(Press-News.org) In order to arrive at this result the researchers calculated the price with a model that measures the number of medals according to government expenditure in sport, along with other variables. "This model allows accurate measurement of how much extra expense is necessary to win each medal," the UC3M professors Juan de Dios Tena and Ramón J. Flores explained, who carried out this study within the Sports Economics Research Group, headed by professor David Forrest, of the University of Salford (England) and which also includes Ismael Sanz from the Universidad Rey Juan Carlos and Jaime Álvarez from Universidad Complutense of Madrid. "We have estimated the relation between this expenditure and Olympic success once relevant economic, political, and demographic variables are taken into account, such as the size of the country," Tena pointed out. This study was presented at the workshop "The Economic of the Olympic Games" at Groningen in July of 2008, entitled "Can governments buy Olympic medals?" and at present is in the revision process for publication in a research journal.
In the area of Sport Economics these researchers use econometric models (usually regression models) to analyze sports phenomena in which there are economic determinants. The basic general idea is that there are many possible causes for a phenomenon. "A regression model offers an estimate of the individual effect of each of these causes, once the others are controlled for", explained professor Flores, which allows him to draw rigorous conclusions from the statistics models that can thus determine the concrete influence of an element within the context of sport..
The dilemma of sacking a coach
In the case of football teams, for example, this research group has analyzed the figure of the technical trainer and discovered that the effect of sacking a coach during the season is more negative than positive when this situation happens more than once. "Changing coaches reduces by half the number of points obtained in the next eight games for a unit," he remarked. Based on the results obtained during several seasons by the clubs in the Argentinean league, the econometric model that they have developed shows an inverse relation between the number of sackings and team results. In a nutshell, the more sackings, the worse results in the middle term. "Similar studies carried out in European leagues, where the number of sackings is lower, does not show such an effect, suggesting that abusing the number of sackings can generate negative consequences within this context," concluded these UC3M Statistics Department professors.
Another subject related to the researchers' work is the effect that the 1995 Bosman Law has had on competitivity in the most important football leagues. Before that law, in national competitions there was a very strict limitation governing the number of foreign players which could be signed on by each team, resulting in the available top foreign players usually going to the bigger clubs. With the new legislation eliminating this limitation, the number of players available greatly increased, so that the low and mid level clubs were also able to become stronger and increase their level as well as in tournament play. "In order to measure this increase we use measurements known in the literature, such as the percentage of points over the total obtained by the top two, four or ten teams in the league, as well as taking into account other factors which influence in the modification of the market, such as getting into Champions League and its resulting benefits," they noted The conclusion after the Bosman Law came into effect is that the ratio of points of the top two teams decreased by 2 percent and by 4 percent for the top eight teams. .
This type of data and research can serve to orient and aid in the decision-making process. In addition, the answers obtained can be extrapolated to wider contexts. "Our intention is to apply them profusely, and to collaborate in resolving issues which generate debate in society, and which produce interesting conclusions. These matters are rarely studied with the rigor that they deserve," asserted these professors from the UC3M Colmenarejo campus, who have the impression that in this area, work is presented as an "analysis" which scarcely goes beyond mere opinion. "Due to the media nature of anything related to sport, there are often statistical studies of low quality or which are carried out directly by fans and obtained by unscientific methods from samples which are not at all reliable."

More than allergies: Histamine may be a possible drug target for multiple sclerosis
2011-02-01
If you think histamines are your nemesis during allergy season, here's something that might change your perspective. New research published in the Journal of Leukocyte Biology (http://www.jleukbio.org) shows that histamine could be an important molecule to developing new treatments for multiple sclerosis (MS). In the study, the scientists analyzed the role of histamine in an animal model of multiple sclerosis and found that histamine plays a critical role in preventing MS or lessening its effects.

Revealing the wiring that allows us to adapt to the unexpected
2011-02-01
Milan, Italy, 31 January 2010 – Wouldn't life be easy if everything happened as we anticipated? In reality, our brains are able to adapt to the unexpected using an inbuilt network that makes predictions about the world and monitors how those predictions turn out. An area at the front of the brain, called the orbitofrontal cortex, plays a central role and studies have shown that patients with damage to this area confuse memories with reality and continue to anticipate events that are no longer likely to happen. The brain's ability to react adaptively, becomes crucial for ...
