Europeanization and the Rise of Extremist Parties

Description: The research question addressed by this study is: what is the relationship between Europeanization and the rise of extremist parties? In particular I examine the impact of Europeanization on the rise of extreme right parties in Europe from 1984 to 2006. Europeanization in this paper is defined as a process whereby the transformation of governance at the European level and European integration as a whole has caused distinctive changes in domestic politics. This process of Europeanization is one part of a structure of opportunities for extremist parties (which also include social, economic, and electoral factors). Although this study finds that Europeanization does not have a statistically significant effect it is still an important factor when examining domestic political phenomenon in Europe.

High Efficiency High Power Blue Laser by Resonant Doubling in PPKTP

Description: I developed a high power blue laser for use in scientific and technical applications (eg. precision spectroscopy, semiconductor inspection, flow cytometry, etc). It is linearly polarized, single longitudinal and single transverse mode, and a convenient fiber coupled continuous wave (cw) laser source. My technique employs external cavity frequency doubling and provides better power and beam quality than commercially available blue diode lasers. I use a fiber Bragg grating (FBG) stabilized infrared (IR) semiconductor laser source with a polarization maintaining (PM) fiber coupled output. Using a custom made optical and mechanical design this output is coupled with a mode matching efficiency of 96% into the doubling cavity. With this carefully designed and optimized cavity, measurements were carried out at various fundamental input powers. A net efficie ncy of 81 % with an output power of 680 mW at 486 nm was obtained using 840 mW of IR input. Also I report an 87.5 % net efficiency in coupling of blue light from servo locked cavity into a single mode PM fiber. Thus I have demonstrated a total fiber to fiber efficiency of 71% can be achieved in our approach using periodically poled potassium titanyl phosphate (PPKTP). To obtain these results, all losses in the system were carefully studied and minimized.

Podcasting in an Eighth-Grade American History Class

Description: The purpose of this study was to see how students used podcasts in an eighth-grade American history unit and the value they placed on them as an educational tool. The 6-week study was conducted in a suburban middle school in a district that is part of a large metropolitan area in Texas. Participants included 29 students and 2 eighth-grade teachers. The research questions were the following: (1) How do students use podcasts in an eighth-grade American history class? (2) How do students perceive the impact of the podcasts on their overall learning of the subject material? and (3) Do the podcasts motivate the students to study? Quantitative data were collected through a Likert-scaled student survey and logs kept by students. Qualitative data were collected through an open-ended portion of the student survey, student focus group discussion, and a faculty interview. The treatment tools were audio podcasts in the form of vocabulary-quiz reviews, historical vignettes, lectures, and a unit test review—all on the topic of the American Revolution. The data indicated that the students primarily used their computers at home to listen to the podcasts as they prepared for quizzes and/or the unit test. The students believed that the podcasts had a positive impact upon their grade, were a positive educational tool, and helped them to better understand the material at hand. The students also wanted to see an expansion of podcast usage in other subjects. The students claimed that it motivated them to study and the participating teachers agreed that it motivated the students to study in a non-traditional manner. Data illustrated a need for further research regarding podcasting’s impact on grades and performance at the K-12 level, student podcast construction, podcast delivery modes, and podcast use with special education and ELL students.

Integrating Selective Herbicide and Native Plant Restoration to Control Alternanthera philoxeroides (Alligator Weed)

