Why do so many companies fail to make use of the energy-saving technologies which are available? Dutch researcher Mark Koetse used a meta-analysis of various empirical studies to assess the relevance of two possible explanations.
Meta-analysis is a research method that has been gradually gaining ground within economics since the mid-1980s. The doctoral research of Mark Koetse focused on the problems associated with this methodology. That is why in his thesis he described the negative effects of several frequently-occurring problems using simulation techniques and investigated the extent to which these effects could be mitigated using standard models in meta-analysis.
Koetse analysed the outcomes of empirical studies on the investment behaviour of entrepreneurs to find out whether uncertainty exerts a positive or negative influence on investments within companies. Very few of these studies revealed a positive and statistically significant relationship. A further quantitative analysis demonstrated that the variation in empirical outcomes can largely be explained by differences between the underlying studies. Furthermore, the meta-analysis suggests, albeit indirectly, that the uncertainty about, for example, energy prices possibly has an inhibitory effect on investments in energy-saving technologies.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
