The Ottoman state and the Armenian Patriarchate of Constantinople during the mid-19th-century Tanzimat reform era relied on ethno-confessional and gendered differences, new administrative organization, and coercive institutions like the police to centralize and expand their power. Yet Armenian men and women used those same tools of power to seek justice in ways that created instances of disorder for their families, local community, the church, and the Ottoman state. Attending to the voices and experiences of Armenians through untapped petitions from Erzurum, Mush, and Van, this article highlights the ways in which provincial Armenians interacted with and navigated their diverse ethno-confessional milieus.
Abject breath, running over with its own refuse and yet refusing to stop breathing, forms a gasping undertone to Beckett’s oeuvre. To give a sense of the longevity and development of Beckettian respiration, this article examines passages across the range of his career, paying attention to several prose works – the short story ‘Dante and the Lobster’ (1934) and the novels Murphy (1938) and Molloy (1951/55) – and two brief plays: Breath (1969) and Not I (1972). While there is no simple development of Beckett’s writing on the breath, an ambiguous movement can be traced from an initial rejection of a conception of the breath as immaculate and easeful to a deeper exploration of breath as polluted and broken, and to a final, insistent association of respiration with rubbish, and life with death. If there is hope to be found in the Beckettian breath, it lies not on the page but in the breath-carried conversations of the rehearsal room, exemplified above all by his collaboration with Billie Whitelaw on Not I.
The training that the Saratoga International Theater Institute (SITI) perfected during its thirty years of existence is its most relevant heritage. SITI believed that training was a crucial part of a performer’s education and ethos. Its constitutive elements – Viewpoints and the Suzuki Method for actor training – are here put in a dialectical opposition that nurtures hybridization. This article investigates how, in fact, these two trainings intersect and also form new ‘languages’ (that is, systems of representation) whenever they are performed. A contextual analysis of SITI’s training as a foundation for making work and as a means for educating actors provides a clearer understanding of why and how SITI training is an instrument that facilitates and fosters cross-cultural collaboration.
Several decades ago, Sig Prais concluded that the root cause of the UK’s poor industrial performance was the poor quality of education and training. In this lecture, I will make a related argument, focussing on the lack of opportunity in the United Kingdom for workers who have not succeeded in the formal education system and the long-lasting impacts this has on their economic, health and social wellbeing. I will highlight the importance of providing opportunities for continued training over a worker’s lifetime for appropriate skills that are valued in the workplace in order to achieve inclusive growth.
The New Model Institute for Technology and Engineering (NMITE) reflects a systematic attempt to rethink what a higher education (HE) institution should look like, based on the best globally competitive models. NMITE has been designed as a model for a small, new, distinctive, open, academically rigorous, skills-based local university. Many cities or large towns across the UK have low economic growth and low value-added per capita, and little or no access to HE. Addressing this gap in attainment successfully would be both equitable and highly economically and culturally advantageous. It would be a major contribution to local people, local communities and to raising regional and national productivity.
Direct numerical simulations have been conducted to investigate turbulent Rayleigh– Bénard convection (RBC) of liquid metal in a cuboid vessel with aspect ratio $\varGamma =5$ under an imposed horizontal magnetic field. Flows with Prandtl number $Pr=0.033$, Rayleigh numbers ranging up to $Ra\leq 10^{7}$, and Chandrasekhar numbers up to $Q\leq 9 \times 10^6$ are considered. For weak magnetic fields, our findings reveal that a previously undiscovered decreasing region precedes the enhancement of heat transfer and kinetic energy. For moderate magnetic fields, we have reproduced the reversals of the large-scale flow, which are considered a reorganization process of the roll-like structures that were reported experimentally by Yanagisawa et al. (Phys. Rev. E, vol. 83, 2011, 036307). Nevertheless, the proposed approach of skewed-varicose instability has been substantiated as insufficient to elucidate fundamentally the phenomenon of flow reversal, an occurrence bearing a striking resemblance to the large-scale intermittency observed in magnetic channel flows. As we increase the magnetic field strength further, we observe that the energy dissipation of the system comes primarily from the viscous dissipation within the boundary layer. Consequently, the dependence of Reynolds number $Re$ on $Q$ approaches a scaling as $Re\,Pr/Ra^{2/3} \sim Q^{-1/3}$. At the same time, we find the law for the cutoff frequency that separates large quasi-two-dimensional scales from small three-dimensional ones in RBC flow, which scales with the interaction parameter as ${\sim }N^{1/3}$.
