Political corruption in the Caribbean Basin retards state economic growth and development, undermines government legitimacy, and threatens state security. In spite of recent anti-corruption efforts of intergovernmental and nongovernmental organizations (IGO/NGOs), Caribbean political corruption problems appear to be worsening in the post-Cold War period. This dissertation discovers why IGO/NGO efforts to arrest corruption are failing by investigating the domestic and international causes of political corruption in the Caribbean. The dissertation's theoretical framework centers on an interdisciplinary model of the causes of political corruption built within the rule-oriented constructivist approach to social science. The model first employs a rational choice analysis that broadly explains the varying levels of political corruption found across the region. The constructivist theory of social rules is then used to develop the structural mechanisms that further explain the region's levels of political corruption. The dissertation advances its theory of the causes of political corruption through qualitative disciplined-configurative case studies of political corruption in Jamaica and Costa Rica. The dissertation finds that IGO/NGO sponsored anti-corruption programs are failing because they employ only technical measures (issuing anti-corruption laws and regulations, providing transparency in accounting procedures, improving freedom of the press, establishing electoral reforms, etc.). While these IGO/NGO technical measures are necessary, they are not sufficient to arrest the Caribbean's political corruption problems. This dissertation concludes that to be successful, IGO/NGO anti-corruption programs must also include social measures, e.g., building civil societies and modernizing political cultures, for there to be any hope of lowering political corruption levels and improving Caribbean social conditions. The dissertation also highlights the key role of Caribbean governing elite in constructing the political and economic structures that cause their states' political corruption problems. ^

Using the link-link incidence matrix to represent a simple-jointed kinematic chain algebraic procedures have been developed to determine its structural characteristics such as the type of freedom of the chain, the number of distinct mechanisms and driving mechanisms that can be derived from the chain. A computer program incorporating these graph theory based procedures has been applied successfully for the structural analysis of several typical chains.

This article analyses support for censorship in Russia as part of the democratization process. Censorship has been an important part of Russian history and it was strengthened during the Soviet era. After the collapse of the Soviet system formal censorship was banned even though the reality has been different. Therefore it is not strange that many Russians would like to limit the freedom of the media and to censor certain topics. The views of Russians on censorship have been studied on the basis of a survey carried out in 2007. According to the results, three different dimensions of censorship were found. These dimensions include moral censorship, political censorship, and censorship of religious materials. Support for these dimensions varies on the basis of socio-demographic characteristics and media use. The article concludes that many Russians reject new phenomena, while support for the censorship of political criticism is not as high, but political censorship seems to enjoy more support among elites than among the common people.

Justice as Improvisation: The Law of the Extempore theorises the relationship between justice and improvisation through the case of the New York City cabaret laws. Discourses around improvisation often imprison it in a quasi-ethical relationship with the authentic, singular ‘other’. The same can be said of justice. This book interrogates this relationship by highlighting the parallels between the aporetic conception of justice advanced by the late French philosopher Jacques Derrida and the nuanced approach to improvisation pursued by musicians and theorists alike in the new and emerging interdisciplinary field of Critical Studies in Improvisation (CSI). Justice as Improvisation re-imagines justice as a species of improvisation through the formal structure of the most basic of legal mechanisms, judicial decision-making, offering law and legal theory a richer, more concrete, understanding of justice. Not further mystery or mystique, but a negotiation between abstract notions of justice and the everyday practice of judging. Improvisation in judgment calls for ongoing, practical decision-making as the constant negotiation between the freedom of the judge to take account of the otherness or singularity of the case and the existing laws or rules that both allow for and constrain that freedom. Yes, it is necessary to judge, yes, it is necessary to decide, but to judge well, to decide justly, that is a music lesson perhaps best taught by critical improvisation scholars.

An automatic nonlinear predictive model-construction algorithm is introduced based on forward regression and the predicted-residual-sums-of-squares (PRESS) statistic. The proposed algorithm is based on the fundamental concept of evaluating a model's generalisation capability through crossvalidation. This is achieved by using the PRESS statistic as a cost function to optimise model structure. In particular, the proposed algorithm is developed with the aim of achieving computational efficiency, such that the computational effort, which would usually be extensive in the computation of the PRESS statistic, is reduced or minimised. The computation of PRESS is simplified by avoiding a matrix inversion through the use of the orthogonalisation procedure inherent in forward regression, and is further reduced significantly by the introduction of a forward-recursive formula. Based on the properties of the PRESS statistic, the proposed algorithm can achieve a fully automated procedure without resort to any other validation data set for iterative model evaluation. Numerical examples are used to demonstrate the efficacy of the algorithm.

