description: The results of analytical measurements performed with solid-sampling techniques are affected by the distribution of the analytes within the matrix. The effect becomes significant in case of determination of trace elements in small subsamples. In this framework we propose a measurement model based on Instrumental Neutron Activation Analysis to determine the relative variability of the amount of an analyte among subsamples of a material. The measurement uncertainty is evaluated and includes the counting statistics, the full-energy gamma peak efficiency and the spatial gradient of the neutron flux at the irradiation position. The data we obtained in a neutron activation experiment and showing the relative variability of As, Au, Ir, Sb and W among subsamples of a highly pure Rh foil are also presented.

description: Objective

Anxiety sensitivity—fear of the negative social, physical, or cognitive consequences of anxiety related sensations—has been linked to cardiovascular disease and adverse cardiovascular health behaviors. Medication nonadherence may account for this association. We examined whether anxiety sensitivity was independently associated with objectively measured medication nonadherence in a multi-ethnic primary care sample.

Methods

Eighty-eight patients with uncontrolled hypertension completed the Anxiety Sensitivity Index and had their adherence to blood pressure (BP) medications measured during the interval between two primary care visits using an electronic pillbox (MedSignals®). Multivariable Poisson regressions were conducted to determine the relative risks of medication nonadherence associated with anxiety sensitivity after adjustment for age, gender, Hispanic/Latino ethnicity, education, total number of prescribed medications, and depressive and posttraumatic stress disorder (PTSD) symptoms.

Results

Nearly twice as many patients with high anxiety sensitivity were nonadherent to BP medications compared to patients with low anxiety sensitivity (65.0% vs. 36.8%; p = 0.03). Patients with high anxiety sensitivity had higher relative risks of medication nonadherence than their low anxiety sensitivity counterparts (adjusted relative risk [RR] = 1.76; 95% CI: 1.03–3.03).

Conclusions

In this first study of the association between anxiety sensitivity and medication adherence, we found that high anxiety sensitivity was strongly associated with BP medication nonadherence, even after adjustment for known confounders. Our results suggest that teaching patients who have uncontrolled hypertension adaptive strategies to manage their anxiety sensitivity may help improve their medication adherence, and thereby lower their cardiovascular risk.

description: This article considers the larger material and political contexts of the 1636 murder of John Oldham aboard his boat by Narragansett-allied Indians, an event that was one of the causes of the 1636–38 Pequot War. Oldham’s slaying illustrates how the contested region between New England and New Netherland was a “saltwater frontier” where the primary arena of cross-cultural exchange was the coastline and its nearshore waters, not the land. Natives and colonists relied on each other’s maritime technologies and knowledge. At the same time the tricky logistics of their encounters made this zone uniquely perilous. Oldham’s Indian killers were also motivated by an intense trade rivalry between Native powers. A series of events caused them to harbor suspicions of Oldham and inspired them to commit small-scale piracy during his murder. The article concludes that the ensuing Pequot War should be seen as a naval war that turned into terrestrial war, reflecting the English desire to shift the frontier off the water and onto dry land.

description: The results observed in experiment 3 and 4 suggest that pre-cueing manipulations might modulate the social component, leading to the observed variations with eye-gaze targets. Moreover, the presence of placeholders may further influence these manipulations in this particular setting, potentially impacting the congruency effect. Therefore we decided to conduct two follow-up experiments, one for each pre-cue type, and adding a placeholder manipulation (present vs. absent).

description: Here we report on a novel chemical route to synthesize homogenous cobalt doped titanate nanotubes (CoTNT), using an amorphous Co-doped precursor. The influence of the synthesis temperature, autoclave dwell time and metal doping on the structural and microstructural as well as on the optical properties of the synthesized titanate nanotubes is studied and discussed. The optical band gaps of the CoTNT samples are red shifted in comparison with the values determined for the undoped samples, such red shifts bringing the absorption edge of the CoTNT samples into the visible region. CoTNT materials also demonstrate particular high adsorption ability for methylene blue, the amount of the adsorbed dye being higher than the one predictable for a monolayer formation. This suggests the possibility of intercalation of the dye molecule between the TiO6 layers of the TNT structure. It is also shown that the methylene blue sensitized Co-doped nanostructures are highly stable under UV radiation and present a strong and broad absorption in the visible region.

