Seit dem 01. 04. 2017 erfolgte eine umfangreiche Reform der Psychotherapie-Richtlinie. Neben der Einführung neuer Leistungen (z. B. Akutbehandlung, psychotherapeutische Sprechstunde) wurden auch Änderungen im Ablauf und der Beantragung von Psychotherapie beschlossen. Beispielsweise ist der Bericht an den Gutachter bzw. die Gutachterin seltener eine notwendige Voraussetzung zur Durchführung einer psychotherapeutischen Behandlung, als dass zuvor der Fall war. Im Zuge der Reform wurde auch der Leitfaden für die Gestaltung des Berichts an den Gutachter bzw. die Gutachterin überarbeitet.
Vor dem Hintergrund der Psychotherapie-Richtlinien-Reform ist das Werk „Leitfaden für den VT-Bericht an den Gutachter“ von Daniel Surall und Oliver Kunz sehr willkommen. Das Buch gliedert sich insgesamt in zehn Kapitel, in denen die Autoren ausführlich auf den reformierten Bericht an den Gutachter bzw. an die Gutachterin eingehen. In den ersten beiden Kapiteln fassen die Autoren die Änderungen zur Psychotherapie-Richtlinie und im Bericht an den Gutachter / die Gutachterin zusammen. In den folgenden sechs Kapiteln wird auf die einzelnen Abschnitte des neuen Berichts an den Gutachter/die Gutachterin eingegangen. Sehr hilfreich ist hierbei, dass die Autoren zahlreiche Fallbeispiele nutzen, um die einzelnen Abschnitte des Berichts an den Gutachter/die Gutachterin zu erläutern. Auch die übersichtliche Darstellungsform in Form von Tabellen (z. B. zur Darstellung der Verhaltensanalyse) erleichtert den Leser_innen die Nachvollziehbarkeit der Inhalte. Erfreulich ist auch, dass die Autoren hinsichtlich der Antragstellung auch immer auf Unterschiede zwischen erwachsenen Patient_innen und Kindern und Jugendlichen eingehen. Im neunten Kapitel des Leitfadens wird ausführlicher das Thema Umwandlungs- und Fortführungsanträge aufgegriffen. Dies ist insbesondere sinnvoll, da nach der neuen Psychotherapie-Richtlinie für Kurzzeitanträge in der Regel keine Berichtspflicht besteht und Umwandlungs- und Fortführungsanträge in der Praxis häufiger als zuvor von Relevanz sein dürften. Im zehnten Kapitel wird in knapper Weise darauf eingegangen, wie bei Ablehnung oder Kürzung von beantragten Leistungen vorgegangen werden kann.
Das Buch umfasst einen umfangreichen Anhang (67 Seiten), in dem Beispiele für Berichte an den Gutachter / die Gutachterin und Behandlungspläne für verschiedene psychische Störungen zu finden sind. Auch hierbei werden sowohl Berichte für Erwachsene als auch für Kinder und Jugendliche präsentiert. Zudem beinhaltet der Anhang des Buches das Berner Inventar für Therapieziele, Auszüge aus dem AMDP-Befundbogen (Arbeitsgemeinschaft Methodik und Dokumentation in der Psychiatrie, 2018)<\litr>, den Leitfaden zum Erstellen des Berichts an die Gutachter_innen (PTV 3) sowie einer Gegenüberstellung des alten und des neuen Leitfadens für den Bericht an die Gutachter_innen.