The stigma faced by unemployed Americans places a toll on their wellbeing and decreases their life chances. While all unemployed Americans are subject to stigmatization, the stigma levied on Black Americans may be particularly potent due to racializing stereotypes that associate Blackness with the undeserving poor, including the inability to obtain employment. Given the social and economic challenges Black people face, research elucidating the racial complexities of unemployment stigma is needed. Through in-depth open format face-to-face interviews of unemployed individuals residing in urban and suburban areas, this study produces an alternative perspective on how impression management techniques are connected to both internalization and mitigation of unemployment stigma. This study contributes to employment, race, and stigma literature by providing a theoretical frame that synthesizes Du Boisian and dramaturgical concepts to conceptualize an “unemployed worker-self.” Through this framing, I find variations across race and community type in impression management techniques executed by unemployed people. I conclude with suggestions for future research and potential applications for the theoretical frame developed in this study.
Cognitive behavioural therapy (CBT) is an empirically supported treatment for generalized anxiety disorder (GAD). Little is known about the effectiveness of CBT for GAD in real-world treatment settings.
Aim:
This study investigated the effectiveness of group CBT and predictors of treatment response in an out-patient hospital clinic.
Method:
Participants (n = 386) with GAD participated in 12 sessions of group CBT at an out-patient clinic. Of those who provided at least partial data (n = 326), 84.5% completed treatment. Most questionnaires were completed at pre- and post-treatment; worry severity was assessed weekly.
Results:
Group CBT led to improvements in chronic worry (d = –0.91, n = 118), depressive symptoms (d = –1.22, n = 172), GAD symptom severity (d = –0.65, n = 171), intolerance of uncertainty (IU; d = –0.46, n = 174) and level of functional impairment (d = –0.35, n = 169). Greater pre-treatment GAD symptom severity (d = –0.17, n = 293), chronic worry (d = –0.20, n = 185), functional impairment (d = –0.12, n = 292), and number of comorbid diagnoses (d = –0.13, n = 299) predicted greater improvement in past week worry over treatment. Biological sex, age, depression symptom severity, number of treatment sessions attended, and IU did not predict change in past week worry over time.
Discussion:
These findings provide support for the effectiveness of group CBT for GAD and suggest the outcomes are robust and are either not impacted or are slightly positively impacted by several demographic and clinical factors.
