  • 1. Gallo, Melissa Vascular Access: A Navigation Map

    Doctor of Nursing Practice, Mount St. Joseph University , 2021, Department of Nursing

    Vascular access therapy is a term used to describe accessing the intravascular space of patients, to infuse blood products and other medications as well as remove blood samples for testing. Having reliable vascular access is crucial for the treatment of ill pediatric patients. Providers have many options available when deciding on the type of vascular access device (VAD) and placement location. Among the VAD options are non-tunneled central lines, tunneled central lines, ports, peripherally inserted central catheters (PICC), midline catheters, and peripheral intravenous catheters (PIV). This evidence-based practice quality-improvement (EBP-QI) project will focus specifically on the PICC placement through the use of a Care Algorithm for Vessel Selection to reduce unsuccessful insertions and increase vessel preservation in patients. Keywords: vascular access algorithm, vessel preservation, vascular access device complication, competency for nurses, assessment of nursing skills, nursing interventions, algorithm for central placement, lower extremity PICC placement, and femoral PICC placement.

  • 2. Hille, Kathryn Student Placement: A Multifaceted Methodological Toolkit

    Doctor of Philosophy (PhD), Ohio University, 2019, Educational Research and Evaluation (Education)

    Placement testing in intensive English programs (IEPs) involves methodological considerations that merit additional research. Neither quantitative nor qualitative methods alone have always proven successful to address common research problems in the field of IEP student placement, including questions regarding the selection of placement tests and the establishment of cut scores for those tests by means of standard-setting methods. These two key questions, alongside the methodology underlying them, comprise three necessary supporting elements for the achievement of appropriate student placement. This dissertation uses a three-article format to examine, in turn, each of these necessary supporting elements and its connections to the other two. The first manuscript, “The Application of Mixed Methods for Developing Student Placement Protocols in Intensive English Programs” serves as the methodological focus for this dissertation, exploring the potential of Mixed Methods Research to address the common challenges of inconsistent placement criteria and small sample sizes in IEP student placement and to yield recommendations regarding the selection of placement tests and the setting of cut scores. The second manuscript, “Placement Testing: One Test, Two Tests, Three Tests? How Many Tests are Sufficient?,” then provides a quantitative analysis to address the question of placement test selection so as to maximize placement accuracy and includes consideration of logistical issues as well. The final manuscript, “Setting Cut Scores for Student Success,” addresses the issue of establishing appropriate cut scores and presents an approach to synthesizing the potentially divergent cut score results that different standard-setting methods can yield. Taken together, these three manuscripts provide a close examination of multiple supporting elements that are necessary for the achievement of appropriate student placement; these manuscripts also challenge practitioners in the field (open full item for complete abstract)

  • 3. Bintz, Nicola The Transition from Cell Blocks to Street Blocks: An Examination of the Relationship Between Placement and Recidivism

    Master of Science in Criminal Justice (MSCJ), Bowling Green State University, 2013, Criminal Justice

    The literature on recidivism often discusses a strong link to returning ex-offenders' abilities to reenter their community or family unit in a successful manner with repeat criminal behaviors. Varied survey methods used in tracking recidivism rates have shown over time that recidivism rates have stayed relatively stable. This study analyzes data from a community-based correctional facility (CBCF) and state prisons. Post-release recidivism outcomes and their relationship to placement of individuals sentenced to a CBCF facility, prison and then a step-down program at a CBCF are examined. Overall, the findings support the idea that recidivism has not one significant factor but many. Type of placement was not related to post-release recidivism. Future research is essential to plans in effective recidivism reduction approaches and successful reentry programming by drawing attention to the needs of the individuals returning to our communities.

  • 4. Costiuc, Claudia Using Implicit Learning to Explain Brand Placement Effects

    PHD, Kent State University, 2009, College of Business and Entrepreneurship, Ambassador Crawford / Department of Marketing and Entrepreneurship

