ICOPER Project - Deliverable 4.3 ISURE: Recommendations for extending effective reuse, embodied in the ICOPER CD&R

The purpose of this document is to capture the ideas and recommendations, within and beyond the ICOPER community, concerning the reuse of learning content, including appropriate methodologies as well as established strategies for remixing and repurposing reusable resources. The overall remit of this work focuses on describing the key issues that are related to extending effective reuse embodied in such materials. The objective of this investigation, is to support the reuse of learning content whilst considering how it could be originally created and then adapted with that ‘reuse’ in mind. In these circumstances a survey on effective reuse best practices can often provide an insight into the main challenges and benefits involved in the process of creating, remixing and repurposing what we are now designating as Reusable Learning Content (RLC). Several key issues are analysed in this report: Recommendations for extending effective reuse, building upon those described in the previous related deliverables 4.1 Content Development Methodologies and 4.2 Quality Control and Web 2.0 technologies. The findings of this current survey, however, provide further recommendations and strategies for using and developing this reusable learning content. In the spirit of ‘reuse’, this work also aims to serve as a foundation for the many different stakeholders and users within, and beyond, the ICOPER community who are interested in reusing learning resources. This report analyses a variety of information. Evidence has been gathered from a qualitative survey that has focused on the technical and pedagogical recommendations suggested by a Special Interest Group (SIG) on the most innovative practices with respect to new media content authors (for content authoring or modification) and course designers (for unit creation). This extended community includes a wider collection of OER specialists. This collected evidence, in the form of video and audio interviews, has also been represented as multimedia assets potentially helpful for learning and useful as learning content in the New Media Space (See section 4 for further details). Section 2 of this report introduces the concept of reusable learning content and reusability. Section 3 discusses an application created by the ICOPER community to enhance the opportunities for developing reusable content. Section 4 of this report provides an overview of the methodology used for the qualitative survey. Section 5 presents a summary of thematic findings. Section 6 highlights a list of recommendations for effective reuse of educational content, which were derived from thematic analysis described in Appendix A. Finally, section 7 summarises the key outcomes of this work

Reduce, Reuse, and Recycle: A Summary of Dissertation Recitals

Three dissertation recitals were performed in partial fulfillment of the requirements for the degree of Doctor of Musical Arts (Music: Conducting) in the University of Michigan. The repertoire performed on these recitals traverses the major time periods and styles of Western art music and each of the composers presented have reduced, reused, or recycled material from musical and extra-musical sources to create highly innovative and important compositions for wind band. The first recital was a compilation of performances with various concert and chamber ensembles at the University of Michigan during the 2016-2017 school year. This recital included Robert Beaser’s Manhattan Roll; selections from Mozart’s Le nozze di Figaro arranged for harmonie by Johann Wendt; a revised edition of Florent Schmitt’s Turkish dance, Selamlik, by Stephen Meyer; Chant Funéraire by Gabriel Fauré; and Emil Hartmann’s Serenade, Op. 43. The second recital consisted of Gustav Holst’s arrangement of Bach’s Organ Fugue in G Major [BWV 577] in Bach’s Fugue á la Gigue; Alfred Reed’s setting of Bach’s Komm, süsser Tod; a set of three pieces by Percy Grainger that included Children’s March: Over the Hills and Far Away, Colonial Song, and Shepherd’s Hey; Norman Dello Joio’s Variants on a Medieval Tune; and Steven Bryant’s Ecstatic Waters. Performances of these works occurred on two different concerts with the Crane Wind Ensemble at the Crane School of Music-State University of New York Potsdam, during the fall of 2017. The Crane Wind Ensemble also presented the third dissertation recital on November 20, 2017. This performance included Joel Puckett’s Ping, Pang, Pong; Jan Pieterszoon Sweelinck’s Variations on Mein junges Leben hat ein End arranged for wind ensemble by Ramon Ricker; Omar Thomas’ Of Our New Day Begun; and Symphonic Metamorphosis of Themes by Carl Maria von Weber by Paul Hindemith, transcribed by Keith Wilson.AMUMusic: ConductingUniversity of Michigan, Horace H.

