Like People, Vultures Get Set In Their Ways And Have Fewer Friends As They Age

Older Birds Tend To Have More Selective Friendships With Stronger Bonds and May Know Better Where To Find Food

— By Holly Ober | August 29, 2024

Key Takeaways:

Young griffon vultures move frequently between sleeping sites in different locations, interacting with many friends.

They get set in their ways as they age and roost in the same spots with the same individuals; older vultures follow the same paths.

Roosts act as information hubs; older vultures may have a more thorough knowledge of where to find food resources and less need to learn about them from other vultures.

If you’d rather be watching TV on your couch than dancing at the club, you might have something in common with aging griffon vultures. New research shows that young griffon vultures move frequently between sleeping sites in different locations and interact with many friends but get set in their ways as they age, roosting in the same spots with the same individuals. As moving between roosts becomes a grind, older vultures follow the same path, establishing movement routines, that are not seen in young vultures.

Younger vultures shy away from the most popular roosts, suggesting they might be intimidated by the older ones or that there’s a vulture equivalent of “Hey you kids, get off my lawn.”

The research, published in Proceedings of the National Academy of Sciences, shows that like many people, older vultures tend to have fewer, more selective friendships with stronger bonds. They may also have a more thorough knowledge of where to find food resources.

Eurasian griffon vultures, or Gyps fulvus, are large vultures that live in the Mediterranean, the Middle East and India. With wingspans up to 9 feet, they’re much larger than North American turkey vultures and bigger than bald eagles.

Finding food can be tricky for vultures because it depends on locating animal carcasses — an unpredictable and ephemeral source. When griffon vultures find a carcass, they tend to sleep or roost nearby and feed on it over a period of days. Roosting sites can thus be ‘information hubs,’ where vultures that recently fed signal to others about food sources; they then follow each other to carcasses and form friendships that help them stay in the loop about food.

The researchers wanted to know if an individual griffon vulture’s movement patterns and social behavior changed over the course of its life. They used GPS data from 142 individually tagged birds in Israel gathered over a period of 15 years to cross-reference the vultures’ ages with their movement and social interactions at roost sites.

“What we found was as they age, their loyalty to certain roost sites increases,” said co-author Noa Pinter-Wollman, a UCLA professor of ecology and evolutionary biology. “Young vultures check out many different roosts but in middle age, they start going repeatedly to the same places.”

The study showed young vultures sometimes returned to the same roost but usually chose different ones, rarely spending two nights in the same place. From young adulthood at around 5 years old through middle age, they spent about half their nights at the same “home” site and half elsewhere. In old age, they became true homebodies.

“When they are old, from the age of 10 onward, they no longer have the energy to be ‘out and about’ and return consistently to the same site,” said corresponding author Orr Spiegel of Tel Aviv University. “Those who were adventurous at the age of 5 became more sedentary by age 10.”

As the vultures grew older, the strength of their social bonds decreased as well for at least part of the year. The number of individuals they interacted with didn’t change with age — if they had five friends when young, they still had five when older. But the amount of time they spent with vultures outside of their close friend group plummeted. Older vultures spent most of their time with and roosted mostly with these close friends. Their movements also became more routine, eventually following a predictable pattern.

The study is unique because the researchers were able to track the movements and social behaviors of the same vultures for up to 12 nearly consecutive years over a 15-year period.

“We are able to show that the trends of individuals becoming more loyal to the same sites with age is not because the more exploratory individuals die earlier and live shorter lives, and the older, more sedentary individuals live longer lives,” said first author and Tel Aviv University postdoctoral fellow Marta Acácio. “Individuals actually change their behavior with age, and this has rarely been shown in nature for long-lived birds due to the difficulty of tracking individuals for such a long time.”

The research backs up findings from studies in other species that, with age, animals become more faithful to their known sites and routines — and potentially become more selective in their social relationships. These behaviors are commonly attributed to aging in humans and can help improve understanding of how animal populations move about in their environments and relate to other members of their species, as well as identify better ways to protect them from threats. For griffon vultures, this could mean better protection of important roosting sites and using knowledge about their social interactions to reduce the risk of poisoning.

“It looks like they just get set in their ways,” Pinter-Wollman said. “They’ve gathered information over the years, and they might as well use it. Carcasses are hard to come by and roosts are information hubs. Some roosts become popular for a reason; for example, they tend to be closer to reliable food sources and older vultures potentially monopolize these roosts.”

