(more)
▼ It is a well recognized fact that pavements with poor subsurface drainage properties prematurely exhibit distress and have higher life-cycle cost. Thus, providing adequate subsurface drainage in a pavement system to remove the infiltrated moisture in a timely manner is an important design consideration. Currently, Ohio Department of Transportation (ODOT) accepts several types of materials specifications for use as drainable base materials. They are ODOT 307 (NJ, IA, and CE), ODOT 308 (asphalt treated), and ODOT 306 (cement treated). However, the effectiveness of these base materials in actual service has not been conclusively established in previous ODOT studies. Consequently, a research project, so-called ATB-90, was initiated in 2002 to provide additional data to assess the merits of the drainable bases in the asphalt pavement.

(more)
▼ The tympanic membrane and external auditory canal serve auditory and non-auditory functions. Both the luminal surface of the external auditory canal and the lateral surface of the tympanic membrane are composed of a stratified squamous, keratinizing epithelium. Epithelial migration is a process that serves as a self-cleaning and repair mechanism for the external auditory canal and tympanic membrane. Epithelial migration has been evaluated in humans and several other species, but not in dogs. The majority of these studies employ an ink drop method in which discrete markers of ink are placed on the lateral surface of the tympanic membrane and the pattern and rate of these markers are monitored over time. Failure or abnormal epithelial migration has been implicated as a potential cause of some otic diseases in humans and has been assessed in otitis externa, keratosis obturans, external auditory canal cholesteatomas, retraction pockets, and middle ear cholesteatomas. The objectives of this study were to determine the rate and pattern of epithelial migration on the tympanic in clinically normal laboratory dogs and to describe a technique for ink drop placement on the canine tympanic membrane to be used for future studies. Eighteen dogs were anesthetized, and three drops of waterproof drawing ink were placed on two sites of the pars tensa and one on the pars flaccida. Images were recorded with a video otoscope and digital capture system. Each dog was evaluated and images recorded every six to eight days for four evaluations. Migration pattern analysis and epithelial migration rate calculation were performed with image processing software. Descriptive statistics for epithelial migration rate (mean, standard deviation, 95% confidence interval) were calculated for all ink drop locations on the tympanic membrane (pars tensa 1 [PT1], pars tensa 2 [PT2], and pars flaccida [PF]) at each time point. Eight fox hounds had digital images from both ears that met the criteria for image analysis, while all beagles and two fox hounds only had images from one ear that met the criteria for image analysis. No significant differences in the mean epithelial migration rates were identified between right and left ears of the eight fox hound dogs, between breeds (beagle, fox hound), or between locations PT1 and PT2. The mean overall epithelial migration rates (±standard deviation) were 96.4 (±43.1) and 225.4 (±128.1) micrometers per day for the pars tensa and pars flaccida, respectively. All ink drops moved outwards, the majority (48 of 53) in a radial direction, from the original location to the periphery of the tympanic membrane. Migration of the ink drops off the tympanic membrane was observed during the study period for all three locations. The ink drop placement method used in this study can be used in future studies to determine the epithelial migration rate of the canine tympanic membrane. Future investigations of epithelial migration should focus on dogs of different ages, dogs predisposed to otic diseases, as well as dogs with existing otic conditions.

▼ Verb aspect is a subtle feature of language usage and comprehension that denotes a certain time frame within which an event occurs. Sensitivity to verb aspect may play a role in adult’s linguistic understanding by marking particular features of an event as salient. This study investigates whether verb aspect modulates both adults’ and children’s access to one particular event feature, the location at which the event occurs. English distinguishes between two aspects, the imperfective and the perfective. The imperfective aspect conveys that an event is ongoing, while perfective aspect conveys that an event is completed. Research with adults using semantic priming methods has shown that only verbs marked by imperfective aspect facilitate naming latencies for locations at which the events referred to by the verb typically occur. Verbs marked by perfective aspect do not result in such facilitation. This study extends previous research by replicating priming in adults for imperfective verb-location pairs using a modified, partly novel, stimuli set. By contrast, children aged 11-12 showed priming for locations following both imperfective and perfective verbs when tested with the same modified stimuli set.

Weight Based Stigma: The Impact of Perceived Controllability of Weight on Social Support.

