Developmental Niche
{{third-party, date=October 2020 The developmental niche is a theoretical framework for understanding and analyzing how culture shapes child development Child development involves the Human development (biology), biological, developmental psychology, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence. Childhood is divided into 3 stages o .... Developed by Charles M. Super and Sara Harkness. It is theoretically related to, and shares some origins with, Weisner’s “ecocultural niche,” and Worthman’sWorthman, C. M. (1994).

Ecological Niche
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another ndthe relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying behavioral adaptations. An Eltonian niche emphasizes that a spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niche Differentiation
In ecology, niche differentiation (also known as niche segregation, niche separation and niche partitioning) refers to the process by which competing species use the environment differently in a way that helps them to coexist. The competitive exclusion principle states that if two species with identical niches (ecological roles) compete, then one will inevitably drive the other to extinction. This rule also states that two species cannot occupy the same exact niche in a habitat and coexist together, at least in a stable manner. When two species differentiate their niches, they tend to compete less strongly, and are thus more likely to coexist. Species can differentiate their niches in many ways, such as by consuming different foods, or using different areas of the environment. As an example of niche partitioning, several anole lizards in the Caribbean islands share common diets—mainly insects. They avoid competition by occupying different physical locations.

Niche Market
A niche market is the subset of the market on which a specific product is focused. The market niche defines the product features aimed at satisfying specific market needs, as well as the price range, production quality and the demographics that it is intended to target. It is also a small market segment. Sometimes, a product or service can be entirely designed to satisfy a niche market. Not every product can be defined by its market niche. The niche market is highly specialized, and aiming to survive among the competition from numerous super companies. Even established companies create products for different niches; Hewlett-Packard has all-in-one machines for printing, scanning and faxing targeted for the home office niche, while at the same time having separate machines with one of these functions for big businesses. While you may have explicit moving items effectively at the top of the priority list. Although you can build your chances of achievement by beginning with a niche mar ...

Niche (protein Structural Motif)
In the area of protein structural motifs, niches are three or four amino acid residue features in which main-chain CO groups are bridged by positively charged or δ+ groups. The δ+ groups include groups with two hydrogen bond donor atoms such as NH2 groups and water molecules. In typical proteins, 7% of amino acid residues belong to niches bound to a δ+ group, while another 7% have the conformation but no single cationic bridging group is detected. Niches are of two kinds, distinguished as niche3 (3 residues, ''i'' to ''i+2'') and niche4 (4 residues, ''i'' to ''i+3''). In a niche3 motif the δ+-binding carbonyl groups are from residues ''i'' and ''i+2'' while in a niche4 motif they are from residues ''i'' and ''i+3''. A niche3 has the α conformation for residue ''i+1'' and the β conformation for residue ''i+2''; a niche4 has the α conformation for residues ''i+1'' and ''i+2'' and the β conformation for residue ''i+3''. A niche occurs commonly at the C-terminus of α-helices ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stem-cell Niche
Stem-cell niche refers to a microenvironment, within the specific anatomic location where stem cells are found, which interacts with stem cells to regulate cell fate. The word 'niche' can be in reference to the ''in vivo'' or ''in vitro'' stem-cell microenvironment. During embryonic development, various niche factors act on embryonic stem cells to alter gene expression, and induce their proliferation or differentiation for the development of the fetus. Within the human body, stem-cell niches maintain adult stem cells in a quiescent state, but after tissue injury, the surrounding micro-environment actively signals to stem cells to promote either self-renewal or differentiation to form new tissues. Several factors are important to regulate stem-cell characteristics within the niche: cell–cell interactions between stem cells, as well as interactions between stem cells and neighbouring differentiated cells, interactions between stem cells and adhesion molecules, extracellular matrix co ...