Bei dem von Surall und Kunz vorgelegten Buch handelt es sich um einen äußerst hilfreichen Leitfaden, der Therapeut:innen bei der Abfassung des Berichts an den Gutachter / die Gutachterin im Rahmen der Verhaltenstherapie unterstützen kann. Hierbei kann der Leitfaden Psychotherapeut_innen in Ausbildung bei der Abfassung ihrer ersten Anträge unterstützen. Aber auch erfahrenen Kolleg_innen können bei dem Übergang in die neuen Antragsformalitäten, die mit der Reform der Psychotherapie-Richtlinie einhergingen, unterstützen werden. Hierbei ist insbesondere die Im Anhang befindliche Gegenüberstellung des alten und des neuen Leitfadens für den Bericht an den Gutachter / die Gutachterin hilfreich, um sich einen schnellen Überblick über die Änderungen zu verschaffen. Insgesamt werden die einzelnen Abschnitte des Berichts an den Gutachter / die Gutachterin sehr gut strukturiert und verständlich erläutert. Die vielen Beispiele und die ausführlichen Materialien im Anhang ergänzen zudem die Erläuterungen und erleichtern das Verständnis. Zu Beginn des Buches wäre zudem noch eine Abbildung hilfreich gewesen, die den Ablauf der Beantragung von Psychotherapie schematisch darstellt, um einen genaueren Überblick über die Beantragung von Psychotherapie nach der neuen Psychotherapie-Richtlinie zu erhalten. Auch ein Stichwortverzeichnis würde die Suche nach bestimmten Inhalten erleichtern.
Zusammenfassend kann festgehalten werden, dass es sich bei dem Werk von Surall und Kunz um einen sehr empfehlenswerten Leitfaden handelt, der im Rahmen der Antragstellung von Verhaltenstherapie genutzt werden kann. Aufgrund der klaren Struktur und Anschaulichkeit durch viele Beispielanträge bringt das Buch alle Voraussetzungen mit, um sich als Standartwerk zu etablieren, dass Therapeut_innen bei der Beantragung von Verhaltenstherapie in äußerst hilfreicher Weise unterstützt.
Brownian motion and viscoelastic anomalous diffusion in homogeneous environments are intrinsically Gaussian processes. In a growing number of systems, however, non-Gaussian displacement distributions of these processes are being reported. The physical cause of the non-Gaussianity is typically seen in different forms of disorder. These include, for instance, imperfect "ensembles" of tracer particles, the presence of local variations of the tracer mobility in heteroegenous environments, or cases in which the speed or persistence of moving nematodes or cells are distributed. From a theoretical point of view stochastic descriptions based on distributed ("superstatistical") transport coefficients as well as time-dependent generalisations based on stochastic transport parameters with built-in finite correlation time are invoked. After a brief review of the history of Brownian motion and the famed Gaussian displacement distribution, we here provide a brief introduction to the phenomenon of non-Gaussianity and the stochastic modelling in terms of superstatistical and diffusing-diffusivity approaches.
Electrochemical methods offer the simple characterization of the synthesis of molecularly imprinted polymers (MIPs) and the readouts of target binding. The binding of electroinactive analytes can be detected indirectly by their modulating effect on the diffusional permeability of a redox marker through thin MIP films. However, this process generates an overall signal, which may include nonspecific interactions with the nonimprinted surface and adsorption at the electrode surface in addition to (specific) binding to the cavities. Redox-active low-molecular-weight targets and metalloproteins enable a more specific direct quantification of their binding to MIPs by measuring the faradaic current. The in situ characterization of enzymes, MIP-based mimics of redox enzymes or enzyme-labeled targets, is based on the indication of an electroactive product. This approach allows the determination of both the activity of the bio(mimetic) catalyst and of the substrate concentration.

The biosynthesis of the molybdenum cofactor (Moco) is highly conserved among all kingdoms of life. In all molybdoenzymes containing Moco, the molybdenum atom is coordinated to a dithiolene group present in the pterin-based 6-alkyl side chain of molybdopterin (MPT). In general, the biosynthesis of Moco can be divided into four steps in in bacteria: (i) the starting point is the formation of the cyclic pyranopterin monophosphate (cPMP) from 5 '-GTP, (ii) in the second step the two sulfur atoms are inserted into cPMP leading to the formation of MPT, (iii) in the third step the molybdenum atom is inserted into MPT to form Moco and (iv) in the fourth step bis-Mo-MPT is formed and an additional modification of Moco is possible with the attachment of a nucleotide (CMP or GMP) to the phosphate group of MPT, forming the dinucleotide variants of Moco. This review presents an update on the well-characterized Moco biosynthesis in the model organism Escherichia coli including novel discoveries from the recent years.
