Cooperative Medium Access Control in Wireless Networks: The Two-Hop Case
2009
Cooperative communication has been recently proposed as a powerful means to improve network performance in wireless networks. However, most existing work focuses solely on one-hop source-destination cooperation. In this paper, we propose a novel cooperative MAC mechanism that is specially designed for two-hop cooperation communications where the source node and the destination node cannot hear each other directly. In this case, cooperative communication is operated in a two-hop manner and transmit-diversity is achieved by the reception of the same data packet forwarded through multiple relays towards a single destination. The proposed scheme employs an efficient relay selection algorithm to…
Control and Trust in Local School Governance
2014
External school inspection and state supervision represent key instruments in many European countries for improving the quality of education. Although some countries, such as England, France, and the Netherlands, have a long tradition of school inspectorates, other countries such as Sweden only recently reintroduced a school inspection system (Johansson O, Holmgren M, Nihlfors E, Moos L, Skedsmo G, Paulsen JM, Risku M, Local Decisions under Central Watch – a new Nordic quality assurance system. In: Moos L (ed) Transnational influences on values and practices in Nordic educational leadership – is there a Nordic model? Springer, Dordrecht, 2013). In Denmark, the relationship between the state…
INNOVATION AS A KEY FACTOR IN THE INTERNATIONAL COMPETITIVENESS OF THE EUROPEAN UNION
2013
There is international scientific consensus that economic progress will be driven by innovation, namely the invention and application of new technologies. Research and Development (R&D) is one category of spending that develops and drives these new technologies. From the perspective of competiveness, private sector firms are prone to focus their R&D on “applied” projects and many government-sponsored technological advances have been instrumental in driving economic growth and rising living standards. According to the published literature, it is expected that countries engaging in R&D activities have a comparative advantage in export of products, and countries with the “largest” R&D expendit…
The United Nations and the European Union
2019
The European Union (EU) and the United Nations (UN) are expressions of a rules-based global order. The EU has enshrined support to the UN in its security strategies, and its priorities indicate an engagement in a wide range of UN programs and activities to maintain the rules-based order and adapt it to face internal and external challenges. The EU and its member states are the largest contributors to the UN budget. Following the adoption of the Lisbon treaty, the EU has increased its representation at the UN, gaining enhanced observer status in the General Assembly. However, because of the intergovernmental nature of the forum, only its member states have the right to vote. This has led sch…
Adaptation of a German Multidimensional Networking Scale into English
2011
Networking refers to building and maintaining personal contacts in order to obtain resources that, in turn, enhance one’s career success and work performance. This study reports the translation and adaptation of a multifaceted German networking scale ( Wolff & Moser, 2006 ) into English and focuses on the equivalence of the two language versions. Going beyond the often used translation-backtranslation method, we used a parallel translation-backtranslation method in combination with two expert committees to arrive at the English scale version, aiming to obtain at least structural equivalence. We utilize a bilingual sample (N = 76) as well as monolingual samples from the US (N = 174) and…
CARACTERÍSTICAS MOTIVACIONALES DE PREESCOLARES CON BAJO RENDIMIENTO MATEMÁTICO
2016
El presente trabajo pretende profundizar en la motivación hacia el aprendizaje y el estilo atribucional de preescolares con bajo rendimiento matemático en relación a dos grupos de referencia: rendimiento medio y riesgo de Trastorno Específico de Aprendizaje con Dificultad Matemática (TEAP-DM). Participaron en el estudio 209 preescolares categorizados en función de su nivel de rendimiento aritmético mediante una prueba estandarizada. Se evaluaron los constructos de competencia-motivación, atención-persistencia y actitud hacia el aprendizaje, relacionadas con la motivación hacia el aprendizaje, y de internalidad, estabilidad y globalidad del estilo atribucional. Los resultados mostraron difer…
Planning for an environment-friendly car
2000
During the process of developing a new product, consciously or unconsciously, a number of decisions are made that affect the environment, thus making a company responsible not only for the technical performance but also for the “environmental performance” of a product. This research paper broadly speaks about this development process and lists the various tools available to the modern decision maker for balancing the ecological, economical and technological aspects of production. The focus of this paper is on the environmental issues in the automobile industry and environmental impacts presently associated with the automobile life cycle. The paper reviews existing tools and opportunities fo…
Progress in analysis of residual antibacterials in food
2007
Abstract Residual antibacterials in food constitute a risk to human health. Although epidemiological data on the real magnitude of their adverse effects are very scarce, they indicate that food could be an important avenue for evolution and dissemination of antibiotic-resistant bacteria. Analysis of these residues plays a key role in ensuring food safety, to the point that the European Union has not only established maximum residue limits but also requirements concerning the performance of analytical methods and the interpretation of the results. These specifications have had a great influence on protocols and techniques applied. In this review, we discuss the progress of rapid screening me…
The effect of hotel chain affiliation on economic performance: The moderating role of tourist districts
2020
Abstract This paper offers a pioneering analysis of the impact that integration in different types of hotel chains has on firm performance, and the moderating effect of the tourist destination in this relationship. Studies in the literature examine both size and location independently, without reconciling the apparently contradictory trends of globalization and conservation of the local base. The aim of the research is to analyze the comparative effects on tourism firms’ performance of belonging to different types of hotel chains while maintaining the advantages of location in a tourist destination. Based on a study of 292 Spanish hotels, the authors test the proposed hypotheses using hiera…
Joint Audit: Issues and Challenges for Researchers and Policy-Makers
2013
International audience; The publication of the European Commission Green Paper, ‘Audit Policy: Lessons from the Crisis’ in October 2010, has stirred up a lively debate on the role of joint audits. This literature review identifies and evaluates, for the benefit of future research and regulators, existing evidence about joint audits. We find limited empirical support to suggest that joint audits lead to increased audit quality, but some empirical support to suggest that joint audits lead to additional costs. Overall, this paper indicates that joint audit should be seen as a mechanism that is embedded in a broader institutional context and not be considered in isolation from other factors tha…
