Where does aspect collide?

In linguistics, aspect is the grammatical category that expresses how a speaker views the internal temporal structure of an event: whether it is presented as complete and bounded or as ongoing, habitual, or unfolding, independently of when it happened. Comrie's 1976 Aspect set out the perfective and imperfective as the central distinction and kept aspect separate from tense, which locates an event in time rather than describing its shape. The referent is a feature of verb meaning and morphology, marked on the verb and studied across languages, not a facing slope, a concern pulled out of code, or a way of seeing a picture.[1]

Unit

A grammatical marking of an event's temporal shape, such as perfective or imperfective

Recovery means

Not applicable

Measured by

Identified through morphological marking, verb forms, and native-speaker judgements about whether an event is bounded or ongoing

In software engineering, an aspect is a concern that cuts across many parts of a program, such as logging, security, or error handling, gathered into a single module instead of being scattered and tangled through the code it touches. Kiczales and colleagues' 1997 Aspect-oriented programming named these cross-cutting concerns and proposed a way to express each one as an aspect that is woven into the base program at defined points. The referent is a unit of program modularity in a design method, defined by the concern it isolates, and it has nothing to do with a verb's temporal shape, the direction a hillside faces, or perceiving an image one way rather than another.[2]

Unit

A cross-cutting concern captured as one program module

Recovery means

Not applicable

Measured by

Assessed by the code scattering and tangling it removes and by where its behaviour is woven into the base program

In physical geography, the aspect of a slope is the compass direction it faces, which governs how much solar radiation it receives and so shapes its temperature, moisture, and vegetation: in the northern hemisphere a south-facing slope is warmer and drier than a north-facing one at the same place. Bennie and colleagues' 2008 Slope, aspect and climate modelled how slope and aspect together set the microclimate of chalk grassland through their effect on insolation. The referent is an orientation of terrain, measured in degrees of bearing, and it is unrelated to a verb's aspect, an aspect in a program, or a way of seeing.[3]

Unit

The bearing a slope faces, in degrees or compass direction

Recovery means

Not applicable

Measured by

Derived from a digital elevation model or read in the field as the downslope compass bearing, then linked to modelled insolation

In philosophy, an aspect is what one perceives when the same unchanging figure is suddenly seen as one thing rather than another, as in the duck-rabbit that flips between two readings though the drawing itself does not change: noticing an aspect is a perceptual and conceptual event, not the discovery of a new property in the object. Wittgenstein's 1953 Philosophical investigations discussed this aspect-seeing, or seeing-as, and asked what changes when an aspect dawns. The referent is a mode of perception and the experience of it, described through examples and argument, and it shares nothing with a grammatical aspect, a slope's facing, or a module in code.[4]

Unit

An experienced way of seeing a figure as one thing rather than another

Recovery means

Not applicable

Measured by

Explored through described cases such as ambiguous figures and reports of an aspect dawning, not by a numerical measure
