We give a construction of the free dcpo-cone over any dcpo. There are two steps for getting this result. Firstly, we extend the notion of power domain to directed spaces which are equivalent to $T_0$ monotone-determined spaces introduced by Erné, and we construct the probabilistic powerspace of the monotone determined space, which is defined as a free monotone determined cone. Secondly, we take D-completion of the free monotone determined cone over the dcpo with its Scott topology. In addition, we show that generally the valuation power domain of any dcpo is not the free dcpo-cone.
A game that characterizes equivalence of structures with respect to all first-order sentences containing a given number of quantifiers was introduced by Immerman in 1981. We define three other games and prove that they are all equivalent to the Immerman game, and hence also give a characterization for the number of quantifiers needed for separating structures. In the Immerman game, Duplicator has a canonical optimal strategy, and hence Duplicator can be completely removed from the game by replacing her moves with default moves given by this optimal strategy. On the other hand, in the last two of our games there is no such optimal strategy for Duplicator. Thus, the Immerman game can be regarded as a one-player game, but two of our games are genuine two-player games.
Can and should judges refer to the natural law? I address these questions from the point of view of James Wilson, paying specific attention to a question the scholarship does not address: Why does Wilson believe judges can (and must), in certain instances, refer to natural law? I develop a new taxonomy of Wilson's conception of judgment that answers this question. Wilson's definition of judgment as including the moral sense and reason, and his division of reasoning into demonstrative, moral, and legal reasoning, indicate why he countenances judicial recourse to natural law in certain cases yet remains committed to popular sovereignty and judicial restraint. Wilson describes “judgments of nature” as intuitive judgments based on self-evident truths and articulates how judges might be called upon to make certain judgments based on a manifest repugnancy to the natural law. His judicial decisions confirm this commitment to natural law and judicial restraint.
In this paper, we expand on existing studies of Canadian Inuit art in the international arena by examining ways in which this new art served domestic purposes, focusing primarily on the 1950s and 1960s. The Canadian government developed and promoted Inuit art as part of its project to transform Inuit from semi-independent hunters into modern Canadian citizens. In this effort, Canada took up and assimilated Inuit art as a genuine Canadian cultural product, presenting it as diplomatic gifts and for other forms of international cultural diplomacy. Previous studies of Canadian Inuit art from that era have noted the ways that the promotion of Canadian Inuit art supported the young nation’s claims to a deep history, while simultaneously marking the country’s distinction from both the United States and the United Kingdom. In the context of the Cold War, the promotion of Canadian Inuit art also asserted Canada as an Arctic power. Labelled as “primitive modernist” fine art, Inuit sculpture and prints provided a stark contrast to the contemporaneous socialist realist art of the Soviet Union and its allies. We argue that the success of the Inuit art program sustained a belief among government officials that their programme to remake Inuit lives and livelihoods would succeed. Inuit art likely deflected attention from the many things that were going wrong with that northern modernisation project.
Throughout the history of television, American audiences have participated in a tradition of programs that follow a consistent structure: Amateur musicians and entertainers are offered an opportunity to display their talent on stage, competing for audience votes to win first prize and a chance at stardom. This article contributes to a growing literature on the significance of televised talent shows, demonstrating how their remarkable longevity and representational power stems from their configuration as a “format,” the set of guidelines that structure and constrain the content of each broadcast—an aesthetic process grounded in exclusion. Through their formatting, I argue, these programs reify the notion of “talent” at the heart of talent shows, transforming a multidimensional and context-contingent assemblage of musical abilities into a seemingly stable object able to be recognized, rated, and ranked. Musical auditions offer a microcosm of formatting's role as a means of training audiences’ attention. They normalize the practice of eliminating whatever (or whomever) is deemed unworthy—on these programs and in the wider world. Through analyzing examples from Ted Mack and the Original Amateur Hour (1948), The Gong Show (1978), and The Voice (2017), the article demonstrates how beneath the widely discussed content of contestant demographics, judge commentary, or audience voting results, the talent show format serves to obscure the contradictions upon which meritocracy's cruel optimism rests.
We provide explicit bounds for the Riemann zeta-function on the line $\mathrm {Re}\,{s}=1$, assuming that the Riemann hypothesis holds up to height T. In particular, we improve some bounds in finite regions for the logarithmic derivative and the reciprocal of the Riemann zeta-function.
