Examining the Effect of Security Environment on U.S. Unilateral Military Intervention in Civil Conflicts
This study focuses on how perceived security environment affect U.S. unilateral, military intervention in civil conflicts, using the concept of Bayesian learning to illustrate how threat perceptions are formed, how they change, and how they affect the U.S. decision to intervene militarily in civil conflicts. I assess the validity of two primary hypotheses: (1) the U.S. is more likely to intervene in civil conflicts with connections to a threatening actor or ideology; and (2) the U.S. is more likely to intervene in civil conflicts for humanitarian motives in a less threatening security context. To test these hypotheses, I compare U.S. military intervention in three temporal contexts reflecting more threatening security contexts (Cold War and post-9/11) and less threatening security contexts (1992-2001). Results of logit regression analysis reveal that a conflict’s connection to a threatening actor or ideology is the most statistically and substantively significant determinant of U.S. military intervention in civil conflicts, both in more and less threatening security contexts. They also indicate that humanitarian motives are not a statistically significant determinant of U.S. military intervention in civil conflicts, even in a more benign security environment. These findings imply that U.S. unilateral military intervention is reserved for more direct national security threats, even those that are less grave, and that the perception of the U.S. as “global cop” may be misleading, at least in terms of unilateral military intervention.
Examining the Effects of Apparel Attributes on Perceived Copyright Infringement and the Relationship Between Perceived Risks and Purchase Intention of Knockoff Fashion
The growth of fast fashion retailers, availability of knockoff fashion apparel, and proposed apparel copyright law prompted this study. Fast fashion retailers are expanding rapidly and producing knockoffs fashion apparel in a matter of weeks, but current U.S. copyright laws do not protect apparel. The primary purpose of this study was to identify prominent visual fashion apparel attributes that could determine perceived copyright infringement. A secondary purpose was to examine the effects of fashion apparel attributes on perceived copyright infringement, perceived risk, and purchase intention. A sequential exploratory mixed method approach was used to explore the relationship between: Attributes, perceived copyright infringement, perceived risk, and purchase intention. This study consisted of a: Study one, study two, and study three. Twelve hypotheses were proposed, and five were supported. Quality significantly affected both perceived copyright infringement and purchase intention. Performance, social, and asset significantly affected purchase intention of knockoff fashion apparel.
Examining the Effects of Psychographics, Demographics, and Geographics on Time-Related Shopping Behaviors
The purpose of this study was to determine the effects of psychographic (shopping orientation, lifestyle, social class), demographic (gender, ethnicity, age), and geographic (area of residence) variables on time-related shopping behaviors when shopping for clothing for the self. The concept of time-related shopping behaviors has not been the focus of any study of the American market. Data (N = 550) were collected via a questionnaire with an online survey company. Through analysis of chi square statistics, ANOVA, Pearson product-moment correlation, and factor analysis, it was found that psychographics and demographics affected time-related and other shopping behaviors. Geographics was found to affect shopping behavior, but not specifically the time-related shopping behaviors studied.
Examining the Engagement of Transfer Students in Texas Universities
The success of transfer students plays a critical role in improving the baccalaureate attainment rates of undergraduates attending 4-year higher education institutions in Texas; however, current indicators suggest transfer students have lower persistence and graduation rates relative to students who begin and complete their college education at one university (i.e., non-transfer students). Additionally, the research literature indicates a link between degree completion and engagement; however, transfer students are reported to be less engaged and less likely to persist than their counterparts. This quantitative study compared the engagement experiences of 2-year transfers, 4-year transfers, swirl transfer, and non-transfers by using National Survey of Student Engagement (NSSE) 2008 data to determine if there are any differences among these groups, and if these differences persist after controlling for individual and institutional covariates. the sample consisted of 2,000 seniors attending 4-year higher education institutions in Texas. the engagement scores of each group were compared using a multivariate analysis (MANOVA). This study found non-transfers were more engaged than each type of transfer student on Student-Faculty Interaction and Supportive Campus Environment factors; moreover, these differences generally persisted after controlling for residence, enrollment status, and institutional control (i.e., public vs. private).The data indicated no difference among the three transfer sub-groups for any of the engagement variables, which suggests their engagement experiences were similar. This research suggests that efforts to increase the participation and success rates of Texans, particularly those described as transfers, may be informed by how students perceive their engagement experiences; consequently, institutions may consider modifying and implementing policies that promote student participation in educationally purposeful activities leading to persistence and graduation.
Examining the Impact of Community Policing on Public Attitudes toward Fear of Terrorism, Resilience, and Satisfaction with Police in the Face of New Terrorism
This dissertation examines the impact of citizen's perception of community policing on public attitudes toward fear of terrorism, resilience for a future terrorist attack, and satisfaction with the police in the face of new terrorism. In particular, considering the changing nature of terrorism in recent years as a response to the centralized homeland security efforts, this dissertation attempts to develop our understanding about the extent to which community policing could be a strategy in dealing with terrorism fear among citizens, in building up resilience for future terrorist attacks, and to increase citizens' satisfaction with the police in order to enhance the quality of life in the face of new terrorism. Additionally, this dissertation examines the impact of the variation in the level of community policing implementation on public attitudes toward fear of terrorism, resilience for a future terrorist attack, and satisfaction with the police. Data was collected through an online survey conducted in the cities of Arlington and Frisco, Texas. The survey distributed to the citizens through the Amazon Mechanical Turk (MTurk) platform. These cities were selected based on a community policing scale which was created through the help of the Law Enforcement Management and Administrative Statistics (LEMAS) survey. Results suggest significant association between the citizen's perception of community policing and fear of terrorism, resilience, and satisfaction with the police respectively, highlighting the importance of community policing philosophy as a framework for a comprehensive proactive strategy in response to the existing and ongoing terrorism threat.
Examining the Impact of the Community of Inquiry and Student Learning Process on Participants' Academic Achievement
This dissertation presents an empirical investigation of learning from online courses. The current dissertation examined student participation, using Arbaugh et al.'s Community of Inquiry (CoI) survey instrument and Biggs et al.'s revised version of the Study Process Questionnaire (R-SPQ-2F) to determine CoI influences on learning from the students' perspective. This study is in response to Rourke and Kanuka's call to provide further empirical evidence about CoI conceptual framework connections to deep and meaningful learning. The purpose of this study was to examine the impact of the elements of CoI, cognitive, social, and teaching presences and students' learning approaches to students' perceived learning. Students enrolled in traditional, online, and, blended courses during the 2016 spring semester at a southwestern university participated in a web-based survey. Structural equation modeling was used to test the indirect effects between the elements of CoI, learning approaches, and perceived learning. Student's deep approach to learning was found to have an indirect effect between cognitive presence and perceived learning. However, this study's findings, when the CoI framework was viewed in its entirety, failed to provide evidence to simulate deep and meaningful learning.
