In 2006, the University of Alaska Anchorage (UAA) upgraded the telephone system at its main campus in Anchorage from a traditional private branch exchange (PBX) architecture to a Voice over Internet Protocol (VoIP) system. This case describes the organizational decisions that led to the change; the scope and the process of upgrading; and the current status of the new VoIP system. The actual migration to VoIP was completed less than a year after the start of the project. The transition process went smoothly. User satisfaction with the performance of the VoIP system is very high. Based on extensive interviews with decision makers and the technical personnel involved, this case also describes financial considerations (including “creative” ways to stretch a limited budget), outsourcing considerations, training related issues, as well as lessons learned.

The Mars Regional Atmospheric Modeling System (MRAMS) is closing in on two decades of use as a tool to investigate mesoscale and microscale circulations and dynamics in the atmosphere of Mars. Over this period of time, there have been numerous improvements and additions to the model dynamical core, physical parameterizations, and framework. At the same time, the application of the model to Mars (and related code for other planets) has taught many lessons about limitations and cautions that should be exercised. The current state of MRAMS is described along with a review of prior studies and findings utilizing the model. Where appropriate, lessons learned are provided to help guide future users and aid in the design and interpretation of numerical experiments. The paper concludes with a discussion of future MRAMS development plans.

Small island developing states (SIDS) are typically characterized by being environmentally and socio-economically vulnerable to disasters and climate change. Additionally, they often have limited resources for freshwater provisioning services. This article presents an assessment of disaster risk and water security-related challenges in SIDS focusing on three major dimensions: (a) how disaster risks are perceived and addressed in the SIDS context using a case study method, (b) analyzing the current status of water security in these regions using an indicator-based approach and (c) assessing gaps and needs in institutions and policies that can facilitate sustainable development goals (SDGs) and targets, adaptation and resilience building in SIDS. In this regard, information on all SIDS is collected to be able to distinguish trends in and between SIDS based on amongst others geographical location and characteristics. This synthesis noted two key observations: first, that in SIDS, the number of disasters is increasing at a higher rate than the global average, and that the frequency and intensity of the disasters will likely increase because of climate change. These combined factors will impact SIDS on the societal level and on environmental levels, reducing their adaptive capacity, resources, and resilience. Second, most SIDS are already water-scarce with low groundwater volumes. Because of increasing demand (e.g., population growth and tourism) and decreasing supply (e.g., pollution and changes in precipitation patterns) freshwater resources are becoming increasingly limited, often suffering from the spillover effects of competing and conflicting uses. Threatened ecosystems and limited economic resources further influence the adaptive capacities of communities in SIDS. In this light, key solutions to address disaster-risk and water security-related challenges can be found by sharing best practices and lessons learned—from examples of good governance, integrated policies, improved community-resilience, and capacity-building. Added to their fragile situation, SIDS struggle to find enough funding to put their development plans, programs, and policies into action.

Abstract The API 20S Standard is designed to play a crucial role in leveraging Additive Manufacturing (AM) to foster innovation in the oil and gas industry. The paper, in association with the standard, will facilitate the understanding of how AM will enable equipment design improvements, faster prototyping, and better inventory management. By way of discussing the progress, challenges, and lessons learned from the standardization process, the paper aims to encourage a safer, broader, and faster adoption of AM technologies in the mainstream oil and gas applications. The paper will summarize the streamlining process, feedback from the API 20S task group, and current status of the standardization efforts. Additionally, upcoming challenges and the potential for the oil and gas industry industries to contribute to the standard will be summarized. The paper will also showcase a novel tiered approach (Additive Manufacturing Specification Levels) to allow the users of the document to match different levels of criticality.

Various endovascular intraarterial approaches are available for treating patients with acute ischemic stroke who present with severe neurological deficits. Three recent randomized trials—Interventional Management of Stroke (IMS) III, Mechanical Retrieval and Recanalization of Stroke Clots Using Embolectomy (MR RESCUE), and Synthesis Expansion: A Randomized Controlled Trial on Intra-Arterial Versus Intravenous Thrombolysis in Acute Ischemic Stroke (SYNTHESIS Expansion)—evaluated the efficacy of endovascular treatment of acute ischemic stroke and, after failing to demonstrate any significant clinical benefit of endovascular therapies, raised concerns and questions in the medical community regarding the future of endovascular treatment for acute ischemic stroke. In this paper, the authors review the evolution of endovascular treatment strategies for the treatment of acute stroke and provide their interpretation of findings and potential limitations of the three recently published randomized trials. The authors discuss the advantage of stent-retriever technology over earlier endovascular approaches and review the current status and future directions of endovascular acute stroke studies based on lessons learned from previous trials.

Endoscopic examination and pleuridirectional polytomography provided some important insights into the pathogenesis of inflammatory sinus disease. These insights have been further refined by the increasing utilization of endoscopy in medical therapy and surgical follow-up, and by the use of computed tomography for diagnosis. The aim of this paper is to review the current status of the diagnosis of chronic inflammatory sinus disease and of functional endoscopic surgical techniques. The impact of this approach on previously held theoretical and diagnostic concepts is evaluated. Technical modifications made since the surgery was first introduced in the United States and the lessons learned from close postsurgical endoscopic examination are presented.

ABSTRACTThe reliability of silicon integrated circuits (ICs) has improved significantly in the last decade. The complexity of ICs continues to increase. The semiconductor industry is actively working to a) improve the reliability of very large scale (VLSI) ICs, and b) reduce the failure rates to a value closer to 0.1 FIT by the year 2000. This paper summarizes the current status of quality and reliability of ICs. Some of the reliability limiting factors are described. Inadequacy of conventional accelerated test methods to verify the reliability of VLSI devices is highlighted. A challenging VLSI reliability goal with a failure rate approaching 0.1 FIT requires a) an understanding of the root causes of failure mechanisms, b) a translation of the lessons learned into a set of design rules for the circuit designers, c) appropriate materials and process specifications consistent with manufacturing capabilities, and d) in-process reliability test structures and test procedures. A VLSI failure rate goal of 0.1 FIT presents an exciting challenge for the materials scientists.

The transition from mass higher education to universal access globally marked by the creation of a series of higher education institutions (HEIs) has pushed countries to undergo reforms, rearrangement of higher education system. The wave of merger, consolidation, or alliance between HEIs may stem from the need of the schools themselves who gave proposal or from the administrative orders of the administrative authorities to fulfill the policy objectives. Countries in the world have continued the process of reforming and reorganizing the higher education system and have achieved certain successes and inevitably some mistakes. These are valuable lessons for the following countries. This paper is aimed at showing the experience of nations and some lessons learned. It is composed of four parts. The first part gives an overview of the current global higher eduction reform, the definition of concepts used herein and distinguishes some types of mergers, consolidations and alliances in terms of the number and the status of founding institutions. The second part analyzes the results of the process such as changes in system size, student size, performance, impacts on stakeholders after the merger. The third part summarizes the current status of Vietnamese higher education with outstanding issues which required the reorganization and the reform of the system for the purpose of enhancing efficiency and regional and global competitiveness. In the final section, the paper provides some recommendations for Vietnamese higher education, which were drawn from the successes and failures of the process of reforming higher education systems around the world.
