Show moreOral squamous cell carcinoma (OSCC) is a significant contributor to the global cancer burden, with surgical resection being the primary course for treatment. However, achieving clear surgical margins remains a challenge owing to the complex anatomy of the head and neck, and it is estimated that as many as 30% of patients are sent home after surgery with residual cancer. Current surgical margin assessment techniques, such as post-operative histopathology and intraoperative frozen section analysis, either take too long to complete in an intraoperative time frame or have limitations in accuracy and efficiency. Fluorescence-guided surgery (FGS) has emerged as a promising approach to enhance intraoperative surgical margin assessment, with a few clinical research groups in the US and the Netherlands demonstrating the potential of epidermal growth factor receptor (EGFR)-targeted FGS in OSCC to identify at least a fraction of insufficient margins, intraoperatively. However, existing methods have demonstrated limited accuracy in detecting so-called “close” margins (cancer is found between 1-5 mm from the surgical margin), which are associated with an increased risk of local recurrence compared to “clear margins (>5 mm of healthy tissue at the surgical margin).This thesis evaluated the potential for a dual-aperture fluorescence ratio (dAFR) imaging approach to be used to improve the accuracy of close margin detection and localization in OSCC surgical margins. The dAFR technique involves dividing high numerical-aperture (NA) fluorescence images by low NA images taken from the same point-of-view, creating a ratio image that has been hypothesized to be correlated with depth of the fluorescence inclusion, in a manner that is insensitive to variability in tissue optical properties, in sub-diffuse photon propagation regimes. The validity of the hypothesis that dAFR signals can be correlated directly to depth of fluorescence in OSCC surgical margins was first explored in a set of Monte Carlo photon propagation simulations. The Monte Carlo simulation framework was also used to (1) guide the selection of the optimal range of numerical apertures (NAs) to use for the wide and narrow apertures for dAFR, (2) for evaluating the accuracy and precision of dAFR depth estimation across varying tissue optical properties, and (3) for evaluating dAFR depth estimation accuracy when tissue optical properties were heterogeneous, as would be expected in clinical OSCC margin imaging applications. A prototype dAFR-capable imaging system was designed based on the findings of the simulation work and was constructed considering factors such as accessibility, rapid imaging capability, safety, field-of-view, and image quality. The performance of the constructed system was then first evaluated through phantom experiments, where resinous materials with optical properties matching those of biological tissue and fluorescence at various depths were used to experimentally demonstrate the depth sensitivity of dAFR compared to single-aperture fluorescence (sAF) imaging. The dAFR system was then deployed to a clinic at the University Medical Center Groningen (UMCG) in The Netherlands to be tested out in a clinical pilot study. There, the surgical margins of 3 OSCC patients were imaged with our dAFR approach and the more conventional sAF approach and the correlations between dAFR and sAF measurement to histopathology measured margin thickness was evaluated at 12 different margin locations from 3 patients. In this pilot group of patients, dAFR provided significantly higher accuracy in detecting close margins compared to sAF (p < 0.02), with an area under the receiver operating characteristic curve (AUC of the ROC) of 1.0 for close margins. These results embody the first clinical demonstration of close margin detection in an intraoperative timeframe (< 2 min of imaging). Though the sample size was small (n = 3), these preliminary results have been used to leverage funding of the ongoing development of a second system prototype and the commencement of an 80-patient clinical study over the next 5 years. Other future research directions include the optimization of imaging hardware, correction for surface topography, expansion of clinical studies to other cancer types, integration with other imaging modalities, development of user-friendly interfaces, automated margin detection and localization of insufficient margins, and enhanced co-registration of margin localization in excised margins with in vivo anatomical structures to guide potential extended resection.

Show moreThis exploratory study investigates profiles of self-regulated learning (SRL) and expands on a gap in previous research. Previously found profiles were summarized, replicated, and differences among profiles in academic outcomes, personality, and goal orientation were examined. Additionally, these relationships were examined longitudinally to investigate whether personality or goal orientation predicted stability of profile membership. Four profiles were found using latent profile analysis in a participant pool of 270 undergraduate and graduate students: a very high SRL profile, a high SRL profile, an unmotivated but strategic SRL profile, and a low SRL profile. One-way ANOVA revealed grades did not differ significantly among profiles. Regression analysis found LGO, openness to experience, conscientiousness, and extraversion were significant predictors of SRL profile. Latent transition analysis was used for longitudinal analysis. Over time, participants were more likely to move from profiles utilizing more SRL to profiles of lower SRL. Generally, openness to experience, extraversion, agreeableness, and neuroticism predicted change more than stability, while PPGO predicted stability more than change

