    Description: This paper reveals how urban theories traditionally rooted in northern cities and academies are challenged and redeveloped by southern perspectives. Critiques of urban theory as narrowly northern (or Anglo-American) have recently emerged, spawning the comparative urbanism movement that calls for urban theories to be open to the experiences of all cities. Using the example of the sale of state-subsidised houses in South Africa, this research uses two parallel concepts, gentrification and downward raiding, to challenge the northern empirical focus of urban theory. Despite describing similar processes of urban class-based change, the concepts are rarely considered analogous, entrenched in divergent empirical contexts and academic literatures. While gentrification debates largely reference the northern central city, downward raiding is reserved for the southern 'slum'. In contrast, this research develops 'hybrid gentrification' as a concept and methodological approach that demonstrates how non-northern urban experiences can and should create and refine urban theory.

    Description: The chapters in this timely volume aim to answer the growing interest in Arthur Schopenhauer's logic, mathematics, and philosophy of language by comprehensively exploring his work on mathematical evidence, logic diagrams, and problems of semantics. Thus, this work addresses the lack of research on these subjects in the context of Schopenhauer's oeuvre by exposing their links to modern research areas, such as the "proof without words" movement, analytic philosophy and diagrammatic reasoning, demonstrating its continued relevance to current discourse on logic. Beginning with Schopenhauer's philosophy of language, the chapters examine the individual aspects of his semantics, semiotics, translation theory, language criticism, and communication theory. Additionally, Schopenhauer's anticipation of modern contextualism is analyzed.  The second section then addresses his logic, examining proof theory, metalogic, system of natural deduction, conversion theory, logical geometry, and the history of logic. Special focus is given to the role of the Euler diagrams used frequently in his lectures and their significance to broader context of his logic. In the final section, chapters discuss Schopenhauer's philosophy of mathematics while synthesizing all topics from the previous sections, emphasizing the relationship between intuition and concept. Aimed at a variety of academics, including researchers of Schopenhauer, philosophers, historians, logicians, mathematicians, and linguists, this title serves as a unique and vital resource for those interested in expanding their knowledge of Schopenhauer's work as it relates to modern mathematical and logical study.

    Description: Logicians have often suggested that the use of Euler-type diagrams has influenced the idea of the quantification of the predicate. This is mainly due to the fact that Euler-type diagrams display more information than is required in traditional syllogistics. The paper supports this argument and extends it by a further step: Euler-type diagrams not only illustrate the quantification of the predicate, but also solve problems of traditional proof theory, which prevented an overall quantification of the predicate. Thus, Euler-type diagrams can be called the natural basis of syllogistic reasoning and can even go beyond. In the paper, these arguments are presented in connection with the book Nucleus Logicae Weisaniae by Johann Christian Lange from 1712.

    Description: In early modernity, one can find many spatial logic diagrams whose geometric forms share a family resemblance with religious art and symbols. The family resemblance these diagrams bear in form is often based on a vesica piscis or on a cross: Both logic diagrams and spiritual symbols focus on the intersection or conjunction of two or more entities, e.g. subject and predicate, on the one hand, or god and man, on the other. This paper deals with the development and function of logic diagrams, their analogy to religious art and symbols, and their modern application in artificial intelligence.

    Description: In the global South, policies providing property titles to low‐income households are increasingly implemented as a solution to poverty. Integrating poor households into the capitalist economy using state‐subsidized homeownership is intended to provide poor people with an asset that can be used in a productive manner. In this article the South African ‘housing subsidy system’ is assessed using quantitative and qualitative data from in‐depth research in a state‐subsidized housing settlement in the city of Cape Town. The findings show that while state‐subsidized property ownership provides long‐term shelter and tenure security to low‐income households, houses have mixed value as a financial asset. Although state‐subsidized houses in South Africa are a financially tradable asset, transaction values are too low for low‐income vendors to reach the next rung on the housing ladder, the township market. Furthermore, low‐income homeowners are reticent to use their (typically primary) asset as collateral security for credit, and thus property ownership is not providing the financial returns that titling theories assume. Résumé Les pays du Sud instaurent de plus en plus souvent des politiques publiques qui octroient des titres de propriété aux ménages à faible revenu afin de lutter contre la pauvreté. Intégrer les ménages défavorisés à l'économie capitaliste en leur permettant une accession à la propriété financée par l'État a pour but de leur procurer un bien utilisable de manière productive. Le système sud‐africain de logements subventionnés est évaluéà partir de données quantitatives et qualitatives issues d'une étude détaillée sur une implantation de logements subventionnés par l'État dans la ville du Cap. Les résultats montrent que, dans ce cadre, l'accession à la propriété offre aux ménages défavorisés un abri à long terme et une sécurité de maintien dans les lieux, mais que les maisons ont une valeur inégale sur le plan financier. Même si celles‐ci constituent un bien négociable financièrement, les valeurs de transaction sont trop faibles pour que les vendeurs à bas revenu puissent atteindre l'échelon suivant sur l'échelle des logements: le marché des townships. En outre, comme les nouveaux propriétaires rechignent à recourir à leur bien (généralement principal) pour garantir un crédit, l'accession à la propriété ne procure pas les bénéfices financiers théoriquement associés à la délivrance de titres de propriété.