description: Case Study Research in Applied Linguistics offers a detailed foray into all aspects of the role of the case study: the text defines terms related to this type of research, provides historical background on the method, and explains the process of performing and reporting case studies. Such a comprehensive introduction addresses a gap in the literature. Many research methods texts provide overviews of different kinds of quantitative and qualitative research often utilized in the field of applied linguistics, including correlational research, introspective research, and in-class observations (e.g., Brown & Rogers, 2002; Dörnyei, 2007). Few, however, focus exclusively on case study research, lacking examination of the often painstaking process case studies entail. While the book’s scope is broad, Duff’s purposes are clear and concise from the outset: 1) to delineate the methodological foundations of case study research, 2) to present and examine seminal case studies in the area of second language (L2) development and teaching, and 3) to demystify the process of case study research from conception to publication. As these goals suggest, the book intends to offer the necessary information and sound advice to budding researchers in applied linguistics on both the graduate and undergraduate level.

title: Gustav Mahler's Symphonies and the Search for Identity
Creators: name: Hailes, Brian
Publisher: name: University of Massachusetts Amherst
Year: 2022

description: Throughout his life Gustav Mahler (1860-1911) was aware of his role as an outsider and had a deeply conflicted view of his identity. The challenges he faced as a Jew in an overwhelmingly Christian and increasingly anti-Semitic Central Europe, as a German speaker in predominantly Czech speaking Bohemia and Moravia, as a Czech in the Austrian empire, and as an Austrian in a highly militarized but rapidly declining empire in the face of increasing pan-German nationalism, all contributed to this status. At the same time, his diverse early background provided a rich variety of musical experience, leading to an openness to musical influences that would accompany him throughout his career.
Mahler was one of the first German modernists. His approach to the symphony was unique, revolutionary and widely misunderstood. By stretching the boundaries of structure and content with references to childhood, nature and the sounds and images of everyday life, through the deliberate, unsettling juxtaposition of the banal and the sublime, and through the use of voice and text, he used the symphony as a vehicle for personal reflection and exploration. Mahler’s primary forms of composition were Lieder and symphonies, and as his career progressed the two became inexorably intertwined. His music has been described as Weltanschauungsmusik - music that expresses a world outlook. Driven by a desire to engage with the symphonic tradition, his works included the first non-programmatic choral symphonies since Beethoven.
This study focuses on particular aspects of Mahler’s compositional style to demonstrate his continuous search for identity: the references to and quotations from his own songs, from the works of other composers, and from sources such as Jewish/Central European folk music; the rhythmic influence of dances and marches as social references and indicators; the use of non-traditional instrumentation, timbre and sound effects to provide emphasis, coloration and contrast; and the symphonic use of vocal music to explore religious and philosophical beliefs.

description: As the construct of formulaic language gains sway in language acquisition theory and pedagogy, the number of publications on corresponding theoretical treatises and empirical research has also been on the grow. Formulaic Language: Pushing the Boundaries is the most recent monograph of one of the field’s authoritative figures, Alison Wray. Formulaic expressions or sequences, in simple terms, are linguistic units composed of multiple words. According to Sinclair (1991), they are subsumed under a model of language processing called the Idiom Principle, which postulates that “a language user has available to him or her a large number of semi-preconstructed phrases that constitute single choices” (p. 110). These single, multi-word choices in effect are mediators for human language competence and idiomatic language use.

