• Landscape scale and contaminant effects on aquatic assemblage structure.

      Morris, Charles C (2012-05-18)
      Biological surveys are routinely used throughout the United States to identify localized impairments in aquatic ecosystems. This approach however, has had limited acceptance for in situ assessment situations in determining specific sources or causes of observed impairments as required under Section 303(d) of the Clean Water Act. While the best approach for determining the effect of urban impacts on streams is to directly compare biological data before and after urban impacts this approach is rarely used because of the lack of historical or pre-disturbance data. Traditionally, the source-cause investigation focused on using aquatic life chemical criteria as benchmarks, resulting in a "violation perspective" methodology that emphasizes specific water quality criteria being exceeded. Relying solely on this approach can be problematic since not all environmental stressors will have established criteria (e.g., sediment criteria are lacking) and those having criteria may not be sufficiently protective of portions of the aquatic resource (e.g., ammonia). This violation perspective assumes that intermittent chemical sampling and analysis will eventually discover the variables (contaminants) causing the impairment and emphasizes a select few water quality criteria exemplifying the “pollutant” focused approach as opposed to a broader and more comprehensive pollution focused approach. Furthermore, chemical water quality criteria are further removed from the designated use, which is more directly measured by the biota and minimizes type I and II assessment errors that would otherwise be more frequent. Evaluating aquatic systems using the violation perspective becomes increasingly more problematic due to increasing water samples collection costs, increased analysis costs for possible chemical stressors, and determining the identity among the thousands of possible stressors. Imperative to this discussion is that slightly elevated contaminant concentrations, synergistic effects, or sporadic spikes could adversely affect fish assemblage structure. As a result, these factors can potentially result in a biological impairment without the occurrence of specific chemical criteria violations. Nationally, the perception of causality for biologically impaired systems has shifted from point-source influences to more diffuse non-point source influences. Difficulty in tracking these pervasive non point-source impacts, combined with the lack of pre-determined signatory relationships with biological assemblage patterns creates a more complex problem. One way of increasing our knowledge of signatory relationships is through multivariate analysis utilizing the definable relationships between aquatic assemblage structure and quantifiable environmental stressors. The purpose of this research was multifaceted. We investigated the relationship between stressor response models associated with an urban landscape, multiple assemblage response, and fish assemblage nutrient response. Essentially the study area for this research encompassed data collected from across the State of Indiana. The nature of the analysis performed resulted in this volume of data being compartmentalized into discreet spatially driven subsets that were analyzed independently. To determine the responsiveness of fish assemblages to stressors associated with an urban landscape we targeted the Salt Creek Watershed. Salt Creek is a Lake Michigan tributary in Northwest Indiana, USA, which drains a watershed experiencing rapid urbanization as part of the expansion of the Greater Chicago metropolitan area. The watershed supports a managed coldwater fishery comprised principally of the introduced Skamania strain of the steelhead (Oncorhynchus mykiss). The sustainability of this watershed depends on the proper management of warm water tributaries and salmonid water in the Salt Creek mainstem. Twenty-three fish species were collected in the Salt Creek watershed and were numerically dominated by creek chub (Semotilus atromaculatus) and green sunfish (Lepomis cyanellus) both of which are tolerant to a wide range of environmental conditions. Habitat quality, measured using the Qualitative Habitat Evaluation Index (QHEI), showed that the watershed was generally degraded and scores ranged from 12-69. Fourteen parameters were significantly correlated with reach scale ecological health and biological integrity. Factor analysis found three factors explained 69% of the contributed variance in the watershed fish assemblage. The first factor included habitat measures comprised of the QHEI score and three of its metrics (i.e., channel, riparian and instream cover scores) and explained 36 percent of data variability. The second factor was comprised of two contaminants (i.e., TDS and Chloride) and one local-scale land-use variable (Agriculture) that explained an additional 20 percent of the variability. The third factor was comprised of two local scale land-use variables (i.e., riparian zone and water) explaining 13percent of the variability. To evaluate the responsiveness of multiple aquatic assembles to watershed stress we target the Big Oaks National Wildlife Refuge. The Big Oaks National Wildlife Refuge encompasses the northern 51,000 acres of the former Jefferson Proving Ground (JPG) which was used from 1940-1995 as a munitions testing facility. Since 2000 the U.S. Fish and Wildlife Service has utilized the northern 51,000 acres of JPG for ecosystem-based management in conjunction with continued use by the U.S. Department of Army and Indiana Air National Guard for air-to-ground training. An investigation of factors that explained the variance in fish, crayfish, and macroinvertebrate assemblage structure and function was based on catchment and reach-scale land use, habitat, contaminants, and water quality. Habitat quality, measured using the Qualitative Habitat Evaluation Index (QHEI), showed that scores ranged from 25 to 85 (average 61.36 + 10.08). The substrate score, instream cover, riffle-run score, and channel score were the primary