2217 Vehicular Emission Estimation of Islamabad by Using Copert-5 Model

Authors: Muhammad Jahanzaib, Muhammad Z. A. Khan, Junaid Khayyam

Abstract:

Islamabad is the capital of Pakistan with the population of 1.365 million people and with a vehicular fleet size of 0.75 million. The vehicular fleet size is growing annually by the rate of 11%. Vehicular emissions are major source of Black carbon (BC). In developing countries like Pakistan, most of the vehicles consume conventional fuels like Petrol, Diesel, and CNG. These fuels are the major emitters of pollutants like CO, CO2, NOx, CH4, VOCs, and particulate matter (PM10). Carbon dioxide and methane are the leading contributor to the global warming with a global share of 9-26% and 4-9% respectively. NOx is the precursor of nitrates which ultimately form aerosols that are noxious to human health. In this study, COPERT (Computer program to Calculate Emissions from Road Transport) was used for vehicular emission estimation in Islamabad. COPERT is a windows based program which is developed for the calculation of emissions from the road transport sector. The emissions were calculated for the year of 2016 include pollutants like CO, NOx, VOC, and PM and energy consumption. The different variable was input to the model for emission estimation including meteorological parameters, average vehicular trip length and respective time duration, fleet configuration, activity data, degradation factor, and fuel effect. The estimated emissions for CO, CH4, CO2, NOx, and PM10 were found to be 9814.2, 44.9, 279196.7, 3744.2 and 304.5 tons respectively.

2216 Inclusive Business and Its Contribution to Farmers Wellbeing in Arsi Ethiopia: Empirical Evidence

Authors: Senait G. Worku, Ellen Mangnus

Abstract:

Inclusive business models which integrates low-income people with companies value chain in a commercially viable way has gained momentum for the perceived potential to contribute to poverty alleviation and food security in developing countries. This article investigates the impact of Community Revenue Enhancement through Technology Extension (CREATE) project of Heineken brewery on smallholder farmers’ wellbeing in Arsi zone Oromia regional state of Ethiopia. CREATE is a Public-Private Partnership (PPP) between Ministry of Foreign Affairs of the Netherlands and Heineken N.V. which source malt barely from smallholder farmers in three zones of Oromia. The study assessed the impact of CREATE on malt barley productivity, food security and new asset purchase in Arsi zone by comparing households that participate in the project with non-participating households using propensity score matching method. The finding indicated that households that participated in the CREATE project had higher malt barley productivity and purchased more new assets than non-participating households. However, there is no significant difference on food security status of participating and non-participating households indicating that the project has a profound impact on asset accumulation than on food security improvement.

2215 Fault Detection and Isolation in Sensors and Actuators of Wind Turbines

Authors: Shahrokh Barati, Reza Ramezani

Abstract:

Due to the countries growing attention to the renewable energy producing, the demand for energy from renewable energy has gone up among the renewable energy sources; wind energy is the fastest growth in recent years. In this regard, in order to increase the availability of wind turbines, using of Fault Detection and Isolation (FDI) system is necessary. Wind turbines include of various faults such as sensors fault, actuator faults, network connection fault, mechanical faults and faults in the generator subsystem. Although, sensors and actuators have a large number of faults in wind turbine but have discussed fewer in the literature. Therefore, in this work, we focus our attention to design a sensor and actuator fault detection and isolation algorithm and Fault-tolerant control systems (FTCS) for Wind Turbine. The aim of this research is to propose a comprehensive fault detection and isolation system for sensors and actuators of wind turbine based on data-driven approaches. To achieve this goal, the features of measurable signals in real wind turbine extract in any condition. The next step is the feature selection among the extract in any condition. The next step is the feature selection among the extracted features. Features are selected that led to maximum separation networks that implemented in parallel and results of classifiers fused together. In order to maximize the reliability of decision on fault, the property of fault repeatability is used.

Authors: Raihan Zahirah Mauludy Ridwan, Frisca Devi Choirina

Abstract:

Indonesia with its former presidents has enhanced the bilateral cooperation also multilateral cooperation in terms of economy but the result was not significant towards eradicating poverty, unemployment, income inequality, and economic growth. To eradicate these problems, President Joko Widodo through his several points of Nawacita wants to boost Indonesia’s economic relationship and cooperation which manifested in “Economic Diplomacy” as one of Indonesia’s foreign policy priority and he pitches it in international forums. The economic diplomacy does not only attracts prospective countries but also attracts the foreign businessman and investors. The economic diplomacy includes four sectors which are vital for economic growth, one of them is investment. This paper would like to answer how economic diplomacy can have significant impact towards social welfare, equity and economic growth especially in Indonesia. The purpose of this paper is to explore the role of economic diplomacy and its impact toward Indonesia’s welfare, equity, and economic growth. This paper uses the theory of economic diplomacy to link the current international political economic sphere and the impact of economic diplomacy for Indonesia through case study method. The paper affirms that economic diplomacy in investment sector does have significant impact, especially in the development of infrastructures, foreign direct investment in several sectors, and food security.

