Political correctness could affect holiday weight gain

Political correctness could affect holiday weight gain

But, there is one factor most people likely won't consider -- political correctness.

Research from Duke University's Fuqua School of Business suggests you could be choosing unhealthy options to serve your guests because you don't want to offend someone else.

Marketing doctoral student Peggy Liu and Fuqua marketing professor Gavan Fitzsimons led a team that conducted multiple experiments into how people choose between healthy and unhealthy food options when they are picking for both themselves and another person.

"We wanted to understand if food choices would change if they were picking a dish or snack for themselves and an average-sized person versus themselves and an overweight person," Liu said.

Their findings, "Matching Choices to Avoid Offending Stigmatized Group Members," are published in the November 2013 issue of the journal Organizational Behavior and Human Decision Processes.

In one of the studies, participants were asked to choose a snack option of either wheat crackers or chocolate chip cookies for themselves and a person they had just met. In some cases, the recently introduced woman appeared as her normal size (wearing a size 0-2). In other situations, the woman was wearing a body suit that appeared to increase her weight by nearly 65 pounds (making her closer to a size 16).

Researchers discovered most participants (almost 60 percent) would choose the same snack for themselves and the woman when she appeared overweight. When the woman appeared her normal size, participants only choose the same snack about 30 percent of the time. When picking for themselves and the overweight women, participants didn't overwhelmingly choose one particular snack over the other (about 30 percent chose cookies and about 30 percent selected wheat crackers).

"What the results show is that people pick the same snack to avoid offending someone they perceive as overweight. This means that people might pick unhealthier options for themselves and others during the holidays if they think not doing so could hurt someone's feelings," Fitzsimons said.

In similar, additional studies, participants told researchers they thought it would be offensive either to give an overweight person healthy food and then take unhealthy food for themselves or, conversely, to give an overweight person unhealthy food and then take healthy food for themselves.

"This suggests that if you are heading back to the buffet to cut a piece of pumpkin pie for your overweight uncle, you might also cut a larger piece than normal for yourself, so you don't hurt his feelings," Liu said.

The research has implications beyond the buffet line.

"As marketers increasingly recognize that the shopper is often not the consumer of products and we often make product choices for others in our lives, firms need to better factor in a consumers' desire to match consumption within the household to avoid offense," Fitzsimons said.

"Counter to common marketing wisdom, a single product that adequately meets the needs of multiple family members without offending any may dominate individual items that perfectly meet the needs of each family member but raise the risk of offense," "Liu said.

Expert assessment: Sea-level rise could exceed one meter in this century

Expert assessment: Sea-level rise could exceed one meter in this century

In contrast, for a scenario with strong emissions reductions, experts expect a sea-level rise of 40-60 centimeters by 2100 and 60-100 centimeters by 2300. The survey was conducted by a team of scientists from the USA and Germany.

"While the results for the scenario with climate mitigation suggest a good chance of limiting future sea-level rise to one meter, the high emissions scenario would threaten the survival of some coastal cities and low-lying islands," says Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research. "From a risk management perspective, projections of future sea-level rise are of major importance for coastal planning, and for weighing options of different levels of ambition in reducing greenhouse-gas emissions."

Projecting sea-level rise, however, comes with large uncertainties, since the physical processes causing the rise are complex. They include the expansion of ocean water as it warms, the melting of mountain glaciers and ice caps and of the two large ice sheets in Greenland and Antarctica, and the pumping of ground water for irrigation purposes. Different modeling approaches yield widely differing answers. The recently published IPCC report had to revise its projections upwards by about 60 percent compared to the previous report published in 2007, and other assessments of sea-level rise compiled by groups of scientists resulted in even higher projections. The observed sea-level rise as measured by satellites over the past two decades has exceeded earlier expectations.

