Do locals discriminate against themselves by favoring foreigners with higher expected purchasing power? Drawing on theories of prejudice, discrimination, and colonialism, I argue that in colonized and post-colonial countries, local home sellers discriminate against local potential homebuyers while favoring foreigners with expected higher purchasing power, anticipating a more profitable transaction. I support this argument with evidence from a preregistered online audit study targeting discriminatory attitudes toward local home buyers. In the study, fictitious home buyers with distinctive language and ethnic names emailed 1,512 home sellers (realtors and homeowners) across all municipalities in Puerto Rico. Home sellers reported more houses available to Americans and invited them to more house showings than Puerto Ricans. My estimates indicate that ethnic discrimination exists in the Puerto Rican housing market. These findings provide new insights into ethnic dynamics in colonized and post-colonial societies and underscore concerns about recent legislation that turned Puerto Rico into a tax haven.
The objective of this study was to evaluate graft success, hearing improvement, and complications following perichondrium–cartilage underlay myringoplasty without external auditory canal packing.
Methods
In this prospective study, we examined 37 ears of 37 patients with large perforations who underwent endoscopic perichondrium–cartilage underlay myringoplasty without external auditory canal packing. Patients were followed up for six months.
Results
At one week after the surgery, the graft was in situ in 35 (94.6 per cent) ears. At 2–3 weeks post-surgery, among the 35 ears without infection, the graft was in situ in 29 (82.9 per cent) ears, and the graft was bulging in 6 (17.1 per cent) ears. At six months post-surgery, the graft success rate was 94.6 per cent (35 of 37 ears). No graft lateralisation or graft medialisation was encountered during the follow-up period.
Conclusion
The absence of external auditory canal packing did not affect the graft success or hearing improvement following underlay myringoplasty. Thus, external auditory canal packing does not appear to be necessary for underlay myringoplasty.
Today, Neolithic circular enclosures are generally regarded as evidence of the first monumental architecture in Europe. They are undoubtedly a topical subject in Neolithic research and also attract great interest from a broader audience. This has not always been the case. Just over 40 years ago, the few examples known then, mainly from Bavaria and Bohemia, were regarded as exotic and of no particular importance for the cultural-historical assessment of early farming societies in Europe. Thanks to aerial archaeology, the number of known sites increased rapidly in the 1970s and 1980s in Bavaria and Lower Austria. This has also been the case, since the 1990s, in East Germany and other countries of the former Eastern Bloc when political change made systematic prospecting flights possible. In addition, the development of geophysical prospection methods provided new insights into the structure and landscapes into which the enclosures were embedded. Finally, the increasing number of rescue excavations and large-scale scientific excavations have contributed to a better understanding of such sites as a characteristic component of Middle Neolithic societies in Central Europe.
Vanishing white matter syndrome is one of the leukoencephalopathies caused by recessive mutations in gene EIF2B1–5. Adult-onset EIF2B-pathies (clinical onset after age 16 years) have been reported to be less common.
Objective:
Description of the clinical, imaging and genetic profile of adult-onset EIF2B-pathies and comparison of Indian cohort with Asian and European cohorts.
Methods:
Report of two cases of adult-onset EIF2B-pathies and a comprehensive review of genetically confirmed adult-onset EIF2B-pathies since 2001 from Indian, Asian and European cohorts.
Results:
Two patients were females, with median age at presentation of 25.5 years (24–27 years) and onset at 19 years (18–20 years). The median duration of symptoms was 6.5 years (6–7 years). Both had cerebellar ataxia, spasticity, cognitive impairment and bladder involvement. Brain magnetic resonance imaging (MRI) showed leukoencephalopathy with rarefaction in both patients and corpus callosum involvement in one patient. Genetics showed homozygous missense variant in the EIF2B3 gene in both patients. The Indian cohort of seven patients had similar clinical and radiological features and common variants in EIF2B3 (n = 4). The Asian cohort had 24 cases, and the European cohort had 61 cases with similar clinical features, radiological features and common variants in EIF2B5.
Conclusion:
Adult-onset EIF2B-pathies have a distinct clinical profile of female predominance with cerebellar ataxia, spasticity and cognitive decline as the commonest triad of clinical manifestations and leukoencephalopathy with rarefaction on brain MRI. Variants in EIF2B5 were common in the Asian and European cohorts and EIF2B3 in the Indian cohort.
How can political scientists rigorously evaluate the predictive power of theories? Many peer-reviewed political science articles include predictions about future outcomes, and scholars make predictions on social media and other public forums. The prevalence of predictions suggests that scholars recognize the utility of leveraging theories for this purpose; however, the predictions often are not made in a manner that allows for rigorously evaluating their accuracy. Building on the increasing popularity of study preregistration in the social sciences, this article proposes “prediction registration” as a means for scholars to publish falsifiable, systematic, and verifiable theory-based predictions. Increasing the rigor of predictive theory testing can advance often-circular debates about accuracy and presents a “win-win” for scholars who aim to test the predictive power of theories. With a more rigorous approach, correct predictions would better demonstrate a theory’s ability to forecast outcomes, and missed predictions would reveal information that can be used to calibrate the theory.

