This paper examines a group of white speakers in South Philadelphia who exhibit appropriation of African American Vernacular English /TH/-fronting. Speakers with the most antagonistic contact and most aggressive attitudes toward their African American neighbors show the highest rates of /TH/-fronting. This paper argues that appropriation of the African American Vernacular English (AAVE) ethnole...

Existing studies of IT within early childhood education and care settings are scant, and those that do exist traditionally utilise a Cartesian world-view where humans and IT are separate self-sufficient entities with properties. In this worldview, change is attributed to either the technological or the human entity, leading to limited, either techno-centric or human-centred accounts of IT imple...

This case study uses a sociocultural perspective and the concept of appropriation (Newman, Griffin and Cole, 1989; Rogoff, 1990) to describe how a student learned to work with linear functions. The analysis describes in detail the impact that interaction with a tutor had on a learner, how the learner appropriated goals, actions, perspectives, and meanings that are part of mathematical practices...

a r t i c l e i n f o Business relationships provide means for creating and appropriating superior value in the marketplace. To date, research pertains almost exclusively to the value after relationship creation and sharing among exchange partners. Consequently, the interaction between value creation and value appropriation remains relatively unknown in collaborative relationships. Drawing on e...

Traditionally, the HCI design is greatly influenced by active knowledge harnessed during requirement elicitations. However, as the world of ICT moves towards user-centric computing with a need for evolving features, designers face challenges from heterogeneous users with complex needs, accessing technology with myriads of communication mediums. In response, this paper explores peoples’ inherent...

Humanity faces numerous problems of common-pool resource appropriation. This class of multi-agent social dilemma includes the problems of ensuring sustainable use of fresh water, common fisheries, grazing pastures, and irrigation systems. Abstract models of common-pool resource appropriation based on non-cooperative game theory predict that self-interested agents will generally fail to find soc...

Many previous papers have lamented the fact that the findings of past GSS research have been inconsistent. This paper develops a new model for interpreting GSS effects on performance (a Fit-Appropriation Model), which argues that GSS performance is affected by two factors. The first is the fit between the task and the GSS structures selected for use (i.e., communication support and information ...

A standard rationale for intellectual property is that by awarding a monopoly to innovators the government increases the amount of social surplus appropriated from invention, thereby improving efficiency. Indeed, if an inventor can appropriate the full surplus from his invention the first best will be obtained. We observe that while full appropriation is sufficient for efficiency, it is not nec...

Two utilitarian defenses, traceable to Bentham and Mill, are commonly offered for patents. It is contended that patents induce innovation, and that patents induce disclosure of innovation. Patents on some or all of the human genome pose particular challenges for these defenses. In the first instance, patents on nucleotide sequences entail the perverse notion of human reproduction qua infringeme...