Plans are currently being drafted for the next decade of action on biodiversity-both the post-2020 Global Biodiversity Framework of the Convention on Biological Diversity (CBD) and Biodiversity Strategy of the European Union (EU). Freshwater biodiversity is disproportionately threatened and underprioritized relative to the marine and terrestrial biota, despite supporting a richness of species and ecosystems with their own intrinsic value and providing multiple essential ecosystem services. Future policies and strategies must have a greater focus on the unique ecology of freshwater life and its multiple threats, and now is a critical time to reflect on how this may be achieved. We identify priority topics including environmental flows, water quality, invasive species, integrated water resources management, strategic conservation planning, and emerging technologies for freshwater ecosystem monitoring. We synthesize these topics with decades of first-hand experience and recent literature into 14 special recommendations for global freshwater biodiversity conservation based on the successes and setbacks of European policy, management, and research. Applying and following these recommendations will inform and enhance the ability of global and European post-2020 biodiversity agreements to halt and reverse the rapid global decline of freshwater biodiversity.
The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records. It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. Our synthesis shows that the Central Asian steppe-desert has existed since at least Eocene times but experienced no less than two regime shifts, one at the Eocene-Oligocene Transition and one in the mid-Miocene. These shifts separated three successive "stable states," each characterized by unique floral and faunal structures. Past responses to disturbance in the Asian steppe-desert imply that modern ecosystems are unlikely to recover their present structures and diversity if forced into a new regime. This is of concern for Asian steppes today, which are being modified for human use and lost to desertification at unprecedented rates.
Theoretischer Hintergrund:Supervision spielt eine zentrale Rolle zum Wissens- und Kompetenzerwerb sowie in der Qualitätssicherung.
Fragestellung:Ziel war es, den aktuellen Forschungsstand zur Supervision im Rahmen der kognitiven Verhaltenstherapie abzubilden, um daraus Schlussfolgerungen für die zukünftige Forschung abzuleiten.
Methode:Zur Evidenzsynthese wurde ein Scoping Review durchgeführt, das die Darstellung zentraler Konzepte, aktueller Evidenz und möglicher Forschungsbedarfe ermöglichte. Neben einer systematischen Literaturrecherche wurden Vorwärts- und Rückwärtssuchstrategien eingesetzt.
Ergebnisse:Eingeschlossen wurden zwölf Publikationen basierend auf zehn empirischen Studien. Alle Studien beschrieben Ausbildungssettings, aber nur wenige untersuchten übende Interventionen (z. B. Rollenspiele). Häufig wurden Effekte subjektiv erfasst, die methodische Qualität der Begleitstudien variierte.
Schlussfolgerungen:Notwendig sind weitere methodisch hochwertige Studien, experimentell orientiert oder in der klinischen Praxis, die die Supervisionsforschung bereichern können.
Bullying ist eine Form wiederholten, aggressiven Verhaltens mit ernstzunehmenden Auswirkungen, unter denen Täter und Opfer häufig lange nach Ende des Bullying-Geschehens leiden. Dennoch ist die Therapie von Bullying und den damit einhergehenden Folgen ein bisher in der Forschung vernachlässigtes Thema. Im Rahmen eines systematischen Literaturüberblicks wurde daher untersucht, welche Therapieformen zur Behandlung von Bullying und dessen Folgen bei Opfern und bei Tätern bereits angewendet wurden. Eine systematische Suche in nationalen und internationalen Datenbanken führte zu 31 relevanten Publikationen, in denen 34 therapeutische Interventionen aus über 14 Ländern beschrieben wurden. In zehn Therapiestudien mit kontrolliertem Design zeigte sich, dass Behandlungsangebote, die sich sowohl an die betroffenen Personen als auch an ihr soziales Umfeld richten, besonders effektiv in der Behandlung von Bullying-Folgen sind. Die restlichen 24 Behandlungsansätze wurden keiner kontrollierten Evaluation unterzogen. Insgesamt zwei Drittel aller therapeutischen Interventionen wenden sich an die Gruppe der Opfer. Hier wird im Unterschied zur Behandlung von Tätern verstärkt auf Gruppentherapien zurückgegriffen. Unter der Bandbreite an Ansätzen ist die kognitive Verhaltenstherapie am häufigsten vertreten. Festzustellen bleibt ein Forschungsmangel an evidenzbasierten, gezielten Interventionen zur Behandlung von Bullying und dessen Folgen bei Opfern und Tätern. Unseres Wissens stellt diese Arbeit den ersten systematischen Überblick zu therapeutischen Interventionen bei Bullying für Kinder und Jugendliche dar.
