British Imperial Air Power: The Royal Air Forces and the Defense of Australia and New Zealand Between the World Wars

British Imperial Air Power examines the air defense of Australia and New Zealand during the interwar period. It also demonstrates the difficulty of applying new military aviation technology to the defense of the global Empire and provides insight into the nature of the political relationship between the Pacific Dominions and Britain. Following World War I, both Dominions sought greater independence in defense and foreign policy. Public aversion to military matters and the economic dislocation resulting from the war and later the Depression left little money that could be provided for their respective air forces. As a result, the Empire’s air services spent the entire interwar period attempting to create a strategy in the face of these handicaps. In order to survive, the British Empire’s military air forces offered themselves as a practical and economical third option in the defense of Britain’s global Empire, intending to replace the Royal Navy and British Army as the traditional pillars of imperial defense.https://docs.lib.purdue.edu/purduepress_previews/1054/thumbnail.jp

Using Noninvasive Brain Measurement to Explore the Psychological Effects of Computer Malfunctions on Users during Human-Computer Interactions

In today’s technologically driven world, there is a need to better understand the ways that common computer malfunctions affect computer users. These malfunctions may have measurable influences on computer user’s cognitive, emotional, and behavioral responses. An experiment was conducted where participants conducted a series of web search tasks while wearing functional nearinfrared spectroscopy (fNIRS) and galvanic skin response sensors. Two computer malfunctions were introduced during the sessions which had the potential to influence correlates of user trust and suspicion. Surveys were given after each session to measure user’s perceived emotional state, cognitive load, and perceived trust. Results suggest that fNIRS can be used to measure the different cognitive and emotional responses associated with computer malfunctions. These cognitive and emotional changes were correlated with users’ self-report levels of suspicion and trust, and they in turn suggest future work that further explores the capability of fNIRS for the measurement of user experience during human-computer interactions

The LightSail 2 Controlled Solar Sailing Demonstration Mission

The LightSail 2 mission is the culmination of a decade-long program sponsored by The Planetary Society to advance solar sailing technology. The objective of LightSail 2 is to demonstrate controlled solar sailing in Earth orbit using a CubeSat platform. The LightSail 2 attitude is controlled using a single-axis momentum wheel and magnetic torque rods. During solar sailing operations, two 90 degree slews are performed each orbit to harness momentum from solar photons. Flight data show that LightSail 2 is successfully controlling its orientation relative to the Sun, and the controlled thrust from solar radiation pressure is measurably reducing the rate of orbital decay. The Planetary Society declared LightSail 2 mission success on July 31, 2019. This paper provides an overview of the LightSail 2 mission implementation, including the design of the flight system and flight software, and the pre-launch testing program. A summary of LightSail 2 mission operations is provided, including a description of the ground system. Solar sailing performance is presented, and anomalies encountered during the mission are discussed. The flight team continues to refine solar sailing performance and conduct on-orbit imaging for engineering purposes and to engage public interest. The LightSail program is entirely donor-funded, with over 50,000 contributors around the globe

Pleiotropic effects of simvastatin and losartan in preclinical models of post-traumatic elbow contracture

Elbow trauma can lead to post-traumatic joint contracture (PTJC), which is characterized by loss of motion associated with capsule/ligament fibrosis and cartilage damage. Unfortunately, current therapies are often unsuccessful or cause complications. This study aimed to determine the effects of prophylactically administered simvastatin (SV) and losartan (LS) in two preclinical models of elbow PTJC: a

"It is what it is": masculinity, homosexuality, and inclusive discourse in mixed martial arts

In this paper we make use of inclusive masculinity theory to explore online media representations of male homosexuality and masculinity within the increasingly popular combat sport of mixed martial arts MMA). Adopting a case-study approach, we discuss narratives constructed around one aspirational male MMA fighter, Dakota Cochrane, whose history of having participated in gay pornography became a major talking point on a number of MMA 'fanzine'/'community' websites during early 2012. While these narratives attempted to discursively 'rescue' Cochrane's supposedly threatened masculinity, highlighting both his 'true' heterosexuality and his prodigious fighting abilities, they also simultaneously celebrated the acceptance of homosexual men within the sport which Cochrane's case implied. Thus, we suggest that these media representations of homosexuality and masculinity within MMA are indicative of declining cultural homophobia and homohysteria, and an inclusive vision of masculinity, as previously described by proponents of inclusive masculinity theory
