Stone carvings in the context of Ottoman-era Greece play an important role in folklore studies as well as vernacular architecture. They are associated with the history of itinerant stonemasons, their beliefs, as well as the cultural milieu of the building’s owners. However, research rarely contextualises them within the framework of the Ottoman era and the identities of local people who dwelled in these spaces. This contribution first provides an overview of interpretations put forward by scholars in diverse disciplines (folklore, architecture, heritage). It then offers a critical evaluation of these interpretations according to contemporary trends in Ottoman studies, combining methodologies from multiple disciplines, ranging from innovative theoretical concepts to interpretive drawings and photogrammetry. To do so we focus on case studies from the Ottoman-era Bektashi heritage of Konitsa (north-west Greece), including the house of Hussein Sisko, Hamko’s mansion, as well as the gate of Hagios Nikolaos, which incorporates stone carvings from an Ottoman-era mansion in secondary use. We advance an interpretation of stone carvings as narratives reflecting the multiconfessional identities of the liminal Ottoman provinces of the south-west Balkans. Taking as an example the two series of stone carvings from the gates of Hamko’s mansion, we propose that they are best viewed as forms of storytelling, reflecting the identity of the Bektashi owners, as warriors of the faith, while also vaguely expressing the values of the in-house rituals of the same dervish network (tarikat). Furthermore, on the basis of a proposed rearrangement of the stone carvings at the church of Hagios Nikolaos to reflect their original meaning when they were adorning the mansion of Elmaz Bey, we argue for potential multiple and multiconfessional understandings of such carvings, as well as temporal connotations that are easily forgotten, arguments that open new research avenues when placed in the context of the body of literature that argues for the long-lasting survival of meanings.
Monitoring wildlife populations in vast, remote landscapes poses significant challenges for conservation and management, particularly when studying elusive species that range across inaccessible terrain. Traditional survey methods often prove impractical or insufficient in such environments, necessitating innovative technological solutions. This study evaluates the effectiveness of deep learning for automated Bactrian camel detection in drone imagery across the complex desert terrain of the Gobi Desert of Mongolia. Using YOLOv8 and a dataset of 1479 high-resolution drone-captured images of Bactrian camels, we developed and validated an automated detection system. Our model demonstrated strong detection performance with high precision and recall values across different environmental conditions. Scale-aware analysis revealed distinct performance patterns between medium- and small-scale detections, informing optimal drone flight parameters. The system maintained consistent processing efficiency across various batch sizes while preserving detection quality. These findings advance conservation monitoring capabilities for Bactrian camels and other wildlife in remote ecosystems, providing wildlife managers with an efficient tool to track population dynamics and inform conservation strategies in expansive, difficult-to-access habitats.
Sugar beet root damage at harvest promotes sucrose losses of circa 0.1 – 0.4 % day–1 in storage. However, root response to environmental stresses at harvest and their consequential rates of damage are not known. We investigated the effects of temperature and water stress at harvest on root resilience to damage and tissue strength. Water (irrigated to field capacity and non-irrigated) and temperature (cold and mild) treatments were imposed on physiologically mature sugar beet plants for seven weeks prior to and for three days after harvesting, respectively. Water status at harvest significantly affected relative water content (RWC) (p < 0.001), root weight (p < 0.001) and root width (p < 0.001). RWC was positively correlated to surface damage (R2 = 0.43, p = 0.02), root tip damage (R2 = 0.42, p = 0.03), tissue compression (R2 = 0.41, p = 0.05) and tissue puncture (R2 = 0.46, p = 0.01). Tissue damage was not affected by root tissue temperature of 4 °C compared to 12 °C. We conclude that sugar beet damage at harvest is not influenced by root temperatures over the range commonly observed in the UK and temperate production areas. However, higher water status at harvest, such as would be observed in a wet season, increases root tip and surface damage. These findings will help to inform optimum harvesting conditions to minimize sugar loss from the sugar beet crop.