(more)
▼ Although current society values equality, weight-related prejudice is prevalent and still seen as acceptable (Puhl and Brownell, 2006). One resource that could help negate the deleterious effects of stigma may be social support, a resource that suggests one is cared about and valued (Rodriguez and Cohen, 1998). Social support may benefit in two ways- it can buffer or moderate the relationship between stigma and health, and it may mediate the relationship between stigma and health. Both roles of social support will be examined in this dissertation. To my knowledge, only one study has examined the possibility that social support may act as a buffer in the weight-based stigma health relationship. Xie and colleagues (2005) found in their sample of Chinese youth that social support moderated the relationship between weight-based stigma and depressive symptoms. As for social support’s role as a mediator, although research suggests social support can function as a mediator (Kaniasty and Norris, 1993), this is the first study to examine this issue within the context of weight-based stigma and health, and analyses will be somewhat exploratory. While both functions of support may be beneficial, it is often reported that overweight and obese individuals do not receive adequate social support (Ali and Lindstrom, 2005). A large reason for these support deficits may be friends’/families’ perceptions of the controllability of weight. Research has shown thatindividuals that believe a person is responsible for their stigmatizing condition show less sympathy and less support may be provided (Seacat, Hirschman and Mickelson, 2007). To my knowledge, this dissertation is the first to examine this theory with friends and families perceptions of weight controllability. Integrating several literatures, I made several hypotheses. First, I hypothesized that perceived stigma would have a deleterious effect on mental and physical health. Second, I hypothesized that social support would buffer the relationship between stigma and mental/physical health. Finally, I hypothesized that perceived controllability of weight would impact perceived social support. 165 women enrolled in undergrad psychology courses completed the questionnaires. Results indicated that perceived stigma did not predict eating behaviors, exercise behaviors or depressive symptomatology. However, upon further investigation, I found that self-esteem (which was used as a control variable) may have been mediating the relationship between stigma and mental health. Results also indicated that emotional support from friends (but no other support) acted as a buffer in the relationship between stigma and depressive symptomatology (but no other outcomes). In regards to mediation, results indicated a marginal meditating effect of instrumental support from friends (but not family) in the relationship between perceived stigma and exercise (but not eating behaviors). Finally, contrary to hypotheses, family’s perceived controllability of weight was positively related to emotional and instrumental support from family, and friend’s perceived controllability of weight was positively related to instrumental support from friends. Results highlight family and friends’ role in the stigmatized individual’s life, and indicate that support from friends may be more salient for college-aged individuals than support from families. Further, results suggest that individuals perceive more support when they believe their family and friends perceive weight as controllable, suggesting that previous research regarding strangers may not extend to family/friends. Future research should examine the impact of controllability of weight from the perspective of the support providers.

(more)
▼ This research examines how women who experience a change to a partner of a different gender, use categories of gender, sexual identity, and sexual orientation to make sense of this shift both to themselves and to others. Specifically, the study draws on interviews conducted with self-identified lesbian, bisexual and queer women who have moved from relationships with female partners to relationships with male partners. Examining the stories people tell about their sexual selves provides not only an understanding of individuals’ sense of who they are, but also the ways in which a given culture organizes sexuality. In examining how women use and negotiate sexual identity categories, this research contributes to scholarship concerned with the ways in which sexual identity categories are shaped and become powerful forces in shaping people’s lives. Far from considering sexuality a dichotomous system of classification, with exclusive categories such as heterosexual and homosexual, recent scholarship has emphasized how individuals navigate sexual identity categories and engage in behavior that defy simple and dichotomous classification schemes. Despite this shift towards a more fluid understanding of identity, sexuality scholars have for the most part neglected to examine movement between or across sexual identity categories. This is so especially true regarding individuals who transition from marked to unmarked identity categories. After having lived most of their lives within a “marked” category (lesbian, queer, bisexual) the women interviewed for this study suddenly found themselves in an “unmarked” category (straight or heterosexual) once they entered into relationships with men. Far from experiencing this transition as a relief, as might be expected, the invisibility associated with being unmarked was neither expected nor welcome. In fact, it brought a sense of discomfort. Many tried to renegotiate a marked identity for themselves: one that was different from their previous lesbian identity. The stories of lesbians who begin relationships with men therefore inform us about how individuals navigate issues of belonging and the embodiment of desire, and how they connect identity and community. In short, their narratives of change to a partner of a different gender are a powerful way of “doing” their non-straight identities.

THE MEASUREMENT OF ENDOGENOUS mRNA EXPRESSION OF PLD ISOFORMS IN HL-60 CELLS USING QRT-PCR AND THE IMPACT OF THESE ISOFORMS ON GENE EXPRESSION OF mTOR AND S6K.