In an effort to capture the continuous hydraulic jump and flow structure for a jet impinging on a disk, we recently proposed a composite mean-field thin-film approach consisting of subdividing the flow domain into three distinct connected regions of increasing gravity strength (Wang et al., J. Fluid Mech., vol. 966, 2023, A15). In the present study, we further validate our approach, and examine the characteristics and structure of the circular jump and recirculation. The influence of the disk radius is found to be significant, especially in the subcritical region. Below a disk radius, the jump transits from type Ia to type 0 after the recirculation zone has faded. The supercritical flow and jump location are insensitive to the disk size, but the jump length and height as well as the vortex size are strongly affected, all decreasing with decreasing disk radius, exhibiting a maximum with the flow rate for a small disk. The jump is relatively steep with a strong recirculation zone for a high obstacle at the disk edge. Comparison against the Navier–Stokes solution of Askarizadeh et al. (Phys. Rev. Fluids, vol. 4, 2019, 114002; Intl J. Heat Mass Transfer, vol. 146, 2020, 118823) for the weak and intermediate surface tension suggests that the surface tension effect is unimportant for a high obstacle for a jump of type 0 or type Ia. The film thickness at the disk edge for a freely draining film is found to comprise, in addition to a static component (capillary length), a dynamic component: ${h_\infty }\sim {(Fr/{r_\infty })^{2/3}}$ that we establish by minimizing the Gibbs free energy at the disk edge, and, equivalently, is also the consequence of the flow becoming supercritical near the edge. By assuming negligible film slope and curvature at the leading edge of the jump and maximum height at the trailing edge, we show that the jump length is related to the jump radius as ${L_J}\sim Re{(F{r^2}/{r_J}^5)^{1/3}}$. The vortex length follows the same behaviour. The energy loss and conjugate depth ratio exhibit a maximum with the flow rate, which we show to originate from the descending and ascending branches of the supercritical film thickness. The presence of the jump is not necessarily commensurate with that of a recirculation; the existence of the vortex closely depends on the upstream curvature and steepness of the jump. The surface separating the regions of existence/non-existence of the recirculation is given by the universal relation $R{e^{10/3}}F{r^2} = 9r_\infty ^9/50$. The jump can be washed off the edge of the disk, particularly at low viscosity and small disk size. The flow in the supercritical region remains insensitive to the change in gravity level and disk size but is greatly affected by viscosity.
Plane unsteady potential flows of an ideal incompressible fluid with a free boundary are considered in the absence of external forces and surface tension. Examples of exact solutions in situations where the entire boundary of the domain occupied by the fluid is completely free are constructed. There may be polar singularities of the complex velocity function inside the fluid, which corresponds to the presence of a source or a sink there.
A theoretical and computational study analysing the initiation of yield-stress fluid percolation in porous media is presented. Yield-stress fluid flows through porous media are complicated due to the nonlinear rheological behaviour of this type of fluid, rendering the conventional Darcy type approach invalid. A critical pressure gradient must be exceeded to commence the flow of a yield-stress fluid in a porous medium. As the first step in generalising the Darcy law for yield-stress fluids, a universal scale based on the variational formulation of the energy equation is derived for the critical pressure gradient which reduces to the purely geometrical feature of the porous media. The presented scaling is then validated by both exhaustive numerical simulations (using an adaptive finite element approach based on the augmented Lagrangian method), and also the previously published data. The considered porous media are constructed by randomised obstacles with various topologies; namely square, circular and alternatively polygonal obstacles which are mimicked based on Voronoi tessellation of circular cases. Moreover, computations for the bidispersed obstacle cases are performed which further demonstrate the validity of the proposed universal scaling.
The first stages of the path instability phenomenon affecting the buoyancy-driven motion of gas bubbles rising in weakly or moderately viscous liquids are examined using a recently developed numerical approach designed to assess the global linear stability of incompressible flows involving freely evolving interfaces. Predictions for the critical bubble size and frequency of the most unstable mode are found to agree well with reference data obtained in ultrapure water and in several silicone oils. By varying the bubble size, stability diagrams are built for several specific fluids, revealing three distinct regimes with different bifurcation sequences. The spatial structure of the unstable modes is analysed, together with the variations of the bubble shape, position and orientation. For this purpose, displacements of the bubble surface are split into rigid-body components and volume-preserving deformations, allowing us to determine how the relative magnitude of the latter varies with the fluid properties and bubble size. Predictions obtained with freely deformable bubbles are compared with those found by maintaining the bubble shape determined in the base state frozen during the stability analysis. This comparison reveals that deformations leave the phenomenology of the first bifurcations unchanged in low-viscosity fluids, especially water. Hence, in such fluids, bubbles behave essentially as freely moving rigid bodies submitted to constant-force and zero-torque constraints, at the surface of which the fluid obeys a shear-free condition. In contrast, deformations change the nature of the primary bifurcation in oils slightly more viscous than water, whereas, somewhat surprisingly, they leave the near-threshold phenomenology unchanged in more viscous oils.