factors contributing to declining QHEI scores. Factor analysis found four factors explained 69 percent of the contributed variance in the fish assemblage, two factors accounted for 56 percent of the total variance in macroinvertebrate assemblages, and two factors explained 49 percent of the cumulative variance in crayfish assemblages. Overall drivers of assemblage structure were associated with broad scale issues of wastewater treatment, ground water, and land-use. Our results show that fish, macroinvertebrate, and crayfish assemblages respond to similar broad scale stimulus; however, the specific physical/chemical constituent responsible for the stress may vary, and the realized magnitude of the overall stress on the system may be expressed by each organismal group differently. Our data suggest that varying organismal groups can respond independently and stress reflected in one assemblage may not necessarily be observed in another.Finally, we evaluated nutrient response in fish assemblages targeting a large data set collected from the Indiana portion of the Corn Belt Plain Ecoregion. Due to the complex interactions between the various forms of Nitrogen and Phosphorus within respective cycles, Total Nitrogen (TN) and Total Phosphorus (TP) cycling interactions can no longer be accepted as sole limiting factors in either marine or freshwaters. This study is conducted as part of the U.S. Environmental Protection Agency (USEPA) desire to development regional nutrient thresholds. The first objective of this study is to develop a biotic model capable of determining the contributions of various nutrients, including Nitrogen components and TP, in streams using fish assemblages. The second objective is to establish an approach for designating defensible nutrient biotic index (NBI) score thresholds and corresponding nutrient concentrations, above which fish assemblages show alterations due to increasing nutrient concentrations. Sampling within Indiana’s portion of the Corn Belt and Northern Great Plain Nutrient Ecoregion occurred from 1996-2007 at 1274 sites. Nutrient data were reviewed for outliers and then sorted into three groups relative to drainage class. Each group was arranged into 15 ranges or “bins” using the Jenks optimization method in Arc GIS 9.3. Next, sites were assigned to each bin relative to observed concentrations. These bin assignments were used to populate the species occurrence model for nutrient optima calculation. Nutrient optima were calculated by dividing the sum of the weighted proportion of times a species occurred in each bin by the un-weighted proportion of times a species occurred in each bin. The derived nutrient optima were divided into eleven equal ranges, by nutrient, and tolerance scores (0-10) assigned with respect to each species derived optima. Nutrient tolerance scores were used to calculate Nutrient Biotic Index (NBI) scores for each sampling site by summing the number of individuals of a given species at the site and multiplying times that species tolerance value then dividing by the total number of individuals at the site. A single break point was observed for unionized ammonia, which showed an NBIUnionized Ammonia score shift between 0.003 and 0.03 (mg/L). The mean NBIUnionized Ammonia scores were 3.09 and 3.29, respectively. Nutrient Biotic IndexUnionized Ammonia scores were significantly correlated with IBI score and IBI integrity class. Three break points were observed for Nitrogen, Nitrate+Nitrite, demonstrating a significant NBINitrate+Nitrite score shift at mean concentrations of 0.13 mg/L, 1.09 mg/L, 3.15 mg/L and 6.87 mg/L respectively. The mean NBINitrate+Nitrite scores were 5.58, 5.37, 5.82 and 6.25, respectively. The observed relationship produced a convex curve suggesting an enrichment signature. Nutrient Biotic IndexNitrate+Nitrite scores were significantly correlated with IBI score and IBI integrity class. Two break points were observed for Total Kjeldahl Nitrogen (TKN), which were significant. The mean concentrations of TKN were 0.4 mg/L, 0.68 mg/L, and 1.27 mg/L, respectively. The mean NBITKN scores were 2.73, 3.10, and 3.37, respectively. Nutrient Biotic IndexTKN scores were significantly related to IBI score and IBI integrity class. Two break points observed for TN were significant at concentrations of 0.56 mg/L and 3.30 mg/L. The mean NBITN scores were 4.60 and 4.85, respectively. Nutrient Biotic IndexTN scores were not significantly related to IBI score or IBI integrity class. Two significant break points were observed for TP. The mean concentrations of TP were 0.07 mg/L and 0.32 mg/L, respectively and mean NBITP scores were 3.43 and 3.58, respectively. Nutrient Biotic IndexTP scores were significantly related to IBI score and IBI integrity class. Two break points were observed for Chlorophyll a (periphyton), which were significant. Mean concentrations were 10.15 mg/m2 and 134.14 mg/m2, respectively. Mean NBIPeriphyton scores were 3.75 and 4.20, respectively. Nutrient Biotic IndexPeriphyton scores were not significantly related to IBI score, but were significantly related to IBI integrity class. Four break points were observed for Chlorophyll a (phytoplankton), which occurred at Chlorophyll a (phytoplankton) concentrations of 2.33 μg/L, 10.98 μg/L and 49.13 μg/L, respectively. The mean NBIPhytoplankton scores were 3.43, 3.85 and 5.02, respectively. Nutrient Biotic IndexPhytoplankton scores were significantly related to IBI score and IBI integrity class. Nutrient criteria concentration was interpreted for NBI and IBI integrity class relationships to establish protective nutrient concentration benchmarks. Proposed mean protection values are 3.0 μg/L for Unionized Ammonia, 130 μg/L for Nitrogen, Nitrate+Nitrite, 40 μg/L for TKN, 70 μg/L for TP, and 2.33 μg/L for Chlorophyll a (phytoplankton). Criteria established at or below these benchmarks should protect for both biological integrity of fish assemblages in Indiana as well as nutrient loadings into the Gulf of Mexico.
    • Language Arts Achievement and Reading Instructional Strategies in Indiana Elementary Schools with High Percentages of Increasing and Declining Enrollments

