财经类高校GIS专业人才培养模式创新研究 总被引:1,自引:0,他引:1
我国教育部在1998年开始正式设置GIS专业,自此之后GIS专业得到了前所未有的高速发展。目前在众多开展GIS本科教育的院校中,主要集中在综合性院校、师范类院校和理工类院校,其他院校比如财经类院校较少。如在财经类高校开设GIS专业,由于所依托专业与主流GIS培养单位差异较大,因此人才培养模式就是一个关键问题。应结合财经类高校的特点和资源优势,以及市场需要,探讨财经类高校GIS专业的人才培养模式,并加以创新。 相似文献

集聚和扩散是创新驱动下高新区的核心功能,对于高新区可持续发展有着重要意义。首先,构建创新驱动、传导机制以及高新区功能三者关系的理论模型,由此提出研究假设;然后,运用结构方程模型并选取115个国家高新区企业作为样本进行实证研究。结果发现:①创新制度对高新区集聚功能的实现有正向影响,并且该影响通过创新型人才和金融共同发挥作用,即两者在实现路径上有完全中介效应;②创新环境正向影响高新区扩散功能的实现,且该影响主要通过创新型人才产生作用,即创新型人才在传导路径上有部分中介效应,而创新型金融的作用不明显。 相似文献

Drainage and loss of wetland sites is a major problem of the agricultural landscape, as it reduces the landscape’s ability to retain water, nutrients, matter, and minimize erosion. With this in mind, the issue of the ability of wet sites to retain radionuclides and contaminated water in the case of a radiation accident was studied. In 2013, field research examined the occurrence of wetland retention sites in the emergency planning zone (EPZ) of the Temelín nuclear power plant (NPP; Czech Republic). As data sources, wetland biotopes (European network Natura 2000) were considered; in addition, retention features were field mapped, i.e. landscape elements of a wetland nature not normally considered nationally significant for conservation. Within the emergency zone, 2854.7 ha of wetland biotopes were registered and 318.9 ha retention features mapped. Density of retention sites (in ha/km2) per cadastre (local administrative units) was used to represent their spatial distribution within the zone. For an assessment of possible revitalization measures, leading to an increase in the landscape’s retention ability, spatial changes in the area of retention sites between 2013 and the mid-19th century, a period before extensive drainage of landscape occurred and a simplification of its structure, were mapped. Historic land maps (The Imperial Obligatory Imprints of the Stable Cadastre) were used as a basis of information on the occurrence and area of fens and wet meadows (4771.5 ha).For spatial comparisons of drained and undrained landscape in the past and present, the density of retention sites per cadastre was calculated. In the mid-19th century, 80% of cadastres had a density of retention sites exceeded 5 ha/km2; in 2013 only 40% of cadastres achieved this. In the most part, drained areas of the zone belong to the central part (around the power plant), as well as the EPZ’s eastern and south-eastern regions. From the density maps of retention sites, as well as from the stable cadastre imprints, it is possible to identify areas and retention features suitable for wetland restoration, thus leading to an increase in the retention capacity of the landscape in terms of water and radionuclide retention. Suggestions as to how to restore and turn retention features into semi-natural wetlands, as well as integrating small wetlands into an agriculture landscape are outlined. 相似文献

The paper refers to the well-known Tsukui turnpike theorem on convergence of optimal growth trajectories in the closed dynamic Leontief model to the maximum balanced growth trajectory, called turnpike. In the original proof of this theorem, the assumption that the matrix B of capital coefficients is non-singular plays an essential role. For many reasons this assumption, very convenient for theoretical analysis, is not always satisfied in input-output systems built for empirical purposes. This paper fills the gap between theory and empirical studies, presenting a proof that convergence of optimal trajectories towards the turnpike is also a characteristic feature of the closed Leontief model in the case when matrix B is singular. The general idea of the proof is based on the approximation of a singular matrix B by an infinite sequence of non-singular matrices. 相似文献

In this article, we study the short- and long-run effects of trade openness in services on wage inequalities. The sample covers ten Organization for Economic Cooperation and Development (OECD) countries from 1980 to 2005. We find a differentiated impact of trade in goods compared to trade in services: while trade in goods has a short- and a long-run impact on inequalities, trade in services has only long-run effects. Moreover, we also find that international trade in services has a stronger impact on inequalities than international trade in goods, and this effect does not concern only inequalities between top incomes and low incomes but also between top incomes and median incomes. 相似文献

The behavioural perspective model of consumer choice (bpm) proposes three structural components of consumer situations from which consumers' verbal responses to consumption environments can be predicted. These are utilitarian reinforcement, informational reinforcement and behaviour setting scope. It is argued that pleasure, arousal and dominance, presented by Mehrabian and Russell as environmentally determined affective reactions, are respectively feasible verbal responses to these structural components. Consumers (N = 561) completed Mehrabian and Russell's measures of these affective reactions and of approach-avoidance for one of four ranges of verbally expressed consumption situations derived from the model. The results indicate that, for these theoretically grounded ranges of consumer situations, approach-avoidance is satisfactorily explained by pleasure, arousal and dominance. Further, mean differences in these affective variables between situations which, the bpm argues, show distinct patterns of reinforcement and behaviour setting scope are successfully predicted. 相似文献

The paper uses rolling sample tests to investigate time-varying calendar effects in the Chinese stock market, based on the GARCH (1, 1)-GED model. The Friday effect existed with low volatility at the early stage, but it seems to have disappeared since 1997. The positive Tuesday effect began to appear then. There is a small-firm January effect with high volatility. The turn-of-the month effect has also disappeared in the Chinese stock market since 1997. 相似文献