(more)
▼ Phospholipase D (PLD) is an enzyme that hydrolyzes the phosphodiester bond in phosphatidylcholine, yielding choline and phosphatidic acid (PA). There are two main isoforms: PLD1 and PLD2, which share 50 % genetic homology. Both PLD isoforms are highly regulated by fatty acids, small GTPase proteins, protein kinase C, Ca2+, and phosphorylation. PLDs are involved in physiological and cellular signaling pathways, primarily through the production of the lipid second messengers PA and diacylglycedrol (DAG). While PA is involved in a variety of intracellular mechanisms, the role of PLD, independent of PA, in regulation of signaling protein kinases is not fully understood. This is particularly the case for the protein kinases mammalian target of rapamycin (mTOR) and ribosomal p70S6K. mTOR is a kinase, activated by growth factors and inhibited by rapamycin, that contributes to cell growth and proliferation. p70S6K, also a kinase, is a substrate of mTOR and catalyzes the phosphorylation of the S6 protein, a component of the eukaryotic ribosomal 40S subunit. P70S6K also plays a role in the regulation of cell growth. The objectives of the present study were to analyze: (a) if the expression of the PLD mRNA isoforms were subjected to regulation by the expression of members in other cell signaling pathways, namely mTOR and S6K, and (b) if such regulation should exist, how it might be modulated by granulocyte agonists, specifically chemoattractant agents Epithelial-neutrophil activating peptide (ENA-78), N-formyl-methionyl-leucyl-phenylalanine (fMLP) and Interleukin-8 (IL-8). Using a variety of molecular methodologies, we were able to establish a working method for high-yield transfection of the human promyleocyitic leukemic (HL-60), a hematopoietic cell line that grows in cell culture in suspension. Real Time PCR (qRT-PCR) was optimized for the four genes of interest in this study: PLD1, PLD2, mTOR, S6K. Using qRT-PCR, we found that DMSO differentiated HL-60 cells (dHL-60) that express the neutrophilic phenotype, were able to respond to ENA-78, fMLP, and IL-8. Gene expression of PLD1, PLD2, mTOR and S6K increased in presence of ENA-78 and IL-8. On the other hand, fMLP increased gene expression of PLD2, mTOR and S6K, but not PLD1. Endogenous gene expression after silencing with specific, double strand, small interfering RNAs (si RNA) was also investigated. PLD1 RNA interference effectively silenced PLD1, but showed a small degree of non-specific silencing towards PLD2 as well. PLD2, mTOR and S6K were effectively silenced by RNA interference. Interestingly, the silencing of the latter genes was not rescued (brought back to basal levels) by fMLP or IL-8 induction. Further, a relationship between the PLD2 and the mTOR/S6K kinases was found, namely, that when either mTOR or S6K gene expression is silenced, PLD2 expression is dramatically potentiated. We propose that mTOR and S6K expression negatively regulate PLD2 gene expression, and this cannot be rescued by cell stimulation with chemoattractants. The mechanism by which RNA from a set of cell signaling molecules influence the expression of other genes is not addressed in this thesis, but several exploring possibilities are discussed.

(more)
▼ Cycling of mercury (Hg) and monomethylmercury (MMHg) in forest ecosystems can affect exposures of terrestrial and aquatic wildlife within the watershed. Litterfall has been posited to be a major source of MMHg and total Hg to the forest floor; however, the origin of MMHg associated with tree foliage is largely unknown. I tested the hypothesis that leaf MMHg would be controlled by root uptake and thereby proportional to levels in soil. Fresh leaves and associated soil samples were sampled from nine tree species (deciduous and coniferous) at 30 locations spanning a 1145 km2 area in southwest Ohio, a region presumed to have relatively homogeneous atmospheric deposition of Hg and MMHg. Concentrations of Hg species in tree leaves were unrelated to those in soil. In contrast, tree genera and trunk diameter were dominant variables influencing Hg levels in tree foliage. The fraction of total Hg as MMHg was relatively constant among all genera and averaged 0.4%. Results of this study suggest that uptake of gaseous Hg0 from the atmosphere is the dominant source of total Hg in foliage and that MMHg is formed by in vivo transformation of Hg(II) in proportion to the concentration accumulated. Via litterfall, it appears that processes associated with tree leaves are a major source of total Hg and MMHg to the forest floor.

(more)
▼ Since their immigration to the United States, Arab Americans have faced discrimination and stereotyping, especially through the mainstream media. After the events of September 11, 2001, these stereotypes progressed and reports of discrimination significantly increased. As reported by Ibish (2003), incidences of political injustice and ethnic hate crimes, after 9/11, have resulted in dire consequences for Arab American families, especially for their children in the public schools. Following the attacks, Arab American children and adolescents in the K-12 school system faced discrimination and violence from their classmates, teachers, and other school staff. The purpose of this study was to investigate multiple domains of self-concept in Arab American adolescents in relation to their school experiences, including discrimination, self-perceived teacher and classmate social support, and actual teacher-perceptions. Self-concept was measured by using the Self-Perception Profile for Adolescents (Harter, 1988). Results indicated that half of the sample experienced some form of discrimination, either personal or someone the subjects knew. Experiences of discrimination were significantly related to students’ Scholastic Competence and Physical Appearance. Self-perceived classmate support was significantly related to all domains of self-concept. Teacher related variables, however, deemed less significant, except for behavioral aspects of self-concept. Implications of these results are discussed as well as strategies for how to provide positive relationships with Arab American students and families will be outlined.