Largest elicitation on sea-level rise ever: 90 key experts from 18 countries

"It this therefore useful to know what the larger community of sea-level experts thinks, and we make this transparent to the public," says lead author Benjamin Horton from the Institute of Marine and Coastal Sciences at Rutgers University in New Jersey. "We report the largest elicitation on future sea-level rise conducted from ninety objectively selected experts from 18 countries." The experts were identified from peer-reviewed literature published since 2007 using the publication database 'Web of Science' of Thomson Reuters, an online scientific indexing service, to make sure they are all active researchers in this area. 90 international experts, all of whom published at least six peer-reviewed papers on the topic of sea-level during the past 5 years, provided their probabilistic assessment.

The survey finds most experts expecting a higher rise than the latest IPCC projections of 28-98 centimeters by the year 2100. Two thirds (65%) of the respondents gave a higher value than the IPCC for the upper end of this range, confirming that IPCC reports tend to be conservative in their assessment.

The experts were also asked for a "high-end" estimate below which they expect sea-level to stay with 95 percent certainty until the year 2100. This high-end value is relevant for coastal planning. For unmitigated emissions, half of the experts (51%) gave 1.5 meters or more and a quarter (27%) 2 meters or more. The high-end value in the year 2300 was given as 4.0 meters or higher by the majority of experts (58%).

While we tend to look at projections with a focus on the relatively short period until 2100, sea-level rise will obviously not stop at that date. "Overall, the results for 2300 by the expert survey as well as the IPCC illustrate the risk that temperature increases from unmitigated emissions could commit coastal populations to a long-term, multi-meter sea-level rise," says Rahmstorf. "They do, however, illustrate also the potential for escaping such large sea-level rise through substantial reductions of emissions."

RF, Microwave Optoelectronics LED Engin adds zoom optics to lighting LEDs

RF, Microwave Optoelectronics LED Engin adds zoom optics to lighting LEDs

2013/11/22

LEDPR022-graphicLED Engin has combined Gaggione 8 to 45-degree zoom optics with its LZ4-Plus emitters to offer higher candela/lumen performance, beam quality and control.

The 4-die RGBW emitters for wash lamps and follow spots can be driven to 1.5A per die to produce higher output.

“Matched to the Gaggione lenses, this technology enables luminaire manufactures to design much smaller, lighter and more powerful products,” said the supplier.

Colour control is achieved via the ability to individually address each die, in conjunction with in-source color mixing. There is no need for separate colour filters.

Based on LED Engin’s proprietary LuxiGen platform, the LZ4 emitters, capped with flat glass primary lenses, are used with secondary optics, including zoom lenses and imaging optics.

The die are mounted close together to create a very small light source. This has two benefits: it maximizes in-source mixing to produce uniform color across the beam and it enables very narrow beam angles to be created. Precisely controlled narrow beam angles, down to 8 degrees or less, can only be produced when a very compact light source is employed.

College students more likely to be lawbreakers if spanked as children

College students more likely to be lawbreakers if spanked as children

Nov. 22, 2013 — No matter where they live in the world, university students who were spanked as children are more likely to engage in criminal behavior, according to new research by Murray Straus, co-director of University of New Hampshire Family Research Lab. Even young adults whose parents were generally loving and helpful as they were growing up showed higher rates of criminal behavior.


Share This:





Straus will present the research results, "Crime by University Students in 15 Nations: Links to Spanking and Positive Parenting at Age 10 by Father, Mother, And Both Parents," today at the annual meeting of the American Society of Criminology in Atlanta.

"The results show that spanking is associated with an increase in subsequent misbehavior, which is the opposite of what almost everyone believes. These results are consistent with a large number of high quality peer-reviewed studies," Straus said.

Straus looked at criminality trends of university students in 15 countries using nine measures of criminality. The measures are criminal beliefs, antisocial personality, father assaulted by child in previous year, mother assaulted by child in previous year, physical assault of partner in previous year, severe physical assault of partner in previous year, physically injured partner in previous year, attacked someone intending to seriously injure them, and stolen money from anyone, including family.

