Women’s Experiences with Prenatal Care: A Mixed-Methods Study Exploring the Influence of the Social Determinants of Health
Background & Purpose: Racial and ethnic disparities pervade birth outcomes in the United States and the state of Connecticut. While Connecticut’s infant mortality rate is less than the national average, rates for the state’s Black/African American and Hispanic/Latino communities exceed it. This study explored how prenatal care in Connecticut may be enhanced to address these disparities.
Methods: In spring 2013, seven focus groups and two semi-structured interviews were conducted (n=47). Participants also self-administered brief surveys. Recruited by local service providers, participants were 18 or older, pregnant and/or in the first year post-partum at the time. Most self-identified as non-white.
Results: Even when care was perceived as strong quality, participants perceived a lack of patient-centeredness. Participants knew the importance of prenatal care and actively prioritized it even when experiencing challenges accessing healthcare services or barriers to broader conditions needed to be healthy. Participants also reported experiencing discrimination in healthcare.
Conclusions & Implications: The women esteemed providers’ clinical advice, but felt unheard in their prenatal care experiences and faced structural challenges which may be addressed by changing institutional policies and procedures
Vector chiral order in frustrated spin chains
By means of a numerical analysis using a non-Abelian symmetry realization of
the density matrix renormalization group, we study the behavior of vector
chirality correlations in isotropic frustrated chains of spin S=1 and S=1/2,
subject to a strong external magnetic field. It is shown that the field induces
a phase with spontaneously broken chiral symmetry, in line with earlier
theoretical predictions. We present results on the field dependence of the
order parameter and the critical exponents.Comment: 8 pages, 9 figure
Damned if you do and damned if you don't: The (Re)production of larger breasts as ideal in criticisms of breast surgery
This is the author accepted manuscript. The final version is available from Taylor & Francis via the DOI in this record.In contemporary Western societies women are often thought to have overcome inequality, become autonomous and resistant to social pressures, and in so doing gained the freedoms to make their own choices. However, this ‘post-feminist sensibility’ can arguably be seen as a double-bind as some types of ‘choices’ cannot always be recognised as freely chosen if they are taken as an indication of failing to resist social (appearance) pressures. We argue that one such example is the ‘choice’ to have cosmetic breast surgery, a practice that has received both criticism and celebration from different feminist angles. In this paper we analyse how women who have had breast augmentation are constructed by readers of an internet blog in which they are largely vilified and pathologised for not valuing their ‘natural’ (yet ‘deficient’) breasts. We demonstrate how the same discursive constructions that appear to value women’s ‘natural’ bodies simultaneously (re)produce the conditions in which women may feel the need to have breast augmentation
Morphological and molecular variability in some Iranian almond genotypes and related Prunus species and their potentials for rootstock breeding
41 Pag., 6 Fig., 5 Tabl. The definitive version is available at: http://www.sciencedirect.com/science/journal/03044238In this study, in order to know the variability for a rootstock breeding program genetic diversity and
relationships among 55 Iranian almond genotypes and seven related Prunus species were investigated.
Morphological and molecular analyses were used. Principal component analysis showed that three components
explained 67.6% of the total morphological variation for the first year and 68.06% for the second
year of the study. Leaf traits were predominant in the first component and contributed most of the total
variation. Leaf length and width, as well as, leaf area were highly correlated with each other and correlated
to vigor. Also a negative correlation was found between leaf length/width ratio and vigor. Ward’s
method was used to construct cluster from morphological data which allocated individuals into their
respective species. Out of 100 pre-screened RAPD primers, 16 with reproducible bands and maximum
polymorphism were selected. Two-hundred and sixty bands were scored of which 250 of them were polymorphic.
Average value of polymorphism per primer was 95.81% and maximum value for polymorphism
(100%) was obtained from TIBMBA-14, TIBMBA-17, TIBMBB-05, TIBMBB-08, TIBMBD-09, and TIBMBD-10.
On the other hand, the minimum value was obtained from TIBMBB-16 (86%). Primer TIBMBB-5 gave the
maximum number of bands (25 fragments) and the minimum obtained from TIBMBE-18 (11 fragments).
Genetic similarity based on Jaccard’s coefficient ranged from 0.28 to 0.79 with an average of 0.53. Molecular
analysis revealed a high degree of separation among samples regarding their geographical origin.
Correlation between two approaches was low (R =−0.38). High molecular and morphological variability
indicated that this collection includes rich and valuable plant materials for almond rootstock breeding.We are grateful for the financial supports provided by the Center of Excellence for stone fruits root stock breeding program of the University of Tehran.Peer reviewe
Measurement of Transverse Polarization of Electrons Emitted in Free Neutron Decay
The final analysis of the experiment determining both components of the
transverse polarization of electrons (, )
emitted in the -decay of polarized, free neutrons is presented. The
T-odd, P-odd correlation coefficient quantifying ,
perpendicular to the neutron polarization and electron momentum, was found to
be 0.0040.005. This value is consistent with time reversal
invariance, and significantly improves both earlier result and limits on the
relative strength of imaginary scalar couplings in the weak interaction. The
value obtained for the correlation coefficient associated with
, 0.0670.004, agrees with the Standard Model
expectation, providing an important sensitivity test of the experimental setup.
The present result sets constraints on the imaginary part of scalar and tensor
couplings in weak interaction. Implications for parameters of the leptoquark
exchange model and minimal supersymmetric model (MSSM) with R-parity violation
are discussed
Parameter Estimation and Quantitative Parametric Linkage Analysis with GENEHUNTER-QMOD
Objective: We present a parametric method for linkage analysis of quantitative phenotypes. The method provides a test for linkage as well as an estimate of different phenotype parameters. We have implemented our new method in the program GENEHUNTER-QMOD and evaluated its properties by performing simulations. Methods: The phenotype is modeled as a normally distributed variable, with a separate distribution for each genotype. Parameter estimates are obtained by maximizing the LOD score over the normal distribution parameters with a gradient-based optimization called PGRAD method. Results: The PGRAD method has lower power to detect linkage than the variance components analysis (VCA) in case of a normal distribution and small pedigrees. However, it outperforms the VCA and Haseman-Elston regression for extended pedigrees, nonrandomly ascertained data and non-normally distributed phenotypes. Here, the higher power even goes along with conservativeness, while the VCA has an inflated type I error. Parameter estimation tends to underestimate residual variances but performs better for expectation values of the phenotype distributions. Conclusion: With GENEHUNTER-QMOD, a powerful new tool is provided to explicitly model quantitative phenotypes in the context of linkage analysis.
