Motivated political reasoning is a central phenomenon in political psychology, but no scholarly consensus exists as to its cause. In one influential account, motivated political reasoning is caused by goals to control emotional states. This explanation is often assumed, but has rarely been tested empirically. It implies, I argue, that individual differences in how people control their emotions (i.e., in emotion regulation strategies) should influence outcomes caused by motivated political reasoning, such as perceptual divides over politically relevant facts. I hypothesize such perceptual divides to be negatively associated with emotional acceptance and positively associated with cognitive reappraisal—two key emotion regulation strategies. I test these hypotheses in the specific context of reasoning about facts related to immigration politics in Denmark using a mix of experimental and cross-sectional survey data from three nationally representative samples of the Danish voter population (total N = 4186). In the specific context of the present study, the results do not support the often-assumed idea that motivated political reasoning is driven by efforts to regulate emotions. These findings raise important questions about the conditions under which emotion regulation might play a role in motivated political reasoning.
Flapping-based propulsive systems rely on fluid–structure interactions to produce thrust. At intermediate and high Reynolds numbers, vortex formation and organisation in the wake of such systems are crucial for the generation of a propulsive force. In this work, we experimentally investigate the wake produced by a tethered robotic fish immersed in a water tunnel. By systematically varying the amplitude and frequency of the fish tail as well as the free stream speed, we are able to observe and characterise different vortex streets as a function of the Strouhal number. The produced wakes are three-dimensional and exhibit a classical V-shape, mainly with two oblique trains of vortex rings convecting outward. Using two-dimensional particle image velocimetry in the mid-span plane behind the fish and through extensive data processing of the velocity and vorticity fields, we demonstrate the strong couplings at place between vortex dynamics, thrust production and wake structure. The main results are twofold. First, by accounting for the obliqueness of the vortex trains, we quantify in experiments the evolution of vortex velocity components in both streamwise and transverse directions. We also measure key geometrical and dynamical properties such as wake angle, vortex ring orientation, diameter and vorticity. Remarkably, all of these quantities collapse onto master curves that also encompass data from previous studies. Second, we develop a quasi-two-dimensional model that incorporates both components of the momentum balance equation and introduces an effective spanwise thickness of the wake structure. This additional dimension, which scales with the physical thickness of the fish, captures the fine features of the three-dimensional wake. The model successfully explains the experimental master curves and highlights the links between vortex dynamics, thrust and wake geometry. Together, this framework offers a comprehensive understanding of the influence of the Strouhal number, providing universal insights relevant for both biological locomotion and bio-inspired propulsion systems.
Through ethnographical, historical, archival, and analytical lenses, this article explores Zheng Xiaoying’s (1929–) Mandarin re-translations of Das Lied von der Erde as a prism that refracts critical light on intersections of translation, epistemology, interculturality, and post-/decoloniality. The article first provides a reception history of Das Lied in China to contextualize Zheng’s re-translations, and then examines her archives to discuss the cultural dynamics of translation and musical knowledge-making in China. The article ends with a provocation from Hong Kong to reflect on the stakes of celebrating translation as a theoretical apparatus for transnational music-historical flows and decolonial goals, and to position translation in intercultural musical exchange as an arbiter of knowledges, cultures, nationhood, and politics.
The parasitoid wasp Habrobracon hebetor Say (Hymenoptera: Braconidae) is one of the important parasitoids used for the biological control of larval stages of moths such as Pyralidae and Noctuidae, which include major agricultural, orchard, and stored product pests. This wasp species is widely utilised in biological control programmes targeting these economically significant lepidopteran pests. In this study, the sublethal effects of four insecticides (tetranelypyrole, flupyradifurone, flubendiamide, and spirotetramat) on the biological parameters of the parasitoid wasp H. hebetor were investigated using demographic toxicology methods. The parasitoid wasp was reared on larvae VI of the Mediterranean flour moth in a growth chamber (27 ± 2°C, 65 ± 5% RH, and a photoperiod of 16:8 (light:dark) hours). The estimated LC25 values from the bioassay experiments on the adult stage of the wasp were used. The estimated LC25 values were 30.8, 130.8, 807, and 34.2 µg ai/L for tetraniliprole, flupyradifurone, flubendiamide, and spirotetramat pesticides, respectively. The results showed that the net reproductive rates (R0) due to treatment by tetraniliprole, flupyradifurone, flubendiamide, spirotetramat, and control were 50.25, 50.66, 64.72, 57.49, and 71.33 females per generation, respectively. The intrinsic rate of population increase (rm) was 0.226, 0.240, 0.242, 0.238, and 0.259 females/female/generation for tetraniliprole, flupyradifurone, flubendiamide, spirotetramat, and control, respectively. The population parameters calculated included the age-stage age-specific survival rate (lx) and age-specific fecundity of the total population (mx). The demographic toxicology analysis showed that tetraniliprole had the highest toxicity, while flubendiamide had the lowest toxicity to adult wasps. In case of conducting additional field tests and confirming the laboratory results, it can be concluded that the insecticides flupyradifurone and flubendaimide may be suitable options for integrated pest management programs.
