Much recent analysis of British politics has assumed, explicitly or implicitly, that constituency campaigns have no impact upon an electorate that draws on an increasingly nationalized media for its information. We employ data on constituency campaign spending to challenge this interpretation. Local party campaigners are rational in their use of funds, spending most in seats where the competition is close and least where there is little hope of winning. What is more, campaign spending is clearly associated with voting, increasing support for the spending party and decreasing support for its rivals. Contrary to the accepted wisdom, local campaign spending can result in important shifts in the vote. However, local campaigning seems to be of much more value to challengers than to incumbents.

The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology (NIST) promotes the U.S. economy and public welfare by providing technical leadership for the nation's measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analyses to advance the development and productive use of information technology. ITL's responsibilities include the development of management, administrative, technical, and physical standards and guidelines for the cost-effective security and privacy of other than national security-related information in federal information systems. The Special Publication 800-series reports on ITL's research, guidelines, and outreach efforts in information system security, and its collaborative activities with industry, government, and academic organizations. Special Publication 800-137 Information Security Continuous Monitoring for Federal information Systems and Organizations ______________________________________________________________________________________________ PAGE iii AuthorityThis publication has been developed by NIST to further its statutory responsibilities under the Federal Information Security Management Act (FISMA), Public Law (P.L.) 107-347. NIST is responsible for developing information security standards and guidelines, including minimum requirements for federal information systems, but such standards and guidelines shall not apply to national security systems without the express approval of appropriate federal officials exercising policy authority over such systems. This guideline is consistent with the requirements of the Office of Management and Budget (OMB) Circular A-130, Section 8b(3), Securing Agency Information Systems, as analyzed in Circular A-130, Appendix IV: Analysis of Key Sections. Supplemental information is provided in Circular A-130, Appendix III.Nothing in this publication should be taken to contradict the standards and guidelines made mandatory and binding on federal agencies by the Secretary of Commerce under statutory authority. Nor should these guidelines be interpreted as altering or superseding the existing authorities of the Secretary of Commerce, Director of the OMB, or any other federal official.

Contrast injection rate and timing of measurements significantly influence the optimal L-S threshold for diagnosing fatty liver. This limits the clinical usefulness of such measurements.

Open political discussion between citizens is a cornerstone of democratic theory and contextual accounts of political behaviour. It provides both a means through which individuals can discover what their peers think and a forum within which they can rationalize, explain and perhaps modify their own opinions. Much previous research has focused on the potential of political conversation as a means of influencing others and of converting holders of minority views to the opinions of the majority. However, theoretical accounts of political conversation also stress its potential impact on more systemic attitudes towards democracy, including the development of tolerance for divergent views and lifestyles. The article provides an evaluation of these potential effects in the context of recent British politics.

A number of recent studies have presented classifications of geographical data using numerical methods which have been adopted from other scientific disciplines. Before a classification can begin, however, the investigator must make three sets of decisions regarding the exact process to be employed. Some of his choices are predetermined by the nature of the data and the research design but others may be taken on subjective grounds alone. Computational examples demonstrate the effects of third stage choices on the results of two classifications. The results are analogous to the general geographical problem of regional cores and zones of transition. All methods extract virtually the same core but choice can govern the classification of units within the zone of transition. Classification is thus basically a subjective process, despite the apparent objectivity of the methods employed.
