Quo vadis? How to measure the quality of local and regional development processes?

Today most activities which seem to be sound, cosy and helpful - or sometimes simply useful - are called ?sustainable'. Of course the requirements for measuring sustainability increased rapidly. Many different systems of indicators and conflicting opinions about the adequate approach characterise the present situation. Nevertheless we add another system with an specific approach to evaluate processes of local and regional development. In our opinion it is able notably to refer to the quality of the concept of sustainability. The basic system is threefold and bears analogy to the model of total quality management. We distinguish between: · The assessment of projects with respect to material, procedural and ethical implications. The conceptual framework is translated into an evaluation checklist to systematise the discussion of the character and general impact of a given project or programme. The methodology of this section has been presented at the 39th ERSA Congress 1999 in Dublin even and until now has been applied in different fields. · The assessment of development processes in terms of organisation, methodology, contents and legal demands. This section will be the main part of our presentation. · And the assessment of the state of the region which actually is a 'work in progress'. It will combine elements of 'top-down indicators, deduced from the international and national discussion of the CSD-scheme, with elements of regional specific indicators based on a bottom-up approach which defines regional specific goals of development according to a transdisciplinary approach of how to experience the local and regional space. Our methodology is based on self-evaluation and it can come into operation at an early stage accompanying the activities over the whole life cycle. The assessment of development processes is to be done from the local and regional actors for themselves, accompanied by scientific experts. It depends on four principles: · The people concerned are the experts. They get involved in learning processes. · The focus of the assessment is on credibility and transparency. · Development processes need a minimum of quality. The standard is fixed. · The quality management can be used in a flexible way to allow the assessment of different processes according to the communities main focus. The whole project of quality management is closely coupled with the regional Agenda 21 in the Lake of Constance- region as it has been shown eat the 40th ERSA Congress 2000 in Barcelona. Together with the network of 13 regional contact points in Switzerland, Austria, Germany and the Principality of Liechtenstein the different sections has been discussed and field-tested. 437 words Key words: sustainability, Agenda 21, quality management, development processes, transdisciplinarity

Comparison among different scoring systems in predicting procedural success and long-term outcomes after percutaneous coronary intervention in patients with chronic total coronary artery occlusions

Publisher Copyright: © 2019 by the authors. Licensee MDPI, Basel, Switzerland.Background and objectives: Different scoring systems are used to stratify patients with chronic total coronary artery occlusions (CTO) according to disease complexity to predict the success of the percutaneous coronary intervention (PCI). Comparison among different CTO scoring systems and long-term outcome for patients with CTO after PCI has not been well established. The objectives of the study were to assess the ability of different disease severity scoring systems to predict, first, procedural success and, second, overall survival in patients with a successful procedure. Materials and Methods: A total of 551 patients who underwent elective CTO PCI in Riga East University hospital from January 2007 to December 2016 were included in the study. Four scoring systems (J CTO, PROGRESS CTO, CL, and CASTLE) were calculated. ROC curves were used to assess the association between scores and procedural success, and the Kaplan–Meier method and Cox regression were used to estimate the association with death from any cause after a successful procedure, Results: 454 of 551 cases were successful. With increasing disease complexity, the procedural success rate was significantly reduced in all scoring systems (p < 0.001): Area under the curve was 0.714 for J CTO score, 0.605 for PROGRESS CTO, 0.624 for CL and 0.641 for CASTLE scores. During the median 6.8 years of follow-up time, survival was better in the successful procedure group (p = 0.041). Among patients with procedural success, only PROGRESS and CASTLE scores showed an association with all-cause risk of death. After adjustment for baseline characteristics, patients having high PROGRESS score had almost twice higher risk of death (HR 1.81(95% CI 1.19–2.75)), and those with high and intermediate CASTLE score experienced almost four (HR 3.68(95% CI 1.50–9.05)) and two (HR 2.15, (95% CI 1.42–3.23)) times higher risk of death than the low score patients, respectively. Conclusions: All four CTO scoring systems had moderate ability to predict procedural success. More complex CTO PCI patients, assessed by PROGRESS and CASTLE scores, has worse all-cause survival in six to seven years after a successful procedure; whereas J CTO and CL scores had no association with survival.publishersversionPeer reviewe

Eating patterns and food choices of latvian infants during their first year of life

