Bare Life: Restroom Anxiety and the Urge for Control

This chapter takes up what might at first appear an unlikely setting for examining security dynamics: the public restroom. There are lessons to be taken from this venue, so often ignored in serious scholarship and indeed the usual basis only for jokes. Here we can see anxieties in play and all sorts of unsavory mechanisms, both at the micro and macro level, that come in response. The toilet allows us to see the combination of factors that repress—the usual culprits of class, race, and gender discrimination—but also soulful anxieties that come with the more basic human territory. Some degree of capitalist plot is happening, but that is only part of the story—a larger lesson to be considered across other less intimate realms, whether market-based or not. Whatever the combination of sources, the chapter points the way toward a safer and more pleasant toilet and one with the promise of ecological reform.

CONSTRUCTION OF MONODROMY MATRIX IN THE F-BASIS AND SCALAR PRODUCTS IN SPIN CHAINS

We present in a simple terms the theory of the factorizing operator introduced recently by Maillet and Sanches de Santos for the spin-1/2 chains. We obtain the explicit expressions for the matrix elements of the factorizing operator in terms of the elements of the monodromy matrix. We use this results to derive the expression for the general scalar product for the quantum spin chain. We comment on the previous determination of the scalar product of Bethe eigenstate with an arbitrary dual state. We also establish the direct correspondence between the calculations of scalar products in the F-basis and the usual basis.

Isomorphic embeddings of l1(Г) into subspaces of C(Ω)

Introduction. The embeddability of l1(Γ), for uncountable sets Γ, into subspaces of Banach spaces of the form C(Ω) was investigated first by Hagler in (6) and subsequently by Haydon in (7), (8) and Argyros and Negrepontis in (1). An important role in the development of the above subject is played by a lemma of Rosenthal (12) that translates the functional analytic problem of finding a family {fξ: ξ Γ} of elements of C(Ω) equivalent to the usual basis of l1(Γ) into the problem of the existence of an independent family {(Aξ, Bξ,): ξ є Γ} of closed subsets.

Forecasting Industrial Production

In February and August each year the National Institute publishes forecasts of growth in output for 24 separate industrial sectors which together comprise the index of industrial production. The forecasts are based mainly, though not entirely, upon macro-forecasts prepared by the Institute on the usual basis of assuming no change in government policies. This article contains a description and some tests of the econometric procedure used to derive the industrial forecasts from those yielded by the macro model. It must be emphasised, however, that the econometric procedure used to prepare the industrial forecasts represents only the first stage of a two-part method which yields the forecasts finally published in the Industrial Production chapter of the National Institute Economic Review. Although based upon the econometric forecasts, the final predictions incorporate adjustments made at the second stage of the procedure when up-to-date information on capacity constraints, strikes, tariffs and other factors is taken into account. In addition, adjustments may be necessary in the actual forecasting situation to ensure that the sum of the component forecasts adds up to the aggregate industrial production forecast (see page 61).

A Note on Complementary Subspaces in c0

A well known result of A. Pelcynski [2] states that each subspace of c0 which is isomorphic to c0 and of infinite deficiency has a complementary subspace which is itself isomorphic to c0. We are concerned here with the question of when there exists R, a subset of the integers, such that the complementary subspace X can actually be taken to be C0(R). That is, we are concerned with determining when the basis vectors for X can be chosen as a subset of the usual basis vectors for c0. If T: C0 → C0 is norm increasing and ‖T‖ < 2, it is not hard to see, as we shall show, that Tco admits a complement of the form C0(R). However, this bound cannot be improved; indeed, it is possible to construct norm increasing T: C0 → C0 such that ‖T‖ = 2 and yet Tc0 admits no such complement. The construction of such a T is the main point of this note. This construction also enables us to dispose of a speculation of ours in [1].

Liquid diffusivities for the system methanol–toluene

Measurements of the liquid diffusivities over the complete range of compositions of the methanol–toluene system at atmospheric pressure and 25°C have been carried out using the magnetically stirred porous diaphragm cell technique. Diffusivities calculated on the usual basis of concentration as driving force have a minimum of 0.80 × 10−5 cm2 s−1 at 0.4 mole fraction methanol. There is a threefold variation of diffusivity over the entire composition range, and the general behavior is similar to analogous nonideal systems. At infinite dilution none of the semi-empirical correlations, based on various models of the liquid state, give values in agreement with experiment.
