containing regimen with at least one nucleoside reverse transcriptase inhibitor change after more than 6 months of nonnucleoside reverse transcriptase inhibitor first-line use. Cumulative switch rates and survival curves were estimated using Kaplan-Meier methods, and mortality predictors were investigated using Poisson regression. RESULTS: Of 48,338 adults followed on antiretroviral therapy, 370 switched to a second-line regimen after a median of 20 months (switch rate 4.8/1000 person-years). Median CD4 cell count at switch was 99 cells/microl (interquartile ratio 39-200; n = 244). A lopinavir/ritonavir-based regimen was given to 51% of patients and nelfinavir-based regimen to 43%; 29% changed one nucleoside reverse transcriptase inhibitor and 71% changed two nucleoside reverse transcriptase inhibitors. Median follow-up on second-line antiretroviral therapy was 8 months, and probability of remaining in care at 12 months was 0.86. Median CD4 gains were 90 at 6 months and 135 at 12 months. Death rates were higher in patients in World Health Organization stage 4 at antiretroviral therapy initiation and in those with CD4 nadir count less than 50 cells/microl. CONCLUSION: The rate of switch to second-line treatment in antiretroviral therapy-naive adults on non-nucleoside reverse transcriptase inhibitor-based first-line antiretroviral therapy was relatively low, with good early outcomes observed in protease inhibitor-based second-line regimens. Severe immunosuppression was associated with increased mortality on second-line treatment

Prognostic limitations of donor t cell chimerism after myeloablative allogeneic stem cell transplantation for acute myeloid leukemia and myelodysplastic syndromes

Donor T cell chimerism is associated with relapse outcomes after allogeneic stem cell transplantation (alloSCT) for acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). However, measures of statistical association do not adequately assess the performance of a prognostic biomarker, which is best characterized by its sensitivity and specificity for the chosen outcome. We analyzed donor T cell chimerism results at day 100 (D100chim) after myeloablative alloSCT for AML or MDS in 103 patients and determined its sensitivity and specificity for relapse-free survival at 6 months (RFS6) and 12 months (RFS12) post-alloSCT. The area under the receiver operating characteristic curve for RFS6 was .68, demonstrating only modest utility as a predictive biomarker, although this was greater than RFS12 at .62. Using a D100chim threshold of 65%, the specificity for RFS6 was 96.6%; however, sensitivity was poor at 26.7%. This equated to a negative predictive value of 88.5% and positive predictive value of 57.1%. Changing the threshold for D100chim to 75% or 85% modestly improved the sensitivity of D100chim for RFS6; however, this was at the expense of specificity. D100chim is specific but lacks sensitivity as a prognostic biomarker of early RFS after myeloablative alloSCT for AML or MDS. Caution is required when using D100chim to guide treatment decisions including immunologic manipulation, which may expose patients to unwarranted graft-versus-host disease