Description: Exotic invasive aquatic weeds such as alligator weed (Alternanthera philoxeroides) threaten native ecosystems by interfering with native plant communities, disrupting hydrology, and diminishing water quality. Development of new tools to combat invaders is important for the well being of these sensitive areas. Integrated pest management offers managers an approach that combines multiple control methods for better control than any one method used exclusively. In a greenhouse and field study, we tested the effects of selective herbicide application frequency, native competitor plant introduction, and their integration on alligator weed. In the greenhouse study, alligator weed shoot, root, and total biomass were reduced with one herbicide application, and further reduced with two. Alligator weed cumulative stem length and shoot/root ratio was only reduced after two applications. In the greenhouse, introduction of competitors did not affect alligator weed biomass, but did affect shoot/root ratio. The interaction of competitor introduction and herbicide did not significantly influence alligator weed growth in the greenhouse study. In the field, alligator weed cover was reduced after one herbicide application, but not significantly more after a second. Introduction of competitor species had no effect on alligator weed cover, nor did the interaction of competitor species and herbicide application. This study demonstrates that triclopyr amine herbicide can reduce alligator weed biomass and cover, and that two applications are more effective than one. To integrate selective herbicides and native plant introduction successfully for alligator weed control, more research is needed on the influence competition can potentially have on alligator weed growth, and the timing of herbicide application and subsequent introduction of plants.

Dynamic Measurement of Intraoral Pressure and Sound Pressure With Laryngoscopic Characterization During Oboe Performance

Description: Measurements of intraoral pressure (IOP) and sound pressure level (SPL) were taken of four oboists as they performed two sets of musical exercises: (1) crescendo-decrescendo from pp to ff and back to pp on the pitches D4, G4, C5 and A5, and (2) straight and vibrato performances of the same four pitches at mf. Video images of the vocal tract were also made using flexible fiberoptic nasoendoscopy (FFN). IOP and SPL data were captured in real time by the WinDaq®/Lite software package, with the dB meter located 8-9 inches in directly front of the oboe bell. The study yielded minimum and maximum values from 21.04 to 57.81 mm Hg and from 65.53 to 100.89 dB across all pitches examined. Discussion is included for the following topics: (1) the oboe’s sound envelope, or functional range of IOP and SPL values at different pitch levels, including the nonlinearity in the relationship between IOP and SPL on the oboe, (2) the static activation and kinetic maintenance thresholds for reed vibration, (3) the effect of vibrato on IOP/SPL, (4) the utilization of the vocal tract during execution of dynamic changes and vibrato, and (5) the impact of player experience on control of physical variables.

The Threats to Compliance with International Human Rights Law

Description: In this project I investigate the factors shaping compliance with international human rights agreements and I provide a definition of compliance, which goes beyond “ratification.” I argue that compliance is a multistage process, built upon three different steps: ratification/accession, implementation, and what I call “compliant behavior.” As an alternative to the dominant structural and normative explanation of compliance, I suggest that the factors affecting compliance are not only endogenous to state characteristics, such as the democratic/non-democratic nature of governments, but also exogenous, such as the perceived level of threat to national security. I offer a twofold theory that looks at leaders’ behavior under conditions of stability and instability and I suggest that under certain circumstances that threaten and pressure government leaders, state compliance with international human rights law becomes more costly. I suggest that regardless of regime type, threats shape leaders’ behavior toward international law; states are faced with the choice to abide by international obligations, protecting specific human rights, and the choice to protect their national interests. I argue that when the costs associated with compliance increase, because leaders face threats to their power and government stability, threats become the predictor of non-compliant behavior regardless of the democratic or non-democratic nature of the regime.

Economic Motivation of the Ex-Dividend Day Anomaly: Evidence from an Alternative Tax Environment

