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

Biphasic ceramic bone substitute in combination with fibrin for the therapy of benign bone tumors and tumor-like lesions
No full textKnochendefekte, die in der Behandlung von gutartigen Knochentumoren und tumorähnlichen Läsionen entstehen, stellen ein klinisches Problem mit limitierten Therapieoptionen dar. In der Regel werden diese Defekte mit autologem Knochen aufgefüllt. Die Gewinnung von autologem Knochen, z. B. vom Beckenkamm ist jedoch quantitativ limitiert und häufig mit Komplikationen verbunden. Aus diesem Grund wird versucht, synthetische Knochenersatzmaterialien mit ähnlichen Eigenschaften, wie denen des autologen Knochens, zu entwickeln. In der vorliegenden prospektiven Studie wurde die Anwendung einer biphasischen Keramik aus 60% Hydroxylapatit und 40% beta-Tricalciumphosphat in Verbindung mit verdünntem Fibrinkleber für die Therapie von gutartigen Knochentumoren und tumorähnlichen Läsionen bei 51 Patienten untersucht. Hierfür wurden die Röntgenbilder analysiert und das Resorptionsverhalten beurteilt. Eine komplette Resorption wurde anhand der radiologischen Verläufe in keinem Fall beobachtet. Die günstigsten Voraussetzungen für eine Resorption wurde bei kleinen Defekten (< 10,5 cm³) beobachtet (p < 0,05). Die übrigen Einflussgrößen zeigten nach einer Nachuntersuchungszeit von bis zu 56 Monaten keine statistisch signifikanten Unterschiede. In der histologischen Untersuchung eines Präparates bei einer Revision wurde Knochenneubildung auf dem Knochenersatzmaterial nachgewiesen. In diesem Fall war das Knochenersatzmaterial noch nachweisbar. Die Verwendung des Materials ist klinisch einfach und sicher. Die aufgetrete-nen Komplikationen entsprechen in ihrer Häufigkeit den zu erwartenden postoperativen Komplikationen und sind mit den Angaben der Literatur vergleichbar. Es wurden keine postoperativen Frakturen oder Beeinträchtigung des Längenwachstums von Röhrenknochen beobachtet. In einem Fall musste aufgrund eines intraossären Ganglions eine operative Revision erfolgen. In der histologischen Aufarbeitung dieser Biopsie konnte Knochenneubildung und Osseointegration sowie eine partielle Resorption des Knochenersatzmaterials nachgewiesen werden. Die Verwendung des Knochenersatzmaterials wird von den Patienten überwiegend als positiv beurteilt. Zusammenfassend ist das verwendete Knochenersatzmaterial eine einfach und sicher anzuwendende Alternative zu autologem Knochen in der Therapie von gutartigen Knochentumoren und tumorähnlichen Läsionen.Bone defects resulting from tumor resection represent a challenge facing limited therapeutic options. Most commonly, defects are reconstructed with autologous bone graft which is associated with limited availability and donor site morbidity. Therefore, recent research has focused on synthetic biomaterials as bone graft substitutes. In the present study, a biphasic ceramic consisting of 60% hydroxyapatite and 40% beta-tricalciumphosphate combined with a fibrin sealant was used to reconstruct defects in 51 patients after resection of benign bone tumors or tumor-like lesions. Radiologic analysis showed complete bony defect consolidation in 50 out of 51 patients after up to 56 months. No postoperative fractures were observed. Revision surgery had to be performed in one case. Histological analysis showed new bone formation and good biocompatibility and osseointegration of the implanted material. Subjective patient satisfaction after application of bone substitute was predominantly positive. In summary, the biphasic ceramic in combination with fibrin sealant was proven an effective, safe and easy to handle alternative to autologous bone graft eliminating the risk of donor site morbidity for the patient
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
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
