1 . Ariel Procaccia has thought a lot about how to cut a cake over the last 15 years. As the father of three children, he knows how hard it is to divide a birthday cake to everyone’s satisfaction. But it’s also because Procaccia’s work focuses on exploring the mathematical rules for dividing stuff up fairly. One way to do that is to think abstractly about dessert.
For decades, researchers have been asking the seemingly simple question of how to cut a cake fairly. The answer reaches far beyond birthday parties. A mathematical problem at its heart, cake cutting connects strict reasoning to real-world issues of fairness, and so attracts not only mathematicians, but also social scientists, economists and more. “It’s a very elegant model in which you can distill what fairness really is, and reason about it,” Procaccia says.
The simplest approach is called the “divider-chooser” method, where one person cuts the cake into two equal pieces in his view, and the other person picks first. Each receives a piece that they feel is as valuable as the other’s. But when personal preferences are taken into account, even the easiest rule becomes complicated. Suppose Alice and Bob are to divide a cake, and Alice knows Bob prefers chocolate, she may knowingly divide the cake unequally so the smaller piece contains more chocolate. Then Bob will choose according to his preference, and Alice will get the larger piece. Both of them are satisfied with what they get, but the meaning of fairness changes in this situation.
The cake is a symbol for any divisible good. When cake-cutting principles are employed to settle disagreements, they are potentially helping the world find solutions. Procaccia has used fair division algorithms (算法) to model food distribution. Social scientist Haris Aziz is exploring situations ranging from how to divide up daily tasks to how to best schedule doctors’ shifts in hospitals.
Even after decades of investigation, cake cutting isn’t like a simple jigsaw puzzle (拼图) with a well-defined solution. Instead, over time, it has evolved into a kind of mathematical sandbox, a constructive playground that brings together abstract proofs and easy applications. The more researchers explore it, the more there is to explore.

2 . Search “toxic parents”, and you’ll find more than 38, 000 posts, largely urging young adults to cut ties with their families. The idea is to safeguard one’s mental health from offensive parents. However, as a psychoanalyst (精神分析学家), I’ve seen that trend in recent years become a way to manage conflicts in the family, and I have seen the severe impacts estrangement (疏远) has on both sides of the divide. This is a self-help trend that creates much harm.
“Canceling” your parent can be seen as an extension of a cultural trend aimed at correcting imbalances in power and systemic inequality. Today’s social justice values respond to this reality, calling on us to criticize oppressive and harmful figures and to gain power for those who have been powerless. But when adult children use the most effective tool they have—themselves—to gain a sense of security and ban their parents from their lives, the roles are simply switched, and the pain only deepens.
Often, what I see in my practice are cases of family conflict mismanaged, power dynamics turned upside down rather than negotiated. I see the terrible effect of that trend: situations with no winners, only isolated humans who long to be known and feel safe in the presence of the other.
The catch is that after estrangement, adult children are not suddenly less dependent. In fact, they feel abandoned and betrayed, because in the unconscious, it doesn’t matter who is doing the leaving; the feeling that remains is “being left”. They carry the ghosts of their childhood, tackling the emotional reality that those who raised us can never truly be left behind, no matter how hard we try.
What I have found is that most of these families need repair, not permanent break-up. How can one learn how to negotiate needs, to create boundaries and to trust? How can we love others, and ourselves, if not through accepting the limitations that come with being human? Good relationships are not the result of a perfect level of harmony but rather of successful adjustments.
To pursue dialogue instead of estrangement will be hard and painful work. It can’t be a single project of “self-help”, because at the end of the day, real intimacy (亲密关系) is achieved by working through the injuries of the past together. In most cases of family conflict, repair is possible and preferable to estrangement—and it’s worth the work.