SOFTWARE REUSE: SURVEY AND RESEARCH DIRECTIONS

Software reuse is the use of software resources from all stages of the software development process in new applications. Given the high cost and difficulty of developing high quality software, the idea of capitalizing on previous software investments is appealing. However, software reuse has not been as effective as expected and has not been very broadly or systematically used in industry. This paper surveys recent software reuse research using a framework that helps identify and organize the many factors that must be considered to achieve the benefits of software reuse in practice. We argue that software reuse needs to be viewed in the context of a total systems approach that addresses a broad range of technical, economic, managerial, organizational and legal issues and conclude with a summary of the major research issues in each of these areas.Information Systems Working Papers Serie

Earth Observatory Satellite (EOS) system definition study

An executive summary of a study on the Earth Observatory Satellite (EOS) was presented. It was concluded that the overall costs of space systems could be reduced significantly by the development of a modular shuttle compatible standard spacecraft, and the use of that spacecraft with the Shuttle Transportation System. It was also demonstrated that the development of the standard spacecraft is feasible, desirable, and cost effective if applied to a series of missions. The ability to initially retrieve, refurbish, and reuse the spacecraft and its payload, and ultimately to perform in-orbit servicing, would result in significant cost savings. A number of specific conclusions and recommendations were also suggested

The development of a resource-efficient photovoltaic system

This paper presents the measures taken in the demonstration of the photovoltaic case study developed within the European project ‘Towards zero waste in industrial networks’ (Zerowin), integrating the D4R (Design for recycling, repair, refurbishment and reuse) criteria at both system and industrial network level. The demonstration is divided into three phases. The first phase concerns the development of a D4R photovoltaic concept, the second phase focused on the development of a specific component of photovoltaic systems and the third phase was the demonstration of the D4R design in two complete photovoltaic systems (grid-connected and stand-alone). This paper includes a description of the installed photovoltaic systems, including a brief summary at component level of the lithium ion battery system and the D4R power conditioning system developed for the pilot installations. Additionally, industrial symbioses within the network associated with the photovoltaic systems and the production model for the network are described

A review of polymeric membranes and processes for potable water reuse

Conventional water resources in many regions are insufficient to meet the water needs of growing populations, thus reuse is gaining acceptance as a method of water supply augmentation. Recent advancements in membrane technology have allowed for the reclamation of municipal wastewater for the production of drinking water, i.e., potable reuse. Although public perception can be a challenge, potable reuse is often the least energy-intensive method of providing additional drinking water to water stressed regions. A variety of membranes have been developed that can remove water contaminants ranging from particles and pathogens to dissolved organic compounds and salts. Typically, potable reuse treatment plants use polymeric membranes for microfiltration or ultrafiltration in conjunction with reverse osmosis and, in some cases, nanofiltration. Membrane properties, including pore size, wettability, surface charge, roughness, thermal resistance, chemical stability, permeability, thickness and mechanical strength, vary between membranes and applications. Advancements in membrane technology including new membrane materials, coatings, and manufacturing methods, as well as emerging membrane processes such as membrane bioreactors, electrodialysis, and forward osmosis have been developed to improve selectivity, energy consumption, fouling resistance, and/or capital cost. The purpose of this review is to provide a comprehensive summary of the role of polymeric membranes and process components in the treatment of wastewater to potable water quality and to highlight recent advancements and needs in separation processes. Beyond membranes themselves, this review covers the background and history of potable reuse, and commonly used potable reuse process chains, pretreatment steps, and advanced oxidation processes. Key trends in membrane technology include novel configurations, materials, and fouling prevention techniques. Challenges still facing membrane-based potable reuse applications, including chemical and biological contaminant removal, membrane fouling, and public perception, are highlighted as areas in need of further research and development.

