Nåden och gåvan i Philipp Melanchthons rättfärdiggörelselära 1521-1535

In this thesis Philip Melanchthon’s doctrine of justification is analyzed, especially the aspects of favor and donum in his writings until 1535. The research task is defined in the introduction of the thesis. Researchers agree, that Melanchthon emphasized the forensic aspect of the doctrine of justification, but this is not the case with the effective aspect of his doctrine of justification. Therefore, I have chosen to focus on the concepts of favor (grace) and donum (gift). The thesis begins with an analysis of the first edition of the Loci communes of 1521 in chapter two, and it ends with the second edition from 1535 in chapter seven. Melanchthon’s most important writings from the intervening period are analyzed in chapters three to six. In chapter eight, I describe my final results from the analysis. Although I have focused on how Melanchthon perceived the relationship between favor and donum, I have also taken note of such loci that are associated with his view of justification. I have done this in order to get a clearer picture of Melanchthon’s doctrine of justification, and of the issues which change in his theological thinking over time. In the research overview in chapter one, I divided the researchers in four different groups depending on how they perceive Melanchthon’s doctrine of justification. This classification is of course not comprehensive, since the reality is much more complicated. The main interpretations present in Melanchthon research are: 1. Christ as favor in justification, but donum is excluded from justification. 2. Christ as favor in justification, but the Spirit is donum in justification. 3. Christ as both favor and donum in justification until the early 1530s. 4. Christ as both favor and donum in justification throughout his life. The fourth option is in my opinion the most preferable. The analysis of Melanchthon’s writings shows that he expects both a forensic, and an effective aspect in the doctrine of justification throughout the examined period. Melanchthon strongly emphasizes that justification is by grace alone through faith for Christ’s sake, but also that the Holy Spirit works the justifying faith, and is the gift bestowed on believers in connection with this. Where the opponents according to Melanchthon see deeds, virtues, or a quality in the believer as the cause of the justification, there Melanchthon sees only Christ.

Novel Interaction Techniques for Mobile Augmented Reality applications. A Systematic Literature Review

This study reviews the research on interaction techniques and methods that could be applied in mobile augmented reality scenarios. The review is focused on themost recent advances and considers especially the use of head-mounted displays. Inthe review process, we have followed a systematic approach, which makes the reviewtransparent, repeatable, and less prone to human errors than if it was conducted in amore traditional manner. The main research subjects covered in the review are headorientation and gaze-tracking, gestures and body part-tracking, and multimodality– as far as the subjects are related to human-computer interaction. Besides these,also a number of other areas of interest will be discussed.

Depth sensors in augmented reality solutions. Literature review

The emergence of depth sensors has made it possible to track – not only monocular cues – but also the actual depth values of the environment. This is especially useful in augmented reality solutions, where the position and orientation (pose) of the observer need to be accurately determined. This allows virtual objects to be installed to the view of the user through, for example, a screen of a tablet or augmented reality glasses (e.g. Google glass, etc.). Although the early 3D sensors have been physically quite large, the size of these sensors is decreasing, and possibly – eventually – a 3D sensor could be embedded – for example – to augmented reality glasses. The wider subject area considered in this review is 3D SLAM methods, which take advantage of the 3D information available by modern RGB-D sensors, such as Microsoft Kinect. Thus the review for SLAM (Simultaneous Localization and Mapping) and 3D tracking in augmented reality is a timely subject. We also try to find out the limitations and possibilities of different tracking methods, and how they should be improved, in order to allow efficient integration of the methods to the augmented reality solutions of the future.

A service perspective to digital innovation: exploring the emergence of autonomous shipping

Current research describes digital innovation largely similar to product innovation. Digital innovation is seen as an object of coherent activities, however in reality digital innovation results from convergence of variant technologies and those related actors with versatile business goals. To account for the dynamic nature of digital innovation, this study applies a service perspective to digital innovation. The purpose of the study is to understand how digital innovation emerges within a service ecosystem for autonomous shipping. The sub-objectives of this study are to 1) identify what factors motivate and demotivate actors to integrate resources for autonomous shipping, 2) explore the key technology areas to be integrated to realise the autonomous shipping concept, and 3) suggest how the technology areas are combined for mutual value creation within a service eco-system for autonomous shipping. Insights from autonomous driving were also included. This study draws on literatures on service innovation and service-dominant logic. The research was conducted as a qualitative exploratory case study. The data comprise interviews of 18 marine and automotive industry experts, 4 workshops, 4 seminars, and observations as well as various secondary data sources. The findings revealed that the key actors have versatile motivations regarding autonomous shipping. These varied from opportunities for single applications to occupying a central role in an autonomous technology platform. Thus, autonomous shipping can be seen as an umbrella concept comprising multiple levels. In technical terms, the development of the concept of autonomous shipping is largely based on combining existing technology solutions, which are gradually integrated towards more systemic entities comprising areas of the autonomous shipping concept. This study argues that a service perspective embraces the inherently complex and dynamic nature of digital innovation. This is captured in the developed research framework that describes digital innovation emerging on different levels of interaction: 1. strategic relationships for new solutions, 2. new local networks for technology platforms, and 3. global networks for new markets. The framework shows how the business models and motivations of digital innovation actors feed the emergence of digital innovation in overlapping service ecosystems that together comprise an innovation ecosystem for autonomous technologies. Digital innovation managers will benefit from seeing their businesses as part of a larger ecosystem of value co-creating actors. In orchestrating digital innovation within a service ecosystem, it is suggested that managers consider the resources, roles and institutions within the ecosystem. Finally, as autonomous shipping is at its infancy, the topic provides a number of interesting avenues for future research.
