QUESTIONS UNDER STUDY To improve the response of deteriorating patients during their hospital stay, the University Hospital Bern has introduced a Medical Emergency Team (MET). Aim of this retrospective cohort study is to review the preceding factors, patient characteristics, process parameters and their correlation to patient outcomes of MET calls since the introduction of the team. METHODS Data on patient characteristics, parameters related to MET activation and intervention and patient outcomes were evaluated. A Vital Sign Score (VSS), which is defined as the sum of the occurrence of each vital sign abnormalities, was calculated for all physiological parameters pre MET event, during event and correlation with hospital outcomes. RESULTS A total of 1,628 MET calls in 1,317 patients occurred; 262 (19.9%) of patients with MET calls during their hospital stay died. The VSS pre MET event (odds ratio [OR] 1.78, 95% confidence interval [CI] 1.50-2.13; AUROC 0.63; all p <0.0001) and during the MET call (OR 1.60, 95% CI 1.41-1.83; AUROC 0.62; all p <0.0001) were significantly correlated to patient outcomes. A significant increase in MET calls from 5.2 to 16.5 per 1000 hospital admissions (p <0.0001) and a decrease in cardiac arrest calls in the MET perimeter from 1.6 in 2008 to 0.8 per 1000 admissions was observed during the study period (p = 0.014). CONCLUSIONS The VSS is a significant predictor of mortality in patients assessed by the MET. Increasing MET utilisation coincided with a decrease in cardiac arrest calls in the MET perimeter.

