Tohunga Suppression Act 1907
The Tohunga Suppression Act 1907 was an Act of the New Zealand Parliament aimed at replacing tohunga as traditional Māori healers with western medicine. It was introduced by James Carroll who expressed impatience with what he considered regressive Māori attitudes, as he was worried those attitudes would isolate Māori. Officials had been concerned for years about the sometimes dangerous practices of tohunga. The Act was introduced in part to target Māori self-proclaimed prophet, faith healer and land rights activist Rua Kenana, but it was never used against him. It was praised by many influential Māori at the time, including Māui Pōmare and all four Māori MPs ( Āpirana Ngata, Hōne Heke Ngāpua, Tame Parata and Henare Kaihau). According to Willie Jackson, the prevailing concern raised by Ngata was the harm arising from improper medical practices, rather than the destruction of mātauranga Māori. The Act The Act contained only four clauses, the first of which si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suppression Of Communism Act
The Suppression of Communism Act, 1950 (Act No. 44 of 1950), renamed the Internal Security Act in 1976, was legislation of the national government in apartheid South Africa which formally banned the South African Communist Party, Communist Party of South Africa and proscribed any party or group subscribing to communism, according to a uniquely broad definition of the term. It was also used as the basis to place List of people subject to banning orders under apartheid, individuals under banning orders, and its practical effect was to isolate and silence voices of dissent. Description The Act, which came into effect on 17 July 1950, defined communism as any scheme aimed at achieving change—whether economic, social, political, or industrial—"by the promotion of disturbance or disorder" or any act encouraging "feelings of hostility between the European and the non-European races [...] calculated to further [disorder]". The Minister of Justice and Correctional Services, Minister ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suppression (eye)
Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes. The area of a person's visual field that is suppressed is called the suppression scotoma (with a scotoma meaning, more generally, an area of partial alteration in the visual field). Suppression can lead to amblyopia. Effect Nobel-prize winner David H. Hubel described suppression in simple terms as follows: :"Suppression is familiar to anyone who has trained himself to look through a monocular microscope, sight a gun, or do any other strictly one-eye task, with the other eye open. The scene simply disappears for the suppressed eye."David H. Hubel: ''Eye, Brain, and Vision'', Chapter 9 "Deprivation and development"section "Strabismus" Published online by Harvard Medical School (downloaded 30 Septembe ...

Fire Suppression System
Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring. Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different applications being used today. Of these, there are some that are still in use but are no longer legal to manufacture and produce, such as Halon 1301. Suppression systems Fire suppression systems are governed by the codes under the National Fire Protection Association, also known as the NFPA. This organization writes codes, regulations, and recommendations on the proper installation and maintenance of these fire suppression systems. Likewise, the NFPA also lists criteria that must be met for the requirements of certain types of fire suppression systems. Types * Fire sprinkler systems ** Wet pipes ***This is the most common sprinkler system. Once the bulb filled with water inside of the pipe heat ...

