Synthesis and Characterization of Multilayered Diamond Coatings for Biomedical Implants
Leigh Booth,Shane A. Catledge,Dustin Nolen,Raymond G. Thompson,Yogesh K. Vohra
Materials , 2011, DOI: 10.3390/ma4050857
Abstract: With incredible hardness and excellent wear-resistance, nanocrystalline diamond (NCD) coatings are gaining interest in the biomedical community as articulating surfaces of structural implant devices. The focus of this study was to deposit multilayered diamond coatings of alternating NCD and microcrystalline diamond (MCD) layers on Ti-6Al-4V alloy surfaces using microwave plasma chemical vapor deposition (MPCVD) and validate the multilayer coating’s effect on toughness and adhesion. Multilayer samples were designed with varying NCD to MCD thickness ratios and layer numbers. The surface morphology and structural characteristics of the coatings were studied with X-ray diffraction (XRD), Raman spectroscopy, and atomic force microscopy (AFM). Coating adhesion was assessed by Rockwell indentation and progressive load scratch adhesion tests. Multilayered coatings shown to exhibit the greatest adhesion, comparable to single-layered NCD coatings, were the multilayer samples having the lowest average grain sizes and the highest titanium carbide to diamond ratios.
Compromise in CDMA Network Planning  [PDF]
Stephen Hurley, Leigh Hodge
Communications and Network (CN) , 2010, DOI: 10.4236/cn.2010.23023
Abstract: CDMA network planning, for example in 3G UMTS networks, is an important task whether for upgrading existing networks or planning new networks. It is a time consuming, computationally hard, task and generally requires the consideration of both downlink and uplink requirements. Simulation experiments presented here suggest that if time is a major consideration in the planning process then as a compromise only uplink needs to be considered.
The Utility of MMPI-2 Scores with a Correctional Population & Convicted Sex Offenders  [PDF]
Brianna Leigh Grover
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.26098
Abstract: The MMPI-2 is a widely used objective personality measure across all settings. It is especially useful in correctional settings due to its objectivity with standardized administration and scoring This helps aid many factors including volume, legal accountability, the nature of the clientele, and the need for security. Since assessments provide very useful information about prisoners for correctional staff, these factors make the MMPI-2 a very valuable test to use in prison. Studies have found no significant differences between African Americans and Caucasians, however have found subtle differences between MMPI-2 scores of males and female offenders. One specific area the MMPI-2 has been used for in prison is with sex offenders. Previous studies have aimed to use the MMPI-2 to identify high and low risk sex offenders, as well as differentiate between general sex offenders and internet sex offenders. Not only has it been used to identify certain sex offenders, it has been used in examining the predictors of completion of sex offender treatment programs.
Trade Liberalization, Import Penetration and Unionization: The U.S. Experience  [PDF]
Ayfer Gurun, G. Geoffrey Booth
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.61010
Abstract: In the aftermath of World War II there has been a worldwide trend for countries to pursue policies to enhance free trade in order to improve their economic wellbeing. Nevertheless the benefits are associated with free trade and many generate unwanted consequences to segments of a nation’s populace. With this thought in mind, we investigate the impact of import penetration originating from low-wage countries on the unionization rates in U.S. We find that import penetration originating from low-wage countries decreases unionization rates, with a 1% increase in import penetration reducing unionization rates by slightly less than 2% within three years after controlling for several factors that may affect unionization rates. If only imports from China and India (both low-wage countries) are considered, the reduction almost doubles. Our findings are consistent with the argument that firms are reluctant to collaborate and contract with unions that ask for sticky labor costs and multiyear contracts because these provisions often result in declining profit margins.
