A menudo se escribe sobre el binomio jóvenes y

redes sociales, utilizando datos de diversos estudios que

aportan luz sobre cómo manejan estas plataformas de

comunicación niños y adolescentes.

[5]     ¿Por qué los jóvenes quieren ser (a toda costa)

populares en las redes sociales?

    Luis Alfonso Aguirre, estudiante, cree que “en la

sociedad que nos toca vivir, las redes sociales no solo son

inevitables, son imprescindibles. Para alguien de 15 años

[10] de edad como yo, la no utilización de estas plataformas

puede condenarle a la exclusión social en el corto plazo”.

    Coincide en esta opinión la estudiante Paula

Martínez, de 17 años de edad, quien sobre todo utiliza

grupos de WhatsApp e Instagram Stories para compartir

[15] con su grupo su día a día personal y estudiantil. “Me

preocupa que algunos de mis amigos y amigas no tengan

suficiente cuidado a la hora de compartir su vida más

personal”, afirma. “Además — añade — parece que hay

cierta presión por compartir imágenes en las que todos

[20] ofrecemos la mejor de nuestras caras ocultando problemas

para cuya solución es preciso recurrir al contacto personal

con los amigos, pero también con la familia o profesores”.

    Este excesivo interés por la popularidad en las redes

también preocupa a Paula. “A veces hay cierta obsesión

[25] por conseguir likes porque casi se ha convertido en una vía

para conseguir la integración en el grupo. Eso lleva a que,

en ocasiones, no disfrutemos de los momentos que vivimos

y no son fotografiables y busquemos siempre situaciones y

escenarios atractivos que podamos compartir en las redes

[30] Sociales con ciertas posibilidades de conseguir un me

gusta", explica.

    Diego Martínez, estudiante de 19 años de edad, cree

que, como todo en la vida, "el tiempo hace que vayamos

utilizando mejor las redes sociales, racionalizando su uso y

[35] situándolas en el lugar adecuado en nuestras vidas".

Cree esencial que "los adultos acompañen en este

proceso a los más jóvenes cuando se introducen en el uso

de las redes sociales". "De la misma manera que padres y

educadores toman de la mano a sus hijos para enseñarles a

[40] cruzar la carretera, deben estar dispuestos a estar a su lado

cuando cruzan del mundo offline al mundo digital".

    Desde luego, rechazar, demonizar o incluso prohibir

el uso de las redes sociales entre los jóvenes no puede ser

la solución para evitar los riesgos de un mal uso, concluye

[45] Luís Afonso.

(UCS) Special delivery

The other day in our mailbox there was a letter from Auntie Anne. She is nearing 80 and does not know how important Facebook has become. She is not interested in Twittering and does not see the use of Internet. She is addicted to pen and paper.

Every other week for the past 30 years I have sat down and written a letter to her. I started writing to her when I was 10 and she was living at Lake Ranch in the interior of British Columbia. Her letters were full of what Uncle Willi was doing. He was a cowboy and he rode quarter horses every day, moving cattle and watching out for rattle-snakes.

Her correspondence was like a novel ¹whose main characters were my family, and I still have every letter. My letters were full of school in Victoria and family and ballet. I learned to ²pack mine with ³whatever I thought was important. She would write back with questions and slowly I learned how to tell a story. I also learned about the paraphernalia of letter writing, keeping my address book current, having a ready supply of paper, envelopes and stamps.

I caught the letter-writing bug myself. While still home in Victoria and studying at university, I wrote to friends who were studying and living in France and China. We shared our ⁴hopes and travels, and chronicled our love lives. I have boxes filled with their letters.

Once graduated from university, I packed my backpack and traveled around the world. My letters reached Auntie Anne from Asia and Europe. Places she had never seen, but ⁷was keen to hear all about. When ⁸I was homesick, letters from my family would find me everywhere and I would feel like the world was smaller. Someone out there cared.

Nowadays most wired people muse that ⁹snail mail is not all that relevant any more. Nobody uses the mail these days, they say. When was the last time someone ⁵actually wrote a letter? But what about postcards when you travel? What about the small businesses who rely on cheques in the mail? What about all those charities needing funds to carry on? What about all those things you order online? Who makes them come right to your door?

Now that the kids are out of school it seems the perfect time to get them to write to Auntie Anne. I coach them on the rules of writing to her. She does not like fancy paper any more. She thinks it is better to recycle a flyer from the mailbox or the back of the newsletter from my daughter´s preschool. We need to always use the formal salutation “dear” and formal closing “love”, because being dear to someone and telling them we love them is what we all want to get in the mail.

Auntie Anne always includes a note for each child with questions of their own to answer in a letter back to her. They usually carry her notes around and use them for bookmarkers for days afterward or dance around holding the letter in their hands.

I keep an addressed envelope on the kitchen counter ready in case I see a clipping from the newspaper I know Auntie Anne will be interested in, or a nice bit of artwork from the children or perhaps even a note written by them.

¹⁰As I mail my ⁶parcel to Auntie Anne, perhaps in the next week or so we will receive another letter from her. Because if we want a letter, we must first write one.

(G1 - cftsc)  Em 2009, comemorou-se o bicentenário de nascimento do naturalista Charles Darwin

(1809-1882), assim como os 150 anos de publicação da sua obra Origem das espécies (1859). Charles Darwin, assim como diversos outros naturalistas e pesquisadores contribuíram para o entendimento atual da evolução biológica. No mesmo ano de nascimento de Darwin, Jean Baptiste Lamarck (1744-1829) publicou sua obra Filosofia Zoológica, na qual defende as hipóteses do uso e desuso e da transmissão hereditária dos caracteres adquiridos.
