Value-added Modeling
Value-added modeling (also known as value-added measurement, value-added analysis and value-added assessment) is a method of teacher evaluation that measures the teacher's contribution in a given year by comparing the current test scores of their students to the scores of those same students in previous school years, as well as to the scores of other students in the same grade. In this manner, value-added modeling seeks to isolate the contribution, or value added, that each teacher provides in a given year, which can be compared to the performance measures of other teachers. VAMs are considered to be fairer than simply comparing student achievement scores or gain scores without considering potentially confounding context variables like past performance or income. It is also possible to use this approach to estimate the value added by the school principal or the school as a whole. Critics say that the use of tests to evaluate individual teachers has not been scientifically validated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VAM (bicycling)
VAM is the abbreviation for the Italian term ''velocità ascensionale media'', translated in English to mean "average ascent speed" or "mean ascent velocity", but usually referred to as VAM. It is also referred to by the English backronym "Vertical Ascent in Meters". The term, which was coined by Italian physician and cycling coach Michele Ferrari, is the speed of elevation gain, usually stated in units of metres per hour. Background VAM is a parameter used in cycling as a measure of fitness and speed; it is useful for relatively objective comparisons of performances and estimating a rider's power output per kilogram of body mass, which is one of the most important qualities of a cyclist who competes in stage races and other mountainous events. Dr. Michele Ferrari also stated that VAM values exponentially rise up with every gradient increase. For example, a 1180 VAM of a 64 kg rider on a 5% gradient is equivalent to a VAM of 1400 m/h on a 10 % or a VAM of 1675 m/h on a 13% gradient. ...

Arbuscular Mycorrhiza
An arbuscular mycorrhiza (AM) (plural ''mycorrhizae'', a.k.a. ''endomycorrhiza'') is a type of mycorrhiza in which the symbiont fungus (''AM fungi'', or AMF) penetrates the cortical cells of the roots of a vascular plant forming arbuscules. (Not to be confused with ectomycorrhiza or ericoid mycorrhiza.) Arbuscular mycorrhizae are characterized by the formation of unique structures, arbuscules and vesicles, by Glomeromycota and Mucoromycota, sister clades of the more well-known and diverse dikaryan fungi (all three are together called "symbiomycota"). AM fungi help plants to capture nutrients such as phosphorus, sulfur, nitrogen and micronutrients from the soil. It is believed that the development of the arbuscular mycorrhizal symbiosis played a crucial role in the initial colonisation of land by plants and in the evolution of the vascular plants. It has been said that it is quicker to list the plants that do not form endomycorrhizae than those that do. This symbiosis is a ...

Vehículos Automotores Mexicanos
Vehículos Automotores Mexicanos, S.A. (VAM) was a Mexican automaker from 1946 to 1986. The original organization, a distributor and license manufacturer for Willys-Overland and AMC vehicles, became government controlled in 1963 with American Motors Corporation (AMC) holding a minority interest. The company imported and produced automobiles and light trucks under license from Willys, AMC, Eagle, Jeep, Chrysler, Renault and designed their own vehicles based on AMC platforms. The early-1980s collapse of the Mexican economy forced a sale of the Mexican government's interest in VAM to Renault, which shut down the firm in the late 1980s. The Mexican government maintains the rights to the VAM name and brand to this day. History ''Vehículos Automotores Mexicanos'' was established as its own company 1963 after the Mexican Government passed a law to control the privately owned ''Sociedad Mexicana de Credito Industrial'' (SOMEX), the parent company of Willys Mexicana S.A.

Victoria And Albert Museum
The Victoria and Albert Museum (often abbreviated as the V&A) in London is the world's largest museum of applied arts, decorative arts and design, housing a permanent collection of over 2.27 million objects. It was founded in 1852 and named after Queen Victoria and Prince Albert. The V&A is located in the Royal Borough of Kensington and Chelsea, in an area known as "Albertopolis" because of its association with Prince Albert, the Albert Memorial and the major cultural institutions with which he was associated. These include the Natural History Museum, the Science Museum, the Royal Albert Hall and Imperial College London. The museum is a non-departmental public body sponsored by the Department for Digital, Culture, Media and Sport. As with other national British museums, entrance is free.

