Full textAbstract:
Intermodal transport is widely believed to be an efficient way of organizing transportation activities because of its significant role in reducing logistics costs and emissions of air pollutants, which copes with the ever-increasing economic and environmental concerns. This paper applies the multiple streams framework (MSF) to analyze three streams (e.g., the problem stream, policy stream, and politics stream) in setting policy agenda for sustainable intermodal transport in China. By restricting the attention to the opening of the policy window and the coupling of the three streams, the motivation, process, and trend of formulating intermodal transport policy are systematically discussed. The findings show that the key to setting the policy agenda for sustainable intermodal transport in China is to strengthen collaboration among multiple interest groups, boost the national mood, and diversify the identity of policy entrepreneurs. This paper not only verifies the applicability of the MSF, but also helps us to better understand how sustainable intermodal transport policy is formulated in China, thus promoting future policy making.

This paper discusses the agenda setting policy for 2020 simultaneous regional elections which were carried out in the midst of the Covid-19 pandemic. Various rejection that have arisen and facts in the field seem to confirm that continuing to carry out the election is an inaccurate decision. The government decisions are classified and analyzed based on three streams, namely problem stream, political stream, and policy stream. This study uses a qualitative descriptive method with a multiple stream perspective adopted from Kingdon's 2014 theoretical framework. The results of this study reveal that the public's desire to postpone the implementation of regional elections in the midst of a pandemic has been ignored by the government, considering that no one can confirm when this pandemic ends. Strong political stream more dominate because this election contestation is full of various political interests. The enactment of Perppu No. 2/2020 immediately terminate the various policy alternatives that had been offered.

In this research, a framework is proposed for answering the question: whether a dominant sequence exists for the multiple self-contained input streams destined for a computation provider running the requested applications concurrently. The framework is extended to find an optimal semidominant sequence for multiple input streams. This paper also shows that an existent universal dominant sequence can be formed by permuting a set of dominant input streams. In this paper, the neighbor-connected graph is first proposed to model the sequence problem of multiple input streams. Then, an algorithm with time complexity O(nLn) is proposed to determine the existence of a dominant data-receiving sequence, where L is the maximal length of the input streams plus one and n is the number of input streams. Examples of applying the framework to solve the sequence problems for several computation-intensive applications are also given. Furthermore, the framework is extended to find an optimal semidominant sequence using an algorithm with time complexity O(nLnlogδ*), where δ* is the maximal degree that the sequence diverges from all the optimal subsequences. Finally, the property of a universal dominant sequence is studied and the performance of the sequence is compared with those of other sequences.

We consider the problem of efficiently online computing/filtering or analysis multimedia streams. In this scenario, we register a large scale of continuous analysis queries to filter pornographic stream items. Each query is a conjunction of filters. For instance, the query “does this image contain a people basking in the beach?” can be resolved by applying the conjunction of water, people, sand, sea filters successively on the stream item. However, the online evaluation of multimedia filters is indeed very expensive, fortunately there usually exist multiple filters shared among a lot of queries. In other words, each filter may occur in multiple queries. An open problem in such a filtering scenario is how to order the filters in an optimal sequence to achieve significant performance. Existing methods are based on a greedy strategy which orders the filters according to three factors (selectivity, popularity, cost). Although all these methods achieve good results, there are still some problems that haven’t addressed yet. First, the selectivity factor is set empirically, which can not adaptively adjust with multimedia stream. Second, the proportion relationships among the three factors (selectivity, cost, popularity) were not considerably explored. Under these observations,in this paper, we propose a Dynamic-Analytic hierarchy process Framework (DAF) which use a time-based compositional forecasting method, which is based on the idea of exponential smoothing, to deal with the factors’ proportion relationships dynamics. Experiments on both synthetic and real lift multimedia streams demonstrate that our proposed framework (DAF) provides much great adaptability in modeling the factors proportion relationships changing over multimedia stream environment.

In this paper, the authors present a framework to support multidimensional analysis of real-time physiological data streams and clinical data. The clinical context for the case study demonstration is neonatal intensive care, focusing specifically on the detection of episodes of central apnoea, a clinically significant problem. The model accounts for the multidimensional and real-time nature of apnoea of prematurity and the associated clinical rules. The framework demonstration includes: 1) defining rules that quantify concurrent behaviours between multiple synchronous data streams and asynchronous data values; 2) designing UML models to define present practice event processing for episodes of apnoea; 3) translating the model in SPADE to enable the deployment within the real-time processing layer of the Artemis platform, which utilizes IBM’s InfoSphere Streams; 4) demonstrating knowledge discovery with simple and complex temporal abstractions of the data streams; and 5) presenting results for early detection of episodes of apnoea across multiple physiological data streams.