Les pays ayant une structure politique fédérale sont souvent confrontés aux revendications de leurs États membres pour obtenir plus d'autonomie politique. Pour répondre à ces revendications, les théoriciens du fédéralisme multinational ont proposé de reconnaître un droit à l'autodétermination interne qu'ils ont pris soin d'encadrer de diverses manières. Bien qu'intéressante, cette proposition pourrait toutefois s'avérer insuffisante pour répondre aux inégalités entre les peuples au sein d'une même fédération. C'est la thèse que nous défendrons dans le présent article. Nous montrerons que le concept d'autodétermination interne défendu par Kymlicka reste indéterminé et ouvre la porte à des interprétations plus exigeantes.
This article explores the responses of the South African competition authorities to the impact of the COVID-19 pandemic on the socio-economic rights of consumers in relation to the price gouging of essential and medical supplies. After discussing the constitutional and legislative context of socio-economic rights and excessive pricing, it examines the first case in which the competition authorities were called upon to decide on the excessive pricing of medical supplies during COVID-19. The article finds that, while the competition authorities were swift to interpret the Competition Act widely and act against suppliers charging excessive prices, there remains a gap in South Africa's legislative framework as there is no specific legislation regulating price gouging during states of pandemic or disaster. The article identifies the need for legislative development and concludes by offering recommendations for addressing future incidents of price gouging.
Goodman defends that most maligned aspect of the rhetorical tradition: eloquence. Surely, one would think that eloquence, by its very nature, speaks for itself and quite effectively so, with all the pleasing and persuasive effects of a grand style. Perhaps popular audiences are easily carried along by decorous speech, but Goodman addresses his defense to theorists of politics who tend to greet obvious rhetorical flourish with a deep suspicion of manipulation and deception, or at least of frivolity. On this view, the best thing that can be said about eloquence in its classical form is that it poses no serious threat since the modern advent of mass society and large-scale democracy marks its demise. Goodman forces readers to reconsider the story of the rhetorical tradition's elitist, manipulative, and obsolete character through an engaging, nuanced, and unexpected retelling of Ciceronean eloquence as a tradition that spans the ancient and modern world, one that survives and responds to the challenges of democratic judgment in large polities. Goodman's compelling and insightful book poses an important challenge to theorists of democracy, both contemporary and historical, to take eloquence seriously as an invitation to democratic judgment.
Given a graph G, the minimum Connected-k-Subgraph Cover problem (MinCkSC) is to find a minimum vertex subset C of G such that every connected subgraph of G on k vertices has at least one vertex in C. If furthermore the subgraph of G induced by C is connected, then the problem is denoted as MinCkSC$_{con}$. In this paper, we first present a PTAS for MinCkSC on an H-minor-free graph, where H is a graph with a constant number of vertices. Then, we design an $O((\omega+1)(2(k-1)(\omega+2))^{3\omega+3})|V|$-time FPT algorithm for MinCkSC$_{con}$ on a graph with treewidth $\omega$, based on which we further design an $O(2^{O(\sqrt{t}\log t)}|V|^{O(1)})$ time subexponential FPT algorithm for MinCkSC$_{con}$ on an H-minor-free graph, where t is an upper bound of solution size.
Past studies have demonstrated that Ruppia cirrhosa (Ruppia), which typically grows in brackish water, is far too unreliable to serve as the chronological basis for radiocarbon dating because of the hard water effect (HWE). Despite this unreliability, Ruppia seeds have been used to date footprints along the margins of paleo-Lake Otero in southern New Mexico to around 23,000–21,000 cal yr BP. In this study, we employ a modern analog approach using δ13C values and radiocarbon dates from modern Ruppia plants growing in Salt Creek to calculate a maximum limiting age range for the footprints. Those plant samples with higher δ13C values produced greater age discrepancies. This simple relationship can be used to correct for the HWE and demonstrates that the human footprints purported to have been made during the local last glacial maximum could be at least ~7500 yr younger.
On November 15, 2019, following almost a month of massive daily demonstrations across Chile, most political parties agreed to initiate an unprecedented constituent process. This process introduced institutional innovations for the Constitutional Convention elections, including gender parity, reserving 17 seats for indigenous individuals, and allowing nonparty candidates to run as independent candidates (Heiss 2021; Suárez-Cao 2021).
There are little reported data on the perspectives of fathers caring for children with chronic conditions. Although survival of children with advanced heart disease has improved, long-term morbidity remains high. This study describes the experience and prognostic awareness of fathers of hospitalised children with advanced heart disease.
Methods:
Cross-sectional survey study of parents caring for children hospitalised with advanced heart disease admitted for ≥ 7 days over a one-year period. One parent per patient completed surveys, resulting in 27 father surveys. Data were analysed using descriptive methods.
