A binary self-organizing map and its FPGA implementation
A binary Self Organizing Map (SOM) has been designed and
implemented on a Field Programmable Gate Array (FPGA) chip. A novel learning algorithm which takes binary inputs and maintains tri-state weights is presented. The binary SOM has the capability of recognizing binary input sequences after training. A novel tri-state rule is used in updating the network weights during the training phase. The rule implementation is highly suited to the FPGA architecture, and allows extremely rapid training. This architecture may be used in real-time for fast pattern clustering and classification of the binary features
A modified neural network model for Lobula Giant Movement Detector with additional depth movement feature
The Lobula Giant Movement Detector (LGMD) is a wide-field visual neuron that is located in the Lobula layer of the Locust nervous system. The LGMD increases its firing rate in response to both the velocity of the approaching object and its proximity. It has been found that it can respond to looming stimuli very quickly and can trigger avoidance reactions whenever a rapidly approaching object is detected. It has been successfully applied in visual collision avoidance systems for vehicles and robots. This paper proposes a modified LGMD model that provides additional movement depth direction information. The proposed model retains the simplicity of the previous neural network model, adding only a few new cells. It has been tested on both simulated and recorded video data sets. The experimental results shows that the modified model can very efficiently provide stable information on the depth direction of movement
Zoonotic Politics: The Impossible Bordering of the Leaky Boundaries of Species
Zoonotic pandemics shine an uncomfortable light on how human lifeways facilitate the sharing of pathogens across species. Yet our lack of acknowledgement of our shared vulnerability with those non-human animals we raise or hunt to kill and eat, whose habitats we encroach upon and destroy, whose populations we undermine and threaten, has led us to the current human health crisis. The predominant political response to zoonotic pandemic has been bordering practices of surveillance, securitisation and bodily separation. These practices reflect intra-human and species hierarchies. They also fail to acknowledge the extent to which the boundaries of species are leaky, and are continually breached. A posthumanist zoonotic politics seeks not to attempt to border the leaky boundaries of species, but rather to insist on a re-ordering of species relations towards less exploitative and extractive ways of sharing the planet with the myriad creatures that constitute our world
Memories of their mathematics teachers: implications for pedagogy
The future teachers in this study were asked to tell the story of their engagement withmathematics, beginning as far back as they could recall, and ending with the present whichwas as they were about to begin a module entitled Mathematical Literacy for Educators.The narratives contained accounts of their struggles (many) and successes (few) withlearning mathematics. The focus of this paper is on their memories of their mathematicsteachers who feature in most of the autobiographies. The purpose of this memory work wastwofold: to provide a starting point to overcome mathematics anxiety which had thepotential to inhibit their engagement with mathematics, and to inform the selection ofpedagogical practices in the module. Selected memory narratives are presented and thethemes of teacher memories are discussed. Finally, four pedagogical purposes for memorynarratives are identified and discussed.I've learned that people will forget what you said, people will forget what you did, butpeople will never forget how you made them feel.Maya Angelou (Kelly, 2003
Animalizing International Relations
This article explores what it means to ‘animalise’ International Relations. The posthuman move in the social sciences has involved the process of de-centring the human, replacing an anthropocentric focus with a view of the human as embedded within a complex network of inter-species relations. In a previous work we drew attention to the lack of analysis within International Relations of the key role played by more-than human animals in situations of conflict. The current COVID-19 pandemic again indicates that an analysis of international relations that does not have at its core an understating of a more than human world is always going to be an incomplete account. The paper argues for the animalizing of International Relations in order to enhance inclusivity, and suggests five ways in which this might be approached. As it becomes increasingly clear that a climate-related collapse is imminent, we argue for a transformative approach to the discipline, stressing interlinked networks and a shared vulnerability as a political project which challenges capitalism (advanced/late/carboniferous/genocidal) and the failure of states to address the concatenation of crises that life on the planet confronts
Anarchism's Posthuman Future
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the URI link.In previous work, we have argued that there are considerable areas of overlap between anarchism and complexity thinking, in particular because both explore the possibilities for the development of order without a specific source of authority. In more recent interventions we have developed a posthuman world view as a political project based on a foundation in complexity thinking. Hierarchical and exclusive forms of social organisation are usually understood by anarchists to be forms of domination. It is unsurprising then, that the history of anarchist thought and practical political engagement demonstrates a concern with an eclectic range of dominations. In this paper, we argue that in questioning our treatment of the environment, or ‘nature’ and in problematising some of our relations with non-human beings and things, some anarchism usefully informs the politics of posthumanism.
We trace the past and contemporary linkages between anarchism and posthumanist thinking, drawing on literature in the overlapping fields of political ecologism, new materialism and animal studies. However, we also argue that there is a contradiction embedded in arguments for the liberation of human and non-human beings and things and a recognition that our world was ever more-than-human. The western conception of the human as an autonomous, rational being able to make decisions and choices about actions has only developed alongside, and in contradistinction to, the ‘animal’. These conceptions of autonomy and rationality have been important to all western left political projects, including much of the politics of ecologism and anarchism, where the notion of ‘freedom’ is writ large. If anarchism is to have a posthuman future, we consider that it needs to interrogate and
perhaps loosen its ties to some established conceptual building blocks of the western political tradition
Anarchy and Anarchism: Towards a Theory of Complex International Systems
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.The use of ‘anarchy’ in International Relations theory appears very different from its incarnations in political philosophy. Whilst realist scholars have used anarchy to describe an absence of centralised political authority in which states wield differential power, political philosophers in the anarchist tradition have mounted a critique of the coercive and compulsory powers of states themselves. This article argues for reconceptualising ‘anarchy’ in International Relations theory using insights from complexity theory. We would describe the international system as a complex adaptive system which has a tendency to self-organisation. Furthermore, in distinct contrast to Waltz, we argue that the international system has to be seen as embedded within a range of physical systems, and other social systems including those which reproduce a range of (gendered, racial, class-based, colonial) relations of domination. Here insights from anarchist social ecologism can be utilised to further accounts of hierarchy and dominance within International Relations
Sensory-specific satiety and repeated exposure to novel snack foods: short- and long-term changes in food pleasantness
Sensory-specific satiety (SSS) is a significantly greater pleasantness decline for a consumed (Eaten) food, than foods that are tasted but not consumed (Uneaten). SSS occurs during consumption, reaches optimal magnitude immediately afterwards, and returns to baseline within two to three hours. The phenomenon is dependent on the sensory properties, rather than the energy or macronutrient content of the food. To the extent that an Uneaten food shares similar sensory properties with the Eaten food, the
Uneaten food may be subject to pleasantness decline: a transfer effect.
Repeated exposure to a food stimulus may alter liking in the long-term, through mere exposure, monotony, and dietary learning paradigms resulting in an association between the novel target food and either a known food stimulus, or a consequence of consumption. Novel foods are more susceptible to these effects than familiar foods, for which learned associations may have already formed. Repeated consumption alone does not modulate SSS, but to date such studies have not tested novel foods.
Through six experiments this research explores the influences of long-term pleasantness changes of novel foods and the number and type of Uneaten foods present during SSS
testing, on the magnitude of SSS for snack foods.
While no evidence of mere exposure or dietary learning was found, and in some instances experiments failed to induce SSS, these negative results are likely due to methodological, and sometimes procedural issues in the design and conduct of experimental testing. Findings revealed SSS to be vulnerable to a number of procedural
and methodological factors, such as: portion size; baseline novelty and pleasantness ratings; hunger; perceived ambiguity of measurement scales; and expectations raised by
the type and number of Uneaten foods present during testin