description: We consider the question of giving an upper bound for the first nontrivial eigenvalue of the Wentzell-Laplace operator of a domain $Ω$, involving only geometrical informations. We provide such an upper bound, by generalizing Brock's inequality concerning Steklov eigenvalues, and we conjecture that balls maximize the Wentzell eigenvalue, in a suitable class of domains, which would improve our bound. To support this conjecture, we prove that balls are critical domains for the Wentzell eigenvalue, in any dimension, and that they are local maximizers in dimension 2 and 3, using an order two sensitivity analysis. We also provide some numerical evidence.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

description: The transverse single-spin asymmetry, AN, for neutral pion production at xF ≈ 0.0 for 1 < pT < 5 GeV/c from polarized proton-proton interactions at √s = 200 GeV has been presented. The measurement is in a kinematic regime where the theoretical framework of perturbative QCD has been demonstrated to describe the polarization-averaged cross sections for neutral pions and charged hadrons well for pT > 1.5 GeV/c. A pQCD framework is expected to be applicable in the interpretation of the polarized results down to similar transverse momentum values.

description: We perform a model independent reconstruction of the cosmic expansion rate based on type Ia supernova data. Using the Union 2.1 data set, we show that the Hubble parameter behaviour allowed by the data without making any hypothesis about cosmological model or underlying gravity theory is consistent with a flat LCDM universe having H_0 = 70.43 +- 0.33 and Omega_m=0.297 +- 0.020, weakly dependent on the choice of initial scatter matrix. This is in closer agreement with the recently released Planck results (H_0 = 67.3 +- 1.2, Omega_m = 0.314 +- 0.020) than other standard analyses based on type Ia supernova data. We argue this might be an indication that, in order to tackle subtle deviations from the standard cosmological model present in type Ia supernova data, it is mandatory to go beyond parametrized approaches.

title: Theory and Analysis of Backprojection Processing for Interferometric SAR
Creators: name: Closa Tarres, Marc
Publisher: name: University of Massachusetts Amherst
Year: 2022

description: Synthetic Aperture Radar (SAR) is a well-known radar technique widely used for 2D and 3D imaging since the 1960s. SAR systems offer all-weather, day and night, high-resolution imaging by using the motion of the antenna over the target of interest. By later use of signal processing techniques, the received echoes can be put back together using precise knowledge of the system location and geometry to obtain the distinct high-resolution SAR imagery.
Moreover, when the system is equipped with multiple antennas, topography and topographic changes in the region of interest can be inferred using interferometric techniques.
The Microwave Remote Sensing Laboratory (MIRSL) has developed multiple Synthetic Aperture Radar Systems over the past years. These systems have been tested in different data collection campaigns. For instance, the Ku-band system was used in the Trail Valley Creek region in Canada during the 2018-19 snow season. In addition, data processing capabilities were also developed in the past years allowing MIRSL to obtain their own Synthetic Aperture Radar products without any third-party organization interaction.
The scope of this thesis is to develop a tool to provide data validation and troubleshooting resources to the data acquired and processed using the radar systems and processing tools from MIRSL. This can be achieved by simulating ideal radar data and later running it through the processing software developed by the laboratory.
The simulator can generate artificial raw data from a wide range of input variables that may have an impact on the acquisition of real radar data. The platform attitude, miss-calibrations of the system, or even processing errors may be sources of important errors when obtaining SAR images. For this reason, this simulator can be used to generate raw data products in a controlled environment for further data validation and plausible error troubleshooting.