Feminism Ain’t Funny: Woman as “Fun-Killer,” Mother as Monster in the American Sitcom  [PDF]
Jack Simmons, Leigh E. Rich
Advances in Journalism and Communication (AJC) , 2013, DOI: 10.4236/ajc.2013.11001
Abstract: Whether America has realized President Herbert Hoover’s 20th-century vision of a “chicken in every pot”, there is a television in nearly every home. Powerful and accessible, television programs, whether explicitly, convey values and messages to viewers and, thus, can play a role in reifying the status quo or affecting social change. Given comedy programming’s roots in radio and Vaudeville, it is no surprise that a recurrent theme in situational comedies is the “war between the sexes”. Despite a surfeit of studies examining specific programs, however, there exists no comprehensive project exploring how gender depictions have changed since television’s proliferation in post-WWII America. This time span is especially important because it is bisected by second wave feminism. Regarding gender, TV shows need not fortify traditional ideals. But how far has television come? Findings from a pilot study employing a Grounded Theory analysis of selected US sitcoms from 1952 to 2004 suggest that, regardless of the progressive nature of some programming, the most-watched sitcoms reaffirm mainstream stereotypes of women. What has changed, however, is the hierarchical relationship between the sexes. While sitcoms have modified roles of women in an effort to keep up with changing social norms, they have failed to meaningfully alter traditional masculine narratives. What has been won is a superficial role reversal: Where once television women were childlike subordinates to their male counterparts, now men are depicted as irresponsible children women must mother and discipline.
El Estado Ausente: la paradójica configuración balnearia del Gran Valparaíso (1850-1925)
EURE (Santiago) , 2002, DOI: 10.4067/S0250-71612002008300007
Abstract: since the second half of the 19th century, the state?s marked preference for the industrialization of the coast of valparaíso caused the dislodging of the first sea resorts in the bay. at the same time, private investors had settled their sea resorts in the recently created village of vi?a del mar. however, their investment was not able to modify vi?a?s paradoxical condition of an inland-facing village until the early 20th century. this contradictory condition is explained by the lack of state interest in the promotion of hedonistic uses of chile?s central coast. only the combined action of both public and private intervention permitted a progressive re-orientation of vi?a del mar towards the coast. this was decisive in establishing its future configuration as a city centered on tourism around sea resorts.
Splitting, splitting and splitting again: A brief history of the development of regional government in Indonesia since independence
Anne Booth
Bijdragen tot de Taal-, Land- en Volkenkunde , 2011,
Abstract: The paper reviews the changes in the structure and role of provincial and sub-provincial governments in Indonesia since independence. Particular attention is paid to the process of splitting both provinces and districts (kabupaten and kota) into smaller units. The paper points out that this process has been going on since the 1950s, but has accelerated in the post-Soeharto era. The paper examines why the splitting of government units has occurred in some parts of the Outer Islands to a much greater extent than in Java, and also examines the implications of developments since 1999 for the capacity of local government units to deliver basic services such as health and education.
"El paisaje aquí tiene un encanto fresco y poético". Las bellezas del sur de Chile y la construcción de la nación turística
Rodrigo Booth
HIb Revista de Historia Iberoamericana , 2010,
Abstract: This article examines the role that tourism has played in the establishment of a consensus that the south of Chile is thought of as being a beautiful place.The focus of this work is from the perspective of tourists, who over the first half of the twentieth century redefined the old and mysterious “araucanian jungle” and transformed it into what became known as “Chile’s Switzerland.” The article argues that the tourist activity of the people who visited the araucanian and lakeregions contributed to the establishment of new ways of viewing the territory,constructing a sense of pride for the aesthetic values of nature. This “landscape nationalism”, which was shared across all ideological perspectives, became an aspect of central importance for contemporary Chilean identity.

China’s Economic Relations with Indonesia: Threats and Opportunities
Anne Booth
Journal of Current Southeast Asian Affairs , 2011,
Abstract: The paper examines the development of China’s economic ties with Southeast Asia over the last two decades, culminating in the inauguration of the ASEAN-China Free Trade Agreement (ACFTA) in 2010. Particular reference is made to China’s trade ties with Indonesia. Although two-way trade between China and Indonesia has grown rapidly since 2000, Indonesian exports to China are dominated by primary products, while imports from China are dominated by manufactures. While this pattern might reflect short-term comparative advantage in both economies, it is causing some concern in Indonesia. The paper assesses these concerns, and possible political reactions.
