The relationship between dividend policy and stock price volatility : a Canadian study
1 online resource (iv, 35 leaves)Includes abstract and appendices.Includes bibliographical references (leaves 28-29).The objective of this study is to explore the relationship between the stock price volatility and dividend policy (dividend yield and dividend payout ratio) for the Canadian stock market. According to the studies of Baskin (1989) and Allen and Rachim (1996), the multiple least squares regression model is applied in this paper. The sample of data is composed of 100 public firms which are listed on the Toronto Stock Exchange and paid dividends continuously from 2001 to 2011.
The results indicate that the dividend yield and the dividend payout ratio both have significantly negative relationship with the stock price volatility. In addition, earnings volatility is positively related to the stock price volatility and it is a statistically significant relationship. As a result, managers can partly control the stocks’ risks and thus affect investors’ investment decisions through a firm’s dividend policies
1-(2-HydrÂoxy-4,5-dimethÂoxyphenÂyl)propan-1-one
In the title compound, C11H14O4, isolated from the stems of Trigonostemon xyphophylloides, an intraÂmolecular O—H⋯O hydrogen bond helps to establish an essentially planar conformation for the molÂecule (r.m.s. deviation = 0.044 Å)
A new integral equation formulation for American put options
In this paper, a completely new integral equation for the price of an American put option as well as its optimal exercise price is successfully derived. Compared to existing integral equations for pricing American options, the new integral formulation has two distinguishable advantages: (i) it is in a form of one-dimensional integral, and (ii) it is in a form that is free from any discontinuity and singularities associated with the optimal exercise boundary at the expiry time. These rather unique features have led to a significant enhancement of the computational accuracy and efficiency as shown in the examples

Inhibition corrosion effect of extract from basella rubra on carbon steel in HCl solution
The inhibition behavior of fruit extract of Basella rubra on corrosion of carbon steel in 1 mol L-1 HCl solution was studied by weight loss and electrochemical methods. The adsorption of extract obeys Langmuir adsorption isotherm. Electrochemical results reveal that the inhibitor acts as mix type inhibitor but cathodically predominant. The separated substituents can also inhibit the corrosion of carbon steel in HCl solution efficiently. SEM and XPS results demonstrate that the protective layer formed by extract molecules can effectively inhibit corrosion process at metal surface. © 2020 The Authors
