Quantum chemistry for spectroscopy : a tale of three spins (S = 0, 1/2, and 1)
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemistry, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Vita.Includes bibliographical references (p. 193-203).Three special topics in the field of molecular spectroscopy are investigated using a variety of computational techniques. First, large-amplitude vibrational motions on ground-state singlet (S0) potential energy surfaces are analyzed for both the acetylene/vinylidene and the HCN/HNC isomerization systems. Electronic properties such as electric dipole moments and nuclear quadrupole coupling constants are used as diagnostic markers of progress along the isomerization path. Second, the topic of electronically excited triplet states and their relevance to doorway-mediated intersystem crossing for acetylene is considered. A new diabatic characterization of the third triplet electronic state, T3, enables a vibrational analysis of data obtained from current and past experiments. The last part of this thesis reviews the techniques and ideas of electron-molecule collisions relevant to Rydberg states of diatomic molecules. Previously developed and current methods of treating the excited Rydberg electron are evaluated and extended. Each of these three topics in molecular spectroscopy is studied using ab initio approaches coupled with experimental observations or chemically intuitive models. The unique combination of quantum chemistry and spectroscopy stimulates further developments in both theory and experiment.by Bryan Matthew Wong.Ph.D
The evaluation of a metacognition education intervention through dialogic teaching for the promotion of self-regulated learning of Deaf and hard of hearing students in Deaf schools
No full textA majority of one's education is conducted through informal learning. With the increase in digitization and the use of the Internet, informal learning is becoming a facet of formal learning and adult learning. Learning strategies can be employed to aid students and learners toward a higher degree of achievement in academic or workplace goals. These strategies include metacognition, self-regulated learning, and self-directed learning. These tools are nested entities in that strong metacognitive skills and awareness are important to have strong self-regulated learning skills and effective self-regulated learners are effective self-directed learners. This would imply that in order to have successful lifelong learning, metacognitive strategies are a necessity. Deaf and hard of hearing people have issues employing metacognitive skills due to being passive learners, having too much external regulation, and other executive functioning issues that stem from hearing loss. The literature reveals self-directed learning is important in adult learning including on-the-job training and developing good managerial skills. The implications from the literature suggests that by increasing metacognitive skills in a formal setting, through means of active learning and scaffolding, Deaf and hard of hearing students can increase the use of metacognition in their learning which could have lifelong applications for academic success. This study will address the Deaf and hard of hearing students' deficits in metacognition through an educational intervention of dialogic teaching and evaluate the promotion of self-regulated learning.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-08-01The student, Bryan DeLauney, accepted the attached license on 2021-07-13 at 13:48.The student, Bryan DeLauney, submitted this Dissertation for approval on 2021-07-13 at 14:23.This Dissertation was approved for publication on 2021-07-16 at 10:25.DSpace SAF Submission Ingestion Package generated from Vireo submission #16779 on 2022-01-12 at 13:04:00Made available in DSpace on 2022-01-12T22:54:57Z (GMT).

The partitioning and distribution of zinc, nickel, chromium and copper in western Lake Erie sediments.
No full textPrevious research on trace metals in aquatic sediments have employed nonselective extractants which do not address the partitioning of trace metals. Partitioning data is important in environmental geochemistry because it can reveal a great deal of information about the source and distribution of the trace metals. A sequential extraction procedure was designed to examine the partitioning of anthropogenically derived Zn, Ni, Cr, and Cu in western Lake Erie sediment. The <63 micron size fraction of twenty surficial sediment samples were subjected to a three step extraction procedure that examined trace metals: (1) adsorbed on the surface of sediment grains and/or bound to carbonates, using 1.0M Na-Acetate; (2) bound to organic matter, using 0.1M Na-pyrophosphate; and (3) bound to Fe-Mn oxides, using 1.0 M Hydroxylamine hydrochloride.

How well must surface vorticity be organized for tornadogenesis?
No full textThis study investigates whether quasi-random surface vertical vorticity is sufficient for tornadogenesis when combined with an updraft typical of tornadic supercells. The viability of this pathway could mean that a coherent process to produce well-organized surface vertical vorticity is rather unimportant. Highly idealized simulations are used to establish random noise as a possible seed for the production of tornado-like vortices (TLVs). A number of sensitivities are then examined across the simulations. The most explanatory predictor of whether a TLV will form (and how strong it will become) is the maximal value of initial surface circulation found near the updraft. Perhaps surprisingly, sufficient circulation for tornadogenesis is often present even when the surface vertical vorticity field lacks any obvious organized structure. The other key ingredient for TLV formation is confirmed to be a large vertical gradient in vertical velocity close to the ground (to promote stretching). Overall, it appears that random surface vertical vorticity is indeed sufficient for TLV formation given adequate stretching. However, it is shown that longer-wavelength noise is more likely to be associated with substantial surface circulation (because it is the areal integral of vertical vorticity). Thus, coherent vorticity sources that produce longer wavelength structures are likely to be the most supportive of tornadogenesis.The CM1 model requires a fortran compiler (see https://www2.mmm.ucar.edu/people/bryan/cm1/ for more information).

