Authors: Nwajinka C. O. , Nwanna E. C. , Ogbu K. N.
Published: December 2019

Physico-chemical and bacteriological characteristics of borehole water in seven communities in Anambra State were investigated to ascertain their portability and evaluate their pollution levels for household consumption. Obtained sample results were compared with threshold values reported by World Health Organization (WHO) for drinking water purposes. Study results show that values for total hardness, lead, copper, zinc, iron and coliform count exceeded the WHO thresholds and as such made this resource unfit for human consumption. It is recommended that the state water board be revamped and its branches established in all communities of the state to ensure regulation and control of the water household water supplies.

Authors: Li Li , Zhong Peilin , Xiao Yao , Wu Hsin-Hung , Huang Chih-Husan
Published: December 2019

Creating a better patient safety culture in hospitals has become a critical topic for providing quality medical services globally. In 2014, there were 115 thousand cases of medical disputes in China. Understanding physiciansâ€™ perceptions toward patient safety is a critical issue for hospitals to monitor safety situations for patients. This study aims to identify physiciansâ€™ attitudes toward patient safety via the investigation of Sexton et al. (2006)â€™s Safety Attitude Questionnaire (SAQ), to provide implications for improving medical quality. Pearsonâ€™s correlation analysis was used to demonstrate the relationships among six patient safety culture dimensions. Regression analysis was subsequently conducted to realize the degree of influence among important dimensions. Physicians was asked to answer the SAQ in a tertiary hospital in China in 2017. The results of Pearson correlation analysis demonstrate that safety climate had strong and positive relationship with working conditions and teamwork climate, respectively. Similarly, regression results illustrated that working conditions, teamwork climate, and teamwork climate had noteworthy effects on safety climate. The examination of patient safety culture from the viewpoints of physicians provides a basis for hospital managers to monitor the medical quality and service for patients. Hospital managers need to pay more efforts to the essentially important elements of patient safety, such as working conditions, teamwork climate, and job satisfaction, to continuously improve physician-patient relationship.Â
Smart Farm with Foodborne Pathogen Monitoring
Authors: Lok Daeun , Wright Timothy , Bhagchandani Mayank , Litvinchuk Darya
Published: December 2019

Conventional agriculture uses data about real-time climatic conditions, soil (texture, depth, nitrogen levels), illumination, topography, moisture, etc. to make appropriate decisions with regards to sowing, watering, fertilizing, pesticide-treating and harvesting.Â  However, it does not have a system to monitor pathogens and collect data on the amount of pathogens present in various abiotic factors (e.g. water, soil).Â  Due to the absence of effective techniques in detecting pathogen contamination at the farm or field level, it is currently difficult to deter a food related illness and outbreak once contamination has been introduced. The purpose of this research is to help identify contamination hazards at the farm using biosensors to detect pathogens in potential sources of contamination, such as water, soil, manure, and air. By adopting Internet of Things (IoT) connectivity, a simple farm can be turned into a smart farm.Â  The objective of a smart farm is to prevent threats to the farming and food industry by monitoring pathogen levels and using real-time alerts to warn applicable stakeholders when established thresholds have been surpassed.

The purpose of this study was to examine the effect of return on equity on the dividend payout ratio, the effect of the company's growth on the dividend payout ratio, the effect of free cash flow on the dividend payout ratio, the effect of leverage on the dividend payout ratio, and the effect of the dividend payout ratio on firm value. The model used in data analysis is a simple multiple regression model because the measurement of the dependent and independent variables in this study is in the form of numbers with a ratio scale measurement instrument and independent variables used by more than one. The results of this study indicate that the return on equity has a significant effect on the dividend payout ratio, growth has no significant effect on the dividend payout ratio, free cash flow has a significant effect on dividend payout ratio, leverage has no significant effect on the dividend payout ratio, and dividend payout ratio has a significant effect on the value of the company.
Do Accounting Programs at Saudi Universities Adopt Relevant Skills?
Authors: Zureigat Qasim
Published: December 2019

This study aims at investigating wither accounting programs at Saudi universities incorporate relevant skills into its curriculum or not. The study utilizes International Educational Standards (IES), mainly standard 3 to identify the relevant skills for accounting graduates, as these standards represent internationally accepted standards for accounting education. Based on IES 3 structure and components, a questionnaire was developed and distributed to Saudi universities that offer accounting programs, and a total number of 111 questionnaires were revealed and analyzed. The results indicated that Saudi universities incorporate intellectual skills, technical and functional skills and interpersonal and communication skills into the curriculum of its accounting programs, while these programs lack both personal skills and organizational and business management skills. Such results support the lack of a comprehensive framework at Saudi universities for its accounting programs. The study recommends universities and regulators to deeply assess accounting programs at Saudi universities and to redesign its curriculum to meet the need for skilled and qualified accountants.