Description: Several studies have observed that stocks tend to drop by an amount that is less than the dividend on the ex-dividend day, the so-called ex-dividend day anomaly. However, there still remains a lack of consensus for a single explanation of this anomaly. Different from other studies, this dissertation attempts to answer the primary research question: How can investors make trading profits from the ex-dividend day anomaly and how much can they earn? With this goal, I examine the economic motivations of equity investors through four main hypotheses identified in the anomaly’s literature: the tax differential hypothesis, the short-term trading hypothesis, the tick size hypothesis, and the leverage hypothesis. While the U.S. ex-dividend anomaly is well studied, I examine a long data window (1975 to 2010) of Thailand data. The unique structure of the Thai stock market allows me to assess all four main hypotheses proposed in the literature simultaneously. Although I extract the sample data from two data sources, I demonstrate that the combined data are consistently sampled. I further construct three trading strategies: “daily return,” “lag one daily return,” and “weekly return” to alleviate the potential effect of irregular data observation. I find that the ex-dividend day anomaly exists in Thailand, is governed by the tax differential and is driven by short-term trading activities. That is, investors trade heavily around the ex-dividend day to reap the benefits of the tax differential. I find mixed results for the predictions of the tick size hypothesis and results that are inconsistent with the predictions of the leverage hypothesis. I conclude that, on the Stock Exchange of Thailand, juristic and foreign investors can profitably buy stocks cum-dividend and sell them ex-dividend while local investors should engage in short sale transactions. On average, investors who employ the daily return strategy have earned significant abnormal ...

Comparing Latent Dirichlet Allocation and Latent Semantic Analysis as Classifiers

Description: In the Information Age, a proliferation of unstructured text electronic documents exists. Processing these documents by humans is a daunting task as humans have limited cognitive abilities for processing large volumes of documents that can often be extremely lengthy. To address this problem, text data computer algorithms are being developed. Latent Semantic Analysis (LSA) and Latent Dirichlet Allocation (LDA) are two text data computer algorithms that have received much attention individually in the text data literature for topic extraction studies but not for document classification nor for comparison studies. Since classification is considered an important human function and has been studied in the areas of cognitive science and information science, in this dissertation a research study was performed to compare LDA, LSA and humans as document classifiers. The research questions posed in this study are: R1: How accurate is LDA and LSA in classifying documents in a corpus of textual data over a known set of topics? R2: How accurate are humans in performing the same classification task? R3: How does LDA classification performance compare to LSA classification performance? To address these questions, a classification study involving human subjects was designed where humans were asked to generate and classify documents (customer comments) at two levels of abstraction for a quality assurance setting. Then two computer algorithms, LSA and LDA, were used to perform classification on these documents. The results indicate that humans outperformed all computer algorithms and had an accuracy rate of 94% at the higher level of abstraction and 76% at the lower level of abstraction. At the high level of abstraction, the accuracy rates were 84% for both LSA and LDA and at the lower level, the accuracy rate were 67% for LSA and 64% for LDA. The findings of this research have many strong implications for the ...

Senior Graduating Nursing Students: Career Choices in Gerontological Nursing in Response to Expanding Geriatric Population

Description: Access to healthcare is needed and wanted by people of all ages and especially by those of the older population. The number of people in the 65 years of age and older population is rapidly growing with their needs expected to have a significant impact on the existing healthcare system and healthcare providers. The impact will be critical given the severe shortage of healthcare providers, especially of nurses and the rate of services being more often provided in non-hospital settings. The objectives of the study were to discover the plans of graduating nursing students as they choose their first place of employment, if they have future plans to pursue a nursing advance practice degree, and if they are very happy with their decision to become a nurse. Data for the study were obtained from a questionnaire presented to senior graduating nursing students. The findings were: (a) Most students prefer a hospital setting. (b) Younger students are three times as likely to seek out the hospital, and 1/3 of the students seek out the hospital setting because they were encouraged to become a nurse. (c) About 70% of the students want to work with their friends while 1/3 will seek the hospital worksite, as it is perceived as being the strongest resource in paying back loans. (d) Nearly 87% are considering the nursing advance practice role, and 52% have interest in the nurse practitioner role. The majority of students identified as very happy with their decision to become a nurse. This study provided insight for schools of nursing as they make curriculum decisions and to businesses as they learn of the preferences and plans of the new emerging nurses.

