Emigration has been a central feature of Highland history over the last three centuries and, for much of that period, the scale of outward movement was significantly greater than that from other areas of Scotland. Clearances, commercialisation, demographic pressures, famine, economic collapse and landlordism all had an impact on the emigration process, though there is much debate among scholars about the precise and relative significance of these various influences. After the end of the Napoleonic Wars, the economic and demographic pressures on the population perceptibly increased. The landlord role was often crucial in translating the social crisis into high levels of emigration and also in fashioning the composition and structure of the emigrant parties and this was not only because proprietors covered transport costs. Landlord pursuit of profit and the ensuing commercialisation of estates were the main reasons for the development of mass emigration in the first place.
This chapter examines the rise of two new, and related, forms of international relations that simultaneously bolstered and bypassed traditional channels of diplomacy: aid and humanitarianism. It describes the powerful impact the Biafran humanitarian crisis had on inter-state relations, shifting aid and emergency relief to centre stage in the ‘fire brigade’ states’ relationship with the developing world. Diplomatic support for the decolonisation process was translated into economic and humanitarian support for ailing independent states. But, as this chapter shows, this shift was significant primarily because it was accompanied by the emergence of a new global discourse on aid and humanitarianism, and a new group of transnational actors whose work bypassed traditional political structures to emphasise the power of ‘people-to-people’ action: NGOs.
where $\Delta _\infty ^h$ denotes the h-degree infinity Laplacian, $f\in C(\Omega \times \mathbb {R}\times \mathbb {R}^n)$ satisfies $ 0\leq f(x,\delta t,p)\leq \Lambda (x)\delta ^{\gamma }f(x,t,p),$ a positive function $\Lambda (x)\in C(\overline {\Omega }), \, \gamma \in [0,h), \,t>0$, and $\delta>0 $ is small enough. Such an equation may cause a dead-core region, that is, an unknown region where the nonnegative solution vanishes completely. We establish a flattening estimate for the viscosity solution and obtain sharp $C^{({h+1})/({h-\gamma })}$-regularity along the free boundary $\partial \{u>0\}\cap \Omega .$ Using the sharp regularity, we prove Liouville-type theorems for the global solution and give the porosity of the free boundary. In the end, for the limit case $\gamma =h,$ we show that if the viscosity solution vanishes at a point, then the dead-core region must vanish.
Network meta-analysis is the established method to pool evidence from multiple clinical trials and make direct and indirect comparisons between different treatments. To ensure its validity, one of the major assumptions requiring examination is that the different sources of information are consistent, which is to say that the direct and indirect effect estimates agree. There are at least three different aspects to consider: (1) the original effect sizes of the direct and indirect treatment effects and their relative contribution to the total evidence; (2) the difference between them and its associated uncertainty/significance; and (3) the type of difference between them, that is, whether the direct and indirect estimates agree that a treatment is beneficial or harmful. Current visualization approaches typically use forest plots or heat maps, but these are limited as at least one of the above aspects is usually absent. Furthermore, as the number of treatments in the network increases, these visualizations can become difficult to understand. We present a visualization that combines the three aspects without being too difficult to interpret, outline the mathematical background and provide the code to produce it in R.
The Chiapas rebellion in 1994 signalled a rupture with both the political and visual marginalisation of the indigenous peoples in Mexico. Antonio Turok's black-and-white photographs of the beginning of the uprising were among the photographs that were reproduced endlessly on various websites, including that of the Zapatistas. The photographs constitute the core of a photobook entitled Chiapas: The End of Silence, a collection of photographs taken in Chiapas, Mexico from 1973 to 1994. This chapter examines the way the book informs us about the everyday life of the ethnic communities in Mexico and, most importantly, considers the ways in which the book enhances our understanding of the Zapatista struggle. It compares the photobook with stereotypical photographic representations of Mexican twentieth-century photography and seeks to evaluate the contribution of Turok's book to the understanding of the indigenous people's struggle.
