The present and future system for measuring the Atlantic meridional overturning circulation and heat transport

of the global combined atmosphere-ocean heat flux and so is important for the mean climate of the Atlantic sector of the Northern Hemisphere. This meridional heat flux is accomplished by both the Atlantic Meridional Overturning Circulation (AMOC) and by basin-wide horizontal gyre circulations. In the North Atlantic subtropical latitudes the AMOC dominates the meridional heat flux, while in subpolar latitudes and in the subtropical South Atlantic the gyre circulations are also important. Climate models suggest the AMOC will slow over the coming decades as the earth warms, causing widespread cooling in the Northern hemisphere and additional sea-level rise. Monitoring systems for selected components of the AMOC have been in place in some areas for decades, nevertheless the present observational network provides only a partial view of the AMOC, and does not unambiguously resolve the full variability of the circulation. Additional observations, building on existing measurements, are required to more completely quantify the Atlantic meridional heat transport. A basin-wide monitoring array along 26.5°N has been continuously measuring the strength and vertical structure of the AMOC and meridional heat transport since March 31, 2004. The array has demonstrated its ability to observe the AMOC variability at that latitude and also a variety of surprising variability that will require substantially longer time series to understand fully. Here we propose monitoring the Atlantic meridional heat transport throughout the Atlantic at selected critical latitudes that have already been identified as regions of interest for the study of deep water formation and the strength of the subpolar gyre, transport variability of the Deep Western Boundary Current (DWBC) as well as the upper limb of the AMOC, and inter-ocean and intrabasin exchanges with the ultimate goal of determining regional and global controls for the AMOC in the North and South Atlantic Oceans. These new arrays will continuously measure the full depth, basin-wide or choke-point circulation and heat transport at a number of latitudes, to establish the dynamics and variability at each latitude and then their meridional connectivity. Modeling studies indicate that adaptations of the 26.5°N type of array may provide successful AMOC monitoring at other latitudes. However, further analysis and the development of new technologies will be needed to optimize cost effective systems for providing long term monitoring and data recovery at climate time scales. These arrays will provide benchmark observations of the AMOC that are fundamental for assimilation, initialization, and the verification of coupled hindcast/forecast climate models

Strategic Knowledge Measurement and Management

Knowledge and intellectual capital are now recognized as vital resources for organizational survival and competitive advantage. A vast array of knowledge measures has evolved, spanning many disciplines. This chapter reviews knowledge measures focusing on groups of individuals (such as teams, business and organizations), as they reflect the stock or flow of knowledge, as well as enabling processes that enhance knowledge stocks and flows. The chapter emphasizes the importance of organizational value chains, pivotal talent pools and the link between knowledge and competitive success, in understanding the significance of today’s knowledge measures, and opportunities for future research and practice to enhance them

Organizational Capital: A New Approach to Lending in Nonprofit Affordable Housing

In spite of a diminishing supply of public resources, many nonprofit housing developers are expanding their roles and their portfolios to address an increasing need for decent affordable housing. But as nonprofit housing organizations mature, the traditional project-by-project funding system fails to support their broader development goals. This paper stresses the urgent need for equity, or "organizational capital," to help nonprofit housing organizations build their capacity and their impact. Unlike conventional financing, organizational capital is underwritten against a borrower's balance sheet, or its organizational ability to repay. Whereas project-based loans are tied to one particular project, organizational loans can be a source of liquidity whenever an organization needs it: on the front end of a deal, for general business operations or during periods of organizational expansion. Despite its many advantages, there is an extremely limited supply of organizational capital in nonprofit affordable housing. This research outlines the practical challenges to organizational investing and uncovers the underlying barriers that have prevented a nonprofit organizational capital market from emerging. These findings lead us to explore nonprofit housing organizations in a "closed system" of standardized reporting and rational decision-making. The study concludes that while a new nonprofit reporting system would greatly encourage organizational investing in housing, the private markets alone will not bring organizational lending to scale. The final sections of the paper discuss the public policy implications of a closed nonprofit capital system and highlight some innovative approaches taken by lenders to overcome the obstacles of organizational investing and advance a new model of lending in nonprofit affordable housing

International financial contagion: what do we know?

This paper attempts a synthesis of theoretical and empirical work on international financial contagion. Although a professional consensus on the appropriate definitions of contagion has yet to emerge, we document substantial research progress towards this goal. On the empirical front, determining when returns are ‘excessive’ is a pre-condition for designing effective policy response to crises. At the theoretical level, tracing the observed herding behavior to market participants’ uncertain beliefs and information asymmetries is a key element for understanding how contagious effects arise. It is argued that the recent focus on better understanding of high-frequency financial returns data and decision making at the market microstructure level are promising avenues for understanding the transmission of shocks across markets and countries

Mobility decisions of European doctoral researchers.