Vinyl Acetate Monomer
Vinyl acetate is an organic compound with the formula CH3CO2CH=CH2. This colorless liquid is the precursor to polyvinyl acetate and ethene-vinyl acetate copolymers, important industrial polymers. Production The worldwide production capacity of vinyl acetate was estimated at 6,969,000 tonnes/year in 2007, with most capacity concentrated in the United States (1,585,000 all in Texas), China (1,261,000), Japan (725,000) and Taiwan (650,000). The average list price for 2008 was US$1600/tonne. Celanese is the largest producer (ca 25% of the worldwide capacity), while other significant producers include China Petrochemical Corporation (7%), Chang Chun Group (6%), and LyondellBasell (5%). It is a key ingredient in furniture glue. Preparation Vinyl acetate is the acetate ester of vinyl alcohol. Since vinyl alcohol is highly unstable (with respect to acetaldehyde), the preparation of vinyl acetate is more complex than the synthesis of other acetate esters. The major industrial rout ...

Violence Against Men
Violence against men is a term for violent acts that are disproportionately or exclusively committed against men or boys. Men are over-represented as both perpetrators and victims of violence. Perceptions and aspects Studies of social attitudes show violence is perceived as more or less serious depending on the gender of victim and perpetrator. Reporting on violence against men shows disparities; people are less likely to report a man hitting another man to the police than a man hitting a woman. Male law enforcement officers show a greater reluctance to file charges or reports when a man is the victim of domestic violence. The use of stereotypes by law enforcement is a recognised issue, and international law scholar Solange Mouthaan argues that, in conflict scenarios, sexual violence against men has been ignored in favor of a focus on sexual violence against women and children. One explanation for this difference in focus is the physical power that men hold over women, making ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Aryan Resistance (Sweden)
White Aryan Resistance ( sv, Vitt Ariskt Motstånd, VAM) was a militant neo-nazi network active in Sweden between 1991 and 1993. The name of the group was derived from the US white supremacist organisation White Aryan Resistance (WAR). According to Stieg Larsson, a researcher of white supremacist organizations, the group was rather styled on the then already defunct US white supremacist group The Order, led by Robert Matthews. VAM was founded by Klas Lund, other leading members were Torulf Magnusson and Peter Melander, editor of the group's magazine ''Storm''. The organisation's symbol was the "Wolfsangel". VAM has been implicated in many serious crimes in Sweden, including the infamous Malexander police-murders, car bombings of political journalists and murders of perceived opponents. According to a report prepared and jointly published in November 1999 by Sweden's four largest daily newspapers, '' Aftonbladet'', '' Expressen'', ''Dagens Nyheter'' and '' Svenska Dagbladet ...

Villa International Airport Maamigili
Villa International Airport Maamigili , also known as Villa-Maamigili Airport, is an airport in the Maldives. It is located on the island of Maamigili in Alif Dhaal Atoll. The airport was developed by Maldivian business tycoon Qasim Ibrahim, who grew up in Maamigili, as a project to develop the infrastructure and facilities of the island. He has started a project to build new runways so planes from abroad visiting his resorts will be able to land directly on this airport, instead of having to stop off at Malé airport. It was developed and operated by his company, Villa Group, on land leased from the government. The airport opened up direct transportation facilities to two of their flagship resorts located on adjacent islands. The opening of the airport coincided with Villa's entry into the aviation industry, the founding of a new airline Villa Air (operating as ''Flyme''), to operate from the airport. The airport opened on October 1, 2011 as a domestic airport. In 2013, it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Antenna Mapping
Virtual Antenna Mapping (VAM) is used in wireless telecom networks. Typically when MIMO is deployed using two power Amplifier for two transmit antennae, there is a risk that both power amplifiers are not optimally used. Non-MIMO traffic would be using up to half of the available power whereas MIMO traffic could use the full power. This could potentially have an adverse impact on the overall cell throughput. VAM is used to achieve the goal of power balancing the physical channels across the multiple physical antennas especially when MIMO is deployed in the downlink. VAM gives an illusion to the UE that there are actually fewer antennas at the base station than it actually has. The unbalanced balanced power across two transmits paths are transformed into balanced power at physical antenna ports by VAM. This is achieved using phase and amplitude coefficients (V11, V12, V21, V22) as depicted in the figure. Thus both the power amplifiers are optimally used even for signals transmitte ...