▼ A TWO-LEVEL HIERARCHICAL LINEAR MODEL ANALYSIS OF THE RELATIONSHIP BETWEEN SUSTAINED, TARGETED PROFESSIONAL DEVELOPMENT FOR TEACHERS AND STUDENT ACHIEVEMENT IN MATHEMATICS ABSTRACT ANNA MARIA TABERNIK The No Child Left Behind Act (NCLB) of 2001 put in place sweeping educational reforms targeted to raise school accountability for student achievement. Research has confirmed there is a distinct relationship between quality instruction and student learning, so one by-product of this reform movement is to provide every student with a high quality teacher, every year, in every classroom. This presents a challenge to school districts where teachers may not have the training and content knowledge necessary to raise the bar for students. Professional development has long been a routine service provided by school districts. In Ohio, however, with school funding dependent on property taxes determined by voter approval of school levies, budgets have gotten tighter. Therefore, districts are often forced to choose between funding professional development to improve student achievement and funding other basic programs. An analysis of variance and Level-2 hierarchical linear models were used to explore the relationship between teacher participation in targeted, sustained professional development in mathematics and student performance on the Ohio Achievement Test for Mathematics (OATM). Sixty-nine teachers were selected for this study from those who had participated in professional development through the SMART Consortium between June, 2004 and April, 2007. Over 4,100 OATM test histories were retrieved for students of the selected teachers. Results indicated there was a positive relationship between teacher participation in sustained, targeted professional development and student achievement on the OATM. Teacher participation in a minimum of 90 hours of professional development, years of experience, and certification in mathematics were all significant predictors of student performance on the 2007 OATM. Teacher participation in professional development and teacher certification in mathematics were associated with a narrowing of the gap between male and female students with regard to level of improvement in student performance on the OATM from 2006 to 2007. Finally, teacher background in mathematics was associated with a narrowing of the minority achievement gap with regard to level of improvement in scores over the two year period. Professional development, as shown in this study, can serve to enhance teacher characteristics, adding value to student learning and supporting increased student achievement.

(more)
▼ Degradation of the bone, mainly as a result of osteoporosis, causes loosening of the screw-bone interface. This problem exists, for example, in pedicle screws that are widely used for the treatment of certain spine-related illnesses. As a result of bone degradation, the pull-out strength of pedicle screws hazardously diminishes. The conventional remedies such as using bone cement add their own problematic issues. This thesis is about developing a pedicle screw that mitigates these unwanted effects. The design and development of the so-called SMArt™ pedicle screw was described which utilizes the shape memory and superelasticity properties of NiTi alloys to expand itself in case its surrounding bone goes through osteoporosis. The SMArt™ pedicle screw makes use of Niti wire-tube inserts wrapped around its body. The wire is inserted into the tube. The screw is implanted in the pedicle in a collapsed form. However, the tube extends the assembly while reaching to body temperature; therefore enhancing the purchase of the screw in the bone. Another feature of such a design is removability. The wire can be activated at a safe higher temperature to retract the assembly so that the screw can be easily removed. A finite element (FE) model was developed to predict and evaluate the performance of the NiTi elements. This general model was implemented in COMSOL Multiphysics®. It was shown that this model can predict the thermomechanical behavior of shape memory alloys. The model can capture superelasticity, shape memory effect, partial transformation, and tension-compression asymmetry in SMAs and was validated against experimental results taken from the literature. The FE model was consequently used to simulate the performance of shape memory NiTi inserts on the SMArt™ pedicle screw. The outcomes of the simulation suggest that the assembly can achieve the desired functionality of expansion and retraction. Consequently, a parametric analysis was conducted over the effect of different sizes of the wire and the tube. The geometry sizes for the first sample of this innovative pedicle screw were determined based on the results of this analysis.

▼ At the intersection of East and West lays a conflicted social disjuncture presented physically in the disparate sectors of Beirut, Lebanon, and revealed in the city’s divergent infrastructure. The crowded roadways saturated with pedestrians, taxicabs, minibuses, and other commuters literally and metaphorically block, rather than facilitate, physical and cultural advancement in the city. As an interconnected network of exchange, infrastructure can bypass cultural norms of independent neighborhoods and transgress social boundaries and memories to become an agent of trade beyond goods—a platform for circulating gathered crowds and their varying ideologies throughout the city. Ethnologist Marc Augé analyzes this phenomenon in his book, In the Metro as he discusses the intricacies of the Paris subway system. Specifically, this network of passages allows for a rediscovery of the city as a totality within a ‘neutral’ public space, as the term is described by sociologist Samir Khalaf and planner Oussama Kabbani. As such, beyond the touristic advantages, the divided domestic population of Beirut could benefit from the quotidian encounters and renewed perceptions afforded by mass public transit on an urban scale. The connecting hubs then become the local meeting points, the moments of interaction with the unknown, the thresholds between two lives. Through such a proposal, the discourse on public transportation and the impact of infrastructure on a city hopes to move beyond pure utility, and into sociocultural reconnection empowered by architecture.

▼ The importance of making Downtown Cincinnati a better place to work, live, visit, and connect to uptown and other neighborhoods is getting stronger with every passing day. With various high-scale projects like the replacement of I-71/75 Brent Spence Bridge, and I-471 Corridor changes in the near future, the need to improve the circulation patterns of downtown Cincinnati is gaining prominence. This is a very dynamic time for downtown Cincinnati and its transportation system. The Ohio-Kentucky-Indiana Regional Council of Governments (OKI) sponsored a study in 1999, the Central Area Loop Study, covering the freeway inner belt of the cities of Cincinnati, Newport, and Covington. With the ever changing needs and requirements of Cincinnati, a decade old study on Cincinnati downtown is mostly obsolete. The purpose of this thesis is to study the circulation patterns in downtown Cincinnati and come up with recommendations for a better street network, serving a multi-modal transportation network.

