    This study uses longitudinal data from school children in Dunedin, New Zealand, to evaluate impacts of COVID-19 lockdown measures on changes in body mass (BMI, kg/m ). Impacts are assessed using two non-mutually exclusive hypotheses. The "structured days" hypothesis holds that children tend to alter sleep patterns, reduce activity and increase snacking when not in structured environments. The bidirectional hypothesis proposes that over-weight or obese children are predisposed to further gains in unstructured settings. Juveniles and adolescents (n = 95, 60% female) were recruited from Dunedin schools. Repeated measures analyses assessed variation in intra-individual change in BMI during four periods: P1 (before summer break), P2 (during summer break), P3 (during the COVID-19 lockdown), and P4 (after the lockdown ended). The model also examined if these changes were influenced by participants' sex or body size early in the first period assessed using log-transformed BMI, log-transformed weight, height, or lower leg length. Repeated measures analyses of per month gains in BMI (kg/m ) during the four periods revealed consistent period (p ≤ .001), period by sex (p ≤ .010), and period by body size (p ≤ .001) interactions across all four body size proxies. Both sexes experienced the greatest gains during the lockdown (P3), but differed in response to their summer break (P2). Results are mostly consistent with the "structured days" hypothesis, but challenge the bidirectional hypothesis as defined. Further research better characterizing risks of gains in adiposity are needed. [Abstract copyright: © 2023 The Authors. American Journal of Human Biology published by Wiley Periodicals LLC.

    Reconstructing Disturbances and Their Biogeochemical Consequences over Multiple Timescales

    Ongoing changes in disturbance regimes are predicted to cause acute changes in ecosystem structure and function in the coming decades, but many aspects of these predictions are uncertain. A key challenge is to improve the predictability of postdisturbance biogeochemical trajectories at the ecosystem level. Ecosystem ecologists and paleoecologists have generated complementary data sets about disturbance (type, severity, frequency) and ecosystem response (net primary productivity, nutrient cycling) spanning decadal to millennial timescales. Here, we take the first steps toward a full integration of these data sets by reviewing how disturbances are reconstructed using dendrochronological and sedimentary archives and by summarizing the conceptual frameworks for carbon, nitrogen, and hydrologic responses to disturbances. Key research priorities include further development of paleoecological techniques that reconstruct both disturbances and terrestrial ecosystem dynamics. In addition, mechanistic detail from disturbance experiments, long-term observations, and chronosequences can help increase the understanding of ecosystem resilienc

    Finishing the euchromatic sequence of the human genome

    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Towards Engagement: Exploring the Prospects for an Integrated Anthropology of Disability

    No full text
    Impairment and disability are fundamental human experiences across cultures, yet disability remains curiously under-studied and under-theorized within anthropology, particularly within physical anthropology and archaeology. Why is this the case and how might this change? This paper critically examines anthropology’s varying detachment from and engagement with disability studies up to the present. It is suggested that a holistic approach which integrates data and insights from archaeology, physical anthropology, and sociocultural anthropology would offer the means for an important and distinctly anthropological contribution to the study of disability in the past and present. Lessons are taken from previous anthropological work on women/gender and Indigenous peoples. It is argued that a focus on theoretically-situated bodies, increased inclusion of people with disabilities, and a demonstrated relevance to current disability issues will be essential aspects of an integrated ‘anthropology of disability’

    Exploring Ethical and Methodological Issues in Internet-Based Research with Adolescents

    No full text
    Internet-based research is a relatively new and growing field that presents a number of ethical challenges regarding privacy, confidentiality, and informed consent. In light of a study examining discussions regarding the human papillomavirus (HPV) vaccine on a publicly viewable Internet message board among primarily American, Australian, and Canadian female adolescents and young adults, the author discusses the methodological and ethical concerns surrounding Internet-based qualitative research with youth. The author first provides some contextual background about the study and issues surrounding the HPV vaccine. She describes her methods of data collection and analysis and provides a summary of the results. The author then explores a number of ethical issues that arise in Internet-based research and examines her own ethical decision-making as informed by existing discussions and guidelines in this area