The financialisation of eldercare has become an internationally widespread phenomenon with significant implications. Previous literature has shown how finance-controlled providers (FCPs) initially launch their eldercare services throughout urban areas, but we know little about the ways that these providers subsequently expand their services. Focusing on nursing homes in Swedish eldercare, our aim with this paper is to develop new knowledge about the expansion strategies guiding FCPs. Deploying a Bourdieusian field perspective to analyse rich document data from Sweden’s three largest FCPs, we found that they sensed ‘booming opportunities’ following demographic trends among older citizens and economic difficulties within municipalities. However, we also find that FCPs perceived ‘looming challenges’ deriving from labour shortages and profit debates in the public sector, indicating demographic trends and economic difficulties were tough to leverage as opportunities. FCPs attempted to overcome such challenges through expansion strategies centred on acquiring eldercare providers and – most notably – building nursing homes. Our findings advance the literature on eldercare financialisation by highlighting how FCPs, in devising expansion strategies, not only adopt financial tools but also incorporate field perceptions. These strategies are ultimately utilised by FCPs to expand their positions as policy actors throughout welfare states that have undergone market-inspired reforms.
The “Critically Endangered” Cherry-throated Tanager Nemosia rourei is endemic to the Atlantic Forest of south-eastern Brazil, and extremely rare for reasons that are not yet fully understood. We monitored reproductive activities of the only known individuals of the species, at two sites, between October 2018 and November 2023. The birds foraged in social groups of 5–8 individuals. Ten nests, built in trees at heights of 12–26 m, were monitored through continuous direct observation. Most reproductive activity occurred between October and end of November, with one further nest found in March. Clutch size was 3–4 eggs, the incubation and nestling periods were 16 days, and the chicks were fed mainly on invertebrates. Up to six nest helpers, likely young from previous seasons, assisted with the collection of nest material, feeding the chicks, and defending the nest. Reproductive success was 50%, with losses due to climatic conditions (rain and cold) and predation, but may have been enhanced by the efforts of the researchers in scaring away potential predators including Spot-billed Toucanet Selenidera maculirostris and Black Capuchin Sapajus nigritus. These findings reinforce the value of detailed observation of social groups and their nests, and continuing efforts to deter predators. Further research could address how parental care and nest helpers affect reproductive success. The availability of large trees with abundant lichens may be a limiting factor for the reproductive success of species in the long term, and so protecting and restoring habitat with such features is crucial for the long-term conservation of this species.
Mass-casualty incidents (MCI) are a highly important issue in disaster medicine today. In this context, professional first responders play a fundamental role as they provide preparedness and initial care to the injured. The aim of this review is to describe the form and impact of different didactic concepts in triage exercises to prepare for an MCI response.
Methods
A Scoping review search was conducted in the databases PubMed, Medline, and Psyndex as an initial examination of this topic.
Results
Seventeen studies were included in this review. Of the reviewed studies, 52.9% followed a randomized controlled trial design with pre-post intervention measurement. The interventions implemented in the studies were associated with an increase in knowledge and/or practical skills. Of media-based interventions, 42.9% show a comparable and 57.1% greater training effect than conventional teaching methods. According to 4 studies, technical and non-technical aids increase the triage accuracy.
Conclusions
The benefits of media-based interventions and of technical and non-technical aids should be evaluated by a subsequent systematic review with a broader database and search terms of studies. The differences between different triage algorithms need to be investigated in future studies. It must be noted that intervention is preferable to non-intervention.
Targeting the glutamatergic system is posited as a potentially novel therapeutic strategy for psychotic disorders. While studies in subjects indicate that antipsychotic medication reduces brain glutamatergic measures, they were unable to disambiguate clinical changes from drug effects.
Aims
To address this, we investigated the effects of a dopamine D2 receptor partial agonist (aripiprazole) and a dopamine D2 receptor antagonist (amisulpride) on glutamatergic metabolites in the anterior cingulate cortex (ACC), striatum and thalamus in healthy controls.
