Purpose: Individuals with tetraplegia depend on alternative interfaces in order to control computers and other electronic equipment. Current interfaces are often limited in the number of available control commands, and may compromise the social identity of an individual due to their undesirable appearance. The purpose of this study was to implement an alternative computer interface, which was fully embedded into the oral cavity and which provided multiple control commands.

 

Methods: The development of a wireless, intraoral, inductive tongue computer was described. The interface encompassed a 10-key keypad area and a mouse pad area. This system was embedded wirelessly into the oral cavity of the user. The functionality of the system was demonstrated in two tetraplegic individuals and two able-bodied individuals

 

Results: The system was invisible during use and allowed the user to type on a computer using either the keypad area or the mouse pad. The maximal typing rate was 1.8 s for repetitively typing a correct character with the keypad area and 1.4 s for repetitively typing a correct character with the mouse pad area.

 

Conclusion: The results suggest that this inductive tongue computer interface provides an esthetically acceptable and functionally efficient environmental control for a severely disabled user.

Including alternative stories in the mainstream. How transcultural young people in Norway perform creative cultural resistance in and outside of school

The development of an inclusive pedagogy takes on new urgency in Norwegian schools as the student body has become increasingly culturally and linguistically diverse. Traditionally, the Norwegian school has been dominated by homogenising and assimilating discourses, whereas alternative voices have been situated at the margins. In response to this tendency, we present two transcultural students’ autoethnographic stories produced in alternative spaces to the Norwegian mainstream, that is, in a transition class for newly arrived students and on Facebook. Both spaces are perceived as contact zones in the sense that they are culturally and linguistically complex. This article illustrates how the students perform cultural and linguistic resistance towards dominant homogenising discourses as the transition class and Facebook seem to offer opportunities for constructing alternative stories. Moreover, we contend that these alternative stories offer important knowledge for conventional education contexts since they represent stories of competence in contrast to the assumed limitations of these students.

Purpose 

The purpose of this study is to improve web-based employability interventions for employees with work-related health problems for both intervention content and study design by means of a pilot economic evaluation. 

 

Methods 

Uptake rate analysis for the intervention elements, cost effectiveness, cost utility and subgroup analyses were conducted to identify potential content-related intervention improvements. Differences in work ability and quality-adjusted life years and overall contribution of resource items to the total costs were assessed. These were used to guide study design improvements. 

 

Results 

Sixty-three participants were a-select allocated to either the intervention (n = 29) or the control (n = 34) group. Uptake regarding the intervention elements ranged between 3% and 70%. Cost-effectiveness and cost-utility analyses resulted in negative effects although higher total costs. Incremental effects were marginal (work ability −0.51; QALY −0.01).

 

Conclusions 

The web-based tool to enhance employability among work disabled employees requires improvements regarding targeting and intensity; outcome measures selected and collection of cost data. With respect to the studies of disability and rehabilitation, the findings and methods presented in this pilot economic evaluation could guide the assessment of future assistive “e-health” technologies.