2213 Bridging the Gap through New Media Technology Acceptance: Exploring Chinese Family Business Culture

Authors: Farzana Sharmin, Mohammad Tipu Sultan

Abstract:

Emerging new media technology such as social media and social networking sites have changed the family business dynamics in Eastern Asia. The family business trends in China has been developed at an exponential rate towards technology. In the last two decades, many of this family business has succeeded in becoming major players in the Chinese and world economy. But there are a very few availabilities of literature on Chinese context regarding social media acceptance in terms of the family business. Therefore, this study has tried to cover the gap between culture and new media technology to understand the attitude of Chinese young entrepreneurs’ towards the family business. This paper focused on two cultural dimensions (collectivism, long-term orientation), which are adopted from Greet Hofstede’s. Additionally perceived usefulness and ease of use adopted from the Technology Acceptance Model (TAM) to explore the actual behavior of technology acceptance for the family business. A quantitative survey method (n=275) used to collect data Chinese family business owners' in Shanghai. The inferential statistical analysis was applied to extract trait factors, and verification of the model, respectively. The research results found that using social media for family business promotion has highly influenced by cultural values (collectivism and long-term orientation). The theoretical contribution of this research may also assist policymakers and practitioners of other developing countries to advertise and promote the family business through social media.

2212 Immigrant Status and System Justification and Condemnation

Authors: Nancy Bartekian, Kaelan Vazquez, Christine Reyna

Abstract:

Immigrants coming into the United States of America may justify the American system (political, economic, healthcare, criminal justice) and see it as functional. This may be explained because they may come from countries that are even more unstable than the U.S. and/or come here to benefit from the promise of the “American dream” -a narrative that they might be more likely to believe in if they were willing to undergo the costly and sometimes dangerous process to immigrate. Conversely, native-born Americans, as well as immigrants who may have lived in America for a longer period of time, would have more experiences with the various broken systems in America that are dysfunctional, fail to provide adequate services equitably, and/or are steeped in systemic racism and other biases that disadvantage lower-status groups. Thus, our research expects that system justification would decrease, and condemnation would increase with more time spent in the U.S. for immigrant groups. We predict that a) those not born in the U.S. will be more likely to justify the system, b) they will also be less likely to condemn the system, and c) the longer an immigrant has been in the U.S. the less likely they will to justify, and more they will to condemn the system. We will use a mixed-model multivariate analysis of covariance (MANCOVA) and control for race, income, and education. We will also run linear regression models to test if there is a relationship between the length of time in the United States and a decrease in system justification, and length of time and an increase in system condemnation for those not born in the U.S. We will also conduct exploratory analyses to see if the predicted patterns are more likely within certain systems over other systems (political, economic, healthcare, criminal justice).

Authors: Sanober Khanum, Barerah Siddiqui, Asim Qidwai

Abstract:

Objective: To determine the risk factors and frequency of depressive trends in children and adolescents suffering from Beta-Thalassemia. Background: Thalassemia is a chronic disease affecting 10,000 people in 60 countries. Many studies show that prolonged medical conditions cause depression. Due to the invasive procedures and suffering, Beta-Thalassemia cause great psychological distress to both children and their caregivers. The study shows 14-24% prevalence of psychiatric problems in Thalassemic patients. Method: Sample consisted of 195 registered patients of A.M.T.F (Female=95 and Male=100). Based on age range the sample was divided into two groups, Group A = children (4-9 years) and Group B = adolescent (10-16 years). A detailed interview with a self-made screening measure was administered on parents to find out the level of depression in patients. Statistics: Chi-square and t-test was applied in order to analyze the data. Results show high prevalence of depression, depression n= 131(66.83%), no depression n=65(33.16%). Analyses reflect that age influences the level of depression Adolescent (71.05%) and Children (64.16%). The analysis also shows a difference in level of depression between both genders. (t=2.975, p < .05). Conclusion: There is a high possibility of developing depressive trend in children affected with Beta Thalassemia; especially females. Therefore, there is a dire need for psychological screening and appropriate treatment in order to improve physical; as well as mental health.

2210 Iodine-Doped Carbon Dots as a Catalyst for Water Remediation Application

Authors: Anurag Kumar Pandey, Tapan Kumar Nath, Santanu Dhara

Abstract:

Polluted water by industrial effluents or dyes has become a major global concern, particularly in developing countries. Such environmental contaminants constitute a serious threat to biodiversity, ecosystems, and human health worldwide; thus, their treatment is critical. The usage of nanoparticles has been discovered to be a potential water treatment method with high efficiency, cheap manufacturing costs, and green synthesis. Carbon dots have attracted the interest of researchers due to their unique properties, such as high water solubility, ease of production, great electron-donating ability, and low toxicity. In this context, we synthesized iodine-doped clove buds-derived carbon dots (I-CCDs) for the Fenton-like degradation of environmental contaminants in water (such as methylene blue (MB) and rhodamine-B (Rh-B) dye). The formation of I-CCDs has been confirmed using various spectroscopy techniques. I-CCDs have demonstrated remarkable optical, cytocompatibility, and antibacterial capabilities. The C-dots that were synthesized were found to be an effective catalyst for the reduction of MB and Rh-B utilizing NaBH4 as a reducing agent. UV-visible spectroscopy was used to construct a detailed pathway for dye reduction step by step. As-prepared I-CCDs have the potential to be a promising solution for wastewater purification and treatment systems.

