For example, ana... | Discourse Representation Theory |
c_el1c629ha4o7 | A discourse is represented in a discourse representation structure (DRS), a box with variables at the top and the sentences in the formal language below in the order of the original discourse. Sub-DRS can be used for different types of sentences. One of the major advantages of DRT is its ability to account for donkey s... | Discourse Representation Theory |
c_0iuvgu00invs | Under a Montagovian approach, the indefinite a donkey, which is assumed to be inherently an existential quantifier, ends up becoming a universal quantifier, an unwelcome result because the change in quantificational force cannot be accounted for in any principled way. DRT avoids this problem by assuming that indefinite... | Discourse Representation Theory |
c_x6txkrmbhwlq | On the other hand, genuine quantifiers (e.g., 'every professor') bear scope. An 'every-NP' triggers the introduction of a complex condition of the form K1 → K2, where K1 and K2 are sub-DRSs representing the restriction and the scope of the quantification respectively. Unlike true quantifiers, indefinite noun phrases ju... | Discourse Representation Theory |

c_55mywtxklni0 | Theoretical physicist David Bohm (1917-1992) supports this view head-on. Bohm believed that a complete description of the universe would have to go beyond a simple list of all its particles and their positions, there would also have to be a physical quantum field associated with the properties of those particles guidin... | Holistic view |
c_x0ydfaofu0we | Bohm's ontological holism concerning the nature of whole physical systems was literal. But Niels Bohr, on the other hand, held ontological holism from an epistemological angle, rather than a literal one. Bohr (1885-1962) saw an observational apparatus to be a part of a system under observation, besides the basic physic... | Holistic view |
c_7vljdtonkca6 | His theory agrees with Bohm that whole systems were not merely composed of their parts and it identifies properties such as position and momentum as those of whole systems beyond those of its components. But Bohr states that these holistic properties are only meaningful in experimental contexts when physical systems ar... | Holistic view |
c_s962mc3p255c | In one sense, it is remarkable that DLCO has retained such clinical utility.