      McMahon, Maryanne B.
      The focus of this quantitative study was to identify third grade ISTEP+ data from the top 10 increasing and declining enrollment public school districts in the state of Indiana to determine if communities experiencing high percentages of increasing or declining enrollments have significantly different achievement in language arts. This data was disaggregated to examine the subgroups of English Language Learners and Socio-economic Status. Additionally, the study determined if teachers in these schools were informed about scientific, research-based reading instructional strategies and to what degree SRBI was utilized in reading instruction to meet the needs of students. School corporations experiencing high percentages of student enrollment gains had a higher mean on the language arts portion of the ISTEP+ for third grade students, and the subgroups of free and reduced lunch, and English Language Learners. These findings have practical significance in demonstrating if third grade students attending increasing enrollment schools outperformed students attending declining enrollment schools academically in language arts. This data has implications for both state and federal legislation regarding school improvement categories. The second part of the study focused on teacher survey data to determine utilization and source of knowledge regarding scientific, research-based instruction in reading. As a result, teachers believe they were utilizing scientific, research-based instruction to meet the needs of their changing student populations; however, there is no evidence teachers learned SRBI in pre-service programs.
    • Language Learning Strategies of English as a Foreign Language University in Korea

      Yang, Mihwa (2010-07-20)
      The purpose of this research was twofold. The first was to investigate which English learning strategies are frequently used by EFL Korean university students, and the second was to discover the differences in the use of English learning strategies by self-assessed language proficiency and gender. This study investigated the strategy usage of 288 Korean university students through administering a demographic questionnaire and Oxford’s (1990) SILL. Independent t-tests, a one-way analysis of variance (ANOVA), a multivariate analysis of variance (MANOVA), post-hoc Scheffé tests, and chi-square tests were performed at the .05 level of significance to answer research questions. The findings indicated that Korean university students used a medium range of strategies. Compensation strategies were used most frequently whereas memory strategies were used least frequently among Korean university learners. Language proficiency levels had significant effects on the overall strategy use, the six categories of strategy, and individual strategy use items. The present study also found that gender did not affect the overall strategy usage of EFL Korean university learners, the six categories of strategy, and individual strategy use. In sum, this research provides English teachers and curriculum planners with validated information on strategies currently used by EFL Korean university learners. The findings allow English teachers and curriculum planners to understand which overall strategies are used by EFL Korean learners.

