We are always teaching our children something by our words and our actions. They learn from seeing. They learn from hearing and from overhearing. Children share the values of their parents about the most important things in life. Our priorities and principles and our examples of good behavior can teach our children to take the high road when other roads look tempting. Remember that children do not learn the values that make up strong character simply by being told about them. They learn by seeing the people around them act on and uphold those values in their daily lives. Therefore show your child good examples of life by your action. In our daily lives, we can show our children that we respect others. We can show them our compassion and concern when others are suffering, and our own self-discipline, courage and honesty as we make difficult decisions.

Most people have no doubt heard this question: If a tree falls in the forest and there is no one there to hear it fall, does it make a sound? The correct answer is no. Sound is more than pressure waves, and indeed there can be no sound without a hearer. And similarly, scientific communication is a two-way process. Just as a signal of any kind is useless unless it is perceived, a published scientific paper (signal) is useless unless it is both received and understood by its intended audience. Thus we can restate the axiom of science as follows: A scientific experiment is not complete until the results have been published and understood. Publication is no more than pressure waves unless the published paper is understood. Too many scientific papers fall silently in the woods.

We all negotiate every day, whether we realise it or not. Yet few people ever learn how to negotiate. Those who do usually learn the traditional, win-lose negotiating style rather than an approach that is likely to result in a win-win agreement. This old-school, adversarial approach may be useful in a one-off negotiation where you will probably not deal with that person again. However, such transactions are becoming increasingly rare, because most of us deal with the same people repeatedly — our spouses and children, our friends and colleagues, our customers and clients. In view of this, it's essential to achieve successful results for ourselves and maintain a healthy relationship with our negotiating partners at the same time. In today's interdependent world of business partnerships and long-term relationships, a win-win outcome is fast becoming the only acceptable result.

The interaction of workers from different cultural backgrounds with the host population might increase productivity due to positive externalities like knowledge spillovers. This is only an advantage up to a certain degree. When the variety of backgrounds is too large, fractionalization may cause excessive transaction costs for communication, which may lower productivity. Diversity not only impacts the labour market, but may also affect the quality of life in a location. A tolerant native population may value a multicultural city or region because of an increase in the range of available goods and services. On the other hand, diversity could be perceived as an unattractive feature if natives perceive it as a distortion of what they consider to be their national identity. They might even discriminate against other ethnic groups and they might fear that social conflicts between different foreign nationalities are imported into their own neighbourhood.
