The design-based paradigm may be adopted in causal inference and survey sampling when we assume Rubin’s stable unit treatment value assumption (SUTVA) or impose similar frameworks. While often taken for granted, such assumptions entail strong claims about the data-generating process. We develop an alternative design-based approach: we first invoke a generalized, non-parametric model that allows for unrestricted forms of interference, such as spillover. We define an associated set of inferential targets and discuss their interpretation under SUTVA and a weaker assumption that we call the “no unmodeled revealable variation assumption” (NURVA). We then reconstruct the standard paradigm, reconsidering SUTVA at the end rather than assuming it at the beginning. Despite its similarity to SUTVA, we demonstrate the practical limitations of NURVA alone for identifying substantively interesting quantities. In so doing, we provide clarity on the nature and importance of SUTVA for applied research.
In the National Archives there is a huge roll of stiff cream paper which contains the accounts of the Cranbrook Commissioners appointed to be responsible for the sales of French prizes before the declaration of war. The Treasury was determined that everything was done by the book, although it took until 1769 before finalising their accounts from the war.
Disposing of the captures made before war was declared took place without delay, the announcement taking place in November 1756 that Commissioners had sent ‘proper persons’ to Gibraltar, Barbados, the Leeward Islands, Jamaica and South Carolina to begin the sales in January, so that ‘all merchants inclined to become purchasers, may have time to give orders to their correspondents accordingly’.
First refusal of the prize ship together with its tackle was given to his Majesty's Navy, and guns, arms and ordnance stores were offered to the Board of Ordnance. If accepted at a fair and reasonable valuation, these were paid for by bills or debentures. If rejected, the certificate of the refusal was given to the agent of the captor within six weeks, this certificate entitled the vessel to be considered as British built. The importance of this was that British trade could only be carried in British vessels, so these vessels could cheaply become part of the merchant fleet. The Navy or Victualling Boards were entitled to buy any naval stores without waiting for the condemnation of the vessel.
This chapter sets out to ask difficult questions and to explore how the context of writing, for example exile in the USA, overdetermines how a writer like Ngugi engages his craft. Has Ngugi’s audience shifted during his stay in the USA and what kind of publics is he seeking to hail in his fiction, essays and memoirs? Who reads him? Ngugi’s forced exiled in Europe and the USA has complicated Ngugi’s writing and especially his return to English. Deprived of direct contact with his target audience and working outside the institutions of learning in Africa, Ngugi has been forced to repurpose his works for a new audience.
Beginning with Wizard of the Crow, I argue that Ngugi radicalises the original concept of the novel by situating oral performance at the centre of the scribal narrative genre. The consequence is an epic that is at once the globalisation of an African artistic practice through the appropriation and reinvention of the novel tradition, while addressing critical issues around the politics of dictatorship, rumours, exile and globalisation. By exploiting his childhood and youth memory through a trilogy, Ngugi demonstrates aliveness to the cause of total artistic rendition. This is dramatised by the sense in which wider insights into his oeuvre attain sophisticated vent between fact and fiction in the recollection of the tensions between colonial violence and growth. Although The Perfect Nine is a commitment to myth-making and remaking, it doubles as an treatise on the necessity of environmental conservation. Anchored to multi-species justice, it illustrates mythology’s relevance in the present and justifies its amenability to continual reinvention. Taking Globalectics as representative, the chapter reflects on Ngugi’s transition from the discourse of nationalism to dismantling hierarchies in the production, circulation and reception of world literature by writing against linguistic feudalism. Central to the apparent shift is the primacy of context as informed by the dynamics of the twenty-first century.
The introduction seeks to provide bold outlines of Ngugi’s complex contexts and point to how these offer new paths to his fiction. While acknowledging that scant attention has been paid to the context in which Ngugi’s works are produced, we are also seeking to understand how this context has been mediated by Ngugi’s discourse. To do this is to suggest that Ngugi as a writer of praxis also generates his context and enters into dialogue with familial and historical events, intellectual climate and other layers of institutional practices that have helped him disrupt received knowledges and histories. The contexts, far from offering some objective and reified source of knowledge, are an engagement with a society and historical moment in flux and in need of reinterpretation. One aim of this introduction is to displace our notion of context as a reified site of retrieval; another is to see how context offers readers a handle on new and disruptive ways of rereading Ngugi’s texts. I argue that contexts, whether one is thinking of family, mission education or Mau Mau emergency and related colonial experiences, are not muted sites of knowledge, nor are they self-evident sources of meaning and meaning-making, but a seething site of creativity and meaning-making.
Most South African readers will be members of a medical aid scheme providing access to private healthcare. There are a wide range of schemes available offering different levels of benefits which are paid for by members’ monthly contributions. “Day-to-day” medication and treatment benefits smooth what would otherwise be payments made by the member directly. Schemes also provide cover for more serious health problems requiring hospitalisation, operations, or other major expenses. Having medical aid means not having to use South Africa's public healthcare system characterised by long queues, rundown facilities, limited treatment, and indifferent service.
