Studies on ecosystem functions and services of woody vegetation require robust estimates of aboveground biomass (AGB). However, most methods have been developed for comparatively undisturbed forest ecosystems. As they are not tailored to accurately quantify AGB of small and irregular growth forms, their application on these growth forms may lead to unreliable or even biased AGB estimates in disturbance-prone dryland ecosystems. Moreover, these methods cannot quantify AGB losses caused by disturbance agents. Here we propose a methodology to estimate individual-and stand-level woody AGB in disturbance-prone ecosystems. It consists of flexible field sampling routines and estimation workflows for six growth classes, delineated by size and damage criteria. It also comprises a detailed damage assessment, harnessing the ecological archive of woody growth for past disturbances. Based on large inventories collected along steep gradients of elephant disturbances in African dryland ecosystems, we compared the AGB estimates generated with our proposed method against estimates from a less adapted forest inventory method. We evaluated the necessary stepwise procedures of method adaptation and analyzed each step's effect on stand-level AGB estimation. We further explored additional advantages of our proposed method with regard to disturbance impact quantification. Results indicate that a majority of growth forms and individuals in savanna vegetation could only be assessed if methods of AGB estimation were adapted to the conditions of a disturbance-prone ecosystem. Furthermore, our damage assessment demonstrated that one third to half of all woody AGB was lost to disturbances. Consequently, less adapted methods may be insufficient and are likely to render inaccurate AGB estimations. Our proposed method has the potential to accurately quantify woody AGB in disturbance-prone ecosystems, as well as AGB losses. Our method is more time consuming than conventional allometric approaches, yet it can cover sufficient areas within reasonable timespans, and can also be easily adapted to alternative sampling schemes.}, language = {en} } @article{KuhlmannBouckaertGallietal.2021, author = {Kuhlmann, Sabine and Bouckaert, Geert and Galli, Davide and Reiter, Renate and van Hecke, Steven}, title = {Opportunity management of the COVID-19 pandemic}, series = {International review of administrative sciences}, volume = {87}, journal = {International review of administrative sciences}, number = {3}, publisher = {Sage}, address = {Los Angeles, California}, issn = {0020-8523}, doi = {10.1177/0020852321992102}, pages = {497 -- 517}, year = {2021}, abstract = {This article provides a conceptual framework for the analysis of COVID-19 crisis governance in the first half of 2020 from a cross-country comparative perspective.

To date, the two most common statistical models used for the calculation of VA scores are two classical methods: linear regression and multilevel models. These models have the advantage of being relatively transparent and thus understandable for most researchers and practitioners. However, these statistical models are bound to certain assumptions (e.g., linearity) that might limit their prediction accuracy. Machine learning methods, which have yielded spectacular results in numerous fields, may be a valuable alternative to these classical models. Although big data is not new in general, it is relatively new in the realm of social sciences and education. New types of data require new data analytical approaches. Such techniques have already evolved in fields with a long tradition in crunching big data (e.g., gene technology). The objective of the present paper is to competently apply these "imported" techniques to education data, more precisely VA scores, and assess when and how they can extend or replace the classical psychometrics toolbox. The different models include linear and non-linear methods and extend classical models with the most commonly used machine learning methods (i.e., random forest, neural networks, support vector machines, and boosting). We used representative data of 3,026 students in 153 schools who took part in the standardized achievement tests of the Luxembourg School Monitoring Program in grades 1 and 3. Multilevel models outperformed classical linear and polynomial regressions, as well as different machine learning models. However, it could be observed that across all schools, school VA scores from different model types correlated highly. Yet, the percentage of disagreements as compared to multilevel models was not trivial and real-life implications for individual schools may still be dramatic depending on the model type used. Implications of these results and possible ethical concerns regarding the use of machine learning methods for decision-making in education are discussed.}, language = {en} } @article{BangeowRapp2020, author = {Bangeow, Petjo and Rapp, Michael Armin}, title = {Beurteilung und Nutzung der 2016 reformierten Psychotherapierichtlinie}, series = {Psychiatrische Praxis : Sozialpsychiatrie, klinische Psychiatrie, public mental health, Versorgungsforschung}, volume = {47}, journal = {Psychiatrische Praxis : Sozialpsychiatrie, klinische Psychiatrie, public mental health, Versorgungsforschung}, number = {07}, publisher = {Thieme}, address = {Stuttgart}, issn = {0303-4259}, doi = {10.1055/a-1045-9820}, pages = {383 -- 387}, year = {2020}, abstract = {Ziel der Studie Dieser Artikel untersucht, inwiefern sich die 2016 reformierte Richtlinie im Stadt-Land- sowie im Ost-West-Vergleich auf die ambulante psychotherapeutische Arbeit und Versorgung auswirkt.

Points for practitioners Decentralization reforms are approved as having a key role to play in the attainment of 'good governance'. Yet, there is also the enticement on the part of state governments to offload an ever-increasing amount of responsibilities to, and overtask, local levels of government, which can lead to increasing performance disparities within local sub-state jurisdictions.

However, western blot is technically difficult to perform in large sample sizes because it is a time consuming and labor intensive process. Dot blot is often used instead when dealing with large sample sizes, but the main disadvantage of the existing dot blot techniques, is the absence of signal normalization to a housekeeping protein. Methods: In this study we established a one dot two development signals (ODTDS) dot blot method employing two different signal development systems. The first signal from the protein of interest was detected by horseradish peroxidase (HRP). The second signal, detecting the housekeeping protein, was obtained by using alkaline phosphatase (AP). Results: Inter-assay results variations within ODTDS dot blot and western blot and intra-assay variations between both methods were low (1.04 - 5.71\%) as assessed by coefficient of variation. Conclusions: ODTDS dot blot technique can be used instead of western blot when dealing with large sample sizes without a reduction in results accuracy.}, language = {en} }
