Synchronization in Networks of Hindmarsh-Rose Neurons
No full textSynchronization is deemed to play an important role in information processing in many neuronal systems. In this work, using a well known technique due to Pecora and Carroll, we investigate the existence of a synchronous state and the bifurcation diagram of a network of synaptically coupled neurons described by the Hindmarsh-Rose model. Through the analysis of the bifurcation diagram, the different dynamics of the possible synchronous states are evidenced. Furthermore, the influence of the topology on the synchronization properties of the network is shown through an exampl
Genetic testing: A threat to privacy
No full textThis chapter summarises some of the problems associated with privacy and genetic information in the medical context of genetic testing. It outlines some of the major reasons why legislation is needed to protect our genetic privacy. The chapter suggests that legislation is needed to protect medical records; address the sharing of genetic information and the consent process; prohibit the collection or analysis of genetic samples without consent; and, guide and protect the collection, storage, access and destruction of genetic information
Consumer views of organic and GM food
No full textAttitudes towards food, and decisions about eating, are mediated within a complex political and cultural milieu. With food a biological necessity, decisions about what to eat are instead shaped by a complex range of values and beliefs about ourselves, the risks and pleasures associated with eating, and understandings of our relationships with others and the environment. In recent years a plethora of food scares, ranging from salmonella to chemical residues and bovine spongiform encephalopathy (mad cow disease), have intensified awareness of the vulnerability of humans to sickness, and in some cases death, from eathing the wrong foods. Eating patterns - particularly the rapid growth in consumption of organic and chemical-free food in the developed world - thus tell us about more than anxieties related to personal health and perceived risks associated with industrially produced foods: they also reflect concerns about broader environmental, social and economic implications of food consumption practices. In this chapter we overview the recent rapid growth in the organic food and agriculture sector, with a particular focus upon Australia. This growth has been driven, in large part, by an apparently insatiable consumer demand for organic food. Expansion in organics, though, has occurred alongside substantial investment in food biotechnology research and development (R&D). While proponents of organics argue that organic farming methods will be an integral part of the shift towards a truly sustainable system of agriculture, critics suggest that sustainability will not be possible without biotechnological innovations and their application to food and agriculture. In examining Australian consumers' attitudes to both organic and genetically engineered food, and their contributions towards sustainable agriculture, this chapter also dispels the assumptions of organics consumers as just yuppies, greenies and health nuts. We explore the values and beliefs of organic food consumers, and highlight similarities and differences between these and those of non-organic food consumers. From this analysis, it is apparent that widespread opposition exists among most Australians to the entry of genetically modified (GM) food into the food system. As a consequence of this opposition - and the belief among many that consumption of organic food offers a meaningful alternative - we can expect a continued expansion of the organics industry. Before examining Australian consumer views, we survey the competing visions for the future of food production in Australia
Synchronization of diffusively coupled electronic Hindmarsh-Rose oscillators
No full textIn this paper we study the synchronization of diffusively coupled Hindmarsh-Rose (HR) electronic oscillators. These electronic oscillators are analog electrical circuits which integrate the differential equations of the HR model. An experimental setup consisting of four chaotic HR oscillators, is used to evaluate the existence and stability of partially or fully synchronized states

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
