Full textAbstract:
To solve trajectory tracking problem of switched system with sensor saturation, an iterative learning control algorithm is proposed. The method uses actual measurement error to modify the control variable of system on the premise that switched rule does not change along iteration axis, but it randomly changes along time axis. Moreover, by dealing with the saturation via diagonal matrix method, the convergence of the algorithm is strictly proved in the sense of λ-norm, and the convergence condition is derived. The algorithm can achieve complete tracking of desired trajectory in the finite time interval under the random switched rule, as iterations increase. The simulation example verifies the validity of the proposed algorithm.

Full textAbstract:
Iterative learning control (ILC) requires that the operating conditions of the controlled system must remain unchanged in the repetitive learning process. If the parameters of system change, the former control experience of ILC would not be effective anymore. A new process of iterative learning has to restart, which will exhaust more time and resource. Compared with learning from zero experience, appropriate initial data for the first iteration could reduce the turns of iterations to achieve the target tracking accuracy. When the parameters of a linear system change, its structure and nature are still intrinsically related to the original system. So, if the experience obtained from original ILC could be correspondingly adjusted according to the difference of new and original system, and use the adjusted experience as the initial data in the new iterative learning process, it would reduce the time and save the resource in the new ILC. Based on the idea of experience inheritance and transform, an experience transfer approach for the initial data of ILC is proposed in reference to the relation between the new and original systems. In this paper, via the method of recombining, translational and amplitude adjusting, the experience of former ILC is transferred as the initial control data of new ILC. Simulation shows that the convergence iteration of ILC with experience transfer approach reduces 55–75%, which demonstrates the effectiveness and advantages of the approach proposed in this paper. Both the deviation of the first iteration in ILC and the turns of iterations for achieving desired accuracy are reduced greatly.

Parallel asynchronous iterative algorithms exhibit features that are extremely well-suited for Grid computing, such as lack of synchronization points. Unfortunately, they also suffer from slow convergence rates. In this paper we propose using asynchronous methods as a coarse-grained preconditioner in a flexible iterative method, where the preconditioner is allowed to change in each iteration step. A full implementation of the algorithm is presented using Grid middleware that allows for both synchronous and asynchronous communication. Advantages and disadvantages of the approach are discussed. Numerical experiments on heterogeneous computing hardware demonstrate the effectiveness of the proposed algorithm on Grid computers, with application to large 2D and 3D bubbly flow problems.

We describe LearnIT, a computer program that can observe an iterative solution to a parametric design problem and learn the design strategy employed. When the design requirements change, the program uses the learned strategy to automatically generate a new solution in the “style” of the original. The program uses a specialized instance-based learning method based on the observation that iterative design is often a form of debugging—each iteration is an attempt to repair a particular flaw in the design. Thus, the program learns the design strategy by observing what actions are taken in response to each kind of flaw. [S1050-0472(00)01203-4]

Full textAbstract:
Internet-based electronic commerce is a rapidly evolving phenomenon. Organisations have reacted to the opportunities that have been presented through electronic commerce as new class of strategic information system that can be defined as an Internet Protocol Based Information System (IPBIS). As the demand for IPBIS grows, organisations are looking for ways to use it in order to leverage strategic advantage within their given markets. However, IPBIS are not yet established, and there are many unknowns surrounding its use and the change effects it may have on adopting organisations. Research is emerging that answers some of the organisational and electronic market issues that are being posed by organisations, but which are not being addressed by the increasing amounts of non-academic hyperbole that is in evidence. This study was conducted using a mixed mode of case study research within a grounded theory framework to explore the role of IPBIS as a contributing factor to organisational change. Twelve cases were studied using semi-structure interviews and observation, to assess technology implementation strategies, change effects, and management of change strategies. This study has revealed that organisations follow a staged model of integration that may start as a tentative venture with simple email facilities, and then moves through a set of discreet stages to potential full integration with internal information systems, which may be outsourced to third party solution providers. Evidence supports a substantive theory of 'Push-Pull Decision Taking' that was developed to provide an explanatory framework showing that organisations reach a stage of risk analysis and information elicited, and then feel compelled to participate in IPBIS electronic commerce initiatives, which are not always in the immediate interests of the organisation. The results of this decision taking are that the organisation and its actors try to develop appropriate management strategies, which typically support incremental change. This resulting model of change and a series of working propositions provide a basis for practitioner work, and further academic research in this domain.

