The Female Factor: Chinese Courts Turn a Blind Eye to Abuse

BEIJING — Before they married in 2009, Tan Yong admitted to Li Yan that he had beaten his three previous wives. He promised to change.

The promises didn’t last, said Li Dehuai, Ms. Li’s brother. Soon after the wedding, Mr. Tan began abusing his wife.

“He stubbed out cigarettes on her face and legs. He would take her hair and hit her head against the wall. He locked her on the balcony for hours in the winter,” said Mr. Li, speaking by telephone from Chongqing in southwestern China. The abuse went on for more than a year.

Today, Mr. Tan is dead, beaten to death by Ms. Li with the barrel of his air gun during an argument in November 2010, and Mr. Li is trying to save his sister’s life as she sits in a jail in Sichuan Province awaiting execution for murder. The case has caused an outcry among Chinese legal experts and feminists, who say it underscores the severe sentences often imposed on women who fight back, injuring or killing abusive husbands.

“Li Yan’s case tells people that extreme tragedy will happen if an abused woman cannot get effective help from the neighborhood committee, the women’s federation, the police,” said Feng Yuan, of the Anti-Domestic Violence Network, based in Beijing.

“When power cannot deliver justice, abused women will find their own way of achieving justice, sadly and wrongly,” Ms. Feng said.

Chinese law requires that a history of domestic abuse be considered in such cases. Ms. Li’s was especially gruesome: After killing her husband (which she confessed to early, asking a neighbor to call the police), she cut him up and boiled some of the parts. If that is hard to excuse, consider this, said Ms. Feng: She wasn’t in her right mind.

“There’s something called abused women’s syndrome, and she had it. A woman like that may lose her reason and lose control,” said Ms. Feng, one of hundreds of people petitioning the courts to retry Ms. Li, this time taking the abuse into proper consideration. This was not done the first time, making Ms. Li’s case a miscarriage of justice, they say.

Others who have joined the appeal include lawyers, deputies to the National People’s Congress and Amnesty International, which last week issued an urgent action call for the Chinese authorities not to execute Ms. Li. The sentence could be carried out any day now, activists say, probably before the Lunar New Year’s Eve on Feb. 9.

Women’s jails are filled with women who have injured or killed abusive husbands, according to the Anti-Domestic Violence Network, citing studies by local women’s federations and scholars. They account for 60 percent of inmates in one jail in Anshan, in Liaoning Province, and 80 percent of women serving heavy sentences in a jail in Fuzhou, in Fujian Province.

In a study by Xing Hongmei of China Women’s University, of 121 female inmates in a Sichuan jail who were serving time for attacking or killing abusive partners, 71 were originally sentenced to life in prison or to death (sometimes commuted, delayed or overturned on appeal), and 28 more were sentenced to at least 10 years. This means more than 80 percent received the heaviest possible sentences for murder or bodily harm, the study said.

For months before she killed Mr. Tan, Ms. Li sought help from the authorities in Anyue County, in Sichuan Province, where they lived, her brother said.

“She telephoned the police in, I think, May 2010, after a beating, but they said it was an affair between married people and hung up,” he said.

She went to her neighborhood committee. “They told her to go to the women’s association. The women’s association told her to go to the police. The police told her to go to the neighborhood committee,” and so it continued, he said. “She was sent from place to place and didn’t know what to do.”

Officials at the local justice department whom she asked about divorce told her that unless Mr. Tan agreed, she could be left destitute. She was better off tolerating the abuse, they advised.

There was some documentation of the abuse, including police photographs of injuries and a medical report after hospital treatment, said Mr. Li. But both the Sichuan court that sentenced her and the Supreme Court in Beijing, which reviews all death sentences — Mr. Li and activists say it upheld his sister’s sentence last week — failed to take this into account when sentencing her, Mr. Li said.

“We all hoped the court would recognize the torture she’d suffered in those years,” he said. “But it didn’t.”

“I know what my sister did was wrong, but since this happened, I have studied many cases of domestic abuse, and I know her situation is not uncommon,” he said.

He has not yet been able to tell their mother, or Ms. Li’s 18-year-old daughter from a previous marriage, that Ms. Li faces imminent execution.

“I think my niece knows, somehow,” he said. “But my mother couldn’t take it.”

Their father, who died last year, had worked in the same silk factory as Ms. Li and Mr. Tan, and had disliked the man from the start, Mr. Li said.

“He was so depressed at her situation,” he said. “I think he died of grief.”

