After outlining sceptical theism (ST) and the fine-tuning argument (FTA), I demonstrate how arguments for the former undercut the latter. I then consider and reject three recent proposals for ameliorating the conflict: positive ST, considerations about normative superiors, and appeal to theistic metaethics. I contend, however, that Kirk Durston’s complexity argument for ST does not undercut the FTA but in fact supports it. In defending that thesis, I respond to Climenhaga’s contention that ST undermines all warrant for theistic belief, the FTA included.
This paper investigates the increasing, but complex, support for reparations among Democratic elected officials—highlighting their tendency to endorse the concept while deferring discussion of policy details. This strategic ambiguity is common in policy discourse and can be embedded within policy design, such as legislative proposals to create commissions tasked with studying and recommending future actions on reparations. The effectiveness of these reparations commissions is uncertain. They could represent productive steps toward genuine reparations or simply serve to alleviate political pressure without any substantial policy changes. We explore these potential outcomes in three inter-related analyses: a compilation and comparison of all bills mentioning slavery reparations introduced at the federal and state level, the first nationally representative public opinion poll asking about support for reparations commissions, and a content analysis of legislative bill texts establishing reparations commissions. Our findings suggest that while reparations commissions offer an effective way for Democratic policymakers to manage conflicting constituency pressures in the short term, their potential to propel forward, rather than stall, the reparations debate hinges on their design and execution.
Developed in this study is a theoretical description of squeeze-film lubrication systems that involve the flexural oscillation of a thin plate near a parallel wall. Such systems were discovered in recent experiments to produce load-bearing attractive forces that are a thousandfold stronger than those generated by rigid oscillators, which typically favour repulsion. Analyses of squeeze-film gas flow driven by a presumed plate deformation reproduce the observed magnification of attractive load capacity, but exhibit serious discrepancies with crucial aspects of the experimental measurements – most importantly, the precise distribution of air pressure along the film. The discrepancies are resolved in this study by accounting for the presence of two-way-coupled fluid–structure interactions whereby the undulations of the plate, modelled here with use of the classical Kirchhoff–Love equation, are affected non-negligibly by the evolving pressure, described by a modified Reynolds lubrication equation that accounts for compressibility. The resulting problem of elastohydrodynamic lubrication is solved with use of perturbation methods that exploit the limit of small oscillation amplitudes. The analysis ultimately provides an explicit expression specifying the attractive load capacity of a squeeze-film system as a function of relevant operating parameters – including, in particular, the amplitude and frequency of the localized excitation force exerted on the plate. The rudimentary theory derived here may be readily generalized to guide the analysis and development of a wide variety of emerging engineering systems that exploit the vibration-induced squeeze-film effect – such as wall-climbing soft robots and contactless grippers.
Although many positive social changes have been achieved over the past 30 years, members of LGBT, Sistergirl and Brotherboy communities continue to encounter negative experiences with health and ageing service provision. In this article, 232 responses from a survey exploring ageing and care concerns and preferences among LGBT, Sistergirl and Brotherboy communities in Australia were analysed using chi square analysis. The largest proportion of participants were aged 55–64 years (26.4%, n = 61), with the majority residing in metropolitan regions (67.7%, n = 154). The three most frequently selected gender identities were cisgender woman (40.1%, n = 93), cisgender man (39.7%, n = 92) and non-binary (11.6%, n = 28). The three most frequently selected sexual orientations were gay (39.2%, n = 91), lesbian (32.0%, n = 77) and queer (17.7%, n = 41). While many concerns demonstrated no age-related differences, concerns regarding physical differences, respect and inclusion, finances and standard of care reflected higher levels of concern among younger participants compared with older participants. Preferences for receiving information reflected a desire for LGBT, Sistergirl and Brotherboy communities-specific resources for options for support from participants approaching retirement, that is, aged 55–64 (x2 (5, n = 178) = 11.08, p = 0.050); less desire for information provided through public health service services among participants aged 65+ (x2 (5, n = 178) = 15.58, p = 0.008); and variation in preferences regarding supports provided by LGBT, Sistergirl and Brotherboy communities. Results suggest that different generations of LGBT, Sistergirl and Brotherboy members may prefer to receive services and information in different ways. Further research is needed to understand how concerns, expectations and preferences are influenced across generations.