Full textAbstract:
Background: There is an increasing amount of arguments made that new business models are the solution when companies and industries face radical changes in the environment. To be able to prosper in the long run, organizations must reinvent themselves over and over again. Many authors (e.g. Abernathy & Utterback, 1978; Christensen, 1997; Kim & Mauborgne, 2005; Ries, 2011) claim that big, radical, reconfigurations are needed in order to prosper in the long-term. Theories, concepts and framework have been developed to answer how this reconfiguration should happen within organizations. However, the concepts derived are just parts of the solution, and none take a holistic approach, trying to cover them in a practical framework that could be used by organizations. Aim: The aim of the thesis is to propose a framework that enables organizations to systemize their innovation processes, making them flexible enough to repetitively seize opportunities through business model innovation where new value can be created and captured. The proposed framework aims to enable organizations to start discussing how they should create and capture new value and give them a more pragmatic view on the innovation process. It also aims to act as a starting point for future research. Methodology: The thesis follows March & Smith’s (1995) design science methodology in order to build and evaluate the framework. This is done in three steps; first by building a model from theory. Second, the emergence of business models in three different case companies are compared and investigated qualitatively. Lastly the model and the factors derived from the data are contrasted and a framework is built and evaluated. Findings & Conclusion: The basis of the derived framework proposes for big steps to change, and create and capture new value; analyze the basis of competition in the macro and micro environment, analyze and experiment with different non-customer tiers, experiment with the creation of value and experiment and analyze the capture of the value created. More tangible tools are proposed for each of these steps. Actually testing the framework and further evaluating and theorizing of the framework is proposed as future research directions.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2006.Vita.
Includes bibliographical references (v. 1, leaves 174-180).
Construction projects are uncertain and complex in nature. One of the major driving forces that may account for these characteristics is iterative cycles caused by errors and changes. Errors and changes worsen project performance and consequently, cause schedule and cost overruns to be prevalent. In particular, these iterative cycles are more detrimental when large-scale concurrent design and construction is applied. In an effort to address these issues, this research proposes Dynamic Planning and control Methodology (DPM) as a robust design and construction planning methodology for large-scale concurrent design and construction. The proposed DPM is composed of: 1) an error and change management framework that enables understanding of the construction processes associated with errors and changes and how they affect construction performance; 2) a proactive buffering strategy for reducing sensitivity to iterative error and changes cycles; 3) a System Dynamics-based construction project model which provides policy guidelines for the planning and control of projects; and
(cont.) 4) a web-based error and change management system, which supports coordination of errors and changes among contractors and design professionals without hardware and software compatibility issues. Applying all research components into a couple of real world case projects, this research concludes that a concurrently developed project can benefit by: 1) adding realism to planning taking into account iterative error and change cycles; 2) implementing a proactive mechanism to look and act ahead against uncertainties; 3) making appropriate policies with the help of the system dynamics-based simulation model; and 4) facilitating coordination from the IT-supported management system; even if the time frame of a project is shortened. Also, future research opportunities are discussed extending the findings from this research.

