Racial and ethnic relations in the United States are better today than in the past, but many changes are needed before sports are a model of inclusion and fairness. The challenges today are different from the ones faced twenty years ago, and experience shows that when current challenges are met, a new social situation is created in which new challenges emerge. For example, once racial and ethnic segregation is eliminated and people come together, they must learn to live, work, and play with each other despite diverse experiences and cultural perspectives. Meeting this challenge requires a commitment to equal treatment, plus learning about the perspectives of others, understanding how they define and give meaning to the world, and then determining how to form and maintain relationships while respecting differences, making compromises, and supporting one another in the pursuit of goals that may not always be shared. None of this is easy, and challenges are never met once and for all time.

Paul Harvey tells the story of how an Eskimo kills a wolf. First, the Eskimo coats his knife blade with animal blood and allows it to freeze. Then he adds another layer of blood, and another, until the blade is completely concealed by frozen blood. Next, the hunter fixes his knife in the ground with the blade up. When a wolf follows his sensitive nose to the source of the scent and discovers the bait, he licks it, tasting the fresh frozen blood. He begins to lick faster, more and more vigorously, lapping the blade until the keen edge is bare. So great becomes his craving for blood that the wolf does not notice the razor-sharp sting of the naked blade on his own tongue, nor does he recognize the instant at which his insatiable thirst is being satisfied by his OWN warm blood. His carnivorous appetite just craves more - until the dawn finds him dead in the snow!

Fasting is one of the best ways to remove toxic material from the body. The process gives the body's enzymes "time off" from working on foods so they can devote time to detoxification. During fasting, the body's enzyme system is cleaning up and digesting and eliminating damaged tissues and foods that have been hard to digest. While fasting reduces the risks of weight-related diseases such as diabetes and hypertension, it also helps clear the body of toxic wastes. About six hours after the last meal, the body starts to use glycogen, which is a carbohydrate stored in the liver and muscles. When there is no food in the stomach, the body stops the process of assimilation and concentrates on getting rid of toxins and other waste products.

Uncertainty is an inescapable feature of science that, counterintuitive as it might sound, does not prevent us from gaining scientific knowledge and understanding. As individuals, and as societies, we need to understand and accept uncertainty in science. Perhaps surprisingly, it is because of this feature that science has made, and still makes, important advancements. Uncertainty motivates further research and a better understanding of natural phenomena. Scientific knowledge is perhaps the sort of knowledge that is as close to certainty as we can get, but this only means that it is closer to being certain than other kinds of knowledge, not that it is absolutely so. Whereas nothing compares to scientific knowledge when it comes to understanding the natural world around us, such knowledge is at the same time flexible enough to accommodate new findings. This happens because continuous research deals better and better with uncertainty and produces an increasingly reliable body of knowledge on the basis of solid evidence and rational thinking.

In the booming global travel business, ecotourism is among the fastest-growing segments. Costa Rica and Belize have built national identities around their celebrated environmental allure, while parts of the world once all but inaccessible-from Antarctica to the Galapagos Islands to Mount Everest-are now featured in travel guides, just like Manhattan, Rome and other less exotic destinations. Advocates see ecotourism as a powerful yet environmental-friendly tool for sustainable economic development in even the poorest nations. But as the trend expands, critics see threats to the very flora and fauna tourists flock to visit. Moreover, traditional subsistence cultures may be obliterated by the ecotourism attack, replaced by service jobs that pay native peoples poverty wages. Meanwhile, tour promoters are using the increasingly popular "green" label to attract visitors to places unable to withstand large numbers of tourists.

To begin with a psychological reason, the knowledge of another's personal affairs can tempt the possessor of this information to repeat it as gossip because as unrevealed information it remains socially inactive. Only when the information is repeated can its possessor turn the fact that he knows something into something socially valuable like social recognition, prestige, and notoriety. As long as he keeps his information to himself, he may feel superior to those who do not know it. But knowing and not telling does not give him that feeling of "superiority that, so to say, latently contained in the secret, fully actualizes itself only at the moment of disclosure." This is the main motive for gossiping about well-known figures and superiors. The producer assumes that some of the "fame" of the subject of gossip, as whose "friend" he presents himself, will rub off on him.

Why do we find it so difficult to slow down? We may, in part, be the inheritors of a Protestant ethic which encourages us to believe that time must be used 'productively' and 'efficiently.' We feel we should be getting things done, ticking them off a list. But it could be that many of us are driven by fear. We are so afraid of having longer, emptier hours that we fill them with distractions or strive to stay occupied. How often do we sit quietly on the sofa for half an hour without switching on the television, picking up a magazine or making a phone call, and instead just thinking? Within minutes we find ourselves channel-surfing and multitasking. What exactly are we afraid of? On some level we fear boredom. A deeper explanation is that we are afraid that an extended pause would give us the time to realize that our lives are not as meaningful and fulfilled as we would like them to be. The time for contemplation has become an object of fear.

