Determining the Authenticity of the Concerto for Two Horns, Woo 19, Attributed to Ferdinand Ries
Ferdinand Ries is credited as the composer of the Concerto for Two Horns, WoO. 19 preserved in the Berlin State Library. Dated 1811, ostensibly Ries wrote it in the same year as his Horn Sonata, Op. 34, yet the writing for the horns in the Concerto is significantly more demanding. Furthermore, Ries added to the mystery by not claiming the Concerto in his personal catalog of works or mentioning it in any surviving correspondence. The purpose of this dissertation is to study the authorship of the Concerto for Two Horns and offer possible explanations for the variance in horn writing. Biographical information of Ries is given followed by a stylistic analysis of Ries’s known works. A stylistic analysis of the Concerto for Two Horns, WoO. 19 is offered, including a handwriting comparison between the Concerto for Two Horns and Ries’s Horn Sonata. Finally, possible explanations are proposed that rationalize the variance in horn writing between the Concerto for Two Horns, WoO. 19 and Ries’s other compositions that include the horn.

The Musical Language of Alberto Ginastera’s Panambí and the Influence of Claude Debussy’s La Mer and Igor Stravinsky’s Le Sacre Du Printemps
Alberto Ginastera completed his ballet Panambí in 1937. The ballet was arranged as a symphonic suite, and was performed the same year at the Teatro Colon in Buenos Aires, conducted by Juan José Castro. Panambí marked the beginning of Alberto Ginastera’s long and successful career as an Argentine composer. Chapter I of this document provides a brief introduction into the history behind Alberto Ginastera’s Panambí suite, and includes a review of the research that is exclusively devoted to the suite, as well as documents that do not provide direct analyses of Panambí, but contain information that aid in a better understanding of the suite’s composition. Chapter II includes analyses of the suite that illustrate important elements that contribute to the structure and sound of the Panambí suite. These components include Ginastera’s construction of the La Noche theme found in the first movement and its use as a master set, his use of diatonic collections and pitch centricity, the importance of unordered pitch class intervals IC1 and IC6, his use of aggregate completion as a compositional method, and his use of local motives over larger spans of temporal space. Chapter III explores the possibility that many of these compositional methods are …

Weigh-in Environment and Weight Intentionality and Management of Female Collegiate Athletes
Research suggests that female athletes, in particular, experience “sport-environment” pressures such as: weight, performance, and body image demands from their coaches, teammates, and judges. These influences in tandem with society’s portrayal of the thin ideal are thought to considerably increase the risk of developing disordered eating problems in this population. Although numerous studies have been conducted over the past decade on the prevalence of eating disorders and pathogenic weight control behaviors among female athletes, few have examined in detail the weight pressures that exist within the sport environment, such as whether or not (and how often) athletes are weighed by their coaches, and how athletes respond to those pressures in terms of weight management practices. In the proposed study, we will examine the weigh-in environment, weight satisfaction, weight management practices, menstrual health, and reported source of nutritional guidance. The sample includes 414 NCAA Division I female collegiate swimmers/divers and gymnasts drawn from 26 universities across the U.S. Participants anonymously completed a series of questionnaires as part of a larger study on student-athlete health and well-being. This study found that 41% of athletes were weighed, and most often by an athletic trainer in private. Despite most weigh-ins were reportedly conducted in …

Musical Borrowing in the Choral Music of Andrew Rindfleisch
American composer Andrew Rindfleisch (b. 1963) has contributed twenty-one pieces to the repertoire of contemporary choral literature to date. His works have been commissioned, premiered, and recorded by notable choral ensembles and performed in significant venues around the country. Influenced by his own early choral singing experience in his native Wisconsin, much of Rindfleisch’s choral music is infused with influences of the music of earlier composers and choral idioms. With these works, Rindfleisch participates in a long-standing trend in choral composition of looking to the musical past for inspiration and procedure while writing in a contemporary harmonic vocabulary, and his efforts can be evaluated through the lens of a study of musical borrowing. Through a case study of five of Rindfleisch’s choral works – “In manus tuas,” “Mille regretz,” “Psalm,” “Anthem,” and “Graue Liebesschlangen” – this document identifies common characteristics of Rindfleisch’s choral music and demonstrates his uses of musical borrowing and allusion. The influence of Renaissance polyphony, Debussy, Brahms, and German expressionism is revealed.

