Settler Colonialism, Decolonization, and Climate Change

The article proposes that climate change makes enduring colonial injustices and structures visible. It focuses on the imposition and dominance of colonial concepts of land and self-determination on Indigenous peoples in settler states. It argues that if the dominance of these colonial frameworks remains unaddressed, the progressing climate change will worsen other colonial injustices, too. Specifically, Indigenous self-determination capabilities will be increasingly undermined, and Indigenous peoples will experience the loss of what they understand as relevant land from within their own ontologies of land. The article holds that even if settler states strive to repair colonial injustices, these efforts will be unsuccessful if climate change occurs and decolonization is pursued within the framework of a settler colonial ontology of land. Therefore, the article suggests, decolonization of the ontologies of land and concepts of self-determination is a precondition for a just response to climate change

Stochastic Resonance in Chaotic Spin-Wave Dynamics

We report the first experimental observation of noise-free stochastic resonance by utilizing the intrinsic chaotic dynamics of the system. To this end we have investigated the effect of an external periodic modulation on intermittent signals observed by high power ferromagnetic resonance in yttrium iron garnet spheres. Both the signal-to-noise ratio and the residence time distributions show the characteristic features of stochastic resonance. The phenomena can be explained by means of a one-dimensional intermittent map. We present analytical results as well as computer simulations.Comment: 4 pages, revtex, 5 eps figures included, also available "via www http://athene.fkp.physik.th-darmstadt.de/public/wolfram.html" or "via ftp ftp://athene.fkp.physik.th-darmstadt.de/pub/publications/wolfram/", Phys.

Precipitation and the Interaction of Seedhead Biological Control Insects for Spotted Knapweed in the Rocky Mountain Front Range

Biological control of spotted knapweed (Centaurea stoebe) is an ongoing topic of research that holds ecological importance due to the extent to which knapweed has spread across the Western United States. Using herbivores (insects) as biological controls of spotted knapweed can be successful at reducing plant density in certain habitats. However, the exact relationship among the insects, knapweed, and abiotic factors affecting knapweed growth such as precipitation, remains uncertain. Through collection and dissection of knapweed seedheads, I estimated densities of two insects, Larinus minutus and Urophora affinis, as well as the average number of seeds produced by seedheads of spotted knapweed at a long-term study site in the Front Range of Colorado The data I collected were then added to a data set collected at this site extending back to 2002, which represents the longest data set of its kind presently available. After inclusion of my data, I found a positive trend between precipitation and seed production that differed from the findings of previous work. Insect presence decreased the number of seeds per seedhead, and this effect was independent of the amount of precipitation. I also found that the interaction of the two species of insects in the seedheads negatively affected the individual effectiveness of each insect, although not significantly, which supports previous research. My findings will benefit model predictions for knapweed spread and inform land management decisions about spotted knapweed infestations in the Rocky Mountain Front Range

Who Needs to Tell the Truth? - Epistemic Injustice and Truth and Reconciliation Commissions for Minorities in Non-Transitional Societies

Truth and Reconciliation Commissions (TRCs) have become a widely used tool to reconcile societies in the aftermath of widespread injustice or social and political conflict in a state. This article focuses on TRCs that take place in non-transitional societies in which the political and social structures, institutions, and power relations have largely remained in place since the time of injustice. Furthermore, it will focus on one particular injustice that TRCs try to address through the practice of truth-telling, namely the eradication of epistemic injustice. The article takes the Canadian and Norwegian TRCs as two examples to show that under conditions of enduring injustice, willful ignorance of the majority, and power inequality, TRCs might create a double bind for victims which makes them choose between epistemic exploitation and continued injustices based on the majority’s ignorance. The article argues that the set-up and accompanying measures of TRCs are of the utmost importance if TRCs in non-transitional societies are to overcome epistemic injustice, instead of creating new relations of exploitation

Delayed feedback control of periodic orbits in autonomous systems

For controlling periodic orbits with delayed feedback methods the periodicity has to be known a priori. We propose a simple scheme, how to detect the period of orbits from properties of the control signal, at least if a periodic but nonvanishing signal is observed. We analytically derive a simple expression relating the delay, the control amplitude, and the unknown period. Thus, the latter can be computed from experimentally accessible quantities. Our findings are confirmed by numerical simulations and electronic circuit experimentsComment: 4 pages, Revtex, manuscript also available at ftp://athene.fkp.physik.th-darmstadt.de/pub/publications/wolfram/prl_98a/ or at http://athene.fkp.physik.th-darmstadt.de/public/wolfram_publ.htm
