The medical and economic importance of ticks has long been recognized due to their ability to transmit diseases to humans and animals. Ticks cause great economic losses to livestock, and adversely affect livestock hosts in several ways. Loss of blood is a direct effect of ticks acting as potential vector for haemo-protozoa and helminth parasites. Blood sucking by large numbers of ticks causes reduction in live weight and anemia among domestic animals, while their bites also reduce the quality of hides. However, major losses caused by ticks are due to their ability to transmit protozoan, rickettsial and viral diseases of livestock, which are of great economic importance world-wide. There are quite a few methods for controlling ticks, but every method has certain shortcomings. The present review is focused on ticks importance and their control. 相似文献

This article draws primarily upon Asian research, literature, and experience to describe the open and dualmode universities of East and South Asia. It describes their origins, admissions, development, delivery methods, and applications of technology. It discusses their successes and failures and the contributing political, social, economic, and cultural factors. It questions whether Asian distance education is best served by adopting Western models or whether there is need for the evolution of indigenous systems more firmly based upon local, vocational, social, and cultural needs. It considers faculty development and performance improvement issues and concludes by arguing for more research and evaluation to increase the institutions' standing with the governments, students, and communities they serve. 相似文献

- 170 early career researchers interviewed three times over 2 years, have uniquely contributed towards a stress test of scholarly communications and cracks have been identified.
- The perfect storm created by the convergence of millennial values and the pandemic appears to have fast-forwarded the cracking process, perhaps, for the good.
- The cracks in question are: (1) peer review; (2) reputational assessment; (3) unethical/questionable practices; (4) collaboration; (5) networking.
