FLOW OVER TIME PROBLEM WITH INFLOW-DEPENDENT TRANSIT TIMES
Authors: Khanal Durga Prasad , Pyakurel Urmila , Dhamala Tanka Nath
Published: January 2019

Network flow over time is an important area for the researcher relating to the traffic assignment problem. Transmission times of the vehicles directly depend on the number of vehicles entering the road. Flow over time with fixed transit times can be solved by using classical (static) flow algorithms in a corresponding time expanded network which is not exactly applicable for flow over time with inflow dependent transit times. In this paper we discuss the time expanded graph for inflow-dependent transit times and non-existence of earliest arrival flow on it. Flow over time with inflow-dependent transit times are turned to inflow-preserving flow by pushing the flow from slower arc to the fast flow carrying arc. We gave an example to show that time horizon of quickest flow in bow graph GB was strictly smaller than time horizon of any inflow-preserving flow over time in GB satisfying the same demand. The relaxation in the modified bow graph turns the problem into the linear programming problem.
BEAT FREQUENCY AND VELOCITY VARIATION OF IONS IN A MAGNETIZED PLASMA SHEATH FOR DIFFERENT OBLIQUENESS OF THE MAGNETIC FIELD
Authors: Adhikari B. R. , Basnet S. , Lamichhane H. P. , Khanal R.
Published: January 2019

Beat frequency and velocity variation of ions in a magnetized plasma sheath has been numerically investigated by using a kinetic trajectory simulation (KTS) model for varying obliqueness of the external magnetic field in presence of an electric field. Angular dependence of mean value, maximum amplitude, damping constant, frequency of oscillation and beat frequency have been studied. As the obliqueness of the field changes the mean values, beat frequency as well as the maximum amplitude of the velocity components also change but frequency of oscillation remains almost the same.

Authors: Markunas Marisa
Published: January 2019

Conhecer o percurso da formação de atletas e o desenvolvimento do papel profissional, explicitando e discutindo possíveis contribuições da psicologia do esporte foi objetivo do presente estudo. Foram tomados como metodologia de investigação os preceitos do Psicodrama, a partir da Teoria de Papéis, ao estudar o imaginário sobre ‘o que é ser atleta’ em encontros realizados com três grupos de jovens atletas de uma instituição particular de formação de atletas. Após este levantamento, foram analisadas as diferenças em três momentos do desenvolvimento esportivo (iniciantes na modalidade, praticantes e atletas juvenis), resultando na construção de uma análise da formação do papel profissional de atletas, em que se compreende que as crianças ingressam no contexto esportivo na Fase Role Taking, e ao prosseguirem em instituições de formação de atletas passam pelo Role Playing, culminando com o Role Creating quando chegam às categorias adultas-principais da sua modalidade.
Investigação do medo no contexto esportivo: necessidades do treinamento psicológico
Authors: Lavoura Tiago Nicola , Machado Afonso Antonio
Published: January 2019

Por meio de uma pesquisa qualitativa, utilizando-se a técnica de história de vida e análise de conteúdo temático, este trabalho teve o objetivo de investigar as situações ou acontecimentos que podem desencadear nos atletas o sentimento de medo, como tais indivíduos reconhecem tal sentimento em seus contextos esportivos, e lidam com ele para que o mesmo não prejudique ou interfira na performance esportiva. Participaram deste estudo 10 indivíduos das modalidades mountain bike e canoagem. Nesta pesquisa, evidencia-se que o medo é uma emoção que, constantemente, se faz presente no contexto esportivo, recebendo diferentes representações e interpretações dos atores sociais, assim como a grande diversidade e complexidade dos estados emocionais, na prática esportiva, entendendo-se que, quanto maior sua exigência, quanto maior o nível de desempenho exigido dos atletas, maior a dinâmica destes estados afetivos, e a sua influência na performance dos mesmos.

