Transmission and diffusion
Transmission
Intragenerational
Not intragenerational (e.g. with L2 speakers) Operstein2015 - this one is probably closer to the definition of Labov's diffusion
Liverpool - Clark and Watson (2016)
Diffusion
Gravity vs wave + other models
Models of diffusion: at least 4 (Beiley et al 1993???)
attitude plays a role (prestige): Norway, US - Canada, Clark and Watson (2016)
relocation vs expansion diffusion + barriers and amplifiers
sounds vs lexical items:
different channels of communication and different models of diffusion (see
Fitzsimmons 2010
)
geographical and between social groups (Afro Americans, Latinos etc)
Models of change
Wave
Family-tree model
Kressing (2016) - on the history of family tree and wave model etc
Attempt to create a model taking into account both - operstein 2015
Relation btw transmission and diffusion
Labov: diffusion happens once, then the feature is transmitted
Cukor (2011): pattern can differ, as in the current study - features are diffused 2 times and then transmitted