[EN] This work focuses on the investigation of advanced techniques to handle groundwater and surface water problems in the framework of inverse methods and climate change. The Ensemble Kalman filter methods, with particular attention to the Ensemble Smoother with Multiple Data Assimilation (ES-MDA), are extensively analyzed and improved for the solution of different types of inverse problems. In particular, the main novelty is the application of these methods for the identification of time series function. In the first part of the thesis, after the description of the ES-MDA method, the development of a Python software package for the application of the proposed methodology is presented. It is designed with a flexible workflow that can be easily adapted to implement different variants of the Ensemble Kalman filter and to be applied for the solution of various types of inverse problems. A complemented tool package provides several functionalities that allow to setup the algorithm configuration suiting the specific analyzed problem. The first novelty application of the ES-MDA method aimed at solving the reverse flow routing problem. The objective of the inverse procedure is the estimation of an unknown inflow hydrograph to a hydraulic system on the basis of information collected downstream and a given forward routing model that relates inflow hydrograph and downstream observations. The procedure is tested by means of two synthetic examples and a real case study; the impact of ensemble sizes and the application of covariance localization and inflation techniques are also investigated. The tests show the capability of the proposed method to solve this type of problem; the performance of ES-MDA improves, especially for small ensemble sizes, when covariance localization and inflation techniques are applied. The second application, in the context of surface water, concerns the calibration of a hydrological-hydraulic model that simulates rainfall-runoff processes. The ES-MDA is coupled with the numerical model by parallel way for the estimation of roughness and infiltration coefficients based on the knowledge of a discharge hydrograph at the basin outlet. The results of two synthetic tests and a real case study demonstrate the capability of the proposed method to calibrate the hydrological-hydraulic model with a reasonable computational time. In the groundwater field, ES-MDA is applied for the first time to simultaneously identify the source location and the release history of a contaminant spill in an aquifer from a sparse set of concentration data collected in few points of the aquifer. The impacts of the concentration sampling scheme, the ensemble size and the use of covariance localization and covariance inflation techniques are tested; furthermore, a new procedure to perform a spatiotemporal iterative localization is presented. The methodology is tested by means of an analytical example and a study case that uses real data collected in a laboratory sandbox. ES-MDA leads to a good estimation of the investigated parameters; a well-designed monitoring network and the use of covariance corrections improve the performance of the method and help to minimize ill-posedness and equifinality. A part of the thesis investigates the impact of climate change on the groundwater availability. A surrogate model that describes the response of groundwater levels to meteorological variables up to 2100 is presented. It is a simple statistical approach based on the correlations between groundwater levels and two drought indices that depend on precipitation and temperature data. The presented method is used to evaluate the impact of climate change on groundwater resources in a study area located in Northern Italy using historical and regional climate model data. The results denote a progressive increase of groundwater droughts in the investigated area.

Full textAbstract:
The main objective of this dissertation is to assist in reducing the chaotic state of the software engineering discipline by providing insights into both the effectiveness of software defect reduction methods and ways these methods can be improved. The dissertation is divided into two main parts. The first is a quasi-experiment comparing the software defect rates and initial development costs of two methods of software defect reduction: software inspection and test-driven development (TDD). Participants, consisting of computer science students at the University of Arizona, were divided into four treatment groups and were asked to complete the same programming assignment using either TDD, software inspection, both, or neither. Resulting defect counts and initial development costs were compared across groups. The study found that software inspection is more effective than TDD at reducing defects, but that it also has a higher initial cost of development. The study establishes the existence of a defect-reduction gap between software inspection and TDD and highlights the need to improve TDD because of its other benefits.The second part of the dissertation explores a method of applying mutation analysis to TDD to reduce the defect reduction gap between the two methods and to make TDD more reliable and predictable. A new change impact analysis algorithm (CHA-AS) based on CHA is presented and evaluated for applications of software change impact analysis where a predetermined set of program entry points is not available or is not known. An estimated average case complexity analysis indicates that the algorithm's time and space complexity is linear in the size of the program under analysis, and a simulation experiment indicates that the algorithm can capitalize on the iterative nature of TDD to produce a cost savings in mutation analysis applied to TDD projects. The algorithm should also be useful for other change impact analysis situations with undefined program entry points such as code library and framework development.An enhanced TDD method is proposed that incorporates mutation analysis, and a set of future research directions are proposed for developing tools to support mutation analysis enhanced TDD and to continue to improve the TDD method.