description: The velocity field of the M87 jet from milli-arcsecond (mas) to arcsecond scales is extensively investigated together with new radio images taken by EVN observations. We detected proper motions of components located at between 160 mas from the core and the HST-1 complex for the first time. Newly derived velocity fields exhibits a systematic increase from sub-to-superluminal speed in the upstream of HST-1. If we assume that the observed velocities reflect the bulk flow, we here suggest that the M87 jet may be gradually accelerated through a distance of 10^6 times of the Schwarzschild radius of the supermassive black hole. The acceleration zone is co-spatial with the jet parabolic region, which is interpreted as the collimation zone of the jet (Asada & Nakamura 2012). The acceleration and collimation take place simultaneously, which we suggest a characteristic of magnetohydrodynamic flows. Distribution of the velocity field has a peak at HST-1, which is considered as the site of over-collimation, and shows a deceleration downstream of HST-1 where the jet is conical. Our interpretation of the velocity map in the M87 jet gives a hypothesis in AGNs that the acceleration and collimation zone of relativistic jets extends over the whole scale within the sphere of influence of the supermassive black hole.

description: The nature of second language (L2) reading ability is extremely complex and its components are yet to be agreed upon. The current study hypothesized that L2 reading ability consists of (1) reading for literal meaning (LIT), (2) reading for implied meaning with endophoric reference (IMP-EN), and (3) reading for implied meaning with exophoric reference (IMP-EX). In addition, different reading passages were assumed to affect test performance in varying degrees. Participants were 298 incoming students to an adult English as a second language (ESL) program. They took a reading placement test consisting of four reading passages and 30 items. Participants’ reading scores were analyzed using the confirmatory factor analysis (CFA) approach in structural equation modeling (SEM). Findings suggest that L2 reading ability consists of the three constructs of LIT, IMP-EN, and IMP-EX. Moreover, the three reading constructs are on a continuum with LIT having the most direct relationship between the text and the response, while IMP-EX having the most indirect relationship. However, reading passages did not have a significant influence on test performance.

title: Local Nanomechanical Variations of Cold-sprayed Tantalum Coatings
Creators: name: Chowdhury, Dhrubajyoti
Publisher: name: University of Massachusetts Amherst
Year: 2022

description: Cold spray (CS) deposition of metals is a process involving deposition of materials in the solid or semi-solid state. It also has lower operating temperatures, and oxidation is greatly reduced in the process. The process is beneficial for refractory metals, such as tantalum, which are tough and difficult to machine. The interface between the CS powder and the substrate is the most important region for the study of mechanical properties as it is where the bonding process occurs first; studying mechanical properties at the nanoscale will give us a better idea of the mechanical properties of the coated surface. The present work investigates multiple-sprayed conventional and low-hydrogen treated tantalum powders on stainless steel substrates and also single-sprayed nitrogen-treated tantalum powders on aluminum substrate using Atomic force microscopy (AFM). It also discusses the effects of topography on the local changes in modulus.
AFM is an instrument that measures the site-specific property of the sample. In this work, the local Young's modulus is studied using force-distance curves. Calibration of the AFM cantilever and the photodetector used to measure the cantilever, is a vital step before the actual process. The conventional method of calibration can cause damage to the tip as it arbitrarily penetrates into the sample creating a cantilever deflection vs. tip penetration curve, giving the sensitivity of the photodetector.
AFM is highly dependent on topographical features as the cantilever tip-sample interaction can vary, causing variations in the property mapped. This work, however uses a non-contact method of calibration which saves the cantilever tip from potential damages, saving the results from the detrimental effects of tip topography. The work also discusses the effects of local sample deformation and volume of tip-surface contact on local changes in Young's modulus at the interface of coating and substrate.
This work uses Electron micro-probe analysis (EPMA) to show the presence of oxides at the interface. The presence of oxides changes the bond energy as compared to a pure tantalum bond, ultimately affecting the local modulus mapped using AFM. The effect of oxides on the local modulus at the coating-substrate interface is theoretically discussed.

