    Get PDF
    A study of nine forms of wild geese in three arctic areas and in Illinois. Following an introduction on the use of own feathers for lining the nest, and earlier work on this behaviour, author deals with the occurrence and characteristics of the incubation patch in geese; and evidence of former incubation in wintering birds. The relation of the patch to egg laying and to hormonal factor as well as its value in age determination are discussed

    The Kill of Wild Geese by the Natives of the Hudson-James Bay Region

    Get PDF
    The economic plight of Indians and Eskimos in the Hudson-James Bay area is partly dependent on the numbers of wild geese nesting in or migrating through their territory. The information presented on kills indicates that the number taken by native hunters is within a safe limit of what the nesting populations of that area can withstand. Expansion of wintering grounds and inaccessibility of breeding grounds assure that wild geese will continue to be an important source of food for the northern natives

    An Inferred Sex Differential in Copper Metabolism in Ross' Geese (Anser rossii): Biogeochemical and Physiological Considerations

    Get PDF
    The geology and the levels of various minerals in the nutrient chain of the ecosystems of the breeding grounds of most populations of wild geese are distinctive. Hence minerals that become incorporated in the keratin of the primary feathers grown on the breeding grounds can be used as biological tracers to determine origins of migrants. Hormones indirectly affect the levels of some minerals in the feather keratin. Estrogen is presumed to account for higher levels of copper found in the primary feathers of adult female, as compared with adult male, Ross' geese (Anser rossii)

    The status of the research on muon colliders is discussed and plans are outlined for future theoretical and experimental studies. Besides continued work on the parameters of a 3-4 and 0.5 TeV center-of-mass (CoM) energy collider, many studies are now concentrating on a machine near 0.1 TeV (CoM) that could be a factory for the s-channel production of Higgs particles. We discuss the research on the various components in such muon colliders, starting from the proton accelerator needed to generate pions from a heavy-Z target and proceeding through the phase rotation and decay (π→μνμ\pi \to \mu \nu_{\mu}) channel, muon cooling, acceleration, storage in a collider ring and the collider detector. We also present theoretical and experimental R & D plans for the next several years that should lead to a better understanding of the design and feasibility issues for all of the components. This report is an update of the progress on the R & D since the Feasibility Study of Muon Colliders presented at the Snowmass'96 Workshop [R. B. Palmer, A. Sessler and A. Tollestrup, Proceedings of the 1996 DPF/DPB Summer Study on High-Energy Physics (Stanford Linear Accelerator Center, Menlo Park, CA, 1997)].Comment: 95 pages, 75 figures.

    The Problem of Experience in the Study of Organizations

    Full text link
    This paper deals with the fact that we cannot experience large organizations directly, in the same way as we can experience individuals or small groups, and that this non-experientiability has certain implications for our scientific theories of organizations. Whereas a science is animated by a constructive interplay of theory concepts and experience concepts, the study of organizations has been confined to theory concepts alone. Implications of this analysis for developing a science of organizations are considered.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68303/2/10.1177_017084069301400102.pd

    Management of obesity across women's life course : FIGO best practice advice

    Get PDF
    Obesity is a chronic, progressive, relapsing, and treatable multifactorial, neurobehavioral disease. According to the World Health Organization, obesity affects 15% of women and has long-term effects on women's health. The focus of care in patients with obesity should be on optimizing health outcomes rather than on weight loss. Appropriate and common language, considering cultural sensitivity and trauma-informed care, is needed to discuss obesity. Pregnancy is a time of significant physiological change. Pre-, ante-, and postpartum clinical encounters provide opportunities for health optimization for parents with obesity in terms of, but not limited to, fertility and breastfeeding. Pre-existing conditions may also be identified and managed. Beyond pregnancy, women with obesity are at an increased risk for gastrointestinal and liver diseases, impaired kidney function, obstructive sleep apnea, and venous thromboembolism. Gynecological and reproductive health of women living with obesity cannot be dismissed, with accommodations needed for preventive health screenings and consideration of increased risk for gynecologic malignancies. Mental wellness, specifically depression, should be screened and managed appropriately. Obesity is a complex condition and is increasing in prevalence with failure of public health interventions to achieve significant decrease. Future research efforts should focus on interprofessional care and discovering effective interventions for health optimization.The Canadian Institutes for Health Research and the Crohns and Colitis Foundation of Canada, the European Commission Horizon 2020, National Health and Medical Research Council of Australia, Health Research Board Ireland, Al Qasimi Foundation, University of Sharjah, AstraZeneca, Bayer, Novo Nordisk, Pfizer, Tricida Inc., Phillips Health Care, Mead Johnson (China), Diabetes Ireland, Thermo Fischer, Roche, and Perkin Elmer and payment from Homburg and Partner.

