Born in the USA: Exceptionalism in Maternity Care Organisation Among High-Income Countries
In lay terms, childbirth is regarded as a purely biological event: what is more natural than birth and death? On the other hand, social scientists have long understood that \'natural\' events are socially structured. In the case of birth, sociologists have examined the social and cultural shaping of its timing, outcome, and the organization of care throughout the perinatal period. Continuing in this tradition, we examine the peculiar social design of birth in the United States of America, contrasting this design with the ways birth is organised in Europe. We begin by showing how several key characteristics of the US health care system â including its inherent social inequality, its high level of medicalisation, and the substantial influence of private medical practice and insurance companies â influence the organization of maternity care there. We then explore how cultural characteristics of American society â its emphasis on individuality, the influence of moral conservatism in US politics, and the ease with which ordinary people take court action (the so-called \'litigation culture\') â shape the delivery of care at birth. We conclude with a consideration of the implications of US maternity care exceptionalism for comparative sociological analysis.Pregnancy, Comparative Studies, Exceptionalism, United States, Midwifery, Maternity Care, Birth
Social Service Professional or Market Expert? Maternity Care Relations under Neoliberal Healthcare Reform
Recent developments in the organization and practice of healthcare, driven by the introduction of (quasi-) markets and privatization, are altering traditional forms of professionalism found in high- and middle-income countries.
Yet there remains debate about whether these neoliberal trends are universal or country specific, and whether they have any effect (positive or negative) on health service delivery. This article develops a comparative analysis that focuses on changes in maternity service systems in four countries in Northern Europe and the Americas with primarily publicly financed healthcare systems: the UK, Finland, Chile and Canada. The article begins with a discussion of the continuum of professional forms found in the post-Second World War period and their relationship to different kinds of welfare e states. It then focuses on the impact of recent neoliberal reforms on the ideological projects of the medical and allied health professions in the four case examples. The results show that variation across time and place is mainly the result of structural/ economic factors and that various forms of professional discourses are the result of the public/private ways that healthcare systems are organized. The article concludes with suggestions for further comparative sociological research
Learning from health care in other countries: the prospect of comparative research
It is widely accepted that policy-makers (in Nepal and elsewhere) can learn valuable lessons from the way other countries run their health and social services. We highlight some of the specific contributions the discipline of sociology can make to cross-national comparative research in the public health field. Sociologists call attention to often unnoticed social and cultural factors that influence the way national reproductive health care systems are created and operated. In this paper we address questions such as: âWhy do these health services appear to be operating successfully in one country, but not another?â; âWhat is it in one country that makes a particular public health intervention successful and how is the cultural context different in a neighbouring country?â The key examples in this paper focus on maternity care and sex education in the Netherlands and the UK, as examples to highlight the power of cross-national research. Our key messages are: a) Cross-national comparative research can help us to understand the design and running of health services in one country, say Nepal, by learning from a comparison with other countries, for example Sri Lanka or India. b) Cultural factors unique to a country affect the way that reproductive health care systems operate. c) Therefore, we need to understand why and how services work in a certain cultural context before we start trying to implement them in another cultural context
The Dilemmas of Laissez-Faire Population Policy in Capitalist Societies: When the Invisible Hand Controls Reproduction
Education Aspirations and Barriers to Achievement for StreetâInvolved Youth in Victoria, Canada
Much of the literature on streetâinvolved youth focuses on their deficits, including their high risk of withdrawing before completing high school, which is often interpreted as a rejection of formal education. Missing from the literature is an understanding of streetâinvolved youthâs educational aspirations. We employed thematic analysis of qualitative data from inâperson interviews with a purposive sample of streetâinvolved youth (N = 69) residing in one city in Canada, who were partly or fully disengaged from school at the time of the interview. We asked the youth to talk about their opinions of formal education, its importance for young people, whether learning was important for them, and whether they imagined returning to school/continuing with school. We discovered that the majority of youth had a positive view of school/formal education and stated they liked learning new things and recognized the benefits of continuing/completing their education. At the same time, the youth identified material hardship and other barriers to achieving their educational goals. We discuss these findings in light of the relevant literature and make policy recommendations to improve educational success for youth struggling with poverty and homelessness in Canada
Aestivation of the African Malaria Mosquito, Anopheles gambiae in the Sahel
The African malaria mosquito, Anopheles gambiae, inhabits diverse environments including dry savannas, where surface waters required for larval development are absent for 4â8 months per year. Under such conditions, An. gambiae virtually disappears. Whether populations survive the long dry season by aestivation (a dormant state promoting extended longevity during the summer) or are reestablished by migrants from distant locations where larval sites persist has remained an enigma for over 60 years. Resolving this question is important, because fragile dry season populations may be more susceptible to control. Here, we show unequivocally that An. gambiae aestivates based on a demographic study and a mark releaseârecapture experiment spanning the period from the end of one wet season to the beginning of the next. During the dry season, An. gambiae was barely detectable in Sahelian villages of Mali. Five days after the first rain, before a new generation of adults could be produced, mosquito abundance surged 10-fold, implying that most mosquitoes were concealed locally until the rain. Four days after the first rain, a marked female An. gambiae s.s. was recaptured. Initially captured, marked, and released at the end of the previous wet season, she has survived the 7-month-long dry season. These results provide evidence that An. gambiae persists throughout the dry season by aestivation and open new questions for mosquito and parasite research. Improved malaria control by targeting aestivating mosquitoes using existing or novel strategies may be possible
