Show moreImproving national ranking is an increasingly important issue for university administrators. While research has been conducted on performance measures in higher education, research designs have lacked a predictive quality. Studies on the U.S. News college rankings have provided insight into the methodology; however, none of them have provided a model to predict what change in variable values would likely cause an institution to improve its standing in the rankings. The purpose of this study was to develop a predictive model for benchmarking academic programs (pBAP) for engineering colleges. The 2005 U.S. News ranking data for graduate engineering programs were used to create a four-tier predictive model (pBAP). The pBAP model correctly classified 81.9% of the cases in their respective tier. To test the predictive accuracy of the pBAP model, the 2005 U.S .News data were entered into the pBAP variate developed using the 2004 U.S. News data. The model predicted that 88.9% of the institutions would remain in the same ranking tier in the 2005 U.S. News rankings (compared with 87.7% in the actual data), and 11.1% of the institutions would demonstrate tier movement (compared with an actual 12.3% movement in the actual data). The likelihood of improving an institution's standing in the rankings was greater when increasing the values of 3 of the 11 variables in the U.S. News model: peer assessment score, recruiter assessment score, and research expenditures.

Forty percent of employed parents report that they experience work-family conflict (Galinsky, Bond, & Friedman, 1993). Work-family conflict (WFC) exists when role pressures from the work and family domains are mutually incompatible. WFC is associated with decreases in family, job, and life satisfaction and physical health; intention to quit one's job; and increases in workplace absenteeism. Women may be more impacted by WFC than men, as women report completing 65-80% of the child care ...
Show moreForty percent of employed parents report that they experience work-family conflict (Galinsky, Bond, & Friedman, 1993). Work-family conflict (WFC) exists when role pressures from the work and family domains are mutually incompatible. WFC is associated with decreases in family, job, and life satisfaction and physical health; intention to quit one's job; and increases in workplace absenteeism. Women may be more impacted by WFC than men, as women report completing 65-80% of the child care (Sayer, 2001) and spend 80 hours per week fulfilling work and home responsibilities (Cowan, 1983). Research suggests that WFC can be reduced with social support, such as co-workers providing assistance when family interferes with work (Carlson & Perrewé, 1999). It is unclear whether parents 'get a break' or are penalized by co-workers. The purpose of the present study was to examine co-workers' reactions to individuals who experience WFC. Based on sex role theory and attribution theory, it was predicted that women, people who experience family interference with work, and those who have more control over the work interference would be helped less and evaluated more poorly on a team task than men, people who experience non-family related work interference, and those who have less control over the work interference. A laboratory experiment was conducted in which participants signed up for a team-based study. The teammate was a confederate who was late for the study. Teammate control over the tardiness (unexpected physician's visit versus forgotten physician's appointment), type of work conflict (self- versus family-related), and gender of the teammate were manipulated. After learning about the reasons for the tardiness of their teammate, the 218 participants (63% female; 59% Caucasian) decided whether to help the late teammate by completing a word sort task for them or letting the late teammate make up the work after the experiment. When the teammate arrived, the participants completed a team task and then evaluated the task performance of their teammate. None of the hypotheses were confirmed in this study. However, exploratory analyses showed that people who had more control over the tardiness were rated lower than people who had less control over the tardiness. Contrary to expectations, exploratory analyses also showed that men rated women who were late to the study for a family-related reason higher than women who were late due to a self-related reason. These findings suggest that male co-workers may give women a break when they experience family interference with work. Implications for future research and practice are discussed.

