The Politics of Federalism in Argentina: Implications for Governance and Accountability

This paper contributes to an agenda that views the effects of policies and institutional reforms as dependent on the structure of political incentives for national and subnational political actors. The paper studies political incentive structures at the subnational level and the mechanisms whereby they affect national-level politics and policymaking at the national level in Argentina, a highly decentralized middle-income democracy, Argentina. The Argentine political system makes subnational political power structures very influential in national politics. Moreover, most Argentine provinces are local bastions of power dominated by entrenched elites, characterized by scarce political competition, weak division of powers, and clientelistic political linkages. Political dominance in the provinces and political importance at the national level reinforce each other, dragging the Argentine political and policymaking system towards the practices and features of its most politically backward regions

The potential of unmanned aerial systems for sea turtle research and conservation: A review and future directions

This is the final version. Available on open access from Inter Research via the DOI in this recordThe use of satellite systems and manned aircraft surveys for remote data collection has been shown to be transformative for sea turtle conservation and research by enabling the collection of data on turtles and their habitats over larger areas than can be achieved by surveys on foot or by boat. Unmanned aerial vehicles (UAVs) or drones are increasingly being adopted to gather data, at previously unprecedented spatial and temporal resolutions in diverse geographic locations. This easily accessible, low-cost tool is improving existing research methods and enabling novel approaches in marine turtle ecology and conservation. Here we review the diverse ways in which incorporating inexpensive UAVs may reduce costs and field time while improving safety and data quality and quantity over existing methods for studies on turtle nesting, at-sea distribution and behaviour surveys, as well as expanding into new avenues such as surveillance against illegal take. Furthermore, we highlight the impact that high-quality aerial imagery captured by UAVs can have for public outreach and engagement. This technology does not come without challenges. We discuss the potential constraints of these systems within the ethical and legal frameworks which researchers must operate and the difficulties that can result with regard to storage and analysis of large amounts of imagery. We then suggest areas where technological development could further expand the utility of UAVs as data-gathering tools; for example, functioning as downloading nodes for data collected by sensors placed on turtles. Development of methods for the use of UAVs in sea turtle research will serve as case studies for use with other marine and terrestrial taxa

Alien Invasive Slider Turtle in Unpredicted Habitat: A Matter of Niche Shift or of Predictors Studied?

BACKGROUND: Species Distribution Models (SDMs) aim on the characterization of a species' ecological niche and project it into geographic space. The result is a map of the species' potential distribution, which is, for instance, helpful to predict the capability of alien invasive species. With regard to alien invasive species, recently several authors observed a mismatch between potential distributions of native and invasive ranges derived from SDMs and, as an explanation, ecological niche shift during biological invasion has been suggested. We studied the physiologically well known Slider turtle from North America which today is widely distributed over the globe and address the issue of ecological niche shift versus choice of ecological predictors used for model building, i.e., by deriving SDMs using multiple sets of climatic predictor. PRINCIPAL FINDINGS: In one SDM, predictors were used aiming to mirror the physiological limits of the Slider turtle. It was compared to numerous other models based on various sets of ecological predictors or predictors aiming at comprehensiveness. The SDM focusing on the study species' physiological limits depicts the target species' worldwide potential distribution better than any of the other approaches. CONCLUSION: These results suggest that a natural history-driven understanding is crucial in developing statistical models of ecological niches (as SDMs) while "comprehensive" or "standard" sets of ecological predictors may be of limited use

The Presidency and the Executive Branch in Latin America: What We Know and What We Need to Know

The presidential politics literature depicts presidents either as all- powerful actors or figureheads and seeks to explain outcomes accordingly. Th e president and the executive branch are nonetheless usually treated as black boxes, particularly i n developing countries, even though the presidency has evolved into an extremely complex branch of government. While these developments have been studied in the U nited States, far less i s known in other countries, particularly in Latin America, where presi dential systems have been considered the source of all goods and evils. To help close the knowledge gap and explore differences in policymaking characteristics not only between Latin America and the US but also across Latin American countries, this paper s ummarizes the vast literature on the organization and resources of the Executive Branch in the Americas and sets a research agenda for the study of Latin American presidencies.Fil: Bonvecchi, Alejandro.

The Political Economy of Fiscal Reform in Latin America: The Case of Argentina

This paper investigates the political economy of fiscal reform activism in Argentina since the late 1980s. Between 1988 and 2008, tax legislation was changed 83 times, fiscal federal rules 14 times, and budgetary institutions sixteen times. Tax and budgetary reforms moved from centralizing revenue sources and spending authority in the federal government to mild decentralization lately. Fiscal federal rules combined centralization of revenues and management in the federal government with short-term compensations for the provinces. This paper contends that reform activism can be explained by the recurrence of economic and policy shocks while reform patterns may be accounted for as consequences of the decreasing political integration of national parties in a polity whose decisionmaking rules encourage the formation of oversized coalitions. The decrease in political integration weakened the national party leaderships ability to coordinate intergovernmental bargaining, and strengthened the local bosses and factions needed to form oversized coalitions
