The present study discusses energy supply challenge and assesses renewable energy potential in the studied countries. Moreover, energy demand as well as demand projection is assessed until 2020. Resulting CO2-eq emissions are also projected. The study reveals that the countries under examination...

In many situations the applied researcher wants to combine different data sources without knowing the exact link and merging rule. This paper introduces a theoretical framework how two different regional administrative data sources can be merged. It presents different merging schemes based on...

Understanding mobile customer experience and behavior is an important task for cellular service providers to improve the satisfaction of their customers. To that end, cellular service providers regularly measure the properties of their mobile network, such as signal strength, dropped calls, call...

Environmental resources constitute the 'raw materials' for tourism. This sector represents the driving force behind the economy of small islands. The sustainable use and a rational policy of conservation of these resources are prerequisites to enable their full exploitation. However, island...

The SOEP success story was not conceivable at its inception. SOEP's institutionalization is therefore a lesson demonstrating that it is not always possible to say - as is so often required of research proposals today - how a project will develop before it has even begun, and what significance it...

The main aim of the present paper is to historically reappraise the development of the German Socio-Economic Panel Study (SOEP) in the 1990s after the first six waves had been collected. This development was closely connected to the opening of the Iron Curtain in Eastern Europe and the fall of...

A series of experiments was run in order to evaluate the usability of two different measurement approaches: ratings and ranks (pairwise comparisons). Respondents were asked to assess perceived characteristics (i.e. height and length) of different physical objects by using either a rating or a...

We study the interplay between scientific progress and culture through text analysis on a corpus of about eight million books, with the use of techniques and algorithms from machine learning. We focus on a specific scientific breakthrough, the theory of evolution through natural selection by...

This paper examines the trends in saving in New Zealand. It considers different sources of information about saving and highlights issues with the measurement of saving. Illustrations are provided of the impact of adjusting saving for both the effects of inflation and the inclusion of some items...