Fundamental Studies of Copper Corrosion in Interconnect Fabrication Process and Spectroscopic Investigation of Low-k Structures
In the first part of this dissertation, copper bimetallic corrosion and its inhibition in cleaning processes involved in interconnect fabrication is explored. In microelectronics fabrication, post chemical mechanical polishing (CMP) cleaning is required to remove organic contaminants and particles left on copper interconnects after the CMP process. Use of cleaning solutions, however, causes serious reliability issues due to corrosion and recession of the interconnects. In this study, different azole compounds are explored and pyrazole is found out to be a potentially superior Cu corrosion inhibitor, compared to the most widely used benzotriazole (BTA), for tetramethyl ammonium hydroxide (TMAH)-based post CMP cleaning solutions at pH 14. Micropattern corrosion screening results and electrochemical impedance spectroscopy (EIS) revealed that 1 mM Pyrazole in 8 wt% TMAH solution inhibits Cu corrosion more effectively than 10 mM benzotriazole (BTA) under same conditions. Moreover, water contact angle measurement results also showed that Pyrazole-treated Cu surfaces are relatively hydrophilic compared to those treated with BTA/TMAH. X-ray photoelectron spectroscopy (XPS) analysis supports Cu-Pyrazole complex formation on the Cu surface. Overall Cu corrosion rate in TMAH-based highly alkaline post CMP cleaning solution is shown to be considerably reduced to less than 1Å/min by addition of 1 mM Pyrazole. In …

The Impact of Computational Methods on Transition Metal-containing Species
Quantum chemistry methodologies can be used to address a wide variety of chemical problems. Key to the success of quantum chemistry methodologies, however, is the selection of suitable methodologies for specific problems of interest, which often requires significant assessment. To gauge a number of methodologies, the utility of density functionals (BLYP, B97D, TPSS, M06L, PBE0, B3LYP, M06, and TPSSh) in predicting reaction energetics was examined for model studies of C-O bond activation of methoxyethane and methanol. These species provide excellent representative examples of lignin degradation via C-O bond cleavage. PBE0, which performed better than other considered DFT functionals, was used to investigate late 3d (Fe, Co, and Ni), 4d (Ru, Rh, and Pd), and 5d (Re, Os, and Ir) transition metal atom mediated Cβ -O bond activation of the β–O–4 linkage of lignin. Additionally, the impact of the choice of DFT functionals, basis sets, implicit solvation models, and layered quantum chemical methods (i.e., ONIOM, Our Own N-layered Integrated molecular Orbital and molecular Mechanics) was investigated for the prediction of pKa for a set of Ni-group metal hydrides (M = Ni, Pd, and Pt) in acetonitrile. These investigations have provided insight about the utility of a number of theoretical methods in …

Shame Due to Heterosexism, Self-esteem and Perceived Stress: Correlates of Psychological Quality of Life in a Lesbian, Gay and Bisexual Sample
Sexual minorities experience higher levels of stress than heterosexuals, which in turn affects coping and psychological quality of life (PQOL). Although many sexual minorities remain mentally healthy, a higher prevalence of mental disorders among members of the lesbian, gay and bisexual (LGB) communities exists; thus, LGB PQOL becomes an important area to examine. Several key factors are related to PQOL: shame due to heterosexism, self-esteem and perceived stress. Using minority stress model, I hypothesized that shame due to heterosexism and perceived stress are negatively correlated with PQOL, while self-esteem is positively correlated with PQOL. I hypothesized that collectively shame due to heterosexism, self-esteem and perceived stress account for a significant proportion of the variance in PQOL, that self-esteem moderates the relationship between perceived stress and PQOL and that age moderates the relationship between shame due to heterosexism and PQOL. I calculated Pearson product-moment correlation coefficient and found shame due to heterosexism was negatively correlated with PQOL (r(146) = -.21, p = .009), perceived stress was negatively correlated with PQOL (r (146) = -.69, p < .001) and self-esteem was positively correlated with PQOL (r(146) = .72, p < .001). I conducted a regression analysis and found our model accounted for …

