In 1653, the Congregation for the Propagation of the Faith created a secular mission for Scotland that initially struggled with finances and provision. Its Prefects argued that the Jesuits exacerbated these problems by failing to prepare students at the Scots College Rome intellectually for the mission. This article examines the resulting campaign for curricular reform that Scottish secular priests waged, one intended to improve missionaries’ pastoral skills and undermine the college's Jesuit administration. It ultimately demonstrates the significance of education to wider conflicts between Propaganda Fide and the Society of Jesus regarding missions and resources in the seventeenth century.
Why do racialised states subscribe to the racial international hierarchy? While the critical scholarship in International Relations (IR) has meaningfully unsettled the discipline’s silence on race, it remains bound to the white versus non-white binary, neglecting the transmission and persistence of racism in international politics outside that divide. This article proposes a Lacanian reading of race as constitutive of state subjectivity in the modern world order to address this gap. Focusing on Lacan’s notion of the ‘lack in the Other’, I suggest that non-West/non-white racism is a fantasy that racialised states construct upon encountering the void of ‘Whiteness’ as a master signifier. I argue that racialised states appropriate racism in response to the anxiety induced by the collapse of the Other’s authority. Using the case of Japan’s transition to a modern nation-state, I mobilise the framework to examine Japan’s flirtation with Western racial theories and subsequent attempts to depart from the white racial order by creating its own racial hierarchy.
Sleep deprivation, which is a decrease in duration and quality of sleep, is a common problem in today’s life. Epidemiological and interventional investigations have suggested a link between sleep deprivation and overweight/obesity. Sleep deprivation affects homeostatic and non-homoeostatic regulation of appetite, with the food reward system playing a dominant role. Factors such as sex and weight status affect this regulation; men and individuals with excess weight seem to be more sensitive to reward-driven and hedonistic regulation of food intake. Sleep deprivation may also affect weight through affecting physical activity and energy expenditure. In addition, sleep deprivation influences food selection and eating behaviours, which are mainly managed by the food reward system. Sleep-deprived individuals mostly crave for palatable energy-dense foods and have low desire for fruit and vegetables. Consumption of meals may not change but energy intake from snacks increases. The individuals have more desire for snacks with high sugar and saturated fat content. The relationship between sleep and the diet is mutual, implying that diet and eating behaviours also affect sleep duration and quality. Consuming healthy diets containing fruit and vegetables and food sources of protein and unsaturated fats and low quantities of saturated fat and sugar may be used as a diet strategy to improve sleep. Since the effects of sleep deficiency differ between animals and humans, only evidence from human subject studies has been included, controversies are discussed and the need for future investigations is highlighted.
Wave turbulence is the study of the long-time statistical behaviour of equations describing a set of weakly nonlinear interacting waves. Such a theory, which has a natural asymptotic closure, allows us to probe the nature of turbulence more deeply than the exact Kolmogorov laws by rigorously proving the direction of the cascade and the existence of an inertial range, predicting stationary spectra for conserved quantities, or evaluating the Kolmogorov constant. An emblematic example is given by fast rotating fluids for which a wave turbulence theory has been derived by Galtier (Phys. Rev. E, vol. 68, issue 1, 2003, p. 015301). This work involves non-trivial analytical developments for a problem that is anisotropic by nature. We propose here a new path for the derivation of the kinetic equation by using the anisotropy at the beginning of the analysis. We show that the helicity basis is not necessary to obtain the wave amplitude equation for the canonical variables that involve a combination of poloidal and toroidal fields. The multiple time scale method adapted to this anisotropic problem is then used to derive the kinetic equation that is the same as the original work when anisotropy is eventually taken into account. This result proves the commutativity between asymptotic closure and anisotropy. In addition, the multiple time scale method informs us that the kinetic equation can be derived without imposing restrictions on the probability distribution of the wave amplitude such as quasi-Gaussianity, or on the phase such as random phase approximation that naturally occurs dynamically.
We find firm cyclicality decreases by 40% after the inception of credit default swap (CDS) trading. The effect stems from CDS firms’ less aggressive asset growth in good times and is stronger for firms facing a more severe empty creditor problem. Important identification issues are addressed. The result cannot be explained with debt overhang, bank lending cyclicality, or the cyclicality of firms’ business fundamentals. It holds for the cyclicality of various corporate outcomes (inventories, cash, and employment). Importantly, CDS trading impedes unhealthy growth and enhances profitability and firm value. Our finding indicates an important positive real effect of financial innovation.
