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
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

Computational Supporting Information for Methane Adsorption on Heteroatom-Modified Maquettes of Porous Carbon Surfaces
No full textThis dataset is an extensive computational supporting information for the first manuscript of a series of reports from the collaborative work of the carbon materials laboratory of Prof. Nicholas Stadie and the computational laboratory of Prof. Robert Szilagyi at Montana State University. The dataset provide atomic-scale insights into the structure and properties of amorphous carbon materials for reversible gas storage applications. The current report is focused on modeling methane adsorption on zeolite-templated carbon through invoking the concepts of maquettes: simplified models with essential functionalities preserved of the real system. We employed a converging series of explicitly correlated MO theory and density functional theory.
The theoretical approach employed is based on our previous publications

The level of theories considered here are consistent with an earlier study that was carried out independent from our focus

Moreover, key experimental data are taken from
Stadie N.P., Murialdo M., Ahn C.C., Fultz B.: Unusual Entropy of Adsorbed Methane on Zeolite-Templated Carbon Journal of Physical Chemistry C, 2015, 119(47), 26409-26421 DOI: 10.1021/acs.jpcc.5b05021.
In addition to a comprehensive evaluation of the methane adsorption on pure-carbon maquette surface, we extended the adsorption studies to B- and N-doped adsorbents. We found consistent preference for N-doped materials for methane storage. In addition to discussing energy differences and structural variations as a function of the nature of dopant, we uncovered details of the electronic structure of methane interactions and its variability along the series of C, B, and N. The predicted heat of adsorption values are now informing on-going experimental synthetic work in the Stadie laboratory toward the optimization of gas storage materials.
The results reported in the manuscripts stimulate extension of our work to larger maquettes of porous carbon surfaces with synthetically relevant functional groups, alternative ring sizes, curvature, and other heteroatom substitutional dopants. An additional notable merit is our effort to provide a clear thermodynamic connection among microscopic and macroscopic observables related to physical properties of gas storage materials and interfaces.R.R., E.T., and N.S. are supported by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) under the Hydrogen and Fuel Cell Technologies and Vehicle Technologies Offices (DE-EE0008815).
