Rogers' Diffusion and Adoption Research Why do technology initiatives fail despite their promises and boundless possibilities? From integrating technology in education to introducing technological innovation in agriculture, users acceptance presents a complex set of challenges to innovation diffusion. According to Everett Rogers, one reason why there is so much interest in the diffusion of innovations is because "getting a new idea adopted, even when it has obvious advantages, is very difficult" (Rogers, 1995, p. 1). In the instructional technology field, the rapid advances in information technology urges on the educational reform. This reform created a need for more research in the educational application of technology as well as in the adoption and diffusion of instructional technology. According to Surry (1995), there are three reasons why the study of diffusion theory is beneficial to the field of instructional technology. First, most instructional technologists lack the knowledge of why their products are or are not adopted. Surry (1995) believes a study of diffusion theory could rectify this situation. Second, the field of instructional technology is often associated with the concept of innovations. Surry (1995) suggested that if instructional technologists understand the adoption and diffusion of innovation theory, they will be more prepared to work effectively with potential adopters. Third, Surry (1995) concluded the studies of the diffusion theory could result in developing a systematic model of adoption and diffusion for the instructional technology field. As instructional technologists, not only do we need to create well-designed products, we need to ensure the adoption of these produc... ... middle of paper ... ... instructional technology. In G.J.

Dr. John Abramson’s book Overdosed America debunks the myths about the excellence of American medicine. Abramson backs up this claim by closely examining research about medicine, closely examining the unpublished details submitted by drug manufacturers to the FDA, and discovering that the unpublished data does not coincide with the claims made about the safety and effectiveness of commonly used medicines. Abramsons purpose is to point out the flaws of the pharmaceutical industry in order to warn the readers about the credibility of the drugs they are buying. Given the critical yet technical language of the book, Abramson is writing to an audience that may include academic physicians as well as those who want to learn about the corruption of the pharmaceutical industry.

However, it is interesting how contradictory the finding is to several other claims. Studies have shown that serotonin, in normal levels, exerts a calming, inhibitory effect on neuronal firing (5) and that, in low levels of serotonin, aggressive and impulse behaviors increase (6).This contradicts the previous claim that a built-up, or high levels of serotonin caused by the MAOA mutation, causes violent behavior.
Of the chemical neurotransmitter substances, serotonin is perhaps the most implicated in the treatment of various disorders, including anxiety, depression, obsessive-compulsive disorder, schizophrenia, stroke, obesity, pain, hypertension, vascular disorders, migraine, and nausea. A major factor in the understanding of the role of 5-HT in these disorders is the recent rapid advance made i...

"The emergence of the basic paradigm for early diffusion research [was] created by two rural sociologists at Iowa State University, Bryce Ryan and Neal C. Gross" and gained recognition when they "published the results of their hybrid corn study"(Valente and Rogers, 1995, paragraph 1 ) in 1943. Post World War II agriculture experienced a boom in "technological innovation" and "as a result…U.S. farms became business enterprises rather than family-subsistence units…concerned with productivity, efficiency, competitiveness, and agricultural innovations"(Valente and Rogers, 1995, paragraph 11 ). These concerns lead to many agricultural studies based on the diffusion paradigm developed by Ryan and Gross. In their studies, Ryan and Gross were able to show that diffusion was a "social process through which subjective evaluations of an innovation spread from earlier to later adopters rather than one of rational, economic decision making" (Valente and Rogers, 1995, paragraph 22 ). From this they developed the paradigm for diffusion research, consisting of four parts: "(1) the innovation-decision process for an individual farmer, including the sequential stages of awareness, trial, and adoption; (2) the roles of information sources/channels about the innovation; (3) the S-shaped rate of adoption, a curve that was tested as to whether it fit a normal distribution; and (4) the personal, economic, and social characteristics of various adopter categories (i.e., classification of individuals on the basis of their relative earliness in adopting an innovation)"(Valente and Rogers, 1995, paragraph 23) Gabriel Tarde, a French sociologist in the early 1900s, "identified the S-shaped curve of the rate of adoption of an inno...

