农村现代化道路的理论探源——对马克思、恩格斯关于农民理论的重新审视

中国农村的现代化实践是一场以马克思主义为指导的探索活动。本文力求将马克思主义关于农民问题的相关理论和实证分析结合起来,论述了马克思等关于农民理论的立足点及其发展,分析了农业集体化道路及其挫折,通过对经典理论的重新审视,进而得出对社会主义农业现代化道路的启示.     

明至清前期海外关系的变化与史学

明至清前期,随着海外关系的变化,史学也表现出不同的特点。明前期,皇朝海外关系是建立在“宣威柔远”政治目的基础之上的。这种关系因郑和一下西洋”的活动达到高潮,史学则因此出现了几部反映这种海外关系特点的著作。晚明,倭患问题与私人违禁进行海外商贸等问题交织在一起,经权衡利弊,皇朝开始改变初期的海禁政策,私人海外贸易迅速发展;与此同时．西方殖民者东来,与中国开始发生直接的接触;随着传教士“精神狩猎”的开始,中西文化交流逐渐展开。这些海外关系的特点,都在史学中得到体现。清前期是海外关系大倒退的时期,中西文化交流逐渐偃息,史学的发展也受到影响。     

Development Imperative,Terrae Incognitae: a Pioneer Soil Scientist 1912–1951

James Arthur Prescott was a prominent soil scientist whose career responded to an increasingly complex, recognisably Australian web of interpenetrating spatial scales, served to promote revolutionary global advances in his chosen field, and in the process negotiated the blurred boundaries between ‘pure’ and ‘applied’ research. Encounters with this instructive life suggest that, while resolutions of pivotal anxieties might turn on ineluctably personal qualities, they also reflect a dynamic interplay between international, imperial, national and state contexts. Prescott's innovative contributions to soil science, fruits of a tenaciously consolidated career, influenced resource appraisal and environmental management across a prodigious continental expanse. A sustained focus on local and regional development brought him into contact with a wide range of contemporaries, including pioneering geographers, and culminated in his election to a Fellowship of the Royal Society.     

Spiriferoidea (Brachiopoda) from the Early Permian Del Salto Formation of Argentina

The fossil lycopod Pleuromeia longicaulis (Burges) comb. nov. and its supposed cone Cyclostrobus sydneyensis (Walkom) Helby &; Martin 1965 are common in the Scythian to Anisian Garie and Newport Formations north of Sydney, N.S.W. P. longicaulis probably lived in extensive monodominant stands in the interdistributary bays of the ‘Gosford delta’ system, bordering a large coastal lagoon or lake. C. sydneyensis was borne as a single erect terminal cone. It was shed intact and may have floated some distance before breaking up and releasing its heterospores.

Austrostrobus ornatum Morbelli and Petriella 1973 from southern Patagonia is now included as a further species of Cyclostrobus.

The Pleuromeiaceae appear to have been facultative coastal halophytes. They probably originated in Eurasia and migrated along early Triassic shorelines, reaching eastern Australia by the mid-Scythian. The coastal habitat of the Pleuromeiaceae and other Triassic lycopods explains the biostratigraphic usefulness of the spores Aratrisporites spp., Nathorstisporites hopliticus Jung 1958, and Banksisporites pinguis (Harris) Dettmann 1961 compared with coexisting fully terrestrial fossil floras. These opportunistic lycopods appear to have expanded in times of recovery from global life crises.     

Sustained drought,vulnerability and civil conflict in Sub-Saharan Africa

With climate change projections indicating a likely future increase in extreme weather phenomena, it is an urgent matter to assess the effect of drought on civil conflict. However, studies of this relationship so far provide inconclusive findings. One reason for this inconsistency is that existing research has not sufficiently taken into account the local vulnerability and coping capacity that condition the effect of drought. In particular, the exposure to sustained droughts undermines alternative coping mechanisms of individuals. Moreover, reliance on rainfed agriculture for income and food provision renders individuals particularly vulnerable to droughts. Based on these observations, I suggest that areas experiencing sustained droughts or depending on rainfed agriculture are more likely to see civil conflict following drought as individuals in these regions are more likely to partake in rebellion in order to redress economic grievances or to obtain food and income. Using novel high-resolution data on civil conflict events in Sub-Saharan Africa from 1989 to 2008, this paper evaluates the relationship between sustained drought, rainfed agriculture and civil conflict violence at the subnational level. In line with the argument, areas with rainfed croplands see an increased risk of civil conflict violence following drought. There is also some support for the proposition that areas experiencing sustained droughts have a higher risk of conflict. The results are robust to a wide range of model specifications.     

The impact of Russian food security policy on the performance of the food system

Abstract

Food security has guided Russia’s food policy since 2010. The article examines the impact of food security policy on the food system. The Russian model of food security combines government intervention in the form of assistance for domestic production while simultaneously restricting market access. Food security does not appear to have a deleterious impact on the food system. We measure impact on four dimensions. Financial support for agriculture continues to increase in nominal rubles. In food production, the beef and dairy branches continue to lag, but increased grain production has made Russia a global leader in grain exports. Average per capita food consumption improved, although the poor consume much less, and the decline of the ruble affects the way Russians shop. The largest impact of food security has been on food trade. Food security policy has brought food to the forefront as an instrument of foreign policy. Food trade is politicized, witnessed by the food embargo against the West and food import bans against Turkey and Ukraine.

Informal markets and global value chains – the disembedding of Romanian dairy smallholders

The Romanian dairy-farming sector is marked by subsistence and semi-subsistence farms. Through consolidation in the retail and dairy sector, the price pressure has moved toward producers of raw milk. Through new European, national and private standards and global actors tapping into the Romanian market this development is reinforced. At the same time, the smallholders, formerly accepted to be acting on an informal level, cannot access their main distribution channels anymore. Additionally, through several legal constraints being developed since Romania’s accession to the European Union, the smallholders are neither able to issue invoices, nor to access certain subsidy programmes as they are not considered juridical persons. This article focuses on the consequences of this disembedding of farmers. The peasants are pushed toward informal activities or value chain positions, in which they do not have any bargaining power with the globally sourcing intermediaries they are supplying. The contemporary approaches of global value chains and global production networks build the theoretical framework for the study. Here it is argued that informal markets must be included into these approaches more concisely.