BACKGROUND Panic disorder is characterised by the presence of recurrent unexpected panic attacks, discrete periods of fear or anxiety that have a rapid onset and include symptoms such as racing heart, chest pain, sweating and shaking. Panic disorder is common in the general population, with a lifetime prevalence of 1% to 4%. A previous Cochrane meta-analysis suggested that psychological therapy (either alone or combined with pharmacotherapy) can be chosen as a first-line treatment for panic disorder with or without agoraphobia. However, it is not yet clear whether certain psychological therapies can be considered superior to others. In order to answer this question, in this review we performed a network meta-analysis (NMA), in which we compared eight different forms of psychological therapy and three forms of a control condition. OBJECTIVES To assess the comparative efficacy and acceptability of different psychological therapies and different control conditions for panic disorder, with or without agoraphobia, in adults. SEARCH METHODS We conducted the main searches in the CCDANCTR electronic databases (studies and references registers), all years to 16 March 2015. We conducted complementary searches in PubMed and trials registries. Supplementary searches included reference lists of included studies, citation indexes, personal communication to the authors of all included studies and grey literature searches in OpenSIGLE. We applied no restrictions on date, language or publication status. SELECTION CRITERIA We included all relevant randomised controlled trials (RCTs) focusing on adults with a formal diagnosis of panic disorder with or without agoraphobia. We considered the following psychological therapies: psychoeducation (PE), supportive psychotherapy (SP), physiological therapies (PT), behaviour therapy (BT), cognitive therapy (CT), cognitive behaviour therapy (CBT), third-wave CBT (3W) and psychodynamic therapies (PD). We included both individual and group formats. Therapies had to be administered face-to-face. The comparator interventions considered for this review were: no treatment (NT), wait list (WL) and attention/psychological placebo (APP). For this review we considered four short-term (ST) outcomes (ST-remission, ST-response, ST-dropouts, ST-improvement on a continuous scale) and one long-term (LT) outcome (LT-remission/response). DATA COLLECTION AND ANALYSIS As a first step, we conducted a systematic search of all relevant papers according to the inclusion criteria. For each outcome, we then constructed a treatment network in order to clarify the extent to which each type of therapy and each comparison had been investigated in the available literature. Then, for each available comparison, we conducted a random-effects meta-analysis. Subsequently, we performed a network meta-analysis in order to synthesise the available direct evidence with indirect evidence, and to obtain an overall effect size estimate for each possible pair of therapies in the network. Finally, we calculated a probabilistic ranking of the different psychological therapies and control conditions for each outcome. MAIN RESULTS We identified 1432 references; after screening, we included 60 studies in the final qualitative analyses. Among these, 54 (including 3021 patients) were also included in the quantitative analyses. With respect to the analyses for the first of our primary outcomes, (short-term remission), the most studied of the included psychological therapies was CBT (32 studies), followed by BT (12 studies), PT (10 studies), CT (three studies), SP (three studies) and PD (two studies).The quality of the evidence for the entire network was found to be low for all outcomes. The quality of the evidence for CBT vs NT, CBT vs SP and CBT vs PD was low to very low, depending on the outcome. The majority of the included studies were at unclear risk of bias with regard to the randomisation process. We found almost half of the included studies to be at high risk of attrition bias and detection bias. We also found selective outcome reporting bias to be present and we strongly suspected publication bias. Finally, we found almost half of the included studies to be at high risk of researcher allegiance bias.Overall the networks appeared to be well connected, but were generally underpowered to detect any important disagreement between direct and indirect evidence. The results showed the superiority of psychological therapies over the WL condition, although this finding was amplified by evident small study effects (SSE). The NMAs for ST-remission, ST-response and ST-improvement on a continuous scale showed well-replicated evidence in favour of CBT, as well as some sparse but relevant evidence in favour of PD and SP, over other therapies. In terms of ST-dropouts, PD and 3W showed better tolerability over other psychological therapies in the short term. In the long term, CBT and PD showed the highest level of remission/response, suggesting that the effects of these two treatments may be more stable with respect to other psychological therapies. However, all the mentioned differences among active treatments must be interpreted while taking into account that in most cases the effect sizes were small and/or results were imprecise. AUTHORS' CONCLUSIONS There is no high-quality, unequivocal evidence to support one psychological therapy over the others for the treatment of panic disorder with or without agoraphobia in adults. However, the results show that CBT - the most extensively studied among the included psychological therapies - was often superior to other therapies, although the effect size was small and the level of precision was often insufficient or clinically irrelevant. In the only two studies available that explored PD, this treatment showed promising results, although further research is needed in order to better explore the relative efficacy of PD with respect to CBT. Furthermore, PD appeared to be the best tolerated (in terms of ST-dropouts) among psychological treatments. Unexpectedly, we found some evidence in support of the possible viability of non-specific supportive psychotherapy for the treatment of panic disorder; however, the results concerning SP should be interpreted cautiously because of the sparsity of evidence regarding this treatment and, as in the case of PD, further research is needed to explore this issue. Behaviour therapy did not appear to be a valid alternative to CBT as a first-line treatment for patients with panic disorder with or without agoraphobia.

This paper presents the 2005 Miracle’s team approach to the Ad-Hoc Information Retrieval tasks. The goal for the experiments this year was twofold: to continue testing the effect of combination approaches on information retrieval tasks, and improving our basic processing and indexing tools, adapting them to new languages with strange encoding schemes. The starting point was a set of basic components: stemming, transforming, filtering, proper nouns extraction, paragraph extraction, and pseudo-relevance feedback. Some of these basic components were used in different combinations and order of application for document indexing and for query processing. Second-order combinations were also tested, by averaging or selective combination of the documents retrieved by different approaches for a particular query. In the multilingual track, we concentrated our work on the merging process of the results of monolingual runs to get the overall multilingual result, relying on available translations. In both cross-lingual tracks, we have used available translation resources, and in some cases we have used a combination approach.

Autonomous systems refer to systems capable of operating in a real world environment without any form of external control for extended periods of time. Autonomy is a desired goal for every system as it improves its performance, safety and profit. Ontologies are a way to conceptualize the knowledge of a specific domain. In this paper an ontology for the description of autonomous systems as well as for its development (engineering) is presented and applied to a process. This ontology is intended to be applied and used to generate final applications following a model driven methodology.