(more)
▼ Large scale bank privatizations over the last ten years have resulted in vast changes in the ownership structure of banking sectors throughout the world. This dissertation explores both the macro and micro level effects of these changes in bank ownership structure. The first essay explores how changes in bank ownership structure affect capital allocation efficiency within countries. I find that the decline in government ownership of banks by itself does not have any impact on capital allocation efficiency; rather, what matters is whether foreigners or large domestic shareholders acquire the stakes relinquished by the government. Increases in domestic blockholder ownership of banks adversely affect the allocation of capital through increased lending activity to less productive industries, while increased foreign presence improves capital allocation efficiency by directing credit to more productive sectors and to industries that rely more on external financing.In the second essay I explore how changes in bank ownership structure affect the performance of individual banks and the banking sector. The primary contribution of this essay is to examine the role of large domestic blockholders on bank performance. I find that increases in large domestic blockholder ownership of banks are associated with poor subsequent performance in terms of asset quality, profitability, and bank value. In contrast, increases in foreign ownership lead to improvements in profitability and bank value, consistent with prior findings. Government ownership of banks continues to affect bank performance adversely. Finally, increased presence of large domestic blockholders in the banking sector has a positive spillover effect on banking sector asset quality and profitability, while increased foreign presence is no longer associated with improvements in the competitiveness of the banking sector, contrary to what prior studies have found.

▼ Following the September 11, 2001 attack on the United States, there has been increased utilization of the Reserve Components (RC) by the military to fight the wars in Iraq and Afghanistan. Service members in the National Guard and Reserve (NG/R) represent approximately 40% of the forces involved in these conflicts. Current research indicates that NG/R personnel and their families may be at greater risk to deployment stressors than their Active Component counterparts. Estimates for the development of mental health problems including PTSD among returning RC personnel, range as high as 42%. The focus of this study was to advance the identification of factors that minimize the negative effects of experience in a combat environment, and promote healthy reintegration of military personnel back into society. This research examined self-efficacy, social support, and spirituality with regard to their effects on service members' symptoms of PTSD and levels of resilience subsequent to deployment. Self-report questionnaire data were collected from 223 California Army National Guard soldiers between six to eighteen months following their return from Iraq or Afghanistan. Consistent with previous research, findings showed that the level of combat exposure was the most salient factor predictive of PTSD. Self-efficacy had a small positive effect on PTSD, yet social support and spirituality were not significant. When examining the determinants for resilience, higher levels of self-efficacy, social support, and spirituality were associated with higher levels of resilience, although combat exposure retained a negative influence. Significant differences were found between soldiers who were still under a service commitment with eight years or fewer in the military, and those with more than eight years time in service. The results of this study are encouraging for developing programs designed to better prepare NG/R soldiers for deployment. Implications for future research and military training are discussed.

▼ This dissertation is composed of four studies conducted in two predominant bacterial pathogens; Campylobacter spp. and Yersinia enterocolitica in swine production systems. The main scope was molecular epidemiology and antimicrobial resistance. The first study was conducted to determine the prevalence and antimicrobial resistance profile of Campylobacter in two regions. A total of 838 fecal and 1173 carcass samples were examined. Campylobacter isolation was done following recommended protocol. The minimum inhibitory concentration was determined using agar dilution to a panel of six antimicrobials. The overall Campylobacter prevalence was 56.3%. We found Campylobacter prevalence of 58.9% and 53.7% among conventional and antimicrobial free farms respectively (p=0.24). There was no significant difference between region 1 (54.1%) and region 2 (58.2%) (p=0.92). Higher proportions of Campylobacter were resistant to tetracycline (64.5%) and erythromycin (47.9%). Resistance to chloramphenicol (4.4%), gentamicin (3.2%), nalidixic acid (23.5%) and ciprofloxacin (4.9%) were also detected. Thirty-seven out of 1257 Campylobacter coli (2.9%) were resistant to both erythromycin and ciprofloxacin, drugs of choice for human campylobacteriosis. High prevalence of Campylobacter coli and high proportion of resistance in both conventional and ABF systems, regardless of antimicrobial use status, was found. We also evaluated the contribution of point mutations in the quinolone resistance determining region (QRDR) of the gyrA gene to quinolone resistance. A total of eighty Campylobacter isolates were selected based on minimum inhibitory concentration (MIC) of ciprofloxacin and nalidixic acid. Of the 21 ciprofloxacin and nalidixic acid resistant C. coli isolates, only six showed point mutations that resulted in Thr-86 to Ile (ACT to ATT) amino acid substitutions. These isolates had MICs > 4 μg/ml for ciprofloxacin and ≥ 128 μg/ml for nalidixic acid. No detectable gyrA mutation was detected among C. coli isolates with MIC ≤ 4 μg/ml to ciprofloxacin. The genotypic diversity of 99 C. coli isolates from different geographic regions, production systems and with different resistance patterns was also investigated by multilocus sequence typing method. A total of 50 different sequence types (ST), among which seven new ones, were identified. All STs belonged to ST-828 clonal complex with ST-828 putative founder ST. The most common ST was ST-854 (n=10) followed by ST-828 (n=5), ST-1096 (n=5) and ST-1100 (n=5). The C. coli population showed weak clonal structure with an IA of 0.46. Swine are recognized as a major reservoir and potential source of pathogenic Yersinia enterocolitica strains to humans. A total of 172 Y. enterocolitica were investigated to determine their pathogenic significance to humans. Phenotypic and genotypic diversity of the isolates were assessed using antibiogram, serogrouping and amplified fragment length polymorphism. Carriage of chromosomal and plasmid-borne virulence genes were investigated using PCR. More than two-thirds of Y. enterocolitica were pan-susceptible. The most predominant serotype was O:3 (43%). Twenty-two of 172 (12.8%) isolates were found to carry Yersinia adhesion A (yadA). Ail, ystA and ystB gene were detected in 36%, 77% and 26.2% of the strains, respectively. AFLP genotyping of isolates showed wide diversity and were grouped into nine clades.

