Service-Oriented Architecture (SOA) provides a flexible framework for service composition. Using standard-based protocols (such as SOAP and WSDL).There are several constraints meant for selecting the right and appropriate service to be designed as reconfigurable dynamic web services. Those constraints leverage to the following factors availability, response time, failure handling and supports dynamic configuration. Our paper presents the way of predicting the service methods which are really necessary for providing as a dynamic web service. Since all the service methods cannot be used as dynamically as it depends upon the number of users really using the service by the service providers.
The article aims at contributing to the debate about the introduction of ICT in social services with a reflection that, on the basis of the development of the ISSS of the Italian Autonomous Region of Friuli Venezia Giulia , shows that it is possible to set up an information system fill to the particular nature of social work and, in particular, to its methodology of work and to the complexity of social needs and of the relationship between social services’ user and social worker. It points out that to get this result is important to give up the deterministic approach to technology as well as the centralized and top down approach to ISSS, and to adopt a relational approach to both these issues.
In contemporary civilized Nigeria, the Information Communication Technologies (ICTs) has become a household name used in offices and at homes to access, receive and retrieve information. Many innovations in the world today are as a result of the exposure and access to the world of the ICTs and people all over the world can access any other parts of the world to receive information about anything that borders on their interest in life. Women in their quest for empowerment and societal recognition have adopted and accepted ICT as an instrument for their advancement and empowerment. This is manifested in their previous two world conferences in Nairobi, 1985 and Beijing, 1995, where among several areas of concern, the role of the media in subordinating women featured prominently. But unfortunately, despite the much emphasis placed on the use of ICTs in Nigeria, women are often underrepresented in terms of access and use. It is against this background that this paper examines the challenges and prospects of ICT utilization among women in Nigeria. These challenges include lack of infrastructure, education and skills; urban-bias; and sociocultural and economic challenges.The study concludes that to address these gender gaps in ICTs in Nigeria, all hands must be on deck to change women’s attitudes towards ICT use by overcoming technophobia;women should be provided with educational and economic empowerment; government ICT policies and programs must address the needs of women;and the civil society should be part and parcel of this crusade for the betterment of women and the society at large.
Vegetation is an important component of the ecosystem that provides habitat for wildlife and maintains the functioning of the ecosystem. However, improper use of this vital natural resource by humans has undermined its integrity in meeting some of its objectives. Hence, there is the need to monitor and manage this important component of the ecosystem. This study therefore, assesses the application of different vegetation indices in the study of arid land vegetation dynamics. The results show that there is significant relationship between rainfall and NDVI at the 95 percent (p=0.05) level of significance while the other vegetation indices show no significant relationships in the period spanning 1972 and 2007. NDVI, GVI and TSAVI are the ones with strong negative linear correlations (r = -0.92, -0.75 and -0.77 respectively) with rainfall while PVI and WDVI have weak linear relationship with rainfall. (r = 0.15 and 0.29). This means that rainfall is not the major determinant of vegetation cover dynamics in the study area in spite of increase in rainfall between 1972 and 2007. It thus appears that other factors like human activities might have influenced the changes in vegetation cover of the study area.
Using a two (2) factors model, this research paper analyzes the impacts of both financial leverage and the size of firms’ competitors in the construction industry on the market risk level of 104 listed companies in this category. This paper founds out that the risk dispersion level in this sample study could be minimized in case financial leverage decreases down to 20% and the competitor size doubles (measured by equity beta var of 0,253). Beside, the empirical research findings show us that the risk level could be reduced when financial leverage increases up to 30% and the size of competitor doubles (measured by equity beta value of 0,934). Last but not least, this paper illustrates calculated results that might give proper recommendations to relevant governments and institutions in re-evaluating their policies during and after the financial crisis 2007-2011.
In this paper, we discuss about the recently collected sample of ground water at different locations at Ghazipur and its experimental analysis in laboratory for the presence of pH content. Also, we represents the data graphically and interpreted the data using the method called analysis of variance. Further, we analyze our findings with the established results. Lastly we concluded that the samples does not depend on locations but it depends on months.
Cocoa production is susceptible to a number of risks such as unavailability of enough land, unavailability of agro-chemicals, variation in product prices and a host of others. This study utilized game theory to determine the cocoa production management system which maximizes the income of farmers under risks. Data on cocoa production were collected from a random sample of 200 farmers practicing the three cocoa production management systems viz: Owner management system, Lease management system as well as Sharecropped management system. The games were constructed based on the income per hectare obtained from each of the three management systems. Maximax and Maximin criteria of game theory were used in the analysis. The Maximax criterion showed that the best management system to practice by cocoa farmers was Sharecropped management system (Income per hectare of N214,847) while the result of the Maximin showed that the best management system was Owner management system ( Income per hectare of N92,463). The study therefore recommended for optimistic farmers to practice Sharecropped management system while Owner management system is recommended for pessimistic farmers.
Recursive algorithms analysis by generated trees node counting refers to detailed study of their structures. In this connection the paper presents the specific description of peculiar to a number of recursive algorithms regular trees. We have developed the method which is based on introduced regular description and provides an analytical solution for a number of generated nodes at such regular tree each level. The results obtained make possible a theoretical time complexity analysis of recursive algorithms generating regular recursion trees.
For many years the trichrome staining technique (TricrómicWheatley) has been considered as the most important technique for the identification ofthe most common intestinal protozoa and popularin parasitology (1). Currently the mostsensiblidad procedure for detecting and identifying protozoa trophozoites stool sample as it helps to easily highlight the morphology of amoebic cysts and trop-hozoites however, the procedure is complicated and tediousto perform and require at seven different reagents which is probably the most critical especially in laboratories with limited staff, this makes it complicated the routine use of this technique in most of the clinical laboratory, using koplic additionally facilitates reagent contamination by repeated use.(4,5)
Background : Though POSSUM and P-POSSUM have been proposed as accurate tools of audit, our initial experience has not been encouraging. Therefore, a prospective study was conducted to find their accuracy for predicting outcome in peritonitis patients who underwent emergency laparotomy. Methods : 172 patients treated in single surgical unit over two years were included. Expected morbidity and mortality, computed by POSSUM and P-POSSUM equations using linear as well as exponential methods of analysis, were compared with observed outcome by observed: expected (O:E) ratios. X2-test was done to draw statistical significance; P<0.050 was taken as significant. Results : POSSUM significantly over-predicted mortality with linear as well as exponential methods with O:E ratios being 0.32 (X2=57.35, 1 d.f. P<0.001) and 0.25 (X2=111.26, 1 d.f. P<0.001), respectively. P-POSSUM also significantly over-predicted mortality by linear as well as exponential methods with O:E ratios being 0.55 (X2=11.37, 1 d.f. P<0.001) and 0.27 (X2=92.30, 1 d.f. P<0.001), respectively. POSSUM significantly over-predicted morbidity by linear and exponential analysis with O:E being 0.76 (X2=47.94, 1 d.f. P<0.001) and 0.81 (X2=23.27, 1 d.f. P<0.001), respectively. Conclusions : Neither POSSUM nor P-POSSUM was found accurate for predicting the outcome by linear or exponential methods. Further studies are required to find their suitability for audit purposes in conditions prevailing in third world countries.
