why have all western-owned digital firms failed in china?

a new study from cass business school examines the failures of western internet firms (wifs) in china and why this phenomenon is singularly prevalent in this region. "government censorship and control, plus cultural differences between china and the west are often cited as the main reasons for such failures," said professor feng li, the study's author. "but similar conditions existed in other countries such as indonesia, thailand and saudi arabia, that did not prevent western internet firms such as google from dominating 90 per cent of the search market in these regions."what is a western internet firm?by definition western internet firms (wifs), also known as digital firms, are organisations that from inception focus on digital services e...




unc scientists create better laboratory tools to study cancer's spread

chapel hill - cancer that has spread, or metastasized, from its original site to other tissues and organs in the body is a leading cause of cancer death. unfortunately, research focused on metastatic disease has been limited by a lack of experimental systems that mimic the way metastatic cancers grow in people. now, researchers at the university of north carolina lineberger comprehensive cancer center report they have developed a laboratory model for studying metastatic cancer by applying techniques used in tissue engineering, a field in which scientists make enhanced or replacement tissue or organs. researchers believe their method better reflects the environment in and around tumors that have metastasized.in the journal nature biomedica...




hippo pathway found essential to orchestrate the development of the heart

"the hippo pathway is known for its role as an inhibitor of adult heart regeneration," said corresponding author dr. james martin, professor of molecular physiology and biophysics and vivian l. s...




upswings in older-age cognitive ability may not be universal

a growing body of evidence indicates that rates of dementia may be declining, in part because older adults' cognitive abilities, such as learning and memory functions, are better than those of older adults in the past. but most data have come from almost entirely white cohorts living in high-income countries, calling into question the universality of the trend. now, a study of a majority-black cohort, led by a boston university school of public health (busph) researcher, finds no clear upward trend in cognitive abilities among older adults. published in a special supplement to the journal of gerontology aiming to broaden the understanding of dementia trends in the united states, the study found trends in cognitive performance differ...

telling job seekers how many other people have applied could boost diversity

medford/somerville, mass. (april 23, 2018)--telling job applicants how many people applied for a job on linkedin - regardless of whether the number of applicants was high or low - increased the number of applications, a finding that could help companies that are seeking more diverse applicant pools, according to new research. the study, by tufts university economist laura gee, ph.d., and published this week in the journal management science, found that female candidates were especially more likely to apply for positions when information about the current number of applicants was advertised. gee suggests that this could help "ameliorate the gender occupation gap."linkedin ran the test over the course of 16 days in march 2012. gee later ana...




middle east energy subsidy reform updates 'patronage-based autocratic governance'

houston - (april 23, 2018) - a series of converging trends provided political cover for the reforms of long-standing energy subsidies launched by oil-exporting states in the middle east and north africa, according to a new paper by an expert in the center for energy studies at rice university's baker institute for public policy. these subsidies are thought to be an important source of legitimacy for autocratic regimes.the converging trends include fiscal stress from low world oil prices, escalating regional instability, international environmental pressure and untenable growth in domestic consumption of oil and gas, according to an article by jim krane, the wallace s. wilson fellow for energy studies at the baker institute, published on...




meditation and aerobic exercise helps women recover after sexual assault

women who are sexually assaulted and suffer from post-traumatic stress disorder (ptsd) can learn to decrease negative thoughts and enhance self-worth by a combination of meditation and aerobic exercise, according to a new rutgers university-new brunswick study.the research, published in frontiers in neuroscience, found that a combination of mental and physical, training with meditation and aerobic exercise done for one-hour twice a week over a six-week period significantly reduced post-traumatic and ruminative thoughts in women with a history of sexual violence. "despite the undeniable connection between sexual trauma and mental illness, few interventions are tailored for women who experience sexual violence," says tracey shors, distinguis...




the role of 'extra' dna in cancer evolution and therapy resistance

glioblastoma (gbm) is the most common and aggressive form of brain cancer. response to standard-of-care treatment is poor, with a two-year survival rate of only 15 percent. research is beginning to provide a better understanding of the processes underlying cell-to-cell differences within gbm tumors - a crucial finding because these differences contribute to therapy resistance.the ultimate goal is to identify what pathways can be targeted to block glioma progression. to this end, a multi-institutional team led by professor roel verhaak, ph.d., of the jackson laboratory (jax) and ana c. decarvalho, ph.d., assistant professor from henry ford health system's hermelin brain tumor center in detroit, mi, tracked genomic alterations detected in pati...

how do you get teens to stop cellphone use while driving? survey says, show them the money

philadelphia - teens who admit to texting while driving may be convinced to reduce risky cellphone use behind the wheel when presented with financial incentives such as auto-insurance apps that monitor driving behavior, according to a new survey conducted by researchers at the perelman school of medicine at the university of pennsylvania and children's hospital of philadelphia (chop). however, while more than 90 percent of teens surveyed said they were willing to give up sending or reading text messages, almost half indicated that they would want to retain some control over phone functions such as music and navigation. results of the survey are published in the journal traffic injury prevention."more than half of teens in the united state...

market failure, fake news and the first amendment

durham, n.c. -- the rise of social media and fake news challenge long-held assumptions about the first amendment and are undermining the functioning of the "the marketplace of ideas," a duke professor argues in a new article."there are a number of very specific ways in which the structure and operation of today's digital media ecosystem favors falsity over truth; and this shifting balance raises some troubling implications for how we think about the first amendment," says author philip napoli, professor at duke's sanford school of public policy. much of our thinking about the first amendment assumes that the answer to false speech is more speech, or counter-speech, and that the truth will triumph in the marketplace of ideas, he says. ...
