Charter schools and waiting lists in D.C. schools

When school choice procedures result in some children having multiple offers, others must wait for an assignment, which can be taxing. Even in cities that have begun to use single-best-offer school choice systems for the public schools, there can be a lot of congestion if the charter schools aren't integrated into the process. The Washington Post has the story:  Parents struggle with ‘wait-list shuffle’ in D.C. schools


"Thousands of seats change hands in the first weeks of class as students leave one school for another, a quiet migration triggered by the intense competition for a good public education in the nation’s capital.

"This is the wait-list shuffle. Parents say it’s a downside of the city’s school-choice movement — a nationally watched experiment that has given Washington families more options than ever but also has injected a new level of agony and instability into the start of the academic year.

"The change has been spurred by the rapid expansion of public charter schools, which operate outside the traditional school system and under different enrollment rules. As parents try to get their children into the best schools, they can apply to an unlimited number of them. Once admitted, students can hold seats in more than one school.

"Those parents seeking to preserve their options often relinquish the extras only when forced to on the first day of class. Principals then scramble to fill their rolls from long wait lists, recruiting students who are enrolled elsewhere. The cascading effect lasts into October.
...
"There has long been a scrum to win seats in the city’s best traditional public schools, but the rise of charter schools — which now enroll more than 40 percent of Washington’s 77,000 students, a larger proportion than any other city except New Orleans — has helped turn that scrum into a frenzy.

"A growing number of parents are entering lotteries for D.C. public schools, especially for pre-
kindergarten — but they are limited to six applications each year and can’t enroll in more than one at a time.

"The charter school process is a free-for-all: There are 57 different charter schools, and parents can enter as many lotteries as they like. Many track their options with elaborate spreadsheets, relying on word of mouth, test scores and gut feelings to identify favorites.
...
"Each year, lucky students win seats in more than one charter school, or one traditional school and several charters. Other families spend the summer months eagerly refreshing school Web sites, watching their children move slowly up long lists.

"This spring, the waiting lists for charter and D.C. public schools topped out at more than 35,000 names, many of them duplicates. 


"The lists begin to move during the summer, as families settle on choices or move away. Then they accelerate after the first day of school, when principals see who doesn’t show up and turn to their wait lists.

"According to the D.C. Public Charter School Board, 1,141 students withdrew from a charter school within the first month of classes in fall 2011. Another 2,671 entered a charter school within that same time frame.
...
"Parents who take multiple seats say they’re playing by the rules of the game and doing what’s necessary to get what’s best for their children.

"One mother of a kindergartner — who spoke on the condition of anonymity to avoid angering school officials and other parents — spent the first week of classes this fall holding slots at two of the city’s most coveted charter schools, weighing whether she could afford after-school care at the one she preferred."

30 years of the ultimatum game

Come celebrate in Cologne at the 2012 ESA European Conference, Sept. 12-15.

"In 1982 Güth, Schmittberger, and Schwarze published their seminal paper on the ultimatum game. The experiments were conducted at the University of Cologne. We will celebrate this 30th anniversary and invite submissions of papers that review insights from the ultimatum game and/or deal with new results. "

They also encourage submissions concerning "Bounded Ethicality."

The Keynote speakers are
• Max Bazerman (Harvard Business School)
• Urs Fischbacher (University of Konstanz)
• Werner Güth (Max Planck Institute of Economics, Jena)

Gastroeconomics

There has been a lot of interest in neuroeconomics lately, focusing on decision-making and the brain. But there are also a lot of neurons in the gut, which raises the possibility of a part of neuroeconomics that might be called gastroeconomics.

This Scientific American article brought all this to mind:
Microbes Manipulate Your Mind: Bacteria in your gut may be influencing your thoughts and moods

(This shouldn't be confused with the gastroeconomics associated with the market for gastroenterologists:)

The supply of American doctors

American medicine is a market with tightly restricted entry, at all levels. Proposed legislation offers a glimpse: Bill Would Create More Medical-Residency Slots, Potentially Easing Physician Shortage

"Legislation introduced in Congress on Monday would expand the number of Medicare-sponsored training slots for new doctors by 15,000, a step that two medical-education groups said would go a long way toward easing a projected shortage of physicians.