Authors: Filgueiras Alberto
Published: January 2019

Imagery can be defined as a human capacity of mentally rehearse and reproduce a skill. The use of imagery techniques is common among athletes. To contribute with sport psychologists on the quantitative assessment of mental training based on Allan Paivio’s model, this study aims to translate, adapt and assess content validity of the Sport Imagery Questionnaire in Brazil. The process of adaptation followed the guidelines of the International Test Commission. Three independent translators translated to Brazilian Portuguese; then the synthesis of those items produced the first version of the instrument that was back-translated to English. This first version in Brazilian Portuguese with the original and back-translated versions in English were sent to four bilingual sport psychology specialists. Content Validity Coefficient was used to evaluate cultural adequacy, understanding and quality of translation of each item and the questionnaire. Results showed an average CVC of 0,88 for adequacy, 0,87 for understanding and 0,85 for quality of translation among items and a CVC of 0,88 for the scale as a whole. Obtained data was discussed through the light of sports practice and culture in Brazil.

Authors: Rubio Katia , Costa Márcia Regina Lima , Lima Luciana Tabarini
Published: January 2019

A dor é uma presença constante na vida de atletas profissionais. Resultado do uso do corpo em seu limite a dor deixa de ser um sinal de alerta para ser uma condição permanente indicando altos níveis de demanda física e emocional. A essa dor, denominada dor do treinamento, pouca importância é dada pelo atleta e comissão técnica. No entanto, quando se apresenta uma lesão que impede o exercício profissional manifesto em treinamento e competições, uma nova conduta deve ser adotada para o pronto restabelecimento. A dor da lesão demanda cuidados específicos da equipe de saúde que trabalha com o atleta para que a adesão ao processo de reabilitação ocorra de forma eficiente, respeitando as necessidades do atleta. Esse artigo consiste de uma revisão de literatura acerca da dor e da importância dos cuidados da equipe de reabilitação com atletas

Authors: Plácido Thaís Teixeira , Medeiros Carlos Augusto de , Cruz Gleidson Gabriel da
Published: January 2019

Participaram da pesquisa duas crianças e um adolescente que apresentavam diagnóstico de autismo. Foi investigado, a partir de uma tarefa de Matching to Sample (MTS), o efeito de regras gerais e específicas sobre a correspondência verbal fazer-dizer. Após cada tentativa do MTS, os participantes tinham que relatar se haviam acertado ou não a tentativa. As consequências aos relatos de acertos foram manipuladas em três condições experimentais: linha de base, reforçamento para relatos de acertos, reforçamento de relatos correspondentes e retorno à linha de base. As condições com reforçamento de relatos de acertos foram divididas em sem instrução e com instrução geral, que sinalizava a relação  comportamento/consequências, e instrução específica, que sinalizava a relação ocasião/comportamento/consequência. As distorções foram muito mais numerosas nos relatos de erros e não variaram em função das condições experimentais. Houve variabilidade entre os participantes, mas, no geral, os resultados acompanharam a literatura com participantes típicos.

Age and forming conditions of groundwater in the middle Pliocene aquifer in the Mekong Delta, Vietnam, based on the results of carbon radioactive isotope study
Authors: Lam Hoang Quoc Viet , Lisenkov A. B. , Lavrushin V. J. , Belov K. V.
Published: January 2019

