Safeguarding biodiversity has been one of the most important issues in environmental and forest policies since the 1990s. In Southern Finland, decisions concerning further actions for the preservation of forest biodiversity will be made in the coming years. To support policy making, we present a multi-regional model that is applicable in determining the economically optimal regional allocation of conservation sites. Three habitat quality models are evaluated to calculate habitat quality indices used as a surrogate for a biodiversity value in a forest sector model. The scenarios presented provide information about the economic impacts of conservation choices on the forest sector. The overall economic impacts of conservation depend on its scale and regional allocation. Conserving land with high biodiversity value can have less adverse impact on the forest sector than conservation of typical commercial forest sites. When optimizing conservation set-asides, we found that set-asides targeted to certain regions possessing higher/lower than average relative share of ecologically valuable land, caused lower/higher adverse economic impacts on the forest sector. Because it is expensive to search land suitable for conservation, these regions could be respectively favoured/avoided when asking forest owners to offer their land for the new conservation program in Southern Finland, which will be based on voluntariness.  相似文献

ABSTRACT

Innovative firms often involve customers in their product development to drive innovation outcomes. However, few have empirically examined how this division of innovative labour affects innovation performance. Drawing on prior studies and the knowledge-based theory of the firm, we theorise conditions under which customer codevelopment benefits innovation performance. By examining panel data from Swiss firms, we provide the first empirical account of the performance effects of customer codevelopment based on a large-scale survey sample. We find that a firm's absorptive capacity reinforces the relationship between customer codevelopment and innovation performance. We elaborate on the implications of these findings for the literatures on customer codevelopment and open innovation.  相似文献

Partnership in education looks at one technical college's approach to meeting the demand for trained workers in central service and materiel management. This article examines the partnership formed between a college, area health care facilities, and industry to design, develop, and implement a central service materiel management program.  相似文献

Nanotechnologies are becoming a larger presence in everyday life and are viewed by governments and economic actors as a key area for development. The theory of social representations suggests that specialist views eventually disseminate to shape representations among the public. Yet nanotechnologies remain relatively little known to the general public. The media emphasize potential benefits, while potential risks get less attention. The literature has not yet addressed whether representations by a well-informed population (scientists) are indeed structured in terms of the risk–benefit polarity that dominates research framing to date. We attempted a systematic assessment of how background knowledge about nanotechnology may influence experts’ perception. Study 1 delivered the first demonstration derived from a qualitative analysis confirming the existence of a polarized representation of nanotechnologies, contrasting opportunity (medical, economic, and technological) and risk. Interestingly, risk was distinguished at two levels: that associated with nanomaterial characteristics (toxicity, reactivity) and at the larger scale of impact (health, environment, legislation). Does this polarity indicate a ‘yes, but’ logic (nanotechnology carries opportunity but also risk), or two clusters of specialists (sensitive, respectively, to opportunity or to risk)? Study 2 surveyed a larger sample of experts who self-described their scientific background and role viz. nanotechnology. Role had no influence. Specialists consensually viewed that nanotechnology represents opportunity, but depending on scientific background they did not agree to the same extent that nanotechnology also constitutes a risk. Participants with a physics and chemistry background tended to represent nanotechnologies predominantly in terms of opportunities and not in terms of inherent risks or impacts. In contrast, toxicologists, life and social scientists appeared to explicitly incorporate both benefits and risks in their representation of this new technology. Environmental scientists were a more diverse group, divided between the two patterns of representation.  相似文献

In this paper, we examine the long-run social mobility experience in England. We present evidence for surprisingly constant levels of social mobility over the period 1550–1749, despite huge structural changes. Examining regional differences, we show that the North of England exhibited higher rates of social mobility than the South. We link this to the hypothesis that historically high levels of social mobility can lead to a culture of non-acceptance of redistribution and welfare provision. Taking advantage of the fact that welfare provision was determined at the local level at the time, we are able to compare social mobility rates and welfare spending within a single country. Consistent with the hypothesis, we find evidence for historically higher levels of social mobility as well as lower welfare spending and less acceptance of redistribution in the North.  相似文献

Prior studies on attitudes towards brand extensions focus mainly on the effects of the perceived fit between the brand extension and the extension category. This exploratory paper contributes by describing two studies of how the following four extension category characteristics affect consumers' attitudes towards brand extensions: (1) the awareness set size; (2) the perceived similarity among existing brands; (3) the perceived category familiarity; and (4) overall category attitudes. Results from two studies suggest that consumers evaluate brand extensions more favorably when the awareness set size is small or when their attitude towards the extension category is favorable. Consequently, brand managers must analyze the extension category carefully when developing brand extensions.  相似文献

Immigrant street vendors in Chicago have fought for decades without success to change the restrictive and punitive city ordinance governing their work. The failure of the immigrant street vendors stands in marked contrast to the successful efforts of gourmet food truck entrepreneurs, who within only two years convinced the Chicago City Council to pass an ordinance permitting their work. The differential regulation of street vending reveals how local politicians use the rhetoric of the ‘creative’ city to justify building a city that appeals to young urban professionals, while simultaneously marginalizing the possibilities of working‐class immigrants to shape the city to their desires. This article aims to add to the literature on the politics of the creative class by demonstrating how discourses of creativity and entrepreneurialism get mobilized by competing interests, and how racial‐ethnic attitudes become integral to these discourses. The contrasting experiences of the vendors force us to ask: Why is the creativity of food truck entrepreneurs valued over the creativity of street vendors when, according to Richard Florida, creative class cities are supposed to be tolerant and immigrant‐friendly? Whose ‘creativity’ gets to be part of the ‘creative’ city? I draw on interviews with street vendors and a discourse analysis of media coverage of vending debates.  相似文献

Nonlinear relationships are common in economic theory, and such relationships are also frequently tested empirically. We argue that the usual test of nonlinear relationships is flawed and derive the appropriate test for a U‐shaped relationship. Our test gives the exact necessary and sufficient conditions for the test of a U shape in finite samples in a large class of models.  相似文献