Phase change materials (PCMs) hold considerable promise for thermal energy storage applications. However, designing a PCM system to meet a specific performance presents a formidable challenge, given the intricate influence of multiple factors on the performance. To address this challenge, we hereby develop a theoretical framework that elucidates the melting process of PCMs. By integrating stability analysis with theoretical modelling, we derive a transition criterion to demarcate different melting regimes, and subsequently formulate the melting curve that uniquely characterises the performance of an exemplary PCM system. This theoretical melting curve captures the key trends observed in experimental and numerical data across a broad parameter space, establishing a convenient and quantitative relationship between design parameters and system performance. Furthermore, we demonstrate the versatility of the theoretical framework across diverse configurations. Overall, our findings deepen the understanding of thermo-hydrodynamics in melting PCMs, thereby facilitating the evaluation, design and enhancement of PCM systems.
The American public is increasingly affectively polarized. A growing body of research has associated affective polarization with two key phenomena: ideological polarization and social group sorting. Although there is ample evidence that social group sorting, particularly along racial and ethnic lines, is driving Republicans’ affect toward the Democratic Party, it is not clear how it shapes Democrats’, particularly White Democrats’, feelings toward the predominantly White Republican Party. We propose a third model that bridges these two theoretical approaches, a racial ideology model that helps explain Democrats’ feelings toward the Republican Party. Specifically, we argue that Democrats increasingly dislike Republicans because Republicans are seen as standing in opposition to racially progressive policies. Using a preregistered conjoint experiment, we find that Americans across party lines see Republicans as opposing efforts to reduce racial inequality and that this perception is associated with negative affect toward the Republican Party among both White and non-White Democrats.
In this work, we study the effect of flow curvature, or angular momentum, on the propagation and trapping characteristics of near-inertial waves (NIWs) in a curved front. The curved front is idealised as a baroclinic vortex in cyclogeostrophic balance. Motivated by ocean observations, we employ a Gaussian base flow, which by construction possesses a shield of oppositely signed vorticity surrounding its core, and we consider both cyclonic and anticyclonic representations of this flow. Following two main assumptions, i.e. that (i) the horizontal wavelength of the NIW is smaller than the length scale of the background flow (the WKBJ approximation), and (ii) the vertical wavelength of the NIW is smaller than the radial distance of interest, we derive the NIW dispersion relation and discuss the group velocity and direction of energy propagation. We show that the curvature can (i) increase the critical depth and horizontal extent of the trapping region, (ii) reduce NIW activity at the centre of the anticyclonic vortex core and enhance it in the cyclonic shield surrounding the core for high curvatures, (iii) lead to NIW trapping in the anticyclonic shield surrounding the cyclonic core, and (iv) increase the available band of NIW frequencies that are trapped. The solutions from the ray-tracing method are supported by numerical solutions of the governing equations linearised about the cyclogeostrophic base state. Finally, these methods are applied to an idealised model of oceanic mesoscale Arctic eddies showing an increase in the critical depth of trapping. Our results – while applied to polar eddies – equally apply at lower latitudes in both oceans and atmospheres, highlighting the potential importance of flow curvature in controlling the propagation of NIW energy.
Shifts in food acquisition during the COVID-19 pandemic may have affected diet. Assessing changes in diet is needed to inform food assistance programs aimed at mitigating diet disparities during future crises. This longitudinal study assessed changes in diet among a low-income, racially diverse population from March-November 2020.
Methods
Survey data were collected from 291 adults living in Austin, TX. Multivariable ordinal logistic regression models assessed the relationship between changes in consumption of fresh, frozen, and canned fruits and vegetables (FV), and sugar-sweetened beverages (SSBs) and the following food acquisition factors: food security, difficulty finding food, food bank usage, and food shopping method.