By employing the external Kasparov product, in [18], Hawkins, Skalski, White, and Zacharias constructed spectral triples on crossed product C$^\ast $-algebras by equicontinuous actions of discrete groups. They further raised the question for whether their construction turns the respective crossed product into a compact quantum metric space in the sense of Rieffel. By introducing the concept of groups separated with respect to a given length function, we give an affirmative answer in the case of virtually Abelian groups equipped with certain orbit metric length functions. We further complement our results with a discussion of natural examples such as generalized Bunce-Deddens algebras and higher-dimensional noncommutative tori.
The maximum temperature that a geotechnical bentonite barrier in a deep geological repository for radioactive waste can withstand while maintaining its integrity and meeting safety requirements is still an open question. Therefore, an international consortium set up an in situ heater test (HotBENT experiment) at the Grimsel Test Site (GTS) in Switzerland at relevant scales and gradients with temperatures ranging from 175°C to 200°C at the heater/canister surface. After dismantling (5 and 20 years, respectively), the identification of bentonite alteration processes of (clay) minerals has to be based on the comparison of data with reference values determined before the heating started. The experiment was set up using ~150 tons of two different clays (Wyoming and BCV from the Czech Republic) provided in different batches. The bentonites were used both as compacted bentonite blocks and as granular bentonite material (GBM). The determination of representative mineralogical and geochemical bentonite reference values must be based on a significant number of samples taken from all parts of the experiment, which is presented here. Most of the compositional variability was close to the accuracy of the methods used. However, chemical, mineralogical and exchangeable cation analyses showed that different raw materials were used to produce the BCV top blocks. The Wyoming bentonite used is similar to MX80 bentonite in that it is dominated by Na-rich smectite, but the HotBENT material contains slightly more feldspar and zeolite and slightly less smectite. Overall, 55 samples were analysed from different parts of the experiment, providing a statistical basis for post-excavation investigations.
Extubation failure after neonatal cardiac surgery is associated with increased intensive care unit length of stay, morbidity, and mortality. We performed a quality improvement project to create and implement a peri-extubation bundle, including extubation readiness testing, spontaneous breathing trial, and high-risk criteria identification, using best practices at high-performing centers to decrease neonatal and infant extubation failure by 20% from a baseline of 15.7% to 12.6% over a 2-year period.
Methods
Utilising the transparency of the Pediatric Cardiac Critical Care Consortium database, five centres were identified as high performers, having better-than-expected neonatal extubation success rates with the balancing metric of as-expected or better-than-expected mechanical ventilation duration. Structured interviews were conducted with cardiac intensive care unit physician leadership at the identified centers to determine centre-specific extubation practices. Data from those interviews underwent qualitative content analysis which was used to develop a peri-extubation bundle. The bundle was implemented at a single-centre 17-bed cardiac intensive care unit. Extubation failure, defined as reintubation within 48 hours of extubation for anything other than a procedure, ventilator days and bundle compliance was tracked.
Results
There was a 41.4% decrease in extubation failure following bundle implementation (12 failures of 76 extubations pre-implantation; 6 failures of 65 extubations post-implementation). Bundle compliance was 95.4%. There was no difference in ventilator days (p = 0.079) between groups.
Conclusion
Implementation of a peri-extubation bundle created from best practices at high-performing centres reduced extubation failure by 41.4% in neonates and infants undergoing congenital heart surgery.
