This article analyzes the role of the European Union (EU) and Canada in the promotion of Security Sector Reforms (SSR) activities in two regional organizations, the Organization for Security and Cooperation in Europe (OSCE) and the North Atlantic Treaty Organization (NATO). The concept of SSR seeks to address the effective governance of security in post-conflict environment by transforming the security institutions within a country in order for them to have more efficient, legitimate and democratic role in implementing security. Recent debates within the EU have led to the adoption of an SSR concept from the Council and a new strategy from the European Commission on the SSR activities. Within the framework of the ESDP, the EU has positioned itself as a leading actor, in this domain, including in its crisis management operations. On the other hand, Canada, through its whole-of government and human security programs has also been an important actor in the promotion of SSR activities. Yet, even though several international organizations (including the United Nations, the OSCE and NATO) are effectively doing SSR activities on the ground, there does not exist a common framework within any of these organizations despite the role of the EU and Canada. As such, it is surprising to found no global common policy for SSR while this approach is precisely holistic in its foundations. Taking these elements into consideration, this paper analyzes two specific aspects : a) the absence of a common policy framework within international organizations and b) the major differences between the approaches of the OSCE and NATO in the domain of SSR and the implications for the EU and Canada’ roles.   Full extt available at: https://doi.org/10.22215/rera.v3i2.186

Visas are specifically aimed at controlling admission at the stage of pre-departure and constitute one of the essential requirements for entry under the Schengen Borders Code. This chapter examines the common policy of the EU, conceptualizing them as pre-authorizations of entry granted before arrival in the territory of the Member States. Visa requirements, as introduced in the Visa Regulation, are perused at the outset, taking account of periodic revisions of the visa lists and the criteria for amendment considered relevant by the EU legislator. The key features of the uniform visa format and the Visa Information System (VIS) are briefly presented, highlighting their contribution to the securitisation of migration flows. Then, the visa issuing procedure, as governed by the Community Code on Visas (CCV), is examined. The final section is reserved to the analysis of the implications of the different components of the policy regarding access to asylum in the Member States.

Abstract We propose a fully distributed actor-critic architecture, named diffusion-distributed-actor-critic Diff-DAC, with application to multitask reinforcement learning (MRL). During the learning process, agents communicate their value and policy parameters to their neighbours, diffusing the information across a network of agents with no need for a central station. Each agent can only access data from its local task, but aims to learn a common policy that performs well for the whole set of tasks. The architecture is scalable, since the computational and communication cost per agent depends on the number of neighbours rather than the overall number of agents. We derive Diff-DAC from duality theory and provide novel insights into the actor-critic framework, showing that it is actually an instance of the dual-ascent method. We prove almost sure convergence of Diff-DAC to a common policy under general assumptions that hold even for deep neural network approximations. For more restrictive assumptions, we also prove that this common policy is a stationary point of an approximation of the original problem. Numerical results on multitask extensions of common continuous control benchmarks demonstrate that Diff-DAC stabilises learning and has a regularising effect that induces higher performance and better generalisation properties than previous architectures.

One of the most common policy-related messages that economists present to non-economists is the superiority of cash over in-kind transfers as a policy tool. A good deal of government policy on behalf of the poor consists, of course, of various forms of in-kind assistance, such as medical care or food stamps. However, if we wish to help the poor, the argument goes, in-kind transfers are an inferior way to do so.