Full textAbstract:
Cette thèse étudie les conditions et l’ampleur des évolutions de la politique nucléaire de l’Union européenne, de 2000 à 2016. Depuis le milieu des années 1990, plusieurs événements – ou « fenêtres d’opportunité » selon la terminologie du Multiple Streams Framework – ont remis les politiques nucléaires au centre de l’attention des décideurs européens : l’adhésion de nouveaux Etats membres en 2004 ; différentes Présidences du Conseil et nominations de Commissaires ayant pris clairement position sur les questions nucléaires ; l’accident de Fukushima de mars 2011 ; et enfin, les deux sorties du nucléaire allemandes, en 2000 et 2011.La première partie de ce travail est consacrée à l’analyse de l’ampleur du changement introduit par les directives adoptées durant la période étudiée: les directives sûreté réacteur de 2009 et 2014, ainsi que la directive déchets radioactifs de 2011. La deuxième partie étudie les facteurs de stabilité qui ont empêché la mise à l’agenda ou l’adoption de certaines propositions, comme les politiques d’harmonisation des régimes de responsabilité civile ou comme les tentatives d’abolition du traité Euratom.Parmi les différentes variables testées, des coûts de mise en œuvre limités, ainsi que l’existence d’indicateurs pour un problème donné, sont apparus comme des conditions nécessaires (mais non suffisantes) pour un changement de politique.La variable la plus pertinente pour expliquer les changements contenus dans les directives adoptées est l’évolution de la place d’un problème dans les priorités des acteurs. L’accident de Fukushima n’a modifié ni les conditions objectives d’existence d’un problème, ni, sur le long terme, les priorités des Etats Membres ou du secteur nucléaire. Ainsi, les propositions post Fukushima tendant à augmenter le rôle de la Commission européenne ou une calibration plus stricte des mesures de sûreté ont donc été partiellement rejetées, pour finalement aboutir à une révision de la directive sûreté, en 2014, avec peu de changements. De même, la priorité accordée à la résolution des problèmes nationaux liés à gestion des déchets radioactifs a abouti à l’adoption d’une directive incluant des mesures plus précises.Les principaux changements ayant eu lieu dans les directives étudiées concernent leur logique instrumentale et leur calibration ; aucun changement n’a été observé dans les buts ou les orientations générales de la politique nucléaire de l’UE. La politique nucléaire de l’UE semble ainsi particulièrement stable.Cette thèse met en évidence plusieurs facteurs d’inertie des politiques et institutions d’Euratom, malgré l’action d’entrepreneurs politiques : le haut niveau de méfiance entre acteurs, la délégation de la sûreté à des agences indépendantes, la dépendance au sentier liée à la technologie nucléaire, et la flexibilité « incorporée » dans Euratom. Ces facteurs réduisent le nombre d’entrepreneurs politiques potentiellement efficaces ainsi que l’éventail de leurs stratégies pour promouvoir un changement. En plus des facteurs institutionnels, la stabilité des politiques et institutions est également promue par des veto players.Néanmoins, les problèmes récents auxquels est confronté le secteur nucléaire européen (intégration croissante de sources d’énergie renouvelable, difficultés économiques) érodent les conditions de reproduction et de stabilité des institutions d’Euratom. Cet aspect se traduit notamment dans le progressif retrait du nucléaire des communications officielles mentionnant les sources d’énergie à développer pour remplir les objectifs de l’Union.En se basant sur le MSF et sur l’institutionnalisme historique, cette thèse démontre ainsi que les évolutions de la politique nucléaire de l’UE requièrent trois conditions : l’action d’un entrepreneur politique, l’émergence d’un problème dans les priorités des principaux acteurs et, pour des changements d’orientation ou d’institution, l’érosion des mécanismes de reproductionThe goal of this dissertation is to understand the conditions under which the nuclear policy of the European Union has evolved – between 2000 and 2016 — as well as the scope of these evolutions. From the mid-1990s onwards, various events – “windows of opportunity” in the terminology of the Multiple Streams Framework – brought nuclear energy back to the attention of European policy-makers: the accession of new member states in 2004; different Council presidencies and nomination of Commissioners with a strong position on nuclear energy; the Fukushima accident in March 2011; Germany’s first and second nuclear phase-outs (in 2000 and 2011).This PhD proceeds in two parts: First, it analyses the scope of change in policies that have been set on the agenda and finally adopted (the reactor safety and the radioactive waste management directives); second, it analyses the stability factors that have hindered the agenda-setting or the decision-making on proposals for policy change or institutional reforms (harmonisations of civil liability regimes, licensing processes, or decommissioning funds; abolition of the Euratom treaty).Among the several variables tested, low implementation costs, as well as the existence of problem indicators, may be a necessary, but not a sufficient condition for policy change.The most relevant variable accounting for the policy changes included in the adopted directives, was the evolution of the problem in place of actors’ priorities. The Fukushima accident neither modified the objective conditions of existence of a problem, nor the long-term priority of Member States or the nuclear sector. Hence the post-Fukushima proposals suggesting an increase in the role of the European Commission or a stricter calibration of safety measures have been partially rejected. Hence there was no substantial policy change in the safety directive adopted in 2014. In a similar way, the priority granted to overcoming national problems of radioactive waste management led to the 2011 radioactive waste directive, which contained more settings than the 2009 reactor safety directive .The main changes observed in the directives impacted their settings, instrumental logic and calibration; no change has been observed in the goals or orientations of the EU nuclear policy since 2000. Therefore, the EU nuclear policy seems especially stable: in many cases, policy proposals did not even make in onto the agenda of the Council.In order to account for the stability of the policy in spite of the action of policy entrepreneurs, this PhD underlines the particular “stickiness” of the Euratom institutions and policies: The high distrust among actors; the delegation of safety to independent agencies; the technological path-dependence linked to the use of nuclear energy; and the “built-in” institutional flexibility of Euratom. These factors reduce the number of potential successful policy entrepreneurs and the range of strategies of change. Not only the institutional context but also the defiance among actors has accounted for the particular stability of the European nuclear policy and for the absence of change in goals or objectives: Stability was promoted by veto players, whose actions can be taken into account by the Multiple Streams Framework.Still, the recent problems facing the nuclear sector (growing renewable energy share, economic difficulties) are eroding the conditions of stability and mechanisms of reproduction of the European nuclear institutions. This is reflected in the progressive modification of the Commission’s official positions on nuclear energy, which is no longer included in the energy sources to be developed to meet the EU’s energy objectives.Relying both on the MSF and the historical institutionalism, this PhD shows that change in the European nuclear policy requires the action of a policy entrepreneur, the erosion of reproduction mechanisms and the occurrence of a problem among the priorities of main actors

