To measure the effect of a short interpregnancy interval (IPI), along with other indicators routinely asked during pregnancy on later report of child maltreatment. We hypothesized that an IPI of \18 months was associated with increased risk of child maltreatment. This study was a secondary analysis of a linked population-based dataset from 2005 to 2007 in Florida. Data were derived from three sources: Birth Certificates, Healthy Start Prenatal Risk Screens, and the HomeSafeNet Database. Primary predictor variables were IPI, and mothers' evaluations of the timing of the pregnancy and perceptions of harm. Logistic regression analyses were used to estimate the odds of child maltreatment, adjusting for demographic and other known risk factors for maltreatment. The final study sample consisted of 85,258 multipara women-infant dyads with credible IPIs and with completed Healthy Start Prenatal Risk Screens. Seventeen percent of children had a report of child maltreatment in the first 5 years of life. An IPI of less than 18 months was associated with 18 % higher odds of maltreatment compared to an IPI of greater than 18 months (95 % CI 1.13, 1.23). Mothers' perception of harm and desire to be pregnant at a later time were also significantly associated with higher odds of maltreatment report (AOR = 2.43 95 % CI = 2.17, 2.71 and AOR = 1.18 95 % CI 1.13, 1.24, respectively). Ascertaining short IPI and asking pregnant and peripartum women about their perception of harm and desire for a longer birth spacing can alert obstetricians, family practitioners and pediatricians to potential child maltreatment.

Virtual schools are rising in popularity and presence. Unfortunately, there is a relative dearth of research related to teaching and learning in virtual schools. Although there are numerous handbooks addressing teaching online, there is little research on successful online teaching in the K-12 arena. Much of the existing research focused on teaching online is rooted in face-toface content, not focused on content areas, built upon a post-secondary audience, or fails to use data from the teachers themselves to triangulate findings. This ...

Limited data exists related to teaching and learning in K-12 virtual schools. This paper builds upon a recent study related to successful practices of K-12 online instructors. The paper describes the utilization of a survey built upon qualitatively derived best practices of K-12 online instructors and provides the opportunity to relate these practices to teacher's perceived professional development needs. Outcomes indicate that virtual school instructors identify online presence, diligent student monitoring and an enjoyment of technology ...

Recent evidence extends the health benefits of breastfeeding to include reduction of maternal body mass index (BMI) and childhood obesity. Since most women decide if they will breastfeed prior to pregnancy, it is important to understand, given the high population prevalence of obesity, if maternal underweight, overweight or obese status is associated with breastfeeding initiation. Population-based study. Florida resident birth certificate records. All live singleton births (2004)(2005)(2006)(2007)(2008)(2009), excluding observations that lacked the primary outcomes of maternal pre-pregnancy BMI and breastfeeding initiation (final sample of 1,161,949 unique observations). Odds of initiating breastfeeding, adjusted by maternal and infant factors, stratified by pre-pregnancy BMI, categorized as underweight, normal, overweight and obese. Adjusting for the known maternal factors associated with breastfeeding initiation, underweight and obese women were significantly less likely to initiate breastfeeding than women with normal BMI, (adjusted odds ratio 0.87, 95 % confidence interval 0.85-0.89 for underweight women; 0.84, 95 % CI 0.83-0.85 for obese women). The magnitude of these findings did not significantly vary by race or ethnicity. Medicaid status and adherence to the Institute of Medicine's 2009 pregnancy weight gain recommendations had only minor influences on breastfeeding initiation. Among adolescents, only underweight status predicted breastfeeding initiation; obesity did not. Underweight and obese women have significantly lower rates of breastfeeding initiation compared to women with normal pre-pregnancy BMI. Future studies need to address the health care, social, and physical barriers that interfere with breastfeeding initiation, especially in underweight and obese women, regardless of race, ethnicity or income.

Virtual schools are rising in popularity and presence. Unfortunately, there is a relative dearth of research related to teaching and learning in virtual schools. Although there are numerous handbooks addressing teaching online, there is little research on successful online teaching in the K-12 arena. Much of the existing research focused on teaching online is rooted in face-toface content, not focused on content areas, built upon a post-secondary audience, or fails to use data from the teachers themselves to triangulate findings. This article reports on a study of 16 virtual school teachers from the Michigan Virtual School (MVS). It reports on best-practices from the interviews conducted with MVS teachers; and also provides research triangulation for those practices. The paper concludes with implications for policy, research, and practice.

Limited data exists related to teaching and learning in K-12 virtual schools. This paper builds upon a recent study related to successful practices of K-12 online instructors. The paper describes the utilization of a survey built upon qualitatively derived best practices of K-12 online instructors and provides the opportunity to relate these practices to teacher's perceived professional development needs. Outcomes indicate that virtual school instructors identify online presence, diligent student monitoring and an enjoyment of technology among factors that contribute to virtual school instructor success. Instructors also identified face-to-face student mentors as a key component for success. Respondents felt that they would benefit from professional development focused on technological skills, contentbased technological integration and evaluative resources for online learners. The paper concludes with a call for additional research to refine and implement the assessment.

Purpose -The purpose of this paper is to engage in a thought experiment, exploring the use of Wikipedia or similar content-malleable systems for the review and dissemination of academic knowledge. Design/methodology/approach -By looking at other sources, the paper considers the current state of the academic peer-review process, discusses Wikipedia and reflects on dynamic content creation and management applications currently in use in academia. Findings -The traditional peer review process must be updated to match the rapid creation and diffusion of knowledge that characterises the 21st century. The Wikipedia concept is a potential model for more rapid and reliable dissemination of scholarly knowledge. The implications of such a concept would have a dramatic effect on the academic community. Originality/value -This paper promotes a radical idea for changing the methods by which academic knowledge is both constructed and disseminated.