Examining the Influence of Visual Culture on a Saudi Arabian Child's Drawings
This study examines the ways visual culture influences a child's drawings. The child is my 9-year-old daughter Nada, who was born in Saudi Arabia and is a fourth-grade student temporarily living in the United States. The study uses qualitative methods of data collection and exploratory case study research design as a methodology. The data were analyzed in light of Althusser's theory of ideology, specifically the notion of interpellation, along with visual culture theories. In addition, gender performativity theory, specifically the work of Judith Butler, was used to consider gender issues when these concerns emerged from the study. Nada has been exposed to two diverse cultures, those of Saudi Arabia and the United States. Both cultures may impact Nada's interpretations of her visual surroundings in various ways. Therefore, recognizing and examining how she interacts with US visual culture might help to uncover how such interactions constitute the basis of her perceptions, identities, and critical thinking. Drawing is not only a means of self-expression but also an important function of communication, identity formation, and represents possible ways of being in the world that are related to culture, community, and society as a whole. The study begins with the premise that there is a gap in understanding between the importance of visual culture and its insufficient application in Saudi Arabian art education. The implications of this study may be informative for Saudi Arabian educators, individuals, or groups interested in visual culture education and children's drawings; potentially, the Saudi Arabian educational system may also use this study to enhance its appreciation of the impact of visual culture on the creation of art and knowledge.
Examining the Origins of Sociology: Continuities and Divergences Between Ibn Khaldun, Giambattista Vico, August Comte, Ludwig Gumplowicz, and Emile Durkheim
This thesis examines the extent to which Ibn Khaldun can legitimately be considered a founding father of sociology. To pursue this research, Khaldun's theoretical framework will be compared with four Western scholars: Auguste Comte, Emile Durkheim, Giambattista Vico, and Ludwig Gumplowicz. This paper begins with an Introduction (Chapter I), followed by a general overview of Khaldun's work (Chapter II). Next, Khaldun's work is compared to that of Auguste Comte (Chapter III), Emile Durkheim (Chapter IV), Ludwig Gumplowicz (Chapter V) and Giambattista Vico (Chapter VI). In each of these chapters, Khaldun is compared and contrasted to the other social theorist, illustrating their similarities and considering their differences. Finally, in Chapter VII, I put forth conclusions that consider the extent to which Khaldun can validly be considered a founding father of sociology.
Examining the "Portfolio Careers" of Classical Musician Entrepreneurs through the Lens of Seven Clarinetists
Many classically-trained clarinetists do not know how to use their performance skills and life experiences to create financially sustainable and artistically fulfilling musical opportunities. Music careers have traditionally included teaching positions in academia and performance positions in professional ensembles. Because of the limited number of jobs in these two areas, clarinetists, and classical musicians in general, often turn to work that provides financial security but may lack artistic fulfillment. The proposed solution to this situation is for musicians to create "portfolio careers," which is defined in this document as a combination of multiple part-time jobs to create full-time work. The purpose of this document was to examine best practices in creating and sustaining a portfolio career through the specific lens of seven clarinetists who have shown themselves to be successful performers and entrepreneurs. Results showed that the best practices include: 1) turn ideas into actions, even if the idea is still in the prototype stage, 2) build and utilize a network of successful and supportive people, 3) say "yes" to opportunities, and 4) find creative work outside the field of music that inspires music-related work.
Examining the Psychological Resiliency of Latino Immigrants in Five Texas Cities: Policy, Economics, and Politics – The Case of the Latino Community
This dissertation examines the impact of city-level characteristics (immigration-friendliness index, unemployment rate, and the percentage of Democrat Party votes) on the psychological resiliency of Latino immigrants. In the light of increased attention on the immigrant issue throughout the world, this study aims to develop our understanding of the factors that have the effect on the resiliency of immigrant populations. This dissertation examines these different characteristics by examining five different cities in Texas: Austin, Dallas, Fort-Worth, Houston, and San Antonio. The survey was distributed through the Amazon Mechanical Turk (MTurk) to those individuals who define themselves Hispanic or Latino. Results suggest that the city characteristics have a significant impact on the resiliency of Latino immigrants suggesting that local governments have a potential capability to increase the resiliency of the immigrant groups in the United States by embracing the notion that immigrants should be integrated into the fabric of the local community.
Examining the Relationship between Bullying Experiences, Parental Partner Violence, and Partner Violence in Young Adulthood
The current study used secondary analysis of existing data to examine associations between bullying experiences, parental partner violence, and partner violence in young adulthood. We hypothesized that bullying in adolescence would be associated with witnessing parental IPV in adolescence and IPV in young adulthood. We believed that deficits in social information processing, particularly hostile attribution biases, would be associated with adolescent bullying. Lastly, we believed that decentering would act as a moderator, affecting the relationship between adolescent bullying and IPV in adulthood. We used correlational and moderation analyses to examine these hypotheses and found that relational bullying victimization was associated with witnessing parental IPV, and the frequency of bullying perpetration was associated with IPV perpetration in adulthood. We found that some aspects of bullying victimization were negatively associated with being unassertive, bullying perpetration was associated with hostile attribution biases, and the relationship between bullying and IPV was significant only at certain levels of decentering maturity.
Examining the Relationship Between Individual and Work Environment Characteristics and Learning Transfer Factors
To impact student learning, educators’ implementation, or transfer, of new knowledge, skills, dispositions, and practices to daily work is the primary purpose of professional learning. The purpose of this study was to assess the multivariate relationship between individual and work environment characteristics as measured by the Collective Efficacy Scale and Dimensions of Learning Organization Questionnaire, respectively, and learning transfer factors as measured by the Learning Transfer System Inventory. The sample consisted of 249 PK-12 grade school- based instructional staff members of an education association. Canonical correlation and commonality analyses required using the two individual and work environment characteristics of learning culture and collective efficacy as predictor variables of the five learning transfer factors of performance self-efficacy, transfer-effort performance expectations, performance outcome expectations, performance coaching, and resistance to change to evaluate the multivariate between the two variable sets. Learning culture and collective efficacy demonstrated a relationship to resistance to change and performance outcome expectations. Learning culture and collective efficacy were insufficient to transfer-effort performance expectations, attend to performance self-efficacy beliefs, and increase support for transfer (i.e., performance coaching) factors. These findings might guide the decisions and practice of individuals with responsibility to plan, implement, and evaluate professional learning, and provide the conditions necessary for changing educational practice while increasing support for and building educators’ confidence about implementation. Further research may confirm the findings and enhance generalizability.
Examining the Relationship Between Persistence in Attendance in an Afterschool Program and an Early Warning Index for Dropout
School districts constantly struggle to find solutions to address the high school dropout problem. Literature supports the need to identify and intervene with these students earlier and in more systemic ways. The purpose of this study was to conduct a longitudinal examination of the relationship between sustained afterschool participation and the host district’s early warning index (EWI) associated with school dropout. Data included 65,341 students participating in an urban school district’s after school program from school years 2000-2001 through 2011-2012. The district serves more than 80,000 students annually. Data represented students in Pre-Kindergarten through Grade 12, and length of participation ranged from 1 through 12 years. Results indicated that student risk increased over time and that persistent participation in afterschool programming had a significant relationship with student individual growth trajectories. Slower growth rates, as evidenced through successive models, supported students being positively impacted by program participation. Additionally, participation was more meaningful if students persisted, as noted in the lower EWI rates, as compared to students who attended less consistently.