    Recent trends such as ad skipping have led to the adoption of alternative promotion strategies in reaching target audiences. Brand placement (BP), the inclusion of brands into entertainment with an attempt to persuade, is an increasingly common tactic used by marketers. Academic research has had a hard time keeping up with practice and has primarily focused on cognitive effects, viewing BP as another form of advertising. A few empirical studies have considered alternative theories for explaining BP effects in light of its unique entertainment setting. These studies show complementary nonconscious effects such as implicit memory and implicit attitude and find that explicit measures do not mediate effects on implicit measures, but lead to negative attitude effects. To date, however, no study has looked at how brand associations are learned from BP. To fill this gap, this dissertation adopted the implicit learning framework from cognitive psychology. Implicit learning suggests that even complex information can be learned 1) without awareness of what is learned, 2) without intention to learn, and 3) as a byproduct of some explicit learning. A total of 725 subjects were recruited to participate in three separate experiments conducted to investigate the effect of awareness on implicit learning and explicit learning in three different settings: across marketing communications, within BP, and across BP-advertising sequences. Measures assessed viewer learning of four of the nine brands embedded in the film I, Robot after viewing either the entire film or an edited clip. Learning was also used to explain conventional measures such as brand memory and brand attitude. Key findings show that 1) brand associations are learned differently in the BP and advertising contexts, 2) prominence may actually deter implicit learning within BP, and 3) there are interactive effects when BP and advertising are used together. Persuasion knowledge was found to be a useful covariate when looking (open full item for complete abstract)

  • 5. Schalk, Jaclyn The Academic and Co-Curricular Factors That Predict Full-Time Job Placement and Starting Salary Upon Graduation for College of Business Students

    Doctor of Education (Ed.D.), Bowling Green State University, 2013, Leadership Studies

    The purpose of this study was to examine the Academic and Co-Curricular factors that predict Full-Time Job Placement and Starting Salary upon graduation for college of business students. The sample consisted of 630 graduating college of business students at a mid-sized, four-year public institution in the Midwestern United States. Data were collected from 2009-2012 utilizing the College of Business Administration Senior Survey (CBASS), which was administered at each graduation ceremony in the years under study. Three research questions guided the analysis. The first research question examined which Academic and Co-Curricular factors predict Full-Time Job Placement upon graduation. Results of a logistic regression revealed a three-factor predictive model indicating that Degree of Internship Participation, G.P.A., and Area of Specialization were all significant predictors of Full-Time Job Placement. The second research question examined which Academic and Co-Curricular factors predicted Starting Salary. A one-factor predictive model resulted from a forward multiple regression, indicating that only Degree of Internship Participation predicted Starting Salary. Finally, the third research question examined if Internship Participation or Degree of Internship Participation predicted Job Attainment in Area of Specialization. Results of a logistic regression revealed that Degree of Internship Participation positively significantly predicted Job Attainment in Area of Specialization. Given the increasingly tenuous nature of the job market and an ever-changing global economy, the need to assist students in best positioning themselves for successful initial post-graduation employment is vital. The results of this study suggest that Academic and Co-Curricular factors, and in particular Degree of Internship Participation, Area of Specialization, and G.P.A., do have the ability to predict more positive employment outcomes for graduates.

  • 6. Chen, Shuhan Exploring the Catalysis and HDL-Association Mechanisms of Paraoxonase-1 and Optimization of Protein Sequence Using Consensus Analysis Approach

    Doctor of Philosophy, The Ohio State University, 2024, Chemistry

    Paraoxonase-1 (PON1) is an enzyme universally found in mammalian serum. It has been shown to hydrolyze a very broad range of substrates. The native substrates of this enzyme are likely to be lactones, while it also hydrolyzes aryl esters and organophosphates with lower efficiencies. PON1 also binds to high-density lipoproteins (HDL) in serum, which stabilizes the protein significantly and enhances its activities in vitro. It's also related to this enzyme's physiological function in mammalian serum. After being produced in liver cells, PON1 is transferred to HDL in serum and exerts anti-oxidative and anti-inflammatory functions. Loss of serum paraoxonase activities increases the risk of atherosclerosis development. Currently, due to the unstable nature of this protein, the structure information of native human PON1 is still not available. Several recombinant PON1 variants were created with higher stability and solubility. One variant along with several of its mutants (G2E6) was successfully crystalized and its structure was solved. Even though all current research is using G3C9 variant due to its better performance, a lot of information still can be exploited from G2E6 structures considering the high level of homology in their sequences. And thus, numerous mechanistic studies are performed based on this limited structural information. Based on all the available information, it is reasonable to believe that PON1 may adopt different mechanisms for different substrates. For lactonase and aryl esterase activities, key residues include the H115/H134 dyad, which have been hypothesized to serve as proton shuttlers and activate a water molecule for nucleophilic attack. This hypothesis is supported by a lot of mutagenesis and kinetics studies. But for paraoxonase activity, D269 is more likely to be the Lewis base that activates a water molecule for subsequent nucleophilic attack. Out of all the proposed mechanisms, the catalytic calcium ion is always seen as a Lewis acid t (open full item for complete abstract)

  • 7. Galeski, Janine NP student-perceived clinical placement and their intention to work: a program evaluation

    Doctor of Nursing Practice , Case Western Reserve University, 2024, School of Nursing

    Substantial funds are allocated to relieve the primary care shortage for urban and rural underserved populations. The Ohio Department of Health (ODH) provides funds for clinical rotations in federally qualified health centers (FQHCs), assuming this will lead to increased access to primary care. The CWRU MSN program actively participates in these placement programs and efforts. However, there is no scientific evidence that clinical exposure of NP students to underserved populations will lead to intent to practice. This program evaluation explored factors contributing to intent to practice with underserved populations in general and the role of clinical exposure in specific.