Show moreThe West Indian manatee (Trichechus manatus) is an herbivorous marine mammal that occupies freshwater, estuarine, and marine habitats. Despite being considered endangered, relatively little is known about the feeding ecology of either of the two recognized subspecies, the Florida manatee (T.m. latirostris) and Caribbean or Antillean manatee (T.m. manatus). A better understanding of their respective feeding preferences and habitat use is essential to establish criteria on which conservation plans can be based. The present study expands on previous work on manatee feeding ecology by both assessing the application of stable isotope analysis to manatee tissue and providing critical baseline parameters for accurate isotopic data interpretation. The present study was the first to calculate stable isotope turnover rate in the skin of any marine mammal. Stable carbon and nitrogen isotope ratios were examined over a period of more than one year in the epidermis of rescued Florida manatees that were transitioning from a diet of aquatic forage to terrestrial forage (lettuce) in captivity. Mean half-life for 13C turnover in manatee epidermis was 55 days and mean half-life for 15N turnover was 42 days. Due to these slow turnover rates, carbon and nitrogen stable isotope analysis in manatee epidermis is useful in summarizing average dietary intake over a long period of time rather than assessing recent diet. In addition to turnover rate, a diet-tissue discrimination value of 2.8 for 13C was calculated for long-term captive manatees on a lettuce diet. Turnover and diet-tissue discrimination results were subsequently used to interpret carbon and nitrogen stable isotope data in epidermis samples collected from free-ranging manatees in Florida, Belize, and Puerto Rico. This study was the first application of stable isotope analysis to Antillean manatees. Regional differences in stable isotope ratios in manatee skin were consistent with ratios in plant samples collected in those regions. Signatures in the skin of manatees sampled in Belize and Puerto Rico indicated a diet composed mainly of seagrasses, whereas those of Florida manatees exhibited greater variation. Mixing model results indicated manatees sampled from Crystal River and Homosassa Springs had an overall average intake of primarily freshwater vegetation whereas manatees sampled from Big Bend Power Plant, Ten Thousand Islands, and Warm Mineral Springs fed primarily on seagrasses. Possible diet-tissue discrimination values for 15N ranged from 1.0 to 1.5. Stable isotope analysis can be successfully applied to interpret manatee feeding behavior over a long period of time, specifically the use of freshwater vegetation vs. seagrasses, and can aid in improving conservation efforts.

Show moreThe purposes of the following thesis is to research United States Supreme Court sex-discrimination jurisprudence and ascertain if Fourteenth Amendment legislative history was used, referred to, cited to, or quoted from, by the Supreme Court Justices in their opinions regarding sex-discrimination cases since the Amendment was ratified in 1868. Legislative history is a window into the drafting, debating, and intricate crafting of laws and amendments. When words and phrases that are used in the statutes, codes, and amendments are ambiguous or unclear, judges and justices should use the legislative history to ascertain the intent of the framers of the legislation. The methodology that was employed for this thesis was through the researching of all relevant United States Supreme Court cases as to what was written by the Justices in their opinions. Research was conducted into the relevant law review articles on the subject of legislative history of the Fourteenth Amendment, Supreme Court sex-discrimination jurisprudence, and the historical impact of Court decisions on the law relative to sex-discrimination. After extensive research, it was discovered that the United States Supreme Court has established over 144 years' worth of sex-discrimination jurisprudence. The law review article research revealed that the lack of legislative history research by the Court has not gone unnoticed by the legal community or the women's rights community since the Fourteenth Amendment was originally drafted. The research and analysis of the sources of sex-discrimination from cases, law review articles, and books on the subject, led to the conclusion that no Fourteenth Amendment legislative history was ever used by the Supreme Court of the United States as part of its development of sex-discrimination jurisprudence.

Show moreThe older population is growing rapidly and businesses must prepare for changes in their workforce. Cases of age discrimination have also become more common. Older workers are being forced out of their jobs at a faster rate than any other age group. As a result, older workers commonly take jobs in different careers, where they compete with younger workers who have similar relevant experience and are valued for their youth. Both prototype matching theory and career timetables theory state that people hold stereotypes of the job in addition to stereotypes of people. In laboratory research, a mismatch between the age of the worker and the age-type of the job has led to lower evaluations, lower job suitability ratings, and other indicators of discrimination. The purpose of this thesis is to assess whether the construct of age-type is related to discrimination in real-world legal cases. Real life instances of discrimination were attained from a 15-year sample of 388 age discrimination jury verdicts and settlements. Each job in the sample of cases was rated to determine age-type, perceived proportion of older and younger workers in the job, and importance of stereotypically older worker features to the job. Results showed that all forms of age stereotypes, both general and specific, were related to the frequency of cases in jobs associated with older or younger stereotypes. Specifically, older workers were more likely to have age discrimination cases go to trial in younger age-typed jobs. However, these variables did not help to predict formal outcomes of the cases (win vs. loss). Among the cases that did win, cases in older age-typed jobs won significantly more money than in younger age-typed jobs.