3 . Those who had the pleasure of watching Benny Goodman at work saw a rather ordinary-looking man in rimless glasses and a conservative business suit; but they also saw a human being who could play the clarinet(单簧管) like no one before or since. This made Benny Goodman a unique individual.
Other Americans who have stood out from the flock include Joe DiMaggio, Beverly Sill, Ernest Hemingway and Jonas Salk. They, like Benny Goodman, were recognized and honored for no other reason than excellence.
It is doing something better than other people that makes us unique. Yet a surprising number of people still see individuality as a surface thing. They wear garish clothes, dye their hair strange colors and decorate their skin with tattoos to make some kind of social statement. But an ordinary guy who has dyed his hair purple or orange is nothing more than the same person with a funny-looking head.
The whole purpose of individuality is excellence. Those who invent, who improvise(即兴发挥), who know more about a subject than other people do, and who take something that doesn’t work and make it work––these people are the very soul of capitalism.
Charles Kettering didn’t like the idea of cranking a car to make it start, so he invented the electric starter. Henry Ford figured out the assembly-line technique and made it possible to mass-produce automobiles, and Elisha Otis, inventor of the elevator, indirectly created the city sky-line. These people understood that individualism means working at the top of one’s capacity.
The ones with the purple hair and the funky jewelry are just along for the ride, trying to be “different” and not knowing how to go about it.
The student who earns straight A’s on his report card has grasped the idea and has found the real meaning of individuality. So has the youngster who has designed his own spaceship, who gives piano recitals, who paints pictures of the world around him.
Benny Goodman understood it too. This is why he was at his best, blowing his clarinet, in a blue suit and black shoes.
1. The author mentions the appearance of Benny Goodman to _________.| A．show what a talented musician should look like |
| B．introduce an important figure in the musical world |
| C．contrast with his talent in music performance |
| D．indicate that he can’t stand out from the flock |
| A．an individualist tends to seek difference both in character and appearance |
| B．the essence of individualism lies in pursuing excellence to the full |
| C．being different in appearance is the very first step to being individual |
| D．those who strive to win the recognition of others are real individualists |
| A．A scientist who conducts research solely advancing knowledge for the greater good rather than for personal recognition. |

| C．examples and conclusion | D．comparison and contrast |
4 . Pricing is managers’ biggest marketing headache. It’s where they feel the most pressure to perform and the least certain that they are doing a good job. All successful pricing efforts share two qualities: The policy combines well with the company’s overall marketing strategy, and the process is well-organized as a whole.
A company’s pricing policy sends a message to the market—it gives customers an important sense of a company’s philosophy. Consider Saturn Corporation (a wholly owned company of General Motors). Saturn wants to let consumers know that it is friendly and easy to do business with. Part of this concept is conveyed through initiatives such as inviting customers to the factory to see where the cars are made and sponsoring evenings at the dealership that combine a social event with training on car maintenance. But Saturn’s pricing policy sends a strong message as well. Can a friendly, trusting relationship be established with customers if a salesperson uses all the negotiating tricks in the book to try to separate them from that last $100? Of course not. Saturn has a “no hassle, no haggle” policy which removes the possibility of conflicts between dealer and potential customer. Customers have an easier time buying a car knowing that the next person in the door won’t negotiate a better deal.
Of course, there are typically many participants in the pricing process: Accounting provides cost estimates; marketing communicates the pricing strategy; sales provides specific customer input; production sets supply boundaries; and finance establishes the requirements for the entire company’s financial health. Input from diverse sources is necessary. However, problems arise when the philosophy of wide participation is carried over to the price-setting process without strong coordinating mechanisms (协调机制). For example, if the marketing department sets list prices, the salespeople negotiate discounts in the field, the legal department adjusts prices if necessary to prevent breaking the laws or contractual agreements, and the people filling orders negotiate price adjustments for delays in shipment, everybody’s best intentions usually end up bringing about less than the best results. In fact, the company may actually lose money on some orders.

