What long-run returns can investors expect from the stock market?

This article analyzes how macroeconomic fundamentals and high price-earnings ratios on stocks will affect long-run returns. The first section reviews the stock market's recent performance and describes how investors and analysts have reacted to this performance. The second section shows how macroeconomic trends imply that long-run returns will remain close to their 10 percent historical average. The third section analyzes the long-run relationship between price-earnings ratios and returns. The section shows that high price-earnings ratios are consistent with lower long-run returns, and argues returns may have declined because the stock market is perceived as less risky.Stock market ; Stocks ; Stock - Prices

Personality Theory as a Predictor for Agile Preference

Since their arrival on the software development scene, agile software development methods have been a source of intense study. One promising aspect of research in relation to agile methods is personality theory. Although there have been some studies utilizing personality theory, to date no research has been performed to investigate the potential link between personality attributes and preference for agile methods. This study seeks to explore this research gap using a quantitative survey based approach. The outcome of this study provides evidence that there may not be a correlation between personality and agile methods, at least in terms of personality characteristics as measured by the Five Factor Model. In addition to this finding, the research provides a contribution in the form of an instrument to measure agile software development methodology preference

A Role for PPARβ/δ in Ocular Angiogenesis

The uses of highly selective PPARβ/δ ligands and PPARβ/δ knockout mice have shown a direct ability of PPARβ/δ to regulate angiogenesis in vitro and in vivo in animal models. PPARβ/δ ligands induce the proangiogenic growth factor VEGF in many cells and tissues, though its actions in the eye are not known. However, virtually, all tissue components of the eye express PPARβ/δ. Both angiogenesis and in particular VEGF are not only critical for the development of the retina, but they are also a central component in many common pathologies of the eye, including diabetic retinopathy and age-related macular degeneration, the most common causes of blindness in the Western world. This review, therefore, will discuss the recent evidence of PPARβ/δ-mediated angiogenesis and VEGF release in the context of ocular disorders

Effects of harvesting methods on sustainability of a bay scallop fishery: dredging uproots seagrass and displaces recruits

Fishing is widely recognized to have profound effects on estuarine and marine ecosystems (Hammer and Jansson, 1993; Dayton et al., 1995). Intense commercial and recreational harvest of valuable species can result in population collapses of target and nontarget species (Botsford et al., 1997; Pauly et al., 1998; Collie et al. 2000; Jackson et al., 2001). Fishing gear, such as trawls and dredges, that are dragged over the seafloor inflict damage to the benthic habitat (Dayton et al., 1995; Engel and Kvitek, 1995; Jennings and Kaiser, 1998; Watling and Norse, 1998). As the growing human population, over-capitalization, and increasing government subsidies of fishing place increasing pressures on marine resources (Myers, 1997), a clear understanding of the mechanisms by which fishing affects coastal systems is required to craft sustainable fisheries management

A CCIR aeronautical mobile satellite report

Propagation effects in the aeronautical mobile-satellite service differ from those in the fixed-satellite service and other mobile-satellite services because: small antennas are used on aircraft, and the aircraft body may affect the performance of the antenna; high aircraft speeds cause large Doppler spreads; aircraft terminals must accommodate a large dynamic range in transmission and reception; and due to their high speeds, banking maneuvers, and three-dimensional operation, aircraft routinely require exceptionally high integrity of communications, making even short-term propagation effects very important. Data and models specifically required to characterize the path impairments are discussed, which include: tropospheric effects, including gaseous attenuation, cloud and rain attenuation, fog attenuation, refraction and scintillation; surface reflection (multipath) effects; ionospheric effects such as scintillation; and environmental effects (aircraft motion, sea state, land surface type). Aeronautical mobile-satellite systems may operate on a worldwide basis, including propagation paths at low elevation angles. Several measurements of multipath parameters over land and sea were conducted. In some cases, laboratory simulations are used to compare measured data and verify model parameters. The received signals is considered in terms of its possible components: a direct wave subject to atmospheric effects, and a reflected wave, which generally contains mostly a diffuse component