"The bill, the Physician Shortage Reduction and Graduate Medical Education Accountability and Transparency Act (HR 6352), is sponsored by Rep. Aaron Schock, an Illinois Republican, and Rep. Allyson Schwartz, a Pennsylvania Democrat.

"Medical schools have been expanding their enrollments and new schools have been opening up as concerns have grown about a shortage that could reach more than 90,000 physicians by 2020, according to the Association of American Medical Colleges.

"Those worries have intensified with passage of the Affordable Care Act, which will greatly increase the number of people seeking medical care by providing insurance coverage to 32 million more people.

"But while more students are making their way through the medical-school pipeline, they're likely to run into bottlenecks because of a cap on the number of Medicare-supported residency training slots that Congress imposed in 1997."

Medical internships in Australia are in short supply

Medical students languish in a critical condition

"The Australian Medical Students' Association estimates almost 500 students will miss out on an internship next year because of insufficient places. Under the internship system students must work for a year under supervision in a hospital before they can work as doctors.

"Recent changes to the application process have further complicated the situation in Victoria. International students will now have priority for internships over Victorian students who have studied interstate but want to return for hospital placements.
 ...

"Australian Medical Association president Steve Hambleton points to the curious situation where the nation has a shortage of doctors, yet there are too few internships. A report by Health Workforce Australia has forecast a shortfall of 2701 doctors by 2025.

"The placement system has fallen apart, he says, because the federal government regulates the number of students universities can enrol while its state counterparts oversee the provision of internships. ''Nobody's got the control levers for the pipeline,'' he says.

"A complicating factor has been the ability of universities to enrol an unlimited number of full-fee-paying international medical students without guaranteeing a hospital placement at the end of the course."

Fishery management in ancient Hawaii

Ancient Civilizations Reveal Ways to Manage Fisheries for Sustainability

"The authors of the study, titled "Multicentury trends and the sustainability of coral reef fisheries in Hawai‘i and Florida", point to the U.S. National Ocean Policy as an example of emerging attempts to manage ocean ecosystems more holistically, and local fisheries co-management as a modern way of including community members in designing effective fishing regulations. However, the authors caution that effective enforcement needs to go hand in hand with the development of local governance. “The ancient Hawaiians punished transgressors with corporal punishment,” observed Kittinger. “Clearly, we don’t recommend this, but it’s easy to see there’s room to tighten up today’s enforcement efforts.”

Unravelling of product announcements--ahead of the new iPhone

Lucas Coffman points me to the following unravelling story (which I figured I had better post without further delay :)  Rivals Jostle Before Apple Announces New iPhone

"...technology companies are watching every one of Apple’s moves — and scrambling to get out in front of them.

"Several major tech companies are cramming product announcements into this holiday-shortened workweek.

"Nokia and Motorola Mobility, former leaders in the mobile race who are now also-rans, have scheduled events for Wednesday at which they are likely to announce new smartphones. And the next day, Amazon is expected to introduce new Kindle devices.

"Sony and Samsung, among others, got a jump on things last week with announcements of new tablets and phones at a consumer electronics conference in Berlin.

"But next week, the tech event calendar is largely blank — with the exception of an Apple news conference that is said to be scheduled for Sept. 12, where the company will reveal its latest iPhone, according to a person briefed on the company’s plans, who declined to be named because those plans had not yet been made public.

“It seems that the rumor of an Apple announcement is having an effect on competitors’ announcements, unless it’s an amazing coincidence” that several events are scheduled this week and none the next, said Michael Gartenberg, a technology analyst at Gartner. "

Cass Sunstein on the regulator as market designer

Here's his essay: Empirically Informed Regulation
It was written while Sunstein was Administrator, Office of Information and Regulatory Affairs, Office of Management and Budget, Executive Office of the President. It focuses on what he sees as the lessons from behavioral economics.

"In recent years, a number of social scientists have been incorporating empirical findings about human behavior into economic models. These findings offer useful insights for thinking about regulation and its likely consequences. They also offer some suggestions about the appropriate design of effective, low-cost, choice-preserving approaches to regulatory problems, including disclosure requirements, default rules, and simplification.