  • 8. Zeller, Brian Evaluating High School Principals' Perceptions of Barriers to Black Students' Enrollment in Advanced Placement (AP) Academic Coursework in Northeast Ohio

    Doctor of Education (Educational Leadership), Youngstown State University, 2024, Department of Teacher Education and Leadership Studies

    Black students in high schools do not matriculate in advanced level coursework, such as advanced placement (AP) classes, at the same rate as their White peers. The opportunity to participate in AP in high school has been shown to influence enrollment in college, earning higher overall grades, and better performance on high stakes assessments such as the ACT. A quantitative survey tool was administered to high school administrators from the Cleveland Area Minority Educators Recruitment Association (CAMERA) consortium, whose main objective was the recruitment and retention of minority educator candidates through networking opportunities, hiring, supporting minority educators, and promoting multicultural and multiracial relations. The study explored the relationships between the factors of poverty, caregiver education, teacher and school counselor expectations, Black teacher exposure, and peer influence and enrollment in advanced placement coursework. Additional influences were examined to determine if a correlation could be drawn between the demographic information of building administration and AP enrollment. The study showed certified staff and personal/familial factors as having the greatest influence on Black student AP enrollment. Leveraging current staff, recruiting, and retaining a more diverse staff, and removing any financial barriers for minority students were all possible solutions offered to improve AP enrollment. The outcomes of this study benefitted school principals, other school administrators, teachers, school counselors, and community members to mitigate the negative impact of these barriers. In turn, addressing these issues will help to shrink the current opportunity gap found between Black and White students in AP courses.

  • 9. Watson, Robert Implicit Bias In The Advanced Placement (AP) And Honors Selection Process: A Case Study Of A School District In The Midwest

    Doctor of Education, Ashland University, 2024, College of Education

    Ethnic minority students are underrepresented in advanced placement (AP) courses due to multiple factors. It is unknown the impact of teacher, counselor, and students have on limiting ethnic minority students from attempting AP classes. To investigate these unknown variables, three research questions aim to address this problem: What do teachers, counselors, and students believe to be the obstacles that limit minority students from taking AP courses. This qualitative case study investigated to get a better understanding of barriers for students to attempt the AP/honors classes. Data were collected through semi-structured interviews. The findings reveal that students, teachers, and counselors blame each other but not themselves as a contributing factor underrepresentation of ethnic minority students in AP/honors classes, and student peer-bullying has created a two-tiered tract that the culture of the school itself has actively maintained a climate and culture where students view others in an academic caste system where students are encouraged to stay in their perspective academic lanes.

  • 10. Turk, Rachel Magnifying the Stories and Voices of Recently Graduated African American Students in Advanced Placement Courses: Cultivating Equity and Participation in AP

    Doctor of Education, Miami University, 2023, Educational Leadership

    This qualitative study seeks to amplify the stories and voices of recently graduated African American students who completed at least one Advance Placement (AP) course to learn from their experiences and to understand how these students explain the underrepresentation of African American students in AP courses. Through semi-structured interviews with five recently graduated African American students from an affluent, predominantly White, suburban public-school district in Ohio, issues relating to how race played a role in their educational experience, specifically, in AP courses were explored. Approaching this study through the lens of critical race theory (CRT) allowed the voices and experiences of African American students to be central and to serve as reliable data upon which to assess and analyze their lived experiences. Five major common themes emerged from this study: the presence of bias and prejudice, self-negotiation of response, the paradox of isolation and illumination, the weight of racism, and lingering stereotypes and the will to defy them. The results of this study expand the conversation about the experience in AP courses via the voices of marginalized students as well as provide their insights as to why African American students continue to be underrepresented in AP courses. The study provides evidence that a different approach is needed to not only eliminate bias and prejudice in educational spaces for African American students who participate in AP but also increase equity and access for those considering participating in AP classes.

