La discrétion administrative et la mise en oeuvre d'une politique

This article deals with the relationships between the exercise of administrative discretion and the implementation of a policy. Chapter I defines administrative discretion as a power to make a choice in a particular case. This choice may be technical or political but in both instances relates to the implementation of a policy. The exercise of discretion is also situated within a system under the Rule of Law using H.L.A. Hart's concepts of primary and secondary rules. Chapter II deals with the exercise of discretion in relation to policy. First, if refers to K.C. Davis' model of confining, structuring and checking discretion. To confine discretion is to set the limits within which it should be exercised. To structure it is define the manner by which it is to be exercised notably in opening the decision-making process. To check discretion is to subject the decision to another authority. The next three sections of this chapter are concerned with legislative, regulatory and administrative policy. The first section studies legislative expressions of policy and their impact on the exercise of discretion. Secondly, the question of the choice between regulation and administrative discretion is analysed as is the control over that choice and the nature of regulation over it is decided to adopt it. Finally, the impact of an administrative discretion is seen when attacked by the citizen on the grounds that it fetters discretion, constitutes bias or when relied upon by the citizen. It is seen that in most cases, the administrator may structure his discretionary power in a manner respected by the courts

Vapor Synthesis and Thermal Evolution of Supportless, Metal Nanotubes and Application as Electrocatalysts

One of the major limitations of proton exchange membrane fuel cells (PEMFCs) is the high cost and poor durability of the currently preferred catalyst design, small Pt nanoparticles supported on high surface area carbon (Pt/C). Unsupported, high-aspect ratio nanostructured catalysts, or extended surface catalysts, are a promising paradigm as electrocatalysts for a number of electrochemical reactions. These extended surface catalysts generally exhibit higher specific activities compared to their carbon-supported nanoparticle counterparts that have been ascribed to their unique electronic, surface and structural properties. Extended surface catalysts frequently maintain enhanced durability over supported catalysts during fuel cell operation because they are not susceptible to the same modes of degradation inherent to small supported nanoparticles. Considering the success of extended surfaces as catalysts, we have synthesized metallic, mixed-phase, and alloyed bimetallic nanotubes by a chemical vapor deposition (CVD) technique to catalyze a number of reactions relevant for fuel cells. In this CVD process, metalorganic precursors, namely metal-acetylacetonates, are decomposed by a mild thermal treatment and deposited as conformal nanoparticulate layers within a sacrificial anodic alumina template. Following vapor deposition, the nanotube samples may be annealed while still in the template to induce a series of changes with implications on electrocatalysis, including nano-porosity, alloying, and surface coordination. This synthesis technique and successive thermal modification is applicable for the deposition of a number of metals. The metallic nanotubes prepared by this method are highly active catalysts for a host of electrochemical reactions that are promising for fuel cell applications. The effects of composition, heat treatment temperature and gas environment on the activity and durability of these materials have been studied for oxygen reduction, methanol oxidation, formic acid oxidation, and hydrogen oxidation

A Rolling Stone bows out [edition]

William C. Atkinson (1902–1992), Stevenson Professor of Hispanic Studies at Glasgow University for forty years, records his experiences during his final lecture tour in Latin America in 1971, when, among other countries, he visited Peru, Chile, Argentina, Venezuela and Brazil. Atkinson makes illuminating comparisons between social and political conditions in these countries in 1971 and how he had found them to be on his earlier visits to Latin America, usually sponsored by the British Council, in 1947, 1960 etc. Besides editing his account, Ann L. Mackenzie provides notes to elucidate Atkinson’s references to places, people and events

Paper Session II-A - Predictive Health & Reliability Management (PHARM)

PHARM was developed to address operational costs associated with Space Shuttle component failures, repair, and/or replacement processes by identifying components trending toward failure. Thus PHARM mitigates impacts to operational testing and mission performances by providing realistic need dates and historical performance data for component repair/replacement decisions and logistic provisioning. BRSS developed under an IR&D and NASA contract an OMS Vehicle Health Management testbed using qualification hardware in flight configuration. The testbed performs a complete and total automated checkout of an OMS Helium pressurization system. In the course of the automated checkout, key component performance data is saved, correlated and used to develop, prove, and demonstrate PHARM technologies. Via data acquisition, PHARM provides trending and forecasting capabilities for mission scheduling

A topology on the fundamental group.

For an arbitrary topological space algebraic topology prescribes a construction for a fundamental group. There is a natural way of imposing a topology on this set. We will examine this construction and the topological space which results. We use the following notation and definitions: 1. I f X and Y are topological spaces and ACX, BCY and if f:X+Y is a map, we write f: (X,A)➔(Y,B) if f(A)cB. 2. (Y,B)CX,A)={f: (X,A)+(Y,B)I f is continuous}. 3. 1=[0,1], the closed unit interval; i={O,l}, the points O and 1. 4. If X is a topological space and a£X, then R is an equivalence relation on (X,a) ( I ,I ) defined as follows: If f,gE(X,a)(I, i ) then fRg if and only if f and_ g are homotopic relative to I, written f��g rel I. That is, there exists a continuous function F: I xl+X such that F(O,t)= f(t), F(l,t)=g(t), F(x,O)=a, F(x,l)=a for all x,tsl. R is easily shown to be an equivalence relation, [2, p. 6]. We write Rf��{g£(X,a)(I,I )I gRf}. 5. When we speak of a topology on (Y,B) (X,A) we use the compact-open topology. The compact-open topology has subbasic sets of the form (C,U) where CCX i�� compact, UC f is open, and (C,U)��{fE(Y,_B)(X, A) I f(C)cU} . 6. Q(X,a)=(X,a) (I ,I ) with the compact-open topology is called the loop space of X at a
