Abstract:
Purpose – This paper aims to propose several factors which can explain the negative relationship between financial constraints and investment-cash flow sensitivity. Design/methodology/approach – The author uses traditional fixed effects model and minimum distance panel estimation by Erickson and Whited (2000) to estimate investment-cash flow sensitivity in the cash flow-augmented investment equation. In addition, principal component analysis is used to construct a financial constraints measure. Findings – First, it was found that substitutability between cash holdings and free cash flow can partially explain why financially constrained firms do not depend on cash flow as heavily as we expect. Second, it was confirmed that the level of net external financing can also partially explain the investment-cash flow sensitivity puzzle. Furthermore, it was argued that the influence of cash holdings and external financing on investment-cash flow sensitivity is caused by the low level of internal cash flow for financially constrained firms. This argument is supported by our findings from an examination of investment-cash flow sensitivity for bank-dependent firms during the recession periods. Originality/value – This paper contributes to the literature by suggesting possible partial explanations for the contradictory relationship between investment-cash flow sensitivity and financial constraints.

Abstract:
We use data from the New Immigrant Survey to examine patterns of residential attainment among Hispanic immigrants who recently became legal permanent residents (LPRs) relative to new LPR non–Hispanic white immigrants. We focus on whether these Hispanic and non–Hispanic white immigrants differ in their ability to transform human capital into residential advantage. Our results suggest that the answer depends on the neighborhood attribute in question. When predicting residence in tracts with relatively more non–Hispanic whites, the answer is yes, with evidence in support of the place stratification model of residential attainment. We find that non–Hispanic white immigrants have access to relatively whiter neighborhoods than their Hispanic immigrant counterparts, irrespective of differences in education levels. When assessing Hispanic immigrants’ ability to enter socioeconomically advantaged neighborhoods, however, the differences we observe are mostly accounted for by compositional differences in sociodemographic and acculturation factors. Taken together, our findings suggest that Hispanic immigrants are more similar to their white immigrant counterparts when it comes to converting higher education into higher income neighborhoods than into increased residential integration with whites; although their exposure to more socioeconomically advantaged neighborhoods at all levels of education remains lower than that of their white immigrant counterparts.

Abstract:
The purpose of the study is to determine whether there are ethnic differences in predictors of hearing protection behavior between Black and White workers. The Predictors of Use of Hearing Protection Model (PUHPM) derived from Pender’s Health Promotion Model (Pender, 1987) was used as a conceptual model. A total of 2,119 (297 Blacks, 1,822 Whites) were included in the analysis. Internal consistency of instrument items was assessed using theta reliability estimates. Significant predictors of the use of hearing protective devices (HPDs) for Black and White workers and differences in predictors between the two groups were examined using multiple regression with interaction terms. Ethnic differences in scale or individual item scores were assessed using chi-square and t-test analyses. Different factors influenced hearing protection behavior among Black and White workers. The model was much less predictive of Blacks’ hearing protection behavior than Whites’ (R2 = .12 vs. .36). Since the PUHPM was not as effective in predicting hearing protection behavior for Blacks as for Whites, future studies are needed to expand the PUHPM through qualitative study and to develop culturally appropriate models to identify factors that better predict hearing protection behavior as a basis for developing effective interventions.

Abstract:
The Center for Epidemiologic Studies Depression (CES-D) Scale has been widely used to measure depressive symptoms. This study compared the measurement invariances for one-, two-, three-, and four-factor models of the CES-D across English-speaking Whites and Asians: White Americans, White Australians, Indians, Filipinos, and Singaporeans. White Americans and Australians, Indians, Filipinos, and Singaporeans English speakers (782 men and 824 women) whose ages ranged from 20 to 79 years, completed the CES-D. They were recruited from the data pool of the 2013 and 2014 Coping and Health Survey. Confirmatory factor analyses indicated that the original four-factor model showed the best fit, compared to the other models. Mean and covariance structure analyses showed that the factor means of the CES-D subscales among Whites were significantly lower than were those among Asians; the score gap was particularly high between Whites and Indians. Additionally, Indians scored the highest on all subscales of the CES-D compared to all other countries. Overall, CES-D scores among Whites were lower than those among Asians.