  • 11. Kang, Donghe Physical Layout Optimization in Scientific and Analytic Data Management Systems

    Doctor of Philosophy, The Ohio State University, 2023, Computer Science and Engineering

    The performance of scientific and analytic applications faces challenges as data volume and complexity have dramatically increased in past decades. Data management systems develop many techniques to optimize data storage layouts, thus speeding up the I/O procedure in these applications. Data partitioning and data placement are two representative techniques. Prior research splits a large object, such as a scientific array or a table, into many hyper-rectangular partitions. However, complex workloads expose non-rectangular access patterns that do not match with rectangular partitions. Furthermore, prior studies optimize the partitioning layout in a single data store. Modern systems often have diverse storage infrastructures, requiring a smart data placement strategy. Both data partitioning and placement decide the storage layout but prior studies consider them independently. This dissertation, therefore, matches the partitioning layout with the non-rectangular access pattern and jointly tunes data partitioning and data placement to maximize the I/O performance. As partitions of an object are placed and processed in a few data stores, a query on such an object is split into fragments executed separately. A significant challenge for the split execution is to reconstruct final answers efficiently. Stitching partitions incurs a massive amount of memory operations, especially for split SQL executions because relational operators return data in random orders. Sorting is one of the most expensive operators in RDBMSs. A slow reconstruction procedure easily offsets the benefit of optimized layouts. This dissertation makes four contributions to optimize the physical storage layout in scientific and analytic data management systems. The first contribution is a human-interpretable model to predict the end-to-end query evaluation time. The model is the foundation for comparing candidate layouts in optimization algorithms. The second contribution is an algorithm that jointly (open full item for complete abstract)

  • 12. Hiner, Steven Examining Statistical Differences Between Constructed Response and Computer-Scorable Questions on Accelerated Math Placement Assessments

    Doctor of Education (Ed.D.) in Organizational Leadership , Franklin University, 2023, International Institute for Innovative Instruction

    The purpose of this study was to determine if there were significant statistical differences between scores on constructed response and computer-scorable questions on an accelerated middle school math placement test in a large urban school district in Ohio, and to ensure that all students have an opportunity to take the test. Five questions on a placement test given in the spring of 2018 were changed into questions that could be graded by computer for students taking the test in the spring of 2021. The data was examined for each test first using whole group data. Significant statistical differences were found in each of the five questions, with four questions having a higher mean as a constructed response item and one having a higher mean as a computer-scorable item. No significant differences were found when scores were analyzed by gender, and only one question had statistical difference when analyzed by ethnicity. Correlation was calculated between each student's placement test score and their Math 8 state test score. Similar correlations were found between the two assessments during both testing years. To ensure that all students are provided an opportunity to succeed in an accelerated math pathway, all must need to be given access to helpful pre-testing materials and encouraged to take the placement test. Recommendations were made to continue using computer-scorable questions to provide an opportunity to identify as many qualified candidates for acceleration as possible.

  • 13. Pathirage, Chathuri Deshani Investigating the impact of host and viral factors on HIV-1 genomic RNA 5′ UTR structure and dynamics during reverse transcription initiation

    Doctor of Philosophy, The Ohio State University, 2023, Biochemistry Program, Ohio State

    Human immunodeficiency virus type-1 (HIV-1) infects CD4+ T cells, causing defects in the immune system leading to acquired immunodeficiency syndrome (AIDS). HIV-1 virus hijacks the transcriptional and translational machinery of the host cell to produce viral RNA and proteins. Full-length viral RNA is selectively packaged into virions, along with a number of host and viral factors that aid in successful viral infection of a target cell. The 5´ UTR, one of the most structurally and functionally dense regions of the viral RNA genome, is known to regulate many processes of the lifecycle, including RNA splicing, selective RNA packaging and dimerization, translation initiation and reverse transcription initiation. Interactions of the 5´ UTR with different host and cellular factors, as well as the RNA structure and conformational dynamics, are important to perform the aforementioned functions. In this work, we sought to characterize the conformational changes and interactions of the 5´ UTR that are involved in reverse transcription initiation. Human tRNALys,3 serves as the primer for HIV-1 reverse transcription. The 3′-18 nt of tRNALys,3 anneal to a complementary sequence called the primer binding site (PBS) in the 5´ UTR. HIV-1 reverse transcriptase (RT) binds to the primer-template complex and extends the 3′ OH group of tRNA. The initiation step of reverse transcription is slow and distributive, marked with several pausing events. In addition to the 3′ end of tRNA, several other regions of the primer are complementary to sequences within the 5´ UTR. Some of the additional interactions that have been identified in the HIV-1 MAL isolate 5´ UTR lead to conformational changes in viral RNA that facilitate reverse transcription initiation. Here we characterized the RNA conformational landscape of both tRNALys,3 and full-length HIV-1 NL4-3 5´ UTR upon forming the primer-template complex and upon RT binding, using selective 2′-hydroxyl acylation analyzed by primer extension (S (open full item for complete abstract)