Full textAbstract:
The 18th of December 2015 the Swedish parliament approved a change in migration policy, allowing for the government to implement ID- controls at the Swedish border. The policy change was put forward in a, for Sweden, unusual way in that, that it happened quickly, deviated from standard procedure and represented a different stance than the one previously held by the government. By applying an evolved version of the multiple streams framework, originally put forth by Kingdon (2003), I seek to find an explanation for why this policy change occured. A description of the different components of the theoretical framework, as they appear in this specific case, is provided through an analysis of different kinds of government publications and documents, along with articles from the press and public opinion polls. The results of the study indicates that a change in the problem stream opened a policy window of oppurtunity for the government, in the form of a policy entrepreneur, to push for their policy solution, in adherence to the change in the national mood. The study further points to a discussion concerning the salience of this kind of theoretical contextualisation in cases like this one.

Full textAbstract:
This study seeks to examine whether the Corona pandemic has potential to serve as a focusing event for the problem of insufficient governmental action on climate change mitigation. The study is built on the Multiple Streams Framework by John W. Kingdon, with a main focus on the focusing event theory. According to this, focusing events can come in three forms: as crises and disasters, personal experiences of policymakers, and as symbols. Kingdon’s theoretical discussions, alongside my own developments of his work, provides the basis for a set of analytical questions through which the answer to the research question is provided. The analysis reveals that while the pandemic indeed can be considered a crisis or disaster and personal experiences of policymakers, establishing whether these could focus attention to the specific problem of insufficient governmental action on climate change mitigation requires further research, as the perceived cause of the crisis or disaster and personal experience must be established. However, the paper finds that the pandemic indeed has potential to serve as a symbol for the specific insufficient governmental action, for instance by stressing that deforestation increases the risk of zoonotic outbreaks, such as the Corona pandemic.

Full textAbstract:
Despite the existence of land use and environmental protection policies designed to provide guidance on land development, some projects can still be contentious. As the number of Muslims and mosques in the United States are increasing, little is known about the problematic conditions that Muslims may experience when attempting to site a new mosque, community center, or cemetery. The purpose of this study was to develop a deeper understanding about the experiences and perceptions of those involved in the failed siting of a controversial mosque, community center, and cemetery project in a U.S. West Coast state. The multiple streams framework was used to examine the problem, politics, and policy streams that occurred throughout the case. The research question addressed the key elements that led to community protests and the ensuing state lawsuit. A qualitative case study design was used to analyze literature, news reports, government reports, and the loosely-structured interviews of 15 purposefully-selected community stakeholders. The interview data were coded and categorized for thematic analysis. Results indicated that navigating the politics stream was especially difficult for the mosque applicants because they did not anticipate much resistance and were unaware of community members' concerns about water table contamination. Implications for positive social change include providing policy makers with insight into conflict that may arise in the siting of a mosque, community center, or cemetery and potentially reducing conflict between Muslims and non-Muslims.

