Seeking Information on Social Commerce: An Examination of the Impact of User- and Marketer-generated Content Through an Eye-tracking Study
2021
Following the growing popularity of social commerce sites, there is an increased interest in understanding how consumers decide what products to purchase based on the available information. Consumers nowadays are confronted with the task of assessing marketer-generated (MGC) as well as user-generated information (UGC) in a range of different forms to make informed purchase-related decisions. This study examines the information types and forms that influence consumers in their decision-making process on social commerce. Building on uses and gratifications and dual-process theories, we distinguish between marketer and user generated content, and differentiate formats into informational and no…
Evaluation of Deep Learning and Conventional Approaches for Image Recaptured Detection in Multimedia Forensics
2022
Image recaptured from a high-resolution LED screen or a good quality printer is difficult to distinguish from its original counterpart. The forensic community paid less attention to this type of forgery than to other image alterations such as splicing, copy-move, removal, or image retouching. It is significant to develop secure and automatic techniques to distinguish real and recaptured images without prior knowledge. Image manipulation traces can be hidden using recaptured images. For this reason, being able to detect recapture images becomes a hot research topic for a forensic analyst. The attacker can recapture the manipulated images to fool image forensic system. As far as we know, ther…
Network measures in animal social network analysis : Their strengths, limits, interpretations and uses
2020
International audience; We provide an overview of the most commonly used social network measures in animal research for static networks or time‐aggregated networks. For each of these measures, we provide clear explanations as to what they measure, we describe their respective variants, we underline the necessity to consider these variants according to the research question addressed, and we indicate considerations that have not been taken so far. We provide a guideline indicating how to use them depending on the data collection protocol, the social system studied and the research question addressed. Finally, we inform about the existent gaps and remaining challenges in the use of several va…
Perspectives and reflections on teaching linear algebra
2020
Abstract This paper presents ‘expert opinions’ on what should be taught in a first-year linear algebra course at university; the aim is to gain a generic picture and general guiding principles for such a course. Drawing on a Delphi method, 14 university professors—called ‘experts’ in this study—addressed the following questions: What should be on a first-year linear algebra undergraduate course for engineering and/or mathematics students? How could such courses be taught? What tools (if any) are essential to these two groups of students? The results of the investigation, these experts’ opinions, mainly concern what should be in a linear algebra course (e.g. problem-solving and applications)…
Design and Investigation of a Touch Gesture for Dividing in a Virtual Manipulative Model for Equation-solving
2020
AbstractPhysical models for equation solving typically lack feedback regarding their appropriate use. Such feedback is possible in virtual environments and could be implemented in hybrid models. Based on an epistemological analysis, this article presents a touch gesture as a way for users to signal they want to divide both sides of an equation and a design for feedback on the use of this so-called ‘division gesture’. The design is investigated by contrasting a case study, in which students used an app with the division gesture, with a preparatory study where students had to perform corresponding actions on physical manipulatives. This investigation revealed insight into feedback functions, …
Dynamics of undergraduate engineering students’ learning activities in mathematics in an online and in a blended environment
2020
Paper IV is not published yet. This thesis reports from a research study which investigates the role of technology rich environments in undergraduate engineering students’ processes of learning mathematics. The research is founded within a naturalistic research paradigm (Lincoln, 2007) and adopts a case study design (Yin, 2014). The two cases under consideration comprise a small group of undergraduate electronics engineering students, selected as participants, from an online and a blended learning environment (Borba et al., 2016). The first case study of online environment incorporates an online system, MyMathLab, for homework and assessment, and tutorial videos for the lectures in a calcul…
Opportunities and Challenges when Students Work with Vocationally Connected Mathematics Tasks
2021
Students in vocational education in Norway take a compulsory mathematics course in the first year of their programme. This course offers opportunities for engaging with mathematics which can be highly relevant to practice in many workplaces. Working with vocationally connected mathematics tasks, tasks designed to draw on students’ future working contexts, is one way of trying to connect to students’ possible future vocations. This study aims to understand how students interact with such tasks with a particular emphasis on the roles of norms, authenticity and students’ positioning between the practices of school, the workplace and everyday life. In this study, I observed students working wit…
Omvendt undervisning i matematikk : en studie av elevers oppfatning av undervisningsmetoden
2013
Masteroppgave i matematikkdidaktikk- Universitetet i Agder 2013 Many teachers want to try out different teaching methods to find the one that makes students learn best. In today's society we surround ourselves with technology most of the day and there are several teaching methods that make use of technological tools in different ways. The “flipped classroom” is one of these and this is a method that has become more and more popular around the world and now also in Norway. In short, this is a method where students get theoretical review outside the classroom by using instructional videos, while solving problems and other learning activities are carried out at school with the teacher present.…
Forskningsbasert lærerutdanning i matematikk : hva betyr forskningsbasert undervisning for GLU studentene i MA-149?
2013
Masteroppgave i matematikkdidaktikk- Universitetet i Agder 2013 It is enshrined in law and regulation that all higher education should be research-based and research-oriented. How a research-based approach should be reflected in the education is not defined clearly, so there is room for interpretation that gives the institutions a certain freedom. In this study I examine how a mathematics education courses at the University of Agder is research-corrected and the consequences of that for the students. To see the significance the students believe a research-based course has, I through the study attempt to answer the following research questions: - What does mathematics education research mean…
Climate mitigation and intensified forest management in Norway: To what extent are surface waters safeguarded?
2020
AbstractWhile the role of forestry in mitigating climate change is increasingly subject to political commitment, other areas, such as water protection, may be at risk. In this study, we ask whether surface waters are sufficiently safeguarded in relation to the 2015 launch of a series of measures to intensify forest management for mitigation of climate change in Norway. First, we assess how impacts on water are accounted for in existing regulations for sustainable forestry. Secondly, we provide an overview of the impacts of forestry on water quality relevant to three support schemes: afforestation on new areas, increased stocking density in existing forests, and forest fertilisation. Lastly,…