Results:
Nearly all (96%) of the fathers reported understanding their child’s prognosis “extremely well” or “well,” and 59% felt they were “very prepared” for their child’s medical problems. However, 58% of fathers wanted to know more about prognosis, and 22% thought their child’s team knew something about prognosis that they did not. Forty-one per cent of fathers did not think that their child would have lifelong limitations, and 32% anticipated normal life expectancies. All 13 fathers who had a clinical discussion of what would happen if their child got sicker found this conversation helpful. Nearly half (43%) of the fathers receiving new prognostic information or changes to treatment course found it “somewhat” or “a little” confusing.
Conclusions:
Fathers report excellent understanding of their child’s illness and a positive experience around expressing their hopes and fears. Despite this, there remain many opportunities to improve communication, prognostic awareness, and participation in informed decision-making of fathers of children hospitalised with advanced heart disease.
In his encyclopedic masterwork Li livres dou Tresor (The Books of Treasure), the mid-thirteenth-century Florentine civil servant and rhetorician Brunetto Latini proclaimed “the very wise Marcus Tullius Cicero” to be “the finest orator in the world and the master of rhetoric.”1 How might this remark by a medieval professional civic administrator (even one with pronounced Ciceronian proclivities) pertain to Goodman's book? I take as my inspiration for the ensuing comments Latini's phrase in Tresor—“The very wise Marcus Tullius Cicero”—in relation to the final word of Goodman's subtitle: “Conditions.” As I began to peruse Words on Fire, I expected to encounter discussion of “wisdom” and of related ideas such as “reason,” “natural law,” and “justice” rather often. After all, these factors constitute indispensable features of Cicero's political theory. I was thus greatly surprised to discover that Goodman mentions them only belatedly and briefly (65–66).
Investigating the developments in the ever-growing field of disaster medicine and revealing the scientific trends will make an important contribution to researchers in related fields. This study aims to identify the contributions of emergency medicine physicians (EMPs) and trends in disaster medicine publications.
Methods:
The expressions “disaster medicine” or “disaster*” and “medicine*” were searched in the Web of Science (WoS) database. Research and review papers produced by EMPs from 2001 through 2021 were included in the study. Basic descriptive information was assessed such as the number of publications, authors, citations, most active authors, institutions, countries, and journals. In addition, conceptual, intellectual, and social structures were analyzed.
Results:
The study included a total of 346 papers written by 1,500 authors. The mean citation rate per publication was 13.2. Prehospital and Disaster Medicine, Disaster Medicine and Public Health Preparedness, and Academic Emergency Medicine were the journals with the highest number of publications and the highest number of citations. The most common keywords used by the authors were “disaster medicine,” “emergency medicine,” and “disaster/disasters.” According to the distribution of the corresponding authors by country, the United States (n = 175), Japan (n = 23), Italy (n = 20), Australia (n = 17), and Canada (n = 17) had the highest number of publications. The institutions that produced the most publications were John Hopkins University (n = 37), Brigham and Women’s Hospital (n = 27), George Washington University (n = 25), University Piemonte Orientale (n = 24), and Brown University (n = 22).
Conclusion:
Increasingly, EMPs have contributed to disaster medicine publications over the years. This study can be used as a guide for EMPs and other researchers who want to contribute to the disaster medicine literature.
In recent years, many emerging actors (e.g., new social movements and parties) associate democratic problems with representative institutions. Accordingly, as a solution, they propose to introduce direct citizen participation in constitution and law making. However, three fallacies undermine the potential benefits of citizen participation: (1) attributing a moral and/or epistemic superiority to “the people”; (2) assuming that superiority, expecting to replace representation with direct participation; and (3) supposing that the legitimacy deficit will be resolved automatically by introducing inclusive direct participation. This article argues against these three ideas by providing a framework to understand participatory constitution making and briefly examining the cases of Chile and Iceland.
Failure of the patent ductus arteriosus to close is common among extremely low birth weight neonates and has been associated with increased morbidities. The objective of this study was to compare outcomes between early and late surgical ligation in extremely low birth weight patients.
Methods:
This was a single-centre retrospective cohort study of infants who required surgical closure of patent ductus arteriosus between January 2017 and August 2022.
Results:
A total of 43 neonates were identified with birth weight less than 1 kg that underwent surgical patent ductus arteriosus ligation. Compared to the late ligation group, the early ligation group experienced fewer total days of mechanical ventilation (43.9 days vs. 97.2 days, p < 0.05) and a shorter length of hospital stay (114.2 days vs. 169.0 days, p < 0.05).
Conclusion:
Early surgical ligation of haemodynamically significant patent ductus arteriosus in extremely low birth weight neonates may improve hospital morbidity, including improved ventilatory outcomes and a shorter length of stay.