Show moreThe goal of this dissertation was to bridge the gap between perceptual learning theory and training application. Visual perceptual skill has been a vexing topic in training science for decades. In complex task domains, from aviation to medicine, visual perception is critical to task success. Despite this, little, if any, emphasis is dedicated to developing perceptual skills through training. Much of this may be attributed to the perceived inefficiency of perceptual training. Recent applied research in perceptual training with discrimination training, however, holds promise for improved perceptual training efficiency. As with all applied research, it is important to root application in solid theoretical bases. In perceptual learning, the challenge is connecting the basic science to more complex task environments. Using a common aviation task as an applied context, participants were assigned to a perceptual training condition based on variation of image complexity and training type. Following the training, participants were tested for transfer of skill. This was intended to help to ground a potentially useful method of perceptual training in a model category learning, while offering qualitative testing of model fit in increasingly complex visual environments. Two hundred and thirty-one participants completed the computer based training module. Results indicate that predictions of a model of category learning largely extend into more complex training stimuli, suggesting utility of the model in more applied contexts. Although both training method conditions showed improvement across training blocks, the discrimination training condition did not transfer to the post training transfer tasks. Lack of adequate contextual information related to the transfer task in training was attributed to this outcome. Further analysis of the exposure training condition showed that individuals training with simple stimuli performed as well as individuals training on more complex stimuli in a complex transfer task. On the other hand, individuals in the more complex training conditions were less accurate when presented with a simpler representation of the task in transfer. This suggests training benefit to isolating essential task cues from irrelevant information in perceptual judgment tasks. In all, the study provided an informative look at both the theory and application associated with perceptual category learning. Ultimately, this research can help inform future research and training development in domains where perceptual judgment is critical for success.

Show moreThis dissertation investigates the role of two marketing practices---returns policies and group-buying services---in improving channel coordination. The first study (presented in Chapter Two) focuses on the interaction between two types of returns policies---returns of unwanted products from consumers to retailers and returns of unsold inventory from retailers to manufacturers. Even without the right to return unsold inventory to the manufacturer, the retailers may accept returns from consumers; by doing so, they benefit from a less price-sensitive market demand, an ability to screen for high-valuation consumers, and a competitive advantage (offering a returns policy makes a retailer more attractive to consumers). From the manufacturer's perspective, accepting returns may induce the retailers to order more stock, set lower prices, generate more sales, and therefore, improves the performance of the channel. However, under some conditions (e.g., when the marginal cost of stock-outs is relatively high), this study shows that this effect disappears and the manufacturer does not accept returns from the retailer in equilibrium. The second study (presented in Chapter Three) investigates the rationale for using group-buying services vis-a-vis the traditional posted-pricing mechanism. It focuses on the behavior of consumers and explores the role of heterogeneity in their valuation for the product and cost of purchasing via group-buying in the functioning of group-buying services as a price-discrimination device. Finally, the role of group-buying services in improving channel coordination under asymmetric information is studied in Chapter Four. This analysis shows that the availability of group-buying services provides an opportunity for the manufacturer to reduce the informational rents of the retailer arising from its private information about the market condition. Interestingly, the manufacturer can avoid paying these rents and regains the first-best profitability when asymmetry in information exists regarding the relative sizes of consumer segments. In other settings (e.g., when asymmetric information exists regarding consumers' price sensitivity), leveraging the group-buying mechanism nevertheless allows the manufacturer to design a contract that requires lower rents and improves channel coordination to some extent.

Show moreIdentification of osseous materials is generally established on gross anatomical factors; however, highly fragmented or taphonomically altered materials are often problematic and alternative methods, such as biological, histological, or chemical analysis, must be utilized. Recently, chemical methods have been proposed to sort unknown materials according to their Ca/P ratios. Ubelaker and colleagues (2002) proposed using SEM/EDX to achieve this distinction and Christensen and colleagues (2012) have validated X-ray Fluorescence Spectrometry (XRF) for this application. An alternative method of analysis involves performing principal component analysis (PCA) on element spectra to classify unknown materials based on their trace element composition. Zimmerman (2013) proposed the validity of this method with data obtained using hand held XRF. Subsequently, performing PCA on elemental data obtained using SEM/EDX demonstrates potential for material differentiation. Elemental weight percent data were collected using SEM/EDX then processed in R, version 3.0.1, by the R Foundation for Statistical Computing using PCA and Fisher Linear Discriminant Analysis. A two-tiered analysis was undertaken to improve discrimination between sample groups. The first tier involved distinguishing between osseous and non-osseous materials. After outliers were removed overall correct classification was 98.02% with one of 1504 osseous and 39 of 520 non-osseous spectra misclassifying. Since forty spectra were collected for each sample, the single misclassifying spectra would not affect the overall classification of the sample, resulting in 100% correct classification with a 0% error rate for the osseous samples. The second tier assessed differentiation of human and non-human osseous materials but demonstrated a poor correct classification rate of 72.41%. Finally, a blind study was conducted using 20 samples to assess the applicability for using this method to classify unknown materials as osseous or non-osseous. All of the samples were correctly classified resulting in 100% correct classification, further demonstrating the efficiency of SEM/EDX and statistical analysis for differentiation of osseous and non-osseous materials. Due to its high specificity, small sample requirements, and relative non-destructive testing protocol, as well as its presence in most modern crime laboratories, SEM/EDX has been proposed as a laboratory method for chemical differentiation of osseous and non-osseous materials. Additionally, the proposed method does not require advanced training or knowledge of analytical chemistry as the SEM/EDX provides clear results that can be processed using publically available statistical analysis software. By assessing and improving chemical analysis methodologies used for material differentiation, forensic anthropologists might be able to identify osseous and non-osseous samples as a preemptive step in forensic investigations involving fragmentary and taphonomically modified materials, reducing time and cost investments spent on forensically insignificant samples.

