Shanghaied into the future: the Asianization of the future Metropolis in post-Blade Runner cinema

The clichéd 1930–1950 Western cinematic images of Shanghai as a fascinating den of iniquity, and, in contrast, as a beacon of modernity, were merged in Fritz Lang’s Metropolis. As a result, a new standard emerged in science ction lms for the representation of future urban conglomerates: the Asianized metropolis. e standard set by this lm, of a dark dystopian city, populated by creatures of all races and genetic codes, will be adopted in most of the representations of future cities in non-Asian cinema. is article traces the representation of Shanghai in Western cinema from its earliest days (1932– Shanghai Express) through Blade Runner (1982) to the present (2013– Her). Shanghai, already in the early 1930s, sported extremely daring examples of modern architecture and, at the same time, in non-Asian cinema, was represented as a city of sin and depravity. is dualistic representation became the standard image of the future Asianized city, where its debauchery was o en complemented by modernity; therefore, it is all the more seedy. Moreover, it is Asianized, the “Yellow Peril” incarnated in a new, much more subtle, much more dangerous way. As such, it is deserving of destruction, like Sodom and Gomorrah

Time domains of the hypoxic ventilatory response in ectothermic vertebrates

Over a decade has passed since Powell et al. (Respir Physiol 112:123–134, 1998) described and defined the time domains of the hypoxic ventilatory response (HVR) in adult mammals. These time domains, however, have yet to receive much attention in other vertebrate groups. The initial, acute HVR of fish, amphibians and reptiles serves to minimize the imbalance between oxygen supply and demand. If the hypoxia is sustained, a suite of secondary adjustments occur giving rise to a more long-term balance (acclimatization) that allows the behaviors of normal life. These secondary responses can change over time as a function of the nature of the stimulus (the pattern and intensity of the hypoxic exposure). To add to the complexity of this process, hypoxia can also lead to metabolic suppression (the hypoxic metabolic response) and the magnitude of this is also time dependent. Unlike the original review of Powell et al. (Respir Physiol 112:123–134, 1998) that only considered the HVR in adult animals, we also consider relevant developmental time points where information is available. Finally, in amphibians and reptiles with incompletely divided hearts the magnitude of the ventilatory response will be modulated by hypoxia-induced changes in intra-cardiac shunting that also improve the match between O2 supply and demand, and these too change in a time-dependent fashion. While the current literature on this topic is reviewed here, it is noted that this area has received little attention. We attempt to redefine time domains in a more ‘holistic’ fashion that better accommodates research on ectotherms. If we are to distinguish between the genetic, developmental and environmental influences underlying the various ventilatory responses to hypoxia, however, we must design future experiments with time domains in mind

Fishing, reproductive volume and regulation: Population dynamics and exploitation of the Eastern Baltic cod

The relative importance of exploitation rate and environmental variability in generating \ufb02uctuations of harvested populations is a key issue in academic ecology as well as population management. We studied how the eastern Baltic cod (Gadus morhua) is affected by \ufb01shing and environmental variation by using a newly developed single species state-space model. Survey data and auxiliary environmental data were used to estimate the model parameters. The model was then used to predict future development of the eastern Baltic cod under different \ufb01shing mortalities and abiotic conditions. Abiotic condition was represented by an index: reproductive volume which is the volume of water suitable (in terms of salinity and oxygen content) for the successful development of the early life stages of Baltic cod. The model included direct density dependence, \ufb01shing, and a lagged effect of reproductive volume. Our analysis showed that \ufb01shing rate is approximately three times more important than reproductive volume in explaining the population dynamics. Furthermore, our model suggests either under- or over-compensatory dynamics depending on the reproductive volume and long term catch levels. It follows that \ufb01shing can either reduce or increase temporal oscillations of the cod stock depending on whether the dynamics is over- or undercompensatory, respectively. The sustainable level of \ufb01shing rate is however dependent on reproductive volume. Our model predicts a dual role of \ufb01shing rate, stabilizing when reproductive volume is high and destabilizing when it is low. Exploitation rate may therefore increase or decrease the risk of the population of cod dropping below a given biomass reference point depending on the environmental conditions, which has practical implications for \ufb01sheries management