The English poet Richard Aldington and his wife, the American poet Hilda Doolittle (H. D.), became modernist writers who in different ways explored the boundaries of both identity and textual representation. The issue of textual representation is a central concern for both writers. But while feminist scholars over the last twenty years have stressed H. D.'s attention to gender in her work, Aldington's attitudes towards both textuality and sexuality are misrepresented as conventional and fixed. From its very first page, H. D.'s own war novel, Bid Me to Live, addresses the issue of form, the problem of genre, and the difficulties of identity and textual expression that are, in fact, the novel's central subject. The conflict on which H. D. focuses is at once the Great War and the war between the sexes, while the problem of female utterance stems from the war which defines her through marginalisation and loss.
Flocculation of suspended cohesive particles in turbulence plays a crucial role in various natural and industrial processes. In this study, we carry out direct numerical simulations with a cohesive discrete element method to investigate the evolution of cohesive particle flocs in homogeneous isotropic turbulence. We focus on how particle flocs are formed and destructed in turbulence, and the influences of cohesive strength, particle inertia, particle volume fraction and turbulence intensity. The statistics show that the formation and destruction of cohesive particle flocs vary across different flocculation stages and conditions. At the early developing stage, flocs primarily form through coagulation, where individual primary particles collide and adhere together. As the system approaches equilibrium, floc formation may also proceed via separation, where small flocs detach from larger ones under the conditions of strong cohesive strength, low particle inertia or weak turbulent shear. Under these same conditions, floc destruction occurs predominantly through absorption across all stages, in which smaller flocs are incorporated into larger ones. In contrast, under the opposite conditions, floc destruction shifts to disintegration, where a floc breaks apart into primary particles or two-particle flocs. The probability distribution of the floc lifetime follows an exponential decay. Furthermore, flocs exhibit shorter lifetimes under stronger turbulent shear, larger particle inertia or weaker cohesion, as these conditions promote more frequent destruction. A higher particle volume fraction leads to more frequent floc formation and destruction, thus producing shorter lifetimes. Meanwhile, cohesion between particles markedly extends the floc lifetime compared to lifetimes of non-cohesive particle clusters. Moreover, floc compactness is positively correlated with its lifetime. These findings advance our understanding of the flocculation dynamics of cohesive particles in turbulent flow.
This conclusion presents some closing thoughts on concepts discussed in the preceding chapters of this book. The book illustrates how one of the main sceptical witchcraft texts was constructed and what its relationship to the wider intellectual and literary context of the time was. Francis Hutchinson attacked witchcraft for the very same reason: he regarded it as a dangerous, unsociable and enthusiastic belief system, a disposition hardened by first-hand experience of witchcraft trials and the effects they had on small communities. Although the methodology he employed in the Historical essay was similar to that used by other English sceptics, the structure of the book was shaped by his attempt to influence two sectors of English society. They are the literate lower orders and the judiciary. Hutchinson was concerned with maintaining the welfare of the Church of Ireland as he was with serving the Whig and Hanoverian regime.
Christina Rossetti's relationship to Algernon Charles Swinburne is best remembered for an act of censorship. Edmund Gosse contrasts Swinburne's 'more scientific and elaborate system of harmonies' with Rossetti's 'delicate' and 'naïve' technique, defending Swinburne's masculinity along with his poetic talent by distinguishing it from Rossetti's more feminine approach. In contemporary Victorian criticism poetic influence was perceived to flow from Rossetti to Swinburne, but there was some reverse traffic as well. Even if the dedication overstates the case, evidence of Rossetti's and Swinburne's uneasy affinity survives in their poetry, a less restricted space where their relationship could evolve in ways prohibited in life. Swinburne's poem recasts Rossetti's mysterious female figure as Proserpine, goddess of the underworld. Rossetti's poems are known for their secrecy, and Swinburne plays Rossettian games with mysterious symbols and allusions.