Published: December 2019

Teaching computer programming to novice programmers is a challenging job. One possible reason for this is that novice programmers struggle to understand internal manipulation of key programming concepts which causes misconception and difficulties. An observation study was conducted to investigate misconceptions and difficulty experienced by Novice Programmers. Study revealed three major findings - firstly, novice programmers found textual presentation of programming concept to be monotonous; they preferred alternative presentation in the form of â€“ text, audio, video, animation, simulation etc. Secondly, Ergonomics of learning interface causes eye fatigue. Thirdly, to remove misconception when novice programmers search WWW due to numerous search results they suffer from â€˜lost-in-hyperspaceâ€™ problem.Further, exhaustive survey on existing integrated programming IDE (C, C++, Java Editor, .net Editor, SQL Server, Oracle) revealed integrated help provided by majority of them, suffers from key findings of observational study. To address this, â€œIntegrated Helpâ€ content presentation model is proposed. A series of studies established this model to be potentially effective. Learning material facilitated through â€œIntegrated Helpâ€ was found to interesting and engaging. As a result it proved to be an aid to novice programmers to develop better understanding of key concepts.Â

Correlation for Predicting Water Breakthrough Time in Thin Oil Rim Reservoirs in the Niger Delta
Authors: Okon Anietie , Appah Dulu , Akpabio Julius
Published: December 2019

In the Niger Delta, available correlations to predict water breakthrough time in thin oil rim reservoirs are based on generic reservoir models and/or experimental design approach. This approach had not considered the heterogeneity of the reservoir. Thus, the prediction of these available correlations for thin oil rim reservoirs in the Niger Delta is in doubt, considering the sensitive nature of developing thin oil rim reservoirs. Then, a correlation for water breakthrough time (tbt) was developed based on integrated reservoir model of thin oil rim reservoir in the Niger Delta. The obtained result indicated that the developed correlation predicted 1652.72 days compared to the actual Oilfield breakthrough time of 1653 days (about 4.53 years). Also, sensitivity study showed that the developed correlation and the integrated reservoir model predictions of oil production rate (qo), fractional well penetration (hp/h) and height above perforation-oil column (hap/h) on the water breakthrough time (tbt) were close and resulted in coefficient of determination (R2) of 0.9697, 0.8597 and 0.9553, respectively. Furthermore, the results depicted that water coning breakthrough time (tbt) depends directly on oil production rate (q) and well completion parameters: fractional well penetration (hp/h) and height above perforation (hap). Hence, to delay early water breakthrough in thin oil rim reservoirs, these completion parameters are consideration in vertical wells to achieve optimum oil recovery. Also, the developed correlation can be used as a quick and robust tool to predict water breakthrough time of thin oil rim reservoirs in the Niger Delta.

Published: December 2019

This paper investigates â€œDivorce: Causes and Effects on Children.â€ Worthy of note is that the fact that, divorce is not an uncommon experience in human history. It is experienced by couples irrespective of their social, religious, academic, political, economic, etc. status. One of the most hit in the saga of divorce are children born into the wedlock where divorce is experienced. The effects of this divorce on children are most often not well considered by the parents who embark on taking the status of divorcees. This becomes the onus of this paper using sociological and psychoanalytical approaches to the study of human institutions to study these effects on children, though not without looking at the causes of divorce. The paper reveals that the effects of divorce on children often are emotional, psychological, economical and religious spheres among others and recommends ways in which these effects can be minimized among children.

In cognitive science, the psychological and biological foundations of music are often considered in the context of comparison with the functions of speech and language. The article describes some aspects of the similarities and differences between music and speech in the implementation of language functions, as well as a typological study of its features according to Buhler, Jakobson, Halliday and Kiklewicz classifications. A general comparison of structural organization and main perceptual characteristics of music and speech signals is carried out additionally, with separate consideration of neurophysiological foundations of the auditory analysis of timbre characteristics of speech sources (speaker's voice) and music (instrument sounds). Some aspects of the practical application of auditory and musical training in the context of training and rehabilitation measures for sensory-cognitive dysfunctions of various genesis are explained, with the prospects of further research aimed at studying the influence of the timbre on the indices of spatial selectivity of musical perception in comparison with the characteristics of the spatial selectivity of speech hearing in the perception of complex acoustic scenes.