Abstract:
The purpose of this study is to compare the reliability and predictability of transtheoretical model (TTM) constructs when applied to minority and White women at risk for HIV. Participants consisted of 332 women, including Blacks, Asians, Hispanics, Native Americans, other non-Whites, and Whites. The results supported the reliability and validity of the TTM variables for minority women as well as for White women. Hierarchical multiple regressions demonstrated that TTM variables were able to predict over and above demographic variables. Structural equation models indicate strong support for a mediational model in which the pros and cons predict condom stage of change and unprotected sex though the mediation of self-efficacy. This study provides strong support for TTM scales applied to minority as well as White women at risk for HIV. The authors discuss how these variables might be incorporated into interventions aimed at increasing condom use in minority women.

Abstract:
This article compares model characterizations and activity portrayals of blacks and whites in modern cigarette and alcohol advertising. An analysis of 418 cigarette and alcohol ads appearing in eleven magazines from June 1990 through June 1991 revealed a world in which blacks and whites smoke and drink separately, seldom encountering one another. Despite this segregation, black and white portrayals are similar in terms of sexual suggestiveness and involvement in erotic or romantic activities. However, noteworthy differences also exist. For example, blacks are more often portrayed in leisure activities while whites are portrayed at work. Femininity is a more dominant theme in black than in white representations, while masculinity themes are more dominant in ads with white representations.

Abstract:
This study examines the relationships between the employability and criminality of white and black male teenagers. A disequilibrium model of employment and crime is formulated and estimated as a simultaneous probit equation system. Our results show that black teenagers who are employed engage in fewer criminal activities. Thus, it appears that blacks view employment and crime as alternative income-generating activities. On the other hand, the criminal behavior of white male teenagers is unaffected by their employment status. The evidence that we provide indicates that whites tend to use employment as a cover for crime or to moonlight in crime. The differences in the behaviors of whites and blacks can be explained, in part, by different legitimate opportunity structures for whites and blacks. One of the more important policy implications is that job opportunities targeted to high risk, black teenage populations will have the additional beneficial effect of reducing crime rates.

Abstract:
Using a model of statistical discrimination and educational sorting, we explain why blacks get more education than whites of similar cognitive ability, and we explore how the Armed Forces Qualification Test (AFQT), wages, and education are related. The model suggests that one should control for both AFQT and education when comparing the earnings of blacks and whites, in which case a substantial black-white wage differential emerges. We reject the hypothesis that differences in school quality between blacks and whites explain the wage and education differentials. Our findings support the view that some of the black-white wage differential reflects the operation of the labor market. (JEL I21, J15, J24, J31, J71)

Abstract:
Актуальність теми. Актуальною задачею комп’ютерної графіки являється отримання реалістичних зображень, котрі активно користуються попитом в промисловості, ігровій індустрії та кіно.

Існує багатий спектр різноманітних методів трасування променів, отже з’являється необхідність у вибірці найбільш ефективних точних методів трасування променів, котрі будуть в середній мірі коректно працювати для широкого ряду статичних (в майбутньому і динамічних) сцен, що проходять візуалізацію. Об’єктом дослідження є процес фізично обґрунтованого рендерингу і процес трасування променів. Предметом дослідження є способи трасування променів та методи розрахунку індексу передачі кольору. Мета роботи: дослідження методів PBR (Physical Based Rendering), їх одночасного використання для отримання максимального ефекту реалізму; оцінка здатності джерела світла виявляти всі частоти його кольорового спектру у порівнянні з контрольним світлом.

