In a world that is increasingly united in time and distance, I examine why the world is increasingly divided socially, economically, and digitally. Using data for 35 variables from 93 countries, I separate the countries into groups of 31 each by gross domestic product per capita. These groups of developed, lesser developed and least developed countries are used in comparative analysis. Through a review of relevant literature and tests of bivariate correlation, I select eight key variables that are significantly related to information communication technology development and to human development. For this research, adoption of the Internet in the developing world is the innovation of particular interest. Thus, for comparative purposes, I chose Internet Users per 1000 persons per country and the Human Development Index as the dependent variables upon which the independent variables are regressed. Although small in numbers among the least developed countries, I find Internet Users as the most powerful influence on human development for the poorest countries. The research focuses on key obstacles as well as variables of opportunity for Internet usage in developing countries. The greatest obstacles are in fact related to Internet availability and the cost/need ratio for infrastructure expansion. However, innovations for expanded …

Torpedograss (Panicum repens) was first observed in Lake Okeechobee in the 1970s and appears to have displaced an estimated 6,400 ha of native plants, such as spikerush (Eleocharis cellulosa), where inundation depths are often less than 50 cm. Two series of studies evaluated substrate exposure and water depth influences on torpedograss establishment and competitiveness. Results revealed that fragments remain buoyant for extended periods and so facilitate dispersal. Once anchored to exposed substrate fragments can readily root and establish. Subsequently, torpedograss thrives when subjected to inundations to 75 cm and survives prolonged exposure to depths greater than 1 m. These findings suggest that fluctuating water levels contribute to torpedograss dispersal and colonization patterns and that low water levels increase marsh area susceptible to invasion. The competition study found that spikerush grown in monoculture produces significantly more biomass when continually inundated to shallow depths (10 to 20 cm) than when subjected to drier conditions (-25 cm) or greater inundations (80 cm). In contrast, torpedograss establishes more readily on exposed substrate (-25 to 0 cm) compared to inundate substrates. During the first growing season biomass production increases as substrate exposure interval increases. However, during the second year, established torpedograss produces more biomass when …

Quinoxaline-functionalized, cage-annulated oxa- and thiacrown ethers have been synthesized as possible specific metal host systems. The synthesis and characterization of quinoxaline-functionalized, cage-annulated oxa- and thiacrown ethers have been described. The characterization of these host systems have been fully achieved in solution by using various techniques such as IR, 1H NMR, and 13C NMR spectroscopic methods, high-resolution mass spectrometry (HRMS), elemental microanalysis, and X-ray crystallographic analysis in case of one quinoxaline-functionalized, cage-annulated oxacrown ether compound. The synthesis of the diphosphine ligand 2,3-bis(diphenylphosphino)-N-p-tolylmaleimide (bmi) is described. The substitution of the MeCN ligands in the activated cluster 1,2-Os3(CO)10(MeCN)2 by the diphosphine ligand bmi proceeds rapidly at room temperature to furnish a mixture of bridging and chelating Os3(CO)10(bmi) isomers and the ortho-metalated product HOs3(CO)9[μ-(PPh2)C=C{PPh(C6H4)}C(O)N(tolyl-p)C(O)]. Thermolysis of the bridging isomer 1,2-Os3(CO)10(bmi) under mild conditions gives the chelating isomer 1,1-Os3(CO)10(bmi), whose molecular structure has been determined by X-ray crystallography. The kinetics for the ligand isomerization have been investigated by UV-vis and 1H NMR spectroscopy in toluene solution over the temperature range of 318-348 K. On the basis of kinetic data conducted in the presence of added CO and the Eyring activation parameters, a non-dissociative phosphine migration across one of the Os-Os bonds is proposed. Orthometalation of …