"A general lesson is that small, inexpensive policy initiatives can have large and highly beneficial effects.  The purpose of this Essay is to explore relevant evidence, to catalogue recent practices and reforms, and to discuss some implications for regulatory policy. And while the primary focus is on small, inexpensive regulatory initiatives, there is a still more general theme, which involves the importance of ensuring that regulations have strong empirical foundations, both through careful analysis in advance and through retrospective review of what works and what does not."

School choice in Harlem

The Times reports on school choice in Harlem: School Choice Is No Cure-All, Harlem Finds

"Mayor Michael R. Bloomberg has made school choice a foundation of his education agenda, and since he took office in 2002, the city opened more than 500 new schools; closed, or is in the process of closing, more than 100 ailing ones; and created an environment in which more than 130 charter schools could flourish. No neighborhood has been as transformed by that agenda as Harlem.

 "When classes resume on Thursday, many of its students will be showing up in schools that did not exist a decade ago. The idea, one that became a model for school reform nationwide, was to let parents shop for schools the same way they would for housing or a cellphone plan, and that eventually, the competition would lift all boats.

"But in interviews in recent weeks, Harlem parents described two drastically different public school experiences, expressing frustration that, among other things, there were still a limited number of high-quality choices and that many schools continued to underperform."

Gender-pricing discrimination

The NYC Department of Consumer Affairs is on the case, the WSJ reports: City Nails Sex-Based Pricing.

Among the targets are salons that charge men and women differently for manicures and haircuts. But are those really the same products?

""It's ridiculous. I have some guys who need to come in every two weeks," said Ania Siemieniaka, the owner of Freckle Skin and Hair, which had to pay $175 for a violation. "If I raise my prices, I'll lose all my male customers."

"The city's Department of Consumer Affairs began stepping up enforcement of the law last year, when it issued 580 gender-pricing violations to businesses, more than double the 212 doled out the year before.

"We wanted to really send a strong message to businesses about this kind of illegal pricing, so we did a very focused sweep over the course of the year," said the department's commissioner, Jonathan Mintz. "That sweep was largely targeted at salons and barbershops and laundry and dry cleaning."

"Nearly all of the violations were the result of sweeps rather than complaints, said Mr. Mintz, because businesses and industry groups weren't correcting the practice on their own."

Uri Rothblum's intellectual legacies

The journal Linear Algebra and its Applications has published an article in memoriam of Uri Rothblum, who passed away in March of this year:   Uriel G. Rothblum (1947–2012) by Raphael Loewy.

The article has discussions of aspects of Uri's work by a number of his collaborators, one of whom is Hans Schneider, a longtime editor of LAA. I recently corresponded with Professor Schneider about the beginning of his long and productive collaboration with Uri, and (with his permission) here is some of that correspondence.

 Dear Professor Schneider: Eric Denardo shared with me the memoir of Uri Rothblum, and encouraged me to write a note to you about his very first interaction with you. My memory of it isn't all that clear.

It must have been in 1974 (the year that he and I graduated from Stanford) that you contacted him about his paper on nonnegative matrices. As I recall, your letter suggested that perhaps his results and some of yours should appear in collaboration. He wasn't sure that his English was up to the task of saying "no" in a diplomatic way, and so he asked me to help draft the letter, which explained that he had a special emotional attachment to that paper since it was a central part of his dissertation.

He valued enormously his subsequent collaboration with you, and never tired of telling me that the letter I had drafted for him might be the most productive piece I have written.

The world is certainly less complete without Uri in it.

All the best,

Al Roth

 Subject: Re: Uri's write-up in Linear Algebra and its Applications
 Dear AL,
 Thank you for your very interesting letter and  apologies for my slow reply. 
 ...

 But now to your remarks. You are right, I proposed that Uri and I combine our papers and he turned this  down. I did not know that you were involved until Eric told me this year.

