Agriculture is the science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products.

Agriculture

"It has mainly been the large landowners in Gondosari who have been in a position to take advantage of the modernisasi of agricultural production. Long before the seventies they enjoyed a dominant economic, social and political position in the village. Closely linked by family ties,7 they have occupied all the important positions (such as village head and members of the village administration) since the end of the last century. In this way they have been able to maintain and enlarge their economic power."[1]

"After 1971 the number of participants increased, but rich farmers and large landowners remained the dominant group."[1]

Dominant group

The two-word term dominant group is the topic of its original research proposal. Each of the hypotheses so far conjectured may have some resolution in agriculture.

Soils

"Although either dendrogram shows that the same three dominant groups are present in this soil (the Proteobacteria, the Cytophaga-Flexibacter-Bacteroides group, and the low-G+C gram-positive group), the proportion of clones that were unrelated to known major taxa within the domain Bacteria was higher with the conserved region than with the hypervariable region."[2]

"Since we were interested only in determining the dominant groups of soil microorganisms, a partial [rDNA] sequence analysis was justified. [...] since none of the 124 sequences we analyzed were similar to those of the Archaea, Archaea are probably not a dominant group in this soil. [...] With respect to specific genera, dominant microorganisms found in soil by culture methods were of the genera Arthrobacter (5 to 60%), Bacillus (7 to 67%), Pseudomonas (3 to 15%), Agrobacterium (1 to 20%), Alcaligenes (1 to 20%), and Flavobacterium (1 to 20%) and the order Actinomycetales (5 to 20%) (3). Of these groups, only Bacillus (19%) and Actinomycetales (0.8%) were found in our analysis."[2]

"Based on the results from pure cuIture incubations of methanotrophs and ammonium oxidizers, 14CH4/14CO ratios of >0.05 suggest that CH4 oxidizers were the dominant group while ratios of <0.05 suggest that NH4 oxidizers were the primary group (Jones et al. 1984)."[3]

Ants

"Agriculture is a specialized form of symbiosis that is known to have evolved in only four animal groups: humans, bark beetles, termites, and ants."[4]

"Attine ant agriculture is the product of an ancient, quadripartite, symbiotic relationship between three mutualists and one parasite. The mutualists include the attine ants, their fungal cultivars (Leucocoprineae and Pterulaceae), and filamentous bacteria in the genus Pseudonocardia (Actinomycetes) that grow on the integuments of the ants. The parasite, a fungus in the genus Escovopsis (Ascomycetes) known only from attine fungus gardens, infects those gardens as a “crop disease” and is controlled, at least in part, by an antibiotic produced by the Pseudonocardia bacterial symbiont (4, 10, 11)."[4]

"Such a recent origin for this ecologically dominant group explains their conspicuous absence from Dominican amber (15–20 mya) and may help to explain why, so far as is known, most leaf-cutting ants cultivate the same cultivar species (12–14)."[4]

Communication

"Newspaper coverage in some community newspapers frames the story in more complex and diverse ways and includes a wider range of voices than has been reported in studies of coverage in the national, elite press."[5]

"In this manner, news organizations act as a sentry, not for the community as a whole but for the dominant group(s) of power and influence. ... Terms that loaded highly on this factor included agriculture and agricultural."[5]

Agricultural policy

"The NFU [National Farmers Union] was challenged by the Central Landowners' Association (later the Country Landowners' Association) and the Central Chamber of Agriculture. More importantly, farmers were not the dominant group in agricultural policy-making."[6]

Farm women

"Those who try to break into the power structures may be ostracized not only by members of the dominant group but also by their peers (in this case other farm women)."[7]

Research

Hypothesis:

  1. One way technology enhances hominins is by feeding them adequately.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[8] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[9]"[10]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[11] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[12]

Proof of technology

"[T]he objective of a proof of technology is to determine the solution to some technical problem, such as how two systems might be integrated or that a certain throughput can be achieved with a given configuration."[13]

Def.

  1. "[a]n original object or form which is a basis for other objects, forms, or for its models and generalizations",[14]
  2. "[a]n early sample or model built to test a concept or process",[14] or
  3. "[a]n instance of a category or a concept that combines its most representative attributes"[14] is called a prototype.

Def. "[t]o test something using the conditions that it was designed to operate under, especially out in the real world instead of in a laboratory or workshop"[15] is called "field-test", or a field test.

A "proof-of-technology prototype ... typically implements one critical scenario to exercise or stress the highest-priority requirements."[16]

"[A] proof-of-technology test demonstrates the system can be used"[17].

"The strongest proof of technology performance is based on consistency among multiple lines of evidence, all pointing to similar levels of risk reduction."[18]
