BACKGROUND Cognitive reserve has been implicated as a possible protective factor in multiple sclerosis (MS) but to date no study has compared reserve-building activities across disease course or to healthy controls. This study aims to describe differences in reserve-building activities across the MS disease course and healthy controls. METHODS Secondary analysis of a cross-sectional cohort st...

Cerebral reserve capacity (or functional reserve) refers to the brain's ability to maintain function when confronted by degenerative processes. Functional reserve can be estimated by several associated measures, including premorbid brain size, premorbid IQ, and level of education attained. There is accumulating evidence that the magnitude of reserve capacity is important in determining the onse...

INTRODUCTION A lack of identifiers in health administrative databases limits our understanding of the cancer burden in First Nations. This study compares cancer risk factors and screening between First Nations in Ontario (on and off reserve) and non-Aboriginal Ontarians using two unique health surveys. METHODS We measured age-standardized prevalence estimates using the First Nations Regional ...

1. Marine protected areas are increasingly being recommended as an essential component of the management of exploited marine species, but virtually no attention has been given to the influence of parasites. This may be substantial, as a primary effect of marine reserves is to increase the density of an exploited population within the reserve relative to outside the reserve, which may facilitate...

I show that the benefit of a high reserve price in a commonvalues ascending auction is lower than in the observationally-equivalent private values setting. Put another way, when bidders actually have common values, empirical estimation based on a private values model will overstate the value of a high reserve price. Via numerical examples, I show that this same ranking typically applies to the ...

The value of no-take marine reserves as fisheries-management tools is controversial, particularly in high-poverty areas where human populations depend heavily on fish as a source of protein. Spillover, the net export of adult fish, is one mechanism by which no-take marine reserves may have a positive influence on adjacent fisheries. Spillover can contribute to poverty alleviation, although its ...

Utilities use operating reserve for frequency regulation. To ensure that the operating frequency and system security are well maintained, the operating grid codes always specify that the reserve quantity and response rate should meet some prescribed levels. This paper proposes a methodology to evaluate system’s contingency reserve for an isolated power network. With the presented algorithm to e...

We model the effect of a no-take reserve in a marine fishery management area, such as on a coral reef. Implicitly, eggs and larvae are mobile but adults are not; and there is open access fishing outside the reserve. A reserve is found to increase equilibrium catch if the prior ratio of stock to carrying capacity is less than a half, and the catch-maximising reserve proportion rises towards a ha...

Reserve requirements have traditionally been viewed as a key instrument of monetary policy. Indeed, textbook discussions of monetary policy typically center on the role of reserve requirements in determining the size of the money multiplier and the magnitude of bank credit expansion. In recent years, however, there has been a significant decline in the use of reserve requirements in the United ...