Relevance of the topic. The actual task of computer graphics is to obtain realistic images that are actively in demand in industry, gaming and film industry. A photorealistic image is characterized by such effects as soft shadows, partial shade, caustic, dynamic blur, depth of field, fuzzy reflection, shine, translucency. Among the existing approaches of photorealistic visualization, ray tracing methods are the most accurate because they are based on a physical model of light propagation. There is a wide range of different ray-tracing methods, and therefore there is a need to select the most efficient, accurate ray-tracing methods that will, in average, work correctly for a wide range of static (future dynamic) scenes, and are being visualized. The object of the research is the process of physically sound rendering and the ray tracing process. The subject of research is the methods of ray tracing and methods for calculating the color rendering index. Objective: to study the methods of PBR (Physical Based Rendering), their simultaneous use to obtain the maximum effect of realism; assessment of the ability of a light source to detect all the frequencies of its color spectrum compared to the control light. The scientific novelty, or rather, an innovative solution, is that the engine developed implements the calculations of the color rendering index (CRI - Color Rendering Index) with a high degree of accuracy relative to the expected values of the control light sources. The practical value of the research is the development of a new PBRE, which employs empirical lighting models for rendering scenes; BRDF models such as Lambert, Oren Nayar, Torrens Sparrow, specular reflection, specular transmission and measured BRDF are implemented. Implemented support for several ray tracing techniques: Traced by Wyted and path tracing. Colors are calculated using spectral data and CIE XYZ color space in PBR scenes to achieve high color rendering. TTFD also supports Color Rendering Index (CRI) calculations. This indicator describes the ability of a light source to accurately reflect all the frequencies of its color spectrum compared to ideal reference light of a similar type. Structure and scope of work. Master thesis project consists of introduction, four chapters and conclusions. The introduction presents a general description of the work, assesses the current state of the problem, substantiates the relevance of the research area, formulates the goals and objectives of the research, shows the scientific novelty of the results and practical value of the work. The first section discusses the principles of colorimetry and radiometry. They form the basis of some key TTFD key features. In particular, color calculations and lighting / shading methods implemented in TTFD use the concept presented in this section. The second section deals with ray tracing: photorealistic rendering (visualization). Brief classification of ray tracing algorithms. Solution of the rendering equation. The third section presents the features of the implementation of the developed system. The fourth section presents approaches to testing the system as a whole and individual modules. The findings present the results of this work. The work is presented on 116 pages, contains links to the list of references used.
Актуальность темы. Актуальной задачей компьютерной графики является получение реалистичных изображений, которые активно пользуются спросом в промышленности, игровой индустрии и кино. Фотореалистичное изображение характеризуется такими эффектами, как мягкие тени, полутени, каустика, динамическое размытие, глубина резкости, нечеткие отражение, блеск, полупрозрачность. Среди существующих подходов фотореалистичной визуализации методы трассировки лучей являются наиболее точными, поскольку они базируются на физической модели распространения света.

Abstract:
The hybrid Heston-Hull-White (HHW) model combines the Heston (1993) stochastic volatility and Hull and White (1990) short rate models. Compared to stochastic volatility models, hybrid models improve upon the pricing and hedging of longdated options and equity-interest rate hybrid claims. When the Heston and HullWhite components are uncorrelated, an exact characteristic function for the HHW model can be derived. In contrast, when the components are correlated, the more useful case for the pricing of hybrid claims, an exact characteristic function cannot be obtained. Grzelak and Oosterlee (2011) developed two approximations for this correlated case, such that the characteristics functions are available. Within this dissertation, the approximations, referred to as the determinist and stochastic approximations, were implemented to price vanilla options. This involved extending the Carr and Madan (1999) method to a stochastic interest rate setting. The approximations were then assessed for accuracy and efficiency. In determining an appropriate benchmark for assessing the accuracy of the approximations, the full truncation Milstein and Quadratic Exponential (QE) schemes, which are popular Monte Carlo discretisation schemes for the Heston model, were extended to the HHW model. These schemes were then compared against the characteristic function for the uncorrelated case, and the QE scheme was found to be more accurate than the Milstein-based scheme. With the differences in performance becoming increasingly noticeable when the Feller (1951) condition was not satisfied and the maturity and volatility of the Hull-White model (⌘) was large. In assessing the accuracy of the approximations against the QE scheme, both approximations were similarly accurate when ⌘ was small. In contrast, when ⌘ was large, the stochastic approximation was more accurate than the deterministic approximation. However, the deterministic approximation was significantly faster than the stochastic approximation and the stochastic approximation displayed signs of potential instability. When ⌘ is small, the deterministic approximation is therefore recommended for use in applications such as calibration. With its shortcomings, the stochastic approximation could not be recommended. However, it did show promising signs of accuracy that warrants further investigation into its efficiency and stability.