Show moreSmokeless powders are a set of energetic materials, known as low explosives, which are typically utilized for reloading ammunition. There are three types which differ in their primary energetic materials; where single base powders contain nitrocellulose as their primary energetic material, double and triple base powders contain nitroglycerin in addition to nitrocellulose, and triple base powders also contain nitroguanidine. Additional organic compounds, while not proprietary to specific manufacturers, are added to the powders in varied ratios during the manufacturing process to optimize the ballistic performance of the powders. The additional compounds function as stabilizers, plasticizers, flash suppressants, deterrents, and opacifiers. Of the three smokeless powder types, single and double base powders are commercially available, and have been heavily utilized in the manufacture of improvised explosive devices.Forensic smokeless powder samples are currently analyzed using multiple analytical techniques. Combined microscopic, macroscopic, and instrumental techniques are used to evaluate the sample, and the information obtained is used to generate a list of potential distributors. Gas chromatography (-) mass spectrometry (GC-MS) is arguably the most useful of the instrumental techniques since it distinguishes single and double base powders, and provides additional information about the relative ratios of all the analytes present in the sample. However, forensic smokeless powder samples are still limited to being classified as either single or double base powders, based on the absence or presence of nitroglycerin, respectively. In this work, the goal was to develop statistically valid classes, beyond the single and double base designations, based on multiple organic compounds which are commonly encountered in commercial smokeless powders. Several chemometric techniques were applied to smokeless powder GC-MS data for determination of the classes, and for assignment of test samples to these novel classes. The total ion spectrum (TIS), which is calculated from the GC-MS data for each sample, is obtained by summing the intensities for each mass-to-charge (m/z) ratio across the entire chromatographic profile. A TIS matrix comprising data for 726 smokeless powder samples was subject to agglomerative hierarchical cluster (AHC) analysis, and six distinct classes were identified. Within each class, a single m/z ratio had the highest intensity for the majority of samples, though the m/z ratio was not always unique to the specific class. Based on these observations, a new classification method known as the Intense Ion Rule (IIR) was developed and used for the assignment of test samples to the AHC designated classes.Discriminant models were developed for assignment of test samples to the AHC designated classes using k-Nearest Neighbors (kNN) and linear and quadratic discriminant analyses (LDA and QDA, respectively). Each of the models were optimized using leave-one-out (LOO) and leave-group-out (LGO) cross-validation, and the performance of the models was evaluated by calculating correct classification rates for assignment of the cross-validation (CV) samples to the AHC designated classes. The optimized models were utilized to assign test samples to the AHC designated classes. Overall, the QDA LGO model achieved the highest correct classification rates for assignment of both the CV samples and the test samples to the AHC designated classes.In forensic application, the goal of an explosives analyst is to ascertain the manufacturer of a smokeless powder sample. In addition, knowledge about the probability of a forensic sample being produced by a specific manufacturer could potentially decrease the time invested by an analyst during investigation by providing a shorter list of potential manufacturers. In this work, Bayes' Theorem and Bayesian Networks were investigated as an additional tool to be utilized in forensic casework. Bayesian Networks were generated and used to calculate posterior probabilities of a test sample belonging to specific manufacturers. The networks were designed to include manufacturer controlled powder characteristics such as shape, color, and dimension; as well as, the relative intensities of the class associated ions determined from cluster analysis. Samples were predicted to belong to a manufacturer based on the highest posterior probability. Overall percent correct rates were determined by calculating the percentage of correct predictions; that is, where the known and predicted manufacturer were the same. The initial overall percent correct rate was 66%. The dimensions of the smokeless powders were added to the network as average diameter and average length nodes. Addition of average diameter and length resulted in an overall prediction rate of 70%.

