FROM VIOLENCE TO RECONSTRUCTION: THE MAKING, DISINTEGRATION AND REMAKING OF AN APARTHEID CITY

This article analyzes the relationship between violence and the racial city. It examines Durban's construction and disintegration in the context of unsuccessful apartheid reform, and traces corresponding distinct but overlapping stages of violence. Internecine violence of the latter 1980s constituted a racially displaced confrontation over political control and resources of the society transformed into internecine conflict within black residential areas, especially the urban peripheries. The violence was rooted in spatial and material differentiation reinforced by township and shantytown power structures, which clandestine state intervention accentuated. The article concludes by analyzing the new spatial and racial city forms, suggesting alternative urban reconstruction paths to redress the deeper causes of violence.     

NONLINEAR ANALYSIS OF REINFORCED CONCRETE SHEAR WALL UNDER EARTHQUAKE LOADING

A constitutive model for predicting the cyclic response of reinforced concrete structures is proposed. The model adopts the concept of a smeared crack approach with orthogonal fixed cracks and assumes a plane stress condition. Predictions of the model are compared firstly with existing experimental data on shear walls which were tested under monotonic and cyclic loading. The same model is then used in the finite element analysis of a complete shear wall structure which was tested under a large number of cyclic load reversals due to earthquake loading at NUPEC's Tadotsu Engineering Laboratory. Two different finite element approaches were used, namely a two-dimensional and a three-dimensional representation of the test specimen. The ability of the concrete model to -reproduce the most important characteristics of the dynamic behaviour of this type of structural element was evaluated by comparison with available experimental data. The numerical results showed good correlation between the predicted and the actual response, global as well as local response being reasonable close to the experimental one.     

SHAKING TABLE DYNAMICS: RESULTS FROM A TEST-ANALYSIS COMPARISON STUDY

This paper presents the results of a comprehensive comparison study between the analytically predicted and experimentally identified dynamics of the shaking table system built recently in the Structural Engineering Laboratory at Rice University in Houston, Texas. The primary objectives of the research presented here are two-fold: (1) to shed light into the dynamic performance of asmall-tc-medium size, uni-axial, servo-hydraulic, displacement-controlled shaking table system, and (2) to validate a linearised dynamic model of the system (in the form of the total shaking table transfer function) developed earlier by the authors from basic principles. The analytical model incorporates the inherent dynamic characteristics of the various components of the shaking table system (i.e. controller, servovalve, actuator, test specimen, and reaction mass) and their dynamic interaction.

The test-analysis correlation study performed over a wide range of operating and payload conditions provides useful information on the sensitivity of the shaking table transfer function to control gain parameters and how it can be used to tune the shaking table controller for optimum performance under various payload conditions. The good test-analysis correlation results obtained validate the analytical shaking table model, show its robustness, and provide keen insight into the underlying coupled dynamics of a shaking table system. In order to achieve this good test-analysis correlation, it was crucial to include a time delay in the analytical model of the shaking table system (innovative feature of the model to account for the time lag in the response of the servovalve-actuator system). The expected significant dynamic interaction between payload and shaking table is also confirmed by this study.     

The importance of location and scale in rural and small town tourism product development: The case of the Canadian Fossil Discovery Centre,Manitoba, Canada

This paper begins with a review of the literature on tourism in rural economies, to establish a framework for analyzing large‐scale tourism products in rural and small town regions. The review is followed by the development of a typology of large‐scale attractions in rural and small town regions, including parks, casinos, events, heritage, and cultural products. The typology leads into the example of the Canadian Fossil Discovery Centre (CFDC) in Manitoba, Canada. Located in an agricultural region of south‐central Manitoba, the community of Morden is located 125 km from the provincial capital city, Winnipeg, which had a population of 811,900 in 2016. Morden is also located 35 km north of the border with North Dakota. Thus, while a small town in a traditionally rural region still dependent upon an agricultural economic base, Morden has been recently successful in diversifying its economy, including through manufacturing, services, hospitality, and tourism. In part, this success is due to a south‐central Manitoba location; however, it is also the result of innovative local leadership, including the prioritization of hospitality and tourism related to the CFDC. This paper describes the case study as an example of successful tourism development within an already economically and socially diversifying region.     

Cargo Cults and Discursive Madness

Understood as mimetic portrayals of the image of unlimited good projected by European colonial culture, Melanesian ‘cargo cults’ are therefore viewed as ‘irrational’ within indigenous understandings. Consequently, Western anthropological discourse has sought to functionally normalize and nativize ‘cargo cult’ behaviors at the expense of denying their non‐rational character. The result has been a lexical and semantic uncertainty and explanatory instability in ‘cargo cult’ discourse that can be analyzed as a type of discursive ‘madness.’ A strategy of reading the ‘madness’ of ‘cargo cult’ discourse is outlined and applied to key anthropological texts, in particular Peter Worsley's The Trumpet Shall Sound.