People living with dementia are often presumed to have no agency or capacity to act in the social world. They are often excluded from participating in research while research methodologies may not capture their embodied engagement with people and places. Yet, like everyone, people with dementia can express their agency in nuanced ways, for example, through emotions or embodied expression. In the conceptual framework discussed here, nuanced agency is conceived as consisting of non-deliberative elements (embodied, emotional, habituated, reflexive and intersubjective) and deliberative elements (choices or decisions and facilitative). Although people with dementia have been found to benefit from gardens with their sensory appeal, how they experience gardens is not well understood. This critical interpretive synthesis aims to explore how people with dementia experience nuanced forms of agency and citizenship in gardens. A conceptual framework of agency was developed to address the aim and support the analysis. Analysis of the 15 included studies highlighted the value of the conceptual framework in identifying a wider and more granular array of nuanced agency expressed in embodied form and through dialogue. This included expressions of intersubjective and facilitative agency that informed opportunities for people with dementia to experience relational citizenship socially in communal garden settings. These findings suggest an opportunity for researchers to explore the embodied agency of people living with dementia more comprehensively by applying theoretical concepts of agency. Further testing of the framework’s utility for guiding collection and analysis of primary data involving people with dementia in garden settings is recommended.
Although the energy stored in the lean tissue (LT) and adipose tissue (AT) is well known, the energy required to synthesise these tissues is obscure. Theoretically, the energy at the point at which ΔLT/Δ body weight (BW) reaches 100 % on a regression line, which indicates the relationship between ΔLT/ΔBW and the energy required for BW gain, is considered to be the energy expended to synthesise LT. Therefore, we investigated this relationship in rats. Rats were fed diets with different ratios of protein, fat and carbohydrates because their ΔLT/ΔBW values were expected to be different. Six-week-old male Sprague-Dawley rats had ad libitum access to normal (N, n 6), high-fat (HF, n 7) or high-protein (HP, n 8) diets for 4 weeks. The ΔLT/ΔBW was 0·77 in the N, 0·70 in the HF and 0·87 in the HP groups, respectively. The average energy required to gain BW was 8·8 kJ/g in the N group, 7·0 kJ/g in the HF group and 11·3 kJ/g in the HP group. We observed a positive correlation between ΔLT/ΔBW and energy required for BW gain. The regression line demonstrated that the energy expended to synthesise LT was 13·9 kJ/g and AT was −7·9 kJ/g. Therefore, combined with the energy stored in LT, the energy required to accumulate LT is approximately 19 kJ/g, whereas the energy to accumulate AT could not be elucidated.
The interface of science and law is a territory frequently occupied by policymakers. In facilitating this interface, epistemic communities have become significant influencers in policymaking, especially at the European Union (EU) level, as a result of its complex multilevel governance system. In this article we assess the quality and nature of interactions between epistemic communities and EU stakeholders on the Horizon-funded project ‘PrecisionTox’, by deploying the concept of epistemic communities developed by Haas, as well as the learning modes of epistemic communities as presented and adapted by Dunlop. The overarching goal of PrecisionTox is to advance the safety assessment of chemicals by establishing a new, cost-effective testing paradigm built from evolutionary theory, which entails reduction, replacement, and refinement of mammalian testing (the 3Rs). The study shows that EU-funded projects can provide an excellent platform for building epistemic communities and forging alliances with EU policymakers, especially when novel technologies may be unlocked and socialized. This study also explores the early interaction of policymakers with epistemic communities through different forms of learning to better understand the complexities surrounding these new technologies in order to set an agenda for policy interventions.
Excavation at the site of Bhagatrav yielded four layers of cultural deposits: the lowermost being the Sorath Harappan, the upper two are medieval, and layer three caps the Sorath Harappan layer. A horn-deity painted dish was found in a stratified context at the lowest level. The medieval deposit includes turquoise glazed and celadon wares, followed by an abundance of Monochrome Glazed Ware, which is otherwise known as Khambhat ware. The date of the Sorath Harappan layer of the site, the time and space of the horn-deity motif in the Harappan world, and the date of Khambhat ware have long been subjects of discussion. With the help of a series of absolute dating (radiocarbon and luminescence), this paper attempts to place the site, horn-deity motif, and the Khambhat ware in the cultural chronology of Gujarat.