Predictive Relationships among Learner Characteristics, Academic Involvement, and Doctoral Education Outcomes

Description: The literature identifies multiple factors pertinent to learner characteristics and learning experiences that may promote doctoral education outcomes, and yet little quantitative research has examined relationships between those factors deemed important in the effectiveness of doctoral education. This study sought to examine predictive relationships among doctoral students’ learner characteristics, their involvement in mentorship and intellectual community, and doctoral education outcomes. Using Astin’s theory of involvement and the literature on signature pedagogies in doctoral education as conceptual guides, a survey instrument was constructed for the purpose of measuring variables identified as relevant to the effective formation of scholars. Central to the conceptualization of this study was academic involvement as represented by mentorship and intellectual community. The instrument was validated in a two-stage pilot testing process and administered to doctoral candidates at three public Texas higher education institutions. Of the 217 participants, the majority were female, White (Non-Hispanic), US citizens, and were pursuing education doctorates. Data were analyzed using multivariate statistical analyses. Reliability and validity estimates indicated psychometric integrity of the 20 observed variables measured to represent the constructs of mentorship and intellectual community. Results indicated that doctoral students’ learner characteristics were not notably predictive of doctoral students’ degree of involvement in mentorship and intellectual community (p < .05, R2 = .23). Doctoral students’ degree of academic involvement was strongly predictive of outcomes (p < .001, R2 = .58), particularly student satisfaction with the doctoral education experience and self-efficacy in conducting various forms of scholarly work. Of this effect, more tangible outcomes such as scholarly productivity and degree progress were not meaningfully related to academic involvement. Regardless of the frequency of academic involvement, students perceived faculty mentorship and intellectual community as very important. The predictive value and perceived importance of faculty mentorship and intellectual community highlight the critical role faculty and peer ...

Interfacial Electrochemistry of Copper and Spectro-Electrochemical Characterization of Oxygen Reduction Reaction

Description: The first part of this dissertation highlights the contents of the electrochemical characterization of Cu and its electroplating on Ru-based substrates. The growth of Ru native oxide does diminish the efficiency of Cu plating on Ru surface. However, the electrochemical formed irreversible Ru hydrate dioxide (RuOxHy) shows better coverage of Cu UPD. The conductive Ru oxides are directly plateable liner materials as potential diffusion barriers for the IC fabrication. The part II of this dissertation demonstrates the development of a new rapid corrosion screening methodology for effective characterization Cu bimetallic corrosion in CMP and post-CMP environments. The corrosion inhibitors and antioxidants were studied in this dissertation. In part III, a new SEC methodology was developed to study the ORR catalysts. This novel SEC cell can offer cheap, rapid optical screening results, which helps the efficient development of a better ORR catalyst. Also, the SEC method is capable for identifying the poisoning of electrocatalysts. Our data show that the RuOxHy processes several outstanding properties of ORR such as high tolerance of sulfation, high kinetic current limitation and low percentage of hydrogen peroxide.

Electronic Sound Analysis with Hardware System and Remote Internet Display

Description: Currently, standards from government agencies such as the National Institute for Occupation Safety and Health exist to aid in safeguarding individuals’ capacity for hearing, but only in factory settings in which large machines often produce loud levels of sound. Neglecting the fact that these preventative measures are only in place in the most limited of settings, no system currently exists to observe and report sound exposure levels in a manner timely or easily recognizable enough to adequately serve its purpose of hearing conservation. Musicians may also incur significant levels of risk for hearing loss in their day-to-day rehearsals and concerts, from high school marching bands to university wind bands. As a result, music school accrediting organizations such as the National Association of Schools of Music and even the European Union have begun taking steps meant to determine the risks associated with music. To meet these goals and improve upon current technologies, a system has been developed that electronically records sound levels utilizing modern hardware, increases the speed of reporting by transmitting data over computer networks and the Internet, and displays measures calculated from these data in a web browser for a highly viewable, user-friendly interface.

