Introduction Advances in perinatal care in the developed world have resulted in more children living into adulthood with complex chronic health conditions. Transition is a process to improve and maximize the functional status of adolescents via the provision of adequate and appropriate health services in adulthood. This process is frequently disjointed, fragmented and inconsistent and inadequate transition increases morbidity, hospital admissions and urgent interventions. Ten thousand children are diagnosed with hydrocephalus annually in North America. Most survive to adulthood yet there are few transitioning programs and little research data on successful programs for this population. Methods An email survey of paediatric neurosurgical centres in Canada was carried out to establish current transition practices and attitudes for adolescents with hydrocephalus. Data were analyzed descriptively. Results Eleven out of 12 centres responded. The age of transition ranged from 16 to 18 years. Four centres have access to a dedicated Adult Hydrocephalus Clinic. Referral practices vary between centres and we highlight inconsistencies in care to this cohort of patients in Canada. There is little satisfaction among neurosurgeons with current transition arrangements in Canada. Several suggestions were made on how to improve this process. Conclusion We recommend research into the needs of patients with hydrocephalus in order to formalize appropriate standards for transitioning patients with a view to developing national guidelines to standardize the transition process. This will require input from patients, families and the wider medical and allied health professional groups. [ABSTRACT FROM AUTHOR]

We present a formal model of international bargaining between two states in which one government must negotiate with a domestic opposition faction to secure tax revenue for military spending. The model examines how robust the international order is to domestic political crises that activate a stark trade-off to a governing coalition. Namely, offering fiscal relief to stave off domestic revolution can simultaneously undermine the larger international political order by facilitating military spending that can, under some circumstances, result in sizable shifts in the relative distribution of military power between states. We find that two key domestic conditions influence the likelihood of preventive war: the distribution of income within the state's economy and the relative economic stake that opposition groups possess in international settlements.

This article explores how the dramatic expansion of British trade in the decades prior to World War I affected Britain's ability to raise an army. We first develop a simple institutionally based model of British army recruiting which we then perturb by expanding trade while holding all other variables constant. Our theoretical analysis suggests that the expansion of trade would impede Britain's ability to raise an army, a prediction that finds substantial support in the historical record using both quantitative and qualitative analysis. Contrary to the conventional wisdom that trade enhances a state's military power, we find that the expansion of trade did not ease Britain's resource constraints by making labor more freely available for military purposes. Rather, by raising the civilian demand for labor, the expansion of trade made labor more expensive and difficult to mobilize, even as a more effective army became more important to British strategy.