A multitude of views characterize what should or should not be done about climate change, and in the past decades, nations have acted very differently in the face of climate change. This study explores factors that affect individuals' attitudes and concerns towards the environment and how those attitudes ultimately affect climate change policy. One model investigates the link between individual attitudes and countries' actions on climate change, and the results show that attitudes indeed matter in the implementation of policy. Different measures of democracy such as freedom of the press also prove to be important as channels for these attitudes. A second model identifies a number of political, socioeconomic and demographic characteristics that matter for people's attitudes towards climate change.

Simulating surface wind over complex terrain is a challenge in regional climate modelling. Therefore, this study aims at identifying a set-up of the Weather Research and Forecasting Model (WRF) model that minimises system- atic errors of surface winds in hindcast simulations. Major factors of the model configuration are tested to find a suitable set-up: the horizontal resolution, the planetary boundary layer (PBL) parameterisation scheme and the way the WRF is nested to the driving data set. Hence, a number of sensitivity simulations at a spatial resolution of 2 km are carried out and compared to observations. Given the importance of wind storms, the analysis is based on case studies of 24 historical wind storms that caused great economic damage in Switzerland. Each of these events is downscaled using eight different model set-ups, but sharing the same driving data set. The results show that the lack of representation of the unresolved topography leads to a general overestimation of wind speed in WRF. However, this bias can be substantially reduced by using a PBL scheme that explicitly considers the effects of non-resolved topography, which also improves the spatial structure of wind speed over Switzerland. The wind direction, although generally well reproduced, is not very sensitive to the PBL scheme. Further sensitivity tests include four types of nesting methods: nesting only at the boundaries of the outermost domain, analysis nudging, spectral nudging, and the so-called re-forecast method, where the simulation is frequently restarted. These simulations show that restricting the freedom of the model to develop large-scale disturbances slightly increases the temporal agreement with the observations, at the same time that it further reduces the overestimation of wind speed, especially for maximum wind peaks. The model performance is also evaluated in the outermost domains, where the resolution is coarser. The results demonstrate the important role of horizontal resolution, where the step from 6 to 2 km significantly improves model performance. In summary, the combination of a grid size of 2 km, the non-local PBL scheme modified to explicitly account for non-resolved orography, as well as analysis or spectral nudging, is a superior combination when dynamical downscaling is aimed at reproducing real wind fields.

Although the catalytic (C) subunit of cAMP-dependent protein kinase is N-myristylated, it is a soluble protein, and no physiological role has been identified for its myristyl moiety. To determine whether the interaction of the two regulatory (R) subunit isoforms (RI and RII) with the N-myristylated C subunit affects its ability to target membranes, the effect of N-myristylation and the RI and RII subunit isoforms on C subunit binding to phosphatidylcholine/phosphatidylserine liposomes was examined. Only the combination of N-myristylation and RII subunit interaction produced a dramatic increase in the rate of liposomal binding. To assess whether the RII subunit also increased the conformational flexibility of the C subunit N terminus, the effect of N-myristylation and the RI and RII subunits on the rotational freedom of the C subunit N terminus was measured. Specifically, fluorescein maleimide was conjugated to Cys-16 in the N-terminal domain of a K16C mutant of the C subunit, and the time-resolved emission anisotropy was determined. The interaction of the RII subunit, but not the RI subunit, significantly increased the backbone flexibility around the site of mutation and labeling, strongly suggesting that RII subunit binding to the myristylated C subunit induced a unique conformation of the C subunit that is associated with an increase in both the N-terminal flexibility and the exposure of the N-myristate. RII subunit thus appears to serve as an intermolecular switch that disrupts of the link between the N-terminal and core catalytic domains of the C subunit to expose the N-myristate and poise the holoenzyme for interaction with membranes.

In the last 30 years, a clear trend has come to define modern immigration law and policy. A set of seemingly disparate developments concerning the constant reinforcement of border controls, tightening of conditions of entry, expanding capacities for detention and deportation and the proliferation of criminal sanctions for migration offences, accompanied by an anxiety on the part of the press, public and political establishment regarding migrant criminality can now be seen to form a definitive shift in the European Union towards the so-called ‘criminalisation of migration’. This paper aims to provide an overview of the ‘state-of-the-art’ in the academic literature and EU research on criminalisation of migration in Europe. It analyses three key manifestations of the so-called ‘crimmigration’ trend: discursive criminalisation; the use of criminal law for migration management; and immigrant detention, focusing both on developments in domestic legislation of EU member states but also the increasing conflation of mobility, crime and security which has accompanied EU integration. By identifying the trends, synergies and gaps in the scholarly approaches dealing with the criminalisation of migration, the paper seeks to provide a framework for on-going research under Work Package 8 of the FIDUCIA project.
