Appropriating Information Technology Artefacts through Trial and Error: The Case of the Tablet.

The concept of appropriation is of paramount importance for the lasting use of an Information Technology (IT) artefact following its initial adoption, and therefore its success. However, quite often, users' original expectations are negatively disconfirmed, and instead of appropriating the IT artefact, they discontinue its use. In this study we examine the use of IT artefacts following negative disconfirmation and use Grounded Theory Method techniques to analyse 136 blogposts, collected between March 2011 - July 2017, to investigate how users appropriate or reject the tablet when technology falls short of users' expectations.

The supratrochlear foramen of the humerus and its relation to the medullary canal: a potential surgical application.

Background: The supratrochlear foramen of the humerus is located at the septum separating the coronoid from the olecranon fossa. Beyond its anthropologic interest, that trait seems to have clinical significance as well.

Material/methods: The supratrochlear foramen was studied in 240 macerated adult humeri.

Verbal fluency in institutionalized patients with schizophrenia: age-related performance decline.

Several studies have reported a relatively stable level of cognitive deficits among patients with schizophrenia regardless of age, while others have suggested continued deterioration with age. We compared the performance of 42 institutionalized patients with schizophrenia and 42 age- and education-matched healthy controls on a semantic and phonemic verbal fluency test. Each group was divided into young participants (<65 years old) and elderly participants (> or =65 years old).
