first_img This year, the trend continues with the loss in sales in smaller retailers and the declining sales of smaller titles. This has a huge influence on the overall sales numbers; there were more than 8,000 fewer retail accounts being serviced in the first quarter of this year in contrast to last. The top ten chains in Q1 2015 represented 53.3 percent of total sales, compared to a collective market share of 51.8 percent in 2014. This is a trend that will likely continue as smaller retail stores exit the business. Although there will likely be no major turnaround in the foreseeable future, MagNet notes that decisions being made by publishers to reduce their allocations, partially driven by wholesaler demands for subsidies, are having a substantial impact on the steady sales decline. That comes in addition to the rise in social media and mobile technology in influencing how consumers view and absorb content. The Top 100 chains’ combined sales beat the overall business trends, which again indicates that the industry is losing smaller retailers. But the publishers who performed well in the first quarter all followed the same formula: more releases. Many of these publishers also tacked on higher cover prices, like Penny Press, which had 13 percent more releases, and an average cover price increase of about 23 percent.  Time Inc.’s numbers benefitted from more book-a-zine releases under their THEI brand, as well as the higher cover price on People. Harris Publications also increased their number of releases and focused more on book-a-zine products. Overall, the average cover price of a unit sold in the first quarter increased by 36 cents (more than 7 percent). Two factors contributed to this jump: 1) higher cover prices on many of the weekly titles, and 2) the continued publisher focus on book-a-zines with cover prices startingat $9.99. These factors helped drive the average cover price on a unit sold to an all-time high, which is one of the few good signs for the industry—consumers are willing to pay higher prices for quality printed magazines. center_img Although it’s easy to fall back on saying “social media is to blame,” publishers also need to reassess their releases—how often to distribute and how much are they going to charge according to MagNet’s 2015 Q1 Newsstand Sales Results. Magazine unit and dollar sales improved slightly in the first quarter to declines of 14.2 percent and 8.3 percent, respectively, compared to drops of 15.6 percent and 9 percent in the prior quarter. The average dollar sales decline of the Top 25 titles was mitigated this quarter by the higher cover prices on the weekly titles. Even though the newsstand sales environment is bleak, decisions being made by publishers have a major impact. So keep producing quality content but perhaps release it in a higher quality product and quit reducing your allocations, as MagNet suggests doing the opposite has proven to only be beneficial.last_img read more

first_imgBihar Chief Minister Nitish Kumar (L) visits Shri Krishna Medical College and Hospital (SKMCH) as more than 100 children lost their life due Acute Encephalitis Syndrome (AES) in Muzaffarpur on 18 June 2019. Photo: AFPTen more children died Tuesday from a mysterious brain fever potentially linked to lychees, officials said, taking the death toll to 113 this month and sparking angry protests in India’s poorest Bihar state.Sixty children, mostly under the age of 10 and malnourished, are undergoing treatment after an outbreak of Acute Encephalitis Syndrome (AES) in Muzaffarpur district of the eastern state.Bihar health department official Ashok Kumar Singh told AFP that ten children died on Tuesday, taking the overall death count in June to 113.“Six children were discharged after being treated for AES,” Singh said.He warned that the toll may rise with fresh cases trickling-in, as dozens undergo treatment in packed hospital wards. Television images showed several children to a bed.On Tuesday, dozens of people gathered outside the main hospital in Muzaffarpur to accuse local authorities of acting too slowly and of not caring.The state’s health minister came in for particular criticism after asking reporters about the score in India’s cricket match against Pakistan on Sunday during a news conference on the crisis.“Bihar’s Health Minister Mangal Pandey seems more worried about cricket score than the death of children,” tweeted Randeep Surjewala of the opposition Congress party.Rabri Devi, another opposition figure, called the deaths “cold-blooded murder”.“Children are dying because of a lack of medicines and treatment,” she tweeted.Bihar Chief Minister Nitish Kumar Tuesday faced angry protesters as he made his first visit to the state-run Sri Krishna Medical College, where most of the children have died.Reporters were barred from entering the facility, and the families of sick children were kept away from the premises.Outbreaks occur annuallyThe disease sets in rapidly and is characterised by plummeting blood sugar, high fever, convulsions and paralysis. It is caused by viruses, bacteria and toxins spread in different ways.Outbreaks have occurred annually during summer months in the same districts since 1995, typically coinciding with the lychee season.Apart from 2014 when a record 357 children died in the state, the annual death toll is usually much lower.Several years ago US researchers said the brain disease could be linked to a toxic substance found in lychees, the tropical fruit.They also said more study was needed to uncover the cause of the illness, known locally as Chamki Bukhar, which is fatal in a third of cases.The National Human Rights Commission has asked Prime Minister Narendra Modi’s government and Kumar state authorities to report any “possible flaw” in implementation of vaccination and awareness programmes.An editorial in the Hindu newspaper Tuesday said the deaths could have “easily been prevented with some foresight and early care”.It said in 2014 an Indo-US expert team had saved 74 percent of sick children through a simple medical intervention.“It is appalling that this year the government failed to raise awareness on this strategy.”Bihar is one of India’s poorest states and home to almost 100 million people. It has also been hit by a heatwave in recent weeks with temperatures of 45 degrees Celsius (113 Fahrenheit) that has left 91 people dead since the weekend.Most of the children affected by the brain fever come from poor families who struggle to get even one healthy meal a day. Often the kids gorge on free-growing lychees on an empty stomach.last_img read more