The Relationship Between Professional Sexual Boundary Violation And Sex Addiction: An Exploratory Study Of Post-treatment And Retrospective Pre-treatment Dispositions

Description: In this exploratory study, 35 male professionals who had successfully completed residential sex addiction treatment were surveyed. Respondents’ median age was 47.5, and reported ethnicities were White (89%), Asian, (9%) and Hispanic (2%). Prior to intake, 17 respondents had reportedly violated sexual boundaries with patients, clients, or staff (BV group) and 18 reportedly had not (NBV group). Respondents completed a demographic information form and two validated instruments: (a) Sexual Symptom Assessment Scale (S-SAS), measuring symptom severity of Compulsive Sexual Behavior (CSB); and (b) Boundary Violation Index (BVI), assessing frequency of risk factors for Sexual Boundary Violation (SBV). Respondents reported a very large decrease in CSB symptom severity over time (partial 2 = .856), change that was statistically equal for respondents in the BV and NBV groups. Furthermore, respondents reported a large decrease in SBV risk over time (partial 2 = .620); however, the BV group reported a greater decrease in SBV risk than the NBV group (partial 2 = .221). Reductions in both CSB symptoms and SBV risk were stable over time, up to five years post discharge. CSB symptoms and SBV risk were not correlated at retrospective pre-treatment, but for practical purposes, were moderately correlated at post treatment (r = 0.386, n = 25, p = 0.057). Although not significant, correlation at pre-treatment was more than twice as strong for the BV group than for the NBV group. Days of Treatment was a meaningful, although non-significant, contributor to decreases in CSB symptom severity (? = -.323). Similarly, Days of Treatment (? = -.785), Counseling (? = -.303), Recovery Support (? = -.292), and Continuing Education (? = -.259) were meaningful, although non-significant, contributors to decrease in SBV risk. At study participation, 77.1% of respondents had reportedly retained their professional licenses, although 15.4% reported having received a new licensing board ...

Correlates Of Three Year Transfer Student Retention Rates With Race, Gender, Age, Credit Hours, And Place Of Residence At A Regional, Public University

Description: This dissertation examined the relationship between the three year academic success of transfer students and the variables of race, gender, age, number of transfer credit hours, and place of residence. The study was conducted at Midwestern State University, a public, regional four-year institution and followed the incoming transfer classes of the fall 2005 (N = 292), 2006 (N = 323), and 2007 (N = 286) semesters. The subjects included in this study were all new transfer students who met the university.s requirement to live on campus. The dependent variable, three year academic success, was defined as whether or not the student was still persisting or had graduated within three years from the date of initial enrollment. The independent variables were housing status during the first semester after transfer, age at time of transfer, gender, race, and the number of credit hours at the time of transfer. The first research question aimed to determine if housing status impacted the three year academic success in the population. Chi-square analysis found that there were no significant distributions of the students who lived on-campus and the students who lived off-campus during their first semester after transfer. The second research question aimed to determine if the variables of age at the time of transfer, credit hours at the time of transfer, gender, race, and campus housing status impacted three year success. Logistic Regression showed that only gender (.003) was significant at ? = .05. The Exp(B) value for gender (1.514), showed that females were 1.514 times more likely to be successful than males when all other variables were controlled. The effect size of .019 indicated that the model only accounted for 1.9% of the variance, indicating that the model may not be a great predictor of student academic success. The results of this study, conducted ...

Economic Mobility into the Planter Class in Texas, 1846-1860

Description: This study examines upward economic mobility into the planter class in Texas during the antebellum statehood period, 1846-1860. Using quantitative methods to analyze data from census and tax records, this study addresses several questions regarding the property owning experience of Texas planters. Did any of the 1860 planters, men or women, rise to that status from another class? If so, how many rose from small slaveholder or small planter origins, and how many advanced from plain folk origins? In what ways did the amount and nature of wealth of these individuals change in the period studied? In what ways do these findings provide insights into the debate over planter dominance versus ‘plain folk’ inclusive herrenvolk democracy and the relationship between the planters and the other classes? Did the experiences of female planters differ from that of male planters? Did female planter experiences in Texas differ from female planters in other parts of the Old South? The results of these questions demonstrate that economic class mobility into the richest class was significant but limited and that women’s experiences were closely tied to those of male kin.