Method
A double-blind, within-subject, cross-over, placebo-controlled study design with two arms (n = 25 per arm) was conducted. Healthy volunteers received either aripiprazole (up to 10 mg/day) for 7 days or amisulpride (up to 400 mg/day) and a corresponding period of placebo treatment in a pseudo-randomised order. Magnetic resonance spectroscopy (1H-MRS) was used to measure glutamatergic metabolite levels and was carried out at three different time points: baseline, after 1 week of drug and after 1 week of placebo. Values were analysed as a combined measure across the ACC, striatum and thalamus.
Results
Aripiprazole significantly increased glutamate + glutamine (Glx) levels compared with placebo (β = 0.55, 95% CI [0.15, 0.95], P = 0.007). At baseline, the mean Glx level was 8.14 institutional units (s.d. = 2.15); following aripiprazole treatment, the mean Glx level was 8.16 institutional units (s.d. = 2.40) compared with 7.61 institutional units (s.d. = 2.36) for placebo. This effect remained significant after adjusting for plasma parent and active metabolite drug levels. There was an observed increase with amisulpride that did not reach statistical significance.
Conclusions
One week of aripiprazole administration in healthy participants altered brain Glx levels as compared with placebo administration. These findings provide novel insights into the relationship between antipsychotic treatment and brain metabolites in a healthy participant cohort.
Performers have enacted Beethoven in ways that disclose overt similarities in the ways through which they conceptualize both the composer’s music, and their own ambitions in performing it. This article looks at the pianist Anton Rubinstein (1829–1894) who became known as ‘Van II’ not for his compositions but rather his performances. The focus the late nineteenth-century demand for autobiographic readings, and their blurring of boundaries between fact and fiction, sets the scene for Rubinstein’s role in the creation of a Russian obsession with the performance of Beethoven’s piano works. Rubinstein’s fame for being a ‘son born of Beethoven’ continued well beyond his death, and set a precedent for other pianists to look to his Beethoven legacy to fashion themselves as what Stefaniak has termed ‘revelatory interpreters’ of the composer. The resulting Beethoven–Rubinstein synthesis resulted in a counterpart obsession that peaked in the late-Soviet landscape of the mid-twentieth century. The article turns to the case of Heinrich Neuhaus (1888–1964) to give a sense of how this active myth-making reflected itself in the construction of a performance narrative by a pianist who had never seen or heard Rubinstein but who felt compelled to enact the language, metaphors, and physical trope of the Beethoven-Rubinstein synthesis. It suggests how, in Neuhaus’s case, enacting the Beethoven–Rubinstein synthesis perhaps underpinned aspects of his own pianism (such as the concept of intonirovaniye (a way of intoning sound) as a manifestation of revelatory interpretation) in Beethoven’s Piano Sonata in A-flat major Opus 110.
Recent decades have seen a renewal of interest in panpsychism as a solution to the hard problem of consciousness. This has, in part, also driven an increase in interest in classical Indian philosophical traditions among analytic philosophers of mind. Many of these cross-cultural studies pertaining to panpsychism (and cosmopsychism) have focused on one particularly influential school of Indian philosophy, Advaita (non-dual) Vedānta, the most famous proponent of which is Śaṅkara. In this work, we would like to consider the view of another influential philosopher and the school that developed based on his view – Rāmānuja (eleventh century CE) and Viśiṣṭādvaita (qualified non-dualism) Vedānta. We argue that a cosmopsychist-panentheistic metaphysics that is motivated by Rāmānuja’s views offers a solution to the hard problem that is preferable to other comparable views and could form the basis for a panentheistic conception of God that is compatible with the reality of the freedom of human selves.
Counterterrorism is both a reaction to and an anticipation of the activities of those who wield terror for political purposes. Counterterrorism pits itself against terrorism, aimed at ending or at least limiting its operations, spread, and damage. As Richard English has acknowledged, non-state terrorism has much less impact on the world than the counterterrorism it elicits. The vast powers at the disposal of states and their reactive tendency to military methods, such as after 9/11, make this entirely predictable. Fiona de Londras’ examination of transnational counterterrorism ably documents how states acting in concert have reshaped the world, particularly in the post 9/11 era. Guendalina Simoncini’s book on Tunisia clearly illustrates how counterterrorism can be used to enable the establishment of an authoritarian regime in Tunisia and the resultant disastrous consequences for that society.
