Rounded Edges: Modernism and Architectural Dialogue in Ho Chi Minh City
It is widely considered that there is no critical mass of architecture in a homogeneous style in Ho Chi Minh City, in contrast to Hanoi. This essay seeks to establish Ho Chi Minh City’s architectural heritage as a significant one, by arguing that the city does actually possess a critical mass of cohesive, remarkably well-designed buildings in modernist styles. Highlighted here is a unique feature of these modernist buildings: rounded, curved corners as a recurring motif in a dense urban center. The author argues that such buildings, dating from the 1920s through the 1970s, have provided the center of Ho Chi Minh City unique, cohesive, and striking characteristics and that they form one of the great ensembles of modernist architecture anywhere. This essay aims to re-locate the place of Ho Chi Minh City on the world map of the circulation of modernism, by emphasizing the internal dynamic of the city’s architectural evolution that transcends the colonial-postcolonial divide, and highlighting the evolution of forms revealing a continuity in spite of event-based ruptures in history. The significant presence of modernist buildings with curved corners in Phnom Penh, and their similarities to those of Ho Chi Minh City, suggest that regional circulation also played a crucial role

Distinguishing between anticipatory and responsive plasticity in a seasonally polyphenic butterfly
Seasonal generations of short-lived organisms often differ in their morphological, behavioural and life history traits, including body size. These differences may be either due to immediate effects of seasonally variable environment on organisms (responsive plasticity) or rely on presumably adaptive responses of organisms to cues signalizing forthcoming seasonal changes (anticipatory plasticity). When directly developing individuals of insects are larger than their overwintering conspecifics, the between-generation differences are typically ascribed to responsive plasticity in larval growth. We tested this hypothesis using the papilionid butterly Iphiclides podalirius as a model species. In laboratory experiments, we demonstrated that seasonal differences in food quality could not explain the observed size difference. Similarly, the size differences are not likely to be explained by the immediate effects of ambient temperature and photoperiod on larval growth. The qualitative pattern of natural size differences between the directly developing and diapausing butterflies could be reproduced in the laboratory as a response to photoperiod, indicating anticipatory character of the response. Directly developing and diapausing individuals followed an identical growth trajectory until the end of the last larval instar, with size differences appearing just a few days before pupation. Taken together, various lines of evidence suggest that between-generation size differences in I. podalirius are not caused by immediate effects of environmental factors on larval growth. Instead, these differences rather represent anticipatory plasticity and are thus likely to have an adaptive explanation. It remains currently unclear, whether the seasonal differences in adult size per se are adaptive, or if they constitute co-product of processes related to the diapause. Our study shows that it may be feasible to distinguish between different types of plasticity on the basis of empirical data even if fitness cannot be directly measured, and contributes to the emerging view about the predominantly adaptive nature of seasonal polyphenisms in insects
