Sex Offenses: The British Experience
Swedish architectural modernism is intimately tied to thedevelopment of the welfare state, where the roles and work ofarchitects largely followed governmental building policies. Thepolitical and economical crisis of the late 1960s and 1970swas particularly devastating for Swedish architecture as theshortcomings of the welfare state were partly blamed on thearchitecture profession. This paper is a study of the NationalBoard of Public Building (KBS)âa Governmental agencyin charge of providing office space for State institutionsâand its ambition to rationalise its organisation and buildingconstruction. KBSâ developments during the late 1960sand early 1970s redefined the role of the architect throughquestioning the organisation of the building industry, theprocess of design, and the role of the State in building. In1967, a larger reorganisation of KBS was prompted by theGovernmentâs implementation of a new budgeting systemcalled program budgeting, which besides being a financialsteering mechanism also served as a planning system inwhich the strict cost-effectiveness of the agencies programswere measured. KBSâs response to the enforced changesresulted in the launching of an official architectural theory in1968, the so-called âKBS structure philosophy,â that at largewas a pragmatic structuralist approach to building. It wasdeveloped through rigorous investigations during the 1960s andsubsequently realized, in assimilation with program budgeting,with great force and conviction. The analysis suggests thatKBS, and its consultant architects, responded to the Stateâsdemand to rationalize the process of building which in turn ledto significant changes of the role of the architect, and furtherrestrained architectureâs dependency on rational means-endsdecision-making, favouring economic perspectives of building.QC 20140617</p

Reply to Comment by Galapon on 'Almost-periodic time observables for bound quantum systems'
In a recent paper [1] (also at http://lanl.arxiv.org/abs/0803.3721), I made
several critical remarks on a 'Hermitian time operator' proposed by Galapon [2]
(also at http://lanl.arxiv.org/abs/quant-ph/0111061).
Galapon has correctly pointed out that remarks pertaining to 'denseness' of
the commutator domain are wrong [3]. However, the other remarks still apply,
and it is further noted that a given quantum system can be a member of this
domain only at a set of times of total measure zero.Comment: 3 page
Discovery of hydroxyl and water masers in R Aquarii and H1-36 Arae
We present the first results from an all-sky maser-line survey of symbiotic
Miras. Interferometric spectral-line observations of R Aqr and H1-36 Arae have
revealed a 22-GHz water maser in the former and 1612-MHz hydroxyl and weak
22-GHz water maser emission from the latter. H1-36 has thus become the first
known symbiotic OH/IR star. We have also detected weak OH line emission from
the vicinity of R Aqr, but we note that there are small discrepencies between
the OH- and H2O-line velocities and positions. These detections demonstrate
unequivocally that dust can shield some circumstellar hydroxyl and water
molecules from dissociation, even in systems which possess intense local
sources of UV. Finally, we discuss some of the implications of these
observations. The narrow profile of the water maser in R Aqr means that there
may finally be an opportunity to determine the system's orbital parameters. We
also point out that high resolution synthesis observations may trace the
distribution of dust in H1-36 and R Aqr, possibly throwing light on the
mass-loss process in symbiotic Miras and placing constraints on the amount of
collimation experienced by UV radiation from their hot, compact companions.Comment: 7 pages; no figures attached; LaTex (MN style); postscript figures