The 15 countries are Hong Kong, Taiwan, Belgium, Greece, Italy, Norway, Poland, Russia, Scotland, Slovenia, Spain, Switzerland, Israel, Canada, and the United States. Straus took into account the influence of such factors as parental education, misbehavior as a child, loving and positive approach to correcting misbehavior, student gender, student age, and nation. One of the most interesting findings was related to the effect of parents who took a loving and positive approach but who also spanked their children.

"So many parents and child psychologists believe that if spanking is done by loving and helpful parents, it has no harmful effect," Straus said. "This study and only one other study I know of that empirically investigated this belief found that it is not true. Spanking seems to be associated with an increased probability of subsequent child behavior problems regardless of culture and, regardless of whether it done by loving and helpful parents."

"Children need lots guidance and correction, but not by being physically attacked under the euphemism of 'spanking,' " Straus said.

Straus found that positive parenting decreased the probability of subsequent crime but mainly for nonfamily crime. And even though positive parenting was associated with less crime by students, the relation of spanking to crime remained for all nine aspects of crime.

"Most people will find these results hard to understand because parents spank to correct misbehavior and to teach the child to be law-abiding citizens," Straus said.

Straus also investigated the criminal behavior of university students who were spanked just by their fathers, just by their mothers, or by both parents. He found that university students who were spanked by both parents are associated with the greatest increase in criminality for eight of the nine criminality measures.

In most of the 15 nations, two-thirds of university students said they were hit when they were age 10, and among those who were hit, they said it typically was between once and twice a week. If university students were hit by only one parent, more often than not the mother was the parent carrying out the punishment.

Straus' findings are based on data from the International Parenting Study of 15 nations and 11,408 university students.

Widely considered the foremost researcher in his field, Straus is the co-director of the Family Research Laboratory and professor emeritus of sociology at UNH. He has studied spanking by large and representative samples of American parents since 1969. His newest book is "The Primordial Violence: Spanking Children, Psychological Development, Violence, and Crime" (Routledge, 2013). He also is the author of "Beating The Devil Out Of Them: Corporal Punishment In American Families And Its Effects On Children" (Transaction, 2006).

He has been president of three scientific societies including the National Council on Family Relations, and has been an advisor to the National Institutes of Health and the National Science Foundation. Much of his research on spanking can be downloaded from http://pubpages.unh.edu/~mas2.

Straus's research was supported, in part, by a grant from the National Institute of Mental Health.

Pre-industrial rise in greenhouse gases had natural and anthropogenic causes

Pre-industrial rise in greenhouse gases had natural and anthropogenic causes

A new study, which will be published Friday in the journal Science, suggests the increase in methane likely was caused by both.

Lead author Logan Mitchell, who coordinated the research as a doctoral student at Oregon State University, said the "early anthropogenic hypothesis," which spawned hundreds of scientific papers as well as books, cannot fully explain on its own the rising levels of atmospheric methane during the past 5,000 years, a time period known as the mid- to late-Holocene. That theory suggests that human activities such as rice agriculture were responsible for the increasing methane concentrations.

Opponents of that theory argue that human activities during that time did not produce significant amounts of methane and thus natural emissions were the dominant cause for the rise in atmospheric CH4.

"We think that both played a role," said Mitchell, who is now a post-doctoral researcher at the University of Utah. "The increase in methane emissions during the late Holocene came primarily from the tropics, with some contribution from the extratropical Northern Hemisphere.

"Neither modeled natural emissions alone, nor hypothesized anthropogenic emissions alone, are able to account for the full increase in methane concentrations," Mitchell added. "Combined, however, they could account for the full increase."

Scientists determine methane levels by examining ice cores from polar regions. Gas bubbles containing ancient air trapped within the ice can be analyzed and correlated with chronological data to determine methane levels on a multidecadal scale. Mitchell and his colleagues examined ice cores from the West Antarctic Ice Sheet Divide and the Greenland Ice Sheet Project and found differences between the two.