DealBook: Beneath the Calm, SAC Works to Contain Fallout From Inquiry

At last month’s Hurricane Sandy benefit concert, Steven A. Cohen sat near the Madison Square Garden stage, grooving to performances by Bon Jovi and Billy Joel.

Last week, he flew a private jet to the World Economic Forum in Davos, Switzerland, rubbing shoulders with world leaders and Fortune 500 chieftains. And on Monday, he will show up at the Breakers Resort in Palm Beach, Fla., for one of the year’s biggest hedge fund conferences and, if he can squeeze it in, a round of golf.

For a man who has emerged as the Justice Department’s great white whale in its insider trading investigation — a Wall Street version of Captain Ahab pursuing Moby-Dick — Mr. Cohen, the billionaire owner of the hedge fund SAC Capital Advisors, does not appear concerned.

But inside the offices of SAC’s Stamford, Conn., headquarters, and at Midtown Manhattan law firms, Mr. Cohen’s employees and lawyers are working hard to contain the fallout from the investigation.

His executives have offered financial incentives to Mr. Cohen’s staff members to stay with SAC. Marketing officers are trying to persuade investors to keep their money at the fund. And defense lawyers are working furiously to persuade federal securities regulators not to file a civil fraud lawsuit against the firm.

“This has always been a stressful place to work,” said an SAC employee who requested anonymity because he was unauthorized to speak publicly about the fund. “Now it’s just more stressful.”

Neither SAC nor Mr. Cohen has been accused of any wrongdoing.

The main question now looming over the firm is whether its clients will stand by the fund, or its legal and regulatory problems will cause investors to head for the exits. Under the firm’s rules, SAC clients have until Feb. 15 to ask for their money back, and then cannot make another so-called redemption request for another three months.

Mr. Cohen’s fund was dealt a blow last week when a Citigroup unit that manages money for wealthy families disclosed that it was withdrawing its $187 million investment. The move by the bank was the most prominent client departure since November, when the multiyear investigation into SAC’s trading practices entered a more serious phase.

Citigroup’s withdrawal represents a tiny percentage of SAC’s $14 billion in assets under management. The fund has said it expects total investor redemptions for the first quarter of up to $1 billion, a number that an SAC spokesman has said will not adversely affect its business.

SAC is largely insulated from the potentially devastating effects that client defections can have on a hedge fund in part because of Mr. Cohen’s extraordinary wealth. Unlike other hedge fund managers who rely almost entirely on outside investors, Mr. Cohen has the comfort of knowing that about $8 billion of SAC’s fund belongs to him and his employees.

Still, the Citigroup decision stung, say people close to SAC’s business, because of the longstanding and lucrative relationship between the bank and the fund. Another concern, said these people, is that the move could influence other large SAC investors currently weighing whether to keep their money at the fund.

For Citigroup, its withdrawal of money from SAC carries substantial business risk. The bank has a vast relationship with SAC, earning revenue by providing the fund with financing and trading services.

SAC could exact retribution on Citigroup by terminating, or at least scaling back, its broader relationship with the bank. An SAC spokesman declined to comment.

Citigroup’s move came two months after federal authorities arrested Mathew Martoma, a former SAC portfolio manager, in what they described as the most lucrative insider trading case ever uncovered. The Martoma indictment represented the first time that the government had brought charges stemming from a trade in which Mr. Cohen had been involved. The Securities and Exchange Commission has warned Mr. Cohen that it might file a civil fraud action against SAC related to the case.

In addition to Mr. Martoma, at least seven former SAC employees have been tied to insider trading while at the fund. Three have pleaded guilty to criminal charges.

Citigroup issued a statement that its decision “should not be construed as a statement on the merits of any outstanding legal proceedings or potential regulatory action.” But the bank specifically cited the Martoma case, explaining that “in the event these legal and regulatory matters are resolved favorably for Mr. Martoma and SAC, Citi Private Bank expects to reconsider admission of SAC’s funds to its hedge fund platform.”

Mr. Martoma has pleaded not guilty and rejected requests by federal agents to cooperate against his former boss. Mr. Cohen has told his employees and clients that he is confident that he has acted appropriately at all times.

Yet the heightened government scrutiny has caused skittishness among SAC’s top ranks, forcing the fund to lavish even richer financial incentives on a group of employees that is already among the most highly compensated in the hedge fund industry.