Starch is one of the most popular nutritional sources for both human and animals. Due to the variation of its nutritional traits and biochemical specificities, starch has been classified into rapidly digestible, slowly digestible and resistant starch. Resistant starch has its own unique chemical structure, and various forms of resistant starch are commercially available. It has been found being a multiple-functional regulator for treating metabolic dysfunction. Different functions of resistant starch such as modulation of the gut microbiota, gut peptides, circulating growth factors, circulating inflammatory mediators have been characterized by animal studies and clinical trials. In this mini-review, recent remarkable progress in resistant starch on gut microbiota, particularly the effect of structure, biochemistry and cell signaling on nutrition has been summarized, with highlights on its regulatory effect on gut microbiota.
Fragmentation of landscapes creates a transition zone in between natural habitats or different kinds of land use. In forested and agricultural landscapes with transition zones, microclimate and matter cycling are markedly altered. This probably accelerates and is intensified by global warming. However, there is no consensus on defining transition zones and quantifying relevant variables for microclimate and matter cycling across disciplines. This article is an attempt to a) revise definitions and offer a framework for quantitative ecologists, b) review the literature on microclimate and matter cycling in transition zones and c) summarise this information using meta-analysis to better understand bio-geochemical and bio-geophysical processes and their spatial extent in transition zones. We expect altered conditions in soils of transition zones to be 10-20 m with a maximum of 50 m, and 25-50 m for above-ground space with a maximum of 125 m.
We study differential cohomology on categories of globally hyperbolic Lorentzian manifolds. The Lorentzian metric allows us to define a natural transformation whose kernel generalizes Maxwell's equations and fits into a restriction of the fundamental exact sequences of differential cohomology. We consider smooth Pontryagin duals of differential cohomology groups, which are subgroups of the character groups. We prove that these groups fit into smooth duals of the fundamental exact sequences of differential cohomology and equip them with a natural presymplectic structure derived from a generalized Maxwell Lagrangian. The resulting presymplectic Abelian groups are quantized using the CCR-functor, which yields a covariant functor from our categories of globally hyperbolic Lorentzian manifolds to the category of C∗-algebras. We prove that this functor satisfies the causality and time-slice axioms of locally covariant quantum field theory, but that it violates the locality axiom. We show that this violation is precisely due to the fact that our functor has topological subfunctors describing the Pontryagin duals of certain singular cohomology groups. As a byproduct, we develop a Fréchet–Lie group structure on differential cohomology groups.
Macroecology and biogeography are concerned with understanding biodiversity patterns across space and time. In the past, the two disciplines have addressed this question mainly with correlative approaches, despite frequent calls for more mechanistic explanations. Recent advances in computational power, theoretical understanding, and statistical tools are, however, currently facilitating the development of more system-oriented, mechanistic models. We review these models, identify different model types and theoretical frameworks, compare their processes and properties, and summarize emergent findings. We show that ecological (physiology, demographics, dispersal, biotic interactions) and evolutionary processes, as well as environmental and human-induced drivers, are increasingly modelled mechanistically; and that new insights into biodiversity dynamics emerge from these models. Yet, substantial challenges still lie ahead for this young research field. Among these, we identify scaling, calibration, validation, and balancing complexity as pressing issues. Moreover, particular process combinations are still understudied, and so far models tend to be developed for specific applications. Future work should aim at developing more flexible and modular models that not only allow different ecological theories to be expressed and contrasted, but which are also built for tight integration with all macroecological data sources. Moving the field towards such a ‘systems macroecology’ will test and improve our understanding of the causal pathways through which eco-evolutionary processes create diversity patterns across spatial and temporal scales.
