How was former U.S. President Donald Trump’s rhetoric crafted to appeal to a public that cross-cut class, racial, and ethnic boundaries? Significant scholarship has addressed the prevalence of racism and xenophobia in Trump’s language; nevertheless Trump was able to build a broad political coalition despite this derogatory speech. This article examines the ways in which Trump leverages producerist discourse by using race as a modality to construct a moral argument about the worthiness of the figure of the ‘maker’—the entrepreneurial protagonist of his rhetoric. Using a discourse analytic framework, it highlights how Trump uses stance to indirectly racialize and gender the subjects of his talk. The aim of this article is twofold. First, furthering scholarship on racialization and colorblind racism, it offers a discourse-based method for analyzing how an explicitly racist and exclusionary discourse can be interpreted by audiences as an inclusive one. Second, building on scholarship on Trump’s rhetoric, it shows how racialized, gendered, and anti-Semitic language is part of a discursive formation that makes the neoliberal ideal of producerism appealing to an expanding political coalition—paradoxically because it is a moralizing discourse that names outsiders. By analyzing stance-taking within discourses of ressentiment, it is possible to understand how racialized and gendered ideologies and anti-Semitism work together to simultaneously include and exclude non-White audiences.
This article seeks to investigate the claim that South Georgia may have been first discovered in April 1675 by an English merchant called Antonio de la Roche. There are two unresolved questions: whether La Roche was the first to see the island, and whether the island that he saw was South Georgia. I introduce a third uncertainly by questioning whether Antonio de la Roche ever existed. He does not appear in the records of the French churches in London, and the sole source of his biography is the work of a fabricator, Francisco de Seyxas.
The companion 1763 tort cases of Huckle v Money and Wilkes v Wood hold a mythical status in the Anglo-American common law imagination. Few modern accounts of the doctrinal origins of exemplary (or punitive) damages omit reference to them. This article contends that the assumption that these two cases combined to provide damages above and beyond compensation a positive basis at English common law is misconceived. Set back into their historical context, it shows that their true significance is at odds with the decidedly lawmaking significance often ascribed to them by modern judges and scholars alike.
In this article, we prove several refined versions of the classical Bohr inequality for the class of analytic self-mappings on the unit disk $ \mathbb {D} $, class of analytic functions $ f $ defined on $ \mathbb {D} $ such that $\mathrm {Re}\left (f(z)\right )<1 $, and class of subordination to a function g in $ \mathbb {D} $. Consequently, the main results of this article are established as certainly improved versions of several existing results. All the results are proved to be sharp.
Childhood adversity has been associated with hypothalamic–pituitary–adrenal axis dysregulation, which is associated with mental and physical health consequences. However, associations between childhood adversity and cortisol regulation in the current literature vary in magnitude and direction. This multilevel meta-analysis examines the association between childhood adversity and diurnal cortisol measures, as well as potential moderators of these effects (adversity timing and type, study or sample characteristics). A search was conducted in online databases PsycINFO and PubMed for papers written in English. After screening for exclusion criteria (papers examining animals, pregnant women, people receiving hormonal treatment, people with endocrine disorders, cortisol before age 2 months, or cortisol after an intervention), 303 papers were identified for inclusion. In total, 441 effect sizes were extracted from 156 manuscripts representing 104 studies. A significant overall effect was found between childhood adversity and bedtime cortisol, r = 0.047, 95% CI [0.005, 0.089], t = 2.231, p = 0.028. All other overall and moderation effects were not significant. The lack of overall effects may reflect the importance of the timing and nature of childhood adversity to adversity’s impact on cortisol regulation. Thus, we offer concrete recommendations for testing theoretical models linking early adversity and stress physiology.
The helix approach is a new individual pitch control method to mitigate wake effects of wind turbines. Its name is derived from the helical shape of the wake caused by a rotating radial force exerted by the turbine. While its potential to increase power production has been shown in previous studies, the physics of the helical wake are not well understood to date. Open questions include whether the increased momentum in the wake stems from an enhanced wake mixing or from the wake deflection. Furthermore, its application to a row of more than two turbines has not been examined before. We study this approach in depth from both an analytical and numerical perspective. We examine large-eddy simulations (LES) of the wake of a single turbine and find that the helix approach exhibits both higher entrainment and notable deflection. As for the application to a row of turbines, we show that the phase difference between two helical wakes is independent of ambient turbulence. Examination of LES of a row of three turbines shows that power gains greatly depend on the phase difference between the helices. We find a maximum increase in the total power of approximately 10 % at a phase difference of $270^\circ$. However, we do not optimise the phase difference any further. In summary, we provide a set of analytical tools for the examination of helical wakes, show why the helix approach is able to increase power production, and provide a method to extend it to a wind farm.
