中国"三农"问题的由来和发展

中国在改革开放过程中出现的特有的城乡关系和特有的城乡发展路径,产生了中国特有的"三农"问题的理论.这个理论的形成和运用,对于深入认识我国的基本国情、用以指导社会主义现代化建设的实践和对其他国家的问题进行研究,都是很有意义的.我国"三农"问题总的情况是农业问题已经基本上得到了解决,但农民问题和农村问题还很严重,主要根源还在于计划经济体制下所形成的一套农村、农业政策还没有得到根本转变.解决农民问题和农村问题,要继续深化农村体制改革,下决心改革户籍制度,改革现有的土地承包制度,改革现有的国民收入分配格局和乡镇现有的政权体制包括财政体制.     

Identification of Green Pigment Used in Persian Wall Paintings (ad 1501–1736) Using PLM,FT–IR,SEM/EDX and GC–MS Techniques

The technique of oil painting was introduced to Iran via a cultural exchange with Europe in the Safavid period (ad 1501–1736). Since the first attempt at scientific conservation of wall paintings in Iran in the 1960s, the nature of green pigment used in Persian wall paintings has not been clear, although work on contemporary miniature paintings has identified malachite and verdigris. PLM, FT–IR, SEM/EDX, GC–MS and the study of contemporary historical treatises of the Safavid period were the main tools used in the present study to identify the green pigments in Persian (oil‐based) wall paintings. Eight samples taken from the two famous Safavid buildings, Chehel Sotoon Palace and the Sukias House in Isfahan, were analysed. Here, the identification of copper‐based pigment and of verdigris in oil as oleate amends the existing knowledge of the green pigment used in these paintings. It also suggests that oleate was introduced to Persian artists via the European influence on Persian painting as a result of cultural exchange in the Safavid period, when the technique of Persian painting changed from tempera to oil painting. However, as verdigris in oil and resin can appear as oleate over time, it is unknown whether the Persian artists did this deliberately or accidentally.     

Disparity Despite Diversity: Social Injustice in New York City's Urban Agriculture System

Many studies have documented the benefits of urban agriculture, including increased food access, job creation, educational opportunities, and green space. A focus on its social benefits has fed an association of urban agriculture with social justice, yet there is a distinction between alleviating symptoms of injustice (such as disparate access to food or environmental amenities) and disrupting structures that underlie them. Despite its positive impacts, urban agriculture systems may reinforce inequities that practitioners and supporters aim to address. This paper reports findings from a 2‐year study of urban agriculture in New York City, which found race‐ and class‐based disparities among practitioners citywide. Using the lens of critical race theory, it argues that a failure to examine urban agriculture's role in either supporting or dismantling unjust structures may perpetuate an inequitable system. The paper concludes with recommendations for urban agriculture supporters and scholars to help advance social justice at structural levels.     

Exploring motivation crowding around farmer incentives for riparian management in Nova Scotia

Incentive programs to encourage landowners to protect habitat should be carefully designed to avoid motivation crowding: basically, replacing intrinsic reasons such as a land ethic with extrinsic ones like payments. Little research on motivation crowding tests real programs, and no such work has been done in Canada. We surveyed farmers in Nova Scotia in 2017 to explore whether participation in a new incentive program called Wood Turtle Strides, or knowledge about a similar incentive program potentially available in the future, would alter reported motivations to use riparian setbacks and buffers. Motivations to use setbacks or buffers were heavily intrinsic across all four survey cohorts: wildlife stewardship and sacrifice motivated actions more than social pressures. We were not able to statistically test for motivational crowding due to low program uptake and thus post-program survey responses, but there was no evidence of second-hand crowding: farmers being motivated by hearing about a program in an adjacent jurisdiction. Findings point to the significance of wildlife stewardship for many farmers, and persistent resistance to conservation among others, as well as a risk of low additionality. More post-program research is necessary to fully understand the program's net impact on motivations and conservation.

On the Origin of the Green Colour of Archaeological Bone Artefacts of the Gallo‐Roman Period

Recent findings in the city of Reims have lead to the discovery of manufactured bone objects coloured in green throughout their entire volume. In order to discover the intentional nature of the colouration and to propose a colouration mechanism, modern ox bones have been coloured in the laboratory. Bones with a hue similar to that of the archaeological artefacts have been obtained by boiling in an acidic brine in a copper vessel. A combination of infrared spectroscopy, X‐ray diffraction and transmission electron microscope observations did not reveal the speciation of copper, but allowed us to validate the colouration process and to discuss the intentional origin of the colouration.     

Subsidizing Migration? Mexican Agricultural Policies and Migration to the United States

Migration theories often ignore the role that states play in stimulating migration through public assistance policies. Using the case of Mexico, this article explores the role of the state as a migrant‐producing actor by examining the relationship between migration and social assistance policies in the form of monetary cash transfers. It argues that direct, unconditional cash transfers, like those provided by agricultural programs such as Procampo, rather than providing the incentives needed to retain individuals in their home country, may instead be providing the resources needed to migrate, particularly if the amount of the transfer is insufficient to spur investment. Instead of discouraging migration by enhancing economic opportunities and reducing poverty, such policies can actually make it easier and more appealing for its beneficiaries to migrate.     

The historical roots of differing rural gender orders in Norway and Sweden

Offering a systematic comparison of the history of the differing rural gender orders that have developed in Norway and Sweden since 1750, this article considers the complex interconnections between gender and capitalist relations. It begins by highlighting the contrasts between these two Scandinavian countries’ settlement patterns, agricultural structures and rural gender orders, in spite of the similarities in their environments, social-democratic policies and commitments to gender equality. Within a theoretical framework focused on the persistence of simple commodity production by farming families within capitalist economies, it considers the gender division of labour, commodity systems, and laws of succession and inheritance as they bear upon the positions of farm women in Norway and Sweden. Tracing the development of stratification in the countryside and the history of farmers’ political activism at the national level illuminates the salient differences between these two countries’ histories from the early 19th through the late 20th centuries. This comparison demonstrates that gender as well as the mobilization of rural citizens shaped the transition to capitalism and that, in turn, agricultural and settlement policies reshaped rural gender relations.     

Sexualized violence and the gendered commodification of the animal body in Pacific Northwest US dairy production

This article draws on a case study of bovine life in the US dairy industry to observe the power relations and violent networks of commodification involved. I use the terms gendered commodification and sexualized violence to understand the lives of animals in the industry and the discourses that are employed to reproduce its practices. Focusing on sex and gender, concepts which have long been classic in feminist geography, this article explores the sexually violent commodification of both female and male animals in dairy production. In addition to the ways in which both are exploited for their productive and reproductive capacities, male animals are also discursively conceptualized as perpetrators of the violence against the females. This article engages with geographies of the body and animal geographies in order to extend geographies of the body to other-than-human bodies and in order to feature the body more prevalently in animal geographies. This attention to the animal body ultimately reveals the pervasiveness of sexual violence and the consequences of gendered commodification for both nonhuman and human others.
