Determinants of the Applications to the Institutional Care in Turkey: Darulaceze Example
Although institutional care has started to be outmoded in the developed countries with development of different models of care, it still has a considerable place in the developing countries such as Turkey. This is because, changes in the demographic structure, extended family, and urban development of Turkey has brought about several aging problems leading older adults to end up in institutions. Loneliness was one of the significant reasons given in the Social Inquiry Survey of Applicants of Darulaceze Old-Age Institution and the basis for a micro level analysis in this study. Therefore, the main objective of the study was to determine the predictors of loneliness, including age, the state of living alone, functional independence, education, and gender. Analysis of the results indicated that these predictors have significant effects on the loneliness predominantly defined by social factors rather than medical factors. In addition, the meso and macro level analyses were employed to control the micro level analysis and see a general picture of institutional care. Thus, an academic example of diagnosing the main reasons behind the institutional care was presented to understand the context of aging in Turkey.
Connecting the Circuit: Analyzing Jurors' Cognitive Gaps and Damage Awards in Patent Infringement Trials
Patent litigation is notorious for the technicality of evidence and the rhetoric of experts. Citizens selected to serve on the jury have no specialized training and have rarely been exposed to the technology or the patent process. This study provides insight into the field of jury decision-making in complex patent cases by analyzing the cognitive gaps and the tactics used by jurors to minimize them. Additionally, the study examines the justifications for the damage awards jurors provide. This analysis focused on jurors engaged in mock trial patent deliberations. The story model and sensemaking theory serve as the theoretical framework of this research and provide a structure for support and a lens for analysis. The results indicate that jurors rely on three distinct and dichotomous topologies when navigating cognitive gaps. Searching for answers either individually or as a group, relying on lists or stories, and turning to facts or emotions, jurors navigate through their uncertainty. Through the line-by-line analysis of mock jury transcriptions, three continuums regarding damage justifications emerged. Jury members found themselves navigating uncertainty versus certainty, rationality versus irrationality, and facts versus emotions. The theoretical implications broaden the story model to include cognitive gaps in all phases and increase the model's efficacy in patent litigation through the addition of a fourth phase. This study also confirms and enhances the use of sensemaking to describe the jury decision-making process. The results of this study should be applied practically to the field of patent litigation. Results should be used to create a user-friendly environment where the high stakes of litigation demand increased juror understanding and are critical to justice.
Exploring the Evolutionary History of North American Prairie Grouse (Genus: Tympanuchus) Using Multi-locus Coalescent Analyses
Conservation biologists are increasingly using phylogenetics as a tool to understand evolutionary relationships and taxonomic classification. The taxonomy of North American prairie grouse (sharp-tailed grouse, T. phasianellus; lesser prairie-chicken, T. pallidicinctus; greater prairie-chicken, T. cupido; including multiple subspecies) has been designated based on physical characteristics, geography, and behavior. However, previous studies have been inconclusive in determining the evolutionary history of prairie grouse based on genetic data. Therefore, additional research investigating the evolutionary history of prairie grouse is warranted. In this study, ten loci (including mitochondrial, autosomal, and Z-linked markers) were sequenced across multiple populations of prairie grouse, and both traditional and coalescent-based phylogenetic analyses were used to address the evolutionary history of this genus. Results from this study indicate that North American prairie grouse diverged in the last 200,000 years, with species-level taxa forming well-supported monophyletic clades in species tree analyses. With these results, managers of the critically endangered Attwater's prairie-chicken (T. c. attwateri) can better evaluate whether outcrossing Attwater's with greater prairie-chickens would be a viable management tool for Attwater's conservation.
Is There Justice in Mercy? the Retributive Philosophies of Executive Clemency
Executive clemency is assumed to be a mechanism to correct miscarriages of justice brought about by the criminal justice system, yet little empirical research exists to confirm this assumption. This research study examined the types of rationales cited in 799 cases of executive clemency from six states from 2005 to 2012. Rationales based upon retributive philosophies, in which a miscarriage of justice was cited, were further analyzed. This analysis revealed that only seven percent of all clemency decisions from the examined states cited retributive rationales. Of the fifty-six grants of clemency that cited retributive rationales, most were granted in the forms of pardons. The analysis indicated that executive clemency is utilized as a mechanism to correct injustices, specifically in cases of innocence. This study concludes with a discussion of policy implications and the reliance on executive clemency as a fail-safe to the criminal justice system.
Exploring Memristor Based Analog Design in Simscape
With conventional CMOS technologies approaching their scaling limits, researchers are actively investigating alternative technologies for ever increasing computing and mobile demand. A number of different technologies are currently being studied by different research groups. In the last decade, one-dimensional (1D) carbon nanotubes (CNT), graphene, which is a two-dimensional (2D) natural occurring carbon rolled in tubular form, and zero-dimensional (0D) fullerenes have been the subject of intensive research. In 2008, HP Labs announced a ground-breaking fabrication of memristors, the fourth fundamental element postulated by Chua at the University of California, Berkeley in 1971. In the last few years, the memristor has gained a lot of attention from the research community. In-depth studies of the memristor and its analog behavior have convinced the community that it has the potential in future nano-architectures for optimization of high-density memory and neuromorphic computing architectures. The objective of this thesis is to explore memristors for analog and mixed-signal system design using Simscape. This thesis presents a memristor model in the Simscape language. Simscape has been used as it has the potential for modeling large systems. A memristor based programmable oscillator is also presented with simulation results and characterization. In addition, simulation results of different memristor models are presented which are crucial for the detailed understanding of the memristor along with its properties.
Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies
Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.
The Sex Offender Registry in Collin County, Texas: a Descriptive Analysis of Sex Offenders
The primary goal of this study was to analyze the characteristics of current registered sex offenders in Collin County, Texas, as well as to compare age and gender of the victims of these offenders in order to know who sex offenders primarily target in these crimes. The study also sought to discover geographic patterns of where the registered sex offenders reside for the purpose of keeping communities aware. Participants consisted of 175 registered sex offenders (N = 175) in Collin County, Texas, found on Collin County's and the Texas Department of Public Safety's online public registries. The findings demonstrate that there were significant trends among the sex offenders, their victims, location of residence, and housing complications as a result of progressing sex offender laws. Treatment programs and the reintegration of offenders in the community were also addressed. The meaning of the results in this study can aid in the development of safety and prevention strategies, provide an understanding about the utilization of sex offender registries, and can benefit law enforcement to predict the movement of current sex offenders, along with knowing where to find other potential offenders.
Criticality in Cooperative Systems
Cooperative behavior arises from the interactions of single units that globally produce a complex dynamics in which the system acts as a whole. As an archetype I refer to a flock of birds. As a result of cooperation the whole flock gets special abilities that the single individuals would not have if they were alone. This research work led to the discovery that the function of a flock, and more in general, that of cooperative systems, surprisingly rests on the occurrence of organizational collapses. In this study, I used cooperative systems based on self-propelled particle models (the flock models) which have been proved to be virtually equivalent to sociological network models mimicking the decision making processes (the decision making model). The critical region is an intermediate condition between a highly disordered state and a strong ordered one. At criticality the waiting times distribution density between two consecutive collapses shows an inverse power law form with an anomalous statistical behavior. The scientific evidences are based on measures of information theory, correlation in time and space, and fluctuation statistical analysis. In order to prove the benefit for a system to live at criticality, I made a flock system interact with another similar system, and then observe the information transmission for different disturbance values. I proved that at criticality the transfer of information gets the maximal efficiency. As last step, the flock model has been shown that, despite its simplicity, is sufficiently a realistic model as proved via the use of 3D simulations and computer animations.
Pasados Fragmentados:la Representación Teatral Del Robo De Niños En Las Dictaduras Española Y Argentina En Obras De Laila Ripoll Y Patricia Suárez
This study examines the theatrical representation of the stealing of children during the last dictatorships in Spain and in Argentina in Laila Ripoll's Los niños perdidos and Patricia Suárez's Astianacte: una máscara del amor under the lenses of the concepts of trauma, myth and memory. Following the theories suggested by Freud, Adorno, Whitehead, Reyes Mate and others, the first chapter discusses the representation of the psychological traumas left by the dictatorial practices left not only on the minds of individuals but also on both nations as whole entities. While Ripoll invites her audience to reflect upon the consequences of the Spanish Civil War and franquism, Patricia Suárez urges her spectators to doubt about their own identity if they were born during the last dictatorship in Argentina. In chapter two, the concepts advanced by Barthes, Reig Tapia and Moreno-Nuño help explore the ways in which the playwrights condemn the legitimizing myths that gave birth to these dictatorial regimes. Both authors subvert these fictional stories, mainly by the use of sarcasm and humor. By means of the concepts of memory supported by Benjamin, Todorov, Nora and Juliá, the third chapter examines the need to let the traditionally silenced voices tell their version of the historical events. Ripoll and Suárez warn their audiences that it is impossible to achieve one collective national memory because there are individual conflicting memories that stem from the personal experience of the traumatic events.
Derivation of the Thematic Material and Intervallic Gestures From the Main Theme in Fantasia Carioca By Sérgio Assad
The quantity of classical guitar literature reached a new peak late in the twentieth century with many famous guitarists publishing their own works for solo classical guitar. This increase in the published guitar literature resulted in a decline of the relative analytical discussions of contemporary guitar works. Sérgio Assad is a perfect example of an active guitarist/composer whose works are frequently performed in guitar recitals and yet very little discussion has been provided attempting to gain a deeper understanding of his compositional language. The purpose of this study is to two-fold: first, to show that Fantasia Carioca (1994) is a very carefully organized work and includes an intricate network of thematic material developed through a spectrum of intervallic gestures, of which all derive from the main theme of the piece; second, to provide a deeper insight into the compositional language of Sérgio Assad through a demonstration of different compositional procedures to which the composer resorts. This one-movement piece reveals a high level of organization present in Sérgio Assad's style. The entire thematic material is carefully derived from the main theme. Each thematic unit shows a set of predetermined characteristics that allow these units to react to particular textures and situations. The thematic organization is interwoven with important intervallic gestures and relationships, which lead the development of the thematic material. The insight into the applied techniques and structural elements provides a highly beneficial pool of information for anybody who decides to perform this piece. The offered arguments also serve as a good starting point for further analytical approaches and examinations of the growing oeuvre of Assad's classical guitar music.