Role of GPR17 in Thrombocyte Aggregation in Adult Zebrafish
GPR17, a uracil nucleotide cysteinyl leukotriene receptor, belongs to the GPCR (G protein coupled receptor) family. It has been shown recently that inhibiting this protein in the nervous system in mice can lead to blockage of oligodendrocyte maturation, which supports myelin repair. Interestingly, our laboratory found GPR17 in thrombocytes. However, we do not know whether it has any function in thrombocyte aggregation or the nature of the ligand. In this paper, we studied the role of GPR17 in hemostasis, which is a fundamental defense mechanism in the event of injury. Using zebrafish as a model system, our laboratory has studied specifically thrombocytes, which play a significant role in hemostasis. The major reasons to use zebrafish as a model system are that their thrombocytes are functionally equivalent to human platelets, the adult fish are amenable to knockdown experiments, and they are readily available in the market. This study was performed by using a piggy back knockdown method where we used a chemical hybrid of control morpholino and an antisense oligonucleotide sequence leads to the degradation the mRNA for GPR17. After knockdown GPR17 in thrombocytes, the percent difference of the thrombocytes aggregation between the control and knockdown blood samples was measured by …

On City Identity and Its Moral Dimensions
The majority of people on Earth now live in cities, and estimates hold that 60 percent of the world’s cities have yet to be built. Now is the time for philosophers to develop a philosophy of the city to address the forthcoming issues that urbanization will bring. In this dissertation, I respond to this need for a philosophy of the city by developing a theory of city identity, developing some of the theory’s normative implications, illustrating the theory with a case study, and outlining the nature and future of philosophy of the city more generally. Indeed, this dissertation is only a part of my larger project of founding and institutionalizing this new field of both academic and socially-engaged philosophical activity. Throughout the history of the discipline, other areas such a personal identity have received numerous considerations, along with the concept of identity as an abstraction. For example, there is a bounty of research addressing problems pertaining to how objects and people retain an identity over time and claims about identity in general. While one could argue that cities are not any different than any other object, such an account fails to consider that a city’s dynamic nature makes it dissimilar …

Photoinduced Toxicity in Early Lifestage Fiddler Crab (Uca longisignalis) Following Exposure to Deepwater Horizon Spill Oil
The 2010 Deepwater Horizon (DWH) oil spill resulted in a large release of polycyclic aromatic hydrocarbons (PAH) into the Gulf of Mexico. PAH can interact with ultraviolet radiation (UV) resulting in increased toxicity, particularly to early lifestage organisms. The goal of this research was to determine the sensitivity of fiddler crab larvae (Uca longisignalis) to photo-induced toxicity following exposure to Deepwater Horizon spill oil in support of the DWH Natural Resource Damage Assessment. Five replicate dishes each containing 20 larvae, were exposed to one of three UV treatments (10%, 50%, and 100% ambient natural sunlight) and one of five dilutions of water accommodated fractions of two naturally weathered source oils. A dose dependent effect of PAH and UV on larval mortality was observed. Mortality was markedly higher in PAH treatments that included co-exposure to more intense UV light. PAH treatments under low intensity sunlight had relatively high survival. These data demonstrate the importance of considering combined effects of non-chemical (i.e. UV exposure) and chemical stressors and the potential for photo-induced effects after exposure to PAH following the Deepwater Horizon spill.

Thresholds and Legacy Effects of Tropical Floodplain Fish Assemblages in Response to Flood Attributes
Natural flow regimes are critical for sustaining biodiversity and river integrity. Floods and droughts form an important component of river systems and control population sizes and species diversity across space and time. Modification of flow regimes, including disruption of the timing, magnitude and duration of flooding, is a global problem, and many new impoundments are planned for large river-floodplain ecosystems in the tropics. Flow modifications may cause dramatic non-linear responses in population sizes and have lasting effects through time, but such topics are poorly investigated over multi-year scales, especially in highly diverse tropical ecosystems. Using a long-term dataset from the Upper Paraná River floodplain, Brazil, I tested for threshold and legacy effects of fish assemblages to flood attributes, such as timing, magnitude, duration, rate of change and variation. Specifically, I hypothesized that long duration, high magnitude floods would elicit threshold responses in long-distance migratory fish species and these responses result in significant legacy effects detectable over multiple years. Consistent positive threshold responses to increasing flood duration and magnitude were detected for many species and not significantly correlated with reproductive guilds. Legacy effects were prevalent (i.e. identified for more than 90% of species) and including flood attributes from previous years increased …

