Online video instruction on hand expression of colostrum in pregnancy is an effective educational tool

The use of antenatal colostrum expression in the weeks prior to birth may help improve long-term breastfeeding, but few large-scale studies exist. Typically, antenatal colostrum expression instruction relies on face-to-face education, making large interventions costly. We aimed to determine whether an expert online instructional video can improve knowledge and confidence around antenatal colostrum expressing. Pregnant women were asked to complete a questionnaire pre- and post-watching the instructional video online. Ninety five pregnant women completed both pre- and post-questionnaires. Total antenatal colostrum expression knowledge scores improved after watching the video, from a mean of 3.05 ± 1.70 correct out of a maximum of 7, to 6.32 ± 0.76 (p \u3c 0.001). Self-reported confidence around hand expressing in pregnancy also improved from an average ranking of not confident (2.56 ± 1.17, out of a possible 5) to confident (4.32 ± 0.80, p \u3c 0.001). Almost all women (98%) reported that they would recommend the video to a friend or family member if antenatal colostrum expression was suggested by their healthcare provider. Findings suggest that the use of an online expert video is an acceptable and effective way to educate pregnant women in antenatal colostrum expression

Child Custody Outcomes in Cases Involving Parental Alienation and Abuse Allegations

Arguably the most troubling aspect of justice system response to intimate partner violence is custody courts\u27 failure to protect children when mothers allege the father is abusive. Family courts\u27 errors in assessing adult and child abuse, and punitive responses to abuse allegations, have been widely documented. A significant contributor to these errors is the pseudo-scientific theory of parental alienation (PA). Originally termed parental alienation syndrome (PAS), the theory suggests that when mothers allege that a child is not safe with the father, they are doing so illegitimately, to alienate the child from the father. PA labeling often results in dismissal of women\u27s and children\u27s reports of abuse, and sometimes trumps even expert child abuse evaluations. PAS was explicitly based on negative stereotypes of mothers and has been widely discredited. The term parental alienation – while treated as distinct - is still widely used in ways that are virtually identical to PAS. Nonetheless, because PA is nominally gender neutral (and not called a scientific syndrome), it continues to have substantial credibility in court. The first goal of this project was to ascertain whether empirical evidence indicates that parental alienation is, like PAS, gender-biased in practice and outcome. Second, the study sought to explore outcomes in custody/abuse litigation by gender and by differing types of abuse. Analysis of over 2000 court opinions confirms that courts are skeptical of mothers’ claims of abuse by fathers; this skepticism is greatest when mothers claim child abuse. The findings also confirm that fathers’ cross-claims of parental alienation increase (virtually doubling) courts’ rejection of mothers’ abuse claims, and mothers’ losses of custody to the father accused of abuse. In comparing court responses when fathers accuse mothers of abuse, a significant gender difference is identified. Finally, the findings indicate that where Guardians Ad Litem or custody evaluators are appointed, unfavorable outcomes for mothers and gender differences are increased. The study relies solely on electronically available published opinions in child custody cases. It has produced an invaluable database identifying 10 years of published cases involving alienation, abuse and custody, while coding parties’ claims and defenses, outcomes, and other key factors by gender and parental status

The trouble with Harman and Lorandos’s attempted refutation of the Meier et al. Family court study

Harman and Lorandos assert that they have produced a study analyzing custody cases involving alienation allegations, which “disconfirms” the findings from our study of family court out- comes in cases involving abuse and alienation. In addition to pointing out the authors’ misrepresentation and mis-reporting of some of their findings, this Response details a series of profound flaws in their study’s design, dataset construction and variable coding, interpretations and analytic approach, as well as a series of statistical errors. The statistical analyses demonstrate that Harman and Lorandos’s five findings of a gender bias in favor of fathers are not supported by their data; the only statistically significant findings that persist after re-analysis of the correct data are consistent with the Meier et al. study. These pervasive design and methodological errors undermine both the appearance and assertion of rigor in their approach; these problems and the foundational differences in their dataset from our own disqualify their study from serving as any kind of credible test or disconfirmation of our study

Harman and Lorandos’ False Critique of Meier et al.’s Family Court Study

Jennifer Harman and Demosthenes Lorandos purport to have identified numerous methodological flaws in our 2019 study of family court outcomes in cases involving abuse and alienation allegations (“FCO study”; Meier et al., 2019). At least half of the supposed flaws they itemized relate to one claim - that they were unable to access our methods and data. They treat the claimed lack of public access as evidence that our study is unreliable, while speculating about other potential flaws. Yet we note - and they acknowledge - that most of the methodological information they sought was in fact available before publication of their article. This article responds to and refutes Harman and Lorandos’ exaggerated and unfounded condemnation of our study. In addition to pointing out that the claimed lack of information would not be a methodological flaw even if true, we explain that their other criticisms are speculative, incorrect, or insignificant. We appreciate this opportunity to clarify that the important findings of the FCO study are valid and should be taken seriously by the courts and those interested in the fairness and safety of custody decisions when there are allegations of abuse and alienation