James Donaldson on Mental Health - Language that could be clues to suicide differ between men and women, study finds

by Holly Ober, University of California, Los Angeles Credit: CC0 Public Domain The suicide rate for men is about four times higher than for women. While men make up 50% of the population, they account for 80% of the suicides. Yet, suicide risk in men often goes unnoticed. Now new research may offer hope. A UCLA-led study of public health records has identified a vocabulary associated with events surrounding male suicides that could be useful in spotting individuals who need follow up care, and in improving public health messaging. The study, published in the American Journal of Public Health, examined 271,998 suicides over a period of 17 years in the U.S. National Violent Death Reporting System, a database maintained by the Centers for Disease Control and Prevention. Research revealed large differences in the language used in the database's police reports and public health records to describe the circumstances surrounding male and female suicides. Less than half of suicide decedents in the database had a documented mental health condition, and even fewer had evidence of having ever received mental health or substance use treatment. In addition, a much larger percentage of those who had received such treatment were women than men. Language related to mood, psychological state, and previous or ongoing treatment for mental health problems appeared far more frequently in the records of women than men. Words and phrases related to interventions, such as "intensive care unit," "therapy," and "welfare check," also appeared more frequently for women. These are the types of terms mental health professionals are trained to recognize as early warning signs of suicide. Words associated with male suicides, on the other hand, were far more likely to reference job loss, alcohol abuse, financial stress, and unusual behavior around the time of death. #James Donaldson notes:Welcome to the “next chapter” of my life… being a voice and an advocate for #mentalhealthawarenessandsuicideprevention, especially pertaining to our younger generation of students and student-athletes.Getting men to speak up and reach out for help and assistance is one of my passions. Us men need to not suffer in silence or drown our sorrows in alcohol, hang out at bars and strip joints, or get involved with drug use.Having gone through a recent bout of #depression and #suicidalthoughts myself, I realize now, that I can make a huge difference in the lives of so many by sharing my story, and by sharing various resources I come across as I work in this space.  #http://bit.ly/JamesMentalHealthArticleFind out more about the work I do on my 501c3 non-profit foundationwebsite www.yourgiftoflife.org Order your copy of James Donaldson's latest book,#CelebratingYourGiftofLife: From The Verge of Suicide to a Life of Purpose and Joy www.celebratingyourgiftoflife.com Link for 40 Habits Signupbit.ly/40HabitsofMentalHealth If you'd like to follow and receive my daily blog in to your inbox, just click on it with Follow It. Here's the link https://follow.it/james-donaldson-s-standing-above-the-crowd-s-blog-a-view-from-above-on-things-that-make-the-world-go-round?action=followPub The records related to men who did mention mental health struggles were less likely to note that the person received treatment, and when treatment was mentioned, they were more likely to add that the patient had been non-compliant. Male narratives also more often included a topic reflecting emergency or police-based interventions. Ten terms related to mental health that more often appeared in the narratives of men than women were: - chronic mental health conditions - undiagnosed - strange behavior - agitation - making mistakes - seeming like - cognitive difficulties - signals of mental and physical health issues - self-injury - cognitive indecision "Many studies have shown that men are less often diagnosed with or treated for depression and other mental health issues so it's not surprising we see fewer of those kinds of terms in the records," said co-author Vickie Mays, a UCLA professor of psychology and health policy and management. "What we've done is uncover a language of suicide that can help health care workers and others catch more men before they go through with it." The findings offer a new approach to understanding and identifying early warning signs for suicide by mining texts, possibly using artificial intelligence, for signals emitted by those close to committing suicide. "Health care workers could reach out to these people with offers of support, and the data could be used to train suicide hotline workers, first responders, and health care professionals to recognize and intervene with troubled men. The language could also be used in public health messaging and in workplace wellness programs," said Susan Cochran, a professor of epidemiology at the UCLA Fielding School of Public Health and the Department of Statistics and Data Science. Mays noted that women interact with the health care system more routinely than men, usually around reproductive health. These visits typically include screening for depression and can lead to referrals for treatment. "If a man is only going to a doctor every so often, there are fewer chances he'll be referred for treatment. We think that by identifying gendered language around suicide, we can get more help for men who need it," Mays said. "For example, interventions could be directed at a man who is distraught about losing a job, since that was one of the key indicators pointing toward suicide for men."

Oxygen, Copper ‘Scissors’ Make Cheaper Drug Treatments Possible - Technology Org

Oxygen, Copper ‘Scissors’ Make Cheaper Drug Treatments Possible - Technology Org

Drugs to treat cancer are often very expensive to produce, resulting in high costs for the patients who need them. Thanks to pathbreaking research by UCLA chemists, led by organic chemistry professor Ohyun Kwon, the price of drug treatments for cancer and other serious illnesses may soon plummet.

