Race and social organization: An economic perspective

Conclusion Improvements in the economic, political, and social status of Blacks are joint effects. Improvement in one is unlikely without concommitant improvements in the others; this is a multiedge sword.Success in any of the areas is correlated with improvement in the others—synergism. On the other hand, failure to realize the interdependencies makes success or improvement in any of the areas unlikely.     

Neglected Rural Public Health Issue： The Case of Intestinal Roundworms

Despite increasing institutional and financial support, certain public health issues are still neglected by the Chinese Government. The present paper examines the soil-transmitted helminth （STH） infection and reinfection rates by conducting a survey on 1724 children in Guizhou Province, China. Our results indicate that 37.5 percent of children had been infected with one or more of the three types of tested STH. However, only 50.4 percent of children reported having taken deworming medicine during the 18-month period before the survey. Of those who reported being dewormed, 34.6 percent tested positive for STH infections. Poverty and number of siblings are significantly and positively correlated with infection and reinfection, and parental education is significantly and negatively correlated with infection and reinfection. Given the ineffectiveness of treatment in these areas to date, for anthelminthic campaigns to actually succeed, China must pay more attention to local- level incentives to improve children＇s health.     

Critical Reflective Organizations: An Empirical Observation of Global Active Citizenship and Green Politics

Relationships between the environmental and economic dimensions of sustainability have been solidly specified, but relatively little attention has been given to the social sphere. The current study attempts to fill this gap by integrating corporate environmentalism more fully with concepts of corporate sustainability. This investigation draws specifically from neo-Habermasian critical environmental theory research and brings three concepts together for closer empirical examination: the public sphere, the communicative rationality, and discursive design with the goal of capturing whether critical and reflective organizational systems (CROS) among the selected sample of business participants are in fact developing. Using content analysis on corporate social responsibility (CSR) reports, the study reveals that some business organizations appear to be on the brink of developing a type of learning environment consistent with CROS thinking. The empirical findings also suggest that there is a transformative effect on citizenship that can result from the teaching and learning that is facilitated by voluntary CSR initiatives.     

Singular value decomposition in cointegration analysis: a note regarding the difference stationary series

Many methods and techniques have been developed gradually to compute cointegration vectors. We present here a comparatively simple method for computing the matrix of cointegrating vectors, by applying singular value decomposition. With this method, one can easily accommodate in the cointegrating vectors any deterministic factors, such as a dummy, apart from the constant term and the trend. Besides the errors corresponding to the finally selected cointegrating vector have the property of minimum variance. It is noted that this procedure is not mentioned in the relevant literature. Additionally, a sequential technique is introduced, for determining the order of integration for a given series. With this procedure one can directly detect whether the differencing process produces a stationary series or not, since it seems to be a common belief that differencing a variable (one or more times) we will always get a stationary series [Harris, R.: Using Cointegration Analysis in Econometric Modelling. Prentice Hall, London (1995)]. It will be seen that this is not necessarily the case.