2209 Modelling Phytoremediation Rates of Aquatic Macrophytes in Aquaculture Effluent

Authors: E. A. Kiridi, A. O. Ogunlela

Abstract:

Pollutants from aquacultural practices constitute environmental problems and phytoremediation could offer cheaper environmentally sustainable alternative since equipment using advanced treatment for fish tank effluent is expensive to import, install, operate and maintain, especially in developing countries. The main objective of this research was, therefore, to develop a mathematical model for phytoremediation by aquatic plants in aquaculture wastewater. Other objectives were to evaluate the retention times on phytoremediation rates using the model and to measure the nutrient level of the aquaculture effluent and phytoremediation rates of three aquatic macrophytes, namely; water hyacinth (Eichornia crassippes), water lettuce (Pistial stratoites) and morning glory (Ipomea asarifolia). A completely randomized experimental design was used in the study. Approximately 100 g of each macrophyte were introduced into the hydroponic units and phytoremediation indices monitored at 8 different intervals from the first to the 28th day. The water quality parameters measured were pH and electrical conductivity (EC). Others were concentration of ammonium–nitrogen (NH₄⁺ -N), nitrite- nitrogen (NO₂⁻ -N), nitrate- nitrogen (NO₃⁻ -N), phosphate –phosphorus (PO₄³⁻ -P), and biomass value. The biomass produced by water hyacinth was 438.2 g, 600.7 g, 688.2 g and 725.7 g at four 7–day intervals. The corresponding values for water lettuce were 361.2 g, 498.7 g, 561.2 g and 623.7 g and for morning glory were 417.0 g, 567.0 g, 642.0 g and 679.5g. Coefficient of determination was greater than 80% for EC, TDS, NO₂⁻ -N, NO₃⁻ -N and 70% for NH₄⁺ -N using any of the macrophytes and the predicted values were within the 95% confidence interval of measured values. Therefore, the model is valuable in the design and operation of phytoremediation systems for aquaculture effluent.

2208 Policies and Practice of Refugee Education from Malaysian Perspective: Preliminary Findings

Authors: A. H. A. Hamid, N. A. Zainuddin, M. Y. M. Nor

Abstract:

Millions of child refugees leave their countries in the hope of better and safer lives particularly in the aspect of education. However, the education access for the child refugees is strongly depending on the policies made by the federal and local governments. Malaysia, in particular, is a country which does not have a specific educational policy that is inclusive of child refugees. Hence, this study explores the feasibility of possible educational policy that specifically caters the needs of child refugees in Malaysia. These are preliminary findings of a case study which involved thirty-five postgraduate students in a local university who undertook Educational Policy coursework and five teachers in a refugee community centre in Kuala Lumpur, Malaysia. Interviews were recorded, transcribed and thematically analysed in relation to issues highlighted in the refugee education literature. The findings showed that most of the informants felt there is an urgent need of a systematic intervention put in place by the local government to cater to the needs of equal education access to the child refugees. A further large scale study is needed in the near future by integrating different perspectives of relevant stakeholders for an effective, efficient and sustainable policy formulation and implementation related to child refugees in Malaysia. The findings may be of interests to the educators, the ministry of education, state education office, district education office, teachers, parents and surrounding communities for their awareness about the needs of refugee education and the feasibility of educational policy for child refugees in the country.

2207 Students With Special Educational Needs in Regular Classrooms and their Peer Effects on Learning Achievement

Authors: José María Renteria, Vania Salas

Abstract:

This study explores the impact of inclusive education on the educational outcomes of students without Special Educational Needs (non-SEN) in Peru, utilizing official Ministry of Education data and implementing cross-sectional regression analyses. Inclusive education is a complex issue that, without appropriate adaptations and comprehensive understanding, can present substantial challenges to the educational community. While prior research from developed nations offers diverse perspectives on the effects of inclusive education on non-SEN students, limited evidence exists regarding its impact in developing countries. Our study addresses this gap by examining inclusive education in Peru and its effects on non-SEN students, thereby contributing to the existing literature. the findings reveal that, on average, the presence of SEN students in regular classrooms does not significantly affect their non-SEN counterparts. However, we uncover heterogeneous effects contingent on the specific type of SEN and students’ academic placement. These results emphasize the importance of targeted resources, specialized teachers, and parental involvement in facilitating successful inclusive education, particularly for specific SEN types and students positioned at the lower end of the academic achievement spectrum. In summary, this study underscores the need for tailored strategies and additional resources to foster the success of inclusive education and calls for further research in this field to expand our understanding and enhance educational policy.

