In a context of low literacy rates and a high level of rurality, the use of rural radio in agricultural extension is a method that can bridge the gap that exists between researchers, extension workers, and farmers. This article examines the level of farmers’ access to rural radio in relation to gender and livelihoods. The study was conducted in Benin with 18 rural radio stations and 240 rice processors, using the sustainable livelihoods framework to examine the relationship between access to rural radio and livelihoods. Although the study cannot draw conclusions on causal relationships, rice processors who often listened to agricultural broadcasts had better social, financial, and human capital stocks compared to those who did not. Despite the efforts of 72% of the radio stations to link up with extension services, half of the rice processors rarely or never listened to agricultural broadcasts, because the timing of the broadcasts was inappropriate. Interactive radio sessions with farmers that involve government officials will need to address this if they are to become more effective. 相似文献

We have studied the degradation of sebaceous fingerprints on brass surfaces using silver electroless deposition (SED) as a visualization technique. We have stored fingerprints on brass squares either (i) in a locked dark cupboard or (ii) in glass‐filtered natural daylight for periods of 3 h, 24 h, 1 week, 3 weeks, and 6 weeks. We find that fingerprints on brass surfaces degrade much more rapidly when kept in the light than they do under dark conditions with a much higher proportion of high‐quality prints found after 3 or 6 weeks of aging when stored in the dark. This process is more marked than for similar fingerprints on black PVC surfaces. Identifiable prints can be achieved on brass surfaces using both SED and cyanoacrylate fuming (CFM). SED is quick and straightforward to perform. CFM is more time‐consuming but is versatile and can be applied to a wider range of metal surfaces than SED, for example brass surfaces which have been coated by a lacquer. 相似文献

This study examines the impact of the anti-inflation stabilization policies on the behavior of inflation in Croatia in the early 1990s and through the subsequent post-stabilization period using fractional integration techniques. Indeed, the implementation of the stabilization program in October 1993 brought immediate deflation with a relative high degree of inflation stability in the post-stabilization period. With allowance for a structural break corresponding to the stabilization program in October 1993, the degree of persistence was substantially reduced with the fractional differencing parameter being positive but close to zero in the post-stabilization period. 相似文献

The City of Pittsburgh and Allegheny County have electrical rates which are approximately 20-23 percent above the national average and are among the highest in the U.S. The following report examines the potential impact on the Pittsburgh Region of an industrial electrical rate reduction of 15 percent in Allegheny County. Simulations show that the reduction will slow the rate of decline in manufacturing employment and cause modest increases in employment growth in other sectors of the local economy. However, the rate reduction will have almost no impact on real disposable income per capita in the Region and will also have no recession dampening effect on the Region when the nation experiences a 10 percent, two-year decline in the demand for all durable goods. All simulations are run using the 1994 Pittsburgh REMI Model. 相似文献

How does age influence public opinion regarding controversial social issues? The issues at stake are: attitudes toward Muslims, Jews, Affirmative Action, immigration, abortion, and gays and lesbians. While we understand the importance of including opinions toward African-Americans among these categories, we found little data on opinions toward this group by age. We also discuss opinions toward Darwin’s theory of evolution and stem cell research since they were issues that pitted science against religion in American society and were important topics of intense political discussion. The selection of issues is based on the importance of these issues in public debate and electoral politics. A number of these issues, mainly those related to opinions toward religious and racial groups, reflect the development of American society and draw lines of possible disagreements and social cleavages. 相似文献

Reports of cybercrime have escalated over the past decade. While these crimes have increased, our understanding about the dynamics surrounding cyber offenders has not kept pace. Few studies have considered the characteristics of serious cyber criminals in comparison to other types of criminals. To fill this void in the literature, we examine a sample of cybercriminals appearing on the FBIs Most Wanted List and compare the characteristics of these offenders to other most wanted offenders. Results suggest that the most wanted cyber offenders are similar to other offenders in that it is a male-dominated offense category, but they are different from other offenders in that they are younger and more likely to exhibit certain types of physical and lifestyle characteristics. Implications for policy and future research are provided. 相似文献