Development of Silicon Nanowire Field Effect Transistors

Description: An economically reliable technique for the synthesis of silicon nanowire was developed using silicon chloride as source material. The 30-40 micron long nanowires were found to have diameters ranging from 40 – 100 nm. An amorphous oxide shell covered the nanowires, post-growth. Raman spectroscopy confirmed the composition of the shell to be silicon-dioxide. Photoluminescence measurements of the as-grown nanowires showed green emission, attributed to the presence of the oxide shell. Etching of the oxide shell was found to decrease the intensity of green emission. n-type doping of the silicon nanowires was achieved using antimony as the dopant. The maximum dopant concentration was achieved by post-growth diffusion. Intrinsic nanowire parameters were determined by implementation of the as-grown and antimony doped silicon nanowires in field effect transistor configuration.

Effectiveness Of Group Activity Play Therapy On Internalizing And Externalizing Behavior Problems Of Preadolescent Orphans In Uganda

Description: This pilot study investigated the impact of group activity play therapy (GAPT) on displaced orphans aged 10 to 12 years living in a large children.s village in Uganda. Teachers and housemothers identified 60 preadolescents exhibiting clinical levels of internalizing and externalizing behavior problems. The participants ethnicity was African and included an equal number of females and males. Participants were randomly assigned to GAPT (n = 30) or reading mentoring (RM; n = 30), which served as an active control. Preadolescents in both treatment groups participated in an average of 16 sessions, twice weekly with each session lasting 50 minutes. Sessions were held in the school located within the village complex. A two (group) by two (repeated measures) split plot ANOVA was used to analyze the data. According to teacher reports using the Teacher Report Form (TRF) and housemother reports using the Child Behavior Checklist (CBCL), children receiving the GAPT intervention demonstrated statistically significant decreases (p < .025) in internalizing behaviors (TRF: p < .001; CBCL: p < .001 ) and externalizing behaviors (TRF: p = .006; CBCL: p < .001) from pretest to posttest compared to children who received RM. The GAPT intervention demonstrated a large treatment effect on reducing orphaned childrenÆs internalizing problems (TRF: ?p2= .213; CBCL: ?p2 = . 244) and a moderate to large treatment effect on reducing externalizing problems (TRF: ?p2= .121; CBCL: ?p2 = .217). The statistical, practical, and clinical significance of the findings provided strong, preliminary support for using GAPT as a developmentally and culturally responsive school-based intervention for troubled Ugandan orphans.

Etude Comparative Et Intertextuelle Sur Le Thème Des “Fenêtres” Dans Quatre Poèmes De Charles Baudelaire, Stéphane Mallarmé, Marie Krysinska Et Guillaume Apollinaire.

Description: Written in French, this thesis presents a comparative and intertextual study on the theme of « windows » in four poems by Charles Baudelaire, Stéphane Mallarmé, Marie Krysinska and Guillaume Apollinaire. Charles Baudelaire (1821-1867), Stéphane Mallarmé (1842 -1898), Marie Krysinska (1857-1908) and Guillaume Apollinaire (1880-1918) use « windows » as a common theme in their poetry. My study compares this common theme found in four poems: (1) “Les fenêtres” by Charles Baudelaire in Spleen de Paris XXXV, 1869. (2) “Les fenêtres” by Stéphane Mallarmé in Le Parnasse Contemporain, 1863/66. (3) “Les fenêtres” by Marie Krysinska in Rythmes pittoresques, 1890. (4) “Les fenêtres” by Guillaume Apollinaire in Calligrammes (1913-1916), 1918. I focus on what distinguishes these fours poems by following the evolution of poetical forms between symbolism and futurism/surrealism. The common theme (“windows”) provides an opportunity to better underline the formal heterogeneity which separates these different “poetical avenues”: with Baudelaire, the newness of prose poetry; with Mallarmé, the symbolist renewal of a more classic form; with Apollinaire, a form of simultaneity inspired by futurism. The comparative analysis brings to light the original value of the poem written by Krysinska, whose works have not greatly captivated the attention of critics.

