This study examines the opinions of print journalists regarding the use of dialogic components by Fortune 500 company web pages designed specifically for use by the press. Results showed that journalists recognize and appreciate the growing presence of dialogic components of corporate websites, but that a level of distrust and sense of manipulations still exists. This study also suggests the addition of a tenet to existing dialogic communications typologies, one of “relationship building and enhancement”.  相似文献

Statistics show that remittances inflow to Nigeria grew from US$3,000,000 in 1978 to over US$22 billion in 2017. Theoretically, such a large inflow of foreign currency into an economy may lead to Dutch diseases. This study, therefore, investigated whether the massive inflow of remittances into the economy causes Dutch disease. Given that the model had both I(0) and I(1) variables, ARDL/Bound testing methodology was used with annual data from 1981 to 2016. The ARDL result showed that migrant remittances have a significant positive effect on the real effective exchange rate in Nigeria in the long run. Specifically, a one per cent increase in the inflows of remittances increases the real effective exchange rate of Naira by 0.44 per cent in the long run. This appreciation of the Nigerian Naira relative to other competing nations encourages import and discourages export, leading to the Dutch disease effect.  相似文献

When making policy suggestions regarding tobacco use, it is important to consider why tobacco use has proved such a difficult behavior to eradicate. The articles in this issue have identified a number of variables that we would be well served to consider when creating tobacco policy. First, tobacco use has been difficult to eradicate because of the addictive nature of nicotine. Even though many smokers wish to quit, the addictive nature of the product makes this difficult. A second variable that compounds this problem is that tobacco addiction typically begins in adolescence. The decision-making process used by adolescents that may lead to tobacco use may be particularly difficult to alter, thus making smoking initiation a difficult process in which to intervene. Finally, it is important to consider the political power of the tobacco industry and to identify promising methods of overcoming this power when creating policy. These might include innovative legal strategies and searching for compromises that can reduce tobacco use while protecting important tobacco constituencies.  相似文献

Social Vulnerability to Environmental Hazards*   总被引:5,自引:0,他引:5  
Objective. County‐level socioeconomic and demographic data were used to construct an index of social vulnerability to environmental hazards, called the Social Vulnerability Index (SoVI) for the United States based on 1990 data. Methods. Using a factor analytic approach, 42 variables were reduced to 11 independent factors that accounted for about 76 percent of the variance. These factors were placed in an additive model to compute a summary score—the Social Vulnerability Index. Results. There are some distinct spatial patterns in the SoVI, with the most vulnerable counties clustered in metropolitan counties in the east, south Texas, and the Mississippi Delta region. Conclusion. Those factors that contribute to the overall score often are different for each county, underscoring the interactive nature of social vulnerability—some components increase vulnerability; others moderate the effects.  相似文献

Summary.  To analyse functional status transitions in the older population better, we fit a semi-Markov process model to data from the 1992–2002 Medicare Current Beneficiary Survey. We used an analogue of the stochastic EM algorithm to address the problem of left censoring of spells in longitudinal data. The iterative algorithm converged robustly under various initial values for the unobserved elapsed durations of spells in progress at base-line. Results on life expectancy and recovery from functional limitations based on the semi-Markov process model differ from those based on the traditional multistate life-table method. The proposed treatment of left-censored spells has the potential to expand the modelling capability that is available to researchers in fields where left censoring is a concern.  相似文献

Gambling is an ancient economic activity, but despite its universality and importance, no single explanation for the demand for gambles has gained ascendance among economists. This paper suggests that the demand for gambles is based on the ability to obtain “something for nothing.” That is, the gain from gambling is not merely additional income, but additional income for which the gambler does not need to work. Thus, to fully understand gambling behavior, it must be placed in a labor supply context. The theory is tested empirically using the Survey of Gambling in the U.S. Support for the theory is found.  相似文献

Despite an overall decrease in new farm operations, the number of women farm operators grew 30 percent between 2002 and 2007, with 300 percent growth since 1978. This research suggests, however, that opportunities for women have unfolded unevenly. We argue that women's opportunities to farm are affected by their social location and life course, suggesting that as their lives unfold across specific cultural and economic moments, different cohorts of women experience divergent opportunities to farm. Using in‐depth interviews with women engaged in sustainable farming in the Inland Northwest, this article examines how women access farmland. Our findings suggest three methods for access: (1) access through the traditional means of marrying a male farmer and then carving out space for one's self as a farmer; (2) access later in life after a life‐altering event like divorce and using personal financial means, such as retirement income or selling appreciated property; (3) access at a young age through the pooling of marital resources with a husband who works off the farm. Our research suggests that women's land access should not be presumed a progressive narrative and suggests the need for a more complex understanding of the challenges that women in agriculture face today despite their increased presence in farming.  相似文献
