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.

public class Exemplo{
public static void main(String[] args)
{
double d1 = 0.0;
double d2 = 0.0;
double d3 = 0.0;
double d4 = 0.0;
media (d1);
media (d1 , d2);
media (d1, d2, d3);
media (d1, d2, d3, d4);
}
}
O programador utilizou um único método media, sem uso de sobrecarga de método.
Analise as afirmativas abaixo e assinale corretamente a que representa uma assinatura válida do método media para o código apresentado e que possibilite receber uma lista de argumentos de tamanho variável.
public class Codigo {
public static void main(String[ ] args)
{
try { throwException (); }
catch (Exception exception) { System.out.printf (" 1 ");}
}
public static void throwException () throws Exception
{
try { System.out.printf (" 2 "); throw new Exception (); }
catch (RuntimeException runtimeException) { System.out.printf (" 3 ");}
finally {System.out.printf (" 4 ");}
}
}
Teremos como saída a sequência:
Considerando o modelo proposto pelo PMI (Project Management Institute) para o gerenciamento de projetos, assinale corretamente qual documento formaliza essa etapa.
( ) Os Sistemas de Apoio à Decisão fornecem apoio interativo ad hoc a seus usuários e possibilitam a análise de um grande número de variáveis a fim de um posicionamento sobre determinada questão.
( ) Os sistemas colaborativos pertencem ao grupo de Sistemas de Apoio Gerencial e possuem a função de monitorar e controlar processos físicos em plantas industriais.
( ) Os sistemas de Gerenciamento da Cadeia de Suprimentos (SCM) possuem como função a integração e automação dos processos de atendimento ao cliente nas áreas de vendas, marketing e serviços de produto com o intuito de aproximá-los à empresa.
Pela técnica de Análise de Pontos de Função, como função de Transação, a rotina acima descrita deve ser pontuada como:
( ) O padrão de projeto ITERATOR pertence ao grupo de propósito COMPORTAMENTAL, o qual trata as interações e divisões de responsabilidades entre as classes ou objetos.
( ) O padrão de projeto ADAPTER pertence ao grupo de propósito de CRIAÇÃO, o qual se preocupa com o processo de criação de objetos.
( ) O padrão de projeto BRIDGE pertence ao grupo de propósito ESTRUTURAL, o qual lida com a composição de classes ou objetos.
Padrão de Projeto
1. OBSERVER
2. COMMAND
3. FLYWEIGHT
4. ITERATOR
5. MEMENTO
Intenção do Padrão de Projeto
( ) Utiliza compartilhamento para suportar de maneira eficiente grandes quantidades de objetos com granularidade fina.
( ) Permite armazenar o estado interno de um objeto em um determinado momento para que se possa ser restaurá-lo quando necessário.
( ) Define uma dependência um-para-muitos entre objetos de modo que, quando um objeto muda de estado, todos os seus dependentes são automaticamente notificados e atualizados.
#include <stdio.h>
int funcao (int *x, int y)
{
if (y > 9)
return (1);
else
if (x [y] > 3)
return (x [y] + funcao (x, y+1 ));
else
return (x [y] * funcao (x, y+1));
}
int main ()
{
int vetor [ ] = {1,1,2,3,4,5,6,7,8,9};
int resultado = funcao (vetor, 0);
for (int i=0; i < 10; ++i) {
printf ("%d" , vetor [i]);
if (i<9)
printf (",");
}
}
São palavras reservadas da linguagem C no padrão ANSI e, portanto, não podem ser utilizadas como nomes de variáveis em programas inscritos nesta linguagem:
I. overall.
II. union.
III. extern.
IV.signed.
V. code.
#include <stdio.h>
int main ( ) {
int v [ ] = {20, 35, 76, 80};
int *a;
a = &v [1];
--(*++a);
(*a--)= (*++a) + 1;
(*a) = --(*--a);
printf ("%d, %d, %d, %d\n", v[0], v[1], v[2], v[3]);
}
#include <stdio.h>
int main () {
int numero = 20;
printf ("%o + %x = %04d", numero, numero, numero * 5);
}

Propriedade de uma Transação
1. Atomicidade
2. Consistência
3. Isolamento
4. Durabilidade
5. Objetividade
Característica da Propriedade
( ) Caracteriza a persistência dos efeitos de uma transação sobre uma base de dados em caso de sucesso de sua execução (commit).
( ) Representa a capacidade de uma transação ter todas as suas operações executadas ou nenhuma delas.
( ) Garante que as atualizações de uma dada transação sejam ocultas de outras que estejam sendo executadas em modo concorrente, até o momento de seu término.
( ) A tarefa de agrupamento de dados consiste em agrupar um conjunto de registros em dois ou mais grupos, com base em alguma medida de semelhança ou de proximidade entre os valores dos atributos que os compõem.
( ) Na tarefa de associação os padrões de dados descobertos são apresentados na forma de regras do tipo A →C, onde A e C representam, respectivamente, o antecedente e o consequente da regra.
( ) Os algoritmos para construção de árvores de decisão, como o ID3 e C4.5, são utilizados na tarefa de classificação.