It highlights response impact and priorities around training, partnerships, best practice sharing, and officer development that ready USPHS for 21st century demands. Attendees will gain insight into how specialized USPHS emergency preparedness makes it indispensable for advancing health security alongside allies globally.
The aim of this study was to compare the internet and social media use of teenagers with hearing loss with that of their normal hearing peers.
Methods
The study included 27 hearing-impaired and 27 normal-hearing peers (12–18 years). The Social Media Attitude Scale, the Internet Use Purposes Scale, University of California, Los Angeles Loneliness Scale and the Problematic Internet Use Scale were used to compare hearing-loss and normal-hearing groups.
Results
The social isolation subscale and Social Media Attitude Scale total score differed between groups (p = 0.001 and p = 0.048, respectively). Internet Use Purposes Scale education subscale differences were statistically significant (p = 0.042). Negative consequences (p = 0.007), excessive use (p = 0.021) and Problematic Internet Use Scale total score (p = 0.005) differed significantly. The University of California, Los Angeles Loneliness Scale had a moderate negative connection with the Problematic Internet Use Scale's social benefit/comfort subscale and total score (r = 0.369, p = 0.006 and r = −0.309, p = 0.023, respectively).
Conclusion
While adolescents with hearing loss have limited online educational resources, problematic internet use is a concern. When overused, the internet can reduce loneliness, but it can also have harmful consequences.
This article argues that Andocides’ speech On His Return (Andocides 2) makes use of themes drawn from tragedy, including a near-quotation from Sophocles, in order to present the orator as deserving of pity and forgiveness. This neglected speech is therefore an ingenious work of rhetoric in its creation of ēthos and evocation of pathos. Moreover, it is a key document for the development of religious argumentation in the Athenian courts, and for the early reception of Sophocles. This also affects our interpretation of the two extant speeches from Andocides’ later trial in ca. 400, Against Andocides ([Lysias] 6) and On the Mysteries (Andocides 1), which both develop similar tragic themes in new directions.
This study measured the effectiveness of an in-house designed, cast silicone airway model in addressing the lack of easily accessible, validated transoral laser microsurgery simulation models.
Methods
Participants performed resection of two marked vocal fold lesions on the model. The model underwent face, content and construct validation assessment using a five-point Likert scale questionnaire measuring the mean resection time for each lesion and the completeness of lesion excision. Comparative analyses were performed for these measures.
Results
Thirteen otolaryngologists participated in this study. The model achieved validation threshold on all face and content measures (median, ≥4). Construct validation was demonstrated by the improvement in mean resection time between lesions one and two (86 vs 54 seconds, W = 11, p = 0.017). The mean resection time was lower amongst more senior otolaryngologists (61.5 vs 107.1 seconds, W = 11, p = 0.017).
Conclusion
This synthetic silicone model is a low-cost, easily reproducible, high-fidelity synthetic airway model, demonstrating face, content and construct validity.
It is impossible to understand the phenomenon of disinformation without unraveling the more perplexing notion of “truth.” This article explores how a Bulgarian psychic or prophet named Baba Vanga (1911–1996) became one of the most noteworthy mediums of “truth” in twentieth- and twenty-first-century Russian imagination. With Bulgarian-Russian transnational ties as context, we trace how belief in Baba Vanga’s abilities and prophecies was propagated by witnesses via word-of-mouth, newspaper articles, books, TV programming, and the internet. We periodize the ways Vanga secured a place in Russian “truth worlds,” drawing upon both science and religion or a conglomeration of both. We look deeper into the origins and more recent circulation of a purported Vanga prophecy from 1979: namely, that Russia would rise to be the ruler of the world. The dissemination of this message, we argue, is not a Russian state plot to bolster aspirations in Ukraine and its standoff with the West. Instead it has been transmitted in far more fragmented and mediated ways and even countered by the Russian Orthodox Church. A deeper pondering of these mediations of Baba Vanga can help us better understand what we call the “post”-truth world, in which truth is crafted by online “posts.” In contrast to the notion of “post-truth” that posits a dearth of truth, our concept of “post”-truth recognizes that truth is not just in unprecedented excess today but is built through a complex and participatory bricolage that uses science and religion to build shared realities as never before in history.
Do Indigenous peoples in present-day Canada display lower levels of diffuse support than non-Indigenous settlers? Given settler colonial relations (both historic and contemporary) and Indigenous peoples’ own political thought, we can expect that Indigenous peoples would have even lower perceptions of state legitimacy than non-Indigenous peoples. However, there are conflicting expectations regarding whether the descriptive representation of Indigenous peoples in settler institutions is likely to make a difference: on one hand, Indigenous people may see themselves reflected in these institutions and consequently feel better represented; on the other hand, these forms of representation do not challenge the underlying colonial nature of these institutions. Using data from the 2019 and 2021 Canadian Election Studies, our statistical analysis demonstrates that: (1) diffuse support is significantly lower among Indigenous peoples than non-Indigenous peoples, including people of color; (2) Indigenous respondents across multiple peoples have similarly low levels of diffuse support, and (3) being represented by an Indigenous Member of Parliament does not change the levels of diffuse support among Indigenous peoples. Overall, our research highlights the outstanding challenges to achieving reconciliation through the Canadian state and points to ways large-N analyses may be made more robust.
