Gendered Representations of Apartheid: The Women’s Jail Museum at Constitution Hill

This article examines the ways in which women are represented and remembered at The Women’s Jail at Constitution Hill museum, a former women’s jail that was used to incarcerate women during apartheid in Johannesburg, South Africa. Based on fieldwork at the museum, this study examines how the memory of the former prisoners and of the apartheid regime is shaped and narrated at this site. Situating our analysis within the context of the collective memory of apartheid, we examine how the museum uses artifacts and objects to depict both the specific forms of gendered dehumanization that women experienced at the jail, as well as their journeys to incarceration as a result of discriminatory apartheid laws. We also examine the absence of torture memory and references to hierarchical structures and interactions within the jail itself, noting that these were important dynamics of prison life that are not represented in the museum. This research presents a content and visual analysis of how the use of images and artifacts may illuminate and/or silence specific memories of degradation and humiliation in a museum space.Key Words: Collective Memory, Museums, Representation, South Africa, ApartheidMemorialization, Gender and Memorializatio

Sophtalk tutorials

This paper presents the Sophtalk system through two tutorials that describe salient features of the system and explore appropriate design methods. Sophtalk implements an event model of communication. System objects, called stnodes, emit messages when significant events occur, such as the termination of a computation, a request for a service from another object, error condition- s, etc. Messages circulate asynchronously in a network of stnodes. An stnode's type determines which messages it will receive, upon reception an action corresponding to the message and stnode instance is triggered. In the first tutorial, a small network in which a calculator - possibly in a seperate process - serves several clients, we introduce the essential Sophtalk functionalities. In the second tutorial a news network, we concentrat- e on design aspects and illustrate traps to be avoided

Biochemical Composition of Embryonic Blue Crabs \u3ci\u3eCallinectes sapidus\u3c/i\u3e Rathbun 1896 (Crustacea : Decapoda) from the Gulf of Mexico

Blue crab Callinectes sapidus embryos from the Mississippi Sound were sampled in spring and in late summer to determine patterns of biochemical composition and of yolk utilization during embryogenesis and to ascertain potential seasonal differences in biochemical composition. The diameter of spring embryos was similar to 6% greater than summer embryos but this significant size difference was due to increased water content, not to increased organic content. The general trend in initial biochemical composition was similar in both seasons; protein was the primary component at similar to 50% of initial dry weight followed by lipid (similar to 30%), ash (similar to 8%) and carbohydrate (6%). The general trend for utilization of organic reserves during embryogenesis was also similar seasonally. Lipid was the primary component metabolized during embryogenesis (44-48% of initial stores were utilized) followed by protein (13-16% utilized) and carbohydrate (similar to 13% utilized). Calculated on a dry weight basis, spring embryos had significantly lower lipid but significantly higher ash than summer embryos; there were no significant seasonal differences in protein or carbohydrate. Caloric expenditure on a dry weight basis was significantly different seasonally. There appear to be geographic differences among blue crabs; our results differ from those of a previous study of blue crab embryos from North Carolina waters

The Sophtalk reference manual

This is the reference manual for the LeLisp implementation of the Sophtalk system. Sophtalk is a set of tools that enable one to program the interaction between objects following an event model of communication. System objects, called stnodes emit messages when significant events occur such as the termination of a computation a request for a service from another object, error conditions, etc. Messages circulate asynchronously in a network of stnodes. An stnode's type determines which messages it will receive, upon reception an action corresponding to the message and stnode instance is triggered. Messages may also circulate between processes. The manual describes the three modules of Sophtalk : stnode, a multicast communication mechanism : stio an extension of the standard LeLisp asynchronous and synchronous i/o mechanisms : and stservice, which offers interprocess communication at the shell and LeLisp levels

Sensitivity of Fischer-Tropsch Synthesis and Water-Gas Shift Catalystes to Poisons form High-Temperature High-Pressure Entrained-Flow (EF) Oxygen-Blown Gasifier Gasification of Coal/Biomass Mixtures

There has been a recent shift in interest in converting not only natural gas and coal derived syngas to Fischer-Tropsch synthesis products, but also converting biomass-derived syngas, as well as syngas derived from coal and biomass mixtures. As such, conventional catalysts based on iron and cobalt may not be suitable without proper development. This is because, while ash, sulfur compounds, traces of metals, halide compounds, and nitrogen-containing chemicals will likely be lower in concentration in syngas derived from mixtures of coal and biomass (i.e., using entrained-flow oxygen-blown gasifier gasification gasification) than solely from coal, other compounds may actually be increased. Of particular concern are compounds containing alkali chemicals like the chlorides of sodium and potassium. In the first year, University of Kentucky Center for Applied Energy Research (UK-CAER) researchers completed a number of tasks aimed at evaluating the sensitivity of cobalt and iron-based Fischer-Tropsch synthesis (FT) catalysts and a commercial iron-chromia high temperature water-gas shift catalyst (WGS) to alkali halides. This included the preparation of large batches of 0.5%Pt-25%Co/Al{sub 2}O{sub 3} and 100Fe: 5.1Si: 3.0K: 2.0Cu (high alpha) catalysts that were split up among the four different entities participating in the overall project; the testing of the catalysts under clean FT and WGS conditions; the testing of the Fe-Cr WGS catalyst under conditions of co-feeding NaCl and KCl; and the construction and start-up of the continuously stirred tank reactors (CSTRs) for poisoning investigations

Frequency- and time-resolved photocurrents in vacuum-deposited stabilised a-Se films: the role of valence alternation defects

We report experimental results on photocurrent spectroscopy (frequency-resolved spectroscopy (FRS) and single-time transients), on vacuum-deposited a-Se films. We show that all measured photocurrents depend critically on the relative time spent by the material in the light and in the dark. We identify that the observed pronounced variation in optical response depends on the density of trapped (optically injected) charge within 200 nm of the surface and show that it is the ratio of dark and light exposure time that controls the density of such charge. Our data confirm that the localised charge radically influences the photocurrent transient shape due to the effective screening of the applied field within 200 nm of the surface. The field modification occurs over the optical extinction depth and changes both the photogeneration process and the drift of carriers. Many aspects of our data carry the signature of known properties of valence alternation pair (VAP) defects, which control many properties of a-Se. Modelling in the time domain shows that light generation of VAPs followed by optically triggered VAP defect conversion can lead to near-surface charge imbalance, demonstrating that VAP defects can account for the unusual optical response. The stabilised a-Se films were deposited above the glass transition temperature of the alloy with composition a-Se:0.3% As doped with ppm Cl. Electron paramagnetic resonance measurements at temperatures down to 5 K did not detect any spin active defects, even under photoexcitation above band gap