We develop the theory of Kim-independence in the context of NSOP$_{1}$ theories satisfying the existence axiom. We show that, in such theories, Kim-independence is transitive and that -Morley sequences witness Kim-dividing. As applications, we show that, under the assumption of existence, in a low NSOP$_{1}$ theory, Shelah strong types and Lascar strong types coincide and, additionally, we introduce a notion of rank for NSOP$_{1}$ theories.
Temporality is important for understanding Hong Kong's postcolonial status since its handover from Britain to China in 1997. This study examines the mediated regimes of postcolonial temporalities in coverage of five anniversaries of the Hong Kong handover (between 1998 and 2020) in Chinese and British newspapers. In 1998, the Chinese and British press shared a significant consensus regarding the “legitimate continuity” of Hong Kong's colonial legacies; however, this consensus was increasingly undermined by ideological contestations surrounding the city's postcolonial ruptures and differences. The multiple temporal claims that emerged in Chinese and British newspapers were systemized within a proposed framework that combined temporal modes (the “formal structures” of temporal relations) and ideological appraisals (the “general politics” where temporal modes are (il)legitimized and (ab)normalized). The temporal complexity concerning Hong Kong exemplifies the former colony's dilemmatic “in-betweenness” and temporal inconclusiveness, which create an open discursive space that invites ideological investments by powerful symbolic stakeholders.
This article presents a preliminary, revised life history of Punta Laguna, Yucatan, Mexico, and considers in detail the site's relationship to nearby communities. More specifically, this article presents the results of a type-variety analysis of the cumulative palimpsest of ceramics excavated at the site between 2017 and 2022. Unlike initial studies conducted in the 1980s, the current study suggests that Maya peoples occupied Punta Laguna continuously or recurringly from 600/300 b.c. through a.d. 1500/1550. Punta Laguna is therefore usefully understood as a persistent place. By offering a composite life history of Punta Laguna, this article aims to augment current understandings of the complex social, political, and economic landscape of the northeastern Yucatan Peninsula. It also considers the utility of archaeological studies of persistent places to scholarship on urban sustainability and suggests that research investigating the connections between early occupation and site longevity may prove a fruitful avenue of study. Finally, this article argues that investigations of persistent places may provide a counterweight to the more common focus on collapse and thereby offer a more comprehensive understanding of the Maya past—one that emphasizes the vitality of the Maya present.
We extend a recent argument of Kahn, Narayanan and Park ((2021) Proceedings of the AMS 149 3201–3208) about the threshold for the appearance of the square of a Hamilton cycle to other spanning structures. In particular, for any spanning graph, we give a sufficient condition under which we may determine its threshold. As an application, we find the threshold for a set of cyclically ordered copies of $C_4$ that span the entire vertex set, so that any two consecutive copies overlap in exactly one edge and all overlapping edges are disjoint. This answers a question of Frieze. We also determine the threshold for edge-overlapping spanning $K_r$-cycles.
We prove that if a unimodular random graph is almost surely planar and has finite expected degree, then it has a combinatorial embedding into the plane which is also unimodular. This implies the claim in the title immediately by a theorem of Angel, Hutchcroft, Nachmias and Ray [2]. Our unimodular embedding also implies that all the dichotomy results of [2] about unimodular maps extend in the one-ended case to unimodular random planar graphs.
This paper describes the methodology used to analyse oscillations of foils of a wide range of aspect ratios, 0.5 ≤ AR ≤ 4, and Reynolds numbers, 104 ≤ Re ≤ 105, for energy harvesting purposes. The foils were fixed at their trailing edge, and their dynamical behaviour was captured as the wind speed was varied. The foil response was then analysed as a function of velocity, Reynolds number, oscillation amplitude and frequency. Additionally, the forces and moments acting on the foils were measured, utilising an aerodynamic scale, designed and built in-house. An empirical power generation equation was derived to determine the foil characteristics for maximum energy harvesting production. The results show that a flexible foil with AR = 3 with oscillations in the large-amplitude regime is the most effective for energy harvesting.
Supervised machine learning is an increasingly popular tool for analyzing large political text corpora. The main disadvantage of supervised machine learning is the need for thousands of manually annotated training data points. This issue is particularly important in the social sciences where most new research questions require new training data for a new task tailored to the specific research question. This paper analyses how deep transfer learning can help address this challenge by accumulating “prior knowledge” in language models. Models like BERT can learn statistical language patterns through pre-training (“language knowledge”), and reliance on task-specific data can be reduced by training on universal tasks like natural language inference (NLI; “task knowledge”). We demonstrate the benefits of transfer learning on a wide range of eight tasks. Across these eight tasks, our BERT-NLI model fine-tuned on 100 to 2,500 texts performs on average 10.7 to 18.3 percentage points better than classical models without transfer learning. Our study indicates that BERT-NLI fine-tuned on 500 texts achieves similar performance as classical models trained on around 5,000 texts. Moreover, we show that transfer learning works particularly well on imbalanced data. We conclude by discussing limitations of transfer learning and by outlining new opportunities for political science research.