This month, SAC told its stable of portfolio managers that it would increase year-end bonuses by three percentage points. SAC portfolio managers — the fund’s most senior traders, given the authority to make their own investment decisions and also feed Mr. Cohen their best ideas — are paid, on average, 20 percent of the profits they generate for the fund.

“The program is intended to retain our most valuable resource, our investment professionals,” said Jonathan Gasthalter, the SAC spokesman.

Another valuable resource is SAC’s outside investors, which account for about $6 billion, or 40 percent, of the fund’s assets. That money accounts for hundreds of millions of dollars in fees, which SAC uses to finance one of the world’s largest and most sophisticated hedge fund operations, with more than 1,000 employees and 125 teams of traders and analysts. Its operation is also one of the most successful, posting average annualized returns of about 30 percent since 1992.

Those results have in the past kept SAC’s customers satisfied, but the government scrutiny has made many of them uneasy. The firm’s marketing team has reached out to the fund’s investors to address their concerns and reassure them that the insider trading inquiry will not affect its performance.

Despite those efforts, several investors in addition to Citigroup, including Titan Advisors and a unit of Société Générale, have notified SAC that they are withdrawing money. Other clients, like Chapwood Investments and SkyBridge Capital, have said they will continue to invest with the fund.

SAC executives continued the charm offensive with major clients on Sunday, holding an annual golf outing in Palm Beach on the eve of a hedge fund conference at the Breakers sponsored by Morgan Stanley. The conference — a matchmaking event that connects top managers with the world’s richest investors — is considered an important stop on the hedge fund money-raising circuit.

Since Morgan Stanley does not invite the news media to its conference, there is not expected to be the same paparazzi-like reports on Mr. Cohen that emerged last week from Davos. Bloomberg News filed a dispatch that Mr. Cohen sat in on a panel discussion on data security called “The Digital Infrastructure Context.” And Henry Blodget, the editor of the financial Web site Business Insider, wrote a Twitter post on a sighting of Mr. Cohen.

“Steve Cohen was hanging in Davos lounge yesterday,” he wrote. “Didn’t look worried.”

Well: Keeping Blood Pressure in Check

Since the start of the 21st century, Americans have made great progress in controlling high blood pressure, though it remains a leading cause of heart attacks, strokes, congestive heart failure and kidney disease.

Now 48 percent of the more than 76 million adults with hypertension have it under control, up from 29 percent in 2000.

But that means more than half, including many receiving treatment, have blood pressure that remains too high to be healthy. (A normal blood pressure is lower than 120 over 80.) With a plethora of drugs available to normalize blood pressure, why are so many people still at increased risk of disease, disability and premature death? Hypertension experts offer a few common, and correctable, reasons:

¶ About 20 percent of affected adults don’t know they have high blood pressure, perhaps because they never or rarely see a doctor who checks their pressure.

¶ Of the 80 percent who are aware of their condition, some don’t appreciate how serious it can be and fail to get treated, even when their doctors say they should.

¶ Some who have been treated develop bothersome side effects, causing them to abandon therapy or to use it haphazardly.

¶ Many others do little to change lifestyle factors, like obesity, lack of exercise and a high-salt diet, that can make hypertension harder to control.

Dr. Samuel J. Mann, a hypertension specialist and professor of clinical medicine at Weill-Cornell Medical College, adds another factor that may be the most important. Of the 71 percent of people with hypertension who are currently being treated, too many are taking the wrong drugs or the wrong dosages of the right ones.

Dr. Mann, author of “Hypertension and You: Old Drugs, New Drugs, and the Right Drugs for Your High Blood Pressure,” says that doctors should take into account the underlying causes of each patient’s blood pressure problem and the side effects that may prompt patients to abandon therapy. He has found that when treatment is tailored to the individual, nearly all cases of high blood pressure can be brought and kept under control with available drugs.

Plus, he said in an interview, it can be done with minimal, if any, side effects and at a reasonable cost.

“For most people, no new drugs need to be developed,” Dr. Mann said. “What we need, in terms of medication, is already out there. We just need to use it better.”

But many doctors who are generalists do not understand the “intricacies and nuances” of the dozens of available medications to determine which is appropriate to a certain patient.

“Prescribing the same medication to patient after patient just does not cut it,” Dr. Mann wrote in his book.

The trick to prescribing the best treatment for each patient is to first determine which of three mechanisms, or combination of mechanisms, is responsible for a patient’s hypertension, he said.

¶ Salt-sensitive hypertension, more common in older people and African-Americans, responds well to diuretics and calcium channel blockers.

