Information Deficit Model
In studies of the public understanding of science, the information deficit model (or simply deficit model) or science literacy/knowledge deficit model attributes public scepticism or hostility to science and technology to a lack of understanding, resulting from a lack of information. It is associated with a division between experts who have the information and non-experts who do not. The model implies that communication should focus on improving the transfer of information from experts to non-experts. The model has been repeatedly challenged by science communication researchers. For example, in climate communication, even though today the majority of peoples worldwide believe climate change is a global emergency, climate action has been impeded by other factors, such as political opposition, corruption and oil company interest. Deficit model of science communication The original term 'deficit model' was coined in the 1980s by social scientists studying the public communication of ...

Public Understanding Of Science
Public awareness of science (PAwS) is everything relating to the awareness, attitudes, behaviors, opinions, and activities that comprise the relations between the general public or lay society as a whole to scientific knowledge and organization. This concept is also known as public understanding of science (PUS), or more recently, public engagement with science and technology (PEST). It is a comparatively new approach to the task of exploring the multitude of relations and linkages science, technology, and innovation have among the general public. While early work in the discipline focused on increasing or augmenting the public's knowledge of scientific topics, in line with the information deficit model of science communication, the deficit model has largely been abandoned by science communication researchers. Instead, there is an increasing emphasis on understanding how the public chooses to use scientific knowledge and on the development of interfaces to mediate between expert ...

Biotechnology
Biotechnology is the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts thereof and molecular analogues for products and services. The term ''biotechnology'' was first used by Károly Ereky in 1919, meaning the production of products from raw materials with the aid of living organisms. Definition The concept of biotechnology encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materia ...

Thinking, Fast And Slow
''Thinking, Fast and Slow'' is a 2011 book by psychologist Daniel Kahneman. The book's main thesis is a differentiation between two modes of thought: "System 1" is fast, instinctive and emotional; "System 2" is slower, more deliberative, and more logical. The book delineates rational and non-rational motivations or triggers associated with each type of thinking process, and how they complement each other, starting with Kahneman's own research on loss aversion. From framing choices to people's tendency to replace a difficult question with one which is easy to answer, the book summarizes several decades of research to suggest that people have too much confidence in human judgement. Kahneman performed his own research, often in collaboration with Amos Tversky, which enriched his experience to write the book. It covers different phases of his career: his early work concerning cognitive biases, his work on prospect theory and happiness, and with the Israel Defense Forces. The book ...

Low-information Rationality
In psychology, the human mind is considered to be a cognitive miser due to the tendency of humans to think and solve problems in simpler and less effortful ways rather than in more sophisticated and effortful ways, regardless of intelligence. See also other chapters in the same book: "Framing and the cognitive miser" (chapter 7); "A different pitfall of the cognitive miser: thinking a lot, but losing" (chapter 9). Just as a miser seeks to avoid spending money, the human mind often seeks to avoid spending cognitive effort. The cognitive miser theory is an umbrella theory of cognition that brings together previous research on heuristics and attributional biases to explain when and why people are cognitive misers. The term ''cognitive miser'' was first introduced by Susan Fiske and Shelley Taylor in 1984. It is an important concept in social cognition theory and has been influential in other social sciences such as economics and political science. Assumption The metaphor of the c ...

Cultural Cognition
The cultural cognition of risk, sometimes called simply cultural cognition, is the hypothesized tendency to perceive risks and related facts in relation to personal values. Research examining this phenomenon draws on a variety of social science disciplines including psychology, anthropology, political science, sociology, and communications. The stated objectives of this research are both to understand how values shape political conflict over facts (like whether climate change exists, whether gun control increases crime, whether vaccination of school girls for HPV threatens their health) and to promote effective deliberative strategies for resolving such conflicts consistent with sound empirical data. Theory and evidence The ''cultural cognition hypothesis'' holds that individuals are motivated by a variety of psychological processes to form beliefs about putatively dangerous activities that match their cultural evaluations of them. Persons who subscribe to relatively individualisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Food Safety-risk Analysis
A food safety-risk analysis is essential not only to produce or manufacture high quality goods and products to ensure safety and protect public health, but also to comply with international and national standards and market regulations. With risk analyses food safety systems can be strengthened and food-borne illnesses can be reduced. Food safety risk analyses focus on major safety concerns in manufacturing premises—not every safety issue requires a formal risk analysis. Sometimes, especially for complex or controversial analyses, regular staff is supported by independent consultants. Risk analysis Risk analysis is defined for the purposes of the Codex Alimentarius Commission as "A process consisting of three components: risk management, risk assessment, and risk communication." About Risk Analysis in Food. World Health Org ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Framing (social Sciences)
In the social sciences, framing comprises a set of concepts and theoretical perspectives on how individuals, groups, and societies organize, perceive, and communicate about reality. Framing can manifest in thought or interpersonal communication. ''Frames in thought'' consist of the mental representations, interpretations, and simplifications of reality. ''Frames in communication'' consist of the communication of frames between different actors. Framing is a key component of sociology, the study of social interaction among humans. Framing is an integral part of conveying and processing data on a daily basis. Successful framing techniques can be used to reduce the ambiguity of intangible topics by contextualizing the information in such a way that recipients can connect to what they already know. In social theory, framing is a schema of interpretation, a collection of anecdotes and stereotypes, that individuals rely on to understand and respond to events. Goffman, E. (1974) ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causin ...