    Using FIGO nutrition checklist counselling in pregnancy : a review to support healthcare professionals

    Get PDF
    The period before and during pregnancy is increasingly recognized as an important stage for addressing malnutrition. This can help to reduce the risk of noncommunicable diseases in mothers and passage of risk to their infants. The FIGO Nutrition Checklist is a tool designed to address these issues. The checklist contains questions on specific dietary requirements, body mass index, diet quality, and micronutrients. Through answering these questions, awareness is generated, potential risks are identified, and information is collected that can inform health-promoting conversations between women and their healthcare professionals. The tool can be used across a range of health settings, regions, and life stages. The aim of this review is to summarize nutritional recommendations related to the FIGO Nutrition Checklist to support healthcare providers using it in practice. Included is a selection of global dietary recommendations for each of the components of the checklist and practical insights from countries that have used it. Implementation of the FIGO Nutrition Checklist will help identify potential nutritional deficiencies in women so that they can be addressed by healthcare providers. This has potential longstanding benefits for mothers and their children, across generations.Open access funding provided by IReL.http:// wileyonlinelibrary.com/journal/ijgoam2024Obstetrics and GynaecologySDG-02:Zero HungerSDG-03:Good heatlh and well-bein

    Hypertensive disorders of pregnancy and long-term cardiovascular health : FIGO best practice advice

    Get PDF
    Hypertensive disorders of pregnancy (HDP) are the most common causes of maternal and perinatal morbidity and mortality. They are responsible for 16% of maternal deaths in high-income countries and approximately 25% in low-and middle-income countries. The impact of HDP can be lifelong as they are a recognized risk factor for future cardiovascular disease. During pregnancy, the cardiovascular system undergoes significant adaptive changes that ensure adequate uteroplacental blood flow and exchange of oxygen and nutrients to nurture and accommodate the developing fetus. Failure to achieve normal cardiovascular adaptation is associated with the development of HDP. Hemodynamic alterations in women with a history of HDP can persist for years and predispose to long-term cardiovascular morbidity and mortality. Therefore, pregnancy and the postpartum period are an opportunity to identify women with underlying, often unrecognized, cardiovascular risk factors. It is important to develop strategies with lifestyle and therapeutic interventions to reduce the risk of future cardiovascular disease in those who have a history of HDP.http://wileyonlinelibrary.com/journal/ijgoam2024Obstetrics and GynaecologySDG-03:Good heatlh and well-bein

    Pregnancy as an opportunity to prevent type 2 diabetes mellitus : FIGO best practice advice

    Get PDF
    Gestational diabetes (GDM) impacts approximately 17 million pregnancies worldwide. Women with a history of GDM have an 8–10- fold higher risk of developing type 2 diabetes and a 2-fold higher risk of developing cardiovascular disease (CVD) compared with women without prior GDM. Although it is possible to prevent and/or delay progression of GDM to type 2 diabetes, this is not widely undertaken. Considering the increasing global rates of type 2 diabetes and CVD in women, it is essential to utilize pregnancy as an opportunity to identify women at risk and initiate preventive intervention. This article reviews existing clinical guidelines for postpartum identification and management of women with previous GDM and identifies key recommendations for the prevention and/or delayed progression to type 2 diabetes for global clinical practice.A Chinese University of Hong Kong Faculty of Medicine Faculty Postdoctoral Fellowship and support from a Croucher Foundation Senior Medical Research Fellowship.
