Background COVID-19 has disproportionately impacted low-income immigrant communities. There is concern that the current uptake of COVID-19 vaccines is suboptimal and that this may be contributing to ...COVID-19 inequities. However, little is known about the acceptability of COVID-19 vaccines among immigrants in the U.S. Our goal was to gauge COVID-19 vaccine intentions among Brazilian immigrant women living in the U.S. Methods We conducted an online survey between July and August 2020 offered in Portuguese and English languages among a convenience sample of Brazilian immigrant women ages 18 years and older. Women were recruited through online advertisements by community-based organizations and social media groups to complete a survey that assessed intention to get a COVID-19 vaccine, attitudes toward vaccines, and perceptions about the pandemic. Results Of the total sample (N = 353), most (70.8%) indicated they intended to get a COVID-19 vaccine. In bivariate analyses, vaccine intentions were significantly associated with perceptions about the severity of the pandemic, trusted sources of health information, and the number of years lived in the U.S. Multinomial logistic regression models revealed that those who did not intend to be vaccinated had lived a longer time in the U.S. (OR: -0.12 95% CI: -0.19, -0.05), perceived the pandemic to be a minor issue (OR: 1.52, 95% CI: 0.62, 2.42), and trusted information from social networks (OR: -1.94, 95% CI: -3.25, -0.63) or private news sources (OR: -1.71, 95% CI: -2.78, -0.63). Conclusions While most women reported they would get a COVID-19 vaccine, efforts to reach those who may be hesitant should target those who have lived in the U.S. for longer periods of time and do not perceive the pandemic to be a major crisis. Healthcare providers may be particularly suited to deliver this information given high levels of trust.

Sea otters (
) and wolves (
) are two apex predators with strong and cascading effects on ecosystem structure and function. After decades of recovery from near extirpation, their ranges now overlap, ...allowing sea otters and wolves to interact for the first time in the scientific record. We intensively studied wolves during 2015 to 2021 in an island system colonized by sea otters in the 2000s and by wolves in 2013. After wolf colonization, we quantified shifts in foraging behavior with DNA metabarcoding of 689 wolf scats and stable isotope analyses, both revealing a dietary switch from Sitka black-tailed deer (
), the terrestrial in situ primary prey, to sea otters. Here we show an unexpected result of the reintroduction and restoration of sea otters, which became an abundant marine subsidy for wolves following population recovery. The availability of sea otters allowed wolves to persist and continue to reproduce, subsequently nearly eliminating deer. Genotypes from 390 wolf scats and telemetry data from 13 wolves confirmed island fidelity constituting one of the highest known wolf population densities and upending standardly accepted wolf density predictions based on ungulate abundance. Whereas marine subsidies in other systems are generally derived from lower trophic levels, here an apex nearshore predator became a key prey species and linked nearshore and terrestrial food webs in a recently deglaciated and rapidly changing ecosystem. These results underscore that species restoration may serve as an unanticipated nutrient pathway for recipient ecosystems even resulting in cross-boundary subsidy cascades.
To determine the extent of gaps in coronavirus disease (COVID-19) vaccine coverage among those in the United States with and without previous COVID-19 diagnoses, we used data from a large, nationally ...representative survey conducted during July 21-August 2, 2021. We analyzed vaccine receipt (≥1 dose and full vaccination) and intention to be vaccinated for 63,266 persons. Vaccination receipt was lower among those who had a prior diagnosis of COVID-19 compared to those without: >1 dose: 73% and 85%, respectively, p<0.001; full vaccination: 69% and 82%, respectively, p<0.001). Reluctance to be vaccinated was higher among those with a previous COVID-19 diagnosis (14%) than among those without (9%). These findings suggest the need to focus educational and confidence-building interventions on adults who receive a COVID-19 diagnosis during clinic visits, or at the time of discharge if hospitalized, and to better educate the public about the value of being vaccinated, regardless of previous COVID-19 infection.

Callous-unemotional traits (CU) traits are characterized by low empathy, guilt, and reduced sensitivity to others' feelings, along with a reduced drive for social affiliation. However, little is ...known about the relationships between CU traits and social affiliation in the school context, or the influence of gender on these associations. This study tested reciprocal associations between CU traits and school-based affiliative relationships and explored gender as a potential moderator.
The sample included South Korean children aged 10 to 12 years (N = 218, M = 11.03, SD = .65, 52% boys). Children reported on CU traits, antisocial behavior, teacher-student relationship quality, and peer affiliation. Three-wave longitudinal cross-lagged models tested reciprocal associations between CU traits and affiliation with both teachers and peers, with multi-group modeling employed to test the moderating effect of gender.
Higher CU traits at time 1 predicted decreases in teacher affiliation at time 2 controlling for CU traits, teacher-child affiliation, and antisocial behavior at time 1, while lower teacher-child affiliation at time 2 predicted increases in CU traits at time 3 accounting for CU traits, teacher-child affiliation, and antisocial behavior at time 2. However, there were no reciprocal associations between CU traits and teacher affiliation nor significant associations between CU traits and peer affiliation. Gender did not moderate any pathways between CU traits and teacher or peer affiliation.
Findings indicate CU traits may reduce teacher-child affiliation, potentially escalating risk for further increases in CU traits. Thus, teacher-child affiliation may represent an important target for school-based intervention for children with elevated CU traits regardless of gender.