¶ Hypertension driven by the kidney hormone renin responds best to ACE inhibitors and angiotensin receptor blockers, as well as direct renin inhibitors and beta-blockers.

¶ Neurogenic hypertension is a product of the sympathetic nervous system and is best treated with beta-blockers, alpha-blockers and drugs like clonidine.

According to Dr. Mann, neurogenic hypertension results from repressed emotions. He has found that many patients with it suffered trauma early in life or abuse. They seem calm and content on the surface but continually suppress their distress, he said.

One of Dr. Mann’s patients had had high blood pressure since her late 20s that remained well-controlled by the three drugs her family doctor prescribed. Then in her 40s, periodic checks showed it was often too high. When taking more of the prescribed medication did not result in lasting control, she sought Dr. Mann’s help.

After a thorough work-up, he said she had a textbook case of neurogenic hypertension, was taking too much medication and needed different drugs. Her condition soon became far better managed, with side effects she could easily tolerate, and she no longer feared she would die young of a heart attack or stroke.

But most patients should not have to consult a specialist. They can be well-treated by an internist or family physician who approaches the condition systematically, Dr. Mann said. Patients should be started on low doses of one or more drugs, including a diuretic; the dosage or number of drugs can be slowly increased as needed to achieve a normal pressure.

Specialists, he said, are most useful for treating the 10 percent to 15 percent of patients with so-called resistant hypertension that remains uncontrolled despite treatment with three drugs, including a diuretic, and for those whose treatment is effective but causing distressing side effects.

Hypertension sometimes fails to respond to routine care, he noted, because it results from an underlying medical problem that needs to be addressed.

“Some patients are on a lot of blood pressure drugs — four or five — who probably don’t need so many, and if they do, the question is why,” Dr. Mann said.

India Ink: One Delhi Gang Rape Suspect Ruled a Minor

NEW DELHI

The Indian Juvenile Justice Board ruled Monday that one suspect in the recent fatal gang rape of a young woman on a moving bus is officially a juvenile, which could result in a lenient sentence if he is found guilty of the crime.

The teenager, who school records show is 17 years old, could receive a maximum sentence of three years in a detention facility if found guilty. Five other men accused of the premeditated rape and killing of a 23-year old physiotherapy student on Dec. 16 could face life imprisonment or the death penalty if found guilty.

The December gang rape and the victim’s subsequent death of injuries sustained during the rape prompted widespread protests in India over the lack of safety and justice for women, and calls for the rapists to be executed.

Some criminal and legal experts expected the juvenile to be forced to undergo a bone ossification test, which is sometimes used to determine age in India where birth records are not always accurate. But the juvenile board’s ruling Monday makes that unlikely.

J. Richard Hackman, an Expert in Team Dynamics, Dies at 72

J. Richard Hackman, a Harvard psychology professor whose fieldwork sometimes took him to the cockpit of an airliner to observe the crew in a nearly five-decade quest to determine the dynamics of teamwork and effective leadership, died on Jan. 8 in Boston. He was 72.

The cause was lung cancer, his wife, Judith Dozier Hackman, said.

Dr. Hackman, the author or co-author of 10 books on group dynamics, was the Edgar Pierce professor of social and organizational psychology at Harvard.

In one of his best-known books, “Leading Teams: Setting the Stage for Great Performances” (2002), he replaced the popular image of the powerful “I can do it all” team leader with that of someone who, as he wrote, had the subtle skills “to get a team established on a good trajectory, and then to make small adjustments along the way to help members succeed.”

The conditions for a successful team effort — among them “a compelling direction, an enabling team structure, a supportive organizational context and expert team coaching” — “are easy to remember,” Dr. Hackman wrote.

“The challenge,” he continued, “comes in developing an understanding of those conditions that is deep and nuanced enough to be useful in guiding action, and in devising strategies for creating them even in demanding or team-unfriendly organizational circumstances.”

Besides tracking the interplay of pilots, co-pilots and navigators aboard civilian and military planes, Dr. Hackman observed corporate boards, sports teams, orchestra players, telephone-line repair crews, hospital workers and restaurant kitchen staff members.

And in recent years, for his 2011 book, “Collaborative Intelligence,” he was allowed to observe interactions within the American intelligence, defense, law-enforcement and crisis-management communities.

“Although my main aspiration has been to provide guidance that will be useful to team leaders and members,” he wrote, “there are no ‘one-minute’ prescriptions here — creating, leading and serving on teams is not that simple.”