Ice cores from Greenland had higher methane levels than those from Antarctica because there are greater methane emissions in the Northern Hemisphere. The difference in methane levels between the hemispheres, called the Inter-Polar Difference, did not change appreciably over time.

"If the methane increase was solely natural or solely anthropogenic, it likely would have tilted the Inter-Polar Difference out of its pattern of relative stability over time," Mitchell said.

Since coming out of the ice age some 10,000 years ago summer solar insolation in the Northern Hemisphere has been decreasing as a result of the Earth's changing orbit, according to Edward Brook, a paleoclimatologist in Oregon State's College of Earth, Ocean, and Atmospheric Sciences and Mitchell's major professor. This decrease affects the strength of Asian summer monsoons, which produce vast wetlands and emit methane into the atmosphere.

Yet some 5,000 years ago, atmospheric methane began rising and had increased about 17 percent by the time the industrial revolution began around 1750.

"Theoretically, methane levels should have decreased with the loss of solar insolation in the Northern Hemisphere, or at least remained stable instead of increasing," said Brook, a co-author on the Science article. "They had been roughly on a parallel track for some 800,000 years."

Mitchell used previous models that hypothesized reasons for the methane increase - both natural and anthropogenic - and compared them to the newly garnered ice core data. None of them alone proved sufficient for explaining the greenhouse gas increase. When he developed his own model combining characteristics of both the natural and anthropogenic hypotheses, it agreed closely with the ice core data.

Other researchers have outlined some of the processes that may have contributed to changes in methane emissions. More than 90 percent of the population lived in the Northern Hemisphere, especially in the lower latitudes, and the development of rice agriculture and cattle domestication likely had an influence on methane emissions. On the natural side, changes in the Earth's orbit could have been responsible for increasing methane emissions from tropical wetlands.

"All of these things likely have played a role," Mitchell said, "but none was sufficient to do it alone."

The study was supported by the National Science Foundation's Office of Polar Programs, with additional support from the Oregon National Aeronautics and Space Administration (NASA) Space Grant Consortium.

Archaeologists discover largest, oldest wine cellar in Near East: 3,700 year-old store room held 2,000 liters of strong, sweet wine

Archaeologists discover largest, oldest wine cellar in Near East: 3,700 year-old store room held 2,000 liters of strong, sweet wine

Nov. 22, 2013 — Would you drink wine flavored with mint, honey and a dash of psychotropic resins? Ancient Canaanites did more than 3,000 years ago.

Archaeologists have unearthed what may be the oldest -- and largest -- ancient wine cellar in the Near East, containing forty jars, each of which would have held fifty liters of strong, sweet wine. The cellar was discovered in the ruined palace of a sprawling Canaanite city in northern Israel, called Tel Kabri. The site dates to about 1,700 B.C. and isn't far from many of Israel's modern-day wineries.

"This is a hugely significant discovery -- it's a wine cellar that, to our knowledge, is largely unmatched in age and size," says Eric Cline chair of the Department of Classical and Near Eastern Languages and Civilizations of at The George Washington University. Cline and Assaf Yasur-Landau, chair of the Department of Maritime Civilizations at the University of Haifa, co-directed the excavation. Andrew Koh, assistant professor of classical studies at Brandeis University, was an associate director.

The team's findings will be presented this Friday in Baltimore at the annual meeting of the American Schools of Oriental Research.

Koh, an archaeological scientist, analyzed the jar fragments using organic residue analysis. He found molecular traces of tartaric and syringic acid, both key components in wine, as well as compounds suggesting ingredients popular in ancient wine-making, including honey, mint, cinnamon bark, juniper berries and resins. The recipe is similar to medicinal wines used in ancient Egypt for two thousand years.

Koh also analyzed the proportions of each diagnostic compound and discovered remarkable consistency between jars.

"This wasn't moonshine that someone was brewing in their basement, eyeballing the measurements," Koh notes. "This wine's recipe was strictly followed in each and every jar."

