A continued fraction generator for smooth pulse sequences

Digital circuit produces rational output pulse rate at fraction of continuous input pulse rate. Output pulses have average rate with least possible deviation from absolute correct time spacing. Circuit uses include frequency synthesizing, fraction generation, and approximation of irrational sequences

Renaissance attachment to things: material culture in last wills and testaments

Over the past decade ‘material culture’ has become a sub-discipline of Italian Renaissance studies. This literature, however, has focused on the rich and their objects preserved in museums or reflected in paintings. In addition, the period 1300 to 1600 has been treated without attention to changes in the relationship between people and possessions. The article turns to last wills and testaments, which survive in great numbers and sink deep roots through late medieval and Renaissance cities and their hinterlands. They reveal aspirations and anxieties about things from post-mortem repairs to farm houses to pillows of monk's wool. These aspirations changed fundamentally after the Black Death. Earlier, during the ‘commercial revolution’, ordinary merchants, artisans, and peasants on their deathbeds practised what the mendicants preached: stripping themselves of their possessions, they converted their estates to coin to be scattered among pious and non-pious beneficiaries. After the Black Death, testators began to reverse tack, devising ever more complex legal strategies to govern the future flow of their goods. This work of the dead had larger economic consequences. By encouraging the liquidation of estates, the earlier mendicant ideology quickened the velocity of exchange, while the early Renaissance attachment to things did the opposite

A New Scale to Measure War Attitudes: Construction and Predictors

Attitudes people have toward war in general have been of recent interest due to the war on terrorism and the war in Iraq. The purpose of this research was to develop a scale to measure war attitudes and to investigate factors that may influence these attitudes. In the first study, a scale was developed that measured war attitudes. Three factors emerging from the War Attitude Scale were labeled ethics of war, support for war, and affect about war. Patriotism-nationalism, authoritarianism, social criticism, belief in war outcomes, support of the president, and gender were found to be significant predictors of war attitudes. In the second study, the scale was administered to a community sample. A confirmatory factor analysis was conducted with three similar factors emerging. Additionally, the community sample results allowed further generalization of the findings. Implications for the construction of the War Attitude Scale and its predictors are discussed
