The governance of the IMF: how a dual board structure could raise the effectiveness and legitimacy of a key global institution
The International Monetary Fund is currently engaged in a reform process to update its activities to the challenges of economic globalisation and establish it firmly as the central institution for international monetary cooperation. Yet, the current reforms may miss this aim because they do not foresee adjusting IMF governance so as to allow the Executive Board to become a forum for true international economic dialogue. Without such a change in governance, however, such economic dialogue is likely to continue moving outside the IMF, and spread in fora such as the G7, G20 or others that do not have universal status.
This paper lays out a new proposal to adjust governance to make the IMF more effective in this area. It proposes to create a new smaller Board to deal with global economic issues of a systemic nature, and enlarge the current Board to make more room for developing countries, focusing it on country-related and technical matters, including bilateral surveillance and structural adjustment lending.
The implementation of a dual Board structure is obviously challenging from an institutional point of view, and the paper discusses these challenges in detail. Yet, it would allow the IMF to be more effective and carry greater legitimacy vis-Ă -vis developing economies and at the same time play a more central role in international economic consultation and cooperation that in recent years has increasingly drifted towards the G-groups such as the G7, G20, G24 and other fora

PsRBR1 encodes a pea retinoblastoma-related protein that is phosphorylated in axillary buds during dormancy-to-growth transition
In intact plants, cells in axillary buds are arrested at the G1 phase of the cell cycle during dormancy. In mammalian cells, the cell cycle is suppressed at the G1 phase by the activities of retinoblastoma tumor suppressor gene (RB) family proteins, depending on their phosphorylation state. Here, we report the isolation of a pea cDNA clone encoding an RB-related protein (PsRBR1, Accession No. AB012024) with a high degree of amino acid conservation in comparison with RB family proteins. PsRBR1 protein was detected as two polypeptides using an anti-PsRBR1 antibody in dormant axillary buds, whereas it was detected as three polypeptides, which were the same two polypeptides and another larger polypeptide 2 h after terminal decapitation. Both in vitro-synthesized PsPRB1 protein and lambda protein phosphatase-treated PsRBR1 protein corresponded to the smallest polypeptide detected by anti-PsRBR1 antibody, suggesting that the three polypeptides correspond to non-phosphorylated form of PsRBR1 protein, and lower- and higher-molecular mass forms of phosphorylated PsRBR1 protein. Furthermore, in vivo labeling with [32P]-inorganic phosphate indicated that PsRBR1 protein was more phosphorylated before mRNA accumulation of cell cycle regulatory genes such as PCNA. Together these findings suggest that dormancy-to-growth transition in pea axillary buds is regulated by molecular mechanisms of cell cycle control similar to those in mammals, and that the PsRBR1 protein has an important role in suppressing the cell cycle during dormancy in axillary buds
Role of growth regulators in the bean hypocotyl hook opening response
The opening of the hypocotyl hook in bean seedlings is due to a rapid elongation of cells on the inner side of the hook elbow. Red light promotes hook opening by inducing this cell elongation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47488/1/425_2004_Article_BF00389364.pd
Ethylene and carbon dioxide as mediators in the response of the bean hypocotyl hook to light and auxins
Ethylene inhibits hook opening in the bean hypocotyl and at high concentrations induces closure of the hook. Indoleacetic acid and 2,4-dichlorophenoxyacetic acid, whose inhibitory effect on hook opening resembles that of ethylene, stimulate ethylene production from the hook tissue, and this ethylene production is physiologically active in inhibiting hook opening. It is concluded that the inhibition of opening by auxin is due at least in a major part to auxin-induced ethylene production by the hook tissue.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47489/1/425_2004_Article_BF00389365.pd
Respiration and oxygen transport in soybean nodules
The respiration rate of individual soybean ( Glycine max Merr.) nodules was measured as a function of pO 2 and temperature. At 23°, as the pO 2 was increased from 0.1 to 0.9 atm, there was a linear increase in respiration rate. At 13°, similar results were obtained, except that there was an abrupt saturation of respiration at approximately 0.5 atm pO 2 . When measurements were made on the same nodule, the rate of increase in respiration with pO 2 was the same at 13° and 23°. Additional results were that 5% CO in the gas phase had no effect on respiration, except for a small decrease in the pO 2 at which respiration became saturated. Also, nodules still attached to the soybean root displayed the same respiratory behavior as detached nodules. A model for oxygen transport in the nodule is presented which explains these results quantitatively. The essence of the model is that the respiration rate of the central tissue of the nodule is almost entirely determined by the rate of oxygen diffusion to the respiratory enzymes. Evidence is given that the nodule cortex is the site of almost all of the resistance to oxygen diffusion within the nodule.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47460/1/425_2004_Article_BF00388605.pd