Voter Suppression
Voter suppression is the discouragement or prevention of specific groups of people from voting or registering to vote. It is distinguished from political campaigning in that campaigning attempts to change likely voting behavior by changing the opinions of potential voters through persuasion and organization, activating otherwise inactive voters, or registering new supporters. Voter suppression, instead, attempts to gain an advantage by reducing the Voter turnout, turnout of certain voters. Suppression is an anti-democratic tactic associated with authoritarianism. The tactics of voter suppression range from changes that increase voter fatigue, to Electoral fraud#Intimidation, intimidating or Political violence, harming prospective voters. Impact Some argue the term 'voter suppression' downplays the harm done when voices are not reflected in an election, calling for terms like 'vote destruction' that accounts for the permanence of each vote not being cast. Making it harder to vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thought Suppression
Thought suppression is a psychoanalytical defense mechanism. It is a type of motivated forgetting in which an individual consciously attempts to stop thinking about a particular thought. It is often associated with obsessive–compulsive disorder (OCD). OCD is when a person will repeatedly (usually unsuccessfully) attempt to prevent or "neutralize" intrusive distressing thoughts centered on one or more obsessions. It is also thought to be a cause of memory inhibition, as shown by research using the think/no think paradigm. Thought suppression is relevant to both mental and behavioral levels, possibly leading to effects which intensify the intrusive thought, which is contrary to the intention. Ironic process theory is one cognitive model that can explain the paradoxical effect. When an individual tries to suppress thoughts under a high cognitive load, the frequency of those thoughts increases and becomes more accessible than before.Wenzlaff, R.M., Bates, D.E. (October 2000). Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suppression Subtractive Hybridization
Subtractive hybridization is a technology that allows for PCR-based amplification of only cDNA fragments that differ between a control (driver) and experimental transcriptome. cDNA is produced from mRNA. Differences in relative abundance of transcripts are highlighted, as are genetic differences between species. The technique relies on the removal of dsDNA formed by hybridization between a control and test sample, thus eliminating cDNAs or gDNAs of similar abundance, and retaining differentially expressed, or variable in sequence, transcripts or genomic sequences. Suppression subtractive hybridization has also been successfully used to identify strain- or species-specific DNA sequences in a variety of bacteria including ''Vibrio'' species (Metagenomics Metagenomics is the study of all genetics, genetic material from all organisms in a particular environment, providing insights into their composition, diversity, and functional potential. Metagenomics has allowed researcher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transient-voltage-suppression Diode
A transient-voltage-suppression (TVS) diode, also transil, transorb or thyrector, is an electronic component used to protect electronics from voltage spikes induced on connected wires. Description The device operates by shunting excess current when the induced voltage exceeds the avalanche breakdown potential. It is a clamp (circuit), clamping device, suppressing all overvoltages above its breakdown voltage. It automatically resets when the overvoltage goes away, but absorbs much more of the transient energy internally than a similarly rated crowbar (circuit), crowbar device. A transient-voltage-suppression diode may be either unidirectional or bidirectional. A unidirectional device operates as a rectifier in the forward direction like any other avalanche diode, but is made and tested to handle very large peak currents. A bidirectional transient-voltage-suppression diode can be represented by two mutually opposing avalanche diodes in series with one another and connected in p ...

Suppression (parish)
In the Catholic Church, a parish () is a stable community of the faithful within a particular church, whose pastoral care has been entrusted to a parish priest (Latin: ''parochus''), under the authority of the diocesan bishop. It is the lowest ecclesiastical subdivision in the Catholic episcopal polity, and the primary constituent unit of a diocese or eparchy. Parishes are extant in both the Latin and Eastern Catholic Churches. In the 1983 Code of Canon Law, parishes are constituted under cc. 515–552, entitled "Parishes, Pastors, and Parochial Vicars." Types Most parishes are ''territorial parishes'', which comprise all the Christian faithful living within a defined geographic area. Some parishes may be joined with others in a deanery or ''vicariate forane'' and overseen by a ''vicar forane'', also known as a ''dean'' or ''archpriest''. Per canon 518, a bishop may also erect non-territorial parishes, or ''personal parishes'', within his see. Personal parishes are created to be ...

Suppression Order
A gag order (also known as a gagging order or suppression order) is an order, typically a legal order by a court or government, restricting information or comment from being made public or passed on to any unauthorized third party. The phrase may sometimes be used of a private order by an employer or other institution. Uses of gag orders include keeping trade secrets of a company, protecting the integrity of ongoing police or military operations, and protecting the privacy of victims or minors. Conversely, as their downside, they may be abused as a useful tool for those of financial means to intimidate witnesses and prevent release of information, using the legal system rather than other methods of intimidation. Strategic lawsuit against public participation Strategic lawsuits against public participation (also known as SLAPP suits or intimidation lawsuits), or strategic litigation against public participation, are lawsuits intended to censor, intimidate, and silence critics ...

Suppressive Fire
In military science, suppressive fire is "fire that degrades the performance of an enemy force below the level needed to fulfill its mission". When used to protect exposed friendly troops advancing on the battlefield, it is commonly called covering fire. Suppression is usually only effective for the duration of the fire. It is one of three types of fire support, which is defined by NATO as "the application of fire, coordinated with the maneuver of forces, to destroy, neutralise or suppress the enemy". Before NATO defined the term, the British and Commonwealth armies generally used "neutralisation" with the same definition as suppression. NATO now defines neutralisation as "fire delivered to render a target temporarily ineffective or unusable". Usage Suppressive fire usually achieves its effect by threatening casualties to individuals who expose themselves to it, forcing them to inactivity and ineffectiveness by keeping their heads down, 'or else take a bullet'.
