Tidskriftsartikel (refereegranskat)abstract
- Evidence suggests that amyloid-beta (A beta) protofibrils/oligomers are pathogenic agents in Alzheimer's disease (AD). Unfortunately, techniques enabling quantitative estimates of these species in patients or patient samples are still rather limited. Here we describe the in vitro and ex vivo characteristics of a new antibody-based radioactive ligand, [I-125]mAb158, which binds to A beta protofibrils with high affinity. [I-125]mAb158 was specifically taken up in brain of transgenic mice expressing amyloid-beta protein precursor (A beta PP) as shown ex vivo. This was in contrast to [I-125]mAb-Ly128 which does not bind to A beta. The uptake of intraperitoneally-administered [I-125]mAb158 into the brain was age- and time-dependent, and saturable in A beta PP transgenic mice with modest A beta deposition. Brain uptake was also found in young A beta PP transgenic mice that were devoid of A beta deposits, suggesting that [I-125]mAb158 targets soluble A beta protofibrils. The radioligand was diffusely located in the parenchyma, sometimes around senile plaques and only occasionally colocalized with cerebral amyloid angiopathy. A refined iodine-124-labeled version of mAb158 with much improved blood-brain barrier passage and a shorter plasma half-life might be useful for PET imaging of A beta protofibrils.

Supporting embodied exploration of physical concepts in mixed digital and physical interactive settings

Konferensbidrag (refereegranskat)abstract
- In this paper findings are presented from a study on how sensor equipped computer game technologies can be used to create tools for educational settings to learn about for example concepts in physics. In a workshop focusing on the concept of gravity, a group of children interacted with an environment consisting of both physical and digital interactive components. We discuss how the mixed digital and physical setting affects the children's coordination and collaboration and their strategies to solve the given assignment. Findings suggest that the embodied nature of the technology create new opportunities for collaboration and that the alignment of the physical and digital parts of the interactive setting is important in order to create a seamless experience that takes advantage of the properties of the respective media.

See you on the subway: exploring mobile social software
- 2009. - 12
-
Konferensbidrag (refereegranskat)abstract
- This project explores the social possibilities of mobile technology in transitional spaces such as public transport. Based on a cultural probes study of Stockholm subway commuters, we designed a location-based friend finder that displays only people in the same train as the user. We aim at reaching a critical mass of users and therefore decided to make the system compatible with as many phones as possible, thus it was designed as a simple web application. An initial informal study pointed out consequences of certain design decisions on the user experience and highlighted social tensions created by presence awareness.

WEST: A Web Browser for Small Terminals
- 1999. - 1
-
Konferensbidrag (refereegranskat)abstract
- We describe WEST, a WEb browser for Small Terminals, that aims to solve some of the problems associated with accessing web pages on hand-held devices. Through a novel combination of text reduction and focus+context visualization, users can access web pages from a very limited display environment, since the system will provide an overview of the contents of a web page even when it is too large to be displayed in its entirety. To make maximum use of the limited resources available on a typical hand-held terminal, much of the most demanding work is done by a proxy server, allowing the terminal to concentrate on the task of providing responsive user interaction. The system makes use of some interaction concepts reminiscent of those defined in the Wireless Application Protocol (WAP), making it possible to utilize the techniques described here for WAP-compliant devices and services that may become available in the near future.

Seeing ethnographically: teaching ethnography as part of CSCW
- 2007. - 1
-
Konferensbidrag (refereegranskat)abstract
- While ethnography is an established part of CSCW research, teaching and learning ethnography presents unique and distinct challenges. This paper discusses a study of fieldwork and analysis amongst a group of students learning ethnography as part of a CSCW & design course. Studying the students’ practices we explore fieldwork as a learning experience, both learning about fieldsites as well as learning the practices of ethnography. During their fieldwork and analysis the students used a wiki to collaborate, sharing their field and analytic notes. From this we draw lessons for how ethnography can be taught as a collaborative analytic process and discuss extensions to the wiki to better support its use for collaborating around fieldnotes. In closing we reflect upon the role of learning ethnography as a practical hands on – rather than theoretical – pursuit.