Abstract?Background: There is no globally accepted open source software development process to define how open source software is developed in practice. A process description is important for coordinating all the software development activities involving both people and technology. Aim: The research question that this study sets out to answer is: What activities do open source software process models contain? The activity groups on which it focuses are Concept Exploration, Software Requirements, Design, Maintenance and Evaluation. Method: We conduct a systematic mapping study (SMS). A SMS is a form of systematic literature review that aims to identify and classify available research papers concerning a particular issue. Results: We located a total of 29 primary studies, which we categorized by the open source software project that they examine and by activity types (Concept Exploration, Software Requirements, Design, Maintenance and Evaluation). The activities present in most of the open source software development processes were Execute Tests and Conduct Reviews, which belong to the Evaluation activities group. Maintenance is the only group that has primary studies addressing all the activities that it contains. Conclusions: The primary studies located by the SMS are the starting point for analyzing the open source software development process and proposing a process model for this community. The papers in our paper pool that describe a specific open source software project provide more regarding our research question than the papers that talk about open source software development without referring to a specific open source software project.

Scientific missions constitute fundamental cornerstones of space agencies such as ESA and NASA. Modern astronomy could not be understood without the data provided by these missions. Scientists need to design very carefully onboard instruments. Payloads have to survive the crucial launch moment and later perform well in the really harsh space environ-ment. It is very important that the instrument conceptual idea can be engineered to sustain all those loads

Enabling Subject Matter Experts (SMEs) to formulate knowledge without the intervention of Knowledge Engineers (KEs) requires providing SMEs with methods and tools that abstract the underlying knowledge representation and allow them to focus on modeling activities. Bridging the gap between SME-authored models and their representation is challenging, especially in the case of complex knowledge types like processes, where aspects like frame management, data, and control flow need to be addressed. In this paper, we describe how SME-authored process models can be provided with an operational semantics and grounded in a knowledge representation language like F-logic in order to support process-related reasoning. The main results of this work include a formalism for process representation and a mechanism for automatically translating process diagrams into executable code following such formalism. From all the process models authored by SMEs during evaluation 82% were well-formed, all of which executed correctly. Additionally, the two optimizations applied to the code generation mechanism produced a performance improvement at reasoning time of 25% and 30% with respect to the base case, respectively.

The paper shows the design process of Nagele, a Dutch modernist agrarian settlement designed during the Post-Second World War period by the internationally recognized group of architects De 8 en Opbouw: Rietveld, Van Eesteren, Merkelbach, van Eyck, Bakema, Stam, Ruys, etc. It is located in the Noordoostpolder (NOP), in the Flevoland province, which was entirely reclaimed from the sea. The country planning of the Noodoostpolder reveals a high rationalization in the disposal of roads, canals, cities, agrarian land and forests, which can be an inspiration for the cities of today. The configurational elements of Nagele must be understood in terms of their relationship to the overall system of the polder. Important territorial principles in structure, form and landscape can be seen in the project of Nagele. This relationship is an additional example of the continuing transformation that the entire length and breadth of The Netherlands in subjected to. The research developed to date reveals a plan which shows the evolution of functionalistic paradigm at the CIAM postwar congresses. The particular case of Nagele points to the incorporation of human scale, green design and social co-existence. The source of these theories mainly came from Aldo van Eyck, who played an important role during the second phase of design. The research will be developed analyzing his drawings and texts and will show the way his theories appear in the project. Can Nagele be a materialization of Van Eyck¿s ideas? Nagele constitutes one of the most outstanding contributions to modern urban planning as far as both urbanism and landscape, are at the service of human well-being. Not only were urban independently designed parts, but their relationships also formed a perfect urban whole.