2206 Sexual Behaviour and Psychological Well-Being of a Group of African Adolescent Males in Alice, Eastern Cape

Authors: Jabulani Gilford Kheswa, Thembelihle Lobi

Abstract:

From a cultural perspective, expression of hegemonic masculinity in South Africa continues to escalate among adolescent males who grow up in communities lacking in role models and recreational facilities. However, when the schools are constructive, and peer influence is positive, adolescent male can potentially express character strengths and lead a meaningful life. Drawing from Bronfenbrenner’s Ecological Model and Keyes and Ryff’s six dimensions of psychological well-being and mental health, such youth may exemplify positive self-esteem, problem- focused coping strategies, condom self-efficacy, good leadership skills, enhanced motivation and a positive emotional state, which buffer against risky sexual behaviors. This paper was aimed at investigating the relationships between adolescent males’ sexual behavior and psychological well-being. This study employed a quantitative research to collect data from 54 Xhosa-speaking adolescent males from one school high school in Fort Beaufort, Eastern Cape, South Africa. These learners were from grade nine, ten and eleven with their ages ranging from 14 to 20. Prior the research commenced, the school principal and caregivers of the learners who participated in the study, gave their informed consent. Self- administered closed-ended questionnaire with Section A (that is, biographical information) and Section B with each question rated on the 5–point Likert scale was used. The advantages of questionnaires include a high response rate as they require less time and offer anonymity because participants’ names are not identified. The SPSS version 18 was used for statistical data analysis. The mean age was 16.83 with a standard deviation of 1.611. 44.4% of the participants were from grade 9, 33.3% from grade 10 and 22.2% from grade 11. The Chronbach alpha of 0.79 was yielded, with respect to self- esteem of adolescent males. In this study, 76.9% reported to attend church services whilst 23% indicated not to attend church services. A further 96.2% of adolescent males indicated to have good relations with guardians while only 3.8% had poorer relations. A large proportion of adolescent males (72.9%) indicated to high-quality friendship as opposed to 27.1% who reported being receiving negative guidance from peers. Other findings revealed that 81.1% of the participants’ parents do not drink alcohol, and they cope at school as 79.6% reported protective factors as attributable towards non-engagement to risky sexual practices. As a result, 81.4% of participants reported not to participate in criminal activities although 85% of the participants indicated that in their school there are drugs. It could be speculated from this study that adolescent males whose caregivers are authoritative, find purpose in life and are most likely to be socially and academically competent. This paper leads to further research interest into mental health, coping strategies and sexual decision-making skills of the youth in South Africa.

2205 Groundwater Contamination Assessment and Mitigation Strategies for Water Resource Sustainability: A Concise Review

Authors: Khawar Naeem, Adel Elomri, Adel Zghibi

Abstract:

Contamination leakage from municipal solid waste (MSW) landfills is a serious environmental challenge that poses a threat to interconnected ecosystems. It not only contaminates the soil of the saturated zone, but it also percolates down the earth and contaminates the groundwater (GW). In this concise literature review, an effort is made to understand the environmental hazards posed by this contamination to the soil and groundwater, the type of contamination, and possible solutions proposed in the literature. In the study’s second phase, the MSW management practices are explored as the landfill site dump rate and type of MSW into the landfill site directly depend on the MSW management strategies. Case studies from multiple developed and underdeveloped countries are presented, and the complex MSW management system is investigated from an operational perspective to minimize the contamination of GW. One of the significant tools used in the literature was found to be Systems Dynamic Modeling (SDM), which is a simulation-based approach to study the stakeholder’s approach. By employing the SDM approach, the risk of GW contamination can be reduced by devising effective MSW management policies, ultimately resulting in water resource sustainability and regional sustainable development.

2203 The Concept of Development: A Normative Restructured Model in the Light of Indian Political Thought and Classical Liberalism

Authors: Sarthak S. Salunke

Abstract:

Development, as a notion, is seen in perspective of western philosophical conceptions, and the western developed nations have become a yardstick for setting up development goals for developing and underdeveloped nations around the world. This blanket term of development becomes superficial and materialistic in context of the vast geopolitical, territorial, cultural and behavioral diversities existing in countries of the Africa and the Asia, and tends to undermine the atomistic aspect of development. Indian political theories, which are often seen as religious philosophies, have inherent structure of development of human being as an individual and as a part of the society, and, in result, development of the State. These theories, primarily individualistic in nature, have a combination of altruism and rationalism which guides human beings towards constructing a collectively developed and morally sustainable society. This research focuses on the application of this Indian thought in combination of classical liberal thought to tackle the issues of development in diverse societies. The proposed restructured model of development is based on molecular individualism, instead of atomic individual approach of liberalists, which lets development modelers to target meaningful clusters for designating goals for development based on the particular needs based on geopolitical, cultural and ethical requirements, and making it meaningful in conjunction with global development to establish a harmony between western and eastern worlds.