The results of studying and assessment of the impact of climate change on the groundwater in the Mekong delta have indicated that the exploitation of quaternary aquifers is not enough to solve the task of water supply in the region. Therefore, in the exploitation plan of groundwater in the Mekong Delta, the greatest prospects are bound with Pliocene aquifers. So, by using of carbon radioactive isotope to determine the age and forming conditions of groundwater in the middle Pliocene aquifer in the Mekong Delta, the important information for planning exploitation and zoning of areas subject to restrained exploitation of groundwater is retrieved. The determination of the age with the use of carbon radioactive isotope study in the complex with the geostatistical interpolation techniques allowed creation age map of middle-Pliocene aquifer with high accuracy nad determination the recharge area on the north-east of the Mekong delta (South-Eastern area). From the recharge area, groundwater flows in the south-west direction at a flow velocity of 8 m/year and discharges into the sea (Siam Golf and Eastern sea). It is the first time by using geostatistical interpolation «cokriging» of two parameters (age - key parameter and depth of sampling - extra parameter). The tasks to improve the accuracy of specialized maps in Vietnam have been solved. The age map has been made with the correlation parameter 0,9, that justifies the high efficiency of the studies. Furthermore, results of the correlation between age and concentration chlorine of groundwater in the middle-Pliocene aquifer (n22) allowed making a suggestion, that formation of mineralized water is a result of mixing of meteoric water with the sedimentation waters of initial sea genesis, which were formed during Flandrian transgression which began about 21000 years ago and ended 4200 years ago.

There are now a lot of distributed generation (DG) using asynchronous machines are connected to power distribution grid. These machines do not usually generate reactive power, even consume reactive power, so they generally affect the voltage stability of whole power grid, and can cause instability in itself it is no longer balanced by the torque to work. In this paper, we investigate the voltage stability problem of the asynchronous machine of wind turbines used in power distribution networks. From the static model of the asynchronous machine, this paper will apply the pragmatic criteria to analysis the voltage stability of the asynchronous machine based on the results of the power flow in power distribution network.

HO CHI MINH CITY ECONOMY IN RELATION TO THE VIETNAMESE ECONOMY AND FACTORS AFFECTING HO CHI MINH CITY ECONOMIC GROWTH
Authors: Thi Canh Nguyen , Quoc Tuan Nguyen
Published: January 2019

This research paper is focused on analyzing situation of economic development in Ho Chi Minh City after nearly 30 years implementing economic reform policies in Vietnam to specify the position and role of Ho Chi Minh City economy in comparison with the whole nation’s. In this research, we applied qualitative method with data description and economic development indicators comparison. Data are secondary data which were obtained from Statistic Yearbooks of Vietnam and Ho Chi Minh City in periods 1990/2000/2005-2013. Results indicate that the Ho Chi Minh City economy remains the Vietnam’s largest which accounts for more than 20% GDP and a third of the national budget. The annual economic growth and average income per capita are 2-3% and two times higher than those of Vietnam respectively. The poverty rate is also the lowest in the country. Factors that positively affect the Ho Chi Minh City economic growth are capital and labor as reflected by higher productivity and efficiency (specifically Ho Chi Minh City’s ICOR is 1.5-1.78 times lower than Vietnam’s and laborproductivity is two times higher than that of Vietnam) and the greater contribution of the capital and labor factors to the economic growth. However, there are signals that Ho Chi Minh City economic growth is unsustainable, including (1) slower export volume and FDI; (2) reduced weight of industry sector, especially the slow growth of key high-technology disciplines; (3) the downgrading of the urban environment quality which reduces the green GDP growth; and (4) the gradual decrease of the total factor productivity (TFP) and its very small contribution to the Ho Chi Minh City economic growth. Based on the results, this paper suggests some solutions to a sustainable development for Ho Chi Minh City in the next period.

Empirical evidence about
differences in human resource conditions between innovation- and
imitation-based economies
Authors: Csugány Julianna
Published: January 2019

The income and technological inequalities between countries can be derived from differences in country-specific conditions of technological progress. Innovation requires appropriate human resources and institutional environment, as well as firms to innovate. Differences in human, financial and institutional conditions create technology disparities which lead to innovation- and imitation-based economies with different economic performance. Technological changes in the economy are made possible by the creation and application of new knowledge. Therefore, technological progress can be interpreted as a specific form of knowledge accumulation, in which the human resources of the countries play a key role. This research aims to illustrate the inequalities of innovation’s human resource conditions between innovation- and imitation-based economies based on non-parametric and multivariate statistical methods. Variables from the human capital and research pillar of the Global Innovation Index will be compared using different analytical techniques to highlight where the bigger gaps in human resource conditions between country groups are. The main result of this research is that school life expectancy is the factor in which the countries are the most differentiated, so increasing participation in education is important for imitator countries to catch-up with innovation leaders.