Fluorescently labeled myosin moved and accumulated circumferentially in the equatorial region of dividing Dictyostelium cells within a time course of 4 min, followed by contraction of the contractile ring. To investigate the mechanism of this transport process, we have expressed three mutant myosins that cannot hydrolyze ATP in myosin null cells. Immunofluorescence staining showed that these mutant myosins were also correctly transported to the equatorial region, although no contraction followed. The rates of transport, measured using green fluorescent protein-fused myosins, were indistinguishable between wild-type and mutant myosins. These observations demonstrate that myosin is passively transported toward the equatorial region and incorporated into the forming contractile ring without its own motor activity.

Structuralism is a theory of U.S. constitutional adjudication according to which courts should seek to improve the decision-making process of the political branches of government so as to render it more democratic.1 In words of John Hart Ely, courts should exercise their judicial-review powers as a ‘representation-reinforcing’ mechanism.2 Structuralism advocates that courts must eliminate the elements of the political decision-making process that are at odds with the structure set out by the authors of the U.S. Constitution. The advantage of this approach, U.S. scholars posit, lies in the fact that it does not require courts to second-guess the policy decisions adopted by the political branches of government. Instead, they limit themselves to enforcing the constitutional structure within which those decisions must be adopted. Of course, this theory of constitutional adjudication, like all theories, has its shortcomings. For example, detractors of structuralism argue that it is difficult, if not impossible, to draw the dividing line between ‘substantive’ and ‘structural’ matters.3 In particular, they claim that, when identifying the ‘structure’ set out by the authors of the U.S. Constitution, courts necessarily base their determinations not on purely structural principles, but on a set of substantive values, evaluating concepts such as democracy, liberty and equality. 4 Without claiming that structuralism should be embraced by the ECJ as the leading theory of judicial review, the purpose of my contribution is to explore how recent case-law reveals that the ECJ has also striven to develop guiding principles which aim to improve the way in which the political institutions of the EU adopt their decisions. In those cases, the ECJ decided not to second-guess the appropriateness of the policy choices made by the EU legislator. Instead, it preferred to examine whether, in reaching an outcome, the EU political institutions had followed the procedural steps mandated by the authors of the Treaties. Stated simply, I argue that judicial deference in relation to ‘substantive outcomes’ has been counterbalanced by a strict ‘process review’. To that effect, I would like to discuss three recent rulings of the ECJ, delivered after the entry into force of the Treaty of Lisbon, where an EU policy measure was challenged indirectly, i.e. via the preliminary reference procedure, namely Vodafone, Volker und Markus Schecke and Test-Achats.5 Whilst in the former case the ECJ ruled that the questions raised by the referring court disclosed no factor of such a kind as to affect the validity of the challenged act, in the latter cases the challenged provisions of an EU act were declared invalid.

This paper aims to identify the extent to which the non-promise of membership of the European Union (EU) precludes the motivation of Ukraine as European Neighbourhood Policy country to adopt EU policies in the field of market access, namely technical standards and regulations. Its approximation approach is compared to the fast-tracked accession of Slovakia, which was driven by a clear-cut membership promise. Furthermore, the paper elaborates whether the conclusion of an Association Agreement between the EU and Ukraine, including a Deep and Comprehensive Free Trade Agreement, provides sufficient incentives for Ukraine to continue reforming its quality infrastructure in order to gain access to the Single European Market. Finally, scenarios of possible developments of EU-Ukraine relations are deliberated in the context of the EU-Ukraine-Russia triangle. The paper argues that market access provides sufficient stimulus for third countries to adhere to EU technical standards – even in the absence of a clear and credible promise of future EU membership. Yet, in the case of Ukraine, the country’s relations with Russia appear to compete with its EU approximation process, resulting for the time being in Ukraine attempting to pursue a balanced dual cooperation with both the EU and Russia.

