The current educational technologies in developing countries are not always successfully implemented and utilized due to infrastructure limitations, such as limited resources, limited training in educational technologies, and the unrealized potential usefulness of these technologies. Using an effective and relevant educational technology will efficiently maximize the use of the limited resources available to schools in developing countries in order to provide a larger outreach and increase access to up-to-date information and useful electronic resources. Thus, the authors propose TrimCloud as an alternative educational technology to help rebuild the education system and encourage innovation and development in developing countries. TrimCloud is an open-source virtual desktop infrastructure (VDI) that is offered as a software-as-a-service (SaaS) and a desktop-as-a-service (DaaS). In this paper, the authors examine possible solutions to issues plaguing the educational environment in developing countries by using TrimCloud at the primary, secondary, university/higher education, and administration levels. They propose the use of refurbished legacy systems as the alternative hardware source for using TrimCloud as an educational technology, which will also aid to alleviate the “e-waste dump” problem. Lastly, the authors explore further network enhancements to TrimCloud that will provide a reliable and robust option for developing countries.

Virtual Desktop Infrastructure

With an increasing number of personal computers introduced in schools, enterprises and other large organizations, workloads of system administrators have been on the rise due to the issues related to energy costs, IT expenses, PC replacement expenditures, data storage capacity, and information security, etc. However, Application Virtualization (AV) has been proved as a successful cost-effective solution to solve these problems. In this paper, the analytics of a Virtual Desktop Infrastructure (VDI) system will be taken into consideration for a campus network. Our developed system will be introduced and justified. Furthermore, the rationality for these improvements will be introduced.

PURPOSE International guideline recommendations may not always be extrapolated to developing countries where access to resources is limited. In metastatic castration-sensitive prostate cancer (mCSPC), there have been successful drug and imaging advancements that were addressed in the Prostate Cancer Consensus Conference for Developing Countries for best-practice and limited-resource scenarios. METHODS A total of 24 out of 300 questions addressed staging, treatment, and follow-up for patients with mCSPC both in best-practice settings and resource-limited settings. Responses were compiled and presented in percentage of clinicians supporting each response. Questions had 4-8 options for response. RESULTS Recommendations for staging in mCSPC were split but there was consensus that chest x-ray, abdominal and pelvic computed tomography, and bone scan should be used where resources are limited. In both de novo and relapsed low-volume mCSPC, orchiectomy alone in limited resources was favored and in relapsed high-volume disease, androgen deprivation therapy plus docetaxel in limited resources and androgen deprivation therapy plus abiraterone in high-resource settings were consensus. A 3-weekly regimen of docetaxel was consensus among voters. When using abiraterone, a regimen of 1,000 mg plus prednisone 5 mg/d is optimal, but in limited-resource settings, half the panel agreed that abiraterone 250 mg with fatty foods plus prednisone 5 mg/d is acceptable. The panel recommended against the use of osteoclast-targeted therapy to prevent osseous complications. There was consensus that monitoring of patients undergoing systemic treatment should only be conducted in case of prostate-specific antigen elevation or progression-suggestive symptoms. CONCLUSION The treatment recommendations for most topics addressed differed between the best-practice setting and resource-limited setting, accentuating the need for high-quality evidence that contemplates the effect of limited resources on the management of mCSPC.

PURPOSE To present a summary of the treatment and follow-up recommendations for the biochemical recurrence in castration-sensitive prostate cancer (PCa) acquired through a questionnaire administered to 99 PCa experts from developing countries during the Prostate Cancer Consensus Conference for Developing Countries. METHODS A total of 27 questions were identified as related to this topic from more than 300 questions. The clinician's responses were tallied and presented in a percentage format. Topics included the use of imaging for staging biochemical recurrence, treatment recommendations for three different clinical scenarios, the field of radiation recommended, and follow-up. Each question had 5-7 relevant response options, including “abstain” and/or “unqualified to answer,” and investigated not only recommendations but also if a limitation in resources would change the recommendation. RESULTS For most questions, a clear majority (> 50%) of clinicians agreed on a recommended treatment for imaging, treatment scenarios, and follow-up, although only a few topics reached a consensus > 75%. Limited resources did affect several areas of treatment, although in many cases, they reinforced more stringent criteria for treatment such as prostate-specific antigen values > 0.2 ng/mL and STAMPEDE inclusion criteria as a basis for recommending treatment. CONCLUSION A majority of clinicians working in developing countries with limited resources use similar cutoff points and selection criteria to manage patients treated for biochemically recurrent castration-sensitive PCa.

In this chapter, the author examines the migration process of a legacy system, as a software-as-a-service model, to the Web, and he looks at some of the reasons that drive this legacy system migration. As migration is often a multi-step process, depending on the legacy system being migrated, the author outlines several techniques and transformations for each step of the migration process in order to enable legacy systems, of different types, to be migrated to the cloud. Of particular interest are the different methods to handle data-intensive legacy systems to enable them to function in a cloud computing environment with reduced bandwidth. Unlike the migration of an unstructured legacy system to a locally-distributed desktop system, system migration to a cloud computing environment poses some unique challenges such as restricted bandwidth, scalability, and security. Part of this migration process is adapting the transformed legacy system to be able to function in such an environment. At the end of the chapter, several small case studies of legacy systems, each of a different nature successfully migrated to the cloud, will be given.

The design and development of educational technologies is a complex, interdisciplinary endeavor. Learning science research reveals principles of learning and instruction, and advances in computer science implement these principles in innovative technologies. This chapter promotes a complementary discipline—human systems engineering or “user science”—that emphasizes designing with human users' goals, needs, capabilities, and limitations in mind. Systematic and iterative human systems engineering should contribute to educational technologies that are more functional, usable, desirable, and ultimately more effective. The authors overview key human systems engineering principles (e.g., usability and user experience) and methods (e.g., cognitive task analysis, contextual inquiry, heuristic evaluation, and participatory design), and then consider example applications from research on automated writing evaluation technologies. The chapter concludes with broad research questions posed to researchers, developers, and educators in the field of educational technology.

Problems Of Practice

This chapter describes one science teacher educator’s attempts to integrate various educational technologies in an elementary science methods course, her students’ responses to her attempts, and the tensions that emerged. The science teacher educator employed teacher action research as a means of systematic, reflective inquiry to examine critically how preservice elementary school science teachers think about, use, and reflect on educational technologies and how their developing professional identities intersect with adoption of these technologies. Tensions emerged from a dichotomy between what methods students perceived as “traditional” science teaching and science teaching using technology. Resulting problems of practice included: expertise in/with science and negotiating a new curriculum, control in the classroom, content coverage, and support and sense of community. The authors conclude their chapter with implications and recommendations for future research related to the significant role educational technology can play in science teacher education and science teacher identity development.

Course Management System (CMS) is now probably the most used educational technologies in higher education, behind only the Internet and common office software. It can facilitate posting content, participating in discussions, maintaining a grade book, tracking participation and managing learning activities in an online environment for instructors and learners. But question arises to what extent these systems are successful in developing countries like Bangladesh. Unfortunately there are very few reports and publication that have tried to focus on above issues. In this study, an evaluation and analysis of CMS in developing countries like Bangladesh was carried out to assess the success of the system by using “ITPOSMO' model. The study found that CMS is partially failing in higher educational institutions in Bangladesh.
