Devidend announcements and contagion effects: an investigation on the firm listed with Dhaka Stock Exchange

Changes in dividend convey information about the earnings of the announcing firm which in turn affect the price. Security price depends on current earnings, past earnings, and future prospect of earnings. Dividend relevant theory postulates that dividend policy, dividend initiation and changes in dividend carry information about the market value of the announcing firms. Accordingly, an unexpected increase in dividends conveys positive information about the future profitability of the firm and vice versa. Firm’s management is better informed than the market about the future prospects of their firm and therefore, their action relating to any financing decision conveys information to the investors. The principal purpose of this study was to examine the intra-industry information effects of announcements of dividend initiations of the firms associated with Dhaka Stock Exchange (DSE). To test this hypothesis, we used Herfindahl Index and Tobin’s q ratio. The study found that the intra-industry effects of dividend revisions are apparent

An investigation of heuristic decomposition to tackle workforce scheduling and routing with time-dependent activities constraints

This paper presents an investigation into the application of heuristic decomposition and mixed-integer programming to tackle workforce scheduling and routing problems (WSRP) that involve timedependent activities constraints. These constraints refer to time-wise dependencies between activities. The decomposition method investigated here is called repeated decomposition with con ict repair (RDCR) and it consists of repeatedly applying a phase of problem decomposition and sub-problem solving, followed by a phase dedicated to con ict repair. In order to deal with the time-dependent activities constraints, the problem decomposition puts all activities associated to the same location and their dependent activities in the same sub-problem. This is to guarantee the satisfaction of time-dependent activities constraints as each sub-problem is solved exactly with an exact solver. Once the assignments are made, the time windows of dependent activities are fixed even if those activities are subject to the repair phase. The paper presents an experimental study to assess the performance of the decomposition method when compared to a tailored greedy heuristic. Results show that the proposed RDCR is an effective approach to harness the power of mixed integer programming solvers to tackle the diffcult and highly constrained WSRP in practical computational time. Also, an analysis is conducted in order to understand how the performance of the different solution methods (the decomposition, the tailored heuristic and the MIP solver) is accected by the size of the problem instances and other features of the problem. The paper concludes by making some recommendations on the type of method that could be more suitable for different problem sizes

mixed donor macrocyclic moieties

The new phthalocyanine peripherally substituted with a twelve-membered dioxadiaza macrocycle was synthesized by cyclotetramerization of 1,2-bis(2-{4'-[(4'-methylphenyl)sulphonyl]- 1',7'-dioxa-4',10'-diazacyclododecane})-4,5-dicyanobenzene (4) which was obtained from 1,2-bis(2-{4'-[(4'-methylphenyl) sulphonyl]-1',7'-dioxa-4',10'-diazacyclododecane})- 4,5-dibromobenzene ( 3). Metallophthalocyanine was also prepared by the reaction of the dicyano-substituted macrocycle in the presence of anhydrous CuCN. The new compounds were characterized by a combination of elemental analysis, H-1 and C-13 NMR, IR, electronic and mass spectroscopies

A modern approach to estimate the bearing capacity of layered soil

This study is concerned with the bearing capacity of circular footings on a granular fill layer above a soft clay soil. The results of an extensive series of laboratory and field tests were used to define an empirical equation. This is generally done by estimating the dependent variable (e.g. bearing capacity) based on the independent variables (e.g. granular fill layer thickness, soil and footing parameters and settlement ratio). A logarithmic model has been developed by using regression analysis to estimate the bearing capacity of a circular footing resting on granular fill at any settlement ratio, using all possible regression techniques based on 342 field test data, to select the significant subset of the predictors. The results indicate that the logarithmic model serves a simple and reliable tool to predict the bearing capacity of circular footings placed on a granular fill with different thicknesses above a soft clay soil. And also, the validity of the developed formulation was verified with different plate load test results from literature. © 2017, Budapest University of Technology and Economics.
