Exploring Semantic Interoperability in e-Government Interoperability Frameworks for intra-African collaboration: A Systematic Literature Review

While many African countries have called for ICT based intra-African collaboration, services, and trade, it is not known whether this call is technically feasible. For such intra-African based collaboration, semantic interoperability would be required between the national e-government systems. This paper reviewed the e-government interoperability frameworks (e-GIFs) of English and Arabic speaking African countries to identify the evidence and conflict approaches to semantic interoperability. The results suggest that only seven African countries have e-GIFs, which have mainly been adopted from the UK\u27s e-Government Metadata Standards (eGMS) and on Dublin\u27s Core metadata (DC). However, many of the e-GIFs, with the exception of Nigeria, have not been contextualized to the local needs. The paper, therefore, concluded that more effort needs to be placed in developing e-GIFs in Africa, with particular emphasis on semantic interoperability, if the dream of intra-African collaboration is to be achieved

An Empirical Investigation of the UAE Stock Markets.

This thesis consists of six chapters. The first provides an overall introduction. The second offers a retrospective review of the development of the financial markets in the UAE from their start until now. The third chapter investigates empirically the casual nexus of the Abu Dhabi and Dubai stock markets in order to assess the degree of integration between these two domestic markets. To our best knowledge, this is the best attempt to explore domestic financial market integration within the context of the UAE. The fourth chapter extends the analysis in order to examine the degree of financial market integration of the UAE with regards to the global market. The fifth chapter deals with the impact of the recent real estate financial crisis on the UAE real estate market, which is considered an important sector for the economic development of the country. Chapter 6 examines the dynamic impact of oil prices on the stock market. Our methods consist of both symmetric and asymmetric causality tests, which are used in Chapters 3-6. When testing for causality, we do not make any distributional assumptions. We generate critical values via bootstrap simulations with leverage adjustments. This approach is expected to be more accurate since the underlying data set is usually non-normal with time varying volatility. We also make use of the asymmetric generalized impulse response functions in Chapter 5 and the last chapter. Allowing for asymmetric impacts is considered to be in line with the way that markets generally operate since it is widely agreed that people in the financial world tend to react more to negative news than positive news. Our conjecture is that the empirical findings which this thesis offers can be useful to both investors and policy makers in the UAE

Effects of Water Harvesting Techniques in Dry Lands on Establishment of Faidherbia albida (Del.) A. Chev. Seedlings in Nyala Locality, South Darfur State

This study aimed to assess the effects of water harvesting techniques on the establishment of Faidherbia .albida seedlings in dry lands of two sites (Savanna and Musai) in Nyala Locality, South Darfur State. The study was conducted during May 2010 to March 2011. Five water-harvesting techniques; namely, control, Trapezoidal bund, contour bund, semi-circular bund, and Negarim micro-catchments, were tested. Three months old F. albida seedlings, representing each treatment, were transplanted in prepared holes in August 2010. Seedlings height, diameter and number of branches were measured monthly from transplanting until the termination of the experiment in March 2011. Soil moisture content was determined at depths of 0-30 and 30-60 cm for all treatments in the two sites. The results showed that the seedlings height and diameter and number of branches were significantly better in the semi-circular bund compared with the control and the other techniques. The survival rate of F. albida seedlings was very low in the control and was the best in the semicircular bund in the Savanna site. In Musai site, the survival rate of seedlings in all the treatments was similar. The results of the soil moisture content showed that the semi-circular technique was the best in collecting and preserving water in Savanna site, while the contour bund was the best treatment in the Musai site

Barriers of Knowledge Transfer between Globally Distributed Teams in ICT Product Development

Increased globalization has generated a growth of globally distributed teams, which are characterized by geographical distance and used by organizations to increase innovation. However, to be able to collaborate effectively, teams are obligated to continuously conduct knowledge transfer (KT) between different geographical locations. Thus, this paper focused on identifying the main barriers that globally distributed teams face in conducting KT and how these barriers are unraveled. Based on an interpretative case study of a product development unit (PDU) in research and development (R&D) department of a telecom company, we identified eight main barriers that hinder the KT between globally distributed teams. These barriers are; knowledge embeddedness, knowledge accessibility and documentation gaps, knowledge complexity, knowledge problematic articulability, ICT tools reliance vs. face to face, inefficient ICT tools utilization, inefficient IT support, and lack of formal processes and guidelines

Knowledge and Attitude of Population Towards Iodized Salt in Shendi Locality River Nile State in Sudan

Background: Iodine is observed as one of the most important trace elements in the human body, which is considered very essential during the synthesis of thyroid hormones. Iodine deficiency in humans can cause several diseases or problems, which include spontaneous abortion, increased infant mortality, cretinism, goiter, and mental defects. Methods: The study was conducted as a community based descriptive crosssectional study to determine the knowledge and attitude of the population towards iodized salt in Shendi locality, River Nile State, Sudan, during the period of 2013. In this study, 636 households were included. Questionnaire and observations were used as tools for data collection. The households were selected through a multistage cluster-sampling technique, 636 respondents were selected through systemic random sampling. Results: The study found that the knowledge of the respondents about iodized salt was poor. Out of 636 subjects, 356 (56%) were aware of iodine as a nutritional element. 279 (43.9%) identified that iodine is a chemical element. More than half of the respondents, 355(55.8%), were aware of sources of iodine in foods. The data showed that 299 (47%) of the respondents were aware of the main type of food which contains iodine. 356(56%) were aware of the fact that iodine deficiency had significant influence on the body. In addition, study revealed that 261(41%) of participant were aware of iodized salt. Only 48% of the population knew that iodized salt is necessary to alleviate iodine deficiency disorder. Conclusion: Based on our findings, we conclude that the household has poor knowledge, negative attitude, and poor practice about iodized salt. Hence, health authority should have to develop health education programs to increase the awareness of households about the significance of iodized salt. Also, it involves a proper handling of a continual and effective use of media for broadcasting health education programs

