The Influence Of Poverty On The Development And Maintenance Of Conduct Disorder And Perpetuation Of Crime And Violence, David Saunders-Scott

Master's Theses and Doctoral Dissertations

Jamaica has one of the highest murder rates per capita in the world, as well as a high rate of other crimes. With this study, I examined how factors such as income, socialecological factors of poverty (S-E factors of poverty), and symptoms of conduct disorder (CD) were related to criminality in a sample of 79 male Jamaican parolees and probationers. Participants ranged in age from 18 to 74 years old and were all of African descent. I interviewed participants using the World Health Organization Composite International Diagnostic Interview (WHO-CIDI), a survey to assess S-E factors associated with poverty, and the …

Feather Meal And Rice Husk Enhanced Keratinases Production By Bacillus Licheniformis Yj4 And Characters Of Produced Keratinases, Hsin-Hung Lin, Li-Jung Yin

Journal of Marine Science and Technology–Taiwan

A feather-degrading bacterium with high keratinase activity was isolated and identified as Bacillus licheniformis YJ4. After 72 h incubation in a medium (0.5% feather meal, 0.05% NH4Cl and NaCl, 0.04% K2HPO4, 0.03% KH2PO4, 0.01% MgCl2 and yeast extract, 0.1% rice husk) at 37°C, 2 keratinases (keratinase I and II) were purified to electrophoretical homogeneity by CM sepharose and Sephadex G-75 chromatographs. They were with molecular masses (M) of 35.5 and 32.8 kDa, isoelectric point (pI) of 6.63 and 6.50, respectively, and stable at pH 6.0-10.0 and 10-50°C. The optimal pH and temperature were similar, at 9.0 and 60°C, respectively. According …

Biomarkers For Aging, Philip W. Landfield, Eric M. Blalock, Kuey-Chu Chen, Thomas S. Foster

Pharmacology and Nutritional Sciences Faculty Patents

A statistical and functional correlation strategy to identify changes in cellular pathways specifically linked to impaired cognitive function with aging. Analyses using the strategy identified multiple groups of genes expressed in the hippocampi of mammals, where the genes were expressed at different levels for several ages. The aging changes in expression began before mid-life. Many of the genes were involved in specific neuronal and glial pathways with previously unrecognized relationships to aging and/or cognitive decline. These identified genes and the proteins they encode can be used as novel biomarkers of brain aging and as targets for developing treatment methods against …

Immobilization Of Polymer-Decorated Liquid Crystal Droplets On Chemically Tailored Surfaces, Michael I. Kinsinger, Maren E. Buck, Nicholas L. Abbott, David M. Lynn

Chemistry: Faculty Publications

We demonstrate that the assembly of an amphiphilic polyamine on the interfaces of micrometer-sized droplets of a thermotropic liquid crystal (LC) dispersed in aqueous solutions can be used to facilitate the immobilization of LC droplets on chemically functionalized surfaces. Polymer 1 was designed to contain both hydrophobic (alkylfunctionalized) and hydrophilic (primary and tertiary amine-functionalized) side chain functionality. The assembly of this polymer at the interfaces of aqueous dispersions of LC droplets was achieved by the spontaneous adsorption of polymer from aqueous solution. Polymer adsorption triggered transitions in the orientational ordering of the LCs, as observed by polarized light and bright-field …

Genetic Algorithm-Based Chaos Clustering Approach For Nonlinear Optimization, Min-Yuan Cheng, Kuo-Yu Huang

Journal of Marine Science and Technology–Taiwan

In this paper, a n-dimension convergence algorithm was employed to track the potential trend of evolution in traditional genetic algorithm (GA) by K-means clustering technique. And, chaotic algorithm was exploited to prevent the new approach from premature. By means of the proposed approach, not only the basic search capability was maintained but also the flexibility and efficiency of parametric modeling were improved. The main purpose of the paper is to demonstrate how the GA optimizer can be improved by incorporating a hybridization strategy. Experimental studies revealed that the hybrid chaotic approach with genetic algorithm (CGA) procedure could produce much more …

Evaluation Of Affinity Microcolumns Containing Human Serum Albumin For Rapid Analysis Of Drug-Protein Binding, Michelle J. Yoo, John E. Schiel, David S. Hage

