Communication
Communication is usually defined as the transmission of information. The term can also refer to the message itself, or the field of inquiry studying these transmissions, also known as communication studies. There are some disagreements about the precise definition of communication - for example, whether unintentional or failed transmissions are also included and whether communication does not just transmit meaning but also create it. Models of communication aim to provide a simplified overview of its main components and their interaction. Many models include the idea that a source uses a coding system to express information in the form of a message. The source uses a channel to send the message to a receiver who has to decode it in order to understand its meaning. Channels are usually discussed in terms of the senses used to perceive the message, like hearing, sight, smell, touch, and taste. Communication can be classified based on whether information is exchanged between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sign Language
Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutually intelligible, although there are also similarities among different sign languages. Linguists consider both spoken and signed communication to be types of natural language, meaning that both emerged through an abstract, protracted aging process and evolved over time without meticulous planning. Sign language should not be confused with body language, a type of nonverbal communication. Wherever communities of deaf people exist, sign languages have developed as useful means of communication and form the core of local Deaf cultures. Although signing is used primarily by the deaf and hard of hearing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communication Studies
Communication studies or communication science is an academic discipline that deals with processes of human communication and behavior, patterns of communication in interpersonal relationships, social interactions and communication in different cultures. Communication is commonly defined as giving, receiving or exchanging ideas, information, signals or messages through appropriate media, enabling individuals or groups to persuade, to seek information, to give information or to express emotions effectively. Communication studies is a social science that uses various methods of empirical investigation and critical analysis to develop a body of knowledge that encompasses a range of topics, from face-to-face conversation at a level of individual agency and interaction to social and cultural communication systems at a macro level. Scholarly communication theorists focus primarily on refining the theoretical understanding of communication, examining statistics in order to help subs ...

Human Communication
Human communication, or anthroposemiotics, is a field of study dedicated to understanding how humans Communication, communicate. Humans ability to communicate with one another would not be possible without an understanding of what we are referencing or thinking about. Because humans are unable to fully understand one another's perspective, there needs to be a creation of commonality through a shared mindset or viewpoint. The field of communication is very diverse, as there are multiple layers of what communication is and how we use its different features as human beings. Humans have communicatory abilities other animals do not, for example, humans are able to communicate about time and place as though they are solid objects. Humans communicate to request help, to inform others, and to share attitudes for bonding. Communication is a joint activity largely dependent on the ability to maintain common attention. We share relevant background knowledge and joint experience in order to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Languages
Artificial languages are languages of a typically very limited size which emerge either in computer simulations between artificial agents, robot interactions or controlled psychological experiments with humans. They are different from both constructed languages and formal languages in that they have been consciously devised by an individual or group but are the result of (distributed) conventionalisation processes, much like natural languages. Opposed to the idea of a central ''designer'', the field of artificial language evolution in which artificial languages are studied can be regarded as a sub-part of the more general cultural evolution studies. Origin The idea of creation of artificial language arose in 17th and 18th century as a result of gradually decreasing international role of Latin. The initial schemes were mainly aimed at the development of a rational language free from inconsistence of living language and based on classification of concepts. The material of living la ...

Cell Wall
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are absent in many eukaryotes, including animals, but are present in some other ones like fungi, algae and plants, and in most prokaryotes (except mollicute bacteria). A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters. The composition of cell walls varies between taxonomic group and species and may depend on cell type and developmental stage. The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses and pectin. Often, other polymers such as lignin, suberin or cutin are anchored to or embedded in plant cell walls. Algae possess cell walls made of glycoproteins and polysaccharides such as carrageenan and agar that are absent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bees
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are presently considered a clade, called Anthophila. There are over 16,000 known species of bees in seven recognized biological families. Some speciesincluding honey bees, bumblebees, and stingless beeslive socially in colonies while most species (>90%)including mason bees, carpenter bees, leafcutter bees, and sweat beesare solitary. Bees are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. The most common bees in the Northern Hemisphere are the Halictidae, or sweat bees, but they are small and often mistaken for wasps or flies. Bees range in size from tiny stingless bee species, whose workers are less than long, to ''Megachile pluto'', the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waggle Dance
Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new nest-site locations with other members of the colony. The waggle dance and the round dance are two forms of dance behaviour that are part of a continuous transition. As the distance between the resource and the hive increases, the round dance transforms into variations of a transitional dance, which, when communicating resources at even greater distances, becomes the waggle dance. In the case of ''Apis mellifera ligustica'', the round dance is performed until the resource is about 10 metres away from the hive, transitional dances are performed when the resource is at a distance of 20 to 30 metres away from the hive, and finally, when it is located at distances greater than 40 metres from the hive ...

Courtship
Courtship is the period wherein some couples get to know each other prior to a possible marriage. Courtship traditionally may begin after a betrothal and may conclude with the celebration of marriage. A courtship may be an informal and private matter between two people or may be a public affair, or a formal arrangement with family approval. Traditionally, in the case of a formal engagement, it is the role of a male to actively "court" or "woo" a female, thus encouraging her to understand him and her receptiveness to a marriage proposal. Duration The average duration of courtship varies considerably throughout the world. Furthermore, there is vast individual variation between couples. Courtship may be completely omitted, as in cases of some arranged marriages where the couple do not meet before the wedding. In the United Kingdom, a poll of 3,000 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which in his view is intentional, whereas natural selection is not. Genetic diversity, Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the Cell (biology), cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Communication
Plants can be exposed to many stress factors such as disease, temperature changes, herbivory, injury and more. Therefore, in order to respond or be ready for any kind of physiological state, they need to develop some sort of system for their survival in the moment and/or for the future. Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, other plants (of the same or other species), animals, insects, and fungi. Plants communicate through a host of volatile organic compounds (VOCs) that can be separated into four broad categories, each the product of distinct chemical pathways: fatty acid derivatives, phenylpropanoids/ benzenoids, amino acid derivatives, and terpenoids. Due to the physical/chemical constraints most VOCs are of low molecular mass (< 300 Da), are |
Monologue
In theatre, a monologue (from el, μονόλογος, from μόνος ''mónos'', "alone, solitary" and λόγος ''lógos'', "speech") is a speech presented by a single character, most often to express their thoughts aloud, though sometimes also to directly address another character or the audience. Monologues are common across the range of dramatic media (plays, films, etc.), as well as in non-dramatic media such as poetry. Monologues share much in common with several other literary devices including soliloquies, apostrophes, and asides. There are, however, distinctions between each of these devices. Similar literary devices Monologues are similar to poems, epiphanies, and others, in that, they involve one 'voice' speaking but there are differences between them. For example, a soliloquy involves a character relating their thoughts and feelings to themself and to the audience without addressing any of the other characters. A monologue is the thoughts of a person spoken out l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daydreaming
Daydreaming is the stream of consciousness that detaches from current, external tasks when attention drifts to a more personal and internal direction. This phenomenon is common in people's daily life shown by a large-scale study in which participants spend 47% of their waking time on average on daydreaming. There are various names of this phenomenon including mind wandering, fantasy, spontaneous thoughts, etc. Daydreaming is the term used by Jerome L. Singer whose research laid the foundation for nearly all the subsequent research today. The terminologies assigned by researchers today puts challenges on identifying the common features of daydreaming, and on building collective work among researchers. There are many types of daydreams, and there is no consistent definition among psychologists. However, the characteristic that is common to all forms of daydreaming meets the criteria for mild dissociation.Klinger, Eric (October 1987). ''Psychology Today''. Also, the impacts of diff ...
