ABSTRACT

European Union (EU) institutions have cultivated narratives of European integration for a long time. For its 2013–2014 ‘A New Narrative for Europe’ project, however, the European Commission for the first time explicitly used the ‘narrative’ label. Drawing on non-participant observation, semi-structured interviews and qualitative discourse analysis, this article contrasts the drafting process and the resulting declaration’s narrative structure and content with its discussion by citizens in a web-based consultation. The analysis shows that participating citizens forcefully demanded a bottom-up debate and advocated pluralistic perspectives. In these circumstances, elite-driven attempts at strengthening European identity and EU legitimacy are likely to be ineffective.  相似文献

A non‐parametric kernel estimator of the spectral density of stationary random closed sets is studied. Conditions are derived under which this estimator is asymptotically unbiased and mean‐square consistent. For the planar Boolean model with isotropic compact and convex grains, an averaged version of the kernel estimator is compared with the theoretical spectral density.  相似文献

Summary Forecasts for the number of students in Germany are conducted by the Kultusministerkonferenz. They use a transition model which does not allow for prediction intervals and therefore lack a measure of uncertainty of the forecast. Since the uncertainty is high for such forecasts, this lack is of importance. In this paper, structural ratios, relating the number of university students to the population of the same age, are analyzed and forescasted using ARIMA-models with outliers. Multiplying these ratios with official population forecasts for Germany provides the future number of students, additionally giving prediction intervals. This number will increase from 1.94 million in 2002 to 2.35 million in 2015. The uncertainty of the forecast is high; the forecast interval in 2015 will range between 1.72 and 2.98 million at a 95% confidence level. Supported by the German Research Foundation (DFG). We are grateful to an anonymous referee for some helpful comments.  相似文献

Vocation-coaching — Coaching in phases of personal reorientationA model for a coaching-method, the “Vocation-coaching” is presented, which was used successfully in the last two years. The main aspects of the model, namely discovering — strengthen — transfer, are described. The coaching-techniques which are used within the vocation-coaching are compared to the techniques of the conventional coaching. The target group of the vocation-coaching are individuals at turning points in their lives, especially at turning points in their professions. The needs of these persons are described and compared to the potential use of the method of the vocation-coaching.  相似文献

Investments in dedicated and flexible capacity have traditionally been based on demand forecasts obtained under the assumption of a predetermined product price. However, the impact on revenue of poor capacity and flexibility decisions can be mitigated by appropriately changing prices. While investment decisions need to be made years before demand is realized, pricing decisions can easily be postponed until product launch, when more accurate demand information is available. We study the effect of this price decision delay on the optimal investments on dedicated and flexible capacity. Computational experiments show that considering price postponement at the planning stage leads to a large reduction in capacity investments, especially in the more expensive flexible capacity, and a significant increase in profits. Its impact depends on demand correlation, elasticity and diversion, ratio of fixed to variable capacity costs, and uncertainty remaining at the times the pricing and production decisions are made.  相似文献

Regarding the effect of product variety on purchase probability, there exist findings which demonstrate a positive effect of variety for small assortments and a negative effect of variety for large assortments. Despite these results, little evidence exists about the causal mechanism of this effect. We conduct a field study among German consumer electronics customers to investigate the previously proposed constructs of anticipated product utility, anticipated regret and evaluation costs. The results suggest that anticipated regret and evaluation costs play a powerful role in explaining the negative link between variety and purchase probability for high variety assortments. Anticipated product utility on the other hand serves to explain part of the positive causality for low variety assortments. The results obtained give rise to recommendations for the planning of assortments.

This paper analyses poverty and inequality in South Africa based on data from a comprehensive multi-purpose household survey undertaken in 1993 to provide baseline statistics on poverty and its determinants to the new government. The paper shows that South Africa has among the highest levels of income inequality in the world and compares poorly in most social indicators to countries with similar income levels. Much of the poverty in the country is a direct result of apartheid policies that denied equal access to education, employment, services, and resources to the black population of the country. As a result, poverty has a very strong racial dimension with poverty concentrated among the African population. In addition, poverty is much higher in rural areas, and particularly high in the former homelands. Poverty among female-headed households and among children is also higher than average. Moreover, poverty is closely related to poor education and lack of employment. The poor suffer from lack of access to education, quality health care, basic infrastructure, transport, are heavily indebted, have little access to productive resources, and are heavily dependent on remittances and social transfers, particularly social pensions and disability grants. The paper uses an income-based definition of poverty for most of the analysis. In addition, it develops a broad-based index of deprivation including income, employment, wealth, access to services, health, education, and perceptions of satisfaction as its components. While on average the two indicators correspond fairly closely, the income poverty measure misses a considerable number of people who are severely deprived in many of the non-income measures of well-being. This group of severely deprived not identified by the income poverty measure consists predominantly of Africans living in rural areas, concentrated particularly in the province of KwaZulu/Natal.  相似文献

Physicians are losing their historic franchise as sole and primary providers of medical care. In addition to eroding moral and scientific authority, physicians are also losing income and status. It is no wonder that physicians are retrenching--confused and angry about the increasing marginalization of their profession and about society's changing expectations. Physicians are caught in a transition zone between the world that was and the one that will soon be. This is destabilizing and causes great anxiety. Rather than being buffeted by changing social and cultural definitions of health care, physicians must become proactively involved in the future of their profession. Physicians can only do this by offering a better mental model of health, medicine, and the community. This cannot be a defensive retreat from engagement. Rather, it must be an imaginative vision, vigorously set forth--a vision that will enlist the support of all constituencies involved in the effort to improve the health and well-being of all members of our society. The physician executive needs to work with physicians to orchestrate this effort to create a new vision of health in the 21st century.  相似文献

While young researchers in the field of social sciences are taught how to identify potential target groups for their interviews as well as to identify the appropriate survey and interpretation techniques, the actual access to the field poses a difficult problem (there is great potential for frustration when some requests for interviews are rejected). Usually, the specific motives for such a non-response stay unresolved. Access is even harder when the target group includes representatives of elite groups (e. g. top managers) - a group that is characterised by intense time pressure and typical behaviour patterns (both are factors which increase the difficulty of access to that group). This article aims to give a detailed outline of this problem from contribution and status related perspectives and to provide solutions for young researchers to enable them experiencing the field entry process (as far as putting a foot in the manager’s office) as challenging, but controllable.  相似文献
