Embracing the ICT revolution to promote economic growth in developing countries: policy challenges

У даній роботі аналізується вплив використання інструментів ІКТ (інформаційних і комунікаційних технологій) на стимулювання економічного зростання. Зокрема, у статті досліджуються питання пов'язані з ризиком таргетування сектору ІКТ, як стратегічно важливого, і можливими економічними наслідками у разі проникнення сектора ІКТ в усі сфери господарської діяльності. У роботі стверджується, що проникнення (впровадження) сектору ІКТ в усі галузі народного господарства принесуть безсумнівно більший економічний ефект, ніж його цільове використання у поточній перспективі. Наведено економічну модель, що враховує ефективність використання ІКТ у стратегічних планах держави. В роботі пропонується створити всередині країни ринки для розвитку ІКТ технологій і прослідкувати за дотриманням добросовісної конкуренції в цьому сегменті ринку. На основі створеного ринку ІКТ пропонується вдосконалювати бізнес середовище і управління, через стимулювання електронної комерції та електронного управління. Очікуваними витратами проекту вважаються затрати на фінансування реструктуризації телекомунікаційного сектору і підвищення якості послуг в сфері ІКТ. Запропонований механізм вдосконалення послуг ІКТ хоча й передбачає певні затрати, але очікуваний економічний ефект від вдосконалення сервісної складової в структурі валового доданого продукту набагато вищий. Використання ІКТ пов'язане з економією транзакційних витрат і зменшенням ризику недосконалої конкуренції. Зокрема в роботі приводяться приклади мінімізації транзакційних витрат у зв'язку із застосуванням електронної комерції в США. Електронна комерція майже повністю виключає можливість узурпації ринку окремими покупцями чи продавцями. Фактор ІКТ розглядається як один з визначальних у формуванні ефективності й конкурентоздатності окремих фірм. Розроблена економічна модель дозволяє оцінити ефект ІКТ та економічне зростання як окремих регіонів, так і країни в цілому. Представлена модель враховує динамічний характер технологічних змін у виробничому середовищі, а також можливості цілеспрямованого й найбільш швидкого використання технологічних досягнень завдяки ІКТ. Особлива увага в роботі приділена аналізу економічних проблем пов'язаних з розробкою та керуванням програмою ІКТ з метою її найбільш швидкого поширення в економічній системі. В завершення роботи приводиться декілька прикладних Internet можливостей, які можуть бути ефективно використані для стимулювання економічного росту на мікроекономічному й регіональному рівнях.

The paper discusses the risk of targeting the ICT-producing sector as a strategic industry and analyzes the trade-off due to neglecting efforts to foster the diffusion of ICT throughout the economy. The paper concludes that promoting ICT diffusion throughout the economy should is more crucial than targeting the ICT-producing sector for a country to reap the benefits of ICT for economic growth. The paper then introduces economic frameworks which underlie an effective ICT agenda. При цитировании документа, используйте ссылку http://essuir.sumdu.edu.ua/handle/123456789/878

Information Technology and The World Growth Resurgence

This paper analyzes the impact of investment in information technology (IT) on the recent resurgence of world economic growth. We describe the growth of the world economy, seven regions, and fourteen major economies during the period 1989-2004. We allocate the growth of world output between input growth and productivity and find, surprisingly, that input growth greatly predominates! Moreover, differences in per capita output levels are explained by differences in per capita input, rather than variations in productivity. The contributions of IT investment have increased in all regions, but especially in industrialized economies and Developing Asia.growth, investment, productivity, information technology

Information technology and the world economy

The purpose of this paper is to analyze the impact of investment in information technology (IT) equipment and software on the recent resurgence in world economic growth. The crucial role of IT investment in the growth of the U.S. economy has been thoroughly documented and widely discussed. Jorgenson (2001) has shown that the remarkable behavior of IT prices is the key to understanding the resurgence of American economic growth. This behavior can be traced to developments in semiconductor technology that are widely understood by technologists and economists.

