North Korea on the Precipice of Famine

North Korea is on the brink of famine. The aggregate food picture appears worse than at any time since the famine of the 1990s. The margin of error between required grain and available supply is now less than 100,000 metric tons. Local food prices are skyrocketing faster than world prices. The regime has soured its aid relationships with key donors, and its control-oriented policy responses are exacerbating distress. Support for aid has been further eroded by evidence of diversion of food aid to the military and the market. Hunger-related deaths are nearly inevitable, and a dynamic is being put in place that will carry the crisis into 2009. The long-run solution to North Korea's chronic food insecurity problems is a revitalization of industry, which would allow North Korea to export industrial products, earn foreign exchange, and import bulk grains on a commercially sustainable basis. In the short run, North Korea should openly acknowledge the growing crisis and conclude negotiations with the World Food Program and other donors so that assistance can begin to flow. The United States can provide aid in ways that maximize its humanitarian impact while limiting the degree to which aid simply serves to bolster the regime. It should also exercise quiet leadership with respect to North Korean refugees.

Tiered Based Addressing in Internetwork Routing Protocols for the Future Internet

The current Internet has exhibited a remarkable sustenance to evolution and growth; however, it is facing unprecedented challenges and may not be able to continue to sustain this evolution and growth in the future because it is based on design decisions made in the 1970s when the TCP/IP concepts were developed. The research thus has provided incremental solutions to the evolving Internet to address every new vulnerabilities. As a result, the Internet has increased in complexity, which makes it hard to manage, more vulnerable to emerging threats, and more fragile in the face of new requirements. With a goal towards overcoming this situation, a clean-slate future Internet architecture design paradigm has been suggested by the research communities. This research is focused on addressing and routing for a clean-slate future Internet architecture, called the Floating Cloud Tiered (FCT) internetworking model. The major goals of this study are: (i) to address the two related problems of routing scalability and addressing, through an approach which would leverage the existing structures in the current Internet architecture, (ii) to propose a solution that is acceptable to the ISP community that supports the Internet, and lastly (iii) to provide a transition platform and mechanism which is very essential to the successful deployment of the proposed design

M3PS: End-to-End Multi-Grained Multi-Modal Attribute-Aware Product Summarization in E-commerce

Given the long textual product information and the product image, Multi-Modal Product Summarization (MMPS) aims to attract customers' interest and increase their desire to purchase by highlighting product characteristics with a short textual summary. Existing MMPS methods have achieved promising performance. Nevertheless, there still exist several problems: 1) lack end-to-end product summarization, 2) lack multi-grained multi-modal modeling, and 3) lack multi-modal attribute modeling. To address these issues, we propose an end-to-end multi-grained multi-modal attribute-aware product summarization method (M3PS) for generating high-quality product summaries in e-commerce. M3PS jointly models product attributes and generates product summaries. Meanwhile, we design several multi-grained multi-modal tasks to better guide the multi-modal learning of M3PS. Furthermore, we model product attributes based on both text and image modalities so that multi-modal product characteristics can be manifested in the generated summaries. Extensive experiments on a real large-scale Chinese e-commence dataset demonstrate that our model outperforms state-of-the-art product summarization methods w.r.t. several summarization metrics

Industries without Smokestacks

Structural transformation in Africa has become a hot topic. One of the earliest stylized facts of development economics is that low-income countries have large differences in output per worker across sectors, and movement of workers from low- to high-productivity sectors—structural transformation is a key driver of economic growth. Between 1950 and 2006, about half of the catch-up by developing countries—led by East Asia—to advanced economy productivity levels was due to rising productivity within manufacturing combined with structural transformation out of agriculture. Manufacturing has the capacity to employ large numbers of unskilled workers, is capable of large productivity gains through innovation, and entails tradeable products that permit economies of scale and specialization. But manufacturing in Africa, rather than leading growth, has typically been a lagging sector. In 2014, the average share of manufacturing in GDP in sub-Saharan Africa hovered around 10 per cent, unchanged from the 1970s, leading some observers to be pessimistic about Africa’s potential to catch the wave of sustained rapid growth and rising incomes. This book challenges that view. It argues that other activities sharing the characteristics of manufacturing—including tourism, ICT, and other services as well as food processing and horticulture—are beginning to play a role analogous to the role that manufacturing played in East Asia. This reflects not only changes in the global organization of industries since the early era of rapid East Asian growth, but also advantages unique to Africa. These ‘industries without smokestacks’ offer new opportunities for Africa to grow in coming decades

