Task requirements

Needfor Achievement. Professionals are often motivated by a need to accomplish complex tasks requiring high levels of skill and effort. Strong commitment is generated when the work is seen as exciting, meaningful, and intellectually challenging. 

Alternative technologies should also be considered, and the reasons for not using them should be justifiable. For example, database technology is not the right choice if a task requires reasoning that goes beyond retrieval of stored data based on well-defined criteria. At the same time, many problems that are stated in a symboHc way can be formulated mathematically, and in fact can be better solved numerically. For such problems, knowledge-based systems are not the appropriate answer. 

Ion-selective electrodes (ISEs) with ionophore-based membranes allow for quantification of a large number of analytes in various matrixes. Tailoring of the composition of the membranes to comply with the analytical task, requires advanced theory of membrane response. Most of theoretical descriptions include nonrealistic extra-thermodynamic assumptions, in the first place it is assumed that some kind of species strongly predominate in membranes. Ideally, a rigorous theory of ISE response should be based on strict thermodynamics. However, real ISE membranes are too complex. Therefore, known attempts aimed at rigorous thermodynamic description of ISEs proved to be fraritless.

Nonemergency medical care should be arranged for hazardous waste site personnel who are experiencing health effects resulting from an exposure to hazardous substances. Off-site medical care should make sure that any potential job-related symptoms or illnesses are evaluated in the context of the employee s exposure. Off-site medical personnel should investigate and treat non-job-related illnesses that may put the employee at risk because of task requirements [1]. 

To manage work means to plan, organize, and control the resources (personnel, financial, and material) and the tasks required to achieve the objective for which the work is needed. 

A simple way to define these is to select one of the priority elements you have identified and brainstorm all of the tasks required to address it, as shown in Figure 5-3.

Project management also influences the likelihood that staffing levels wiU be adequate for the tasks required. This latter factor, together with the extent to which appropriate jobs are assigned to individuals, and the complexity of the jobs, all influence the level of time pressure likely to be felt by the operator. The detailed calculations, which show how the probability of human error is influenced by changes in the sociotechnical factors in the situation, are given in Appendix 5A. 

Tasks required. A summary of the tasks that will be undertaken to achieve the objective, and the roles and responsibilities for each task. 

The team will need to staff tasks by matching skills with task requirements and will need to consider supervision needs for the task teams. 

Avoid tasks requiring mental alertness until response to the drag is known. 

This drug may cause drowsiness, dizziness, and blurring of vision. Use caution when driving or performing tasks requiring alertness. 

Drowsiness—Schedule tasks requiring alertness during times when drowsiness does not occur, such as early in the morning before the first dose of the drug is taken. 

Our laboratory has planned the theoretical approach to those systems and their technological applications from the point of view that as electrochemical systems they have to follow electrochemical theories, but as polymeric materials they have to respond to the models of polymer science. The solution has been to integrate electrochemistry and polymer science.178 This task required the inclusion of the electrode structure inside electrochemical models. Apparently the task would be easier if regular and crystallographic structures were involved, but most of the electrogenerated conducting polymers have an amorphous and cross-linked structure. 

Selection of polymers used in the manufacture of chemical protective clothing (CPC) is a complex task. It involves evaluating breakthrough times and permeation rates in conjunction with such task requirements as tactility and resistance to cuts and abrasion. But, it involves a more basic problem — that of deciding which polymer(s), in the absence of test data, might be most likely to resist permeation by a specific chemical. These decisions are faced not only by users of CPC (e.g., industrial hygienists), but also by poljnner chemists and CPC manufacturers. 

An initial set of Task Requirements and Chemical Attributes is generated by the program from data in the database. When searches are conducted using chemical class, however, all of the chemical attributes are initially recorded as "U" for unknown. These, along with all of the parameters in the Task Requirements segment, can be changed by the user at will. 

The FI function key toggles a help menu in and out of the bottom section of the screen and provides guidance to the user in the specification of valid entries for Task Requirements and Chemical Attributes.

The final physical properties of thermoset polymers depend primarily on the network structure that is developed during cure. Development of improved thermosets has been hampered by the lack of quantitative relationships between polymer variables and final physical properties. The development of a mathematical relationship between formulation and final cure properties is a formidable task requiring detailed characterization of the polymer components, an understanding of the cure chemistry and a model of the cure kinetics, determination of cure process variables (air temperature, heat transfer etc.), a relationship between cure chemistry and network structure, and the existence of a network structure parameter that correlates with physical properties. The lack of availability of easy-to-use network structure models which are applicable to the complex crosslinking systems typical of "real-world" thermosets makes it difficult to develop such correlations.