Publisher Copyright: © 2018 by the authors. Licensee MDPI, Basel, Switzerland.Introduction: Pregnancy, infancy, and early childhood are periods of rapid growth and development. The role of nutrition is very important during these critical growth and development periods. The aim of the study was to investigate infant feeding practices through the first year of life in Latvia, and to compare feeding practices with nutritional guidelines in Latvia and other European countries. Methods: We analysed cross-sectional study data from food frequency questionnaires with additional questions on breastfeeding and complementary feeding introduction. A total of 266 infants from all Latvian regions from birth to 1-year-old were included in the study. Breastfeeding rates were assessed by month of age. Complementary feeding was assessed using three age groups (0-3.9 months, 4-6.9 months, and 7-12.9 months), whereas two groups were used to assess food frequency and portion sizes (0-5.9 months and 6-12.9 months). Results: The breastfeeding rate during the first month of life was 89%. At 6 months, 68% of infants received breast milk, but by 12 months, only 45% still received breast milk. Complementary foods were introduced at a mean age of 5 months (standard deviation = 1). Before 4 months of age, 9% of infants were receiving complementary food, the majority (85%) between 4 and 6 months of age. There were 6% of infants who were introduced to complementary foods after 7 months of age. First complementary food choices were mainly porridge (64%), vegetables (21%), and fruits (10%). After 6 months of age, foods from almost all food groups were present in each infant diet at least once per day, such as vegetables (85%), potatoes (85%), fruits (81%), dairy (78%), and meat (73%), less than once per day—grains (88%), fats (73%), cow’s milk (66%), eggs (45%), fish (36%), and legumes (28%). Conclusion: Breastfeeding rate during first months of life is high in Latvia. Breastfeeding was sustained at the age of 6 months, in the highest rate among Baltic countries. However, only 45% continued breastfeeding at the age of 12 months, in accordance with WHO recommendations. A guideline on complementary feeding is followed by the majority of parents. There are deviations from guidelines in inclusion of some foods in the diet and frequency of consumption.publishersversionPeer reviewe

Structure of the solar photosphere studied from the radiation hydrodynamics code ANTARES

The ANTARES radiation hydrodynamics code is capable of simulating the solar granulation in detail unequaled by direct observation. We introduce a state-of-the-art numerical tool to the solar physics community and demonstrate its applicability to model the solar granulation. The code is based on the weighted essentially non-oscillatory finite volume method and by its implementation of local mesh refinement is also capable of simulating turbulent fluids. While the ANTARES code already provides promising insights into small-scale dynamical processes occurring in the quiet-Sun photosphere, it will soon be capable of modeling the latter in the scope of radiation magnetohydrodynamics. In this first preliminary study we focus on the vertical photospheric stratification by examining a 3-D model photosphere with an evolution time much larger than the dynamical timescales of the solar granulation and of particular large horizontal extent corresponding to $25\!" \!\! \times \, 25\!"$ on the solar surface to smooth out horizontal spatial inhomogeneities separately for up- and downflows. The highly resolved Cartesian grid thereby covers $\sim 4~\mathrm{Mm}$ of the upper convection zone and the adjacent photosphere. Correlation analysis, both local and two-point, provides a suitable means to probe the photospheric structure and thereby to identify several layers of characteristic dynamics: The thermal convection zone is found to reach some ten kilometers above the solar surface, while convectively overshooting gas penetrates even higher into the low photosphere. An $\approx 145\,\mathrm{km}$ wide transition layer separates the convective from the oscillatory layers in the higher photosphere.Comment: Accepted for publication in Astrophysics and Space Science; 18 pages, 12 figures, 2 tables; typos correcte

Numerical solution of the generalised Poisson equation on parallel computers

Zur numerischen Lösung elliptischer Differentialgleichungen gibt es bereits viele bestens erprobte Algorithmen. Allerdings sind beim wissenschaftlichen Rechnen oftmals die Anforderungen an Arbeitsspeicher und Rechenleistung zu hoch, als dass sie von einem einzelnen Rechenkern erfüllt werden könnten. Daher muss die Rechenarbeit auf mehrere Kerne aufgeteilt werden, wofür spezielle Algorithmen notwendig sind. In dieser Diplomarbeit wird die Schur-Komplement-Methode vorgestellt, mit deren Hilfe das lineare Gleichungssystem, dass sich aus der Diskretisierung eines elliptischen Operators ergibt, parallel gelöst werden kann. Darüber hinaus wird anhand von zwei Beispielen die Bedeutung von elliptischen Operatoren in der Astrophysik gezeigt.There are a lot of well known algorithms to solve elliptic partial differential equations numerically. But for many applications, the computational domain and the memory requirements are too large for one single processing element (PE). The computational work must be done by several PE's and therefore the need of parallel algorithms arises. In this work the Schur Complement Method is presented with allows to solve the linear system corresponding to the discretisation of an elliptic operator in parallel. Furthermore, some examples of elliptic equations in Astrophyiscs are shown

Simulations of stellar convection, pulsation and semiconvection

We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations. Then, we turn to the first 2D model of pulsation-convection interaction in a cepheid. We discuss properties of the outer and the HEII ionization zone. Thirdly, we report on our work regarding models of semiconvection in the context of stellar physics.Comment: Astrophysical Dynamics: From Stars to Galaxies. IAU Symposium 27