 It was a good decision on his part and I need to thank you for your help to Uri.  The sequence of letters (mine, his) spectacularly achieved what I desired, viz. cooperation with a young mathematician who was interested in the same area as I. I think it is impossible for me to explain how mathematically isolated I felt at the time without sounding like a petulant child.

 BTW, I first saw Uri's paper #3 in early 1975. The correction is worth making for I spent calendar 1974 at  TU Munich and before I left my student Richman had essentially completed results for his Ph.D. which  were  waiting to be writtten up when I saw Uri's paper. That's the paper I offered to combine with Uri's. I recall that Uri said there was room for both papers; I wish I still had his letter. Richman-S finally appeared in LAMA in 1978.

 I have never again offered to make a joint paper of a submission to LAA, even when I felt I could improve it significantly. I got increasingly worried that this is crossing a line for an EIC.  (Full disclosure, there is another paper joint with me that was originally submitted by my co-authors, but it became joint at the suggestion of an editor when he saw my referee's report.)

 Finally , I am very glad to hear from you, AL, that Uri saw the events that brought us together so positively. To my recollection, we never discussed them in any meaningful way.

 best wishes

******************

Some quick recollections of my own, of an intellectual history sort.

Uri and I were office mates in grad school, and I often benefited from his advice. I recall one time in particular, when I needed to prove that a certain interval was compact, and he showed me a proof that allowed me to complete the theorem that formed the basis for my dissertation. I later realized that a corollary of his proof was that _every_ interval was compact, so unfortunately I had to use another proof (and I recall a tense week between weekly visits to my advisor, at the end of which I was able to say "there was a problem with the proof I outlined last week" instead of "...with the theorem...").

Uri and I didn't collaborate as grad students, but we eventually wrote four papers together:

Roth, A.E. and Rothblum, U. "Risk Aversion and Nash's Solution for Bargaining Games With Risky Outcomes," Econometrica, Vol. 50, 1982, 639‑647.

Roth, A.E., Rothblum, U.G., and Vande Vate, J.H. "Stable Matchings, Optimal Assignments, and Linear Programming," Mathematics of Operations Research, 18, 1993, 803-828. 

 Blum, Y., A.E. Roth, and U.G. Rothblum "Vacancy Chains and Equilibration in Senior-Level Labor Markets," Journal of Economic Theory, 76, 2, October 1997, 362-411.

Roth, A.E. and U.G. Rothblum "Truncation Strategies in Matching Markets--In Search of Advice for Participants," Econometrica, 67, January, 1999, 21-43.
  

The two two-author papers each began when, in the course of a long walk somewhere, I indicated that I was working on a problem that was too hard for me to solve.  The paper with John Vande Vate came about by combining two different such conversations. But the most unusual of the collaborations was initiated by Uri in connection with work he had started with his student Yossi Blum. I believe they figured out that a paper by Blum and Rothblum would look better if they had a third author named Roth.

Readers of this blog may already be familiar with his other papers on matching and market design:

Internet dating survey

Quantifying the Online-Dating Revolution

"The internet is especially important in “thin” dating markets, those in which people encounter a dearth of potential partners in their daily lives. That helps to explain the same-sex numbers and also why it’s not tech-savvy twentysomethings who make the most use of the internet, for romantic connections, but people in their 30s and 40s—another finding."

Bad market design by design at U of Central Florida...and Craigslist?

Course registration can be a pain, but at the University of Central Florida they apparently don't want anyone trying to make it easier: Student Is Punished for Creating Class-Registration Web

"A student at the University of Central Florida has been placed on academic probation for creating a Web site that tells students when a seat becomes available in a given class.

"Tim Arnold, a senior at Central Florida, built the U Could Finish site this year. The site became available in June, but, within days, was blocked from accessing the university site without notice. The Office of Student Conduct then told Mr. Arnold that he had violated university policy regarding technology use..."