2202 Quantitative Analysis of the Functional Characteristics of Urban Complexes Based on Station-City Integration: Fifteen Case Studies of European, North American, and East Asian Railway Stations

Authors: Dai Yizheng, Chen-Yang Zhang

Abstract:

As station-city integration has been widely accepted as a strategy for mixed-use development, a quantitative analysis of the functional characteristics of urban complexes based on station-city integration is urgently needed. Taking 15 railway stations in European, North American, and East Asian cities as the research objects, this study analyzes their functional proportion, functional positioning, and functional correlation with respect to four categories of functional facilities for both railway passenger flow and subway passenger flow. We found that (1) the functional proportion of urban complexes was mainly concentrated in three models: complementary, dominant, and equilibrium. (2) The mathematical model affected by the functional proportion was created to evaluate the functional positioning of an urban complex at three scales: station area, city, and region. (3) The strength of the correlation between the functional area and passenger flow was revealed via data analysis using Pearson’s correlation coefficient. Finally, the findings of this study provide a valuable reference for research on similar topics in other countries that are developing station-city integration.

Authors: E. Satoh, R. Kasahara, T. Aoki, K. Fukatsu, D. Venkata Ramanarao, H. Harayama, T. Murata, A. Suwa

Abstract:

Rice plant hoppers (Hemiptera: Delphacidae) have been causing extensive economic damage in rice and are considered as serious threat in rice producing countries of Asia. They have developed resistance to major groups of chemical insecticide, and severe outbreaks occur commonly throughout Asia. To control these nuisance pests, Nihon Nohyaku Co., Ltd., recently discovered an insecticide, benzpyrimoxan (proposed ISO name), which is under development as NNI-1501 (development code). Benzpyrimoxan has a unique chemical structure which contains benzyloxy and cyclic acetal groups on pyrimidine moiety (5-(1,3-dioxan-2-yl)-4-[4- (trifluoromethyl)benzyloxy]pyrimidine). In order to clarify the biological properties of benzpyrimoxan, we conducted several experiments and found the following results. Benzpyrimoxan has high activity against nymphal stages of rice plant hoppers without any adulticidal activity. It provides excellent and long lasting control against rice plant hoppers, including populations that have developed resistance to several other chemical groups of insecticide. The study on its mode of action is undergoing. These features highlight the versatility of this insecticide as an effective and valuable tool from the viewpoints of insecticide resistance management and integrated pest management program. With the use of benzpyrimoxan, farmers shall be able to lead the best yield potential by keeping the population density of rice plant hoppers and associated virus diseases under control.

2200 Bilingual Identities of Kuwaiti Students at Universities with EMI

Authors: Marta Tryzna, Shahd Al Shammari

Abstract:

Though Modern Standard Arabic (MSA) is the only official language in GCC states, including Kuwait, and traditionally the preferred vehicle for literacy in the Arab countries, recent studies in Qatar and the UAE observe a growing role of English, particularly in literacy and knowledge transmission contexts. The present study examines the attitudes to Arabic and English and the use of both languages in literacy-related domains based on a sample of bilingual Arabic-English undergraduates (N=522) at a private university with EMI in Kuwait. The results indicate that Arabic (Kuwaiti dialect) is associated with familial interactions, Arabic-English bilingualism predominates in interactions with classmates, friends, on social media and at work, while English is prevalent in literacy-related contexts such as reading books, magazines, or online material, domains traditionally associated with MSA. Attitudes towards Arabic and English are equally positive according to the majority of the respondents, who report being comfortable expressing themselves and projecting their identity in both languages. No statistically significant differences were found comparing the importance of Arabic and English in the sample. Future trends were identified based on high agreement on the importance of speaking English with children and low agreement on speaking only Arabic at home. The study corroborates recently observed trends in the GCC favoring bilingualism across personal, academic and professional domains, with English becoming the preferred language of literacy among young bilingual Kuwaitis.

2199 Impact of Mid-Day Meal on Nutritional Status of Primary School Children in Haryana, India

Authors: Vinti Davar

Abstract:

India is one among the many countries where child malnutrition is severe and also a major underlying cause of child mortality. The Mid Day Meal (MDM) program was launched to improve the nutritional status of children, attendance, and retention in schools. It was based on one meal provided to the children, who are attending elementary school (primary school). The objective of present study was to evaluate the impact of mid-day meal on the nutritional status of primary school children in Haryana, India. The present work was carried out on 1200 children between 6-11years of age, studying in primary schools in Haryana, India. Out of these 960 students as, the experimental group was selected from schools where mid-day meal is supplied by the government, and 240 students as control group where mid-day meal is not supplied. The mean height, weight, and BMI of children of both the groups were found to be significantly low as compared to NCHS standards. Stunting was found in 56.40% MDMB (Mid-day meal beneficiaries) and 62.50 % NMDMC (non- mid-day meal children).The weight of almost all subjects were low according to age indicating thinness. Anemia was more prevalent in MDMB as compared to NMDMC may be because school meals did not include vegetables. The consumption of energy, proteins, fat, calcium, iron, vitamins was significantly low (P ≤ .01) in both groups especially in girls of NMDM. The consumption of various food groups except vegetables was better in MDMB compared to NMDMC. It is concluded that with certain improvements, mid-meal can be beneficial in meeting everyday requirements of school going children.