No-thought Shopping: Understanding and Controlling Nonconscious Processing in Marketing
This dissertation explores how nonconscious thought processing might be affected and activated in ways that influence consumer decision making. To activate nonconscious thought processes, this dissertation relies on priming—the unobtrusive activation of mental representations by stimuli in a social context, which occurs without participants' conscious awareness. Three dimensions of consumer decision making are investigated: purchase intention, product evaluation and arousal. The dissertation is based on the auto-motive model of nonconscious goal pursuit and somatic marker hypothesis. The dissertation is driven by three experiments, which respectively explore crucial areas in priming effects and addresses the following research question: can primes be shaped or controlled by marketers? Specifically, the dissertation examines whether shopping behavior can be primed. Second, the dissertation also examines how facial primes displaying basic emotions (happiness, anger, contempt, disgust, fear, sadness, and surprise) can prime emotion and arousal. Finally the dissertation examines the effect of the interaction of the buying prime with the primes of faces displaying basic emotions on the dependent variables of purchase intention, product evaluation, emotion, and arousal. Results from three experimental studies show that shopping behavior can be primed, and primed participants will exhibit higher product evaluation than those exposed to a control prime. Second while exposing participants to primes of faces displaying emotions did not elicit those emotions, the priming with faces did reveal a marginal activation of arousal in the participants. Third priming with faces was not found to interact with primed buying behavior such that the interaction would affect the level of arousal. The results indicate that Bargh's auto-motive model of nonconscious goal pursuit can be applied to marketing. Thus priming shopping behavior can affect product evaluation though the effect of this prime appears to be too weak to be applied in the field. Priming with faces was found not to interact with primed shopping behavior and thus affect product evaluation. The impact of the findings on marketing practitioners suggests that more laboratory investigation is necessary. Further laboratory investigation should be used to raise the effect level of the prime and to find ways to shape and control nonconscious goal pursuit prior to attempting to bring priming into the field.
This Isn't About Me: Communication Privacy Management Theory and Public Confession
Individuals at the DFW Church publicly confess intensely personal information, such as drug and alcohol addiction, spousal and child abuse, stripping, and sexual abuse. Using communication privacy management theory (CPM), I examined the way individuals at the DFW Church manage their private information, how they make disclosure decisions, and how they manage boundaries around their private information. I interviewed 13 individuals who participated in public confession, and coded their responses to identify the common themes and tactics for making disclosure decisions. Through this process, I pioneer the application of CPM to examine public disclosure events, rather than dyadic or small group disclosures. I also expand our current understanding of motivations for disclosure; rather than focusing on selfish or therapeutic motivations, participants want to encourage others through their disclosure. In terms of boundary management, individuals at the DFW Church believe that God owns part, or all, of their information; thus, disclosing their pasts is "not about them." Participants construct a new identity through their testimony narrative, effectively putting the old person in the past and presenting a new, Christian identity to the church body for group approval. In this context, confessing a negative behavior becomes a way to build a positive image by showing the drastic reformation that has taken place in that person's life. Lastly, I propose the public disclosure model—which involves boundary testing, audience analysis, and choice of disclosure path—to be tested for use in future research.
Effects of a Brain Improvement Program on Students' Reading Achievement
How to close the reading achievement gap among K-12 students is an ongoing emphasis for educators in the 21st century. The purpose of the study was to determine if using kinesthetic movements from the Brain Gym® program improved the reading achievement of Grade 3 Hispanic and African American students. Students from four elementary schools participated in the study. The students in the control and experimental groups completed a 2004 release TAKS third grade reading assessment for the pretest and posttest. Students in the experimental group completed five selected kinesthetic movements from the Brain Gym® program five minutes at the beginning of each Monday through Friday school day. The intervention lasted 30 days and a total of 150 minutes. Data were analyzed using a 2 x 2 mixed between-within subjects analysis of variance. Findings revealed that performing the five kinesthetic movements from the Brain Gym® program did not increase students' reading achievement scores. Only the variable of time between pretest and posttest affected students' reading scores. The results from this study did not support the findings of other studies of the effectiveness of kinesthetic movements.
Characterization of Arthrobacter Globiformis Aspartate Transcarbamylase Concentrations of Substrates
This thesis consists of one major section with two subsections. The first subsection investigates the activity of Arthrobacter globiformis aspartate transcarbamylase's specific activity with increasing concentrations of the enzyme's substrate. Dihydroorotase (DHOase) activity was also measured with increasing concentrations of the substrate dihydroorotate. The second subsection collected data in order to classify the enzyme, resulting in a classification into the category of class A ATCases with bifunctional ATCase-DHOase complexes. The thesis provides evidence to broaden understanding of the ATCase and DHOase enzymes for members of the family that Arthrobacter belongs to.
Miranda Reasoning and Competent Waiver Decisions: Are Models of Legal Decision Making Applicable?
Miranda understanding, appreciation, and reasoning abilities are essential to courts' determinations of knowing and intelligent Miranda rights waivers. Despite the remarkable development of Miranda research in recent decades, studies have generally focused on understanding and appreciation of Miranda rights, but have not examined Miranda reasoning and waiver decisions. Therefore, examining the nature of defendants' decisional capacities constitutes a critical step in further developing theoretical and clinical models for competent Miranda waiver decisions. The current study evaluated Miranda waiver decisions for 80 pretrial defendants from two Tulsa-area Oklahoma jails. Previously untested, the current study examined systematically how rational decision abilities affect defendants' personal waiver decisions. Components from general models of legal decision making, such as decisional competence and judgment models, were examined to determine their applicability to Miranda waiver decisions.
