Intimate partner violence and perinatal health: a systematic review
2019
Background Physical, psychological, and sexual intimate partner violence (IPV) has been described in the literature as different types of IPV experienced by women during pregnancy all over the world. Objectives To review and summarise systematically the empirical evidence on the links between IPV during pregnancy and the perinatal health of mothers and fetuses/neonates. Search strategy MEDLINE (Ovid), CINAHL, Embase, Nursing@ovid (Ovid), and LILACS were performed (2008-2018). Selection criteria Observational studies that examined perinatal health outcomes (i.e. pre-term birth, low birthweight, miscarriage, perinatal death, and premature rupture of membranes) in pregnant women exposed to IPV…
Le processus d'auto-sélection des filles à l'entrée en première
1993
International audience; Le niveau de la classe de seconde appara\ⁱt tout à fait déterminant dans la différenciation des carrières scolaires avec en particulier l'émergence de différences entre garçons et filles. Cette recherche se centre sur les mécanismes qui produisent ces différences, et notamment le moindre accès des filles à la première S. Il ressort, sur ce dernier point, que la situation des filles ne renvoie pas à des résultats plus faibles dans les matières scientifiques. Au contraire, les filles devraient plus fréquemment que les garçons accéder à la 1ere S si l'orientation dans cette classe ne dépendait que des notes et des progressions dans les différentes matières. En fait, le …
The effect of composite resin preheating on marginal adaptation of class II restorations
2020
Background One of the problems with a high filler content composite resins is gap formation at restorative material-tooth interface. The present study investigated the effect of preheating composite resins on the formation of marginal gap in Cl II restorations. Material and Methods In this in vitro study Sixty Cl II cavities were prepared on the mesial and distal surfaces of 30 extracted premolar teeth. The gingival floor of cavities was placed 1 m below the CEJ. The samples were randomly allocated to 4 groups for restoration placement: group 1, Filtek P60 composite resin at room temperature; group 2, Filtek P60 composite resin at 68°C; group 3, X-tra fil composite resin at room temperature…
Revamping Research on Unrelated Diversification Strategy: Perspectives, Opportunities and Challenges for Future Inquiry
2015
With the aim of achieving an advanced understanding of current research on unrelated diversification and providing fruitful groundwork to foster active interchange between disciplinary traditions, this paper detects articles from two relevant research streams; i.e., strategic management and financial economics. We first provide a brief overview of management thinking on unrelated diversification strategy. Then, we present a conceptual map that offers a comprehensive appreciation of unrelated diversification strategy antecedents (i.e., environmental and institutional, organizational value-enhancing, and managerial drivers), implementation process (i.e., managerial complexity, misallocation o…
Stock Return Volatility on Scandinavian Stock Markets and the Banking Industry: Evidence from the Years of Financial Liberalisation and Banking Crisis
1999
This paper investigates the evolution of the (conditional) volatility of returns on three Scandinavian markets (Finland, Norway and Sweden) over the turbulent period of the past decade, namely the overlapping periods of financial liberalisation, drastically changing macroeconomic conditions and banking crisis. We find that even over this relatively turbulent period volatility is in most cases successfully captured by past volatility and shocks to past volatility, ie by a (symmetric) GARCH process. In each country banking crisis has induced regime shifts in (unconditional) volatility. We also find evidence for cross-country volatility spillovers during the banking crisis episodes. The estima…
The Effects of Internationalization on CEO Compensation
2004
This study examines the relation between the internationalization of firms and CEO compensation. Starting from a sample of Norwegian and Swedish listed firms, we analyze the effects of internationalization as manifest in the capital market (international cross-listing), the market for corporate control (foreign board membership), and the product and service market (export and foreign sales). We conclude that all three markets contribute positively to the compensation level of CEOs. We argue that part of the higher CEO compensation in internationally oriented firms - as compared to less internationalized firms within the same country - reflects a risk premium for reduction in job security.Pu…
Robustness of the risk–return relationship in the U.S. stock market
2008
Abstract Using GARCH-in-Mean models, we study the robustness of the risk–return relationship in monthly U.S. stock market returns (1928:1–2004:12) with respect to the specification of the conditional mean equation. The issue is important because in this commonly used framework, unnecessarily including an intercept is known to distort conclusions. The existence of the relationship is relatively robust, but its strength depends on the prior belief concerning the intercept. The latter applies in particular to the first half of the sample, where also the coefficient of the relative risk aversion is smaller and the equity premium greater than in the latter half.
Illiquidity Risk and the Long-Run Underperformance of Seasoned Equity Issues in the Spanish Market
2008
This paper presents new evidence on potential risk-based explanations for the low SEO returns in the year after the issue. Specifically, we analyse whether the issue leads to a long-term higher stock liquidity that implies that SEO stocks have lower expected return due to lower exposure to liquidity risk factor. Therefore, we investigate if Spanish SEO firms experience significant changes in long-term liquidity after the issue. Results suggest that SEO-firm liquidity increases significantly in the year after the issue. Finally, we explore the post-performance of SEO firms explicitly accounting for liquidity risk. In particular, we employ the three factor model by Fama and French (1993) exte…
Exchange Rate and Inflation Risk Premia in the UME
2012
This paper tests the effects of exchange rate and inflation risk factors on asset pricing in the European Union (EU) stock markets. This investigation is motivated by the results of Vassalou (2000) [Journal of International Money and Finance, 19, 433-70] showing that both exchange rate and foreign inflation are generally priced in equity returns, and the opportunity to evaluate the causality between these sources of risk after the elimination of the EU currency risks because of the adoption of the single currency. Our results show that both exchange rate and inflation risks are significantly priced in the pre- and post-euro periods. Moreover, the size of exchange rate and inflation risk pre…
Dynamic Asset Allocation Strategies Based on Unexpected Volatility
2013
In this paper we document that at the aggregate stock market level the unexpected volatility is negatively related to expected future returns and positively related to future volatility. We demonstrate how the predictive ability of unexpected volatility can be utilized in dynamic asset allocation strategies that deliver a substantial improvement in risk-adjusted performance as compared to traditional buy-and-hold strategies. In addition, we demonstrate that active strategies based on unexpected volatility outperform the popular active strategy with volatility target mechanism and have the edge over the widely reputed market timing strategy with 10-month simple moving average rule.
