The Great appropriation: Political Possibilities Since 1974

Argued that a new cadre of 'intellectual journalists' (such as Paul Kelly), unlike scholars of Graham Maddox's standing, have usurped critical appraisals of the possibilities of politics. This new anti-democratic liberalism wrongly suggests that political achievements reached when Australia was less rich (such as compulsory industrial arbitration) now need to abandoned, subordinating national well-being to an international policy orthodoxy.

Identification of residues and domains of Raf important for function in vivo and in vitro

Random mutagenesis and genetic screens for impaired Raf function in Caenorhabditis elegans were used to identify six loss-of-function alleles of lin-45 raf that result in a substitution of a single amino acid. The mutations were classified as weak, intermediate, and strong based on phenotypic severity. We engineered these mutations into the homologous residues of vertebrate Raf-1 and analyzed the mutant proteins for their underlying biochemical defects. Surprisingly, phenotype strength did not correlate with the catalytic activity of the mutant proteins. Amino acid substitutions Val-589 and Ser-619 severely compromised Raf kinase activity, yet these mutants displayed weak phenotypes in the genetic screen. Interestingly, this is because these mutant Raf proteins efficiently activate the MAPK (mitogen-activated protein kinase) cascade in living cells, a result that may inform the analysis of knockout mice. Equally intriguing was the observation that mutant proteins with non-functional Ras-binding domains, and thereby deficient in Ras-mediated membrane recruitment, displayed only intermediate strength phenotypes. This confirms that secondary mechanisms exist to couple Ras to Raf in vivo. The strongest phenotype in the genetic screens was displayed by a S508N mutation that again did not correlate with a significant loss of kinase activity or membrane recruitment by oncogenic Ras in biochemical assays. Ser-508 lies within the Raf-1 activation loop, and mutation of this residue in Raf-1 and the equivalent Ser-615 in B-Raf revealed that this residue regulates Raf binding to MEK. Further characterization revealed that in response to activation by epidermal growth factor, the Raf-S508N mutant protein displayed both reduced catalytic activity and aberrant activation kinetics: characteristics that may explain the C. elegans phenotype.

Politicization of non-political events

Spatial analysis and social network analysis typically take into consideration social processes in specific contexts of geographical or network space. The research in political science increasingly strives to model heterogeneity and spatial dependence. To better understand and geographically model the relationship between “non-political” events, streaming data from social networks, and political climate was the primary objective of the current study. Geographic information systems (GIS) are useful tools in the organization and analysis of streaming data from social networks. In this study, geographical and statistical analysis were combined in order to define the temporal and spatial nature of the data eminating from the popular social network Twitter during the 2014 FIFA World Cup. The study spans the entire globe because Twitter’s geotagging function, the fundamental data that makes this study possible, is not limited to a geographic area. By examining the public reactions to an inherenlty non-political event, this study serves to illuminate broader questions about social behavior and spatial dependence. From a practical perspective, the analyses demonstrate how the discussion of political topics fluсtuate according to football matches. Tableau and Rapidminer, in addition to a set basic statistical methods, were applied to find patterns in the social behavior in space and time in different geographic regions. It was found some insight into the relationship between an ostensibly non-political event – the World Cup - and public opinion transmitted by social media. The methodology could serve as a prototype for future studies and guide policy makers in governmental and non-governmental organizations in gauging the public opinion in certain geographic locations.

External and internal dynamics in the EU's counter-terrorism policy: a political and legal analysis

Tese de Doutoramento em Ciência Política e Relações Internacionais

Sujeto y Política. La constitución de las identidades desde una perspectiva postfundacionalista: hacia la construcción de un marco teórico-metodológico para el análisis histórico-político. Subject and politics. The constitution of political identities from a posfoundational perspective: towards a construction of a theorethico-methodolocal framework for histórico-political analysis.

El proyecto de investigación se dirige a sistematizar un abordaje postfundacionalista de las identidades políticas en vistas a la construcción de un marco teórico-metodológico para el análisis histórico-político. Se parte de la creciente relevancia en las ciencias sociales de la cuestión de la “identidad” para indagar la singularidad del marco teórico adoptado en su estudio. Así, el postfundacionalismo da cuenta de una teoría de las subjetividades políticas que parte de procesos de identificación que suponen una articulación singular entre relativa estructuralidad y agencia. El sujeto emerge en un contexto nunca plenamente suturado ni plenamente abierto, sino a través de un anudamiento de diversas dimensiones reales, simbólicas e imaginarias. Esta visión es altamente productiva para generar conclusiones relevantes en el campo de la ciencia política y del análisis histórico político comparado. This research project seeks to systematise from a postfundationalist view of political identities a theoretico-methodological framework for historico political analysis. The project starts from the increasing relevance of the quistion of 'identity' for contremporary social sciences. Poststructuralism provides an insight of processes of identification that supposes a singular articulation between relative structurality and agency. The subject emerges in a neither fully structured nor fully opened context but through a knotting process of different registers: real, symblic and imaginary. This vision, we believe, is highly productive to generate meaningful conclusions in the field of political science and comparative political analysis.