The emergence of sustainability culture and the sustainability practitioner
No full textIn this thesis, I propose that sustainability is a new emergent cultural phenomenon – a new “dreaming” - arising from our conscious and unconscious actions, our relationships and our connection to place. Such a culture of sustainability is essential to support the vision of a sustainable global society. I further propose that the way sustainability is practised, both personally and professionally, has significant potential for fostering the emergence of sustainability culture, and that a mature sustainability culture, in turn, will support our myriad actions towards sustainability. The above propositions have a significant caveat: emergence, as understood in complexity theory, is not predictable. The current unsustainable paradigm of global development is also an emergent phenomenon. Real sustainability is therefore not inevitable, simply because a vision has been articulated, and strategies and actions implemented.
I also contend that as sustainability is holistic in conception, it requires a holistic approach to practice, in addition to the mechanistic prescriptions common to much contemporary sustainability practice. To move towards a holistic approach to practice requires a different type of practitioner from the conventional practitioner: more generalist than specialist, drawing on their “inner sustainability culture” when faced with complex sustainability problems, capable of working across scales, open to discovery of new patterns, and mindful of the degree of complexity in any practice setting.
In recognition of the need for a new cultural paradigm of sustainability, and drawing on the concept of emergence as described by complexity theory, I have designed this research project to investigate the following four themes:
1. Culture as an emergent quality of complex adaptive socio-technical systems;
2. The connections between human action and emergent system qualities;
3. The prospects for the emergence of a culture of sustainability; and
4. The implications of emergent sustainability culture for the sustainability practitioner.
In this thesis, I argue that we need a model of sustainability culture that accommodates the emergence phenomenon and new ways of emergence-based sustainability practice. I therefore propose an Emergence Model of Sustainability Culture to illustrate the relationship between sustainability, culture and the emergence phenomenon, and I articulate four Emergence Patterns for Sustainability Practice as a working framework for emergence-oriented sustainability practice across different generic practice settings in simple, complicated, complex and chaotic space. I hope that sustainability practitioners will find my Emergence Model and Emergence Patterns to be helpful in progressing to a more considered and deeper approach to sustainability practice than contemporary approaches, especially where sustainability problems are complex and difficult. In this way we may continue to develop a culture of sustainability as a new “dreaming” and the practice of sustainability will progress further to service humanity’s compelling need

Adapted metrics and random walks on graphs
No full textThis thesis discusses various aspects of continuous-time simple random walks on measure weighted graphs, with a focus on behaviors related to large-scale geometric properties of the underlying graph. In contrast to previous work in this area, the majority of the results presented here are applicable to random walks with unbounded generators. A recurring theme in this research is the use of novel distance functions for graphs known as adapted metrics, which are demonstrated to be a powerful tool for studying random walks on graphs.
Chapter 2 provides an overview of the relevant probabilistic and analytic theory, and provides multiple constructions of the heat kernel and a brief introduction to the theory of Dirichlet forms. Chapter 3 introduces adapted metrics, which play a central role in the following chapters, and which are especially useful in understanding random walks with unbounded generators. Chapter 4 discusses heat kernel estimates, and presents an overview of on-diagonal heat kernel estimates for graphs, as well as techniques for obtaining various off-diagonal estimates of the heat kernel. The off-diagonal estimates were proved by the author, and are notable for their use of adapted metrics. Chapter 5 introduces metric graphs, a continuous analogue of graphs which possess many desirable analytic properties, and analyzes the problem of constructing a Brownian motion on a metric graph which behaves similarly to a given continuous-time simple random walk. Chapter 6 analyzes recurrence and transience of graphs, and proves an original estimate relating adapted volume growth to recurrence of graphs. Chapter 7 discusses bounds for the bottom of the essential spectrum in terms of geometric inequalities such as volume growth estimates and isoperimetric inequalities. The main result of this chapter was proved by the author, and establishes sharp estimates for the bottom of the spectrum in terms of the adapted volume growth. Chapter 8 considers stochastic completeness of graphs and proves sharp criteria relating volume growth to stochastic completeness. The results of this chapter were proved by the author, using the machinery of metric graphs.Science, Faculty ofMathematics, Department ofGraduat
The sense of a beginning : Bakhtinian dialogic criticism on 'the gospel' in Mark.