Examining the Role of Latitude and Differential Insolation in Asymmetrical Valley Development
Valley development through erosional processes typically tends to create symmetrical valleys. Over time, water cuts through the substrate to create valleys, gorges, and canyons for which the sides are the valley are evenly sloped. However, there are anomalies to this process. Asymmetrical valleys have been well-documented even in areas of uniform substrate or little tectonic uplift. One proposed explanation for the asymmetry of these valleys is differential insolation. This may lead to different microclimates from one slope to another which alter the rate and extent of erosion. Since the differences in received insolation vary with latitude (especially in streams that flow along an east/west axis), it follows that the degree of asymmetry should also vary with latitude if differential insolation is a primary driving factor in the development of these valleys. To evaluate if insolation plays a role in the development of asymmetrical valleys, this study examines variability in asymmetry across 447 valleys in nine study areas located at different latitudes. The degree of asymmetry for each valley was measured by using 30 meter resolution digital elevation models (DEMs) to determine the slope angle of each side of the valley. Asymmetry was measured by computing a ratio of the average slope angle for each side of the valley (larger value divided by smaller). If the resulting value is one, the valley is deemed symmetrical. As the value increases, the degree of asymmetry increases. This investigation found that contrary to expectations, valleys at lower latitudes tend to have a higher degree of asymmetry than those at higher latitudes, which suggests that differential insolation does not play a major role in the development of these valleys. Instead, this study found that high altitudes and low latitudes are more frequently associated with a higher degree of asymmetry. These unexpected findings open the door …
Examining the Shade/flood Tolerance Tradeoff Hypothesis in Bottomland Herbs Through Field Study and Experimentation
While there is growing evidence that shade/flood tolerance tradeoffs may be important in distributions of bottomland hardwood trees and indications that they should apply to herbs, no studies have definitively explored this possibility. Four years of field data following historic flooding were supplemented with a greenhouse experiment designed to identify interactions congruent with tradeoffs. Fifteen bottomland species were grown in two levels of water availability and three levels of shade over 10 weeks. Results indicate responses of Fimbristylis vahlii and Ammannia robusta are consistent with tradeoffs. Modification of classical allometric responses to shade by substrate saturation indicates a potential mechanism for the tradeoff in A. robusta. Responses indicating potential for increased susceptibility to physical flooding disturbance are also discussed.
Examining Visual Art Experiences for Relationship Building in Shared-site Locations
This study explored the perceptions of 74 activity directors responsible for the intergenerational programming that is currently taking place at shared-sites, facilities where older adults and young people receive services and programs simultaneously in a co-located space. Data for this study was collected through a national survey of 149 shared-sites collected from the Generations United data base. the questionnaire asked respondents about their facility’s intergenerational programming, demographic information, and perceived sense of community exhibited by participants in the intergenerational program. Descriptive data regarding the location, primary emphasis, ages and number served, and specific program characteristics, including visual art programming, at IGSS facilities were collected and analyzed. Results from the analysis were reported with limitations. There was a statistical significance suggested in the association of the frequency and duration of art activities with some of the sense of community variables. the study is valuable in determining the current demographics of IGSS facilities that offer visual art programs. Further research needs to be conducted to answer questions regarding the specific role that the visual arts play in creating a sense of community among intergenerational participants at shared-site facilities.
Exceedance Frequency Analysis of Urban Stormwater Quality and Its Relation to Land Use Change, Denton, Texas
Urbanization causes various environmental issues including water pollution, air pollution, and solid waste. Urbanization of watersheds has a profound influence on the quality of stormwater runoff. The quality of stormwater runoff is highly associated with land use. This study analyzed the exceedance frequency of stormwater quality in five watersheds of Denton over eleven years and also analyzed the relationship between stormwater quality and land use/cover of each watershed. The results showed that the most of the water quality parameters that were examined in the Lower Pecan watershed exceeded their threshold most frequently. The higher frequency of exceedance in this watershed can be attributed to the wastewater treatment plant and landfill site. Total suspended solids and turbidity were frequently exceeded in Hickory and Clear Creek watersheds. Conductivity was found to have highest percentage of exceedance in Upper Pecan and Cooper watersheds. Thus, rural watersheds were related with higher exceedance of TSS and turbidity whereas urban watersheds were related with higher exceedance of conductivity.
Exceptional Properties in Friction Stir Processed Beta Titanium Alloys and an Ultra High Strength Steel
The penchant towards development of high performance materials for light weighting engineering systems through various thermomechanical processing routes has been soaring vigorously. Friction stir processing (FSP) - a relatively new thermomechanical processing route had shown an excellent promise towards microstructural modification in many Al and Mg alloy systems. Nevertheless, the expansion of this process to high temperature materials like titanium alloys and steels is restricted by the limited availability of tool materials. Despite it challenges, the current thesis sets a tone for the usage of FSP to tailor the mechanical properties in titanium alloys and steels. FSP was carried out on three near beta titanium alloys, namely Ti6246, Ti185 and Tiβc with increasing β stability index, using various tool rotation rates and at a constant tool traverse speed. Microstructure and mechanical property relationship was studied using experimental techniques such as SEM, TEM, mini tensile testing and synchrotron x-ray diffraction. Two step aging on Ti6246 had resulted in an UTS of 2.2GPa and a specific strength around 500 MPa m3/mg, which is about 40% greater than any commercially available metallic material. Similarly, FSP on an ultra-high strength steel―Eglin steel had resulted in a strength greater than 2GPa with a ductility close to 10% at around 4mm from the top surface of stir zone (SZ). Experimental techniques such as microhardness, mini-tensile testing and SEM were used to correlate the microstructure and properties observed inside SZ and HAZ's of the processed region. A 3D temperature modeling was used to predict the peak temperature and cooling rates during FSP. The exceptional strength ductility combinations inside the SZ is believed to be because of mixed microstructure comprised of various volume fractions of phases such as martensite, bainite and retained austenite.
Excerpts From the Eva Crane Field Diary: Stories
Male or female, young or old, the characters of this collection inhabit a liminal space of trauma and social dislocation in which elements of the real and fabulous coexist in equal measure. The ghosts that populate the stories are as much the ghosts of the living, as they are the ghosts of the dead. They represent individual conscience and an inescapable connection to the past.