Identification of Genes Involved in Flocculation by Whole Genome Sequencing of Thauera aminoaromatica Strain MZ1T Floc-defective Mutants
Thauera aminoaromatica MZ1T, a floc-forming bacterium isolated from an industrial activated sludge wastewater treatment plant, overproduces exopolysaccharide (EPS) leading to viscous bulking. This phenomenon results in poor sludge settling and dewatering during the clarification process. To identify genes responsible for bacterial flocculation, a whole genome phenotypic sequencing technique was applied. Genomic DNA of MZ1T flocculation-deficient mutants were subjected to massively parallel sequencing. The resultant high-quality reads were assembled and compared to the reference genome of the wild type genome. We identified nine nonsynonymous mutations and one nonsense mutation putatively involved in EPS biosynthesis. Complementation of the nonsense mutation located in an EPS deacetylase gene restored the flocculating phenotype. The FTIR spectra of EPS isolated from the wild-type showed reduced C=O peak of the N-acetyl group at 1665 cm-1 as compared to the spectra of MZ1T floc-deficient mutant EPS, suggesting that the WT EPS was partially deacetylated. Gene expression analysis also demonstrated the deacetylase gene transcript increased before flocculation occurred. The results suggest that the deacetylation of MZ1T EPS is crucial for flocculation. The information obtained from this study will be useful for preventing viscous bulking and wastewater treatment system failure, and may have potential applications in the biotechnology sector for …

An Accelerometer-based Gesture Recognition System for a Tactical Communications Application
In modern society, computers are primarily interacted with via keyboards, touch screens, voice recognition, video analysis, and many others. For certain applications, these methods may be the most efficient interface. However, there are applications that we can conceive where a more natural interface could be convenient and connect humans and computers in a more intuitive and natural way. These applications are gesture recognition systems and range from the interpretation of sign language by a computer to virtual reality control. This Thesis proposes a gesture recognition system that primarily uses accelerometers to capture gestures from a tactical communications application. A segmentation algorithm is developed based on the accelerometer energy to segment these gestures from an input sequence. Using signal processing and machine learning techniques, the segments are reduced to mathematical features and classified with support vector machines. Experimental results show that the system achieves an overall gesture recognition accuracy of 98.9%. Additional methods, such as non-gesture recognition/suppression, are also proposed and tested.

Hâfez and Betinis: a Conductor’s Approach to Ancient Persian Poetry As Voiced by a Twenty-first Century, Western Composer
The choral music of Abbie Betinis is being widely performed and commissioned by prominent high school, university, and civic choruses. This study examines From Behind the Caravan: Songs of Hâfez, a five-movement work by Betinis for women’s chorus, vielle, oud, and Persian percussion. Four ghazals by Hâfez of Shiraz, a fourteenth century Sufi poet, are used as the text for Betinis’s Caravan. When considering a performance of this work, a conductor must understand proper treatment of the text, available translation options, Hâfez’s vast world of imagery, vocal demands inherent to the work, alternate instrumentations available and the benefits of each, how to approach improvisatory passages, how to engage heterophonic elements, and how to prepare a Western choir and audience with very little to no understanding of the philosophies of Sufism that heavily influence the work. This study addresses the body of practical knowledge gained after a year of examining, researching, teaching, and performing this work.

Thin Cr2O3 (0001) Films and Co (0001) Films Fabrication for Spintronics
The growth of Co (0001) films and Cr2O3 (0001)/Co (0001) has been investigated using surface analysis methods. Such films are of potential importance for a variety of spintronics applications. Co films were directly deposited on commercial Al2O3 (0001) substrates by magnetron sputter deposition or by molecular beam epitaxy (MBE), with thicknesses of ~1000Å or 30Å, respectively. Low Energy Electron Diffraction (LEED) shows hexagonal (1x1) pattern for expected epitaxial films grown at 800 K to ensure the hexagonally close-packed structure. X-ray photoemission spectroscopy (XPS) indicates the metallic cobalt binding energy for Co (2p3/2) peak, which is at 778.1eV. Atomic force microscopy (AFM) indicates the root mean square (rms) roughness of Co films has been dramatically reduced from 10 nm to 0.6 nm by optimization of experiment parameters, especially Ar pressure during plasma deposition. Ultrathin Cr2O3 films (10 to 25 Å) have been successfully fabricated on 1000Å Co (0001) films by MBE. LEED data indicate Cr2O3 has C6v symmetry and bifurcated spots from Co to Cr2O3 with Cr2O3 thickness less than 6 Å. XPS indicates the binding energy of Cr 2p(3/2) is at 576.6eV which is metallic oxide peak. XPS also shows the growth of Cr2O3 on Co (0001) form a thin …

