How does technical education fit into today's society? What is the implication of the United Nations Decade of Education for Sustainable Development (2005-2014) for technical education? This book examines these questions. The author analyses the corresponding needs within technical education from various perspectives. She has identified different domains within the world of engineering including the domain of engineering profession and practice for manufacturing, design and development of technical solutions to fulfil the consumers' needs, the domain of technology assessment which considers potential impacts of technical solutions on human beings, and the domain of technical education as the foundation for engineering knowledge and skills. This book will be helpful to both researchers and practitioners in shaping the future of technical education.

Security for Pervasive Healthcare

Miniaturization of medical appliances and wireless communication enable the pervasive health monitoring of users in their daily life thus improving users’ health and well-being, helping for quick reaction on emergencies, and yet, allowing for cost reduction in the healthcare sector. In the simplest healthcare setting, a fixed set of wireless medical sensors forms a patient area network (PAN) monitoring the user’s vital signs. Medical staff can access, gather, or process data directly, or transmit it to a remote healthcare service. Pervasive health monitoring in these diverse situations and locations is carried out by different organizations, such as fitness centers or retirement homes, by means of a medical sensor network (MSN) allowing authorized parties to access to the sensed health information.In this context, the exchange of users’ medical data leads to severe privacy and security concerns. Meeting these strict security needs of these ubiquitous medical applications is a big challenge, since privacy of medical data has to be guaranteed all the way from the resource-constrained sensor nodes to the backend services, the system has to fulfill latency needs, and lots of mobility is involved. In fact, ensuring the smooth but secure interaction of the different system parts is one of the most testing tasks.This thesis addresses the challenge of deploying secure medical sensor networks, and to this end we propose algorithms, protocols, and systems that pursue three main goals. The first being the described solutions enabling the efficient deployment of security systems – bearing in mind that the underlying interactions and the expected system operation is fundamental for the successful system deployment. Secondly, the individual mechanisms and the overall architecture should provide a comprehensive solution for key and entity management, access control, and privacy-aware identification. These are the key challenges in the analyzed scenarios due to the pervasive nature of the system wherein a multitude of parties interact with each other. Finally, security methods and cryptographic algorithms should be lightweight to allow for efficient system deployment and operation on resource-constrained devices.Overall, this work proposes a security architecture that is comprised of three security layers, namely MSN, PAN, and backend security layers. In our architecture, the MSN and PAN security layers reflect the trend towards a patient-centric approach wherein both user and health institutions share responsibility on the control of the health information. The MSN security layer is in charge of providing the basic link-security within each MSN. The PAN layer creates a security domain around the user’s PAN giving him control on the disclosure of his health information. The backend security layer ensures smooth interaction between the MSN and PAN layers.The proposed security architecture is articulated and supported by the results in four complementary research areas. The first one refers to lightweight key establishment and information verification algorithms used at the MSN layer. With this we investigate and specify how the wireless medical sensors can agree on pairwise keys and verify information in an efficient way based on polynomial schemes in the scope of an MSN. We propose several optimizations for key establishment algorithms and introduce the concept of lightweight digital certificates that allows for distributed information verification without the need of public-key cryptography.Second, we examine how the polynomial keying material can be distributed and arranged at the MSN security layer to achieve a higher resiliency level, to reduce system requirements, and to provide other security functionalities. We also show how the proposed hierarchical and multidimensional systems – tailored to fit the underlying organization of health institutions – allow for efficient deployment. A resourceful approach for key establishment is not usable if it cannot be deployed and managed, hence, we describe two key distribution and management systems for the polynomial keying material fitting the specific system deployment and operational requirements. The first system, which applies to infrastructureless systems, relies on a lightweight but resilient device, a smart card, playing the role of trust center. The second one makes use of backend services to control and manage more complex systems comprised of a multitude of networks.Third, we introduce several lightweight security mechanisms running at the PAN security layer. We describe the system interactions between both the MSN and PAN layers based on dedicated-hardware including the formation and management of the PAN security domain within the MSN security domain. The main goal of this piece of hardware, the patient security manager star – that consists of a healthcare card linked to each user and a patient security manager managed by the MSN – is to allow for PAN roaming between MSNs while guaranteeing end-to-end security. Additionally, this layer provides user privacy-aware identification for roaming users based on a hierarchy of identifiers and context-aware access control depending, e.g., on the user’s health state.The fourth addressed research topic is denominated cooperative security, an approach that aims at leveraging system security by enforcing cooperation among the nodes in an MSN, converting PANs in authentic distributed security domains that are able to manage their trust relationships, and allowing for fast and distributed revocation when nodes misbehave thus enhancing the system security.After successfully analyzing, prototyping, and testing the key components in both the MSN and the PAN layers, we have shown that our comprehensive security architecture and its components can play a fundamental role in the efficient and progressive rollout of secure pervasive healthcare systems. Further research lines emerge from this work. The first one refers to the additional refinements and extensions of the overall security architecture as well as a closer analysis of the interactions between PAN and MSN in specific use cases. The second one refers to the design of identity-based pairwise key generation engines based on non-linear keying material structures that can allow any pair of peers to generate a common symmetric-key given their identifiers but without suffering from the alpha-secure property inherent to the polynomial schemes. Such schemes might become more and more important for future pervasive systems comprising thousands or millions of devices. The third one involves further extensions for cooperative security protocols to convert large-scale distributed systems into living networks capable of autonomously controlling their own security system and removing infected nodes.