Scientists climb Mt. Everest to explain how hearts adapt and recover from low oxygen
2011-02-01
From the highest mountaintop comes a new research report in the FASEB Journal (http://www.fasebj.org) that gets to the bottom of what happens to the hearts of people when exposed to low-levels of oxygen, such as those on Mount Everest or in the intensive care unit of a hospital. In the study, researchers monitored subjects who spent time at the Mount Everest Base Camp and found that the low-level oxygen conditions at the base came caused changes in heart function resembling what is seen in conditions that severely restrict the amount of oxygen to the heart, such as cystic ...
Researchers bust bat rabies stereotype
2011-02-01
Bats tend to have a bad reputation. They sleep all day, party at night, and are commonly thought to be riddled with rabies. A study by University of Calgary researchers has confirmed that bats are not as disease-ridden as the stigma suggests.
"The notion that bats have high rates of rabies is not true," says Brandon Klug, a graduate student at the University of Calgary and the lead author of a paper published in the Journal of Wildlife Diseases.
"Those of us that work with bats have always known the rates are low; and now we have evidence that bats aren't disease-ridden ...
The science of bike-sharing
2011-02-01
Tel Aviv — The new environmentally-friendly concept of municipal "bike-sharing" is taking over European cities like Paris, and American cities like New York are also looking into the idea. It allows a subscriber to "borrow" a bike from one of hundreds of locations in the city, use it, and return it to another location at the end of the journey. It's good for commuters and for running short errands.
While the idea is gaining speed and subscribers at the 400 locations around the world where it has been implemented, there have been growing pains — partly because the projects ...
Plankton inspires creation of stealth armor for slow-release microscopic drug vehicles
2011-02-01
The ability of some forms of plankton and bacteria to build an extra natural layer of nanoparticle-like armour has inspired chemists at the University of Warwick to devise a startlingly simple way to give drug bearing polymer vesicles (microscopic polymer based sacs of liquid) their own armoured protection.
The Warwick researchers have been able to decorate these hollow structures with a variety of nanoparticles opening a new strategy in the design of vehicles for drug release, for example by giving the vesicle "stealth" capabilities which can avoid the body's defences ...
The changing roles of 2 hemispheres in stroke recovery
2011-02-01
Milan, Italy, 31 January 2010 – Most people who survive a stroke recover some degree of their motor, sensory and cognitive functions over the following months and years. This recovery is commonly believed to reflect a reorganisation of the central nervous system that occurs after brain damage. Now a new study, published in the February 2011 issue of Elsevier's Cortex, sheds further light on the recovery process through its effect on language skills.
For almost all right-handed people and for about 60% of left-handers, damage to the left side of the brain causes a condition ...
Young rats given polyphenols show less endothelial function deterioration with aging
2011-02-01
The endothelium is the inner lining of our blood vessels and normal functions of endothelial cells include enabling coagulation, platelet adhesion and immune function. Endothelial dysfunction is associated with reduced anticoagulant properties and the inability of arteries and arterioles to dilate fully.
The gradual decrease in endothelial function over time is a key factor in the development of diseases associated with ageing, especially cardiovascular disease (CVD). Many epidemiologic studies suggest protection against CVD from moderate intake of alcoholic beverages, ...
Recalled ICD leads fail in women, youths most often
2011-02-01
The recalled Sprint Fidelis implantable cardioverter-defibrillator (ICD) leads (Medtronic) failed more often in younger patients, women, and individuals with hereditary heart disease, according to a multicenter study published online Jan. 17 in Circulation. The researchers found that lead failure was not associated with death or serious injuries.
However, about half of the patients whose leads fractured experienced painful inappropriate shocks, according to lead author Robert G. Hauser, MD, of the Minneapolis Heart Institute® at Abbott Northwestern Hospital. In a previous ...
Scientists find key protein that suppresses prostate cancer growth in the laboratory
2011-02-01
Cancer researchers have discovered an important protein, produced naturally inside cells, that appears to suppress the growth of prostate cancer cells in the laboratory. The findings, published tomorrow in the journal Cancer Research, offer promising leads for research towards new treatments.
Prostate cancer is the most common cancer among men in the UK, with 37,500 men diagnosed with the disease every year. Many prostate cancers are slow growing, but in some cases the cancer is aggressive and spreads to other parts of the body, such as the bone. These cases are much ...