Show moreThe terms maintainability and maintenance are interrelated and often perceived to be difficult to distinguish from each other. Maintainability refers to the measures and actions taken during the design phase in order to assure that the building components and the system to which it belongs can be easily maintained at minimum downtime and cost. On the other hand, maintenance refers to the measures and action taken during the operation phase in order to keep the components at the desired operational condition. The variance between designers’ and facility managers’ priorities concerning maintainability creates a gap between the design and operation phases. Maintainability is not often considered in design nor is it a priority for designers. Designers consider equipment access to be one of the least important factors related to maintenance. However, design-related maintainability issues such as equipment access problems make maintenance activities impractical if not impossible in facility operation, and increase the life cycle costs of facilities. These issues can be detected in the design phase if an appropriate tool is available, and can prevent maintenance-related problems in the operation phase. This research aims to bridge the gap between design and facility management by developing and deploying a BIM tool that brings a facility management perspective into design, and allows designers to inject maintainability considerations into the design phase. In this study, the building and construction codes and standards adopted and published by the local governments of the United States were investigated in order to identify maintainability standards related to geometric design and parametric information of building components. Parametric rule sets related to maintainability were established according to the codes and standards. From the “equipment access” perspective, a maintainability checking algorithm that can be easily customized for any building component and its rule sets was developed. In order to demonstrate the operation of the algorithm in 3D design view, the algorithm was customized for a particular piece of equipment, codded in C# programing language, and implemented as an add-in called “Maintainability Checker” to the most commonly used BIM software: Revit. A video clip of the demonstration was embedded into a questionnaire, and the questionnaire was administrated to designers and facility managers in order to validate the potential benefits of “Maintainability Checker”. A comparative analysis of designers’ and facility managers’ opinions towards maintainability and “Maintainability Checker” was conducted using SPSS. The survey results indicate that the gap between the design and post-construction phases does exist. However, the survey results also indicate that “Maintainability Checker” can bridge the gap by allowing designers to produce a better design that improves equipment maintenance access and workplace safety, facilitates the cleaning and repair of building components, reduces the number of reworks, improves the efficiency of the commissioning process, and reduces the time spent on maintenance activities, all without increasing the workload of designers. The construction industry should consider an automated maintainability check to be an essential part of the design process, create/adopt design for maintainability standards for every building component that can possibly be in a structure, and use them within BIM tools.

Show moreThe aim of the present study was to investigate the “double-edged sword” nature of communication technology in its impact on the work-family interface. Communication technology has many wonderful advantages, one of which is the flexibility that it provides employees with where and when work is completed. The flipside, though, is that communication technology allows employees to be available and accessible at all times. The purpose of this study was to assess the impact of (1) accessibility and availability through communication technology; and (2) flexibility through communication technology, on the experience of work-to-family conflict, family-to-work conflict, and work-family balance. The study utilized Conservation of Resources theory and Job-Demand Control model as its basis for examining how the relationship between work and family demands and work-family interface outcomes are impacted by the two communication technology variables of interest in this study. Qualtrics Panels were used to recruit 405 working adults in the United States across various industries to complete an online survey. To help address single source bias, employees were asked to invite their spouse/partner to complete a survey to assess levels of work-family interface of the employee from the spouse/partner perspective. Hierarchical moderated regression analyses were used to test the hypotheses. The results indicated that employees who perceive that communication technology provided greater flexibility in the work and family domains experienced less work-to-family conflict, and family-to-work conflict, respectively. Further, employees who perceived that greater expectations to be available and accessible to others in their work and family domains experienced greater work-to-family conflict and family-to-work conflict, respectively. Accessibility and availability expectations exacerbated the association between demands and work-to-family conflict in both the work and family domains. Communication technology flexibility was found to buffer the effect of family overload in the experience of family-to-work conflict. The theoretical and practical implications of these findings and potential directions for future research are discussed.