Executive Control of Craving: An Examination of College Students
Previous research has shown that alcohol abuse may cause a deficit in frontal lobe functioning, specifically, areas of the frontal lobe that are related to executive function. Additionally, problems with executive function have been related to increased difficulty in managing cravings to addictive substances. The current study explored the relationship between alcohol use and performance on measures of executive functioning in a sample of 121 traditional college students. Students were given 5 measures of executive function designed to explore mental set shifting, updating, inhibition, sustained attention, and planning. These measures were used to examine the relationship between executive function and craving as measured by the Obsessive Compulsive Drinking Scale. Levels of alcohol use were also examined using the Alcohol Use Disorders Identification Test in relation to executive function performance and family history of alcohol abuse.
Executive Information Seeking and the Corporate Library
This study began with an interest in corporate libraries and a genuine curiosity in the information preferences and resources valued by executive leaders at JET Aircraft Co. Executive information preferences and the downward trend in special libraries initiated the investigation of information seeking among executive leaders and yielded the inquiry: What resources do JET Aircraft Co. executives value when they need information? Employing an ethnographic approach, this study investigated what JET Aircraft Co. executives know about information resources, what they believe about information resources, and how they act when they require information. While JET Aircraft Co. maintained a special corporate library called the Company Research Library (CRL), the purpose of this study was to determine what resources were of value to executives at JET Aircraft Co., understanding that the CRL may or may not be a resource executives’ value. As a byproduct, this study also sought to establish executive information preferences and perceptions of the CRL. Information seeking at the executive level, studied through an ethnographic lens, provided insight into how executives at JET Aircraft Co. work and what they prefer, and it established a baseline for the Company Research Library’s position among the resources valued by executives.
Exotic Femininity: Prostitution Reviews and the Sexual Stereotyping of Asian Women
Studies on prostitution have typically focused on the experiences, problems, and histories of prostitutes, rather than examining men who seek to purchase sex. Race has also been overlooked as a central factor in shaping the sex industry and the motivations of men who seek to purchase sex. This study utilizes online reviews of prostitutes to examine the way men who purchase sex discuss Asian prostitutes in comparison to White prostitutes. This paper traces the history of colonialism and ideas of the exotic Orient to modern stereotypes of Asian women. These stereotypes are then used to frame a quantitative and qualitative analysis of online reviews of prostitutes and compare the ways in which Asian prostitutes and white prostitutes are discussed. Further, the reviews are used to examine more broadly what services, traits, and behaviors are considered desirable by men who use prostitutes. The study finds that there are significant quantitative and qualitative differences in how men discuss Asian and White prostitutes within their reviews, and that these differences appear to be shaped by racially fetishizing stereotypes of Asian women. Prostitution also appears to reinforce male dominance and patriarchy in the form of masculine control and the feminine servicing of male sexual and emotional needs.
Expanding the Notion of Campus Climate: the Effect of Religion and Spirituality on the Perception of Campus Climate
Religion/spirituality is a salient facet of identity for many college students, yet addressing issues related to spirituality/religion is contentious in many higher education institutions. Prior research has shown that various other facets of identity, including race/ethnicity, gender, and sexual orientation, affect a student’s perception of campus climate, but religious/spiritual identity has not been examined in the same manner. Using confirmatory factor analysis and structural equation modeling, this study empirically tests the addition of religion/spirituality to the campus climate theory developed by Hurtado et al. (1999). Data came from the 2010 College Senior Survey administered by the Higher Education Research Institute at the University of California, Los Angeles. Results indicate that religious and spiritual identity have significant direct effects on the perception and other aspects of campus climate. Future research is needed to extend the understanding between religious and spiritual identity and the perception of campus climate.
Expanding the Violin's Possibilities in Chinese Music: A Case Study of Transcription and Performance Issues Related to Pipa Music Played on the Violin
In recent years, a large part of the erhu's repertoire has been arranged for performance on the violin and vice versa. Given the difficulties involved in transcribing the music of plucked or woodwind instruments for the violin, the erhu has been the most popular choice for transcribing Chinese music for the violin. However, the erhu and violin are radically dissimilar instruments based on different principles. Pipa music is an essential part of traditional Chinese music from as early as 202 BCE, and the instrument's repertoire represents a large portion of East Asian music aesthetics, and this context should be considered to successfully transcribe pipa music for violin. This dissertation talks briefly about Chinese music history and its categories and also focuses on the history and development of the pipa as well as its repertoire categories to provide context for the following musical examples. I use existing transcription examples from different categories of pipa music as an avenue to discuss how to transcribe pipa music for the violin. Even though the violin has some limitations for use as a plucked instrument, the instrument can still make use of several different kinds of techniques in order to play the music in a way that can represent certain features of the pipa while retaining the violin's characteristics.
The Expansion of a Retail Chain: An Analysis of Wal-Mart Locations in the United States
Retail geography is an expanding field that is becoming increasingly important within academia, the business environment, and the national and global economy. The focus of this study is to provide insight and additional understanding of the site selection processes employed by Wal-Mart in the United States. The research studies Wal-Mart from a national perspective and investigates the patterns of retail store expansion across the United States from 1990 to 2005. The study employs the use of a continuous Poisson model to check for significant clustering, and a single and multiple correlation analysis to identify the types of relationships that exist between retail stores and location. The results of the study make apparent several distinct patterns of retail store dispersion within the United States between the years 1990 to 2005.
Expansion of Musical Styles, Function of Texture, and Performing Techniques in Brian Lock's Sonic Archaeologies No. 1: A Performance Guide
British composer Brian Lock merges the composition styles of Alexander Goehr, Henryk Górecki and Witold Lutoslawski in his innovative works for instrumental sounds and electronics. His most recent work for flute, Sonic Archaeologies No.1, was premiered at the University of North Texas by Mary Karen Clardy, flute; Brian Lock, piano/electric keyboard; and Daniel Pardo, laptop/live mixing. The purpose of this dissertation is to provide flutists with artistic and technical guidance in preparing this work for flute, prerecorded orchestra, interactive electronics and improvisatory accompaniment. Sonic Archaeologies No. 1, a piece in five movements (Black Rain, Psychomania, Kodo, Susperia, and Deep in the Machine), incorporates contemporary techniques to create sounds other than the Western concert flute, with the use of live reinforcement devices such as microphones and time-based audio effects within a D.A.W. (Digital Audio Workstation.) Reggae, Hip-Hop and cinematic styles are juxtaposed within the work, fusing current genres with traditional rhythmic forms like the ones found in a bourrée. As the solo instrument, flute provides more textural than melodic elements, and the performer is required to interact with an unpredictable sonic soundscape as a result of the improvisatory element of the keyboards and computer. The notation of Sonic Archaeologies No.1 invites interpretation blending and altering traditional sounds through microphones and a processed signal flow. The performance guide will address acoustical considerations when the flute sound is being manipulated by dynamic and time-based processors in live performance; the interaction between the flute, electronics and acoustic spaces; the elements of sound production that provide interpretation of contemporary popular styles; and the opportunities for the performer to find, explore and develop artistry beyond the limitations of music notation.
