Offspring of parents with bipolar disorder (BD) are at high risk for psychiatric disorders, but mechanisms conferring risk are not well understood. Identifying and understanding factors that increase offspring vulnerability may inform intervention efforts. Three studies examined the following risk factors: (1) obstetric complications (OCs); (2) family functioning; and (3) clinical characteristi...

This paper investigates how the characteristics of information security incidents and disclosures in financial reports affect the valuation of a firm. Building on theories of disclosures in the accounting literature, we investigate investor reaction to disclosures through both quantitative and qualitative analyses. A cross-sectional analysis is first performed to examine the effect of the numbe...

This paper examines whether the overall market risk along with risks re‡ecting uncertainty related to the long run dynamics of market cash ‡ows (dividends) and discount rates (returns) price average returns on single-sorted portfolios of the Greek stock market. Following Campbell and Vuolteenaho (American Economic Review, 2004) we check whether these two types of risk provide an empirical impro...

Actinic keratoses (AKs) are common cutaneous lesions that develop as a result of ultraviolet (UV) radiation damage.1 Risk factors associated with AKs include advanced age, male gender, high degree of sun and/or artificial UV exposure, and fair skin.2 Epidemiological studies within Europe are limited and have provided highly variable estimates of AK point prevalence (1--38%).2--6 Cumulative sun ...

a r t i c l e i n f o This paper reexamines the liquidity effect on stock expected returns in the NYSE over the period 1926–2008, the pre-1963 period, for which there is a lack of research, and the post-1963 period. The results from the entire sample of 1926–2008 show that expected returns increase with the stock level illiquidity. However, illiquidity level has explanatory power in the cross-s...

This paper examines whether the overall market risk, along with risks re ecting uncertainty related to the long run dynamics of market cash ows (dividends) and discount rates (returns), price average returns on single-sorted portfolios in the Greek stock market. Our results suggest that a two-beta intertemporal capital asset pricing model explains half of the cross-sectional variation in averag...

The prevention of underage drinking and related outcomes focuses on strengthening protective factors. Using data from the National Longitudinal Study of Adolescent Health (N = 3,862), the authors examine the effects of protective factors from three domains of adolescents’ lives (individual, familial, and extrafamilial) on experiencing negative consequences of alcohol use, while controlling for ...

This paper explores some issues of model risk in asset pricing, in particular timeinconsistency. Since Ho and Lee (1986), a new class of no-arbitrage models have become increasingly popular both in the asset pricing literature and in the Þnancial industry. These models are said to allow for a perfect Þt of the term structure of the interest rates. In these models the current yield curve is an i...

Background/Aims: What are the implications of drinking with parents (DWP) on adolescents’ drinking behavior? We expanded the meagre body of research on this controversial issue by assessing the association between the frequency of DWP and adolescent high-risk drinking, taking a number of parental factors into account. Method: Data stemmed from a subsample of 14–17-year-old current drinkers (n =...