Real Analyticity of Hausdorff Dimension of Disconnected Julia Sets of Cubic Parabolic Polynomials
Consider a family of cubic parabolic polynomials given by for non-zero complex parameters such that for each the polynomial is a parabolic polynomial, that is, the polynomial has a parabolic fixed point and the Julia set of , denoted by , does not contain any critical points of . We also assumed that for each , one finite critical point of the polynomial escapes to the super-attracting fixed point infinity. So, the Julia sets are disconnected. The concern about the family is that the members of this family are generally not even bi-Lipschitz conjugate on their Julia sets. We have proved that the parameter set is open and contains a deleted neighborhood of the origin 0. Our main result is that the Hausdorff dimension function defined by is real analytic. To prove this we have constructed a holomorphic family of holomorphic parabolic graph directed Markov systems whose limit sets coincide with the Julia sets of polynomials up to a countable set, and hence have the same Hausdorff dimension. Then we associate to this holomorphic family of holomorphic parabolic graph directed Markov systems an analytic family, call it , of conformal graph directed Markov systems with infinite number of edges in order to reduce the problem of real analyticity of Hausdorff dimension for the given family of polynomials to prove the corresponding statement for the family .
British Labour Government Policy in Iraq, 1945-1950
Britain during the Labour government's administration took a major step toward developing Iraq primarily due to the decision of Ernest Bevin, the Foreign Minister, to start a new British policy toward the Iraqi regimes that would increase the British influence in the area. This led to Bevin's strategy of depending on guiding the Iraqi regime to make economic and political reforms that would lead to social justice.
Pilot of a Learning Management System to Enhance Counselors' Relational Qualities Through Mindfulness-based Practices
Mindfulness-based practices are associated with increased attentional qualities, improved self-focus styles, enhanced empathic understanding, and strengthened self-compassion, making these practices a viable addition to counselor training programs. However, current mindfulness training models are primarily designed for relief of psychological distress, stress reduction, and increased well-being rather than focused on enhancing therapeutic skills and require intensive time commitments that may present logistical difficulties for overburdened curricula and graduate students. This study piloted an on-line, eight-week mindfulness-based practices learning management system for counselors (MBLMS-C) with a specific focus on the cultivation of qualities associated with successful therapeutic relationships. Ten of forty-six recruited counseling master's students enrolled in their first basic skills course at a sample of accredited universities across the United States completed the exit survey. Data were analyzed using multivariate repeated measures analyses comparing pre- post- counselor relational qualities of mindfulness traits, empathy, self-focus style, and self-compassion. Results indicated no statistically significant difference with a partial ?2 = .73. What-if analyses (N = 30) indicated statistical significance may have been obtained given a larger sample. Variance was explained by increased self-compassion (partial ?2 = .34) and mindfulness traits (partial ?2 = .31) and decreased self-focus style rumination (partial ?2 = .23) and empathic personal distress (partial ?2 = .12). Changes were observed in the desired direction for self-focus style reflection and empathic perspective taking/empathic concern. Discussion includes a review of the findings including examination of participant feedback regarding training experience. Study limitations and implications for counselor education, professional enhancement, and suggestions for future research are also offered.
How Drawing Becomes Writing: Proto-orthography in the Codex Borbonicus
The scholarship on the extent of the Nahuatl writing system makes something of a sense-reference error. There are a number of occurrences in which the symbols encode a verb, three in the present tense and one in the past tense. The context of the use of calendar systems and written language in the Aztec empire is roughly described. I suggest that a new typology for is needed in order to fully account for Mesoamerican writing systems and to put to rest the idea that alphabetic orthographies are superior to other full systems. I cite neurolinguistic articles in support of this argument and suggest an evolutionary typology based on Gould's theory of Exaptation paired with the typology outlined by Justeson in his "Origins of Mesoamerican Writing" article.
The Influence of Perceived Support From Parental and Peer Relationships on Students' Health-related Beliefs and Behaviors
College is an important time for young adults, but most college students fail to meet the daily recommendations for physical activity. Social support is associated with positive health practices, but limited research is available on the role of perceived support from specific relationships, (e.g., peers and parents). The purpose of this study was to evaluate the effect of perceived support from parental and peer relationships on health-related beliefs and behaviors. Participants (N = 333) completed the Quality of Relationships Inventory, Multidimensional Scale of Perceived Social Support, Satisfaction With Life scale, and a short version of the Physical Self-Description Questionnaire. While highly active students did not necessarily have more socially support relationships, females self-reported more conflict with both parents and more depth and support with a special person in their life than males, and parental and peer relationships appeared to be a greater influence on females' perceptions of satisfaction and self-worth.
Optical Transparent Pmma Composite Reinforced By Coaxial Electrospun Pan Hollow Nanofibers
Electrospinning has been recognized as an efficient technique for the fabrication of polymer fibers. These electrospun fibers have many applications across a broad range of industries. In this research, optical transparent composites were successfully fabricated by embedding polyacrylonitrile (PAN) hollow nanofibers into poly (methyl methacrylate) (PMMA) matrix. The hollow PAN nanofibers were prepared by coaxial electrospinning. The PAN was used as the shell solution, and the mineral oil was used as the core solution. The resulting fibers were then etched with octane to remove the mineral oil from the core. The hollow PAN fibers were then homogeneously distributed in PMMA resins to fabricate the composite. The morphology, transmittance and mechanical properties of the PAN/PMMA composite were then characterized with an ESEM, TEM, tensile testing machine, UV-vis spectrometer and KD2 Pro Decagon device. The results indicated that the hollow nanofibers have relatively uniform size with one-dimensional texture at the walls. The embedded PAN hollow nanofibers significantly enhanced the tensile stress and the Young's modulus of the composite (increased by 58.3% and 50.4%, respectively), while having little influence on the light transmittance of the composite. The KD2 Pro device indicated that the thermal conductivity of the PMMA was marginally greater than the PAN/PMMA composite by 2%. This novel transparent composite could be used for transparent armor protection, window panes in vehicles and buildings, and airplane windshield etc.
