Among Umwelten: Meaning-Making in Critical Posthumanism

Conceptualizations of meaning ground formulations of human/nonhuman animal similarity and difference. Anthropocentric accounts of meaning-making are increasingly untenable in light of contemporary knowledge of nonhuman life, yet they remain influential, implicit and intractable even within conceptual frameworks that otherwise reject their explicit premises. This study traces dynamic, process-oriented notions of meaning from Jakob von Uexkll's seminal work through autopoietic, phenomenological, biosemiotic and Deleuzian thought. I critically examine how this lineage counters Cartesian dualist and humanist notions of meaning-making in favour of a view of meaning as dynamic process. The relationship between organism and environment is characterized by Uexkll as a relationship of meaning. Uexkll envisions life as myriad complex melodic relations that entwine organism and environment in a practice of meaning-making. Uexkll's work and its extensions across a range of disciplines form a rich theoretical foundation for contemporary critical posthumanist efforts to change how human/nonhuman animal difference and similarity is conceptualized. Contemporary critical posthumanism especially the work of Karen Barad, Rosi Braidotti, Elizabeth Grosz and Cary Wolfe works to resituate human meaning-making within a wider ecological context. Yet a cohesive and comprehensive view of meaning grounded in critical posthumanism and its foundational works is fragmented across a broad and complex disciplinary and conceptual terrain. I draw out and develop from this literature the key components for a critical posthumanist concept of meaning

Countdown to 2010: Can we assess Ireland’s insect species diversity and loss?

peer-reviewedThe insects are the most diverse organisms on this planet and play an essential role in ecosystem functioning, yet we know very little about them. In light of the Convention on Biological Diversity, this paper summarises the known insect species numbers for Ireland and questions whether this is a true refl ection of our insect diversity. The total number of known species for Ireland is 11,422. Using species accumulation curves and a comparison with the British fauna, this study shows that the Irish list is incomplete and that the actual species number is much higher. However, even with a reasonable knowledge of the species in Ireland, insects are such speciose, small, and inconspicuous animals that it is diffi cult to assess species loss. It is impossible to know at one point in time the number of insect species in Ireland and, although it is useful to summarise the known number of species, it is essential that biodiversity indicators, such as the Red List Index, are developed

Modelling the Effect of Device Geometry on Concentration Ratios of Quantum Dot Solar Concentrators

Quantum dot solar concentrators (QDSCs) are static, nonimaging concentrators which concentrate both direct and diffuse light. Using Monte-Carlo ray-trace modelling, concentration ratios (C) were predicted for QDSCs of different 2-D geometries. The optimum shape and size were determined, for given system parameters, by calculating the relative cost per unit power output. Devices with different 3-D geometry were also compared. The thickness of the plate was varied and devices with tapered thickness were modelled to investigate the effect on C

Performance of a campus photovoltaic electric vehicle charging station in a temperate climate

A photovoltaic (PV) array can be combined with battery energy storage to satisfy the electrical demand of lightweight electric vehicles. Measured solar resource and vehicle energy consumption, together with locational, mechanical and electrical constraints were used to design a vehicle charging station comprised of a 63 m2 10.5 kW AC PV array, with a 9.6 kWh lithium-ion battery. PV output, battery charge and discharge, electricity flows were monitored over one year. Deviations between measured and calculated annual AC generation averaged to 14%. Average annual direct consumption, self-consumption and system self-sufficiency were 8.47%, 30.3% and 74.36% respectively
