People vary in the extent to which they embrace their society’s traditions, impacting a range of social and political phenomena. People also vary in the degree to which they perceive disparate dangers as salient and necessitating a response. Over evolutionary time, traditions likely regularly offered direct and indirect avenues for addressing hazards; consequently, via multiple possible pathways, orientations toward tradition and toward danger may have become associated. Emerging research documents connections between individual differences in traditionalism and variation in threat responsivity in general, and pathogen-avoidance motivations in particular. Importantly, because threat-mitigating behaviors can conflict with competing priorities, the precise associations between traditionalism and pathogen avoidance likely depend on contextually contingent costs and benefits. The COVID-19 pandemic requires individuals to make decisions about consequential and costly pathogen-avoidance behaviors that can clash with other priorities. The pandemic therefore provides a real-world setting in which to test the posited relationship between traditionalism and pathogen avoidance across socio-political contexts. Across 27 societies (N = 7,844), we find that costly COVID-19-avoidance behaviors positively correlate with greater endorsement of traditional norms and values in a majority of countries. Accounting for the conflict that arises in some societies between public health precautions and competing priorities, such as the exercise of personal liberties, reveals a consistent relationship between traditionalism and COVID-19 precautions across an even wider range of social and cultural contexts. These findings support the thesis that traditionalism is associated with an enhanced tendency to attend to hazards.
Do they know or just do it? Investigating implicit and explicit sequence learning by capuchin monkeys, human adults and children
Authors: Malassis Raphaelle , Seed Amanda
Published: July 2022

In humans, it is now established that sequential regularities can be learned implicitly (i.e. without acquiring conscious knowledge) or explicitly (with acquisition of conscious knowledge). Is this dual-processing capability also the case for non-human primates? In this study, we designed a non-verbal task to probe implicit and explicit sequence learning in capuchin monkeys (Sapajus sp., n = 12), human adults (n = 12), and children from 5 to 10 years old (n = 64). After learning spatial sequences on a touchscreen, participants’ conscious access to the sequences was probed with a forced choice sequence completion test. All performed above chance level in this test, without being instructed or trained to do so. However, only human adults who reported the presence of regularities performed at ceiling level. We suggest future directions that could build on our findings to disentangle implicit and explicit learning in monkeys and children.
The associations between theism and beliefs in folklore, mythical beings, extra-terrestrials, and things that go bump in the dark
Authors: Gan Samuel Ken En , Tay Jian-Hua
Published: July 2022

The belief in the supernatural and paranormal is deeply intertwined in human history and culture with the recent inclusion of science fiction entity types e.g., extra-terrestrials. Investigating for the association between the beliefs in formal religions, pagan, and science fiction with worldview elements, 255 participants were recruited and surveyed. The demographic of the participants and their declared religious affiliation were found to be associated but not with their theistic beliefs using the non-parametric Kruskal-Wallis and Dunn’s tests. Non-monotheistic beliefs, particularly polytheistic and agnostic beliefs were significantly positively associated with beliefs in ghosts (H = 34.51, p < 0.01) and other pagan entities such as nature spirits (H = 36.41, p < 0.01) and luck (H = 28.85, p < 0.01). Monotheists tend to have more significant exclusive beliefs in supernatural entities e.g., angels and demons compared to the other theists including atheists, agnostics, polytheists, and pantheists (H = 53.58, p < 0.01). By gender, females were found to significantly believe in the paranormal (W = 9308, p < 0.01) and ghosts (W = 9308, p < 0.01) more than males. The findings here serve to uncover associations of religious beliefs with supernatural and paranormal beliefs such as extra-terrestrials, luck, and objective morality, with demographic background that includes education and professional vocations. The findings here would inform the basis for future studies on beliefs in supernatural and paranormal entities.
Gender and sexual identity-based inequalities in adolescent wellbeing: findings from the# BeeWell Study
Authors: Marquez Jose , Humphrey Neil , Black Louise , Cutts Megan , Khanna Devi
Published: July 2022