Kinetics of Sulfur: Experimental Study of the Reaction of Atomic Sulfur with Acetylene and Theoretical Study of the Cn + So Potential Energy Surface
The kinetics of the reaction of atomic sulfur with acetylene (S (3P) + C2H2) were investigated experimentally via the flash photolysis resonance fluorescence method, and the theoretical potential energy surface for the reaction CN + SO was modeled via the density functional and configuration interaction computational methods. Sulfur is of interest in modern chemistry due to its relevance in combustion and atmospheric chemistry, in the Claus process, in soot and diamond-film formation and in astrochemistry. Experimental conditions ranged from 295 – 1015 K and 10 – 400 Torr of argon. Pressure-dependence was shown at all experimental temperatures. The room temperature high-pressure limit second order rate constant was (2.10 ± 0.08) × 10-13 cm3 molecule-1 s-1. The Arrhenius plot of the high-pressure limit rate constants gave an Ea of (11.34 ± 0.03) kJ mol-1 and a pre-exponential factor of (2.14 ± 0.19) × 10-11 cm3 molecule-1 s-1. S (3P) + C2H2 is likely an adduct forming reaction due to pressure-dependence (also supported by a statistical mechanics analysis) which involves intersystem crossing. The potential energy surface for CN + SO was calculated at the B3LYP/6-311G(d) level and refined at the QCISD/6-311G(d) level. The PES was compared to that of the analogous reaction CN + O2. Notable energetically favorable products are NCS + O, CO + NS, and CS + NO. The completed PES will ultimately be modeled at the CCSD(T) level (extrapolated to infinite basis set limit) for theoretical reaction rate analysis (RRKM).
Effects of Problem-based Learning on a Fifth Grade Language Arts Classroom
The main purpose of this qualitative research was to discover the effects of problem-based learning on a fifth grade language arts classroom. The secondary purpose was to examine how receptive fifth grade students were to a new way of learning. In this descriptive study, a group of nine students created an alternate reality game as part of a problem-based learning module. The instructional design of the study included three weeks for students to design and construct their games and one week to play, receive feedback and revise based on feedback. Through reflective blogs, semi-structured interviews, video recordings, and observations, data was collected to analyze. Over a period of five months, the data was coded and arranged into categories. The categories merged into themes. The results and findings revealed the impact collaborative groups have on design and enjoyment. Self-regulation skills were found to be lacking in most of the students, intrinsic motivation increased for some students while others developed positive outcomes beyond the scope of this study.
Solid Lubrication Mechanisms in Laser Deposited Nickel-titanium-carbon Metal Matrix Composites
A Ni/TiC/C metal matrix composite (MMC) has been processed using the laser engineered net shaping (LENS) process from commercially available powders with a Ni-3Ti-20C (atomic %) composition. This processing route produces the in-situ formation of homogeneously distributed eutectic and primary titanium carbide and graphite precipitates throughout the Ni matrix. The composite exhibits promising tribological properties when tested in dry sliding conditions with a low steady state coefficient of friction (CoF) of ~0.1 and lower wear rates in comparison to LENS deposited pure Ni. The as deposited and tribologically worn composite has been characterized using Auger electron spectroscopy, scanning electron microscopy (SEM), X-ray diffraction, high resolution transmission electron microscopy (HRTEM) with energy dispersive spectroscopy (EDS), dual beam focused ion beam SEM (FIB/SEM) serial sectioning and Vickers micro-hardness testing. The evolution of subsurface stress states and precipitate motion during repeated sliding contact has been investigated using finite element analysis (FEA). The results of FIB/SEM serial sectioning, HRTEM, and Auger electron spectroscopy in conjunction with FEA simulations reveal that the improved tribological behavior is due to the in-situ formation of a low interfacial shear strength amorphous carbon tribofilm that is extruded to the surface via refined Ni grain boundaries.
Development of a Laponite Pluronic Composite for Foaming Applications
The focus of the following research was to provide an optimized particle stabilized foam of Laponite and Pluronic L62 in water by understanding (1) the Laponite-Pluronic interactions and properties for improved performance in a particle stabilized foam and (2) the interfacial properties between air and the Laponite-Pluronic complex. These studies were conducted using both bulk and interfacial rheology, XRD, sessile droplet, TGA and UV-vis. Two novel and simple techniques, lamella break point and capillary breakup extensional rheometry, were used to both understand the Laponite Pluronic L62 interaction and determine a different mechanism for foaming properties. Bulk rheological properties identified an optimal Laponite concentration of 2% with Pluronic L62 ranging from 2.5% and 6.5%, due to the ease of flow for the dispersion. The Pluronic L62 was observed to enhance the Laponite bulk rheological properties in solution. Additionally TGA showed a similar trend in thermal resistance to water with both addition of Laponite and Pluronic L62. XRD demonstrated that 0.25% Pluronic intercalated into Laponite from dried 2% Laponite films. XRD demonstrated that the Laponite matrix was saturated at 1% Pluronic L62. UV-vis demonstrated that a monolayer of Pluronic L62 is observed up to 0.65% Pluronic L62 onto Laponite. Interfacial rheology showed that Laponite enhances Pluronic L62 at the air-liquid interface by improving the storage modulus as low at 0.65% Pluronic L62 with 2% Laponite. The lamella breakpoint of Laponite with Pluronic films indicate strong film interaction due to higher increases in mass. Extensional rheology indicates that 2.5% to 6.5% Pluronic with 2% Laponite show the most filament resistance to stretching.