2198 Assessment of the Economic Factors and Motivations towards De-Dollarization since the Early 2000s and Their Implications

Authors: Laila Algalal, Chen Xi

Abstract:

The US dollar has long served as the world's primary reserve currency. However, this dominance faces growing challenges from internal US economic pressures and the rise of alternative currencies. Internally, issues like high debt, inflation, reduced competitiveness, and economic instability due to inequality in economic policies threaten the dollar's position. Externally, more countries are establishing alternative currencies, payment systems, and regional financial institutions to reduce dollar dependence. These drivers have contributed to a decline in the dollar's share of global foreign exchange reserves from 71% in 2001 to an estimated 58% in 2022. While this 13-percentage point drop took two decades, recent initiatives suggest de-dollarization could accelerate in the coming few decades. Efforts to establish non-dollar trade deals and alternative financial systems show more substantial progress compared to initiatives in the early 2000s. As the nature of the world system is anarchic, states make either individual or group efforts to guarantee their economic security and achieve their interests. Based on neoclassical realism, this paper analyzes both internal and external US economic factors driving current and future de-dollarization and the implications on the international monetary system, in addition to examining the motivation for such moves.

In this investigation, the activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K, of some ceramic tile materials used in the local market of Jordan for interior decoration were determined by making use of High Purity Germanium (HPGe) detector. Twenty samples of the different countries of origin and sizes used in Jordan were analyzed. The concentration values of the last-mentioned radionuclides ranged from 30 Bq.kg⁻¹ (Sample from Jordan) to 98 Bq.kg⁻¹ (Sample from China) for ²²⁶Ra, 31 Bq.kg⁻¹ (Sample from Italy) to 98 Bq.kg⁻¹ (Sample from China) for ²³²Th, and 129 Bq.kg⁻¹ (Sample from Spain) to 679 Bq.kg⁻¹ (Sample from Italy) for ⁴⁰K. Based on the calculated activity concentrations, some radiological parameters have been calculated to test the radiation hazards in the ceramic tiles. In this work, the following parameters: Total absorbed dose rate (DR), Annual effective dose rate (HR), Radium equivalent activity (Raeq), Radon emanation coefficient F (%) and Radon mass exhalation rate (Em) were calculated for all ceramic tiles and listed in the body of the work. Fortunately, the average calculated values of all parameters are less than the recommended values for each parameter. Consequently, almost all the examined ceramic materials appear to have low radon emanation coefficients. As a result of that investigation, no problems on people can appear by using those ceramic tiles in Jordan.

2196 Prototype of Low-Cost Safety-Suit for Manual Scavengers in India

Authors: Noopur Anand, Amit Gupta

Abstract:

Sewage divers are the workers involved in cleaning and maintaining of the sewerage lines by entering through manholes. The working conditions of sewage divers in India are more challenging than in other countries. Though India has legal acts framed to ensure protection of the divers called 'The Prohibition of Employment of Manual Scavengers and their Rehabilitation Act, 2013' by Ministry of Law and Justice but these are usually not implemented. Further, the divers are not even provided with safety gear like mask, eyewear, helmet, safety suit, safety belt, gloves, and shoes because of lack of initiative among the agencies/individuals employing them and low awareness of importance of the protective gear amongst workers themselves. Several reports and studies show that because of the non-availability of safety gear, many sewage workers get infected and many of them retire even before attaining superannuation and about 70% of the manual scavengers die while on job. Though there are neoprene safety suits, costing only a few thousand, available in the market which can suffice but is beyond the buying capacity of the sewage diver and agencies/individuals employing them are reluctant to procure it as they find it expensive. In absence of safety suits, the divers get exposed to the parasites, viruses, and disease-causing germs present in the sewage. The research was undertaken with the objective of developing an affordable safety-suit which would save diver from coming into direct contact with the sewage thus preventing infections and diseases. The low cost of the suit may also motivate their employers to procure them for sewage divers.

2195 Clustering of Natural and Nature Derived Compounds for Cardiovascular Disease: Pharmacophore Modeling

Authors: S. Roy, R. Rekha, K. Sriram, G. Subhadra, R. Johana

Abstract:

Cardiovascular disease remains a leading cause of death in most industrialized countries. Many chemical drugs are available in the market which targets different receptor proteins related to cardiovascular diseases. Of late the traditional herbal drugs are safer when compared to chemical drugs because of its side effects. However, many herbal remedies used in treating cardiovascular diseases have not undergone scientific assessment to prove its pharmacological activities. There are many natural compounds, nature derived and Natural product mimic compounds are available which are in the market as approved drug. In the most of the cases drug activity at the molecular level are not known. Here we have categorized those compounds with our experimental compounds in different classes based on the structural similarity and physicochemical properties, using a tool, Chemmine and has attempted to understand the mechanism of the action of a experimental compound, which are clustered with Simvastatin, Lovastatin, Mevastatin and Pravastatin. Target protein molecule for Simvastatin, Lovastatin, Mevastatin and Pravastatin is HMG-CoA reductase, so we concluded that the experimental compound may be able to bind to the same target. Molecular docking and atomic interaction studies with simvastatin and our experimental compound were compared. A pharmacophore modeling was done based on the experimental compound and HMG-CoA reductase inhibitor.