نحو رؤيا استراتيجية لبناء القدرة التنافسية للاقتصاد والصناعة في العراق
Authors: صالح ربيع خلف , رشيد ثائر محمود
Published: January 2019

استهدفت هذه الدراسة تحليل واقع الاقتصاد العراقي على خلفية تحليل القدرة التنافسية بما يفضي الى وضع ملامح عامة لإستراتيجية بناء للقدرة التنافسية الوطنية للنهوض بالواقع الاقتصادي. وقد افترضت الدراسة ان الاقتصاد العراقي يعاني من اخفاقات شديدة في الاداء لا تتصل بطبيعته ولاتعتبر سمة اصيلة من سماته  بل هي ظرفية وطارئة رغم وجودها منذ عقود.

ان حالة الوهن المرافق للفعاليات الاقتصادية تتصل بغياب رؤية استراتيجية طويلة الاجل للنهوض بهذه الفعالية لمستويات تنافسية متماسكة العناصر والمرتكزات القائمة عليها، حيث اصبحت نظرية التجارة الحرة الكلاسيكية وهما بكل المقاييس لعدم تحقق الفرض الأساسي الذي تقوم عليه النظرية (المنافسة التامة) لأسباب عديدة لعل اهمها المتغير التكنولوجي العسير على كثير من الدول اضافة لتكلفة الاستثمار العالية.

وبالتالي وفي ظل اقتصاد هذا السوق غير الكامل تلعب السياسات دورا كبيرا في تحديد القدرة التنافسية والتغلب على اخفاقات السوق وتحقيق التوازن من خلال مؤشرات وركائز تقسم الى ثلاث مراحل، تتصل الاولى بالمتطلبات الاساسية ثم مرحلة الكفاءة وصولا الى مرحلة المعرفة والابتكار، وكل ذلك في ظل سلوك يتحكم بالاستثمار الاجنبي المباشر لتنمية القدرات الوطنية والتناغم مع الاستراتيجات التنموية.

لقد شهدت العقود الخمسة المنصرمة تشوها مستمرا في هيكل الاقتصاد العراقي بسبب الاحداث السياسية والعسكرية التي تخللتها فضلا عن تداعيات المرض الهولندي والسياسات الاقتصادية الخاطئة التي تبنتها الحكومات المتعاقبة.

وفي محاولة مبسطة فقد استطلعت الدراسة اراء عينة صغيرة من وحدات الاعمال في العراق (باستثناء كردستان) حول 12 مرتكزا للتنافسية وظهر ان الاقتصاد العراقي يعاني من اخفاق عام في التنافسية بنسبة 60% . وظهر ان اهم تلك الاخفاقات كامنة في معالجة الفساد والاستقرار السياسي والامني وولاء قوة العمل ووضوح الانظمة الضريبية اضافة الى فشل باقي المرتكزات.

ان المحاولات الحالية للحكومة لا زالت متواضعة وهي جذب الاستثمارات الاجنبية من خلال قانون الاستثمار وبعض الاتفاقات الاستثمارية الواعدة. الا ان ما ينبغي فعله يرتكز على اصلاح هيكل القرار الاستراتيجي المفضي الى استقرار سياسي وامني طويل الاجل وراسخ كشرط للإصلاح الاقتصادي الذي يؤطر استراتيجية للقدرة التنافسية تتخذ الملامح التالية:

المرحلة الابتدائية : بناء فريق عمل التنافسية وبناء المرصد الوطني للتنافسية.

مرحلة الانطلاق:

1) نشر مفهوم التنافسية الشامل بين مختلف شرائح قطاع الاعمال وبناء القدرة الوطنية.

