Las representaciones gráficas en tareas académicas universitarias

Leer y escribir textos académicos es el eje principal del aprendizaje en la universidad; sin embargo, parece que el manejo, interpretación y construcción de otros tipos de sistemas de representaciones es fundamental en la enseñanza de Ciencias. En este trabajo se presenta un análisis de consignas que se ofrecen a estudiantes universitarios de Ciencias Biológicas, en donde se solicita el uso, lectura o producción de representaciones externas de tipo figurativas. El análisis se realizó en dos sentidos complementarios: primero, nos centramos en la caracterización de la naturaleza representacional de la información gráfica, para luego atender a los niveles de procesamiento de las mismas. Tras este análisis se presentan algunas consideraciones sobre la importancia y la riqueza cognitiva potencial del trabajo con representaciones en clases de Ciencias

Political Institutions and Street Protests in Latin America

This paper argues that where institutions are strong, actors are more likely to participate in the political process through institutionalized arenas, while where they are weak, protests and other unconventional means of participation become more appealing. This relationship is explored empirically by combining country-level measures of institutional strength with individual-level information on protest participation in 17 Latin American countries. Evidence is found that weaker political institutions are associated with a higher propensity to use alternative means for expressing preferences, that is, to protest. Also found are interesting interactions between country-level institutional strength and some individual-level determinants of participation in protests

Does Energy Consumption Respond to Price Shocks? Evidence from a Regression-Discontinuity Design

This paper exploits unique features of a recently introduced tariff schedule for natural gas in Buenos Aires to estimate the short-run impact of price shocks on residential energy utilization. The schedule induces a non-linear and nonmonotonic relationship between households accumulated consumption and unit prices, thus generating an exogenous source of variation in perceived prices, which is exploited in a regression-discontinuity design. The estimates reveal that a price increase in the utility bill received by consumers causes a substantial and prompt decline in gas consumption. Hence they suggest that policy interventions via the price mechanism, such as price caps and subsidies, are powerful instruments to influence residential energy utilization patterns, even within a short time span

Are We All Playing the Same Game? The Economic Effects of Constitutions Depend on the Degree of Institutionalization

The understanding of the economic effect of formal institutional rules has progressed substantially in recent decades. These formal analyses have tended to take for granted that institutional arenas such as Congress are the places where decision-making takes place. That is a good approximation in some cases (such as many developed countries today) but not in others. If countries differ in how institutionalized their policymaking is, it is possible that the impact of formal political rules on policy outcomes might depend on that. This paper explores that hypothesis and finds that some important claims regarding the impact of constitutions on policy outcomes do not hold for countries in which institutionalization is low. The findings suggest the need to develop a broader class of policymaking models in which the degree to which decision-making follows 'the rules' is also endogenized

Political Institutions, State Capabilities and Public Policy: International Evidence

This paper introduces preliminary evidence from a cross-country database of policy characteristics and potential uses of that database. While most databases have emphasized either the content of policies (e.g., size of government deficits) or countries' formal institutions (e.g., political regime, electoral system), the variables in this database reflect the policymaking capabilities of different polities. The paper attempts to explain these policy characteristics as depending on the workings of political institutions, using a logic emphasizing intertemporal political compromise. The paper also contrasts this logic with alternatives such as the veto players approach. The paper concludes by suggesting the use of these policy characteristics or state capabilities as explanatory variables for the effectiveness of public spending in various social areas

The Institutional Determinants of Political Transactions

Public policies are the outcome of the interaction among a variety of key political actors, each with its own preferences and incentives, who meet in different arenas and interact within the constraints of the institutions that frame their engagement. Therefore, to recognize the reasons behind the success or failure of any public policy it is necessary to understand the country's political institutions and the policymaking process they in turn help shape. This document looks at a number of those key actors, institutions, and arenas, with the aim of examining the roles, incentives, and capabilities of each of the actors in the policymaking process, by drawing from an extensive literature in political science and political economy. Each of the actors is looked at individually but connected to the other actors by linking the impact of political institutions on their incentives to the features of the policymaking game. Hopefully, this document will provide researchers with the tools necessary to embark in the fascinating analysis of policymaking processes not only for Latin American countries but also for other parts of the world

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.