Pacific salmon are a keystone resource in Alaska, generating annual revenues of well over ~US$500 million/year. Due to their anadromous life history, adult spawners distribute amongst thousands of ...streams, posing a huge management challenge. Currently, spawners are enumerated at just a few streams because of reliance on human counters and, rarely, sonar. The ability to detect organisms by shed tissue (environmental DNA, eDNA) promises a more efficient counting method. However, although eDNA correlates generally with local fish abundances, we do not know if eDNA can accurately enumerate salmon. Here we show that daily, and near‐daily, flow‐corrected eDNA rate closely tracks daily numbers of returning sockeye and coho spawners and outmigrating sockeye smolts. eDNA thus promises accurate and efficient enumeration, but to deliver the most robust numbers will need higher‐resolution stream‐flow data, at‐least‐daily sampling, and a focus on species with simple life histories, since shedding rate varies amongst jacks, juveniles, and adults.

Social distancing is the core policy response to coronavirus disease 2019 (COVID-19). But, as federal, state and local governments begin opening businesses and relaxing shelter-in-place orders ...worldwide, we lack quantitative evidence on how policies in one region affect mobility and social distancing in other regions and the consequences of uncoordinated regional policies adopted in the presence of such spillovers. To investigate this concern, we combined daily, county-level data on shelter-in-place policies with movement data from over 27 million mobile devices, social network connections among over 220 million Facebook users, daily temperature and precipitation data from 62,000 weather stations, and county-level census data on population demographics to estimate the geographic and social network spillovers created by regional policies across the United States. Our analysis shows that the contact patterns of people in a given region are significantly influenced by the policies and behaviors of people in other, sometimes distant, regions. When just one-third of a state’s social and geographic peer states adopt shelter-in-place policies, it creates a reduction in mobility equal to the state’s own policy decisions. These spillovers are mediated by peer travel and distancing behaviors in those states. A simple analytical model calibrated with our empirical estimates demonstrated that the “loss from anarchy” in uncoordinated state policies is increasing in the number of noncooperating states and the size of social and geographic spillovers. These results suggest a substantial cost of uncoordinated government responses to COVID-19 when people, ideas, and media move across borders.

Abstract Antisocial behavior in childhood and adolescence is associated with poor family and peer relationships, and a higher risk of mental and physical health problems in adulthood, as well as ...criminality. Emotions play a central role in children’s moral development, but most research has focused on negative emotions (e.g., shame and guilt), in relation to childhood antisocial behavior. Research in adult populations indicates that positive emotions experienced in anticipation of, during, and after antisocial acts may play an important role in the development and maintenance of antisocial behavior. Consequently, this systematic review aimed to investigate the relationship between positive emotion and antisocial behavior in children and adolescents. A systematic search in five databases was conducted, yielding 52 studies that used different methodological approaches, samples, designs and methods to examine this association. Results provide support for a positive relationship between positive emotion and antisocial behavior across community, forensic and clinical samples. This link appeared to be stronger for younger children, boys, and for children high in social dominance, callous-unemotional or sensation-seeking traits. Results suggested that positive affect may act in concert with negative emotion, cognitive, personality and motivational processes, as well as peer influences to determine the initiation and maintenance of antisocial behavior. This review presents directions for future research and discusses the implications of findings for prevention and intervention programs for youth with antisocial behavior.

This study examined public comments on Twitter about coronavirus in the weeks after news stories across the globe on the coronavirus outbreak. A total of 600 tweets were assessed (
= 600) for ...sentiment, risks presented, attribution of blame, and outrage. A sample of 300 tweets was taken from Sunday, February 9, through Wednesday, February 19, 2020, and an additional 300 tweets from Sunday, March 1, through Wednesday, March 11, 2020, to assess how public communication changed over time. Results show that risk, blame, and outrage differed significantly between February and March in a variety of ways. Specifically, more significant risks were noted in February than in March, with the majority of March tweets not noting any specific risks. Although most tweets did not present any specific blame, more blame was presented in February than in March, although more tweets in March attributed blame to countries and governments. Finally, outrage varied in several ways, with hazards generally being higher in February and outrage being higher in March.
Background
We previously hypothesised that the early development of psychopathy is associated with a failure to attend to the eyes of attachment figures, and we have presented preliminary data from a ...parent–child ‘love’ scenario in support of this. Here, we confirm the association in a larger sample and test mechanisms of impaired eye contact during expressions of love in control and behaviourally disturbed children.
Methods
Oppositional defiant disorder children, assessed for callous‐unemotional (CU) traits, and controls, were observed in a brief interaction task where the mother was asked to show love to her child. Eye contact and affection were measured for each dyad.
Results
As predicted, there were no group differences in affection and eye contact expressed by mothers; levels of CU traits predicted low levels of eye contact towards their mothers across all groups of children. As expected, low eye contact was correlated with psychopathic fearlessness in their fathers, and maternal reports of negative feelings towards the child. Independent observations showed that child's behaviour largely drives the low eye contact associated with CU traits, and low eye contact was not associated with independent observations of the quality of attachment‐related behaviours in mothers.
Conclusions
Impaired eye contact is a unique characteristic of children with CU traits; these impairments are largely independent of maternal behaviour, but associated with psychopathic traits in the fathers. These impairments should be tested for functional significance and amenability to change in longitudinal and treatment studies.

Objective: This project assessed college students' perceptions of social media conversations about COVID-19 in the United States. Participants: A total of 110 college students completed an online ...survey (N = 110) over two periods of time: April 2020 (n = 60) and September 2020 (n = 50). Method: Measurements included students' perceptions of sentiment, risk, blame, outrage, and opinion/behavioral intention. Results: Survey results showed that college students' attitudes and perceptions of these concepts on social media varied from April to September with negative sentiment, concern, uncertainty, and risk perception decreasing over time while blame and outrage increased over time. A sample of tweets was also examined for these constructs. Conclusions: This study provides important insight on college students' perceptions during a public health emergency and how they use social media as a tool for health information.
