Fiscal Rules for Subnational Governments. Some organizing principles and Latin American experiences
In this paper we investigate the logic and the workings of fiscal rules, with focus on rules for subnational governments. We argue against a simplistic view that sees the writing of numerical limits on fiscal variables as the solution to fundamental fiscal problems. We suggest that international organizations should take a more comprehensive approach when dealing with the fiscal problems of developing countries. Such an approach requires a deep understanding of the determinants of undesirable fiscal outcomes in each particular case, which in turn requires some explicit political analysis.fiscal rules, fiscal policy
Towards Effective Social Insurance in Latin America: The Importance of Countercyclical Fiscal Policy
Latin America is a volatile, crisis-prone region, with limited and inadequate social insurance. Therefore, the long-term as well as the recent poor suffer significantly during crises. Furthermore, social spending is procyclical in the region, but less so than total spending, indicating that the effectiveness of compensatory social policies designed to protect those vulnerable to crises is constrained by adjustments during recessions. The causes of procyclical fiscal policy lie in the political constraints on saving during expansions, combined with limited creditworthiness during recessions, and enhanced by economic volatility and a low share of automatic stabilizers in the budget.

We evaluate policy options to reduce procyclicality of fiscal policy, such as stabilization funds, fiscal rules and reform of budget institutions, and argue in favor of integrated policy proposals based on more country-specific analysis, such as the Fiscal Responsibility Law in Brazil.
A checklist for choosing between R packages in ecology and evolution
The open source and free programming language R is a phenomenal mechanism to address a multiplicity of challenges in ecology and evolution. It is also a complex ecosystem because of the diversity of solutions available to the analyst.
Packages for R enhance and specialize the capacity to explore both niche data/experiments and more common needs. However, the paradox of choice or how we select between many seemingly similar options can be overwhelming and lead to different potential outcomes.
There is extensive choice in ecology and evolution between packages for both fundamental statistics and for more specialized domainâlevel analyses.
Here, we provide a checklist to inform these decisions based on the principles of resilience, need, and integration with scientific workflows for evidence.
It is important to explore choices in any analytical coding environmentânot just Râfor solutions to challenges in ecology and evolution, and document this process because it advances reproducible science, promotes a deeper understand of the scientific evidence, and ensures that the outcomes are correct, representative, and robust.York University Librarie

Who Decides on Public Expenditures? A Political Economy Analysis of the Budget Process: The Case of Argentina
The budget process is increasingly considered key for reform efforts to improve fiscal outcomes. In this paper we embark on a political economy analysis of the budget process in Argentina, in the spirit of the IDB project âPolitical Institutions, Policymaking Processes and Policy Outcomesâ in order to understand who determines budget outcomes in Argentina. In particular, we seek to characterize the institutional framework that regulates the budget preparation, approval, implementation and control. Furthermore, we identify which actors are involved both formally and informally in the process at each stage, and seek to understand their incentives and interactions. We find that the President has a de facto role that is much more powerful than what the laws and institutions of the budget process stipulate. However, the rigidity of the budget process, together with other constraints such as macroeconomic shocks, fiscal rules, agreements with International Financial Institutions (IFIs) and the influence of other actors such as governors, legislators and lobbies - have limited the ability of the Executive to substantially modify the budget process. Furthermore, compared with the period of high inflation of 1983-1991, in the past decade we have witnessed dramatic improvements in the institutionalization of the budget process, both in political and administrative terms. These reforms have accompanied a strong improvement in fiscal outcomes in the 1990s compared with the 1980s, and provided some of the tools necessary to limit the depth of the recent crisis and regain macroeconomic stability.
Surfactant induced smooth and symmetric interfaces in Cu/Co multilayers
In this work we studied Ag surfactant induced growth of Cu/Co multilayers.
The Cu/Co multilayers were deposited using Ag surfactant by ion beam sputtering
technique. It was found that Ag surfactant balances the asymmetry between the
surface free energy of Cu and Co. As a result, the Co-on-Cu and Cu-on-Co
interfaces become sharp and symmetric and thereby improve the thermal stability
of the multilayer. On the basis of obtained results, a mechanism leading to
symmetric and stable interfaces in Cu/Co multilayers is discussed.Comment: 7 Pages, 7 Figure
Design and practical deployment of a network-centric remotely piloted aircraft system
Remotely piloted aircraft systems (RPASs) are gaining more are more relevance during the last decade since more applications are being enabled by lighter planes with increasing autonomy, higher ceilings, and more powerful transmission technologies. The integration of the RPAS as part of network-centric warfare would be a very important milestone to achieve because of the huge amount of information and capabilities that all these aircrafts can incorporate into the global scheme. This integration is easier for handheld (short-range) RPASs since their communications are typically based on digital transmission like WiFi or WiMAX, but it may not be as obvious for bigger RPASs (long-range, e.g., tactical or medium/high altitude systems) because their line of sight communications are frequently based on analog transmissions. This implies indirect integration into network-centric warfare by means of the ground control station (satellite communications, when available, may suffer notorious delay for certain applications). This article presents a recent practical experience, including flight test campaigns, deploying an all- IP communication architecture into one of the most relevant Spanish tactical RPASs, the SIVA, used by both the Spanish Army and the Spanish Air Force for the last 10 years. This deployment enables cost-effective integration of this RPAS (and its natural successor, the MILANO, a medium- altitude RPAS) into the network-centric warfare by means of direct TCP/IP transmissions over a long-range digital line of sight channel combined with satellite communications for beyond line of sight operations. The proposed design includes network-level security over the radio interfaces, automatic data link selection, support of remote video terminals, and access connectivity toward external IPv6 networks.This work has been partially granted by the Spanish Ministry of Defense through the DRONE project (DN8644-COINCIDENTE-10032110042).

Towards Effective Social Insurance in Latin America : The Importance of Countercyclical Fiscal Policy
