Eternal peace, perpetual war? A critical investigation into Kant's conceptualisations of war

Most discussions of Immanuel Kant's political theory of international politics focus on his work on Eternal Peace and its normative and empirical relevance for contemporary international relations and international law. Yet for all his concern with peace, Kant's work is characterised by a fascinating preoccupation with the concept of war and its role in human history. The purpose of this essay is to investigate critically Kant's different conceptualisations of war and to evaluate his writing as a critique against contemporary versions of Liberal war and peace, as well as recent attempts to reduce war to an immanent logic of biopolitics.

Political economy of state-building: power after peace

The purpose of this volume is to examine and evaluate the impact of international state-building interventions on the political economy of post-conflict countries over the last 20 years. It analyses how international interventions have shaped political and economic dynamics and structures – both formal and informal – and what kind of state, and what kind of state-society relations have been created as a result, through three different lenses: first, through the approaches taken by different international actors like the UN, the International Financial Institutions, or the European Union, to state-building; second, through detailed analysis of key state-building policies; and third, through a wide range of country case studies. Amongst the recurring themes that are highlighted by the book’s focus on the political economy of state-building, and that help to explain why international state-building interventions have tended to fall short of the visions of interveners and local populations alike are evidence of important continuities between war-time and “post-conflict” economies and authority structures, which are often consolidated as a consequence of international involvement; tensions arising from what are often the competing interests and values held by different interveners and local actors; and, finally, the continuing salience of economic and political violence in state-building processes and war-to-peace transitions. The book aims to offer a more nuanced understanding of the complex impact of state-building practices on post-conflict societies, and of the political economy of post-conflict state-building.

The United Nations and the African Union: Assessing a partnership for peace in Darfur

In Resolution 1556, the Security Council, with the conflict in Darfur clearly in mind, determined that the ‘situation in Sudan constitutes a threat to international peace and security and to stability in the region’. This article focuses on the response by the United Nations, in particular the Security Council, and the African Union to the Darfur conflict. It begins by exploring the role of peacekeeping operations and regional arrangements or agencies in the overarching architecture of international peace and security. Having laid this frame of reference, it then looks at the modalities of peacekeeping in Darfur. These operations began with the African Union acting in isolation but have transitioned to an increasingly important role being played by the United Nations and a hybrid peacekeeping presence. Finally, this article asks whether, assuming that a legally dispositive conclusion can be drawn that genocide has taken place in Darfur since the outbreak of hostilities there in 2003, there exists a legal justification, or even obligation, for non-compliance by states with the sanctions regime established by Security Council Resolutions 1556 and 1591. This regime of sanctions has played an important part in the Security Council's approach to Darfur but has been, unfortunately, left largely unexamined from the standpoint of international legality.

Survival and vigour of ultra-dry seeds after ten years of hermetic storage

Seeds of carrot, groundnut, lettuce, oilseed rape and onion were stored hermetically in laminated aluminium foil packets in four environments (dry or ultra-dry moisture contents combined factorially with temperatures of 20 degrees C or -20 degrees C), replicated at several sites. After ten years' hermetic storage, seed moisture content, equilibrium relative humidity, viability (assessed by ability to germinate normally in standard germination tests) and vigour were determined. After a decade, the change in seed moisture content of samples stored at -20 degrees C was small or nil. Except for groundnut and lettuce (where loss in viability was about 8 and 3%, respectively), no loss in viability was detected after 10 years' hermetic storage at -20 degrees C. In all cases, there was no difference in seed survival between moisture contents at this temperature (P > 0.25). Comparison of seed vigour (root length and rate of germination) also confirmed that drying to moisture contents in equilibrium with 10-12% r.h. had no detrimental effect to longevity when stored at -20 degrees C: the only significant (P < 0.05) differences detected were slightly greater root lengths for ultra-dry storage of four of the six seed lots. Seed moisture content had increased after a decade at 20 degrees C (generally to the level in equilibrium with ambient relative humidity). Hence, sub-zero temperature storage helped maintain the long-term integrity of the laminated aluminium foil packets, as well as that of the seeds within.