This article interrogates the concept of legal pluralism, as it currently tends to function within contemporary legal and historical scholarship. It argues that the concept of legal pluralism cannot ‘liberate’ positivist analytical legal theory from monist (municipal, state-centric, etc.) straightjackets, but rather itself presumes the primacy of centralized state-issued law—at the same time as masking that primacy within a pluralist discourse. The concept of legal pluralism should be properly understood—and analyzed—as part of the mythology of modern law, not as an alternative to it. The first two sections develop this argument via a critical tour of legal-pluralist historiography, focusing on 1986 to the present day. The final section then moves on to explore what is at stake for the pre-modern historian when they apply (modern) concept(s) of legal pluralism to try to explain the multiplicity of legal orders that they invariably encounter in their own source material.
A standard text-as-data workflow in the social sciences involves identifying a set of documents to be labeled, selecting a random sample of them to label using research assistants, training a supervised learner to label the remaining documents, and validating that model’s performance using standard accuracy metrics. The most resource-intensive component of this is the hand-labeling: carefully reading documents, training research assistants, and paying human coders to label documents in duplicate or more. We show that hand-coding an algorithmically selected rather than a simple-random sample can improve model performance above baseline by as much as 50%, or reduce hand-coding costs by up to two-thirds, in applications predicting (1) U.S. executive-order significance and (2) financial sentiment on social media. We accompany this manuscript with open-source software to implement these tools, which we hope can make supervised learning cheaper and more accessible to researchers.
Language learner anxiety—and emotions in general—has constantly attracted academic attention in the second language acquisition (SLA) field for almost 40 years (Plonsky et al., 2022). However, within the context of the foreign language classroom, epistemic emotions remain understudied, despite their demonstrated effects on performance (D'Mello et al., 2014) and learners’ cognitive processes (Muis et al., 2018a). Epistemic emotions are academic emotions that “relate to knowledge-generating qualities of cognitive tasks and activities” (Pekrun et al., 2017, p. 1268). Their object focus lies in the generation of knowledge (Vogl et al., 2019a) and therefore are prominent during learning activities in academic settings. Recent research in SLA shows that epistemic emotions play a considerable role in instructed language learning (Fraschini, 2023; Nakamura et al., 2022). This current study analyses how two common epistemic emotions—epistemic anxiety and curiosity—mediate the link between a learner's perceived value and intended effort. Empirical data was collected using a tailor-designed survey administered to learners of Korean as a foreign language enrolled in a hybrid university course. Results show that epistemic anxiety and curiosity are independent of each other and coexist during language learning tasks. Furthermore, both epistemic emotions significantly correlate to a learner's perceived value of language learning, with opposite effects. While learners with a higher perceived value tend to be more curious, they also appear less anxious. These results are further discussed considering teachers’ and learners’ characteristics and in relation to theoretical and pedagogical implications for the language classroom.
Current psychological trauma-focused interventions have left a gap for individuals who may not be ready for trauma-focused treatment and/or who present with other forms of clinically significant distress, such as subthreshold post-traumatic stress disorder (PTSD). Emotion regulation is a possible transdiagnostic mechanism of change that may promote and maintain some of the varied mental health problems related to trauma exposure.
Aims:
This study examines the feasibility and initial impact of two brief emotion regulation skill trainings targeting different processes hypothesized to reduce trauma-related problems, compared with an active control.
Method:
Subjects (n = 156) were randomized to receive one of three brief internet-based trainings: (1) skill training on accepting emotions, (2) skill training on changing emotions, or (3) stress psychoeducation (control). Participants completed measures of emotion regulation, mindfulness, and affect intensity 24 hours pre- and immediately post-training.
Results:
Results suggested that a brief internet-based skills training programme was feasible and acceptable, with 91.9% completing the training programme to which they were randomized. Results showed that participants in all conditions demonstrated significant decreases in emotion regulation problems over time; yet these improvements did not vary by condition. Participants in the Change condition with higher PTSD symptoms were significantly more likely to have greater increases in positive affect compared with those with lower PTSD symptoms.
Conclusions:
Although the three conditions did not show different outcomes, all three brief internet-delivered trainings were feasible. Results provide direction for future studies to evaluate the delivery of emotion regulation skills in individuals with trauma-related distress.