Despite 30 years of research on economic inequality, the question of whether government ideology affects inequality remains unresolved. As rising inequality poses a major challenge to contemporary democracies, we ask: (when) do parties matter regarding inequality? Our systematic analysis finds that research is divided, with a tendency toward a pessimistic “no.” We decipher the factors that account for this split in theoretically predictable ways. We assess the roles played by the type of inequality, the time horizon, and the impact of policy channels. Bivariate and multivariate analyses of 393 TSCS-regression findings show how the type of inequality and a neglect of top incomes, a focus on short- rather than long-term effects, and the inclusion of policy channels that absorb the effects of parties strongly codetermine the results. Effects septuple depending on how these factors are combined. We draw three lessons that, when combined, foster a shift toward a more optimistic perspective on the latitude of politics.
Halloysite nanotubes (often abbreviated as HNTs) are technologically important owing to their unique structural and morphological features. Some of these features pre-exist in the naturally hydrated halloysite-(10 Å) parent clay mineral; others may develop during its dehydration towards halloysite-(7 Å). This is the first infrared spectroscopic study of the transition to halloysite-(7 Å), which, in combination with X-ray diffraction (XRD), aimed at advancing the structural description of the process. Three cylindrical and two polygonal halloysite-(10 Å) samples, in both their H- and D-forms, were measured by attenuated total reflectance (ATR), non-invasively and in situ, following step-wise equilibration from 70% relative humidity (RH) to <10% RH and back to 70% RH at ambient temperature. This approach allowed for recording the spectrum of the dehydrating (but not rehydrating) interlayer in the νO–D range, without interference from the inner νOH groups, or from the inner-surface νOH of anhydrous interlayers already present in the parent material. Besides the well-known ‘hole’ H2O species, a new type of H2O-decorated defect was detected at frequencies normally dominated by the inner νOH. This defect is linked to the microenvironment created by the detachment between layer packets and forming ‘crevices’ or ‘slits’ upon dehydration. In addition, the study of the νSi–O spectrum demonstrated that the dehydration of halloysite-(10 Å) leads to the parallel formation of localized, ordered, kaolinite-like domains co-existing with regions of accumulated disorder. The as-produced halloysite-(7 Å) had a non-ideal, open structure that resisted rehydration because the kaolinite-like domains do not rehydrate and act as permanent cross-links.
Nitrogen (N) is the most significant nutrient affecting crop growth and development for all types of crops, except legumes. The goal of this study was to optimize the N level for cotton grown in a semi-arid environment to enhance growth and development, determine N status, and increase seed cotton yield and biomass. Two independent field experiments each three years in duration were conducted, from 2007 to 2009 (Exp.-I) and 2018 to 2020 (Exp.-II). Experiments were laid out in a randomized complete block design with three replicates. The N treatments in Exp.-I were comprised of 0, 40, 80, 120, 160, 200 and 240 kg N/ha, while treatments in Exp.-II were comprised of 0, 70, 140, 210 and 280 kg N/ha. A wide range of data sets for cotton traits were recorded, including canopy height, leaf area index, the N status of the leaf and stem, seed cotton yield and time-series biomass data. The higher N rates 240 and 280 kg N/ha performed better for all these traits. However, the highest leaf N contents were recorded for 210 kg N/ha. Based on these results, it is suggested that under semi-arid conditions, slightly higher rates than optimum or recommended N rates could be applied as a strategy by cotton growers for a higher seed cotton yield. The findings of this study may also increase profitability in other cotton-growing areas that have similar weather conditions.
