France to trial ban on mobile phones at school for children under 15


Kim Willsher - Paris
Tue 27 Aug 2024


France is to trial a ban on mobile phones at school pupils who are younger than 15, seeking to give children a "digital pause" that, if judged successful, could be rolled out nationwide from January.

Just under 200 secondary schools will take place in the experiment that will require youngsters to hand over phones on arrival at reception. It takes the prohibition on the devices further than a 2018 law that banned pupils at primary and secondary schools from using their phones on the premises but allowed them to keep possession of them.

Announcing the trial on Tuesday, the acting education minister, Nicole Belloubet, said the aim was to give youngsters a "digital pause". If the trial proves successful, the ban would be introduced in all schools from January, Belloubet said.

A commission set up by the president, Emmanuel Macron, expressed concern that the overexposure of children to screens was having a detrimental effect on their health and development. 

A 140-page report published in March concluded there was "a very clear consensus on the direct and indirect negative effects of digital devices on sleep, on being sedentary - a lack of physical activity and the risk of being overweight and even obese - as well as on sight". It said the "hyper" use of phones and other digital technology was not only bad for children but also for "society and civilisation".

The report recommended children's use of mobile phones be controlled in stages: no mobile phones before the age of at least 11, mobiles without internet access between 11 and 13, phones with internet but no access to social media before 15.

It also suggested children under three years old should not be exposed at all to digital devices, which it said were "not necessary for the healthy development of the child".

"We must put the digital tool in its place. Up to at least six years old a child has no need for a digital device to develop," Servane Mouton, a neurologist and neurophysiologist who was on the commission, said. "We have to teach parents once again how to play with their children." 

Banning phones in schools has long been debated across Europe. In countries where bans exist this is most often confined to their use and do not require children to hand them over.

In Germany there are no formal restrictions but most schools have prohibited the use of mobile phones and digital devices in classrooms except for education purposes. A quasi ban has been in place in Dutch secondary school classrooms since the beginning of this year, but as a recommendation and not a legal obligation. From this school year the directive will also apply to primary schools.

Italy was early to phone bans, introducing one in 2007, easing it in 2017 and reimposing it in 2022. It applies to all age groups.

In February this year, the British government issued guidance for schools "on prohibiting the use of mobile phones throughout the school day" but said it was for individual head teachers and leaders to decide on phone use policy.

Portugal is experimenting with a compromise by introducing a number of phone-free days at schools each month, while in Spain schools in some autonomous regions have imposed a ban but there is no nationwide prohibition.

Q3832607 Química
O hidróxido de lítio (LiOH) é amplamente utilizado como um agente de captura de dióxido de carbono (CO₂) em ambientes fechados, como submarinos e espaçonaves, onde o controle da qualidade do ar é essencial para a sobrevivência da tripulação. Esse composto reage com o CO2,: formando carbonato de lítio (Li₂CO3) e água (H2O), removendo assim o gás tóxico do ambiente. A reação é representada pela seguinte equação química:

CO2(g) + 2 LiOH(s) → Li2CO3(s) + H2O(1)

Para remover o CO2 de um compartimento de um submarino, foram utilizados 400 mols de LiOH. Assim, qual é a massa de carbonato de lítio (Li2CO3) formada, em quilogramas (kg)?

As bactérias apresentam grande diversidade de espécies e possuem uma variedade de mecanismos de recombinação genética tanto de maneira vertical quanto horizontal: Fato que contribui para a variabilidade genética e facilitao fenômeno de resistência aos antibióticos, quando se trata de bactérias patogênicas. Além disso, as bactérias podem ser divididas em autotróficas e heterotróficas e com essas diferentes formas de obtenção de energia, podem se distribuir pelos mais variados ambientes. Sobre o metabolismo energético bacteriano е os processos de transferência de material genético, analise as afirmativas abaixo.

I- A conjugação bacteriana é um mecanismo de recombinação genética em que uma bactéria engloba genes dispersos no ambiente por outra bactéria.
II- Na transdução bacteriana a participação dos fagos é fundamental, pois são vírus que transportam genes de uma célula bacteriana para outra.
III- As bactérias autotróficas podem realizar quimiossíntese, neste caso, podem obter energia da oxidação de substâncias inorgânicas como amônia (NH3) e sulfeto de hidrogênio (H₂S).
IV- As bactérias heterotróficas podem fazer fermentação, processo no qual a glicose (C6H12O6) é degradada na presença de oxigênio (O2), eliminando gás carbônico (CO2) e água (H₂O).

Para o Brasil, uma das consequências do conflito foi que o país ficou ainda mais endividado com a Inglaterra, com a qual tinha restaurado as relações diplomáticas, no início das hostilidades. Mas a maior consequência foi a afirmação do Exército como uma instituição com fisionomia e objetivos próprios. Entre outros pontos, as queixas contra o governo do império, que vinham de longe, ganharam outra expressão. Afinal de contas, o Exército sustentara a luta na frente de batalha, com seus acertos e erros. Enquanto isso, as elites civis — os casacas , como passaram a ser desdenhosamente chamados — haviam ficado a salvo e, em certos casos, enriqueceram com os negócios de fornecimento para a tropa.