Results
Adjusted models indicated individuals with consistent food insecurity had increased odds of reporting a higher category of consumption for frozen (aOR = 2.13, P < 0.05, CI:1.18-3.85) and canned (aOR = 4.04, P < 0.01, CI:2.27-7.20) FV and SSB (aOR = 3.01, P < 0.01, CI:1.65-5.51). Individuals who reported using a food bank were more likely to report increased consumption of frozen (aOR = 2.14, P < 0.05, CI:1.22-3.76) and canned FV (aOR = 2.91, P < 0.01, CI:1.69-4.99).
Conclusions
Shifts in food acquisition factors were associated with changes in diet. Findings demonstrate the need for more robust food assistance programs that specifically focus on all dimensions of food security.
This paper aims at reexamining external sustainability in a dynamic framework for nine European Monetary Union (EMU) countries during the period 1970–2021. We extend the approach of Bohn (1998) to a time-varying external reaction function. The main advantage of our empirical strategy is that it captures the dynamics of the external reaction function, by accounting for the main sources of heterogeneity among EMU countries and by including common factors like financial globalization and global risk aversion. To estimate the model, we employ a fully fledged state-space framework, which extends the simple model generally used in this literature to a panel-data time-varying parameter framework, combining fixed (common and country-specific) and varying components. Our results show an evident interplay between real and financial variables, the latter progressively increasing their importance. Although heterogeneous, the adjustment to external imbalances in most EU countries is jointly driven by the level reached in the stock of net foreign assets together with the degree of risk aversion and financial openness.
This paper considers the practical application of the metaphor of “good boundaries” for working towards better interspecies relationships and multispecies cultures. Engaged philosophical methods are employed in the context of the author’s family farm with attentiveness towards both multispecies and colonial politics. The analysis centers interspecies relational dynamics across a spectrum of liminal forms of life on “the property,” in the “homestead,” and under the guise of “stewardship.” The paper concludes that the metaphor of good boundaries helps to generate better multispecies entanglements by (i) growing our capacity for ecological thinking, (ii) directing our attention to moral failure, and, at times, (iii) disrupting anthropocentric colonial ideologies and practices.
Evaluate factors influencing the decision-making processes of school administrators and investigate the existence and use of emergency operations plans (EOPs) during the COVID-19 pandemic.
Methods
Using survey data representative of US K-12 public schools in 2022, the prevalence of 16 factors that influenced reporting school administrators’ COVID-19 prevention strategy implementation decision-making (Wave 4; N = 399) and the presence and use of school EOPs (Wave 5; N = 400) are presented overall and by urban-rural classification, poverty level, and school level. Qualitative interviews were conducted with a subset of school administrators and used thematic analysis to understand factors influencing implementation of prevention strategies and emergency preparedness.
Results
School district requirements or recommendations (81.6%) was the top reported factor influencing decisions on the use of COVID-19 prevention strategies. Although most schools created or updated their EOP during the 2021/2022 school year (78.1%), only 26.7% implemented or exercised an EOP during the COVID-19 pandemic. Themes from qualitative analysis focused on factors influencing the implementation of prevention strategies, limitations of current EOPs, and importance of continuous investment in school preparedness.
Conclusions
Investing in actions to improve schools’ capacity to respond to emergencies such as developing comprehensive EOPs, building partnerships, and defining roles and responsibilities is important.
Brain abscess is a rare but life-threatening complication in patients with cyanotic congenital heart disease (CHD), especially in those without prior corrective surgery.
Methods:
We report the case of a 36-year-old woman with unoperated cyanotic CHD who presented with neurological deficits. Diagnostic evaluation included cranial magnetic resonance imaging (MRI).
Results:
Imaging revealed a brain abscess. Contributing factors included chronic hypoxia, polycythaemia, and right-to-left shunting facilitating systemic circulation of infectious agents. The patient was treated with intravenous antibiotics and surgical drainage.
Conclusions:
This case highlights the elevated risk of brain abscess in uncorrected cyanotic CHD and underlines the importance of early recognition and timely management to avoid fatal outcomes.