BackgroundGender and sexual minority adolescents experience greater symptoms of psychological distress than their peers, but little is known about broader aspects of their wellbeing. This study examines wellbeing inequalities relating to gender and sexual identity among adolescents from Greater Manchester in the United Kingdom.Method37,978 adolescents (aged 12–15, attending 165 secondary schools) completed surveys of life satisfaction, positive and negative affect (hedonic framework); autonomy, self-esteem, optimism, and positive relationships (eudaimonic framework); and, symptoms of distress and mental wellbeing (complete state framework). Structural correlated factors models were used to assess gender and sexual identity wellbeing inequalities.ResultsThe magnitude of wellbeing inequalities pertaining to gender and sexual identity were routinely substantially greater than those concerning other characteristics (e.g., socio-economic disadvantage). Gender identity wellbeing inequalities followed a consistent pattern, with the largest disparities evident between gender diverse adolescents and boys. Sexual identity wellbeing inequalities also followed a consistent pattern, with the largest disparities evident between sexual minority youth (both gay/lesbian and bi/pansexual) and their heterosexual peers. Finally, variation was evident across wellbeing domains. For example, observed gender identity (boys vs. girls) and sexual identity (heterosexual vs. sexual minority) disparities were substantially greater for symptoms of distress than for mental wellbeing in the complete state model.ConclusionsLGBTQ + adolescents experience lower wellbeing than their peers, and this is evident across a range of wellbeing domains. Accordingly, there is an urgent need for the prioritisation of improved prevention and intervention efforts that can better meet the needs of gender diverse and sexual minority youth, and future research should be conducted to improve understanding of the mechanisms underpinning the wellbeing inequalities observed.
From Panocha to Fudge: Mexican Roots of an American Candy
Authors: Charbonneau Patrick , Pilcher Jeffrey M
Published: July 2022

Although the origins of the popular candy called fudge have been traced to American industrial processed foods of the 1880s, an early version known as panochita de leche was made in eighteenth-century Mexico using only rustic brown sugar and milk. The authors of this article combined the methodologies of physical chemistry and food history to examine the development of this dish using the science of sugar refining as well as manuscript and published cookbook recipes, memoirs, and travel accounts. Given the lack of Old World confectionery antecedents to the key technique of whisking the cooling sugar to induce crystallization, they attribute panochita to vernacular Mexican traditions of sugar refining and candy making.
Simple Requests Help Desk-Based Workers Stand Up More: A Meta-Analytic Summary
Authors: Bartmann Nina , Corbin Jonathan Charles
Published: July 2022

In a series of eight studies, spanning laboratory and field experiments, we examined the effect of messages describing the present and/or future consequences of prolonged sitting on standing behavior among desk-based workers. Providing a meta-analytic summary of our findings, we show that the exact phrasing of the message to encourage standing doesn’t produce differing results, but simply asking participants to invest in their health results in a standing rate of roughly 71% across studies and a range of demographics. In addition, our studies highlight the significance of friction; not only does the proportion of participants who chose to stand up decrease as the behavior of standing up becomes more burdensome, but also as the required time commitment increases. Lastly, we present insights on the impressions given by the message content, highlighting that while the effect of the messaging on standing may be indistinguishable, how the messages are perceived matters and should be taken into account.
European Monetary Unification through Novation. The Political Economy of the TARGET System
Authors: Murau Steffen , Giordano Matteo
Published: July 2022

When Economic and Monetary Union became effective in January 1999, it remained unclear what accounting treatment to choose for claims and obligations that the Eurosystem’s National Central Banks (NCBs) incur against each other in the ‘Trans-European Automated Real-Time Gross Express Transfer’ (TARGET) system. The Governing Council of the European Central Bank (ECB) decided only later in 1999 that they should be shifted to the ECB as an intermediating balance sheet—a process called ‘novation’. This decision has decisively shaped the countenance of the monetary union and its fate throughout the subsequent two decades but so far escaped the scrutiny of scholarship in International Political Economy (IPE). This paper adopts the perspective of critical macro-finance, which approaches the monetary system as a hierarchical web of interlocking balance sheets, to study the political-economic role of the TARGET system and its successor, the TARGET2 system. We theorize on monetary unification and show that novation of claims and obligations to a third-party balance sheet is not the only possible solution to ‘stitch together’ separate monetary systems at their apex, but likely was the only one politically feasible. Drawing on historical TARGET and TARGET2 data, we explain how the novation method at the top of the hierarchy has repeatedly served to defend the integrity of the monetary union, both monetarily and politically. It has also enabled the evolution of the ECB balance sheet as an idiosyncratic tool that the Eurosystem could use to tackle multiple problems, in particular setting up swap lines and introducing unconventional monetary policy.
Modeling and forecasting healthy life expectancy with Compositional Data Analysis
Authors: Bergeron-Boucher Marie-Pier , Strozza Cosmo , Simonacci Violetta , Oeppen Jim
Published: July 2022

Will the extra years of life gained by the increase in life expectancy be lived in good or poor health? As forecasts support social, economic and medical decisions, as well as individuals' choices, there is a clear rationale for forecasting healthy life expectancy (HLE). However, only a limited number of models is available to forecast HLE. We here suggest two models to forecast health and mortality simultaneously and coherently. One model is based on the Sullivan method to estimate HLE and the second one on the multistate life table method. Both models use Compositional Data Analysis (CoDA) to account for the coherence between health and mortality. Mortality and health at age 50 and above is forecast for Spanish and Swedish females. Both models provide similar estimates and forecasts of HLE, estimating and predicting a compression of morbidity in Sweden and a dynamic equilibrium in Spain.
The nature and context of online communication in promoting prosocial behaviour in youth: A systematic review
Authors: Buckley Lisa , Fowler James , Bankole Elijah
Published: July 2022

