La Institución Pública es un organismo encargado de la recaudación en el Perú vinculado al Ministerio de Economía y Finanzas, y tiene como Misión transformarse en la administración tributaria y aduanera más exitosa, moderna y respetada de la región. Para eso desde hace algunos años la institución ha comenzado a lanzar iniciativas de proyectos de software que utilicen cloud computing, para que de esta forma puedan trabajar de manera más eficiente la gestión y compra de infraestructura, así como poder atender la demanda creciente de servicios digitales solicitados por los contribuyentes. La presente tesis analizó la forma de cómo la Institución Pública fue adoptando cloud computing en sus proyectos de software, y como esta adopción puede ser mejorada al contar con un marco de trabajo que le permita tener pautas de cómo lanzar iniciativas que involucren en su desarrollo el uso de cloud como base tecnológica, y como esto debe estar alineada a la estrategia de crecimiento de servicios digitales que la Institución Pública desea ir cubriendo poco a poco para mejora su servicio hacia los contribuyentes. / The Public Organization is an institution in charge of tax collection in Peru, and linked to the Ministry of Economy and Finance, and has as its main mission to become the most successful, modern and respected tax and customs administration in the region. For this reason, for some years ago, the institution has begun to launch software project initiatives that use cloud computing, so that they can work more efficiently in the management and purchase of infrastructure, as well as being able to meet the growing demand for digital services. requested by taxpayers The current thesis analyzed how the Public Organization was adopting cloud computing in its software projects, and how this adoption can be improved, by having a framework that allows it to have guidelines on how to launch initiatives that involve in its development the use of Cloud as a technology base, and how this should be aligned with the digital services growth strategy that the Public Organization wishes to gradually cover to improve its service to taxpayers. / Trabajo de investigación

This thesis is a corpus and narrative-based description of how the lexical aspect of predicates with the switch reference same subject (SS) suffix -ʃa affects the meaning of utterances in Pastaza Kichwa (PK), a Quechuan dialect spoken in Amazonian Ecuador. The main purpose of this thesis is to describe how verb chains that use -ʃa are affected by lexical aspect. The secondary purpose is to compare these uses with current grammars, and determine whether there are more uses than are currently proposed in the most recent grammar of PK. The most recent grammar of PK lists the functions of the coreference -ʃa as being indicative of simultaneous and sequential actions (Nuckolls & Swanson, 2020). I argue that not only does the lexical aspect of predicates in a -ʃa verb chain determine simultaneity and sequentiality, but there is a third category of habitual action that is at least partially determined by the lexical aspect of -ʃa verb chains. After introducing the concept of switch reference, I introduce the concept of lexical aspect. From there I discuss my methodology and analysis, which is based on Van Valin’s (2006) tests and categories of lexical aspect. My analysis is composed of text examples from the Quechua Realwords (QRW) corpus (Nuckolls, 2021), and a PK narrative about Noah and the Flood. These are supplemented by examples from the Corpus of Pastaza Kichwa (CoPK) compiled by Rice (2018). These examples are used to demonstrate the lexical aspect of each verb in a -ʃa verb chain.

Topic modeling is an effective tool for analyzing the thematic content of large collections of text. However, traditional probabilistic topic modeling is limited to a small number of topics (typically no more than hundreds). We introduce fine-grained topic models, which have large numbers of nuanced and specific topics. We demonstrate that fine-grained topic models enable use cases not currently possible with current topic modeling techniques, including an automatic cross-referencing task in which short passages of text are linked to other topically related passages. We do so by leveraging anchor methods, a recent class of topic model based on non-negative matrix factorization in which each topic is anchored by a single word. We explore extensions of the anchor algorithm, including tandem anchors, which relaxes the restriction that anchors be formed of single words. By doing so, we are able to produce anchor-based topic models with thousands of fine-grained topics. We also develop metrics for evaluating token level topic assignments and use those metrics to improve the accuracy of fine-grained topic models.