Everybody knows the population of the world is growing. But remarkably few people seem to know that the rate of increase in world population has been falling since the early 1960s and that the raw number of new people added each year has been falling since the late 1980s. As the environmentalist Stewart Brand puts it, "Most environmentalists still haven't got the word. Worldwide, birth rates are in free fall. On every part of every continent and in every culture, birth rates are headed down. They reach replacement level and keep on dropping." This is happening despite people living longer and thus increasing the numbers of the world population for longer, and despite the fact that babies are no longer dying as frequently as they did in the early twentieth century. Population growth is slowing even while death rates are falling.

Social psychologists have debated for decades the question of whether consistency is rooted in nature or nurture. Cultural variation would be one indication that it is learned. Some evidence indicates that the same basic drive for consistency can be found in very different cultures, but making choices does not seem to cause dissonance processes among East Asians the way it does for North Americans. On the other hand, the influence of social pressures toward consistency probably strengthens the drive. Either way, the root probably lies in the fact that groups of people can get along better if the people understand each other, and understanding each other is easier if people are somewhat consistent. People expect and pressure each other to be consistent, and people respond to these pressures and expectations by seeking to be consistent. Quite possibly the drive for consistency is rooted in our biological nature and strengthened by learning and socialization.

Joost Smiers, director of the Centre for Research at the Utrecht School of the Arts, stated that it is important to discuss the abolition of copyrights, which are now mainly in the hands of the transnational cultural conglomerates. In his eyes, this economic concentration of power and rights damages free artistic and cultural developments, on both a local and global level. In general, art and culture are not an expression of the individual genius artist but have their roots in the historical developments of culture. If (Western) conglomerates claim their collected copyrights for profit reasons, they hinder artists and developing countries in processing existing cultural expressions and creating new ones. One of the alternatives could be to establish a cultural fund, fed by tax from companies that use the expressions of artistic values for their own purpose. With the financial support of such a fund, artists and developing countries will be stimulated to contribute to free cultural living.

Suppose we know that Paula suffers from a severe phobia. If we reason that Paula is afraid either of snakes or spiders, and then establish that she is not afraid of snakes, we will conclude that Paula is afraid of spiders. However, our conclusion is reasonable only if Paula's fear really does concern either snakes or spiders. If we know only that Paula has a phobia, then the fact that she's not afraid of snakes is entirely consistent with her being afraid of heights, water, dogs or the number thirteen. More generally, when we are presented with a list of alternative explanations for some phenomenon, and are then persuaded that all but one of those explanations are unsatisfactory, we should pause to reflect. Before conceding that the remaining explanation is the correct one, consider whether other plausible options are being ignored or overlooked. The fallacy of false choice misleads when we're insufficiently attentive to an important hidden assumption, that the choices which have been made explicit exhaust the sensible alternatives.

When a young man commits himself to a woman in the Sacrament of Marriage, he makes a vow to love her regardless of his feelings. What does this mean? As time passes and the trials of life weigh down, the couple may not feel the sentiments of love. Because many people have a wrong understanding of love, they feel justified to leave the marriage and look for those same feelings in another person. This makes sense if we reduce love to mere feelings. True marital love, however, understands that the commitment transcends subjective feelings. The feelings may have been necessary at the beginning of courtship, but if it evolves into true love, feelings become secondary. Marriage is about a choice to commit one's life to another for their well-being regardless of emotions.

One of the interesting examples of nonverbal communication in impression management is Goffman's body gloss. In this process, individuals exhibit behavior designed to cover or gloss over a potentially negative incident and thereby reduce observers' unfavorable impressions. That is, body gloss frequently involves an actor playing to observers of a particular event. Thus, body gloss is unnecessary when there is no audience to impress. Unlike much of other nonverbal communication, however, this behavior is not necessarily interactive and conscious. Most of us have seen incidents of body gloss and, on occasion, have been actors in such performances, even if we were unaware of it.

Fluorine is a chemical element that is present in the environment. When bones are formed, they do not contain much fluoride, but they absorb it from the environment over time. In other words, the older a bone is, the more fluoride it has, so by measuring that amount we can know its age. It was found that the Piltdown remains had minimal amounts of fluoride, so it was clear that they had been buried recently. The news was sensational, especially in countries such as France and Germany, although, it has to be said, also in Great Britain and the United States, the latter a country where there were scientists who had doubted the English 'presapiens'. Yet many supporters of Piltdown Man - journalists and palaeontologists - refused to acknowledge the evidence provided by the fluoride. It was in 1953 that other analyses revealed that the remains had been dyed to give them an antique appearance and, worst of all, the teeth of the jaw, which turned out to be from an orangutan, had been filed down to give them a human look.

Experiments are good for testing the effects of 'treatments'; a treatment being the variable or stimulus that you are changing in order to test a differential response. For example, which web page configuration users prefer. This can be done covertly online by simply randomly exposing two groups to the two different configurations. If the dependent variable/objective is time on site then you can readily determine which website configuration leads to greater engagement. The overt/active lab-based experiment is most suited to studies seeking to determine psychological factors (though the lab can be virtual/online) and generally these are the preserve of academic inquiry. A company could employ a lab-based experiment to test differential reactions to two forms of packaging, for example. The problem with the lab experiment is that it tends to isolate a stimulus or effect. People make decisions and buy things in the real, noisy world where various other things influence and distract you.
