The new Parliament will be asked at some point to make critical decisions about the BBC's future at a time when it is facing full‐frontal assaults from competitors who view the BBC as a major barrier to their own advancement. Whether it be newspaper groups seeking to monetise their online activities, commercial children's channels, terrestrial competitors or the owners of music radio stations, media conglomerates rail against the BBC's size and public funding with increasing regularity. Our aim is to remind our legislators of the vital contribution this institution makes to British life: from a journalism inscribed with values of fairness, integrity and impartiality—and valued throughout the world for its professional engagement with foreign affairs—to its creative commitment to British story‐telling, music, comedy, arts and children's programmes, the BBC's contribution to our democratic and cultural welfare is immense. It is a beacon for Britain, which provides social glue for its citizens at a time of fragmenting audiences and identities, within a uniquely non‐commercial space, accountable to both Parliament and its licence payers. It may distort the market, much as the National Health Service distorts the market for health care, but is held in high esteem by the British public and is admired throughout the world. This article explains why the BBC is a national treasure that underpins our creative economy as well as our cultural vitality, and argues that it must be protected from those who argue self‐interestedly for its diminution.  相似文献

This article examines issues in the presentation of factual evidence in school finance litigation. It focuses specifically on statistical measures of dispersion which have been included in Berne and Steifel's framework for analyzing distributional equity. It identifies the methodological issues that must be recognized when these measures are used in litigation, and the properties/characteristics of individual measures that may lead courts to different determinations about "equity" in school finance.  相似文献

In 2004 President Bush was elected more decisively than in 2000, but he would have lost if Ohio had voted for John Kerry. Turnout in a polarised electorate was the highest since the 1960s. Bush saw his party increase its existing majorities in both houses of Congress - the first Republican candidate to do so since 1924. The Republicans benefited from political trends in the South, international developments and the impact of social issues. Gains by Bush at the time of the national conventions were reduced by Kerry's strong showing in the televised debates. In the end, Americans were unwilling to eject their commander-in-chief during the wars on terror and in Iraq. While the Republicans have been advancing in national politics since the 1960s, it is unclear whether 2004 was a realigning election. There was not a realignment in the classic way that it occurred in 1932.  相似文献

Research Summary Despite frequent calls for national data on police use of force, the literature is dominated by unrepresentative samples from a small number of primarily urban jurisdictions, inconsistent definitions of force, and differing universes for the computation of rates. Among 36 publications that report on the amount of nonlethal force used by the police, rates vary from 0.1% to 31.8%. To improve our ability to estimate the amount of nonlethal force in the United States, we employ data from two sources: the Police‐Public Contact Survey (PPCS) and the Survey of Inmates in Local Jails (SILJ). Using comparable measures from these surveys, we estimate that the police use or threaten to use force in 1.7% of all contacts and in 20.0% of all arrests. The PPCS accounts for 87% of the total force incidents derived from both surveys. Males, youths, and racial minorities report greater rates of police use of force, but multivariate models highlight the role of potentially provoking behaviors on the likelihood and severity of force. Policy Implications Improved estimates from the combined PPCS‐SILJ samples support the proposition that police use force infrequently and at the lower end of the severity scale. Reported amounts of force vary based on respondent race, sex, and age, but greater variation in police use of force is explained by suspect behavior. The combined PPCS‐SILJ sample provides a more representative basis for estimating the rate and correlates of nonlethal force. State and local estimates from less representative samples can be interpreted in light of these findings. National estimates could be improved by devoting sufficient resources to support the collection of agency records of both lethal and nonlethal force.  相似文献

This paper focuses on the characterization of the criminal careers of youthful offenders. It was found that these criminal careers could be modeled with parameters rejecting constant individual rates of offending and constant probability of career termination; population heterogeneity could be adequately represented by two distinct groups—designated here as "frequents" and occasionals." These parameters were estimated for the multiple offenders in a London cohort studied from their first convictions until age 25. In that cohort, the frequents were estimated to have an annual conviction rate of 1.14 convictions per year (constant with age) and a probability of career termination of .10 following each conviction; the occasionals had an annual conviction rate of .41 and termination probability of .33 following each conviction; the frequents were estimated to comprise 43% of the population, and the occasionals the others 57%. While this parsimonious model structure was adequate for the London cohort, it must still be tested with other offender populations.  相似文献
