The Internet offers access to a wealth of material that is
personally, professionally and culturally enriching to individuals
of all ages. However, it also enables access to some material that
may be offensive, disturbing, illegal, inaccurate or incomplete.
Users are encouraged to evaluate the validity and appropriateness
of information accessed via the Internet.
Tests by the library and by independent agencies have shown that
filtering software may help to block access to objectionable
Internet sites. However, the software cannot block out all
objectionable sites, and it does sometimes block useful material,
including sites that are suitable for children, teens and adults.

Q43309

One frequently overlooked area in planning is technical
reviews and inspections. A technical review requires substantial
preparation on the part of the presenters. Documents must be
published and distributed and presentation material organized and
made into slides or overheads. Practice sessions are conducted by
presenters with an audience of critics to prepare for the review.
The reviewers should read the material, attend the
presentations, and write reports. On large projects with many
reviews and walk-throughs involving many participants, a
substantial number of labor hours can be consumed analyzing
documents, attending meetings, and writing reports. For example,
a system design review for one module or unit can require 150
labor hours. When overlooked, this labor can result in a very
large error in resource and schedule estimation.
Many projects include risk assessment and risk
management as a key part of the planning process and expect the
plan to identify specific risk areas. The plan is expected to
quantify both probability of failure and consequences of failure
and to describe what will be done to contain development risk.

Uma empresa de consultoria realizou um levantamento estatístico para obter informações acerca do tempo (T) gasto por empregados de empresas brasileiras na Internet em sítios pessoais durante suas semanas de trabalho. Com base em uma amostra aleatória de 900 empregados de empresas brasileiras com um regime de trabalho de 44 h semanais, essa empresa de consultoria concluiu que cada empregado gasta, em média, 6 h semanais na Internet em sítios pessoais durante uma semana de trabalho; 50% dos empregados gastam 5 h semanais ou mais na Internet em sítios pessoais durante uma semana de trabalho; e o desvio padrão do tempo gasto na Internet em sítios pessoais durante o regime de trabalho é igual a 4 h semanais por empregado.

Raciocínio Lógico
Texto associado
Uma proposição é uma sentença que pode ser julgada
verdadeira (V) ou falsa (F). As proposições são normalmente
representadas pelas letras maiúsculas A, B, C etc. A partir de
proposições dadas, podem-se construir novas proposições
compostas, mediante o emprego de símbolos lógicos chamados
conectivos: "e", indicado pelo símbolo lógico
, e "ou", indicado pelo símbolo lógico 
. Usa-se o modificador "não", representado pelo símbolo lógico ¬, para produzir a negação de uma
proposição; pode-se, também, construir novas proposições
mediante o uso do condicional "se A então B", representado
por A
B.O julgamento de uma proposição lógica composta
depende do julgamento que se faz de suas proposições
componentes. Considerando os possíveis julgamentos V ou F das
proposições A e B, tem-se a seguinte tabela-verdade para
algumas proposições compostas.
Considerando-se a proposição A, formada a partir das
proposições B, C etc. mediante o emprego de conectivos (
ou
), ou de modificador (¬) ou de condicional (
), diz-se que A é uma tautologia quando A tem valor lógico V, dependentemente
dos valores lógicos de B, C etc. e diz-se que A é uma contradição
quando A tem valor lógico F, independentemente dos valores
lógicos de B, C etc. Uma proposição A é equivalente a uma
proposição B quando A e B têm as tabelas-verdade iguais, isto é,
A e B têm sempre o mesmo valor lógico.