An Expectancy-Value Model of Elective Music Participation
The purpose of this study was to specify and test a model detailing (a) gender, (b) previous elective music experience, (c) school, (d) music self-concept, and (e) music values as predictors of music enrollment and the initial juncture of school-sponsored elective music participation. In the event that a model with adequate fit was retained, a further purpose of this study was to calculate the direct, indirect, and total effects of each predictor, thereby determining each predictor's relative contribution towards explaining variance in elective music enrollment. Participants included fifth-grade students (N = 148) from two elementary schools. Data were gathered via administration of the Motivators of Elective Music Participation Questionnaire, and by accessing middle school elective enrollment records. The proposed expectancy-value model of elective music participation demonstrated excellent fit and was retained for interpretation. Overall, the model accounted for 34.4% of the variance in elective music participation. The greatest total predictor of elective music participation was previous elective music experience, followed closely by music values. Music self-concept, gender, and school played negligible roles in predicting whether students opted in or out of sixth-grade music electives.
The Experience of Language Use for Second Generation, Bilingual, Mexican American, 5th Grade Students
There is a paucity of research regarding language use among bilingual clients, particularly with Latino children. In order to provide culturally sensitive counseling for bilingual, Spanish-speaking, Latino children it is important to understand their experience of language use. The purpose of this study was to investigate how second generation, bilingual, Mexican American, 5th grade students experience language use in the two languages with which they communicate. I employed a phenomenological method to data collection and analysis and conducted semi-structured individual and group interviews with three boys and five girls (N = 8). Analysis of the individual and group interviews yielded four main structures: (a) dominant language determined perception of developing dual selves, (b) speaking two languages useful in language brokering and upward mobility, (c) dominant language determined experience of language use, and (d) language use and aspects of the complementarity principle. Findings from this study suggest that bilingual Latino children experience language brokering for their parents as difficult, speaking two languages as useful regarding upward mobility, and that their dominant language influences various aspects of their daily experiences such as with whom and where they use each language. Limitations to this research include insufficient time building rapport with participants and challenges related to unexplored dimensions of bilingualism in the counseling research literature. An overarching implication for future research, clinical practice, and counselor education is that bilingualism, language use, and the depth of experience of Latino children are largely understudied topics.
Experiences and Perceptions of Students in Music and Mathematics
Since the time of Pythagoras, philosophers, educators, and researchers have theorized that connections exist between music and mathematics. While there is little doubt that engaging in musical or mathematical activities stimulates brain activity at high levels and that increased student involvement fosters a greater learning environment, several questions remain to determine if musical stimulation actually improves mathematic performance. This study took a qualitative approach that allowed 24 high school students to express their direct experiences with music and mathematics, as well as their perceptions of how the two fields are related. Participants were divided into four equal groups based on school music participation and level of mathematic achievement, as determined by their performance on the Texas Assessment of Knowledge and Skills (TAKS). Students participated in a series of three interviews addressing their experiences in both music and mathematics, and took the Multiple Intelligences Developmental Assessment Scales (MIDAS). TAKS data and MIDAS information were triangulated with interview findings. Using a multiple intelligence lens, this study addressed the following questions: (a) How do students perceive themselves as musicians and mathematicians? (b) What experiences do students have in the fields of music and mathematics? (c) Where do students perceive themselves continuing in the fields of music and mathematics? and (d) How do students perceive the fields of music and mathematics relating to each other? Contrary to most existing literature, the students who perceived a connection between the two fields saw mathematics driving a deeper understanding of the musical element of rhythm. Not surprisingly, students with rich backgrounds in music and mathematics had a higher perception of the importance of those fields. Further, it became readily apparent that test data often played a minimal role in shaping student perceptions of themselves in the field of mathematics. Finally, it became apparent from listening to the …
Experiences Learning Interpersonal Neurobiology: an Interpretative Phenomenological Analysis
Neuroscience is increasingly part of the national dialogue regarding mental health. The field of interpersonal neurobiology may offer a framework for helping mental health professionals identify and apply the most relevant neuroscience principles to counseling. This study explored mental health professionals’ experiences learning IPNB. I conducted semi-structured interviews with participants (n = 6), all of whom were licensed mental health professionals and had completed a year-long study in the application of IPNB through Nurturing the Heart with the Brain in Mind. I analyzed the data, along with a research partner, according to interpretative phenomenological analysis (IPA) protocol. Four super-ordinate themes emerged from the analysis: (1) learning process as dynamic and engaging, (2) deepening knowledge and understanding of self and others, (3) personal and professional growth, and (4) impact on therapeutic practice. A number of sub-ordinate themes also emerged through the analysis , including experiential learning; learning through group process; influence of the past on the present; increased understanding of the change process; increased compassion, empathy, and acceptance for self and for others; increased confidence; using IPNB to educate clients; using IPNB to conceptualize clients; and using IPNB to select interventions. Finally, I identified three higher-order constructs that appeared embedded within and across themes: learning as ongoing, person of the participant, and person of the instructor. The findings in this study suggest that participants’ learning of IPNB had a significant impact on their personal and professional development, specifically in areas related to characteristics of effective counselors. The findings also suggest that these meaningful changes occurred in a learning environment characterized by emotional engagement, experiential activities, and group process. Limitations to this research, as well as further discussion of the results are included. Implications for future research, clinical practice, and counselor education are also offered.
Experiences of Latinos with Diabetes in the Central San Joaquin Valley
Embarking on a quest to uncover the shared experiences of Latinos with diabetes in the Central San Joaquin Valley is the principal issue discussed in this body of work. Diabetes is estimated to become a serious public health problem, with a current estimate of more than 30 million already afflicted. Engaging in participant-observation at a local clinic serving patients in a Diabetes Education Program and semi-structured interviews with Latinos attending the program, this research explores cultural experiences of diabetes. The primary aim of this research is to answer how health education information is accepted and interpreted based on cultural definitions of diabetes to inform diabetes management strategies.
Experimental Determination of L, Ostwald Solubility Solute Descriptor for Illegal Drugs By Gas Chromatography and Analysis By the Abraham Model
The experiment successfully established the mathematical correlations between the logarithm of retention time of illegal drugs with GC system and the solute descriptor L from the Abraham model. the experiment used the method of Gas Chromatography to analyze the samples of illegal drugs and obtain the retention time of each one. Using the Abraham model to calculate and analyze the sorption coefficient of illegal drugs is an effective way to estimate the drugs. Comparison of the experimental data and calculated data shows that the Abraham linear free energy relationship (LFER) model predicts retention behavior reasonably well for most compounds. It can calculate the solute descriptors of illegal drugs from the retention time of GC system. However, the illegal drugs chosen for this experiment were not all ideal for GC analysis. HPLC is the optimal instrument and will be used for future work. HPLC analysis of the illegal drug compounds will allow for the determination of all the solute descriptors allowing one to predict the illegal drugs behavior in various Abraham biological and medical equations. the results can be applied to predict the properties in biological and medical research which the data is difficult to measure. the Abraham model will predict more accurate results by increasing the samples with effective functional groups.