2194 Networked Media, Citizen Journalism and Political Participation in Post-Revolutionary Tunisia: Insight from a European Research Project

Authors: Andrea Miconi

Abstract:

The research will focus on the results of the Tempus European Project eMEDia dedicated to Cross-Media Journalism. The project is founded by the European Commission as it involves four European partners - IULM University, Tampere University, University of Barcelona, and the Mediterranean network Unimed - and three Tunisian Universities – IPSI La Manouba, Sfax and Sousse – along with the Tunisian Ministry for Higher Education and the National Syndicate of Journalists. The focus on Tunisian condition is basically due to the role played by digital activists in its recent history. The research is dedicated to the relationship between political participation, news-making practices and the spread of social media, as it is affecting Tunisian society. As we know, Tunisia during the Arab Spring had been widely considered as a laboratory for the analysis the use of new technologies for political participation. Nonetheless, the literature about the Arab Spring actually fell short in explaining the genesis of the phenomenon, on the one hand by isolating technologies as a casual factor in the spread of demonstrations, and on the other by analyzing North-African condition through a biased perspective. Nowadays, it is interesting to focus on the consolidation of the information environment three years after the uprisings. And what is relevant, only a close, in-depth analysis of Tunisian society is able to provide an explanation of its history, and namely of the part of digital media in the overall evolution of political system. That is why the research is based on different methodologies: desk stage, interviews, and in-depth analysis of communication practices. Networked journalism is the condition determined by the technological innovation on news-making activities: a condition upon which professional journalist can no longer be considered the only player in the information arena, and a new skill must be developed. Along with democratization, nonetheless, the so-called citizen journalism is also likely to produce some ambiguous effects, such as the lack of professional standards and the spread of information cascades, which may prove to be particularly dangerous in an evolving media market as the Tunisian one. This is why, according to the project, a new profile must be defined, which is able to manage this new condition, and which can be hardly reduced to the parameters of traditional journalistic work. Rather than simply using new devices for news visualization, communication professionals must also be able to dialogue with all new players and to accept the decentralized nature of digital environments. This networked nature of news-making seemed to emerge during the Tunisian revolution, when bloggers, journalists, and activists used to retweet each other. Nonetheless, this intensification of communication exchange was inspired by the political climax of the uprising, while all media, by definition, are also supposed to bring some effects on people’s state of mind, culture and daily life routines. That is why it is worth analyzing the consolidation of these practices in a normal, post-revolutionary situation.

2193 Application of ANN for Estimation of Power Demand of Villages in Sulaymaniyah Governorate

Authors: A. Majeed, P. Ali

Abstract:

Before designing an electrical system, the estimation of load is necessary for unit sizing and demand-generation balancing. The system could be a stand-alone system for a village or grid connected or integrated renewable energy to grid connection, especially as there are non–electrified villages in developing countries. In the classical model, the energy demand was found by estimating the household appliances multiplied with the amount of their rating and the duration of their operation, but in this paper, information exists for electrified villages could be used to predict the demand, as villages almost have the same life style. This paper describes a method used to predict the average energy consumed in each two months for every consumer living in a village by Artificial Neural Network (ANN). The input data are collected using a regional survey for samples of consumers representing typical types of different living, household appliances and energy consumption by a list of information, and the output data are collected from administration office of Piramagrun for each corresponding consumer. The result of this study shows that the average demand for different consumers from four villages in different months throughout the year is approximately 12 kWh/day, this model estimates the average demand/day for every consumer with a mean absolute percent error of 11.8%, and MathWorks software package MATLAB version 7.6.0 that contains and facilitate Neural Network Toolbox was used.

Authors: Victoria Appatova

Abstract:

internal and external, that are largely shaped by the student’s perceptions. Since 2006, the ELE concept has been studied by an international group of scholars through the creation of an ELE survey which was administered in nine countries and translated into five languages. The survey compares students’ perceptions of their learning environments and self-efficacy across A student’s effective learning environment (ELE) is comprised of multiple factors, both cultures as well as distinguishes similarities and differences in the students’ needs related to their learning. The main objectives of this international project include the following: Determine a system of components constituting ELE from the perspective of students and other academic populations Analyze students’ expectations, and their chances to succeed in college based on their expectations Conceptualize a comprehensive approach for assessing the effectiveness of a learning environment Compare the actualization of the ELE concept in American schools versus other national educational systems Compare student perceptions of ELE with those of faculty, administrators, and professional staff Four major factors influencing student learning across cultures and various national educational systems were determined: students’ initiative in using support services; learning skills; external comfort; and curriculum. Recent changes in the students’ perceptions, resulting from technology advances and a rapid shift to online learning, are being explored. The findings call for administrative and pedagogical actions which would cultivate more equitable education systems.