Productivity change in Polish agriculture: an illustration of a bootstrapping procedure applied to Malmquist indices

This article illustrates the usefulness of applying bootstrap procedures to total factor productivity Malmquist indices, derived with data envelopment analysis (DEA), for a sample of 250 Polish farms during 1996-2000. The confidence intervals constructed as in Simar and Wilson suggest that the common portrayal of productivity decline in Polish agriculture may be misleading. However, a cluster analysis based on bootstrap confidence intervals reveals that important policy conclusions can be drawn regarding productivity enhancement.

Effect of species and genotype on the efficiency of enrichment of poultry meat with n-3 polyunsaturated fatty acids

The effect of poultry species (broiler or turkey) and genotype (Wrolstad or BUT T8 turkeys and Ross 308 or Cobb 500 broilers) on the efficiency with which dietary longchain n-3 PUFA were incorporated into poultry meat was determined. Broilers and turkeys of both genotypes were fed one of six diets varying in FA composition (two replicates per genotype x diet interaction). Diets contained 50 g/kg added oil, which was either blended vegetable oil (control), or partially replaced with linseed oil (20 or 40 g/kg diet), fish oil (20 or 40 g/kg diet), or a mixture of the two (20 g linseed oil and 20 g fish oil/kg diet). Feeds and samples of skinless breast and thigh meat were analyzed for FA. Wrolstad dark meat was slightly more responsive than BUT T8 (P = 0.046) to increased dietary 18:3 concentrations (slopes of 0.570 and 0.465, respectively). The Ross 308 was also slightly more responsive than the Cobb 500 (P= 0.002) in this parameter (slopes of 0.557 and 0.449). There were no other significant differences between the genotypes. There was some evidence (based on the estimates of the slopes and their associated standard errors) that white turkey meat was more responsive than white chicken meat to 20:5 (slopes of 0.504 and 0.289 for turkeys and broilers, respectively). There was no relationship between dietary 18:3 n-3 content and meat 20:5 and 22:6 contents. If birds do convert 18:3 to higher FA, these acids are not then deposited in the edible tissues.

Frequency of word-use predicts rates of lexical evolution throughout Indo-European history

Greek speakers say "ovpa", Germans "schwanz'' and the French "queue'' to describe what English speakers call a 'tail', but all of these languages use a related form of 'two' to describe the number after one. Among more than 100 Indo-European languages and dialects, the words for some meanings (such as 'tail') evolve rapidly, being expressed across languages by dozens of unrelated words, while others evolve much more slowly-such as the number 'two', for which all Indo-European language speakers use the same related word-form(1). No general linguistic mechanism has been advanced to explain this striking variation in rates of lexical replacement among meanings. Here we use four large and divergent language corpora (English(2), Spanish(3), Russian(4) and Greek(5)) and a comparative database of 200 fundamental vocabulary meanings in 87 Indo-European languages(6) to show that the frequency with which these words are used in modern language predicts their rate of replacement over thousands of years of Indo-European language evolution. Across all 200 meanings, frequently used words evolve at slower rates and infrequently used words evolve more rapidly. This relationship holds separately and identically across parts of speech for each of the four language corpora, and accounts for approximately 50% of the variation in historical rates of lexical replacement. We propose that the frequency with which specific words are used in everyday language exerts a general and law-like influence on their rates of evolution. Our findings are consistent with social models of word change that emphasize the role of selection, and suggest that owing to the ways that humans use language, some words will evolve slowly and others rapidly across all languages.

Exploring teachers' knowledge of children's literature

In the context of the current debate about teaching reading, research to ascertain primary teachers' personal and professional reading practices was undertaken. The study explored teachers' reading habits and preferences, investigated their knowledge of children's literature, and documented their reported use of such texts and involvement with library services. Questionnaire responses were gathered from 1200 teachers. The data were analysed and connections made between the teachers' own reading habits and preferences, their knowledge of children's literature, their accessing practices and pedagogic use of literature in school. This paper reports on part of the dataset and focuses on teachers' knowledge of children's literature; it reveals that primary professionals lean on a narrow repertoire of authors, poets and picture fiction creators. It also discusses teachers' personal reading preferences and considers divergences and connections between these as well as the implications of the teachers' limited repertoires on the reading development of young learners.