Cities and Mental Health
(2017)
Background: More than half of the global population currently lives in cities, with an increasing trend for further urbanization. Living in cities is associated with increased population density, traffic noise and pollution, but also with better access to health care and other commodities. Methods: This review is based on a selective literature search, providing an overview of the risk factors for mental illness in urban centers. Results: Studies have shown that the risk for serious mental illness is generally higher in cities compared to rural areas. Epidemiological studies have associated growing up and living in cities with a considerably higher risk for schizophrenia. However, correlation is not causation and living in poverty can both contribute to and result from impairments associated with poor mental health. Social isolation and discrimination as well as poverty in the neighborhood contribute to the mental health burden while little is known about specific inter actions between such factors and the built environment. Conclusion: Further insights on the interaction between spatial heterogeneity of neighborhood resources and socio-ecological factors is warranted and requires interdisciplinary research.
Modifications of transfer RNA (tRNA) have been shown to play critical roles in the biogenesis, metabolism, structural stability and function of RNA molecules, and the specific modifications of nucleobases with sulfur atoms in tRNA are present in pro- and eukaryotes. Here, especially the thiomodifications xm(5)s(2)U at the wobble position 34 in tRNAs for Lys, Gln and Glu, were suggested to have an important role during the translation process by ensuring accurate deciphering of the genetic code and by stabilization of the tRNA structure. The trafficking and delivery of sulfur nucleosides is a complex process carried out by sulfur relay systems involving numerous proteins, which not only deliver sulfur to the specific tRNAs but also to other sulfur-containing molecules including iron-sulfur clusters, thiamin, biotin, lipoic acid and molybdopterin (MPT). Among the biosynthesis of these sulfur-containing molecules, the biosynthesis of the molybdenum cofactor (Moco) and the synthesis of thio-modified tRNAs in particular show a surprising link by sharing protein components for sulfur mobilization in pro- and eukaryotes.
The biomolecule is among the most important building blocks of biological systems, and a full understanding of its function forms the scaffold for describing the mechanisms of higher order structures as organelles and cells. Force is a fundamental regulatory mechanism of biomolecular interactions driving many cellular processes. The forces on a molecular scale are exactly in the range that can be manipulated and probed with single molecule force spectroscopy. The natural environment of a biomolecule is inside a living cell, hence, this is the most relevant environment for probing their function. In vivo studies are, however, challenged by the complexity of the cell. In this review, we start with presenting relevant theoretical tools for analyzing single molecule data obtained in intracellular environments followed by a description of state-of-the art visualization techniques. The most commonly used force spectroscopy techniques, namely optical tweezers, magnetic tweezers, and atomic force microscopy, are described in detail, and their strength and limitations related to in vivo experiments are discussed. Finally, recent exciting discoveries within the field of in vivo manipulation and dynamics of single molecule and organelles are reviewed.
Aldehyde oxidases (AOXs) are molybdo-flavoenzymes characterized by broad substrate specificity, oxidizing aromatic/aliphatic aldehydes into the corresponding carboxylic acids and hydroxylating various heteroaromatic rings. Mammals are characterized by a complement of species specific AOX isoenzymes, that varies from one in humans (AOX1) to four in rodents (AOX1, AOX2, AOX3 and AOX4). The physiological function of mammalian AOX isoenzymes is unknown, although human AOX1 is an emerging enzyme in phase-I drug metabolism. Indeed, the number of therapeutic molecules under development which act as AOX substrates is increasing. The recent crystallization and structure determination of human AOX1 as well as mouse AOX3 has brought new insights into the mechanisms underlying substrate/inhibitor binding as well as the catalytic activity of this class of enzymes.
The cryosphere in mountain regions is rapidly declining, a trend that is expected to accelerate over the next several decades due to anthropogenic climate change. A cascade of effects will result, extending from mountains to lowlands with associated impacts on human livelihood, economy, and ecosystems. With rising air temperatures and increased radiative forcing, glaciers will become smaller and, in some cases, disappear, the area of frozen ground will diminish, the ratio of snow to rainfall will decrease, and the timing and magnitude of both maximum and minimum streamflow will change. These changes will affect erosion rates, sediment, and nutrient flux, and the biogeochemistry of rivers and proglacial lakes, all of which influence water quality, aquatic habitat, and biotic communities. Changes in the length of the growing season will allow low-elevation plants and animals to expand their ranges upward. Slope failures due to thawing alpine permafrost, and outburst floods from glacier-and moraine-dammed lakes will threaten downstream populations.Societies even well beyond the mountains depend on meltwater from glaciers and snow for drinking water supplies, irrigation, mining, hydropower, agriculture, and recreation. Here, we review and, where possible, quantify the impacts of anticipated climate change on the alpine cryosphere, hydrosphere, and biosphere, and consider the implications for adaptation to a future of mountains without permanent snow and ice.