    • Learning styles of Myers-Briggs Type Indicators

      Cohen, Juanita Jane (2012-04-17)
      This research study illustrated that personlaity type influences learning type.The study compared the personalities expressed in Myers-Briggs Type Indicator(MBTI)to Felder and Silverman's(1998)Index of Learning Styles(ILS).Phase one was a combined MBTI and ILS assessment that was administered to 105 participants.To further define learning style,phase two was a follw-up questionnaire administered to 37 participants and was based on Goley's(1982)Learning Pattern(LP)assessment.The research did indicate a correlation between specific dichotomies of MBTI,ILS and LP.The Extravert and Introvert dichotomy in MTBI appeared to correlate with the Active and Reflective dichotomy in ILS.Furthermore,a relationship emerged for MBTI Sensing and the ILS Sensory dichotomy,although no connection appeared in MBTI and the ILS Intuitive dichotomies.Moreover,participants who preferred MBTI Sensing dichotomy generally preferred Sequential learning.Participants with Intuitive personality in MBTI appeared to be either Sequential or Global learners.Finally,it was interesting to note that 68% of the participants scored as Visual as opposed to Verbal learners.The findings indicated personality does affect leaning styles.Curriculum designers and corporate trainers should consider personality in their training.Although the number of participants was small,the findings were significant enough to indicate that further research could improve training effectiveness and should be conducted.

    • Levels of Selection in a Polymorphic Species

      Korody, Marisa L. (2013-09-05)
      Phenotype is affected by many factors, including but not limited to environment, conspecifics, and genetics. Evidence of phenotypic variation is everywhere, some of which is controlled solely by environment, and others that are fixed by genetics. Genetic polymorphisms are rare, but very useful for the study of selection and genetics. These genetic polymorphisms provide a phenotypic link to the underlying genetics and are even more useful when there are associated behavioral differences. I examine multiple levels of selection that are acting upon a polymorphic passerine, the white-throated sparrow (Zonotrichia albicollis). Males and females of this species occur in two morphs, white or tan, based upon the color of their crown strips. This plumage polymorphism is absolutely correlated with a complex chromosomal rearrangement on the second largest autosome. Within this dissertation I explore how climate needs to be addressed in ecological studies to fully understand the mechanisms behind variation. I explore whether sexual selection is acting within this species and the differences between the morphs through the use of Bateman Gradients. Darwin suggested that sex ratios influence sexual selection, but what about morph ratios? I examine the frequency variation of morphs within this species. Variation in morph production may be favored by a potential tradeoff between the number of males and the number of white offspring produced in a clutch that suggests greater costs associated with producing white morph individuals. Mendelian segregation is inconsistent in this species, and transmission distortion may contribute to morph ratio variation. I show that white male sperm varies in production from 0% - 100% white sperm/individual consistent with transmission distortion. Finally, candidate gene mapping was used to identify the genes sequestered in this rearrangement that may be responsible for the polymorphism and the evolution behind the rearrangement.
    • Life stress, adjustment, and religious support in African Americans.

