Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa
2016
The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…
Electronic noses and tongues to assess food authenticity and adulteration
2016
Abstract Background There is a growing concern for the problem of food authenticity assessment (and hence the detection of food adulteration), since it cheats the consumer and can pose serious risk to health in some instances. Unfortunately, food safety/integrity incidents occur with worrying regularity, and therefore there is clearly a need for the development of new analytical techniques. Scope and approach In this review, after briefly commenting the principles behind the design of electronic noses and electronic tongues, the most relevant contributions of these sensor systems in food adulteration control and authenticity assessment over the past ten years are discussed. It is also remar…
How to Distribute a Cake before Cutting It into Pieces
2000
This article analyses social networks by looking at the standard making processes. As a framework for analysis, actor network theory is chosen. Standards are of particular interest for actor network theory for they provide mechanisms to align interests of multiple social groups organized in networks that have a joint incentive in working with the standards and /or associated technologies. These social groups include scientific communities, government institutions and social movements (industrial groups, companies, and consumers) that are interested in regulating and innovating with new technologies. Standards provide the mechanisms to inscribe subsequent behaviors that are expected to becom…
The Effect of Advanced Traveller Information Systems (ATIS) on public transport demand and its uncertainty
2009
Advanced Traveller Information Systems (ATISs) include a broad range of advanced computer and communication technologies. These systems are designed to provide transit riders pre-trip and real-time information, to make better informed decisions regarding their mode of travel, planned routes and travel times. ATISs include in-vehicle displays, terminal or wayside based information centres, information by phone or mobile and internet. In this article, a Stated Preference survey has been carried out in order to know the preferences of public transport’s customers related to different ATISs and their willingness to pay in Palermo. An ordered probit demand model has been calibrated to determine …
2017
Social media has become an important tool for sport organisations to interact with fans. In particular for sports that have smaller marketing budgets and that do not receive mainstream media coverage on a daily basis, social media platforms provide unique communication and marketing opportunities to overcome such challenges. This study investigates the motives of fans to communicate on the Facebook page of the International Table Tennis Federation (ITTF). It is the first study that focuses on the use of social media in the context of an international sport federation. Knowledge about the gratifications sought by fans while interacting on social media is important for organisations to develo…
Use and acceptance of new technology by older people. Findings of the international MOBILATE survey: ‘Enhancing mobility in later life’
2005
Technology has become part of today’s life. It constitutes a fundamental aspect of the environment also for older people who are not familiar with most of the new technologies. Is their use of technology based on certain abilities and is this related with such factors as income, lack of alternatives, past performance, or availability of equipment? Methods The MOBILATE 2000 database of a survey conducted in 5 European countries was aimed at the enhancement of out-of-home mobility of older people. The project offers data describing the use and acceptance of new technologies. Insight can be gained into the characteristics of users and non-users of more or less common technologies like ATM, tic…
E-negotiator based on buyer's surfing pattern
2017
Everyone likes to get the best price, but best price cannot be provided to everyone. This paper proposes an algorithm to provide the best price to the most prospective buyer. E-Negotiation will be based on buyer's activity pattern and surfing behavior. Unlike existing e-negotiation models proposed for B2C, B2B and C2C Ecommerce applications, where the intervention of buyer is present, this paper proposes a system to e-negotiate by just observing buyer's surfing pattern, without depending on his input. Surfing patterns such as sites visited and products surfed will tell the buyer's intention on purchasing the product. The amount of discount for negotiation is generated using a Fuzzy Inferenc…
Hand-Held texting is less distracting than texting with the phone in a holder: anyway, don't do it
2015
We studied the effects of texting while driving and the effects of mobile phone position (hand-held, holder) on drivers' lane-keeping performance, experienced workload, and in-car glance durations in a motion-platform driving simulator with 24 participants. Overall, we found the known negative effects of texting on lane-keeping performance, workload, and visual attention on road, suggesting that texting on the road in any manner is not risk-free. As a novel finding, we found that hand-held texting led to fewer lane-keeping errors and shorter total glance times off road compared to texting with the phone in a holder. We suggest the explanation is that the drivers had considerably more experi…
Determinants and Stakeholders Influencing Children's Road Safety Education
2016
Road safety education is, widely, the best base and the greatest assurance of the future in terms of road safety prevention and promotion. Nowadays, RSE constitutes one of the main growing concerns in terms of complimentary education in many countries, taking into account, among other factors, the high rates of accidents that affect the health and welfare of childhood and adolescence. Furthermore, it is a necessity for the community health to create, train, encourage and lead positives attitudes for good road safety education. The general objective of this study was to describe the factors and stakeholders that have influence on the learning of road safety education and safe behaviors of ch…
