Abstract Average ewe prolificacy is low across the U.S., while fixed and variable costs of production can be substantial, especially in traditional shed-lambing systems. Pasture-lambing can reduce input costs but can present greater risk of inclement weather, predation, and internal parasitism. The Composite IV is a ½ Romanov, ¼ Katahdin, and ¼ White Dorper hair sheep developed at the U.S. Meat Animal Research Center. Objectives were to summarize Composite IV ewe and lamb performance under a pasture-lambing system with minimal disruption through weaning. Lamb survival to and body weight at weaning were greatest for singles (0.90 and 19.9 kg, respectively), intermediate for twins (0.82 and 15.9 kg), and lowest for triplets (0.65 and 14.6 kg; P < 0.01). Number of lambs born and weaned per ewe lambing were lower at 1-yr of age (1.55 and 1.24, respectively) than at 3- to 5-yr of age (2.20 to 2.23 and 1.75 to 1.82; P < 0.01). Within mature ewes (2- to 5-yr-old), twin litters were most frequent (58.7%), triplets intermediate (24.7%), and singles least (16.6%). While number of lambs weaned and total litter weaning weight were greater for triplet- than twin-bearing ewes (2.06 vs 1.70 and 28.9 vs 26.0 kg, respectively; P < 0.01), triplet-bearing ewes lost 1.78 lambs per additional lamb weaned. Results suggest productivity in pasture-lambing systems can be enhanced by identifying complementary breed combinations, maintaining heterosis, and selecting for characteristics associated with reduced labor and enhanced well-being.

Subject. The article continues the discussion about the method of training aircraft engineers to work in the military and civil segments of aviation and rocket-and-space industry. Objectives. The purpose is to improve the training of Russian engineers to work in the competitive market environment, on the basis of the analysis of experience in training the aviation engineers in leading foreign technical universities. Methods. The study rests on the comparative analysis of implementation of major projects in the military and civil segments of aviation in the U.S. and Russia, as well as programs for training aircraft engineers in both countries. Results. The analysis shows that the duration of modern large military aviation projects in both countries is the same (the comparison of cost is impossible, due to information protection in Russia), while in the civil segment of the aviation industry, Russia's lagging behind is significant both in terms of the duration of projects and performance results. One of the reasons is in the poor training of aircraft engineers to work in the competitive environment. Conclusions. It is crucial to reform Russian aviation universities in terms of conformity to global trends in multidisciplinarity and differentiation of financing and research base.

Abstract Big data analytics (BDA) in e-commerce, which is an emerging field that started in 2006, deeply affects the development of global e-commerce, especially its layout and performance in the U.S. and China. This paper seeks to examine the relative influence of theoretical research of BDA in e-commerce to explain the differences between the U.S. and China by adopting a statistical analysis method on the basis of samples collected from two main literature databases, Web of Science and CNKI, aimed at the U.S. and China. The results of this study help clarify doubts regarding the development of China’s e-commerce, which exceeds that of the U.S. today, in view of the theoretical comparison of BDA in e-commerce between them.

In September 2015, VW had admitted to United States regulators that it had deliberately installed “defeat devices” in many of its diesel cars, which enabled the cars to cheat on federal and state emissions tests, making them able to pass the tests and hit ambitious mileage and performance targets while actually emitting up to 40 times more hazardous gases into the atmosphere than legally allowed. The discovery had prompted the U.S. Environmental Protection Agency (EPA) to halt final certification of VW’s 2016 diesel models, and VW itself had halted sales of its 2015 models. As fallout from the defeat devices developed, VW posted its first quarterly loss in more than 15 years, and its stock plummeted. Top executives were replaced, and VW abandoned its goal of becoming the world’s largest automaker. Stakeholders around the world had been asking since the scandal broke: “How could this have happened at Volkswagen?”

Information technology such as electronic medical records (EMRs), electronic prescribing, and clinical decision support systems are recognized as essential tools in all developed countries. However, the U.S. lags significantly behind other countries that are members of the Organization for Economic Cooperation and Development (OECD). Significant barriers impede wide-scale adoption of these tools in the U.S., especially EMR systems. These barriers include lack of access to capital by healthcare providers, complex systems, and lack of data standards that permit exchange of clinical data, privacy concerns and legal barriers, and provider resistance. Overcoming these barriers will require subsidies and performance incentives by payers and government, certification and standardization of vendor applications that permit clinical data exchange, removal of legal barriers, and convincing evidence of the cost-effectiveness of these IT applications.

This chapter uses innovation theory to provide both a general theoretical critique and a selective empirical critique of the use of agency theory to rationalize the looting of the U.S. business corporation as enhancing economic efficiency. It focuses on three empirical works, Bebchuk and Fried, Pay Without Performance (2004); Bebchuk, Brav, and Jiang, “The Long-Term Effects of Hedge-Fund Activism” (2015); and Fried and Wang, “Short-Termism and Capital Flows” (2017). The chapter contends that MSV ideology as promulgated by agency theorists has contributed to inferior corporate and economic performance. It then argues that, for analyzing the operation and performance of the economy, innovation theory should replace agency theory.