Literature review on appropriate health-based standards for direct and indirect potable reuse as well as various non-potable reuse scenarios

Project Summary Objectives: Water reuse is an increasingly important response to water stress; however, major advancements in water reuse have neglected small, rural communities that comprise most public water systems. The objective of this project is to accelerate water reuse adoption in rural communities by increasing technical and community readiness. The general hypothesis is that community readiness for water reuse in small systems can be accelerated by a convergence of technical, informational, social, and institutional innovation. Also, we hypothesize that severe water scarcity need not be a prerequisite for water reuse implementation, given careful attention to windows of opportunity that integrate multiple community concerns. Approach: Barriers to water reuse adoption are intertwined and complex. Therefore, our proposed work will be an integrated research and engagement program in which we: (1) address knowledge gaps and generate frameworks for overcoming these barriers, and (2) use research outputs to evaluate and accelerate community readiness for reuse in five case studies. Both general activities will be executed in parallel such that knowledge can be co-produced with decision-makers. Specific methods to address knowledge gaps include community surveys, the use of a prototype calculation engine, and desktop, bench-scale and pilot-scale evaluations of treatment technologies. Specific methods to accelerate community readiness include legal and policy analyses and case-study evaluations of five small water systems. Expected Results: This project is expected to produce outputs and outcomes that lead to acceleration of community readiness for reuse in small systems. Specifically, key results include modular, decision support tools such as water inventories, technology databases, and cost and demand curves for reuse. These outputs will be integrated into institutional and regulatory decision-making processes in small, rural, underserved communities with results made available to communities through workshops, outreach events, and publications. We will go through many iterative processes throughout the project in which feedback from small community members and stakeholders will inform the modifications of tools and outputs so that they are indeed meaningful and useful to small communities facing unique challenges

Institutional arrangements for resource recovery and reuse in the wastewater sector

As populations grow and urban centres expand, meeting water demand and wastewater management requirements will become increasingly difficult. Goal 6 of the Sustainable Development Goals is to: ‘Ensure availability and sustainable management of water and sanitation for all’. Part of the approach to achieving this will be reusing wastewater and will require a greater understanding of the institutional arrangements that support or obstruct reuse. This research was designed to achieve this and aimed to develop a set of factors that investors could use to assess the institutional feasibility of reuse in a given setting. The methodology combined a case study approach, focusing on wastewater systems in Bangalore, India and Hanoi, Vietnam, with triangle analysis to assess: the content of policies and laws; the structures (formal and informal) to implement laws and reuse projects; and the culture around acceptance and engagement in reuse. The reuse practices observed in Bangalore were treatment and use within apartments, centralized treatment and sale to industries, use in agriculture after natural attenuation, groundwater recharge and lake regeneration. In Hanoi the only reuse was indirect use from rivers feeding fish ponds and fields, although formal treatment and use is planned. Critically, both cities have environmental and water resources policies and laws that advocate reuse, as well as related local legislation. However, support for reuse is not reciprocated in industrial, agricultural or fisheries law, the result being that reuse does not always take place as planned. Legislation is required along the whole sanitation chain to the point of wastewater use. Structures to implement reuse are also vital. In Bangalore the water board has initiated reuse projects and established the New Initiatives Division but resources are a limiting factor. Effective institutions include expertise, manpower and financing mechanisms, which are lacking in both cities. The environment agency is also engaged in reuse though legislation on recycling in residential and commercial complexes but guidance for users is inadequate, expectations are perceived to be excessive and monitoring is almost impossible. The driver for reuse is increasingly the benefits observed by users. In the case of apartments this is a reliable water source and reduced costs of water supply. As a result, a private sector in wastewater treatment is becoming established. The active civil society and strong, independent media are instrumental in providing information to potential users and holding authorities to account in Bangalore. Their absence in Hanoi is notable. In summary, institutional elements to be considered are: supportive legislation across all sectors; details of acceptable reuse, deterrents and inducements; budget allocation; structures to enable reuse; strong civil society, NGOs, courts, media and universities providing evidence of suitability and safety; donors and finance mechanisms; and stakeholders willing to use the products. Encumbrances are inconsistent or uncoordinated legislation, lack of cooperation and insufficient benefit sharing or perceptions of benefits along the reuse chain