Modular wireless networks for infrastructure-challenged environments

While access to Internet and cellular connectivity is easily achieved in densely-populated areas, provisioning of communication services is much more challenging in remote rural areas. At the same time Internet access is of critical importance to residents of such rural communities. People's curiosity and realization of the opportunities provided by Internet and cellular access is the key ingredient to adoption. However, poor network performance can easily impede the process of adoption by discouraging people to access and use connectivity. With this in mind, we evaluate performance and adoption of various connectivity technologies in rural developing regions and identify avenues that need immediate attention to guarantee smoother technology adoption. In light of this analysis we propose novel system designs that meet these needs. In this thesis we focus on cellular and broadband Internet connectivity. Commercial cellular networks are highly centralized, which requires costly backhaul. This, coupled with high price for equipment, maintenance and licensing renders cellular network access commercially-infeasible in rural areas. At the same time rural cellular communications are highly local: 70% of the rural-residential calls have an originator-destination pair within the same antenna. In line with this observation we design a low-cost cellular network architecture dubbed Kwiizya, to provide local voice and text messaging services in a rural community. Where outbound connectivity is available, Kwiizya can provide global services. While commercial networks are becoming more available in rural areas they are often out of financial reach of rural residents. Furthermore, these networks typically provide only basic voice and SMS services and no mobile data. To address these challenges, our proposed work allows Kwiizya to operate in coexistence with commercial cellular networks in order to extend local coverage and provide more advanced services that are not delivered by the commercial networks. Internet connectivity in rural areas is typically provided through slow satellite links. The challenges in performance and adoption of such networks have been previously studied. We add a unique dataset and consequent analysis to this spectrum of work, which captures the upgrade of the gateway connectivity in the rural community of Macha, Zambia from a 256kbps satellite link to a more capable 2Mbps terrestrial link. We show that the improvement in performance and user experience is not necessarily proportional to the bandwidth increase. While this increase improved the network usability, it also opened opportunities for adoption of more demanding services that were previously out of reach. As a result the network performance was severely degraded over the long term. To address these challenges we employ white space communication both for connectivity to more capable remote gateways, as well as for end user connectivity. We develop VillageLink, a distributed method that optimizes channel allocation to maximize throughput and enables both remote gateway access as well as end user coverage. While VillageLink features lightweight channel probing, we also consider external sources of channel availability. We design a novel approach for estimation of channel occupancy called TxMiner, which is capable of extracting transmitter characteristics from raw spectrum measurements. We study the adoption and implications of network connectivity in rural communities. In line with the results of our analyses we design and build system architectures that are geared to meet critical needs in these communities. While the focus of analysis in this thesis is on rural sub-Saharan Africa, the proposed designs and system implementations are more general and can serve in infrastructure-challenged communities across the world

Agricultural Value Chains in India

This open access book provides a clear holistic conceptual framework of CISS-F (competitiveness, inclusiveness, sustainability, scalability and access to finance) to analyse the efficiency of value chains of high value agricultural commodities in India. It is based on the understanding that agriculture is an integrated system that connects farming with logistics, processing and marketing. Farmer’s welfare being central to any agricultural policy makes it very pertinent to study how a value chain works and can be strengthened further to realize this policy goal. This book adds value to the existing research by studying the value chains end-to-end across a wide spectrum of agricultural commodities with the holistic lens of CISS-F. It is not enough that a value chain is competitive but not inclusive or it is competitive and inclusive but not sustainable. The issue of scalability is very critical to achieve macro gains in terms of greater farmer outreach and sectoral growth. The research undertaken here brings out some very useful insights for policymaking in terms of what needs to be done better to steer the agricultural value chains towards being more competitive, inclusive, sustainable and scalable. The value chain specific research findings help draw very nuanced policy recommendations as well as present a big picture of the future direction of policy making in agriculture

Statewide Transit Intelligent Transportation Systems Deployment Plan, Rural and Small Urban Transit Systems: Final Report, October 2002

In early 2002, the Iowa Department of Transportation engaged a consultant to help develop a statewide transit ITS plan. Iowa DOT intended to provide a means for transit agencies in the state’s rural and small urban communities to utilize Intelligent Transportation Systems (ITS) applications to support and enhance transit operations. Although several of the state’s transit agencies have implemented ITS applications, most agencies continue to rely on manual procedures for operations, management, and customer service functions