An Experimental Examination of the Effects of Fraud Specialist and Audit Mindsets on Fraud Risk Assessments and on the Development of Fraud-Related Problem Representations
Fraud risk assessment is an important audit process that has a direct impact on the effectiveness of auditors' fraud detection in an audit. However, prior literature has shown that auditors are generally poor at assessing fraud risk. The Public Company Accounting Oversight Board (PCAOB) suggests that auditors may improve their fraud risk assessment performance by adopting a fraud specialist mindset. A fraud specialist mindset is a special way of thinking about accounting records. While auditors think about the company's recorded transactions in terms of the availability of supporting documentations and the authenticity of the audit trail, fraud specialists think instead of accounting records in terms of the authenticity of the events and activities that are behind the reported transactions. Currently there is no study that has examined the effects of the fraud specialist mindset on auditors' fraud risk assessment performance. In addition, although recent studies have found that fraud specialists are more sensitive than auditors in discerning fraud risk factors in situation where a high level of fraud risk is present, it remains unclear whether the same can be said for situation where the risk of fraud is low. Thus, the purpose of my dissertation is to examine the effects of fraud specialist and audit mindsets on fraud risk assessment performance. In addition, I examined such effects on fraud risk assessment performance in both high and low fraud risk conditions. The contributions of my dissertation include being the first to experimentally examine how different mindsets impact fraud-related judgment. The results of my study have the potential to help address the PCAOB's desire to improve auditors' fraud risk assessment performance though the adoption of the fraud specialist mindset. In addition, my study contributes to the literature by exploring fraud-related problem representation as a possible mediator of mindset on fraud risk assessment …
An Experimental Examination Of The Effects Of Goal Framing And Time Pressure On Auditors’ Professional Skepticism
Professional skepticism is a critical component of audit practice and current auditing standards direct auditors to remain skeptical throughout the duration of each audit engagement. Despite the importance and prevalence of an emphasis on professional skepticism throughout auditing standards, evidence indicates that auditors often fail to exercise an appropriate degree of professional skepticism. Prior accounting research suggests that auditors’ professionally skeptical behavior is affected by individual personality traits as well as situational (state) influences, whereby both factors contribute to auditor professional skepticism. Yet, prior research has primarily focused on trait skepticism; and little research to date has investigated the concept of state skepticism. The purpose if this research study is to experimentally investigate the impact of time pressure and trait skepticism on state skepticism, and to test a potential debiasing procedure on the impact of time pressure on state skepticism. In addition, this study examines the influence of both skepticism types on skeptical behavior.This research offers several contributions to accounting literature and practice. First, I contribute to the existing debate regarding the influences of professional skepticism by providing evidence that professional skepticism may be categorized as a temporary state, induced by situational aspects, in addition to being classified as an enduring trait. Second, I identify certain situational conditions which create differences in the level of state professional skepticism exhibited within an auditing context. Lastly, my findings may also be important to audit firms as they consider tools within their training arsenal equipped to promote an appropriate level of professional skepticism among employees. If auditor skepticism can be influenced by the frames they are provided, then audit firms may create an environment that promotes consistency in auditors’ application of professional skepticism, simply by engaging in goal framing.
An Experimental Study of Bifurcated (Weekend and Weekday) and Unitary (Past Week) Retrospective Assessments of Sleep
Discordance between weekday and weekend sleep schedules is common (Bonnet & Arand, 1995; Breslau, Roth, Rosenthal, & Andreski, 1997; Machado, Varella, & Andrade, 1998; Strauch & Meier, 1988; Tsai & Li, 2004). Brief retrospective self-report measures are essential for epidemiological research studies (Moul, Hall, Pilkonis, & Buysse, 2004), but self-reports are prone to error in recall, and the greater the variability in nightly sleep, the less reliable are retrospective reports (Babkoff, Weller, & Lavidor, 1996). More accurate self-report responses may be possible if measures prompt participants to consider variations in sleep schedules that are consistent (i.e., weekday and weekend sleep schedules). The current study experimentally examined whether Bifurcated (Weekday and Weekend) retrospective assessments of sleep are more accurate than Unitary (Past Week) assessments. Participants were randomly assigned to complete one of the two versions (Bifurcated vs. Unitary) of the Sleep Questionnaire. One hundred and thirty-one participants were included in the analyses. Results of a a series of analyses demonstrated that the Bifurcated version of the Sleep Questionnaire provided more accurate and less variable estimates of total sleep time than the Unitary version of the Sleep Questionnaire. Differences between the versions of the Sleep Questionnaire for other sleep variables were less consistent, and the increased length of the Bifurcated version of the Sleep Questionnaire may have contributed to increased missing and unusable data in this group. Overall, the findings suggest that in both research and clinical work, retrospective measures that examine weekday and weekend sleep separately may offer advantages over retrospective measures that do not differentiate between weekday and weekend sleep.
An Experimental Study of Mindfulness and Acceptance-Based Skills for Internalized Ageism in Older Adults and College Students
This project explored whether mindfulness and acceptance-based practices (MABPs) for older adults would reduce the negative effects of ageism and negative attitudes and beliefs related to aging. In addition, state affect and stress were explored. This study used an experimental design to compare two groups of older adults and two groups of undergraduate students – those who received a MABP and those who did not, after being presented with negative ageist stereotypes. Condition and condition by age sample comparisons revealed several findings. Following the MABP, undergraduates who received a MABP had significantly lower ageism scores than did undergraduates who did not. Older adult findings were opposite of proposed hypotheses, with older adults having higher scores on ageism after receiving the MABP, as compared to the scores of older adults who were in the comparison condition. Differences in state mindfulness were seen between conditions, with the MABP condition exhibiting more state mindfulness than in the comparison condition. However, there was no significant condition by age sample interaction effect. Change scores for state affect after the MABP were non-significant at either level of analysis, and older adults showed no difference in digit span stress scores based on their condition assignment. Exploratory analyses revealed some research consistent, as well as nuanced, findings. These findings suggest that undergraduates may respond to MABPs for recontextualizing aging, discrimination, and stigma. These findings also suggest that older adults may employ different coping strategies when confronted with ageism in an experimental context when asked to reflect, as oppose to participate in MABPs. Overall, a need for aging education, experimental research with older adults, and empirical understandings of MABPs for age-related issues, is needed. Limitations and future directions are discussed.
