Mobile LearningPlatform: a case study of introducing m-learning in Tertiary Education
Get PDFThis paper presents a study on a one year m-learning pilot project at Central University College in Ghana. This was done through a user trial, where the m-learning tool AD-CONNECT is introduced in 44 courses with a total of 500 students and 22 lecturers at the College. The paper reports on the first experiences gained by both teachers and students by asking the following questions: What are the perceptions of teachers on m-learning? What are the effects of m-learning on students? What does m-learning contribute to face-to-face teaching and learning? Questionnaires were administered to students and lecturers to gather quantitative data on their views on the use of m-learning, particularly after using the AD-CONNECT M-Learning system. Also, observations and interviews were used to collect data from users which provided us with some qualitative data
The Impact of Social Influence and Trust on Customer-to-Customer Online Shoppers’ Purchase Intention: An Empirical Study in Indonesia
Get PDFCustomer-to-customer (C2C) electronic commerce is agrowing area of e-commerce. It is facilitated in large part bywebsites offering free classified advertisement, auctions, forumsand individual pages for small-medium sized and start-upentrepreneurs. What factors are affecting C2C online shoppers’Purchase intention? To answer this question, a theoreticalframework was formed and tested using multiple regression on196 Indonesian customers collected via a Web survey. The resultsshow that social influence and trust are key predictors of purchaseintention in C2C e-commerce. These findings also indicate, basedon gender, only social influence has a significant difference. Whilebased on age, it reveals that only trust has no significant difference.This suggests that to facilitate C2C online shopping, marketplaceor C2C stores need to enhance social influence and develop moretrust as well as take into account shoppers’ perception based ongender and age
Masterpieces of Muslim Philosophers
No full textLocating masterpieces by Muslim philosophers in the field of philosophy is a challenge for several reasons: the interconnectedness between human knowledge as a discipline, and that this theme cannot be innovative. In addition, in order to understand the roots of philosophy within the Arab cultural environment and its development it is necessary to examine the history of Arab culture. Arab culture can trace its origins back thousands of years to the Mesopotamian, Pharaonic, and Saba and Himyar Civilizations.Although these civilizations witnessed the birth of streams of thought that can be considered philosophy, the word philosophy itself was not used because it is a Greek word. Despite the fact that philosophy dates to Ancient Greece, it is considered modern in comparison with the civilizations of Mesopotamia and Pharaonic Egypt. Thus, it is more accurate to refer to the beliefs developed by these civilizations as thought and not philosophy. Indeed, the word philosophy only came to be applied to Arab culture with the arrival of Al Kindi (801- 870 CE).When examining the use of the term philosophy in the context of Arab culture, we will determine the meaning of the word and explain how it was defined in ancient times; specifically, whether the sources that Muslim philosophers relied upon were Greek or other sources.This paper comprises only an introduction, describing the multiple approaches and the achievements conferred upon Muslim philosophers. It will take the form of an encyclopedia style entry to establish a foundation for researchers wishing to explore the achievements of Muslim philosophers
Numerical Study on Roadway Stability under Weak Geological Condition of PT Gerbang Daya Mandiri Underground Coal Mine in Indonesia
Get PDFThis paper aims to assess the roadway stability of the PT Gerbang Daya Mandiri (GDM) underground coal mine. A numerical analysis method using 3D finite difference code (FLAC 3D) was used to investigate the failure zone behavior of the roadway at various overburden depths (50 m, 100 m, 200 m, and 300 m). The outcome of this research was the most appropriate support system of the roadway. The results of numerical analyses indicated that the excavation depth affected the thickness of failure zone, and the capacity of the support system was significantly associated with an increase of the overburden depth. Steel set, cablebolt, and rockbolt supports were assessed in this paper. The steel set is selected as the main support system in GDM coal mine, and it is effective to stabilize the roof and sidewalls of the roadway until 200 m depth. As the failure zone becomes larger at the deeper sites, the cablebolt support is introduced to control the floor stability, and the use of rockbolt in combination with steel set is suggested to support the roof and sidewalls
The Use of OSCE to Predict the Future Work Performance of Singapore Nursing Students
Get PDFThe objective structured clinical examination (OSCE) was first introduced by Dr. Ronald Harden in 1970s to deal with the lack of objectivity and consistencies in clinical competence assessment among examiners due to the varied conditions within the real clinical workplace. OSCE has emerged as an authentic assessment method for evaluating clinical competence in doctors and other health professionals. Although OSCE has been widely researched on within the medical literature in terms of psychometric testing, there is a paucity of studies which report the development of OSCE as a summative examination within nursing education. This study reports the development of the OSCE instrument to measure final-year nursing students’ clinical competence at the end of a three-year nursing diploma program, and predict their future work performance, also referred to as readiness for practice, at the end of a six-month post-registration internship at hospitals in Singapore. The findings showed that OSCE can be a valuable assessment method to measure clinical competence and predict future work performance. The OSCE can also be used by nurse educators to determine learning gaps and provide remedial training for ‘under-performing’ graduating student while nursing administrators can use it to evaluate the clinical competence of foreign trained nurses as part of the interview process for recruitment and selection purposes
An Empirical Study of a Hybrid Code Clone Detection Approach on Java Byte Code