It's easier to see how Craigslist might have a legitimate interest in preventing entrepreneurs from developing superior front ends (recall eBay vs. Bidder's Edge): The SF Chronicle has the story.
3taps, PadMapper face Craigslist challenge

"Kidd's 3taps and a website that uses the data it collects, PadMapper, are the latest in a long line of Web developers to face legal action from Craigslist, the San Francisco company that has dominated the online classified advertising market for 17 years. Since 2008, at least three dozen similar services such as MapsKreig, Craiglook and CraigsFish have received cease-and-desist letters from Craigslist, most for building websites that presented Craigslist listings in ways they considered to be more dynamic, visually appealing and helpful.
...
"Craigslist has never added features such as mapping, videos and mobile apps, or any other tools that would improve user experiences. It still sorts items in chronological order, and doesn't allow nationwide searches of all its local websites at once. Its reluctance to update its Web services has opened the door for Kidd and other developers like him.

"Some of the developers shut down by Craigslist pulled data directly from its website, but 3taps uses a novel approach - searching Craigslist through Google, copying the data off Google, reordering it and then formatting it in a way other websites can easily display. PadMapper uses content generated by 3taps for its mapping services.

"Kidd noted that Craigslist chooses to allow price, location and description information from listings to appear on Google. As a result, he said, it shouldn't be allowed to stop other websites from displaying the same information in unique maps and tables. And the online classifieds leader certainly can't claim that data points as crucial to commerce as prices, locations and basic descriptions can be copyrighted.

"Legal experts say presenting the entirety of listings in the same format as Craigslist would be troublesome, but that's not what PadMapper is doing. And a 1991 case dealing with phone books suggests that the bare-bones data in listings is not subject to copyright law, these experts say.
...
"Craigslist and its lawyers did not respond to requests for comment. In the lawsuit, Craigslist says that "the originality, simplicity, and clarity" of its website "are fundamental to Craigslist's reputation and garner substantial and valuable goodwill with users." 

Kidney donation and (loss of) medical insurance

Some things are so far off the equilibrium path that they drive me crazy: The Reward for Donating a Kidney: No Insurance

"Like most other kidney donors, Mr. Royer, a retired teacher in Eveleth, Minn., was carefully screened and is in good health. But Blue Cross and Blue Shield of Minnesota rejected his application for coverage last year, as well as his appeals, on the grounds that he has chronic kidney disease, even though many people live with one kidney and his nephrologist testified that his kidney is healthy. Mr. Royer was also unable to purchase life insurance."

File this under "negative compensation for donors."

Collusion, for fun and profit: Marshall and Marx

I was delighted to receive in the mail the new book The Economics of Collusion: Cartels and Bidding Rings, by Robert C. Marshall and Leslie M. Marx.

The book is devoted to the description and analysis of explicit collusion (their emphasis). I haven't read it yet, but one of the things that makes explicit collusion so entertaining to study and read about is that there are often detailed accounts (typically from court cases) about just how the collusion was accomplished.

Examples:
Marshall:  "Collusive Bidder Behavior at Single Object Second price and English Auctions," with D. Graham, Journal of Political Economy, 1987, 95, 1217-1239.

Circumcision: maybe not so repugnant after all

While a German court's ban on circumcision earlier this summer continues to be debated in Germany (where criminal charges have now been filed against a mohel--a religious circumciser), the American Academy of Pediatrics has issued a report saying that the health benefits of circumcision outweigh the risks, and that it should be covered by medical insurance.

Here's the NY Times story: Benefits of Circumcision Are Said to Outweigh Risks

"The American Academy of Pediatrics has shifted its stance on infant male circumcision, announcing on Monday that new research, including studies in Africa suggesting that the procedure may protect heterosexual men against H.I.V., indicated that the health benefits outweighed the risks.

"But the academy stopped short of recommending routine circumcision for all baby boys, saying the decision remains a family matter. The academy had previously taken a neutral position on circumcision.

"The new policy statement, the first update of the academy’s circumcision policy in over a decade, appears in the Aug. 27 issue of the journal Pediatrics. The group’s guidelines greatly influence pediatric care and decisions about coverage by insurers; in the new statement, the academy also said that circumcision should be covered by insurance.

"The long-delayed policy update comes as sentiment against circumcision is gaining strength in the United States and parts of Europe. Circumcision rates in the United States declined to 54.5 percent in 2009 from 62.7 percent in 1999, according to one federal estimate. Critics succeeded last year in placing a circumcision ban on the ballot in San Francisco, but a judge ruled against including the measure.