Drugs – illustrative photo. Image credit: Pixabay (Free Pixabay license)

One chemical used in some anti-cancer drugs, for example, costs pharmaceutical companies $3,200 per gram — 50 times more than a gram of gold. The UCLA researchers devised an inexpensive way to produce this drug molecule from a chemical costing just $3 per gram. They were also able to apply the process to produce many other chemicals used in medicine and agriculture for a fraction of the usual cost.

This feat, published in the journal Science, involves a process known as “aminodealkenylation.” Using oxygen as a reagent and copper as a catalyst to break the carbon-carbon bonds of many different organic molecules, the researchers replaced these bonds with carbon-nitrogen bonds, converting the molecules into derivatives of ammonia called amines.

Because amines interact strongly with molecules in living plants and animals, they are widely used in pharmaceuticals, as well as in agricultural chemicals. Familiar amines include nicotine, cocaine, morphine and amphetamine, and neurotransmitters like dopamine. Fertilizers, herbicides and pesticides also contain amines.

Industrial production of amines is therefore of great interest, but the raw materials and reagents are often expensive, and the processes can require many complicated steps to complete. Using fewer steps and no expensive ingredients, the process developed at UCLA can produce valuable chemicals at a much lower cost than current methods.

“This has never been done before,” Kwon said. “Traditional metal catalysis uses expensive metals such as platinum, silver, gold and palladium, and other precious metals such as rhodium, ruthenium and iridium. But we are using oxygen and copper, one of the world’s most abundant base metals.”

The new method uses a form of oxygen called ozone, a potent oxidant, to break the carbon-carbon bond in hydrocarbons called alkenes, and a copper catalyst to couple the broken bond with nitrogen, turning the molecule into an amine. In one example, the researchers produced a c-Jun N-terminal kinase inhibitor — an anti-cancer drug — in just three chemical steps, instead of the 12 or 13 steps previously needed. The cost per gram can thus be reduced from thousands of dollars to just a few dollars.

In another example, the protocol took just one step to convert adenosine — a neurotransmitter and DNA building block that costs less than 10 cents per gram — into the amine N6-methyladenosine. The amine plays crucial roles in controlling gene expression in cellular, developmental and disease processes, and its production cost has previously been $103 per gram.

Kwon’s research group was able to modify hormones, pharmaceutical reagents, peptides and nucleosides into other useful amines, showing the new method’s potential to become a standard production technique in drug manufacturing and many other industries.

The research was funded by the National Institutes of Health.

Astrophysicists confirm the faintest galaxy ever seen in the early universe

UCLA Newsroom By Holly Ober | May 31, 2023 An international research team led by UCLA astrophysicists has confirmed the existence of the faintest galaxy ever seen in the early universe. The galaxy, called JD1, is one of the most distant identified to date, and it is typical of the kinds of galaxies that burned through the fog of hydrogen atoms left over from the Big Bang, letting light shine…

Okay, I had a little look and apparently this jukebox that only plays one tune is interesting enough to make international news.

A transcript from the English article and more thoughts about this under the cut!

I can't say it's really interesting, I'm just sharing my observations.

Everyday It's a gettin' closer A strange phenomenon has got the locals of The Resurrectionist pub in Edinburgh scratching their heads and tapping their feet. For no matter what song they put on the pub's jukebox, it will only play one tune: Buddy Holly's Everyday. Proprietor Mr. Tulloch is at a loss to explain it. "I took over The Resurrectionist over twenty years ago and the jukebox was installed by the previous landlord, and it has never given us a moment's trouble until recently. My regulars noticed that all the records seem to have changed into this Buddy Holly song! I'm quite partial to a bit of Buddy Holly myself but everyone in the pub is getting a bit scunnered of it, to be honest with you." Asked what he thinks could possibly be behind the phenomenon, Mr Tulloch is completely stumped. "Of course, I naturally assumed that this was a prankster at work but I've taken to sitting up all night and watching ober the --- whenever I put new singles -------- honestly swear that no-one ------ "Everyday". I've had the engineer out umpteen times, but he says that it's never been tampered with and can't explain it either. it cost me a fortune in visits." News of the strange occurrence is beginning to spread and Mr Tulloch admits that people are starting to turn up at the pub to check it out for themselves. "I was worried at first that people would be put off. There is only so much of one song you ---But now we're getting folk ---- wanting to see for themselves." Maybe too much of a good thing is good for business after all.

Then more English articles are set in focus after we see the article Aziraphale is reading.

