Introducing people

Before mechanical refrigeration systems were introduced, people cooled their food with ice and snow, found or made on-site or gathered in the mountains. This practice survives today in the Taurus Mountains of Turkey. Ice was stored in icehouses usually partially buried in the ground and lined with straw or sawdust. Remains of these structures survive on many farms in Europe and North America. Ice has long been used for space comfort conditioning. In the early nineteenth century, ice was placed in air ducts to cool and dehumidify warm air blown by fans. 

Gateway drug—Theory of drug enforcers who argue that even if Marijuana is not in the same class as certain narcotics, it should be treated the same way because it introduces people, especially the young, to those "harder" drugs.

Once implementation is complete (i.e., the software is installed, in use, and actually works), there is a continued need for the implementation process to continue. All the staff who use the system need to be retrained and any problems resolved. The training sessions themselves only introduce people. The actual training is on-the-job training, as everyone tries to accomplish his/her job using the system.

After the concept of science of safety (or safety science) has been introduced, people would ask me about its actual meaning and import. This book is an attempt to introduce the science of safety in a comprehensive form and in its fundamental characteristics. Its intrinsic interdisciplinary character made it necessary to enlist the help of a group of experts from various and vastly different fields. Working... 

The course instructors or professors have not tried to intentionally deceive their students. Most individuals cannot grasp the full depth and detail of any chemical concept the first time that it is presented to them. It has been found that most people learn complex subjects best when first given a basic description of the concepts and then left to develop a more detailed understanding over time. Despite the best elforts of educators, a few misconceptions are at times possibly introduced in the attempt to simplify complex material for freshmen students. The part of this process that perpetuates any confusion is the fact that texts and instructors alike often do not acknowledge the simplifications being presented. 

The People s RepubHc of China introduced Kuraray technology and started production of PVA fiber by a wet spinning process in 1965. Its annual capacity reached 165,000 tons in 1986 (9). The Democratic People s RepubHc of Korea produce PVA and reportedly have an annual production capacity of 50,000 tons (9). 

In 1981, IBM introduced a low cost PC, which provided avenues for access to on-line databases by end users. In 1986 the president of Dialog noted that, although 85% of DIALOG S customers were information speciaHsts or Hbrarians, 80% of new DIALOG accounts were estabHshed for end users (18,19). Users wanted the on-line industry to accommodate their needs and expectations, but the on-line industry did not recogni2e that the availabiHty of large amounts of on-line information would not, of itself, induce people to use the information. 

If it is not dissolved or trapped, an embolism moving from the lower extremities can be life-threatening. People afflicted with phlebitis are particularly susceptible to this problem. A shape-memory trap has been devised that, when deployed in the vena cava, is like a multileaved mesh that traps a traveling embolism, retaining it until medication can dissolve it. Introduced in a folded form by a catheter, the mesh is prevented from deploying by subjecting it to a flow of cold saline water. Once in place, it is released from the catheter and, warmed by body heat, opens into its final shape (11). 

Most accidents do not occur because we do not know how to prevent them but because we do not use the information that is available. The recommendations made after an accident are forgotten when the people involved have left the plant the procedures they introduced are allowed to lapse, the equipment they installed is no longer used, and the accident happens again. The following actions can prevent or reduce this loss of information. 

We put a lot of effort into improving safety by adding protective equipment onto our plants, new and old gas detectors, emergency isolation valves, interlocks, steam curtains, fire insulation, catchment pits for LPG storage tanks, and so on. We also introduced new procedures, such as hazard and operability studies and modification control, or persuaded people to follow old ones, such as permits-to-work and audits. 

An automatic control system is often introduced because it appears to do a job better than the human. However, the human is still asked to monitor its effectiveness. It is difficult to see how the worker can be expected to check in real time that the automatic control system is, for example, using the correct rules when making decisions. It is well known that humans are very poor at passive monitoring tasks where they are required to detect and respond to infrequent signals. These situations, called vigilance tasks, have been studied extensively by applied psychologists (see Warm, 1984). On the basis of this research, it is unlikely that people will be effective in the role of purely monitoring an automated system. 

The somewhat controversial theory of risk homeostasis is relevant to a discussion of risk taking. RHT was developed initially in the area of driving behavior (Wilde, 1984). The theory states that accident rates are not determined by actual levels of intrinsic risk but by the levels of risk acceptable to individuals in the situation. The theory implies that people adjust their risk-taking behavior to maintain a constant level of perceived risk. Thus, if improved safety measures are introduced (e.g., better guarding, improved protection systems then individuals will behave in a more risky fashion in order to maintain their accustomed levels of risk. 

Tlie reader should also note that tlie risk to people can be defined in terms of injury or fatality. The use of injuries as a basis of risk evaluation may be less disturbing tlian tlie use of fatalities. However, tliis introduces problems associated with degree of injury and comparability between different types of injuries. Further complications am arise in a risk assessment when dealing witli multiple hazards. For example, how are second-degree bums, fragment injuries, and injuries due to toxic gas e.xposure combined Even where only one type of effect (e.g., tlueshold to.xic exposure) is being evaluated, different durations of e.xposure can markedly affect tlie severity of injury.

You slide the spoon down and twirl, as opposed to agitating, he said. The whole idea of a martini is a smooth drink. Agitation introduces air. Mr. Conti added, People say you bruise the liquor. I don t believe that—but it is a different texture. ... 

If they were to account for the spectrum of atomic hydrogen and then atoms of the other elements, scientists of the early twentieth century had to revise the nineteenth-century description of matter to take into account wave-particle duality. One of the first people to formulate a successful theory (in 1927) was the Austrian scientist Erwin Schrodinger (Fig. 1.23), who introduced a central concept of quantum theory. 

The Terrestrial Component. These papers illustrate the application of temporal, spatial, and domain connectivity. Chemicals associated with people, food eaten by people, insects, and other organisms that compete with people for food, and other biomass must be identified. Since most of these chemical groups are terrestrial, spatial boundaries such as urban, biome, regional, and global are used. From a system perspective, these boundaries exclude water and air and require that they be placed in the "rest of the system" category. This type of boundary introduces the assumption that food, competitors for food, or any chemical that is discharged to or harvested from the air or water is ignored or assumed to be external to the system studied. 

During the forties and fifties, episodes of severe air pollution occurred In a number of urban and Industrial areas. They were responsible for 111 health and In some cases caused death among the populations concerned. As the scientific and public Information base on the adverse effects of urban air pollution Increased, so did public demand for control measures. As a result, many Industrial countries Introduced comprehensive air pollution control laws at various times from the mid-fifties onwards. Industrial response to these laws led to the application of control techniques which effectively reduced the emissions of some pollutants. However there are other sources and factors which can obscure the benefits of these control actions. For example, consider urban growth. In 1980 there were 35 cities with populations over 4 million. By the year 2000 this number will nearly double to 66, and by the 2025, this number will more than double to an estimated 135 (9). In developing countries, from 1980 to the year 2000, It Is estimated that twice as many people will live In cities of a total population of 1 million or more In Latin America (101 million to 232 million) and East Asia (132 million to 262 million). Three times as many people will live In cities of 1 million or more In South Asia (106 million to 328 million) and four times as many In Africa (36 million to 155 million) (10). Accompanying this rapid growth are Increases In Industrial activity...