      Maddux, Jemour A (2012-04-25)
      The paper sought to extend the work on religious coping in African Americans by exploring the religious moderators of the relationship between stress and adjustment between cultures. Specifically, the goal of the present investigation was to identify whether the buffering effects of religious moderators (i.e., religious coping and religious support) on the relationship between stress and adjustment varied by race. Many studies on African Americans supports that social and individualistic coping styles are respectively predictors of positive and negative adjustment. Results partially supported that religious support in African Americans was a better predictor of adjustment than religious coping. Overall, this was true for alcoholrelated variables, but not for well-being variables. Results provided much stronger support for the predicted moderating effect of religious support on the relationship between stress and adjustment in African Americans. Religious coping failed to moderate this relationship, and no significant buffering effects were found for religious coping or religious support in Whites. This is one of the study's strongest findings. Overall, results were consistent with Agnew's (1992) general strain theory. Alternative explanations for why hypothesis were, or were not supported are offered.
    • Male adolescents of divorce:the relationship with their noncustodial father.

      Kerr, Christine.L (2012-04-13)
      Since the divorce rate in the United States began to rise dramatically in the 1970's researchers have studied the impact of divorce on those involved.The research indicates that children whose parents divorce are more likely than children whose parents remain married to suffer from a lower level of well-being and are at greater risk for a myriad of researchers have focused on the impact of divorce on male adolescents specifically,studies of adolescent males in general indicate they are at risk for a variety of problems including poor school performance,accidents and involvement in crime. Recent research also indicates the importance of fathers in the lives of male adolescents.However,divorce frequently results in boys being placed in the custody of their mothers,which may disrupt their relationship with their noncustodial fathers.A modified Stevick-Colaizzi-Keen phenomenological method was used for interviewing and methods of analysis(Moustakes,1994).A qualitative investigation of the perceived experience of eight male adolescents of divorce and their relationships with their noncustodial fathers was conducted.The findings indicate that the experience of male adolescents(in this case all college students) regarding their relationships with their noncustodial father(a)impacts their perceptions of fathering.(b)creates a desire for a closer father-son relationship,(c)affects their definition of self,(d)results in a crossing of generational boundaries,(e)informs their lifetime meanings,(f)requires them to rely on others to meet their needs, and (g)confirms prior research findings that children are resilient and most do not carry debilitating psychological effects of divorce into adulthood.
    • Manipulation of Angiogenesis by Cyclosporine-A and Extracellular Matrix Molecules

      Pandey, Raghav (2012-10-19)
      Angiogenesis is the formation of new capillaries from pre-existing capillaries. Angiogenesis plays an important role in the blood vessel formation required during embryonic development, tissue injury, wound healing, and menstruation. It also plays a major role in tumor progression. We propose a mechanism that links the developmental pathways to a therapeutic pathway. Moreover, we show anti-angiogenic nature of an FDA approved immunosuppressant. Extra cellular matrix (ECM) has an important role in maintaining the shape and structure of organisms and in signaling mechanisms. Two major components of ECM are lumican and Magp2. Investigating their role might help us further link angiogenesis to tumor progression in cancer. We show the pro-angiogenic nature of Magp2 in an in-vivo model. Although this project is in early stages, it would provide a good foundation for future study. The aim of this thesis was to check the effect of blocking angiogenesis on tumor growth through different ECM proteins (Lumican and Magp2) and therapeutics (cyclosporine-A). Studying the progression of tumor links the chapters together.

    • Mentors’ perceptions of a university–school partnership through a student African American mentoring initiative

      Gilman, Amanda
      The participants in this study were 10 African American male college mentors at Indiana State University who participated in the Indiana State University Student African American Male Mentor Program, one school counselor, and two members of the Student African American Brotherhood administration. The study examined potential benefits to mentors, such as an enhanced feeling of connection and motivation, alleviation of feelings of alienation or isolation, counteracting of negative peer impact, and increased attachment to the university. All participants took part in semi-structured interviews and three mentors took part in a focus group. Grounded theory was used to analyze the data and create a description of the experiences and perceptions of the mentors. Several themes emerged from the data collected. The findings were that being a mentor held significant personal meaning for the mentors. Being a mentor did provide the mentors with a sense of belonging to the university. Mentoring also served to help the mentors stand out as role models and helped them create connections to campus leaders. Sharing experiences and making connections with those that were mentored was a valuable experience for the mentors. Black men’s issues, such as lacking role models, feeling stuck and feeling excluded, and acting White, were themes that were discussed extensively by the mentors. Overall, the participants in this study used their role as mentor to serve the younger generation of African American men they were mentoring. The young African American mentors in this study were not hindered by the stereotypes and negative expectations that have historically plagued them.
    • Middle School Special Education Reading Teachers’ Experiences Utilizing Study Island Technology to Enhance Male Students’ Literacy: An Exploratory Case Study

