QUESTIONSABOUT THE PERFORMATIVE NATURE of Victorian culture have received extended attention in the past decade or so as critics have begun to examine the relationship between representation and subjectivity.1 By and large, such studies have fruitfully problematized our received assumptions about the private character of the Victorians. At the same time, however, they have also implicitly privileged the middle-class frames of reference that shape the distinction, for even as they complicate our understanding of performance by calling into question the distinction between public and private modes, critics who take up such issues tend not to question the stability of the categories of experience under scrutiny. As a result, while we gain important new insights into the cultural formation of identity or genre underwritten by the separation of public and private spheres, we also risk reading all Victorians as if their relationships to such ideological formations were identical with those of the emerging middle class.

Deng Xiaoping's reforms have changed the face of China: the economy has made epic strides, cities fly the banners of western capitalism, a new middle class aspires to full membership of the consumer society. In the process, political reform got left behind, repression of dissidents is as harsh as ever and a growing gap between rich and poor, town and country, threaten the stability of the Middle Kingdom

The One

For more than a decade scholars mostly from economy and development studies have described the rise of a newly emerging ‘middle class’ in the Global South including Africa. This has led to a ‘middle class narrative’ with the ‘middle class’ as the backbone of economic and democratic development. Especially with regard to the stability of the position of the people in the ‘middle’, empirical social science studies challenge the ‘middle class narrative’ and at their uncertainty and insecurity. This tension between upward mobility at the one hand uncertainty and instability at the other hand (the vulnerability-security nexus) and the options to cope with this challenge under the condition of limited provision of formal social security is the focus of this case study on Kenya. Instead of an analysis of inequality based on income, it is more helpful to start from the welfare mix and the role of social networks as main elements of provision of social security. Against this background, we identify different strategies of coping that go together with different sets of values and lifestyles, conceptualised as milieus, that are not determined by the socio-economic situation.

The ability to maintain a learned size discrimination in the face of alterations in size-irrelevant stimulus attributes was studied in 128 white middle-class children of normal intelligence ranging in age from 2 to 7 yr. Increase in chronological age resulted in increased competence in retaining a learned size discrimination in the face of alterations in aspects other than size. Marked instability of response was found at the 2- and 3-yr.-old level. A rapid change in the stability of learning was exhibited after 4 yr. Thereafter the children in successive age groups showed a continual improvement in the ability to sustain the learned response.

The effect of friendship reciprocation and friend aggression on the stability of aggression across a 6-month period following the transition to secondary school was studied in a sample of 298 Grade 6 children from a predominately white, middle-class, Midwestern American community. The stability of aggression was generally high but it varied as a function of (1) the level of aggression of both individuals in the friendship and (2) whether the friendship was reciprocated. For children with high initial levels of aggression, those with unreciprocated aggressive friends were the most stable in their aggression. For children with low initial levels of aggression, most children remained stably low in aggression, with type of friendship and friend aggression having little effect on stability. Adolescents who were high in aggression at time 1 (T1) and had an aggressive friend (reciprocated or not) remained aggressive at time 2 (T2), but those who were aggressive at T1 and had nonaggressive friends actually displayed much lower levels of aggression at T2. The opposite did not occur for those adolescents low in aggression at T1. Those low in aggression with aggressive friends at T1 did not increase in aggression. These findings were discussed in light of current thinking about the effect of friendship on development.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.

AbstractBy using the stability condition and general formulas developed by Fukushima (1998 = Paper I) we discovered that, just as in the case of the explicit symmetric multistep methods (Quinlan and Tremaine, 1990), when integrating orbital motions of celestial bodies, the implicit symmetric multistep methods used in the predictor-corrector manner lead to integration errors in position which grow linearly with the integration time if the stepsizes adopted are sufficiently small and if the number of corrections is sufficiently large, say two or three. We confirmed also that the symmetric methods (explicit or implicit) would produce the stepsize-dependent instabilities/resonances, which was discovered by A. Toomre in 1991 and confirmed by G.D. Quinlan for some high order explicit methods. Although the implicit methods require twice or more computational time for the same stepsize than the explicit symmetric ones do, they seem to be preferable since they reduce these undesirable features significantly.

The method demonstrated is an adaptation of a proven procedure for accurately determining the magnification of light photomicrographs. Because of the stability of modern electrical lenses, the method is shown to be directly applicable for providing precise reproducibility of magnification in various models of electron microscopes.A readily recognizable area of a carbon replica of a crossed-line diffraction grating is used as a standard. The same area of the standard was photographed in Phillips EM 200, Hitachi HU-11B2, and RCA EMU 3F electron microscopes at taps representative of the range of magnification of each. Negatives from one microscope were selected as guides and printed at convenient magnifications; then negatives from each of the other microscopes were projected to register with these prints. By deferring measurement to the print rather than comparing negatives, correspondence of magnification of the specimen in the three microscopes could be brought to within 2%.

The Stability

The strengthening effect at high temperature produced by a dispersed oxide phase in a metal matrix is seemingly dependent on at least two major contributors: oxide particle size and spatial distribution, and stability of the worked microstructure. These two are strongly interrelated. The stability of the microstructure is produced by polygonization of the worked structure forming low angle cell boundaries which become anchored by the dispersed oxide particles. The effect of the particles on strength is therefore twofold, in that they stabilize the worked microstructure and also hinder dislocation motion during loading.

The Stability

It is well known that the resolution of bio-molecules in a high resolution electron microscope depends not just on the physical resolving power of the instrument, but also on the stability of these molecules under the electron beam. Experimentally, the damage to the bio-molecules is commo ly monitored by the decrease in the intensity of the diffraction pattern, or more quantitatively by the decrease in the peaks of an energy loss spectrum. In the latter case the exposure, EC, to decrease the peak intensity from IO to I’O can be related to the molecular dissociation cross-section, σD, by EC = ℓn(IO /I’O) /ℓD. Qu ntitative data on damage cross-sections are just being reported, However, the microscopist needs to know the explicit dependence of damage on: (1) the molecular properties, (2) the density and characteristics of the molecular film and that of the support film, if any, (3) the temperature of the molecular film and (4) certain characteristics of the electron microscope used