The most straightforward European single energy market design would entail a European system operator regulated by a single European regulator. This would ensure the predictable development of rules for the entire EU, significantly reducing regulatory uncertainty for electricity sector investments. But such a first-best market design is unlikely to be politically realistic in the European context for three reasons. First, the necessary changes compared to the current situation are substantial and would produce significant redistributive effects. Second, a European solution would deprive member states of the ability to manage their energy systems nationally. And third, a single European solution might fall short of being well-tailored to consumers’ preferences, which differ substantially across the EU. To nevertheless reap significant benefits from an integrated European electricity market, we propose the following blueprint: First, we suggest adding a European system-management layer to complement national operation centres and help them to better exchange information about the status of the system, expected changes and planned modifications. The ultimate aim should be to transfer the day-to-day responsibility for the safe and economic operation of the system to the European control centre. To further increase efficiency, electricity prices should be allowed to differ between all network points between and within countries. This would enable throughput of electricity through national and international lines to be safely increased without any major investments in infrastructure. Second, to ensure the consistency of national network plans and to ensure that they contribute to providing the infrastructure for a functioning single market, the role of the European ten year network development plan (TYNDP) needs to be upgraded by obliging national regulators to only approve projects planned at European level unless they can prove that deviations are beneficial. This boosted role of the TYNDP would need to be underpinned by resolving the issues of conflicting interests and information asymmetry. Therefore, the network planning process should be opened to all affected stakeholders (generators, network owners and operators, consumers, residents and others) and enable the European Agency for the Cooperation of Energy Regulators (ACER) to act as a welfare-maximising referee. An ultimate political decision by the European Parliament on the entire plan will open a negotiation process around selecting alternatives and agreeing compensation. This ensures that all stakeholders have an interest in guaranteeing a certain degree of balance of interest in the earlier stages. In fact, transparent planning, early stakeholder involvement and democratic legitimisation are well suited for minimising as much as possible local opposition to new lines. Third, sharing the cost of network investments in Europe is a critical issue. One reason is that so far even the most sophisticated models have been unable to identify the individual long-term net benefit in an uncertain environment. A workable compromise to finance new network investments would consist of three components: (i) all easily attributable cost should be levied on the responsible party; (ii) all network users that sit at nodes that are expected to receive more imports through a line extension should be obliged to pay a share of the line extension cost through their network charges; (iii) the rest of the cost is socialised to all consumers. Such a cost-distribution scheme will involve some intra-European redistribution from the well-developed countries (infrastructure-wise) to those that are catching up. However, such a scheme would perform this redistribution in a much more efficient way than the Connecting Europe Facility’s ad-hoc disbursements to politically chosen projects, because it would provide the infrastructure that is really needed.

A key element of Russia’s policy towards the new government of Ukraine concerns demands for a constitutional reform that would transform the country from a unitary into a federal state in a way that would considerably privilege the eastern and southern regions. Such a change to Ukraine’s administrative system would enable Moscow to put pressure on Ukraine’s central government via the regions. In order to achieve its objectives, Russia has been pressuring Kyiv to establish a constitutional assembly in a form that would guarantee the endorsement of solutions dictated by Russia. In other words, Russia has been demanding, in what is practically an ultimatum, that Ukraine give up one of the fundamental sovereign rights of a state, the right to freely determine its system of government. Transforming Ukraine into a federal state is an unacceptable idea, primarily because the intention behind Russia’s demands is to undermine Ukraine’s sovereignty, both through the content of the proposed changes and the way in which they are to be implemented. However, keeping in place the current, centralist model of state governance is not a feasible alternative. Ukraine will have to grant its regions broad self-governance powers, including the power to hold local referendums, and to transfer a considerable portion of the prerogatives currently held by the state to the local self-governments, along with adequate financial resources. That is because decentralisation along these lines is the only way forward towards a modern democracy in Ukraine. Russia’s policy has forced Kyiv to undertake legislative work on constitutional reform as a matter of urgency, rather than waiting until a new parliament is elected in which the new, post-Maidan balance of political power will be reflected, as political logic would require. The first draft of the constitutional amendments (of which no details are known at this stage) is to be presented in mid-May, and is expected to come into force in early autumn. However, whether these plans can be put into practice depends on further developments in the eastern part of Ukraine, because (among other reasons) if a state of emergency is introduced, the constitutional amendment process will have to be suspended.
