Film-Cinema-Spectator: Film Reception is a substantial tome in every sense of the term, containing German translations of important pieces originally published in English, such as Annette Kuhn's essay on heterotopy (27-41), and Thomas Elsaesser's analysis of spectating practices in early cinema (137-58).
He had first discussed heterotopy in his influential volume Everyday Life in the Modern World, written in 1967 and published early in 1968; in this context, Lefebvre used the word as a derivative not of utopia but of the term isotopy, which had been coined by linguists not long before.
Following this logic, we could say that heterotopy is the linguistic equivalent of uneven development in the capitalist economy.
13,14) For instance, the great extent to which changes in plant form have been engendered was by heterochrony (temporal shifts in developmental pathways) or heterotopy (spatial shifts in developmental pathways).
For example, many of the changes in plant forms have been engendered by heterochrony (temporal shifts in developmental pathways) or heterotopy (spatial shifts in developmental pathways).
Confronted with this limit, they wondered whether the unnamed island they were seeking might actually be the boat, a place without place, a perfect heterotopy.
Heterochrony changes the developmental timing and rate of development of the organ, without changing the developmental direction; heterotopy changes the nature of the organs formed, not the timing and rate of morphogenesis (Li & Johnston, 2000).
Other causes include heterotopy, the change of structural position, and homeosis, the replacement of a structure by another.
We will also discuss some of the limitations of heterochrony and suggest an integrative approach incorporating heterochrony, homeosis and heterotopy in plant ontogenetic and phylogenetic studies.
Other developmental mechanisms include homeosis, heterotopy, and homology.
