(Press-News.org) In some countries, a region that can lay claim to being the birthplace of a country's political leader is likely to get preferential treatment – bias that shines out when the intensity of night lights is compared with that in other regions.
This new approach to pinpointing regional favouritism has been developed by researchers from Monash University and the University of St Gallen. Using information on the birthplaces of political leaders in 126 countries, and satellite data on night-time light intensity from 38,427 subnational regions from 1992-2009, they established a strong relationship between light intensity and regional GDP.
Dr Paul Raschky from the Monash Centre for Development Economics and Sustainability said previous research had confirmed the connection between economic activity and light generated at night. But relating night-time light intensity to information about the birthplaces of politicians gave new insights into what determines regional favouritism.
"Our results suggest that being the leader's birthplace increases night-time light intensity and regional GDP by around four and one per cent respectively," Dr Raschky said.
Thelarge sample of countries in the study included both democracies and autocracies.
Zaire's former dictator Mobutu Sese Seko provided an extreme example of the phenomenon, Dr Raschky said. Mobutu had bank accounts and properties all over the world, but spent his money most lavishly in his remote hometown of Gbadolite.
"Mobutu built a huge palace complex costing millions of dollars, luxury guesthouses, an airport capable of handling Concords, and had the country's best supply of water, electricity and medical services," Dr Raschky said.
"The satellite imagery over the Gbadolite region clearly showed the rise of Mobutu, starting off with very little night-time light intensity through to extremely high levels during his reign, then easing off once he was no longer in power."
Similar effects were noted elsewhere, with any benefits gained by favoured regions unlikely to be sustained beyond a change in government. Inevitably, such favouritism was most common in countries with weak political institutions and poorly educated citizens.
"Sound political institutions and education are socially desirable and help keep political leaders accountable," Dr Raschky said.
"We demonstrate their importance in constraining regional favouritism. The enforcement of term limits also seems to be a crucial aspect."
The researchers also looked at the effect of regional favouritism on the distribution of foreign aid and oil rents.
"Our findings suggest that donor agencies need to be very cautious when supporting countries with authoritarian leaders because such leaders mainly use foreign aid to the benefit of themselves, their family and clan members, and others living in their stronghold," Dr Raschky said.
He hopes his new approach will aid future research on regional favouritism and the political economy of regional development.
The research has been published in Quarterly Journal of Economics.

Adolescents from southern Europe are less fit and more obese than central-northern European peers
2014-07-09
Adolescents in southern Europe are less fit in terms of cardiorespiratory capacity, strength and speed-agility than their central-northern European peers. Moreover, southern adolescents are more obese and present higher levels of total and abdominal fat than those from the centre-north of Europe.
These are some of the remarkable results from an ambitious study conducted by scientists from the University of Granada Department of Medical Physiology in collaboration with 25 other European research groups. The study compared the level of physical fitness of adolescents living ...
Cinnamon may be used to halt the progression of Parkinson's disease
2014-07-09
(CHICAGO) – Neurological scientists at Rush University Medical Center have found that using cinnamon, a common food spice and flavoring material, can reverse the biomechanical, cellular and anatomical changes that occur in the brains of mice with Parkinson's disease (PD). The results of the study were recently published in the June 20 issue of the Journal of Neuroimmune Pharmacology.
"Cinnamon has been used widely as a spice throughout the world for centuries," said Kalipada Pahan, PhD, study lead researcher and the Floyd A. Davis professor of neurology at Rush. "This ...
Rockefeller scientists first to reconstitute the DNA 'replication fork'
2014-07-09
When a cell divides, it must first make a copy of its DNA, a fundamental step in the life cycle of cells that occurs billions of times a day in the human body. While scientists have had an idea of the molecular tools that cells use to replicate DNA—the enzymes that unzip the double-stranded DNA and create "daughter" copies—they did not have a clear picture of how the process works.