Bassline (music Genre)
Bassline (sometimes referred to as bassline house, organ house, Niche, B-Line, or 4x4) is a music genre related to UK garage that originated in Yorkshire and the Midlands in the early 2000s. Stylistically it comprises a four-to-the-floor rhythm normally at around 135–142 beats per minute and a strong emphasis on bass, similar to that of its precursor speed garage, with chopped up vocal samples and a pop music aesthetic. In the scene's early days the most prominent bassline club was Niche Nightclub in Sheffield, which became the centre of controversy due to a police raid which resulted in the club's closure in 2005. Characteristics Early bassline house Early bassline shares more similarities with its predecessor speed garage than the style that began to emerge in the latter half of the decade, with many people still referring to bassline house releases from the early 2000s as speed garage. This early style grew from the sound that was popular in nightclubs in Yorkshire and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niche (architecture)
A niche (CanE, or ) in Classical architecture is an exedra or an apse that has been reduced in size, retaining the half-dome heading usual for an apse. Nero's Domus Aurea (AD 64–69) was the first semi-private dwelling that possessed rooms that were given richly varied floor plans, shaped with niches and exedrae; sheathed in dazzling polished white marble, such curved surfaces concentrated or dispersed the daylight. A is a very shallow niche, usually too shallow to contain statues, and may resemble a blind window (a window without openings) or sealed door. (Compare: blind arcade) The word derives from the Latin (), via the French . The Italian '' nicchio'' () may also be involved,OED, "Niche" as the traditional decoration for the top of a niche is a scallop shell, as in the illustration, hence also the alternative term of "conch" for a semi-dome, usually reserved for larger exedra. In Gothic architecture, a niche may be set within a tabernacle framing, like a richly de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbarium
A columbarium (; pl. columbaria) is a structure for the reverential and usually public storage of funerary urns, holding cremated remains of the deceased. The term can also mean the nesting boxes of pigeons. The term comes from the Latin "'' columba''" (dove) and, originally, solely referred to compartmentalized housing for doves and pigeons called a dovecote. Background Roman columbaria were often built partly or completely underground. The Columbarium of Pomponius Hylas is an ancient Roman example, rich in frescoes, decorations, and precious mosaics. Today's columbaria can be either free standing units, or part of a mausoleum or another building. Some manufacturers produce columbaria that are built entirely off-site and brought to the cemetery by a large truck. Many modern crematoria have columbaria. Examples of these are the columbaria in Père Lachaise Cemetery in Paris and Golders Green Crematorium in London. In other cases, columbaria are built into church structures. On ...

Niche (horse)
Niche (foaled 1990) was a British Thoroughbred racehorse best known for winning the Group 3 classic trial the Nell Gwyn Stakes and coming 2nd in the 1,000 Guineas, before her career was cut short by a freak accident on the gallops. Bred by Highclere Stud, Niche was owned by Lord Carnarvon - the Queen's racing manager, owner of top class fillies Lemon Souffle and Lyric Fantasy, and grandson of George Edward Stanhope Molyneux Herbert, 5th Earl of Carnarvon who discovered the tomb of Tutenkhamun. Racing career Trained by Richard Hannon, Sr., and ridden in all her races bar one by the (then) 57-year-old Lester Piggott, Niche started her career with three wins in a row, including the Group 3 Norfolk Stakes. In her fourth race, the Cherry Hinton Stakes (one of the top 2yo filly races of the season) she met Sayyedati for the first time, finishing fourth carrying a penalty. These fillies would battle for honours throughout their two- and three-year-old careers. Before the end of her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niche (video Game)
''Niche: A Genetics Survival Game'' is an indie simulation video game developed and published by Stray Fawn Studio, and was released on Steam Early Access for Microsoft Windows, Mac OS, and Linux-based systems on September 15, 2016 after a successful Kickstarter crowd-funding campaign. Its main aim is to breed certain traits or genes into a group of canine or feline creatures to make the pack genetically perfect for its environment. Gameplay The game starts off with the player choosing story mode, a quick how-to tutorial or sandbox mode, where the player chooses their animals and terrain for their tribes and environment and a short cut-scene of a tribe of nichelings living on an island. A large bird takes a child niche and tries to fly off with him but he falls onto a random island. This starts off the game by playing as a nicheling named Adam and the tutorial level. Game play and turns are organized into "days" which gives each animal a few actions of play each day. Game Mecha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