Full textAbstract:
The Swedish Defence bill of 2015 demonstrated a rapid change in policy objectives, consequently moving away from an expeditionary force and converging into a territorial defence force. Previous research has attributed and explained the quick shift to the geostrategic unbalance that followed after the illegal annexation of Crimea in 2014. Yet, major policy changes are often years in the making, indicating that there must be additional explanations to the rapid shift. By applying a modified version of John Kingdon’s (2011) Multiple Streams Framework on the case of Sweden changing its security and defence policy, this thesis examines the policy process that preceded the official policy decision. The thesis provides further explanation to why the rapid policy change occurred by utilising qualitative content analysis. The analysis shows that the new policy was adopted due to several factors: one being the attention brought to several problems pertaining to the previous policy, another one was found in the timing between focusing events and the on-going work process of the Swedish defence commission, and lastly, strong actors within the policy field were in favour of a change in policy. The thesis concludes that the presence of several factors within the processes of politics, policy and problems enabled the rapid policy change.

Full textAbstract:
Syftet med denna studie är att undersöka hur kriser påverkar policyförändring. För att undersöka detta ska Livsmedelsverkets hantering av ett fall av upprepade livsmedelsfusk på ICA-butiker runt om i Sverige användas. Fallet ska analyseras ur en teori kallad The Multiple Streams Framework utvecklad av Kingdon som förklarar att förändring kräver en rubbning i en av tre strömmar kallade problem-, politik- och policyström. Om en rubbning sker i någon av dessa strömmar kan frågor som kräver förändring bli kända för beslutsfattare som sedan kan genomföra förändringen. Studiens analys visar att hur en händelse eller ett problem tolkas och upplevs har betydelse för hur det sedan hanteras och hur förändringsprocessen ser ut. Livsmedelsverkets tolkning av fallet var sådan att det endast berörde ICA och deras varumärke. Detta ledde till att inga aktioner ut över det vanliga vidtogs och inga förändringar ägde rum. Studiens slutsatser ger ett resultat som tyder på att problemströmmen – huruvida man tolkar en händelse som ett problem som kräver en lösning eller ej – spelar en större roll i förändringsprocessen än de andra strömmarna. Hur man tolkar en händelse har inspelningar på hur man uppfattar samhällets stämning – politikströmmen – och hur den interna debatten förs – policyströmmen. Detta vore intressant och undersöka vidare i fortsatt forskning.

Full textAbstract:
In order to understand how policies are made, analysts need to be able to explain and describe the policy making process. This is a complex task due to the variety and complexity of policy making environments. The difficulty lies in accounting for the multiple actors who come and go, differing preferences, and impending problems and solutions sets which vary by policy environment.
Therefore, there is a need to approach the understanding of policy processes from several different theoretical perspectives to aid in evaluating the multifaceted variations which ultimately affect policy making. An improved description of processes can lead to more accurate predictions of possible future policies, improved advocacy efforts, and enhanced problem solving.
Two policy process frameworks, the Multiple Stream Framework (MSF) and the Institutional Analysis and Development (IAD) framework, were applied to a recent significant change in science policy. An understanding is developed to explain how federal science funding survived within the highly controversial and costly American Recovery and Reinvestment Act of 2009 (ARRA).
The volatile and unpredictable nature of science policy lends itself well to the MSF, while the more static IAD is less useful to explain how and why the funds stayed in the bill. This is telling about the scope and adaptability of the two frameworks, where each may be better suited for different policy environments. The MSF being more appropriate for unstable and capricious policy issues and the IAD better matched for policy issues which have a somewhat more stable environment.