Leader Developmental Readiness of Generation Y in the Training Industry
Members of Generation Y in the training and development industry will be required to assume leadership roles as Baby Boomers retire, yet little empirical research exists regarding how best to prepare them for leadership. The purpose of this study was to examine differences in leader developmental readiness between generational cohorts in the training industry, specifically Baby Boomers, Generation X, and Generation Y. Leader developmental readiness provided a definition of developmental readiness for leaders using the five constructs (learning goal orientation, developmental efficacy, self-awareness, leader complexity, and metacognitive ability). A volunteer sample was compiled from members of the ASTD National LinkedIN group (n = 636). Results were analyzed using structured means analysis with maximum likelihood (ML) estimation. Generational cohorts demonstrated differences in leader developmental readiness. Baby Boomers indicated statistically and practically higher metacognitive ability and developmental efficacy than Generation Y. Results demonstrated statistically and practically higher leader complexity in Generation Y and both Generation X and Baby Boomers. These results should inform leader development practitioners as they continue to use existing methods in preparing the different generations for leader development interventions while pointing to possible needs to increase the metacognitive ability and developmental efficacy in Generation Y and ensure accurate perception of leader complexity in those individuals. Further research would be helpful to confirm or refute findings and expand on the target population for enhanced generalizability.
Predictors of Quality of Life (Qol): Comparing Baby Boomers, Older Adults, and Younger Adults Using Data From the 2010 National Health Interview Survey
The purpose of this study was to identify factors that predict quality of life (QOL) for aging adults and to examine and compare Baby Boomers', Older Adults' and Younger Adults' responses to the 2010 National Health Interview Survey/QOL Functioning and Disability. Significant findings included several significant values based on the multivariate regression to estimate a model to predict QOL. In particular, being male, four ethnicities other than white, being older than Boomer, age in 10 years, the Functional Difficulty Index, the Functional Limitation Index scores, chronic heart disease, asthma, and arthritis all had significant p values. Adults with chronic heart disease, asthma, or arthritis scored lower on the QOL index, but cancer, stroke, or diabetes were not associated with the QOL index. Two hypotheses had strong support. Lower scores on both the Functional Difficulty Index and the Functional Limitation Index yielded lower QOL scores. Further research recommendations include establishing reliability and validity of the QOL index; running additional regressions for demographics (ethnicity, marital status, etc.) to predict possible combinations of variables predicting QOL or barriers to QOL; and investigating the viability of incorporating the QOL index into an electronic medical record (EMR) dashboard parameter to serve as a screening mechanism for those aging adults most at risk for chronicities or co-morbidities that place them at risk for losing their ability to age in place in the home of their choosing.
Extrapolating Subjectivity Research to Other Languages
Socrates articulated it best, "Speak, so I may see you." Indeed, language represents an invisible probe into the mind. It is the medium through which we express our deepest thoughts, our aspirations, our views, our feelings, our inner reality. From the beginning of artificial intelligence, researchers have sought to impart human like understanding to machines. As much of our language represents a form of self expression, capturing thoughts, beliefs, evaluations, opinions, and emotions which are not available for scrutiny by an outside observer, in the field of natural language, research involving these aspects has crystallized under the name of subjectivity and sentiment analysis. While subjectivity classification labels text as either subjective or objective, sentiment classification further divides subjective text into either positive, negative or neutral. In this thesis, I investigate techniques of generating tools and resources for subjectivity analysis that do not rely on an existing natural language processing infrastructure in a given language. This constraint is motivated by the fact that the vast majority of human languages are scarce from an electronic point of view: they lack basic tools such as part-of-speech taggers, parsers, or basic resources such as electronic text, annotated corpora or lexica. This severely limits the implementation of techniques on par with those developed for English, and by applying methods that are lighter in the usage of text processing infrastructure, we are able to conduct multilingual subjectivity research in these languages as well. Since my aim is also to minimize the amount of manual work required to develop lexica or corpora in these languages, the techniques proposed employ a lever approach, where English often acts as the donor language (the fulcrum in a lever) and allows through a relatively minimal amount of effort to establish preliminary subjectivity research in a target language.
