In this paper we introduce a theory of policy routing dynamics based on fundamental axioms of routing update mechanisms. We develop a dynamic policy routing model (DPR) that extends the static formalism of the stable paths problem (introduced by Griffin et al.) with discrete synchronous time. DPR captures the propagation of path changes in any dynamic network irrespective of its time-varying topology. We introduce several novel structures such as causation chains, dispute fences and policy digraphs that model different aspects of routing dynamics and provide insight into how these dynamics manifest in a network. We exercise the practicality of the theoretical foundation provided by DPR with two fundamental problems: routing dynamics minimization and policy conflict detection. The dynamics minimization problem utilizes policy digraphs, that capture the dependencies in routing policies irrespective of underlying topology dynamics, to solve a graph optimization problem. This optimization problem explicitly minimizes the number of routing update messages in a dynamic network by optimally changing the path preferences of a minimal subset of nodes. The conflict detection problem, on the other hand, utilizes a theoretical result of DPR where the root cause of a causation cycle (i.e., cycle of routing update messages) can be precisely inferred as either a transient route flap or a dispute wheel (i.e., policy conflict). Using this result we develop SafetyPulse, a token-based distributed algorithm to detect policy conflicts in a dynamic network. SafetyPulse is privacy preserving, computationally efficient, and provably correct.

The Border Gateway Protocol (BGP) is the current inter-domain routing protocol used to exchange reachability information between Autonomous Systems (ASes) in the Internet. BGP supports policy-based routing which allows each AS to independently adopt a set of local policies that specify which routes it accepts and advertises from/to other networks, as well as which route it prefers when more than one route becomes available. However, independently chosen local policies may cause global conflicts, which result in protocol divergence. In this paper, we propose a new algorithm, called Adaptive Policy Management Scheme (APMS), to resolve policy conflicts in a distributed manner. Akin to distributed feedback control systems, each AS independently classifies the state of the network as either conflict-free or potentially-conflicting by observing its local history only (namely, route flaps). Based on the degree of measured conflicts (policy conflict-avoidance vs. -control mode), each AS dynamically adjusts its own path preferences—increasing its preference for observably stable paths over flapping paths. APMS also includes a mechanism to distinguish route flaps due to topology changes, so as not to confuse them with those due to policy conflicts. A correctness and convergence analysis of APMS based on the substability property of chosen paths is presented. Implementation in the SSF network simulator is performed, and simulation results for different performance metrics are presented. The metrics capture the dynamic performance (in terms of instantaneous throughput, delay, routing load, etc.) of APMS and other competing solutions, thus exposing the often neglected aspects of performance.

The threat posed by the crisis in Mali is direct, multidimensional and without regard to geographical proximity or historical and colonial heritage, writes Giovanni Faleg. France’s solitary intervention in Mali and the EU’s absence there raise two important questions for the future of the EU’s supposedly ‘Common’ Security and Defence Policy. The first has to do with the crisis itself; its nature and the threat posed by the terrorist groups and militias that are being countered by French armed forces. The second concerns the causes and implications of yet another example of the EU’s inability to take responsibility for security matters in its neighbourhood and beyond.

The EU has not been perceived as reacting very rapidly or effectively to the so-called Arab Spring. Events do appear to validate the idea underpinning the European Security Strategy (ESS) and the European Neighbourhood Policy (ENP): only where governments guarantee to their citizens security, prosperity, freedom and equality, can peace and stability last – otherwise, people will revolt. But in practice, in its southern neighbourhood the EU has acted in precisely the opposite manner, so the Arab Spring is occurring in spite of rather than thanks to EU policy. The ENP stands at a crossroads therefore: Can a new start be made? Which instruments and, in times of austerity, which means can the EU apply to consolidate democratization? And, finally, can the EU continue to wage an ENP without addressing the hard security dimension, especially as the US seem to be withdrawing from crisis management in the region – or shall it continue to leave that to others?