Tese de Doutoramento em Administração Pública, Especialidade em Administração e Políticas PúblicasA economia digital, fruto da fusão das tecnologias de informação e de comunicação, tem sido responsável por grandes ganhos de produtividade na nossa sociedade, ao mesmo tempo que impõe desafios aos governos nacionais, em particular na esfera tributária. Partindo do pressuposto de que a tributação é, em si mesma, uma importante política pública, este trabalho tem como objetivo central compreender o processo de agendamento e formulação das políticas públicas para a tributação da economia digital, através da aplicação de modelos de análise às iniciativas em curso no Brasil e na União Europeia (UE). Para que fosse possível o cumprimento do objetivo supramencionado, o esforço de pesquisa desdobrou-se em três frentes principais: (i) a caraterização da economia digital e dos seus impactos nas políticas fiscais; (ii) a análise das principais políticas públicas para a tributação digital em discussão e em implementação no Brasil e na União Europeia, bem como em alguns outros Estados selecionados, e (iii) a realização de dois estudos de caso, do Brasil e da União Europeia, procurando compreender os condicionantes do processo de formação de agenda para o tema, com o auxílio dos modelos teóricos dos Múltiplos Fluxos e do Equilíbrio Pontuado. O estudo dos novos modelos de negócio da economia digital mostrou que as suas características específicas, tais como a geração de valor a partir dos dados dos utilizadores e a capacidade de operar em mercados com consumidores à distância, exigem uma verdadeira reformulação do arcabouço tributário internacional. Entretanto, as políticas públicas para o tema no âmbito internacional têm sido marcadas pela polarização entre os Estados que sediam as grandes empresas digitais e aqueles que possuem os mercados consumidores nos quais estas atuam. Neste sentido, a União Europeia tem tido uma posição paradigmática em defesa de uma maior tributação dos negócios digitais nos Estados onde se encontram os consumidores. Já no Brasil, dono de um sistema tributário complexo e descentralizado, as principais medidas para a tributação digital têm sido marcadas pelo incrementalismo e pela sedimentação institucional, na forma da interpretação da legislação tributária vigente e da sua aplicação aos negócios digitais, o que gera instabilidade jurídica e disputas federativas. Por fim, o estudo do processo político de agendamento da tributação digital mostrou condicionantes diferentes para cada caso. Na Europa, a crise de 2008, que gerou políticas de austeridade e a necessidade de procura de novas bases tributárias, associada à frequente divulgação de escândalos fiscais por parte das grandes empresas digitais, criou o “humor nacional” de injustiça fiscal e permitiu o agendamento do tema na forma da proposta de imposto digital lançada pela Comissão Europeia em 2018. Neste caso, também contribuíram o processo de procura por arenas políticas dentro das instituições da UE, por parte dos Estados europeus com maiores mercados consumidores, e a falha na procura de consenso internacional, a cargo da OCDE, que criou uma “janela de políticas públicas” para a colocação da proposta europeia. Por outro lado, no Brasil, foi observado uma falta de diagnóstico para a problema que decorre, de entre outros fatores, do desfasamento dos efeitos da crise de 2008 no Estado e das crises político-económicas recentes, que impediram maiores debates sobre o tema, aliada a uma grande fragmentação institucional decorrente da própria estrutura federativa e da matriz tributária nacional. Além disso, o debate sobre uma reforma tributária geral no Estado, retomado em 2019 a partir de um novo mandato presidencial de cunho reformista, tem sido marcado pela “imagem política” da simplificação e diminuição da carga tributária, o que impede uma maior discussão sobre propostas de tributação específicas para o setor digital.
The digital economy, the result of the fusion of information and communication technologies, has been responsible for important productivity gains in our society, while imposing challenges on national governments, particularly in the taxation field. Based on the assumption that taxation is, in itself, an important public policy, this work has the central objective of understanding the agenda setting process and policy formulation for public policies for the taxation of the digital economy, through the application of analysis models to initiatives ongoing in Brazil and in the European Union (EU). In order to make it possible to achieve the aforementioned objective, the research effort unfolded on three main fronts: (i) the characterization of the digital economy and its impacts on fiscal policies; (ii) the analysis of the main public policies for digital taxation under discussion and being implemented in Brazil and in the European Union, as well as in some other selected States, and (iii) the realization of two case studies, with respect to Brazil and the European Union, seeking to understand the constraints of the agenda setting process for the theme, with the application of the theoretical models of Multiple Flows and Punctuated Equilibrium. The study of new business models in the digital economy has shown that their specific characteristics, such as the generation of value from user data and the ability to operate in markets with remote consumers, require a real reformulation of the international taxation framework. However, public policies for the topic at the international level have been marked by the polarization between States that host large digital companies and those that have the consumer markets in which they operate. In this sense, the European Union has taken a paradigmatic position in defense of greater taxation of digital businesses in States where consumers are located. In Brazil, which owns a complex and decentralized tax system, the main measures for digital taxation have been marked by incrementalism and institutional sedimentation, in the form of the interpretation of current tax legislation and its application to digital businesses, which creates legal instability and federative disputes. Finally, the study of the agenda setting process for digital taxation showed different determinants for each case. In Europe, the 2008 crisis, which generated austerity policies and the need to search for new tax bases, associated with the frequent disclosure of tax scandals by large digital companies, created the “national mood” of tax injustice and allowed the agenda setting for the theme in the form of the digital tax proposal launched by the European Commission in 2018. In this case, other factors that contributed to the agenda setting were the process of venue shopping within the EU institutions, by European countries with larger consumer markets, and the failure in the pursuit of international consensus, in charge of the OECD, which created a “policy window” for the placement of the European proposal. On the other hand, in Brazil, there is a lack of diagnosis for the problem that relates, among other factors, from the lag of the effects of the 2008 crisis in the State and from the recent political-economic crises, which prevented further debates on the topic, combined with a great institutional fragmentation resulting from the federative structure and from the national tax matrix. In addition, the debate on general tax reform in the State, resumed in 2019 as result of a new reformist presidential mandate, has been marked by the “policy image” of simplifying and reducing the tax burden, which prevents further discussion on specific tax proposals for the digital sector.