Published: December 2019

Objective: Cardiac pacemaker records atrial fibrillation (AF). This condition can cause serious hemodynamic consequences to patients, who should be assisted by a cardiologist. This study aimed to document and investigate, in a tertiary hospital, the prevalence of subclinical AF in patients with a cardiac pacemaker. Methods: Between July 2015 and April 2016, 196 patients with pacemakers were attended on an outpatient basis. Of these, 60 had cardiac arrhythmias recorded by the pacemaker and were invited to participate in the study. Data collection was done through a structured interview containing four questions: gender, age, follow-up with cardiologist and use of anticoagulants. Results: Subclinical AF was recorded in 35 (17.8%) of the total of 196 patients. Of these 35, 16 (45.7%) did not follow a regular cardiology service and 29 (82.8%) did not use anticoagulant medication. No statistically significant relationships were found between age, follow up with a cardiologist, and presence or absence of subclinical AF in the patients studied. Conclusion: A significant portion of outpatient patients with pacemakers have AF recorded by the device. However, although essential, almost half of these do not proceed with the clinical follow-up with cardiologist and less than a fifth with AF makes use of anticoagulant therapy.

CICLO DE TALLERES DE LA DIVISIÃ?N ARQUEOLOGÍAMuseo de La Plata, Facultad de Ciencias Naturales y Museo Taller V:Interacciones humanas a través del espacio en arqueología:aportes teórico-metodológicos y casos de estudio  Las investigaciones arqueológicas que desarrollamos, más allá de las distintas áreas donde las realizamos, o los materiales con los que usualmente trabajamos, implican en todos los casos el estudio de relaciones e interacciones a través del espacio entre distintos grupos humanos del pasado. Desde cualquier perspectiva teórica o abordaje metodológico, indagar en las interacciones humanas involucra necesariamente pensar, discutir e interpretar la circulación de personas, objetos e ideas a distintas escalas espaciales. Estas interacciones pueden implicar contactos directos o estar mediadas por puntos o nodos que enlazan a la vez puntos distantes a través de un trayecto. Por otra parte, algunas pueden ser muy evidentes en el registro arqueológico ?como ciertos ítems de procedencia claramente conocida encontrados a gran distancia de su fuente o lugar de origen? mientras que otras se manifiestan de formas más sutiles, como los motivos rupestres.Si bien estas ideas generales incluyen prácticamente a la totalidad de los problemas arqueológicos, si revisamos los diferentes enfoques analíticos de los estudios en nuestro propio ámbito, comprobamos que existe una amplia gama de términos que hacen referencia a interacciones de distinto tipo: redes, intercambio, circulación, movilidad, rutas, caminos, caravanas, distancias cortas, medias y/o largas, entre otros. Muchos de estos conceptos están solapados entre sí, otros son empleados como sinónimos, quizás sin una profundización en cuanto a sus definiciones.A partir de lo planteado en los párrafos anteriores, y en el marco del ciclo de talleres de la División Arqueología del Museo de La Plata, teniendo en cuenta tanto la generalidad de la temática expuesta -el estudio de las relaciones o interacciones a través de los espacios o paisajes en el pasado-, como la diversidad de enfoques que adoptamos y de problemas que enfrentamos en arqueología, proponemos la presentación por  quienes conforman el área de Antropología de la Facultad de Ciencias Naturales y Museo, acerca de cómo construyen y desarrollan los diferentes abordajes teóricos y metodológicos para estos temas desde sus respectivas áreas de trabajo, así como también resultados y síntesis  de las investigaciones sobre las interacciones a través del espacio en el registro arqueológico. Organizadores:    División Arqueología del Museo de La Plata.    Dr. Federico Wynveldt.

Em 1966 começa no Peru o Proyecto Experimental de Vivienda que, considerado como representativo da problemática de habitação dos países em vias de desenvolvimento, recebeu apoio econômico da Organização das Nações Unidas. A partir de então, é realizado um concurso envolvendo equipes internacionais e peruanas para o projeto de urbanização de 1.500 unidades que deveria contemplar investigações de tipologias habitacionais flexíveis e com possibilidades de crescimento. Este artigo analisa o projeto da “equipe francesa” formada pelos arquitetos Georges Candilis, Alex Josic e Shadrach Woods, considerando-o como uma oportunidade de síntese de uma experiência projetual e teórica de mais de 10 anos. A análise é realizada tendo como pano de fundo tanto o contexto de crítica à cidade funcionalista e à Carta de Atenas proposta nos Congressos Internacionais de Arquitetura Moderna, como o questionamento do conceito desenvolvimentista envolvendo a construção de grandes conjuntos habitacionais desde os anos cinquenta na Europa e América Latina.

