The regional variation of new technology based firms in Austria
During the last two decades the role of new business start-ups has gained a growing interest both from regional economics as well as from (regional) economic policy. It was recognized that not only the large Galbraithian enterprise is the driving force in processes like employment growth or structural economic change, but also small and often new or young firms are playing an active role. In the 1980s so called new technology based firms (NTBFs) gained considerable attention. It has been argued that the Schumpeterian entrepreneur is an important force for the implementation of new ideas into the market place, often via the formation of NTBFs. In our paper we analyse the structure and the regional variation of new business formation in the high technology sector in Austria. Using a definition based upon the OECD we differentiate the high tech sector in (i) top technology, (ii) higher technologies and (iii) technology orientated services. We demonstrate the relative importance of these groups for the total population of new business start-ups in Austria in the time period ot 1990-1994 as well as for certain sub-populations like manufacturing and services. The main part of our paper discusses the regional variation of NTBFs using the framework of the well known urban incubator hypothesis. It is expected that metropolitan and urban regions have a higher orientation towards high tech (what means the proportion of NTBFs) than the rural or hinterland regions. An additional part of our paper deals with the question wether NTBFs play an important role in the process of structural change of regional economies as has been postulated by various authors during the last couple of years.

Sustainability by Reduced Energy Consumption during Manufacturing: The Case of Cosmetic Emulsions
Energy input in emulsion manufacturing comprises thermal and mechanical energy, with thermal energy being predominant. In terms of raw material selection, there is a widely accepted belief that natural formulations are more “eco-friendly” than their standard (not natural) counterparts. The aim of this study was to compare the energy consumption and subsequent carbon footprint resulting from the production of two main emulsion types, each represented by its standard and natural variant and made by using different manufacturing processes (hot, hot-cold and cold). This resulted in six samples of oil-in-water (O/W) and water-in-oil (W/O) emulsion types, respectively. Scale-down calculations were used to establish the required homogenisation time and speed of the laboratory homogeniser, necessary to achieve the same shear rates as the chosen industrial vessel. The resulting emulsions were characterised using rheological and textural analysis. The six emulsions within each emulsion type have exhibited sufficiently similar characteristics for the purpose of carbon footprint comparisons. Calculations were conducted to quantify the energy input of hot and hot-cold procedures, followed by cradle-to-gate life cycle analysis (LCA). Energy calculations demonstrated that the hot-cold manufacturing process saved approximately 82% (for O/W) and 86% (for W/O) of thermal energy in comparison to the hot process. LCA has shown that the effects of using natural instead of standard ingredients were negative, i.e., it led to a higher carbon footprint. However, it was dwarfed by the effect of the energy used, specifically thermal energy during manufacturing. This strongly indicates that the most efficient way for companies to reduce their carbon footprint is to use the hot-cold emulsification process
Not Just Babble: A Voluntary Contribution Experiment with Iterative Numerical Messages
When subjects can make non-binding announcements of possible contributions to a public good numerically, there is no effect on average level of contributions in a public goods experiment relative to play without announcements. But a detailed analysis of this experiment shows that pre-play announcements increased the variance of achieved cooperation among groups, leading both to more highly cooperative groups and to more thoroughly uncooperative groups than in a treatment without announcements. We also add a treatment in which subjects can select a statement of (non-binding) “promise” to contribute a certain amount and we find that even though subjects were instructed that promise statements were not binding, the ability to issue them significantly increased both contributions and earnings in a treatment that includes costly punishment opportunities, although not in a treatment without punishment
Predominance of secondary organic aerosol to particle-bound reactive oxygen species activity in fine ambient aerosol
Reactive oxygen species (ROS) are believed to contribute to the adverse health effects of aerosols. This may happen by inhaled particle-bound (exogenic) ROS (PB-ROS) or by ROS formed within the respiratory tract by certain aerosol components (endogenic ROS). We investigated the chemical composition of aerosols and their exogenic ROS content at the two contrasting locations Beijing (China) and Bern (Switzerland). We apportioned the ambient organic aerosol to different sources and attributed the observed water-soluble PB-ROS to them. The oxygenated organic aerosol (OOA, a proxy for secondary organic aerosol, SOA) explained the highest fraction of the exogenic ROS concentration variance at both locations. We also characterized primary and secondary aerosol emissions generated from different biogenic and anthropogenic sources in smog chamber experiments. The exogenic PB-ROS content in the OOA from these emission sources was comparable to that in the ambient measurements. Our results imply that SOA from gaseous precursors of different anthropogenic emission sources is a crucial source of water-soluble PB-ROS and should be additionally considered in toxicological and epidemiological studies in an adequate way besides primary emissions. The importance of PB-ROS may be connected to the seasonal trends in health effects of PM reported by epidemiological studies, with elevated incidences of adverse effects in warmer seasons, which are accompanied by more-intense atmospheric oxidation processes