Full textAbstract:
L’objectif de cette thèse en science politique est d’analyser l’influence de l’Union européenne (UE) sur les politiques de santé électronique nationales, autrement appelées ‘politiques d’e-santé’. En effet, depuis plusieurs années, l’UE développe des instruments visant à favoriser l’introduction des technologies de l’information et de la communication dans l’organisation des soins, bien qu’elle ne dispose pas de compétences dans ce domaine. L’argument central de cette recherche est le suivant : les usages sélectifs et stratégiques des instruments européens sont le vecteur principal de l’Européanisation des politiques publiques nationales. Cette hypothèse est testée à l’aide d’une analyse comparative de trois cas : les politiques d’e-santé en France, en Autriche et en Irlande.Au travers des usages, l’Union européenne est susceptible d’affecter directement le contenu des politiques publiques, les jeux de pouvoirs des acteurs politiques et institutionnels, ou encore la hiérarchisation des problèmes de politique publique. Cette thèse montre que trois éléments sont nécessaires pour créer des conditions favorables au développement de multiples usages de l’UE : l’existence d’un intérêt des acteurs à puiser au sein de ressources externes au niveau national, une relation positive à l’Union européenne, et une structure suffisamment diversifiée des instruments européens. Si ces conditions sont remplies, l’influence de l’Union européenne peut se manifester à tous les stades de développement de la politique publique. Pour prendre en compte cette diversité empirique des usages, un modèle d’analyse des politiques publiques basé sur la théorie des courants multiples est proposé. Ce modèle permet de caractériser précisément l’influence causale de l’Union européenne dans les processus de construction des politiques publiques nationalesThe aim of this PhD thesis is to understand how the European Union (EU) may affect domestic electronic health (‘eHealth’) politics and policies despite its lack of competence in this area. Over the past years, the EU has supported the use of information and communication technologies within healthcare systems through the development of numerous instruments. The key argument of this research is that selective and strategic uses of European instruments by domestic actors are the core mechanisms of Europeanisation. This hypothesis is tested using a comparative analysis of eHealth policies in France, Austria and Ireland.Through actors ‘usage’, the EU is likely to affect the content of public policies, power games between policy actors, or the prioritisation of policy problems. This thesis shows that three conditions explain the appearance of various instances of EU usage at the domestic level: the presence of a strong interest for actors to use external resources in their political work, a positive relationship to the European level, and a diversified structure of European instruments. If these conditions are met, the EU influence is likely to occur at every stage of the policy development process. To take into account the empirical variety of EU usage, a new model based on the multiple streams framework is presented. This model allows for an accurate definition of EU causal influence in the domestic policy-making processes

Les Aliances Públiques Privades han constituït una estratègia adoptada pels governs per compartir responsabilitat, controlar costos i augmentar l'eficiència a través de la implementació de mecanismes de competència. L'educació no és una excepció, però les respostes han estat diferenciades entre països. Intentar comprendre com la gestió de les escoles surt de l'esfera de l'estat i passa a les mans dels privats, va ser el malnom d'aquesta tesi. A partir de l'enteniment que no n'hi ha prou a crear un context legislatiu favorable per garantir l'aplicació de les polítiques, s'ha intentat identificar que altres variables influencien la possibilitat d'establiment d'aquest tipus d'acords, que va ser mesurat pel nombre d'escoles gestionades per entitats privades, però pagades per l'estat
En aquest sentit, i partint de la Teoria dels Fluxos Múltiples quals destaca la interacció entre polítiques, problemes, actors polítics i emprenedors, es va desenvolupar un algoritme que permet determinar quines configuracions observables durant la fase d'adopció de polítiques que condueixen a un augment de possibilitat d'aplicació.
L'anàlisi qualitativa i quantitativa dels casos empírics mostra que diversos tipus d'associacions públic-privades s'han implementat bé a Anglaterra des dels anys 80, després d'una llarga caminada d'adaptació i perseverança. A Portugal s'han produït menys experiència, tots els quals apareixien les seves arrels en el desequilibri de la discussió entre la demanda i l'oferta, en el qual el sector privat es limita a reemplaçar temporalment l'oferta pública, el que porta a una reducció de la presència d'aquest tipus d'associació. Les diferències d'implementació verificades són el resultat de configuracions diferents en el moment de la legislació, atès que l'equilibri entre les diferents dimensions condiciona la possibilitat d'assolir els objectius.
Aquesta conclusió apunta al fet que és possible mitigar la ineficiència de la legislació si la configuració de les diferents variables propostes es considera durant la fase d'adopció de polítiques. Els punts febles de les diverses dimensions han de ser reconeguts i corregits.