"Hidden cameras show nothing"

Why are the newspapers so insistent on reporting about this? There's at least two English ones (assuming the "Scots Holly Day Mystery Deepens" one is more of an update on the situation, which is implied by the headline I'd say), and behind the English articles we can see a glimpse of international newspapers - I assume it to be the Chinese article we see in another frame, though it might also be Japanese.

So this has crossed the UK borders. And not only that, it's being reported internationally. The top left is a Vietnamese newspaper. The small segment at the top is Polish, the snippet on the right is Romanian (at least according to Google Translate).

The aforementioned Chinese and a Norwegian article.

As Aziraphale grabs the article from a German newspaper (that I would've loved to see in focus so I could read and translate it!) we see the Vietnamese, as well as Chinese, Norwegian and a Korean and French cutout.

But wait.

"Eden Tag nähert es sich... dem Wahnsinn des Wirts!" (Eden day it's getting closer... to the proprietor's insanity!")

That's not proper German. It's supposed to be "Jeden Tag", to reflect the lyrics of the song "Every day it's getting closer..." But they put "Eden". Given Google Translate did well enough translating the articles in other languages, I assume they are all written properly in their respective language. (by the way, it seems like the articles in other languages didn't disclose any new information compared to the one I've transcribed, but I'm sure people who actually know the languages can say more abouth that :D)

Would this make sense for the newspaper to put this in? Not really. So it must be a deliberate choice by whoever decided on these articles to appear in this little sequence.

Now, it could just be a little nod to the fact that Eden is a part of the story of Good Omens, and maybe it is. But I suspect more. Or maybe the newspaper just did a Freudian typo, I guess.

I'm still baffled as to why this would make the news worldwide. In some jukebox-enthusiasts magazines, maybe, but in big newspapers? Why?! Must be an extremely slow day for news if a funny jukebox is interesting enough to be reported about.

The only other explanation I can come up with is that Gabriel wanted to shout his love into the world and either miracled the interest into this particular jukebox or the articles themselves.

has anyone dissected the scene in s2e2 (?) when aziraphale reads up on the "everyday it's getting closer" thing in the international (!) newspapers? I can't imagine newspapers from all over the world just reporting on this funny jukebox in a pub in Edinburgh...

08/11/2020-Puttles Bridge/Aldridge Hill in the New Forest: 10 different pictures to those I tweeted earlier 

Today we walked in this area on a day that started rainy but it cleared up and the sun came out as the walk went on. It made it a third consecutive all-New Forest weekend for us I feel extremely lucky to be walking here at this time and am well and truly getting my fix of it. It was very much another walk through an enchanted forest today with very nice autumnal leaves scenes and lots of mushrooms, I took the first three and fifth pictures in this photoset of holly, a view, autumn leaves and a mushroom. I enjoyed seeing only my second ever amethyst deceivers lovely little purple mushrooms by a fence which has mushrooms growing out of its wooden stumps itself which was interesting which I tweeted a picture of I took the fourth picture in this photoset of the amethyst deceiver, my first ever deceivers were yesterday at Denny Wood though which made it interesting, and these ones if I’m honest were more purple the mushroom’s iconic colour than yesterday. I loved seeing them by the foot of trees again today. 

Bird wise we enjoyed seeing a lot of thrushes as we walked through the woods and out onto the heath at Aldridge Hill on the walk, it was particularly nice to see a group of Redwings flying over the trees a great bird of this time of year. Blackbird and Song Thrush were around too. It was also lovely to see a Raven in a tree. 

When out on the heath shown in the sixth and seventh picture I took in this photoset today, a bit of blue sky and sunshine came through and really lit up the heath it was fantastic to watch and I got some great photo opportunities over this vast landscape I took the ninth and tenth pictures in this photoset. Scenes I look forward to at this time of year with the sun setting earlier. We saw some nice cobwebs on the heath which looked especially great with raindrops on and then sun shining on them too which I took the eighth picture in this phootset of so these were great photo opportunities as well and very beautiful moments. Coming back through the trees along the Ober Water it was then nice to see a mist descend on the area which I tweeted pictures of tonight, creating very atmospheric scenes with New Forest ponies wandering through a lot too. A great weekend for keeping spirits up at this time I really enjoyed it. I hope you are all well or as well as you can be at this time. 

Wildlife Sightings Summary: Redwing, Blackbird, Song Thrush, Raven, Carrion Crow, Woodpigeon, Great Tit, a big group of Starlings around which was interesting we saw them as I tweeted a picture of before we went lined up on aerials visible on houses visible from my room as they seem to a lot in the rain and lots of Grey Squirrels I have seen so many this weekend fitting for autumnal days.