Show moreIn this thesis, a new class of multiuser Non-Orthogonal Multiple Access (NOMA) is studied. Overall, the main contributions are listed as follows: Firstly, we study a new class of the space-time code (STC) based on a circulant matrix. A diagonal transmission matrix is adopted by utilizing the singular value decomposition (SVD) on the circulant matrix. After that, we present a Multiuser Multidimensional STC. This code expand the previous diagonal transmission matrix to multiple dimensions. Hence it produces a diversity due to the linear combination of all input elements. Two modified constellations are presented aiming at reducing the constellation expansion and the implementation burden. Secondly, a brief survey on state-of-the-art NOMA systems is provided, where their performance in terms of bit error rate (BER), overload capability and spectrum efficiency are compared. Thirdly, we study a NOMA system systematically. Firstly, an uplink NOMA system based on the Steiner Triple System (STS) is presented. A multiuser detection algorithm by using a reduced size vector correlator which will decrease the receiver complexity with an acceptable performance is proposed. Performance-oriented algorithm and overload-oriented algorithm aiming at handling different channel scenarios are studied. After that, we present a novel constellation forming methodology of downlink NOMA system aiming at solving the surjective-only mapping problem in NOMA systems. Compared with other methods by using constellation shaping, phase shifting and power scaling [1-4], our paradigm is capable of providing a new way to solve the surjective-only mapping with low design complexity. As far as we know, this method has not been used before. Finally, the impact of channel estimation error for NOMA system is simulated. The idea behind channel estimation is transmitting the pilot sequence and estimating the channel coefficient based on the received pilot sequence. As a future work, we will work on ARQ, cryptography and optimal designs.

Show moreJob embeddedness has been widely studied to understand why people stay at their organization, yet recently, research has started to examine the so-called “dark side” of job embeddedness. Drawing from Conservation of Resource (COR) theory, this study extends research on the potential “dark side” of job embeddedness, particularly examining its relationship between workplace incivility and turnover intentions, emotional exhaustion, and physical health symptoms. Contrary to the initial hypotheses, results from the study (N = 395) indicated that on-the-job embeddedness moderated (strengthened) the positive relationship between workplace incivility and turnover intentions. As expected, on-the-job embeddedness moderated (strengthened) the positive relationship between workplace incivility and emotional exhaustion, but it did not moderate the relationship with physical health symptoms. This study contributes to the workplace mistreatment and job embeddedness literature as it explored when and how on-the-job embeddedness and its components (i.e., links, fit, sacrifice), as well as off-the-job embeddedness influence the relationships between workplace incivility and work- and health-related outcomes. The discussion explores the broader implications of on-the-job embeddedness and workplace incivility, highlighting important considerations for both researchers and practitioners in managing employee retention and well-being.

Show moreGame-based assessments (GBAs) use games to evaluate knowledge, skills, abilities, and other characteristics (KSAOs). While research on their effectiveness is growing, little is known about how well game data can measure team-based constructs. This research is the first to systematically evaluate the validity of a team game-based assessment (TGBA) using a commercially available digital escape room. Guided by the Evidence-Centered Design (ECD) framework, relevant game metrics were identified, mapped to theoretical constructs of team processes, and tested against survey-based measures. Two studies were conducted to evaluate content, construct, and criterion validity. Study 1 used a Q-sort with expert judgments to establish content validity, confirming alignment between in-game behaviors and theoretical dimensions of team process such as transition, action and interpersonal team processes. Study 2 analyzed archival data from 26 teams' game logs, providing partial support for construct validity through significant correlations between game-based and survey-based measures of action and interpersonal team processes. Although the predictive power for team performance and team member satisfaction was limited, likely due to sample size, game design, and contextual factors, the results suggest that reverse-engineering existing games offers a feasible and cost-effective alternative to the time-consuming process of developing new games for assessment, particularly for low-risk scenarios. This research lays the foundation for future TGBA research and highlights the potential for future applications.

Show moreMany adults diagnosed with ADHD have often learned to cope with and adapt to the primary symptoms (i.e. impulsivity, inattention) of ADHD. However, adults with ADHD often cite the secondary symptoms (i.e. decreased self-esteem) that may accompany ADHD as significantly impairing their lives. Much of the research to date on treatment of ADHD has focused on ameliorating the primary symptoms of adult ADHD and less attention has been focused on the secondary symptoms of ADHD. Incorporating a mindfulness intervention into the treatment of ADHD could have wide-ranging benefits as mindfulness is a self-regulatory practice that can improve attention (primary symptom) and emotional regulation (secondary symptom). The goal of the present study was to evaluate the relationships among mindfulness and self-esteem, psychological flexibility, and functional impairment in an adult ADHD sample of 133 adults self-identified as having a diagnosis of ADHD. They completed the following measures: demographics questionnaire, Accepting without judgment subscale of the Kentucky Inventory of Mindfulness Skills (KIMS), Rosenberg Self-Esteem Scale (RSE), Work and Social Adjustment Scale (WSAS), Acceptance and Action Questionnaire (AAQ-2), and the Wender Utah Rating Scale (WURS). Moderated regression analyses were used to predict an outcome (i.e., psychological flexibility, functional impairment, or self-esteem) from two predictors (i.e., ADHD symptom severity, accepting without judgment) and the interaction between the two predictors. It was found that participants who were more mindful had greater self-esteem and reported less functional impairment.