Evaluating Appropriateness of Emg and Flex Sensors for Classifying Hand Gestures
Hand and arm gestures are a great way of communication when you don't want to be heard, quieter and often more reliable than whispering into a radio mike. In recent years hand gesture identification became a major active area of research due its use in various applications. The objective of my work is to develop an integrated sensor system, which will enable tactical squads and SWAT teams to communicate when there is absence of a Line of Sight or in the presence of any obstacles. The gesture set involved in this work is the standardized hand signals for close range engagement operations used by military and SWAT teams. The gesture sets involved in this work are broadly divided into finger movements and arm movements. The core components of the integrated sensor system are: Surface EMG sensors, Flex sensors and accelerometers. Surface EMG is the electrical activity produced by muscle contractions and measured by sensors directly attached to the skin. Bend Sensors use a piezo resistive material to detect the bend. The sensor output is determined by both the angle between the ends of the sensor as well as the flex radius. Accelerometers sense the dynamic acceleration and inclination in 3 directions simultaneously. EMG sensors are placed on the upper and lower forearm and assist in the classification of the finger and wrist movements. Bend sensors are mounted on a glove that is worn on the hand. The sensors are located over the first knuckle of each figure and can determine if the finger is bent or not. An accelerometer is attached to the glove at the base of the wrist and determines the speed and direction of the arm movement. Classification algorithm SVM is used to classify the gestures.
The Disney Influence on Kindergarten Girls' Body Image
Media is now a part of the early childhood world. In many countries, including industrialized and developing countries, children spend more time consuming various kinds of media. The impact of media on children's perception of their body images has been and continues to be a concern of parents and early childhood professionals. This research examined the influence of Disney movies on Thai kindergarten girls' body images and self-esteem. Thai kindergarten girls completed three measures of body self-image: the Body Figure Preference Scale, the Body Esteem Scale, and the Self-Esteem Scale. The girl participants were randomly assigned to two groups: focused on a female theme (FFT) and focused on a non-human theme (FNT). The experimental group viewed "female" Disney movie themes, while the control group viewed "animal" Disney movie themes. Girls in the experimental group expressed greater body image dissatisfaction scores after watching Disney movies, which was an expected finding. Results from the present study suggest that girls in both groups become concerned about their body esteem after video exposure. However, there was no significant difference in self-esteem between girls in FFT and FNT. In summary, the findings of this study support the belief that Disney movies influence young girls' perceptions of their body image, and they have an awareness of their body size. It can be concluded that Disney movies have an influence on Thai girls' body image dissatisfaction and body esteem. The results also indicated that Thai girls are not totally aware of the influence of Disney media on their self-esteem. Understanding how Disney movies, in particular, and other media, in general, influence young children, especially girls, can encourage parents and educators to identify risk factors associated with children's body image dissatisfaction and low self-esteem.
Attention Biases Associated with Vulnerability to Bipolar Disorder
Bipolar disorder is associated with significant social and occupational impairments, as well as increased risk for substance abuse and suicide. More research is needed to identify potential mechanisms associated with vulnerability to the disorder. Previous research has identified altered processing of emotional information in bipolar and bipolar-prone individuals, including attentional biases which appear to differ based on the current affective state of the individual. The current study applied a sensitive measure of attention (i.e., eye-tracking) to assess whether vulnerability to bipolar disorder, as indexed by hypomanic personality traits, would be correlated with biases in attention to emotional facial stimuli, independent of mood state. Hypomanic personality traits were hypothesized to be associated with greater attention to happy and angry faces, as indexed by faster initial orientation, more frequent gazes, and longer gaze duration for these stimuli. Participants completed self-report measures assessing current mood symptoms, positive and negative affect, and hypomanic personality traits. They then completed two tasks assessing attention for emotional faces. The first was an eye-tracking task, which measured latency to first fixation, total gaze duration and total number of gazes for each emotional face category. The second was a spatial cueing task which assessed both attentional engagement with emotional faces, and ability to disengage attention from this material. Hypomanic personality traits were significantly negatively correlated with latency to orient attention to happy faces. A trend toward decreased latency to orient to angry faces with higher hypomanic personality traits was also demonstrated. Hypomanic traits were not correlated with attention to sad faces. Furthermore, hypomanic traits were associated only with differences in initial orientation of attention, not with continued engagement or disengagement. The results of this study suggest that individuals with higher levels of hypomanic personality traits, who are hypothesized to be at greater risk of developing bipolar disorder, are characterized by differences in their initial orientation of attention to positive emotional stimuli, independent of their current mood state. This finding is indicative of biased information processing in individuals with vulnerability to bipolar disorder. Such a bias may have important clinical implications for individuals with a vulnerability to bipolar disorder, as it may represent a mechanism by which vulnerability leads to increased, and at times problematic, engagement with rewarding stimuli.
La Evolución Del Subalterno En Tres Novelas Mexicanas: La Negra Angustias, Balún Canán, Y Neonao
The subaltern is a recurrent literary figure in Mexican narrative. The objective of this thesis is to investigate three ethnic groups – indeed, subalterns – in Mexico which include: Afro-Mexicans, indigenous groups, and Filipino colonial subjects from the perspectives of the Mexican Revolution, post-revolutionary Mexico, and the conquest of the Philippines in the sixteenth century. The principal characters play crucial roles in events shaping the history and culture of Mexico and thus demonstrate their importance to the country's development while also revealing the reality of subalterns. The literary research shows that trying circumstances or a lack of self-identity were the main causes for a character to be or become a subaltern in addition to their inherent ethnic disadvantages. However, the characters who overcame their subaltern state often changed personality traits or adapted to their surroundings in order to be assimilated into the majority culture.
