Over the past few decades, Peru has shown significant increases in enrolment in basic education, which continues to rise. However, on average educational performance,while increasing, is still low (compared to national or international benchmarks). Furthermore, there are significant gaps in achievement between groups of students, that seem to remain stable or even increase over time (for example urban over rural). In this chapter we present evidence to show that there is a strong association among the individual and familycharacteristics of students, their educational opportunities at school, and the outcomes of their education, so that they reinforce one another. Thus the challenge for the educational system in Peru is to break this perverse triangle, so that the average outcomes will increase at the same time that inequities associated with socioeconomic characteristics diminish.

Tropical deforestation is responsible for 15-20% of total man-made emissions of greenhouse gases. In December 2007, at the international conference of Bali, the United Nations acknowledged that a viable solution to climate change must include a mechanism to limit deforestation and forest degradation. Today, the most widely used economic tool to reduce emissions is carbon markets: caps on emitters, and trade allowed between emitters and reducers, drive a price signal on carbon and provide incentives to control emissions. This report examines the different possibilities to broaden the range of this tool so that it helps reduce emissions from deforestation. The three main possibilities presented are a tax-based fund, the use of auctions revenues, and the issuance of tradable credits. The report does not discuss other instruments unrelated to carbon-related payments. We first summarize existing information on the causes of deforestation, and the impact forest loss has on the global climate. To the contrary of a commonly held view, we find that farmers, more than loggers, are driving deforestation. Some, mostly in Africa, cut the forest to grow staple crops, while others, especially in South America, do so in response to the increasing demand for commercial crops and cattle. Building on this analysis, we describe the different possibilities to link carbon markets to the fight against deforestation. In the latter case of the issuance of tradable credits, we find that while carbon markets could substantially increase the amount of funding available to develop projects and programs that reduce deforestation, demand for carbon credits must keep up with this potential new source of supply, probably around one billion ton of CO2 per year. As an analysis conducted by EDF shows, the emission caps currently advocated by the European Commission for Europe and by the Lieberman-Warner bill for the US would create enough demand to generate a price signal around 20 €/tCO2. Other solutions such as reserve prices in auctions or credits banking have been put forward to mitigate the risk of too many deforestation credits flooding carbon markets. In any case, reducing deforestation and maintaining a high price signal on carbon markets are like conjoined twins in the fight against climate change. Their link can be both a source of strength and vulnerability, but they eventually are both essential to achieve the ultimate goal of stabilizing the climate.

The interaction between fibronectin and C1q was studied in the presence of normal human plasma and rheumatoid synovial fluid by solid phase binding assay. Fibronectin-C1q binding occurred in the presence of rheumatoid synovial fluid but not in the presence of normal plasma. Binding was strongest at 4 degrees C and in the presence of EDTA. Fibronectin-C1q binding could be induced in the presence of normal plasma by hypotonicity, augmentation of the concentration of solution-phase fibronectin or by the addition of heat-aggregated IgG. The C1q present in rheumatoid synovial fluid bound to both aminoterminal collagen-binding and carboxyterminal noncollagen binding fibronectin fragments although binding to the aminoterminal fragment was stronger. The interaction between fibronectin and C1q in rheumatoid synovial fluid may modulate immune-complex deposition and complement activation in the inflamed joint.
