What does the media mean?

Media refers to the external factors that can help pathogens infect susceptible animals indirectly after they are discharged from the source of infection. In the chicken epidemic, most infectious diseases and parasitic diseases are spread through the media. Among them, the main media are as follows:

(1) Feed and drinking water are contaminated by pathogens.

Newcastle disease and salmonellosis are mainly transmitted through feed and drinking water contaminated by sick chickens. Therefore, during the epidemic period of infectious diseases, it is necessary to disinfect the management equipment, barns and feed warehouses of chicken farms.

(2) padding and feces

When chickens get sick, a large number of pathogens are discharged from feces, which pollutes padding and can be used as feed and drinking water in secondary pollutants, thus spreading diseases. Therefore, chicken manure must be cleaned up in time, the padding should be replaced in time and disinfected regularly.

(3) Air (droplets, dust, etc. )

Chickens spray droplets when they cough and crow. These droplets stained with viruses and bacteria can float in the air for a long time, and healthy chickens can be infected after inhalation. Dust with pathogens floating in the air can also spread chicken diseases. Generally speaking, a dry, bright, warm and well-ventilated henhouse environment can reduce the spread of chicken diseases.

(4) Contaminated eggs

Eggs are a special carrier for spreading chicken infectious diseases. Known infectious diseases spread by eggs mainly include colibacillosis, typhoid fever, paratyphoid fever, pullorum disease, mycoplasma disease, viral arthritis and egg drop syndrome. Chickens suffering from the above-mentioned chicken diseases have pathogens in their ovaries and fallopian tubes, which enter the eggs during the formation of eggs. If these eggs hatch, they will make the chickens sick or even die.

(5) Polluted feathers and dander

Chicken villi and feathers are easily polluted by feces, infected with bacteria or viruses, and spread and float in the henhouse, which will make chicks infected with respiratory diseases. In addition, feathers and dander are also the main vectors of Marek's disease in chickens.

(6) People and animals walk, blood-sucking insects, etc.

Humans and other animals (flies, mosquitoes, midges, flies, mice, etc. ) It can also spread chicken diseases. If breeders and veterinarians do not pay attention to disinfection in their work, they may spread pathogens contaminated on their hands, clothes and soles to healthy chickens when they enter and leave sick chicken houses and healthy chicken houses, which will become one of the main reasons for the outbreak of infectious diseases.

What does the media mean? Is it similar to the media?

Media is a basic title, which refers to the intermediary between information source and information receiver. It can be a person, an institution, or an object that can transmit information, such as a small piece of paper.

Besides the significance of the media, it is more important to emphasize its materiality. For example, television, radio, newspapers and the Internet are the four major media today, and some people understand it as a comprehensive application of various modes of communication such as multimedia.

In fact, media is the abbreviation of media, but now it has its specific meaning, which represents the highest realm of communication, mass communication. They have turned some channels of obtaining information in our lives into media organizations, such as newspapers and radio stations.

Extended data:

Media includes two elements:

One is the container containing the information or content carried by the media, such as books (Oracle Bone Inscriptions, bamboo slips, silk books, paper books), photos, audio tapes, film, video tapes, audio-visual discs, etc.

The second is the technical equipment, organizational form or social mechanism used to spread information, including communication (post horse, telegraph, telephone, fax, e-mail, videophone, mobile phone, etc. ), radio (announcements, newspapers, magazines, radio, television, etc. ) and the network.

In contemporary society, generally speaking, the media refers to mechanically printed books, newspapers, magazines, radio, television and the Internet. They are all mass communication tools used to spread news or influence public opinion, and they are all media for spreading information.

The four traditional media are television, radio, newspapers and weekly magazines. In addition, there must be outdoor media, such as advertising space for street sign light boxes.

With the development of science and technology, new media such as Internet TV and electronic magazines have gradually appeared. They are developed on the basis of traditional media, but they are qualitatively different from traditional media.

CCITT divides the media into five categories:

(1) Perceptual medium: refers to the medium that directly acts on human sensory organs and makes people feel directly. For example, sounds that cause auditory reactions, images that cause visual reactions, and the like.

(2) Performance media: refers to the intermediary media that transmits the sensory media, that is, the code used for data exchange. Such as image coding (JPEG, MPEG, etc. ), text coding (ASCII code, GB23 12, etc. ) and voice coding.

(3) Presentation media: refers to the media for information input and output. Such as keyboard, mouse, scanner, microphone, camera, etc. As an input medium; Monitors, printers, speakers, etc. It's an output medium.

(4) Storage media: refers to the physical media used to store the presentation media. Such as hard disk, floppy disk, magnetic disk, optical disk, ROM and RAM.

(5) Tran * * * issue medium: refers to the physical medium of the transmission medium. Such as cables and optical cables.

What we usually call "media" includes two meanings.

One refers to the physical carrier of information (that is, the entity that stores and transmits information), such as books, wall charts, disks, optical disks, tapes and related playback equipment; Another meaning refers to the expression (or communication) form of information, such as words, sounds, images, animations, etc.

The medium mentioned by multimedia computer refers to the latter, that is, the computer can not only process information such as words and values, but also process various forms of information such as sound, graphics and TV images.

Among them, the word "media" refers to the matchmaker in the pre-Qin period, and later extended to the cause. Poetry Feng Wei Mang: "When I was robbed, I had no good media."