Ethnic Politics in New States: Russian and Serbian Minorities After Secession
New states are often born in a volatile environment, in which the survival of the new country is uncertain. While analysis of the nationalizing new governments exists, research focuses mainly on domestic politics. I argue that the treatment of minority that remains in the new states is a function of the interaction of the dual threat posed by the minority itself domestically on one hand and the international threat coming from the mother state to protect its kin abroad on the other hand. Specifically, I argue that there is a curvilinear relationship between domestic and international threat and the extent of discrimination against the politically relevant minority. Most discrimination takes place when domestic and international threats are moderate because in this case there is a balance of power between the government, the minority, and the rump state. With time-series-cross-sectional (TSCS) data analysis this dissertation systematically tests the treatment of Russian and Serbian minorities in all post-Soviet and post-Yugoslav states between 1991 and 2006 and finds statistically significant results for the curvilinear hypothesis. Territorial concentration of the minority and the ratio of national capabilities between the mother and the seceded states prove to be especially important predictors of minority treatment. In addition, with most similar systems (MSS), most different systems (MDS) design methods, and directed case studies I apply the curvilinear hypothesis to the Russian minority in the Baltic States and the Central Asian Republics, and also to the Serb minority in the countries of the former Yugoslavia to present a detailed analysis.
Exploring Psychopathic Personality Traits and Moral Development in a Non-criminal Sample
This study explored psychopathic personality traits among a non-criminal, college undergraduate sample. Much research has been done on conceptualizing the construct of psychopathy, but this work has been conducted primarily with incarcerated individuals using a structured interview, The Psychopathy Checklist – Revised (PCL-R; Hare, 1991, 2003). The goal of the current study was to assess psychopathic traits among non-criminal individuals using The Self-Report Psychopathy Scale - Version Four (SRP-IV; Paulhus, Neumann, & Hare, in press), and compare how SRP-IV scores were associated with a well recognized semi-structured interview for psychopathy, The Psychopathy Checklist – Screening Version (PCL: SV; Hart, Cox, & Hare, 1995). The study also examined whether psychopathic personality traits could be predicted using a measure of normal-range personality, based on the five-factor model (FFM; Digman, 1990), and a measure developed by Loevinger (1976) related to ego development. Five-Factor Model Rating Form (FFMRF; Mullins-Sweat, Jamerson, Samuel, Olson, & Widiger, 2006) scores and Total Protocol Ratings (TPR score) on the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) were used to predict psychopathy scores. Correlations of SRP-IV scores and PCL: SV scores with FFMRF scores and WUSCT TPR scores were also examined for their uniformity. As predicted, there were significant, negative correlations between FFM domains, Agreeableness and Conscientious, and SRP-IV scores, as well as significant, negative correlations between WUSCT TPR scores and SRP-IV scores. These correlations ranged from small to strong for both SRP-IV overall scores and for SRP-IV factor scores (i.e., Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Criminal Tendencies). Additionally, FFM domain scores and WUSCT TPR scores significantly predicted SRP-IV scores. FFM domains, Agreeableness and Conscientiousness, and WUSCT TPR scores, were the strongest predictors of SRP-IV scores. Similar results were found when FFM domain scores and WUSCT TPR scores predicted SRP-IV factor scores. Results also indicated Agreeableness and Conscientious explained an additional 24% of the variance in psychopathy scores, after controlling for WUSCT TPR scores. Conversely, WUSCT TPR scores explained an additional 5% of the variance in psychopathy scores after controlling for Agreeableness and Conscientiousness. Finally, as predicted, the differences in correlations between psychopathy scores (i.e., PCL: SV, SRP-IV), and Agreeableness, Conscientiousness, and WUSCT TPR scores were not statistically significant providing evidence that correlates of psychopathic traits can be measured among non-criminal individuals using a self-report measure, the SRP-IV, and that these findings are concordant with those based on a standardized structured assessment for psychopathy. Limitations of the study, implications, and recommendations for future research are also discussed.
Ecological Forms of Life: Wittgenstein and Ecolinguistics
The present philosophical literature on philosopher Ludwig Wittgenstein tends to either stagnate by focusing upon issues particular to Wittgenstein's philosophy or expand the boundaries of Wittgenstein's thought to shed light onto other areas of study. One area that has largely been ignored is the realm of environmental philosophy. I prepare the way for a solution to this by first arguing that Wittgenstein's later philosophy of language shows 'proto-ecolinguistic' concerns, sharing much in common with the ecolinguistic thought of both Peter Mühlhäusler and Luisa Maffi. This reading, as well as the work of Mühlhäusler and Maffi, is a starting point for an opposition to a common trend in much of contemporary linguistics of adhering to a linguistic paradigm of universalizing linguistic atomism that gives an impoverished account of language. This impoverished account is argued to have potential environmental and ecological consequences which the universalizing atomistic paradigm is ill-equipped to address.
Down, Set, Like? A Study of Social Networking and Sports Fandom
Sports in the 21st century have become popular across multiple industries, and a major boon to a television industry dealing with increasing audience fragmentation. So an understanding of fans' behavior is important to all parties. This study, an online survey consisting of 242 responses, examined fandom and its relationship with time spent using social networking sites and found no statistical correlation. Six uses and gratification factors obtained: human connection, network content, distraction/amusement, social integration, social surveillance, and active entertainment. The low comparative saliency of the social integration factor suggests that perhaps fandom is distinct from other ways of identifying with similarly-minded individuals (e.g. political and/or religious affiliation), or that perhaps fandom as a factor is less than sufficient to explain how/why sports fans use social networking sites.
