abstract Tidal strain observations from seven observatories in the continental United States have been analyzed and the results compared with the tide predicted for a radially stratified earth model. Included in the predicted tide are the effects of ocean-tide loading for all of the major oceans. We find that on average the load strains contribute 44 per cent of the total M2 tidal strain and 13 per cent of the total O1 tidal strain. The differences between the predictions of the radially stratified earth model and the observations are significant. We conclude that: (1) Love numbers deduced from most strain observations are not representative of average earth properties. (2) The phase of the areal strain is neither independent of the tidal loading nor of the local geological structure. Hence, to use such phase observations as a measure of the anelastic properties of the Earth is incorrect.

Contrary to the popular belief that women in factories are doing men's work, are the facts which are brought to light as the conditions of work when the factory system was established in the United States of America. It is incontestible that when the factory system was first established women were urged to go into factories. Men were engaged in agriculture and the "Friends of Industry" replied to those citizens who declared that manufactures would ruin agriculture that "not one fourth of the employees in manufacture were able-bodied men fit for famring." Economic gains were at first used as an arguement. Gallatin in 1831 "concluded that the surplus product obtained by the employment of owmen in a single cotton mill of 200 employees was $14,000 annually." Another writer in the "Boston Centinel" said "that machinery enables women and children who are unable to cultivate the earth to make us indepdent of foreign supplies." This entrance of women into factories was not a hardhsip because women had done much of the hard work of spinning and weaving in the homes, and later the famer's daughter had worked in the "manufcatures."

Definition of the Concept "Wilderness"The Wilderness Act of September 1964, of the United States of America, states that "... wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognised as an area where the earth and its community of life are not influenced by man and where man himself is a visitor who does not remain55 (Nash 1967). The Act also states that a wilderness "... must retain its primeval character and influence and that it must be protected and managed in such a way that it appears to have been effected primarily by the forces of nature.”

abstract In Beaumont and Berger (1975), strain observations from seven sites in the continental United States were analyzed and compared with the homogeneous tides predicted for a radially stratified earth including the effects of ocean-tide loading. In this work the effects of lateral inhomogeneities in structure are examined using two- and three-dimensional finite element models. The results demonstrate that the topographic and geologic corrections are as large as ±25 per cent of the homogeneous strain tide for some of the strainmenter sites examined. Cavity effects are normally less than 5 per cent unless the strainmeters are installed transversely in tunnels. Contour plots of the topographic effects show that they may exceed ±50 per cent of the homogeneous strain in extreme cases. It is concluded from an error analysis that a theoretical model including local perturbations due to lateral inhomogeneities as well as the load and earth tides explains the observations. However, the errors in the observations, and uncertainties in our knowledge of the deep ocean tides in particular, prevent strain observations from providing useful measures of whole earth elastic properties (Love numbers) or anelasticity. In addition to earth tides, the results demonstrate that secular strain, in situ stress, and seismic strain must all be corrected for site effects.

This article is the revised text of the first W A Wilson Memorial Lecture, given in the Playfair Library, Old College, in the University of Edinburgh, on 17 May 1995. It considers various visions of Scots law as a whole, arguing that it is now a system based as much upon case law and precedent as upon principle, and that its departure from the Civilian tradition in the nineteenth century was part of a general European trend. An additional factor shaping the attitudes of Scots lawyers from the later nineteenth century on was a tendency to see themselves as part of a larger Englishspeaking family of lawyers within the British Empire and the United States of America.

From the first days, of the first session, of the first Congress of the United States, the Senate was consumed by an issue that would do immense and lasting political harm to the sitting vice president, John Adams. The issue was a seemingly unimportant one: titles. Adams had strong opinions on what constituted a proper title for important officers of government and, either because he was unconcerned or unaware of the damage it would cause, placed himself in the middle of the brewing dispute. Adams hoped the president would be referred to as, “His highness, the President of the United States of America, and Protector of the Rights of the Same.” The suggestion enraged many, amused some, and was supported by few. He lost the fight over titles and made fast enemies with several of the Senators he was constitutionally obligated to preside over. Adams was savaged in the press, derided in the Senate and denounced by one of his oldest and closest friends. Not simply an isolated incident of political tone-deafness, this event set the stage for the campaign against Adams as a monarchist and provided further proof of his being woefully out of touch.

The armed violence of many radical Islamic movements is one of the most important means to achieve the goals and objectives of these movements. These movements have legitimized and legitimized these violent practices and constructed justification ideologies in order to justify their use for them both at home against governments or against the other Religiously, intellectually and even culturally, or abroad against countries that call them the term "unbelievers", especially the United States of America.
