Diversification of old-age care services for older people: Trade-offs between coverage, diversification and targeting in European countries.
2011
Information on public services for older people is often limited to institutional care and Home Help/ Home Care, be it for individuals in surveys, statistics for a specific country or for international comparisons. Yet, these two major services in many countries are supplemented — or substituted — by other, minor services. The latter include services such as transportation services, meals-on-wheels, alarm systems, and day care. In this study the authors use various data sources to provide information on all or most of these types of support for Denmark, Norway, Sweden, Germany, England, Spain, and Israel, concluding with a closer scrutiny of Swedish service profiles. When all types of suppo…
Reciprocal Effects: Toward a Theory of Mass Media Effects on Decision Makers
2007
The article presents a framework for the analysis of reciprocal effects of mass media—in this case, their impact on subjects of media reports, especially on decision makers in areas of politics and business. It outlines a feedback model with three sets of variables referring to (1) media coverage and media as institutions, (2) awareness and processing of information, and (3) observable effects on subjects and others.The article presents several theories that explain effects on decision makers and illustrate the relevance of this approach with empirical data from a broad range of quantitative studies. In the final section, theoretical and methodological problems of such an approach are discu…
Vegetation and soil – related parameters for computing solar radiation exchanges within green roofs: Are the available values adequate for an easy mo…
2016
Several studies analyze the thermal performance of vegetated roofs, presenting either mathematical models or experimental quantifications of heat transfer process through them, also showing the effect of vegetation and soil parameters on the thermal and energy performance of this type of roofing system. However, presently the level of availability of these parameters, has not been enough considered. This work intends to investigate this underestimated issue of the green roofs’ thermal modeling, through the consideration of the availability of parameters pertinent to the shortwave radiation exchange, which are adopted by models based on leaf area index (LAI) and on the fractional vegetation …
Towards online bearing fault detection using envelope analysis of vibration signal and decision tree classification algorithm
2017
Online bearing fault detection is an important method for monitoring the health status of bearings in critical machines. This work proposes a classification algorithm, which can be extended towards an online bearing fault detection. The objective is to detect and classify the bearing faults in early stages. The overall design aspects of the online bearing fault detection and classification system are discussed. The proposed method is validated using experimental data, and a high accuracy of the fault classification was observed. Therefore, the proposed method can be applied for an online early fault detection and classification system.
The German Expellee Organizations: Unity, Division, and Function
2016
In the early twenty-first century, the German expellee organizations (Vertriebenenverbände) are typically portrayed as a united entity, at least in the wider public realm. The dominance of the umbrella group Bund der Vertriebenen (BdV) tends to foster the perception that the German expellee lobby is a homogeneous and cohesive bloc, focused on promoting shared political goals. This has been evident, for instance, in the media coverage of the prolonged controversy about the proposed establishment of a Center Against Expulsions in Berlin, in which the BdV’s statements have generally been taken to represent the expellee movement as a whole.1 But how correct is that interpretation, particularly …
A Geometrical Simple Approach for Power Silicon Devices Fault Detection and Fault-Tolerant Operation of a Voltage Source Inverter
2012
Fault-tolerant converters have been widely investigated for years and nowadays an extensive technical literature on this field exists. This paper presents a novel fault detection algorithm based on a simple geometrical approach. In the algorithm analysis both the case of faults in single device and the lose of an entire inverter leg have been considered. False positive detections are avoided by considering a proper number of current samples. The proposed fault detection algorithm is characterized by simplicity, low computational and implementation effort with a consequent enough fast execution, easy control integration with the possibility to use it both in hardware in the loop systems and …
Design, Building up and First Results of Three Monitored Green Coverings Over a University Department Building
2015
Abstract A viable solution to reducing the buildings’ energy demand is the implementation of green coverings that have been demonstrated to improve the envelope performance, especially in summer season. Anyway, to apply computer models analyzing the energy performance of buildings equipped with such components, the knowledge of specific parameters is needed. Among these, the fractional vegetation coverage and leaf area index are of great importance. By means of an experimental facility, first results of the evaluation of these foliage-related parameters for five types of vegetation are presented.
Distributed and proximity-constrained C-means for discrete coverage control
2018
In this paper we present a novel distributed coverage control framework for a network of mobile agents, in charge of covering a finite set of points of interest (PoI), such as people in danger, geographically dispersed equipment or environmental landmarks. The proposed algorithm is inspired by C-Means, an unsupervised learning algorithm originally proposed for non-exclusive clustering and for identification of cluster centroids from a set of observations. To cope with the agents' limited sensing range and avoid infeasible coverage solutions, traditional C-Means needs to be enhanced with proximity constraints, ensuring that each agent takes into account only neighboring PoIs. The proposed co…
The Impact of Financial Times Deutschland News on Stock Prices – Post Announcement Drifts and Inattention of Investors
2013
Within this paper, we analyze the impact of Financial Times Deutschland (FTD) news on stock prices and trading volumes. Based on a sample of all news on German DAX, MDAX and SDAX companies published within the news section of the FTD between 2006 and 2010, our results show that articles that contain positive (negative) information are associated with significantly positive (negative) abnormal returns and abnormal trading volumes around their publication. Furthermore, our results show an initial underreaction to these articles and a subsequent post publication drift. Based on the inattention hypothesis, we show that high-attention news (proxied by abnormal trading volume) almost instantaneou…
The international debt problem: An analysis of the Brady plan
1989
Recently the American Treasury Secretary, Nicholas Brady, launched a new initiative in which he proposed reducing the developing countries’ bank debt. What are the elements of the plan, and which countries would benefit? What problems does it entail? Can it bring about a decisive improvement in the international debt situation of the developing countries? The following two articles attempt to answer these questions.