For books, I basically have a book or two that I’m actively reading in every room, and one on my phone as well. I bounce between them at will. I honestly think that that training of keeping multiple plotlines going at once is a big part of why I’m willing to ship multiple pairings in a fandom (even conflicting ones) and a part of why canon and fandom are distinct from each other in my mind-- My brain is accustomed to holding many conflicting truths all at once, and it never feels weird!

Ancestor of all animals recognized in Australian fossils

UC Riverside jeologları tarafından yönetilen bir ekip, şu anda en çok tanınan hayvanları barındıran ev ağacında birincil atayı buldu. Sanatçının Ikaria wariootia'yı canlandırması Ikaria wariootia olarak adlandırılan küçük, solucan benzeri yarat��k, en eski bilatiner veya arka ve ön, iki simetrik tarafa ve her iki bitimde de bağırsakla ilgili açıklıklara sahip bir organizmadır. Makale , Ulusal Bilim Akademisi Bildiriler Kitabı'nda açıklanmıştır .

Süngerler ve alg matları ile karşılaştırılabilecek en eski çok hücreli organizmalar değişken şekillere sahipti. Toplu olarak sıklıkla Ediacaran Biota olarak adlandırılan bu grup, karmaşık, çok hücreli organizmaların en eski fosillerine ev sahipliği yapar. Bununla birlikte, bunların çoğu genellikle hemen şu anda yuvarlak olan hayvanlarla ilişkili değildir, genellikle Dickinsonia adı verilen ve çoğu hayvanın birincil seçeneklerinden yoksun, bir ağız veya bağırsakla karşılaştırılabilir olan zambak yastığı şeklindeki yaratıklarla birlikte. İkili simetri olayı, hayvan yaşamının evrimi içinde vazgeçilmez bir adımdı ve organizmalara bilerek manevra yapma esnekliği ve vücutlarımızı yönetmek için standart, ancak karlı bir yöntem verdi. Solucanlardan böceklere, dinozorlara, insanlara kadar bir karmaşa, bu benzer birincil bilateri fiziği planı etrafında örgütlenmiştir. Evolutionary biologists learning the genetics of contemporary animals predicted the oldest ancestor of all bilaterians would have been easy and small, with rudimentary sensory organs. Preserving and figuring out the fossilized stays of such an animal was considered troublesome, if not unattainable. For 15 years, scientists agreed that fossilized burrows present in 555 million-year-old Ediacaran Interval deposits in Nilpena, South Australia, had been made by bilaterians. However there was no signal of the creature that made the burrows, leaving scientists with nothing however hypothesis.

Bunlar UC Riverside'den şu an doktora mezunu olan taş Scott Evans'daki Ikaria wariootia izlenimleridir ; ve jeoloji profesörü Mary Droser, bu yuvaların birkaçına yakın minik, oval izlenimler gördü. Bir NASA ekzobiyoloji hibesinden fon sağlayarak, belirli bir kafa ve kuyruğu ve hafifçe yivli kasları olan silindirik bir fiziğin ortak, sabit formunu ortaya çıkaran üç boyutlu bir lazer tarayıcı kullandılar. Hayvan 2-7 milimetre uzunluğunda ve yaklaşık 1-2.5 milimetre genişliğindeydi, en önemlisi bir pirinç tanesinin ölçeği ve şekli - sadece yuvaları yapmak için uygun boyut. Evans, "Bu hayvanların bu aralık boyunca var olması gerektiğini düşündük, ancak her zaman kabul etmekte zorlanacaklarını anladık." "3D taramalar yapılır yapılmaz, önemli bir keşif yaptığımızı biliyorduk." UC San Diego'dan Ian Hughes ve Güney Avustralya Müzesi'nden James Gehling'i bünyesinde barındıran araştırmacılar, arazinin eşsiz muhafızlarını kabul etmek için adlandırılan Ikaria wariootia'yı anlatıyorlar. Cins tanımlaması, Adnyamathanha dili içinde "toplanma yeri" ni öneren Ikara'dan gelmektedir. İngilizcede Wilpena Pound olarak tanımlanan bir grup dağın tanıması Adnyamathanha'dır. Tanımlanan türler Flinders Range'den Nilpena İstasyonu'na uzanan Warioota Deresi'nden geliyor. "Burrows of Ikaria happen decrease than the rest. It is the oldest fossil we get with any such complexity," Droser mentioned. "Dickinsonia and different large issues had been in all probability evolutionary lifeless ends. We knew that we additionally had numerous little issues and thought these might need been the early bilaterians that we had been in search of."

