ARE YOU A FACEBOOK ADDICT?
Are you a social media enthusiast or simply a Facebook addict? Researchers from Norway have developed a new instrument to measure Facebook addiction, the Bergen Facebook Addiction Scale.
"The use of Facebook has increased rapidly. We are dealing with a subdivision of Internet addiction connected to social media," Doctor of Psychology Cecilie Schou Andreassen says about the study, which is the first of its kind worldwide.
Andreassen heads the research project "Facebook Addiction" at the University of Bergen (UiB). An article about the results has just been published in the renowned journal Psychological Reports. She has clear views as to why some people develop Facebook dependency.
"It occurs more regularly among younger than older users. We have also found that people who are anxious and socially insecure use Facebook more than those with lower scores on those traits, probably because those who are anxious find it easier to communicate via social media than face-to- face," Andreassen says.
People who are organised and more ambitious tend to be less at risk from Facebook addiction. They will often use social media as an integral part of work and networking.
"Our research also indicates that women are more at risk of developing Facebook addiction, probably due to the social nature of Facebook," Andreassen says.
Six warning signs
As Facebook has become as ubiquitous as television in our everyday lives, it is becoming increasingly difficult for many people to know if they are addicted to social media. Andreassen’s study shows that the symptoms of Facebook addiction resemble those of drug addiction, alcohol addiction and chemical substance addiction.
The Bergen Facebook Addiction Scale is based on six basic criteria, where all items are scored on the following scale: (1) Very rarely, (2) Rarely, (3) Sometimes, (4) Often, (5)Very often, and (6) Always.
• You spend a lot of time thinking about Facebook or planning to use of Facebook.
• You feel an urge to use Facebook more and more.
• You use Facebook in order to forget about personal problems.
• You have tried to cut down on the use of Facebook without success.
• You become restless or troubled if you are prohibited from using Facebook.
• You use Facebook so much that it has had a negative impact on your job/studies.
Andreassen’s study shows that scoring “often” or “very often” on at least four of the six items may suggest that you are addicted to Facebook.

A questão refere-se ao trecho do texto 1, destacado a seguir:
“Olhando os enigmas que nos rodeiam e ponderando e analisando as minhas observações, entro em contato com o mundo da matemática.”
Em qual dos trechos a seguir o uso da vírgula justifica-se pelo mesmo motivo que a vírgula foi usada no período destacado?
Leia atentamente as assertivas a seguir, todas relacionadas aos textos 1,2 e 3.
I – O fato de Escher não ter sido um bom aluno mostra que ele não tinha aptidão para desenvolver raciocínios abstratos.
II – A ligação entre os conceitos matemáticos desenvolvidos na obra de M. C. Escher é de ordem puramente do acaso, haja vista sua comprovada dificuldade para entender a matemática ensinada na escola.
III – A habilidade de calcular usando números e símbolos expressa uma das maneiras de demonstrar a aquisição de conceitos matemáticos, mas não a única maneira.
IV – A obra de Escher surpreende inclusive os mais renomados catedráticos da matemática por sua inovadora maneira de transformar em arte abstrações matemáticas pensadas habitualmente apenas nos tradicionais ambientes de ensino.
Dentre as afirmativas acima, quais estão corretas?
H2O(g) + C(s) + 31,4 kcal ⇄ CO(g) + H2(g)
pode-se afirmar que:
Um volume V1 de oxigênio e um volume V2 de ácido sulfídrico, ambos nas mesmas condições de temperatura e pressão, são misturados. Promovendo-se a reação completa, verifica-se que os produtos da reação, quando colocados nas condições iniciais de pressão e temperatura, ocupam um volume de 10 L.
Considere que a água formada encontra-se no estado líquido e que as solubilidades dos gases em água são desprezíveis. Sabendo-se que havia oxigênio em excesso na reação e que V1 + V2 = 24 L, verifica-se que o valor de V2 é:
2 d senθ= λ
onde λ é o comprimento de onda do feixe monocromático de radiação X incidente sobre a amostra, θ é o ângulo no qual se observa interferência de onda construtiva e d é o espaçamento entre as camadas de átomos na amostra.
Ao se incidir raios X de comprimento de onda de 154 pm sobre uma amostra de um metalóide, cuja cela unitária segue a representação da figura abaixo, observa-se interferência construtiva em 13,3°.
De acordo com as tabelas 1 e 2, pode-se afirmar que o metalóide analisado é:
t (s) C1 ( mol/L) C2 ( mol/L) C3 ( mol/L)
200 0,8000 0,8333 0,8186
210 0,7900 0,8264 0,8105
220 0,7800 0,8196 0,8024
230 0,7700 0,8130 0,7945
240 0,7600 0,8064 0,7866
Considere que o modelo ∆c ⁄∆t = − KCn descreva adequadamente as velocidades das reações estudadas. Considere ainda que as magnitudes das constantes de velocidade específica de todas as reações são idênticas à da reação de segunda ordem, que é 1,0 x10-3 L/mol.s. Assim, pode-se afirmar que C1, C2 e C3 referem-se, respectivamente, a reações de ordem
