Nostalgia（怀旧） is a powerful emotion that can be employed to create a strong emotional connection between a brand and its audience. By tapping into the fond memories and positive associations that people have with a particular brand, marketers can create a sense of familiarity and comfort that resonates（共鸣） with their audience. This emotional connection can then be used to drive engagement and loyalty, ultimately leading to increased sales.

In the case of Barbie movie marketing, nostalgia has been used. By incorporating elements of the classic Barbie brand into the movies, such as the symbolic pink color, the classic Barbie logo, and the inclusion of classic Barbie characters, the movies serve as a way to transport fans back to their childhood and relive their favorite memories.

This emotional connection is further strengthened by the marketing campaigns, which create a sense of community and excitement around the brand. By using social media to build hype（夸张报道） and anticipation for each movie, the brand has managed to create a loyal and engaged fan base that has contributed to its success.

The success of Barbie movie marketing has not been limited to the brand's existing fan base. In fact, the movies have managed to attract a new generation of fans who may not have been familiar with the classic Barbie brand. By creating movies that are both entertaining and empowering, the brand has managed to appeal to a wider audience, including young girls who may be looking for strong female role models.

The impact of Barbie movie marketing on a new generation can be seen in the way that the brand has developed over the years. Although Barbie was once denounced for promoting unrealistic beauty standards and conventional gender images, the brand has since made significant steps in promoting diversity and inclusivity（包容性）. The recent Barbie movies feature diverse actors and storylines that promote self-empowerment and self-acceptance, reflecting the changing attitudes and values of society.

We've all done it before-dropped a box of unwanted household belongings at a flea market and driven off with a sense of accomplishment. But have you ever stopped to think about where those items actually go?

Business journalist Adam Minter began considering this while cleaning out his late mother's home. Seeking reassurance that his mother's donated items would be put to good use rather than destroyed, he started a journey worldwide that resulted in his latest book, "Secondhand: Travels in the New Global Garage Sale". He found the industry significantly in the dark, with a disturbing lack of data on secondhand goods, despite their crucial role in clothing, furnishing and educating people worldwide. 

In this book, Minter fully reveals himself as an investigative journalist. He doesn't shy away from the commonly-accepted assumptions about the global trade in used goods. First, Minter questions the idea that shipments of secondhand clothes from developed countries to Africa have destroyed local textile industries （纺织业）. That's overly simplistic, he says. He further explains that multiple factors, such as declining cotton production in local areas and economic liberation, have influenced the situation. 

Minter then explores the topic of car seats, making a statement that recycling car seats, instead of selling them secondhand, is wasteful and might compromise （危害） safety for children in developing countries. It is disturbing to say so in a society that prioritizes child safety and highlights zero risk, but when you consider the excessive caution that might endanger children's lives elsewhere, the situation starts to look different. 

Minter calls it "waste colonialism," this idea that developed countries can apply their own safety standards onto the markets of developing countries-and it's deeply wrong. Why label an used car seat or an old TV as unsafe if someone else, with different skills, is perfectly capable of repairing it and willing to use it, especially if they lack access to new products and other options?

The book explores the huge problems of handling surplus （剩余的） items and how producers discourage repairs and promote the sales of new products. Minter calls for initiatives to enhance product repairability and increase product lifetime. 

Saving Us: A Climate Scientist's Case for Hope and Healing in a Divided World is one of the most important books about climate change to have been written. Hayhoe is a gifted public speaker and Saving Us is a follow-up to her awesome TED talk in 2018, "The most important thing you can do to fight climate change: talk about it."

One of the many refreshing aspects of this book is that Hayhoe recounts both her successes and her failures to communicate, through which she has gathered evidence about what works and what does not. Much of the book's advice is common sense, all backed up not just by Hayhoe's experience but also with convincing research by psychologists and social scientists.

Hayhoe advises against trying to engage with a small minority, the "Dismissives", who "angrily reject the idea that human-caused climate change is a threat; they are most receptive to misinformation and conspiracy theories (阴谋论)". There is a warning that offering up more facts about climate change can actually increase polarisation (两极化) among them.

The book includes amusing examples of her encounters with the "Dismissives", almost entirely older men—including an engineer who was unconvinced about the evidence but with whom she was able to establish mutual (相互的) respect through a shared passion for knitting (打毛线衣) —and is packed with inspiring accounts of how she has won over even the most suspicious of crowds. Her motto is "bond, connect and inspire", which represents her approach of always looking for points of commonality.

She also tells of a man who approached her after an event in London in 2019. He had been so inspired by her TED talk that he had started to speak to everybody he could in his neighborhood of Wandsworth. He showed her details of 12, 000 conversations that had taken place as a result, claiming that they had helped to convince the government to declare a climate emergency and to switch investments from fossil fuels to renewable energy. 

And so, while it may feel difficult to influence the outcome of the COP26, Hayhoe's uplifting book makes a persuasive case that we can all do our bit to bring about success just by talking about the issue.