Full textAbstract:
Superpixels are the results of an image oversegmentation. They are an established intermediate level image representation and used for various applications including object detection, 3d reconstruction and semantic segmentation. While there are various approaches to create such segmentations, there is a lack of knowledge about their properties. In particular, there are contradicting results published in the literature. This thesis identifies segmentation quality, stability, compactness and runtime to be important properties of superpixel segmentation algorithms. While for some of these properties there are established evaluation methodologies available, this is not the case for segmentation stability and compactness. Therefore, this thesis presents two novel metrics for their evaluation based on ground truth optical flow. These two metrics are used together with other novel and existing measures to create a standardized benchmark for superpixel algorithms. This benchmark is used for extensive comparison of available algorithms. The evaluation results motivate two novel segmentation algorithms that better balance trade-offs of existing algorithms: The proposed Preemptive SLIC algorithm incorporates a local preemption criterion in the established SLIC algorithm and saves about 80 % of the runtime. The proposed Compact Watershed algorithm combines Seeded Watershed segmentation with compactness constraints to create regularly shaped, compact superpixels at the even higher speed of the plain watershed transformation.
Operating autonomous systems over the course of days, weeks or months, based on visual navigation, requires repeated recognition of places despite severe appearance changes as they are for example induced by illumination changes, day-night cycles, changing weather or seasons - a severe problem for existing methods. Therefore, the second part of this thesis presents two novel approaches that incorporate superpixel segmentations in place recognition in changing environments. The first novel approach is the learning of systematic appearance changes. Instead of matching images between, for example, summer and winter directly, an additional prediction step is proposed. Based on superpixel vocabularies, a predicted image is generated that shows, how the summer scene could look like in winter or vice versa. The presented results show that, if certain assumptions on the appearance changes and the available training data are met, existing holistic place recognition approaches can benefit from this additional prediction step. Holistic approaches to place recognition are known to fail in presence of viewpoint changes. Therefore, this thesis presents a new place recognition system based on local landmarks and Star-Hough. Star-Hough is a novel approach to incorporate the spatial arrangement of local image features in the computation of image similarities. It is based on star graph models and Hough voting and particularly suited for local features with low spatial precision and high outlier rates as they are expected in the presence of appearance changes. The novel landmarks are a combination of local region detectors and descriptors based on convolutional neural networks. This thesis presents and evaluates several new approaches to incorporate superpixel segmentations in local region detection. While the proposed system can be used with different types of local regions, in particular the combination with regions obtained from the novel multiscale superpixel grid shows to perform superior to the state of the art methods - a promising basis for practical applications.

Full textAbstract:
The biology and the patterns of wild environments and their organisms have solutions to the many environmental, social and economical challenges that we are facing globally. As an emerging designer, I believe that the tendencies of the ecological environments can be analyzed, mimicked and implemented by designers into different socio-cultural systems. In my design process I have been exploring practices that promote food sovereignty as a right that every living being should have. The results of my exploration is a guide to help to learn about and from wild edibles to deepen our connection with nature. My design includes my own process and iteration as well as one designed for those who are interested in exploring foraging practices.This project recognizes the different spheres and complexities of sustainability. It analyzes how our cultural and social practices impact the ecological environment, while, at the same time, it brings practical examples to understand the effects that our economy has on the overall well-being of the ecology, and suggests that we all can be beneficial participants as and in nature.The title “We grow wild” refers to the plants, which grow wildly in parks, hedgerows, paths and forests, as well as it encourages to rediscover the wild nature that re-emerges in us through active participation in the ecological environment we inhabit.

