Published: July 2016

Purpose. This research focuses on the development of an applied numerical model to calculate the dynamics of atmospheric pollution in the emission of dangerous chemical substances in the event of transportation by railway. Methodology. For the numerical simulation of transport process of the dangerous chemical substance in the atmosphere the equation of convection-diffusion pollutant transport is used. This equation takes into account the effect of wind, atmospheric diffusion, the power of emission source, as well as the movement of the source of emission (depressurized tank) on the process of pollutant dispersion. When carrying out computing experiment one also takes into account the profile of the speed of the wind flow. For the numerical integration of pollutant transport in the atmosphere implicit finite-difference splitting scheme is used. The numerical calculation is divided into four steps of splitting and at each step of splitting the unknown value of the concentration of hazardous substance is determined by the explicit running account scheme. On the basis of the numerical model it was created the code using the algorithmic language FORTRAN. One conducted the computational experiments to assess the level of air pollution near the railway station «Illarionovo» in the event of a possible accident during transportation of ammonia. Findings. The proposed model allows you to quickly calculate the air pollution after the emission of chemically hazardous substance, taking into account the motion of the emission source. The model makes it possible to determine the size of the land surface pollution zones and the amount of pollutants deposited on a specific area. Using the developed numerical model it was estimated the environmental damage near the railway station «Illarionovo». Originality. One can use the numerical model to calculate the size and intensity of the chemical contamination zones after accidents on transport. Practical value. The numerical model, developed by authors, can be used to estimate the size and intensity of the chemical contamination zones during emergency on transport. The developed numerical model solves the problem of assessing the impact of emergency emission of ammonia near the railway station «Illarionovo».

Authors: Ovcharenko S. M.
Published: July 2016

Purpose. The system of train sheet analysis (TSA) in the information system of JSC «Ukrzaliznytsia» provides work with passenger and suburban trains and has considerable potential. Therefore it is necessary to establish the prospects of development of the system. Methodology. Departments’ setup and the train delay causes should be carried out at every station and span, where such delays took place. This requires the fixation of condition deviations of infrastructure from normal and other adverse factors. In the sector of freight transportations the train schedule analysis is insufficient, since this analysis does not account for deviations from the terms of delivery. Therefore it also is necessary to analyze the delivery graphs. The basis for monitoring the cargo delivery is the method of control time points (CTP) of technological operations performed with cargo at railway stations. On the basis of CTP to assess the quality of the transport process one should calculate the values of the analysis of cargo delivery schedule (performance level of the cargo delivery schedule, the coefficient of ahead of schedule/delay delivery). Findings. The article proposes to develop the system TSA using the input and display of the train delay causes on-line by transportation service employees, expansion of statistical databases and processing of the input delay causes during its calculation train sheet analysis of freight trains and quality assessment of the delivery schedule fulfillment. It is also appropriate before the new operator companies had appeared to make changes in the instructions TSCHU-TSD-0002 on the list of departments, which include delayed trains, by adding «the department» «The fault of operator companies» and corresponding causes of delays. Originality. The scheme of automated TSA in the information system of JSC «Ukrzaliznytsia» was improved. The author proposes to determine the cargo delivery quality on the certain polygon using the following levels: high, satisfactory, low and ultralow. A schedule to determine the levels of delivery quality was developed. Practical value. The implementation of the proposed solutions will improve and enhance the formation of statistical reporting of TSA in JSC «Ukrzaliznytsia».

DEPENDENCE OF AIR SPRING PARAMETERS ON THROTTLE RESISTANCE
Authors: Reidemeister O. H. , Kivisheva A. V.
Published: July 2016