Democratic electoral systems characteristically take a Count-and-Report Approach to enfranchised citizens’ failure to turn out in political elections: The number of non-votes is counted and publicly reported, but non-votes are given no effect in the allocation of political offices. We morally assess this model in the context of legislative elections, and argue that it is pro tanto less desirable than another, counterfactual model which we label Proportional Non-Voter Sortition. This model provides that citizens’ non-votes shall be legislatively represented by legislators who are selected by lot from the non-voting part of the demos, and whose share of seats is proportional to the aggregate rate of non-voting in the legislative election. Our assessment of the two models specifically turns on the claim that a democracy’s legislature should reflect the full diversity of political views that exists within its demos (legislative inclusivity), and it offers two reasons to expect that Proportional Non-Voter Sortition serves legislative inclusivity better than the Count-and-Report Approach: 1) Proportional Non-Voter Sortition uniquely incentivizes political parties to integrate non-voter views into their political agendas and mobilisation activities; and 2) Proportional Non-Voter Sortition additionally enables the legislative articulation and advocacy of non-voter views by placing people in the legislature who are descriptively representative of non-voters. Through our discussion of different models for the post-electoral management of non-votes, we contribute to a body of normative democratic theorizing about citizens’ non-voting, but raise a distinct question that so far has remained unexplored.
This paper presents a novel compact self-quintuplexing antenna using a half-mode substrate-integrated waveguide cavity to implement multi-operation wireless services. The proposed antenna design incorporates five triangular protrusions of different dimensions, assembled with SIW to function as the radiating elements. Each radiator supports the one-eighth mode of the SIW cavity. The resonance frequencies of radiators are 3.63, 4.44, 5.23, 6.21, and 7.05 GHz. Each radiator operates at a distinct frequency due to the differing dimensions and is independently driven by 50 Ω microstrip lines. The measured reflection coefficients and isolation among any two ports are less than −10 dB and better than 23.6 dB, respectively. The measured gains at their respective resonant frequencies are 5.66, 4.84, 5.03, 7.08, and 6.59 dBi. The front-to-back ratio is better than 8.7 dB in each band. The difference of co-to-cross-polarization is greater than 19.3 dB.
Here we consider the discrete time dynamics described by a transformation $T:M \to M$, where T is either the action of shift $T=\sigma$ on the symbolic space $M=\{1,2, \ldots,d\}^{\mathbb{N}}$, or, T describes the action of a d to 1 expanding transformation $T:S^1 \to S^1$ of class $C^{1+\alpha}$ (for example $x \to T(x) =\mathrm{d} x $ (mod 1)), where $M=S^1$ is the unit circle. It is known that the infinite-dimensional manifold $\mathcal{N}$ of Hölder equilibrium probabilities is an analytical manifold and carries a natural Riemannian metric. Given a certain normalized Hölder potential A denote by $\mu_A \in \mathcal{N}$ the associated equilibrium probability. The set of tangent vectors X (functions $X: M \to \mathbb{R}$) to the manifold $\mathcal{N}$ at the point µA (a subspace of the Hilbert space $L^2(\mu_A)$) coincides with the kernel of the Ruelle operator for the normalized potential A. The Riemannian norm $|X|=|X|_A$ of the vector X, which is tangent to $\mathcal{N}$ at the point µA, is described via the asymptotic variance, that is, satisfies
Consider an orthonormal basis Xi, $i \in \mathbb{N}$, for the tangent space at µA. For any two orthonormal vectors X and Y on the basis, the curvature $K(X,Y)$ is
When the equilibrium probabilities µA is the set of invariant Markov probabilities on $\{0,1\}^{\mathbb{N}}\subset \mathcal{N}$, introducing an orthonormal basis $\hat{a}_y$, indexed by finite words y, we show explicit expressions for $K(\hat{a}_x,\hat{a}_z)$, which is a finite sum. These values can be positive or negative depending on A and the words x and z. Words $x,z$ with large length can eventually produce large negative curvature $K(\hat{a}_x,\hat{a}_z)$. If $x, z$ do not begin with the same letter, then $K(\hat{a}_x,\hat{a}_z)=0$.