The Role of Family in Alcohol Consumption Among Turkish Adolescents
Alcohol consumption among adolescents is an important issue because of its link to many negative social and health problems, including depression, suicide, and aggression. Drawing from Hirschi’s social bonding theory and Agnew’s general strain theory, this study examines the effects of family relations on alcohol consumption among Turkish adolescents. Social bonding theory suggests that individuals with stronger social bonds are less likely to use alcohol than individuals with weaker social bonds. General strain theory, on the other hand, proposes that individuals with higher levels of strain due to financial difficulties and/or negative relationships are more likely to consume alcohol compared to individuals with lower levels of strain. In particular, this study proposes to examine how parental attachment, parental monitoring, time spent with family, parents’ religiosity, family economic strain, and negative life events in the family predict alcohol consumption among adolescents in Turkey. 2008 Youth in Europe (YIE) project data is used in the study. In general, the results indicate that social bonding and strain factors have significant effects on the adolescents’ alcohol consumption patterns. These findings will help to inform prevention programs aimed at reducing adolescent alcohol risk behaviors by explaining the importance of family relationships.

Guidelines for Greening (Renovation) of Existing Homes
This Thesis is aimed at evaluating the options of renovation for an existing residential building to make it more energy efficient. The various aspects in the basic structures of residential homes are discussed in order to help the user identify the areas of the house for which renovation is required to improve the energy efficiency of the building. These aspects include doors, roof and wall in addition to various systems of electrical wiring, mechanical systems of ventilation, heating and cooling and plumbing systems for the efficient flow of water throughout the house. The renovation options have been described in detail to provide as many possibilities to the user as possible. The building taken for renovation is a 1953 suburban home which has been awarded the honor of being the first building to be labeled as Zero Energy Home in its vicinity. This has made the home so efficient that its expenditure of energy has become equivalent to its energy generation, therefore, cancelling each other out and creating an estimate of zero energy.

Characterizing the Molecular Changes of Austrofundulus limnaeus As It Develops Towards and Enters Diapause II
Austrofundulus limnaeus is a species of annual killifish which inhabits ephemeral ponds in South America. The species is able to survive seasonally desiccating ponds due to their ability to produce robust embryos. The embryos of this species are capable of entering a developmental arrest, termed diapause II, which precedes the onset of drought. While in this arrested state embryos exhibit the greatest tolerance to anoxia of any characterized vertebrate at 25ºC. Furthermore, when raised at 30ºC, embryos escape the entrance to diapause II and go on to develop directly. Currently, little is known about the molecular mechanisms which induce and maintain this developmentally arrested state. In this study I have developed methods to analyze changes in histone modifications in the context of diapause II. Histone modifications were chosen due to their extreme conservation and well characterized role as modulators of gene expression in other systems. Results utilizing adapted immunobased assays show significant changes in the global amount of H3S10P, H3K27me and H3K4me, as the embryos progress from early embryogenesis through the exit of diapause. Additionally, it is revealed that there exists a degree of phenotypic plasticity with regards to the entrance into diapause II which is modulated by the environment …

A Teaching Guide for Debussy and Ravel: Technical and Stylistic Applications for Korean Piano Teachers
Most Korean students study very little French music during their pre-college years. A survey of ten Korean piano professors as well as an investigation into the annual set repertoire from universities, music high schools, middle schools and national competitions in Korea show that French repertoire appears very seldom on the list of required repertoire. Therefore, it is easy for Korean students to neglect French piano music. By the time students reach undergraduate or graduate school and are required to play the music of Debussy and Ravel for the first time, they find themselves at a serious disadvantage. The purpose of this paper is to provide a pedagogical guide for Korean teachers who wish to offer their beginning, middle school and high school students a good foundation in the style of French piano music. This syllabus will introduce a series of French piano pieces, from Couperin and Rameau as well as Chaminade and Fauré to the easier pieces of Debussy and Ravel, which will lead to the ultimate goal of interpreting aspects of French tone, style, technique, and cultural context involved in the eventual successful performance of the more advanced pieces of Debussy and Ravel, which are the bedrock of French …