Anita Woolley, a professor of organizational behavior and theory at the Tepper School of Business at Carnegie Mellon University in Pittsburgh, said, “The key thing about Dr. Hackman’s work is that it stands in contrast to some of the more popular models of leadership that focused very much on style or how leaders behave, versus what they do.”

Rather than viewing pay as a prime motivator for good performance, she continued, “he focused on features of people’s jobs that made them more intrinsically satisfied: the freedom to determine how they conduct their work, having a variety of tasks, having knowledge of the ultimate outcomes of their work, knowing how their work affects or is received by other people.”

He also liked to overturn some of the received wisdom about teamwork. In a 2011 article for The Harvard Business Review, Dr. Hackman listed “Six Common Misperceptions About Teamwork.” Among them was this:

“Misperception No. 2: It’s good to mix it up. New members bring energy and fresh ideas to a team. Without them, members risk becoming complacent, inattentive to changes in the environment, and too forgiving of fellow members’ misbehavior.

“Actually: The longer members stay together as an intact group, the better they do. As unreasonable as this may seem, the research evidence is unambiguous. Whether it is a basketball team or a string quartet, teams that stay together longer play together better.”

John Richard Hackman was born in Joliet, Ill., on June 14, 1940, the only child of J. Edward and Helen Hackman. His father was an oil pipeline engineer, his mother a schoolteacher.

Dr. Hackman received a bachelor’s degree in mathematics from MacMurray College in Jacksonville, Ill., in 1962, and a doctorate in psychology from the University of Illinois in 1966. He soon joined the psychology and administrative sciences department faculties at Yale, where he taught until 1986, when he moved to the psychology and business departments at Harvard.

Besides his wife, who is an associate dean at Yale, he is survived by two daughters, Julia Beth Proffitt and Laura Dianne Codeanne, and four grandchildren.

After Dr. Hackman died, The Harvard Crimson wrote that for years he had “devoted countless hours to improving one team in particular — the Harvard women’s basketball squad, for which he volunteered as an honorary coach.”

Well: Ask Well: Squats for Aging Knees

You are already doing many things right, in terms of taking care of your aging knees. In particular, it sounds as if you are keeping your weight under control. Carrying extra pounds undoubtedly strains knees and contributes to pain and eventually arthritis.

You mention weight training, too, which is also valuable. Sturdy leg muscles, particularly those at the front and back of the thighs, stabilize the knee, says Joseph Hart, an assistant professor of kinesiology and certified athletic trainer at the University of Virginia, who often works with patients with knee pain.

An easy exercise to target those muscles is the squat. Although many of us have heard that squats harm knees, the exercise is actually “quite good for the knees, if you do the squats correctly,” Dr. Hart says. Simply stand with your legs shoulder-width apart and bend your legs until your thighs are almost, but not completely, parallel to the ground. Keep your upper body straight. Don’t bend forward, he says, since that movement can strain the knees. Try to complete 20 squats, using no weight at first. When that becomes easy, Dr. Hart suggests, hold a barbell with weights attached. Or simply clutch a full milk carton, which is my cheapskate’s squats routine.

Straight leg lifts are also useful for knee health. Sit on the floor with your back straight and one leg extended and the other bent toward your chest. In this position, lift the straight leg slightly off the ground and hold for 10 seconds. Repeat 10 to 20 times and then switch legs.

You can also find other exercises that target the knees in this video, “Increasing Knee Stability.”

Of course, before starting any exercise program, consult a physician, especially, Dr. Hart says, if your knees often ache, feel stiff or emit a strange, clicking noise, which could be symptoms of arthritis.

Digital Domain: Republic Wireless’s Plan Melds Wi-Fi and Network Calling

AN Android smartphone with unlimited calls, unlimited texting, unlimited data and no contract, all for $19 a month? Really?

When I first saw this offer from Republic Wireless, I rubbed my eyes and looked for an asterisk leading to fine print that detailed a huge catch. But Republic, a division of a telecom company called Bandwidth.com, delivers exactly what it advertises. It can do so because the handset technology is a curious hybrid: it uses Wi-Fi when the customer is in a Wi-Fi area and Sprint Nextel’s 3G network when it is not.

The concept brings together the best of two worlds: the low cost of voice calls carried over the Internet and the convenience of making calls to any phone number using a major carrier’s cellular network when Wi-Fi isn’t available.

