We study a pair consisting of a smooth 3-fold defined over an algebraically closed field and a “general” ${\Bbb R}$-ideal. We show that the minimal log discrepancy (“mld” for short) of every such a pair is computed by a prime divisor obtained by at most two weighted blow-ups. This bound is regarded as a weighted blow-up version of Mustaţă–Nakamura’s conjecture. We also show that if the mld of such a pair is not less than 1, then it is computed by at most one weighted blow-up. As a consequence, ACC of mld holds for such pairs.
The Amsterdam Instrumental Activities of Daily Living Questionnaire (A-IADL-Q) is well validated and commonly used to assess difficulties in everyday functioning regarding dementia. To facilitate interpretation and clinical implementation across different European countries, we aim to provide normative data and a diagnostic cutoff for dementia.
Methods:
Cross-sectional data from Dutch Brain Research Registry (N = 1,064; mean (M) age = 62 ± 11 year; 69.5% female), European Medial Information Framework-Alzheimer’s Disease 90 + (N = 63; Mage = 92 ± 2 year; 52.4% female), and European Prevention of Alzheimer’s Dementia Longitudinal Cohort Study (N = 247; Mage = 63 ± 7 year; 72.1% female) were used. The generalized additive models for location, scale, and shape framework were used to obtain normative values (Z-scores). The beta distribution was applied, and combinations of age, sex, and educational attainment were modeled. The optimal cutoff for dementia was calculated using area under receiver operating curves (AUC-ROC) and Youden Index, using data from Amsterdam Dementia Cohort (N = 2,511, Mage = 64 ± 8 year, 44.4% female).
Results:
The best normative model accounted for a cubic-like decrease of IADL performance with age that was more pronounced in low compared to medium/high educational attainment. The cutoff for dementia was 1.85 standard deviation below the population mean (AUC = 0.97; 95% CI [0.97–0.98]).
Conclusion:
We provide regression-based norms for A-IADL-Q and a diagnostic cutoff for dementia, which help improve clinical assessment of IADL performance across European countries.
We examine the vapour cloud of a pure liquid evaporating from a millimetric cylindrical well/cavity/aperture. This is accomplished by injecting the liquid up a vertical pipe towards its outlet onto a horizontal substrate. The injection is halted before the liquid surpasses the substrate level. The resulting final state is a meniscus at or near the pipe's end. The analysis is realised by vapour interferometry (side view over the substrate) closely intertwined with simulations (including Stefan flow), which also help to fill up certain gaps in the measurements and provide computed evaporation rates. Comparison with experiment is facilitated by converting the computed vapour clouds into interferometric images, especially helpful when an inverse (Abel-type) conversion is difficult. Experiments are conducted in both microgravity (via parabolic flights) and ground conditions, thus enabling direct assessment of the role of gravity. The contrast is accentuated by a working liquid with heavy vapour (refrigerant HFE-7100), when instead of being flattened on ground the vapour cloud assumes a roughly hemispherical shape in microgravity. Furthermore, a non-trivial vapour-cloud response to the flight ${\rm g}$-jitter (residual gravity oscillations) is unveiled, ${\rm g}$-jitter vibrations posing a challenge for interferometry itself. A number of undesired but curious side issues are revealed. One concerns vapour formed deep inside the pipe during rapid injection and subsequently ejected into the field of view, which is detected experimentally and quantified in terms of vapour Taylor dispersion in the pipe. Others are an injection volume anomaly and parasitic postinjection specifically observed in microgravity conditions.
State violence against Belarusian women involved in protest activities after the fraudulent presidential election in 2020 and onward has been unprecedented in the country’s history. Women’s activism has challenged the patriarchal authoritarian regime, which was ill-prepared to deal with women. However, after a short period of adaptation by the repressive institutions, women became their “special clients.” With reference to gender-sensitive academic research, we investigate diverse forms of state violence against women and analyze how they perceive their experiences of incarceration for political reasons. This article is based on available datasets, a series of nine semi-structured interviews, and insights from participant observation. The research reveals that Belarusian women incarcerated for political reasons fall under the “demanding clients” category: they comprehensively challenge the state-sponsored brutal patriarchy and expect the repressive apparatus to meet their specific needs. These women experience multidimensional physical discomfort and psychological pressure, including targeted offensive and dehumanizing elements. At the same time, incarcerated women do not feel ostracized by society; they share the feeling that their “crimes” are supported by civil society, and they endure the pains of punishment as targeted violence from a state fighting cynically for its own survival.
