Q: Paragraph: Unions and professional groups for such employees say those jobs often are lower priority when budgets are tight, but their absence can have profound effects on student learning and teachers’ work. They contend support staff is vital to properly address everyday student issues such as physical and mental health problems or homelessness. In Chicago, the nation’s third-largest school district, the teachers who have been out on strike since last Thursday are seeking commitments for support staff hiring alongside other demands including higher pay and affordable housing citywide. The demands are part of the union’s “social justice” agenda. Bridget Nelson, a social sciences teacher at a magnet high school in Chicago, said her school is lucky to have a nurse most days but a social worker still is responsible for more than 2,000 students. “Adolescence is a challenging time, and we worry about depression and stress like a lot of educators,” Nelson said. “Some students have support at home, but others don’t. They should have support at school to help give them what they need.” The support-staff issue has come up elsewhere in spring protests by thousands of educators in North Carolina and South Carolina; in Minnesota, where a state survey recently found an increase in students’ mental and emotional health concerns; and in strikes in California, where teachers won promises for hundreds of additional nurses and more counselors in Los Angeles schools and more psychologists and special education instructors in Oakland. Shortages are causing problems in schools across the country, said Melissa Cropper, president of the Ohio Federation of Teachers. While discussing labor unions on a visit this month to a government class in an urban Ohio high school, Cropper said she asked the students what they would want prioritized in negotiations. A girl who had attempted suicide answered first: a counselor. Another student wanted a nurse. “We’ve got kids who are dealing with thinking about committing suicide or coming to school hungry or watched a domestic abuse situation over the weekend,” Cropper said. “We can’t possibly begin to think that we’re going to teach them something that’s going to stick with them until we’ve dealt with these other issues.” Most teachers don’t have specific training to tackle those sorts of concerns, so they’re advocating for schools to add more colleagues who do, American Federation of Teachers President Randi Weingarten said. The American School Counselor Association recommends one counselor for every 250 students but has found the average ratio to be nearly double that. The National School Nurses Association’s most recent estimates, from a study published early last year, indicated less than 40% of schools had a full-time nurse and about a quarter didn’t employ one at all. In those cases, teachers may have to assess and address issues such as gym class injuries, and preventive care can dwindle, said Donna Mazyck, the executive director of the nurses association. At John Tartan Elementary School in North Las Vegas, an assistant trained in basic first aid often handles minor injuries and distributes basic medications because the nurse splits duty at multiple schools, said Marie Neisess, a veteran teacher and reading specialist there. The school of 400-plus students also has a counselor, a social worker and a psychologist, but they struggle to keep up with the needs of the student body, which includes children facing challenges such as severe behavioral problems, foster care or a parent’s incarceration, she said. “We’re all kind of putting Band-Aids on the very big problem that we have here,” Neisess said. In Chicago, Mayor Lori Lightfoot had campaigned with an education plan that included staffing schools with full-time nurses, social workers and librarians, and enabling students to get mental health services. The district has committed to hiring more nurses, social workers and support staff but objected to making that part of the teachers’ contract. The union also has expressed concern about the various roles counselors are expected to fill, including as substitute teachers and lunchroom help, and asked for contract language that spells out that people will only be asked to do the jobs for which they are hired. Pushing for something enforceable in writing makes sense to Matt Mandel, a middle-school English teacher in the Philadelphia School District, who said the local union there has fought to have a nurse and counselor at each school. “In these urban districts like Philadelphia and Chicago, our kids need more,” Mandel said, “and we always find ways to justify giving them less.” ___ Associated Press reporter Kathleen Foody in Chicago contributed to this report. Claim: Chicago teachers’ strike highlights support staff shortages.

A: Demands by striking Chicago teachers for more nurses, librarians and social workers are highlighting concerns that resonate in high-poverty school districts nationwide, where shortages of support staff leave educators feeling stretched.

Q: Paragraph: HIIT can blast calories, build muscle and boost endurance with impressive efficiency in just 20 minutes a day, but the catch is finding the right level of intensity outside the comfort zone, fitness trainers say. Sean Bartram, author of the book “High Intensity Interval Training for Women,” said to find that level people should think about what it is like being chased by a rabid dog. “It’s just below that,” he said. “To gain maximum benefits you have to push your body to a place that’s almost uncomfortable.”   The American College of Sports Medicine predicts HIIT will be a top fitness trend in 2015. Bartram said people are drawn to it for its efficiency and almost endless variety of exercises. The bursts can be sprinting or spot jumps and the recovery can be rests or slower paced movements, he explained. “You could alternate 30 seconds of sprinting with 30 seconds of walking, or you could engage in a series of bodyweight exercises, such as push-ups, doing each for 30 seconds with 10 seconds of rest in between,” he said. Dr. Michele Olson, a professor of exercise science at Auburn University at Montgomery, Alabama, said it’s not high intensity unless the heart rate is elevated to near 90-plus percentage of its maximum. “Many people think they are engaging in HIIT but they are really doing traditional interval training, where the heart rate is around 75 to 85 percent of max,” she said. Maximum heart rate is about 220 minus age, according to the American Heart Association. Olson said that if done properly, HIIT can increase the effectiveness in losing abdominal fat and prompt favorable changes in cholesterol and insulin levels. “There is research showing that you can cut your exercise time nearly in half,” she said. About 20 minutes of HIIT can reap similar benefits of doing 35 to 40 minutes of moderate, steady-state cardio, she added, noting the training level must be intense. Hayley Zawadzki, personal training manager at New York Health and Racquet Club fitness centers, suggests that anyone starting HIIT should have a fitness analysis. “If you have a history of high blood pressure or medications, you cannot push to the absolute max,” she said. Claim: Key to High Intensity Interval Training found outside comfort zone.

A: With High Intensity Interval Training (HIIT), which consists of short bursts of intensive activity followed by short periods of  recovery, fitness experts say the harder the push, the greater the reward.

Q: Paragraph: In 2007, nearly one-third of all births were Caesarean deliveries, the U.S. Centers for Disease Control and Prevention said in a report, noting large rises in all racial, ethnic and age groups over 10 years. The benefits and risks of Caesarean delivery, which involves major abdominal surgery, have been the subject of intense debate for more than a quarter of a century. In addition to health and safety risks for mothers and infants, hospital charges for a Caesarean delivery are almost double those for a vaginal delivery, according to the CDC. Caesarean delivery was the most frequently performed surgery in the United States in 2006, it said. After a drop in the early 1990s, the Caesarean rate rose from 21 percent of all births in 1996 to an all-time high of 32 percent in 2007, the report said. The number of Caesarean births rose 71 percent from 797,119 in 1996 to 1.367 million in 2007, it said. There was a big jump among women under the age of 25 beginning around 2000. Some of the increase may be related to a rise in multiple births and other non-medical factors such as older mothers, the mother’s choice and the doctor’s practice, the CDC said. Caesarean births rose in all states and the District of Columbia but the rates varied widely. Colorado, Connecticut, Florida, Nevada, Rhode Island and Washington had increases of more than 70 percent. Claim: Caesarean births hit record high in 2007.

A:
Nearly 1.4 million babies born in the United States in 2007 were delivered by Caesarean section, a record U.S. high and a larger number than in most other industrialized nations, health officials said on Tuesday.
