A redução eletroquímica do Furoato de Diloxanida (FD) em acetonitrila sobre um eletrodo de carbono vítreo foi estudada neste trabalho. Foi observado que o FD é reduzido após uma transferência reversível de um elétron seguida por uma reação química irreversível, diagnosticada, como uma ruptura de uma ligação C-Cl. A redução do FD foi estudada por voltametria de varredura linear (LSV), pulso dife...

This paper analyzes optimal non-linear portfolio management contracts. We consider a setting where the investor faces moral hazard with respect to the effort and risk choices of the portfolio manager. The manager’s employment contract promises her: (a) a fixed payment, (b) a proportional asset-based fee, (c) a benchmark-linked fulcrum fee, and (d) a benchmark-linked option-type “bonus” incentiv...

The lack of an appropriate external data model is one of the reasons for the dearth of eeective network management applications. Many network management computations over Management Information Bases (mibs) cannot be practically accomplished through remote interactions. This paper describes the design of an mib Computations System that supports the dynamic deenition of external data models for ...

O increasingly seek solutions to their open-ended design problems by employing a contest approach in which search over a solution space is delegated to outside agents. We study this new class of problems, which are costly to specify, pose credibility issues for the focal firm, and require finely tuned awards for meeting the firm’s needs. Through an analytical model, we examine the relationship ...

The XACML standard defines an XML based language for defining access control policies and a related processing model. Recent work aims to add delegation to XACML in order to express the right to administrate XACML policies within XACML itself. The delegation profile draft explains how to validate the right to issue a policy, but there are no provisions for removing a policy. This paper proposes...

We analyze a principal-agent problem with moral hazard where a principal searches for an opportunity of uncertain return, and hires an agent to evaluate available options. The agent’s effort affects the informativeness of a signal about an option’s return. Based on the information provided by the agent, the principal decides whether to exercise the option at hand. We derive properties of the op...

We report on the synthesis of complexes hav ing two equiva lent redox active 2,5-dimethylazafe rrocenyl entities connected by heteroaryl (heteroaryl = thiophenyl, bithiophenyl and pyridyl) bridges. The new compounds have been investigated by various electrochemical techniques including cyclic voltammetry (CV), differential pulse voltammetry (DPV) and square wave voltammetry (SW) and were found ...