Purpose. In this paper it is necessary to conduct: 1) research and analyse the influence of throttle element pneumatic resistance on elastic and damping parameters of air spring; 2) to obtain the dependence of air spring parameters on throttle element pneumatic resistance value. Methodology. The work presents the elaborated model of the air spring as a dynamic system with three phase coordinates (cylinder pressure, auxiliary reservoir pressure, cylinder air mass). Stiffness and viscosity coefficients were determined on the basis of system response to harmonic kinematic disturbance. The data for the analysis are obtained by changing the capacity of the connecting element and the law of pressure variation between the reservoir and the cylinder. The viscosity coefficient is regarded as the viscosity ratio of the hydraulic damper, which for one oscillation cycle consumes the same energy as the air spring. The process of air condition change inside the cylinder (reservoir) is considered to be adiabatic; the mass air flow through the connecting element depends on the pressure difference. Findings. We obtained the curves for spring viscosity and stiffness coefficients dependence on the throttle resistance at three different laws, linking airflow through the cylinder with the pressure difference in cylinder and reservoir. At both maximum and minimum limiting resistance values the spring viscosity tends to zero, reaching its peak in the mean resistance values. Stiffness increases monotonically with increasing resistance, tends to the limit corresponding to the absence of an auxiliary reservoir (at high resistance) and the increase in cylinder volume by the reservoir volume (at low resistance). Originality.The designed scheme allows determining the optimal parameters of elastic and damping properties of the pneumatic system as function of the throttle element air resistance. Practical value.The ability to predict the parameters of elastic and damping properties of the pneumatic system as function of the throttle element air resistance will improve the running performance of carriages, the comfort of passenger transportation and reduce the wear of the rolling stock and the track caused by interaction of carriage and rails.

Published: July 2016

Background.

The phase II YO28252 study (01590719) examined first-line onartuzumab plus mFOLFOX6 in patients with metastatic, human epidermal growth factor receptor 2-negative adenocarcinoma of the stomach or gastroesophageal junction. MET immunohistochemistry expression as a biomarker of onartuzumab activity was also examined.

Patients and Methods.

Patients were randomized 1:1 to receive standard mFOLFOX6 plus onartuzumab (10 mg/kg) or placebo in 2-week cycles for 12 cycles, followed by onartuzumab or placebo until disease progression. Coprimary endpoints were progression-free survival (PFS) in intent-to-treat (ITT) and MET-positive populations. The target hazard ratio (HR) was 0.70 for patients in the ITT group and 0.60 in the MET-positive population. Secondary endpoints were overall survival (OS), overall response rate (ORR), and safety.

Results.

Overall, 123 patients were enrolled (n = 62 onartuzumab, n = 61 placebo). Median PFS was 6.77 versus 6.97 months for onartuzumab versus placebo, respectively (HR, 1.08; 95% confidence interval [CI], 0.71–1.63; p = .71). In the MET-positive population, median PFS was 5.95 versus 6.80 months, onartuzumab versus placebo (HR, 1.38; 95% CI, 0.60–3.20; p = .45). Median OS was 10.61 months for onartuzumab versus 11.27 months for placebo) (HR, 1.06, 0.64–1.75; p = .83). In the MET-positive population, median OS was 8.51 versus 8.48 months for onartuzumab versus placebo, respectively (HR, 1.12, 95% CI, 0.45–2.78; p = .80). ORR was 60.5% for the onartuzumab group and 57.1% for placebo. Grade 3–5 adverse events (AEs) were seen in 88.3% of patients receiving onartuzumab and in 78.3% of patients receiving placebo, with serious AEs in 55% and 40%, respectively.

Conclusion.

The addition of onartuzumab to mFOLFOX6 in gastric cancer did not improve efficacy in an unselected population or in a MET immunohistochemistry-positive population.

Nephron number may be an important determinant of kidney health but has been difficult to study in living humans. We evaluated 1638 living kidney donors at Mayo Clinic (MN and AZ sites) and Cleveland Clinic. We obtained cortical volumes of both kidneys from predonation computed tomography scans. At the time of kidney transplant, we obtained and analyzed the sections of a biopsy specimen of the cortex to determine the density of both nonsclerotic and globally sclerotic glomeruli; the total number of glomeruli was estimated from cortical volume×glomerular density. Donors 18–29 years old had a mean 990,661 nonsclerotic glomeruli and 16,614 globally sclerotic glomeruli per kidney, which progressively decreased to 520,410 nonsclerotic glomeruli per kidney and increased to 141,714 globally sclerotic glomeruli per kidney in donors 70–75 years old. Between the youngest and oldest age groups, the number of nonsclerotic glomeruli decreased by 48%, whereas cortical volume decreased by only 16% and the proportion of globally sclerotic glomeruli on biopsy increased by only 15%. Clinical characteristics that independently associated with fewer nonsclerotic glomeruli were older age, shorter height, family history of ESRD, higher serum uric acid level, and lower measured GFR. The incomplete representation of nephron loss with aging by either increased glomerulosclerosis or by cortical volume decline is consistent with atrophy and reabsorption of globally sclerotic glomeruli and hypertrophy of remaining nephrons. In conclusion, lower nephron number in healthy adults associates with characteristics reflective of both lower nephron endowment at birth and subsequent loss of nephrons.
Study abroad as a context for spiritual development
Authors: Motyka Matthew , Wolcott Timothy
Published: July 2016

