In the present article, we describe what we call Intransparent-Gap Relatives (IGRs) in Japanese. In IGRs, a gap is located within the relative clause, and the head noun appears outside the relative clause. Unlike the standard head-external relatives, the gap in IGRs is not transparently associated with the head noun, but they are mediated through a metonymic relation. We propose a formal account of IGRs in terms of incremental parsing in Dynamic Syntax: an IGR string is processed in a left-to-right manner, and a semantic structure is progressively built up. This account unifies the standard head-external relatives and IGRs, relegating their differences to the ways in which the head noun is parsed and construed against the relative clause structure. Confirmation of this analysis comes from cross-constructional and cross-linguistic considerations. First, the analysis predicts that a metonymic reading is available in relatives but not in other rightward-displacement constructions, such as clefts and postposing. Second, the analysis suggests that IGRs are possible in languages such as Japanese and Korean, where the relative clause is processed before the head noun, but not in languages such as English and French, where the head noun is processed before the relative clause.
Historically, there have been two kinds of economic activities in northern Alaska. The first and oldest is the subsistence lifestyle of the Indigenous peoples. The second and more recent is the development of the oil and gas industry, which began in earnest in 1977 with the competition of the Trans-Alaskan Pipeline and construction of a new road, the Dalton Highway. Although first used only by commercial traffic for the oilfield, in 1994, the highway opened to the public and is now frequented by tourists travelling above the Arctic Circle. In this paper, we analyse the future of northern Alaska tourism by considering evolutionary economic geography and the area’s likely reduction in oil and gas activity. We consider how climate change may serve as a trigger, impacting tourism through the rise of last chance tourism, and conduct a scenario-based analysis. We argue that the oil and gas industry is likely to continue along its current path, exhausting accessible resources and innovating technology to push into new territories in the far north. However, should the culmination of extraneous factors render climate change a trigger, industry decline could be offset by investments that repurpose the area’s industrial heritage into tourism sites.
Mineral species are known to be heterogeneously distributed throughout the Earth such that a relatively small number of minerals make up a large proportion of the lithosphere while the majority of all known minerals are rare and have been identified at only a small number of locations that frequently exhibit high levels of species richness. Intuitive understandings of mineral scarcity and abundance are reconsidered through the characterisation of the quantitative aspects of spatio-temporal trends in new mineral discovery. Using data drawn from online mineralogical databases, it is found that the Earth's mineral hotspots exhibit an exponential distribution of species abundance, while those same mineral hotspots exhibit a power-law distribution in the number of minerals first recognised at those locations. That is, locations rich in first occurrences are extremely rare, even when considering only the Earth's most species-rich mineral locations. Global distributions of mineral scarcity and abundance can be estimated from the number of mineral-location pairs for each species reported in a database. Two-thirds of all known species have been reported from ten or fewer locations and the frequency distribution of these mineral-location pairs exhibit a power-law distribution that extends with increasing dispersion over several orders of magnitude of mineral abundance. Initially, nearly all minerals are first reported from only their type locality. Over time, additional occurrences of newly discovered minerals are reported at an average rate of one new location per mineral every 5.5 years. As a result, the percentage of minerals that were discovered in a given year that continue to be known only from their type locality is found to decline exponentially over time. However, a few minerals remain known from only their type locality for long periods, including some that were first identified in the 19th Century. Conversely, other recently identified minerals have been subsequently recognised at locations spanning a wide geographic range such that the number of minerals with cosmopolitan distributions is found to increase exponentially over time. Taken together, these several quantitative representations of mineral distributions lend structure and refinement to qualitative and intuitive notions of the scarcity and abundance of Earth's many minerals.
This study identifies the reasons for geodynamics variability of the coastal system within two cliff-shore sections of the southern Baltic Sea (SBS). The comparative analysis included distinct moraines and their foregrounds near the open sea (S1) and within the Gulf of Gdańsk (S2). Short-term trends indicate a direct link between landslide occurrence and increased cliff retreat. Long-term (total) values were obtained by developing the 4F MODEL for large-scale applications, based on the analysis of remote sensing and hydroacoustic data (to determine the extent of shore platforms), the modelling of higher-order polynomial functions describing their extent, followed by the integral calculus of the indicated functions within the open-source Desmos environment. The retreat dynamics for individual landslides (S1) was an order of magnitude higher (m/yr) than the average for the whole cliff section (0.17 ± 0.008 m/yr), which correlates well with medium- and long-term development tendencies and recession dynamics, revealed by the numerical modelling method, since approximately 8 ka b2k, years before 2000 CE (at S1 = 0.17 ± 0.020 m/yr, at S2 = 0.11 ± 0.005 m/yr). While the approach described in this paper can reveal, project, and simulate the dynamics of past and future trends within other cliffed coasts shaped in tideless conditions, it also proves stable moraine erosional responses to sea-level rise since the Mid-Holocene.
