How the Tea Party Captured the GOP Insurgent Factions in American Politics

Blum’s work provides a strong starting point to understand how factions can have a lasting impact on parties. Still, this work offers a theoretical framework to understand how insurgent factions such as the Tea Party can have a lasting effect on the Republican Party. This book review analyzes Blum’s work and provides analysis and gentle criticisms of this work. The Tea Party successfully renegotiated the ideological positions of the Republican Party by using confrontational tactics and challenging established GOP candidates. Through these insurgent tactics, the Tea Party reshaped the Republican Party to embrace reactionary conservatism. This transformation of the Republican Party created a receptive base of voters for candidates like Donald Trump

The Feasibility of a Conditional Cash Transfer Program in Pittsburgh

This policy paper recommends that Pittsburgh develop a small-scale pilot Conditional Cash Transfer (CCT) program. My research examines the local dynamics of poverty in Pittsburgh, and critics the poverty reduction strategies currently utilized. An analysis of the political barriers facing a proposed CCT program in Pittsburgh is included, and a political strategy concerning the development of a local CCT program is presented

An Information Theoretic Approach to Content Based Image Retrieval.

We propose an information theoretic approach to the representation and comparison of color features in digital images to handle various problems in the area of content-based image retrieval. The interpretation of color histograms as joint probability density functions enables the use of a wide range of concepts from information theory to be considered in the extraction of color features from images and the computation of similarity between pairs of images. The entropy of an image is a measure of the randomness of the color distribution in an image. Rather than replacing color histograms as an image representation, we demonstrate that image entropy can be used to augment color histograms for more efficient image retrieval. We propose an indexing algorithm in which image entropy is used to drastically reduce the search space for color histogram computations. Our experimental tests applied to an image database with 10,000 images suggest that the image entropy-based indexing algorithm is scalable for image retrieval of large image databases. We also proposed a new similarity measure called the maximum relative entropy measure for comparing image feature vectors that represent probability density functions. This measure is an improvement of the Kullback-Leibler number in that it is non-negative and satisfies the identity and symmetry axioms. We also propose a new usability paradigm called Query By Example Sets (QBES) that allows users, particularly novice users, the ability to express queries in terms of multiple images

Estimating the extra costs of disability in European countries: Implications for poverty measurement and disability-related decommodification

It is widely accepted that people with disabilities incur additional expenditures on transport, heating, equipment and other items. In this article, we estimate the magnitude of these extra costs of living for adults with disabilities aged 50–65 across 15 countries of Europe using the Survey of Health, Aging, and Retirement in Europe (SHARE) data. Drawing on the standard of living approach of Zaidi and Burchardt, we compare the incomes required by households with and without adults with disabilities to obtain an equivalent standard of living. We advance upon this research by drawing on the cross-nationally harmonized data of adults aged 50+ from the SHARE. The results suggest that there are substantial extra costs of disability in these countries: around 44 percent of income for a household with an adult reporting a work-related disability and somewhat less than 30 percent of income for a household with an adult who receives disability benefits. Applying an equivalization scale based on these figures increases the overall poverty incidence rate, especially for households with disabled adult members. These findings thus have implications for analysing the entitlement and benefit levels for disability support programmes and for devising accurate poverty estimates concerning persons with disabilities

Low-speed aerodynamic characteristics of a twin-engine general aviation configuration with aft-fuselage-mounted pusher propellers

An investigation was conducted to determine the aerodynamic characteristics of an advanced turboprop aircraft model with aft-pylon-mounted pusher propellers. Tests were conducted through an angle-of-attack range of -8 to 28 degrees, and an angle-of-sideslip range of -20 to 20 degrees at free-stream conditions corresponding to Reynolds numbers of 0.55 to 2.14 x 10 to the 6th power based on mean aerodynamic chord. Test results show that for the unpowered configurations the maximum lift coefficients for the cruise, takeoff, and landing configurations are 1.45, 1.90, and 2.10, respectively. Nacelle installation results in a drag coefficient increase of 0.01. Increasing propeller thrust results in a significant increase in lift for angles of attack above stall and improves the longitudinal stability. The cruise configuration remains longitudinally stable to an angle of attack 5 degrees beyond the stall angle, the takeoff configuration is stable 4 degrees beyond stall angle, and the landing configuration is stable 3 degrees beyond stall angle. The predominant effect of symmetric thrust on the lateral-directional aerodynamic characteristics is in the post-stall region, where additional rudder control is available with power on

Collaborative assistance from Dr David Miller (University of St Andrews) is acknowledged.A mixed-metal metal–organic framework, (Al,Ga)-MIL-53, synthesised by post-synthetic ion exchange has been investigated using solid-state nuclear magnetic resonance (NMR) spectroscopy, microscopy and energy dispersive X-ray (EDX) spectroscopy. 17O enrichment during the ion-exchange process enables site specific information on the metal distribution to be obtained. Within this work two ion-exchange processes have been explored. In the first approach (exchange of metals in the framework with dissolved metal salts), 17O NMR spectroscopy reveals the formation of crystallites with a core–shell structure, where the cation exchange takes place on the surface of these materials forming a shell with a roughly equal ratio of Al3+ and Ga3+. For the second approach (exchange of metals between two frameworks), no core–shell structure is observed, and instead crystallites containing a majority of Al3+ are obtained with lower levels of Ga3+. Noticeably, these particles show little variation in the metal cation distribution between crystallites, a result not previously observed for bulk (Al,Ga)-MIL-53 materials. In all cases where ion exchange has taken place NMR spectroscopy reveals a slight preference for clustering of like cations.Publisher PDFPeer reviewe

Funding: The authors would like to thank the ERC (Advanced Grant 787073 ADOR) and the Allan Handsel Postgraduate Research Scholarship for Chemistry for studentship funding for ZHD and EALB, respectively. We also acknowledge support from the Collaborative Computational Project on NMR Crystallography (CCP-NC) funded by EPSRC (EP/T026642/1) and from the UK Materials and Molecular Modelling Hub (Young), which is partially funded by EPSRC (EP/T022213/1, EP/W032260/1 and EP/P020194/1) for which access was obtained via the UKCP consortium and funded by EPSRC (EP/P022561/1).Compositionally complex metal-organic frameworks (MOFs) have properties that depend on local structure that is often difficult to characterise. In this paper a density functional theory (DFT) computational study of mixed-metal (Al,Sc)-MIL-53, a flexible MOF with several different forms, was used to calculate the relative energetics of these forms and to predict NMR parameters that can be used to evaluate whether solid-state NMR spectroscopy can be used to differentiate, identify and characterise the forms adopted by mixed-metal MOFs of different composition. The NMR parameters can also be correlated with structural features in the different forms, giving fundamental insight into the nature and origin of the interactions that affect nuclear spins. Given the complexity of advanced NMR experiments required, and the potential need for expensive and difficult isotopic enrichment, the computational work is invaluable in predicting which experiments and approaches are likely to give the most information on the disorder, local structure and pore forms of these mixed-metal MOFs.Publisher PDFPeer reviewe
