    Description: The income tax rate structure introduced in 2007 was changed in 2009. The income tax rates will be lowered in 2010, too. The effects on the wage income tax revenues and on the incentives to work are analyzed. It turns out that "bracket creep" will remain a problem in Germany.

    Description: The gross wage income distributions for different groups of taxpayers in 2004 are used to derive wage income distributions for 20072013. By applying the rules of income taxation, wage income tax revenues are deduced. Given the tax rate structure introduced in 2007, the average tax rates and the marginal tax rates will increase. However, the income tax rates were reduced in 2009 and will be reduced in 2010. Nevertheless, "bracket creep" will remain a problem in Germany.

    Description: Der Einkommensteuertarif Deutschlands impliziert für die nächsten Jahre eine deutliche Zunahme der Grenz- und Durchschnittssätze selbst bei einem bescheidenen Anstieg der nominalen Einkommen. Die Aufkommenselastizität der Lohnsteuer bezüglich des Bruttolohns eines Beschäftigten im Durchschnitt beträgt rund 1,9, wenn man Lohnsteigerungen von jahresdurchschnittlich 1 – Prozent zugrunde legt; ein Lohnanstieg in dieser Größenordnung bedeutet vermutlich lediglich, dass der an der Veränderung des Verbraucherpreisindex gemessene Reallohn konstant bleibt. Der Einkommensteuertarif erweist sich als Wachstumsbremse. Es sind regelmäßig Steuersatzreduktionen nötig, wenn die Leistungsanreize nicht noch mehr als gegenwärtig beeinträchtigt werden sollen. Abhilfe könnte eine Indexierung der Abzugsbeträge und des Steuertarifs bringen.
    Description: The structure of income taxation in Germany implies that the marginal and the average tax rates will rise in the course of the coming yearseven if the increase of nominal incomes is modest. The elasticity of the wage income tax revenues with respect to gross wages amounts to about 1.9, assuming that average wages rise by 1.5 percent per year; such wage increases would probably mean that real wages remain constant. The rising tax rates impair the incentive to work and dampen the growth of potential output. Regular tax rate cuts would seem to be necessary to avoid bracket creep. Indexation of the income tax system might be a real option for economic policy.

    Description: Climate change will alter turbulence intensity, motivating greater attention to mechanisms of turbulence effects on organisms. Many analytic and analog models used to simulate and assess effects of turbulence on plankton rely on a one-dimensional simplification of the dissipative scales of turbulence, i.e., simple, steady, uniaxial shears, as produced in Couette vessels. There shear rates are constant and spatially uniform, and hence so is vorticity. Studies in such Couette flows have greatly informed, spotlighting stable orientations of nonspherical particles and predictable, periodic, rotational motions of steadily sheared particles in Jeffery orbits that steepen concentration gradients around nutrient-absorbing phytoplankton and other chemically (re)active particles. Over the last decade, however, turbulence research within fluid dynamics has focused on the structure of dissipative vortices in space and time and on spatially and temporally varying 2 vorticity fields in particular. Because steadily and spatially uniformly sheared flows are exceptional, so therefore are stable orientations for particles in turbulent flows. Vorticity gradients, finite net diffusion of vorticity and small radii of curvature of streamlines are ubiquitous features of turbulent vortices at dissipation scales that are explicitly excluded from simple, steady Couette flows. All of these flow components contribute instabilities that cause rotational motions of particles and so are important to simulate in future laboratory devices designed to assess effects of turbulence on nutrient uptake, particle coagulation and predatorprey encounter in the plankton. The Burgers vortex retains these signature features of turbulence and provides a simplified “cartoon” of vortex structure and dynamics that nevertheless obeys the Navier-Stokes equations. Moreover, this idealization closely resembles many dissipative vortices observed in both the laboratory and the field as well as in direct numerical simulations of turbulence. It is simple enough to allow both simulation in numerical models and fabrication of analog devices that selectively reproduce its features. Exercise of such numerical and analog models promises additional insights into mechanisms of turbulence effects on passive trajectories and local accumulations of both living and nonliving particles, into solute exchange with living and nonliving particles and into more subtle influences on sensory processes and swimming trajectories of plankton, including demersal organisms and settling larvae in turbulent bottom boundary layers. The literature on biological consequences of vortical turbulence has focused primarily on the smallest, Kolmogorov-scale vortices of length scale η. Theoretical dissipation spectra and direct numerical simulation, however, indicate that typical dissipative vortices with radii of 7η to 8η, peak azimuthal speeds of order 1 cm s-1 and lifetimes of order 10 s as a minimum (and much longer for moderate pelagic turbulence intensities) deserve new attention in studies of biological effects of turbulence.

    Description: The North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) is an interdisciplinary investigation to improve understanding of Earth's ocean ecosystem-aerosol-cloud system. Specific overarching science objectives for NAAMES are to (1) characterize plankton ecosystem properties during primary phases of the annual cycle and their dependence on environmental forcings, (2)determine how these phases interact to recreate each year the conditions for an annual plankton bloom, and (3) resolve how remote marine aerosols and boundary layer clouds are influenced by plankton ecosystems. Four NAAMES field campaigns were conducted in the western subarctic Atlantic between November 2015 and April 2018, with each campaign targeting specific seasonal events in the annual plankton cycle. A broad diversity of measurements were collected during each campaign, including ship, aircraft, autonomous float and drifter, and satellite observations. Here, we present an overview of NAAMES science motives, experimental design, and measurements. We then briefly describe conditions and accomplishments during each of the four field campaigns and provide information on how to access NAAMES data. The intent of this manuscript is to familiarize the broad scientific community with NAAMES and to provide a common reference overview of the project for upcoming publications.

    Description: In this paper we review on the technologies available to make globally quantitative observations of particles, in general, and plankton, in particular, in the world oceans, and for sizes varying from sub-micron to centimeters. Some of these technologies have been available for years while others have only recently emerged. Use of these technologies is critical to improve understanding of the processes that control abundances, distributions and composition of plankton, provide data necessary to constrain and improve ecosystem and biogeochemical models, and forecast changes in marine ecosystems in light of climate change. In this paper we begin by providing the motivation for plankton observations, quantification and diversity qualification on a global scale. We then expand on the state-of-the-art, detailing a variety of relevant and (mostly) mature technologies and measurements, including bulk measurements of plankton, pigment composition, uses of genomic, optical, acoustical methods and analysis using particles counters, flow cytometers and quantitative imaging devices. We follow by highlighting the requirements necessary for a plankton observing system, the approach to achieve it and associated challenges. We conclude with ranked action-item recommendations for the next ten years to move towards our vision of a holistic ocean-wide plankton observing system. Particularly, we suggest to begin with a demonstration project on a GO-SHIP line and/or a long-term observation site and expand from there ensuring that issues associated with methods, observation tools, data analysis, quality assessment and curation are addressed early in the implementation. Global coordination is key for the success of this vision and will bring new insights on processes associated with nutrient regeneration, ocean production, fisheries, and carbon sequestration.