"In Europe, a government ethics committee in Germany last week overruled a court decision that removing a child’s foreskin was “grievous bodily harm” and therefore illegal. The country’s Professional Association of Pediatricians called the ethics committee ruling “a scandal.”

"A provincial official in Austria has told state-run hospitals in the region to stop performing circumcisions, and the Danish authorities have commissioned a report to investigate whether medical doctors are present during religious circumcision rituals as required.

"Officials with the Centers for Disease Control and Prevention in Atlanta, which for several years have been pondering circumcision recommendations of their own, have yet to weigh in and declined to comment on the academy’s new stance. Medicaid programs in several states have stopped paying for the routine circumcision of infants."
*********************

The American pediatricians are unlikely to have much impact on the debate in Europe, but their opinion might make it even harder for attempts to ban circumcision in the U.S., like the failed attempt in California.

Iraqi arranged marriages--the suicide constraint

The individual rationality constraint isn't very binding when individuals don't have good outside options, but it doesn't entirely go away. In Iraq, it's taking the form of suicide by unwilling brides in arranged marriages: Where Arranged Marriages Are Customary, Suicides Grow More Common

"In this desolate and tradition-bound community in the northwest corner of Iraq, at the foot of a mountain range bordering Syria, Ms. Merza’s reaction to the ancient custom of arranged marriage is becoming more common. Officials are alarmed by what they describe as a worsening epidemic of suicides, particularly among young women tormented by being forced to marry too young, to someone they do not love.

"While reliable statistics on anything are hard to come by in Iraq, officials say there have been as many as 50 suicides this year in this city of 350,000 — at least double the rate in the United States — compared with 80 all of last year. The most common methods among women are self-immolation and gunshots.

"Among the many explanations given, like poverty and madness, one is offered most frequently: access to the Internet and to satellite television, which came after the start of the war. This has given young women glimpses of a better life, unencumbered by the traditions that have constricted women for centuries to a life of obedience and child-rearing, one devoid of romance.
...

"Ms. Merza’s father, Barkat Hussein, interviewed later in private, said he was aware that the shooting was not an accident.

“We gave her to her cousin less than 20 days ago,” he said. “She accepted him. Like anyone who gets married, she should be happy.”

"He said he would not force her to return to her husband, who lives next door. But, he said: “I hope she will go back to him. His father is my brother.”

"He, too, blamed the Turkish soap opera for his daughter’s unhappiness, and he nodded toward the room where his wife was working. “I got married to my cousin,” he said. “I wasn’t in love with her, but we are here, living together. That’s what happens here, we marry our relatives.”

Regulating prostitution in New Zealand

An incentive issue (although they are not the focus of this story):
"But the Prostitutes Collective warned that outlawing popular streets would encourage sex workers to stop carrying condoms in case they are questioned by police."

Incentives and organ donation in Germany

Bettina Klaus writes:  There is an article about a recent organ donation scandal at the university hospital Goettingen. 

One of the transplant surgeons there seems to have manipulated patient files (25 cases are currently under investigation) in order to push his patients up on the waiting list. Interestingly his salary depended on the numbers of transplants he did and the article states that under his lead the number of liver transplants at the university hospital Goettingen had significantly increased in 2009 and 2010. 

Here's an English account of that, and organ sales as well: Desperation, Greed and the Global Organ Trade 
************

Something similar  to the Goettingen events led to a change in the deceased-donor liver allocation system in the U.S.
*******************************

See also http://www.spiegel.de/gesundheit/diagnose/organspende-skandal-goettingen-montgomery-fordert-schaerfere-kontrollen-a-847985.html, for a related story (also in German), which focuses on recent changes in the German transplant and organ donation systems. (HT Rosemarie Nagel)
************

And Markus Mobius points to this article (also in German, but the headline is clear): Transplantationsskandal

He writes "The article says that an increasing share of transplants in Germany are now bypassing the waiting list and go straight to in-house patients.
"10 years ago, 9.1% of livers, 8.4% of hearts, 10.6% of lungs and 6.3% of pancreas bypassed the waiting list. Now the shares are 37.1%, 25.8%, 30.3% and 43.7%, respectively. "

Assisted dying: still illegal, still controversial

The death yesterday of a British advocate for medically assisted death for terminally ill patients brings back the debate about whether physician assisted suicide should always be a repugnant transaction.

