On The Financial Characteristics Of Firms That Have Achieved The Highest Levels Of Accuracy In Earnings Predictability

The value of a company is said to be a function of the future earnings or cash flows the company will produce discounted at a rate commensurate with risks associated with those cash flows. The subject of earnings predictability or the lack of reliable forecasts has been of interest to academic researchers and financial managers for years. Value Line publishes weekly, a ranking of the reliability of earnings predictions for every firm in their database. The higher the Value Line ranking for earnings predictability, the more likely they would recommend it as a safe investment. Earnings predictability is then, simply one of their important measures of potential value and safety.  The purpose of this study is to provide a financial analysis of those firms described by Value Line as having the most reliable levels of earnings predictability in their database. Specifically, the analysis will test for significant differences in the financial profiles of those firms that achieved the highest Value Line ratings for earnings predictability, and companies selected at random from the same industries.  A unique financial profile is estab­lished for the highest rated group, and it is suggested that the profile may be used to identify firms that because of their financial nature are capable of producing the most accurate sales forecasts, and earnings predictability. As in previous studies of this nature Multiple Discriminant Analysis is used.&nbsp

Enhancing Food Security in an Era of Global Climate Change: An Executive Session on Grand Challenges of the Sustainability Transition

The goal of the workshop was to build a more strategic and integrated perspective on the threats and opportunities latent in the food / climate issue, and to discuss the hard challenges of moving forward toward common goals in a private, off-the-record setting. An executive session convened by the John F. Kennedy School of Government at Harvard University and the Venice International University on June 6-9, 2010, attracted more than 25 of the world's leading experts from the fields of policy, science, and business to San Servolo Island for an intensive three- day session (see text for a list of the participants). The discussions were off-the-record, with each participant present in his or her own capacity, rather than representing an organization. The session was one in a series on Grand Challenges of the Sustainability Transition organized by the Sustainability Science Program at Harvard University with the generous support of the Italy’s Ministry for Environment, Land and Sea. This particular session was held in cooperation with the new Mega Program on Climate Change, Agriculture and Food Security being developed by the Consultative Group on International Agricultural Research (CGIAR) and the Earth System Science Partnership. This summary report of the session is our synthesis of the main points and arguments that emerged from the discussions. It does not represent a consensus document, since no effort was made at the session to arrive at a single consensus view. Rather, we report here on what we heard to be the major themes discussed at the session. Any errors or misrepresentations remain solely our responsibility

Boundary Work for Sustainable Development: Natural Resource Management at the Consultative Group on International Agricultural Research (CGIAR)

Previous research on the determinants of effectiveness in knowledge systems seeking to support sustainable development has highlighted the importance of “boundary work” through which research communities organize their relations with new science, other sources of knowledge, and the worlds of action and policymaking. A growing body of scholarship postulates specific attributes of boundary work that promote used and useful research. These propositions, however, are largely based on the experience of a few industrialized countries. We report here on an effort to evaluate their relevance for efforts to harness science in support of sustainability in the developing world. We carried out a multicountry comparative analysis of natural resource management programs conducted under the auspices of the Consultative Group on International Agricultural Research. We discovered six distinctive kinds of boundary work contributing to the successes of those programs—a greater variety than has been documented in previous studies. We argue that these different kinds of boundary work can be understood as a dual response to the different uses for which the results of specific research programs are intended, and the different sources of knowledge drawn on by those programs. We show that these distinctive kinds of boundary work require distinctive strategies to organize them effectively. Especially important are arrangements regarding participation of stakeholders, accountability in governance, and the use of “boundary objects.” We conclude that improving the ability of research programs to produce useful knowledge for sustainable development will require both greater and differentiated support for multiple forms of boundary work

Toward a General Theory of Boundary Work: Insights from the CGIAR’s Natural Resource Management Programs

Linking International Agricultural Research Knowledge with Action for Sustainable Development

We applied an innovation framework to sustainable livestock development research projects in Africa and Asia. The focus of these projects ranged from pastoral systems to poverty and ecosystems services mapping to market access by the poor to fodder and natural resource management to livestock parasite drug resistance. We found that these projects closed gaps between knowledge and action by combining different kinds of knowledge, learning, and boundary spanning approaches; by providing all partners with the same opportunities; and by building the capacity of all partners to innovate and communicate

Parasite maturation and host serum iron influence the labile iron pool of erythrocyte stage Plasmodium falciparum

Iron is a critical and tightly regulated nutrient for both the malaria parasite and its human host. The importance of the relationship between host iron and the parasite has been underscored recently by studies showing that host iron supplementation may increase the risk of falciparum malaria. It is unclear what host iron sources the parasite is able to access. We developed a flow cytometry-based method for measuring the labile iron pool (LIP) of parasitized erythrocytes using the nucleic acid dye STYO 61 and the iron sensitive dye, calcein acetoxymethyl ester (CA-AM). This new approach enabled us to measure the LIP of P. falciparum through the course of its erythrocytic life cycle and in response to the addition of host serum iron sources. We found that the LIP increases as the malaria parasite develops from early ring to late schizont stage, and that the addition of either transferrin or ferric citrate to culture media increases the LIP of trophozoites. Our method for detecting the LIP within malaria parasitized RBCs provides evidence that the parasite is able to access serum iron sources as part of the host vs. parasite arms race for iron