Global Carbon Budget 2022

Accurate assessment of anthropogenic carbon dioxide (CO$_2$) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate is critical to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe and synthesize data sets and methodologies to quantify the five major components of the global carbon budget and their uncertainties. Fossil CO$_2$ emissions (E$_{FOS}$) are based on energy statistics and cement production data, while emissions from land-use change (E$_{LUC}$), mainly deforestation, are based on land use and land-use change data and bookkeeping models. Atmospheric CO$_2$ concentration is measured directly, and its growth rate (G$_{ATM}$) is computed from the annual changes in concentration. The ocean CO$_2$ sink (S$_{OCEAN}$) is estimated with global ocean biogeochemistry models and observation-based data products. The terrestrial CO$_2$ sink (S$_{LAND}$) is estimated with dynamic global vegetation models. The resulting carbon budget imbalance (B$_{IM}$), the difference between the estimated total emissions and the estimated changes in the atmosphere, ocean, and terrestrial biosphere, is a measure of imperfect data and understanding of the contemporary carbon cycle. All uncertainties are reported as ±1σ. For the year 2021, E$_{FOS}$ increased by 5.1 % relative to 2020, with fossil emissions at 10.1 ± 0.5 GtC yr$^{−1}$ (9.9 ± 0.5 GtC yr$^{−1}$ when the cement carbonation sink is included), and E$_{LUC}$ was 1.1 ± 0.7 GtC yr$^{−1}$, for a total anthropogenic CO$_2$ emission (including the cement carbonation sink) of 10.9 ± 0.8 GtC yr$^{−1}$ (40.0 ± 2.9 GtCO$_2$). Also, for 2021, G$_{ATM}$ was 5.2 ± 0.2 GtC yr$^{−1}$ (2.5 ± 0.1 ppm yr$^{−1}$), S$_{OCEAN}$ was 2.9  ± 0.4 GtC yr$^{−1}$, and S$_{LAND}$ was 3.5 ± 0.9 GtC yr$^{−1}$, with a B$_{IM}$ of −0.6 GtC yr$^{−1}$ (i.e. the total estimated sources were too low or sinks were too high). The global atmospheric CO$_2$ concentration averaged over 2021 reached 414.71 ± 0.1 ppm. Preliminary data for 2022 suggest an increase in E$_{FOS}$ relative to 2021 of +1.0 % (0.1 % to 1.9 %) globally and atmospheric CO$_2$ concentration reaching 417.2 ppm, more than 50 % above pre-industrial levels (around 278 ppm). Overall, the mean and trend in the components of the global carbon budget are consistently estimated over the period 1959–2021, but discrepancies of up to 1 GtC yr$^{−1}$ persist for the representation of annual to semi-decadal variability in CO$_2$ fluxes. Comparison of estimates from multiple approaches and observations shows (1) a persistent large uncertainty in the estimate of land-use change emissions, (2) a low agreement between the different methods on the magnitude of the land CO$_2$ flux in the northern extratropics, and (3) a discrepancy between the different methods on the strength of the ocean sink over the last decade. This living data update documents changes in the methods and data sets used in this new global carbon budget and the progress in understanding of the global carbon cycle compared with previous publications of this data set.

Diving into the vertical dimension of elasmobranch movement ecology

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements

Galactic Core-Collapse Supernovae at IceCube: “Fire Drill” Data Challenges and follow-up

The next Galactic core-collapse supernova (CCSN) presents a once-in-a-lifetime opportunity to make astrophysical measurements using neutrinos, gravitational waves, and electromagnetic radiation. CCSNe local to the Milky Way are extremely rare, so it is paramount that detectors are prepared to observe the signal when it arrives. The IceCube Neutrino Observatory, a gigaton water Cherenkov detector below the South Pole, is sensitive to the burst of neutrinos released by a Galactic CCSN at a level >10σ. This burst of neutrinos precedes optical emission by hours to days, enabling neutrinos to serve as an early warning for follow-up observation. IceCube\u27s detection capabilities make it a cornerstone of the global network of neutrino detectors monitoring for Galactic CCSNe, the SuperNova Early Warning System (SNEWS 2.0). In this contribution, we describe IceCube\u27s sensitivity to Galactic CCSNe and strategies for operational readiness, including "fire drill" data challenges. We also discuss coordination with SNEWS 2.0

All-Energy Search for Solar Atmospheric Neutrinos with IceCube

The interaction of cosmic rays with the solar atmosphere generates a secondary flux of mesons that decay into photons and neutrinos – the so-called solar atmospheric flux. Although the gamma-ray component of this flux has been observed in Fermi-LAT and HAWC Observatory data, the neutrino component remains undetected. The energy distribution of those neutrinos follows a soft spectrum that extends from the GeV to the multi-TeV range, making large Cherenkov neutrino telescopes a suitable for probing this flux. In this contribution, we will discuss current progress of a search for the solar neutrino flux by the IceCube Neutrino Observatory using all available data since 2011. Compared to the previous analysis which considered only high-energy muon neutrino tracks, we will additionally consider events produced by all flavors of neutrinos down to GeV-scale energies. These new events should improve our analysis sensitivity since the flux falls quickly with energy. Determining the magnitude of the neutrino flux is essential, since it is an irreducible background to indirect solar dark matter searches