    Doctor of Philosophy (PhD), Wright State University, 2022, Electrical Engineering

    Binary multipliers are ubiquitous in digital hardware. Digital multipliers along with the adders play a major role in computing, communicating, and controlling devices. Multipliers are used majorly in the areas of digital signal and image processing, central processing unit (CPU) of the computers, high-performance and parallel scientific computing, machine learning, physical layer design of the communication equipment, etc. The predominant presence and increasing demand for low-power, low-cost, and high-performance digital hardware led to this work of developing optimized multiplier designs. Two optimized designs are proposed in this work. One is an optimized 8 x 8 Booth multiplier architecture which is implemented using 32nm CMOS technology. Synthesis (pre-layout) and post-layout results show that the delay is reduced by 24.7% and 25.6% respectively, the area is reduced by 5.5% and 15% respectively, the power consumption is reduced by 21.5% and 26.6% respectively, and the area-delay-product is reduced by 28.8% and 36.8% respectively when compared to the performance results obtained for the state-of-the-art 8 x 8 Booth multiplier designed using 32nm CMOS technology with 1.05 V supply voltage at 500 MHz input frequency. Another is a novel radix-8 structure with 3-bit grouping to reduce the number of partial products along with the effective partial product reduction schemes for 8 x 8, 16 x 16, 32 x 32, and 64 x 64 signed multipliers. Comparing the performance results of the (synthesized, post-layout) designs of sizes 32 x 32, and 64 x 64 based on the simple novel radix-8 structure with the estimated performance measurements for the optimized Booth multiplier design presented in this work, reduction in delay by (2.64%, 0.47%) and (2.74%, 18.04%) respectively, and reduction in area-delay-product by (12.12%, -5.17%) and (17.82%, 12.91%) respectively can be observed. With the use of the higher radix structure, delay, area, and power consumption can be further reduced. (open full item for complete abstract)

    MA, Kent State University, 2022, College of Arts and Sciences / Department of History

    The goal of this thesis is to understand shifts in United States history curriculum over time by examining the Advanced Placement US History curriculum. Despite large changes in historical scholarship between 1958 and 2015, the American historical narrative represented in AP US History only changed gradually. This thesis uses yearly AP US History Course Guides from 1958 to 2015 and oral histories of committee members in charge of test development to illuminate the structural limitations that preserve the status quo in American history. The narrative presented through the Course Guides is evaluated through the metrics of type of history (political, social/cultural, economic, religious), gender, and race. The story of the narrative of United States history over these years is one of minor revisions in a field that needs major transformation. By improving our understanding of curriculum construction, not only will historical scholarship integrate more effectively into classrooms, but the American historical narrative will change from a focus on political players to a focus on all types of people who form and shape America.

    Master of Science (MS), Ohio University, 2022, Civil Engineering (Engineering and Technology)

    This research reviewed the current and future uses of Ultra-High Performance Concrete (UHPC) for bridge applications in the state of Ohio. Since most designers, owners and contractors are unfamiliar with the material and only a small percentage of all bridges utilize it, UHPC is still considered a relatively new material. Monitoring and understanding its performance in current applications will undoubtedly provide useful insights for future applications. Advantages of UHPC discussed include rapid strength gain that can be utilized in Accelerate Bridge Construction, fiber content which provides post cracking strength, high bond strength which shortens development lengths of reinforcement, and the flowable material which allows UHPC to better penetrate tighter spaces. Disadvantages of UHPC such as material cost, increased labor and time are also discussed. In addition, recommendations for future UHPC applications are provided that would benefit designers, owners and contractors through valuable insight that was gained during these research objectives. The first objective was to review the performance of UHPC in the Sollars Road adjacent prestressed concrete box beam bridge in Fayette County. The design of the UHPC longitudinal joint (shear keys) included dowel bars but eliminated intermediate diaphragms, transverse post-tensioning, and a composite deck. Comparing truck loading data from 2014 shortly after bridge construction was completed and 2017 during this study, the load distribution has improved to some extent and the bridge is responding to loading in a similar manner which implies minimal to no cracking of the UHPC shear keys. This simplified design may be a realistic alternative to solve the typical issue of cracking in the longitudinal joints (shear keys) and associated reflective cracking in composite decks for adjacent prestressed concrete box beam bridges. This improved behavior with UHPC joints may result i (open full item for complete abstract)