    Description: This paper considers the impact of urban South Africa's new spatial order on its already fragile social dynamics. Analysis considers the relationships between residents of a gated community and their neighbouring (non-gated) area, addressing both the attitudes and perceptions that exist amongst residents of each area towards the 'other' neighbourhood, as well as the nature of any direct contact between residents. The case study for this paper is located in a master plan private development, constructed in 1999 in the heart of Cape Town's wealthy (and predominantly White) 'southern suburbs'. The development hosts two vastly different residential areas that despite spatial proximity are socially and functionally isolated.

    Description: A widely debated question in current research centres on determining the precursors to G. W. F. Hegel's theory of recognition. Until now Fichte, Rousseau and Aristotle have been discussed. However, the present paper analyses a further surprising correspondence between Marsilio Ficino's theory of love and Hegel's theory of recognition. Here it is shown that Hegel studied Ficino in 1793 and that we can discover syntactical, semantical, and structural vestiges of Ficino's De amore II 8 in Hegel's early fragments on religion (1793) and love (1797), which are closely related to the general theory of recognition found in the Phenomenology of Spirit. Not only may this thesis be relevant for Hegel or Ficino scholarship, but it could also be a further indication that social theories with normative content are an integral characteristic of (early) modern self-consciousness.

    Description: 1. Resource quality can have conflicting effects on the spread of disease. High-quality resources could hinder disease spread by promoting host immune function. Alternatively, high-quality food might enhance the spread of disease through other traits of hosts or parasites. Thus, to assess how resource quality shapes epidemics, we need to delineate mechanisms by which food quality affects key epidemiological traits. 2. Here, we disentangle effects of food quality on 'transmission potential' – a key component of parasite fitness that combines transmission rate and parasite production – using a zooplankton host and fungal parasite. We estimated the components of transmission potential (i.e. parasite encounter rate, susceptibility and yield of parasite propagules) for hosts fed a high-quality green alga and a low-quality cyanobacterium. 3. A focal experiment was designed to disentangle food quality effects on various components of transmission potential. The low-quality resource decreased transmission potential by stunting host growth and altering foraging behaviour. Hosts reared on low-quality food were smaller and had lower size-corrected feeding rates. Due to their slower grazing, they encountered fewer parasite spores in the water. Smaller hosts also had lower risk of an ingested spore causing infection (i.e. lower susceptibility) and yielded fewer parasite propagules. Hosts switched from high- to low-quality food during spore exposure also had low transmission potential – despite their large size – because the poor quality resource strongly depressed foraging. 4. A follow-up experiment investigated traits of the low-quality resource that might have driven those results. Cyanobacterial compounds that can inhibit digestive proteases of a related grazer likely did not cause the observed reductions in transmission potential. 5. Our study highlights the value of using mechanistic models to pinpoint how resource quality can change transmission potential. Overall, our results show that low-quality resources could inhibit the spread of disease through effects on multiple components of transmission potential. They also provide insight into how disease outbreaks in wildlife may respond to shifts in resource quality caused by eutrophication or climate change.

    Description: This paper examines the fear of crime in post-apartheid South Africa and its impact on urban space and form, focusing in particular on Cape Town. South African statistics point to alarming increases in serious crime over recent years and, although such statistics are considered unreliable, reflecting to some extent increases in the rate of crime reporting, the public perception is nonetheless one of decreased security. Attempts to mitigate fear have resulted increasingly in the creation of fortified enclaves and a withdrawal from public space. Although the more extreme manifestations are restricted to affluent areas, levels of residential protection have increased among all groups. As in other parts of the world, this “architecture of fear” results in growing danger within the public domain and the increasing polarization of social groups. The paper argues that this trend in South Africa perpetuates the social divisions that were inherent in the apartheid state into the post-apartheid context, with the fear of crime being used as a justification for a predominantly racist fear of difference.