David Hage Publications

This study examined the use of affinity microcolumns as tools for the rapid analysis and highthroughput screening of drug-protein binding. The protein used was immobilized human serum albumin (HSA) and the model analytes were warfarin and L-tryptophan, two solutes often used as site-specific probes for drug binding to Sudlow sites I and II of HSA, respectively. The use of HSA microcolumns in binding studies was examined by using both zonal elution and frontal analysis formats. The zonal elution studies were conducted by injecting the probe compounds onto HSA microcolumns of varying lengths while measuring the resulting retention factors, plate heights …

The Desert Conservation Program administers the incidental take permit issued in 2001 by the United States Fish and Wildlife Service in accordance with the Endangered Species Act. Compliance with the permit requires implementation of the Clark County Multiple Species Habitat Conservation Plan. This plan requires an adaptive management program and a biennial report by an independent science advisor to assess the status of the plan and make recommendations for future funding. This 2010 Adaptive Management Report reviews current data on land use trends, habitat loss, species status and plan implementation, and makes recommendations for the future.

Hostility In Marital Interaction, Depressive Symptoms And Physical Health Of Husbands And Wives, Stanley D. Hall

Theses and Dissertations

The purpose of this study was to determine how hostility from either partner in a marital interaction affected marital partners' perceived general physical health, while investigating for indirect effects of partners' depression. A total of 296 married couples who participated in Waves 1 and 2 of the Flourishing Families Project were videotaped while completing a marital discussion task. Their interaction was coded for hostile behaviors using the Iowa Family Interaction Rating Scales, IFIRS. Structural equation modeling was used to examine how hostility in marital interactions at Wave 1 was related to partners' self-reports of physical health as measured by the …

Modelling Visual Neglect: Computational Insights Into Conscious Perception, Lj Lanyon, Sl Denham

School of Psychology

BACKGROUND: Visual neglect is an attentional deficit typically resulting from parietal cortex lesion and sometimes frontal lesion. Patients fail to attend to objects and events in the visual hemifield contralateral to their lesion during visual search. METHODOLOGY/PRINCIPAL FINDING: The aim of this work was to examine the effects of parietal and frontal lesion in an existing computational model of visual attention and search and simulate visual search behaviour under lesion conditions. We find that unilateral parietal lesion in this model leads to symptoms of visual neglect in simulated search scan paths, including an inhibition of return (IOR) deficit, while frontal …

Proactive Parenting Practices During Early Adolescence: A Cluster Approach, Laura M. Padilla-Walker, Katherine J. Christensen, Randal D. Day

Faculty Publications

The purpose of the current study was to explore clusters of proactive parenting practices, and how they might vary as a function of parental demographics, the quality of the parent– child relationship, and the traits and behaviors of the adolescent child. Data were taken from the Flourishing Families Project, which includes 500 families with an early adolescent child (M age ¼ 11.49). Findings suggested that there were four clusters of parents, and patterns were similar for mothers and fathers. Findings also suggested that proactive clusters varied primarily as a function of demographics of the parent (e.g., religiosity, ethnicity, education) and …

Becoming American: The Socio-Economic And Cultural Landscape Of Kenyan Immigrants In Chicago, Il, Cyril O. Wilson, Chapurukha M. Kusimba

Journal of Global Initiatives: Policy, Pedagogy, Perspective

This study reports the emerging patterns of migration and settlement of Kenyans into the Chicago metropolitan area. Like most African immigrant communities in North America, economic downturn, political instability, and socio-economic polarization in African countries necessitated an appreciable quantum of emigration of Kenyans following the attainment of Africa's political independence in the 1960s. Most of the findings on housing characteristics, education, employment, patterns of family life, socio-cultural interaction, challenges encountered by new immigrants, and related phenomena evince parallels with other studies on African immigrants in North America.