5 . A funeral or an obituary (讣告）is traditionally how we honor those who have died. But the way we remember loved ones is changing, as thousands of families turn to one project using TikTok and a surfboard.
Since the death of his father Randy Mendioroz, Tony Mendioroz dreamed of reuniting him with the place that he loved most—the ocean. Randy’s life revolved around water. He was a specialist in building water parks, wave machines and swimming pools, and Tony once worked for him for a while. The Mendioroz family were also regulars at the coast and spent wonderful time from some of San Diego’s best beaches.
Randy passed away from liver cancer in 2013. Feeling lost, Tony began to search for ways to feel a connection with his dad again. He found comfort in the sea and surfing, but always felt it was an experience he should have shared with his father. So, when he came across a video of a man offering to grant Randy “one last wave”, he jumped at the chance.
The man behind the video was surfer Dan Fischer. He, too, had lost his father Karl Fischer to cancer and had turned to the ocean to feel closer to him. After one unforgettable trip into the waves off the coast of Newport, with his father’s name written on his surfboard, Dan realized the potential healing power this simple activity could have when dealing with loss.
“Through surfing, I took him out there because he always loved the ocean, and he and I were adventure buddies,” Dan says.
When he got back to the shore, Dan posted a TikTok video, encouraging others dealing with grief to reach out and have the names of their lost loved ones written on his surfboard.
The Mendioroz family were one of thousands of those who got in touch from around the world, sparking the beginning of the “One Last Wave Project”.
The project prompted Dan to document each of his trips to the beach as names continued to cover his board. It has been a powerful force in creating a global community and support network for those going through loss.

6 . Around the globe, about 1 in 4 adults says they’re lonely. And the consequences of long-term social disconnection can be everything from an increased risk of heart attacks to dementia (痴呆). The following offers a road map to make connections.
Be curious. It’s easier to connect with people if you have shared interests or experiences, so start paying attention to what’s in your mind. What motivates you? What excites you?
Make something. When experts advise making something, people will say, “Well, I’m not Picasso. I don’t know how to do a fancy painting. ” Of course, you’re not!
Find a group that matches your interests. Whether it’s volunteering fora cause or playing frisbee (飞盘), try to find others who share your interests. There’s even an online group that has a quirky shared interest: a fascination with brown bears in Alaska, which led to Fat Bear Week. In interactions with others, you can begin to reveal yourself and share the unique things that matter to you.
Other people’s loneliness matters too.
| A．Pour out your hard feelings. |
| B．Loneliness can be infectious. |
| C．Take a risk by having conversations. |
| D．You should tolerate the risk of being lonely. |
| E．But the opportunities for creative expression are endless. |
| F．Knowing yourself can be a first step to bonding with others. |
| G．Then, other people recognize that and share their story in return. |
7 . Business innovation is an organization’s process for introducing new ideas, workflows methodologies, services or products. Like IT innovation, which calls for using technology in new ways to create a more efficient and agile organization, business innovation should enable the achievement of goals across the entire organization, with sights set on accomplishing core business aims and initiatives. Innovation often begins with idea generation, wherein ideas are narrowed down during brainstorming sessions, after which leaders consider the business viability, feasibility and desirability of each idea. Business innovation should improve one existing products, services or processes; or it should solve a problem; or it should reach new customers. Recent examples of business innovation include the introduction of the Dyson vacuum cleaner, whose creator and namesake James Dyson declared in advertisements that he set out to build a better product by applying industrial cyclone technologies to the household appliance.
The purpose of the business innovation process is to create value for the organization. That value can come from creating new revenue opportunities or driving more revenue through existing channels; from creating efficiencies that save time, money or both; or from improvements to productivity or performance. In short, innovation should lead to higher profits. Additionally, the results of an organization’s innovation process should yield a competitive advantage; it should help the organization to grow and reach — or, better still, exceed — strategic objectives.
Innovation and invention are closely linked, but the two terms are not interchangeable. An invention is an entirely new creation. The process of business innovation can produce an invention, but the term is broader in scope and includes the application of an existing concept or practice in a new way, or applying new technology to an existing product or process to improve upon it. To better understand the difference, consider this: The telephone is an invention, but the smartphone is an innovation.
Business innovation can also be classified as either revolutionary or evolutionary. Revolutionary business innovation yields a drastic change in a product, service, process, etc., which often destroys or supplants an existing business model. This is also known as radical Evolutionary or incremental innovation involves smaller, more continuous innovation, improvements that, while important, are not drastic enough to shift a company or market into a new paradigm. Disruptive innovation is a category that emphasizes the destructive aspect of revolutionary innovation; this term applies to business innovation that leads to the creation of a new market that displaces an existing one or, similarly, a significant upheaval in a category of products or services.
Business innovation, like most business initiatives, has both benefits and risks. Organizations should recognize on the negative side that the business innovation process can be a costly undertaking that does not always produce a return on investment (ROI); that idea considered likely to succeed could still fail; and that stakeholders could fight the changes required to be successful. On the other hand, organizations need to weigh those risks against the benefits of business innovation.