In this article, we consider the cases of two American undergraduates, Lola and Audrey, who studied abroad for a semester in France. Drawing on interview data collected during their sojourn, we consider their accounts of living and learning in France through the lens of Jesuit spirituality. In doing so, we demonstrate that although these students’ accounts offer little evidence of linguistic or intercultural development, their deeply personal reactions to a term abroad in France suggest a kind of beneficial identity crisis best understood in the spiritual terms of desolation, consolation, discernment, and election. Following the case studies, we apply our findings to the outline of a short-term study abroad program in France designed to maximize linguistic and spiritual development.

Two studies investigated the accuracy of eight different interval-based group observation methods that are commonly used to assess the effects of classwide interventions. In Study 1, a Microsoft Visual Basic program was created to simulate a large set of observational data. Binary data were randomly generated at the student level to represent 30–min observations using a 15-s momentary time sampling procedure for 5,000 students distributed evenly across 200 classrooms. Additionally, five classroom types were generated to determine if the base rate of behavior affected the accuracy of each method. Each of the eight observation methods were applied to the simulated data and compared to a criterion to determine their accuracy in estimating rates of classroom behavior. A two-way ANOVA identified a significant main effect for observation method, F(3.40, 663.07) = 15,824.22, p < .001, and a significant interaction between coding method and classroom composition, F(13.60, 663.07) = 40.04, p < .001. In Study 2, to replicate Study 1 using authentic observation data, we compared the accuracy of the same eight methods using a small sample of observations collected in an actual classroom. The results of both studies suggest that six of the eight methods (i.e., two Individual methods and four Planned Activity Check methods) are accurate assessments of group behavior. Furthermore, although classroom composition was associated with statistically significant differences between the accurate methods, we do not consider them large enough to be practically relevant.
Stakeholders’ Voices: Defining Needs of Students with Emotional and Behavioral Disorders Transitioning between School Settings

Students with emotional and behavioral disorders (EBD) too often do not receive adequate services or care in their school settings, particularly during transitions in educational placements. In addition, school support teams often struggle with creating transition plans that honor the needs of students with input from key stakeholders responsible for supporting student success. This article presents findings from the information-gathering phase of an iterative project that aims to develop a support program for students with EBD transitioning from day-treatment schools to district schools. We conducted 5 semistructured, qualitative focus groups with parents and teachers to explore needs during students’ transitions between school settings. Five themes emerged from the focus groups: (a) consistent, behavior-specific feedback and positive reinforcement are vital to sustaining learned prosocial skills; (b) students benefit from regular opportunities to learn and practice social skills; (c) transition programming should emphasize communication between school and home; (d) routines at home and school should be coordinated; and (e) parents need support at school meetings. We will use findings from this study to develop a multifaceted intervention that aims to support students, their caregivers, and their teachers during transitions between the aforementioned types of schools.

El sistema financiero se ha vuelto un tema de estudio de gran relevancia para las áreas económicas y financieras, las cuales buscan nuevos métodos para obtener una visión acertada en la toma de decisiones por parte de los diferentes inversionistas. Por ello, el presente documento tiene como propósito mostrar cómo la aplicación de la metodología de rango reescalado y exponente de Hurst logra analizar y determinar la persistencia y las estructuras con fenómenos irregulares (autocorrelación) dentro del mercado colombiano. Para ello, se tomaron como muestra cinco de las acciones más representativas de la bolsa de valores de Colombia y del índice Colcap (grupo Aval, Ecopetrol, Bancolombia y el grupo Éxito), así como sus rendimientos, de acuerdo con sus oscilaciones durante un periodo de cinco años. Al implementar la metodología de Rango Reescalado, se encontró que los activos analizados presentan fenómenos de persistencia y antipersistencia en las series de tiempo, lo que muestra que ninguna de las acciones se encuentra bajo el supuesto de normalidad. Por lo tanto, es necesario implementar nuevas herramientas que permitan mayor firmeza en los análisis, como pueden ser el R/S modificado, expuesto por Lo (1991) o variables que permitan determinar procesos estocásticos dentro de las series, lo cual es fundamental para brindar una mayor rigurosidad al cálculo matemático para que este apoye de una forma más eficiente a los inversionistas.
Reflexiones sobre el futuro del capitalismo siglo XXI
Authors: Gil-Bolívar Fabio Alberto
Published: July 2016

