High failure rates in the Differential and Integral Calculus courses and the subsequent dropout caused by them are a reason for concern in many universities around the world, both in developing countries such as Brazil and developed ones such as the United States of America. So, it is not surprising that there is lots of interest in researching about this context, and possible ways of action. This is the focus of this article, to study about the origins of this situation, analyzing the causes of the students’ difficulties and presenting Collaborative Learning as an effective way to change this situation. The article is based on data from several universities that have shown interest in this method. The results demonstrate the effectiveness of this practice, both in academic and psychological performance of the students, thus showing the need for a greater incentive of this technique, as well as an intense study of the way it should be done.

In recent years, the development of a dangerous fad in which young people use clove cigarettes as an alternative to conventional cigarettes has occurred in several areas of the United States and Canada. Many users have the mistaken belief that clove cigarettes are an herbal, "natural," nontobacco alternative. Others are attracted to their use because of the association of clove cigarettes with the image of surfing, New Wave music, and the search for "exotic" and unusual experiences. More than 170 million clove cigarettes were sold at the height of their popularity in 1984, and sales were still averaging more than 40 million per year in 1985, 1986, and 1987.1(p3) This is even more remarkable when one considers that a significant portion of the consumers are under the legal age of purchase and that these sales have been achieved without the assistance of overt advertising. Indeed, a recent report of California youth in the 10th grade showed that 23% had tried clove cigarettes at least once. Furthermore, one third of those, approximately 8.5%, had used them at least once per month.2 Clove cigarettes are imported from Southeast Asia, principally from Indonesia, and are composed of approximately one third shredded cloves and two thirds tobacco. The type of tobacco in a clove cigarette delivers approximately twice as much tars, nicotine, and carbon monoxide as does tobacco in ordinary American cigarettes.1(pvi) In addition, substantial amounts of eugenol, an anesthetic agent, are found in cloves and in the smoke of clove cigarettes. The typical clove cigarette smoker inhales approximately 7 mg of eugenol per clove cigarette.

Carbon monoxide (CO) is responsible for more fatalities in the United States each year than any other toxicant. While CO exposure is a year-round problem, fatal and nonfatal CO exposures occurred more often during the fall and winter months, and the majority of nonfatal CO exposures were reported to occur in the home. Postdisaster CO poisoning is an emerging hazard. Unintentional CO poisonings have been documented after natural disasters like hurricanes, floods, ice storms, and power outages. Overwhelmingly, CO exposure results from common sources such as portable generators, gas grills, kerosene and propane heaters, pressure washers, and charcoal briquettes. Although disaster events are thought to create victims immediately and in great numbers during the initial impact, some disasters are more deadly to people during the recovery phase, when people are thinking the disaster is over. More are injured during the cleanup phase than from the storm itself.

Accidental or intentional carbon monoxide poisoning is common throughout the year. In the Midwest, however, accidental exposures are more common during the winter months when the furnaces are overworked or malfunction. Consequently, enmasse exposures to the poisonous gas are frequently encountered during this season. Adding to the problem are the energy conservation efforts. Doors, windows and other ventilation avenues are tightly sealed, and solid fuel might be substituted to save other expensive conventional fuels. Other causes of carbon monoxide poisoning are blocked exhaust systems, automobiles with inadequate mufflers, fires and solvent (methylene chloride, etc.) usage in poorly ventilated areas, e.g., basements. The exact incidence of nonfatal subacute carbon monoxide poisoning is not available. National Clearinghouse Bulletin reported that in 1978, out of 376 reported exposures, there were eight fatalities. A figure which has been frequently quoted in the literature is that each year in the United States, approximately 3,500 deaths are caused by carbon monoxide poisoning.

Public policy regulations, designed to legitimate and protect fragile, fledgling new firms from failure, on the surface, appear to be of great value. According to Stinchcombe, to the extent that such policies serve as “standard social routines,” they may even work to decrease the liability of newness. Using a sample of more than 2,600 new banks chartered in the United States over a 15-year span under the supervision of three different regulatory agencies, we find that failure rates vary according to nuances in the differences in regulations levied by these agencies. Paradoxically, banks that are initially subject to more stringent regulations, intended to limit their strategic choices to a set of “safe and sound” practices, and protect them from failure during their early stages of existence, in fact, have a higher likelihood of failure after those restrictive regulations are lifted. Our results suggest that public policy attempts to thwart the liability of newness are in fact a “fix that fails,” as public policy regulations designed to reduce the liability of newness merely delay the inevitable.
