„El mole rachmim” / „El Male Rachamim”: Gomulicki, Tuwim, Linke
No full textAutorka porównuje nawiązania do żydowskiej modlitwy El Male Rachamim (hebr. ‘Boże Pełen Miłosierdzia’): wiersz El mole rachmim Wiktora Gomulickiego, Ghetto Juliana Tuwima z Notatnika poetyckiego i powojenny rysunek Bronisława Linkego El mole rachmim. Zachodzą między nimi relacje intertekstualne, intersemiotyczne i interpersonalne (Tuwim umieścił utwór Gomulickiego w Księdze wierszy polskich XIX wieku; Linke ilustrował Bal w Operze; zapiska Ghetto zapowiada tekst My, Żydzi polscy). Co dzieje się z motywem wędrującym przez kody kulturowe i znakowe? Czy cezura Zagłady istotnie go odmienia?The author compares the references to the Jewish prayer El Male Rachamim (Hebrew for ‘God Full of Mercy’): El Male Rachmim by Wiktor Gomulicki, Julian Tuwim’s Ghetto from Notatnik poetycki and a post-war drawing by Bronisław Linke El male rachmim. There are intertext, intersemiotic and interpersonal relations happening between them (Tuwim included Gomulicki’s work in Księga wierszy polskich XIX wieku [A Book of Polish Verses of the 19th Century]; Linke illustrated Bal w Operze [Ball at the Opera]; a note in Ghetto announces text My, Żydzi polscy [We, Polish Jews]). What is happening with the motif wandering through cultural and character codes? Does the turning point of the Extinction indeed change it

Cost-utility of transcatheter aortic valve implantation for inoperable patients with severe aortic stenosis treated by medical management: a UK cost-utility analysis based on patient-level data from the ADVANCE study.
No full textOBJECTIVE: To use patient-level data from the ADVANCE study to evaluate the cost-effectiveness of transcatheter aortic valve implantation (TAVI) compared to medical management (MM) in patients with severe aortic stenosis from the perspective of the UK NHS.
METHODS: A published decision-analytic model was adapted to include information on TAVI from the ADVANCE study. Patient-level data informed the choice as well as the form of mathematical functions that were used to model all-cause mortality, health-related quality of life and hospitalisations. TAVI-related resource use protocols were based on the ADVANCE study. MM was modelled on publicly available information from the PARTNER-B study. The outcome measures were incremental cost-effectiveness ratios (ICERs) estimated at a range of time horizons with benefits expressed as quality-adjusted life-years (QALY). Extensive sensitivity/subgroup analyses were undertaken to explore the impact of uncertainty in key clinical areas.
RESULTS: Using a 5-year time horizon, the ICER for the comparison of all ADVANCE to all PARTNER-B patients was £13 943 per QALY gained. For the subset of ADVANCE patients classified as high risk (Logistic EuroSCORE >20%) the ICER was £17 718 per QALY gained). The ICER was below £30 000 per QALY gained in all sensitivity analyses relating to choice of MM data source and alternative modelling approaches for key parameters. When the time horizon was extended to 10 years, all ICERs generated in all analyses were below £20 000 per QALY gained.
CONCLUSION: TAVI is highly likely to be a cost-effective treatment for patients with severe aortic stenosis

The analogue of grad-div stabilization in DG methods for incompressible flows: Limiting behavior and extension to tensor-product meshes
No full textSchroeder, Philipp W./0000-0001-7644-4693WOS: 000442638700037grad-div stabilization is a classical remedy in conforming mixed finite element methods for incompressible flow problems, for mitigating velocity errors that are sometimes called poor mass conservation. Such errors arise due to the relaxation of the divergence constraint in classical mixed methods, and are excited whenever the spatial discretization has to deal with comparably large and complicated pressures. In this contribution, an analogue of grad-div stabilization for Discontinuous Galerkin methods is studied. Here, the key is the penalization of the jumps of the normal velocities over facets of the triangulation, which controls the measure-valued part of the distributional divergence of the discrete velocity solution. Our contribution is twofold: first, we characterize the limit for arbitrarily large penalization parameters, which shows that the stabilized nonconforming Discontinuous Galerkin methods remain robust and accurate in this limit; second, we extend these ideas to the case of non-simplicial meshes; here, broken grad-div stabilization must be used in addition to the normal velocity jump penalization, in order to get the desired pressure robustness effect. The analysis is performed for the Stokes equations, and more complex flows and Crouzeix-Raviart elements are considered in numerical examples that also show the relevance of the theory in practical settings.