A escolha por novas espécies de objetos urbanos, como o famoso “Minhocão”, um importante eixo viário em viaduto construído na década de 1970, em São Paulo, profundamente marcado de controvérsias, fundamentará a prescrição provocativa deste artigo. O objetivo é alçar as bases para a reflexão de uma perspectiva contemporânea para o campo projetivo que vislumbre outras potencialidades conceituais, alicerçando o caráter do projeto a fim de desenredar e trazer à luz as categorias e os modelos ocultos em termos dos quais algumas concepções se assentam, revelando o que é obscuro ou contraditório neles. Para tanto, parte-se de uma leitura metaprojetual que oferece subsídios para um pensamento arquitetônico que não apenas anteveja a aleatoriedade, mas que trabalhe com ela, gerenciando melhor os seus riscos. O resultado presume que a paisagem a ser estimada é aquela que vai além da fixidez equilibrada de um retrato passado ou de sua importância arquitetônica e cultural, ao reconhecer a paisagem entrópica como potência criadora, como suporte emergente dos vínculos passados e futuros.

Effects of Non-Uniform Heat Generation/Absorption and Radiation on Hydromagnetic Dissipative Flow over a Porous Nonlinear Stretching Surface with Heat and Mass Fluxes
Authors: Devi S.P. Anjali , Agneeshwari M.
Published: December 2019

Forced convective heat and mass transfer flow of hydromagnetic, radiating and dissipative fluid over a porous nonlinear stretching sheet in the presence of non-uniform heat generation/absorption is investigated numerically. The system of nonlinear partial differential equations governing the physical problem is reduced to nonlinear ordinary differential equations by means of suitable similarity transformations and are solved numerically using Nachtsheim Swigert shooting iteration scheme together with fourth order Runge Kutta method. The effects of various physical parameters on velocity, temperature and concentration distributions are depicted graphically. The important findings of this study exhibited that the effect of non-uniform heat generation/absorption parameter and radiation parameter have significant role in controlling thermal boundary layer thickness and temperature. Numerical values of the skin friction coefficient, temperature and concentration at the wall are shown in a tabular form. A comparison is made with previously published data which results in good agreement.
Water Wave Scattering by an Infinite Step in the Presence of an Ice-Cover
Authors: Ray S. , De S. , Mandal B.N.
Published: December 2019

The classical problem of water wave scattering by an infinite step in deep water with a free surface is extended here with an ice-cover modelled as a thin uniform elastic plate. The step exists between regions of finite and infinite depths and waves are incident either from the infinite or from the finite depth water region. Each problem is reduced to an integral equation involving the horizontal component of velocity across the cut above the step. The integral equation is solved numerically using the Galerkin approximation in terms of simple polynomial multiplied by an appropriate weight function whose form is dictated by the behaviour of the fluid velocity near the edge of the step. The reflection and transmission coefficients are obtained approximately and their numerical estimates are seen to satisfy the energy identity. These are also depicted graphically against thenon-dimensional frequency parameter for various ice-cover parameters in a number of figures. In the absence of ice-cover, the results for the free surface are recovered.

La maestra y el maestro investigador: reconstructores de sentido e identidad
Authors: Mejía Jiménez Marco Raúl
Published: December 2019

En este desencuentro, muy propio de la cultura occidental, ubica Maturana las dificultades de una idea de ciencia que lleva a aceptar las explicaciones científicas en una forma reduccionista, en cuanto se cree que expresan el fenómeno que se investiga en lo fundamental, teniendo la creencia de que su validez depende de las referencias directas o indirectas a una realidad objetiva en la cual el observador es independiente de ella.

Este hecho hace que, en muchas investigaciones, el carácter generativo de las explicaciones científicas, no sea visto porque quienes investigan están bajo la creencia implícita o explícita de una validez fundada en la objetividad, en donde afirmaciones y explicaciones son válidas por hacerse sobre una realidad que es independiente del sujeto que las hace.

