Graphical Data Mining for Computational Estimation in Materials Science Applications

In domains such as Materials Science experimental results are often plotted as two-dimensional graphs of a dependent versus an independent variable to aid visual analysis. Performing laboratory experiments with specified input conditions and plotting such graphs consumes significant time and resources motivating the need for computational estimation. The goals are to estimate the graph obtained in an experiment given its input conditions, and to estimate the conditions needed to obtain a desired graph. State-ofthe-art estimation approaches are not found suitable for targeted applications. In this dissertation, an estimation approach called AutoDomainMine is proposed. In AutoDomainMine, graphs from existing experiments are clustered and decision tree classification is used to learn the conditions characterizing these clusters in order to build a representative pair of input conditions and graph per cluster. This forms knowledge discovered from existing experiments. Given the conditions of a new experiment, the relevant decision tree path is traced to estimate its cluster. The representative graph of that cluster is the estimated graph. Alternatively, given a desired
W. E. B. Du Bois and the Atlanta University Studies on the Negro

In 1897, W. E. B. Du Bois was called to Atlanta University by President Horace Bumstead. The young Harvard Ph.D. was employed to supervise the sociology program and to direct a series of conferences on Negroes which Atlanta had newly sponsored. The institution was an unusual Negro school because it operated contrary to many of the Southern conventions. Negro students and white faculty shared the same dormitories and dining hall, and white students who sought admission were not turned away. At least partly because of these social deviations, Atlanta received no money from the Georgia Legislature, and not a few Southerners thought of burying the school by means of oppressive taxation. Over the years, local newspapers published a spate of diatribes, and the institution was accused of teaching racial egalitarianism. ' Northerners on the faculty were looked upon as meddlers seeking to incite Negroes against whites. The General Education Board, which "stood before [Atlanta] almost as an evil monster," was unsympathetic with the manner in which the school was governed, since the foundation advocated a rapprochement with the white South and its mores.2
A prospective examination of post‐traumatic stress disorder in rape victims

Post-traumatic stress disorder (PTSD) and related psychopathology were examined in 95 female rape victims beginning soon after the assault (mean=12.64 days). Subjects were assessed weekly for 12 weeks. Ninety-four percent of women met symptomatic criteria for PTSD at Assessment 1, decreasing to 65% at Assessment 4 (mean=35 days postassault), and 47% at Assessment 12 (mean=94 days postassault). PTSD and related psychopathology decreased sharply between Assessments 1 and 4 for all women. Women whose PTSD persisted throughout the 3-month study did not show improvement after the fourth assessment; women who did not meet criteria for PTSD 3 months postassault showed steady improvement over time. This pattern was evidenced even after initial PTSD severity was statistically controlled. Moreover, PTSD status at 3 months postassault could be predicted with a high degree of accuracy by two brief self-report measures administered at the first assessment. The implications of the present findings and directions for future research are discussed.
Arbuscular Mycorrhizal Fungi (AMF) as Buffer for Heavy Metals Phytoextraction by Cucurbita maxima Duch. Grown on Crude Oil Contaminated Soil