Reliability Generalization: a Systematic Review and Evaluation of Meta-analytic Methodology and Reporting Practice
Reliability generalization (RG) is a method for meta-analysis of reliability coefficients to estimate average score reliability across studies, determine variation in reliability, and identify study-level moderator variables influencing score reliability. A total of 107 peer-reviewed RG studies published from 1998 to 2013 were systematically reviewed to characterize the meta-analytic methods employed and to evaluate quality of reporting practice against standards for transparency in meta-analysis reporting. Most commonly, RG studies meta-analyzed alpha coefficients, which were synthesized using an unweighted, fixed-effects model applied to untransformed coefficients. Moderator analyses most frequently included multiple regression and bivariate correlations employing a fixed-effects model on untransformed, unweighted coefficients. Based on a unit-weighted scoring system, mean reporting quality for RG studies was statistically less than that for a comparison study of 198 meta-analyses in the organizational sciences across 42 indicators; however, means were not statistically significantly different between the two studies when evaluating reporting quality on 18 indicators deemed essential to ethical reporting practice in meta-analyses. Since its inception a wide variety of statistical methods have been applied to RG, and meta-analysis of reliability coefficients has extended to fields outside of psychological measurement, such as medicine and business. A set of guidelines for conducting and reporting RG …

Migration Information Gathering by Mexican-origin Immigrants in the Pre-migration Phase
U.S. immigration procedures are complex and may elude the average individual seeking admission to the United States. Understanding this, the current study investigates how information resources are used by potential migrants to learn about the migratory process. Using a mixed-methods approach, I interviewed 30 Mexican immigrants with unauthorized immigration experience about the process of gathering migration information in the pre-migration phase. Qualitative data were coded using seven themes generated from the primary research questions, including: Information Resources, Resources Used During Migration, Motivation for Migration, Method of Migration, Lack of Information/Misinformation, Types of Help and Types of Information. Findings suggest that the factors motivating migrants to come to the U.S. are combined in complex ways and lack of information about legal alternatives to unauthorized migration is an important factor influencing method of migration. Also, while access to new information resources is increasing, these resources are not being tapped for migration information.

Montesquieu, Diversity, and the American Constitutional Debate
It has become something of a cliché for contemporary scholars to assert that Madison turned Montesquieu on his head and thereafter give little thought to the Frenchman’s theory that republics must remain limited in territorial size. Madison did indeed present a formidable challenge to Montesquieu’s theory, but I will demonstrate in this dissertation that the authors of the Federalist Papers arrived at the extended sphere by following a theoretical pathway already cemented by the French philosopher. I will also show that Madison’s “practical sphere” ultimately concedes to Montesquieu that excessive territorial size and high levels of heterogeneity will overwhelm the citizens of a republic and enable the few to oppress the many. The importance of this dissertation is its finding that the principal mechanism devised by the Federalists for dealing with factions—the enlargement of the sphere—was crafted specifically for the purpose of moderating interests, classes, and sects within an otherwise relatively homogeneous nation. Consequently, the diverse republic that is America today may be exposed to the existential threat anticipated by Montesquieu’s theory of size—the plutocratic oppression of society by an elite class that employs the strategy of divide et impera.

Exploring Student Learning on a Short-term, Faculty-led Study Abroad Course Through a Student Development Lens
Embarking on a study abroad experience is thought to be a transformational experience for students, and previous researchers have tended to find that the potential benefits of study abroad experiences, including greater conceptual and behavioral intercultural competence, are greater with longer periods abroad. The purpose of this study was to create an intentional learning experience for students who embarked on a short-term study abroad in rural areas of China and to apply faculty intervention of a student development approach to student learning to create a high-impact learning environment for students centered on a service-learning project. This qualitative study gathered primary data from students and instructors during the course through a collection of observation and field notes, student journals, pre- and post-construct tests, and final presentation. Follow-up interviews were conducted 10 months after course completion. Six students participated in this course and study who were from a variety of disciplines and classifications. Five students were female; one was male. Four students were undergraduates; two were graduate students. Student ethnicities included three Caucasians and African American, along with two international students from Mexico and Iran. Key outcomes of this study were that when short-term study abroad faculty members applied creative interventions, students …