    The Social Geography of Diphtheria Mortality in Hamilton

    This Hamilton, Ontario today displays stark socioeconomic disparities in health which pattern along north/south lines within the city. Diphtheria provides a useful lens for examining the historical nature of these socioeconomic disparities. Data were collected from death registrations for the period 1900 to 1921 and 321 deaths were mapped in ArcMap. Diphtheria mortality rates were higher in the north overall; however, no difference was found for the 5–16 year age group (school age). Higher mortality in children under age five in the north due to factors associated with low SES may explain the differing rates. These results demonstrate the social inequalities in health that existed in early-twentieth century Hamilton and their geographic dimension.La ville d’Hamilton en Ontario présente aujourd’hui de fortes disparités socioéconomiques en termes de santé qui se moulent à la division nord/sud de la ville. La diphtérie nous permet d’examiner la nature historique de ces disparités. Des données recueillies de l’enregistrement des décès depuis 1900 jusqu’à 1921 ont permis l’analyse de 321 décès dans ArcMap. Malgré le fait que le taux de mortalité de la diphtérie était plus élevé au nord en général, aucune différence n’a été repérée dans le groupe d’âge de 5 à 16 ans. Dans le nord, le taux de mortalité plus élevé chez les enfants de moins de 5 ans serait alors lié aux facteurs associés avec une faible position socioéconomique. Ces résultats démontrent la dimension géographique de l’inégalité sociale en matière de santé qui existait à Hamilton au début du 20e siècle

    Learning from the past & present: social science implications for COVID-19 immunity-based documentation

    Abstract In responding to the widespread impacts of the COVID-19 pandemic, countries have proposed and implemented documentation policies that confer varying levels of freedoms or restrictions (e.g., ability to travel) based on individuals’ infection status or potential immunity. Most discussions around immunity- or infection-based documentation policies have focused on scientific plausibility, economic benefit, and challenges relating to ethics and equity. As COVID-19 vaccines are rolled out, attention has turned to confirmation of immunity and how documentation such as vaccine certificates or immunity passports can be implemented. However, the contextual inequities and local variabilities interacting with COVID-19 related documentation policies hinder a one-size-fits-all approach. In this Comment, we argue that social science perspectives can and should provide additional insight into these issues, through a diverse range of current and historical examples. This would enable policymakers and researchers to better understand and mitigate current and longer-term differential impacts of COVID-19 immunity-based documentation policies in different contexts. Furthermore, social science research methods can uniquely provide feedback to inform adjustments to policy implementation in real-time and help to document how these policy measures are felt differently across communities, populations, and countries, potentially for years to come. This Comment, updated as of 15 August 2021, combines precedents established in historical disease outbreaks and current experiences with COVID-19 immunity-based documentation policies to highlight valuable lessons and an acute need for further social science research which should inform effective and context-appropriate future public health policy and action

    The introduction and distribution history of the common myna (<i>Acridotheres tristis</i>) in New Zealand

    No full text
    Throughout history, human movements have been a mechanism by which species are introduced to new environments. Although these introductions may sometimes be unintended, they have often occurred through organised effort and led to successful establishment outside a species’ native range. The common myna (Acridotheres tristis) is an invasive bird species that has successfully established globally, including on New Zealand’s North Island. To better understand the establishment of this invasive species, historical records of the myna’s introduction and subsequent distribution were compiled and analysed. We determine that mynas were introduced into New Zealand repeatedly between the 1860s and 1880s, originating from stock acclimatised in Australia with strong links to Melbourne. Additionally, we track the changing distribution of the myna across New Zealand, allowing us to create a detailed timeline. Our findings are discussed in the context of the motivations behind myna introduction, and public response to their introduction and spread.</p
