Leveraging video annotations in video-based e-learning  [PDF]
Olivier Aubert,Yannick Prié,Camila Canellas
Computer Science , 2014,
Abstract: The e-learning community has been producing and using video content for a long time, and in the last years, the advent of MOOCs greatly relied on video recordings of teacher courses. Video annotations are information pieces that can be anchored in the temporality of the video so as to sustain various processes ranging from active reading to rich media editing. In this position paper we study how video annotations can be used in an e-learning context - especially MOOCs - from the triple point of view of pedagogical processes, current technical platforms functionalities, and current challenges. Our analysis is that there is still plenty of room for leveraging video annotations in MOOCs beyond simple active reading, namely live annotation, performance annotation and annotation for assignment; and that new developments are needed to accompany this evolution.
Leveraging Expert Systems Technology to Improve Service Industry
K. Metaxiotis
Asian Journal of Information Technology , 2012,
Abstract: Service industries are growing in importance in all over the world. These industries operate in a very competitive market where the need to differentiate a service from the competitor is analogous to survival. The effective use of information technology (IT) to help service companies improve service quality, financial performance, customer satisfaction and productivity is a very crucial issue nowadays. Intelligent solutions, based on expert systems (ES), to solve complicated practical problems in various sectors are becoming more and more widespread. However, the role of expert systems in the improvement of service industry has not yet been studied in the research community. In this framework, the primary objective of this paper is to discuss the important role that ES can play in the improvement of service industry. Based on the DPEAT (Diplomacy, Preparedness and Engagement responsibilities with the aid of Technology) model proposed by Agnihothri et al. we present how ES can be used in order to create an effective service organization. Carrying out ES-based DPEAT can result in superior service outcomes.

Journal of Sustainable Development , 2010, DOI: 10.5539/jsd.v3n3p3
Abstract: The Ontario feed-in tariff (FIT) for solar photovoltaic (PV) technology has provided Ontario's Aboriginal communities with an opportunity to i) weaken the cycle of poverty; ii) directly counteract climate change by producing renewable energy; and iii) become more self-sufficient. This paper critically analyzes the technical, cultural, and economic viability of leveraging the FIT for PV to provide green electricity and revenue to assist First Nations communities in sustainable development. A generalized free GIS-energy-based protocol was developed to determine the PV potential for Aboriginal communities. This model was applied to a case study of the Constance Lake First Nations community and an economic analysis showed financially-viable rates of return over 20 years. By generalizing these findings to Ontario, the potential PV deployment on First Nation rooftops alone is over 200MW, which clearly provides an opportunity for developing pride associated with owning a community-led, environmentally beneficial, local energy project.

International Journal of Engineering Research , 2013,
Abstract: Advances in mobile access broadband technology have a high potential to improve environmental sustainability both directly by enabling novel network deployment concepts and indirectly by changing the way people live and work. In this paper, improvements of the network topology enabled by broadband access are investigated. It is shown that a joint deployment of macro- and publicly accessible residential picocells can reduce the total energy consumption by up to 70% in urban areas. In addition the high potential of indirect effects of improving telecommunication networks, such as enabling teleworkingand replacing business travel through video conferencing, is demonstrated and compared with the direct effects.
Leverage Bubble  [PDF]

Quantitative Finance , 2010,
Abstract: Leverage is strongly related to liquidity in a market and lack of liquidity is considered a cause and/or consequence of the recent financial crisis. A repurchase agreement is a financial instrument where a security is sold simultaneously with an agreement to buy it back at a later date. Repurchase agreements (repos) market size is a very important element in calculating the overall leverage in a financial market. Therefore, studying the behavior of repos market size can help to understand a process that can contribute to the birth of a financial crisis. We hypothesize that herding behavior among large investors led to massive over-leveraging through the use of repos, resulting in a bubble (built up over the previous years) and subsequent crash in this market in early 2008. We use the Johansen-Ledoit-Sornette (JLS) model of rational expectation bubbles and behavioral finance to study the dynamics of the repo market that led to the crash. The JLS model qualifies a bubble by the presence of characteristic patterns in the price dynamics, called log-periodic power law (LPPL) behavior. We show that there was significant LPPL behavior in the market before that crash and that the predicted range of times predicted by the model for the end of the bubble is consistent with the observations.
Quality Practices as a Moderator in Technology Transfer Performance  [cached]

International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n7p96
Abstract: Absorptive capacity is one of the factors that determines the success of technology transfer. It improves one’s ability to assess the current and future needs of firms and leads them to make better choices. At the same time, quality movement in firms also has a similar vision; to make firms move forward in a competitive way. The objective of this paper is twofold. First, was to determine the association between absorptive capacity and technology transfer dimensions. Secondly, this study was conducted to determine the moderating role of firms’ quality practices in the relationship between firms’ absorptive capacity and technology transfer performance. Data was collected from Malaysian firms through mailed questionnaires. With a response rate of 32%, data was analyzed using multiple hierarchical regression and Chi Square method. The results showed quality process interacts significantly with knowledge diversification and transformative capacity during the integration stage. Moreover, the addition of a moderating variable increases the prediction of technology transfer performances. The result suggests firms’investment in quality practices improves the process of transferred technology.

Abstract: School leaders face challenges in using technology to upgrade teaching and learning processes in the twenty-first century as they must also become role models in its usage. Thus technology must be used not only for teaching and learning processes, but also in their organisational management. The aim of this research is first, to identify the level of technology leadership and competency in curriculum activity management among secondary school principals in Malaysia; second, to determine if technology leadership practices and curriculum activity management differ based on school location; third, to analyse if there is a correlation between technology leadership and competency of curriculum activity management. This quantitative style research used questionnaire for data collection involving 341 randomly selected Malaysian principals. Data collected was then analysed using descriptive and inference analysis. Findings show that Malaysian principals practice technology leadership at a very high level, and are also very competent at managing curriculum activity. T-test analysis found that urban principals’ technology leadership practices are significantly higher than their rural counterparts, but their curriculum management competencies are at the same level. Findings also show that there is a low yet significant correlation between technology leadership and curriculum management competencies. In light of this information, we recommend further in-depth studies to explore the rural-urban gap technology leadership scenario, thus finding possible solutions in narrowing the academic achieve- ment gap between rural and urban schools.