This article discusses sceptical arguments about measurement scales. Measurement scales are part of a promising agenda of openness, transparency and patient and public involvement (PPI) in medical research, but have received critical, sometimes hostile attention from anthropologists. This is because scales repackage localised cultural assumptions about distress as something universal and pan-human and have the capacity to reshape people's interior lives in unhelpful, possibly harmful ways. We take as an example the Patient Health Questionnaire-9 (PHQ-9). Use of the PHQ-9 is currently mandated by major funders. But its history suggests flawed PPI and a lack of openness. The article suggests a constructive role for anthropology in mental health research, using ethnographic evidence and theory to show how, although they have their uses, mental health scales should not be regarded as inert or harmless.
Microvortex generators (MVGs) are a promising solution to control shock wave/turbulent boundary layer interactions (SBLIs), especially in supersonic inlets. In this study, we examine the effects of a microramp vortex generator on an SBLI generated by an oblique shock wave and a turbulent boundary layer using direct numerical simulations (DNSs). Two cases, with and without the presence of a microramp, are compared in terms of their mean and unsteady flow features at free-stream Mach number equal to 2 and friction Reynolds number at the inviscid shock impingement equal to 600. The long integration period allows us to assess how microramps affect the typical low-frequency unsteadiness observed in SBLIs, and the data generated may serve as a reference for simulations of lower fidelity or reduced order models. The analysis shows that the three-dimensional microramp wake alters the interaction region dramatically, inducing a significant spanwise modulation and topology change of the separation. For example, tornado-like structures redistribute the flow in both the spanwise and wall-normal directions inside the recirculation region. The increase in momentum close to the wall by the ramp vortices effectively delays the onset of the separation and, thus, the separation length, but at the same time leads to a significant increase in the intensity of the wall-pressure fluctuations. We then characterise the mutual interaction between the arch-like vortices around the ramp wake and the SBLI. The specific spanwise vorticity shows that these vortices follow the edge of the separation and their intensity, apart from mean compressibility effects, is not affected by the shocks. The shocks, instead, are deformed in shape by the periodic impingement of the vortices, although the spectral analysis did not reveal any significant trace of their shedding frequency in the separation region. These Kelvin–Helmholtz vortices, however, may be relevant in the closure of the separation bubble. Fourier analysis also shows a constant increase, in both value and magnitude, in the low-frequency peak all along the span, suggesting that the motion of the separation shock remains coherent while being disturbed by the arch-like vortices and oscillating at a higher frequency in absolute terms.
This article revisits the mainstream scholarly view that the Greek Hestia is the least anthropomorphic deity among the Olympians, an idea that owes much to a short reference to her in Plato’s Phaedrus. The analysis is based on textual and visual sources from the Archaic period: I first review two references to Hestia in early hexameter poetry, in Hesiod’s Theogony and in the Homeric Hymn to Aphrodite, before turning to the depiction of her in two early Attic black-figure vases, the Sophilos dinos at the British Museum and the François vase, which have been neglected in discussing Hestia’s anthropomorphic nature in early Greek thought. While the study of individual Greek gods has returned to the fore in the field of Greek religion in the last 20 years, it seems that not enough has changed in the current conceptualization of Hestia.
This edited volume by Mark Hauser and Julia Jong Haines aims to bring together local narratives within the context of the Indian Ocean in modern times, from c. AD 1500, and establish how these narratives can inform historical archaeology. As the editors highlight in the introductory chapter, historical archaeology has been greatly informed and inspired by the Atlantic world and its colonial histories. Here, they seek instead to foreground the Indian Ocean as a setting for historical archaeology in its own right. The authors use the long and deep history of interconnectedness and trade in this ocean as a basis for understanding more recent history, not just in light of colonial impact but through bottom-up approaches that focus on the local in the global. The case studies in this book and its overall theme are also part of the ongoing process to decentralise Europe in archaeological discourse. The book consists of 11 chapters, including an introductory chapter by Haines and Hauser and two commentaries. The majority of the case studies are from island East Africa or South India, which naturally limits the scope somewhat.
Since 2006, the Maricopa County Department of Public Health (MCDPH) has conducted routine surveillance of heat-associated deaths in the county. During that time, the number of deaths each year has been on the rise with 2022 numbers showing a 25% increase over 2021. Risk factors such as homelessness and alcohol and drug use have been shown to increase the risk of heat-associated death. During the summer of 2023, record-breaking heat in the metro-Phoenix area was widely reported. The MCDPH heat-associated death surveillance data was widely reported and used by policy makers to address extreme heat as a regional disaster. In this presentation participants will learn how heat-associated death surveillance has evolved over time to inform public health leaders and policy makers to the risk factors associated with poor outcomes from extreme heat. Participants will also understand how the data is shared at the local, national and international levels to inform extreme heat response activities.
Learning Objectives
Participants will learn how heat-associated death surveillance has evolved over time to inform public health leaders and policy makers of the risk factors associated with poor outcomes from extreme heat.
