Listening to Academic Lectures Flashcards

In an economics lecture, the professor says: 'The law of diminishing returns posits that, beyond a certain point, each additional unit of input yields progressively smaller increases in output.' What does 'posits' mean?

Answer: States or proposes as a fact or principle

'Posit' means to put forward or propose something as a fact or principle — it is a formal academic verb used for stating theoretical claims.

A professor says: 'While critics contend the theory is overly reductive, its proponents argue it provides a parsimonious explanation.' What does 'parsimonious' mean in this academic context?

Answer: Economical and using the fewest assumptions necessary to explain a phenomenon

In academic and scientific contexts, 'parsimony' refers to the principle of using the simplest explanation with the fewest assumptions — also known as Occam's Razor.

A professor discussing historiography says: 'We must be wary of anachronism when interpreting historical texts — judging past societies by the standards of our own time.' What does 'anachronism' mean?

Answer: The error of applying contemporary standards, concepts, or perspectives to a different historical period

'Anachronism' is the displacement of something out of its proper time period — particularly judging historical events by present standards that didn't exist then.

During a lecture on linguistics, a professor explains: 'Code-switching is the practice of alternating between two or more languages or language varieties within a single conversation.' A student then asks: 'Would that also include shifting between formal and informal registers?' What does the professor's topic relate to?

Answer: Language variation and how speakers adapt their language choices based on context and interlocutor

Code-switching and register-shifting are both aspects of language variation — how speakers adapt their language choices to context, audience, and purpose.

A professor says: 'The findings of this meta-analysis should be interpreted with caution, as the constituent studies employed heterogeneous methodologies.' What does 'heterogeneous' mean?

Answer: Diverse and varied, consisting of different types or kinds

'Heterogeneous' means consisting of diverse, different, or non-uniform elements — the opposite of 'homogeneous' (uniform and of the same kind).

A professor summarizing a lecture says: 'In sum, technological innovation and regulatory frameworks must evolve in tandem to effectively govern emerging AI systems.' What does 'in tandem' mean?

Answer: Together and simultaneously; in coordination with each other

'In tandem' means working together simultaneously and in coordination — the image comes from a tandem bicycle where two riders must pedal together.