first_imgBy Renee Foose, Special to the AFROMost people would agree that being born into homelessness is not a good situation. Few, if any, would consider such a circumstance to be a blessing. However, one Baltimore native falls into the category of feeling blessed to have been born homeless to a single mom who struggled from alcoholism.  Richard Antoine White  has used his early life experiences to shape his journey from being cold, barefoot, hungry and alone in the Sandtown-Winchester community in West Baltimore to healthy, happy, educated, and playing symphony music on a world stage.Richard Antoine White (Courtesy Photo)Born to a single mom who battled addiction, White was often left alone to fend for himself as he wandered the streets looking for his mother. When searching for her, he’d also scan storm drains and sidewalks looking for spare change. “Eventually when I had a dollar, I would go buy chicken gizzards so I could eat,” White told the AFRO.  “I would keep gizzard meat under my tongue all day, to help with hunger.”White recalls sleeping under trees, and on park benches as a child not having reached school age. “There is a problem when everyone sees a child running around without shoes and sleeping in a park,” White said. He also has scars on his torso from being bitten by rats while sleeping, he said.After police found him sleeping on a very cold morning he was placed in foster care. His new foster parents were the same foster parents that raised his mother. and they were eager to adopt him. “He didn’t have much trouble adjusting, my children and the other children we had, helped him quite a bit,” said foster parent Richard McClain, Sr.   McClain, who is active in his church choir, doesn’t play an instrument but supported White’s desire to learn how to play music.  “We put him in school and he wanted to play music, so I got him a trumpet,” said McClain.Richard Antoine White (Courtesy Photo)Eventually a music teacher believed White had strong lungs and natural strength, so he was given a sousaphone, a lighter version of a tuba. White didn’t read music well, so he listened to cassette tapes of tuba players and practiced until he could mimic the sound.  “I played for fun with no real interest in being a musician,” White said. “I wanted to play football until I broke my hip in a street game, then I became more serious about playing music,” he said.When it came time to enter high school, White took his basic music skills and a borrowed sousaphone to audition for a seat at the Baltimore School for the Performing Arts. Unfortunately, he missed the audition date, and showed up to an empty school. Luckily for White, he was greeted by Chris Ford, the head of the music department.“He was an intriguing sight, a kid on crutches carrying a plastic sousaphone,” Ford told the AFRO.  Ford, now the director of Baltimore School for the Arts, said he chose to give White a chance to audition because he sensed White’s determination.  “He couldn’t sight read music, and his ability to sing back pitches was weak; but he had a way of manipulating sound in a meaningful way,” Ford said.  White was granted admission to the school and began playing the tuba.As he planned to further his musical talents, he worked as an usher at the Baltimore Symphony Orchestra. During concerts, White paid close attention to the principal tubist, David Fedderly.  “During performances, most ushers congregate in lobby areas; Richard didn’t do that. He’d stay and listen to the music and after the performance he would find me and ask questions,” Fedderly said.  “I knew he wanted to learn tuba and I knew he wanted to gain admission into a good college program to become a good musician,” Fedderly said. Fedderly, who also taught music, became White’s teacher at The Peabody Institute of Johns Hopkins University, where he worked closely with White to master the tuba. Upon earning his bachelor’s degree, White enrolled at Indiana University to pursue graduate studies. After just a few years, White earned a doctorate in tuba performance and became the first African American at Indiana University to do so.   The American Federation of Musicians report that African Americans make up less than four percent of symphony musicians world-wide, and White became one of the elites after accepting a one-year position with the New Mexico Symphony Orchestra (NMSO) in Albuquerque. New Mexico became his new home and he earned tenure with the orchestra, in addition to teaching at the University of New Mexico.In 2011, NMSO filed for bankruptcy and White was out of a job. The survival instincts he learned as a homeless child kicked in, and White did something few would consider. He met with university athletic staff and proposed a scenario to help the marching band with breathing techniques and choreography. “He saw an opportunity and presented a way how he could help the university,” said Chad Simons, associate professor and director of marching bands University of New Mexico.  