The introduction of social adaptation within evacuation modelling

In recent history, a number of tragic events have borne a consistent message; the social structures that existed prior to and during the evacuation significantly affected the decisions made and the actions adopted by the evacuating population in response to the emergency. This type of influence over behaviour has long been neglected in the modelling community. This paper is an attempt to introduce some of these considerations into evacuation models and to demonstrate their impact. To represent this type of behaviour within evacuation models a mechanism to represent the membership and position within social hierarchies is established. In addition, individuals within the social groupings are given the capacity to communicate relevant pieces of data such as the need to evacuate—impacting the response time—and the location of viable exits—impacting route selection. Furthermore, the perception and response to this information is also affected by the social circumstances in which individuals find themselves. Copyright © 2005 John Wiley & Sons, Ltd.

Exploring adaptation & self-adaptation in autonomic computing systems

This panel paper sets out to discuss what self-adaptation means, and to explore the extent to which current autonomic systems exhibit truly self-adaptive behaviour. Many of the currently cited examples are clearly adaptive, but debate remains as to what extent they are simply following prescribed adaptation rules within preset bounds, and to what extent they have the ability to truly learn new behaviour. Is there a standard test that can be applied to differentiate? Is adaptive behaviour sufficient anyway? Other autonomic computing issues are also discussed.

Model-based pilot and data power adaptation in psam with periodic delayed feedback

We consider the optimum design of pilot-symbol-assisted modulation (PSAM) schemes with feedback. The received signal is periodically fed back to the transmitter through a noiseless delayed link and the time-varying channel is modeled as a Gauss-Markov process. We optimize a lower bound on the channel capacity which incorporates the PSAM parameters and Kalman-based channel estimation and prediction. The parameters available for the capacity optimization are the data power adaptation strategy, pilot spacing and pilot power ratio, subject to an average power constraint. Compared to the optimized open-loop PSAM (i.e., the case where no feedback is provided from the receiver), our results show that even in the presence of feedback delay, the optimized power adaptation provides higher information rates at low signal-to-noise ratios (SNR) in medium-rate fading channels. However, in fast fading channels, even the presence of modest feedback delay dissipates the advantages of power adaptation.

'Marginal gothic': mediating the monstrous in British romanticism

In this paper I look at texts from the Romantic Period which strategically employ elements of the Gothic genre in what I describe as a `marginal` relationship with the Gothic canon. My intention is both to explore the way the boundaries of the genre might be extended, and to cast fresh light on some of the texts discussed, specifically in relation to the ways in which the `monstrous` is perceived and portrayed as villainy. In the first half of the paper, using Burke’s Philosophical Enquiry on the Sublime and the Beautiful as a starting point, I consider Burke’s Reflections on the Revolution in France, Godwin’s Caleb Williams, Radcliffe’s The Italian, and Blake’s The Marriage of Heaven and Hell as all in various ways examples of `marginal Gothic` that present evil doing as monstrous aberrations, also noting the contemporary reception of Beckford’s Vathek, praised in 1786 for its `accuracy and credibility`. In addition, I suggest that Wordsworth’s `Tintern Abbey` and Book VI of The Prelude provide evidence of marginal, but significant, Gothic influence that references Radcliffe’s and Burke’s explorations of a terror of the unknown. In the second half of the paper I focus on Scott’s Guy Mannering, or The Astrologer (1815) as an important example of a `marginal` Gothic novel. Scott’s reference to Vathek at a key point in his plot suggests that he had read Beckford’s novel as entirely `Gothic`. This discussion incorporates a comparison between Mannering’s youthful enthusiasm for astrological divination, and themes to be found in Shelley’s Frankenstein, notably with respect to the nature of Victor Frankenstein’s response to `old` and `new` science and medicine, and to the creation and control of Gothic monstrosity. In these and in other instances, it will be argued that the `marginal Gothic` of Scott’s novel may be read as a precursor to Shelley’s work. [From the Author]

Models of advertising standardisation and adaptation: it's time to move the debate forward

Advertising standardisation versus adaptation has been discussed in some detail in the marketing literature. Despite previous attempts, there is still no widely-used decision-making model available that has been accepted by marketing practitioners and academics. This paper examines the development of this important area by reviewing six prominent models in the advertising standardisation/adaptation literature. It shows why there has been a lack of development in the current literature and why it is crucial to address this problem. Important areas for future research are suggested in order to find a solution

Physiological Adaptation Of Mytilus-Edulis To Cyclic Temperatures

Mytilus edulis adapted to cyclic temperatures by reducing the amplitude of response of oxygen consumption and filtration rate over a period of approximately two weeks, and thereby increasing their independence of temperature within the range of the fluctuating regime. When acclimated to cyclic temperature regimes within the range from 6 to 20°C, the metabolic and feeding rates, measured at different temperatures in the cycle, were not significantly different from the adapted response to equivalent constant temperatures. Physiological adaptation ofMytilus edulis to different thermal environments was reflected in their metabolic and feeding rate-temperature curves. Animals subjected to marked diel fluctuations in environmental temperature showed an appropriate region of temperature-independence, whereas animals from a population not experiencing large diel temperature fluctuations showed no region of temperature-independence. In a fluctuating thermal environment which extended above the normal environmental maxima, respiratory adaptation occurred at higher temperatures than was possible in a constant thermal environment. The feeding rate was also maintained at higher temperatures in a cyclic regime than was possible under constant thermal conditions. This represented a shortterm extension of the zone of activity in a fluctuating thermal environment. The net result of these physiological responses to high cyclic and constant temperatures has been assessed in terms of ‘scope for growth’. Animals acclimated to cyclic temperatures between 21 and 29°C had a higher scope for growth at 29°C and were less severely stressed than those maintained at the constant temperature of 29°C.
