No full textIncludes index.v, 168 pages ;In Ask Questions, Get Sales, the author and sales guru Stephan Schiffman helps readers boost their careers to the gold-medal level by teaching them how to strengthen their questioning skills during the sales process. The premise is simple yet effective: In order to be successful, salespeople need to change their mindset from "need-orientated" to "do-orientated". The message of the book centers around six core "do" questions: What do you do? How do you do it? When and where do you do it? Why do you do it that way? Who do you do it with? How can we help you do it better? With this indispensable guide in their briefcase, salespeople will have information at the ready to score big sales over the short term and the long term
Unemployment Benefits and Unemployment Rates of Low-Skilled and Elder Workers in West Germany: A Search Equilibrium Approach

To answer this question we estimate a version of the Burdett-Mortensen search equilibrium model and analyze how workers’ search behaviour responded to these reforms. We try both nonparametric and fully-parametric estimation methods and identify the cases in which the nonparametric approach cannot be applied. We find that the entitlement reforms are largely responsible for the increase of unemployment among unskilled workers

Measuring Vulnerability to Poverty Using Long-Term Panel Data
No full textMeasuring Vulnerability to Poverty Using Long-Term Panel Data Author & abstract Download & other version 16 References 4 Citations Related works & more Corrections Author Listed: Katja Landau (Georg-August-University Göttingen) Stephan Klasen (Georg-August-University Göttingen) Walter Zucchini (Georg-August-University Göttingen) Registered: Stephan Klasen Abstract We investigate the accuracy of ex ante assessments of vulnerability to income poverty using cross-sectional data and panel data. We use long-term panel data from Germany and apply di fferent regression models, based on household covariates and previous-year equivalence income, to classify a household as vulnerable or not. Predictive performance is assessed using the Receiver Operating Characteristics (ROC), which takes account of false positive as well as true positive rates. Estimates based on cross-sectional data are much less accurate than those based on panel data, but for Germany, the accuracy of vulnerability predictions is limited even when panel data are used. In part this low accuracy is due to low poverty incidence and high mobility in and out of poverty