Show moreThis is an exploratory, qualitative study of female musicians and their experiences with discrimination in the music industry. Using semi-structured interviews, I analyze the experiences of nine women, ages 21 to 56, who are working as professional musicians, or who have worked professionally in the past. I ask them how they are treated differently based on their gender. Three forms of subtle discrimination are inferred from their narrative histories. First, female musicians are mistaken for non-musicians. They are encapsulated into inferior roles, like "the gimmick," "good for a girl," and "invisible accessory." Second, band mates and band managers control women's space, success, and artistic freedom. Third, their femininity, sexuality, and age are highly scrutinized. The analysis implies that female musicians are tokenized, devalued, and considered inappropriate for their jobs. Particular attention is paid to the similarities between female musicians and women in male dominated work places. I conclude by discussing the larger implications for gender, music, and social change in a sexist, unregulated industry.

This study focuses specifically on the field of journalism and how female reporters used the courts to fight the gender discrimination that was widespread and unbridled before the creation of legislation that outlawed it. The lawsuit filed by Mary Lou Butcher and approximately 90 other women against The Detroit News is one such case that exemplifies the process of filing a gender discrimination lawsuit, as well as the events that led to the suits and the impact that it and similar lawsuits had on the field of journalism and the women's liberation movement as a whole. Using textual analysis to examine the coverage of these lawsuits by industry literature and by the publications challenged by the lawsuits demonstrates what the field of newspapers and magazines was like during the time of the cases. Comparing the same media during the times of the lawsuits and post-settlement reveal how they contributed to an adjusted view of female journalists and aided women's acceptance in American newsrooms.

Show moreThere are proportionally fewer Hispanic Americans, African Americans and women in Congress than in the United States population. Existing literature prescribes a variety of explanations for this disparity including skewed nominations procedures, differing participation rates, racial gerrymandering, voting biases, and funding inequities. This study revisits one aspect of the underrepresentation issue: campaign contributions. Money has been an integral component of the electoral process since before the American Revolution and its impact on the current composition of Congress ought to be explored to a greater extent. Previous research shows that contributors rarely, if at all, discriminate on the basis of gender. This study intends to further investigate the congressional campaign funding of African Americans and provide some much needed insight regarding the campaign financing of Hispanic American candidates. Using financial and biographical data from each candidate within the 2004 and 2008 election cycles, a multiple regression model will be employed to evaluate the extent to which gender and minority status determine the distribution of congressional campaign funds independent of other electability traits considered influential by contributors (the percentage of vote received in the last election, incumbency, and the leadership position held are indications of candidate strength that affect campaign contributions). The magnitude and statistical significance of these coefficients provides further understanding into funding inequities.

Show moreThe purpose of the current study was to investigate the relationship between first-generation college students' (FGCSs) help-seeking attitudes, as measured by the Attitudes Towards Seeking Professional Psychological Help (-) Short Form (Fischer (&) Farina, 1995); public stigma, as measured by the Perceptions of Stigmatization by Others for Seeking Psychological Help (Vogel, Wade, (&) Ascheman, 2009); personal stigma, as measured by the Self-Stigma of Seeking Help Scale Working (Vogel, Wade, (&) Haake, 2006); social support, as measured by the Multidimensional Scale of Perceived Social Support (Dahlem, Zimet, (&) Walker, 1991); and perceived discrimination, as measured by the revised Everyday Discrimination Scale (Stucky et al., 2011). The researcher further investigated mediating effects of public and personal stigma in the relationships among the constructs. The researcher found statistically significant relationships among the variables for FGCSs and mediating effects of personal and public stigma. Specifically, public stigma mediated the relationship between perceived discrimination and personal stigma and the indirect effect of perceived discrimination on personal stigma via public stigma was statistically significant ((&)#223; = .070, p = .030). Personal stigma also fully mediated the relationship between public stigma and help-seeking attitudes and the indirect effect of public stigma on help-seeking attitudes via personal stigma was statistically significant ((&)#223; = -.231, p (<) .001). Public stigma partially mediated the relationship between social support and personal stigma and the indirect effect of social support on personal stigma via public stigma ((&)#223; = -.089, p = .010) was statistically significant. In addition, both public and personal stigma partially mediated the relationship between social support and help-seeking attitudes. The indirect effect of social support on help-seeking attitudes via both public and personal stigma was statistically significant ((&)#223; = .062, p = .015). The researcher presented discussion of results, limitations of the study, and implications of the findings.

