The purpose of this study is to evaluate the performance of the European airlines, using a balanced scorecard perspective. Within this scope, a hybrid multi-criteria approach was used by combining the Fuzzy DEMATEL, Fuzzy ANP, and MOORA methods. The results demonstrate that customer dimensions and profit per customer are the most significant key factors in the balanced scorecard perspective. Additionally, the airline companies with the largest profit (per employee) and highest number of passengers and flights (per employee) had the best scores in the multidimensional performance results. Furthermore, the airline companies with the highest profitability and efficiency are more successful than other companies. Therefore, we recommend European airlines to focus on these aspects in order to improve their performance. This study makes an important contribution to literature by helping to solve a significant problem in the market with the proposed methodology.  相似文献

We consider superhedging of contingent claims under ratio constraint. It has been widely recognized that the minimum cost of superhedging a contingent claim with certain portfolio constraints is equal to the price of a claim with appropriately modified payoff but without constraints. In terms of the backward stochastic differential equation (BSDE) and the variational inequality equation approach, we revisit this result and provide two counterexamples.  相似文献

Maintaining ecosystem continuity has become a central element in spatial planning policies. Several authors acknowledge the environmental, also known as landscape, fragmentation due to human action as one of the main causes which have negative effects on biodiversity. The phenomenon consists of the transformation of larger patches of habitat in smaller ones, or fragments, which tend to be more isolated than in the original condition. It is extremely evident in urban areas, including settlements and various transport and mobility infrastructures, whose main ecological effects include loss of habitat, increased mortality of plants, and isolation of animal and vegetal species. In this paper, we assess landscape fragmentation dynamics of six landscape units belonging to two European regions, i.e. Sardinia in Italy (from 2003 to 2008), and Andalusia in Spain (from 2005 to 2009). We developed on three indices: the Infrastructural Fragmentation Index (IFI), the Urban Fragmentation Index (UFI), and the Connectivity Index (CI). We found that coastal areas generally suffer from an higher pressure due to the demand of longer or faster transport infrastructures and new settlements and less fragmented areas tend to show the most relevant dynamics in a sort of convergent pattern. Even though landscape fragmentation and connectivity are intuitively complementary phenomena, in this paper we did not found any statistical evidence of this associative property.  相似文献

To better understand the share of the nonobserved economy (NOE) in the European Union, especially on the PIIGS, we estimate, through the multiple indicators multiple causes model, the path between 1980 and 2013. The model includes (i) the tax burden (disaggregated into direct and indirect taxes), a proxy of regulation burden, the unemployment rate and self-employment as causes of the NOE economy; (ii) the GDP and the labour force participation ratio as indicators of the NOE economy. In particular, the estimated weight of NOE as a percentage of official GDP was always higher in the PIIGS group.  相似文献

During the European financial crisis, the European Central Bank implemented a series of unconventional monetary policy measures. We argue that these programs lowered the bond yield spreads of Euro-area countries. This hypothesis is tested using pooled OLS estimations and two different datasets: monetary policy event dummies and the purchase volumes of the Securities Markets Programme (SMP). Overall, we find significantly negative effects on bond yield spreads for both datasets, leading us to accept the hypothesis. While the OMT reduces the spreads of both crisis and non-crisis countries, LTROs and the lowering of the deposit rate to 0 percent are mainly effective in non-crisis countries. The SMP lowers the spreads of crisis countries, but it has the opposite effect on non-crisis countries. This converse effect is explained by the risk that increasingly accumulates on the ECB’s balance sheet through the SMP and that way constitutes a fiscal risk for non-crisis countries. The results are confirmed by pooled OLS estimations that measure the effect of unconventional monetary policy on central government debt.  相似文献

Land management is inevitably linked to the regulation of activities of its proprietor or operator stipulated by legislation and documents of territorial planning. In Lithuania, as in many European countries, territorial planning is a key measure for the formation of landscape and the alteration of its elements. With the help of territorial planning documents, governing authorities has the opportunity to orderly regulate the layout of long-term stable elements of landscape and the sustainable territorial development. However, in comparison with other European Union (hereinafter – EU) countries, territorial planning system valid in Lithuania until January 1, 2014 is still “young” and having specific features with former countries of the Soviet bloc legal regulation. The system did not provided a consistent and sustainable territorial development mechanism: there was the lack of measures allowing to manage the development processes of residential areas and implementation of territorial planning documents (especially the municipal master plans) solutions for the creation of a harmonious functional spatial system. The aim of the present paper is to assess the regulation of legal relations of territorial planning in Lithuania and the EU member states. The assessment summarizes processes of the formation of a landscape during the territorial planning, introduces new opportunities to more accurately predict the results of the current process of landscape planning, and highlights legal and sustainable elements of territorial planning system optimization. As can be seen from the assessment carried out, one of the most important territorial planning objectives was and still remains the balance of mutual relations (hierarchy of plans) of territorial planning documents in shaping the cultural landscape to ensure the rational distribution of the land fund, combining a variety of activities as well as often different land users’ and public interests. Therefore, the implementation of the territorial planning reform of Lithuania capacitates for the transition to an integrated territorial planning, ensuring sustainable development.  相似文献