Now, researchers at Rockefeller University have built the first model system to decipher what goes on at the "replication fork"—the point where DNA is split down the middle in order to create ...
Discovery of a new means to erase pain
2014-07-09
Québec City, July 9, 2014 – A study published in the scientific journal Nature Neuroscience by Yves De Koninck and Robert Bonin, two researchers at Université Laval, reveals that it is possible to relieve pain hypersensitivity using a new method that involves rekindling pain so that it can subsequently be erased. This discovery could lead to novel means to alleviate chronic pain.
The researchers from the Faculty of Medicine at Université Laval and Institut universitaire en santé mentale de Québec (IUSMQ) were inspired by previous work on memory conducted some fifteen ...
Nearly 50 percent of grade 12 students in Ontario report texting while driving
2014-07-09
EMBARGOED - July 9, 2014, 3:01 a.m. ET (Toronto) – An ongoing survey of Ontario students in grades 7 to 12 conducted for Canada's Centre for Addiction and Mental Health (CAMH) reveals a number of significant behavioural trends, including an alarming number of young people who are texting while driving.
According to the 2013 Ontario Student Drug Use and Health Survey (OSDUHS) Mental Health and Well-Being Report, over one-third of licensed Ontario students in grades 10 to12 – an estimated 108,000 adolescent drivers – report texting while driving at least once in the past ...
Study finds kidney donation safe for healthy older adults
2014-07-09
Older kidney donors enjoy similar longevity and cardiovascular health as other healthy mature individuals, according to a new study published in the American Journal of Transplantation. The findings may provide some reassurance to older individuals considering donation and the transplant professionals caring for them.
Over the past two decades, live kidney donation by individuals aged 55 years and older has become more common. Given the links between older age, kidney disease, and heart disease, the removal of a kidney could make older donors vulnerable to premature death ...
For corals adapting to climate change, it's survival of the fattest -- and most flexible
2014-07-09
COLUMBUS, Ohio—The future health of the world's coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat—and to be flexible about the type of algae it cooperates with.
In the first study of its kind, scientists at The Ohio State University discovered that corals—tiny reef-forming animals that live symbiotically with algae—are better able to recover from yearly bouts of heat stress, called "bleaching," when they keep large energy reserves—mostly as fat—socked away in their cells.
"We found that some coral ...
Mode of delivery following a perineal tear and recurrence rate in subsequent pregnancies
2014-07-09
There is an increased risk of severe perineal tearing during childbirth in women who had such a tear in a previous delivery, suggests a new study published today (9 July) in BJOG: An International Journal of Obstetrics and Gynaecology (BJOG).
This study, investigates among women who have had a third or fourth degree perineal tear, the mode of delivery in subsequent pregnancies and the recurrence of severe perineal tears.
Most women tear to some extent during childbirth and in some women the tear may be more extensive. A third degree tear extends downwards from the ...
Fun or exercise?
2014-07-09
Think of your next exercise workout as a "fun run" or as a well-deserved break, and you'll eat less afterward. Think of it as exercise or as a workout and you'll later eat more dessert and snacks to reward yourself.
These new findings from the Cornell Food and Brand Lab study involved two studies where adults were led on a 2 km walk around a small lake and were either told it was going to be an exercise walk or a scenic walk. In the first study, 56 adults completed their walk and were then given lunch. Those who believed they had been on an exercise walk served and ...
New plant species from the heart of Texas
2014-07-09
SALT LAKE CITY, July 9, 2014 – Collectors found the first two specimens of the prickly plant in 1974 and 1990 in west Texas. Then, for two decades, the 14-inch-tall plant was identified wrongly as one species, then another and then a third.
Now – after a long search turned up a "pathetic, wilted" third specimen – a University of Utah botanist and her colleagues identified the spiny plant as a new, possibly endangered species and named it "from the heart" in Latin because it was found in Valentine, Texas, population 134 in 2010.
Most new plant species are found in the ...
