Why do Employees Leave Their Jobs for Self-Employment? – The Impact of Entrepreneurial Working Conditions in Small Firms

Based on the finding that entrepreneurs who found new firms tend to work as employees of small rather than large firms prior to start-up, we test how different working conditions, which enhance entrepreneurial learning, affect their decision to become entrepreneurs when moderated by firm size. Based on data of the German Socio-Economic Panel (SOEP), we find a significant relationship between entrepreneurial learning (extracted in an orthogonal factor analysis based on twelve working conditions as proxy for entrepreneurial human capital and work experience) and firm size when predicting the probability of leaving paid employment for self-employment. We think, that this is a special kind of knowledge spillover. We also control for other aspects such as gender, age, wage, etc. – factors that may potentially influence the decision to become self-employed. Thus, our analysis sheds new light onto the black box of SMEs as a hotbed of new start-ups.Entrepreneurship, Occupational Choice, Working Conditions, Human Capital

Lacerta kulzeri – filogenetički odnosi indicirani DNA sekvencijama

In order to resolve the relationships of Lacerta kulzeri, parts of mitochondrial genes for 12S rRNA and 16S rRNA of samples of the following species were sequenced: Gallotia stehlini (as an outgroup), Lacerta trilineata, L. cappadocica, L. fraasii, L. danfordi, L. rudis, Podarcis peloponnesiaca, as well as representatives of different populations of L. laevis and L. kulzeri. Sequence analysis clearly shows a close relation between L. laevis and L. kulzeri and no close relation of these species to any other representative of the lizards examined. The other species also show themselves to be representatives of very distinct lacertid groups. The resulting sequence differences within L. kulzeri and L. laevis, respectively, are very high in relation to those between the two species, and they are higher than one would expect for species with small areas.Da bi se razriješili odnosi Lacerta kulzeri, sekvencionirani su dijelovi mitohondrijskih gena za 12S rRNA i 16S rRNA uzoraka sljedećih vrsta: Gallotia stehlini (kao outgroup), Lacerta trilineata, L. cappadocica, L. fraasii, L. danfordi, L. rudis, Podarcis peloponnesiaca, kao i predstavnici različitih populacija L. laevis i L. kulzeri. Analiza sekvenci jasno pokazuje blisku vezu L. laevis i L. kulzeri, a nikakvu blisku vezu tih vrsta s ostalim ispitanim vrstama guštera. Ostale vrste također su se pokazale kao predstavnici vrlo različitih lacertidnih grupa. Konačne razlike u sekvencijama unutar L. kulzeri, odnosno, L. laevis su vrlo visoke u odnosu na one između dviju vrsta, i više su nego što bi se očekivalo za vrste s malim arealima

Raspodjela ekoloških niša između sedam simpatričkih lacertidnih gušterica u Peloponeškom gorju

All seven lacertid species recorded in the Peloponnese can be found in a very small area in the Arcadian highlands on the Peloponnese peninsula. Only one example of such unique diversity in such a small area has been described in the Mediterranean region before. This density requires the occupation of different restricted ecological and ethological niches by all seven species and therefore the habitats have to be diverse. Niche segregation, ecological demands and the ethological differences between the species are discussed in relation to this habitat diversity.Svih sedam lacertidnih vrsta zabilježenih za Peloponez mogu se naći na vrlo malom području u Arkadijskom gorju na poluotoku Peloponezu. Dosad je na području Sredozemlja poznat samo jedan primjer takve jedinstvene raznolikosti na tako malom prostoru. Takva gustoća zahtijeva zauzeće različitih ograničenih ekoloških i etoloških niša sa strane svih sedam vrsta i zbog toga staništa moraju biti raznolika. U radu se raspravlja o toj podijeljenosti niša, kao i o ekološkim zahtjevima i etološkim razlikama među vrstama, u odnosu na raznolikost staništa

Envisioning Unity: The Media Discourse in South Korea and Germany on National Unity. A Longitudinal Study on Emerging Transnational Public Spheres