Molecularly imprinted polymers (MIPs) have the potential to complement antibodies in bioanalysis, are more stable under harsh conditions, and are potentially cheaper to produce. However, the affinity and especially the selectivity of MIPs are in general lower than those of their biological pendants. Enzymes are useful tools for the preparation of MIPs for both low and high-molecular weight targets: As a green alternative to the well-established methods of chemical polymerization, enzyme-initiated polymerization has been introduced and the removal of protein templates by proteases has been successfully applied. Furthermore, MIPs have been coupled with enzymes in order to enhance the analytical performance of biomimetic sensors: Enzymes have been used in MIP-sensors as tracers for the generation and amplification of the measuring signal. In addition, enzymatic pretreatment of an analyte can extend the analyte spectrum and eliminate interferences.
Diabetic nephropathy is one of the most frequent, devastating and costly complications of diabetes. The available therapeutic approaches are limited. Dipeptidyl peptidase type 4 (DPP-4) inhibitors represent a new class of glucose-lowering drugs that might also have reno-protective properties. DPP-4 exists in two forms: a plasma membranebound form and a soluble form, and can exert many biological actions mainly through its peptidase activity and interaction with extracellular matrix components. The kidneys have the highest DPP-4 expression level in mammalians. DPP-4 expression and urinary activity are up-regulated in diabetic nephropathy, highlighting its role as a potential target to manage diabetic nephropathy. Preclinical animal studies and some clinical data suggest that DPP-4 inhibitors decrease the progression of diabetic nephropathy in a blood pressure-and glucose-independent manner. Many studies reported that these reno-protective effects could be due to increased half-life of DPP-4 substrates such as glucagon-like peptide-1 (GLP-1) and stromal derived factor-1 alpha (SDF-1a). However, the underlying mechanisms are far from being completely understood and clearly need further investigations.
This article presents a review of the current data on the level of paleolimnological knowledge about lakes in the Russian part of the northern Eurasia. The results of investigation of the northwestern European part of Russia as the best paleolimnologically studied sector of the Russian north is presented in detail. The conditions of lacustrine sedimentation at the boundary between the Late Pleistocene and Holocene and the role of different external factors in formation of their chemical composition, including active volcanic activity and possible large meteorite impacts, are also discussed. The results of major paleoclimatic and paleoecological reconstructions in northern Siberia are presented. Particular attention is given to the databases of abiotic and biotic parameters of lake ecosystems as an important basis for quantitative reconstructions of climatic and ecological changes in the Late Pleistocene and Holocene. Keywords: paleolimnology, lakes, bottom sediments, northern.
Second harmonic generation (SHG) is a nonlinear optical process that inherently generates signal in non-centrosymmetric materials, such as starch granules, and therefore can be used for label-free imaging. Both intensity and polarization of SHG are determined by material properties that are characterized by the nonlinear susceptibility tensor, ((2)). Examination of the tensor is performed for each focal volume of the image by measuring the outgoing polarization state of the SHG signal for a set of incoming laser beam polarizations. Mapping of nonlinear properties expressed as the susceptibility ratio reveals structural features including the organization of crystalline material within a single starch granule, and the distribution of structural properties in a population of granules. Isolated granules, as well as in situ starch, can be analyzed using polarimetric SHG microscopy. Due to the fast sample preparation and short imaging times, polarimetric SHG microscopy allows for a quick assessment of starch structure and permits rapid feedback for bioengineering applications. This article presents the basics of SHG theory and microscopy applications for starch-containing materials. Quantification of ultrastructural features within individual starch granules is described. New results obtained by polarization resolved SHG microscopy of starch granules are presented for various maize genotypes revealing heterogeneity within a single starch particle and between various granules.
