Sustainability is defined in terms of four overlapping positions, ranging from very weak to very strong sustainability. The core idea is of a non-declining capital stock (including natural capital) over generational time. Weak sustainability positions emphasise capital substitution possibilities and the power of technical process to mitigate resource depletion and pollution problems. Climate ch...

Objectives: An event-related brain potential (ERP) study investigated whether spatially selective processing in vision and audition is controlled by a single supramodal system or by independent modality-speci®c systems. Methods: Event-related brain potentials were recorded in response to visual and auditory stimuli at attended and unattended locations. In the `Attend Same' condition, attention ...

Background: Phenylketonuria (PKU) is one of the most common inherited metabolic disorders and first to be included on newborn screening. Even treated, it can impact quality life (QoL) due strict dietary management potential for neuropsychiatric symptoms including anxiety, depression, impaired executive functioning attention. This study aims learn about newest treatment PKU – pegvaliase, an enzy...

Some argue that peak conventional oil production is imminent due to physical resource scarcity. We examine the alternative possibility of reduced oil use due to improved efficiency and oil substitution. Our model uses historical relationships to project future demand for (a) transport services, (b) all liquid fuels, and (c) substitution with alternative energy carriers, including electricity. R...

Traditional techniques for project modelling have not adequately incorporated some factors that are essential for resource planning and management. This paper describes a new approach for project modelling that uses Timed Coloured Petri nets (TCPNs), to facilitate resource allocation in projects under constraints, commonly encountered in practice since TCPNs provide a powerful formalism for rep...

We incorporate a renewable resource into an overlapping generations model with standard, well-behaved utility and constant returns production functions. Besides being a factor of production the resource serves as a store of value. We characterize dynamics, efficiency and stability of steady state equilibria, and show that their nature depends on the size of the intertemporal elasticity of subst...

In this paper we invite the reader to a journey through three lambda calculi with resource control: the lambda calculus, the sequent lambda calculus, and the lambda calculus with explicit substitution. All three calculi enable explicit control of resources due to the presence of weakening and contraction operators. Along this journey, we propose intersection type assignment systems for all thre...

Paraphrases extracted from parallel corpora by the pivot method (Bannard and Callison-Burch, 2005) constitute a valuable resource for multilingual NLP applications. In this study, we analyse the semantics of unigram pivot paraphrases and use a graph-based sense induction approach to unveil hidden sense distinctions in the paraphrase sets. The comparison of the acquired senses to gold data from ...