Book Summary: Tailor your institution’s approach to transfer students using this collection’s creative ideas for orientations, library instruction, partnerships with like-minded campus groups, and other initiatives. Higher ed admission teams are aggressively recruiting transfers—and they’re finding success. According to the National Student Clearinghouse, about 38 percent of all students in higher ed in the United States have transferred at least once. If you don’t include transfer students in your outreach and instruction planning, you’re missing a significant portion of the student body. However, to meet the needs of this population requires academic libraries to rethink assumptions about incoming students. Gathering 17 case studies, the editors present a rich and nuanced picture of academic library services to transfer students that will empower you to achieve transfer student success. You will learn about organizing around the strengths of transfer students; applying design thinking to ease transfer students’ “culture shock”; using autoethnography narratives to better understand the transfer student experience; revamping a transfer student success course by incorporating student reflections; building a campus network of transfer student support and information sharing; partnering with military and veteran support groups on campus; recruiting transfer students to a campus peer mentor program; serving students in health sciences bridge programs; building connections with a fiction book club; and creating personal librarian programs or librarian positions dedicated to transfer students.

SUMMARY: Published guidelines for distance learning library services provide a framework for distance education librarians to use in planning services for off-campus students. Other literature in the arena of distance education librarianship provides concrete examples of how reference services have been offered in real settings. This paper attempts to synthesize these two types of literature in order to offer models of reference service for distance learners.

The object of this investigation is to determine whether two aspects of reference group orientation, 1) multiplicity and 2) structural variation, are possible indicators of ethnocentrism. Most of the thesis is devoted to a theoretical formulation in which reference group orientation and ethnocentrism are placed in a peroeptual framework. Reference group orientation is defined as a person's use of a frame of reference that is formed through adoption of a reference group's perspective. Ethnocentrism is defined as a person's use of a frame of reference that keeps him from accepting the viability of other cultural frames of reference. The acceptance of the viability of other cultural frames of reference is defined as ethnorelativism. A flexible formation of cultural identity creates the conditions for a large number (relatively high multiplicity) and broad diversity (relatively high structural variation) of reference group orientations. It is hypothesized that those people who are aware of higher multiplicity and higher structural variation of reference group orientations will be more likely to accept the viability of other cultural frames of reference.

Accurate determination of the surface enhanced Raman scattering (SERS) enhancement factor (EF) is critically important for a fundamental understanding of the SERS phenomenon. Experimental quantification of SERS EFs is challenging. A series of instrument-, analyte-, and SERS-substrate related issues can affect the SERS intensity and thus compromise the reliability of the measured SERS EFs. This dissertation presents a series of computational and experimental studies that enhance the quantitative understanding of the SERS signal variation and identify ways to enhance the reliability of the SERS EF determination. Chapter I presents an overview of works described in this dissertation. The gold nanoparticle (AuNP) inner filter effect on SERS measurements is demonstrated in Chapter II. Using dithiopurine and ethanol as model analytes, we demonstrate that the nanoparticle will modify the analytes’ Raman signal through two competitive mechanisms: enhancing the Raman signal of the analyte on the nanoparticle surface through electromagnetic enhancement, and attenuating the analyte Raman signal through photon extinction. The significance of the AuNP inner filter effect is quantitatively evaluated using ethanol as the internal reference. A solvent internal reference method is presented in Chapter III for quantifying the SERS EFs of analytes adsorbed onto AuNPs and AgNPs. One of the key findings is that while an analyte’s SERS EF varies significantly as a function of nanoparticle aggregation, its peak SERS EF depends only on the types and sizes of nanoparticles, but not on experimental conditions including concentrations of analyte, nanoparticle, and aggregation reagent. Chapter IV presents a SERS internal reference method for the determination of the resonance Raman EFs in the SERS study of rhodamine 6G (R6G) adsorbed onto AuNPs and AgNPs. The most striking finding is that the AgNP binding reduces, instead of enhancing, the R6G resonance enhancement. Finally, the wavelength-dependent correlation between UV-vis intensities and SERS EFs of aggregated AuNPs and AgNPs were investigated under three fixed excitation wavelengths (532, 632, and 785 nm). The nanoparticle UV-vis intensity is an excellent indicator for identifying the optimal aggregation state for AgNP-based SERS acquisitions under each of the three excitation wavelengths and for the AuNP-based SERS under a 632 nm excitation.