Important guests drank this wine, notes Yasur-Landau.

"The wine cellar was located near a hall where banquets took place, a place where the Kabri elite and possibly foreign guests consumed goat meat and wine," he says.

At the end of the season, the team discovered two doors leading out of the wine cellar -- one to the south, and one to the west. Both probably lead to additional storage rooms. They'll have to wait until 2015 to find out for sure.

Business Qualcomm, Samsung add BeiDou to Glonass and GPS for more precise location tracking.

Business Qualcomm, Samsung add BeiDou to Glonass and GPS for more precise location tracking.

2013/11/22

Samsung Galaxy Note 3Samsung and Qualcomm are adding access to China’s BeiDou Satellite Navigation System to help improve location accuracy in GPS devices.

The Samsung Galaxy Note 3 (pictured) has a Qualcomm chip-set which accesses BeiDou. It is the first to use three constellations – the US GPS constellation, the Russian Glonass constellation and BeiDou.

BeiDou-enabled phones mean access to more satellites, which increases location accuracy. This ultimately improves customers’ pedestrian navigation, speeds local searches and enhances other location-based services.

Qualcomm’s mobile chipsets feature interoperability with existing constellations which use tri-band hardware integration to deliver improved location capabilities in an optimal way, with enhanced accuracy, and with no additional increase in power consumption.

In Qualcomm’s Snapdragon and Gobi chipsets, global positioning support is built into the modem and RF chips, enabling the location signals to be processed in the modem, instead of waking up the apps processor, thus saving power without sacrificing location accuracy.

Colossal new predatory dino terrorized early tyrannosaurs

Colossal new predatory dino terrorized early tyrannosaurs

Named after a cannibalistic man-eating monster from Ute tribal legend, Siats is a species of carcharodontosaur, a group of giant meat-eaters that includes some of the largest predatory dinosaurs ever discovered. The only other carcharodontosaur known from North America is Acrocanthosaurus, which roamed eastern North America more than 10 million years earlier. Siats is only the second carcharodontosaur ever discovered in North America; Acrocanthosaurus, discovered in 1950, was the first.

"It's been 63 years since a predator of this size has been named from North America," says Lindsay Zanno, a North Carolina State University paleontologist with a joint appointment at the North Carolina Museum of Natural Sciences, and lead author of a Nature Communications paper describing the find. "You can't imagine how thrilled we were to see the bones of this behemoth poking out of the hillside."

Zanno and colleague Peter Makovicky, from Chicago's Field Museum of Natural History, discovered the partial skeleton of the new predator in Utah's Cedar Mountain Formation in 2008. The species name acknowledges the Meeker family for its support of early career paleontologists at the Field Museum, including Zanno.

The recovered specimen belonged to an individual that would have been more than 30 feet long and weighed at least four tons. Despite its giant size, these bones are from a juvenile. Zanno and Makovicky theorize that an adult Siats might have reached the size of Acrocanthosaurus, meaning the two species vie for the second largest predator ever discovered in North America. Tyrannosaurus rex, which holds first place, came along 30 million years later and weighed in at more than twice that amount.

Although Siats and Acrocanthosaurus are both carcharodontosaurs, they belong to different sub-groups. Siats is a member of Neovenatoridae, a more slender-bodied group of carcharodontosaurs. Neovenatorids have been found in Europe, South America, China, Japan and Australia. However, this is the first time a neovenatorid has ever been found in North America.

Siats terrorized what is now Utah during the Late Cretaceous period (100 million years ago to 66 million years ago). It was previously unknown who the top meat-eater was in North America during this period. "Carcharodontosaurs reigned for much longer in North America than we expected," says Zanno. In fact, Siats fills a gap of more than 30 million years in the fossil record, during which time the top predator role changed hands from carcharodontosaurs in the Early Cretaceous to tyrannosaurs in the Late Cretaceous.