▼ The genus Fusicornia Risbec(Hymenoptera: Platygastroidea, Platygastridae)is a widespread group in the Old World, distributed from West Africa to Vanuatu. All scelionids are egg parasitoids of arthropods, but the host of Fusicornia is not yet known. The species concepts are revised and a key to world species is presented. The genus comprises 19 species of which 14 are new to science.This work is part of the Platygastroidea Planetary Biodiversity Inventory, and the collaborative taxonomic methods developed for this international project are outlined.

▼ Wasps, Ants, Bees, and Sawflies one of the most familiar and important insects, are scientifically categorized in the order Hymenoptera. Parasitoid Hymenoptera display some of the most advanced biology of the order. Platygastroidea, one of the significant groups of parasitoid wasps, attacks host eggs more than 7 insect orders. Despite its success and importance, an understanding of this group is still unclear. I present here the world systematic revisions of two genera in Platygastroidea: Platyscelio Kieffer and Oxyteleia Kieffer, as well as introduce the first comprehensive molecular study of the most important subfamily in platygastroids as biological control benefit, Telenominae. For the systematic study of two Old World genera, I address the taxonomic history of the genus, identification key to species, as well as review the existing concepts and propose descriptive new species. Four new species of Platyscelio are discovered from South Africa, Western Australia, Botswana and Zimbabwe. Four species are considered to be junior synonyms of P. pulchricornis. From nine valid species of Oxyteleia, the new species are discovered throughout Indo-Malayan and Australasian regions in total of twenty-seven species. The genus Merriwa Dodd, 1920 is considered to be a new synonym. To better understanding of the relationships of subfamily Telenominae, I reconstruct the phylogeny based on approximately 3.7 kb of DNA sequence from 4 molecular markers (18S, 28S, COI and EF1-α) expanding 80 terminals: 6 genera (11 species groups), 5 broad-ranged out group genera. Results are drawn from both parsimony and statistical analyses (Bayesian and Maximum likelihood), and from 6 character coding and partitioning schemes. The molecular evidence showed that the subfamily is not monophyletic: one clade, the Psix group of genera, forms a monophyletic group with species of the tribe Gryonini, subfamily Scelioninae. Monophyletic clades were recovered with strong support including (Psix+Paratelenomus) and Gryon; Telenominae, s.str. (without Gryon and Psix group of genera); Phanuromyia and Telenomus crassiclava species group; Telenomus laricis species group; and Telenomus longicornis species group. The genera Eumicrosoma and Platytelenomus are nested within Telenomus californicus species complex. Pentatomoidea (Hemiptera) is the plesiomorphic host. The species in the clade Phanuromyia + Telenomus crassiclava species group all shared the same host group, Auchenorrhyncha (Hemiptera: Fulgoridae and Flatidae). The monophyly of the major genera Telenomus and Trissolcus is not supported; the interrelationships of their component species are largely unresolved.

▼ This study investigates the amount, distribution, variation and fate of trace elements in FGD by-product. Dry FGD by-product including lime spray dryer (LSD) ash have possible uses in agricultural and construction applications. However, the variability in the chemical properties, especially levels of trace elements, of LSD ash is a concern due to the possible release to the environment. Little variability over different time periods (e.g., daily to yearly) and little variability between samples collected from different particle collection hoppers were observed. Trace elements including As, Se, and Hg in LSD ash and in the leachate did not surpass limits for land application (EPA 503 Rule) or RCRA. Further study of LSD ash samples was conducted to examine the distribution of trace elements in different fractions. The results show that the concentration of As was consistently greater in the calcium-enriched fraction, while the Hg concentration was significant in all fractions. Specific surface area was found to be a factor controlling the levels of mercury in LSD ash fractions. Results suggest that As and Hg are stable in LSD ash due to high pH and significant amounts of Ca. However, when LSD is disposed in a landfill, dissolution of Ca may lower the pH and calcium concentration in the leachate which may facilitate the release of As and Hg. The study of trace elements in LSD ash was used as a base-line for investigating trace elements in dry FGD by-product collected from the Ohio State Carbonation and Ash Reactivation (OSCAR) process. The OSCAR process is a pilot-plant of a new dry FGD system used on a slip stream of flue gas from the McCracken Power Plant. Results suggest that OSCAR sorbents are effective for capturing trace elements, and the OSCAR cyclone samples can be beneficially reused.

