Do moral values change with the seasons?

Moral values guide consequential attitudes and actions. Here, we report evidence of seasonal variation in Americans' endorsement of some-but not all-moral values. Studies 1 and 2 examined a decade of data from the United States (total N = 232,975) and produced consistent evidence of a biannual seasonal cycle in values pertaining to loyalty, authority, and purity ("binding" moral values)-with strongest endorsement in spring and autumn and weakest endorsement in summer and winter-but not in values pertaining to care and fairness ("individualizing" moral values).

Bird communities across different levels of human settlement: A comparative analysis from two northern Amazonian ecoregions.

Urban ecosystems are increasingly dominating landscapes globally, so it is critical to understand the effects of human settlements on biodiversity. Bird communities are effective indicators because they are impacted by the size and expansion of human settlements, exemplified by changes in their habitat use, breeding and foraging behaviours, as well as patterns of richness and abundance. Existing studies on bird community responses to human settlements have mainly focused on single ecoregions and large cities, leaving a gap in comparative research on how differently sized human settlements affect bird communities across various ecoregions.

Less biased yet more defensive: The impact of control processes.

Educational and training programs designed to reduce racial bias often focus on increasing people's awareness of psychological sources of their biases. However, when people learn about their biases, they often respond defensively, which can undermine the effectiveness of antibias interventions and the success of prejudice regulation. Using process (Quad) modeling, we provide one of the first investigations of the relationships between (a) controlled and automatic cognitive processes that underpin performance on the Implicit Association Test and (b) defensive reactions to unflattering implicit racial bias feedback.

Implicit and explicit COVID-19 associations and mental health in the United States: a large-scale examination and replication.

Background: Given the sensitive nature of COVID-19 beliefs, evaluating them explicitly and implicitly may provide a fuller picture of how these beliefs vary based on identities and how they relate to mental health.

Objective: Three novel brief implicit association tests (BIATs) were created and evaluated: two that measured COVID-19-as-dangerous (vs. safe) and one that measured COVID-19 precautions-as-necessary (vs.

The role of uncertainty, worry, and control in well-being: Evidence from the COVID-19 outbreak and pandemic in U.S. and China.

Uncertainty about the future often leads to worries about what the future will bring, which can have negative consequences for health and well-being. However, if worry can act as a motivator to promote efforts to prevent undesirable future outcomes, those negative consequences of worry may be mitigated. In this article, we apply a novel model of uncertainty, worry, and perceived control to predict psychological and physical well-being among four samples collected in China (Study 1; during the early COVID-19 outbreak in China) and the United States (Studies 2-4, during 4 weeks in May 2020, 4 weeks in November 2020, and cross-sectionally between April and November 2020).

Who is more likely to ignore experts' advice related to COVID-19?

Failing to adhere to COVID-19 experts' advice could have devastating consequences for individuals and communities. Here we determine which demographic factors can impact trust in COVID-19 experts. Participants consisted of more than 1875 online volunteers, primarily from the U.

Exposure and Aversion to Human Transmissible Diseases Predict Conservative Ideological and Partisan Preferences.

The objective prevalence of and subjective vulnerability to infectious diseases are associated with greater ingroup preference, conformity, and traditionalism. However, evidence directly testing the link between infectious diseases and political ideology and partisanship is lacking. Across four studies, including a large sample representative of the U.

Magnetized decaying turbulence in the weakly compressible Taylor-Green vortex.

Magnetohydrodynamic (MHD) turbulence affects both terrestrial and astrophysical plasmas. The properties of magnetized turbulence must be better understood to more accurately characterize these systems. This work presents ideal MHD simulations of the compressible Taylor-Green vortex under a range of initial subsonic Mach numbers and magnetic field strengths.

Formation of massive black holes in rapidly growing pre-galactic gas clouds.

The origin of the supermassive black holes that inhabit the centres of massive galaxies remains unclear. Direct-collapse black holes-remnants of supermassive stars, with masses around 10,000 times that of the Sun-are ideal seed candidates. However, their very existence and their formation environment in the early Universe are still under debate, and their supposed rarity makes modelling their formation difficult.

Measuring implicit attitudes: A positive framing bias flaw in the Implicit Relational Assessment Procedure (IRAP).

How can implicit attitudes best be measured? The Implicit Relational Assessment Procedure (IRAP), unlike the Implicit Association Test (IAT), claims to measure absolute, not just relative, implicit attitudes. In the IRAP, participants make congruent (Fat Person-Active: false; Fat Person-Unhealthy: true) or incongruent (Fat Person-Active: true; Fat Person-Unhealthy: false) responses in different blocks of trials. IRAP experiments have reported positive or neutral implicit attitudes (e.

From F = ma to flying squirrels: curricular change in an introductory physics course.

We present outcomes from curricular changes made to an introductory calculus-based physics course whose audience is primarily life sciences majors, the majority of whom plan to pursue postbaccalaureate studies in medical and scientific fields. During the 2011-2012 academic year, we implemented a Physics of the Life Sciences curriculum centered on a draft textbook that takes a novel approach to teaching physics to life sciences majors. In addition, substantial revisions were made to the homework and hands-on components of the course to emphasize the relationship between physics and the life sciences and to help the students learn to apply physical intuition to life sciences-oriented problems.

The formation of Population III binaries from cosmological initial conditions.

Previous high-resolution cosmological simulations predicted that the first stars to appear in the early universe were very massive and formed in isolation. Here, we discuss a cosmological simulation in which the central 50 M(o) (where M(o) is the mass of the Sun) clump breaks up into two cores having a mass ratio of two to one, with one fragment collapsing to densities of 10(-8) grams per cubic centimeter. The second fragment, at a distance of approximately 800 astronomical units, is also optically thick to its own cooling radiation from molecular hydrogen lines but is still able to cool via collision-induced emission.

Factitious Disorders: the Baron's legacy.

Our understanding of factitious disorders has expanded from that of medical and surgical exotica into that of a much broader psychiatric disorder. Patients can be divided into a nuclear group (classical Munchausen), a larger non-nuclear and less socially deviant group, and children involved by proxy. There are many aetiological theories, ranging from the psychoanalytic to the organic, and at least some cases are learned at home.