White’s pitch worked, and he was hired as the assistant marching band director. “His motivation and positive message are powerful for nineteen-year-olds to hear,” said Simons.White is now a tenured faculty member at the University of New Mexico.  After the collapse of the NMSO, White was one of several musicians to form the New Mexico Philharmonic, where he is the principal tubist.His personal journey through destitution to doctoral studies only became widely known after two Baltimore-based filmmakers contacted Ford with an interest in creating a documentary about arts education being underfunded.  Darren Durlach and David Larson are the founders of Early Light Media. Their inspiring and award-winning films capture the human element in a way that compels viewers to be open to new perspectives.  When Ford suggested the filmmakers contact White, they were unaware of all the nuances of his journey, but quickly saw a powerful message.  “Our challenge in making the film was finding a way to tell the story in an authentic way,” said Durlach. “The story is one of persistence, and how a teacher can make all the difference in someone’s life,” he said.Durlach and Larson documented White’s journey and compelling message of hope, help and hard work. The film, RAW (White’s initials) Tuba is a contender for several independent film festival awards around the nation.White considers his journey a blessing and wants his message to inspire others to find hope, commit to a work ethic, and never give up.  To hear music performed by White, visit his web page at RawTuba.com.last_img read more

first_imgA Cotton-top tamarin at Schwerin Zoo. Credit: Harald Hoyer / Wikipedia. Citation: Research duo discover first instance of non-human primates whispering to each other (2013, September 25) retrieved 18 August 2019 from https://phys.org/news/2013-09-duo-instance-non-human-primates.html (Phys.org) —Psychology researchers Rachel Morrison and Diana Reiss of The City University of New York have discovered the first instance of non-human primates whispering to one another. In their paper published in Zoo Biology, the two describe how they recorded vocalizations of captive tamarin monkeys and found that when threatened they sometimes revert to whispering to one another to avoid being overheard. Explore further More information: Morrison, R. and Reiss, D. (2013), Whisper-like behavior in a non-human primate. Zoo Biol.. DOI: 10.1002/zoo.21099AbstractIn humans, whispering has evolved as a counteractive strategy against eavesdropping. Some evidence for whisper-like behavior exists in a few other species, but has not been reported in non-human primates. We discovered the first evidence of whisper-like behavior in a non-human primate, the cotton-top tamarin (Saguinus oedipus), in the course of investigating their use of human-directed mobbing calls. We exposed a family of captive cotton-top tamarins to a supervisor who previously elicited a strong mobbing response. Simultaneous audio–video recordings documented the animals’ behavioral and vocal responses in the supervisor’s presence and absence. Rather than exhibiting a mobbing response and producing loud human-directed mobbing calls, the tamarins exhibited other anti-predator behaviors and produced low amplitude vocalizations that initially eluded our detection. A post-hoc analysis of the data was conducted to test a new hypothesis—the tamarins were reducing the amplitude of their vocalizations in the context of exposure to a potential threat. Consistent with whisper-like behavior, the amplitude of the tamarins’ vocalizations was significantly reduced only in the presence of the supervisor. Due to its subtle properties, this phenomenon may have eluded detection in this species. Increasing evidence of whisper-like behavior in non-human species suggests that such low amplitude signaling may represent a convergence in a communication strategy amongst highly social and cooperative species. © 2013 Phys.org Whispering is a common strategy used by people to communicate with one or more people while simultaneously trying to avoid having others hear. Other animals have been found to lower the volume of their communications as well under certain circumstances, but never before has any primate other than humans been found to do so. In this new effort, the discovery was inadvertent.The two researchers were studying cotton-top tamarins at New York’s Central Park zoo, hoping to learn more about the kinds of calls the monkeys make to one another under different circumstances. Prior research had found that tamarins are capable of vocalizing a wide range of noises. Morrison and Reiss were most interested in what are known as mobbing calls—sounds members of a group make to confuse or intimidate predators.To better understand how the tiny monkeys use mobbing calls, the researchers recorded sounds a group made when a known threat entered the vicinity—a supervisor that had been part of the team that had captured them in the wild. Prior to the study, the monkeys had used mob calls whenever the supervisor came into their view. Neither of the researchers noticed anything unusual as recordings were made, but later during playback analysis they discovered the monkeys were engaging in vocalizations that were at such low amplitude that people in the area couldn’t hear them—they were whispering to one another.The researchers acknowledge that it’s impossible to know for sure what exactly the monkeys were saying to each other, but it seems pretty clear from observation that they were reminding one another of the threat the man posed and were doing it in a way that wouldn’t alert the threat to the calls they were making to each other. The discovery of whispering by a non-human primate, Morrison and Reiss suggest likely means that it occurs in other species as well—researchers just haven’t heard them yet.

