Titcomb CP 《Journal of insurance medicine (New York, N.Y.)》2004,36(1):42-46
With increased hemodynamic stress, the heart must adjust to meet the greater demands placed upon it. This adjustment frequently involves an alteration or remodeling in its structure or geometry, which augments its performance and helps to maintain adequate function under changing conditions. One of the most important forms of remodeling that the heart may undergo is an increase in muscle mass in response to a pressure or volume overload or myocardial injury. This increase in muscle mass is known as left ventricular hypertrophy (LVH). LVH is of great importance from a risk selection perspective for two reasons: it is common, and it is associated with a significant increase in both morbidity and mortality risk. Thus, it is critical that both underwriters and medical directors be aware of this form of remodeling, its causes, diagnosis and consequences. 相似文献

Global apparel production and sweatshop labour: can raising retail prices finance living wages? 总被引:1,自引:0,他引:1
This paper provides some empirical evidence on issues raisedby the global anti-sweatshop movement. We first consider therelationship between wage and employment growth, finding noconsistent trade-off between them. We then measure the shareof labour costs in the production of garments in the US andMexico. We find that the retail price increases necessary toabsorb the costs of raising wages substantially are small, wellwithin the range of price increases that polls suggest US consumersare willing to pay. We close by considering some implicationsof these results. 相似文献

Recent papers involving binary choices have argued that increasingheterogeneity decreases positive feedback. We show that no suchresult holds in models where all agents make interior choices.The results in the binary choice case arise for two reasons.First, if we increase heterogeneity without limit but imposea bounded choice set, then almost all players eventually becomecompletely unresponsive, preferring some corner so stronglythat they do not react to any feasible change in the behaviorof others. Second, discrete choice permits the constructionof strong, but fragile, positive feedbacks through compositioneffects. 相似文献
