Abstract

A long, historical cooperation exists between sport and the media. The media can lift up the profile of a sport, and sport provides a marketable topic/product to talk about. Rules have been changed and playing conditions adapted to add to the glamor and spectacle of sport, thus making sport more marketable, enhancing media coverage and making it more appealing for the viewer. In the history of handball, rule changes have been introduced for the same purpose. However, changing the rules has a great effect on the team’s performance, and thus on the coaches’ work as well. There is no doubt that among the rule modifications introduced by the International Handball Federation (IHF) in 2016, substituting the goalkeeper for another court player during an attack without wearing a special shirt has had the greatest impact on the game in recent times. The main aim of the study was to carry out empirical research in order to analyze the recent rule modifications by the IHF, particularly when substituting the goalkeeper for an extra court player during an attack. The 2017 World Championship in France provided an ideal opportunity to collate data in order to explore how often and effectively teams used this rule change at the latest world event. In addition, we have also sought out the opinions of elite coaches concerning the state of current rules in handball and what they would change in order to make this sport discipline more marketable for the media and for spectators. The results show that teams substituted their goalkeeper for an extra court player when in numerical inferiority on average twice as much as when in numerical superiority and on average twice as often when losing as when winning. Surprisingly, the teams’ average scoring effectiveness was a little bit higher than when they played in numerical superiority or with an evenly reduced number of players. In addition, the outcome of focus group interviews shows that most coaches think that measuring the attacking time, introducing the third referee into the game, and having better judgment concerning the fast start-off is necessary for the betterment of the game.

Abstract

Lice (Phthiraptera) chew characteristic holes on the remiges and rectrices of Barn swallows (Hirundo rustica). The number of these holes correlate positively with the intensity of louse infestation, hence hole counts are useful to quantify lousiness. Several papers showed that lice affect both life expectancy and reproductive success of hosts. In male Barn swallows, the length of the outermost tail feathers act as a sexual signal. Females prefer long-tailed males, which have significantly fewer feather holes. In this study we sampled breeding and migrating Barn swallows and compared their louse burden, and the relationship between tail length and the number of feather holes. We found significant negative correlation between feather holes and tail length in breeding males; however, we found non-significant correlation in migrating males. We suggest that attractive males have more physical interactions (e.g. extra-pair copulation) during the breeding season, than less attractive males, hence they are more exposed to louse transmission, and therefore the difference in the infestation declines towards the end of the breeding season. However, given that migrating swallow groups include colonial and solitary breeding birds, it cannot be excluded that a potentially different louse distribution on solitary breeding birds may contribute to the results.

Abstract

The purpose of this research is to examine the economic freedom (EF) along with its macroeconomic determinants impact on Foreign Direct Investment (FDI) inflow in South Asia, East Asia, Latin America, Middle East, and North Africa, Northern Europe, Southern Europe, Western Europe, Eastern Europe and Sub Saharan Africa. We use Heritage Foundation economic freedom index data over the period of 1999 to 2018 and employ the stepwise multi regression on variables of business freedom, government spending, tax burden, government integrity, property rights, investment freedom, trade freedom and monetary freedom. The results show that EF has a significant positive impact in South Asia, Latin America, East Asia, North Europe and West Europe. However, for the Middle East and North Africa, East European and South European economies EF has an insignificant influence on FDI inflow.

Abstract

Jordan which is located in the heart of the world contains hundreds of historical and archaeological locations that have a supreme potential in enticing visitors. The impact of clime is important on many aspects of life such as the development of tourism and human health, tourists always wanted to choose the most convenient time and place that have appropriate weather circumstances. The goal of this study is to specify the preferable months (time) for tourism in Jordan regions. Neural network has been utilized to analyze several parameters of meteorologist (raining, temperature, speed of wind, moisture, sun radiation) by analyzing and specify tourism climatic index (TCI) and equiponderate it with THI index. The outcomes of this study shows that the finest time of the year to entice tourists is “ April” which is categorized as to be “extraordinary” for visitors. TCI outcomes indicates that conditions are not convenient for tourism from July to August because of high temperature.

Abstract

Giant cell arteritis is a systemic inflammatory vasculitis, typically involving the superficial temporal arteries, but with possible ischemic and hemorrhagic cerebrovascular complications.

The case is reported of a patient with a clinical picture of giant cell arteritis, who had multiple occupational exposures to various infectious agents.

His initial favourable progress was followed by an atypical outcome. Despite immunosuppressive treatment, he developed fatal subarachnoid and intracerebral haemorrhages, possibly due to rupture of a microaneurysm of the posterior cerebral artery.

Abstract

In health care databases, there are tireless and antagonistic interests between data mining research and privacy preservation, the more you try to hide sensitive private information, the less valuable it is for analysis. In this paper, we give an outlook on data anonymization problems by case studies. We give a summary on the state-of-the-art health care data anonymization issues including legal environment and expectations, the most common attacking strategies on privacy, and the proposed metrics for evaluating usefulness and privacy preservation for anonymization. Finally, we summarize the strength and the shortcomings of different approaches and techniques from the literature based on these evaluations.
