    A crisis continues to brew within the pharmaceutical research and development (R&D) enterprise: productivity continues declining as costs rise, despite ongoing, often dramatic scientific and technical advances. To reverse this trend, we offer various suggestions for both the expansion and broader adoption of modeling and simulation (M&S) methods. We suggest strategies and scenarios intended to enable new M&S use cases that directly engage R&D knowledge generation and build actionable mechanistic insight, thereby opening the door to enhanced productivity. What M&S requirements must be satisfied to access and open the door, and begin reversing the productivity decline? Can current methods and tools fulfill the requirements, or are new methods necessary? We draw on the relevant, recent literature to provide and explore answers. In so doing, we identify essential, key roles for agent-based and other methods. We assemble a list of requirements necessary for M&S to meet the diverse needs distilled from a collection of research, review, and opinion articles. We argue that to realize its full potential, M&S should be actualized within a larger information technology framework--a dynamic knowledge repository--wherein models of various types execute, evolve, and increase in accuracy over time. We offer some details of the issues that must be addressed for such a repository to accrue the capabilities needed to reverse the productivity decline

    Agile Requirements Engineering: A systematic literature review

    Nowadays, Agile Software Development (ASD) is used to cope with increasing complexity in system development. Hybrid development models, with the integration of User-Centered Design (UCD), are applied with the aim to deliver competitive products with a suitable User Experience (UX). Therefore, stakeholder and user involvement during Requirements Engineering (RE) are essential in order to establish a collaborative environment with constant feedback loops. The aim of this study is to capture the current state of the art of the literature related to Agile RE with focus on stakeholder and user involvement. In particular, we investigate what approaches exist to involve stakeholder in the process, which methodologies are commonly used to present the user perspective and how requirements management is been carried out. We conduct a Systematic Literature Review (SLR) with an extensive quality assessment of the included studies. We identified 27 relevant papers. After analyzing them in detail, we derive deep insights to the following aspects of Agile RE: stakeholder and user involvement, data gathering, user perspective, integrated methodologies, shared understanding, artifacts, documentation and Non-Functional Requirements (NFR). Agile RE is a complex research field with cross-functional influences. This study will contribute to the software development body of knowledge by assessing the involvement of stakeholder and user in Agile RE, providing methodologies that make ASD more human-centric and giving an overview of requirements management in ASD.Ministerio de EconomĂ­a y Competitividad TIN2013-46928-C3-3-RMinisterio de EconomĂ­a y Competitividad TIN2015-71938-RED

    Teacher Candidates’ Perceptions of the Integration of Faith and Learning as Christian Vocation

    The overriding purpose of Christian liberal arts colleges in the United States is to offer a comprehensive education to their students. Inherent in this goal is the deliberate integration of Christian faith with academic content; it is, after all, what differentiates Christian institutions of higher education from their secular counterparts (Muntz & Crabtree, 2006). The mission statement of Trinity International University (TIU) in Deerfield, Illinois is to “educate men and women for faithful participation in God’s redemptive work in the world by cultivating academic excellence, Christian fidelity and lifelong learning.” The Division of Education that prepares candidates for certification to teach in K-12 schools in the state of Illinois defines its more specific mission thusly: “to develop highly qualified Christian teachers who view teaching as a mission; they nurture their students, reflect critically on their practice, and facilitate classroom experience to maximize the potential of all learners.” Implicit in this conceptual framework is that faculty members will engage in their own integration of faith and learning so that they can model what it means to be Christian teachers. In February 2009, as professors in TIU’s Division of Education, we informally surveyed a group of traditional undergraduate education majors during a department chapel session to discover their perceptions about the integration of faith and learning within our department. We were curious to find out whether or not what we believed we were doing in our classes regarding the integration of faith and learning was in fact impacting our teacher candidates. After defining the concept of the integration of faith and learning in broad terms, we asked them what has helped them become “highly qualified Christian teachers” within our education program. Their responses primarily focused on the more external aspects of demonstrating personal faith; i.e., professors’ leading in devotions at the beginning of classes and modeling Christian behaviors and attitudes. Admittedly, we were somewhat disappointed with their answers, concluding that our teacher candidates were not viewing integration as an academic endeavor that requires deep intellectual as well as spiritual analysis (Hasker, 1992). This concern led to a desire to explore their perceptions further in a more formal way, leading us to review the literature on the integration of faith and learning in Christian colleges and universities and to conduct this particular research study

    Contours of Inclusion: Inclusive Arts Teaching and Learning

    The purpose of this publication is to share models and case examples of the process of inclusive arts curriculum design and evaluation. The first section explains the conceptual and curriculum frameworks that were used in the analysis and generation of the featured case studies (i.e. Understanding by Design, Differentiated Instruction, and Universal Design for Learning). Data for the cases studies was collected from three urban sites (i.e. Los Angeles, San Francisco, and Boston) and included participant observations, student and teacher interviews, curriculum documentation, digital documentation of student learning, and transcripts from discussion forum and teleconference discussions from a professional learning community.The initial case studies by Glass and Barnum use the curricular frameworks to analyze and understand what inclusive practices look like in two case studies of arts-in-education programs that included students with disabilities. The second set of precedent case studies by Kronenberg and Blair, and Jenkins and Agois Hurel uses the frameworks to explain their process of including students by providing flexible arts learning options to support student learning of content standards. Both sets of case studies illuminate curricular design decisions and instructional strategies that supported the active engagement and learning of students with disabilities in educational settings shared with their peers. The second set of cases also illustrate the reflective process of using frameworks like Universal Design for Learning (UDL) to guide curricular design, responsive instructional differentiation, and the use of the arts as a rich, meaningful, and engaging option to support learning. Appended are curriculum design and evaluation tools. (Individual chapters contain references.

    Climate Science, Development Practice, and Policy Interactions in Dryland Agroecological Systems

    The literature on drought, livelihoods, and poverty suggests that dryland residents are especially vulnerable to climate change. However, assessing this vulnerability and sharing lessons between dryland communities on how to reduce vulnerability has proven difficult because of multiple definitions of vulnerability, complexities in quantification, and the temporal and spatial variability inherent in dryland agroecological systems. In this closing editorial, we review how we have addressed these challenges through a series of structured, multiscale, and interdisciplinary vulnerability assessment case studies from drylands in West Africa, southern Africa, Mediterranean Europe, Asia, and Latin America. These case studies adopt a common vulnerability framework but employ different approaches to measuring and assessing vulnerability. By comparing methods and results across these cases, we draw out the following key lessons: (1) Our studies show the utility of using consistent conceptual frameworks for vulnerability assessments even when quite different methodological approaches are taken; (2) Utilizing narratives and scenarios to capture the dynamics of dryland agroecological systems shows that vulnerability to climate change may depend more on access to financial, political, and institutional assets than to exposure to environmental change; (3) Our analysis shows that although the results of quantitative models seem authoritative, they may be treated too literally as predictions of the future by policy makers looking for evidence to support different strategies. In conclusion, we acknowledge there is a healthy tension between bottom-up/ qualitative/place-based approaches and top-down/quantitative/generalizable approaches, and we encourage researchers from different disciplines with different disciplinary languages, to talk, collaborate, and engage effectively with each other and with stakeholders at all levels
