As expected from an IPHS conference, the majority of the 15 contributionsare firmly rooted in the discipline of planning history, though most are concernedto link past, present and future, and some are predominantly about the contemporarycity. The geographical focus is wide-ranging, including chapters on LatinAmerica and South America as well as Europe and the US. Cultural geographerswill no doubt be attracted by the intriguing title. They might, however, bedisappointed by what they find inside the covers, especially as the combinationof `cul- ture', `urbanism' and `planning' is used as a loose umbrella fordisparate chapters rather than a starting point for analysis. The editors'introductory chapter has only a brief discussion of the three concepts, butit makes clear that their focus is planning for the cultural economy ratherthan the ways in which culture gets into planning. The presence of the terms`urban- ism' and `planning' in the title is seen as little more than an attempt`to delimit a more com- prehensive and fluid area of problems, than that whicheach term evokes on its own' (p. xvi). Many of the chapters take a wider viewof the culture–planning relationship, but the impli- cations tend tobe implicit rather than explicit. The chapters that rise to the challengeof link- ing culture and planning reflect the concern with planning for culturein its narrowest sense.522Thestrength of the book lies in the intriguing stories and thick descriptionsof the chap- ters, such as Margarita Gutman's discussion of the metropolis-likefuture visions for Buenos Aires from the 1920's conceptualization and widerreflection. Moreover, Steven Ward's insight- ful concluding chapter on theorigins and dissemination of the `Baltimore model' of water- front regenerationshows what might have been achieved by the other chapters in terms of linkingcase studies to broader conceptual concerns. Ultimately, however, too manycontribu- tions feel like they are conference papers rather than fully workedbook chapters. Culture, urbanism and planning will probably have limited appealfor most cultural geographers

A tighter bound on the area occupied by a fractal image

We derive a bounding circle for a fractal image specified by an iterated function system. The radius of the bounding circle is smaller than those from previously published material. The bounding circle is important in fractal design and plotting software as it enables a fractal image to be scaled correctly to fit the screen of a digital computer

Shuttle Entry Air Data System (SEADS) hardware development. Volume 2: History

Hardware development of the Shuttle Entry Air Data System (SEADS) is described. The system consists of an array of fourteen pressure ports, installed in an Orbiter nose cap, which, when coupled with existing fuselage mounted static pressure ports permits computation of entry flight parameters. Elements of the system that are described include the following: (1) penetration assemblies to place pressure port openings at the surface of the nose cap; (2) pressure tubes to transmit the surface pressure to transducers; (3) support posts or manifolds to provide support for, and reduce the length of, the individual pressure tubes; (4) insulation for the manifolds; and (5) a SEADS nose cap. Design, analyses, and tests to develop and certify design for flight are described. Specific tests included plasma arc exposure, radiant thermal, vibration, and structural. Volume one summarizes highlights of the program, particularly as they relate to the final design of SEADS. Volume two summarizes all of the Vought responsible activities in essentially a chronological order

Assessment and Management of Suicide Risk in Primary Care

Abstract Background Risk assessment and management of suicidal patients is emphasized as a key component of care in specialist mental health services, but these issues are relatively unexplored in primary care services. Aim To examine risk assessment and management in primary and secondary care in a clinical sample of individuals who were in contact with mental health services and died by suicide. Method Data collection from clinical proformas, case records, and semi-structured face–to-face interviews with general practitioners. Results Primary and secondary care data was available for 198 of the 336 cases (59%). The overall agreement in the rating of risk between services was poor (overall kappa = 0.127; p = 0.10). Depression, care setting (post discharge), suicidal ideation at last contact and a history of self-harm were associated with a rating of higher risk. Suicide prevention policies were available in 25% of primary care practices and 33% of staff received training in suicide risk assessments. Conclusion Risk is difficult to predict, but the variation in risk assessment between professional groups may reflect poor communication. Further research is required to understand this. There appears to be a relative lack of suicide risk assessment training in primary care

Generalized sampling interpolation of noisy gravity/gravity gradient data

The generalized sampling expansion (GSE) has been shown as a method for successfully interpolating combined gravity and gravity gradient data sets when the data are undersampled. The presence of noise on data sets renders such interpolation more difficult and many applications (known as expansions) of the GSE can be shown to intolerably amplify noise. However, many key expansions can be shown to successfully interpolate noisy data and even, given limited gradient error and sufficiently narrow line-spacing, reduce noise. These results can be shown to hold for both random noise and along-line correlated (levelling error type) noise. Unfortunately, the only expansion capable of interpolating a data set sampled at 3× conventional line-spacing, the Three-rectangle expansion, has a poor noise response and always acts to amplify data error. The GSE method bares up well against other methods of gradient enhanced interpolation; in numerical tests several expansions for the gravity field produce less noisy output than any of the pseudo-line, gradient enhanced minimum curvature or gradient enhanced Akima spline methods. Despite edge effects and using only gradient data with no gravity component, the GSE applied to real undersampled survey data bares up well against conventional interpolation, reducing noise where the data are clearly undersample