first_imgOptical images of two types of MoTe2 monolayer samples: (a) MoTe2 flakes that were highly luminescent to begin with maintain their brightness over the 8-day observation period; (b) MoTe2 flakes that were weakly luminescent at the start fade within a few days, and parts of them seem to disappear altogether. Credit: Bin Chen, et al. ©2015 American Chemical Society Defects in 2D semiconductors could lead to multi-colored light-emitting devices The researchers, led by Sefaattin Tongay, Assistant Professor at Arizona State University, have published a paper on the changing luminescence in a recent issue of ACS Nano.”Currently, many researchers throughout the world are demonstrating very impressive and promising proof-of-concept applications using 2D material systems, but we still do not know their material stability over long periods of time,” Tongay told Phys.org. “This research presents the unique case of MoTe2, the only infrared-range TMD, where monolayers visually disappear but are physically still there.”Like other TMDs, MoTe2 stands out for its interesting optical properties. In bulk form, TMDs are not luminescent, but when one-atom-layer-thick flakes are exfoliated from the bulk, the 2D flakes become semiconductors and emit light rather strongly. For this reason, 2D semiconducting TMDs could have applications in optoelectronics and solar energy conversion technologies. As the only TMD that has an infrared-range band gap, MoTe2 is particularly suitable for infrared detectors and tunnel field-effect transistors.Because 2D materials have a large surface-to-volume ratio, their properties can be affected by interactions between their surface and the environment. Noting that tellurium compounds are particularly sensitive to oxygen, the researchers here wanted to investigate what happens when monolayer MoTe2 is exposed to oxygen for several days. The researchers propose that the reason why the weakly luminescent flakes seem to disappear is that they have a large number of defects, particularly vacancies due to missing atoms. These vacancies are why the flakes have a low starting luminescence, and also explain why they lose their luminescence when exposed to oxygen. Oxygen molecules (O2) from the air become embedded in these defects and bind to Mo and Te, forming “deep states” that basically trap electrons and holes, effectively prohibiting luminescence. On the other hand, flakes that are highly luminescent to begin with have a small number of defects, so they don’t absorb nearly as many oxygen molecules, don’t suffer loss of luminescence, and their optical properties remain close to their properties under vacuum conditions.”This work shows that a slim amount of defects in MoTe2 can have a great impact on their material properties, such as optical, electrical, and vibrational, and these changes occur gradually over time similar to aging wine: depending on the defect concentration, MoTe2 monolayers can spoil over time (or might get better),” Tongay explained.The results here show that the defects play a significant role in the optical properties and stability of MoTe2, and could also reveal insight into the environmental stability of other 2D materials, such as silicene (2D silicon), phosphorene (2D phosphorous), and other TMDs. It could also lead to ways to control these materials’ properties. (Phys.org)—When exposed to air, a luminescent 2D material called molybdenum telluride (MoTe2) appears to decompose within a couple days, losing its optical contrast and becoming virtually transparent. But when scientists probed further, they found that the disappearance is an illusion: the material remains structurally stable, and only its material properties change. The results reveal insight into the environmental stability and unusual properties of a newer class of 2D materials called transition metal dichalcogenides (TMDs).

However, atomic force microscopy measurements reveal that the material is indeed still there; it physically exists, and only its optical properties change. Credit: Sefaattin Tongay The researchers began by observing the material under an optical microscope with an infrared lens. They found that MoTe2 flakes that were highly luminescent to begin with maintained their brightness over the 8-day observation period. On the other hand, weakly luminescent flakes unexpectedly appeared to fade within 1-3 days, and parts of them disappeared altogether. However, when viewing the “vanishing” flakes using an atomic force microscope (AFM), which scans samples mechanically rather than optically, the researchers saw the flakes “reappear.” The flakes had never disappeared in the first place, but their optical properties had changed while their chemical structure was maintained.