▼ In this work, we present the results of large scale computer simulations using different approaches ranging from the usual quench from the melt to the building blocks method. We also present structural models of binary chalcogenide glasses, GeSe4, GeSe9, GeSe1.5, GeSe2 and SiSe2, amorphous silica and models of Ge-Se glasses heavily doped with Ag ((GeSe3)0.90Ag0.10, (GeSe3)0.85Ag0.15) through ab initio molecular dynamics simulations. GeSe4 and GeSe9 models are in good agreement with all the structural properties, vibrational properties and electronic density of states. The defect sites causing localization of electronic eigenstates in the band gap region are characterized. A detailed analysis of the atomic structure of these glasses shows that the Ge-centered tetrahedra are the predominant coordination motifs in g-GeSe4 and that the structure of g-GeSe9 consists of Se-chain segments which are cross-linked by Ge(Se1/2)4 tetrahedra. Having reliable models of (GeSe3)0.90Ag0.10 and (GeSe3)0.85Ag0.15, we study the dynamics of the network of these glasses with an emphasis on the Ag ions. We highlight the existence of trapping centers and explicitly illustrate the trapping and release process from thermal MD simulation. We show that first principles simulation is a powerful tool to reveal the motion of ions in glass. The models appear to be in excellent agreement with an array of experiments and should be useful for subsequent studies of these interesting materials. For certain binary IV-VI glasses, especially silica, we show that decoration of bond-centered column VI atoms on tetrahedral amorphous networks leads with appropriate re-scaling and relaxation to highly realistic models of IV-VI binary glasses. The models obtained present some additional features such as a proper asymptotic behavior in S(Q) for large Q. The method is used to produce other models such as GeSe2 and SiSe2. We also show that the combination of a reverse Monte Carlo approach with approximate first-principles molecular dynamics is effective for a challenging material g-GeSe2.

ANTHRAX TOXIN: IMMUNITY AND RECEPTOR ACTIVITY.

(more)
▼ Bacillus anthracis is a high priority biothreat agent because of two virulence factors, an anti-phagocytic capsule and an exotoxin, consisting of protective antigen (PA), lethal factor (LF), and edema factor (EF). These virulence factors inhibit the host immune responses, allowing the bacilli to rapidly multiply and overwhelm the host. While the capsule is nonimmunogenic, the PA component of anthrax toxin has been shown to induce a protective antibody response and is the main component of human anthrax vaccines, including the United States' anthrax vaccine adsorbed (AVA). This dissertation aimed to further characterize anthrax toxin activity, examine human antibody responses to AVA vaccination, and investigate the influence of toxin receptor type on susceptibility to anthrax toxin. Initial studies characterized the activity of LF and EF using the mouse J774A.1 cell line and examined if human antibody-mediated neutralization of toxin could be more efficiently assessed using human cells. A variety of human and animal cells lines, and human primary cells were examined for susceptibility to anthrax toxin. J774A.1 cells were the only cells found to be susceptible to LF-induced lysis, but all cells tested were susceptible to EF-induced increases in cAMP. The activity of LF and EF antibodies was also assessed utilizing the LF- and EF-susceptible J774A.1 cells. The results revealed that LF and EF antibodies do not significantly contribute to anthrax toxin neutralization in humans, and that antibodies to PA are sufficient to neutralize toxin activity. Lastly, the influence of receptor type on susceptibility to anthrax toxin components using Chinese hamster ovary cells (CHO), CHO cells lacking functional toxin receptors (CHO-R1.1), and CHO-R1.1 cells expressing the human forms of two PA receptors, TEM8 (CHO-TEM8) or CMG2 (CHO-CMG2) was examined. Unexpectedly, PA alone, previously believed to only mediate entry of LF or EF, was found to be toxic to CHO-TEM8 cells. CHO-TEM8 cells treated with PA alone displayed reduced cell growth and decreased metabolic activity. PA induced immediate cell swelling, and the cells became permeable to membrane-excluded dye, suggesting that PA-TEM8 binding leads to pore-formation on the cell surface. These unanticipated results reveal that PA alone might mediate toxic activity in disease.

▼ From a uses and gratifications perspective, this research project investigated the effects of love styles on motives for using the Internet to create new romantic relationships as well as on perceptions of online romantic relationships. Information about participants’ demographics, Internet use, and background experiences with romantic relationships was also collected in an effort to further characterize members of the sample. Results indicated that participants believed that adult romantic relationships created via the Internet are better able and equipped to fulfill individual, personal motives based on sex rather than motives based on love. While this study offered a first attempt at answering questions about the interconnectedness of love styles, motives, and perceptions, these findings unearthed a more complex mystery that needs further investigation. Future research in this line of inquiry has the power to make a positive impact on understanding of specific Internet usage, online dating services/functions, and most importantly, on the real people who use or may consider using the Internet in the search for romantic relationships.