Full textAbstract:
Avec l’augmentation du nombre de scanner et de la dose collective, le risque potentiel d’apparition d’effets stochastiques est accentué. Pour limiter au maximum ce risque, les principes de justification et d’optimisation doivent être appliqués avec rigueur. L’optimisation des pratiques a pour but de délivrer la dose la plus faible possible tout en conservant une qualité diagnostique des images. C’est une tâche complexe qui implique de trouver en permanence un compromis entre la dose délivrée et la qualité image résultante. Pour faciliter cette démarche, des évolutions technologiques ont été développées. Les deux évolutions majeures sont la modulation du courant du tube en fonction de l’atténuation du patient et l’apparition des reconstructions itératives (IR). L’introduction des IR a modifié les habitudes puisqu’elles permettent de conserver des indices de qualité image équivalents en réduisant les doses. Cependant, leurs utilisations s’accompagnent d’une modification de la composition et de la texture de l’image nécessitant d’utiliser des métriques adaptées pour les évaluer. Le but de cette thèse est d’évaluer l’impact d’une utilisation des IR sur la réduction de la dose et sur la qualité des images afin de proposer en routine pour tous les patients, des protocoles avec la dose la plus faible possible et une qualité image adaptée au diagnostic. La première partie de cette thèse est consacrée à une mise au point sur la problématique du compromis dose/qualité image en scanographie. Les métriques de qualité image et les indicateurs dosimétriques à utiliser, ainsi que le principe et l’apport des reconstructions itératives y sont exposés. La deuxième partie est consacrée à la description des trois étapes réalisées dans cette thèse pour atteindre les objectifs. La troisième partie est constituée d’une production scientifique de 7 articles. Le 1er article présente la méthodologie d’optimisation globale permettant la mise en place de protocoles Basses Doses en routine avec utilisation de niveaux modérés des IR. Le 2ème article évalue l’impact et l’apport sur la qualité des images obtenues pour des niveaux de doses très bas. Le 3ème et le 4ème article montrent l’intérêt d’adapter ou de proposer des protocoles optimisés selon la morphologie du patient. Enfin les 3 derniers articles, illustrent la mise en place de protocoles Très Basses Doses pour des structures ayant un fort contraste spontané. Pour ces protocoles les doses sont proches des examens radiographiques avec des niveaux élevés des IR. La démarche d’optimisation mise en place a permis de réduire considérablement les doses. Malgré une modification de la texture et de la composition des images, la qualité des images obtenues pour tous les protocoles était jugée satisfaisante pour le diagnostic par les radiologues. L’utilisation des IR en routine nécessite une évaluation particulière et un temps d’apprentissage pour les radiologuesThe increasing number of scanner and the cumulative dose delivered lead to potential risk of stochastic effects. To minimize this risk, optimization on CT usage should be rigorously employed. Optimization aims to deliver the lowest dose but maintaining image quality for an accurate diagnosis. This is a complex task, which requires setting up the compromise between the dose delivered and the resulting image quality. To achieve such goal, several CT technological evolutions have been developed. Two predominant developments are the Tube Current Modulation and the Iterative Reconstruction (IR). The former lays one patient's attenuation, the latter depend on advanced mathematical approaches. Using IR allows one to maintain equivalent image quality values by reducing the dose. However, it changes the composition and texture of the image and requires the use of appropriate metric to evaluate them. The aim of this thesis was to evaluate the impact of using IR on dose reduction and image quality in routine for all patients, protocols with the lowest dose delivered with an image quality suitable for diagnosis. The first part of the thesis addressed the compromise between dose delivered and image quality. Metrics of the image quality and the dosimetric indicators were applied as well the principle and the contribution of IRs were explored. The second part targets the description of the three steps performed in this thesis to achieve the objectives. The third part of the thesis consists of a scientific production of seven papers. The first paper presents the global optimization methodology for the establishment of low dose protocols in routine using moderate levels of IR. The second paper assesses the impact and contribution of IR to the image quality obtained to levels very low doses. The third and the fourth papers show the interest to adapt or propose protocols optimized according to patient's morphology. Finally the last three papers illustrate the development of Very Low Dose protocols for structures with high spontaneous contrast. For these protocols, doses are close to radiographic examinations with high levels of IR. The optimization process implementation has significantly doses reduction. Despite the change on the texture and on composition of the images, the quality of images obtained for all protocols was satisfactory for the diagnosis by radiologists. However, the use of routine IR requires special assessment and a learning time for radiologists

Thesis, University of Manchester, 2013. https://www.research.manchester.ac.uk/portal/en/theses/sustainability-in-practice-a-study-of-how-reflexive-agentsnegotiate-multiple-domains-of-consumption-enact-change-andarticulate-visions-of-the-good-life(c19dc146-1b93-402e-b3b5-cbbd3f6778be).html.
Full textAbstract:
A small proportion of people claim to live and consume in ways they consider more sustainable in social and environmental terms. As yet, we do not know how many exactly, but possibly no more than 5-10% of the population. The thesis intentionally focuses on this minority finding there are at least three reasons why it is interesting to do so. First because they are all but ignored in sociologies of practice in the context of sustainable consumption which considers this minority an insignificance and focuses almost exclusively on 'mainstream' majority which more closely maps onto the stereotype of 'consumer society'. Second because we think we can learn much from juxtapositioning this group empirically against the spectrum of theories of practice to devise more robust and appropriate theoretical explanation of how these subjects, in the context of everyday practice, negotiate the many interpretations and contradictions involved in trying to put 'sustainability' into practice. Third because by understanding them better we can reflect on theoretical, empirical and policy implications for nudging this minority of the population to a higher percentage. The thesis sits at one end of a spectrum of positions in theories of practice applied to consumption, and in particular with a normative interest in sustainable consumption. It aligns with those who seek to re-insert the reflexive agent into accounts of practice, with particular reference to the conceptual construct of the 'citizen-consumer' and the context of political consumption (Spaargaren & Oosterveer 2010). Referring to theories of consumption, the thesis adds perspectives on how people negotiate multiple domains of consumption simultaneously since everyday practice involves interactions across multiple domains (such as eating, mobility, householding); and yet typically in theories of practice these are artificially separated into single domains. The study therefore considers the implications which domains have on how particular practices are carried out, first separately (per domain) and then as they come together (in a cross-cutting domain perspective). The study then takes theories of practice as a springboard to develop a theoretical position and framework which better fits the narrated accounts of the 37 subjects who participated in this study. In iteratively co-developing a theoretical framework and multiple 'stages' of empirical research (using grounded theory methodology) the study seeks to explain theoretically how subjects justify their 'doings' (drawing on 'conventions' and 'orders of worth' (Boltanski & Thévenot 2006)); how they appear to muddle through as best they can (introducing 'bricolage' (Lévi-Strauss 1972)); and how subjects appear to devise decision short-cuts when approaching decisions characterised by the multiple contradictions of sustainable consumption and incomplete or 'too much' information (introducing heuristics (Gigerenzer & Gaissmaier 2011)). In joining calls to re-insert the reflexive agent to account for how, when and why subjects enact changes towards trajectories which they consider 'more sustainable' in their own terms, the study takes inspiration from Margaret Archer's morphogenesis approach (1998) and explores her model of multiple modes of reflexivity, announcing certain modes as 'better fitting' conditions of late modernity. The study finally finds that contrary to a notion of the un-reflexive agent, the citizen-consumer is able to articulate visions of the 'good life'. In addition she is able to fold these visions back onto everyday practices performed in the past, present and future, laying out normative guidelines and positive accounts of how to achieve personal or societal well-being and happiness. The overarching positioning of the study is much inspired by Andrew Sayer's (2011; 2000) 'normative turn' calling upon social sciences to re-instate research into the things about which people care. The study is therefore guided by the overarching question of how people translate their environmental and/or social concerns into the ways in which they live and consume.