The United States Marine Corps and the United States Navy developed during the interwar period a doctrine that addressed the problems inherent in the substitution of naval gunfire for artillery support in an amphibious assault. The invasion of Betio Islet, Tarawa Atoll, in November of 1943 was the first test of this doctrine. It has been said many times since the war that the doctrine basically passed this test and that lessons learned at Tarawa increased the efficiency with which the Marine Corps and Navy applied the prewar doctrine during the rest of the war. An analysis of the planning and execution of naval bombardments in the Central Pacific Campaign, after the invasion of the Gilberts, does not support this claim. This analysis leads the researcher to three conclusions. First, the Japanese developed defenses against many of the effects of the gunfire support doctrine that blunted much of the force of American firepower. American planners were slow to recognize the implications of these changes and, consequently, were slow to react to them. Second, many naval commanders responsible for providing naval gunfire support for Central Pacific operations still equated tonnage of ordnance to effectiveness of bombardment, regardless of their frequent references …

Whether provided by a composer, written out by a performer or completely improvised, the cadenza became a vehicle for performers' creativity, lyricism and technical prowess in the eighteenth and nineteenth centuries. The debate about whether to notate or improvise cadenzas, a question as old as the cadenza itself, continues today. Saxophonists have not been involved in this debate, since the instrument is a product of the mid-nineteenth century and was in its infancy just as the practice of improvising cadenzas was fading. This study documents an unprecedented, recently-recorded, improvised cadenza in one of the most significant twentieth-century saxophone works: Jacques Ibert's Concertino da Camera for Alto Saxophone and Eleven Instruments (1935). Saxophonist Branford Marsalis's neo-cadenza for Ibert's composition presents an aggregate of the twenty-first-century performer improvising a cadenza to a twentieth-century work, in a tradition that was common centuries ago. The document begins with an inquiry into improvised cadenzas, and proceeds to an examination of the performance history of the cadenza for the Concertino da Camera. Twenty professionally-recorded versions of the cadenza are presented in order to understand the performance history of the cadenza, and to place the Marsalis cadenza into context. This research culminates in a transcription and analysis …

The Internet and networks in general have become essential tools for disseminating in-formation. Search engines have become the predominant means of finding information on the Web and all other data repositories, including local resources. Domain scientists regularly acquire and analyze images generated by equipment such as microscopes and cameras, resulting in complex image files that need to be managed in a convenient manner. This type of integrated environment has been recently termed a netcentric sci-entific research repository. I developed a number of data manipulation tools that allow researchers to manage their information more effectively in a netcentric environment. The specific contributions are: (1) A unique interface for management of data including files and relational databases. A wrapper for relational databases was developed so that the data can be indexed and searched using traditional search engines. This approach allows data in databases to be searched with the same interface as other data. Fur-thermore, this approach makes it easier for scientists to work with their data if they are not familiar with SQL. (2) A Web services based architecture for integrating analysis op-erations into a repository. This technique allows the system to leverage the large num-ber of existing tools by wrapping them …

The characterization, properties and applications of the novel nanostructured microgel (nanoparticle network and microgel crystal) composed of poly-N-isopropylacrylanmide-co-allylamine (PNIPAM-co-allylamine) and PNIPAM-co-acrylic acid(AA) have been investigated. For the novel nanostructured hydrogels with the two levels of structure: the primary network inside each individual particle and the secondary network of the crosslinked nanoparticles, the new shear modulus, drug release law from hydrogel with heterogeneous structure have been studied. The successful method for calculating the volume fraction related the phase transition of colloid have been obtained. The kinetics of crystallization in an aqueous dispersion of PNIPAM particles has been explored using UV-visible transmission spectroscopy. This dissertation also includes the initial research on the melting behavior of colloidal crystals composed of PNIPAM microgels. Many new findings in this study area have never been reported before. The theoretical model for the columnar crystal growth from the top to bottom of PNIPAM microgel has been built, which explains the growth mechanism of the novel columnar hydrogel colloidal crystals. Since the unique structure of the novel nanostructured hydrogels, their properties are different with the conventional hydrogels and the hard-sphere-like system. The studies and results in this dissertation have the important significant for theoretical study and valuable application …

