The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

The purpose of this paper is to investigate the knock combustion characteristics, including the combustion pressure, heat release rate (HRR) and knock intensity of aviation kerosene fuel, that is, Rocket Propellant 3 (RP-3), on a port-injected two-stoke spark ignition (SI) engine.

Experimental investigation using a bench test and the statistical analysis of data to reflect the knock combustion characteristics of the two-stroke SI unmanned aerial vehicle (UAV) engine on RP-3 kerosene fuel.

Under the full load condition of 4,000 rpm, at the ignition timing of 25 degree of crank angle (°CA) before top dead centre (BTDC), the knock combustion is sensitive to the thinner mixture; therefore, the knock begins to occur when the excess air ratio is larger than 1.0. When the excess air ratio is set as 1.2, the knock obviously appears with the highest knock intensity. At the excess air ratio of 1.2, better engine performance is obtained at the ignition timing range of 20-30 °CA BTDC. However, the ignition timing at 30° CA BTDC significantly increases the peak combustion pressure and knock intensity with the advancing heat release process.

Gasoline has a low flash point, a high-saturated vapour pressure and relatively high volatility, and it is a potential hazard near a naked flame at room temperature, which can create significant security risks for its storage, transport and use. The authors adopt a low-volatility single RP-3 kerosene fuel for all vehicles and equipment to minimise the number of different devices using various fuels and improve the military application safety.

Most two-stroke SI UAV engines for military applications burn gasoline. A kerosene-based fuel for stable engine operation can be achieved because the knock combustion can be effectively suppressed through the combined adjustment of the fuel amount and spark timing.

This research draws on qualitative interviews with primarily lower socioeconomic status (SES) public library internet users to illuminate their perceptions of economic benefits afforded by the internet. This powerful evidence challenges utopian new technological theories. The results from this study allow for the comparison of perspectives from Millennials, Generation Xers, Boomers, and the Silent generation. These results suggest a disconnect between the cultural mythology around the internet as an all-powerful tool and the lived experiences of lower SES respondents. Lower SES participants primarily use the internet to train and educate themselves in areas where they would like to work in the process of applying for jobs using the internet. Participants recognized marginal benefits such as socialization and less burdensome job application processes. However, they struggled to identify significant job-related benefits when comparing applying for jobs online as opposed to applying for jobs in person. With the exception of millennials, all generational groups believed in the economic promise of the internet to make their lives easier given enough time. Millennials, however, challenged the techno-utopianism expressed by other generations. Only millennials recognized the realities of digital inequalities that make techno-utopian outcomes unattainable given broader economic realities for low-SES individuals.

This chapter offers an historical overview and analysis of US broadcast regulation. It demonstrates how seemingly race-neutral policies – the interpretation of “public interest,” the preference for incumbents, the application of the First Amendment, and the embrace of colorblindness within US media policy – has functioned to entrench White interests in the broadcasting sector. Drawing on critical policy studies and critical race theory, this chapter illuminates how broadcast regulation has been a technology of White privilege, one that has had substantial consequences for the distribution of both material and symbolic resources as well as for the contours of the public sphere in the United States.

Efforts to make the television landscape more equitable for people of color have been evident both within and outside the industry as early as the 1940s. These advancements made by individuals within broadcasting were an attempt to allow more people of color to get opportunities to prove themselves competent in front of and behind the scenes in broadcast television. While these early attempts were ultimately unsuccessful, they laid the groundwork for future diversity initiative efforts. The purpose of this chapter is to expose the landmark events that introduced changes in diversity policy that eventually resulted from diversity initiatives at NBC despite the racial barriers within its corporate structure. This chapter will show that the trajectory of these early events exhibits that the diversity initiatives seen today resulted from decades of pressure from the government, the press and outside citizen activist groups.

This paper reports on the introduction of major change into a large group of hospitals. While the study acknowledges the need to cater for technological, structural and personnel aspects during the change process it concentrates on the human element. This is because it is the least predictable, and arguably the most critical, factor involved ‐ particularly in a hospital setting where key actors are subject to the potentially opposing pulls of organisational and professional membership.