Student mobility remains an important component for the completion of a European Higher Education and Research Area. Two issues at the forefront are increasing student mobility within Europe as well as worries about a ‘brain drain’ of talented graduate students to North America. Unfortunately, there is still relatively little evidence and analysis available to support policy making. In this paper, using a large sample of European researchers, we analyse the decision of students where to pursue their doctoral studies: at home, in another European country or in North America. We find that students from countries with a weaker research and innovation system are more likely to seek their doctoral degree abroad, particularly within Europe. Graduate student mobility within Europe appears more driven by push factors in the home country, i.e. lack of opportunities for researchers, whereas mobility towards North America seems more driven by pull factors within the North American research and education system.

Foreign Direct Investment and Structural Reforms: Evidence from Eastern Europe and Latin America

This paper investigates the role of structural reforms ñ privatization, financial reform and trade liberalizationñ as determinants of FDI inflows based on newly constructed dataset on structural reforms for 19 Latin American and 25 Eastern European countries between 1989 and 2004. Our main finding is a strong empirical relationship from reforms to FDI, in particular, from financial liberalization and privatization. These results are robust to different measures of reforms, split samples, and potential endogeneity and omitted variables biases.http://deepblue.lib.umich.edu/bitstream/2027.42/64417/1/wp906.pd

Overcoming Roadblocks to Learning

{Excerpt} The gulf between the ideal type of a learning organization and the state of affairs in typical bilateral and multilateral development agencies remains huge. Defining roadblocks, however numerous they may be, is half the battle to removing them—it might make them part of the solution instead of part of the problem. Organizational learning is collective learning by individuals, and the fundamental phenomena of individual learning apply to organizations. However, organizational learning has distinctive characteristics concerning what is learned, how it is learned, and the adjustments needed to enhance learning. These owe to the fact that an organization is, by general definition, a collective whose individual constituents work to achieve a common goal from discrete operating and supporting units. Practices bring different perspectives and cultures to bear and shape data, information, and knowledge flows. Political considerations are the most serious impediment to becoming a learning organization. However, by understanding more fully what obstacles to learning can exist in a complex organization in a complex environment, one can circumscribe the problem space and create enabling environments for a more positive future. Such environments would facilitate self-organization, exploration of the space of possibilities, generative feedback, emergence, and coevolution.They would create an explanatory framework and facilitate action

Beyond GDP: the need for new measures of progress

This repository item contains a single issue of The Pardee Papers, a series papers that began publishing in 2008 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. The Pardee Papers series features working papers by Pardee Center Fellows and other invited authors. Papers in this series explore current and future challenges by anticipating the pathways to human progress, human development, and human well-being. This series includes papers on a wide range of topics, with a special emphasis on interdisciplinary perspectives and a development orientation.This paper is a call for better indicators of human well-being in nations around the world. We critique the inappropriate use of Gross Domestic Product (GDP) as a measure of national well-being, something for which it was never designed. We also question the idea that economic growth is always synonymous with improved well-being. Useful measures of progress and well-being must be measures of the degree to which society’s goals (i.e., to sustainably provide basic human needs for food, shelter, freedom, participation, etc.) are met, rather than measures of the mere volume of marketed economic activity, which is only one means to that end. Various alternatives and complements to GDP are discussed in terms of their motives, objectives, and limitations. Some of these are revised measures of economic activity while others measure changes in community capital—natural, social, human, and built—in an attempt to measure the extent to which development is using up the principle of community capital rather than living off its interest. We conclude that much useful work has been done; many of the alternative indicators have been used successfully in various levels of community planning. But the continued misuse of GDP as a measure of well-being necessitates an immediate, aggressive, and ongoing campaign to change the indicators that decision makers are using to guide policies and evaluate progress. We need indicators that promote truly sustainable development—development that improves the quality of human life while living within the carrying capacity of the supporting ecosystems. We end with a call for consensus on appropriate new measures of progress toward this new social goal

The Implementation of IMF Programs: A Conceptual Framework

IMF supported programs have conventionally been assessed by examining their effects on intermediate variables and final outcomes. More recently greater attention has been paid to implementation on the assumption that in order to work programs need to be implemented. Empirical studies have begun to include political economy variables in an attempt to explain implementation. They have used the concept of ‘ownership’ to provide a theoretical foundation. This paper provides an alternative conceptual framework based on the marginal benefits and costs of implementation. It goes on to discuss policies that might be expected to improve implementation based on this framework.IMF
