Can “Tactical Economics” Help the U.S. Army “Win in a Complex World?” Addressing Army Warfighting Challenges with an Evidence-Based Approach

Economic interventions are a key component of stability operations. But they have proven challenging for the U.S. military to both implement and evaluate under conditions of state fragility and conflict. As a shaping operation, so-called ‘tactical economics’ can enable military units to shape security environments and consolidate gains in pursuit of sustainable outcomes. However, they require careful targeting, design, implementation, and evaluation

El canto de la tierra: W. H. Hudson y el estado natural

Against the backdrop of the ecological crisis spawned by modern progress, literature has renewed its representations of the Golden Age and of the lost organic community. The anglo-argentine writer W. H. Hudson, in his novel Green Mansions (1904), offers an early exploration of today's greatest ecological catastrophe: the destruction of South America's rainforests, pitting the idealistic but destructive invasion of Abel, the modern man, against the state of nature of the bird-girl Rima. Rima's call can still be heard at the beginning of the third millenium after Christ

Livestock disease management for trading across different regulatory regimes

The maintenance of livestock health depends on the combined actions of many different actors, both within and across different regulatory frameworks. Prior work recognised that private risk management choices have the ability to reduce the spread of infection to trading partners. We evaluate the efficiency of farmers' alternative biosecurity choices in terms of their own-benefits from unilateral strategies and quantify the impact they may have in filtering the disease externality of trade. We use bovine viral diarrhoea (BVD) in England and Scotland as a case study, since this provides an example of a situation where contrasting strategies for BVD management occur between selling and purchasing farms. We use an agent-based bioeconomic model to assess the payoff dependence of farmers connected by trade but using different BVD management strategies. We compare three disease management actions: test-cull, test-cull with vaccination and vaccination alone. For a two-farm trading situation, all actions carried out by the selling farm provide substantial benefits to the purchasing farm in terms of disease avoided, with the greatest benefit resulting from test-culling with vaccination on the selling farm. Likewise, unilateral disease strategies by purchasers can be effective in reducing disease risks created through trade. We conclude that regulation needs to balance the trade-off between private gains from those bearing the disease management costs and the positive spillover effects on others

Nature tourism and Irish film

This article provides a historical overview and reading of seminal Irish film from the perspective of nature tourism. Within Irish cultural studies, tourism is frequently equated with an overly romantic image of the island, which has been used to sell the country abroad. However, using notions like the tourist gaze and taking on board influential debates around space/place, one can posit a more progressive environmental vision of nature and landscape in our readings of film

Modelling the Impact and Control of an Infectious Disease in a Plant Nursery with Infected Plant Material Inputs

The ornamental plant trade has been identified as a key introduction pathway for plant pathogens. Establishing effective biosecurity measures to reduce the risk of plant pathogen outbreaks in the live plant trade is therefore important. Management of invasive pathogens has been identified as a weakest link public good, and thus is reliant on the actions of individual private agents. This paper therefore provides an analysis of the impact of the private agents’ biosecurity decisions on pathogen prevention and control within the plant trade. We model the impact that an infectious disease has on a plant nursery under a constant pressure of potentially infected input plant materials, like seeds and saplings, where the spread of the disease reduces the value of mature plants. We explore six scenarios to understand the influence of three key bioeconomic parameters; the disease’s basic reproductive number, the loss in value of a mature plant from acquiring an infection and the cost-effectiveness of restriction. The results characterise the disease dynamics within the nursery and explore the trade-offs and synergies between the optimal level of efforts on restriction strategies (actions to prevent buying infected inputs), and on removal of infected plants in the nursery. For diseases that can be easily controlled, restriction and removal are substitutable strategies. In contrast, for highly infectious diseases, restriction and removal are often found to be complementary, provided that restriction is cost-effective and the optimal level of removal is non-zero

'Hail England old England my country & home': Englishness and the Local in John Clare’s Writings

This article rethinks John Clare's connection to place, as well as the concepts of ‘place’ and ‘the local’ themselves. It argues that the localism of his work was enabled by potential alienation and displacement and was connected to a sense of wider national community. Clare's writings attempt to think of England in two related ways: as a political community brought together at times of threat, and as a community of taste brought together by a way of apprehending the natural world. His early patriotic verse is often strained and unconvincing, but poems such as ‘The Flitting’ present an idea of ‘native poesy’ that embodies the local and the national through careful description of the natural world. However, this idea was itself mediated through metropolitan attempts to reclaim the customs and literature of ‘merry England’. Thus Clare's localism and nationalism are shown to be ambivalent and uncanny

First report of generalized face processing difficulties in möbius sequence.

Reverse simulation models of facial expression recognition suggest that we recognize the emotions of others by running implicit motor programmes responsible for the production of that expression. Previous work has tested this theory by examining facial expression recognition in participants with Möbius sequence, a condition characterized by congenital bilateral facial paralysis. However, a mixed pattern of findings has emerged, and it has not yet been tested whether these individuals can imagine facial expressions, a process also hypothesized to be underpinned by proprioceptive feedback from the face. We investigated this issue by examining expression recognition and imagery in six participants with Möbius sequence, and also carried out tests assessing facial identity and object recognition, as well as basic visual processing. While five of the six participants presented with expression recognition impairments, only one was impaired at the imagery of facial expressions. Further, five participants presented with other difficulties in the recognition of facial identity or objects, or in lower-level visual processing. We discuss the implications of our findings for the reverse simulation model, and suggest that facial identity recognition impairments may be more severe in the condition than has previously been noted