Medical aid membership is not cheap, even for the most basic schemes. Under 20 per cent of the population can afford the comfort and convenience that private health cover provides. The rise of an African middle class in postapartheid South Africa has diversified the racial profile of scheme membership. However, there are township residents who have medical aid despite their salaries not being close to professional levels. This is because they work for private or public organisations that require membership as a condition of service. In public sector organisations there has been significant growth in medical aid membership, even as the percentage of the population with membership has changed little over the last twenty years.
For medical aid to be affordable for non-professional workers, the employer must subsidise monthly contributions. Yet, even with subsidisation and when employees are on cheaper schemes, contributions nevertheless represent a significant deduction from pay packets.
Contributions cover a capped day-to-day set of benefits as well as possible major expenses, including the statutorily required prescribed minimum benefits that must be offered by medical aids, as well as the administrative costs of the scheme.
In December 1808, Joseph Atkinson published verses in the Cyclopaedian Magazine to mark the season of ‘Private Theatricals’ held in Kilkenny during the previous October. Atkinson duly acknowledged both the participation of Thomas Moore in these theatricals and the nascent fame of Moore's Irish Melodies, the first volume of which had appeared in April that year:
The girls and the boys of Kilkenny have long Tun’d Erin's sweet harp and enraptur’d her song… Then Moore came the lyre of Apollo to string, And give us pure draughts of the Helicon spring; And the banks of the Nore shall long echo the lays That his melodies breathe to record Erin's praise.
Atkinson's poetic vein may have been slight (not to say ephemeral and metrically cumbrous), but the compound of classical and Irish metaphors engaged in these lines to celebrate Moore is striking nevertheless: the ‘sweet harp’ of Erin and the ‘lyre of Apollo’ are in close apposition, and so too (by extension) are the ‘banks of the Nore’ (in Kilkenny) and the slopes and springs of Mount Helicon (in Greece). Although the Melodies had only recently begun to appear (their serial publication would continue until 1834), Moore in these lines is all but the Bard of Erin already, at least to judge by the enthusiastic tone of Atkinson's encomium and the fame it predicts for the songs themselves.
The items in this concert of 21 March were Mozart's Symphony no. 40 in G minor (K.550), two movements from Mendelssohn's oratorio Saint Paul, a concertino by Vogt for oboe and orchestra, played by Verroust, the ‘Dies irae’ from Cherubini's Requiem in C minor and Beethoven's Second Symphony.
Mozart's Symphony in G minor, as usual, gave the greatest pleasure, and the minuet was encored. The excerpts from Mendelssohn's oratorio Saint Paul were as yet unknown to me, and I’m at a loss to understand why there's been such a delay in bringing this fine work to Paris when England, Germany, and even some cities in regional France have given complete performances of it some time ago. Whatever the reason, the two extracts brought to us last Sunday are admirable compositions. The first chorus in E-flat, accompanied by a repeated pattern on the first violins, is couched in a calm and a purity that are truly angelic; if this is not religious music, then such a thing has never existed. The harmony is silky, the style of the melody, tender and suave, lends a further charm to the timbre of the cellos, and the incessant accompaniment of the first violins decorates the ensemble, without disturbing its gentle gravity. The form of the work is also highly distinguished: the orchestra and choir are not always combined, sometimes the orchestra is silent, allowing the voices to sing unaccompanied, and sometimes on the contrary it's the orchestra that's heard on its own. Then there are those effects of half-tint and pianissimo which only the greatest composers know how to obtain from such large forces. In a word, this choral work is, in my view, a true masterpiece, a product of inspiration and technique, beautiful, irreproachable, complete.
Irish traditional music is performed by people of all genders, ethnicities, sexualities, and abilities, but a quick perusal of a festival lineup, an array of CDs, or a few live instrumental music sessions would imply that the craft is primarily the preserve of white heterosexual cisgender men. This book will correct that error in perception. In any study of a contemporary music scene, readers deserve the authority of one whose status is that of long-time participant-observer. Joanne Cusack, a gifted performer on the button accordion and long-time participant in multiple Irish music scenes, has used her skills in observation, description, and analysis to understand the multiple approaches that women have taken to be heard and to connect with other musicians.
Women in Irish Traditional Music is very much of-the-moment in terms of its analysis. It does so with compelling, effective language that clearly grasps the specific policies and social mechanisms holding women in an uneasy in-between position regardless of their playing abilities or their status within the community. Everyone who has been to an instrumental music session has observed or experienced some of what Joanne Cusack describes, but few know the specifics of how the professional Irish traditional music world works from an educated insider viewpoint.
What sets this book apart from others is its focus on specific case studies concerning women, its direct engagement of the reader, and its refreshing look at some of the unique challenges faced by women.