This paper tests the pollution emissions and institutional quality nexus in Africa. Specifically, we analyze the effect of the political regime and the quality of political governance on CO2 emissions. To control for endogeneity, we apply the system generalized method of moments on a dynamic panel of African countries over the period 1996–2020. The key finding suggests that better institutions have a negative and significant effect on pollution in Africa. The findings also validate the environmental Kuznets curve hypothesis. Moreover, the results support the pollution haven hypothesis. Finally, if digitalization significantly curbs pollution, then industrialization, natural resources, as well as the intensive use of energy, are considered as positive predictors. All the sensitivity and robustness tests globally validate the strength of the negative association between the good quality of institutions and the level of polluting emissions in Africa. The results call for some policy recommendations in environmental regulation for African economies.
We consider the problem of obtaining effective representations for the solutions of linear, vector-valued stochastic differential equations (SDEs) driven by non-Gaussian pure-jump Lévy processes, and we show how such representations lead to efficient simulation methods. The processes considered constitute a broad class of models that find application across the physical and biological sciences, mathematics, finance, and engineering. Motivated by important relevant problems in statistical inference, we derive new, generalised shot-noise simulation methods whenever a normal variance-mean (NVM) mixture representation exists for the driving Lévy process, including the generalised hyperbolic, normal-gamma, and normal tempered stable cases. Simple, explicit conditions are identified for the convergence of the residual of a truncated shot-noise representation to a Brownian motion in the case of the pure Lévy process, and to a Brownian-driven SDE in the case of the Lévy-driven SDE. These results provide Gaussian approximations to the small jumps of the process under the NVM representation. The resulting representations are of particular importance in state inference and parameter estimation for Lévy-driven SDE models, since the resulting conditionally Gaussian structures can be readily incorporated into latent variable inference methods such as Markov chain Monte Carlo, expectation-maximisation, and sequential Monte Carlo.
This paper considers the family of invariant measures of Markovian mean-field interacting particle systems on a countably infinite state space and studies its large deviation asymptotics. The Freidlin–Wentzell quasipotential is the usual candidate rate function for the sequence of invariant measures indexed by the number of particles. The paper provides two counterexamples where the quasipotential is not the rate function. The quasipotential arises from finite-horizon considerations. However, there are certain barriers that cannot be surmounted easily in any finite time horizon, but these barriers can be crossed in the stationary regime. Consequently, the quasipotential is infinite at some points where the rate function is finite. After highlighting this phenomenon, the paper studies some sufficient conditions on a class of interacting particle systems under which one can continue to assert that the Freidlin–Wentzell quasipotential is indeed the rate function.
It is generally believed that the velocity and passive scalar fields share many similarities and differences in wall-bounded turbulence. In the present study, we conduct a series of direct numerical simulations of compressible channel flows with passive scalars and employ the two-dimensional spectral linear stochastic estimation and the correlation function as diagnostic tools to shed light on these aspects. Particular attention is paid to the relevant multiphysics couplings in the spectral domain, i.e. the velocity–temperature ($u-T$), scalar–temperature ($g-T$) and velocity–scalar ($u-g$) couplings. These couplings are found to be utterly different at a given wall-normal position in the logarithmic and outer regions. Specifically, in the logarithmic region, the $u-T$ and $u-g$ couplings are tight at the scales that correspond to the attached eddies and the very large-scale motions (VLSMs), whereas the $g-T$ coupling is robust in the whole spectral domain. In the outer region, $u-T$ and $u-g$ couplings are only active at the scales corresponding to the VLSMs, whereas the $g-T$ coupling is diminished but still strong at all scales. Further analysis indicates that although the temperature field in the vast majority of zones in a channel can be roughly treated as a passive scalar, its physical properties gradually deviate from those of a pure passive scalar as the wall-normal height increases due to the enhancement of the acoustic mode. Furthermore, the deep involvement of the pressure field in the self-sustaining process of energy-containing motions also drives the streamwise velocity fluctuation away from a passive scalar. The current work is an extension of our previous study (Cheng & Fu, J. Fluid Mech., vol. 964, 2023, A15), and further uncovers the details of the multiphysics couplings in compressible wall turbulence.