Belirli bir kafa ve kuyruğu ve hafifçe yivli kas sistemi olan silindirik bir fiziğin ortak, sabit formunu sergileyen bir 3D lazer taraması , nispeten kolay formuna rağmen, Ikaria bu dönemdeki farklı fosillerle karşılaştırıldığında karmaşıktı. Doğal zemini arayan ve temel duyusal yetenekleri gösteren, okyanus zeminindeki iyi oksijenli kumun sıska katmanlarına gömüldü. Ikaria'nın derinliği ve eğriliği, yuvalarda keşfedilen yönlendirilmiş hareketi destekleyerek açıkça farklı giriş ve arka uçları sembolize eder. Çukurlar ayrıca çapraz olarak "V" şeklindeki sırtları korur, bu da Ikaria'nın kas dokusuna fiziği boyunca, peristaltik hareket adı verilen bir solucan gibi kasılarak hareket ettiğini gösterir. Çukurlar içindeki tortu yer değiştirmesinin kanıtı ve organizmanın gömülü doğal maddeyi yediğini gösteren Ikaria'nın tüm olasılıklarda ağız, anüs ve bağırsak olduğunu ortaya koymaktadır. Droser, "Evrimsel biyologların öngördüğü budur." “Aslında şu anda tahmin ettiklerimizle izleri çok düzgün bir şekilde keşfettiğimiz heyecan verici.” Oluşturan: Holly Ober | Tedarik: California Koleji, Riverside

First survey of California's bees in 50 years will look for effects of habitat destruction

First survey of California’s bees in 50 years will look for effects of habitat destruction

When you think of California in the 1970s, maybe you think of hippies, Fleetwood Mac or skateboards. But if you’re an entomologist, you might think of all the natural spaces that have since been devoured by urbanization and wonder what happened to the native bees that lived in them.

The question isn’t one of mere nostalgia or curiosity. Insect populations around the world are plunging…

Should employees choose their tasks?

- By Holly Ober , UC Riverside -

Letting employees select their own tasks is a popular means of increasing work satisfaction. However, managers should also consider the nature of the task and the employees’ specialization before letting them select their own, suggests a new study led by University of California, Riverside and published in Organization Science.

Traditionally, managers allocate tasks to employees who are expected to produce a defined output. As organizations must increasingly respond to markets and opportunities quickly and decisively, they have begun to experiment with letting employees choose their own tasks. There is to date little hard data, however, to help managers determine the best task-allocation strategy to optimize worker productivity and satisfaction, and the organization’s success.

Marlo Raveendran, an assistant professor of management in UC Riverside’s School of Business and the A. Gary Anderson Graduate School of Management, led an international team of researchers who studied when and why self-selection may outperform allocation of work by a manager within an organization. They found that manager-led allocation tends to perform better than self-selection when employees have a broad skill range, tasks are highly interdependent, and coordination requirements are high. Self-selection tends to perform better than managerial allocation when employees are highly specialized, tasks are fairly independent and when new workers join a firm or project over time.

“We tend to think of the upside of self-selection as providing greater motivation for employees and better information on their own skills,” Raveendran said. “However, we found that even in the absence of motivational and informational considerations, self-selection can outperform managerial allocation depending on the employees’ degree of specialization and the nature of work.”

The researchers developed an agent-based model to see whether self-selection may have performance benefits over managerial allocation even in the absence of heightened job satisfaction. The model showed the skill-to-task fit tends to be higher under self-selection than under managerial allocation, but at the cost of over- and under-staffing of tasks. In self-selection, employees often pick their tasks without considering other employees’ skills, while managers may give away a task to an employee today for which a better-skilled employee may come along later.

The trade-off between self-selection and managerial allocation rests on a trade-off between interpersonal coordination failure under self-selection and intertemporal coordination failure under managerial allocation. This trade-off exists in addition to motivational and skill or information advantages that usually benefit self-selection.

“We provide a deeper understanding of the mechanism underlying the relative performance differences between self-selection and managerial allocation of employees to tasks that goes well beyond the expected motivational and informational advantages that intuitively characterize self-selection,” Raveendran said.  “The results of our analysis offer a window into the conditions under which each form of intraorganizational division of labor may have relative advantages.”

The research adds rigor to the question of when to use self-selection as a form of task allocation within organizations. Managerial allocation has many coordination advantages, but self-selection likely outperforms it under a confluence of specific conditions: When employees are very skilled but at only a narrow range of tasks, tasks are independent, and employee availability is unforeseeable.

The researchers hope these results can be used to inform, if not guide, managerial thinking on when and how to use self-selection as an allocation process within the firm.

Raveendran was joined in the research by Phanish Puranam of INSEAD in Singapore and Massimo Warglien at Ca’Foscari University of Venice in Italy.