Public-Private Partnerships have been a strategy adopted by governments to share responsibility with the private sector, control public spending and enhance efficiency through market competition. Education has been no exception to this trend, yet it happens differently across the countries. In this thesis, the aim was to understand how various parts of the education system have been transferred to private entities. The observation that encouraging legislation is far from being enough to warrant that schools move into the hands of private providers, implied that other variables might influence the possibility of policy establishment, here measured by the growth in the number of schools that are directed by private entities while paid by the state. Based on the Multiple Streams Framework variables, which emphasises the interaction of policy, problems, politics, and entrepreneurs, an algorithm was developed to reveal the configurations that, at the legislative moment, favour the establishment of policies. Qualitative and quantitative analysis of empirical cases show that the number of schools under Public-Private Partnership agreements increased substantially in England since the 80s, following a long path of adjustment and perseverance, while in Portugal the few experiences that subsist are strongly supported on the imbalance between demand and supply, as private providers are called for temporarily replacing the state. These different outcomes are a result of distinct configurations achieved at the time of legislation, as the equilibrium among the diverse policy dimensions influences the possibility of policy goal achievement. This conclusion points to the fact that legislation inefficiency can be mitigated if the required configuration is carefully assessed at the time of policy adoption, and the identification of weak points is recognised and corrected. Stakeholders perseverance, policy re-designing, active entrepreneurs and a favourable political scenario are crucial aspects for increasing the possibility of long-term policy acceptability.

The logic of green growth—both as issue framing and policy agenda—is compelling only if there is a political path to making it happen. This chapter considers green growth prospects in the United States from two perspectives. The first is the explanatory value of two theoretical models that have been influential in the field of policy studies: the multiple streams and advocacy coalition frameworks. The second is the conditions under which a long-term, durable transition to green growth may occur. These are to build a political coalition for green growth, deliver institutional reforms that enhance democracy, reduce economic inequality, and stress global action and interdependency. Only by linking ecology with economy in positive ways is there a practical path to living a good life on a finite earth.

Racism, sexism, homophobia, and low socioeconomic status (SES) have the potential to affect physical and mental health outcomes and treatment differentially. This chapter examines each of these sociocultural factors, guided by the assumption that an intersectionality analysis is valuable to conceptualizing the consequences of these categories of identity and diversity. The minority stress framework is used to consider the negative effect of carrying a marginalized identity. A review of the literature is presented, highlighting studies that incorporate the multiple and overlapping effects of racism, sexism, homophobia, and low SES to shape mental and physical health outcomes and treatment of individuals. Implications for mental and physical health research and practice are discussed.

This chapter contributes to the research and practice of creativity by increasing awareness of the inherently paradoxical nature of creativity, and offering strategies for managing the paradox. The authors’ framework delineates contradictory yet interrelated creativity outcomes, processes and identities of individuals, leaders, and groups. They highlight the paradox of creativity from multiple perspectives and suggest that when engaging in creativity, people experience paradoxical thoughts, processes, goals, identities, and perspectives. Creative people need to be generative and evaluative, flexible and persistent, passionate and disciplined, and learning and performance orientated. Drawing from related research on innovation management, attention control, and goal setting, we discuss strategies for achieving both novelty and usefulness including using paradoxical frames, task switching, pursuing contradictory goals, and gaining experience in different cultural contexts that stress different aspects of the creative process.

Developmental music therapy (DMT) is a model that underpins music therapy practice with multiple client groups. The resonances of DMT can be found whenever music therapists use any or all of their understanding of developmental stages, family context, and social and cultural frameworks to consider needs and interactions within individual or group music therapy. Music therapy training courses teach developmental theories, and therefore most practising music therapists use these theoretical perspectives in their interactions with clients. Thus chapter will show how developmental music therapy refers to three major theoretical orientations: (1) Theories of stress, coping, and adaption; (2) Human life span development, including stage models of development, and musical milestones of development; and (3) Ecological perspectives such as Bronfenbrenner’s bioecological model of development (Bronfenbrenner 1979). Boxill consistently termed her approach developmental music therapy (Boxill 1989). Therefore, this chapter provides an overview of Boxill’s writings and theoretical positioning within DMT.

