Abstract. The paper proposes a human capital‐based model of choice between paid employment and entrepreneurship that can give rise to multiple equilibria in occupational structure. The model is consistent with evidence of pronounced, persistent, and hitherto unexplained regional variations in entrepreneurship. Whether multiple equilibria emerge is shown to depend on the occupation‐specific productivity of human capital and the costs of human and financial capital. The paper goes on to discuss the implications for governments seeking to promote entrepreneurship as a tool of regional development policy.  相似文献

Globalization emerged as the buzzword of the 1990s, and, at the dawn of a new millennium, it continues to transfix academics, the media and policy-makers alike. However, one of the key gaps in the research into the process(es) of globalization has concerned its historical identity: the story (and analysis) of its origins, its development and mutation over time, and the continuities and differences between past and present. In this article the author sketches a typology of claims made about the historical identity of globlization in the current literature, and points to some unexplored and fruitful avenues of enquiry. Following this, two recent books are reviewed which attempt, in different but complementary ways, to deepen our understanding of globalization in history. The article concludes with a call for further research on this and related topics.  相似文献

Drawing on poststructuralist political ecology, the narratives of two struggles about siting a superquarry are examined to elucidate the complex articulations of community, nature, resistance and identity in play in public debates. Focusing on the discursive formulations of the quarry in the expert language, as well as in the arguments of both local proponents and opponents of the quarries, shows the importance of ontological categories in "environmental" siting disputes. In Harris, these themes rearticulate the histories of dispossession, crofting and religion, as well as complex layers of geographical identity in the various claims to community. In Cape Breton, the rethinking of aboriginal Mi'kmaq identity was stimulated by revived interest in the religious traditions linked to the sacred site near the proposed quarry. In light of these findings, the complexity and active rearticulation of local "community" as political resistance are emphasised and the difficulties of thinking about sustainability highlighted.  相似文献

Following earlier examples of mapping the subsurface of shell bearing sites using augering, we employ percussion coring to identify early Holocene shell midden components at two types of sites on the Northwest Coast of North America. We describe a method for mapping subsurface components at shell bearing sites including basal deposits, paleosols and transitions between distinct cultural components. Our research was undertaken for the purpose of identifying early Holocene shell middens above the modern shore, and as components below large shell midden villages. Our results augment the developmental trajectory of shell middens on the Northwest Coast by suggesting that pre-5000 BP forms of these sites may be more common than previously thought. In light of these results, we argue that the Northwest Coast cultural historical sequence, which locates an increase in the number and rate of accumulation of shell middens beginning 5000 years ago, to be premature. However, there are insufficient data from shell middens in the early Holocene, a sampling problem that the percussion coring methods described here can address.  相似文献

Memories of headhunting, and ritual re‐enactments of those former violent practices, are still politically meaningful in contemporary Oceania and Southeast Asia. The case of the Sejiq of Taiwan illustrates how such practices were transformed and eventually terminated as a result of colonialism and the incorporation of formerly stateless peoples into new political institutions. Headhunting was once an expression of the sacred law of Gaya, as both a reinforcement of territorial boundaries and a way of settling legal disputes within communities. It expressed tensions in a ‘reverse dominance hierarchy’ by which some men tried to consolidate political power, but were usually deterred by a strong egalitarian ethos. During the period of Japanese administration (1895–1945), new technologies made headhunting more efficient, but it became more difficult for this formerly egalitarian people to avoid the political coercion of would‐be leaders. Contradictions between headhunting as the implementation of Gaya and headhunting as a consolidation of political power — itself viewed as a violation of that Law — eventually led to the abandonment of headhunting. Local leaders found new ways to seek political power, including in the ritual re‐enactment of the very same practices used by their ancestors, but continue to be resisted by ordinary people with an egalitarian ethos.  相似文献

Through use of methodology common in sedimentary geology, we apply U–Pb ages of detrital zircons to source nonlocal temper sand in an ancient ceramic assemblage recovered from Roviana Lagoon of the New Georgia Group in the Solomon Islands. Most potsherds from the Roviana Lagoon contain local volcanic sand as temper, but a small number of sherds contain anomalous granitic temper sand that does not appear to be local. To determine the origin of the anomalous temper, ages of zircons from the anomalous Roviana sherds are compared with ages of zircons in materials from Lizard Island off the Queensland coast and in sand from Muyuw Island in the Solomon Sea where generically similar granitic sands occur. U–Pb analyses of grains from the Roviana sherds yield Middle Miocene ages, while analyses of grains from Lizard Island granitic bedrock, sand, and local potsherds yield much older Permian-Triassic ages, disproving any possibility that the Roviana sherds were derived from Lizard Island, but suggesting local production of the Lizard Island sherds. Ages of grains in a sand sample from Muyuw Island are nearly identical to the ages of grains in the Roviana sherds. All grains in the Muyuw sand are Middle Miocene in age, overlapping closely with the Roviana age population. This strong similarity in detrital zircon signals indicates that the Roviana temper was likely derived from Muyuw Island sands. Our test case for the use of U–Pb ages of detrital zircons in sourcing temper sands is of only regional significance, and not of intrinsic global interest. The methodology, however, should find wide applicability for sourcing temper sands in many parts of the world, for it provides more specific data for the origins of tempers than either petrographic or chemical analysis.  相似文献

African clothing industries have declined since the implementation of economic liberalization policies in the early 1980s whilst used‐clothing imports to Africa have increased. The general effects of economic liberalization on African clothing industries are well documented, although little research has been conducted on the particular impact of increased imports of second‐hand clothes on the local manufacturing sectors. Whether these two processes are causally related is difficult to determine due to limitations in official data sets. In this article, the used‐clothing trade is explored in detail and a broad range of cultural and local economic processes are investigated. Trends such as declining local purchasing power and the opening of African markets to cheap new clothing imports, as well as imports of used‐clothing, are examined, along with the converse boost to African clothing export production resulting from preferential trade agreements in the 2000s. With respect to the differential legal and illegal imports of second‐hand clothing to selected African countries, it is demonstrated that official trade data sets often fail to capture the nuances of contemporary social and economic processes.  相似文献