Adolescent social media use is ubiquitous and a major means of communication with friends, including how they might look after friends, protect them, and be helpful bystanders. This review seeks to summarise the literature on how features of social media platforms, such as public/ private posts, use of images/ text, are related to likelihood of adolescent prosocial behaviour. We included a broad definition of prosocial, reflecting provision of comfort, volunteering, public donation, information support, and active defending (to minimise harm). We identified 14 studies and whilst we allowed for any form of prosocial behaviour, most focused on defending in cyberbullying contexts. Regarding social media features, studies highlighted being able to be observed, and to observe others, whether friends or strangers (often study confederates) altered the likelihood of prosocial behaviour, suggesting public vs private posting options are important. In addition, features of ‘likes’ and posting an image (vs text) altered prosocial behaviour. More prosocial behaviour was evident when there were ‘likes’ from peers (study confederates, vs being alone) and where the post had an image (vs text). Overall, findings highlight features of social media have a role to play in whether adolescents are more likely to be prosocial. Findings have important implications for designing social media interventions to promote adolescent prosocial behaviour.

Fantasies of Violence in the Patriot/Militia Movement in the United States
Authors: Jackson Sam
Published: July 2022

This chapter explores the history of one prominent form of anti-government right-wing extremism in the United States called the patriot/militia movement. After situating the movement within the broader context of right-wing extremism in the United States, it provides a few examples of actors and organizations in the movement. Next, it describes three waves of this movement, beginning with the first wave in the 1990s; it suggests that after the January 6 insurrection in Washington, D.C., the movement is in a transitional period that could see a return to its structure, activity, and ideas during wave 2 (2008–2016) or a continuation of its trajectory during wave 3 (during the years of the Trump administration). Throughout this discussion of the movement’s history, it highlights the fantasies of violence that have animated those involved in this form of extremism, noting as well that these fantasies sometimes erupt into actual violence (or plots of violence).
Authoritarianism, Political Attitudes, and Vote Choice: A Longitudinal Analysis of the British Electorate
Authors: Vasilopoulos Pavlos
Published: July 2022

The nature, measurement, and correlates of the psychological trait of authoritarianism have spurred an intense and long-lasting debate in political psychology, dating back to the 1950s. This article aims at advancing extant knowledge on authoritarianism -measured here by child-rearing items- in two ways. First, by investigating the impact of authoritarianism on political attitudes and voting, net of individual heterogeneity, thus improving causal estimation. Second, by investigating the extent to which there exists reverse causality between authoritarianism and political attitudes. To do so, I employ a longitudinal analysis that covers a timespan of two years using the 2021 British Election Study Panel. Results suggest that authoritarianism has an impact on intolerance to immigration, the endorsement of populist attitudes, and opposition to economic redistribution. Yet, the analysis shows that these relationships are bidirectional as authoritarianism scores both influence and are influenced by political attitudes. Further, the findings point to a lack of causal association between authoritarianism and vote choice in the British electorate. These results indicate that authoritarianism measured with child-rearing items impacts upon political attitudes, net of individual heterogeneity.
Approaching transnational Chinese queer stardom as zhongxing (‘neutral sex/gender’) sensibility
Authors: Li Eva Cheuk-Yin
Published: July 2022

EAJPC preprints 2015-A generation of female queer stars has emerged in post-millennial transnational Chinese popular culture. They have amassed many female followers. Among these stars are Mainland China’s Chris Lee, Hong Kong’s Denise Ho and Taiwan’s Jing Chang. These celebrities are often characterized as ‘zhongxing’, which literally means ‘neutral sex and/or gender’, because of their non-normative gender and ambiguous sexual representation. This article aims to develop a lens to approach this emergence of queer stars and its sociocultural implications. Considering the genealogy of zhongxing and its historical relevance and taking on the reflections of Anglo-American queer theory, this article justifies the use of zhongxing over the usual English term ‘androgyny’. Recent media scholarship on Chinese queer stardom has provided an insightful entry point to this phenomenon. In this article, zhongxing is conceptualized as a sensibility for its liminal status as a non-identity category and non-sexual practice. It is ambiguous but also gradually being stabilized and shaped as specific forms of embodiment, a quest for individuality and reflexive authenticity, and an emerging queer feeling. The potentiality of zhongxing sensibility, as suggested by preliminary interview data, invites further research in the affective texture of everyday life and the transforming contours of gender and sexuality in transnational Chinese societies.