In recent decades the intensification of agricultural production in many European countries has been one of the key components of land-use change. The impact of agricultural intensification varies according to national and local contexts and a greater understanding of the drivers of intensification will help to mitigate against its negative impacts and harness potential benefits. This paper analyses changes in land use intensity in six case studies in Europe. A total of 437 landowners were interviewed and their responses were analysed in relation to changes in land use intensity and agricultural production between 2001 and 2011. In the case studies in Western and Eastern Europe we observed stabilisation during the last decade, and no clear tendency of increase or decrease of land use intensity. The use of fertilizers and pesticides seems to have decreased in our cases in Western Europe, which is contrary to trends in Eastern Europe. Agricultural production remained stable in almost all cases, except for an increase in Austria and Romania which may indicate that the farming efficiency has increased. A statistical analysis showed a division between study areas in Romania and Austria (increasing land use intensity) versus those in the Netherlands, Denmark and Greece (decreasing). In the Mediterranean cases we observe a process where agriculture is becoming increasingly marginalised, at the same time as changes in function with regard to urbanisation and recreational land uses have taken place. Logistic regression highlighted the importance of farm size and farmer type in understanding changes in land use intensity. The dominant pattern of stabilisation which has occurred over the past 10 years may also partly be a result of effective EU and national environmental and agricultural policies, which are increasingly concerned with improving environmental conditions in rural areas.  相似文献

Though most landscape ecologists have integrated scaling issues in their works, these issues are often disregarded in landscape perception and preference studies. Researchers base their studies on a predefined single scale to assess the landscape, and they pay little attention to the scale specificity of their analysis and recommendations. We reconsidered three landscape assessment studies from our research unit in light of scaling issues. In addition to the scale of the assessed landscape, researchers should address the scale of the landscape surrogate that is submitted for assessment, including the spatial references of the people surveyed and the target level of application of the results. Indeed, many of the landscape assessment methods mix different landscape notions and scales. Therefore, we recommend the cautious use of these assessments, the integration of qualitative insights in addition tithe scoring and paying attention to the perception scale, as defined by Fairclough (2006).  相似文献

Landscape assessment methods have traditionally valued the landscape through a panel of experts with little or no participation of the population. However, after the adoption of the European Landscape Convention (ELC), the perception and the participation of the population has played an increasingly important role in landscape evaluation and planning. In this regard, the goal of this paper is to develop a model able to evaluate and integrate both the objective and subjective landscape factors into a new concept: the Preservability. This model, as well as selecting and classifying the landscape attributes according to the bio-geographic features of the study area i.e., Ricote Valley (Region of Murcia, Spain), includes two online surveys: one to assess the populatiońs landscape preferences and the other to obtain the specific weight of each objective and subjective landscape factor from a panel of experts. These landscape factors were incorporated into a GIS. To obtain the best model, the Preservability was assessed from three different approaches: objective, objective-weighted and weighted. The final results demonstrate how the Preservability weighted method returns different thresholds appropriate to the landscape attributes, the population’s perceptual preference and the protected areas. The different thresholds allows for priority areas to be identified for protection, as well as the adoption of appropriate management and planning strategies according to the landscapes characteristics, current state and uniqueness.  相似文献

Landscapes are linked to human well-being in a multitude of ways, some of which are challenged by global market forces and traditional management approaches. In response to this situation there has been a rise in local initiatives to sustain the values of landscape. The aim of this paper is to provide a systematic analysis of the spectrum of these initiatives in Europe in terms of patterns of organisation, participants, resources, problems, and landscape values addressed. This review collects examples of integrated landscape initiatives from all over Europe through systematic internet key word searches and canvassing of European umbrella organisations; followed by an online survey of representatives from the identified initiatives (n = 71). Our results show that the most relevant characteristics of integrated landscape initiatives in Europe are: a holistic approach to landscape management (acting in multifunctional landscapes and combining different objectives), the involvement and coordination of different sectors and stakeholders at many levels, and the role as agents of awareness raising and learning hubs. Integrated landscape initiatives mainly depend on impulses of local civil society. Identified barriers to their work include a lack of funding and institutional support. Therefore, political and societal action is needed to increase their effectiveness.  相似文献
