BUFFALO, N.Y. -- When managers issue a forecast of their firm's earnings, they do not always take into account prior forecasting errors, according to research in the current issue of the Journal of Business Finance & Accounting.
Weihong Xu, assistant professor of accounting in the University at Buffalo School of Management, analyzed more than 11,000 firm-quarter observations. She found that managers often underestimate the implications of their past forecasting errors when forecasting earnings.
A research team of the University of Granada (Spain) has confirmed a higher presence of the parasite Anisakis spp in anchovies of the Atlantic South East coast and the Mediterranean North West coast, and they insist on freezing or cooking fish before consuming it.
The drug Sprycel, approved for use by the U.S. Food and Drug Administration in patients with chronic myeloid leukemia, significantly inhibited the growth and invasiveness of ovarian cancer cells and also promoted their death, a study by researchers with UCLA's Jonsson Comprehensive Cancer Center found.
The drug, when paired with a chemotherapy regimen, was even more effective in fighting ovarian cancer in cell lines in which signaling of the Src family kinases, associated with the deadly disease, is activated.
More than 1 in 5 child deaths in low income countries are due to pneumonia. This death rate could be reduced if all affected children received effective pneumonia treatment (known as "standard case management"), which includes antibiotics and oxygen therapy. The government of Malawi recently introduced a national program for delivering standard case management for pneumonia to children.
Human movement is a key factor of dengue virus inflow in Rio de Janeiro, according to results from researchers based at the Oswaldo Cruz Foundation (Fiocruz) in Brazil. The results, based on data from a severe epidemic in 2007-2008, contribute to new understanding on the dynamics of dengue fever in the second largest city in Brazil. Details are published November 10 in the open-access journal PLoS Neglected Tropical Diseases.
The females of the recently discovered Osedax marine worms feast on submerged bones via a complex relationship with symbiotic bacteria, and they are turning out to be far more diverse and widespread than scientists expected. Californian researchers investigating the genetic history of Osedax worms have found that up to twelve further distinct evolutionary lineages exist beyond the five species already described. The new findings about these beautiful sea creatures with unusual sexual and digestive habits are published today in the online open access journal BMC Biology.
The alcohol industry's sponsorship of sport should be banned and replaced with a dedicated alcohol tax modelled on those employed by some countries for tobacco, say scientists.
Writing in the latest issue of the international journal Addiction, the authors have called on governments to outlaw the practice, citing their highly publicised 2008 study that showed alcohol-industry sponsorship of elite and community sport was associated with hazardous drinking among sport participants.
A new study, published in the November 17, 2009, issue of the Journal of the American College of Cardiology, adds to a growing body of research seeking to evaluate and understand possible sex differences associated with antiplatelet therapies. This study—the first to look at the impact of clopidogrel, one of the most frequently prescribed drugs to prevent and treat heart disease, in women—found it to be effective in reducing cardiovascular (CV) events in both men and women with no statistically significant sex differences in terms of expected clinical benefit or increased harm.
Aside from aging itself, obesity appears to be the most powerful predictor of left atrial enlargement (LAE), upping one's risk of atrial fibrillation (the most common type of arrhythmia), stroke and death, according to findings published in the November 17, 2009, issue of the Journal of the American College of Cardiology.
COLLEGE STATION – A recently devised method of imaging the chemical communication and warfare between microorganisms could lead to new antibiotics, antifungal, antiviral and anti-cancer drugs, said a Texas AgriLife Research scientist.
Overall survival (OS) may be a reasonable primary endpoint when the median survival postprogession (SSP) is less than 6 months, but it is too high a hurdle when SPP is longer than 12 months, according to a new study published online November 9 in the Journal of the National Cancer Institute.
This study was undertaken to examine whether progression-free survival (PFS) or OS is the most appropriate endpoint in clinical trials of metastatic cancer, and to determine if it is reasonable to expect that treatment benefit in PFS carries over to OS.
Human papillomavirus (HPV) DNA testing with cytology triage is more sensitive than conventional cytology screening for detecting cervical lesions, according to a new study published online November 9 in the Journal of the National Cancer Institute. Cytology triage in HPV-positive women can improve specificity.
HPV DNA testing has shown higher sensitivity than conventional cytology screening for detecting cervical lesions, but it is uncertain whether the higher sensitivity is dependent on the age of the woman being screened.
After one year, a low-calorie, low-fat diet appears more beneficial to dieters' mood than a low-carbohydrate plan with the same number of calories, according to a report in the November 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
One in four emergency department patients in 2006 waited longer to be evaluated by a clinician than recommended at triage, an increase from one in five in 1997, according to a report in the November 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Cumulative exposure to five common infection-causing pathogens may be associated with an increased risk of stroke, according to a report posted online today that will appear in the January 2010 print issue of Archives of Neurology, one of the JAMA/Archives journals.