Backwardness Advantage and Economic Growth in the Information Age: A Cross-Country Empirical Study

This paper seeks to gain insights into whether developing countries benefit more from the backwardness advantage for economic growth in the Information Age. The paper examines this concern through three complementary approaches. First, it derives theoretical grounds from the existing economic models to support the hypothesis that the internet, inter alia, enables developing countries to reap greater growth gains from technology acquisition and catch-up. Second, the paper uses descriptive evidence to show that the growth landscape has indeed shifted decisively in favor of developing countries in the Internet Age in comparison to the pre-internet period. Third, using rigorous econometric techniques with data of 163 countries over a 20-year period, 1996-2016, the paper evidences that developing countries on average reap significantly greater growth gains from internet adoption in comparison to the average advanced country. The paper discusses policy implications from the paper’s findings

Statistical evaluation of the geochemical data for prospecting polymetallic mineralization in the Suoi Thau – Sang Than region, Northeast Vietnam

In Northeast Vietnam, Suoi Thau-Sang Than is considered as a high potential area of polymetallic deposits. 1,720 geochemical samples were used to investigate polymetallic mineralization; thereby polymetallic ore occurrences in this study region were discovered and the statistical and multivariate analysis helps to define geochemical anomalies in some northeastern regions, namely Suoi Thau, Sang Than, and Ban Kep. The statistical method and cluster analysis of geochemical data indicate that the Cu, Pb, and Zn elements are good indicators, and most of them comply with the lognormal or gamma distribution. Based on the third-order threshold, the geochemical anomalies of the content of the Cu, Pb, and Zn elements reflect the concentration of copper forming ore bodies in the mineralized zone, and clearly show the concentration in three distinct zones. The trend surface analysis which was employed to determine spatial variations and relationships among these good indicator elements and anomalous areas revealed relative changes in the content of the indicator elements, and they can be considered as regular. Moreover, the goodness of fit obtained trend functions of Pb and Zn, and Cu elements is a third-degree trend surface model. These results indicate that the models can be useful in studying geochemical anomalies and analyzing the tendency of the concentration of indicator elements in the Suoi Thau-Sang Than region. Additionally, it is suggested that the statistical analysis shows a remarkable potential to use the bottom river sediments in the region to investigate polymetallic mineralization. Moreover, geochemical data can help to evaluate geochemical anomalies of the pathfinder elements and potential mineral mapping of the Suoi Thau-Sang Than region in Northeast Vietnam

El trauma de los niños vietnamitas que viven en familias incompletas

Children living in incomplete families have to suffer from more hardships than others including psychological trauma that could never be cured without safe approaches. In this paper, we used the Children Behavior Checklist (CBCL test) by Achenbach to initially filter the incidence of children in incomplete families with psychological trauma, the extent of childhood trauma, and the signs of trauma. Moreover, the Self-esteem scale of Toulouse was also utilized to investigate children's self-esteem and determine the impact of psychological trauma on the self-assessment of children. Based on these tools, the research conducted a correlation analysis of psychological trauma of children in incomplete families through indicators of awareness of, emotions with, and behaviors towards family and social life (self-evaluated by children). The results showed that there are differences in psychological trauma of children in terms of awareness, emotions, and behaviors. The differences allow for a better definition of children's causes, influences, and degrees of psychological trauma. This is the basis for proposing timely filtering solutions and effective psychological support measures for these children. Keywords: correlation analysis; signs of psychological trauma; children; incomplete family; Vietnam.Los niños que viven en familias incompletas tienen que sufrir más dificultades que otros, incluido el trauma psicológico que nunca podría curarse sin enfoques seguros. En este artículo, se utiliza la Lista de Verificación de Comportamiento Infantil (prueba CBCL) de Achenbach para filtrar inicialmente la incidencia de niños en familias incompletas con trauma psicológico, el alcance del trauma infantil y los signos de trauma. Además, la escala de autoestima de Toulouse también se utilizó para investigar la autoestima de los niños y determinar el impacto del trauma psicológico en la autoevaluación de los niños. Con base en estas herramientas, la investigación realizó un análisis de correlación del trauma psicológico de los niños en familias incompletas a través de indicadores de conciencia, emociones y comportamientos hacia la vida familiar y social (autoevaluados por los niños). Los resultados mostraron que existen diferencias en el trauma psicológico de los niños en términos de conciencia, emociones y comportamientos. Las diferencias permiten una mejor definición de las causas, influencias y grados de trauma psicológico de los niños. Esta es la base para proponer soluciones de filtrado oportunas y medidas de apoyo psicológico eficaces para estos niños.