Should Writers Be Paid for Their E-books Lent by Libraries?
When libraries lend books to the public, authors and publishers receive remuneration from the Government under the Lending Rights schemes.
This year, the government has distributed almost a $ 22 million under these Public Lending Rights and Educational Lending Rights Schemes. For each book in public library collections creators receive $2.11 and publishers receive $0.52.
The amount that each claimant receives is often not very significant, with the majority of authors receiving between S100-500 annually, Still, a previous study has revealed that this remuneration constitutes the second most important source of income for creators from their creative work.
E-books, however, are not covered by these Lending Rights schemes.
One of the main reasons why e-books are not covered is that e-book lending is quite different from print book lending. In case of print books, authors and publishers are arguably losing on customers and revenues when libraries loan their books for free.Creators only receive $2.11 and publishers receive $0.52 for each book in public library collections.
At present, in the case of e-books, many publishers chose not to sell these books to libraries.
While publishers charge libraries high prices for e-books, writers complain that these amounts do not reach them. Publishing contracts often don't specify whether and how much authors receive for e-books sales or for e-lending.
| A．However,this is not the case when libraries lend e-books. |
| B．This may not be a big issue now, for e-books are minor in publishing. |
| C．Also, publishers assume get more profits from libraries where readers pay them more. |
| D．Publishing contracts often don't specify whether and how much authors receive for e-books sales or for e-lending. |
| E．Extension alone would do little if the current funds under the schemes were merely re-distributed from books to e-books. |
| F．For this reason, authors and publishers have been talking the Government into extending the Lending Rights Schemes to e-books. |
9 . Jackdaws (寒鸦) are the smallest member of the crow family. They often live in a crowd. Indeed, when cold weather comes, they gather in the hundreds (and sometimes thousands) every evening so that they can sleep in the same place. If you’ve ever heard jackdaws during their evening gatherings and morning departures, you’ll know they are not quiet birds. Despite being fairly low-volume during the day, they are really loud on either side of their night-time get-togethers. Why might this be?
A team of the Cornish Jackdaw Project set out to determine why jackdaws are so noisy before they depart from their sleeping spot. The team’s theory was that the morning calls might be a jackdaw version of “voting”. The researchers suspected that each individual’s call might count as an “I’m in!”. When a certain amount of “I’m in!”s are called —and so a certain volume of noise is reached -the group might then depart as a unit.
To test this idea, the researchers artificially increased the level of calls during the jackdaws’ natural morning calls. Their expectation was that, if jackdaws really are “voting with their voice” to decide when to depart the sleeping site, artificially adding calls would make them leave earlier than they naturally would have done. Subsequent experiments confirmed their expectation. The team therefore showed that jackdaws use their calls as a sort of voting system.
You might wonder why this happens. The researchers suggest that individual jackdaws benefit from the voting system because they are less at risk of being killed and they can get more access to social information — such as where to find food.
So the loud calls of jackdaws in the morning are therefore not the pure chaos it sounds like. If you are ever being driven mad by the sound in the morning, you can find comfort in the fact that the louder they get, the sooner they will leave you in peace.

xMAP Technology: The Science
What is multiplexing? Multiplexing is a method for high-volume biomarker testing — or testing multiple analytes simultaneously within a single run-using a single sample volume. xMAP Technology is best-suited for testing 3-500 targets.
How does xMAP Technology work? xMAP Technology uses labeled micro-spheres or beads, allowing for the simultaneous capture of multiple analytes from a single reaction.Because of their small size and low density, xMAP micro-sphere-based assays exhibit virtual solution-phase kinetics during the reaction. The beads are individually read using an xMAP instrument.
What does xMAP mean? Multi-Analyte Profiling, where the “x” represents the biomarkers (such as proteins, nucleic acids, or polyacrylamides) that are being tested.
xMAP Beads
xMAP beads come in a variety of formats, including magnetic (MagPlex) and nonmagnetic ( MicroPlex) beads.
xMAp beads puss through a red laser, or LED, which excites the internal dyes to distinguish the microsphere set. Then, a green laser or LED excites the fluorescent reporter dye to determine the result of the assay.
