In the last decade, global trends and social media have covered almost the entire world, including children population. The toy industry is filled with new items whose popularity has been triggered ...by viral publications on social networks or by popular animated films. The present experimental study is the first to (i) describe the characteristics of toy choice in the context of the spread of global trends, and (ii) examine the influence of family and individual child characteristics on the dependence on trends in toy choice. The sample consisted of
= 127 children aged 3-4 years. Children had individual assessment of non-verbal intelligence main executive function skills (cognitive flexibility, working memory and inhibition control) and took part in the experiment, while their parents completed a questionnaire on family background. Analysis of children's answers about the reason for choosing a particular toy indicates uncertain motivation in choosing a trendy toy in contrast to the classic ones. It is reflected in the fact that children do not know what exactly and how they will play with it. It is revealed that boys are 1.66 times more likely to prefer the trendy toy than girls. It was also found that as inhibitory control increased, children were less dependent on tendencies to choose toys.
From sushi and karaoke to martial arts and technoware, the currency of made-in-Japan cultural goods has skyrocketed in the global marketplace during the past decade. The globalization of Japanese ..."cool" is led by youth products: video games, manga (comic books), anime (animation), and cute characters that have fostered kid crazes from Hong Kong to Canada. Examining the crossover traffic between Japan and the United States,Millennial Monstersexplores the global popularity of Japanese youth goods today while it questions the make-up of the fantasies and the capitalistic conditions of the play involved. Arguing that part of the appeal of such dream worlds is the polymorphous perversity with which they scramble identity and character, the author traces the postindustrial milieux from which such fantasies have arisen in postwar Japan and been popularly received in the United States.
A nontargeted broad-spectrum analysis method for unknown volatile and semivolatile substances in toys was established by gas chromatography–Orbitrap high-resolution mass spectrometry. Based on the ...NIST spectrum library, unknown substances could be accurately identified by comprehensive scoring, retention index, chemical ionization, and fine comparison of ion fragments. For substances not included in the library, the molecular formulas of unknown substances were retrieved through online compound databases. Possible structural formulas were verified by high-resolution spectra and fragmentation mechanisms. Taking teether toys as an example, the substances differences of products made of different materials were compared through the digitization of chemical composition. Specifically, 59 substances were identified in 50 teether toys. The toys made of two different materials each had their own substance distribution, and the types and quantities of substances in thermoplastic polyurethanes samples were more than those in silicone samples. Substances with high risk included phenol, N-methylaniline, cyclohexanone, and 4-tert-amylphenol. This work can serve as a reference for the identification of unknown substances in toys and other products, as well as for the comparison the chemical composition of products made of different materials. Thus, this work has positive significance in promoting the quality and safety of toys and reducing chemical harm to children.
