The conduction and convection heat transfer in engines are processes that occur in series and parallel with each other. A series path is convection through the cylinder gas boundary layer, conduction across the cylinder wall, and convection through the coolant liquid boundary layer; and a parallel path is conduction through the cylinder wall and through the piston crown. In heat transfer resistance modeling, we look for regions which have relatively large temperature differences, and compute the heat transfer resistance across those regions. The thermal resistance is defined as the ratio of the temperature difference, dT, to the heat transfer Q. The resistance model is very useful in determining the heat transfer in a complex steady state heat transfer situation.

Sheth and ACR reviewers for their comments and suggestions on an earlier draft of this manuscript. In fact, this restricted view extends across the numerous disciplines that have examined the innovation process: rural sociology Rogers, , geography Brown, The chief reason for this has been the "pro- innovation bias" of researchers Rogers. If this were indeed true. The problem has been compounded by the fact that.
Innovations impose change on the consumer. Some scholars have, thus, suggested that viewing innovations from the adoption and diffusion perspectives should be de-emphasized, and studying the process of innovation resistance must be given attention: ". Adoption begins only after the initial resistance offered by the consumers is overcome. Thus, it is the Resistance perspective which looks at what happens to the innovation since the time it is conceived.
If the resistance is too high. Hence, it is quite important that innovation resistance per se is studied.
The objective of this paper is to develop a model of innovation resistance. At a very general level, an innovation has been defined as an " From a marketer's point of view. This perceived newness may be due to change s in just one attribute of the product e. A firm may come up with an "intended" innovation - however.
The lack of adoption. Addressing the causes for and solutions to this problem is beyond the scope of this paper. What emerges from the foregoing discussion, however. Yet, every product in the market will be a potential innovation for consumers who perceive it to be so.
It is from this perspective that the study of innovation resistance has been approached here. Innovation Resistance is the resistance offered by consumers to changes imposed by innovations. To the extent that consumers can suffer changes in the way they acquire information about. Several theories in psychology explicitly deal with resistance to change Newcomb. All these theories suggest that consumers have an intrinsic desire for psychological equilibrium. In other words.
Based on past literature, the Innovation Resistance of a consumer can be viewed as dependent on three sets of factors: Perceived Innovation Characteristics. Consumer Characteristics. If the consumer perceives a high degree of change in using the innovation. If the innovation encounters consumer resistance, then it needs to be modified by the firm to suit consumer needs and reduce the resistance. The modification to be made would depend on what caused the resistance: if the resistance vas due to lack of compatibility.
If the innovation cannot be modified. If it can be modified. The cycle is repeated leading to ultimate acceptance or failure of the innovation. The model of Innovation Resistance is set in the contest of Cultural, Situational and Social factors, since a variation in each of these can affect Resistance. The impact of these factors is not addressed in this paper.
Let us now examine how each of the three major groups of factors - Perceived Innovation Characteristics, Consumer Characteristics, and Characteristics of Propagation Mechanisms affect Innovation Resistance. The characteristics of an innovation, as perceived by the consumer, determine the amount of resistance generated. The costs that are saved could be either financial, such as investment costs. The innovation could also provide improved performance at comparatively lower costs - in other words, higher "value.
Compatibility of an innovation is " Extending this definition, compatibility represents not only consistency with the existing values of the consumer, but also with traditional and cultural values, and with current lifestyles of the consumer. Linked to compatibility is the notion of pervasiveness. Pervasiveness of an innovation is the degree to which it relates to and requires changes or adjustments on the part of the consumer Barnett, P2: The lower the perceived compatibility or higher the pervasiveness of an innovation, the higher the innovation resistance.
Perceived Risk is the risk associated with adopting the innovation, and can be of several types: physical risk, functional risk performance uncertainty , psychological risk and social risk. The level of perceived risk depends on the type of innovation. P3: The higher the levels of any of the perceived risk components physical, functional, psychological or social , the higher the innovation resistance. Trialability of an innovation relates to how easily the innovation can be tried by the consumer prior to adoption, and impacts on the perceived risk associated with the innovation.
If, for instance. Related to trialability is the concept of divisibility of the innovation. P4: The lower the trialability of an innovation, the higher the innovation resistance. P5: The lower the divisibility of an innovation, the higher the innovation resistance. In the contest of innovations, this would imply the ease with which the benefits of the product can be conveyed to the consumer.
Communicability has two components: tangibility of the benefits from adopting the innovation, and ability of the marketer to communicate the benefits.
If either or both of these components is lacking, then the innovation is likely to meet with high resistance. P6: The lower the communicability of an innovation, the higher the innovation resistance.
The complexity of an innovation arises from two dimensions: complexity of the idea is it easy to understand? Complexity has to be reduced on both these dimensions for the consumer. P7: The higher the complexity of an innovation, the higher the innovation resistance.
Zaltman et. Reversibility denotes the option that a consumer may have in terms of being able to discontinue adoption of the innovation at least temporarily , if 80 desired. P8: The lower the reversibility of an innovation, the higher the innovation resistance. Realization is how soon the consumer expects to receive the benefits from the innovation. P9: The lower the realization of an innovation, the higher the innovation resistance.
Amenability to Modification reflects the flexibility with which the innovation can be modified to ensure consumer satisfaction. If innovation modification is not feasible, the innovation may be rejected immediately.
P The lower the amenability to modification of an innovation, the higher the innovation resistance. In some cases, the adoption of one innovation may have an inhibitory effect on the adoption of other profitable innovations. If this were the case, the consumer may opt out of the problematic innovation. P The higher the inhibitory effect of an innovation on the adoption of other beneficial innovations, the higher the consumer resistance to this innovation.
According to them. These factors can be expected to create the same type of resistance across all consumers. Compatibility etc. An innovation is newness as perceived by the consumer. Thus, the resistance to an innovation is dependent on the psychological characteristics of the consumer. Some of the factors that have been identified as relevant to consumer behavior in the context of innovations are: Personality, Attitudes.
Value Orientation. Of these factors. Unless the consumer perceives the need for the innovation. P The higher the consumer's perceived lack of need for the product. A second source of resistance is consumer motivation. Behaviors that are comfortable. If the consumer is quite content with the current routine.
The consumer's personality is a major determinant of innovation resistance. For instance. Personality traits such as self-confidence and dogmatism play an important role in how consumers react to innovations.
For example, in the case of innovations which cannot be tested prior to purchase. Similarly, based on the dogmatism scale developed by Rokeach P The lower the consumer's self-confidence.
P The higher the consumer's dogmatism. The consumer's attitudes and beliefs determine the amount of resistance that he offers to an innovation. For example. The Previous Innovative Experience of a consumer also affects innovation resistance.
The biasing influence of past experience that-an individual brings to a present problem-solving or decision-making activity is known as "mind set. Thus far. These characteristics reflect the consumer's Willingness to Innovate. The consumer characteristics which affect the consumer's ability to innovate are the demographic variables such as Education.
Mobility and Age.
Some may argue that not having sufficient data to parameterize a mechanistic model is a reason to ignore such a mechanism in a model analysis. However, if they are openly supportive of and advocating for a particular change, these behaviors will also show up in how employees react to the change. So, don't introduce change believing that you will experience nothing but resistance or that resistance will be severe. They may prefer the status quo.
