Failing to Yield? Ploughs,Conservation Agriculture and the Problem of Agricultural Intensification: An Example from the Zambezi Valley,Zimbabwe

Agricultural intensification, or increasing yield, has been a persistent theme in policy interventions in African smallholder agriculture. This article focuses on two hegemonic policy models of such intensification: (1) the ‘Alvord model’ of plough-based, integrated crop-livestock farming promoted in colonial Zimbabwe; and (2) minimum-tillage mulch-based, Conservation Agriculture, as currently preached by a wide range of international agricultural research and development agencies. An analysis of smallholder farming practices in Zimbabwe's Zambezi Valley, reveals the limited inherent understanding of farmer practices in these models. It shows why many smallholder farmers in southern Africa are predisposed towards extensification rather than intensification, and suggests that widespread Conservation Agriculture adoption is unlikely.     

Pattern detection in forensic case data using graph theory: application to heroin cutting agents

Pattern recognition techniques can be very useful in forensic sciences to point out to relevant sets of events and potentially encourage an intelligence-led style of policing. In this study, these techniques have been applied to categorical data corresponding to cutting agents found in heroin seizures. An application of graph theoretic methods has been performed, in order to highlight the possible relationships between the location of seizures and co-occurrences of particular heroin cutting agents. An analysis of the co-occurrences to establish several main combinations has been done. Results illustrate the practical potential of mathematical models in forensic data analysis.     

HOW TRADITIONAL ARE THE AMERICAN,FRENCH AND GERMAN TRADITIONS OF PUBLIC ADMINISTRATION? A RESEARCH AGENDA

Consistent with the notion of tradition, public administration scholars usually interpret and compare administrative developments in the US, France, and Germany as inheritance, assuming continuity. However, administrative traditions have thus far not been an object of systematic research. The present research agenda aims to address this research gap by introducing the transfer‐of‐ideas approach as a means to examine the empirical substance of national traditions. We claim that for current research, the benefits of this approach are twofold. First, the transfer‐of‐ideas approach contributes to comparative public administration since it reveals in how far intellectual traditions are hybrid instead of distinctively American, French or German developments. Second, the approach may help to address the polysemous meanings of and terminological difficulties within administrative concepts that prevail in Public Administration on both sides of the Atlantic.     

A General Empirical Law of Public Budgets: A Comparative Analysis

We examine regularities and differences in public budgeting in comparative perspective. Budgets quantify collective political decisions made in response to incoming information, the preferences of decision makers, and the institutions that structure how decisions are made. We first establish that the distribution of budget changes in many Western democracies follows a non-Gaussian distribution, the power function. This implies that budgets are highly incremental, yet occasionally are punctuated by large changes. This pattern holds regardless of the type of political system—parliamentary or presidential—and for level of government. By studying the power function's exponents we find systematic differences for budgetary increases versus decreases (the former are more punctuated) in most systems, and for levels of government (local governments are less punctuated). Finally, we show that differences among countries in the coefficients of the general budget law correspond to differences in formal institutional structures. While the general form of the law is probably dictated by the fundamental operations of human and organizational information processing, differences in the magnitudes of the law's basic parameters are country- and institution-specific .     

Structural changes in Central and Eastern European economies: breaking news or breaking the ice?

This paper extends the sparse existing literature on structural breaks in emerging markets in Central and Eastern Europe by analyzing structural breaks in the intercept, trend and variance of monthly key macroeconomic variables, such as industrial production, inflation, monetary aggregates, nominal exchange rates and series related to the labor market. Using the Bayesian procedure developed by Wang and Zivot (2000, A Bayesian time series model of multiple structural changes in level, trend and variance. J Busi Econom 18:374–386), we provide strong evidence in favor of multiple structural breaks in the series under study. As most of the existing empirical literature on European emerging markets does not sufficiently deal with structural breaks, the instability found in this paper has important implications for macro-econometric modeling as well as the ensuing recommendations for economic policy.     

Zwischen Ökonomie und Politik. Zur diskursiven Konstruktion des Begriffs „Sozialmodell“ im Sarkozy-Wahlkampf 2005–2007

In “general economic-political discourses”, actors from the spheres of politics, economics and mass media struggle over the valid perception of the relations between the economy, politics, and society as a whole. The discourse on the “modèle sociale français“ provides a case in point: A concept that had been associated for many years with the economic success of the fifth republic, but in the 2000s became a central element of a crisis-rhetoric that helped to pave the way for the reform agenda of Nicolas Sarkozy. Building on this example, the article analyzes how economic-political discourses are established and transformed. On the one side, it reflects upon the importance of discourse research for economic sociology in general; on the other, it shows how general economic-political discourses help to legitimize certain positions in public debates, and how they depict specific scientific problems as relevant for society. Mediators of public and scientific debates benefit from this, just as political and economic actors do as they generate public approval for their corresponding reform-agendas.     

From Racial Mixture to Black Nation: Racialising Discourses in Brazil's African Affairs

The article links reflections about Brazilian race relations with institutional transnational dialogues between Brazil and ‘Africa’. I point out that although racial/cultural mixture and the ‘brown’ census category have traditionally reflected much of national identity in Brazil, Brazil today is increasingly spelling out its blackness, both on the national and international scenes. I highlight that, not by coincidence, this fact is happening at a historical moment when programmes of ‘black’ affirmative action and other differential politics in favour of Afro‐descendants are taking off in the country, and also at a time when Brazil is expanding its geopolitical and economic interests in Africa.     

Confederates and Yankees under the Southern Cross

Following the Civil War in the United States of America, colonies that were predominately ‘Yankee’ and Confederate sprang up in Brazil. In contrast to the subject's historiography, we seek to show how these colonies were the result of in the first case, the actions of Imperial diplomacy and in the second case, spontaneous interest by Southerners due to the existence of slavery in Brazil. This proposition is supported by primary sources, as they indicate the presence of significant teams of slaves in the Confederate colonies in Brazil, while slavery was prohibited in their ‘Yankee’ counterparts.