      Grimes, Roddran (2012-10-22)
      This mixed methods study examined the experiences that four middle school special education teachers had implementing an online education program called Study Island in their reading classes. The teachers wanted to increase their students’ reading decoding and comprehension skills and also wanted to prepare their students for their state’s standardized test. Many male students today are underachieving academically and lack motivation to excel in their studies. Because boys comprise the majority gender in most resource classes (i.e., only special education students), this study focused on the male population in order to determine whether an online education program with a game component such as Study Island would induce them to focus on content-specific reading passages and utilize their analytical skills to answer the associated multiple choice questions correctly. This study used interviews, observations, and analysis of Study Island reporting data in order to understand the experiences of the teachers and determine if the middle school boys were progressing in their literacy ability. The results of this study revealed that Study Island was effective if students were well-behaved and focused on the material, thereby enhancing the teachers’ perceptions of personal satisfaction. However, if students were distracted, unfocused, and unmotivated, less improvement was achieved and teachers felt sadness due to the lack of progress. This study also found that if teachers felt comfortable using technology, and received training and mentoring, they were more apt to use an online education program.

    • Moderating Effects of Religious Orientation on the Relationship Between Sexual Self-Discrepancies and Guilt and Anxiety

      Jones, Ann E. (2015-01-07)
      The current study examined the moderating effect of religious orientation on the relationship between sexual self-discrepancies and guilt. There is some evidence of a positive correlation between sex-guilt and higher levels of religiosity. In this study it was proposed that sex-guilt in religious individuals is partially driven by discrepancies between actual sexual behaviors and how the individual thinks that they ought or ideally should behave. In order to test this idea a survey was administered to 151 undergraduate students to assess religious orientation, actual, ought, and ideal sexual behaviors, and sex guilt. Gender differences were found in reporting intrinsic religiosity, sexual behavior, and sexual attitudes. Men reported more favorable attitudes toward sexual behavior, also, men reported more sexual behaviors than women, no significant difference was found between women and men in the intrinsic religiosity scores, and women reported higher levels of sex anxiety and sex guilt than men. Moderate negative correlations were found between intrinsic religious orientation and penile-vaginal sex for women; and mutual manual stimulation, and attitudes towards sexual permissiveness for men. Intrinsic religious orientation moderated the following relationships: ideal total sexual behavior discrepancy and sex anxiety for men and women combined; ideal manual stimulation discrepancy and sex guilt for men and women combined; ideal total sexual behavior discrepancy and sex guilt in men; and ought masturbation discrepancy and sex guilt in women. That is, those who reported higher levels of intrinsic religious orientation also report higher levels of anxiety and guilt, associated with discrepancies related to sexual behavior. This study contributes to the awareness of how religiosity can affect sex guilt. Based on the results of this study, the bogus pipeline methodology had limited utility when examining the relationships between intrinsic religiosity, sex anxiety, and sex guilt.
    • Moderating role of self-monitoring in the presentation of self through display of possessions.

      Burchard, Piotr.T (2012-04-12)
      The literature concerning the nature and presentation of the self is briefly reviewed, and the role of self-monitoring as a moderator in the presentation of self through display of possessions is discussed. It is hypothesized that high self-monitors differ from low self-monitors in the extent to which their private and public living spaces reveal their personality.Photographs of living rooms and bedrooms of 40 homeowners of different living status were collected to serve as stimuli and measure of the homeowner's personality and self-monitoring were taken.The photographs were presented to unacquainted observers who rated the homeowner's personality on the same scale.The correlations and discrepancy scores between the self-reported personality scores and observer's ratings were calculated for high and low self-monitoring homeowners for each living status category.The results, although partially consistent with findings of previous research,failed to provide clear support for the proposed and factors that could have influenced the obtained pattern of results are discussed.Lastly, limitations of the present study are acknowledged, and directions for further research are proposed.