High School Teachers’ Perceptions Of Their Principals As Culturally Proficient Leaders

Description: This study examined Texas high school teachers’ perceptions of their principals as culturally proficient leaders, focusing specifically on how teacher-, school-, and principal-related factors impacted these perceptions. A sample of 104 teachers in culturally diverse secondary schools from a large urban district in Texas participated. An electronic survey was utilized to collect data. Results yielded an average total cultural proficiency score of 111 out of a possible 175, indicating that teachers perceived their principals “sometimes use” culturally proficient practices. Teachers’ perceptions of their principal’s use of culturally proficient leadership practices varied significantly by years of teachers’ experience and school accountability rating (exemplary, academically acceptable, and academically unacceptable). Perceptions of teachers at an Exemplary school were significantly different (higher than the perceptions of teachers at other schools from the same district). Teachers with 11 to 20 years of teaching experience gave significantly lower ratings (22.45 points) than teachers with 1 to 5 years of experience (125.53) and teachers with over 20 years of experience (118.94). While differences were not statistically significant, black and Hispanic teachers rated their principals’ culturally proficient practices higher than white teachers. Age, subject area taught and teacher’s gender, or race being the same as the principal’s gender or race had no significant effect on total proficiency scores. This study supports prior findings that leadership policy and development programs must be refined to help leaders develop and utilize more culturally proficient skills that will lead to greater academic success for all students. Results indicate that principals need assistance in adapting to and managing the dynamics of difference as well as providing teachers with conflict resolution training. It is recommended that professional development departments conduct similar district-wide proficiency assessments as a first step in helping educators to understand the cultural proficiency conceptual framework. It is also recommended that school ...

The Multi-reference Correlation Consistent Composite Approach: A New Vista In Quantitative Prediction Of Thermochemical And Spectroscopic Properties

Description: The multi-reference correlation consistent composite approach (MR-ccCA) was designed to reproduce the accuracy of more computationally intensive ab initio quantum mechanical methods like MR-ACPF-DK/aug-cc-pCV?Z-DK, albeit at a significantly reduced cost. In this dissertation, the development and applications of the MR-ccCA method and a variant of its single reference equivalent (the relativistic pseudopotential ccCA method) are reported. MR-ccCA is shown to predict the energetic properties of reactive intermediates, excited states species and transition states to within chemical accuracy (i.e. ±1.0 kcal mol 1) of reliable experimental values. The accuracy and versatility of MR-ccCA are also demonstrated in the prediction of the thermochemical and spectroscopic properties (such as atomization energies, enthalpies of formation and adiabatic transition energies of spin-forbidden excited states) of a series of silicon-containing compounds. The thermodynamic and kinetic feasibilities of the oxidative addition of an archetypal arylglycerol ?-aryl ether (?-O-4 linkage) substructure of lignin to Ni, Cu, Pd and Pt transition metal atoms using the efficient relativistic pseudopotential correlation consistent composite approach within an ONIOM framework (rp-ccCA-ONIOM), a multi-level multi-layer QM/QM method formulated to enhance the quantitative predictions of the chemical properties of heavy element-containing systems larger than hitherto attainable, are also reported.

Backflow: A Collection

Description: This collection consists of a critical preface and nine essays. The preface analyzes, first, how the imagination influences the personal journey of a writer, and second, the techniques authors use, mainly form, time, and space, to enact the imagination and propel the reader into an imagined narrative. The essays explore themes of loss, mental illness, the rift between the “real” and the “imagined” life, and the intangibility of memory itself. Collection includes the essays “Into the Snow,” “No Longer a Part,” “Borderland,” “Still Wounds,” “What Stays in Las Vegas,” “Remnants,” “The Root,” “Your Father,” and “The Land Lord.”
