    ObjectiveIn this study, we sought to determine to what extent the abortion law in Ghana is reflective of public opinion.MethodsIn a cross‐sectional, community‐based survey, individuals in two fishing communities in Accra were interviewed about their beliefs on abortion between May and July 2016, and sociodemographic, attitudinal, and experience data were collected. Factors associated with the outcome variable (abortion is justified to save the life/health of the woman: Yes/No) were entered into a multivariate logistic regression.ResultsA total of 508 participants completed the survey. Thirty‐nine percent (n=198) of the sample agreed that abortion was justified to save the life/health of the woman, with no significant differences in this finding when controlling for understanding of the law, gender, marital status, or personal experience of abortion in multivariate analysis. Higher education (odds ratio [OR] 1.64 [P<0.001]) and older age (OR 1.28 [P<0.001]) are positively associated with abortion being justified to save life/health, while those who have had an experience of unwanted sex are less likely to believe that (OR 0.60 [P=0.029]).ConclusionThe participants held conservative views about the justification of abortion to save a woman’s life and/or health. Improving access to safe abortion services will require acknowledgment of the broader social and cultural context that may make accessing such services difficult.In a cross‐sectional survey, residents of urban Accra, Ghana, held relatively conservative views toward the justification of abortion.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151335/1/ijgo12927.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151335/2/ijgo12927_am.pd

    Scientists Want More Children

    Scholars partly attribute the low number of women in academic science to the impact of the science career on family life. Yet, the picture of how men and women in science – at different points in the career trajectory – compare in their perceptions of this impact is incomplete. In particular, we know little about the perceptions and experiences of junior and senior scientists at top universities, institutions that have a disproportionate influence on science, science policy, and the next generation of scientists. Here we show that having fewer children than wished as a result of the science career affects the life satisfaction of science faculty and indirectly affects career satisfaction, and that young scientists (graduate students and postdoctoral fellows) who have had fewer children than wished are more likely to plan to exit science entirely. We also show that the impact of science on family life is not just a woman's problem; the effect on life satisfaction of having fewer children than desired is more pronounced for male than female faculty, with life satisfaction strongly related to career satisfaction. And, in contrast to other research, gender differences among graduate students and postdoctoral fellows disappear. Family factors impede talented young scientists of both sexes from persisting to research positions in academic science. In an era when the global competitiveness of US science is at risk, it is concerning that a significant proportion of men and women trained in the select few spots available at top US research universities are considering leaving science and that such desires to leave are related to the impact of the science career on family life. Results from our study may inform university family leave policies for science departments as well as mentoring programs in the sciences

    Effect of tube diameter and capillary number on platelet margination and near-wall dynamics

    The effect of tube diameter DD and capillary number CaCa on platelet margination in blood flow at 37%\approx 37\% tube haematocrit is investigated. The system is modelled as three-dimensional suspension of deformable red blood cells and nearly rigid platelets using a combination of the lattice-Boltzmann, immersed boundary and finite element methods. Results show that margination is facilitated by a non-diffusive radial platelet transport. This effect is important near the edge of the cell-free layer, but it is only observed for Ca>0.2Ca > 0.2, when red blood cells are tank-treading rather than tumbling. It is also shown that platelet trapping in the cell-free layer is reversible for Ca0.2Ca \leq 0.2. Only for the smallest investigated tube (D=10μmD = 10 \mu\text{m}) margination is essentially independent of CaCa. Once platelets have reached the cell-free layer, they tend to slide rather than tumble. The tumbling rate is essentially independent of CaCa but increases with DD. Tumbling is suppressed by the strong confinement due to the relatively small cell-free layer thickness at 37%\approx 37\% tube haematocrit.Comment: 16 pages, 10 figure

    Psychometric Properties of the Parent and Teacher Versions of the Strengths and Difficulties Questionnaire for 4- to 12-Year-Olds: A Review