Show moreThe current study examined leaders’ and subordinates’ conflict management strategies and how they relate to dyadic relationship quality. While a number of prior studies have investigated individual CMS styles and their association with outcomes of interest (including measures of relationship quality), this was the first study to measure and analyze full CMS profiles from both upward and downward perspectives. In high-quality LMX conditions, this study found a high degree of similarity between supervisors’ and subordinates’ full CMS profiles towards each other. Both supervisors and subordinates were higher on agreeable (i.e. integrating, obliging, and compromising) than disagreeable (i.e. dominating and avoiding) CMS. In low/moderate-quality LMX, supervisors and subordinates had dissimilar CMS profiles. The potential causes of differences between supervisor and subordinate CMS in low/moderate-quality LMX were explored. Contributions to the CMS research and practical implications were discussed.

Show moreHigher education institutions, particularly those who specialize in Science, Technology, Engineering, and Mathematics (STEM), are experiencing high turnover rates among their students. In work settings, mentors have been instrumental in the engagement and retention of employees. Therefore, we examined mentoring effectiveness and its utilization to help increase student retention and engagement for 118 students in a university in the Midwest. Also, we examined how perceived similarity between the protégé and mentor on surface- and deep-level characteristics (e.g., gender and gender role orienation) can influence both the perceived effectiveness of the mentoring relationship, as well as the protégé’s level of engagement. The results from this research found that surface-level variables, such as sociodemographic gender, were not related to the mentoring relationship or a student’s level of engagement. However, perceived similarity between the mentor and protégés on masculinity and femininity increased the protégés perceived effectiveness of the mentoring relationship. Further, perceived similarity and dissimilarity on protégé and mentor femininity increased levels of student engagement. Implications and avenues for future research are discussed.

Show moreContractors need financing throughout a project, mainly due to retainage, which is the money that the owner withholds to make sure that the project is performed properly by the contractor. Even if an owner does not withhold retainage, financing is still necessary because the periodic payments made by the owner are usually delayed. All pertinent studies conducted so far have considered only one source of financing without any consideration of different sources and types of financing, times of cash provisions, interest rates, and repayment options. Actually, if one assumes a predetermined credit limit and one source of financing, as past researchers have done, the optimal financing cost and the schedule that satisfies all constraints may be different than when several sources of financing and undetermined credit limit are considered. The main objective of this research is to focus on the optimization of financing cost by developing a financing optimization model based on different financing alternatives. Far lower financing cost and higher profit are obtained by using the proposed model compared to all models developed in past research. The research is conducted in four stages of development. In Stage 1, a financing optimization model is developed for a schedule that uses normal (not accelerated) activities, and early activity start and finish times. This model can be used before the contract is signed to offer the lower bid or can be used after the contract is signed to obtain higher profit. In Stage 2, the time-cost tradeoff algorithm is added to the model developed in Stage 1, considering accelerated activities between the crash and normal durations. In Stage 3, the model developed in Stage 2 is augmented by considering variable activity start times. Finally, in Stage 4, the model developed in Stage 3 is further improved by expanding time-cost tradeoff to allow for time extensions beyond the contract duration. All models developed in these four stages provide not only minimum financing cost, but also the ideal work schedule that achieves minimum total cost and maximum profit. Moreover, these models provide specific timings for borrowing and repaying funds.

Show moreA paradigm shift from single user to multiuser communications helps improve system capacity for an increasing amount of applications. Such systems such as cellular mobile radio and wireless local area networks are prone to multi-access interference. Although decoding techniques has been developed, the performance of such multi-access systems is severely degraded by increasing the number of users. Network coding increases the performance of such multi-access systems by increasing its diversity over independent or orthogonal channels at least equal to the number of users. A more resource efficient strategy ensures that the number of independent channels are less than the number of users This design also known as Non-Orthogonal Multiple Access (NOMA) provides resource efficiency with the potential of managing interference. In this thesis, a specific class of Balanced Incomplete Block designs called Steiner designs is analyzed. For this class, the decoding techniques are enhanced by exploiting the structure of these designs. However, decoding criteria for a large number of independent users is prohibitively expensive. Therefore, we provide an optimized way to search through all possible combinations of independent user data. Our work presents decoding users both from a performance oriented and objective oriented viewpoint. Work in physical layer techniques for non-orthogonal transmission is evolving. The need for finding a structured decoding scheme for large number of designs will pave the way for high data rate transmissions. Also, physical implementation and analysis of decoding techniques for a large number of users will bridge the gap between theory and practice.