Hybrid simulation of wake vortices of landing aircraft in a turbulent environment
No full textWake-vortex evolution during landing of a long range aircraft is investigated in a turbulent environment. The simulations cover final approach, touchdown on the tarmac, and the evolution of the wake after touchdown. An ambient turbulent crosswind and headwind field is generated in a pre-simulation. The wake is initialized using a RANS-LES coupling approach. The further development of the vortical wake is investigated by large-eddy simulation until final decay. Strong three-dimensional deformations appearing after touchdown and linkings with the ground are studied. The downwind vortex is strongly advected with crosswind and decays quickly. The interaction of plate line disturbances and end effects in a turbulent environment leads to irregular decay pattern
Development of an energy dispersive micro-X-ray fluorescence spectrometer for light element analysis
No full textMikro-Röntgenfluoreszenzanalyse (Mikro-RFA) ist eine etablierte analytische Methode, um die räumliche Verteilung der Haupt-, Neben- und Spurenelemente in einer Probe zu bestimmen. Die meisten Mikro-RFA-Spektrometer sind nicht in der Lage, leichte Elemente zu analysieren. Um den analytischen Bereich zu den leichten Elementen zu erweitern, wurde ein spezielles Mikro-RFA-Spektrometer entwickelt. Es bietet verbesserte Anregungs- und Detektionsbedingungen, welche für die Analyse leichter Elemente erforderlich sind. Die Komponenten das Spektrometers wurden sorgfältig ausgewählt, damit sie bei leichten Elementen die optimale Leistung liefern. Um die Absorption der niederenergetischen Strahlung zu vermeiden, arbeitet das System unter Vakuum. Der Messablauf geschieht automatisiert von einer für dieses Spektrometer speziell entwickelten Software. Das Design und der Aufbau des Spektrometers, sowie die Entwicklung der Software erfolgten vom Autor. Die mechanischen Komponenten wurden in der Werkstatt des Atominstituts gefertigt. Das Spektrometer verwendet eine luftgekühlte Niederleistungs-Mikrofokus-Röntgenröhre mit Mo-Anode, welche die Mo-L Linien fu-r eine besonders effiziente Anre- gung der leichten Elemente verwenden kann. Der kleine Anodenbrennfleck (50µm) ist ideal für die Fokussierung der Röntgenstrahlen mittels einer Polykapillaroptik auf die Probe. Die Probe kann mit einer motorisierten Probenbühne bewegt werden. Ein hochauflösendes Videomikroskop mit kleiner Schärfentiefe (3,5 µm) wird verwendet, um die Probe exakt zu positionieren. Die Fluoreszenzstrahlung wird von einem Si(Li)-Detektor mit ultradünnem Polymerfenster (340 nm) detektiert. Dieses spezielle Fenster erlaubt es, die niederenergetische Fluoreszenzstrahlung leichter Elemente zu detektieren. Verschiedene Proben wurden gemessen, um das Spektrometer zu testen und zu charakterisieren. Die Spotgröße wurde mittels eines Scans über einen 10µm Cu-Draht bestimmt und ergaben 31 µm für Mo-K-, 44 µm an der Cu-K Kante und 71 µm an der Cu-L Kante. Die unteren Nachweisgrenzen liegen im pg-Bereich pro Spot bzw. ppm- Bereich. Flächenscans von einem kleinen Laserausdruck und einem NaF-Tropfen zeigen die Fähigkeit, Elementverteilungen aufzunehmen und demonstrieren die Analyse leichter Elemente.Micro X-Ray fluorescence (micro-XRF) is a well established analytical method to determine the spatial distribution of major, minor, and trace elements in a sample. Most micro-XRF spectrometers are not capable of analyzing light elements. A special micro-XRF spectrometer has been designed in order to extend the analytical range down to light elements. The new spectrometer offers improved excitation and detection conditions necessary for light element analysis. The components for the spectrometer have been carefully chosen for optimal performance when measuring light elements. In pursuance to eliminate absorption of the low energy radiation, the system operates under vacuum condition. Sample mapping is automated and controlled by specialized computer software developed for this spectrometer. The design and setup of the spectrometer, as well as the development of the software were done by the author. The mechanical components were manufactured in the Atominstitut workshop. The system uses an air cooled low power microfocus X-Ray tube with Mo-anode. This allows the Mo-L lines to be used for particularly efficient excitation of light elements. The small spot (50 µm) is ideal to be used in conjunction with a polycapillary optic. The X-Ray optic focuses the exciting radiation onto the sample. The sample can be moved by a motorised sample stage. A high resolution video microscope with small depth of field (3.5 µm) is used to position the sample accurately. The fluorescence radiation is detected using a Si(Li) detector with ultra thin (340 nm) window. This special window allows the low energy fluorescence radiation of light elements to be detected. Several different samples were measured to test and characterize the spectrometer. The spot size has been determined by scans across a 10µm Cu wire, which yielded results of a spot size of 31 µm for Mo-K-, 44 µm at the Cu-K edge and 71 µm at the Cu-L edge. Lower limits of detection were obtained in the pg range for each spot as well as ppm. Area scans of a small laser print and a NaF droplet were performed to show mapping capabilities and light element analysis
On the Problem of Stephan Javors’kyj’s Homiletics
No full textThe author analyses the content of the unique manuscript which contains at least 70 unpublished sermons written by Stephan Javors’kyj when he was still in Ukraine (ms. 1592 of the Russian state historical archive in S. Petersburg). She tries to explain some latent significations of his homilies and underlines how urgent it is to undertake scientific publications of these and other works by Javors ’kyj, which would allow to give a completely different image of this outstanding personality of Ukrainian literary Baroque.Авторка аналізує зміст унікальної збірки, яка містить щонайменше 70 неопублікованих гомілій Стефана Яворського (рукопис № 1592 Російського державного історичного архіву в Санкт-Петербурзі), намагається пояснити деякі приховані значення його проповідей та наголошує на потребі сучасного видання праць Яворського, що дозволило б подати цілком відмінний образ цієї видатної особистості в українському літературному Бароко