Get PDFCode clones increase the complexity of the system;therefore the software maintenance costs. Code clonedetection techniques have been proposed and evaluated basedon metric value and runtime evaluations. But in the existingmethods, many false positive clones are detected. In thispaper, we suggest a hybrid approach combining ProgramDependence Graph-based technique with Metric-basedtechnique to improve the precision of clone detection. Weconduct a case study on two open source code Java projectssuch as Eclipse-ant and Eclipse-JDT core to show the effectiveness of our tool. The application of this hybrid technique is then compared with the existing clone detection technique, CloneDR. The result shows that our tool increases the performance in precision, recall, false positive and false negative compared to CloneDR
Comparison of Some Approaches to Determine Spatial Dependence of Soil Properties
Get PDFKnowledge of variability and spatial structure of soil properties is essential for optimal design for collecting soil samples and effectively applying management decisions in the field. The objective of this study is to compare some approaches for characterizing, and comparing spatial dependence of isotropic second-order stationary processes. The evaluated approaches are the nugget to sill ratio (NR), normalized (by fitted sill) semivariogram, correlograms, and two integral scales. Soil samples, collected at a regular 50 m × 50 m grid from 0-15 cm depths, were analyzed for sand and clay, bulk density (ï²b), saturated hydraulic conductivity (Ks), wilting point, available water content (AWC), pH, electrical conductivity (EC), nitrate-nitrogen (NO3- N), and chloride (Cl) were determined. Geostatistical software (GS+, Gamma Design Software, Plainwell, MI) was used to estimate the variance structure of various measured soil properties. Analysis include using data on the spatial variability of various properties from four published studies. NR displayed spatial dependence ignoring the influence of range, normalized semivariogram and correlogram provided the visual comparison, and both integral scales incorporated the influence of range and provided single number spatial dependence summaries. Either of the integral scale formulations can be used to characterize the spatial dependence of soil properties from agricultural fields
An Urban Biom as an Alternative to Sustainable City.
No full textUsing the idea of sustainability in terms of not havingany alternative forms of modern town planning gives a falseimage of the only chance humanity has to overcome the problemof urban withering. The paper in to show the idea of urban biom/ urban polyspecific areas as a form of redeveloping cities in nonformaland non- technical way, which is nowadays associatedmostly with the idea of sustainability – energy and waterefficiency, green technologies of the future and so on. Biom is anew form of identifying green areas, not only as passive, butmostly active form of urban development basing not only on florabut also urban fauna, differing and depending on geographicregion in which the city is located. By leaving the idea ofprogrammed zoning of eco- cities a new kind of urban utilityzoning basing on the idea of biom is to be created.The beginning of change can be defined by technological,cultural, industrial, communication progress, which "liberated"large city areas or supported them for the inhabitants. Asignificant reduction of restricted zone area, excluded from use,but also occurring rapidly transformations of socio - politicalform, which are often the next stage of the industrial revolutionresulted in the need to formulate a new development policy ofthose empty spaces that remain in the place of former functions.Simultaneously one can observe differences in the modernapproach towards animals as a part of urban nature and theindependence of modern man from immediate animal work, butalso lack of having daily contact with them in various forms ofhumans' separation from nature
Analysis of Power and Dimensions of European Tractors
Get PDFThe tractor is an important machine for every European farmer. It is typically propelled by a Diesel-engine, while pure electric and hybrid drives gain interest. Only a few international manufacturers are manufacturing the enormous scope of tractor-models available on the European market. To save costs, several platform models have been established. They are labelled and sold under various brands. Therefore, 117 tractor models have been analyzed that were available on the Austrian market until the end of 2013. The aim was to identify if there are correlations of technical data (e.g. power and vehicle mass). Some additional values have been derived from them. It could be shown, that large tractors are equipped with relatively small sized tires. Large tractors generate higher pressure and shear stress in the contact area than small ones. A factor for the tire diameter was developed to obtain equal pressure and shear stress
The Responsiveness of International Tourists on Uncertainty and Instability: The Case Study of Inbound Tourists to ThailandNantarat
Get PDFThe purpose of this study is to examine the impact of uncertainty and instability factors as well as to recognize the determinants of the international tourism flows to Thailand. The study investigated the hypothesis that international tourists negatively respond to natural disasters, epidemic diseases, political unrest, and terrorism. The study uses panel data set during period 2003 – 2015 with 7020 observations. The data include the inbound tourists from East Asia, South Asia, Middle East, ASEAN, Europe, America, and Oceania. The results reveal that most of the variables in the model are statistically significant. Epidemic disease event counts immediately decrease tourist arrivals, but the effects will not extend to the next season. The study additionally found that terrorism event counts will delay the travel decision of tourists in the future. Tourists perceive more risk from the terrorism factor than others, so the factors prolong the impacts longer than other factors. The uncertainty and instability variables impact the tourist behaviors differently in different regions. Tourists from ASEAN and East Asia are more sensitive than other regions. The results reveal that all uncertainty and instability factors decrease the inbound tourists from these areas and extend the impact longer than other regions. The very same factors seem not to influence the travel decision of the tourists from South Asia, America, and Oceania
