The Perspectives of African American Women: Their Pregnancy Experience and Their Babiesâ Birth Outcomes
The health disparity surrounding infant mortality has been a challenge for public health professionals for the past two decades. Today African American babies continue to die at a rate two times higher than the nationâs average rate. The purpose of this study was to explore African American mothersâ perspectives on their pregnancy experience and their babiesâ birth outcomes, as a way to provide suggestions for current efforts and interventions being used to lower the rate of infant mortality in the African American population. This study examined fifteen peer reviewed articles that shared the perspectives of African American women who were either pregnant, had children or were of childbearing age. The articles were analyzed and placed into groups to come up with common themes that were present throughout the fifteen articles. The themes that were developed from the selected articles included: a) support & empowerment, b) knowledge & resources, and c) access to quality care. There is overlap between all three themes which suggested that all three themes work together in providing an ideal pregnancy. Even with all three themes working together it was recognized that the impact of each theme could vary depending on the mothersâ background. Therefore, it is important to acknowledge different value systems when developing interventions to address the issue of infant mortality rather than applying one intervention to all
Do Trading Derivatives Classification Affect Bank Holding Companyâs Earnings Volatility And Firm Value?
This study examines the differential impact of bank holding companies (BHCs) that consistently report trading gains (successful speculators) and those that consistently report no gain or trading losses (unsuccessful speculators) on earnings volatility and firm value. Under Accounting Standards Codification (ASC) 815 (previously SFAS 133- Accounting for Derivative Instruments and Hedging Activities), all gains/losses related to trading derivatives are recognized in current earnings; whereas, gains/losses on hedging derivatives are netted with changes in the fair value of the underlying asset/liability with only the ineffective portion of the hedge being reported in current earnings. Given differential accounting recognition and underlying risk factors, we expect and find that current period trading gains/losses lead to greater earnings volatility; however, the relationship becomes insignificant when BHCs consistently report trading gains (successful speculators) or no gains and trading losses (unsuccessful speculation). Further we find that successful speculation is significantly negatively associated with firm value, which implies that market participants perceive trading positions held by BHCs as high-risk investments regardless of the outcome of the trading exposure. The findings of this study should be useful to business professionals, bank regulators, and accounting standard setters in determining the economic impact of current accounting standards on bank performance, investors in evaluating the costs and benefits of bankâs derivative risk management policies, and accounting academics in evaluating the impact of current accounting regulation on bank derivative use
Rapid evolution with generation overlap: the double-edged effect of dormancy
In life histories with generation overlap, selection that acts differently on different life-stages can produce reservoirs of genetic variation, for example, in long-lived iteroparous adults or long-lived dormant propagules. Such reservoirs provide âmigration from the pastâ to the current population, and depending on the trend of environmental change, they have the potential either to slow adaptive evolution or accelerate it by re-introducing genotypes not affected by recent selection (e.g., through storage effect in a fluctuating environment). That is, the effect of generation overlap is a âdouble-edged sword,â with each edge cutting in a different direction. Here, we use sexual (quantitative trait) and asexual (clonal) models to explore the effects of generation overlap on adaptive evolution in a fluctuating environment, either with or without a trend in the mean environment state. Our analyses show that when environmental stochasticity scaled by strength of selection is intermediate and when the trend in mean environment is slow, intermediate values of generation overlap can maximize the rate of response to selection and minimize the adaptation lag between the trait mean and the environmental trend. Otherwise, increased generation overlap results in smaller selection response and larger adaptation lag. In the former case, low generation overlap results in low heritable trait variance, while high generation overlap increases the âmigration loadâ from the past. Therefore, to understand the importance of rapid evolution and eco-evolutionary dynamics in the wild for organisms with overlapping generations, we need to understand the interaction of generation overlap, environmental stochasticity, and strength of selection

Comparison of DMSP cross-track ion drifts and SuperDARN line-of-sight velocities
Cross-track ion drifts measured by the DMSP satellites are compared with line-of-sight SuperDARN HF velocities in approximately the same directions. Good overall agreement is found for a data set comprising of 209 satellite passes over the field of view of nine SuperDARN radars in both the Northern and Southern Hemispheres. The slope of the best linear fit line relating the SuperDARN and DMSP velocities is of the order of 0.7 with a tendency for SuperDARN velocities to be smaller. The agreement implies that the satellite and radar data can be merged into a common set provided that spatial and temporal variations of the velocity as measured by both instruments are smooth.<br><br> <b>Keywords.</b> Ionosphere (Ionospheric irregularities; Plasma convection; Auroral ionosphere

Testing nowcasts of the ionospheric convection from the expanding and contracting polar cap model
The expanding/contracting polar cap (ECPC) model, or the time-dependent Dungey cycle, provides a theoretical framework for understanding solar wind-magnetosphere-ionosphere coupling. The ECPC describes the relationship between magnetopause reconnection and substorm growth phase, magnetotail reconnection and substorm expansion phase, associated changes in auroral morphology, and ionospheric convective motions. Despite the many successes of the model, there has yet to be a rigorous test of the predictions or nowcasts made regarding ionospheric convection, which remains a final hurdle for the validation of the ECPC. In this study we undertake a comparison of ionospheric convection, as measured in situ by ion drift meters on board DMSP (Defense Meteorological Satellite Program) satellites and from the ground by SuperDARN (Super Dual Auroral Radar Network), with motions nowcasted by a theoretical model. The model is coupled to measurements of changes in the size of the polar cap made using global auroral imagery from the IMAGE FUV (Imager for Magnetopause to Aurora Global Exploration Far Ultraviolet) instrument, as well as the dayside reconnection rate, estimated using the OMNI data set. The results show that we can largely nowcast the magnitudes of ionospheric convection flows using the context of our understanding of magnetic reconnection at the magnetopause and in the magnetotail

How prisoners and their partners experience the maintenance of their relationship during a prison sentence
Research shows that intimate relationships, and their maintenance via prison visits, have a positive impact on factors associated with prisoner wellâbeing and reduced likelihood of recidivism. It is therefore in the interest of corrections, government, and wider society to enable prisoners to maintain healthy relationships with their family and intimate partners throughout their prison sentence. Despite this evidence, little is known about how prisoners experience the maintenance of a significant intimate relationship in prison. This study aims to explore heterosexual couples' experiences in maintaining their wellâestablished intimate relationships, while the male partner is incarcerated. Four main themes were identified: how they experienced âhaving a special connectionâ that they were motivated to maintain; âcoping with challenges and threatsâ to that connection; âdeveloping reciprocal behavioursâ to meet those challenges; and âmaintaining a belief in the future.â Implications for how the relational context of rehabilitation can best be supported is considered
