"Relinquished" is an industry term used to describe the process where parents give up their children for adoption. The term is also the title of author Gretchen Sisson's new book, “Relinquished: The Politics of Adoption and The Privilege of American Motherhood” which profiles the stories of birth mothers and breaks down the myths and misunderstandings about the American adoption process.For many birth mothers, the stigma prevents them from forming healthy relationships with their child and the child's adoptive family said Sisson in an interview on Under the Radar with Callie Crossley. “When you only have these two types of stories to tell, the one where the [birth] mother doesn’t care, or the one where her desire to be part of her child's life is a problem, then you're not making space for openness in adoption that is well supported, well understood, and ultimately child-centered.”Listen to the full conversation above.GUESTGretchen Sisson, qualitative sociologist in the department of obstetrics, gynecology, and reproductive sciences at the University of California, San Francisco and author of "Relinquished: The Politics of Adoption and The Privilege of American Motherhood"

March Madness wraps up this week as top college basketball players compete for the coveted NCAA championship. Some of the most talented collegiate players will go on to join the pros in the NBA — and while it's likely they want to play like superstars LeBron James, Jason Tatum and Stephen Curry, to name a few, more and more it appears they also want to dress like them. "There was a lot of resistance at first," Mitchell S. Jackson, author of "Fly: The Big Book of Basketball Fashion" told Under the Radar. "And we're really talking about the youngsters that come in the league at that time, which is Dwayne Wade, LeBron James, Chris Bosh, Chris Paul. Those are the guys that started to embrace the new standards, or mandates, of the NBA Fashion." Under the Radar speaks with Jackson to learn how fashion icons have emerged from an unlikely setting — the NBA. GUEST Mitchell S. Jackson, Distinguished Professor in the Department of English at Arizona State University and author of "Fly: The Big Book of Basketball Fashion."

The COVID-19 pandemic exacerbated the national hunger crisis across the country. In Massachusetts, the number of households struggling with food insecurity more than doubled, from about 8% pre-COVID to a record high of 19% during the pandemic. Emergency food access programs, food pantries and even targeted pandemic food subsidies did not eliminate the hunger emergency. That inspired some communities across the state to install community refrigerators, filled with food shared by neighbors and local businesses. Maria Ravelli, of Woo Fridge and organizer behind the first-ever Worcester community fridge, shares that she is, "fueled by equal parts love and rage" to continue creating neighborly food-sharing spaces. Since the pandemic, these fridges have continued to serve the high demand of the community. "We do multiple checks a day to make sure that the fridge is clean, that it's as stocked as it can be," Megan Ramette, an organizer of the Allston-Brighton fridge, said. "Things that we see that are stocked in the morning often don't last through the afternoon, and they certainly don't last through the evening." GUESTS Megan Ramette, organizer for the Allston-Brighton community fridges. Maria Ravelli, organizer of Woo Fridge, from Worcester, Mass.

From immigration to reproductive rights, issues that ignited the country in the last presidential election will be re-litigated in the rematch between President Biden and former President Trump. As the contest heats up, former President Trump’s speeches are reaching new levels of violent rhetoric — at a recent rally he predicted a "blood bath" should he lose. And Gov. Maura Healey opposes a potential ballot question that would eliminate the MCAS test as a requirement for high school graduation, an opposition that puts her at odds with the Massachusetts Teachers Union backing the question. Plus, what are the takeaways from Super Tuesday and recent primary elections that may indicate trouble or triumph for both parties heading to November? That and more during Under the Radar with Callie Crossley's full hour with members of the Mass Politics Profs. GUESTS Erin O’Brien, associate professor of political science at the University of Massachusetts Boston Jerold Duquette, professor of political science and director of the Public Policy and Management Program at Central Connecticut State University Maurice Cunningham, former associate professor of political science at UMass Boston

How did Ella Fitzgerald become the legend she was? That’s the question author Judith Tick asks and answers in her new biography on the famed vocalist, “Becoming Ella Fitzgerald: The Jazz Singer Who Transformed American Song," our March selection for Bookmarked: The Under the Radar Book Club. Jazz and history buffs know about the young Ella Fitzgerald’s first nervous performance at Harlem’s famed Apollo Theater. The new book marks that pivotal moment in the life of the would-be dancer and many new details in the first full-scaled biography since the singer’s death nearly thirty years ago. Tick describes Fitzgerald's legacy as a duality: "She could sing all kinds of songs... she could go on all kinds of television programs and uplift people around her. And yet, at the same time, her humility and her ordinariness shows us the full dimensions of a great personality." From turning a nursery rhyme into a classic jazz tune to perfecting improvisational singing known as scatting, Ella Fitzgerald’s talent led her to become one of America’s cultural icons. GUEST Judith Tick, Professor emeritus of music history at Boston’s Northeastern University. She is the author of “Becoming Ella Fitzgerald: The Jazz Singer Who Transformed American Song.”

President Joe Biden and former President Donald Trump have officially clinched the required delegates for their Democratic and Republican presidential nominations. With the unofficial general campaign underway, both parties are eager to win the Latino vote. Now, a Republican strategy to shore up Latino support is becoming clear as they are aligning with Latin American politicians — far-right populist President of Argentina, Javier Milei, was a featured speaker at the recent Conservative Political Action Committee, as well as President of El Salvador, Nayib Bukele, who told the crowd to "put up a fight" against the "global elites" to win back the U.S. Plus, accusations of racism are flaring up as temporary shelters are being set up across the state to house migrant families. And Big Papi threw a first pitch at the Red Sox's recent exhibition game in the Dominican Republic — showcasing Dominican players’ dominance in American baseball. We break down those stories and more on our Latinx News Roundtable this week on Under the Radar with Callie Crossley. GUESTS Julio Ricardo Varela, MSNBC columnist and founder of Latino Rebels Marcela García, opinion columnist and associate editor at the Boston Globe

Greater Boston is home to one of the largest populations of Puerto Ricans. It's a local community that expanded by the thousands after World War II, when about six million islanders from the US territory made their way to the mainland looking for better economic opportunities. They enriched the nation’s cultural melting pot with aspects of indigenous customs and traditions. Today, with an even greater appreciation for authentic representation and a ready audience to celebrate it, organizers have created BoriCorridor, an inaugural arts-led tour of the Northeast to celebrate Boricuan, or Puerto Rican, diaspora heritage. Under the Radar gets a preview before it arrives in Boston later this month. GUESTS Elsa Mosquera, Co-Founder and Principal at the Agora Cultural Architects And Creator of BoriCorridor. Melissa Rodriguez, a stand-up comedian of Teatro Breve, the Puerto Rican variety show performing on the first weekend of the BoriCorridor tour.
