The development of state farmland preservation policies has primarily relied upon results of the Census of Agriculture that is updated every 5 years by the USDA National Agriculture Statistics Service. Questions about the suitability of the Census of Agriculture center on the measures of total farmland and total cropland as reported by agricultural producers. The reliance on these variables fails to distinguish between conversion to developed uses and other fluctuations in the total availability of farmland. This inability to directly measure farmland conversion to developed uses has been shown to influence state level farmland preservation policies. The policies of Illinois and Indiana highlight the disparate approaches, with Illinois pursuing an intensive policy to protect farmland and Indiana choosing to not address farmland preservation at a state level. In order to assess the suitability of the different approaches to farmland preservation policy it is critical to evaluate the Census of Agriculture data used to justify the policies of Illinois and Indiana.  相似文献

We prove that the equilibria of a large interdependent-value, uniform-price auction model where bidders have arbitrary preferences for multiple units can be approximated by a nonatomic exchange economy. We show that the uniform-price auction is approximately efficient with a large number of participants and asymptotically aggregates idiosyncratic bidder information into the market price. More generally our analysis framework provides conditions justifying the use of nonatomic limit model approximations to analyze the large-market behavior of game-theoretic models. We demonstrate continuity requirements on the economic primitives sufficient for the equilibrium strategies of the two models to converge as the number of participants in the finite game approaches infinity.  相似文献

Using interviews conducted with 24 higher skilled working tourists employed as guest language instructors in the Republic of Korea, this paper explores how working tourists could secure an optimal leisure lifestyle in their host countries. Three key findings emerged. First, the respondents were seeking casual, touristic, amateur, hobby and volunteer leisure with their colleagues and with their host community members. But, the rewards and episodic aspects of their leisure, including formal and informal language development, suggested that it incorporated variations in project-based leisure as a core characteristic. Second, these respondents were taking part in guest, host and leisure speech communities that were each offering leisure choices. However, their leisure lifestyle was best when leisure, second language development and acculturation coincided in a leisure speech community. Third, that in a leisure speech community, respondents’ acculturation and friendships improved more so than in either guest or host speech communities. Also, that these respondents’ formal and informal second language learning within their leisure speech communities was essential for an optimal leisure lifestyle. The paper determines that leisure speech communities, occurring along a continuum of monetary, educational and interpersonal resources, could affect the linguistic mobility of higher skilled working tourists. It recommends that future research could examine if a sociolinguistics of leisure could assist in exploring and mapping the leisure lifestyles appearing among mobile populations in a globalising world.  相似文献

Burning bluegrass seed stubble is an important production practice that, among other benefits, increases production and stand life of this perennial crop. Despite economic forecasts that higher production costs from the 1996 state ban on seed stubble burning would reduce Washington production by up to 30%, output in the years 1998–2005 was nearly two-thirds higher than in any previous eight-year period. This study seeks to explain why that paradoxical behavior occurred. This study puts forward and systematically tests several hypotheses. The only hypothesis with any support, innovation offsets, is examined by an assessment of contemporaneous innovations and by corroborative statistical evidence.  相似文献

In this paper we use agency theory to present a process of the dichotomization of the Israeli workforce into two structures, each representing distinct organizational cultures. The first structure is the private sector, led by the high-tech industry; a model where the principal has strong control over the activities of the agent. The second is the public sector, an opposing model in which the principal has virtually no control over the activities of the agents and as a result, the effectiveness within this sector deteriorates. We argue that such conflicting systems cannot exist side by side without affecting each other and we suggest a role for human resource management (HRM) in future developments. Within the public sector it is the responsibility of the principal, the Israeli government, to gain more control over the agent and employ professional HRM systems for this purpose.  相似文献

This article considers processes of urban development within the context of mega‐event preparations in Rio de Janeiro. We begin with a brief overview of these development processes, highlighting their connections to political and economic change in recent years. Proponents of these mega‐event‐led initiatives argue that Rio is undergoing a period of inclusive growth and integration: a perspective we call here a ‘post‐Third‐World city' narrative of urban renewal. Critics, however, contend that urban officials are harnessing mega‐events (e.g. the 2014 World Cup and the 2016 Olympic Games) to push forward a neoliberal agenda of socially unjust policies benefiting the interests of capital and marginalizing the city's poor and especially its favelas (i.e. the ‘city‐of‐exception' thesis). In this article we explore the insights of these two perspectives and consider why they have grown popular in recent years. Though we side generally with the city‐of‐exception thesis, we argue that important geographic and historical particularities must also be accounted for. Without carefully situating analytical perspectives empirically—in particular, cases in which theoretical models are drawn from European and North American contexts—urban researchers risk concealing more than they reveal in analyses of rapidly developing countries like Brazil.  相似文献

This paper examines the impact of fiscal policies on both the size and educational levels of immigrants in destination countries. We find that whether or not a country’s policies are attracting highly educated immigrants goes beyond the issue of the “welfare state”. Immigrants are making important distinctions between the different benefits provided by a receiving country’s government. Health and education spending are found to have a positive impact on the education levels of immigrants while the reverse is true for unemployment and retirement benefits. Welfare programs are found to be insignificant once other government programs/taxes and other factors are taken into account. These results imply that countries should be less concerned about whether they are a “big government” with regards to attracting immigrants, and more concerned with what types of benefits they offer.  相似文献