In essence, humans need social life because they cannot be separated from other humans, therefore social skills are needed from an early age. One of the efforts in developing these skills is being active in various organizations, this is intended for students to create social skills, not even that, but students must be dynamic, not monotonous. Nowadays, there are a lot of social problems that are often carried out by various groups, especially students in the classroom and outside the classroom, such as some students' attitudes that are individualistic, selfish, have closed personalities and do not even pay attention to the teacher when giving explanations. Therefore, the author aims to explore the problems of various discussions about what efforts can be felt by many people so as to create a person who is fun or likes to be social. By using a quantitative writing method in which the author uses a literature study by reading references from several journal articles, books, so that there are problems being researched and then finding targets, data collection techniques and solutions to problems.
Bottomonium suppression and elliptic flow in heavy-ion collisions
Authors: Strickland Michael
Published: July 2022

In this proceedings contribution I review recent progress concerning the suppression of bottomonium production in the quark-gluon plasma.  Making use of open quantum system methods applied to potential non-relativistic quantum chromodynamics one can show that the dynamics of heavy-quarkonium bound states satisfying the scale hierarchy 1/a0 » πT ∼ mD  » E obey a Lindblad equation whose solution provides the quantum evolution of the heavy-quarkonium reduced density matrix.  To solve the resulting Lindblad equation we use a quantum trajectories algorithm which allows one to include all possible angular momentum states of the quark-antiquark probe in a scalable manner.  We solve the Lindblad equation using a tuned 3+1D dissipative hydrodynamics code for the background temperature evolution.  We then consider a large number of Monte-Carlo sampled bottomonium trajectories embedded in this background.  This allows us to extract the centrality- and pT-dependence of the nuclear suppression factor RAA[Υ] and elliptic flow v2[Υ].  We find good agreement between our model predictions and available √ sNN = 5.02 TeV = 5.02 TeV Pb-Pb collision experimental data from the ALICE, ATLAS, and CMS collaborations.
RESEARCH OF DESIGNS OF THE AXIAL DRUM EQUIPMENT OF STONE MATERIAL SORTING
Authors: Gunsen Ganbaatar  , Yadam Renchinvanjil
Published: July 2022

There are studies showing that 10% of the total energy generated in the world is spent on crushing and sifting and sorting processes in mining sectors. 52.7% of the total mining industries extract metal ores, and 36.3% of them extract coal. It can be seen that there is a need for sorting the materials with particles in these sectors. According to the needs, the energy expenditure is high and the devices and equipment used still maintain their traditional designs and makes. The process of sorting out the materials with particles is sifted by the flat-surfaced, trommel-shaped, and cylindrical mesh surfaces positioned on the vertical axis. The above methods are still in use, and this becomes the basis of mechanical sifting methods. Therefore, the researchers continue to work on perfecting the above methods. The goal of this research work is to survey and determine the possibility that changes in the designs of sifting equipment with the trommels can improve the influences that are created during the sifting process, the efficiency of sifting, and the productivity of the device or equipment. In this research work, with the purpose to improve the parameters of sifting materials with particles, we will change the design of the cylindrical trommel of the cross trommel sieve, which is often used in the sifting process to the axle to its axis, and in order to confirm the results of the experiment by determining the CAD analysis of axle trommel and the movement of one particle inside of it using the ADAMS software, the experiment on the real equipment shall be rationalized by putting into the mathematic modeling, develop the physical modeling using the “EDEM solution” software and process the results.

Endovascular intervention for bilateral paramedian thalamic stroke due to occlusion of the unilateral P1 segment of the posterior cerebral artery: illustrative cases
Authors: Yoshida Jun , Akamatsu Yosuke , Kojima Daigo , Miyoshi Kenya , Kashimura Hiroshi , Ogasawara Kuniaki
Published: July 2022

BACKGROUND

Occlusion of the unilateral P1 segment can result in bilateral paramedian thalamic infarction in patients with anatomical variants of the bilateral paramedian thalamic artery arising from a single P1 segment. Despite the life-threatening presentation of bilateral paramedian thalamic stroke, timely diagnosis is often challenging.

OBSERVATIONS

The authors herein describe 3 patients treated with endovascular intervention for occlusion of the unilateral P1 segment wherein the bilateral paramedian thalamic arteries arose. All patients were admitted to the authors’ emergency department with sudden-onset coma and respiratory distress; however, initial computed tomography was unremarkable. Despite suspicion of basilar artery occlusion, vertebral and carotid angiography revealed occlusion of the unilateral P1 segment. All patients were successfully treated with endovascular intervention. Overall, 2 patients had favorable outcomes (modified Rankin scale [mRS] scores of 0 and 1), whereas in 1 patient, the mRS score reached a baseline score of 3.

LESSONS

In patients with the variant of the bilateral paramedian thalamic artery arising from a single P1 segment, occlusion of the unilateral P1 segment can be life threatening; nevertheless, timely endovascular treatment is effective. Carotid and vertebral angiography, rather than magnetic resonance or computed tomography angiography, is useful for immediate and reliable diagnosis of the relatively small vascular lesions.