Following the first-ever rule of law conditionality procedure in September 2022, a resolution was adopted by the European Parliament which declared that Hungary could no longer be considered a full democracy, as it had turned into a ‘hybrid regime of electoral autocracy’. Against this background, this article explains the business and human rights (BHR) gap in Hungary and presents its consequences for the Ukrainian refugee crisis. We first provide a general overview of the role of business in the development and consolidation of the Orbán regime over the past 13 years, highlighting how businesses are both agents and victims of legal and political developments. The paper distinguishes four types of ‘business’: multinational and foreign companies that are direct beneficiaries of the regime; local companies that are direct beneficiaries of the regime; multinational companies that are targets of restrictive and repressive populist rhetoric and economic policies; and the ‘rest’, the remainder that try to avoid becoming targets of oligarchic takeovers. The article also documents how the state and other stakeholders are failing to meet their commitments under the United Nations Guiding Principles on Business and Human Rights (UNGPs). The next part of the article assesses how companies are responding to the refugee crisis caused by the war in Ukraine, Hungary’s neighbour. If the government does not adopt Pillar I and Pillar III of the UNGPs, what room for manoeuvre do companies have? The focus here is on how companies, domestic and foreign, multinational enterprises (MNEs) and small and medium enterprises (SMEs), engage in humanitarian (and human rights) crisis management.
During the first decades of the twentieth century when the Indian freedom struggle movement gained momentum, M. K. Gandhi often evoked Mirabai—the sixteenth-century bhakti poet-saint—in his public speeches and voluminous letters. This article demonstrates the degree to which Gandhi's maneuver fundamentally altered Mirabai's image as a national and cultural symbol, and how it prompted the mobilization of women in the larger nationalist movement. Through the process of appropriation, Mirabai's image evolved in the Indian cultural realm from a woman charged with promiscuity into an ideal “chaste” woman. Gandhi's intervention further initiated a moral renaissance parallel to the nationalist current where women transgressed the thresholds of traditional domesticity and became active agents of non-violent resistance—Hindu/spiritual in essence—inspired by Mirabai's suffering and compositions. Gandhi's Mira emerged as a literary-cultural hybrid that circulated in public spheres, as Mirabai became a public icon and a vehicle for women's emancipation alongside national liberation.
The interaction between the flow in a channel with an obstruction on the bottom and an elastic sheet representing the ice covering the liquid is considered for the case of steady flow. The mathematical model based on the velocity potential theory and the theory of thin elastic shells fully accounts for the nonlinear boundary conditions at the elastic sheet/liquid interface and on the bottom of the channel. The integral hodograph method is employed to derive the complex velocity potential of the flow, which contains the velocity magnitude at the interface in explicit form. This allows one to formulate the coupled ice/liquid interaction problem and reduce it to a system of nonlinear equations in the unknown magnitude of the velocity at the interface. Case studies are carried out for a semi-circular obstruction on the bottom of the channel. Three flow regimes are studied: a subcritical regime, for which the interface deflection decays upstream and downstream; an ice supercritical and channel subcritical regime, for which two waves of different lengths may exist; and a channel supercritical regime, for which the elastic wave is found to extend downstream to infinity. All these regimes are in full agreement with the dispersion equation. The obtained results demonstrate a strongly nonlinear interaction between the elastic and the gravity wave near the first critical Froude number where their lengths approach each other. The interface shape, the bending moment and the pressure along the interface are presented for wide ranges of the Froude number and the obstruction height.
The original Specker–Blatter theorem (1983) was formulated for classes of structures $\mathcal {C}$ of one or several binary relations definable in Monadic Second Order Logic MSOL. It states that the number of such structures on the set $[n]$ is modularly C-finite (MC-finite). In previous work we extended this to structures definable in CMSOL, MSOL extended with modular counting quantifiers. The first author also showed that the Specker–Blatter theorem does not hold for one quaternary relation (2003).
If the vocabulary allows a constant symbol c, there are n possible interpretations on $[n]$ for c. We say that a constant c is hard-wired if c is always interpreted by the same element $j \in [n]$. In this paper we show:
(i) The Specker–Blatter theorem also holds for CMSOL when hard-wired constants are allowed. The proof method of Specker and Blatter does not work in this case.
(ii) The Specker–Blatter theorem does not hold already for $\mathcal {C}$ with one ternary relation definable in First Order Logic FOL. This was left open since 1983.
Using hard-wired constants allows us to show MC-finiteness of counting functions of various restricted partition functions which were not known to be MC-finite till now. Among them we have the restricted Bell numbers $B_{r,A}$, restricted Stirling numbers of the second kind $S_{r,A}$ or restricted Lah-numbers $L_{r,A}$. Here r is a non-negative integer and A is an ultimately periodic set of non-negative integers.
