Cyclical mastalgia is a common complaint, with a potentially important relationship to breast cancer risk. In the last decade, case-control studies have reported that cyclical mastalgia could be considered as an independent risk factor for breast cancer. The subjectivity of a retrospectively collected symptom questioned the validity of this finding. We have examined the association between cycl...

I am induced to make some remarks upon this subject of obstinate vomiting in pregnancy, from the fact that within the last five years three cases of albuminuria during gestation have come under my observation, in all of which untoward results occurred, and in two of these obstinate vomiting was the prominent symptom. In one of the cases?the only one of which I mean to give complete details, the...

Ravi Bansal and Amir Yaron (2004) developed the Long Run Risk (LRR) model which emphasizes the role of long run risks, that is, low-frequency movements in consumption growth rates and volatility, in accounting for a wide range of asset pricing puzzles. In this article we present a generalized LRR model, which allows us to study the role of cyclical fluctuations and macroeconomic crises on asset...

MASSIMO FRANCHI AND PAOLO PARUOLO PRELIMINARY VERSION Abstract. This paper presents an additive decomposition of the moving average representation of VAR processes into cyclical components. We give a de nition of cyclical component that encompasses seasonal components as well as (stationary) long-run and short-run uctuations. Each cyclical component is univariate and is characterized by a spect...

I study the cyclical behavior of an equilibrium search model with endogenous job creation and destruction, with focus on the model’s failure to match the observed cyclical volatility of unemployment. Job creation in the model is influenced by wages in new matches. I summarize microeconometric evidence on wages in new matches and show that the key model elasticities are consistent with the evide...

Can discrete, single-shot movements and continuous, cyclical movements be reduced to a single concept? In the classical, computational approach to human motor behaviour, cyclical aimed movement has general19 been considered to derive from discrete primitives through a concatenation mechanism. Much importance, accordingly, has been attached to discrete-movement paradigms and to techniques allowi...