Development of a Psychologically Enhanced Interactive Online Intervention for Hazardous Drinking
No full textAims: The content of novel interventions is often not well specified. We provide a detailed account of the rationale for and redevelopment of an Internet resource for hazardous drinkers-Down Your Drink (DYD) (www.downyourdrink.org.uk). Development Work: An iterative process blended literature reviews of Internet interventions for health conditions and brief treatments for alcohol problems, feedback from users of the original site and from users panels, and completion of a series of developmental tasks. Intervention: The detailed structure and content of the new version of the website is presented. This permits an appreciation of the intended interaction between the user and the intervention, and emphasizes both the freedom of choice available to the user to access diverse material for personal benefit and the value of a clear organizational structure. Conclusions: Presentation of detailed information on the theoretical underpinning, content and structure of an intervention makes it easier to interpret the results of any evaluation and is likely to be of use to those developing other online interventions for alcohol or other health behaviours

Women in German politics: still jobs for the boys?
No full textToday the proportion of German politicians who are female is at an all time high. This has largely been achieved via quotas and most of the main parties now operate some kind of quota system. But have quantitative improvements in female representation in been matched by qualitative improvements? This article seeks to answer this question by looking not only at the number of women in parliaments and other collective bodies, but also in the highest echelons of power. It outlines each party's policies regarding the promotion of women and the factors which enhance or hamper their impact. A brief comparison of female political representation in eastern and western Germany is also provided. The author argues that measures such as quotas have increased the number of female German politicians but still do not guarantee them equal access to positions of real power. Furthermore, the incorporation of pro-equality principles into party statutes has not automatically led to their assimilation into party cultures, especially in the case of well-established parties which only recently addressed the gender imbalance in their ranks
Integrated conservation planning for river-wetland mosaics
No full textWetlands are highly productive and biodiverse ecosystems and provide many ecosystem services for humans. They are a key component of the natural hydrological cycle and are involved in important biophysical processes, such as the exchange of sediments, nutrients and organisms which influence water quality and functional integrity of rivers. Owing to their high productivity, fertile soils, and importance for water provision, many of the world’s wetlands have a long history of human occupation and intensive use. As a consequence, extensive degradation and modification of wetland ecosystems by human activities has occurred worldwide.
In seasonal wetlands, the timing and duration of soil saturation and inundation are the main determinants of geomorphological and ecological characteristics that give rise to a great variety of ecosystem types. Although the ecological functioning of seasonal wetlands relies on this strong temporal driver, wetland conservation decisions often are based on static maps of wetland boundaries that fail to depict their dynamic hydrological variability and connectivity.
Another challenge in wetland conservation is accounting for multiple dimensions of wetland connectivity in the riverine landscape. For example, the ecological integrity of large floodplain rivers, such as the Amazon River system, depends on the maintenance of a diversity of waterbodies with variable degrees of connectivity between themselves and with the main river channel. Lack of adequate frameworks in wetland conservation planning to account for these different sources of connectivity can compromise the long-term persistence and integrity of wetlands in the landscape. This is a critical issue because human activities such as land use change, levee construction and flow regime alterations can lead to the disruption of connectivity, thus greatly affecting wetlands downstream and compromising their ecological integrity and provision of ecosystem services.