2) قياس مؤشرات تنافسية الاقصاد العراقي ومقارنتها مع  مجموعة الدول الاخرى. 

3) المساعدة على تعزيز القدرة التنافسية لقطاع الاعمال العراقي عبر وضع منهجية تحليل السلسلة        التكنولوجية بالاعتماد على البحث الميداني والبحث المكتبي.

4) صياغة السياسات القطاعية بناءا على التحليل المذكور ودفعها لمتخذي القرار بهدف تعزيز ودعم      آلية جذب الاستثمارات.

يهدف البحث الحالي الى استكشاف محددات السلوك الريادي من منظور الهوية الاجتماعية، منطلقاً من افكار نموذج (Tyler & Blader, 2003) التي تركز على دراسة دور الهوية الشخصية الايجابية ودور الهوية الاجتماعية الايجابية في تحفيز العاملين على ممارسة السلوك المرغوب الذي يخدم المنظمة. وبناءً على هذه الافكار والاطر النظرية السابقة تم بناء نموذج يوضح العلاقة بين الاحتكام للمكانة (الاحترام الداخلي المدرك والمكانة الخارجية المدركة) والسلوك الريادي. يشمل المضمون الفكري لهذا النموذج على ثلاث فرضيات، الفرضية الاولى والثانية تخص العلاقة بين الاحتكام للمكانة والسلوك الريادي، اما الفرضية الثالثة فتهتم باختبار دور متغير المكانة الخارجية المدركة كمتغير معدل بين الاحترام الداخلي المدرك والسلوك الريادي. وجمعت البيانات من عينة من ثلاث كليات من جامعة القادسية شملت (152) فرد. وبعد استخراج النتائج تم صياغة عدد من الاستنتاجات والتوصيات الهادفة.
Investment Perspective According to Behavioral Finance Science
Authors: Al-Anizi Sa’ad
Published: January 2019

The first thing that comes to mind is the highly important question of whether there were some effects of human behavior and its fluctuations on the theories of the efficient market and the contemporary investment portfolio. According to what has been said by the proponents of these two theories; when the optimal return is realized, the efficiency of the market is achieved in terms of perfect information on prices and risk that supposed to be predetermined in a rational way.

he other question that imposed here is “at what time people should be rational in their investments in the security markets ?”. This means that investors are rational for their efforts devoted to utility maximization, which are perceived as a result of investing their wealth in the best possible manner.

Then, can those two questions be achieved in practice? Many ontological aspects are influenced in their relations by emotions and feelings more than by money as a financial resource . Investors may take irrational financial decisions because of the dominance of those emotions and feelings compared with what investors do toward other actions in their public and special daily life.

Understanding investors financial awareness without taking into account the human action is considered as an outstanding problem which can be assimilated as an attempt to sail with compass, but without guided maps. The importance and necessity of human psychological factor are arise when we are talking about investing common stocks in the security market. Then, this means that issues directing investment decisions of individuals in financial assets whether they were stocks or bonds, can be only interpreted with referring to principles of human behavior.

Absolutely there is no exaggeration if we said that the market in general be advanced, lagged behind , prospected , and crept when making collective  decisions in buying securities through viewing  psychological factors which capture individuals behaviors after information being collected and analyzed. The validity of an efficient market theory has been widely accepted by its proponents for a long time lasting almost a century so that any research on  the psychological aspects of a security market encountered by objection till a close time of ten years .

Published: January 2019

رغم كل الامكانيات التي يمتلكها العراق لأنتاج الاسماك إلا انه هناك تدني في مستوى الانتاج وفي معدل استهلاك الفرد يعود إلى جملة اسباب منها ضعف حجم الاستثمارات، توقف الدعم الحكومي، انخفاض كبير في كميات المياه، ارتفاع نسبة الملوحة ونسبة التلوث في المياه، استخدام وسائل واساليب صيد بدائية، ضعف القوانين والتشريعات، سياسة اغراق الاسواق بالمنتجات المستوردة.