Full textAbstract:
In the past two decades, public health interventions have moved from education strategies aimed at individuals to broad, multilevel interventions incorporating environmental and policy strategies to promote healthy food behaviors. These intervention programs continue to employ classic behavior change models that consider individuals as deliberate, intentional, and rational actors. Contrary to the ideas posited by rational choice theory, diet-related literature draws little correlation between an individual’s intentions and his/her resultant behavior. This chapter adds to the dual-system model of cognition—reflective or slow thinking, and automatic or fast thinking—and introduces an emerging theory for dietary behavior change called behavioral design. Behavioral design recognizes that human decisions and actions lie on a continuum between spheres and are continually shaped by the interactions between an agent (individual, group) and his/her/their exposure (environment). More specifically, behavioral design considers the importance of the “experience” left as time passes, such as conditioning, resilience, expectation, repeated behaviors, and normality, as the central and iterative influence on future decisions. Behavioral interventions must consider the individual’s “experience” resulting from his or her interaction with the environment, while acknowledging the fast and slow mechanisms by which choices are made. This chapter introduces aspects to consider when using behavioral design to increase healthier food behaviors and physical activity, and briefly discusses ethics questions related to intentional modification of environment for health behavior change.

The domain of work has developed a myriad of social practices that are often shaped by information and communications technology infrastructures. The introduction of additional IT artifacts, of course, affects these practices and the related patterns of communication. While management and IT specialists plan for certain effects of a system’s introduction, unintended use of the system can play a central role. Therefore, the unanticipated appropriation of IT artifacts by their users is an important phenomenon. Given the existence of IT-related organizational change and adjustments related to the appropriation of software, the development of IT in organizations faces an iterative challenge. The “integrated organization and technology development” (OTD) approach deals with these interdependencies in projects of sociotechnical change.

Full textAbstract:
Governments can play great roles, resolving festering problems and opening new pathways for progress. Examples are numerous and raise an important question: How do governments build the capabilities required to do great things? This chapter identifies ten cases of such governments to answer four dimensions of this question: how do governments to ramp up their capability? Who leads these interventions ?, When do they occur, and why? How changes implemented to ensure they yield sustainable results? The chapter suggests two sets of answers to these concerns, combining rival theories that explain how governments enhance capabilities and strengthen their role: “solution- and leader-driven change” (SLDC) and “problem-driven iterative adaptation” (PDIA). It proposes using these two theories in future research about how governments foster the kinds of achievements one could call great and argues this research should employ a version of theory-guided process tracking (TGPT) called systematic process analysis.