Show moreLaser Induced Breakdown Spectroscopy (LIBS) is showing great potential as an atomic analytical technique. With its ability to rapidly analyze all forms of matter, with little-to-no sample preparation, LIBS has many advantages over conventional atomic emission spectroscopy techniques. With the maturation of the technologies that make LIBS possible, there has been a growing movement to implement LIBS in portable analyzers for field applications. In particular, LIBS has long been considered the front-runner in the drive for stand-off detection of trace deposits of explosives. Thus there is a need for a better understanding of the relevant processes that are responsible for the LIBS signature and their relationships to the different system parameters that are helping to improve LIBS as a sensing technology. This study explores the use of LIBS as a method to detect random trace amounts of specific organic materials deposited on organic or non-metallic surfaces. This requirement forces the limitation of single-shot signal analysis. This study is both experimental and theoretical, with a sizeable component addressing data analysis using principal components analysis to reduce the dimensionality of the data, and quadratic discriminant analysis to classify the data. In addition, the alternative approach of 'target factor analysis' was employed to improve detection of organic residues on organic substrates. Finally, a new method of characterizing the laser-induced plasma of organics, which should lead to improved data collection and analysis, is introduced. The comparison between modeled and experimental measurements of plasma temperatures and electronic density is discussed in order to improve the present models of low-temperature laser induced plasmas.

Show moreThis study sought to explore the challenges faced by older workers who do not fit the age-type of their jobs and how older workers adapt to overcome those challenges. Specifically, I surveyed a national sample of 227 workers 50 years of age and older, in a wide variety of jobs, on measures of perceived age discrimination and adaptation behaviors. I found that fit, as determined by career timetables theory, but not prototype matching theory, successfully predicted perceived age discrimination. Specifically, more age discrimination was perceived when fewer older workers occupied a job. Additionally, multiple regression analysis showed that career timetables theory, prototype matching theory, and measures of perceived discrimination interacted to predict adaptation behaviors. That is, older workers made more efforts appear younger at work when they perceived age discrimination in jobs occupied by fewer older workers and older women expressed greater desires to appear younger at work when they perceived age discrimination in jobs viewed as more appropriate for younger workers. Although older workers made a wide variety of efforts to appear younger at work, from changing the way they dressed to undergoing surgical procedures, the adaptation efforts believed to be the most effective against age discrimination were more oriented toward enhancing job performance than one's appearance. It is especially troubling that greater perceived age discrimination was found in young-typed jobs (than in old-typed jobs) given that the number of older workers occupying young-typed jobs is expected to rapidly grow in the near future and perceived discrimination is associated with mental and physical consequences for older adults. Understanding effective adaptations to age discrimination is a valuable first step in helping older workers overcome the disadvantages they may face in the workplace, especially when they occupy young-typed jobs. Implications for theory and research are discussed.

Show moreFire debris analysis currently relies on visual pattern recognition of the total ion chromatograms, extracted ion profiles, and target compound chromatograms to identify the presence of an ignitable liquid according to the ASTM International E1618-10 standard method. For large data sets, this methodology can be time consuming and is a subjective method, the accuracy of which is dependent upon the skill and experience of the analyst. This research aimed to develop an automated classification method for large data sets and investigated the use of the total ion spectrum (TIS). The TIS is calculated by taking an average mass spectrum across the entire chromatographic range and has been shown to contain sufficient information content for the identification of ignitable liquids. The TIS of ignitable liquids and substrates, defined as common building materials and household furnishings, were compiled into model data sets. Cross-validation (CV) and fire debris samples, obtained from laboratory-scale and large-scale burns, were used to test the models. An automated classification method was developed using computational software, written in-house, that considers a multi-step classification scheme to detect ignitable liquid residues in fire debris samples and assign these to the classes defined in ASTM E1618-10. Classifications were made using linear discriminant analysis, quadratic discriminant analysis (QDA), and soft independent modeling of class analogy (SIMCA). Overall, the highest correct classification rates were achieved using QDA for the first step of the scheme and SIMCA for the remaining steps. In the first step of the classification scheme, correct classification rates of 95.3% and 89.2% were obtained for the CV test set and fire debris samples, respectively. Correct classifications rates of 100% were achieved for both data sets in the majority of the remaining steps which used SIMCA for classification. In this research, the first statistically valid error rates for fire debris analysis have been developed through cross-validation of large data sets. The error rates reduce the subjectivity associated with the current methods and provide a level of confidence in sample classification that does not currently exist in forensic fire debris analysis.

