Television Coverage of State Government

An empirical analysis of 3,334 state and local television newsstories in 10 cities clarifies the reluctance of commercialtelevision newscasters to cover state government. Contrary towhat many television news directors assert, television's minimalattention to state government cannot be attributed to an allegednegative relationship between state government and newscastratings. Rather, it appears to stem from the high cost of obtainingfilmed coverage of state government in a timely fashion.     

Application of numerical interval analysis to obtain self-validating results for multivariate probabilities in a massively parallel environment

Conventional computations use real numbers as input and produce real numbers as results without any indication of the accuracy. Interval analysis, instead, uses interval elements throughout the computation and produces intervals as output with the guarantee that the true results are contained in them. One major use for interval analysis in statistics is to get results of high-dimensional multivariate probabilities. With the efforts to decrease the length of the intervals that contain the theoretically true answers, we can obtain results to any arbitrary accuracy, which is demonstrated by multivariate normal and multivariate t integrations. This is an advantage over the approximation methods that are currently in use. Since interval analysis is more computationally intensive than traditional computing, a MasPar parallel computer is used in this research to improve performance.     

OPTIMAL PUNISHMENT SCHEMES WITH STATE-DEPENDENT PREFERENCES

The optimal tradeoff between the certainty and severity of punishment is studied in a setting in which individuals are more sensitive to changes in certainty than severity and have state-dependent preferences—being convicted of a crime reduces utility at every wealth level. In this setting it is not optimal to set the probability of punishment at one even if it is costless to convict criminals, because reducing the certainty of punishment also reduces the probability that offenders' utility functions shift downward. The optimal level of certainty is therefore lower than that implied by prior studies based on state-independent preferences. (JEL K42, D81)     

On the Trail of a Radical Pedagogy for Social Work Education

Correspondence to Dr William De Maria, Department of Social Work and Social Policy, The University of Queensland, Brisbane 4072, Australia. Summary This article uses a general decade by decade approach to notethe emergence (1970s), decline (1980s), and re-emergence (1990s)of radical social work. An issue for this 1990s'-type radicalsocial work will become one of attending to its own teachingmission. A range of radical pedagogic principles is presented:cause-sensitive action, tailoring, contradiction-based learning,de-monopolized values, radical analysis, polemic storytelling,and centring marginality.     

ACROSS TIME AND REGIMES: 212 YEARS OF THE US‐UK REAL EXCHANGE RATE

The behavior of the US‐UK real exchange rate over the period 1794–2005 is examined. This series includes five intervals of floating nominal exchange rates and four fixed exchange rate regime periods. A consistent pattern of higher real exchange rate volatility under floating nominal rates is shown. Over time, real exchange rate movements have increasingly been driven by movements in the nominal exchange rate rather than relative prices. The persistence of the real exchange rate has been considerably higher in the postwar period. (JEL F31, N20)