description: Today’s world is vastly impacted by the effects of immigration and globalization. The cultural diversity in the student population in the United States continues to grow steadily along with the immigrant population. Although there is a large body of research that is concerned with culturally responsive teaching in music education, preservice teacher preparation to address and serve diverse communities, as well as issues of recruitment of diverse educators, there is a gap in the literature when it comes to the perspectives of international music educators in the United States. Researchers have provided information on diverse student populations and resources for music educators of non-diverse backgrounds, but the voices of international music teachers have not yet been heard. International music teachers could possess unique insights, and might be able to relate to students in a way that most music teachers cannot. They are also equipped with different experiences due to their own diverse backgrounds. In this study, interviews of international music teachers provide a conduit to gain understanding of their experiences, reflections and suggestions in order to provide an unexplored perspective for the field of music education.

description: Given the general failure experienced by adults when attempting to learn a second or foreign language, many have hypothesized that a critical period exists for the domain of language learning. Supporters of the Critical Period Hypothesis (CPH) contend that language learning, which takes place outside of this critical period (roughly defined as ending sometime around puberty), will inevitably be marked by non-native like features. In opposition to this position, several researches have postulated that, although rare, nativelike proficiency in a second language is in fact possible for adult learners. Still others, in light of the robust debate and research both supporting and challenging the CPH, have reconceptualized their views regarding a possible critical period for language learning, claiming that in combination with age of exposure, sociological, psychological, and physiological factors must also be considered when determining the factors that facilitate and debilitate language acquisition. In this paper, a review of literature describing the support, challenges, and reconceptualizations of the CPH is provided.

description: In this paper, we propose two protocols for generating super-resolving \textit{single-photon} path-entangled states from general maximally path-entangled N00N states. We also show that both protocols generate the desired state with different probabilities depending on the type of detectors being used. Such super-resolving single-photon path-entangled states preserve high resolving power but lack the requirement of a multi-photon absorbing resist, which makes this state a perfect candidate for quantum lithography.

title: Foaming Properties of Dilute Pea Protein Solutions
Creators: name: Bao, Jiani
Publisher: name: University of Massachusetts Amherst

description: Plant-derived protein such as pea protein is a promising replacement for animal protein and is becoming popular in recent years because of its high nutritional value and potential reduction of environmental footprint. However, the increasing demand for plant-derived proteins is accompanied by the increase of wastes during protein processing such as wastewater containing dilute protein content, which may raise the cost for the downstream processing. Therefore, there is an emerging need to develop novel processing strategies to reduce waste while valorizing useful ingredients. Several researchers suggest that foam fractionation technology can be a viable approach to extract and concentrate protein from dilute wastewater effluent. This technology has already been applied to the chemical and food industry for the extraction of surfactant and animal proteins from wastewater. To design and apply foam fractionation to the plant-derived protein industry, fundamental knowledge on foaming properties of dilute plant-derived protein solution is needed and is currently lacking. Therefore, the objective of this thesis is to advance a fundamental understanding of the foaming properties of dilute pea protein solutions (protein concentration ≤ 1wt%). To achieve the objective, a multiscale approach is used, which is comprised of a detailed investigation of both bulk and interfacial properties of pea protein solutions and foaming properties such as foaming capacity and stability with the help of bubble structure and foam volume kinetics. The focus of this thesis is on the effect of protein concentration. Results demonstrate that protein adsorption kinetics can be characterized by four distinctive regimes: lag phase, diffusion-limited regime, transitional regime, and conformation change regime, which are highly dependent on the protein concentration. However, apparent viscosity is less affected by the protein concentration. Results also show that depending on the protein concentration, two regimes can be distinguished for foam capacity and foam stability. For the first time, these regimes can be rationalized by contrasting characteristics times of protein adsorption kinetics and processing time scale – residence time of bubbles during the foam formation.  New findings from this fundamental research will shed light on the control and optimization of foaming properties of plant-derived protein solutions for applications ranging from food processing design to food product development.