Experimental Study on Fluidization of Biomass, Inert Particles, and Biomass/Sand Mixtures
Fluidization of biomass particles is an important process in the gasification, pyrolysis and combustion in order to extract energy from biomass. Studies on the fluidization of biomass particles (corn cob and walnut shell), inert particles (sand, glass bead, and alumina), which are added to facilitate fluidization of biomass, and biomass/sand mixture were performed. Experiments were carried out in a 14.5 cm internal diameter cold flow fluidization bed to determine minimum fluidization velocities with air as fluidizing medium. On the of basis of experimental data from both present work and those found in the literature, new correlations were developed to predict minimum fluidization velocity for inert particles as well as biomass particles. It was found that the proposed correlations satisfactorily predict minimum fluidization velocities and was in well agreement with experimental data. Furthermore, effect of weight percentage of biomass in the biomass/sand mixtures was studied. The weight fraction of biomass particles in the mixture was chosen in the range of 0 ~ 100 wt. %. The results show that minimum fluidization velocity of the mixtures increases with an increase in biomass content. Using the present experimental data, a new correlation was developed in terms of mass ratio for predicting values of minimum fluidization velocity of these mixtures. However, the validity of the proposed correlation should be further studied by conducting more experiments using the biomass/sand mixtures of different particle size, shape, and density.
An Experimental Study on Situated and Dynamic Learning Assessment (SDLA) Environment
The current supplementary web based English learning in Taiwan provides online learning resources and gives assessments at the end of each lesson to evaluate learners' online learning results. Based on the testing results, instructors may adjust their in-class instructional method to focus on the students' weaknesses. For the average classroom size of 40 students with one instructor, it is extremely difficult to provide individual learning content for each learner's needs because each student has his or her own weaknesses. This study conducted the situated environment with Vygotsky's dynamic assessment theory to test learner's learning achievements and satisfactions as compared to the current web learning environment. The study finds that when both groups of Taiwanese students used Internet based learning, those that utilized the situated and dynamic learning assessment environment showed a statistically significant higher achievement score than those using only the current online learning environment (p < .01). In addition, learners in the SDLA environment had statistically significant higher satisfaction scores than those in the current web learning environment.
Expertise Revisited: Reflecting on the Intersection of Science and Democracy in the Case of Fracking
This dissertation aims to explain the conditions under which expertise can undermine democratic decision making. I argue that the root of the conflict between expertise and democracy lies in what I call insufficiently “representative” expertise – that is forms of scientific research that are not relevant to the policy questions at hand and that fail to make visible their hidden values dimensions. I claim that the scholarly literature on the problem of expertise fails to recognize and address the issue correctly, because it does not open the black box of scientific methodologies. I maintain that only by making sense of the methodological choices of experts in the context of policy making can we determine the relevance of research and reveal the hidden socio-political values and consequences. Using the case of natural gas fracking, I demonstrate how expert contributions – even though epistemically sound – can muddle democratic policy processes. I present four case studies from controversies about fracking to show how to contextualize scientific methodologies in the pertinent political process. I argue that the common problem across all case studies is the failure of expertise to sufficiently represent stakeholders’ problems and concerns. In this context, “representation” has three criteria: (1) the operational research questions on which the qualified experts work are relevant to stakeholders’ problems and concerns; (2) the non-epistemic values and consequences of epistemic choices of experts are compatible with social and political values and priorities; and (3) hidden values attached to facts are fully transparent and openly debated. In the conclusion, I propose a normative version of this representation theory that can be used to evaluate the appropriateness of expertise for democratic policy making. Instead of the value-free science ideal, I propose a new ideal to legitimately allow non-epistemic values in scientific reasoning without compromising the soundness of …
Explaining Economic Development Strategies Using Product Differentiation Theory: a Reconceptualization of Competition Among City Governments
Local governments do not operate in a vacuum. Instead, they are part of a complex “polycentric” system of governments where politically autonomous and self-ruled cities compete with one another over taxable wealth. Missing from the scholarship on metropolitan governance is an understanding of the factors driving competition among local governments. The purpose of this dissertation is to fill this gap by examining how interjurisdictional competition over economic development impacts a city’s choice of strategies for attracting business and residential investment and how those strategies affect revenue collection. First, this dissertation examines whether cities, knowing the economic development strategies of their neighboring cities, pursue similar types of businesses? Or do cities strategically target different types of businesses as a way to avoid the negative consequences of competition? Second, this dissertation explores what impact the decision to pursue similar or dissimilar businesses has on the revenue collection of local governments. Using spatial data analysis to analyze a sample of 2,299 cities, this dissertation finds general support for both theoretical frameworks presented. Overall, the findings from both analyses provide unique insights into metropolitan governance and interjurisdictional competition.
Explaining “Everyday Crime”: A Test of Anomie and Relative Deprivation Theory
Every day, individuals commit acts which are considered immoral, unethical, even criminal, often to gain material advantage. Many people consider cheating on taxes, cheating on tests, claiming false benefits, or avoiding transport fare to be wrong, but they do them anyway. While some of these acts may not be formally illegal, they are, at best, considered morally dubious and is labeled “everyday crime.” Anomie theory holds that individuals make decisions based on socialized values, which separately may be contradictory but together, balances each other out, producing behavior considered “normal” by society. When one holds an imbalanced set of values, decisions made on that set may produce deviant behavior, such as everyday crime. RD theory holds that individuals who perceive their own deprivation, relative to someone else, will feel frustration and injustice, and may attempt to ameliorate that feeling with deviant behavior. Data from the 2006 World Values Survey were analyzed using logistic regression, testing both constructs concurrently. An individual was 1.55 times more likely to justify everyday crime for each calculated unit of anomie; and 1.10 times more likely for each calculated unit of RD. It was concluded from this study that anomie and relative deprivation were both associated with the tendency towards everyday crime.
Explaining Marijuana Use Among Turkish Juveniles: A Test of Hirschi's Social Bonding Theory
Marijuana is the most prevalent illicit drug used in the world and among Turkish juveniles. Although studies have examined marijuana use among Turkish juveniles, none has tested Hirschi's social bonding theory, one of the most frequently tested and applied criminological theories in the United States and other Western and developed countries. This study investigated the empirical validity and generalizability of Hirschi's theory to juveniles' marijuana use in Turkey, a non-Western and developing country. Data on 2,740 Turkish tenth grade students from the 2006 Youth in Europe survey were used. Results from binary logistic regression analyses were generally consistent with the propositions of Hirschi's theory and the findings of previous empirical studies. Regarding the attachment component of the theory, Turkish juveniles who lived in two-parent families and those who were closely monitored by their parents were less likely to have tried marijuana. In addition, teens who were strongly attached to their school and religion were also less likely to have used the drug. As for the commitment component, language grade was negatively associated with marijuana use. None of the involvement items had significant effects on marijuana use in the predicted direction. Participation in club sports had a positive effect on marijuana use. Belief items, such as acceptance of societal norms, values, and rules, had the predicted inhibiting effects on teens' marijuana use. Of the six sociodemographic/controls included in the analyses, only gender had a significant effect; male students were more likely to have tried marijuana than the female peers. Policy implications of the results for adolescents, parents, and schools are discussed.
Explaining the Homeland-Diaspora Nexus: Israel Motivated Violence and Its Consequences
This dissertation examines the homeland-diaspora nexus with a focus on how homeland conflict affects diaspora targeting and insecurity in Israel.