Aim to Make Sodium Ion Batteries a Marketable Commodity - Technology Org

Aim to Make Sodium Ion Batteries a Marketable Commodity - Technology Org

Lithium ion batteries are the state of the art for energy storage, but much of the world’s lithium supplies lie outside the United States, making its use costly and subject to geopolitical constraints. Can Sodium Ion batteries become a marketable alternative?

A new Department of Energy center at UCLA, the Center for Strain Optimization for Renewable Energy, or STORE center, aims to improve batteries made from an alternative element that is one of the world’s most abundant: sodium.

Sodium ion batteries exist, but not in useful forms for most consumers. The batteries charge slowly, and their use life is shorter than that of lithium ion batteries. Lithium is preferred for batteries because it’s the smallest cation, or positively charged ion, that is not chemically reactive.

This quality enables it to move into and out of the battery’s cathode and anode without bumping into too many other atoms. The free movement of ions enable lithium ion batteries to charge quickly and with relatively few atoms pushed out of place, giving them a long use life.

Meanwhile, sodium is the next smallest cation but is much larger, meaning it faces more resistance as it moves through the material between the cathode and anode. The resistance deforms the arrangement of atoms in the material, making the battery charge slowly and giving it a shorter use life.

“We’re setting out to make sodium ion batteries a marketable commodity. Our goal is to get sodium batteries to where lithium is now within the next 10 years,” said center director Sarah Tolbert, a UCLA distinguished professor of chemistry.

“We are doing this by developing materials that have big spaces in them so sodium can move without forcing other atoms to rearrange, by engineering layers that resist rearrangement by sodium, and by making materials that are malleable and able to flex to accommodate volume change.”

Another big challenge is to ensure that all the other elements in the battery are also low cost. That requires moving away from traditional battery materials like nickel and cobalt, and instead focusing on low-cost elements such as iron, manganese, titanium, sulfur and phosphorous.

“The exciting challenge of this project is to solve fundamental materials problems in a practical space. When you can do that, it baecomes possible to both advance science and have a positive impact on society,” Tolbert said.

The STORE Center will receive $4.5 million over the next three years from the Department of Energy’s new Energy Earthshots program, which is investing $264 million to accelerate clean energy technologies within the next 10 years. The program recalls the wholesale mobilization of scientific and engineering talent called for by President John F. Kennedy in 1962, dubbed the Moonshot program, that put humans on the moon within the decade.

UCLA chemistry professor Xiangfeng Duan, materials science professor Bruce Dunn and chemical engineering professor Yuzhang Li also play key roles in the center. Collaborators include scientists from UCSB, the University of Southern California, Caltech and the Stanford Linear Accelerator Center.

Bats Play Key Pollinating Role for Durians

Known as the world’s smelliest fruit, durians are also essential to the farming economy of Indonesia. Although repulsive to many Western noses — some compare the smell to rotting trash — durians command the highest unit price of any fruit in Indonesia, with an export value of more than $250 million in 2013.Hoping to help improve the yield of small-scale farmers, three researchers decided to figure out what kind of creatures pollinate the durians in Sulawesi, a large island at the center of Indonesia. In a three-step process, the team first tested the plants to figure out what time of day pollination usually occurred. Evenings, they discovered, were prime time, as each flower opens for a single night and produces pollen only that one night.Then the researchers put bags on some of the flowers. Some bags had holes big enough for bugs but not larger creatures, and some had no holes at all. The bagged plants did not yield fruit, suggesting that something bigger than a bug was responsible for pollination.Finally, the researchers set up nighttime cameras to figure out which species of birds or bats was most responsible for the pollination. They reported Nov. 19 in the journal Biotropica that they caught three species of bats in the act, including a cave nectar bat and two types of flying foxes.The last two were a surprise, said Holly Ober, an associate professor and extension specialist at the University of Florida in Quincy. Flying foxes are known to eat fruit smaller than durians and are often killed by farmers trying to protect their mango crop.Showing that the flying foxes are crucial for durian pollination suggests farmers would be better off finding another way to protect their mangoes, Dr. Ober said. Some people also kill bats to sell as bush meat. “Now that we know that these bats are important to helping farmers produce more durians, we can start getting the message out that folks should not be causing harm to these bats,” she said.One of the co-authors, a local scientist with the Wildlife Conservation Society, who goes by the single name Sheherazade, conducted the actual experiments. Dr. Ober, who visited at the beginning of the study to help guide the research, said she hoped Sheherazade would use the findings to “have a very strong voice” to help persuade policymakers to add new protections for bats.Joseph Walston, senior vice president for global programs at the Wildlife Conservation Society and Sheherazade’s boss, said that bats were often overlooked as key contributors to an ecosystem.“There is probably not a group of species in the world where the gap between how important they are and how much they’re cared for is so great,” said Mr. Walston, who describes himself as a “bat guy.”Bats come out at night and inspire horror stories, but “they are so utterly fundamental to our ecosystems, to our economies and to our health,” Mr. Walston said. And yet, they are rarely offered support and protection, he said. “This study really is trying to provide empirical evidence for why we as a community should do more for bats,” he said.