    Get PDF
    Since its development, the Strengths and Difficulties Questionnaire (SDQ) has been widely used in both research and practice. The SDQ screens for positive and negative psychological attributes. This review aims to provide an overview of the psychometric properties of the SDQ for 4- to 12-year-olds. Results from 48 studies (N = 131,223) on reliability and validity of the parent and teacher SDQ are summarized quantitatively and descriptively. Internal consistency, test–retest reliability, and inter-rater agreement are satisfactory for the parent and teacher versions. At subscale level, the reliability of the teacher version seemed stronger compared to that of the parent version. Concerning validity, 15 out of 18 studies confirmed the five-factor structure. Correlations with other measures of psychopathology as well as the screening ability of the SDQ are sufficient. This review shows that the psychometric properties of the SDQ are strong, particularly for the teacher version. For practice, this implies that the use of the SDQ as a screening instrument should be continued. Longitudinal research studies should investigate predictive validity. For both practice and research, we emphasize the use of a multi-informant approach

    <p>Abstract</p> <p>Background</p> <p>Previously, TP53 codon 72 polymorphisms have been implicated as risk factors for various cancers. A number of studies have conducted on the association of TP53 codon 72 polymorphisms with susceptibility to breast carcinoma and have yielded inconclusive results. The aim of the present study was to derive a more precise estimation of the relationship.</p> <p>Methods</p> <p>We conducted a search in the Medline, EMBASE, OVID, Sciencedirect, and Chinese National Knowledge Infrastructure (CNKI) without a language limitation, covering all papers published up to Jan 2009. The associated literature was acquired through deliberate searching and selected based on the established inclusion criteria for publications.</p> <p>Results</p> <p>A total of seventeen case-control studies, including 12226 cases and 10782 controls, met the included criteria and thus were selected. Ultimately, the relevant data were extracted and further analyzed using systematic meta-analyses. Overall, no associations of TP53 codon 72 polymorphisms with breast carcinoma were observed (for Arg/Arg vs Pro/Pro: OR = 1.20; 95%CI = 0.96–1.50; for dominant model: OR = 1.12; 95%CI = 0.96–1.32; for recessive model: OR = 1.13; 95%CI = 0.98–1.31). In the subgroup analysis by ethnicity, statistically similar results were obtained when the data were stratified as Asians, Caucasians and Africans.</p> <p>Conclusion</p> <p>Collectively, the results of the present study suggest that <it>TP53 codon 72 </it>polymorphisms might not be a low-penetrant risk factor for developing breast carcinoma.</p

    Malrotation with volvulus is one of the true surgical emergencies of childhood. Prompt radiological diagnosis is often paramount to achieving a good outcome. An understanding of the normal and anomalous development of the midgut provides a basis for understanding the pathophysiology and the clinical presentation of malrotation and malrotation complicated by volvulus. In this essay, the radiologic findings of malrotation and volvulus are reviewed and illustrated with particular attention to the child with equivocal imaging findings.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46708/1/247_2004_Article_1279.pd

    Pheromones and Other Semiochemicals for Monitoring Rare and Endangered Species

    As global biodiversity declines, biodiversity and conservation have become ever more important research topics. Research in chemical ecology for conservation purposes has not adapted to address this need. During the last 10-15 years, only a few insect pheromones have been developed for biodiversity and conservation studies, including the identification and application of pheromones specifically for population monitoring. These investigations, supplemented with our knowledge from decades of studying pest insects, demonstrate that monitoring with pheromones and other semiochemicals can be applied widely for conservation of rare and threatened insects. Here, I summarize ongoing conservation research, and outline potential applications of chemical ecology and pheromone-based monitoring to studies of insect biodiversity and conservation research. Such applications include monitoring of insect population dynamics and distribution changes, including delineation of current ranges, the tracking of range expansions and contractions, and determination of their underlying causes. Sensitive and selective monitoring systems can further elucidate the importance of insect dispersal and landscape movements for conservation. Pheromone-based monitoring of indicator species will also be useful in identifying biodiversity hotspots, and in characterizing general changes in biodiversity in response to landscape, climatic, or other environmental changes