The dissertation consists of the following three sections: 1. Hydroxyapatite (HA) coatings. In this work, we deposited HA precursor films from weak basic electrolytic solution (pH= 8-9) via an electrochemical approach; the deposits were changed into crystallite coatings of hydroxyapatite by sintering at specific temperatures (600-800 ºC). The formed coatings were mainly characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). XRD patterns show well-defined peaks of HA when sintered under vacuum conditions. FTIR measurements indicate the existence of hydroxyl groups, which were confirmed by the characteristic intensity of the stretching and bending bands at ~3575 and ~630 cm-1, respectively. The SEM shows an adhesive, crack free morphology for the double-layer coating surface of the samples sintered in a vacuum furnace. 2. Silver/polymer/clay nanocomposites. Silver nanoparticles were prepared in layered clay mineral (montmorillonite)/polymer (PVP: poly (vinyl pyrrolidone)) suspension by an electrochemical approach. The silver particles formed in the bulk suspension were stabilized by the PVP and partially exfoliated clay platelets, which acted as protective colloids to prevent coagulation of silver nanoparticles together. The synthesized silver nanoparticles/montmorillonite/PVP composite was characterized and identified by XRD, SEM, and TEM (transmission electron microscopy) measurements. 3. Ce-doped lead …

A rectifier is an electrical device, comprising one or more semiconductor devices arranged for converting alternating current to direct current by blocking the negative or positive portion of the waveform. The purpose of this study would be to evaluate dynamic and static electrical characteristics of rectifier chips fabricated with (a) DY8 process and (b) YI8 process and compare them with the existing DI8 process rectifiers. These new rectifiers were tested to compare their performance to meet or exceed requirements of lower forward voltages, leakage currents, reverse recovery time, and greater sustainability at higher temperatures compared to diodes manufactured using boron as base (DI8 process diodes) for similar input variables.

Recent studies reveal that a considerable number of U.S. community college leaders will be retiring in the next several years. The concern is that with the large turnover, history, culture, and important lessons of leadership will be lost. The current research on the lives of presidents, their career paths, and experiences in community college leadership centers on approaches to the study of leadership at the macro level. Limited research exists in the published literature that reports and analyzes the development of individuals as community college leaders at the micro level. This results in a gap regarding understanding leadership development and strategies to prepare leaders. This study addresses this gap by providing a critical description of the leadership development of one individual who became a community college chancellor and who the literature on the community context indicates contributed to the local and national context for community colleges. Biography is gaining prominence as a legitimate and viable tool in the study of leadership. Few biographical studies currently exist which focus on leadership development in context at the micro level. This dissertation is a biographical, qualitative study of the leadership path and legacy of R. Jan LeCroy, a community college leader. The study …

The thesis has two parts. Part I is a critical essay entitled "Lessons Under the Amfalula." Part II is the collection of poems entitled "Animals That Die."

This paper presents the lives and early feminist works of two modernist era poets, Laura Riding Jackson and Muriel Rukeyser. Despite differences of style, the two poets shared a common theme of essentialist feminism before its popularization by 1950s and 60s second wave feminists. The two poets also endured periods of poetic silence or self censorship which can be attributed to modernism, McCarthyism, and rising conservatism. Analysis of their poems helps to remedy their exclusion from the common canon.

In a 2004 study, Harvey, Lin and Roper argue that debt makers with a commitment to monitoring can create value for outside shareholders whenever information asymmetry and agency costs are pronounced. I investigate Harvey, Lin and Roper's claim for bank loans by empirically testing the effect of information asymmetry and direct agency costs on the abnormal returns of the borrowers' stock around the announcement of bank loans. I divide my study into two main sections. The first section tests whether three proxies of the direct agency costs of equity are equally significant in measuring the direct costs associated with outside equity agency problems. I find that the asset utilization ratio proxy is the most statistically significant proxy of the direct agency costs of equity using a Chow F-test statistic. The second main section of my dissertation includes and event study and a cross-sectional analysis. The event study results document significant and positive average abnormal returns of 1.01% for the borrowers' stock on the announcement day of bank loans. In the cross sectional analysis of the borrowers' average abnormal stock returns, I find that higher quality and more reputable banks/lenders provide a reliable certification to the capital market about the low …

Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits, neuromotor disturbances, and behavior problems similar to individuals with schizophrenia, and thus SPD is thought to represent one point on the continuum of schizophrenia spectrum disorders (SSDs). Deficits in behavior, cognition, and motor functioning have been implicated as childhood precursors of SSDs and appear to also vary as a function of gender and family history of psychopathology. As such, studies of youth may help in further identification of individuals at risk for SSDs. The current study examined the prospective associations between problem behaviors, neuromotor and neurocognitive functioning, as well as SSD symptoms, at baseline and 2-year follow-up in youth meeting criteria for SPD, other personality disorders, or healthy controls. The neuromotor and neurocognitive measures were able to significantly predict SSD symptoms and behavior problems above and beyond baseline predictors. Overall, the findings provide further support for the role of subcortical motor centers operating together with prefrontal cortical areas in the regulation of higher-order cognitive functioning and in producing the psychiatric features of SSDs. Significant correlations between gender, family history of schizophrenia, and history of head injury with symptoms, behavior, cognition, and motor functioning were also found and highlight …

The purpose of this study was to determine the effectiveness of the implementation of an internally created performance appraisal system as well as the subjects' overall satisfaction with the implementation. The system was implemented at a major technology consulting firm in the US. The subjects of this study were three levels of employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of employees' responses to three key questions were analyzed. Employees' perceptions of the appraisal feedback aiding increased performance, their belief about the implementation assisting with their career management, satisfaction with the initiative, and their understanding of the requirements for promotion were captured by this survey. Trend analysis indicates that employees at the firm perceived their career path knowledge unimproved, their understanding of promotion criteria unimproved as a result of the implementation. Employees did not indicate overall satisfaction with the implementation and the employee's belief about their skills and abilities utilization did not improve post implementation.

With so many paraeducators working in special education, it is important for teachers, administrators, and researchers to know how paraeducators are being utilized, supervised, and managed in order to create the most effective programs for students with special needs. Research is needed regarding current practices in supervising paraeducators. The purposes of this study were to (a) delineate the current practices being utilized by special education teachers of students with emotional and behavioral disorders (EBD) who supervise paraeducators that work with students with EBD in the general education classroom and (b) determine how effective the supervised paraeducators perceive those practices to be. Current practices were revealed by answering the following questions: (1) According to special education teachers and paraeducators, what procedures and practices are being utilized to supervise paraeducators who work in the general education environment with students with EBD? (2) In what ways do teachers and paraeducators see these supervision practices as being effective? (3) What is the relationship between actual supervision practices and accepted best practices? There were 60 participants in all, 30 professional teachers and 30 paraeducators. All 60 participants completed a survey; of these 60, 5 teachers and 5 paraeducators were individually interviewed Findings from the study …

This study examined the relationship between time of exposure to the human face and accurate subsequent photo line-up identification. A volunteer group of 124 undergraduate students was divided into three approximately equal sized subgroups. The three groups were then exposed to a video or a portion of a video depicting a theft. Exposure times ranged from two minutes to 30 seconds. The subjects were then given a questionnaire and shown a photo line-up of the mock perpetrator and five foils. Subjects were asked to identify the perpetrator and mark that identification on the questionnaire. Results of the experiment indicated that the longer a subject was exposed the greater the possibility of an accurate identification.