The overall objective of this thesis is to develop a new framework of systematic conservation planning for river-floodplain ecosystems that adequately accounts for the multidimensional connectivity of wetlands in riverine landscapes. To achieve that, I have combined the use of remote sensing tools at multiple scales with statistical modelling and spatial planning to address three main issues in wetland conservation: (1) the lack of comprehensive assessments to determine conservation status of the world’s wetlands, (2) the limitations of representing wetland seasonality in traditional static maps that often delineate wetland boundaries based on minimum or maximum extents, and (3) the lack of adequate spatial frameworks in systematic conservation planning to deal with wetland connectivity in the riverine landscape.
To address the first issue, I developed a global-scale portrait of the threats and protection status of the world’s inland wetlands. This was achieved by combining a global map of inundation extent derived from satellite images with data on threats from human influence and on protected areas. Inland wetlands represent only ~6% of the world’s land surface, and about 89% of these areas have no formal protection (as defined by protected areas IUCN I-VI and Ramsar sites). Wetland protection was variable across the world, ranging from 20% in Central and 18% in South America to only 8% in Asia. Particularly high human influence was found in Asia, which contains the largest wetland area of the world. High human influence was observed in wetlands even when they are within protected areas. This demonstrated that terrestrial protected areas do not always adequately protect wetland ecosystems and underscores the urgent need for more effective conservation measures worldwide.
To tackle the second issue, I undertook a hydrological classification of the Amazon wetlands according to the timing and duration of inundation. The classification was based on remotely sensed monthly inundation maps, and also investigated how precipitation regimes affect wetland distribution and hydrological dynamics. Permanently inundated wetlands accounted for the largest area and were mainly floodplains located in the lowlands of the catchment. Seasonally inundated wetlands varied greatly in duration of inundation over the course of the year, ranging from one to nine months. Distinct seasonal timing was detected among large wetland complexes, reflecting rainfall regimes as well as time lags for recession and drying. For example, inundation in the extensive Llanos the Moxos region of the southern Amazon was protracted and lasted well after the rainy season, compared to the Roraima region of the northern Amazon where inundation was shorter and tracked the rainy season. This integration of inundation dynamics into wetland classification captures regional differences in timing and duration of inundation in major wetlands of the basin that should be considered in conservation planning and other ecological applications.
Finally, I developed a new framework in systematic conservation planning to account for the multidimensional connectivity of floodplain river ecosystems and provide more adequate protection of wetlands, and applied this to the entire Amazon basin. Accounting for both within-floodplain and longitudinal river connectivity in the riverine landscape, the new spatial framework combines two types of planning units – wetland hexagons and subcatchments – which were connected using two distance-based approaches. Four prioritization scenarios were tested comparing only within-floodplain connectivity versus integrated within-floodplain and upstream connectivity and resulted in varying levels of reduced impact. When only considering within-floodplain connectivity, propagation of impacts from the surroundings and upstream catchment was ignored. In contrast, the scenario that included both within-floodplain and longitudinal river connectivity agglomerated subcatchments around the priority wetlands, achieving catchment integration that efficiently reduced impact.
This thesis contributes to the field of wetland conservation by integrating cutting edge data science with novel planning methods. It highlights the conservation status of inland wetlands and quantifies global and continental threat patterns. The innovative classification approach that spatially represents seasonal patterns in wetland inundation can be used to explore the role of seasonality on the ecological characteristics and functions of different wetlands complexes. It represents an important step towards including temporal dynamics in wetland conservation planning and management. Furthermore, including the multidimensional connectivity of wetlands in a comprehensive spatial framework can offer more ecologically meaningful protection to floodplains. This is crucial to plan for safeguarding wetland ecosystem functions at the landscape context. Finally, the use of global remotely sensed data sets make all approaches presented here readily adaptable for use in other regions of the world.Thesis (PhD Doctorate)Doctor of Philosophy (PhD)School of Environment and ScScience, Environment, Engineering and TechnologyFull Tex