Full textAbstract:
Abstract The challenge in the design of oxy-combustors for direct-fired supercritical CO2 (sCO2) cycles is in addressing disparate performance metrics and objectives. Key design parameters to consider include among others: injector design for mixing and flame stability, split of recycled CO2 diluent between injectors and cooling films, target flame temperatures to control non-condensable products, and strategies to inject the diluent CO2 for film cooling and thermal control. In order to support novel oxy-combustor designs, a high-fidelity yet numerically efficient modeling framework based on the CRUNCH CFD® flow solver is presented, featuring key physics-based sub-models relevant in this regime. For computational efficiency in modeling large kinetic sets, a flamelet/progress variable (FPV) based tabulatedchemistry approach is utilized featuring a three-stream extension to allow for the simulation of the CO2 film cooling stream in addition to the fuel and oxidizer streams. Finite-rate chemistry effects are modeled in terms of multiple progress variables for the primary flame as well as for slower-evolving chemical species such as NOx and SOx contaminants. Real fluid effects are modeled using advanced equations of states. The predictive capabilities of this computationally-tractable design support tool are demonstrated on a conceptual injector design for an oxy-combustor operating near 30 MPa. Simulations results provide quantitative feedback on the effectiveness of the film cooling as well as the level of contaminants (CO, NO, and N) in the exhaust due to impurities entering from the injectors. These results indicate that this framework would be a useful tool for refining and optimizing the oxy-combustor designs as well as risk mitigation analyses.

Full textAbstract:
Prediction of popularity has profound impact for social media, since it offers opportunities to reveal individual preference and public attention from evolutionary social systems. Previous research, although achieves promising results, neglects one distinctive characteristic of social data, i.e., sequentiality. For example, the popularity of online content is generated over time with sequential post streams of social media. To investigate the sequential prediction of popularity, we propose a novel prediction framework called Deep Temporal Context Networks (DTCN) by incorporating both temporal context and temporal attention into account. Our DTCN contains three main components, from embedding, learning to predicting. With a joint embedding network, we obtain a unified deep representation of multi-modal user-post data in a common embedding space. Then, based on the embedded data sequence over time, temporal context learning attempts to recurrently learn two adaptive temporal contexts for sequential popularity. Finally, a novel temporal attention is designed to predict new popularity (the popularity of a new user-post pair) with temporal coherence across multiple time-scales. Experiments on our released image dataset with about 600K Flickr photos demonstrate that DTCN outperforms state-of-the-art deep prediction algorithms, with an average of 21.51% relative performance improvement in the popularity prediction (Spearman Ranking Correlation).

Drawing an inspiration from behavioral studies of human decision making, we propose here a general parametric framework for a reinforcement learning problem, which extends the standard Q-learning approach to incorporate a two-stream framework of reward processing with biases biologically associated with several neurological and psychiatric conditions, including Parkinson's and Alzheimer's diseases, attention-deficit/hyperactivity disorder (ADHD), addiction, and chronic pain. For AI community, the development of agents that react differently to different types of rewards can enable us to understand a wide spectrum of multi-agent interactions in complex real-world socioeconomic systems. Moreover, from the behavioral modeling perspective, our parametric framework can be viewed as a first step towards a unifying computational model capturing reward processing abnormalities across multiple mental conditions and user preferences in long-term recommendation systems.

Abstract The residual useful lifetime prediction of complex engineering systems operating under dynamic multi-operational conditions is crucial yet challenging. One of the key challenges is that sensing signals consist of both degradation information that resulted from the physical deterioration of the system and amplitude jumps due to the switch of operational conditions. To accurately predict the failure times, we need to separate the degradation information from sensing signals and exclude jumps. Another challenge stems from the fact that complex engineering systems are typically monitored by multiple sensors that generate multi-stream sensing signals but not all the signals are informative for failure time prediction. Therefore, a systematical sensor selection method needs to be developed to identify informative sensors. The third challenge is that signals from the informative sensors are high-dimensional and may provide redundant information. As a result, a data fusion method is needed to fuse the multi-stream signals from the informative sensors. To address the aforementioned challenges, this paper focuses on developing a prognostic framework for systems that operate under dynamic multiple operational conditions. The framework will first extract the degradation signal from each sensor by removing the jump information resulted from the change of operational conditions. Next, informative sensors are selected using a sensor selection method. Finally, the degradation signals from the selected sensors are fused to predict the failure time of a partially degraded system. The effectiveness of the proposed prognostic framework is validated using a degradation data set of aircraft turbofan engines from NASA repository.