In the 1820s, newspapers, religious tracts, pamphlets, magazines, and books became available in vast, affordable quantities to Americans across all classes. This print revolution occurred because of expanding literacy rates, new industrial technologies for mass production, population growth, new transportation modes for wider distribution, and the new Jacksonian ideology of populist democracy. Fiction became especially popular in book form and serialized in magazines and newspapers. After the Civil War, the publishing industry consolidated, and an efficient, interlocked network of syndicates, subscription sales, and door-to-door salesmen popularized the leading authors of the day. Perhaps more germane to the “democratizing” role of nineteenth-century publishing were the penny press and the dime novel. Each offered newspapers or books for cheap prices, making their literature available to urban working classes. This rich, diverse volume of nineteenth-century print culture established the dynamics of American popular culture.
Coastal policing – firmly focused on the idea of ‘prevention’ – was a set of institutions and actors designed to deal with contingencies, that is to say, incidences and potential events beyond the immediate grasp of central authorities, such as smuggling or military invasion. This, however, is not to say that these incidences were not to some extent directly or indirectly influenced by policies implemented by these same authorities. In terms of imperial policies (both within the British archipelago and beyond) and relative to the politics of warfare, many effects materially – though often unintentionally – interfered with regular arrangements of coastal policing. Trade politics and tariff systems directly affected Customs business in the ports of Ireland, Scotland and England. Underneath these fiscal concerns, these policies also impacted on the forms and patterns of Customs activity. Imperial trading routes, the channelling of goods by mercantilist policies, and the micro-logistics of their transport (both lawful and clandestine) and their warehousing affected both the spatial organization and the practical requirements of Customs policing and control in technical and procedural terms. This is also true for the repercussions of wartime arrangements throughout the period. Concerns over coastal defences in particular reordered government priorities vis-à-vis the coast to the disadvantage of the regular peacetime functions and arrangements of the Customs. At the same time, preventive officers became themselves part of the war machinery for the purposes of anti-espionage provisions, the works of the press gangs, or – in the case of the cruisers conscripted by the Admiralty – naval combat.
Graph bootstrap percolation is a discrete-time process capturing the spread of a virus on the edges of Kn. Given an initial set G ⊆ Kn of infected edges, the transmission of the virus is governed by a fixed graph H: in each round of the process, any edge e of Kn that is the last uninfected edge in a copy of H in Kn gets infected as well. Once infected, edges remain infected forever. The process was introduced by Bollobás in 1968 in the context of weak saturation and has since inspired a vast array of beautiful mathematics. The main focus of this survey is the extremal question of how long the infection process can last before stabilising. We give an exposition of our recent systematic study of this maximum running time and the inuence of the infection rule H. The topic turns out to possess a wide variety of interesting behaviour, with connections to additive, extremal, and probabilistic combinatorics. Along the way, we encounter a number of surprises and attractive open problems.
In this chapter, I test the book’s first two hypotheses regarding which leaders contribute to regional security operations and receive support from co-members in return. I expect that leaders with the greatest need for RIOs’ protective benefits – heads of state facing high coup risk – are the most motivated to remain in good standing with co-members who are able to intervene on their side during security crises. In statistical analyses at the RIO-state-year level of analysis, I find that leaders most prone to irregular removal through coups are indeed more likely to deploy security personnel in support of co-members. The chapter also presents tests of the second hypothesis derived from the theory: that leaders who contribute personnel to support RIO co-members increase their odds of receiving protection. Quantitative tests again provide evidence consistent with the theory. The RIO co-members are more likely to deploy troops in support of leaders with prior records of security cooperation in these four RIOs with mutual defense pacts.
Four species of Lygus bugs (Hemiptera: Miridae), Lygus lineolaris, L. keltoni, L. elisus, and L. borealis, are native pests of many crops throughout North America. In eastern Canada, a European parasitoid, Peristenus digoneutis (Hymenoptera: Braconidae), occurs adventively from intentional releases made in the 1980s in the northeastern region of the United States of America. In the Canadian prairies, P. mellipes and P. howardi are common native parasitoids that attack the first and second generations of Lygus, respectively, albeit at low levels. Therefore, relocation of P. digoneutis has been considered to enhance biological control in western Canada. We investigated the potential for competition between the native and exotic Peristenus spp. in laboratory settings. Our results showed that no statistically significant effects of simultaneous or sequential competition occurred on the success of parasitism by the native species, particularly for P. howardi. Minor reductions in parasitism by P. mellipes were observed only when the exotic species was added one day before the native species. From these findings, we conclude that the risk for competitive displacement of native Peristenus spp. by P. digoneutis is low. The potential benefits of having a parasitoid with two generations and the likely additive mortality effects on Lygus bug pests should outweigh the low environmental risks of introducing P. digoneutis.
