Bombing Gaza isn't fighting sexual violence
As the human catastrophe in Gaza deepens, Israel and its allies are mobilizing evidence of sexual violence committed by members of Hamas and other Palestinian militant groups on October 7 to justify continued military action. When the Security Council failed to pass a resolution demanding a ceasefire on December 8, Israel government spokesperson Eylon Levy tweeted: “Thank you to the United States of America for vetoing a UN Security Council resolution designed to keep Hamas’ rapist regime in power.” In the wake of its case at the International Court of Justice accusing Israel of genocide Levy accused South Africa of complicity with a “rapist regime.

Arboviral disease outbreaks in the Pacific Islands countries and areas, 2014 to 2020: a systematic literature and document review
Arthropod-borne diseases pose a significant public health threat, accounting for greater than 17% of infectious disease cases and 1 million deaths annually. Across Pacific Island countries and areas (PICs), outbreaks of dengue, chikungunya, and Zika are increasing in frequency and scale. Data about arbovirus outbreaks are incomplete, with reports sporadic, delayed, and often based solely on syndromic surveillance. We undertook a systematic review of published and grey literature and contacted relevant regional authorities to collect information about arboviral activity affecting PICs between October 2014 and June 2020. Our literature search identified 1176 unique peer-reviewed articles that were reduced to 25 relevant publications when screened. Our grey literature search identified 873 sources. Collectively, these data reported 104 unique outbreaks, including 72 dengue outbreaks affecting 19 (out of 22) PICs, 14 chikungunya outbreaks affecting 11 PICs, and 18 Zika outbreaks affecting 14 PICs. Our review is the most complete account of arboviral outbreaks to affect PICs since comparable work was published in 2014. It highlights the continued elevated level of arboviral activity across the Pacific and inconsistencies in how information about outbreaks is reported and recorded. It demonstrates the importance of a One-Health approach and the role that improved communication and reporting between different governments and sectors play in understanding the emergence, circulation, and transboundary risks posed by arboviral diseases
Pulsations in the atmosphere of the roAp star HD 24712 II. Theoretical models
We discuss pulsations of the rapidly oscillating Ap (roAp) star HD 24712 (HR
1217) based on nonadiabatic analyses taking into account the effect of dipole
magnetic fields. We have found that all the pulsation modes appropriate for HD
24712 are damped; i.e., the kappa-mechanism excitation in the hydrogen
ionization layers is not strong enough to excite high-order p-modes with
periods consistent with observed ones, all of which are found to be above the
acoustic cut-off frequencies of our models.
The main (2.721 mHz) and the highest (2.806 mHz) frequencies are matched with
modified and modes, respectively. The large frequency separation
(Hz) is reproduced by models which lay within the error box of
HD 24712 on the HR diagram. The nearly equally spaced frequencies of HD 24712
indicate the small frequency separation to be as small as Hz.
However, the small separation derived from theoretical and 2 modes are
found to be larger than Hz. The problem of equal spacings could be
resolved by assuming that the spacings correspond to pairs of and
modes. The amplitude distribution on the stellar surface is strongly affected
by the magnetic field resulting in the predominant concentration at the polar
regions.
Amplitudes and phases of radial-velocity variations for various spectral
lines are converted to relations of amplitude/phase versus optical depth in the
atmosphere. Oscillation phase delays gradually outward in the outermost layers
indicating the presence of waves propagating outward. The phase changes steeply
around , which supports a relation having a small
temperature inversion there.Comment: 11 pages, 13 figures, accepted for publication in MNRA
Exploring experiences and impact of the COVID-19 pandemic on young racially minoritised people in the United Kingdom: A qualitative study
Within high-income-countries, the COVID-19 pandemic has disproportionately impacted people from racially minoritised backgrounds. There has been significant research interrogating the disparate impact of the virus, and recently, interest in the long-term implications of the global crisis on young people's mental health and wellbeing. However, less work explores the experiences of young people from racialised backgrounds as they navigate the pandemic, and the specific consequences this has for their mental health. Forty young people (age 16-25) from Black, mixed and other minority backgrounds and living in London, participated in consecutive focus group discussions over a two-month period, to explore the impact of the pandemic on their lives and emotional wellbeing. Thematic analysis identified seven thematic categories describing the impact of the pandemic, indicating: deepening of existing socioeconomic and emotional challenges; efforts to navigate racism and difference within the response; and survival strategies drawing on communal and individual resources. Young people also articulated visions for a future public health response which addressed gaps in current strategies. Findings point to the need to contextualize public health responses to the pandemic in line with the lived experiences of racialised young people. We specifically note the importance of long-term culturally and socio-politically relevant support interventions. Implications for policy and practice are discussed
Black Hole Masses and Star Formation Rates of z >1 Dust Obscured Galaxies (DOGs): Results from Keck OSIRIS Integral Field Spectroscopy
We have obtained high spatial resolution Keck OSIRIS integral field
spectroscopy of four z~1.5 ultra-luminous infrared galaxies that exhibit broad
H-alpha emission lines indicative of strong AGN activity. The observations were
made with the Keck laser guide star adaptive optics system giving a spatial
resolution of 0.1", or <1 kpc at these redshifts. These high spatial resolution
observations help to spatially separate the extended narrow-line regions ---
possibly powered by star formation --- from the nuclear regions, which may be
powered by both star formation and AGN activity. There is no evidence for
extended, rotating gas disks in these four galaxies. Assuming dust correction
factors as high as A(H-alpha)=4.8 mag, the observations suggest lower limits on
the black hole masses of (1 - 9) x 10^8 solar masses, and star formation rates
<100 solar masses per year. The black hole masses and star formation rates of
the sample galaxies appear low in comparison to other high-z galaxies with
similar host luminosities. We explore possible explanations for these
observations including, host galaxy fading, black hole growth, and the shut
down of star formation.Comment: Accepted for publication in the Astronomical Journal. 12 pages, 6

Development and Validation of the Vending Evaluation for Nutrient-Density (VEND)ing Audit
Background: This paper describes the development and validation of the Vending Evaluation for Nutrient-Density (VEND)ing audit to comprehensively evaluate vended products based upon healthfulness, price and promotion, and machine accessibility. Methods: A novel vending nutrient-density score was created to determine the healthfulness of vended snack/beverage products. Field tested in United States colleges, VENDing audit (Σnutrient-density + 10 x % healthy products) and Support sub-scores (price + promotion + accessibility) were calculated for snack/beverage machines. Higher scores indicate more healthful vending options and supports for choosing healthfully. Nutrition Environment Measures Survey-Vending (NEMS-V) was used to validate the nutrient-density score for a sub-sample of machines. Sensitivity and specificity were computed by comparing the number of healthy snacks/beverages determined by NEMS-V and the VENDing nutrient-density scores. Results: Researchers conducted the VENDing audit on 228 snack/beverage vending machines at 9 universities within the United States and used both VENDing and NEMS-V on 33 snack and 52 beverage vending machines. Mean VENDing audit scores were 4.5 ± 2.0 (2.6, 3.4) and 2.6 ± 2.0 (0, 12) for snack/beverage machines, respectively. The number of products considered healthy assessed with both the VENDing nutrient-density scores and the NEMS-V were positively correlated for beverages (r = 0.687, p \u3c 0.001) and snacks (r = 0.366, p \u3c 0.05). The sensitivity was excellent for beverages (0.83) and moderate for snacks (0.69); while the specificity was moderate for both beverages (0.66) and snacks (0.50). Conclusions: The VENDing audit uses unique, valid, an