Using the example of the discourse on national unity in Germany and South Korea, this article examines the formation of transnational public spheres along long-wave political issues. It explores to what extent a similar political challenge of two states is conducive to the formation of a transnational public sphere. The findings of a qualitative analysis of frames in the reporting of South Korean and West German leading media on the process of German unification from 1989 to 1991 as well as the initiatives of South Korean President Moon Jae-In for peace and unification on the Korean peninsula in 2018 and 2019 are discussed. The study reveals indications for the emergence of a trans-national public sphere with regard to all important indicators. However, this appears to be fragile and strongly driven by the fall of the Berlin Wall as a key event with global impact

Franz Julius Ferdinand Meyen: gefördert und frühvollendet. Zwischen Poesie und totem Zoo

Zusammenfassung Franz Ferdinand Julius Meyen (1804–1840) veröffentlichte auf sehr vielen Gebieten der Biologie wichtige Arbeiten, vor allem in Botanik und Zoologie. Mit Unterstützung Alexander von Humboldts gelang es ihm, auf dem Forschungsschiff „Prinzess Louise“ anzuheuern und als Schiffsarzt an einer mehrjährigen Weltreise teilzunehmen. Humboldt, der einige Regionen ebenfalls besucht und erforscht hatte, unterstützte seinen jungen Kollegen bei der Vorbereitung seiner Reise. Meyen veröffentlichte seine Reiseergebnisse bereits kurz nach seiner Rückkehr, gefördert von Christian Gottfried Nees von Esenbeck (1776–1858), sowohl als zweiteiligen historischen Reisebericht als auch in sieben Einzelabhandlungen. Einige Ergebnisse, die er, schwerkrank, nicht selbst verwerten konnte, übergab er noch bei Lebzeiten zur Bearbeitung an Spezialisten, andere wurden posthum von Mitgliedern der Leopoldina publiziert. Meyen brachte u. a. eine umfangreiche Sammlung an Vogelpräparaten mit, zu denen auch das Erstbeschreibungsexemplar des von ihm so genannten Spheniscus humboldti (Trivialname: Humboldt-Pinguin) gehört. Résumé Franz Ferdinand Julius Meyen (1804 –1840) publia des ouvrages majeurs dans plusieurs champs de biologie, notamment dans la botanique et la zoologie. Ses recherches ont été appréciées à l’époque même, l’admission à l’Académie Leopoldina en fait preuve. Grâce au soutien d’Alexander von Humboldt, Meyen parvint à prendre part au tour de tour de monde du bateau de recherche prussien « Prinzess Louise » en tant que médecin de bord. Ayant déjà exploré quelques-unes de ces régions lors de son voyage américain, Humboldt seconda Meyen dans la préparation de l’expédition. Meyen publia les résultats du voyage très peu de temps après son retour, avec le soutien de Gottfried Nees von Esenbeck (1776–1858). Il rédigea non seulement une relation historique du voyage, mais encore sept mémoires à part. Déjà gravement malade, Meyen remit des résultats encore inédits aux spécialistes dans les champs respectifs, autres découvertes furent publiées par membres de la Leopoldina. Meyen rapporta notamment une collection d’oiseaux très riche en nombre de spécimens, dont l’exemplaire de la première description de Spheniscus humboldti (nom commun : Manchot de Humboldt). Summary Franz Ferdinand Julius Meyen (1804–1840) has published important results in several fields of biology, especially botany and zoology. By support of Alexander von Humboldt Meyen got the chance to accompany the expedition on the vessel „Princess Louise“ as a medical doctor. Alexander von Humboldt, who had visited many years before some of the areas gave him assistance during the preparation for the journey. Meyen published his results shortly after his return in a so called „historical report” on his travel what was published in two parts as well as in special articles. Some of his results he handed over to specialists, some of it has been reported post mortem by members of the Academy Leopoldina. Meyen brought an impressive collection of prepared birds to Berlin, including the type specimen of Spheniscus humboldtii (so called Humboldt-penguin)