O propósito da tese é analisar em que circunstâncias presidentes brasileiros recorrem a mecanismos de controle político sobre a burocracia pública. O argumento central é que o recurso presidencial a nomeações políticas, decretos regulamentares detalhados e criação de órgãos públicos centralizados na Presidência deverá variar em função de fatores políticos e características das coalizões de governo. Por meio de nomeações políticas, presidentes podem monitorar o comportamento de servidores públicos sob a influência indesejada de ministros do gabinete. Com decretos regulamentares detalhados podem reduzir a autonomia decisória de servidores públicos na interpretação de leis vagas. Por fim, por meio da criação de órgãos públicos centralizados na Presidência, podem gerar condições mais favoráveis ao futuro controle da burocracia pública. O propósito da tese será desdobrado em três problemas de pesquisa, com desenhos orientados para variáveis. O primeiro, desenvolvido no primeiro capítulo, aborda como a heterogeneidade política da coalizão afeta o controle presidencial sobre a burocracia pública por meio de nomeações políticas. O segundo problema, discutido no capítulo seguinte, analisa como a rotatividade ministerial e a demanda pela implementação interministerial de uma mesma lei afetam o grau de detalhamento de decretos regulamentares. Por fim, o terceiro problema de pesquisa, abordado no último capítulo, avalia como a composição heterogênea dos gabinetes afeta a criação de burocracias centralizadas na Presidência da República. Por meio de métodos estatísticos, foram estimados modelos de regressão linear multivariada a fim de analisar os determinantes 1. das nomeações políticas e 2. do grau de detalhamento dos decretos regulamentares, bem como modelos de regressão logística binária para avaliar a probabilidade de centralização presidencial na criação de órgãos públicos. A politização da burocracia federal tende a aumentar quando o conflito entre parceiros da coalizão é maior, uma alternativa presidencial às orientações ministeriais indesejadas sobre a burocracia pública. Decretos regulamentares tendem a ser mais detalhados quando ministérios são mais voláteis e quando há implementação interministerial, uma alternativa presidencial à autonomia da burocracia pública. Por fim, a centralização tende a crescer quando o conflito de políticas entre presidente e ministros é maior, uma saída às orientações ministeriais nocivas às preferências do presidente.

Since 2000, the number of living wage ordinances has steadily increased throughout the country. While most of the current research has focused on the beneficial outcomes of living wages, little has been published on their administrative practices. To address this shortcoming, this study focused on the identification of key administrative and political factors involved impacting the implementation of living wage ordinances in Miami-Dade and Broward Counties. The study utilized a triangulation of interviews, surveys, and direct observation. The author conducted interviews of administrators and members of the living wage oversight boards in both counties and observed the monthly meetings held by each county’s oversight board from January 2006 to June 2007. These findings were buttressed with a national survey of senior staff in other living wage communities. The study utilized descriptive statistics, Chi Square, Cronbach’s Alpha, and Spearman’s Rank Correlation Coefficient (Spearman’s rho). Interviews indicated that administrators in Dade and Broward are seriously under-staffed and budgeted. Ambiguities in the enabling ordinances have lead to loopholes that undermine implementation and accountability for participating contractors. Survey results showed that policy ambiguity, organizational politics, and a lack of organizational capacity were significant negative factors in the implementation process while an organizational culture emphasizing consistent enforcement was a positive factor. Without the proper inputs, an organization hinders itself from meeting its outputs and outcomes. This study finds that Broward and Miami-Dade Counties do not provide the necessary administrative support to implement a living wage effectively – in stark contrast to the high hopes and strong political support behind their passage. For a living wage to succeed, it first needs an organizational culture committed to providing the necessary resources for implementation as well as transparent, consistent accountability mechanisms.

Land use planning within and surrounding privatised Australian capital city airports is a fragmented process as a result of: current legislative and policy frameworks; competing stakeholder priorities and interests; and inadequate coordination and disjointed decision-making. Three Australian case studies are examined to detail the context of airport and regional land use planning. Stakeholder Land Use Forums within each case study have served to inform the procedural dynamics and relationships between airport and regional land use decision-making. This article identifies significant themes and stakeholder perspectives regarding on-airport development and broader urban land use policy and planning. First, it outlines the concept of the “airport city” and examines the model of airport and regional “interfaces.” Then, it details the policy context that differentiates on-airport land use planning from planning within the surrounding region. The article then analyses the results of the Land Use Forums identifying key themes within the shared and reciprocal interfaces of governance, environment, economic development and infrastructure. The article concludes by detailing the implications of this research to broader urban planning and highlights the core issues contributing to the fragmentation of airport and regional land use planning policy.

Perhaps the weakest dimension of the ‘triple bottom line’ understanding of
sustainable development has been the ‘economic’ dimension. Much of the thinking
about the appropriate ‘political economy’ to underpin sustainable development has
been either utopian (as in some ‘environmental’ political views) or ‘business as usual’ approaches. Rejecting both of these utopian and realist views, it is clear from the papers presented here and the conference debates that something like ‘ecological modernisation’ is the preferred conceptualisation of ‘sustainable development’ within policy circles in Northern Ireland, the UK and other European states.

In the aftermath of the Irish revolution and Civil War the governments of independent Ireland introduced various compensation schemes to provide financial reintegration assistance to revolutionary veterans. This would be recognised today as part of a programme for DDR. This paper will examine various service and disability pensions paid to veterans in the context of literature on post-conflict reintegration. It will examine various challenges to reintegration in an effort to analyse the success of revolutionary compensation as a post-conflict reintegration mechanism in independent Ireland after 1922.
