Using multi-modal bio-digital technologies to support the assessment of cognitive abilities of children with physical and neurological impairments

Gan, Hock Chye January 2015 (has links)
Current studies done using a learning test for children have problems as they only make evaluations of Physically and Neurologically Impaired (PNI) children who can succeed in the test and can be considered as a PASS/FAIL test. This pilot study takes a holistic view of cognitive testing of PNI children using a user-test-device triad model and provides a framework using non-PNI children and adults as controls. Comparisons using adapted off-the-shelf novel interfaces to the computer, in particular, an Electroencephalograph (EEG) head-set, an eye-tracker and a head-tracker and a common mouse were carried out. In addition, two novel multi-modal technologies were developed based on the use of brain-waves and eye-tracking as well as head-tracking technologies to support the study. The devices were used on three tests with increasing cognitive complexity. A self-developed measure based on success streaks (consecutive outcomes) was introduced to improve evaluations of PNI children. A theoretical model regarding a fit of ability to devices was initially setup and finally modified to fit the view of the empirical model that emerged from the outcomes of the study. Results suggest that while multi-modal technologies can address weaknesses of the individual component modes, a compromise is made between the user’s ability for multi-tasking between the modes and the benefits of a multi-modal device but the sample size is very small. Results also show children failing a test with a mouse but passing it subsequently when direct communication is used suggesting that a device can affect a test for children who are of a developing age. This study provides a framework for a more meaningful conversation between educational psychologists as well as other professionals and PNI parents because it provides more discrimination of outcomes in cognitive tests for PNI children. The framework provides a vehicle that addresses scientifically the concerns of parents and schools.

Vem har ansvar över de utsatta filippinska barnen? : En kvalitativ studie om svenska aktörers arbete kring live-streamade sexuella övergrepp på filippinska barn

Bergström, Cassandra, Helgodt, Tove January 2020 (has links)
Denna studie undersöker olika svenska aktörers arbete mot live-streamade sexuella övergrepp på filippinska barn samt deras syn på ansvarstagande gällande fall där svenska förövare begår detta brott. Det finns fyra svenska rättsfall där svenska män dömts för att ha beställt, regisserat och bevittnat sexuella övergrepp på barn i dagsläget. I dokumentärer och radioprogram som lyfter problematiken framkommer att dessa övergrepp sker i det dolda (på internet) och att det därmed finns ett stort mörkertal som innebär att övergreppen fortsätter att ske och att barnen riskerar att inte få rätt stöd och hjälp. Syftet med studien är därför att bidra med fördjupad kunskap inom området genom att undersöka huruvida svenska frivillighetsorganisationer samt myndigheter anser att deras arbete är tillräckligt eller behöver utvecklas. Det empiriska materialet bygger på fem intervjuer med ett urval av svenska myndigheter och frivilligorganisationer, där en aktör befinner sig på Filippinerna. Studien har en kvalitativ och induktiv ansats där resultatet analyseras utifrån Ludwig von Bertalanffys generella systemteori samt tidigare relevant forskning. Resultatet visar att informanterna anser att svenska aktörer har ett stort internationellt ansvar för de filippinska barn som blir utsatta för live-streamade övergrepp då förövarna är svenska. Två informanter menar att Sverige inte gör tillräckligt för dessa barn i nuläget. Samtidigt menar vissa informanter att ansvaret slutar någonstans och att Filippinernas egna aktörer behöver ta vid då vissa insatser inte anses kunna skötas från Sveriges håll. Resultatet visar även att nya idéer och resurser krävs för att de ska kunna uppfylla dessa ambitioner samt att det finns många utmaningar som försvårar och stoppar utvecklingen av arbetet. Empirin presenterar också möjligheter inom arbetet och förslag på nödvändiga åtgärder. I en avslutade diskussion lyfter vi fram bristen på ett barnfokus hos svenska aktörer samt några tankar kring vad detta kan bero på. Vi diskuterar även konsekvenserna av svenska rättsliga insatser för barnen och huruvida dessa gynnar eller skadar barnet. Avslutningsvis redovisar vi önskemål för framtida forskning inom området. / This study examines the work of various Swedish organizations regarding live-streamed sexual abuse of Filipino children and their view on responsibility for cases where Swedish perpetrators commit the crimes. There are four Swedish court cases where Swedish men have been convicted of this crime and documentaries and radio programs now highlight this problem. It appears that the crime is hidden, because it takes place on the internet, and for this reason there is a large number of hidden statistics that makes it difficult to protect and support the vulnerable children. The aim of this study is therefore to contribute with deeper knowledge in the area by examining whether Swedish non-governmental organizations and governmental authorities believe that their work is sufficient or needs to be developed. The empirical material is based on five interviews with a selection of Swedish authorities and non-governmental organizations. The study has a qualitative and inductive approach where the results are analyzed based on Ludwig von Bertalanffy's general systems theory and previous research. The result shows that the informants believe that Swedish actors have a great international responsibility for the Filipino children who are exposed to live-streamed abuse when the perpetrators are Swedish. Two informants believe that Sweden is not doing enough for these children at this moment. At the same time, some informants believe that their responsibility ends somewhere and that the Philippine government and non-governmental organizations have their responsibility. The result also shows that new ideas and resources are required for them to be able to fulfill these ambitions and that there are many challenges that stop the development of their work. The empiric also presents opportunities within the work and proposals for necessary measures for the future. Concluding in the discussion we highlight the lack of child focus among the work of Swedish governmental and nongovernmental organizations and what we believe is the reason for this. We also discuss the consequences of Swedish legal efforts for the children, such as damages, and whether these consequences benefit or harm the children. Finally, we come with suggestions for future research within the area.