Show moreThe National Academy of Sciences recently published a report which calls for improvements to the field of forensic science. Their report criticized many forensic disciplines for failure to establish rigorously-tested methods of comparison, and encouraged more research in these areas to establish limitations and assess error rates. This study applies chemometric and statistical methods to current and developing analytical techniques in fiber analysis. In addition to analysis of commercially available dyed textile fibers, two pairs of dyes are selected for custom fabric dyeing based on the similarities of their absorbance spectra and dye molecular structures. Visible absorption spectra for all fiber samples are collected using microspectrophotometry (MSP) and mass spectra are collected using electrospray ionization (ESI) mass spectrometry. Statistical calculations are performed using commercial software packages and software written in-house. Levels of Type I and Type II error are examined for fiber discrimination based on hypothesis testing of visible absorbance spectra profiles using a nonparametric permutation method. This work also explores evaluation of known and questioned fiber populations based on an assessment of statistical p-value distributions from questioned-known fiber comparisons with those of known fiber self-comparisons. Results from the hypothesis testing are compared with principal components analysis (PCA) and discriminant analysis (DA) of visible absorption spectra, as well as PCA and DA of ESI mass spectra. The sensitivity of a statistical approach will also be discussed in terms of how instrumental parameters and sampling methods may influence error rates.