Wen Zi Wei Xiang: "Those who are happy at the sight of fame are also the media." The word "intermediary" always refers to the intermediary or tool between the two.

It also refers to an activity or organization that expresses an action state between two or more people or things.

Interpretation of media meaning

The word "media" first appeared in the biography of Zhang Xing in the Old Tang Dynasty: "The opinions of employing people in ancient and modern times must be based on media." The "medium" here refers to the person or thing that indicates both parties. Among them, the word "media" refers to the matchmaker in the pre-Qin period, and later extended to the cause. Poem Feng Wei Mang: "When I was robbed, I had no good media." Wen Zi Wei Xiang: "Those who are happy at the sight of fame are also the media." The word "intermediary" always refers to the intermediary or tool between the two.

In English, the medium "media" is the plural form of "medium", which appeared at the end of 19 and the beginning of the 20th century, and its meaning is the medium or tool for directing things. This kind of generalized "media" is not only heard from time to time in human daily life (such as "mosquitoes are the media to spread diseases" and "hydrangeas are the media to convey love"), but also common in communication works. According to M. Meluhan (1964), media is everything, everything is media, and all media can have some connection with human body. For example, a stone axe is an extension of hands, wheels are an extension of feet, books are an extension of eyes, broadcasting is an extension of ears, and clothes are an extension of skin. The media is everywhere. Any substance that can make people contact or * * * with people, people and things or things is a generalized medium.

Even in a narrow sense, people's understanding and application of "media" are different and quite confusing. Sometimes it is confused with symbols: "Media refers to the physical form that carries and transmits information, including physical entities and physical energy. The former includes characters, various printed materials, marks, symbolic objects, information dissemination equipment, etc. The latter are sound waves, light, radio waves, etc. " (Gong Wei, 1988) is sometimes confused with forms of communication: "Media is a simple and convenient term, which is usually used to refer to all forms of information communication with a wide range of communication objects, including movies, television, radio, newspapers, popular literature, music, etc." (Barit, 1986) is sometimes confused with channels and news: "Strictly speaking, the media is channels-spoken words, printed words and so on. However, this term is often used to refer to channels and sources, and sometimes even includes information. " "When we talk about' mass media', we often refer not only to the channels of mass communication, but also to the content of these channels, and even to the behavior of people working for these channels." (David Sandeman, etc. 199 1) We believe that the confusion of media concept will lead to the confusion of discussion, and the confusion of discussion will inevitably lead to the confusion of theory and cannot guide the practice of communication. Therefore, the concept of media must be clarified and positioned.

Media expansion

2. The difference between media and communication symbols, forms and channels.

Media is different from communication symbols. Symbols refer to codes (such as language, characters, images, etc.). ) indicates or carries specific information or meaning, and the medium refers to the material entity that carries, expands, extends and transmits specific symbols between the sender and the receiver. As a kind of code or means, symbol reflects the process of people's understanding of things and the logical characteristics of information expression, so it often has the characteristics of abstraction, order, thinking and consciousness. As a material entity, media reflects the characteristics and existing forms of matter and energy, such as hard stone tablets, light and soft paper, rough speakers and exquisite TV sets ... they all have shapes, weights and sizes and can be moved, preserved and destroyed. The relationship between information and symbols, symbols and media is just like the relationship between hair and skin. If the skin does not exist, how can the hair be attached?

(2) The media is different from the form of communication. The form of communication refers to the specific ways in which the communicator acts on the audience, such as oral communication, written communication, image communication and comprehensive communication. In political communication, people are used to literary forms, musical forms, reminiscing about bitter experiences and visiting forms. In the form of written communication, people can use books, newspapers, magazines, leaflets, brochures and other media to spread information. A form of communication can use different media, and a medium can also serve different forms. For example, television can display this function. But the form of communication only shows the state, mode and structure of communication activities, while the media shows the real objects.

(3) Media is different from communication channels. The word "Channel" in English originally means waterway, waterway, route, access road, gateway, passage and so on. In communication science, it refers to various channels of communication and information exchange between the two sides, such as interpersonal communication channels, organizational communication channels, mass communication channels and so on. Different communication channels need different media cooperation, and different media shape different communication channels. For example, interpersonal communication channel is face-to-face communication between people, which determines that only human organ media (such as communication media-mouth, receiving media-ears) and air media can be used. However, once information is spread through radio and television, it is also a mass communication channel. Interpersonal media can enter all kinds of communication channels at will, and cooperate with specific media without changing their channel forms, while mass media is completely different. It can be seen that the media is not equal to the communication channel.

Meaning itself refers to the person or thing borrowed by both parties.

In the sense of communication, it refers to a material tool that uses the media to store and disseminate information. Shi Lamu, a famous American communication scientist, believes that "media is a tool to expand and extend information transmission in the process of communication", and at the same time, "media" has also become a position, such as media specialist, media planning, commercial media and so on.

This medium includes two elements:

One is the container containing the information or content carried by the media, such as books (Oracle Bone Inscriptions, bamboo slips, silk books, paper books), photos, audio tapes, film, video tapes, audio-visual discs, etc.

The second is the technical equipment, organizational form or social mechanism used to spread information, including communication (post horse, telegraph, telephone, fax, e-mail, videophone, mobile phone, etc. ), radio (announcements, newspapers, magazines, radio, television, etc. ) and the network.