Full textAbstract:
This article discusses the psychology of composition. Composition is a reflexive, iterative process of inscription. The work, once named as such and externalizable to some degree, passes circularly between inner and outer states. It passes through internal and external representations – mostly partial or compressed, some projected in mental rather than physical space, not all necessarily conscious or observable – and phenomenological experience, real or imagined. At each state-change the work is re-mediated by the composer, whose decision-making process is conditioned by the full complexity of human experience. This entire activity informs the simultaneous development of the composer's understanding of the particular work in its autonomy, of their own creativity, and of music more broadly. While the urge to compose – to invent, structure, and define sound and musical behaviour – may be to some degree innate, modes of conceiving, representing, and realizing are the product of a situated process. Even if some or all of that activity is so well assimilated personally or culturally that it remains hidden from experimental view, it remains a behaviour in respect of an emerging object.

Full textAbstract:
In development circles, there is now widespread consensus that social entrepreneurs represent a far better mechanism to respond to needs than we have ever had before--a decentralized and emergent force that remains our best hope for solutions that can keep pace with our problems and create a more peaceful world. David Bornstein’s previous book on social entrepreneurship, How to Change the World, was hailed by Nicholas Kristof in The New York Times as “a bible in the field” and published in more than twenty countries. Now, Bornstein shifts the focus from the profiles of successful social innovators in that book--and teams with Susan Davis, a founding board member of the Grameen Foundation--to offer the first general overview of social entrepreneurship. In a Q & A format allowing readers to go directly to the information they need, the authors map out social entrepreneurship in its broadest terms as well as in its particulars. Bornstein and Davis explain what social entrepreneurs are, how their organizations function, and what challenges they face. The book will give readers an understanding of what differentiates social entrepreneurship from standard business ventures and how it differs from traditional grant-based non-profit work. Unlike the typical top-down, model-based approach to solving problems employed by the World Bank and other large institutions, social entrepreneurs work through a process of iterative learning--learning by doing--working with communities to find unique, local solutions to unique, local problems. Most importantly, the book shows readers exactly how they can get involved. Anyone inspired by Barack Obama’s call to service and who wants to learn more about the essential features and enormous promise of this new method of social change, Social Entrepreneurship is the ideal first place to look.

Full textAbstract:
This chapter continues the discussion from the previous chapter. The motion of a charge (m,q) in the field of another charge (m′,q′) and in its own field can now be studied in the lowest orders of the velocities directly using the equation of motion obtained in the preceding chapter. However, the features of this motion are revealed more easily by deriving them from the Darwin Lagrangian. This allows for a rigorous establishment of a balance between the energy radiated by the system and the mechanical energy lost by the system. The chapter concludes this general study of the electromagnetic radiation of a system of charges by outlining the ‘post-Minkowski’ approach based on iteration in the ‘coupling constant’ qq′ rather than in the velocities.

Full textAbstract:
Cabinets, Ministers, and Gender explores why men have been more likely than women to be appointed to cabinet, why gendered patterns of appointment vary cross-nationally, and why, over time, women’s inclusion in cabinets has grown significantly. The book is innovative in conceiving of cabinet formation as a gendered process governed by rules that empower and constrain presidents and prime ministers as selectors of cabinet ministers, and rules that prescribe, prohibit, and permit a range of criteria (experiential, affiliational, and representational) that qualify individuals for inclusion in cabinet. Focusing on seven country cases (Australia, Canada, Chile, Germany, Spain, the United Kingdom, and the United States) using three data sets—elite interviews, media data, and autobiographies—the book reveals the complex sets of rules governing cabinet formation in each country and demonstrates their gendered effects. The book shows how different types of rules empower and constrain selectors, and how these rules interact to create different opportunities and obstacles for women’s cabinet inclusion. The findings demonstrate how institutional change emerges from a complex iterative process through which political actors interpret and exploit ambiguity in rules to deviate from past practices of appointing mostly male cabinets. These selectors help to develop new rules about women’s inclusion, which constrain future leaders in assembling their cabinet. The authors coin the term “concrete floor” to capture the process by which minimum levels for women’s cabinet inclusion are established and become locked in over time, explaining how competing rules for cabinet appointments, changing norms, and women’s mobilization in political parties shape outcomes.