▼ BACKGROUND: Contact lens induced papillary conjunctivitis (CLPC) was first reported in 1974. With the increased use of silicone hydrogel lenses for extended wear there has been an increase in inflammatory reactions in the eye, including CLPC. The changes that occur in the eye when using an extended wear lens might include: tear stagnation, localized pressure, and a closed eye environment producing an inflammatory condition caused by the frictional rubbing of the lens on the upper palpebral conjunctiva. METHODS: The Longitudinal Analysis of Silicone Hydrogel Contact Lens (LASH) study conducted in Cleveland, Ohio in 2007-08 included 205 patients fitted with extended wear silicone hydrogel contact lenses and had a primary endpoint of Corneal Infiltrative Events within the year of follow-up following lens fitting. In the present study, patients were identified as experiencing Contact Lens Induced Papillary Conjunctivitis (CLPC) in two ways, either through clinical diagnosis during the LASH study or through a retrospectively applied algorithm to capture substantial changes reported in the eye consistent with CLPC. We investigated the association of [i] the level of bacterial bioburden, [ii] the difference between the base curve of the lens and the curvature of the eye, [iii] the presence of prior adverse events, and [iv] demographic information with the development of CLPC, in a series of logistic regressions. We also modeled the relative hazard of developing CLPC for patients with “abnormal” vs. normal bioburden, after accounting for other factors. In secondary analyses, we compared the impact of bioburden within Gram + or Gram – classifications, and briefly assessed seasonality of CLPC diagnoses to assess the relationship to Northeast Ohio’s allergy season. RESULTS: Across the follow-up period for the LASH study, 19 patients were diagnosed with CLPC clinically and a total of 52 were diagnosed via the expanded approach - either clinically or via the algorithm. In separate analyses of these “clinically diagnosed” and “expanded” classifications, development of CLPC was not significantly associated either with the presence of bacterial bioburden or with the difference between the base curve of the lens and the curvature of the eye. In logistic regression modeling, we observed nearly significant effects of gender and race on the development of CLPC. Specifically, females displayed an odds ratio of 0.38 [95% CI: 0.14, 1.03] for developing CLPC as compared to males. Asians showed an odds ratio of 3.49 [95% CI: 0.94, 12.49] for developing CLPC as compared to Caucasians. In time-to-event analyses, our Cox Proportional Hazard models indicated significant gender and race differences, specifically, female gender was associated with a relative hazard of 0.32 (95% CI: 0.12, 0.86) for developing CLPC while both Asian (relative hazard: 6.3, 95% CI: 1.76, 22.57) and African- American (5.83, 95% CI: 1.64, 20.67) patients showed increased hazard for CLPC than did Caucasian patients. CONCLUSIONS: Hygiene, environmental factors, and physical characteristics may potentially describe the outcome of developing CLPC, although the only significant associations we could find in this small study were linked to gender and ethnicity. Our data are not inconsistent with the hypothesis that seasonality plays a role in the development of CLPC, but a larger sample size would be required to confirm this finding.

▼ This qualitative case study examines the help seeking behaviors of 28 undergraduate students. This research identifies: the type of help they seek, from whom they seek help, and when they seek help. This research also investigates: the relationship between self-esteem and help seeking in an online environment and the use of self-regulated learning strategies in an online learning environment. This research utilizes grounded theory as its theoretical framework. To investigate help seeking in an online environment, this study employed questionnaires, standardized tests, weekly journals, interviews, and focus groups. In terms of type of help sought, students in an online course seek executive help rather than instrumental help. It was also discovered that the majority of the students get frustrated with their inability to solve problems without help and assume that an online class is easier and less time-consuming. When examining from whom students seek help, the majority of the students appear to seek informal help from their friends, but formal help from their instructor. In terms of when students seek help, the findings suggest they seek help almost immediately. In investigating the relationship between self-esteem and help seeking in an online environment, the findings reveal that the majority of the students are correct in their self-analysis of their level of self-esteem. It was also discovered that the majority of the students, regardless of their level of self-esteem, are open to seeking help. This inquiry also reveals that students consider self-esteem a multidimensional construct (i.e., academic self-esteem versus social self-esteem). When examining the use of self-regulated learning strategies in an online learning environment, the findings reveal that only half the students use higher level learning strategies. In addition, this research suggests that the majority of the students use the same learning strategies in the online learning environment as in a face-to-face environment. In conclusion, future researchers need to: include collaborative activities in online learning to promote instrumental help seeking, take into account the fact that self-esteem is multidimensional, design activities that will lead to deep learning, and inform students of the role adjustments that the online students have to make.

▼ The imagery of paper money embodies the hopes, history and the propaganda of a nation. Such images are the clothing with which nations dress their insecurities. They are the business cards nations put forward for introduction. Digitally transferred imagery from the back of a $2 U.S bill placed puzzle like fashion on to fifty white cot¬ton tee-shirts and a huge 125"X100" images of Bolivian Guerrilla leader Azurduy de Padilla taken from the nation's 1000 peso note, are just two highlights from this exhibit entitled "Nationalist Portraits". The exhibit uses ten images from paper currency of varying nations and mag-nifies them in order to suggest a slightly hidden theme. The thesis for this exhibition describes, in first person format various life experiences of the artist that have allowed him to see the imagery of money. In this unique way, each piece is given a physi¬cal description as well as a bit of insight as to its deeper meaning. The artwork from "Nationalistic Portraits" is a step beyond the purely aesthetic; it is a unique view on a global human story as well as a whispered call for change.