Show moreRecently, Attention Deficit Hyperactive Disorder (ADHD) is getting a lot of attention mainly for two reasons. First, it is one of the most commonly found childhood behavioral disorders. Around 5-10% of the children all over the world are diagnosed with ADHD. Second, the root cause of the problem is still unknown and therefore no biological measure exists to diagnose ADHD. Instead, doctors need to diagnose it based on the clinical symptoms, such as inattention, impulsivity and hyperactivity, which are all subjective.Functional Magnetic Resonance Imaging (fMRI) data has become a popular tool to understand the functioning of the brain such as identifying the brain regions responsible for different cognitive tasks or analyzing the statistical differences of the brain functioning between the diseased and control subjects. ADHD is also being studied using the fMRI data. In this dissertation we aim to solve the problem of automatic diagnosis of the ADHD subjects using their resting state fMRI (rs-fMRI) data.As a core step of our approach, we model the functions of a brain as a connectivity network, which is expected to capture the information about how synchronous different brain regions are in terms of their functional activities. The network is constructed by representing different brain regions as the nodes where any two nodes of the network are connected by an edge if the correlation of the activity patterns of the two nodes is higher than some threshold. The brain regions, represented as the nodes of the network, can be selected at different granularities e.g. single voxels or cluster of functionally homogeneous voxels. The topological differences of the constructed networks of the ADHD and control group of subjects are then exploited in the classification approach.We have developed a simple method employing the Bag-of-Words (BoW) framework for the classification of the ADHD subjects. We represent each node in the network by a 4-D feature vector: node degree and 3-D location. The 4-D vectors of all the network nodes of the training data are then grouped in a number of clusters using K-means; where each such cluster is termed as a word. Finally, each subject is represented by a histogram (bag) of such words. The Support Vector Machine (SVM) classifier is used for the detection of the ADHD subjects using their histogram representation. The method is able to achieve 64% classification accuracy.The above simple approach has several shortcomings. First, there is a loss of spatial information while constructing the histogram because it only counts the occurrences of words ignoring the spatial positions. Second, features from the whole brain are used for classification, but some of the brain regions may not contain any useful information and may only increase the feature dimensions and noise of the system. Third, in our study we used only one network feature, the degree of a node which measures the connectivity of the node, while other complex network features may be useful for solving the proposed problem.In order to address the above shortcomings, we hypothesize that only a subset of the nodes of the network possesses important information for the classification of the ADHD subjects. To identify the important nodes of the network we have developed a novel algorithm. The algorithm generates different random subset of nodes each time extracting the features from a subset to compute the feature vector and perform classification. The subsets are then ranked based on the classification accuracy and the occurrences of each node in the top ranked subsets are measured. Our algorithm selects the highly occurring nodes for the final classification. Furthermore, along with the node degree, we employ three more node features: network cycles, the varying distance degree and the edge weight sum. We concatenate the features of the selected nodes in a fixed order to preserve the relative spatial information. Experimental validation suggests that the use of the features from the nodes selected using our algorithm indeed help to improve the classification accuracy. Also, our finding is in concordance with the existing literature as the brain regions identified by our algorithms are independently found by many other studies on the ADHD. We achieved a classification accuracy of 69.59% using this approach. However, since this method represents each voxel as a node of the network which makes the number of nodes of the network several thousands. As a result, the network construction step becomes computationally very expensive. Another limitation of the approach is that the network features, which are computed for each node of the network, captures only the local structures while ignore the global structure of the network.Next, in order to capture the global structure of the networks, we use the Multi-Dimensional Scaling (MDS) technique to project all the subjects from an unknown network-space to a low dimensional space based on their inter-network distance measures. For the purpose of computing distance between two networks, we represent each node by a set of attributes such as the node degree, the average power, the physical location, the neighbor node degrees, and the average powers of the neighbor nodes. The nodes of the two networks are then mapped in such a way that for all pair of nodes, the sum of the attribute distances, which is the inter-network distance, is minimized. To reduce the network computation cost, we enforce that the maximum relevant information is preserved with minimum redundancy. To achieve this, the nodes of the network are constructed with clusters of highly active voxels while the activity levels of the voxels are measured based on the average power of their corresponding fMRI time-series. Our method shows promise as we achieve impressive classification accuracies (73.55%) on the ADHD-200 data set. Our results also reveal that the detection rates are higher when classification is performed separately on the male and female groups of subjects.So far, we have only used the fMRI data for solving the ADHD diagnosis problem. Finally, we investigated the answers of the following questions. Do the structural brain images contain useful information related to the ADHD diagnosis problem? Can the classification accuracy of the automatic diagnosis system be improved combining the information of the structural and functional brain data? Towards that end, we developed a new method to combine the information of structural and functional brain images in a late fusion framework. For structural data we input the gray matter (GM) brain images to a Convolutional Neural Network (CNN). The output of the CNN is a feature vector per subject which is used to train the SVM classifier. For the functional data we compute the average power of each voxel based on its fMRI time series. The average power of the fMRI time series of a voxel measures the activity level of the voxel. We found significant differences in the voxel power distribution patterns of the ADHD and control groups of subjects. The Local binary pattern (LBP) texture feature is used on the voxel power map to capture these differences. We achieved 74.23% accuracy using GM features, 77.30% using LBP features and 79.14% using combined information.In summary this dissertation demonstrated that the structural and functional brain imaging data are useful for the automatic detection of the ADHD subjects as we achieve impressive classification accuracies on the ADHD-200 data set. Our study also helps to identify the brain regions which are useful for ADHD subject classification. These findings can help in understanding the pathophysiology of the problem. Finally, we expect that our approaches will contribute towards the development of a biological measure for the diagnosis of the ADHD subjects.

Show moreThe rise of research on workplace mistreatment in the past twenty years can be attributed to the realization that workplace mistreatment is associated with a host of deleterious outcomes for both the individual targets of the mistreatment and the organizations in which they work. However, the extant literature is failing to capture the full range of sex-based mistreatment that people may experience through a tendency to focus solely on sexual harassment and sex discrimination, which are very specific types of behavior based on one's sex and gender stereotypes. In this dissertation, I introduce the construct of Not Woman Enough Harassment, or the extent to which women perceive that they are treated unfavorably because they do not meet traditionally held stereotypes of femininity. A scale was developed and validated in order to measure this type of harassment, and a model from antecedent to outcome was proposed. Results demonstrated that not woman enough harassment was experienced by approximately 32.5% of the sample. The scale showed good psychometric properties, with two distinct factors of harassment based on physical and non-physical traits. Not woman enough harassment was demonstrated to be distinct from other forms of sexual and workplace harassment. Discomfort with gender norm conformity and masculine physical and non-physical expression were shown to be antecedents of not woman enough harassment, along with a moderating effect of job gender context. In addition, not woman enough harassment significantly predicted decreased job satisfaction, affective organizational commitment, and task performance and increased withdrawal and job stress. Similar patterns were found for males with not man enough harassment.
