Catecholamines in urine after death.

Noradrenaline, adrenaline and dopamine levels were measured using high-performance liquid chromatography (HPLC) and electrochemical detection and related to urine creatinine in 30 specimens from unselected autopsies. Values calculated from patients with essential hypertension were used as a reference and raised values of noradrenaline, adrenaline and dopamine were found in 76.6, 80 and 23.3%, respectively. Using the Mann-Whitney U test, there was no difference between the 11 patients with myocardial infarction and the seven who died from severe head injury or multiple trauma. The median values in mmol/mol creatinine for patients with myocardial infarction and trauma were 0.07 and 0.12 for noradrenaline and 0.012 and 0.024 for adrenaline, respectively. Physiological stress is common before death and urine noradrenaline values at autopsy overlap those found in some normal subjects and at autopsy in patients with phaeochromocytoma.     

Policy feedback and pathways: when change leads to endurance and continuity to change

Policy Sciences - The policy feedback literature was initially concerned with explaining how positive feedback could lead to self-reinforcing policy trajectories. More recently, policy scholars...     

Reflections on rural violence in Latin America

In recent decades rural violence has escalated in many Latin American countries. Although there is a growing body of literature on the topic, there exist as yet few comparative studies. While there are undoubtedly multiple and evolving causes of violence, this exploratory article focuses on the relationship between sociopolitical violence and agrarian structure and state policy. Particular attention is paid to the impact of agrarian reform and counter-reform experiences on rural conflicts and violence. A contrast is also drawn with countries which have not undergone any significant land reform. The cases discussed are Chile, Peru, Colombia, Brazil, Mexico and several Central American countries (Nicaragua, Guatemala and El Salvador). The complexity of rural violence is demonstrated and the case for further comparative studies is argued, so as to advance our knowledge on the causes, consequences and resolution of violence.     

Partisan Politics and Institutional (Re)Creation: Locating and Explaining the Origins of Modern Finance Capitalism

Why do some countries rely more heavily on equities markets, while others depend more on commercial banking? Analyses of the origins of contemporary capitalist institutions usually look back to the late nineteenth and early twentieth century. However, this paper demonstrates that financial institutions – regarded as central to the way capitalist systems are organised – changed radically in the mid-twentieth century in many countries. This paper argues that government partisanship in formative moments of institutional (re)creation can better account for their modern manifestation than prominent alternative explanations. A new measure of partisanship that is sensitive to these institutional transformations is presented. Case studies on Germany and France offer evidence consistent with this argument.
