Diffusion of innovations

Unless they boil their drinking water, patients who are cured of an infectious disease in a medical clinic Diffusion of innovations return within a short time to be treated again for the same disease.

When Professor Bryce Ryan, fresh from his Ph. Unlike some Diffusion of innovations the previous categories, individuals in this category show little to no opinion leadership. The social model proposed by Ryan and Gross [36] is expanded by Valente who uses social networks as a basis for adopter categorization instead of solely relying on the system-level analysis used by Ryan and Gross.

The norms of a system tell individuals what behavior they are expected to perform. Much of the evidence for this theory, including the adopter categories, did not originate in public health and it was not developed to explicitly apply to adoption of new behaviors or health innovations.

Compatibility - How consistent the innovation is with the values, experiences, and needs of the potential adopters. Typing rhythm is thus facilitated; this hand alternation was achieved by putting the vowels which represent 40 percent of all letters typed on the left-hand side and the major consonants that usually accompany these vowels on the right-hand side of the keyboard.

Such resistance to new ideas is often found in norms on food habits. Direct versus indirect consequences, depending on whether the changes to an individual or to a social system occur in immediate response to an innovation or as a second-order result of the direct consequences of an innovation.

We conceptualize five main steps in the innovation-decision process: The newer arrangement requires less jumping back and forth from row to row.

Research was done in the early s at the University of Chicago attempting to assess the cost-effectiveness of broadcast advertising on the diffusion of new products and services. A communication network consists of interconnected individuals who are linked by patterned flows of information.

The residents had no knowledge of the link between sanitation and illness. The innovation-decision process involves time in the sense that the five steps usually occur in a time-ordered sequence of 1 knowledge, 2 persuasion, 3 decision, 4 implementation, and 5 confirmation.

Diffusion is the process in which an innovation is communicated through certain channels over time among the members of a social system. Newness in an innovation need not just involve new knowledge.

Strategies to appeal to this population include how-to manuals and information sheets on implementation. In this sense opinion leaders are influential in spreading either positive or negative information about an innovation.

Knowing of a technological innovation creates uncertainty about its consequences in the mind of potential adopters. The public reaction to this draconian approach was so negative that the U.

For instance, the steel ax was introduced by missionaries to an Australian aborigine tribe Sharp, Communication is a process in which participants create and share information with one another in order to reach a mutual understanding. Eventually, the trajectory of the rate of adoption begins to level off, as fewer and fewer individuals remain who have not yet adopted the innovation.

Exceptions to the usual sequence of these five stages may occur for some individuals under some conditions, such as when the decision stage precedes the persuasion stage perhaps an individual was ordered to adopt by some authority figure. Most can tolerate cooked water only if a flavoring, such as sugar, lemon, or herbs, is added.

The three sources of water in Los Molinas include a seasonal irrigation ditch close to the village, a spring more than a mile away from the village, and a public well whose water most villagers dislike. The adoption of an innovation follows an S curve when plotted over a length of time.

Opinion leaders may begin to be perceived by their peers as too much like professional change agents and therefore lose their credibility with their former followers.

Diffusion theories can never account for all variables, and therefore might miss critical predictors of adoption. Indirect costs may also be social, such as social conflict caused by innovation. In addition to the so-called miracle varieties of rice or wheat, the cluster included chemical fertilizers, pesticides, and thicker planting of seeds.

Certain other members of the system function as opinion leaders. Villagers learn from early childhood to dislike boiled water.

Change agents bring innovations to new communities— first through the gatekeepers, then through the opinion leaders, and so on through the community.

Presumably the two recycling behaviors represent two innovations that are part of an interrelated cluster of several recycling ideas. The campaign worked with the villagers to try to teach them to boil water, burn their garbage, install latrines and report cases of illness to local health agencies.

It works better with adoption of behaviors rather than cessation or prevention of behaviors. Boiled water and illness are closely linked in the norms of Los Molinas. Compatibility is the degree to which an innovation is perceived as being consistent with the existing values, past experiences, and needs of potential adopters.

Observability - The extent to which the innovation provides tangible results. People tend to be close to others of similar health status.The process evaluation was primarily based on Rogers's diffusion of innova- tions model, including monitoring of the intervention delivery, participation, comprehension, satisfaction, level of use.

The idea suggests that, for good or bad, change can be promoted rather easily in a social system through a domino effect. Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread.