Here's the BBC's story: Right-to-die man Tony Nicklinson dead after refusing food

"Tony Nicklinson, a man with locked-in syndrome who fought for the right to legally end his life, has died.

"The 58-year-old was paralysed from the neck down after suffering a stroke in 2005 and described his life as a "living nightmare".

"Last week Mr Nicklinson, from Melksham, Wiltshire, lost his High Court case to allow doctors to end his life.

"Mr Nicklinson's family solicitor said that he had refused food from last week."
*************

Here's the NY Times: British Man Who Fought for Assisted Suicide Is Dead

"A 58-year-old British man suffering from so-called locked-in syndrome died on Wednesday, six days after the nation’s High Court rejected his request for help in ending his life. His death is certain to galvanize the already contentious debate about assisted suicide in Britain."
************

And here's an article about the controversy, in favor of a change in the laws against assisted suicice, published a few days earlier (it appears): The case for assisted dying

"The case for a law to legalise the choice of physician-assisted dying for mentally competent people with terminal illness, who have expressed a settled wish to die, is very easily stated. Unbearable suffering, prolonged by medical care, and inflicted on a dying patient against their will, is an unequivocal evil. What’s more, the right to have your choices supported by others, to determine your own best interest, when you are of sound mind, is sovereign. And this is accepted by a steady 80-plus per cent of the UK population in successive surveys.

"Even so, after decades of campaigning, the law has yet to change. How can this be? The answer is simple: there has been a highly organised opposition by individuals and groups, largely with strong religious beliefs that forbid assistance to die. "

Selective abortion based on gender: illegal in Britain but not in the U.S.

Two stories, the first from the Telegraph and the second from the Washington Post, reveal the different legal status of abortions for the purpose of choosing the gender of a child in Britain and the U.S.

Abortion investigation: doctors filmed agreeing illegal abortions 'no questions asked'. Women are being granted illegal abortions by doctors based on the sex of their unborn baby, an undercover investigation by The Daily Telegraph reveals.

"Doctors at British clinics have been secretly filmed agreeing to terminate foetuses purely because they are either male or female. Clinicians admitted they were prepared to falsify paperwork to arrange the abortions even though it is illegal to conduct such “sex-selection” procedures."

Bill banning ‘sex-selective abortions’ fails in the House

"A measure to ban abortions based on the sex of a child failed Thursday to earn enough support in the House, and abortion opponents said they plan to use the vote to paint Democrats as disingenuously supporting women’s rights because they voted against a bill protecting unborn baby girls.

Lawmakers voted 246 to 168 on the Prenatal Nondiscrimination Act (PRENDA), which would punish doctors with up to five years in prison for performing abortions because the parents are seeking a child of the other sex. But the bill failed to pass as House Republicans brought it up under a suspension of normal rules that required it to earn a two-thirds majority vote. Twenty Democratic lawmakers voted for the bill; seven Republicans voted against it.

...

"Several nations, including Canada, the United Kingdom, Germany and France, ban sex-selective abortions. The United States has no such law, even though the State Department has published reports critical of other countries, including China, for widely accepting the procedure.

Sex-selective abortions are so common in some Asian and Eastern European countries, including China, India, Armenia and Serbia, that the number of boys being born is much greater than the number of girls,according to the Guttmacher Institute, an abortion rights research center. In the U.S., 105 boys are born for every 100 girls, a ratio that the Center for Disease Control and Prevention considers stable. But limited studies have found that the practice is common among Asian American communities, where women cite family pressure to have male children.

Efforts to combat sex-selective abortions are more active at the state level. Eight states have introduced measures this year to ban the procedure, and three states — Arizona, Pennsylvania and Oklahoma — ban sex-selective abortions. A similar law in Illinois was scrapped by state courts.
