- This work-in progress research paper addresses how the discussion forums in online courses are made useful to promote students' learning. This qualitative study investigates the interactions between learners, as well as between learners and teachers in MOOCs. Community of Inquiry was used as an analytical framework to unveil how the discussions made in the online environment may connect to the course participants' learning processes. Preliminary findings indicate that the interactions taking place in the discussion forums primarily concerns issues regarding course structure. Very few posts concern challenging reasoning or, conversations that may support learners to deepen their understanding of the subject matter at hand.

- The potential of technology enhanced learning (TEL) can have both pedagogical and administrative benefits. In a previous study, we investigated the drivers and barriers for TEL in higher education using Force Field Analysis (FFA). In this follow-up study, we collected new data through a questionnaire to a group of pedagogical developers and at a presentation at a university internal conference for teachers. A Kruskal Wallis test was carried out to test if the groups filling out questionnaire deviated from each other in their ranking. A comparison was also done to the scores in the previous study. As a result of this triangulation, deviations were found between ratings for seven of the 20 identified forces. While the assessments of strengths in FFA is debated, we argue that each group’s view is an important component to understand the situation, and triangulation of data is helpful in understanding the different views.

Therapeutic efficacy of dimethyl fumarate in relapsing-remitting multiple sclerosis associates with ROS pathway in monocytes
- 2019
-
Ingår i: Nature Communications. - : Nature Publishing Group. - 2041-1723. ; 10:1, s. 1-13

Tidskriftsartikel (refereegranskat)abstract
- Dimethyl fumarate (DMF) is a first-line-treatment for relapsing-remitting multiple sclerosis (RRMS). The redox master regulator Nrf2, essential for redox balance, is a target of DMF, but its precise therapeutic mechanisms of action remain elusive. Here we show impact of DMF on circulating monocytes and T cells in a prospective longitudinal RRMS patient cohort. DMF increases the level of oxidized isoprostanes in peripheral blood. Other observed changes, including methylome and transcriptome profiles, occur in monocytes prior to T cells. Importantly, monocyte counts and monocytic ROS increase following DMF and distinguish patients with beneficial treatment-response from non-responders. A single nucleotide polymorphism in the ROS-generating NOX3 gene is associated with beneficial DMF treatment-response. Our data implicate monocyte-derived oxidative processes in autoimmune diseases and their treatment, and identify NOX3 genetic variant, monocyte counts and redox state as parameters potentially useful to inform clinical decisions on DMF therapy of RRMS.

- Here we present our recent work on a droplet-based microfluidic device for manipulating microliter-sized droplets. By replacing the formerly used common dielectric SiO2 with Si3N4 and applying a 33 nm thick Teflon top layer to create a hydrophobic surface, we successfully lowered the actuation voltage from 450 V to 50 Vdc/40 Vac. Sputtered HfO2 with high dielectric constant was also investigated as an insulator, which could reproducibly yield thin defect-free insulation layers and lower the actuation voltage to less than 40 V.

Learning Object Annotation for Agricultural Learning Repositories
- 2009
-
Ingår i: ICALT. - New York, USA : IEEE. ; , s. 438-442
-
Konferensbidrag (refereegranskat)abstract
- This paper introduces a Web-based tool that has been developed to facilitate learning object annotation in agricultural learning repositories with IEEE LOM-compliant metadata. More specifically, it presents how an application profile of the IEEE LOM standard has been developed for the description of learning objects on organic agriculture and agroecology. Then, it describes the design and prototype development of the Organic.Edunet repository tool: a Web-based for annotating learning objects on organic agriculture and agroecology, organizing them in using a portfolio-like user interface in a learning repository, and then federating this repository with a network of agricultural learning repositories.

Adaptable metadata creation for the Web of Data
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- One approach to manage collections is to create data about the things in it. This descriptive data is called metadata, and this term is in this thesis used as a collective noun, i.e no plural form exists. A library is a typical example of an organization that uses metadata, to manage a collection of books. The metadata about a book describes certain attributes of it, for example who the author is. Metadata also provides possibilities for a person to judge if a book is interesting without having to deal with the book itself. The metadata of the things in a collection is a representation of the collection that is easier to deal with than the collection itself. Nowadays metadata is often managed in computer-based systems that enable search possibilities and sorting of search results according to different principles. Metadata can be created both by computers and humans. This thesis will deal with certain aspects of the human activity of creating metadata and includes an explorative study of this activity. The increased amount of public information that is produced is also required to be easily accessible and therefore the situation when metadata is a part of the Semantic Web has been considered an important part of this thesis. This situation is also referred to as the Web of Data or Linked Data.With the Web of Data, metadata records living in isolation from each other can now be linked together over the web. This will probably change what kind of metadata that is being created, but also how it is being created. This thesis describes the construction and use of a framework called Annotation Profiles, a set of artifacts developed to enable an adaptable metadata creation environment with respect to what metadata that can be created. The main artifact is the Annotation Profile Model (APM), a model that holds enough information for a software application to generate a customized metadata editor from it. An instance of this model is called an annotation profile, that can be seen as a configuration for metadata editors. Changes to what metadata can be edited in a metadata editor can be done without modifying the code of the application. Two code libraries that implement the APM have been developed and have been evaluated both internally within the research group where they were developed, but also externally via interviews with software developers that have used one of the code-libraries. Another artifact presented is a protocol for how RDF metadata can be remotely updated when metadata is edited through a metadata editor. It is also described how the APM opens up possibilities for end user development and this is one of the avenues of pursuit in future research related to the APM.

An RDF Modification Protocol, based on the needs of editing tools

Konferensbidrag (refereegranskat)abstract
- The use of RDF on the web is increasing, unfortunately the amount of editing tools suitable for end users without knowledge of technicalities of the language are not so common. We believe that a vital ingredient for the editing tools to flourish is a working remote modification protocol. This will allow editing tools to be developed separately from triple-stores and make them more flexible and reusable. Several initiatives for remote modification exist already but have not gained wide-spread adoption. In this paper we will show that most of them fall short when it comes to edit arbitrary RDF constructs, especially in combination with typical requirements of editing tools. We will first list these requirements, then propose a solution that fulfills them and finally outline an implementation. With this implementation we will also demonstrate how Annotation Profiles, a configuration mechanism for RDF metadata editors, has the additional feature of making modification requests very precise.

Digital meetings guided by the Community of Inquiry Framework
- 2024
-
Ingår i: The Design of Digital Learning Environments. - New York : Routledge. ; , s. 256-273
-
Bokkapitel (refereegranskat)abstract
- Digital meetings enable opportunity to conduct synchronous engagement in blended and online courses. Such meetings also provide favorable conditions for interaction and collaboration between students and teachers. Unfortunately, digital meetings often tend to be used for one-way communication, like traditional lectures. This chapter outlines the general advantages and limitations of digital meetings as an overview of the differences between synchronous digital and in-person meetings. Principles and guidelines addressing these limitations are presented based on the goal of creating and sustaining a community of inquiry during digital meetings. A study of how teachers perceive and plan for digital meetings in higher education is also presented and discussed from the perspective of Social and Teaching Presence. The chapter also includes a digital meeting template for practitioners to use when preparing and conducting digital meetings.
