Human Dimensions of the Ecosystem Approach to Fisheries: An Overview of Context, Concepts, Tools and Methods
This document aims to provide a better understanding of the role of the economic, institutional and sociocultural components within the ecosystem approach to fisheries (EAF) process and to examine some potential methods and approaches that may facilitate the adoption of EAF management. It explores both the human context for the ecosystem approach to fisheries and the human dimensions involved in implementing the EAF. For the former, the report provides background material essential to understand prior to embarking on EAF initiatives, including an understanding of key concepts and issues, of the valuation of aquatic ecosystems socially, culturally and economically, and of the many policy, legal, institutional, social and economic considerations relevant to the EAF. With respect to facilitating EAF implementation, the report deals with a series of specific aspects: (1) determining the boundaries, scale and scope of the EAF; (2) assessing the various benefits and costs involved, seen from social, economic, ecological and management perspectives; (3) utilizing appropriate decision-making tools in EAF; (4) creating and/or adopting internal incentives and institutional arrangements to promote, facilitate and fund the adoption of EAF management; and (5) finding suitable external (non-fisheries) approaches for financing EAF implementation
Quantum Computer Emulator
We describe a quantum computer emulator for a generic, general purpose
quantum computer. This emulator consists of a simulator of the physical
realization of the quantum computer and a graphical user interface to program
and control the simulator. We illustrate the use of the quantum computer
emulator through various implementations of the Deutsch-Jozsa and Grover's
database search algorithm.Comment: 28 pages, 4, figures, see also

Individual and couple decision behavior under risk: Evidence on the dynamics of power balance
This paper reports results of an experiment designed to analyze the link between risky decisions made by couples and risky decisions made separately by each spouse. We estimate both the spouses and the couples' degrees of risk aversion, we assess how the risk preferences of the two spouses aggregate when they make risky decisions and we shed light on the dynamics of the decision process that takes place when couples make risky decisions. We find that, far from being fixed, the balance of power within the household is malleable. In most couples, men have, initially, more decision-making power than women but women who ultimately implement the joint decisions gain more and more power over the course of decision making.Balance of power; Experiments; Household decision-making; Risk.
On a Linear Chaotic Quantum Harmonic Oscillator
We show that a linear quantum harmonic oscillator is chaotic in the sense of
Li-Yorke. We also prove that the weighted backward shift map, used as an
infinite dimensional linear chaos model, in a separable Hilbert space is
chaotic in the sense of Li-Yorke, in addition to being chaotic in the sense of
Devaney.Comment: LaTex file. Applied Mathematics Letters, to appea
Individual and Couple Decision Behavior under Risk:The Power of Ultimate Control
This paper reports results of an experiment designed to analyze the link between risky decisions made by couples, and risky decisions made separately by each spouse. We estimate both the individuals and the couplesâ degrees of risk aversion, and we analyze how the risk preferences of the two spouses aggregate when they have to perform joint decisions under risk. We show that the man has more decision power than the woman, but the womanâs decision power increases when she has ultimate control over the joint decision.
