Passive Voice
A passive voice construction is a grammatical voice construction that is found in many languages. In a clause with passive voice, the grammatical subject expresses the ''theme'' or ''patient'' of the main verb – that is, the person or thing that undergoes the action or has its state changed. This contrasts with active voice, in which the subject has the agent role. For example, in the passive sentence "The tree was pulled down", the subject (''the tree'') denotes the patient rather than the agent of the action. In contrast, the sentences "Someone pulled down the tree" and "The tree is down" are active sentences. Typically, in passive clauses, what is usually expressed by the object (or sometimes another argument) of the verb is now expressed by the subject, while what is usually expressed by the subject is either omitted or is indicated by some adjunct of the clause. Thus, turning an active sense of a verb into a passive sense is a valence-decreasing process ("detransiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Passive Language
A passive speaker (also referred to as a receptive bilingual or passive bilingual) is a category of speaker who has had enough exposure to a language in childhood to have a native-like comprehension of it, but has little or no active command of it. Passive fluency is often brought about by being raised in one language (which becomes the person's passive language) and being schooled in another language (which becomes the person's native language). Such speakers are especially common in language shift communities where speakers of a declining language do not acquire active competence. For example, around 10% of the Ainu people who speak the language are considered passive speakers. Passive speakers are often targeted in language revival efforts to increase the number of speakers of a language quickly, as they are likely to gain active and near-native speaking skills more quickly than those with no knowledge of the language. They are also found in areas where people grow up hearin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passivity (behavior)
Deference (also called submission or passivity) is the condition of submitting to the espoused, legitimate influence of one's superior or superiors. Deference implies a yielding or submitting to the judgment of a recognized superior, out of respect or reverence. Deference has been studied extensively by political scientists, sociologists, and psychologists. Politics Smolenski (2005) examines deference in colonial Pennsylvania, to see how claims to political authority were made, justified, and accepted or rejected. He focuses on the "colonial speech economy," that is, the implicit rules that determined who was allowed to address whom and under what conditions, and describes how the qualities that inspired deference changed in the province from 1691 to 1764. The Quaker elite initially established a monopoly on political leadership based on what they believed to be their inherent civic virtue grounded in their religious and social class. By 1760, this view had been discredited and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive-aggressive Behavior
Passive-aggressive behavior is characterized by a pattern of passive hostility and an avoidance of direct communication. Inaction where some action is socially customary is a typical passive-aggressive strategy (showing up late for functions, staying silent when a response is expected). It is typically used to avoid confrontation, rejection, or criticism. Passive-aggressive behavior is sometimes protested by associates, evoking exasperation or confusion. People who are recipients of passive-aggressive behavior may experience anxiety due to the discordance between what they perceive and what the perpetrator is saying. Application Psychology In psychology, "passive-aggression" is one of the most misused psychological terms. After some debate, the American Psychiatric Association dropped it from the list of personality disorders in the DSM IV as too narrow to be a full-blown diagnosis and not well enough supported by scientific evidence to meet increasingly rigorous standards of d ...

Passive Income
Passive income is a type of unearned income that is acquired with little to no labor to earn or maintain. It is often combined with another source of income, such as regular employment or a side job. Passive income, as an acquired income, is typically taxable. Examples of passive income include rental income and business activities in which the earner does not materially participate. Some jurisdictions' taxing authorities, such as the Internal Revenue Service in the United States, distinguish passive income from other forms of income, such as income from regular or contractual employment, and may tax it differently. It can take a long period of work and accumulation before passive income can be acquired. Passive income can be a way of creating financial independence and early retirement, because the beneficiary will receive an income regardless of whether they are materially active in the activity creating the revenue. Passive income can come in the form of a lump sum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Immunity
In immunology, passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non- immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or antiserum therapy. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases. Passive immunization can be provided when people cannot synthesize antibodies, and when they have been exposed to a disease that they do not have immunity against. Naturally acquired Maternal passive immunity Maternal passive immunity is a type of naturally acquired passiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passivation (chemistry)
In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation in the air. As a technique, passivation is the use of a light coat of a protective material, such as metal oxide, to create a shield against corrosion. Passivation of silicon is used during fabrication of microelectronic devices. Undesired passivation of electrodes, called "fouling", increases the circuit resistance so it interferes with some electrochemical applications such as electrocoagulation for wastewater treatment, amperometric chemical sensing, and electrochemical synthesis. When exposed to air, many metals naturally form a hard, relatively inert surface layer, usually an oxide (termed the "native oxid ...

Passivity (engineering)
Passivity is a property of engineering systems, most commonly encountered in analog electronics and control systems. Typically, analog designers use ''passivity'' to refer to incrementally passive components and systems, which are incapable of Gain (electronics), power gain. In contrast, control systems engineers will use ''passivity'' to refer to thermodynamically passive ones, which consume, but do not produce, energy. As such, without context or a qualifier, the term ''passive'' is ambiguous. An electronic circuit consisting entirely of passive components is called a passive circuit, and has the same properties as a passive component. If a device is ''not'' passive, then it is an active device. Thermodynamic passivity In control systems and circuit network theory, a passive component or circuit is one that consumes energy, but does not produce energy. Under this methodology, voltage source, voltage and current sources are considered active, while resistors, capacitors, ind ...

Passive Solar Building Design
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis. Elements to be considered include window placement and size, and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be adapted or "retrofitted". Passive energy gain ''Passive solar'' technologies use sunlight without active mechanical systems (as contrasted to ''active solar'', which uses thermal collectors). Such technologies convert sunlight into usable heat (in water, air, and thermal mass), cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