Uma boa gestão de estoques é importante para reduzir os custos e aumentar os lucros, já que mantê-los na quantidade correta garante o atendimento da demanda e diminui o capital investido. Com base nesta visão e em teorias de autores como Dias (2009), Francischini e Gurgel (2009) e Gonçalves (2004), o objetivo deste trabalho consiste em analisar os processos, ferramentas e ações de administração de materiais utilizadas por microempresas de uma cidade de pequeno porte. O método utilizado configurou-se por meio de uma pesquisa descritiva de natureza qualitativa. Para coleta dos dados foi aplicado um questionário com vinte e três perguntas de natureza dissertativa a gestores de empresas sobre a maneira como administram seus recursos materiais. A análise foi feita por agrupamento de semelhança de respostas. O objetivo da pesquisa foi atingido, visto ter sido possível observar que as empresas pesquisadas utilizam de forma modesta, mas com alguma eficácia os métodos e ferramentas preconizados como adequados pelas teorias abordadas. No entanto, alguns métodos e ferramentas ainda poderiam ser adotados para gerar maior eficácia da gestão dos recursos materiais destas organizações.
The Minimum Wage and the Labor Market
Authors: Rocheteau Guillaume , Tasci Murat
Published: December 2019

The federal minimum wage was established in 1938 by the Fair Labor Standards Act. Initially set at 25 cents an hour, the wage has been raised periodically to reflect changes in inflation and productivity. From September 1997 to the beginning of 2007, the minimum wage stood at $5.15 an hour, but its real value declined steadily from about 40 percent of the average private nonsupervisory wage to a mere 30 percent. Adjusted for inflation, the minimum wage was lower at the beginning of 2007 than at any time since 1955 (see figure 1). Meanwhile, the wage affected fewer people, as the fraction of hourly workers who earned no more than the minimum dropped from around 15 percent in 1980 to just 2.2 percent in 2006. On May 24, 2007, Congress passed a bill raising the federal minimum wage to $7.25 in three phases over two years.

Проведено исследование проводимости трех типов композитов, полученных на основе полиэтилена (ПЭ) и многослойных углеродных нанотрубок (МУНТ) со средним диаметром 9.8 нм и аспектным отношением ~3000, 112, 36 путем механического смешения в расплаве. Структура данных композитов исследована методами оптической и растровой электронной микроскопии, рентгенофазовым анализом. С использованием циклических измерений вольт-амперных характеристик (ВАХ) и 3-точечной схемы измерений установлено, что плотность тока, пропущенного через композит, нелинейно увеличивается с ростом приложенного напряжения, а также для одного и того же напряжения при последовательном измерении ВАХ. На основании результатов измерения ВАХ определены концентрационные зависимости проводимости и их изменение для каждого типа МУНТ. Определено, что при получении композитов путем механического смешения в расплаве порог перколяции МУНТ, определяемый по третьему измерению ВАХ, снижается с уменьшением аспектного отношения нанотрубок в диапазоне 3000—36.

Introduction: self-efficacy for the control of alcohol consumption is a relevant variable in addiction intervention programs. The Brief Situational Confidence Questionnaire (CBCS) was developed for adult problem drinkers in Canada and subsequently included in intervention programs for adults and adolescents in Mexico. Although, the only data reported in our country has been its internal consistency index. Therefore, it was proposed to evaluate whether the questionnaire had similar psychometric characteristics, as previously reported with Canadian adults, with Mexican college students. Objective: obtain the validity and reliability of the CBCS with Mexican students. Method: 1,175 university volunteers, alcohol consumers in the last year and who reported two or more indicators for DSM 5 alcohol use disorder. The evaluation followed the standards for the development and review of instrumental studies. Results: the confirmatory factor analysis yielded a final model of a single dimension of four reagents: testing control over consumption, physical need, conflicts with others and pleasant moments with others, with an internal consistency index of .78. Discussion and conclusions: unlike what was found with adult problem drinkers, in this work a questionnaire composed of a single dimension was obtained, possibly due to the characteristics of the population, with an acceptable level of reliability. The questionnaire can be used in intervention programs or in studies that measure the situational self-efficacy for alcohol consumption in Mexican university students.

El presente estudio de caso, tiene el objetivo de  realizar una propuesta de correcciones a las desviaciones operacionales de una PyME en el Estado de Hidalgo, México del sector industrial, alineando sus prácticas con lineamientos estipulados en los Estándares Internacionales de Auditoría (ISA por sus siglas en inglés) específicamente de la norma 315. Se realizaron análisis estadísticos con información obtenida de la aplicación de un cuestionario para conocer la percepción de la plantilla laboral en seis esferas de la empresa las cuáles han sido divididas en los rubros: condiciones de trabajo, organización del trabajo, comunicación, concertación y coordinación, gestión del tiempo, formación integrada e implementación estratégica. Los resultados permitieron identificar áreas de oportunidad que nos dieron la pauta para formular propuestas desarrolladas con un enfoque basado en la normatividad de auditoría aplicable.