Why do some innovations get adopted while others fail? The diffusion theory offers up one explanation for this phenomenon. The theory can be applied to a multitude of different products or ideas. This theoretical approach is fascinating do to the breadth of different fields that it can be applied to and to the depth that it can go into the field to formulate a. It allows for people to formulate a better understanding of the spread of new innovations. Diffusion theory can give a comprehensive picture as to how ideas spread in this social media age. To understand the depth of the diffusion of innovation theory you have to first understand what the theory is and how it analyzes situations. Then it has to be applied to and utilized. Lastly the justification of why this theory is an appropriate fit for the selected field of interest. The study of diffusion has been pursued by many scholars dating back over a hundred years.
Diffusion of Innovation (DOI) Theory, developed by Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product spreads through a specific population or social system. The end result of this diffusion is that people, as part of a social system, adopt a new idea, behavior, or product. Adoption means that a person does something differently than what they had previously. The key to adoption is that the person must perceive the idea, behavior, or product as new or innovative. It is through this that diffusion is possible (Boston University of Public Health, 2013).
The increase of addiction to prescription drugs has increased over the past few years. As a result the amount of pharmacy robberies has amplified as well. Certain patients are going to multiple physicians in order to get controlled prescriptions; this is called “doctor shopping.” They are then filling the prescriptions at different pharmacies by paying “out of pocket,” without insurance. Filling prescriptions without insurance and at different pharmacies allows patients to get the medications more frequently. Insurance companies usually limit people from filling prescriptions early (before their medication runs out). It has been too simple to get control prescriptions from doctors in this day and age. Physicians have been arrested for writing narcotic prescriptions unnecessarily and too easily. Some patients even steal prescription pads from the doctor’s offices, in order to write their own prescriptions for controlled medications. It is the pharmacist’s role to spot these “fake” prescriptions. This is a vicious cycle and it needs to be stopped.
High Scope promotes the developmental domains in their Key Developmental Indicators (KDIs). KDIs break down the developmental domains, and it talks about how they can be incorporated in the curriculum. Cognitive development is promoted through their children exploring objects through their five senses, exploring similarities and different in on things in the environment, one to one correspondence, numbers, Seeing things form different perspectives, time intervals, and cause and effect. High Scope also promotes Cognitive development through their large and small group times. Social and emotional developments are promoted through teacher- child interactions, child- child interactions through play, group participation, children forming attachments to primary care teacher, and children distinguishing themselves from other. The KDIs helps as a tool for teachers to help promote positive and strong relationships with adults and children. KDIs also help promote physical development through movement abilities, fitness, and healthy behavior in the classroom. High Scope helps to...
Polymorphisms of the 5-HT2a receptor gene have been implicated as a minor risk factor for developing schizophrenia (Steeds, 2015). Additionally, a loss of PFC 5-HT2a receptors accompanied by an increase in 5-HT1a receptors and a blunted neuroendocrine response to 5-HT2a agonists (Eggers, 2013, Millan, 2000) have been seen in schizophrenia. Finally, the high affinity of atypical antipsychotic medications such as clozapine for the 5-HT2a receptor further supports the role of the 5-HT serotonergic systems in schizophrenia (Eggers, 2013).
The “Farm-to-Fork movement” as it is called in some circles aspires to have farmers produce and sell the food as they have for centuries – through natural processes that don’t negatively impact the environment. The result, say advocates, is a better earth, nourishing food and healthier people. The choice of natural and organic food is evidenced by the huge spike in sales by warehouse retailer Costco (Gonzalez). The Washington-based company recently surpassed Whole Foods Market as the number one purveyor of organic foods in the United States (Gonzalez). Costco is projected to make $4 billion in sales of organic products this year, representing more than 1 out of 10 dollars in the organic food sales market (Gonzalez). The Organic Trade Association, an industry group, estimates total organic-food sales in the U.S. to be around $36 billion (Gonzalez). These numbers indicate that the natural food movement cannot be ignored. With that in mind, how will the earth continue to feed itself? The answer is not an easy one. There will be many solutions, spewed by politicians, farmers, scientists and ordinary people. Whatever the answer, it is clear that the world’s people need to change course. Old habits need to be adjusted, from the voracious consumption of meat to the addiction to processed foods like soda. The world will need to find its way back to nature, back to the roots of the land that had sustained people for centuries