This study evaluated the influence of Arbuscular Mycorrhizal (Rhizophagus irregularis) fungi inoculation (M) on the growth ofCucurbita maximaand as a buffer against phytoextraction of selected heavy metals (HM) (Zn, Cu, Cr, Cd and Pb) from a soil contaminated with crude oil (C). The experiment was set up using four soil treatments, each with three replicates C+ M-, C+ M+, C-M+ and C-M- (control without oil and inoculum). The shoot length, petiole length, number of nodes, leaf area and percentage germination ofC. maximawere significantly (p=0.05) reduced in uninoculated crude oil treatment (C+ M-), unpolluted mycorrhizal inoculated treatments (C-M+) showed remarkable response in growth parameters above the control (C-M-), while the polluted and inoculated treatment (C+ M+) showed significant (p=0.05) increase in growth parameters when compared to the polluted uninoculated treatment (C+ M-). Heavy metals analysis revealed a significant (p=0.05) difference in the heavy metal accumulation ofC. maxima. The heavy metals analyzed in this study are present thus inC. maxima; Zn>Cu>Cr>Pb>Cd. Crude oil polluted uninoculated treatment (C+ M-) recorded the highest concentrations of heavy metals than crude oil polluted inoculated (R. irregularis) treatment (C+ M+). Mycorrhizal inoculated unpolluted treatment (C-M+) and unpolluted uninoculated treatment (C-M-) indicated the lowest heavy metal concentrations. Inoculation withR. irregularissignificantly (p=0.05) reduced heavy metals uptake byC. maximaas observed in this study. Also, the negative effect of crude oil on AMF root colonization ofC. maximabyR. irregulariswas observed in polluted and inoculated treatment. HM often accumulate in the top layer of soil, therefore, are available for uptake by plants via roots, which is a major entry point of HM that ultimately affects different physiological processes. AM fungi can impinge on the chemical properties of heavy metals in the soil, their absorption by the host plant, and their allocation to different plant parts, affecting plant growth and the bioremediation process, thus making the AM fungi a suitable buffer for mitigating heavy metal stress onC. maxima.
The Facts and the Values of the Lucas Critique

ABSTRACT In his influential 1976 paper, ‘Econometric Policy Evaluation: A Critique,’ Robert E. Lucas, Jr. presented the policy non-invariance argument, also known as the Lucas critique (LC). Drawing on the work of Putnam and Walsh, this paper discusses how the LC, like all works of scientific inquiry, contains values entangled with scientific facts, and argues that the Lucas critique devalued and revalued the highest values in macroeconomic science, a process known as ‘transvaluation. ’ Most importantly, the LC worked to operationalize a shift in values that undermined belief in economists’ ability and responsibility to make meaningful interventions in the economy. Employing the language and concepts of continental philosophy, this paper discusses the meaning and effect of the LC on the values embedded in contemporary macroeconomic science.
Digital Transformation of Business Models

Abstract The goal of the article is to present the scope of changes in the morphology of business models in contemporary organizations that took place in the recent decades, because of the massive technological development, framed under the concept of “digital transformation (DT). ” An enhanced business model canvas concept is used as a base for presenting the changes, with a general time cutoff set in the year 2000. For the period before and after this measurement date, key elements of the business model and the drivers of their transformation are documented in a structured form and commented, together with practical conclusions and proposed further study areas
Goodwill Accounting and Asymmetric Timeliness of Earnings

Purpose - The purpose of this paper is to investigate how fair value reporting and increased managerial discretion under the new goodwill accounting affect the asymmetric timeliness of earnings;, i.e. accounting conservatism. Design/methodology/approach - Various empirical models are applied to a sample of 11,034 firms. To capture a cross-sectional variation in asymmetric timeliness of earnings, Kahn and Watts' C_Score is adopted. Findings - It is found that financial reporting for firms with purchased goodwill has become more conservative after the enactment of the new standard. However, once an increase in conservatism that is not attributable to new goodwill accounting is controlled for, it is found that accounting earnings for firms with purchased goodwill become less conservative. Research limitations/implications - The results should be interpreted with caution, because the effect of concurrent events other than the adoption of SFAS 142 on reported earnings is not perfectly controlled. Practical implications - The results of this paper support Watts' assertion that new goodwill accounting impairs accounting earnings' ability to reflect the economic earnings in a timely manner, but these results should be interpreted with caution, as the main objective of goodwill accounting is not to improve accounting conservatism. Originality/value - This paper makes a timely contribution to the debate of fair value accounting by focusing on the impact of SFAS 142 on the asymmetric timeliness of earnings. By employing all available firms with purchased goodwill balances rather than relying on firms that report impairment losses, our research design better captures the impact of SFAS 142 on financial reporting.

