Relationships between occupational membership and personal consumption have long been an important area of social analysis. Occupational groups represent contexts consumption, where individuals’ advantages resources are accumulated often impose reproduction field-specific practices patterns behaviour. Drawing on Bourdieu’s conceptualization capitals using the British family expenditure survey, ...

Multiple signalling events interact in cancer cells. Oncogenic Ras cooperates with Egfr, which cannot be explained by the canonical signalling paradigm. In turn, Egfr cooperates with Hedgehog signalling. How oncogenic Ras elicits and integrates Egfr and Hedgehog signals to drive overgrowth remains unclear. Using a Drosophila tumour model, we show that Egfr cooperates with oncogenic Ras via Arf6...

Higher-order process calculi are calculi in which processes can be communicated. We study the expressiveness of strictly higher-order process calculi, and focus on two issues well-understood for first-order calculi but not in the higher-order setting: synchronous vs. asynchronous communication and polyadic vs. monadic communication. First, and similarly to the first-order setting, synchronous p...

Zahavi’s handicap principle, originally proposed as an explanation for sexual selection of elaborate male traits, suggests that a sufficient cost to dishonest signals can outweigh the rewards of deception and allow individuals to communicate honestly. Maynard Smith (1991) and Johnstone & Grafen (1992) introduce the Sir Philip Sidney game in order to extend the handicap principle to interactions...

The maximum likelihood (ML) and suboptimum ML (S-ML) detectors are derived in the first order moving average model. The ML and S-ML detectors are employed in the antipodal signaling system, and compared in terms of the bit-error-rate in impulsive environment. Numerical results show that the S-ML detector, despite reduced complexity and simpler structure, exhibits practically the same performanc...

This paper illustrates the use of priorities in process algebras by a real-world example dealing with the design of a safety-critical network which is part of a railway signaling system. Priorities in process algebras support an intuitive modeling of distributed systems since undesired inter-leavings can be suppressed. This fact also leads to a substantial reduction of the sizes of models. We h...

Sender–receiver models in the style of Lewis (1969), Hurford (1989), or Nowak and Krakauer (1999) can be used to explain meaning of signals in situations of cooperative interaction. This paper provides a complete characterization of neutrally stable strategies of this game purely in terms of properties of the lexical matrices that agents use for sending and receiving messages. It is show that i...

This study proposes an integrated ad hoc routing and time-slot scheduling (IARTSS) scheme to address the problem of ad hoc routing in Bluetooth networks. Our proposed scheme contains four main mechanisms to address the different facets of the problem, namely CompensationBased Time-Slot Assignment (CTSA), Traffic Differentiation Queueing (TDQ), Adaptive Master-Slave Switching (AMSS), and an Enha...

Mobile ad hoc networks (MANETs) are of primary interest as new networks because of their flexibility. The Session Initiation Protocol (SIP) is the main signaling system in 3G and SIP servlets the main service provisioning framework. SIP is now being considered as a basis for signaling in MANETs. This makes the SIP servlets framework a chief candidate for service provisioning in MANETs. In this ...

With the trend to partially move safety-related features from courtyards into on-board control software, new challenges arise in supporting such designs by formal verification capabilities, essentially entailing the need for a model-based design process. This paper reports on the usage of the STATEMATE Verification Environment to model and verify a radio-based signaling system, a trial case stu...