This article introduces the forum on food shortages during the post-Habsburg transition in the Bohemian Lands and Slovenia. Using examples from these regions, it first outlines the food crisis that developed during World War I and contributed to the internal disintegration of the Habsburg Empire. The article then turns to Czechoslovakia and Yugoslavia, successor states which, despite their victorious status and optimistic prospects for the future, had to contend with food shortages that lasted well beyond 1918. Shortages remained one of the main challenges to the consolidation of these newly formed states. Finally, and most importantly, the article provides an overview of the state of the art in Czech, Slovene, and international historiography, identifies gaps in knowledge, and presents our approach to the topic.
We provide an overview of transnational non-state actors and their agency that shape today’s out-of-home childcare around the world, specifically institutional residential childcare. Based on existing studies and desktop research, we reveal a broad range of complexly inter-related for-profit and non-profit actors promoting diverse, often conflicting policies and practices – with ambiguous implications for children in care. We focus on secular and faith-based international non-governmental organisations, transnational companies, private regulators, and individuals. Many of them promote family- and community-based care, yet many others support orphanages and other forms of institutional care. The growing number of transnational actors in residential childcare, the emergence of private regulatory frameworks, the advance of market-based, for-profit players, and the involvement of well-resourced religious communities make the future of child institutionalisation uncertain. We discuss how this transnational agency compares with other policy fields and propose directions for future investigations of how transnationalism impacts children in care.
This article illustrates the socioeconomic background of rural political discontent in the post-imperial Yugoslav border region Prekmurje. The author argues that during the post-Habsburg political transition and ensuing social transformation, the fundamental lack of loyalty to the Yugoslav state among an important segment of the rural population of Prekmurje was rooted in insufficient access to food. Documents of court proceedings, official state reports, and findings of individuals with deep understandings of the situation on the ground reveal that this rural political mobilization was not so much a reflection of Hungarian propaganda or a “lack of appropriate national identification” among the local population—although, of course, these two factors cannot be ignored in a contested and linguistically and ethnically diverse region—but rather an outcome of the impoverishment of large sections of the peasant population.
In the last century, beauty has not often found itself enlisted in struggles for justice. As Alexander Nehemas recounts, beauty's severance from goodness and truth in the modern period renders beauty dangerous, its charm easily wielded as an instrument of oppression in the hands of the powerful. While some scholars have argued for a return to the pre-modern metaphysics that binds beauty to truth and goodness, the abuse of beauty is not simply a modern phenomenon, and its resistance requires more than a pre-modern solution. Beauty is eschatological; thus its abuse points to a failure to order it properly to its eschatological end. This article will argue that the abuse of beauty can be resisted not by spiritualising beauty, but by ordering physical beauty to its eschatological end. This end is most clearly seen in the ascended Christ, with his beautiful body that is human, wounded and hidden.
Using a 1-year longitudinal design, we examined the role of personal demands and personal resources in long-term health impairment and motivational processes among master students. Based on the job demands-resources theory and transactional model of stress, we hypothesized that students’ personal demands (i.e., irrational performance demands, awfulizing and irrational need for control) predict perceived study demands one year later, and indirectly relate to burnout. Furthermore, we predicted that personal resources indirectly associate with study engagement via students’ perceived study resources one year later. These hypotheses were tested in a sample of Dutch master students (N = 220 at T1 and T2) using structural equation modelling. As hypothesized, personal demands and personal resources at T1 predicted study demands and study resources one year later (T2, β = .25–.42, p <. 05), respectively. Study-home interference [study demand] mediated the association between personal demands and burnout (β = .08, p = .029), whereas opportunities for development [study resource] mediated the association between personal resources and study engagement (β = .08, p = .014). Hence, personal demands and personal resources relate indirectly to students’ burnout and engagement one year later via a heightened level of specific study demands and study resources. Accordingly, the present research expands the propositions of the JD-R Theory by proposing personal demands as a relevant factor for students’ long-term well-being.
We conduct a systematic study of the Ehrhart theory of certain slices of rectangular prisms. Our polytopes are generalizations of the hypersimplex and are contained in the larger class of polypositroids introduced by Lam and Postnikov; moreover, they coincide with polymatroids satisfying the strong exchange property up to an affinity. We give a combinatorial formula for all the Ehrhart coefficients in terms of the number of weighted permutations satisfying certain compatibility properties. This result proves that all these polytopes are Ehrhart positive. Additionally, via an extension of a result by Early and Kim, we give a combinatorial interpretation for all the coefficients of the $h^*$-polynomial. All of our results provide a combinatorial understanding of the Hilbert functions and the h-vectors of all algebras of Veronese type, a problem that had remained elusive up to this point. A variety of applications are discussed, including expressions for the volumes of these slices of prisms as weighted combinations of Eulerian numbers; some extensions of Laplace’s result on the combinatorial interpretation of the volume of the hypersimplex; a multivariate generalization of the flag Eulerian numbers and refinements; and a short proof of the Ehrhart positivity of the independence polytope of all uniform matroids.