In my own case, on a typical day, I use my mobile phone mostly when I’m not actually mobile: I’m either at home or at work, perfectly positioned to use Wi-Fi at both locations. And I don’t even use the phone as a phone all that much. I use it mainly for e-mail and texts, neither of which requires enough bandwidth to benefit from the power of the fastest data networks.

If you walk into a Verizon Wireless store and buy an iPhone 5, you’ll pay $60 or more a month for an unlimited talk and texting plan, depending on the data allocation for Internet use that you select to go with it. Some of that monthly charge goes toward repaying the carrier for the discounted price that makes a $649 iPhone seem as if it costs only $200. But most of the charge is for gaining access to the carrier’s wireless network.

“We were looking at a mobile industry that had begun to charge extraordinary amounts of money, and we saw an industry opportunity that everybody else was missing: Wi-Fi is the new mobile,” says David Morken, co-founder and chief executive of Bandwidth, based in Raleigh, N.C.

Smartphone apps that offer voice calls using data plans, not minutes allocated for calls, are plentiful. Just last month, Facebook quietly added an option that lets users of the iPhone version of Facebook Messenger place free voice calls to other Messenger users. But using those apps to make a call means the recipient has to run the same app, an irksome requirement that never comes up when using phones alone.

Republic buys access to Sprint’s network on a wholesale basis for calls made outside of Wi-Fi areas. Its business model assumes, however, that Wi-Fi carries the load a majority of the time its phones are used. The company says that its service, even at $19 a month, is a profitable operation on a per-customer basis.

“We don’t have to force people, or even ask people, how to behave,” Mr. Morken says. “Over 60 percent of the time that the phone is being used, on average, our users are using Wi-Fi and that number is only going up.”

Last month, I tested a Republic handset, a Motorola Defy XT. It’s a light smartphone with a small screen, acceptable sound quality and great battery life.

Republic’s Web site gently warns against acting like a “data hog” and encourages its customers to “play nice and try to use Wi-Fi as much as you can.” But scolding isn’t needed: Wi-Fi is faster than 3G, so users have an incentive to opt for Wi-Fi wherever it is available.

The Motorola handset is the only one now offered by Republic, and it costs $259. The phone runs an older version of Android, and it has some first-generation glitches, like losing a connection when a caller starts out on a Wi-Fi network and then leaves the coverage area. (With a click, the call is resumed using Sprint’s cellular network.)

Today most Wi-Fi access requires a logon. But that shouldn’t prove a great inconvenience: you can simply set up the phone once with Wi-Fi at home, then once more at the office. At other locations, users can ignore Wi-Fi availability and use 3G instead.

Mr. Morken says a solution to the Wi-Fi-to-cellular handoff problem has been worked out in the company’s lab, and should be available midyear. Later this year, he also expects to offer more handset models, including one at the high end; he says they will run the latest version of Android.

Matt Carter, president of the Global Wholesale and Emerging Solutions division at Sprint, asserted that the company was happy to serve as Republic’s supplier. When I asked whether Republic’s Wi-Fi-centric model, with its drastically lower price to the consumer, would pose a serious threat to the incumbent carriers, including Sprint, he said, “If the world operated based on just economic decisions, people wouldn’t go buy the most expensive cars on the planet, right?”

Mr. Carter listed reasons that most consumers would prefer the wireless service obtained directly from a major carrier: a wider range of devices and the convenience of placing a call without having to tinker with Wi-Fi setup.

Republic “will resonate with a sliver of the marketplace,” Mr. Carter said. He compared wireless carriers to the major airline carriers, which still control a majority of the market despite low-priced upstarts like JetBlue or Southwest, which he described as appealing only to “a certain segment of the population.”

Philip Cusick, a J.P. Morgan analyst who covers telecommunications, says he doesn’t expect a major shift of customers to Republic Wireless. The price difference isn’t as great as it first appears, he says, when one considers that 80 percent of customers of AT&T and Verizon are on family or employer-related discount plans.

MR. MORKEN of Bandwidth.com says he knows that his company must lower the price of its handset — the industry rule-of-thumb for no-contract wireless services is that a simple handset cannot cost more than $99 and a smartphone, $149. But if Republic can offer me an Android phone with a generously sized screen for a reasonable price, I don’t see why, with Wi-Fi available at work and home, I should continue to pay an expensive-sports-car price for my wireless service.

“There’s a reason why the carriers around the world don’t want you using Wi-Fi for voice and text,” Mr. Morken says. “You will soon realize you shouldn’t have to pay what you’re paying today.”