La siguiente es una reflexión crítica sobre el futuro del capitalismo, desde la perspectiva del economista francés Thomas Piketty, y, en particular, a partir de su contribución El capital en el siglo XXI (2014), que ha sido merecedora de grandes elogios por parte de la gran prensa mundial, así como de la comunidad académica internacional. Piketty aborda como tema central la creciente desigualdad de la riqueza y la naturalidad de ésta como atributo del capitalismo. Sin lugar a dudas, esta voluminosa obra es un excelente pretexto para revistar la vigencia y futuro del capitalismo como sistema económico dominante, a luz de diversas disciplinas académicas y no sólo desde la disciplina económica. El artículo comprende las siguientes secciones: Introducción; La obra de Piketty; Marco conceptual y metodología; Convergencia y divergencia; Capitalismo y desarrollo; la desigualdad, la gran amenaza del capitalismo; y el futuro del capitalismo.
Factores asociados al incumplimiento de la oferta de servicios de asistencia médica domiciliaria

Published: July 2016

El estudio exploró aspectos que permitieron analizar los factores asociados al incumplimiento de la oferta de servicios de Asistencia Médica Domiciliaria, con el propósito de proponer acciones de mejoramiento que ayuden a garantizar el cumplimiento de la promesa de valor realizada y reduzcan los riesgos para la salud de los clientes. Se realizó un estudio descriptivo, prospectivo de corte transversal, utilizando técnicas de cliente incógnito y paciente trazador, en cuatro compañías que ofertan pólizas o anexos de servicio domiciliario en Colombia, se entrevistó a tres asesores comerciales de cada Institución Objeto de Estudio para tipificar la oferta. Posteriormente, se solicitaron cinco servicios de asistencia médica domiciliaria para cada paciente, con base en motivos de consulta predeterminados y supervisados por el equipo médico. Los hallazgos arrojados en el presente estudio evidenciaron una falta de coherencia entre la promesa de valor al cliente hecha por los asesores comerciales, los contratos de servicios y la atención prestada por el personal operativo de las instituciones estudiadas, en términos de oportunidad, accesibilidad y pertinencia. De la misma manera, se evidenciaron problemas de orden ético en los profesionales de salud en la prestación del servicio y manejo del registro de historia clínica. Se generaron recomendaciones desde la óptica de la gerencia de la calidad en salud, en aras de optimizar la coherencia entre los servicios ofertados y el servicio prestado en el campo de atención médica domiciliaria en beneficio del paciente y el sistema de salud colombiano.

Moment Varieties of Gaussian Mixtures

Published: July 2016

The points of a moment variety are the vectors of all moments up to some order, for a givenfamily of probability distributions. We study the moment varieties for mixtures of multivariate Gaussians.Following up on Pearson's classical work from 1894, we apply current tools from computational algebrato recover the parameters from the moments. Our moment varieties extend objects familiar to algebraicgeometers. For instance, the secant varieties of Veronese varieties are the loci obtained by setting allcovariance matrices to zero. We compute the ideals of the 5-dimensional moment varieties representingmixtures of two univariate Gaussians, and we oer a comparison to the maximum likelihood approach.
On multivariable cumulant polynomial sequences with applications
Authors: Di Nardo Elvira
Published: July 2016

A new family of polynomials, called cumulant polynomial sequence, and its extension to the multivariate case is introduced relied on a purely symbolic combinatorial method. The coefficients are cumulants, but depending on what is plugged in the indeterminates, moment se- quences can be recovered as well. The main tool is a formal generalization of random sums,  when a not necessarily integer-valued multivariate random index is considered. Applications are given within parameter estimations, L\'evy processes and random matrices and, more generally, problems involving multivariate functions. The connection between exponential models and multivariable Sheffer polynomial sequences offers a different viewpoint in employing the method. Some open problems end the paper.