description: The significance of input, namely meaning-bearing linguistic instances of the target language (TL) (VanPatten, 1996), in accounting for how learners create second language (L2) grammars has long been established (Gass, 1997). Krashen (1985), in his Input Hypothesis, even argues that the sheer provision of abundant comprehensible input would be “necessary and sufficient” for second language acquisition (SLA). In light of such characteristics as “lack of success” and “the importance of instruction” in Bley-Vroman’s (1989) Fundamental Difference Hypothesis vis-à-vis adult L2 learners, however, it appears that manipulating aspects of learning conditions may facilitate L2 grammar acquisition. Some researchers (e.g., Sanz and Morgan-Short, 2005) suggest that external manipulation of input through textual (Jourdenais, Ota, Stauffer, Boyson, & Doughty, 1995) or prosodic (Leeman, 2003) enhancement, or even input flood (Trahey & White, 1993) might induce internal processing, considering that the target forms are made more salient and are thus more likely to be detected by the learner. Others (e.g., Chaudron, 1983; Corder, 1967; Faerch & Kasper, 1980; Krashen, 1982; Sharwood Smith, 1986; VanPatten, 1996, 2002a, 2004a, 2007), while acknowledging the difficulty of controlling and measuring L2 processing, still see value in theorizing about the learner’s internal language acquisition mechanism to make sense of the manner input processing (IP) works, i.e., what kind of L2 input gets converted to intake and the rationale behind it.

description: This dissertation presents the measurement of electrons from heavy flavor decays in proton + proton collisions at RHIC at colli­sion energy √s = 200 GeV over a wide range of transverse moment (0.4 < pr < 5 GeV/c). Two independent analysis techniques of signal extraction were performed. This is the first measure­ment of the Open Charm cross section at this collision energy and it is an important baseline measurement for comparison with nucleus + nucleus collisions.

title: Investigating Bilingual AAC Practices in Bilingual Communities
Creators: name: Salisbury, Johanna
Publisher: name: University of Massachusetts Amherst
Year: 2022

description: This thesis investigates best practices for teaching and supporting bilingual augmentative and alternative communication (AAC) users as they develop their communication skills. Although there are guidelines that inform best practices for teaching and supporting bilingual AAC users, there is very little information on what these practices look like. This thesis investigates the techniques and strategies that bilingual speech-language pathologists (SLPs) who practice in Catalunya, a bilingual community in northeastern Spain, use to evaluate, teach, and support people who use pictogram-based AAC modalities to communicate.

To do this, six SLPs who practice in Catalunya participated in interviews regarding their practices when teaching bilingual AAC users. These interviews were analyzed thematically, based on an iterative, inductive coding process. Analysis revealed that most bilingual AAC users have access to an AAC system in only one language of the community. This may reflect a monolingual mindset (Tonsing & Soto, 2020), and limits the opportunities for engagement with both the larger community, and the individuals’ home communities. This is particularly true for those who speak a language other than those of the community with their families. Despite this, AAC users seem to understand both languages, develop bilingual identities, and “feel bilingual.” Additionally, despite the lack of access to multilingual AAC systems, professionals employ practices that show respect for the home language, whether it is Castilian Spanish, Catalan, or another language. The results suggest that the monolingual mindset is a deeply-ingrained part of educational and therapeutic systems in both monolingual and bilingual communities, even when individual practitioners respect and value their clients’ home language(s) and bilingual identities.
Coherence Factors Beyond the BCS Expressions -- A Derivation

description: We present a derivation of a previously announced result for matrix elements between exact eigenstates of the pairing Hamiltnonian. Our results, which generalize the well known BCS (Bardeen-Cooper-Schrieffer) expressions for what is known as 'coherence factors', are derived based on the Slavnov formula for overlaps between Bethe-ansatz states, thus making use of the known connection between the exact diagonalization of the BCS Hamiltonian, due to Richardson, and the algebraic Bethe ansatz. The resulting formula has a compact form after a suitable parameterization of the Energy plane. Although we apply our method here to the pairing Hamiltonian, it may be adjusted to study what is termed the 'Sutherland limit' for exactly solvable models, namely where a macroscopic number of rapidities form a large string.