This paper is concerned with the relationship of $y$-smooth integers and de Bruijn's approximation $\Lambda (x,\,y)$. Under the Riemann hypothesis, Saias proved that the count of $y$-smooth integers up to $x$, $\Psi (x,\,y)$, is asymptotic to $\Lambda (x,\,y)$ when $y \ge (\log x)^{2+\varepsilon }$. We extend the range to $y \ge (\log x)^{3/2+\varepsilon }$ by introducing a correction factor that takes into account the contributions of zeta zeros and prime powers. We use this correction term to uncover a lower order term in the asymptotics of $\Psi (x,\,y)/\Lambda (x,\,y)$. The term relates to the error term in the prime number theorem, and implies that large positive (resp. negative) values of $\sum _{n \le y} \Lambda (n)-y$ lead to large positive (resp. negative) values of $\Psi (x,\,y)-\Lambda (x,\,y)$, and vice versa. Under the Linear Independence hypothesis, we show a Chebyshev's bias in $\Psi (x,\,y)-\Lambda (x,\,y)$.
Understanding the skin friction in an axisymmetric turbulent boundary layer (ATBL) flow is a key to designing and optimising the flow past axisymmetric bodies, for example, a rocket engine nozzle and a submarine hull. In this study, we propose a universal law of the skin-friction coefficient in an ATBL flow. The flow is steady and fully developed with a zero pressure gradient. The governing equation for the ATBL flow is derived by methodically applying the boundary layer approximation. Subsequently, the scaling law of the Reynolds shear stress, caused by turbulent eddies, at the surface tangential to the wall roughness summits is derived by incorporating the role of transverse curvature. The skin-friction coefficient in a smooth ATBL flow is found to depend on two parameters, namely, the Reynolds number based on the cylinder radius, Rea, and the ratio of boundary layer thickness to cylinder radius, δ/a. The analysis predicts a simple form of the skin-friction coefficient as ${C_f} = 4.56 \times {10^{ - 2}}{[R{e_a}\ln (1 + \delta /a)]^{ - 1/4}}$, which agrees satisfactorily with the available experimental data and the numerical simulations in all the axisymmetric flow regimes. The proposed law, in the limit of infinite radius, is consistent with the classical law of the skin-friction coefficient in a plane turbulent boundary layer flow as ${C_{f0}}\sim Re_\delta ^{ - 1/4}$, where Reδ is the Reynolds number based on the boundary layer thickness. This study reveals that, for δ/a < 1, the relative skin-friction coefficient, $({C_f} - {C_{f0}})/{C_{f0}}$, follows a linear law with δ$/$a.
Indigenous peoples continue to challenge Canadian colonial policies through nonroutine acts of resistance. Sustained scholarly attention on the frequency and characteristics of Indigenous resistance has dropped precipitously, with the time span of this scholarship typically ending by the early 2000s. Research on more recent acts of resistance is directed to small-n case studies. This research note examines Indigenous resistance in Canada between 2010 and 2020 as reported by news articles from the Canadian Broadcasting Corporation (CBC) to identify key characteristics of salient Indigenous resistance: What issue areas were the subject of resistance movements? Which Indigenous communities or groups contributed to acts of resistance? What strategies were employed? The research note's findings suggest that salient acts of resistance rarely result in immediate policy change from the state; instead, resistance has transformative potential to develop Indigenous governance that departs from settler-colonial state processes.
This experiment was conducted to investigate whether dietary chenodeoxycholic acid (CDCA) could attenuate high-fat (HF) diet-induced growth retardation, lipid accumulation and bile acid (BA) metabolism disorder in the liver of yellow catfish Pelteobagrus fulvidraco. Yellow catfish (initial weight: 4·40 (sem 0·08) g) were fed four diets: the control (105·8 g/kg lipid), HF diet (HF group, 159·6 g/kg lipid), the control supplemented with 0·9 g/kg CDCA (CDCA group) and HF diet supplemented with 0·9 g/kg CDCA (HF + CDCA group). CDCA supplemented in the HF diet significantly improved growth performance and feed utilisation of yellow catfish (P < 0·05). CDCA alleviated HF-induced increment of hepatic lipid and cholesterol contents by down-regulating the expressions of lipogenesis-related genes and proteins and up-regulating the expressions of lipololysis-related genes and proteins. Compared with the control group, CDCA group significantly reduced cholesterol level (P < 0·05). CDCA significantly inhibited BA biosynthesis and changed BA profile by activating farnesoid X receptor (P < 0·05). The contents of CDCA, taurochenodeoxycholic acid and glycochenodeoxycholic acid were significantly increased with the supplementation of CDCA (P < 0·05). HF-induced elevation of cholic acid content was significantly attenuated by the supplementation of CDCA (P < 0·05). Supplementation of CDCA in the control and HF groups could improve the liver antioxidant capacity. This study proved that CDCA could improve growth retardation, lipid accumulation and BA metabolism disorder induced by HF diet, which provided new insight into understanding the physiological functions of BA in fish.
Modal and non-modal linear stability analyses are employed to investigate the effect of internal and external heating on disturbance temporal growth for the Darcy–Bénard convection with throughflow. A matrix-forming approach is employed for both purposes, where the generalised eigenvalue problem is built using the generalised integral transform technique. Although the disturbance equations are not self-adjoint, the non-modal analysis indicates that there is no transient growth. Hence, any disturbance growth in time must be induced by modal mechanisms. An absolute instability analysis reveals that viscous dissipation has a destabilising effect and introduces new modes that are eventually destabilised by increasing the Péclet number. Beyond critical values of the Péclet number, where codimension-two absolutely unstable points exist, these modes become more unstable than the classical mode found in the absence of viscous dissipation, which is stabilised by an increasing Péclet number. This internal heating mechanism generated by viscous dissipation is so strong at high enough Péclet numbers that instability becomes possible through heating from above.