Modern Migration In Ghana And Mali: A Comparison Of Urban Migration Patterns, Dan Page, Mark W. Patterson, Kay Reeve

Journal of Global Initiatives: Policy, Pedagogy, Perspective

West Africa has a long tradition of human migration. Since the era of European colonization and during the twentieth century much of this migration has been rural to urban. This paper analyzes statistical data, observations, and interviews to compare the impacts of this migration on the cities of Bamako, Mali and Accra, Ghana. This analysis supports the conclusions that rural to urban migration in Ghana has resulted in the creation of an urban subsistence existence and an increased number of people participating in the informal sector of the economy. It further shows that when compared with Ghana, internal migration patterns …

Representation In Kenya, Its Diaspora, And Academia: Colonial Legacies In Constructions Of Knowledge About Kenya's Coast, Jesse Benjamin

Journal of Global Initiatives: Policy, Pedagogy, Perspective

This paper explores the construction of knowledge in Kenya in the context and aftermath of colonialism and underdevelopment. Those communities that were politically and economically marginalized in Coast Province over the past century were also displaced in terms of academic opportunities, resulting in fewer social science scholars from Mijikenda and other non-Swahili communities in both Kenyan and diaspora universities. Underdevelopment studies in Africa and Kenya are briefly reviewed, and the colonial history of asymmetric social relations at coastal Kenya is traced. Finally, key debates over identity and history are examined within this context and shown to be exacerbated by diasporic …

The Role Of The Kenyan Diaspora In Constructing A New Political Culture And Identity, Eric Masinde Aseka

Journal of Global Initiatives: Policy, Pedagogy, Perspective

This paper focuses on the need for and the prospects of a congenial politics of identity construction in Kenya as spearheaded by the country's diasporic communities. It identifies and interrogates the intersection of consciousness and historical experience as the basis of such identity construction. It posits the leadership function as a critical component in this process and points out how mismanagement of the African polity has led to swelling ranks of refugees. These émigrés have contributed to the making of a global Africa embodied in the Black Diaspora. This diaspora can help reconstruct the politics of identity within Kenya as …

A Probit- Log- Skew-Normal Mixture Model For Repeated Measures Data With Excess Zeros, With Application To A Cohort Study Of Paediatric Respiratory Symptoms, Sadia Mahmud, W. Y. Wendy Lou, Neil W. Johnston

Community Health Sciences

Background: A zero-inflated continuous outcome is characterized by occurrence of "excess" zeros that more than a single distribution can explain, with the positive observations forming a skewed distribution. Mixture models are employed for regression analysis of zero-inflated data. Moreover, for repeated measures zero-inflated data the clustering structure should also be modeled for an adequate analysis. Methods: Diary of Asthma and Viral Infections Study (DAVIS) was a one year (2004) cohort study conducted at McMaster University to monitor viral infection and respiratory symptoms in children aged 5-11 years with and without asthma. Respiratory symptoms were recorded daily using either an Internet …

Natural Genetic Variation In Selected Populations Of Arabidopsis Thaliana Is Associated With Ionomic Differences, Elizabeth Buescher, Tilman Achberger, Idris Amusan, Anthony Giannini, Cherie Ochsenfeld, Ana Rus, Brett Lahner, Owen Hoekenga, Elena Yakubova, Jeffrey F. Harper, Mary Lou Guerinot, Min Zhang, David E. Salt, Ivan R. Baxter

Dartmouth Scholarship

Controlling elemental composition is critical for plant growth and development as well as the nutrition of humans who utilize plants for food. Uncovering the genetic architecture underlying mineral ion homeostasis in plants is a critical first step towards understanding the biochemical networks that regulate a plant's elemental composition (ionome). Natural accessions of Arabidopsis thaliana provide a rich source of genetic diversity that leads to phenotypic differences. We analyzed the concentrations of 17 different elements in 12 A. thaliana accessions and three recombinant inbred line (RIL) populations grown in several different environments using high-throughput inductively coupled plasma- mass spectroscopy (ICP-MS). Significant …

Language As A Predictor Of Reticence In Children With Language Impairment, Patricia Anne Moses

Theses and Dissertations

This study examined the relationship between language skills and reticence in 37 children with language impairment (LI) and 37 typically developing peers matched for age (ranging from 6;11 to 10;1 years) and gender. Subtests of the Comprehensive Assessment of Spoken Language (E. Carrow-Woolfolk, 1999) were used to evaluate language ability. The Teacher Behavior Rating Scale (C. H. Hart & C. C. Robinson, 1996) was used to evaluate reticence. The current study replicated previous research by documenting significantly higher levels of reticence in children with LI when compared to typical peers. Significant group differences were also found in paragraph comprehension, syntax …