رغم كل ذلك اظهر البحث ان هناك فرص استثمارية كبيرة جداً في هذا القطاع من خلال حجم السوق والقدرة الاستيعابية له ونمو دخل الفرد ومستواه الثقافي عزز ذلك دراسة الجدوى التي اقيمت واعطت مؤشراً جيداً ومشجعاً على الاستثمار.
آليات حوكمة الشركات التي تؤثر في اتخاذ المدقق الداخلي للقرار الاخلاقي
Authors: الدوغجي علي حسين
Published: January 2019

اصبح لمجالس الادارة في الشركات دوراً حاسماً في تعزيز الحوكمة الفاعلة، كونها تتحمل المسؤولية النهائية عن نظم الرقابة الداخلية في شركاتها، ويلعب التدقيق الداخلي دوراً اساسياً في مساعدة تلك المجالس على القيام بمهمات الحوكمة. ولهذا يبذل مجمع المدققين الداخليين الامريكي جهداً كبيراً في توجيه اعضاءه ليكونوا متخصصين في اصول حوكمة الشركات وتحسين وتقوية اخلاقيات العمل وسلامة المنظمة.

لذا فإن البحث يتناول مدى تفاعل المدقق الداخلي مع بعض المعضلات الاخلاقية التي تشكل تحدي كبير لمبادئه، وخصوصاً عندما يواجه ضغوطات الادارة العليا عندما تطلب منه ان يتأقلم مع الوضع وان لا يسبب أي مشكلات.

وقد توصل البحث الى بعض الاستنتاجات اهمها:

ان المدققين الداخليين كمجموعة يظهرون حساسية عالية الى حد معقول للقضايا الاخلاقية من خلال تقييم موقفهم نحو عدم التصرف عندما يواجهون المعضلات الاخلاقية.

ان وجود لجنة تدقيق فعالة ونظام ضبط داخلي وتنظيمي قوي وسلامة وصحة تصرفات الادارة، يؤدي الى مساعدة المدققين للتصرف بشكل اخلاقي عند مواجهة معضلة.

البحث يمثل صورة مبسطة لحقيقة المعضلات الاخلاقية التي تواجه المدقق الداخلي وان النتائج مفيدة وتوفر فرص كثيرة لأبحاث في المستقبل في هذا المجال.

Published: January 2019

Background: Vitamin and mineral supplementation is common practice in both human and animal health, But indiscriminate, overdose and long term used may cause toxicity. The research work was designed to evaluate the effect of iron (Fe) &vitamin B12 (Vit-B12) on body weight, hematological parameters: Total Erythrocyte Count (TEC), Hemoglobin (Hb) and Total Leukocyte Count (TLC), and biochemical parameters: serum creatinine (SC), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in mice.

Methods: One-month old 20 female Swiss Albino mice (Rattus norvegicus) having 19.52±0.54 g body weight were divided into four equal groups (n=5). After acclimatization, the mice of group A was treated with Fe@ 0.2 mg/kg body weight (bwt) in pellet, group B was treated with Vit-B12 @ 5 mg/kg bwt, group C was treated with combination of Fe and Vit-B12 and group D was fed with standard pellet and was considered as control.

Results: The result showed significant (P<0.05) increase in body weight of treatment groups compared to the control group. The values of TEC, Hb and TLC in the treated groups were increased significantly (P<0.05). ALT, AST and SC values were decreased significantly (P<0.05) in the treated groups compared to the control group.

Conclusions: It is concluded that administration of Fe and Vit-B12 significantly (P<0.05) increased body weight and hematological (TEC, Hb, and TLC) parameters however biochemical parameters (ALT and AST) were decreased significantly (P<0.05). In addition, combination of Fe&Vit-B12 showed better effects compared to their single uses.