Flocculation of Reactive Blue 19 (RB19) using Alum and the Effects of Catalysts Addition

There are a variety of primary coagulants which can be used in a water treatment plant. One of the earliest, and still the most extensively used, is aluminum sulfate, also known as alum. Aluminum Sulfate (Alum) is one of the most commonly used flocculent in waste water treatment processes. Effectiveness of Alum in flocculation process is determined by many factors such as the effluents pH, flocculent dose as well as the use of catalyst to improve efficiency rate of flocculation. Hence special attention to these factors especially the use of catalyst has been brought about by this study. Experiments were carried out using Reactive Blue 19 Dye as the contaminant of waste water and two catalysts namely Calcium Hydroxide (CaOH2) and Poly Aluminum Chloride (PACl) were evaluated. The results obtained proved that indeed after addition of catalysts, removal efficiency rates of Alum can be increased up to 25% using Calcium Hydroxide and up to 35% using Poly Aluminum Chloride compared to Alum alone. The optimum conditions for this study were at pH 5.5 ~7.5, 300 mg/L of Alum 30seconds of rapid mixing time with 300 rpm , 30rpm of mixing rate for 5 minutes and 30 minutes of settling time. Moreover, Alum showed the highest performance under these conditions and using 50 mg/L PACl as catalyst with 98.52% of COD reduction and 90.60% of color reduction. In conclusion, Alum with the support of PACl as catalyst is an effective coagulant, which can reduce the level of COD and Dye Color in Reactive Blue 19 contaminated wastewater

PATHOGENICITY OF EIMERIA SPECIES ISOLATED FROM CHICKEN IN THUA THIEN HUE PROVINCE

Abstract: The present study clarifies the effect of locally isolated Eimeria species on chickens in central Vietnam. Oocysts of Eimeria species were isolated from feces suspected to be infected with coccidiosis in 3 farms in Huong Thuy district, Thua Thien Hue province. A total of 54 2-week-old chickens were randomly allocated to 2 groups: 3 replicates containing 9 chickens in each replicate. The chicken in group 1 were orally inoculated with 2×104 isolated oocysts of Eimeria species, while the chickens in group 2 were inoculated with PBS as a control. Growth performance, oocyst output, gross lesions, and histopathological lesions were measured at 5, 10 and 28 days after infection. The chicks in group 1 showed general signs of ruffled feathers, anorexia, huddling together with diarrhea and/or bloody dropping from 4–7 days post-infection. Feed intake, growth performance and body weight in group 1 were lower than those of the control chicks. The oocyst was detected in the feces of chicks in group 1 from 6–14 days post-infection, among them, the number of oocysts reach the peak at 8 days post-infection. At day 5 post-infection, the most damaged part of the intestine is the ceca with a large amount of blood in the ceca content. The histopathological lesions were detected clearly by HE staining at day 5 and 10 post-infection. In conclusion, the locally isolated oocysts of Eimeria species have high virulence to the chickens. The present study provides useful information related to the pathogenicity of Eimeria species which may contribute to coccidiosis diagnosis and treatment in poultry production.Keywords: Eimeria, coccidiosis, infection, central Vietna
