The claim of a positive association between a firm's social assets and its innovative capacity is a widely debated topic in the literature. Although controversial, such an argument has informed recent innovation policy across Germany, increasingly directed to the cluster formation. In the light of the growing attention and financial efforts that cluster-based innovation policies are receiving, it is worth answering two main questions. First, are firms with a relatively high level of social capital likely to be more innovative? Secondly, do companies pursuing innovation in partnership innovate more? This paper empirically answers these questions by exploring a cross-sectoral sample of 248 firms based in the Jena region. On the one hand, the extent to which a firm is integrated in its community life does not contribute to an explanation of its innovative performance. On the other hand, directed cooperation with the specific goal of innovating shows a positive impact on innovative performance. However, the correlation between the extent of the network of co-innovators and firms' innovative capacity presents an inverted U-shaped relation: there is a threshold in the number of co-innovators justified by the costs of innovating by interacting. A policy lesson can be drawn from these findings: cluster-based policies are to be treated with caution as firms face costs of networking and not merely benefits.  相似文献

Many empirical studies in the fields of urban and environmental economics rely on the hedonic pricing framework. This paper draws attention to two important elements that are not covered by this theory: uncertainty and relocation costs. It develops a theoretical model where agents face uncertainty, but may accumulate savings as a form of self‐insurance. It shows that uncertainty pushes up relocation costs due to the option value of waiting, while self‐insurance helps to reduce this lock‐in problem. Moreover, the model suggests that the implicit price of environmental quality increases with uncertainty even if agents are risk‐neutral.  相似文献

This article explores the significance of the Danish flag in the formation of national identities during World War II and the immediate post-war period. During this dark and tumultuous period of Danish history, the flag was claimed by different groups with very different agendas, which in turn engendered differing conceptions of Denmark and Danishness. Three different themes are investigated in the article. The first regards the flag as a symbol of national continuity and endurance. From this angle, the flag functioned as a living, corporeal piece of history, which signalled that old Denmark would prevail, in spite of the crisis at hand. The second theme investigates the coupling of the flag with democracy during the 1943 elections. This event was hailed by the government as a major national celebration, with nationwide flagging for the democratic values of Denmark. At the same time, the elections were criticized as ‘un-national’, both by home-grown Nazis and the resistance movement. The third section dwells on the notion of martyrdom for the flag. This form of Danishness was not connected to peace-loving democracy, but woven into a martial discourse of sacrifice, honour and masculine heroism. Public worship of martyrdom was particularly intense in the early post-war era, when the flag was used to link ordinary Danes to the fallen heroes of the resistance movement. Thus, it was not the democratic spirit of 1943 that was celebrated after Liberation, but the martyrdom of fallen male resistance fighters, whose blood was evoked as the foundation of the re-born nation. The national memory of post-war Denmark, thereby, was based on the notion of a united people, who had stood firm and even been willing to die for the honour of their ancient flag.  相似文献

During the summer of 2008 archaeological excavations and geophysical prospection surveys were carried out in the mountain tundra region of north-eastern Sweden. The investigations focused on locating settlement remains connected with a Middle Neolithic tool production site discovered by archaeologists in 2001.  相似文献

Sadler, T., Kroh, A. &; Gallagher, S.J., March 2016. A review of the taxonomy and systematics of the echinoid genus Monostychia Laube, 1869 Laube, G.C., 1869. Über einige fossile Echiniden von den Murray Cliffs in Süd-Australien. Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften zu Wien, mathematisch-naturwissenschaftliche Classe. Abtheilung I 59, 183198. [Google Scholar]. Alcheringa 40, xxx–xxx. ISSN 0311-5518

A review of Monostychia, a stratigraphically important clypeasteroid echinoid genus in southern Australian Oligocene/Miocene strata, reveals uncertainty in relation to morphological features used in taxonomy. The result is that the exact systematic position of the genus remains unresolved at subfamily level. Monostychia and its type species, M. australis, are redescribed. Monostychia australis is restricted to the lower to middle Miocene Glenforslan Formation of the Murray Basin. Three other species currently within Monostychia, M. etheridgei, M. loveni and M. elongata, are discussed. Although it is concluded that M. etheridgei belongs in the genus and is a distinct species, the taxonomic position of M. loveni is questioned, and the validity of M. elongata as a separate species from M. australis remains uncertain. This work lays the foundation for further revisions of Monostychia with an expectation that such work will provide the basis for character determination that may be useful across other echinoid taxa.

Green areas are of high importance for the population in Germany. This is demonstrated by the representative outcomes of the latest Awareness-of-Nature survey for 2015. Most interviewees do not only value urban greens as personally important but also state that they perceive them as crucial for society and environment. The article focuses especially on the perception by people from different age groups and levels of education. It highlights that the strong awareness of the population provides a good fundament for the objectives and strategies of social, environmental and nature conservation policies.  相似文献

The question of how common usage could be constitutive for the meaning of linguistic expressions has been discussed by Renaissance philosophers such as Lorenzo Valla, and it also played an important role in Renaissance theories of juridical interpretation. An aspect of the analysis of common usage in Renaissance theories of juridical interpretation that concerns the role of presumption has not yet found much attention. Renaissance jurists such as Simone de Praetis, Nicolaus Everardus, and Aimone de Cravetta saw that both the usage of Latin by practitioners of law and the vernacular common usage of ordinary people often differed from the technical definition of legal concepts as laid down by ancient jurists or modern legislators. In some cases, they ascribed both to Latin and to vernacular common usage the power of changing the meaning of juridical terms. Still, they were aware of the fact that matters of common usage involve always a degree of uncertainty. The methodological notion of presumption is one of the concepts that figured most prominently in Renaissance approaches to the problem of uncertainty, and, in particular, it was applied in the analysis of meaning-change of legal concepts through common usage.  相似文献

Abstract

The notion of human dignity stands at the core of contemporary debates on rights, politics, and ethics. Many scholars consider the Renaissance discourse on dignity as one of its main contributions to the transition from the Middle Ages to modernity. This article examines the role of human dignity in the philosophies of Marsilio Ficino and Giovanni Pico della Mirandola. In their works human dignity relates both to freedom and to a Neo-Platonic ontology, which raises the question of how they reconcile these two possibly contradictory elements. I show that starting from the insight that human beings are “naturally” free and able to make right choices, Ficino and Pico argue that human dignity consists in the ability of humans to understand what is good and to act accordingly. I thus defend the thesis that their conception of human dignity is not modern because it liberates human beings from the “history of being” but rather because it paves the way for their liberation to become rational beings.  相似文献
