The mid-infrared is a promising region for detection different materials. Many vibrational modes, including bending and stretching, are located in this regime. Photothermal spectroscopy and imaging in the mid-infrared region is an emerging new method for non-contact detection of molecular groups. Our approach to photothermal spectroscopy and imaging utilizes a near-infrared erbium doped fiber laser (EDFL) to detect the photothermal induced changes in the refractive index. These changes are excited by a mid-infrared quantum cascade laser (QCL) pump beam. The probe beam is detected by a commercially available near-infrared photodetector. This method has advantages of high sensitivity, label-free detection, high spatial resolution and high signal-to-noise ratio (SNR). Hydrogels such as pHEMA are polymers that are of interest for contact lens, drug delivery and soft tissue replacement. The pHEMA hydrogel can retain water content, causing the material to swell. Additionally, pHEMA has a critical temperature at which the hydrogel undergoes a glass transition. Photothermal spectroscopy of pHEMA is demonstrated in this thesis where the presence of this glass transition temperature can be revealed. Additionally, photothermal imaging of a PMMA USAF target sample is shown and ideal parameters for high-resolution photothermal imaging are determined. In this thesis, we report a spatial resolution much smaller than the diffraction limited spot size of the mid-infrared beam. / 2018-07-09T00:00:00Z

This thesis explores how the local media in East Anglia portrayed the US military presence during the Cold War at times of international crisis. It aims to assess this portrayal in comparison with national media images and critically interrogates the socio-political, economic and cultural reasons for it. This media related study contributes to Cold War historiography and the historiography of the USAF. Research was mainly archival, based on discourse analysis and comparative focusing on the official discourse of the Cold War and the news media. Central to the research were the written records of the British government and articles in appropriate newspapers issued near American airbases. The region of East Anglia was selected for its strategic location and large number of military bases, and data collection focused on selected periods of international crisis due to their impact on media coverage. The examination of newspaper articles identified a wide range of images with some recurring from time to time while others remain specific to certain periods. Findings suggest that local economic as well as political interests played a role in shaping the images of the US presence in the local media, and it could be argued that there is a correlation between the conservative landscape of the region and the newspaper articles’ overwhelming tolerance or at least acceptance of the US presence, which is in line with conservative governmental discourse in all periods of crisis explored. However, the articles – and in particular the readers’ letters to the editors – also highlight that there were strong debates between supporters and opponents of the American presence, and this debate blurs the boundaries of political parties, i.e. in certain periods there are also strong opponents in the conservative camp.

Bombningen av Dresden är en av andra världskriget mest kontroversiella nyttjanden av luftstridskrafterna från den allierade sidan. Vissa argumenterade för att Dresden var ett civilt mål utan militärt eller strategiskt värde. Syftet med den här uppsatsen är att analysera Dresden som mål för de allierade luftstridskrafterna ur Giulio Douhet och John A.Warden IIIs luftmaktsteorier. Undersökningen bär mot att analysera hur och om man kan motivera Dresden som ett militärt och strategiskt mål ur två olika luftmakteoriers perspektiv. Uppsatsen genomförs med en kvalitativ innehållsanalys och komparativ analys för att jämföra teorierna med fallet. Resultatet av undersökningen visar hur man kan motivera Dresden som militärt och strategiskt mål. Warden och Douhets teorier är användbara för att analysera bombningen av Dresden. / The bombing of Dresden is one of the most controversial actions carried out by the allied air forces during World War 2. Some argue that Dresden was a civilian target, without strategic or military value. The purpose of this essay is to analyse Dresden as a target for the allied air forces using Giulio Douhets and John A. Warden IIIs theories of the use of air forces. This essay aims to investigate if and how one can justify Dresden as a military and strategic target by using Douhets and Wardens theories. The essay is conducted through qualitative content analysis and comparative analysis to compare the theories with case. The result shows how one can justify the bombing of Dresden using Douhets and Wardens theories.

Operation Rolling Thunder was a United States led operation, with the political aims of interdicting and preventing the North Vietnamese support of the South Vietnam rebellion, during the later stage of the Vietnam war. Despite being a superpower, Operation Rolling Thunder failed, and the USA lost the war. In this essay, the air power theorists John A. Warden and Robert A. Pape, and their theories regarding how air power should be used to reach success, are used to analyze this failure. The use of these theories in a parallel manner enables to comprehend empirical sources and in turn recognize anomalies in the decision making and missteps of the American leadership. By keeping the case of Rolling Thunder in focus and thereby try and understand what happened, the aim is to create an understanding for why the potent power of the US Air Force made an inadvertent turn despite exercising air superiority throughout most of the operation. This examination concludes that there were three deciding factors in the American failure, which are: (i) absence of efficient attacks against the North Vietnamese leadership, (ii) lack of correlation between strategy and political aim, (iii) lack of experience and communication within the American leadership.

The study examined the effects of a study skills training intervention course on U.S. Air Force Aeromedical Apprentices with five main purposes. The first was to examine the relationship between study skills training and the number of times students required academic interventions outside of normal class time. The second purpose was to examine the relationship between study skills training and end of course averages. The third was to determine the relationship between study skills training and the amount of additional instruction, measured in time, students required. The fourth purpose examined the relationship between study skills training and graduation rates. The final purpose was to recommend areas for further research.

As experienced fighter pilots leave the United States Air Force (USAF) and Royal Australian Air Force (RAAF), there is a need to develop new competent pilots to meet national defense requirements. Fighter training programs are expensive for taxpayers, and the USAF and RAAF face significant resource problems developing and implementing these programs. Using policy feedback theory and punctuated equilibrium theory as the theoretical foundation, the purpose of this comparative, multi-case study of current USAF F-16 and RAAF F-18 fighter pilot training policies was to inform training policy development and efficacy of future USAF and RAAF fighter pilot training programs. Data were gathered from training policy documents and 12 interviews with F-16 and F-18 pilots. Data were deductively coded and analyzed using policy feedback and punctuated event themes. Findings indicate that policy feedbacks and punctuated events influence fighter pilot training policy. Best practices for training include optimum stress management, appropriate academic course timing, and phase-based training techniques. Optimal instructional approaches included a servant leadership philosophy and a need for improved kinesthetic flight preparation tools and procedures. The USAF and RAAF approach fighter pilot training differently. The positive social change implications stemming from this study include recommendations to the USAF and RAAF that may improve fighter pilot training policy at the lowest possible cost to the taxpayers.
