The number of aspiring entrepreneurs in high-tech industries who successfully complete the transition from a nascent start-up project towards an operational new venture is comparatively low in Germany. Since the mid-1990s, policy-makers have initiated numerous start-up competitions (SUCs or business plan competitions) to facilitate this important step in the venture creation process. SUCs have two key objectives. They are aimed at increasing start-up activity by motivating potential entrepreneurs, while they should also help to increase the likelihood of subsequent entrepreneurial success through providing necessary entrepreneurial skills to prospective entrepreneurs. With our explorative study, we provide the first comprehensive empirical evidence from a cross-sectional survey of existing SUCs in Germany. Overall, 71 SUCs are identified which are analysed regarding their development, regional distribution, and main structural characteristics. Finally, we outline an agenda of future research questions concerning the effectiveness and efficiency of SUCs as an instrument of entrepreneurship policy.  相似文献

In the period 1909-1927, new laws concerning divorce and marriage were enacted by the Scandinavian countries. Both at the time and more recently, these laws were considered as "liberal" as they promoted greater freedom to divorce based on individuality and gender equality. In this article, the authors first analyze the changes in these Family laws in the early twentieth century. Then, the authors study the effect of these laws on divorce and marriage patterns. As these laws did not modify the trend in divorce rates, the authors ask why this was the case. The authors' conclusions are that the laws were more concerned with preserving the sanctity of marriage and maintaining social order than with promoting individual freedom and gender equality.  相似文献

During the Neolithic, obsidians of the Monte Arci (Sardinia) volcanic complex were by far more used in the northern Tyrrhenian area than those of the three other source-islands (Lipari, Palmarola, Pantelleria) in the western Mediterranean. It is shown that merely determinations of content for six major elements with a scanning electron microscope by energy dispersion spectrometry (SEM-EDS) are sufficient to distinguish the four types of Monte Arci obsidians. Because of the compositional similarities between these obsidian types, a multivariate analysis is recommended in provenance studies. Although SEM-EDS, electron microprobe-wavelength dispersion spectrometry (EMP-WDS) and particle induced X-ray emission (PIXE) give essentially concordant results in the determination of these six element contents, subtle technique-related biases prevent the combination of SEM-EDS, EMP-WDS and PIXE data on source samples for provenance purposes. An SEM-EDS test-study reveals the first occurrence of obsidians of Lipari for the A Fuata Middle to Late Neolithic site of NW Corsica (north of Sardinia), in addition to the usual Monte Arci obsidians. Similar to EMP-WDS, the SEM-EDS technique requires only millimeter-sized fragments.  相似文献