A population based on twin study examining the relationship between subjective well-being and major depression

Are happiness and depression related or completely distinct constructs? Using data from the Norwegian Institute of Public Health Twin Panel, we investigated the common and specific genetic and environmental contributions to subjective well-being (SWB) and liability to lifetime major depression. The results show that a substantial portion of both genetic and nonshared environmental variance is shared between major depressive disorder and SWB. These findings indicate that intervention and treatment aiming to increase SWB may decrease the risk of major depression. Results also indicate that morbidity and vitality may not be entirely distinct constructs at least from a genetic point of view.
Medical students on the hospital ward: what do patients really think?

Interaction between students and patients is a universal and essential component of a high-quality medical education. However, little work has been done to assess the attitudes of inpatients towards medical students on the ward. This study thus aimed to elicit patients’ thoughts on the role and impact of medical students in the inpatient setting. A four-page questionnaire in English was developed and pre-tested for clarity among five inpatients in a large teaching hospital in London. …
Physicomechanical properties of irradiated SBR latex polymer‐modified cement mortar composites

This study investigated the effect of styrene–butadiene‐rubber (SBR) latex/cement ratio as well as γ‐irradiation dose on physicomechanical properties of cement mortar. Specimens were prepared with a different SBR/cement mass ratio of 2.5, 5, 10, 15, and 20. Two curing methods were used: wet cure and dry cure. The best specimens were irradiated to doses of 10, 30, and 50 kGy. The compressive strength, total porosity, and bulk density were studied. The result indicated that the compressive strength, total porosity, and the bulk densities of the composites decrease with increase in the polymer cement ratios. In addition, it was observed that the compressive strength of irradiated polymer‐modified cement mortar composites was improved with the increase in the γ‐irradiation dose, and the compressive strength of mix‐cured samples was higher than those wet‐cured samples at any irradiation dose. X‐ray diffraction, thermogravimetric analysis, acid attack, and microstructure of SBR‐modified cement mortar were characterized. J. VINYL ADDIT.

Towards a Disruptive Digital Platform Model

This study presents a framework to understand and explain the design and configuration of digital payment platforms and how these platforms create conditions for market entries. By embracing the theoretical lens of platform envelopment, we employed a multiple and comparative-case study in a European setting by using our framework as an analytical lens to assess market-entry conditions. We found that digital payment platforms have acquired market entry capabilities, which is achieved through strategic platform design (i.e., platform development and service distribution) and technology design (i.e., issuing evolutionary and revolutionary payment instruments). The studied cases reveal that digital platforms leverage on payment services as a mean to bridge and converge core and adjacent platform markets. In so doing, platform envelopment strengthens firms’ market position in their respective core markets. This study contributes to the extant literature on digital platforms, market entries, and payment.

Seasonal and Inter-Annual Variations in pCO2sea and Air-Sea CO2 Fluxes in Mid-Latitudes of the Western and Eastern North Pacific during 1999-2006: Recent Results Utilizing Voluntary Observation Ships