Like almost all fields of science, hydrology has benefited to a large extent from the tremendous improvements in scientific instruments that are able to collect long-time data series and an increase in available computational power and storage capabilities over the last decades. Many model applications and statistical analyses (e.g., extreme value analysis) are based on these time series. Consequently, the quality and the completeness of these time series are essential. Preprocessing of raw data sets by filling data gaps is thus a necessary procedure. Several interpolation techniques with different complexity are available ranging from rather simple to extremely challenging approaches. In this paper, various imputation methods available to the hydrological researchers are reviewed with regard to their suitability for filling gaps in the context of solving hydrological questions. The methodological approaches include arithmetic mean imputation, principal component analysis, regression-based methods and multiple imputation methods. In particular, autoregressive conditional heteroscedasticity (ARCH) models which originate from finance and econometrics will be discussed regarding their applicability to data series characterized by non-constant volatility and heteroscedasticity in hydrological contexts. The review shows that methodological advances driven by other fields of research bear relevance for a more intensive use of these methods in hydrology. Up to now, the hydrological community has paid little attention to the imputation ability of time series models in general and ARCH models in particular.
Single molecule RNA fluorescent in situ hybridization (smFISH) enables gene transcription to be assessed at the cellular level. In this point of view article, we describe our recent smFISH research in the model plant Arabidopsis thaliana and discuss how this technique could further knowledge of plant gene transcription in the future.
This is a brief survey of a constructive technique of analytic continuation related to an explicit integral formula of Golusin and Krylov (1933). It goes far beyond complex analysis and applies to the Cauchy problem for elliptic partial differential equations as well. As started in the classical papers, the technique is elaborated in generalised Hardy spaces also called Hardy-Smirnov spaces.
This article presents some insights into the German developments of studying Judaism and the Jewish tradition and relates them to the ongoing development of the subject at universities in the Nordic countries in general and Norway in particular. It also aims to present some conclusions concerning why it might be interesting for Norwegian society to intensify the study of Judaism at its universities.
In order to replace bio-macromolecules by stable synthetic materials in separation techniques and bioanalysis biomimetic receptors and catalysts have been developed: Functional monomers are polymerized together with the target analyte and after template removal cavities are formed in the "molecularly imprinted polymer" (MIP) which resemble the active sites of antibodies and enzymes. Starting almost 80 years ago, around 1,100 papers on MIPs were published in 2016. Electropolymerization allows to deposit MIPs directly on voltammetric electrodes or chips for quartz crystal microbalance (QCM) and surface plasmon resonance (SPR). For the readout of MIPs for drugs amperometry, differential pulse voltammetry (DPV) and impedance spectroscopy (EIS) offer higher sensitivity as compared with QCM or SPR. Application of simple electrochemical devices allows both the reproducible preparation of MIP sensors, but also the sensitive signal generation. Electrochemical MIP-sensors for the whole arsenal of drugs, e.g. the most frequently used analgesics, antibiotics and anticancer drugs have been presented in literature and tested under laboratory conditions. These biomimetic sensors typically have measuring ranges covering the lower nano-up to millimolar concentration range and they are stable under extreme pH and in organic solvents like nonaqueous extracts.
In this article, I analyze patterns of reflexes of A-movement found within and across languages: reflexes may occur in all or none of the clauses of the dependency, in the clause where the dependency terminates, or solely in clauses where it does not terminate. I argue that the variation can best be captured by the variable timing of Agree and two subtypes of internal Merge (final vs. intermediate movement steps) triggered by a single head: early movement feeds Agree and gives rise to a reflex; late movement has the opposite effect. Since the subtypes of movement can apply at different points relative to Agree, reflexes may occur only in some clauses of the dependency.