The problem of quantity is the problem of identifying what about the physical world explains why it can be so well represented with mathematical entities. I introduce “quantitative primitivism,” the dominant position in the literature, which offers only a partial solution to the problem of quantity. I argue that a reductive account of quantitativeness provides a full solution to the problem and describe two reductive accounts in the literature. I discuss some of the unique metaphysical consequences of reductive accounts of quantity, including a novel dissolution to the long-standing absolutist–comparativist debate.
At the turn of the twentieth century, Greek jurists insisted that the Ottoman Empire was legally pluralistic. While one jurist acknowledged the Sultan's ‘political purpose' in respecting the Greeks' privileges, another denied Muslims any agency free from Sharia. The alleged incommensurability between the Christian and Islamic law was their common agenda. Greek historians, on the other hand, saw the privileges as the Turks’ sign of goodwill, and emphasized the civilizational gap between the Catholic West and Ottoman East. Being a normative expression rather than a neutral description, legal pluralism functioned as a method of neglecting the Muslim quest for legal unity.
Defence Science and Technology Group (DSTG) is currently preparing for the launch of the Buccaneer Main Mission (BMM) satellite, the successor to the Buccaneer Risk Mitigation Mission (BRMM). BMM hosts a high-frequency (HF) antenna and receiver to contribute to the calibration of the Jindalee Operational Radar Network (JORN). Verification of the successful deployment and stability of the large HF antenna is critical to the success of the mission. A bespoke deployable optics payload has been developed by DSTG to fulfil the dual purpose of direct verification of the deployed state of the HF antenna and capturing images of the Earth through a rotatable, dual-surfaced mirror and a variable-focus liquid lens. The payload advances research at DSTG in several fields of space engineering, including deployable mechanisms, precision actuation devices, radiation-tolerant electronics, advanced metal polishing and optical metrology. This paper discusses the payload design, material selection, trade-offs considered for the deployable optics payload and preliminary test results.
Kolmogorov conditionalization is a strategy for updating credences based on propositions that have initial probability 0. I explore the connection between Kolmogorov conditionalization and Dutch books. Previous discussions of the connection rely crucially upon a factivity assumption: they assume that the agent updates credences based on true propositions. The factivity assumption discounts cases of misplaced certainty, i.e., cases where the agent invests credence 1 in a falsehood. Yet misplaced certainty arises routinely in scientific and philosophical applications of Bayesian decision theory. I prove a non-factive Dutch book theorem and converse Dutch book theorem for Kolmogorov conditionalization. The theorems do not rely upon the factivity assumption, so they establish that Kolmogorov conditionalization has unique pragmatic virtues that persist even in cases of misplaced certainty.
Vietnam’s initial response to Covid-19 was conspicuous for various reasons, including how its attempt at securitisation drew deeply from historical narratives, symbols, and traditions specific to the Vietnamese experience, as well as how the securitisation project was not simply top-down and state-driven but also featured ground-up participation where the public was mobilised to participate in and actively reiterate securitisation practices. This richly textured empirical case study of the workings of Vietnamese society and politics represents an invitation to explore key debates surrounding securitisation theory. Reflecting on the empirical material of the case, this paper builds on scholarship seeking to highlight the shortcomings of the Copenhagen School’s model of securitisation and from there further explore securitisation theory and its limits. It takes aim at how the audience and its agency is conceptualised in the theory and develops the notions of ‘historical resources’ and ‘activation architecture’ to more adequately explain the processes of securitisation.
Firms falling short of earnings expectations are more likely to cite stakeholder-focused objectives in their public communications following earnings announcements. This behavior is consistent with managers preferring to be evaluated by subjective stakeholder-based performance criteria when falling short on objective shareholder-based measures. This increased use of stakeholder language is most evident among firms narrowly missing earnings estimates and appears unrelated to a firm’s actual environmental, social, and governance (ESG)-related activity. Stakeholder language appears to influence the evaluation of CEOs; turnover–performance sensitivity is lower for managers citing stakeholder value. Collectively, our findings are consistent with concerns that stakeholder objectives reduce managerial accountability for poor performance.
In utero idiopathic constriction of the arterial duct is a rare condition with only a handful reported cases. Ductal aneurysms with thrombus formations on the other hand are significantly more common. We report a case of a term infant who presented with right heart failure due to premature ductal closure and postnatal severe respiratory distress. Subsequent diagnostics revealed paresis of left laryngeal nerve and obstruction of the left pulmonary artery secondary to a ductal aneurysm. Consequently, surgical intervention was considered necessary. Post-operatively, right ventricular function and hoarseness resolved slowly.
