How Does the Government (Want to) Fund Science? Politics, Lobbying and Academic Earmarks

This paper examines academic earmarks and their role in the funding of university research. It provides a summary and review of the evidence on the supply of earmarks by legislators. It then discusses the role of university lobbying for earmarks on the demand side. Finally, the paper examines the impact of earmarks on research quantity and quality.

Academic Earmarks and the Returns to Lobbying

Despite a large literature on lobbying and information transmission by interest groups, no prior study has measured returns to lobbying. In this paper, we statistically estimate the returns to lobbying by universities for educational earmarks (which now represent 10 percent of federal funding of university research). The returns to lobbying approximate zero for universities not represented by a member of the Senate Appropriations Committee (SAC) or House Appropriations Committee (HAC). However, the average lobbying university with representation on the SAC receives an average return to one dollar of lobbying of $11-$17; lobbying universities with representation on the HAC obtain $20-$36 for each dollar spent. Moreover, we cannot reject the hypothesis that lobbying universities with SAC or HAC representation set the marginal benefit of lobbying equal to its marginal cost, although the large majority of universities with representation on the HAC and SAC do not lobby, and thus do not take advantage of their representation in Congress. On average, 45 percent of universities are predicted to choose the optimal level of lobbying. In addition to addressing questions about the federal funding of university research, we also discuss the impact of our results for the structure of government.

Complexity of colouring problems restricted to unichord-free and \{square,unichord\}-free graphs

A \emph{unichord} in a graph is an edge that is the unique chord of a cycle. A \emph{square} is an induced cycle on four vertices. A graph is \emph{unichord-free} if none of its edges is a unichord. We give a slight restatement of a known structure theorem for unichord-free graphs and use it to show that, with the only exception of the complete graph $K_4$, every square-free, unichord-free graph of maximum degree~3 can be total-coloured with four colours. Our proof can be turned into a polynomial time algorithm that actually outputs the colouring. This settles the class of square-free, unichord-free graphs as a class for which edge-colouring is NP-complete but total-colouring is polynomial

Demandas tecnológicas para o manejo florestal da castanha-do-brasil (Bertholletia excelsa Humb e Bompl).

A coleta e exportação de castanha-do-brasil occorem há várias décadas. NO entanto, iniciativas de estudos técnico-científicos relacionados a processamento e, principalmente, ao manejo das áreas de coleta são recentes, daí a grande lacuna de conhecimentos. É necessário estabelecer novas linhas de pesquisa nessas áreas, por meio de critérios que priorizem demandas, evitando desperdício de recursos financeiros e humanos, com maior eficácia no uso de recursos públicos e privados e atendendo aos anseios do setor produtivo, do consumidor e da sociedade como um todo.bitstream/CPAF-AC/3716/1/doc61.pd