No full textContemporary literary approaches have caused paradigm shifts in Biblical Studies in the last two decades as it appears in a great deal of Markan studies using narrative, reader-response, deconstructive, feminist, and new historicist approaches. However, literary studies on the Gospel of Mark have not taken into account theoretical questions underlying those approaches. As a result biblical critics are driven by new trends without ever having a chance to examine the critical baggage of the approaches. Consequently, there is a gap of communication between the old and the new one. Therefore this thesis is an attempt to meet the need of enhancing the quality of critical endeavour in biblical studies. In the light of most recent competing critical theories of literature, the first contribution of this thesis is the methodological finding that Bakhtinian dialogic criticism contains the most profound philosophical and practical foundations for solving some crucial theoretical problems in contemporary literary theories. It is a critique to a Saussurian linguistic system of language which becomes the very foundation of modern and postmodern literary criticism. Bakhtinian literary theory shifts the foundation of literary criticism on linguistic signs into the creative activity of the socio-cultural production of human communication. The shift into socio-cultural reality of language communication makes the notion of 'genre' very important to unlock the problem of text and context in literary studies. Since the Gospel of Mark has fascinated most literary critics in Biblical Studies, the problem of 'genre' of this gospel is chosen as the focus of this study. Secondly, as no agreement is reached as to what 'genre' the Gospel of Mark belongs, this thesis makes its contribution to the discussion by locating the problem of 'genre' of Mark in the context of genre theories and argues that the Bakhtinian suggestion to find genre in the socio-cultural sphere by analysing artistic intercourse between narrative agents in Mark has freed the competing analysis from the unresolved problem between the kerygmatic (content oriented) approach and the analogical (form oriented) approach. To achieve finding 'genre' in the socio-cultural sphere, this thesis focuses on Bakhtinian analysis of the process of artistic intercourse between narrative agents. The narrative communicative interrelationships between narrative agents is constructed in this thesis as a 'stereophonic' Bakhtinian model of dialogic communication. This model is an original contribution of this thesis for revising the traditional two dimensional model of narrative communication. Based on this dialogical model of communication, a special role is given to the Bakhtinian 'author-creator' in the realization process of genre through the interaction of polyphonic voices. Through the interaction of voices of the author-artist and the hero we are led to discover a relatively stable type of portraying and controlling reality in Mark, known as the genre of Roman 'satire'. The closest literary affinity is Satyrica by Petronius. This narrative strategy of 'satire' in Mark has its root in the prophetic discourse of the Old Testament which is saturating the speech of the narrator, John the Immerser, the centurion, the people, and even Jesus. Finally, the whole search for Markan 'genre' culminates in the analysis of the realization of genre through the analysis of Bakhtinian chronotope. The reality of the genre of Mark is its social reality that is in its role as dpxrj/ 'beginning'. As the Gospel of Mark proclaims itself as 'a beginning', it defines its claim of socio-cultural 'authority' in early Christianity. It is this 'sense of beginning' which enables the narrating and the narrated world of Mark to interact dialogically
The Role of WhatsApp in Developing L2 Spanish Learners' Intercultural Sensitivity: An Exploratory Task-Based Language Study in a Language Immersion Setting
No full textabstract: Technology (i.e. the WhatsApp mobile application) can play a positive role in a student’s language and culture learning when it is used in collaboration with a language curriculum that uses a modular framework. When technology tools are used in an intensive language learning environment, those mobile devices will allow students certain affordances (like modifying, authoring, and reviewing content) as well as opportunities to work independently (e.g., create their own content to demonstrate cultural understanding) and/or to reflect upon cross-cultural issues that impact their intercultural sensitivity (Lee, 2011). Barker (2016) adds that cultural discussions performed during a student’s language learning process can lead to intercultural sensitivity development and learning if done communicatively and in engaging environments. In this study, participants intensely interacted in a three week immersion experience where they used WhatsApp to communicate with each other, with their instructors, and with their host families by completing tasks in three modules that were a part of an Advanced Spanish Conversation and Culture Course.
The argument in this study is that if WhatsApp is well integrated into the course activities and curriculum of an upper level Spanish university course while abroad, the students will use more innovative ways to communicate, thus, allowing for more intercultural sensitivity growth. In this study, the author analyzed the intercultural sensitivity development and Spanish language use of twelve university level students as they learned Spanish in a 13 week study abroad program abroad in Segovia, Spain. The goal of the study was to gauge how effectively the students communicated with one another while simultaneously measuring their intercultural sensitivity growth to see if the integration of the mobile app, WhatsApp, had any effect on their intercultural learning capabilities. The author analyzed data from twelve learners’ interactions while they studied abroad in a country that they were mostly unfamiliar with. As a result of WhatsApp’s various modalities and capabilities, the findings showed that all of the 12 students showed modest intercultural sensitivity growth along the Developmental Model of Intercultural Sensitivity Scale (Bennett, 1993) to assist them in more effectively communicating in the target language about the host culture.Dissertation/ThesisDoctoral Dissertation Spanish 202
