On the new Cambridge school
A simple macroeconomic model may be used to enunciate some of the key propositions of the "New Cambridge School" (NCS), and especially to identify and emphasize their breaks with Keynes' vision of the economic system. The penultimate section of the paper contains a simplified version of the NCS view of the relationship between the budget deficit and the trade deficit. For ease of exposition I deal only with real magnitudes and neglect time lags throughout.
Godley Moves in Mysterious Ways: The Craft of Economic Judgment in Post-war Britain
Economists are not memorialized in monuments. Wynne Godley is the exception, his likeness is cast in bronze upon Coventry Cathedral as archangel Michael (‘St Michael’s Victory over the Devil’, 1958) in a sculpture by his father-in-law Jacob Epstein. On his passing, Godley was remembered in obituaries in the major British broadsheets, that recalled his dotted career, his engagement with the arts, his grace as a host and his tragic family history.1 At the venerable age of 75, Godley penned an essay to the London Review of Books on his battles, four decades earlier, with an abusive psychoanalyst (Godley 2001). If one were to write Godley’s biography (and I know of no such plans) the defining features of his character would be taken from this autobiographical account: a search for his true voice, and as he took many public roles, a nagging fear that he might disappoint such responsibilities. The tensions that made up the intimate structures of his psychoanalytic self help also to describe his approach to economics: an anxious affirmation of voice and judgment.
Comparison between Two Chemicals for Reducing Scale Formation in Reverse Osmosis Systems
In this present research was transacted with the calcium carbonate scale inhibition on the membrane surface of the reverse osmosis desalination system. Influence of changing feed solution flow rate (10-25)l/h, pH of the feed solution (6-10) on the recovery ,penetrate flow rate and total dissolved solid in (RO) system by using solution of calcium carbonate as feed solution was investigated, furthermore the effect of adding two types of scale inhibitor ,zinc chloride and polyamino polyether methylene phosphonate with difference concentration (2-8)mg/l for zinc chloride and (8-15) mg/l for polyamino polyether methylene phosphonate was calculated. The results showed that the permeate rate increases as the feed flow rate augmentation ,while it reducing with time, the total dissolved solids decreases as the feed flow rate increases while it increases with time and recovery rate decreases as the feed flow rate increases and it also decreases with time. It was concluded that the permeate rate decreases as the feed solution pH value increases and it cause high scale forming thus decrease the permeate TDS.By adding the scale inhibitor, it was found that the permeate rate and recovery rates increases as the concentration of inhibitor increases while the total dissolved solids decreases in the permeate with increasing the concentration of both inhibitors .It was discovered that Polyamino polyether methylene phosphonate more sturdy than zinc chloride as scale inhibitor for reverse osmosis desalination system in all concentrations was studied in this article.