Computer aided photographic memory enhancement and speed reading (case study)

This work aimed to design and testing of a computer program – based eyeQ improvement, photographic memory enhancement, and speed reading to match the reading speed 150 – 250 word per minute (WPM) with the mind ability of processing and eye snap shooting 5000WPM . The package designed based on Visual Basic 6. The efficiency of the designed program was tested on a 10 persons with different levels of education and ages and the results show an increase in their reading speed of approximately 25% in the first month of training with noticeable enhancement in the memory as well as an increase in the ability to read for longer time without feeling nerves or boring, a nonlinear continuously increase in reading speed is assured after the first month with a hope of reaching a target of 3000WPM within 3 – 5 years of training and that is what is called photographic memory where most of the read data processed in right side of the mind, the smaller age, and higher level of education is an effective factor on the results

Distance based Modelling and Optimization of Wireless Sensor Network Energy Consumption with Adaptive Clustering using Genetic Algorithm

Wireless sensor network (WSN), as one of the most important technologies due to its wide variety of applications, consists of various densely deployed sensor nodes inside or very near to application area. WSNs work with several limitations related to resources like battery power, bandwidth, memory and etc. and hence node goes out of energy where it's impossible to recharge or replace the battery of nodes. It has been proved that, long communication distance between sensor nodes and base station (BS) can drain the energy. This paper proposes an approach to optimize the WSN energy consumption of nodes via optimizing the number of clusters that minimizes the transmission distance, for maximizing network lifetime. A genetic algorithm is proposed for sensor nodes clustering to find the optimal number of cluster heads that reduces the energy consumption. The proposed solution considers the communication distance, as a main factor, which is formulated as an objective function to be optimized for the mathematical model constrained by the number of cluster heads. The results were conducted using the proposed GA for different instances with different settings such as the population size, number of cluster-heads, and number of generations. The experimental results show that the algorithm achieved good results and it converges toward the optimal solution through the generations for the different instances. Moreover, the proposed approach reduces the energy consumption more efficient when compared with hierarchical clustering algorithm on minimizing the communicating distance. It is recommended to scale the algorithm to consider a trade-off between the total intra-cluster communication distance and total distance of cluster-heads to BS as a future work

La prevalencia del desgaste dental entre un grupo de adultos Yemeníes.

This study aimed at investigating tooth wear prevalence and determining the associated factors among a group of Yemeni adults. It is a preliminary cross-sectional and analytical investigation conducted on 600 participants aged 20–50 years. The participants were purposively selected from two main cities (Sana’a and Aden) with an equal sample size and divided equally by gender. For administering a questionnaire, interviews were conducted with all participants before clinically examining them. Using the Tooth Wear Index (TWI), tooth wear was assessed. Data were analyzed using the chi-square test to identify the relationship between tooth wear and associated factors., Tooth wear was prevalent among 78.67% of the participants; of which 64.83% were in anterior teeth, 63.83% in posterior teeth, 74% in maxillary teeth, and approximately 74.5% in mandibular teeth. It also was 100% prevalent in the 31-40 and 41-50 age groups, while it was 67.2% in the 20-30 age group. This showed that tooth wear prevalence was significantly higher in the two oldest groups than in the youngest group (p<0.001). Moreover, khat chewing, location, highly frequent consumption of foods and high frequency of acidic drinks consumption were critical indicators of tooth wear. Besides, a low education level, smoking and a low socio-economic status were associated with tooth wear. Finally, the study revealed that tooth wear is highly prevalent among adults in two Yemeni cities, and socio-behavioral risk indicators such as khat chewing and cigarette smoking have a significantly association with tooth wear.Este estudio tuvo como objetivo investigar la prevalencia del desgaste dental y determinar los factores asociados en un grupo de adultos yemeníes. Es una investigación preliminar analítica y transversal que se lleva a cabo en 600 participantes de entre 20 y 50 años. Los participantes fueron seleccionados a propósito de dos ciudades principales (Sana’a y Aden) con un tamaño de muestra igual y divididos por igual por género. Para administrar un cuestionario, se realizaron entrevistas con todos los participantes antes de examinarlos clínicamente. Usando el Índice de Desgaste Dental, se evaluó el desgaste dental. Los datos se analizaron utilizando la prueba de chi-cuadrado para identificar la relación entre el desgaste dental y los factores asociados. El degaste dental tuvo una prevalencia del 78,67% de los participantes; de los cuales 64.83% en dientes anteriores, 63.83% en dientes posteriores, 74% en dientes maxilares y aproximadamente 74.5% en dientes mandibulares. Fue 100% prevalente en los grupos de edad 31-40 y 41-50, mientras que la prevalencia fue 67.2% en el grupo de edad 20-30. Esto demostró que la prevalencia del desgaste dental fue significativamente mayor en los dos grupos de personas mayores que en el grupo más joven (p<0.001). Además, mascar khat, la ubicación, el consumo muy frecuente de alimentos y la alta frecuencia de bebidas ácidas fueron indicadores críticos del desgaste dental. Además, el bajo nivel educativo, el tabaquismo y el bajo nivel socioeconómico se asociaron con el degaste dental. Finalmente, el estudio reveló que el desgaste dental es altamente prevalente entre los adultos en dos ciudades yemeníes, y los indicadores de riesgo socioconductual como la masticación de khat y el tabaquismo tienen una asociación significativa con el desgaste dental