Beginning with the opening-up reforms of Deng Xiaoping, the Chinese government has treated law as a central tool for regulating the economy and guiding institutional transformation. Over the decades, since 1949, China’s path to modernization has been marked by profound, experimental transformations that selectively combined foreign expertise with Chinese foundations. A key feature of this process has been China’s strategic adoption and adaptation of legal transplants. While initially a recipient of foreign legal models, China is now increasingly exporting its own approaches through the Belt and Road Initiative (BRI). This article examines how China’s engagement in shaping the legal and regulatory frameworks of host countries under the BRI differs from traditional models of legal transplants. Rather than imposing, China draws on its historical experience to adopt a pragmatic, adaptive strategy defined by three core characteristics: the combination of Chinese and Western practices; an emphasis on voluntariness tempered by asymmetrical power relations; and a prioritization of policy objectives over autonomous legal principles. While this strategy raises concerns about legal fragmentation and institutional coherence, it also fosters a space for legal pluralism, offering an alternative to the homogenization typically associated with Global North legal transplants.
This paper explores the theoretical and analytic possibilities of the concept of gharīb to offer a new understanding of regional displacement in what we know as the modern Middle East. The concept of gharīb (pl. ghurabāʾ) has accrued a wide range of meanings across time and space, including stranger, outcast, and exile, as well as pauper. By occupying the space between estrangement and poverty, the gharīb allows for an intersectional understanding of inequality, experienced by a growing number of marginalized and displaced communities in the Middle East. This paper honors the gharīb while making an analytic shift away from the category of the “refugee,” which has long been the dominant framework for personhood in the study of displacement. Combining genealogical analysis of the word gharīb with ethnographic accounts of displaced and impoverished communities in post-2011 Lebanon, I argue that legal binaries such as refugee versus citizen, and internal versus external displacement, have been further blurred against the backdrop of ongoing and interlocking forms of structural violence, inequality, and lack of protection for marginalized groups. The right to belong, therefore, is less about citizenry and more about a mode of social and economic poverty. This is particularly the case in the margins, where the repercussions of the ongoing crises are first and foremost felt. The gharīb, in contrast to such legal binaries, can be an analytic tool that allows us to delve deeper into the complexities of belonging, futurity, and rights without falling into the traps of methodological nationalism and top-down regional demarcations.
Legal, ethical, historical, cultural, and political questions in relation to African cultural heritage are increasingly the focal point of international, regional, and national debates. It is now widely recognized that African cultural disputes – often between African States (or State institutions) on the one hand, and Western States, State institutions and private actors on the other – are ripe for settlement, especially on the basis of law, including international law. This article focuses on international arbitration as a means for resolving African cultural heritage-related disputes and, for the first time analyses the benefits of all types of international arbitration (State-to-State arbitration, investment treaty arbitration and commercial (contract-based) arbitration) from the perspective of African States and actors in relation to the resolution of African cultural heritage disputes, which include disputes regarding the return of African cultural objects. This article examines for the first time the potential role of all types of arbitral proceedings ((i) State-to-State arbitration, (ii) international investment treaty arbitration (or, as often-called, Investor-State Dispute Settlement (ISDS)), and (iii) commercial arbitration) for the resolution of Africa-related cultural heritage disputes.
This article discusses data from a Romance variety spoken in the linguistic region of France referred to as the Croissant. When roots in this language exhibit a phonologically problematic right edge, the problem is treated differently depending on whether the stem is nominal or verbal. We propose that this unequal treatment reflects an underlying distinction: seemingly unsuffixed verbs are in fact underlyingly suffixed, whereas nouns are truly unsuffixed. The final consonant of the verbal stem is therefore not final underlyingly. It is claimed that this solution is preferable to relying on distinct grammars for nouns and verbs or assuming transderivational relations between words. The article also clarifies the purview of Strict CV, the framework that it is couched in. Strict CV is a theory of representations that defines well- and ill-formed structures, some of which are universal. It needs to be complemented by a theory of computation.