The lack of fossils left paleontologists unsure about when this change happened and if tyrannosaurs outcompeted carcharodontosaurs, or were simply able to assume apex predator roles following carcharodontosaur extinction. It is now clear that Siats' large size would have prevented smaller tyrannosaurs from taking their place atop the food chain.

"The huge size difference certainly suggests that tyrannosaurs were held in check by carcharodontosaurs, and only evolved into enormous apex predators after the carcharodontosaurs disappeared," says Makovicky. Zanno adds, "Contemporary tyrannosaurs would have been no more than a nuisance to Siats, like jackals at a lion kill. It wasn't until carcharodontosaurs bowed out that the stage could be set for the evolution of T. rex."

At the time Siats reigned, the landscape was lush, with abundant vegetation and water supporting a variety of plant-eating dinosaurs, turtles, crocodiles, and giant lungfish. Other predators inhabited this ecosystem, including early tyrannosaurs and several species of other feathered dinosaurs that have yet to be described by the team. "We have made more exciting discoveries including two new species of dinosaur," Makovicky says.

"Stay tuned," adds Zanno. "There are a lot more cool critters where Siats came from."

All fieldwork was conducted under permits through the Bureau of Land Management and funded by the Field Museum. Research was funded by North Carolina State University, North Carolina Museum of Natural Sciences and the Field Museum.

Business Intel changing, say senior management

Business Intel changing, say senior management

2013/11/22

Intel CEO brian krzanich

Intel CEO Brian Krzanich


Intel is changing said its top bosses at the new CEO’s first investor day.

Brian Krzanich, Intel CEO, said that Intel will be more responsive to customers’ needs which is being taken as a sign that they’ll fab chips for customers even if the chips compete with Intel’s proprietary products.

Intel president Renee James says that in future foundry deals will be taken “on a deal-by-deal basis not on an architecture-by-architecture basis . . . .even in areas where there may be some competition with businesses we’re in.”

In mobile, Intel is admitting embarrassment at its lack of success. “When we began our search for CEO a year ago, I was personally embarrassed that we had lost our way,” says Intel chairman Andy Bryant, saying that losing out to ARM in the mobile market “put us in a hole.”

Nonetheless Intel still won’t be putting its mobile processor Atom onto a leading edge process until 2015.

It was by insisting on putting its ARM-based X-Scale processors on trailing edge processes that doomed X-Scale to failure, but Intel still hasn’t learnt that lesson.

Maybe even a new CEO and an experienced chairman can’t override the entrenched interests inside Intel which insist that only PC and server chips go on the latest process.

Intel said that it would quadruple sales into tablets next year but will still only have flat revenues with 2013.

Intel’s bright spot for the next few years is an anticipated double digit annual growth in server processor revenues.

Business 2.5D package design tools available from GloFo, Amkor and Open-Silicon

Business 2.5D package design tools available from GloFo, Amkor and Open-Silicon

2013/11/22

GloFo, Open-Silicon and Amkor have come up with a functional 2.5D package test vehicle and the design tools, PDK, design rules, and supply chain are now in place and proven for interposer products from all three companies.

The jointly developed test vehicle has two ARM Cortex-A9 processors fabbed on GloFo’s 28nm-SLP attached to a silicon interposer, which is built on a 65nm manufacturing flow with TSVs to enable high-bandwidth communication between the chips.

Open-Silicon provided the processor, interposer, substrate, and test design, as well as the test and characterization of the final product.

GloFo provided the PDKs, interposer reference flow and manufactured both the 28nm ARM processors and the 65nm silicon interposer with embedded TSVs.

Amkor provided the package-related design rules and manufacturing processes for back-side integration, copper pillar micro-bumping, and 2.5D product assembly.

GLoFo and Amkor collaborated closely throughout the project to develop and validate the design rules, assembly processes, and required material sets.

The companies demonstrated first-time functionality of the processor, interposer, and substrate designs, and the die-to-substrate (D2S) process used by the supply chain resulted in high yields.
