From cars to bikes – the feasibility and effect of using e-bikes, longtail bikes and traditional bikes for transportation among parents of children a…
2017
Abstract Background The present study aims to increase bicycling and level of physical activity (PA), and thereby promote health in parents of toddlers, by giving access to different bicycle types. There is a need for greater understanding of e-bikes and their role in the transportation network, and further effects on PA levels and health. Moreover, longtail bikes could meet certain practical needs not fulfilled by e-bikes or traditional bikes, hence increased knowledge regarding their feasibility should be obtained. No previous studies have investigated whether providing an e-bike or a longtail bike over an extended period in a sample of parents of toddlers influence objectively assessed a…
The MOBI-Kids Study Protocol: Challenges in Assessing Childhood and Adolescent Exposure to Electromagnetic Fields from Wireless Telecommunication Tec…
2014
The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF). MOBI-Kids, a multinational case–control study, investigates the potential effects of childhood and adolescent exposure to EMF from mobile communications technologies on brain tumor risk in 14 countries. The study, which aims to include approximately 1,000 brain tumor cases aged 10–24 years and two individually matched controls for each case, follows a common protocol and builds upon the methodological experience of the INTERPHONE study. The design and conduct of a study on EMF exposure an…
The Internet and SMEs in Sub-Saharan African Countries
2011
The Internet is a global network of interconnected computers using multiple Internet protocols (IP). Increasingly, it is being used to enhance business operation by both small and medium-sized enterprises (SMEs) and large organizations around the world (Bunker and MacGregor, 2002; Turban, Lee, King, & Chung, Lee, J., King, D. & Chung 2004). One reason is that the Internet, when used to facilitate e-commerce and e-business, offers several benefits for the adopting organizations (Walczuch, den Braven, & Lundgren, 2000; Turban, et al, 2004). Such benefits include the following: 1) reducing distance barrier, 2) the development of new products and services, 3) opening direct links be…
Unwanted effects of European Union environmental policy to promote a post-carbon industry. The case of energy in the European ceramic tile sector
2016
Global warming combined with low carbon transition plans is threatening the future of high energy consumption industry sectors in the European Union (EU). The need to respond to environmental challenges is demonstrated by support for international level energy policies and legal requirements, such as the Kyoto Protocol which the EU supports, and increased EU-level environmental legislation and energy policies. The effect of these initiatives is gradually transforming industrial activities in the EU. However, since not all countries have adopted these policies, evaluation of their net effect needs to take account also of side-effects such as delocalization of industry activity and the legal …
CO2 Prices, Energy and Weather
2007
One of the main objectives of the European Union Emission Trading Scheme is the establishment of a market price level for allowances that show to European CO 2 emitting installations the environmental impact of their polluting activities. The aim of this paper is to focus on the daily price changes during 2005 in an attempt to examine the underlying rationality of pricing behaviour. Specifically, we study the effect of those weather and non-weather variables that academic and market agents consider as the major determinants of the of CO 2 price levels. The results show that the energy sources are the principal factors in the determination of CO 2 price levels, and that only extreme temperat…
Climate Change and Global Justice: New Problem, Old Paradigm?
2014
In this paper, we focus on the conceptualization of climate change as an issue of global justice. While we do not deny that climate change raises fundamental and dramatic issues of justice among peoples as well as generations, our claim is that the language of global justice can obscure the fact that problems provoked by climate change lack some characteristic features of problems of global justice, while possessing others that are not characteristic of such problems. We begin by describing briefly how we got to where we are, climatically speaking; we go on to show why it is plausible to think of climate change as provoking problems of global justice; point out four respects in which this d…
Implantación de recursos didácticos digitales en asignaturas de Organización de Empresas
2013
El objetivo de este artículo es presentar el protocolo de implantación de diversas herramientas didácticas, así como el nivel de satisfacción de los estudiantes que las utilizan. Los resultados muestran, primero, que no es posible crear un único protocolo aplicable a todos los recursos, debido a las diferencias en los objetivos didácticos existentes. Segundo, la valoración que los estudiantes hacen de la utilización de los recursos es muy positiva, aunque existen algunas diferencias entre las distintas herramientas. Estos resultados permiten mejorar los recursos y adecuarlos al perfil de los estudiantes para que éstos puedan sacar el mayor provecho posible.
Frailty and emergency surgery in the elderly: protocol of a prospective, multicenter study in Italy for evaluating perioperative outcome (The FRAILES…
2018
Improvements in living conditions and progress in medical management have resulted in better quality of life and longer life expectancy. Therefore, the number of older people undergoing surgery is increasing. Frailty is often described as a syndrome in aged patients where there is augmented vulnerability due to progressive loss of functional reserves. Studies suggest that frailty predisposes elderly to worsening outcome after surgery. Since emergency surgery is associated with higher mortality rates, it is paramount to have an accurate stratification of surgical risk in such patients. The aim of our study is to characterize the clinicopathological findings, management, and short-term outcom…
A software tool to acquire, synchronise and playback multimedia data: an application in kinesiology
2000
Assessing the physical condition of the human body frequently requires evaluating different tests performed by different devices. This information has to be analysed simultaneously to derive conclusions, and so a temporal relationship must be established between the data sources. In this paper, synchronisation of the sources of information is achieved by synchronising the clocks of computers connected in a Local Area Network. A clock synchronisation protocol is used and a global time is stamped in each information data flow. During analysis, the time-stamp is used to playback the data in a synchronised way. The proposed system is valid for any medical application in which data synchronisati…
Evaluating the Performance of Real Time Videoconferencing in Ad Hoc Networks Through Emulation
2008
The validation of new video protocols and applications for mobile ad hoc networks in a real environment is an important task. In this work we present Castadiva, a test-bed architecture that allows validating software solutions for ad hoc networks using low-cost, off-the-shelf devices and open source software. We use this tool to test a videocall using the OLSR protocol in different scenarios, varying the number of hops between the caller and the receiver. The results obtained in this paper show that, for an ad hoc network with a large number of hops, the quality of videocalls suffers a significant degradation even in the absence of mobility.