3. Either Apollo or Rosie. I really want them! X3

4. Wild World - Eloise, New Leaf - Del, New Horizons - Ankha or Jeremiah

5. Del, I would always talk to him first in New Leaf. Yeah he a grumpy boi, but he is best boi. I hope to get him in New Horizons :3

6. I thought it looked really cute. I really wanted to try it out because I thought a more simpler game would be best for me. So I bought New Leaf at the end of 2019. Now I consider it one of my favorite video game series.

7. It was originally gonna be Happy Home Designer, but a friend told me to get New Leaf instead because it would be a better starting game for me, and because I know now that Happy Home Designer is a spin-off. So I got New Leaf instead.

8. You mean like, game or themed console? My favorite game is currently New Horizons but I have a soft spot for New Leaf. My favorite themed console is either the Animal Crossing 3Ds or the Animal Crossing Switch. They both look really adorable :3

9. Either the cats or the bunnies :3

10. Peppy X3

11. I haven’t paid too close attention to the bushes, but the holly ones look cute

12. I like a lot XD. Tom Nook, Isabelle, K.K. Slider, Sable, Kapin’, Gulliver, Timmy & Tommy, etc.

13. Through other Nintendo games (Smash Bros., Mario Kart, etc.)

14. It’s helped me feel more relaxed after a tough day. And it’s helps with productivity and organization.

15. I have no clue tbh XD

16. The afternoon.

17. I haven’t played long enough to have participated in all of the events. (I do hate the current Bunny Day one going on in New Horizons. I JUST WANT FISH! NOT STUPID WATER EGGS!)

22. Either Apollo or Del

23. Rosie, Ankha, or Bunnie :3

24. Winter X333333

25. I focus more on the smaller stuff in my town/island rather than other shit XD

26. Again, anything cabin or log related :3

27. In New Leaf my bedroom is pretty small but cozy, In New Horizons, I’m trying to make my living room look as closely to a cabin living room as possible.

28. In New Leaf it’s Hans’, in New Horizons it’s Jeremiah’s.

29. I guess I would say sweet and determined lol

30. When the switch glitch was still around in New Horizons, I made a second switch account to add another villager to my island so I can do the glitch. Now I can’t get rid of that second villager XD

31. In New Leaf, it’s close to the train station and Town Hall. In New Horizons it’s at the highest part of the island and the furthest north. I wanted a cabin in the mountains.

32. No. idk if time traveling counts. But other that that, no.

33. Play the game how you want as long as it’s not affecting other people’s gameplay.

34. “Animal Crossing” by Cosmicosmo. Here’s the song: https://youtu.be/r1RbGxgsXqU

35. Probably the weather idk lol

36. Yeah, I’m currently working on drawing my villager in New Horizons and some of my friend’s avatars as well.

37. Not really.

38. I have no clue what this question means lol

39. I like him. He’s pretty chill. I like some of the K.K. Slider covers people are making with popular songs. My favs being ���Don’t Stop Me Now” and “Dancing Queen”. Here’s the person’s channel: https://www.youtube.com/channel/UC1JB0XkovQwI4yeZFdJJ1bg

40. Yes, but I’m too scared to so no. I heard people have done it and immediately regretted it, so I’m not doing it lol

41. Wild World - Ober (Because of Ober, Gatlinburg), New Leaf - Atlantic (Because of the Atlantic Ocean), New Horizons - Gatlinburg (Because of Gatlinburg, Tennessee)

42. No. The fossils are close to being complete. I think I completed the fossils in New Leaf though.

43. Either the Agrias Butterfly or the Orchid Mantis

44. My favorite river fish is the loach. My favorite ocean fish is the BLUE TANG AAAA

45. OCEAN FISHING ALL THE WAY!

46. Nah. And not really.

47. Sadly no. My friends plan to visit soon tho :3

48. M I R A ! (Sorry if you like her, I’m just pissed she replaced Francine)

49. Huh?

50. I like Happy Home Designer. It’s not my favorite, but it’s fun to decorate other people’s homes. It deserves more love. (Unlike Amiibo Festival)
