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 – including its inherent social inequality, its high level of medicalisation, and the substantial influence of private medical practice and insurance companies – influence the organization of maternity care there. We then explore how cultural characteristics of American society – 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\') – 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
The Dutch Obstetrical System: Vanguard of the Future in Maternity Care
The German poet Heinrich Heine is reported to have said, “When the world comes to an end, I shall go to Holland, for everything there happens
fi fty years later.” For some, this Dutch “quaintness” explains the unusual system of obstetric care found in the Netherlands, a system where nearly one-third of births occur at home and where midwives have a degree of
professional independence unrivaled by midwives in any other country.
Heine’s observation about the Netherlands suggests that the unique Dutch way of birth is a vestige from a bygone era—a credible conclusion if you believe that humans are helpless in the face of technology. But the stubborn persistence of midwifery and home birth in the Netherlands, in spite of the declaration of medical professionals elsewhere that midwife-attended birth at home is a dangerous anachronism, forces us to conclude that Dutch obstetrics can be the vanguard of the future
Threats to freshwater fisheries in the United States: perspectives and investments of state fisheries administrators and Agricultural Experiment Station directors
Freshwater fisheries provide human benefits (e.g., food, recreation) but are increasingly threatened by climate change, invasive species, and other stressors. Our purpose was to survey fisheries administrators from state fisheries agencies and Agricultural Experiment Stations (AESs) about their perceptions of, and resource investment toward threats to freshwater fisheries in the United States. Our rationale for studying these two types of fisheries administrators simultaneously was to inform state fisheries professionals about the fisheries relevance of AESs, elevate the profile of fisheries within AESs, and promote mutually beneficial state agency–AES partnerships. Survey respondents generally agreed that recreational, socioeconomic, and ecological services of fisheries were more important than nutritional and commercial benefits. The greatest perceived fisheries threats were water quality/quantity impairment, land‐use change, and invasive species—but, interestingly, not climate change. State fisheries agencies invested more personnel and finances into issues rated as less important but more controllable (e.g., fish production, habitat management) than issues rated as more important but larger in scale and more difficult to control (e.g., water quality/quantity, invasive species). Our research underscores the importance of ensuring that state agencies can address long‐term, socio‐ecologically critical management issues (e.g., climate change) amid budgetary constraints. We call for state agencies to collaborate with new partners (e.g., AESs) to mitigate fisheries threats by expanding fisheries management to more fully encompass terrestrial and human systems; promoting receptiveness to novel research/management ideas; actively predicting, monitoring, and planning for future stressors; and enhancing fisheries social‐ecological resilience
Spatial-genetic structuring in a red-breasted merganser (Mergus serrator) colony in the Canadian Maritimes
The clustering of kin is widespread across the animal kingdom and two of the primary mechanisms underlying the formation of these patterns in adult kin are (1) philopatric tendencies and (2) actively maintained kin associations. Using polymorphic microsatellites, we had set out to characterize the level of genetic-spatial organization within a colony of female red-breasted mergansers (Mergus serrator) breeding on a series of small barrier islands in Kouchibouguac National Park, NB, Canada. Additionally, using nesting data from this colony, we explored possibilities for the existence of kin associations and/or cooperative interactions between these individuals; specifically in the form of the synchronization of breeding activities (i.e., incubation initiation). Our results include: (1) the detection of broad-scale genetic structuring over the entire colony, as females nesting on separate islands were to some extent genetically distinct; (2) the detection of weak, yet significant, positive spatial autocorrelation of kin at the fine scale, but only in the more densely-populated areas of this colony; and (3) the synchrony of breeding activities among proximally nesting females, apart from any factors of relatedness. While these results confirm the existence of genetic-spatial organization within this colony, the underlying mechanisms producing such a signal are inconclusive
NMR Characterizations of the Ice Binding Surface of an Antifreeze Protein
Antifreeze protein (AFP) has a unique function of reducing solution freezing temperature to protect organisms from ice damage. However, its functional mechanism is not well understood. An intriguing question concerning AFP function is how the high selectivity for ice ligand is achieved in the presence of free water of much higher concentration which likely imposes a large kinetic barrier for protein-ice recognition. In this study, we explore this question by investigating the property of the ice binding surface of an antifreeze protein using NMR spectroscopy. An investigation of the temperature gradient of amide proton chemical shift and its correlation with chemical shift deviation from random coil was performed for CfAFP-501, a hyperactive insect AFP. A good correlation between the two parameters was observed for one of the two Thr rows on the ice binding surface. A significant temperature-dependent protein-solvent interaction is found to be the most probable origin for this correlation, which is consistent with a scenario of hydrophobic hydration on the ice binding surface. In accordance with this finding, rotational correlation time analyses combined with relaxation dispersion measurements reveals a weak dimer formation through ice binding surface at room temperature and a population shift of dimer to monomer at low temperature, suggesting hydrophobic effect involved in dimer formation and hence hydrophobic hydration on the ice binding surface of the protein. Our finding of hydrophobic hydration on the ice binding surface provides a test for existing simulation studies. The occurrence of hydrophobic hydration on the ice binding surface is likely unnecessary for enhancing protein-ice binding affinity which is achieved by a tight H-bonding network. Subsequently, we speculate that the hydrophobic hydration occurring on the ice binding surface plays a role in facilitating protein-ice recognition by lowering the kinetic barrier as suggested by some simulation studies
Enabling global clinical collaborations on identifiable patient data: The Minerva Initiative
The clinical utility of computational phenotyping for both genetic and rare diseases is increasingly appreciated; however, its true potential is yet to be fully realized. Alongside the growing clinical and research availability of sequencing technologies, precise deep and scalable phenotyping is required to serve unmet need in genetic and rare diseases. To improve the lives of individuals affected with rare diseases through deep phenotyping, global big data interrogation is necessary to aid our understanding of disease biology, assist diagnosis, and develop targeted treatment strategies. This includes the application of cutting-edge machine learning methods to image data. As with most digital tools employed in health care, there are ethical and data governance challenges associated with using identifiable personal image data. There are also risks with failing to deliver on the patient benefits of these new technologies, the biggest of which is posed by data siloing. The Minerva Initiative has been designed to enable the public good of deep phenotyping while mitigating these ethical risks. Its open structure, enabling collaboration and data sharing between individuals, clinicians, researchers and private enterprise, is key for delivering precision public health