Excavations at the site of Tell el-Retaba since 2007 have revealed an extensive settlement and associated material culture dating from the Third Intermediate Period (1070–664 BC). This work represents the only large-scale investigation into domestic archaeology from this period in Egypt and the results offer important insights into aspects of urban life for an under-studied phase of Egyptian history.
Women as a social category have been the subject of numerous recent studies considering their lived experience in the Late Antique and Byzantine Mediterranean. However, their representation in the narrative sources continues to shape modern reconstructions of women's agency within their social and economic contexts, often with unsatisfactory results. Building on the twentieth-century sociologist Pierre Bourdieu's model of social capital, this article will use the documentary papyri from Egypt to suggest a paradigm in which the agency of individual women can be viewed and incorporated into micro-historical narratives of the patriarchal society of Late Antiquity.
Throughout Iconoclasm the imperial icon was used in iconophile writings as the major argument in support of icon veneration. It included images of the emperor reproduced in various media and even panel portraits. Although the latter have not survived, they were real objects with a strong presence in the Byzantine system of visual communication. This paper will show that that the role of the imperial icon in Byzantine imagery and image theory was closely connected to the perception of the emperor and of the sacred imperial power in Byzantium.
Codex Atheniensis 211 is the earliest surviving illustrated Chrysostomic anthology. Its unique and sophisticated illustration still puzzles and fascinates scholars. The relative chronology of the manuscript fluctuates between the end of the ninth century and the first half of the tenth, while its provenance remains to this day unspecified. In an attempt to illuminate the circumstances of its creation, this study engages with the examination of a unique homily and its illustration. In my view, the people responsible for the selection of the sermon and the design of its illustration conceived it as a meaningful re-contextualization of the homily's original delivery; the historical background of fifth-century Constantinople served as a springboard for the articulation of an eloquent visual comment on current public issues in the Byzantine capital.
How do governing actors in international politics become legitimised? Current approaches to the study of legitimation do not fully account for the complexities of governance in contemporary international and global politics because they pre-specify ‘sources’ of legitimacy and treat change in audience expectations towards rightful rule as exogenous to legitimation processes. Instead, this article synthesises existing models of legitimation with relational theory to argue that constellations of institutional complexities necessitate an analytical focus on audiences and their expectations as embedded in governance networks. It then provides a relational theory of legitimation, emphasising the mechanisms undergirding legitimation: legitimation should be conceptualised as a process of congruence-finding between actors’ normative expectations. A governance relation might be influenced towards greater or lesser congruence via several mechanisms working at the level of the relation and the wider network, with more congruence giving rise to stabler governance practices. In this way, the theory builds upon legitimation scholarship by developing pathways to investigate legitimation across the varied contexts of international politics: it avoids a normative background theory of legitimacy sources and provides an improved framework for understanding change in the legitimacy of institutions over time by considering endogenous mechanisms of legitimation.
Los otáridos fueron recursos críticos para muchas sociedades costeras de Sudamérica. Se han propuesto diferentes estrategias para la explotación de esta presa, que parten principalmente de considerar parámetros ecológicos sobre su distribución y comportamiento y que pueden ser examinados según la especie, la edad y el sexo de los especímenes identificados en el registro arqueológico. En este trabajo partimos de estos criterios para analizar la representación de restos de otáridos en conjuntos zooarqueológicos de diferentes espacios del sur de Tierra del Fuego. Los resultados indican que se implementaron estrategias similares de explotación en toda el área, aún donde se presumen condiciones geográficas, culturales y ecológicas diferentes en la relación humano-otárido. A partir de los resultados se examinan algunos aspectos analíticos sobre la identificación zooarqueológica de individuos lactantes y la caracterización de la forma de explotación de esta presa según el tipo de apostadero y su distribución en el ambiente actual.
Czechoslovakia as a victorious, yet still fragile post-imperial state, considered censorship and state propaganda to be a necessary tool to secure its legitimacy at home and abroad. From the very beginning, Czechoslovakia defined itself as a democracy with freedom of speech as its basic principle, yet at the same time, it had to deal with inner fragility and outer vulnerabilities. The strategic agenda of people's nutrition, which was closely associated with the perceived competence of state institutions, serves as a litmus test for the state's regulation of press and public speech and the implementation of republican practices and acceptable limits on public discourse. This study analyzes how the new republican state regulated information on food supply shortcomings in the press and at public gatherings. It argues that Czechoslovakia maintained the prewar Habsburg practices of censorship; however, instead of the vaguely defined public interest of the multinational monarchy, it was now used to protect the public interest of “the national state of the Czechoslovaks.” This study analyzes how the government thought about the consistency of its communication during the postwar (supply) crisis, and thus also options of how to shape a clear and positive brand of the state.