2191 Content Analysis of Images Shared on Twitter during 2017 Iranian Protests

Authors: Maryam Esfandiari, Bohdan Fridrich

Abstract:

On December 28, 2017, a wave of protests erupted in several Iranian cities. Protesters demonstrated against the president, Hasan Rohani, and theocratical nature of the regime. Iran has a recent history with protest movements, such as Green Movement responsible for demonstrations after 2009 Iranian presidential election. However, the 2017/2018 protests differ from the previous ones in terms of organization and agenda. The events show little to no central organization and seem as being sparked by grass root movements and by citizens’ fatigue of government corruption, authoritarianism, and economic problems of the country. Social media has played important role in communicating the protests to the outside world and also in general coordination. By using content analyses, this paper analyzes the visual content of Twitter posts published during the protests. It aims to find the correlation between their decentralized nature and nature of the tweets – either emotionally arousing or efficiency-elicit. Pictures are searched by hashtags and coded by their content, such as ‘crowds,’ ‘protest activities,’ ‘symbols of unity,’ ‘violence,’ ‘iconic figures,’ etc. The study determines what type of content prevails and what type is the most impactful in terms of reach. This study contributes to understanding the role of social media both as a tool and a space in protest organization and portrayal in countries with limited Internet access.

2190 A Structural Constitutive Model for Viscoelastic Rheological Behavior of Human Saphenous Vein Using Experimental Assays

Authors: Rassoli Aisa, Abrishami Movahhed Arezu, Faturaee Nasser, Seddighi Amir Saeed, Shafigh Mohammad

Abstract:

Cardiovascular diseases are one of the most common causes of mortality in developed countries. Coronary artery abnormalities and carotid artery stenosis, also known as silent death, are among these diseases. One of the treatment methods for these diseases is to create a deviatory pathway to conduct blood into the heart through a bypass surgery. The saphenous vein is usually used in this surgery to create the deviatory pathway. Unfortunately, a re-surgery will be necessary after some years due to ignoring the disagreement of mechanical properties of graft tissue and/or applied prostheses with those of host tissue. The objective of the present study is to clarify the viscoelastic behavior of human saphenous tissue. The stress relaxation tests in circumferential and longitudinal direction were done in this vein by exerting 20% and 50% strains. Considering the stress relaxation curves obtained from stress relaxation tests and the coefficients of the standard solid model, it was demonstrated that the saphenous vein has a non-linear viscoelastic behavior. Thereafter, the fitting with Fung’s quasilinear viscoelastic (QLV) model was performed based on stress relaxation time curves. Finally, the coefficients of Fung’s QLV model, which models the behavior of saphenous tissue very well, were presented.

2189 Electricity Sector's Status in Lebanon and Portfolio Optimization for the Future Electricity Generation Scenarios

Authors: Nour Wehbe

Abstract:

The Lebanese electricity sector is at the heart of a deep crisis. Electricity in Lebanon is supplied by Électricité du Liban (EdL) which has to suffer from technical and financial deficiencies for decades and proved to be insufficient and deficient as the demand still exceeds the supply. As a result, backup generation is widespread throughout Lebanon. The sector costs massive government resources and, on top of it, consumers pay massive additional amounts for satisfying their electrical needs. While the developed countries have been investing in renewable energy for the past two decades, the Lebanese government realizes the importance of adopting such energy sourcing strategies for the upgrade of the electricity sector in the country. The diversification of the national electricity generation mix has increased considerably in Lebanon's energy planning agenda, especially that a detailed review of the energy potential in Lebanon has revealed a great potential of solar and wind energy resources, a considerable potential of biomass resource, and an important hydraulic potential in Lebanon. This paper presents a review of the energy status of Lebanon, and illustrates a detailed review of the EDL structure with the existing problems and recommended solutions. In addition, scenarios reflecting implementation of policy projects are presented, and conclusions are drawn on the usefulness of a proposed evaluation methodology and the effectiveness of the adopted new energy policy for the electrical sector in Lebanon.

2188 A Study of Welfare State and Indian Democracy by Exploration of Social Welfare Programmes in India

Authors: Kuldeep Singh

Abstract:

The present paper is an attempt for tracing the changes in the welfare state in Indian democracy from the starting point till now and aims to critical analyse the social-welfare programmes in India with respect to welfare state. After getting independence from Britishers, India became a welfare state and is aiming towards the upliftment of its citizens. Indian democracy is considered to be the largest amongst democratic countries, instead of this after forty-five years of independence, Panchayati Raj Institution became one of the branches of democratic decentralization institutions in India by 73rd and 74th Constitutional Amendment in 1992. Unfortunately, desired purpose of introducing Panchayati Raj Institution is not achieved after all these delayed efforts. The basic problem regarding achievement of welfare state in India in true sense is unawareness and non-implementation of these social-welfare programmes. Presently, Indian government is only focusing on economic growth of the country but lacking from the social point. The doctrinal method of research is used in this research paper. In the concluding remarks, researcher is partly favoring the government in introducing welfare programmes as there are abundant of welfare schemes and programmes, but majority are facing implementation problem. In last, researcher has suggested regarding programmes and schemes that these should be qualitative in nature and power would be given to effective machinery for further check upon their proper implementation and aware the citizens regarding their rights so that welfare state would be achieved.