Death, as a subject, has been treated extensively throughout history, both in literature as well as in music. The focus of Memento mori is to portray the inevitability of death through music. The first part of the document is an essay exploring the topic of death, its inevitability, unpredictability and the fragility of life. This section also includes a number of examples of composer's whose works have influenced the composition of the piece. The title of the work is meant to reflect that death catches up with all of us and that humans no matter how invincible they feel at certain stages of life will, eventually, succumb to death. The second part of the document is the notated orchestral score. The work is for full orchestra and solo violoncello. It is in three acts that loosely resemble three stages of life; Youth followed by life in adulthood and finally death. The work is not programmatic and the piece's formal structure varies from a traditional concerto, for although comprised of three distinct acts, there are no pauses between them. The entire work is meant to be dark and morbid and the specter of death looms throughout the piece.

The emerging interests in spatial pattern mining leads to the demand for a flexible spatial pattern mining language, on which easy to use and understand visual pattern language could be built. It is worthwhile to define a pattern mining language called LCSPM to allow users to specify complex spatial patterns. I describe a proposed pattern mining language in this paper. A visual interface which allows users to specify the patterns visually is developed. Visual pattern queries are translated into the LCSPM language by a parser and data mining process can be triggered afterwards. The visual language is based on and goes beyond the visual language proposed in literature. I implemented a prototype system based on the open source JUMP framework.

The tetraruthenium cluster H4Ru4(CO)12 has been studied for its reactivity with the unsaturated diphosphine ligands (Z)-Ph2PCH=CHPPh2, 4,5-bis (diphenylphosphino)-4-cyclopenten-1,3-dione, bis(diphenyphosphino)benzene and 1,8- bis(diphenyl phosphino)naphthalene under thermal, near-UV photolysis, and Me3NO-assisted activation. All three cluster activation methods promote loss of CO and furnish the anticipated substitution products that possess a chelating diphosphine ligand. Clusters 1, 2, 3 and 4 have been characterized in solution by IR and NMR spectroscopies, and these data are discussed with respect to the crystallographically determined structures for all new cluster compounds. The 31P NMR spectral data and the solid-state structures confirm the presence of a chelating diphosphine ligand in all four new clusters. Sealed NMR tubes containing clusters 1, 2, 3 and 4 were found to be exceeding stable towards near-UV light and temperatures up to ca. 100°C. The surprisingly robust behavior of the new clusters is contrasted with the related cluster Ru3(CO)10(bpcd) that undergoes fragmentation to the donor-acceptor compound Ru2(CO)6(bpcd) and the phosphido-bridged compound Ru2(CO)6 (µ-PPh2)[µ-C=C(PPh2)C(O)CH2C(O)] under mild conditions. The electrochemical properties have been investigated in the case of clusters 1 and 2 by cyclic voltammetry, and the findings are discussed with respect to the reported electrochemical data on the parent cluster H4Ru4(CO)12.

In the world of VLSI (very large scale integration) technology, there are many different types of circuit simulators that are used to design and predict the circuit behavior before actual fabrication of the circuit. In this thesis, I compared and evaluated existing circuit simulators by considering standard benchmark circuits. The circuit simulators which I evaluated and explored are Ngspice, Tclspice, Winspice (open source) and Spectre® (commercial). I also tested standard benchmarks using these circuit simulators and compared their outputs. The simulators are evaluated using design metrics in order to quantify their performance and identify efficient circuit simulators. In addition, I designed a sigma-delta modulator and its individual components using the analog behavioral language Verilog-A. Initially, I performed simulations of individual components of the sigma-delta modulator and later of the whole system. Finally, CMOS (complementary metal-oxide semiconductor) transistor-level circuits were designed for the differential amplifier, operational amplifier and comparator of the modulator.

Although a change of religious landscape in America in recent years has been suggested and widely accepted in the social sciences, most studies tend to focus on measures of religiosity and how it is changing. The subject of spirituality and its correlates seem to be mostly ignored. This study utilizes nationally representative data generated for the first time in General Social Survey (GSS) on the subject of spirituality to measure Americans' spirituality and daily spiritual experiences and their most significant correlates. In this study, most Americans (89%) showed to have some degree of spirituality and daily spiritual experiences. Moreover, variables of gender, race/ethnicity, marital status, religious origin, and residence in conservative region when growing up shown to be significant predictors of spirituality.