We have investigated the seasonal and inter-annual variations of the difference in partial pressure of CO2 between surface seawater (pCO2sea) and overlying air (pCO2air) and the air-sea CO2 flux in the mid-latitudes of the western North Pacific (WNP; 25-40°N, 140-170°E) and eastern North Pacific (ENP; 25-40°N, 120-150°W) from 1999 to 2006 using the latest voluntary observation ship data. In the WNP and ENP, the area-averaged ΔpCO2 (pCO2air-pCO2sea) was at its minimum in late summer (-4.6 to 6.7 µatm in the WNP and -32.5 to -20.5 µatm in the ENP) and at its maximum in late winter (51.0 to 59.8 µatm in the WNP and 35.1 to 46.2 µatm in the ENP). The WNP acts as a moderate sink for atmospheric CO2 (4.1 to 5.5 mmol m-2d-1), while the ENP acts as a weak sink (1.1 to 1.9 mmol m-2d-1). Because ΔpCO2 is mainly controlled by pCO2sea, we have evaluated the effect of the factors controlling pCO2sea: sea surface temperature (SST), salinity (SSS), dissolved inorganic carbon (TCO2), and total alkalinity (AT). In the WNP, not only SST but also TCO2 plays an important role in the seasonal pCO2sea variation, while the SST could only explain most of the pCO2sea variation in the ENP. From 1999 to 2006, pCO2sea increased at a significantly lower rate (0.53 ± 0.11 µatm yr-1) than pCO2air (1.81 ± 0.01 µatm yr-1) in the WNP, and at a slightly lower rate in the ENP (1.32 ± 0.16 µatm yr-1). The air-sea CO2 flux increased at a rate of 0.19 ± 0.05 mmol m-2d-1 yr-1 in the WNP and 0.09 ± 0.03 mmol m-2d-1 yr-1 in the ENP, suggesting that the WNP is a stronger sink for atmospheric CO2.
Vocabulary Learning Strategies Used by High Vocabulary Knowledge Students Studying in the 3rd Year English for International Communication Students

The purpose of this study was to investigate the vocabulary learning strategies used by high vocabulary knowledge students in the Faculty of Liberal Arts at Rajamangala University of Technology Srivijaya, Songkhla. The subjects of this research were 72 third-year students studying in English for International Communication Program in the academic year 2013. The subjects were then divided into two groups; the students with high and low vocabulary knowledge groups based on their vocabulary size scores and were asked to rate the vocabulary learning strategies questionnaire. The findings revealed that the students with high vocabulary knowledge used vocabulary learning strategies at the moderate level. The strategies that were rated at the highest level were using English-Thai dictionary, using English media, taking notes of the newly-learned words in class, learning the words by translating the word meaning, and asking classmates for meaning.
Has IFRS Enhanced Accounting Uniformity?

ABSTRACT I examine the effect of International Financial Reporting Standards (IFRS) adoption on the accounting uniformity of financial statements for a sample of large firms listed on Euronext. Using Taplin’s (A unified approach to the measurement of international accounting harmony*. Accounting and Business Research, 34(1), 57–73) uniformity index, I find that IFRS enhances uniformity of financial statements of firms within the same country (national uniformity) and between countries (international uniformity). The change in uniformity is not, however, homogeneous within and across jurisdictions that are subject to different accounting regulations before IFRS adoption. Those countries whose local GAAP was further from IFRS prior to adoption experience a greater increase in uniformity after IFRS adoption. I also find that international uniformity is increased most for items where IFRS eliminated divergence with local GAAP and for items where no regulation existed under local GAAP; when IFRS preserved the accounting choice set prescribed under local GAAP, uniformity does not increase. The main contribution relies on showing that the various forms of the relationship local GAAP-IFRS prior to the shift matter when examining the direct effect of IFRS adoption on the convergence of financial reporting practices.
CEO political ideology and credit risk assessment

In this study, I examine the role of CEO political ideology in the credit rating process. Credit rating agencies release their research methodologies for determining corporate credit ratings and identify managerial conservatism as one important factor that affects their risk assessments. The extant literature, however, has not investigated the relation between credit ratings and managerial conservatism, which, according to behavioral consistency theory, can be proxied by CEO political ideology. I hypothesize and find that firms run by Republicanleaning CEOs, who tend to have conservative political ideologies, enjoy more favorable credit ratings than firms run by Democratic-leaning CEOs. This finding holds after controlling for potential endogeneity and self-selection concerns, and is robust to a battery of sensitivity checks. In addition, I find that the association between CEO political ideology and credit ratings is more pronounced for firms with high uncertainty of information environment and for firms with weak corporate governance. I further mitigate the concern that economic bonding between CEOs and credit rating agencies may drive the results. Finally, I identify future earnings volatility and future return volatility as two possible channels through which CEO political ideology affects credit ratings, and show that CEO political ideology has a residual effect on credit ratings after controlling for these two channel variables.