Silicon (Si) is considered as a quasiessential element for higher plants as its uptake increases plant growth and resistance against abiotic as well as biotic stresses. Foliar application of fertilizers generally is assumed to be a comparably environment-friendly form of fertilization because only small quantities are needed. The interest in foliar fertilization and the use of Si as a fertilizer in general increased significantly within the last decades, but there are only few publications dealing with the foliar application of Si at all. In the present review, the effects of Si foliar fertilization, including nano-Si fertilizers, on the three most important crops on a global scale, that is, maize, rice, and wheat, are summarized. Additionally, different pathways (i.e., cuticular pathways, stomata, and trichomes) of foliar uptake and functioning of Si foliar fertilizers against biotic (i.e., fungal diseases and harmful insects), as well as abiotic (i.e., water stress, macronutrient imbalance, and heavy metal toxicity) stressors are discussed. Future research should especially focus on (1) the gathering of empirical data from field and greenhouse experiments, (2) the intensification of co-operations between practitioners and scientists, (3) interdisciplinary research, and (4) the analysis of results from multiple studies (meta-analysis, big data) to fully understand effects, uptake, and functioning of Si foliar fertilizers and to evaluate their potential in modern sustainable agriculture concepts.
"מגילת שיר השירים היא יצירה עתיקה וחידתית. מילותיה הייחודיות שזורות ביד אמן. תשומת לב למלאכת רקמה עדינה זו ולהתכתבותה עם מקורות מקראיים אחרים פותחת נתיבי פרשנות מפתיעים. הספר 'מי זאת עולה מן המדבר' מציע שלוש קריאות במגילה ועונה לשאלה 'מי זאת' שלוש תשובות מהפכניות:• הקריאה הראשונה עוסקת ביחסים שבין גברים ונשים ובקשר שבין אהבה וחופש. הקול הנשי העולה בה הוא קולה של אישה המתבוננת בדפוסי הזוגיות המוכרים לה וקוראת לשינוי מהותי בהם.• הקריאה השנייה עוסקת ביחסים שבין האדם והאלוהות. הדמות הנשית המתגלה בו היא דמותה של האלוהות החושפת את מנגנוני הכוח שבממסד הדתי ומציעה לאדם קשר המושתת על חירות ואהבה.• בקריאה השלישית הדמות הנשית היא ההוויה כולה. היא עוסקת בקשר שבין ההוויה לתודעה האנושית החופשית במהותה ובאפשרות של השפה לחבר ביניהן באהבה.יחד, הקולות הנשיים הללו מציעים לנו, כחברה וכיחידים, תהליך צמיחה שבליבו אהבה וחירות החיוניות זו לקיומה של זו."שיר השירים הוא שירת הפצעה גדולה של אהבה. כוח אהבה, שאין דבר שישווה לו מבין כל כוחות עולם. אבל ההפצעה הזו, מקורה בפצע, פצע שכולנו נושאות ונושאים בתוכנו כבר דורי דורות, פצע הקשר בין גברים ונשים. כמה לא מתואמות יכולות להיות השפות שלנו על הציר המתעתע שבין תאווה לאהבה, כמה אי הלימה יכולה להיות בין שפת האם של השכינה והאשה, שפת אתיקה של אהבה, של נאמנות, לשפות אהבה שהן במסווה ובנתק. ואיך נצמיח בעולם אהבת אמת, עדינה, חופשייה ושלמה.פירושה של מרב מזא"ה הוא רגע היסטורי. בדור פצוע אהבה, בשפה ברורה ובהירה, שכבה אחר שכבה, בסבלנות ובחכמה של התגלות, לוקחת מרב את קוראיה למסע אל עומק הפצע. בהלימה בין תוכן המגילה לצורה בה בחרה לכתוב את פירושה, בבחירה ללכת עם הקוראים לאט את המסע כולו, פסוק אחר פסוק, במסע שכוחו לא רק בפענוח אלא גם בקצב המוענק לכל קורא על פי דרכו, נותנת מרב הזדמנות לכל אחת ואחד לצלול אל המגילה, לכאוב איתה ולהירפא מכוחה. מסע שיר השירים הוא הזמנה עתיקה ונמשכת שהגיעה שעתה, הזמנה לנשים וגברים לכאוב יחד את נתק הקשר, לשמוע זה את קולו של זו, לספר את פציעות הלב והגוף, ולהתגלות זו לזה במסע אמון ואמונה, איחוי וריפוי, מסע אהבת אמת העולה לרגל לירושלים, אל השלם." -- מן המעטפת האחורית.