Cluster and MMS simultaneous observations of magnetosheath high speed jets and their impact on the magnetopause
When the supersonic solar wind encounters the Earth's magnetosphere a shock, called bow shock, is formed and the plasma is decelerated and thermalized in the magnetosheath downstream from the shock. Sometimes, however, due to discontinuities in the solar wind, bow shock ripples or ionized dust clouds carried by the solar wind, high speed jets (HSJs) are observed in the magnetosheath. These HSJs have typically a Vx component larger than 200 km sâ1 and their dynamic pressure can be a few times the solar wind dynamic pressure. They are typically observed downstream from the quasi-parallel bow shock and have a typical size around one Earth radius (RE) in XGSE. We use a conjunction of Cluster and MMS, crossing simultaneously the magnetopause, to study the characteristics of these HSJs and their impact on the magnetopause. Over 1 h 15 min interval in the magnetosheath, Cluster observed 21 HSJs. During the same period, MMS observed 12 HSJs and entered the magnetosphere several times. A jet was observed simultaneously by both MMS and Cluster and it is very likely that they were two distinct HSJs. This shows that HSJs are not localized into small regions but could span a region larger than 10 RE, especially when the quasi-parallel shock is covering the entire dayside magnetosphere under radial IMF. During this period, two and six magnetopause crossings were observed, respectively, on Cluster and MMS with a significant angle between the observation and the expected normal deduced from models. The angles observed range between from 11° up to 114°. One inbound magnetopause crossing observed by Cluster (magnetopause moving out at 142 km sâ1) was observed simultaneous to an outbound magnetopause crossing observed by MMS (magnetopause moving in at â83 km sâ1), showing that the magnetopause can have multiple local indentation places, most likely independent from each other. Under the continuous impacts of HSJs, the magnetopause is deformed significantly and can even move in opposite directions at different places. It can therefore not be considered as a smooth surface anymore but more as surface full of local indents. Four dust impacts were observed on MMS, although not at the time when HSJs are observed, showing that dust clouds would have been present during the observations. No dust cloud in the form of Interplanetary Field Enhancements was however observed in the solar wind which may exclude large clouds of dust as a cause of HSJs. Radial IMF and AlfvĂ©n Mach number above 10 would fulfill the criteria for the creation of bow shock ripples and the subsequent crossing of HSJs in the magnetosheath.publishedVersio
FEELnc : a tool for long non-coding RNA annotation and its application to the dog transcriptome
Whole transcriptome sequencing (RNA-seq) has become a standard for cataloguing and monitoring RNA populations. One of the main bottlenecks, however, is to correctly identify the different classes of RNAs among the plethora of reconstructed transcripts, particularly those that will be translated (mRNAs) from the class of long non-coding RNAs (lncRNAs). Here, we present FEELnc (FlExible Extraction of LncRNAs), an alignment-free program that accurately annotates lncRNAs based on a Random Forest model trained with general features such as multi k-mer frequencies and relaxed open reading frames. Benchmarking versus five state-of-the-art tools shows that FEELnc achieves similar or better classification performance on GENCODE and NONCODE data sets. The program also provides specific modules that enable the user to fine-tune classification accuracy, to formalize the annotation of lncRNA classes and to identify lncRNAs even in the absence of a training set of non-coding RNAs. We used FEELnc on a real data set comprising 20 canine RNA-seq samples produced by the European LUPA consortium to substantially expand the canine genome annotation to include 10 374 novel lncRNAs and 58 640 mRNA transcripts. FEELnc moves beyond conventional coding potential classifiers by providing a standardized and complete solution for annotating lncRNAs and is freely available at https://github.com/tderrien/FEELnc.Peer reviewe
A population of gamma-ray emitting globular clusters seen with the Fermi Large Area Telescope
Globular clusters with their large populations of millisecond pulsars (MSPs)
are believed to be potential emitters of high-energy gamma-ray emission. Our
goal is to constrain the millisecond pulsar populations in globular clusters
from analysis of gamma-ray observations. We use 546 days of continuous
sky-survey observations obtained with the Large Area Telescope aboard the Fermi
Gamma-ray Space Telescope to study the gamma-ray emission towards 13 globular
clusters. Steady point-like high-energy gamma-ray emission has been
significantly detected towards 8 globular clusters. Five of them (47 Tucanae,
Omega Cen, NGC 6388, Terzan 5, and M 28) show hard spectral power indices and clear evidence for an exponential cut-off in the range
1.0-2.6 GeV, which is the characteristic signature of magnetospheric emission
from MSPs. Three of them (M 62, NGC 6440 and NGC 6652) also show hard spectral
indices , however the presence of an exponential cut-off
can not be unambiguously established. Three of them (Omega Cen, NGC 6388, NGC
6652) have no known radio or X-ray MSPs yet still exhibit MSP spectral
properties. From the observed gamma-ray luminosities, we estimate the total
number of MSPs that is expected to be present in these globular clusters. We
show that our estimates of the MSP population correlate with the stellar
encounter rate and we estimate 2600-4700 MSPs in Galactic globular clusters,
commensurate with previous estimates. The observation of high-energy gamma-ray
emission from a globular cluster thus provides a reliable independent method to
assess their millisecond pulsar populations that can be used to make
constraints on the original neutron star X-ray binary population, essential for
understanding the importance of binary systems in slowing the inevitable core
collapse of globular clusters.Comment: Accepted for publication in A&A. Corresponding authors: J.
