Kapitel 3. Sozioökonomische und klimatische Treiber der Änderung der Landnutzung in Österreich

Dieses Kapitel beschäftigt sich mit den klimatischen, ökologischen und sozioökonomischen treibenden Kräften, welche die Landnutzung in Österreich in der Vergangenheit und der Gegenwart maßgeblich bestimmt haben und die zukünftigen Entwicklungen beeinflussen werden. Es behandelt die in der Vergangenheit beobachteten und in der Zukunft erwarteten treibenden Kräfte von Landnutzungsänderungen in der Landwirtschaft (Abschn. 3.2), der Forstwirtschaft (Abschn. 3.3) und der Siedlungs- und Infrastrukturentwicklung (Abschn. 3.4). Abschließend werden die möglichen und erwarteten Auswirkungen dieser treibenden Kräfte auf die Bereitstellung der Ökosystemleistungen (ÖSL) beschrieben (Abschn. 3.5). Der Abbau von Mineralien wie Schotter oder Metalle wird aus Platzgründen nicht in diesem Kapitel behandelt, wenngleich es unumstritten ist, dass es sich auch dabei um landnutzungsrelevante Aktivitäten handelt. Kap. 3 unterscheidet zwischen natürlichen und anthropogenen Faktoren und wie sich diese auf die Landnutzung ausgewirkt haben und auswirken. Die sozioökonomischen Auswirkungen berücksichtigen dabei allerdings nicht die möglichen Anpassungs- oder Minderungsstrategien der einzelnen Sektoren, da diese in den Kap. 4 und 5 gesondert dargestellt werden

Past and future impacts of land-use changes on ecosystem services in Austria

Environmental and socio-economic developments induce land-use changes with potentially negative impacts on human well-being. To counteract undesired developments, a profound understanding of the complex relationships between drivers, land use, and ecosystem services is needed. Yet, national studies examining extended time periods are still rare. Based on the Special Report on land use, land management and climate change by the Austrian Panel on Climate Change (APCC), we use the Driver-Pressure-State-Impact-Response (DPSIR) framework to (1) identify the main drivers of land-use change, (2) describe past and future land-use changes in Austria between 1950 and 2100, (3) report related impacts on ecosystem services, and (4) discuss management responses. Our findings indicate that socio-economic drivers (e.g., economic growth, political systems, and technological developments) have influenced past land-use changes the most. The intensification of agricultural land use and urban sprawl have primarily led to declining ecosystem services in the lowlands. In mountain regions, the abandonment of mountain grassland has prompted a shift from provisioning to regulating services. However, simulations indicate that accelerating climate change will surpass socio-economic drivers in significance towards the end of this century, particularly in intensively used agricultural areas. Although climate change-induced impacts on ecosystem services remain uncertain, it can be expected that the range of land-use management options will be restricted in the future. Consequently, policymaking should prioritize the development of integrated land-use planning to safeguard ecosystem services, accounting for future environmental and socio-economic uncertainties

Repeated Courses of Radiosurgery for New Brain Metastases to Defer Whole Brain Radiotherapy: Feasibility and Outcome With Validation of the New Prognostic Metric Brain Metastasis Velocity

Stereotactic radiosurgery (SRS) is the preferred primary treatment option for patients with a limited number of asymptomatic brain metastases. In case of relapse after initial SRS the optimal salvage treatment is not well defined. Within this retrospective analysis, we investigated the feasibility of repeated courses of SRS to defer Whole-Brain Radiation Therapy (WBRT) and aimed to derive prognostic factors for patient selection. From 2014 until 2017, 42 patients with 197 brain metastases have been treated with multiple courses of SRS at our institution. Treatment was delivered as single fraction (18 or 20 Gy) or hypo-fractionated (6 fractions with 5 Gy) radiosurgery. Regular follow-up included clinical examination and contrast-enhanced cMRI at 3-4 months' intervals. Besides clinical and treatment related factors, brain metastasis velocity (BMV) as a newly described clinical prognostic metric was included and calculated between first and second treatment. A median number of 1 lesion (range: 1-13) per course and a median of 2 courses (range: 2-6) per patient were administered resulting in a median of 4 (range: 2-14) metastases treated over time per patient. The median interval between SRS courses was 5.8 months (range: 0.9-35 months). With a median follow-up of 17.4 months (range: 4.6-45.5 months) after the first course of treatment, a local control rate of 84% was observed after 1 year and 67% after 2 years. Median time to out-of-field-brain-failure (OOFBF) was 7 months (95%CI 4-8 months). WBRT as a salvage treatment was eventually required in 7 patients (16.6%). Median overall survival (OS) has not been reached. Grouped by ds-GPA (≤ 2 vs. >2) the survival curves showed a significant split ( = 0.039). OS differed also significantly between BMV-risk groups when grouped into low vs. intermediate/high risk groups ( = 0.025). No grade 4 or 5 acute or late toxicity was observed. In selected patients with relapse after SRS for brain metastases, repeat courses of SRS were safe and minimized the need for rescue WBRT. The innovative, yet easy to calculate metric BMV may facilitate treatment decisions as a prognostic factor for OS

Abstraction-based efficiency in the lexicon

Contains fulltext : 90732.pdf (publisher's version ) (Open Access)Listeners learn from their past experience of listening to spoken words, and use this learning to maximise the efficiency of future word recognition. This paper summarises evidence that the facilitatory effects of drawing on past experience are mediated by abstraction, enabling learning to be generalised across new words and new listening situations. Phoneme category retuning, which allows adaptation to speaker-specific articulatory characteristics, is generalised on the basis of relatively brief experience to words previously unheard from that speaker. Abstract knowledge of prosodic regularities is applied to recognition even of novel words for which these regularities were violated. Prosodic word-boundary regularities drive segmentation of speech into words independently of the membership of the lexical candidate set resulting from the segmentation operation. Each of these different cases illustrates how abstraction from past listening experience has contributed to the efficiency of lexical recognition.18 p