The Leadership Capital Index: Realizing the Mar...

When it comes to evaluating a firm, leadership matters. We know that financial outcomes can predict about 50 percent of a firm's market value. Intangibles like strategy, brand, talent, R&D, innovation, risk, and so on account for the rest. But leadership underlies them all. And despite how important we know it is, we've been forced to rely on subjective and unreliable ways to measure its impact - until now. In this landmark book, leadership scholar, author, and consultant Dave Ulrich proposes a 'leadership capital index' - a Moody's or Standard and Poor's rating for leadership. Drawing on research from investors and business leaders, and synthesizing the work of dozens of consulting firms and leadership experts, Ulrich analyzes two broad domains, each comprising five factors. The individual domain includes personal qualities, strategic prowess, execution proficiency, interpersonal skills, and fit between the leader's style and the organization's market promises. The organizational domain encompasses a leader's ability to create customer-focused cultures, manage talent, demand accountability, use information to gain competitive advantage, and set up work processes to deal with change. Ulrich details rigorous metrics and methods for evaluating leaders on each of these factors. The result is a groundbreaking book that will be of vital interest not only to equity and debt investors but also to boards of directors, executive teams, human resource and leadership development professionals, government and ratings agencies - and of course to leaders themselves.

Handbook of Item Response Theory Modeling
234,00 CHF *
ggf. zzgl. Versand

Item response theory (IRT) has moved beyond the confines of educational measurement into assessment domains such as personality, psychopathology, and patient-reported outcomes. Classic and emerging IRT methods and applications that are revolutionizing psychological measurement, particularly for health assessments used to demonstrate treatment effectiveness, are reviewed in this new volume. World renowned contributors present the latest research and methodologies about these models along with their applications and related challenges. Examples using real data, some from NIH-PROMIS, show how to apply these models in actual research situations. Chapters review fundamental issues of IRT, modern estimation methods, testing assumptions, evaluating fit, item banking, scoring in multidimensional models, and advanced IRT methods. New multidimensional models are provided along with suggestions for deciding among the family of IRT models available. Each chapter provides an introduction, describes state-of-the art research methods, demonstrates an application, and provides a summary. The book addresses the most critical IRT conceptual and statistical issues confronting researchers and advanced students in psychology, education, and medicine today. Although the chapters highlight health outcomes data the issues addressed are relevant to any content domain. The book addresses: IRT models applied to non-educational data especially patient reported outcomes Differences between cognitive and non-cognitive constructs and the challenges these bring to modeling. The application of multidimensional IRT models designed to capture typical performance data. Cutting-edge methods for deriving a single latent dimension from multidimensional data A new model designed for the measurement of constructs that are defined on one end of a continuum such as substance abuse Scoring individuals under different multidimensional IRT models and item banking for patient-reported health outcomes How to evaluate measurement invariance, diagnose problems with response categories, and assess growth and change. Part 1 reviews fundamental topics such as assumption testing, parameter estimation, and the assessment of model and person fit. New, emerging, and classic IRT models including modeling multidimensional data and the use of new IRT models in typical performance measurement contexts are examined in Part 2. Part 3 reviews the major applications of IRT models such as scoring, item banking for patient-reported health outcomes, evaluating measurement invariance, linking scales to a common metric, and measuring growth and change. The book concludes with a look at future IRT applications in health outcomes measurement. The book summarizes the latest advances and critiques foundational topics such a multidimensionality, assessment of fit, handling non-normality, as well as applied topics such as differential item functioning and multidimensional linking. Intended for researchers, advanced students, and practitioners in psychology, education, and medicine interested in applying IRT methods, this book also serves as a text in advanced graduate courses on IRT or measurement. Familiarity with factor analysis, latent variables, IRT, and basic measurement theory is assumed.

How well do our assumptions about the global challenges of energy, environment and economic development fit the facts? Energy prices have varied hugely between countries and over time, yet the share of national income spent on energy has remained surprisingly constant. The foundational theories of economic growth account for only about half the growth observed in practice. Despite escalating warnings for more than two decades about the planetary risks of rising greenhouse gas emissions, most governments have seemed powerless to change course. Planetary Economics shows the surprising links between these seemingly unconnected facts. It argues that tackling the energy and environmental problems of the 21st Century requires three different domains of decision-making to be recognised and connected. Each domain involves different theoretical foundations, draws on different areas of evidence, and implies different policies. The book shows that the transformation of energy systems involves all three domains - and each is equally important. From them flow three pillars of policy - three quite distinct kinds of actions that need to be taken, which rest on fundamentally different principles. Any pillar on its own will fail. Only by understanding all three, and fitting them together, do we have any hope of changing course. And if we do, the oft-assumed conflict between economy and the environment dissolves - with potential for benefits to both. Planetary Economics charts how.