Full textAbstract:
Since the mid-twentieth century, the DSM has guided psychiatrists in categorizing disorders. Revisions have taken years, with work groups considering changes to the entire manual. A more timely and efficient approach to updating the DSM would involve continuous improvement of particular diagnostic categories, when and if supported by advances in the field. The aim is to avoid the delays in the incorporation of new knowledge that are inherent in updating at intervals of a decade or more. The American Psychiatric Association has therefore established a structure by which evidence-based proposals for changes to the DSM can be considered and adopted on an ongoing basis. This chapter describes how proposals will be considered and the standards to be applied to proposed modifications. Challenges include calibrating optimal rigor of the review process, pruning diagnoses that lack validity or clinical utility, and subjecting the process itself to iterative improvement.

Full textAbstract:
Swedish politics can still be characterized as deliberative, rationalistic, open, and consensual but only if these four concepts are reinterpreted. Sweden has changed from a long-term “sounding-out” style of policy-making to a short-term and iterative trial-and-error method. Whereas commissions of inquiry in the 1960s were expected to carry out thoroughgoing investigations of policy alternatives and their possible consequences, since the 1980s they have been ordered to finish their assignments in less time and deliver shorter reports. Political decisions today are taken on a much less solid factual ground. The political process has moved from a consensus-seeking system based on selected access for a few major interests to a competitive and open-ended system.

AbstractAn innovative approach towards transformative change through multi-stakeholder participation for socio-ecological practices—Integrated Local Delivery (ILD)—has been used to restore the water quality and biodiversity across a catchment in the Cotswolds, South West England. This was triggered by the need to improve the Ecological Status of water as a part of the European Union’s Water Framework Directive. On a landscape scale of roughly 25,000 hectares, multi-stakeholders collaborated through a bottom-up approach to carry out environmental restoration of the catchment.Over 3 years, an iterative learning loop of reflection and evolution created increased engagement. Twenty farmers have been empowered as ‘guardians’ to be key contacts between institutions and ensure the sustained environmental quality of the area. Both farmers and communities acted to reduce chemical use, protect river banks from livestock damage and clear waterways to enhance water quality and biodiversity. Local communities fed into the development of a ‘Community Water Guide’ which can be applied internationally for similar projects. Within the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) transformative change framework, the ILD model can also be applied by facilitators to access levers and leverage points in order to enable change.Important take home messages from the project include having well-trained facilitators who ensure active engagement, connections and continuity over the long term. Likewise, ensuring all stakeholders feel listened to and clearly communicated with is essential to build trust and motivation.

AbstractContext: Twenty years after the publication of the agile manifesto, agility is becoming more and more popular in different contexts. Agile values are changing the way people work together and influence people’s mindset as well as the culture of organizations. Many organizations have understood that continuous improvement is based on measurement.Objective: The objective of this paper is to present how agility can be measured at the team level. For this reason, we will introduce our questionnaire for measuring agility, which is based on the agile values of the manifesto.Method: We developed a questionnaire comprising 36 items that measure the current state of a team’s agility in six dimensions (communicative, change-affine, iterative, self-organized, product-driven and improvement-oriented). This questionnaire has been evaluated with respect to several expert reviews and in a case study.Results: The questionnaire provides a method for measuring the current state of agility, which takes the individual context of the team into account. Furthermore, our research shows, that this technique enables the user to uncover dysfunctionalities in a team.Conclusion: Practitioners and organizations can use our questionnaire to optimize collaboration within their teams in terms of agility. In particular, the value delivery of an organization can be increased by optimizing collaboration at the team level. The development of this questionnaire is a continuous learning process with the aim to develop a standardized questionnaire for measuring agility.

Full textAbstract:
This rapid review synthesises evidence on FCDO climate projects across the East African region in the following countries; Kenya, Rwanda, Uganda and Tanzania. This review established that sector stakeholders in countries like Rwanda lacked climate impact information. This highlights the need of providing the right information in the right form to meet the end users need. The above case studies have shown the need for consistent and harmonised future climate projections that are country specific. According to a study undertaken in Tanzania and Malawi, understanding the likely future characteristics of climate risk is a key component of adaptation and climate-resilient planning, but given future uncertainty it is important to design approaches that are strongly informed by local considerations and robust to uncertainty. According to the findings from the research, policy incoherence, over-reliance on donor funding, change in leadership roles is a barrier to adaptation. There is also an urgent need for mechanisms for sharing experience and learning from methodologies, technologies, and challenges. Further, Stakeholder dialogue and iterative climate service processes need to be facilitated. This review also explores approaches to communicating climatic uncertainties with decision-makers. Particularly, presentation of data using slide-sets, and stories about possible futures.