Show moreUsing a sample of 109 managers and 307 direct reports from a global financial services firm headquartered in the United States, we examined how trustworthiness affected the relationship between authentic leadership and performance in followers. Additionally, we examined how trustworthiness drives performance in an environment of strategic and structural uncertainty. Our findings indicate that authentic leadership drives follower performance and that this relationship may be mediated by benevolence. However, in a post hoc analysis we did show that benevolence mediated the relationship between relational transparency and performance. While not conclusive, there is also evidence to suggest that structural uncertainty moderates the relationship between benevolence and performance. In an environment of high structural uncertainty, followers that perceive their leaders as benevolent tend to outperform other followers.

The result of the comparison of the level of Work Life Conflict of multi-job holders who were separated into two groups by how they perceived their work (i.e., solely to generate income, n=61; or to support pursuing a calling, n=40) and single-job holders (n=177) yielded no significant difference. The results of the moderators of availability via communication technology (CT) and schedule flexibility revealed a significant interaction effect between work type and availability via CT on WLC, indicating that higher levels of availability via CT exacerbate WLC for those pursuing callings compared to those holding jobs. Additionally, work identified as a calling correlated higher on WLC levels than work identified as a job. Implications and future directions are discussed.

Show moreIn this project, the utilization of virtualized reality environments to the guidance of blind or visually-impaired people will be explored. A virtualized reality environment will be constructed based on visual sensory information and described verbally to the user instead of presented to him graphically. One of two contexts will be selected: a static scenario in which the motorized sensors and the system are located in the environment; or a mobile scenario in which a wearable computing system is worn by the user. The technical side of the project requires students with programming skills capable and/or interested in: image analysis, computer graphics, artificial intelligence, and hardware interface and design. The non-technical side of the project requires students capable and/or interested in: analyzing the guidance needs of blind and visually-impaired people, analyzing and experimenting with different verbal descriptions of visual scenes, assessing the level of detail with which the user is comfortable, and experimenting with and assessing the effectiveness of different descriptive schemes. In the long term, the insight and ideas developed in this project may lead to their further development, testing and implementation in practical applications for those who are blind and visually-impaired or more generally for people to communicate and collaborate with each other more effectively in a virtual fashion.

Show moreLi-ion cells have demonstrated excellent performance when operated at ambient temperature conditions. Still, the adverse effect of temperature excursions on lithium-ion cell performance is evident when the cell is operated at elevated temperatures beyond 65 oC or at low temperatures below 0 oC. In all applications, e.g. for powering personal electronics or electric vehicles (EV), a number of cells are packed together in different configurations (parallel and series) to form a battery. It is important to keep the battery pack temperature within a fairly narrow temperature range for optimal battery performance. Thermal management for battery systems can be achieved using an IIT patented technology that incorporates phase change material (PCM) in the battery pack design. The PCM integrated in the cell and/or battery design will act as a heat sink for heat generated, for example during discharge of a Li-ion battery, which is a highly exothermic process. The heat stored will be evolved later when the battery temperature drops during battery charge, or under cold weather conditions. The objectives of this project is to design and test a 10 A-hr, 12 VDC lithium-ion battery module that can be used to power electric/hybrid vehicles(EV/HEV). The design and testing of the battery module will require a team of students with strong backgrounds in mechanical, chemical and electrical engineering. There will also be a need for law students to ensure proper protection of any new intellectual property generated from the project. A business student is required to conduct a market survey of these technologies, including the current market size and sales projections for the EV/HEV market.

The heat stored will be evolved later when the battery temperature drops during battery charge, or under cold weather conditions.The objectives of this project is to design and test a 10 A-hr, 12 VDC lithium-ion battery module that can be used to power electric/hybrid vehicles(EV/HEV). The design and testing of the battery module will require a team of students with strong backgrounds in mechanical, chemical and electrical engineering. There will also be a need for law students to ensure proper protection of any new intellectual property generated from the project. A business student is required to conduct a market survey of these technologies, including the current market size and sales projections for the EV/HEV market.

Show moreA French company has developed new technology for a wind turbine that produces significantly more energy for a given diameter. This company has agreed to donate a 12 kilowatt prototype unit for research purposes. The project will not only be directed to assessing the efficiency of the wind turbine, but also to the development of a unique stable energy source that integrates several renewable energy sources. The City of Chicago Department of Environment has agreed to partner with IIT in the development of this system. This IPRO team will be responsible for developing the research plan which will include but not be limited to: 1) identifying and assessing alternate locations for siting the wind turbine prototype, 2) developing the research protocol, 3) evaluating wind data in the Chicago area, 4) reviewing the legal aspects of the project including permitting requirements, 5) identifying potential contractors for the installation of the prototype, and 6) developing a preliminary design for the electrical generating system described above.
