‘Always pass the salt and pepper together, even if your fellow diner has asked just for one of them’. That’s the standard advice given by countless dining etiquette manuals, one of the many rules regarding proper manners that have been handed down from generation to generation. But what if some of the rules have become outdated, silly or just wrong? And why do we have etiquette in the first place? Where do the rules of polite conduct come from and are they the same the world over? Iszi Lawrence follows the story of etiquette across time and over several continents with the help of Annick Paternoster, Lecturer at the University of Lugano in Switzerland who has a special interest in the history of politeness; Professor Daniel Kadar from Dalian University of Foreign Languages in China, the HUN-REN Hungarian Research Centre for Linguistics, and the University of Maribor in Slovenia; Courtney Traub, author and editor of the travel website Paris Unlocked; Japanese writer and cultural commentator Manami Okazaki; former Chief of Protocol at the Foreign Ministry of Grenada Alice Thomas-Roberts; and Forum listeners from around the world.(Photo: Business people shake hands.

In the 1990s, an advert for a brand of chocolate depicted a sophisticated gathering hosted by the foreign ambassador of an unspecified country. It hinted at a gilded existence of cocktail parties and small talk among influential, wealthy guests.

The humble plastic bag is actually a marvel of engineering: it is cheap, light, strong, waterproof and it has conquered the world. In countries where plastic bags have been banned, they are still being smuggled in. The environmental pollution and other problems that discarded plastic can cause has made it a focus of passionate debate. But is plastic really the problem or is it our increasing use of disposable and single-use items? The popularity of disposable products predates the invention of the plastic bag in the 1960s or even the advent of Western consumer society in the aftermath of the Second World War. And in the last three decades, so many new single-use items have been produced that we increasingly cannot imagine our lives without them, and not just in the festive season. So what is the way forward?Iszi Lawrence talks about all manner of disposable and single-use objects with Jennifer Argo, Professor of Marketing at the School of Business, Alberta University; Mark Miodownik, Professor of Materials & Society at University College London; Katherine Grier, Professor Emerita of History at the University of Delaware and founder of the online Museum of Disposability; space archaeologist Dr. Alice Gorman from Flinders University in Australia and listeners from around the world.(Photo: Digital image of plastic waste and a city skyline.

Political parties come in all shapes and sizes and their ideas are just as varied. But what kind of parties best reflect 21st-century society? How do we, as voters, choose between them at elections? What are their ever-increasing expenses spent on? And - perhaps most importantly - how well do political parties respond to the needs and views of the public?Iszi Lawrence discusses these questions with Professor Leonie Huddy from Stony Brook University who studies the psychology of politics, Associate Professor Karina Kosiara-Pedersen who researches party membership at the University of Copenhagen, Professor Paula Muñoz Chirinos who works on political finance at the University of the Pacific in Peru, Catherine Mayer co-founder of the Women's Equality Party in the UK, as well as student Luke Louis Ow from Singapore and other listeners from around the globe.(Photo: A sign in Dublin directing voters where to go in 2021.

We can probably all think of examples of bad bosses – the people who we love to gossip about with our colleagues outside work. And even if you’re lucky enough to have had good experiences of management, you may be familiar with bad bosses from popular culture. But what makes a good manager and how can you inspire people in the workplace? It’s a question that’s been debated since the Industrial Revolution when rapidly expanding companies needed a way of controlling their workers. From there developed various theories of management, some of which drew on aspects of sociology and psychology.Rajan Datar is joined by Ann Francke, the chief executive of the Chartered Management Institute in the UK; Monica Musonda, the CEO of Java Foods in Zambia; and Todd Bridgman, Professor of Management Studies and Head of the School of Management at Victoria University of Wellington / Te Herenga Waka in New Zealand.

In some ways the 21st century is a very unusual time when it comes to adolescence - a study in the US found that teenagers smoke less, drink less and have less sex than the previous generation. And worldwide young people are coming of age in a digital era, with the dangers and opportunities that represents. Our expectations of teenagers vary hugely depending on the social, historical and cultural context. Paleoanthropologist Ella Al-Shamahi takes us through the big evolutionary questions about adolescence: Why do humans go through this developmental stage? What's the point of all that teenage angst?

From Bhutan to The Bahamas and Iceland to Indonesia, mass tourism has grown at an unprecedented rate over the last few decades. Today’s top destinations are struggling with the sheer numbers of visitors and the United Nations has called for a total rethink on how the industry operates. The origins of travel for pleasure go back centuries and package holidays in the 1960s made it accessible to many in the West but it’s only the combination of cheap flights and the advent of the internet that has led to truly global tourism on a mass scale. Whilst the industry now generates huge income for many companies and individuals around the globe, critics point to the cost to both the environment and humankind. Drawing on listeners’ questions and comments, Rajan Datar examines the way mass tourism has impacted people’s lives, both positively and negatively, and asks if the enforced pause in tourism caused by Covid was utilised as an opportunity for a re-think. He is joined by Sihle Khumalo, a popular South African travel writer; Shazia Mirza, a renowned British comedienne and writer; Qupanuk Olsen, originally a mining engineer but now Greenland’s leading travel influencer; Prof. Noel Salazar, anthropologist of tourism from KU Leuven in Belgium; Iñigo Sánchez-Fuarros, senior researcher at the Institute of Heritage Sciences of the Spanish National Research Council and Dr. Birgit Trauer, tourism consultant and educator from Australia.[Photo: El Postiguet Beach in Alicante, Spain in the summer of 2022.