Explaining the Relationship Between Borderline Personality Features and Suicidal Ideation
Researchers have previously identified substance use and borderline personality disorder as factors that increase risk for suicidal thoughts and behaviors. This study explored the relationship between these factors in samples of students and individuals seeking outpatient treatment. Supplemental data collected via the internet (MTurk) also looked at experiential avoidance (EA) with the Avoidance and Fusion Questionnaire for Youth. The Structured Clinical Interview for the DSM-IV, Alcohol Use Disorders Identification Test, Scale for Suicide Ideation, and Personality Assessment Inventory- Borderline Features Scale elicited information regarding severity and/or frequency of substance use, suicidal thoughts, and borderline features respectively. Additionally, the Psychiatric Diagnostic Screening Questionnaire was administered to the UNT sample. The UNT sample analyses indicate substance use moderates, strengthening, the relationship between borderline features and current suicidal thoughts. However, severity of suicidal thoughts was lower for individuals high in both borderline features and substance use disorder symptoms compared to those low in borderline features and high in substance use symptoms. The MTurk sample analyses suggest substance use functions as a mediator. A robust relationship existed between substance use severity and EA, showing substance use as a behavioral marker for EA. In conclusion, concurrent treatment of substance use and borderline personality features would be beneficial in reducing risk for suicidal thoughts. Further investigation into the role and utility of addressing EA is warranted.
Explanation for the Variation of Women’s Rights Among Moderate Muslim Countries
Due to the actions of radicals and extremists, many in the West have come to view Islam as a religion of gender inequality that perpetuates the severe oppression of women. However, there is actually great variation in women’s rights across Muslim countries. This thesis presents a theoretical framework seeking to explain this variation, by examining differences in family law. The theory supposes that variation can be explained by the strategic actions of political leaders. From this theory, I hypothesize that the variations in women’s rights come from the variation in family law, which in large, are due to the existence of groups threatening the power of the political leaders, and the leader’s subsequent understanding of this threat. Using a most similar systems research design, I examine 4 moderate Muslim countries, Turkey, Tunisia, Morocco, and Egypt. Through case study research, I find limited support for the above hypothesis.
Explicating the Managerial Processes of Dynamic Capabilities and Investigating How the Reconceptualized Construct Influences the Alignment of Ordinary Capabilities
In the last three decades, strategic management scholars have explored the organization’s need to reconfigure its capabilities to leverage opportunities in a changing environment. The first objective of this study was to identify the underlying elements of the managerial processes of dynamic capabilities, and to offer a reconceptualization of the dynamic capabilities construct. The second objective of this investigation was to determine how the reconceptualized dynamic capabilities construct could influence the alignment of ordinary capabilities. Findings from this investigation indicate that organizational processes and managerial processes are unique components of dynamic capabilities. In addition, these organizational processes were found to be significantly and positively correlated with the alignment of ordinary capabilities. Furthermore, managerial processes were found to moderate the relationship between organizational processes and one type of ordinary capability alignment (i.e. innovation-operations capability alignment). Taken together, the findings of this study support the notion that dynamic capabilities are context specific, and that understanding how they influence the organization’s ability to change is complex. The developments and findings in this study offer a reconceptualized and empirically tested framework for the capability alignment process, thereby providing a more comprehensive picture of the underlying processes.
An Exploration of Altruistic Behavior of Substance-Abuse Facilities According to Their Ownership Status
Using the 2009 National Survey of Substance Abuse Treatment Services (N-SSATS), this paper uses logistic regressions to explore the effect of facility ownership on a facility’s show of altruism. Facility’s show of altruism is operationalized as a facility offering free treatment to all its clients, free treatment to some of its clients, or a facility offering a sliding fee scale to its client base in order to absorb some of the cost of treatment based on a potential client's income. Region, receipt of public funds, and religious affiliation are added as covariates in order to gauge whether the potential relationship between facility ownership and a facility’s show of altruism is genuine. Results indicate that private, for-profit ownership status of a facility is associated with a lower likelihood that a substance-abuse treatment facility would engage in altruistic behavior. However, receipt of public funds acts as a mediating variable, in that, its inclusion raises the likelihood that a private, for-profit facility would engage in shows of altruism. Furthermore, it appears that religious-affiliation increases the likelihood that a facility would display altruism by providing free treatment, to some of its clients, or to all, but less likely to display altruism by employing a sliding fee scale. Overall, inclusion of region, receipt of public funds, and religious affiliation all produce statistically significant results, along with facility ownership. This suggests that there are a variety of variables, apart from facility ownership alone, that might be influential over a facility's show of altruism.
An Exploration of College Attitudes among Sioux Falls High School Students
Since the recession of 2008, there has been an increased scrutiny of higher education, with little research done on how this affects high school students' college search process. This study seeks to understand how college perceptions are formed and how they affect the college decision process of high school students in Sioux Falls, South Dakota. In order to gain a holistic perspective of this process, this study utilized a mixed method approach of analyzing public data, conducting interviews with community members and students, conducting a focus group with high school guidance counselors, and administering a survey to high school students. This study found that students in this area form their perceptions of college in three distinct phases and that these phases affect a student's college priorities. Special attention was given to how academics, cost and location contributed to a student's overall college decision. These findings can be used to assist faculty and staff at higher education institutions in creating effective messaging and programming that relate to this group of students.
An Exploration of Elementary L2 Learners' Use of Metacognitive Strategies
This multiple case study examined the experiences of elementary L2 learners who received instruction in either reciprocal teaching or the think aloud strategy (TAS), and identified patterns of use that emerged from participants' employment of the strategies. The three L2 participants took a pre- test and a posttest, were recorded using the strategies, and responded to interview questions about the strategies. Using qualitative data analysis techniques, four themes emerged from analysis of the data, including; talking like a teacher, I know what I know, established strategies, and declines to use the steps in the strategy. Implications from these findings suggest that the discussion facilitated by reciprocal teaching assists elementary L2 participants in better understanding the text and also supports their language acquisition, whereas TAS does not facilitate discussion. Further, even though reciprocal teaching promotes discussion, teacher assistance during discussion is necessary. Finally, it is essential that teachers are mindful of students' understandings of topics and the difficulty of texts used when students are learning the strategies.
Exploration Of Energy And Area Efficient Techniques For Coarse-grained Reconfigurable Fabrics
Coarse-grained fabrics are comprised of multi-bit configurable logic blocks and configurable interconnect. This work is focused on area and energy optimization techniques for coarse-grained reconfigurable fabric architectures. In this work, a variety of design techniques have been explored to improve the utilization of computational resources and increase energy savings. This includes splitting, folding, multi-level vertical interconnect. In addition to this, I have also studied fully connected homogeneous and heterogeneous architectures, and 3D architecture. I have also examined some of the hybrid strategies of computation unit’s arrangements. In order to perform energy and area analysis, I selected a set of signal and image processing benchmarks from MediaBench suite. I implemented various fabric architectures on 90nm ASIC process from Synopsys. Results show area improvement with energy savings as compared to baseline architecture.