The relation between time and gender has been extensively discussed in feminist theory, from Simone de Beauvoir to recent studies of queer temporality and crip time. In this article, I explore gender as “lived time” in relation to a pressing feminist issue: social recognition of the chronic illness endometriosis (endo). Based on my interviews with individuals diagnosed with endo, I argue that lived time can be studied by approaching becoming as a dynamic process or flow of recognition, creating certain temporal patterns in the lifeworld. I propose the concept of “endo time” as a phenomenological conception of the lived time of endo. I identify three temporal patterns that characterize endo time: waiting time (I), cyclical or chronic time (II), and sedimented time (III). The analysis contributes to feminist philosophy by detailing how gender appears as a specific orchestration of time. Because of its connection to feminized pain and menstrual flow on the one hand and social recognition on the other, endo presents an illuminating case for exploring the relation between gender, recognition, and lived time.
Cet article propose une réflexion sur les initiatives politiques déployées ces dernières années un peu partout en Occident afin de rendre les forces armées plus « représentatives ». S'il est difficile de contester la légitimité démocratique de ces initiatives, celles-ci risquent néanmoins de porter atteinte à l'autonomie professionnelle des officiers au sein des forces armées, conformément à ce que nous appelons le « compromis huntingtonien », soit le modèle de relations civilo-militaires qui domine encore aujourd'hui en Occident. En effet, en intervenant directement dans les « affaires internes » des forces armées, le pouvoir civil se trouve ainsi à empiéter sur les pouvoirs et le champ des responsabilités professionnelles exercées par les officiers sur les forces armées. Pour pallier ce risque, nous proposons un élargissement du « rôle politique » de l'officier, à l'intérieur même du cadre fixé par le compromis huntingonien. Cela devrait se traduire par deux axes complémentaires d'action pour l'officier aujourd'hui négligés : d'une part, défendre la place singulière des forces armées dans la société et, d'autre part, agir en tant qu'agent de changement culturel au sein des forces armées.
In this paper, we prove that the lower triangular matrix category $\Lambda =\left [ \begin{smallmatrix} \mathcal{T}&0\\ M&\mathcal{U} \end{smallmatrix} \right ]$, where $\mathcal{T}$ and $\mathcal{U}$ are $\textrm{Hom}$-finite, Krull–Schmidt $K$-quasi-hereditary categories and $M$ is an $\mathcal{U}\otimes _K \mathcal{T}^{op}$-module that satisfies suitable conditions, is quasi-hereditary. This result generalizes the work of B. Zhu in his study on triangular matrix algebras over quasi-hereditary algebras. Moreover, we obtain a characterization of the category of the $_\Lambda \Delta$-filtered $\Lambda$-modules.
Does political diversity affect the prevalence of selfless behavior across a society? According to a recurrent finding from the study of social capital, ethnic diversity reduces prosocial behavior. We ask whether the same applies to partisan identity, by turning to a frequently used proxy for social capital: blood donations. The question is especially timely: the United States is currently experiencing its worst blood shortage in over a decade. Using survey results covering over 275,000 individuals in the US from 2010 to 2020, and a preregistered survey of an additional 3,500 respondents, we show that not all measures of social diversity have analogous effects on prosocial behavior. We find mixed evidence for a region’s share of immigrants being linked to lower blood donation by US citizens, and no negative effect for racial diversity. By contrast, political diversity appears to be highly significant. Specifically, individuals are less likely to donate blood when their partisan position is farther from the mean political identity in their state or commuting zone, and when they perceive themselves to be political outliers in their community. Affective polarization is known to be a tax on social interaction with out-partisans; as we show, depending on an area’s partisan makeup, it can also be a tax on prosocial behavior writ large.
We give three counterexamples to the folklore claim that in an arbitrary theory, if a complete type p over a set B does not divide over $C\subseteq B$, then no extension of p to a complete type over $\operatorname {acl}(B)$ divides over C. Two of our examples are also the first known theories where all sets are extension bases for nonforking, but forking and dividing differ for complete types (answering a question of Adler). One example is an $\mathrm {NSOP}_1$ theory with a complete type that forks, but does not divide, over a model (answering a question of d’Elbée). Moreover, dividing independence fails to imply M-independence in this example (which refutes another folklore claim). In addition to these counterexamples, we summarize various related properties of dividing that are still true. We also address consequences for previous literature, including an earlier unpublished result about forking and dividing in free amalgamation theories, and some claims about dividing in the theory of generic $K_{m,n}$-free incidence structures.
