Ask questions, get sales : close the deak and create long-term relationships / Stephan Schiffman.
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
Endovascular Approaches in Aortic Surgery
No full textFilmed at the 2017 Aortic Live meeting in Essen, Germany, Mohamad Bashir of Barts Heart Centre in London, UK, moderates a discussion on treatments for aortic pathologies with Joseph Bavaria of the University of Pennsylvania in Philadelphia, USA, Heinz Jakob of the University of Essen in Germany, Tilo Kolbel of the University of Hamburg in Germany, Gebrine El Khoury of St-Luc Hospital in Brussels, Belgium, and Stephan Haulon of the Université Paris-Sud in Orsay, France.The variable nature of histologic, anatomic, and clinical presentations of aortic disease necessitate a careful consideration of available treatment options for this entity. Endovascular approaches have become the first-line therapy for descending thoracic aneurysms, with advancements in graft technology. The panelists discuss current and future applications of endovascular approaches to aortic disease, the decision between open and endovascular surgery, and the appropriate course of care for patients with Marfan syndrome.</p
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

Early experience with a modified preloaded system for fenestrated endovascular aortic repair
No full textObjective Preloaded endovascular delivery systems expand the anatomic eligibility for complex aortic repair by requiring only one iliac access vessel and providing a stable platform for guiding sheaths into challenging target vessels. This article reports the lessons learned and early clinical outcomes using a modified preloaded delivery system for fenestrated endovascular aneurysm repair (FEVAR) in three aortic centers in Europe. Methods From October 2015 to March 2016, consecutive patients presenting with extensive aortic aneurysm treated with a modified preloaded FEVAR were prospectively enrolled from three high volume European aortic centers. The new design is a modification of previous designs of preloaded fenestrated stent grafts and of the p-branch device platform. The technical details of implantation are described and perioperative outcomes, including the learning curve, are collected and reported. Results All patients (30 patients; 80% men; 70.2 years old) presented for nonurgent repair of either a type Ia endoleak (3/30; 10%), a type I-II-III thoracoabdominal (8/30; 27%), or a type IV thoracoabdominal or pararenal (19/30; 63.%) aneurysm repair of a mean size of 64 ± 13 mm using a custom made device. Primary technical success was achieved in 28 of 30 patients (93%) and assisted primary technical success in 29 of 30 patients (97%). The two technical failures included open conversion to repair a ruptured iliac artery and restenting of a dissected superior mesenteric artery which was recognized hours after the index procedure had finished. The mean procedure time was 277 ± 153 minutes, fluoroscopy time 79 ± 36 minutes, dose area product 112 ± 90 Gy cm2, and contrast volume 87 ± 46 mL. All renal fenestrations were successfully stented without type III endoleak on completion angiogram; the preloaded guiding sheaths were used for 53 of 58 renal arteries (91%). Challenges related to learning to the use of the modified preloaded system were experienced early and had no clinical consequences. Major complications occurred in seven cases (23%), including two perioperative deaths because of stroke and sepsis following primary conversion attributable to iliac rupture. There were no target vessel occlusions or type I/III endoleaks found on postoperative imaging. Conclusions Based on early experience, the modified preloaded system can be safely and effectively used during FEVAR, with good technical result and a short period of learning. This device expands treatment to patients with compromised iliac access, thus, additional patients and more follow-up will be required to determine unique risks of operating in this patient population
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
