The death of Osama bin Laden - the end of Al-Qaeda's Pan-Islamic ambition?

This paper evaluates the implications of Osama bin Ladin’s death for the future of al-Qaeda’s global jihad. It critically examines the debate as to the make-up of the group and identifies bin Ladin’s primary role as chief ideologue advocating a defensive jihad to liberate the umma. The rationale and appeal of bin Ladin’s message and Muslims’ reaction to both his statements and al-Qaeda’s increasing use of sectarian violence are assessed in the context of Pan-Islam as political ideology. The paper concludes that while the ideal of Islamic unity and the sentiment of Muslim solidarity are unlikely to vanish, al-Qaeda’s violent jihad has not only failed to achieve these goals but has worked against it, thereby confining it to the political margins.

The death of John Stuart Mill

This article surveys the fiercely contested posthumous assessments of John Stuart Mill in the newspaper and periodical press, in the months following his death in May 1873, and elicits the broader intellectual context. Judgements made in the immediate wake of Mill's death influence biographers and historians to this day and provide an illuminating aperture into the politics and shifting ideological forces of the period. The article considers how Mill's failure to control his posthumous reputation demonstrates both the inextricable intertwining of politics and character in the 1870s, and the difficulties his allies faced. In particular, it shows the sharp division between Mill's middle and working class admirers; the use of James Mill's name as a rebuke to his son; the redefinition of Malthusianism in the 1870s; and how publication of Mill's Autobiography damaged his reputation. Finally, the article considers the relative absence of both theological and Darwinian critiques of Mill.

A study of cursor trajectories of motion-impaired users

This paper describes a study of the cursor trajectories of motion-impaired users in "point and click" interactions. A characteristic of cursor movement is proposed that aims to capture the spatial distribution of cursor movement about a target. This characteristic indicates that users often exhibit increased cursor movement in the vicinity of the target, have more difficulty performing the "clicking" part of the interaction as compared to the navigation part, and tend to navigate directly toward the target during the middle portion of the cursor trajectory. The implications of these characteristic behaviours on interface design are discussed.

Optimal linearization trajectories for tangent linear models

We examine differential equations where nonlinearity is a result of the advection part of the total derivative or the use of quadratic algebraic constraints between state variables (such as the ideal gas law). We show that these types of nonlinearity can be accounted for in the tangent linear model by a suitable choice of the linearization trajectory. Using this optimal linearization trajectory, we show that the tangent linear model can be used to reproduce the exact nonlinear error growth of perturbations for more than 200 days in a quasi-geostrophic model and more than (the equivalent of) 150 days in the Lorenz 96 model. We introduce an iterative method, purely based on tangent linear integrations, that converges to this optimal linearization trajectory. The main conclusion from this article is that this iterative method can be used to account for nonlinearity in estimation problems without using the nonlinear model. We demonstrate this by performing forecast sensitivity experiments in the Lorenz 96 model and show that we are able to estimate analysis increments that improve the two-day forecast using only four backward integrations with the tangent linear model.

Writing, death and absence in 'Tim' by H.O. Sturgis

There has been a considerable critical interest in the representation of death in Children's Literature, with an increasingly prevalent move to read it as granting the child the status of object. Thus, for example, Judith Plotz takes it to 'increase [the] presence' of the child. Through a detailed reading of one late C19th school story, I suggest that such readings proceed through a resistance to textuality. This essay offers a reading of death as bound up with the play of the text, deferred, shifting and retrospectively constructed rather than a state of simple, recoverable objecthood.

Communication and social regulation. the criminalization of work-related death

This paper addresses the movement towards criminalization as a tool for the regulation of work-related deaths in the United Kingdom and elsewhere in the last 20 years. This can be seen as reflecting dissatisfaction with the relevant law, although it is best understood in symbolic terms as a response to a disjunction between the instrumental nature and communicative aspirations of regulatory law. This paper uses empirical data gathered from interviews with members of the public to explore the role that such an offence might play. The findings demonstrate that the failures of regulatory law give rise to a desire for criminalization as a means of framing work-related safety events in normative terms.

GTP binding and intramolecular regulation by the ROC domain of Death Associated Protein Kinase 1

The ROCO proteins are a family of large, multidomain proteins characterised by the presence of a Ras of complex proteins (ROC) domain followed by a COR, or C-terminal of ROC, domain. It has previously been shown that the ROC domain of the human ROCO protein Leucine Rich Repeat Kinase 2 (LRRK2) controls its kinase activity. Here, the ability of the ROC domain of another human ROCO protein, Death Associated Protein Kinase 1 (DAPK1), to bind GTP and control its kinase activity has been evaluated. In contrast to LRRK2, loss of GTP binding by DAPK1 does not result in loss of kinase activity, instead acting to modulate this activity. These data highlight the ROC domain of DAPK1 as a target for modifiers of this proteins function, and casts light on the role of ROC domains as intramolecular regulators in complex proteins with implications for a broad range of human diseases.

Reframing 'crisis' in fair trade coffee production: trajectories of agrarian change in Nicaragua

A focus on crisis provides a methodological window to understand how agrarian change shapes producer engagement in fair trade. This orientation challenges a seperation between the market and development, situating fair trade within global processes that incorporate agrarian histories of social change and conflict. Reframing crisis as a condition of agrarian life, rather than emphasizing its cyclical manifestation within the global economy, reveals how market-driven development encompasses the material conditions of peoples' existence in ambiguous and contradictory ways. Drawing on the case of coffee production in Nicaragua, experiences of crisis demonstrate that greater attention needs to be paid to the socioeconomic and political dimensions of development within regional commodity assemblages to address entrenched power relations and unequal access to land and resources. This questions moral certainties when examining the paradox of working in and against the market, and suggests that a better understanding of specific trajectories of development could improve fair trade's objective of enhancing producer livelihoods.

Rigid body trajectories in different 6D spaces

The objective of this paper is to show that the group SE(3) with an imposed Lie-Poisson structure can be used to determine the trajectory in a spatial frame of a rigid body in Euclidean space. Identical results for the trajectory are obtained in spherical and hyperbolic space by scaling the linear displacements appropriately since the influence of the moments of inertia on the trajectories tends to zero as the scaling factor increases. The semidirect product of the linear and rotational motions gives the trajectory from a body frame perspective. It is shown that this cannot be used to determine the trajectory in the spatial frame. The body frame trajectory is thus independent of the velocity coupling. In addition, it is shown that the analysis can be greatly simplified by aligning the axes of the spatial frame with the axis of symmetry which is unchanging for a natural system with no forces and rotation about an axis of symmetry.
