This article reports on work designed to measure the time required for a change in a stock's price to be fully reflected in the price of a warrant on that stock. The method employed to measure the adjustment speed is the bivariate transfer function technique of Box and Jenkins. An interesting aspect of the study is the use of trade-by-trade data for measuring stock and warrant returns. The evidence presented here suggests that warrant prices adjust quickly to changes in stock prices. In addition, evidence concerning the ability of the estimated models to forecast warrant prices is presented. 相似文献

Sarah Palin clearly holds a powerful appeal for a right‐wing constituency although even her most fervent followers may doubt that she is electable. This article examines the basis of her appeal. We argue that it can be summed up as an appeal to American authenticity, which consists of several elements: the valorization of small town ordinary life takes second place to faith and religious commitment; an equal faith in American exceptionality implies that Americans should never be apologetic about their country and never waver in their belief in its special greatness; the final elements are a foundational libertarian creed and a peculiar brand of right‐wing populism. However, for all her affinities with classical right‐wing sentiment, Sarah Palin, we argue, brings something new to the mix: a genuinely maverick right‐wing feminism. That is why in the end, we call the Palin phenomenon a paradoxical one. 相似文献

Adoption Issues: Preparation of Psychologists and an Evaluation of the Need for Continuing Education
This study is an investigation of the level of preparation psychologists have in dealing with adoption issues and an assessment of the need for further education in treating triad members. A questionnaire was mailed to 497 psychologists randomly selected from the National Register of Health Service Providers in Psychology who received doctoral degrees between the years of 1990 and 1996. Two hundred and ten psychologists, all of whom were currently treating clients, participated in the study. Psychologists completed a Likert rating of their sense of preparation to treat triad members. The largest group (51%) rated themselves as Somewhat prepared, with the second largest group (23%) rating themselves as Not very prepared. Ninety percent reported they needed more education in adoption, and 81% reported interest in taking a continuing education course in adoption. Of the 210 participants, only 67 reported taking courses that dealt with adoption as part of their formal education. Of those psychologists who reported taking courses that involved adoption, they averaged only 1.3 courses during their undergraduate education, and 1.5 courses during graduate education, while the remaining 143 psychologists received no education in this area. When one considers the proportion of triad members seen clinically, this study suggests psychologists need more education and background information about the effects of the adoption process. 相似文献

A firm's capital budgeting and strategic planning decisions have the potential to affect many groups of people called stakeholders. A stakeholder is any group or individual who can affect or is affected by the achievement of the firm's objectives. This study examines whether the presence of a code of ethics that specifically addresses capital budgeting/strategic planning decisions will significantly raise the awareness of social responsibility during the long-run planning process. This study also examines whether firm size is associated with the awareness of social responsibility during the long-run planning process. Support was found that a code of ethics that addresses long-range planning is associated with higher awareness during the planning process. Firm size was not found to be statistically different. 相似文献

Most research on residential mobility has documented a clear pattern: Residential and school moves are associated with poor academic performance. Explanations for this relationship, however, remain speculative. Some researchers argue that moving affects social relationships that are important to academic achievement. But the association between moving and school performance may be spurious; the negative correlation may be a function of other characteristics of people who move often. We offer several conceptual and analytical refinements to these ideas, allowing us to produce more precise tests than past researchers. Using longitudinal data, we find that differences in achievement between movers and nonmovers are partially a result of declines in social relationships experienced by students who move. Most of the negative effect of moving, however, is due to preexisting differences between the two groups. 相似文献

Household composition of older unmarried women in Hungary is analyzed using data from the 1984 microcensus. The principal determinants of household composition investigated are kin availability — the number of living children, siblings, and parents — health status, marital status, age, and income. A multinomial logit model distinguishing among five household types reveals that number of children, severe disabilities, age and income are all strongly related to household composition. Trends in fertility and mortality patterns suggest that kinship patterns will change in coming years; these results imply that household composition will, in turn, change as well. 相似文献

We examine nations which deviate significantly from the ?2/3 sizedensity slope previously observed for the aggregated political subdivisions of 98 modern nations and previously derived from the theory of timeminimization. We correct Stephan’s original list of deviant nations, demonstrate that all slopes more negative than ?2/3 were due to the erroneous inclusion of cities in the original data sets, develop a theory to account for the less negative deviant slopes, and test the theory both through statistical manipulation of current data and through analysis of available historical data. 相似文献