Full text
Abstract:
Diffusion MRI microstructure imaging provides a unique noninvasive probe into tissue microstructure. The technique relies on mathematical models, relating microscopic tissue features to the MR signal. The assumption of Gaussian diffusion oversimplifies the behaviour of water in complex media. Multi-compartment models fit the signal better and enable the estimation of more specific indices, such as axon diameter and density. A previous model comparison framework used data from fixed rat brains to show that three compartment models, designed for intra/extra-axonal diffusion, best explain multi-b-value datasets. The purpose of this PhD work is to translate this analysis to in vivo human brain white matter. It updates the framework methodology by enriching the acquisition protocol, extending the model base and improving the model fitting. In the first part of this thesis, the original fixed rat study is taken in-vivo by using a live human subject on a clinical scanner. A preliminary analysis cannot differentiate the models well. The acquisition protocol is then extended to include a richer angular resolution of diffusion- sampling gradient directions. Compared with ex-vivo data, simpler three-compartment models emerge. Changes in diffusion behaviour and acquisition protocol are likely to have influenced the results. The second part considers models that explicitly seek to explain fibre dispersion, another potentially specific biomarker of neurological diseases. This study finds that models that capture fibre dispersion are preferred, showing the importance of modelling dispersion even in apparently coherent fibres. In the third part, we improve the methodology. First, during the data pre-processing we narrow the region of interest. Second, the model fitting takes into account the varying echo time and compartmental tissue relaxation; we also test the benefit to model performance of different compartmental diffusivities. Next, we evaluate the inter- and intra-subject reproducibility of ranking. In the fourth part, high-gradient Connectom-Skyra data are used to assess the generalisability of earlier results derived from a standard Achieva scanner. Results showed a reproducibility of major trends in the model ranking. In particular, dispersion models explain low gradient strength data best, but cannot capture Connectom signal that remains at very high b-values. The fifth part uses cross-validation and bootstrapping as complementary means to model ranking. Both methods support the previous ranking; however, the leave-one-shell-out cross- validation supports less difference between the models than bootstrapping.

The subject of this thesis are selected interest rate models and valuation of interest rate derivatives, especially interest rate options. Time-homogeneous one-factor short rate models, Vasicek and Cox-Ingersoll-Ross, and time-inhomogeneous short rate model, Hull{White, are treated. Heath-Jarrow-Morton framework is introduced as an alternative to short rate models, evolving the entire term structure of interest rates. The short rate models are shown to be special cases of models within the framework. The models are derived using the risk-neutral pricing methodology.

Abstract:
Includes bibliographical references.
A model with a stochastic interest rate process correlated to a stochastic volatility process is needed to accurately price long- dated contingent claims. Such a model should also price claims efficiently in order to allow for fast calibration. This dissertation explores the approximations for the characteristic function of the Heston-Hull&White model introduced by Grzelak and Oost- erlee (2011). Fourier-Cosine expansion pricing, due to Fang and Oosterlee (2008), is then used to price contingent claims under this model, which is implemented in MATLAB. We find that the model is efficient, accurate and has a relatively simple calibration procedure. In back-tests, it is determined that the Heston- Hull&White model produces better hedging profit and loss results than a Heston (1993) or a Black and Scholes (1973) model.

This thesis includes a brief introduction to Adjoint Algorithmic Differentiation (AAD), accompanied by numerical examples, step-by-step explanations and runtime comparisons to a finite difference method. In order to show the applicability of AAD in a stochastic setting, it is also applied in the calculation of the arbitrage free price and partial derivatives of a European call option, where the underlying stock has Geometric Brownian motion dynamics. Finally the Hull-White model is calibrated using a set of zero coupon bonds, and a set of swaptions. Using AAD, the partial derivatives of the model are found and used in a Newton-Raphson method in order to find the market's implied volatility. The end result is a Monte Carlo simulated short rate curve and its derivatives with respect to the calibration parameters, i.e. the zero coupon bond and swaption prices.
Denna uppsats innehåller en introduktion till Adjungerad Algoritmisk Differentiering (AAD), tillsammans med numeriska exempel, steg-för-steg beskrivningar samt körtidsjämförelser med en finit differensmetod. För att illustrera applicerbarheten av AAD i ett stokastiskt ramverk, tillämpas metoden i beräkningen av det arbitragefria priset och de partiella derivatorna av en europeisk köp-option, där den underliggande aktien har geometrisk Brownsk dynamik. Slutligen kalibreras Hull-White-modellen genom ett antal nollkupongsobligationer och swap-optioner. Via AAD beräknas de partiella derivatorna för modellen som sedan används i Newton-Raphsons metod för att finna markandens implicita volatilitet. Slutresultatet är en Monte Carlo-simulerad räntekurva och dess derivator med avseende på kalibreringsparametrarna, dvs. nollkupongs- och swap-optionspriserna.

Abstract:
Growing popular and industry interest in high-performing natural language generation models has led to concerns that such models could be used to generate automated disinformation at scale. This report examines the capabilities of GPT-3--a cutting-edge AI system that writes text--to analyze its potential misuse for disinformation. A model like GPT-3 may be able to help disinformation actors substantially reduce the work necessary to write disinformation while expanding its reach and potentially also its effectiveness.
